ABSTRACT
Problems arising from limited coarse aggregate sizes where by coarse aggregates are gotten from long distance quarry sites which have led to high cost of coarse aggregates and in turn resulted to high cost of construction. A synergistic combination of three sizes of coarse aggregates for concrete works was investigated in this research. For the purpose of this work, three sizes of coarse aggregates, 10mm, 14mm, and 20mm were used. Each of the sizes were cast which served as the control. The three aggregate sizes were also combined based on percentage proportion and cast. For each combined sizes of coarse aggregates, 21cubes (150×150mm) were cast to allow the compressive strength to be monitored at 7, 14 and 28 days respectively. Results showed that third test of the combined coarse aggregates which contained 30% 10mm, 20% 14mm and 50% 20mm had the highest compressive strength of 25N/mm2. Statistical T-Test analysis was introduced in this research to compare each of the control mixes with the concrete made with combined aggregates. It was seen from the analysis that, the value obtained which is 12.12 and
4.51 is greater than the T critical (4.303 at 5% level of significance) which also indicated that the third test of the combined aggregate had the highest compressive strength of concrete.
Assessment Of Effect Of Aggregate Sizes On The Comprehensive Strength Property Of Concrete Work
Appraisal Of The Implication Of Delays In Construction Project Delivery In Owerri
ABSTRACT
The Principle objective of this project is on Appraisal Of The Implication Of Delays In Construction Project Delivery In Owerri. The study delimited itself my limiting the scope into the roads maintained /constructed by the Setraco construction company in Owerri. This was deeply looked at by taking into account four major objectives that included: to establish the extent to which construction project financing influence the delay of construction projects in the road sector, to investigate the extent to which construction project planning influence the delay of construction projects in the road sector, to find out the extent to which Contractor’s experience influences the delay of construction projects in the road sector, and ,to investigate the extent to which supervision of work influences the delay of construction projects in the road sector. The study employed a survey research design, since it was an in depth investigation of an individual group of respondents. The questionnaires were used as the main source of gathering information from selected 55 respondents that cut a cross categories like Contractors, Surveyors, Engineers and many more. These questionnaires were emailed to some respondents; others were dropped and picked later while some were administered by research assistants. Questionnaires were sorted out, data keyed in into the SPSS for analysis. This information then was presented by use of frequency tables. From the hypothesis testing using the Chi-Square, the calculated Chi-Square values were found to be greater than the critical value of 9.488 thus the alternative hypotheses were adopted in all the four cases as per the objectives. Findings have shown that there is a significant link between the objectives discussed in the literature review and what is seen in chapter four and as it is entirely proven by the hypothesis that has been tested. Therefore, from the findings on the first objective that aimed at establishing the extent to which construction project financing influence the delay of construction projects in the road sector and the responses gotten showing that, 5 respondents agreed with the idea that the road projects have been allocated enough finances, 45 went for no while those who were not sure made 7.4% of the responses, bringing the total to 4 respondents. First and foremost, the study recommends that the federal government should increase the budgetary allocation to Setraco construction company. Secondly, the study recommends that Setraco construction company should undergo proper and checked planning at all levels in order to achieve timely deliveries. The third recommendation is that the experience of the contractors should be scrutinized, their track records be well understood and proper procedures of testing these contractor’s experience be checked. Finally, the study recommends that supervision should be continuous and in fact it should be made a daily activity. Absentee supervisors shouldn’t be even allowed to take part in any road construction in the country.
CHAPTER ONE
INTRODUCTION
- Background to the Study
According to Aon (2012), a project refers a series of task, arranged in a defined sequence or relationship that produces predefined output or effect and it always has a start and an end. In his writing, Aon looks at a project like a football hit from one point of the goal and aimed at achieving the objective immediately it enters the opponent’s goal; adding up to a score. He goes ahead to define the other major element of projects implementation that is called Construction Project Management (CPM). He defines Construction Project Management (CPM) as an approach used in the construction industry with the aim to increase the efficiency and effectiveness in performance in the management and coordination of a project during its lifecycle. Most construction projects usually suffer delay and surpass the outlined contract sum (World Bank, 2014). The result of such overrun can at time lead to abandonment of a project. Ideally projects are supposed to run continuously without delays and the responsibilities to keep this in check lies squarely with the project manager and other stakeholders who are linked directly with the projects. Within the project team there should be an outlined strict mechanism discouraging parties to the project from laxity that may lead to stalling or delays (Oyewobi, et al.2011).
In my study, the major projects am going to look into are infrastructural projects. Infrastructure can be categorized into “hard” and “soft” infrastructure. The former refers to physical structures or facilities that support the society and economy, such as transport (ports, roads and railways); energy (electricity generation, electrical grids, gas and oil pipelines); telecommunications (telephone and internet) and, basic utilities (water supply, hospitals and health clinics, schools, irrigation). The latter refers to non- tangibles supporting the development and operation of hard infrastructure, such as policy, regulatory, and institutional frameworks; governance mechanisms; systems and procedures; social networks; and transparency and accountability of financing and procurement systems (Oyewobi & Ogunsemi, 2010). Globally, infrastructure is an important factor in the development of a nation through its direct and indirect contributions to economic growth. According to a World Bank (2014) the following three factors of infrastructure fosters economic growth: infrastructure directly or indirectly reduces costs in the production process, infrastructure induces structural change which influences production and consumption trends; and infrastructure contributes to sources of income and better income levels.
However, reports across the developed and LDCs has shown the construction projects like roads and other infrastructures have been faced with a major common problem of ‘delays in delivery.’ According to Nyamwaro (2011), Construction project delivery is affected by many factors. Every investor wants to be sure of the project time and cost. This is because challenges that may affect project completion have far reaching effects ultimately on the owners’ interest. Chism and Armstrong (2010) in study carried in USA aver that in the current economic landscape, project owners are scaling down or eliminating capital construction projects due to lack of financing, uncertainty over costs, and concerns about potential delays that could impact the feasibility basis of projects. While in a study carried out in the UK Fapohunda and Stephenson (2010) state that in construction, conflicts exists between the projects’ stated objectives with regard to the appropriateness of cost time and quality. They also identify the distinct knowledge management areas for project managers’ efficient performance to include among others project time management which includes providing an effective project schedule for project delivery besides actually delivering on the schedule.
Chism and Armstrong (2010) for example studied the construction of the proposed road network in the Illinois states that was to be funded by the US government and the county development assembly between 1994 and 1999. They discovered that the road prolonged by 3 more years; meaning additional expenses/overrun coasts, negative impact to the community and political repulsion from the Democrats. They cited two major caused of this delay as those coming from the natural environment (Hurricane Katrina, hails stones, ice caps, extreme cold weather etc.) and human caused factor ( insufficiency of financial resources, change in technology, politics etc.). McNair (2011) referring to the Australian context of applying EPC contract advances the importance of a contractor delivering a complete facility for a guaranteed price and by a guaranteed date. He looked at the construction of feeder roads in the city of Newcastle and argued that, up to 30% of the projects failed due to weather situations that faced the cold desert continent between 2000 to 2005, the political indifferences between the upper house and the construction industries, newly adopted technology from China, expertise demands, financial constrains due to the economic crisis of the millennium and many more. He further observed that failure to achieve this completion of roads construction will usually result to a contractor incurring monetary liabilities. The subject of completion of project is therefore a universal concern that affects all parties to a construction project (Musa, 2012). It is thus in the interest of the project management as an emerging profession to address all the factors that affect completion of construction project. The contractor usually has a limited ability to claim additional money which is limited to the circumstances where the project company has delayed the contractor or has ordered the variation of the works (McNair, 2011).
In a study carried out in Johannesburg South Africa, Ahmed, Azhar, Castillo and Kapagantulla (2012) state that delay of roads construction projects in all the cities and slums of SA are indeed a universal phenomenon. They are also most always accompanied by cost and time overruns. Roads Construction project delays in South Africa just like any other countries further have a debilitating effect on all parties (owner, contractor, and consultant). It is therefore correctly deduced that factors affecting construction project completion is a study of interest to all parties. This in agreement with Karim & Marosszeky (2012) observation that project delays have been a topic of concern in the construction industry. In their studies, they for example observed that up to 45% of the roads upgrading projects in troubled Soweto slums were not delivered in time between 2004 to 2009 due to factors that ranged from: political disagreements especially when refugees from Zimbabwe infiltrated into the country, Thabo Mbeki’s failure to command the majority votes in the ANC that could favour him in allocating this project funds, the regular strikes by mines led the partners walk away in the view of bad governance, corruption, low level of technology applied in construction industry etc. According to The World Bank (2014), the political issue-especially-with the uprising Malema and his opposing youths has left up to 30% of roads unattended because the youths feel that the tenders were irregularly awarded.
Hussin and Omran (2011) state that in Nigeria, seven out of ten roads construction projects in Borna and Kano Plains surveyed suffered delays in their execution. Also Fugar & Agyarkwa (2010) observed that in Nigeria 5-10% of construction pre-contract cost is based on contingency. This has been found inadequate which means extra financial commitments occasionally beyond the capacity of the owner. Clients are sometimes not prepared for this and so fund in terms of loans are sought to offset this additional costs. It is in this agreement that Chiocha (2011) argues in his book, ‘Corruption and its effects on the development of the construction industry in Nigeria’ that, up to 78% of the roads in rural Nigeria and its northern part will be under dust for the coming 15 or more years because of factors that can be controlled like: corruption from the local chiefs (Ogas), governors, federal government, NGOs and many more. In his writing, Chiocha tends towards the argument that up to 60% of the roads have failed to meet deadlines due to corruption that leads to poor contractual awards, misappropriation of little funds, poor expertise selection, poor technology employment and many more.
In a study carried out to examine roads construction projects performance in Sudan, Omran (2012) observe that despite large number of reported cases, construction ranging from the simplest to more complex roads projects platforms have increasingly experienced cost overruns due to silly delays that could be prevented up to 95%. This phenomenon is also similarly observed in Ghana and Uganda where Gaba (2013) observes that studies reveal increase in cost overruns, delayed completion,
unsatisfactory and unmet roads project objectives in most construction projects. While investigating the subject of roads projects delays in Sudan and Uganda, Olatunji (2010) observes that it is a phenomenon that can be attributed to the inability of the client/his representative and the project team to have a comprehensive view of the construction project from inception to completion. Aibinu and Jagboro (2012) state that construction delay has become endemic in Nigeria, Sudan, Uganda, Eritrea etc. Delay they found out had significant impact on completion cost and time of 61 building projects studied.
In Nigeria, building and construction industry has been robust (Nigeria facts and Figures, Nigeria Federal Bureau of Statistics, 2012). Foreign investors have shown a lot of keenness to have a stake in Nigeria considered a business hub in east and central Africa and a center from which they can operate within Africa. As a result of this, major cities like Nairobi, Mombasa, Kisumu and their environs have witnessed a boom in construction projects especially those addressing locomotive infrastructure. These projects are government, private individuals, private companies and interfederal businesses and institutions sanctioned. Remarkably is the Thika super highway. In his research about roads infrastructure in Nigeria, Mbogo (2011) argues that, Road construction industry plays a major role in development and achieving the goals of the Nigeria’s society. Roads Construction is one of the largest industries and contributes to about 10% of the gross federal product (GNP) in industrialized countries (Maxwell, 2012), and 6.1% LDCs like Nigeria. Construction industry has complexity in its nature because it contains large number of parties as clients, contractors, consultants, stakeholders, shareholders and regulators. The performance of the construction industry is affected by federal economies (Kikwasi, 2012).
A report done by the GoK (2012) and Work Bank (2013), In Nigeria, the construction of Thika Superhighway for example which was set to be completed in the year 2011 was realized a year later. The deadline was moved twice resulting in both cost and time overruns. The project cost kshs.7 billion more than the original budget. Major citations of the factors of delays were not limited to: political differences and heat in the coalition government, lack of community involvement ,bad weather conditions as a result of el-Niño rains of 2011/2012, poor technology that came from the local sub-contractors, economic fluctuation; owing to the factor that the project was never hedged etc. A closely cited project that was never completed in time due to the issue of financial resources and technology (GoK, 2013) is the construction of Greenfield terminal at Jomo Nigeriatta Interfederal Airport, that had its start date postponed several times which make the project far behind its schedule at the moment (The Quantity Surveyor and Construction Claims, 2011). This had an overall negative impact to the government which lost almost Ksh.98, 324,900 as inconvenience adjustments.
A feature of road Construction Firms in the Mombasa is that, they are often believed to be one-man enterprises, having low financial and capital base and also lacking the requisite managerial skills to adequately face up to the numerous and difficult challenges they constantly have to encounter in a typical developing economy such as Nigeria’s (Chilipunde, 2010). Due to this lack of enough expertise and lack of sufficient financial resources, there is a number of roads constructions/maintenance that has stalled for ages now. In his writing, Waihenya (2011) argues that the delay in implementation of development projects like roads, electricity, water and sewerage projects in the Nigeria’s coast date back to the Arabs and Portuguese infiltration into the region who made the region dependent on the ideas of the masters, live at their comfort zones, reject any European associated technology and be in constant religious repulsion among themselves. His has been a challenge for example for the roads construction sector to get enough support from the community in terms of expertise, dedicated laborers, modern technology, necessary development resources, political support and many more.
Official statistics indicates that, indeed, these so-called small firms represent over 95% of contractors operating in the Nigeria’s economy (Ahadzie, 2011). In Nairobi County for example, most contractors, particularly road contractors have shown a lot of interest in the sector. Although, most of these firms have been performing minimally but they have an impact in Nairobi than Mombasa. In Mombasa, 20% of the local construction firms are owned by the local Arabs and Swahili community while the Mijikenda community shares only 5% and the greater percentage is left to the foreign companies from established towns and cities like Nairobi (Chai & Yusof, 2013).
- Statement of the Problem
Many road contractors whether from the government agencies or limited local firms have failed or perform minimal in their performance, particularly in maintenance of road. The criticism against their performance has attracted the government attention forcing it to come up with performance contract and even settling the authority to oversee the contractors ‘performance’. However, according to government of Nigeria (2012) the poor performance of the road contracts is due to poor management of funds and poor delivery of services to the road user. In addition, performance measurement systems are not effective or efficient to overcome this problem. Road contractor’s performance problem appears in many aspects, ranging from fail in time performance, cost performance and others fail in other performance indicators. Ugwa and Haupt (2007) opined that the failure of any road contractor is mainly related to the problems associated with resource management and even political interferences. Moreover, there are many reasons and factors which attribute to this problem including poor management of the minimal resources available, low levels of technology that make the whole exercise very expensive, politics and many more.
In Nigeria, there are many road contractors who have failed in performance. In the past, many road projects were finished with poor performance because of many contractors’ reasons such as: obstacles by client, non-availability of materials, roads closure, amendment of the design and drawing, additional works, waiting the decision, handing over, variation order, amendments in Bill of Quantity and delay of receiving drawings (Wambugu, 2013). For example, project of rehabilitation of Waiyaki highway finished with problems in both of time and cost performance (GoK, 2010). In addition there are other indicators of performance such as project managers, coordination between participants, monitoring, and feedback and leadership skills. However, there are three important issues related to failures and problems of performance in Nigeria which are economic, environmental and socio-cultural issues like politics. Local studies done by Musa (2012) on effects of total quality management on performance of Companies in Nigeria a case study of Julius Berger Company Limited. He found that human resource management and resource management affects performance of the building company to a great extent.
Purpose of the Study
The study seeks to investigate determinants of projects completion in the construction industry; the case of selected road projects implemented by Nigeria Federal Highways Authority in Owerri Municipal .
- Objectives of the Study
The objectives of the study were:

The research was guided by the following questions:
- To what extent does construction project financing influence the delay of construction projects in the road sector?
- What is the extent to which construction project planning influence the delay of construction projects in the road sector?
- To what extent does the contractor’s experience influences the delay of construction projects in the road sector?
- What is the extent to which supervision of work influences the delay of construction projects in the road sector?

- H1: Construction project planning has a significant influence in the delay of construction projects in the road
- H1: Contractor’s experience has a significant influence in the delay of construction projects in the road
- H1: Supervision of work greatly influences the delay of construction projects in the road sector.
- Significance of the Study
This study will help construction professionals increase the success of construction projects completion by managing well the factors that will help their successful completion. The architects, engineers, quantity surveyors, construction project managers and site agents may benefit from this study by applying the results of its findings while carrying out construction projects.
The government will be aware of the factors that cause delay in roads construction projects and ways of addressing those delays so as the roads construction process is harmonized therefore efficiency in the production of this gold infrastructural facility.
Project developers/clients may also benefit from the findings of this study and therefore achieve greater success in their construction projects. This is because they may apply the findings of this study in ensuring the risk factors that may cause their projects not be delivered successfully are mitigated.
- Limitations of the Study
This study was faced by the challenge of time which was a constraint. Time between studies, research and work were somewhat competing, though extra time was sought to compensate for this. The study also was faced with the challenge of inadequate budget. The unavailability of budget also negatively affected the study. Therefore an alternative source of finances was sought.
- Delimitation of the Study
The research study limited itself to roads construction projects in Owerri under Setraco construction company in the Nigerian. It further selected only five projects from the Owerri municipal that have had their projects delayed for a long time.
Definitions of Significant Terms
Construction project completion-this refers to successful carrying out of a construction project as per the time agreed to in the contract agreement and as captured by the project schedule, within the budget and design scope.
Project- an overall task which has a definable beginning and definable end, it consists of a number of related and dependent activities, all of which utilize resources and upon which there are imposed internal and external conditions.
Project delay- The delay referred to in this study is the failure of government road construction projects to meet standards, to reach target group, cost and time overruns.
Project financing- this refers to the ways that a client provides the funds that cater for the cost of design, planning, labour and approvals required to ensure the construction project is successfully carried out.
Project performance- This is an aspect of project accomplishment in regard to the subjective matter of the client and the public at large.

CHAPTER ONE
INTRODUCTION
1.1 Background to the Study
Heavy metals are elements with specific gravity greater than 5.0. They are metals which can be toxic even in small concentrations. Heavy metals are introduced into the environment through many sources such as weathering of rocks and soils; volcanic eruptions and various forms of other human activities involving mining, processing or use of metals and other substances containing contaminants (Lincoln et al., 2007; Ewuim and Akime, 2012). According to Biney et al. (2005), heavy metals are partitioned between water sediments, suspended solids and aquatic biota in water bodies and tend to accumulate more in sediments than in aquatic organisms and water as such sediments acts as sinks and supply of heavy metals to overlying water columns (Brooks et al., 2010, Gbem et al., 2001). When heavy metals enter water bodies, they change water quality, bind to sediments and accumulate in aquatic biota causing anemia, disturbance of physiological functions and mortalities of fish (Baeyans et al., 2001; Eichler et al., 2006). Specifically, aquatic organisms experience histo- logical and morphological changes in circulatory systems, biochemistry, physical behaviour and organism’s reproduction (Kedebe and Wondimu, 2004; Olaifa et al., 2003).
The introductions of toxicants into an environment where fishes are found stun them and or acts as a stressor on the fish and other organisms found in that environment (Capar and Yess, 1996, Kakulu et al., 1987). The toxicants in water bodies may dissolve the oxygen concentration which eventually impairs aquatic organism respiration thus leading to asphyxiation. Reproduction is also impaired during bioaccumulation of toxicants (Mayer, 2001). As water temperature increases, rate of biological processes increases and may result in increase in metal uptake by fish and gram (g) hydrogen Ion concentration (pH). As pH decreases, more dissolved metals ions are produced. Ionic forms of heavy metals induce acute poisoning in aquatic animals leading to immediate fish kills while complex forms lead to chronic poisoning and bioaccumulation in fish tissues over a longer period (Ellis et al., 1989; Baeyans et al., 2005).
Toxicology testing is conducted to determine the degree to which a substance can damage a living or nonliving organisms by analyzing the actual chemical in the samples or the used laboratory animals in studies. It has been in use for a long time in detecting potential hazards effects chemicals can have on living organisms via bioaccumulation of level of toxicants. The measure of a chemical’s toxicity is its Median Lethat Dosage (LD50) value which is the concentration that can cause average kills of 50 percent of a test population of animals on trial. This is usually reported in milligrams of the chemical per kilogram of a test animal’s life weight. The smaller the values, the more toxic the chemical referred. Chemicals with LD50 values greater than 500mg/kg in rats or mice are generally considered safe in agriculture (Mayer, 2001; Cunningham et al., 2011; Hadioui et al., 2005). Heavy metal pollution of water has become a major environmental problem since the advent of agricultural and industrial revolution and today most water bodies are contaminated with heavy metals released from domestic, industrial and other man-made activities. In modern times, one of the main threats to the health of ecosystems is the exposure to a myriad of toxic substances and compounds such as mercury, cadmium, lead, copper, arsenic, air pollutants, pesticides, plastics, cigarette smoke, diesel fumes and nano-particles found in products like perfumes and sunscreens. Their introduction into aquatic environment is caused by direct or indirect agricultural and industrial discharges (Zhang et al., 2009; Von Linden et al., 2003).
Heavy metals contamination could be detrimental to ecological balance of the recipient environment and to a diversity of aquatic organisms. Lead is a heavy metal which can seriously harm the human central nervous system, especially in children. It damages the kidneys and the immune system very easily. Exposure to lead causes premature births, diminished mental ability, mental retardation in infants and children making learning difficult and reduced rates of growth (Hu, 2000). Lead has been identified in at least 1,272 of the 1,684 hazardous waste sites that have been proposed for inclusion on the Environmental Protective Agency (EPA) National Priorities List (NPL) (Schmitt and Brumbaugh, 1990; Herbert, 2004; WHO, 2006). The majority of cases of lead poisoning are due to oral ingestion and absorption through the gut. Lead poisoning in adults occurs more frequently during exposure in the workplace and primarily involves the central nervous system. Symptoms of hemopoietic system involvement include hypo chromic anaemia with basophilic stippling of the erythrocytes, hyperactivity, anorexia, decreased play activity; low intelligence quotient and poor school performance have been observed in children with high lead levels (USEPA, 1998, USEPA, 2002). Lead crosses the placenta during pregnancy and has been associated with intrauterine death, prematurity and low birth weight (Leighton et al., 2003; Kris-Ether ton et al., 2003; Nriagu et al., 1996).
1.2 Statement of the Problems
Since fish is an animal that is particularly affected by these pollutants, different species have been widely used to evaluate the health of aquatic ecosystems (Hu, 2000; Igbal et al., 2008; Laidlaw et al., 2005; Mohammed et al., 2011). Fish is of paramount importance in many nations’ economics and food proteins. In a few countries in the world, fish consumption contributes up to 180 kcal per capita per day, but reaches such high levels only where there is a lack of alternative protein foods grown locally or where there is a strong preference for fish. Nigeria current national fish demand is around 1.6 million metric tons and it is supplied from imports about 700,000 MT per year while domestic production is 640,00MT from both marine and freshwater (FAO, 2006, 2007). Fish proteins are essential in the diet of some densely populated countries where the total protein intake level is low, and are very important in the diets of many other countries in the world. Fish is also a valuable source of essential fatty acids and its protein is highly and easily digestible to man. Even in small quantities, fish will have a significant positive impact on improving the quality of dietary protein intake by complementing the essential amino acids that are often present in low quantities in the rice and vegetable diets which are typical of nay developing states food. Fish is a rich source of lysine and other essential acids that are often deficient in carbohydrate diets and other plant protein sources (Lovell, 1988).
Fish meal is essential feedstuff rich in the essential proteins and essential amino acids nutrients needed by cultured fishes. In fact, livestock and fish feed without fish meal cannot meet the required nutrients for good performance of any of their culture animal (Lovell, 1988; Falayi, 2009). Recent research shows that fish is much more than just an alternative source of animal protein. Fish oils are the richest source of a type of fat that is vital for brain development in unborn babies and infants and cardiovascular therapy (Kris-Etherton et al., 2003). This makes all fish and especially fatty fish, such as tuna, mackerel and sardine, particularly good components of the diet of pregnant and lactating women. It is therefore apparent that fish makes a valuable contribution to the nutritional quality of the diets of the populations of many developing countries in Asia and the Pacific region (FAO, 2006, 2007). Clarias gariepinus is a hardy fish and highly valued in Nigeria. Catfishes of the family Claridae comprise the most commonly cultivated fishes in Nigeria (Adesulu, 2007). The growth of aquaculture in Nigeria now is largely being boosted by a steady rise in catfish culture. It is therefore very important to guide our environment jealously from been polluted by the uncontrolled use of contaminated inland waters for aquaculture purposes as well as our territorial waters from oil spillages from petroleum exploration.
1.3 Aims and Objective of the Study
The main thrust of this research is to investigate the Disposition Time Of Cadmium And Lead Within The Tissue Of Medium Sized Clarias Garienpinus
1.4 Scope of the Study
The study is to ascertain the quantity of lead that can be accumulated within medium sized clarias garienpinus tissues and the implication in fish. This would then give an indication of how lead is indirectly consumed by man, the ultimate fish consumer.
1.5 Definition of Terms
Cadmium.: a toxic bluish-white malleable ductile divalent metallic element used especially in batteries, pigments, and protective platings
Disposition : This is the way living thing tend to behave or feel
Clarias gariepinus: This is a species of catfish of the family Clariidae, the airbreathing catfishes.
Lead: This is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials.
Tissue: this are groups of cells that have a similar structure and act together to perform a specific function
AN ASSESSMENT OF THE PROPERTIES OF CONCRETE MADE WITH CERAMIC WASTE AS AGGREGATE
ABSTRACT
The quantity of ceramic waste tile in Nigeria has been on the increase without consideration for potential reused or recycling. This increases the risk to public health due to the scarcity of land area. The growing problem can be solved if new disposal option other than landfill can be found. Continuous dependence on conventional materials for concrete is also leading to scarcity of its materials resulting to increase in construction cost. This research was carried out to establish the suitability of ceramic waste tile as aggregate for concrete production. Ceramic waste tile originate from broken, scrap and leftover tiles. The replacement proportion was 100% for both fine and coarse natural aggregates. A total number of 100 cubes were cast using nominal mix ratio of 1:2:4 with water cement ratio of 0.55 and tested for compressive and split tensile strength at 7, 14, 28 and 56 days. Abrasion resistance and water absorption tests were carried out at 28 days of curing age. The results showed that at 28 days the compressive strength was 22.27N/mm2 and 19.46N/mm2, and split tensile strength of 2.94N/mm2 and 1.94N/mm2 for ceramic waste tile concrete and that of conventional concrete. This research concludes that the ceramic waste tile concrete has a higher strength and durability than conventional concrete and also recommends that the ceramic waste tile can be used as an alternative construction material for fine and coarse aggregate

CHAPTER ONE
1.0 GENERAL INTRODUCTION
All over the world, the public service as a matter of experience has not been known for their capacity to create wealth. Consequently, public enterprises have usually been perceived as drain pipes, thus creating budgetary strains and avoidable burden on the economy. It became a national policy imperative therefore to disengage the public sector from those areas where the private sector has the comparable advantage to perform, while letting the State concern itself with the provision of infrastructure, security and the enabling environment for business to thrive through enhanced wealth creation.
It is important to observe that for many developing countries like Nigeria, it was perhaps unavoidable for the government, in an earlier epoch, to promote the initial investments in the early phase of national development when the private sector was almost non-existent. Unfortunately, the government got herself so involved in business that could best be tackled by the private sector, that government could no longer perform her traditional functions: the provision of infrastructure and security through the maintenance of law and order as well as the promotion of an enabling and conducive environment for investments and wealth creation. (Any a, O. A., 2000 p4)
1). The import of this economic step is anchored on “the belief that entrepreneurs can manage the industries and can operate services more efficiently and at a lower cost than the public enterprise. (Onodugo,V.A. 1995 P3).
The introduction of privatization fourteen (14) years ago has provoked a lot of public attention and discussion. However, it is clear that as opposed to the 1980s when there were two strong schools of thought on privatization – one for and another against, dissenting voices are much fewer these days. This perhaps, may be an indication of the widespread acknowledgement and
acceptance that the merits of privatization far outweigh its demerits.
It is therefore the purpose of this study to critically analyze this government policy of privatization and commercialization, with a view to finding out whether it has the economic remedy, for which it is meant. In doing this, the researcher will carry out investigation using two government parastatals namely – The Nigerian Telecommunication Limited (NITEL)
STATEMENT OF THE PROBLEM
The economic depression of the late 1930’s with it’s deep and severe consequences coupled with the revolution in the Union of Soviet Socialist Republic (USSR) led to a situation where governments, that hitherto had no business in running enterprises, dabbled into business. This became possible when private sector enterprise, especially in Western Europe collapsed due to the recession.
Nigeria, like many African countries on attaining independence, embarked on establishment of public enterprises. The oil boom of the 70’s further accelerated the growth of the public enterprises. Government presence was felt in virtually every aspect of our economy such that “it became the largest producer, the largest consumer, the biggest employer, the biggest owner of property, the biggest investor, the biggest insurer and the biggest debtor’ (Ubaigboma 1995 P. 8).
However, by the 1980s, it was clear that a nightmarish mistake has been done indicated by the common features of the public enterprises, which are huge annual losses, gross inefficiencies, low returns, mismanagement etc. All these necessitated a move towards competitive market system by the use of economic tools of domestic Deregulation, Privatization (Iromantu,
1999).
Privatization has become a major element of economic reform and an important instrument for advancing the global competitiveness of nations. It is therefore, the problem of this study succinctly examine and analyze the extent to which the objectives of the privatization programmes have been achieved with special reference to the Nigeria Telecommunication Limited (NITEL)
The above problem brings to the fore the following sub-problems: –
1. What effect will the privatization of public enterprises have on the economy of Nigeria?
2. Whether the privatization programmes has improved management efficiency?
3. Whether the parastatals have achieved the much-needed economic objectives for which it was set out to pursue?
4. Are the structures put in place for the proper implementation of the privatization programme adequate?
5. What do the general public stand to benefit from the privatization programme?
OBJECTIVE OF THE STUDY:
The main aim of the study is on Technology Management Lessons From The Privatization Of NITEL (NIGERIA TELE COMMUNICATION LIMITED)
The specific objective of this research work:
1. To identify any organizational structure of NITEL that is interfering with the effective realization of the objectives of the privatization programmes.
2. To examine the incessant interference of government and their agencies on these parastatals and establishing whether it contributes to their inefficiency.
3. To ascertain the public assessment of the economic policy, using their perception of the services rendered by NITEL .
4. To examine the reasons these public enterprises suffer from lack of purpose, role conflict and misplaced objectives.
5. To determine the extent to which the privatization programme have had a positive impact on the operations of NITEL .
RESEARCH HYPOTHESIS:
For the purpose of achieving a reasonable degree of accuracy and relevance in this research work, the following hypothesis have been posited and tested.
1. That NITEL have not attained higher productivity levels since implementation of privatization and commercialization.
2. That there has been no improvement in economic growth as indicated by increases in government income, per capita income and GDP since the implementation of the programme.
3. That there has not been marked improvement in the management efficiencies of NITEL since privatization and commercialization.
4. That the services rendered by NITEL have not improved reasonably since the privatization programme was implemented.
SIGNIFICANCE OF THE STUDY
The services sector has enlarged to become a dynamic sector whose importance has continued to rise in most economies in the late 1980s and the 1990s. The sector currently represents over 60% of GNP in most of the developed economies. There is no doubt that these public enterprises are growing in importance over the years. In Nigeria, the number of public enterprises has increased tremendously and now occupies a central position on the economy and has therefore become major instrument of development (Project Work).
These have necessitated increasing investments in these enterprises by the government but inspite of these investments, the returns have been extremely poor. The public sector has thus gained the reputation of constituting sources of waste, and being inefficient coupled with bad attitude to work, undue interference, corruption and low morale.
It is therefore the objective of this study to determine the root cause of these problems and to proffer probable solutions or directions to follow. In the view of this, it is therefore hoped that the study of the effect of the privatization programmes in two parastatals NITEL both in Enugu, will help the management and indeed the government in the formulation of effective policies to enable them continue the implementation of these programmes.
It is also hoped that workers, the society and especially scholars who might wish to conduct further research on the subject matter in the future will find it very reliable.
SCOPE AND LIMITATIONS OF THE STUDY:
.
Whenever a research of this nature is being conducted, there is bound to be some constraints militating against the study.
A major area of limitation was the attitude of respondents most of which were non-cooperative, nonchalant, illiterate and ignorant about the subject of study and this heavily hindered the completion of the questionnaires.
Another major area of limitation was the unavailability of secondary sources of data considering the fact that both parastatals are yet to be privatized.. This constituted a major set back as there was basically nothing on which judgments and inferences could be based on.
Finally, this study was also constrained in terms of time, money and logistics and of which none came cheap.
HISTORICAL BACKGROUND OF CASE STUDY:
THE NIGERIAN TELECOMMUNICATION LIMITED (NITEL), ENUGU
The Nigerian Telecommunication Limited (NITEL) started as a postal branch of the British Post Office in 1851 and in 1885 an internal telecommunications arm with better system of telecommunications was established to serve the interest of the colonial masters. In 1966, the Postal and Telecommunications (P&T) a quasi- commercial department of the Ministry of Communications was formed and backed by Decree 22 of the miscellaneous provisions. In 1985, the Nigeria Telecommunications limited was formed.
The external telecommunications concerned with the provision of direct telegraph services between Nigeria and London, made possible hi 1886 by the African District Telegraph (ADT) and the Cable and Wireless Company of London. In 1997, the Federal Government acquired 51% equity ownership of the Cable and Wireless Company and changed its name to Nigerian External Telecommunications (NET) Limited. By 1972, the government acquired the remaining 49% and made it a Federal Government wholly owned company which was to provide external telecommunications services.
In 1984, P&T and NET were merged and incorporated as a Limited Liability Company under the companies Decree of 1968.
This merger saw the birth of the Nigerian Telecommunications Limited (NITEL), which officially kicked off on 1st January 1985. On 22nd May 1992, there was a contract agreement between the Federal Government, NITEL and the Technical Committee on Privatization (TCPC), now known as the Bureau of Public Enterprises (BPE). This agreement marked the beginning of the era of Privatization of NITEL, which will now become NITEL Plc.
On incorporation, the company had an authorized share capital of N 4,000,000 shares of N 1.00 each with N 2,000.000 fully paid up by Government. This was reviewed in 1992 when the company was re-registered as a Public Limited Company with an authorized share capital of N 5.5 billion all of which was fully paid. In almost a century of providing telecommunications services, Nigeria could boast only of 250,000 lines most of which were of the analogue technology. The transmission link was also mainly of the analogue system while the two gateways located at Oyo State and Kaduna State were aging and going out of fashion.
NITEL was also characterized with other problems such as undue interference from the government, labor turnover, management inefficiency, fraudulent practices by some staff, abandoned projects, uneconomic investment decisions, low returns, inadequate network capacity, low tariff structure and delayed dial tone. To overcome these problems and more, long term development strategies were mapped out during the formative years, but these strategies hardly saw the light of day because of the limited power of NITEL, as they relate to decision making and policy implementation.
To overcome these, the Government decided to embark on commercialization of the company, which took off in May 1992. This action granted NITEL autonomy especially as regards business oriented and customer oriented decisions. This enabled it embark on network expansion and to adequately maintain existing facilities and modernize others. The effect of these developments resulted in the provision of digital facilities in Abuja (20,000 lines), Lagos (45,000 lines), Kaduna (10, 000 lines), Enugu (30, 000 lines) and Ibadan (25, 000 lines).
NITEL also extended its services to the rural areas with the installation of digital exchanges using the colophony technology. On the part of International Connectivity, NITEL established dual antenna (digital) satellite earth stations in Lagos and Enugu and a third to be finished in Kaduna. In addition to the conventional services of telephone, telex and fax, NITEL also introduced value- added services like Mobile Cellular Phone System, Voice mail, Paging Services and Internet services.
CORPORATE SOCIAL RESPONSIBILITIES OF SHELL PETROLEUM DEVELOPMENT COMPANY (SPDC) AND NIGERIA AGIP OIL COMPANY (NOAC) FOR SUSTAINABLE COMMUNITY DEVELOPMENT IN RIVERS STATE
ABSTRACT
This study examined the Corporate Social Responsibilities (CSRs) of Shell Petroleum Development Company (SPDC) and Nigeria Agip Oil Company (NAOC) for Sustainable Community Development in Rivers State. Five research questions and three null hypotheses were posed for the study. The research design adopted was the survey design. The population of the study comprised of the Community Development Committee (CDC), Shell and Agip Community Liaison Officers (CLOs) who were the indigenes of the oil communities. The populationalso include staff of the Corporate Community Relation Department of SPDC and NAOC. The total sampled size was 731 respondents representing 35% of the targeted population. The instruments used for data collection were questionnaire, focus group discussion and interview. The research questions were analyzed using percentages and mean statistic. T test was utilized in testing the hypotheses at 0.05 level ofsignificance. The result of the study revealed that Shell CSR was not well known by the host communities,while Agiphave CSR for sustainable development of their host communities. Shell and Agip through CSR contributed positively in resolving conflicts in their host communities. Shell through CSR could not contribute muchto socio-economicdevelopment of the host communities while Agip through CSR contributed to socio-economic development of their host communities. The companies (Shell and Agip) through CSR could not mitigate the environment of their host communities. Based on the findings the following recommendations were made: Oil companies should recognize their responsibilities, the host communities expectations and develop partnership as preferred model for their community development activities for peaceful co-existence. The oil bearing communities should try as much as possible to be a good host to these oil multinational companies by providing a safe and conflict free environment for them. The government should provide an enabling environment for sustainable development through CSR principles and practices and also leading by examples
COMMERCIAL BANK LENDING TO SMALL AND MEDIUM SCALE ENTERPRISE (A CASE STUDY OF UNION BANK OF NIGERIA PLC, ENUGU)
ABSTRACT
The critical causes on why financing small and medium scale industries by commercial banks in Nigeria have not been very effective were evaluated. Not only are the SMEs starved with financial back-up, they are also faced with other external problems such as high interest rates, inconsistency in government industrial policies, lack of infrastructural facilities and internally; poor management practices, high rate of business failure, poor accounting standards, shortage of skilled manpower and financial indiscipline.
In view of these numerous problems, this research work was conducted so as to come out with solutions as this will pave way for banks to have more confidence in financing these SMEs efficiently and effectively as against hitherto , their stringent lending policies and the risk averse behavior of funding. This has become necessary as it is a well known fact that the survival, growth and development of SMEs of any country depend largely on funding with other factors put in place.
In the light of the findings in this research work, some recommendations and suggestions were made to the government, commercial banks and the small and medium scale entrepreneurs themselves which if implemented will not only sustain the survival, growth and development of this sector, it will also provide employment opportunities and improve the economic situation of Nigeria.

ASSESSMENT OF BENEFITS AND CHALLENGES OF NATIONAL HEALTH INSURANCE SCHEME ( NHIS) AS A TOOL FOR ACHIEVING UNIVERSAL HEALTH CARE IN KWARA STATE NIGERIA
ASSESSMENT OF BENEFITS AND CHALLENGES OF NATIONAL HEALTH INSURANCE SCHEME (NHIS) AS A TOOL FOR ACHIEVING UNIVERSAL HEALTH CARE IN KWARA STATE NIGERIA
ABSTRACT
National health Insurance Scheme (NHIS) is a health care scheme established by the Federal Government of Nigeria in 2005 for better healthcare delivery to its populace. The main thrust of the study is on Assessment Of Benefits And Challenges Of National Health Insurance Scheme ( Nhis) As A Tool For Achieving Universal Health Care In Kwara State Nigeria. Questionnaires were administered randomly to 200 adult respondents in Kwara metropolis. The findings show that only 24% of adults were enrolled in the scheme. Notably, 82% of enrolled respondents were aware of NHIS and prefer it to the fee for service system. There was some level of dissatisfaction in the scheme (26% of enrollees). Sources of dissatisfaction included poor registration services, poor referral system, delays in receiving required services and unavailability or non coverage of some required services. It was statistically determined by the Chi Square tool of analysis that there was a direct relationship between the percentage of enrollees and the poor health indices of the populace. We strongly recommend modification of existing policies to enable enrollment of the self employed and unemployed as well as improved coverage and quality of services within the scheme.
CHAPTER ONE
INTRODUCTION
1.1 Background to the Study
Several approaches abound in financing healthcare. These range from fees for service to private insurance, general taxation, social insurance, community financing, loans and grants. In Nigeria, combinations of all these in different proportions have been practiced for decades. The most basic form of health care financing is that of fees for service, where a fee is charged to cover all or part of the cost of the service provided. In many low and middle income countries a fixed fee for service, known as a user charge, is used by government health facilities, both as a means of raising revenue and as a means of discouraging what may be viewed as ’unnecessary demand’. This form of health care financing has a number of disadvantages. The direct payment of fees for service is regressive in that it causes the greatest hardship for the poor, and may cause major difficulties in payment for waged labourers, who are unpaid during sickness (Goodman, 1993).
The rising cost of health care services as well as the inability of the government health facilities to cope with the people’s demand necessitated the establishment of National Health Insurance Scheme (NHIS). The start of the NHIS dates back to 1962 when the need for health insurance in the provision of health care to Nigerians was first recognized (Akande and Bello, 2002; Katibi and Akande, 2003). It was fully approved by the Federal Government in 1997, signed into law in 1999 and launched officially on the 6th June 2005. The Scheme is designed to provide comprehensive health care delivery at affordable costs, covering employees of the formal sector, self employed, as well as rural communities, the poor and the vulnerable groups a fee for service system with government funds supplementing in capital project financing. External loans and grants in form of technical assistance and free drugs especially for preventive services are common in Nigeria. The Global fund for HIV/AIDS, Malaria and Tuberculosis is one of such initiatives. Immunization campaigns are also supported by donor agencies. So far, the common man is yet to get the best of healthcare in Nigeria. The fee for service system takes so much from his pockets and leaves him unprepared for most medical expenses.
As a result of the possibility of very high and unpredictable medical costs, many users of the fee for service system arrange cover through private insurance schemes, where the risk of illness is pooled among the insured group. Private insurance schemes attempt to spread the risk of illness over all insurees and as such discriminate less against the sick than pure fee based systems (Green, 2007). Social insurance schemes on the other hand widen the base of private schemes with payments tied to wage levels. Contributions to the scheme are made by employees, employers, and in some cases the state. This system is identical for all enrolees, and the premiums are based on income rather than health status with collection systems for contributions organized within industrialized setting (Abel-Smith, 1992). In some countries social insurance systems have been the forerunners of national health systems through either national insurance or tax.
The Nigerian government instituted a social health insurance system in 2005 to bring succour to the plight of its citizens through the National Health Insurance Scheme (NHIS). Health insurance involves the application of insurance principles to cover cost of defined medical benefit packages. It involves risk sharing between those who will need the benefits and those who will not. It also involves spreading the burden of cost of healthcare services to the insured over time so that the insured can access services anytime without paying.
There is dearth of literature on the effect of various health financing options for low and middle income countries (Ekman, 2007; Mills, Rasheed, Tollman, 2006). More so enrolment in insurance has been found to result in altered behavior, such as utilizing unnecessary medical care, a concept known as ‘moral hazard’ (Sulzbach, Garshong, Owusu-Banahene, 2005). Statistics form a workshop on NHIS-MDG/MCH project by NHIS between 6th -10th June, 2011 reveals that the number of enrolees registered and processed by some states in Nigeria as at March, 2011 are: Bayelsa-184,685, Gombe-161,847, Niger-162,408, Imo-90,597, Oyo-158,152, Sokoto-161,738, Katsina-80,272, Jigawa-105,739, Bauchi-158,144, Yobe-102,556, Cross River-59,910. Furthermore, evidences from countries that have institutionalized national health insurance programme indicate positive impact on the health care system (Sanusi and Awe, 2009; Collins, White, Kriss 2007). In a study in Baltimore USA, health insurance was found to lead to an increase in non urgent utilization of health facilities(Speck, Peyrot, Hsaw, 2003).Similarly in Taiwan, the utilization of most prenatal and intrapartum care services increased after commencement of NHIS(Li-Mei, Shi, Chung-Yi, 2001). Also in a related study about public insurance in North Carolina, USA, it was reported that publicly insured children were more likely to have emergency department visit than un-insured children (Luo, Liu, Frush, Hey, 2003). Same trend was also noticed in Minnesota, USA (Kane, Keckhafer, Flood, Bershadsky, Siadaty, 2002). Also in Jordan, insurance was found to have a positive effect on the utilization of curative care and significantly increased the number of visits per illness episode. (Sanusi and Awe, 2009).
Generally, insurance is found to increase the intensity of utilization and reduce out of pocket spending (Ekman ,2007). However in Nigeria, since the NHIS was established; not much has been carried out to investigate utilization and access to quality health care as a result of the introduction of the Scheme (Ibiwoye and Adeleke, 2008). In Ghana, the utilization of health facilities under insurance cover revealed that Malaria, Respiratory problems and Diarrhea were the commonest illnesses (Sulzbach, Garshong and Owusu-Banahene, 2005). In a survey in Oyo State, Nigeria, among health care consumers, 15.8% of respondents were dependants while 84.2% were workers (primary beneficiaries) (Sanusi and Awe, 2009). Pattern of utilization of general practitioners under universal health insurance in Canada indicated that females made more visits than males (Segovia, 1999).
1.2 Statement of the Problem
Nigeria’s health system is ranked 187th of 191 World Health Organisation (WHO) member states (WHO, 2000), with an infant mortality rate ranging from 500 per 100,000 in the South West geo- political zone to 800 per 100,000 infants in the North East Zone; Prenatal mortality rate of 48 per 1000 and child mortality rate of 205 per 1000. This means that over 20% of Nigerian children would not survive beyond childhood (UNICEF, 2006). More recent figures (Partnership for Maternal, Newborn and Child Health, 2008) show the North East geo-political zone attaining a mortality rate of 1700 per 100,000 births.
In most developing countries, Nigeria in particular there is a clear lack of universal coverage of health care and little equity. Access to healthcare is severely limited in Nigeria, Otuyemi, (2001). Inabilities of the consumers to pay for the services as well as the healthcare provision that is far from being equitable have been identified among other factors to impose the limitation, Sanusi, et al (2009). Financing of public health services in Nigeria has been through government subvention funded mainly from earnings from petroleum exports and user fees for patients. Decline in funding for healthcare commenced after the mid 1980’s following a drastic reduction in revenue from oil exports, mounting external debts burden, structural adjustment programme and rapid population growth rate, Shaw et al (1995). The result as in most other developing countries was a rapid decline in the quality and effectiveness of publicly provided healthcare services, Shaw, et al (1995). Funding of healthcare in Nigeria has not only affected the quality of healthcare services but led to impoverished health standard of the populace. Gana (2010), identified these funding challenges as low level of public (government) spending, high burden of healthcare costs on individuals and households (70% of all expenditure); thus ranking Nigeria as the country with the second highest level of out-of-pocket spending on health financing in the world.
More worrisome is the fact that the Nigerian System allows private healthcare providers as major stakeholders despite the establishment of the NHIS. The extent of coverage of the NHIS is such that artisans, farmers, sole proprietors of businesses, street vendors, traders and the unemployed are not yet accounted for. Even within the formal sector, not all government and corporate organisation employees are enrolled within the scheme. Our public and private hospitals therefore are still operating on a fee for service basis for the majority of its clients. Besides that, long queues are still usual sites while the issue of unavailability of required services is rearing its ugly head in NHIS approved hospitals. In addition, there is still weak and ineffective referral systems’ resulting in over burdened secondary and tertiary health facilities. Furthermore, education of the teaming populace on the pros and cons and the need to participate in the NHIS is also a challenge yet to be surmounted. In view of the aforementioned, this study seeks to assess the extent of coverage of the scheme and the degree to which the enrolees are satisfied with the Scheme in Jos.
1.3 Research Questions
- What proportion of people in Kwara is benefiting from the scheme?
- What proportion of the beneficiaries is satisfied with the scheme?
iii What are the problems and prospects of the NHIS?
1.4 Objective of the Study
The main purpose of this study is on Assessment Of Benefits And Challenges Of National Health Insurance Scheme ( Nhis) As A Tool For Achieving Universal Health Care In Kwara State Nigeria while the specific objectives include:
i.To determine the percentage of enrolees that have benefited from NHIS
ii.To determine the level of satisfaction with NHIS.
iii To exzmine the challenges facing the scheme
1.5 Research Hypotheses
Hypothesis I
Ho: The enrolees have not significantly benefited from NHIS in Kwara.
Hypothesis II
Ho: A significant percentage of the enrolees are not satisfied with NHIS in Kwara
1.6 Scope of the Study
The primary area of focus for this study will be the communities within Kwara metropolis. This will include the working populace who are adults above the age of eighteen (18) years who have enrolled into the scheme. The period under study is 2005 to 2019. The choice of this period coincides with the start of NHIS in the country.
1.7 Significance of the Study
It is hoped that this study will serve as an available reference source and will help other researchers in this field; thus contributing to the existing literature. Moreover, the study will help government and managers of the scheme in policy formulation and administration for better service delivery and improvements in the scheme.
Analysis Of Factors Affecting Employee Productivity
ABSTRACT
This study entitled ― Analysis Of Factors Affecting Employee Productivity
focused on looking at the real issues that either increase or reduce the levels of employee productivity. The study was guided by the main objective which was to determine the perceived factors that affect employee productivity. This study is anchored on three theories, namely; the goal settings theory, the systems theory and the organizations theory. The goal settings theory argued that when specific goals that are difficult to achieve are set up by the organization, it will automatically lead to high levels of employee productivity because the employees will be working hard to meet the set goals or the target. The second theory was the systems theory which argued that an organization comprised of different segment within its structures and if the organizations has to increase on its levels of production, then the various systems within the organization must have a shared vision, support each other. This will help to raise the levels of employee productivity. Finally the organizations theory argued that it‘s the organization which is responsible for shaping the attitudes and behaviors of its employees, the organization has to realign all its structures in the right manner and put in place an organizational culture that will make the employees to raise their levels of productivity. The study had a target population of 300 employees and a sample size of 150 respondent‘s .The study adopted a stratified sampling technique whereby all the employees were categorized into the existing departments at the Nigerian bottling company with its headquarters in Enugu state. Primary data was collected using the self-administered questionnaires. The questionnaire was divided into two major parts A & B where section A contained the bio data of the respondents while section B covered the statements on the perceived factors affecting employee productivity. Data was collected using the process of a drop and pick up later method. The study found out that a number of factors that affected employee productivity included the following; the style of leadership in the organization. If the leadership was progressive and acted as an inspiration to the employees, the levels of employee productivity are likely to go high. The communication systems in the organization; if the organization has got proper mechanisms that promote good communication, productivity will be high and the reverse is also true. Thirdly the proper training that the employees are taken through, performance appraisals, motivational levels of the employees, knowledge, skills and attitudes that employees have. In view of these the study recommends that the leadership of the Nigerian bottling company needs to change on its style of leadership so that it becomes responsive to the needs of the employees and inspire confidence in the employees. Secondly the study recommends that proper communication systems needs to be reorganized and strengthened so that it fosters communications in the organization both vertically and horizontally. Thirdly the study recommends that the existing policies on employee promotions at the Nigerian bottling company should be sponsored for further training either internally or in workshops, seminars and conferences so as to sharpen on their knowledge and skills and finally the study recommends a further research on the area of government employment policy in relation to the employee productivity and a similar study to be carried out on other non- governmental organizations and public organizations.\
CHAPTER ONE INTRODUCTION
Background of the Study
Stringer (2007) noted that globally organizations both public and private usually rate the levels of productivity and perceptions of their employees as a yard stick of the overall performance and progress of their institutions. This is the most reliable parameter of assessing the general performance of the organization. This parameter has been tried, tested and proven right, in that if the employees are better trained, better paid and remunerated, and constantly motivated, their perceptions would be positive and their levels of productivity will be high and the employees who are unhappy, poorly paid, poorly trained and possess negative attitude towards the organization that they work for will have negative perceptions and will do nothing other than registering a low level of productivity. This parameter has been trusted by most employers and the employees themselves. Stringer further observes that employees who are well taken care of by the organization will develop a positive attitude towards the company and they will feel empowered, recognized and encouraged. This means that they will enjoy their work unlike complacent employees who will be working because of a pay check. The levels of productivity of the former are likely to be higher than those of the latter.
This study was anchored on three theories, namely the goal setting theory, the systems theory and the organizations theory. Goal setting theory argues that when specific goals that are difficult to achieve are set up by an organization, it will automatically lead to high levels of performance because employees will be working hard to meet the set goals
or the target, however the study has noted that by the fact that an organization has set goals that are challenging. It does not automatically lead to increased productivity when it is left on its own; instead it requires the support of the levels of commitment, team work, and good working relations of employees and the employer to increase the levels of productivity. The second theory is the systems theory which advances the argument that organizations comprises of different segments within its structures, and if the organization has to increase its levels of production, then the various systems within the organization must have a shared vision, support each other, properly identifies the capability of its employees as well as working in support of each other. This therefore means that each sub-system must work hard to improve productivity, if an employee performs poorly, he will affect the entire sub-system, and finally the organizations theory argues that it‘s the organization which is responsible for shaping the attitudes and behaviors of its employees. Therefore the organization must realign all its structures in the right manner and put in place a viable organizational culture that will enable it to realize its primary goal which is to increase on its levels of productivity.
Samantha (1994) defines Employee productivity as the relationship between the output (goods and services produced) to input (consumed resources in the manufacturing, as well as the transformation process). Banolack (1997) on the other hand defines Employee productivity as how much and how well employees produce more with fewer resources. This means that if employees produce more with less resource, productivity is high or if the same products are produced with less resources productivity is also high. Weinrich & Koontz (1994) defined the term productivity to be that term that acts as a ratio between the inputs and the out puts in a specified time frame. This is done in comparison to the quality of the product. This means that in order to measure the levels of productivity, one will have to look at the extent to which the intended goals of the organization have been met and how quality standards of the expected output has been adhered to. The authors observe that the employers expect the employees to produce more output with little resources even as they maintain the levels of efficiency in production process. This author concurs with the views of Drucker (1990) who argued that the levels of employee productivity have a direct impact on the organizations overall performance. This means
that employees who are more productive will produce large quantities of output in a short period of time thereby helping the organization to save money, time and labor in the production process, unproductive employees on the other hand will take long periods of time to finish small projects. In this way costing the company more time, money, labor as well as power.
Ron and Ronald (2002) noted that the levels of employee productivity can be measured using the period of time than an employee spends at the work place. This means both physical and mental preserve. In order to ensure this, the organization must take a keen interest in an employee‘s levels of satisfaction, health status as well as levels of morale. The organization through its managers as well as the supervisors must ensure that their employees re in good status of wellbeing in order to increase on their productivity levels. Saksena (1988) observed that although it‘s difficult to measure an employee‘s levels of productivity, but its efforts will be directly felt in the overalls organizations performance. For instance, it can be easier to measure the production levels of a skilled worker than a knowledgeable worker. Ochieng (2005) suggested that productivity of the employees could be measured using variables such as cost reduction, inventory reduction, increased flexibility in operations and reduction in delivery time of goods and services, improved quality of products, services as well as increased efficiency. However the author suggests that the standardized way of measuring the output levels of both workers is to use the levels of efficiency, speed as well as occurrence of the employee in relation to his role, job and duties.
Nzuve (1992) observed that contrary to what many scholars have argued before, it is not only the salary increments, better pay or constant promotions at work that leads to the increase of employee productivity. Liberda (2003) pointed out that the style of labor management in an organization, such as poor planning; poor levels of supervision, as well as inadequate provision of relevant information to the employees will automatically lead to lower levels of employee productivity. Rojas & Aramvareekel (2003) identified four major category of factors that affects the levels of employees productivity, they include management systems and plans such as scheduling, manpower capacities, such as how experienced and motivated is the manpower, what are the working conditions that employees are subjected to, as well as the external environment that the organization operates in the authors argued that management of systems and plans is the greatest factor that affects the levels of employee productivity, they include management systems and plans such as scheduling, manpower capacities, such as how experienced and motivated is the manpower, what are the working conditions that employees are subjected to, as well as the external environment that affects the levels of employee productivity, then closely followed by manpower, working conditions as well as the external environment that a company operates in.
Other scholars such as Wanyama &Mutsotso (2010) carried out a study on the effects of capacity building on employee productivity, they discovered that there was a total clash between the employers and the employees, employees demand higher salaries and working less, while the employers are demanding
for more work and offering little salaries, besides these the scholars observed that there was poor levels of supervision, poor employee equipment was offered, lack of necessary skills and knowledge management practices, all these contributed to the low levels of productivity among the Nigerian banks, this lower productivity levels were explained through issues such as poor service delivery in the banking sector, the inefficiencies of various structures of bank, poor levels of customer relations, customer dissatisfaction as well as low levels of profits. Stevenson (2009) noted that among the factors that influence productivity levels include the amount of capital, type of technology used, management style, differences of quality of services offered, internet use, viruses affecting the computer, new workers, shortage of ICT workers and layoffs, levels of incentives and breakdown of the machines.
Research Problem
In the modern world, matters dealing with the human resource in relations to their productivity levels have continued to be a major concern of every employer, organizations as well as the governments all over the world. This is because there is the emergence of new challenges that affect the quality of the human resource and its output; therefore it‘s important for the subject employee productivity levels to be looked into with a lot of keen interest. For instance issues such as employee motivation levels, the levels of performance appraisals, management of human resource, communication systems to the human resource as well as quality of training are the leading issues as far as measurement of employee productivity is concerned. This is because depending on how an organization manages its workers concerns, its levels of productivity and overall performance will be affected in one way or the other (Delancy 1996). This view is supported by that of Knootz and Weihrich, (2004) who argued that top managers do not share all the information because they fear challenging their bases, while middle level
managers feel that they are not provided with sufficient information from top managers. In most cases they see the top managers are uninspiring, offer poor leadership and vision for the progress of the organization, the lower level managers on the other hand are either alienated or sidelined. All the above scenario leads to one major effect to the organization, that is lowering the organizations overall performance. This is because the employees are having low morale levels, uninspired hence the productivity will be very low.
The Nigerian bottling company has got slightly over 1000 workers who are spread across the country. The organization has got 300 of its employees who are based at the headquarters in 9th Mile, Enugu stateThe organization is divided into five major departments namely; Sponsorship department, Operations department, Administration and Security department, Finance and Support department, and Program development and Grants Acquisition department. Each department is headed by a director. The current status of the employee productivity at the World Vision is that the organization is not satisfied with the levels of productivity of its employees. This according to the report is among other things due to lack of proper training among the employees, refusal of some employees to work in certain areas of the country, political atmosphere in the country, lack of support from the communities in the remote areas as well as poor financial challenges which makes the organization not to be able to carry out on its daily operations. All these in one way or the other affect employee productivity
A number of studies have been carried out in the area of employee productivity. For instance Tongo (2008) did a study on causes of low productivity of workers in the Nigerian industries, the author found out that, most regular employees in the Nigerian industries felt that they are giving more to the industries than what they are getting from the industries, he found out that if the employees could be given financial incentives, such as overtime payments, salary increments as well as retirement benefits, this will go a long way in increasing their levels of productivity hence improving the overall performance of the industry. Munyao (2002) carried out a study on what needs to be done in order to increase the productivity levels of teachers in the public primary schools in Nigeria, he found out that all employees love it when they work in well performing institutions, proper HR practices such as employee satisfaction, motivation as well as constant reward will boost the levels of employee productivity.
It is therefore upon this background that this study will seek to answer the research question, what are the perceived factors that affect employee productivity in the Nigerian bottling company in Nigeria.
Research Objective
The main objective of this study was to determine the factors that affect employee productivity in the Nigerian bottling company in Nigeria.
Significance of the Study
The study will be useful to policy makers as it will greatly in form the policy making process both the finding so as well as the recommendations made by this study will be useful to the management, from the headquarters, the government of Nigeria through NGO board, the Ministry of Planning, the Ministry of Labor and human resource as well as the ministry of Interior and Co-ordination of government. These institutions will be informed of the existing challenges that employee are experiencing in as far as human resource is concerned. The suggestions made by this study on how to improve on the levels of employee productivity will be useful for them
as they design new policies. The findings of the study will also be useful to other NGOs in the private sector, this is because, not only will it give them insights on how to prepare, review and improve on the working conditions of their employees, but will seek to devise new ways of how to ensure an increment in employee productivity.
Secondly, the study will serve to identify the weaknesses of the three theories that have been used to anchor the study on; these theories include the goal setting theory, the systems theory as the organizations theory. Not only will the study put the relevance of the three theories into a practical test, but will also serve to strengthen them in that the weaknesses of the goal setting theory such as an organization setting difficult goals for its employees to achieve, but at the same time failing to ensure that the employees remain committed to the goal, and stay motivated even as they strive to meet the set targets, among other weaknesses are addressed. The improved theories will be in a better capacity to fulfill its core functions of describing a phenomenon, explaining a phenomenon, predicting a phenomenon as well as prescribing a phenomenon. This will be useful to the academicians in future and form a basis for further research and a platform of Academic debates.
Finally, the study will also be useful in the field of Human Resource Management and HR practice. This is so because all the Human Resource Managers will be greatly informed of the modern challenges that affect the levels of employee productivity in all the organizations globally. The HR managers and practitioners will be very keen when designing of job advertisements, preparing of job descriptions, and the recruitment of
new staff. They will be keen in going for those personal attributes that will enable the employee have high levels of productivity. Besides these the findings of the study as well as the conclusion and recommendations made will be useful in expanding the existing knowledge of HR practice, not only will it offer constructive criticism to the existing theories of employee productivity but it will offer suggestions on how the theories can be improved in order to ensure that they adequately describe, explain, predict and prescribe all the matters dealing with employee productivity.
