This paper discusses the perception of gravel suppliers in the six states situated in South-western Nigeria. It reported findings from a research on gravel supply studies in the study area. Major gravel pits, together with their perceived technical characteristics in the states were identified through a structured questionnaire designed to solicit response from truck drivers and association of gravel suppliers. Based on this, factors affecting gravel supply and usage were measured by random variables devised for the purpose. The observed outcomes of the variables from the survey carried out constituted the research data. The collated data was analyzed based on quantitative method through the use of simple percentage method of data analysis. The paper posits that geological location of Lagos state is responsible for the absence of any gravel pit in the state, hence the prohibitive cost of gravel in the state when compared to other states in the zone. In all the states, more than 99% of gravel suppliers attribute transport as a major factor affecting the cost of gravels. The technical characteristics of gravels from South-western Nigeria are also perceived to be good in construction, though these assertions need to be empirically proved.

This study analyzed the profitability of ginger value addition in Abia State, Nigeria. This study identified the ginger value-added products common in the area, the cost implications of the value addition process, and the socio-economic and farm-specific factors affecting ginger value addition. A stratified random sampling technique was used to select 60 (sixty) respondents and a well-structured questionnaire was used to collect the necessary data. The results revealed that the value ginger products were dried ginger, salted ginger, ginger flakes, ginger oil, and ginger paste. The factors affecting the profitability of ginger value addition from the linear regression model shows that education, income, capital, and collateral were significant. It is, therefore, recommended that youth and entrepreneurs should invest in ginger value addition as it is profitable and it is a sure way to economic empowerment and fight against hunger.

Purpose of the study: The objectives of the study were to critically analyse and explore the factors affecting job-search behaviour and to analyse the effect of such factors on job-search behaviour. Design/Methodology: 145 samples were obtained using a well-structured questionnaire from the population of 677 graduated students from Sohar University, using convenience sampling technique and the data collected was analysed using Statistical Package for Social Sciences (SPSS). Findings: The results of the study revealed that most of the graduated students do not have a clear method to apply for a future job whereas they believe that the internet is the best way to find a job and the degree they possess will help them to find a job in the field of their expertise. It was also revealed that they were confident that they have gained sufficient knowledge and skills required from the university and they prefer to have a clear plan to find a job. Research Implications: It was suggested that the Government should create jobs based on skills and open channels to recruit skilled graduates. It was also suggested that the Higher Education Institutions (HEIs) should try to alter the curriculum and introduce professional/technical courses eliminating the gap between the HEIs and the labour market. Practical Implications: The study will help the colleges and the universities in conducting workshops and the related activities in engaging students towards increasing their skills. Originality: No study was carried out before to study the job-search behaviour of Omani students and this is a study of its own kind.

Restoration Cost

Purpose – The purpose of this paper is to identify the most influential buildings elements in term of the cost for timber restoration works. Design/methodology/approach – The research employed the case studies methods with questionnaires surveys. Two case studies were chosen and questionnaire surveys were distributed to contractors and consultation companies. The cost was identified based on the elemental cost analysis of historic timber buildings. Findings – The restoration of historic timber buildings in Malaysia has grown rapidly, especially in the UNESCO world heritage sites, Melaka and Penang. Data obtained on the restorations of timber buildings show that the most influential elements were upper floors, roofs and walls. Termites’ invasions and the lack of building analysis were found to be the major issue in timber restoration works. In addition, the availability of timber material contributed significantly to the increase of cost for restoration works. Originality/value – The cost for every element was identified and was used as a reference for new restorations projects of historical, timber buildings. This paper also highlighted the causes for the problems and the factors affecting the cost of timber restoration works. These data are useful information, especially for surveyors and contractors who are involved in the restoration of historic timber buildings. Maintaining or replacing these elements with other material can help to minimise the restoration cost of timber buildings in Malaysia.

(1) Introduction: Poor uptake of referral for ear and hearing services in Malawi has been demonstrated in previous research. A multi-component educational intervention was developed to address poor uptake. The aim of this study was to explore the feasibility and acceptability of the intervention. In addition, we aimed to provide a case study of an intervention development and feasibility testing process in preparation for a potential randomised trial. (2) Methods: The intervention included three components: (i) an information booklet; (ii) personalised counselling by a community health worker and an expert mother; (iii) a text message reminder. To assess feasibility, the counselling and information booklet were provided for caregivers of eligible children (<18 years) at ear and hearing outreach camps in Thyolo. Text message reminders were sent to caregivers after the camps. After 4 weeks, all caregivers were revisited and completed a structured questionnaire and a subset were interviewed in-depth. (3) Results: 30 children were recruited, and 53% took up the referral. Interviews found counselling with a booklet was acceptable. It provided motivation, enabled a two-way conversation, and helped dispel fear. It allowed information to be shared with social networks, initiating conversations about raising funds. The text message reminder was reported to be a valued prompt. Challenges to feasibility included low network coverage, and time needed for counselling. Residual barriers included the costs of transportation. The cost was £3.70/camp. (4) Conclusions: The study found that counselling with an information booklet was feasible and acceptable. The process of testing the feasibility of the intervention identified some adaptations to the intervention components and delivery which could be implemented before it is tested in a trial. This study highlighted the value of the feasibility testing process.

The Cost

Actual cost in construction projects has tended to exceed the project budgets. Thus, cost contingency from the initial of the project is the significant budget to complete project activities. Cost contingency is an important element of  cost estimation to protect project stakeholders such as owners, contractors, and architects from the risks of the project. This paper reviewed the previous studies to find the factors affecting cost contingency and proposed a regression model to predict the cost contingency for private projects in Vietnam. Through industry survey, project performance information from a total of 48 private projects in Vietnam was gathered. The research also compared with other studies to have an overview about cost contingency predicting methods. The key benefit of this research is that the project managers can use this model as another forecasting method to get a better quality cost management. The further research can be focused on developing the model for other project types in Vietnam.

The Impact

The cardinal objective of this study is to examine the impact of Land Title Document on credit access and business growth.  A case study was applied on Nasarawa state, Nigeria to better understand the phenomenon been researched. Information was gathered from the field through face-to-face interviews and through the administering of questionnaire among business operators in some selected towns. The research revealed that a large proportion of respondents do not have Land Title Document to their business premises and that they have never made a request for it from government agency before. 60.00% of respondents’ responded that the duration of the processing of the document takes months/years.  44.52% of respondents reported that never have banks made request for  the document before granting loan facilities while  30.24%  of respondents’ indicated ‘yes, often’. From the responses, 40.47% of respondents were of the view that possession of ‘C of O’ document will not enhance their capital based and business expansion. The views of the respondents suggest that delay is a major problem in the processing of Land Title Document. Among the reasons cited for the delays are problems with documentation and legal issues. A reasonable percentage of respondents (31.43%) were of the view that the cost of obtaining ‘C of C’ is high and difficult in the State. A suggested solution is that the government agency handling this document should be reorganize and the steps required to obtain this document should be reduced and made uniform within the State.

The usual objective when drilling a well is to drill for the lowest overall cost. At first sight, this may seem like a requirement to drill as fast as possible, since many of the costs, such as the rig day rate, wages etc., are time dependent. However, some costs are fixed, for example the cost of the bit, and it may not always be economic to pay a very high cost for a bit that drills somewhat faster, particularly if the other costs are low.In this paper, some first 3465 feet of a reservoir lithology including four bit runs are analyzed so that factors affecting penetration rate are optimized and the lowest possible well cost is achieved. The effects of using other bit types, WOB, RPM and bit hydraulics are simulated in an attempt to determine the optimized parameters, which result in the lowest drilling cost. In this study, reducing both nozzle sizes and mud flow rate, the horse power dissipated at the bit is increased, hence reducing cost per foot of drilled interval. As it is noted, by using this simulator, 17% of the original well cost is saved, which is a considerable amount of money.
