To examine how psychological diversity among work team members affects team interaction processes. Psychological diversity is described in terms of personality attributes (emotional stability, extraversion, conscientiousness, openness to experience, and agreeableness), need for achievement (nAch), and emotional intelligence. Team interaction processes include workload sharing, team communication, member flexibility, social cohesion, team viability.

A survey research was conducted that involved 1,421 oil‐drilling workers in 54 work teams. The participants were drawn from five major oil drilling companies in Nigeria. Standardized measures were used to collect data on each of the variables examined.

It was found that each of the measures of team interaction processes is predicted by different psychological diversity measures. However, emotional stability, extraversion, agreeableness and emotional intelligence are significant in predicting overall team interaction processes.

The psychological diversity measures examined are not exhaustive. It is also not clear the extent to which the findings can be generalized to other work settings that are different from oil‐drilling companies.

Human resources management in organizations that work in teams needs to include in their selection programs, psychological measures for identifying applicants who possess requisite psychological features for team work.

Study of the efficacy of psychological variables in enhancing work teams in oil drilling firms in Nigeria.

There is a growing mismatch between the skill demands of the industry and the offerings of academia. One way of reducing this mismatch is by improving collaborations between practitioners and instructors using web-networking platforms. However, it is important to understand practitioners’ considerations while collaborating with instructors. Therefore, this study identified these considerations in order to infer inputs for the design of the graphical user interface (GUI) of a web-based platform for connecting instructors and practitioners.

A mixed method was adopted through a survey and focus group. A survey was used to capture practitioners’ considerations while collaborating with instructors for student development, and a focus group helped uncover an in-depth understanding of the study phenomena. The data were analyzed using descriptive and inferential statistics and thematic analysis.

The results show the willingness of practitioners to collaborate with instructors for student development, the ways by which practitioners are willing to meet instructors' course-support needs and their considerations in deciding to do so. Slight differences were observed between the results of the survey and the focus group regarding the ranking of the practitioners’ considerations. The study highlighted demographic differences in practitioners’ considerations when deciding on meeting instructors' course-support needs. The results provide a basis to deduce the GUI inputs of web-networking platforms for connecting instructors and practitioners.

This study revealed practitioners’ design needs and GUI inputs to facilitate the design of web-networking platforms for connecting instructors and practitioners. This study also contributes to user interface design principles, theories on individual differences and practitioners’ involvement in student professional development.

The objective of this study is to develop two nutrient‐dense and acceptable weaning foods – Prowena and Propalm – using high‐protein food ingredients: crayfish (Macrobachium spp), soybeans (Glycine max) and groundnut (Arachis hypogea) to enrich the sole starch based weaning food locally known as “ogi”.

The weaning food mixture was formulated by mixing yellow maize ogi flour, soyflour, groundnut meal and crayfish flour for Prowena (PROW) while palm oil was added to the mixture for Propalm (PROP). PROW and PROP were compared with the commercial weaning food Nutrend (NUTR) and the traditional weaning food, yellow maize gruel, or ogi (YOG), in terms of energy, nutrients and sensory scores.

Chemical analysis showed that PROW contained 2.71 per cent moisture, 22.95 per cent protein, 5.86 per cent fat, 3.75 per cent fibre, 62.39 per cent carbohydrate, 4.31 per cent ash and 3.75 kcal of energy, while PROP had 2.78 per cent moisture, 21.99 per cent protein, 8.86 per cent fat, 3.89 per cent fibre, 59.29 per cent carbohydrate, 4.77 per cent per cent ash and 3.78 kcal of energy. The sensory evaluation showed that both PROW and PROP were equally acceptable as NUTR and more acceptable than YOG in terms of taste, flavour and texture (p<0.05). However, there was no significance difference (p>0.05) in acceptability of PROW, PROP, NUTR and YOG in terms of colour.

The paper shows that the two weaning foods would be suitable for the commercial market to increase the protein intake and to combat protein energy malnutrition (PEM) amongst infants.

To examine how personality dispositions of Nigerian politicians predict their attitude to the wellbeing of citizens.

A survey research was embarked that engaged 185 political aspirants to various electoral positions in the 2003 Nigerian elections. Respondents were administered a standardized psychological instrument that measures four personality attributes – needs for achievement, affiliation, dominance, and autonomy. They also responded to another standardized instrument that measures attitude to wellbeing of people.

Hierarchical multiple regression analyses conducted showed that gender and age are significant predictors of politicians' attitudes to wellbeing of the people. Male and younger politicians are more favorably disposed to people's wellbeing than female and older politicians. Among the personality attributes only need for achievement significantly accounted for variations in attitude to people's wellbeing. Specifically, the lower politicians are in need of achievement the more favorably disposed they are to people's wellbeing.

The research participants are not completely representative of politicians in Nigeria because the sample was drawn from the Southwest only. In addition, the personality attributes examined are not exhaustive as there are other possible attributes that could predict politicians' attitudes to citizens' wellbeing. There is also a limit to which results on attitude can be used to predict actual behavior of politicians to people's wellbeing.

The study demonstrates the need for psychological tests in Nigeria's electoral process. It demonstrates that personality attributes of politicians could be assessed and used to predict their concern for citizens' wellbeing. It is opined that, where politicians are more concerned with the citizens' wellbeing, it could enhance the sustainability of democracy in Nigeria.

The paper demonstrates a dimension of psychological testing in Nigeria's electoral process.

This study examined factors influencing the organisational capabilities of the public sector for building information modelling (BIM) implementation in construction projects with a view to enhancing the performance of public sector projects.

The study adopted a quantitative descriptive analysis that was based on primary data. In total, 198 valid questionnaires obtained from construction professionals within the public sector provided primary quantitative data for the assessment. The respondents provided the responses on the factors which were identified through an in-depth synthesis of literature relating to organisational capabilities of the public sector. Data collected were analysed using descriptive and inferential statistics.

The findings established that the potential of the public sector to deploy BIM in construction projects is greatly influenced by varying degree of organisational capability attributes with bureaucratic culture (mean score, MS = 3.37), structural complexity (MS = 3.17), lack of skilled and trained staff (MS = 3.12), personnel stability (MS = 3.11), staff cooperation (MS = 3.09) and political constraint (MS = 3.07) ranked highest. Through factor analysis, these and other highly influential factors were grouped into eight components, namely management-related, policy-related, technical-related, attitude-related, work structure-related, work ethic-related, decision-related and feedback-related factors. This grouping reflects the various components of organisational capability attributes which the public sector needs to efficiently develop to benefit from project management paradigm introduced by BIM.

This study provided information for improving specific capability attributes with respect to human and technical resources as well as other soft infrastructure to support BIM implementation on building projects by the public sector client. The study also serves as a guide for understanding BIM implementation by the public sector in similar socio-political and economic contexts.

This assessment indicates various degrees by which the organisational attributes of public sector have influenced the attributes' capability to implement BIM on construction projects. Thus, findings provide information on areas of improvement for better implementation of BIM by the public sector in project delivery.

The purpose of this paper is to examine the challenges of accountability and development in Nigeria. In the literature, corruption is seen as an indicator of a lack of political accountability in most countries of the world, especially in less developed countries such as Nigeria. The Nigerian Government has taken several actions to address the problems of bad governance and corruption that have impeded economic development, but unfortunately these measures have not yielded the desired results.

Thus, this study examined accountability and developmental issues in Nigeria using secondary data and then made use of the auto-regressive distributed lag econometric technique to analyze the data.

The results from the study found that a rise in total government expenditure poses a danger of reducing Nigeria’s economic development in the long run and that control of corruption and political (the institutional variables) has a direct and significant effect on Nigeria’s economic development.

Therefore, upon these findings, this paper recommended that for Nigeria to experience development, corruption should be eliminated, and the Nigerian Government should spend on viable projects and economic activities that will be beneficial to the populace and the society at large and hence bring about economic development. Accountability is the hallmark of a prudent government that ensures efficient management of resources and transparency in the utilization of funds by the government. The absence of accountability mechanism allows corruption to thrive, which hinders the developmental process.
