Environmental Uncertainty and Entrepreneurial Success (Published)

This study aims to examine the effect of environmental uncertainty on entrepreneurial success amongst 9,450 small and medium enterprises (SMEs) who are registered members of the National Association of Small and Medium Enterprises (NASME), National Association of Small Scale Industrialists (NASSI) and Association of Small Business Owners in Nigeria (ASBON) in Lagos State. Proportionate stratified random sampling method was used to select samples from the sampling frame. Sample size of 381 used for the study was determined using the formula developed by the National Education Association (1960). Primary data on the dependent variable (Entrepreneurial success) and independent variable (Environmental uncertainty) was collected using questionnaire as research instrument. Environmental uncertainty measures are dynamism, complexity and hostility while measures for entrepreneurial success are profitability, market share, net asset growth, sales growth and government policies. The questionnaire was pretested by a pilot study of 50 selected SMEs. Data obtained from the pilot study was analyzed and based on the result, the questionnaire was slightly modified giving an overall Cronbach’s Alpha value of 0.791. The statistics of the model summary reveal correlation co-efficient R = .519 indicating that the combined influence of the three predictor variables of dynamism, complexity and hostility has a strong positive relationship with entrepreneurial success. The R square is .269 or 26.9% signifying that the combined influence of the predictor variables explains 26.9% of the variations in entrepreneurial success. The value of F (3,206) = 25.321, p <.05, shows that the combined effect of dynamism, complexity and hostility was statistically significant in explaining changes in entrepreneurial success in Lagos State. This is confirmed by a p value which is less than the acceptance critical value of 0.05. The model shows that the regression coefficients results for both dynamism (β = .155, t = 2.390, p = .018) and complexity (β = .464, t = 7.392, p = .000) indicate positive and significant relationship with entrepreneurial success in Lagos State. The finding indicates that a unit increase in both dynamism and complexity of environmental uncertainty would lead to increase in entrepreneurial success in Lagos State. The regression coefficients for hostility (β = -.155, t = -2.484, p = .014) indicate a negative relationship with entrepreneurial success, though the relationship was significant, p <.05. Complexity measure has the highest influence on entrepreneurial success with a p value was 0.000 followed by hostility with a p value 0.014, and then dynamism with a p value of 0.018.

The Decision Constraints in Construction Project Scheduling Using the Ms Project Planner (Published)

This paper reports a library research which investigated the way decisions of early start or late start schedules are applied in the MS Project. The problem intended to solve or clarify is whether literature holds the scenarios where options of early or late start schedules may show superior schedule performance. It is noted that key scheduling processes and procedures such as choice of early start schedule and late start schedule will significantly impact project performance. This literature search proposed answer to the question: How can the planner make better scheduling decisions and explore relative benefits of alternative options? It shows that project performance evaluation results may provide evidence that some choice influence schedule variability which in turn, is strongly and positively correlated to productivity. It is imperative for contractors to continually monitor the scheduling practices adopted, the choice made when the schedule is developed and relate these to project performance in order to identify particularly effective scheduling practices for use in scheduling future projects. Strong argument is developed from literature that if network scheduling methods fail to address the issue of start time constraints for various project tasks, it is likely that the schedules generated will be inaccurate. This is because changes in the schedule are inevitable occurrences in construction projects. The causes of such changes are numerous and well catalogued in the literature: weather, owner-directed changes, information request and information release problems, period for approval of submittals, unexpected soil conditions, long lead supply items, delays, accelerations, and rework that affects schedule coordination difficulties. Such changes are challenging and difficult to proactively accommodate in the initial schedule development because they affect multiple activities, often leading to disruption of activity start dates of succeeding tasks. It is therefore important to satisfy practical scheduling requirements, such as scheduling an activity to start only when all information requests, all prerequisite work and materials required for its commencement are available. The paper concludes that a good understanding of the tasks affected by these listed delay causes is important so that a right choice of start date is made to proactively nip the delay situation at the bud. If disruption of activity start is reduced to zero particularly for the critical activities, then the project may finish on the due date, with optimum overall project cost.

Multiple Prediction of Research Productivity: H-Index (Published)

Research Productivity, h-index, of faculty is predicted on their job-satisfaction, persistence, optimism, self-discipline, motivation, and procrastination. Never has been a better answer than H-Index in the history of science to the question of how to quantify the cumulative productivity, accomplishments, impact, and relevance of a researcher’s scientific work. Multiple Prediction design of correlational research method was adopted in the investigation. Faculty in natural sciences in universities around the world constituted the population. A multistage random sample of 180 faculty, 30 from each continent 7 or 8 from each of 24 universities, and 4 universities from each of 6 continents made the sample. Results showed statistically significant 21 correlation coefficients among the seven variables. The six independent variables taken together, significantly predicted research productivity [F (6,   173) = 72.379, p < .01, R2 = .715]. Each of persistence, optimism, self-discipline, and procrastination unilaterally predicted research productivity significantly. Neither job-satisfaction nor motivation singlehandedly predicted research productivity. Multiple regression equation was created for the prediction of research productivity from the six independent variables. Predicted values and residuals for each participant were tabulated.

Discovering Consumer Intentions toward the Adoption of Cloud Computing In Higher Education Institutions in Kuwait (Published)

Cloud computing has grown immensely over the past few years in the Information Technology field. Optimism for supplier of cloud service and the possible risks associated with privacy and security of users is essential factors for implementation of successful and suitable cloud. Therefore, the main challenge of cloud computing is it’s perceptual and approaches. This research focuses on Technology Acceptance Model (TAM), which mixes Anxiety, Optimism and Risk, to study student’s attitude and behavior toward the implementation of cloud service. The planned model was studied using the Structure Equation Model (SEM) to examine data collected by a survey of both IT experts and users. The analysis showed that three variables of Optimism, Innovativeness and perceived risk can be positively combined within the Technology Acceptance Model (TAM). Innovativeness were suggested to have significant positive influence on the Perceived Ease of Use (PEOU) and Perceived Usefulness (PU). On the other hand, Optimism has positive impact on the PEOU, but had no influence on PU. Moreover, Behavioral Intention is predictable by Optimism, attitude and PU. Students behavior and intentions is explainable through PR, Optimism, and Innovativeness in the projected model in Kuwait.

Association between Optimism, Dietary Habits, Lifestyle and General Health Self-Assessment: A Pilot Study (Published)

The aim of the study was to develop and standardize a new questionnaire to examine the relationship between optimism, dietary habits, lifestyle and general health self-assessment. A pilot study was conducted in a sample of 114 individuals of general population in Sparti/Greece. The questionnaire combines a general health self-assessment questionnaire (GHSAQ), the GrLOT-R, the weekly dietary habits, a personal/family medical history and a lifestyle questionnaire. The mean score of GrLOT-R and GHSAQ was found equal to 20.209(±3.817) and 27.482(±4.164) respectively. Higher score on GHSAQ was associated with the frequency of consumption of kiwi (p=0.027), orange (p=0.022), green tea (p=0.044) and raw olive oil (p=0.044). Higher score in GrLOT-R was associated with the frequency of consumption of fruits (p=0.028), pepper (p=0.037), red cabbage (p=0.011) and carrot (p=0.023). GHSAQ and GrLOT-R have acceptable internal validity (Cronbach’s α=0.719 and 0.723 respectively) and a very high Test-Retest reliability (Pearson’s r=0.928 and ICC=0.962 for GHSAQ and Pearson’s r=0.950 and ICC=0.983 for GrLOT-R). The new questionnaire is reliable and valid. High vitamins, antioxidants intake and water consumption seem to influence positively optimism and general health self-assessment
