Human-made cataclysmic events from over 50 years of oil production, gas explosions, and oil spillages soak the Niger Delta pose psychological challenges to the people in the environment. Thus this study examined environmental worry of Rivers State residents of Niger Delta, Nigeria. Data collected were analysed using independent t-test and one-way ANOVA. The findings of the FGD revealed that there is an awareness of loss of land, loss of control of technical networks in oil production and experience of environmental degradation. Additionally, the survey results showed a significant difference on environmental worry based on sex and age. However, nativity, employment status and educational status did not significantly differentiate between groups on environmental worry. The implication of the results of the study is discussed in line with relevance of residents' expectations, prospects and choice of enduring lifestyle, living and survival.

The labour-management relationship is often referred to as a natural adversary relationship, a disconnect, grounded in conflict. This study therefore examined the contribution of staff job satisfaction to their level of job involvement in a private institution. This study adopted a survey research design. One hundred and fifty (150) participants randomly selected completed the psychological tests. Multiple regression was used to analyse the data collected. The result showed that job satisfaction and demographic factors jointly predicted sixty four percent (64%) significant variance on job involvement. There is significant independent prediction of job involvement by age, job satisfaction and some characteristics which are supervision, fringe benefit, contingent reward, operating procedure, coworkers and communication. The implications of the result were discussed in line with corporate governance and conflict resolution.

Several studies extended the Technology Acceptance Model (TAM) by examining the antecedents of perceived usefulness and perceived ease of use; the present study looks at demographic aspect of external variables in virtual library use among undergraduate students. The purpose of this study is to identify the demographic factors sex, level of study, cumulative grade point average, and computer knowledge that act as external factors that are antecedents of perceived usefulness and perceived ease of use. The university management makes a large investment in the provision of a virtual library; investigation of the virtual library acceptance by students is important. TAM and theory of reasoned action (TRA) are utilised to theoretically test a model for the extension and to predict virtual library acceptance and usage. In a survey study, data was collected by using a structured questionnaire given to 394 randomly selected participants in a private university. Data were analysed by Pearson product moment correlation, multiple and hierarchical regression. The result of the study is consistent with TAM factors examined for explaining virtual library usage. The extension model accounts for 2.5% variance in perceived usefulness, 2.1% in perceived ease of use, 11.7% -15.2% on intention to use and 7.2% on actual use of virtual library. Implications of the findings of the study on user's virtual library training are discussed.

Many studies have been done on human-computer interaction (HCI), but there is a dearth of studies on the mandatory actual system use in Nigerian university libraries. The relationship between sources of computer self-efficacy and outcome expectancy on actual system use was assessed, based on social cognitive theory, by surveying mandatory use of KOHA version 3.0.1 integrated library management software. The questionnaire survey was conducted on 61 library personnel in 5 private Nigerian universities. Data were analyzed by multiple regression analysis and Pearson product moment correlation. The structural model accounted for 48% of variance in actual system use, 80% in computer self-efficacy, and 19% in outcome expectancy. This study suggests that usability, supportive management, and computer self-efficacy are important determinants of actual system use of KOHA software. Self-efficacy had influence on outcome expectancy. The implication of applying the social cognitive theory to actual system use of KOHA software by library personnel is discussed.
