PSYCHODYNAMIC PERSPECTIVES ON ADULT LEARNING GROUPS

The purpose of this paper is to stimulate thinking among adult educators about how unconscious factors and a participant’s internal world influence the adult learning group. The paper includes excerpts from conversations and interviews with three participants of the same learning group. A psychodynamic perspective was used to understand how the group process affected the learning of these three group participants. The use of a psychodynamic orientation includes the belief that the unique reality of each group member is influenced by temperament, life experience, family of origin, and unconscious processes. Despite the challenges and the seriousness of questions that have been raised by critics of psychoanalysis, it offers a way to look at adult learning which considers multiple perspectives and it recognizes areas that are beyond our conscious awareness yet affect our behavior and learning

ORGANIZATIONAL CULTURE VARIABLES AS FACTORS INFLUENCING LIBRARIANS’ TURNOVER INTENTIONS IN UNIVERSITY LIBRARIES IN SOUTH-SOUTH AND SOUTH-EAST OF NIGERIA

The study investigates organizational culture variables as factors influencing librarians’ turnover intentions in university libraries in South-South and South-East of Nigeria. The study adopted a descriptive survey research design. Total enumeration method was used since the population comprising 400 academic librarians in the two geopolitical zones were considered appropriate for the study. A test-retest of the measuring instrument was done using Cronbach’s alpha reliability coefficient and face validity. The result of the reliability test was 0.85 at 0.05 level of confidence. From the total copies of questionnaire that were administered and retrieved, 334 were found usable given a return rate of 83.5%. Results were analysed using percentage, mean and standard deviation. The result revealed that imbibing positive organizational culture in the university libraries in the areas of training, promotion, payment of salaries and rewarding deserving librarians have the potential of reducing turnover intentions. This study further showed a relationship between organizational culture and turnover intentions of librarians in university libraries in South-South and South-East of Nigeria (R = 0.-344, p \u3c 0.05), which means that the higher the level of organizational culture, the lower the level of turnover intentions of academic librarians in South-South and South-East of Nigeria. The study concludes that turnover intention of librarians is a trend that needs some determining effort and measure to curb it. Since employees’ engagement level is likely to be affected by unfavourable organizational culture, their welfare should be paramount. Libraries should formulate policies and culture that are inclusive of training, promotion, payment of salaries and rewarding of librarians to reduce turnover intentions

Hot section components life usage analyses for industrial gas turbines

Industrial gas turbines generally operate at a bit stable power levels and the hot section critical components, especially high pressure turbine blades are prone to failure due to creep. In some cases, plants are frequently shut down, thus, in addition to creep low cycle fatigue failure equally sets in. Avoiding failure calls for proper monitoring of how the lives of these components are being consumed. Efforts are thus being made to estimate the life of the critical components of the gas turbine, but, the accuracy of the life prediction methods employed has been an issue. In view of the above observations, in this research, a platform has been developed to simultaneously examine engine life consumption due to creep, fatigue and creep-fatigue interaction exploiting relative life analysis where the engine life calculated is compared to a reference life in each failure mode. The results obtained are life analysis factors which indicate how well the engine is being operated. The Larson-Miller Parameter method is used for the creep life consumption analysis, the modified universal slopes method is applied in the low cycle fatigue life estimation while Taira's linear accumulation method is adopted for creep-fatigue interaction life calculation. Fatigue cycles counting model is developed to estimate the fatigue cycles accumulated in any period of engine operation. Blade thermal and stress models are developed together with a data acquisition and pre-processing module to make the life calculations possible. The developed models and the life analysis algorithms are implemented in PYTHIA, Cranfield University's in-house gas turbine performance and diagnostics software to ensure that reliable simulation results are obtained for life analysis. The developed life analysis techniques are applied to several months of real engine operation data, using LM2500+ engine operated by Manx Utilities at the Isle of Man to test the applicability and the feasibility of the methods. The developed algorithms provide quick evaluation and tracking of engine life. The lifing algorithms developed in this research could be applied to different engines. The relative influences of different factors affecting engine life consumption were investigated by considering each effect on engine life consumtion at different engine operation conditions and it was observed that shaft power level has significant impact on engine life consumption while compressor degradation has more impact on engine life consumption than high pressure turbine degradation. The lifing methodologies developed in this work will help engine operators in their engine conditions monitoring and condition-based maintenance

Petroleum activities, wetland utilization and livelihood changes in Southern Akwa Ibom State, Nigeria: 2003-2015

The state of Akwa Ibom, Nigeria is known as one of the wetlands rich in biodiversity as well as oil and gas reserves. Its wetland ecosystem is noted for its primary support it has provided for the people living in this area. However, this wetland has also been a reservoir for Nigeria’s crude oil contributing a prominent share of petroleum product to the country’s GDP, total revenue to the government through exports and other fiscal surpluses, making it Africa’s largest economy. But back home where the resources is harnessed to achieved and attained the height of this economic successes the situation is a direct contrast, petroleum activities is mostly synonymous to environmental pollution, degradation, conflicts and crises. Wetland is not left out of these adverse effects. Therefore this study was based on the impact of petroleum activities and its effects on wetland, agricultural practices within the wetland, people’s livelihood as well as strategies for sustainable management of wetland in the study area. GIS and Remote Sensing was used, by adding ancillary data from ground truth points and other reference sources to the thematic LULC satellite images of the study area. Erdas Imagine and ArcMap were used in processing, monitoring and mapping the wetland changes caused by petroleum activities and the consequent effects of these actions by assessing the pattern of distribution of the affected wetland, taking into consideration the baseline data such as vegetation types, densities, phenology, as well as land use cover types. Livelihood changes were measured by conducting interviews to different stakeholders in the course of this research. The result showed that there has been a significant change in the wetland area of Southern Akwa Ibom State though more than 68% of the wetland mapped had not changed. While wetland was increasing in some areas others experienced a decrease. Livelihood changes in the area shows that petroleum activities have benefited the people in areas of employments both directly and indirectly although they are still expecting an improvement in areas such as provision of farm inputs, health and housing facilities from the Multinational Oil Companies. It was observed that management of the wetland was majorly based on traditional methods of total and periodic restrictions to some community preserved areas as well as periodic fallowing. The traditional management strategies of seasonal restrictions and buffers is not sustainable enough to protect and preserved the wetlands from complete degradation and as such measures should be taken to sensitize all stakeholders in the study area to adhere to the government laid down laws and regulations in order to protect, preserve and ensure a sustainable wetland for future generations.Nigeria’s Akwa Ibom State is a region that is naturally endowed with rich wetlands containing abundance of oil and gas deposits. These wetlands have been a source of primary support for the inhabitants of the area. It also forms one of Nigeria’s crude oil bases that contribute immensely to the vast petroleum product of the country. Nigeria has an increased revenue base due to production and exports of this crude oil making her the leading and largest economy in Africa. With this gigantic economic achievement one would expect that these successes be translated into the betterment of the generality of the people as well as the sustainability of the environment where these activities are carried out. Rather, petroleum activities in the region have led to environmental pollution, degradation, conflicts and crises within the host communities. Wetland is one of the major ecosystems polluted and degraded by petroleum activities in the region. Therefore, this study was based on the impact of petroleum activities and how it affects the wetlands, the agricultural practices within the wetlands and the people’s livelihood within this region. It also assessed the strategies used for sustainable management of wetlands within the area. The methods used in the study were mainly Geographic Information System (GIS) which enabled the collection and processing of geographic data and Remote Sensing (RS) which provides information on geographic objects using satellite or airborne platforms. Primary and secondary sources such as using Global Positioning System (GPS) receiver which provides information on spatial data position was used to collect ground truth sample points. Thematic Land Use Land Cover satellite images of the study area as well as other relevant reference materials were also acquired. GIS and Remote Sensing software like Erdas Imagine and ArcMap were used in processing, monitoring and mapping the wetland changes caused by petroleum activities and the consequent effects of these actions, by assessing the pattern of distribution of the affected wetland, taking into consideration the baseline data such as vegetation types, densities, phenology, as well as land use cover types. On the measurement of livelihood changes, interviews were conducted across the different stakeholders within the study. The result showed that there has been a significant change in the wetland area of Southern Akwa Ibom State though more than 68% of the wetland mapped had not changed. While wetland was increasing in some areas others experienced a decrease. Livelihood changes in the area shows that petroleum activities have benefited the people in areas of employments both directly and indirectly although they are still expecting an improvement in areas such as provision of farm inputs, health and housing facilities from the Multinational Oil Companies.
