Adolescents' sense of identity is therefore, largely unexplored research domain that could benefit from greater attention. This study utilized correlational survey design to examine the pattern of relationship between self-efficacy, parental supports, peer influence, internet usage and sense of identity among adolescents. Two hundred and sixty students (Male=121; Female=139) between 15-18years (x=13.05; SD=14.2) were drawn from secondary schools in Nnewi, Anambra State using simple random sampling technique in four stages. Five standardized self-report questionnaires namely; Serafini and Adams Sense of Identity scale (r=0.78); Jerusalem and Schwarzer General Self Efficacy measure (r=0.76); Pasquali and Araujo Parental Perception Questionnaire (r=0.077); Steinberg and Monahan Resistance to Peer Influence scale (r=0.74) and Young Internet Addiction Test (r=0.79) were used for data collection. Pearson Product Moment correlation result show that while adolescent sense of identity has negative relationship with self-efficacy (r = -.441; p<.05) positive relationship exist with peer influence (r =.253; p<.05). There was no significant relationship with parental supports and internet usage on sense of identity. Multiple regressions analysis revealed that the independent variables contributed 21.0% of the variance in adolescents' sense of identity. Self-efficacy made the most potent (=-409; t (258) =-.6963; P<0.05) contribution in predicting sense of identity. The researcher concluded that for education to contribute significantly towards making the world safer there is urgent need to incorporate enhancement of self efficacy into educational and counselling interventions for in-school adolescents. 1 results 1
- A survey was carried out to assess the methods of livestock and poultry wastes management in Swaziland. The survey adopted the use of questionnaires which sought for information on the types of wastes generated, types of litter materials used, methods of wastes collection, predisposal wastes treatment, wastes utilization and possible effects of the wastes on the environment. Additional information was collected through personal communication and focused group discussions during the field trips while administering the questionnaires. Points of information gathering were commercial poultry and livestock farms, homesteads, dip tanks and feedlots. The data were analysed using percentages and frequencies, and the results presented in tables. Major solid wastes generated were from animal dung, poultry droppings and litters. Saw dust was the most popularly used litter material by about 38.7% of the large scale establishments while crushed corn cob was the least used by about 5.3%. Urine and spent water from washing in milking parlours and dip tanks constituted the liquid wastes. Waste collection was by manual scrapping with spades, sweeping and floor washing using water hoses, and use of mechanical scrappers. Manual scrapping was the most predominant method for solid wastes collection. It was used by about 60% and 95.8% of the large scale establishments and homesteads respectively. Mechanical scraping was mainly used in the large scale establishments. Solid wastes were either collected and taken directly to the field for application or temporarily stored in compost pits and refuse dumps to undergo further decomposition. Only 33.3% of the homesteads had temporary dump sites. In most homesteads, kraal manure is removed during land preparation which eliminates the need for storage. About 33.3% of the large scale establishments had dump sites, 17.4% had compost pits while 16% had a combination of dumpsites and compost pits. Liquid wastes were disposed off on strip fields or adjacent streams. About 75.0% of the homesteads and 33.3% of the large scale establishments conveyed their wastes using wheel barrows while 4.2% and 26.7% respectively made use of a combination of wheel barrows and tractor trailers. All the homesteads and about 72.0% of the large scale establishments used solid wastes as fertilizers on their own farms. Liquid effluent was used for irrigation by about 5.3% of the large scale establishments. The ministry of agriculture and cooperatives is emphasizing the use of livestock wastes in fish farming while the biogas plants which were established to utilize some of the wastes have been abandoned. Respondents admitted awareness of the dangers inherent in poor livestock and poultry wastes management but only a few admitted that their management techniques constituted any hazards to the environment. Solid wastes as presently generated, collected and utilized constitute no environmental threat but the liquid discharged to streams and wet cattle that wade through streams immediately after dipping are considered potential sources of pollution. Wastes are a potential source of biogas which is being effectively utilized in many countries. The abandoned biogas pilot schemes should be reactivated. Water quality assessment should be carried out on streams to which wastes are discharged and appropriate steps taken to prevent pollution. Oxidation ponds should be constructed near dip tanks and milking parlours. More extension work is required to educate the rural populace on the use of livestock wastes for fish farming. 1 results 1

- Imported Used Electronics (IUEs) are officially conceived in research oriented policy as potential and actual toxic “solid waste”, yet Nigeria remains a high consumer demand economy for them. IUEs include electronic monitors, digital devices, docking stations, cell phones, hand-held diagnostics, screening tools, television sets among others. Nigerian economy has evolved a socially constructed merchandise structure, which sustains IUEs trade. Literature, however limits IUEs discourses to pure-scientific framing of toxicology and dump in the Third World countries. This study, therefore, examined the subjective meanings that sustain the demand and merchandise of IUEs against official prohibition. Social action theory guided the study. The research design was exploratory. The qualitative research method was used. Data were generated from both primary and secondary sources. The research area was Lagos, and data were collected from Ikeja Computer Village, Westminster Used Electronics Market, Alaba International Market, Apapa Customs Office (ACO) and National Environmental Standards and Regulatory Enforcement Agency (NESREA). Participants were selected through purposive and snow-balling techniques. Non-participant observation for 15 months, In-depth Interviews (IDIs) were held with 22 IUE consumers and 22 market-actors. A total of 15 Key Informant Interviews (KIIs) were held with ACO officers (three), Association Heads of the three markets (eight) and veteran market actors (four). Six FGDs were conducted with IUEs consumers and market-actors, while five case studies were carried out on large scale consumers and market actors with at least 10 years working experience in IUEs merchandizing. Secondary data were sourced from NESREA and Basel Convention Coordinating Centre for Training and Technology Transfer for African Region, Ibadan. Data obtained were content analyzed. Demand for IUEs was hinged on peculiar social relations of consumption and merchandising which rationalized and constructed IUEs as desirable and affordable modern material objects. This relations involved processes of upgrading “solid waste” into tradable commodities infused with deluxe values and potentialities for leveling class. Artful transactions involved offer of disused electronics to market-actors in exchange for upgraded IUEs at a little token. A structure of interdependent actors sustained the IUEs merchandise. It included official gatekeepers such as Customs and NESREA, whose variable roles sustained entry of solid wastes into the market as IUEs; and administrators, merchants and interlinks-security who provided administrative, economic and coercive functions respectively. Furthermore, resuscitators upgrade otherwise wastes into merchandisable goods. Scavengers-collectors extract the irredeemable from merchants, to scrap-collectors who trade them to bulk-scrap-buyers. Bulk-buyers in turn, trade the scraps to domestic iron-smelting companies and/or illegally export them. In essence, IUEs remained tradable even in their end-of-life stages. Thus, local meanings of utility of IUEs and of employment potentialities were constructed against official policy perception of them as solid waste. Through a structured system of market interactions, actor-merchants contrived utility for Imported Used Electronics in the process of merchandise and consumption. Government should therefore accommodate local realities in order to proffer inclusive and robust IUEs policy. 1 results 1

- Over the years, the increase in numbers of prison inmates and the detrimental effect of incarceration on the families and society at large have raised severe attention and concern. Studies have documented the effects of incarceration and some psychological factors of prison inmates but there is a dearth of research on quality of life among spouses of prison inmates. This study, therefore, investigated perceived social support and financial well-being as predictors of quality of life among prison inmate spouses in Ogun State. Descriptive cross- sectional survey research design was adopted, utilizing a purposive sampling technique to select the participants across correctional centres in Ogun State. A total of 281 spouses of prison inmates with mean age of 41.6yrs and SD (11.2) participated in the study. Self report questionnaires measuring quality of life (.69), perceived social support scale (76) and financial wellbeing scale (.77) were used for data collection. Three hypotheses were tested using appropriate statistics. Findings revealed a significant relationship between perceived social support and quality of life (r = .22; p<.01) and between financial wellbeing and quality of life (r = .54; p<.01). Also, financial well-being and perceived social support jointly contributed 5% variance in quality of life (R = .23; R2 = .05; F (2, 279) = 4.66; P<.05); further analysis revealed that financial well-being (β = .23; t= 3.53; p<05) and perceived social support (β = .19; t= 2.76; p<.05) independently predicted quality of life. It was concluded that perceived social support and financial well-being were significant correlates of quality of life. Based on these findings, it was recommended that, relations and friends should provide adequate psychosocial and financial supports for spouses of prison inmates to preserve and strengthen positive family connections, promote the quality of life and ensure a healthy society 1 results 1

- Soil erosion risk assessment and landuse planning strategics have become increasingly more data-intensive, sophisticated and highly complex involving myriads of quantitative and qualitative techniques. One of the methods that can help in synchronizing all these diverse data sets within a decision making framework is the analytical hierarchical process (AHP) developed by Satty. AHP provides a better technique for the comparison of factors based on decision matrices. It also provides structured methods for the incorporation of experts’ opinions in the ranking of factors. This study examines the use of the AHP in modelling soil erosion risk using Universal Soil Loss Equation (USLE). Rainfall data, landuse/landcover, digital elevation data, soil erosivity index, supporting practices and expert opinions were integrated using AHP to identify areas with varying degrees of erosion risk potential. A pairwise comparison of the four factors identified by experts and supported by the USLE model was performed by means of Saaty's square it is a reciprocal matrix with unit rank whose eigenvector solution gives the priority or the relative importance, or dominance, of the elements on a ratio scale. The inputs to the matrix were derived from field survey and expert opinions on the relative dominance of the elements within each pair by using a nine-point scale. The approach retains the quantitative conceptual elements of the USLE methodology while allowing for a qualitative assessment and ranking of pertinent factors of soil erosion at micro level. The study shows that hilly areas with high rainfall particularly in the urban areas have the highest erosion risk potential while the natural forest areas have the least. It therefore shows the utility of AHP in coupling existing models with expert opinions as well as some subjective indicators in decision making. The method was capable of ranking ecosystems in terms of environmental conditions and suggesting cumulative impacts across a large region. 1 results 1

- The aim of this study is to identify the place of women in the use of information in large scale agricultural development process in Ijaye community of Akinvele Local Government Aiea of Oy o State. This is with a view to providing valuable data for government. NGOs and other Policy making bodies, to guide in developing the agricultural development programmes. Two hundred and forty copies of a questionnaire were administered Ip respondents, which include women farmers and extension workers. Also, data wet e collected through the focus group discussion oral interview and existing comparative literature. It was revealed that only a very small percentage of women farmer were involved in fairly large-scale agriculture.' Factors responsible for this include non-allocation of land to women, lack of relevant information on agriculture and lack of funds. Nevertheless, the very few that were engaged in fanning utilize the information at their disposal maximally. 1 results 1
- The capture and storage of carbon dioxide (CCS) produced during the combustion of fossil fuels now offers one option for attaining large scale reductions in the emissions of greenhouse gases and thus, promote a clean environment. It is now becoming clear that CCS technologies could promote the use or consumption of fossil fuels than otherwise previously thought. This paper presents an overview of the techniques involved in the capture and sequestration of carbondioxide(CO). The opportunities and the challenges of the application of CCS in Nigeria are considered. It is concluded that the development of gas utilization schemes and power plants makes it imperative for Nigeria togive attention to CCS technologies. 1 results 1
- The study sought to determine the sources and types of information used by agricultural engineers in Nigeria and the extent to which the information usuage of agric enginneers determines their productivity level. The study made use of 261 agricultural engineers who were selected by stratified random sampling techniques according to their different places of work. Data was collected through the use of questionnaire tagged Information Utilization Scale (IUS). The data was analyzed using percentages and simple correlation statistics. The results shows that a large percentage of the respondents utilize agricultural engineering textbooks and manuals (67.8%), journal publications (66.7%), and conference/workshop papers (66.7%) to great extent. However, the result established that 67% of the respondents do not use information about laws and states, adminstrative rules and executive order. Moreover, the result shows that on the average the repondents altogether produced one published research paper, two conference paper, one extensive pamphlet, two research designs, one prototype and two- fabricated equipment per year. 1 results 1
