Pregnancy Outcomes Among The Ibani Of Rivers State, Nigeria: Findings From Case-Studies

The prevalence of high maternal and infant morbidity/mortality among the Ibani of Rivers State, Nigeria, is linked to socio-cultural factors that influence perceptions, attitudes and practices of the people with regard to pregnancy. This study investigates the factors affecting pregnancy outcomes among the Ibani by examining 19 cases identified through Exit-interviews (EIs). Findings indicate that pregnancy outcomes depend on the interaction of complex variables such as male role, socioeconomic status of women, child spacing, access and use of maternal health facilities, among others. The results show that there are 4 principal types of pregnancy outcomes among the Ibani, which include: Type-1 representing maternal and infant survival; Type-2 which is synonymous with maternal survival but infant mortality; Type-3 or spontaneous abortion; and Type-4 which represents maternal mortality but infant survival. The findings suggest that multiple social, cultural and ideological factors condition behaviours among the Ibani and that pregnancy outcomes are only comprehensively understood in the context they occur

Sustainability-Oriented Practices of Eco-Innovation, Eco-Commitment and Organizational Performance of A Developing Economy

This study presents an empirical investigation of Sustainability oriented practices of Eco-innovation, Eco-commitment and organizational performance of a developing economy. This study was also motivated by the need to solve the environmental problems caused by the activities of profit driven entrepreneurs in developing economy as well as exploring the benefits to organizations. The study was guided by three key objectives, from which appropriate research question and hypotheses were formulated. The specific objectives of this study were (1) to ascertain the extent to which eco-commitment practice affect the selected manufacturing firms employee job satisfaction. (2) To establish the degree to which eco-innovation affect market share of selected manufacturing firms in a developing economy. This study adopted the survey design. Simple random sampling technique was used in selecting the 10 manufacturing firms in Nigeria. A sample size of 543 respondents was determined from the population of 5705 drawn from management, middle and lower cadre of the selected manufacturing firms using Cochran (1977) statistical formula. A stratified sampling technique was also used to determine the proportional allocation of questionnaire to management cadre, middle cadre and lower cadre. Designed questionnaire and personal interview were used for primary data collection. The questionnaire was structured on 5-point Likert scale. The validity of the instrument was ascertained using content validity. The instrument was checked for Reliability using test re-test method through Cronbach alpha with a value of 0.90, which shows consistency in the items of survey. Data were analyzed and the hypotheses were tested using linear regression analysis. Probability level of significance was given at 5%. Data were presented using simple percentage. Findings revealed that Eco-commitment practice had a significant and positive effect on employee job satisfaction (r=.514aF=88.065T=9.384p-.000). Eco-innovation had a positive effect on the market share of selected manufacturing firms in a developing economy. In conclusion, the implementation of green business practices, principles and processes will lead to very positive outcome that will be visibly manifested in the organization and the environment

Effects of spent engine oil contamination on soybean (Glycine max L. Merril) in an Ultisol

An experiment was conducted in the University of Nigeria Nsukka Teaching and Research Farm to determine the effect of spent auto-engine oil on soil and soybean in a Randomized Complete Block Design. Treatments were four levels (0, 1, 2 and 3 %) of spent auto-engine oil (SPO). Top soil samples were collected at 0, 12, 24 and 36 months and analyzed. Results indicated that infiltration rates in plots under 3 % SPO was reduced from 1.40 cm h-1 in control plots to the lowest value of 0.07 cm h-1 compared to 0.27 cm h-1 in 1 % treatment in the first 12 months. Plots contaminated with 3 % SPO gave the lowest Ks values of 6.29, 7.68 and 9.43 cm h-1 in the 12th, 24th and 36th months respectively. Data on plant samples showed that 2 % and 3 % SPO contaminations reduced soybean germination from 99 % (control) to 86 and 68 % respectively in the first cropping season whereas 1 % SPO was observed to significantly increase leaf area, dry matter content and grain yield from control values of 52.6 cm2, 3.01 t ha-1 and 0.72 t ha-1 to 54.5 cm2, 4.20 t ha-1 and 0.97 t ha-1 respectively.Keywords: Contamination, soybean, soil physical properties, spent engine oil, Ultiso

Effect of Vitamin C Supplementation on platelet aggregation and serum electrolytes levels in streptozotocin-induced diabetes mellitus in rats

Diabetes mellitus (DM) is a disease condition characterised by hyperglycemia; free radical and abnormal haematological indices. Vitamin C can reduce free radical generation and ameliorate adverse conditions of diabetes mellitus. The aim of the present study is to investigate the effect of vitamin C on platelet aggregation and electrolyte levels in Type 1 DM. Male Wistar rats were divided into four groups namely control, DM, DM +Vitamin C and Vitamin C groups. Rats were made diabetic with a single dose of streptozotocin (65 mg/kg) intraperitoneally. Vitamin C was administered orally to diabetic and normal rats at 200 mg/kg body weight for 28 days. Blood samples were analyzed for hematological parameters, platelet aggregation, and serum electrolyte levels. Blood glucose in DM+ Vitamin C group (9.9 ± 1.8 mmol/L) was significantly reduced (p<0.01) compared to DM group (32.2 ± 2.1 mmol/L) and significantly higher (p<0.05) than control (4.4 ± 0.8 mmol/L). Haemoglobin (Hb) concentration in DM group (12 ± 0.1 g/dL) was significantly reduced (p<0.01) when compared with control groups (14 ± 0.24 g/dL) and significantly increased (p<0.05) in the DM+vitamin C group (13.5 ± 0.5 g/dL) compared with the diabetic group. The mean corpuscular volume values in DM (68.66 ± 0.5 fL) and DM+vitamin C groups (68.11 ± 0.4 fL) were significantly higher (p<0.01) than the control (59.49 ± 0.5fL). Platelet count in DM group (523 ± 8.5 x109/L) was significantly raised (p<0.01) when compared to control (356 ± 6.2 x109/L) and significantly reduced (p<0.01) in DM+ vitamin C-treated group (385 ± 7.8 x109/L) compared with DM group. Platelet aggregation and serum sodium/potassium ratios was significantly reduced (p<0.01) in DM+vitamin C compared with DM group. These results suggest that oral vitamin C administration increases haemoglobin, reduced plasma glucose level, platelet count, serum sodium/potassium ion ratio and inhibits platelet aggregation in streptozotocin-induced DM in rats.Keywords: Diabetes mellitus, electrolytes, Haematological parameters, Platelet aggregation, Red cell indices, Vitamin

Implementation of Family Life and HIV/AIDS Education in Nigerian Schools: A Qualitative Study on Scope, Delivery and Challenges

This study utilized data from Focus Group Discussions and In-depth Interviews among secondary school students and teachers to examine the scope, delivery and challenges of FLHE implementation within states and across geopolitical zones in Nigeria. Structural Functionalism, Rational Choice and Differential Association theories were adopted as theoretical framework. Results show that several patterns in classroom teaching of FLHE are identifiable across the country. The study found that FLHE is taught at the Junior Secondary and Senior Secondary levels with variations among States on the beginning levels. The main mode of FLHE delivery is classroom instruction; other modes include assembly talk and sensitization by organizations. Despite paucity of Information, Education and Communication materials and inadequate personnel requirement, different stakeholders noted that FLHE has been beneficial to students. Therefore, effective implementation of FLHE will go a long way to ensuring that young people in Nigeria are equipped with necessary information to enable them exhibit the right attitude and behaviour towards sexuality issues. Keywords: FLHE implementation, reproductive health, young people, youth corpers, sexual attitude.RésuméCette étude a utilisé des données provenant des groupes de discussion à cible et des entrevues en profondeur entre élèves et enseignants des écoles secondaires afin d'examiner la portée, l’actualisation et la mise en oeuvre de défis de la VFES au sein des Etats et entre les zones géopolitiques au Nigeria. Le fonctionnalisme structural, le choix rationnel et les théories l’association différentielle ont été adoptés comme cadre théorique. Les résultats montrent que plusieurs tendances dans l'enseignement en classe de la VFES sont identifiables à travers le pays. L'étude a révélé que la VFES est enseigné dans les deux cycles de l’école avec des variations entre les États à l’égard du niveau de commencement. Le principal mode de la réalisation de la VFES est l'enseignement en classe; d'autres modes comprennent des discours pendant la réunion matinale et la sensibilisation par les organisations. Malgré la rareté de l'information, l’éducation et les matériels de communication et les besoins insuffisants en personnel, les différents intervenants ont noté que la VFES a été bénéfique pour les élèves. Par conséquent, la mise en oeuvre effective de la VFES aidera beaucoup à assurer que les jeunes gens au Nigeria sont équipées d’informations nécessaires pour leur permettre de démontrer une bonne attitude et un bon comportement à l'égard des questions de sexualité. Mots-clés: la mise en oeuvre FLHE, santé de la reproduction, les jeunes, jeunesse, attitude sexuell

Uncertain pasts and risk-sensitive futures in sub-Saharan urban transformation

This chapter explores the status and the scope for transition of risk- sensitive and transformative urban development in diverse cities of sub-Saharan Africa. Sub-Saharan Africa is important because of its large proportions of urban populations with high vulnerability and growing exposure to risks. High rates of urban growth pose increasing risks as we go into the future, yet there is also opportunity to reduce risk through integrating risk management into development. However, this opportunity space is often constrained by limited capacities to plan and manage the rapid urbanisation process, particularly in informal settlements. Limited capacities to prevent processes of risk accumulation pose threats to poverty reduction and sustainable development. In this context, there is an increasingly urgent need for squarely recognising and addressing the underlying vulnerabilities of urban populations and their root causes. Transitioning towards such sustainable urban pathways will require the strengthening of capacities and accountability of city authorities and broader governance systems, both formal and informal

Prediction Models for Water Erosion Risk Management: A Review

In order to estimate the potential soil erosion hazard of an area, erosion prediction models are needed. Various models have been used by researchers, which ranges from mathematical and conceptual simple approaches to complex models that try to include the complexities of the real world. Six (6) models are reviewed in relation to their suitability for use. The KINEROS, CORINE and EUROSEM were best suited for water erosion risk prediction in cultivated soils. On the other hand, the KINEROS, PESERA, CORINE and EUROSEM were found to be applicable in all sectors (Agronomy, water resources management and road construction) highlighted. The GLASOD had the least applicability with respect to this study.Keywords: Water Erosion, sediment transport models, Model structure and suitability for us

Towards risk-sensitive and transformative urban development in sub Saharan Africa

Risk-sensitive urban development is required to reduce accumulated risk and to better consider risk when planning new developments. To deliver a sustainable city for all requires a more frank and comprehensive focus on procedure: On who makes decisions, under which frameworks, based upon what kind of data or knowledge, and with what degree and direction of accountability? Acting on these procedural questions is the promise of transformative urban development. This paper explores the status of risk sensitive and transformative urban development and the scope for transition towards these components of sustainability in urban sub-Saharan Africa through the lens of diverse city cases: Karonga (Malawi), Ibadan (Nigeria), Niamey (Niger) and Nairobi (Kenya). The paper draws from a 3-year research and capacity building programme called Urban Africa: Risk Knowledge that aims to address gaps in data, understandings and capacity to break cycles of risk accumulation. A common analytical framework is presented to help identify blockages and opportunities for transition towards a risk-sensitive and transformative urban development. This framework is then illustrated through each city in turn and a concluding discussion reflects on city observations to draw out recommendations for city level and wider action and research partnerships

Appraisal of Heavy Metal Contents in Commercial Inorganic Fertilizers Blended and Marketed in Nigeria

Abstract Human food chain toxicity has been shown to be influenced by application of inorganic fertilizers. Three samples of commercial inorganic fertilizers marketed in Nigeria were analysed for their heavy metal contents. The fertilizer samples used were N 15 P 15 K 15 (CF1), N 20 P 10 K 10 (CF2) and N 27 P 13 K 13 (CF3). Molybdenum (Mo) levels were the highest and Vanadium (V), Arsenic (As), Mercury (Hg) and Silver (Ag) were not detected by our analytical method. The concentrations of Mo in the CF1 (2, 570.0 mg/kg), CF2 (2,3000.0 mg/kg) and CF3 (1,340.0 mg/kg), were above the maximum acceptable concentration (20mg/kg) while CF1 (0.129 mg/ha/yr) and CF2 (0.115 mg/ha/yr) were above the maximum annual metal addition to soil (0.079 mg/ha/yr), as established by Canadian standard for fertilizers. Only CF1 (5.805 kg/ha) was above long-term cumulative assessment of metal addition to soil (3.57 kg/ha). Other heavy metals detected were Magnesium(Mg), Iron(Fe), Nickel(Ni), Zinc(Zn), Cadmium(Cd), Manganese(Mn), Cupper(Cu), Cobalt(Co), Lead(Pb), Chromium(Cr) and Boron(B). Cd and Pb mean concentrations of the fertilizer samples examined ranged from 2.84 to 11.32 mg/kg and 7.43 to 9.02 mg/kg respectively. Cd followed significantly (p<0.05) with phosphate percentage by weight of the inorganic fertilizers. Though the concentrations of these non-nutrient/toxic metals were below the recommended levels, it is important to encourage manufacturers to indicate their concentrations on the fertilizer labels in view of their health implications

AIDS knowledge and attitudes in a Turkish population: an epidemiological study

BACKGROUND: The aim of this study was to investigate and present some pertinent comments concerning Acquired Immunodeficiency Syndrome (AIDS) knowledge, attitudes and misconceptions among the general population in a city of west Turkey. This study was deemed important and relevant due to the increasing importance of AIDS in Turkey and the other countries. METHODS: Using a multistage area sampling method, a random sample of individuals aged 11–83 years, living in 65 different quarters in the city of Eskisehir, Turkey during September, October and November 2004 were interviewed. RESULTS: In all, 1048 respondents completed the survey. In most items, respondents displayed a fairly good to excellent degree of knowledge about HIV/AIDS. Individuals with higher degrees of education indicated more correct responses in all items relating to knowledge of HIV/AIDS. In general, the respondents' attitudes towards AIDS and people with AIDS were found to be tolerant and positive, with one answer choice showing that the majority of the respondents agreed with the statement that those with HIV/AIDS must be supported, treated and helped (90.7%). Moreover, the proportions of the respondents' misconceptions were found to be significantly low for all the items. However, nearly one fourth of the respondents agreed with the misconceptions 'AIDS is a punishment by God' and 'One is not infected with HIV/AIDS if engaged in sport and well nourished'. CONCLUSION: In general HIV/AIDS related knowledge was high and people showed positive attitudes. However, people continue to hold misconceptions about AIDS and these need to be addressed by health education programs targeting those at higher risk
