Distribution of fur seals Arctocephalus australis has been studied in October 2007 on the western, southern and eastern Falkland shelves during the survey of spawning grounds of the red cod, Salilota australis. Fur seals presence/absence, numbers and sex were recorded at every oceanographic station. Animals were found foraging on the shelf edge south-west of the islands, in a productive zone with quasi-stationary eddies at a periphery of upwelling. It was also the zone of maximum abundance of lobster-krill, Munida spp.—an important food source of fur seals and aggregations of both red cod and blue whiting, Micromesistius australis. No fur seals were found in waters of the relative cold and saline Falkland Current as well as in the relatively warm, fresh and oxygen-rich waters of Argentine Drift. It allows supposing that position and extension of the foraging grounds are caused by oceanographic features determining distribution of prey species.

Mobile Money is an innovation that has transformed e-business in the Cameroonian context. This study examines the factors that enhance the adoption and use of mobile money in Buea, capital of the South West Region of Cameroon. The theoretical framework used is the diffusion of innovation. The qualitative approach is adopted, with 10 mobile money operators and 10 mobile money users interviewed using a structured interview protocol. Results show that participants prefer adopting and using mobile services because they are easy to use, convenient, readily accessible, and have less charges compared to the traditional banking system. Telecommunications companies should therefore, continue to consider less charges and bonuses as a strategy to increase penetration and adoption of mobile money services. Likewise, the instructions and language essential to effect Mobile Money operations like internet and airtime purchase should remain simple.

Background: Nursing is a profession that is concern with ensuring high quality of patient care. To providing quality care, participation in research and research utilization is very necessary. Objective: This study was designed to study factors influencing nurses’ involvement in research and utilization of research findings among nurses of a Teaching Hospital, South west, Nigeria. Method: A descriptive design was used. Convenient sample technique was used to select 198 Nurses and Self-developed questionnaire with reliability index of 0.875 was used for data collection. Data collected were analyzed using SPSS package. Descriptive and inferential statistics were used to test the hypotheses and results were presented in tables. Result: The outcome of the study showed that 153(77.3) have never carried out any research while70 (35.4%) have never make use of research findings. Factors such as time, organizational policy, mentorship, funds and knowledge of research are some of the major factors influencing the involvement of nurses in research while awareness of research findings, time to read research findings, support from colleague, unpublished research influenced utilization of research findings. There was a significant relationship between: support from colleagues and nurses’ utilization of research findings (p=0.001); between unpublished research and nurses’ utilization of research findings( p-value= 0.000); between time to implement new ideas and the utilization of research findings by nurses (p=0.005); between organizational support and nurses’ utilization of research findings (p= 0.001); between the presence of research committee and nurses’ utilization of research findings (p= 0.000). Conclusion; numerous factors highlighted above are noted to influence nurse’s participation and utilization of research findings; hence, a multidimensional approach should be applied in solving the problem.

Introduction: Vaccine preventable disease remained issue of major concern to the global health system. Low coverage of immunization necessitated the need to explore the determinants of immunization uptake. Factors influencing immunization coverage in South-West Nigeria were investigated in this study. Methods: Data from the Nigeria demographic and health survey (NDHS) was used for this study. Our focus was on children between 12 to 23 months whose parents were residents of South-West Nigeria. A total of 655 records were used for the analysis of this study. The outcome variable (child’s immunization status) was categorized as “non-or- under immunized and fully immunized”. Considered explanatory variables were children and parents’ characteristics. Data were analyzed using Statistical package for social sciences (SPSS) version 25. Descriptive statistics were presented and generalized linear model was used to explore the determinants of immunization completeness. Results: Of the 665 children whose mean age was 16.7 ± 3.4 SD months, 62.3% were non-or-under immunized, while only 79.8% were birthed in the health facility. Majority of them (65.1%) were not presented for postnatal check within two months of birth while 51% do not have health card. About 79% of the mothers said distance to the health facility was not a problem. In this study, postnatal check within 2 months of birth, type of residence and ownership of health card were identified factors influencing the uptake of immunization. For instance, Those who said distance is a problem were 3 times less likely to fully immunize their children (AOR=0.28, p=0.000, 95% CI: 0.16-0.47). Obviously, ownership of health card (AOR=15.34, p=0.000, 95% CI: 9.86-23.88) and postnatal check within 2 months of birth (AOR=1.78, 95% CI: 0.37-0.86) were associated with the likelihood of complete immunization. Conclusion: Immunization uptake was very low in South-West Nigeria. Factors that were positively associated with completeness of immunization include observance of postnatal check and ownership of healthcare card while problem of distance to health facility was negatively associated. Increasing vaccination coverage/ completeness would ameliorate, if policy geared towards the improvement of postnatal check-ups, distribution of healthcare facilities within residential areas and strict adherence to the use of health care are considered in the South-West Nigeria.
