These findings are part of a larger study on the experiences of nurses and midwives providing postpartum care in rural areas of Kenya. Besides being the main healthcare providers in rural areas, nurses in low resource countries have limited access to continuous professional development. <strong><em>Research design</em>:</strong> This is a qualitative research guided by critical theory and Foucault’s concepts of power and knowledge. Focused ethnography provided the framework of data collection and analysis. 23 in-depth interviews were contacted, and thematic analysis was used for data analysis. Reflexive memos kept throughout the research process helped to ensure the trustworthiness of data. <strong><em>Findings</em>:</strong> This paper will focus on the theme of continuing professional development (CPD) as a resource for a healthy work environment. While the knowledge of the nurses and midwives allowed them to provide care to the mothers and their infants adequately, personal and structural barriers prevented them from participating in continuing professional development. <strong><em>Discussion and Conclusion</em>:</strong> A well-prepared nursing and midwifery workforce could have the capacity to transform the health outcomes of their clients through the application of evidence-based practices. Therefore, courses that are context-appropriate and meet the needs of different learners should be available to support the nurses’ and midwives’ professional growth.

Little is known about how CPD participants put the experience and the new knowledge into practice and whether it has impact on patient care outcomes. The primary objective of this study was to evaluate the effectiveness of CPD of Midwives on Essential Maternal and Newborn care skills on maternal and neonatal mortality in Embu County, Kenya. The study was an interventional non-randomized pretest post test study design of midwives from the participants of the 2010 ministry of health training on essential maternal and newborn care skills. Sixty (60) midwives working in maternity unit of Embu level five hospitals were targeted. The study was carried out in two phases. Phase one involved environmental scanning of the factors that support good performance in the workplace using a questionnaire. Phase two involved evaluation of the impact by testing a hypotheses using data collected by use of questionnaires, evaluation checklist and chart audit. Data were analyzed using qualitative content analysis and presented using percentages and frequency tables. Chi-square test and correlation analysis were used to show the association between variables, which are midwives essential maternal and newborn care skills and maternal and neonatal mortality. A chi-square χ<sup>2</sup> = 14.143, df = 9 and a coefficient = 0.357. This coefficient is less than p-value at Alpha 0.05 and therefore is not significant, proving that the essential maternal and neonatal care skills do not contribute to reduction in mortalities as such two variables are almost independent of each other, whether one exists does not necessitate the existence of another nor does it reduce maternal and neonatal mortalities in Kenya.展开更多

It is however effective when the training targets the appropriate needs of the target beneficiaries. This study was therefore aimed at identifying priority training needs of Primary Care Level health professionals in rural Western Uganda. <strong>Methods:</strong> This was a descriptive cross-sectional survey among 35 rural community health facilities represented by their managers in rural Western Uganda. Participants were invited to Mbarara University of Science and Technology and responded to a self-administered questionnaire and also participated in qualitative group discussions guided by Facilitators from the Community Based Education and Research Services unit within the Community Health Department of Mbarara University of Science and Technology. Priority health training needs were determined based on the computed weighted scores. <strong>Results:</strong> The majority of managers of rural primary care level health facilities were medical officers by the level of training (51.43%) and male by gender (68.57%). Priority health training needs identified were child health and maternal health with total weighted scores of 12.0 and 10.9 respectively. Qualitatively, emerging themes included;leadership and management, and supervisory roles during student field attachments.<strong> Conclusion:</strong> Priority health training needs at rural Primary Care level health facilities were child health, maternal health, leadership and management, and supervisory skills. There is dire need to train rural primary care level, health professionals. In-service training based on identified needs should be offered by MUST in partnership with regional stakeholders. This is likely to enhance the quality of services provided by rural primary care level health facilities.展开更多

Methods: An online questionnaire, which explored the motivation and preferences of the pharmacists to lifelong learning, was sent to all members of the Royal Dutch Pharmaceutical Society (4321) in the Netherlands. The data were analysed using a non-hierarchical clustering technique. Key findings: Two clusters of pharmacists were discovered. Cluster A pharmacists (n = 474) were more motivated by credit points (63.5% vs. 47.2%), personal interest (84.1% vs. 56.3%), updating knowledge (73.8% vs. 56.8%) and topicality of CE courses (47.7% vs. 26.1%). Cluster B pharmacists (n = 199) were predominantly motivated by the aspect "duty as a care-giver" (97.0% vs. 0 % in cluster A). Pharmacists who belonged to cluster A tended to be women (60.5%), often worked part-time (29.3%) and mostly preferred lectures (71.1%). Cluster B pharmacists consisted of statistically significantly more male pharmacists (52.8%, p = 0.001), worked more full time (77.4%, p = 0.009) and mostly preferred blended learning (62.3%, p = 0.047). Conclusions: These results suggest the use of different education formats for different kinds of pharmacists to participate in CE activities.展开更多

Many continuous professional development (CPD) activities have been conducted (e.g., national teaching contest) to improve CE teachers' teaching effectiveness, an essential component of teacher learning. However, it has remained unknown concerning how teacher learning takes place in these well-intended CPD activities, and what mediating factors play an important role in teacher learning. To address this gap, this case study reports on a CE teacher's (]anna, pseudonym) experience in preparing for and participating in an English teaching contest. Drawing upon multiple sets of data such as teacher reflective journals, interviews, observations of group discussions, and video-recorded teaching demonstration and lesson plan presentation, the findings reveal that teacher learning takes place at a superficial level through legitimate peripheral participation, yet at a deeper level through identity crisis. Vulnerable teacher learning is also identified in the CPD activity, with differentiated learning possibilities created by the tensions between resources and power relations within the community and the teacher's conceptions of teaching and learning. The study concludes with implications for research of teacher learning and practice for teacher professional development.展开更多

However, their coupled effects on rhizospheric microbial communities under a continuous vegetable cropping system have not been adequately addressed. The objective of the present study was to assess the effects on soil microbial community and yields of waxy maize(Zea mays L.) intercropped with or without residue retention in a continuous broccoli(Brassica oleracea L.) cropping system, i.e., relay intercropping of broccoli and waxy maize(B/M-B), relay intercropping of broccoli and waxy maize with residue retention(B/MR-B), and broccoli monoculture(B-B). The biomass yields of spring and autumn vegetables in B/MR-B were 16.3%–32.5% and 30.1%–46.1% higher than those of B-B,respectively. Autumn vegetable economic yields of B/MR-B were 28.2%–40.3% higher than B-B. The average well color development followed the order: B/MR-B &gt; B/M-B &gt; B-B. The Shannon index, Simpson index, and Mc Intosh index were higher in B/MR-B than under monoculture. A principal component analysis showed that microbial communities of B/MR-B soils differed from those of B/M-B and B-B soils. Carbon(C) sources utilized by the rhizosphere microorganisms were mainly carbohydrates, carboxylic acids, amino acids, and polymers; however, the C sources for the soil microbial community differed between intercropping and monoculture. The communities from B/MR-B preferred amino acids and polymers. Available nitrogen(N), potassium(K), and phosphorus(P) had an obvious impact on soil microbial community. Additionally, the C source utilization by microorganisms was significantly affected by p H and available K and P. Cropping system diversification through relay intercropping and residue retention effectively improved the functional diversity of the soil microbial communities and increased the yields of vegetables.展开更多

However, their coupled effects on rhizospheric microbial communities under a continuous vegetable cropping system have not been adequately addressed. The objective of the present study was to assess the effects on soil microbial community and yields of waxy maize(Zea mays L.) intercropped with or without residue retention in a continuous broccoli(Brassica oleracea L.) cropping system, i.e., relay intercropping of broccoli and waxy maize(B/M-B), relay intercropping of broccoli and waxy maize with residue retention(B/MR-B), and broccoli monoculture(B-B).
