Ryzyko geopolityczne, globalizacja i degradacja środowiska w Afryce Południowej: dowody z zaawansowanego podejścia kwantylowego

Sustainable development involves the incorporation of socio-economic concerns and environmental protection into the economic decision-making process, in such a way that, any developmental effort would eventually be favorable to immediate and future generations. It is against this backdrop this study investigates the effects of geopolitical risk and globalization on environmental degradation in South Africa over the period 1985Q1-2018Q4. This study improves on existing studies and raises concerns on the potential twin-effect of geopolitical risk and globalization on the environment. We deviate from the existing studies that make use of the mean causality approaches that do not consider possible dependence in the conditional tail of the series distribution. To examine whether the causality exists among the series, we make use of the novel Troster (2018) Granger non-causality in condition quantiles, which captures the pattern of causality in various quantiles. Empirical results show that there is feedback causality nexus between geopolitical risk and CO2 emissions. In majority of the quantiles, feedback causality is also observed between globalization and CO2 emissions. We find a bidirectional Granger causality nexus between geopolitical risk and environmental degradation, and between globalization and environmental degradation. Globalization and geopolitical risk negatively influence environmental degradation. We conclude that environmental degradation is not driven by globalization and geopolitical risk in South Africa, among other policy suggestions.Zrównoważony rozwój polega na włączeniu kwestii społeczno-ekonomicznych i ochrony środowiska do procesu podejmowania decyzji gospodarczych w taki sposób, aby wszelkie działania rozwojowe były ostatecznie korzystne dla najbliższych i przyszłych pokoleń. Na tym tle niniejsze badanie analizuje wpływ ryzyka geopolitycznego i globalizacji na degradację środowiska w Afryce Południowej w okresie 1985Q1-2018Q4. Badanie to budzi obawy dotyczące potencjalnego podwójnego wpływu ryzyka geopolitycznego i globalizacji na środowisko. Odchodzimy od istniejących badań, które wykorzystują podejście do średniej przyczynowości, które nie uwzględnia możliwej zależności w warunkowym ogonie rozkładu serii. Aby zbadać, czy istnieje związek przyczynowy między szeregami, korzystamy z Trostera (2018) Grangera bezprzyczynowości w kwantylach warunkowych, która oddaje wzorzec przyczynowości w różnych kwantylach. Wyniki empiryczne pokazują, że istnieje związek przyczynowo-skutkowy sprzężenia zwrotnego między ryzykiem geopolitycznym a emisjami CO2 . W większości kwantyli obserwuje się również przyczynowość sprzężenia zwrotnego między globalizacją a emisjami CO2 . Znajdujemy dwukierunkowy związek przyczynowy Grangera między ryzykiem geopolitycznym a degradacją środowiska oraz między globalizacją a degradacją środowiska. Globalizacja i ryzyko geopolityczne negatywnie wpływają na degradację środowiska. Doszliśmy do wniosku, że degradacja środowiska nie jest spowodowana między innymi globalizacją i ryzykiem geopolitycznym w RPA, ale także innymi sugestiami politycznymi

How to improve research capacity strengthening efforts: learning from the monitoring and evaluation of four research consortia in Africa

Recent efforts to shift the control and leadership of health research on African issues to Africa have led to increased investments for scientific research capacity strengthening (RCS) on the continent and a greater demand for accountability, value for money and demonstration of return on investment. There is limited literature on monitoring and evaluation (M&E) of RCS systems and there is a clear need to further explore whether the M&E frameworks and approaches that are currently used are fit for purpose. The M&E approaches taken by four African RCS consortia funded under the Developing Excellence in Leadership, Training and Science in Africa (DELTAS) I initiative were assessed using several methods, including a framework comparison of the M&E approaches, semi-structured interviews and facilitated discussion sessions. The findings revealed a wide range in the number of indicators used in the M&E plans of individual consortium, which were uniformly quantitative and at the output and outcome levels. Consortia revealed that additional information could have been captured to better evaluate the success of activities and measure the ripple effects of their efforts. While it is beneficial for RCS consortia to develop and implement their own M&E plans, this could be strengthened by routine engagement with funders/programme managers to further align efforts. It is also important for M&E plans to consider qualitative data capture for assessment of RCS efforts. Efforts could be further enhanced by supporting platforms for cross-consortia sharing, particularly when trying to assess more complex effects. Consortia should make sure that processes for developmental evaluation, and capturing and using the associated learning, are in place. Sharing the learning associated with M&E of RCS efforts is vital to improve future efforts. Investing and improving this aspect of RCS will help ensure tracking of progress and impact of future efforts, and ensure accountability and the return on investment. The findings are also likely applicable well beyond health research

Nutritive Quality of Hay and Silage from Natural Grazing Land in South Western Nigeria

In the tropics, inadequate nutrition caused by scarcity of forages and its low quality constitutes a major constraint to good performance of ruminant animals (Lukuyu et al. 2011). Herbage availability during the wet season often exceeds animal requirements (Chakoma et al. 1999). As the dry season sets in, the protein level of the accumulated forages drops and the fibre level increases, with an increase in lignin content while voluntary intake decreases. Due to lack of quality forage especially in the dry season, animals feeding on them tend to lose weight and their productivity will be negatively affected. In order to reduce the limitations of feeds for ruminant animals especially during dry season, there is need to develop feed conservation strategies. The use of high quality forages appears to be the most feasible option to serve this purpose. Therefore, conservation of excess forages produced in the rainy season can be utilized as supplements during the dry season to be able to alleviate poor performance of ruminant animals and will also enhance incomes of small-scale farmers. The aim of this study was to determine the suitability of conserved forages (hay and silage) from the natural grazing land as dry season supplementary feed for ruminant animals grazing in natural pastureland

The epidemiology of residual Plasmodium falciparum malaria transmission and infection burden in an African city with high coverage of multiple vector control measures.

BACKGROUND In the Tanzanian city of Dar es Salaam, high coverage of long-lasting insecticidal nets (LLINs), larvicide application (LA) and mosquito-proofed housing, was complemented with improved access to artemisinin-based combination therapy and rapid diagnostic tests by the end of 2012. METHODS Three rounds of city-wide, cluster-sampled cross-sectional surveys of malaria parasite infection status, spanning 2010 to 2012, were complemented by two series of high-resolution, longitudinal surveys of vector density. RESULTS Larvicide application using a granule formulation of Bacillus thuringiensis var. israelensis (Bti) had no effect upon either vector density (P = 0.820) or infection prevalence (P = 0.325) when managed by a private-sector contractor. Infection prevalence rebounded back to 13.8 % in 2010, compared with <2 % at the end of a previous Bti LA evaluation in 2008. Following transition to management by the Ministry of Health and Social Welfare (MoHSW), LA consistently reduced vector densities, first using the same Bti granule in early 2011 [odds ratio (OR) (95 % confidence interval (CI)) = 0.31 (0.14, 0.71), P = 0.0053] and then a pre-diluted aqueous suspension formulation from mid 2011 onwards [OR (95 % CI) = 0.15 (0.07, 0.30), P ≪ 0.000001]. While LA by MoHSW with the granule formulation was associated with reduced infection prevalence [OR (95 % CI) = 0.26 (0.12, 0.56), P = 0.00040], subsequent liquid suspension use, following a mass distribution to achieve universal coverage of LLINs that reduced vector density [OR (95 % CI) = 0.72 (0.51, 1.01), P = 0.057] and prevalence [OR (95 % CI) = 0.80 (0.69, 0.91), P = 0.0013], was not associated with further prevalence reduction (P = 0.836). Sleeping inside houses with complete window screens only reduced infection risk [OR (95 % CI) = 0.71 (0.62, 0.82), P = 0.0000036] if the evenings and mornings were also spent indoors. Furthermore, infection risk was only associated with local vector density [OR (95 % CI) = 6.99 (1.12, 43.7) at one vector mosquito per trap per night, P = 0.037] among the minority (14 %) of households lacking screening. Despite attenuation of malaria transmission and immunity, 88 % of infected residents experienced no recent fever, only 0.4 % of these afebrile cases had been treated for malaria, and prevalence remained high (9.9 %) at the end of the study. CONCLUSIONS While existing vector control interventions have dramatically attenuated malaria transmission in Dar es Salaam, further scale-up and additional measures to protect against mosquito bites outdoors are desirable. Accelerated elimination of chronic human infections persisting at high prevalence will require active, population-wide campaigns with curative drugs

Towards a better future for Canadians with bipolar disorder:principles and implementation of a community-based participatory research model

The Collaborative RESearch Team to study psychosocial factors in bipolar disorder (CREST.BD) is a multidisciplinary network dedicated to advancing science and practice around psychosocial issues associated with bipolar disorder (BD), improving the care and wellness of people living with bipolar disorder, and strengthening services and supports for these individuals. CREST.BD specializes in community-based participatory research, in which research is conducted as a partnership between researchers and community members. This article describes the evolution of the CREST.BD network and CREST.BD’s commitment to community-based participatory research in bipolar disorder research. Examples of CREST.BD projects using community-based participatory research to study stigma, quality of life, psychosocial interventions, and creativity in bipolar disorder are highlighted, and opportunities and challenges of engaging in community-based participatory research in bipolar disorder specifically and the mental health field more broadly are discussed. This article demonstrates how CBPR can be used to enhance the relevance of research practices and products through community engagement, and how community-based participatory research can enrich knowledge exchange and mobilization

The H3ABioNet helpdesk: an online bioinformatics resource, enhancing Africa’s capacity for genomics research

Abstract Background Currently, formal mechanisms for bioinformatics support are limited. The H3Africa Bioinformatics Network has implemented a public and freely available Helpdesk (HD), which provides generic bioinformatics support to researchers through an online ticketing platform. The following article reports on the H3ABioNet HD (H3A-HD)‘s development, outlining its design, management, usage and evaluation framework, as well as the lessons learned through implementation. Results The H3A-HD evaluated using automatically generated usage logs, user feedback and qualitative ticket evaluation. Evaluation revealed that communication methods, ticketing strategies and the technical platforms used are some of the primary factors which may influence the effectivity of HD. Conclusion To continuously improve the H3A-HD services, the resource should be regularly monitored and evaluated. The H3A-HD design, implementation and evaluation framework could be easily adapted for use by interested stakeholders within the Bioinformatics community and beyond
