Enhancing democracy and good governance; a curriculum proposal for information/knowledge management professionals (IKMPs) in the SCECSAL region.
This paper seeks to advance the case for designing an information and knowledge management curriculum (IKMC) to produce information and knowledge management professionals (IKMPs) in the Standing Conference of Eastern, Central and Southern Africa Library and Information Associations (SCECSAL) region. It highlights challenges and solutions and proposes a model IKMC. A version of this paper was presented at the XIXth Standing Conference of Eastern, Central and Southern Africa Library and Information Associations (SCECSAL) 2010.Purpose – This paper seeks to advance the case for designing an information and knowledge management curriculum (IKMC) to produce information and knowledge management professionals (IKMPs) in the Standing Conference of Eastern, Central and Southern Africa Library and Information Associations (SCECSAL) region. It highlights challenges and solutions and proposes a model IKMC.
Design/methodology/approach – The paper is based on the analysis of literature on Library and Information Science (LIS) curriculum design, implementation and review; research findings by renowned LIS curriculum experts; discussions and sharing experiences with colleagues in LIS education institutions – Eastern African School of Library and Information Science and LIS departments at the Uganda Christian University and Kyambogo University in addition to the author’s research and publications on curriculum design and management.
Findings – The paper posits that the SCECSAL region is already in the Information and Knowledge Society (IKS) and that appropriate information and knowledge (IK) are pre-requisites to the promotion and sustainability of democracy and good governance (Gg). It emphasises that information and knowledge management (IKM) are the corner stones of the IKS, because they constitute the framework of theory and competencies vital in managing information and knowledge. Furthermore, effective IKM is the pillar of producing the IKMPs themselves, a product of appropriate and well managed IKMC. The paper proposes an IKMC Model capable of producing IKMPs in the SCECSAL region.
Originality/value – The proposed curriculum model should be the framework to be adopted by the LIS education and training institutions in the SCECSAL region to produce IKMPs with theory and competencies to manage the IKS towards enhancing democracy and Gg
A method for achieving reciprocity of funding in community-based participatory research
BACKGROUND: The St. Louis Komen Project was conceived to address disparities in breast cancer treatment and outcomes between African-American and White women in St. Louis, Missouri. Our goal was to apportion tasks and funding through a process to which all researcher partners had input and to which all could agree, thus eliminating institutionalized inequalities. METHODS: This paper describes the collaborative process and resulting division of responsibilities, determination of costs, and ultimate allocation of funds and resources, as well as the documentation employed to achieve funding reciprocity and equal accountability. RESULTS: Both communication and documentation are critical. Although the Memoranda of Understanding employed are not a panacea, they codify roles and expectations and promote trust. The process of developing financial transparency set the tone for subsequent steps in the research process. CONCLUSIONS: The exhaustive planning process and project-specific procedures developed by its partners have helped the project foster reciprocity, facilitate participation, and equitably distribute resources
Perceptions and acceptability of piloted Taenia solium control and elimination interventions in two endemic communities in eastern Zambia
Infections with Taenia solium cause significant public health and economic losses worldwide. Despite effective control tools, long‐term sustained control/elimination of the parasite has not been demonstrated to date. Success of intervention programs is dependent on their acceptability to local communities. Focus group discussions (FGDs) and questionnaires (QS) were conducted in two study communities in eastern Zambia to assess local perceptions and acceptance of two piloted intervention strategies: one targeting pigs only (‘control’ study arm), and one integrated human‐ and pig‐based (‘elimination’) strategy. QS (n = 227) captured data regarding participation in project activities, knowledge and perceptions of T. solium and of the interventional drugs used in the study. FGDs (n = 18) discussed perceived advantages and disadvantages of the interventions and of the project's delivery and value. QS data revealed 67% of respondents participated in at least one educational activity, and 80% correctly identified at least one disease targeted by the education. All elimination study arm respondents (n = 113) had taken the human treatment, and 98% intended to do so next time. Most (70%) indicated willingness to pay for future treatments (median 0.20 USD per dose). Of pig‐owning respondents, 11/12 (92%) had allowed their pigs to be treated/vaccinated and all intended to do so again next time. Four pig owners indicated willingness to pay 0.10–0.50 USD per dose of treatment or vaccine. FGD feedback revealed positive perceptions of interventions; people reported improved health in themselves and their pigs, and fewer cysticerci in pork. Latrine use, hand washing, meat inspection and proper cooking of pork had reportedly increased since the program's inception. Preliminary assessment indicates that the piloted intervention methods are generally acceptable to the communities. The reported willingness of many respondents to pay for the medications would contribute to the feasibility of long‐term, government‐led T. solium intervention programs in future
The response of the ITCZ to extratropical thermal forcing: Idealized slab-ocean experiments with a GCM
Using a comprehensive atmospheric GCM coupled to a slab mixed layer ocean, experiments are performed to study the mechanism by which displacements of the intertropical convergence zone (ITCZ) are forced from the extratropics. The northern extratropics are cooled and the southern extratropics are warmed by an imposed cross-equatorial flux beneath the mixed layer, forcing a southward shift in the ITCZ. The ITCZ displacement can be understood in terms of the degree of compensation between the imposed oceanic flux and the resulting response in the atmospheric energy transport in the tropics. The magnitude of the ITCZ displacement is very sensitive to a parameter in the convection scheme that limits the entrainment into convective plumes. The change in the convection scheme affects the extratropical-tropical interactions in the model primarily by modifying the cloud response. The results raise the possibility that the response of tropical precipitation to extratropical thermal forcing, important for a variety of problems in climate dynamics (such as the response of the tropics to the Northern Hemisphere ice sheets during glacial maxima or to variations in the Atlantic meridional overturning circulation), may be strongly dependent on cloud feedback. The model configuration described here is suggested as a useful benchmark helping to quantify extratropical-tropical interactions in atmospheric models.open988
Sensitivity of Climate Change Induced by the Weakening of the Atlantic Meridional Overturning Circulation to Cloud Feedback
A variety of observational and modeling studies show that changes in the Atlantic meridional overturning circulation (AMOC) can induce rapid global-scale climate change. In particular, a substantially weakened AMOC leads to a southward shift of the intertropical convergence zone (ITCZ) in both the Atlantic and the Pacific Oceans. However, the simulated amplitudes of the AMOC-induced tropical climate change differ substantially among different models. In this paper, the sensitivity to cloud feedback of the climate response to a change in the AMOC is studied using a coupled ocean-atmosphere model [the GFDL Coupled Model, version 2.1 (CM2.1)]. Without cloud feedback, the simulated AMOC-induced climate change in this model is weakened substantially. Low-cloud feedback has a strong amplifying impact on the tropical ITCZ shift in this model, whereas the effects of high-cloud feedback are weaker. It is concluded that cloud feedback is an important contributor to the uncertainty in the global response to AMOC changes.open9
Burden of sickle cell trait and disease in the Uganda Sickle Surveillance Study (US3): a cross-sectional study
Background Sickle cell disease contributes substantially to mortality in children younger than 5 years in sub-Saharan
Africa. In Uganda, 20 000 babies per year are thought to be born with sickle cell disease, but accurate data are not
available. We did the cross-sectional Uganda Sickle Surveillance Study to assess the burden of disease.
Methods The primary objective of the study was to calculate prevalence of sickle cell trait and disease. We obtained
punch samples from dried blood spots routinely collected from HIV-exposed infants in ten regions and 112 districts
across Uganda for the national Early Infant Diagnosis programme. Haemoglobin electrophoresis by isoelectric
focusing was done on all samples to identify those from babies with sickle trait or disease.
Findings Between February, 2014, and March, 2015, 99 243 dried blood spots were analysed and results were available
for 97 631. The overall number of children with sickle cell trait was 12 979 (13·3%) and with disease was 716 (0·7%).
Sickle cell numbers ranged from 631 (4·6%) for trait and 23 (0·2%) for disease of 13 649 in the South Western region
to 1306 (19·8%) for trait and 96 (1·5%) for disease of 6581 in the East Central region. Sickle cell trait was seen in all
districts. The lowest prevalence was less than 3·0% in two districts. Eight districts had prevalence greater than 20·0%,
with the highest being 23·9%. Sickle cell disease was less common in children older than 12 months or who were
HIV positive, which is consistent with comorbidity and early mortality.
Interpretation Prevalence of sickle cell trait and disease were high in Uganda, with notable variation between regions
and districts. The data will help to inform national strategies for sickle cell disease, including neonatal screening
Comparative RNA editing in autistic and neurotypical cerebella
Adenosine-to-inosine (A-to-I) RNA editing is a neurodevelopmentally regulated epigenetic modification shown to modulate complex behavior in animals. Little is known about human A-to-I editing, but it is thought to constitute one of many molecular mechanisms connecting environmental stimuli and behavioral outputs. Thus, comprehensive exploration of A-to-I RNA editing in human brains may shed light on gene–environment interactions underlying complex behavior in health and disease. Synaptic function is a main target of A-to-I editing, which can selectively recode key amino acids in synaptic genes, directly altering synaptic strength and duration in response to environmental signals. Here, we performed a high-resolution survey of synaptic A-to-I RNA editing in a human population, and examined how it varies in autism, a neurodevelopmental disorder in which synaptic abnormalities are a common finding. Using ultra-deep (>1000 × ) sequencing, we quantified the levels of A-to-I editing of 10 synaptic genes in postmortem cerebella from 14 neurotypical and 11 autistic individuals. A high dynamic range of editing levels was detected across individuals and editing sites, from 99.6% to below detection limits. In most sites, the extreme ends of the population editing distributions were individuals with autism. Editing was correlated with isoform usage, clusters of correlated sites were identified, and differential editing patterns examined. Finally, a dysfunctional form of the editing enzyme adenosine deaminase acting on RNA B1 was found more commonly in postmortem cerebella from individuals with autism. These results provide a population-level, high-resolution view of A-to-I RNA editing in human cerebella and suggest that A-to-I editing of synaptic genes may be informative for assessing the epigenetic risk for autism.Nancy Lurie Marks Family FoundationF.

Experience-Dependent, Layer-Specific Development of Divergent Thalamocortical Connectivity
The main input to primary sensory cortex is via thalamocortical (TC) axons that form the greatest number of synapses in layer 4, but also synapse onto neurons in layer 6. The development of the TC input to layer 4 has been widely studied, but less is known about the devel-opment of the layer 6 input. Here, we show that, in neonates, the input to layer 6 is as strong as that to layer 4. Throughout the first postnatal week, there is an experience-dependent strengthening specific to layer 4, which correlates with the ability of synapses in layer 4, but not in layer 6, to undergo long-term potentiation (LTP). This strengthening consists of an increase in axon branching and the divergence of connectivity in layer 4 without a change in the strength of individual connections. We propose that experience-driven LTP stabilizes transient TC synapses in layer 4 to increase strength and divergence specifically in layer 4 over layer 6
