Social Underdevelopment In Sub-saharan Africa

For the past thirty years Africa has produced a more noticeably inferior reserve of human capital than other developing regions. This is puzzling because at the inception of independence, the future of Africa looked promising. However, during the 1970s both the political and economic situation in Africa began to deteriorate, and since 1980, the aggregate per capita GDP in sub-Saharan Africa has declined at almost one percent per fiscal year. Thirty-two countries are poorer now than they were twenty years ago, and sub-Saharan Africa is now the lowest-income region in the world despite the fact that during the last two decades Africa has attracted more aid per capita than other developing regions. I hypothesize that focusing primarily on economic growth as the primary means of development has undermined and deterred social development in sub-Saharan Africa. I believe that as foreign investment and debt increase, social development stagnates and even declines. I argue that because of the focus on economics and lack of focus on social and cultural considerations sustained economic growth has been devitalized in sub-Saharan Africa. For this research I employed time-series, cross-sectional regression analysis to test the relative importance of the economic development model on social development in sub-Saharan Africa. My analysis of the forty-eight countries over thirty years gives leverage to the critique of economic growth centered development policies

Collateral Estoppel

The doctrine of collateral estoppel involves the use of an old judgment in a new action to prevent the relitigation of issues resolved by that old judgment. At common law, use of the doctrine required that the party using collateral estoppel and the party against whom it was used be the same as the parties to the prior judgment. This common law requirement of mutuality has been relaxed and since the United States Supreme Court\u27s 1979 decision in ParklaneHoisery Co. v. Shore, the strict common law requirement of mutuality has all but completely vanished. In Parklane the Court sanctioned the use of collateral estoppel by a plaintiff who was a stranger to the original suit against a defendant who was party to that suit. The courts\u27 search for fair results and judicial economy in the application of the doctrine led to this application of the doctrine in circumstances in which the parties were not mutual. This note traces the un- steady course which the doctrine of collateral estoppel traveled before Parklane. The significance of the Court\u27s decision in Parklane is then analyzed. Finally, post-Parklane applications of collateral estoppel are discussed, including the effect of the use of collateral estoppel on the seventh amendment right to jury trial and its impact on substantive areas of law

Stressful Life Events and Behavior Change: A Qualitative Examination of African American Women\u27s Participation in a Weight Loss Program

We qualitatively assessed how life stressors affected African American women\u27s participation in a weight reduction program. A sample of 9 women, who completed a behavioral lifestyle intervention, participated in individual, structured, in-depth interviews. Life stressors, ranging from personal illness to changes in employment status, had varied effects on participation. Some women coped with life stressors by using them as a motivational tool to improve their own health, while others reported limited ability to devote time to attend meetings or engage in the prescribed lifestyle changes due to life stressors. A critical key to improving weight loss outcomes for African American women may be using intervention strategies that teach positive coping skills to alter maladaptive responses to life stressors

Emergency Preparedness Training for Hospital Nursing Staff, New York City, 2012–2016

Purpose Many nurses are trained inadequately in emergency preparedness (EP), preventing them from effectively executing response roles during disasters, such as chemical, biological, radiological, nuclear, and explosive (CBRNE) events. Nurses also indicate lacking confidence in their abilities to perform EP activities. The purpose of this article is to describe the phased development of, and delivery strategies for, a CBRNE curriculum to enhance EP among nursing professionals. The New York City (NYC) Department of Health and Mental Hygiene (DOHMH) and the National Center for Disaster Preparedness at Columbia University's Earth Institute led the initiative. Methods Curriculum development included four phases. In Phases I and II, nursing staff at 20 participating NYC hospitals conducted 7,177 surveys and participated in 20 focus groups to identify training gaps in EP. In Phase III, investigators developed and later refined the CBRNE curriculum based on gaps identified. In Phase IV, 22 nurse educators (representing 7 of the original 20 participating hospitals) completed train‐the‐trainer sessions. Of these nurse educators, three were evaluated on their ability to train other nurses using the curriculum, which investigators finalized. Findings The CBRNE curriculum included six modules, a just‐in‐time training, and an online annual refresher course that addressed EP gaps identified in surveys and focus groups. Among the 11 nurses who were trained by three nurse educators during a pilot training, participant knowledge of CBRNE events and response roles increased from an average of 54% (range 45%–75%) on the pre‐test to 89% (range 80%–90%) on the posttest. Conclusions By participating in nursing CBRNE training, nurses increased their knowledge of and preparedness to respond to disasters. The train‐the‐trainer curriculum is easily adaptable to meet the needs of other healthcare settings. Clinical Relevance The CBRNE curriculum can be used to train nurses to better prepare for and more effectively respond to disasters

Opioid medication use and blood DNA methylation:epigenome-wide association meta-analysis

Aim: To identify differential methylation related to prescribed opioid use. Methods: This study examined whether blood DNA methylation, measured using Illumina arrays, differs by recent opioid medication use in four population-based cohorts. We meta-analyzed results (282 users; 10,560 nonusers) using inverse-variance weighting. Results: Differential methylation (false discovery rate \u3c0.05) was observed at six CpGs annotated to the following genes: KIAA0226, CPLX2, TDRP, RNF38, TTC23 and GPR179. Integrative epigenomic analyses linked implicated loci to regulatory elements in blood and/or brain. Additionally, 74 CpGs were differentially methylated in males or females. Methylation at significant CpGs correlated with gene expression in blood and/or brain. Conclusion: This study identified DNA methylation related to opioid medication use in general populations. The results could inform the development of blood methylation biomarkers of opioid use

The Effect of Enriched Environment on the Outcome of Traumatic Brain Injury; A Behavioral, Proteomics, and Histological Study

De novo hippocampal neurogenesis contributes to functional recovery following traumatic brain injury (TBI). Enriched environment (EEN) can improve the outcome of TBI by positively affecting neurogenesis. Blast induced traumatic brain injury (bTBI) characterized by memory impairment and increased anxiety levels, is a leading cause of chronic disability among soldiers. Using a rodent model of bTBI we asked: (a) whether long-term exposure to EEN after injury can ameliorate behavioral abnormalities and (b) what the effects of EEN are at the molecular and cellular levels and on de novo neurogenesis. We found that housing injured animals in EEN resulted in significantly improved spatial memory while animals in normal housing (NH) showed persistent memory impairment. VEGF and Tau protein but not Interleukin-6 (IL-6) levels were normalized in the dorsal hippocampus (DHC) of EEN rats while all three markers remained elevated in NH rats. Interestingly, after peaking at 6 weeks post-injury, anxiety returned to normal levels at 2 months independent of housing conditions. Housing animals in EEN had no significant effect on VEGF and Tau protein levels in the ventral hippocampus (VHC) and the amygdala (AD). We also found that EEN reduced IL-6 and IFNγ levels in the VHC; these markers remained elevated following NH. We observed an increase in GFAP and DCX immunoreactivities in the VHC of NH animals at 2 months post-injury. Conversely, injured animals housed in EEN showed no increase in GFAP or DCX immunoreactivity in their VHC. In summary, long-term exposure of injured animals to EEN appears to play a positive role in the restoration of memory functions but not on anxiety, which returned to normal levels after a significant period of time. Cellular and molecular changes in response to EEN appear to be a part of neurogenesis-independent as well as dependent recovery processes triggered by bTBI

High Resolution Observations of Drop Size Distribution for GPM Ground Validation

During the Mid-latitude Continental Convective Cloud Experiment (MC3E), NASA's GPM GV Disdrometer and Radar Observations of Precipitation (DROP) Facility deployed an array of disdrometers and rain gauges in northern Oklahoma to sample, with high resolution, the drop size distribution for use in development of precipitation retrieval algorithms for the GPM core satellites. The DROP Facility instruments deployed during MC3E consisted of 16 autonomous Parsivel units, 5 two-dimensional video disdrometers (2dvds), a vertically pointing K band radar, and 32 tipping bucket rain gauges. There were several rainfall events during MC3E in which rain drops exceeding 6 mm in diameter were recorded. The disdrometer array revealed large rain drops with diameters exceeding 6 mm and 8 mm during two separate stratiform and convective rainfall events, respectively. The NPOL radar, which was scanning in high resolution RHI mode (every 40 sec) over the disdrometer array during the stratiform event, indicated a 1 km thick bright band with a differential reflectivity column of 2-3 dB extending below the melting layer to the surface where the large drops were recorded by the 2dvds. These large drops are important for GPM since they can have a great impact upon satellite precipitation retrieval, especially near the ground and below heavy convective rainfall cores where satellites have had problems depicting the rainfall

Spatial housing economics: a survey

This introduction to the Virtual Special Issue surveys the development of spatial housing economics from its roots in neo-classical theory, through more recent developments in social interactions modelling, and touching on the role of institutions, path dependence and economic history. The survey also points to some of the more promising future directions for the subject that are beginning to appear in the literature. The survey covers elements hedonic models, spatial econometrics, neighbourhood models, housing market areas, housing supply, models of segregation, migration, housing tenure, sub-national house price modelling including the so-called ripple effect, and agent-based models. Possible future directions are set in the context of a selection of recent papers that have appeared in Urban Studies. Nevertheless, there are still important gaps in the literature that merit further attention, arising at least partly from emerging policy problems. These include more research on housing and biodiversity, the relationship between housing and civil unrest, the effects of changing age distributions - notably housing for the elderly - and the impact of different international institutional structures. Methodologically, developments in Big Data provide an exciting framework for future work

This thing called communitarianism: A critical review of Matolino's Personhood in African Philosophy

The subject of personal identity has received substantial treatment in contemporary African philosophy. Importantly, the dominant approach to personal identity is communitarian. Bernard Matolino's new book Personhood in African Philosophy enters into this discussion by way of contesting some of the assumptions underlying communitarian approaches. His own critical assessment leads him to what I believe is an unprecedented objection in the literature; the conclusion that communitarian philosophers are involved in a category mistake when framing the question and articulating the notion of personhood. I intend to present a brief summary of the chapters of the book and reflect on some of the main philosophical issues that the book provokes, noting what I take to be refreshing insights that Matolino brings to the discussion while also engaging critically with the ones I find most contentious. In particular, I briefly assess Matolino's implicit suggestion that an Akan inspired quasi-physicalist account of mind avoids the mind-body interaction problem; I object to the category mistake charge on behalf of communitarians; and lastly, I raise questions about, and propose ways Matolino can refine, his proposal concerning a new way of thinking about personhood, which goes under the rubric of Limited Communitarianism.IS

Analysis of oral cancer epidemiology in the US reveals state-specific trends: implications for oral cancer prevention

Background: Downward trends have been observed in oral cancer incidence and mortality in the US over the past 30 years; however, these declines are not uniform within this population. Several studies have now demonstrated an increase in the incidence and mortality from oral cancers among certain demographic groups, which may have resulted from increased risks or risk behaviors. This study examines the underlying data that comprise these trends, to identify specific populations that may be at greater risk for morbidity and mortality from oral cancers. Methods: Oral cancer incidence and mortality data analyzed for this study were generated using the National Cancer Institute\u27s Surveillance, Epidemiology and End Results (SEER) program. Results: While oral cancer incidence and mortality rates have been declining over the past thirty years, these declines have reversed in the past five years among some demographic groups, including black females and white males. Sorting of these data by state revealed that eight states exhibited increasing rates of oral cancer deaths, Nevada, North Carolina, Iowa, Ohio, Maine, Idaho, North Dakota, and Wyoming, in stark contrast to the national downward trend. Furthermore, a detailed analysis of data from these states revealed increasing rates of oral cancer among older white males, also contrary to the overall trends observed at the national level. Conclusion: These results signify that, despite the declining long-term trends in oral cancer incidence and mortality nationally, localized geographic areas exist where the incidence and mortality from oral cancers have been increasing. These areas represent sites where public health education and prevention efforts may be focused to target these specific populations in an effort to improve health outcomes and reduce disparities within these populations
