    The changes in stream discharge extremes due to temperature and seasonality are key metrics in assessing the effects of climate change on the hydrological cycle. While scaling is commonly applied to temperature and precipitation due to the physical connections between temperature and moisture (i.e., Clausius–Clapeyron), the scaling rate of stream discharge extremes to air and dewpoint temperatures has not been evaluated. To address this challenge, we assess the scaling rates between stream discharge and air temperature and between stream discharge and dewpoint temperature in Utah using a well-designed statistical framework. While there are deviations from the Clausius–Clapeyron (CC) relationship in Utah using discharge data based on stream gauges and gridded climate data, we identify positive scaling rates of extreme discharge to temperatures across most of the state. Further diagnosis of extreme discharge events reveals that regional factors combined with topography are responsible for the marked seasonality of scaling, with most areas of Utah driven by spring snowmelt tied to high temperatures. The exception is far southwestern areas, being largely driven by winter rain-on-snow events. Our research highlights a measurable portion of stream discharge extremes associated with higher temperatures and dewpoints, suggesting that climate change could facilitate more extreme discharge events despite reductions to mean flows

    This work is licensed under a Creative Commons Attribution 4.0 International License.This contribution to the collection of articles on “African Cultural Models” considers the topic of well-being. Reflecting modern individualist selfways of North American and European worlds, normative conceptions of well-being in hegemonic psychological science tend to valorize self-acceptance, personal growth, and autonomy. In contrast, given the embedded interdependence of everyday life in many West African worlds, one can hypothesize that cultural models of well-being in many Ghanaian settings will place greater emphasis on sustainability-oriented themes of material sufficiency and successful navigation of normative obligations. To explore this hypothesis, we interviewed local cultural experts who function as custodians of religion and an important source of support for well-being in many Ghanaian settings. We asked participants to identify and explain models of well-being implicit in four Ghanaian languages (Akan, Dagbani, Ewe, and Ga). Participants were 19 men and 15 women (age range 32–92 years; Mean = 59.83; SD: 14.01). Results reveal some features of local models, including good health and positive affective states, that appear to resonate with standard understandings of well-being in hegemonic psychological science. However, results also provide evidence for other features of local models – specifically, good living (including moral living, material success, and proper relationality) and peace of mind – associated with a sustainability or maintenance orientation to well-being.Volkswagen Foundation, Germany (94667

    Conception and experience of well-being in two Ghanaian samples: Implications for Positive Psychology

    We conducted two studies to explore Ghanaian understandings of well-being through a situation sampling method in which participants described situations that increased and decreased their well-being. Participants in Study 1 were 80 community members (Mean Age = 41.962; SD=13.900; 40 women, 40 men) who responded in the context of interviews through the medium of local languages. Coding analyses revealed that these situation descriptions emphasized sustainability-oriented themes of materiality (tangible support, economic hardship) and peace of mind (presence or absence of worry or strife) with greater frequency than growth-oriented themes of psychologization (growth, meaning, achievement) and affect (happiness, sadness). Participants in Study 2 were 125 students (Mean Age = 21.592; SD=2.759; 68 women, 57 men) at three universities in Ghana who responded via questionnaire in the medium of English. In contrast to the community sample, coding analyses revealed that the students’ situations emphasized growth-oriented themes of affect and psychologization with greater frequency than sustainability-oriented themes of materiality and peace of mind. We interpret these results within a theoretical framework that emphasizes the cultural-psychological foundations of well-being, and we consider implications for hegemonic perspectives of positive psychology

    Prevalence of Overweight and Obesity among Students in the Kumasi Metropolis

    The aim was to determine the prevalence of obesity and overweight among students in the Kumasi metropolis. In a descriptive cross-sectional study, 500 students aged 10 to 20 years were examined from two junior high schools selected by multistage sampling technique and three randomly selected senior high schools. Height and weight were measured in all participants and the body mass index (BMI) of each individual was calculated. Body mass index classes were calculated according to the International Obesity Task Force standards. Out of the 500 students, 290 (58.00%) were males and 210 (42.00%) were females. The prevalence of underweight, normal weight, overweight, and obesity was 7.40%, 79.60%, 12.20%, and 0.80%, respectively. Overweight was more prevalent among students than obesity. There is therefore the need to establish effective public health promotion campaigns among students in order to curtail future implications on health

    Improving the quality of life of pregnant women using the intermittent preventive treatment with sulphadoxine pyrimethamine (IPT-SP): Experiences from Dangme West District, Ghana

    The impact of intermittent preventive treatment (IPTp) as a strategy for malaria control and the extent to which it improves the quality of life of pregnant women and outcome of pregnancy in the Dangme West district, Ghana was assessed by conducting a cross-sectional descriptive study. One hundred (100) pregnant women were selected by multi-stage cluster sampling from 21 communities. The study utilized both qualitative and quantitative methods in assessing the impact of IPTp. In addition to the above, data was also collected through desk top reviews of HCFs’ records, the district’s health annual reports, published and unpublished literature, textbooks, etc. IPTp strategy is doing very well as a strategy for malaria control and management in pregnancy in the district. The outcome of pregnancy has improved significantly but due to late assumption of antenatal care many women do not get the requisite dosage to realise the full potential of the IPTp therapy. Community participation should be enhanced to realise the full potential of the IPT-SP strategy

    Virological Characterization of Dual HIV-1/HIV-2 Seropositivity and Infections in Southern Ghana.

    SUMMARY BACKGROUND: Dual HIV-1/HIV-2 seropositivity (dual seropositivity) is common in West African countries including Ghana. The diagnosis of dual HIV-1/HIV-2 infections is however complicated as HIV-2 DNA is more often not detected in dual seropositive individuals. OBJECTIVES: To detect the presence of HIV-1 and HIV-2 pro-viral DNA in dual seropositives and to determine the correlation between HIV-2 antibody titers and presence of HIV-2 DNA. The growth kinetics of HIV-1 and HIV-2 in vitro were also determined using plasma and lymphocyte cultures. DESIGN: Cross-sectional study SETTING: Urban and semi-rural HIV/AIDS clinics PARTICIPANTS: 13 dual HIV-1/HIV-2 seropositives from Agomanya and Accra RESULTS: HIV-1 DNA was detected in uncultured peripheral blood mononuclear cells of all 13 patients but HIV-2 DNA in 4 (30.8%). HIV-2 antibody titres were not useful in determining the presence or absence of HIV-2 DNA (P=0.28, Mann-Whitney U test). HIV-2 specific antibody was detected in 12 of the 13 dual seropositives by peptide-inhibition, the only patient with an Innolia gp36 band rating of 1+ was shown not to be reactive. HIV-2 grew efficiently in the presence or HIV-1 in vitro. CONCLUSION: HIV-2 DNA may not be detected in all dual seropositives thus not all of such patients may need drugs effective against HIV-2. Peptide based assays will be useful for correctly diagnosing dual seropositivity. Since HIV-2 may grow efficiently in the presence of HIV-1 and no commercial HIV-2 HIV RNA tests are available, dual seropositives on HAART need to be monitored to determine if a lack of immune restoration may correspond to an efficient suppression of HIV-1 RNA levels
