    In this article, we consider how an atmospheric attunement to place enables new ways of writing place. Specifically, we draw on fieldwork conducted in Johannesburg and reflect on the outcome of a remote, collective writing process pursued during months of lockdown, when our attention was dominated by talk of air and virality. We think about how our fieldwork provided us with an unsettling preview of the atmospheric anxieties to come, of a time when the very idea of the urban harboured an unseen and largely uncalibrated threat. Having developed a digital StoryMap as a way to host our written reflections, we also assess the importance of our cross-disciplinary method, especially when it comes to sensing and responding to these atmospheric circulations in less anxious, more critical terms

    The CuAAC ‘click’ reaction was used to couple alkyne-functionalized lanthanide-DOTA complexes to a range of fluorescent antennae. Screening of the antenna components was aided by comparison of the luminescent output of the resultant sensors using data normalized to account for reaction conversion as assessed by IR. A maximum 82-fold enhanced signal:background luminescence output was achieved using a Eu(III)-DOTA complex coupled to a coumarin-azide, in a reaction which is specific to the presence of copper(I). This optimized complex provides a new lead design for lanthanide-DOTA complexes which can act as irreversible ‘turn-on’ catalytic sensors for the detection of ligand-bound copper(I)

    Mixed blessings: a qualitative exploration of mothers’ experience of child care and feeding in the rapidly urbanizing city of Addis Ababa, Ethiopia

    Many studies have drawn attention to the vital role mothers have in safeguarding the health and nutritional wellbeing of their children. However, little is known about mothers’ experiences and the challenges they face in fulfilling this role in rapidly urbanizing cities in Africa. This study aims to explore child care and feeding practices of mothers with children under five years of age in Addis Ababa, Ethiopia. This qualitative study was conducted using a semi-structured interview guide. A total of thirty-six interviews were conducted with purposively selected participants. All interviews were audio recorded, transcribed verbatim and translated for analysis. We used a thematic analysis approach, which was guided by a resilience framework. The findings are presented as three major themes. 1) ‘Mixed blessings-balancing motherhood’s expectations’. While mothers identified positively with the social recognition and sense of fulfillment of being a ‘good mother’, they were ambivalent/torn about earning the necessary income from outside work and fulfilling their duties at home. 2) ‘Instabilities due to rampant urban sprawl’. While women expressed a keen desire to balance work and motherhood, the disintegrating social capital, due to large in-migration, market fluctuations and abrupt/forced resettlements to new housing units had left mothers without support for childcare, stressed and exhausted. 3) ‘Anchored by faith: a source of resilience to cope with adversities’. In the face of the multiple adversities, mothers cited their strong faith as their most reliable foundation for their resilience. In summary, the societal and environmental changes accompanying the rapid urbanization in low income settings makes combining child care and working outside the home very challenging for mothers. As a result they suffer from fatigue and feelings of isolation. Efforts to improve child feeding and care in urban low-income settings need to consider context appropriate strategies that support mothers with small children

    Social Stratification, Diet Diversity and Malnutrition among Preschoolers: A Survey of Addis Ababa, Ethiopia

    In Sub-Saharan Africa, being overweight in childhood is rapidly rising while stunting is still remaining at unacceptable levels. A key contributor to this double burden of malnutrition is dietary changes associated with nutrition transition. Although the importance of socio-economic drivers is known, there is limited knowledge about their stratification and relative importance to diet and to different forms of malnutrition. The aim of this study was to assess diet diversity and malnutrition in preschoolers and evaluate the relative importance of socioeconomic resources. Households with children under five (5467) were enrolled using a multi-stage sampling procedure. Standardized tools and procedures were used to collect data on diet, anthropometry and socio-economic factors. Multivariable analysis with cluster adjustment was performed. The prevalence of stunting was 19.6% (18.5–20.6), wasting 3.2% (2.8–3.7), and overweight/obesity 11.4% (10.6–12.2). Stunting, overweight, wasting and limited diet diversity was present in all social strata. Low maternal education was associated with an increased risk of stunting (Adjusted odds ratio (AOR): 1.8; 1.4–2.2), limited diet diversity (AOR: 0.33; 0.26–0.42) and reduced odds of being overweight (AOR: 0.61; 0.44–0.84). Preschoolers in Addis Ababa have limited quality diets and suffer from both under- and over-nutrition. Maternal education was an important explanatory factor for stunting and being overweight. Interventions that promote diet quality for the undernourished whilst also addressing the burgeoning problem of being overweight are needed

    What influences urban mothers’ decisions on what to feed their children aged under five—the case of addis ababa, Ethiopia

    Get PDF
    Mothers carry the prime responsibility for childcare and feeding in low-income countries. Understanding their experiences in providing food for their children is paramount to informing efforts to improve the nutritional status of children. Such information is lacking in Sub-Saharan Africa. To understand what influences urban mothers’ food acquisition and their motivations for selecting food for their children, 36 in-depth interviews were carried out with mothers having children under five years of age. Interviews were conducted in the local language, audio-recorded, transcribed, and translated into English. Data were analyzed using thematic analysis which led to the identification of four major themes: mothers give-in to a child-driven diet; quick-fix versus the privilege of planning; keen awareness on food safety, nutrition, and diet diversity; and social, familial, and cultural influences. The findings indicate that child feeding practices are influenced by interlinked social and environmental factors. Hence, nutrition education campaigns should focus on targeting not only families but also their children. Attention should also be given to food safety regulations, as well as to the much-needed support of mothers who are struggling to ensure their children’s survival in low-income countries

    Three-arm, randomized, phase 2 study of carboplatin and paclitaxel in combination with cetuximab, cixutumumab, or both for advanced non-small cell lung cancer (NSCLC) patients who will not receive bevacizumab-based therapy: An Eastern Cooperative Oncology Group (ECOG) study (E4508)

    BACKGROUND: Preclinical evidence supports the clinical investigation of inhibitors to the insulin-like growth factor receptor (IGFR) and the epidermal growth factor receptor (EGFR) either alone or in combination as treatment for patients with non-small cell lung cancer (NSCLC). METHODS: Patients with chemotherapy-naïve, advanced NSCLC who had an Eastern Cooperative Oncology Group performance status of 0 or 1 were eligible. Patients were randomized to receive carboplatin intravenously at an area under the plasma drug concentration-time curve of 6.0 plus paclitaxel 200 mg/m(2) intravenously on day 1 every 3 weeks combined with either intravenous cetuximab weekly (arm A), intravenous cixutumumab every 2 weeks (arm B), or both (arm C). Patients who had nonprogessing disease after 12 weeks of therapy were permitted to continue on maintenance antibody therapy until they developed progressive disease. The primary endpoint was progression-free survival (PFS). The study design required 180 eligible patients and had 88% power to detect a 60% increase in median PFS for either comparison (arm A vs arm C or arm B vs arm C) using the log-rank test. RESULTS: From September 2009 to December 2010, 140 patients were accrued. The study was closed to accrual early because of an excessive number of grade 5 events reported on arms A and C. Thirteen patients died during treatment (6 patients on arm A, 2 patients on arm B, and 5 patients on arm C), including 9 within approximately 1 month of starting therapy. The estimated median PFS for arms A, B, and C were similar at 3.4 months, 4.2 months, and 4 months, respectively. CONCLUSIONS: On the basis of the apparent lack of efficacy and excessive premature deaths, the current results do not support the continued investigation of carboplatin, paclitaxel, and cixutumumab either alone or in combination with cetuximab for patients with advanced NSCLC

    Get PDF
    This article charts the progress of CenUSA Bioenergy, a USDA-NIFA-AFRI coordinated agricultural project focused on the North Central region of the US. CenUSA’s vision is to develop a regional system for producing fuels and other products from perennial grass crops grown on marginally productive land or land that is otherwise unsuitable for annual cropping. This article focuses on contributions CenUSA has made to nine primary systems needed to make this vision a reality: feedstock improvement; feedstock production on marginal land; feedstock logistics; modeling system performance; feedstock conversion into biofuels and other products; marketing; health and safety; education, and outreach. The final section, Future Perspectives, sets forth a roadmap of additional research, technology development and education required to realize commercialization

    Prenatal reflective functioning in primiparous women with a high-risk profile

    Get PDF
    The concept of maternal reflective functioning (RF) has been gaining increasing interest as a possible intermediate mechanism in associations between a wide range of psychosocial risk factors and poor child outcomes. The purpose of the present study was to determine which psychosocial risk factors are linked to prenatal RF in a high-risk (HR) group of primiparous women. Differences in prenatal RF between the HR group and a low-risk (LR) control group also were examined. The sample consisted of 162 women (M = 22.22 years, SD = 2.39; 83 classified as HR). RF was coded from the Pregnancy Interview (A. Slade, 2007a). Risk status was assessed by means of the Mini-International Neuropsychiatric Interview-plus (M.I.N.I.-plus; D.V. Sheehan et al., 1997) and several questionnaires. HR women demonstrated significantly lower RF quality than did the LR group. Regression analyses indicated that maternal education, size of social support network, and substance use during pregnancy were the strongest predictors of prenatal RF for the HR group. The results suggest that maternal RF potentially could be an important target for those prevention and intervention programs that aim to reduce adverse psychosocial development in offspring of HR mothers
