Language Use in the Portrayal of both Women and Men in HIV/AIDS Public Sensitization Texts in the Tanzanian Mass Media

This research paper aimed at exploring how women and men are portrayed in HIV/AIDS public sensitization texts in the Tanzanian mass media. The research was carried out in Dodoma region, Dodoma municipality in central Tanzania. The data was collected in both print and electronic media. Since it is a qualitative research, I analyzed the concepts by describing the essential and core concepts; interpretation of data whereby the issue is studied and described within the broader context to add meaning to the data. In order to explore the social construction of gender roles in language use, I relied on the Feminism Theory (FT) and Critical Discourse Analysis (CDA), which contends that there is a close relationship between language and power and that language can lead to imbalance power relations.The study reveals that women and men are portrayed differently. Men are shown as active; they are the ones who matter, while women are shown as passive or second class human beings. In the anti-HIV/AIDS discourse, men are portrayed as the ones who are main users of condoms while women are depicted as passive objects. This means that, women have no power over the act of safe sex since they depend on men who decide on whether to use condoms or not.

The Glasgow consensus on the delineation between pesticide emission inventory and impact assessment for LCA

Purpose: Pesticides are applied to agricultural fields in order to optimise crop yield and their global use is substantial. Their consideration in Life cycle assessment (LCA) is currently affected by important inconsistencies between the emission inventory and impact assessment phases of LCA. A clear definition of the delineation between the product system model (life cycle inventory, technosphere) and the natural environment (life cycle impact assessment, ecosphere) is currently missing and could be established via consensus building. Methods: A workshop held on the 11 May 2013, in Glasgow, UK, back to back with the 23rd SETAC Europe meeting had the goal of establishing consensus and creating clear guidelines where the boundary between the emission inventory and the impact characterisation model should be set in all three spatial dimensions and time when considering application of substances to an open agricultural field or in greenhouses, and consequent emissions to the natural environment and their potential impacts. More than 30 specialists in agrifood LCI, LCIA, risk assessment, and ecotoxicology, representing industry, government, and academia from 15 countries and four continents met to discuss and reach consensus. The resulting guidelines target LCA practitioners, data (base) and characterisation method developers, and decision makers. Results and discussion: Although, the initial goal was to define recommendations concerning boundaries between technosphere and ecosphere, it became clear that these strongly depend on goal and scope of an LCA study. Instead, the focus was on defining a clear interface between LCI and LCIA, capable of supporting any goal and scope requirements while avoiding double counting or exclusion of important emission flows and their potential impacts. Consensus was reached accordingly on distinct sets of recommendations for LCI and LCIA respectively, recommending for example that buffer zones should be considered as part of the crop production system and the change in yield per ha be considered. While the spatial dimensions of the field were not fixed, the temporal boundary between dynamic LCI fate modelling and steady-state LCIA fate modelling needs to be defined. Conclusions and recommendations: For pesticides application, the inventory should report: pesticide identification, crop, mass applied of each active ingredient, application method or formulation type, presence of buffer zones (y/n), location/country, application time in days before harvest and crop growth stage during application, adherence with Good Agricultural Practice (GAP), and whether the field is considered part of the technosphere or the ecosphere. Additionally, emission fractions to defined environmental media on-field and off-field should be reported. For LCIA, the directly concerned impact categories were identified as well as a list of relevant fate and exposure processes. Next steps and future work were identified: 1) establishing default emission fractions to environmental media for integration into LCI databases, and 2) interaction among impact model developers to extend current methods with new elements/processes mentioned in the recommendations, including targeted technical workshops on “how to” model specific processes.JRC.H.8-Sustainability Assessmen

Prevalence of chronic obstructive pulmonary disease and associated factors among small-holder fish vendors along coastal areas in Tanzania

Abstract Background In Tanzania little is known about how the respiratory system of small-holder fish vendors is affected by occupational exposure to biomass smoke and other associated factors. This study assessed the prevalence of lung obstruction and associated factors among small-holder fish vendors along coastal areas in Tanzania. Methods A cross-sectional descriptive study was conducted in Bagamoyo and Kunduchi fish markets along coastal areas of Tanzania. Environmental air pollutant levels and composition were measured using a hand-held device. A standardized questionnaire was used to assess respiratory symptoms while EasyOne spirometer was used to test for lung function among small-holder fish vendors. Chronic Obstructive Pulmonary Disease (COPD) was defined as FEV1/FVC below the lower limit of normal. Data were analyzed using STATA Version 17. Descriptive statistics was performed and logistic regression analysis was used to determine factors that are associated with poor lung function presented as crude and adjusted odds ratio and their 95% confidence intervals. Results A total of 103 participants were included in the study who were predominantly males 82 (79.6%). The participants’ mean age was 35.47 (± 8.77 SD) years. The hourly average concentration levels of PM1, PM2.5, PM10, and CO exposure during fish frying were 653.6 (± 206.3 SD) μg/m3, 748.48 (± 200.6 SD) μg/m3, 798.66 (± 181.71 SD) μg/m3 and 62.6 (± 12.3 SD) ppm respectively which are higher than the WHO recommended limits. The prevalence of COPD was found to be 32.04% (95% CI 0.23–0.42). Most of the participants reported respiratory symptoms like coughing, wheezing, sputum production and breathlessness during performing their daily activities. Conclusion Findings suggest that three out of ten participants had COPD and the major environmental air pollutants (PMs and CO) concentration levels were too high, suggesting that occupational exposure to biomass smoke may be a risk factor. This calls for effective approaches to reduce exposure and prevent known acute and chronic respiratory diseases that are associated with such exposure to air pollutants. Also the study calls for follow up or cohort studies to be conducted in this area

Interventions to reduce pesticide exposure from the agricultural sector in Africa: a workshop report

Despite the fact that several cases of unsafe pesticide use among farmers in different parts of Africa have been documented, there is limited evidence of which specific interventions are effective in reducing pesticide exposure and associated risks to human health and ecology. The overall goal of the African Pesticide Intervention Project (APsent) study is to better understand ongoing research and public health activities related to interventions in Africa through the implementation of suitable target-specific situations or use contexts. A systematic review of the scientific literature on pesticide intervention studies with a focus on Africa was conducted. This was followed by a qualitative survey among stakeholders involved in pesticide research or management in the African region to learn about barriers to and promoters of successful interventions. The project was concluded with an international workshop in November 2021, where a broad range of topics relevant to occupational and environmental health risks were discussed such as acute poisoning, street pesticides, switching to alternatives, or disposal of empty pesticide containers. Key areas of improvement identified were training on pesticide usage techniques, research on the effectiveness of interventions targeted at exposure-reduction and/or behavioral changes, awareness-raising, implementation of adequate policies, and enforcement of regulations and processe
