Deep Learning Models for Health and Safety Risk Prediction in Power Infrastructure Projects

Inappropriate management of health and safety (H&S) risk in power infrastructure projects can result in occupational accidents and equipment damage. Accidents at work have detrimental effects on workers, company, and the general public. Despite the availability of H&S incident data, utilizing them to mitigate accident occurrence effectively is challenging due to inherent limitations of existing data logging methods. In this study, we used a text-mining approach for retrieving meaningful terms from data and develop six deep learning (DL) models for H&S risks management in power infrastructure. The DL models include DNN_classify (risk or no risk), DNN_reg1 (loss time), DNN_reg2 (body injury), DNN_reg3 (plant and fleet), DNN_reg4 (equipment), and DNN_reg5 (environment). An H&S risk database obtained from a leading UK power infrastructure construction company was used in developing the models using the H2O framework of the R language. Performances of DL models were assessed and benchmarked with existing models using test data and appropriate performance metrics. The overall accuracy of the classification model was 0.93. The average R² value for the five regression models was 0.92, with mean absolute error between 0.91 and 0.94. The presented results, in addition to the developed user-interface module, will help practitioners obtain a better understanding of H&S challenges, minimize project costs (such as third-party insurance and equipment repairs), and offer effective strategies to mitigate H&S risk.     

Biodiversity of the urban homegardens of São Luís city,Northeastern Brazil

There is a widely held notion that the increasing trend of urbanization accelerates loss of biodiversity and displaces native species. This study assessed the validity of this notion in the city of São Luís the capital of the state of Maranhão in the northeastern Brazil. The specific objectives of the study were to (1) assess plant and animal diversity of urban homegardens, (2) compare the diversity of homegardens in terms of origin of these species (exotic or indigenous to Brazil). We conducted a biodiversity survey in 40 randomly selected ‘quintais’ (hereafter called homegardens) from ten locations in the city of São Luis. We evaluated the species richness and diversity of various use categories of plant and animal species indigenous to Brazil as well as exotic species. A total of 186 species of plants in 68 families were recorded in the sampled homegradens. A total of 63 fruit tree species representing 34% of all tree species were found. Of these species, those indigenous to Brazil accounted for 58% of the cases, and this was significantly higher than the exotic species. Most of the species (60%) were indigenous to Brazil (wild and semi-wild domesticates), while the rest (40%) were exotic. A total of 42 species of vertebrates (mainly reptiles, birds and mammals) were also found in the homegardens, of which 47% were indigenous to Brazil. Some of the plant and animal species found in the homegardens are endangered species in their native habitats, suggesting that homegardens could provide a unique opportunity for their conservation and sustainable use. These species continue to play a vital role in the socioeconomic and ecological landscape of the city.     

Poverty‐aware social work practice: service users' perspectives

In recent years, there has been an increase in scholarly writing on the theory and practice of critical social work with people living in poverty. Yet there is a lack of research on the experiences and perspectives of service users regarding this kind of practice. This paper presents a qualitative study that explored the practice of a special poverty‐aware social work programme in Israel, through the experiences of women who took part in it. Using an interpretative interactionist approach, in‐depth interviews with nine women were held three times over a 2‐year period. Findings reveal a high degree of satisfaction with the programme on the part of the women. The satisfaction was derived from four main experiences: the experience of visibility, the experience of the active partnership in the fight against poverty, the experience of close, hierarchy‐challenging relationships, and the experience of responsiveness to material and emotional needs. The findings are discussed in terms of three principles of practice: intervention in a real‐life context, relationship‐based intervention and the focus on both the material and emotional needs and their fulfilment.     

Women's participation in self-help community development projects in Ndokwa agricultural zone of Delta State, Nigeria

The study was designed to assess women's participation in self-helpcommunity development projects in the Ndokwa agricultural zoneof Delta State, Nigeria. A total of thirty communities wereinvolved in the study. From the thirty communities, sixty-oneproject leaders were purposively selected. A total of thirtypurposively selected non-participant women were also interviewed.Semi-structured interview schedules were developed and usedin gathering information. Data were described through the useof frequency and percentage. The findings indicated that thewomen actually embarked on many self-help development projectsand the most common (19.6%) one was the cooperative society.A greater proportion (93.5%) of the identified projects hadbeen completed and they were functioning.     

Nigerian women seeking asylum in England on grounds of sexual violence

This study aims to give voice to the experiences of Nigerian women seeking asylum in the UK on the grounds of sexual violence. It draws upon in-depth narrative interviews with 10 Nigerian women, aged between 27 and 46, seeking asylum on the grounds of sexual violence. Women's accounts were analysed thematically, and the contextual factors that influenced the outcome of their asylum claims were explored. Findings show that women's asylum applications were affected by factors relating to lack of evidence, use of words and/or phrases that do not align with the English language meaning of sexual violence, Home Office's lack of understanding of cultural issues specific to women and peculiarity of women's narrative construction and the decommissioning of legal assistance. Findings also suggest that asylum organisations play a key role in providing holistic support to women. Recommendations are made for the Home Office's policies following these findings.
