Transnational Corporations and Global Governance

Scholars and critics often lament that corporations rule the world, but predominant accounts of global governance imply almost the opposite: With theories populated by national governments and intergovernmental and nongovernmental organizations, it might appear that nearly everyone except corporations writes the rules that govern across borders. This article compiles research on the varied ways in which multinational and transnational corporations have shaped global governance, drawing attention to the contours and limits of corporate power. Corporations can be seen variously as sponsors, inhibitors, and direct providers of global governance. They have, for example, been sponsors of neoliberal trade rules, inhibitors of some labor and environmental regimes, and providers of private standards for finance, safety, sustainability, and human rights. Scholars may be tempted to focus on just one of these roles or to presume unified corporate dominance, but it is important to grapple with all three and to investigate the conditions under which corporate actions are more or less unified and decisive.Introduction National, multinational, and transnational corporations in sociology Sponsors Inhibitors Providers: The rise of private authority Implications Disclosure statement Acknowledgements Literature cite

The role of human capability and resilience

In this article some of the findings emerging from a research network investigating the socio-economic, biological and psychological circumstances that contribute to human capability and resilience over the life course [www.ucl.ac.uk/capabilityandresilience] are reported. The network, funded by the Economic and Social Research Council (ESRC), brought together scientists from diverse disciplines including experts from psychology, psychiatry, sociology, economics, epidemiology, geography, and social policy. The diverse backgrounds of the team reflect the complexity of the topic, which has to be tackled from different angles in order to generate a better understanding of the factors and processes that make it possible for individuals to lead healthy and rewarding lives

Use of night-time positioning equipment in care home residents with postural asymmetry : a pilot study

Twenty four-hour postural care that includes the use of night-time positioning equipment (NTPE) is being increasingly recommended. However, because most of the published studies focus on children, there is a lack of evidence on the use of NTPE in adults. The aim of this pilot study was to assess the effect of NTPE use in UK care home residents with complex health conditions and postural asymmetry. Ten care home residents trialled NTPE over a 12-week period. Qualitative and quantitative data were collected before and after each trial using standardised assessment tools. Semi-structured interviews were conducted with participants and relatives after each trial. Staff's views were elicited via two focus groups at the end of the study. There were notable benefits of NTPE use in terms of participants' pain levels, sleep quality, risk of pressure ulcers, risk of choking, and weight. There was also evidence of improvements in participants' function, ability to undertake activities of daily living and quality of life. However, some equipment was abandoned during the trials because participants found it too hot or restrictive. This pilot study increases the evidence base for a personalised approach to 24-hour postural care that can support older people's health and well-being. Further empirical studies are required to determine how NTPE can be used to improve older people's quality of life. [Abstract copyright: © 2020 RCN Publishing Company Ltd. All rights reserved.

Women?s health in mid-life: life course social roles and agencyas quality

Data from a prospective British birth cohort study showed that women who were childless, lone mothers or full-timehomemakers between the ages of 26 and 54 were more likely to report poor health at age 54 than women who occupiedmultiple roles between these ages. To explain this finding we developed and tested a theory of role quality based on theconcept of agency by drawing on Giddens? theory of structuration and Doyal and Gough?s theory of human needs.According to our theory, the patriarchal structuration (drawing on Giddens? term) of work and family roles provides bothlimitation and opportunity for the expression of agency. Doyal and Gough?s theory of human needs was then used toidentify the restriction of agency as a possible influence on health. This theory of role quality was operationalised using ameasure of work (paid and unpaid) quality at age 36 and a measure of work and family stress between ages 48 and 54. Therelatively poor subjective health in mid-life of lone mothers was explained by work and family stress and adult social class.In contrast, the poor health in mid-life of long-term homemakers and childless women was less easily explained.Homemaker?s excess risk of reporting poor health at age 54 remained strong and significant even after adjusting for rolequality and socioeconomic indicators, and childless women were at an increased risk of reporting poor health despite thesocial advantage inherent in attaining educational qualifications and occupying professional or managerial occupations.This study highlights the need to develop measures of role quality specifically designed to capture agency aspects of socialroles

Contrastive Hebbian Learning with Random Feedback Weights

Neural networks are commonly trained to make predictions through learning algorithms. Contrastive Hebbian learning, which is a powerful rule inspired by gradient backpropagation, is based on Hebb's rule and the contrastive divergence algorithm. It operates in two phases, the forward (or free) phase, where the data are fed to the network, and a backward (or clamped) phase, where the target signals are clamped to the output layer of the network and the feedback signals are transformed through the transpose synaptic weight matrices. This implies symmetries at the synaptic level, for which there is no evidence in the brain. In this work, we propose a new variant of the algorithm, called random contrastive Hebbian learning, which does not rely on any synaptic weights symmetries. Instead, it uses random matrices to transform the feedback signals during the clamped phase, and the neural dynamics are described by first order non-linear differential equations. The algorithm is experimentally verified by solving a Boolean logic task, classification tasks (handwritten digits and letters), and an autoencoding task. This article also shows how the parameters affect learning, especially the random matrices. We use the pseudospectra analysis to investigate further how random matrices impact the learning process. Finally, we discuss the biological plausibility of the proposed algorithm, and how it can give rise to better computational models for learning

Future career plans of Malawian medical students: a cross-sectional survey.

BACKGROUND: Malawi has one of the lowest physician densities in the world, at 1.1 doctors per 100,000 population. Undergraduate training of doctors at the national medical school has increased considerably in recent years with donor support. However, qualified doctors continue to leave the public sector in order to work or train abroad. We explored the postgraduate plans of current medical students, and the extent to which this is influenced by their background. METHODS: A self-administered questionnaire was developed after discussion with students and senior staff. This included questions on background characteristics, education before medical school, and future career plans. This was distributed to all medical and premedical students on campus over 1 week and collected by an independent researcher. One reminder visit was made to each class. Chi-squared tests were performed to investigate the relationship of student characteristics with future career plans. RESULTS: One hundred and forty-nine students completed the questionnaire out of a student body of 312, a response rate of 48%. When questioned on their plans for after graduation, 49.0% of students plan to stay in Malawi. However, 38.9% plan to leave Malawi immediately. Medical students who completed a 'premedical' foundation year at the medical school were significantly more likely to have immediate plans to stay in Malawi compared to those who completed A-levels, an advanced school-leaving qualification (P = 0.037). Current premedical students were slightly more likely to have immediate plans to work or train in Malawi compared to medical students (P = 0.049). However, a trend test across all the years was not significant. When asked about future plans, nearly half of students intend to work or train outside Malawi. CONCLUSIONS: The majority of respondents plan to leave Malawi in the future. The effectiveness of the substantial upscaling of medical education in Malawi may be diminished unless more medical students plan to work in Malawi after graduation
