This paper presents the findings from an innovative project funded by the International Association of Schools of Social Work (IASSW) and undertaken by an international team of academics investigating the development of a global curriculum for social work in the context of political conflict. Coupled alongside the emerging research and literature on the subject, our small-scale survey findings indicate support for the need for social work educators to address political conflict more systematically within social work curricula at both undergraduate and post-qualifying levels of social work education. This paper illuminates the opportunities for creative pedagogy whilst also examining the threats and challenges permeating the realisation of such initiatives. In this way, the implementation of a proposed curriculum for political conflict is given meaning within the context of IASSW's Global Standards for social work education. Given the exploratory nature of this project, the authors do conclude that further research is warranted in regard to potential curriculum development and suggest using a comparative case study approach with more in-depth qualitative methods as a way to address this.  相似文献

Food systems are of increasing interest in both research and policy communities. Surveys of post-socialist countries of Central and Eastern Europe (CEE) show high rates of food self-provisioning. These practices have been explained in terms of being ‘coping strategies of the poor’. Alber and Kohler’s ‘Informal Food Production in the Enlarged European Union’ (2008) offers a prominent account of this argument, supported by quantitative data. However, evidence from our case study of food self-provisioning in one CEE state–Czechia–contradicts their findings. Newly commissioned survey data, as well as a fresh look at the data they were working from, demonstrate that rather than being motivated by poverty, these widespread practices serve as a hobby and as a way of accessing ‘healthy food’. With food self-provisioning becoming an increasingly prominent subject in advanced industrial countries, in terms of both health and environmental policy, we propose that much greater care is taken in researching and interpreting the reasons for differences in food systems. Our findings are that environmentally sustainable and healthy self-provisioning in Czechia is motivated by a range of reasons, and practised by a significant proportion of the population across all social groups. This conclusion questions linear narratives of progress that figure ‘western’ practices as advanced or complete or automatically desirable, and contributes in a modest way to a decentring of narratives of progress.  相似文献

The purpose of this paper is to find out whether serum oxidizability potential measured before an exercise test (EXT) correlates with age and ischemic heart disease severity. Oxidizability potential was determined in 3 age groups, in gr. I patients < 45 years, in gr. II age range = 45 - 70years {\hbox{range}} = {45} - {7}0{\hbox{years}} , and in gr. III patients > 70 years. Included subjects had chronic ischemic heart disease (IHD) and underwent a symptom-limited EXT upon initiation of a cardiac rehabilitation program. The thermo-chemiluminescence (TCL) assay was used to assess serum oxidizability potential. This assay is based on heat-induced oxidation of serum, leading to the formation of electronically excited species in the form of unstable carbonyls, which further decompose into stable carbonyls and light energy (low chemiluminescence). Measured photons emission is represented by a kinetic curve which is described by its amplitude and slope (=ratio). We assessed the correlations of TCL ratio with age, exercise duration, metabolic equivalents (METS), maximal heart rate (mHR), maximal systolic BP, >1 mm S-T depression, diabetes, hypertension, smoking, left ventricular ejection fraction (LVEF)> or <40%, previous myocardial infarction, and aorto-coronary bypass surgery. A high TCL ratio (%) correlated well with METS (r = 0.82), mHR (r = 0.77) and with exercise-induced S-T segment shift (r = 0.86, p < 0.05). A lower serum oxidizability potential, expressed as a low TCL ratio, thus suggestive of a previous high oxidative stress, was found in the two older age groups compared to gr. I (<45 years), p = 0.041, and in particular, in gr. III patients with low LVEF%. The TCL ratio (%) in gr. III was 188.7 ± 14.5, 192 ± 17 in gr. II, and 214 ± 13 in gr. I (p < 0.05), and was 166 ± 13.1 in gr. III with LVEF < 45% as compared to 271 ± 15.7 in gr. I patients with LVEF > 45% (p < 0.01). A trend for lower TCL ratio (%) was found in diabetic, hypertensive, and post-coronary bypass surgery patients. A paradoxically low TCL ratio (low oxidizability potential) was observed in patients without S-T depression compared to patients with S-T depression (189 ± 22 vs. 201 ± 15, p = NS), due to the fact these patients had a much lower LVEF% and a lower exercise capacity. Serum oxidizability potential is associated with age, EXT parameters, results, and IHD severity. TCL ratio is an “easy-to-measure marker” that might be incorporated into risk assessment and prediction in aged IHD patients.  相似文献

Fitting a linear regression for a response variable by minimising the sum of absolute deviations, L1 regression, may be viewed as a maximum likelihood procedure applied to the Laplace distribution. An interesting bivariate case is where the conditional distribution of the response X2 given X1 and the marginal distribution of the explanatory variable X1 are both Laplace. In this context we show there is information to distinguish the direction of dependence between X1 and X2 from observations. That is we may distinguish the model in which X1 is dependent on X2 from that in which X2 is dependent on X1 This is not true for L2 regression based on the Normal distribution.  相似文献

Social Science is increasingly called on to address “grand challenges”, “wicked problems”, “societal dilemmas” and similar problematiques. Examples include climate change, the war on drugs and urban poverty. It is now widely agreed that the disciplinary structure of academic science, with its journals, curricula, peer communities, etc., is not well suited to such trans-disciplinary, ill-bounded, controversial issues, but the ways forward are not yet clear or accepted by the mainstream. The concept of a next generation paradigm of “Science 3.0” has emerged through work on sustainability systems analysis, and for this multiple channels for learning, thinking and communications are essential. Visual thinking in its many forms (from technical representation or mapping, to photography or video, to design or illustration, to fine art) can bring to the table tacit and “felt” knowledge, creative experience and links from analysis with synthesis. This paper first sketches the contours of a Social Science 3.0, and then demonstrates with examples how visual thinking can combine with rational argument, or extend beyond it to other forms of experience.  相似文献

Though religion has been related to better mental health, the aspects of organized religious life most salient for the mental health of Caribbean Black adolescents in the US, beyond religious service attendance, has been understudied. This research utilized a sub-sample of Caribbean Black adolescents from the NSAL-A, a nationally representative U.S. dataset, to examine (1) the prevalence of organized religious involvement (e.g., participation in religious service activities, choice to attend religious services) and (2) the relationship between organized religious involvement and mental health. Results showed that 62 % of Caribbean Black adolescents attend religious services regularly (at least a few times a month) and 49 % or more attend religious services or participate in religious activities (e.g., youth groups) by choice. Additionally, various aspects of organized religious involvement were positively related to coping and self-esteem, and negatively related to depressive symptoms. Religious service attendance was not related to any of the mental health indicators. Study results can inform the development of individual and group level interventions targeted at supporting the mental health of Caribbean Black adolescents.  相似文献

The idea of community-based organisations (CBOs) owning or managing physical assets, such as land or buildings, has a long history in many countries. This paper examines policy and practice in the UK where there has been significant interest in this field. A variety of benefits have been attributed to the role of assets including motivating community engagement, providing a vehicle for outsourcing public services, or creating financially sustainable organisations. The empirical research reveals there is a heterogeneous set of CBOs holding assets, but the majority of them are small with few paid staff. The analysis proposes a spectrum of CBO types in the field. It concludes that policy makers will need to recognise that these types are informed by contrasting traditions, ideas and operating logics that affect their different practices and resource dependencies.  相似文献

Child protection services in Australia and elsewhere face increasing internal and external demands. As a response to these pressures, in part at least, services are increasingly implementing some form of risk assessment procedures. This article examines the practice implications of the increasing use of risk assessment instruments in child protection services. It highlights the complexity of the concept of risk as the basis for a future‐oriented assessment activity. The authors suggest that this change of time frame (from what has happened to what might happen) may be detrimental to children. Through a critical review of the literature, the authors question whether risk prediction is possible and discuss the limitations of risk assessment instruments which omit some risk factors and may ignore the perspective of the child. The authors challenge the validity of risk assessment instruments in statutory settings and suggest that the protection of the organization may be a major objective in their implementation.
