A new alternative to the standard F test for clustered data

The data collection process and the inherent population structure are the main causes for clustered data. The observations in a given cluster are correlated, and the magnitude of such correlation is often measured by the intra-cluster correlation coefficient. The intra-cluster correlation can lead to an inflated size of the standard F test in a linear model. In this paper, we propose a solution to this problem. Unlike previous adjustments, our method does not require estimation of the intra-class correlation, which is problematic especially when the number of clusters is small. Our simulation results show that the new method outperforms the existing methods.     

Subjective Quality of Life in Zhuhai City,South China: A Public Survey Using the International Wellbeing Index

The study of subjective quality of life and its connotations in the People’s Republic of China is at a preliminary stage. Although there is an emerging body of literature on this topic, there are few datasets representative of the general public, particularly in Mainland China. This paper reports the findings of a public survey (N = 449) conducted in Zhuhai City, South China using the International Wellbeing Index (IWI). There were four main aims: (1) to judge whether residents were satisfied with their lives; (2) to compare the data with recent findings from Hong Kong and Macau; (3) to investigate the equivalence of the IWI in terms of its psychometric properties; and (4) to determine the applicability of the ‘Theory of Homeostasis Wellbeing’. The data indicated a moderate level of personal (PWI score = 64.4.) and national (NWI score = 57.4) wellbeing, consistent with recent findings from Hong Kong and Macau. The PWI score was within the normative range for non-Western countries, which indicates that the residents were, on the whole, satisfied with their lives. Although previously reported objective measures of quality of life in Zhuhai are lower than in Hong Kong and Macau, this is not reflected in this study’s subjective measures. This finding was interpreted in terms of the ‘Theory of Subjective Wellbeing Homeostasis’, and the specific situation in Zhuhai, as there seems to be an absence of factors (i.e., no harsh economic or social situation) which could drive subjective wellbeing below normal. Last, that the IWI demonstrated good psychometric performance in terms of its reliability, validity, and sensitivity, and concurred with previous published reports, it seems that the scale’s robustness generalises to Chinese samples.

Can the minimum living standard guarantee scheme enable the poor to escape the poverty trap in rural China?

The rural Minimum Living Standard Guarantee (Dibao) Scheme is the most important social assistance programme in rural China. However, how the rural Dibao programme affects household expenditures and whether it can enable the poor to escape the poverty trap are questions that remain largely unexplored. This study used data from the 2012 Rural Household Survey in China to investigate the impact of the rural Dibao programme on household expenditures. We found that the programme significantly improved the well‐being of low‐income households. Particularly, the programme significantly increased household expenditures on housing, education and health; furthermore, the impact was greater for households with educated household heads. However, the programme did not significantly affect household expenditures on food, transportation or farming inputs. The results imply that participation in the rural Dibao programme induces household investment in human capital, which could help to break the inter‐generational transmission of poverty and raise long‐run welfare.     

The Global Politics of Forced Labour

This article examines the politics of governing forced labour. It develops and applies an approach drawing on Marx’s conception of the historical formation of ‘free’ labour in the process of ‘primitive accumulation’ and Gramsci’s conception of the ‘relations of force’. Viewed through this lens, rather than representing discrete ontological categories, the boundary between ‘free’ and ‘forced’ labour is repositioned as largely a contested and ambivalent artefact of governance. The concept of the ‘political relations of force’ highlights the ways in which such constructions are shaped by complex intersections between a diversity of different social forces. This approach is subsequently applied in an analysis of an International Labour Organization project on dealing with ‘traditional slavery’ in Niger.     

A new generalized two-sided class of distributions with an emphasis on two-sided generalized normal distribution

The ordinary-G class of distributions is defined to have the cumulative distribution function (cdf) as the value of the cdf of the ordinary distribution F whose range is the unit interval at G, that is, F(G), and it generalizes the ordinary distribution. In this work, we consider the standard two-sided power distribution to define other classes like the beta-G and the Kumaraswamy-G classes. We extend the idea of two-sidedness to other ordinary distributions like normal. After studying the basic properties of the new class in general setting, we consider the two-sided generalized normal distribution with maximum likelihood estimation procedure.     

Asymmetric learning in a short-term,macro-oriented international students’ exchange: an exploratory study

International social work organizations’ call for a Global Agenda for Social Work and Social Development emphasizes promotion of social justice-oriented policies. A major challenge for international student exchange programs, especially when the visitors are from affluent countries, is to overcome the asymmetric process of the relative lack of power, in student hosts’ in comparison to student visitors’ relationships, as well as to focus on macro-practice orientation. Through analyzing a case study of student exchange, we propose a set of pedagogical strategies that may help to overcome these challenges through using processes of mirroring to address this asymmetric situation. This exploratory research is based on a three-year assessment of a short-term, macro-oriented MSW travel study course between graduate students from two universities (in the US and in Israel) using an exchange framework. It includes a comparison of joint experiences of students using both written and arts-based data. The findings demonstrate that the use of relationship building and mirroring enables both hosts and guests to learn about their own macro-reality through the eyes of the others and helps diffuse asymmetry and create relationships not only on the micro-, but also macro-levels. Implications for teaching methods in international courses are discussed.     

The relationship between the community participation of disabled youth and socioeconomic factors: mixed-methods approach in rural Sri Lanka

Mixed methods were applied to examine the association of community participation by disabled youth with socioeconomic factors in rural Sri Lanka. There was a significant association between community participation and socioeconomic factors in the quantitative survey (n = 116): participants living in socioeconomically disadvantaged conditions had lower levels of community participation than those living without these disadvantages. Consistent with the findings of the survey, previous educational experiences, household economic conditions, and perceived resource information were common themes in the qualitative study (n = 26). The dynamics of these factors, including marginalisation of disabled youth within the household, were also observed.
