Modelling childhood malnutrition in Zambia: an adaptive Bayesian splines approach

Nutritional status of a child is an important determinant factor of his/her health and survival. Evaluation of child nutritional status is usually based on three anthropometric indices of height-for-age (stunting), weight-for-height (wasting) and weight-for-age (underweight). This paper is a case study that focuses on a new approach of estimating nonlinear effects. It models the dependence of probability of underweight children in Zambia on some covariates, some of which are metrical whose effects are assumed to be nonlinear and estimated nonparametrically through a Bayesian B-spline basis function approach with adaptive knot selection using the data set from the 1992 Zambia Demographic and Health Survey (ZDHS). For all the unknown functions, the number and location of knots as well as the unknown coefficients of the basis functions are estimated simultaneously using reversible jump Markov chain Monte Carlo (RJMCMC) techniques.     

Identity work of welfare service users in participatory spaces

The popularizing user participation agenda has encouraged the creation of discursive spaces for collaborative decision‐making with the welfare service users. Despite the claim of partnership with the service users, these participative spaces do not always promise parity of participation. Based on a qualitative study conducted in Hong Kong, this paper discusses the manifestation and constitution of identity among the welfare service users who took part in organizational spaces for participatory management. The analysis uncovers the tensions and promises in participatory management with the welfare service users.     

Job stress and productivity increase

This paper examines mental and physical pressures that workers bear at work. The authors discuss how on the-job stress affects a person's capabilities and productivity, and how such pressures lend to higher incidences of accidents at work. The paper also discuss methods of reducing job-related stress and increasing productivity. An intervention was conducted amongst workers in a private firm. It shows mental and emotional pressure can affect performance and productivity of a worker on the job. One of the biggest influences of today's worker is on the-job stress. Job stress occurs when the requirements of the job do not match the capabilities, resources, or needs of the worker. This consequently affects how a person would normally deal with customer service problems, grievances, violence, conflict, and decisions on the job. Stress is an inevitable part of everyday life, and is therefore a distinct part of a person's job. To properly control the outcome of stress, there are certain precautions and methods that should be taken that will boost productivity.     

Affect and leader-member exchange in the new millennium: A state-of-art review and guiding framework

The idea that affect plays a key role in leader-member exchange (LMX) processes is not new, but it has become a subject of considerable research attention since the turn of the Millennium. This interest has, however, resulted in a multiplicity of views that have tended to obfuscate rather than clarify the affect-LMX nexus. To deal with this lack of clarity, we conducted a systematic integration of affect-LMX literature published in leading journals since 2000, including the role of personal affectivity, discrete affect, emotional intelligence, emotional labor, and affective climate. We structured our review using a multilevel framework of affect that encompasses five levels of analysis: (1) within-person, (2) between persons, (3) interpersonal, (4) team, and (5) organizational levels; as well as consideration of cross-level effects. We address in particular three fundamental issues that we argue may have hampered the development of the affect-LMX nexus in the literature: theoretical diversity, problems of data analysis, and measurement issues. We conclude by discussing opportunities for future research across the different levels and develop a set of research questions that we hope will help to promote research into the role of affect in LMX.     

Evaluating the effectiveness of four Hong Kong antismoking cartoon posters with humor and threat elements

Although cartoons are widely used in health communication, their effectiveness has seldom been tested. In this study, the effects of four humor–threat antismoking cartoon posters are evaluated in a sample of 12- to 15-year-olds (n = 183) in Hong Kong. The five-group comparison (including the control group) revealed that these posters did not increase antismoking attitudes in the sample but did decrease antismoking behavioral intentions. The better liked, more humorous, and more frightening posters did not produce increased antismoking attitudes or behavioral intentions. These findings warrant the development of theories to clarify the role of humor in health communication. Although cartoons are well liked by adolescents, practitioners must be aware of the possible negative effects of humor in cartoon-based messages.     

Administrative Buy-in for User Participation in Managing Social Services

Abstract

This paper reports the findings of a study conducted in Hong Kong on the value position of the social service providers regarding user participation in service management. Using a survey instrument to collect data from 642 service providers in an elderly service organization, the study explored whether or not the value position had an effect on the views of the service providers on the structural set-up for user participation, and whether the value position of the professional staff was significantly different from that of the non-professional staff. Exploratory factor analyses (EFA), confirmatory factor analyses (CFA) and structural equation modeling (SEM) were applied in the analysis. The findings identify that administrative buy-in needed to support shared decision-making with the welfare service users has not been achieved in the studied organization, owing to the absence of value commitment to the user participation cause. As the professional staff was more supportive of values favoring user participation, the paper calls for an acculturation process that would be stimulated and led by professionals to develop a participatory culture. The paper also recommends conducting similar study on a larger scale and qualitative inquiry into factors influencing the formation of values about user participation in future research.     

Contesting middle-class civility: place-based collective identity in Hong Kong’s Occupy Mongkok

The global wave of popular protests since 2011 has highlighted the importance of place to contentious politics. Focusing on Hong Kong’s Umbrella Movement, this article analyzes how place, when dramatized by the practice of protest camping, shapes collective identity formation and contestation. By examining the Mongkok protest camp, I argue that the symbolic meanings being attributed to the place have shaped a collective identity distinctive from other local protests. This place-based collective identity was constituted by two dimensions: a tactical dimension that advocated militant actions against the police and counter-protesters; and an associational dimension that sought to identify with the grassroots in political activism. While its formation helped to galvanize protesters’ solidarity at the early stage of the movement, the two dimensions gradually generated intensive conflicts, which eventually weakened solidarity and the movement claims.     

Integrating performance and risk aspects of supply chain design processes

Abstract

Supply chain design is a complex and relatively poorly structured process, involving choosing many decisional parameters and it usually requires consideration of numerous sources of uncertainty. Many conventional processes of supply chain design involve taking a deterministic approach, using point estimates, on important measures of supply chain effectiveness such as cost, quality, delivery reliability and service levels. Supply chain disruptions are often separately considered as risks, both in the research literature and in practice, meaning that a purely traditional risk management and risk minimization approach is taken. We have developed and applied an approach that combines the intellect and experience of the supply chain designer with the power of evaluation provided by a Monte Carlo simulation model, which uses decision analysis techniques to explicitly incorporate the full spectrum of uncertain quantities across the set of alternative supply chain designs being considered. After defining and setting out the general decision variables and uncertainty factors for 16 distinct supply chain design decision categories, we then apply that approach to combine the decision-makers’ heuristics with the probabilistic modeling approach, iteratively, to achieve the best of both elements of such an approach. This novel approach to fully integrating performance and risk elements of supply chain designs is then illustrated with a case study. Finally, we call for further developmental research and field work to refine this approach.

Racial/ethnic segregation and health disparities: Future directions and opportunities

Health researchers have investigated the association between racial segregation and racial health disparities with multilevel approaches. This study systematically reviews these multilevel studies and identifies broad trends and potential directions for future research on racial segregation and health disparities in the US. After searching databases including CINAHL and MEDLINE, we systematically reviewed 66 articles published between 2003 and 2019 and found four major gaps in racial/ethnic segregation and health disparities: (a) the concept of segregation was rarely operationalized at the neighborhood level, (b) except for the evenness and exposure dimension, other dimensions of segregation are overlooked, (c) little attention was paid to the segregation between whites and non‐black minorities, particularly Hispanics and Asians, and (d) mental health outcomes were largely absent. Future directions and opportunities include: First, other segregation dimensions should be explored. Second, the spatial scales for segregation measures should be clarified. Third, the theoretical frameworks for black and non‐black minorities should be tested. Fourth, mental health, substance use, and the use of mental health care should be examined. Fifth, the long‐term health effect of segregation has to be investigated, and finally, other competing explanations for why segregation matters at the neighborhood level should be answered.
