Child well-being is described as a social problem, such that in most cases social indicators defined by experts are used, without much input from local and heterogeneous communities. This article makes the case for an innovative way to monitor and explore child well-being globally, while also critiquing currently used indices. Based on Nussbaum’s Capabilities approach, we propose to formulate indices by using GIS and a comprehensive list of relevant geospatial datasets, using uniquely designed meta-layers and feature catalogues. Moreover, we argue that these geospatial data can be collected and mapped by the local communities, through participatory approaches, thus not relying on authoritative engagement and data. This will contribute to the empowerment of communities, making them relevant stakeholders with valued contribution to the process. This paper outlines preliminary work related to concepts and ideas, whereas future work is planned to develop an elaborate and comprehensive GIS model, and conduct further spatial analysis in the framework of a small scale campaign.  相似文献

The present study investigated the relationship between Hong Kong people’s stereotype toward Mainland people and their own national attachment (i.e., national identity, constructive patriotism, and uncritical patriotism). The role of inter-group relationship as mediator and age as moderator of that relationship were also tested. A total of 1753 local Hong Kong people aged 17–80 (mean age = 20.35 years, SD = 5.02) completed anonymous questionnaires regarding their stereotypes toward Mainland people, inter-group relationship with Mainland people, and national attachment. As expected, stereotypes toward Mainland people, inter-group relationship and national attachment showed significant positive associations with each other. More interestingly, it was found that the inter-group relationship mediated the relationship between stereotypes toward Mainland people and three domains of national attachment, with this indirect link being weaker for younger Hong Kong adults than for older Hong Kong adults. Implications of the present findings for future research are discussed, as well as potential interventions for increasing subjective national attachment to China, especially in young Hong Kong people.  相似文献

Infant mortality in the Association of Southeast Asian Nations (ASEAN) has been declining, yet disparities remain between the nations. This paper therefore explores the determinants of infant mortality in the older ASEAN-4 economies, Malaysia, Thailand, Indonesia and the Philippines using an Autoregressive Distributed Lag (ARDL) Error Correction Model framework. The key findings of the study are: First, there is evidence of long-run relationships among infant mortality, education, female fertility, income and access to healthcare. Second, the determinants of infant mortality vary between countries. Female fertility emerged as the main determinant of infant mortality in Malaysia, while access to healthcare matter for infant mortality in Indonesia, and to a lesser extent for the Philippines. The income effect is significant for reducing infant mortality in Malaysia, while female education is important for Indonesia and Thailand. Third, the speed of adjustment of infant mortality rate is comparatively low in ASEAN-4.  相似文献

Land and Michael’s (this issue) offer an excellent overview of the evolving status of the social indicators movement, with thoughtful recommendations for future research. I argue that QOL researchers may want to consider paying increased attention to advances in the science of personality development, such as those articulated in McAdams' (The art and science of personality development. Guilford Press, New York, 2015), in conceptualizing comprehensive assessments of the QOL. Specifically, McAdams' synthesis of the literature on personal agency should provide a useful beginning for developmentally-informed discussions of the potential evolving nature of QOL and its antecedents, correlates, and consequences, with the goal of ensuring greater relevance of QOL evaluations to all age groups.  相似文献

This paper describes the methodology and main results from an overall assessment on future achievement of sustainable development goals. The proposed approach consists of a model-based, looking forward composite sustainable development index—FEEM sustainability index—projected to the future. It represents a first experiment to reproduce the future dynamics of sustainable development indicators over time and worldwide and to assess future sustainability under different scenarios. The assessment presented here is relevant under different viewpoints. First, it has a very broad nature in terms of both geographical coverage and meaningfulness: it considers the multi-dimensional structure of sustainable development by combining relevant indicators belonging to economic, social and environmental pillars for the whole world. Second, the modelling framework to compute future trends of indicators relies upon a recursive-dynamic computable general equilibrium model. This is an ideal tool to look simultaneously at the development of many indicators, their potential interactions and trade-offs, and more in general to the consequences of economic development and/or policies aiming to increase performance in one or more indicators; it allows measuring the overall sustainability under alternative scenarios, across countries and over time. Finally, regarding the construction of the composite indicator, the application of fuzzy measures and Choquet integral increases substantially the model capability allowing taking into account the interactions that exist among the three main pillars of sustainability and the considered indicators.  相似文献

This paper analyzes the data from the Population Census of 2011 to identify the characteristics of poor ethnic minority groups in Hong Kong and the factors that are associated with child poverty among these ethnic minorities. The results show that the child poverty level varies between different ethnic groups and that ethnic minorities from developing nations are likely to have a higher poverty level. In particular, Pakistani children have the highest poverty rate among all ethnic groups. The results also show that Pakistani, Nepalese, and Mixed (Chinese and Asian) nationalities have a higher child poverty rate than that of Chinese individuals who constitute the majority of the Hong Kong population. The main reason for this is that, unlike their Chinese counterparts, some of these ethnic minority households have not benefited from their own human capital or their length of exposure in the local society in Hong Kong. And even if they have benefited, the positive impact of these factors on ethnic minority households was much weaker compared to that of Chinese households. These results suggest that ethnic minorities need to be categorized as a separate group in order to assess their specific needs, and assimilation policies, especially support on Chinese language learning, need to be an integral part of the government’s poverty reduction strategy to reduce child poverty among ethnic minorities.  相似文献

Problem

Pacific Islanders are disproportionately burdened by poorer maternal health outcomes with higher rates of pre-term births, low birth weight babies, infant mortality, and inadequate or no prenatal care.

Purpose

The purpose of this study was twofold: (1) to explore maternal health care providers’ perceptions and experiences of barriers in providing care to Marshallese women, and (2) providers perceived barriers of access to care among Marshallese women. This is the first paper to explore perceived barriers to maternal health care among a Marshallese community from maternal health care providers’ perspectives in the United States.

Methods

A phenomenological, qualitative design, using a focus group and in-depth interviews with 20 maternal health care providers residing in northwest Arkansas was chosen.

Findings

Several perceived barriers were noted, including transportation, lack of health insurance, communication and language, and socio-cultural barriers that described an incongruence between traditional and Western medical models of care. There was an overall discord between the collectivist cultural identity of Marshallese families and the individualistic maternal health care system that merits further research.

Discussion

Solutions to these barriers, such as increased cultural competency training for maternal health care providers and the incorporation of community health workers are discussed.  相似文献

Although subprime mortgage lending and unemployment were largely responsible for the wave of foreclosures during the Great Recession, additional sources of financial risk may have exacerbated the crisis. We hypothesize that many parents sending children to college were financially overextended and vulnerable to foreclosure as the economy contracted. With commuting zone panel data from 2006 to 2011, we show that increasing rates of college attendance across the income distribution in one year predict a foreclosure rate increase in subsequent years, net of fixed characteristics and changes in employment, refinance debt, house prices, and 19-year-old population size. We find similar evidence of college-related foreclosure risk using longitudinal household data from the Panel Study of Income Dynamics. Our findings uncover a previously overlooked dimension of the foreclosure crisis, and highlight mortgage insecurity as an inadvertent consequence of parental investment in higher education.  相似文献

This study illuminates the association between cigarette smoking and adult mortality in the contemporary United States. Recent studies have estimated smoking-attributable mortality using indirect approaches or with sample data that are not nationally representative and that lack key confounders. We use the 1990–2011 National Health Interview Survey Linked Mortality Files to estimate relative risks of all-cause and cause-specific mortality for current and former smokers compared with never smokers. We examine causes of death established as attributable to smoking as well as additional causes that appear to be linked to smoking but have not yet been declared by the U.S. Surgeon General to be caused by smoking. Mortality risk is substantially elevated among smokers for established causes and moderately elevated for additional causes. We also decompose the mortality disadvantage among smokers by cause of death and estimate the number of smoking-attributable deaths for the U.S. adult population ages 35+, net of sociodemographic and behavioral confounders. The elevated risks translate to 481,887 excess deaths per year among current and former smokers compared with never smokers, 14 % to 15 % of which are due to the additional causes. The additional causes of death contribute to the health burden of smoking and should be considered in future studies of smoking-attributable mortality. This study demonstrates that smoking-attributable mortality must remain a top population health priority in the United States and makes several contributions to further underscore the human costs of this tragedy that has ravaged American society for more than a century.  相似文献
