Asymptotic normality of frequency polygons for random fields

The purpose of this paper is to investigate asymptotic normality of the frequency polygon estimator of a stationary mixing random field indexed by multidimensional lattice points space Z^N$Z^N$. Appropriate choices of the bandwidths are found.     

The Value of Community Cohesion Among Vietnamese Students in Era of Urbanisation and Globalisation

The concept of community cohesion as applied in social research is about more than tackling social exclusion and also involves sustaining relationships of trust and neighbourly interaction. Community cohesion is a function of connections and relations maintained between individuals, groups and associations. It can be fostered through measures that build feelings of trust, safety and belonging between people and can form a basis for shared values and norms of behaviour. This concept originates from Emile Durkheim, who identified the interdependence between members of a social group who share solidarity, loyalties and responsibilities. In Vietnam, various idioms and proverbs about social solidarity and social cohesion express the significant role of community in the lives of individuals as well as an individual’s responsibilities towards the community. Recent public debates suggest that social cohesion is changing or fraying, especially among youth, owing to the social, economic and cultural impacts of globalisation and urbanisation. However, there is lack of research focusing on community cohesion among young people in general and students in particular in the Vietnamese context. This paper reports on a research project on student life conducted in twelve Hanoi universities, and with 484 research participants, utilizing surveys, interviews and focus groups. This paper aims to identify the current situation and trends in student values with regards to community, particularly their views on community participation, and their responsibilities to communities, friends and society in general. The findings suggest that in spite of significant changes associated with urban life and globalisation, students still positively value community cohesion and engage in practices that maintain solidarity, trust and interdependencies with a range of consociates.     

The Psychological and Health Consequences of Caring for a Spouse With Dementia: A Critical Comparison of Husbands and Wives

Caring for someone with dementia can be demanding, particularly for spouses living with the care recipient. The main goal of this study was to clarify differences in the experience of caregivers who were husbands and wives with respect to burden, health, healthy behaviors, presence of difficult care recipient behaviors, social supports, and the quality of the premorbid relationship. The results of this study support research demonstrating a difference between the caregiving experiences of women and men. It is becoming increasingly apparent that female gender is a marker that places them at increased risk of high burden and less support.     

Ethnic community supports and psychological well-being of Vietnamese refugees

This study examines the psychological well-being of 160 Vietnamese refugees in the US. Path analysis was performed by using version 6 of LISREL to assess the structural relationships between variables included in the analysis. The findings reveal that ethnic community supports, self-esteem, and income have significant direct effects on psychological well-being. In addition, education, length of residence, English speaking ability, and social adjustment have significant indirect effects on psychological well-being     

Second‐Generation Decline or Advantage? Latino Assimilation in the Aftermath of the Great Recession

This article addresses the debate on second‐generation advantage and decline among Latinos by providing a post‐recession snapshot based on geocoded data from the Current Population Survey (2008–2012). It reports three findings. First, second‐generation Mexicans and Puerto Ricans are at a disadvantage, whereas other Latinos have achieved parity with native majority peers. Second, second‐generation Latinos report significant progress compared to their parents and there is no evidence of a second‐generation decline. Third, there is no difference in outcomes among second‐generation Mexicans by immigrant destination type. Overall, these analyses yield an optimistic assessment of second‐generation progress, while noting potential stagnation among third‐ and higher‐generation Mexicans.     

Perspective: Risk Apportionment and Disease Intervention Strategies

The ultimate public health objective is the ability to predict and prevent disease, and not necessarily to identify an exhaustive list of potential disease risk factors. For any important public health outcome with multiple and potentially interrelated risk factors, an improved understanding of the contribution of individual and combinations of modifiable risk factors to the disease burden is essential for formulating an appropriate public health strategy. Partitioning techniques that divide the combined impact of multiple risk factors into exposure-specific components while taking into account the potential interrelations among those components, have been described in the epidemiological literature. In this article, we review and compare the available methods and options for such apportionment and apply them in a more general public health context as a method of selecting and prioritizing coronary heart disease (CHD) prevention strategies.     

Configurations of Autonomy and Relatedness in a Multiethnic U.S. Sample of Parent–Adolescent Dyads

Configurations of autonomy and relatedness were explored in 232 adolescent–parent dyads. Youth (58% female) were 13–18 years old and ethnically diverse (38% Latino American, 32% European American, 30% African American). Cluster analysis was used to identify three distinct groups based on youth and parent reports of parental autonomy support and family relatedness. The three clusters differed on key demographics (e.g., parent education and income, immigrant background, ethnicity) and theoretically relevant indicators of family and individual functioning (e.g., parent and youth reports of decision making and family obligations; youth‐reported attachment and minor delinquency). Findings provide empirical support for theoretical models of autonomy–relatedness (e.g., Journal of Cross‐Cultural Psychology, 36, 2005, 403) and contribute to understanding of how autonomy and relatedness intersect to influence adolescent and family adaptation.     

A Comparison of Egg Consumption with Other Modifiable Coronary Heart Disease Lifestyle Risk Factors: A Relative Risk Apportionment Study

Guidelines from the American Heart Association (AHA) recommend that healthy adults limit their intake of dietary cholesterol to less than 300 mg per day. Since a large egg contains about 71% of that amount, the AHA recommends restricting egg consumption unless dietary cholesterol intakes from other sources are limited. We applied a risk apportionment approach to estimate the contribution of egg consumption and other modifiable lifestyle risk factors (e.g., smoking, poor diet, minimal exercise, and alcohol intake) to coronary heart disease (CHD) risk at the population level. Specifically, we categorized the U.S. adult population ages 25+ into distinct risk groups based on the prevalence of modifiable lifestyle risk factors and applied an apportionment model, typically used to assess risk contribution at the individual level, to estimate the contribution of egg intake to CHD risk. Our analysis shows that the combination of modifiable lifestyle risk factors accounts for less than 40% of the population CHD mortality. For the majority of U.S. adults age 25+, consuming one egg a day accounts for <1% of CHD risk. Hence, focusing on decreasing egg intake as an approach to modify CHD risk would be expected to yield minimal results relative to changing other behaviors such as smoking and other dietary habits.
