Rurality and well-being during the middle years of life

Popular stereotypes and theorizing by social scientists suggest that rural people are more satisfied with their communities and happier with their life situations than are their nonrural counterparts. This enhanced well-being is believed to result at least partly from the presence of kinship and friendship ties in the local community and the adherence to traditional religious beliefs. Data from a panel study of nearly 1200 middle aged persons from Pennsylvania surveyed in 1971 and 1984 provided indices of community satisfaction and happiness. When income was controlled, country residents expressed slightly higher levels of community satisfaction than did town or urban dwellers in both time periods. Happiness was not related to residence location. Income was a relatively more important predictor of community satisfaction and happiness among urban than among country residents, while number of friends was relatively more important for rural residents. Number of kin living nearby and adherence to traditional religious beliefs were not related to well-being regardless of residence location.     

The min-p robust optimization approach for facility location problem under uncertainty

Improper value of the parameter p in robust constraints will result in no feasible solutions while applying stochastic p-robustness optimization approach (p-SRO) to solving facility location problems under uncertainty. Aiming at finding the lowest critical p-value of parameter p and corresponding robust optimal solution, we developed a novel robust optimization approach named as min-p robust optimization approach (min-pRO) for P-median problem (PMP) and fixed cost P-median problem (FPMP). Combined with the nearest allocation strategy, the vertex substitution heuristic algorithm is improved and the influencing factors of the lowest critical p-value are analyzed. The effectiveness and performance of the proposed approach are verified by numerical examples. The results show that the fluctuation range of data is positively correlated with the lowest critical p-value with given number of new facilities. However, the number of new facilities has a different impact on lowest critical p-value with the given fluctuation range of data. As the number of new facilities increases, the lowest critical p-value for PMP and FPMP increases and decreases, respectively.

     

A beta-inflated mean regression model with mixed effects for fractional response variables

Abstract

In this article we propose a new mixed-effects regression model for fractional bounded response variables. Our model allows us to incorporate covariates directly to the expected value, so we can quantify exactly the influence of these covariates in the mean of the variable of interest rather than to the conditional mean. Estimation is carried out from a Bayesian perspective. Due to the complexity of the augmented posterior distribution, we use a Hamiltonian Monte Carlo algorithm, the No-U-Turn sampler, implemented using the Stan software. A simulation study was performed showing that our model has a better performance than other traditional longitudinal models for bounded variables. Finally, we applied our beta-inflated mean mixed-effects regression model to real data which consists of utilization of credit lines in the peruvian financial system.     

宋代理学话语的形成

陈来认为,宋明理学之所以成为理学,全在于它形成了一套相对稳定的话语体系。深入细致地研究这一话语体系的形成过程,有利于总结和提炼中国学术思想话语体系的构型特性。杨国荣认为,对心性和体性的关注,构成了理学的重要特点。心性之学分别从人自身的存在和人与对象关系的维度展开了对意义的追寻。向世陵认为,宋代理学所创造的"成性"说奠定了理学的本体范畴,是儒学复兴的最重要理论标志;宋代理学本体论的创立使儒学在理论上真正获得了新生。孔令宏认为,宋明理学对道家、道教的吸收,丰富了儒学的体用合一论和功夫境界论,提升了儒学的哲理思辨水平,充实了儒家的思想体系,促进了儒学的新发展。     

A multi-scalar critical analysis of return migration policies in Mexico

Services and resources for migrants returning to Mexico are necessary to ease their transition and “re-integration” into home communities. Policies that do not have a holistic approach can result in serious implications for the social, political, cultural, and health of returnees, receiving families, and communities. This research critically analyses return migration policies in Mexico drawing from the intersectionality-based policy analysis framework and a multi-scalar approach to critically study return migration policies in Mexico. We analysed 20 return migration policies using the principles of the intersectionality-based policy analysis framework. In 2021, we interviewed those impacted by return migration policies in Veracruz, Mexico to gain deeper insights into return migration policies. Women who stayed behind, return migrants, community leaders, and health-care providers were interviewed via phone or face-to-face in Spanish. Information was transcribed verbatim and analysed with the aid of computer-assisted data analysis software and quotes were translated into English. They shed light on two major inequities in policies: (1) the lack of acknowledgement of diversity or return migrants and (2) the exclusion of receiving families and communities from the “re-integration” process of return migrants. Based on the multi-scalar critical policy analysis, return migration policies in Mexico would benefit from a more comprehensive and inclusive approach where the needs of return migrants and community members are protected based on their diversity.     

Effective strategies for socio-educational intervention during the process of transition to adult life of unaccompanied minors from Africa

The arrival of unaccompanied minors from Africa in Spanish territory has been a constant since the last decade of the twentieth century. This migratory phenomenon has forced the child welfare system to attend to thousands of migrant children. The transition to adult life is a decisive stage in overcoming the situation of social exclusion. This research aims to analyse which socio-educational intervention strategies are effective during the process of transition to independent living with unaccompanied minors of African origin. We designed a qualitative research according to the grounded theory, which we divided into two phases. Twenty-nine young people (26 men and 3 women) participated. In phase 1, we performed two focus groups (N = 11), and in phase 2, we conducted longitudinal follow-ups (N = 18) for 24 months through 180 interviews. The results indicate the effectiveness of designing socio-educational accompaniment, prioritizing spaces of trust from which to attain the goals of emancipation. Young people consider effective those strategies that favour their knowledge of the social, labour and legal reality of the host society, designed considering each minor's individualized situation. We concluded that professional involvement acts as a buffer, reducing the bureaucratic obstacles implemented by the Spanish government.     

Parenting practices of Somali immigrant mothers in Alberta

This paper provides insights into the little-explored gendered perspective of the parenting practices of Somali immigrant mothers in a Canadian province (Alberta). We use a critical ethnographic methodology and a transnational feminist framework. Semi-structured interviews were conducted with ten Somali mothers aged 18 to 50. Mothers were interviewed about their parenting practices in a post-migration context, including challenges. Our results show immigrant mothers combine their cultural values with new values from Canada that they find effective. We find gendered differences in how parenting experiences are perceived. Our results suggest the need for anti-racist and culturally safe health, education, and child policies and practices.     

Putting the individual and context back into national human resource development research: A systematic review and research agenda

Conceptualization of national human resource development (NHRD) emphasizes that it is an ongoing development process of the individual that is shaped by context. However, the extant literature has focused primarily on describing and evaluating NHRD policies and interventions in different countries with limited consideration of NHRD across the lifespan and the interaction of life stage with context. Using ecological systems theory (EST) and a lifespan development perspective (LDP), we present a systematic review of the NHRD literature based on 310 sources. We identify key themes and gaps in research across the lifespan and at distinct levels of the ecological system. We build on this review to suggest future research informed by both EST and an LDP. We propose a future research agenda focused on several key areas, including: the developing individual as the primary focus of NHRD; the dynamic relationship between NHRD microsystems and how this evolves over time; the exosystem and macrosystem, which provide the context of the NHRD development experience for the individual over their lifespan; and the imperatives of directing research attention to top-down and bottom-up influences within the ecological system. We also propose three methodological innovations to address many of the questions raised by our review, drawing on national archive databases, the use of historical methods and a focus on longitudinal data analysis. Finally, we highlight the practical implications of our analysis for ecosystem and microsystem NHRD actors.
