On Measuring Segregation in a Multigroup Context: Standardized Versus Unstandardized Indices

Social Indicators Research - There has been little discussion about the consequences of using standardized, rather than unstandardized, segregation measures when comparing societies with different...     

Aggregate age-at-marriage patterns from individual mate-search heuristics

The distribution of age at first marriage shows well-known strong regularities across many countries and recent historical periods. We accounted for these patterns by developing agent-based models that simulate the aggregate behavior of individuals who are searching for marriage partners. Past models assumed fully rational agents with complete knowledge of the marriage market; our simulated agents used psychologically plausible simple heuristic mate search rules that adjust aspiration levels on the basis of a sequence of encounters with potential partners. Substantial individual variation must be included in the models to account for the demographically observed age-at-marriage patterns.     

Gender differences in psychosocial predictors of self-perceived health status in the elderly: Evidence from a Brazilian community study

ABSTRACT

This article aims to identify the psychosocial factors associated with self-perceived health status in the Brazilian elderly population and to present differences related to gender. The data were collected by questionnaire, including sociodemographic and behavioral questions, and scales for psychological dimensions. Self-perceived health status is related to level of education, physical activity, and self-efficacy in the total population. Regarding gender differences, self-rated health status among men is related to education level and self-efficacy and in women to level of education, physical activity, social support, and self-efficacy. These results can inform future health promotion interventions.     

An Analysis of the Eco‐Efficiency of Remanufactured Personal Computers and Mobile Phones

Remanufacturing, long perceived as an environmentally friendly initiative, is supported by a number of governments. Yet, the assumption that remanufacturing is desirable to society has never been systematically investigated. In this paper, we examine the effectiveness and eco‐efficiency of remanufacturing in the personal computer and mobile phone industries. We investigate whether remanufacturing substantially reduces the environmental impact, as measured by cumulative energy demand (CED), generated over the life cycles (LCs) of these products, and the size of any reduction. We also examine the relative eco‐efficiency of remanufacturing compared with virgin manufacturing for these two products, where eco‐efficiency includes both willingness‐to‐pay (WTP) for the products as well as the energy consumed in producing the products. Our main findings are the following. One, remanufacturing is an effective way to reduce the total energy consumed during the LCs of personal computers and mobile phones, with one notable exception, when the life spans of remanufactured products are substantially shorter than the life spans of their new counterparts. Two, a remanufactured personal computer or mobile phone is not always more eco‐efficient than a corresponding new product. Three, the WTP for remanufactured personal computers and mobile phones, and consequently, their eco‐efficiencies, are a function of the prices of the correspondent new products at launch and years elapsed between launch and remanufacturing. Four, remanufactured units are sold at a discount relative to the price of new personal computers and mobile phones. Five, on the whole, the market for remanufactured mobile phones is more eco‐efficient than the market for new mobile phones. Six, the market for remanufactured computers is more eco‐efficient than the market for new computers. Lastly, because the group of remanufactured products is heterogeneous, not all remanufactured units are more eco‐efficient than the average new computer and mobile phone. We conclude with a discussion of the impact of our findings on European WEEE and WEEE‐like legislation.

Assessing Adjustment to Aging: A Validation Study for the Adjustment to Aging Scale (AtAS)

Adjustment to aging (AtA) is a multifactor adjustment process with implications on aging well among older adults. The aim of this study was to develop and validate a scale to assess the factors that older adults recognized as indicators of their AtA, with a cross-national comparative perspective towards aging well. Convenience sampling was used to gather questionnaire data, including demographics and the proposed scale. Complete data was available for 1,291 older community-dwelling adults, aged between 75 and 102 years (M = 83.9; SD = 6.68), who represented four different nationalities. Exploratory and confirmatory factor analyses were performed for dimension reduction and exploration of the factorial structure. Data gathered with the 22-items AtA five-factor scale showed overall good psychometric properties (in terms of distributional properties, statistical significant factor weights, factorial, convergent, discriminant criterion and external-related validities, as well as reliability). Five factors were selected for the Adjustment to Aging Scale: (a) sense of purpose and ambitions (b) zest and spirituality; (c) body and health; (d) aging in place and stability; and (e) social support. We present a 22-item scale with five factors for AtA estimation in a cross-national elderly population which produced valid and reliable data for elder persons from four different nationalities. Results showed that this scale is an adequate cross-cultural instrument for research, clinical practice and program development in the health care context. These may benefit from clearly understanding AtA as an important component for reducing health disparities and for aging well, across nationalities.     

Managing Work and Care: A Difficult Challenge for Immigrant Families

This paper explores the strategies used by immigrant families to reconcile work and care for young children in Finland, France, Italy and Portugal. Drawing upon interviews with couples or lone parents who have children below age ten, it shows that immigrant families rely on a diversity of work/care strategies. These strategies include extensive delegation of care (mostly to formal or non‐familial informal care), negotiation of care within the nuclear family (both partners sharing the care responsibilities as well as older child care), mother‐centredness (mothers cutting back on working hours), child negligence (leaving children alone) and the superimposition of care upon work (taking children to work). Almost all immigrant families, but especially first‐generation ones, suffer from the absence of close kin networks to support childcare, strong pressure to work and from work (long or atypical hours) and various integration problems such as social isolation, lack of information on services, and problems with housing. However, our findings show that migration patterns, among other factors, have a significant impact on work/care strategies. Highly qualified “professional migration” is more associated with extensive paid delegation (often private and high‐cost), “marriage migration” with mother‐centredness, and “unskilled worker migration” with low‐cost solutions supplemented by workplace care, older child care and negligence. First‐generation unskilled worker migrant families are more exposed to occupational and residential segregation, atypical working hours, low earnings and difficulties in managing work and care for young children. Findings point to the still weak regulatory function of the different welfare states in the protection of these families.     

Recursive characterization of a large family of discrete probability distributions showing extra-Poisson variation

This article analyses the broad family of discrete probability distributions generated by relating Prob (y) to Prob (y?1), …, Prob (y?n), for some n≥1, through a recursive equation. This family contains the binomial, negative binomial and Poisson distributions as well as the Katz family of distributions. In addition, the suggested family contains some convolutions of Poisson distributions and other generalized distributions, which provide models for Poisson overdispersion or underdispersion.
