More on local influence in pllincipal components analysis

Local influence on the eigenvalues of sample covariance matrices in

principal components analysis is examined for a reasonable modification of Shi's (1997) perturbation scheme, The modification is suggested for samples from populations with both unknown mean vector and covariance matrix. While Shi's detection indexes (1997) consist of only quadratic terms, the modified perturbation scheme leads to detection indexes constituted by both linear and quadratic terms associated with centralized observations. These linear and quadratic terms reflect local influences on the first two sample moments. Examples are investigated based on the two detection indexes.     

Family Structure and Child Well‐being: Integrating Family Complexity

Although children's family lives are diverse, the measurement of children's living arrangements has lagged, focusing on the relationships of children to parents while largely ignoring sibling composition. Using data from the 2008 Survey of Income and Program Participation (N = 23,985) the authors documented patterns of family complexity among a nationally representative sample of children ages 0–17 living in a range of family structures. They also examined the independent and joint associations of family structure and family complexity on child economic well‐being. Family complexity was independently related to economic disadvantage, namely, a lower income‐to‐needs ratio and a higher likelihood of public assistance receipt. The role of family complexity was partially contingent on family structure, with the positive association between family complexity and receipt of public assistance more pronounced for children in families with 2 married biological parents. This study demonstrates the utility of integrating family structure and family complexity in studies of children's well‐being.     

Enabling,structuring and creating elite transnational lifestyles: intermediaries of the super-rich and the elite mobilities industry

ABSTRACT

This article considers how the migration industries lens can be usefully employed in understanding how professional intermediaries enable, structure, and create transnational migration lifestyles of the super-rich. In particular, we examine how intermediaries and their services (1) enable the continued sustenance of transnational migration lifestyles for this group of elites; and (2) structure and create elite transnational lifestyles. This article primarily draws on interviews with professional intermediaries who service the super-rich, and content analysis of their websites and brochures. Inspired by insights from the new mobilities paradigm (and in particular the politics of mobility), we argue for an expanded conceptualisation of the migration industries beyond the literature’s current focus on labour recruitment and migration management. Specifically, we suggest thinking of the migration industries as a collection of actors and services that enable, structure, and create different types of ‘migrants’, their spaces and their highly uneven transnational mobilities – including that of the super-rich and their elite transnational lifestyles. We conclude with suggestions for a research agenda that may help to better understand the role of intermediaries in the creation of differentiated mobilities.     

A paradise for LGBT rights? The paradox of Belgium

How is it that a small country such as Belgium, with its reputation of relative conservatism, has jumped to the forefront of LGBT-friendly nations when it comes to the extension of rights to, and implementation of government policies for, its LGBT population? The analysis offered here focuses on a combination of six causes: the impact of wider secularization processes; the political history and culture of the country; the organization of especially the Flemish LGBT movement and reasons for its political effectiveness; mainstream social trends in national scapegoating hierarchies; the overall media environment; and the window of opportunity opened by the political landslide of 1999.     

A Comparative Analysis of VHA,Non-VHA,and Overall Outpatient Treatment Use Intensity Among Older U.S. Veterans Denied or Awarded VA Service-Connected Disability Compensation

Poorer health is often associated with greater healthcare use among the general population. In contrast, while many veterans denied VA disability compensation ("denied applicants") are as impaired as those awarded VA disability compensation ("awarded applicants"), studies suggest that these veterans may nevertheless utilize less VHA healthcare. Whether they concurrently utilize less non-VHA, and overall healthcare, however, remains a critical, unresolved issue. The 2001 National Survey of Veterans was used to examine VHA, non-VHA, and overall outpatient healthcare treatment use intensity during the previous 12 months among veterans denied or awarded VA disability compensation. Results: Denied applicants were significantly more likely than those awarded to have not used any VHA outpatient healthcare during the previous 12 months (OR=2.45, 95% CI: 1.24, 4.81). Moreover, while not statistically significant, point estimates consistently suggested that denied may have concurrently used more non-VHA, and overall outpatient healthcare than awarded. It appears veterans denied VA disability compensation are forgoing VHA outpatient healthcare services, perhaps in favor of non-VHA outpatient healthcare services. While this result may be consistent with the intent of VA service-connected disability policy, further analysis is necessary to confirm adequate access to healthcare for denied veterans.     

Expanding social health protection in Cambodia: An assessment of the current coverage potential and gaps,and social equity considerations

The Royal Government of Cambodia recently launched its National Social Protection Policy framework to strengthen and expand social security and assistance. To inform social health protection policy, we examine socio-economic survey data and administrative coverage data to assess the coverage potential of existing coverage mechanisms and current gaps; and compare equitable contribution rates. Over 53 per cent of the population currently has no social health protection coverage mechanism, and about 16 per cent of the population who do have access to a mechanism are not yet enrolled. Current expansion efforts focus on the formal employee scheme, primarily benefiting individuals from higher income households. In addition, recent coverage expansion to some informal workers leaves significant gaps, particularly among the informal sector. We find out-of-pocket health care expenditure to be an excessive share of income among lower wealth quintile individuals and conclude they are financially vulnerable. Finally, we illustrate that an equitable approach to individual, monthly health care contributions among the lower three quintiles has a severely limited potential for revenue generation, and collection costs could exceed the amount collected. Therefore, we recommend that vulnerable groups should be exempted from contribution payments as social health protection is expanded.     

Public support for the social rights and social obligations of the unemployed: Two sides of the same coin?

In light of the ever‐growing shift towards activation in European welfare states, the present article examines the relationship between citizens’ welfare generosity (i.e., support for social rights) and welfare conditionality (i.e., support for social obligations) with regard to the unemployed. Using data from the 2014 Belgian National Elections Study, we found that generosity and conditionality appear to be two sides of the same coin. The two factors are negatively correlated, and most of their respective attitudinal drivers are quite similar in strength, yet opposite in direction. In addition to self‐interest and conventionally recognised ideational beliefs, such as egalitarianism and individualism, beliefs about welfare deservingness – an explanatory factor that has remained understudied in the field – are particularly influential in shaping people’s welfare preferences. A stronger emphasis on criteria of deservingness such as control, attitude and reciprocity considerably lowers support for social rights and strengthens support for social duties.

How Are Parental Psychological Control and Autonomy‐Support Related? A Cluster‐Analytic Approach

This study addresses the hypothesis that the relationship between parental psychological control and autonomy‐support depends on how autonomy‐support is conceptualized, that is, in terms of promotion of independence or in terms of promotion of volitional functioning. Questionnaires tapping into psychological control and these two types of autonomy‐support were administered to a sample of 495 emerging adults. Cluster analysis revealed that, whereas parental promotion of independence may or may not co‐occur with psychological control, high parental promotion of volitional functioning systematically goes together with low psychological control and vice versa. Differences between clusters in terms of adjustment were mainly driven by differences in psychological control and promotion of volitional functioning and to a lesser extent by differences in promotion of independence.
