Editorial

This paper uses the empirical characteristic function (ECF) procedure to estimate the parameters of mixtures of normal distributions. Since the characteristic function is uniformly bounded, the procedure gives estimates that are numerically stable. It is shown that, using Monte Carlo simulation, the finite sample properties of th ECF estimator are very good, even in the case where the popular maximum likelihood estimator fails to exist. An empirical application is illustrated using the monthl excess return of the Nyse value-weighted index.     

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 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.     

Series estimation of functional-coefficient partially linear regression model

This paper develops an alternative and complement estimation procedure for functional coefficient partially linear regression (FCPLR) model based on series method. We derive the convergence rates and asymptotic normality of the proposed estimator. We examine its finite sample performance and compare it with the two-step local linear estimator via a small scale Monte Carlo simulation.     

Perceptions of emerging adults who accessed residential treatment and entered a parental role

Youth who accessed residential mental health treatment (RT) continue to experience challenges related to their emotional and behavioral disorders, and continue to struggle in several life domains. Some of these youth also become parents. The purpose for this report was to explore the perceptions of emerging adults who accessed RT as a child or youth, and who became parents, about their life domains. These participants (n = 12) reported continued challenges in several domains of living, and some reported that impending parenthood helped motivate them to improve their behaviors. Many reported continued reliance on previous social workers. Implications for practice are discussed.     

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     

Gambling Responsibly: Who Does It and To What End?

Numerous responsible gambling (RG) strategies are promoted to assist consumers to “gamble responsibly”. However, consumer adoption of RG strategies, how this varies by gambler risk group, and whether usage is associated with non-problematic gambling are largely unknown. This study aimed to (1) determine how use of RG-related strategies differs amongst regular gamblers by gambler risk group; and (2) identify RG-related strategies whose usage predicts non-problem/low risk gambling. Regular Australian gamblers on high-risk products (N = 860), recruited through gambling venues and an online wagering operator, were surveyed about their use of RG strategies promoted on the website of their jurisdiction’s main RG agency. Knowledge of RG strategies was reasonably high amongst all gambler risk groups, but lower-risk groups were more likely to use RG strategies. A logistic regression correctly predicted 82.1 % of lower-risk gamblers and 77.2 % of higher-risk gamblers. Predictors of lower-risk gambling included: greater confidence in their understanding of RG; endorsement of lower gambling expenditure and frequency limits; fewer erroneous gambling beliefs; being less likely to gamble to win money, challenge their skills/beat the odds, or forget about worries and stresses; and being more likely to gamble for pleasure/entertainment. Lower-risk gamblers were more likely to set a money limit in advance of gambling and to balance their gambling with other activities. These findings contribute to understanding which strategies are favoured by different risk groups, and which are associated with safer levels of gambling. They can guide consumer information aimed at enhancing RG consumption and future research on RG consumption.     

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.     

Infants’ Response to Pictures of Impossible Objects

Previous work has shown that 4‐month‐olds can discriminate between two‐dimensional (2D) depictions of structurally possible and impossible objects [S. M. Shuwairi (2009), Journal of Experimental Child Psychology, 104, 115; S. M. Shuwairi, M. K. Albert, & S. P. Johnson (2007), Psychological Science, 18, 303]. Here, we asked whether evidence of discrimination of possible and impossible pictures would also be revealed in infants’ patterns of reaching and manual exploration. Nine‐month‐old infants were presented with realistic photograph displays of structurally possible and impossible cubes along with a series of perceptual controls, and engaged in more frequent manual exploration of pictures of impossible objects. In addition, the impossible cube display elicited significantly more social referencing and vocalizations than the possible cube and perceptual control displays. The increased manual gestures associated with the incoherent figure suggest that perceptual and manual action mechanisms are interrelated in early development. The infant’s visual system extracts structural information contained in 2D images in analyzing the projected 3D configuration, and this information serves to control both the oculomotor and manual action systems.
