Root n consistent and optimal density estimators for moving average processes

Abstract.  The marginal density of a first order moving average process can be written as a convolution of two innovation densities. Saavedra & Cao [Can. J. Statist. (2000), 28, 799] propose to estimate the marginal density by plugging in kernel density estimators for the innovation densities, based on estimated innovations. They obtain that for an appropriate choice of bandwidth the variance of their estimator decreases at the rate 1/ n . Their estimator can be interpreted as a specific U -statistic. We suggest a slightly simplified U -statistic as estimator of the marginal density, prove that it is asymptotically normal at the same rate, and describe the asymptotic variance explicitly. We show that the estimator is asymptotically efficient if no structural assumptions are made on the innovation density. For innovation densities known to have mean zero or to be symmetric, we describe improvements of our estimator which are again asymptotically efficient.     

The White Whale: A Case Study

Towards the end of counselling with Steven, a 13‐year‐old Aboriginal adolescent, he dreamed of being lost at sea and then found by a white whale. The whale carried him to safety; specifically, into the care of his current foster family. This ending is full of symbolism and seems to promise positive and uncomplicated outcomes. However, counselling is rarely straightforward, and this case study is no exception. It explores a complex journey though therapy, full of challenges and discomfort, not only for Steven and myself, but also for the variety of other supportive players in his life. The outcome, although nowhere near as dramatic as his dream, I believe reflects meaningful change for this young man.     

The Effect of Gender Context on Children's Social Behavior in a Limited Resource Situation: An Observational Study

Knowing when to compete and when to cooperate to maximize opportunities for equal access to activities and materials in groups is critical to children's social and cognitive development. The present study examined the individual (gender, social competence) and contextual factors (gender context) that may determine why some children are more successful than others. One hundred and fifty‐six children (M age=6.5 years) were divided into 39 groups of four and videotaped while engaged in a task that required them to cooperate in order to view cartoons. Children within all groups were unfamiliar to one another. Groups varied in gender composition (all girls, all boys, or mixed‐sex) and social competence (high vs. low). Group composition by gender interaction effects were found. Girls were most successful at gaining viewing time in same‐sex groups, and least successful in mixed‐sex groups. Conversely, boys were least successful in same‐sex groups and most successful in mixed‐sex groups. Similar results were also found at the group level of analysis; however, the way in which the resources were distributed differed as a function of group type. Same‐sex girl groups were inequitable but efficient whereas same‐sex boy groups were more equitable than mixed groups but inefficient compared to same‐sex girl groups. Social competence did not influence children's behavior. The findings from the present study highlight the effect of gender context on cooperation and competition and the relevance of adopting an unfamiliar peer paradigm when investigating children's social behavior.     

Democracy and interdependent preferences

In a democracy, the views and wishes of the citizens are to count. The problem here is how this dictum is to be understood. I suggest that a proper analysis requires that each person's preferences be seen in the context of his beliefs concerning the preferences of the others and of the preferences he would have if he held different beliefs. Preferences founded on erroneous beliefs call for special consideration. So also do certain reluctantly held preferences. I propose a decision-policy involving the identification of social equilibria of preference.     

Intergenerational Activities that Promote Engaging Conversations are Preferred among Young and Older Adults

ABSTRACT

Loneliness negatively affects young and older adults. Intergenerational activities foster social connectedness. Using quantitative and qualitative methods, this study explored which intergenerational activities are most enjoyable for college students and retirement community residents. Demographics, loneliness, enjoyment, conversation level, and type of activity were analyzed. The enjoyment and conversation variables were positively correlated (r = .59, p < .001) which was supported by participants’ narratives. Both populations most enjoyed the activities with higher conversation levels, with the first being committees, followed by meals, one on one activities, and transportation. Retirement communities and universities should promote intergenerational activities, which include meaningful conversations.     

The inverse power Lindley distribution in the presence of left-censored data

In this study, classical and Bayesian inference methods are introduced to analyze lifetime data sets in the presence of left censoring considering two generalizations of the Lindley distribution: a first generalization proposed by Ghitany et al. [Power Lindley distribution and associated inference, Comput. Statist. Data Anal. 64 (2013), pp. 20–33], denoted as a power Lindley distribution and a second generalization proposed by Sharma et al. [The inverse Lindley distribution: A stress–strength reliability model with application to head and neck cancer data, J. Ind. Prod. Eng. 32 (2015), pp. 162–173], denoted as an inverse Lindley distribution. In our approach, we have used a distribution obtained from these two generalizations denoted as an inverse power Lindley distribution. A numerical illustration is presented considering a dataset of thyroglobulin levels present in a group of individuals with differentiated cancer of thyroid.     

Embracing inclusive excellence: Asian and Asian American college students

ABSTRACT

This study aims to understand the importance of embracing and promoting inclusiveness in higher education as a path to academic excellence. As student populations become increasingly diverse and higher education faces significant challenges at home and abroad, cultural competence – understanding the specific culture, language, social, and economic status of people-, becomes more important than ever before because a sense of belonging is essential for students. This study is to re-envision diversity and practice our commitment to inclusive excellence-both preparing students with a quality learning opportunity and facilitating a sense of belonging by providing an embracing environment on campus.     

The profile of women who consult midwives in Australia

BackgroundThere is no Australian data on the characteristics of women who consult with midwives.AimTo determine the profile of women who consult midwives in Australia.MethodsThis cross-sectional research was conducted as part of the Australian Longitudinal Study on Women's Health (ALSWH). Participants were the younger (31–36 years) cohort of the ALSWH who completed a survey in 2009, and indicated that they were currently pregnant (n = 801). The main outcome measure was consultation with a midwife.FindingsOf the 801 women who indicated that they were currently pregnant at the time of the survey, 19%, 42%, and 70% of women in the first, second and third trimesters respectively had consulted with a midwife. Women were more likely to consult a midwife if they: also consulted with a hospital doctor (OR = 2.70, 95% CI: 1.66, 4.40); also consulted with a complementary and alternative medicine practitioner (OR = 1.94, 95% CI: 1.25, 3.03); were depressed (OR = 1.84, 95% CI: 1.03, 3.28); constipated (OR = 1.80, 95% CI: 1.04, 3.13); or had been diagnosed or treated for hypertension during pregnancy (OR = 2.78, 95% CI: 1.27, 6.09). Women were less likely (OR = 0.34, 95% CI: 0.21, 0.56) to consult with a midwife if they had private health insurance.ConclusionWomen were more likely to consult with midwives in conjunction with consultations with hospital doctors or complementary and alternative medicine practitioners. Women with private health insurance were less likely to consult midwives. More research is necessary to determine the implications of the lack of midwifery care for these women.     

Prevalence of DSM-IV major depression among Spanish university students

OBJECTIVE: The authors' purpose in this study was to estimate prevalence and correlates of Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), major depressive episodes (MDEs) among Spanish university students. PARTICIPANTS AND METHODS: In October and November 2004, interviewers administered a screening tool to a sample of 554 students aged 18-34 years (65.9% women). RESULTS: The prevalence of MDEs was 8.7% (95% confidence interval = 6.5%-11.3%). The most common symptoms were depressed mood (81.3%) and altered sleep (79.2%). MDEs were more prevalent among women than men (p < .05). The mean number of previous episodes of depression among currently depressed students with previous episodes was 2.2 (SD = 1.4). Of depressed students, 0.6% had considered suicide and 0.2% had attempted suicide. CONCLUSIONS: Depression was highly prevalent among university students. The results suggest the need to develop some type of program or service for university students with the aim of preventing depression and improving their adaptation to university life.
