Likelihood estimation for longitudinal zero-inflated power series regression models

In this paper, a zero-inflated power series regression model for longitudinal count data with excess zeros is presented. We demonstrate how to calculate the likelihood for such data when it is assumed that the increment in the cumulative total follows a discrete distribution with a location parameter that depends on a linear function of explanatory variables. Simulation studies indicate that this method can provide improvements in obtaining standard errors of the estimates. We also calculate the dispersion index for this model. The influence of a small perturbation of the dispersion index of the zero-inflated model on likelihood displacement is also studied. The zero-inflated negative binomial regression model is illustrated on data regarding joint damage in psoriatic arthritis.     

An Empirical Analysis of Strike Durations in Ghana from 1980 to 2004

Abstract. This paper provides a seminal analysis of strike activity for an African country in investigating the determinants of strike durations in Ghana over the period 1980–2004. The empirical approach uses a set of well‐known parametric accelerated failure time strike duration models. There is a broad consensus among the different empirical models about the role exerted on average strike duration by strike size, the rate of inflation, enterprise ownership, and political governance. However, evidence on the relationship between strike durations and business cycle activity in Ghana is less clear‐cut.     

Perceived Family Functioning and Family Resources of Hong Kong Families: Implications for Social Work Practice

This article reports the results of a telephone survey (n = 1,015 respondents) that aims to identify the perceived general family functioning and family resources of Hong Kong Chinese families and their linkage to each other in a rapidly transforming society. The perceived general family functioning of the respondents was average, and the five types of family resources—time, income, human capital, psychological capital, and social capital—of the respondents ranged from average to good. The following family resource domains, in descending order, have accounted for significant variance in perceived general family functioning: income, time spent with family, stress coping efficacy, religion, and satisfaction with the living environment. Our findings provide empirical support for policy formulation and social work practice.     

Divorce Insurance: Mitigating the Adjudication Period Financial Crisis

Divorce can subject both parties in a troubled marriage to one of the most emotionally and financially trying periods they will experience in their life. Much attention has been given toward life after divorce—either the decisions such as custody of children that will influence this, or the changed circumstances that both parties will find themselves facing. Yet the period from filing to final grant of a divorce poses additional challenges on top of the emotional uncertainties suffered during this period. Total household expenses might double or triple as a result of spouses seeking separate residences, legal bills, added travel, and other expenses forced by a divorce. At the same time, disruptions in one's personal life due to a divorce can disrupt job performance, and in certain situations, even make it difficult or impossible to work; household income can drop accordingly. This article proposes a workable insurance solution to alleviate this second lesser known challenge that a changed financial situation imposes on couples during the divorce adjudication period.     

Child Advocacy Center Based Group Treatment for Child Sexual Abuse

The present study examines initial symptom presentation among participants, outcomes, and social validity for a group treatment for child sexual abuse delivered at a child advocacy center. Participants were 97 children and their nonoffending caregivers who were referred to Project SAFE (Sexual Abuse Family Education), a standardized, 12-week cognitive-behavioral group treatment for families who have experienced child sexual abuse. Sixty-four percent of children presented with clinically significant symptoms on at least one measure with established clinical cutoffs. Caregivers of children who presented with clinically significant symptoms reported more distress about their competence as caregivers. Children who presented as subclinical were more likely to have experienced intrafamilial sexual abuse. Posttreatment results indicated significant improvements in functioning for all children who participated in treatment, with greater improvements reported for children who initially presented with clinically significant symptoms. Overall, the program was rated favorably on the posttreatment evaluation of social validity.     

Using experiential knowledge to understand urban rat ecology: A survey of Canadian pest control professionals

Rats (Rattus rattus and Rattus norvegicus) are among the most prolific and widespread urban pest species in the world. However, there is relatively little contemporary data regarding the ecology of rats in urban centers, preventing the development of effective strategies for urban rat management. Practical constraints associated with field studies suggest the need for more efficient methods of data collection, one of which could involve pest control professionals, who have considerable experiential knowledge of urban rats. The objective of this study was to gather data regarding urban rat ecology through a survey of Canadian pest control professionals and to determine whether such a survey could be useful for the collection of ecological data regarding pest species. Survey results suggested that rat infestations fluctuate seasonally and that there are a variety of environmental factors that may attract rats, particularly exposed garbage, abandoned buildings, and compost. Respondents suggested that rat infestations are most frequent and/or severe in residential areas, commercial areas dealing with food, as well as in neighborhoods of low socioeconomic status. The majority of respondents believed that rats pose at least a moderate health risk to the general public and to themselves, and they also believed that although poison baiting is the cheapest and easiest method of rat control, environmental modification is the most effective way to control rat infestations in the long term. Despite issues with low response rates, these results suggest that pest control professionals may be a valuable source of data regarding urban pest species.     

An Examination of Listening Concepts in the Healthcare Context: Differences Among Nurses,Physicians, and Administrators

This study explores the perceived conceptualizations of listening in a healthcare context. The review of literature focusing on communication and listening in healthcare supports the belief that listening is an essential element in patient satisfaction. This study sought to determine which activities physicians, nurses and healthcare administrators perceive as similar or identical to listening. A survey of 203 health care professionals, using a web-based version of the Imhof-Janusik Listening Concepts Inventory (Imhof and Janusik, 2006 Imhof, M. and Janusik, L. A. 2006. Development and validation of the Imhof-Janusik listening concepts inventory to measure listening conceptualization differences between cultures. Journal of Intercultural Communication Research, 35(2): 79–98. [Taylor &; Francis Online] , [Google Scholar]) was completed. The results suggest the listening conceptualizations vary among physicians, nurses, and administrators with administrators exhibiting the most flexibility in their conceptualization of listening. It is concluded that these conceptualizations may play a critical role in the behaviors displayed by nurses, physicians and hospital administrators.     

Cultural integration through shared learning among resettled Bhutanese women

ABSTRACT

The multidimensional needs of recently resettled refugees have been well documented and range from elevated rates of mental illness and health care challenges to difficulties accessing resources due to language and literacy barriers. These factors are largely responsible for the challenges resettled refugees face in acquiring and maintaining stable employment. It is possible that achieving financial stability through steady employment and purposeful money management may alleviate some stressors associated with the resettlement process, though research in this area that is specific to refugees is in its infancy. What is clear, however, is that a traditional approach to mental health treatment (i.e., therapy in a traditional office setting) may lack effectiveness because of the lack of attention to extraneous stressors such as poverty, transportation, and language and literacy challenges that impact resettled refugees. The purpose of this study was to qualitatively assess the impact of a group-based financial education course and social enterprise on the self-reported mental health (i.e., post-traumatic stress symptoms, depression, anxiety, and somatization) of Bhutanese refugee women resettled in the United States. The study also sought to evaluate the acceptability and overall satisfaction with various components of the intervention. This qualitative study was a follow-up to a larger quantitative study that included 65 Bhutanese women who were resettled to the southwestern United States by a large resettlement agency. The results of this study offer insights into the lived experiences of Bhutanese refugees in the United States, particularly related to cultural integration bolstered by group-based education and shared learning opportunities.
