Hellinger distance as a penalized log likelihood

The present paper studies the minimum Hellinger distance estimator by recasting it as the maximum likelihood estimator in a data driven modification of the model density. In the process, the Hellinger distance itself is expressed as a penalized log likelihood function. The penalty is the sum of the model probabilities over the non-observed values of the sample space. A comparison of the modified model density with the original data provides insights into the robustness of the minimum Hellinger distance estimator. Adjustments of the amount of penalty leads to a class of minimum penalized Hellinger distance estimators, some members of which perform substantially better than the minimum Hellinger distance estimator at the model for small samples, without compromising the robustness properties of the latter.     

Notes on likelihood intervals and profiling

In many applications, decisions are made on the basis of function of parameters g(θ). When the value of g(theta;) is calculated using estimated values for te parameters, its is important to have a measure of the uncertainty associated with that value of g(theta;). Likelihood ratio approaches to finding likelihood intervals for functions of parameters have been shown to be more reliable, in terms of coverage probability, than the linearization approach. Two approaches to the generalization of the profiling algorithm have been proposed in the literature to enable construction of likelihood intervals for a function of parameters (Chen and Jennrich, 1996; Bates and Watts, 1988). In this paper we show the equivalence of these two methods. We also provide and analysis of cases in which neither profiling algorithm is appropriate. For one of these cases an alternate approach is suggested Whereas generalized profiling is based on maximizing the likelihood function given a constraint on the value of g(θ), the alternative algorithm is based on optimizing g(θ) given a constraint on the value of the likelihood function.     

Technology as a Weapon in Domestic Violence: Responding to Digital Coercive Control

ABSTRACT

Technology-facilitated domestic violence is an emerging issue for social workers and other service providers. The concept of Digital Coercive Control (DCC) is introduced to highlight the particular nature and impacts of technology-facilitated abuse in the context of domestic violence. While practitioners have become more adept at working with women experiencing DCC, there is still little known about its dynamics and whether this violence requires a change in current service responses. This article explores findings from survey research conducted with 546 Australian domestic violence practitioners about the ways perpetrators use technology as part of their abuse tactics. The findings demonstrate that DV practitioners believe perpetrator use of technology is extensive and has significant impacts on the safety of clients. A major dilemma faced by practitioners is how to promote and facilitate client safety from DCC while still enabling safe use of technology so clients can remain connected to family, friends, and community.

IMPLICATIONS

• The use of digital technology in domestic violence creates a significant practice issue for Australian domestic violence practitioners.

• The development of a practice framework for responding to digital coercive control may assist practitioners to highlight the risks posed by this abuse, while still enabling women and children the freedom to participate in the digital realm.

     

Feelings of Belonging: An Exploratory Analysis of the Sociopolitical Involvement of Black,Latina, and Asian/Pacific Islander Sexual Minority Women

This article compares and contrasts the sociopolitical involvement of Black, Latina, and Asian/Pacific Islander American sexual minority women within lesbian, gay, bisexual, and transgender (LGBT) communities of color. For the analysis, a sample of over 1,200 women from the Social Justice Sexuality project was analyzed. Findings indicate that, for all groups of women, feelings of connectedness to the LGBT community was the most significant predictor of sociopolitical involvement within LGBT communities of color.     

The Politics of Expanding Healthcare Access to the Poor and Informal Sectors

How do the politics of agenda setting and policy adoption operate in the arena of healthcare reform in the industrializing world? Literature on the twenty‐first‐century developmental state emphasizes the role of democratic competition and civil society in causing political parties to take up new agendas, while power resources theory stresses the role of left‐wing political parties and labor unions in policy adoption. Yet, core tenets of these theories have not been considered extensively in light of dynamics in the industrializing world. This article examines the politics of policy adoption in countries that have recently aimed to provide healthcare access and financial protection to the poor and people in the informal sector in Mexico and Turkey. In line with literature on the twenty‐first‐century developmental state, we find democratic competition to play an important role in causing political parties to take up new agendas. However, examination of the cases illuminates surprising dynamics that challenge important elements of sociological theory: right‐leaning political parties played important roles in adoption, while labor unions and left‐wing parties oppose reform in the cases. Public health‐minded physicians leading change teams played important roles in agenda setting and leading the process of implementation.     

Jordan's Public Policy Response to COVID-19 Pandemic: Insight and Policy Analysis

The aim of this study was to gain an understanding of how the Jordanian government has responded and continues to respond to the COVID-19 pandemic. It utilizes the interpretive policy analysis approach through document analysis. The analysis showed that Jordan created social protection policies to assist people who lost their jobs or whose work was suspended due to the coronavirus. The economic policies build solidarity and facilitate the private sector’s recovery. The health care measures firmly applied included lockdown, wearing masks, and restrictions on gatherings and public events. Jordan uses hard power and imposes sanctions on any violation that threatens the lives of others.

     

THERAPIST PHYSICAL ATTRACTIVENESS: AN UNEXPLORED INFLUENCE ON CLIENT DISCLOSURE

Existing research indicates that clients perceive facially attractive therapists as more competent, trustworthy, genuine, and effective than less attractive therapists. No Studies exist to help explain how the therapist's attractiveness influences a client's self-disclosure. Participants (n = 241) were randomly assigned to one of eight experimental groups to test the interaction of the therapist's attractiveness, client's gender, the nature of presenting problem, and the client's comfort with disclosing in a hypothetical couple therapy scenario. Analysis of variance procedures established that most participants reported feeling more comfortable disclosing a benign (communications) problem than a potentially embarrassing (sexual) problem, and more comfortable disclosing problem to an attractive than to a less attractive female therapist. Therapists are encouraged to understand the power attractiveness may have in their own and their client's lives     

“The Price You Pay”: How Female Professional Chefs Negotiate Work and Family

Work–family conflict can act as an important, and gendered, mechanism underlying women’s under-representation in male-dominated occupations. This study uses in-depth interviews to explore the experiences of female professional chefs in order to understand how women in a prestigious, yet male-dominated service occupation manage barriers relating to their balance of work and family responsibilities. Conflict between work and family responsibilities often stemmed from the long work hours expected of chefs and played a role in some of our participant’s decisions to leave kitchen work. Respondents in this study negotiate work–family conflict using three strategies: (1) delaying/forgoing childbearing to succeed as a chef; (2) leaving kitchen work for another job in the culinary field; and (3) adapting either work or family to make the two roles more compatible. Our conclusion discusses the implications of these strategies for gender inequality in the workplace, particularly for women in male-dominated occupations.     

Assessing Overweight,Obesity, Diet,and Physical Activity in College Students

Abstract

The authors surveyed 738 college students aged 18 to 27 years to assess overweight, obesity, dietary habits, and physical activity. They used BMI (body mass index) > 25 kg/m² or BMI > 85th percentile and BMI > 30 kg/m¹ or BMI > 95th percentile to estimate overweight and obesity in those aged < 19 years. To define overweight and obesity in those > 20 years, they used BMI > 25 kg/m² and > 30 kg/m². They found overweight rates of 21.6% using BMI directly and 16.2% using BMI percentile and obesity rates of 4.9% using BMI directly and 4.2% using BMI percentile. More than 69% of the participants reported < 5 servings of fruits and vegetables per day and more than 67% reported < 20 g of fiber per day; participants reported physical activity on fewer than 3 d/wk. Most college students are not meeting dietary and physical activity guidelines, suggesting the need for prevention interventions and increased understanding of overweight in college students.     

Openings,absences and omissions: Aspects of the treatment of ‘race’, culture and ethnicity in British cultural studies

Abstract

British cultural studies has, in an innovative and exciting way over the last three or four decades, opened up spaces for the serious analysis of many aspects of culture, including those inextricably related to questions of ‘race’, ethnicity and subordinated groups in urban environments in Britain. However, there have been a number of weaknesses and omissions with regard to Britain's black, Caribbean-descended population. Some of these are possibly the result of earlier, unresolved theoretical and methodological disputes within the field of cultural studies; others stem, perhaps, from an over-reliance on approaches arising out of youth subcultural analytical frameworks. Consequently, less than the required attention has been paid to the active cultures of achievement developed by the adult, black working-class population of Caribbean descent in Britain from the 1950s to the 1990s.
