A Review of the packing problem

The random pazking problem has been of interest to inoestigsccrs in seveal disciplines , Physical chemists have investigaced such models in two and three dimensions, Because of aralytical difficulties, one-dimensional analogacs have been explored and theseare referred to as the parking problem, A number of results areexplored and attempts are made to tie them together, Applicationsare also highlighted.     

Prevalence of unprotected sex and HIV‐antibody testing among gay,lesbian, and bisexual youth

Prevalence of unprotected sex and HIV‐antibody testing were examined in a sample of Southern gay, lesbian, and bisexual youth (n = 117). In addition, a new measure was tested in terms of its ability to distinguish youth who obtain HIV‐antibody testing from those who do not. Data were collected at a conference for these youth, as well as at a Gay and Lesbian Community Center in a Southeastern metropolitan area. Youth reported engaging in a wide range of risk behaviors, yet less than one half had been tested for HIV. Factor analysis was conducted for the new measure, which assessed beliefs about HIV testing in youth, and each factor was significantly different for youth who had been tested compared to those who had not. Gay, lesbian, and bisexual youth were at high risk for HIV infection and were often untested for HIV antibodies.     

Individual and Familial Determinants of Married Arab Israeli Women's Labor Force Participation: Trends of Change and Stability

Although the Arab population in Israel has undergone important economic and social changes in the past decades, the labor force participation of Arab women, particularly married women, has remained limited. This study uses census data to learn about the individual and familial factors associated with the entry into paid work of married Arab women and examines the extent to which these factors have changed over time. A major advantage is that the study distinguishes between the Muslim, Christian, and Druze populations, who markedly differ in their demographic, social, and cultural characteristics. Results from logistic regression models and standardization analyses reveal that the growth in employment experienced by Arab women was associated with the increasing education of both wives and husbands. However, the returns to education significantly decreased over time, particularly among Druze women, suggesting it has become more difficult for highly educated women to find employment. Results further show that the growth in employment experienced by Muslim and Christian women was related both to a decline in fertility and to a decrease in the negative returns to having children. Overall, findings underscore the structural barriers that limit Arab Israeli women's employment opportunities and raise concerns about their future occupational prospects.     

Differences in Adolescent Experiences of Polyvictimization and Suicide Risk by Sexual Minority Status

Sexual minority adolescents (SMA) report more suicide risk behaviors than heterosexual adolescents. Polyvictimization (co‐occurrence of multiple types of victimization) may be an important, underresearched correlate of this disparity. With the 2017 national Youth Risk Behavior Survey (N = 13,179), national estimates of polyvictimization and suicide risk were assessed among high school students by sexual minority status (SM vs. heterosexual), and multivariate relationships between sexual minority status, polyvictimization, and suicide risk were tested. Additionally, risk profiles of those who experienced polyvictimization (2 + types of victimization; n = 1,932) were compared across sexual minority status. Results confirm that SMA are more likely to experience polyvictimization than heterosexual adolescents (31.8% v. 12.9%, respectively); however, also indicate that polyvictimization does not fully explain elevated suicide risk among SMA.     

The Socio-economic Integration of the Ethiopian Community in Israel

Using data from the 1995 Israeli Census of Population, this study examines the demographic, human capital, and labour force characteristics of the Ethiopian community in Israel and its determinants of employment. The results provide strong evidence for the overall disadvantaged socio‐economic status of the Ethiopian community and reveal substantial gaps in educational and occupational attainment between Ethiopian Israelis and members of other ethnic groups in Israeli society. Ethiopian Israelis have substantially lower levels of education, lower employment rates, and are more likely to have low‐skilled occupations. However, multivariate analyses show that the determinants of employment of Ethiopian Israelis are relatively similar to those of other ethnic groups. Education and veteran status are found to be especially important factors associated with increased odds of employment. Although the rates of return from education are lower among Israelis of Ethiopian origin compared to other ethnic groups, this study suggests that education constitutes the major avenue for upward mobility in the Ethiopian community. Nevertheless, considering their current disadvantaged position, the question of whether Ethiopian immigrants will manage in the long run to climb up the socio‐economic ladder and significantly improve their status, or whether they run the risk of becoming a marginalized ethnic group in Israeli society, remains a major concern. Implications for the formation of a new cleavage in Israeli society and the emergence of a stratification system based on race are discussed.     

An Approach to Assessing the Impacts of Incident-Free Transportation of Radioactive Materials: I. Air Transportation

Annual radiation doses and risks to passengers and crew are calculated for shipments of radioactive materials in passenger aircraft under accident-free and incident-free conditions (i.e., under normal transportation conditions). The 1982 database developed by Sandia National Laboratories is used, and calculations are made using RADTRAN 4.0. This paper is one of two papers estimating radiological risk associated with incident-free transportation of radioactive materials.     

Challenging Endings: First Year MSW Interns’ Experiences with Forced Termination and Discussion Points for Supervisory Guidance

Every year, students prematurely end their work with some clients due to the completion of their internship, rather than the client’s achievement of goals and thus a more natural endpoint of treatment. It is important to understand students’ experiences with forced termination to provide them with the necessary knowledge, skills, and support to optimally manage this complex phenomenon. This paper reviews the social work literature on forced termination arising from the ending of students’ internships and presents, in their own words, the experiences of four first-year MSW interns with forced termination. Finally, based on the literature and as borne out by these students’ experiences, some areas for discussion and reflection between interns and their supervisors in handling forced termination are offered.
