Route‐Independent Analysis of Available Capacity in Flexible Manufacturing Systems

In a job shop, because of large setup times, each operation is assigned to only one machine. There is no alternative routing. In a flexible manufacturing system, each manufacturing operation can often be performed on several machines. Therefore, with automated equipment, the capacity of a machine to perform certain operations is not independent of the capacity of other machines. Often, however, operations managers can use a route‐independent answer to production planning questions. For example, how much can be produced of a certain part type and when are important capacity questions in business negotiations, when the detailed routing and scheduling are not yet of interest or cannot be known. This paper provides a mathematical model for the route‐independent analysis of the capacity of flexible manufacturing systems based on a concept of operation types. An example is provided both to illustrate the use of operation types and to highlight the differences between the traditional route‐dependent and the proposed route‐independent formulations of capacity constraints. Some computational results are also given. Finally, a sensitivity analysis is developed to analyze the feasibility of production plans when production requirements and machine capacities can change.     

Iraqi refugees and the humanitarian costs of the Iraq war: What role for social work?

Harding S, Libal K. Iraqi refugees and the humanitarian costs of the Iraq war: what role for social work? The US‐led invasion and war in Iraq has created one of the most significant refugee crises in recent decades. International nongovernmental organizations have partnered with local organizations in Jordan and Syria to provide humanitarian aid to some two million displaced Iraqis. Field research indicates that, as with other humanitarian crises, few trained social workers have contributed to policy and practice with displaced Iraqis. The case of Iraq provides an opportunity to consider how the social work profession can shape comprehensive global refugee policies and programs. This role is appropriate, given mandates for the profession to promote social justice and human rights. Using the case of Iraqi displacement, we illustrate the complexities of humanitarian services provision and the need for trained social workers to participate in humanitarian relief and development programs. We argue that a variety of social work institutions and actors should become more robust advocates for shaping just refugee policy and practice.     

Better educational inclusion of migrant children in urban schools? Exploring the influences of the population control policy in large Chinese cities

The educational inclusion of rural–urban migrant children in Chinese urban schools has been promoted in the past decades. This paper provides a contextualized interpretation of recent policy developments governing large Chinese cities and evaluates its impact upon the status of migrant children's education. Drawing on data collected from 1,331 migrant children in urban inclusive schools, this study compared current migrant children's family backgrounds and psychological sense of belonging at school in relation to educational outcomes at the primary education level. Results showed that migrant children's socioeconomic status (SES) levels were slightly higher than their counterparts in inclusive schools and a salient SES stratification of migrant students was found. This correlates with students’ reports of fewer incidences of discrimination than hypothesized. Furthermore, capital in migrant families was positively associated with the psychological sense of belonging and academic achievement. These results reveal a significant change to migrant students’ SES as a result of the recent population control policy pertaining to China's large cities since 2014. Implications for research and educational practice, especially with at‐risk migrant students of low‐SES, are discussed.     

Older bisexual people: Implications for social work from the ‘Looking Both Ways’ study

There is a growing social work literature about lesbian, gay, bisexual, and transgender (LGBT) older people. However, research and guidance are predominantly based on the experiences of older gay men and, to a lesser extent, older lesbians. There is little to help practitioners work with older bisexual people. The Looking Both Ways study aimed to contribute to this gap in knowledge. We undertook in-depth purposely sampled qualitative interviews with 12 people aged over 50, all of whom have bisexual relationship histories and half of whom also currently identify as bisexual. There were three main findings. First, biphobia (prejudice against bisexual people) impacts on older people with bisexual histories in ways that may affect their well-being in later life. Second, concerns around receiving care are similar in some ways and different in others from the concerns of lesbians and gay men. Third, people with bisexual relationship histories may have developed strong support networks and resilience, factors that may be very beneficial in later life. Three recommendations for social work professionals were identified: 1) understand biphobia, 2) recognize the legitimacy of concerns about receiving care, and 3) ask about support networks rather than assuming family support.     

Differential Relationships Between Religiosity,Cigarette Smoking,and Waterpipe Use: Implications for College Student Health

Abstract

Objective: Using a framework informed by problem behavior theory, ¹ Jessor, R and Jessor, S. 1977. Problem Behavior and Psychosocial Development: A Longitudinal Study of Youth, New York, NY: Academic Press.  [Google Scholar] the authors examined differential relationships between religiosity and the frequency of cigarette and waterpipe tobacco smoking. Participants: Six hundred fourteen individuals beginning their freshman year at a large, public, midwestern university. Methods: Paper-and-pencil surveys were administered to students who attended freshman orientation. Electronic surveys were sent to students who did not attend orientation. Results: Although a latent, generalized religiosity factor was negatively associated with frequency of cigarette smoking, there was no such relationship for frequency of waterpipe use. Conclusions: Conceptualizing waterpipe tobacco smoking in terms of problem behavior theory may be inappropriate, given its lack of association with religiosity. These results may reflect the perception that waterpipe use is a more socially acceptable form of tobacco use that is less harmful to health than cigarette smoking, despite medical evidence to the contrary. Implications for prevention and intervention are discussed.     

Man Up Monday: An integrated public health approach to increase sexually transmitted infection awareness and testing among male students at a midwest university

ABSTRACT

Objective: This campaign sought to (a) increase awareness of sexual health and chlamydia testing; (b) motivate students, particularly sexually active men who do not pursue regular sexually transmitted infection (STI) testing, to get tested; and (c) improve the capacity of the student health center to provide free chlamydia testing and treatment for all students. Participants: Students enrolled at a 4-year public research university (N = 333). Methods: Collaborative partnerships formed the foundation of a campus marketing and testing campaign, with treatment for students testing positive for chlamydia. Results: A total of 333 students were tested over 5 consecutive Mondays, showing a chlamydia incidence of 9.6%. The incidence for females and males were 8.6% and 10.8%, respectively. Conclusions: The campaign was effective in reaching men, an at-risk population not traditionally emphasized in STI testing.     

Echoic and Self-Echoic Responses in Children

Eleven typically developing children were assessed on the accuracy of prompted self-echoic responses following a 5-s delay from their initial echoic response, replicating procedures in Esch, Esch, McCart, and Petursdottir (2010) that compared discrepancies between echoic and self-echoic scores of autistic and typically developing children following a 2-s delay. We compared the two studies in terms of age, level tested, and echoic/self-echoic discrepancy scores. Age and test level differences were found to be statistically significant. Results are discussed in terms of discrepant self-echoic performance and self-echoic rehearsal as it relates to participant age, test level, motivating variables, and the development of complex behavior.     

Comparing Acquisition of Exchange-Based and Signed Mands With Children With Autism

Therapists and educators frequently teach alternative-communication systems, such as picture exchanges or manual signs, to individuals with developmental disabilities who present with expressive language deficits. Michael (1985) recommended a taxonomy for alternative communication systems that differentiated between selection-based systems in which each response is topographically identical (e.g., card selection and exchange systems) and topography-based systems in which each response is topographically distinct (e.g., signed language). We compared the efficiency of training picture exchanges and signs with 3 participants who presented with severe language deficits; all participants acquired the picture-exchange responses more readily.     

Essential Data Elements for Reporters of Elder Abuse

Most states' adult or elder protective services and aging agency personnel prepare annual reports about their protective services. These reports vary by state and have different terms for the reporter of abuse. Reviewing annual reports from 46 states and the District of Columbia, 248 different terms were used for the reporter of abuse. To develop essential data elements for reporters of abuse, a literature search, a compilation of state elder abuse annual report list of abuse reporters, and a sorting exercise were conducted. Eleven terms were recommended for the different reporters of abuse, encouraging all state administrators and caseworkers to reach consensus to standardize the language.     

Child Welfare and Juvenile Justice: Examining the Unique Mental Health Needs of Girls

This study investigated the prevalence of mental health problems among girls who are involved in child welfare or juvenile justice systems. The sample consisted of 1,193 girls ranging in age from 4 to 18, the majority (82.3%, n = 982) of which were older than age 12. Differences based on race/ethnicity and developmental age groups were examined. Consistent with other research, this study found that the mental health needs of girls involved in the child welfare or juvenile justice systems are several times higher than in the general population. Intervention approaches must be developed that take into consideration differences in gender, age, and racial and ethnic group.
