Step by step: tenant accounts of securing and maintaining quality housing with a housing choice voucher

Previous research on renters’ experiences in the Housing Choice Voucher (HCV) program is robust, but much of it has been conducted in the context of mobility interventions providing added resources. In contrast, this study focuses on HCV renters’ experiences searching for housing without the support of a mobility intervention. In semistructured interviews, 34 HCV renters describe their housing search processes and outcomes. We find that renters struggle to secure housing in their preferred neighborhoods due to limited information and financial costs such as application fees and security deposits. Discussion focuses on practice and policy reforms that might support greater housing choice.     

Equal Processing Time Bicriteria Scheduling on Parallel Machines

We consider the problem of scheduling jobs on parallel, identical machines so as to minimize a primary and a secondary criteria. All the jobs are assumed to have identical processing times. Polynomial time algorithms, that generate optimal solutions, are presented for various combinations of primary and secondary criteria.     

Working HIV care-givers in Botswana: Spill-over effects on work and family well-being

Families provide most of the care to the tens of millions of HIV-infected and -affected in Africa. Little research exists on how care-givers balance the demands of holding a job with providing care for those who have become ill or orphaned by HIV/AIDS. Using data from a large survey administered to 1,077 working care-givers in Botswana, we compared the experience of HIV care-givers with non-HIV care-givers. Compared to non-HIV care-givers, HIV care-givers were more likely to worry about routine childcare (44% vs. 31%) and sick childcare (64% vs. 49%). Amongst those working far from home, more HIV care-givers were concerned that their children were not receiving adequate academic support (39% vs. 20%) and emotional support (57% vs. 33%). Parents who were HIV care-givers were less able to spend time with their own children. Children of HIV care-givers were more likely to have physical, mental and academic problems. While HIV care-givers were more likely to take leave from work for care-giving (53% vs. 39%), and for longer periods of time (13 vs. 7.6 days), this leave is more likely to be unpaid. Strategies to support those directly and indirectly affected by HIV and to avoid economic responsibility are discussed.     

Still connecting the dots: An investigation into infants' attentional bias to threat using an eye-tracking task

An attentional bias toward threat has been theorized to be a normative aspect of infants' threat and safety learning, and an indicator of risk for internalizing psychopathology in older populations. To date, only four studies have examined this bias using the dot-probe task in infancy and the findings are mixed. We extended the literature by examining patterns of attention to threat in a culturally and linguistically diverse sample of infants aged 5–11 months old (N = 151) using all measures previously employed in the infant dot-probe literature. Given that an attentional bias toward threat is associated with higher risk of developing anxiety disorders later in life, we also examined how negative affect—an early correlate of later anxiety disorders—is related to attentional bias toward threat in infancy. This study was the first to use a consistent measure of negative affect across the whole sample. An eye-tracking dot-probe task was used to examine attentional bias toward threat (i.e., angry faces) relative to positive (i.e., happy faces) stimuli. Results showed that an attention bias to threat was not characteristic of infants at this age, and negative affect did not moderate the putative relationship between attention and emotional faces (angry, happy). These findings therefore suggest that attention biases to socio-emotional threat may not have emerged by 11 months old.     

An Integrated Approach for Modeling Sustainability Risks in Freight Transportation Systems

Integrating sustainability into freight transportation systems (FTSs) is a complex and challenging task due to the sheer number of inherent sustainability risks. Sustainability risks disrupt the economic, social and environmental objectives of freight operations and act as impediments in the development of sustainable freight transportation systems. The area of sustainability risk management is still unexplored and immature in the operational research domain. This study addresses these research gaps and contributes in a threefold manner. First, a total of 36 potential sustainability risks related to FTSs are identified and uniquely classified into seven categories using a rigourous approach. Second, the research proposes two prominent perspectives, namely, ontological and epistemological perspectives to understand risks and develops a novel framework for managing sustainability risks in FTSs. Third, a novel approach by integrating fuzzy evidential reasoning algorithm (FERA) with expected utility theory is developed to quantitatively model and profile sustainability risk for different risk preferences, namely, risk-averse, risk-neutral, and risk-taking scenarios. The proposed FERA is a flexible and robust approach, which transforms the experts’ inputs into belief structures and aggregates them using the evidence combination rule proposed in Dempster–Shafer theory to overcome the problem of imprecise results caused by average scoring in existing models. A sensitivity analysis is conducted to demonstrate the robustness of the proposed model. Unlike conventional perception, our study suggests that most of the high priority sustainability risks are behaviorally and socially induced rather than financially driven. The results provide significant managerial implications including a focus on skills development, and on social and behavioral dimensions while managing risks in FTSs.

Motor variability--an important issue in occupational life

Several recent reviews have reported that 'repetitive movements' is a risk factor for occupational musculoskeletal disorders (MSD) in the neck, shoulder and arm regions. More variation in biomechanical exposure is often suggested as an effective intervention in such settings. While increasing variation using extrinsic methods like job rotation may not always be possible in an industrial context, the intrinsic variability of the motor system may offer an alternative opportunity to increase variation. Motor variability (MV) refers to the natural variation in postures, movements and muscle activity observed to different extents in all tasks. The current review explores the state of the art in MV research from motor control, sports and occupational biomechanics literature to answer whether MV is important to consider in an occupational context, and if yes, whether this literature stimulates further studies to test if MV can be manipulated as a deliberate intervention for increasing biomechanical variation without jeopardizing production.     

Mediating Feminism

This study attempts to understand how A-level media studies plays a role in girls' navigation through today's postfeminist media culture. Of particular interest in this article is to identify the ways in which students cultivate a feminist (as opposed to postfeminist) sensibility through their experiences in media studies. Classroom observations were conducted across three UK institutions. Further data were collected by means of semi-structured interviews with fifteen girls and four educators. Findings suggest that students adopt a feminist voice when discussing young girls' relationships with media and when articulating their own desires for a career and for equality in the domestic sphere. A postfeminist voice, however, persists in their understandings of natural sexual difference and the reclamation of adult women's sexual subjecthood. Interviewees express hesitation to adopt the feminist label, and educators rarely address feminism as a main topic in the classroom. Though the media studies classroom is a site which improves the awareness of existing gender inequalities, suggestions for updated classroom content are considered to improve the development of girls' feminist sensibility, including a clearer and more detailed exploration of transitions from girlhood to womanhood, and a clarification of the media's role in naturalising gender differences.
