Youth and parent perceptions of aftercare supports at discharge from residential care

While much is known about youth struggles after reintegration into the home and community settings following stays in out‐of‐home care, little is known about appropriate supports for aftercare, or parent (see Note ¹ ) and youth perceptions during this critical transition period. This study seeks to begin to address these questions through surveys evaluating youth (n = 48) and parent (n = 48) perceptions of (i) transition planning, family preparedness and aftercare; (ii) youth preparedness for the transition period across major life domains (e.g. education, health care, relationships); and (iii) the importance of specific aftercare supports and services. Results indicate differences between youth and parents on perceptions of need for continued supports, likelihood of participation in aftercare programs; and youth preparedness for success in relationships, family and independent living domains. In contrast, similarities were found on youth and parent ratings regarding the importance of specific services and supports, with both groups indicating supports in education as most important and supports in mental health as least. Study limitations, future research and implications are provided.     

Route first—Cluster second methods for vehicle routing

In this paper we consider route first—cluster second methods for the vehicle routing problem. Extensions to the basic method both to improve its effectiveness and to enable it to cope with practical constraints are described. Computational results are given for the method applied to standard vehicle routing problems drawn from the literature.     

Collaboration with Caveats: Research–Practice Exchange in Planning

Abstract

Researcher and practitioner collaboration in urban planning is both critical to good outcomes and problematic to achieve in reality. Collaboration has the potential for new partnerships, better research problem definition, improved research design and greater impact on practice and policy. However, politics, stakeholder agendas and funding bodies bring pressures and constraints, for which research professionals require a broader set of skills to manage. We examine researcher–practitioner collaboration as part of an action research project on urban greening in Australia. Focusing on a stakeholder engagement workshop, we examine the mechanisms used to overcome barriers to research-practice exchange. We find overt consideration of common barriers to access and use of research when planning collaboration exercises can help facilitate more productive engagement, creating spaces for mutual understanding and generating shared objectives. However, we also find that efforts at collaboration challenge traditional research practices, involve tensions and caveats, and require a different mode of researcher engagement.     

Multiple objective optimization of bluetooth scatternets

Bluetooth technology permits wireless interconnection for local area communication. While the specification defines how up to eight devices can connect using the same radio channel to form a piconet, piconets may overlap, permitting the formation of much larger networks called scatternets. To create connected scatternets, a wide range of decentralized protocols (algorithms) have been proposed. In this paper we address the centralized optimization of topological characteristics that affect scatternet performance. Knowledge of optimized scatternet topology is useful when comparing decentralized protocols and the scatternets they produce. This paper introduces the first multiple objective optimization framework for scatternets, which operates by optimizing node sequencings that represent scatternets. Using NSGA-II, the framework is described, tuned and applied to determine the trade-offs between competing optimization objectives. Finally, the results are used to benchmark the performance and characteristics of four existing protocols from the literature. This research is supported by the UK Engineering and Physical Sciences Research Council (GR/S23155/01).     

Executing Facial Control During Deception Situations

Behavioral countermeasures are the strategies engaged by liars to deliberately control face or body behavior to fool lie catchers. To date research has not shown whether deceivers can suppress elements of their facial expression as a behavioral countermeasure. This study examined whether participants could suppress facial actions such as eyebrow movements or smiles on command when under scrutiny by a lie catcher. The results derived from micro momentary coding revealed that facial actions can be reduced, but not eliminated, and that instructions to suppress one element of the expression resulted in reduction in all facial movement, regardless of veracity. The resulting implications for security contexts are discussed.     

The empirical basis of risk assessment in child welfare: the accuracy of risk assessment and clinical judgment

The importance of risk assessment is juxtaposed with the lack of empirical support regarding the validity of risk inventories. This study compared risk ratings of one risk assessment tool to decisions made by case managers. The researchers sampled 450 children and compared predictive utility of risk assessment to child protection decisions. Risk assessment was consistent with clinical judgment in 74% to 81% of cases, more than previously reported in studies of risk assessment validity. Further analyses identified discriminate functions at the instrument's category and individual-item levels. The results have implications for the validity of the instrument and its utility in child welfare.     

Vehicle routing using fixed delivery areas

In this paper we consider the problem of vehicle routing using fixed delivery areas. This is the problem of splitting the area serviced by a depot into a number of separate subareas—a single delivery vehicle being assigned to each subarea to supply all the customers within the subarea. A heuristic algorithm is developed for the problem based upon an initial allocation of customers to subareas followed by customer interchanges in an attempt to improve the subareas. Computational results are presented for a number of test problems drawn from the literature.     

The dynamic,complex and diverse living and care arrangements of young New Zealanders: implications for policy

The living arrangements of young people in New Zealand are diverse and often complex. In this article we report the range of care and living arrangements of 209 15-year-old New Zealanders, 47 of whom identified as Māori. These young people were participants in the second generation of a cohort study. Data were collected from their parents via a life history calendar and analysed for variety and consistency of care arrangements, household membership and transitions. Few participants had a consistent pattern of parental care arrangements and most had experienced multiple changes in household composition and frequent changes of address. We conclude that the whānau/family lives of many young New Zealanders are complex and dynamic. These observations contrast with the conventional notions of family life that form the basis for New Zealand’s family policies. We argue that social policies and services impacting on young people need to reflect the lived reality of young people if they are to meet young people’s needs.
