Abstract
Planning systems are only as good as their interface with the distribution function. If distribution is having an adverse effect on the overall logistics system, then we have a “systems gap”. What is then needed is the use of distribution requirements planning (DRP), a powerful method with which to integrate the logistics systems of organisations.

Abstract
There have always been traditional differences between the various regions of the British Isles. For example, meat consumption is greater in the North than the South; most families take some meat at every meal and this extends to the children. The North is the home of the savoury meat products, eg., faggots, rissoles and similar preparations and a high meat content for such foods as sausages is expected; between 80 and 90% with the cereal only present for binding purposes. Present minimum meat contents would be considered a swindle, also the nature of the lean meat and the lean meat/fat ratio. The high water content similarly would have been unacceptable.

Abstract
Satisfying target markets is a major strategic purpose of all organisations. Logistics management, however, often encounters difficulty in serving individual customer groups. The target market or market segment is the building block of corporate strategy, the focus of both marketing and logistics efforts. Marketing focuses narrowly on specific sets of customers who respond in a similar way to the marketing mix. Logistics strategy, on the other hand, stresses the integration of material and product flow through the organisation as a single unit. The common bond lies in meeting the needs of these groups.

Abstract
Purpose
The purpose of this paper is to present the implementation of a balanced domain decomposition approach for the numerical simulation of large electro-quasistatic (EQS) systems in biology. The numerical scheme is analyzed and first applications are discussed.
Design/methodology/approach
The scheme is based on a finite element discretization of the individual domains obtained by decomposition and a physically consistent inter-domain coupling realized via Robin boundary conditions. The proposed algorithms can efficiently be implemented on a highly parallelized computing grid.
Findings
The feasibility and applicability of the method is proven. Further, a couple of technical details are found that increase the efficiency of the method.
Originality/value
The presented method offers an enhanced geometrical flexibility and extensibility to simulate larger cell systems with higher model resolution compared to other methods presented in the literature. The presented analysis provides an understanding of the balanced coupling scheme for large EQS systems.

The purpose of this paper is to present topological derivatives-based reconstruction algorithms to solve an inverse scattering problem for penetrable obstacles.
Abstract
Purpose
The purpose of this paper is to present topological derivatives-based reconstruction algorithms to solve an inverse scattering problem for penetrable obstacles.
Design/methodology/approach
The method consists in rewriting the inverse reconstruction problem as a topology optimization problem and then to use the concept of topological derivatives to seek a higher-order asymptotic expansion for the topologically perturbed cost functional. Such expansion is truncated and then minimized with respect to the parameters under consideration, which leads to noniterative second-order reconstruction algorithms.
Findings
In this paper, the authors develop two different classes of noniterative second-order reconstruction algorithms that are able to accurately recover the unknown penetrable obstacles from partial measurements of a field generated by incident waves.
Originality/value
The current paper is a pioneer work in developing a reconstruction method entirely based on topological derivatives for solving an inverse scattering problem with penetrable obstacles. Both algorithms proposed here are able to return the number, location and size of multiple hidden and unknown obstacles in just one step. In summary, the main features of these algorithms lie in the fact that they are noniterative and thus, very robust with respect to noisy data as well as independent of initial guesses.

Abstract
Given their history of preparing African Americans, ethnic minorities, and first-generation college students for careers in education, the culture and traditions of Historically Black Colleges and Universities (HBCU) can provide insight into the preparation of diverse physical educators for the cultural, linguistic, and ethnic diversity in today’s American K-12 schools. As such, this chapter will present practical findings from an ethnographic study of a historically Black urban Physical Education Teacher Education (PETE) program with a large native Spanish-speaking population. Specifically, we focus on the concepts of cultural sustainment and code-switching as strategies used by teacher educators to promote bilingualism and biculturalism. To achieve this, we highlight the relationship among institutional, programmatic, and classroom cultures for the cultural sustainment and development of preservice physical educators. According to Paris (2012), culturally sustaining pedagogy seeks to perpetuate and foster linguistic, literate, and cultural pluralism as part of the democratic project of schooling. We conclude with strategies on how to successfully work with culturally diverse college students, promoting bilingual and biculturalism through cultural sustainment and code-switching.

Abstract
Purpose
The purpose of this paper is to provide an overview of the process of commissioning adult social care services in England. It reflects the literature on commissioning at the strategic level followed by a section on operational or micro-commissioning. The rest of the paper focusses on the emergence of ideas about outcomes-based commissioning (OBC) in the field of adult social care and ends with critical consideration of the effectiveness of OBC in adult social care as applied to support and care provided in extra care housing.
Design/methodology/approach
The review of strategic and operational commissioning in adult social care in England (and Scotland in brief) is based on both policy documents and a review of the literature, as are the sources addressing OBC in adult social care particularly in extra care housing settings.
Findings
The core of this paper focusses on the challenges to the implementation of OBC in adult social care in the context of provision for residents in extra care housing. Of central importance are the impact of the squeeze on funding, increasing costs as a result of demographic change and the introduction of a national living wage plus the focus on the needs of service users through the idea of person-centred care and resistance to change on the part of adult social care staff and workers in other relevant settings.
Originality/value
Addressing the implementation of OBC in adult social care in England in the context of extra care housing.

Abstract
Although there has been much psychological research about children's sibling relations, it has been a neglected area of study in sociology (exceptions are Brannen et al., 2000; Kosonen, 1996; Mauthner, 2002). This paper, based on empirical research on siblings in Scotland, explores the nature of the generational power structure within families from children's perspectives. Childhood is a relational concept which forms part of the generational order. Alanen explains this as “a complex set of social processes through which people become (are constructed as) ‘children’ while other people become (are constructed as) ‘adults’” (2001, pp. 20, 21). Generational processes shape the nature of child-parent relations (Mayall, 2002). Alanen states that:one position (such as the parental position) cannot exist without the other (child) position; also what parenting is – that is, action in the position of a parent – is dependent on its relation to the action “performed” in the child position, and a change in one part is tied to change in the other (Alanen, 2001, p. 19).In other words, child-parent relations are based on the understanding that childhood is relational with parenthood (see also Mayall, 2002). Alanen (2001) argues that the social construction of childhood and adulthood involves a process, including the agency of both children and adults, which she refers to as a set of “practices”:It is through such practices that the two generational categories of children and adults are recurrently produced and therefore they stand in relations of connection and interaction, of interdependence (Alanen, 2001, p. 21).These practices of generationing may be “childing” practices through which people are constructed as children or “adulting” practices through which a distinct adult position is produced. The ways in which children in the present study talked about the differences between their relationships with their parents and their siblings indicated that there are a range of generationing practices that take place within families. They referred to particular kinds of behaviour that were acceptable to engage in with other children (in this case with their siblings) but not with their parents. Overwhelmingly the key issue which children highlighted as distinct between their relations with parents and siblings was the differential nature of power in these relationships. Whilst it is not surprising that children perceive the distribution of power to be more unequal between children and parents than between siblings, the aim of this paper is to explore the nature of this power and how it is experienced from children's point of view. In particular the paper discusses the ways in which children perceive child-parent relations compared with their sibling relationships in relation to the giving and receiving of power within the home.

Abstract
Until the 2008 Crash, the prevailing economic orthodoxy, accepted across the broad political spectrum, was that inequality was a necessary condition for economic health. The evidence of the last four decades is that this trade-off theory – that you can have more equal or more efficient economies but not both – is incorrect. Not only do excessive concentrations of income and wealth bring social dislocation and breed public discontent with democratic institutions, but a number of studies have shown that inequality on today’s scale brings slower growth and greater economic turbulence. Although there is now a broad acceptance amongst global leaders that inequality poses significant risks for social cohesion and economic stability, there has been little or no action to match the high level verbal war against inequality. As a result, inequality has carried on rising within nations since 2008. In the United Kingdom, the gap between the top and bottom has continued to widen, in part because post-2010 governments have weakened the pro-equality role of the state. Tackling inequality is now one of the most pressing issues of the day – an economic as well as a social imperative – while reversing this four decade long trend will require a major restructuring of the pro-market economic models in place across most of the rich world.

Abstract
ABA has been described as a precise psychological approach to the study of behavior (Bailey & Burch, 2002), involving well-defined principles that can be used in the analysis and modification of individual behavior (Miltenberger, 1997). Special education, on the contrary, has been characterized as “a customized instructional program designed to meet the unique needs of the individual learner” (Gargiulo, 2009, p. 9). Certainly the two disciplines have much in common; indeed, ABA specifically addresses issues at the focal point of IDEA. For instance, ABA's stance on the right to effective behavioral treatment (Van Houten et al., 1988) is similar to special education regulations regarding the right to an appropriate public education and the right to be educated in the least restrictive environment.
