This paper aims to consider the nature and role of commitment in delivering value in customer–supplier relationships by developing and testing a model of relationship cooperativeness.

Data were collected using an extended version of the Industrial Marketing and Purchasing (IMP2) Group’s instrument. Pre-qualified managers largely self-completed the survey. Model associations were tested via regression and causal path analysis.

Various aspects of commitment play differing roles in relationship development. The role of commitment was less than expected; the exception is value-based commitment which is strongly associated with value creation, conflict management, trust and cooperation.

Findings provide explanations for some inconsistencies in previous findings including reported relationships between trust, cooperation and commitment. The composition of the commitment construct(s) strongly influences relationship processes.

There are various kinds of commitment to build and multiple pathways to levering this into more effective relationships. In addition, an important part of these findings is strong indications that illustrate what the nature of ineffective commitment-building paths is likely to be. This is extremely important for managers in guiding deployment of relationship management resources and developing relationship management practice.

The regulation of close business-to-business relationships remains an important issue, and the ways in which commitment can be appropriately extended are an important part of this.

This work focuses on the components of commitment in ways that previous work has not. The centrality of commitment in relationship value creation – beyond increased sales and revenue and predictability – is highlighted, and there is considerable extension to the understanding of the nature of this process.

There exists at present a gap in channel theory on the role of co‐operation and trust in the functioning of interfirm relationships. These variables have not featured as major factors in the explanations of how channels co‐ordinate their activities, survive and grow. This article introduces trust as an important determinant of channel behaviour, indicates the importance of trust in co‐operative behaviour and presents the results of an introductory study on trust in marketing channels.

Export grouping schemes are a commonly used vehicle for promoting international competitiveness, but their success rate is patchy. A perennial problem is the value of continuing the formal group structure itself. In this paper we examine the nature and role of export groups using the results from two in‐depth Australian case studies. The focus of analysis is on export groups as structuring devices rather than structures. They are viewed as action learning exercises in which knowledge and resource creating and self‐organizing processes are nurtured, these processes in turn shaping the evolution of interfirm relations and networks. Building on earlier work by Wilkinson and Young the dance metaphor is extended to depict and analyze export groups as dance parties. Dance themes are used to illustrate and dramatize issues arising in the design, development and evaluation of export grouping schemes and are related to the real experience of the two case studies examined.

Over the twentieth century, the relationships between the home and the school have been considered from a number of perspectives. These include social class and children’s education (David, 1993; Halsey et al., 1980; Utting, 1995); the language of the home and school (Bernstein, 1971); involving parents in their children’s learning (David, 1993; Mortimore & Mortimore, 1984; Sylva, 1987; Wolfendale, 1983); parents’ political participation in their children’s education (Ball, 1990; David, 1993; Deem, 1989; Golby, 1989; Macleod, 1989); home-school relations and minority ethnic families (Tomlinson, 1984); gender and home-school issues (David, 1993); family structure and children’s education (Cockett & Tripp, 1994; Utting, 1995); the treatment of family in the school curriculum (Cockett & Tripp, 1994; DfEE, 2000; OFSTED, 2002; Utting, 1995); the role of school in addressing students’ family problems (Cockett & Tripp, 1994; Rodgers & Pryor, 1998); and home-school contracts (Bastiani, 1991; David, 1993; Macbeth, 1989). The range of areas outlined above alone highlights the complexities of the issues surrounding home and school.

This paper aims to explore narratives of violence in the lives of young men and young women in Australia. Through partnering with young people to understand and make meaning of their stories, the authors highlight similarities and differences in gendered experiences of violence, and the implications of these for cross-disciplinary practice.

This article presents the synthesis of narrative data from two separate studies that worked with justice-involved young men and young women, who had both experienced and used violence. Study 1 used a thematic analysis of practitioner narratives and qualitative data from in-session narratives. Study 2 used a thematic analysis of interview data using grounded approach and peer review to promote trustworthiness and inter-rater reliability.

Insights on the experiences of young people who use violence are notably absent in most forms of violence discourse, practice and research. Findings demonstrate that understandings of youth violence are linked to identity, but also situated within contexts of trauma, place, gender, relationality and community. This conceptualisation of violence is particularly important to understandings of young female violence.

Through collaborative approaches of co-design and co-production, the paper outlines that a stronger understanding of the experiences of young men and young women (often an over-looked cohort) in the justice system can help improve the trauma-informed and gender responsiveness of interventions across practice settings. The authors highlight that exploring gendered differences in narratives of youth violence is necessary and seeking lived experiences of youth justice young people is instructive to academia, policy and practice.

Adolescence and emerging adulthood are key developmental stages with high risk for trauma exposure and the development of mental and substance-use disorders (SUDs). This study aims to compare the clinical profiles of adolescents (aged 12–17 years) and emerging adults (aged 18–25 years) presenting for treatment of posttraumatic stress disorder (PTSD) and SUD.

Data was collected from the baseline assessment of individuals (n = 55) taking part in a randomized controlled trial examining the efficacy of an integrated psychological therapy for co-occurring PTSD and SUDs (PTSD+SUD) in young people.

Both age groups demonstrated complex and severe clinical profiles, including high-frequency trauma exposure, and very poor mental health reflected on measures of PTSD, SUD, suicidality and domains of social, emotional, behavioral and family functioning. There were few differences in clinical characteristics between the two groups.

Similarity between the two groups suggests that the complex problems seen in emerging adults with PTSD + SUD are likely to have had their onset in adolescence or earlier and to have been present for several years by the time individuals present for treatment.

To the best of the authors’ knowledge, this is the first study to compare the demographic and clinical profiles of adolescents and emerging adults with PTSD + SUD. These findings yield important implications for practice and policy for this vulnerable group. Evidence-based prevention and early intervention approaches and access to care are critical. Alongside trauma-focused treatment, there is a critical need for integrated, trauma-informed approaches specifically tailored to young people with PTSD + SUD.

This article is based on a study that was commissioned by the Youth Justice Board for England and Wales. We report on the learning profiles and education needs of a cohort of young offenders who were recruited for the study. The research was a national cross‐sectional survey of 301 young offenders who were resident in custodial settings or attending youth offending teams in the community. The young people were assessed using the WASI and the WORD measures to obtain psychometric information (IQ scores and reading/reading comprehension ages). One in five (20%) young people met the ICD‐10 criteria for mental retardation (IQ<70), while problems with reading (52%) and reading comprehension (61%) were common. Verbal IQ scores were found to be significantly lower than performance IQ scores, particularly in male offenders. It is clear from these results that a large proportion of juvenile offenders have a learning disability, as characterised by an IQ<70 and significantly low reading and reading comprehension ages. The underlying aetiology of this association is less clear and may be a consequence of both an increased prevalence of neurocognitive deficits and the impact of poor schooling. There is some evidence that developmental pathways may be different for boys compared with girls.

Interest in psychological resilience has grown rapidly in the last couple of decades (Britt, Sinclair, & McFadden, 2016; King & Rothstein, 2010; Youssef & Luthans, 2007). Psychological resilience occurs when a person can “recover, re-bound, bounce-back, adjust or even thrive” in the face of adversity (Garcia-Dia, DiNapoli, Garcia-Ona, Jakubowski, & O’flaherty, 2013, p. 264). As such, resilience can be conceptualized as a state-like and malleable construct that can be enhanced in response to stressful events (Kossek & Perrigino, 2016). It incorporates a dynamic process by which individuals use protective factors (internal and external) to positively adapt to stress over time (Luthar, Cicchetti, & Becker, 2000; Rutter, 1987). Building on the dual-pathway model of resilience, we integrate adaptive and proactive coping to the resilience development process and add a heretofore unexamined perspective to the ways in which resilience changes over time. We propose that resilience development trajectories differ depending on the type of adversity or stress experienced in combination with the use of adaptive and proactive coping. We outline the need for future longitudinal studies to examine these relationships and the implications for developing resilience interventions in the workplace.

This paper aims to develop a numerical, micromechanical model to predict the evolution of autogenous shrinkage of hydrating cement paste at early age (up to 7 days). Autogeneous shrinkage can be important in high-performance concrete characterized by low water to cement (w/c) ratios. The occurrence of this phenomenon during the first few days of hardening may result in early-age cracking in concrete structures. A good prediction of autogeneous shrinkage is necessary to achieve better understanding of the mechanisms and the deployment of effective measures to prevent early-age cracking.

Three-dimensional digital microstructures from the hydration modelling platform μic of cement paste were used to simulate macroscopic autogenous shrinkage based on the mechanism of capillary tension. Elastic and creep properties of the digital microstructures were calculated by means of finite element (FE) method homogenization. Autogenous shrinkage was then estimated as the average hydrostatic strain resulting from the capillary stress that was globally applied on the simulated digital microstructures. For this estimation, two approaches of homogenization technique, i.e. analytical poro-elasticity and numerical creep-superposition were used.

The comparisons of between the simulated and experimentally measured deformations indicate that the creep-superposition approach is more reasonable to estimate shrinkage at different water to cement ratios. It was found that better estimations could be obtained at low degrees of hydration, by assuming a loosely packed calcium silicate hydrates (C-S-H) growing in the microstructures. The simulation results show how numerical models can be used to upscale from microscopic characteristics of phases to macroscopic composite properties such as elasticity, creep and shrinkage.

While the good predictions of some cement paste properties from the microstructure at early age were obtained, the current models have several limitations that are needed to overcome in the future. Firstly, the limitation of pore-structure representation is not only from lack understanding of C-S-H structure but also from the computational complexity. Secondly, the models do not consider early-age expansion that usually happens in practice and appears to be superimposed on an underlying shrinkage as observed in experiments. Thirdly, the simplified assumptions for mechanical simulation do not accurately reflect the solid–liquid interactions in the real partially saturated system, for example, the globally applying capillary stress on the boundary of the microstructure to find the effective deformation, neglecting water flow and the pore pressure. Last but not least, the models, due to the computational complexities, use many simplifications such as FE approximation, mechanical phase properties and creep statistical data.

This study holistically tackles the phenomenon of autogeneous shrinkage through microstructural modelling. In a first such attempt, the authors have used the same microstructural model to simulate the microstructural development, elastic properties, creep and autogeneous shrinkage. The task of putting these models together was not simple. The authors have successfully handled several problems at each step in an elegant manner. For example, although several earlier studies have pointed out that discrete models are unable to capture the late setting times of cements due to mesh effects, this study offers the most effective solution yet on the problem. It is also the first time that creep and shrinkage have been modelled on a young evolving microstructure that is subjected to a time variable load.
