Insect pollination underpins apple production but the extent to which different pollinator guilds supply this service, particularly across different apple varieties, is unknown. Such information is essential if appropriate orchard management practices are to be targeted and proportional to the potential benefits pollinator species may provide. Here we use a novel combination of pollinator effectiveness assays (floral visit effectiveness), orchard field surveys (flower visitation rate) and pollinator dependence manipulations (pollinator exclusion experiments) to quantify the supply of pollination services provided by four different pollinator guilds to the production of four commercial varieties of apple. We show that not all pollinators are equally effective at pollinating apples, with hoverflies being less effective than solitary bees and bumblebees, and the relative abundance of different pollinator guilds visiting apple flowers of different varieties varies significantly. Based on this, the taxa specific economic benefits to UK apple production have been established. The contribution of insect pollinators to the economic output in all varieties was estimated to be £92.1M across the UK, with contributions varying widely across taxa: solitary bees (£51.4M), honeybees (£21.4M), bumblebees (£18.6M) and hoverflies (£0.7M). This research highlights the differences in the economic benefits of four insect pollinator guilds to four major apple varieties in the UK. This information is essential to underpin appropriate investment in pollination services management and provides a model that can be used in other entomolophilous crops to improve our understanding of crop pollination ecology.

The use of simulation games as a pedagogic method is well established though its effective use is context-driven. This study adds to the increasing growing body of empirical evidence of the effectiveness of simulation games but more importantly emphasises why by explaining the instructional design implemented reflecting best practices. This multimethod study finds evidence that student learning was enhanced through the use of simulation games, reflected in the two key themes; simulation games as a catalyst for learning and simulation games as a vehicle for learning. In so doing the research provides one of the few empirically based studies that support simulation games in enhancing learning and, more importantly, contextualizes the enhancement in terms of the instructional design of the curriculum. This research should prove valuable for those with an academic interest in the use of simulation games and management educators who use, or are considering its use. Further, the findings contribute to the academic debate concerning the effective implementation of simulation game-based training in business and management education.

Although business simulations are widely used in management education, there is no consensus about how to optimise their application. Our research explores the use of business simulations as a dimension of a blended learning pedagogic approach for undergraduate business education. Accepting that few best-practice prescriptive models for the design and implementation of simulations in this context have been presented, and that there is little empirical evidence for the claims made by proponents of such models, we address the lacuna by considering business student perspectives on the use of simulations. We then intersect available data with espoused positive outcomes made by the authors of a prescriptive model. We find the model to be essentially robust and offer evidence to support this position. In so doing we provide one of the few empirically based studies to support claims made by proponents of simulations in business education. The research should prove valuable for those with an academic interest in the use of simulations, either as a blended learning dimension or as a stand-alone business education activity. Further, the findings contribute to the academic debate surrounding the use and efficacy of simulation-based training [SBT] within business and management education.

Social capital has emerged as a concept of great interest and potential to help understand and explain how social structures and networks impact political, social and business practices at the collective and individual levels. The basic premise is: investment in social relations will yield expected returns. Extant research has largely focused on the West; our knowledge of how social capital plays out in the Middle East is limited. We marry social capital with ‘wasta’, the strong family and tribal based connections secured in networks in the Arab world, and investigate HR managers’ perceptions of wasta in employment selection in Jordan. Often use of wasta in employment selection is related to favouritism and nepotism and the many negative outcomes of not adhering to merit-based selection. Through in-depth interview data we reveal a more nuanced and multifaceted view of wasta in employment selection. When examined through the social capital lens six distinct themes emerge: (i) wasta as an enabler to get jobs, (ii) wasta as social ties/ solidarity, (iii) wasta as a method to transfer/ attain information, (iv) wasta as a guide in decision-making, (v) wasta as an exchange, and (vi) wasta as pressure. Our findings confirm that at times wasta grants individuals unfair access to employment that is beyond their qualifications, skills, knowledge and/ or abilities. However, organisational context is relevant. In banking, not all roles are open to wasta. Where the possible negative impact on the organisation poses too great a risk HR managers feel able to resist even strong wasta. Context also emerges as being of key importance with regards to the background and business model of an organisation. Family businesses tend to operate wasta more frequently and extensively using tribal connections, religious networks and geographical area based networks as a key source in hiring. Despite globalisation and international nature of banking, wasta and tribalism feature strongly in daily business conduct in Jordan. Our paper illuminates the positive effects of wasta, e.g.as a method to transfer information, together with discussion on the dangers of ‘cloning’, a (lack of diversity), and the dangers of an incompetent workforce .

A number of research studies have reported abnormal plasma fatty acid profiles in children with ADHD along with some benefit of n−3 to symptoms of ADHD. However, it is currently unclear whether (lower) long chain-polyunsaturated fatty acids (LC-PUFAs) are related to ADHD pathology or to associated behaviours. The aim of this study was to test whether (1) ADHD children have abnormal plasma LC-PUFA levels and (2) ADHD symptoms and associated behaviours are correlated with LC-PUFA levels. Seventy-two, male children with (n=29) and without a clinical diagnosis of ADHD (n=43) were compared in their plasma levels of LC-PUFA. Plasma DHA was higher in the control group prior to statistical correction. Callous–unemotional (CU) traits were found to be significantly negatively related to both eicosapentaenoic acid (EPA), and total omega-3 in the ADHD group. The findings unveil for the first time that CU and anti-social traits in ADHD are associated with lower omega-3 levels.

We evaluate whether society can adequately be conceptualized as a component of social-ecological systems, given social theory and the current outputs of systems-based research. A mounting critique from the social sciences posits that resilience theory has undertheorized social entities with the concept of social-ecological systems. We trace the way that use of the term has evolved, relating to social science theory. Scientometic and network analysis provide a wide range of empirical data about the origin, growth, and use of this term in academic literature. A content analysis of papers in Ecology and Society demonstrates a marked emphasis in research on institutions, economic incentives, land use, population, social networks, and social learning. These findings are supported by a review of systems science in 18 coastal assessments. This reveals that a systems-based conceptualization tends to limit the kinds of social science research favoring quantitative couplings of social and ecological components and downplaying interpretive traditions of social research. However, the concept of social-ecological systems remains relevant because of the central insights concerning the dynamic coupling between humans and the environment, and its salient critique about the need for multidisciplinary approaches to solve real world problems, drawing on heuristic devices. The findings of this study should lead to more circumspection about whether a systems approach warrants such claims to comprehensiveness. Further methodological advances are required for interdisciplinarity. Yet there is evidence that systems approaches remain highly productive and useful for considering certain social components such as land use and hybrid ecological networks. We clarify advantages and restrictions of utilizing such a concept, and propose a reformulation that supports engagement with wider traditions of research in the social sciences.

Communicating science can be challenging at any educational level. We used informal and experiential learning to engage groups of potential University applicants in one project that involved staging a play in one of the teaching laboratories at the University of Worcester whilst a second project designed a play in house and took this to schools. In the first project the plot centred on stem cell research. School pupils and students from FE Colleges were offered complementary sessions including a lecture exploring the science behind stem cell research, a discussion on ethical aspects involved and a practical using university facilities. We ascertained attitudes to Higher Education in the students participating before and after the event. We found an enhanced view of the science and a highly significant change in attitude to attending University for students taking vocational subjects at FE level. The second project was aimed at exploring attitudes to ethics and animal welfare among a cohort of 15 – 18 year olds. Students engaged with the issues in the drama to a high degree. Our conclusions are that drama is an excellent way to inform potential students about higher education and HE level science in particular. Additionally we demonstrated the importance of events taking place at HE institutions in order to maximise change in attitudes to HE.

Partnership is a dominant theme in education policy and practice in England and in other western countries but remains relatively under-researched, especially with respect to what sustains a partnership. This article draws on a study of partnership working in the field of post-16 learning that revealed the role of dimensions of social capital in supporting and sustaining the case study partnership. The research adopted a grounded approach and used multiple methods of data gathering including observations of partnership meetings, semi-structured interviews and documentary research. The findings reported here focus on aspects of partnership working and facets of social capital that support and sustain partnership, including multiple layers of collaboration, networks and networking, high levels of trust and shared norms and values amongst key participants. The analysis suggests that the contested concept of social capital provides a useful theoretical frame for understanding the basis of sustainability in education partnerships.

Fungal and oomycete pathogens are the causal agents of many important plant diseases. They affect crops that are staple foods for humans and livestock and are responsible for significant economic losses every year. This in turn generates a global social impact. Although fungi and oomycetes evolved separately, they share similar strategies and weaponry to attack plants. Here we review the challenges to global food security posed by these pathogens, current technologies used for detection and diagnostics, the latest understanding of pathogens' strategies to colonize plants, and current and future control measures. Genomic sequences of several important fungal and oomycete pathogens, as well as many crop plants, are now available and are helping to increase understanding of host–pathogen interactions. Recent developments in this field are discussed.
