Using recent US regional data associated with food system operations, this study aims at building optimization and econometric models to incorporate varying influential factors on food hub location decisions and generate effective facility location solutions.

Mathematical optimization and econometric models have been commonly used to identify hub location decisions, and each is associated with specific strengths to handle uncertainty. This paper develops an optimization model and a hurdle model of the US fresh produce sector to compare the hub location solutions between these two modeling approaches.

Econometric modeling and mathematical optimization are complementary approaches. While there is a divergence between the results of the optimization model and the econometric model, the optimization solution is largely confirmed by the econometric solution. A combination of the results of the two models might lead to improved decision-making.

This study suggests a future direction in which model development can move forward, for example, to explore and expose how to make the existing modeling techniques easier to use and more accessible to decision-makers.

The models and results provide information that is currently limited and is useful to help inform sustainable decisions of various stakeholders interested in the development of regional food systems, regional infrastructure investment and operational strategies for food hubs.

This study sheds light on how the application of complementary modeling approaches improves the effectiveness of facility location solutions. This study offers new perspectives on elaborating key features to encompass facility location issues by applying interdisciplinary approaches.

The purpose of this paper is to explore the experiences of both staff and patients in a medium-secure mental health unit of the self-harm and/or suicidal behaviour of others. Suicide and self-harm is highly prevalent in forensic settings and evidence suggests that experiencing other people’s self-harm and suicidal behaviour can lead to negative outcomes, both for staff and patients. This is particularly important in hospitals where patients are highly dependent on staff for support.

Semi-structured interviews were conducted with five staff members and six patients in a medium-secure male mental health unit in the North of England. Data were analysed following interpretative phenomenological analysis guidelines.

Three dominant themes were identified during analysis: the impact of suicide and self-harm; the role of others; and the importance of understanding and experience. Various impacts were discussed including desensitization, negative emotions and the desire to help. Other people played an important role in protecting against negative impacts, with shared experiences and peer support reported as the biggest benefits. Experiences of self-harm and suicide were found to increase understanding resulting in more positive attitudes. Additionally, the importance of training and education was highlighted.

This paper provides an insight into the experiences of staff and patients in medium-secure male mental health unit, which has benefits to practitioners when considering support mechanisms.

The paper examines the factors that influence the production of cash flows in a sample of Italian farm accountancy data network (FADN) farms to generate information useful for calibrating policies to support farmers' investments.

An econometric analysis on the sample estimates the influence of structural, economic, commercial and financial variables on CAFFE, i.e. the cash flow that includes the payments to the farmer's resources and the free cash flow on equity (FCFE). The econometric problem of endogeneity is treated by adopting the Hausman test to choose between fixed and random effects models. The results for Italian agriculture and its types of farming (TFs) are examined based on the FCFE/capital depreciation ratio, where FCFE subtracts from CAFFE the opportunity cost payments to the farmer's resources. This ratio identifies TFs with problems of sustainability of the production system.

The results show that increasing the productive dimension, in particular the endowment of farmland and working capital, is still essential to stimulate the production of cash flows of Italian agriculture. Without this growth, increasing the depreciable capital base is ineffective. FCFE does not compensate for depreciation in several TFs, which in various cases could also improve by improving economic efficiency and commercial position.

Assessing the factors that most influence cash flows can help to better calibrate rural development measures to the territories and farming types that most need public support. Our analysis procedure can be applied to all production systems equipped with farm accounting networks; however, the criteria for rewarding farmer resources and calculating the replacement value of agricultural capital need to be better discussed.

The specification of rural development policies rarely takes into account the financial sustainability conditions of farms, as well as the factors that determine them, in defining the support parameters and the selection criteria for funding. Our approach, based on the analysis of FADN data, considers these aspects and provides ideas for better calibrating public support for investments among agricultural territories, sectors and types of farms.

The purpose of the present study is to investigate mediating mechanisms in the relationship between the training and development climate at higher education institutions and administrative employees' productivity. Organizational identification theory and the job demands-resources model are used to investigate supervisor support, employees' motivation to learn and employee engagement as mediators.

Survey research was used to collect data from 289 administrative staff members employed at five higher education institutions in Trinidad and Tobago.

The findings supported the hypothesized mediating role of supervisor support, employees' motivation to learn and employee engagement in the relationship between organizations' training and development climate and employee productivity.

Productivity is a major problem in Trinidad and Tobago. In Trinidad and Tobago's higher education sector, productivity deficiencies are particularly problematic because of the gradual reduction in government subsidies. Therefore, higher education institutions must improve productivity, particularly administrative employees' productivity, in order to compete with local and international tertiary education institutions. This study contributes to Trinidad and Tobago's society by showing the importance of both a positive training and development climate and supervisor support to influence administrative employees' affective states and productivity in tertiary education institutions.

This study adds to existing research on training and development and employee productivity by introducing novel and theoretically sound mediators to clarify how the relationship between a higher education institution's training and development climate and its administrative employees' productivity unfolds.

The purpose of this paper is to explore the association of cybercrime, autistic spectrum conditions and international law enforcement, the past decade having seen a significant growth in reported cybercrimes involving autistic individuals.

Interest in the profile of autism and cybercrime and the pathways whereby such offences are committed is shared by key law-enforcement agencies worldwide. This was explored by literature review and survey.

The authors identified a presence of persons with Autism Spectrum Disorders but no empirical evidence to suggest a prevalence or an over representation of autistic individuals committing cybercrime offences. At present profiling, pathways, and recording is under developed.

Paucity of literature on cybercrime and autism. Awareness of autism within law-enforcement agencies and the absence of key diagnostic and other data from the cross-section of agencies surveyed.

Improve detection, diversion, profiling, risk and pathways into cybercrime.

Better prediction of risk of cybercrime and improved responses.

Original paper believed to be the first to look at cybercrime and ASD in the context of international law enforcement.

In South Africa, the majority of the population struggles to access care and support for mental health challenges. Drawing on challenges faced by asylum seekers and refugees in the urban margins of Johannesburg, this paper aims to explore the relationship between migration and mental health through a lens of heightened vulnerability, precarious urban spaces and unmet basic needs.

Remote interviews were conducted with respondents working in the mental health-care sector (public and private) and with migrant communities in Johannesburg. Respondents were identified via purposive sampling and interviews were conducted in English. Key findings were identified using thematic analysis.

Effective responses to asylum seekers and refugees facing mental health challenges are based on an understanding of context, of crisis and of the need to meet basic needs such as paying rent, finding employment and providing for families. These “daily stressors” not only compound “extreme traumatisation” but are a form of trauma in and of itself.

This paper shows how alternative responses determined by an understanding of context, of crisis and of the need to meet basic needs provide critical and potentially far-reaching interventions. Locating trauma in the unmet needs, precarious urban spaces and marginalisation opens up space to further question the ways that migration and mental health shape and reshape one another.

This paper reports a social work student’s experience of a mental health rehabilitation placement. The term “dual diagnosis” in this context includes people who experience both a mental health diagnosis and a substance use disorder. The purpose of this paper is to highlight the student experience as the author learnt about some of the challenges that people with dual diagnoses face during the recovery process.

The author kept a journal during the placement. Critical reflection was used to interrogate the journal entries for key themes and events that contributed to the author’s learning about social work practice and dual diagnosis.

This study found that social workers are in a fortunate position to work in this multi-disciplinary setting and contribute the social work perspective to care for people with dual diagnosis. However, there are still some gaps in achieving optimal care.

Suggestions for further practice development include a more integrated approach between services, further training for clinicians and a focus on a community-based setting as opposed to an institutionalised one.

According to the author, the student experience is important because students see situations and settings with fresh eyes that can highlight things that experienced practitioners take for granted.

In the UK, food poverty has increased in the last 15 years and the food aid supply chain that has emerged to tackle it is now roughly 10 years old. In this time, we have seen the food aid supply chain grow at a rate that has astounded many. Recently that growth has been aided by a grant of £20m from a large supermarket chain. It appears institutionalisation is just around the corner, if not already here. It also appears that there is far greater emphasis on dealing with the symptoms as opposed to solving the root causes of the problem. As an opinion piece, this paper reflects on some of the prevalent issues, and suggests some ways forward.

The scientific literature evidences that the quality of care must be improved. However, little research has focused on investigating how health care managers – who are responsible for the implementation of quality interventions – define good and poor quality. The purpose of this paper is to develop an empirically informed taxonomy of quality care as perceived by US managers – named the Integrative Quality Care Assessment Tool (INQUAT) – that is grounded in Donabedian’s structure, process and outcome model.

A revised version of the critical incident technique was used to collect 135 written narratives of good and poor quality care from 74 health care managers in the USA. The episodes were thematically analyzed.

In total, 804 units were coded under the 135 written narratives of care. They were grouped under structure (9 percent, n=69), including organizational, staff and facility resources; process (52 percent, n=419), entailing communication, professional diligence, timeliness, errors, and continuity of care; outcomes (32 percent, n=257), embedding process- and short-term outcomes; and context (7 percent, n=59), involving clinical and patient factors. Process-related categories tended to be described in relation to good quality (65 percent), while structure-related categories tended to be associated with poor quality (67 percent). Furthermore, the data suggested that managers did not consider their actions as important factors influencing quality, but rather tended to attribute the responsibility for quality care to front-line practitioners.

The INQUAT provides a theoretically grounded, evidence-based framework to guide health care managers in the assessment of all the components involved with the quality of care within their institutions.
