Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Practical implications

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.

Social implications

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.

Originality/value

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.

Abstract

Purpose

Disparities in transplant rates across social categories provide limited information about gatekeeping processes in access to kidney transplantation. We hypothesized that early opportunities for discussion of kidney transplantation potentially generate social capital that serves as a resource for patients as they navigate the transplantation pathway.

Methodology

A national sample of first-year dialysis patients was surveyed and asked if kidney transplantation had been discussed with them before and after starting dialysis treatment. Associations between reported discussion and patient-specific clinical and nonclinical (sociodemographic) indicators of attributed utility for transplantation were investigated, and the association of reported transplant discussion with subsequent transplant waitlisting was analyzed.

Findings

Time to placement on the kidney transplant waiting list was significantly shorter for patients who reported that transplantation had been discussed with them before, as well as after, starting dialysis. Likelihood of reported discussion varied by patient age, employment and insurance status, cardiovascular comorbidity burden, and perceived health status; in addition, women were less likely to report early discussion.

Research limitations

It would be valuable to know more about the nature of the transplant discussions recalled by patients to better understand how social capital may be fostered through these discussions.

Practical implications

Indicators of attributed utility for successful transplantation were associated with transplant discussion both before and after starting dialysis, potentially contributing to observed disparities in access to kidney transplantation.

Social implications

Predialysis nephrology care and patient participation in discussion of kidney transplantation may foster social capital that facilitates navigating the transplantation pathway.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Research limitations/implications

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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

Findings

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.

Social implications

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Research limitations/implications

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.

Practical implications

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

Social implications

Better prediction of risk of cybercrime and improved responses.

Originality/value

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

Abstract

Depression is a prevalent, debilitating condition that will replace cancer as the second leading cause of morbidity within the next decade and, according to the Global Burden of Disease Study, ranks number one in disability-adjusted life years for females 5 years and older worldwide (Blehar & Oren, 1997; Murray & Lopez, 1996). Depression in the workplace has been linked to increased absenteeism and productivity loss, is equal to the costs of diabetes and hypertension, and these costs are almost equal to the direct costs of depression treatment (Kessler et al., 1999; Marlowe, 2002; Druss, Rosenheck, & Sledge, 2000; Elinson, Houck, Marcus, & Pincus, 2004). A national study of individuals 15–54 years documented a lifetime prevalence of 17.1% and found that depression was more common in females, young adults, and those with less education (Blazer, Kessler, McGonagle, & Swartz, 1994; Kessler, McGonagle, Swartz, Blazer, & Nelson, 1993; Substance Abuse and Mental Health Services Administration, 2000; Kessler et al., 1994a, 1994b; Bebbington et al., 2003).

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

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.
