Internet-based applications in the agri-food supply chain:a survey on the Greek canning sector

In the agri-food industry, Internet-based applications changed the way companies conduct business mainly by facilitating activities that were already taking place, rather by giving birth to virtual networks creation. Due to the specific characteristics of the sector, Internet's huge potential has not been fully exploited yet, still remaining a new communication tool. This paper aims at giving empirical insights regarding the use of Internet-based applications in the agri-food supply chain, by focusing on the Greek fruit canning sector. In particular, the paper identifies companies' perceptions regarding perceived benefits, constrained factors and motivation factors towards the use of Internet-based applications. Results indicate that companies recognise benefits arising from the use of Internet, however they still use traditional ways when communicating with their partners. Regarding transportation issues, while companies' overall satisfaction is rather moderate and differs significantly from the importance placed on a number of criteria, companies are still sceptical in using Electronic Transportation Marketplace

Exploring the impact of e-business adoption on logistics processes:empirical evidence from the food industry

The objectives of the research were to identify factors that influence e-business adoption and its impact on logistics processes in the Greek food industry. Drawing on existing research, a conceptual framework and propositions were developed and six in depth case studies were carried out. In the framework, three major categories of influencing factors were distinguished: intra-enterprise, sector and supply chain factors. Findings suggest that e-business adoption is more affected by supply chain and sector factors, rather than intra-enterprise factors. Regarding the impact of e-business on logistics process, it seems that it is affected by the frequency of its use and it is greater in processes occurring at the company-customer interface. Finally, e-business impact is more related to the dimensions of time and quality, rather than cost improvements

A conceptual framework for supply chain collaboration:empirical evidence from the agri-food industry

Purpose - The purpose of this paper is to analyse the concept of supply chain collaboration and to provide an overall framework that can be used as a conceptual landmark for further empirical research. In addition, the concept is explored in the context of agri-food industry and particularities are identified. Finally, the paper submits empirical evidence from an exploratory case study in the agri-food industry, at the grower-processor interface, and information regarding the way the concept is actually applied in small medium-sized enterprises (SMEs) is presented. Design/methodology/approach - The paper employed case study research by conducting in-depth interviews in the two companies. Findings - Supply chain collaboration concept is of significant importance for the agri-food industry however, some constraints arise due to the nature of industry's products, and the specific structure of the sector. Subsequently, collaboration in the supply chain is often limited to operational issues and to logistics-related activities. Research limitations/implications - Research is limited to a single case study and further qualitative testing of the conceptual model is needed in order to adjust the model before large scale testing. Practical implications - Case study findings may be transferable to other similar dual relationships at the grower-processor interface. Weaker parts in asymmetric relationships have opportunities to improve their position, altering the dependence balance, by achieving product/process excellence. Originality/value - The paper provides evidence regarding the applicability of the supply chain collaboration concept in the agri-food industry. It takes into consideration not relationships between big multinational companies, but SMEs

Prisoners in Greek prisons: Correlation of demographic and psychosocial data with committed crimes

Previous literature shows an association between several psychosocial factors or life events in general and delinquency. Factors such as gender, cannabis and drugs use are firmly connected to delinquency. Similarly, interpersonal violent behavior appears to be more frequent in people with lower socioeconomic status and people with lower education. The association of these factors with the violent or non-violent crimes, especially in Greek research literature, is very limited. The present study is an attempt to examine in a Greek prison population the correlation of demographic and psychosocial factors with violent and non-violent crime. The prison population sample comprised of 308 males from a total of 1300 prisoners, aged between 18 and 77 years old. The survey was conducted from January 2012 until August 2013 in Korydallos and Domokos prisons. In our prison population sample most of the crimes were non-violent. The prisoners were urban dwellers, of young age, were not married and were in short-term relationships on average. They had completed their military obligations, were not live alone, and have been working in the last six months before being imprisoned, in manual labor. They had low-grade education and poor school achievements, had been brawling with classmates and had history of antisocial behavior (liked to "put fire" and abuse animals). They report good relationships with their parents; however, they had experienced violence in parental relationships and some kind of violence, mainly by the father and secondarily by the mother. They have not been involved in gangs necessarily and have a history from a young age, of alcohol, cannabis and drugs use. Cannabis use history was reported by 208 prisoners (67.5%) and 133 (63.9%) of them started using at the age of 10-15 years old. A total of 179 prisoners (58.5%) reported a history of drug use, about half of them (50.3%) reported being addicted to a combination of drugs. For 40.8% (n=73) drug use was initiated in the age of 10-15 years old, while the largest percentage (46.4%) of prisoners mentioned as starting age 16-20 years old. Although the above features underline the great differences between prison population and the general population, there are no significant associations of these factors with violent or non-violent crime. However, the prisoners with drug use history were 65% less likely to have been sentenced for violent crime. Also, the prisoners exempted from their military duties, were 49% less likely to have committed violent crime

Association of Schizoid and Schizotypal Personality disorder with violent crimes and homicides in Greek prisons

Background: Personality disorders (PDs) have been associated with both violent crimes and homicides in many studies. The proportion of PDs among prisoners reaches up to 80%. For male prisoners, the most common PD in the literature is antisocial PD. The aim of this study was to investigate the association between PDs and violent crimes/homicides of male prisoners in Greece. Methods: A sample of 308 subjects was randomly selected from a population of 1300 male prisoners incarcerated in two Greek prisons, one urban and one rural. The presence of PDs was assessed using the Mini International Neuropsychiatric Interview (MINI) and the Personality Diagnostic Questionnaire-4 (PDQ-4). Using logistic regression models PD types and PD "Clusters" (independent variables) were associated with "violent/non-violent crimes" and "homicides/non homicides" (dependent variables). Results: "Cluster A" PDs (Paranoid, Schizoid, and Schizotypal) were diagnosed in 16.2%, "Cluster B" (Antisocial, Borderline, Histrionic, Narcissistic) in 66.9% and "Cluster C" (Obsessive-Compulsive, Dependent, Avoidant) in 2.9% of the studied population. Violent crimes and homicides were found significantly associated with "Cluster A" PDs (p = 0.022, p = 0.020). The odds ratio of committing violent crimes was 2.86 times higher for patients with "Cluster A" PDs than the ones without PDs. In addition, the odds ratio of committing homicides was 4.25 times higher for patients with "Cluster A" PDs. In separate analyses, the commitment of violent crimes as well as homicides, was significantly associated with Schizoid (p = 0.043, p = 0.020) and Schizotypal PD (p = 0.017, p = 0.030). Conclusions: The majority of prisoners was found to suffer from a PD, mainly the Antisocial "Cluster B", but the commitment of violent crimes and homicides was significantly associated only with "Cluster A" PDs and specifically with Schizoid and Schizotypal PD. © 2018 The Author(s)
