The purpose of this paper is to study the traffic‐police enforcement process and develop models to improve enforcement effectiveness given substantial budgetary and resource constraints.

The formulation crosses the concepts of lean manufacturing and linear programming. Traffic police officers, automated machines and the back‐office are modeled in a similar manner to that of a manufacturing plant, working together to achieve ticket production as a function of quantity and quality, based on a preferential ranking of offence types.

Using data from the Israeli traffic police over a six‐year period, the case study shows that given available resources, it is possible to retain ticket quantity whilst significantly improving ticket quality as defined in the road safety literature. The case study shows a 24 per cent increase in quality ticket processing whilst taking into account the court summons constraint and maintaining throughput levels. This draws from changes in the method of ticket‐production, production of warnings rather than tickets in certain cases and the application of new technologies.

The results are limited by the current lack of data and require a cost‐benefit analysis in order to further develop certain parameters.

The application of the approach improves the holistic planning of traffic enforcement activities as well as providing specific details, such as the number and distribution of ticket production.

This research merges three disciplines; operations research, road safety and operations management, generating a methodology for the planning and control of traffic police ticket issuance, which has not been analyzed in the literature to date.

I suggest that the search for Adam Smith’s theodicy is likely to be in vain. The paper begins with a brief history of approaches to evil, emphasizing the context in which they arose, and the questions authors were addressing. Approaches most relevant to Adam Smith include those of Augustine and Calvin, and the early modern theodicies of Leibniz, Samuel Clarke and William King, as well as the attacks on them by Bayle and Voltaire. Scottish Enlightenment writers were not terribly interested in theodicy, though Hutcheson and Kames did devote space to their versions of problems of evil. David Hume’s Dialogues on Natural Religion are often taken to be classic statement of the problem of theodicy and argument against religious belief, but his concern was to demolish rationalistic theodicies rather than religious belief or practice. The paper then turns to Smith’s writings, considering similarities and differences to these approaches to evil. Smith emphasizes the wisdom and beneficence of God, and that evils we observe are part of a larger providential plan. He makes no attempt to justify the God in the face of evil, and in this respect Smith shares more with Augustine and Calvin than he does with the early modern theodicists. Smith’s approach to evil is simple and ameliorative. Smith’s approach contrasts with early nineteenth century English political economists, from Malthus onwards, for whom theodicy was important. Whatever view we take of the theodicists project of justifying an all-powerful and good God in the face of evil may, we still struggle to make sense of economic suffering and evil.

Risk attitude is an elementary attribute of entrepreneurial behaviour. Determinants of risk-taking propensity have been widely investigated in the group of entrepreneurs and non-entrepreneurs so far. There is a lack of evidence on determinants of risk-taking propensity in the farming business, which is considered as risky business because of the ongoing climate change and epidemic outbreaks. Alternatively, the risk of lower European Union budget raised the question, how to implement publicly supported financial instruments for micro and small farmers which have lower credit rating. The purpose of this study is to find socio-demographic determinants of the risk-taking propensity of the Czech micro farms, controlling for the type of farming.

The survey of 747 micro farmers was processed through ordinal logistic regression. The study is based on the subjective self-assessment of the risk-taking behaviour which is frequently used to measure risk-taking attitude. The results are representative from the type of farming point of view.

The model provided clear evidence that age, household size, living with the partner/wife/husband and level of education have a significant relationship with risk-taking propensity. The most risk-tolerant farmers are young with less formal education and living in small households. The risk-taking propensity varies by the type of farming. Specialized crop farms have significantly higher risk-taking propensity than farms with a substantial share of livestock production. Alternatively, gender, feeling about household income and religion are not significantly related to the risk-taking propensity of the Czech micro farms.

The main limitation of the study is the number of explanatory variables and the use of self-assessment of risk-taking attitude. The risk attitude can be explained by other variables which require in-depth qualitative research, such as past risk experience, the structure of decision problems, market orientation and operation under subsistence conditions.

The significant determinants of risk-taking attitude of micro farmers are important for banks, the Czech Support and Guarantee Fund for Farmers and Forestry and for policymakers who design the rules for post-2020 common agricultural policy. The study is original and valuable for the Central and Eastern European countries’ implementation of financial instruments as new rules for investment support are being prepared and research on the risk-taking attitude of the most vulnerable segment of farmers has not been conducted.

The originality of this study is from the perspective of agricultural sector as well as from the micro farms point of view. The results have commercial and political implications. Younger farmers, singles and lower-educated farmers have significantly higher risk-taking propensity and can be potentially risky clients for banks. Such farmers represent the financial gap in the credit market, and their viable development projects could be subject for implementation of financial instruments co-financed by the European Agricultural Fund for Rural Development in the forthcoming programming period past 2020.

The purpose of this paper is to review the nutritional and phytochemical value of Moringa oleifera L., along with health benefits. Moringa oleifera, a highly valued plant grown throughout the world and all parts of tree used in different food formulations, possess industrial and therapeutic uses. This plant is gaining popularity because of its nutrient-rich root, leaves, flowers and fruits, having immense traditional medicinal uses and proved pharmacological properties.

Major well-known bibliometric information sources such as Web of Science, Scopus, Mendeley and Google Scholar were searched with keywords such as nutrition value of Moringa oleifera, bioactive compounds, health benefits, processing and safety were chosen to obtain a database of 1,386 papers. A final database of 70 scientific sources was made after sorting and classifying them according to different criteria based on topic relevance, country of origin and year of publication.

The literature reflects that Moringa contains all necessary macro, micro-nutrients and bioactive compounds (terpenoids, polyphenols, flavonoids, glucosinolates, alkaloids, glycosides and carotenoids). Scientific studies illustrate that M. oleifera and its bioactive constituents could play a vital role in the prevention of several chronic and degenerative diseases associated with oxidation stress. The recent upsurge in consumer interest for health foods has opened up new vistas for plant products containing bioactive compounds in different food formulations.

This paper highlights phytochemicals, pharmacological properties, bio-accessibility, food and industrial applications of Moringa. Moringa pods are traditionally preferred for enlarged liver and spleen, intestinal worms, weakness, neurological disorders and skin disease. A seed is natural and an inexpensive coagulant used to remove organic particles from water.

The purpose of this paper is to explore barriers and benefits of establishing relationships between humanitarian organizations (HOs) and logistics service providers (LSPs) in order to improve humanitarian disaster relief operations (DROs). The perceptions of a variety of actors are explored to determine key factors which influence collaboration.

This study comprises of qualitative and quantitative methodological approaches. A comprehensive literature review was undertaken alongside an online survey with a variety of respondents. Descriptive statistics, data visualization and qualitative data analysis were implemented to analyse survey results. A follow-up survey and interviews with LSPs validated the results.

The research presents the opinions of a variety of actors involved in DROs and reveals barriers which affect HO/LSP collaboration. Explanations for these barriers and possible solutions to mitigate them are disclosed. The findings also uncover gaps between research and practice; providing new insights into behaviour in the humanitarian field.

The authors provide an in-depth understanding of the barriers and challenges faced in this field and suggest a reevaluation of corporate decision making in order to increase trust between LSPs and HOs. The authors identify future research topics including the impact of donors and military organizations on HO decision making, and analysis of variables which may affect the formation of collaborative partnerships.

The authors introduce a unique empirical insight into the perspectives of HOs, LSPs and academics and offers suggestions for mitigating the numerous barriers associated with successful collaborative partnerships between HOs and LSPs.
