Background Relative to other occupational groups in Britain, construction workers have a high incidence of skin cancer attributable to sun exposure. The importance of sun safety measures to minimize the risk of skin cancer is recognized in the literature; however, little is known about the factors associated with their use by construction workers. Knowledge in this area could help inform interv...

The study explores inequalities in the utilization of delivery care services in different administrative divisions in Bangladesh, by key socioeconomic factors. It estimates the extent of the relationship between women’s socioeconomic inequalities and their place of delivery during 2004 and 2007.

Methods A total of 259 patients with JIA, first referred to our hospital from 1980 to1985, were reexamined clinically after median 15 years of disease duration, and by mailed questionnaires after median 23 years. These patients were invited to attend the present study. All patients were assessed by questionnaires, and those with signs of active disease after 15, 23 and/or 30 years were invited ...

In this work we analyze the living arrangements of elderly unmarried women in Italy. We use data from three surveys, collected in 1990, 1994, and 1995 by the Italian statistical agency ISTAT. We consider unmarried women aged 65 and older, and three household types (living alone, with children, or with others), taking into account the availability of children with whom they might share a househo...

This paper proposes an optimal allocation problem with ramified transport technologies in a spatial economy. Ramified transportation is used to model network-like branching structures attributed to the economies of scale in group transportation. A social planner aims at finding an optimal allocation plan and an associated optimal allocation path to minimize the overall cost of transporting comm...

This increase is evident online as people are using Twitter to assert their digital citizenship by voicing their opinions regarding President Donald J. Trump and demonstrating solidarity with various civic movements. President Trump’s election has caused many people to recognize how policies impact their ...

Often, in dynamical systems, such as farmer’s crop choices, the dynamics is driven by external nonstationary factors, such as rainfall, temperature, and economy. Such dynamics can be modelled by a nonstationary Markov chain, where the transition probabilities are logistic functions of such external factors. We investigate the problem of estimating the parameters of the logistic model from data,...

Due to growing expectations for quality and safety of food products and an increasing demand for more transparent food supply chains, pork production faces new challenges. In the course of this development, chain-wide communication has gained importance in agribusiness. Nonetheless, existing approaches focus primarily on information supply, whereas the use of information for managerial decision...

This paper presents the process of derivation and development of a spatial multinomial logit model and its application to a housing type choice problem. Over the past few years, a relatively small body of research was developed that tries to capture the spatial and temporal dependencies across decision-makers and alternatives. While temporal dependencies are often considered especially in dynam...
