Unaddressed problems and research perspectives in scheduling blood collection from donors

Many optimisation problems arise in managing the Blood Donation (BD) supply chain. Most of them have been addressed in the literature, while other problems, e.g. donation scheduling, have not been sufficiently addressed so far. However, blood collection from donors may have a disruptive impact on the entire BD supply chain if not properly managed. For example, scheduling donation appointments based on some system metrics may improve the flow of blood units through the BD supply chain and increase the quality of service perceived by donors. In this short communication, we present the donation scheduling problem and highlight the lack of work in the literature that deals with this problem. Then, we analyse the impact of an unbalanced flow of blood units on the BD system and the benefits that may derive from a suitable appointment scheduling. Finally, we propose suggestions for future research in BD collection scheduling that may improve the BD process.

Convex Ordering for Bivariate Distributions

An attempt is made to extend well-known univariate notion of convex ordering to bivariate case. A convex ordered family for bivariate distributions is then introduced and its properties are examined.     

Turkey: a pilot study of elder mistreatment in a convenience sample

Attitudes towards elder abuse were explored through a survey on International Perspectives on Family Violence and Abuse in a Turkish convenience sample of 25 females and 14 males, ranging in age from 22 to 58. Participants gave examples of behaviors considered in their culture to be extremely abusive, moderately abusive, and mildly abusive from an adult child toward his or her older parent. Responses were coded into four major categories of abuse, each of which had several subcategories: psychological aggression (including the subcategories of verbal aggression, emotional abuse, disrespect, disobedience, power assertion, blame, and imprisonment), neglect (including physical neglect, psychological neglect, abandonment, and putting the older individual into a nursing home), physical aggression (including beating and hitting), and mistreatment related to goods and services (including economic demands, economic withholding, and labor). The most common examples of extreme abuse were neglect, particulary physical neglect, followed by physical abuse. At the moderate and mild levels, various forms of psychological aggression were most commonly mentioned. The only significant gender difference was that men listed more instances of verbal aggression as examples of extreme abuse than women. A positive correlation was found between age and the number of abandonment examples at the extreme level. Results were interpreted from a cultural perspective.     

Mediator role of intergroup anxiety in relationship between the social contact,intercultural sensitivity and attitudes towards Syrians among Turkish local society

Turkey is the country with the highest Syrian refugee population hosted in the world. Social acceptance of immigrants by the local community is as important as the social cohesion of immigrants regarding the social integration process. The aim of the current study was to examine the role of social contact, intercultural sensitivity, intergroup anxiety, gender, age, education, abroad experience and city on attitudes of Turkish local society towards Syrians. In this regard, data were collected from 207 local community members living in Ankara and Adana provinces of Turkey. According to the analysis, qualitative social contact, intercultural sensitivity and intergroup anxiety predicted the attitudes of the local community towards Syrians. In addition, intergroup anxiety had a mediating role between qualitative social contact, intercultural sensitivity and attitudes towards Syrians. When close social contact and intercultural sensitivity of Turkish local society increase, intergroup anxiety decreases and it increases positive attitudes towards Syrians. Lastly, while there was no gender difference in attitude towards Syrians, females were higher in intercultural sensitivity than males.
