Dynamic temporary blood facility location-allocation during and post-disaster periods

The key objective of this study is to develop a tool (hybridization or integration of different techniques) for locating the temporary blood banks during and post-disaster conditions that could serve the hospitals with minimum response time. We have used temporary blood centers, which must be located in such a way that it is able to serve the demand of hospitals in nearby region within a shorter duration. We are locating the temporary blood centres for which we are minimizing the maximum distance with hospitals. We have used Tabu search heuristic method to calculate the optimal number of temporary blood centres considering cost components. In addition, we employ Bayesian belief network to prioritize the factors for locating the temporary blood facilities. Workability of our model and methodology is illustrated using a case study including blood centres and hospitals surrounding Jamshedpur city. Our results shows that at-least 6 temporary blood facilities are required to satisfy the demand of blood during and post-disaster periods in Jamshedpur. The results also show that that past disaster conditions, response time and convenience for access are the most important factors for locating the temporary blood facilities during and post-disaster periods

A new focus on risk reduction: an ad hoc decision support system for humanitarian relief logistics

Particularly in the early phases of a disaster, logistical decisions are needed to be made quickly and under high pressure for the decision‐makers, knowing that their decisions may have direct consequences on the affected society and all future decisions. Proactive risk reduction may be helpful in providing decision‐makers with optimal strategies in advance. However, disasters are characterized by severe uncertainty and complexity, limited knowledge about the causes of the disaster, and continuous change of the situation in unpredicted ways. Following these assumptions, we believe that adequate proactive risk reduction measures are not practical. We propose strengthening the focus on ad hoc decision support to capture information in almost real time and to process information efficiently to reveal uncertainties that had not been previously predicted. Therefore, we present an ad hoc decision support system that uses scenario techniques to capture uncertainty by future developments of a situation and an optimization model to compute promising decision options. By combining these aspects in a dynamic manner and integrating new information continuously, it can be ensured that a decision is always based on the best currently available and processed information. And finally, to identify a robust decision option that is provided as a decision recommendation to the decision‐makers, methods of multi‐attribute decision making (MADM) are applied. Our approach is illustrated for a facility location decision problem arising in humanitarian relief logistics where the objective is to identify robust locations for tent hospitals to serve injured people in the immediate aftermath of the Haiti Earthquake 2010.Frank Schätter, Marcus Wiens and Frank Schultman

Causes of death of patients with laryngeal cancer.

Contains fulltext : 127549.pdf (publisher's version ) (Closed access)Despite remarkable advances in the care of patients with laryngeal cancer over the past several decades, including a growing awareness of therapeutic complications and attention to quality of life, little is known about the causes of mortality in this population. In addition to the laryngeal malignancy itself, acute and late or chronic treatment-associated causes, second primary cancers, intercurrent disease and psychosocial factors are all responsible for patient morbidity and mortality. We examine the current literature related to the causes of death in patients with laryngeal cancer, in the hope of guiding future interventions to improve the longevity and quality of life of individuals with this cancer.1 maart 201

Effects of culture on women entrepreneurs' success: a cross country study.

Most entrepreneurs define success as business growth. However, for women entrepreneurs, success incorporates various aspects and meanings. Thus, success is by far one of the most complex concepts in the field of entrepreneurship. Because women entrepreneurs’ success is a multifaceted concept, it has, therefore, multiple interpretations. Moreover, researchers across the world provided various definitions correlated to qualitative or quantitative approaches to this phenomenon. In the meantime, cross-country studies revealed multiple factors affecting women entrepreneurs’ success. A crucial factor affecting the success of women entrepreneurs across the world is the culture. Thus, studies conducted across the globe revealed various types and dimensions of culture and indicated different effects of culture on women entrepreneurs’ success. The authors discovered the significance of gender for interpretation of success and culture. The purpose of the study is to examine various effects of culture on women entrepreneurs’ success in a cross-country context and to design an integrative, holistic theoretical framework that enhances our understanding of success for women entrepreneurs from a gender perspective and explains the effects of culture. The value of designing such theoretical framework is the increase in knowledge with regard to cultural impact on women entrepreneurs’ success and the request for viable solutions to be designed by policy makers, which can help women entrepreneurship to grow
