Fit between humanitarian professionals and project requirements: hybrid group decision procedure to reduce uncertainty in decision-making

Choosing the right professional that has to meet indeterminate requirements is a critical aspect in humanitarian development and implementation projects. This paper proposes a hybrid evaluation methodology for some non-governmental organizations enabling them to select the most competent expert who can properly and adequately develop and implement humanitarian projects. This methodology accommodates various stakeholders’ perspectives in satisfying the unique requirements of humanitarian projects that are capable of handling a range of uncertain issues from both stakeholders and project requirements. The criteria weights are calculated using a two-step multi-criteria decision-making method: (1) Fuzzy Analytical Hierarchy Process for the evaluation of the decision maker weights coupled with (2) Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to rank the alternatives which provide the ability to take into account both quantitative and qualitative evaluations. Sensitivity analysis have been developed and discussed by means of a real case of expert selection problem for a non-profit organisation. The results show that the approach allows a decrease in the uncertainty associated with decision-making, which proves that the approach provides robust solutions in terms of sensitivity analysis

An alternative approach for supplier selection problem with analytic network process

İşletmelerin satınalma fonksiyonuna verdikleri önem, modern üretim sistemleri ve bilgi sistemlerinin gelişimine paralel olarak artış göstermiştir. Bu artışta malzeme maliyetlerinin kar üzerindeki etkisi büyük önem taşımaktadır. Satınalma fonksiyonunun önemli modüllerinden biride tedarikçi seçimidir. Tedarikçi seçimi “yapalım mı?, alalım mı?” sorusu ile başlayan ve “alalım” kararına paralel olarak gelişim gösteren bir süreçtir. Bu süreçte analitik yöntemlerin kullanılması yöneticilerin karar vermesini kolaylaştırmakta, aynı zamanda doğru kararların verilmesine de katkı sağlamaktadır. Bu çalışmada, Dağdeviren ve Eren [1] tarafından, tedarikçi seçimine yönelik olarak yapılan çalışma Analitik Ağ Süreci ile tekrar modellenmiş ve tedarikçi seçimi problemine alternatif bir çözüm önerilmiştir. Ayrıca ilgili çalışma ile bu çalışmanın sonuçları karşılaştırılmış ve yorumlanmıştır.The importance companies give to the purchasing has increased with the improvement in modern production systems and information systems. This is mainly due to the effect of the material cost on profit. One of the most important moduls of the purchasing function is supplier selection, that is a process beginning with the “make” or “buy” question and improving in parallel with the “buy” decision. The use of analytic methods facilitates the decision-making for the managers as well as aiding them to make the right decisions. In this study, the supplier selection problem investigated by Dağdeviren and Eren [1] has been further investigated and an Analytic Network Process approach has been suggested for its solution. The results of these two studies have been compared and commented on

Childhood asthma and its relationship with tonsillar tissue.

The aim of this study was to evaluate the prevalence of asthma among 4-17 years old school children and to determine the relationship between frequent tonsillitis, tonsillar hypertrophy and asthma-related symptoms. A total of 2,000 school children, aged 4-17 years, in Denizli were surveyed using the ISAAC questionnaire; the size of the tonsils was evaluated by physical examination. A total of 1,784 questionnaires were completed giving an overall response rate of 89.2%. The prevalence of lifetime wheezing, 12-month wheezing and lifetime doctor-diagnosed asthma were 16.4%, 6.2% and 1.7%, respectively. The prevalence of frequent tonsillitis and tonsillar hypertrophy were 19.9% and 3.4%, respectively. Tonsillar hypertrophy was positively correlated with a history of frequent tonsillitis. Frequent tonsillitis and tonsillar hypertrophy could be evaluated as risk factors for asthma due to their significant association with asthma-related symptoms

Mediating role of loneliness and organizational conflict between work overload and turnover intention

20th Congress of the International Ergonomics Association, IEA 2018 -- 26 August 2018 through 30 August 2018 -- 216789The fact that organizations offer employees a positive organizational climate not only increases employees’ happiness levels but also raises the level of creativity of employees. When it is thought that the only way for organizations to survive in a competitive environment is innovative and creative applications, the positive dynamics within the organization once again emerges. This research focuses on negative behaviors such as work overload, loneliness, organizational conflict and turnover intention which affect employees’ creativity and it aims to discover the mediating role of loneliness and organizational conflict between work overload and turnover intention. In the present research, a survey was conducted including 145 service sector employees. To analyze the demographic characteristics of the participants, internal consistency and correlations of scales, SPSS 22.0; and to test the mediating role, SmartPLS 2.0 were used. According to the analysis results; it is determined that between work overload and turnover intention, loneliness and organizational conflict have a mediating role. When all the results are evaluated together, work overload in the organization forces employees to extreme behavior and it is found that employees feel loneliness or conflict, and as a result, their turnover intention increases. Related to this, it is possible to say that the overloaded employees get further away from creativity. © Springer Nature Switzerland AG 2019.2-s2.0-8505181227
