The n-job, m-machine flow shop scheduling problem is one of the most general job scheduling problems. This study deals with the criteria of makespan minimization for the flow shop scheduling problem. Artificial Immune Systems (AIS) are new intelligent problem solving techniques that are being used in scheduling problems. AIS can be defined as computational systems inspired by theoretical immunology, observed immune functions, principles and mechanisms in order to solve problems. In this research, a computational method based on clonal selection principle and affinity maturation mechanisms of the immune response is used. The operation parameters of meta-heuristics have an important role on the quality of the solution. Thus, a generic systematic procedure which bases on a multi-step experimental design approach for determining the efficient system parameters for AIS is presented. Experimental results show that, the artificial immune system algorithm is more efficient than both the classical heuristic flow shop scheduling algorithms and simulated annealing.

The aim of this study is to analyze the effect of education level on the job satisfaction. The relationships between the educational level and job satisfaction were tested with hypotheses; H0: There isn't a relationship between education level and job satisfaction. H1: There is a relationship between education level and job satisfaction. To measure job satisfaction, a questionnaire comprising a slightly modified form of a popular job satisfaction questionnaire was used. The study was conducted on a total of 600 workers, working in 30 four and five stars hotels. All of the questionnaires were picked up because the questionnaires were administered individually by the students of tourism department. 69 percent of the responses were taken from graduated and vocational school students of higher education, 31percent from primary and secondary schools. Consequently, a positive relationship was found between job satisfaction and education level. The results suggest that managers should find new methods to increase education level of their staff and develop work context parallel to education level.

Son yıllarda pek çok merkez bankası para politikasının şeffaf olması konusuna büyük bir önem vermiştir. Merkez bankasının amacındaki netlik ve bu amaca nasıl ulaşılacağı konusundaki şeffaflık, belirsizliği ortadan kaldırarak ekonomik birimlerin gelecekle ilgili doğru kararlar almasını kolaylaştırmaktadır. Enflasyon düzeyini belirleyen önemli faktörlerden biri olan enflasyonist beklentiler para politikasında şeffaflık sağlanması sonucu azaltılabilmekte ve merkez bankasının enflasyon hedefiyle uyumlu bir seviyeye getirilebilmektedir. Bu çalışmada, para politikasında şeffaflık sağlanarak enflasyonist beklentilerin yönlendirilebildiği ve bu politikanın enflasyonla mücadelede etkili sonuçlar doğurduğu gösterilmektedir.

A survey was conducted in Muğla Region to find out, on one hand, whether there are differences between tourists' evaluations of hospitalities' performances and employees self-evaluations, and on the other hand whether evaluations of tourists from various countries differ. Tourists' and service providers' evaluations in six constructed areas differed significantly only in two areas: "attitudes" and "behaviors and skillfulness". Tourists' evaluations in the mentioned areas are significantly higher than those of employees. When it comes to the second issue, the study shows that there are some significant differences between Russian tourists' evaluations and Western nationalities' evaluations, those of British, Germans, Dutch, and Scottish. Also, Belgians' evaluations were set apart from those of the mentioned nationalities in "attitude of employees".

Enformasyon teknolojilerinin yönetimi, bu teknolojilerin sağladığı faydaların artmasıyla birlikte, kurumlar için gittikçe daha fazla önem kazanmaktadır. Kurumlarda yaygın olarak uygulanan Dengelenmiş Puan Kartı (DPK) ise strateji odaklı bir yönetim sistemini ifade etmektedir. Bu çalışmada, DPK'nın enformasyon teknolojileri yönetimindeki fayda potansiyelleri incelenmektedir. İlk olarak, enformasyon teknolojisi bölümlerinin değişen nitelikleri ve yeni rolleri değerlendirilmektedir. Ardından, DPK'nın genel özellikleri ve temel fonksiyonları ele alınmıştır. Üçüncü bölümde ise DPK'nın enformasyon teknolojilerine uyarlanması bağlamındaki farklı yaklaşımlar tartışılmaktadır.
