    Nowadays, online shopping intentions and behaviors which have an important place in consumption habits, have become increasingly important for businesses. One of the most important models examining consumers' behavior in online shopping channels is the Technology Acceptance Model. While this model is basically composed of perceived usefulness, perceived ease of use and intention of online shopping, it also allows different components to be included in the model. For this reason, an extended Technology Acceptance Model which includes the perceived product risk was used in the study. The data used in the study were collected from 355 people by convenience sampling method. Research hypotheses have been tested with Structural Equation Modelling based on Partial Least Squares Method (PLS-SEM). According to result of the analysis, it was found that the perceived ease of use had a positive effect on both perceived usefulness and online shopping intention. Nonetheless it was found that perceived product risk had a negative impact on perceived usefulness and intention to use online shopping. The results also showed that perceived usefulness has a positive and significant effect on consumers’ intention to use online shopping.Günümüzde tüketim alışkanlıkları içinde önemli yeri olan online alışveriş niyet ve davranışlarının incelenmesi, işletmeler açısından giderek daha da önemli hale gelmiştir. Tüketicilerin online alışveriş kanallardaki davranışlarını inceleyen en önemli modellerden bir tanesi de Teknoloji Kabul Modelidir. Bu model temelde algılanan fayda, algılanan kullanım kolaylığı ve online alışveriş niyeti bileşenlerinden oluşmakla birlikte, farklı bileşenlerin de modele dâhil edilmesine imkân tanımaktadır. Bu nedenle çalışmada algılanan ürün riskini de içeren genişletilmiş bir Teknoloji Kabul Modeli kullanılmıştır. Araştırmada kullanılan veriler 355 kişiden kolayda örnekleme yöntemiyle toplanmıştır. Araştırmada ileri sürülen hipotezlerin test edilmesinde Kısmi En Küçük Kareler Yöntemine Dayanan Yapısal Eşitlik Modellemesinden yararlanılmıştır. Yapılan analiz sonucunda algılanan kullanım kolaylığının hem algılanan fayda hem de online alışveriş niyeti üzerinde pozitif yönlü etkisi olduğu, algılanan ürün riskinin ise algılanan fayda ve online alışveriş niyetini negatif yönde etkilediği yönünde bulgular elde edilmiştir. Çalışma sonuçları ayrıca algılanan faydanın, tüketicilerin online alışveriş niyetleri üzerinde pozitif yönlü ve anlamlı etkisi olduğunu da göstermiştir

Turkey as an emerging market faced considerable monetary and political turbulence in the past decade. Variables from the currency and sovereign debt markets will be the proxies for exchange rate risk and political risks, respectively. Evidence of the risk premiums as a result of the exposure to the equity markets show valuable inferences although statistically significant conclusions are not the majority. These results have many implications for the corporate and portfolio management. This study also provides tools and data that can be utilized by the emerging market researchers.Yılmaz, ÖzerM.S

    A Research on the determination of students' general ınternship problems for associate degree program in tourism and hotel management

    Get PDF
    Turizm ve otel işletmeciliğinde okuyan öğrencilerin turizm sektörüne yönelik görüşleri daha çok staj dönemlerinde şekillenmeye başlamaktadır. Ancak staj sürecinde zaman zaman gerek eğitim kurumu, gerek işletme ve gerekse öğrenci kaynaklı birtakım problemler yaşanmaktadır. Yaşanan problemler ya stajın verimsizliğine ya da kalifiye personelin turizm sektöründen uzaklaşarak farklı alanlarda kariyer yapma isteğine yol açmaktadır. Bundan yola çıkarak, bu çalışmanın amacı ön lisans düzeyinde turizm eğitimi alan, staj deneyimine sahip öğrencilerin, staj sürecinde staj yaptıkları işletmelerden ve öğrenim gördükleri kurumlardan kaynaklanan sorunlar hakkında öğrencilerin kişisel düşünce ve deneyimlerinin alınarak, yaşanan sorunların çözümüne yönelik görüşler sunmak ve turizm eğitiminin daha verimli hale getirilmesidir. Araştırmanın kapsamını Afyon Kocatepe Üniversitesi Turizm ve Otel İşletmeciliği Programı önlisans öğrencileri içerisinde stajını tamamlayan öğrenciler oluşturmaktadır. Çalışmada konu hakkında değerlendirmeler yapabilmek için nitel araştırma yöntemlerinden odak grup görüşme tekniğiyle veriler toplanıp yorumlanmaya çalışılmıştır. Görüşmenin ilk aşamasında öncelikle bir açıklama konuşması yapılarak görüşmecilerin birbirleriyle tanıştırılması sağlanmıştır. İkinci aşamasında görüşme başlıkları görüşmecilere bildirilerek konu hakkında her birinin kısa görüşleri alınarak, öncelikle yarı yapılandırılmış sorular daha sonra görüşme sürecinde ortaya çıkan yapılandırılmamış sorular sorularak grubun sorular karşısında kendi aralarında tartışmaları sağlanmıştır. Böylece konu hakkında benzer ve farklı görüşler tespit edilmeye çalışılmıştır. Çalışmanın son bölümünde ise yapılan odak grup görüşmesi çalışmasından elde edilen birincil veriler değerlendirilerek öğrencilerin staj uygulamalarında karşılaştıkları çeşitli sorunlar hakkında sonuçlar elde edilmiştir. Elde edilen bulgular değerlendiğinde turizm öğrencilerinin staj dönemlerinde pek çok olumsuzluklarla karşılaşmalarına rağmen mesleki eğitim içerisinde stajın önemli ve mutlaka uygulanması gereken bir eğitim olması noktasında birleştiklerini görülmüştür. Öğrencilerin staj sorunları hakkında en mağdur oldukları ortak konu başlıkları ise; sektörde eğitimli insan sayısının azlığı ve bu durumun staj çalışmalarını olumsuz etkilemesi, ucuz işgücü olarak görülmeleri, fazla iş yükü ve kadrolu çalışan muamelesi ile çalışma saatleri ve ücret olarak tespit edilmiştir. Çalışmanın son bölümünde, ortaya çıkan sonuçlar çerçevesinde staj uygulamalarının daha sorunsuz uygulanabilir hale getirilebilmesi için çözüm önerileri sunulmuştur.The opinions of the students studying in tourism and hotel management are starting to be shaped mostly during the internship period. However, there are some problems in the internship process time to time caused by the educational institution, business and students. These problems lead to internship inefficiency or desire of qualified personnel to move away from the tourism sector and have a career in different fields. From this point of view, the aim of this study is to make the tourism education more productive by taking consideration of the personal thoughts and experiences of the students about the problems arising from students, who have experience of internship in the pre-license level of this study, arising from the enterprises they have trained in internship and institutions they have studied. The scope of this research is Afyon Kocatepe University Tourism and Hotel Management Program students that complete their internship in 2014-2015 academic years. In this study, the focus group interview technique was used to collect and interpret qualitative research methods in order to evaluate the data. In the first phase of the interview, an explanatory talk was done and the interviewers were introduced to each other. In the second phase, interview topics were reported to the interviewees by taking brief opinions of each of them on the issues, and semi-structured questions were asked at first. Later on unstructured questions arise out of the interview process were asked to interviewers to enable discussions among them. Thus, attempts have been made to identify similar and different views on the subject. In the last part of the study, the primary data obtained from the focus group interview study were evaluated and various problems that students encountered in internship practices were come out as a result. After evaluation, it is seen that tourism students have a lot of problems during the internship periods but they are all agreed at the point of being vocational education training must be practiced. The most common topics that students are aggrieved about internship problems are; low number of educated people in the sector and the negative effects of this situation on their internship works, being seen as cheap labor force, overworked and permanent employee treatment, working hours and wages. In the last part of the study, a solution proposal will be presented in order to make internship applications more smoothly applicable within the framework of the results

Structural Equation Modeling (Partial Least Square Method) and Sobel tests were used to test the hypothesis. As a result of analysis, it has been seen that ethical leadership has positive and significant effect on employees’ perceived organizational climate and work loneliness plays a partial mediation role in this relationshi

    Trajectory generation with natural ZMP references for the biped walking robot SURALP

    Get PDF
    Bipedal locomotion has good obstacle avoidance properties. A robot with human appearance has advantages in human-robot communication. However, walking control is difficult due to the complex robot dynamics involved. Stable reference generation is significant in walking control. The Linear Inverted Pendulum Model (LIPM) and the Zero Moment Point (ZMP) criterion are applied in a number of studies for stable walking reference generation of biped robots. This is the main route of reference generation in this paper too. We employ a natural and continuous ZMP reference trajectory for a stable and human-like walk. The ZMP reference trajectories move forward under the sole of the support foot when the robot body is supported by a single leg. Robot center of mass (CoM) trajectory is obtained from predefined ZMP reference trajectories by Fourier series approximation. We reported simulation results with this algorithm in our previous works. This paper presents the first experimental results. Also the use of a ground push phase before foot take-offs reported in our previous works is tested first time together with our ZMP based reference trajectory. The reference generation strategy is tested via walking experiments on the 29 degrees-of-freedom (DOF) human sized full body humanoid robot SURALP (Sabanci University Robotics Research Laboratory Platform). Experiments indicate that the proposed reference trajectory generation technique is successful

    Get PDF
    Purpose – This paper aims to investigate the effects of various heat treatments on microstructure, hardness, porosity and corrosion properties of the parts. Design/methodology/approach – Hot isostatic pressing (HIP) process, various heat treatments and their combinations were applied to the AlSi10Mg parts produced by direct laser metal sintering (DMLS). Findings – It has been found that the HIP process, which is a post-processing process, reduces the amount of porosity in DMLS-AlSi10Mg material, thus improves corrosion resistance significantly. Originality/value – In this study, the HIP process and subsequent T6 heat treatments were applied to AlSi10Mg parts produced by the DMLS technique. The study aims to increase the corrosion resistance of AlSi10Mg parts by reducing porosity with the HIP process and by altering the microstructure with the T6 process

    Effects of intellectual capital on qualitative and quantitative performance: Evidence from Turkey

    Get PDF
    Intellectual capital is among the new, advanced management notions developed to overcome the inadequacy of previous administrations, to adapt to new situations and forge ahead of the competition. Intellectual capital means the information, experience and skills that offer advantage in competition and reveal the values existing within the structure of an enterprise. These values also exist in the relationship between  the enterprise and the environment  and  with the employees. Although some research studies on intellectual capital (IC) have been conducted, to date no research has been carried out on the effects of IC on qualitative and quantitative organizational performance. For this reason, IC and its effects on firm performance (both qualitative and quantitative) were evaluated in this study. Following the evaluation of the intellectual capital and its sub-elements, the differentiation of the sub-elements is made. Then the reliability and validity of these sub-factors are calculated. The intellectual capital model has been tested by the structural equality model (SEM).  According to research results, IC explains 92  per cent of a firm’s performance. The effect of IC on qualitative performance is 0,84, while on quantitative performance it is 0,72. RC impresses qualitative performance with coefficient 0,94, quantitative performance with coefficient 0,60; HC impresses qualitative performance with coefficient 0,92, quantitative performance with coefficient 0,54 less; SC impresses qualitative performance with coefficient 0,90, quantitative performance with coefficient 0,53. According to the results of the research, IC affects both the qualitative and the quantitative performance of firms by supplying extensive knowledge to the managers

    A Rare Case: Improved Heart Failure with Anti-Complement Therapy in Complement-Dependent Hemolytic Uremic Syndrome

    Get PDF
    MakaleWOS:000925209300014xtrarenal involvement occurs in approximately 20% of patients with complement-mediated hemolytic-uremic syndrome. The involvement is usually of the nervous system, and cardiac involvement occurs in 3%-10% of patients. Cardiac manifestations vary, including myocardial infarction, cardiomyopathy, and acute decompensated heart failure. Among these patients, thrombotic microangiopathy-related cardiac dysfunction is mainly due to the continuous activation of the complement system, which leads to endothelial damage and thrombosis in the coronary microvessels. We wanted to highlight the importance of cardiac evaluation at the time of diagnosis or during follow-up in thrombotic micro-angiopathy patients by presenting a case of heart failure with low ejection fraction in a 24-year-old young patient in whom we detected complement-mediated hemolytic-uremic syndrome, a secondary mutation of complement factor H receptor. It is still an unknown issue because of the rarity of cardiac involvement in complement-mediated hemolytic-uremic syndrome patients. Primary myocardial involvement is increasingly recognized as a possible concomitant feature of hemolytic-uremic syndrome. Failure to perform a detailed cardiac evaluation both at diagnosis and during follow-up in complement-mediated hemolytic-uremic syndrome patients can lead to fatal outcomes. Anti-complement therapy can also lead to good cardiac outcomes in these patients
