Consumer complaining behavior in hospitality management
No full textThe purpose of this study is to investigate the impacts of assertiveness, aggressiveness, and perceived risks on consumer complaining behavior (CCB) in the tourism and hospitality sector. This research utilized a quantitative methodology through the implementation of a two-stage study based on surveys. Study 1 examined the impacts of assertiveness, aggressiveness, and perceived risks on CCB in the context of low-quality summer vacation, while Study 2 further investigated the relationships in the research model by replicating the survey within the framework of high-quality summer vacation. The results were then analyzed through factor and regression analyses. Both of the studies demonstrated that assertiveness positively influences CCB directly and also indirectly via the mediating effect of perceived risks. It was found that aggressiveness positively influences CCB when consumers have high service quality expectations but when they have low expectations for service quality, it is insignificant.WOS:0006782998000012-s2.0-85111447985Social Sciences Citation IndexSocial Sciences Citation IndexArticle; Early AccessUluslararası işbirliği ile yapılmayan - HAYIRTemmuzYÖK - 2020-2
DSA Topluluklarının Beyin-Bilgisayar Arayüzleri için Uyarlamalı Güçlendirilmesi
No full textSteady-state visual evoked potentials (SSVEP) are commonly used in brain computer interface (BCI) applications such as spelling systems, due to their advantages over other paradigms. In this study, we develop a method for SSVEP-based BCI speller systems, using a known deep neural network (DNN), which includes transfer and ensemble learning techniques. We test performance of our method on publicly available benchmark and BETA datasets with leave-one-subject-out procedure. Our method consists of two stages. In the first stage, a global DNN is trained using data from all subjects except one subject that is excluded for testing. In the second stage, the global model is fine-tuned to each subject whose data are used in the training. Combining the responses of trained DNNs with different weights for each test subject, rather than an equal weight, provide better performance as brain signals may differ significantly between individuals. To this end, weights of DNNs are learnt with SAMME algorithm with using data belonging to the test subject. Our method significantly outperforms canonical correlation analysis (CCA) and filter bank canonical correlation analysis (FBCCA) methods.WOS:0008081007000842-s2.0-85111422982Conference Proceedings Citation Index – ScienceProceedings PaperUluslararası işbirliği ile yapılmayan - HAYIRHaziranYÖK - 2021-2
Teachers' Attention to and Flexibility with Referent Units
No full textAttending to the whole unit that a number refers to in a mathematical problem situation and showing flexibility in coordinating different units are foundational for mathematical understanding. In this study, we explored teachers’ attention to and flexibility with referent units in situations involving fractions and fraction multiplication. Using data collected across the USA from 246 mathematics teachers in Grades 3–7 where fractions are taught, we found that teachers’ attention to and flexibility with referent units were related to each other as well as to teachers’ overall knowledge of fractions.WOS:0006692909000012-s2.0-85109328142Social Sciences Citation IndexArticle; Early AccessUluslararası işbirliği ile yapılan - EVETJulyYÖK - 2020-2
Voluntary simplicity: a content analysis of consumer comments
No full textPurpose -
The voluntary simplification (VS) movement has stemmed from Western societies and gained momentum in the 1980s, but the trend has failed to become a primary perspective for most consumers. The accompanying concepts of conscious consumption, minimalism and accepting that sometimes “less is more” are still vivid in the digital era. The purpose of this study is to provide a deep and recent understanding of the consumer comments about minimalism in Turkey and examine their associations with the prominent themes in the VS literature.
Design/methodology/approach -
Consumer comments posted on online platforms were analyzed by content analysis and word frequency analysis.
Findings -
Consumer comments were in parallel to the themes in the VS literature and were classified under personal growth, material simplicity, sustainability, proper technology usage and self-sufficiency categories. Personal growth, material simplicity and sustainability were the first three dimensions mentioned. The prominent sub-themes that emerge from data were psychological well-being, inner peace, freedom, meaningful experiences and getting rid of belongings. A word frequency analysis pointed out that “life” and “owning” were the evident words in the personal growth category, “purchasing things” were mostly mentioned in the material simplicity category and “plastic litter” and “excessive consumption” were the prominent concerns in the sustainability category.
Originality/value -
VS required further research in different national contexts. Besides, an analysis of the dimensions of VS was needed. This study contributes by providing recent and rich findings from a developing country, connecting them with the VS themes in the literature and suggesting a conceptual framework enriched by sub-themes that emerged from data.WOS:0006614306000012-s2.0-85107727895Emerging Sources Citation IndexArticle; Early AccessUluslararası işbirliği ile yapılmayan - HAYIRHaziranYÖK - 2020-2

Özgür irade inancının cezalandırma davranışına etkisi
No full textÖzgür irade kavramı kişinin aldığı kararlarda ve gerçekleştirdiği davranışlarda ilk neden olabilme yetisini ifade eder. Kişi, önceki herhangi bir belirlenmiş olguya mutlak anlamda tabi olmaksızın karar alabiliyor ve davranışta bulunabiliyorsa özgür iradesiyle hareket ediyor demektir. Bu içeriğiyle özgür iradenin gerçeklikte mevcut olup olmadığı ya da özgür iradenin varlığından söz ede- bilmek için ilk neden olma özelliğinin tüm karar ve davranışlara yayılmasının gerekip gerekmediği soruları üzerinde filozoflar Antik çağlardan beri tartışıyorlar. 20. Yüzyılın son çeyreği iti- barıyla, davranışsal ve bilişsel nörobilim ile davranış psikolojisi dalları kapsamındaki araştırmacılar da söz konusu tartışmaya müdahil oldular. Bu müdahale ile özgür irade tartışması deney- sel, uygulamalı çalışmalar aracılığıyla da yürütülebilir hale geldi.Eylü
E-ticaret sitesi için collaborative filtering ALS algoritması ile ürün önerme
No full textIn this project, a machine learning recommendation model is created for an e-commerce company which runs a customer to customer business. The raw data consisted order reviews, order details, product like event information and product details. The explicit and implicit feedbacks are used together and a rating generation logic per user-product couple is applied to create the source data of the model by using Google Cloud BigQuery tool. The ALS algorithm which uses matrix factorization is applied for predicting the top items which have highest ratings for each user. PySpark which is Apache Spark’s python API is used for implementing the ALS model. The best hyperparameters are determined comparing the root mean square error results by using grid search and cross validation and 0.78 of RMSE is reached. The predictions for the empty ratings are sorted then top rated 10 products are taken as recommendations. The evaluation of the model is done by comparing those recommendations with the user preferences. The user preferences are specified by using averagely top rated product categories and most interacted product categories in count. The recommendations are observed to be consistent with the user preferences
The Russian Federation: Return to the global power position, the Syrian crisis case study
No full textBu tez çalışmasının yapılmasının amacı Soğuk Savaş'tan sonra Rusya Federasyonu'nun günümüzde küresel güç potansiyeline erişip erişmediği ve pratikte bu bulguların Suriye krizi çerçevesinde mevcut olup olmadığı araştırılarak alanyazına katkıda bulunmaktır. Bunun yanında bu tez çalışmasının önemi küresel güç potansiyeline sahip bir devletin hangi özelliklere sahip olduğunu görmek ve bu kapsamda RF'nun bu vasıflara sahip bir devlet olup olmadığını vaka çalışması bağlamında incelemektir. Bu çerçevede RF'nun milli güç kapasiteleri incelenmiştir. Çünkü bir devletin sahip olduğu milli güç o devleti uluslararası sistemde belirli yere konumlandırmaktadır. Bir devlet gücünü ne kadar arttırırsa dünya siyasetinde o kadar söz sahibi olmaktadır. Dolayısıyla elde edilen bulgular ışığında RF'nun kurulduğundan beri sahip olduğu güç kapasitesinin hangilerinin küresel güç olma özellikleri gösterdiği veya gösteremediği anlaşılmaya çalışılmıştır. Bu milli güçler ise sırasıyla şunlardır. Siyasi yapısı, coğrafyası, demografisi, ekonomisi, askeri gücü, yumuşak gücü ve psiko sosyal güçtür. Siyasi yapı devletin rejiminin, kurumların güçlü bir yapıya sahip olup olmadığını gösteren verilerin ve devlet ile halk arasındaki ilişkinin incelenmesi amacıyla araştırılmıştır. Coğrafya ise bir devletin hakim olduğu alanların kendisine sağlamış olduğu birtakım kazınımların ve noksanlıkların olduğu gerekçesi ile incelenmiştir. Rusya Federasyonu'nun ekonomik yapısındaki güçlükler ve zayıflıklar ise dış politikasına olan etkileri nedeniyle önemli hususlardır. Askeri güç, RF için dünya siyasetinde etkin olmak ve küresel güce dönüşme de en önem verdiği alan olması bakımından mühimdir. Yumuşak güç, RF'nun yabancı kamuoyu açısından edinmiş olduğu imajın küresel güç olma da bir faktör olması dolayısıyla araştırılmıştır. Bu milli güç kapasitesini RF 1990'lı yıllardan beri geliştirmektedir. Mevcut güç kapasitesini dış politikada ne kadar gerçekliğe dönüştürdüğünü anlamak için Suriye krizi bir vaka çalışması olarak ele alınmıştır. Elde edilen bulgular sonucunda RF Suriye krizinde siyasi, diplomatik ve sahada oldukça etkin bir varlık gösterdiği ve ABD gibi bir küresel gücü Suriye'de pasifize etmeyi başardığı anlaşılmıştır. Fakat RF'nun milli güç kapasitesi incelendikten sonra varılan sonuç şudur. Siyasi, askeri, enerji ve coğrafya bakımından Rusya Federasyonu küresel güç bir devlet özellikleri gösterse de ekonomi, teknoloji ve yumuşak güç bakımından RF'nun gücü henüz daha olgunlaşmamıştır. Dolayısıyla RF şu an ki potansiyeli ile büyük güç konumundadır.The purpose of this thesis is to make contributions to literature by analizing whether Russian Federation has reached its global power potential after the Cold War and whether this potential exists in practice within the framework of the Syria crisis. In addition, the importance of this thesis is to figure out the traits of a state with superpower potential and analyse in that scope whether RF is a state with these traits regarding the case study. In this framework, the national power capacities of Russian Federation were examined cautiously. Because the national power possessed by a state positions it in a certain place in the international system. A state can have a say in world politics as much as it enhances the number of areas in which it is strong. Hence, in light of acquired findings it was tried to be understood which its power capacity had global power characteristics or not since its establishment. These national powers are the following: The political structure, geography, demography, economy, military power and soft power. The political structure was researched in purpose of examining the relations between state and nation and the datas indicating whether the regime of state and its' institutions have robust structure. The geography, on the other hand, was researched on the grounds that there are some acquisitons and deficiencies of the areas dominated by the state. The strengths and weaknesses of RF are significant issues for the reason of their impacts to the foreign policy of Russian Federation. The military power is so important for RF in terms of being efficient in world politics and being the most important field in its transformation into global power. Soft power was examined for the fact that it was a factor concerning the image that RF has in the eyes of foreign public. Russian Federation has been developing its national power capacity since 1990's. The Syrian crisis was evaluated as a case study in order to understand how much RF transforms the current power capacity into a reality in its foreign policy. As a result of the findings RF has efficently made his presence felt in terms of political, diplomatic and field in the Syrian crisis and succeded to pacify USA, a global power, in Syria crisis. However after evaluating the national power capacity of RF our conclusion is the following. Although Russian Federation is a superpower concerning political, military, energy and geography, RF's power hasn't matured yet regarding economic, technology and soft power. Therefore RF, with its current potential, is a big power
