The Status of Criminological Theories in Turkey: A Brief Account

The aim of this study is to evaluate the status of criminological theories in Turkey and to present some recommendations to follow in the future. Unfortunately, some sub-disciplines in social sciences in Turkey have been relatively less developed. This is especially valid for criminology or sociological studies of crime. More relavant to this paper, there have been a limited number of tests of western-originated criminological theories in Turkey. It is suggested that Turkish scholars test all the existing criminological theories in the context of Turkey and, more importantly, tend to develop criminological theories that reflect Turkish realities

ВПЛИВ КОРПОРАТИВНОЇ РЕПУТАЦІЇ НА РИНКОВУ ЦІННІСТЬ, ЕМПІРІЧНІ ДОКАЗИ НА ПРИКЛАДІ ТУРЕЧЧИНИ

The high profitability expectation of the past is replaced with the advantage of sustainable competition in today’s business world. The boundaries of companies and their effects on society have expanded dramatically because of globalization and developments in information technologies, which has in turn raised society’s expectations of companies.  For this reason, investors expect the companies to be sensitive to social issues besides having a high financial performance. The issue of corporate reputation has been discussed by many different disciplines through the years. Most of these studies consider corporate reputation as a strategic asset, and claim that it leads to sustainable competition by increasing financial performance. On the other hand, financial performance recognizes as a part of corporate reputation in some other studies. As a result, the concept of corporate reputation has now become essential for business.This study aims to examine whether the corporate reputation has significant effect on market value of companies. In literature, there are many studies about corporate reputation and financial performance relations. Many studies have demonstrated that there is a positive relationship between corporate reputation and financial performance. This has raised the problematic question of how reputation should be measured. Especially in developed countries, reputation indices are common indicators of reputation. But in Turkey, there are limited studies because of inadequacy of long-term database and measurement scales. In this study, corporate reputation is considered as an intangible asset, shaped by the perceptions of all internal and external stakeholders of corporations which can affect corporate value. To measure corporate reputation, a scale which is composed of 58 different criteria and formed by previous scales has been used. The full sample includes 99 listed companies and 1,188 firm years for 2006-2017. Panel data regression analysis has been used to test the relationship between corporate reputation and market value. The results are consistent with the past studies that highly reputable firms have high market value.цель исследования изучение влияния корпоративной репутации на рыночную стоимость компаний. В литературе имеется много исследований о корпоративной репутации и финансовые бизнес-отношения. Многие исследования показали, что положительные отношения между корпоративной репутацией и финансовой производительностью. Это поставило проблемный вопрос о том, как можно измерить репутацию. Особенно в развитых странах репутационные показатели являются общими показателями репутации. Но в Турции существуют ограниченные исследования из-за неспособности долгосрочной базы данных и измерительной шкалы. В этом исследовании корпоративная репутация считается нематериальным активом, сформированным сознанием всеми внутренние и внешними стейкхолдерами корпораций, которые могут влиять на корпоративное значение. Для измерения корпоративной репутации используется шкала, которая состоит из 58 различных критериев и сформирована предыдущей шкале. До полного образца входят 99 компаний и 1188 фирм с 2006 по 2017 лет. Осуществлен анализ регрессии данных на панели данных для проверки связи между корпоративной репутацией и рыночной стоимостью. Результаты согласуются с предыдущими исследованиями, где фирмы с высокой репутацией имеют высокую рыночную стоимость.Очікування високої рентабельності в минулому замінено перевагою стабільної конкуренції в сучасному діловому світі. Ліміти компанії та їх вплив на суспільство різко поширилось через глобалізацію і розвиток інформаційних технологій, що, в свою чергу, підвищило очікування суспільства компаній. З цієї причини інвестори очікують, що компанії будуть чутливими до соціальних питань, наряду з тим, що вони мають високі фінансові показники. Питання про корпоративну репутацію піднімалося протягом багатьох років в різних дисциплінах. Більшість цих досліджень розглядають корпоративну репутацію як стратегічний актив, і стверджують, що це призводить до стійкої конкуренції за рахунок збільшення фінансової продуктивності. З іншого боку, в деяких інших дослідженнях фінансові результати розглядаються як частина корпоративної репутації. Як наслідок, концепція корпоративної репутації стала важливою для бізнесу.Це дослідження має на меті вивчити чи має корпоративна репутація значний вплив на ринкову вартість компаній. У літературі є багато досліджень про корпоративну репутацію та фінансові бізнес-відносини. Багато досліджень продемонстрували, що є позитивні відносини між корпоративною репутацією та фінансовою продуктивністю. Це поставило проблемне питання про те, як можна виміряти репутацію. Особливо в розвинених країнах репутаційні показники є загальними показниками репутації. Але в Туреччині існують обмежені дослідження через неспроможність довгострокової бази даних і вимірювальної шкали. У цьому дослідженні корпоративна репутація вважається нематеріальним активом, сформованим усвідомленням всіма внутрішні та зовнішніми стейкхолдерами корпорацій, які можуть впливати на корпоративне значення. Для вимірювання корпоративної репутації використовується шкала, яка складається з 58 різних критеріїв і сформована попередньою шкалою. До повного зразка входять 99 компаній та 1188 фірм з 2006 по 2017 років. Здійснено аналіз регресії даних на панелі даних для перевірки зв'язка між корпоративною репутацією та ринковою вартістю. Результати узгоджуються з минулими дослідженнями, де фірми з високою репутацію мають високу ринкову вартість

Deep Learning Aided Parametric Channel Covariance Matrix Estimation for Millimeter Wave Hybrid Massive MIMO

Millimeter-wave (mmWave) channels, which occupy frequency ranges much higher than those being used in previous wireless communications systems, are utilized to meet the increased throughput requirements that come with 5G communications. The high levels of attenuation experienced by electromagnetic waves in these frequencies causes MIMO channels to have high spatial correlation. To attain desirable error performances, systems require knowledge about the channel correlations. In this thesis, a deep neural network aided method is proposed for the parametric estimation of the channel covariance matrix (CCM), which contains information regarding the channel correlations. When compared to some methods found in the literature, the proposed method yields satisfactory performance in terms of both computational complexity and channel estimation errors.Comment: M.Sc.

Violence among the Youth in Turkey: An Assessment of General Strain Theory

Most tests of criminological theories have been carried out in the western world, especially the United States. Agnew developed a General Strain Theory and claimed that it could account for deviance/crime in the developing countries. However, the support for the theory was generally mixed at best. The goal of this study is to examine the major theses of general strain theory in relation to youth violence in Nigde, a small city in central part of Turkey. The data came from a random sample of 974 students drawn from the lists of the university students at Nigde University (N= 12,514). Data were analyzed by using logistic regression analysis. The present study focused on three important research questions: Is the influence of strain on violence positive, Is the impact of strain on violence is mediated by anger, and Is the effect of strain on violence moderated by some criminal and non-criminal copings? The results indicated that few strain variables had direct positive impacts on violence. Anger had positive effect on the dependent variable. Few interactions between the strain and coping variables were observed. In short, the overall results gave a limited support for the three major arguments of general strain theory

Determination of the effects of soil moisture during treatment and different irrigation timing after treatment on he performance of soil herbicides

Bu çalışmada, Fluometuron ve Fluchloridone etkili maddesine sahip iki toprak herbisitinin performansına uygulama sırasındaki toprak nemi ve uygulama sonrasında farklı zamanlarda yapılan sulamanın etkisini belirlemek amaçlanmıştır. Çalışmanın ilk aşamasında diğer aşamalarda kullanılacak dozu belirlemek amacı ile her iki herbisit için doz-etki denemeleri yapılmıştır. Yapılan doz etki denemeleri sonucunda ED50 ve ED90 değerleri olarak Fluometuron için sırasıyla 62,5 ml/da ve 125 ml/da; Fluchloridone için 50 ml/da ve 100 ml/da dozları seçilmiştir. Çalışmanın ikinci aşamasında farklı nem düzeylerindeki toprağa yukarıda belirtilen dozlar uygulanmış ve herbisitlerin Amaranthus retroflexus L. (Horozibiği) ve Portulaca oleracea L. (Semizotu) üzerine olan etkileri belirlenmiştir. Bu çalışmanın sonuçları denemeye, doza ve yabancı ota bağlı olarak değişim göstermekle birlikte, genel olarak; herbisit uygulaması sırasında toprak neminin yüksek olması ile birlikte herbisitin etkisi de artmıştır. Yine ikinci aşamada kuru toprağa herbisit uygulamaları yapılmış ve sonrasında farklı zamanlarda sulama yapılarak sulama zamanının herbisitlerin performansı üzerine olan etkisi belirlenmiştir. Sonuç olarak her iki herbisit içinde en düşük etki herbisit uygulamasından 14. gün ve sonrasında, en yüksek etki ise uygulamadan 1-7 gün sonra sulama yapılmasıyla elde edilmiştir, bu durum özellikle herbisitlerin ED50 dozlarında açıkça görülmüştür. Çalışmanın sonuçları uygulama esnasındaki toprak neminden ziyade ilaçlama sonrasındaki sulamanın herbisit etkinliği açısından daha önemli olduğuna işaret etmektedir.The aim of this study was to investigate the effects of soil moisture during treatment and different irrigation timing after treatment on the performance of two soil herbicides with fluometuron and flurochloridone active ingredients. Dose-response experiments were carried out at the first step to determine the ED50 and ED90 doses of both herbicides in order to use discriminate doses for further studies. As the result ED50 and ED90 doses of Fluometuron were determined as 62,5 and 125 ml/da, respectively, while 50 and 100 ml/da doses were determined for Flurochloridone. At the second step of the study these doses were applied to soils with different moisture levels and the effect of herbicides were assessed on Amaranthus retroflexus L. (Redroot pigweed) and Portulaca oleracea L. (Common purslane). Although results of these studies were variable depending on the experiment, dose and weed species, it has been generally observed that the herbicide effect was higher as with increasing soil moisture. Also at the second step herbicides were applied to dry soils and then irrigated at different timings after treatment, in order to evaluate the effect of irrigation timing after treatment on herbicide efficacy. As the result lowest effects of both herbicides were obtained with irrigations done after 14 days and later, while highest efficacy was obtained when irrigations were done 1-7 days after treatment, this case was especially observed with ED50 doses of herbicides. Results of these studies revealed that irrigation after treatment is more important for herbicide efficacy than soil moisture during herbicide treatment

The representation of emperor as God in Byzantine mosaics and frescos

The present paper focuses on the representation of Byzantine emperor as deity in the mosaics and frescos. Though there were many hesitations concerning the representation of divinity in visual images, it was considered that the figural art was able to express the sacred. Much interest was given to human body, which after the initial consideration as the locus of corruption, becomes gradually considered as the instrument reaching the divine dimension. The tangible piety gradually is regarded as a vehicle for the disclosure of the divine. As Byzantine emperor was considered to be a correspondent of divinity on earth, the artists who aim at representing a sacred dimension develop some techniques and elaborate some motifs that will reveal the emperor as holding and transmitting the transcendental. © 2015, Mediterranean Center of Social and Educational Research.

Comparative Analysis of Dictionary versus Corpus Use in Translation Teaching for Non-Translation English Majors

The purpose of this research which employs qualitative and quantitative research methodologies is to investigate the perceptions developed by non-translation students in a tertiary level EFL setting to the use of corpus versus dictionary as two translation tools after twelve weeks of explicit instruction. The samples of the study are from the English Department of a middle sized university in the Eastern Black Sea region in Turkey. For this purpose, a qualitative research methodology was used in the study and the data was obtained through questionnaires and open-ended interviews with 55 non-translation students in a tertiary level EFL setting. The samples were delivered the questionnaires and interviews and descriptive analysis technique was used in order to analyse the findings.  In the study, the perceptions of the tertiary level EFL non-translation students towards the use of dictionary versus corpus in their translation practices were investigated. The possible potential benefits of using corpus as an alternative tool in the students’ translation practices were the subjects of further inquiry in the study. The results revealed that most non-translation students preferred to use dictionaries in their translation practices and few others considered corpus as an alternative tool while translating. A considerable number of students, on the other hand, expressed their concerns for the corpus use in translation as well as others reported limited exposure to corpus use, and for which reason they preferred to use dictionaries in their translation practices. Keywords: Perception, Translation, Corpus, Dictionary.

Machine learning algorithms for fluid mechanics

Neural networks have become increasingly popular in the field of fluid dynamics due to their ability to model complex, high-dimensional flow phenomena. Their flexibility in approximating continuous functions without any preconceived notion of functional form makes them a suitable tool for studying fluid dynamics. The main uses of neural networks in fluid dynamics include turbulence modelling, flow control, prediction of flow fields, and accelerating high-fidelity simulations. This thesis focuses on the latter two applications of neural networks. First, the application of a convolutional neural network (CNN) to accelerate the solution of the Poisson equation step in the pressure projection method for incompressible fluid flows is investigated. The CNN learns to approximate the Poisson equation solution at a lower computational cost than traditional iterative solvers, enabling faster simulations of fluid flows. Results show that the CNN approach is accurate and efficient, achieving significant speedup in the Taylor-Green Vortex problem. Next, predicting flow fields past arbitrarily-shaped bluff bodies from point sensor and plane velocity measurements using neural networks is focused on. A novel conformal-mapping-aided method is devised to embed geometry invariance for the outputs of the neural networks, which is shown to be critical for achieving good performance for flow datasets incorporating a diverse range of geometries. Results show that the proposed methods can accurately predict the flow field, demonstrating excellent agreement with simulation data. Moreover, the flow field predictions can be used to accurately predict lift and drag coefficients, making these methods useful for optimizing the shape of bluff bodies for specific applications.Open Acces
