Yayın Construction of a Turkish proposition bank(Tubitak Scientific & Technical Research Council Turkey, 2018) Ak, Koray; Toprak, Cansu; Esgel, Volkan; Yıldız, Olcay TanerThis paper describes our approach to developing the Turkish PropBank by adopting the semantic role-labeling guidelines of the original PropBank and using the translation of the English Penn-TreeBank as a resource. We discuss the semantic annotation process of the PropBank and language-specific cases for Turkish, the tools we have developed for annotation, and quality control for multiuser annotation. In the current phase of the project, more than 9500 sentences are semantically analyzed and predicate-argument information is extracted for 1330 verbs and 1914 verb senses. Our plan is to annotate 17,000 sentences by the end of 2017.Yayın Psychometric properties of the pathological buying screener: reliability and validity study(Kare Publishing, 2021-06) Dikbaş, Ganime Tuba; Acartürk, Ceren; Akyunus, MirayObjective: The Pathological Buying Screener (PBS) is a self-report scale used to evaluate compulsive buying behavior. The aim of this study was to assess the validity and reliability of a Turkish version of the PBS in a nonclinical sample. Method: A total of 457 adult participants aged 18-64 years were enrolled in this study. Internal consistency, test-retest reliability and structure, concurrent and criterion-related predictive validity analyses were conducted to ensure reliability and validity for use of the scale with a Turkish population. As part of the validity study, all of the participants were asked to complete a battery of self-report scales: the Compulsive Buying Scale, the Brief Symptom Inventory, the Rosenberg Self-Esteem Scale, the Barratt Impulsiveness Scale-Short Form, and the PBS. In order to examine the test-retest reliability, 75 participants were asked to complete the questionnaire once again 2 weeks after the first administration. Results: The results of this study revealed that the PBS had good internal consistency and test-retest reliability. The findings supported concurrent and criterion-related predictive validity, and a 2-factor structure, consistent with the original form. Conclusion: The Turkish version of the PBS is a valid and reliable measurement tool that will add to understanding of pathological buying behavior.Yayın A path loss model for link budget analysis of indoor visible light communications(Istanbul Univ-Cerrahpasa, 2021-05) Miramirkhani, FarshadIn the context of beyond 5G indoor communication systems, visible light communications (VLC) has emerged as a viable supplement for existing radio frequency based systems and as an enabler for high data rate communications. However, the existing indoor VLC systems are limited by detrimental outages caused by fluctuations in the VLC channel gain because of user mobility. In this study, we proposed a tractable path loss model for indoor VLC that reflects the effect of room size and coating material of surfaces. We performed an extensive advanced ray tracing simulation to obtain the channel impulse responses within a room and presented a path loss model as a function of distance, room size, and coating material through curve fitting. In addition, path loss parameters such as the path loss exponent and the standard deviation of the shadowing component were determined. The simulation results indicate that path loss is a linear function of distance, path loss exponent is a function of room size and coating material, and shadowing follows a log normal distribution.Yayın A new subspecies of Phoenix theophrasti Greuter (Phoenix theophrasti Greuter subsp. golkoyana Boydak) from Turkey(Istanbul Univ-Cerrahpasa, 2019-07) Boydak, MelihIn the present study, a new subspecies (Phoenix theophrasti Greuter subsp. golkoyana Boydak) is described in Turkey. The unidentified Phoenix taxon native to Bodrum-Golkoy, Aegean Turkey and named as the "Golkoy Phoenix population" has been known to Golkoy's inhabitants for centuries. The Golkoy Phoenix population was considered to be representative of P. theophrasti. Boydak made the first of a number of trips to Golkoy and immediately noticed some distinct differences between the Golkoy Phoenix population, P. theophrasti Greuter, and Phoenix dactylifera L in the early summer of 1990. He continued his investigations on this taxon for many years to shed light on the subject. He made two new trips to the three native stands of P. theophrasti and the Golkoy Phoenix populations in 2015 and 2018. Measurements and observations were made on the morphological characteristics that showed distinct differences among the Golkoy Phoenix population, P. theophrasti, and P. dactylifera. These were related to the length of male stalks and female inflorescences and some fruit and seed characteristics. The results indicate that some distinctive morphological characteristics of the "Golkoy Phoenix population" merit its being described as a new subspecies. "Phoenix theophrasti Greuter subsp. golkoyana Boydak" differs from P. theophrasti Greuter with respect to its longer fruiting-female stalk length and longer male stalk length, its fruiting stalks hold fruits marginally higher, and its having seeds with slightly visible striate surface crust structures and deeper-wider grooves.Yayın The statistics of energy states of a Hookean model for proteins(TÜBİTAK, 2000) Erzan, Ayşe; Tüzel, ErkanA generic model of a random polypeptide chain, with discrete torsional degrees of freedom and Hookean springs connecting pairs of hydrophobia residues, reproduces the energy probability distribution of real proteins over a very large range of energies. We show that this system with harmonic interactions, under dissipative dynamics driven by random noise, leads to a distribution of energy states obeying a modified one-dimensional Ornstein-Uhlenbeck process with reflecting boundary conditions, and giving rise to distributions of the Wigner or inverse Gaussian form. A continuum approximation leads to a path integral formulation of the problem.Yayın Attentional bias and training in social anxiety disorder(Turkish Neuropsychiatric Society, 2015-03) Fıstıkçı, Nurhan; Saatçioğlu, İbrahim Ömer; Keyvan, Ali; Topçuoǧlu, VolkanCognitive behavioral therapy (CBT) is one of the most effective treatment modalities for social anxiety disorder (SAD), showing a high level of clinical evidence supporting its effectiveness. On the other hand, lack of the desired benefit from this treatment in some patients causes continuation of the search for new techniques. Recent research studies have focused on attentional bias and attention training in SAD. Attention processes in SAD have been a major target of interest and investigation since the introduction of the first cognitive models explaining SAD. In the first model, it was highlighted that attention was self-focused. The relationship between threatening stimuli and attention was considered in the subsequent models. Attentional bias towards threat may take place in several ways, such as facilitated processing of threat, difficulty in disengaging attention from the threat and avoidance of attention from the threat. After these descriptions regarding the phenomenology of the disorder, treatments to modify attention, processes were developed. In spite of conflicting results, investigations on attentional training are promising. Attention processes, attentional bias and attentional training in SAD are discussed in this review.Yayın The effect of mad cow (BSE) scare on beef demand and sales loss: The case of Izmir(Scientific Technical Research Council Turkey-Tubitak, 2005) Miran, Bülent; Akgüngör, Emine SedefThis paper investigates the effect of the BSE scare on beef consumption due to the intense media coverage. Using monthly data, a beef demand model for January 1995-February 1997 period is estimated for Izmir Province. Beef sales dropped immediately after the media coverage on BSE in April 1996 and continued through June 1996 when the intense media coverage stopped. The econometric model reveals that beef sales in Izmir would have been 36.4 % higher if the BSE crisis never occurred. The annual individual willingness to pay is $0.5224 per year to avoid consuming BSE contaminated meat.Yayın Olanzapin kullanımına bağlı çekilme diskinezisi ve süpersensitivite psikozu(Turkish Neuropsychiatric Society, 2016-06) Karaş, Hakan; Güdük, Mehmet; Saatçioğlu, İbrahim ÖmerTardive dyskinesia (TD) usually appears after years of antipsychotic drug use and appears to be related to the total lifetime medication dose. In withdrawal-emergent dyskinesia (WE-D), which is considered to be a subtype of TD, dyskinetic symptoms often appear shortly after a rapid reduction in antipsychotic drug dose or sudden discontinuation of the drug. Supersensitivity psychosis, which is frequently observed along with TD and is considered to have a similar etiology as TD, is a psychotic relapse phenomenon that occurs after the withdrawal of an antipsychotic drug or a rapid reduction in the drug dosage. In general, atypical antipsychotics tend to be associated with less propensity to cause TD when compared with typical antipsychotics. Furthermore, olanzapine and clozapine may have a therapeutic potential in improving or totally curing TD. In this study, a case of WE-D because of discontinuing olanzapine use and supersensitivity psychosis is discussed.Yayın One size does not fit all in psychotherapy: Understanding depression among patients of Turkish origin in Europe(Turkish Neuropsychiatric Society, 2016-03) Balkır Neftçi, Nazlı; Barnow, SvenOver the last decades, Europe has become an immigration country hosting an estimated 56 million international immigrants. Yet, a large amount of literature suggests that migration is associated with a higher risk of common mental disorders, such as depression and anxiety. As representatives of one of the largest immigrant groups in Europe, various studies have shown that Turkish immigrants exhibit a higher prevalence of depression and anxiety disorders than do the background population. Nevertheless, it is also well demonstrated that this particular patient group is more likely to terminate treatment prematurely and displays lower rates of treatment compliance than their native counterparts. This reluctance for service utilization might be partially because of the fact that people from non-Western ethnocultural backgrounds (e.g., Turkey) often have a different notion and comprehension of mental health and illness as compared with those of the people from Western societies. Such mismatch often results in discrepancies between the needs and expectations of immigrant patients and clinicians, which attenuate the communication and effectiveness of treatment and lead to unexplained high dropout rates. To provide continued provision of culture-sensitive, high quality, evidence-based mental health care, the advancement of researches exploring such sociocultural differences between the patients’ and the clinicians’ notions of mental health must occur. In response to these problems, the current review aims to explore the interplay between culture and mental processes that associate with the etiology, maintenance, and management of depression among Turkish immigrant patients. This is to inform clinicians regarding culturespecific correlates of depression among Turkish patients to enable them to present interventions that fit the needs and expectations of this particular patient group.Yayın A tree-based approach for English-to-Turkish translation(Tubitak Scientific & Technical Research Council Turkey, 2019) Bakay, Özge; Avar, Begüm; Yıldız, Olcay TanerIn this paper, we present our English-to-Turkish translation methodology, which adopts a tree-based approach. Our approach relies on tree analysis and the application of structural modification rules to get the target side (Turkish) trees from source side (English) ones. We also use morphological analysis to get candidate root words and apply tree-based rules to obtain the agglutinated target words. Compared to earlier work on English-to-Turkish translation using phrase-based models, we have been able to obtain higher BLEU scores in our current study. Our syntactic subtree permutation strategy, combined with a word replacement algorithm, provides a 67% relative improvement from a baseline 12.8 to 21.4 BLEU, all averaged over 10-fold cross-validation. As future work, improvements in choosing the correct senses and structural rules are needed.
