Faaliyet Raporlarında Metin Sıralamasının Profesyonel Olmayan Yatırımcı Kararlarına Etkisi Üzerine Bir Araştırma

Profesyonel olmayan yatırımcıların karar alma sürecinde, faaliyet raporlarındaki metin sıralaması ile grafiklerin bulunmasının bir etkisinin olup olmadığını tespit etmeyi amaçlayan araştırmada anket yöntemi uygulanmış olup, 422 öğrenciden örneklem üzerinde çalışma yürütülmüştür. Araştırmanın evrenini Süleyman Demirel Üniversitesi İİBF öğrencileri oluşturmaktadır. Anket kapsamına SDÜ’de eğitim görüp üçüncü ve dördüncü sınıfa devam eden İşletme, Bankacılık ve Finans, İktisat ve Maliye bölümleri başta olmak üzere diğer bölüm ve lisansüstü öğrencileri de dâhil edilmiştir. Çalışmada, Borsa İstanbul’da işlem gören bir market zinciri şirketine ait 2018 yılı faaliyet raporunu kullanılmıştır. Sonuçların istatistiki anlamlılığını test etmek için Mann- Whitney U Test kullanılmıştır.Araştırmada bilgi aktarımında planlı sunum sıralanmasından dolayı, profesyonel olmayan yatırımcıların yenilik etkisine duyarlı oldukları sonucuna varılmıştır. Başka bir ifade ile yatırımcının, faaliyet raporlarında olumlu bilgilerin ve gelişmelerin raporun sonunda olduğunda, şirkete bakış açısı olumlu olmaktadır, bu sonuç olumsuz bilgiler için de geçerlidir. Olumsuz bilgilerden hemen sonra olumlu bir grafiğin sunulması, yatırımcının kararı üzerinde neredeyse hiçbir etkiye sahip olmadığı sonucuna varılmıştır. Genel olarak, yenilik etkisi, İİBF öğrencileri ve özellikle Maliye bölümünde ortaya çıkmıştır ve İİBF öğrencisi olmayan kontrol grubunda bu etki bulunmamıştır. Tüm öğrencilerin sonuçları; bilgi sunum sıralanmasının yatırım kararını etkilemezken, yatırım miktarı ile gelir beklentisi üzerinde bir etkisi bulunmuştur. Bütün olarak (Bankacılık ve Finans, İşletme, İktisat ve Maliye) bölümlerin sonuçları; bilgi sunum sıralanmasının yatırım kararı, yatırım miktarı, gelir beklentisi ile şirketin değerlendirilmesini etkilemiştir. İİBF diğer bölümlerde okuyan öğrencilerin durumunda, yatırım kararına ilişkin öncelik etkisi bulunmuştur. Bulunan yenilik etkisi, erkek ve finansal okuryazarlık düzeyi yüksek olan öğrencilerin kararlarında bulunmayıp sadece kadın ve finansal okuryazarlık düzeyi düşük olan öğrenciler kararlarında bulunmuştur.Faaliyet raporların hazırlama sürecinde; bu raporun içerdiği bilgilerin doğru olması ile istatistiki verilerin ve analizlerin sade ve açık olması dikkat edilmesi gereken hususların başındadır. Ancak, araştırmada ulaşılan bulgular, bilgilerde bir değişiklik olmadığı halde, bilgi sunum sıralanmasında yapılan değişikliklerin profesyonel olmayan yatırımcının kararını, şirketin lehine etkileyebileceğini göstermektedir. Ayrıca, sonuçlar bu tür belgelerin üzerindeki uygulanan denetim işlemlerinin güçlendirilmesinin gerekliliğini göstermektedir

Resistance Rates of Mycobacterium Tuberculosis Complex Isolates Obtained From Clinical Samples to Major Antituberculous Drugs: a Study in Edirne, Turkey

DergiPark: 439208tmsjAims: The aim of this study is to reveal the rates of the Mycobacterium tuberculosis complex resistance to major antituberculous drugs (streptomycin, isoniazid, rifampicin, ethambutol) by the evaluation of the specimens that are sent to Trakya University Hospital Microbiology Laboratory. Methods:In this study, laboratory data of the cases that were pre-diagnosed with tuberculosis between 11/02/2016 and 31/12/2017 were scanned retrospectively. To compare the annual data descriptive statistics as arithmetic mean, numbers and percentages were used. Results: Out of 4752 samples, 133 (2.79%) were culture positive. 120 isolates were identified as Mycobacterium tuberculosis complex, while other 13 were defined as Mycobacterium other than tuberculosis. Antimycobacterial susceptibility tests showed that 9 (7.5%) isolates were resistant to streptomycin, 10 (8.33%) isolates to isoniazid, 4 (3.33%) isolates to rifampicin, 4 (3.33) isolates to ethambutol. 5 (4.16%) isolates were multidrug resistant. Conclusion: Antituberculous drug resistance is still a threat for an effective treatment of tuberculosis and streptomycin resistance has increased. However, it is also pointed out that presence of Mycobacterium other than tuberculosis in isolates has increase

Short-term Postoperative Outcomes of Platelet-rich Plasma after Inferior Turbinate Radiofrequency

Introduction:To evaluate the effect of submucosal platelet-rich plasma (PRP) therapy on intraoperative bleeding and early postoperative pain and crusting in patients undergoing inferior turbinate radiofrequency.Methods:A total of 70 adult patients with isolated inferior turbinate hypertrophy were included in this prospective study and randomized to the PRP or control groups. PRP was prepared for all patients. After applying submucosal radiofrequency to the inferior turbinates under local anesthesia, submucosal PRP was injected into the study group, and submucosal saline was injected into the control group. Patient controls were performed by another specialist. The patients and the specialist who performed the controls were blinded to which group they were in. All patients were evaluated endoscopically 1, 7, and 21 days after the operation.Results:The mean age of the patients was 33.37±11.92 years (range: 18 to 54). The two groups had no significant differences in intraoperative bleeding and mucociliary clearance values (p>0.05). The amount of crusting and the visual analog scale pain values were significantly lower in the submucosal PRP -injected group (p<0.05).Conclusion:Submucosal injection of PRP after radiofrequency of the inferior turbinate reduces nasal obstruction and pain due to crusting. With these features, it can be concluded that this procedure accelerates recovery and increases patient comfort in the early postoperative period

Do the Age of Implantation, the Widths of Internal Acoustic Canal and Bony Cochlear Nerve Canal Affect the Auditory Performance of Primary School Children with Bilateral Cochlear Implants?

Objective:To reveal the correlation between implantation age, the internal acoustic canal (IAC) width, bony cochlear nerve canal (BCNC) width, and auditory performance in primary school children with bilateral cochlear implantation (CI).Methods:Preoperative IAC and BCNC widths of 57 pre-lingually deaf children aged 7–11 years who had previously undergone bilateral CI in our institution were reviewed and cut-off values were calculated. Twenty-four patients who had additional problems and could not attend school and those who refused to participate in the study were excluded. The remaining 33 were invited to the hospital, and their speech perception tests, and language development scores were analyzed (16 of 33 patients had been operated on before the age of 24 months).Results:The cut-off values calculated from the 114 ears of 57 patients were 3.86 mm for IAC width and 1.56 mm for BCNC width. The auditory performances of the 33 patients after CI were not significantly different in the narrow and normal width groups. However, speech perception test results, and language development scores of patients implanted before the age of 24 months were significantly higher.Conclusion:There are some studies showing that children with bilateral sensorineural hearing loss have narrower IAC and BCNC widths. However, we concluded that the widths of the IAC and the bone cochlear nerve canal did not affect auditory performance. We found that implantation age is the single most important determinant of speech-language development after CI

Magnetic Resonance Imaging Findings of Suprapatellar Fat Pad Impingement Syndrome: A Retrospective Study

Objective: Peripatellar fat pads are extrasynovial intracapsular fat tissues. Suprapatellar, perifemoral, and infrapatellar (Hoffa fat pad) fat pads are included in the peripatellar fat pad. This study aimed to describe the magnetic resonance imaging (MRI) signs of suprapatellar fat pad impingement syndrome, describe their prevalence and pattern, and look into the relationship between their MRI and clinical signs. Methods: Two radiologists retrospectively analyzed 5,700 patients’ knee MRI data between December 2010 and December 2015. We documented the MRI findings that were associated with suprapatellar fad pad impingement syndrome. The correlations between age, osteoarthritis, chondromalacia, and the patellofemoral joint were evaluated using Pearson’s correlations. Results: In our study group, the prevalence of suprapatellar fat pad impingement was 5.3%. Of the patients 52% were men and 48% were women. Patients who were admitted to the clinic complained of non-specific pain in 80.3% of patients. Twenty-seven patients (8.9%) presented with isolated suprapatellar impingement syndrome; 185 (60.9%) showed an increase in intra-articular fluid; 4 (1.3%) had synovitis findings; 17 (5.6%) had medial collateral ligament tears; 107 (35.2%) had quadriceps femoris tendinitis; 8 (2.6%) had patellar tendinitis; 80 (26.3%) had a medial meniscus tear; 23 (7.6%) had Baker’s cyst; and 30 (9.9%) had soft-tissue edema. Medial meniscus degeneration was observed in 51 (16.8%) patients, Hoffa edema was observed in 31 (10.2%) patients, and anterior cruciate ligament tears in 3 (1%) patients. There were positive correlations between age and osteoarthritis (r=0.4660, p<0.05), between chondromalacia and the grade of the chondromalacia (r=0.5198, p<0.05), and between lateral subluxation and lateral tilt as opposed to the normal patellofemoral relationship (r=0.3171, p<0.05).in patients with suprapatellar fat pad impingement. Conclusion: The most common symptom of suprapatellar impingement, that is one of the major causes of anterior knee pain, is non-specific pain. The most common additional MRI findings are increased intra-articular fluid and quadriceps femoris tendinitis

Spatial relation learning in complementary scenarios with deep neural networks

A cognitive agent performing in the real world needs to learn relevant concepts about its environment (e.g., objects, color, and shapes) and react accordingly. In addition to learning the concepts, it needs to learn relations between the concepts, in particular spatial relations between objects. In this paper, we propose three approaches that allow a cognitive agent to learn spatial relations. First, using an embodied model, the agent learns to reach toward an object based on simple instructions involving left-right relations. Since the level of realism and its complexity does not permit large-scale and diverse experiences in this approach, we devise as a second approach a simple visual dataset for geometric feature learning and show that recent reasoning models can learn directional relations in different frames of reference. Yet, embodied and simple simulation approaches together still do not provide sufficient experiences. To close this gap, we thirdly propose utilizing knowledge bases for disembodied spatial relation reasoning. Since the three approaches (i.e., embodied learning, learning from simple visual data, and use of knowledge bases) are complementary, we conceptualize a cognitive architecture that combines these approaches in the context of spatial relation learning

Congenital arterial thrombosis in newborn: A case report

Neonatal thrombosis is a serious event that can cause mortality or severe morbidity. Although catheters are the most common cause of neonatal thrombosis, spontaneous events can also occur. Arterial thrombosis is very rare and accounts for approximately half of all thrombotic events in neonates. Genetic prothrombotic risk factors may affect the occurence of neonatal thrombosis. In this report, a case of left brachial, radial, and ulnar arterial thrombosis associated with methylene-tetrahydrofolate reductase (MTHFR) gene C677T and A1298C polymorphism heterozygosity is presented. Plasma homocysteine level and other prothrombotic components were normal. Standard heparin, aspirin, vitamin B12, B6 and folic acid were initiated for treatment. However, the left arm of the patient was amputated at the shoulder because its capillary stream could not be observed. We suggest that MTHFR gene C677T and A1298C polymorphism heterozygosity might be investigated in neonates with congenital arterial thrombosis in spite of normal serum homocysteine levels. © Trakya University Faculty of Medicine

Decreased heart rate recovery may predict a high SYNTAX score in patients with stable coronary artery disease

An impaired heart rate recovery (HRR) has been associated with increased risk of cardiovascular events, cardiovascular, and all‐cause mortality. However, the diagnostic ability of HRR for the presence and severity of coronary artery disease (CAD) has not been clearly elucidated. Our aim was to investigate the relationship between HRR and the SYNTAX (SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery) score in patients with stable CAD (SCAD). A total of 406 patients with an abnormal treadmill exercise test and ≥50% coronary stenosis on coronary angiography were included. The HRR was calculated by subtracting the HR in the first minute of the recovery period from the maximum HR during exercise. The SYNTAX score ≥23 was accepted as high. Correlation of HRR with SYNTAX score and independent predictors of high SYNTAX score were determined. A high SYNTAX score was present in 172 (42%) patients. Mean HRR was lower in patients with a high SYNTAX score (9.8 ± 4.5 vs. 21.3 ± 9, p < 0.001). The SYNTAX score was negatively correlated with HRR (r: -0.580, p < 0.001). In multivariate logistic regression analysis, peripheral arterial disease (OR: 13.3; 95% CI: 3.120–34.520; p < 0.001), decreased HRR (OR: 0.780; 95% CI: 0.674–0.902; p = 0.001), peak systolic blood pressure (OR: 1.054; 95% CI: 1.023–1.087; p = 0.001), and peak HR (OR: 0.950; 95% CI: 0.923–0.977; p < 0.001) were found to be independent predictors of a high SYNTAX score. Our results showed that HRR is significantly correlated with the SYNTAX score, and a decreased HRR is an independent predictor of a high SYNTAX score in patients with SCAD

Who Sets the Agenda? Analyzing Key Actors and Dynamics of Economic Diversification in Kazakhstan Throughout 2011–2016

This contribution attempts to answer the key question: Who sets the agenda for economic diversification in the context of Kazakhstan? This question remains critical in current scholarly debates. Although Kazakhstan, a young post-Soviet developing nation, has received fair scholarly attention with regard to the agenda setting stage of the policy cycle, the existing literature has yet failed to (1) empirically establish who actually sets the agenda for a certain policy issue and (2) employ the Internet research methods. This paper seeks to fill these gaps. The literature review of Kazakh-specific agenda setting publications suggests that among the major actors, the government tends to exert predominant influence, though other actors may also play a role, for example, media and academia. This research is driven by Internet penetration rate data and focuses on the period from January 2011 until December 2016. The findings lead to two key conclusions. First, think tanks seem to set the government agenda for economic diversification policy in Kazakhstan. Second, the government, while exhibiting the larger agenda setting magnitude vis-à-vis the other actors, shapes the subsequent debates as measured by the number of relevant references in media, think tanks, and academic publications. This research seeks to contribute to existing agenda setting theories in the Internet era by defining the most important actor(s), specifically in the Kazakh context based on longitudinal dynamics in attention
