Three essays in applied econometrics
No full textThis dissertation presents three essays which are linked by the use of econometric models to explain problems that are only explained descriptively in the literature. The first essay, statistically shows that a systematic measurement bias can significantly distort predictions obtained using an international accounting framework due to the sizable diversity of the parties involved in it. Once the measurement bias is taken into account, the average value gains on the US foreign asset and liability categories are estimated to be smaller, and no evidence is found on positive yield differential. The second essay estimates the value gains and the mismeasurement using data at multiple frequencies. The results show that positive sizable return differential is present after 2002. The third essay shows that the increasing availability of prescription opioids threatens sellers' profit margin since it is a close substitute for heroin and forces sellers to find alternative methods to compensate buyers in the case of a negative supply shock.Ph.D.Includes bibliographical referencesIncludes vitaby Emel Oylum Yildiri
Marmara University Medical Students' Perception on Sexual Violence against Women and Induced Abortion in Turkey
No full textBackground: Historically, sexual assault is a common issue in Turkey. As doctors are one of the steps to help sexually assaulted women, medical students should have basic knowledge of and sensitivity regarding this subject. Another common women's public health issue is induced abortion. In countries where access to abortion is restricted, there is a tendency towards unhealthy abortion. Aims: The aims of this study are: (1) to determine the attitudes and opinions of Marmara University Medical Faculty students about sexual assault against women and induced abortion and (2) to propose an educational program for medical students about sexual assault and abortion. Study Design: Cross-sectional study. Methods: The questionnaires were self-administered and the data were analyzed using SPSS v. 15.0. First, the descriptive statistics were analyzed, followed by Chisquare for contingency tests assessing differences in attitudes toward sexual assault and induced abortion by factors such as gender and educational term. Differences were considered statistically significant at p<0.05. Results: About 89.6% of the participants (n=266) reported that they had never been sexually assaulted and about 11.5% of the women (n=19) had been sexually assaulted. There was no significant relationship between previous sexual assault and gender (p>0.05). Although there was no significant difference regarding the extent of punishment by victim's status as a virgin, 21.3% (n=63) agreed that punishment should be more severe when the victim was a virgin. About 40.7% (n=120) agreed that the legal period of abortion in Turkey (10 weeks) should be longer. The majority (86.1%, n=255) agreed that legally prohibiting abortions causes an increase in unhealthy abortions. Conclusion: An educational program on these issues should be developed for medical students

As a result of the research, it was determined that there was a significant positive correlation between children's perspective taking and receptive and expressive language ability scores. Moreover, it has been determined that this relationship begins as early as three years of age. Finally, it has also been determined that language ability significantly predicts children's ability to take perspective
Assessment of implication of competitiveness on human development of countries through data envelopment analysis and cluster analysis
No full textFüsun Ülengin (Dogus Author) -- Özgür Kabak (Dogus Author) -- Şule Önsel (Dogus Author) -- Emel Aktaş (Dogus Author)Globalization speeds up competition among nations in various sectors. In terms of multinational and transnational phenomena, countries are seen as inescapable from competition, thus the linking of the term global with "competitiveness." The research described here explores the relationship between the competitiveness of a country and its implications for human development. For this purpose, using data envelopment analysis (DEA) and cluster analysis, 44 selected countries were evaluated. An output-oriented super-efficiency model where global competitiveness indicators are taken as input variables with human development indicators as output variables is utilized. Then cluster analysis depending on the competitiveness and human development indicators is conducted by using self-organizing maps to specify the development levels of the countries. Both analyses are repeated for years between 2005 and 2007. Finally, the relationship between the super efficiency scores and the development levels is analyzed

The Analysis of Conceptual Studies On Contemporary Ceramics Art in Light of Peter Osborne's Conceptual Art Initiative
No full textSanat olgusu ortaya çıktığı dönemden günümüze değin yapılan pek çok sanat eseriyle farklı nitelik ve yorumlar kazanarak gelişmiştir. Bu gelişmeler ve dönüşümler sonucunda 20.yüzyılın ikinci yarısından itibaren içerisinde bulunduğumuz dönem postmodern olarak adlandırılmakta ve sanatın sonu şeklinde değerlendirilmektedir.Sanatta yaşanan bu büyük dönüşümler pek çok disiplini olduğu gibi seramik sanatını da etkilemiştir. Seramik sanatı 19.yüzyıl ve sonrası sanayi devriminden sonra gelişen teknoloji ve farklılaşan kültürel yapılarla, 20.yüzyılda sanatsal bir disiplin olarak kabul görmüştür. Bu süreçte çağdaş seramik sanatçılarının yorumlarıyla, kavrama yönelik eserler ortaya konmuştur.Kavramsal Sanat ise temelinde düşüncenin yapıta üstünlüğü fikrini barındıran Postmodern dönem içerisinde büyük bir kırılma yaratmış olan bir eğilimdir. Kavramsal sanat, seramik sanatının evrensel nitelik kazanmasına, geleneksel ve modernist uslüba karşı duran kavramsal seramik eserler üretilmesine olanak sağlaması bakımından seramik sanat tarihinde önemli bir yere sahiptir. Postmodernizmin eklektik yapısıyla birleşen kavramsal seramik eserler çağın gerçekliklerinin kavranmasını kolaylaştırırken, geçmişle bağ kurarak belgesel bir nitelik taşımaktadır. Bu çalışmada, çağdaş seramik sanatında, sanat anlayışında bir dönüm noktası olan kavramsal sanatın önemi ve seramik sanatına katkıları felsefe profesörü ve yazar Peter Osborne'nin kavramsal sanat açılımı doğrultusunda incelenmektedir.Ever since it emerged to present, the art fact has developed by getting different qualities and comments with many art works. As a result of these developments and transformations, the period which we are in since the second half of the 20th century is called Postmodernism and considered to be end of the art These efficient transformations as influenced the ceramic art as many disciplines. In the 20th century, ceramic art has been accepted as an artistic discipline with the 19th century and later by industrial revolution, the developing of technology and differing cultural structures. In this process, conceptual art works were created by contemporary ceramic artists' interpretations. Conceptual art is a trend which created a big break in the postmodern period, which is based on the idea that is thought, has superiority to the art work. In the ceramic art history, conceptual art history has an important place because of enabling of the creating ceramic art works which stands against the traditional and the modernist style. Conceptual ceramic art works, which combine with eclectic nature of postmodernism, has a documentary feature by establishing a link with the past while make it easy to grasp realities of era. In this study, the importance of conception art, which is a milestone in the art conception and its contributions to ceramic art, are examined according to philosophy professor and author Peter Osborne's conceptual art initiative
Breastfeeding self-efficacy of mothers and relationship with depression risk
No full textAnnenin bebeğine sağlıklı bir şekilde bakabilmesi ve uzun dönem emzirebilmesi için öncelikle kendi beden ve ruh sağlığının yerinde olması gerekir. Gebelik döneminde yaşanan stres ve doğum sonu dönemde de emzirmenin uygun şekilde başlatılamamasının hem etkili emzirmenin sağlanması hem de doğum sonu depresyon gelişimini etkileyebileceği belirtilmektedir. Annelerin emzirme öz-yeterliliği ve depresyon riski ile ilişkisini incelemek amacı ile tanımlayıcı olarak yapılmıştır. Araştırmanın evrenini Konya ilinde bulunan 24, 15 ve 07 no’lu ASM’lere başvuran 4-6 haftalık bebeği olan, anneler oluşmuştur. Örneklem büyüklüğünün belirlenmesinde; araştırmada yer alan bağımsız değişken sayısı (41) dikkate alınarak örneklem büyüklüğü 265 olarak saptanmıştır. Araştırmada verilerin toplanmasında; literatür bilgilerden ve yapılan benzer nitelikteki araştırmalardan yararlanılarak hazırlanan bir anket formu, Doğum Sonu Depresyon Ölçeği ve Emzirme-Öz Yeterlilik Ölçeği kullanılmıştır. Verilerin değerlendirilmesinde Mann Withney U Testi, Kruskal Wallis ve spearman korelasyon analizi kullanılmıştır. Çalışmaya katılan annelerin Emzirme Öz-yeterlilik ölçeğinden ortalama 58,92±7,61, EDDÖ’den ise 9,58±5,10 puan aldığı saptanmıştır. Doğum sonu 4-6 haftalık dönemde annelerin emzirme öz-yeterlilik düzeyinin ortalamanın üzerinde olduğu ve annelerin üçte birinin (%31.7) depresyon açısından risk altında olduğu bulunmuştur. Çalışmada annelerin yaş, evlilik süresi, gebelik, doğum ve yaşayan çocuk sayısı, doğumda sorun yaşama durumu, bebek cinsiyetinden memnun olma, ilk emzirme zamanı, düzenli emzirme durumu ve emzirme konusunda kendini yeterli hissetme durumu
gibi değişkenlerin emzirme öz yeterliliğini etkilediği (p<0,05) ve emzirme öz yeterlilik düzeyi ile depresyon semptomları arasında bir ilişki olmadığı belirlenmiştir (p>0,05). Bu sonuçlar doğrultusunda, gebelik döneminden itibaren fiziksel, psikolojik ve sosyal sağlık risklerinin erken dönemde belirlenmesi, emzirmenin başlatılması ve sürdürülmesi ile doğum sonu
depresyon semptomlarının kontrolüne yardımcı olabilir. Bu nedenle sağlık profesyonellerinin gebelik ve doğum sonu dönemde danışmanlık hizmetlerinin güçlendirilmesi önerilebilir.A mother primarily should have her own physical and mental health in order to take care a
baby in a healthy manner and to breastfeed for long-term. It has been stated that the stress experienced during pregnancy and failing to start providing proper breastfeeding in the postpartum period can affect both providing effective breastfeeding and development of postpartum depression. This is a descriptive study carried out to examine the relationship between breastfeeding selfefficacy and depression risk the 4-6 weeks postpartum period.
The population of the research consists of mothers with 4-6-week-old babies admitted to 24, 15 and 07 numbered Family Health Centers in the city center of Konya. In determining the sample size; the sample size was determined as 265 considering the independent variable number(41). In collecting the data in the research, a questionnaire prepared using the literature and similar researches made, Postpartum Depression Scale and Breastfeeding-Self Efficacy Scale were used. Mann Whitney U test, Kruskal-Wallis and spearman correlation analysis were used to assess the data. It was determined that the mothers participating in the study received average 58.92 ± 7.61 points from Breastfeeding Self-Efficacy Scale, and 9.58 ± 5.10 points from EPDS. It was established that the breastfeeding self-efficacy level of the mothers in the postpartum 4-6 week was above average, and one third of the mothers (31.7%) was found to be at risk in terms of depression. It was determined in the study that the variables such as the age of mothers, duration of marriage, pregnancy, childbirth and the number of living children, problems experienced at birth, being satisfied with the baby gender, initial breastfeeding time, regular breastfeeding status and feeling self-sufficient for breastfeeding affected the breastfeeding self-efficacy (p <0.05 ) and there was no association between the breastfeeding self-sufficiency level and the symptoms of depression (p> 0.05). In line with these results, identifying physical, psychological and social health risks in the early stages from the gestation period, initiating and maintaining breastfeeding can help control the postnatal symptoms of depression. Therefore, empoweringthe consulting services of health professionals during pregnancy and the postpartum period can be suggested
Examination of Efficiency and Sufficiency of Salt-Pack Curing Method
No full textConservation defects affect leather quality adversely and cause important economic losses. Therefore, the goal of this study was to evaluate hide quality by comparing important parameters of salt-pack cured hides and determine efficiency and sufficiency of the curing method in the areas both with and without salt crystals present on the hides. The areas with and without salt crystals on the salt-pack cured hide samples, (collected from different tanneries in the Leather Organized Tannery Region, Tuzla-Istanbul-Turkey), were examined in terms of pH values, moisture and ash contents, brine saturations, total mesophile, proteolytic and lipolytic mesophile bacterial numbers. The pH values of the both areas of all the hide samples (6.3-7.4) were found to be optimum for bacterial growth. Moisture contents of the areas without salt crystals present on the hide samples (42-57%) were found to be higher than the areas with salt crystals present (31-47%). Ash contents and salt saturations of both types of area of all the hide samples (21-36% and 100% respectively) were found to be the same as standard values. Although the hides were salt-pack cured, high numbers of mesophile, proteolytic and lipolytic mesophile bacteria were isolated from both areas of the hides. Mean values of the mesophile (2 x 10(8) c.f.u./g) and lipolytic mesophile (1.7 x 10(7) c.f.u./g) bacterial numbers of the areas without salt crystals present on the hide samples were found to be higher than the areas with salt crystals. However, mean values of the proteolytic bacterial numbers were found to be similar for the both areas (1 x 10(7) c.f.u./g, 1.5 x 10(7) c.f.u./g). As a conclusion, due to an inadequately applied salt-pack curing process, this method was not a satisfactory method to prevent bacterial proliferation on hides. Hence, the traditional salt-pack curing method should be modified to improve the counter bacterial effect
A case of spinal intradural extramedullary hydatid cyst mimicking a spinal tumor
No full textA patient with multiple cystic involvements in rare locations, who is immunosuppressed due to co-existing conditions, has been presented in this case report. A 48-year-old male with numbness in the right leg and a medical history of Behçet's disease, hypertension and ankylosing spondylitis, using prednisolone, methotrexate, sulphasalazine and colchicine admitted to our hospital. He had left hemihypoesthesia below the level of thoracic vertebra 3 and bilateral Babinsky positivity. Cervical magnetic resonance imaging showed an extramedullary mass lesion in the spinal canal, at the level of first thoracic vertebra, which caused compression. Diffuse edema was noted at the spinal cord segments between cervical 5 and thoracic 2 levels. Cervical 7- thoracic 1 laminectomy was performed. The mass was totally excised. Histopathological examination confirmed the diagnosis of a hydatid cyst. Indirect hemagglutination test for echinococcosis was positive. Radiological examination showed additional cysts in lung, liver and spleen. Two cysts in liver and spleen were drained under computerized tomographic guidance. The patient is still on sulphasalazine, methotrexate and albendazole therapy and is under regular follow-up. © 2013 by Türkiye Klinikleri
