ISYU KETUANAN MELAYU DI MALAYSIA
Authors: Marzali Amri
Published: October 2021

Ketuanan Melayu” is a conception of Malay political hegemony in Malaysia. The terminology was firstly introduced by a member of Parliament of Malaysia from the United Malay National Organization, namely Dato’ Abdullah Ahmad, in a speech offered at the Institute of Intenational Affairs, Singapura, Agustus 30, 1986. The speech was originally  aimed at countering the negative propaganda proposed by the Malaysian Indian and the Malaysian Chinese, who accused that the special socio-political privileges given to the indigenous Malaysian peoples in the Malaysia’s Constitution (partaicularly in article 153) and the affirmative discriminative New Economic Policy of 1971 have been a servere strategy to condemn the Indian and Chinese Malaysians. On the other hand, the Malays in Malaysia traced the idea of Malay political hegemony from the political situation in the period of Malay kingdom of Melaka in the 15th century. They considered the period of Melaka as the golden age of Malay political sovereignty in Selat Melaka. When Melaka was occupied by the Portuegese in the 16th century, and followed by the Dutch in the 17-18th centuries, the political sovereignty of the Malays in the Malaysian Peninsula was carried on by the newly subsequent Malay kingdoms, such as Johor, Kedah, Kelantan, and others. In this article, I proposed that what is now called Malay political hegemony could be compared to what was called beschikkingsrecht in Dutch language, in the colonial period of Indonesia. This terminology was introduced by an adat law scholar, van Vollenhoven, in 1905, referring to the sovereignty of the native peoples in Malay Archipelago over their land and political state. Lastly I find the debate on the Malay political hegemony in Malaysia recently, whether between the natives versus the immigrants, or between the ruling Malays versus the opposition Malays, are pertaining with 6 articles in the Constitution and Act of Malaysian Armforce of 1972. This set of rules is knownly called Wasiat Raja-raja Melayu (The Wasiat of the Malay Sultans). Therefore, I conclude, the Malay political hegemony is constitutionalized, thus it is unnecessary for the Malays to boasting it anymore. The real problems of the Malay political hegemony now in Malaysia rests on the way it has been implemented by the Malaysian government.

Published: October 2021

BACKGROUND The human umbilical arteries form an important component involved in the exchange of materials between the foetus and the mother. Hypertensive disorders in pregnancy are responsible for a significant amount of maternal and perinatal morbidity and mortality. It complicates about 6 - 20 % of all pregnancies. Although PIH (Pregnancy-induced hypertension) is one of the major causes of maternal death, especially in developing countries; its perinatal outcomes are also not so favourable. We wanted to study the ultrastructure of Hyrtl’s anastomosis between the normotensive and hypertensive placentas. METHODS A cross-sectional study was carried out to assess the variable anatomy in Hyrtl’s anastomosis and determine the alterations of the Hyrtl’s anastomosis in the case of pregnancy-induced hypertension from the year 2017-2018 at Sikkim Manipal Institute of Medical Sciences. For TEM (transmission electron microscopy) the portion of the Hyrtl’s anastomosis was carefully dissected out and processed. The study included women with pregnancy-induced hypertension if their arterial blood pressure with systolic as ≥ 140 mm Hg and diastolic ≥ 90 mm Hg measured on two or more occasions at least after the 20th week of gestation with or without oedema. Due to an inadequate number of cases essential hypertensive cases were excluded. RESULTS From the study conducted, transmission electron microscopy revealed a disrupted muscular layer in pregnancy-induced hypertension when compared to normal Hyrtl’s anastomosis. Thickening of the muscular layer was observed in the pregnancy-induced Hyrtl’s anastomosis. Statistical Analysis - Independent t-test was considered in the analysis for continuous among the ultrastructure of the Hyrtl’s anastomosis between the normotensive and hypertensive groups. P ≤ 0.05 was considered significant. SPSS 20.0 was used for data analysis. CONCLUSIONS The effect of hypertension brought about structural changes in the blood vessel which might probably have an effect on the fetoplacental circulation and therefore adversely affecting the foetal outcome.

Effects of Anti-TPO Antibodies on the Outcome of In Vitro Fertilization-Embryo Transfer Cycles
Authors: Gadwal Bhagyashree M.
Published: October 2021

BACKGROUND The objectives of the study were to investigate whether the incidence of antithyroid antibodies (ATAs) is related to an adverse outcome in the in-vitro fertilization and embryo transfer (IVF-ET) in terms of quality of oocytes retrieved, fertilisation, cleavage, embryo quality and implantation rate (primary outcome) as compared to patients without anti-thyroid antibodies and also evaluate the association of ATAs with abortion rate, biochemical pregnancy and clinical pregnancy (secondary outcome). METHODS A total of 52 women having anti-thyroid peroxidase antibody (anti- TPO Ab) level ≥ 35 IU/mL (Cases) and 21 women having anti-TPO Ab level < 35 IU/mL (Controls) undergoing IVF / ICSI from Jan 2014 to Dec 2014 at Milann – The Fertility Centre, Bangalore, were retrospectively analysed. RESULTS There was no difference among the cases and controls for the primary outcome, viz. maturation rate, fertilisation rate, cleavage rate, implantation rate, and embryo quality. However, the abortion rate and biochemical pregnancy rate were significantly higher in the cases than in controls (P = 0.027 for each parameter). On the other hand, the clinical pregnancy rate was significantly lower among the cases (P = 0. 045). CONCLUSIONS There was no statistically significant difference in the primary outcome among the two groups. The secondary outcome of abortion rate and biochemical pregnancy rate was significantly higher in the cases than controls. The clinical pregnancy rate was significantly lower among the cases as compared to controls. Clinical Significance - Anti-TPO Ab acts as a prognostic factor and is disadvantageous to the pregnancy outcome following IVF-ET. KEY WORDS Abortion Rate, Clinical Pregnancy Rate, Fertilisation Rate, Implantation Rate, IVF/ICSI, Oocyte Maturation Rate
Complex Congenital Heart Disease in an Infant - A Case Report and Review
Authors: Naik Srinivas , Acharya Sourya , Agrawal Gajendra , Rathi Chetan , Kumar Sunil
Published: October 2021

Congenital heart disease (CHD) often poses a great diagnostic challenge for physicians. Despite antenatal diagnostic tests advancing to a great level, accurate diagnosis and treatment of congenital heart diseases is mandatory. These diseases range from mild to severe life-threatening scenarios sometimes having vague presentations making diagnosis even more difficult. Early diagnosis and treatment are usually lifesaving.1 Congenital heart diseases can often be classified as cyanotic and acyanotic based on clinical presentation. After birth, fetal structures like foramen ovale, ductus venosus and ductus arteriosus are no longer required for survival and they begin to close.2 Persistence of such structures after birth is a sign of congenital heart diseases. High mortality contributing diseases which require prompt intervention include hypoplastic left heart syndrome (HLHS), coarctation of aorta (COA), interrupted aortic arch (IAA), transposition of the great arteries (TGA), total anomalous pulmonary venous return (TAPVR), critical aortic stenosis (AS) pulmonary atresia (PA) and tricuspid atresia (TA).3 They contribute to significant mortality amongst neonatal age groups. Recognition of congenital heart diseases based on clinical fractures like cyanosis, tachycardia, tachypnoea, irritability, refusal to feed stabilisation and prompt referral to tertiary cardiac centre are critical to improve outcomes in neonates with CHDs, seizures, murmur etc is diagnostically challenging but lifesaving. Life-threatening CHDs may perhaps present with cyanosis, respiratory distress, shock or collapse; all of these are also frequent clinical presentation of various respiratory problems or sepsis in newborn. Early diagnosis and prompt treatment are the only life saving measures.
Nagaraeba – Hegel und Fujiwara no Kiyosuke
Authors: Pörtner Peter
Published: October 2021

Although there is a dispute among grammarians as to whether Japanese is a tense or aspect language, time expressions tend to be made from the perspective of the speaker, i.e. under the aspect of an event that is “now, in this moment already completed, just happening, or not yet happening.” Evidently, the notion of a threefoldedness of time perception is predominant. A comparison of different time concepts and philosophies points towards a transcultural circulation of this notion. Hegel’s philosophy exemplifies the effectiveness and shaping function of this notion of threefold time concepts. Using Fujiwara no Kiyosuke’s poem Nagaraeba, I aim to show how the thesis of the threefoldedness also of the traditional Japanese experience of time, together with the thesis of the aspect orientation of the Japanese language, may help us to interpret and understand classical waka, along the lines of the so-called “fusion of horizons” (Horizontverschmelzung) described by Hans-Georg Gadamer.

Authors: Tung Simon C. , Wong Victor
Published: October 2021

The global automotive industry is facing higher energy costs, more legislative pressure, and an ever-increasing environmental awareness to achieve fuel efficiency and environmental sustainability. In recent years the automotive industry has undergone a revolution in hardware and materials. Among these approaches, engine friction reduction and wear control by surface engineering are the most effective approaches. In this paper, surface engineering and its impact of surface coatings and texture technologies on powertrain components will be reviewed. Recently the lightweight nonferrous alloy and nanocomposites are being incorporated into the emerging powertrain technologies—including a wide range of surface coating materials such as thermal sprayed aluminum liners, diamond-like carbon-coated valve train components, and hard nitride piston rings or composite coatings toward energy-efficient and wear-resistant systems. The major section of this paper will discuss the future development trends of engine friction reduction and wear control by surface modification such as friction-reducing and wear-resistant coatings or surface textures in powertrain components. The impact of surface coatings or surface textures on tribological characteristics will be reviewed. Specifically, this review paper will address the impact of these emerging technologies on engine material requirements. The connection between surface engineering and the emerging powertrain technologies will be described. In summary, this paper will review the impact of emerging surface engineering technologies on tribological performance and future trends for advanced powertrain components. In addition, the bench and engine wear and scuffing assessments will be reviewed in terms of wear and scuffing resistance for a variety of surface coatings or textures applied to engine components. This paper also addresses the interactions between powertrain components and surface coatings or textures and their effects on friction, wear, and engine durability. The increasing importance of surface coatings and textures in engine component design and tribological performance will be fully illustrated.

Published: October 2021

Nowadays, developing simplistic, low-cost, and environment-friendly ways for the synthesis of nanoparticles (NPs) is very attractive, as reported synthesis processes with use of toxic chemicals are particularly complex. In this report, a facile and one-step approach, i.e., the sonofragmentation method, had been applied for the synthesis of FexCo1−x (x = 0.20, 0.40, and 0.80) NPs with enriched saturation magnetization and coercivity. Morphology and structure of the NPs were observed using a scanning electron microscope (SEM) and X-ray diffraction (XRD) respectively. The energy dispersive spectroscopy analysis was used for the confirmation of elemental composition. The crystalline structure of NPs was confirmed from the XRD patterns, and the crystallite size obtained from the powder XRD peak using the Scherrer equation was approximately 24.5 nm. The accumulation of NPs was observed in SEM analysis. Moreover, the magnetic property was characterized using a vibrating sample magnetometer at room temperature. The saturation magnetization (Ms) value was measured from the magnetization (M)-applied field (H) curve and found to be increased from 107 to 153 emu/g (107 to 153 Am2/kg) and the coercivity (Hc) decreased from 128 to 72 Oe (10.18 to 5.53 kA/m) for increasing the iron content in iron-cobalt NPs. Furthermore, the magnetic properties (i.e., Ms and Hc) of synthesized iron-cobalt NPs were compared with those of other methods of synthesis. The overall findings suggest that the present approach is simple, cost-effective, and environmentally safe for the synthesis of NPs.

Published: October 2021

Seed dormancy is an adaptive response of plants to environmental changes during long-term evolution. It plays an important role in plant survival and propagation. Acer cinnamomifolium, a plant species endemic to China, is an excellent garden and street tree species. However,
dormancy and germination characteristics of A. cinnamomifolium seeds are not currently known. In the present paper, the mature seeds were used as experimental materials and we investigated the effect of temperature including alternating temperature, light, after-ripening, stratification
and phytohormone on seed dormancy release and germination. After being incubated for 30 days, 0 to 10% of the seeds germinated in constant temperature (10, 15, 20, 25 and 30°C), while in alternating temperature regimes (20/10, 25/15 and 30/20°C), seed germination was < 35%. Dormancy
release and germination of seeds can be increased by after-ripening, cold stratification and phytohormone treatments. We concluded that A. cinnamomifolium seeds have a non-deep physiological dormancy. Cold stratification at 4°C for 30 days and incubation thereafter at 20°C were
found to be optimal for dormancy release and high seed germination.

Authors: Fang Guan-hua , Chen Jin-hua , Dai Xiao-fu
Published: October 2021

Background: To investigate and analyze the learning curve of totally thoracoscopic mitral valve replacement and provide a quantitative reference for cardiac surgeons to carry out the operation step by step.
Methods: The clinical data were retrospectively analyzed of 100 consecutive patients with totally thoracoscopic mitral valve replacement successively performed by the same surgeon in a single center from May 2019 to June 2020. The learning curve was divided into 2 stages by using cumulative sum analysis, and relevant surgical parameters and perioperative indicators were analyzed.
Results: The first stage of the learning curve is the skill acquisition stage, which includes 1 to 40 surgical procedures. The second stage is the proficiency stage, involving 41 to 100 operations. Among the surgical parameters of the patients in the 2 stages, detectable improvements were observed in operative time, cardiopulmonary bypass time, cross-clamp time, and intraoperative injury. After surgery, the amount of drainage, length of hospital stay, blood creatinine levels, and oxygenation index 24 h after surgery were also significantly different between the 2 groups (all P < .05). The age and sex distributions of the patients were balanced, and there was no statistically significant difference in terms of conversion to median sternotomy between the 2 stages (P > .05).
Conclusions: Cumulative sum analysis was used to accurately analyze the learning curve of totally thoracoscopic mitral valve replacement, indicating that 40 cases are needed to master the technique.
A Simplified Strengthening Methodology for Minaret Structures in Turkey: Hagia Sophia Case
Authors: Korkmaz Kasım A.
Published: October 2021

Considering various types of historical buildings in Turkey, mosqs are the most common ones. Mosqs have minaret structures standing along next to the main body with dome. The minaret buildings with their own architectural and structural characteristics, are representing the cultural and historical change in different periods over the centruies. Minarets from Ottomon period are the most widespread ones in Turkey. With its cultural synthesis through out the history, minarets from Ottomon period differ from the others with structural capability. Since Turkey is a earthquke prone country, it is very important to make existing historical structures stronger against to the seismic loads. Recently, historical structures have been strengthened with fiber reinforced polymer (FRP) composites. There are numerous of research studies are available related with strengthening using FRP composites. From this standing point, in this research, a simplified and practicale strengthening methodlogy is proposed. For the investigation Hagia Sophia Minaret structures has been used as a case study. In the analysis part, Hagia Sophia Minaret structures have been investigated through time history analyses before and after FRP composite strengthening. As a result of the present research work, displacements and stress values are determined for comparison of the structural behavior of minaret structures.

Increasingly, architects and engineers are interested in pursuing sustainable design. Yet, they lack sources that summarize best practices. As such, this review paper maps out and examines prominent examples of "sustainable" skyscrapers of varying geographic locations, climates, and socio-cultural contexts. It discusses the design themes and green features of "LEED skyscrapers" and elaborates on recent developments in architecture and engineering. The presented 12 case studies do not intend to evaluate LEED rating systems. Instead, they illustrate how LEED has advanced the green design agenda and encouraged the pursuit of innovative design and engineering solutions. The mapped-out green features in this article should be helpful to all professionals interested in green architecture.

Authors: Barrella Walter
Published: October 2021

Mangroves are complex transition ecosystems studied and affected by human activities.. This work sought information on articles in scientific journals related to environmental impacts and their forms of management and restoration and those focused on biodiversity conservation. To answer this question, we developed this work based on a scient metric survey of production with a focus on impacts and environmental and Biodiversity responses on mangroves in the last forty years (1980 to 2020), comparing mainly the global scientific production and the production in America, listing areas of research concentration, and journal, period, country and region of publication of papers. With this survey, we could observe a standardization of the research classification area and publication periods, although checking the journals found a great variety of these. As for the regionalization of studies, we could observe that, globally, the region that most contributes to the advancement in this theme is Asia; however, the country that collaborates the most, in isolation, is the United States. Although there is a diversification regarding the specific theme, the scientific production on mangroves with an environmental focus and in Biodiversity followed a global pattern in the studied period.

Authors: Avelar Luiz Eduardo Toledo
Published: October 2021

Background: The lips and perioral region are a highly dynamic anatomic area of the face and its anatomy and measurements will vary from patient to patient. In many years of clinical practice and as trainers for other injectors we have noticed that the assessment of this region is also very variable regardless of the experience of the injector. Objectives: The goal of this article is to provide a tool for assessment of the lower face and perioral area in other to simplify cosmetic treatments and help injectors identify what needs to be addressed in each patient. Methods: Over the last few years, weanalyzed the most common concerns of every patient presenting for treatment of the lips and perioral area and the most frequent areas addressed in the treatment of the lower face, and organized them into a tool that was able to systematize the different levels of attention needed in each particular area, guiding injectors towards a better final result. As trainers for other injectors, we also analyzed the most difficult aspects of the perioral assessment and simplified them into this tool that can help even novice injectors to do the correct diagnosis and therefore achieve better results while treating the perioral area. Conclusions: We believe that this tool will help both experienced and young injectors in the assessment of the lips and perioral area prior to treatment and in doing so, will provide a better outcome and cosmetic result.

Purpose. Development of a method for the regeneration of highly porous fillers for biofilters after slagging of their pores with biofilm residues in the process of growing aquaculture objects in recirculating aquaculture systems (RAS). Methodology. Regeneration of fillers was performed with solutions of sodium hypochlorite of different concentrations (2.5%, 1%, 0.5% of active chlorine) after their exploitation for 6 months. The cleaning efficiency was monitored by the difference in fillers weights after cleaning. Findings. According to the study, the use of sodium hypochlorite for cleaning highly porous fillers for biofilters (using an example of porous ceramic filler and foamed glass «JBL Micromec») is efficient and cost-effective. A reduction in the weight of the test samples averaged 12.95% for porous ceramics and 15.01% for foamed glass. Based on the obtained data, aqueous solutions with different concentrations of sodium hypochlorite do not have a pronounced difference in efficiency, respectively; the optimal for use is a 0.5% solution. Originality. The use of highly porous fillers for biofilters has long been unprofitable in fish farming due to the rapid loss of their main advantages - a high specific area per unit volume as a result of micropore slagging with biofilm residues. As a result, complete regeneration of these filter materials was required annually, which, given the significantly higher cost compared to polymeric fillers, made their use unprofitable. The described technique allows the use of porous ceramics and foamed glass, after their restoration, for a long time, with replacement only after mechanical wear. Practical value. The described method allows using highly porous fillers for biofilters in the process of growing aquaculture objects without their main disadvantage - a rapid decrease in efficiency as a result of pore slagging with biofilm residues. Keywords: RAS, biofilter, filler, restoration, sodium hypochlorite.

Purpose. Investigate ecological conditions and determine fish productivity of ponds when growing young-of-the-year carp using a suspension of chlorella. Methodology. During the study, we used methods generally accepted in hydrochemistry, hydrobiology and fish farming. Findings. The article presents the results of the study on the use of chlorella suspension in the cultivation of carp. It was found that the use of chlorella suspension created favorable hydrochemical conditions resulting in intensive development of zooplankton, which had a positive effect on the growth of young-of-the-year carp and fish productivity of the pond. The development of the natural food supply was sufficient to meet the nutritional needs of juvenile carp. The average seasonal biomass of zooplankton in the experimental pond was 28.68 g/m3 that was 1.5 times higher than in the control. The share of cladocerans in the total biomass of zooplankton in the experimental pond was 76.6%, versus 36.8% in the control. The average biomass of zoobenthos for the growing season in the experimental was 1.3 times higher than in the control, and was formed by chironomid larvae, which are valuable in the food chain. Originality. The study investigated ecological conditions and fish productivity of growing ponds under conditions of the application of cattle manure and suspension of chlorella when growing carp in monoculture. Practical value. It was found that the use of chlorella suspension promotes the intensification of the development of zooplankton organisms in ponds. The obtained data can be used to develop practical recommendations for optimizing the conditions for growing carp seeds and increasing the biological productivity of ponds. Key words: nursery ponds, natural food supply, phytoplankton, zooplankton, zoobenthos, young-of-the-year carp, chlorella suspension, fish productivity.

İşçi Dövizleri ve İthalat İlişkisi: Türkiye Örneği
Authors: ARI Ayşe
Published: October 2021

İşsizliğin ve yoksulluğun yüksek olduğu gelişmekte olan ve az gelişmiş ülkelerden daha iyi bir iş ve gelir elde etmek amacıyla işçiler gelişmiş ülkelere göç etmektedir. İşçilerin geride kalan ailelerine gönderdikleri dövizler ise gelirin gelişmiş ülkelerden az gelişmiş ülkelere transferini gerçekleştirerek önemli bir döviz kaynağı oluşturmaktadır. Böylece işçi dövizleri tasarruf-yatırım kanalıyla ülkenin ekonomik büyümesini hızlandırmaktadır. Ayrıca işçi dövizleri, göçmen ailelerini ve ülke ekonomisini çeşitli kanallarla etkilemektedir. Bunlardan ilki, gelen işçi dövizleri ile işçi ailelerinin tüketim, eğitim ve sağlık harcamalarının artmasıdır. Artan tüketim harcaması çarpan etkisiyle toplam talebi artıracaktır. Bununla birlikte işçi dövizleri, ailelerin gelirini artırdığından emek arzını azaltarak üretimin düşmesine de yol açmaktadır. Ayrıca, işçi dövizleri ülkedeki enflasyon, gelir eşitsizliği ve döviz kuru üzerinde etkili olmaktadır. İşçi dövizleri, ithalat vasıtasıyla da ülke ekonomisini etkilemektedir. İşçi dövizlerinin ithalat üzerindeki etkisi pozitif ya da negatif yönde olabilecektir. İşçi dövizlerinin ithalat üzerindeki etkisi tüketim ve sermaye mallarından hangisinin ithal edildiğine bağlı olmaktadır. Ülkede üretilebilecek malların ithal edilmesi ülkedeki üretimin azalmasına yol açacaktır. Bir başka deyişle işçi dövizleri ülkeye döviz girişi sağlarken ithalat vasıtasıyla tekrar ülkeden döviz çıkışına yol açabilmektedir.Bu çalışmanın amacı işçi dövizleri ve ithalat arasındaki ilişkiyi Türkiye için araştırmaktadır. Bu amaçla Johansen eşbütünleşme testi ile Hacker ve Hatemi (2006) bootstrap nedensellik testine yer verilmiştir. Johansen testi sonucunda işçi dövizleri ve ithalat arasında uzun dönem ilişkiye rastlanmamıştır. Elde edilen bulgulara göre, işçi dövizleri ve ithalat uzun dönemde birlikte hareket etmemektedir. Bir başka deyişle işçi dövizlerinin ithalatı pozitif ya da negatif yönde etkilemesi beklenmeyecektir. Hacker ve Hatemi (2006) bootstrap nedensellik testi bulguları ise, işçi dövizlerinden ithalata doğru tek yönlü bir nedensellik olduğunu göstermiştir.

Authors: ÖNAL Esma , YILDIZ Berk
Published: October 2021

Kurumsal finansın majör çalışma alanlarından biri olan nakit yönetiminin işletmeler için önemi, 2008 küresel finans krizi sonrasında daha da artmış ve bir işletmenin sürekliliğinin sağlanabilmesi için kârlılık faktörünün tek başına yeterli bir ölçü olmadığı daha net bir şekilde anlaşılmıştır. Kuşkusuz her sektörün kendine özgü dinamikleri ve özellikleri vardır. Ancak yoğun rekabetin yaşandığı deniz ticaret piyasasında, etkin bir nakit yönetim politikasının oluşturulması, ekonomik dalgalanmalara oldukça duyarlı olan sektör işletmelerinin sürekliliklerinin sağlanması açısından büyük önem arz etmektedir. Bu sebeple de, bu piyasada herhangi bir işletmenin tek başına egemen olması veya hüküm sürmesi, pek rastlanan bir durum değildir. Bununla birlikte, nakdin diğer varlıklara veya ödeme şekillerine göre üstünlüğünü ifade eden "nakit kraldır" deyişinin daha da önem kazandığı bu günlerde, deniz ticaret piyasası özelinde bir değerlendirme yapabilmek ve denizyolu taşımacılık işletmelerinin kurumsal nakit bulundurma politikalarını etkileyen faktörleri tespit etmek üzere bu çalışmanın yapılmasına karar verilmiştir. Finans yazınında birçok çalışma yapılmış olmasına rağmen, deniz ticaret piyasası işletmeleri üzerine yapılmış çalışma sayısı oldukça sınırlı ve yetersizdir. Bu nedenle, finans yazınına deniz ticaret piyasası özelinde katkı sağlamak için de yapılan bu çalışmanın amacı, hisse senetleri New York Menkul Kıymetler Borsasında (New York Stock Exchange) işlem gören denizyolu taşımacılık işletmelerinin nakit bulundurma politikalarına etki eden faktörlerin tespit edilmesidir. İşletmelerin yıllık verilerini içeren ve 2008-2019 dönemini kapsayan bir veri setinin kullanıldığı çalışmada, söz konusu dönemde hisse senetleri NYSE’ de sürekli olarak işlem gören 17 denizyolu taşımacılık işletmesinin, nakit bulundurma politikalarını etkileyebileceği tahmin edilen çeşitli faktörler, kurulan model yardımıyla panel veri yöntemi ile analiz edilmiştir. Elde edilen bulgulara göre NYSE’ de işlem gören denizyolu taşımacılık işletmelerinin nakit bulundurma politikaları üzerinde kârlılık ve sermaye harcamaları faktörlerinin pozitif, kaldıraç ve likidite faktörlerinin ise negatif yönlü etkileri vardır.

Şanlıurfa ili örneğinde yapılan bu çalışma kapsamında 15 yaş ve üstü olan hanehalkı sorumlusu bireylerin tercihi dikkate alınmıştır. Buna göre gerek kendi gerekse hanehalkının gelir, tüketim ve tasarruf kararlarında bulunan ve standart sorumluluklar yetisine sahip bireylerin kent içi ulaşım araçları tercihi belirlenerek, bu tercihlerin demografik özel¬likler ve sosyo-ekonomik etkenlerle olan ilişkisi orta¬ya konulmaya çalışılmıştır. Çalışmada Şanlıurfa il merkezinde ikamet eden bireylerin ulaşım tercihlerinin farklılığının, gelir, yaş, eğitim, meslek vb. diğer unsurlara göre değiştiği görülmüştür. Ancak kent içi ulaşım araçları tercihinde diğer alternatiflere göre halk otobüsü ile ulaşım tercihi yanında kendi özel aracı ile ulaşım tercihi de oldukça anlamlı sonuçlar vermiştir. Sürdürülebilir kent içi ulaşım daha çok toplu ulaşım araçları tercihine göre gerçekleşmektedir. Bu nedenle potansiyel olarak kalabalık bir nüfusa ve oldukça geniş bir yüz ölçüme sahip bir kent için toplu ulaşım araçları hizmetinde çeşitliliğin arttırılması ve olanakların iyileştirilmesi toplumsal bir ihtiyaç olmaktadır.Anahtar Kelimeler: Sürdürülebilir Kent içi Ulaşım, Ulaşım Araçları Tercihi, Tesadüfi Fayda Modelleri, Multinomial Logit Model, Şanlıurfa

Doğrudan yabancı sermaye yatırımlari, özellikle yetersiz tasarrufa sahip ülkeler için sürdürülebilir ekonomik büyüme ve kalkınma için önem taşımaktadır. Ayrıca, doğrudan yabancı sermaye yatırımları yoluyla transfer edilen sermaye, teknoloji, bilgi ve üretkenliğin, içsel büyüme teorileri kapsamında ev sahibi ülkelerin ekonomik büyümesine katkı sağlayabileceği öne sürülmektedir. Doğrudan yabancı sermaye yatırımları, yeşil alan veya kahverengi alan yatırımları olmak üzere iki türde yapılabilmektedir. Yeşil alan yatırımları şeklindeki doğrudan yabancı sermaye yatırımları istihdama doğrudan veya doğrudan yabancı sermaye yatırımları ekonomik büyümeyi artırarak istihdama dolaylı katkı sağlayabilmektedir. Ayrıca, doğrudan yabancı sermaye yatırımları bir yandan finansal sistemdeki fonları artırarak finansal sektörün gelişimine katkı sağlayabilirken, diğer yandan doğrudan yabancı sermaye yatırımları finans sektörüne rakip oldukları için finans sektörünün gelişimini olumsuz da etkileyebilmektedir. Bununla birlikte ilgili literatür dikkate alındığında; doğrudan yabancı sermaye yatırımı yapan yatırımcıların genellikle belirli bir ekonomik büyüme, istihdam ve finansal sektör gelişimine sahip olan ülkeleri tercih ettikleri görülmektedir. Bu bağlamda, teorik olarak doğrudan yabancı sermaye yatırımları ile ekonomik büyüme, istihdam ve finans sektörünün gelişimi arasında karşılıklı bir etkileşim söz konusu olabilmektedir.Dünyada 1980’li yıllardan itibaren liberalleşme ve küreselleşmenin hızlanması ile birlikte doğrudan yabancı sermaye yatırımlarında önemli artışlar olmuştur. Birçok ülke doğrudan yabancı sermaye yatırımlarının ekonomik büyüme ve istihdam üzerindeki pozitif etkilerini göz önünde bulundurarak kurumsal ve mali teşviklerle doğrudan yabancı sermaye yatırımı çekmeye çalışmaktadırlar. Bu çalışmada panel nedensellik analizi kullanılarak OECD ülkeleri örnekleminde 1995-2018 döneminde doğrudan yabancı sermaye yatırımları ile ekonomik büyüme, istihdam ve finansal gelişme arasındaki karşılıklı etkileşim incelenmiştir. Çalışma sonucunda ekonomik büyüme ile istihdamdan doğrudan yabancı sermaye yatırımlarına doğru; doğrudan yabancı sermaye yatırımlarından finansal gelişmeye doğru tek yönlü nedensellik olduğu belirlenmiştir. Bir başka deyişle ekonomik büyüme ile istihdamın doğrudan yabancı sermaye yatırımları üzerinde anlamlı bir etkiye sahip olduğu, doğrudan yabancı sermaye yatırımlarının ise finans sektörünün gelişimi üzerinde anlamlı bir etkiye sahip olduğu tespit edilmiştir.
Sınıf Öğretmeni Adaylarının Bilgi Arama ve Yorumlama Davranışları: Ay’ı Gözlemliyorum

İnsanın kişisel deneyimiyle elde ettiği ya da kanıtlanarak ortaya konan sistematik düşünceler bütünü olarak tanımlanabilecek bilgi kavramı insan hayatının büyük bir kısmında yer almaktadır. İnsanlar en basitinden en karmaşığına kadar tüm sorularına bilgi arayarak cevap bulmaya çalışırlar. İnternetin, arama motorlarının ve web sitelerinin ortaya çıkmasıyla bilgi bulma kaynaklarının değiştiği bilinmektedir. Bu nedenle bireylerin bilgi arama ve yorumlama davranışları araştırma konusu olmuştur. Çalışmanın temel amacı da sınıf öğretmeni adaylarının bilgi arama ve yorumlama davranışlarını ortaya koymaktır. Belirlenen amaç doğrultusunda yapılan çalışmada karma yöntem tercih edilmiş olup “Üçgenleme Tasarım: Yakınsama Modeli” kullanılmıştır. Araştırmanın çalışma grubunu sınıf öğretmenliği lisans programı birinci sınıfta öğrenim gören 58 öğrenci oluşturmuştur. Öğretmen adaylarının bilgi arama ve yorumlama davranışlarını ortaya çıkarmak amacıyla ilk olarak Web Ortamında Bilgi Arama ve Yorumlama Stratejileri Ölçeği uygulanmış, olası farklılıkları ortaya çıkarmak için de bilgi arama ve yorumlama davranışlarını sergileyecekleri ödev verilmiştir. Bununla birlikte öğretmen adaylarının ödevlerinde kullandıkları kaynaklara yönelik görüş bildirdikleri Kaynak Kullanımına Yönelik Görüş formu kullanılmıştır. Bulgular incelendiğinde sınıf öğretmeni adayları Web Ortamında Bilgi Arama ve Yorumlama Stratejileri Ölçeğinden bilgiyi organize etme stratejisinde en yüksek değeri aldığı görülmüştür. Nitel veriler incelendiğinde ise adayların çoğunluğunun gözlem verilerini ödevlerinde kullanmadıkları; güvenilir bilgi edinmek amacıyla ödevlerinde farklı kaynaklar kullandıkları, daha çok internet ansiklopedilerini ve basılı kaynaklardan yararlandıkları, farklı kaynakları karşılaştırarak ya da bilginin bulunduğu web sayfasının özelliklerine dikkat ederek kaynakların güvenirliğini belirledikleri, çoğunluğunun kaynakça kullanımının önemini kavrayamama ve kaynak gösterme ilkelerini bilmemeleri sebebiyle kaynakçaya yer vermedikleri görülmüştür. Kaynakçaya yer verenler ise bu durumu bilginin kaynağını kanıtlamak ve hukuki ve ahlaki bir yükümlülük olması sebebiyle yaptıklarını belirtmişlerdir. Tüm bu sonuçlar dikkate alındığında daha sonraki çalışmalar için adayların bilgi arama ve yorumlama davranışlarının süreç içinde değerlendirilmesi, adayların kendi bilgi arama davranışları hakkında ne düşündüklerinin ortaya çıkarılması önerileri sunulabilir.

Clinico-electrophysiological analysis of the most common in Russia family selection, having a particular form of demyelinization neuropathy hereditary neuropathy with predisposition to compression paralyses (HNPCP) has been presented. In all the families the diagnosis has been confirmed with the help of DNA diagnostics, based upon revealing of typical deletion in chromosome field 17.p.11.2. Besides a classical recurrent variant some other phenotypes of the disease have been described: recurrent positional sensoric symtoms, progressing mononeuropathy, progressing polyneuropathy. Electrophysiological signs have been determined, which are the most informative for HNPCP. These signs can used for clinical diagnostics of the disease followed by DNA diagnostics. Relative incidence of this special form of neuropathy among acquired compression mononeuropathies (6%) and their recurrent variants (50%) has been counted.
