Jeopolitik Risklerin ve Savunma Harcamalarının İktisadi Büyümeyle İlişkisi: MIST Ülkeleri Örneği
Authors: DEMİRCİ Onur , AYYILDIZ Fatih Volkan
Published: September 2023

Savunma harcamalarının GSYH içindeki payının yüksek oluşu bazı ekonomilerde büyüme üzerinde olumsuz bir etki yaratmaktadır. Arz yönlü iktisatçılar bu etkinin, kaynakların daha verimli ve üretime dönük alanlarda değerlendirilmesiyle giderilebileceğini savunmaktadır. Keynesyen görüş ise askeri harcamaların çarpan mekanizması yoluyla iktisadi büyümeyi pozitif etkileyebileceğini öne sürmektedir. Bu argüman, artan savunma harcamalarının toplam harcamaları artıracağını, toplam harcamaların da toplam talebi artıracağını ve böylece iktisadi büyümenin ivme kazanacağı anlayışına dayanmaktadır. Savunma harcamaları sürekli yüksek seyreden ülkelerde bu duruma sebebiyet veren faktörler arasında savaş, deprem ve göçmen sorunları gibi jeopolitik riskler de gösterilebilir. Bu riskleri yüksek olan ülkelerin savunma harcamalarının da GSYH içinde görece önemli bir paya sahip olduğu gözlenebilmektedir. Ekonomi yazınında savunma harcamaları ve ekonomik büyüme ilişkisi üzerine geniş bir literatür mevcut iken jeopolitik risklerin bu denkleme dahil olduğu çalışmalar az sayıdadır. Bu çalışma jeopolitik riskler ve savunma harcamalarının iktisadi büyüme ile nedensellik bağının varlığını MIST ülkeleri (Meksika, Endonezya, Güney Kore ve Türkiye) kapsamında tahmin etmeyi amaçlamaktadır. Çalışma kapsamında jeopolitik risklerin ölçümü için GPR endeksi (Caldara & Lacoviello, 2022) kullanılarak Dumitrescu & Hurlin (2012) panel nedensellik testine başvurulmuştur. Sonuçlar büyümeden her iki değişkene doğru geri beslemeli nedenselliğe dair kanıtlar sunarken jeopolitik riskten savunma harcamalarına doğru bir nedenselliğe de işaret etmektedir.
The Effects of Globalization and Multinational Companies on Turkey’s Export
Authors: ERKÖK Banu
Published: September 2023

With globalization, historical blocks have emerged ascribing a vital place to globalization and the worldwide integration of capital. Those blocks asserted globalization’s unquestionable acceptance and supported and advocated it. Consequently, developing countries, including Turkey, started to adopt policies to promote foreign direct investment via different incentives to eradicate the lack of capital and technology in the 1980s. Turkey presents those support to those multinational companies across a variety of industries, including automobile, chemicals, and energy. In fact, Turkish exports have risen more than seventy-five-fold, reaching 225 billion dollars in 2021, compared to 1980. Those multinational companies also played a major role in this increase. The share of those companies’ exports in total export was approximately 18 percent between 2007 and 2017. However, their share commenced declining in 2019 which fell to 12 percent in 2021. Besides examining the top ten exporters of Turkey in 2021, we see that half of them are multinational companies, operating in the automotive sector. Moreover, the said sector was the leading exporter for more than 15 years till 2022. Assessing the foreign trade figures of those multinationals in the automotive sector, we see that their imports are also large, particularly those from their production centers. Such that they import approximately 70 units against 100 units of exports. This phenomenon severely deteriorates the current account balance of Turkey.

Published: September 2023

1980 sonrası süreçte neo-liberal politikaların uygulanmasıyla birlikte serbestleşmeye başlayan finans kesiminin geldiği noktayı ifade eden finansallaşma kavramı son dönem çalışmalara konu olmaktadır. Finansallaşmanın özellikle gelir dağılımını bozucu yöndeki etkisinin mercek altına alındığı çalışmalar bu faktörün ana akım çalışmalarda ihmal edildiğini ortaya koymaktadır. Öncelikle gelişmiş ülkelerde ortaya çıkan ve daha sonra gelişmekte olan ülkelerde belirginleşen finansallaşma olgusu, şirketlerin, hane halklarının ve devletin davranış kalıplarını değiştirmekte ve günümüz kapitalizminin dinamiklerini yerinden oynatma rolünü üstlenmektedir. Bu kapsamda bu çalışmanın amacı 1988-2019 döneminde Türkiye’de finansallaşmanın milli gelir içerisindeki emek payı üzerindeki etkisini zaman serisi analizi ile araştırmaktır. Analizde finansallaşmayı temsilen kullanılan finansallaşma endeksi bu çalışma kapsamında Temel Bileşenler Analizi kullanılarak özgün olarak elde edilmiştir. ARDL eş-bütünleşme yaklaşımının kullanıldığı analiz sonuçlarına göre Türkiye’de finansallaşma, teknolojik gelişme ve dış açıklık değişkenlerinden sonra emek payının aşınmasında rol oynamaktadır. Dolayısıyla çalışma sonuçlarına göre, düzenlemelerden büyük oranda muaf tutulan finansal kesimin finansallaşmaya olan dönüşümü, Türkiye ekonomisi üzerinde fonksiyonel gelir dağılımını bozucu bir etkiye sahiptir.
Postmodern Görüşlerin Yoksulluk Yazınına Katkısı Üzerine Bir Değerlendirme
Authors: KAÇANOĞLU Mesut
Published: September 2023

Yoksulluk, başta azgelişmiş ülkeler olmak üzere tüm ülkelerde önemli bir sorundur ve genellikle gelirle ilişkilendirilir. Bireyler, gelirleri belirli bir düzeyin altına düştüğünde yoksul kabul edilirler. Kalkınma, yoksullukla mücadele ve modernleşme gibi kavramlar zengin ve yoksul ülke ayrımına ve yoksul ülkelerin zengin ülkelerin yardımıyla gelişeceği varsayımına dayanmaktadır. Bu varsayıma göre kalkınma politikaları ile yoksulluk azaltılacak ve azgelişmiş ülkelerin hayat seviyeleri yükseltilecektir. Azgelişmiş ülkelerde, gelir artışlarının ve büyümenin hedeflenmesi, onları bu dönüşümleri yaşamış, modernleşmiş, sanayileşmiş ve kalkınmış zengin ülkelere bağımlı hale getirir. Kalkınma söyleminin özetlenen bu bölümünün teorik yapısı modernist görüşlerce şekillendirilir. Postmodern görüşler, 1980 sonrası dönemde özellikle sosyal bilimlerde eleştirel bir alan oluşturmuş ve söylem analizi yardımıyla kalkınma ve yoksulluk yazınını, birer söylem olarak değerlendirmiştir. Kalkınma ve yoksulluk gibi kavramlar postmodern bir mercekle deşifre edildiğinde, bu sorunların tanımlanmasında ve bu sorunlarla mücadelede önemli farklılıklar ortaya çıkar. Postmodern görüşlerde yoksulluk yazınında önemli yere sahip olan kıtlık, sınırsız istekler, sınırlı kaynaklar, ihtiyaçlar vb. kavramların kalkınma söylemince geliştirilen bilinçli birer kurgunun araçları olduğu vurgulanır. Bu çalışmada, postmodern görüşlerin yoksulluk yazınına yönelttikleri eleştiriler ele alınmakta ve bu durumun yoksulluk ve yoksullukla mücadele konularında ortaya koyduğu farklı bakış açıları irdelenmektedir.

Published: September 2023

Since camping is a concept that shares common features with extraordinary emotional experiences such as social interaction, self-renewal and relaxation in relation to nature, it is a very popular recreational activity today. The aim of this study is to examine the behaviors, attitudes and camping experiences of individuals who are members of camping virtual communities in Turkey. For this purpose, netnography method was used in the study. Netnography is a special approach that allows ethnographic research on the Internet. During the data collection process, the most actively used forum and Facebook pages related to camping were examined. According to the findings of this study, five main categories as "search for knowledge", "technical information", "recommendations", "dangers" and "camp diaries" and seven subcategories as "beginners", "campsite rush", "getting into a sleeping bag", "cold related issues", "fighting insects", “experience" and "pleasure" are reported. In line with the emerging categories, it is seen that individuals who are members of camping virtual communities share information and experience with each other on many camp-related issues, as well as make recommendations.

Published: September 2023

Various studies have been carried out to improve the parameters of soil mechanical properties. Efforts to improve the mechanical properties of the soil can be carried out in multiple ways, including automated means through compaction and chemical means through the addition of cement base materials. To improve the stability and properties of the subgrade soil, the cement base material that is commonly used is Portland Composite Cement (PCC). In several studies, apart from cement base materials, waste base materials have also been used for stabilization subgrade. This includes using bleached soil residues and rice husk ash as additives to stabilize the soil. The results showed that the use of soil bleaching waste in soil cement stabilization can be used to improve the mechanical properties of the embankment soil and the composition of the soil bleaching waste mixture so that mechanically, it is proven to provide the most effective improvement so that it can be used for road foundation layers made of cement soil. As part of this research, many tests can be carried out on normal and stabilized soils. Various percentages of SBE are 5%, 10%, 15%, 20%. PCC is introduced into the soil at a rate of 8% of the dry weight of the soil.

Indium phosphide quantum dots have become an industrially relevant material for solid-state lighting and wide color gamut displays. The synthesis of indium phosphide quantum dots from indium carboxylates and tris(trimethylsilyl)phosphine (P(SiMe3)3) is understood to proceed through the formation of magic-sized clusters, with In37P20(O2CR)51 being the key isolable intermediate. The reactivity of the In37P20(O2CR)51 cluster is a vital parameter in controlling conversion to quantum dots. Here, we report structural perturbations to In37P20(O2CR)51 clusters induced by tuning the steric properties of a series of substituted phenylacetate ligands. This approach allows for control over reactivity with P(SiMe3)3, where meta-substituents enhance the susceptibility to ligand displacement and para-substituents hinder phosphine diffusion to the core. Thermolysis studies show that with complete cluster dissolution, steric profile can modulate the nucleation period, whereas partial dissolution from indium carboxylate loss results in conversion to uniform InP cores with a narrow, 419 nm absorbance. The enhanced stability from ligand engineering also allows for the isolation and structural characterization by single-crystal X-ray diffraction of a new III-V magic-sized cluster with formula In26P13(O2CR)39. This intermediate is thought to precede the In37P20(O2CR)51 cluster on the InP reaction coordinate. The physical and electronic structure of this cluster are analyzed, providing new insight into previously unrecognized relationships between II-VI and III-V materials and the discrete growth of III-V cluster intermediates.
Rapid building block-economic synthesis of long, multi-O-GalNAcylated MUC5AC tandem repeat peptides
Authors: Galashov Arseniy , Kazakova Ekaterina , Stieger Christian , Hackenberger Christian , Seitz Oliver
Published: September 2023

The study of mucin function requires access to highly O-glycosylated peptides with multiple tandem repeats. Solid-phase synthesis would be a suitable method, however, the central problem in the synthesis of mucin glycopeptides is the need to use precious and potentially vulnerable glycoamino acid building blocks in excess. In this article, we report the development of a method based on SPPS and native chemical ligation/desulfurization chemistry that allows the rapid, reliable, and glyco-economical synthesis of long multi-O-GalNAcylated peptides. To facilitate access to the glycosyl donor required for the preparation of Fmoc-Ser/Thr(Ac3GalNAc)-OH we used an easily scalable azidophenylselenylation of galactal instead of azidonitration. The problem of low yield when coupling glycoamino acids in small excess was solved by carrying out the reactions in 2-MeTHF instead of DMF and using DIC/Oxyma. Remarkably, quantitative coupling was achieved within 10 minutes using only 1.5 equivalents of glycoamino acid. The method does not require (microwave) heating, thus avoiding side reactions such as acetyl transfer to the N-terminal amino acid. This method also improved the difficult coupling of glycoamino acid to the hydrazine-resin and furnished peptides carrying 10 GalNAc units in high purities (>95%) of crude products. Combined with a one-pot method involving native chemical ligation at a glycoamino acid junction and superfast desulfurization, the method yielded highly pure MUC5AC glycopeptides comprising 10 octapeptide tandem repeats with 20 -O-linked GalNAc residues within a week.
Combining Donor Strength and Oxidative Stability in Scorpionates: A Strongly Donating Fluorinated Mesoionic Tris(imidazol-5-ylidene)borate Ligand

Published: September 2023

Strongly donating scorpionate ligands support the study of high-valent transition metal chemistry; however, their use is frequently limited by oxidative degradation. To address this concern, we report the synthesis of a tris(imidazol-5-ylidene)borate ligand featuring trifluoromethyl groups surrounding its coordination pocket. This ligand represents the first example of a chelating poly(imid- azol-5-ylidene) mesoionic carbene ligand, a scaffold which is expected to be extremely donating. The {NiNO}10 complex of this ligand, as well as that of a previously reported strongly donating tris(imidazol-2-ylidene)borate, have been synthesized and characterized. This new ligand’s strong donor properties, as measured by the υNO of its {NiNO}10 complex and natural bonding orbital second-order pertur- bative energy analysis, are on par with those of the well-studied alkyl substituted tris(imidazol-2-ylidene)borates which are known to effectively stabilize high-valent intermediates. The good donor properties of this ligand, despite the electron withdrawing trifluorome- thyl substituents, arise from the strongly donating imidazol-5-ylidene mesoionic carbene arms. These donor properties, when combined with the robustness of trifluoromethyl groups towards oxidative decomposition, suggest this ligand scaffold will be a useful platform in the study of oxidizing high-valent transition metal species.
Keep it singlet – Towards in silico design of manganese catalysts for olefin metathesis
Authors: Pecak Jan , Talmazan Radu A. , Kirchner Karl , Podewitz Maren
Published: September 2023

Olefin metathesis is one of the most significant transformations in organic chemistry and an excellent example for efficient homogeneous catalysis. Although most currently used catalysts are primarily based on 4d and 5d metals, cycloaddition and cycloreversion reactions can also be attributed to first-row transition metals, such as iron. Surprisingly, the potential of Mn(I) based catalysts for olefin metathesis has been unexplored, despite its prominence in homogeneous catalysis and its diagonal relationship to Ru(II). In the present paper, we have investigated the prospective capabilities of rationally designed Mn complexes for cycloaddition and reversion reactions, using density functional theory. To keep our model complexes as synthetically feasible as possible, we included CO as co-ligands and imposed octahedral coordination. Like iron systems, a singlet ground state is required for Mn based catalysts to facilitate olefin metathesis and to prevent undesired cyclopropanation. However, the stabilization of the singlet state requires a careful selection of σ-donor and π-acceptor properties. Our results show that bidentate ligands in conjunction with CO work best. Our findings support the isodiagonal relationship and show the viability of Mn(I) complexes as catalysts for olefin metathesis.

There has been significant advancement in display technology in recent times. However, synthetic efforts toward designing more efficient emitters are still underway. TADF emitters offer the advantage of an all organic based design with IQEmax of 100%. To study the effect of phenanthroline-based moieties, we designed and synthesized two yellow-green thermally activated delayed fluorescent (TADF) emitters, DICz-DBPZ and DICz-DPPN. Due to structural variations associated with steric strain, the two emitters displayed different photophysical and organic light-emitting diode (OLED) performances. For DICz-DPPN, the absorption and emission maxima were recorded at 313-368 nm and 516 nm, respectively, while for DICz-DBPZ, they were observed at 311-393 nm and 559 nm. The DPPN-substituted TADF emitter had an EQE of 5.0% and color coordinates of (0.37, 0.53), whereas the DBPZ-substituted emitter displayed a high EQE of 15% with color coordinates of (0.47, 0.51). Due to the closed structure of DICz-DBPZ, thermal decomposition temperature occurred at 269oC as compared to 213oC for DICz-DPPN, which significantly influenced the difference in EQE between the two emitters. In order to simultaneously obtain high EQE and a long lifetime, this study offers an approach to synthesize yellow TADF emitters by utilizing a combination of diindolocarbazole (DICz) and 1,10-phenanthroline-5,6-diamine as a stable donor-acceptor.

India has had a variety of the world’s greatest earthquakes within the last century. In fact, quite one half area within the country is taken into account vulnerable to damaging earthquakes. The seismic building design code in India (IS 1893, Part-I) is additionally revised in 2002. The magnitudes of the look seismic forces are considerably enhanced generally, and also the seismic zonation of some regions has also been upgraded. There are many literature (e.g., IITM-SERC Manual, 2005) available that presents step-by- step procedures to gauge multi-storeyed buildings. The attention for existing bridges is relatively less. However, bridges are important components of transportation network in any country. The bridge design codes, in India, don’t have any seismic design provision at this time. A outsized number of bridges are designed and constructed without considering seismic forces. Therefore, it is important to gauge the capacity of existing bridges against seismic force demand. There are presently no comprehensive guidelines to help the practicing structural engineer to gauge existing bridges and suggest design and retrofit schemes. So as handle this this problem, this work aims to hold out a seismic evaluation case study for an existing RC bridge using nonlinear static (pushover) analysis. Nonlinear static (pushover) analysis as per FEMA 356 isn’t compatible for bridge structures. So, within the present study an improved pushover analysis is additionally won’t to verify the results.

The bubble deck technology developed in Europe makes use of high-viscosity concave polyethene spheres to replace the ineffective concrete in the centre of the slab, therefore dwindling the dead weight and adding the effects of the bottom. This system is used in the concrete floor system. Concrete is good in contraction and hence is more useful in the contraction region than in the pressure region. The reduction in concrete can be done by replacing the pressure zone concrete. An experiment has been carried out to find out the effectiveness of plastic bubbles by replacing concrete in the pressure zone of Ordinary Portland Cement Concrete (OPCC) and Geo-Polymer Concrete (GPC) slab. Constituents named are cement, sand, and coarse aggregate for OPCC and for GPC cement is fully replaced with 70% fly ash, 15% GGBS and 15% glass powder. NaOH(12M) alkaline solution is added instead of water for GPC. In this design, M45 concrete blend is used to prepare both OPCC and GPC slabs. The trial blend is tested for compressive strength in 7 days and 28 days. A flexure test is done for 7 days and 28 days of curing of the beams. The procedure is repeated for beam samples with bubble mesh and bubble mesh along with shear underpinning. Relative analysis of the OPCC and GPC slabs is done to observe the chance reduction in tone-weight and cost-effectiveness. Analysis of the geste of the GPC beam in comparison with that of the OPCC beam is also carried out.

Temperature variations within the rigid pavement structure induces many distresses. Knowledge of temperature effects is essential for the design and maintenance requirement. The temperature differential depends mainly on the thickness of slab and the grade of concrete.

Fault diagnosis technology is crucial for the safety and stability of the operation of wind turbines. Efficient wind turbine fault diagnosis technology quickly identifies the types of failures in order to reduce the operating and maintenance costs of wind farms and improve the efficiency of power generation. The majority of wind farms currently use supervisory control and data acquisition (SCADA) systems to acquire operation and maintenance data. SCADA systems are rich in data pertaining to the working parameters of wind turbines. Moreover, fault diagnostic functionality is not common in SCADA systems. SVMs are a common intelligence technique used in the fault diagnostics of wind turbines. The choice of SVM parameters is essential for precise model classification. The penalty factor and kernel function parameter of SVM were optimi zed in this study along with the construction of the SSA-ABC wind turbine defect detection model using the Artificial Bee Colony (ABC), a brand-new and very effective optimization technique. Data are obtained from a wind farm SCADA system and, after pre-processing and feature selection, entail a faulting set. Evidence suggests that the ABC-SVM diagnostic model, which has a quick convergence rate and a potent optimization capability, effectively enhances the accuracy of wind turbine fault diagnosis when compared to the GS-SVM, GA-SVM, and PSO-SVM models. The ABC-SVM diagnostic model may also be utilized in real-world engineering applications to identify defects.

Improper weed control methods can cause about 30–35% reduction in crop yield. Mechanical weed control on ridges is still a major problem. A ridge profile power weeder was designed and developed for weeding of ridge planted crops. The main working components of the weeder were cutting blades and rotor shaft. Three types of blades (L-type, C-type and Flat-type) were selected having length, width and thickness of 100 mm, 25 mm and 6 mm, respectively, operating with a rotor shaft of 18 mm in diameter. C-type blades were most suitable at gang speed of 200 rpm and 15.26±0.96% (d.b) soil moisture content with weeding efficiency, plant damage, field capacity of 91.37%, 2.66%, and 0.086 ha.h-1, respectively. Time saving with ridge profile power weeder as compared to manual weeding was 92.97 per cent.

It affects human body through breathing and since this pollution is barely visible in eye, a monitoring system is necessary to stay cautious. This is the motivation behind our work so that in hospital all people can stay aware of the toxic gas (CO) they are breathing. Our objective is to provide a system to measure continuous Air Quality in hospital environment and AQI level using gas sensors and also an inbuilt fire detector is present to determine fire out broken. We proposed a portable model in which monitoring sensors are connected through IoT technology. From previous dataset we got high accuracy. In this model our aim to detect the toxic gas and fire outbreak by using the gas sensor MQ2, MQ7, MQ135 and flame sensor. When the toxic gas is detected, the vacuum can automatically run and suck the toxic gas. In addition to this, it provides alert to the main device which is connected through IOT and buzzer. we included fire detector, DHT11-temperature and moisture to maintain the environment in hospital. Whenever the temperature and moisture are crossed the normal range, it gives alert to the device (mobile) by Bluetooth. Also, we're going to use the air purifier model to reduce the problems.

Çağımızın en önemli küresel sorunlarından biri haline gelen iklim değişikliği, pek çok sektörde olduğu gibi turizm sektörü üzerinde de hem etkisini göstermekte hem de sektöre bağlı gerçekleşen faaliyetlerden etkilenmektedir. Turizm sektörü ile iklim değişikliği arasındaki bu iki yönlü ilişki turizm literatüründe sosyal, ekonomik ve ekolojik açıdan da tartışılmaktadır. Bilimsel çalışmaların yanı sıra iklim değişikliği konusunda toplumsal bir farkındalığın oluşması da önem arz etmektedir. Kitle iletişim araçları ise bu farkındalığın oluşmasında önemli bir rol oynamaktadır. Bu bağlamda çalışmanın amacı, kitle iletişim araçlarından biri olan gazetelerde turizm ve iklim değişikliğine ilişkin haberleri incelemektir. Araştırmanın amacı doğrultusunda Türkiye’de en yüksek tiraja sahip 10 gazetenin internet siteleri üzerinden 2022 yılı 15 Ağustos-15 Eylül tarihleri arasında iklim değişikliği ve turizme ilişkin içeriklere sahip haberler incelenmiştir.Erişilen 187 haber metni üzerinde karma içerik analizi yapılmıştır.Sonuçlar, doğrudan iklim değişikliği ve turizm ile ilgili sınırlı sayıda haber (13 haber) olduğunu göstermiştir. İklim değişikliği ile ilgili haberlerin ise daha çok kuraklık, orman yangınları, biyoçeşitlilik kaybı gibi iklim değişikliğinin genel etkileri, iklim değişikliğinin insan ve diğer canlı türleri üzerindeki etkileri ve sıcaklık artışı kapsamında ele alındığı tespit edilmiştir.
