Is the Export-Led Growth Model Valid in Emerging Economies? The Role of Intellectual Capital
Authors: Tung Le Thanh
Published: June 2024

In recent years, emerging economies have been considered a new growth engine of the global economy. This study tests the export-led growth hypothesis with a sample of 31 emerging economies. Unlike other studies, in this research, intellectual capital is used as a variable affecting economic growth. The database for the study covers the period 1992–2019 and is divided into two sub-samples and two sub-periods. The study’s results make some notable contributions to the current literature. First, they confirm the export-led growth hypothesis in these economies. This empirical finding is the first evidence of this with the largest sample of emerging economies, filling an empirical research gap in the contemporary literature. Second, intellectual capital is found to have a positive impact on economic growth both directly and indirectly, in upper-middle-income countries. However, the positive effect of this variable is not confirmed in the lower-middle-income group. Third, education is considered a key factor supporting economic growth based on all estimated results. Conversely, pollution and poverty have a negative influence on economic growth in most study samples. Lastly, we derive some policy implications for improving economic growth in these emerging economies in the future.

Published: June 2024

This paper aims to study the synergies between budget transparency (proxied through the Open Budget Index) and good governance (measured through each of the 6 Worldwide Governance Indicators), with overall effects on human development (measured by the Human Development Index). Based on the literature underpinnings, most of the previous studies were based either on the bidirectional analysis of the influences exerted by budget transparency on the 6 pillars of governance, or on studying the relationship between good governance and the development prospects of states. Therefore, our study highlights the influences exercised on the level of human development, documenting the simultaneous causality of our coordinates, within the selected states. The sample includes 14 EU member states, selected according to the availability of reported budget transparency, for the period 2006-2021. The research methodology embeds a three-fold approach that relies on advanced modeling through robust regression models, structural equations modeling and Gaussian Graphical Models. The obtained results suggest that improving governance and human development can help promote budget transparency, and greater budget transparency can support better governance and higher human development by ensuring efficient use of public resources, considering the political factor as well.

Published: June 2024

The Knowledge of the causes of damage of materials is a priority for design engineers to avoid sudden failure of equipment in service. One of the most important reasons for the failure of materials is fatigue, this phenomenon can be defined as damage to the metal under repeated stress and lower than the yield stress. The main objective of this study is the development of multiaxial fatigue criterion using total strain energy, then validating this proposal by the results of literature and a comparison with another criterion. The majority of the results obtained by our proposal give conservative results. These predicted results are compared with bending-torsion tests and the agreement is found to be fairly good.

Authors: Appel Giselle , Shahzad Ahmed T. , Reopelle Kestrel , DiDonato Stephen , Rusnack Frances , Papanagnou Dimitrios
Published: June 2024

Purpose: During the third-year emergency medicine (EM) clerkship, medical students are immersed in traumatic incidents with their patients and clinical teams. Trauma-informed medical education (TIME) applies trauma-informed care (TIC) principles to help students manage trauma. We aimed to qualitatively describe the extent to which students perceived the six TIME domains as they navigated critical incidents during their EM clerkship. Methods: We employed a constructivist, modiﬁed grounded theory approach to explore medical students’ experiences. We used the critical incident technique to elicit narratives to better understand the six TIME domains as they naturally appear in the clerkship. Participants were asked to describe a traumatic incident they experienced during the clerkship, followed by the clerkship’s role in helping them manage the incident. Using the framework method, transcripts were analyzed 1) deductively by matching transcript excerpts to relevant TIME domains and 2) inductively by generating de novo themes to capture factors that affected students’ handling of trauma during critical incidents. Results: Twelve participants were enrolled and interviewed in July 2022. “Safety” was the most frequently described TIME domain, whereas “Gender, Cultural, and Historical issues” and “Peer Support” were discussed least. Inductive analysis revealed themes that hindered or supported their ability to manage traumatic experiences, which were grouped into three categories: 1) student interactions with the learning environment: complex social determinants of health, inequalities in care, and overt discrimination; 2) student interactions with patients: ethically ambiguous care, witnessing acute patient presentations, and reactivation of past trauma; and 3) student interactions with supervisors: power dynamics, invalidation of contributions, role-modeling, and student empowerment. Conclusion: The six TIME domains are represented in students’ perceptions of immediate, stressful critical incidents during their EM clerkship, with “Safety” being the most commonly described; however, the degree to which these domains are supported in students’ experiences of the EM clerkship differ, and instances of inadequately experienced domains may contribute to student distress. Understanding the EM clerkship through the speciﬁc lens of students’ experiences of trauma may be an effective strategy to guide curricular changes that promote a supportive learning environment for students in the emergency department.

Authors: Zimarin M. , Kochergina Marina
Published: June 2024

Shrubs are the most important component of the modern cultural landscape. They are highly appreciated in landscaping public spaces and are indispensable in creating spectacular and sustainable compositions on individual development sites. The relevance of these studies is due to the increased interest of the population in various groups of ornamental shrubs as a means of creating an expressive landscape. The paper presents the results of studying the assortment of shrubs of the Rosaceae Juss., which are most popular in modern landscape design. The increased interest in these plants is due to their high decorative properties in combination with moderate requirements for soil and climatic factors, winter hardiness and frost resistance in the conditions of the Voronezh region. The species presented in the research belong to the groups of beautifully flowering, decorative deciduous and decorative fruiting shrubs. Many of them combine these qualities. The most important decorative features of plants include the shape of their aboveground part, which is largely determined by the branching system of shoots. Various crown construction systems allow us to perceive plant objects in a three-dimensional way, like geometric bodies. The research presents shrubs with rounded, spreading, cushion-shaped, umbrella-shaped, hemispherical dense or openwork crowns. Bioecological features and a complex of decorative qualities make it possible to use the plants in question in single and row plantings, landscape groups, to create edges, miniature plantings, hedges, as a background or accents in flower beds.

Published: June 2024

Apricot is in high demand among the population of all over the world. The fruits are used fresh and processed. They are distinguished by high technological properties, they are used in the food, confectionery, and perfumery industries. The world produces apricot products from 1 million to 1 million 300 thousand tons per year, An important direction for increasing fruit production is the creation of the most resistant varieties to biotic and abiotic environmental factors. Apricot trees have intensive growth, early fruiting and ripening, and high yields. The lack of varieties with high winter hardiness restrains the wide spread of the crop, but with a rational approach to the choice of region, site for the garden, selection of assortment and with appropriate agricultural techniques, apricots can be productive and profitable. To reduce the growth of trees, clonal rootstocks are required, which determine many economic and biological characteristics of the variety, such as the survival rate of varieties, the strength of tree growth, their early fruiting and yield. Each variety and rootstock is selective in relation to each other, so scientists create rootstocks adapted to certain growing conditions. For a heat-loving crop with intensive tree growth, clonal rootstocks are required, which have high winter hardiness, good propagation by green and woody cuttings and are compatible with apricot varieties.

Authors: Abramova E. , Vostrikova A. , Kiryanova S.
Published: June 2024

In recent years, there has been an increase in the number of diseases caused by phytopathogenic fungi. These pathogens infect plants at different stages of their growth and agricultural production. At the same time, increasing preference is given to biological control in comparison with traditional agrotechnical measures, for example, treatment with chemical fungicides. In this regard, the study of crops that compete with pathogens and suppress them is of particular relevance. These include micromycetes of the genus Trichoderma. They have repeatedly become the subject of research aimed at studying their antagonistic activity, including with the aim of developing strategies to increase the effectiveness of biological control. But, despite this, information regarding the specifics of a number of species of micromycetes of the genus Trichoderma, their capabilities and prospects for use remains unstudied. In this work, we turn to the consideration of the antagonistic activity of strains of micromycetes of the genus Trichoderma (T.longibrachiatum, T.harzianum and T.asperellum) in relation to fungi of the genera Aspergillus, Rhizopus, Alternaria and Mucor, causing diseases of agricultural plants and humans, with their further use in the development of a biological product for plant protection.

Nörogelişimsel Hastalığı Olan Çocuklarda Duyusal İşlem Bozukluklarının Beslenme Davranışına Etkisi: Mini Bir Derleme
Authors: Koç Nevra , Kılıç Fatma , Eroğlu Fatma Elif
Published: June 2024

Çocuklarda yaygın olarak görülen nörogelişimsel hastalıkların önemli semptomlarından birisi de duyusal işlem bozukluğudur. Duyusal işlem bozukluğu, çevresel uyaranlara duyusal olarak yanıt verilmesinde yaşanan aşırı duyarlılık veya kayıtsızlık olarak tanımlanmaktadır. Duyusal işlem bozukluğu özellikle otizm spektrum bozukluğu, dikkat eksikliği ve hiperaktivite bozukluğu gibi nörogelişimsel bozukluklara sahip olan çocukların genel olarak beslenme davranışı ile ilişkilendirilmektedir. Oral, dokunsal ve koku duyularında hipersensitivite/hiposensitivite seçici yeme ve kısıtlı yeme davranışlarının ortaya çıkmasına veya bu davranışların şiddetinin artmasına yol açmaktadır. Seçici yeme davranışı beslenme durumlarını etkileyerek çocuklarda genellikle daha düşük sebze ve meyve, daha fazla doymuş yağ ve basit karbonhidrat tüketimiyle sonuçlanmaktadır. Bu durum çocukların enerji ile makro ve mikro besin ögesi gereksinimlerinin günlük önerilen düzeylerde alınmamasına sebep olmaktadır. Yetersiz ve dengesiz beslenme sonucunda çocuklarda obezite veya malnütrisyon görülebilmektedir. Yapılan son çalışmalarda beslenme davranışını da önemli düzeyde etkileyen duyusal işlem bozuklukları hakkında ebeveynlerin ve sağlık çalışanlarının farkındalığının yeterli düzeyde olmadığı görülmüştür. Nörogelişimsel hastalıkları olan çocuklar beslenme sorunları açısından risk altındadır. Bu bağlamda çocukların beslenme durumu değerlendirilirken duyusal işlem bozukluklarının varlığı, var olan hassasiyet veya kayıtsızlığın besin tüketim durumu üzerindeki etkisi sorgulanmalı ve bu durum çözüm arayışında dikkate alınmalıdır. Bu derlemenin amacı, nörogelişimsel hastalığı olan çocukların duyusal işlem bozuklukları ile ilişkili beslenme davranış sorunlarına dikkat çekerek konuyu güncel literatür ışığında değerlendirmektir.

Published: June 2024

Savaşlar, ulusal ve uluslararası güvenliği etkileyen olaylar olduğu için, haberlerin doğru, tarafsız ve güvenilir olması son derece önemlidir. Bu amaçla çalışmamızda, İsrail ordusunun, Hamas’ın 7 Ekim’de başlattığı saldırıların ardından çatışması ile ilgili yapılan haberlerin dezenformasyon boyutu ortaya koyulmaya çalışılmıştır. Nitel yöntemin uygulandığı çalışmada, Gazze’ye yönelik başlatılan saldırılarla ilgili dezenformasyon faaliyetlerini incelemek için ardışık örnekleme tekniğiyle seçilen 10 örnek analiz edilmiştir. Haberlerin doğruluğu, Anadolu Ajansı (AA) Teyit Hattı, T.C. Cumhurbaşkanlığı İletişim Başkanlığı Dezenformasyonla Mücadele Merkezi ve teyit.org haber sitesi üzerinden incelenerek tespit edilmiştir. Bu anlamda haberlerde ve görsellerde nasıl bir dezenformasyon yapıldığı ve yanlış bilginin hangi yöntemle servis edildiği ortaya koyulmaya çalışılmıştır. İsrail’in medyada yer alan kadınların, bebeklerin öldürülmesi hastanelere, camilere ve kiliselere yönelik saldırılarına karşın çatışmada kendisini haklı göstermek adına bir sürü dezenformasyona başvurduğu tespit edilmiştir. İsrail’in sosyal medya platformları üzerinden hızlı ve kolay erişimle, toplumları çok rahat manipüle edilebildiği belirlenmiştir. Çatışmada en çok yalan haberler yayıldığı gözlenmiştir. Ayrıca çalışmada, çatışma ilgili haberlerinde ve iddialarında gerçekleştirdikleri dezenformasyonla kitlelerin algılarını önemli şekilde etkilemeye çalıştığı belirlenmiştir.

Ekolojik ve ekonomik katkısı yüksek olan sulak alanlar geçmişte önemli alansal kayıplar vermiştir. Son yıllarda korunma çalışmaları artmıştır. Bu çalışma ile Türkiye’deki Ramsar Sözleşmesi (1971) sulak alan tanımına uygun alanların genel değerlendirilmesi yapılmıştır. Ülkemizdeki sayıları, alansal dağılımları, yükselti basamaklarına göre dağılımları vb incelenmiştir. Sulak Alan Bilgi Sisteminde (SAYBİS) 2021 yılı itibariyle kayıtlı 1 159 adeti doğal durgun sulak alan, 78 adeti denizel sulak alan ve 1 357 adeti yapay sulak alan olmak üzere. toplam 2 594 adet sulak alan vardır. Bu alanların toplamı ise 1 491 936 ha’dır. Harita Genel Müdürlüğü (HGM) kayıtlarına göre Türkiye’de toplamda 44 595 adet sulak alan belirlenmiş ve bu alanlar toplam 1 213 830 ha’dır. En fazla sulak alan 0-500 m yükselti basamağındadır. Yine 1 ha’dan küçük sulak alan sayısı diğer alanlara göre fazladır. Sürdürülebilir yönetim için alanların özelliklerinin bilinmesi faydalı olacaktır.

Hammadde tedarikinde ciddi sıkıntı yaşayan kâğıt sektöründe ormanların yanında alternatif kaynaklar konusu ve özellikle atık kağıtların daha verimli işlenmesi üzerine yoğun araştırmalar yapılmaktadır. Son yıllarda kağıtların geri dönüşüme katılım oranlarının artması, kağıt üretim sistemine dahil olan geri dönüştürülmüş kağıtların kullanım miktarlarının artmasına da sebep olmuştur. Bu anlamda artan geri dönüşüm sayısı sonucu elyaf özelliklerindeki düşmelere bağlı olarak çok çeşitli katkı kimyasalları ve dolgu maddeleri kullanımı da doğal olarak artmaktadır. Kağıt üretiminde kullanılan temel maddeler lifsel maddeler, su ve lifsel olmayan yardımcı maddeler olacak şekilde genel bir sınıflandırma yapılabilir. Lifsel olmayan yardımcı maddeler arasında dolgu maddeleri, katkı maddeler, tutundurucu maddeler, su itici ve yanma geciktirici kimyasal maddeler gibi gruplara ayırmak mümkündür. Kağıtta dolgu maddeleri opaklığın artırılmasında, yüzey düzgünlüğünün sağlanmasında, baskı kalitesinin iyileştirilmesi, temini kolay ve ekonomik olması, enerji tasarrufu sağlaması gibi sebeplerinden ötürü kağıt üretiminde sıklıkla tercih edilmektedirler. Yapılan çalışmada Expancel adıyla üretilen bir kimyasal bileşenin kağıt üretiminde bir dolgu maddesi olarak kullanılabilirliği araştırılmıştır. Sonuçlar kağıt sektörü için umut vericidir. Ayrıca elde edilen sonuçlar ışığında Expancel kullanımı ile kağıtlarda hacimsel artış olmuş, kağıtların eğilme(bükülme) değerlerini yükseltmiştir. Expancel katılımı kağıtların hava direncini artırmış, aşırı katılım da ise hava dirençlerinde düşme meydana gelmiştir. Mukavemet değerlerinde ise kısmi bir düşüş olmuştur.

Yonga levha üretiminde levhaların rutubet dayanım özelliklerini iyileştirmek amacıyla parafin emülsiyonu kullanılmaktadır. Parafin endüstriyel yonga levha üretiminde mikser isimli tutkallama makinasında verilmektedir. Bu çalışmada mikser makinasında, veriliş sırasının değiştirilmesinin üretilecek olan yonga levha örneklerinin performans değerlerine etkileri araştırılmıştır. Parafin emülsiyonu, tutkallama öncesi ve sonrası dozajlanmıştır. Yonga levhalar, 18 mm kalınlıkta, 640 kg/m3 yoğunlukta, %32 dış tabaka yonga oranı, %68 orta tabakada yonga oranı olacak şekilde sürekli pres hattında 220 °C sıcaklıkta üretilmiştir. Üretilen levhaların fiziksel özelliklerini belirlemek için su alma ve kalınlığına şişme, mekanik özelliklerini belirlemek için eğilme dayanımı ve yüzeye dik çekme testleri yapılmıştır. Örneklerin formaldehit emisyon değerleri gaz analizi, desikatör ve perfaratör metotları ile incelenmiştir. Elde edilen sonuçlara göre parafinin tutkallama işlemi sonrası sisteme verilmesinin formaldehit emisyonu değerlerini desikatör metoduna göre %9.8, perfaratör metoduna göre %7, gaz analizi metoduna göre %17.2 oranında düşürdüğü ortaya konulmuştur. Yüzeye dik çekme direnci tutkallama öncesi 0,52 N/mm2, tutkallama sonrası 0,50 N7mm2 olarak tespit edilmiştir. Parafinin veriliş sırasının değiştirilmesiyle levhaların fiziksel özellikleri olumsuz etkilenmiştir, ancak mekanik özelliklerde ise önemli bir değişiklik gözlemlenmemiştir.
The competition between the United States and China in the emerging technologies and its implications on the associated national security
Authors: Gawi Yesmin Abubakar , Abdullahi Abdulkarim
Published: June 2024

National security is affected by the competition between the United States and China in emerging technologies. In emerging technologies such as artificial intelligence, 5G telecommunications, and cybersecurity, the stakes are high for both countries. It is imperative that these technologies advance in order to remain competitive economically, maintain military superiority, and ensure national security as a whole. There are potential implications for other nations and international alliances from the rivalry between the United States and China in these areas. Moreover, the outcome of this competition may influence future technological norms and standards, affecting global markets and innovations. To navigate the complex interplay between technology, national security, and global influence, policymakers, businesses, and stakeholders must understand the dynamics of this competition. Adopting a qualitative approach to the study of international relations, the paper adopts a theory of balance of power to the study of international relations, which the idea is to keep things steady and discourage large conflicts from developing. The paper concludes that in order to make sure that cutting-edge technologies are generated and utilized in an ethical and open manner, constructive communication and cooperation between the US and China are necessary as their competition develops. Both states may lessen any security dangers and improve world peace by creating common principles for the moral and safe use of these technologies. Addressing the wide-ranging impacts of this competition on international relations and national security would also involve multilateral collaboration with other key global parties. It is vital that China and the United States actively explore for ways to work together and make a commitment to building an environment of mutual respect and trust in the realm of emerging technologies.

Purpose: This paper examined the impact of Environmental, Social and Governance (ESG) scores of for-profit colleges, universities, and professional schools on their market and financial results. Design/methodology/approach: Sample data from 50 companies, national and international, listed on a stock exchange and with ESG data available from 2012 to 2021 was obtained on the EIKON-REFINITIV information database. Performance variables comprised Tobin’s Q and Market-to-Book (MTB), widely adopted in similar economic studies. Return on Assets (ROA) and Return on Equity (ROE) conformed to the financial performance variables. Explanatory variables consisted of ESG combined, ESG Social Pillar, Environmental Pillar, and Governance Pillar indexes. The analysis used the Generalized Method of Moments regression (GMM). Findings: ESG combined showed a significant positive relationship with Social Pillar scores and financial performance, represented by ROE and ROA, as found by other studies. Conversely, we observed a significant negative relationship between ESG combined and Social Pillar scores and market indicators (Tobin’s Q and MTB). Practical implications: Results indicate that although ESG combined, Social Pillar scores, and financial performance are positively related to financial results, these do not reflect positive market recognition or price shares. Originality: First-time results for this sector.
