Published: April 2023

Big data technology has been widely used in entrepreneurial research in recent years. To explore the development trend and fundamental characteristics of big data in entrepreneurship (BDIE) research, we conduct a comprehensive bibliometric analysis of BDIE based on 541 publications between 1993 and 2020 from Web of Science. On the one hand, this paper focuses on some essential characteristics of the BDIE publications, such as categories, citation, H-index, and the most cited publications. On the other hand, visual scientific maps are presented by bibliometric tools, i.e., Bibliometrix, VOS viewer, and CorTexT Manager, showing relationships between publications and knowledge structure in BDIE research. Finally, hot topics in current studies, knowledge, and limitations are discussed, guiding scholars to explore new research directions. This paper provides a relatively broad perspective for applying BDIE research, which contributes to understanding the evolution of BDIE research and inspires scholars in related fields.

Authors: Noja Gratiela Georgiana , Cristea Mirela , Pirtea Marilen Gabriel , Panait Mirela , Drăcea Raluca Mihaela , Abrudan Denisa
Published: April 2023

Given the sizeable importance of companies from the energy sector, and the economic, social, and environmental implications generated by their activity, an in-depth assessment of the relationship between financial performance and Corporate Social Responsibility (CSR) initiatives becomes essential for this sector. In this paper, we investigate the shaping factors of the financial performance of companies in the energy field, with a particular focus on the renewable energy sector, in a comparative approach with the conventional ones. The data were gathered from the Refinitiv Eikon database. The methodology applied consists of several advanced econometric procedures, namely robust regression and structural equation modelling. Our findings bring to the fore the distinctiveness of the main drivers of financial performance of companies from the renewable energy sector, compared with the conventional ones, for which specific policies and strategies are needed to comply with the CSR dimensions, as predictors of financial performance in the energy sector.
The Quest for Regionalization of Global Value Chains in a Pandemic Global Business Environment
Authors: Sekliuckiene Jurgita , Rybakovas Egidijus
Published: April 2023

Covid - 19 has affected global value chains (GVCs) and firms’ behaviours within GVCs to a large extent. Firms need to find flexible solutions to stabilize production and rethink value chain governance and supplier relationships. Thus, GVCs recover from the initial shock, and the GVCs reconfiguration becomes essential for managers. We reviewed recent literature focusing on the GVCs, the role of governance and Covid – 19 effects on it as well as the regionalization trend. Thus, this study aims to give empirical evidence on the reconfiguration of GVCs, particularly the changes in the structure of suppliers in the global apparel industry, by using the Bloomberg Supply Chain Analysis tool in the period of 2017-2021. We analysed the structural changes in selected leading apparel multinational companies’ GVCs - Industria de Diseno Textil, S.A. (Inditex), Hennes &Mauritz AB (H & M) and adidas AG. The findings provide insights on the current state of the theoretically discussed and widely expected regionalization trend in GVCs. The study concludes that two out of three cases provide evidence indicating an ongoing trend toward GVCs regionalization. The contribution of this study consists of empirical evidence of the changes in GVCs supplier structure in the apparel industry in response to pandemic global business environment. Practical implications and recommendations for businesses and policy makers are related to the revealed theories and testable models by using Bloomberg’s Supply Chain Analysis data and linking causes and effects of the GVCs regionalization processes.
Diversity Management und Interkulturalität
Authors: Ilseven Bugrahan
Published: April 2023

Many companies and organisations advertise with diversity and diversity management and present it as a socio-theoretical and political concept for the future. In this way, economic and social problems are to be overcome and inclusion advanced. Bugrahan Ilseven critically analyses the question of how and under what conditions diversity management shapes pluralistic societies in an inclusive and integrating way. He also asks what contribution interculturality and intercultural competences can make to making late-modern societies inclusive. He does this by analysing the concepts of diversity management in the "Ford-Werke GmbH Köln", the Bundeswehr and in the school system.
An Ethic of Abolition
Authors: Robert Nikia S. ,   Philosophy Documentation Center
Published: April 2023

This paper addresses the uncanny resemblance between the educational industrial complex and the US carceral state. Both schools and prisons comprise carceral apparatuses that use policies, pedagogies, and practices to respond punitively to com­munal transgressions. Moreover, architectural designs and fiscal budgets further reveal symmetries that make learning communities unsafe and complicit with carceral systems. Black and Brown people are disproportionately caught in the frays of punitive disparities, targeted violence, and stereotypes of deviance that drastically impede social thriving. Ergo, this paper responds to the inextricability of punishment that link classrooms to prisons by introducing an abolitionist theological ethic to create educational sanctuaries.
Cenozoic diversity and distribution of the mangrove-and mudflat-associated gastropod genus Terebralia Swainson, 1840 (Potamididae: Caenogastropoda) in Europe
Authors: THIVAIOU Danae , HARZHAUSER Mathias , KOSKERIDOU Efterpi
Published: April 2023

We analyse the distribution of the potamidid genus Terebralia Swainson, 1840 in the European fossil record (middle Eocene to Miocene). Extant Terebralia contains species restricted to mangroves and mudflats, rendering it a reliable element for detecting these coastal environments in the fossil record. Our contribution summarizes the European fossil record of this taxon and highlights the presence of this genus within coastal environments in the European realm. Distribution in the Cenozoic is interpreted based on ecological preferences, dispersal modes and climatic restrictions of recent species. Maximum geographical distribution is reached during the Early and Middle Miocene with two species being present from the southernmost parts of Europe and Anatolia to the North Sea Basin and the Paratethys. During the Late Miocene, the distribution of Terebralia lignitarum (Eichwald, 1830) is patchy and limited to the South of Europe. The Messinian Salinity Crisis coupled with a changing climate caused the disappearance of Terebralia in the Mediterranean first, and then marked the end of mangrove environments in this province.
Analysis of the Application of Relaxation Therapy on Chronic Pain Problems in the Elderly with Hypertension at UPT PSTW Jember
Authors: Daniela Andrena  , Kurdi Fahruddin
Published: April 2023

The elderly are over 60 and experience physical, mental, and social changes. A decrease in physical strength, endurance, and appearance indicates physical changes in the elderly. The elderly are at risk of experiencing hypertension due to several factors, decreased elasticity and accumulation of collagen in the aortic wall, neurotransmitter imbalance due to depression, and an unhealthy lifestyle during youth. This study aims to determine the impact of applying relaxation therapy to chronic pain problems in the elderly. The design of this case study is descriptive qualitative with a nursing care process approach. This study took a sample of Mr. M, who has chronic pain problems with hypertension at UPT PSTW Jember. This research was carried out for seven days with the application of therapy for six days on December 4-10 2022. Data collection was carried out using interviews and observation. The evaluation of this intervention therapy action uses the NRS pain scale, blood pressure measurement, and pulse count. Relaxation therapy using the spiritual-emotional freedom technique (SEFT) has made a difference in chronic pain problems in the elderly with hypertension. This is evidenced by decreased pain scale and blood pressure after therapy.
Financial literacy of Portuguese undergraduate students in polytechnics: does the area of the course influence financial literacy?
Authors: Sarabando Paula , Matias Roge rio , Vasconcelos Pedro , Miguel Tiago
Published: April 2023

Financial literacy seems to be more important and focused than ever. Several recent studies have found that Portugal is at bottom of the table compared to the Eurozone countries regarding financial literacy. As it’s a key factor in the development of a country, it appears to be crucial to understand what people know about financial matters when they complete compulsory schooling. With a sample of 296 Portuguese students who enrolled in the polytechnic higher education system for the first time, we studied if they understand simple concepts related to financial issues (such as loans), as well as whether they are aware of the risk of not recovering the money invested that is embedded in some of the most talked-about and common financial products that are available in the market. This last objective seems to be relevant since a lot of fraudulent schemes involving teenagers, young adults, and financial markets have emerged in recent years. From the results, some disturbing conclusions can be drawn. For instance, more than two-thirds of the sample do not know what Euribor is (similar result regarding Spread). About a third of the simple do not understand inflation’s consequences. 16,9% do not know what term deposits are, and derivative products and saving certificates are seen as very alike regarding the risk they represent. Students who chose a business-related course as their first choice when applying showed a higher level of financial literacy, although it is still low compared to what one would expect.

Area Estimation of Mango and Coconut Crops using Machine Learning in Hesaraghatta Hobli of Bengaluru Urban District, Karnataka
Authors: Ahmed Zubair , Nageswara Rao P.P. , Srikanth P.
Published: April 2023

Timely and accurate estimation of acreage and production of horticulture crops is necessary for deciding how much, where and when to export these commodities in the national and global markets. Remote sensing has been one of the methods adopted, in addition to conventional sampling methods, for improving the estimates. Parametric image classification algorithms have been used by many researchers for identification and area estimation of horticulture crops. But these algorithms result in several unclassified pixels leading to over/underestimates. This study has been undertaken to estimate the area of two horticulture crops (i.e., mango and coconut) of Hesaraghatta hobli of Bengaluru urban district using Convolutional Neural Network (CNN) on Google Colaband Random Forest (RF) algorithms on Google Earth Engine (GEE). Remotely sensed data acquired by the Multi-Spectral Instrument (MSI) onboard Sentiel-2A satellite was used. Spectral signatures of horticulture crops and other associated cover types have been generated to identify the cover types and for selecting appropriate band combinations. Two different band combinations were used for area estimation of selected horticulture crops: i) Near-InfraRed (NIR), Red, and Green all three having a spatial resolution of 10 m, ii) Red edge-3, Short-Wave InfraRed1 (SWIR1) and Short-Wave InfraRed2 (SWIR2) having 20 m spatial resolution. Area estimates of horticulture crops and associated cover types were validated with respect to ground truth and statistical reports from Karnataka State Directorate of Horticulture (KSDH). It was found that the CNN model performed better than RF using NIR, Red, and Green band combination with an overall accuracy of 84%, but it failed to give similar accuracies with Red edge 3, SWIR1, and SWIR2 band combination. We attempted transfer learning using the trained CNN model at two different study areas far away from the study area and found encouraging results.

The objective: to determine the indications and possibility of surgical treatment of giant malignant intrathoracic tumors.

Subjects and Methods. The authors presents their own experience of treatment of 19 patients with giant malignant intrathoracic tumors.

Results. Overall resectability was 79% (15/19 patients). 4 patients underwent combined surgery: in 2 patients, the tumor was removed with resection of a part of the upper lobe of the lung; 1 patient had this left lung resected (pneumoectomy); and 1 patient had type A thymoma, so resection and reconstruction of the pulmonary arterial trunk was performed. Radicality was assessed both during surgery (R2 – in 3 patients) and during morphological testing of surgical specimens (R1 – in 1 patient).

Among the operated giant neoplasms of the chest, which did not include lymphomas and extra-gonadal dysgerminogenic tumors, thymoma (7/19; 36.8%) and neoplasms of neurogenic origin (3/19; 31.6%) of varying degrees of differentiation were more often diagnosed.

The examination algorithm of these patients and decision-making on surgical tactics are presented. The article discusses access options and technical surgical methods for removing large tumor masses with a specific clinical examples.

The objective: to assess risk factors for tuberculosis relapse during the COVID-19 pandemic.

Results. During the retrospective study, medical documents of patients treated for tuberculosis in 2020-2022 were analyzed. 140 patients above 18 years old with confirmed tuberculosis were included: newly diagnosed tuberculosis – 50 patients, early relapses – 50 patients, and late relapses – 40 patients. At the first stage, significant factors for relapse development were identified (ANOVA): diabetes (F=19402,8; p=0,000000), substances abuse (F=547,6; p=0,000000), alcohol abuse (F=149,7; p=0,000000), MDR MTB (F=107,8; p=0,000000), HIV infection (F=72,4; p=0,000000), imprisonment (F=49,5; p=0,000000), chronic respiratory diseases (F=47,1; p=0,000000), smoking (F=29,0; p=0,000000), and social status (F=28,9; p= 0,000000). At the second stage (cluster analysis), factors implementing the risks of development of early or late relapses were identified.

As well as before the COVID-19 pandemic, social, medical and biological risk factors play a significant role in the development of tuberculosis relapses; history of COVID-19 was not one of the risk factors; and stratification of the risk factors made it possible to identify factors that contribute to development of both early and late relapses and to determine preventive measures.

Authors: LALE Aybala , KARABULUT Bilal
Published: April 2023

The fact that the production and management of information is one of the most remarkable means of obtaining power has disclosed the concept of propaganda is especially crucial for authoritarian states. In this framework, The North Korea, as an authoritarian country without freedom of the press, seized the power of information and adopted various propaganda methods. Trying to adapt to digital transformations, the North Korea has benefited from the internet as a propaganda tool. Naturally, this brings along the digitalisation of propaganda. This article scrutinises the North Korea's digital propaganda and strategic communication methods through a critical discourse analysis of four North Korean news texts. The method of the article was determined based on Teun A. van Dijk's news discourse analysis. In this context, it has been tried to reveal whether there is a relationship between the concepts of propaganda and strategic communication. Besides the discursive changes of the propaganda contents depending on the period have been discussed. The claim that the critical discourse analysis has the authority-power relationship and the reflections of this relationship on discourse have been supported by the North Korean propaganda.

Published: April 2023

Damgalama, itibarsızlaştırma ya da istenmeyen belirti olarak tanımlanmaktadır. Sosyal kimlik tehdidi ise kişisel bir özellik olarak incelenen sosyal kimlik karmaşıklığının yanı sıra hem bireysel özelliklerden hem de çevresel unsurlardan etkilenen bir olgu olarak ifade edilmektedir. Bu çalışmada Türk ve Arnavut toplumlarının indirimli mağazalardan alışveriş davranışında sosyal damgalama ve sosyal kimlik tehdidi itibariyle incelenmesi amaçlanmaktadır. Çalışma kapsamında sosyal damgalama ölçeği ve sosyal kimlik tehdidi ölçeği kullanılarak toplamda 16 soruluk bir anket formu hazırlanmış olup; eğitim durumları, aile toplam gelirleri, cinsiyetleri ve yaşları ile ilgili demografik sorular sorulmuştur. İlgili ülkelerde gönüllü olarak katılım sağlayacak kişilerin desteğiyle, Google form aracılığıyla anket uygulaması yapılmıştır. Uygulanan ankette tüm parametreler incelendiğinde iki ülke arasında istatistiki anlamda farklılık olduğu belirlenmiştir. Tüm bulgular ve değerlendirmeler neticesinde indirimli mağazalarda sosyal damgalama ve sosyal kimlik tehdidine yönelik ülkeler bazında yeni yapılacak olan çalışmalarda farklı sosyal, psikografik ve psikolojik faktörlerin yanı sıra farklı sosyo-ekonomik verilerin üzerinde durularak daha kapsamlı bir profil elde edilebileceği düşünülmektedir.

Gelişmeleri kaçırma korkusu (FoMO) ve sosyotelizm davranışı bireyin sosyal ilişkilerini, iş performansını ve genel yaşam kalitesini olumsuz yönde etkileyen psikolojik unsurlardan bazılarıdır. Alan yazınında, olumsuz bir duygu durumu olan FoMO’nun sosyotelizm davranışıyla ilişkili olabileceğine dair bulgular yer almaktadır. Bu çalışmanın amaçlarından ilki FoMO, problemli sosyal medya kullanımı ve sosyotelizm davranışı arasındaki ilişkileri incelemektir. Çalışmanın ikinci amacı ise FoMO ve sosyotelizm davranışı arasındaki ilişkide problemli sosyal medya kullanımının aracılık rolünü incelemektir. Bu kapsamda çalışmanın örneklemi, İsveç’in Göteborg Üniversitesi’nde öğrenim gören toplam 451 (217 (%48.1) kadın, 234 (%51.9) erkek) üniversite öğrencisinden oluşmaktadır. Çalışma kapsamına dahil olan öğrencilere yüz yüze anket uygulanmıştır. Gelişmeleri Kaçırma Korkusu (FoMO) Ölçeği, Problemli Sosyal Medya Kullanım Ölçeği ve Sosyotelizm Davranışı Ölçeği veri toplama araçları olarak kullanılmıştır. Bulgular, FoMO’nun ve problemli sosyal medya kullanımının sosyotelizm davranışını anlamlı olarak yordadığını göstermiştir. Ayrıca, FoMO’nun sosyotelizm davranışının alt boyutu olan telefon tutkusuna olan etkisinde problemli sosyal medya kullanımının aracı rolüne sahip olduğu bulunurken FoMO’nun sosyotelizm davranışının bir diğer alt boyutu olan iletişim bozukluğuna olan etkisinde problemli sosyal medya kullanımının aracı rolü bulunmamıştır. Bu kapsamda, elde edilen bulguların hem alan yazınına hem de pratiğe önemli katkılar sunacağı düşünülmektedir.

The potential advantage of the Trading Village can be seen from the abundant vegetable harvest. The majority of the villagers work as vegetable farmers. This is certainly a distinctive feature for a village. However, in living life, there are often old problems, namely the loss of local farmers due to harvests that are not always sold perfectly. Vegetables that do not last long and rot end up dumping organic waste into rivers. The existence of this activity in addition to harming the farmers also causes environmental problems that are polluted due to organic waste. Seeing this problem, the researcher took the initiative to find a solution in the form of cultivating Maggot Black Soldier Fly, which has the opportunity to create a new business worth rupiah and is useful in creating a healthy environment and avoiding disease. Meanwhile, the research method starts from the preparation stage where researchers conduct site surveys, interviews, and observations. Then it was continued at the implementation stage, namely the Maggot Black Soldier Fly cultivation process and ended in the mentoring stage, where the researchers held a workshop on Maggot cultivation tips as an effort to change the mindset of the Merchant Village community. In addition, the researchers also cooperated with the youth of the trading village to participate and care to deal with the problem of village organic waste

Allergic rhinitis and its influence on the development of mouth breathing and temporomandibular dysfunction (TMD) in children from Río Negro, Argentina
Authors: Mulbany Patricia E. , Giraud-Billoud Maximiliano
Published: April 2023

Background: Temporomandibular dysfunction (TMD) is a pathological entity related to functional problems of the joint and/or masticatory muscles. This entity is a public health problem studied for a long time, seeking to identify, among other characteristics, early identification strategies in order to reduce its chronic consequences. Aim: The aim of this study was to describe the results obtained in clinical dental and morphometric evaluations that can be routinely performed in a dental office, in order to verify if these allow an early diagnosis in children and adolescents with probable TMD. Methods: An observational, longitudinal and prospective study was carried out evaluating 36 mouth breathing patients aged 7-14 years, divided into two equal groups according to whether or not they had allergic rhinitis. DTM was studied by means of validated questionnaires and clinical tests, together with morphometric parameters calculated on radiographic images. Results: Tests and mouth breathing questionnaire showed significant differences between both groups. All the children in the control group had a mild disorder, while in the case group the totality was distributed between moderate (89%) and severe (11%) disorders. The movement indicator (Manglione index) showed that 83% of the patients in the control group were moderately impaired and 17% were severely impaired, while 100% of the patients in the case group were severely impaired at the time of consultation. The results of the morphometric analysis of the panoramic radiographs indicated that all patients with mouth breathing, whether due to allergic rhinitis or another cause, present differences in reference to condyle, ramus, body and ramus width symmetry between left and right side of the face in linear and angular measurements, with only the Condilion to Gnation distance being significantly lower in the cases. Conclusions: The diagnosis of DTM requires an oriented clinical examination to assess functional limitation. In addition, a complementary imaging study of low complexity such as panoramic radiography can allow visualization of changes such as the presence of osteophytes, which provide clarity to the diagnosis, given that pediatric patients do not always present the signs and symptoms classically described for adult patients.

Published: April 2023

In view of the widespread increase in herbicide-resistant weeds, biotechnology companies have developed dicamba-tolerant soybean and cotton cultivars. This technology can, however, increase the risk of the product drifting to adjacent areas. This study was developed with the objective of the to evaluate the phytotoxicity and biometric variables of young eucalyptus plants exposed to subdoses of the herbicide dicamba. The experiment was carried out under field conditions in Rio Verde, state of Goiás, Brazil. The treatments were represented by the application of 0 (control), 7.5, 15, 30, 60, 120 or 240 g ae ha-1 of dicamba 45 days after the seedlings were planted in the field. In terms of phytotoxicity, the dicamba doses of 120 and 240 g ae ha-1 caused greater damage to the eucalyptus plants in all periods of evaluation. The predominant symptoms were epinasty, increased number of shoots and necrosis and senescence of young branches and leaves. The herbicide doses of 120 and 240 g ae ha-1 significantly compromised plant height and diameter, number of branches and dry mass of leaves and roots, interfering with the growth and development of the eucalyptus crop. The results indicate that the effect of subdoses of the herbicide dicamba can interfere with the proper development of young eucalyptus plants, which may cause losses in the initial planting phase and future losses for producers.

A mancha de alternária é uma das principais doenças da canola, reportada nas regiões produtoras da oleaginosa. Objetivou-se investigar se o espaçamento de semeadura em canola combinado com a aplicação de fungicidas produz efeito sobre os danos causados pela mancha de Alternária e como estes se refletem sobre o rendimento da cultura. O híbrido estudado foi o ‘Nuola 300’ e o delineamento experimental utilizado foi o de blocos ao acaso, em esquema de parcelas subdivididas, com quatro repetições. Nas parcelas principais foram dispostos os espaçamentos entre linhas (17 cm e 50 cm) e, nas subparcelas as aplicações de fungicidas (T1 - testemunha sem fungicida; T2 - azoxistrobina + tebuconazol, no estádio B4; T3 - azoxistrobina + tebuconazol, em B4 e piraclostrobina + fluxapiroxade, em B4 + 15 dias; T4 - piraclostrobina + fluxapiroxade, no estádio B4 + 15 dias). Nas condições de condução desse experimento, na região de Erechim – RS, houve controle da mancha de alternária em folhas e síliquas de canola com a aplicação dos fungicidas azoxistrobina + tebuconazol e piraclostrobina + fluxapiroxade, sendo que o melhor controle em síliquas foi obtido no espaçamento de 17 cm entre linhas. O tratamento com piraclostrobina + fluxapiroxade no espaçamento de 50 cm entre linhas apresentou maior número de síliquas por plantas, bem como maior produtividade.
