Authors: Yasar Erdogan , Erdal Huseyin , Tuncer Sibel Cigdem , Yagcı Betul Akbulut
Published: December 2023

Purpose:

The present study aimed to investigate the value of calprotectin and other inflammatory parameters in patients with glaucoma and systemic diseases accompanying pseudoexfoliation syndrome (PEX-S).

Methods:

This prospective study included 45 PEX-S patients and 45 non-PEX control patients. Patients were investigated for the presence of glaucoma, cardiovascular disease (CVD), ischemic brain disease (IBD), Alzheimer’s disease, and neurosensory hearing loss (NSHL). After excluding diseases that may affect inflammatory parameters, a detailed biomicroscopic examination, and blood tests were performed for the patients.

Results:

Glaucoma, CVD, NVK, Alzheimer’s disease, and NSHL were high in the PEX-S group (P = 0.01, P = 0.01, P = 0.04, P = 0.04, and P = 0.03, respectively). Calprotectin, ferritin, neutrophil-to-platelet ratio, and lymphocyte-to-platelet ratio were found to be high in the PEX-S group (P < 0.01, P = 0.04, P < 0.01, and P < 0.01, respectively). On evaluating the relationship between PEX-S and glaucoma and systemic diseases, it was found that elevated calprotectin increased the risk of glaucoma by 4.36 times and elevated neutrophil-to-lymphocyte ratio (NLR) increased the risk of CVD by 3.23 times in PEX-S patients (P = 0.02 and P = 0.03, respectively).

Conclusion:

This study demonstrated the value of calprotectin elevation in detecting concomitant glaucoma in PEX-S patients and, in addition, the value of NLR elevation in detecting concomitant CVD.

Published: December 2023

Malignancy of the external auditory canal (EAC) is rare, and adenoid cystic carcinoma (ACC) of EAC is even rarer. It is generally managed by radical resection with a clear oncological margin, followed by radiotherapy. However, local recurrence and distant metastasis are still the major concerns during follow-up. The authors present a case in a 32-year-old female, presenting with a mass in the EAC which was endoscopically removed. Histopathological examination revealed an ACC. Further imaging confirmed absence of distant metastasis and parotid gland involvement. The patient was treated with right modified lateral temporal bone resection and achieved clear surgical margins and thus planned for a long-term follow-up.

Published: December 2023

Objective:

There are a limited number of studies on Acoustic reflex latency (ARL) test in the literature. In this study, we aimed to examine the ARL test results and parameters in young adults in Türkiye and evaluate the difference in interaural latency.

Materials and Methods:

A total of 50 individuals with normal-hearing thresholds, 25 females and 25 males, between the ages of 18 and 35 years were included in the study. Parameters of ARL; 10% – on latency, 90% – on latency, 10% – off latency, and 90% – off latency were recorded and analyzed in 500, 1000, 2000, and 4000 Hz frequencies. Study results were compared between ears and genders.

Results:

When comparing the right and left ears, ARL parameter values of men and women, 90% on and 10% off latency on the right and 90% on latency on the left ear, were found to be longer in women only at a frequency of 4000 Hz. At 500, 1000, and 2000 frequencies, no significant difference was observed between the genders. There was no interaural difference of ARL. As the frequency increased, it was observed that the ARL onset latencies were prolonged in both men and women.

Conclusion:

Our study indicated that there was no interaural difference of ARL in normal-hearing subjects. İnteraural difference of ARL may provide diagnostic information clinically.
Energizing Tomorrow: Analyzing the Transformative Potential of Electric Vehicle Adoption
Authors: Seth Neha , Siddiqui Saif , Asif PC Muhammed , Agnihotri Anu , Gupta Muskan
Published: December 2023

INTRODUCTION: A developing economy lacks the infrastructure required to produce renewable energy sources on a large scale that can be coupled with conventional resources. This prevents the economy from taking advantage of these types of resources. The emergence of the electric vehicles (EVs) industry has been a primary catalyst for both the expansion of the economy and the production of new employment opportunities. The manufacturing and distribution of electronic automobiles have cleared the way for the construction of new manufacturing locations as well as a supply chain. This has been made possible as a result of the increased demand for EVs.
OBJECTIVES: The objectives of this article are to know the overall impact of EVs on the environment through a review of the literature and to study if ongoing changes affect the economy of India.
METHODS: The systematic review of literature is used to fulfil the objectives of the study.
RESULTS: EVs offer a solution to reducing air pollution and greenhouse gas emissions due to their zero tailpipe emissions. They eliminate pollutants like nitrogen oxide and particulate matter, improving air quality and public health. EVs, powered by renewable energy sources like solar, wind, or hydroelectric power, reduce reliance on fossil fuels. Their higher energy efficiency and technological advancements in batteries also create employment and innovative economic opportunities. Additionally, EVs contribute to quieter and more serene environments, especially in densely populated areas, due to their silent operation.
CONCLUSION: It can be concluded that the adoption of EVs has both positive and negative impacts on economy countries. But as compared to negative impacts, positive impacts are very high on the economic condition of any country.

Authors: Zhang Jing-Chao , Ma Yang-Yang , Lan Yong-Zhen , Li Shuang-Biao , Wang Xiao , Hu Jin-Long
Published: December 2023

BACKGROUND

Preoperative diagnosis of appendiceal mucinous neoplasms is challenging, and there are few reports regarding the endosonographic characteristics of these neoplasms.

AIM

To provide a retrospective assessment of the imaging features of appendiceal mucinous neoplasms using endoscopic ultrasound (EUS) by curved linear-array echoendoscope.

METHODS

A database of all patients with appendiceal mucinous neoplasms who had received EUS examination at our hospital between January 2018 and July 2023 was retrospectively analyzed. The EUS characteristics and patients’ clinical data were reviewed.

RESULTS

Twenty-two patients were included in the study. The linear-array echoendoscope successfully reached the ileocecal region in every patient. In the endoscopic view, we could observe the protrusion in the appendiceal orifice in all patients. A volcano sign was observed in two patients, and an atypical volcano sign was seen in two patients. EUS showed that all 22 lesions were submucosal cystic hypoechoic lesions with clear boundaries. No wall nodules were observed, but an onion-peeling sign was observed in 17 cases.

CONCLUSION

Linear-array echoendoscope is safe to reach the ileocecal region under the guidance of EUS. Image features on endoscopic and echoendosonograhic views could be used to diagnose appendiceal mucinous neoplasms.

Published: December 2023

BACKGROUND

Esophageal carcinoma presents as 2 types, esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC) with the frequency of both changing in the United States (US).

AIM

To investigate EAC/ESCC incidence time trends among the 3 main US racial groups and investigate trends in US EAC survival by ethnicity.

METHODS

Twenty-five years (1992-2016) of data from SEER 13 program was analyzed to compare incidence trends in EAC and ESCC between non-Hispanic whites (nHW), non-Hispanic Blacks (nHB) and Hispanics (Hisp) using SEERStat® . In addition, SEER 18 data, from 1975-2015, on EAC in the US was analyzed to evaluate racial disparities in incidence and survival using SEERStat® and Ederer II method.

RESULTS

In the 3 major US ethnic groups, age-adjusted incidence of ESCC has declined while EAC has continued to rise from 1992-2016. Of note, in Hisp, the EAC incidence rate increased while ESCC decreased from 1992 to 2016, resulting in EAC as the predominant esophageal cancer subtype in this group since 2011, joining nHW. Furthermore, although ESCC remains the predominant tumor in nHB, the difference between ESCC and EAC has narrowed dramatically over 25 years. EAC survival probabilities were worse in all minority groups compared to nHw.

CONCLUSION

Hisp have joined nHW as US ethnic groups more likely to have EAC than ESCC. Of note, EAC incidence in nHB is increasing at the highest rate nationally. Despite lower EAC incidence in all minority groups compared to nHW, these populations have decreased survival compared to nHW.
Dialectal variation in lexical borrowings in Dangme

Published: December 2023

language spoken in Southern Ghana. Dangme has seven dialects (Ada, Gbugblaa, Yilɔ Krobo, Manya Krobo, Nugo, Sɛ and Osudoku), but this study concerns lexical borrowings into the first four. The language is in contact with four languages from which it has borrowed: Ewe, Ga, Akan, and English. Each dialect of Dangme is in direct contact with English, the official language of Ghana, and with at least one of the three Ghanaian languages. While Ada is in contact with Ewe and Gbugblaa with Ga, both Yilɔ Krobo and Manya Krobo are in contact with Akan and, to some extent, Ewe. The study departed from focus on phonological adaptation of borrowed words, the subject matter of previous studies, to pursue two interrelated objectives, i.e., to find out: (i) whether, and to what extent, borrowings into a dialect from a given source language remain localized or are transferred to the other dialects and (ii) whether, and what extent, the lexical borrowings constitute additions to the Dangme lexicon or, conversely, a relexification of native words in the lexicon. Eighty (80) respondents, 20 each from the four dialects considered, were purposively sampled to participate in the data collection process and the data analysis was done within the Variationist Sociolinguistics Theory. It was found that while most Akan and English lexical borrowings have become integrated in all the four dialects of Dangme, this is not the case with lexical borrowings from Ga and Ewe. Most Ga borrowings are found only in Gbugblaa and most Ewe borrowings are found only in Ada and, to some extent, Manya Krobo. It was also found that Akan and English lexical borrowings generally constitute additions to the Dangme lexicon while Ewe and Ga lexical borrowings may be seen as subtractive borrowings or cases of relexification in Ada and Gbugblaa respectively. The study is expected to contribute to an understanding of how languages like Dangme whose dialects have geographical contact with different languages develop dialectal variation.
Serial verb reduplication in the Mabia languages of West Africa
Authors: Bodomo Adams , Abubakari Hasiyatu
Published: December 2023

This paper introduces and discusses the notion of Serial Verb Reduplication (SVR) in two Mabia languages of West Africa, Dagaare and Kusaal. The authors show that the phenomenon of SVRs, though under-represented in the literature, has a wide scope occurrence in natural language usage within serializing languages. Theoretically, two lexical semantic notions: semantics of verbs (verb meaning) and pluraction, are advanced to explain the intricacies of the syntax and semantics of SVRs. The paper identifies two groups of SVRs: canonical SVRs and pluractional SVRs and proposes that semantically bleached verbs can only be reduplicated in pluractional benefactive and causative SVRs in these languages.
Are we still Shona? An AOTS framework approach to navigating immigration-related identity
Authors: Osei-Tutu Araba Ayiaba Ziekpor
Published: December 2023

Using the African Oral Traditional Storytelling (AOTS) Framework as a culturally centered and responsive storytelling approach to studying with African peoples, this article shares the experiences of a Shona family in the United States of America as they navigate the maintenance and/or retention of their native language and culture as well as transmitting these to their children. Thus, using storytelling as analysis and theory, this article contributes to the discourse on African immigrant identity conceptualization and reconceptualization through a decolonial lens with the aim of encouraging conversations on the gradual linguistic and cultural genocide that continues to plague Africans as we critically wrestle with the lingering effects of colonialism and the lure of global mobility.

Serbian-Albanian coexistence in Kosovo in 1878–1912: the example of the Ottoman State Education System

The principle of equality proclaimed by the Edict of Gulhane (tur. Gülhane Hatt-ı Şerîf) in 1839 resulted in many changes in the socio-political sphere of the Ottoman society, but also with several legal acts regarding education issued by the Ottoman authorities. The Constitution of the Ottoman Empire from 1876 proclaimed equality between all citizens of the state regardless of ethnicity and religion. Even though, relations between the Albanian and Serbian populations in the Kosovo Vilayet were tense in all aspects of socio-political spheres. The representatives of Albanians, as a majority in the vilayet, defended the status of Islam as a dominant religion and Christianity as a religion of slaves (rayah). As the Ottoman authorities issued many legal acts regarding formal basic education in Islamic primary schools (mekteb) during the second half of the 19th century, tensions and misunderstandings between the Serbian and Albanian populations increased. This paper analyzes relations between Serbs and Albanians in the Vilayet of Kosovo in 1878–1912 in the area of implementation of the right to primary education for both communities as this issue has not been researched in detail until now. Our research is based on interdisciplinary approach to the subject and the use of primary archival sources of the Ottoman and Serbian provenance, as well as the relevant literature.

The Agrarian Reforms in Serbia and Bulgaria in 1880 and Their Impact on the Muslim Great Estates – A Comparative Outline

With the fall of the sultan’s rule in the Balkans, the natural aspiration of the rural population was to take control over the lands belonging to the great Muslim landowners – in the case of Bulgarians and Serbs, the agricultural reforms implemented in 1880 became the fulfilment of these expectations. The comparative method was used to formulate the new conclusions on the property relations in these two South Slavic countries at the end of the 19th century, provide an indication of the characteristics of the Serbian and Bulgarian villages as well as to highlight the common features of both countries. An attempt will be made to define the factors that could have contributed to these differences and similarities.

The Socio-Economic Consequences of the Forced Assimilation of Bulgarian Muslims in the Second Half of the 20th Century

In research on the forced assimilation in communist Bulgaria, the attention is most frequently paid to the effects of this process in the context of violating fundamental human and civil rights. However, researchers often overlook the socio-economic consequences of the actions taken at that time. The forced assimilation of Bulgarian Muslims, who chose to leave Bulgaria, resulted in a huge economic loss. The unexpected staff shortage has caused problems for the Bulgarian economy on a massive scale. The change in the organization of work has created tensions in the inter-ethnic relations. The aim of this article is to answer the question – did the economic and social consequences of the so-called Revival Process in Bulgaria led to the collapse of Todor Zhivkov’s regime in the late 1980s?
Combating Illicit Trade in Cultural Objects in the Staatliche Museen zu Berlin (State Museums in Berlin): Policies in Acquisitions and Loans and Research of Provenance
Authors: Winter Petra , Dietrich Florentine
Published: December 2023

In March 2018 the Staatliche Museen zu Berlin-Preußischer Kulturbesitz (State Museums in Berlin) received a significant bequest from the estate of art historian Barbara Göpel (1922-2017), consisting of two paintings, 46 drawings, and 52 prints by Max Beckmann (1884-1950) and one painting by Hans Purrmann (1880-1966). This bequest represents an important addition to the collection of classical modernist works in the Nationalgalerie (National Gallery) and the Kupferstichkabinett (Museum of Prints and Drawings). In 1937 – during the time of National Socialism – the Nationalgalerie lost 505 artefacts as a result of the confiscation of “degenerate art”, among them eight works of Beckmann, who was in those times classified as a “degenerate artist”. But from whom did the Staatliche Museen zu Berlin receive this bequest? And is it generally important to ask from whom a museum receives an artefact? Where did the artworks come from? Is their provenance “clean” in the sense of the 1998 Washington Conference Principles on Nazi-Confiscated Art? Is it legitimate to make a distinction between the person of the collector/estate and the works of art? These are some of the – legal but also moral – questions a museum must address before accepting any cultural object that belonged to a collector who was actively working for a gigantic project like the “Führermuseum Linz”. Or should rejection of the bequest be considered?

Published: December 2023

Cultural Heritage Management (CHM) is the main vehicle for helping museums to face challenges, secure sustainable competitiveness, and redefine themselves in a constantly changing world. In this context, CHM can support museums in their efforts to play a vital role in fighting the illicit trafficking of cultural property. This article focuses on how museums can benefit from the various advantages offered by CHM, specifically with respect to the fight against the illicit trade of cultural property and its return and restitution to its countries of origin. In this light, it deals with both proactive and repressive policies, discussing how museums can maintain their credibility and ensure that they operate in accordance with high legal and ethical standards. Finally, the article discusses how museums and countries have dealt with return and restitution claims in recent years. In this context the use of cutting-edge technologies, such as 3D printing, is also discussed. This work derives from the research project “Redefining the future of cultural heritage, through a disruptive model of sustainability” (ReInHerit), which has received funding from the European Union’s Horizon 2020 research and innovation programme.
Intangible Cultural Heritage Protection and Nigeria’s Heritage Legislation
Authors: Nomishan Terngu Sylvanus , Sule Sani Abubakar
Published: December 2023

This article focuses on the legal and technical challenges of protecting intangible cultural heritage in Nigeria. Over time, Nigeria and its population have focused heavily on the petroleum industry as the primary source of the country’s economic sustainability, ignoring other viable economic sectors such as heritage preservation, protection, and management for sustainable tourism. This is because the country’s heritage legislation has been severely eroded and rendered ineffectual in protecting Nigeria’s heritage resources, in particular its intangible cultural heritage. Various stakeholders have expressed concern about the need to maintain and protect cultural assets all around the world. This has thus led to the promulgation of laws governing their protection. These regulations, however, did not begin in Nigeria until the colonial period, when the necessity to acquire and conserve heritage objects became recognized. Therefore, this article uses an exploratory research design with key informant interview methodologies as a data-gathering instrument. As a result, it demonstrates that numerous intangible cultural heritage resources in Nigeria are negatively impacted by political and societal instability, the increasing demand for antiquities and artworks, and socioeconomic challenges, amongst other human-induced factors. The existing heritage law in Nigeria, Decree No. 77 of 1979, is insufficient in terms of currency, enforcement, and efficiency, rendering its provisions ineffective.
Illicit Trade in Cultural Objects under the Spanish Law: The Cabeza de mujer joven Case
Authors: Capote Pérez Luis Javier
Published: December 2023

This article seeks to introduce a brief description of the rules of protection of cultural heritage goods in the Spanish Law, using the example of a mediatic case of illicit trade, where the regulations of civil law, criminal law, and administrative law were applied and where the freedoms inherent in the right of ownership collided with the rules on properties of cultural interest. First, it provides an overview of the Spanish cultural heritage law, beginning with the constitutional mandate of assuming and promoting the protection of Spanish cultural heritage, and thereafter focusing on the concept of private ownership and its limits, in accordance with the social function of all property rights under the 1978 Spanish Constitution. Second, it describes a well-known case of illicit trade, focused on a valuable painting by Pablo Picasso. The work Cabeza de mujer joven (Head of a young woman) belonged to a private owner who decided to sell it internationally, using the services of a well-known auction house. When the required permission for exportation was denied by the Spanish public administration, the owner commenced a court proceeding aimed at changing the decision, but also planned to send the painting abroad using a yacht on his property. Thirdly, the article’s conclusion reflects on the level of severity of the Spanish legislation as applied in the case, in the context of the balance between cultural heritage protection and the freedom of disposition inherent to the right of property ownership.

Published: December 2023

Burdur ilinin güneyinde KD-GB uzanımlı Kestel Dağı’nın batısında kalan araştırma sahası, yaklaşık 176 km² alana sahiptir. Sahada yüzeylenen kayaların %64’ü karstlaşmaya uygun kayaçlardan oluşur. Kestel Dağı (Burdur) batısında yer alan kısmi karstik litolojiler üzerinde ve aynı zamanda flüvyokarstik süreçlerin birer eseri olan polyelerin oluşum ve gelişim özellikleri ile bu karstik depresyonların morfometrik analizleri araştırılarak açıklanmaya çalışılmıştır. Bu amaçla öncelikle 1/100.000 ölçekli M24 ve N24 jeoloji paftalarından sahanın jeoloji haritası ve jeolojik kesitleri çıkartılmıştır. 1/25.000 ölçekli M24 c4, d3 ve N24 a2, b1 paftaları Coğrafi Bilgi Sistemeleri programlarıyla sayısallaştırılarak bunlardan lokasyon ve jeomorfoloji haritaları üretilmiştir. Sahanın tam ve kısmi karstik özelliklerdeki birimleri üzerinde gelişmiş en yaygın şekiller polyeler, flüvyokarstik vadiler ve dolinlerdir. Bu karstik yapılardan en dikkat çekici olanı da polyelerdir. Sahada glişen polyeler; Bereket, Üçboğaz, Aksu, Yeşildağ, Sinop, Kapaklı, Aziziye ve Bozlar polyeleridir. Sığ karstın en belirleyici şekilleri olan bu polyeler; Pliyosenin sıyrılma yüzeylerinde, özellikle Pliyo-kuvaterner tektonizmasının ve litolojik özelliklerin kontrolünde gelişmiştir. Üst Kretase-Orta Miyosen sonu arasında bölgeye yerleşen bu naplı birimler üzerinde veya birimlerin kontak zonlarında gelişen polyeler, litolojik sınırlarda veya tektonik hatlarda oluştukları için yapısal ve kenar polye karakterindedirler. Bunlar aynı zamanda Pliyosen vadileri üzerinde oluşmuşlar ve Pleistosen ortalarında dış drenaja açılmışlardır. Bu oluşum ve gelişim özellikleriyle çok dönemli-çok kökenli olan bu polyeler, aynı zamanda flüvyokarstik kökenlidirler. Yapılan morfolojik analizlere göre bu polyeler farklı morfolojiler göstermektedir. Tektonik hatların uzanımı, blok faylanmalar, paleo vadilerin uzanımları, morfolojideki gençleşmelerin ortaya çıkardığı flüvyal etkiler nedeniyle polyeler eliptik, yarı eliptik veya uzamış özellikler sunmaktadır. Hesaplanan indis değerlerine göre ise bu polyeler dairesellikten az veya çok uzaklaşmışlardır.

Published: December 2023

Distrust of vaccines is one of the key problems of modern healthcare both in Russia and abroad. Mass vaccination against SARS-CoV-2 provoked a large number of social media narratives. Online communities play an important role in the formation and dissemination of narratives. The complex system of numerous online platforms for discussing the topic of vaccination on a social network deserves a special description.

The purpose of the study is to construct a typology of all significant communities of the popular Russian social network “VKontakte” that publish content on the topic of vaccination against COVID-19 (01/01/2020 – 03/01/2023) and describe it in terms of lobbied narratives. Big data collection and analysis methods were used, as well as narrative analysis. Of the 131,119 communities that published at least one vaccination message during the study period, 691 were selected based on self-positioning criteria (name, description) and/or the number of SARS‑CoV-2 vaccination messages above the established threshold. 14 thematic categories of communities have been identified, the self-positioning of which allows reconstructing narratives about forced vaccination and the right to choose; health care and debate about the benefits/effectiveness of vaccination; conspiracy theories; beneficiaries and trust in the authorities; pseudoscience, vaccination myths and scientific knowledge; childcare and parental rights; contrasting medical science with religious beliefs.

Narratives formed by online communities signify a pronounced polarization of opinions in the digital society regarding SARS-CoV-2 vaccination. The “pro-waxer” and “anti-vaxxer” narratives are reconstructed. Quantitatively “anti-vaxxer” communities significantly predominate over “pro-waxer” ones.

In order to achieve company objectives, marketing is the strategic process of discovering, promoting, and providing value to customers. It includes a variety of activities like as market research, product development, promotion, and sales, all with the goal of increasing consumer awareness, interest, and loyalty. In today's competitive industry, effective marketing is critical for businesses to engage with their target audience and generate growth. To do so, understanding the distinction between direct and indirect marketing - and tailoring it to their target audience- is vital for businesses to optimize the effectiveness of marketing efforts. Marketing is essential and in the digital age understanding the dynamic between the two advertising methods is of growing relevance, thus making this study of importance. The present study aims to investigate the effectiveness of direct and indirect advertising in persuading consumer behavior. It was conducted using a small sample group belonging to the upper socio-economic background from New Delhi, NCR and Gurgaon, Haryana. Using a questionnaire, their preferences on direct (Billboards, Youtube and Offers) and indirect (Social media, Celebrity endorsement and Product Placement) were analyzed. It was found that direct advertising was rewarded more informative, creative and influential in comparison.
DIGITAL THREADS: ANALYZING THE EFFECTS OF TECHNOLOGICAL INTERVENTIONS ON INDIA'S IKAT ARTISAN ECONOMIES
Authors: Dhar Shivv
Published: December 2023

Historically, the Indian handloom sector has experienced a curious trajectory, from a tradition dating back thousands of years to a craft that severely suffered under British rule. Despite the importance attributed to hand-spun swadeshi cloth during the Indian independence movement, many weavers are barely able to make ends meet today. This has been compounded further by the advent of the digital age and internet technologies. Recognizing this, several technological interventions have been deployed in India's ikat artisan economies during the 21st century. This spans from the Digital Empowerment Foundation (DEF), its flagship program Digital Cluster Development Programme (DCDP), alongside other notable organizations like Microsoft and Tata Trusts. Hence, this paper analyzes the effects of these interventions on India’s primary ikat hubs. Examining qualitative and quantitative data surrounding the impact of digital interventions on these communities, it will shed light on how digitalization can empower weavers within the handloom ecosystem, increase their wages, reduce the dominance of middlemen, and equip them with greater agency in the marketplace. This paper will also critically evaluate the approach taken by these interventions, its impact on the livelihood of weavers, and lastly, discuss the broader effects of digitalization within the context of a capitalist paradigm.

Google Classroom is practical for teachers and students as it makes the teaching and learning process more manageable. It is one of the practical pedagogical tools used by various higher educational institutions, as supported by previous studies. In line with this, the study is focused on exploring the factors that affect students’ acceptance of Google Classroom as an effective tool in learning Physical Education, adapting the Technology Acceptance Model (TAM). After obtaining data from 1,916 students currently taking minor PE in an online setting at City College of Angeles and after performing Partial Least Square-Structural Equation Modeling (PLS-SEM), the results revealed that students perceived ease of use positively predict their perceived usefulness of the LMS. Moreover, perceived ease of use positively influences students’ behavioral intention to use. Also, the students’ perceived usefulness increases behavioral intention to use Google Classroom in learning PE. Lastly, behavioral intent to use leverages students’ actual use of the educational platform. The findings of this study help the academic council and higher administration to decide if the said LMS can continuously be used as the college is still in a full-online learning modality. Recommendations and future research directions are also presented.

The purpose of this study was to develop a scale to assess the frequency of using classroom assessment tools and methods for mathematics teachers. This study was conducted on 320 Turkish mathematics teachers. The data were analysed using the SPSS 17.0 and LISREL 8.8 statistical software packages. EFA and CFA, item-total correlations, and convergent and discriminant validities were used to assess the construct validity. EFA and item analysis were performed with 170 mathematics teachers. After EFA, a four-factor scale with 25 items was identified, explaining 52.38% of the variance. The CFA was carried out with 150 mathematics teachers. The first and second-order CFA results indicated that the scale model had good fit indices, and the convergent and discriminant validity of the scale was confirmed. The Cronbach's alpha and composite reliability (CR) coefficients were satisfactory. The results of this study showed that the scale is a reliable and valid instrument for assessing the frequency of mathematics teachers’ use of classroom assessment tools and methods.

The use of artificial intelligence (AI) is becoming increasingly widespread in today's society. This type of technology, and more specifically chatbots as virtual assistants, can be implemented and integrated as a support tool in educational environments. This article proposes the creation of chatbots in the subject of didactic of geometry of the Degree of Primary Education of the Faculty of Education at the University of Málaga, carried out by 120 students in two groups. The aim is to analyse these chatbots, as well as the students' evaluation and satisfaction with them. To this end, the students were given brief training so that they could generate their own bots and know how to integrate them into a social network and then use them. The results of the questionnaire show that the students have shown interest in the generation of their chatbot and its integration into the social network, have improved their digital competence, as well as demonstrating a high degree of satisfaction with their AI creations, along with the idea that this type of experience can be transferred to other subjects and educational contexts.

The different accreditation processes of undergraduate degrees are the object of research due to the value of international recognition based on their accreditation. Thus, accreditation has become the preferred means of monitoring and evaluating the quality of higher education and observing universities' impact on society. The present study is part of a broader research focused on developing a doctoral thesis. It is framed in the qualitative interpretative paradigm of an emergent exploratory type. The main objective is to identify the public value generated by accreditation in the continuous improvement of undergraduate programs accredited by SINAES (an anagram of Sistema Nacional de Acreditación de la Educación Superior, National System of Higher Education Acceditation), in the field of education in Costa Rica. Five in-depth interviews were conducted to learn the perceptions of the key informants who participated in the accreditation process of the six selected degree programs. The results show the public value that accreditation produces in the continuous improvement of Education Degree Programs through ten categories that cover the achievements, benefits, results and effects of the contribution of SINAES in the continuous improvement processes of higher education. In conclusion, accreditation has become one of the determining factors when selecting an Education Degree Program in Costa Rica. The processes carried out by SINAES are perceived as legitimate and of excellence in developing these types of quality certifications.
lokura atada en el korasón del moso. Acerca de la actitud didáctico-moralista de los autores sefardíes de Robinson Crusoe.
Authors: Kacprzak Marta Katarzyna
Published: December 2023

La literatura sefardí moderna se basa principalmente en traducciones o adaptaciones de las novelas occidentales que se publicaban por entregas, tanto en series coleccionables como en folletines incluidos en algún periódico o, a veces, incluso como ediciones independientes. Entre estas obras encontramos las versiones sefardíes de una de las más célebres novelas de la literatura inglesa, esto es, de Robinson Crusoe, de Daniel Defoe. En la presente contribución se examinan las cuatro adaptaciones judeoespañolas publicadas entre finales del siglo XIX y principios del XX, haciendo hincapié en la judaización de la trama e indicando los fragmentos que reflejan la actitud didáctico-moralista de sus autores, Rafael Yitshak Benveniste y Ben Tsiyón Taragán.
Doctoral Students Balancing the Roles and Relationships of Counselor Education
Authors: Farrell Isabel , Barrio Minton Casey , DeDiego Amanda
Published: December 2023

Aspiring counselor educators in Council for Accreditation of Counseling & Related Educational Programs (CACREP)-accredited programs must learn to be counselors, teachers, supervisors, researchers, and leaders. These roles can overlap, creating multiple complex relationships during their programs. To examine these roles, we conducted a constructivist grounded theory investigation of how counselor education doctoral students (n = 9) balanced multiple roles and relationships and boundary crossings. We utilized chain referral sampling and continued until we reached theoretical saturation. We used semi-structured interviews conducted via videoconferencing (Zoom) for data collection and coded the interviews using two main phases: an initial phase and a focused coding phase. We used member checks by sending participants preliminary findings for feedback. The resulting theory describes two distinct stakeholders in the management of the multiple roles and relationships in counselor education: the students and the program. Students were responsible for balancing roles and responsibilities while considering professional growth, ethics, and boundary setting. The program was responsible for providing a growth-fostering environment and mentorship. Ultimately, the process of navigating multiple roles and relationships (MRRs) involves early discussion of MRRs, intentionality of program placement, assistance with boundaries and ethical decisions, and exposure to remediation and gatekeeping.

This study presents a numerical study of the effect of microridges on the performance of the three-lobe journal bearing considering lubricant compressibility and cavitation effects. A mathematical model based on the Reynolds equation that has been modified to take into account the effects of lubricant compressibility and cavitation has been proposed to achieve the primary goal of this work. Lubricant compressibility is considered by using lubricating oils with different bulk moduli while Elord's algorithm was used to consider the effect of cavitation. The governing equations for finite length journal bearing lubricated with Newtonian oil in laminar flow and isothermal condition are numerically discretised using the finite difference method and solved by using a suitable prepared computer program. The performance of the rough and smooth bearings was compared for plain and three-lobe journal bearings. The numerical model was demonstrated by comparing the pressure distribution for smooth and microridges three-lobe journal bearing with that published by El-Said et al. and they were found in good agreement. It was found that the pressure and the load were considerably enhanced and the coefficient of friction decreased by 15 % for three-lobe journal bearing with microridges in comparison with that of smooth surfaces.

Various mechanical parts come into high-load rolling and sliding contact at the contact surface. Even with technological advancements, mechanical failures still occur. Rolling-sliding mechanical contact issues are the primary cause of over 90 % of surface and subsurface metallic failures and they are only becoming worse. Using discretised continuum 2D finite element methods (FEM), this research investigates the parametric contact effect of a steel twin disc system subjected to rolling-sliding contact at varied surface friction and comprehensive load condition. The equivalent von Mises stress distribution, contact pressure distribution and shift position of maximum subsurface stress on the contour region are all influenced by changes in compressive load and coefficient of friction, according to a numerical surface-to-surface contact simulation performed with Abaqus at mean Hertzian pressure. The maximal equivalent stress, for a given load, reaches a peak in the subsurface and moves farther away from the surface when the coefficient of friction decreases and comes close to the contact surface when the coefficient of friction increases. Consistency is shown by the analytical and numerical results.

The absorber is a vital part of a solar air collector and has a significant impact on the overall efficiency of a solar air heating unit. The objective of this research is to examine and compare the performance of two distinct aluminium absorbers with and without aluminium fins by using experimental and numerical (computational fluid dynamics – CFD) methods. The studies were conducted in Mandalay, Myanmar, which is located at latitude 21.98° N and longitude 96.1° E, during December 2022. A plate absorber solar air collector (PASAC) and finned absorber solar air collector (FASAC) with the same absorber area of 0.889 m2 are compared in terms of their thermal performance. At a mass flow rate of 0.0389 kg/s, the average thermal efficiency, as computed numerically, is 53.5 % for FASAC, and the experimental results show a thermal efficiency of 54.2 %. Similarly, for PASAC, the numerical computation yields an average thermal efficiency of 44.4 %, while the experimental results indicate a thermal efficiency of 47.3 %. The FASAC outperforms PASAC in terms of thermal performance. The improved thermal performance of the double-pass solar air collectors with aluminium-finned absorbers can be advantageous for employment as a drying process unit.
