Authors: Zhou Hao-Han , Zhang Hui , Xiong Ze-Miao , Zhang Yun-Fei , Du Fei-Peng
Published: June 2024

Simultaneously improving electrical conductivity and Seebeck coefficient of carbon nanotubes to enhance their thermoelectric properties still poses substantial challenges. To enhance the thermoelectric properties of single-walled carbon nanotubes (SWCNTs), a physical blending method is employed to fabricate aniline tetramer nanowires/SWCNTs films (ANIT-NW/SWCNTs) by a simple blend of ANIT-NW and SWCNTs. The intertwining of ANIT-NW and SWCNTs creates a dense 3-dimensional network structure, establishing tight connections between SWCNTs bundles and ANIT-NW. The incorporation of ANIT-NW yields simultaneous enhancements in electrical conductivity and Seebeck coefficient, which is achieved by markedly increasing carrier mobility and reducing carrier concentration, respectively. The resulting power factor (
PF
) of ANIT-NW/SWCNTs reaches an impressive value of 146.7 μW·m
−1
·K
−2
. Furthermore, by utilizing ANIT-NW/SWCNTs as p-type legs and polyethyleneimine/SWCNTs as n-type legs, a thermoelectric module comprising 5 pairs of legs is constructed. This module exhibits an open-circuit voltage of 22 mV and an output power of 2.94 μW when subjected to a temperature difference of 50 K, while being loaded with a 60-Ω resistor. Therefore, these findings demonstrate the potential applications of ANIT-NW/SWCNTs films for flexible thermoelectric materials.

Authors: Ye Chenfei , Zhang Yixuan , Ran Chen , Ma Ting
Published: June 2024

Importance:
Pathological perturbations of the brain often spread via connectome to fundamentally alter functional consequences. By integrating multimodal neuroimaging data with mathematical neural mass modeling, brain network models (BNMs) enable to quantitatively characterize aberrant network dynamics underlying multiple neurological and psychiatric disorders. We delved into the advancements of BNM-based medical applications, discussed the prevalent challenges within this field, and provided possible solutions and future directions.
Highlights:
This paper reviewed the theoretical foundations and current medical applications of computational BNMs. Composed of neural mass models, the BNM framework allows to investigate large-scale brain dynamics behind brain diseases by linking the simulated functional signals to the empirical neurophysiological data, and has shown promise in exploring neuropathological mechanisms, elucidating therapeutic effects, and predicting disease outcome. Despite that several limitations existed, one promising trend of this research field is to precisely guide clinical neuromodulation treatment based on individual BNM simulation.
Conclusion:
BNM carries the potential to help understand the mechanism underlying how neuropathology affects brain network dynamics, further contributing to decision-making in clinical diagnosis and treatment. Several constraints must be addressed and surmounted to pave the way for its utilization in the clinic.
Potential of NASA’s Plankton, Aerosol, Cloud, and Ocean Ecosystem (PACE) Satellite Observations in the Oxygen Bands for Determining Aerosol Layer Height over Ocean
Authors: Xu Xiaoguang , Chen Xi , Wang Jun , Remer Lorraine A.
Published: June 2024

Aerosol layer height (ALH) is an important but uncertain parameter for evaluating the impact of aerosols on weather and climate and for accurate atmospheric correction. This study aims to assess the potential for measuring ALH by the Ocean Color Instrument (OCI) on NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem satellite. OCI measures Earth-reflected solar spectrum including reflectance in the oxygen (O
2
) A and B absorption bands that are invaluable for determining ALH. We assessed the sensitivity and information contained therein in retrieving ALH over the ocean surface by using the radiative transfer simulation of OCI observations in the O
2
bands. The capabilities were also demonstrated using hyperspectral data measured by the TROPOspheric Monitoring Instrument (TROPOMI), as spectrally convolved into the OCI bands. Our results indicate that (a) OCI observations in the O
2
A band are sensitive to ALH, whereas those around the O
2
B band have relatively reduced sensitivity; (b) the most pronounced sensitivity to ALH is found in the 762.5 nm (and 690 nm) around the oxygen A (and B) bands, which are selected for ALH retrievals in this study; and (c) the ALH retrieved from OCI proxy data is in good agreement with the aerosol profile probed by CALIOP lidar. Overall, the ALH retrievals for both smoke and dust events exhibit a root mean square error of 0.49 km and 0.31 km, respectively, for the smoke and dust cases, aligning with the uncertainties of ALH as measured from the concurrent TROPOMI and the Earth Polychromatic Imaging Camera instruments. Therefore, this study suggests from OCI observations that we can generate ALH products with a well-characterized uncertainty. The technique and results presented in this study are suitable to develop a simple but robust ALH algorithm for OCI observations when the data become available.
Unconscious and Conscious Gaze-Triggered Attentional Orienting: Distinguishing Innate and Acquired Components of Social Attention in Children and Adults with Autistic Traits and Autism Spectrum Disorders

Published: June 2024

Typically developing (TD) individuals can readily orient attention according to others’ eye-gaze direction, an ability known as social attention, which involves both innate and acquired components. To distinguish between these two components, we used a critical flicker fusion technique to render gaze cues invisible to participants, thereby largely reducing influences from consciously acquired strategies. Results revealed that both visible and invisible gaze cues could trigger attentional orienting in TD adults (aged 20 to 30 years) and children (aged 6 to 12 years). Intriguingly, only the ability to involuntarily respond to invisible gaze cues was negatively correlated with autistic traits among all TD participants. This ability was substantially impaired in adults with autism spectrum disorder (ASD) and in children with high autistic traits. No such association or reduction was observed with visible gaze cues. These findings provide compelling evidence for the functional demarcation of conscious and unconscious gaze-triggered attentional orienting that emerges early in life and develops into adulthood, shedding new light on the differentiation of the innate and acquired aspects of social attention. Moreover, they contribute to a comprehensive understanding of social endophenotypes of ASD.

Authors: Ahadi Mitra , Rouhbakhsh Zahmatkesh Mohammad Reza , Ebrahimi Parisa , AkbariRad Mina
Published: June 2024

Inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), is a chronic immune-mediated disease. The incidence of IBD is influenced by various genetic and environmental factors, with dietary habits gaining significant scientific interest. While the role of diet in the pathogenesis and development of IBD is still debated, recent studies have demonstrated its potential impact. However, conflicting findings exist regarding the efficacy of dietary interventions in the treatment and control of IBD. This review aimed to summarize the current understanding of the relationship between diet and IBD, highlighting the different perspectives and reasonings observed in recent studies. Overall, it has been shown that dietary habits play a role in the incidence of IBD, and adopting a controlled dietary approach may help manage the disease. Consequently, diet can be considered a predictive and prognostic factor in IBD.

Authors: Parsi Abazar , Hajiani Eskandar , Sadani Somayeh , Hashemi Seid Jalal , Seyedian Seid Saeed , Alimadadi Mehdi , Ghanbari Reza
Published: June 2024

Background: Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in the world. Previous studies revealed that cholecystectomy may be considered a risk factor for the development of NAFLD. The aim of this study was to compare the amount of liver fibrosis, determined by elastography, between patients with NAFLD with and without a history of cholecystectomy. Methods: In this descriptive-analytical cross-sectional study, 50 patients with NAFLD were divided into two groups: one with a history of cholecystectomy and the other without. No significant differences were found between these two groups in terms of age or sex distribution. Liver fibrosis was measured for all patients using an elastography imaging system. Subsequently, the data related to liver fibrosis, along with the demographic information of the patients, were statistically analyzed using SPSS software version 22. Results: The mean elastography score in all patients was 10.66±12.18 kPa (the elasticity scale ranging from 3.80 to 66.40 kPa). The group with a history of cholecystectomy had a significantly higher mean elastography score (13.39±16.20 kPa) compared with the group without cholecystectomy (7.93±4.99 kPa) (P=0.02). Additionally, there was a significant positive correlation between body mass index (BMI) and the mean elastography score in the group of patients with a history of cholecystectomy. Conclusion: The mean elastography score of patients with NAFLD with a history of cholecystectomy was approximately twice as high as that of non-cholecystectomy patients.

Published: June 2024

Background: Gluten sensitivity (GS) is one of the gluten-related disorders (GRDs). Patients with GS may have serum antibodies against tissue transglutaminase (tTG) (IgA and IgG) without any evidence of enteropathy. We aimed to evaluate both tTG-6 and tTG-2 antibodies to determine the prevalence of seropositive tTG-2 and tTG-6 antibodies in patients with multiple sclerosis (MS). Methods: In this cross-sectional study, we carried out serological tests (IgA & IgG anti-tTG-6 and tTG-2 antibodies) in patients with MS. Results: Seventy-two patients with MS were included in this study. Of them, seropositive patients for total (IgA+IgG) of tTG-6 and tTG-2 autoantibodies were 9.7% (95% CI, 4.2-18) and 5.6% (95% CI, 1.4-12.5), respectively. Conclusion: Anti-tTG-6 antibody testing may be necessary for early diagnosis of GS in patients with MS. More studies with larger sample sizes are warranted to confirm these data.

Published: June 2024

Background: In pediatrics, appendicitis is the leading cause of emergency surgery. It was previously believed that postponing the surgery could lead to the appendix rupture. Children with this condition can be difficult to diagnose. The evidence regarding the necessity of an immediate appendectomy is a topic of debate. In this study, we evaluated the medical records of patients who were diagnosed with acute appendicitis to determine whether postponing appendectomy for one night is safe or not. Methods: This study involved 534 individuals diagnosed with acute appendicitis, who were separated into two groups: those who underwent an appendectomy immediately (within 8 hours) and those who had a delayed procedure (between 8-18 hours). We recorded and compared demographic data, symptoms, laboratory results, time of symptoms, hospitalization duration, surgery duration, overall time, length of stay after surgery, and any other complications that occurred between the two groups. Results: The rate of surgical site infection (SSI) did not differ significantly between the groups (2.8% vs 4.2%, P=0.74). Additionally, there was no significant difference in the risk of perforation between the time of surgery in our study (21.9% vs 19.8%, P>0.05). Conclusion: Our findings suggest that there is no increased risk of complications such as perforation when appendectomy is delayed for up to 18 hours.
Simultaneous Occurrence of Wilson’s Disease, Autoimmune Hepatitis, and Hereditary Hemochromatosis: A Diagnostic Challenge
Authors: Fatemi Reza , Movassagh-koolankuh Shahryar , Mosadeghi Nazanin
Published: June 2024

This is not surprising to detect iron overload in chronic liver diseases and end-stage liver diseases since Kupffer cells scavenge necrotic hepatocytes during the course of liver damage, leading to an increased serum iron level and transferrin saturation compatible with iron overload even in the absence of a genetic mutation suggestive of hereditary hemochromatosis. Therewith, a relative association has been found between some sorts of chronic liver diseases like non-alcoholic steatohepatitis and hepatitis C with human homeostatic iron regulator protein (HFE: High Fe2+) gene mutations. Moreover, impairment of ceruloplasmin ferroxidase activity in the course of Wilson’s disease (WD), leading to the accumulation of ferrous ions just like what is expected in aceruloplasminemia, is another known reason for iron overload accompanied by chronic liver disease. Of chronic liver diseases, autoimmune hepatitis (AIH), and cholestatic liver diseases are less related to iron overload. Accordingly, the coexistence of WD, AIH, and hereditary hemochromatosis when there exist clinical features, laboratory tests, genetic confirmation, and histological evaluations indicative of the three mentioned diseases is exceedingly rare. Here, we present a 55-year-old man referred with progressive generalized icterus accompanied by loss of appetite and significant weight loss. The presented case was not an appropriate candidate for liver biopsy due to recent coronary angioplasty and the urgent need for dual antiplatelet therapy. However, medical follow-ups were highly suggestive of concomitant WD, hereditary hemochromatosis, and AIH. The attempts failed for the treatment of hereditary hemochromatosis and WD with chelating agents until the completion of the course of treatment with immunosuppressants targeting components of the AIH-related immune system.
Consumers’ Perception of Social Media Influencers: A Study of Skincare Brands in Nigeria
Authors: Kayode-Adedeji Tolulope , Okechukwu Ifunanya , Oyedepo Tunji
Published: June 2024

In the highly competitive consumer market, brand owners are working tirelessly towards retaining their ‘loyal’ customers, and ensuring that the consumers of other brands make a switch to their products; all these are geared towards remaining relevant in the business world. Hence, social media has become a viable medium to pass these messages as a result of the increasing impact of modern technology and “know-how.” The engagement of well-known personalities for social media brand influencing has become a viable tool employed by brand owners to give maximum visibility to their products. They are influential because online users, in most cases, adopt their personalities as role models while many others idolize them. Hence, their promotion of brands and products on social media is usually widely accepted by these groups of consumers. In recent times, there have been reports and cases of influenced skincare brands and products that have fallen short of efficacy and quality as purported by the influencers of the brands in question. Consumers have expressed dissatisfaction, frustration, and waste of money regarding the purchase and usage of some skincare brands that were purchased as a result of the content created around the products by their social media influencers. Therefore, this study seeks to examine consumers’ perception of the engagement of social media influencers of skin-care products using Focus Group Discussion and a survey of female respondents who are known to use skincare products. Results show that the use of influencers does not necessarily inform their purchase or usage of certain skin care products. This is because, first, skin care products are sensitive and could damage customers’ skin, which makes them purchase through referrals rather than depending on influencers’ reports about the product. Second, the social media platform is commonly known as a medium that online users can easily manipulate for deception. The study suggests that Influencers should adopt credible means of creating awareness for their brand.

Hiệu ứng tăng cường tín hiệu Raman bề mặt đã thể hiện sự ưu việt của mình trong việc phát hiện và phân tích các hợp chất có hoạt tính dược (PhAC). Sự tiện lợi và ứng dụng thực tế của SERS phụ thuộc nhiều vào việc chế tạo đế kim loại. Điều này còn phức tạp hơn khi được triển khai bên trong lòng các kênh dẫn vi lưu. Trong nghiên cứu này của nhóm, kỹ thuật khử bằng laser đã được sử dụng để tạo ra các hạt Bạc nano trên đế kính trong kênh. Các thông số như thời gian chiếu và công suất laser đã được khảo sát để thu được đế SERS tốt nhất. Các đế này sau đó sẽ được sử dụng để phân tích hoạt chất Rhodamine B. Các kết quả cho thấy, với thời gian chiếu là 30 giây tại công suất 0,11 mW thì đế SERS thu được cấu hình tốt nhất với các hạt nano có kích thước nằm trong dải từ 20-40 nm và có độ phân bố đồng đều. Đáng chú ý, tín hiệu Raman thu được có mức tăng cường lớn hơn 7 lần khi không có đế, qua đó xác nhận được hiệu quả của nghiên cứu.

УРАЖЕНІСТЬ КАРІЄСОМ ПОСТІЙНИХ ЗУБІВ У ДІТЕЙ ІЗ ЗУБОЩЕЛЕПНИМИ АНОМАЛІЯМИ
Authors: Лесіцький М.Ю. , Кисіль А.Р.
Published: June 2024

На сьогоднішній день відмічається значна поширеність карієсу постійних зубів серед дітей України, що залишається актуальною проблемою як для практикуючих стоматологів, так і для науковців-дослідників. Крім того, привертає увагу також високий рівень поширеності зубощелепних аномалій серед дитячого населення. Багато досліджень свідчать про зв’язок між зубощелепними аномаліями та карієсом зубів, але існують також протилежні твердження, які не підтверджують даного зв’язку. Ці контроверсійні дані підкреслюють потребу у подальших дослідженнях у цьому напрямку. Мета дослідження. Вивчення поширеності та інтенсивності карієсу постійних зубів у дітей із зубощелепними аномаліями. Матеріал та методи дослідження. Для оцінки стану твердих тканин зубів обстежено 1167 дітей віком 6-16 років середніх навчальних закладів м. Львова. Серед них 743 дитини із ЗЩА (63,67 %) та 424 дитини без ЗЩА (36,33 %). Оцінку ураженості карієсом постійних зубів проводили згідно наступних показників: поширеності (у %) та інтенсивність карієсу (за показником КПВ). Характер прикусу (аномалії положення окремих зубів, аномалії зубних рядів, аномалії прикусу) оцінювали за класифікаціями Енгля Е. (1889) та Калвеліса Д.А. (1957). Наукова новизна. У даному дослідженні було вивчено ураженість карієсом постійних зубів у дітей із зубощелепними аномаліями. У результаті проведених досліджень встановлено, що у дітей із ортодонтичною патологією поширеність карієсу постійних зубів, в середньому, становить, 79,27±1,49 % при інтенсивності 3,78±0,23 зуба, тоді як у дітей з ортогнатичним прикусом – 58,02±2,40 % та 2,90±0,25 зуба, відповідно. Найбільший приріст інтенсивності карієсу констатовано у дітей із ЗЩА у вікові періоди з 6 до 7 років (у 2,3 рази) та з 11 до 12 років (на 57,40 %). Виявлено, що кількість запломбованих зубів переважає над каріозними на 63,83 % у дітей із ЗЩА, у дітей без ЗЩА на 90,91 %. Високий рівень інтенсивності карієсу постійних зубів корелює з відкритим, перехресним та дистальним прикусами – в усіх зазначених випадках виявлено прямий сильний достовірний зв’язок. Висновки. Отримані дані свідчать, що існує взаємозв’язок поміж наявністю зубощелепних аномалій та карієсу постійних зубів у дітей, а також про необхідність мотивації батьків до збереження стоматологічного здоров’я дітей. Високий рівень карієсу постійних зубів, який виявлено в асоціації з відкритим прикусом, перехресним прикусом та дистальним прикусом, що підтверджується прямим сильним достовірним зв’язком, може свідчити про більшу схильність до карієсу дітей із даними зубощелепними аномаліями та слугувати основою для подальших досліджень.

Мета. Оцінити розподіл спеціалістів та типів закладів, вплив досвіду, труднощі у знятті відбитку та дослідити сприйняття стоматологами впливу технологічного прогресу на зняття зліпків для повного знімного пластинкового протезування. Матеріал і методи. У дослідженні використовувався перехресний метод, в якому була відібрана вибірка зі 120 респондентів, що складалася з лікарів-стоматологів, зубних техніків, зубних гігієністів, за допомогою простої процедури випадкового відбору. Для збору інформації використовувався попередньо протестований структурований опитувальник. Описова статистика була представлена у вигляді частоти та відсотків. Для представлення даних використовувалися таблиці та рисунки. Для вивідної статистики використовувався критерій хі-квадрат. Результати. У поточному дослідженні комплексного знімного протезування розглядалися різні аспекти, пов’язані з фахівцями, технікою, проблемами, наслідками, заходами та технологічними досягненнями. Стоматологи склали найбільшу групу (37,5%) з різним стажем роботи, переважно від 1 до 5 років (34,2%). Більшість респондентів (60,8%) вважають якість зліпків надзвичайно або дуже важливою, наголошуючи на таких методах, як точні вимірювання та індивідуальні ложки, а також на таких проблемах, як труднощі з формуванням країв (28,3%). Серед поширених наслідків – погане прилягання протеза (24,2%) та дискомфорт пацієнта (20%), а рекомендовані заходи включають належне навчання (30,8%) та використання високоякісних матеріалів (23,3%). Хоча технологічний прогрес позитивно сприйняли 59,2%, скептично до нього поставилися 28,3% респондентів. Було виявлено значний зв’язок (p-value = 0,019) між досвідом та сприйняттям важливості якості зліпків, особливо серед лікарів з досвідом роботи від 1 до 5 років та понад 10 років, що підкреслює ключову роль якісних зліпків у забезпеченні успішного результату комплексного знімного протезування. Наукова новизна. Революційний підхід до успіху комплексного знімного протезування та надання пріоритету якісним зліпкам для ефективності. Висновок. Дослідження підкреслює вирішальну роль точних зліпків у комплексному знімному протезуванні. Різні рівні кваліфікації потребують майстерних технік. Такі виклики, як формування країв, вимагають проактивних заходів і технологічного прогресу для досягнення оптимального результату.
İlhanlı Devleti'nin Son Veziri: Hoca Gıyâseddîn Muhammed Reşîdî ve Dönemi
Authors: Özen Firdevs
Published: June 2024

Gıyâseddîn Muhammed, İlhanlı Devleti’nin en önemli vezirlerinden Reşîdüddîn Fazlullâh’ın en büyük oğlu idi. Vezirlik makamına gelmeden önce Ölceytü Han’ın ve Horâsân’da görev yapan Şehzade Ebû Saˊîd’in hizmetinde çalıştı. Ebû Sa´îd, 1317 yılında İlhanlı tahtına çıktıktan sonra devletin çeşitli kademelerinde çalışmayı sürdürdü. İlhan, Reşîdüddîn’in idamı sonrasında devletin işleyişinde karşılaştığı sorunlara çözüm üretemeyince bilgi ve tecrübesine güvendiği Gıyâseddîn Muhammed’i vezirlik makamına getirdi (727/1327). Gıyâseddîn, özellikle iktisadî ve malî alanlarda Gazan Han’ın reformlarını ve babasının yaptıklarını örnek alarak birçok düzenleme yaptı ve devletin öncelikli meselelerini çözüme kavuşturdu. Fakat devlette güçlü bir konuma ulaşması, onu Moğol emîrlerinin hedefi haline getirdi. Onu ortadan kaldırma amaçlı iki isyan yaşandıysa da başarısızlıkla sonuçlandı. Bundan sonra Gıyâseddîn, devletin kaderini belirleyen çok önemli bir olayda kritik bir rol oynadı. Ebû Sa´îd, 1335 yılında aniden vefat edince kontrolü eline aldı. Yaşanabilecek bir taht kavgasına meydan vermeyerek tahta Arpa Han’ı çıkarttı ve saray erkanı ile emîrlere onun ilhanlığını kabul ettirdi. Arpa Han tahta oturur oturmaz ilk iş olarak vezirlik görevine Gıyâseddîn’i tayin etti. Ancak Arpa’nın meşruiyeti konusunda devletin ileri gelenleri arasında bir uzlaşı yoktu. Çünkü Hülegü’nün soyundan değil, Hülegü’nün kardeşi Arık Buka’nın soyundan geliyordu. Gittikçe artan muhalefetin liderliğini Uyrat Emîr ´Alî Pâdişâh üstlendi ve tahta Mûsâ Han’ı çıkarttı. Arpa Han ile Mûsâ Han arasında 736/1336 yılında yapılan savaş, Arpa Han’ın yenilgisiyle sonuçlandı. Savaşta taktiksel hatalar yapan fakat iyi bir mücadele örneği sergileyen Vezir Gıyâseddîn Muhammed, yakalandıktan sonra ´Alî Pâdişâh tarafından idam edildi. Çalışmamızda Gıyâseddîn Muhammed’in yaklaşık dokuz yıllık vezirliğinde siyasî, iktisadî ve malî alanlardaki performansı ayrıntılı şekilde ele alınmış, ayrıca devrin âlimleri ve tasavvuf büyükleriyle ilişkilerine değinilmiştir.

Mit Forschendem Lernen im Praxissemester gehen laut Wolfgang Fichten (2017a) hohe Erwartungen in Bezug auf die Professionalisierung von (angehenden) Lehrkräften einher. Theoretisch wird die Zielsetzung des Praxissemesters häufig an die forschende Grundhaltung (Fichten 2017b) bzw. den „forschenden Habitus“ (Helsper & Kolbe 2002) angebunden. Dabei muss jedoch beachtet werden, dass mit der Referenz auf den „Habitus“ (Bourdieu 1987) stets eine Komponente der Enkulturation sowie ein Fokus auf praktisches Wissen einhergeht. In dieser theoretischen Rahmung zeigt sich die Herausforderung, einen forschenden Habitus zu generieren, der (auch) in einer der konkreten Produktion externen Praxis, wie bspw. dem Referendariat, ‚funktioniert‘. 12 Interviews mit Referendar:innen verdeutlichen, dass die kollektive Eingebundenheit und damit die Teilhabe an der ‚neuen‘ Praxis als notwendig erachtet wird und positiv gerahmt ist, aber Forschendes Lernen im Sinne einer forschenden Grundhaltung für die Referendar:innen keine praktische Funktion zu haben scheint.

Professionalisierung dokumentarisch rekonstruieren. Perspektiven einer funktionalen Analyse am Beispiel von Reflexionspraktiken
Authors: Katenbrink Nora , Schiller Daniel
Published: June 2024

Der Beitrag widmet sich der dokumentarischen Rekonstruktion von Praktiken der Reflexion. In einer praxeologisch-wissenssoziologischen Perspektive wird zunächst der Gegenstand Reflexion verstanden als nachträgliche Begründungs- und Legitimationspraxis Professioneller eingeführt. Im Anschluss wird mit der funktionalen Analyse eine Spielart dokumentarischer Interpretation in den Fokus genommen, die sich von Fragen leiten lässt, für welches Problem eigentlich welche Praxis eine Lösung ist. Am Beispiel zweier Fälle von äquivalenter Reflexion eigener Vermittlungspraxis (Schule & Hochschule) wird dann ein Typ von Reflexion als bekenntnishafte Absicherung der Praxis gegenüber Theorie und Norm beschrieben, sowie schließlich die methodologische Perspektive funktionaler Analysen für Professionalisierungsforschung zusammengefasst.

"Sei alles - werde Lehrer". Aushandlung und Aneignung berufsbezogener Subjektnormen durch angehende Lehrpersonen
Authors: Förster Magdalena , Parade Ralf
Published: June 2024

Öffentliche Diskurse über den Lehrberuf stehen aktuell wieder im Fokus wissenschaftlicher Auseinandersetzungen. Dabei ist wenig geklärt, welche Relevanz sie für Professionalisierungsprozesse besitzen. Für den Beitrag wurden Analysen öffentlicher Lehrer:innenbilder mit der Rekonstruktion einer Gruppendiskussion verschränkt, um so Subjektivierungsprozesse angehender Lehrpersonen nachzuzeichnen. Die Rekonstruktionen zeigen, wie antagonistische Subjektnormen einer entgrenzten Zuständigkeit – im Sinne von potenziell überfordernder Allzuständigkeit und idealisierender Omnipotenz – im Lehrberuf miteinander verwoben sind und wie sie von Lehramtsstudierenden ausgehandelt und angeeignet werden. Abschließend diskutieren wir vor diesem Hintergrund eine diskurstheoretische Perspektive auf Professionalisierung im Lehrberuf. (DIPF/Orig.)
Revision of the distribution of Ranunculus illyricus in Slovakia after four decades
Authors: Pariľáková Michaela , Miháliková Tatiana , Dudáš Matej
Published: June 2024

Ranunculus illyricus is a typical xerothermic plant. The main part of its northern distribution area lies in the territory of Slovakia. Based on an intensive field study and the revision of herbarium specimens in central European herbaria, we prepared an updated distribution map of Ranunculus illyricus in Slovakia. The species was recorded in Slovakia in 16 phytogeographical districts situated in the area of the Pannonian and nine in the area of the Carpathian flora, respectively. The species is continuously widespread in southern parts of the country; towards the east, the number of populations significantly decreases, but the populations are often numerous. Based on the distributional data, the inclusion of Ranunculus illyricus into the near threatened (NT) category in the current Red List of Flowering Plants in Slovakia is correct.

Authors: Onieva Mallero María Rosario , Parra Valcarce David
Published: June 2024

Introducción: Se analiza de qué manera los cibermesdios españoles especializados en salud emplean el formato pódcast, entendido como la combinación de los términos iPod y broadcasting, dentro de su estructura productiva como fórmula para acceder a segmentos de población poco proclives a recibir sus contenidos. Metodología: Se han seleccionado seis cibermedios especializados considerados de referencia dentro del sector español de la salud (Diario Médico, Redacción Médica, Gaceta Médica, Con Salud, Diario Sanitario y Espacio Sanitario) y se han examinado los diversos pódcast que cada uno de estos medios genera y soporta en sus respectivas páginas web. Resultados: Con Salud, con tres pódcast, y Redacción Médica, con siete pódcast, son los dos cibermedios que apuestan por esta tecnología. En el caso de los cuatro restantes, no se ha detectado el empleo de este formato de modo sistemático. Discusión: Los ejemplos de pódcast analizados dejan entrever la posibilidad de soportar toda clase de géneros periodísticos: entrevistas en profundidad, reportajes, noticias y comentarios editorializantes. Asimismo, incorporan diversas plataformas de podcasting para apoyar su distribución, incluyendo Google Podcasts, iVoox, SoundCloud y Spotify. Conclusiones: Una parte apreciable de los cibermedios españoles especializados en el sector de la sanidad prestan un creciente interés hacia los pódcast, un hecho que desde el punto de vista cronológico surge entre finales de 2021 y comienzos de 2022 y que cabe enmarcar en la etapa de eclosión en la que actualmente se ve envuelta este formato en toda clase de sectores productivos.

The Causes of Re-exam and Its Role of in Improving Academic Achievement of Low Scoring Students in Haramaya University
Authors: Hussen Anwar Ahmed
Published: June 2024

Re-exam is a form of supplementary assessment designed to provide second opportunity for students who scored final course marks between [30 and 40).  This study employed survey design that involves both quantitative and qualitative approaches. Questionnaire, interview and document analysis for collecting data from both primary and secondary sources were designed and executed. 315 students and 15 instructors were incorporated as a sample using stratified random and purposive sampling techniques respectively. Available sampling technique was utilized to add 10 cluster registrar heads and 18 registrar data managers as a sample. The finding of the study showed that: poor academic background of the students, health problem at the time of exam and deliberately scoring FX grade were the main causes that expose students to score FX grade. Additionally, it was found out that, majority of students scored FX grade in across departmental courses than home base courses. The finding further indicated that, re-exam is playing great role in helping low achieving students to improve their academic achievement as 43% of the students who scored FX grade in their first assessment have scored C and above marks after re-exam. The relationship between study year level and the number of students who scored FX grade (r = -0.92, p < 0.05) is negative and significant. The computed t-test result t(971) = 1.0, p> 0.05 indicated that males and females are not differed significantly on their achievement of re-exam.
MORAL UPBRINGING IN THE PROCESSES OF RELIGIOUS EDUCATION
Authors: Marek Zbigniew , Mółka Janusz , Szymańska Maria
Published: June 2024

The article is aimed at showing the meaning of moral education in the processes of religious education. The authors pay attention to the meaning of moral values influencing man’s behaviour, attitudes to Self, other people, world, and God.  Experience obtained in the relationship with Self, others and God has a significant role in the trajectory of educational processes, particularly the process of moral upbringing of a person. Attention paid to natural cognition and cognition rooted in God can help underlining the sense of religious education, also religious education of a child. Moral imagination producing moral images becomes the subject for analysis in terms of teacher’s responsibility concerning the selection of literature items, or ways of their analysis. Moral upbringing tightly connected with religious education elicits the meaning of work upon own character and catechesis as a tool enhancing its quality. The research question of this article can be posed: How does moral upbringing participate in the processes of religious education?
EVALOE-DSS as a self-assessment and decision-making tool on the teaching of oral language in a school context: results of a pilot study
Authors: Gràcia Marta , Amado Laura , Jarque Sonia , Bitencourt Daniela , Vega Fàtima , Riba Carles
Published: June 2024

School is a natural context for development in which the communicative strategies used by teachers when interacting with students are essential for the development of communicative and linguistic competence. The objective of this study was to construct, implement and validate a first version of a self-assessment and decision-making tool on the teaching of oral language at school. It is an adaptation of the Oral Language Assessment in the School Context Scale (Escala de Valoración de la enseñanza de la Lengua Oral en contexto Escolar-EVALOE) (Gràcia et al., 2015) based on the use of the Conversational Methodology. This is a multiple case study focusing on four teachers (1 from an ordinary school, 2 from a rural school and 1 from a special education school). For six months, the teachers self-assessed their teaching practices with the tool, made decisions to improve it, and introduced changes in their classes. The researchers observed five class sessions of each teacher, assessed them with the same tool and each teacher-researcher pair conversed and reflected on the classes in five meetings throughout the semester. The results show that, in spite of the fact that there were important differences between teachers, the EVALOE - Decision Support System (EVALOE-SSD) is a useful tool that facilitates self-assessment, decision-making and the introduction of changes in the classes in order to promote the development of communicative and linguistic competence in the students. The analysis identified elements that can be improved and that will be considered during the review of the tool.

رابطة شباب جنوب إفريقيا التشكيل التنظيمي والبناء الفكري والعقائدي 1918-1948
Authors: أ.م.د. احمد محمد جاسم عبد
Published: June 2024

عدت هذه الرابطة إنموذجاً فريداً في الحركات المسيحية السياسية المتطرفة في إفريقيا ، فهي رابطة سرية تعمل على تسيد قومية الأفريكانرز في جنوب إفريقيا ، عن طريق المحافظة على تاريخهم وثقافتهم ولغتهم ، فهي تمثل أقصى اليمين المتطرف، إذ عملت على تسيس الدين لتحقيق غايات سياسية ، لذا حاولت الرابطة بوصفها جماعة دينية سياسية متطرفة فرضت أفكارها وعقيدتها على المحيطين بها من منطلق نخبوي ، فأعطت لنفسها الحق في التفكير واتخاذ القرار نيابة عن الأخرين لصالح نخب معينة ، مروجة لمصالحها الخاصة باستخدام النص الديني والعقيدة الفكرية تحت زعم أن لهم من المعرفة والأيمان ما يخولهم اختيار مصائر البشر وفرض تفسيراتهم للنص الديني على الأخرين لاسيما البسطاء منهم.   وتوصلت الدراسة إلى عدد من الأستنتاجات منها: إن الرابطة هي الوجه الحقيقي للإرهاب الديني المسيحي في جنوب إفريقيا، كما أنها تمثل المعنى الحقيقي لمفهوم الدولة العميقة ، لاسيما باستخدامها العاطفة الدينية لاحتواء العقول ، من أجل تحقيق غاياتها بالسيطرة على الاقتصاد والسياسة .
