This research was carried out in order to investigate the perceptions of Civil Aviation Training Center (CATC) students about the use of the Test of English for International Communication (TOEIC) results before studying at CATC and before co-operative education enrollment. The objective of this research was to study the perception of using TOEIC results before studying and before cooperative education enrollment and the factors that affected the perception of learning English for the Test of English for International Communication (TOEIC) and study the development of their English language skills for TOEIC preparation in order to propose guidelines for the development of English learning to the TOEIC test by studying and collecting data from 378 participants of 1st and 3rd year undergraduate students of CATC, Bachelor of Technology in Aviation Program in Aviation Management and Bachelor of Engineering in the academic year 2019 by using questionnaires and a random interview of 68 students. The results showed that most respondents get 405-600 English TOEIC score or Elementary Proficiency Plus level. Students were aware that CATC has clearly publicized that TOEIC result would be used for consideration before enrolling and before joining cooperative education. They realized that TOEIC was the one of a reliable and useful English language proficiency assessment. Regarding self-test preparation, it was found that most of the students were good self-learners by being aware that it must be well prepared before the test. They set their own goals in the test and also prepared their own materials used in test preparation. In the analysis of one's own ability, students knew their weaknesses and were able to improve themselves. Students realized that they would receive a higher score after their good preparation. And we also found that the helps and advices from lecturers would make students felt more confident during the TOEIC preparation process.

A regressão linear tem sido amplamente utilizada em diversas áreas de conhecimento devido sua praticidade. Na ciência florestal, essa ferramenta é fundamental para modelagem de variáveis e relações dendrométricas. No entanto, para a adequada aplicação, algumas premissas devem ser atendidas, dentre as quais destacam-se a normalidade dos resíduos e a homogeneidade das variâncias, as quais são frequentemente violadas. Nessa perspectiva, as estratégias de transformação de variáveis são alternativas promissoras para corretas inferências estatísticas. Diante disso, objetivou-se avaliar diferentes estratégias de transformação em modelos de regressão linear para predição da altura e do volume por árvore em povoamentos e florestas naturais. Para a modelagem da relação altura-diâmetro, foram empregados dados de Pinus oocarpa em idades de 5 e 19 anos. Para a modelagem do volume, foram utilizadas bases de dados de florestas naturais da Amazônia e da Mata Atlântica, além dos povoamentos de P. oocarpa. Foram testadas distintas estratégias de transformação de variáveis: Log, recíproca, Box-Cox, Manly, Bickel-Doksum, Yeo-Johnson, Glog, Dual power, G power, Log shift, raiz quadrada deslocada e raiz quadrada. As modelagens com variáveis transformadas que corrigiram simultaneamente as premissas de normalidade dos resíduos e homocedasticidade foram avaliadas estatisticamente para a seleção das estratégias mais adequadas. Assim, orienta-se a transformação em situações na qual pelo menos um dos pressupostos é violado. Nessas ocasiões, em estudos da relação altura-diâmetro, recomenda-se as estratégias de Manly e Box-Cox, ao passo que, em modelagens volumétricas, indicam-se a aplicação do logaritmo e de Box-Cox.
FromDunamisas Active/Passive Capacity toDunamisas Nature in Aristotle’sMetaphysicsTheta
Authors: Gonzalez Francisco J.
Published: August 2023

Aristotle notoriously begins his examination of being in the sense ofdunamisandenergeiainMetaphysicsTheta with what he describes as the sense that is ‘most dominant’ but not useful for his present aim. He proceeds to define the not-useful sense ofdunamisas “the principle of change in something else or in itself qua other”, along with other senses derived from this primary sense. But what then is the useful sense? All that Aristotle tells us at the outset is that it is a sense that extends “beyond things spoken of only in relation to motion” and nowhere in Book Theta does he explicitly identify the useful sense as such. This has allowed for very different interpretations of the useful sense in the literature, the primary ones being that it is (1) ‘possibility’, (2) the potential to receive a form, (3) being-potentially-x understood modally as encompassing all specific senses ofdunamis, and (4) capacity for substantial change. The present paper argues that there are significant problems with all of these suggestions and defends an identification of the useful sense ofdunamiswith the sense that Aristotle explicitly opposes to the not-useful sense at the start of Theta 8:phusis(‘nature’). This goes hand-in-hand with an identification of the useful sense ofenergeiawith ‘activity’ as distinguished from motion/change at the end of Theta 6. What makes these senses ofdunamisandenergeiathe useful ones for Aristotle’s present aim is that they are required to explain fully the priority ofenergeiatodunamisin substance defended in Theta 8, they support the identification in Theta 9 ofenergeiawith the good, and they explain the unity of the only substances that Aristotle recognizes as being genuinely substances: natural living substances.
Impact of WO3 and BaO nanoparticles on the radiation shielding characteristics of polydimethylsiloxane composites
Authors: Alorain Dalal A. , Almuqrin Aljawhara H. , Sayyed M. I. , Elsafi Mohamed
Published: August 2023

In this study, we developed flexible composites using silicone rubber (SR) or polydimethylsiloxane as the matrix and WO3 and BaO nanoparticles as filler to analyze their radiation-shielding performance. The linear attenuation coefficient (LAC) values for the prepared composites were reported to range from 0.059 to 1.333 MeV by using the experimental method. At 0.059 MeV, the SR with 40% of BaO NPs possesses the highest LAC, followed by SR with 20% of BaO and WO3 NPs. The SRs S-2 and S-4 that contain WO3 and/or BaO exhibit continuously greater LAC values than the sample S-1. Numerically, the LAC for S-2 (with 40% of BaO NPs) is 1.6 times greater than that for S-1 (free BaO and WO3) at 0.662 MeV, while the LAC for S-2 is 1.47 times more than that for S-1 at 1.275 MeV. We examined the impact of the thickness of the prepared composites on the attenuation performance by studying the transmission factor (TF) at two different thicknesses (1 and 2 cm). For S-1 and S-2, the TF decreases due to the increase of the thickness from 1 to 2 cm. The TF for S-1 with a thickness of 1 cm is 75% at 0.059 MeV, while it is 56% (for 2 cm). We evaluated the percentage decrease in the TF at 0.059 MeV for every SR as the thickness changes from 1 to 2 cm. For S-3, S-4, S-5, and S-6, the percentage decrease in the TF is extremely significant varying from 98% to 99%. This suggests that increasing the thickness of these SR samples from 1 to 2 cm has a major effect on the shielding capabilities they possess, particularly at low energies.

Published: August 2023

Training, sports equipment, and facilities are the main aspects of sports advancement. Countries are investing heavily in the training of athletes, especially in table tennis. Athletes require basic equipment for exercises, but most athletes cannot afford the high cost; hence, the necessity for developing a low-cost automated system has increased. To enhance the quality of the athletes’ training, the proposed research focuses on using the enormous developments in artificial intelligence by developing an automated training system that can maintain the training duration and intensity whenever necessary. In this research, an intelligent controller has been designed to simulate training patterns of table tennis. The intelligent controller will control the system that sends the table tennis balls’ intensity, speed, and duration. The system will detect the hand sign that has been previously assigned to different speeds using an image detection method and will work accordingly by accelerating the speed using pulse width modulation techniques. Simply showing the athletes’ hand sign to the system will trigger the artificial intelligent camera to identify it, sending the tennis ball at the assigned speed. The artificial intelligence of the proposed device showed promising results in detecting hand signs with minimum errors in training sessions and intensity. The image detection accuracy collected from the intelligent controller during training was 90.05%. Furthermore, the proposed system has a minimal material cost and can be easily installed and used.

Published: August 2023

The unique optical properties of squaraine dyes make them promising for cancer phototheranostics, but the reported squaraines for in vivo treatments mainly rely on their photothermal effect, where monotherapy cannot achieve the desired therapeutic effect. Here we generated a type of squaraine capable of killing tumors through both photothermal and photodynamic effects. We optimized squaraine structure with selenium modulation and formulated it into nanoparticles that showed strong absorption of infrared light, negligible fluorescence, good photothermal conversion (66.6 %), and strong photodynamic effects even after several irradiation cycles. In addition, the nanoparticles could be tracked through their strong optoacoustic signal. In mice, the nanoparticles effectively accumulated in tumors and eliminated them upon irradiation, without causing adverse effects. Our work demonstrates the potential of selenium modulation of squaraine for precise cancer diagnosis and treatment through synergistic photothermal and photodynamic effects.
Proper Orthogonal Decomposition analysis of mode switching in supersonic jets impinging on flat and corrugated plates
Authors: Sarangi Debivarati , Karthik Ramanujam , Srinivasan Kothandaraman
Published: August 2023

Understanding the occurrence of various feedback mechanisms of an under-expanded impinging supersonic jet is a crucial task in research. The presence of several jet modes is examined in this study for the flat and corrugated impinging plate geometries. The behavior of impinging plate configurations during mode switching is investigated by varying the flow state, such as the jet Mach number. The staging behavior at various jet Mach numbers is observed using acoustic spectral plots and schlieren flow visualization. To explore the presence of various types of modes during the jet impingement due to the modification of jet Mach number, ensemble averaging and Proper Orthogonal Decomposition of schlieren images are carried out. In the majority of situations, the corrugated design shows a reduction in tonal noise and overall sound pressure level. In exceptional cases, for the corrugated plates, the enhanced overall sound pressure level is caused by the existence of axisymmetric instability (A1, A2).
Force mismatch in clausal ellipsis
Authors: Landau Idan
Published: August 2023

Recent studies reveal that the values of finiteness, tense, modality and polarity in a clause elided under sluicing may be distinct from their correlates in the antecedent clause. Focusing onCP ellipsisin Hebrew (an instance of Argument Ellipsis), we first demonstrate that it is distinct from both Null Complement Anaphora and (null) pronominalization, and then show that the values offorce(declarative, imperative, interrogative) can be distinct between the antecedent and the missing clause as well. Possible mismatches are bidirectional, ruling out “subset” theories of identity in ellipsis and challenging certain accounts of the semantics of polar questions. Implications for the general theory of ellipsis are discussed and evaluated.

MacDougall, KB, McClean, ZJ, MacIntosh, BR, Fletcher, JR, and Aboodarda, SJ. Ischemic preconditioning, but not priming exercise, improves exercise performance in trained rock climbers. J Strength Cond Res 37(11): 2149–2157, 2023—To assess the effects of ischemic preconditioning (IPC) and priming exercise on exercise tolerance and performance fatigability in a rock climbing–specific task, 12 rock climbers completed familiarization and baseline tests, and constant-load hangboarding tests (including 7 seconds on and 3 seconds off at an intensity estimated to be sustained for approximately 5 minutes) under 3 conditions: (a) standardized warm-up (CON), (b) IPC, or (c) a priming warm-up (PRIME). Neuromuscular responses were assessed using the interpolated twitch technique, including maximum isometric voluntary contraction (MVC) of the finger flexors and median nerve stimulation, at baseline and after the performance trial. Muscle oxygenation was measured continuously using near-infrared spectroscopy (NIRS) across exercise. Time to task failure (Tlim) for IPC (316.4 ± 83.1 seconds) was significantly greater than CON (263.6 ± 69.2 seconds) (p = 0.028), whereas there was no difference between CON and PRIME (258.9 ± 101.8 seconds). At task failure, there were no differences in MVC, single twitch force, or voluntary activation across conditions; however, recovery of MVC and single twitch force after the performance trial was delayed for IPC and PRIME compared with CON (p < 0.05). Despite differences in Tlim, there were no differences in any of the NIRS variables assessed. Overall, despite exercise tolerance being improved by an average of 20.0% after IPC, there were no differences in neuromuscular responses at task failure, which is in line with the notion of a critical threshold of peripheral fatigue. These results indicate that IPC may be a promising precompetition strategy for rock climbers, although further research is warranted to elucidate its mechanism of action.

Chinese Feminists Face Paradoxical State Policies
Authors: Dong Yige
Published: August 2023

Struggles for women’s rights, and the state’s responses, have shifted over the history of the People’s Republic of China. In an initial period of socialist state feminism, the Chinese Communist Party celebrated “women’s liberation” and offered child-friendly services to facilitate women’s entry into the workforce. During the era of post-socialist economic modernization, services were curtailed, shifting family responsibilities back to women and reinforcing patriarchal norms. Most recently, a form of made-in-China feminism has emerged, characterized by everyday resistance to prevailing gender expectations. Now, the state is suppressing feminist activists while adopting some of their proposals into law and policy.
The Abe Assassination and Japan’s Nexus of Religion and Politics
Authors: McLaughlin Levi
Published: August 2023

The shocking murder of Japan’s former Prime Minister of Japan Shinzō Abe by a gunman motivated by anger at the politician’s ties to the controversial Unification Church sparked a massive outcry that amplified long-standing anxieties about religion in Japan. This article surveys reasons for persistent tensions between a Japanese public that tends to reject self-identifying as religious and the influence of religion-affiliated organizations on Japanese politics. It also identifies Abe’s assassination in July 2022 and local-level elections in April 2023 as potential beginning and end points of the latest moral panic about religion in Japan’s public sphere.

Objective

Thyroid eye disease (TED) is an immune-mediated disorder of the eye. Intravenous glucocorticoid (GC) is the first-line treatment for patients with active moderate-to-severe TED. However, the response rate is between 50% and 80%. There are still no simple and reliable markers of responsiveness to GC therapy. We aimed to explore the possible role of miR-146a and miR-21 as predictors of responsiveness to GC treatment in TED.

Methods

We carried out a prospective longitudinal study on 30 consecutive adult patients with active moderate-to-severe TED and eligible for GC therapy. All patients received the standard GC treatment with methylprednisolone i.v. In cases of progressive worsening of Gorman Score for diplopia or with duction restriction <30° in at least two consecutive controls, patients also underwent orbital radiotherapy. Response to GC treatment was defined as a decrease of two or more points in the clinical activity score (CAS) or CAS <4/10 at 24 weeks. Circulating miRNAs were extracted from patients’ serum and quantified by real-time PCR.

Results

Twenty-three (77%) patients responded to GC. Thyroid surgery, higher CAS, greater proptosis and higher pre-treatment circulating levels of miR-146a emerged as predictive factors of responsiveness to GC. A ROC analysis revealed that miR-146a could predict responsiveness to GC with a positive predictive value of 100%.

Conclusion

This is the first study investigating the role of pre-treatment circulating miR-21 and miR-146a to predict responsiveness to GC in TED. miR-146a emerged as a simple, objective, new marker of GC sensitivity that could be used to avoid ineffective administration of GC therapy to TED patients.
Rationale behind phosphate therapy to modulate the gut microbiome and protect against surgery-related infection
Authors: Alverdy John C
Published: August 2023

Despite major advances in infection control and the ever-increasing use of broader-spectrum antibiotics in surgery, postoperative infections continue to occur under the best of care and in the best institutions. Postoperative infections, also termed surgical site infections (SSIs), can range from superficial wound infections to deep organ space infections. SSIs can be superficial and only require medical treatment (i.e. antibiotics), whereas others such as deep organ space infections resulting from an anastomotic leak can require multiple surgeries leading to sepsis and occasionally shock and death. Many if not most stakeholders in the field including surgeons, infectious disease specialists, infection control nurses, etc., in general, advocate the use of prophylactic antibiotics and the enforcement of greater levels of sterility, reasoning that all postoperative infections must arise from some type of direct contamination event. In this article, the alternative view is presented that today, in the era of mandated asepsis protocols, enhanced recovery programs, and enforcement of prophylactic antibiotics in all cases, many if not most postoperative infections and SSIs occur from pathogens endogenous to the patient and not from sources exogenous to the patient. It is also suggested that applying broader antibiotic coverage in elective surgery is neither an evolutionarily stable strategy nor inexorable in the context of emerging knowledge in the field of gut ecology. Here this concept is reviewed and the rationale behind using agents that preserve the gut microbiome and attenuate pathogen virulence in lieu of applying broader-spectrum antibiotics and greater levels of sterility.
Male minipuberty in human and non-human primates: planting the seeds of future fertility

Published: August 2023

In brief

Minipuberty is a transient activity period of the hypothalamic–pituitary–gonadal axis in the postnatal and infant period including surging serum concentrations of reproductive hormones. Increasing evidence points to an important role of this period for maturation of the testes and thereby for male reproductive function.

Minipuberty is a transient activity period of the hypothalamic–pituitary–gonadal (HPG) axis in the postnatal and infant period in humans and non-human primates. Hallmarks of this period are surging serum concentrations of reproductive hormones. While in females, the role of minipuberty seems to be dispensable for future fertility, in males, it is significantly associated with reproductive function in later life. In males, this activity period promotes further masculinization, including testicular and penile growth, as well as completion of testicular descent if not already achieved at birth. At the testicular level, both, somatic and germ cells undergo proliferation and partial maturation during this period. Minipuberty is thought to prime male gonadal tissue for subsequent growth and maturation. Notably, perturbed or absent minipuberty is associated with reduced male reproductive function in adulthood. While the sustained HPG axis activity during adulthood is known to control reproductive function, minipuberty appears to be a prerequisite for obtaining full male reproductive function in later life, thereby determining future fertility potential, i.e. the ability to father a child. This review maps the role of male minipuberty for reproductive function and presents suitable animal models to study minipuberty. Also, it describes the development and maturation of testicular cell types, discusses short- and long-term effects of minipuberty and highlights future research perspectives.
Metafonia e inflexão vocálica na história do português. Breve comparação com algumas línguas ibero-românicas
Authors: Carvalho Maria José
Published: August 2023

Tendo em conta os testemunhos que foi possível obter na documentação notarial medieval de uma região centro-litoral portuguesa, tentar-se-á traçar a cronologia de alguns fenómenos de alteração do timbre das vogais tónicas do português (em particular da metafonia e da inflexão vocálica), cujas atestações se têm revelado escassas nos manuais de Fonética histórica, dicionários etimológicos e outro tipo de obras lexicográficas desta língua românica. A pesquisa baseou-se num corpus constituído por 153 documentos notariais autênticos, situados entre os séculos xiii e xvi, oriundos dos fundos do mosteiro de Santa Maria de Alcobaça (IAN-TT, Lisboa, 1.ª e 2.ª incorporações), por mim própria transcritos, de acordo com o respeito escrupuloso pelo manuscrito (Carvalho 2017). Assim, é propósito deste estudo fornecer alguns dados que ajudem a esclarecer por que motivo a metafonia e a inflexão vocálica não atingiram de igual modo os mesmos itens lexicais do português, do galego, do asturiano e do castelhano, ao longo do seu devir temporal. Para além de as cronologias nos poderem informar sobre o rumo e o ritmo da mudança, apontam, igualmente, para a importância da existência de um continuum na história das línguas ibero-românicas, acentuando a interdependência de fatores fonológicos, prosódicos, semântico-lexicais, contextuais e discursivos, no processo de difusão em causa.

Published: August 2023

The Ingul Megablock of the Ukrainian Shield is an area of mostly Paleoproterozoic continental crust located between the Dniester-Buh and Middle Dnieper Archean cratons. Its central part is occupied by the Korsun-Novomyrhorod anorthosite-rapakivigranite massif, which is 1757—1740 Ma, and the Novoukrainskyi massif, which is 2037—2034 Ma. A wide range of granitoids (biotite, garnet-biotite, hypersthene-garnet-biotite porphyry, trachytoid granites, granosyenites, and quartz syenites) participates in the geological structure of the Novoukrainskyi massif; medium and basic rocks of the monzonite series (quartz monzonites, monzonites, monzodiorites) play a significantly smaller role, gabbromonzonites) and gabroids (norites and gabbronorites). The article presents the results of the optical-microscopic study of the internal structure of zircon crystals and uranium-lead isotopic dating of monazite from trachytoid granite (sample Bo-1) and from the xenolith of giant-grained biotite-hypersthene granite (sample Во-2a) of the Novoukrainskyi massif, exposed by the Voynivskyi block stone. For trachytoid granite, sample Bo-1, an age of 2035.3 ± 2 Ma was obtained, for the age of monazite from a xenolith of coarse-grained granite, sample Bo-2a, we take the weighted average age value according to the 207Pb/206Pb isotopic ratio —2035.2 ± 1.8 Ma. Isotopic age values for monazites from trachytoid granite and coarse-grained granite xenolith expanded in the Voynivskyi block stone quarry completely coincide with the results of determining the age of gabroids (according to zircon) and granitoids according to monazite: 2037.4 ± 0.6 million years and 2034.8 ± 0.6 million years, respectively. Thus, the time of formation of the crystalline rocks of the Novoukrainskyi massif (2037—2034 Ma) completely coincides with the time of formation of granitoids of the Kirovohrad complex (2040—2020 Ma), which, taking into account the anatectic nature of the granitoids of both the Novoukrainskyi and Kirovohrad complexes, gives grounds for uniting the granitoids both complexes into one, for example, the Kropyvnytskyi complex, leaving only habroids as part of the Novoukrainskyi complex.
Die Hungerunruhen in Hamburg im Juni 1919 - eine zweite Revolution?
Authors: Schulte-Varendorff Uwe
Published: August 2023

Die Niederlage des Deutschen Kaiserreichs, gleichbedeutend mit dem Ende des Ersten Weltkriegs, war im November 1918 besiegelt. Die innenpolitischen Verhältnisse in Hamburg waren auch nach Abschluss der anschließenden revolutionären Phase alles andere als stabil. Einerseits waren sie geprägt von militanten Auseinandersetzungen zwischen radikalen Gruppierungen, andererseits bestimmten weiterhin Hunger und Not den Alltag der Bevölkerung. Dies war der Nährboden für einen bisher nur recht wenig beachteten kurzen Abschnitt der Geschichte der Freien und Hansestadt Hamburg, nämlich die Ende Juni 1919 in der Stadt ausbrechenden „Sülze-“ bzw. „Hungerunruhen“.

Die Aufdeckung von skandalösen Herstellungs- und Verarbeitungsmethoden eines Sülzefabrikanten führte zu Aufruhr im gesamten Stadtgebiet. Diese – allerdings nur wenige Tage andauernden – bürgerkriegsähnlichen Verhältnisse waren der Anlass für den Einmarsch von Reichswehrtruppen unter General Paul von Lettow-Vorbeck. Die Hintergründe, der Ablauf und die Auswirkungen der „Hungerunruhen“ werden in der vorliegenden Arbeit untersucht und dargestellt.
Die politische Religion
Authors: Schütz Paul , Hering Rainer
Published: August 2023

Der vierte Band der "Hamburger Historischen Forschungen" umfasst in erster Linie die Edition eines unveröffentlichten Textes. Autor ist der Theologe Prof. Dr. Dr. Paul Schütz (1891–1985), der von 1940 bis 1952 Hauptpastor an der Hamburger Hauptkirche St. Nikolai war und zugleich als hauptamtlicher Dozent und später als Professor der Theologie an der Kirchlichen Hochschule Hamburg lehrte. Er gehört zu den ersten, die ein Konzept der politischen Religion entwickelten. Sein 1935 verfasster Beitrag konnte damals nicht publiziert werden. Heute ist eine Edition dieses Beitrages zum einen wichtig für die Theologie- und Kirchengeschichte. Zum anderen gibt es seit einigen Jahren in der historischen Forschung eine intensive Diskussion über die in den Dreißigerjahren des 20. Jahrhunderts entwickelte Interpretation des „Dritten Reiches“ als „politische Religion“. Dieses Modell, das Diktaturen, insbesondere den Nationalsozialismus, als „politische Religion“ versteht, wird im Allgemeinen Eric Voegelin und Raymond Aron zugeschrieben, die ihre Ansätze 1938 bzw. 1939 publizierten. Dass Paul Schütz schon drei bzw. vier Jahre zuvor eine solche Konzeption entwickelt hatte, war bis vor Kurzem nicht bekannt. Die vorliegende Edition kann daher neue Impulse für die Debatte über die Geschichte und Tragfähigkeit dieses Ansatzes geben und sie inhaltlich bereichern. Die Edition wurde herausgegeben und eingeleitet von Rainer Hering.

Gas-phase transmission electron microscopy is an essential tool for elucidating the mechanisms involved in the synthesis of functional materials. Here, we review the latest developments in understanding the growth of novel nanostructural materials afforded by following the process in situ in electron microscopes. Particular focus is on investigations of catalyzed growth of one-dimensional carbon-based and semiconductor nanostructures, while other types of nanocrystal and epitaxial crystal growth are briefly addressed. Also discussed are how these methods have been employed to answer critical questions about the growth mechanisms as well as to bring insight into the relationships between synthesis parameters and materials properties.

TiO2 nanoparticles obtained by microwave-assisted hydrothermal synthesis were subjected to facile post-processing based on vacuum annealing. The resulting defective (TiO2-x) material showed extended light absorption in the visible range, enhancing sunlight compatibility. Structural and optical characterization point to the arising of an Urbach tail as the main reason. TiO2-x was then employed as photocatalyst for the inactivation of ciprofloxacin, an emerging environmental threat and source of antimicrobial resistance, under sunlight. TiO2-x performed significantly better than its parent compound and mechanistic analysis of the degradation pathway indicates that this material is a promising candidate for solar treatment of fluoroquinolones residues in water.

Middle schoolers’ book selection and reasons for discontinuing reading
Authors: Karatay Halit , Tezel Kadir Vefa , Demirel Ahmet
Published: August 2023

In this qualitative research we employed the case study method to identify the factors that affect Turkish fifth to eight graders’ selection of books to read and the reasons that cause them to stop reading the books they have selected. To identify those factors and reasons, data were collected from a total of 32 participating students who were selected using stratified purposive sampling. A group was formed for each grade. Each grade group included 8 students who borrowed books from public libraries and voluntarily participated in the study. The participants were interviewed using open-ended questions. Interviews revealed that in selecting books to read, the students considered theme, genre, and structural features such as title, cover design, author, publisher, and recommendations made by peers, teachers, and family members as criteria. The students also stated that the events and themes in the books, language features, font size, insufficient time to read, and the library’s requirement to return a book in 15 days were the reasons to give up reading a selected book.

Authors: Seherrie A.C. , Mawela A.S.
Published: August 2023

Education in the 21st century has had an evolutionary impact on teachers’ teaching approaches in South African schools. Teachers are continuously faced with challenges in improving teaching and learning approaches in response to addressing the particular needs of a diverse group of learners. With this article we aimed to explore life orientation teachers’ use of a cooperative teaching and learning approach to enhance learners’ performance in secondary schools. A qualitative research design was employed with an interpretivist-constructivist paradigm to obtain the views of the secondary teachers who responded via face-to-face interviews. We employed purposive convenient sampling of seven (N = 7) teachers from the Northern Cape province in South Africa. Data were analysed using inductive thematic analysis and supported by the literature review and the theory underpinning this study. Findings of this study reveal that some teachers were favourably implementing cooperative teaching methods, despite the lack of resources and many other challenges they faced. School managers must infuse cooperative learning in their daily teaching praxis to ensure that teachers become confident and continuously employ this approach.

Antecedentes: El noreste de México, estados de Coahuila, Nuevo León y Tamaulipas, constituye una región heterogénea que incluye sierras, planicies continentales y llanuras costeras con una infinidad de ambientes, substratos geológicos y gradientes altitudinales que favorecen la presencia de una rica biodiversidad. No existe una síntesis que documente la diversidad florística de esta región.
Preguntas: ¿Cuál es la magnitud de la diversidad de plantas vasculares en el noreste de México?, ¿Cuáles son las familias y géneros con mayor número de especies?, ¿Cómo se distribuye geográficamente esta riqueza florística en toda la región y cuáles son sus elementos más característicos?
Especies de estudio: 7,088 especies de plantas vasculares.
Sitio de muestreo: estados de Coahuila, Nuevo León y Tamaulipas.
Métodos: Se consultó literatura florística-taxonómica sobre la flora de la región y bases de datos de ejemplares para hacer un análisis espacial de la biodiversidad usando celdas de 1° de longitud y latitud. Se calculó la riqueza y el endemismo en la región, los estados y las celdas.
Resultados: Para el noreste de México se reportan 7,088 especies de plantas vasculares, de las cuales 1,767 son endémicas de México.
Conclusiones: El noreste de México registra una diversidad florística particularmente interesante y compleja, debido a que su territorio se ubica primordialmente fuera del neotrópico y porque constituye el límite boreal para muchos elementos de la flora de México.
Comunicación en pandemia. Implicaciones tecnológicas y simbólicas en la experiencia de jóvenes universitarios
Authors: Olmedo-Neri Raul Anthony
Published: August 2023

La comunicación, sus estructuras tecnológicas y sus valores simbólicos se dislocaron por la digitalización de la vida cotidiana como consecuencia de la pandemia. Este contexto impactó la experiencia juvenil universitaria, por lo que resulta importante analizar los cambios socioculturales en cuanto al uso de las Tecnologías de la Información y la Comunicación (TIC) de un grupo de universitarios, el tiempo de conexión, el dispositivo utilizado y su relación con el espacio doméstico durante la pandemia en México. Para ello se articula un marco teórico desde los Estudios Culturales para analizar la relación jóvenes-tecnología durante la pandemia e identificar su relevancia dentro de la experiencia juvenil contemporánea.La metodología utilizada tiene un enfoque mixto con un grupo de estudiantes universitarios mexicanos de la licenciatura en Comunicación (N=29), donde se empleó un formulario y un grupo focal para recuperar sus experiencias. Los resultados muestran que la pandemia suprimió las fronteras entre lo íntimo y público, generando procesos de negociación entre los miembros de la familia sobre el uso de dispositivos y los espacios domésticos. Además, las actividades educativas, familiares y sociales incrementaron el tiempo de conexión de jóvenes universitarios, pero además resignificaron los espacios domésticos por el solapamiento de actividades. Finalmente, se reconoce que la habitación de los participantes se vuelve el espacio estratégico para la experiencia juvenil en la pandemia porque las actividades universitarias, familiares y de socialización se desarrollaron en un mismo lugar. Para ello se articula un marco teórico desde los estudios culturales con la finalidad de evidenciar la relevancia de las TICs e Internet en el condición y experiencia juveniles, las cuales durante la pandemia ampliaron sus funciones y permitieron mantener y crear la socialidad de las y los jóvenes mexicanos. La metodología empleada tiene un enfoque mixto con un grupo de estudiantes universitarios mexicanos (N=29), donde se emplearon bitácoras y un grupo focal. Entre los resultados se destaca que las actividades educativas han incrementado el tiempo de conexión, pero redistribuido su finalidad. Finalmente, se reconoce que la habitación de los participantes se vuelve el espacio estratégico desde el que se articula la experiencia juvenil en la pandemia al solaparse las actividades escolares, familiares y de socialización en un mismo lugar.
Federaciones deportivas de España, recursos comunicativos e impacto de la Covid-19

Published: August 2023

Las federaciones deportivas son consideradas de utilidad pública en España. En sus funciones tiene un peso especial la comunicación y la organización de eventos, por lo que la aparición de la pandemia, al igual que ocurrió en otros sectores, supuso una adaptación estructural y de gestión comunicativa que puso a prueba a estas organizaciones. En este artículo se propone analizar esta realidad en las federaciones deportivas de carácter nacional y regional que operan en España, haciendo un estudio de su realidad organizacional y comprendiendo el impacto que la Covid-19 ha tenido en su comunicación. Se ha diseñado un cuestionario dirigido a los directores/as de comunicación y responsables de la misma y se han llevado a cabo una serie de entrevistas en profundidad a través de las cuales se realizarán una radiografía sobre el panorama comunicativo de las federaciones deportivas en la era post-covid. Tras el análisis de los datos recabados se concluirá que la realidad de las federaciones nacionales y regionales es bien distinta en el ámbito de la comunicación; sus recursos (humanos y económicos) son muy diferentes y esto se traslada a sus estructuras internas para gestionar la comunicación. Por otra parte, el impacto de la Covid-19 ha sido contundente en estas instituciones, no sólo en cuanto a cambios en los formatos de gestión de comunicación, sino también en lo referente a uso de tácticas, técnicas y herramientas.

Este texto ilustra el rol de los medios de comunicación alternativos frente a la denuncia y visibilización de casos de desaparición forzada y asesinato de líderes sociales después de la firma del Acuerdo de Paz en el 2016 en el Departamento del Meta-Colombia. A partir de ello, la investigación que se relata en este artículo, pretende nombrar a los líderes, sus territorios, el rol que desempañaban en sus comunidades para enunciar las particularidades de los sujetos que aún siguen sufriendo de estas afectaciones; los posibles responsables y la relevancia que tienen los medios de comunicación alternativos en hacerlos visibles, para la construcción de memoria colectiva.
Para ello se realizó un análisis de datos de tipo documental y de contenido durante el periodo 2017-2020, que da cuenta de las diversas formas de informar y denunciar estas afectaciones. La investigación aporta en posicionar la relevancia de estos medios de comunicación alternativos en la construcción de memoria colectiva y el no olvido de estas afectaciones como hechos sociales y políticos transcendentes y que estos medios a través de narrativas multimediales a partir de diversos formatos textuales, gráficas, sonoros y fotográficos se posicionan en las plataformas virtuales visibilizando la voz de las familias y comunidades que denuncian y buscan a sus familiares que intentan reivindicar su derecho a la verdad, reparación y memoria.
Can Dialogic Narratives and Discourse Engage Online Learners?
Authors: COOK Ruth Gannon
Published: August 2023

This research gathered data from eight online courses to assess if dialogic narratives improved student interactions and retention in those courses. The framework was based on Bakhtin’s theory of dialogism grounded in the semiotic concepts of dialogic narratives (Bakhtin, 1931, 1985, 1986). Dialogic narratives were encouraged in all eight of the online courses to encourage and enlist discussions and nurture students individually and as communities of learners. The research question posed was: Can dialogic narratives be included in course discussion links of online courses, and if so, could they promote deeper engagement of online learners? The study reviewed eight undergraduate online classes of 113 students at a large university that implemented dialogic narratives over course of two years, through spring of 2019, to see if students could engage, actively participate, and complete these courses. The theoretical context or the study utilized a semiotic theoretical framework to demonstrate if and how dialogic narratives conveyed contextual information, elements of semiotic online course design, and focused on socio-cultural practices, to study how these factors could affect student learning. Using a Bakhtinian analysis, the semiotic enhancements of dialogic narratives were reviewed in each of the eight online courses and learner interactions observed and documented. The results were surprising: in all eight courses the semiotic enhancements were found to be interactive and effective. Dialogic narratives helped students to participate more actively in their online courses than simply responding to assigned discussions. The findings also revealed high completion rates for students enrolled in those online courses.

Students who struggle with writing may also struggle academically. Mobile applications play a vital and supportive role in addressing this issue. The purpose of this research is to examine mobile writing applications and to gather the opinions of teachers and experts on these applications in order to support the writing skills of 1st and 2nd-grade primary school students. In this way, the strengths and weaknesses of the existing applications will be evaluated, and a projection will be kept on the mobile writing application that should be. The researchers applied qualitative and quantitative methods. In order to reveal the needs in question, a number of applications from the Android and IOS stores were reviewed using a rubric devised by the researchers. Semi-structured interviews were conducted to gather opinions from primary school and special education teachers and subject matter experts in primary and special education. The study revealed the insufficiency of targeted applications to support writing skills, particularly regarding accessibility, audio, and visual elements. This finding emphasizes the need for new mobile applications to eliminate the limitations. This study provided vital insights into building a mobile application for addressing writing difficulties that might satisfy the needs. The results of this study include suggestions that will shed light on future research on mobile writing applications.
