REFLEXÕES SOBRE CONCEPÇÕES E PRÁTICAS DE FORMAÇÃO DA DOCÊNCIA EM MATEMÁTICA
Authors: Melo Lucas , Menezes Fabio , Mendes Daniela
Published: April 2023

Este trabalho tem o objetivo de tecer reflexões sobre concepções que permeiam a formação docente, em particular, que ensinam matemática. Trouxemos um diálogo teórico e exemplos práticos sobre uma proposta denominada de práticas docentes compartilhadas (PDC). Nos referenciamos em trabalhos que propõem uma perspectiva afirmativa acerca da formação docente em matemática, no sentido de incorporar a prática na formação docente, em contraponto a uma perspectiva negativa que tem no professor aquele que aplica um manual promovido por pesquisadores que sustentam políticas públicas dizendo o quê e como ele deve ensinar, muitas vezes pautada no que os professores não precisam saber para exercer a profissão, ao invés de se constituir a partir das demandas específicas da atuação profissional docente. Concluímos que os paradigmas de concepções trazem em si efeitos sociais e na perspectiva afirmativa percebemos a perda do “medo de errar” e do “medo da matemática” e também produz a sensação de que matemática é sim para todas as pessoas e não só para as ditas geniais. Tal perspectiva ainda produz o efeito de pertencimento, pois licenciandos conseguem se ver se formando e se desenvolvendo para uma profissão: a docência.

Published: April 2023

Este artigo apresenta uma narrativa pedagógica das autoras sobre uma de suas experiências de ensino de Matemática e de Português para estudantes da educação especial, vivenciadas no contexto do Ensino Remoto Emergencial, em função da pandemia da COVID-19. Para a produção da narrativa, as autoras se debruçaram sobre um dos materiais didático-pedagógicos que fazem parte do repositório de atividades construído como uma das ações da pesquisa “Inclusão na escola regular de tempo integral: análise e compartilhamento de práticas pedagógicas inclusivas no Ensino Remoto Emergencial”, no intuito de rememorar o “trabalho colaborativo” (FIORENTINI, 2004) que envolveu a produção desse material para um determinado estudante, bem como refletir sobre como as atividades foram apropriadas por ele e sua família. A perspectiva teórico-metodológica central do artigo consiste na abordagem narrativa (auto)biográfica em educação, referenciada nos trabalhos de Bolívar (2002), Bragança (2021), Clandinin e Connelly (2011) e Prado (2013). A narrativa pedagógica produzida pelas autoras dialoga, ainda, com estudos sobre letramento, educação matemática, educação especial e saberes docentes. Como professoras (e) pesquisadoras envolvidas tanto na produção do material em questão quanto na relação pedagógica com o estudante, as autoras buscam reconstruir narrativamente o trabalho colaborativo que realizaram, atravessado por reflexões pedagógicas que exploram os sentidos da experiência pedagógica vivenciada com o estudante, e compartilhar com seus pares as compreensões construídas acerca das possíveis relações entre educação matemática e letramento no processo de escolarização de crianças da educação especial nos anos iniciais do ensino fundamental.

Burnout, compassion fatigue and moral distress in veterinary professionals
Authors: Foote Amber
Published: April 2023

Veterinary professionals are becoming increasingly exposed to, and concerned about, burnout, compassion fatigue and moral distress. Work-related stress can have a significant impact on quality of life and contribute to poor mental health. Several studies have shown that emotional exhaustion and mental health illnesses are significantly higher among veterinary surgeons, with the rate of suicide in the veterinary profession four times the rate in the general public. There is an abundance of evidence in the human healthcare field regarding burnout, compassion fatigue and moral distress, but there is very little research in the veterinary field. This study aimed to investigate whether veterinary professionals in the UK are experiencing burnout, compassion fatigue and moral distress, identify possible contributing factors, and ascertain whether veterinary professionals are able to recognise these conditions and have the tools to deal with them. The study found that veterinary professionals showed moderate levels of burnout and compassion fatigue, despite moderate levels of compassion satisfaction. Veterinary surgeons, patient care assistants and veterinary receptionists experienced low levels of moral distress, but registered veterinary nurses experienced moderate levels of moral distress.

Published: April 2023

This study examined the length-weight relationship and condition factor of Hydrocynus forskahlii (Cuvier, 1819) in River Yobe, Northeast, Nigeria. A total of 350 fish species were collected from commercial fishermen at four landing sites (Gogaram, Dogona, Bize, Azbak) within the study area between June to November 2020. The morphometric and meristic characteristics examined could be attributed   to environmental variations (water temperature, stress, food availability, spawning ground, fishing intensity and sex). Monthly mean condition factor (1.19 ± 1.03) shows significant difference (P 0.05) during the sampling duration while highest mean condition factor was recorded in October (1.38 ± 1.15). Also change in weight of the sampled fish was caused by 77.4% change in length. A linear relationship was established with b value (1.2656) indicating a negative allometric growth pattern while correlation coefficient (r2 = 0.7775) indicated that LWR model is reliable. This study bridged literature gap on LWR and condition factor of Hydrocynus forskahlii in River Yobe, hence further research should be encouraged on the water body for sustainable utilization, decision making and policy formulation.

Published: April 2023

The effects of magnesium ion implantation and post-annealing on the photoelectric performance of a β-Ga2O3-based vertical structural Schottky photodetector (PD) were thoroughly investigated. After implantation and post-annealing, the Schottky barrier height and bandgap of the Ga2O3 surface can be slightly increased, while the dark current is significantly reduced, and the light-to-dark current ratio is immensely improved. The PD exhibited a photo-to-dark current ratio of 1733, responsivity of 5.04 mA/W, and specific detectivity of 3.979×1011 Jones under −2.6V bias, and the rise and decay times are 0.157 were 0.048 s, respectively. The large left shift of the open-circuit voltage is feasibly explained by applying the thermionic-emission diffusion theory.
Global elective breast- and colorectal cancer surgery performance backlogs, attributable mortality and implemented health system responses during the COVID-19 pandemic: A scoping review
Authors: Haribhai Sonia , Bhatia Komal , Shahmanesh Maryam
Published: April 2023

Globally, 28.4 million non-emergent (‘elective’) surgical procedures have been deferred during the COVID-19 pandemic. This study evaluated the impact of the COVID-19 pandemic on elective breast- or colorectal cancer (CRC) procedure backlogs and attributable mortality, globally. Further, we evaluated the interaction between procedure deferrals and health systems, internationally. Relevant articles from any country, published between December 2019–24 November 2022, were identified through searches of online databases (MEDLINE, EMBASE) and by examining the reference lists of retrieved articles. We organised health system-related findings thematically per the Structures-Processes-Outcomes conceptual model by Donabedian (1966). Of 337 identified articles, we included 50. Eleven (22.0%) were reviews. The majority of included studies originated from high-income countries (n = 38, 76.0%). An ecological, modelling study elucidated that global 12-week procedure cancellation rates ranged from 68.3%–73%; Europe and Central Asia accounted for the majority of cancellations (n = 8,430,348) and sub-Saharan Africa contributed the least (n = 520,459). The percentage reduction in global, institutional elective breast cancer surgery activity ranged from 5.68%–16.5%. For CRC, this ranged from 0%–70.9%. Significant evidence is presented on how insufficient pandemic preparedness necessitated procedure deferrals, internationally. We also outlined ancillary determinants of delayed surgery (e.g., patient-specific factors). The following global health system response themes are presented: Structural changes (i.e., hospital re-organisation), Process-related changes (i.e., adapted healthcare provision) and the utilisation of Outcomes (i.e., SARS-CoV-2 infection incidence among patients or healthcare personnel, postoperative pulmonary complication incidence, hospital readmission, length of hospital stay and tumour staging) as indicators of health system response efficacy. Evidence on procedure backlogs and attributable mortality was limited, partly due to insufficient, real-time surveillance of cancer outcomes, internationally. Elective surgery activity has decreased and cancer services have adapted rapidly, worldwide. Further research is needed to understand the impact of COVID-19 on cancer mortality and the efficacy of health system mitigation measures, globally.

Published: April 2023

Background

While surgical simulation is regularly used in surgical training in high-income country settings, it is uncommon in low- and middle-income countries, particularly for surgical training that primarily occurs in rural areas. We designed and evaluated a novel surgical simulator for improving trachomatous trichiasis (TT) surgery training, given that trichiasis is mostly found among the poorest individuals in rural areas.

Methodology/Principal findings

TT surgery programs were invited to incorporate surgical simulation with a new, high fidelity, low-cost simulator into their training. Trainees completed standard TT-surgery training following World Health Organization guidelines. A subset of trainees received three hours of supplemental training with the simulator between classroom and live-surgery training. We recorded the time required to complete each surgery and the number of times the trainer intervened to correct surgical steps. Participants completed questionnaires regarding their perceptions. We also assessed trainer and trainee perceptions of surgical simulation training as part of trichiasis surgery training.

22 surgeons completed standard training and 26 completed standard training plus simulation. We observed 1,394 live-training surgeries. Average time to first live-training surgery completion was nearly 20% shorter the simulation versus the standard group (28.3 vs 34.4 minutes; p = 0.02). Trainers intervened significantly fewer times during initial live-training surgeries in the simulation group (2.7 vs. 4.8; p = 0.005). All trainers indicated the simulator significantly improved training by allowing trainees to practice safely and to identify problem areas before performing live-training surgeries. Trainees reported that simulation practice improved their confidence and skills prior to performing live-training surgeries.

Conclusions

A single high-fidelity surgical simulation session can significantly improve critical aspects of initial TT surgeries.
Did place-based industrial policy promote regional economic growth? ---- Evidence from China
Authors: Liu Jianzhao , Li Na , Du Xueli
Published: April 2023

Whether the place-based industrial policy promotes regional economic growth is a hot issue in the field of regional industrial economic practice. As a major national strategy in China, the Beijing-Tianjin-Hebei industrial coordinated development policy has been implemented more than 8 years. Verifying its effect on regional economic growth and revealing the policy action path will help to further optimize the policy implementation process through feedback. In this paper, the policy effect and its differentiation are empirically studied from ‘quality’ and ‘quantity’ respectively by establishing a growth model using the Dual Differences method. The results show that the Beijing-Tianjin-Hebei industrial coordinated development policy improves total factor productivity by 2.26% in terms of ‘quality’, and reduces GDP growth rate by 4.65% in terms of ‘quantity’. For the different region, the GDP growth rate increased by 1.28%, while total factor productivity decreased by 2.63% in Beijing, the GDP growth rate decreased by 3.17% and total factor productivity increased by 0.87% in Tianjin, and the GDP growth rate increased by 2.56% and total factor productivity increased by 1.58% in Hebei. The policy is mainly realized by fixed asset investment, capital deepening degree and enterprise scale expansion, while the effect of labor input, R&D investment and enterprise number is not significant. The policy is to give full play to the driving role of fixed asset investment such as "new infrastructure", increase investment in labor and research and development in the region, strengthen the construction of a competitive market environment, and stabilize the ‘quality’ and ‘quantity’ to further release policy dividends.
CHAC1 inactivation is effective to preserve muscle glutathione but is insufficient to protect against muscle wasting in cachexia

Published: April 2023

Muscle wasting is one of the main characteristics of cachexia associated with cancer and other chronic diseases and is often exacerbated by antineoplastic agents. Increased oxidative stress is associated with muscle wasting, along with depletion of glutathione, the most abundant endogenous antioxidant. Therefore, boosting endogenous glutathione has been proposed as a therapeutic strategy to prevent muscle wasting. Here, we tested this hypothesis by inactivating CHAC1, an intracellular glutathione degradation enzyme. We found CHAC1 expression is increased under multiple muscle wasting conditions in animal models, including fasting, cancer cachexia, and chemotherapy. The elevation of muscle Chac1 expression is associated with reduced glutathione level. CHAC1 inhibition via CRSPR/Cas9 mediated knock-in of an enzyme inactivating mutation demonstrates a novel strategy to preserve muscle glutathione levels under wasting conditions but fails to prevent muscle wasting in mice. These results suggest that preserving intracellular glutathione level alone may not be sufficient to prevent cancer or chemotherapy induced muscle wasting.
ECG signal classification in wearable devices based on compressed domain
Authors: Hua Jing , Chu Binbin , Zou Jiawen , Jia Jing
Published: April 2023

Wearable devices are often used to diagnose arrhythmia, but the electrocardiogram (ECG) monitoring process generates a large amount of data, which will affect the detection speed and accuracy. In order to solve this problem, many studies have applied deep compressed sensing (DCS) technology to ECG monitoring, which can under-sampling and reconstruct ECG signals, greatly optimizing the diagnosis process, but the reconstruction process is complex and expensive. In this paper, we propose an improved classification scheme for deep compressed sensing models. The framework is comprised of four modules: pre-processing; compression; and classification. Firstly, the normalized ECG signals are compressed adaptively in the three convolutional layers, and then the compressed data is directly put into the classification network to obtain the results of four kinds of ECG signals. We conducted our experiments on the MIT-BIH Arrhythmia Database and Ali Cloud Tianchi ECG signal Database to validate the robustness of our model, adopting Accuracy, Precision, Sensitivity and F1-score as the evaluation metrics. When the compression ratio (CR) is 0.2, our model has 98.16% accuracy, 98.28% average accuracy, 98.09% Sensitivity and 98.06% F1-score, all of which are better than other models.
Analysis of stereopsis and fusion in school-aged children with reduced visual acuity due to refractive error
Authors: Joo Hye Jun , Choi Dong Gyu
Published: April 2023

Purpose

In patients with strabismus, the stereopsis and Worth 4-dot (W4d) tests have often been used to evaluate whether sensory fusion is achieved. However, if patients face difficulties undergoing the Titmus or W4d test because of poor visual acuity (VA) due to refractive error abnormalities, the results of these tests cannot be appropriately interpreted. Therefore, we evaluated the correlation between distance uncorrected VA (UCVA) and sensory status in children with reduced VA due to refractive error abnormalities to identify the effects of refractive errors on sensory test results.

Methods

We retrospectively reviewed the medical records of 195 children with reduced VA with VA improvement ≥ 20/25, Titmus stereoacuity ≤ 50 arcsec, and fusion in the W4d result after refractive error correction with spectacles. We evaluated the correlation between distance UCVA in logMAR and sensory status measured by the near Titmus stereotest and distance W4d test. Additionally, the minimum required UCVA for interpreting Titmus or W4d results was assessed using a receiver operating characteristic (ROC) curve.

Results

The UCVA showed a marginal but non-significant correlation with Titmus stereoacuity (p = 0.053) and a significant correlation with fusion in W4d (p < 0.001). The ROC curve analysis showed an optimal cut-point value of VA required for interpreting the results of W4d test as 0.3 logMAR (20/40 in Snellen acuity).

Conclusions

Correcting refractive error in advance may help appropriately interpret sensory status in school-aged children with reduced VA due to refractive error abnormalities.

With the 4th Industrial Revolution, the utilization of unmanned aircraft systems is increasing day by day in various fields. However, unmanned aircraft systems are vulnerable to functional errors due to their unique characteristics, such as remote control and automatic flight. In the event of an accident, the system operator and the general public may be injured, and the system manufacturer may be disadvantaged by the Product Liability Act. In addition, with the establishment of international standards related to risk management and functional safety, such as ISO/IEC/IEEE 16085, IEC 61508, and ARP4761, risk analysis and countermeasures have become essential when developing systems. It is time to ensure functional safety at the conceptual design phase to protect public safety and manufacturers' interests. This study reviews international standards to confirm the importance of identifying functional safety hazards and managing requirements. In addition, it also analyzes the accident investigation reports of the UK AAIB to identify hazards of unmanned aircraft systems and derive safety requirements.

Published: April 2023

Following the adoption of Roundup Ready crops, glyphosate spraying frequency increased, while the use of other herbicide modes of action was neglected. Herbicide-resistant biotypes were reported in three major Conyza species in Brazil, including Conyza bonariensis, increasing growers’ bottom line. Considering that leaf surface structures affect proper herbicide deposition, uptake, and performance, this study aimed to characterize epicuticular surface components in glyphosate-resistant (R) and -susceptible (S) C. bonariensis. Conyza spp. seeds were collected in 36 locations in Brazil, and plants were subjected to resistance screening tests by spraying glyphosate at 720 and 1440 g ae ha-1 (0.5X and 1X the label recommended rate, respectively). For resistance level characterization, C. bonariensis biotypes with contrasting responses were selected for glyphosate dose-response assays. Leaf tissues for epicuticular surface analysis were harvested from newly-obtained R and S biotypes at two growth stages. Histological cuts were made on a leaf area of 25 mm² with a blade. Samples were fixed in Karnowsky solution, gradually changed to 100% ethanol, critical-point dried with CO2, and coated with gold, followed by stomatal and trichome density quantification using scanning electron microscopy. Results indicated a poor control with glyphosate in 33 of 36 Conyza spp. biotypes, and a high (31.5) resistance factor was calculated after dose-response trials. Leaf surface analysis indicated that C. bonariensis leaves are amphistomatic and exhibit tectorial trichomes. A higher number of trichomes and altered stomatal density (number.mm²) were quantified in R compared to the S counterpart, potentially reducing glyphosate uptake and effectiveness.

Authors: Soingam Tanyapohn , Srithaworn Moltira
Published: April 2023

Dracaena cochinchinensis (Lour.) S.C. Chen (Chandaeng) is an important traditional medicinal plant used in ancient Thai household remedies. This research focused on investigating the biological properties, including the antibacterial, anti-tyrosinase, antioxidant activities, and phytochemical characteristics of crude Chandaeng extracts. Dried Chandaeng heartwood powder was extracted using ethanol, methanol, and deionized water. The antibacterial activities of the extracts were then tested against skin pathogens, including Cutibacterium acnes (DMST14916), Staphylococcus epidermidis (TISTR518), and Staphylococcus aureus (TISTR321). The ethanolic extract showed antibacterial activity. In a time-kill assay, all bacteria were completely killed after being exposed to it, while the cell membranes were found to have leaked when viewed under a scanning electron microscope. Antioxidant potential was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2¢-azino-bis -3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assays. According to the findings, the crude ethanolic extract of Chandaeng showed the highest level of antioxidant activity. Furthermore, the potential of the extract to treat skin hyperpigmentation by inhibiting tyrosinase, an important melanin synthesis enzyme, was determined and the ethanolic extract was found to be an anti-tyrosinase agent. Finally, the crude ethanolic extract showed the highest total phenolic compound and flavonoid content. In conclusion, crude Chandaeng extract showed significant potential in activity against skin pathogenic bacteria, antioxidant activity, and tyrosinase inhibition. These properties of the extract could be applied to skincare cosmetics.

Published: April 2023

Since there are inconsistent findings on the influence of entrepreneurial orientation on business performance, we aim to develop a conceptual model to explain how an entrepreneurial orientation has the potential to enhance business performance. We develop a concept of culinary-gastronomic value advantage as mediation for entrepreneurial orientation to improve business performance effectively. We examine the model by involving 241 owner-managers of micro and small-sized enterprises in the food industry, whose results were analyzed using SEM-AMOS software. This studyâ€™s results indicate that the culinary-gastronomic value advantage derived from the Service-Dominant Logic (SDL) theory is an acceptable solution as mediation for entrepreneurial orientation and performance. Another important finding is that the entrepreneurial orientation and culinary-gastronomic value advantages are highly dependent on the level of risk consciousness on the competitive pressures that occur in the market. This study brings several theoretical implications to service-dominant logic theory, particularly on value accentuation in the form of culinary-gastronomic value advantage for enhancing performance.
Knowledge Management and Blockchain Technology for Organizational Sustainability
Authors: Frozza Talita , Lima Edson Pinheiro de , Costa Sérgio Eduardo Gouvêa da
Published: April 2023

Goal: This paper develops a conceptual model representing existing relations between blockchain, knowledge management, and sustainability.
Design/Methodology/Approach: A systematic literature review was carried out, and a total portfolio of 43 articles was obtained. These articles were then analyzed using the content analysis technique.
Results: Identifying the existing relationships between blockchain and knowledge management and between knowledge management and sustainability was possible. This information allowed the elaboration of the conceptual model, which resulted in the identification of the roles of each theme when related to each other.
Limitations of the investigation: The limitations refer to the diversity and complexity of the themes, which made it necessary to limit the search for articles to two databases; the temporality of the research due to the evolution of the blockchain; and the failure to consider the risks arising from the adoption of technology and the negative aspects of the relationships between the themes.
Practical Implications: With this article, companies studying blockchain adoption, looking for ways to improve knowledge management, or seeking to adjust their impacts on sustainability, can find information that helps in decision making.
Originality/ Value: This article proposes a conceptual model that explains the relationship between three current and increasingly essential topics for organizations. To this end, it seeks to identify in the literature how the application of the first (blockchain) improves the execution of the second (knowledge management) and how this impacts the third (sustainability).

Published: April 2023

Among the many paths in life on which God places man there is undoubtedly the one that leads to the heights of holiness. It is not always easy, but certainly beautiful. Delighted by this beauty of God’s plans, Brother Jerzy Lakomiak united his paths with the Master’s dogs. Reading and responding to God’s call, he responded with his life by taking up the path of the evangelical counsels: chastity poverty and obedience following the example of St. Francis of Assisi. His love for God, the Blessed Mother, holy poverty, quiet and humble service, and a life of prayer, first in his native country and then for half a century on Argentine soil, made it possible that today among his confreres and those who knew Brother George, he is spoken of as one who exemplarily fulfilled themission the Risen Lord entrusted to him.
Zastosowanie teorii performansu Diany Taylor w badaniach nad kultem Świętej Śmierci w Meksyku

Published: April 2023

The aim of the article is to analyse the latest trends in Mexican cult of Santa Muerte (the Saint Death) using the terms proposed by Diana Taylor in her theory of per­formance. The concepts of the archive and the repertoire are especially functional for describing contemporary hybrid religious phenomena which undergo constant transfor­mations and which origins are diverse. Application of mentioned terms permits to capture the sources of those metamorphoses and their religious and cultural background. This allows to demonstrate how the unrelated archives convert into the repertoire of practices connected with the cult of the Saint Death. These practices are not limited only to the ones representing strictly religious character but they include various activities – performanc­es of everyday life – for which Santa Muerte is a certain type of context, background or reference point.

近年，社會出現有關年輕人「躺平」的討論，指年輕新一代不願找工作、不願勤奮加班、不規構未來。教育局局長楊潤雄亦曾在網誌撰文表示憂慮，批評「躺平這種消極的人生心態，長遠會窒礙社會的進步」。 不過，根據香港政府統計處2021年收入及工時按年統計調查報告， 2021年5月至6月，15至24歲及25至34歲受訪者每周的工作時數中位數分別為44.3及42小時，比亞洲其他國家要高；而2022年4至6月，20至24歲及25至29歲的勞動人口參與率分別為53.5%及87%，後者更是所有年齡組別中第二高（僅次於30至34歲年齡組別），反映年輕人並沒有不願意長時間工作和就業，與成年人無異。 另外，根據中大亞太研究所於本年四月進行的一項調查，超過半數受訪者認為香港社會並沒有足夠機會與年輕一代向上流動，更有六成半受訪者認為，現時香港向上流動的機會比過去10年要少。 在是次研究中，發現有不少手持大學文憑的畢業生甫踏入社會，便從事三行、保安、飲食業等藍領工種，以體力勞動換取更高薪酬。文職的工作機會雖不算難找，但對於畢業生來說，待遇多不及前者；初入職場的年輕人便要忍受長工時以換取較可觀的薪金，更因長期體力勞動及工作環境惡劣，導致工傷或患上職業病，造成不可逆轉的傷害；選擇白領工作的年輕人則花空餘時間研究創業路向，望有天可擺脫低工資、長OT的工作常態。 年輕人是社會重要的群體，促進社會不同面向的發展和進步。勞工議題，正正就是影響年輕人最深遠的問題。不過，社會一般會把青年遇到的問題視為過渡性現象，隨著他們成長而消失。坊間少有深入討論，以致一般年輕人以為工作的沉重是理所當然，對自身的勞工權益鮮有認識。 上述所提及的年輕人工時長的狀況，窒礙他們在成長階段的探索，因長工時影響反心健康、無法進修、交結朋友、和家人相處及了解自我。工時長等問題在港是老生常談，卻是待解決的重要議題。香港人多年來一直受長工時的困擾，回顧香港的工時政策，卻未見突破。由勞顧會於2018年宣布推出「11個行業工時指引」，距今已4年，仍未見進展。更何況，指引的條文亦不適用於大部份長工時的打工仔女，例如只保障月薪不超過1.1萬元作為界定工資較低的基層僱員的工資線等規定。可見，像過往一樣，政府及商界等對標準工時並不持開放態度。 誠然，參考不同地區及國家的工時政策，香港則顯得相當落後。中國、日本、台灣、韓國及新加坡均有明確法例規管工時，如超時工作的補水機制、每天工作8小時作為標準工時等。如香港政策要推行工時相關的政策，大有參考例子。本報告亦整合及分析了上述地區的工時政策，有助了解其他地區的勞工法例。 是次研究探討了現行的工時政策下香港年輕僱員的工作現況。透過深入訪談及問卷調查，發現長工時與生理、心理、社交及家庭關係的影響，以及就研究結果提倡相應的政策改革，讓社會大眾及年輕人自身了解他們的勞動現況，剖析處境並提出有效的改善方針。

Objectives

Unani physicians have suggested a wide range of anti-dermatophytic remedies, although the scientific evidence is scarce. Thus, the efficacy and safety ofTerminalia chebulaRetz. fruit powder mixed with vinegar was compared with terbinafine hydrochloride 1% cream in the treatment of tinea corporis in order to establish the non-inferiority of test drugs.

Methods

The primary outcome measures were change in the presence or absence of hyphae on KOH mount test, change in pruritus severity assessed on 100 mm VAS and change in physician’s global assessment. Secondary outcome measure was change in the dermatology life quality index (DLQI). Hemograms, serum creatinine, serum bilirubin, and random blood sugar levels were measured at the baseline and after treatment to ensure the safety of the interventions.

Results

A per-protocol analysis was done on 40 participants (21 in the test group and 19 in the control group). The observed differences in the primary and secondary outcomes between the test and control groups were greater than the non-inferiority margin, signifying that the test drugs were not inferior.

Conclusions

It may be inferred that the trial drugTerminalia chebulaRetz. fruit powder mixed with vinegar is not inferior to terbinafine hydrochloride cream in the treatment of tinea corporis.
Investigation of dielectric, impedance, and magnetodielectric behavior in Bi5Ti3FeO15–Bi2Fe4O9 composites prepared by sol–gel modified method

Published: April 2023

We report detailed studies of the dielectric, impedance, and magnetodielectric properties of sol–gel synthesized (1−x)Bi5Ti3FeO15–(x)Bi2Fe4O9, x = 0.1 composites. The Rietveld refinement of X-ray diffraction data confirms the presence of mixed phases Bi5Ti3FeO15 (A21
am) and Bi2Fe4O9 (Pbam) with the orthorhombic crystal structure. The average grain size of the sample is calculated from scanning electron microscopy and found to be 0.74 µm and 0.80 µm for BTFO and BFO samples, respectively. The room temperature dielectric behavior of the prepared composite is demonstrated over a frequency range (102 Hz to 106 Hz) and at different fixed magnetic fields (0 T to 1.3 T). The decreasing trend of dielectric dispersion and loss signifies the presence of negative magnetodielectric and magneto-loss in the composite. Frequency-dependent magnetoresistance through impedance spectroscopy has been carried out to analyze the origin of the observed MD effect. The magnetic field-dependent MD and ML exhibit maximum coupling of about −0.19% and −0.36% at 50 kHz, respectively. The obtained MD response in this composite is due to the grain (capacitive) effect. These results establish a relation between the electric and magnetic order in the composites and extend their application in the field of magnetic memory and sensor devices.

Published: April 2023

We have successfully prepared a challenging and wonderful material, reduced graphene oxide (RGO)/graphene with improved quality from high pure graphite (HPG) efficiently by planetary ball milling process followed by arc plasma treatment under hydrogen atmosphere. Graphene oxides (GO) have been synthesized with varying degrees of oxidation via the planetary ball milling route by milling HPG between 3 – 8 h. The lowest C/O ratio (0.965) was observed for the 8 h ball milled sample. The as-prepared GOs were taken for only five min of arc plasma treatment under a hydrogen atmosphere. As the typical GO (prepared by 8 h ball milling) underwent a reduction by plasma treatment for producing a typical RGO sample, it was found that the C/O ratio increased from 0.965 in GO to 14.86 in RGO. RGO shows a hexagonal structure with well-defined crystallinity. Bi-layered and transparent types of structures were found in the RGO sample. The typical plasma treated RGO sample (prepared from 8 h ball milled GO sample) exhibits extraordinary BET surface area and electrical conductivity values of 1230.0 m2 g−1 and 4.587 × 103 S cm−1, respectively, compared to those of HPG.
“I would like to complain”: A study of the moves and strategies employed by Spanish EFL learners in formal complaint e-mails
Authors: Maíz-Arévalo Carmen , Méndez-García María-del-Carmen
Published: April 2023

Complaining constitutes a face-threatening and intricate speech act for native and non-native speakers of a language. Complaining implies reacting with discontentment to an act performed by the complainee, who is often urged to redress the predicament. In this context, pragmatic skills are vital because, unless endowed with an appropriate pragmatic repertoire and the corresponding language adequacy, speakers may jeopardize the communication process. Written complaints by non-native students have attracted scholarly attention in different contexts. However, written complaints by Spanish EFL students have been mostly neglected to date. Likewise, the influence of the writer’s gender on how complaints are performed has rendered some remarkable albeit scant studies. This study addresses the moves, strategies and substrategies deployed by Spanish EFL students in their emails of complaint, specifically looking into how the variable of gender influences their formulation of emails of complaint. For this purpose, emails of complaint of 90 L2 Spanish students with a certified C1 level were analyzed. Results show that students often transfer substrategies from their L1 and tend to delay the statement of the complaint in favor of lengthy openers, in contrast to native speakers. Furthermore, this preference for over-mitigation and over-politeness is especially employed by female students.

The main attention is paid to the analytical analysis of an oblique shock wave in a turbulent adiabatic gas flow. For this purpose, a modified Rankine–Hugoniot model was obtained. On its basis, a solution was derived for the Rankine–Hugoniot conditions for a gas flow with various degrees of turbulence, as well as the equation of the modified Hugoniot adiabat. The behavior of the velocity of an adiabatic turbulent gas flow during its passage through an oblique shock wave at different levels of turbulence is demonstrated. A modification of Prandtl’s law for the velocity coefficients was obtained. The shock polar was also analyzed. The relationship between the angular gas flow and the angle of the shock wave was derived. Finally, the condition for the appearance of an outgoing bow shock wave was obtained.
The relationship between required physician letters of recommendation and decreasing diversity in osteopathic medical school admissions

Published: April 2023

Context

Some racial and ethnic groups are underrepresented in the medical field because they face unique barriers to admission to medical school. One admission requirement that can present a barrier for applicants is the physician letter of recommendation (PLOR). Undergraduate students report confusion with the application process and lack of mentorship to be two of their biggest challenges to becoming a doctor. It is especially challenging to those who already have limited access to practicing physicians. Therefore, we hypothesized that in the presence of a PLOR requirement, the diversity of students who apply and matriculate into medical school will be decreased.

Objectives

This study aims to determine if a relationship exists between a PLOR requirement for the medical school application and the proportion of underrepresented in medicine (URM) students applying and matriculating to that school.

Methods

A retrospective study was conducted utilizing data published by the American Association of Colleges of Osteopathic Medicine Application Services (AACOMAS) on the race and ethnicity of applicants and matriculants to osteopathic medical schools during the years 2009–2019. In total, 35 osteopathic schools with 44 campuses were included in the study. Schools were grouped based on whether they required a PLOR. For each group of schools, descriptive statistics were performed for the following variables: number of total applicants, class size, application rate per ethnicity, matriculation rate per ethnicity, number of applicants per ethnicity, number of matriculants per ethnicity, and percentage of student body per ethnicity. The Wilcoxon rank-sum test was utilized to detect differences between the two groups. Statistical significance was assessed at the α=0.05 level.

Results

Schools that required a PLOR showed decreases in the number of applicants across all races and ethnicities. Black students showed the greatest difference between groups and were the only ethnicity to show significant reductions across all outcomes in the presence of a PLOR requirement. On average, schools that required a PLOR have 37.3% (185 vs. 295; p<0.0001) fewer Black applicants and 51.2% (4 vs. 8.2; p<0.0001) fewer Black matriculants.

Conclusions

This study strongly suggests a relationship between requiring a PLOR’s and decreasing racial and ethnic diversity in medical school matriculants, specifically the Black applicants. Based on this result, it is recommended that the requirement of a PLOR be discontinued for osteopathic medical schools.
Novalis und Nietzsche. Analogien und Differenzen zweier Dichter-Denker
Authors: Vietta Silvio
Published: April 2023

Novalis and Nietzsche: Analogies and Differences Between Two Poetic Thinkers.There are several substantial similarities between Novalis and Nietzsche. Stylistically, they both present their arguments and ideas in the form of short and concise prose (Aphorismus,Fragment), but there is also considerable overlap in terms of the general orientation of their thinking: both exhibit a certain concern for earthly nature and show an interest in the figure of the extraordinary individual, but they also have a common interest in physiology, in the idea of fiction, and in the night as a allowing for greater experiential depth. Moreover, Novalis and Nietzsche both warned of the rise of nationalism in Europe, to some extent anticipating a new form of war that eventually became a reality in the First World War. This essay, thus, seeks to outline a range of connections between early German romanticism and Nietzsche that would require further research.
