Exoplanet atmosphere studies are often enriched by synergies with brown dwarf
analogs. However, many key molecules commonly seen in brown dwarfs have yet to
be confirmed in exoplanet atmospheres. An important example is chromium hydride
(CrH), which is often used to probe atmospheric temperatures and classify brown
dwarfs into spectral types. Recently, tentative evidence for CrH was reported in
the low-resolution transmission spectrum of the hot Jupiter WASP-31b. Here, we
present high spectral resolution observations of WASP-31b’s transmission
spectrum from GRACES/Gemini North and UVES/Very Large Telescope. We detect CrH
at 5.6σ confidence, representing the first metal
hydride detection in an exoplanet atmosphere at high spectral resolution. Our
findings constitute a critical step in understanding the role of metal hydrides
in exoplanet atmospheres.

Published: August 2023

Comparative study of sensory structures on maxillary and labial palps in 71 species from 14 families by scanning electron microscopy and light microscopy revealed significant diversity of sensory structures. Seven principal types of sensory structures were found: pointed trichoid, blunt chaetoid, campaniform, thin basiconic, thick basiconic, petaloid, and pseudoplacoid sensilla. Pointed trichoid and blunt chaetoid sensilla occur on every palp segment. First and, especially, second segments of maxillary palps have bunches of very large blunt chaetoid sensilla on medial surfaces. Campaniform sensilla were found only on basal segments. Pseudoplacoid sensilla are common on the terminal segments of both labial and maxillary palps except for Ptilocolepidae and Hydroptilidae. The petaloid sensilla forming the sensory fields are found in groups surrounded by the soft cuticle, generally in depressions, on the apical segments either on maxillary and labial palps in Hydrobiosidae and Rhyacophilidae, only on labial palps in other studied Integripalpia, or on apical labial palp segment and third and fourth maxillary palp segments in Annulipalpia. The pointed tips of both maxillary and labial palps in lower families have apical sensory complexes looking like small conical outgrowths without microtrichia, each with one large thick basiconic sensilla on its tip and several shorter thick basiconic sensilla on lateral surfaces. We consider these seven types of sensilla along with the apical sensory complex and the assemblage of the petaloid sensilla as a part of Trichoptera ground plan. This primitive diversity changes in evolution so the apical sensory complex, the fields of petaloid sensilla, the groups of very long blunt trichoid sensilla of basal segments, and the pseudoplacoid sensilla disappear in some advanced instances, more often on the maxillary palps. Interspecific variations of sensilla might be important for species discrimination, while the distribution of certain sensory structures is important for higher taxonomy.

Published: August 2023

Background/Aims: While most cancer patients with end-of-life (EOL) care receive antibiotic treatments, antibiotic use should be decided appropriately considering the benefits, side effects, resistance, and cost effects. Antimicrobial stewardship programs (ASP) are important for patients with EOL care, but there is limited study analyzing actual antibiotic use in EOL care and the perceptions of Korean medical staff.Methods: Electronic medical records of 149 deceased cancer patients hospitalized in the medical hospitalist units at Asan Medical Center in Seoul from May 2019 to September 2021 were reviewed. Basic information, antibiotic use, duration, and changes were investigated. We surveyed medical staff’s perceptions of antibiotics in cancer patients with EOL.Results: Of the 149 cancer patients with EOL care, 146 (98.0%) agreed with physician orders for life-sustaining treatment (POLST). In total, 143 (95.9%) received antibiotics, 110 (76.9%) received combination antibiotic treatment, and 116 (81.1%) were given antibiotics until the day of death. In a survey of 60 medical staff, 42 (70.0%) did not know about ASP, and 24 (40.0%) thought ASP was important in EOL care. Nineteen doctors (31.7%) discussed the use or discontinuation of antibiotics with patients or caregivers when writing POLST, but only 8 patients (5.6%) stopped antibiotics after POLST.Conclusions: Most cancer patients with EOL care continue to receive antibiotics until just before their death. A careful approach is needed, considering the benefits and side effects of antibiotic use, and the patient’s right to self-decision. It is necessary to actively improve awareness of ASP and its importance for medical staff.
Factors influencing secondary school teachers' usage behavior of dynamic mathematics software: A partial least squares structural equation modeling (PLS-SEM) method
Authors: Yuan Zhiqiang , Deng Xi , Ding Tianzi , Liu Jing , Tan Qi
Published: August 2023

Dynamic mathematics software, such as GeoGebra, is a kind of subject-specific digital tool used for enabling users to create mathematical objects and operate them dynamically and interactively, which is very suitable for mathematics teaching and learning at all school levels, especially at the secondary school level. However, limited research has focused on how multiple influencing factors of secondary school teachers' usage behavior of dynamic mathematics software work together. Based on the unified theory of acceptance and use of technology (UTAUT) model, combined with the concept of self-efficacy, this study proposed a conceptual model used to analyze the factors influencing secondary school teachers' usage behavior of dynamic mathematics software. Valid questionnaire data were provided by 393 secondary school mathematics teachers in the Hunan province of China and analyzed using a partial least squares structural equation modeling (PLS-SEM) method. The results showed that social influence, performance expectancy and effort expectancy significantly and positively affected secondary school teachers' behavioral intentions of dynamic mathematics software, and social influence was the greatest influential factor. In the meantime, facilitating conditions, self-efficacy and behavioral intention had significant and positive effects on secondary school teachers' usage behavior of dynamic mathematics software, and facilitating conditions were the greatest influential factor. Results from the multi-group analysis indicated that gender and teaching experience did not have significant moderating effects on all relationships in the dynamic mathematics software usage conceptual model. However, major had a moderating effect on the relationship between self-efficacy and usage behavior, as well as the relationship between behavioral intention and usage behavior. In addition, training had a moderating effect on the relationship between social influence and behavioral intention. This study has made a significant contribution to the development of a conceptual model that could be used to explore how multiple factors affected secondary school teachers' usage behavior of dynamic mathematics software. It also benefits the government, schools and universities in enhancing teachers' digital teaching competencies.
A fully discrete local discontinuous Galerkin method based on generalized numerical fluxes to variable-order time-fractional reaction-diffusion problem with the Caputo fractional derivative
Authors: Liu Lijie , Wei Xiaojing , Wei Leilei
Published: August 2023

In this paper, an effective numerical method for solving the variable-order(VO) fractional reaction diffusion equation with the Caputo fractional derivative is constructed and analyzed. Based on the generalized alternating numerical flux, we get a fully discrete local discontinuous Galerkin scheme for the problem. From a practical standpoint, the generalized alternating numerical flux, which is distinct from the purely alternating numerical flux, has a more extensive scope. For $ 0 < \alpha(t) < 1 $, we prove that the method is unconditionally stable and the errors attain $ (k+1) $-th order of accuracy for piecewise $ P^k $ polynomials. Finally, some numerical experiments are performed to show the effectiveness and verify the accuracy of the method.
Differential sprouting ability during micropropagation of Nidularium minutum Mez (Bromeliaceae)
Authors: Teixeira Maria Gessi , Nievola Catarina  Carvalho
Published: August 2023

Nidularium minutum is an ornamental bromeliad from the Brazilian Rainforest. The micropropagation of this species is essential for obtaining plants available for conservation programs or commercial use. Our study aimed to establish an efficient plant production method by in vitro sprouting. This bromeliad takes a long time to sprout in vitro, and 10% of the plants produce shoots in a culture medium without plant growth regulators (PGRs). When subcultured in a PGR-free medium, these individualized shoots can sprout like the mother plant. The Murashige and Skoog basal medium (MS) containing 1.0 mg L-1 of 6-benzylaminopurine (BAP) promoted the induction of adventitious shoots in greater than 90% of the plants after 240 days of culture with an average of more than eight shoots per plant. Approximately 100% of the in vitro-produced shoots survived after acclimatization, reaching the flowering stage. Therefore, our results showed that in vitro regeneration of N. minutum depends on the cultivation period and that plants with a higher sprouting capacity can be selected and used as micropropagation matrices, contributing to the production of this endangered bromeliad.
Antibiofilm activity of bromelain from pineapple against Staphylococcus aureus
Authors: Silva Michelle Pereira , Calomino Mariana Alcântara , Teixeira Lenise Arneiro , Barros Rosana Rocha , Paula Geraldo Renato de , Teixeira Felipe Lopes
Published: August 2023

Bromelain is a set of proteolytic enzymes usually obtained from pineapple (Ananas comosus). Although bromelain has distinguished therapeutic properties, little is known about its proteolytic potential against opportunistic pathogens related to wound healing complications, such as Staphylococcus aureus. This study aimed to investigate the antibiofilm and antibacterial activity of bromelain in 43 clinical strains of S. aureus isolated from chronic wounds and blood cultures. Bromelain’s activity against S. aureus biofilm in vitro was assessed by analyzing biofilm formation in cultures grown in the presence of 1% bromelain and biofilm destruction after the addition of 1% bromelain to mature biofilms. Proteinase K and sodium metaperiodate were also added to mature biofilms in parallel to compare their activity with that of bromelain and, together with exopolysaccharide and protein production rate assays, to determine the chemical composition of the biofilm extracellular matrix of selected strains of S. aureus. Bromelain was also evaluated for its DNase activity and impact on cellular hydrophobicity and auto-aggregation. Mueller-Hinton agar dilution was used to determine bromelain minimal inhibitory concentration (MIC). Biofilm assays showed that 1% bromelain significantly inhibits S. aureus biofilm formation (p = 0.0157) by up to 4-fold and destroys its mature biofilms (p < 0.0001) by up to 6.4-fold, both compared to the control grown without bromelain. Biofilms of methicillin-resistant S. aureus strains isolated from chronic wounds were the most affected by bromelain treatment. No antibacterial activity was detected with bromelain MIC assays and the proteolytic activity of bromelain was identified as the main antibiofilm mechanism of the enzyme, though its DNase activity may also contribute. The epithelial therapeutic properties of bromelain combined with its antibiofilm activity against S. aureus make it a promising alternative to compose the therapeutic arsenal for the control of S. aureus biofilms in the context of wound care.

Published: August 2023

Background:

Polymorphous light eruption (PLE) is the most common idiopathic photodermatoses, with a wide range of clinical presentations that tends to mimic a number of dermatoses.

Objective:

The aim was to study the clinicopathological profile in patients diagnosed with PLE.

Materials and Methods:

This was a cross-sectional, descriptive study of seventy clinically diagnosed cases of PLE over a period of 1 year, wherein following patient enrolment, they underwent a thorough clinical evaluation, followed by a skin biopsy that was studied categorically.

Results:

A male preponderance (62.8%) was observed. Majority of patients were in the 21-30 years’ age group (28.6%). Pruritus was witnessed in 98.5% of patients. The most common morphological type encountered was plaque PLE (35.7%), followed by lichen nitidus type (11.4%). Commonest site of involvement was sides and back of neck (75.7%), followed by dorsolateral aspect of both arms (31.4%). Hyperkeratosis was identified in 82.8%, spongiosis in 87.1%, liquefactive degeneration of basal cell layer in 82.8%, atrophy in 24.2%, and moderate-to-severe lymphocytic dermal infiltrates in 90% of our cohorts.

Conclusion:

PLE is a disorder with diverse clinical presentations, manifesting usually in the third decade of life that closely mimics a variety of other cutaneous disorders. Histological examination with certain specific criteria enables the clinician to arrive at a concrete conclusion in those cases where clinical findings alone pose diagnostic difficulties.
Comparison of Clinical Efficacy and Trichoscopic Changes in Alopecia Areata of the Scalp following Treatment with Intralesional Triamcinolone Acetonide and Autologous Platelet-Rich Plasma
Authors: Albadri Warood , Inamadar Arun C
Published: August 2023

Background:

Alopecia areata (AA) is an autoimmune disease affecting the scalp and body, resulting in hair loss. The fundamental goal of management is to keep the pathology under control. Intralesional corticosteroids suppress T-cell-mediated attacks on hair follicles. Platelet-rich plasma (PRP) contains growth factors that stimulate hair follicle stem cells and have anti-inflammatory properties with fewer side effects. Trichoscopy shows exclamation hair and black dots in the acute stage, yellow dots in long-standing cases, and short vellus hair in regrowing patches.

Objective:

The aim of this study was to evaluate and compare the efficacy of intralesional triamcinolone acetonide with autologous PRP in the treatment of two different scalp AA patches in the same individual.

Materials and Methods:

This was a hospital-based prospective follow-up study. Patients with two different patches of alopecia were selected. One was treated with intralesional triamcinolone acetonide (10 mg/ml) and the other with PRP given at 3-week intervals for four treatment sessions. Comparison of results was based on MacDonald Hull and Norris grading system and trichoscopy.

Results:

Out of 32 patients, 8 (25%) in triamcinolone-treated patches and 3 (9.4%) in PRP-treated patches showed complete hair regrowth at 12 weeks. Furthermore, a faster response was seen with triamcinolone. On trichoscopy, both patches showed an increase in short vellus and terminal hair and a reduction in yellow dots and exclamation hair. No changes in black dots were seen.

Conclusion:

Intralesional triamcinolone acetonide is more effective than PRP in the treatment of AA of the scalp and is safe. Trichoscopic findings indicate response to treatment and reduction of disease activity.

Authors: Sharma Geeta , Sharma Shilpi
Published: August 2023

Background:

Skin warts are benign tumors caused by infection of keratinocytes with human papillomavirus (HPV), visible as well-defined hyperkeratotic protrusions. Recently, immunotherapy is emerging as a new modality in the treatment of viral warts. Immunotherapy using Vitamin D3 is being tried widely for the treatment of warts. It is based on enhancing the immune system to achieve an HPV-targeted immune reaction.

Objective:

The objective of this study was to evaluate the safety and efficacy of intralesional Vitamin D3 for the treatment of viral warts.

Materials and Methods:

This was a hospital-based longitudinal study of 55 patients with viral warts. 0.5 ml Vitamin D3 solution (600,000 IU, 15 mg/ml) was injected in the base of the wart. A maximum of four warts per session were injected at 2-week intervals until resolution or for a maximum of four treatment sessions. The clinical assessment was done by pre- and posttreatment photographic comparison at baseline, before each treatment session, and after the completion of treatment.

Results:

Thirty-five patients (63.63%) showed complete clearance, 15 patients (27.27%) showed partial clearance, and 5 patients (9.09%) patients showed no improvement. No significant side effects were observed except for pain and mild swelling at the site of injection.

Conclusion:

Authors: Kapoor Asmita , Pol Devayani , Kumar Ajay , Deora Mahendra Singh
Published: August 2023

Enoxaparin is a low-molecular-weight heparin (LMWH), i.e., widely used for prophylaxis and therapy of venous thromboembolism. Skin necrosis after subcutaneous injection is an uncommon and possibly underreported complication of LMWH. We report a case of enoxaparin-induced localized skin necrosis. Prompt diagnosis, discontinuation of LMWH, and work-up to rule out heparin-induced thrombocytopenia, a potentially life-threatening condition goes a long way in improving the outcome.

Pentazocine Dependence in a Female Patient with Tubercular Meningitis: A Case Report that Calls for Treatment Gap Reduction through Multilevel Screening
Authors: Kaur Harneet , Singh Hershdeep
Published: August 2023

Pentazocine abuse is relatively uncommon and even rarely seen in Indian females. It is often associated with multiple dermatological sequelae due to the repetitive local trauma at the injection site and the local effects of the drug. While managing opioid dependence, pathways of care vary a lot, thus deeming the multilevel screening at the level of general practitioners, pharmacists, mental health professionals, and other specialties, rather crucial. This one step can lead to a significant reduction in the treatment gap of opioid dependence. Here, we present a case of a female who started self-injecting a combination of pentazocine and promethazine (Phenergan) posttubercular meningitis recovery for her persistent postmeningitic headache.
Implication of age-related changes on anesthesia management
Authors: Luca Ersilia , Schipa Chiara , Cambise Chiara , Sollazzi Liliana , Aceto Paola
Published: August 2023

Elderly patients have a high risk of perioperative morbidity and mortality. Pluri-morbidities, polypharmacy, and functional dependence may have a great impact on intraoperative management and request specific cautions. In addition to surgical stress, several perioperative noxious stimuli such as fasting, blood loss, postoperative pain, nausea and vomiting, drug adverse reactions, and immobility may trigger a derangement leading to perioperative complications. Older patients have a high risk of major hemodynamic derangement due to aging of the cardiovascular system and associated comorbidities. The hemodynamic monitoring as well as fluid therapy should be the most accurate as possible. Aging is accompanied by decreased renal function, which is related to a reduction in renal blood flow, renal mass, and the number and size of functioning nephrons. Drugs eliminated predominantly by the renal route need dosage adjustments based on residual renal function. Liver mass, hepatic blood flow, and intrinsic metabolic activity are decreased in the elderly, and all drugs metabolized by the liver have a variable half-life, thus requiring dose reduction. Decreased neural plasticity contributes to a high risk for postoperative delirium. Monitoring of anesthesia depth should be mandatory to avoid overdosage of hypnotic drugs. Prevention of postoperative pulmonary complications requires both protective ventilation strategies and adequate recovery of neuromuscular function at the end of surgery. Avoidance of hypothermia cannot be missed. The aim of this review is to describe comprehensive strategies for intraoperative management plans tailored to meet the unique needs of elderly surgical patients, thus improving outcomes in this vulnerable population.
Advancing Robot Perception in Non-Spiral Environments through Camera-based Image Processing
Authors: Hoorfar Hamid , Bagheri Alireza
Published: August 2023

Robot perception heavily relies on camera-based visual input for navigating and interacting in its environment. As robots become integral parts of various applications, the need to efficiently compute their visibility regions in complex environments has grown. The key challenge addressed in this paper is to devise an innovative solution that not only accurately computes the visibility region V of a robot operating in a polynomial environment but also optimizes memory utilization to ensure real-time performance and scalability.The main objective of this research is to propose an algorithm that achieves optimal-time complexity and significantly reduces memory requirements for visibility region computation. By focusing on sub-linear memory utilization, we aim to enhance the robot's ability to perceive its surroundings effectively and efficiently.Previous approaches have provided solutions for visibility region computation in non-spiral environments, but most were not tailored to memory limitations. In contrast, the proposed algorithm is designed to achieve optimal time complexity that is O(n) while reducing memory usage to O(c/log n) variables, where c < n represents the number of critical corners in the environment. Leveraging the constant-memory model and memory-constrained algorithm, we aim to strike a balance between computational efficiency and memory usage.The algorithm's performance is rigorously evaluated through extensive simulations and practical experiments. The results demonstrate its linear-time complexity and substantial reduction in memory usage without compromising the accuracy of the visibility region computation. By efficiently handling memory constraints, the robot gains a cost-effective and reliable perception mechanism, making it well-suited for a wide range of real-world applications.The constant-memory model and memory-constrained algorithm presented in this paper offer a significant advancement in robot perception capabilities. By optimizing the visibility region computation in polynomial environments, our approach contributes to the efficient operation of robots, enhancing their performance and applicability in complex real-world scenarios. The results of this research hold promising potential for future developments in robotics, computer vision, and related fields.

Cephalocaudal-Remote Approach
Authors:   , Ledesma David
Published: August 2023

This opinion paper introduces a global, top-down, bottom-up, and lateral perspective on occupation, known as the Ledesma Cephalocaudal-Remote Approach, which can be used to build an integrated, holistic occupational therapy practice. This approach combines the Ayres (1960, 1966, 1972, 1979) cephalocaudal and vestibular sensory-motor development (confirmed by Lane et al., 2019); the Wilke et al. (2017) remote interoceptive, proprioceptive, and nociceptive stretching, based on Myers (2017) myofascial chain approach; the Serino (2019) peripersonal and multisensory-motor approach; the Leisman et al. (2016) bidirectional dynamic influence of motor activity and cognition approaches, and the Sadil (2019) evidence for rapidly learned low-level associations without top-down knowledge approach. The Ledesma Cephalocaudal-Remote Approach leads both practitioner and client through conscious sensory-motor experiences that develop and maintain a healthy functional self-relationship. Engaging in whole human organism range of motion/position activity develops the physical health of embodied occupational capabilities. Examples include lying down, crawling, kneeling, sitting, standing, and walking. Therapeutic use of self is employed consciously as an interpersonal tool by the occupational therapist to experience whole human organism range of motion/position activity. Once the therapist develops proficiency, they then employ therapeutic use of self again to mentor the client. This practitioner mode redefines the role of the occupational therapist from facilitator to mentor, which is a significant contribution to the existing “modes of practice” in the intentional relationship model (Taylor, 2008). A description of experiencing and teaching the first (physical) phase of practice, known as “Beginner Phase,” is provided to illustrate application of the model in occupational therapy practice

Published: August 2023

O sono dos adolescentes tem características próprias e é influenciado pelos hábitos da sociedade moderna, que frequentemente perturbam um ritmo saudável de sono e vigília. A presente investigação avaliou a qualidade de sono de alunos do ensino secundário do concelho de Bragança e a sua relação com o consumo de substâncias psicoativas, estudando-se uma amostra de 345 alunos. Os dados foram recolhidos em maio de 2017, através de um questionário que incluía o Índice de Qualidade do sono de Pittsburgh (IQSP) e questões sobre o consumo de substâncias psicoativas. Constatou-se que a maioria dos adolescentes em estudo consome bebidas alcoólicas (73.6%), café (66.4%) e outras bebidas com cafeína ou derivados (87.8%) e que 10.4% são fumadores. Concluiu[1]se que o risco de má qualidade do sono é superior nos adolescentes fumadores, que consomem bebidas alcoólicas e que consomem diariamente bebidas com cafeína ou derivados. Verificou-se ainda que a qualidade do sono também se relaciona com o consumo de tabaco e bebidas com cafeína e derivados nas três horas antes de dormir, sendo o risco de má qualidade de sono superior nos adolescentes que frequentemente consomem bebidas com cafeína e nos que frequentemente fumam nesse período específico. As relações verificadas remetem-nos para a importância de intervir na educação e promoção da qualidade de sono dos adolescentes, associando o estilo de vida e o consumo de substâncias psicoativas. Este estudo pode ser uma importante ferramenta para educadores, decisores políticos e comunitários, no sentido de definirem planos de intervenção concretos em contexto escolar na área do sono, consumo de substâncias psicoativas, e no estabelecimento de rotinas promotoras da saúde.

Published: August 2023

Neste trabalho, mostram-se os resultados de uma experiência em neurociência sobre a curta metragem “Memorias de un cine de provincias”, na qual a atividade electro dérmica foi medida simultaneamente num grupo de 32 pessoas pela tecnologia Sociografica. Os resultados mostram uma acentuada curva de atenção ao longo da projeção, numa situação de atenção por expectativa. O mais intenso dos picos emocionais foi registado nos momentos prévios a um desenlace, esperado ou não. Essa emoção foi verbalizada em termos positivos de alegria e felicidade na pesquisa realizada no final da transmissão.
A influência da gestão publico-privada no setor das águas em Portugal
Authors: Costa Nuno , Valente Maria
Published: August 2023

O setor das Águas em Portugal tem vivido momentos de mudança em função da agenda política, nele coexistindo entidades gestoras privadas ao lado das entidades gestoras tradicionais (públicas). Tal circunstância per se justificaria um estudo sobre a influência da gestão pública ou privada na universalidade de acesso, na garantia da qualidade do serviço e na acessibilidade de preço do bem água, é, no entanto, a publicação do primeiro Relatório Anual dos Serviços de Águas e Resíduos (RASARP), em 2013, que impulsiona esse estudo. A informação aí divulgada referente às 384 entidades a operar no setor, permite a construção de uma base de dados capaz de suportar um modelo empírico ajustado à especificidade das variáveis em análise. A partir da sua estimação o estudo infere que as entidades de gestão (EG) de natureza não empresarial permitem uma melhor garantia da acessibilidade/universalidade do serviço água, ainda que revelem menor eficácia face aos gastos incorridos na obtenção de cada unidade produzida. A validação (ou não) destas conclusões exige a construção de uma base de dados painel, tarefa possibilitada pelos relatórios RASARP subsequentes.
Uso de produtos naturais com fins terapêuticos em pediatria
Authors: Nascimento Luís , Pimentel Maria , Aragão Maria
Published: August 2023

A literatura tem demonstrado que, no tratamento de doenças infantis, o uso de produtos naturais é particularmente adequado. Entendemos útil dispor de agentes terapêuticos cuja via de metabolização seja mais conhecida. O amplo índice terapêutico de muitos fitoterápicos e a sua tolerância criam boas perspetivas para a infância. Sendo considerada uma terapêutica segura, têm sido relatados efeitos adversos e interações decorrentes da administração simultânea de preparações à base de plantas e medicamentos convencionais (Izzo, 2005; Cunha, Ribeiro & Roque, 2009). O presente estudo tem como objetivos conhecer a utilização de produtos naturais com fins terapêuticos em crianças e jovens, inscritos na consulta de pediatria da Unidade Local de Saúde do Nordeste (ULSN), e verificar se o recurso a esses produtos se deve ao aconselhamento de um profissional de saúde ou ao conhecimento empírico. Foram inquiridos todos os pais que acompanhavam os filhos na 1ª consulta da especialidade, entre março e agosto de 2013, utilizando como instrumento de recolha de dados um questionário, elaborado par o efeito. Verificou-se que o uso de fitoterapia e de produtos naturais em pediatria não é muito frequente nos inquiridos em estudo. Nos casos em que ocorreu, a sua utilização fez-se por livre iniciativa e conhecimento empírico e, nem sempre, com indicações terapêuticas adequadas. Concluiu[1]se pela necessidade de mais informação sobre esta temática, de forma a contribuir para uma mais efetiva, correta e responsável utilização destes produtos.
Governo das sociedades nas empresas familiares e não familiares: evidência para Portugal
Authors: Lisboa Inês
Published: August 2023

As empresas familiares apresentam características únicas que podem causar impacto no governo das sociedades. Este trabalho tem um duplo objetivo. Primeiro são comparados os modelos de governo de sociedades das empresas familiares e não familiares. Em segundo lugar estas empresas são analisadas em maior detalhe, discriminando entre empresas cotadas no PSI 20 (o índice de mercado português) e as restantes. A amostra inclui 37 empresas, 16 das quais do PSI 20. Utilizando uma análise quantitativa, os resultados mostram que as empresas familiares, especialmente as do PSI 20, apresentam mais membros independentes, cumprem mais recomendações de governo de sociedades e exibem mais informações sobre os modelos de governação nas suas páginas web do que outras empresas. Isso sugere que as empresas familiares tentam evitar as assimetrias de informação para precaver-se de erros de valorização, manter sua continuidade e reduzir os custos da agência.

Published: August 2023

Os hábitos alimentares possuem um papel fundamental na vida de um ser humano. O Instituto Politécnico da Guarda (IPG) possui um total de 2692 estudantes, que todos os dias fazem escolhas alimentares. Dada a sua importância, este estudo tem por objetivo avaliar: a) as escolhas preferências/seleções alimentares dos estudantes; b) o local do seu consumo e c) a sua composição corporal. Para tal, recorreu-se à realização de um inquérito por questionário, denominado “Hábitos Alimentares da Comunidade IPG”, dirigido a todos os estudantes das quatro unidades orgânicas4 Responderam ao questionário cerca de 14% dos estudantes do IPG. Após a análise dos resultados, conclui-se que seria importante sensibilizar os estudantes para a prática de uma alimentação saudável para tal deveriam ser realizadas várias ações de formação nas respetivas escolas, rastreios e até mesmo algumas competições de forma a que as boas escolhas alimentares se realizem de forma motivada e não obrigatória. Como os estudantes dão muita importância às cantinas, esta poderia ser um veículo importante para promover os bons hábitos alimentares.
Uncovering University Teachers' Perspectives: Conceptualizations, Factors, and Perceptions of Second Language Learner Engagement
Authors: Alzaanin Eman
Published: August 2023

Second language (L2) learner engagement has been a key theme in applied linguistics over the past two decades; however, teachers' voices have been largely absent from L2 learner engagement research. In addition, little is known about what learner engagement means to L2 language teachers. Through semi-structured, in-depth interviews, this study aims to capture the conceptualizations of learner engagement and the perceptions of the factors facilitating or hindering learner engagement in L2 learning in a Saudi university context, as expressed by 12 English as a Foreign Language university (EFL) teachers. The data analysis method used was inductive thematic analysis. The findings revealed that, for the participating teachers, learner engagement is a multifaceted concept, although it was commonly seen in terms of the behavioral and affective dimensions. Teachers' perceptions of the factors that facilitate or hinder the promotion of learner engagement were also explored, and among these, the most salient factors were learners' attributes and behaviors, teachers' pedagogical practices, student-teacher rapport, social context, institutional policies, and broader educational system. This study underscores the urgent need to acknowledge the importance of L2 teachers' perceptions of learner engagement within and beyond the EFL classroom. It emphasizes the crucial role of continuous professional development in empowering teachers to enhance their skills in engaging learners and effectively addressing the challenges they face.

This study aims to determine usury that occurs in credit transactions. This study uses a qualitative method by taking a library approach, internet searches which are generally carried out indirectly do not jump directly into the field in searching for data sources . Credit is the provision of money made between two parties, usually between a bank and another party that has previously obtained the agreement of both parties where the person who borrows has the right and must repay the loan in accordance with the time and agreement that has been made. Riba is "additional" meaning when we make a loan to one party, for example a bank, there will be additional money when we return the money, it is different from the principal money we borrow, this is called usury. As we know when we make a loan at a bank, we will not be separated from what is called interest. This interest that we usually know in Islam is usury, something that is prohibited in Islam.
