IMPACT OF MUSCLE STRENGTHENING ON JOINT STRENGTH IN TAE KWON DO ATHLETES
Authors: Qiu Wei
Published: February 2023

ABSTRACT Introduction: Taekwondo athletes' knee flexor and extensor muscle groups reveal the joint's biomechanical characteristics when tested and may suggest a direction for individual strength training in Tae Kwon Do athletes. Objective: Evaluate the impact of muscle strengthening on joint strength in Tae Kwon Do athletes. Methods: The study was conducted through a literature review, experimental test, and logical analysis. Results: The strength of the flexion muscle group in Taekwondo athletes was significantly higher than that of extension. The flexion-extension ratio is high. This characteristic may be related to the athletes' habit of supporting body weight with the left leg and attacking with the right leg. Conclusion: Strength training of the knee flexors is indicated for Tae Kwon Do athletes, balancing the muscular balance by raising the flexor fatigue index close to that of the extensors, improving the strength and endurance of the knee flexor muscles. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
EFFECTS OF STRETCHING ON LOWER LIMB STRENGTH IN BASKETBALL ATHLETES
Authors: Chen Jie
Published: February 2023

ABSTRACT Introduction: Basketball players depend on excellent explosive power in the lower limbs for training and competition activities such as starting, braking, accelerating, decelerating, running, and jumping instantly and quickly. The level of Chinese athletes in this aspect is lower than world powers, and formulating training focused on explosive strength can enhance the training of these athletes. Objective: Study the effects of stretching on lower limb strength in basketball athletes. Methods: 20 young male basketball players selected as volunteers for the research were randomly divided into an experimental and control group, with 10 people in each group for retrospective analysis. The effect of rapid stretching compound training on the explosive power of lower limbs in basketball players was evaluated using the comparative method of literature data, expert interviews, experimental methods, and mathematical statistics. Results: After 8 weeks of training, the scores of each test index in the control group were significantly improved, including the standing jump and long-distance scores (P < 0.01). Unipodal takeoff and post-run long-range scores were significantly improved (P < 0.05). Conclusion: Both traditional resistance and compound lower limb stretching training can improve explosive power in young basketball players, but compound training showed more prominent results. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Abstract The effects of onion and its by-products on metabolic changes induced by excessive consumption of a high fat diet have been the focus of many studies. The aim of this study was to systematically review the effects of onion and its by-products antioxidant, anti-inflammatory and anti-obesity in rats exposed to a high-fat diet. Five databases were used: Pubmed, EMBASE, Science Direct, Web of science and Scopus until June 2020 updated December 1, 2022. Research of the articles was carried out by two reviewers, searching and selecting studies after an initial reading of the titles and abstracts. In total, 2,448 papers were found and, after assessing against the inclusion and exclusion criteria, 18 papers were selected for this review. The findings of this review show the beneficial effects of onion and its by-products on inflammatory parameters, obesity, cardiovascular disease, thermogenesis and hepatic alterations generally associated with the consumption of a high-fat diet.
The WCAA Global Survey of Anthropological Practice (2014-2018): Reported Findings
Authors: McGrath Pam , Acciaioli Greg , Millard Adele , Metzner Emily , Nešković Vesna Vučinić , Mathur Chandana
Published: February 2023

Abstract The Global Survey of Anthropological Practice (GSAP), the first of its kind, was undertaken by the World Council of Anthropological Associations (WCAA) to provide insights about anthropology as a transnational profession, the ongoing relevance of the discipline in addressing global problems, issues in employment and gender equity, and the range of anthropological practice and expertise. Respondents to the survey were living in 113 different countries. This article summarizes some of the GSAP’s most general global findings. The GSAP data suggest that within the discipline of anthropology, woman-identified practitioners predominate, except in archaeology and linguistics; yet, women were more likely to report being under-employed and/or not fairly compensated for their work. Universities were the largest employers of anthropologists, but public policy work and public engagement featured centrally in many respondents’ work. The social and cultural anthropology subdisciplines appear to be the most widely practiced the world over, but many respondents also engaged in applied anthropology. However, social media platforms, which might allow anthropologists to reach broader publics, were under-utilized by respondents, who were more likely to publish in closed, internal, and disciplinary specific forums. The GSAP illustrated the global mobility of respondents, including for higher education (and the data on this reflected the hegemony of North Atlantic centers of higher education); yet, many anthropologists around the world have expertise and undertake research in their home countries. Finally, the GSAP found that respondents published their work predominantly in English, although not exclusively, and documented a diversity of languages in which anthropologists publish.
Reports of a struggle: Prison, gender, and activism in an association of prisoners’ relatives
Authors: Lago Natália
Published: February 2023

Abstract The article explores the connections between gender, prison, and activism in AMPARAR, an association that works with prisoners’ families in São Paulo, Brazil. The ethnography is developed in the activities of the association and in the monitoring of the connections mobilised by these activities. AMPARAR’s work is located in an institutional web that includes non-governmental organisations and public institutions that produce both a violating state and a state that claims rights and guarantees. AMPARAR and the family members articulated by the association put a human face and body to complaints, and identify violence and humiliation perpetrated not only on their bodies, but on their husbands and children deprived of their freedom. Gender and sexuality are languages that allow such evocation and contribute to women producing a place of mediators and rapporteurs for the abuses that occur within prisons.

Published: February 2023

Resumo O trabalho avaliou o comportamento de bezerras leiteiras, criadas em bezerreiros de modelo tropical, contendo diferentes geossintéticos como material de cobertura. Foram avaliadas 20 fêmeas Girolando, Jersey e Holandesa com peso inicial médio de 40,6 Kg durante a fase de aleitamento. O delineamento experimental foi de blocos casualizados completos, em arranjo fatorial 4 x 3 com 5 repetições. Os materiais de cobertura foram: malha de polietileno, geocomposto drenante, geotêxtil não-tecido e geotêxtil tecido foram o primeiro fator e os períodos do dia (08 às 11, 11:15 às 14 e 14:15 às 18 horas) foram o segundo fator. Foram avaliadas as variáveis ambientais e calculados os índices de conforto térmico: índice de temperatura do globo negro e umidade e índice de temperatura equivalente. As médias do índice de temperatura do globo negro e índice de temperatura equivalente foram 79 e 26, respectivamente. O comportamento andando diferiu entre tratamentos (P<0,05), sendo mais frequente no tratamento geotêxtil tecido. A frequência comportamental mais observada ao longo do dia foi deitada à sombra (53%) deixando evidente a importância da disponibilização de sombreamento artificial para essa fase de vida. Os materiais de cobertura geossintéticos Geodrenante e Geotêxtil não-tecido, comparados à malha de polietileno, foram os mais apropriados para a utilização como sombreamento em regiões de clima tropical para bezerras em fase de aleitamento.

Published: February 2023

Resumo Os répteis têm um papel fundamental para a compreensão da independência reprodutiva da água que surgiu nos amniotas. Várias adaptações ocorreram, inclusive em padrões e comportamentos locomotores, e o sistema nervoso se adaptou a esses novos hábitos. Descrevemos a anatomia macroscópica e a citoarquitetura do encéfalo do calango (Tropidurus torquatus), um lagarto abundante na América do Sul. Quinze espécimes foram capturados, eutanasiados e seus encéfalos dissecados, oito destes foram processados e corados em hematoxilina-eosina. As principais áreas do cérebro são o telencéfalo e o diencéfalo, na parte anterior do encéfalo, teto e tegmento, no mesencéfalo e bulbo e cerebelo, na parte posterior do encéfalo. Os bulbos olfatórios principais e acessórios são as estruturas mais rostrais do cérebro e são compostos por seis camadas. Os hemisférios cerebrais compõem o telencéfalo e são divididos em pálio e subpálio. Os córtices medial, dorsomedial, lateral e dorsal fazem parte do pálio. Estriado, pálido e septo compõem o subpálio. O diencéfalo é composto pelo tálamo, epitálamo e hipotálamo. O mesencéfalo possui um tegmento ventral, composto de torus semicircularis e um tecto óptico dorsal com 14 camadas. A maior parte da parte posterior do encéfalo é composta pelo bulbo, e o cerebelo surge como uma projeção dessa estrutura, em formato plano, com três camadas. Em geral, o encéfalo de Tropidurus torquatus se assemelha ao de outros lagartos, com suas próprias adaptações.
Eustrongylides spp. (Nematoda: Eustrongylidae) em Polypterus endlicheri na região central do Rio Grande do Sul, Brasil
Authors: Lignon Julia Somavilla , Stainki Théo Monteiro , Monteiro Silvia Gonzalez
Published: February 2023

Resumo A criação de peixes para ornamentação teve sua demanda aumentada nos últimos anos no Brasil, no entanto, o ambiente aquático dos criatórios artificiais facilita a invasão por agentes patogênicos, incluindo zoonoses parasitárias, que são um fator limitante para produção causando perdas econômicas nas criações. O conhecimento da distribuição de agentes causadores de enfermidades parasitárias é importante para que se possa intervir nos criatórios, portanto, o objetivo do presente trabalho é relatar a ocorrência da infecção por larva de Eustrongylides sp. (Nematoda: Eustrongylidae) em Polypterus endlicherii (Polypteriformes: Polypteridae) na região central do Rio Grande do Sul, Brasil. O nematódeo foi identificado após ser liberado de um cisto nas escamas, de um peixe da espécie P. endlicherii. Pode-se concluir que este é o primeiro registro da ocorrência de larvas de Eustrongylides sp. em peixes no Rio Grande do Sul, evidenciando que o parasito está presente na região central do estado. Portanto, mais estudos devem ser realizados a fim de verificar a presença dos parasitos em peixes destinados ao consumo humano. Salienta-se ainda, a necessidade de se ter maior cuidado ao alimentar peixes com oligoquetas, principalmente os destinados para alimentação humana.
REALOCAÇÃO SETORIAL DA OCUPAÇÃO E SEUS EFEITOS SOBRE O CRESCIMENTO DA INFORMALIDADE NO BRASIL NO PERÍODO 2015-2018
Authors: Catelan Davi Winder , Cunha Marina Silva da
Published: February 2023

RESUMO O objetivo deste estudo é analisar a relação entre as mudanças na composição setorial da ocupação e o crescimento da informalidade ocorridos no Brasil no período 2015-2018, utilizando os microdados da Pesquisa Nacional por Amostra de Domicílios (Pnad) Contínua. Os resultados sugerem que a realocação ocupacional, ocorrida nos setores de atividade, exerceu impacto negativo sobre o aumento da informalidade no Brasil, nas Unidades da Federação e para os grupos de trabalhadores considerados, enquanto a realocação ocorrida nas categorias de trabalho exerceu impacto positivo. A contribuição negativa foi atribuída às perdas de participação da construção civil e da agricultura na ocupação total e ao ganho dos serviços, devido ao maior grau de informalidade nos dois primeiros setores. A contribuição positiva nas categorias de trabalho está relacionada à perda de participação do trabalho assalariado e ao decorrente aumento do trabalho por conta própria, pois a informalidade nesse último foi maior.

Resumo Contra a vertente teórica das materialidades da comunicação, que se baseia no conceito de presença e na fisicalidade do suporte, este artigo pretende repensar o campo das materialidades propondo a passagem de uma lógica da presença para uma lógica da relação. Assim, trata-se de sugerir uma teoria da materialidade relacional. As implicações de tal possibilidade permitem não apenas uma crítica ao conceito de presença, mas também uma revisão da própria noção de intermidialidade. Para esse propósito, os aportes teóricos utilizados foram Marshall McLuhan, Richard Grusin, Jay Bolter e Gilles Deleuze.
Epistemological Reflections and Doing Science in Contemporary Administration
Authors: Andion Carolina
Published: February 2023

ABSTRACT RAC has prioritized studies that advance the scientific debate in the field of contemporary administration, favoring original and interdisciplinary studies with epistemological approaches expanding conceptual boundaries and innovatively connecting theory and practice. RAC values responsible knowledge production that contributes in and out of academia. Given this, it is vital to reinforce a research agenda for administration, broadening the horizons of epistemological and metatheoretical discussions on the content of the knowledge produced and on how this knowledge is produced. Such a research agenda must focus on the field’s scientific practices, the scope and limits, and the consequences of these practices in academia and beyond. This editorial presents some reflections and contributions to thinking about new epistemological paths and supporting the use of new praxeological avenues in the field. The intention is to help consolidate a research agenda on epistemology and practices in the scientific work of administration oriented toward the most prominent societal challenges.

Published: February 2023

ABSTRACT Sugarcane seedling quality is strongly influenced by the substrate used. Currently, alternative substrate sources from the sugarcane industry itself have been used; however, there is no specific substrate to produce pre-sprouted seedlings. This study aimed to evaluate the quality of pre-sprouted sugarcane using substrates with different proportions of carnauba bagana (0, 20, 40, 60, 80 and 100 %) plus soil. The experimental design was completely randomized, with six treatments and five replicates. Pre-sprouted seedlings cultivated using substrate composed by 80 % of carnauba bagana showed the best response for number of leaves, diameter, shoot length, shoot, root and total dry mass, and Dickson Quality Index, owing to the improvement in the substrate physical and chemical characteristics.

Induction of mutagenesis on Chrysanthemums
Authors: Haspolat Gulden
Published: February 2023

Abstract Crop genetic diversity has a significant role in improving new plants through breeding. The chrysanthemum contains the most mutant varieties, making mutation breeding one of the most widely utilized breeding procedures for ornamental plants. The goal of this research is to use gamma irradiation to induce genetic variation and mutation breeding to improve chrysanthemum features. In vitro bud explants of the white ‘Bacardi’ type were treated with gamma rays at 20 Gy on this scope. The explants were subcultured until M1V4 growing period occurred, and observations were made during blooming on this time. Variable flower head widths, distinction on plant heights and widths, numerous flower numbers, color and size variations of ray florets were among the mutagenic changes observed in plants and flowers. Ray florets varied in length, width, number of rows, and color. The mutation frequency of the population was estimated 1.1% and yellow-colored florets were developed whereas the control group remained white. The dendrogram was grouped into five groups with 1, 28, 31, and 41 mutants in each based on the plant height and width, plant stem height and width, number of shoots and flowers per plant, flower head width, ray florets’ number- height- color, number of leaves, leaf length and width, and weight of flowering stems. The yellow-colored mutants were located in the first, second, and fourth groups. The advantageous mutations could result in improving new varieties. Gamma radiation is an effective mutagen for creating new chrysanthemum types when applied to in vitro bud explants.

Resumo Introdução Existem profundas relações entre as festas Brega e a cidade de Belém do Pará, Brasil, manifestadas em práticas cotidianas que influenciam as características culturais, performáticas e identitárias da cidade. Essas festas são realizadas semanalmente e informam três atores principais: festeiros, bregueiros e DJs. Mesmo amplamente validadas na periferia, as festas Brega enfrentam processos de marginalização social de suas práticas, sendo atribuídas noções depreciativas aos modos de viver e às ações cotidianas dos sujeitos envolvidos com esse movimento. Dentre as festas de Brega, destacamos nesse trabalho o Baile da Saudade, o qual concentra características mais ligadas ao movimento inicial do Brega em Belém. Objetivo Identificar os significados de ocupar-se das/nas festas de Baile da Saudade com base na perspectiva dos principais atores. Método A pesquisa, de natureza qualitativa e inspirada por abordagem etnográfica, ouviu cinco participantes: um DJ, dois festeiros e dois bregueiros. Os dados foram gerados através de observação participante, entrevistas semiestruturadas e por meio de Photovoice. Os recursos foram analisados por meio de Análise Temática. Resultados Foram geradas quatro unidades temáticas que informam as particularidades do Baile da Saudade, a construção da festa enquanto produto cultural, as diferenciações de consumo entre o Centro e a Periferia da cidade, bem como estigmas e aceitações associados ao Baile. Conclusão O estudo revelou os condicionantes, as tensões e os potenciais de ocupar-se das/nas festas de Baile da Saudade, bem como permitiu refletir sobre algumas ocupações humanas a partir de perspectiva contra hegemônica.

ABSTRACT The quality of life of animals can have a direct impact on the health of the community where they live, therefore, knowledge of the number of animals and the conditions in which they are found is fundamental to the development of actions focused on Unique Health. Aiming to carry out a population estimate of dogs and cats, domiciled and semi-domiciled, in the urban area of Barra-BA and to analyze the population's knowledge about the themes "responsible guarding" and "animal welfare", it was carried out, in the period of August to November 2019, the application of a questionnaire in 365 residences. The results showed that for each inhabitant there were about 0.152 dogs and 0.108 cats, thus, it is estimated about 6,341 domesticated and semi-domesticated animals, being 3,707 dogs and 2,634 cats. The analysis of notions of animal welfare and responsible guarding showed that most tutors do not satisfactorily practice responsible guarding, especially for cats that, when compared to dogs, had lower rates of deworming and vaccination, as well as average age below that of the canine population. The number of animals with free access to the street was higher for felines. In terms of reproductive control, between the two species, only 3.6% were spayed. At the end of the work, it can be concluded that the cat: inhabitant proportion in the studied region is consistent with the national proportion. In contrast, the dog: inhabitant relationship was shown to be inferior when compared to national values. Furthermore, there was a need for educational actions within the scope of responsible custody.
Percepções de professores sobre clima educacional na educação infantil de São Bernardo do Campo

Resumo Este artigo apresenta uma pesquisa cujo objetivo foi verificar a percepção de professores da educação infantil de três escolas públicas municipais situadas em São Bernardo do Campo/SP sobre quatro dimensões do conceito de clima escolar: a) as relações sociais e os conflitos na escola; b) as regras, as sanções e a segurança na escola; c) as relações com o trabalho; d) a gestão e a participação. Trata-se de uma pesquisa qualitativa, de caráter exploratório, que utilizou como procedimento de coleta de dados o questionário eletrônico do Clima Escolar elaborado por Vinha, Morais e Moro, em 2017, testado e validado para as escolas brasileiras. O problema da investigação gira em torno das concepções de professores das escolas pesquisadas para compreender se eles concebem como significativo o ambiente social escolar na transformação das unidades escolares em espaços adequados para a convivência sob o marco da democracia. A pesquisa aponta resultados parcialmente positivos, pois os vinte e cinco professores investigados dizem estar satisfeitos com seus gestores e se sentem valorizados em seus ambientes de trabalho. No entanto, um ponto relevante é que as crianças não participam das discussões de regras, as quais são elaboradas somente pelos gestores. As quatro dimensões do clima escolar analisadas são bastante relevantes para a (re)estruturação de ambientes de aprendizagem mais democráticos, colaborativos e autônomos, sobretudo quanto à indicação de criar meios que oportunizem vez e voz ao público da educação infantil, bem como potencializem o trabalho coletivo, autônomo e ético entre professores e gestores.
An improved understanding of the influence of w/c ratio and interfacial transition zone on fracture mechanisms in concrete
Authors: Samal Dinesh K. , Ray Sonalisa
Published: February 2023

The interfacial transition zone (ITZ) is significantly influenced by the water/cementitious materials (w/cm) ratio and governs the overall strength and fracture properties of concrete. Even though an ample number of studies on this topic are available in the literature, there is a lack of unified conclusions pertaining to the influence of w/cm ratios on various fracture characteristics and the underlying mechanisms. In this study, an attempt was made to investigate fracture characteristics (such as the size of the fracture process zone (FPZ), fracture energy, traction-free cracks (TFCs), toughening mechanisms) for varying ITZ properties and water/cement (w/c) ratios. Plain concrete beams of size 700 × 150 × 80 mm (l × d × b) with varying w/c ratios were tested under centre-point loading by controlling the crack mouth opening displacement. The acoustic emission (AE) technique was used to assess the internal damage parameters. A novel method was developed for identifying the TFC tip and the FPZ size using AE event location data at different stages of loading. The role of the ITZ on the fracture mechanisms of different types of concrete was also assessed. Evaluation of the fracture energy revealed that its relation with the w/c ratio is affected by the type of concrete.
The Inflationary Effects of Sectoral Reallocation
Authors: Ferrante Francesco , Graves Sebastian , Iacoviello Matteo
Published: February 2023

The COVID-19 pandemic has led to an unprecedented shift of consumption from services to goods. We study this demand reallocation in a multi-sector model featuring sticky prices, input-output linkages, and labor reallocation costs. Reallocation costs hamper the increase in the supply of goods, causing inflationary pressures. These pressures are amplified by the fact that goods prices are more flexible than services prices. We estimate the model allowing for demand reallocation, sectoral productivity, and aggregate labor supply shocks. The demand reallocation shock explains a large portion of the rise in U.S. inflation in the aftermath of the pandemic.
BUSINESS PROFITABILITY AND MONETARY POLICY OF THE STATE
Authors: Lutsenko S. I.
Published: February 2023

The author examines the features of the management policy and the monetary policy of the state on the profitability of the activities of Russian public companies (business profitability). The tightening of the monetary policy of the state (in particular, the growth of the key rate of the Bank of Russia without reference to the return on assets) may negatively affect the profitability of economic activity. The indicator of dividend payments is a signal for shareholders and potential investors. In addition, dividend payments are an indicator of the financial limitations of companies. Financial constraints are associated with the problem of adverse selection of financing - the choice of a source of financing taking into account its price. Effective management of current assets will allow rational use of them as an additional source of investment. The indicator of the contribution of management or internal growth allows you to evaluate external factors: market fluctuations, macroeconomic features, as well as the actions of financial speculators. This indicator establishes the real contribution of management to the value of the company. Systematic unprofitability of the company’s economic activity is a consequence of short-sighted financial policy or erroneous strategic decisions on the part of management. Management acts in accordance with fiduciary duties of integrity and reasonableness in the interests of the company and its shareholders expecting an increase in the value of the business. Therefore, the management decision should be made from the position of maximising market capitalisation. Then Russian public companies will act in the logic of a precautionary motive, saving a significant part of the funds for subsequent investment in priority projects under conditions of financial restrictions and sectoral sanctions. The growth of sales provides additional opportunities for the company to invest. The Wald, Breusch – Pagan and Hausman tests were carried out in order to identify an adequate forecasting model.
TraceNet: An Effective Deep-Learning-Based Method for Baseline Correction of Near-Field Acceleration Records
Authors: Dong Sheng , Li Zhengbo , Hu Feng , Yu Zhenjiang , Chen Xiaofei
Published: February 2023

In strong ground-motion observations, accelerograms are an important material in both seismic research and earthquake engineering. However, the ubiquitous baseline drift in near-field acceleration records has a large impact on the integrated velocity and double-integrated displacement with linear and parabolic drift, respectively. Conventionally, high-pass filtering and two-stage baseline fitting methods are commonly applied in baseline corrections to obtain reliable strong-motion records. However, these filtering methods exclude low-frequency components from acceleration records and cause unexpected waveform loss. The baseline fitting method, which is based on the experiential selection of intersection moments, is easily affected by external factors and requires a large amount of time for operations. Currently, as the number of accelerometers grows, conventional methods are insufficient in both efficiency and precision to process vast acceleration records. Here, we propose TraceNet, a deep-learning-based method, to correct baseline drifts in velocity records integrated from accelerograms. The training data set is developed with the fusion of artificial baselines and nondrift velocities from corrected accelerations and displacements from events. TraceNet extracts the baseline from the input velocity trace. After TraceNet prediction, the drift can be corrected by subtracting the extracted baseline. In addition, the potential coseismic ground displacement can be recovered from the integration in the corrected velocity. In this study, we used acceleration records and continuous Global Positioning System observations from the 2008 Wenchuan earthquake to demonstrate the ground offset recovery. As a deep learning application, TraceNet can extract and correct the baseline drifts automatically without subjective factors. The coseismic displacements estimated from accelerograms can provide additional insight into the ground deformation.
Representation for Women in Theatre
Authors:   , Garza Abigail , Yau Pamela
Published: February 2023

Women's rights have been challenged, including the recent overturning of Roe v. Wade. The fight for increased or betterment of women's rights throughout the years has been present in multiple areas of life including but not limited to healthcare, voting, and treatment in the workplace. This extended into the theatre and entertainment industry in the way that women have been represented both onstage and in leadership roles within the sector. In this thesis, the representation of women in theatre will be examined within the context of body positivity, feminist views in the arts, and women in leadership positions. Case studies of theatre organizations - 3Girls Theatre Company, Parity Productions, New Perspectives Theatre Company, and SheNYC Arts are studied and analyzed in order to gain an understanding of how representation for women in theatre is ever changing. Improvements are made by providing more opportunities for women, trans, and gender-expansive artists both on stage and in leadership positions, providing more inclusivity, creating educational programs, and connecting with the community. But there is still much more work to be done to fully create a more inclusive theatre industry especially for women, trans, and gender-expansive artists.
Don't Be Suspicious

Published: February 2023

The objective of this research is to explore the phenomenon of pay transparency and if being fully transparent impacts the hiring and recruiting process in arts organizations. Using one- time, semi-structured interviews, I have gathered information on why pay transparency is implemented, how it may affect the recruiting process, and its overall impact on the arts industry. Based on research, pay transparency places value on the candidate's resources, time, and skills, and is deemed a factor in the social and equity issues in the arts industry. Having transparency policies in place can reduce the gender pay gap (Bennedsen et al. 2019), increase the applicant pool (Burke 2016), and contribute to employer profits (Cullen and Paksad-Hurson 2019). As laws continue to be passed (Velie 2022, Liu 2022) and organizations pass transparency policies (Gilmore 2022; Keller 2022; Kozatch 2022; Leach 2022; McGaha and Olson 2022; Sivak 2022; Timmons 2022), we will eventually see pay transparency becoming not just a requirement, but a normal practice across the country.

En términos de turismo comunitario, este conflicto de intereses es aún más agudo debido al impacto potencial en las comunidades cuando el turismo se establece como un modelo económico primario o secundario. En este contexto, la resiliencia comunitaria puede ser un factor decisivo para minimizar los efectos negativos del desarrollo turístico.Este artículo examina la resiliencia comunitaria en el desarrollo del turismo en Valdivia (Ecuador) con el fin de evaluar su papel en el turismo comunitario. El estudio utiliza un marco de planificación e indicadores organizacionales que combina el turismo y la resiliencia comunitaria. La metodología del estudio de caso se enfoca en nueve tipos de acción comunitaria (gestión, calidad del servicio, plan de acción, mercadeo, desarrollo de productos, razones, causas, oportunidades y objetivos) en relación con cinco tipos de capital comunitario que fortalecen la capacidad de una comunidad en tiempos de conmoción. o crisis: humana, social, natural, física, financiera y psicológica. El estudio utiliza un enfoque deductivo basado en técnicas mixtas (cuantitativas y cualitativas) y trabajo de campo.El análisis se centró en los nueve tipos de acciones que realiza la comunidad de Valdivia a través del capital comunitario y sus implicaciones en relación a la resiliencia de la comunidad. Los resultados encontraron que el desarrollo turístico tiene un impacto negativo en varios tipos de acciones comunitarias. Para remediar esto, el estudio propone un marco de gestión para un cambio de paradigma en el modelo de desarrollo turístico para abordar las necesidades organizativas y de planificación de la comunidad, y cambios prácticos de política a largo plazo para el desarrollo y la planificación del turismo basado en la comunidad. Finalmente, el artículo destaca la necesidad de una investigación más profunda para recopilar evidencia empírica sobre los escenarios de mejora tanto en las economías en desarrollo como en las establecidas. Cabe señalar que el desarrollo del turismo comunitario se ha visto interrumpido por la pandemia de COVID-19, particularmente en las comunidades rurales.

The presence of weeds in forest estates is considered one of the biggest problems in the implantation, maintenance, and renovation of eucalyptus plantations. This research aims to evaluate the phytotoxicity of herbicides on eucalyptus and I. nil. The experiment was installed inside a greenhouse in a completely randomized design with five replications. The treatments consisted of the application of 0.2% (v/v) adjuvant with the herbicides: atrazine (2250 g i.a. ha-1), clomazone (720 g i.a. ha-1), sulfentrazone (600 g i.a. ha-1), glyphosate (1440 g i.a. ha-1), and control. The following variables were analyzed: electron transport rate (ETR), water consumption, and plant phytotoxicity. For I. nil plants treated with atrazine, it was possible to detect phytotoxicity previous to the appearance of symptoms in the visual analysis, due to the inhibition of ETR at 24 hours after application (HAA). The highest levels of phytotoxicity for eucalyptus and I. nil were obtained by glyphosate and sulfentrazone, respectively.

3D bioprinting technology is a well-established and promising advanced fabrication technique that utilizes potential biomaterials as bioinks to replace lost skin and promote new tissue regeneration. Cutaneous regenerative biomaterials are highly commended since they benefit patients with larger wound sizes and irregular wound shapes compared to the painstaking split-skin graft. This study aimed to fabricate biocompatible, biodegradable, and printable bioinks as a cutaneous substitute that leads to newly formed tissue post-transplantation. Briefly, gelatin (GE) and polyvinyl alcohol (PVA) bioinks were prepared in various concentrations (w/v); GE (6% GE: 0% PVA), GPVA3 (6% GE: 3% PVA), and GPVA5 (6% GE: 5% PVA), followed by 0.1% (w/v) genipin (GNP) crosslinking to achieve optimum printability. According to the results, GPVA5_GNP significantly presented at least 590.93 ± 164.7% of swelling ratio capacity and optimal water vapor transmission rate (WVTR), which is <1500 g/m2 /h to maintain the moisture of the wound microenvironment. Besides, GPVA5_GNP is also more durable than other hydrogels with the slowest biodegradation rate of 0.018 ± 0.08 mg/h. The increasing amount of PVA improved the rheological properties of the hydrogels, leading the GPVA5_GNP to have the highest viscosity, around 3.0 ± 0.06 Pa.s. It allows a better performance of bioinks printability via extrusion technique. Moreover, the cross-section of the microstructure hydrogels showed the average pore sizes >100 µm with excellent interconnected porosity. X-ray diffraction (XRD) analysis showed that the hydrogels maintain their amorphous properties and were well-distributed through energy dispersive X-ray after crosslinking. Furthermore, there had no substantial functional group changes, as observed by Fourier transform infrared spectroscopy, after the addition of crosslinker. In addition, GPVA hydrogels were biocompatible to the cells, effectively demonstrating >90% of cell viability. In conclusion, GPVA hydrogels crosslinked with GNP, as prospective bioinks, exhibited the superior properties necessary for wound healing treatment.

Complex curved structures of tissues have been recognized to influence the behavior and function of cells. Tissue curvatures sensed by cells are approximately on the millimeter scale. However, previous research mainly focused on the effect of micro- and nano-scale spatial curved structures, underestimating the significance of milli-scale curvature. Here, we employed fused deposition modeling (FDM) with two-stage temperature control, superfine cone-shaped needle, stable air pressure, and precise motion platform for the customized production of homogeneous, precise, and curved fibers; the responses of M-22 cells to FDM-printed curved channels with radii of 1.5 to 3 mm were systematically investigated. The cells aligned with these curved channels and exhibited various aspect ratios in the channels with different curvatures. Cell proliferation, migration speed of single cells, and front-end speed of collective cells were tightly regulated by these curved structures. Also, a computational model based on force equilibrium was proposed to explore the essential factors and mechanisms of curvature affecting cell behavior. Our simulation results demonstrated that the curvature and width of channels, along with the relative size of cells, can significantly impact the cell–boundary interaction force and the number of valid pseudopodia generated by cells in the process of cell migration. These results provide a comprehensive understanding of the effect of milli-scale curvature on the cells and underpin the design of scaffolds that can be produced easily with sophisticated micro- and nano-scale curved features to regulate cell behavior in tissue engineering.

Three-dimensional bioprinting is a technology in constant development, mainly due to its extraordinary potential to revolutionize regenerative medicine. It allows fabrication through the additive deposition of biochemical products, biological materials, and living cells for the generation of structures in bioengineering. There are various techniques and biomaterials or bioinks that are suitable for bioprinting. Their rheological properties are directly related to the quality of these processes. In this study, alginate-based hydrogels were prepared using CaCl2  as ionic crosslinking agent. Their rheological behavior was studied, and simulations of the bioprinting processes under predetermined conditions were carried out, looking for possible relationships between the rheological parameters and the variables used in the bioprinting processes. A clear linear relationship was found between the extrusion pressure and the flow consistency index rheological parameter, k, and between the extrusion time and the flow behavior index rheological parameter, n. This would allow simplification of the repetitive processes currently applied to optimize the extrusion pressure and dispensing head displacement speed, thereby helping to reduce the time and material used as well as to optimize the required bioprinting results.

Past research has identified that individuals from BAME communities face health inequalities and report poorer
outcomes from numerous health interventions. This study will explore some of the reasons with a focus on the
perceptions towards physical activity in the lifestyle prevention of diseases. It will also seek to elicit a
range of facilitators and barriers towards improving physical activity lifestyle choices amongst UK BAME adults,
including but not limited to those in the individual, structural, environmental and social domains. Furthermore,
it will consider the role of ethnicity and culture in the forming of physical activity lifestyle choices. This
study was conducted to explore the facilitators and inhibitors of making healthy physical activity lifestyle
choices amongst UK BAME adults during the COVID-19 pandemic. The study will involve 2 phases: a systematic
review and a qualitative study phase. The systematic review will be conducted using the PECO (Population,
Exposure, Comparison, and Outcome) framework and the preferred reporting items for systematic reviews and
meta-analyses (PRISMA) strategy. The qualitative study will be a semi-structured online personal interview
of a purposive sample of 12 UK BAME adults residing in Teesside, North East of England (UK). The findings
obtained would be useful in designing culturally relevant interventions that seek to improve physical activity
lifestyle choices for UK BAME adults and inform future policy guidelines in the UK.
Saúde Coletiva, pós-estruturalismo e redes vivas de existência: caminhos para pensar o nosso tempo
Authors: Merhy Emerson Elias
Published: February 2023

Pretende-se, nesse material, partir de um problematização da pretensão metalinguística das práticas discursivas, de certos campos disciplinares que atravessam a constituição do campo da saúde coletiva brasileira, com o intuito de criar um campo de novas possibilidades de pensamentos não, necessariamente, já instituídos e validados nesses campos, mas que podem abrir novas possibilidades de produção de conhecimento, ao mesmo tempo que permitam gerar novos temas e objetos de estudo para a saúde coletiva. Toma-se a tensão entre esses campos disciplinares instituídos e a emergência de novas ofertas de pensamentos no que corriqueiramente é tratado como pós-estruturalismo. Fecha-se com a explicitação necessária entre ciência de estado e ciência nômade que tem operado no território expressivo da saúde coletivo.
