Abstract Introduction Remote teaching during the COVID-19 pandemic caused teachers to work under adverse conditions and sit in front of a computer rather than stand, which can lead to musculoskeletal pain and stress in this population. Objective To observe the prevalence of musculoskeletal pain and its correlation with stress levels in teachers during the remote teaching period of the COVID-19 pandemic. Methods A cross-sectional study carried out in elementary and high schools in the city of São José do Belmonte, Pernambuco state (PE). Sixty teachers of both sexes aged 18 years and older were evaluated. The Nordic Questionnaire of Musculoskeletal Symptoms (NQMS) was used to assess musculoskeletal pain, the Visual Analogue Scale to quantify pain intensity and the Maslach Burnout Inventory to identify symptoms of stress and burnout. Results Seventy five percent (n = 45) of the teachers reported musculoskeletal pain, with a higher prevalence in the lumbar spine 68.3% (n = 41), followed by the cervical spine 45.0% (n = 27),thoracic spine, wrists and hands, both with 41.7% (n = 25). A positive correlation was observed between the presence of musculoskeletal pain and high levels of occupational stress (p = 0.036). Conclusion A high prevalence of musculoskeletal pain was identified in teachers during the remote teaching period. The lumbar, cervical and thoracic spine, wrists and hands exhibited the highest pain prevalence. Teachers who experienced musculoskeletal pain had higher stress levels and there was a positive correlation between musculoskeletal pain intensity and high occupational stress levels.

RESUMO A circulação de nudes constitui um fenômeno atual pertencente ao campo amplo do sexting. Este artigo apresenta uma sessão de psicodrama junguiano no tema. O recrutamento foi realizado através de redes sociais utilizando metodologia bola de neve. Foram obtidos dois relatos de jovens de 26 anos. Com a finalidade de exploração dos relatos em maior profundidade, apenas um deles foi dramatizado. Dois fenômenos digitais foram identificados: exposição indevida e ghosting. Emergiram dinâmicas relacionais de teor afetivo-sexual nos nudes que puderam ser compreendidas como associadas ao erotismo na cultura digital. Foram realizadas amplificações mítico-simbólicas pelos mitos de Eros e Psiquê e Lilith. Recomenda-se a elaboração de novos estudos para maior abrangência na compreensão de situações relacionadas a essa prática.

Authors: Brito-Gomes Jorge Luiz de , Barbosa Rhennan Rodrigues , Nunes Samira Maria Socorro , Ferreira Guilherme Bruno Santiago , Costa Manoel da Cunha
Published: December 2022

ABSTRACT To compare measured and estimated metabolic equivalent (MET) and energy expenditure (EE) in different situations with Type-1 diabetes (T1DM) patients. Ten T1DM patients performed three 30-minute sessions (resting, running-RS, and exergame-VS) at moderate intensity. MET and EE were measured by direct gas analyzer and estimated using the formula applying heart rate and V̇02peak. MET values (measured vs. estimated) were statistically different during RS (4.58±1.11 vs.7.59±1.36) and VS (3.98± 0.84 vs. 5.77±0.84) (p<0.001). EE values were similar: RS (147±43 vs. 246±157) and VS (129±33 vs. 184±20) (p<0.001). The error between the methods: 0.41, 1.51, and 1.07 METs and 20.1, 51.5, and 32.5 Kcals for resting, RS, and VS. Estimation could be used in resting and with caution for RS and VS.

Authors: Boscatto Juliano Daniel , Bagnara Ivan Carlos
Published: December 2022

RESUMO O objetivo desse ensaio teórico é analisar os fundamentos teóricos e legais que possuem potencial para contribuir com a compreensão da especificidade da Educação Física no Ensino Médio Integrado à Educação Profissional e Tecnológica. Os dados indicam que o trabalho, ciência, tecnologia e cultura são entendidos como dimensões indissociáveis da formação humana e necessitam estar na base das propostas educacionais dos componentes curriculares no Ensino Médio Integrado. Cabe, então, à Educação Física, a partir do escopo que constitui a cultura corporal de movimento, estabelecer articulações com o campo epistemológico que a compõe e promover integrações curriculares com as demais áreas do conhecimento, possibilitando uma formação emancipatória.
EFICÁCIA DOS AJUSTES ESTRATÉGICOS EM UM MERCADO COMPETITIVO: FOCO EM PEQUENAS EMPRESAS EM UM PAÍS EMERGENTE
Authors: Ngo Quang-Huy
Published: December 2022

RESUMO O objetivo deste estudo é saber como as pequenas empresas em um país emergente melhoram a eficácia dos ajustes estratégicos em relação a intensidade da concorrência no mercado. A pesquisa propõe que, quando a concorrência no mercado é intensa, essas pequenas empresas recorrem as estratégias dos tipos prospectora ou defensiva para melhorar o seu desempenho. Os dados foram coletados de 107 pequenas empresas localizadas no Vietnã. PLS-SEM foi utilizado para avaliar o modelo de pesquisa proposto. Os resultados sugerem que, quando a concorrência no mercado é intensa, apenas ajustes estratégicos com orientação prospectora levam as pequenas empresas a alcançar um desempenho superior. O estudo contribui para a literatura de quatro formas. Em primeiro lugar, amplia a compreensão atual sobre o tema dos ajustes estratégicos ao abordar os efeitos mediadores do tipo de estratégia. Em segundo, contribui para a crescente literatura sobre a teoria da contingência na gestão estratégica de pequenas empresas. Terceiro, a pesquisa oferece uma compreensão mais profunda das características únicas dos países emergentes, características essas que são responsáveis pela ineficiência da estratégia defensiva. Em quarto lugar, o presente estudo supera as limitações de estudos anteriores relacionados ao uso de construtos de item único para operacionalizar as variáveis da estratégia.
Damage assessment & innovation of efficient retrofitting solution of RC slabs exposed to contact explosion
Authors: Metwally Ibrahim Mohamed
Published: December 2022

abstract: Under contact explosions, the reinforced concrete structures can behave in a brittle manner with highly localized damage like concrete cratering, spalling, and reinforcement rupturing. High-speed fragmentation resulting from concrete spall may cause severe casualties and injuries. It is therefore important to restrained concrete fragments and improve collapse resistance of the slab. A new retrofitting technique is proposed in this paper which completely prevents fragmentation. To mitigate blast effects on civil structures, a new kind of concrete material named Ultra-High-Performance-Concrete (UHPC) is now widely studied and applied. UHPC material is known for its high compressive and tensile strength, large energy absorption capacity as well as good workability and anti-abrasion ability compared to normal strength concrete(NRC). All of recent experimental published work concerning blast performance of UHPC slabs under far or near explosion effect, on the other side, the contact explosion tests are relatively limited experimentally and nearly impossible because of security restrictions and costly in terms of both preparation and measurements. So, the real and accurate finite element models are needed to address this gap and understanding the real contact-explosion behavior of both NRC and UHPC slabs. The numerical analyses allow gaining insight into the complex failure mechanisms occurring in the slab and not directly observable. In this study, coupled smoothed particle hydrodynamics (SPH) method and finite element method is utilized to simulate the contact blast tests. Numerical results are compared with the experimental observations, and the feasibility and accuracy of the numerical model are validated. The validated numerical model provided a useful tool for designing potential blast-retrofitting solutions which can prevent the local material damage and fragmentations in both NRC & UHPC slabs subjected to contact explosion. This study introduced adequate and very efficient protection solution for both NRC & UHPC slabs exposed to contact explosion (1 kg of TNT) by utilizing the composite action generated between slabs & bonded steel plates. The 2 mm and 1 mm bonded steel plates at both faces of the NRC and UHPC slabs respectively attained a superior resistance to contact explosion.
Sebekia sp. (Eupentastomida, Sebekidae) in Pygocentrus piraya (Actinopterygii: Serrasalmidae) from marginal lagoons of the middle São Francisco River basin, Brazil
Authors: Duarte Rayane , Santos-Clapp Michelle Daniele dos , Brasil-Sato Marilia de Carvalho
Published: December 2022

Abstract Pygocentrus piraya is an endemic species of the São Francisco River basin. In this study, 342 carnivorous fish were examined, nymphs specimens of Sebekia sp. and its ecological indexes are recorded only in piranhas, of the total of 53 collected from three marginal lagoons of the middle São Francisco River basin: 17 specimens from Curral de Varas lagoon; 15 from Maris lagoon, both of state of Minas Gerais; and 21 specimens from Mocambo lagoon, state of Bahia. The prevalence (P) and mean abundance (MA) of Sebekia sp. nymphs in intermediate hosts were as follows: in Curral de Varas lagoon, P = 11.8%, MA = 0.18; in Maris lagoon, P = 46.6%, MA = 0.47; and in Mocambo lagoon, P = 14.3%, MA = 1.05. Despite the lower number of fish examined from Maris lagoon, this lagoon had the highest number of piranhas (seven) parasitized by Sebekia sp. Pentastomids have zoonotic importance and evaluation of the indirect life cycle of sebekids in lagoons is necessary for defining the intermediate and final hosts involved. This record is novel and stems from collection of piranhas in the marginal lagoons of the São Francisco River, in the states of Minas Gerais and Bahia, Brazil.

RESUMO Este artigo analisa a obra Negra Efigênia, paixão do senhor branco, da escritora Anajá Caetano. O livro trata das relações entre escravos negros e senhores brancos na localidade de São Sebastião do Paraíso (MG). O romance contextualiza o espaço onde transcorre a história. O enredo da obra permite considerá-la um romance de costumes com trânsitos em histórias de fundações de lugares, colocando em questão gêneros literários predominantemente masculinos da época. A origem africana da autora desafia os acontecimentos e a legalidade quando relata, um século após a abolição da escravatura do Brasil, as relações étnicas e raciais.
UM TOLSTOI AFRICANO: ANDRÉ REBOUÇAS E UM OUTRO OCIDENTE (1889–1898)
Authors: Daibert Júnior Robert , Mattos Hebe
Published: December 2022

RESUMO Este artigo tem como objetivo problematizar a escrita de si de André Rebouças durante seu período de exílio na Europa e na África, entre 1889 e 1898. Por meio da análise de sua correspondência ativa no período, pretende-se interpretar sua autocompreensão como um “Tolstoi Africano”, vista como expressão de uma dupla consciência enquanto intelectual ocidental e negro no final do século XIX, como proposto por Paul Gilroy (2001: 33-39) no primeiro ensaio do livro The Black Atlantic (1993). O artigo propõe-se a compreender em que aspectos a mobilização do pensamento de Tolstoi a partir do final dos anos 1880 se relaciona com a redefinição de seu pensamento racial e lhe permite transitar, em base universalista e cristã, para um pensamento crítico da modernidade liberal.

Authors: Nascimento Silvana de Souza
Published: December 2022

RESUMO Este artigo pretendeu debater epistemologias trans negras com base numa produção brasileira elaborada por intelectuais transfeministas. A proposta é refletir sobre um campo de conhecimento emergente e apontar seus aspectos transversais: a desnaturalização da categoria mulheres e feminilidades, a autodefinição, a perspectiva interseccional, a despatologização, a luta contra o cissexismo e o racismo, e a multiplicidade identitária. Com destaque para ativistas, pesquisadoras e docentes, o texto apresenta convergências e tensões entre esta produção de conhecimento e certas correntes da teoria feminista e do pensamento feminista negro.
A ocupação de Alcatraz e o movimento indígena nos Estados Unidos (1969-1971)
Authors: Alves Junior Alexandre Guilherme da Cruz
Published: December 2022

Resumo: O artigo analisa os pronunciamentos e as ações realizadas pelos ativistas indígenas que ocuparam a ilha de Alcatraz entre novembro de 1969 e junho de 1971. Na ocasião, um grupo de estudantes chegou à antiga prisão federal, intitulando-se “Indígenas de Todas as Tribos”, com o objetivo de reclamar o território para a fundação de um centro cultural e uma universidade indígenas. Através da análise de seus manifestos públicos buscaremos compreender como uma leitura própria do passado foi utilizada tanto como instrumento de legitimação das ações políticas de ação direta não violenta, visando a autodeterminação dos povos indígenas nos Estados Unidos, como também instrumento para forjar uma agenda interétnica, que pudesse reverter as péssimas condições sociais dos povos nativos nos centros urbanos e nas reservas.
O desafio dos museus históricos celebratórios
Authors: Rollemberg Denise
Published: December 2022

Resumo: O artigo visa a contribuir para o debate em torno da tensão presente em museus históricos de temáticas ligadas à Segunda Guerra Mundial entre narrativas celebratórias de certos fatos e personagens (memória) e narrativas críticas próprias à natureza da pesquisa histórica. Tal tensão aparece tanto em museus europeus, como norte-americanos. Como desdobramento dessa discussão, aborda também os conflitos em torno da criação de museus históricos dedicados a assuntos tais como fascismo, nazismo, colaboração, na Europa.
The symbolic landscape of an illiberal regime: glorifying the interwar era in post-2010 Budapest
Authors: Erőss Ágnes
Published: December 2022

Abstract: Since 2010 the Fidesz party, led by Viktor Orbán, has gradually eroded democratic institutions in Hungary using methods commonly applied by illiberal and authoritarian regimes. Previous studies explored how memory politics play a crucial role in maintaining the populist rhetoric, essential for Fidesz rule. This article aims to shed light on the spatial representation of Fidesz power in urban space. Drawing on the literature of symbolic space appropriation in general and the memory politics of Fidesz in particular, I analyze the transformation of two emblematic, centrally located squares in the capital of Hungary: Liberty and Kossuth Square. I argue that the interventions/transformations of these squares inscribe the re-evaluated and distorted “official” narratives of national history into the landscape, turning these places into a hallmark of the populist and illiberal character of Fidesz’ rule.
Levelling the playing field: A Review of Mentoring in the CaBan Initial Teacher Education programme
Authors: Jones Luke , Tones Steven , Foulkes Gethin , Jones Rhys C.
Published: December 2022

The aim of this paper is to examine the impact of the new CaBan Initial Teacher Education (ITE) programme that has emerged in response to broader educational reform in Wales. More specifically, it aims to analyse the perceptions of mentors and Associate Teachers (ATs) to develop a more adequate understanding of the mentoring approach that has been adopted by CaBan. Questionnaires and group interviews were used to generate data from 15 mentors and 48 ATs – who took part in the study during the final phase of their one-year postgraduate programme. A process of thematic analysis was used to identify and analyse patterns in the data. The dialogic mentoring approach adopted by CaBan reframed the relationship between the mentor and AT. It encouraged a more democratic partnership that empowered the ATs to challenge some aspects of practice and engage in more creative acts. Regular feedback and discussions that were focused on shared learning helped reduce ATs’ evaluation apprehension, but also created some tension as mentors’ pedagogical beliefs were more likely to be challenged. These findings have implications for the CaBan programme and other providers of ITE, as adopting a dialogic approach led to desirable changes in mentoring strategies. These changes were perceived to be valuable, but they relied on the mentors devoting more time to the dialogic process and being fully invested in open conversations about learning.
Adoption of BOT Model to Introduce Vaccines: Tablet Approach
Authors: AD Roy , A Ray , RS Ghosh , S Bagchi , P Haldar
Published: December 2022

Objective: The introduction of the rotavirus vaccine (RVV) in India is one of the major achievements of the immunization program of India. Faced with various challenges, including different product specifications and competing for other program priorities, the introduction of the rotavirus vaccine in the universal immunization program was a monumental task. Considering the successful introduction of RVV, there is a need for a knowledge transfer tool that can enable policymakers and other countries to adopt it to formulate informed strategies and introduce new vaccines. Methods: The review was conducted in two phases. In the first stage, a literature review was conducted to identify and analyze all the published literature on Build-Operate-Transfer (BOT) model and RVV introduction in India. In the second phase, an analysis of the shortlisted literature was conducted utilizing the framework method. Results: Following the analysis, several similarities were observed between the approach to rotavirus vaccine introduction, and BOT model. Hence, based on the above analogy new public health project implementation framework, TaBLET (Technical Advice, Build capacity, Leverage partnerships, Engineer innovations, Transfer assets) approach, was proposed. Conclusion: This article has proposed a new TaBLET approach adapted from the BOT model. The RVV introduction has shown that a project implementation framework like TaBLET can be successfully employed for efficiently utilizing existing resources, increased outreach with existing human resources, and complete transfer of tangible and intangible assets, which can be imbibed in the existing health system. This article highlights the genesis and the multifactorial benefits of the TaBLET approach in introducing new vaccines as well as in other allied health care programs.
Exhaustification in the semantics of cause and because
Authors: McHugh Dean Michael
Published: December 2022

We show that a single operation can account for three seemingly distinct properties of the semantics of cause and because. The properties are, firstly, their comparative nature: interpreting cause and because involves comparing what would happen in the presence of the cause (a positive condition) with what would happen in the absence of the cause (a negative condition). Secondly, there is an asymmetry in logical strength between the two conditions: the positive condition involves a universal modal while the negative condition involves an existential modal. Thirdly, the positive and negative conditions have the same modal base, i.e. are interpreted while assuming the same set of background facts.Despite their apparent dissimilarity, we show that these three properties are predicted by a single operation: exhaustification. The comparative nature of cause and because follows from the comparative nature of exhaustification, which compares a sentence with its alternatives. The asymmetry in strength arises because exhaustification negates alternatives: given the duality between universal and existential quantification, negation flips a necessity modal into a possibility modal, producing the observed strength asymmetry. Finally, the positive and negative condition have the same modal base since, rather cause and because having two modals in their semantics—one for the positive condition and one for the negative condition—their semantics contains a single modal which is copied by exhaustification.We conclude by showing that this exhaustification operator violates Economy constraints, suggesting that it is not subject to licensing conditions but part of lexical semantics of cause and because.
Physician Advocacy: Identifying Motivations for Work Beyond Clinical Practice
Authors: Warwick Sophia , Kantor Laura , Ahart Erin , Twist Katie , Mabry Terrance , Stoltzfus Ky
Published: December 2022

Introduction. Advocacy is a perceived social and professional obligation of physicians, yet many feel their training and practice environment don’t support increased engagement in advocacy. The aim of this qualitative project was to delineate the role advocacy plays in physicians’ careers and the factors driving physician engagement in advocacy. 
Methods. We identified physicians engaged in health advocacy in Kansas through personal contacts and referrals through snowball sampling. They received an email invitation to participate in a short in-person or phone interview which was recorded using Apple Voice Memos and Google Dictation. Two team members independently identified themes from interview transcripts, while a third member served as a moderator if themes identified were dyssynchronous. 
Results. Of the 19 physicians invited to participate, 13 were interviewed. The most common reasons for engaging in advocacy included the desire to change policy, obligation to go beyond regular clinic duties, giving patients a voice, and avoiding burnout. Physicians reported passion for patients and past experiences with disparities as the most common inspiration. Most physicians did not have formal advocacy training in school or residency, but identify professional societies and peers as informal guides. Common support for advocacy were professional organizations, community partners, and employers. Time was the most common barrier to conducting advocacy work. 
Conclusions. Physicians have a broad number of reasons for the importance of doing advocacy work, but identify key professional barriers to further engagement. Providing accessible opportunities through professional organizations and community partnerships may increase advocacy participation.
Tecnologia de Reconhecimento Facial e Segurança Pública nas Capitais Brasileiras: Apontamentos e Problematizações
Authors: Melo Paulo Victor , Serra Paulo
Published: December 2022

A partir da identificação e análise de propostas apresentadas por gestores públicos municipais, o presente artigo tece apontamentos sobre a relação entre tecnologias digitais e segurança pública no Brasil. Como corpus de pesquisa, foram selecionados os programas de governo elaborados pelos atuais prefeitos de todas as capitais do país na última eleição municipal (2020) e protocolados no Tribunal Superior Eleitoral. Como principais resultados da análise, apontam-se aqui: a previsão de uso de tecnologias digitais na segurança pública por 15 dos atuais 26 prefeitos de capitais, a pulverização partidária e a diversidade geográfica desses gestores, o ocultamento de potenciais problemas na aplicação dessas tecnologias. Adotando as noções de capitalismo de vigilância (Zuboff, 2018/2020) e racismo algorítmico (Silva, 2019) compreende-se em termos conclusivos que, sobretudo em um país marcado pelo racismo estrutural, as tecnologias digitais aplicadas à segurança pública devem ser pautadas considerando as possíveis implicações éticas, sociais, políticas e culturais, de modo que, na busca pelo combate à criminalidade e por ampliação da segurança, não se perpetue violências contra grupos historicamente discriminados.
“I Need Ammunition, Not a Ride”: The Ukrainian Cyber War
Authors: Munk Tine , Ahmad Juan
Published: December 2022

The Russian invasion of Ukraine in February 2022 has shown that cyberwarfare is integral to modern military strategies. Although the Russian army has developed cyber capabilities and capacities over the years, Ukraine has quickly created a new and innovative cyber defence that includes public and private actors. Using online communication platforms to reach out to populations, internally and externally, has been instrumental for military success. Inventive thinking has enabled the actors to utilise the online space and develop new computing tactics to defend the country. The intense online presence of Ukrainian President Zelenskyy stands in clear contrast to Russian President Putin. President Zelenskyy is mastering online communication and is speaking directly to the people. Because of his constant use of virtual communication platforms, new public and private resistance movements have formed based on civic activism and a defiant stance against Russian aggression. Various non-governmental groups of hackers, hacktivists and activists have created a structure of resistance, where each has taken on a role in a nodal system depending on skills and engagement levels. This article will focus on how the Ukrainian leadership has been able to carry out a successful speech act that has activated numerous online users internally and externally. This speech act has enabled a new form of online civic activism where online actors fight with the military forces — but mostly without being employed by the state. Within the first 40 days, this activism has proven beneficial to the existing military force to defend Ukraine. The article investigates Ukraine’s role in the David and Goliath fight and how Ukraine’s initiatives have helped develop its cyber defence. The research is based on secondary sources predominately based on grounded theory, where the data collected are critically compared with theoretical content. All data is theoretically sampled and analysed based on the established socio-political approaches deriving from discourse analysis. The timeframe for this research is the first 40 days of the conflict, starting on February 24 2022.
A Narrativa Jornalística no Twitter de um (Não) Atentado em Portugal
Authors: Antunes Eduardo
Published: December 2022

Quinta-feira, dia 10 de fevereiro de 2022, “um estudante de 18 anos foi detido esta quinta-feira pela Polícia Judiciária suspeito do crime de terrorismo, já que estaria há meses a planear atacar os colegas da Faculdade de Ciências da Universidade de Lisboa” (Henriques et al., 2022, para. 1). Um caso sem grande paralelo em Portugal, num contexto mediático caracterizado pelo que é imediato e pela crescente importância das redes sociais e média sociais, como o Twitter, inclusive para a circulação de informação. Parte-se de um entendimento do Twitter como uma plataforma relevante para o jornalismo contemporâneo que conecta fluxos de informação entre partes (Bennett & Segerberg, 2012; Sadler, 2018). Foram extraídos 3.577 tweets no espaço de 1 semana desde o caso, das cinco contas oficiais no Twitter com mais seguidores, de cariz jornalístico/informativo em Portugal. Desses, apenas 104 tweets se focam neste particular caso, destacando-se o facto de o Correio da Manhã apresentar o triplo de tweets do Expresso. Este trabalho utiliza uma abordagem qualitativa para realizar uma análise discursiva, com recurso a nuvens de palavras, que representam visualmente a frequência de termos. A identificação de narrativas, inclusive macro e micronarrativas (Lits, 2015; Motta, 2013), orienta este trabalho, que resulta na identificação da macronarrativa da existência de um ataque numa faculdade da Universidade de Lisboa. A narrativa do terrorismo, apesar de comum no corpus geral não é central, já que se encontra de forma não uniforme entre as cinco nuvens de palavras, sendo identificada nas nuvens de palavras da SIC Notícias, do Jornal de Notícias e do Correio da Manhã. A análise desenvolvida procura auxiliar o desenvolvimento de entendimentos sobre as narrativas utilizadas para dar e construir sentido à cobertura mediática deste caso específico sem grande comparação em Portugal.
Влияние социально-экономических и демографических факторов на вероятность рождения недоношенного ребенка
Authors: Щевьёва Любовь Сергеевна
Published: December 2022

В последние годы в Москве, как и в мире, наблюдается тенденция увеличения среднего возраста матери при рождении детей, что может приводить к увеличению вероятности мертворождения или рождения недоношенного ребенка, возможной окончательной бездетности, а также к плохому воздействию на состояние здоровья матери (Selvaratnam 2014: 4). На смещение пика первых рождений в 2018 г. на возрастную группу 24-26 лет, а вторых рождений на возрастную группу 31 год в России (Российская экономическая школа 2022) и в Москве в частности сказалось влияние материнского капитала как меры семейной политики, введенной в январе 2007 г. Для предотвращения патологий и отрицательных исходов беременности правительства в развитых странах предпринимают меры по наблюдению за здоровьем женщин, рожающих в более позднем возрасте, что важно для состояния женщин до, во время и после завершения беременности, и для здоровья их будущих детей. Необходимо модернизировать и российскую систему ведения беременности для обеспечения беременных и рожениц разных возрастов более качественными медицинскими услугами.

В данном исследовании была сформирована база данных на основе 15 тыс. обезличенных сканов медицинских свидетельств о рождении в московском регионе за 2011-2017 гг. С использованием Logit-моделей было подтверждено, что с увеличением возраста матери растет вероятность рождения недоношенного ребенка. При этом с каждым последующим ребенком также увеличивается вероятность недоношенности. Результаты оказались устойчивыми при добавлении ряда переменных в модель, таких как наличие высшего образования, очередность рождения и постановка на учет до 12-й недели беременности.

En el presente trabajo se argumentan las razones por las cuales el binomio Cuniculus hernadezi Castro, López y Becerra, 2010, no constituye un nombre disponible de acuerdo a la reglamentación del vigente Código Internacional de Nomenclatura Zoológica (ICZN). Entre estas razones se encuentran la carencia de una descripción precisa y la no asignación de un ejemplar tipo. Adicionalmente, resaltamos problemas en el diseño de la investigación en la cual el binomio fue descrito, que afectan las conclusiones acerca de una distinción taxonómica entre las poblaciones de las cordilleras Oriental y Central de Colombia.
Principales amenazas a la biodiversidad marina
Authors: Mancera-Pineda José E. , Gavio Brigitte , Lasso-Zapata Jairo
Published: December 2022

Evaluaciones recientes sobre el conocimiento de la biodiversidad registran que las especies marinas corresponden apenas a un 15% del total de los taxones conocidos en el planeta. La falta de conocimiento de la diversidad marina se suma a una acelerada tasa de pérdida de la misma, debido esencialmente a causas antropogénicas. El objetivo de este trabajo es presentar una revisión de las principales amenazas de origen humano a la biodiversidad marina, tales como sobrepesca, descarga de nutrientes, derrames de petróleo, destrucción de hábitat, bioinvasiones, florecimientos algales nocivos y cambios globales. Cada una de estas amenazas pone en riesgo una o varias especies, y a largo plazo, modifica hábitats y ecosistemas completos, causando una pérdida de biodiversidad, muchas veces difícil de evaluar. Mientras en los ecosistemas terrestres el principal factor de riesgo es la destrucción de hábitat, en ambientes marinos la sobreexplotación de recursos es la causa principal de pérdida de biodiversidad. La percepción que los ecosistemas marinos son más resilientes a los disturbios que los ecosistemas terrestres necesita ser reevaluada, ya que probablemente no corresponde a la realidad.
Cambios en los retornos de la educación en Bogotá entre 1997 y 2003
Authors: Forero Nohora Y. , Gamboa Luis Fernando
Published: December 2022

Este artículo estima la tasa de retorno de la educación de la población asalariada en Bogotá para 1997 y 2003 teniendo como referencia la teoría del capital humano. Para la estimación se corrige el sesgo de selección por medio de la metodología de Heckman (1979). A diferencia de estudios anteriores, que usan la Encuesta Nacional de Hogares, en éste se utiliza la información disponible en la Encuesta de Calidad de Vida que también es representativa para Bogotá. Se encuentra que los retornos de la educación y de la experiencia potencial, así como la elasticidad horas-ingreso laboral y el ingreso laboral se reducen en el periodo posterior a la recesión económica.   Palabras clave: ecuación de Mincer, retorno de la educación, sesgo de selección, teoría del capital humano. Clasificación JEL: C24, J31, J24, J38.   Abstract:   This paper estimates the returns to education in Bogotá in 1997 and 2003 by means of Heckman’s maximum likelihood methodology. The analytical framework used is Human Capital Theory. Instead of using the ‘Encuesta Nacional de Hogares’ (National Household Survey), as does current literature, we use the ‘Encuesta de Calidad de Vida’ (Life Quality Survey). We found a reduction after the economic recession (1999) in aspects such as the returns to education and the impact of experience in Bogotá between these years. There are also suggestions about a decrease in the labor income and in the hour-income elasticity.   Keywords: Mincer equation, returns to education, selection bias, human capital theory. JEL classification: C24, J31, J24, J38.   Résumé:   Cet article calcule le taux de rendement de l’éducation sur le salariat dans la ville de Bogotà entre 1993 et 2003 dans le cadre de la théorie du capital humain. Pour ce faire, nous utilisons la méthodologie proposée par Heckman (1979) qui permet de corriger les biais de sélection. Nous utilisons les données disponibles dans l’Enquête de Qualité de Vie au lieu de l’Enquête Nationale pour les Foyers, les deux enquêtes étant significatives pour la ville de Bogotà. Nous montrons que les taux de rendement de l’éducation et de l’expérience potentielle ainsi que l’élasticité heurs-revenu du travail et le revenu du travail, se réduisent pendant la période qui a suivi la récession économique.   Mots clés: équation de Mincer, rendement dans l’éducation, biais de sélection, théorie du capital humain.

Authors: Arango Luis Eduardo , Arias Fernando , Flórez Luz Adriana , Jalil Munir
Published: December 2022

Utilizando la metodología de Bry y Boschan (1971), este trabajo propone fechas precisas para los ciclos de negocios ocurridos en Colombia entre 1980 y 2007 identificando las fases de auge y recesión. Durante el período de análisis se presentaron cinco ciclos de negocios completos, los cuales, al igual que en el caso de Estados Unidos son asimétricos en el sentido que, las fases de expansión duran más que las de recesión. En promedio, los ciclos en Colombia entre 1983 y 2007, según el IPI (índice de la producción industrial) fueron de 45,6 meses, es decir, 3,8 años aproximadamente. Los ciclos más largos de la muestra se dieron a finales de los años ochenta y mediados de los años 90, con duraciones promedio de 68 meses. Palabras clave: ciclo de negocios, fases del ciclo, hechos estilizados, probabilidades. Clasificación JEL: E32, E23. Abstract: By using the methodology of Bry and Boschan (1971), this work proposes precise dates for the business cycles occurred in Colombia between 1980 and 2007 identifying the phases of boom and slump. During the sample period, five complete cycles were detected, which happened to be asymmetric such as those of the United States. This means that expansions are longer than recessions. On average, the cycles in Colombia between 1983 and 2007, according to IPI (Industrial Production Index), were of 45.6 months (3.8 years) approximately. The longer cycles occurred at the end of eighties and mid nineties with average durations of 68 months. Keywords: business cycles, phases, stylized facts, probabilities. JEL Classification: E32, E23.

Disposición a pagar para mejorar la calidad del aire en Talca, Chile: comparación entre usuarios y no usuarios de chimeneas a leña Arcadio Cerda, Leidy García, Alejandra Bahamondez y Viviana Poblete Resumen: El objetivo de este estudio es analizar la diferencia en la disposición a pagar de usuarios y no usuarios de leña, por un mejoramiento en la calidad del aire para los habitantes de la Florida, Talca. Se utilizó el método de valoración contingente en su formato dicotómico doble, asumiendo una función lineal y una distribución logística para determinar la disposición a pagar por una mejora en la calidad del aire, vía la creación de un organismo certificador de leña seca. La disposición a pagar obtenida alcanzaría para cubrir los costos del organismo certificador, abriendo la posibilidad de aplicar un cobro municipal por dicho concepto; además, las personas que usan leña están dispuestas a pagar menos que quienes no la utilizan.
Capacidad antioxidante y contenido de fenoles totales en café y subproductos del café producido y comercializado en Norte de Santander (Colombia)
Authors: FONSECA GARCÍA Libia , CALDERÓN-JAIMES Lilia Socorro , RIVERA María Esther
Published: December 2022

Antecedentes: El café, una de las bebidas más consumidas en el mundo, contiene varios compuestos bioactivos como los antioxidantes, que han demostrado eficacia en reducir la incidencia de enfermedades crónicas y neurodegenerativas. Como Norte de Santander es la cuna del café en Colombia, resulta relevante estudiar las propiedades antioxidantes de su café y de la industria del café, que ofrece varios productos que se pueden usar como fuente de sustancias funcionales. Objetivo: Evaluar la capacidad antioxidante y determinar el contenido de fenoles totales en el café producido y comercializado en Norte de Santander (Colombia) y en sus residuos o subproductos. Métodos: Las muestras comerciales se seleccionaron mediante una encuesta aplicada en 12 municipios de Norte de Santander. Las almendras y los residuos de café provinieron de los municipios de Toledo y Lourdes. La capacidad antioxidante se evaluó por los métodos FRAP y ABTS y el contenido de fenoles totales se determinó por Folin Ciocalteu (FC). Resultados: El contenido de fenoles totales se encontró entre 1129 ± 0,000 y 2582 ± 0,000 mg EAG/g café, y entre 52,57 ± 4,767 y 1904 ± 8,288 mg EAG/ g café, para las muestras comerciales y sin tostar, respectivamente. La capacidad antioxidante en las muestras comerciales varió entre 3095 ± 0,000 y 6857 ± 8,115 para FRAP, y entre 224,0 ± 0,245 y 245,0 ± 0,000 µmol Etrolox/ g café para ABTS. En el caso de las almendras y los residuos, la capacidad antioxidante varió entre 2,265 ± 0,000 y 1894 ± 1,627 por FRAP, y entre 71,78 ± 0,000 y 233,0 ± 0,000 µmol Etrolox/ g café por ABTS. Conclusiones: Todas las muestras presentaron capacidad antioxidante y fenoles totales, incluidos los residuos del procesamiento del café tales como el pergamino, la cáscara y la pulpa de la cereza. Por lo tanto, se confirma el potencial de los residuos de café como fuentes naturales de antioxidantes. Esta investigación reporta por primera vez propiedades antioxidantes en el pergamino y en cafés especiales.
Cross-embedded ralationship nature of Human Rights-related treaties and instruments with environment-related sustainable development goals
Authors: Suresh B. , Sundaram Asha
Published: December 2022

It is imperative that Treaties & Instruments and United Nations Sustainable Development Goal (SDG) must be analysed, considering their interdependencies and mutually reinforcing nature. The paper examines the Cross Embedded Relationship (CER) nature of core Human Rights-related Treaties & Instruments (HR-T&I) in Environment-related SDGs (E-SDG) in driving a metamorphic transformation process toward inclusive economic growth, adhering to human rights values that are environmentally centric and sustainable in the true sense. Some core HR-T&I explicitly recognise CER, as observed in textual analysis. The study reveals a varied level of the Cross Embedment Relationship Index (CERI) between the provisions of core HR-T&I and E-SDG, thereby indicating the importance of human rights principles in E-SDG and the significance of environment orientation in core HR-T&I. Linking core HR-T&I provisions with E-SDG and extra-legal compliance mechanism of SDGs can produce positive synergies in realising SDG objectives.
Reasons for Internet Users Using Fake Identity from an Islamic Perspective
Authors: Al-Abri Khalid Hassan
Published: December 2022

Among internet users are those who hide their true personalities by having several identities and names on different sites. This research requires years of personal experience, careful observation, and analysis, which the researchers try to relate to reality. This paper discusses the consequence of fake accounts on the internet. The results of this study suggests one person may have multiple identities on different sites. As a result, the internet has become a hotbed for anyone to write and act irresponsibly. In the Islamic view, the reasons internet users have for hiding their real identities, can be divided into two categories; namely, acceptable and unacceptable or wrongful. Acceptable reasons include the need to protect identity, preventive measures, and fear of harm. Unacceptable or wrongful reasons include, harassment and spying.
