Resumo: Este trabalho objetivou conhecer o funcionamento das políticas públicas para mulheres no sertão do estado de Pernambuco. Inicialmente tratou-se as definições das políticas públicas para mulher e de gênero. Num segundo momento a partir da aplicação de um questionário semiestruturado analisou-se o perfil socioeconômico das mulheres e o uso de políticas na cidade de Salgueiro-PE. Os resultados obtidos revelaram que a maioria das mulheres precisam de políticas públicas alguma vez na vida, mostra que a existência de política de gênero ainda é muito falha na região, já que perguntadas sobre a existência de algum programa no município de análise que especialize mulheres em trabalhos que são ditos para homens, cerca de 90% respondeu não saber. Além disso, mesmo em meio a tanta discussão sobre o tema, os dados sugerem que ainda há muito preconceito em relação ao gênero feminino. Abstract: This work aimed to know the functioning of public policies for women in the outback of the state of Pernambuco. Initially, the definitions of public policies for women and gender were dealt with. In a second step, from the application of a semi-structured questionnaire, the socioeconomic profile of women and the use of policies in the city of Salgueiro-PE were analyzed. The results obtained revealed that the majority of women need public policies at some time in their lives, it shows that the existence of gender policy is still very flawed in the region, as they are asked about the existence of any program in the municipality of analysis that specializes women in jobs that are said for men, about 90% said they did not know. In addition, even in the midst of so much discussion on the topic, the data suggest that there is still a lot of prejudice against the female gender.Keywords: Gender Inequality; Woman; Public Policy; Gender Policy; Pernambucano Outback.

Resumo: Este texto discute resultados de uma pesquisa sobre a influência da vulnerabilidade social no processo ensino-aprendizagem, realizada em uma escola pública no interior do Nordeste do Brasil. Pesquisas referem que a vulnerabilidade social de comunidades interfere nas oportunidades educacionais. São evidenciados mecanismos capazes de produzir vínculos intrínsecos entre vulnerabilidade social e produção da desigualdade escolar, como representações sociais desfavoráveis às populações residentes em áreas vulneráveis das cidades, falta de equipamentos públicos nos territórios, desequilíbrio familiar e escassos investimentos públicos em educação e cultura nestes espaços. Logo, este trabalho teve por objetivo analisar, através de um questionário, a percepção de professores de uma escola pública, localizada em comunidade rural no interior do Ceará, quanto à influência da vulnerabilidade social na efetivação da escolarização básica. Assim, interfaces determinantes deste paradigma social podem ser identificadas, dimensionadas, servindo de base para a definição de medidas de prevenção e de enfrentamento aos problemas que afligem crianças e suas famílias.Palavras-chave: Pedagogia do abandono, Vulnerabilidade social, Aprendizagem.

Abstract: Cerebrovascular Accident (CVA) is a neurological disorder whose pathophysiology of ischemic side occurs together with the development of a central inflammatory process. Thus, omega-3 fatty acids appear as a potential agent in the prevention and treatment of the repercussions of this ischemic event. This work aims to develop a systematic review of the literature on the neuroprotective potential of omega-3 in terms of preventive and therapeutic aspects in ischemic stroke. A bibliographic review was carried out in the PubMed and Scopus electronic databases, and 12 indexed articles were included in the final sample and applied for discussion. Studies have pointed to the decrease in omega-3 as harmful to nerve tissue regeneration, as well as the neuroprotective role of omega-3 in cerebral ischemia after ischemia-reperfusion injury in animal models. Reduction of cerebral edema, promotion of angiogenesis, preservation of the integrity of the blood-brain barrier and tissue protection were also observed.Keywords : Cerebral ischemia. Omega-3 Polyunsaturated Fatty Acids. Neuroprotection. Resumo: O Acidente Vascular Encefálico (AVE) é um distúrbio neurológico cuja fisiopatologia do lado isquêmico ocorre juntamente com o desenvolvimento de um processo inflamatório central.

El artículo presenta los resultados de la investigación titulada La competencia literaria desde la biblioteca escolar, proyecto de aula para formar lectores literarios en grado noveno. El propósito es dar cuenta del fortalecimiento de la competencia literaria a partir de un proyecto de aula centrado en la biblioteca escolar. Dicha competencia encuentra en la biblioteca el espacio privilegiado para potenciar las capacidades de comprensión y producción de textos literarios con los conocimientos, actitudes y habilidades adquiridos en las experiencias de lectura. La metodología empleada se enmarca en el enfoque cualitativo y el diseño investigación-acción a través de un proyecto de aula que tiene en cuenta los intereses, deseos y necesidades de estudiantes. Los cimientos conceptuales se encuentran en autores como Lomas, Rosenblatt y Mendoza, pues pensar en una práctica social de lectura hace posible la formación del lector autónomo, que comprende cómo se ha dado significado a la vida. Los hallazgos giran en torno a los aspectos de la competencia literaria que se fortalecen con un proyecto de aula; las implicaciones de la implementación de la biblioteca escolar para fomentar hábitos de lectura, y la manera en la que un proyecto de aula sobre la biblioteca escolar permite mejorar la educación literaria. En conclusión, la formación en competencias literarias en relación con la biblioteca escolar conduce a la formación de lectores literarios, que asumen la práctica social de lectura a través de su participación.
Experticia escrituraria en inglés como lengua extranjera (EFL): definiciones en la literatura y autorrepresentaciones de investigadores
Authors: Mirallas Carolina Andrea , Pascual Mariana
Published: May 2022

A pesar de la popular distinción entre hablantes nativos y no nativos de inglés, la participación en la academia y la ciencia de escritores cuya lengua materna no es el inglés es cada vez mayor, por lo cual resulta relevante proponer diferenciaciones en términos de experticia escrituraria. En este trabajo analizamos las definiciones disponibles en la literatura sobre escritores expertos y principiantes sobre la escritura académica y científica, y contrastamos una de ellas con las autorrepresentaciones que construyen los escritores de ciencia en sus relatos. Para ello, entrevistamos a 18 investigadores de una universidad pública argentina. Los datos recogidos se analizaron según categorías emergentes de significados experienciales relacionados con la experticia reportada. Determinamos que una de las definiciones empleada con mayor frecuencia por lingüistas en los estudios del inglés para propósitos específicos (IPE) y académicos (IPA) es aquella que caracteriza a los escritores según el género que producen; así, los expertos escriben artículos de investigación y los principiantes escriben tesis doctorales. Al ser contrastada con las autorrepresentaciones, observamos que esta definición no coincide con las de investigadores/escritores en disciplinas como química, bioquímica, física, matemática y geología, por cuanto las categorías se vinculan con las actividades que desarrollan al interior de los grupos de investigación y con los requisitos institucionales con respecto a la publicación de artículos de investigación para la graduación. Finalmente, resaltamos la necesidad de complementar las definiciones de la literatura con elementos que deriven de una caracterización situada que tenga en cuenta las percepciones de los propios investigadores.

Published: May 2022

This research aimed to analyze the sustainability of beef cattle farming in smallholder farms with semi-intensive and intensive production systems in the South Konawe Regency. It was conducted in West Ranomeeto and Konda sub-districts through Participatory Rural Appraisal with 55 farmers in the semi-intensive system and 50 farmers in the intensive system. The secondary data were obtained from literature, reports, and publications. The sustainability analysis was determined based on selected indi-cators in each aspect. The indicators of economic aspect were livestock income, feces utilization, sav-ings and insurance. The indicators of environmental aspect were concentration of E. coli, fecal coli-form, total coliform, nitrate, and Fe. The sindicators of social aspect were land ownership, livestock health, mortality, area of pen, and dry matter consumption. The analysis results showed that the total value of the economic, environmental, and social aspect indicators in semi-intensive and intensive pro-duction systems was -0.45 and +0.17; -1.15 and -3.85; -0.10 and +0.27, respectively. Meanwhile, the total indicator value in both production systems was -0.57 and -1.14. It can be concluded that both beef cattle production systems in South Konawe Regency carried out by smallholder farmers have not sus-tainable.
Pour un usage critique des sources non musulmanes sur les débuts de l’Islam : compte rendu de Stephen Shoemaker, A Prophet Has Appeared: The Rise of Islam through Christian and Jewish Eyes. A Sourcebook
Authors: Pierre Simon
Published: May 2022

This contribution presents some critical discussions on Stephen Shoemaker’s last Sourcebook as well as two of the author’s publications from 2012 and 2018. His thesis defends the possibility of Muḥammad being an “eschatological Prophet” of an ecumenical messianic movement whose supporters attempted to rewrite his confessional message and communal identity to adapt their religious ideology to the reality of their leader’s death. We first recall that Muḥammad appears in the older Syriac sources as a political leader, never as a Prophet, and that the eschatological moment is more probably the late First century than the time of the conquest. Concerning the vocabulary issue, we show that his revolutionary idea of calling the Ṭayyōyē “Nomads” – while “Saracens” inconsistently remains – might be irrelevant, while the systematic translation of mhaggrōyē as muhājirūn, though popular among researchers, is still not firmly grounded. In fact, they seem to have had their specific Christological credo, according to the most ancient sources that designate them as such. As his revisionist theory is almost entirely based on a single Greek short excerpt within the very long Byzantine apologetic Doctrina Jacobi, we remark how he never analyzes this single and isolated source with the hypercritical methodology arabicist accept to apply to Arab-Muslim sources. Finally, this skeptical approach needs to be applied – diachronically – for every middle eastern sources, the Muslim as well as the Christian ones, and thus could show many circulations from the first to the second.
Technical and allocative inefficiency in production systems: a vine copula approach
Authors: Zhai Jian , James Robert , Prokhorov Artem
Published: May 2022

Modeling the error terms in stochastic frontier models of production systems requires multivariate distributions with certain characteristics. We argue that canonical vine copulas offer a natural way to model the pairwise dependence between the two main error types that arise in production systems with multiple inputs. We introduce a vine copula construction that permits dependence between the magnitude (but not the sign) of the errors. By using a recently proposed family of copulas, we show how to construct a simulated likelihood based on C-vines. We discuss issues that arise in the estimation of such models and outline why such models better reflect the dependencies that arise in practice. Monte Carlo simulations and a classic empirical application to electricity generation plants illustrate the utility of the proposed approach.
Interesse als Kategorie zur Erforschung frühneuzeitlicher Außenbeziehungen. Überlegungen am Beispiel der Westfälischen Friedensverhandlungen
Authors: Oetzel Lena
Published: May 2022

Seit dem 17. Jahrhundert gilt Interesse als „Schlüsselkategorie“ der politischen Sprache (Herfried Münkler). Auch heute ist der Begriff in unterschiedlichen wissenschaftlichen Disziplinen präsent: in den Internationalen Beziehungen, den Politikwissenschaften, der Soziologie, den Wirtschaftswissenschaften, der Anthropologie oder den Geschichtswissenschaften. Häufig erscheint Interesse dabei als wertneutrale, feststehende und vielfältig einsetzbare Kategorie. Dabei beschreibt es zunächst ein relationales Verhältnis zwischen Akteur und Bezugsobjekt. Was als Interesse definiert wird, unterliegt gesellschaftlichen Normen und Werten und damit dem Wandel.

Dieser Beitrag untersucht diesen prominenten, aber oft unscharf bleibenden Terminus, indem er zunächst einen Überblick über seinen Stellenwert in verschiedenen modernen Wissenschaftsdisziplinen gibt, um dann den frühneuzeitlichen Gebrauch im politik-theoretischen Diskurs und in der diplomatischen Praxis zu betrachten. Als Fallstudie dient die diplomatische Kommunikation auf dem Westfälischen Friedenskongress.

Die zeitgenössische Verwendung des Begriffs im diplomatischen Kontext zeigt, dass Interesse (1) der Beschreibung menschlichen Verhaltens und (2) der Verortung der eigenen Position sowie der von Dritten zueinander diente. Als Element politischer Sprache erfüllte Interesse eine integrative bzw. exkludierende Funktion. In diesem Sinne kann ein kulturgeschichtlich-fundierter Ansatz den beschreibenden Charakter des Begriffs aufgreifen. Interesse ist somit eine beschreibende, relationale Kategorie, die helfen kann, Akteurs-Bezugsobjekt-Konstellationen zu analysieren – im 17. wie im 21. Jahrhundert.
Effect of magnetization of saline irrigation water of Almasab Alam on some physical properties of soil
Authors: Kadhim Kadhim N. , Alghazali Najm O.
Published: May 2022

The effect of magnetization of saline irrigation water from Almasab Alam on some soil physical properties was investigated in this study. The soil was taken from the study site and placed in pots that were identical in all aspects and planted with onion plants in three replications for each case, with the average results taken. The only difference is the quality of the water used in irrigation, which was tested in seven different ways, including irrigating with Almasab Alam drainage salty water without magnetization (NMW), irrigating with river water (CW) from the Mashroa Almusyyab Al-Kabeer river, and irrigating with magnetized Almasab Alam water with five different magnetic intensities (1,000, 2,000, 3,000, 5,000, and 7,000  gauss). When magnetized water with a strength of 3,000 gauss is used, the highest decrease in the bulk density of the soil is 27.30%, and the highest increase in the porosity and permeability of the soil is 64.52 and 651.54%, respectively. Using magnetic technology has made saline Almasab Alam water and drainage water suitable for irrigating crops and also overcome the study area’s water scarcity. Using the magnetic technique of irrigation water also improved the physical properties of the soil, including density, porosity, and permeability, in the study area by washing or planting it with crops.
Husking and mechanical properties of ISAF N231/SAF N110 carbon black filled XNBR-ENR blend rubber compound for rice husk removal applications
Authors: Paramasivam Prabhakaran , Rathanasamy Rajasekar , Ranganathan Rajesh , Palaniappan Sathish Kumar , Pal Samir Kumar
Published: May 2022

White rice kernels are produced in the rice milling process with the help of rubber rollers. Husks are removed from paddy due to friction between the surface of rubber rollers and the paddy layer when the paddy passes between the two rubber rollers [1, 2, 3, 4, 5, 6]. Improved physico-mechanical properties of rubber compounds are needed for husk removal. Based on this review, it was found that small scale rice processing mills in Tamil Nadu, India face the problem of the poor service life of rubber rollers. Rubber compounds with a greater hardness are better for husking rice but breakage in the rice is high. Rice breakage can be minimized when soft rubber is used but the wear rate for soft rubber is high [6, 7, 8, 9, 10, 11, 12]. This study discusses the production of new rubber compounds produced by substituting the proportions of carboxylated nitrile butadiene rubber (XNBR) and epoxidized natural rubber (ENR) with two different carbon blacks. Physico-mechanical properties and lab scale rice-husk separation studies are conducted for these rubber compounds developed. The conclusion is that XNBR- ENR blends with ISAF N231 variety of carbon black prove to be suitable materials for husk removal applications.
Die Navigation im Gesundheitssystem erleichtern – erste Daten zur navigationalen Gesundheitskompetenz
Authors: Griese Lennert , Schaeffer Doris
Published: May 2022

Die Orientierung im Gesundheitssystem erfordert ausreichende navigationale Gesundheitskompetenz. Die Ergebnisse der HLS-GER 2 Studie zeigen jedoch, dass die navigationale Gesundheitskompetenz bei einem Großteil der Bevölkerung in Deutschland gering ausgeprägt ist. Dies trifft insbesondere auf ohnehin benachteiligte Bevölkerungsgruppen zu. Daher ist es wichtig, neben der Förderung der generellen Gesundhitskompetenz auch der Stärkung der navigationalen Gesundheitskompetenz intensivere Beachtung zu schenken und auf allen Ebenen des Gesundheitssystems die dazu nötigen Voraussetzungen zu schaffen.
Remimazolam induced cognitive dysfunction in mice via glutamate excitotoxicity
Authors: Zhou Xin-hua , Zhang Cheng-cheng , Wang Ling , Jin Shan-liang
Published: May 2022

Objective

Several lines of evidence demonstrated the role of anesthetic drugs in cognitive functions. Some anesthetic agents have been confirmed to be associated with long-term spatial memory and learning in aged animal models.

Methods

C57BL/6 mice were divided into four different groups based on different concentrations of remimazolam treatments. Behavioral phenotype was observed by open field, rota rod, Morris water maze, and elevated plus maze test. Western blot was performed to see the expression pattern of different proteins. Confocal microscopy images were taken for neuronal and glial cells to see the effect of remimazolam on CNS cells.

Results

We showed that remimazolam, a new anesthetic drug, impaired cognitive behavior. Repetitive doses of remimazolam have been found to induce neuronal loss with a significant change in morphology. Here, we showed that a higher concentration of remimazolam had a significant effect on CNS cell activation. We showed that remimazolam caused memory dysfunction by inducing neuronal apoptosis via glutamate excitotoxicity. It also exhibited amyloid β plaque in the brain via abnormal phosphorylation of tau protein. Remimazolam-mediated regulation of glial cells in mouse cortex was observed and robust activation of astrocytes and microglial cells was found. Finally, we assessed the behavioral phenotype of mice and found that treatment with remimazolam induced significant behavioral changes and memory dysfunction.

Conclusions

This study provides insight into the mechanism of anesthetic drug-induced memory deficits and may help improve the therapeutic effects of anesthesia agents in clinical applications.

Briceño-Torres, JM, Carpio-Rivera, E, Solera-Herrera, A, Forsse, J, Grandjean, PW, and Moncada-Jiménez, J. Low-intensity resistance training improves flow-mediated dilation in young hispanic adults. J Strength Cond Res 37(2): 298–304, 2023—The purpose of this study was to compare the effects of 2 resistance exercise training (RET) intensities on brachial artery flow-mediated dilatation (FMD) in sedentary males. Thirty-four men (age = 20.6 ± 1.8 years, height = 171.3 ± 5.2 cm, body mass = 65.2 ± 10.6 kg, and DXA fat mass = 22.3 ± 7.4%) were randomly assigned to a control group (no exercise CTRL, n = 12), RET at 50% of 1 repetition maximum (1RM) (RET50%, n = 12), and RET at 80% 1RM (RET80%, n = 10). The RET program was performed twice per week for 8 weeks; subjects performed the same RET exercises at similar total workloads (1920 arbitrary units [AUs] for the RET80% and 1950 AUs for the RET50%). The FMD% was measured before and after 8 weeks by ultrasound. Mixed factorial analysis of variance (3 groups × 2 measurements), effect size (ES), and 95% confidence intervals (95% CIs) were computed for FMD%. The level of significance was set at p ≤ 0.05. A significant increase (p = 0.001) was found on post-test FMD% in RET50% (mean = 9.9 ± 3.7%, ES = 1.9, and 95% CIs = 2.8–0.9) compared with CTRL (mean = 5.7 ± 1.7%, ES = 0.2, and 95% CIs = −0.4 to 0.8), and there were no significant differences found between RET50% and RET80% and between RET80% and CTRL. Results support the concept of training specificity and provide preliminary evidence that lower resistance and higher repetition RET elicit greater short-term reduced endothelium dysfunction than higher intensity RET at similar training volume.
Ad libitum feeding alters mRNA abundance in the ovarian cortex of broiler breeder hens
Authors: Anthony Kate , Garner Tyler Bruce , Ramachandran Ramesh , Diaz Francisco Javier
Published: May 2022

Ad libitum

feeding in broiler breeder (BB) hens causes reduced egg production, lower fertility, and improper eggshell deposition. Restricted feeding (RF) is the only effective intervention available to normalize ovarian function and improve reproductive efficiency. This study aimed to assess the transcriptional changes in ovarian cortex of BB hens with free access to feed compared to those on a RF diet. RNA was isolated from the ovarian cortex of Cobb 500 pullets raised to 10 and 16 weeks of age on either a full-feeding (FF) or RF diet. Microarray analysis identified 386 differentially expressed genes between the two feeding groups at 16 weeks of age. Gene ontology enrichment identified overrepresentation of Neuroactive ligand–receptor interaction pathways, Cell adhesion molecules, Steroid hormone biosynthesis, and various KEGG pathways. From these groups, 46 genes were selected for follow-up validation by quantitative
PCR. The findings show that 33 of the 46 genes had significantly different abundance by age and/or feeding level. Most of these genes were repressed in RF hens and belonged to the steroid biosynthesis and neuropeptide signaling groups. The VIPR2 receptor was higher in the FF group leading us to hypothesize that vasoactive intestinal peptide (VIP) is an important regulator of small cortical follicles. Culture of hen cortical follicles with VIP increased Star, an indication of increased steroidogenic activity, although did not elevate Cyp11a1. These results offer insights and suggest the possible mechanisms and pathways responsible for the increases in cortical follicle growth associated with excess feed intake in BB hens.

Lay summary

Giving breeder hens unrestricted access to feed can lead to problems with their ovaries, including excessive growth of the ovary and reduced fertility. Giving a limited amount of feed is the only effective way to reduce this growth of the ovaries and improve fertility. This study aimed to assess the changes in the molecules that make proteins in the body in hens fed unrestricted and restricted diets. In the hens fed a limited amount of feed, there were more of one type of molecules, while there were more of another type in the ovaries of hens with unrestricted access to feed. These results show that how much a hen eats can alter the number of these molecules in the ovary and this could help us understand why their ovaries grow excessively and why their eggs are less fertile.

La Facultad de Ingeniería Mecatrónica de la Universidad Santo Tomás, seccional Bucaramanga, inició en el año 2005 el proceso de formulación y desarrollo de un trabajo cuya idea se originó por parte de la Clínica Materno Infantil San Luis en Bucaramanga; la cual consistió en la posibilidad de construir un equipo que permitiera aplicar hipotermia cerebral en neonatos, con el fin de prevenir las complicaciones derivadas de la Encefalopatía Hipóxico Isquémica (EHI), que es una de las principales causas de enfermedades neurológicas en neonatos. El presente trabajo describe la forma en que se diseñó y construyó el prototipo inicial de una máquina que, a través de un sistema de enfriamiento de estado sólido basado en células Peltier, produce hipotermia a nivel cerebral en neonatos. Se describe de igual forma el desarrollo de un segundo prototipo a partir de las mejoras realizadas al primero en diferentes aspectos de su estructura. El segundo prototipo obtenido es una máquina que permite aplicar una adecuada temperatura de enfriamiento en el cerebro de los neonatos de manera estable y por el tiempo que especifiquen los especialistas médicos.

Published: May 2022

Chest pain is one of the most common presenting symptoms in patients seeking care from a physician. Risk assessment tools and scores have facilitated prompt diagnosis and optimal management in these patients; however, it is unclear as to whether a standardised approach can adequately triage chest pain in cancer patients and survivors. This is of concern because cancer patients are often at an increased risk of cardiovascular mortality and morbidity given the shared risk factors between cancer and cardiovascular disease, compounded by the fact that certain anti-cancer therapies are associated with an increased risk of cardiovascular events that can persist for weeks and even years after treatment. This article describes the underlying mechanisms of the most common causes of chest pain in cancer patients with an emphasis on how their management may differ to that of non-cancer patients with chest pain. It will also highlight the role of the cardio-oncology team, who can aid in identifying cancer therapy-related cardiovascular side-effects and provide optimal multidisciplinary care for these patients.

Published: May 2022

The aim of this study was to compare the usefulness of thermographic examination of calves with septic arthritis with other diagnostic techniques such as synovial fluid analysis, radiography, ultrasonography and arthroscopy. Thirteen affected joints from eleven calves were used for the trial. The noninfected joints of the trial calves were used as negative controls. Thermography findings showed that heat from 100% of the affected joints was significantly increased. Subchondral osteolysis and new periosteal bone proliferation of articular bones and widening of the intra-articular joint spaces was observed in 10 joints (76.9%) using radiography. Ultrasound examination of all affected joints showed increased effusion with moderate homogeneous echoic structure. Arthroscopic examination showed synovitis and erosion of cartilage in 61.5% and osteophytic formation in 30.7% of affected joints. All diagnostic methods could be used to diagnose joint disease but it was found that thermographic examination in calves with septic arthritis is an easy convenient method to make an earlier diagnosis, which improves treatment success rates.

Due to extreme meteorological and soil hydrological situations the agricultural production security is highly unpredictable. To release the extent and duration of inland excess water (IEW) inundations or two-phase soil conditions during the period intended for cultivation, subsurface drainage (SD) has been used as a best practice in several countries. SD interventions took place between 1960’s and 1990 in Hungary. After 1989, land ownership conditions changed, thus professional operation and the necessary maintenance of the SD networks designed as a complex system became insignificant. In this paper, our aim was to present the IEW hazard in one of the most equipped areas by SD in Hungary. The occurrence frequency of IEW inundations in drained and non-drained (control) areas in different time intervals were compared. According to our results, we could state that the frequency of IEW on the subsurface drained areas was moderately lower in only a few periods compared to the control areas. IEW hazard of the arable areas at the Körös Interfluve was classified as nonhazarded in 52.7% of the area. Another 38.2% were moderately hazarded, 8.26% of the lands were meanly hazarded and less than 1% were highly hazarded area by IEW.

This study explores the effect of leverage, tax planning and firm size on stock returns with investment risk as a moderating variable. The research method used is causal quantitative. The population in this study is the consumption industry sector companies indexed on the Indonesia Stock Exchange for the period 2015 to 2019. The sampling technique using the purpose sampling method obtained 100 samples. The data analysis of this study used a partial least squares structural equation modeling (PLS-SEM) approach with Smart PLS 3.3. The results showed that leverage, tax planning and firm size had no significant effect on stock returns. Investment risk is not able to moderate the effect of leverage, tax planning and firm size on stock returns.
Fake news and the seven sins of capital: a metaphorical analysis of vices in the context of the COVID-19 pandemic
Authors: Vasconcellos-Silva Paulo R. , Castiel Luis David
Published: May 2022

Health crises spawn “sins” and moral deformities in society that are evident when they emerge but had seemed to be dormant to collective awareness before. Through the metaphor of the seven capital sins, the article analyzes the phenomenon of fake news in the social media and in the scenario of the COVID-19 pandemic: the lust of sensationalism through the seduction and exploitation of vulnerabilities associated with fear of death; gluttony for confirmatory contents that spread untruths in the attempt to turn versions into facts; the catechism of denialism, fueling wrath or hate in restrictive epistemic environments; the greed of new technologies in the attention economy through engagement as a new commodity; competition for the spotlights of media visibility and derived gains that incite pride and envy in researchers that confuse public meaning with fake research, in a cycle that feeds sensationalism, gluttony, hate, and greed in attention capitalism. Finally, sloth is portrayed as the capital sin of opting for communicative inaction. In the comfort of bubbles, people renounce dialogue out of aversion to dissent, settling for positions of epistemic comfort. In short, the fake news phenomenon in the COVID-19 pandemic is portrayed here as the convergence of various vices that materialize as misinformation, in the communicative vacuity of the moments in which we are obliged to address each other to share our worldviews.
Impacts of the 2017 Brazilian National Primary Care Policy on public primary health care in Rio de Janeiro, Brazil
Authors: Garcia Fabricio Loureiro , Socal Mariana
Published: May 2022

In 2017, in a scenario of financial restrictions caused by an economic crisis in Brazil, a new primary health care policy promoted changes in the way different primary health care models were prioritized and implemented, with possible negative effects on the access to primary health care. This study aims to investigate if the 2017 Brazilian National Primary Care Policy (PNAB) negatively affected the primary care organization based on the Family Health Strategy (FHS) model and on the access to public primary care services in the city of Rio de Janeiro. The annual averages and the pre- and post-2017 averages of 15 variables were analyzed to identify possible trend breaks in 2017. A Bayesian structural time series model was used to determine the differences between actual and predicted post-2017 averages of each variable. The data were obtained via the Brazilian Health Informatics Department (DATASUS), the Department of Informatics of the Brazilian Unified National Health System. The annual average of family health teams was 1,179.9 teams, in 2017, and 788.8 teams in 2020, while the annual average of equivalent family health teams was 163.6, in 2017, and 125.4, in 2020. The actual post-2017 average of 989.3 family health teams (p = 0.004) was 16.7% lower than the predicted post-2017 average of 1,187.4 teams. In total, 62.6% and 40.5% of the population in Rio de Janeiro were covered by the FHS in 2017, and 2020, respectively. The provision of public primary care services decreased after 2017. Results show a deterioration of the FHS in Rio de Janeiro after 2017 and no increase in the traditional primary care model. Access to public primary care services reduced in the same period.
As fake news e os sete pecados do capital: uma análise metafórica de vícios no contexto pandêmico da COVID-19
Authors: Vasconcellos-Silva Paulo R. , Castiel Luis David
Published: May 2022

As crises sanitárias fazem surgir “pecados” e deformidades morais da sociedade que, embora evidentes quando despontam, pareciam antes dormentes à percepção coletiva. Por meio da metáfora dos sete pecados capitais, o texto analisa o fenômeno das fake news nas mídias sociais e no cenário da pandemia da COVID-19. A luxúria do sensacionalismo, que é viciosa pela sedução e exploração de vulnerabilidades ligadas ao medo da morte; a gula, por conteúdos de confirmação que disseminam inverdades no empenho de converter versões em fatos; a catequese do negacionismo gerando o ódio em ambientes epistêmicos restritivos; a ganância das novas tecnologias da economia da atenção pelo engajamento como nova commodity; a competição pelos holofotes da visibilidade midiática e ganhos derivados que incitam a soberba e a inveja dos pesquisadores que confundem o senso público com as fake researches - o que, em ciclo, nutrirão o sensacionalismo, gula, ódios e as ganâncias do capitalismo da atenção. Por fim, a preguiça é retratada como o vício capital dos que optam pela inação comunicativa. No conforto das bolhas renunciam ao diálogo por aversão ao dissenso, acomodando-se em posições de conforto epistêmico. Em síntese, o fenômeno das fake news na pandemia da COVID-19 é aqui retratado como a confluência de diversos vícios que se materializam como desinformação, na vacuidade comunicativa dos momentos nos quais somos obrigados a nos dirigir uns aos outros para partilhar nossas visões do mundo.
