Challenges for Pastoral Care in Times of COVID-19
Authors: Haußmann Annette D. , Fritz Birthe
Published: April 2022

During the COVID-19 pandemic, challenges have arisen in pastoral care as a result of physical distancing and an increase in social and mental distress. Daily burdens and their consequences have led to an increased need for pastoral support in various fields, for example, hospitals, schools and church congregations. The study analyzes n = 307 pastoral carers in Germany in spring 2020 at the end of the first lockdown. Encounters and media use, interprofessional cooperation, topics of communication and the needs of pastoral carers were assessed for different areas of pastoral care. Results show a drastic decline in face-to-face communication, with significant differences between the various fields of pastoral care. The use of media has increased significantly, with a preference for synchronous interaction via telephone and video. Topics of pastoral care varied from everyday hassles to existential concerns, also including spiritual needs and struggles. Social isolation, the need to just talk to someone and the need for comfort and hope were mentioned the most. During the pandemic, pastoral carers used various media and established new ways to enable encounters and maintain contact. In the future, new methods for enabling pastoral care must be developed, evaluated and reflected on.
Can the Media Prevent Economic Crises by Alerting of their Risk? A Debate on the Limited Effects of the Watchdog
Authors: Rios-Rodríguez Raul , Dios-Vicente Adrián , López-Iglesias Edelmiro
Published: April 2022

Research on coverage of the economic developments in the run-up to the 2008 crisis concludes that the media did not warn of the risks involved, failing in their watchdog role by not anticipating the crisis. However, a key issue remains unaddressed: what would have happened if the media had warned about the factors of instability that led to the crisis? This article explores some answers to this question, for the 2008 crisis and for economic crises in general. To do this, we perform a joint critical review of the literature on watchdog journalism, on economic crises theories, and on media effects on the economy. More specifically, we consider the media’s influence on financial markets, on macroeconomic dynamics (via conditioning the households’ and firms’ behavior), and on economic policy; discussing, at the theoretical level and supported by the empirical evidence available, the ways each kind of media influence could (or not) prevent a structural economic crisis. If the crisis is interpreted as the consequence of dysfunctions in the economic model, or specific errors by agents, it is logical to think that the media could have helped prevent it, by warning of the dangers and promoting changes in public policies and investment decisions. If, on the other hand, the crisis is understood as a necessary readjustment of capitalism in the face of an exhausted accumulation model, the media’s influence would have been very limited in terms of preventing it.
State disinformation: emotions at the service of the cause
Authors: Manfredi Juan-Luis , Amado Adriana , Gómez-Iniesta Pablo
Published: April 2022

Disinformation is not only a phenomenon of modern democratic societies, but also a tool at the service of states. In the current communication ecosystem, politics and society interrelate in the face of a phenomenon characterised by multiple information channels and sources in which emotions now play a central role. In international relations, the expression of a state’s political will through charisma and populism are the chief aspects detected in the analysis of emotions in political science. This has led to the construction of a narrative based on security threats and the friend-enemy distinction, among other things. On the basis of an exhaustive literature review, this study offers an overview of the political and social factors underlying the use of emotions in disinformation as regards four aspects: politics, economy, diplomacy and security. Likewise, it identifies the main defining traits and behaviours of domestic and international audiences. The analysis and verification of the research question contribute to elaborate an international theory of emotionally driven disinformation which has begun to play a leading role in both academia and politics.
Research on News Sharing. A Proposal of bibliometric analysis
Authors: Quevedo-Redondo Raquel , Antona-Jimeno Tamara , Vicent-Ibáñez Mireya
Published: April 2022

This study seeks to establish whether news sharing in social media is a mature field of research by using bibliometrics as a tool. The Web of Science database was searched for articles that contained the term ‘news sharing’ in titles, keywords, and abstracts. A total of 133 articles was obtained, which enabled us to address the question of whether there are well-established journals and authors that cover the subject. The results show a certain ambiguity, which could explain why the chosen subject matter is often studied in fields outside of Communication Studies; however, while studies on news sharing are conducted by researchers from heterogeneous fields, this has not translated into greater interdisciplinarity.
The difficulties in spreading housing rights discourse in the face of ‘right now’ pragmatism on Twitter
Authors: Ramon-Pinat Ezequiel
Published: April 2022

Social movements work in various overlapping dynamics: in the short term, trying to mobilize the largest number of sympathizers in their actions and in the long term, in a battle to change meanings and cognitive frameworks in a society. This article investigates how the Platform for Those Affected by Mortgages (PAH) uses Twitter in the two spheres above mentioned. The literature referring to collective mobilization explains activism in two complementary logics. A first one, rational, where participants only think about a concrete benefit, and a second, focusing on challenging established beliefs. As complex societies, the media and, more recently, social networks have gained in importance as a space where the legitimacy of these claims are discussed. In this analysis, frame theory has been applied to tweets referring to evictions published at the official account @LA_PAH. Twitter, unlike other social networks, allows quick mobilization to gather activists and stop evictions, a valuable and positive asset. However, it ends up giving a limited image, focused on avoiding evictions, instead of a message to establish housing access as a good that must be guaranteed, outside the market. The extreme cases, those about families including children and elderly, predominate in the posts. This visibility certainly generates empathy but leads to the false feeling that only the most vulnerable citizens are affected.
Brand strategy and content management on Instagram: scheduling and message length as factors to improve engagement
Authors: Cuevas-Molano Elena , Sánchez-Cid Manuel , Gordo-Molina Virginia
Published: April 2022

Companies use social media in their communication strategy to connect with their audiences via online brand communities and social media fan pages. In this context, the scientific community defines the term ‘engagement’ as the primary metric used to identify the degree to which brand and consumers are organically connected. This phenomenon gets measured by audience interactions with the brand content, which is the main factor stimulating participation and value perception in their relationship with the brand. Prior investigations show that the timing and duration of the messages published by the brand can predict the degree of social media engagement, however they do not provide the time and length patterns required for messages to increase engagement. For this purpose, we carried out a quantitative and descriptive content analysis of 14,067 Instagram posts from 14 Spanish brands across 10 industries. Findings allow us to conclude that brands are not fully optimising the scheduling of their timings during the working days and hours that drive the best level of interaction. Nonetheless, they do take advantage of the opportunity to publish longer messages to increase engagement. From a theorical and practical point of view, this analysis contributes to the understanding of the content factors that stimulate fan page engagement and provides guidelines for brand managers to efficiently define the content marketing strategy on Instagram.

The environmental quality of 6 famous sand beaches of the Ha Long - Cat Ba area was surveyed in July 2018 (the rainy season) and March 2019 (the dry season). The results showed that the pore water layer below the sand surface contained some pollutants exceeding the critical value of QCVN 10:2015/BTNMT for coastal water and ASEAN-criteria, including TSS, ammonium and nitrate. In the rainy season, the pore water quality was lower than that in the dry season, indicating that the tourism influenced the sandy beach water quality. Among the studied beaches, Ha Long and Bai Dai (Van Don) showed pore water pollution; the rest beaches were low to moderate pollution. Pore water in sandy beaches was charecterized by low dissolved oxygen saturation and high mineralization compared to sea water, thus confirming the role of sandy beaches in providing mineral nutrients to the sea. Analysis of the sediment grain size at the sandy beaches showed that the beach quality was medium to good. Forty-seven benthic fauna species were found on sandy beaches of the Ha Long - Cat Ba area, of which the dominant species were mollusks, followed by crustaceans, polychaetes, and echinoderms. The biodiversity of sandy beaches in study area was at an average level.

Vietnam was the fifth country that dumped more plastic into the oceans than the rest of the world combined. The country produces an average of 25.5 million tons of waste per year, of which 75% is buried. Several burial sites in major cities such as Hanoi, Ho Chi Minh city, and Da Nang city are overloaded and negatively affecting citizens’ lives. Therefore, sorting at source would significantly reduce soil resources and groundwater pollution and save money on collection costs, transportation, treatment, and easing the pressure on the landfills. Using computer vision may help classify easily recyclable trash into different categories based on its material. This paper proposes an experiment on a customed Convolution Neural Network (CNN) based waste detector for three classes of trash: Plastic bottles, Cans, and Glass. The study used up to 900 hand-collected image data separated into 500 for analysis and 400 remains for assessing the result. All trashed objects used for generating data were collected around the Ho Chi Minh city University of Technology (HCMUT, Vietnam). The Deep Learning model used in this research, named SSD MobileNet V2, is part of the open-source Tensorflow Object Detection API. The system gave the result, the relative match percentage of different amounts of data we fed the model. The system showed linear relativity between the amount of data trained AI100, AI200, AI300, AI400, AI500, and the mean Average Precision (mAP) when testing the system. From this on, the study conducted another experiment to ensure that the performance of the trained model would meet expectations, AI401. In this experiment, the system showed over 80% inaccuracy overall. By back-analysis, this paper would be a good vision for researchers to study and enhance the system’s accuracy to serve the purpose of trash classification in innovative trash bin applications.
Research results of biological resources and and biodiversity of Vietnam sea: current status, treats, proposed solutions to use lasting
Authors: Do Cong Thung
Published: April 2022

The marine biology investigation and research activities in our country since 1990 have made remarkable changes; especially there have been changes in thinking, scale, content, level, research, skills research, and international relations in research. We have proactively overcome the limitation of general, preliminary, and undirected investigation to shift to new thinking about research gradually. Research on changes in typical ecosystems is extended to the whole sea, to deep water, offshore and remote islands such as Pracel (Hoang Sa) and Spratly (Truong Sa). We have focused on researching issues about the causes of formation, the law of fluctuations, and the mechanism of action of marine processes, studying the basis of the application of technology, and creating new technologies to solve these problems in practice. Therefore, there have been outstanding results compared to the period before 1990. It has been identified that there is a high level of biodiversity in the sea of Vietnam with over 11,000 species, forecast to reach 12,000 marine species, and 134 species are listed in the Red Book of Vietnam, but the structure of biodiversity and marine resources in our country are also susceptible and vulnerable. Also, nearly 20 specific ecological systems and sub-systems have been identified in the sea and coastal areas; Seafood reserves of almost 4 million tons are an essential basis for developing eco-tourism, fishing, and aquaculture. Due to economic and social activities, many threats to marine biodiversity have been caused: narrowing of ecosystem area, decrease in density, number of species and reserves, decrease in ecosystem value, and habitat degradation. The real solutions to conserve and sustainably use biodiversity and marine resources include institutional and policy solutions, strengthening the construction of protected areas, artificial reefs, and areas where exploitation is prohibited over time, sustainable exploitation and cultivation of marine resources, and sustainable marine economic development.

Samples of soft coral Sinularia flexibilis were collected for one year, from January to December, in the Nha Trang coastal area, Khanh Hoa province, to assess the month-by-month fluctuation of total lipid content and lipid classes composition in this species. Full lipid content reached the highest value from March to May, lower in the period of June-September, and bottomed in October and November. There was a significant decrease in this content between May and June, September and October; the content increased from February to March but was not stable from October to February. The lipid classes composition of Sinularia flexibilis includes polar lipids (PL), sterols (ST), triacylglycerol (TAG), monoalkyldiacyl-glycerol (MADAG), wax (W), and free fatty acids (FFA). The concentration of PL in summer (April-August) was lower than that in winter (September-February); this content increased significantly during November-December; meanwhile, it was observed to decrease in April-May, December-January. The content of ST increased from October to March and declined from April to September. The remaining classes, including W, MADAG, and TAG, tend to grow in the summer and decline in the other months. The fluctuation of lipid class composition throughout the year is closely related to zooxanthellae microalgae in corals at different times of the year and is directly influenced by environmental conditions, especially seawater temperature. Besides, this coral’s maturation and reproduction effect with the increase or release of reproductive materials was also observed.

DDT (Dichloro-diphenyl-trichloroethane) and chlordane are the organochlorine pesticides (OCPs) dangerous to human health and easily accumulate in biological tissues, used to control insects in crops, livestock and house protection. This study aimed to evaluate the toxicity of DDT, cis (alpha-chlordane), and trans (gamma-chlordane) on the growth of two crustaceans species Daphnia magna (D. magna) and Moina macrocopa (M. macrocopa) after 24 h and 48 h. Each test concentration selected 9 individuals of each species and repeated 4 experimental times, the study results showed that the 50% lethal concentration (LC50) of D. magna and M. macrocopa when exposed to DDT for 24 h were 20.8 μg.L-1 and 13.5 μg.L-1, respectively; after 48 h the value decreased to only 4.8 μg.L-1 and 1.7 μg.L-1. Similarly, LC50 values of cis (alpha-chlordane) on 2 species after 24 h exposure were 12.4 μg.L-1 and 11.8 μg.L-1, respectively; after 48 h were 4.6 μg.L-1 and 4.9 μg.L-1. The calculation results of LC50 when exposed to trans (gamma-chlordane) of D. magna and M. macrocopa after 24 h are 17.6 μg.L-1 and 12.4 μg.L-1, respectively; after 48 h, it decreased to 3.8 μg.L-1 and 3.7 μg.L-1 (p < 0.05). The results of the acute toxicity assessment also indicated that M. macrocopa was more sensitive to toxicity than D. magna with the same test conditions.

Basert på fokusgruppeintervjuer undersøker denne studien hvordan elever opplever møter med rådgivere i ungdomsskoler og videregående skoler. Individualisering danner en sentral kontekst for elevers valgprosesser. Improvisasjon, forstått som rådgiveres varhet for elevenes ønsker og behov og evne til å være til stede i her-og-nå-situasjonen, brukes for å belyse elevenes opplevelser av å møte rådgiveren. Rådgiverens balansekunst mellom informasjon, refleksjon og handlingsorientering ser ut til å være sentral for at eleven skal oppleve et godt møte med rådgiveren. Funnene tyder på at rådgiverens evne til improvisasjon og hennes/hans evne til å se og forstå eleven har betydning for hvordan rådgiveren oppleves. Dette ser ut til å kreve en balanse mellom å oppfatte elevens ønsker og behov og å tilpasse rolleutøvelsen til dette. Studien foreslår at dette kan gjøres gjennom en improvisasjonsbasert rådgivningspraksis. Videre fremkommer det at hvis eleven får anledning til å være medskaper i egne valgprosesser, kan dette bidra til at eleven ønsker videre kontakt med rådgiver.
«Det er en fremmed tanke å skulle ha studentene for seg selv»
Authors: Hvalby Mette , Thortveit Jorunn
Published: April 2022

Praksisveiledning i lærerutdanningene er en oppgave som ofte ivaretas av den enkelte praksislærer, og tidligere forskning viser store variasjoner i veiledningskvalitet, oppfølging og læringsutbytte for studentene. Denne studien omhandler en veiledningspraksis med etablering av veilederteam på en skole der majoriteten av lærerne er kvalifiserte praksislærere. Termen veilederteam viser her til at flere praksislærere tar felles ansvar for oppgavene knyttet til en og samme studentgruppe. Hensikten med studien er å belyse hvordan studenter og praksislærere erfarer denne organiseringen, og hvordan begge gruppene knytter erfaringene til egen læring og utvikling. Studien er en sosiokulturelt forankret casestudie med data basert på intervjuer med tre veilederteam og deres studentgrupper gjennom en praksisperiode. Funnene indikerer en begynnende kollektiv veilederpraksis bygget på en eksisterende samarbeidskultur, støttet av koreograferte læringsmøter som strukturerende ressurs.

Influenza is a severe, vaccine-preventable disease. Vaccination programs across Latin American countries show contrasting coverage rates, from 29% in Paraguay to 89% in Brazil. This study explores how national influenza vaccination programs in the chosen South American countries address vaccine confidence and convenience, as well as complacency toward the disease. Barriers and facilitators to influenza vaccination programs in their relation to vaccine hesitancy were observed by documentary analysis and interviews with 38 national immunization program officers in high- (Brazil and Chile) and low-performing (Paraguay, Peru, and Uruguay) countries. Influenza vaccination policies, financing, purchasing, coordination, and accessibility are considered good or acceptable. National communication strategies focus on vaccine availability during campaigns. In Chile, Paraguay, and Uruguay, anti-vaccine propaganda was mentioned as a problem. Programming and implementation face human resource shortages across most countries. Statistical information, health information systems, and nominal risk-group records are available, with limitations in Peru and Paraguay. Health promotion, supervision, monitoring, and evaluation are perceived as opportunities to address confidence and complacency. Influenza vaccination programs identify and act on most barriers and facilitators affecting influenza vaccine hesitancy via supply-side strategies which mostly address vaccine convenience. Confidence and complacency are insufficiently addressed, except for Uruguay. Programs have the opportunity to develop integral supply and demand-side approaches.

Abstract The study investigated the wound healing effect of medicinal oil (MO) formulation prepared from Murraya koenigii leaves extract (methanolic) incorporated in olive oil. The MO was visually transparent, homogenous, smooth in texture, the viscosity grade was observed as 140 cP and easily spreadable. Pro-inflammatory cytokines IL-1β, IL-6, and TNF-α were significantly reduced to 82.3 ± 3.5, 156 ± 6.2, 137.3. ± 5.5 pg/ml, respectively after treatment with MO when compared to disease control animals that showed IL-1β, IL-6, and TNF-α levels of 170 ± 6, 265 ± 7, and 288.6 ± 11, pg/ml respectively. The level of pro-inflammatory cytokine in povidone iodine solution (PIS) group was 95.3 ± 3, 162 ± 6, 177.6 ± 8.9 pg/ml of IL-1β, IL-6, and TNF-α respectively. Interestingly, the wound-healing efficacy of MO was found better as compared to povidone iodine treated standard group and concluded that MO has excellent wound healing effect.

CLASSIFICAÇÃO E BIODEGRADAÇÃO DE LODO DE ESTAÇÕES DE TRATAMENTO DE ÁGUA PARA DESCARTE EM ATERRO SANITÁRIO
Authors: Guerra R.C. , Angelis D.F.D.
Published: April 2022

RESUMO A produção de água para abastecimento público, realizada pelas Estações de Tratamento de Água (ETAs) é responsável pela geração de resíduos, originados durante a remoção de material solubilizado e partículas em suspensão na água bruta. Geralmente, o destino do lodo acumulado nos decantadores das ETAs é o curso d’água mais próximo, sem que nenhum tratamento seja realizado. O objetivo deste trabalho foi verificar a possibilidade de disposição final, em aterro sanitário, dos sólidos resultantes dos processos de secagem do lodo de duas ETAs: ETA Capim Fino, Município de Piracicaba, SP e ETA II, Município de Rio Claro, SP. Os ensaios para a classificação do lodo de ETA foram realizados de acordo com a norma NBR 10.004 "Resíduos Sólidos – Classificação" da ABNT. Os ensaios de biodegradação foram realizados pelo método respirométrico de Bartha da Cetesb. Os resultados indicam que os lodos estudados são classificados como resíduos não inertes, necessitando de condições adequadas para sua disposição final, entretanto a aplicação de lodo ao solo do aterro sanitário não interferiu de forma negativa no processo de biodegradação, indicando que sob esse aspecto, a co-disposição deste resíduo, juntamente com o solo utilizado na cobertura das células do aterro sanitário do Município de Rio Claro é viável.

Abstract Ilex parguariensis pyrenes, popularly known as “yerba mate”, were classified as dormant. This study aim to investigated the causes of dormancy in Ilex paraguariensis’ pyrenes. Hence, the following tests were performed: a) Physical dormancy: rate of absorption in water and methylene blue; detection of lignin and lipophilic compounds in the endocarp and integument; b) Physiological dormancy: bioassays in lettuce seeds, detection, and quantification of phenolic compounds; c) Morphological dormancy: embryo analysis. For the absorption rate, an increase was observed in the mass of the pyrenes, however, when imbibition was performed in methylene blue, absorption only occurred in the endocarp. Lignin was also observed in the form of a sclerenchyma layer next to the seed coat. Similarly, lipophilic compounds were observed in a layer, external to the endosperm. The bioassays with lettuce seeds indicated the presence of chemical inhibitors. In the morphological evaluation of the pyrenes, only 55.5% of the embryos were visualized and they were in the globular or heart stages. Ilex paraguariensis pyrenes have combined dormancy: physical (not water absorption), morphological (due to the underdeveloped embryo), and there are shreds of evidence about physiological dormancy (presence of inhibitors); however, it is recommended to investigate the inhibitory agent.

ABSTRACT Purpose The aim of this study was to evaluate the contribution of the CROS system on the head shadow effect in unilateral implant users. Methods Prospective cross-sectional study, approved by the ethics committee under protocol 2.128.869. Eleven adults with post-lingual deafness users of unilateral Advanced Bionics CI were selected. Speech recognition was evaluated with recorded words presented at 65dBA at 0o azimuth and at 90o on the side contralateral to the CI, with noise at 55dBA, using CI alone and CI + CROS system. The results were analyzed using paired t-test with a 0.05 alpha. Results The mean speech recognition scores were significantly better with CI + CROS in relation to the condition of CI alone (p <0.05, p <0.005 and p <0.005 respectively). In the presentation at 0o azimuth, no significant differences were found. Conclusion Users of unilateral CI without useful residual hearing for the use of hearing aids or unable to undergo bilateral surgery can benefit from the CROS device for speech recognition, especially when the speech is presented on the side contralateral to the CI.
O Modo Africano de Fazer a Guerra: A Guerra Proxy Irregular Regionalizada
Authors: Silva Igor Castellano da
Published: April 2022

RESUMO As guerras africanas têm sido amplamente descritas como um fenômeno apolítico, doméstico e localmente restrito. Todavia, tais narrativas não se sustentam após análises mais robustas de dados empíricos, mediante o uso de conceitos capazes de equilibrar generalidade teórica e particularidade dos casos. O défice analítico sobre as guerras na África dificulta inclusive a avaliação de suas causas, consequências e do impacto das respostas geralmente adotadas para as suas resoluções. Este artigo argumenta, em oposição a visões correntes, que as guerras existentes no continente e suas notórias complexidades e irregularidades constituem uma tríade securitária, sintetizada no conceito de Guerra Proxy Irregular Regionalizada. As causas e os efeitos sistêmicos desse modo africano de fazer a guerra estão relacionados, além de causas objetivas, a amplas causas permissivas, nomeadamente ao processo de construção do Estado no continente, envolvendo sua interação com as dinâmicas regionais e a penetração extrarregional. Respostas mais efetivas para guerra na África deveriam levar em conta essas características, suas causas e consequências, e considerar o papel de ações mais sustentáveis, tais como reformas autofortalecedoras dos Estados e o envolvimento de iniciativas regionais mais vigorosas.

O presente artigo apresenta a analise de como as práticas de ensino dos docentes de um curso de licenciatura em Ciências Biológicas, de uma Instituição de ensino no norte do País, se relacionam com a concepção de interdisciplinaridade prevista no Projeto Pedagógico do Curso e no Projeto Pedagógico institucional. Caracterizada pela troca de conhecimentos recíprocos entre duas ou mais áreas de conhecimentos, a interdisciplinaridade tem sido considerada indispensável nos currículos para formação de professores. A pesquisa realizada, foi de abordagem qualitativa, com delineamento de estudo de caso. Os participantes foram o Coordenador, docentes, e licenciandos do curso. Para produção de informações, utilizou-se múltiplas técnicas a partir de fontes: documentais; observacional; entrevista semiestruturada e grupo de discussão. A análise do corpus deste estudo foi realizada a luz da Análise Textual Discursiva. Como resultado, observa-se em relação as práticas de ensino, o desenvolvimento das atividades interdisciplinares por meio de um componente curricular, denominado projeto integrador, sendo o ensino baseado em projetos a metodologia mais utilizada pelos docentes. Sobre a concepção curricular, o PPC do curso direciona o ensino interdisciplinar partindo da relação, teoria e prática, por meio da articulação dos conhecimentos específicos e pedagógicos, ficando evidente que as atividades propostas contemplam parcialmente a interdisciplinaridade. Por fim, evidencia-se que mesmo havendo uma convergência de esforços para o desenvolvimento do ensino interdisciplinar, as práticas docentes ainda não conseguem estabelecer uma relação com a concepção de interdisciplinaridade presentes nos documentos Institucionais.

Este estudo tem como objetivo compreender quais as narrativas de gênero presentes na produção científica brasileira nas ciências da saúde no que diz respeito à Educação Física escolar. Trata-se de uma pesquisa exploratória, de abordagem qualitativa. A metodologia utilizada foi a scoping review e foram incluídos nesta pesquisa artigos científicos encontrados na Biblioteca Virtual em Saúde (BVS). Chegou-se a 16 artigos, os quais consistiram na amostra deste estudo e foram lidos na íntegra. Como resultado pode-se afirmar que: as publicações envolvem instituições públicas em sua maioria e, a maior parte deles, aconteceu na década de 2010; o Ensino Fundamental foi o nível educacional mais presente e os/as estudantes tiveram participação importante nessas pesquisas; os trabalhos se mostraram, majoritariamente, qualitativos, sendo a observação e o questionário os instrumentos de coleta mais utilizados. Em relação ao conceito de gênero, a análise evidenciou que todos os trabalhos que tratavam dessas relações entendem gênero como uma construção social e histórica. Nesse sentido, pode-se concluir que a produção científica brasileira no campo das Ciências da Saúde que se debruçou sobre as relações de gênero na educação física escolar esteve delineada pela busca de melhor compreensão de um cenário excludente, sexista, que estimula de maneiras diferentes as vivências corporais de meninos e meninas e que reproduz estereótipos relacionados às feminilidades e masculinidades e assim, ao longo da história, colocou as meninas num plano inferior e desigual na educação básica.
Predicting Decisions in Language Based Persuasion Games
Authors: Apel Reut , Erev Ido , Reichart Roi , Tennenholtz Moshe
Published: April 2022

Sender-receiver interactions, and specifically persuasion games, are widely researched in economic modeling and artificial intelligence, and serve as a solid foundation for powerful applications. However, in the classic persuasion games setting, the messages sent from the expert to the decision-maker are abstract or well-structured application-specific signals rather than natural (human) language messages, although natural language is a very common communication signal in real-world persuasion setups. This paper addresses the use of natural language in persuasion games, exploring its impact on the decisions made by the players and aiming to construct effective models for the prediction of these decisions.

For this purpose, we conduct an online repeated interaction experiment. At each trial of the interaction, an informed expert aims to sell an uninformed decision-maker a vacation in a hotel, by sending her a review that describes the hotel. While the expert is exposed to several scored reviews, the decision-maker observes only the single review sent by the expert, and her payoff in case she chooses to take the hotel is a random draw from the review score distribution available to the expert only. The expert’s payoff, in turn, depends on the number of times the decision-maker chooses the hotel. We also compare the behavioral patterns in this experiment to the equivalent patterns in similar experiments where the communication is based on the numerical values of the reviews rather than the reviews’ text, and observe substantial differences which can be explained through an equilibrium analysis of the game.

We consider a number of modeling approaches for our verbal communication setup, differing from each other in the model type (deep neural network (DNN) vs. linear classifier), the type of features used by the model (textual, behavioral or both) and the source of the textual features (DNN-based vs. hand-crafted). Our results demonstrate that given a prefix of the interaction sequence, our models can predict the future decisions of the decision-maker, particularly when a sequential modeling approach and hand-crafted textual features are applied. Further analysis of the hand-crafted textual features allows us to make initial observations about the aspects of text that drive decision making in our setup.
Strength characteristics of brittle rocks under multi-stage intermediate principal stress loading

Published: April 2022

A series of single-stage true triaxial compression (TTC) tests and multi-stage intermediate principal stress (σ2) loading tests were carried out on three types of brittle rock specimens in this study to examine the influence of σ2 and the validity of obtaining strength parameters by using a multi-stage loading method under true triaxial stress conditions. There exists a critical σ2 at which the rock strength attains its ultimate value under both loading conditions. Under the same σ3 level, the critical σ2 is much smaller under the multi-stage σ2 loading compared with under the single-stage TTC. The test results also show that the strength determined under multi-stage σ2 loading is much smaller than that determined under single-stage TTC. The strength difference can attain 39%. A lower strength is measured under multi-stage σ2 loading because the local fracture plane induced by true triaxial stress is parallel to the σ2, and the strength of the rock specimen containing this type of local fracture plane is not affected by σ2. On the contrary, rock damage accumulates during multiple loading and unloading cycles. The current testing results indicate that the multi-stage loading test is not suitable for determining the strength envelope of brittle rock under true triaxial conditions.
Dynamic and Stochastic Search Equilibrium
Authors: Morales-Jimenez Camilo
Published: April 2022

I study the business cycle properties of wage posting models with random search, for which the distributions of employment and wages play a nontrivial role for the equilibrium path. In fact, the main result of this paper is that the distribution of firms is one of the most important elements to understand business cycle fluctuations in the labor market. The distribution of firms (1) determines which shocks are relevant for the labor market, (2) implies that wage rigidity does not significantly amplify shocks, and (3) puts discipline on the relative value of the flow opportunity cost of employment. To assess these type of models quantitatively, I propose a new algorithm that finds the steady state and computes transitional dynamics rapidly. Hence, integrating wage posting models with random search to larger models becomes possible (and easy) with this new algorithm.

Published: April 2022

Background: Spinal intramedullary cavernous angioma is a rare form of spinal cord tumorthat is associated with myelopathy and significant morbidity and surgical treatment is almostalways required.Case: We report a case of spinal intramedullary cavernous angioma in a pain clinic with initialsymptoms of unilateral interdigital space sensory change. Morton’s neuroma and piriformissyndrome were clinically suspected, however, symptoms acutely aggravated, andparaplegia developed following the patient’s COVID-19 vaccination. Vaccine-associated sideeffects were ruled out and spinal intramedullary cavernous angioma was confirmed throughmagnetic resonance image. The patient underwent surgery for complete mass excision.Conclusions: Recent reports of COVID-19 vaccine-associated side effects have raised sensitiveconcerns to both health care providers and the public, that in some cases when thesymptoms coincide with vaccination history, it may delay time-sensitive diagnosis and treatmentand spend unnecessary costs.
A case study on slope instability of Punatshangchhu Hydroelectric Project Authority-I Dam in Bhutan
Authors: Lhamo Rinchen
Published: April 2022

The stability of the slope is a greater concern to engineers and geoscientists as the socioeconomic consequences of the failures are huge. One such case is the slope instability of right bank of Punatshangchhu Hydroelectric Project Authority (PHPA-I) dam, Bhutan. The main geology of dam site is characterized by coarse-grained quartzo-feldspathic and biotite- muscovite gneiss. Since the start of the project in 2008, project encountered several geotechnical problems. During excavation at dam pit area, the shear zone got day-lighted which triggered a huge movement of right bank of dam in 2013. As such, project authority has carried out various stabilization measures in arresting movement of right abutment of dam. In this paper, subsurface profile construction from boring log data using Rockwork software (Rocscience) for PHPA-I dam site is presented. The subsurface profile once constructed can be used for identifying the critical slip surface and can also be used in modeling for slope stability analysis. Moreover, it can be a database for future use in that part of the study area.
Local procurement in the mining sector: Is Ghana swimming with the tide?
Authors: Atta-Quayson A.
Published: April 2022

Since 2012, Ghana has been implementing local procurement regulations in the mining sector to broaden and deepen linkages between mining and other sectors of the economy. The regulations have been implemented in collaboration with the mining industry. This paper offers an in-depth analysis of how the local procurement regulations and related initiatives have been implemented so far. Primary data gathered with semi-structured interviews and secondary sources of data indicate a steady improvement in both in-country procurement and local manufacturing of inputs for the mining industry. There are, however, some challenges relating to tariff structure and support (financial and technical) for local suppliers and manufacturers to meet high standards and demands of the mining industry. This calls for a well-thought-out strategy and programme of activities to sustain and improve on progress made.
Comparison of capsule-mixed versus hand-mixed glass ionomer cements Part II: Porosity
Authors: Arnold Samantha , Buchanan Glynn D , Warren Nichola , Potgieter N
Published: April 2022

Glass ionomer restorative cements (GIC) are routinely used in dental practice. During mixing, air incorporation may lead to higher porosity with subsequent weakening of the cement. The degree of porosity will determine whether capsule-mixed or hand-mixed GIC are mechanically stronger for clinical use. To compare the porosity of four commercially available dental glass ionomer cements, supplied in both hand mix and capsule-mix formulations, by evaluating number of voids (%), total volume of voids (mm3 ) and volume percentage of voids (%). Eighty samples were manufactured from hand-mixed GIC: Riva Self Cure; Fuji IX GP ; Ketac Universal, Ketac Molar Easymix, and equivalent capsule-mixed GIC: Riva Self Cure; Fuji IX GP ; Ketac Universal Aplicap and Ketac Molar Aplicap. Micro-CT scanning was used to evaluate porosity. The number of voids (mm3 ), total volume of voids (mm3 ) and the volume percentage of voids (%) were calculated.
Immunofluorescence of RAB5 and FLAG-EEA1 puncta after Dynamin-1 and -2 inhibition with Dyngo4a v2
Authors: Park Hankum , V Hundley Frances , JW Harper
Published: April 2022

Selective purification of early endosomes can be achieved through affinity capture of the early endosome-associated protein EEA1 (termed Endo-IP) (Park et al. 2022). These purified endosomes can be used for proteomic and lipidomic studies to obtain snapshots of early endosomes. Here, we present an immunofluorescence protocol to assess the extent of colocalization between FLAG-EEA1 and RAB5 with and without the Dynamin-1 and -2 (DNM1/2) inhibitor Dyngo4a.
Endosomal and lysosomal immunoprecipitation for proteomics, lipidomics, and TEM v2
Authors: Park Hankum , V Hundley Frances , Wade Harper J.
Published: April 2022

Previous studies have developed methods for isolation of lysosomes, mitochondria, and peroxisomes from non-denaturing extracts. Here we describe an approach for purification of early/sorting endosomes, providing a means by which to examine early aspects of the endolysosomal system and to combine this with lysosome purification using Lyso-IP. We refer to this new method as Endo-IP. This allows us to examine the proteome and lipidome of endosomes, and to perform electron microscopy imaging of endosomes.
Measuring pattern separation in hippocampus by in situ hybridization v1
Authors: Eom Kisang
Published: April 2022

Pattern separation is a process that minimizes overlap between neuronal activity patterns those representing similar experiences. The mechanisms of pattern separation have been investigated for several decades. Theoretical models suggest that dentate gyrus (DG) segregates cortical input patterns before relaying its discriminated output patterns to CA3. So evaluation of neural ensembles in DG and CA3 have an important part for investigation of pattern separation. Measuring of entorhinal cortex (EC), DG and CA3 ensembles were largely depended upon the electrophysiological recordings, which is technically difficult. We present that more simple and convenient method for measuring pattern separation based on molecular method in this article.
