Elecciones de Brasil en 2014: las webs de los candidatos presidenciales como herramienta de campaña electoral
Authors: Massuchin Michele Goulart , Campos-Domínguez Eva
Published: August 2022

Este artículo analiza el uso de Internet como espacio de campaña en Brasil, atendiendo al último periodo electoral de 2014. Toma como objeto de estudio las páginas webs de los tres principales candidatos a la presidencia: Dilma Rousseff (PT), Aécio Neves (PSDB) y Marina Silva (PSB). Este eje de investigación sigue la línea de estudios realizados dentro y fuera de España, con una amplia tradición académica, que analiza la estructura y principales características de las webs políticas. La propuesta desarrollada aquí actualiza esta metodología para aplicarla al caso brasileño más reciente y estudiar, de manera comparada, el desarrollo de los sitios web de los tres principales candidatos de Brasil, basándose en un análisis cuantitativo y semi-cualitativo de estos sitios web. El estudio tiene como punto de partida la discusión teórica sobre la modernización de las campañas electorales: desde los avances y las nuevas posibilidades añadidas, las páginas han avanzado en su desarrollo en términos estructurales, ofrecen nuevas características de interacción y más opciones de información política, avanzando, así, hacia la transparencia y participación. Los resultados obtenidos en este análisis indican que, en algunas dimensiones, las páginas presentan avances significativos — como por ejemplo, la actualización diaria — mientras que, en otras, mantienen, todavía, fórmulas básicas propias de la web 1.0.
O estado de arte da Comunicação Organizacional: as tendências do século XXI
Authors: Silva Sónia , Ruão Teresa , Gonçalves Gisela
Published: August 2022

A comunicação no contexto das organizações está em constante reconfiguração. As novas formas de informação, de interação, de partilha e de consumo que caracterizam as sociedades atuais trazem novos desafios às organizações e às suas estruturas comunicativas e tal justifica, sempre que possível, uma incursão pelo campo da Comunicação Organizacional com a principal motivação de compreender o estado atual da disciplina e acompanhar as suas tendências de investigação.

Tal é o propósito deste estudo: averiguar o estado da arte da Comunicação Organizacional recuando, para isso, às origens da disciplina e às suas preocupações fundacionais, as quais são fundamentais para compreender as abordagens que descrevem o campo no século XXI. Com esta análise pretendemos traçar as tendências de investigação da disciplina a abordar os principais desafios que caracterizam a relação entre comunicação e organização na atualidade.

Para cumprir este objetivo, recorremos a uma metodologia qualitativa, através da análise de vários artigos científicos e de livros publicados no âmbito dos estudos da Comunicação Organizacional (desde o aparecimento da disciplina), os quais nos permitiram entender e descrever as abordagens, os paradigmas, as metodologias, os temas e as tendências que protagonizaram a criação e o avanço desta disciplina. Trata-se, portanto, de uma revisão da literatura que privilegiou os trabalhos de académicos e investigadores reconhecidos nesta área científica. A sua análise foi fundamental para descrever os quatro paradigmas que se desenvolveram campo da Comunicação Organizacional: o positivista, o interpretativo, o crítico e o constitutivo.

Percebemos, como conclusão, que estas abordagens convivem harmoniosamente na tentativa de explicar o ambiente organizacional atual, o qual parece ter como principais desafios a constante evolução das tecnologias de informação e comunicação, que atribuem mais poder aos públicos e enfatizam os processos de comunicação relacional e a importância de comportamentos organizacionais éticos e responsáveis no seio de uma sociedade cada vez mais exigente e informada. Assim, também a comunicação enquanto estratégia tem conquistado espaço nas tendências de investigação em Comunicação Organizacional, como um tipo de comunicação que procura apoiar a missão da organização ao mesmo tempo que procura estabelecer relações profícuas entre a organização e os seus públicos.

Este é, portanto, um trabalho de sistematização de abordagens e de tendências que procura identificar o estado atual do estudo da Comunicação Organizacional, destacando-se quer pela apresentação da evolução do campo no século XXI quer, principalmente, pela sua apresentação em língua portuguesa, algo que é pouco comum nesta disciplina.
Politicians self-representation on instagram: the professional and the humanized candidate during 2019 spanish elections
Authors: Gordillo-Rodriguez Maria-Teresa , Bellido-Perez Elena
Published: August 2022

Instagram has become an important tool to contact the audiences both in commercial and political communication. Of special interest is the use of this social network by politicians, who can use the image to portray a humanized version of themselves: it is not the candidate but the person who is talking to citizens through impacting images posted on their personal profiles. The present study posits that Instagram is a key tool for self-representation. This paper offers a specific study about the use of Instagram by the five main candidates in the Spanish general elections in 2019. The main aim of this paper is to study if the Spanish candidates showed themselves on Instagram in a more humanized way during the electoral campaign. Departing from Goffman’s theory about the presentation of the self, a content analysis has been carried out as methodology, where Goffman’s concepts have been operationalized. The analysis was applied to a total of 473 Instagram posts, covering both a pre-election period and an election period. Results show that Spanish candidates tend to show themselves as professional politicians, but some candidates of new parties increment their humanization in the elections period.

El engagement se vincula a la interacción y se detecta un uso masivo de redes sociales, mensajería instantánea y podcast. En menor medida, se incluyen innovaciones narrativas, gamificación o 360º.
What are the characteristics of “good” apps for young children? Perceptions of industry stakeholders
Authors: Dias Patrícia
Published: August 2022

Young children have become keen users of mobile digital devices. The “hAPPy kids” project mapped the views of different stakeholders - parents, children and industry - on the characteristics of “good” apps - that is, safe and beneficial for the development of children - and on the criteria for selecting and developing them. This article presents the perceptions of industry stakeholders such as digital content developers and broadcasters, policy-makers, and experts from the fields of Education and Psychology, gathered from 17 interviews with a purposive sample. They are aware of the demands of parents - learning and safety - and of children - fun and entertainment. They try to address both, and also value technical aspects of user experience.

Authors: Secilla-Garrido Mario , Hernando Ángel
Published: August 2022

Nowadays, Instagram and YouTube are becoming one of the biggest spaces for interrelation between people, specially between younger generations of the population. Nevertheless, there are few investigations based on the influence it can have on education, a reality that has come to stay and that cannot be ignored. With this research, this virtual environment has been addressed, dealing whit its analysis from an educational perspective, and taking as a reference four educational accounts on Instagram and four educational YouTube channels, whose educational quality has been determined through the curricular, pedagogical, didactic, technical, aesthetic, expressive aspects and their accessibility. In addition, the characteristics of these accounts and the edugramers and edutubers that manage them have been determined. When analyzing this reality, a mixed methodology has been used. For this, the methodological instruments that have been used throughout the research are the observation scale and the semi-structured interviews to an edugramer and two edutubers. The results show a great variety of educational accounts of quality in all aspects within the Instagram and YouTube platforms, as well as a series of common characteristics in these social media and a series of peculiarities shared by the educational instagramers and youtubers that manage these cyberspaces.

Published: August 2022

Digital media can provide an important contribution to the development of local communities by creating digital environments that facilitate the sharing of information, dissemination of knowledge and construction of organizational learning. Digital media can also promote interaction and collaboration processes among different regional agents, fostering a continuous flow of territorial based innovation. The study reported in this paper was carried out within the research activities of the (REMOVED) project, aiming to deepen the knowledge about the conditions that influence the dynamics of community-led territorial based innovation in the Centro Region of Portugal, focusing on the areas of Tourism, Health, and Wellness. As part of this project, a mobile application is being designed, aiming to strengthen the relationship among agents of local communities/entities and to promote mediation mechanisms among all stakeholders in the process of territorial based innovation. This paper presents the main concepts underlying the development of the REMOVED digital platform and the outcomes from a usability evaluation of the platform mobile app prototype. The first section discusses the most relevant topics that this paper covers. In the second section, an overview of the state of the art in the field of digital media used to promote territory-based innovation is presented. The third section describes the concept of the REMOVED digital platform and the main features of the prototype/mobile app. The fourth section addresses the methodology adopted for the evaluation of the prototype and the fifth exhibits the main outcomes of this process. Finally, the sixth and final section present the main conclusions about the potential of the REMOVED platform, and current and future research activities.
¿Cómo tener resultados de elite con la tecnología?: el rol de los andamiajes digitales en la apropiación de tecnologías digitales por clase social
Authors: Matozo Victoria
Published: August 2022

En el cruce entre los estudios de desigualdad social y digital, este artículo presenta los resultados de una investigación finalizada sobre la apropiación de tecnologías digitales (TD) en estudiantes de nivel medio de la Ciudad Autónoma de Buenos Aires (CABA). Las estrategias por clase de movilidad social son las que teóricamente se suman al desarrollo del concepto de brecha digital y apropiación para analizar la acumulación de capital digital en esta población a partir de la clase de origen de los individuos.

En primer lugar este trabajo presenta una tipología sobre las apropiaciones juveniles, marcando los destinos esperables a partir de las trayectorias de apropiación digital por clase social. En segundo lugar se presentan los casos disidentes en los que jóvenes de diferentes clases sociales se han apropiado de TD de forma “inesperada”, es decir, dando cuenta una trayectoria con destinos diferentes a otros jóvenes de la misma clase social a partir de la influencia de andamiajes digitales. Estos andamiajes serán fuente de reflexión ya que posibilitan el cambio de trayectorias y la movilidad social y digital, pudiendo ser otros individuos e incluso políticas públicas.
The emergence of technological tools to control Covid-19: a reinvention of panopticons
Authors: Barriga Antónia do Carmo
Published: August 2022

In the following text, we intend to discuss the digital epidemiological surveillance caused by the pandemic by Covid-19. The concern with surveillance and privacy is not new, but in the current pandemic situation, the role of the State in electronic surveillance, added to that which has long been played by the Big Tech that corner the market are known, it reconsiders these concerns. To what extent can we, or not, consider that the measures adopted to control contagion by the new coronavirus and in response to the pandemic are part of what were the “disciplinary societies”, as Foucault conceptualized them? To contribute to the answer to this question, the empirical approach that we propose to present aims to characterize the current panorama of the governmental use of technological tools to control the pandemic, as well as the limitations that many applications have come to reveal. To this end, information was collected and systematized divulged in various media from different countries.
Conceptualizing Media Generations: The Print, Online and Individualized Generations
Authors: Westlund Oscar , Färdigh Mathias A.
Published: August 2022

During the 1990s news publishers established an online presence and in the 2000s they developed cross-media news work. This has resulted in changing news accessing habits, with varied magnitude among generations. This article aims to construct theoretically sound news media generations, through statistical analysis of data from a nationally representative scientific omnibus survey conducted in 2010. Firstly the article presents a descriptive and explanatory analysis of how eight generational cohorts utilize news in print and/or online and/or mobile. Secondly these findings are used for merging the generational cohorts into a conceptualization involving three media generations. The print generation (1920s- 1940s) shows high probability (70%) and scored its highest value for reading only printed newspaper (Pearson’s r = .135). The online generation (1950s-1970s) shows high probability (66%) and scored highest of online only news accessing (Pearson’s r = .135). The heterogeneous news usage patterns exhibited by the individualized generation (1980s-1990s) were accommodated for by two cohorts. The online cohort shows high probability for online-only news usage (60%) and a positive correlation (Pearson’s r = .065). The cross-media cohort marks high probability for cross-media use (77%) and the highest value for cross-media use (Pearson’s r = .141).
Differentiated strategies for digital innovation on television: Traditional channels vs. new entrants
Authors: Ranaivoson Heritiana , Farchy Joëlle , Gansemer Mathilde
Published: August 2022

Digitization has greatly influenced the functioning of the television industry. This paper analyzes in particular how French television channels have innovated and adapted to digital technologies. We begin with a typology of innovation in the media by drawing a distinction between product innovations and process innovations, as well as between companies according to whether they were the first to adopt an innovation, or only adopted it once it was already well established in the field. A total of 21 criteria for innovation are analyzed for each of the 15 TV channels in our sample.

This paper shows that TV channels have varied innovation strategies. Rather than some channels being innovators on all criteria and others being followers on all criteria, we show that channels adopt, more or less rapidly, certain types of innovation according to the channels’ characteristics. The characteristics that play the greatest role are the age of the channel, whether it is public or private, and whether it is general or thematic.

Trends and transformations within cultural journalism: a case study of newsmagazine Visão.
Authors: Torres da Silva Marisa , Santos Silva Dora
Published: August 2022

In the last ten years, the configuration of cultural journalism, regarding editorial and business models, has undergone profound changes. Nowadays, it cannot be separable from the context of cultural and creative industries, which requires a redefinition and expansion of the field, reinforcing its complexity, broadness and heterogeneity (Rivera, 2003). The emergence of more consumer-driven formats within journalism broadly speaking (Fürsich, 2012) is thus transforming cultural journalism into a continuum between culture, lifestyle and consumption (Kristensen, 2010), challenging existing definitions of cultural journalism as a distinct journalistic object (Kristensen & From, 2012).

In this article, we intended to verify whether the identified trends are present in the Portuguese press media environment, using a newsmagazine (Visão) and its supplement (Visão Sete) as a case study. Combining quantitative (content analysis) and qualitative methodological approaches (interviews and discourse analysis), we stated that while Visão Sete is the clear example of the contemporary approach to culture as a service and a consumer good related to lifestyle, the culture section of the newsmagazine conveys a classic (and somewhat reductive) approach to culture, primarily related to artistic manifestations – which lead us to infer that nowadays newspapers and magazines are still looking for its position regarding cultural journalism.
O spin doctoring em Portugal: Perspectivas de governantes, jornalistas e assessores de comunicação que operam na Assembleia da República
Authors: Ribeiro Vasco
Published: August 2022

Nos meados da década de 80 o termo inglês “spin doctor” começou a ser a melhor forma de classificar os assessores de imprensa que, ao serviço de partidos e governos, manipulavam jornalistas e, consequentemente, a opinião pública (Campbell, 2002; Kurtz, 1998; Maltese, 1992; Manning, 1998; Safire, 1984; Sumpter & Tankard, 1994). Partindo deste pressuposto, e tendo como objetivo central tentar perceber se há, de facto, spin doctoring em Portugal, decidiu-se realizar entrevistas de elite a elementos que “habitam” o centro da atividade política nacional e o núcleo da maior concentração e produtividade de jornalismo político em Portugal - a Assembleia da República. Realizámos, assim, 30 entrevistas ao trinómio políticos-assessores de imprensa – jornalistas; nomeadamente 1) aos assessores de imprensa que desenvolvem a sua atividade para os diferentes grupos parlamentares; 2) aos jornalistas ‘residentes’ no Parlamento e que lidam diariamente com estes profissionais; e 3) aos políticos que recorrem e contratam os seus serviços. Ressalve-se entre os entrevistados encontram-se dois ex-primeiros-ministros de Portugal, Pedro Santana Lopes e José Sócrates, e vários assessores de imprensa e consultores que serviram diversos partidos e vários governos. Entre os resultados, não só se evidencia a existência desta atividade em Portugal, como também se identificam os seus principais protagonistas.
A Comunicação Estratégica aplicada à divulgação da Ciência. O caso do Centro de Estudos de Comunicação e Sociedade
Authors: Magalhães Ricardina
Published: August 2022

A ciência é uma atividade que torna possível o desenvolvimento tecnológico, social, cultural e económico. É importante avaliar a forma como o mundo científico comunica, nomeadamente a capacidade de adequação da comunicação da ciência às novas ferramentas e às respetivas formas de interação com os públicos. Referimo-nos à comunicação digital que traz potencialidades acrescidas, face à comunicação tradicional. Na verdade, procuraremos demonstrar que o investimento que é feito na comunicação online, inserida numa estratégia de comunicação sólida e coerente, pode trazer benefícios acrescidos à divulgação científica.

O Centro de Estudos de Comunicação e Sociedade tem, como preocupação primária, a divulgação dos resultados da sua investigação. A atual inquietação à volta do desinvestimento na ciência torna a avaliação das políticas de comunicação levadas a cabo no CECS uma necessidade premente, para demonstrar a importância da sua atividade e do financiamento necessário à sua prossecução.

Neste contexto, esta investigação procura desvendar a importância da comunicação online, no âmbito da comunicação da ciência e da investigação científica.

Para este efeito, faremos uma auditoria de comunicação focando-nos nas ferramentas de comunicação online do CECS, procurando perceber a importância da utilização destas na estratégia de divulgação científica.
O sistema discursivo de Periodicidade em texto argumentativo
Authors: Olioni Raymundo da Costa , Rossi Angela Maria , Fuzer Cristiane
Published: August 2022

O sistema discursivo de Periodicidade proposto por Martin (1992) e Martin e Rose (2007) para a análise do fluxo discursivo em textos é fundamentado na Linguística Sistêmico-Funcional (Halliday 1967, 1985, 1994; Halliday & Matthiessen 2004, 2014), mais precisamente nos conceitos hallidayanos de Tema e de Informação Nova (Novo), além dos conceitos de progressão temática e de hiperema (Daneš 1974) e de método de desenvolvimento textual e ponto (Fries 1981; 1995). Neste artigo, analisamos como ocorre o fluxo de informação em um texto argumentativo, verificando a relação dos Temas em diferentes níveis (hiperTemas e macroTemas) com o método de desenvolvimento e sua relação com o gênero de texto exposição de um ponto de vista. Também averiguamos a relação dos Novos oracionais com o macroNovo, o qual foca na expansão dos significados ideacionais em torno do campo do texto e coincide com a etapa de Reiteração da tese. Constatamos, no texto analisado, um método de desenvolvimento simples, com uma hierarquia de periodicidade em que unidades menores do discurso se estruturam dentro de unidades maiores.
Energy gap–refractive index considerations in perovskites

Published: August 2022

This work proposes a simple model for determining the relationship between static refractive index and energy bandgap. Some evidence from the literature agrees well with the proposed equations. The notions of tolerance factor and octahedral factor are used to establish the upper and lower boundaries of the refractive index in oxide and halide perovskites.
Bond performance of ribbed bars in concrete: effects of loading rate and lateral tension
Authors: Li Xin-Ru , Wu Zhi-Min , Zheng Jian-Jun , Yu Rena C.
Published: August 2022

This paper presents an experimental study on the effects of lateral tension and loading rate on the local bond performance of ribbed bars in concrete. The results show that, up to a loading rate of 10 mm/s, the mode of bond failure is independent of the loading rate but is closely related to the cover depth, concrete grade and level of lateral tension. It is also shown that the bond strength of ribbed bars increases with the increase of loading rate but decreases with an increase in lateral tension. The increase or decrease ratio becomes larger when splitting failure occurs. Specifically, for pull-out and splitting failure, the bond strength decreases by 8% and 22% when the lateral tension increases from 0.0 to 0.6 times the tensile strength of concrete but increases by 22% and 28% when the loading rate increases from 0.01 to 10 mm/s, respectively. The slip at peak bond stress is rate-insensitive. It can be taken as 0.18 times the rib spacing for pull-out failure but decreases linearly with the increase of lateral tension for splitting failure. Finally, a bond stress–slip model with three parameters is suggested for different levels of lateral tension and loading rates.
Protección ambiental y disputas comerciales: ¿déficit de eficacia o locus inadecuado?

Published: August 2022

Este artículo está dedicado a analizar las disputas comerciales relacionadas con la protección ambiental sometidas al sistema de solución de controversias del MERCOSUR y aquello de la Organización Mundial del Comercio. La investigación trae un panorama sobre las posibles dificultades para la promoción efectiva de la protección del medio ambiente en sistemas diseñados para la solución de disputas comerciales. A través del análisis de decisiones sobre casos confrontados con esos estándares, las conclusiones confirman la hipótesis de que los intereses comerciales tienden a prevalecer imponiendo un rol secundario a la protección del medio ambiente.

Published: August 2022

Este capítulo visa fazer uma análise da (crise da) identidade europeia através de um conjunto de cartoons coligidos a partir da rede social Facebook, na tentativa de compreender as narrativas produzidas acerca da União Europeia atravessada por eventos críticos mediatizados, designadamente a crise migratória ou dos refugiados e o Brexit. As representações visuais analisadas revelam a complexidade das narrativas identitárias que circulam nesta rede social sobre a Europa, ao sinalizarem contradições, impasses e ameaças da integração europeia na última década, mas também promovem a construção de identidades reflexivas, isto é, ancoradas na relação prática dos europeus com o projeto da União Europeia.

Authors:   CECS – Centro de Estudos de Comunicação e Sociedade, Pinheiro Neves José
Published: August 2022

Neste artigo, são descritas algumas ferramentas teóricas e metodológicas que permitem compreender o fenómeno do ativismo estético nas redes digitais. Intenta-se responder a duas questões centrais: 1. Como estudar, qual a melhor metodologia para compreender o fenómeno do ativismo de tipo estético nas redes digitais? 2. Quais os conceitos mais adequados para o caracterizar? Para tal, é feita uma travessia teórica e epistémica sobre as teorias dos novos média, seguida de uma análise a alguns memes ativistas que circulam, ainda que de modo periférico, no Facebook. No final, conclui-se que uso de ferramentas qualitativas de investigação-experimental, uso da auto-etnografia e o envolvimento pessoal na pesquisa, de forma ética e pistemologicamente controlada, envolve os agentes principais e, acima de tudo, a serem capazes de esboçar e comparar experimentações metodologicamente controladas e dialógicas.
Potential Use of Lactobacillus gasseri G10 Isolated from Human Vagina along with Intrauterine Devices (IUD) to Prevent Pathogen Colonization
Authors: AKTAS Busra
Published: August 2022

Intrauterine devices (IUDs), well effective long-term contraception methods used around the world, are potential reservoir for pathogens and carry risk of reproductive-tract infections such as bacterial vaginosis and vulvovaginal candidiasis. A healthy vagina is dominated by Lactobacillus involved in protecting reproductive system against pathogens. This study aims to investigate the impact of L. gasseri G10 (G10), a vaginal isolate, and its Exopolysaccharide (EPS) on adherence of Staphylococcus aureus and Candida albicans to IUD-tail. Three conditions were simulated to examine if G10 with/without EPS is capable of displacing, excluding, and competing pathogen adhesion to IUD. Inhibitory impact of EPS at various concentrations on pathogen adherence was also evaluated with co-incubation. G10 blocked by co-incubation (97%) and displacement (46%) of S. aureus adherence to IUD tail and displaced C. albicans attached to IUD with about 99%. Compared with S. aureus, the biofilm formation by C. albicans was highly susceptible to EPS. All concentrations of EPS inhibited the adherence of C. albicans (81-97%); however, no significant reductions were observed in S. aureus adherence. Moreover, G10 and EPS together reduced the adherence of both S. aureus (>99%) and C. albicans (94-98%) through all three mechanisms. This study indicates that G10 and its EPS have the ability to inhibit adhesion of S. aureus and C. albicans to IUD and potential use in intravaginal products to prevent/manage IUD associated infections in women. The results suggest development of a new way of applying IUD along with probiotic agents alone or as synbiont.
Effect of Iron on Some Parameters Recombinant Pseudomonas aeruginosa Carrying Vitreoscilla Hemoglobin Gene
Authors: KAHRAMAN Hüseyin
Published: August 2022

In this study, the effects of iron presence on some bacterial parameters of Pseudomonas aeruginosa and its recombinant bacteria carrying Vitreoscilla hemoglobin on its chromosome were investigated for the first time. These parameters are; optical density, pH, glucose, trehalose production and biomass. Parameters; It was studied at 37 °C and 250 rpm ventilated conditions depending on time. Bacteria have developed mechanisms by which they can resist heavy metal stress with many other mechanisms, including making metals less toxic and excreting them out of the cell. The Efflux system is the most widely used mechanism. The bacterium that makes the best use of these mechanisms is P. aeruginosa, which has an environmental and versatile feature. In the presence of LB alone, an increase was observed in the first 48 hours and a decrease of 43% in the other time periods, especially in the 96th hour compared to the control. The highest increase was detected in the 48th time periods, up to 259% in the 3,32. When iron was added to the medium, significant increases were observed in all time periods compared to the controls and these increases reached 575% at 72 hours. In the same time periods, the maximum value of OD600 4.55 was reached.
Information Externalities, Funding Liquidity, and Fire Sales
Authors: Chang Jin-Wook , Altinoglu Levent
Published: August 2022

We develop a theory of learning in a model of fire sales and collateralized debt to study how beliefs about fundamentals are shaped by market conditions. Agents exchange short-term debt contracts to invest in a long-term risky asset, and receive shocks to the opportunity cost of funds (cost shocks) and news about the fundamental of the asset, both of which are private information. Asset prices play a dual role of clearing markets and conveying agents' private information, but markets are informationally inefficient: Agents can partially, but never fully, infer their counterparties' private information from asset prices. The informational inefficiency of markets is more acute when liquidity conditions are especially tight or loose, as this impairs ability of prices to reveal private information about fundamentals. As a result, beliefs about fundamentals are shaped endogenously by cost shocks which are orthogonal to fundamentals, leading to socially costly booms and busts in asset prices. The equilibrium is constrained inefficient due to an information externality in which agents do not internalize how their choices affect the information set of other agents. Interventions in funding markets can stabilize asset prices by altering perceptions of risk.
Investigation of the knowledge of South African high school rugby coaches on concussion and the return-to-play protocol
Authors: Abel Nico , Grant Catharina Cornelia , Janse van Rensburg Dina C
Published: August 2022

Background: Coaches are pivotal in the management of concussed players. Assessing the knowledge of high school rugby coaches with regard to concussion management will enable relevant future education on this topic to be covered.
Objectives: To investigate the knowledge of South African high school rugby coaches on concussion symptom recognition, knowledge and stepwise return-to-play (RTP) protocols.
Methods: A cross-sectional descriptive study involving 143 first team, high school rugby coaches was completed via an electronic questionnaire. Independent variables included coach demographics, qualifications, experience, BokSmart accreditation, and school size. Dependent variables included knowledge scores on concussion symptoms, general concussion knowledge, stepwise RTP and Maddocks questions. Relationships between total scores for different demographic groupings were established using non-parametric techniques.
Results: The coaches had high general, symptom and overall concussion knowledge scores (77% - 80%) in contrast with low RTP scores (62%) and very low Maddocks questions knowledge scores (26%). The 35-44-year age group received top scores for symptom recognition (p=0.034) and total concussion knowledge (p=0.041). Larger category school coaches (p=0.008) and BokSmart accredited coaches (p=0.041) outperformed all other coaches in general concussion knowledge and total knowledge, respectively. However, respondents were not familiar with emotional symptoms or the importance of cognitive rest after a concussion. Educational programmes were the most popular knowledge source for coaches.
Conclusion: In general, coaches presented with good general concussion knowledge but lesser expertise on emotional symptoms, cognitive rest and RTP management. Modifiable predictors of knowledge included the expansion of BokSmart accreditation, focussing information sessions on smaller rugby size schools and the education of coaches younger than 35 years or older than 45 years of age.

Depremden sonra hasar görmüş bölgelerde yürütülen yerinde inceleme çalışmalarında çoklu deprem etkileri sıklıkla görülmektedir. Birçok yapı, ana depremi hasarsız ya da az hasarlı atlatırken, rijitlik ve dayanımı azalmış yapıya artçı deprem etkimesi durumunda gözlenen hasar genellikle artmaktadır. Bazı durumlarda yapı ana depremi güvenli bir şekilde atlatırken, artçı depremden sonra göçebilmektedir. Literatürde, çoklu deprem serilerine maruz kalmış düzensiz betonarme yapıların sismik davranışlarını inceleyen az sayıda çalışma vardır. Bu çalışmada, çoklu deprem serilerinin düzensiz betonarme yapıların kalıcı deplasman değerlerine etkilerini araştırılmaktadır. Bu sebeple, düzensiz üç adet mevcut betonarme yapı seçilmiş ve çoklu deprem serileri altında, doğrusal olmayan zaman tanım alanında analizleri gerçekleştirilmiştir. Malzemedeki bozulma etkilerini incelemek için, seçilen yapılar hem azalım etkilerini dikkate alabilen hem de azalım etkilerini dikkate alamayan malzeme modelleri kullanılarak analiz edilmişlerdir. Analiz sonuçlarının incelenmesinden, azalım etkilerini dikkate almayan malzeme modellerinin çoklu deprem serileri altındaki sismik davranışı gerçekçi bir şekilde yansıtamadıkları belirlenmiştir. Bu sebeple bozulma etkilerini doğru olarak yakalayabilmek için azalım etkilerini dikkate alan malzeme modellerinin kullanılması gerekmektedir. Ayrıca, çalışmanın sonucunda düzensizlik etkilerinin kalıcı deplasmanları arttırdıkları belirlenmiştir.

There is evidence from research that dietary lifestyle influences health and mental well-being but there is limited understanding of the mechanism in Nigerian adult population. This study evaluated association of food intake with obesity and subjective cognitive complaints (SCCs) in Nigerian adults. We carried out a cross-sectional study of 1338 random samples aged 18-87 years who were visiting six different public hospitals in the southwest Nigeria between March 2016 and April 2016. Standard food frequency questionnaire (FFQ) and SCC questionnaire were used while anthropometric data were measured using standard clinical procedures. Associations were determined by linear and unconditional logistic regressions, after adjustment for age, ethnicity, education, gender, marital status, family type, alcohol and smoking status. Consumption of four different foods was significantly associated with SCC while one food intake was significantly associated with obesity measure (i.e., body mass index): meat product (Adjusted Odds Ratio (AOR), 1.002; 95% Confidence Interval (CI), 1.001-1.004; P <.0001), and sugary snacks (AOR, 1.007; 95% CI, 1.002-1.011; P <.01) were associated with increased SCCs whereas consumption of cereal products (AOR, 0.999; 95% CI, 0.998-1.000; P <.01) and potatoes (AOR, 0.998; 95% CI, 0.996-1.000; P <.05) were associated with decreased levels of SCCs. Consumption of non-alcoholic beverages was associated with decreased BMI levels (AOR, 0.998; 95%CI, 0.997-1.00; P <.05). Linear regression analyses on these data largely recapitulated the results. In conclusion, consumption of cereals, potatoes and non-alcoholic beverages appear beneficial to health and the findings could serve as an intervention strategy for tackling SCCs and obesity.

Published: August 2022

Currently, acoustoelectronics devices (filters, delay lines, resonators, etc.) are used in various radio engineering systems. In addition, they are used in microsystem technology as the basis for microminiature sensors for various purposes — sensors ofphysical quantities (temperature, micro-displacement, acceleration, etc.). In the range from tens of megahertz to 2.5 GHz, surface acoustic wave micro-devices have become widespread. The field of technical applications of SAW micro-devices is rapidly developing. In order to withstand competition from other technologies, it is clear that it requires not only the improvement of common topological solutions, but also the development and research of new designs of SAW micro-devices capable of reaching limiting and critical parameters. It is also necessary to use modern methods and approaches to device modeling. Purpose: to review and analyze the problems of the current state of SAW devices from the point of view of achieving limit parameters. Results: It is shown that the stages of structural and parametric synthesis of topology are key aspects in the design of devices with limiting parameters. Some results of research and development of surface acoustic waves devices based obtained in the field of creating ultra-narrowband filters, ultra-wideband delay lines and unique radio tags based on a multi-band coupler are presented. A filter with minimal unevenness of the group delay time for a class of transversal filters is presented. It is shown that obtaining devices with limiting and critical parameters is possible only on the basis of interfacing the development of structural and technological, materials science, physical and circuit design principles. Modern approaches to analyzing the output characteristics of surface acoustic wave devices and wave processes in piezoelectric substrates are described.

La participación y empoderamiento de la comunidad en materia de formación de políticas públicas es poco estudiada, sin embargo, cobra cada día más vigencia la necesidad de integración Estado-sociedad en Latinoamérica para el desarrollo local. En este contexto, el objetivo de este estudio es sistematizar el proceso de intervención socio comunitaria hacia la formulación de políticas públicas en el ámbito del turismo, como proceso legitimador de la socialización entre lo gubernamental, comunitario e institucional. Metodológicamente se desarrolla una investigación cualitativa, de corte interpretativo, método fenomenológico, empleando un diseño de sistematización propio de los trabajos en procesos sociales, que permite apropiarse de los aprendizajes de las experiencias vividas y compartirlos, en este caso, mediante gestión social para un turismo sostenible en el municipio Usiacurí (Colombia). El producto es la sistematización infográfica de un proceso que cierra brechas en cuanto al empoderamiento comunitario y su vinculación con el desarrollo social a través de la formación de política pública, destacando su aporte a las ciencias sociales a través del análisis del comportamiento, situaciones y circunstancias de cada fase, para la legitimación de la participación y toma de decisiones de la comunidad y del Estado. Concluyendo que, la participación activa y colaborativa de la comunidad organizada y del Estado en la formación de política pública favorece su legitimación frente a la sociedad y este hecho da cuenta que la gestión no es neutra.
