A Review on the Physicochemical Properties of γ-irradiated Copra (Dried Cocos nucifera L.)
Authors: L. De Mesa Michael John , C. De Vera Flordeliza
Published: August 2022

Copra or dried coconut kernel is a primary product of coconut and is known to be a source of coconut oil. It is found to be highly susceptible to Aspergillus flavus that can cause aflatoxin contamination during pre- and post-harvesting processes. Therefore, researchers have been looking for a method to reduce aflatoxins in copra to a safe level while positively affecting its properties. The γ-irradiation is found to induce growth inhibition of A. flavus in copra at low irradiation doses (0 to 3 kGy) using a semi-commercial irradiator. This result is supported by other food samples having a high reduction of aflatoxins. Currently, no studies examined the influence of γ-irradiation on the physicochemical properties of copra. Hence, this study used the properties of different γ-irradiated commodities that are similar to copra to justify the need of investigating properties in irradiated copra. Gamma irradiation has the potential to increase the fat and ash content, decrease protein and crude fiber content at higher absorbed doses, and expected no changes in moisture content of the irradiated copra. In addition to this, the effect of the irradiation on carbohydrate content, phytochemical profile, and water activity may vary in significant findings until further investigations have been made on irradiated copra. However, the researchers recommended that the microbial activity of A. flavus and characterization of the physicochemical properties of irradiated copra were necessary for future experimentations.

Objectives

Timolol maleate is used for the treatment of glaucoma and metabolized by cytochrome CYP2D6 in the liver. The aim of this study was the evaluation of the influence of CYP2D6*4 and CYP2D6*10 gene polymorphisms on the safety of medications containing 0.5% of timolol maleate as glaucoma treatment in patients with primary open-angle glaucoma (POAG).

Methods

105 patients with POAG were prescribed glaucoma medications, containing 0.5% timolol maleate. The safety of glaucoma treatment was determined by electrocardiography (ECG) (to assess heart rate (HR) and PQ interval) and blood pressure (BP) measurements. The real-time polymerase chain reaction method was used for the detection of single nucleotide polymorphisms (SNP).

Results

The risk of adverse drug reactions was higher in patients with the CYP2D6*4 GA genotype compared with GG: mean HR change at 1 month (2.88 ± 4.68 and 6.44 ± 5.57, p<0.001) and 6 months (5.14 ± 8.93 and 7.88 ± 5.65, p<0.001), mean PQ interval change at 1 (0.01 ± 0.031 and 0.02 ± 0.022, p=0.003) and 6 months (0.01 ± 0.032 and 0.02 ± 0.024, p=0.003). The risk of adverse drug reactions was higher in patients with the CYP2D6*10 CT genotype compared with CC: mean HR change at 1 month (2.94 ± 4.65 and 6.34 ± 5.66, p<0.001) and 6 months (5.20 ± 8.90 and 7.78 ± 5.75, p<0.001), mean PQ interval change at 1 (0.01 ± 0.032 and 0.02 ± 0.021, p=0.014) and 6 months (0.01 ± 0.033 and 0.02 ± 0.022, p=0.014).

Conclusions

CYP2D6*4 and CYP2D6*10 gene polymorphisms may affect a higher risk of timolol-induced bradycardia and increased PQ interval of treatment medications containing 0.5% of timolol maleate in patients with POAG.
Improving diagnostic decision support through deliberate reflection: a proposal
Authors: Schmidt Henk G. , Mamede Sílvia
Published: August 2022

Digital decision support (DDS) is expected to play an important role in improving a physician’s diagnostic performance and reducing the burden of diagnostic error. Studies with currently available DDS systems indicate that they lead to modest gains in diagnostic accuracy, and these systems are expected to evolve to become more effective and user-friendly in the future. In this position paper, we propose that a way towards this future is to rethink DDS systems based on deliberate reflection, a strategy by which physicians systematically review the clinical findings observed in a patient in the light of an initial diagnosis. Deliberate reflection has been demonstrated to improve diagnostic accuracy in several contexts. In this paper, we first describe the deliberate reflection strategy, including the crucial element that would make it useful in the interaction with a DDS system. We examine the nature of conventional DDS systems and their shortcomings. Finally, we propose what DDS based on deliberate reflection might look like, and consider why it would overcome downsides of conventional DDS.

The effect of virtual laboratory simulations on medical laboratory techniques students’ knowledge and vocational laboratory education
Authors: Keleş Didem , Bulgurcu Alihan , Feyzioğlu Demir Esra , Şemin Ilgi Makbule
Published: August 2022

Objectives

Virtual laboratory simulations (VLSs) are computer-based tools that offer unlimited application options in scientific, medical, and engineering fields. The aim of this study was to evaluate whether VLSs are efficient learning tools and how these simulations can be integrated into laboratory practice in medical laboratory education.

Methods

In this pre-test/post-test control group study, 32 volunteers were randomly assigned to either experimental or control groups. The experimental group performed laboratory simulations based on biochemistry and microbiology and then completed a self-report survey to evaluate their satisfaction and beliefs about simulations.

Results

In the experimental group, post-test scores of each simulation were significantly elevated compared to pre-test scores; however, pre- and post-test scores of control group were statistically the same. The experimental group agreed that these simulations should be applied before theoretical lectures and laboratory practices. They also highlighted that translating from English to their native language creates difficulties in applying and understanding the simulation.

Conclusions

We emphasized that VLSs are excellent learning tools that increase not only the knowledge but also the self-motivation and focus of the students. Based on feedbacks, native language options are necessary to enable the students to achieve equality of opportunity in education.
Turner syndrome and neurofibromatosis type 1: the unusual combination of two common genetic disorders
Authors: Vieira Inês , Lopes Sofia , Bastos Margarida , Ruas Luísa , Rodrigues Dírcea , Paiva Isabel
Published: August 2022

The coexistence of neurofibromatosis type 1 (NFT1) and Turner syndrome (TS) has only been reported in a few patients and may represent a diagnostic challenge. We describe the case of a 16-year-old girl, with a prior clinical diagnosis of NFT1, who was referred to Endocrinology appointments for the etiological study of primary amenorrhea. Evaluation of the anterior pituitary function was requested and hypergonadotropic hypogonadism was detected. During the etiological study, a 45X karyotype was found and TS was diagnosed. The fact that NFT1 can also be associated with short stature, short broad neck and hypertelorism was likely responsible for TS being diagnosed in late adolescence. As both TS and NFT1 are relatively common genetic disorders, it is important to be alert to the possibility that the presence of one disease does not invalidate the other.

Learning points

The concomitant presence of two syndromes in the same patient is unlikely and represents a diagnostic challenge.

Some phenotypic characteristics and clinical manifestations may be shared by several syndromes.

Some syndromes, such as neurofibromatosis type 1 may have very heterogeneous presentations.

It is important to be alert to the characteristics that are not explained by the initial diagnosis.

If such features are present, diagnostic work-up must be performed regardless of the initial syndromic diagnosis.

Após havermos analisado o termo a quo de uso de um par de construções verbais perifrásticas em covariação no âmbito do discurso metalinguístico português produzido entre o século xvi e o século xix – verbo auxiliar estar + verbo principal (pleno ou auxiliado) no gerúndio e verbo auxiliar estar + preposição a + verbo principal (pleno ou auxiliado) no infinitivo –, coligimos as ocorrências dessas construções na primeira novela portuguesa contemporânea, Viagens na minha terra, publicada, em Portugal, na primeira metade do século xix, a fim de assinalarmos um contorno do reflexo da dinâmica da língua portuguesa à época nessa obra fundamental do movimento do Romantismo. Tendo partido de pressupostos importantes da teoria da variação e da mudança linguísticas, demos primazia à realização de covariantes de uma variável interna de cariz aspetual.
Dudak Damak Yarıkları ile İlgili İnternete Dayalı Bilgi Kalitesinin Değerlendirilmesi
Authors: EKİCİ Ömer , ONGAN Bünyamin
Published: August 2022

Amaç
Günümüzde internet hem hastalar hem de sağlıklı kişiler tarafından yaygın olarak kullanılan önemli bir bilgi kaynağı olmuştur. Bu çalışmanın amacı, dudak damak yarıkları ile ilgili internet ortamındaki bilgi kalitesini DISCERN aracı kullanarak değerlendirmektir.
Gereç ve Yöntemler
Türkiye’de sık olarak kullanılan Google, Yandex, Yahoo ve Bing arama motorlarında, 20 Mayıs 2020 tarihinde, “dudak yarığı”, “damak yarığı”, “dudak- damak yarığı” ve “tavşan dudak” anahtar sözcükleri ile internet araştırması yapıldı. Arama motorlarının her birinde her terim ayrı ayrı aranarak elde edilen ilk 10 internet sitesi saptandı. Toplamda 160 internet sitesinden 55 internet sitesi 16 sorudan oluşan DISCERN aracı kullanılarak değerlendirildi.
Bulgular
Değerlendirilen internet sitelerinin DISCERN puanı 16 ile 53 arasında değişti(ortalama puan 32.72). Toplam 55 adet internet sitesinden yalnızca üçü “iyi” olarak sınıflandırılırken hiçbir site “mükemmel” olarak sınıflandırılamadı. Değerlendirilmeye dahil edilen internet sitelerindeki en basit hata, verilen bilgilere kaynak gösterilmemesi, tedavi seçeneklerinin genel yaşam kalitesini nasıl etkilediğinin açıklanmaması ve konu ile ilgili gereksinim duyulabilecek ekstra bilgi kaynaklarına yönlendirme yapılmaması idi.
Sonuç
İnternet ortamındaki dudak damak yarıkları ile ilgili bilgi sunan Türkçe sitelerin bilgi kalitesinin genel olarak düşük olduğu görüldü. Dudak-damak yarıklı bireyler ve ailelerin ihtiyaç duydukları doğru, tarafsız, anlaşılır, bilimsel kanıtlara dayalı bilgiler sunan, bilgi kalitesi yüksek web sitelerine ihtiyaç vardır.
Anahtar Kelimeler
İnternet; sağlık bilgi yönetimi; sağlık okur-yazarlığı; dentofasiyal deformiteler.

Published: August 2022

El consumo de cigarrillo ha tenido un gran impacto en la salud, por lo que es urgente y necesario trabajar en la generación de interés en la cesación. El objetivo de la presente investigación fue el diseño y validación del Cuestionario de Clasificación de Etapas de Cambio y Cesación de Consumo de Cigarrillo/Tabaco CCET, que permite la categorización del consumidor de acuerdo con las siete etapas descritas en el modelo teórico Proceso de Adopción de Precauciones que propuso Weinstein en 1988. El CCET consta de 16 ítems que interrogan acerca de las características definidas para cada fase de cambio de la conducta del individuo, consumo y el logro de la cesación. La muestra estuvo conformada por 200 estudiantes de educación superior fumadores (138 hombres y 62 mujeres) entre los 18 y 57 años. Se determinó la validez de contenido a través del juicio de expertos quienes analizaron los criterios de redacción, pertinencia y suficiencia de cada una de las preguntas utilizadas en dicho cuestionario, se realizó la aplicación en su versión definitiva para determinar las características técnicas de acuerdo con el Modelo de Rasch. Del mismo modo que en estudios previos buena parte de la muestra presento ubicación en las primeras etapas, es decir no necesariamente con deseo de dejar de fumar.

Authors: Jorquera Gutiérrez Ricardo
Published: August 2022

A partir del concepto de Bienestar Psicológico de Carol Ryff (1989), el objetivo del presente estudio fue describir y comparar este constructo en trabajadores de diversas industrias y estudiantes de educación superior. La muestra fue de 415 participantes, seleccionados mediante muestreo de tipo no probabilístico intencional. Del total de la muestra, el 76.9 % (n = 319)  fueron trabajadores de industrias y un 23.1 % (n=96) estudiantes de educación superior. Se utilizó la Escala de Bienestar Psicológico de Ryff (Diaz et ál, 2006) en su versión adaptada. Se encontraron diferencias significativas entre trabajadores y estudiantes. Las mayores diferencias se observan al comparar la muestra según ingresos familiares. Según el sexo y la edad solo se encuentran diferencias en el componente de relaciones positivas. Es posible concluir respecto al importante papel del trabajo sobre el bienestar psicológico y de cómo este varía de acuerdo a las condiciones socioeconómicas del trabajador y del rubro en el cual se desempeña.
Efectos del entrenamiento en marcos relacionales de condicionalidad sobre el responder relacional deíctico
Authors: Quiroga-Baquero Luis A. , Rendón María Isabel , Montoya-Rodríguez María M. , Salas-Cuervo Daniel C.
Published: August 2022

According to Relational Frame Theory, perspective taking is conceived as an arbitrarily applicable relational pattern of relational responding under the control of personal, spatial, and temporal deictic contextual cues. Furthermore, the ability to respond relationally under the control of conditional contextual cues is assumed to be necessary. However, no empirical evidence has been reported to identify the relationship between conditionality frames and accuracy in deictic relational responding. The study aimed to analyze whether training in conditionality frames could facilitate performance on deictic responding. Four children with normalized development participated and were divided into two experimental conditions (C1 and C2). Participants in both conditions were exposed to an evaluation protocol and training on deictic frames. In turn, only C2 participants were exposed to an evaluation and training phase in conditionality frames before the training in deictic frames. Results showed that all the participants exhibited improvements in their post-test performances on deictic relations and that the C2 participants performed better with respect to their pre-test on the levels of greater deictic complexity after training in conditional frames. We discuss the need for more naturalistic perspective-taking protocols that allow us to investigate how relational terms are developed and abstract the role of contextual cues that allow us to interpret, attribute, and predict another’s behavior.
La aplicación del valor razonable en Costa Rica: un estudio exploratorio
Authors: Sosa Mora Eduardo
Published: August 2022

Este artículo presenta los resultados de un estudio realizado con base en los estados financieros auditados al 31 de diciembre de 2020, de 33 empresas y entidades costarricenses, con el propósito fundamental de explorar en qué medida aplican el modelo de valor razonable. Dada su naturaleza exploratoria, este trabajo pretende aportar información significativa para futuras investigaciones, más que inferir sus resultados a la población de empresas costarricenses.

El estudio permitió evidenciar que el modelo de valor razonable se encuentra en una etapa incipiente en Costa Rica. No es la principal base de medición contable en las entidades estudiadas y se emplea, primordialmente, en la medición de activos financieros, en entidades financieras y empresas no financieras. Su uso para valorar activos no financieros se limita a la revaluación de bienes inmuebles, así como a la medición de propiedades inmobiliarias principalmente con propósitos informativos, lo cual contrasta con el auge del modelo en las Normas Internacionales de Información Financiera, pero concuerda con los resultados de estudios similares realizados en varios países de América Latina.

Background and Objectives: The most effective treatment of infertility is in vitro fertilization (IVF). IVF with Preimplantation Genetic Testing (PGT) allows to identify embryos with a genetic abnormality associated with a specific medical disorder and to select the most optimal embryos for the transfer. PGT is divided into structural rearrangement testing (PGT-SR), monogenetic disorder testing (PGT-M), and aneuploidy testing (PGT-A). This study mostly analyzes PGT-SR, also describes a few cases of PGT-M. The aim of this study was to implement PGT procedure at Vilnius University Hospital Santaros Klinikos (VUHSK) Santaros Fertility Centre (SFC) and to perform retrospective analysis of PGT procedures after the implementation.Materials and Methods: A single-center retrospective analysis was carried out. The study population included infertile couples who underwent PGT at SFC, VUHSK from January 01st, 2017 to December 31st, 2020. Ion PGM platform (Life Technologies, USA) and Ion ReproSeq PGS View Kit (Life Technologies, USA) were used for the whole genome amplification. Results were assessed using descriptive statistics.Results: PGT was successfully implemented in VUHSK in 2017. During the analyzed time period, thirty-four PGT procedures were performed for 26 couples. Two procedures were performed in 2017, 7 procedures – in 2018, 13 – in 2019, and 12 – in 2020. In comparison with all IVF procedures, 2.5% procedures were IVF with PGT, a highest percentage was in 2020 (3.8% of all procedures). The main indication for PGT was balanced chromosomal rearrangements (in 85.3% cases). In all 34 cases 515 oocytes were aspirated in total, 309 oocytes were fertilized, oocytes fertilization rate exceeded 60%. A normal diploid karyotype was found in 46 (16.8%) biopsied embryos. Out of all PGT procedures, 9 (26.5%) resulted in a clinical pregnancy. Six (66.7%) pregnancies were confirmed in 2019, and 3 (33.3%) – in 2020. Three (33.3%) pregnancies resulted in spontaneous abortion, 6 (66.7%) – in delivery.Conclusions: The implementation of PGT in VUHSK was successful. The most common indication for PGT was a reciprocal translocation. Oocytes fertilization rate exceeded 60%, a normal karyotype was found less than in one-fifth of biopsied embryos. A highest clinical pregnancy rate was achieved in 2019 when almost half of women conceived, which is probably related to the experience gained by the multidisciplinary team. This is the first study analyzing IVF with PGT in Lithuania, however, the results should be interpreted with caution due to a low number of total procedures performed.
Testosterone protects cardiomyocytes against hydrogen peroxide-induced aging by upregulating IGF1 and SIRT1 pathways
Authors: Yan Li , Nong Xiting , Deng Jizhao , Yang Guang
Published: August 2022

Objective

To investigate the role of IGF1 and SIRT1 pathways in protection of hydrogen peroxide (H2O2)-induced aging in H9c2 rat cardiomyocyte cells by testosterone.

Methods

The cells were treated with testosterone or up- or down-regulated for the IGF1 and SIRT1 genes and assessed for apoptosis, aging and expression of relevant genes.

Results

Aging was induced and the expression of SIRT1 and IGF1 was down-regulated after H2O2 treatment in H9c2 cells. The aging was attenuated in a dose-dependent manner after the cells were exposed to testosterone. Down-regulation of SIRT1 and IGF1expression was offset in the H2O2-treated cells co-treated with testosterone. Up- or down-regulation of IGF1 significantly reduced or increased senescence-associated beta-galactosidase (SA-β-gal) cells and the ROS level, respectively. In addition, SIRT1 expression was regulated by IGF1 expression. Down- or up-regulation of SIRT1 significantly decreased or increased the IGF1 levels, respectively. Furthermore, after IGF1 and SIRT1 knockdown, testosterone did not protect the cells from senescence. Testosterone, and overexpression of IGF1 and SIRT1 also up-regulated the expression of the fetal genes SERCA2 and MYH6 and down-regulated the expression of the ACTA1 and MYH7 genes.

Conclusions

Our data indicate that testosterone can attenuate cardiomyocyte aging induced by H2O2 and up-regulate SIRT1 and IGF1. The IGF1and SIRT1 pathway may be new targets to treat heart aging and heart failure.
Spectres of Today: The Fractures of History in Horse Money (2014)
Authors: Branco Sérgio Dias
Published: August 2022

It took Pedro Costa four feature films to get to Horse Money (Cavalo Dinheiro, 2014). In Down to Earth (Casa de Lava, 1994), a Portuguese nurse accompanies an immigrant worker in coma from Lisbon to his homeland, the Cape Verdean island of Fogo. Bones (Ossos, 1997), In Vanda’s Room (No Quarto da Vanda, 2000), and Colossal Youth (Juventude em Marcha, 2006) form a trilogy in which a group of Cape Verdean immigrants who lived in the Fontainhas slum becomes central. First travelling to Cape Verde, then getting to know and working with people from that Portuguese ex-colony on the outskirts of Lisbon, Costa’s films respond to the need for the voices of those who have been subordinated — the colonised, the discriminated, the exploited — to be articulated and valued. This article analyses the film style of Horse Money. It also pays attention to its thematic concerns and connections with other films directed by Costa, particularly those with Ventura, the central character in Horse Money. It argues that Horse Money tackles spectres haunting contemporary Portuguese society in a radical way, both politically and aesthetically. Its politics of representation are connected with the composition of a fractured history. These fractures emerge from the liberation of Cape Verde from Portuguese colonial domination as well as from the conflicting ruptures and continuities after the 1974 Carnation Revolution. In line with such an approach to these themes, the use of digital video, which has become common in Costa’s cinema since In Vanda’s Room, achieves hauntingly expressive qualities through mise-en-scène and image modulation.

The Dynamics of Localizing Home in Foreign Territories. Perspectives on Home-making and Media-related Practices among Migrant Households
Authors: Slettemeås Dag
Published: August 2022

This article explores perspectives and concepts for examining processes of migrant home-construction and meaning-making, and the role of media technologies in these dynamics. The household figures as the main locus of orientation, while theoretical perspectives on domestication and practice provide novel frames for understanding migrant everyday living and media relations, reaffirming a place-based analytical orientation. The justification for focusing on homes and local places, and on anchoring experiences in daily household activities and routines, is not to avoid aspects of distant connectivity, symbolic attachment and cultural identification to other spaces. Rather, the perspectives employed anchor these aspects in situated, place-based practices and orientations, and the analysis empirically grounds a multi-dimensional understanding of home-construction. In brief, the article argues that any apparent disconnection from place is still heavily entangled in place-based practices, contingencies, moralities and constraints. Implied in this reorientation is a suggested movement away from methodological nationalism towards everyday perceptions and practices, avoiding a bounded, essentialistic and conflated conception of identity, community and culture. The theoretical and empirical investigation suggests opening up the proposed conceptual apparatus in order to better encapsulate the complexity and multi-dimensionality of migrant everyday living.
Maghrebi Women in Spain: Family Roles and Media Consumption
Authors: Bailén Amparo Huertas , Suárez Yolanda Martínez
Published: August 2022

This article examines the process of adaptation of Maghrebi women in migratory contexts by analysing their media diet, placing a focus on women of Moroccan origin who reside in Spain. On the one hand, the cultural setting is considered as a symbolic space in which the foreign-origin population should feel interested and to which access should be facilitated; on the other hand, cultural identity is considered as something that is both flexible and dynamic. Given that the lives of these women are basically limited to the home and that their roles in the family are heavily influenced by gender, the question addressed is: to what extent does the condition of being wives and mothers affect their media diet? Concepts such as ‘cultural overburden’ (feminist theories) and ‘institutional mediation’ (cultural studies) underpin the theoretical framework. The results suggest that the consumption of Arabic-language media reflects the need to maintain an emotional tie to the culture of origin. In the host country, access to media is restricted due to the low level of technological equipment in the home and to claims that this is ‘good for the family’. However, the behaviour of teenagers approximates to that of a ‘bridge’ generation.
Online-offline strategies of urban movements against vacancies. The crowdsourcing platform Leerstandsmelder.de as a collective and critical mapping tool
Authors: Arnold Gregor
Published: August 2022

It is a paradox that in spite of growth of major cities due to migration and enormously increasing spatial-economic pressure, a large number of vacant and neglected properties can be found in German metropolitan areas. Urban movements are increasingly protesting against this development and call for an opening and a non-commercial use of these properties. This article broaches the issue and the meaning of digitized urban movements in regaining control of urban development processes by focusing on the opening and the usage of vacancies. More precisely, it deals with collective critical online mapping of vacancies. Urban movements use new media technologies like crowdsourcing platforms to promote counter-publicity and alternative views. Building on a case study of the German online mapping platform Leerstandsmelder.de and the urban collective Schnittstelle5 of the city of Mainz I assess to what extent urban movements may take advantage of the new digital possibilities to tackle the challenge of vacancies. The article examines how urban movements use geoweb and geo-referenced crowdsourcing services, and considers how such strategies may change both the acquisition and the usage of urban space.
Media Rituals in Eusébio’s Exequies
Authors: Mateus Samuel
Published: August 2022

While celebrating collective representation, the media can be seen as spaces of ritualization that are fundamental to the consolidation of wider social values.

In this paper we give an empirical frame to the concept of “media rituals” considering it as an entrenched symbolic practice that could be traceable in Eusébio’s exequies television broadcasting. Three sorts of media rituals are identified: rituals dealing with immediacy, rituals dealing with collective prominence and rituals dealing with the revelation of reality.

Each media ritual exemplifies how a space of comprehensive ritualization is erected. It is through this generalized and mediated ritualization that the idea of a major social occurrence is refreshed and worked through.
O futuro da imprensa portuguesa: há lugar para o Estado?
Authors: Silva Elsa Costa
Published: August 2022

Os jornais estão em declínio acentuado em Portugal, a nível de circulação e de receitas. Estilos de vida e tecnologia explicam a tendência que poderá, a curto ou médio prazo, levar ao desaparecimento dos títulos de informação nacional. Os jornais desempenham, contudo, funções únicas no campo mediático, o que levanta questões sobre o impacto desta tendência nas democracias. Crescentemente, tem sido apontado que a crise na imprensa escrita não pode ser resolvida apenas em contexto do mercado liberal e que há lugar para uma intervenção legítima dos Estados. Partindo da identificação e caracterização do desempenho dos principais grupos de media no sector da imprensa escrita, este artigo discute as medidas de apoio do Estado à imprensa portuguesa, destacando outros possíveis cenários de intervenção.
Mediação digital para a inovação territorial: um estudo de caso múltiplo em redes sociais digitais
Authors: Tymoshchuk Oksana , Almeida Ana Margarida , Ramos Fernando , Pedro Luis , Silva Paula Alexandra , Renó Denis
Published: August 2022

As redes sociais digitais são espaços infocomunicacionais contemporâneos que estão a influenciar o desenvolvimento social e económico dos territórios. No entanto, o papel das redes sociais digitais nos processos de inovação territorial de base comunitária ainda não foi suficientemente explorado, carecendo de aprofundamento dada a escassez de estudos científicos e de publicações sobre este tema. Neste artigo procura-se contribuir para a compreensão do papel das redes sociais digitais na promoção de cenários efetivos de inovação territorial nas áreas do Turismo e da Saúde e Bem-estar. Neste sentido, realizou-se um benchmarking do uso das redes sociais (Facebook, Twitter e Youtube) de iniciativas locais, na tentativa de identificar exemplos de boas práticas de utilização destas redes para a dinamização de projetos de inovação territorial. Embora as redes sociais selecionadas se distingam pelo número de seguidores e tenham diferentes níveis de envolvimento e colaboração entre os utilizadores, pudemos observar, neste levantamento de dados, os principais fatores motivadores para a participação das iniciativas estudadas. Pese embora a especificidade dos casos estudados, considera-se que o estudo apresenta um contributo para construir uma visão mais analítica sobre as práticas de gestão das redes sociais; os resultados alcançados poderão ser utilizados para extrair recomendações para a consolidação efetiva de estratégias que visam a promoção da capacidade de iniciativa das comunidades locais.
Femicides in native digital news outlets: greater and better coverage? A study of violence against women in the Spanish media
Authors: Liberia Vayá Irene , Zurbano-Berenguer Belén , Edo Aurora
Published: August 2022

This paper presents the main findings of a qualitative study of news on femicides appearing in leading native digital news outlets in Spain. The study focused on 267 news items published in five digital news outlets between 1 January and 31 December 2017. The selection of the news outlets was based on their readership numbers and whether or not their editorial lines adopted a gender or feminist perspective. In order to assess ethical quality, the tool designed by Zurbano-Berenguer and García-Gordillo (2017) was used. Based on this tool, the results indicate the following: (1) news about femicides is of medium quality; (2) native digital news outlets with a gender perspective offer better and higher quality coverage; and (3) the extent to which ethical recommendations are followed is still very patchy, thus calling for more in-depth multi-methodological analyses. These findings allow us to conclude that there is a need to conduct further qualitative research involving media professionals that helps us to understand why, despite the clear recommendations and rules established in media ethical codes, there are still considerable deficiencies in ethical quality and sensitivity when reporting on such a key issue for democratic society.
Perfiles profesionales en el periodismo político local en tiempos de redes sociales
Authors: Soler Susana Pérez , Sanz Josep Lluís Micó
Published: August 2022

Introducción: Este artículo explora los nuevos profesionales que las empresas periodísticas locales están incorporando en un ecosistema en el que las plataformas digitales, principalmente Google y Facebook, cada vez tienen mayor peso como canales de distribución de los contenidos. Metodología: El objeto de estudio, en el marco del periodismo político, son 12 medios de proximidad catalanes escogidos en función de criterios de diversidad mediática y distribución geográfica. Se han realizado entrevistas en profundidad semi-estructuradas a 24 profesionales, desde editores hasta redactores pasando por gestores de redes sociales. Resultados: Se demuestra que las empresas incorporan nuevos perfiles para el periodismo político. Se enumeran nueve nuevos perfiles profesionales; aunque sólo tres de ellos, por el momento, son perfiles que las empresas periodísticas están contratando. Conclusiones: Las tareas asociadas a la distribución de contenidos, más propias de los profesionales de las relaciones públicas, ahora también recaen en los periodistas.
Interés y participación política de los preuniversitarios madrileños en el nuevo escenario político
Authors: Aladro Vico Eva , Requeijo Rey Paula
Published: August 2022

Este artículo investiga el interés y la participación política de los preuniversitarios madrileños en el nuevo escenario político español. Se desarrolla una amplia revisión bibliográfica de estudios internacionales y nacionales. Se analizan también los resultados de una encuesta en la que participaron 250 preuniversitarios madrileños. Los resultados del estudio revelan que la valoración de los partidos y los líderes por parte de los preuniversitarios es muy baja. Sin embargo, el interés por la política y la valoración del voto son muy altos. Además, los mecanismos no convencionales de participación política como los movimientos sociales, las huelgas, las manifestaciones y las RRSS obtienen un importante apoyo. Los jóvenes se informan de política, sobre todo, a través de diarios digitales, televisiones y redes sociales. El trabajo concluye que los preuniversitarios madrileños tienen interés por la política pero sienten desafección hacia los partidos y sus líderes. El distanciamiento y rechazo se dirige al funcionamiento de la democracia, no a la democracia en sí misma. Es urgente renovar y regenerar las estructuras políticas convencionales para reconectar con este colectivo.
A publicitação do privado na era da pós-verdade: uma exploração às redes sociais dos líderes políticos portugueses
Authors: Barriga Antónia do Carmo
Published: August 2022

Em tempos de busca de popularidade, e num contexto de luta de audiências e de disputa eleitoral inextricável da espetacularização da informação, os media e os políticos alimentam uma ideia (porventura ilusória) de humanização e de proximidade com os cidadãos, recorrendo para tal à exposição (mediática) do quotidiano e da privacidade dos atores políticos. Sabemos que não é de hoje que as liturgias políticas democráticas envolvem a dimensão do entretenimento, ele precede mesmo o surgimento dos meios audiovisuais. Este texto interroga se a utilização das redes sociais pelos políticos altera ou mantém tais práticas. No âmbito da pesquisa aqui reportada pretendeu-se perceber qual a visibilidade que os líderes políticos portugueses dão à exposição de mensagens que evadem o discurso público e o debate político, partindo da análise da sua presença nas redes sociais. A análise efetuada tenta explorar se a postura dos políticos nos novos media, menos sujeita à coação dos media tradicionais e dos seus critérios, difere daquela que é habitualmente exibida nos media tradicionais, no que respeita à exposição de aspetos da sua vida privada. Foi neste sentido que se analisou o corpus empiricus constituído pela totalidade das publicações dos líderes dos partidos políticos portugueses, com assento parlamentar, à data, nas redes sociais Twitter, Facebook e Instagram, publicadas durante os três meses anteriores às eleições legislativas de 6 de outubro de 2019. Esta pesquisa foi também e ainda o mote, ou o pretexto, para uma abordagem mais ampla à privacidade na contemporaneidade e ao (s) modo (s) como ela hoje se entrelaça e intrinca com os novos media e com os sistemas automáticos.
Los marcos del compromiso: Framing y Engagement digital en la campaña electoral de España de 2015
Authors: A. Ballesteros-Herencia Carlos
Published: August 2022

Framing y engagement son dos planteamientos teóricos frecuentes en Ciencias Sociales en general y en Comunicación en particular, sin embargo, la interrelación de ambos en el mundo digital está comenzado a indagarse. Por ello, esta investigación estudió la implicación de los usuarios con los marcos informativos empleados por los seis principales partidos políticos españoles (PSOE, PP, Podemos, IU, UPyD y Ciudadanos) en sus páginas de Facebook, utilizando el estudio del caso de las elecciones generales de 2015. Se analizaron todos los mensajes publicados durante dos semanas de campaña electoral por estos seis partidos y sus candidatos, midiéndose el engagement mediante las variables Me gusta, Compartir y Comentar. Se detectó que no siempre los marcos más empleados por las formaciones políticas son los que mayor número de interacciones reciben por parte de los usuarios de las redes sociales. Así, el marco estratégico, si bien poco utilizado por los políticos, cuarto de un total de seis, fue el segundo con mayor nivel del engagement . Por el contrario, el marco temático, tercero más frecuente, sólo fue el quinto en implicación de los seguidores. Además, las tres variables indicadoras de engagement variaron en diferente proporción ante cada marco analizado.
Plataformas de online dating: dinâmicas de incorporação e integração numa lógica de domesticação
Authors: Sepúlveda Rita , Vieira Jorge
Published: August 2022

Entre o conjunto de aplicações disponíveis para smartphones as específicas de online dating têm sido alvo de atenção por parte da imprensa e da academia. Porém, este interesse não se traduziu numa tentativa de descrição e problematização de comportamentos no âmbito da domesticação das mesmas. Face a esta lacuna, este estudo tem como objetivo identificar e caracterizar padrões de uso em função da fase de incorporação e concluir face à integração das plataformas de online dating no quotidiano dos seus utilizadores. Para tal, recorreu-se a uma metodologia quantitativa através da aplicação de um questionário distribuído online e dirigido a utilizadores portugueses de plataformas de online dating (n=326). Foi realizada uma análise de correspondência múltipla (ACM) e uma análise de agrupamentos (clusters) que indiciou a existência de três perfis distintos. Os perfis diferenciaram-se em função da dimensão incorporação no âmbito da temporalidade (antiguidade, frequência e intensidade de uso) e da socialização (iniciativa no envio da primeira mensagem, contacto de perfis e rutura comunicacional sem motivo aparente), assim como em função da dimensão integração (partilha de contacto alternativo, procura de informação nas redes sociais online e partilha de perfis com outros). Tais características permitiram concluir que os perfis se distinguem em função da experiência e de uma utilização mais ou menos consolidada. Adicionalmente a distinção também reside na transposição das lógicas comunicacionais para o ecossistema dos media sociais mais alargado, evidenciando o dinamismo do processo de domesticação.
Citizen Facebook: The Strategic Communication of Local Power in Social Media
Authors: Martins João Carlos
Published: August 2022

Local power requires a differentiated communicational analysis with strategies appropriate to its context in the immediate scenario which social networks impose on those who engage in proximity governance. In this sense, this exploratory case study arises from an interest in communication as a tool for strategic and political operationalization, at the level of the preliminary diagnosis on digital communication within the Lisbon local government between November 2017 and May 2019. The objective has been to analyse digital data taken from the official Facebook pages of the 24 Local Councils and cross-referencing them with voter turnout data and, in a descriptive analysis of the information gathered, to arrive at an initial interpretation of the evolution of the performance and degree of involvement of electors and voters in digital municipal communication in Lisbon.
Twitter’s impact in building reputed hospital brands in USA
Authors: Aguerrebere Pablo Medina
Published: August 2022

Social media have become a strategic tool for hospitals interested in boosting their corporate communication and achieving several organizational objectives such as improving patient’s engagement or reinforcing their own corporate reputation. These platforms help hospitals adapt their communication strategies to a new context (new patients’ demands, increasing competition between health organizations, development of health technologies, etc.). This paper aims to analyse Twitter’s impact in branding initiatives led by hospitals. To do that, we carried out a literature review about corporate communication, branding and social media; and then, we analysed Twitter’s corporate profiles of the best US hospitals in the treatment of oncological diseases. This paper concludes that hospitals interested in effectively using Twitter as a corporate communication tool for branding initiatives need to carry out a strategic reflection before launching any initiative on this platform, improve Twitter’s integration with other social media platforms and mobile applications, and facilitate better collaborations between health professionals and communication experts.
All aboard?! Co-viewing with and within connected platforms in the Eurovision Song Contest
Authors: Pires Fernanda , Roig Antoni
Published: August 2022

Based on co-viewing and connected viewing literature (Authors, year), this article analyses connected co-viewing practices within and with the use of media platforms around a live television event, using the Eurovision Song Contest as a case study. This popular event has a long-running tradition which has fostered extensive use of different kinds of connected platforms, including an official app. Using a case study approach and focusing on the Spanish context, we have analysed connected co-viewing in three main platforms: Facebook (through unofficial groups), Twitter (through live conversation and hashtagging practices around the event) and by exploring the Eurovision official second screen app. The study indicates that: (1) co-viewing is mutually shaped by the affordances and interface features of the platforms, the viewers’ practices and uses given to these platforms; (2) co-viewing can be expanded by platforms when designed for collective use; (3) user-generated content and data production are central elements to enhance co-viewing when using connected platforms; (4) platform affordances can create digital spaces, which might channel the way co-viewers perform and enjoy this activity.
Democracia em risco? Explorando a contribuição do ciberjornalismo para o fenómeno do filtro-bolha
Authors: Machado Sara Monteiro
Published: August 2022

Nos últimos anos, a academia tem-se debruçado sobre o fenómeno do filtro-bolha, uma bolha informacional digital criada pelos algoritmos, onde o utilizador é exposto constantemente a conteúdos personalizados de acordo com o seu perfil, valores e interesses. Neste contexto, o jornalismo – pilar das sociedades democráticas – é usualmente retratado como a antítese do filtro-bolha, cujos efeitos nefastos para a liberdade e a democracia parecem ser consensuais. O que não tem sido suficientemente estudado, no entanto, é a eventual contribuição do jornalismo digital – o ciberjornalismo – para o fenómeno. De cariz exploratório, este artigo tem como objetivo abrir novas avenidas de investigação sobre o tema, utilizando para isso uma metodologia qualitativa, através de uma revisão da literatura aprofundada e de uma análise de dados secundários. Sugere-se que os novos modelos de negócio do ciberjornalismo – muito dependentes das grandes plataformas de tecnologia, dos anunciantes e da audiência – estão a contribuir largamente para o fenómeno do filtro-bolha. Tanto no âmbito da publicidade digital como no da atual aposta geral para um modelo de subscrições, verifica-se que as redações estão cada vez mais a recolher e analisar dados dos consumidores para personalizar a informação. Demonstra-se ainda que esta customização – da produção à distribuição de conteúdos – é vista de forma positiva, e até entusiasta, pelos média, sendo raras as vozes a refletir sobre o seu lado negativo. Conclui-se que o jornalismo pode assumir um papel relevante no combate às bolhas informacionais, tanto através da revisão dos seus modelos de negócio digitais como através da consciencialização dos indivíduos para o problema.
