'It’s not just Instagram models' : exploring the gendered political potential of young women’s Instagram use

With over one billion monthly users worldwide (Constine, 2018) and being embedded in the everyday lives of many young people, Instagram has become a common topic of discussion both in popular media and scholarly debates. As young women are amongst the predominant active users of Instagram (WeAreSocial, 2019) and the demographic stereotypically associated with online self-representation (Burns, 2015), Instagram carries an underlying gendered political potential. This is manifested through online political practices such as hashtag activism (Highfield, 2016), as well as through Instagram’s use of user-generated content to challenge existing politics of representation, broadening the scope of who is considered photographable (Tiidenberg, 2018). This article explores how this gendered political potential is understood by young women using Instagram. This research is based on 13 in-depth interviews with a theoretical sample of female ‘ordinary’ Instagram users (i.e., not celebrities or Insta-famous), aged 18–35. Our findings illustrate how the perception of political potential is grounded in the participants’ understanding of Instagram as an aesthetically-oriented platform (Manovich, 2017). Most participants recognised the potential for engaging in visibility politics (Whittier, 2017), representing a wider diversity of femininities often absent from popular media. However, this was seen as tempered by the co-existence of idealised beauty conventions and the politics of popularity within social media (Van Dijck & Poell, 2013). Furthermore, this political potential is accompanied by the possibility of receiving backlash or being dismissed as a slacktivist (Glenn, 2015). As Instagram becomes a central part of contemporary visual cultures, this article seeks to critically explore the nuanced ways in which young women’s everyday experiences of Instagram intersect with broader cultural and political questions of gender representation

Identidades em Fluxo: a auto-representação fotográfica e o caso prático do Instagram

A fotografia tem sido utilizada desde a sua génese como uma ferramenta performativa para a autorepresentação identitária, servindo para criar reflexivamente uma imagem idealizada do self, através de mecanismos retóricos que lhe são próprios. Seja através da representação directa ou não, a fotografia quando em contextos comunicacionais e narrativos oferece sempre uma construção identitária do criador destas imagens, ao tornar visível as suas escolhas de estilo de vida. A memória desempenha também um importante papel nas práticas fotográficas, permitindo que estas imagens inertes participem na criação de narrativas pessoais e salvando das incertezas da mente humana os momentos fugazes da nossa existência. Visto como mais objectiva, a fotografia funciona prova de algo ou da existência de alguém, parecendo residir nesta capacidade apodítica o seu maior valor, a despeito do seu inevitável enviesamento ideológico. A fotografia é também forçosamente um artefacto social, obedecendo a regras e convenções que lhe são implícitas e que moldam-na, assim como à leitura que os outros farão dela. Com a introdução da fotografia digital estas práticas massificaram-se e tornaram-se mais baratas, portáteis e integradas no dia-a-dia, notando-se uma aceleração quer na criação quer na visualização de imagens e uma maior abertura para a experimentação, aceitando o mundano e o banal como possíveis objectos de interesse e dando-lhes um destaque até então impensável. As novas redes sociais, em especial o Instagram, vieram alargar consideravelmente o número de fotógrafos e expandir as possibilidades da fotografia vernacular, tornando necessário reavaliar estas questões à luz das novas práticas fotográficas que este instaurou

Between the mundane and the political : women’s self-representations on Instagram

Women’s self-representation on Instagram is often discussed in popular media in polarizing terms, as either an empowering practice or as boring and mundane. However, the political and the mundane are inevitably interwoven. This article grounds the discussions on how “the political” can be expressed through mundane Instagram practices on the analysis of individual self-representations of “ordinary” Instagram users (i.e., not celebrities or Insta-famous users). This research is based on a qualitative textual analysis of a sample of 77 randomly selected female Instagram users, ages 18–35, analyzing their photographic self-representations and its surrounding textual context—captions, comments, and likes. It explores how Instagram can broaden the scope of who and what is considered photographable, allowing for the representation of a wider variety of women and femininities underrepresented in popular media, and how this has the potential to upend hegemonic hierarchies of visibility. Following an Instagrammable aesthetic, these self-representations often take place in mundane contexts, as the photographable becomes extended to overlooked, yet essential, aspects of everyday life. It is in the context of these everyday self-representation practices that tangentially political themes become embedded, appearing in brief and often passing mentions that express self-worth, celebrate marginalized identities, or proclaim personal agency

Negative symptoms mediate the relationship between social cognition and functioning in schizophrenia: a pilot study

In spite of significant advances in pharmacological and psychological treatments, schizophrenia still ranks among the leading causes of disability worldwide. People suffering from schizophrenia have significant impairment in major areas of everyday life, such as interpersonal relationships, work or school and even self-care. Enhancing the understanding of factors that hinder real-life functioning is therefore crucial for translating delivered care into more positive outcomes. Social cognition, defined as the mental operations that underlie social interactions, including perceiving, interpreting, and generating responses to the intentions, dispositions, and behaviors of others, has been implicated in impaired functioning. It is typically broken down into four domains: emotion processing, social perception, attributional bias and theory of mind. Negative symptoms have also been associated with patients' functional outcome; although generally conceptualized as a unitary construct, the most recent literature suggests that these symptoms are heterogeneous and include at least two factors: amotivation and diminished emotional expression. The aim of this study was to analyze the relationships between negative symptoms, social cognition and real-life functioning in people with schizophrenia. Methods: 12 patients with diagnosis of schizophrenia according to ICD-10 criteria were assessed cross-sectionally regarding relevant dimensions to our study: general psychopathology (Positive and Negative Syndrome Scale), social cognition (Face and Emotion Identification Test, Schema Component Sequencing Test - Revised, Social Perception Scale, Ambiguous Intentions and Hostility Questionnaire, Reading the Mind in The Eyes Test), negative symptoms (Clinical Assessment Interview for Negative Symptoms – CAINS) and general functioning (Personal and Social Performance scale – PSP). Spearman correlations were examined and regression and mediation models (Preacher and Hayes bootstrapping methodology) were performed. Results: In our preliminary results, emotion processing was the only social cognition dimension significantly correlated with functioning (rS = .87) and negative symptoms measured by the CAINS: rS = -.78 with amotivation; -.70 with diminished emotional expression and -.78 with total CAINS score (all Po.01). Both amotivation and diminished emotional expression, as well as negative symptoms as a whole, correlated with functioning (rS4.80, Po.01). Emotion processing was a significant predictor of amotivation, diminished emotional expression and total CAINS score (all Beta4-.65, p o.05). Both emotion processing (Beta = .71, P = 0.3) and amotivation (Beta = -.84, P = 0.001) were significant predictors of functioning. Finally, amotivation was found to be a partial mediator of the relationship between emotion processing and functioning (BCA 95% CI = .196 - 7.559). Discussion: Our results are in partial agreement with previous studies suggesting that emotional processing is the most relevant dimension of social cognition to everyday functioning, despite a possible contribution of theory of mind for such impairment in patients with schizophrenia. Regarding negative symptoms, amotivation seems to be the dimension of most relevance to functioning. Altogether, negative symptoms seem to be driven by social cognition deficits and, at least partially, negative symptoms may play a role in the deleterious impact of impaired social cognition on functional outcome. The complexity of the crosstalk between negative symptoms, social cognition and functioning will be better addressed in ongoing studies, as a greater understanding of underlying mechanisms is critical to development of effective treatments

Previous research shows a correlation between the levels of vitamin D in patients infected with SARS-CoV-2 and the degree of disease severity. This work investigates the impact of the genetic background related to vitamin D pathways on COVID-19 severity. For the first time, the Portuguese population was characterized regarding the prevalence of high impact variants in genes associated with the vitamin D pathways. This study enrolled 517 patients admitted to two tertiary Portuguese hospitals. The serum concentration of 25 (OH)D, was measured in the hospital at the time of patient admission. Genetic variants, 18 variants, in the genes AMDHD1, CYP2R1, CYP24A1, DHCR7, GC, SEC23A, and VDR were analysed. The results show that polymorphisms in the vitamin D binding protein encoded by the GC gene are related to the infection severity (p = 0.005). There is an association between vitamin D polygenic risk score and the serum concentration of 25 (OH)D (p = 0.04). There is an association between 25 (OH)D levels and the survival and fatal outcomes (p = 1.5e-4). The Portuguese population has a higher prevalence of the DHCR7 RS12785878 variant when compared with its prevalence in the European population (19% versus 10%). This study shows a genetic susceptibility for vitamin D deficiency that might explain higher severity degrees in COVID-19 patients. These results reinforce the relevance of personalized strategies in the context of viral diseases.This project was supported by the “Fundação para a Ciência e Tecnologia”, program “Research 4 Covid-19 Apoio especial a projetos de implementação rápida para soluções inovadoras de resposta à pandemia de COVID-19”.

Influenza seroprotection correlates with predominant circulating viruses during 2014/15 and 2015/16 seasons in Portugal

Rede Portuguesa de Laboratórios para o Diagnóstico da GripeBACKGROUND: Population immune profile for influenza is highly affected by circulating influenza viruses, thus changing the risk of infection for influenza. This study aims to assess influenza immunity in the Portuguese population by age groups, during 2014 and 2015 and establish a relationship between seroprotection and circulating influenza viruses in 2014/15 and 2015/16 seasons. METHODS: Two cross-sectional studies were developed based on a convenience serum sample collected in June 2014 (n=626) and July 2015 (n=675) in hospitals from mainland and Azores and Madeira.Serums equally represent all age groups. Antibody titers were evaluated by HI assay for strains recommended for seasonal influenza vaccine northern hemisphere,2014/15 and 2015/2016. Seroprevalences were estimated for each strain by age group and the association with seasonal cumulative influenza-like illness (ILI) rates for influenza virus during both seasons was analised. RESULTS: In June 2014 the highest seroprotection was observed for influenza A(H3) (39.0%; 95% CI: 36.2-43.8%) and A(H1)pdm09 (29.7; 95% CI: 26.3-33.4%), with higher levels in children 5-14 years old. In 2014/2015 a dominant circulation of influenza B/Yamagata was observed with high incidence rates in individuals under 65 years old, the ones that had lower seroprotection. Although before the start of the season high protection for A(H3) was observed, the circulation of the new drift A(H3) strains had gained an immunological advantage,in accordance with A(H3) elevated incidence rates observed during 2014/15. In July 2015 the highest seroprotection was observed for influenza B/ Yamagata (55.1%; 95% CI: 51.4-58.9%), 2.4 times the estimated 2014.This increase was even more pronounced in younger (≤ 4 years old), 6.3 times increase in 2015.This fact is in agreement with the predominant influenza B virus detected and the high ILI incidence rate observed in children during 2014/2015 epidemic. Seroprotection levels for influenza A in July 2015 were not significantly different from 2014.During 2015/16 season, influenza A(H1N1)pdm09 was predominant, with high incidence rate in < 65 year old. Influenza B/Victoria lineage,although detected at low levels increased in frequency, in agreement with the lowest level of seroprotection detected in the general population before the start of 2015/2016 season (21.8%; 95% CI: 18.7-24.0%). CONCLUSIONS There was a correlation between virus circulation, incidence rates for each age group and the previous seroprotection for seasonal influenza viruses.Our study highlights the value of measuring the serological profile for influenza to establishe risk groups for infection for which an increase preventive measures, including vaccination, should be fostered.info:eu-repo/semantics/publishedVersio
