Beyond the TV borders: Second screen as a tool for audience engagement
The growing popularity of mobile connected devices has transformed the way TV content is conceived and consumed. Interacting with these devices while watching TV is a trending behaviour that represents a challenge for the TV industry as this interaction often distracts viewers from the TV content. Consumers use the second screen to retrieve further information about narratives, characters, purchasing goods and researching on products and services advertised. In a scenario of systematic live and linear TV audience erosion and ad-skipping broadcasters, marketers and producers are continuously looking for new ways to leverage different media strategies to keep TV viewers engaged with the primary content, promoting consumers’ loyalty and generating more revenue flows. In this paper, a set of second screen cases was selected to ground a reflection on how second screen solutions may be applied to foster the viewer and consumer engagement
How society’s negative view of videogames can discourage brands from sponsoring eSports
The purpose of this research was to identify the main motives that contribute to society’s
negative view of videogames and that present a risk to the eSports sponsors’ image. To achieve
this, an exploratory, qualitative, and integrative literature review was conducted. According to
the theoretical data, there are four main reasons why society has a negative perception of
videogames. It is commonly believed that: (1) gaming is an unproductive activity, (2) violent
videogames incite aggressive behaviors, (3) videogames lead to gaming-addiction, and (4)
eSports lead to eSports-related gambling addiction. However, while the literature presents
convincing evidence that gaming can create addiction and that eSports can promote gambling
addiction, there is no conclusive evidence to assume that violent videogames lead to
aggressiveness and there is evidence showing that playing videogames can be a productive
activity. Nevertheless, these four beliefs are a threat to the eSports sponsors’ image and may
lead them to cancel their existing sponsorships or lead other brands to not want to sponsor
eSports to prevent being associated with these negative notions. This research will help expand
the minor literature on eSports sponsorships and advance the knowledge of why some eSports
sponsorships are terminated and why some brands may be reluctant to sponsor eSports.info:eu-repo/semantics/publishedVersio
CRP polymorphisms and chronic kidney disease in the third national health and nutrition examination survey
<p>Abstract</p> <p>Background</p> <p><it>CRP </it>gene polymorphisms are associated with serum C-reactive protein concentrations and may play a role in chronic kidney disease (CKD) progression. We recently reported an association between the gene variant rs2808630 and CKD progression in African Americans with hypertensive kidney disease. This association has not been studied in other ethnic groups.</p> <p>Methods</p> <p>We used data from 5955 participants from Phase 2 of The Third National Health and Nutrition Examination Survey (1991-1994) to study the association between <it>CRP </it>polymorphisms and CKD prevalence in a population-based sample. The primary outcome was CKD defined as estimated glomerular filtration rate (eGFR) <60 ml/min or the presence of albuminuria. Secondary outcomes were the presence of albuminuria (any degree) and continuous eGFR. Six single nucleotide polymorphisms (SNPs) from the <it>CRP </it>gene, rs2808630, rs1205, rs3093066, rs1417938, rs3093058, and rs1800947, were evaluated.</p> <p>Results</p> <p><it>CRP </it>rs2808630 AG compared to the referent AA genotype was associated with CKD in non-Hispanic blacks (n = 1649, 293 of whom had CKD) with an adjusted odds ratio (OR) of 3.09 (95% CI 1.65-5.8; p = 0.001). For the secondary outcomes, rs2808630 AG compared to the referent AA genotype was associated with albuminuria with an adjusted OR of 3.07 (95% CI 1.59-5.94; p = 0.002), however not with eGFR. There was no association between the SNPs and CKD, albuminuria or eGFR in non-Hispanic whites or Mexicans Americans.</p> <p>Conclusions</p> <p>In this cross-sectional study, the 3' flanking <it>CRP </it>gene variant rs2808630 was associated with CKD, mainly through its association with albuminuria in the non-Hispanic blacks. Despite not finding an association with eGFR, our results support our previous study demonstrating an association between <it>CRP </it>gene variant rs2808630 and CKD progression in a longitudinal cohort of African American with hypertensive kidney disease.</p
Transgenic technologies to induce sterility
The last few years have witnessed a considerable expansion in the number of tools available to perform molecular and genetic studies on the genome of Anopheles mosquitoes, the vectors of human malaria. As a consequence, knowledge of aspects of the biology of mosquitoes, such as immunity, reproduction and behaviour, that are relevant to their ability to transmit disease is rapidly increasing, and could be translated into concrete benefits for malaria control strategies. Amongst the most important scientific advances, the development of transgenic technologies for Anopheles mosquitoes provides a crucial opportunity to improve current vector control measures or design novel ones. In particular, the use of genetic modification of the mosquito genome could provide for a more effective deployment of the sterile insect technique (SIT) against vector populations in the field. Currently, SIT relies on the release of radiation sterilized males, which compete with wild males for mating with wild females. The induction of sterility in males through the genetic manipulation of the mosquito genome, already achieved in a number of other insect species, could eliminate the need for radiation and increase the efficiency of SIT-based strategies. This paper provides an overview of the mechanisms already in use for inducing sterility by transgenesis in Drosophila and other insects, and speculates on possible ways to apply similar approaches to Anopheles mosquitoes

Genetic approaches to human renal agenesis/hypoplasia and dysplasia
Congenital abnormalities of the kidney and urinary tract are frequently observed in children and represent a significant cause of morbidity and mortality. These conditions are phenotypically variable, often affecting several segments of the urinary tract simultaneously, making clinical classification and diagnosis difficult. Renal agenesis/hypoplasia and dysplasia account for a significant portion of these anomalies, and a genetic contribution to its cause is being increasingly recognized. Nevertheless, overlap between diseases and challenges in clinical diagnosis complicate studies attempting to discover new genes underlying this anomaly. Most of the insights in kidney development derive from studies in mouse models or from rare, syndromic forms of human developmental disorders of the kidney and urinary tract. The genes implicated have been shown to regulate the reciprocal induction between the ureteric bud and the metanephric mesenchyme. Strategies to find genes causing renal agenesis/hypoplasia and dysplasia vary depending on the characteristics of the study population available. The approaches range from candidate gene association or resequencing studies to traditional linkage studies, using outbred pedigrees or genetic isolates, to search for structural variation in the genome. Each of these strategies has advantages and pitfalls and some have led to significant discoveries in human disease. However, renal agenesis/hypoplasia and dysplasia still represents a challenge, both for the clinicians who attempt a precise diagnosis and for the geneticist who tries to unravel the genetic basis, and a better classification requires molecular definition to be retrospectively improved. The goal appears to be feasible with the large multicentric collaborative groups that share the same objectives and resources

Toward a typology of young produsers: teenagers’ transmedia skills, media production, and narrative and aesthetic appreciation
Based on the qualitative analysis of data from workshops and interviews with teenagers from eight countries, this article aims to determine the degrees of productive, narrative, and aesthetic knowledge that teenagers put into practice when they create their media contents. From a theoretical framework that links teens, informal learning environments, and participatory cultures, the findings point toward three types of teenage produsers: casual, aspirational, and expert. Each type is representative of different aspects of production in terms of the types of media contents produced; the planning of the production process; the application of narrative and aesthetic values when creating; and the motivations behind the production. The study concludes with an invitation to rethink what participatory culture means in the light of teenagers’ production practices.This work has received funding from the European Union’s Horizon 2020 Framework Programme for Research and Innovation Actions under Grant Agreement Number 645238.New media & society. 2018 September 7: 18 p
