Yin-yang genetics, or the HSD deCODE controversy

Iceland has attracted world-wide attention because of a controversy surrounding the Icelandic Health Sector Database Act of 1998 and the genomics company deCODE Genetics. The controversy concerns limits to state power, bioethics and regulation of research, and civil liberties. Understanding it necessitates paying attention to the yin-yang-like character of deCODE; it is international or Icelandic, what is the relation between the HSD and deCODE, will the HSD engulf the Icelandic nation as a whole?     

Gendered genetics in Iceland

The integration of Iceland's phenotype and genotype, by bringing together the medical records, genealogies and genetic data by the commercial firm deCODE has been one of the most studied and controversial cases of the new pharmacogenomics. This paper explores the differences between the concerns and conceptualizations of women and men in debating this biomedical innovation.     

Genomics research in the UK—the social science agenda

Abstract

We sketch the development of UK genetics and genomics research, and emphasize the UK's key role in the international genetics and genomics research community. We highlight in particular the part played by the UK's Research Councils and other funders. With the move from genomics to post-genomics research, the field is diversifying, and interdisciplinarity becomes increasingly important, as traditional disciplinary boundaries become blurred, or break down, in the face of newly emerging sciences. We consider the changing nature of health and ill health in the developed and developing world, and questions about the complex nature of the relationships between genes and the environment, and their future implications for human health and human populations. We describe the ESRC's activities, stressing the importance of both the social, ethical and legal issues raised by these emerging disciplines, and of public engagement. Finally, we link the data handling and analysis issues raised by these emerging sciences, with other new research areas, in particular the UK's e-Science programme.     

Beyond the genome: Reconstituting the new genetics

The mapping and sequencing of the human genome has been the 'Holy Grail' of the new genetics, and its publication marks a turning point in the development of modern biotechnology. However, the question remains: what has been the impact of this discovery on how biotechnology develops in science, and in society at large? Using concepts developed in the social studies of science and technology, the paper begins by rehearsing the historical development of the Human Genome Project (HGP), and suggests that its translation into genomics has been achieved through a process of 'black-boxing' to ensure stabilization. It continues by exploring the extent to which the move to genomics is part of a paradigm shift in biotechnology resulting from the conceptual and organizational changes that have occurred following the completion of HGP. The discussion then focuses on whether genomics can be seen as part of the development of socially robust knowledge in late modernity. The paper suggests that there is strong evidence that a transformation is indeed taking place. It concludes by sketching a social scientific agenda for investigating the reconstitution of the new genetics in a post-genomic era using a 'situated' analytic approach based on an understanding of techno-scientific change as both emergent and contingent.     

Managing the boundaries between maverick cloners and mainstream scientists: the life cycle of a news event in a contested field

Abstract

In January 2004, the ‘maverick cloner’, Dr Panos Zavos called a press conference in London to announce that he had implanted a freshly cloned human embryo in the womb of an infertile woman. Reports of this press conference gained prominent coverage in the national newspapers the following day and led television bulletins that evening. This article discusses the ways in which expertise was claimed by or attributed to Dr Zavos and other key media sources. It argues that three key boundaries were demarcated in the coverage as journalists framed the stories in terms provided by Zavos's antagonists, ‘mainstream scientists’. It also discusses the engagement in tactics of news management by an organised grouping of UK scientists who attempted to shape the terrain of news coverage on the subject of cloning. The question of the extent to which interested scientists should be able to set the terms of media debate is explored.     

Effect of cell culture media on extracellular vesicle secretion from mesenchymal stromal cells and neurons

BackgroundExtracellular vesicles (EVs) secreted by neuronal cells in vitro have promising therapeutic potential for brain diseases. Optimization of cell culture conditions and methodologies for high-yield isolation of EVs for preclinical and clinical applications, however, remains a challenge.ObjectiveTo probe the cell culture conditions required for optimal EV secretion by human-derived neuronal cells.MethodologyFirst, we optimized the EV purification protocol using human mesenchymal stromal cell (MSC) cultures. Next, we compared the effects of different variables in human pluripotent stem cell (hPSC)-derived neuronal cultures on EV secretion. EVs were isolated from cell conditioned media (CCM) and control media with no cells (NCC) using ultrafiltration combined with size-exclusion chromatography (SEC). The hPSC neurons were cultured in 2 different media from which EVs were collected at 2 maturation time-points (days 46 and 60). Stimulation with 25 mM KCl was also evaluated as an activator of EV secretion by neurons. The collected SEC fractions were analyzed by nanoparticle tracking analysis (NTA), protein concentration assay, and blinded transmission electron microscopy (TEM).ResultsA peak in cup-shaped particles was observed in SEC fractions 7–10 of MSC samples, but not corresponding media controls, indicating successful isolation of EVs. Culture medium had no significant effect on EV yield. The EV yield of the samples did not differ significantly according to the culture media used or the cell maturation time-points. Stimulation of neurons with KCl for 3 h reduced rather than increased the EV yield.ConclusionsWe demonstrated successful EV isolation from MSC and neuronal cells using an ultrafiltration-SEC method. The EV yield from MSC and neuronal cultures exhibited a large batch effect, apparently related to the culture media used, highlighting the importance of including NCC as a negative control in all cell culture experiments.

Consistency of financial interest disclosures in the biomedical literature: the case of coronary stents

Background

Disclosure of authors'' financial interests has been proposed as a strategy for protecting the integrity of the biomedical literature. We examined whether authors'' financial interests were disclosed consistently in articles on coronary stents published in 2006.

Methodology/Principal Findings

We searched PubMed for English-language articles published in 2006 that provided evidence or guidance regarding the use of coronary artery stents. We recorded article characteristics, including information about authors'' financial disclosures. The main outcome measures were the prevalence, nature, and consistency of financial disclosures. There were 746 articles, 2985 authors, and 135 journals in the database. Eighty-three percent of the articles did not contain disclosure statements for any author (including declarations of no interests). Only 6% of authors had an article with a disclosure statement. In comparisons between articles by the same author, the types of disagreement were as follows: no disclosure statements vs declarations of no interests (64%); specific disclosures vs no disclosure statements (34%); and specific disclosures vs declarations of no interests (2%). Among the 75 authors who disclosed at least 1 relationship with an organization, there were 2 cases (3%) in which the organization was disclosed in every article the author wrote.

Conclusions/Significance

In the rare instances when financial interests were disclosed, they were not disclosed consistently, suggesting that there are problems with transparency in an area of the literature that has important implications for patient care. Our findings suggest that the inconsistencies we observed are due to both the policies of journals and the behavior of some authors.     

How an Egalitarian Polity Structures Tourism and Restructures Itself Around It

ABSTRACT

Korowai of Papua, Indonesia, are famous in tourism and mass media circles for their ‘tree houses’, and for other ways they match globally circulating stereotypes of primitive humanity. This article examines how tourism intersects with Korowai egalitarian politics. Korowai spatial dispersion and concern with equality mean that tourists' visits to the land of certain people and not others is politically sensitive. I describe new forms of differentiation arising around tourism, such as emergence of clans specializing in hosting tour groups, and of individual Korowai specializing as tourism mediators. Across these and other areas, what is most striking is how Korowai people's egalitarian political sensibilities have fostered complex forms of interlocal cooperation around tourist visits, innovated and agreed upon in a decentralized manner. This case illustrates a broader pattern that intersocietal articulations are often mediated by the social organization of difference and heterogeneity in people's home locations.     

Proper insertion and topogenesis of membrane proteins in the ER depend on Sec63

BackgroundIn eukaryotic cells, biogenesis of proteins destined to the secretory pathway begins from the cytosol. Nascent chains are either co-translationally or post-translationally targeted to the endoplasmic reticulum (ER) and translocated across the membrane through the Sec61 complex. For the post-translational translocation, the Sec62/Sec63 complex is additionally required. Sec63, however, is also shown to mediate co-translational translocation of a subset of proteins, the types and characteristics of proteins that Sec63 mediates in translocation still await to be defined.MethodsTo overview the types of proteins that require Sec63 for the ER translocation, we prepared Sec63 mutant lacking the first 39 residues (Sec63_ΔN39) in yeast and assessed initial translocation efficiencies of diverse types of precursors in the sec63_ΔN39 strain by a 5 min metabolic labeling. By employing Blue-Native gel electrophoresis (BN-PAGE), stability of the SEC complex (Sec61 plus Sec62/Sec63 complexes) isolated from cells carrying the Sec63_ΔN39 mutant was examined.ResultsAmong the various translocation precursors tested, we found that proper sorting of single- and double-pass membrane proteins was severely impaired in addition to post-translational translocation precursor in the sec63_ΔN39 mutant strain. Stability of the SEC complex was compromised upon deletion of the N-terminal 39 residues.ConclusionsThe N-terminus of Sec63 is important for stability of the SEC complex and Sec63 is required for proper sorting of membrane proteins in vivo.General significanceSec63 is essential on insertion of membrane proteins.     

Clinical Practice Guidelines and Consensus Statements in Oncology – An Assessment of Their Methodological Quality

BackgroundConsensus statements and clinical practice guidelines are widely available for enhancing the care of cancer patients. Despite subtle differences in their definition and purpose, these terms are often used interchangeably. We systematically assessed the methodological quality of consensus statements and clinical practice guidelines published in three commonly read, geographically diverse, cancer-specific journals. Methods Consensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine’s standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents.MethodsConsensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine''s standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents.FindingsThirty-four consensus statements and 67 clinical practice guidelines were evaluated. The rigour of development score for consensus statements over the three journals was 32% lower than that of clinical practice guidelines. The editorial independence score was 15% lower for consensus statements than clinical practice guidelines. One journal scored consistently lower than the others over both domains. No journals adhered to all the items related to the transparency of document development. One journal’s consensus statements endorsed a product made by the sponsoring pharmaceutical company in 64% of cases.ConclusionGuidance documents are an essential part of oncology care and should be subjected to a rigorous and validated development process. Consensus statements had lower methodological quality than clinical practice guidelines using AGREE II. At a minimum, journals should ensure that that all consensus statements and clinical practice guidelines adhere to AGREE II criteria. Journals should consider explicitly requiring guidelines to declare pharmaceutical company sponsorship and to identify the sponsor’s product to enhance transparency.     

Getting integration right? Media transnationalism and domopolitics in Ireland

Abstract

This article examines the transnational media environments and experiences of Nigerian and Chinese nationals living in Ireland. It theorizes empirical research in the context of the mode of integration governance developed in the Republic of Ireland during a period of significant in-migration. Building on a theory of domopolitics, it suggests that Ireland's short-lived integration regime deployed culture and interculturalism as resources for the self-governing integration of all foreign nationals, while developing a system of civic stratification designed to limit claims to citizenship and social and economic rights. It examines the concomitant development of public service media policies in this context. Drawing on recent discussions of contrapuntal media readings, the article argues that transnational media experience refracts the lived tensions inherent in the disjuncture between the possibilities of cultural participation and the constraints of socio-political containment.     

Purposefully poetic

ABSTRACT

Arts education has no firm place in Hawaii's public school system. Even the Board of Education plan and the State Department of Education's plans differ in how they refer to and make recommendations about the place or purpose of arts education. This article reviews examples of competing policy to suggest how arts-integrated style teaching could both bridge the gap and extend strategic goals. The article provides examples of how drama-integrated style teaching has positive social and academic benefits for English language learners that specifically build their self-efficacy, helping such students to become better learners. Using these examples, the article suggests potential strategic plan revisions.     

The Impact of Boundary Spanning Scholarly Publications and Patents

Background

Human knowledge and innovation are recorded in two media: scholarly publication and patents. These records not only document a new scientific insight or new method developed, but they also carefully cite prior work upon which the innovation is built.

Methodology

We quantify the impact of information flow across fields using two large citation dataset: one spanning over a century of scholarly work in the natural sciences, social sciences and humanities, and second spanning a quarter century of United States patents.

Conclusions

We find that a publication''s citing across disciplines is tied to its subsequent impact. In the case of patents and natural science publications, those that are cited at least once are cited slightly more when they draw on research outside of their area. In contrast, in the social sciences, citing within one''s own field tends to be positively correlated with impact.     

Exploring the post-genomic world: differing explanatory and manipulatory functions of post-genomic sciences

Richard Lewontin proposed that the ability of a scientific field to create a narrative for public understanding garners it social relevance. This article applies Lewontin's conceptual framework of the functions of science (manipulatory and explanatory) to compare and explain the current differences in perceived societal relevance of genetics/genomics and proteomics. We provide three examples to illustrate the social relevance and strong cultural narrative of genetics/genomics for which no counterpart exists for proteomics. We argue that the major difference between genetics/genomics and proteomics is that genomics has a strong explanatory function, due to the strong cultural narrative of heredity. Based on qualitative interviews and observations of proteomics conferences, we suggest that the nature of proteins, lack of public understanding, and theoretical complexity exacerbates this difference for proteomics. Lewontin's framework suggests that social scientists may find that omics sciences affect social relations in different ways than past analyses of genetics.     

Mainstreaming Sex and Gender Analysis in Public Health Genomics

BackgroundThe integration of genome-based knowledge into public health or public health genomics (PHG) aims to contribute to disease prevention, health promotion, and risk reduction associated with genetic disease susceptibility. Men and women differ, for instance, in susceptibilities for heart disease, obesity, or depression due to biologic (sex) and sociocultural (gender) factors and their interaction. Genome-based knowledge is rapidly increasing, but sex and gender issues are often not explored.ObjectiveTo explore the implications of a sex and gender analysis for PHG.MethodsWe explore genome-based knowledge in relation to sex and gender aspects using depression as an example, gender equality, and the intersection of sex and gender with other social stratifiers such as ethnic background or socioeconomic status.ResultsWe advocate a sex- and gender-sensitive genomics research agenda alongside studies that provide sex-disaggregated data rather than controls based on sex. Such a research agenda is needed to guide research on how genomics is understood and perceived by men and women across groups, and for the equitable and responsible translation of such knowledge into the public health domain.ConclusionsIncluding sex and gender analysis in PHG research will not only shed more light on phenomena such as diseases with a higher prevalence in either men or women, but will ultimately lead to gendered innovations by way of exploring how gendered and cultural environments increase or safeguard genetic predispositions.     

Effect of social media use on learning,social interactions,and sleep duration among university students

BackgroundSocial networking sites are widely used by university students. This study investigated the purposes for which social networking sites are used and their effects on learning, social interaction, and sleep duration.Material and methodsA cross-sectional study was conducted among 300, 17–29-year-old female students at Prince Sattam bin Abdul Aziz University. A questionnaire was used to collect data. Chi-squared (Fisher’s exact test) test was used to analyze the data.ResultsThe results showed that 97% of the students used social media applications. Only 1% of them used social media for academic purposes. Whereas 35% of them used these platforms to chat with others, 43% of them browsed these sites to pass time. Moreover, 57% of them were addicted to social media. Additionally, 52% of them reported that social media use had affected their learning activities, 66% of them felt more drawn toward social media than toward academic activities, and 74% of them spent their free time on social media platforms. The most popular applications (i.e., based on usage) were Snapchat (45%), Instagram (22%), Twitter (18%), and WhatsApp (7%). Further, 46% and 39% of them reported going to bed between 11 pm and 12 am and between 1 am and 2 am, respectively. Finally, 68% of them attributed their delayed bedtime to social media use, and 59% of them reported that social media had affected their social interactions.ConclusionsA majority of the participants reported prolonged use of social networking sites for nonacademic purposes. These habitual behaviors can distract students from their academic work, adversely affect their academic performance, social interactions, and sleep duration, and lead to a sedentary lifestyle and physical inactivity, which in turn can render them vulnerable to non-communicable diseases and mental health problems.     

The Gran Poder Parade and the Social Movement of the Aymara Middle Class: A Video Essay

The parade for the patron saint of the parish of Gran Poder is the largest city-wide folklore event in La Paz, Bolivia, in which tens of thousands of indigenous Aymara and mestizo residents of the city participate in dances that tie them to the nation's indigenous past. The sequences of images discussed in this article focus on a dance fraternity composed of members of the prosperous urban Aymara middle class (or cholos ) who use their indigenous costumes and dance movements as vehicles in which they enter and display their modernity. Using harshly exaggerated masks that relate social subordination to racial difference, the performance of the Morenada by today's well-to-do Aymaras revisits the cultural marginalization and hardship they experienced in their own migration to La Paz from the rural countryside. Wearing a series of expensive outfits and ostentatious costumes, these dancers vividly flaunt their distinction from the Western-mestizo middle class, and its signs of well-being.     

The Impact of Guide Dogs on the Identity of People with Visual Impairments

ABSTRACT

This paper explores the effect of peoples' association with guide dogs on how they understand and feel about themselves and how they are regarded by those with whom they interact. The concepts of personal, collective, and social identity are used to situate the discussion. Of central importance is the way working with a guide dog shapes public interaction and how owner' self definitions and social identities are extended by being intimately involved in the owner—dog team.
