Children, sexuality and sexualization

The entry below from ‘the sex goddess blues’ offers sage advice about the trials and tribulations of sociocultural and interpersonal shame and its effects on sexual expression, sexual exploration and sexual consent: Confidence in yourself is a lifelong process. It’s sometimes a long and winding road with potholes, roadblocks, and even massive collisions. The best place to start is to know that you, as a person, are worthwhile … You’re worth fighting for; you deserve good things in your life. You deserve to set goals for yourself. You deserve healthy relationships that make you feel good. You deserve to have your voice heard. You deserve to physically present yourself however you want. You deserve to feel at peace with your body. And, if you’re interested in sex, be it by yourself or with partners, you deserve pleasure and joy. ‘The Sex Goddess Blues: Building Sexual Confidence and Busting Perfectionism’, 2014, www.scarletteen.or

Whose personal is more political? Experience in contemporary feminist politics

Whose personal is more political? This paper rethinks the role of experience in contemporary feminism, arguing that it can operate as a form of capital within abstracted and decontextualised debates which entrench existing power relations. Although experiential epistemologies are crucial to progressive feminist thought and action, in a neoliberal context in which the personal and emotional is commodified powerful groups can mobilise traumatic narratives to gain political advantage. Through case study analysis this paper shows how privileged feminists, speaking for others and sometimes for themselves, use experience to generate emotion and justify particular agendas, silencing critics who are often from more marginalised social positions. The use of the experiential as capital both reflects and perpetuates the neoliberal invisibilisation of structural dynamics: it situates all experiences as equal, and in the process fortifies existing inequalities. This competitive discursive field is polarising, and creates selective empathies through which we tend to discredit others¹ realities instead of engaging with their politics. However, I am not arguing for a renunciation of the politics of experience: instead, I ask that we resist its commodification and respect varied narratives while situating them in a structural frame

New genetic loci implicated in fasting glucose homeostasis and their impact on type 2 diabetes risk.

Levels of circulating glucose are tightly regulated. To identify new loci influencing glycemic traits, we performed meta-analyses of 21 genome-wide association studies informative for fasting glucose, fasting insulin and indices of beta-cell function (HOMA-B) and insulin resistance (HOMA-IR) in up to 46,186 nondiabetic participants. Follow-up of 25 loci in up to 76,558 additional subjects identified 16 loci associated with fasting glucose and HOMA-B and two loci associated with fasting insulin and HOMA-IR. These include nine loci newly associated with fasting glucose (in or near ADCY5, MADD, ADRA2A, CRY2, FADS1, GLIS3, SLC2A2, PROX1 and C2CD4B) and one influencing fasting insulin and HOMA-IR (near IGF1). We also demonstrated association of ADCY5, PROX1, GCK, GCKR and DGKB-TMEM195 with type 2 diabetes. Within these loci, likely biological candidate genes influence signal transduction, cell proliferation, development, glucose-sensing and circadian regulation. Our results demonstrate that genetic studies of glycemic traits can identify type 2 diabetes risk loci, as well as loci containing gene variants that are associated with a modest elevation in glucose levels but are not associated with overt diabetes

Group differences in physician responses to handheld presentation of clinical evidence: a verbal protocol analysis

<p>Abstract</p> <p>Background</p> <p>To identify individual differences in physicians' needs for the presentation of evidence resources and preferences for mobile devices.</p> <p>Methods</p> <p>Within-groups analysis of responses to semi-structured interviews. Interviews consisted of using prototypes in response to task-based scenarios. The prototypes were implemented on two different form factors: a tablet style PC and a pocketPC. Participants were from three user groups: general internists, family physicians and medicine residents, and from two different settings: urban and semi-urban. Verbal protocol analysis, which consists of coding utterances, was conducted on the transcripts of the testing sessions. Statistical relationships were investigated between staff physicians' and residents' background variables, self-reported experiences with the interfaces, and verbal code frequencies.</p> <p>Results</p> <p>47 physicians were recruited from general internal medicine, family practice clinics and a residency training program. The mean age of participants was 42.6 years. Physician specialty had a greater effect on device and information-presentation preferences than gender, age, setting or previous technical experience. Family physicians preferred the screen size of the tablet computer and were less concerned about its portability. Residents liked the screen size of the tablet, but preferred the portability of the pocketPC. Internists liked the portability of the pocketPC, but saw less advantage to the large screen of the tablet computer (F[2,44] = 4.94, p = .012).</p> <p>Conclusion</p> <p>Different types of physicians have different needs and preferences for evidence-based resources and handheld devices. This study shows how user testing can be incorporated into the process of design to inform group-based customization.</p

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

A genome-wide association search for type 2 diabetes genes in African Americans.

African Americans are disproportionately affected by type 2 diabetes (T2DM) yet few studies have examined T2DM using genome-wide association approaches in this ethnicity. The aim of this study was to identify genes associated with T2DM in the African American population. We performed a Genome Wide Association Study (GWAS) using the Affymetrix 6.0 array in 965 African-American cases with T2DM and end-stage renal disease (T2DM-ESRD) and 1029 population-based controls. The most significant SNPs (n = 550 independent loci) were genotyped in a replication cohort and 122 SNPs (n = 98 independent loci) were further tested through genotyping three additional validation cohorts followed by meta-analysis in all five cohorts totaling 3,132 cases and 3,317 controls. Twelve SNPs had evidence of association in the GWAS (P<0.0071), were directionally consistent in the Replication cohort and were associated with T2DM in subjects without nephropathy (P<0.05). Meta-analysis in all cases and controls revealed a single SNP reaching genome-wide significance (P<2.5×10(-8)). SNP rs7560163 (P = 7.0×10(-9), OR (95% CI) = 0.75 (0.67-0.84)) is located intergenically between RND3 and RBM43. Four additional loci (rs7542900, rs4659485, rs2722769 and rs7107217) were associated with T2DM (P<0.05) and reached more nominal levels of significance (P<2.5×10(-5)) in the overall analysis and may represent novel loci that contribute to T2DM. We have identified novel T2DM-susceptibility variants in the African-American population. Notably, T2DM risk was associated with the major allele and implies an interesting genetic architecture in this population. These results suggest that multiple loci underlie T2DM susceptibility in the African-American population and that these loci are distinct from those identified in other ethnic populations

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

The problem with protection: Or, why we need to move towards recognition and the sexual agency of children

Drawing on historical and contemporary reform narratives, we highlight the implications of and problems with the discourse of protection and its conceptualization of childhood sexuality. Within the reform materials discussed, the child's sexuality is constructed as the result of a dangerous and socially unacceptable outside stimulus, and as a result, any realization of subjective sexual expression is rendered abhorrent and in need of adult intervention. It is our contention that sexual agency is unthinkable and ultimately unattainable within this model. Drawing on the recent work of Judith Butler we forward her theory of recognition as a framework for rethinking the sexuality of children. We argue that foregrounding recognition will help us create a cultural context that fosters sexual agency and in so doing promotes the sexual citizenship of children

Endangered Girls and Incendiary Objects: Unpacking the Discourse on Sexualization

In this article, we deconstruct the epistemological framework underlying recent discussions on the sexualization of girls. Conducting a close textual analysis of scholarly and activist writings and their media coverage in Australia, Britain and the United States we examine the foundational assumptions of the argument against sexualization and explore its potential social and political implications. It is our contention that the conceptualization of sexualization as both a process and outcome relies on an ambivalent and overly deterministic model which makes the danger of sexualizing materials uniform, but their outcome gender specific. The unintended consequence of this discourse is that girls are framed as passive recipients and their sexuality becomes the result of and reduced to sexualization
