Abstract The origin and life history of 186 Atlantic salmon caught at sea within Icelandic waters were investigated using microsatellites to assess the origin and scales and otoliths to assess freshwater and sea age. A total of 184 samples were aged using scales or otolithes or both. Most of the samples were from individuals in their first year at sea (72.8%). The freshwater age varied from 1 to 5 years with an average of 2.6 years. The most common freshwater age was 2 years (42%), with a further substantial proportion of 3-year-old fish (28%). Genetic assignment of individual fish to their most likely population of origin was performed using Bayesian genetic individual assignments with a baseline consisting of 284 Eastern Atlantic rivers and 466 sample sites genotyped at the 14 microsatellite. A total of 186 samples of salmon caught at sea were assigned to their origin. Eight samples, from post-smolts and caught close to land, were assigned as having come from Iceland. Of the remaining 178 samples, 121 individuals (68%) were from the Southern Group, i.e. from mainland Europe, the UK, and Ireland, 53 individuals (30%) were from the Northern Group, i.e. Scandinavia and Northern Russia, and 4 individuals were from Iceland (2%). Stock mixture proportions were estimated for four periods using ONCOR and cBAYES. Stock mixture analysis generally supported the individual assignments, but did not suggest a seasonal component to the distribution of salmon stocks. These results indicate that the sea south and east of Iceland are important as feeding areas for migrating Atlantic salmon, particularly for salmon originating in the UK, Ireland, and southern Europe. Furthermore, the lack of adult Icelandic fish so close to Iceland is remarkable and suggests that Atlantic salmon from Icelandic stocks are using different feeding grounds.

Gender transformations are normatively understood as somatic, based on surgical reassignment, where the sexed body is aligned with the gender identity of the individual through genital surgery – hence the common lexicon ‘sex change surgery’. We suggest that the UK Gender Recognition Act 2004 challenges what constitutes a ‘sex change’ through the Act's definitions and also the conditions within which legal ‘recognition’ is permitted. The sex/gender distinction, (where sex normatively refers to the sexed body, and gender, to social identity) is demobilised both literally and legally. This paper discusses the history of medico-socio-legal definitions of sex have been developed through decision making processes when courts have been faced with people with gender variance and, in particular, the implications of the Gender Recognition Act for our contemporary legal understanding of sex. We ask, and attempt to answer, has ‘sex’ changed?

Background: Associations of early antibiotics exposures with childhood asthma, allergies, and airway illnesses are debated. Objectives: We aimed to investigate associations of first-year antibiotics exposure with childhood asthma, allergies, and airway illnesses. Methods: A cross-sectional study was conducted among preschoolers in Shanghai, China during 2011–2012. A questionnaire regarding household environment and lifestyles and childhood health outcomes was reported by the child’s parents. Results: In total, 13,335 questionnaires (response rate: 85.3%) were analyzed and 3049 (24.1%) children had first-year antibiotics exposure. In the multivariate logistic regression analyses, first-year antibiotics exposure had significant associations with the higher odds of lifetime-ever pneumonia (adjusted OR, 95% CI: 2.15, 1.95–2.37), croup (1.46, 1.24–1.73), wheeze (1.44, 1.30–1.60), asthma (1.38, 1.19–1.61), food allergy (1.29, 1.13–1.46), and allergic rhinitis (1.23, 1.07–1.41), and as well as current (one year before the survey) common cold (≥3 times) (1.38, 1.25–1.52), dry cough (1.27, 1.13–1.42), atopic dermatitis (1.25, 1.09–1.43), wheeze (1.23, 1.10–1.38), and rhinitis symptoms (1.15, 1.04–1.26). These associations were different in children with different individual characteristics (age, sex, family history of atopy, and district) and other early exposures (breastfeeding, home decoration, pet-keeping, and environmental tobacco smoke). Conclusions: Our results indicate that first-year antibiotics exposure could be a strong risk factor for childhood pneumonia, asthma, allergies, and their related symptoms. The individual characteristics and other early exposures may modify effects of early antibiotic exposure on childhood allergies and airway illnesses.

The word ‘compassion’ is ubiquitous in modern healthcare. Yet few writers agree on what the term means, and what makes it an essential trait in nursing. In this article, I take a historical approach to the problem of understanding compassion. Although many modern writers have assumed that compassion is a universal and unchanging trait, my research reveals that the term is extremely new to healthcare, only becoming widely used in 2009. Of course, even if compassion is a new term in nursing, the concept could have previously existed under another name. I thus consider the emotional qualities associated with the ideal nurse during the interwar period in the UK. While compassion was not mentioned in nursing guidance in this era another term, ‘sympathy’, made frequent appearance. The interwar concept of sympathy, however, differs significantly from the modern one of compassion. Sympathy was not an isolated concept. In the interwar era, it was most often linked to the nurse’s tact or diplomacy. A closer investigation of this link highlights the emphasis laid on patient management in nursing in this period, and the way class differentials in emotion between nurse and patient were considered essential to the efficient running of hospitals. This model of sympathy is very different from the way the modern ‘compassion’ is associated with patient satisfaction or choice. Although contemporary healthcare policy assumes ‘compassion’ to be a timeless, personal characteristic rooted in the individual behaviours and choices of the nurse, this article concludes that compassionate nursing is a recent construct. Moreover, the performance of compassion relies on conditions and resources that often lie outside of the nurse’s personal control. Compassion in nursing—in theory and in practice—is inseparable from its specific contemporary contexts, just as sympathy was in the interwar period.

This essay examines the Vegetarian Advocate, a British monthly periodical that ran from 1848 to 1850, and it argues that the periodical’s serial form shaped its representation of vegetarianism. As the first official organ of the UK Vegetarian Society, the Vegetarian Advocate carried different messages to different audiences. For members of the Society, it circulated information on the organization’s publications, annual meetings, membership statistics, and finances, subjects that would be of interest only to insiders. For outsiders and the uninitiated, it published articles explaining vegetarian principles, using arguments drawn from physiology, chemistry, natural history, economics, and ethics to persuade curious readers to experiment with a vegetarian diet. However, drawing on press scholarship and Michel Foucault’s techniques of the self, this essay argues that the serial form of the periodical itself carried an important message on the vegetarians’ ‘serialization of life’, their belief that life be lived serially or, in other words, that forward progress and self-improvement come through repetition, attention to routine, and the everyday training of oneself. Specifically, this essay claims that the seriality of the Vegetarian Advocate allowed the Vegetarian Society to represent its dietary regimen as serial — that is, as a repetitive yet progressive, sequential system of self-transformation in which all forms of activity (from eating to exercising to socializing) accrued meaning sequentially, serially, and relationally, orientating vegetarianism and vegetarians towards a teleological objective, or what Foucault calls the ‘telos of the ethical subject’. Serialization, it claims, was integral to both the practice and concept of vegetarianism: vegetarian print materials were published serially while the practice itself was conceptualized as a progressive step in the development of the individual and the species.

PurposeNon-suicidal self-injury (NSSI) is reasonably common, particularly among young people with prevalence rates of up to 25 per cent reported. Many factors contribute towards NSSI, including depression, anxiety and history of abuse and NSSI is a risk factor for suicide. Many people who engage in NSSI do not seek help, potentially due to concern about sigmatising attitudes. The purpose of this paper is to investigate the impact of gender and disclosure on stigmatising attitudes towards individuals who engage in NSSI.Design/methodology/approachParticipants were 384 first-year university students (77.4 per cent female; mean age 19.50 years (SD=3.53)) who completed measures of stigmatising attitudes in response to vignettes featuring individuals who engaged in self-harming behaviour. Vignettes varied in the gender of the individual as well as whether the NSSI was disclosed or not.FindingsThe results support the attribution model of public discrimination in relation to NSSI stigma. Perceptions of higher personal responsibility for NSSI behaviour and higher levels of danger and manipulation were positively associated with stigmatizing attitudes and behaviours. Male research participants reported significantly higher levels of stigmatizing attitudes and behaviours than females.Social implicationsThe level of stigmatising attitudes towards individuals who engage in NSSI is significant and may impact on help-seeking behaviour.Originality/valueBetween 10 and 25 per cent of adolescents engage in some form of NSSI, but only a minority seek help to address this behaviour. This study suggests that attitudes by peers may influence help-seeking. Further research is required outside of tertiary education settings.

SummaryPhilosophy both influences and is influenced by clinical and legal practice relating to suicide. This article begins with a brief history of attitudes in the UK and Europe towards those who attempt suicide. It describes the main philosophical positions regarding suicide, including the principle of respect for life, the utilitarian position, the theological principle, and the principles of autonomy and duty to others. It concludes that short-term interventions are justified in most cases, for example when the suicide attempt is a ‘cry for help’ and/or the individual is ambivalent in their attempt or likely to have a mental illness.

138 Atlantic salmon (Salmo salar) captured in the Advent Fjord off Svalbard were genetically assigned to two main clusters of European salmon. Two-thirds were assigned to salmon rivers in Finnmark (the northernmost county in Norway) and the rest to salmon rivers further south in Norway. The genetic assignment was based on genetic profiles from 60 Norwegian rivers. The two clusters correspond to two larger genetic groupings: the Barents–White seas and Atlantic groupings. Thus, we cannot rule out other populations from these groupings as sources of Atlantic salmon at Svalbard. Svalbard salmon assigned to the two genetic groupings differed in ecological and phenological traits, with highest smolt age and lowest postsmolt growth in the Finnmark salmon cluster. High smolt ages in both groups, however, suggest a northern origin of most individuals in the sample. Although Atlantic salmon have sporadically been observed in the Arctic Ocean at earlier times, the high abundance outlined here seems to be a recent phenomenon, suggesting a northward penetration caused by climate change.

In April 2017, the European Court of Human Rights ruled that requiring trans people to undergo sterilisation in order to grant legal gender recognition was a breach of human rights. In the UK, sterilisation has never been a legal requirement for trans people. However, hysterectomy and salpingo-oopherectomy have been strongly encouraged for trans masculine people on medical grounds, although the clinical evidence for current recommendations is weak. Within this article I analyse the issue from a feminist perspective and argue that current presumptions in favour of surgical intervention are influenced by the history of medical interventions to “fix” bodies perceived as female, coupled with a strong social taboo against the pregnant man. As a consequence, medical and legal frameworks are not necessarily facilitating optimal outcomes for the individual. I suggest that practices in this regard should be critically examined, with a view to developing more tailored, person-centred practices and facilitating informed choice.

This article focuses at powers of the Presidents of the Slovak Republic during the period from 1999 to 2019. Therefore, the aim is to compare how selected constitutional presidential powers were exercised after the fundamental constitutional changes in 1999. The most significant change was by introducing direct presidential elections, and adjusting the President´s constitutional status. The ways how the individual Presidents holding their office within this period, exercised their powers towards the Parliament, government, and the judiciary do form the basic research questions here. Hence, whether a personal background of individual Presidents and political reality of seats distribution in the Parliament predetermined their exercise of these powers, or if there were some other rules present when they exercised their office. The findings presented in this research reflect 20 years of continuous exercise of Presidential office in the conditions of the Slovak Republic. This ultimately leads to the conclusion that the function itself, as well as its constitutional definition, has affected the exercise of Presidential powers more ultimately than the personal background of these directly elected Presidents at the beginning of their terms of office. The very first President, Mr. Michal Kováč, got into a major conflict with then Prime Minister, Vladimír Mečiar, even during the first year after taking the office. This conflict lasted nearly for five-years and altogether with the inability of the MPs to elect his successor led to the necessity of amending the Constitution. Presidents Rudolf Schuster, Ivan Gašparovič and Andrej Kiska gradually took their office, but only the second mentioned had managed to defend his position in an electoral competition. At present, the office of President is held by Zuzana Čaputová, who has been in the office since June 2019 - as the very first woman in this position in history of Slovakia.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.
