An evaluation of the implications of the best interests of the child principle in the context of same-sex parenting in Ireland

Same-sex parenting is by no means a new phenomenon but the legal recognition and acceptance of gay and lesbian couples as parents is a relatively recent development in most countries. Traditionally, such recognition has been opposed on the basis of the claim that the best interests of children could not be met by gay and lesbian parents. This thesis examines the validity of this argument and it explores the true implications of the best interests principle in this context. The objective is to move away from subjective or moral conceptions of the best interests principle to an understanding which is informed by relevant sociological and psychological data and which is guided by reference to the rights contained in the UN Convention on the Rights of the Child. Using this perspective, the thesis addresses the overarching issue of whether the law should offer legal recognition and protection to gay and lesbian families and the more discrete matter of how legal protection should be provided. It is argued that the best interests principle can be used to demand that same-sex parenting arrangements should be afforded legal recognition and protection. Suggestions are also presented as to the most appropriate manner of providing for this recognition. In this regard, guidance is drawn from the English and South African experience in this area. Overall, the objective is to assess the current laws from the perspective of the best interests principle so as to ensure that the law operates in a manner which adheres to the rights and interests of children.

Broad-scale patterns of sex ratios in Patella spp.: a comparison of range edge and central range populations in the British Isles and Portugal

Sex change, or sequential hermaphroditism, occurs in the plant and animal kingdoms and often determines a predominance of the first sex. Our aim was to explore changes in sex ratios within the range of the species studied: Patella vulgata and Patella depressa. The broad-scale survey of sex with size of limpets covered a range of latitudes from Zambujeira do Mar (southern Portugal) to the English Channel. Indirect evidence was found for the occurrence of protandry in P. vulgata populations from the south of England, with females predominating in larger size-classes; cumulative frequency distributions of males and females were different; sex ratios were biased towards males and smallest sizes of males were smaller than the smallest sizes of females. In contrast in Portugal females were found in most size-classes of P. vulgata. In P. depressa populations from the south coast of England and Portugal females were interspersed across most size-classes; size distributions of males and females and size at first maturity of males and females did not differ. P. depressa did, however, show some indications of the possibility of slight protandry occurring in Portugal. The test of sex ratio variation with latitude indicated that P. vulgata sex ratios might be involved in determining the species range limit, particularly at the equatorward limit since the likelihood of being male decreased from the south coast of England to southern Portugal. Thus at the southern range limit, sperm could be in short supply due to scarcity of males contributing to an Allee effect.

Hate crime legislation and violence against sex workers in Ireland: Lessons in Policy and Practice

Drawing on data from UglyMugs.ie (a reporting mechanism for sex workers) this paper considers whether crimes against sex workers should be considered as hate crimes. In many ways, the debates around hate crime in the UK are more developed than in Ireland. As yet the Irish State has yet to criminalise the ‘hate’ element of crime and has been severely criticised for its relatively lacklustre approach to recording incidents of bias or hate crimes against certain social groups. The paper adopts the structural understanding of hate crime espoused by Barbara Perry (2001) who frames the dynamics of hate crime within a complex interplay of political, social and cultural factors. In our analysis we consider what is termed ‘whorephobia’ through the ambit of criminalisation and stigmatisation, gender and heteronormativity in Irish society, and the gendered nature of policing in both parts of Ireland.

Climate change and the evolution of loggerhead sex-ratio in Cabo Verde

[EN] Global warming can affect nesting success of sea turtles due to the rise of the sea level and the subsequent increased inundation or erosion of nesting beaches. Moreover, it can reduce male production to levels that can alter reproduction due to their temperature dependant sex determination (TSD). Now, mean nest temperatures all around the world predict a predominance of female hatchlings, and this trend may increase with global warming in the next decades.

Eph kinases and their ligands ephrins act in concert with sex hormones in regulating blood pressure

Les Erythropoietin-producing hepatocyte (EPH) sont la plus grande famille de récepteurs tyrosine kinase. Leurs ligands, les éphrines (EFNs), sont aussi des molécules exprimées à la surface cellulaire. Les EPH/EFNs sont impliqués dans de nombreux processus biologiques. L'hypertension artérielle (PA) est une maladie chronique qui, aujourd'hui, est devenue un problème médical critique dans le monde entier et un enjeu de santé publique. La découverte de nouvelles thérapeutiques de l'hypertension sont d'une grande importance pour la santé publique. Jusqu’à tout récemment, il existe seulement quelques études concernant le rôle de l’axe EPH/EFNs sur la fonction des cellules musculaires lisses vasculaires (CMLV). Dans nos études précédentes, nous avons montré qu'EPHB6 et EFNB1, de concert avec les hormones sexuelles, régulent la PA. Dans la présente étude, nous avons constaté que les différents membres de la famille EPH/EFN peuvent réguler soit positivement, soit négativement, la contractilité des CMLV et la PA: tandis que EPHB4 et EFNB2 appartiennent à la première catégorie, EFNB1, EFNB3 et EPHB6 appartiennent à la deuxième. In vivo, des souris males, mais non pas des femelles, porteuses d’une mutation EPHB4 (KO) spécifique du muscle lisse présentent une PA diminuée, comparée aux souris témoins (WT). Les CMLV de souris EPHB4 KO, en présence de testostérone, ont montré une contractilité réduite lors de la stimulation par la phényléphrine (PE). Au niveau moléculaire, la phosphorylation de la protéine kinase II dépendante de Ca2+/calmoduline et de la kinase de la chaine légère de la myosine (CLM) est augmentée, tandis que la phosphorylation de la kinase de la CLM est réduite dans les CMLV KO lors de la stimulation par PE, par rapport au WT CMLV. Cela fournit une base moléculaire à la réduction de la PA et de la contractilité des CMLV chez les souris EPHB4 KO. EFNB2 est le ligand majeur de l’EPHB4. Comme attendu, les souris EFNB2 KO spécifique du muscle lisse avaient un phénotype de PA semblable, quoique non identique, aux souris EPHB4 KO. Les souris mâles EFNB2 KO, mais pas femelles, sous régime régulier ou riche en sel, présentent une PA réduite, par rapport à leurs homologues WT. Au niveau cellulaire, les CMLV des souris KO ont montré une contractilité réduite lors de la stimulation par PE par rapport aux témoins WT. Une région de l’acide aminé (aa) 313 à l’aa 331 dans la partie intracellulaire d’EFNB2 est essentielle pour la signalisation inverse qui régule la contractilité des CMLV, selon des études de mutation-délétion. Dans une étude de génétique humaine, nous avons identifié, dans le gène EFNB2, six SNP qui étaient associées significativement au risque d'hypertension artérielle, de façon dépendante du sexe, ce qui corrobore nos résultats chez les souris. En revanche, la délétion du gène EFNB3 (KO) chez les souris femelles aboutit à une PA élevée et à une augmentation des résistances des petites artères in vivo, améliore la contractilité des petites artères ex-vivo et augmente la contractilité des CMLV in vitro. Les souris mâles KO ont une PA normale, mais la castration conduit à une augmentation significative de la PA dans les souris KO, mais pas dans les souris WT. Les CMLV des souris KO femelles ont montré une phosphorylation accrue de la CLM et une phosphorylation réduite de la kinase de la CLM, ce qui fournit à nouveau une base moléculaire aux phénotypes de PA et de contractilité des CMLV observés. Ce changement de signalisation est attribuable à une protéine adaptatrice Grip1. En effet, dans une étude d'association pan génomique par le Consortium International pour la Pression Sanguine, un SNP dans le gène GRIP1 a approché le seuil de significativité de la valeur p pour son association avec la pression diastolique. Nos recherches, pour la première fois, ont révélé que EPH/EFNs sont de nouveaux composants dans le système de régulation de la PA. Les membres de la famille EPH/EFN peuvent agir comme des forces Yin et Yang pour régler finement le tonus des vaisseaux pour assurer l'homéostasie de la PA et de sa régulation. Ces effets de EPH/EFNs dépendent du sexe et des niveaux d’hormones sexuelles. À partir de ces nouvelles connaissances, nous pourrions développer une nouvelle thérapie personnalisée pour l’hypertension artérielle, utilisant des antagonistes d'hormones sexuelles ou des thérapies de remplacement d'hormones sexuelles, selon les niveaux d'hormones sexuelles des patients et les mutations dans les gènes de l'EPH/EFN.

Black-White Wage Gap Among Restaurant Servers: A Replication, Extension, and Exploration of Consumer Racial Discrimination in Tipping

There is a rich history of social science research centering on racial inequalities that continue to be observed across various markets (e.g., labor, housing, and credit markets) and social milieus. Existing research on racial discrimination in consumer markets, however, is relatively scarce and that which has been done has disproportionately focused on consumers as the victims of race-based mistreatment. As such, we know relatively little about how consumers contribute to inequalities in their roles as perpetrators of racial discrimination. In response, in this paper we elaborate on a line of research that is only in its’ infancy stages of development and yet is ripe with opportunities to advance the literature on consumer racial discrimination and racial earnings inequities among tip dependent employees in the United States. Specifically, we analyze data derived from a large exit survey of restaurant consumers (n=378) in an attempt to replicate, extend, and further explore the recently documented effect of service providers’ race on restaurant consumers’ tipping decisions. Our results indicate that both White and Black restaurant customers discriminate against Black servers by tipping them less than their White coworkers. Importantly, we find no evidence that this Black tip penalty is the result of interracial differences in service skills possessed by Black and White servers. We conclude by delineating directions for future research in this neglected but salient area study.

Social Capital in Jordan: Wasta in Employment Selection

Social capital has emerged as a concept of great interest and potential to help understand and explain how social structures and networks impact political, social and business practices at the collective and individual levels. The basic premise is: investment in social relations will yield expected returns. Extant research has largely focused on the West; our knowledge of how social capital plays out in the Middle East is limited. We marry social capital with ‘wasta’, the strong family and tribal based connections secured in networks in the Arab world, and investigate HR managers’ perceptions of wasta in employment selection in Jordan. Often use of wasta in employment selection is related to favouritism and nepotism and the many negative outcomes of not adhering to merit-based selection. Through in-depth interview data we reveal a more nuanced and multifaceted view of wasta in employment selection. When examined through the social capital lens six distinct themes emerge: (i) wasta as an enabler to get jobs, (ii) wasta as social ties/ solidarity, (iii) wasta as a method to transfer/ attain information, (iv) wasta as a guide in decision-making, (v) wasta as an exchange, and (vi) wasta as pressure. Our findings confirm that at times wasta grants individuals unfair access to employment that is beyond their qualifications, skills, knowledge and/ or abilities. However, organisational context is relevant. In banking, not all roles are open to wasta. Where the possible negative impact on the organisation poses too great a risk HR managers feel able to resist even strong wasta. Context also emerges as being of key importance with regards to the background and business model of an organisation. Family businesses tend to operate wasta more frequently and extensively using tribal connections, religious networks and geographical area based networks as a key source in hiring. Despite globalisation and international nature of banking, wasta and tribalism feature strongly in daily business conduct in Jordan. Our paper illuminates the positive effects of wasta, e.g.as a method to transfer information, together with discussion on the dangers of ‘cloning’, a (lack of diversity), and the dangers of an incompetent workforce .

Sex ända in i skolbänken : En kvalitativ intervjustudie ur religionslärares perspektiv

Det här är en kvalitativ intervjustudie som syftar till att undersöka hur religionskunskapslärare undervisar om sexualitet i skiljelinjen mellan att upprätthålla antidiskrimineringslagen och värdegrunden, i samband med att skapa förståelse för religioners synsätt på sexualitet. Med kvalitativ forskningsintervju som metod, intervjuades fem religionskunskapslärare som undervisar på både gymnasiet och för grundskolans senare år. Därefter analyserades lärarnas utsagor utifrån toleranspedagogik, normkritisk pedagogik och existentiell relationspedagogik som teoretiska ramverk i syfte att tolka vilka didaktiska aspekter, möjligheter och svårigheter som är förknippat med deras undervisning om sexualitet. Resultatet visade att det fanns många likheter i hur de bedrev sin undervisning. Samtliga lärare upplevde att det finns en spänning mellan att värna om antidiskriminering och att skapa förståelse för religioners synsätt på sexualitet. Mangrant värnade de om rätten till att styra över sitt eget liv men också att det fanns nyansskillnader i vad man tryckte på i värdegrunden. Lärarna beskrev att de hanterade värdegrundskonflikter genom att markera, dra gränser mellan religionens och samhällets normer och diskutera. Vidare beskrev lärarna både didaktiska möjligheter och svårigheter med att undervisa om sexualitet inom religionsämnet och att de upplevde detta på olika sätt. För en stor del av de intervjuade fanns en gemensam nämnare i att det förekom didaktiska svårigheter förknippat med elevers negativa inställningar till homosexualitet men också om det fanns elever som tidigare varit utsatt för något.
