Discourses of marriage in same-sex marriage debates in the UK press 2011–2014

This paper interrogates media representations of same-sex marriage debates in the UK using a combination of corpus linguistics tools and close reading, and drawing on Queer Linguistics. Following related work by Baker (2004), Love and Baker (2015), and Bachmann (2011), we analyse a 1.3 million-word corpus of UK national newspaper texts compiled for the Discourses of Marriage Research Group. Our corpus stretches from September 2011 and the announcement of a government consultation on same-sex marriage, to April 2014 when the first same-sex marriages took place. Using a top-down approach we investigate the discourses drawn upon in same-sex marriage debates (as indexed by keywords and key semantic fields) and uncover the binary social categories used to normalise social structures and hold the same-sex marriage debate in place. We also consider which social actors are (not) given a voice and/or agency and discuss how (same-sex) marriage is constituted

Arboviral bottlenecks and challenges to maintaining diversity and fitness during mosquito transmission.

The term arbovirus denotes viruses that are transmitted by arthropods, such as ticks, mosquitoes, and other biting arthropods. The infection of these vectors produces a certain set of evolutionary pressures on the virus; involving migration from the midgut, where the blood meal containing the virus is processed, to the salivary glands, in order to transmit the virus to the next host. During this process the virus is subject to numerous bottlenecks, stochastic events that significantly reduce the number of viral particles that are able to infect the next stage. This article reviews the latest research on the bottlenecks that occur in arboviruses and the way in which these affect the evolution and fitness of these viruses. In particular we focus on the latest research on three important arboviruses, West Nile virus, Venezuelan equine encephalitis virus and Chikungunya viruses and compare the differing effects of the mosquito bottlenecks on these viruses as well as other evolutionary pressures that affect their evolution and transmission

Identity and naming practices in British marriage and civil partnerships

This article demonstrates the continued prevalence of traditional, heteronormative practices regarding marriage and naming practices in Britain, and also considers the complex choices made by same-sex couples who marry in relation to whether there are any benefits in changing their surname. The study draws on data from an online survey of 1,000 UK respondents, and reveals that it continues to be viewed as more ‘normal’ for a woman to take her husband’s surname in a heterosexual union than for her to make any other choice. Whilst other options (such as the woman retaining the surname given to her by her parents, for instance) are often considered in relation to heterosexual marriage, these continue to be seen as a deviation from the norm. We find that the role of tradition is critical to heterosexual women’s decisions over what to do with their surname, whether they follow the culturally expected route or consciously deviate from it. Same-sex couples are broadly perceived to have comparably more freedom than heterosexuals regarding their names, and here we analyse whether this is the case. Through qualitative critical analysis of the discursive responses of those completing our survey, and some quantitative discussion of the data, we demonstrate that heteronormative assumptions about a woman’s role in a heterosexual relationship have continued salience and that this leads to a conscious and often difficult negotiation of her own identity as both an individual and a wife

Implicit homophobic argument structure: equal-marriage discourse in The Moral Maze

This article analyses the linguistic and discursive elements which contribute to the production of implicit homophobia. Explicit homophobia has been well documented and strategies for countering discriminatory language have been developed (Baker, 2014; Leap, 2012). However, our interest here is in documenting implicit homophobia, where homophobic beliefs are only hinted at, are disassociated from the speaker, or are embedded within discursive and argument structures. We decided to analyse the debate in the media around the introduction of equal or same­-sex marriage legislation in the UK. We focused our analysis on a series of radio programmes on BBC Radio 4, The Moral Maze, (2011­12) where the issue of same­-sex marriage was debated with a team of panelists and invited guests from a range of different organisations. Different perspectives on same sex marriage were discussed, in a seemingly objective and dispassionate way, where the interactants distanced themselves from homophobic beliefs and yet, implicitly subscribed to implicit homophobia. We used an analysis drawing on argumentation structure (Fairclough and Fairclough, 2012) and through focusing on stance, recontextualisation, imaginaries, and metaphor, we developed an analysis which made the way that implicit homophobia works more visible. In this way, we hope to foreground implicit homophobia, and develop a linguistic and discursive `toolkit’ which will enable it to be challenged and countered

Opposition as victimhood in newspaper debates about same-sex marriage

In this paper, we take a queer linguistics approach to the analysis of data from British newspaper articles which discuss the introduction of same-sex marriage. Drawing on methods from CDA and corpus linguistics, we focus on the construction of agency in relation to the government extending marriage to same-sex couples, and those resisting this. We show that opponents to same-sex marriage are represented and represent themselves as victims whose moral values, traditions, and civil liberties are being threatened by the state. Specifically, we argue that victimhood is invoked in a way that both enables and permits discourses of implicit homophobia

Mechanical properties of β-HMX

Background: For a full understanding of the mechanical properties of a material, it is essential to understand the defect structures and associated properties and microhardness indentation is a technique that can aid this understanding. Results: The Vickers hardness on (010), {011} and {110} faces lay in the range of 304-363 MPa. The Knoop Hardnesses on the same faces lay in the range 314-482 MPa. From etching of three indented surfaces, the preferred slip planes have been identified as (001) and (101). For a dislocation glide, the most likely configuration for dislocation movement on the (001) planes is (001) [100] (|b| = 0.65 nm) and for the (101) plane as (101) 101~(|b| = 1.084 nm) although (101) [010] (|b| = 1.105 nm) is possible. Tensile testing showed that at a stress value of 2.3 MPa primary twinning occurred and grew with increasing stress. When the stress was relaxed, the twins decreased in size, but did not disappear. The twinning shear strain was calculated to be 0.353 for the (101) twin plane. Conclusions: HMX is considered to be brittle, compared to other secondary explosives. Comparing HMX with a range of organic solids, the values for hardness numbers are similar to those of other brittle systems. Under the conditions developed beneath a pyramidal indenter, dislocation slip plays a major part in accommodating the local deformation stresses. © 2015 Gallagher et al.; licensee Springer

West Nile Virus Experimental Evolution in vivo and the Trade-off Hypothesis

In nature, arthropod-borne viruses (arboviruses) perpetuate through alternating replication in vertebrate and invertebrate hosts. The trade-off hypothesis proposes that these viruses maintain adequate replicative fitness in two disparate hosts in exchange for superior fitness in one host. Releasing the virus from the constraints of a two-host cycle should thus facilitate adaptation to a single host. This theory has been addressed in a variety of systems, but remains poorly understood. We sought to determine the fitness implications of alternating host replication for West Nile virus (WNV) using an in vivo model system. Previously, WNV was serially or alternately passed 20 times in vivo in chicks or mosquitoes and resulting viruses were characterized genetically. In this study, these test viruses were competed in vivo in fitness assays against an unpassed marked reference virus. Fitness was assayed in chicks and in two important WNV vectors, Culex pipiens and Culex quinquefasciatus. Chick-specialized virus displayed clear fitness gains in chicks and in Cx. pipiens but not in Cx. quinquefasciatus. Cx. pipiens-specialized virus experienced reduced fitness in chicks and little change in either mosquito species. These data suggest that when fitness is measured in birds the trade-off hypothesis is supported; but in mosquitoes it is not. Overall, these results suggest that WNV evolution is driven by alternate cycles of genetic expansion in mosquitoes, where purifying selection is weak and genetic diversity generated, and restriction in birds, where purifying selection is strong

The role of mothers-in-law in antenatal care decision-making in Nepal: a qualitative study

Background Antenatal care (ANC) has been recognised as a way to improve health outcomes for pregnant women and their babies. However, only 29% of pregnant women receive the recommended four antenatal visits in Nepal but reasons for such low utilisation are poorly understood. As in many countries of South Asia, mothers-in-law play a crucial role in the decisions around accessing health care facilities and providers. This paper aims to explore the mother-in-law’s role in (a) her daughter-in-law’s ANC uptake; and (b) the decision-making process about using ANC services in Nepal. Methods In-depth interviews were conducted with 30 purposively selected antenatal or postnatal mothers (half users, half non-users of ANC), 10 husbands and 10 mothers-in-law in two different (urban and rural) communities. Results Our findings suggest that mothers-in-law sometime have a positive influence, for example when encouraging women to seek ANC, but more often it is negative. Like many rural women of their generation, all mothers-in-law in this study were illiterate and most had not used ANC themselves. The main factors leading mothers-in-law not to support/ encourage ANC check ups were expectations regarding pregnant women fulfilling their household duties, perceptions that ANC was not beneficial based largely on their own past experiences, the scarcity of resources under their control and power relations between mothers-in-law and daughters-in-law. Individual knowledge and social class of the mothers-in-law of users and non-users differed significantly, which is likely to have had an effect on their perceptions of the benefits of ANC. Conclusion Mothers-in-law have a strong influence on the uptake of ANC in Nepal. Understanding their role is important if we are to design and target effective community-based health promotion interventions. Health promotion and educational interventions to improve the use of ANC should target women, husbands and family members, particularly mothers-in-law where they control access to family resources

Enhancement of the magnetic anisotropy of nanometer-sized Co clusters: influence of the surface and of the inter-particle interactions

We study the magnetic properties of spherical Co clusters with diameters between 0.8 nm and 5.4 nm (25 to 7500$ atoms) prepared by sequential sputtering of Co and Al2O3. The particle size distribution has been determined from the equilibrium susceptibility and magnetization data and it is compared to previous structural characterizations. The distribution of activation energies was independently obtained from a scaling plot of the ac susceptibility. Combining these two distributions we have accurately determined the effective anisotropy constant Keff. We find that Keff is enhanced with respect to the bulk value and that it is dominated by a strong anisotropy induced at the surface of the clusters. Interactions between the magnetic moments of adjacent layers are shown to increase the effective activation energy barrier for the reversal of the magnetic moments. Finally, this reversal is shown to proceed classically down to the lowest temperature investigated (1.8 K).Comment: 13 figures submitted to Phys. Rev.

Hierarchical information clustering by means of topologically embedded graphs

We introduce a graph-theoretic approach to extract clusters and hierarchies in complex data-sets in an unsupervised and deterministic manner, without the use of any prior information. This is achieved by building topologically embedded networks containing the subset of most significant links and analyzing the network structure. For a planar embedding, this method provides both the intra-cluster hierarchy, which describes the way clusters are composed, and the inter-cluster hierarchy which describes how clusters gather together. We discuss performance, robustness and reliability of this method by first investigating several artificial data-sets, finding that it can outperform significantly other established approaches. Then we show that our method can successfully differentiate meaningful clusters and hierarchies in a variety of real data-sets. In particular, we find that the application to gene expression patterns of lymphoma samples uncovers biologically significant groups of genes which play key-roles in diagnosis, prognosis and treatment of some of the most relevant human lymphoid malignancies.Comment: 33 Pages, 18 Figures, 5 Table
