Different influences on lexical priming for integrative, thematic, and taxonomic relations.
Word pairs may be integrative (i.e., combination of two concepts into one meaningful entity; e.g., fruit-cake), thematically related (i.e., connected in time and place; e.g., party-cake), and/or taxonomically related (i.e., shared features and category co-members; e.g., muffin-cake). Using participant ratings and computational measures, we demonstrated distinct patterns across measures of similarity and co-occurrence, and familiarity for each relational construct in two different item sets. In a standard lexical decision task (LDT) with various delays between prime and target presentation (SOAs), target RTs and priming magnitudes were consistent across the three relations for both item sets. However, across the SOAs, there were distinct patterns among the three relations on some of the underlying measures influencing target word recognition (LSA, Google, and BEAGLE). These distinct patterns suggest different mechanisms of lexical priming and further demonstrate that integrative relations are distinct from thematic and taxonomic relations
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
Protecting children from secondhand smoke: a mixed-methods feasibility study of a novel smoke-free home intervention
Background: Globally, 40 % of children under 14 years are regularly exposed to secondhand smoke (SHS), typically in their homes. There is limited evidence of the effectiveness of interventions to reduce children’s SHS exposure,and so the aim of this study was to test the feasibility and acceptability of a novel intervention to help parents and carers (caregivers) to reduce their children’s exposure to SHS at home.
Methods: A novel multi-component intervention to support caregivers to reduce their children’s SHS exposure athome was tested in a two-phase feasibility study. The 12-week intensive intervention delivered in the homeconsisted of three components: behavioural support, nicotine replacement therapy (NRT) for temporary abstinenceand feedback on levels of SHS exposure in the form of children’s salivary cotinine (phase 1) or home air quality (PM2.5) (phase 2). Participants were caregivers who smoked inside their homes and had at least one child under the age of 5 years living with them the majority of the time. Mixed-methods were used to explore the acceptability and feasibility of the intervention as well as processes, particularly around recruitment and retention, for an exploratory efficacy trial.
Results: Twelve caregivers completed the study, all received personalised feedback on SHS exposure and behavioural support to help them to make their homes smoke-free and the majority at least tried NRT. Saliva cotinine results were variable in phase 1, and therefore, measures of PM2.5 were used for feedback in phase 2.Behavioural support was well received with personalised feedback reported as being the key motivator for initiating and maintaining behaviour change.
Conclusions: Recruiting disadvantaged caregivers was labour intensive, but once recruited, this novel intervention was both feasible and acceptable in supporting caregivers to reduce their children’s exposure to SHS at home. It is appropriate to test the efficacy of this novel intervention in an exploratory randomised controlled trial
Endogenous transforming growth factor β1 suppresses inflammation and promotes survival in adult CNS
Transforming growth factor β1 (TGFβ1) is a pleiotropic cytokine with potent neurotrophic and immunosuppressive properties that is upregulated after injury, but also expressed in the normal nervous system. In the current study, we examined the regulation of TGFβ1 and the effects of TGFβ1 deletion on cellular response in the uninjured adult brain and in the injured and regenerating facial motor nucleus. To avoid lethal autoimmune inflammation within 3 weeks after birth in TGFβ1-deficient mice, this study was performed on a T- and B-cell-deficient RAG2-/- background. Compared with wild-type siblings, homozygous deletion of TGFβ1 resulted in an extensive inflammatory response in otherwise uninjured brain parenchyma. Astrocytes increased in GFAP and CD44 immunoreactivity; microglia showed proliferative activity, expression of phagocytosis-associated markers [αXβ2, B7.2, and MHC1 (major histocompatibility complex type 1)], and reduced branching. Ultrastructural analysis revealed focal blockade of axonal transport, perinodal damming of axonal organelles, focal demyelination, and myelin debris in granule-rich, phagocytic microglia. After facial axotomy, absence of TGFβ1 led to a fourfold increase in neuronal cell death (52 vs 13%), decreased central axonal sprouting, and significant delay in functional recovery. It also interfered with the microglial response, resulting in a diminished expression of early activation markers [ICAM1 (intercellular adhesion molecule 1), α6β1, and αMβ2] and reduced proliferation. In line with axonal and glial findings in the otherwise uninjured CNS, absence of endogenous TGFβ1 also caused an ∼10% reduction in the number of normal motoneurons, pointing to an ongoing and potent trophic role of this anti-inflammatory cytokine in the normal as well as in the injured brain.

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
Chemical Composition, Fiber Morphology, and Pulping of P. Bolleana Lauche
The chemical composition and fiber morphology of the P. bolleana Lauche was assessed for its suitability for pulping and papermaking. The P. bolleana Lauche used in this study contained a low amount of lignin, but higher quantities of cellulose and hemicelluloses. It was found that morphological indices of P. bolleana Lauche were adequate for pulping and papermaking. The pulping of this wood was carried out using conventional kraft and soda pulping process under varying conditions. The results indicated that at higher sulfidity (24%-32%) with lower EA (14-16%), higher yields, and viscosity of pulping were obtained with an acceptable kappa number. Kraft pulp of P. bolleana Lauche obtained at given conditions (EA 14-16%; sulfidity 24-32%) provided paper sheets with greater tensile strength, burst index and tear index, at the same beating degree
Localized effects of offshore aquaculture on water quality in a tropical sea
Aquaculture production has increased steadily in many tropical countries over the past few decades, although impact assessments have been frequently neglected. We investigated the impacts of an offshore barramundi fish farm on water quality in the southern-central Red Sea, a traditionally understudied tropical, oligotrophic, and semi-enclosed basin. Inorganic nutrients, particulate matter, chlorophyll-a, and heterotrophic bacteria were measured periodically over 8 months around the farm. Water down-current from the farm had, on average, more heterotrophic bacteria and chlorophyll-a than up-current (11% and 34% higher, respectively). Ratios of dissolved inorganic nitrogen:phosphorus down-current from the farm were lower than ratios up-current (mean 9.8 vs 16.0, respectively). Phosphate, inorganic nitrogen, and particulate matter showed patterns of enrichment associated with the farm after a fish feeding event. Strategies such as feed optimization and considering hydrodynamics in site selection may improve water quality for future fish farms in Saudi Arabia and other tropical countries.En prens

Patients' experiences of deep brain stimulation for Parkinson's disease: a qualitative systematic review and synthesis.
Published onlineJournal ArticleThis is the final version of the article. Available from BMJ Publishing Group via the DOI in this record.OBJECTIVE: To review and synthesise qualitative research studies that have explored patients' experience of deep brain stimulation (DBS) in advanced Parkinson's disease (PD). DESIGN: Systematic review and meta-synthesis of 7 original papers, using metaethnography. SETTING: Studies conducted in Denmark, France and Sweden. PARTICIPANTS: 116 patients who had undergone DBS and 9 spouses of patients. RESULTS: Prior to surgery, the experience of advancing PD is one of considerable loss and a feeling of loss of control. There are significant hopes for what DBS can bring. Following surgery, a sense of euphoria is described by many, although this does not persist and there is a need for significant transitions following this. We suggest that normality as a concept is core to the experience of DBS and that a sense of control may be a key condition for normality. Experience of DBS for patients and spouses, and of the transitions that they must undertake, is influenced by their hopes of what surgery will enable them to achieve, or regain (ie, a new normality). CONCLUSIONS: There is a need for further qualitative research to understand the nature of these transitions to inform how best patients and their spouses can be supported by healthcare professionals before, during and after DBS. In assessing the outcomes of DBS and other treatments in advanced PD, we should consider how to capture holistic concepts such as normality and control. Studies that examine the outcomes of DBS require longer term follow-up.This work was part funded by the Medical Research Council Midland Hub for Trials Methodology Research (Grant Number: G0800808).

Healthcare resource utilization and related financial costs associated with glucose lowering with either exenatide or basal insulin: a retrospective cohort study
Aims
Type 2 diabetes is a major health problem placing increasing demands on healthcare systems. Our objective was to estimate healthcare resource use and related financial costs following treatment with exenatide‐based regimens prescribed as once‐weekly (EQW) or twice‐daily (EBID) formulations, compared with regimens based on basal insulin (BI).
Materials and methods
This retrospective cohort study used data from the UK Clinical Practice Research Datalink (CPRD) linked to Hospital Episode Statistics (HES). Patients with type 2 diabetes who received exenatide or BI between 2009 and 2014 as their first recorded exposure to injectable therapy were selected. Costs were attributed to primary care contacts, diabetes‐related prescriptions and inpatient admissions using standard UK healthcare costing methods (2014 prices). Frequency and costs were compared between cohorts before and after matching by propensity score using Poisson regression.
Results
Groups of 8723, 218 and 2180 patients receiving BI, EQW and EBID, respectively, were identified; 188 and 1486 patients receiving EQW and EBID, respectively, were matched 1:1 to patients receiving BI by propensity score. Among unmatched cohorts, total crude mean costs per patient‐year were £2765 for EQW, £2549 for EBID and £4080 for BI. Compared with BI, the adjusted annual cost ratio (aACR) was 0.92 (95% CI, 0.91‐0.92) for EQW and 0.82 (95% CI, 0.82‐0.82) for EBID. Corresponding costs for the propensity‐matched subgroups were £2646 vs £3283 (aACR, 0.80, 0.80‐0.81) for EQW vs BI and £2532 vs £3070 (aACR, 0.84, 0.84‐0.84) for EBID vs BI.
Conclusion
Overall, exenatide once‐weekly and twice‐daily‐based regimens were associated with reduced healthcare resource use and costs compared with basal‐insulin‐based regimens
