Socio-emotional effects of the transition from sight to blindness,

The research examined the socio-emotional impact of sight loss on a sample of 18 blind and partially sighted adults from the East coast of Scotland (average age 64). The impact of sight loss in four core areas mood, self concept, social connectedness and loss was explored. Data was collected using the mental health and social functioning sub-scales of the National Eye Institute Visual Functioning Questionnaire-25 and semi-structured interviews. Data indicated that participants experienced reduced mental health and decreased social functioning as a result of sight loss. Data also showed that participants shared common socio-emotional issues during transition from sight to blindness, starting with diagnosis, coping with deterioration of sight, experiencing loss, experiencing changed perceptions of self in relation to society, experiencing others in a changed way and experiencing rehabilitation. A theoretical model describing the socio-emotional transition from sight to blindness is proposed. Implications for practice are explored.

Identification of the Dynamic Parameters of a Real Bridge under Different Damage Conditions in a Field Experiment

This paper presents the results of a real bridge field experiment in which damage was applied artificially to a steel truss bridge. The aim of this paper is to identify the dynamic parameters of this bridge using conventional techniques and investigate the effect of various damage conditions on those parameters. In the field experiment, acceleration measurements were recorded at a number of locations on the bridge deck. To excite the bridge, a two-axle van was driven across the bridge at constant speed. Dynamic parameters, such as the bridge mode shape, natural frequency and damping constant, are identified from the acceleration signals using existing techniques such as the fast Fourier transform, logarithmic decrement and frequency domain decomposition. The variation of these parameters under the influence of artificially applied damage conditions is investigated in order to evaluate their sensitivity to the bridge damage.

Perceptions of collaboration between general practitioners and community pharmacists: Findings from a qualitative study based in Spain

According to the theory of reasoned action (TRA), collaboration is only possible when it is perceived as useful by the participants involved. This paper describes a qualitative study using semi-structured interviews to explore the preceived usefulness of general practitioner (GPs)-community pharmacists (CPs)' collaboration from these professionals' perspectives based in two Spanish regions. Thirty-seven interviews were conducted with GPs and CPs with and without previous experience of collaborating with the other groups of professionals. Analysis of the data indicated that the GPs and CPs considered that collaboration between practitioners and pharmacists to have different forms of usefulness, ranging from positive to negative perceptions of usefulness. Negative and neutral opinions (collaboration generates conflict and/or is not benefitial) could prevent practitioners from initiating collaboration with the other group of professionals, which is explained by the TRA. These perceptions were only found among those participants without experience in collaboration. When collaboration was perceived as advantageous, it could be beneficial on three levels: health system (i.e. provision of integrated care, increased efficiency of the system), GPs and CPs (i.e. increased job satisfaction and patient loyalty) and patients (i.e. improved patient safety). Although GPs and CPs with experience identified benefits using a range of examples, GPs and CPs who had never collaborated also believed that if collaboration was undertaken there would be benefits for the health system, patients and health professionals. These results should be considered when developing strategies to encourage and improve the implementation of collaborative working relationships between GPs and pharmacists in primary care.

Adolescents’ relationship with God and internalizing adjustment over time: The moderating role of maternal religious coping

A growing literature supports the importance of understanding the link between religiosity and youths' adjustment and development, but in the absence of rigorous, longitudinal designs, questions remain about the direction of effect and the role of family factors. This paper investigates the bidirectional association between adolescents' relationship with God and their internalizing adjustment. Results from 2-wave, SEM cross-lag analyses of data from 667 mother/adolescent dyads in Belfast, Northern Ireland (50% male, M age = 15.75 years old) supports a risk model suggesting that greater internalizing problems predict a weaker relationship with God 1 year later. Significant moderation analyses suggest that a stronger relationship with God predicted fewer depression and anxiety symptoms for youth whose mothers used more religious coping.

A New Stereocontrolled Total Synthesis of the Mast Cell inhibitory Alkaloid, (+)-Monanchorin, via the Wittig Reaction of a Stabilized Ylide with a Cyclic Guanidine Hemiaminal

Abstract Image

An asymmetric total synthesis of the mast cell inhibitor (+)-monanchorin is reported in which a Sharpless AD on 11 and a cyclic sulfate ring opening with an azide feature as key steps. After further manipulation, a novel guanidine-controlled ester reduction provided the guanidine-hemiaminal 25 which underwent Wittig olefination to give 27. Hydrogenation and a second guanidine-controlled reduction of the ester in 28, to obtain aldehyde 29, then set up a trifluoroacetic acid mediated cyclization to give (+)-monanchorin TFA salt.

Community pharmacists and people with dementia: a cross-sectional survey exploring experiences, attitudes, and knowledge of pain and its management

Objectives
To explore community pharmacists' experiences with and attitudes towards people with dementia, and to determine the knowledge they have about pain and its management in this patient population. 

Methods
A questionnaire comprising five sections, including the Approaches to Dementia Questionnaire, was mailed, on two occasions, during February and March 2011, to all community pharmacies in Northern Ireland (n=530). 

Results
The response rate was 34.3%. A greater proportion of pharmacists provided pharmaceutical care to people with dementia living at home (91.2%) than those living in care homes (40.1%). Respondents most frequently encountered queries relating to starting and stopping medications, compliance with medication, and availability of formulation types. The mean total score for the Approaches to Dementia Questionnaire measure was 72.8, indicating a positive attitude towards people with dementia, and respondents demonstrated a strong person-centred approach towards this patient population. The majority of respondents recognised the difficulty of assessing pain in people with dementia; however, younger pharmacists (p=0.041) and pharmacists who provided pharmaceutical care to people with dementia (p=0.012) were more likely to be aware of the pain assessment tools for use in people with dementia. Pharmacists appeared uncertain about how to appropriately manage pain in people with dementia.

Conclusions
The study has revealed that community pharmacists often encounter people with dementia, especially those living in their own homes, and they have positive attitudes towards the patient population. However, training in the assessment and management of pain in people with dementia must be developed to further improve their knowledge in this area. 

Organising EU non-discrimination law around the nodes of ‘race’ gender and disability?

EU non-discrimination law has seen a proliferation of discrimination grounds from 2000. Dis-crimination on grounds of gender (in the field of equal pay) and on grounds of nationality (generally within the scope of application of EU law) were the only prohibited forms of discrimination in EU law, until the Treaty of Amsterdam empowered the Community to legislate in order to combat discrimination on grounds of sex, racial or ethnic origin, religion or belief, disability, age or sexual orientation (Article 13 EC). Proliferation of non-discrimination grounds is also characteristic for international and national non-discrimination law. As such, proliferation of grounds results in an increase in potential cases of “multiple discrimination” and the danger of diluting the demands of equality law by ever more multiplication of grounds. The hierarchy of equality, which has been so widely criticised in EU law, is a signifier of the latter danger.
This chapter proposes to structure the confusing field of non-discrimination grounds by organising them around nodes of discrimination fields. It will first reflect different ways of establishing hierarchies between grounds. This will be followed by a recount of different (narrow and wide) reading of grounds. A comprehensive reading of the grounds gender, ‘race’ and disability as establishing overlapping fields of discrimination grounds will be mapped out, with some examples for practical uses.

The British conservative party and Europe:The choosing of John Major

This article provides an empirical analysis of voting behaviour in the second ballot of the 1990 Conservative leadership contest that resulted in John Major becoming party leader and prime minister. Seven hypotheses of voting behaviour are generated from the extant literature relating voting to socio-economic variables (occupational and educational background), political variables (parliamentary experience, career status, age and electoral marginality) and ideological variables (drawn from survey data on MPs' positions on economic, European and moral issues). These hypotheses are tested using data on voting intentions gathered from published lists of MPs' declarations, interviews with each of the leadership campaign teams, and correspondence with MPs. Bivariate relationships are presented, followed by logistic regression analysis to isolate the unique impact that each variable had on voting. This shows that educational background, parliamentary experience and (especially) attitudes to Europe were the key factors determining voting. The importance of Europe in the contest is particularly instructive: the severe problems for Major's leadership which were caused by the issue can be attributed to, and understood in the context of, the 1990 contest in which he became leader.

The structure of an unconventional HD-GYP protein from Bdellovibrio reveals the roles of conserved residues in this class of cyclic-di-GMP phosphodiesterases

UNLABELLED: Cyclic-di-GMP is a near-ubiquitous bacterial second messenger that is important in localized signal transmission during the control of various processes, including virulence and switching between planktonic and biofilm-based lifestyles. Cyclic-di-GMP is synthesized by GGDEF diguanylate cyclases and hydrolyzed by EAL or HD-GYP phosphodiesterases, with each functional domain often appended to distinct sensory modules. HD-GYP domain proteins have resisted structural analysis, but here we present the first structural representative of this family (1.28 Å), obtained using the unusual Bd1817 HD-GYP protein from the predatory bacterium Bdellovibrio bacteriovorus. Bd1817 lacks the active-site tyrosine present in most HD-GYP family members yet remains an excellent model of their features, sharing 48% sequence similarity with the archetype RpfG. The protein structure is highly modular and thus provides a basis for delineating domain boundaries in other stimulus-dependent homologues. Conserved residues in the HD-GYP family cluster around a binuclear metal center, which is observed complexed to a molecule of phosphate, providing information on the mode of hydroxide ion attack on substrate. The fold and active site of the HD-GYP domain are different from those of EAL proteins, and restricted access to the active-site cleft is indicative of a different mode of activity regulation. The region encompassing the GYP motif has a novel conformation and is surface exposed and available for complexation with binding partners, including GGDEF proteins.

IMPORTANCE: It is becoming apparent that many bacteria use the signaling molecule cyclic-di-GMP to regulate a variety of processes, most notably, transitions between motility and sessility. Importantly, this regulation is central to several traits implicated in chronic disease (adhesion, biofilm formation, and virulence gene expression). The mechanisms of cyclic-di-GMP synthesis via GGDEF enzymes and hydrolysis via EAL enzymes have been suggested by the analysis of several crystal structures, but no information has been available to date for the unrelated HD-GYP class of hydrolases. Here we present the multidomain structure of an unusual member of the HD-GYP family from the predatory bacterium Bdellovibrio bacteriovorus and detail the features that distinguish it from the wider structural family of general HD fold hydrolases. The structure reveals how a binuclear iron center is formed from several conserved residues and provides a basis for understanding HD-GYP family sequence requirements for c-di-GMP hydrolysis.

Modeling of titanium alloys by using artificial neural networks

Titanium alloy exhibits an excellent combination of bio-compatibility, corrosion resistance, strength and toughness. The microstructure of an alloy influences the properties. The microstructures depend mainly on alloying elements, method of production, mechanical, and thermal treatments. The relationships between these variables and final properties of the alloy are complex, non-linear in nature, which is the biggest hurdle in developing proper correlations between them by conventional methods. So, we developed artificial neural networks (ANN) models for solving these complex phenomena in titanium alloys.

In the present work, ANN models were used for the analysis and prediction of the correlation between the process parameters, the alloying elements, microstructural features, beta transus temperature and mechanical properties in titanium alloys. Sensitivity analysis of trained neural network models were studied which resulted a better understanding of relationships between inputs and outputs. The model predictions and the analysis are well in agreement with the experimental results. The simulation results show that the average output-prediction error by models are less than 5% of the prediction range in more than 95% of the cases, which is quite acceptable for all metallurgical purposes.

Quality of reporting of dental survival analyses

To explore the quality of reporting (writing and graphics) of articles that used time-to-event analyses to report dental treatment outcomes. A systematic search of the top 50 dental journals in 2008 produced the sample of articles for this analysis. Articles reporting treatment outcomes with (n = 95) and without (n = 91) time-to-event statistics were reviewed. Survival descriptive words used in the two groups were analysed (Pearson's chi-square). The quality of life tables, survival curves and time-to-event statistics were assessed (Kappa analysed agreement) and explored. Words describing dental outcomes 'over time' were more common in time-to-event compared with control articles (77%, 3%, P < 0.001). Non-specific use of 'rate' was common across both groups. Life tables and survival curves were used by 39% and 48% of the time-to-event articles, with at least one used by 82%. Construction quality was poor: 21% of life tables and 28% of survival curves achieved an acceptable standard. Time-to-event statistical reporting was poor: 3% achieved a high and 59% achieved an acceptable standard. The survival statistic, summary figure and standard error were reported in 76%, 95% and 20% of time-to-event articles. Individual statistical terms and graphic aids were common within and unique to time-to-event articles. Unfortunately, important details were regularly omitted from statistical descriptions and survival figures making the overall quality poor. It is likely this will mean such articles will be incorrectly indexed in databases, missed by searchers and unable to be understood completely if identified.

An experimental evaluation of prediction models for the mechanical behavior of unreinforced, lime-mortar masonry under compression

This paper contributes to the understanding of lime-mortar masonry strength and deformation (which determine durability and allowable stresses/stiffness in design codes) by measuring the mechanical properties of brick bound with lime and lime-cement mortars. Based on the regression analysis of experimental results, models to estimate lime-mortar masonry compressive strength are proposed (less accurate for hydrated lime (CL90s) masonry due to the disparity between mortar and brick strengths). Also, three relationships between masonry elastic modulus and its compressive strength are proposed for cement-lime; hydraulic lime (NHL3.5 and 5); and hydrated/feebly hydraulic lime masonries respectively.

Disagreement between the experimental results and former mathematical prediction models (proposed primarily for cement masonry) is caused by a lack of provision for the significant deformation of lime masonry and the relative changes in strength and stiffness between mortar and brick over time (at 6 months and 1 year, the NHL 3.5 and 5 mortars are often stronger than the brick). Eurocode 6 provided the best predictions for the compressive strength of lime and cement-lime masonry based on the strength of their components. All models vastly overestimated the strength of CL90s masonry at 28 days however, Eurocode 6 became an accurate predictor after 6 months, when the mortar had acquired most of its final strength and stiffness.

The experimental results agreed with former stress-strain curves. It was evidenced that mortar strongly impacts masonry deformation, and that the masonry stress/strain relationship becomes increasingly non-linear as mortar strength lowers. It was also noted that, the influence of masonry stiffness on its compressive strength becomes smaller as the mortar hydraulicity increases.

EU Social and Labour Rights and EU Internal Market Law: Study for the EMPL Committee

EU Social and Labour Rights have developed incrementally, originally through a set of legislative initiatives creating selective employment rights, followed by a non-binding Charter of Social Rights. Only in 2009, social and labour rights became legally binding through the Charter of Fundamental Rights for the European Union (CFREU). By contrast, the EU Internal Market - an area without frontiers where goods, persons, services and capital can circulate freely – has been enshrined in legally enforceable Treaty provisions from 1958. These comprise the economic freedoms guaranteeing said free circulation and a system ensuring that competition is not distorted within the Internal Market (Protocol 27 to the Treaty of Lisbon). Tensions between Internal Market law and social and labour rights have been observed in analyses of EU case law and legislation. This study explores responses by socio-economic and political actors at national and EU levels to such tensions, focusing on collective labour rights, rights to fair working conditions and rights to social security and social assistance (Articles 12, 28, 31, 34 Charter of Fundamental Rights for the European Union). On the basis of the current Treaties and the CFREU, the constitutionally conditioned Internal Market emerges as a way to overcome the perception that social and labour rights limit Internal Market law, or vice versa. On this basis, alternative responses to perceived tensions are proposed, focused on posting of workers, furthering fair employment conditions through public procurement and enabling effective collective bargaining and industrial action in the Internal Market.
