Look-up Tables to Link 1991 Population Statistics to the 1998 Local Government Areas

Between 1995 and 1998 the local authority structure and geography of the United Kingdom was substantially revised. The two-tier system of local government was abolished in Wales, Scotland, and in parts of non-metropolitan England, and replaced with a single-tier system. This involved the creation of a new set of local authority area boundaries which in many places cut across those of the old districts. In addition, many of the local authorities unaffected by the reorganisation nonetheless had experienced small - though demographically significant - boundary changes since the last census. By the time the final phase of the reorganisation came into effect on 1st April 1998 the local government map of the United Kingdom was very different from that of April 1991. There is a need therefore to provide demographic and other geographically based data for the new geography for years prior to 1998. This paper aims to fill a part of this requirement by focusing on two important issues. First, it describes a look-up table detailing exactly how the 1998 local government geography relates to 1991 Census areas, and second, it sets out methods for producing 1991 Census data and mid-1991 population estimates (including single year age detail) for the new geography. A selection of the results produced by the described methods is included in tables and population pyramids

Iron K Lines from Gamma Ray Bursts

We present models for reprocessing of an intense flux of X-rays and gamma rays expected in the vicinity of gamma ray burst sources. We consider the transfer and reprocessing of the energetic photons into observable features in the X-ray band, notably the K lines of iron. Our models are based on the assumption that the gas is sufficiently dense to allow the microphysical processes to be in a steady state, thus allowing efficient line emission with modest reprocessing mass and elemental abundances ranging from solar to moderately enriched. We show that the reprocessing is enhanced by down-Comptonization of photons whose energy would otherwise be too high to absorb on iron, and that pair production can have an effect on enhancing the line production. Both "distant" reprocessors such as supernova or wind remnants and "nearby" reprocessors such as outer stellar envelopes can reproduce the observed line fluxes with Fe abundances 30-100 times above solar, depending on the incidence angle. The high incidence angles required arise naturally only in nearby models, which for plausible values can reach Fe line to continuum ratios close to the reported values.Comment: 37 pages, 10 figures.

This is an Accepted Manuscript of an article published by Taylor & Francis in Journal of Sports Sciences, available online: http://www.tandfonline.com/doi/abs/10.1080/02640410600982279A sample of 222 university athletes (mean age 19.8 years, s = 2.0), ranging in standard from university second team to international competitor, completed a measure of perceived support 2 weeks before an important competition or match. On the day before the competition or match, the athletes completed measures of stressors, stress, received support, and self-confidence. Moderated hierarchical regression analyses revealed the following key findings: (i) main effects for both perceived (DeltaR2 = 0.11) and received support (DeltaR2 = 0.14) upon self-confidence; (ii) stress-buffering effects for both perceived (DeltaR2 = 0.02) and received (DeltaR2 = 0.07) support upon self-confidence; (iii) when both aspects of support were considered simultaneously, stress-buffering effects were primarily attributable to the influence of received support. These results demonstrate the beneficial impact of social support on self-confidence, both directly and by reducing the negative effect of stress on self-confidence. Our findings emphasize the need to recognize the distinction between perceived and received support, both in terms of theory and the design of social support interventions with athletes

The CSGU: a measure of controllability, stability, globality, and universality attributions.

addresses: School of Sport and Health Sciences, University of Exeter, Exeter, Devon, UK.types: Journal Article© 2008 Human Kinetics, IncThis article reports initial evidence of construct validity for a four-factor measure of attributions assessing the dimensions of controllability, stability, globality, and universality (the CSGU). In Study 1, using confirmatory factor analysis, factors were confirmed across least successful and most successful conditions. In Study 2, following less successful performances, correlations supported hypothesized relationships between subscales of the CSGU and subscales of the CDSII (McAuley, Duncan, & Russell, 1992). In Study 3, following less successful performances, moderated hierarchical regression analyses demonstrated that individuals have higher subsequent self-efficacy when they perceive causes of performance as controllable, and/or specific, and/or universal. An interaction for controllability and stability demonstrated that if causes are perceived as likely to recur, it is important to perceive that causes are controllable. Researchers are encouraged to use the CSGU to examine main and interactive effects of controllability and generalizability attributions upon outcomes such as self-efficacy, emotions, and performance

The main and interactive effects of immediate and reflective attributions upon subsequent self-efficacy

This is an Accepted Manuscript of an article published by Taylor & Francis in European Journal of Sport Science, available online: http://www.tandfonline.com/doi/full/10.1080/17461390802594227#.VNIkhp1FDcsIn this study, we examined the effects of immediate and reflective attributions upon subsequent self-efficacy. At Time 1 (Day 1), 117 participants (mean age 25.8 years, s=8. 5) completed a measure of attributions after performance (immediate attributions). At Time 2 (Day 4), the participants completed the same measure of attributions (reflective attributions). At Time 3 (Day 7, 8 or 9), they completed a measure of self-efficacy relating to an up-coming performance. Immediately after more successful performances, global attributions were associated with higher subsequent self-efficacy; upon reflection, stable, global, and/or personal attributions were associated with higher subsequent self-efficacy. Immediately after and upon reflection of less successful performances, controllable attributions were associated with higher subsequent self-efficacy; an interaction for controllability and stability demonstrated that when causes are perceived as likely to recur, greater controllability is associated with higher subsequent self-efficacy. Results suggest that following more successful performances, analysis of reflective assessments of attributions may help to further understanding of the relationships between attributions and outcomes such as self-efficacy. This study serves as a stimulus for future research to examine relationships between attributions assessed across time and outcomes such as self-efficacy, as well as to examine interactions among attribution dimensions

Social Support and Performance in a Golf-Putting Experiment

publication-status: Publishedtypes: Articleas accepted for publication© 2010 Human Kinetics, Inc.This study examined the impact of a social support manipulation on performance. Participants with high and low levels of perceived support were randomly assigned to an experimental support or control condition, before completing a golf-putting task. Participants with high levels of perceived support performed at a higher level than those with low levels of perceived support. Participants in the support condition performed at a higher level than those in the control condition. A significant interaction was primarily attributable to the low perceived support participants in the support condition performing better than the low perceived support participants in the control condition. Participants in the support condition also experienced less frequent and distracting task-irrelevant thoughts compared with those in the control condition. These results suggest that experimentally manipulated support may lead to improvements in the performance of novices completing a golf-putting task, and that such support may be particularly important for those low in perceived support

The PASS-Q: the perceived available support in sport questionnaire.

This article provides initial evidence for the construct validity of the Perceived Available Support in Sport Questionnaire (PASS-Q), which assesses emotional, esteem, informational, and tangible support. In Study 1, confirmatory factor analyses provided evidence for a four-dimension factor structure. Correlations supported hypothesized relationships between the PASS-Q dimensions and the Social Support Survey questions (Richman, Rosenfeld, & Hardy, 1993). In Study 2, the four-dimension factor structure was supported in an independent sample. Further, higher levels of perceived available emotional, esteem, informational, and tangible support were associated with higher levels of self-confidence and lower levels of burnout. Researchers are encouraged to use the PASS-Q to examine the effects of perceived available support in sport contexts

The Bacterial Photosynthetic Reaction Center as a Model for Membrane Proteins

Membrane proteins participate in many fundamental cellular processes. Until recently, an understanding of the function and properties of membrane proteins was hampered by an absence of structural information at the atomic level. A landmark achievement toward understanding the structure of membrane proteins was the crystallization (1) and structure determination (2-5) the photosynthetic reaction center (RC) from the purple bacteria Rhodopseudomonas viridis, followed by that of the RC from Rhodobacter sphaeroides (6-17). The RC is an integral membrane protein-pigment complex, which carries out the initial steps of photosynthesis (reviewed in 18). RCs from the purple bacteria Rps. viridis and Rb. sphaeroides are composed of three membrane-associated protein subunits (designated L, M, and H), and the following cofactors: four bacteriochlorophylls (Bchl or B), two bacteriopheophytins (Bphe or [phi]), two quinones, and a nonheme iron. The cofactors are organized into two symmetrical branches that are approximately related by a twofold rotation axis (2, 8). A central feature of the structural organization of the RC is the presence of 11 hydrophobic [alpha]-helixes, approximately 20-30 residues long, which are believed to represent the membrane-spanning portion of the RC (3, 9). Five membrane-spanning helixes are present in both the L and M subunits, while a single helix is in the H subunit. The folding of the L and M subunits is similar, consistent with significant sequence similarity between the two chains (19-25). The L and M subunits are approximately related by the same twofold rotation axis that relates the two cofactor branches. RCs are the first membrane proteins to be described at atomic resolution; consequently they provide an important model for discussing the folding of membrane proteins. The structure demonstrates that [alpha]-helical structures may be adopted by integral membrane proteins, and provides confirmation of the utility of hydropathy plots in identifying nonpolar membrane-spanning regions from sequence data. An important distinction between the folding environments of water-soluble proteins and membrane proteins is the large difference in water concentration surrounding the proteins. As a result, hydrophobic interactions (26) play very different roles in stabilizing the tertiary structures of these two classes of proteins; this has important structural consequences. There is a striking difference in surface polarity of membrane and water-soluble proteins. However, the characteristic atomic packing and surface area appear quite similar. A computational method is described for defining the position of the RC in the membrane (10). After localization of the RC structure in the membrane, surface residues in contact with the lipid bilayer were identified. As has been found for soluble globular proteins, surface residues are less well conserved in homologous membrane proteins than the buried, interior residues. Methods based on the variability of residues between homologous proteins are described (13); they are useful (a) in defining surface helical regions of membrane and water-soluble proteins and (b) in assigning the side of these helixes that are exposed to the solvent. A unifying view of protein structure suggests that water-soluble proteins may be considered as modified membrane proteins with covalently attached polar groups that solubilize the proteins in aqueous solution

An Intervention to Increase Social Support and Improve Performance

This is a postprint of an article published in Journal of Applied Sport Psychology, 2009, Vol. 21, Issue 2, pp. 186 - 200© 2009 copyright Taylor & Francis. Journal of Applied Sport Psychology is available online at: http://www.tandfonline.com/toc/uasp20/currentThis study investigated the effects of a one-to-one intervention designed to increase social support and improve performance using a single-subject multiple baseline design. Participants were 3 high-level male golfers, mean age 25.0 years (SD = 2.6). All participants reported significantly higher levels of emotional, esteem, informational, and tangible support in the intervention phase compared to the baseline phase (ts = -2.35 to -21.80, ps < .01). The performance of all participants improved during the intervention phase compared to the baseline phase. Participant A improved by an average of .90 shots per round, Participant B by 1.33 shots per round, and Participant C by 3.10 shots per round. The effectiveness of the intervention upon performance outcome was supported by a χ2 analysis (χ2 (1) = 4.80, p < .05). The results indicate that a one-to-one intervention may be a useful strategy to increase social support and improve performance

Enacted support and golf-putting performance: The role of support type and support visibility

Objectives This study examined whether the impact of enacted support on performance differed across type (esteem and informational) and visibility (visible and invisible) of support. It further tested whether self-efficacy mediated the enacted support-performance relationship. Design A one-factor (support manipulation) between subjects experiment. Method A fellow novice golfer — in reality a confederate — was scripted to randomly provide one of five support manipulations (visible informational support, invisible informational support, visible esteem support, invisible esteem support, and no support) to participants (n = 105). Immediately after, participants completed a self-efficacy measure and then performed a golf-putting task. Results The results demonstrated that participants given visible esteem support significantly outperformed those given no support and those given invisible esteem support. Participants given invisible informational support significantly outperformed those given no support. Although non-significant, the observed mean difference and moderate effect size provided weak evidence that those in the invisible informational support condition may have performed at a higher level than those in the visible informational support condition. There was no evidence that self-efficacy could explain any of these effects. Conclusion The results suggest that enacted support can benefit novices’ performance and that it is crucial to consider both the type and the visibility of the support. Esteem support is particularly effective when communicated in an explicit and direct manner but informational support appears more effective when communicated in a more subtle, indirect manner
