Relative age effect on elite tennis strategy

Relative age influences participation in professional tennis. The purpose of the current investigation was to compare the %net points played between players born in the first 6 months of the calendar year (H1 players) and players born in the second 6 months (H2 players). There were 116 players included in the current investigation because net statistics were provided for at least 6 of their matches in the 2011 to 2013 US Opens and the 2012 to 2014 Australian Opens. Players were also classified by generation; born before 1 January 1985 or after due to the introduction of surface grading in 2002. The %net points for male players was significantly influenced by generation (p = 0.041) and the interaction of generation and half year of birth (p = 0.040). The 17 H1 male players born in 1985 or later played 12.1+2.5% net points compared with 10.4+2.8% for the 16 H2 male players born in 1985 or later. The H1 players may have developed a greater tendency to go to the net as junior players with a relative age advantage. These players have continued to play more net points as seniors even though they no longer have a relative age advantage.
CHALLENGES TO BUILDING INFORMATION MODELLING IMPLEMENTATION IN UK: DESIGNERS' PERSPECTIVES

Building information modelling (BIM) has been proposed as a technology enabled process for the realisation of the performance ambitions of the construction industry through integrated management of information in virtual 3-D formats. Significant challenges however exist which undermine its implementation within the construction industry. The identification of these challenges is an imperative precondition for successful implementation of BIM given the associated risk. The design phase has particularly been cited as a significant beneficiary of process improvement and efficiency gains expected from the deployment of BIM. Despite the critical role of the design phase to project delivery and consequently BIM usage, few studies have sought to interrogate the challenges faced by designers. A qualitative approach was adopted through semi-structured interviews to solicit perspectives of UK design firms on the implementation challenges being faced. Findings reveal a categorisation of challenges as design-specific, team-orientated, project-related, technology related (BIM specific), industry-wide challenges and cost. This categorisation is used as a basis for identifying critical challenges which include: design process lag and loss of time; lack of understanding by clients regarding requirements for the BIM model; lack of learning feedback from projects on which BIM has been used; and lack of supply chain integration. Variation in the challenges across different maturity levels of firms is also confirmed in this study, particularly in relation to cost of implementation. Awareness of these challenges provides opportunities for identifying effective solutions for their mitigation.
Updated and Expanded OPAL Equation-of-State Tables: Implications for Helioseismology

We are in the process of updating and extending the OPAL equation-of-state (EOS) and opacity data to include low-mass stars. The EOS part of that effort now is complete, and the results are described herein. The new data cover main-sequence stars having mass ≥0.1 M☉. As a result of the more extreme matter conditions encountered with low-mass stars, we have added new physics. The electrons are now treated as relativistic, and we have improved our treatment of molecules. We also consider the implications of the new results for helioseismology.
Congruence and Performance of Value Concepts in Social Research

Two value concepts are dominant in the social sciences: (1) Schwartz's theory of basic human values, measured through the Portrait Values Questionnaire (ESS) and (2) Inglehart's postmaterialism and Welzel's extension to the self-expression values scale (WVS/EVS). To advance research in values, two questions need to be addressed: (1) Are the concepts and measurements of values in the different approaches interchangeable? (2) Which of the concepts performs better for explaining moral and social attitudes? This study contributes to the discussion on value concepts by comparing these value instruments using individual level data from an online access panel (n = 762) and assessing the performance of values instruments for microexplanations of moral (end-of-life attitudes and sexual morality) and social attitudes (xenophobia). Overall, the measurement model of basic human values with the PVQ provides a sound basis for comparing the Schwartz values to postmaterialism and self-expression values. In both cases, there are positive correlations with universalism and self-direction and negative correlations with tradition/conformity and security, which do not exceed 0.4. Regarding the performance, it turns out that the Schwartz values are in toto a more powerful tool than both Inglehart's postmaterialism and Welzel's self-expression values, in terms of explained variance as well as in terms of standardized effects.
Continuous measurements at the urban roadside in an Asian megacity by Aerosol Chemical Speciation Monitor (ACSM): Particulate matter characteristics during fall and winter seasons in Hong Kong

Abstract. Non-refractory submicron aerosol is characterized using an Aerosol Chemical Speciation Monitor (ACSM) in the fall and winter seasons of 2013 on the roadside in an Asian megacity environment in Hong Kong. Organic aerosol (OA), characterized by application of Positive Matrix Factorization (PMF), and sulfate are found to be dominant. Traffic-related organic aerosol shows good correlation with other vehicle-related species, and cooking aerosol displays clear mealtime concentration maxima and association with surface winds from restaurant areas. Contributions of individual species and OA factors to high NR-PM1 are analyzed for hourly data and daily data; while cooking emissions in OA contribute to high hourly concentrations, particularly during mealtimes, secondary organic aerosol components are responsible for episodic events and high day-to-day PM concentrations. Clean periods are either associated with precipitation, which reduces secondary OA with a lesser impact on primary organics, or clean oceanic air masses with reduced long-range transport and better dilution of local pollution. Haze events are connected with increases in contribution of secondary organic aerosol, from 30 to 50 % among total non-refractory organics, and the influence of continental air masses.
The role of stress history on the flow of fluids through fractures

Abstract Understanding flow along fractures and faults is of importance to the performance assessment (PA) of a geological disposal facility (GDF) for radioactive waste. Flow can occur along pre-existing fractures in the host-rock or along fractures created during the construction of the GDF within the excavation damage zone (EDZ). The complex fracture network will have a range of orientations and will exist within a complex stress regime. Critical stress theory suggests that fractures close to localized shear failure are critically stressed and therefore most conductive to fluid flow. Analysis of fault geometry and stress conditions at Sellafield has revealed that no features were found to be, or even close to being, classified as critically stressed, despite some being conductive. In order to understand the underlying reasons why non-critically stressed fractures were conductive a series of laboratory experiments were performed. A bespoke angled shear rig (ASR) was built in order to study the relationship between fluid flow (water and gas) through a fracture surface as a function of normal load. Fluid flow reduced with an increase in normal load, as expected. During unloading considerable hysteresis was seen in flow and shear stress. Fracture flow was only partially recovered for water injection, whereas gas flow increased remarkably during unloading. The ratio of shear stress to normal stress seems to control the fluid flow properties during the unloading stage of the experiment demonstrating its significance in fracture flow. The exhumation of the Sellafield area during the Palaeogene-Neogene resulted in considerable stress relaxation and in fractures becoming non-critically stressed. The hysteresis in shear stress during uplift has resulted in faults remaining, or becoming, conductive. The field and laboratory observations illustrate that understanding the stress-history of a fractured rock mass is essential, and a mere understanding of the current stress regime is insufficient to estimate the flow characteristics of present-day fractures.
The Link Between Leader-Member Exchange, Organizational Citizenship Behavior and Job Satisfaction: A Case Study on Local Government

Being the lowest level of government after Federal and State governments, local governments are considered as the managers of urban environment due to their multifarious services functions which drives the economic growth and social development of a particular district. The heterogeneous services provided are constantly being reviewed and appraised by the public where statistics from Public Complaint Bureau showed worrying numbers with high number of complaints being recorded for four consecutive years ending 2012. Hence, the goal of this study is to analyse the impact of leader-member exchange (LMX) and organizational citizenship behaviour (OCB) on job satisfaction using 212 respondents from local governments’ employees in east coast Malaysia. The findings showed that LMX and OCB were predictors towards job satisfaction with LMX being the strongest predictor compared to OCB. Mean differences on job satisfaction, LMX and OCB according to selected demographic variables revealed significant mean differences were noted in service group for LMX and dyadic tenure for OCB. Based on these findings, nurturing quality relationship and promoting the occurrence of OCB among local government employees are warranted as empirical evidence proved that they are important ingredients in provoking employees’ job satisfaction.
Optimistic versus Pessimistic--Optimal Judgemental Bias with Reference Point

This paper develops a model of reference-dependent assessment of subjective beliefs in which loss-averse people optimally choose the expectation as the reference point to balance the current felicity from the optimistic anticipation and the future disappointment from the realization.The choice of over-optimism or over-pessimism depends on the real chance of success and optimistic decision makers prefer receiving early information. In the portfolio choice problem, pessimistic investors tend to trade conservatively, however, they might trade aggressively if they are sophisticated enough to recognise the biases since low expectation can reduce their fear of loss.
Avalanches de débris sur le flanc occidental du volcan-bouclier Piton des Neiges (Réunion)

–The Saint-Gilles breccias, on the western flank of Piton des Neiges volcano, are clearly identified as debris avalanche deposits. A petrographic, textural and structural analysis of the breccias and inter-bedded autochthonous lava flows enables us to distinguish at least four successive flank slides. The oldest deposit sampled the hydrothermally-altered inner parts of the volcano, and has a large volume. Failure was favored by the presence of a deep intensely-weathered layer. The younger deposits are from superficial sources, as their products are rarely hydrothermalized and are more vesicular. The breccia formation, and especially the progressive breaking up occurring during the debris avalanche displacement, indicates the existence of high speed transport. In the Cap La Houssaye coastal area, abrasion and striation of the underlying lava formation, as well as the packing features observed in the breccia, are considered to be deceleration structures.
The role and value of nurses in care provision: Views and expectations of Emirati Nationals in the western region of Abu Dhabi, United Arab Emirates

Background: Reliable health user information is needed to effectively organize nursing services and deliver quality patientcentered care. Nurse leaders of Al Gharbia Health Services (AGHS) noted that although budget data and general workforce information were readily available, detailed information about patient experiences, views, and expectations was lacking. Objective: This study aimed to obtain preliminary data regarding health and nursing service expectations of Emirati nationals in the remote western region of Abu Dhabi, United Arab Emirates (UAE). Methods: This study used qualitative descriptive methodology. Semi-structured interviews were conducted with a sample of Emirati families who had recently accessed AGHS. Interviews focused on service user understanding and expectations of the role of nurses, nursing services, and the health service overall. Results: Emirati nationals’ views and expectations regarding nurses’ role and function in the healthcare team were highlighted. Participants’ expectations and the attributes they valued were distributed across two distinct areas: clinical competence and the “softer” skills of compassion, caring, and respect. Conclusions: These findings facilitate understanding of the expectations of Emirati health service users. Importantly, the results counter regional perceptions of nursing under-valued as a servant role across the UAE and broader Gulf Cooperation Council region. The findings may inform a range of activities including: a large-scale survey regarding the views and expectations of Emirati health service users; pre-service nursing education and nursing in service development; and the recruitment of Emirati nationals to the nursing profession. Further investigation regarding perceptions and valuing of nursing within the Emirati community is warranted.

In fact they improve protein expressions patterns, leading to an increase of potato yield by increasing number of tubers and tubers weight. Production history of tubers mothers anlight influence also significantly potato yield.
Investment in Employees and Research and Development and the Signalling of Intellectual Capital by UK Listed Companies

This paper examines the cross-sectional effect of investment in employees and investment in research and development on the extent of voluntary disclosure of intellectual capital of 443 FTSE All Share Index companies for the year 2003/2004. The extent of disclosure is measured by a disclosure index based on intellectual capital attributes included in the narratives and illustrations of the annual reports. The paper predicts that agency costs may be minimised through voluntary disclosure. In addition, that in some industries, the benefits of signalling valuable, rare, inimitable and non-substitutable attributes may outweigh the competitive costs of reporting this information. The results suggest that large companies operating in non-manufacturing, high-tech and innovative industries that are characterised by investment in employees and research and development processes have higher levels of hidden value; these companies are associated with the signalling of intellectual capital.
Employment Adjustment in Portugal: Evidence from Aggregate and Firm Data

This paper examines the pattern of employment adjustment in Portugal. First, the issue is addressed using a long time series of aggregate data. Although the employment data show persistence, there is nonetheless a fairly rapid rate of employment adjustment. Second, a much shorter time series of firm data is used to check the persistence detected at aggregate level, and also to examine the contribution of atypical work over the cycle. Consistent with the aggregate evidence, and despite stronger employment inertia, there is no suggestion in the firm panel that labour demand is cyclically unstable.
Metal Inert Gas (Mig) Welding Parameters Optimization

Metal Inert Gas welding (MIG) process is an important welding operation for joining ferrous and non ferrous metals. The MIG input welding parameters are the most important factors affecting the quality of the welding and weld quality is strongly characterized by weld bead geometry. This paper presents the effect of welding parameters like welding current, welding voltage, welding speed on penetration depth of AISI 1020 steel during welding. A plan of experiments based on Taguchi technique has been used to plan the experiment, acquire the data and to optimize the welding parameters as well as the process. Finally the conformations tests have been carried out to get the difference between the predicated values with the experimental values to find the effectiveness in the analysis of penetration.
An Empirical Analysis of The Stochastic Implications of Stock Price Movements in The Nigerian Capital Market

The study provides further empirical insight on the behavior of stocks in four selected sectors of the Nigerian economy using the Runs and GARCH techniques to analyze monthly stock data for the period January to December, 2011. The results of the Runs Test do not support random movements of stocks in all the sectors, indicating homoscedasticity. The GARCH estimated model also shows volatility clustering in all the sectors except the Agricultural sector, which implies weak form inefficiency of the Nigerian capital market. Keywords: Randomness; stochastic movements; runs; GARCH; homoscedasticity; heteroscedasticity; Nigeria
Generalised model of primary production in the southern Benguela upwelling system

We provide a proof-of-concept demonstration using a novel method for estimating depth-integrated distributions of chlorophyll from archives of data from ships, buoys or gliders combined with remotely sensed data of sea surface temperature (SST) and surface chlorophyll a (chl a) from satellites. Our area of application has contrasting hydrographic regimes, which include the dynamic southern Benguela upwelling system and the stratified waters of the Agulhas Bank, South Africa. The method involves using self-organising maps (SOMs), a type of artificial neural network, to identify 'typical' chl a profiles regardless of their statistical form, provided several of a similar shape have been found in the training set. These are arranged in a linear array, ranging from uniform profiles low in chl a to profiles with high surface or subsurface peaks. We then use generalised modelling to relate these characteristic profiles to remotely sensed surface features, viz. surface chl a and SST, as well as area, season, and water depth (a proxy for distance offshore). The model accounts for 87% of the variability in chl a profile and is used to predict the type of profile likely for each pixel in monthly remote sensing composites of SST and surface chl a and then to estimate integrated chl a and primary production with the aid of a light model. Primary production peaks in mid-summer, reaching 5 mgC m(-2) d(-1) locally, with an average over the whole area and all seasons of 1.4 mg C m(-2) d(-1). Seasonal variation is greatest in the southern part of the west coast, and lowest in the stratified southeast. Annual primary production for the southern Benguela region including the Agulhas Bank is ca. 156 million tC yr(-1). This is the most robust estimate of primary production in the Benguela system to date because it combines the spatial and temporal coverage provided by remote sensing with realistic vertical chl a profiles.

Waves in Honeycomb Structures

We review recent work of the authors on the non-relativistic Schr\"odinger equation with a honeycomb lattice potential, $V$. In particular, we summarize results on (i) the existence of Dirac points, conical singularities in dispersion surfaces of $H_V=-\Delta+V$ and (ii) the two-dimensional Dirac equations, as a large, but finite time, effective description of $e^{-iH_Vt}\psi_0$, for data $\psi_0$, which is spectrally localized at a Dirac point. We conclude with a formal derivation and discussion of the effective large time evolution for the nonlinear Schr\"odinger - Gross Pitaevskii equation for small amplitude initial conditions, $\psi_0$. The effective dynamics are governed by a nonlinear Dirac system.
Mortality pattern in Emergency Department of a Tertiary Care Center in Western Nepal

Background : There is abundance of evidence regarding various aspects of mortality in emergency department from different parts of world but there is limited number of studies on mortality in context of western Nepal. The objectives of this analysis were to review the demographical pattern of mortalities and define the cause and frequency of death in the Emergency Department (ED) of our institute within 24 hours of treatment process.Material and Methods : A retrospective study was carried out evaluating all patients who died during the treatment process in the Emergency Department of Lumbini Medical College in a three and half year of period from January 2014 to June 2017.Results : A total of 33,472 patients attended to ED with mortality rate of 36.4%, 33.6% and 28.2% on consecutive three years in which 110 deaths occurred. There were 66 (60%) male and 44 (40%) female. The highest mortality was seen after age of 60 years (range 2 month to 90 year). Non-communicable causes & stroke deaths were found to be higher in number. Most of our patient n=52 (47.3%) death occurred within 6-12 hours of admission in ED.Conclusion : Mortality within 24 hours of presentation at ED remains high. Well organized emergency setup, transport, development of protocol as well as new guideline will definitely help in reducing hospital mortalities.Journal of Nobel Medical CollegeVolume 6, Number 2, Issue 11 (July-December, 2017) Page:48-52
