Reflections on Communicating Science through Art

If science can inspire art, can art inspire interest and learning about science? There is widespread experimentation in using the arts as tools for communicating science in science museums and other settings. When the arts work well in communicating important aspects of science, they can be powerful tools. Three artworks are discussed: Particle Fever, a film in development about particle physicists and the hunt for the mysterious Higgs Boson; The Great Immensity, a National Science Foundation‐supported musical about climate change: and Guardians, a ballet co‐produced by and performed in an aquarium. These three art‐and‐science hybrids have given this writer some understanding of at least one way to sift the successful from the unsuccessful ventures.     

Eysenck's BIG THREE and communication traits: Communication traits as manifestations of temperament

Two studies are reported which sought to determine the possible limitations of the proposition that “temperament is manifest through communication.”; The results of earlier studies suggest that many communication related traits indeed are correlated with one or more temperament variables. In the present study Willingness to Communicate, Singing Apprehension, and Innovativeness were found to be associated with one or more of the BIG THREE temperament variables. Writing apprehension was found to have no meaningful relationship with any of the temperament variables. It is concluded that, while most important oral communication traits probably are correlated with one or more temperament traits, some other communication traits, like writing apprehension, may not be.     

Determination of the swing technique characteristics and performance outcome relationship in golf driving for low handicap female golfers

Abstract

Previous studies on the kinematics of the golf swing have mainly focused on group analysis of male golfers of a wide ability range. In the present study, we investigated gross body kinematics using a novel method of analysis for golf research for a group of low handicap female golfers to provide an understanding of their swing mechanics in relation to performance. Data were collected for the drive swings of 16 golfers using a 12-camera three-dimensional motion capture system and a stereoscopic launch monitor. Analysis of covariance identified three covariates (increased pelvis–thorax differential at the top of the backswing, increased pelvis translation during the backswing, and a decrease in absolute backswing time) as determinants of the variance in clubhead speed (adjusted r ² = 0.965, P < 0.05). A significant correlation was found between left-hand grip strength and clubhead speed (r = 0.54, P < 0.05) and between handicap and clubhead speed (r = ?0.612, P < 0.05). Flexibility measures showed some correlation with clubhead speed; both sitting flexibility tests gave positive correlations (clockwise: r = 0.522, P < 0.05; counterclockwise: r = 0.711, P < 0.01). The results suggest that there is no common driver swing technique for optimal performance in low handicap female golfers, and therefore consideration should be given to individual swing characteristics in future studies.     

Statistical methods for analysing discrete and categorical data recorded in performance analysis

In this paper, we identify appropriate statistical methods for analysing categorical differences in discrete variables or 'performance indicators' resulting from performance analysis. The random mechanisms associated with discrete events do not follow a normal distribution; that is, the normal distribution is a continuous not a discrete probability distribution. We propose appropriate statistical methods based on two key discrete probability distributions, the Poisson and binomial distributions. Two approaches are proposed and compared using examples from notational analysis. The first approach is based on the classic chi-square test of significance (both the goodness-of-fit test and the test of independence). The second approach adopts a more contemporary method based on log-linear and logit models fitted using the statistical software GLIM. Provided relatively simple one-way and two-way comparisons in categorical data are required, both of these approaches result in very similar conclusions. However, as soon as more complex models or higher-order comparisons are required, the approach based on log-linear and logit models is shown to be more effective. Indeed, when investigating those factors and categorical differences associated with binomial or binary response variables, such as the proportion of winners when attempting decisive shots in squash or the proportion of goals scored from all shots in association football, logit models become the only realistic method available. By applying log-linear and logit models to discrete events resulting from notational analysis, greater insight into the underlying mechanisms associated with sport performance can be achieved.     

Workload and non-contact injury incidence in elite football players competing in European leagues

Purpose: The aim of this study was to analyse the relationship between absolute and acute:chronic workload ratios and non-contact injury incidence in professional football players and to assess their predictive ability. Methods: Elite football players (n?=?130) from five teams competing in European domestic and confederation level competitions were followed during one full competitive season. Non-contact injuries were recorded and using session rate of perceived exertion (s-RPE) internal absolute workload and acute:chronic (A:C) workload ratios (4-weeks, 3-weeks, 2-weeks and week-to-week) were calculated using a rolling days method. Results: The relative risk (RR) of non-contact injury was increased (RR?=?1.59, CI95%: 1.18–2.15) when a cumulative 4-week absolute workload was greater than 10629 arbitrary units (AU) in comparison with a workload between 3745 and 10628?AU. When the 3-week absolute workload was more than 8319?AU versus between 2822 and 8318?AU injury risk was also increased (RR=?1.46, CI95% 1.08–1.98). Injury incidence was higher when the 4-week A:C ratio was <0.85 versus >0.85 (RR?=?1.31, CI95%: 1.02–1.70) and with a 3-week A:C ratio >1.30 versus <1.30 (RR?=?1.37, CI95%: 1.05–1.77). Importantly, none of the A:C workload combinations showed high sensitivity or specificity. Conclusions: In elite European footballers, using internal workload (sRPE) revealed that cumulative workloads over 3 and 4 weeks were associated with injury incidence. Additionally, A:C workloads, using combinations of 2, 3 and 4 weeks as the C workloads were also associated with increased injury risk. No A:C workload combination was appropriate to predict injury.     

图书馆资源共享的目标

<正> 引言图书资源共享意味着由若干个图书馆共同发挥作用的一种工作方式。它的目标是为了提供有益的网络效果:1)能够为用户提供更多的资料或服务;2)保证图书馆以较低的费用维持一定水平的服务,或者在不增加费用的情况下增加服务,或者用较少的费用来提供更多的服务。所有这些,如果单独由一个图书馆来做,那花销要大得多。为了实现这些目标,必须对各个参加馆的工作方式加以调整,但是不能影响他们原来的工作职责。这些目标的实现,同样也离不开读者对自身的阅读习惯做些调整。     

Enacting Cultural Identities in Conversation: Managing Collaboration in Two Nonprofit Organizations

As they conduct the practical work of collaborating during meetings, nonprofit stakeholders construct, negotiate, and manage identities. In this article we use membership categorization analysis to explore how meeting participants avow and ascribe cultural identities during collaborative meetings in two nonprofit organizations. Examination of identification practices, including employing labels for ethnic categories and implicating cultural identities through category-relevant predicates—which are part of the practical work of collaborating in nonprofit organizations—can serve as an aid to understanding how stakeholders negotiate interorganizational collaboration in social interaction.
