Cooperative Trends in Digital Archiving: An Open Discussion     

Marilyn Geller  Daviess Menefee  Eileen Fenton 《期刊图书馆员》2013,64(1-2):155-169

In putting together the NASIG strategy session “Cooperative Trends in Digital Archiving,” the three panelists, Daviess Menefee (Elsevier), Eileen Fenton (Portico), and Marilyn Geller (Lesley University), discussed issues they faced in their own organizations. All three panelists shared concerns about the need for archiving in general and for archiving born digital journals specifically, and about core organizational values that led them to pursue digital archiving. They had common concerns about who should be involved in digital archiving projects and how it should be accomplished. There were some interesting parallels in the decision making process within each organization. In this presentation, each of the panelists discussed how and why they came to their decisions, and how they all relied on the CLIR report, E-Journal Archiving Metes and Bounds, ¹ 1.

Meeting of the Minds: Online Matching Program for Teaching and Learning Styles?     

Celeste Fenton  Brenda Ward Watkins 《Community College Journal of Research & Practice》2013,37(12):1157-1167

Although there are many disagreements on the major causes of problems in the educational system in the United States, few would disagree that the importance of ensuring the success of our students is not only a moral obligation to our youth, but imperative to our national resilience. And, as a nation, we are responding to this urgent need. The College Completion Agenda mandates that 55% of the nation’s 25-to-35-year olds will be degree holders by the year 2025 (Lee & Rawls, 2010). But how do we accomplish the ambitious challenge and a necessary aspiration to elevate America’s status as a world leader in educational attainment among its citizenry? Innovative ideas and technologies that can counterbalance the barriers that threaten student success must be identified and advanced. The purpose of this article is to discuss the opportunity to leverage the marvel of online phenomena and technology in innovative ways to help students reach their full potential. Specifically, we introduce a new conceptual tool that replicates the power of social networking online matching services to link student learning preference with faculty instructional style.  相似文献   

Embedded Technical Expression: Code and the Leveraging of Functionality     

Matt Ratto 《The Information Society》2013,29(3):205-213

Abstract

In this article, I argue that a key problem for understanding the social ramifications of software is an implicit separation of software programs into two separate elements: expressive aspects, which are seen as socially driven and affectual, and functional aspects, understood as scientific and rational. In order to overcome this binary, I develop an alternative framework that examines the ways software expresses best practices, correct behaviors, and social organization. A key element of this framework is an understanding of software programs as simultaneously rhetorical and tangible objects. Given that Western society is dependent on sociotechnical systems in which software plays a crucial role, understanding the complex ways software expresses normative tasks, practices, and social orders is increasingly important.  相似文献   

A re-examination of the benefits of exercise for state body satisfaction: Consideration of individual difference factors     

Matt Fuller-Tyszkiewicz  Helen Skouteris  Marita Mccabe 《Journal of sports sciences》2013,31(7):706-713

Abstract

Although the link between exercise and body image is well documented, the considerable inter-individual variability in this relationship has been largely ignored. Therefore, the aim of the present study was to test the contributions of key body image and exercise-related moderators (age, body mass index (BMI), exercise frequency, trait body dissatisfaction, internalisation of appearance standards, and body surveillance tendencies) in predicting variability in the exercise-body satisfaction relationship. Thirty-seven undergraduate women completed a questionnaire containing the above trait-based measures and then carried a Personal Digital Assistant (PDA) for a 7-day period. Participants were instructed to use the PDA to self-report their state body satisfaction immediately following an exercise session and also when the PDA signalled at each of six random intervals throughout the day. Multilevel modelling revealed a bi-directional relationship between exercise and state body satisfaction. Moreover, post-exercise increases in state body satisfaction were strongest for individuals who were younger and engaged in regular exercise, and weakest for individuals with high BMI and/or the tendency to compare their appearance with others. These findings highlight potential limits on the efficacy of exercise-based therapy for body image disturbances.  相似文献   

The influence of` preseason training phase and training load on body composition and its relationship with physical qualities in professional junior rugby league players     

Nick Dobbin  Adrian Gardner  Matt Daniels  Craig Twist 《Journal of sports sciences》2013,31(24):2778-2786

ABSTRACT

This study investigated changes in body composition in relation to training load determined using RPE and duration (sRPE), and its relationship with physical qualities over a preseason period. Sixteen professional academy players (age = 17.2 ± 0.7 years; stature = 179.9 ± 4.9 cm; body mass = 88.5 ± 10.1 kg) participated in the study. Body composition was assessed before and after each training phase and physical qualities assessed at the start and end of preseason. Across the whole preseason period, skinfold thickness, body fat percentage and fat mass were most likely lower (ES = ?0.73 to ?1.00), and fat free mass and lean mass were likely to most likely higher (ES = 0.31 to 0.40). Results indicated that the magnitude of change appeared phase-dependent (ES = ?0.05 to ?0.85) and demonstrated large individual variability. Changes in physical qualities ranged from unclear to most likely (ES = ?0.50 to 0.64). Small to moderate correlations were observed between changes in body composition, and TL with changes in physical qualities. This study suggests training phase and TL can influence a player’s body composition; that large inter-participant variability exists; and that body composition and TL are related to the change in physical qualities.  相似文献

Abstract

The objective of this study was to provide anthropometric, physiological, and performance characteristics of an elite international handball team. Twenty-one elite handball players were tested and categorized according to their playing positions (goalkeepers, backs, pivots, and wings). Testing consisted of anthropometric and physiological measures of height, body mass, percentage body fat and endurance ([Vdot]O_2max), performance measures of speed (5, 10, and 30 m), strength (bench press and squat), unilateral and bilateral horizontal jumping ability, and a 5-jump horizontal test. Significant differences were found between player positions for some anthropometric characteristics (height and percentage body fat) but not for the physiological or performance characteristics. Strong correlations were noted between single leg horizontal jumping distances with 5-, 10-, and 30-m sprint times (r = 0.51–0.80; P < 0.01). The best predictors of sprint times were single leg horizontal jumping with the dominant leg and the distance measured for the 5-jump test, which when combined accounted for 72% of the common variance associated with sprint ability. In conclusion, performance abilities between positions in elite team-handball players appear to be very similar. Single leg horizontal jumping distance could be a specific standardized test for predicting sprinting ability in elite handball players.  相似文献   

Science assessments for all: Integrating science simulations into balanced state science assessment systems     

Edys S. Quellmalz  Michael J. Timms  Matt D. Silberglitt  Barbara C. Buckley 《科学教学研究杂志》2012,49(3):363-393

This article reports on the collaboration of six states to study how simulation‐based science assessments can become transformative components of multi‐level, balanced state science assessment systems. The project studied the psychometric quality, feasibility, and utility of simulation‐based science assessments designed to serve formative purposes during a unit and to provide summative evidence of end‐of‐unit proficiencies. The frameworks of evidence‐centered assessment design and model‐based learning shaped the specifications for the assessments. The simulations provided the three most common forms of accommodations in state testing programs: audio recording of text, screen magnification, and support for extended time. The SimScientists program at WestEd developed simulation‐based, curriculum‐embedded, and unit benchmark assessments for two middle school topics, Ecosystems and Force & Motion. These were field‐tested in three states. Data included student characteristics, responses to the assessments, cognitive labs, classroom observations, and teacher surveys and interviews. UCLA CRESST conducted an evaluation of the implementation. Feasibility and utility were examined in classroom observations, teacher surveys and interviews, and by the six‐state Design Panel. Technical quality data included AAAS reviews of the items' alignment with standards and quality of the science, cognitive labs, and assessment data. Student data were analyzed using multidimensional Item Response Theory (IRT) methods. IRT analyses demonstrated the high psychometric quality (reliability and validity) of the assessments and their discrimination between content knowledge and inquiry practices. Students performed better on the interactive, simulation‐based assessments than on the static, conventional items in the posttest. Importantly, gaps between performance of the general population and English language learners and students with disabilities were considerably smaller on the simulation‐based assessments than on the posttests. The Design Panel participated in development of two models for integrating science simulations into a balanced state science assessment system. © 2012 Wiley Periodicals, Inc.

Sources of differential participation rates in school science: the impact of curriculum reform     

Matt Homer  Jim Ryder  Jim Donnelly 《British Educational Research Journal》2013,39(2):248-265

School science courses have widely varying participation rates across a range of student characteristics. One of the stated aims of the 2006 Key Stage 4 science curriculum reforms in England was to improve social mobility and inclusion. To encourage students to study more science, this reform was followed by the introduction in 2008 of an entitlement to study the three separate sciences at Key Stage 4 for the more highly attaining students. This paper uses longitudinal national data over a five‐year period to investigate the extent and change of participation across science courses at KS4, focusing on student gender and socio‐economic status. It finds that whilst there is some evidence of a move towards a more equitable gender balance for some courses, there is as yet little evidence of substantial change in differential participation rates by socio‐economic status.  相似文献   

The influence of gravimetric moisture content on studded shoe–surface interactions in soccer     

James Clarke  Matt J. Carré 《Sports Engineering》2017,20(2):121-132

It is desirable for the studs of a soccer shoe to penetrate the sport surface and provide the player with sufficient traction when accelerating. Mechanical tests are often used to measure the traction of shoe–surface combinations. Mechanical testing offers a repeatable measure of shoe–surface traction, eliminating the inherent uncertainties that exist when human participant testing is employed, and are hence used to directly compare the performance of shoe–surface combinations. However, the influence specific surface characteristics has on traction is often overlooked. Examining the influence of surface characteristics on mechanical test results improves the understanding of the traction mechanisms at the shoe–surface interface. This allows footwear developers to make informed decisions on the design of studded outsoles. The aim of this paper is to understand the effect gravimetric moisture content has on the tribological mechanisms at play during stud–surface interaction. This study investigates the relationships between: the gravimetric moisture content of a natural sand-based soccer surface; surface stiffness measured via a bespoke impact test device; and surface traction measured via a bespoke mechanical test device. Regression analysis revealed that surface stiffness decreases linearly with increased gravimetric moisture content (p = 0.04). Traction was found to initially increase and then decrease with gravimetric moisture content. It was observed that: a surface of low moisture content provides low stud penetration and therefore reduced traction; a surface of high moisture content provides high stud penetration but also reduced traction due to a lubricating effect; and surfaces with moisture content in between the two extremes provide increased traction. In this study a standard commercially available stud was used and other studs may provide slightly different results. The results provide insight into the traction mechanisms at the stud–surface interface which are described in the paper. The variation between traction measurements shows the influence gravimetric moisture content will have on player performance. This highlights the requirement to understand surface conditions prior to making comparative shoe–surface traction studies and the importance of using a studded outsole that is appropriate to the surface condition during play.  相似文献
