Bursting with Potential: Mixing a Media Specialist’s Palette

School media specialists must be teachers, leaders, and advocates for reading, inquiry, and learning. Partnering with classroom teachers, they must design and implement curriculum and instruction that prepare young citizens for a life that requires thinking, inquiry, problem-solving and ethical behavior. These experiences provide the foundation for all content-area learning. In order to be prepared for a constantly changing environment, professionals need to revisit, reframe, and re-imagine knowledge, skills, attitudes, and dispositions. In this article, the author presents six tools that form a media specialist’s palette to help them meet these challenges. Along with these tools, specific ideas and examples are presented that illustrate how this palette of tools can be used in the media center on a daily basis.     

VO2 prediction and cardiorespiratory responses during underwater treadmill exercise

We compared cardiorespiratory responses to exercise on an underwater treadmill (UTM) and land treadmill (LTM) and derived an equation to estimate oxygen consumption (VO2) during UTM exercise. Fifty-five men and women completed one LTM and five UTM exercise sessions on separate days. The UTM sessions consisted of chest-deep immersion, with 0, 25, 50, 75, and 100% water-jet resistance. All session treadmill velocities increased every 3 min from 53.6 to 187.8 m x min(-1). Cardiorespiratory responses were similar between LTM and UTM when jet resistance for UTM was 50%. Using multiple regression analysis, weight-relative VO2 could be estimated as: VO2 (mLO2 c kg(-1) x min(-1)) = 0.19248 x height (cm) + 0.17422 x jet resistance (% max) + 0.14092 x velocity (m x min(-1)) -0.12794 x weight (kg)-27.82849, R2 = .82. Our data indicate that similar LTM and UTM cardiorespiratory responses are achievable, and we provide a reasonable estimate of UTM VO2.     

Healthy Birth Practice #3: Bring a Loved One,Friend, or Doula for Continuous Support

All women should be allowed and encouraged to bring a loved one, friend, or doula to their birth without financial or cultural barriers. Continuous labor support offers benefits to mothers and their babies with no known harm. This article is an updated evidence-based review of the “Lamaze International Care Practices that Promote Normal Birth, Care Practice #3: Continuous Labor Support,” published in The Journal of Perinatal Education, 16(3), 2007.     

Vocational education and race in the Chicago public schools: Three historical case studies and implications for current reform

Three vocational high schools provide illustrative and contrasting histories in terms of African-American education and economic opportunity. Washburne Trade School reinforced trade union exclusion of African-Americans, and since integration in the 1960s has been abandoned by most of the powerful unions. Dunbar Vocational High School directed African-Americans into the lower-paying trades, but has lost the economic base that the ghetto once provided. Chicago Vocational School prepared the white working class for industrial jobs, but integration and re-segregation has coincidentally seen the erosion of Chicago's manufacturing base. These schools are compared in the economic, political, and cultural contexts of past and present. It is proposed that an integrated strategy for the reform of vocational education is necessary for these schools to adapt to economic change in the present and future.     

Comparability of Scores From Performance Assessments

Why is comparability of forms important for performance assessments? Can traditional methods of form equating be used? What problems are likely to arise in equating? Can standards generalize across forms?     

Information needs of specialist healthcare professionals: a preliminary study based on the West of Scotland Colorectal Cancer Managed Clinical Network

OBJECTIVES: Funded by Research in the Workplace Award (RIWA) 2001, the study investigated the information needs and use of NHS library services by members of the West of Scotland Colorectal Cancer Managed Clinical Network (MCN), a single subject, cross boundary, multi-professional organization. METHOD: A postal questionnaire sent out in October 2002 was returned by 100 members and follow-up interviews were held in March 2003 with 11 of the respondents. The questions related to access to resources, library services such as literature searches, current awareness and training. They also explored the use of electronic resources and the Internet. RESULTS: Respondents were mainly hospital doctors and a few nurses from across five health boards. Most had access to a library, although not all made use of it, possibly an indication of the need for improved communications between librarians and health-care staff. Generally, research and professional development were reported as reasons for needing cancer information, but on further investigation the motivation to conduct literature searches was more related to patient care. Examples included treatment of unusual cases, locating information for patients and identifying guidelines. There are indications of unmet needs for local contact information and evaluated patient information. CONCLUSION: Development of a cancer portal within the NHS Scotland e-Library available from May 2004 based on the Managed Knowledge Network (MKN) concept is attempting to address many of the issues raised in the survey, including inequities of access to services and signposting to a variety of types of information.     

Automatic detection of collisions in elite level rugby union using a wearable sensing device

Elite rugby union teams currently employ the latest technology to monitor and evaluate the physical demands of training and games on their players. Tackling has been shown to be the most common cause of injury in rugby union, yet current player monitoring technology does not effectively evaluate player tackling measurements. Currently, to evaluate measurements specific to player tackles, a time-consuming manual analysis of player sensor data and video footage is required. The purpose of this work is to investigate tackle modeling techniques which can be utilised to automatically detect player tackles and collisions using sensing technology already being used by elite international and club level rugby union teams. This paper discusses issues relevant to automatic tackle analysis, describes a technique to detect tackles using sensing data and validates the technique by comparing automatically detected collisions to manually labeled collisions using data from elite club and international level players. The results of the validation show that the system is able to consistently identify collisions with very few false positives and false negatives, achieving a recall and precision rating of 0.933 and 0.958, respectively. The aim is that the automatically detected tackles can provide coaching, medical and strength and conditioning staff with objective tackle-specific measurements, in real time, which can be used in injury prevention and rehabilitation strategies.
