An Innovative Approach to Teacher Retention

Among the many challenges educational leaders are facing, teacher attrition is most paramount. Not only are teachers with less than five years of experience leaving the field at alarming rates, but the number of teachers with twenty or more years of experience has also decreased by 10% since 2000. Teachers who leave the field often site a lack of support as their primary source of frustration. While school districts across the nation have made efforts to address teacher attrition, induction programs are often managed at the district level and completed solely out of compliance. After reviewing the literature on teacher retention, attrition, and induction programs, the researchers developed a NewTeacherRetention.com. Unlike most new teacher programs, the website offers support at the school level. Components include Professional Development, Teacher Resources, and Exceptional Education. Most importantly, the website\u27s goal is to offer specific support to new teachers. Educators were recruited and asked to peruse the various components of the NewTeacherRetention.com. After reviewing the website, participants were then asked to evaluate its effectiveness by completing a brief survey, comprised of demographic, Likert Scale, and open-ended questions. Participants responded favorably (agree or strongly agree) to 88.9% of the Likert Scale questions. The survey results lead the researchers to conclude a resource such as NewTeacherRetention.com can be utilized by a school or school district to help lower teacher attrition

General Solution of the Consistency Equation

We produce the general solution of the Wess-Zumino consistency condition for gauge theories of the Yang-mills type, for any ghost number and form degree. We resolve the problem of the cohomological independence of these solutions. In other words we fully describe the local version of the cohomology of the BRS operator, modulo the differential on space--time. This in particular includes the presence of external fields and non--trivial topologies of space--time.Comment: 11 pages, Latex file, PAR-LPTHE 92/1

The Benefits of a Challenge Approach on Match Day: Investigating Cardiovascular Reactivity in Professional Academy Soccer Players

This study assessed physiological (cardiovascular) and psychological (confidence, control, and approach focus) data in professional academy soccer players prior to performance in competitive matches. A challenge state is characterised by an increase in cardiac output (CO), and a decrease in total peripheral vascular resistance (TPR). Data were collected from 37 participants, with 19 of these providing data on two separate occasions. Performance was measured using coach and player self-ratings. Challenge reactivity was positively, and significantly, associated with performance. Participants who demonstrated blunted cardiovascular (CV) responses performed significantly worse than participants who displayed either challenge or threat reactivity. There was mixed consistency in CV reactivity for those participants whose data were collected on more than one occasion, suggesting that some participants responded differently across the competitive matches. The association between self-report data and CV responses was weak. This study supports previous research demonstrating that challenge reactivity is associated with superior performance

A Vision for the Systematic Monitoring and Improvement of the Quality of Electronic Health Data

In parallel with the implementation of information and communications systems, health care organizations are beginning to amass large-scale repositories of clinical and administrative data. Many nations seek to leverage so-called Big Data repositories to support improvements in health outcomes, drug safety, health surveillance, and care delivery processes. An unsupported assumption is that electronic health care data are of sufficient quality to enable the varied use cases envisioned by health ministries. The reality is that many electronic health data sources are of suboptimal quality and unfit for particular uses. To more systematically define, characterize and improve electronic health data quality, we propose a novel framework for health data stewardship. The framework is adapted from prior data quality research outside of health, but it has been reshaped to apply a systems approach to data quality with an emphasis on health outcomes. The proposed framework is a beginning, not an end. We invite the biomedical informatics community to use and adapt the framework to improve health data quality and outcomes for populations in nations around the world

Effects of Grazing Crop Residues of bt-Corn Hybrids on Performance of Pregnant Beef Cows

To determine the effects of grazing crop residues from bt-corn hybrids on performance of pregnant beef cows, one non bt-corn hybrid (Pioneer 3489) and three bt-corn hybrids (Pioneer 34RO7 and Novartis NX6236 with the Yieldgard event and Novartis N64Z4 with the Knockout event) were planted in duplicate 7.1-acre fields in 1998 and 1999. Thirty Angus x Charolais x Simmental cows in midgestation were allotted amongst two drylots or the eight crop residue fields to strip-graze for 126 days. Cow body condition scores were visually estimated biweekly and alfalfa-grass hay was supplemented to maintain a mean body condition score of 5 on a 9-point scale. Corn stalks and ear shanks from Pioneer 3489 corn had a higher (P\u3c.05) infestation of corn borers than did any of the bt-corn hybrids. Mean yields of harvested grain, dropped ears or grain, or crop residue dry matter (DM) or organic matter (OM) over the two years were not significantly affected by corn hybrid, but values for bt-corn hybrids were not equivalent to the non bt-corn hybrid. At grazing initiation, crop residues from Novartis NX6236 and N64Z4 had higher (P\u3c.05) concentrations of in vitro digestible organic matter (IVOMD) and lower (P\u3c.05) concentrations of acid detergent fiber (ADF) and acid detergent lignin (ADL) than Pioneer 3489 or Pioneer 34RO7. Rates of change in the concentrations of IVOMD, neutral detergent fiber (NDF), ADF, ADL and crude protein (CP) over winter were not significantly affected by corn hybrid, but rates for bt-corn hybrids were not equivalent to non bt-corn hybrids. Forage selected during feeding by fistulated steers did not differ in IVOMD concentrations between winter feeding systems or NDF, ADF, CP or acid detergent insoluble nitrogen (ADIN) concentrations between corn hybrids. Intakes of forage digestible DM, NDF and ADF did not differ between winter feeding systems, but were not equivalent to the non bt-corn hybrid. Mean amounts of hay required to maintain body condition score of cows maintained in a drylot were greater than cows grazing crop residues (3199 vs 825 lb DM/cow), but did not differ between corn hybrids

Measuring Population Health Using Electronic Health Records: Exploring Biases and Representativeness in a Community Health Information Exchange

Assessment is a core function of public health. Comprehensive clinical data may enhance community health assessment by providing up-to-date, representative data for use in public health programs and policies, especially when combined with community-level data relevant to social determinants. In this study we examine routinely collected and geospatially-enhanced EHR data to assess population health at various levels of geographic granularity available from a regional health information exchange. We present preliminary findings and discuss important biases in EHR data. Future work is needed to develop methods for correcting for those biases to support routine epidemiology work of public health

Remarks on the renormalization of gauge invariant operators in Yang-Mills theory

A simplified proof of a theorem by Joglekar and Lee on the renormalization of local gauge invariant operators in Yang-Mills theory is given. It is based on (i) general properties of the antifield-antibracket formalism; and (ii) well-established results on the cohomology of semi-simple Lie algebras.Comment: 12 pages in LaTex, ULB-PMIF/93-0
