A Comparison of the Achievement of Selected Students in High School Social Studies Taught by the Team Teaching Method and the Traditional Method

It was the purpose of this study to compare learning outcomes of students taught by traditional methods with that of students instructed by certain selected arrangements of resources commonly associated with the teaching team approach

Economics of Alternative Crop Production in Arid Regions

As water resources in arid regions decline, agricultural producers are encouraged to adopt water conserving strategies. The implementation of alternative low-water use crops is one option, but is it economically feasible? Data on current and alternative crops for this study include enterprise budgets, producer interviews, and field trials in Northwestern Nevada, USA. We use WinEPIC, a Windows-based version of the EPIC model, which synthesizes both agronomics and economics, to model yields and returns of alternative crop production under differing irrigation levels. Risk analysis or the distribution of net returns to alternative crop production is also examined. This study determined that there are alternative crops that could be feasibly substituted for alfalfa and reduce water use by at least one-half while providing net returns that meet or exceed returns from alfalfa and keep producers profitable in agriculturealternative crops, arid regions, economic feasibility, irrigation, WinEPIC,

X-ray Emission from Extragalactic Jets

This review focuses on the X-ray emission processes of extra-galactic jets on scales resolvable by the sub arcsec resolution of the Chandra X-ray Observatory. It is divided into 4 parts. The introductory chapter reviews the classical problems for jets, as well as those associated directly with the X-ray emission. Throughout this section, we deal with the dualisms of low powered radio sources versus high powered radio galaxies and quasars; synchrotron models versus inverse Compton models; and the distinction between the relativistic plasma responsible for the received radiation and the medium responsible for the transport of energy down the jet. The second part collects the observational and inferred parameters for the currently detected X-ray jets and attempts to put their relative sizes and luminosities in perspective. In part 3, we first give the relevant radio and optical jet characteristics, and then examine the details of the X-ray data and how they can be related to various jet attributes. The last section is devoted to a critique of the two non-thermal emission processes and to prospects for progress in our understanding of jets.Comment: This is a version of a review article to be published (2006 Sep) in the Annual Reviews of Astronomy and Astrophysics, vol. 44, p. 463. 8 of the 12 figures have been removed from the article and are provided as separate jpg files to conserve space.

Three- versus four-factor prothrombin complex concentrate for the reversal of warfarin-induced bleeding

Objective: The objective of this study was to evaluate the effectiveness of 3-factor prothrombin complex concentrate (3F-PCC) compared to 4-factor PCC (4F-PCC) in warfarin-associated bleeding. Methods: This multicenter, retrospective, cohort study analyzed data from patients admitted between May 2011 and October 2014 who received PCC for warfarin-associated bleeding. The primary outcome was the rate of international normalized ratio (INR) normalization, defined as an INR ≤1.3, after administration of 3F-PCC compared to 4F-PCC. Other variables of interest included the incidence of additional reversal agents, new thromboembolic events, and mortality. Results: A total of 134 patients were included in the analysis. The average dose of PCC administered was 24.6 ± 9.3 units/kg versus 36.3 ± 12.8 units/kg in the 3F-PCC and 4F-PCC groups, respectively, P < 0.001. Baseline INR in the 3F-PCC and 4F-PCC groups was 3.61 ± 2.3 and 6.87 ± 2.3, respectively P < 0.001. 4F-PCC had a higher rate of INR normalization at first INR check post-PCC administration compared to 3F-PCC (84.2% vs. 51.9%, P = 0.0001). Thromboembolic events, intensive care unit and hospital length of stay, and mortality were similar among both groups. Conclusion: The use of 4F-PCC leads to a more significant reduction in INR compared to 3F-PCC though no difference in mortality or length of stay was observed. Thromboembolism rates were similar among both groups

Influential Article Review - Asian HR Analysis on Methodological Options

This paper examines human resources management. We present insights from a highly influential paper. Here are the highlights from this paper: A twenty-year study of the Human Resource (HR) practices– outcome relationship has found that more rigorous methodologies have been adopted over time. However, several problematic features such as cross-sectional, single-informant, and single-level designs continue to be adopted (Bainbridge et al., Human Resource Management, 2016). Responding to calls for increased contextualization of research by investigating the relationship between the location of data collection and the methodological choices of researchers, this study answers the question “How unique are the methodological choices of HR research conducted in Asia?” Applying content analysis to 241 published articles, we compare internal, external, construct and statistical conclusion validity of studies collected in North America (n=66), Europe (n=95) and Asia (n=80, including 57 studies from China). Results show that despite similarities in cross-sectional, single-informant and single-level designs across regions, research conducted in Asia is mainly undertaken via field studies, using subjective outcome measures at the organizational level, following a post-predictive design. In addition, studies from Asia are more recent, and show a shorter time gap between data collection and publication. Theoretical and practical implications embedded in the dynamic context of Asia in general, and China more specifically are discussed. For our overseas readers, we then present the insights from this paper in Spanish, French, Portuguese, and German
