TO THE POINT: HOW MANAGEMENT FACULTY USE POWERPOINT SLIDES AND QUIZZES

This exploratory study examines U.S. management faculty usage of two types of supplements: PowerPoint (PPT) slides and quizzes. Results suggest the majority (67%) of experienced management faculty frequently employ PowerPoint in their classes. However, they do not see PPT basic slides provided by the publisher as very central to getting their message across. In using PPT they tend to personalize publisher slides to cover issues discussed in class and to embellish slides with visuals and videos for interest. Primarily they encourage their students to use PowerPoint slides provided on the instructor’s website to review lectures and chapter material to prepare for exams. Half of our study’s management professors used quizzes sparingly or not at all. When quizzes were used, professors developed their questions more often based on material presented in class as well as from the text. Further research investigating the reasoning behind faculty’s choices is warranted

STICKER SHOCK: MANAGEMENT PROFESSORS’PERSPECTIVES ON THE RISING COSTS OF COLLEGETEXTBOOKS

This study uses Internet survey methodology to target management instructors’ views on the cost of textbooks and the strategies that might be exercised by universities, publishers, and legislatures to control cost increases. From a random sample of 2,893 management professors selected, using university websites, from universities throughout the United States, 228 provided useable responses. Findings suggest that management instructors, particularly those with years of experience, acknowledge the concerns their students have over high textbook prices. They are willing to have legislation enacted to force changes in the marketing of the textbooks by publishers, but they do not want university policies that unduly (from their perspective) restrict their choices for texts. Nor are they in favor of possible publisher cost saving strategies that appear to add administrative burdens on faculty involved in the adoption process. Future research should include investigating techniques for reducing the rising costs of textbooks

Southern Ocean bottom water characteristics in CMIP5 models

Southern Ocean deep water properties and formation processes in climate models are indicative of their capability to simulate future climate, heat and carbon uptake, and sea level rise. Southern Ocean temperature and density averaged over 1986–2005 from 15 CMIP5 (Coupled Model Intercomparison Project Phase 5) climate models are compared with an observed climatology, focusing on bottom water. Bottom properties are reasonably accurate for half the models. Ten models create dense water on the Antarctic shelf, but it mixes with lighter water and is not exported as bottom water as in reality. Instead, most models create deep water by open ocean deep convection, a process occurring rarely in reality. Models with extensive deep convection are those with strong seasonality in sea ice. Optimum bottom properties occur in models with deep convection in the Weddell and Ross Gyres. Bottom Water formation processes are poorly represented in ocean models and are a key challenge for improving climate predictions

United Nations Declaration on the Rights of Indigenous Peoples, 2007 * Prepared for the International Peace Research Association

Abstract This paper seeks to understand the concept, justification, and operation of co-management. Furthermore, we like to explore how indigenous peoples may take part in the management of natural resource through the mechanism of co-management. Finally, we will assess how co-management may be applied in Taiwan and what potential barriers may be in the way. Article 18 Indigenous peoples have the right to participate in decision-making in matters which would affect their rights, through representatives chosen by themselves in accordance with their own procedures, as well as to maintain and develop their own indigenous decision-making institutions. Article 32 1. Indigenous peoples have the right to determine and develop priorities and strategies for the development or use of their lands or territories and other resources. 2. States shall consult and cooperate in good faith with the indigenous peoples concerned through their own representative institutions in order to obtain their free and informed consent prior to the approval of any project affecting their lands or territories and other resources, particularly in connection with the development, utilization or exploitation of their mineral, water or other resources

Hair cortisol as a biomarker of stress in mindfulness training for smokers.

OBJECTIVES: Stress is a well-known predictor of smoking relapse, and cortisol is a primary biomarker of stress. The current pilot study examined changes in levels of cortisol in hair within the context of two time-intensity matched behavioral smoking cessation treatments: mindfulness training for smokers and a cognitive-behavioral comparison group. PARTICIPANTS: Eighteen participants were recruited from a larger randomized controlled trial of smoking cessation. OUTCOME MEASURES: Hair samples (3 cm) were obtained 1 month after quit attempt, allowing for a retrospective analysis of hair cortisol at preintervention and post-quit attempt time periods. Self-reported negative affect was also assessed before and after treatment. INTERVENTION: Both groups received a 7-week intensive intervention using mindfulness or cognitive-behavioral strategies. RESULTS: Cortisol significantly decreased from baseline to 1 month after quit attempt in the entire sample (d=-0.35; p=.005). In subsequent repeated-measures analysis of variance models, time by group and time by quit status interaction effects were not significant. However, post hoc paired t tests yielded significant pre-post effects among those randomly assigned to the mindfulness condition (d=-0.48; p=.018) and in those abstinent at post-test (d=-0.41; p=.004). Decreased hair cortisol correlated with reduced negative affect (r=.60; p=.011). CONCLUSIONS: These preliminary findings suggest that smoking cessation intervention is associated with decreased hair cortisol levels and that reduced hair cortisol may be specifically associated with mindfulness training and smoking abstinence. RESULTS support the use of hair cortisol as a novel objective biomarker in future research

Caveolae-dependent and -independent uptake of albumin in cultured rodent pulmonary endothelial cells

Although a critical role for caveolae-mediated albumin transcytosis in pulmonary endothelium is well established, considerably less is known about caveolae-independent pathways. In this current study, we confirmed that cultured rat pulmonary microvascular (RPMEC) and pulmonary artery (RPAEC) endothelium endocytosed Alexa488-labeled albumin in a saturable, temperature-sensitive mode and internalization resulted in co-localization by fluorescence microscopy with cholera B toxin and caveolin-1. Although siRNA to caveolin-1 (cav-1) in RPAEC significantly inhibited albumin uptake, a remnant portion of albumin uptake was cav-1-independent, suggesting alternative pathways for albumin uptake. Thus, we isolated and cultured mouse lung endothelial cells (MLEC) from wild type and cav-1-/- mice and noted that ∼ 65% of albumin uptake, as determined by confocal imaging or live cell total internal reflectance fluorescence microscopy (TIRF), persisted in total absence of cav-1. Uptake of colloidal gold labeled albumin was evaluated by electron microscopy and demonstrated that albumin uptake in MLEC from cav-1-/- mice was through caveolae-independent pathway(s) including clathrin-coated pits that resulted in endosomal accumulation of albumin. Finally, we noted that albumin uptake in RPMEC was in part sensitive to pharmacological agents (amiloride [sodium transport inhibitor], Gö6976 [protein kinase C inhibitor], and cytochalasin D [inhibitor of actin polymerization]) consistent with a macropinocytosis-like process. The amiloride sensitivity accounting for macropinocytosis also exists in albumin uptake by both wild type and cav-1 -/- MLEC. We conclude from these studies that in addition to the well described caveolar-dependent pulmonary endothelial cell endocytosis of albumin, a portion of overall uptake in pulmonary endothelial cells is cav-1 insensitive and appears to involve clathrin-mediated endocytosis and macropinocytosis-like process. © 2013 Li et al
