COURSES AND INSTRUCTION AFFECTING CRITICAL THINKING

This study investigated how different types ofcourses and instructional techniques affect students'self-reported growth in critical thinking. Data aredrawn from the Cooperative Institutional Research Program's 1989 Follow-Up Survey of 24,837students who had first entered college as freshmen in1985. Results revealed that taking writing courses,interdisciplinary courses, history courses, sciencecourses, women's studies courses, math courses, foreignlanguage courses, ethnic studies courses, and enrollingin an honors program are each positively associated withselfreported growth in critical thinking. Moreover, self-reported growth in criticalthinking is positively related to having a papercritiqued by an instructor, conducting an independentresearch project, working on a group project, giving aclass presentation, and taking essay exams, butnegatively related to taking multiple-choice exams.Overall findings, however, suggest that the impact ofclassroom experiences on students' abilities to think critically is far weaker than one might expector hope.     

Optimum take-off angle in the long jump

In this study, we found that the optimum take-off angle for a long jumper may be predicted by combining the equation for the range of a projectile in free flight with the measured relations between take-off speed, take-off height and take-off angle for the athlete. The prediction method was evaluated using video measurements of three experienced male long jumpers who performed maximum-effort jumps over a wide range of take-off angles. To produce low take-off angles the athletes used a long and fast run-up, whereas higher take-off angles were produced using a progressively shorter and slower run-up. For all three athletes, the take-off speed decreased and the take-off height increased as the athlete jumped with a higher take-off angle. The calculated optimum take-off angles were in good agreement with the athletes' competition take-off angles.     

From Pleasure Rows and Plashing Sculls to Amateur Oarswomanship: The Evolution of Women’s Amateur Rowing in Britain

Abstract

This paper considers the emergence of amateur women’s rowing between the late nineteenth and early twentieth centuries, in light of contemporaneous social norms relating to gender and sport. It does not seek to identify a foundational point for women’s rowing, nor does it offer a comprehensive survey of the development of the sport over this period. Instead, it considers women’s rowing in three key contexts: women’s university colleges, at the end of the nineteenth century; the first women-only rowing club on the Thames, established in 1896 by Dr Frederick Furnivall; and the formation of a governing body for the women’s sport in 1923. Analysis of the conditions within the sport in these environments, and their implications, leads to more nuanced consideration of the women’s sport, and of gender as a normative social construct more widely. Discussion focuses on gendered influences on sporting behaviour, manifested in institutional regulation and hegemonic authority, and the intersection of class and gender.     

Robust fluidic connections to freestanding microfluidic hydrogels

Biomimetic scaffolds approaching physiological scale, whose size and large cellular load far exceed the limits of diffusion, require incorporation of a fluidic means to achieve adequate nutrient/metabolite exchange. This need has driven the extension of microfluidic technologies into the area of biomaterials. While construction of perfusable scaffolds is essentially a problem of microfluidic device fabrication, functional implementation of free-standing, thick-tissue constructs depends upon successful integration of external pumping mechanisms through optimized connective assemblies. However, a critical analysis to identify optimal materials/assembly components for hydrogel substrates has received little focus to date. This investigation addresses this issue directly by evaluating the efficacy of a range of adhesive and mechanical fluidic connection methods to gelatin hydrogel constructs based upon both mechanical property analysis and cell compatibility. Results identify a novel bioadhesive, comprised of two enzymatically modified gelatin compounds, for connecting tubing to hydrogel constructs that is both structurally robust and non-cytotoxic. Furthermore, outcomes from this study provide clear evidence that fluidic interconnect success varies with substrate composition (specifically hydrogel versus polydimethylsiloxane), highlighting not only the importance of selecting the appropriately tailored components for fluidic hydrogel systems but also that of encouraging ongoing, targeted exploration of this issue. The optimization of such interconnect systems will ultimately promote exciting scientific and therapeutic developments provided by microfluidic, cell-laden scaffolds.     

Interactive Kiosk at the Texas Tech University Libraries

The academic library, given its often privileged position on campus, is the information source that can include directional as well as general campus facts among the myriad of print and e-resources for reference. Also, an academic library's audiences can be quite varied and include prospective students or parents seeking more general knowledge of the building and the campus. Many times this need for information drives patrons to the library service desks. Sometimes, especially during the high-demand seasons of new student orientation and beginning of the fall semesters, the desk is so busy that many patrons will leave because they don't have the time to wait. To address this immediate need for information, Texas Tech University Libraries developed an interactive kiosk to provide general information for frequently asked questions in a more efficient, creative, and interactive way. The kiosk provides a fun method of satisfying a patron's information needs without the requirement of a staff member or the need to wait in line for help. The kiosk is available as long as the Library is open and provides a variety of useful answers to general questions, as well as facts about the Library.     

Media Marathoning and Health Coping

This study uses Grounded Theory to analyze interviews with a dozen individuals who media marathoned while going through a health struggle. The analysis addresses five major themes: engaging in escapism that enables emotional and avoidance coping, regulating cognitive expenditure by embracing challenging or comforting content, being still to heal the body, reducing emotional and cognitive strain by engaging a continuous narrative, and tapering from the marathon when feeling better. Findings suggest that media marathoning can offer beneficial cognitive, emotional, and physical regulatory opportunities for those dealing with health struggles. Furthermore, media marathoning when dealing with a health concern is a strategic and active coping strategy that has potential health benefits.     

“We bleed for female empowerment”: mediated ethics,commodity feminism,and the contradictions of feminist politics

Discourses of female empowerment are increasingly prominent within ethical capitalism, which seeks to remedy global crises with private-sector solutions and their commodities. This article examines the intersecting manifestations of female empowerment, commodity activism, and ethical capitalism with case studies on Born Free Africa, a fashion collection combatting mother-to-child HIV transmission, and THINX, which sells “period-proof” panties. Each company articulates empowerment through a binary between the Western feminist savior and “in-need” woman of the global south. This article argues that this iteration of empowerment not only reinforces logics of neo-colonial capitalism, but also masks disciplinary regimes for individual feminine subjects.
