Class Attendance and Students’ Evaluations of Teaching: Do No-Shows Bias Course Ratings and Rankings?

Background: Many university departments use students’ evaluations of teaching (SET) to compare and rank courses. However, absenteeism from class is often nonrandom and, therefore, SET for different courses might not be comparable. Objective: The present study aims to answer two questions. Are SET positively biased due to absenteeism? Do procedures, which adjust for absenteeism, change course rankings? Research Design: The author discusses the problem from a missing data perspective and present empirical results from regression models to determine which factors are simultaneously associated with students’ class attendance and course ratings. In order to determine the extent of these biases, the author then corrects average ratings for students’ absenteeism and inspect changes in course rankings resulting from this adjustment. Subjects: The author analyzes SET data on the individual level. One or more course ratings are available for each student. Measures: Individual course ratings and absenteeism served as the key outcomes. Results: Absenteeism decreases with rising teaching quality. Furthermore, both factors are systematically related to student and course attributes. Weighting students’ ratings by actual absenteeism leads to mostly small changes in ranks, which follow a power law. Only a few, average courses are disproportionally influenced by the adjustment. Weighting by predicted absenteeism leads to very small changes in ranks. Again, average courses are more strongly affected than courses of very high or low in quality. Conclusions: No-shows bias course ratings and rankings. SET are more appropriate to identify high- and low-quality courses than to determine the exact ranks of average courses

Enhancing disabilities: transhumanism under the veil of inclusion?

Technological developments for disabled athletes may facilitate their competition in standard elite sports. They raise intriguing philosophical questions that challenge dominant notions of body and normality. The case of 'bladerunner' Oscar Pistorius in particular is used to illustrate and defend 'transhumanist' ideologies that promote the use of technology to extend human capabilities. Some argue that new technologies will undermine the sharp contrast between the athlete as a cultural hero and icon and the disabled person that needs extra attention or care; the one exemplary of the peak of normality, human functioning at its best, the other representing a way of coping with the opposite. Do current ways of classification do justice to the performances of disabled athletes? The case of Oscar Pistorius will be used to further illustrate the complexities of these questions, in particular when related to notions of normality and extraordinary performances. Pistorius' desire to become part of 'normal' elite sport may be interpreted as an expression of a right to 'inclusion' or 'integration', but at the same time it reproduces new inequalities and asymmetries between performances of able and dis-abled athletes: we propose that if one accepts that Pistorius should compete in the 'regular' Olympic Games, this would paradoxically underline the differences between able and disabled and it would reproduce the current order and hierarchy between able and disabled bodies. © 2010 Informa UK, Ltd

Posthuman disability studies

This article explores the human through critical disability studies and the theories of Rosi Braidotti. We ask: What does it mean to be human in the twenty-first century and in what ways does disability enhance these meanings? In addressing this question we seek to work through entangled connections of nature, society, technology, medicine, biopower and culture to consider the extent to which the human might be an outdated phenomenon, replaced by Braidotti’s posthuman condition. We then introduce disability as a political category, an identity and a moment of relational ethics. Critical disability studies, we argue, are perfectly at ease with the posthuman because disability has always contravened the traditional classical humanist conception of what it means to be human. Disability also invites a critical analysis of the posthuman. We examine the ways in which disability and posthuman work together, enhancing and complicating one another in ways that raise important questions about the kinds of life and death we value. We consider three of Braidotti’s themes in relation to disability: (i) Life beyond the self: Rethinking enhancement; (ii) Life beyond the species: Rethinking animal; (iii) Life beyond death: Rethinking death. We conclude by advocating a posthuman disability studies that responds directly to contemporary complexities around the human while celebrating moments of difference and disruption

Biomechanical analyses of the performance of Paralympians: From foundation to elite level

Biomechanical analysis of sport performance provides an objective method of determining performance of a particular sporting technique. In particular, it aims to add to the understanding of the mechanisms influencing performance, characterization of athletes, and provide insights into injury predisposition. Whilst the performance in sport of able-bodied athletes is well recognised in the literature, less information and understanding is known on the complexity, constraints and demands placed on the body of an individual with a disability. This paper provides a dialogue that outlines scientific issues of performance analysis of multi-level athletes with a disability, including Paralympians. Four integrated themes are explored the first of which focuses on how biomechanics can contribute to the understanding of sport performance in athletes with a disability and how it may be used as an evidence-based tool. This latter point questions the potential for a possible cultural shift led by emergence of user-friendly instruments. The second theme briefly discusses the role of reliability of sport performance and addresses the debate of two-dimensional and three-dimensional analysis. The third theme address key biomechanical parameters and provides guidance to clinicians, and coaches on the approaches adopted using biomechanical/sport performance analysis for an athlete with a disability starting out, to the emerging and elite Paralympian. For completeness of this discourse, the final theme is based on the controversial issues on the role of assisted devices and the inclusion of Paralympians into able-bodied sport is also presented. All combined, this dialogue highlights the intricate relationship between biomechanics and training of individuals with a disability. Furthermore, it illustrates the complexity of modern training of athletes which can only lead to a better appreciation of the performances to be delivered in the London 2012 Paralympic Games

Are Better Workers Also Better Humans? On Pharmacological Cognitive Enhancement in the Workplace and Conflicting Societal Domains

The article investigates the sociocultural implications of the changing modern workplace and of pharmacological cognitive enhancement (PCE) as a potential adaptive tool from the viewpoint of social niche construction. We will attempt to elucidate some of the sociocultural and technological trends that drive and influence the characteristics of this specific niche, and especially to identify the kind of capabilities and adaptations that are being promoted, and to ascertain the capabilities and potentialities that might become diminished as a result. In this context, we will examine what PCE is, and how and why it might be desirable as a tool for adaptation within the workplace. As human beings are, or at least should be allowed to be, more than merely productive, able-bodied and able-minded workers, we will further examine how adaptation to the workplace niche could result in problems in other domains of modern societal life that require the same or other cognitive capabilities. In this context we will also focus on the concept of responsibility and how it pertains to PCE and the modern workplace niche. This will shed some light on the kind of trends related to workplace niche construction, PCE and capability promotion that we can expect in the future, and on the contexts in which this might be either beneficial or detrimental to the individual as a well-rounded human being, and to other members of society

Robots in education and care of children with developmental disabilities : a study on acceptance by experienced and future professionals

Research in the area of robotics has made available numerous possibilities for further innovation in the education of children, especially in the rehabilitation of those with learning difficulties and/or intellectual disabilities. Despite the scientific evidence, there is still a strong scepticism against the use of robots in the fields of education and care of people. Here we present a study on the acceptance of robots by experienced practitioners (specialized in the treatment of intellectual disabilities) and university students in psychology and education sciences (as future professionals). The aim is to examine the factors, through the Unified Theory of Acceptance and Use of Technology (UTAUT) model, that may influence the decision to use a robot as an instrument in the practice. The overall results confirm the applicability of the model in the context of education and care of children, and suggest a positive attitude towards the use of the robot. The comparison highlights some scepticism among the practitioners, who perceive the robot as an expensive and limited tool, while students show a positive perception and a significantly higher willingness to use the robot. From this experience, we formulate the hypothesis that robots may be accepted if more integrated with standard rehabilitation protocols in a way that benefits can outweigh the costs

Ecohealth Through an Ability Studies and Disability Studies Lens

Purpose – The goal of this chapter is to cultivate interest in the societal dynamic of ability expectations and ableism, a dynamic first thematized by the disabled people rights movement but which is also broadly applicable to the study of the relationship between humans, animals, and environments. Another aim of this chapter is to think about disabled people within ecosystem approaches to health through the ableism framework and to show that insights gained from disability studies are applicable to a broader study of health within contexts of environmental degradation. Building from this approach, the reader is invited to consider the utility of the conceptual framework of eco-ability ‘‘expectations’’ and eco-ableism as a way to understand health within coupled social- ecological systems. Methodology/approach – This chapter uses an ability expectation and ableism lens and a disability studies and ability studies approach to analyze the relationship between humans, animals, and environments. Findings – Certain ability expectations and ableism are responsible for (a) the invisibility of disabled people in ecological health discourses; (b) the standoff between anthropocentric and biocentric/ecocentric approaches to health; and (c) the application of scientific and technological advancements to address problems arising out of current relationships between humans, animals, and environments. Originality/value of chapter – The reader is introduced to the concepts of ableism and eco-ableism, which have not yet been used in EcoHealth discourses and flags the need for further engagement with disability issues within the field.Ye
