La expresión facial en los ciegos congénitos

Resumen

El presente informe analiza la expresión emocional de los ciegos congénitos mediante una codificación muscular de los movimientos faciales. Esta expresión, de carácter más involuntario, es semejante a la de los videntes. En cambio, los sujetos invidentes tienen una expresividad menor y menos diferenciada en las poses voluntarias. Los resultados, que confirman los hallazgos de autores anteriores, apoyan la existencia de dos fuentes de información en el desarrollo emocional: una de naturaleza genética, que explicaría las semejanzas en la expresión emocional o involuntaria, y otra ambiental, que daría cuenta de las diferencias en la expresión voluntaria. Por último, se plantean las consecuencias de este trabajo para las distintas disciplinas psicológicas.     

ACADEMIC ADMINISTRATORS AND FACULTY RETIREMENT IN A NEW ERA

ABSTRACT

More than a decade ago, as the end of mandatory retirement for faculty approached, many academic administrators were concerned about its negative impact on their institutions. With the assistance of a variety of incentives put in place to encourage voluntary retirement, a significant number of senior faculty retired during the 1990s. Now, the looming loss of millions of “baby boomer” faculty requires rethinking faculty retirement. Administrators have two urgent issues to address: defining and maintaining a balance of junior and senior faculty, and designing and implementing effective retirement programs for this new generation of aging faculty. Important differences between previous and future generations of faculty suggest that retirement programs that worked in the past may no longer be effective for the institution—and may not appeal to the faculty. Federal and state governments, businesses, and organizations are preparing to respond to the forthcoming biggest wave of retirement in our country's history. Academic administrators, who pioneered phased-retirement programs, will want to stay on top of this wave too.     

Coping with [R]evolution in Online Games: Vulnerability and Resilience Responses to Change in MMO Game Expansions

Massively multiplayer online games (MMOs) often introduce new content and mechanics to increase player retention and enjoyment. Drawing on theories of socioecological risk response, this exploratory study examines players’ in situ responses to these changes by analyzing patterns in public, in-game chat across 3 game expansions. Analysis reveals that a) change facilitates agenda setting in player chat, b) vulnerability and resilience expressions highlight tensions in player and game agencies, and c) increased semantic distance between the game and the “real” helps cope with game changes. In addition, sociotechnical affordances of MMO environments could be a mechanism for coping with change, more generally.     

Legends in Science: from Boom to Bust

In biology and medicine, a scientist’s legend is most commonly determined by their sphere of influence, either on surrounding peers, on clients in the case of medical practitioners, or on the wider scientific public in the case of research scientists. A scientific paper still constitutes the most effective portal through which ideas, knowledge and opinions can be shared among academics and scholars. Thus, legends in science are built upon a scientist’s published literature. Legend was always assumed to be safe in its final form, i.e., a published paper. Yet, a powerful movement of post-publication peer review has begun to identify that not all has been well with the vetting process that led to the publication of a tranche of the scientific literature, and that editorial oversight and weakness has prevailed in a number of cases, leading to retractions and a more critical re-assessment of the literature. One could say that the half-life of a scientific paper has only just begun once it is published. Within this context of science publishing that has given a sense of false security, legends may evolve from boom to bust within the space of weeks or even months. The legendary status of a scientist is therefore no longer safe if there are hidden or undiscovered errors, fraud or misconduct.     

Towards a critical re-conceptualization of the purpose of higher education: the role of Ubuntu-Currere in re-imagining teaching and learning in South African higher education

ABSTRACT

The 2015–2016 South African higher education students’ movement proved historical for our country in bringing to our dinner tables: issues of higher education transformation and decolonisation; institutional culture(s); curriculum reform; the need to foreground and make inclusive assessment in education; the coloniality in our knowledge production, and more. Influenced by the emergence of the student movements and the critique they have brought to South African higher education, we bring to the fore the often silent critical reflections on the purposes of higher education in general, and in South Africa especially, as they relate to teaching and learning. We propose that the purposes of higher education in relation to teaching and learning ought to respond to (1) context, (2) democratic difference, and (3) cosmopolitan perspectives. We argue that discourses, phases and logics about South African higher education have tended to disregard and, at times, blur the context and differences as well as cosmopolitan perspectives. Using the notion of Ubuntu-Currere, we re-imagine how teaching and learning could respond to context, difference and cosmopolitanism with examples from the South African higher education experience.     

Confirmation bias in structural equation modeling

In this article, a theoretical and philosophical revision of the concept of fit in structural equation modeling and its relation to a confirmation bias is developed. The neutral character of the fit indexes regarding this issue is argued, yielding the conclusion that the creation of new indexes is not a viable protection against confirmation bias. This protection relies on the model modification strategy and the behavior of scientists, rather than on mathematical or computational statistics. The differentiation between two sets of overidentifying constraints and two dimensions for nested models is introduced, leading to a general model‐modification strategy based on the framework of Popper's view of science.
