Dissent and assent contribute to new information and knowledge in that they foster ideas, avert errors and counter misplaced beliefs. Although intended to facilitate progress, innovation and creativity, dissent may be opposed by the closed mind and defensive mindset. Don Lamberton encountered a specific mindset in his own duties to scholarship in economics. Thus, the perspective of dissent is a fitting way to pay homage to his scholarship. However, this paper is also a lament. It gives an interpretation of Antigone from political philosophy which depicts Antigone rocking an ideological boat harboured by the polis. The silencing of Antigone’s voice results in unexpected losses in the oikos. This is the sort of tragedy threatening critical and innovative scholarship in the twenty-first century. 相似文献

This paper presents the bibliometric characteristics of 32 biomedical open access journals published by Academic Journals and International Research Journals – the two Nigerian publishers in Jeffery Beall's list of 23 predatory open access publishers in 2012. Data about the journals and the authors of their articles were collected from the websites of the publishers, Google Scholar and Web of Science. As at December 2012, the journals had together produced a total of 5,601 papers written by 5,599 authors, and received 12,596 citations. Authors from Asia accounted for 56.79% of the publications; those from Africa wrote 28.35% while Europe contributed 7.78%. Authors from Africa accounted for 18.25% of the citations these journals received, and this is about one‐third the number of citations by authors in Asia (54.62%). At country level, India ranks first in the top 10 citer countries, while Nigeria, the host country of the journals, ranked eighth. More in‐depth studies are required to develop further information about the journals such as how much scientific information the journals contain, as well as the science literacy of the authors and the editorial. 相似文献

A major feature of education in the twenty-first century is assessment. Forensic educators should heighten the importance of learning outcomes and utilize assessment efforts to directly measure how forensic programs develop educational foundations for students. This article focuses on the use of tournaments and noncompetitive educational outcomes, such as engagement within academic communities, service-learning, and the promotion of the value of forensics, to connect the educational benefits of the activity to help define the mission of forensics in the twenty-first century. 相似文献

For individuals with strong work identities, the decision to retire can be particularly challenging. For academic physicians, retirement is an important personal decision that also has far-reaching implications for the healthcare system. This is because academic physicians are responsible for producing the research from which key medical decisions are made, for training future healthcare providers, and for providing specialized care for patients. For this study, we conducted focus groups with academic physicians from a large research university in Canada and then performed inductive thematic analyses to examine perceptions and concerns about later life career transitions. This study highlights tensions between professional experiences for the next generation of physicians and individual struggles with personal identity. Findings suggest improvements to institutional programs that support flexible, agentive, and respectful retirement transitions will not only be beneficial but necessary as medical and university systems continue to grapple with issues of balanced recruitment and succession. 相似文献

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (Ncases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions. 相似文献

Studies show that spatial interventions lead to improvements in mathematics. However, outcomes vary based on whether physical manipulatives (embodied action) are used during training. This study compares the effects of embodied and non-embodied spatial interventions on spatial and mathematics outcomes. The study has a randomized, controlled, pre-post, follow-up, training design (N = 182; mean age 8 years; 49% female; 83.5% White). We show that both embodied and non-embodied spatial training approaches improve spatial skills compared to control. However, we conclude that embodied spatial training using physical manipulatives leads to larger, more consistent gains in mathematics and greater depth of spatial processing than non-embodied training. These findings highlight the potential of spatial activities, particularly those that use physical materials, for improving children's mathematics skills. 相似文献

This discussion focuses on how the rise of America's national sporting pastimes, during the period 1880–1920, was inextricably tied to the ambitions and outpourings of American print capitalism and a concomitant congealing of a sense of modern American nationhood. In examining this thematic, we explicate the manner in which American national sporting audiences during the period 1880–1920 were variously constituted through discourses of national and ethnic sporting difference or Otherness. Hence, we examine the popular representation of turn of the century rodeo practices (as narrated through the spectacle of the western showman William Frederick ‘Buffalo Bill’ Cody's Wild West show productions), the position of early-twentieth-century American baseball in relation to other sporting cultures (graphically depicted by Albert Goodwill, or A.G., Spalding's promotional publications, specifically the 1911 America's National Game) and the national and ethnic differences discerned within the global sporting landscape more generally (explicated within the 1919 National Geographic article ‘The Geography of Games’). These performances and representations of ethnic and national sporting Otherness played an important role in re-inscribing and legitimating the (White European American) normative core of American sport culture (as manifest within and through the dominant practices of playing and/or spectating of football, baseball and basketball). 相似文献

This paper advances the ongoing discussion of methods for predicting movie box office revenues with two contributions to the methodology and an out-of-sample test of the model. The first innovation is the development of a two-stage model using publicly available pre-release indicators to predict (1) initial week and (2) subsequent run box office revenues. To incorporate the experience-good nature of movies, the second stage is estimated by incorporating a proxy variable for box office success during the first week relative to predicted first week success. The second contribution is an empirical test of De Vany and Walls’ (J Econ Dyn Control 28:1035–1057, 2004) finding that the distribution of movie revenues has “heavy tails” and follows a non-Gaussian stable distribution with infinite variance. We estimate the two-stage model of a movie’s box office success on all general release movies in 1 year with both the Gaussian and stable distribution with heavy tails and infinite variance and find no evidence for the stable distribution in either stage of the estimation. This two-stage model is validated by comparing all general release movies in 3 future years (out-of-sample data) to the model’s predictions. 相似文献
