Return to play management after concussion in football: recommendations for team physicians

Abstract

A concussion is a rare but potentially serious injury of football players. Thus, an immediate and valid diagnosis, estimate of severity and therapeutic management is required. To summarise the published information on management of concussion with respect to a safe return to play (RTP), a literature search was conducted. Current guidelines on concussion in sports and significant studies on concussion in football were analysed. After concussion, management and RTP decision should remain in the area of clinical judgement on an individualised basis according to the current international guidelines. If a concussion is suspected, the player should not be allowed to RTP the same day. The RTP programme should follow a gradual step-wise procedure. A concussed player should not RTP unless he/she is asymptomatic and the neurological and neuropsychological examinations are normal. Untimely RTP bears an increased risk of sustaining another more severe brain injury and repetitive brain injury of long-term sequelae. In football, the management of concussion should primarily follow the recommendations proposed by the Concussion in Sports Group. Information and education of players and their medical and coaching team help to protect the players’ health. Future studies on concussion should include validated and detailed information on RTP protocols.     

Exploring the Usefulness of Kelly's Personal Construct Theory in Assessing Student Learning in Science Courses

We explore the utility of George Kelly's Personal Construct Theory, specifically his repertory grid technique, to the assessment of student learning in undergraduate science courses. We provide an in-depth review of the assumptions underlying Personal Construct Theory and how these were reflected in the repertory grid technique Kelly developed. We explain how an adapted version of the repertory grid, sharing some yet not all of Kelly's assumptions, was utilised as a research tool in a recent study involving science instructors and their students. We argue that as well as having applicability as an innovative research tool, an adapted version of Kelly's repertory grid is a useful heuristic for university teachers when used as a classroom assessment technique (CAT) and indicate several features it shares with the more widely-known conceptual mapping technique, which has been used in the study of science teaching and learning for many years. We conclude by highlighting several advantages the use of repertory grids has for both students and instructors.     

The (Un)Common Instructor: A New Role for Medical Librarians Beyond Information Literacy

University common reading programs provide a shared experience as students transition into college life and develop critical thinking skills. Typically in such programs, all students in an incoming class read and discuss the same book. Conversely, the University of Florida Honors Program’s (un)common reads facilitates the same skills development through multiple small sections, each focusing on a different book and each with flexible and innovative assignments and activities. Health Science Center librarians have taught in these (un)common reads since the spring semester 2010–2011. This article describes librarian involvement in this program as well as the ensuing benefits for students, librarians, and the university at large.     

Organizational response to decline in the academic marketplace

In the last twenty-five years institutions of higher education and the academic market-place have undergone considerable change. A period of rapid growth and expansion was followed by a period of shrinking resources and decreasing growth. The effects of organizational decline on personnel management and on the formal structure of the academic hierarchy are examined in Israeli universities. The data show that in the non-growth period standards for faculty selection and advancement have not been formally altered, although actual practices have resulted in prolonged time periods between promotions and until tenure is obtained. The most salient change that has taken place is a continuous process of proliferation of the academic hierarchy by addition of new tracks and ranks to the main regular faculty track, and the increasing use of these positions particularly for new hires. This is consistent with other studies which found that organizational complexity may increase under conditions of decline. The effectiveness and functions of this process as an adaptive response to environmental scarcity are discussed.     

Blurred Boundaries or Conflicting Epistemologies

In this article, I discuss how information activists and journalists in Egypt claimed to acquire knowledge about the world, looking particularly at the period of 2012 and 2013, during which the Supreme Council of the Armed Forces and Mohammed Morsi in turn were leading the country. Taking a point of departure in anthropological fieldwork with information activists and journalists in Egypt, I show that information activists and journalists often had very similar practices and goals, which at times made the boundaries very blurry. Yet I argue that there was a significant distinction between the epistemologies of information activists and journalists. Information activists claimed to acquire knowledge about events from being part of them, whereas journalists claimed to acquire knowledge about events from observing them without taking part. Relatedly, information activists and journalists had significantly different relationships with their audiences.     

不同阅读方式下学前儿童在图画书阅读中对文字的关注

分享阅读被认为可以有效提高儿童的文字意识,因为它可以使儿童获得更多与文字接触的机会。为了验证以上观点,本研究以SMI眼动仪为工具,对71名3~6岁幼儿在自主阅读和分享阅读方式下阅读图画书的特点进行考察。结果发现:分享阅读不能提高学前儿童对文字的关注程度,自读方式则可以增加儿童与文字接触的机会;儿童对文字的关注程度随着年龄班的增长而提高,且在小班与中班之间变化最为明显;阅读方式不影响儿童对主人公的关注程度;分享阅读提高了儿童信息加工的速度,且该效应在小班最明显;儿童对图画书中隐藏细节信息的关注程度随着年龄班的增长而降低。     

Paternal Sensitivity and Children’s Cognitive and Socioemotional Outcomes: A Meta-Analytic Review

In a series of meta-analyses, paternal sensitivity was associated with children’s (age range: 7 months–9 years) overall cognitive functioning (N = 3,193; k = 23; r = .19), including language skills (k = 9; r = .21), cognitive ability (k = 9; r = .18), and executive function (k = 8; r = .19). Paternal sensitivity was not associated with children’s overall socioemotional functioning (N = 2,924; k = 24; r = −.03) or internalizing problems, but it was associated with children’s emotion regulation (k = 7; r = .22) and externalizing problems (k = 19; r = −.08). In the broad cognitive functioning, executive function, broad socioemotional functioning, and externalizing problems meta-analyses, child age was a significant moderator.     

Maternal Insightfulness and Resolution of the Diagnosis Are Associated With Secure Attachment in Preschoolers With Autism Spectrum Disorders

In the current study (a) maternal insightfulness into the experience of the child and (b) resolution with respect to the child's diagnosis and their associations with children's security of attachment were examined in a sample of 45 preschoolers (mean age = 49 months) with autism spectrum disorders (ASD). It was hypothesized that mothers who were insightful and resolved would be more likely to have securely attached children than mothers who were neither insightful nor resolved. The findings supported this hypothesis. The implications of insightfulness and resolution for child attachment in the context of ASD are discussed.
