The aims of this study were to examine the changes in plasma concentrations of inflammatory cytokines induced by training and competition in professional cyclists. We report the serum concentrations of interleukin-6 (IL-6), tumour necrosis factor alpha (TNF-a), tumour necrosis factor receptors I and II (TNFR-I and -II) in a prospective, randomized, double-blind trial involving the administration of AM3 (Inmunoferon), an oral booster immunomodulator, or placebo to 16 professional cyclists (n = 8 in each group) for 65 consecutive days. Serum was collected just before treatment began (baseline), at the end of pre-competition training, before the mountain stage of the competition (60 days), 4 h after finishing this stage (62 days), and 18 h after the fifth and last day of competition (65 days). To determine the normal levels of cytokines and soluble TNF receptors, individual samples from 14 moderately trained healthy controls were studied. After 60 days of training, the serum concentrations of IL-6 did not differ significantly from those at the beginning of the study for either group of cyclists (placebo and AM3). A significant rise was seen in IL-6 concentrations in both the AM3 and placebo groups at 62 days, 4 h after finishing the mountain stage. The increase was significantly greater in the placebo group than in the AM3 group. At 65 days of treatment, 18 h after the fifth and last day of competition, IL-6 concentrations were similar to those recorded at the end of the training, but were significantly higher in the placebo group than in the AM3 group. At the end of training, serum TNFR-I concentrations in both groups of cyclists were significantly lower than at baseline. The concentrations of serum TNFR-I and -II both 4 h after finishing the mountain stage and 18 h after the fifth and last day of competition were significantly higher than those recorded after training in both groups. Professional cycling competition is associated with increases in serum IL-6 and TNFR-I and -II concentrations. Inmunoferon treatment reduced significantly the concentrations of IL-6 but not those of TNFR-I and -II. 相似文献

Amidst global competition in higher education, colleges and universities adopt strategies that mimic and adapt business practices. Branding is now a widespread practice in higher education; multimodal advertisement is a manifestation of emerging branding strategies for universities. While the visibility of brands in higher education has grown substantially in recent years, its empirical study has lagged. This article reports on the findings from a study that employed social semiotic and multimodal analysis to explore text and visual rhetoric as brand construction strategies in publicly displayed university advertisements. After analyzing photographs representing advertising campaigns from 16 different universities displayed in an urban public transportation system, I suggest that universities construct their brand identity through messages that emphasize multiple choices and convenience, but construct success primarily according to corporate standards and values. 相似文献

This article reports on findings from a sociolinguistic qualitative study exploring inter-discursive relations manifested in the approaches and strategies that regional accrediting agencies in the United States utilise when recognising foreign universities. Even as most countries have developed national quality assurance systems and whilst international rankings comparing institutions globally are available, a growing number of universities around the world seek recognition from American regional agencies. By comparing policy statements, manuals, guidelines and other documents, and after interviewing top-level officers at US accrediting agencies, this study makes explicit the assumptions and central discourses associated with US accreditation of non-US institutions of higher education, from the accreditors’ perspective. Following constant comparison and cultural critical discourse analysis, the study reveals concerns about the equivalency of quality, emphasis on capacity building and reluctance toward adapting US standards. An interest in building international partnerships, in order to respond to globalisation, is also identified. 相似文献

In recent years, an increasing number of students with specific learning disabilities (SLDs) have enrolled in universities. The present exploratory study examined the frequency of use and appreciation of universal (open to every student) and specific services (offered to students with SLDs) and their relation to age, academic achievement, satisfaction, self-efficacy, and use of self-regulated learning (SRL) strategies. Participants were 147 Italian university students with SLD diagnoses (42 males; mean age: 22.49, SD = 3.29). Results showed that, overall, the frequency of use and appreciation of specific services were positively related to academic satisfaction, self-efficacy, and SRL strategies. Furthermore, frequency of use of compensatory tools and dispensatory measures was positively associated with academic achievement. These findings suggest that universities play an important role in supporting students with SLDs during their academic years by providing them with useful services and accommodations. 相似文献

ABSTRACTThis paper focuses on university education in prison as a strategic tool for building social inclusion. Using quantitative and qualitative methods, it examines the Italian and Spanish experiences in this area. In Italy and Spain, the idea of punishment having a rehabilitative function has been supported by strong motivation to achieve this ideal. In both countries, the way in which inmates are treated by the prison system was established to oppose prison systems designed by authoritarian regimes. However, the rhetoric of rehabilitation that is now prevalent seems to morally legitimise imprisonment and encourage the emergence of forms of ‘symbolic violence’. For these reasons, focusing attention on higher education in prison takes the form of an analytical and critical exercise that is particularly useful, as it allows the distance between prison and society, and prison and prisoner stereotypes, for example, to be questioned. It also enables the transformative effects that education has on the individual and on the system, beyond any rhetoric of treatment, to be understood. 相似文献

Over the past several decades, the Latino population throughout the USA has demonstrated significant growth and exceeded that of other ethnic minority groups. This influx is particularly evident in the student enrollment of US schools as the number of Latino students has increased by approximately 10 million within the past 10 years. With this dramatic increase, there are a number of critical issues that present significant barriers to a high-quality educational experience for Latino students, specifically overrepresentation of Latinos receiving disciplinary actions and the high number of referrals to special education evaluation for emotional and behavioral disorders. This paper will discuss the impact of the Latino population in US schools, the concern of overrepresentation and biased referrals, and the use of a culturally attuned functional behavioral assessment as a pragmatic solution to better serve this growing population. 相似文献

From the contextual perspective, researchers argue that the relevance and weight of motivational variables of students' functioning vary depending on different dimensions related to individual, cultural or situational characteristics. The first objective of this study examined this contention by comparing self-perceptions of competence, learning goals and judgments of usefulness of school subjects as motivational determinants of high school students' commitment and achievement according to their assignment to their learning abilities. The second objective was to compare how these variables related to academic commitment and achievement according to the type of student and two school subjects. Two-hundred-and-twenty-six high school students from a same school participated sixty-one were learning disabled students, 60 were high achievers and 105 were average students. Findings suggest that the relevance of the motivational variables did not vary much across either the type of student or the school subjects. They also support Bandura's view about the primary role of self-perceptions of competence in students' academic commitment and achievement. 相似文献

The use of networks in education is experiencing world-wide growth. Many schools have taken advantage of the reduction of price in modems, the emergence of electronic bulletin boards and world-wide web pages with educational content, and the availability of software for public participation in networks. Nevertheless, little information is available about the quality and quantity of existing network traffic; information that would allow organizations, network project administrators and supporters, to evaluate its impact, know its usage, evolution and projections. This paper presents some of the traffic monitoring mechanisms presently in use in a Chilean educational network (the Enlaces Project), together with examples of the information collected through these mechanisms. 相似文献

We present the design of a new 3D animation tool for self‐teaching (signing and reading) finger spelling—the first basic component in learning any sign language. We have designed a highly realistic hand with natural animation of the finger motions. Smoothness of motion (in real time) is achieved via programmable blending of animation segments. The hand is utilised by a programme that automatically converts text to finger spelling with controllable playback speed and playback views. The programme can be operated in two modes for two basic applications: learning to read (finger spelling) and learning to sign. For both modes, multi‐sided views are provided. In addition, for the signing mode, a mirror view is provided for the common technique of using a mirror for feedback in practising finger spelling. An additional view revealing the joint structure of the hand allows the signer to practise the subjective view without having to guess the position of the fingers. This is the first example of highly realistic 3D animation that can be used practically to teach a basic aspect of sign language. The method is applicable more generally to sign language, and this finger‐spelling application should be regarded as a first step toward the extension of highly realistic 3D animation to sign language in general. 相似文献
