A comparison of well-peer mentored and non-peer mentored athletes’ perceptions of satisfaction     

Matt D. Hoffmann  Todd M. Loughead 《Journal of sports sciences》2016,34(5):450-458

The purpose of the present study was to compare well-peer mentored and non-peer mentored athletes’ perceptions of satisfaction. A total of 444 intercollegiate athletes (272 well-peer mentored and 172 non-peer mentored) from a variety of sport teams participated in the study. Athletes from both well-peer mentored and non-peer mentored groups reported their satisfaction levels using the Athlete Satisfaction Questionnaire. The results of a MANOVA and follow-up post hoc ANOVAs showed that well-peer mentored athletes were significantly more satisfied than their non-peer mentored counterparts in terms of individual performance, personal dedication, team task contribution, team social contribution, team integration, ethics, ability utilisation and training and instruction. Overall, the findings suggest that athletes who are well-peer mentored by a teammate perceive higher satisfaction levels with various aspects of their athletic experience than athletes who are not peer mentored by a teammate. Given these positive findings, practitioners (i.e., coaches, sport psychology consultants) should inform athletes on the benefits of peer-to-peer mentoring. The practical implications of the results and strategies to promote peer athlete mentoring relationships in sport are highlighted.  相似文献

Motivbasierte Passung von Sportprogrammen     

Ass. Prof. Dr. Gorden Sudeck  Achim Conzelmann 《Sportwissenschaft》2011,41(3):175-189

Regarding the phenomenon of mood improvements through physical exercise, secondary analyses indicate that improvements can hardly be generalised. Rather, personal and situational factors need to be taken into consideration in order to define the effects in a more precise manner. This contribution investigates to what extent explicit motives and goals of individuals in middle adulthood can be considered as personal moderators of mood changes. Five exercise programmes were developed in a quasi-experimental design and were conducted over a 3-month intervention period. These programmes were based on the “motive-based types of sportsperson” (Sudeck, Lehnert & Conzelmann, 2011), which define groups of individuals with similar motive and goal profiles. One hundred and thirty-three individuals participated in either a programme tailor-made to their motive and goal profile or in a non-tailored programme. The influence of this motive-based tailoring was investigated based on the mood dimensions of valence, calmness and positive activation using handheld PCs during and after exercise sessions. Results indicate a moderating influence of explicit motives and goals. This moderation was however not a general one but rather depended on the exercise programmes’ specific goals and content as well as on individuals’ goals regarding recreation. These findings point towards a systematic consideration of explicit motives and goals in the planning of health and leisure sport programmes.  相似文献

Defining information—II: A quantitative evaluation of the information content of documents     

Eliahu Hoffmann 《Information processing & management》1982,18(3):133-139

For the quantitative determination of the information content (IC) of documents, two requisite parameters were defined. First, the information unit (IU) as the smallest unit consistent with our previous definition of information, and second, its connectivity (C), namely, the extent to which it is connected with other information units in the document. The total quantity of information contained therein is then a function of the number of information units, as well as their connectivities.  相似文献

Advisory work as assistance in problem-solving — Problem-solving models as basic concepts for advisory work     

Volker Hoffmann  Angelika Thomas 《The Journal of Agricultural Education and Extension》2013,19(2):61-73

Abstract

This article summarises some basic concepts of advisory work, incorporated into novel forms of extension over the past half century at Hohenheim University, Stuttgart, Germany. It emphasis a certain understanding of advisory work: as support through “mental help” in structuring and restructuring by informing, motivating and enabling. Through exercises given in the article one can get the idea that problem situations are determined by one's own lack of insight and difficulties in breaking through the limitations of perceptions. The concept presented here in “stages of systematic problem-solving” starts with the perception of a problem by the client. The further critical steps are described within this process from perception of a problem towards solutions and evaluation of results. Two other models that are useful in thinking about problem-solving are also presented. Advisors should value them and be able to make use of them in a flexible way.  相似文献

What Is a “Semiotic Perspective”, and What Could It Be? Some Comments on the Contributions to This Special Issue     

Michael H. G. Hoffmann 《Educational Studies in Mathematics》2006,61(1-2):279-291

This comment attempts to identify different “semiotic perspectives” proposed by the authors of this special issue according to the problems they discuss. These problems can be distinguished as problems concerning the representation of mathematical knowledge, the definition and objectivity of meaning, epistemological questions of learning and activity in mathematics, and the social dimension of sign processes. The contributions are discussed so as to make visible further research perspectives with regard to “semiotics in mathematics education”.  相似文献
