MYTHPERCEPTIONS OF HEARING LOSS,HEARING AIDS,AND AGING     

Karen Patterson  Jess Dancer  Dixie Clark 《Educational gerontology》2013,39(3):289-296

Myths are ill‐founded beliefs held uncritically by persons or groups about other persons or groups. Such myths hinder the communication process and lead to negative feelings or attitudes toward older persons with hearing loss. Hudson, Dancer, Patterson, Reynolds, and Tillery (1990) highlighted five common myths of hearing loss and aging. This article explores whether older persons themselves accept these and other myths presented by the DanPat, a 30‐item questionnaire with “Agree‐Disagree” statements such as the following: “Hearing Aids are Best Left to younger Persons Who Can Learn to Use Them,” or “Persons with Hearing Loss are Paranoid and Suspicious.”

Twenty older persons attending a Senior Companions and Foster Grandparents Health Fair filled out the DanPat with the following results to the 30 statements: informed about 14 of the statements; misinformed about 2 statements; and didn ‘t know the correct answer to 14 statements. Of the five prevalent myths presented by Hudson et al., this group of older adults still believes only one, that persons with hearing loss are excellent lipreaders. They don't know what to believe about two others, and they have discarded the remaining two. This article highlights the DanPat and provides correct answers to the questionnaire.  相似文献   

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

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   

Recovery of pulmonary diffusing capacity after maximal exercise     

Jess Rasmussen  Birgitte Hanel  Kari Saunamaki  Niels H. Secher 《Journal of sports sciences》2013,31(6):525-531

Abstract

Pulmonary diffusing capacity (Dl_co), together with spirometric variables, arterial oxygen tension (paO₂) and cardiac output were determined before and at intervals after maximal arm cranking, treadmill running and erogmeter rowing. Independent of the type of exercise, Dl_co increased immediately post‐exercise from a median 13.6 (range 7.3–16.3) to 15.1 (9.3–19.6) mmol min^‐1 kPa^‐1 (P <0.01). However, it decreased to 11.6 (6.9–15.5) mmol min^‐1 kPa^‐1 (P <0.01) after 24 h with cardiac output and paO₂ at resting values, and Dl_co normalized after 20 h. Thoracic electrical impedance at 2.5 and 100 kHz increased slightly post‐exercise, indicating a decrease in thoracic fluid balance, and there were no echocardiographic signs of left ventricular failure at the time of the decrease in Dl_co. Also, active muscle (limb) circumference and volume, and an increase in haematocrit from 43.8 (38.0–47.0) to 47.1 (42.7–49.8) (P <0.01), had normalized at the time of the decrease in Dl_co. Vital capacity, forced vital capacity, forced expiratory volume in 1 s, peak and peak mid‐expiratory flows did not change. However, total lung capacity increased from 6.8 (5.0–7.6) to 7.0 (5.1–7.8) litres (P <0.05) immediately after exercise and remained elevated at 6.9 (5.1–8.7) litres (P <0.05) when a decrease in Dl_co was noted. The results demonstrate that independent of the type of maximal exercise, an approximate 15% reduction in Dl_co takes place 2–3 h post‐exercise, which normalizes during the following day of recovery.  相似文献
