The purpose of the present study was to determine the effects of 10-in [0.25-m] versus 16-in [0.41-m] wheelchair handrims on cardiorespiratory and psychophysiological exercise responses during wheelchair propulsion at selected velocities. Fifteen male paraplegics (27.0 +/- 5.5 yrs) performed three discontinuous exercise tests (ACE = arm crank ergometer; WERG = wheelchair roller ergometer) and two 1600-m performance-based track trials (TRACK) under simulated race conditions. There were no significant differences in HR, VO2, VE, HLa, or category-ratio ratings of perceived exertion (RPE) using different handrims during wheelchair propulsion at 4 km.h-1. In contrast, at 8 km.h-1 subjects demonstrated a 13% lower steady state VO2 (p less than .05) using the 10-in handrims, coincident with a 23% lower VE. Steady state HR during WERG at 8 km.h-1 using the 10-in (124.4 +/- 3.9 b.min-1) or 16-in (130.6 +/- 4.6 b.min-1) handrims were not significantly different. There were also no significant differences between ACE or WERG conditions during maximal effort for VO2 or VE. However, HRpeak during ACE was 7% higher than HRpeak during WERG16 (183 +/- 15 b.min-1 vs. 171 +/- 12 b.min-1, p less than .05), and whole blood HLa during ACE was also significantly higher (by 2.3-2.5 mmol; p less than .05) compared to WERG. There were no significant differences for HR, performance time, or RPE between trials using different handrim diameters during the 1600-m event.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

How to deal with emotional abuse and neglect: further development of a conceptual framework (FRAMEA)
Glaser D 《Child abuse & neglect》2011,35(10):866-875
Objective
To develop further the understanding of emotional abuse and neglect.Methods
Building on previous work, this paper describes the further development of a conceptual framework for the recognition and management of emotional abuse and neglect. Training in this framework is currently being evaluated. The paper also briefly reviews more recent work on aspects of the definition, harm caused by emotional abuse and neglect and threshold.Results
The paper arrives at a working definition as ‘persistent, non-physical, harmful interactions with the child by the caregiver, which include both commission and omission.’ There are many forms of harmful caregiver-child interactions, which can be placed in five categories, each category reflecting the fulfillment of one of the child's basic psycho-social needs and requiring a different therapeutic approach for its alleviation. The caregiver-child relationship is embedded within a psycho-social context. It is suggested that greater clarity can be gained about the child and family when information is sorted into the appropriate tiers of concerns: Tier 0 – Social & environmental factors, Tier I – Caregiver risk factors, Tier II – Caregiver-child interactions and Tier III – Child's functioning. It is further suggested that while intervention is required, this is directed towards protection, rather than providing immediate protection of the child. The work takes the form of a time-limited trial of therapeutic work to gauge the capacity of the caregivers to change. This initial work focuses Tiers 0–II. Statutory steps might be required in order to encourage the caregivers to engage. If insufficient progress is achieved, active child protection may be required which might include placing the child in an alternative family. However, some, usually older, children will remain in the emotionally abusive environment and they will require ongoing help and support.Conclusion
While a greater understanding of emotional abuse and neglect is now possible, further evaluation of the utility of this framework is suggested. 相似文献6.

OBJECTIVE: Emotional abuse and neglect is an under-recognized, but actually common, form of child abuse. Professionals in the field continue to find difficulty in recognizing and operationally defining it, and experience uncertainty about proving it legally. There are also questions about intervention and therapy to protect the child in the least detrimental manner. These difficulties have led to delays in recognition and protective intervention. Emotional abuse and neglect are defined as a carer-child relationship that is characterized by patterns of harmful interactions, requiring no physical contact with the child. Motivation to harm the child is not necessary for the definition. Unlike sexual abuse that is a secret activity, these forms of ill treatment are easily observable. The child's development is impaired in all domains of functioning but, not being specific to emotional abuse and neglect, cannot be regarded as diagnostic. METHOD: Research, clinical experience and theoretical considerations have led to a conceptual framework and operational definitions of five categories of harmful interactions between parent and child. This framework is contrasted with the APSAC categories. RESULTS: It is postulated that the different categories of ill treatment respectively require different therapeutic interventions. CONCLUSION: Concerns about the presence of emotional abuse need to trigger an assessment process that includes identifying the nature of the abusive or neglectful interactions and a time-limited trial of specific interventions. The family's response to this process and its outcome will determine the need for statutory involvement, as well as providing a basis for litigation if this is required. 相似文献

In 2009, a think tank called the International Alliance of Leading Education Institutes (IALEI) announced the results of a study entitled Climate Change and Sustainable Development: The Response from Education. Intended for a policy audience, the study offered a glimpse into the status of Education for Sustainable Development (ESD) and an early look at the emergence of Climate Change Education (CCE), in 10 different nations. As with most international reports, the IALEI report provoked many questions, some of which are more broadly relevant to scholarship and practice. This paper introduces a review symposium that addresses three such questions: (1) How coherent is the concept of ESD across national contexts and what conceptual tensions continue to surround ESD and CCE? (2) Can nation-level analyses tell us anything useful about countries where education is not centrally governed? and (3) In light of the evolving relationship between educational research and policy, how should researchers engage with ongoing policy debates? 相似文献
