Treadmill Adaptation and Verification of Self-Selected Walking Speed

Abstract

Eighty-two male college students were divided into three equal-size groups for the purpose of testing the transfer effects between motor skills judged similar in perceptual components but different in motor components.

Criterion measures of gross movement ability and static balance were analyzed and practice tasks similar to these criterion measures in perceptual components but different in motor components were developed. All subjects were pretested on the criterion measures, after which groups 1 and 2 practiced 3 min. per day for 28 days on the practice tasks while group 3 performed unrelated isometric exercises. On the post-test, the experimental groups were found to be significantly superior to the control group on gross movement accuracy and static balance. It was implied that the transfer resulted from the similarity in perceptual components of the two motor skills, and that perceptual abilities were subject to improvement through practice.     

Meeting the challenge of HIV and AIDS in the classroom

Contemporary early childhood teachers are facing new challenges as children who test HIV positive or who have AIDS enter the classroom. Providing appropriate health care and educational programs for these children is a major concern of teachers. This article presents a brief discussion of guidelines and issues that might be addressed in an in-service for teachers in general education to prepare them for a student with HIV or AIDS in their classrooms.     

酸碱滴定法测定蛋壳中钙镁总量的改进

对酸碱滴定法测定蛋壳中钙镁总含量进行了改进,借助超声加快试样与盐酸的反应,缩短测定时间;以碳酸钙基准物质和比较滴定确定盐酸、氢氧化钠溶液的准确浓度,使标定、测定条件相近,减小测定误差。实验结果表明,用改进的酸碱滴定法测定实际样品的钙镁总量,操作简便、快速,结果令人满意。     

基于交际适应理论的法官调解话语说服性研究

在法院调解过程中,法官能否通过有效的话语说服当事人改变态度、达成协议将直接影响调解的效果。基于Giles等人提出的交际适应理论,提出法官可通过近似策略、可理解策略、语篇管理策略与人际控制策略传递说服意图,促进信息顺畅、有效交换,增强调解话语的说服性。语料分析表明,调解中多种交际适应策略通常综合使用、相互影响,其效果受动态变化的说服语境影响,过度适应或适应不足都将影响其话语的说服性,影响说服目标的实现。     

Accommodating Employees with Disabilities: Perceptions of Irish Academic Library Managers

This research study investigated the views and practice of third level academic library managers in the Republic of Ireland regarding reasonable accommodation of employees with disabilities (as defined in the Irish Employment Equality Act 1998 as amended by the Equality Act 2004 Equality Act. 2010. 2010 Chapter 15. 8 Web. Apr. 2010 <http://www.equalities.gov.uk/equality_act_2010.aspx> [Google Scholar]).

A mixed methods study (sample of 163 library managers) employed both an online survey (response rate 108/163) and follow-up telephone interviews (23% of respondents). Questions were based on a literature review.

Library managers were aware of a legal duty to accommodate. A majority of library managers subscribed to the social model of disability rather than the medical model. They were less aware of the needs of employees with less visible disabilities. A small majority of library managers reported the presence of an accommodation procedure at their college. A large majority of library managers would not spend more than 0–10% of the library budget on accommodation—in practice, this should be sufficient. A small majority believe that a legal obligation to accommodate is necessary. A majority would adopt a graduated approach (informal to formal) in relation to discriminatory conduct.

On the whole, the legislation was working in practice. However, further disability awareness training of staff was required, and further research should examine the views of library staff with disabilities.     

The relationship between perceived instructor communicator style,argumentativeness, and verbal aggressiveness

The purpose of this study was to examine the interrelationships among perceived instructor communicator style, perceived instructor trait argumentativeness, and perceived instructor trait verbal aggressiveness in the college classroom. Participants were 236 undergraduate students enrolled in a variety of communication courses at a large Eastern university. Results indicated that (a) perceived instructor trait argumentativeness was positively related to the perceived instructor communicator style attributes of impression leaving, contentious, open, dramatic, dominant, precise, relaxed, attentive, and animated; (b) perceived instructor trait verbal aggressiveness was positively related to the perceived instructor communicator style attributes of contentious and precise, and negatively related to the perceived communicator style attributes of impression leaving, relaxed, friendly, attentive, and animated; and (c) perceived instructor use of verbally aggressive messages was related in some way to the perceived instructor communicator style attributes of contentious, impression leaving, friendly, attentive, animated, relaxed, dramatic, and precise.

大学生完美主义、人际容纳与安全感的关系研究

为探究完美主义与人际容纳对大学生安全感的影响,以720名大学生为测试对象,采用大学生完美主义量表、大学生人际容纳量表和安全感量表进行问卷调查.结果表明,大学生完美主义与人际容纳呈显著正相关,与安全感呈显著负相关;人际容纳与安全感呈显著正相关.经回归分析发现,完美主义和人际容纳对安全感具有显著预测作用,完美主义不仅直接影...     

决定无机酸强度的主要因素

无机酸可以分为氢酸和含氧酸两大类,当前在无机化学教学中,对决定无机酸强度的主要因素存在着许多不同的片面看法,其中有不少观点是自相矛盾的,这就给教学造成许多混乱。如果运用酸碱质子理论,根据酸根的质子亲合势的观点,不仅能够很好地阐明氢酸强度的变化规律,而且也能够完满地阐明含氧酸强度的变化规律,所以决定无机酸强度的主要因素是取决于无机酸酸根的质子亲合势的大小。     

Communicated Stereotypes,Attitudes, and Intended Accommodation of Appalachians

ABSTRACT

The study illuminates intergroup cognitions and intended communication towards Appalachians. American MTurk workers’ (N = 252) open-ended responses illuminated stereotype content of “backwards,” “uneducated,” “poor,” “mountain dwelling,” “self-reliant,” “kind,” and “prejudiced,” corroborating non-Appalachians’ closed-ended responses that Appalachians are deemed moderately competent and warm. The previous contact with an Appalachian yielded no significant differences in “attitudes towards Appalachians” scores. Intended (non)accommodations towards Appalachians commonly included “no adjustments,” with a variant array of overaccommodations (e.g. talking slower) and avoidance that either invoked or enforced stereotypes. Results may inform future testing and enhancement of intergroup and interpersonal communication with and about Appalachians.
