Emblematic gestures among Hebrew speakers in Israel     

Michaela Safadi  Carol Ann Valentine 《Int J Intercult Relat》1988,12(4)

A field study was conducted in Israel to identify emblematic gestures recognized and used by Hebrew speakers. Studies which have identified the emblematic gestures of particular ethnic or national groups are reviewed and criticized. This study seeks to contribute increased rigor and systematology to the identification of particular groups' emblematic gestures.Twenty-six gestures commonly used in classroom interaction were selected for testing. The instrument used was Schneller's form, “Investigations of Interpersonal Communication in Israel.” Subjects included college students, members of YMCA classes for pensioners, and others. On the instrument, subjects noted their recognition and interpretations of the investigator's encoding intentions, their certainty or interpretation and where they learned each gesture.Whereas previous studies of this nature accepted around 70% interpretive agreement among subjects, this study indicates that at least 90% is a more reliable measure by which to label gestures “emblems.” In addition, correlations were tabulated for the effects of subjects' age, ethnicity, years in Israel, certainty about interpretation, and accuracy of interpretation.The findings of this study were: (a) eight gestures were identified as emblems, and three more gestures identified as possible emblems, (b) slightly negative although insignificant correlations were found between increased age, years in Israel, expressed certainty of interpretation and accuracy of interpretation, and (c) natives and subjects from 20–24 years of age tended to have the highest rates of expressed certainty of interpretation as well as accuracy of interpretation.The findings are compared with those of three other studies of Jews' gesturing and differences between the studies are considered. Recommendations include continuing such studies and comparing the results of related projects in order to form a comprehensive picture of particular groups of people.Limitations are discussed. These include: (a) a less than representative sample, (b) lack of a consistent conversational context, (c) potential for distortion in the decoding process, (d) the lack of a unified gesture labeling system, and (e) the possibility of cultural or researcher bias.  相似文献   

A twin-study of sleep difficulties in school-aged children     

Gregory AM  Rijsdijk FV  Eley TC 《Child development》2006,77(6):1668-1679

This study examines frequency, overlap, and genetic and environmental influences on sleep difficulties, which are understudied in school-aged children. The Sleep Self Report and the Children's Sleep Habits Questionnaire were completed by 300 twin pairs (aged 8 years) and their parents. Child report suggested more frequent sleep problems than parent report (e.g., regular sleep onset delay was reported by 45% of children and 17% of parents). Associations between most of the sleep difficulties were small but significant (e.g., r(s)=.16 for parent report of bedtime resistance and sleep onset delay). Twin correlations based on parent reports suggest greater genetic influence (M=50%) than those based on child self-report (M=18%). Possible rater effects should be considered when evaluating children's sleep problems.  相似文献

The effects of mid-flight whole-body and trunk rotation on landing mechanics: implications for anterior cruciate ligament injuries     

Meghan L. Critchley  Daniel J. Davis  Michaela M. Keener  Jacob S. Layer  Margaret A. Wilson  Qin Zhu 《Sports biomechanics / International Society of Biomechanics in Sports》2020,19(4):421-437

ABSTRACT

The purpose was to quantify the effects of mid-flight whole-body and trunk rotation on knee mechanics in a double-leg landing. Eighteen male and 20 female participants completed a jump-landing-jump task in five conditions: no rotation, testing leg ipsilateral or contralateral (WBRC) to the whole-body rotation direction, and testing leg ipsilateral (TRI) or contralateral to the trunk rotation direction. The WBRC and TRI conditions demonstrated decreased knee flexion and increased knee abduction angles at initial contact (2.6 > Cohen’s dz > 0.3) and increased peak vertical ground reaction forces and knee adduction moments during the 100 ms after landing (1.7 > Cohen’s dz > 0.3). The TRI condition also showed the greatest knee internal rotation angles at initial contact and peak knee abduction and internal rotation angles and peak knee extension moments during the 100 ms after landing (2.0 > Cohen’s dz > 0.5). Whole-body rotation increased contralateral knee loading because of its primary role in decelerating medial-lateral velocities. Trunk rotation resulted in the greatest knee loading for the ipsilateral knee due to weight shifting and mechanical coupling between the trunk and lower extremities. These findings may help understand altered trunk motion in anterior cruciate ligament injuries.  相似文献   

Managing mergers — governancing institutional integration     

Frølich  Nicoline  Trondal  Jarle  Caspersen  Joakim  Reymert  Ingvild 《Tertiary Education and Management》2016,22(3):231-248

Despite striking similarities, the adoption and implementation of policy shifts regarding higher education governance vary considerably across the globe, suggesting a mixed picture of diversification and isomorphism both within and across national higher education systems. By unpacking one particular structural reform process, this paper focuses on mergers as both a governance tool and a governance result in higher education. The paper analyzes the strategic decisions taken by Norwegian higher education institutions during 2014 in the light of a proposed national reform to merge institutions in order to enhance quality in higher education. The empirical basis of the paper consists of analyses of the commissioned self-evaluations of the higher education institutions, and the strategic choices and dilemmas they expressed. The process can be seen as organizational engineering in the sense that it emerges from the self-evaluation process, but is also subject to governancing on the part of the ministry.  相似文献   

Validity of Holland’s theory in adolescence: evidence from a Slovak sample     

Martončik  Marcel  Kačmárová  Monika  Hruščová  Eva  Magáčová Žilková  Ivana  Kravcová  Michaela 《International Journal for Educational and Vocational Guidance》2020,20(3):543-565

The underlying calculus assumption of Holland’s theory was tested in two samples of primary school students (N₁ = 400 and N₂ = 250) with an average age of 13.86 and 14.14 years, respectively. Both exploratory and confirmatory multidimensional scaling and Hubert and Arabie’s randomization test of hypothesized order relations were calculated. The circular spatial arrangement of RIASEC types was not confirmed in either of the two samples. The study discusses possible causes of the inappropriateness of using Holland’s model in an adolescent sample.

Violent Political Contexts and the Emotional Concerns of Township Youth   总被引：1，自引：0，他引：1  

Gill Straker  Michaela Mendelsohn  Fathima Moosa  Pam Tudin 《Child development》1996,67(1):46-54

This article presents the findings of a series of studies that examine the perceptions of black South African youth about township life and the civil conflict and violence it encompasses. The studies were conducted with comparable samples of 58–82 youth at 3 points in South Africa's history, all characterized by high levels of violence but differing in terms of their political contexts. These contexts were overt State-community conflict, covert opposition and political repression, and intracommunity violence. The data revealed that in all 3 contexts youth reported a high exposure to violence, but only when violence occurred in the context of intracommunity conflict was it subjectively construed to be the most problematic. Reasons for this may include the real increase in more extreme forms of violence, including deaths, that occurs in intracommunity violence and the blurring of the distinction between political and criminal violence in this context.  相似文献

To give or not to give: children's and adolescents' sharing and moral negotiations in economic decision situations     

Gummerum M  Keller M  Takezawa M  Mata J 《Child development》2008,79(3):562-576

This study interconnects developmental psychology of fair and moral behavior with economic game theory. One hundred eighty-nine 9- to 17-year-old students shared a sum of money as individuals and groups with another anonymous group (dictator game). Individual allocations did not differ by age but did by gender and were predicted by participants' preferences for fair allocations. Group decision making followed a majority process. Level of moral reasoning did not predict individual offers, but group members with a higher moral reasoning ability were more influential during group negotiations and in influencing group outcomes. The youngest participants justified offers more frequently by referring to simple distribution principles. Older participants employed more complex reasons to justify deviations from allocation principles.  相似文献   

Apprenticeship in England – the continued role of the academic–vocational divide in shaping learner identities     

Michaela Brockmann  Ian Laurie 《Journal of Vocational Education & Training》2016,68(2):229-244

Successive governments have pledged to enhance the quality of apprenticeship in Britain so as to achieve ‘parity of esteem’ with academic study. Yet, at the same time, the discourse of the academic-vocational divide has dominated the academic, policy-maker and practitioner debates. This paper draws on two recent studies designed to explore the learner identities of apprentices on different apprenticeship programmes: motor vehicle maintenance (level 2) and engineering (level 3). Through this work, we are able to explore the role of the academic–vocational divide in identity construction and to challenge assumptions about vocational learners. It will be argued, that, far from being ‘naturally practical’, the young people draw on normative discursive categories in their construction of continuous identities. The findings raise important questions about the UK apprenticeship system as currently conceived, while at the same time drawing attention to the possibility for change.  相似文献
