This study investigates the American presence and influences in the physical education press to understand the way in which that presence influenced and contributed to the production of a sports culture in the first half of the twentieth century. As historical sources, the study uses periodicals in the field that were published in the period 1932–1950. As a theoretical frame of reference, it uses the repertoire of the New Cultural History in terms of strategy, tactics and devices. It is written in a narrative way, following Ginzburg's style, presenting data and contextualizing them with the historic scene. Clues enabled us to infer that the American presence, which was catalysed by the Brazilian Young Men's Christian Association (YMCA), sought to shape a sports culture from physical education and society. This effort reflected the yearning of Brazilian intellectuals for modernisation and an attempt at cultural colonisation by the government of the USA.  相似文献   

Development of creativity: The influence of varying levels of implementation of the DISCOVER curriculum model, a non-traditional pedagogical approach     

C. June Maker  Sonmi Jo  Omar M. Muammar 《Learning and individual differences》2008,18(4):402

Development of creativity is influenced by multiple factors, including the environment, developmental changes, and measurement tools. In this study, we investigated the relationship between creativity development and implementation of the Discovering Intellectual Strengths and Capabilities while Observing Varied Ethnic Responses (DISCOVER) curriculum model. Using the Test of Creative Thinking–Drawing Production (TCT-DP), 1986 culturally diverse, low-income students, K through 6, in four elementary schools in the U.S. were assessed for three consecutive years. The creativity of all children increased from grades K to 6, but children in classrooms of low implementers demonstrated a dip and some “pauses.” Differences in scores of children in middle/high and low implementers' classrooms were significant. The implication is that creativity development is supported through active learning, student choice, access to varied materials, exploration, self-evaluation, problem finding, and problem solving. Additional analyses need to be conducted to uncover cultural and linguistic influences in these four schools.  相似文献   

An Architecture for Case-based Learning     

By Laurent Cifuentes  Rene Mercer  Omar Alverez  and Riccardo Bettati 《TechTrends》2010,54(6):44-50

We report on the design, development, implementation, and evaluation of a case-based instructional environment designed for learning network engineering skills for cybersecurity. We describe the societal problem addressed, the theory-based solution, and the preliminary testing and evaluation of that solution. We identify an architecture for scaffolding case-based learning for problem-solving to inform design of case-based learning environments.  相似文献   

The role of educational information systems for survival in information society and the case of Pakistan     

Farzana Shafique  Khalid Mahmood 《International Information and Library Review》2010,42(3):164-173

The study reviews the important role of information systems and their impact on educational planning and development. It also attempts to identify gaps in the provision of information needed by educational administrators who are key planners of education enterprise in Pakistan. It intended to determine their views about the development, objectives and needed services of a user centered information system for educational administrators. To achieve these objectives, a literature review, questionnaire survey and interviews were conducted. Thus, the educational administrators (i.e., registrars/deans/chairpersons in universities and principals of schools and colleges) were identified as the target population for the survey and were selected through cluster sampling. The respondents were from the Punjab province and Islamabad Capital Territory. In total, 297 (99%) responses were received and analyzed quantitatively. Interviews of purposively selected educational administrators were also conducted for a more in-depth understanding of respondents’ points of view. This triangulation of qualitative and quantitative methods helped in understanding the phenomena under study. Recommendations and conclusions are also drawn in the light of findings of the study. The study is the first one of its type that tried to probe the gaps in the process of accurate/valid information supply to educational administrators and planners. This gap is causing serious challenges for education in Pakistan.  相似文献

A remotely operated drug delivery system with an electrolytic pump and a thermo-responsive valve     

Ying Yi  Amir Zaher  Omar Yassine  Jurgen Kosel  Ian G. Foulds 《Biomicrofluidics》2015,9(5)

Implantable drug delivery devices are becoming attractive due to their abilities of targeted and controlled dose release. Currently, two important issues are functional lifetime and non-controlled drug diffusion. In this work, we present a drug delivery device combining an electrolytic pump and a thermo-responsive valve, which are both remotely controlled by an electromagnetic field (40.5 mT and 450 kHz). Our proposed device exhibits a novel operation mechanism for long-term therapeutic treatments using a solid drug in reservoir approach. Our device also prevents undesired drug liquid diffusions. When the electromagnetic field is on, the electrolysis-induced bubble drives the drug liquid towards the Poly (N-Isopropylacrylamide) (PNIPAM) valve that consists of PNIPAM and iron micro-particles. The heat generated by the iron micro-particles causes the PNIPAM to shrink, resulting in an open valve. When the electromagnetic field is turned off, the PNIPAM starts to swell. In the meantime, the bubbles are catalytically recombined into water, reducing the pressure inside the pumping chamber, which leads to the refilling of the fresh liquid from outside the device. A catalytic reformer is included, allowing more liquid refilling during the limited valve''s closing time. The amount of body liquid that refills the drug reservoir can further dissolve the solid drug, forming a reproducible drug solution for the next dose. By repeatedly turning on and off the electromagnetic field, the drug dose can be cyclically released, and the exit port of the device is effectively controlled.  相似文献   

Effects of neuromuscular fatigue on perceptual-cognitive skills between genders in the contribution to the knee joint loading during side-stepping tasks     

Abdul Jabbar Khalid  Sujae Ian Harris  Loke Michael  Hamill Joseph  Xingda Qu 《Journal of sports sciences》2015,33(13):1322-1331

This study investigated whether neuromuscular fatigue affects the neuromuscular control of an athlete within a sports context setting and whether these effects were more pronounced in the females. Lower limb joint kinetics of 6 male and 6 female inter-varsity soccer players performing side-stepping tasks in non-fatigue versus fatigue and anticipated versus unanticipated conditions were quantified using 10 Motion Analysis Corporation cameras and a Kistler^? force platform. The Yo-Yo intermittent recovery Level 1 fatigue protocol was employed. Stance foot initial contact and peak forces, and peak joint knee moments of the lower limb were submitted to a 3-way mixed-model repeated measure ANOVA. The results suggested that males tend to elicit significantly higher knee joint loadings when fatigued. In addition, males elicited significantly higher peak proximal tibia anterior/posterior shear force, vertical ground reaction force at initial contact and peak internal rotational moments than females. These findings suggested that males were at greater overall injury risk than females, especially in the sagittal plane. Neuromuscular control-based training programmes/interventions that are designed to reduce the risk of the non-contact ACL injury need to be customised for the different genders.  相似文献   

A cross-cultural analysis of educational leadership for social justice in Israel and Turkey: meanings,actions and contexts     

Khalid Arar  Kadir Beycioglu  Izhar Oplatka 《Compare》2017,47(2):192-206

The research compares principals in Israel (Jewish and Arab) and Turkey and how they perceive and practice their role in promoting social justice (SJ) in their schools in order to bridge socioeconomic and pedagogic gaps. It poses three questions: (1) How do Turkish and Israeli SJ leaders make sense of SJ? (2) What do SJ leaders do in both countries similarly and differently? (3) What factors facilitate or hinder the work of SJ in both countries? The qualitative study employed in-depth semi-structured interviews to collect the narratives of 11 school principals in Turkey and Israel. A comparative, holistic analysis was employed to identify the principals’ perceptions and daily practice of SJ in their schools. The principals reported different sociocultural, national and personal trajectories that shaped their perceptions of SJ, and described strategies used to promote SJ in their daily scholastic policies, processes and practices that meet the school stakeholders’ backgrounds and needs.  相似文献
