The purpose of this study was to investigate the effects of using an internal versus external focus of attention during resistance training on muscular adaptations. Thirty untrained college-aged men were randomly assigned to an internal focus group (INTERNAL) that focused on contracting the target muscle during training (n?=?15) or an external focus group (EXTERNAL) that focused on the outcome of the lift (n?=?15). Training for both routines consisted of 3 weekly sessions performed on non-consecutive days for 8 weeks. Subjects performed 4 sets of 8–12 repetitions per exercise. Changes in strength were assessed by six repetition maximum in the biceps curl and isometric maximal voluntary contraction in knee extension and elbow flexion. Changes in muscle thickness for the elbow flexors and quadriceps were assessed by ultrasound. Results show significantly greater increases in elbow flexor thickness in INTERNAL versus EXTERNAL (12.4% vs. 6.9%, respectively); similar changes were noted in quadriceps thickness. Isometric elbow flexion strength was greater for INTERNAL while isometric knee extension strength was greater for EXTERNAL, although neither reached statistical significance. The findings lend support to the use of a mind–muscle connection to enhance muscle hypertrophy.  相似文献

Dyslipidaemia is a major CVD risk factor in the general population. Current evidence suggests that lipid metabolism is altered in RA due to inflammation, and that use of anti-inflammatory therapy may reverse some of these changes. The objective of our study is to compare the effect of treatment with DMARD on lipid fractions after 6 months of therapy. Forty patients who met the American College of Rheumatology, ACR/EULAR criteria for rheumatoid arthritis, with disease duration of less than 1 year and no prior treatment were included in the study. Thirty healthy volunteers were included as controls. The mean DAS-28 at disease onset was 5.15 ± 1.3. Early Rheumatoid Arthritis (ERA) patients exhibited higher serum levels of total cholesterol (TC) and lowdensity lipoprotein cholesterol (LDL-C) and lower serum high-density lipoprotein cholesterol (HDL-C) levels compared to controls. As a consequence, the atherogenic index of plasma [log (TG/HDL-C)], the atherogenic indices: TC/HDL-C as well as LDLC/HDL-C was significantly higher in ERA patients compared to controls. After 6 months of treatment, there was significant reduction of the DAS 28, HDL-C and Apo A-I improved and Lp(a) decreased significantly. All lipid ratios improved, a phenomenon primarily due to the increase in serum HDL-C levels. These changes were inversely correlated with CRP and ESR. In conclusion, ERA patients are characterized by an atherogenic lipid profile, which improves with DMARD therapy.  相似文献   

The school psychologist as a facilitator of a community-wide project to enhance positive learning climate in elementary schools     

Rachel Hertz-Lazarowitz  Moshe Od-Cohen 《Psychology in the schools》1992,29(4):348-358

This study describes a community-wide experimental change program that was initiated by a school psychologist who served as a system facilitator and change agent. The program strived to improve social climate in the classroom, and was executed in the fourth-, fifth-, and sixth-grade classrooms of an entire school system in northern Israel. This paper describes the program's design and rationale as well as its activities. Thirty-three classrooms participated, all of which were assigned randomly into three treatments: two experimental programs working on topics in classroom life, one in small-group settings and the other in whole-class settings, and one control (no program). Classroom climate was measured twice (pre-and posttest) during the school year by answering a modified Hebrew version of the Walberg and Anderson questionnaire developed by Hertz-Lazarowitz and Sharan (1979). Results indicated that increase in positive social climate control occurred in the experimental small-group program in all grade levels. The whole-class treatment showed improvement in higher grades, whereas the no-program control classrooms showed a significant decrease in classroom climate during the year. Three main factors were explained as contributing to the impact of the program on positive social climate. From an organizational perspective, (a) the participation and collegial support of teachers within the school with (b) the active leadership of the school psychologist helped improve social climate. Lastly, (c) the children's responses revealed the importance of experiencing cognitively and affectively the content of the program. This program, with certain modifications, became a consistent part of the school curricula.  相似文献   

Exploring alternative assessments for signing deaf candidates     

Rachel O'Neill  Audrey Cameron  Eileen Burns  Gary Quinn 《Psychology in the schools》2020,57(3):344-361

Attitudes to sign languages or language policies are often not overtly discussed or recorded but they influence deaf young people's educational opportunities and outcomes. Two qualitative studies from Scotland investigate the provision of British Sign Language as accommodation in public examinations. The first explores the views of deaf pupils and staff about the official system for face-to-face interpretation of exam papers. The second investigates a centrally translated digital paper with embedded video questions. Discussion focuses on contrasts between the USA and UK approaches to accommodations, raising issues of standardized technical terms in signed languages, the right to respond in sign, and candidate choice.  相似文献   

Breaking down buy-in: Can lessons from social psychology increase teacher use of proactive behavior management?     

Rachel E. Robertson 《Psychology in the schools》2020,57(11):1771-1786

Disruptive student behavior poses significant challenges for teachers and is associated with negative student outcomes. Research shows that teacher use of empirically-based proactive behavior management (PBM) can improve student outcomes; however, research also indicates that teacher use of PBM is low. One prominent factor in teacher use of PBM is “buy-in,” or personal interest, agreement, and investment in the implementation of a practice. When teachers buy in to an intervention, they may be more likely to implement and maintain the intervention with fidelity. Yet, there is little empirically-based understanding of buy-in or strategies known to increase the buy-in of school staff. The purpose of this paper is to describe research from social psychology that may be useful in developing a theoretical framework for buy-in, as well as approaches to increasing teacher buy-in and use of PBM. Implications for incorporating strategies from social psychology into teacher professional development to increase buy-in and use of PBM are discussed.  相似文献   

School psychologist know thyself: Creativity and alonetime for adaptive professional coping     

Steven Hoff  Ester S. Buchholz 《Psychology in the schools》1996,33(4):309-317

School psychologists' need for coping strategies to deal with increasing job stress is widely acknowledged. Interventions, however, fail to adequately consider inner emotional and spiritual experiences. We believe that without exploring these dimensions of experience we are neglecting and ignoring the fastest route to improved mental health. We focus specifically on creativity and aloneness, viewing these basic human phenomena as promising avenues for exploration. Creativity is viewed as an innate quality that can be accessed via a person's opportunity to experience states of reflective, calm solitude. Aloneness, conceptualized here as “alonetime,” is considered a critical developmental need that originates in infancy and persists throughout the human life cycle (Buchholz & Chinlund, 1994). We suggest creativity and alonetime are presently untapped inborn resources representing flexible and viable coping tools with important potential implications for mental health. In this model lack of creativity and alonetime provide warning to the school psychologist, who upon sensing danger is able to implement required interventions. Even though the school setting seems an unlikely place we suggest the individual as well as the system make alonetime a top priority, leading to less stressed, more “self-actualized” practitioners. © 1996 John Wiley & Sons, Inc.  相似文献   

‘Somewhere over the rainbow’: global projections/local allusions in Tears of the Black Tiger/Fa thalai jone     

Rachel Harrison 《Inter-Asia Cultural Studies》2013,14(2):194-210

Abstract

When director Wisit Sasanatieng’s retro cowboy flick Fa thalai jone (2000 Wisit, Sasanatieng. 2000. Tears of the Black Tiger (Fa thalai jone)  [Google Scholar]) became the first Thai film to be screened at the Cannes Film Festival in May 2001, under the English‐language title Tears of the Black Tiger, Thai cinema seemed to have truly ‘gone international’. This paper examines the striking disparity, however, in the reception of the film by local and global audiences, to the extent that Fa thalai jone and Tears of the Black Tiger might arguably be understood as two discrete and divergent cinematic texts at the level of viewer signification. For Western critics, ‘Tears…’ is unquestionably a piece of postmodern filmmaking, awash with surface aesthetic appeal, intertextual richness and an apparently unrelenting obsession with style that is seemingly devoid of an original reference point. Fa thalai jone, by contrast connotes distinct meanings for Thai audiences, who are more fully attuned to the original references the film pursues and able to read the aesthetic appeal it has to offer in a framework beyond that of the dominant ‘force field’ of interpretation that postmodernism has come to be in the West. Instead Fa thalai jone offers a homage to Thailand’s cinematic past, posing as a ‘genuine Thai film’ (phaphayon thai thae) and comprehended in terms of an alternative dominant force field of meaning, that of traditionalism and reverence for the past. This paper examines the ways in which Tears of the Black Tiger/Fa thalai jone straddles two alternative interpretive positions in an accomplished move on the part of the director to pursue the globally focused aspirations of modern Thai cinema while remaining idiosyncratically faithful to local sensibilities.  相似文献

In this article the authors discuss how the perspectives of Paulo Freire were instructive in addressing the challenges of HIV-AIDS education in Guatemalan Maya immigrant communities with minimal formal education and literacy. The forging of a community-based, collaborative, educational program offers several implications for effective teaching and learning among marginalized communities.  相似文献   

Correlation of fluorescence spectra with chemical structure of some naphthalene derivatives     

A.J. Allen  Rachel Franklin  Ellice McDonald 《Journal of The Franklin Institute》1933,215(6):705-722

A definite relation is shown to exist between the chemical constitution of certain naphthalene derivatives and their fluorescence and absorption behavior. The naphthalene, naphthylamine and naphthol compounds vary in intensity and region in which they fluorescence. When a radical is changed from an α to a β position, a shift in wave-length of the maximum intensity occurs. From the shape of the densitometer tracings a difference between an acid and its salt is readily discernible.The quality of fluorescence is roughly the same whether the source of excitation be ultraviolet light, X-rays or cathode rays. It is also independent of the concentration and, in the case of the specimens studied, independent of small amounts of impurities.  相似文献
