For Better or Worse? System-Justifying Beliefs in Sixth-Grade Predict Trajectories of Self-Esteem and Behavior Across Early Adolescence     

Erin B. Godfrey  Carlos E. Santos  Esther Burson 《Child development》2019,90(1):180-195

Scholars call for more attention to how marginalization influences the development of low-income and racial/ethnic minority youth and emphasize the importance of youth's subjective perceptions of contexts. This study examines how beliefs about the fairness of the American system (system justification) in sixth grade influence trajectories of self-esteem and behavior among 257 early adolescents (average age 11.4) from a diverse, low-income, middle school in an urban southwestern city. System justification was associated with higher self-esteem, less delinquent behavior, and better classroom behavior in sixth grade but worse trajectories of these outcomes from sixth to eighth grade. These findings provide novel evidence that system-justifying beliefs undermine the well-being of marginalized youth and that early adolescence is a critical developmental period for this process.  相似文献   

The fatigue effect of a simulated futsal match protocol on isokinetic knee torque production     

Juliano Dal Pupo  Saray Giovana Dos Santos 《Sports biomechanics / International Society of Biomechanics in Sports》2014,13(4):332-340

The objective of this study was to investigate the effects of a simulated futsal match protocol on isokinetic knee torque production. Twenty-one young futsal players participated in this study and performed a futsal-specific protocol comprising two blocks of 20-minute activities to simulate the match demands. At pre-protocol, half-time, and post-protocol, the concentric and eccentric isokinetic peak torque of the knee flexor and extensor muscles, the angle of peak torque, and the conventional and functional torque ratios were assessed. ANOVA was used to compare the variables (significance level p < 0.05). A decrease of knee flexor and extensor eccentric torque and knee flexor concentric torque was found, in which the pre-protocol levels were higher than those at half-time, with both being larger than those at post-protocol. The knee extensor concentric torque reduced at half-time. The angle of eccentric torque of knee flexors increased, and the conventional and functional torque ratios decreased at post-protocol. In conclusion, the protocol produced a time-dependent reduction of knee flexor and extensor torque in both concentric and eccentric actions. These findings suggested a possible impairment of performance and the emergence of risk factors for hamstring strains during a futsal match.  相似文献

Stiffness,intralimb coordination,and joint modulation during a continuous vertical jump test     

Juliano Dal Pupo  Jonathan Ache Dias  Rodrigo Ghedini Gheller  Daniele Detanico  Saray Giovana Dos Santos 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(3):259-271

This study analysed the modulation of jump performance, vertical stiffness as well as joint and intralimb coordination throughout a 30-s vertical jump test. Twenty male athletes performed the test on a force plate while undergoing kinematic analysis. Jump height, power output, ground contact time, vertical stiffness, maximum knee and hip flexion angles, and coordination by continuous relative phase (CRP) were analysed. Analysis of variance was used to compare variables within deciles, and t-tests were used to compare CRP data between the initial and final jumps. Results showed reduction in jump height, power output, and vertical stiffness, with an increase in contact time found during the test. Maximum knee and hip flexion angles declined, but hip angle decreased earlier (10–20% of the test) than knee angle (90–100%). No changes were observed in CRP for thigh–leg coupling when comparing initial and final jumps, but the trunk–thigh coupling was more in-phase near the end of the test. We conclude that fatigue causes reduction in jump performance, as well as changes in stiffness and joint angles. Furthermore, changes in intralimb coordination appear at the last 10% of the test, suggesting a neuromotor mechanism to counterbalance the loss of muscle strength.  相似文献

Language skills and cognitive processes related to poor reading comprehension performance     

O B Santos 《Journal of learning disabilities》1989,22(2):131-133

Eleven tests were administered to 20 high school readers with learning disabilities (LD) and 20 controls. The objective was to examine the relation between reading comprehension performance and performance on tests of language skills and cognitive processes. As a whole, the performance of the group with LD was significantly below the performance of the controls on all measures. However, the variance on nonverbal tests was greater for the group with LD than for controls; some individuals with learning disabilities performed as well as the controls. Results are discussed in terms of how performance deficits are amenable to remediation by instruction.  相似文献   

The body donation program at the Federal University of Health Sciences of Porto Alegre: A successful experience in Brazil     

Andrea Oxley da Rocha  Diane Alícia Tormes  Natassia Lehmann  Rafael Santos Schwab  Raphael Teixeira Canto 《Anatomical sciences education》2013,6(3):199-204

The use of dissection to study human anatomy is the foundation for educational excellence among future health professionals, as it offers an ideal opportunity to learn the body's morphology in three dimensions while also providing students with a more humanistic education. The shortage of bodies for dissection, combined with the Brazilian population's lack of knowledge concerning the possibility of voluntarily donating their own bodies, led to the creation of the Body Donation Programs for Education and Research in Anatomy at the Federal University of Health Sciences of Porto Alegre (UFCSPA). The program is based on three pillars: Informing the general public about the program, donor registration, and donation itself. Since the creation of the donor program in 2008, there has been an increase in both the number of donations made during donor's lifetime and the number of bodies received by the university. There has also been a shift in relation to the origin of these bodies, as before the creation of the program most bodies were unclaimed cadavers, while today most of the bodies are sourced from voluntary donations. The initial results regarding the public's acceptance of the possibility of making body donations have been encouraging, as shown by the annual growth in donor registrations. Consequently, the quality and quantity of the material available for educational purposes have greatly improved. Anat Sci Educ. © 2013 American Association of Anatomists.  相似文献
