The Moral Controversy Over Boxing Reform     

C.D. Herrera 《体育哲学杂志》2013,40(2):163-173

Lesbian athletes, no matter their gender performances, are viewed as masculine. The on-court persona of Amélie Mauresmo illustrates this. Even though Mauresmo’s gender expression was indistinguishable from other women on the pro tennis tour, her sexuality, being an out lesbian, led the public to view her as masculine. Judith Butler’s ‘heterosexual matrix’ (a sex-gender-sexuality tripartite system) accounts for how we make assumptions based on what we see. Her theory explains the experiences of most people, where sex and gender are the known categories, so the viewer, then, assumes a particular sexuality. However, the concept does not work for people who are out, when the known categories are sex and sexuality. This leads the viewer to assume a particular gender and, for Mauresmo, the assumed gender was masculinity. This paper transforms Butler’s theory, extending the usefulness of her ‘heterosexual matrix’.  相似文献   

Metric multidimensional scaling and automatic message generation applied to the tourism industry: The case of Israel     

Felipe Korzenny  N.J Stoyanoff  Martin Ruiz  Amnon Ben David 《Int J Intercult Relat》1980,4(1):77-95

The present paper demonstrates the use of metric multidimensional scaling analysis to determine messages which could be utilized to enhance tourism for a particular region. An example utilizing the case of Israel is studied here in order to illustrate these techniques. Thirty professors and their spouses were interviewed to obtain ratio estimates of differences among 16 concepts associated with the focal concepts of “Israel” and “my vacation.” Data were analyzed using the metric program GALILEO (T.M.), which rendered a ratio-scaled configuration of the concepts in a multidimensional space. Further, using an algorithm called the Automatic Message Generator (T.M.), messages were formulated which would move “my vacation” closer to “Israel.” The techniques and the results are presented so as to make them relevant to those persons in charge of the generation of messages in the tourism industry. It is argued in this paper that the use of these techniques may facilitate the task of assessing and changing the attitudes of individuals with regard to their vacation preferences.  相似文献   

Study persistence and academic achievement as a function of the type of competing tendencies     

Willy Lens  Marlies Lacante  Maarten Vansteenkiste  Dora Herrera 《European Journal of Psychology of Education - EJPE》2005,20(3):275-287

In order to understand and predict students’ achievement and persistence at learning activities, many contemporary motivational models consider how much students are motivated for their school work. However, students’ achievement and persistence might not only be affected by their amount of study motivation, but also by the motivation to engage in competing alternative activities, as suggested three decades ago by Atkinson and Birch in their “Dynamics of Action” (1970). Building on this line of theorizing, the present contribution indicates that it is not only instructive to consider the level of students’ motivation for these competing activities, but also the type of activities they engage in, that is leisure vs. working activities. Two studies demonstrated that whereas time spent on working activities is inversely related to study motivation, attitude, persistence and academic achievement, such relationships were not found for leisure time engagement. Spending some time on leisure time activities does not interfere with optimal learning.  相似文献   

Long-Term Effects of Food Supplementation and Psychosocial Intervention on the Physical Growth of Colombian Infants at Risk of Malnutrition     

Charles M. Super  M. Guillermo Herrera  José O. Mora 《Child development》1990,61(1):29-49

280 Colombian infants at risk of malnutrition were randomly assigned to 1 of 4 experimental groups formed by the presence/absence of 2 interventions: (1) food supplementation for the entire family, from mid-pregnancy until the target child was 3 years old, and (2) a twice-weekly home-visiting program to promote cognitive development, from birth until age 3. All families received free medical care and were studied prospectively. At 3 years of age, children who had received food supplementation averaged 2.6 cm and 642 grams larger than controls. Home visiting and supplementation together reduced the number of children with severe growth retardation. 3 years after intervention (age 6), supplementation effects remained. Children in the home visit condition had become larger than controls, by 1.7 cm and 448 grams. The interactive effect to reduce stunting was marginally significant at this age, and the overall distribution of scores was improved. Other results suggest that changes in family functioning as well as biological mechanisms account for the observed pattern of results.  相似文献   

Conflict, Understanding, and Relationships: Developments and Differences in the Preschool Years     

Judy Dunn  Cheryl Slomkowski  Nancy Donelan  Carla Herrera 《Early education and development》1995,6(4):303-316

Children's conflict management in three close relationships was studied longitudinally in 38 second born children, observed at home with their mothers and siblings at 33 months and at 47 months, and with friends at 47 months. Children used significantly more other-oriented argument with friends than with their mothers or siblings. Their use of reasoned argument with their siblings, but not their mothers, was related to their emotional understanding assessed formally at 40 months. The emotional context of conflict interactions was found to be important as an influence on children's use of reasoned argument, with less reasoning shown by children when they were upset at 33 months. The differences in patterns over time and in links with emotional understanding for these different relationships is discussed, and the significance of child-child interaction in the development of social understanding is highlighted.  相似文献   

Communities of Caring: Developing Curriculum That Engages Latino/a Students’ Diverse Literacy Practices     

Rosario Ordoñez-Jasis  KaiLonnie Dunsmore  George Herrera  Carlos Ochoa  Laura Diaz 《Journal of Latinos & Education》2016,15(4):333-343

This study investigates the learning and work of a community of practice that engaged in a specific inquiry around family/community literacy and the development of a culture of caring that would connect family/community/school literacies in ways that allowed their mostly Latino/a students to develop positive student identities, enhanced personal connections to their peers, and stronger experiential responses to literacy instruction.  相似文献   

Wavelet-based deconvolution of ultrasonic signals in nondestructive evaluation   总被引：1，自引：0，他引：1  

OROZCO Rubén 《浙江大学学报(A卷英文版)》2006,7(10):1748-1756

INTRODUCTION Deconvolution of ultrasonic signals is defined as the solution of the inverse problem of convolving an input signal, known as the system function h(n), with a medium reflectivity function x(n) and can be rep- resented by y(n)=h(n)*x(n) η(n), (1) where y(n) is the measured signal, * denotes the convolution operation and η(n) is the additive noise. Recovering x(n) from the observation y(n) leads to improving the appearance and the axial resolution of the RF-signals by removin…  相似文献   

Gender differences in the risk for delinquency among youth exposed to family violence     

Herrera VM  McCloskey LA 《Child abuse & neglect》2001,25(8):1037-1051

OBJECTIVE: The purpose of this research was to illuminate gender differences in adolescent delinquency against a backdrop of childhood exposure to both marital violence and physical child abuse. Specifically, analyses were performed to trace the unique effects of exposure to either form of family violence (marital or child) on the violent and nonviolent delinquency of boys and girls. METHOD: This is a prospective study of 299 children who were interviewed with their mothers in 1991 about forms of abuse in the family. Approximately 5 years later a search of juvenile court records was performed for these same children. Details on the nature of the crimes were collected. Outcome variables included: (1) whether there was ever an arrest; and (2) whether there was ever an arrest for a violent crime. RESULTS: Preliminary analyses indicated no gender differences in overall referral rates to juvenile court, although boys were more likely than girls to be referred for property, felony, and violent offenses. Exposure to marital violence in childhood predicted referral to juvenile court. Girls with a history of physical child abuse were arrested for violent offenses more than boys with similar histories, but the context of violent offenses differed dramatically by gender: Nearly all referrals for a violent offense for girls were for domestic violence. CONCLUSIONS: Although boys and girls share similar family risk factors for delinquency, girls are more likely than boys to be arrested for violent offenses in the aftermath of child physical abuse. These findings suggest that it takes more severe abuse to prompt violence in girls than is necessary to explain boys' violent offending.  相似文献   

High-frequency resistance training does not promote greater muscular adaptations compared to low frequencies in young untrained men     

Cintia Barcelos  Felipe Damas  Sanmy Rocha Nóbrega  Carlos Ugrinowitsch  Manoel Emílio Lixandrão  Lucas Marcelino Eder Dos Santos 《European Journal of Sport Science》2018,18(8):1077-1082

The aim of the study was to compare the effect of resistance training (RT) frequencies of five times (RT5), thrice- (RT3) or twice- (RT2) weekly in muscle strength and hypertrophy in young men. Were used a within-subjects design in which 20 participants had one leg randomly assigned to RT5 and the other to RT3 or to RT2. 1?RM and muscle cross-sectional area (CSA) were assessed at baseline, after four (W4) and eight (W8) RT weeks. RT5 resulted in greater total training volume (TTV) than RT3 and RT2 (P?=?.001). 1?RM increased similarly between protocols at W4 (RT5: 55?±?9?Kg, effect size (ES): 1.18; RT3: 51?±?11?Kg, ES: 0.80; RT2: 54?±?7?Kg, ES: 1.13; P?P?2, ES: 0.54; RT3: 22.0?±?4.6?cm², ES: 0.19; RT2: ES: 0.25; 23.8?±?3.8?cm²; P?2; ES: 0.69; RT3: 23.6?±?4.2?cm², ES: 0.58; RT2: 25.5?±?3.7?cm²; ES: 0.70; P?2; RT3: 21.2?±?4.0?cm²; RT2: 22.9?±?3.8?cm²). Performing RT5, RT3 and RT2 a week result in similar muscle strength increase and hypertrophy, despite higher TTV for RT5.  相似文献   

Improved similarity-based modeling for the classification of rotating-machine failures     

Matheus A. Marins  Felipe M.L. Ribeiro  Sergio L. Netto  Eduardo A.B. da Silva 《Journal of The Franklin Institute》2018,355(4):1913-1930

Similarity-based modeling (SBM) is a technique whereby the normal operation of a system is modeled in order to detect faults by analyzing their similarity to the normal system states. First proposed around two decades ago, SBM has been successfully used for fault detection in varied systems. In spite of this success, there is not much study performed in the literature regarding its design, that encompasses both similarity metrics and model training. This work aims at contributing with an in-depth study of SBM for fault detection considering these two design aspects. This is done in the context of proposing a novel system to identify rotating-machinery faults based on SBM, that is employed either as a standalone classifier or to generate features for a random forest classifier. New approaches for training the model and new similarity metrics are investigated. Experimental results are shown for the recently developed Machinery Fault Database (MaFaulDa) that has an extensive set of sequences and fault types, and for the Case Western Reserve University (CWRU) bearing database. Results for both databases indicate that the proposed techniques increase the generalization power of the similarity model and of the associated classifier, achieving accuracies of 98.5% on MaFaulDa and 98.9% on CWRU database.  相似文献
