Stone consolidation: The role of treatment procedures   总被引：3，自引：0，他引：3  

A.P. Ferreira Pinto  J. Delgado Rodrigues   《Journal of Cultural Heritage》2008,9(1):38-53

Four types of carbonate stones and three consolidation products were used in a systematic study to assess the influence of the application procedures on the amount of product applied, as a primary step to evaluate consolidation treatments. Microdrilling, ultrasonic velocity and flexural resistance were used as performance indicators. The amount of product of a specific treatment and its action depend on the application procedures, both when the treatments are carried out in the laboratory and on site. The results are expected to contribute to the standardisation of testing protocols on stone consolidation.  相似文献   

Cortisol levels of caregivers in child care centers as related to the quality of their caregiving     

Elles J. de Schipper  J. Marianne Riksen-Walraven  Sabine A.E. Geurts  Carolina de Weerth 《Early childhood research quarterly》2009

The present study examined whether stress in professional caregivers – as reflected in salivary cortisol levels – is related to the quality of their caregiving behavior. The 221 professional female caregivers in 64 child care centers were observed in three different situations and saliva samples were taken three times during the morning. Results showed that higher levels of cortisol, particularly at the beginning of the workday, predicted lower-quality caregiver behavior beyond the contribution of three other predictors, namely a higher self-reported physical workload, more children under age two in the care group, and lower caregiver age. Contrary to the expectation, higher cortisol levels did not mediate the relation between higher self-reported physical workload and more children under age two on the one hand and lower-quality caregiving behavior on the other.  相似文献   

A role of team and organizational identification in the success of cause-related sport marketing     

Jaedeock Lee  Mauricio Ferreira 《Sport Management Review》2013,16(2):161-172

As sport marketers are increasingly engaging in cause-related sport marketing (CRSM) programs, there is a growing interest in understanding what CRSM characteristics and circumstances can lead to success. This study extends prior research by examining the direct and moderating impacts of team identification and cause organizational identification on consumer attitudes toward cause related sport marketing (CRSM) programs using intercollegiate sport contexts in the United States. A two groups (high vs. low-fit CRSM messages), between subject, and post-test only experiment (N = 309) denoted that respondents showed more positive attitudes toward high-fit CRSM messages and both team identification and cause organizational identification had different moderating effects of sport/cause fit on attitudes. Fit between a sport team and a cause had a greater impact on attitudes when consumer affinity toward the sport team was more positive. However, fit had little or no impact when consumer affinity toward the cause was positive, but it played a significant and positive role when consumers showed low affinity toward the cause.  相似文献   

Intelligence assessment: Gardner multiple intelligence theory as an alternative     

Leandro S. Almeida  Maria Dolores Prieto  Aristides I. Ferreira  Maria Rosario Bermejo  Mercedes Ferrando  Carmen Ferrándiz 《Learning and individual differences》2010,20(3):225-230

In the multiple intelligence framework, newer and more contextualized cognitive tasks are suggested as alternative to more traditional psychometric tests. The purpose of this article is to examine whether or not these two types of instruments converge into a general factor of cognitive performance. Thus, the Battery of General and Differential Aptitudes (BADyG: reasoning, memory, verbal aptitude, numerical aptitude and spatial aptitude) and a set of Gardner's multiple intelligence assessment tasks (linguistic, logical, visual/spatial, bodily-kinesthetic, naturalistic and musical intelligences) were administered to 294 children aged 5 to 7. The confirmatory factor analysis points out the absence of a common general factor considering both batteries, indicating instead the existence of two general factors, which gather the tests that encompass them. Also, these two general factors correspond to traditional and multiple intelligence assessments and show a statistically moderate correlation between them. These results challenge Gardner's original position on refusing a general factor of intelligence, especially when considering the cognitive dimensions measured which do not coincide with the more traditional tests of intelligence.  相似文献   

"I'm Not a Feminist...I Only Defend Women as Human Beings": The Production,Representation, and Consumption of Feminism in a Telenovela     

Carolina Acosta-Alzuru 《Critical Studies in Media Communication》2013,30(3):269-294

This study examines a successful Latin American media product - the Venezuelan telenovela El País de las Mujeres [The Country of Women] - and analyzes how feminism and feminists are represented in it. Through interviews with the head writer and actors, the study also explores the production of these portrayals. In addition, consumption of the serial's representation of feminism is analyzed through individual and group interviews with audience members. The study highlights the paradoxes involved in the production and consumption of a media text that simultaneously delivers a critique of Venezuelan patriarchy, an empowering message for women, and a sharp rejection of feminism.  相似文献   

Strategic knowledge management, innovation and performance     

Carolina López-Nicolás  Ángel L. Meroño-CerdánAuthor vitae 《International Journal of Information Management》2011,31(6):502-509

Our aim is to shed light on the consequences of knowledge management (KM) strategies on firm's innovation and corporate performance. Organisations are not aware of the real implications that KM may have. Based on an empirical study consisted of 310 Spanish organisations and structural equations modelling, results show that both KM strategies (codification and personalisation) impacts on innovation and organisational performance directly and indirectly (through an increase on innovation capability). Also, findings demonstrate a different effect of KM strategies on diverse dimensions of organisational performance. Our conclusions may help academics and managers in designing KM strategic programs in order to achieve higher innovation, effectiveness, efficiency and profitability.  相似文献   

Competitive State Anxiety Inventory-2 (CSAI-2): Evaluating the Swedish version by confirmatory factor analyses     

Carolina Lundqvist  Peter Hassmén 《Journal of sports sciences》2013,31(7):727-736

The Competitive State Anxiety Inventory-2 (CSAI-2) is one of the most frequently used instruments when assessing competitive state anxiety in sport psychology research. However, doubts have been expressed about the factorial validity of both the English and the Greek versions of the scale. Hence, a revised version of the inventory (CSAI-2R) has recently been suggested to be more psychometrically sound (Cox et al., ). In the present study, the aim was to evaluate the psychometric properties of the Swedish version of the CSAI-2 using confirmatory factor analyses. A total of 969 athletes (571 men and 398 women) competing in 26 different sports completed the Swedish version of the CSAI-2. Three different factor structures were evaluated: the original three-factor model (with cognitive anxiety, somatic anxiety and self-confidence), a two-factor model in which self-confidence was excluded, and a three-factor model containing 17 items (CSAI-2R). The results revealed that only the 17-item model displayed an acceptable fit to the data. Although some doubts remain about the amount of variance that can be attributed to error variance in the subscales, the results suggest that it is better to use the CSAI-2R rather than the original CSAI-2.  相似文献   

Home advantage in judo: A study of the world ranking list     

Ursula Ferreira Julio  Valéria Leme Gonçalves Panissa  Bianca Miarka  Monica Yuri Takito  Emerson Franchini 《Journal of sports sciences》2013,31(2):212-218

Abstract

In 2009, the International Judo Federation established a ranking system (RS) to classify athletes and to distribute the competitor quotas of the Olympic Games. However, the RS does not consider the home advantage. This issue has not been studied in judo, and its implications for the RS have not been determined. The objective was to verify the home advantage in judo in terms of winning a medal or the number of matches won. Therefore, 25 competitions that computed points for the RS in 2009 were analysed. Logistic regression analysis and the Poisson generalised linear model were used for the analyses, which included the relative quality of the athletes. The sample was composed only of athletes who had competed both at home and away. The odds ratio for winning medals was higher for athletes who competed at home for both males and females. The association between the number of matches won and competing at home was significant only for the male athletes. The home advantage was observed in the competitions that used the judo RS. Thus, it is likely that athletes from countries that host competitions using the RS have an advantage in terms of obtaining their Olympic classification.  相似文献   

Modelling the dynamics of children’s gross motor coordination

ABSTRACT

This study modelled children’s gross motor coordination, investigated sex-differences and identified the effects of fixed and dynamic correlates on motor coordination development. A total of 344 Portuguese children (170 girls), from 6 age cohorts (5 to 9 years of age), were followed consecutively for three years (age range 5 to 11 years) using a mixed-longitudinal cohort design. Birth weight, hand dominance and socioeconomic status (SES) were identified. Gross motor coordination, body mass index, physical fitness (PF) and physical activity (PA) were assessed annually. A sequence of multilevel hierarchical linear models were developed. Model 1 found that age, age², sex, sex-by-age and sex-by-age² were significant predictors (p < 0.05) of gross motor coordination. Boys outperformed girls from 6 years of age onwards. Model 2 found a cohort effect (p < 0.05). Model 3 found that right handers were more coordinated (p < 0.05). When the confounders of body mass index, PF and PA were added to the model (Model 4) it was found that boys and girls had parallel trajectories in their gross motor coordination development. In conclusion children with increasing body mass index were less coordinated, while those who were stronger and more agile had steeper trajectories of gross motor coordination with age.  相似文献   

Differences in maturity,morphological and physical attributes between players selected to the primary and secondary teams of a Portuguese Basketball elite academy     

Sérgio Ramos  Anna Volossovitch  António Paulo Ferreira  Isabel Fragoso  Luís Massuça 《Journal of sports sciences》2019,37(15):1681-1689

The present study aims (i) to compare the maturational, morphological and fitness attributes of young basketball players of primary and secondary teams of an elite basketball academy, and (ii) to identify the set of morphological and fitness attributes which better discriminate the players from the two teams. A total of 116 male basketball players of an elite basketball academy were divided into primary (team A) and secondary (team B) teams in two age groups (U-14 and U-16). All the players were evaluated during two consecutive seasons and data related to players’ practice experience, maturational, morphological and fitness attributes were collected at the beginning of the competition period. The results of the study suggest that: (i) in both age categories, team A players were older, more mature, bigger in size and had greater fitness profiles than team B players; (ii) stature and abdominal resistance were identified as discriminant attributes for youth basketball player performance; (iii) aerobic capacity for U-14 and agility for U-16 were identified as specific discriminant attributes for performance in youth basketball. Coaches are recommended to avoid premature talent identification and provide players with opportunities to progress through the talent pathway, at least until U-16 age category.  相似文献
