Brazil: Has the Country of the Future Become the Country of the Present for Book Publishing?     

Carlo?CarrenhoEmail author 《Publishing Research Quarterly》2015,31(1):54-63

This article analyses the growth of the Brazilian book market in the decade from 2004 to 2013 and compares it to Brazil’s GNP growth. It also studies the recent developments of three factors that should contribute to the performance of the Brazilian book industry: the growth of the middle class, the decrease of functional illiteracy and the higher number of college institutions and college students in the country. This article shows that despite these factors, the Brazilian book industry is underperforming and not living up to its potential.  相似文献   

Development of a cultural self-efficacy scale for adolescents (CSES-A)

We developed a cultural self-efficacy scale for adolescents (CSES-A) and tested its psychometric properties using both exploratory and confirmatory factor analyses. Cultural self-efficacy (CSE) was defined as person's perception of his/her own capability to function effectively in situations characterized by cultural diversity. On the basis of Bandura's guideline for the development of a domain-specific self-efficacy measure, we tailored 50 items after reviewing literature about cultural competence, adolescents’ school-problems and social self-efficacy scales developed in previous studies in intercultural contexts. After pre-testing and analyzing psychometric properties of the scale, we selected 33 items. Eight hundred sixty-eight adolescents with five different cultural origins completed a set of questionnaires, including the CSES-A, internal control expectancies, general self-efficacy, academic expectancies, number of people from diverse cultures they keep in touch with, acculturation attitudes, perceived enrichment of other cultures, acculturation stress and demographic data. An EFA with MPLUS 2.14 highlighted a five-factor solution with 25 items that was supported by a subsequent CFA. The five factors were: self-efficacy in mixing satisfactorily with other cultures, in understanding different ways of life, in processing information from other cultures, in coping with loneliness and in learning and understanding other languages. The pattern of correlation with internal control expectancies, general self-efficacy and cultural variables supported the validity of the scale. CSES-A may be useful for future research on multicultural contexts, in which self-efficacy in cultural adaptation could be a fundamental variable.  相似文献   

Factors influencing physiological responses to small-sided soccer games   总被引：3，自引：2，他引：1

The aim of this study was to examine the effects of exercise type, field dimensions, and coach encouragement on the intensity and reproducibility of small-sided games. Data were collected on 20 amateur soccer players (body mass 73.1 +/- 8.6 kg, stature 1.79 +/- 0.05 m, age 24.5 +/- 4.1 years, VO(2max) 56.3 +/- 4.8 ml x kg(-1) x min(-1)). Aerobic interval training was performed during three-, four-, five- and six-a-side games on three differently sized pitches, with and without coach encouragement. Heart rate, rating of perceived exertion (RPE) on the CR10-scale, and blood lactate concentration were measured. Main effects were found for exercise type, field dimensions, and coach encouragement (P < 0.05), but there were no interactions between any of the variables (P > 0.15). During a six-a-side game on a small pitch without coach encouragement, exercise intensity was 84 +/- 5% of maximal heart rate, blood lactate concentration was 3.4 +/- 1.0 mmol x l(-1), and the RPE was 4.8. During a three-a-side game on a larger pitch with coach encouragement, exercise intensity was 91 +/- 2% of maximal heart rate, blood lactate concentration was 6.5 +/- 1.5 mmol x l(-1), and the RPE was 7.2. Typical error expressed as a coefficient of variation ranged from 2.0 to 5.4% for percent maximal heart rate, from 10.4 to 43.7% for blood lactate concentration, and from 5.5 to 31.9% for RPE. The results demonstrate that exercise intensity during small-sided soccer games can be manipulated by varying the exercise type, the field dimensions, and whether there is any coach encouragement. By using different combinations of these factors, coaches can modulate exercise intensity within the high-intensity zone and control the aerobic training stimulus.  相似文献   

Preservation of visual attention in older expert orienteers at rest and under physical effort   总被引：1，自引：0，他引：1  

Pesce C  Cereatti L  Casella R  Baldari C  Capranica L 《运动与训练心理学杂志》2007,29(1):78-99

This study investigated the visual attention of older expert orienteers and older adults not practicing activities with high attentional and psychomotor demands, and considered whether prolonged practice of orienteering may counteract the age-related deterioration of visual attentional performance both at rest and under acute exercise. In two discriminative reaction time experiments, performed both at rest and under submaximal physical workload, visual attention was cued by means of spatial cues of different sizes followed, at different stimulus-onset asynchronies, by compound stimuli with local and global target features. Orienteers, as compared to nonathletes, showed a faster reaction speed and a complex pattern of attentional differences depending on the time constraints of the attentional task, the demands on endogenous attentional control, and the presence or absence of a concomitant effortful motor task. Results suggest that older expert orienteers have developed attentional skills that outweigh, at least at rest, the age-related deficits of visual attentional focusing.  相似文献   

Cycling shoe aerodynamics     

Giuseppe Gibertini  Donato Grassi  Carlo Macchi  Giuseppe De Bortoli 《Sports Engineering》2010,12(3):155-161

The present paper describes the activity carried out to investigate the aerodynamic effects of cycling shoes for time trial competitions. This subject has not been widely studied but can be important for an accurate aerodynamic optimisation of a time trial cyclist. The study was carried out by means of wind tunnel testing: an appropriate test setup and an appropriate test procedure (based on “effective angle of attack approach”) were developed in order to produce realistic test conditions. The developed testing procedure was applied to two different shoe models, differently fastened. Furthermore, an important point was the investigation of the overshoe effect. The results showed that the power required to overcome the shoe’s drag is almost a tenth of the total power and that differences between the shoes can affect the cyclist’s performance.  相似文献

The social life of Learning Analytics: cluster analysis and the ‘performance’ of algorithmic education     

Carlo Perrotta  Ben Williamson 《Learning, Media and Technology》2018,43(1):3-16

This paper argues that methods used for the classification and measurement of online education are not neutral and objective, but involved in the creation of the educational realities they claim to measure. In particular, the paper draws on material semiotics to examine cluster analysis as a ‘performative device’ that, to a significant extent, creates the educational entities it claims to objectively represent through the emerging body of knowledge of Learning Analytics (LA). It also offers a more critical and political reading of the algorithmic assemblages of LA, of which cluster analysis is a part. Our argument is that if we want to understand how algorithmic processes and techniques like cluster analysis function as performative devices, then we need methodological sensibilities that consider critically both their political dimensions and their technical-mathematical mechanisms. The implications for critical research in educational technology are discussed.  相似文献   

GovQual: A quality driven methodology for E-Government project planning     

Carlo Batini  Gianluigi Viscusi  Daniela Cherubini 《Government Information Quarterly》2009

We present a multidisciplinary methodology for E-Government project planning. The set of expertise needed for the design of E-Government systems includes social, juridical, economic, organizational, and technological perspectives. To properly address such a broad range of influences requires a unique vision. Our long-term aim is to use an integrated approach to examine a number of issues which currently present challenges in many E-Government projects. This paper in particular focuses on social and technological aspects of E-Government. The methodology has four phases: (1) state reconstruction, (2) quality assessment, (3) new quality targets definition, and (4) preliminary operational planning. A case study provides evidence of the feasibility and effectiveness of the methodology.  相似文献   

Anthropometry and body composition of female handball players according to competitive level or the playing position     

Chiara Milanese  Francesco Piscitelli  Chiara Lampis  Carlo Zancanaro 《Journal of sports sciences》2013,31(12):1301-1309

Abstract

Anthropometry and body composition were investigated in 43 female handball players from the Italian championships, grouped according to their competitive level (elite vs. sub-elite) or their playing position [goalkeeper (n = 7), back (n = 14), wing (n = 18), or pivot (n = 4)]. The anthropometry consisted of several circumferences, lengths, widths, and skinfold measurement at six sites; the regional and total body compositions were assessed by means of dual-energy X-ray absorptiometry (DXA). One-way ANOVA was used for statistical analysis, with a Bonferroni post-hoc test where needed. The results showed that elite players have significantly lower percentages of fat and higher bone mineral content than sub-elite as well as a clear tendency to accrue more lean mass, especially in upper limbs. Overall, the physical characteristics and body composition of handball players in Italy compared unfavourably with those in other countries, suggesting a need for improved selection and training. When playing position was included in the analysis of the whole group of handball players (n = 43) significant differences were found between the stature, mass, body mass index (BMI), several skinfolds, circumferences and lengths, and total body mineral mass, lean mass and fat mass of players in different positions. Post-hoc analysis suggests that players on the wing and in goalkeeper positions differed most from one another. These findings confirm and expand on previous data about the presence of anthropometric differences within playing positions in handball.  相似文献   

Effects of competition level on the centre forward role of men's water polo     

Corrado Lupo  Carlo Minganti  Cristina Cortis  Fabrizio Perroni  Laura Capranica  Antonio Tessitore 《Journal of sports sciences》2013,31(9):889-897

Abstract

This study aimed to compare specific technical and tactical indicators of the team and centre forward role of Euro League, and Italian Serie A1, Serie A2, and Serie B men's water polo club competitions. A notational analysis was performed on 21 water polo matches to evaluate the occurrence of technical and tactical team and centre forward indicators, highlighting differences among championships according to chi-square analyses. Differences emerged for Counterattack (P < 0.001) and Power-Play (P < 0.001) possessions, Even (P < 0.001; Euro League: 3 ± 1, Serie A1: 3 ± 2, Serie A2: 3 ± 2, Serie B: 6 ± 4) and Power-Play (P = 0.001) goals, and exclusions and penalties (P = 0.008) of the team during Even possessions. Relatively to the role analyses, effects emerged for perimeter players playing events (P = 0.049), as well as for centre forwards' goals (P = 0.007) and exclusions and penalties (P < 0.001; Euro League: 8 ± 1, Serie A1: 6 ± 2, Serie A2: 6 ± 2, Serie B: 3 ± 2) occurring at the end of Even possessions. Therefore, in Euro League, and Italian Serie A1 and Serie A2, teams perform a high occurrence of Power-Play possessions following up an exclusion, especially achieved by the centre forward during Even possessions, while, in Italian Serie B, goals were mostly scored during Even possessions, with a relevant contribution from the centre forward role.  相似文献
