Europe’s information technology: Focus on Italy’s publishing industry

Conclusion: What is the future for Digital Publishing? It is very difficult to understand the real value of all the different business models that have been introduced to the market in this very chaotic and evolving arena. The recent disillusions with the Internet and the “new economy” downturn have also made the publishing industry very cautious of investing in new business ventures. Many new projects have been suspended or postponed because they were based only on estimated or assumed online revenues. Meanwhile, very real operating expenses far exceeded original estimates or start-up budgets while sources of revenues remained elusive. On a more positive note, inside all the major publishing houses there is a stronger knowledge of the importance of creating a digital content database. Traditional publishers are learning that their intellectual property and editorial content can be used for many different products and delivered in many different media. Probably in the next months one of the big strategic issues will be the integration between the traditional print on paper products as the viable revenue model with all the other digital media in development. Finally, the questions remains how the market will accept as well as pay for content in different digital formats?     

Objective and subjective methods for quantifying training load in wheelchair basketball small-sided games

The aim of the present study was to analyse the training load in wheelchair basketball small-sided games and determine the relationship between heart rate (HR)-based training load and perceived exertion (RPE)-based training load methods among small-sided games bouts. HR-based measurements of training load included Edwards’ training load and Stagno’s training impulses (TRIMP_MOD) while RPE-based training load measurements included cardiopulmonary (session RPEres) and muscular (session RPEmus) values. Data were collected from 12 wheelchair basketball players during five consecutive weeks. The total load for the small-sided games sessions was 67.5 ± 6.7 and 55.3 ± 12.5 AU in HR-based training load (Edwards’ training load and TRIMP_MOD), while the RPE-based training loads were 99.3 ± 26.9 (session RPEres) and 100.8 ± 31.2 AU (session RPEmus). Bout-to-bout analysis identified greater session RPEmus in the third [P < 0.05; effect size (ES) = 0.66, moderate] and fourth bouts (P < 0.05; ES = 0.64, moderate) than in the first bout, but other measures did not differ. Mean correlations indicated a trivial and small relationship among HR-based and RPE-based training loads. It is suggested that HR-based and RPE-based training loads provide different information, but these two methods could be complementary because one method could help us to understand the limitations of the other.     

Feasibility and concurrent validity of a cardiorespiratory fitness test based on the adaptation of the original 20 m shuttle run: The 20 m shuttle run with music

ABSTRACT

The purpose was to examine the feasibility of the 20m shuttle run test with music and to test its concurrent validity with the original 20m shuttle run test. A total of 386 adolescents (14.5±1.6 years old, 48.9% boys) participated in our study. A self-reported questionnaire was used to assess student’s perception about the 20m shuttle run test with music and the original and to assess perceived exertion. Participants performed randomly the 20m shuttle run test with music and original two weeks apart. Average and maximum heart rate were monitored with heart rate monitors. The 20m shuttle run with music was a feasible test for measuring cardiorespiratory fitness in adolescents. The concurrent validity showed mean differences of 5.1±14.6 for shuttles, 0.3±0.8 km/h for speed, 0.5±4.1 for stages, and 1.5±4.1 for VO2max (all p<0.001) in favour of the 20m shuttle run with music vs. the original 20m shuttle run test. Mean difference for the rating of perceived exertion was 0.4±2.5 points (p=0.003). No significant difference was found between boys and girls. In conclusion, the 20mSRT-music is feasible and presents a good concurrent validity in adolescents, independently of the sex and it will be an alternative and good approach to assess cardiorespiratory fitness.     

Protective role of 17-β-estradiol towards IL-6 leukocyte expression induced by intense training in young female athletes

Abstract

Exercise performed at a competitive level could deeply modify the immune system and the cytokine response of athletes. In this report, we demonstrated that young elite female artistic gymnasts (n = 16; age: 9–15 years) showed an increase of interleukin 6 (IL-6) and tumour necrosis factor alpha (TNF-α) mRNA expression in blood mononuclear cells (PBMCs), in comparison to girls performing the same sport at a recreational level (n = 16; age: 10–15 years). The increase of IL-6 and TNF-α mRNAs appeared to be directly linked to the intensity and duration of the training. Moreover, in elite athletes engaged in artistic gymnastics or in synchronised swimming (n =34; age: 9–15 years), IL-6 gene expression appeared to be modulated by the levels of circulating oestrogens: pre-pubertal athletes (n = 20; age: 11 ± 1 years) revealed a higher increase in IL-6 than pubertal athletes (n = 14; age: 14 ± 1.6 years). In pre-pubertal athletes, body mass index (BMI) percentile was inversely correlated with the increase of both IL-6 and TNF-α. The consequence of these events was the shift of the cytokine profile towards a pro-inflammatory status. These modifications, induced by training performed at an elite level, might negatively affect the growth of female children athletes.     

Children’s participation and agency in Italian residential care for children: Adult-child interactions at dinnertime

This paper analyzes the impact of adults’ interactive moves and strategies on children’s participation and agency at dinnertime in two Italian residential care facilities, one of the most widely used alternative care life-context for children and youth coming from vulnerable families. Participants are 14 children and 11 educators living in two residential care facilities in Rome (Italy). Adopting an interactional and multimodal analytic approach, this paper focuses on two dinnertime activities: the routine activity of praying before eating and the very frequent one of talking about rules and transgressions. The comparative analysis of the two facilities shows how, in stable patterns of adult-child interactions recurring across different activities in the same facility, adults’ strategies and interactive maneuvers differently impact on children’s participation and agency and consequent socialization practices. In the conclusion, we emphasize the relevance and implications of this study for either research in educational sciences and for professionals operating in alternative care and related fields.

Centering the Educational and Social Significance of HBCUs: A Focus on the Educational Journeys and Thoughts of African American Scholars

In this article we provide a brief history of historically Black colleges and universities (HBCUs) as a part of the sociopolitical context framing this special issue. The aim of this issue is to situate HBCUs as centers of leadership, change, and influence as well as repositories of Black education and the Black American experience through their legacy of intellectual, cultural, and communal engagement. We argue that the lived experiences of HBCU graduates provide a deeper understanding of their positionalities in the landscape of U.S. American higher education outcomes.     

Influence of regression model and initial intensity of an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and running performance

Abstract

This study investigated the influence of the regression model and initial intensity during an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and performance in elite-standard runners. Twenty-three well-trained runners completed a discontinuous incremental running test on a treadmill. Speed started at 9 km · h^?1 and increased by 1.5 km · h^?1 every 4 min until exhaustion, with a minute of recovery for blood collection. Lactate–speed data were fitted by exponential and polynomial models. The lactate threshold was determined for both models, using all the co-ordinates, excluding the first and excluding the first and second points. The exponential lactate threshold was greater than the polynomial equivalent in any co-ordinate condition (P < 0.001). For both models, the lactate threshold was lower when all co-ordinates were used than when the first and the first and second points were excluded (P < 0.001). 10-km race pace was correlated with both the exponential and polynomial lactate thresholds for all the co-ordinate conditions (r ≥ 0.75, P < 0.001 and r ≥ 0.56, P < 0.05, respectively). The results suggest that the exponential lactate threshold should be used instead of the polynomial equivalent since it is more strongly associated with performance and is independent of the initial intensity of the test.
