The Bologna Process and higher education in Mercosur: regionalization or Europeanization?

Over the past two decades regional agreements have become more significant in educational and training. This paper situates and analyses the European Higher Education Area (EHEA), the Bologna Process and the Lisbon Strategy and explores their influence on the integration of higher education systems in Mercosur (the Southern Common Market of Argentina, Brazil, Paraguay, Uruguay and Venezuela). Mercosur is still a customs union, and the project of integrating higher education is at an early stage. Lacking organically established regional bodies, coordination of integration in Mercosur has focused on summits and meetings of officials. However, in a context of unequal maturity in regional integration, there is emerging evidence that the EHEA project is influencing the reforms of national systems of higher education and even Mercosur’s model for a regional area of higher education. A nascent Europeanization of higher education systems in the Mercosur region is emerging, by-passing Mercosur’s regional structures. The formulation of policies has been permeated by policy transfer from Europe to national territories within Mercosur.     

Spatial-temporal constraints on decision-making during shooting performance in the team sport of futsal

Abstract

In this paper we examined the influence of opposing players constraining the decision-making of an attacker during shooting performance in futsal. Performance during 10 competitive matches was recorded and examined from the moment a shot was taken until the ball was intercepted or entered the goal in sequences of play: ending in a goal, a goalkeeper's save, or an interception by the nearest defender. The variables under scrutiny in this study were (i) the distance of each player to the ball's trajectory, (ii) the time for the ball to arrive at that same point (i.e. the interception point), and (iii), the required movement velocity of the nearest defender and the goalkeeper to intercept the ball. Results showed that values of distance from a defender and goalkeeper to the interception points were significantly lower when they intercepted the ball. The time of ball arrival at the interception point of the defender was also lower when the ball was intercepted. The required velocities of the nearest outfield defender and the goalkeeper to intercept the ball were significantly lower during plays in which they intercepted the ball, than in plays in which the ball was not intercepted. Our results suggest that researchers and practitioners should consider simultaneously both space and time in analysis of interceptive actions in team sports. The required movement velocities of the opponents to intercept the ball are reliable spatial-temporal variables constraining decision-making during shooting performance in team sports like futsal.     

Assessment of passive drag in swimming by numerical simulation and analytical procedure

The aim was to compare the passive drag-gliding underwater by a numerical simulation and an analytical procedure. An Olympic swimmer was scanned by computer tomography and modelled gliding at a 0.75-m depth in the streamlined position. Steady-state computer fluid dynamics (CFD) analyses were performed on Fluent. A set of analytical procedures was selected concurrently. Friction drag (D_f), pressure drag (D_pr), total passive drag force (D_f+pr) and drag coefficient (C_D) were computed between 1.3 and 2.5 m · s^?1 by both techniques. D_f+pr ranged from 45.44 to 144.06 N with CFD, from 46.03 to 167.06 N with the analytical procedure (differences: from 1.28% to 13.77%). C_D ranged between 0.698 and 0.622 by CFD, 0.657 and 0.644 by analytical procedures (differences: 0.40–6.30%). Linear regression models showed a very high association for D_f+pr plotted in absolute values (R² = 0.98) and after log–log transformation (R² = 0.99). The C_D also obtained a very high adjustment for both absolute (R² = 0.97) and log–log plots (R² = 0.97). The bias for the D_f+pr was 8.37 N and 0.076 N after logarithmic transformation. D_f represented between 15.97% and 18.82% of the D_f+pr by the CFD, 14.66% and 16.21% by the analytical procedures. Therefore, despite the bias, analytical procedures offer a feasible way of gathering insight on one’s hydrodynamics characteristics.     

Non-linear resistance training reduces inflammatory biomarkers in persons living with HIV: A randomized controlled trial

The purpose of this study is to analyse the effect of 12 weeks of non-linear resistance training (NLRT) on anthropometry, muscle strength and inflammatory biomarkers in persons infected with human immunodeficiency virus (PIHIV). Thirty previously sedentary PIHIVs were randomized into the NLRT (n?=?15) and control (CON, n?=?15) groups. NLRT group were submitted to 12 weeks of training, whereas the CON group maintained their daily habits. At baseline and after 12 weeks, both groups underwent anthropometric evaluations and blood sampling for the analysis of inflammatory biomarkers. Analysis of covariance using preintervention values as covariate was performed to determine the effects of exercise on anthropometry, muscle strength, cytokines levels and T cells. Significance was set at p?p?p p?=?.009), blood levels of interleukin (IL)-1β (p?=?.029), IL-6 (p?=?.005), IL-8 (p?=?.010), and tumour necrosis factor (TNF)-α (p?=?.001) and an increase in muscle strength (p?p?=?.030) and CD4⁺ (p?=?.004) and CD8⁺ (p?相似文献

Let the Aryanists know! Brazilian race and nation in the 1938 France World Cup

ABSTRACT

Getúlio Vargas’ dictatorship (1937-1945) attributed to sports a key role to foment the formation of a ‘new Brazil’, using football as a crucial element to promote the state nationalist policy. A propitious moment for this attempt would be an international event, a space in which Brazil could demonstrate to the civilized nations – especially to the European countries – the best qualities of ‘the Brazilian race’. This arena was the 1938 World Cup, played in France. This essay presents some aspects of the relationship between football and the construction of Brazil’s national identity in the early twentieth century. My focus on the 1938 World Cup is due to the fact this was a quintessential event not only for the history of Brazilian sports but also for the debates on scientific racism and the construction of national identity. This event shaped, more than eight decades ago, the ways through which football articulated the core commonality of the Brazilian society, becoming one of the key elements to understand contemporary Brazil.     

Deacidification of paper using dispersions of Ca(OH)2 nanoparticles in isopropanol. Study of efficiency

The efficiency of a recently described non-aqueous method for paper deacidification using Ca(OH)₂ nanoparticles in isopropanol was evaluated by pH and colorimetric measurements and by the analysis of the degree of polymerization (DP). Samples of plain paper and paper with iron gall ink were tested. The results were compared with non treated samples and samples submitted to the traditional treatment with saturated aqueous Ca(OH)₂ solution. By comparing the two conservation methods, the aqueous one shows higher neutralization reaction kinetics than the non-aqueous one. The iron gall ink samples maintain their coloration closer to the original after the non-aqueous Ca(OH)₂ nanoparticles treatment, in contrary to the aqueous treatment that changes the ink aesthetics considerably. Artificial aging tests revealed a general increase in the aging stability of deacidified paper samples. The Ca(OH)₂ nanoparticles treatment can be an alternative for papers who can not be treated by the classical aqueous treatment, e.g. papers with water soluble components.     

Output-feedback binary adaptive control of MIMO systems using monitoring function

The problem of adaptive control design for multivariable linear time-invariant plants with unknown control direction is considered. A solution is proposed based on the SDU factorization of the high frequency gain matrix (HFG) and the monitoring function approach. The adaptation scheme is the binary model reference adaptive control (BMRAC) which utilizes parameter projection and sufficiently high adaptation gains. The signs of the leading principal minors of the HFG define the control directions, and the lack of knowledge of which is a major challenge in the multivariable framework. The role of the monitoring function is to monitor the output error transient and then provide the necessary changes of the adaptation gain signs to guarantee a stable adaptive control. In addition to proving the signal boundedness of the resulting closed-loop system, the output tracking error is shown to be asymptotically as well as exponentially practically stable, i.e., exponentially stable with respect to a small residual compact set of size inversely proportional to the BMRAC adaptation gain. The latter implies good transient properties of the output tracking error in contrast to conventional adaptive laws which only guarantee asymptotic stability but can lead to extremely slow error convergence. The extension of the proposed approach to matched disturbances is also briefly discussed following the classical paradigm of disturbance estimators. Numerical results with a visual servoing application illustrate the efficiency of the proposed method.
