Crossed looks: globalisations and curriculum in Guinea-Bissau

This article focuses on education in Guinea-Bissau in the context of globalisations, examining the concept of globalisation and its relation to education and the curriculum. It focuses on the relatively neglected area of national education policies in Guinea-Bissau, comparing differences and common points of interference/influence of multilateral (international and regional) and bilateral organisations in these policies. Data collection was based on content analysis of a corpus of documents – the Education Act, the document of Portuguese Cooperation Programme, the Education Sector Policy Paper, the Education for All National Plan of Action, and Policy n. 3/2007/CM/UEMOA – and field notes collected from 2009 to 2012. The article argues that there is a tendency for the homogenisation of curriculum policies, at least at the macro-level, due to the different types of pressures coming from international/regional organisations.     

Dominant–non-dominant asymmetry of kicking a stationary and rolling ball in a futsal context

The aim of this study was to analyse the characteristics of the asymmetries in the dominant and non-dominant limbs when kicking stationary and rolling balls. Ten experienced Brazilian amateur futsal players participated in this study. Each participant performed kicks under two conditions (stationary ball vs. rolling ball) with the dominant and non-dominant limbs (five kicks per condition per limb). We analysed the kicking accuracy, ball and foot velocities, angular joint displacement and velocity. The asymmetry between the dominant and non-dominant limbs was analysed by symmetry index and two-way repeated measures ANOVA. The results did not reveal any interaction between the condition and limb for ball velocity, foot velocity and accuracy. However, kicking with the dominant limb in both kicks showed higher ball velocity (stationary ball: dominant – 24.27 ± 2.21 m · s^?1 and non-dominant – 21.62 ± 2.26 m · s^?1; rolling ball: dominant – 23.88 ± 2.71 m · s^?1 and non-dominant – 21.42 ± 2.25 m · s^?1), foot velocity (stationary ball: dominant – 17.61 ± 1.87 m · s^?1 and non-dominant – 15.58 ± 2.69 m · s^?1; rolling ball: dominant – 17.25 ± 2.26 m · s^?1 and non-dominant – 14.77 ± 2.35 m · s^?1) and accuracy (stationary ball: dominant – 1.17 ± 0.84 m and non-dominant – 1.56 ± 1.30 m; rolling ball: dominant – 1.31 ± 0.91 m and non-dominant – 1.97 ± 1.44 m). In addition, the angular joint adjustments were dependent on the limb in both kicks (the kicks with non-dominant limb showed lower hip external rotation than the kicks with the dominant limb), indicating that the hip joint is important in kick performance. In conclusion, the kicks with the non-dominant limb showed different angular adjustments in comparison to kicks with the dominant limb. In addition, kicking a rolling ball with the non-dominant limb showed higher asymmetry for accuracy, indicating that complex kicks are more asymmetric.     

Systematic characterization of degas-driven flow for poly(dimethylsiloxane) microfluidic devices

Degas-driven flow is a novel phenomenon used to propel fluids in poly(dimethylsiloxane) (PDMS)-based microfluidic devices without requiring any external power. This method takes advantage of the inherently high porosity and air solubility of PDMS by removing air molecules from the bulk PDMS before initiating the flow. The dynamics of degas-driven flow are dependent on the channel and device geometries and are highly sensitive to temporal parameters. These dependencies have not been fully characterized, hindering broad use of degas-driven flow as a microfluidic pumping mechanism. Here, we characterize, for the first time, the effect of various parameters on the dynamics of degas-driven flow, including channel geometry, PDMS thickness, PDMS exposure area, vacuum degassing time, and idle time at atmospheric pressure before loading. We investigate the effect of these parameters on flow velocity as well as channel fill time for the degas-driven flow process. Using our devices, we achieved reproducible flow with a standard deviation of less than 8% for flow velocity, as well as maximum flow rates of up to 3 nL∕s and mean flow rates of approximately 1-1.5 nL∕s. Parameters such as channel surface area and PDMS chip exposure area were found to have negligible impact on degas-driven flow dynamics, whereas channel cross-sectional area, degas time, PDMS thickness, and idle time were found to have a larger impact. In addition, we develop a physical model that can predict mean flow velocities within 6% of experimental values and can be used as a tool for future design of PDMS-based microfluidic devices that utilize degas-driven flow.     

Career adaptability and associations with personality traits and pathological traits utilizing network analysis

This study investigated relationships between career adaptability and personality and pathological traits using the network analysis approach. We administered CAAS, BFI-2-S, and IDCP-2 to 630 working adults. We observed positive associations between personality and career adaptability and negative associations between pathological traits and career adaptability. This paper contributes to the understanding of the associations between career adaptability and Big Five personality traits and pathological traits. We found stronger associations between career adaptability and personality traits as compared to pathological traits. Our findings suggest that Neuroticism and Conscientiousness contribute more to adaptation to professional development tasks than do pathological traits.

     

Video self-modelling as an intervention for remediating dysgraphia in children with autism spectrum disorders

Abstract

A severe deficit in handwriting is known as dysgraphia, a problem frequently associated with autism spectrum disorder (ASD). Video self-modelling (VSM) has been proven effective for children with ASD in the strengthening of social skills, verbalizations, and daily living skills. Because VSM has demonstrated success in the acquisition of many types of skills, it may prove similarly effective for remediating dysgraphia in children with ASD. Utilizing a single-subject design with three 7–8 year old children diagnosed with ASD, this study examined VSM as a treatment for improving handwriting legibility and proficiency. All participants’ legibility data showed a large effect sizes and high Percentages of non-overlapping data from baseline to treatment and maintenance phases, indicating that VSM is an effective treatment for improving and maintaining handwriting legibility in children with ASD. Results are discussed in terms of applicability of VSM as an intervention with academic skills deficits in children with ASD.     

Partisan Balance and Bias in Network Coverage of the 2000 and 2004 Presidential Elections

This study conceptualizes news bias as a causal factor producing systematic imbalance in the coverage of conflicting sides. Partisan bias is distinguished from structural bias by coverage that systematically favors one side with more prominence and attention. Content analysis was used to compare the television networks' balance in their treatment of Republican and Democratic candidates in stories and segments covering the 2000 and 2004 presidential elections. Presidential candidates received balanced aggregate treatment in both elections. But individual networks differed in their partisan balance. CBS News consistently favored the Democratic candidate in both elections, unlike the mixed results for ABC and NBC. CBS's pattern of imbalance, especially in the 2004 election, suggests a possible political bias in its coverage.     

A spectral analysis of team dynamics and tactics in Brazilian football

Abstract

The purposes of this study were to characterise the total space covered and the distances between players within teams over ten Brazilian First Division Championship matches. Filmed recordings, combined with a tracking system, were used to obtain the trajectories of the players (n = 277), before and after half-time. The team surface area (the area of the convex hull formed by the positions of the players) and spread (the Frobenius norm of the distance-between-player matrix) were calculated as functions of time. A Fast Fourier Transform (FFT) was applied to each time series. The median frequency was then calculated. The results of the surface area time series median frequencies for the first half (0.63 ± 0.10 cycles · min^?1) were significantly greater (P < 0.01) than the second-half values (0.47 ± 0.14 cycles · min^?1). Similarly, the spread variable median frequencies for the first half (0.60 ± 0.14 cycles · min^?1) were significantly greater (P < 0.01) than the second-half values (0.46 ± 0.16 cycles · min^?1). The median frequencies allowed the characterisation of the time series oscillations that represent the speed at which players distribute and then compact their team formation during a match. This analysis can provide insights that allow coaches to better control the team organisation on the pitch.
