The methodological benefits of social media: “studying up” in Brazil in the Facebook age

While conducting research on the organizational cultures of elite nonprofit organizations in Rio de Janeiro, the author encountered many access issues identified in the current literature: in particular, difficulty in encountering research subjects due to the transitional nature of educational nonprofits and the role of secretaries and administrators as gatekeepers. This article explores two previously undeveloped methodological innovations utilized by the author to overcome these difficulties with regard to access: namely, the use of social media as a participant recruitment tool and the use of an organization's online marketing presence as an alternative data source.     

The construction of a transnational Lusophone media space: A historiographic analysis

This piece examines the historical construction of a Lusophone cultural-linguistic media space and market that spans portions of Europe, Africa, and South America. Beginning with the Portuguese colonization of Brazil and Lusophone Africa in the 17th century and continuing to the contemporary moment, our discussion examines how a combination of political, ideological, and economic patterns created linkages between Portugal, Brazil, and Portuguese-speaking colonies in Africa (namely Angola, Cape Verde, and Mozambique). After examining how Brazil grew to become the dominant cultural producer in this transnational matrix (most explicitly expressed through the massive exports of telenovelas and music since the late 1970s), we examine how other countries are beginning to carve out distinctive national niches, including the contemporary music scene in Cape Verde and the rise of domestically produced telenovelas in Portugal and Angola that are increasing in circulation in the contemporary transnational Lusophone media space.     

Psychometric analysis of a measure of socio-emotional development in adolescents

This is a psychometric analysis of an instrument to assess the socio-emotional development of school students, How I Feel (HIF), developed as a situational judgment test, with scoring based on expert judgments. The HIF test was administered in grades 4–9, 1999–2005. Internal consistency, retest reliability, and year-to-year stability were satisfactory, and the HIF instrument appears sensitive to intervention effects. Sex differences and associations with substance use and other instruments support construct validity. A significant negative trend was found across grades, attenuated in a group receiving socio-emotional training. The HIF test has limited discriminatory power among individuals with high socio-emotional maturity.     

National Assessment of Writing Proficiency Among Norwegian Students in Compulsory Schools

The paper reports and discusses a government‐initiated nationwide assessment of writing proficiency among Norwegian compulsory school students. A sample‐study of 7th and 10th grade students are discussed and reported with regard to challenges in measuring writing skills in a valid and reliable manner. For the 7th graders the results showed a greater proportion of narrative texts, and in contrast to more scientific oriented texts, was assessed as “lower than expected”; however, for the 10th graders the tendency was opposite with respect to central linguistic components. Low correlations between the raters were ascertained at both levels, indicating different views among teachers as to what can be expected of students' writing proficiency. The results are discussed in relation to the usefulness of the theoretical model as a basis for assessment of writing proficiency, as well as other obstacles to constructing valid and reliable writing tests.     

Distance education for dentists: Improving the quality of online instruction

Abstract

This study describes the development and the evaluation of quality assurance criteria for online dental education. These criteria were developed by the authors and evaluated by oral health professionals through an Internet survey. The survey indicated that oral health professionals ranked the creation of scientifically based, frequently updated courses that clearly define their educational goals and objectives as highly important.     

Introducing quantum mechanics in the upper secondary school: A study in Norway

The study reported in this paper is a survey (n=236) that examines how upper secondary students (18-19 years old) in Norway come to terms with the wave-particle duality as presented as part of a short introduction to quantum physics. The main conclusion is that this concept is poorly understood. Some students demonstrate clear and explicitly formulated misconceptions rooted in a classical physics world-view. Scholars in physics have stated that the concept of duality is unnecessary, but still included in school and university physics. It is argued that school physics should give a more explicit focus to the challenge that quantum physics presents to the classical worldview, thus introducing the importance of an affective dimension in the learning and teaching of quantum physics. This study replicates evidence from other studies that wave-particle duality does not introduce such a challenge.     

Literature Awareness Among Health Staff in Developing Countries

Abstract

Health professionals, although in principle a highly information-conscious group, are frequently observed to be poor users of literature and library services. The main reason for this lack of literature awareness is the tradition of oral transmission of knowledge found in a number of Third World countries. Since the practice of modern medicine is not conceivable without constant support from the professional literature, either for reference or continuing education purposes, it is suggested that national or regional programmes be launched to promote literature awareness, notably among medical and nursing students. This requires the active participation of faculty staff as well as policy and financial commitments of the governments concerned. Failure to heighten the literature awareness of coming generations of physicians and nurses, and in general to improve the situation in the sector of health information support could have serious consequences on the quality of medical care in large parts of the developing world.     

High-speed observations of football-boot-surface interactions of players in their natural environment

A protocol has been developed to obtain two-dimensional kinematic shoe data of football players in their training environment through high-speed video analysis. Such kinematic data can provide an understanding of how to better replicate the boundary conditions of football movements when simulated using mechanical traction and penetration test devices. As part of a pilot study, 11 youth academy players from a Premiership football club performed football-specific movements which were filmed at 1000 frames s^-1. The protocol required minimal set-up time and the area of the pitch to be filmed could be positioned in any part of the playing area, causing low disruption to the players. This aimed to ensure that the movements performed were representative of those carried out during competitive play. Results in this study are concerned with the kinematics of the shoe during contact with the ground for movements identified to be important in terms of injury risk and loss of performance (slipping). Shoe velocities and orientations were measured for subjects wearing shoes of different stud types (traditional round studs versus contemporary bladed studs) on two surfaces (artificial turf, in-filled with rubber and sand, versus a natural surface). All the parameters measured from the relatively small population of subjects had high variances and therefore few significant effects of studs and surface could be found. The data does however provide insight into the appropriate boundary conditions to be used in mechanical test devices. For example, in the forefoot push-off movement it can be seen that test devices should measure the traction forces when the shoe first starts to move, as this is when the player would lose performance, as opposed to the maximum traction which can occur after significant displacement of the shoe through the surface. Analysis of the orientation and velocity path of the studs just before contact with the ground shows that the studs could be aligned to enhance their penetration into the surface and optimise the traction properties of the studs. In order to determine the orientation and velocity of the shoes at crucial phases in movements force-plate data obtained in the laboratory should be utilised in future studies.
