Broad strokes of recovery: the case of Croatia

For a long time after the proclamation of independence, Croatia suffered economic stagnation that negatively affected the development of science and higher education. However the turn of the millennium brought higher state investment in science and higher education, and all statistics now show a steady increase in the number of students and scientific personnel for the past several years. With these trends the focus has moved from the role the state can play in reviving science in Croatia to the necessity of greater participation in scientific funding, as well as the role that university graduates can play in the development of the country. The role of European integration and the brain drain phenomenon thus increase in importance, and this study provides some parameters for brain drain and the academic and intellectual labour market in Croatia.

Design thinking in pedagogy: Frameworks and uses

New learning approaches are now required to meet changing needs and develop appropriate skills and capabilities, often addressed as 21st century skills. In the last decade, design thinking has gained in popularity in higher education. This article describes the design thinking approach, its principles and models, various design thinking tools and their application in pedagogy. It presents the findings of an international study evaluating the creation and implementation of a culture‐based blended‐learning course for adult learners who are developing their 21st century skills by applying innovative teaching/learning methodologies, such as case studies, webquests and design thinking tools. Two hundred and twenty‐seven learners participated in the course and responded to a questionnaire to evaluate the learning platform, the English course developed, the teaching/learning methodologies applied and the development of their 21st century skills applying innovative learning tools. The findings highlight the benefits of the design thinking approach to skills development and point to the impact of the course content and layout and certain design thinking tools applied in developing 21st century skills.     

Use of evaluative devices by youth for sense-making of culturally diverse interpersonal interactions

Building upon recent research that defines psychological development as a continuous process of sense-making situated within a cultural and historical context, this paper explores how culturally diverse youth growing up in New York City use evaluative language to enact relational complexity as they make sense of technologically mediated interpersonal interactions with their peers. Forty-four individuals (ages 15–20) participated in a quasi-experimental research workshop that engaged them in the process of sense-making by asking them to write projective narratives toward a vignette depicting text-massage mediated interpersonal interaction embedded among monocultural and bicultural group of peers. Data analyses focus on evaluative devices used by youth and manifest the relational flexibility of sense-making by immigrant youth and their U.S. born peers across diverse relational dimensions. Results suggest that immigrant youth are able to coordinate diverse ways of interpreting interpersonal interactions across relational dimensions, manifest by varied use of logical/hypothetical, causal and affective evaluative devices. In contrast U.S. born youth largely use same frequency of evaluative devices across two relational dimensions. Statistical analysis highlights the use of affect in projective narratives by exploring a discursive learning hypothesis: that higher use of emotions in the process of sense-making by U.S. born youth gradually scaffolds the use of emotions in narrative by immigrant youth.     

Diagnostic accuracy of heart fatty acid binding protein (H-FABP) and glycogen phosphorylase isoenzyme BB (GPBB) in diagnosis of acute myocardial infarction in patients with acute coronary syndrome

Introduction:

This study aimed to assess whether heart fatty acid-binding protein (H-FABP) and glycogen phosphorylase isoenzyme BB (GPBB) could be used for the accurate diagnosis of acute myocardial infarction (AMI) in acute coronary syndrome (ACS) patients.

Materials and methods:

The study included 108 ACS patients admitted to a coronary unit within 3 h after chest pain onset. AMI was distinguished from unstable angina (UA) using a classical cardiac troponin I (cTnI) assay. H-FABP and GPBB were measured by ELISA on admission (0 h) and at 3, 6, 12, and 24 h after admission; their accuracy to diagnose AMI was assessed using statistical methods.

Results:

From 92 patients with ACS; 71 had AMI. H-FABP and GPBB had higher peak value after 3 h from admission than cTnI (P = 0.001). Both markers normalized at 24 h. The area under the receiver operating characteristic curves was significantly greater for both markers in AMI patients than in UA patients at all time points tested, including admission (P < 0.001). At admission, the H-FABP (37%) and GPBB (40%) sensitivities were relatively low. They increased at 3 and 6 h after admission for both markers and decreased again after 24 h. It was 40% for H-FABP and approximately 2-times lower for GPBB (P < 0.01). In AMI patients, both biomarkers had similar specificities, positive- and negative-predictive values, positive and negative likelihood ratios, and risk ratios for AIM.

Conclusion:

H-FABP and GPBB can contribute to early AMI diagnosis and can distinguish AMI from UA.     

Convexity in scientific collaboration networks

Convexity in a network (graph) has been recently defined as a property of each of its subgraphs to include all shortest paths between the nodes of that subgraph. It can be measured on the scale [0, 1] with 1 being assigned to fully convex networks. The largest convex component of a graph that emerges after the removal of the least number of edges is called a convex skeleton. It is basically a tree of cliques, which has been shown to have many interesting features. In this article the notions of convexity and convex skeletons in the context of scientific collaboration networks are discussed. More specifically, we analyze the co-authorship networks of Slovenian researchers in computer science, physics, sociology, mathematics, and economics and extract convex skeletons from them. We then compare these convex skeletons with the residual graphs (remainders) in terms of collaboration frequency distributions by various parameters such as the publication year and type, co-authors’ birth year, status, gender, discipline, etc. We also show the top-ranked scientists by four basic centrality measures as calculated on the original networks and their skeletons and conclude that convex skeletons may help detect influential scholars that are hardly identifiable in the original collaboration network. As their inherent feature, convex skeletons retain the properties of collaboration networks. These include high-level structural properties but also the fact that the same authors are highlighted by centrality measures. Moreover, the most important ties and thus the most important collaborations are retained in the skeletons.     

Validation of a Tennis Rating Score to evaluate the technical level of children tennis players

The purpose of this study was to create a valid and reliable assessment scale for the evaluation of three basic tennis strokes (forehand, backhand, serve) for 6–12-year-old tennis players, named the Tennis Rating Score for Children (TRSC). Altogether 60 players (21: forehand, 22: backhand, 17: serve) were video recorded (30 frames per second) while performing three main tennis strokes and later evaluated using the TRSC by five tennis trainers at Day 1 and Day 7. Agreement between days and raters was examined using the intraclass correlation coefficients (ICC). A Pearson’s correlation was calculated to determine convergent validity (score related to participant’s level of experience). The reliability between raters was very high for all three main strokes (ICC_FOREHAND = 0.874; ICC_BACKHAND = 0.877; ICC_SERVE = 0.877). The intra-rater test-retests ICCs were also very high (ICC_FOREHAND = 0.885; ICC_BACKHAND = 0.891; ICC_SERVE = 0.887). A large (r_FOREHAND = 0.660) and very large (r_BACKHAND = 0.730; r_SERVE = 0.772) Pearson’s correlations were found between all the ratings and the level of experience. The TRSC is shown to be highly reliable and valid when assessing technical skills in novice players, when compared to actual assessment from coaching experts; this tool may be helpful for tennis coaches to make a more objective diagnostic of the technical level of young tennis players.     

Immediations and rhythms of speculative design: Implications for value in design-based research

This paper presents data from the first six-months of an ongoing speculative design project in which youth and researchers co-created a videogame club, and later an eSports team, in an urban youth centre in Montréal, Québec. It describes how process philosophy informed researchers’ approach to speculative design, allowing youth and researchers to co-compose a sense of value for the club and the potentials for what they could do together through the club. This speculative process is contrasted with structuralist approaches to design-based research in education, which can overly or pre-determine value and mechanisms of social change, with or without the collaboration of youth and communities.
