Managing the complexity of centres of excellence: accommodating diversity in institutional logics

This article discusses how Centres of Excellence (CoE) and the existence of several logics in these centres can contribute to the differentiation of the strategic profiles of universities. The study sees research centres as a way to organize research activities in Higher Education Institutions (HEIs) in order to target both excellence but also societal challenges through focused thematic research. It reveals how societal challenges and their interpretation by these centres contribute to the differentiation of the strategic profiles of universities. Studies of centres of excellence programs in Sweden and Japan reveal differences in how their mission is formulated for relevance and excellence. The results indicate that contrasting missions of HEIs are accommodated through the dual logics of these centres relating both to autonomy and industry collaboration. The study shows that long-term funding gives these centres flexibility to set the agenda and focus on their strategic core activities. In other words, a logic of autonomy guides their strategic choices of research activities over the long-run as well as collaborators. Nevertheless, these centres are also developing strategies to cope with dilemmas stemming from the excellence-relevance and evaluation templates that emerge in the nexus of their collaborative ties with industry, government and universities.

     

Can narrative cutscenes improve home learning from a math game? An experimental study with children

Little is known about the instructional effects of narrative framing elements in child learning games. In this study, second and third graders (M_age = 8.24) played one of two versions of a successful, commercial mathematical learning game at home for 2 weeks (N = 95; between-subject design). The versions differed in the presence/absence of a background story conveyed through comic cutscenes at the beginning and the end of the game. Results showed that children played the game intensively in both conditions: despite not being forced to do so. Plus, they also learned from the game. As expected, children assigned to the cutscenes condition interfaced with the cutscenes. However, no between-group difference was detected in pre-post learning gains, parent-reported engagement, self-reported enjoyment, time spent with the game and the number of solved in-game tasks (all |ds| < 0.29). Altogether, no advantage or disadvantage from the narrative comic cutscenes was revealed.     

Investigating the effects of multimedia input modality on L2 listening skills of Turkish EFL learners

The present study examined whether or not different input delivery modes have an effect on listening comprehension of Turkish students learning English at the university level. It investigated the effect of one single mode, which is audio-only, and three dual input delivery modes, which were audio-video, audio-video with target language subtitles and audio with PowerPoint presentation, on listening comprehension. The data have been gathered through: a listening proficiency exam, a topic familiarity questionnaire, listening comprehension tests, think-aloud protocols and a semi-structured focus group interview. Analysis of data demonstrated that the students’ listening comprehension scores were significantly lower in audio-video with subtitles mode. In addition to this, the students stated that they experienced most confusion and anxiety in understanding through audio-video with subtitles. Moreover, the students mentioned that they were most successful in the audio with PowerPoint presentation mode. Results also indicated that the students were influenced by their pre-university listening class experiences, meaning that they were most accustomed to the audio-only mode, and therefore felt most relaxed when they listened only.     

Challenges in developing the academic profession in the Western Balkans

In this paper, we explore the developmental challenges facing the academic profession in Europe and especially in some Western Balkan countries, Croatia and Slovenia. First, we look at how the higher education environment determines key changes to the academic profession: expectations to demonstrate professional expertise, internationalisation, segmentation, and precarity. While these processes are mainly considered from the above perspective, we also examine the work of academics from within. Second, we discuss aspects of academic tasks, challenges of synchronising academic work with performance measures, intensification of work and expansion of bureaucratic tasks. Building on these perspectives, we introduce a qualitative pilot study that tests how these general trends described in the literature may be applied to given situations in five countries of former Yugoslavia: Slovenia, Croatia, Serbia, North Macedonia and Kosovo. Although these countries cover a relatively small geographical area, the differences among them with respect to the economy, society and politics are important. Our findings suggest that problems accumulating in academic work in Slovenia and Croatia were in almost all of the surveyed aspects less problematic than in the three other observed countries.     

Do elementary school‐based child abuse prevention programs work? A high school follow‐up

Despite the widespread use of school‐based abuse prevention programs, few studies support their effectiveness in helping children avoid victimization. Most studies that evaluate prevention programs measure changes in children's knowledge and not subsequent behavior. Further, the link between knowledge, behavior, and the ability to avoid or reduce victimization has not been established. In this study the impact of a school‐based prevention program was assessed by surveying students at a high school in southern California where students from feeder elementary and junior high schools were known to have had abuse prevention programs available to them. Data were collected anonymously on 137 high school students during their Health class. A quasi‐experimental design was utilized, comparing the 72 students who had attended one or more school‐based abuse prevention program with the 65 who stated they had not participated in a prevention program. Demographic similarities between the two groups were established. Students who attended prevention programs were more knowledgeable about abuse concepts and reported fewer incidents of abuse. However, the effectiveness of students' responses to abuse, even when they were using strategies taught by the prevention programs, was variable. Questions about the effectiveness of these strategies with familial and nonfamilial abuse are discussed. © 2001 John Wiley & Sons, Inc.     

MATHEMATICS TEACHERS’ CONCEPTIONS OF PROOF: IMPLICATIONS FOR EDUCATIONAL RESEARCH

Current mathematics education reforms devoted to reasoning and proof highlight its importance in pre-kindergarten through grade 12. In order to provide students with opportunities to experience and understand proof, mathematics teachers must have a solid understanding of proofs themselves. In light of this challenge, a growing number of researchers around the world have started to investigate mathematics teachers’ conceptions of proof; however, much more needs to be done. Drawing on lessons learned from research and curricular recommendations from around the world, the main purpose of this paper is to review the literature on elementary and secondary mathematics teachers’ conceptions of proof and discuss international implications.     

Reliability and Validity of Finger Strength and Endurance Measurements in Rock Climbing

Purpose: An advanced system for the assessment of climbing-specific performance was developed and used to: (a) investigate the effect of arm fixation (AF) on construct validity evidence and reliability of climbing-specific finger-strength measurement; (b) assess reliability of finger-strength and endurance measurements; and (c) evaluate the relationship between finger flexor all-out test scores and climbing ability. Methods: To determine the effect of AF, 22 male climbers performed 2 maximal strength and all-out tests with AF (shoulder and elbow flexed at 90°) and without AF (shoulder flexed at 180° and elbow fully extended). To determine reliability, 9 male climbers completed 2 maximal strength tests with and without AF and an all-out and intermittent test without AF. Results: The maximal strength test without AF more strongly determined climbing ability than the test with AF (r² = .48 and r² = .42 for sport climbing; r² = .66 and r² = .42 for bouldering, respectively). Force and time variables were highly reliable; the rate of force development and fatigue index had moderate and low reliability. The maximal strength test with AF provided slightly higher reliability than without AF (intraclass correlation coefficient [ICC] = 0.94, ICC = 0.88, respectively). However, smaller maximal forces were achieved during AF (484 ± 112 N) than without AF (546 ± 132 N). All-out test average force had sufficiently high reliability (ICC = 0.92) and a relationship to sport climbing (r² = .42) and bouldering ability (r² = .58). Conclusion: Finger strength and endurance measurements provided sufficient construct validity evidence and high reliability for time and force parameters. Arm fixation provides more reliable results; however, the position without AF is recommended as it is more related to climbing ability.     

The effects of transport by pneumatic tube system on blood cell count,erythrocyte sedimentation and coagulation tests

Introduction:

Today, the pneumatic tube transport system (PTS) is used frequently because of its advantages related to timing and speed. However, the impact of various types of PTS on blood components is unknown. The aim of this study was to examine the influence of PTS on the quality of routine blood cell counts, erythrocyte sedimentation, and certain blood coagulation tests.

Materials and methods:

Paired blood samples were obtained from each of 45 human volunteers and evaluated by blood cell count, erythrocyte sedimentation, and several coagulation tests, including prothrombin time (PT) and activated partial thromboplastin time (aPTT). Blood samples were divided into 2 groups: Samples from group 1 were transported to the laboratory via the PTS, and samples from group 2 were transported to the laboratory manually. Both groups were evaluated immediately by the tests listed above.

Results:

The blood sample test results from groups 1 and 2 were evaluated and compared. No statistically significant differences were observed (P = 0.069–0.977).

Conclusion:

The PTS yielded no observable effects on blood cell counts, erythrocyte sedimentation, or PT and aPTT test results. We concluded that the PTS can be used to transport blood samples and yield reliable results for blood cell counts, erythrocyte sedimentation, and several coagulation tests.     

Skeleton Changes Induced by Horse Riding on Medieval Skeletal Remains from Croatia

Skeletal remains of 35 individuals from the Croatian excavation site Kamen Most – Kaldrma from the fourteenth to fifteenth centuries were analyzed anthropologically. Due to specific skeletal characteristics, eight of them were analyzed in great detail in this study. The results of additional analysis indicated that all bone elements, except pelves, of all eight persons belonged to males. All pelvic girdle have characteristics of female sex and pronounced muscle attachments that are both indicative of horse riding. All eight persons had at least two of six changes on femora indicative of horse riding. Vertebrae of seven persons (one person did not have preserved vertebrae) have Schmorl's nodes. Signs of advanced osteoarthritis were found on all joints in all eight persons. All of them also have visible signs of periostitis especially on lower extremities. Pathological signs of trauma were found in five persons. Two of them had skull fractures and the rest had fractures of extremities which are also characteristic for horse riders. The average age of all eight persons was above 45 years at death. DNA analysis confirmed male sex for seven individuals. The results were additionally confirmed by later archeological findings of tombstones with illustrations of horse riders.
