Ranking dynamics and volatility

Scientific journals are ordered by their impact factor while countries, institutions or researchers can be ranked by their scientific production, impact or by other simple or composite indicators as in the case of university rankings. In this paper, the theoretical framework proposed in Criado, R., Garcia, E., Pedroche, F. & Romance, M. (2013). A new method for comparing rankings through complex networks: Model and analysis of competitiveness of major European soccer leagues. Chaos, 23, 043114 for football competitions is used as a starting point to define a general index describing the dynamics or its opposite, stability, of rankings. Some characteristics to study rankings, ranking dynamics measures and axioms for such indices are presented. Furthermore, the notion of volatility of elements in rankings is introduced. Our study includes rankings with ties, entrants and leavers. Finally, some worked out examples are shown.     

Interdisciplinary therapy changes superoxide dismutase activity and adiponectin in obese adolescents: a randomised controlled trial

The objective of this study is to evaluate the effect of interdisciplinary therapy in the parameters of the oxidative stress and the anti-inflammatory responses of obese adolescents. We selected 57 participants, who were randomly divided into 2 groups: interdisciplinary therapy group and a control group. After 6 months of intervention, 17 participants of the interdisciplinary therapy group and 8 of the control group returned for re-evaluation. The interdisciplinary therapy group participated in a treatment with 4 weekly sessions of exercise, a weekly group therapy session and a weekly nutritional education session. Blood parameters of oxidative stress and anti-inflammatory response were evaluated. The results demonstrated that there were significant increases in the interdisciplinary therapy group for superoxide dismutase activity (6.56 ± 3.22 to 11.40 ± 7.49) and ferric-reducing antioxidant potential concentration (532.91 ± 106.48 to 573.25 ± 112.57), although adiponectin levels did not reduce (40.9 ± 29.34 to 49.05 ± 41.22). A significant decrease in nitrite levels was also found (14.23 ± 8.48 to 11.45 ± 6.05). In the control group, significant reduction was found in adiponectin (31.56 ± 18.88 to 18.01 ± 11.66). This study suggests that interdisciplinary therapy for 6 months was effective in improving the anti-inflammatory responses and the antioxidant defences in obese adolescents.

Availability of Education and Training for Medical Specialists about the Impact of Dementia on Comorbid Disease Management

Individuals with dementia carry an additional health burden of multiple comorbid conditions. Effectively assessing and treating these comorbid conditions requires the medical specialist to be aware of, understand, and manage the effects of dementia on their clinical subspecialty practice. This ecological study describes the dementia-related education available to medical specialists in Australia outside the domains of geriatrics, neurology, and psychiatry. The dementia-related content of specialist medical training curricula and dementia-related information published in high-impact medical journals between 2000–2012 was reviewed. Dementia-related education was found to be absent from the training curricula for 14 of the medical specialties within Australia. And less than 0.10% (1,921 articles) of the more than two million articles published in the 138 journals assessed were dementia related.     

RELIGIOUS EDUCATION OF OLDER ADULTS: HISTORICAL PERSPECTIVES

This article presents a number of historical themes that are relevant to emerging efforts in the religious education of older adults. Drawing on themes in Jewish, Christian, Confucian, and other world religions the author indicates that religious bodies have shown respect for the elderly, especially for their abilities as teachers and counselors. Older adults have pursued learning either by living in close connection with religious communities or in separate institutions under the sponsorship of religious bodies. Religious traditions have urged study and contemplation as suitable activities for their older members. The increased numbers of older adults in religious bodies is a problem that can be turned into educational challenge and opportunity.     

Scenarios of quality assurance of stakeholder relationships in Finnish higher education institutions

Although the role and significance of the external stakeholders of higher education institutions has grown in recent years, quality assurance of stakeholder relationships remains a new phenomenon in the management practices of higher education institutions and in higher education research. Based on interviews and expert panel data, this article analyses the internal and external stakeholders’ perceptions of scenarios of the quality assurance of stakeholder relationships in Finnish higher education institutions. It especially focuses on exploring how institutions can balance internal and external stakeholders’ perspectives with regard to quality assurance. The results show that an essential challenge for Finnish higher education institutions is to develop flexible quality assurance practices capable of balancing the academic goals of the institutions and the needs of the external stakeholders. This also requires seeking balance between the centralised coordination and the differentiated practices of disciplines and academic units inside institutions.     

What's in a rating?

We examine the relationship between the formal ratings that principals give teachers and a variety of observable teacher characteristics, including proxies for productivity. Prior work has shown that principals can differentiate between more and less effective teachers, especially at the tails of the quality distribution, and that subjective evaluations of teachers are strongly correlated with subsequent student achievement. However, whereas prior work has relied on survey data, we consider formal ratings from a setting in which the stakes are reasonably high. We find that the ratings are correlated with an array of teacher qualities including experience for young teachers, education credentials, and teacher absenteeism. Our finding that principals reward qualities of teachers known to be related to student productivity provides reason to be optimistic about policies that would assign more weight to principal evaluations of teachers in career decisions and compensation.
