Towards system oriented innovation policy evaluation? Evidence from EU28 member states

Many years after the introduction of the innovation system concept in innovation policy design, it is still not clear whether innovation policy evaluation practices follow a system approach. Building on evaluation and innovation studies, this article develops the concept ‘system oriented innovation policy evaluation’ based on four attributes (coverage, perspective, temporality and expertise). The attributes are used as analytical devices for gathering extensive empirical evidence on the actual practices of EU28 member states. The findings show that few countries have developed a type of innovation policy evaluation that is system oriented. The advent of a system approach to innovation policy evaluation offers the opportunity of comprehensive, contextualized and evidence-based innovation policy-making. However, there are still serious obstacles as such an approach requires important knowledge and organisational capacities. Overcoming these obstacles would need more decided evaluation capacity-building at the national level.     

Blending versus whole word approaches in first grade remedial reading: Short-term and delayed effects on reading and spelling words

Twelve very poor readers in May of first grade, including four withdisabilities, were randomly assigned to one of two daily tutoring conditions designed to teach children to read regularly spelled short words by one of two methods: blending sounds to form words, or cumulative introduction of whole words. Both treatments included letter/sound correspondences and spelling words in the reading set. At the end of ten sessions, no differences were found between the treatment outcomes; however, delayed posttests one week later found differences favoring the blending treatment on reading and spelling instructional words, and on transfer to words composed of known letter sounds.

Reference density trends in the major disciplines

The aim of this study was to determine whether different areas of knowledge presented different behaviour with regard to the number of references cited per journal document or if, conversely, they shared the same reference density practices. Bibliometric and bibliographic data were collected from 27,141 journals (indexed between 2001 and 2015 in the SCImago Journal & Country Rank (SJR)) and the growth rates in reference density and number of documents and journals in each category were calculated at different levels of aggregation.Our analysis identified that (a) mean reference density values in some Social Sciences and Arts and Humanities categories were equal to or higher than those in the “hard sciences”; (b) reference density growth rates in these disciplines were not as high as those in the hard sciences and, in general, did not correspond with growth rates in the number of documents produced; (c) this can be considered an indication that citation-based evaluation practices affect publication habits; and (d) no significant differences were found in mean values or growth rates between Gold Open Access and Non Gold Open Access journals.     

Benefits of achieving vigorous as well as moderate physical activity recommendations: evidence from heart rate complexity and cardiac vagal modulation

The aim of this study was to examine differences in traditional heart rate variability measurements and heart rate complexity (sample entropy) in young adults grouped by objectively measured achievement of either moderate or both moderate and vigorous physical activity recommendations. Of 168 young adults tested (86 females, 82 males; age 20.5 ± 1.2 years), 119 achieved only recommendations for moderate physical activity (moderate group) and 49 achieved recommendations for both moderate and vigorous physical activity (vigorous group). Analysis of covariance controlling for sex, weekly minutes of moderate physical activity, and percentage of body fat was used to assess between-group differences in heart rate variability and heart rate complexity. Logistic regression analysis was used to determine the group characteristics that best predicted high heart rate complexity and vagal indices of heart rate variability. The majority of the autonomic measures were higher (P < 0.05) in the vigorous group, and regression analysis showed that vigorous physical activity was the only multivariate predictor of higher heart rate complexity and higher heart rate variability. Young adults engaged in regular vigorous physical activity were more than twice as likely to have high heart rate complexity than those involved in predominantly moderate exercise. These findings suggest that vigorous physical activity is more closely associated with high heart rate complexity than moderate physical activity in young adults.     

Metabolic impact of a soccer match on female players

The aim of this study was to examine the metabolic effect of a female soccer match in elite and sub-elite teams. Blood samples were taken (24 h before, immediately after and 18 h after official soccer matches) to determine haematological, electrolytic and hormonal variables, as well as the levels of cell damage and oxidative stress in 14 elite and 14 sub-elite players. Our results show increases in white blood cell count (P < 0.001) and the percentage of neutrophils (P < 0.001), and decreases in the percentage of lymphocytes (P < 0.05), eosinophils (P < 0.001), monocytes (P < 0.001) and basophils (P < 0.05) immediately post-match. Increases were also found in lactate dehydrogenase activity (P < 0.001), uric acid (P < 0.001), albumin (P < 0.001), total antioxidant status (P < 0.001) and free testosterone levels (P < 0.01). Creatine kinase activity significantly increased 18 h post-match (P < 0.01) and the concentrations of several ions, glucose and proteins were found to be altered immediately post-match. Overall, our results show that playing a soccer match exerts specific metabolic effects on female players, resulting in muscle damage, oxidative stress and biochemical and hormonal variations. On the basis of some interesting correlations, we also suggest that exercise-induced cell breakdown may enhance antioxidant capacity of the soccer players.     

En Confianza: Co-constructing Professional Strength and Voice With Latina Early Childhood Educators

It is well documented in the literature that early pre-K reading experiences prepare children for the benefits of formal literacy instruction in the later grades. This is particularly true for young children from nonmainstream backgrounds. The objective of this article is to share the findings of a 4-year qualitative study investigating the relationships forged and teaching ideologies constructed by Latino pre-K teachers via critical “storying” within a culturally responsive professional learning community. Findings suggest that as teachers learned to recognize, listen to, and learn from the personal/professional individual and collective life histories of each other, their teaching efficacy was enhanced increasing their ability to develop effective literacy instruction that was culturally and linguistically responsive to the needs of young children.     

Tweeting but not Talking: The Missing Element in Talk Radio's Institutional Use of Twitter

The interplay between Twitter and media organizations has been an increasing area of research. This article examines how talk radio stations have adopted Twitter at an institutional level, based on a comparative study of the official accounts of three prominent talk radio stations in Canada in 2010 and 2011. While talk radio is considered an interpersonal medium, our analysis shows the stations mainly use Twitter as a one-way medium to broadcast news updates, rather than to engage with audiences. Our findings suggest a divergence between institutional and individual social media practices, with official accounts as formal channels of communication.
