Charity and public libraries: Does government funding crowd out donations?

This paper analyzes the determinants of donations to public libraries testing the following hypothesis: Is there a crowd out effect from government funding of public libraries? I look at novel data, the Public Library Survey, and use an unbalanced panel of public libraries across the USA from 2000 to 2013. The results suggest a crowd in effect with an inverted U shape in all levels of government. Local government is associated with 4–6 cents increase in donations, state government with 20–23 cents increase, and federal government with 75 cents to 1 dollar and 33 cents.     

Resitting or compensating a failed examination: does it affect subsequent results?

Institutions of higher education commonly employ a conjunctive standard setting strategy, which requires students to resit failed examinations until they pass all tests. An alternative strategy allows students to compensate a failing grade with other test results. This paper uses regression discontinuity design to compare the effect of first-year resits and compensations on second-year study results. We select students with a similar level of knowledge in a first-year introductory course and estimate the treatment effect of a resit on the result for a second-year intermediate course in the same subject. We find that the treatment effect is positive, but insignificantly different from zero. Additional results show that students’ overall second-year performance is insignificantly related to the number of compensated failing grades in their first year. The number of attempts that students need to complete their first year does not have a significant positive effect on second-year performance. We conclude that the evidence for a positive effect of resits on learning is weak at best.     

Further thoughts on the writing of stories: a response to Michael Gard and Ian Wellard

The terminological disunity in the usage of the terms 'sport' and 'physical culture' leads to controversy over their meanings. This study recapitulates their content (substance) in a broader sense than is usual in common usage and points out some possible philosophical connections. The first part focuses on an analysis of the terms: 'culture' and 'body' and their joining together to form the term 'physical culture'. The author first calls attention to other levels of human corporeality than sport and movement (such as hygiene, body aesthetics, eroticism, etc.), which show us that the implications of the term 'physical culture' is too broad. On the other hand, the term 'sport' is delimitated too narrowly, because the cultivation of human motion is a concern in school physical education and recreational physical exercise as well. The second part gives reasons for the use of the term 'kinanthropology' and allows us to grasp its philosophical conception as 'philosophical kinanthropology'.     

Wege in die Wissenschaft

Zusammenfassung Dieser Artikel besch?ftigt sich mit einem Themengebiet, das in der erziehungswissenschaftlichen Wissenschafts-, Hochschul-und Berufsforschung bislang kaum analysiert worden ist. Unter Bezug auf die Ergebnisse einer schriftlichen Befragung von rund 3.800 Absolventen erziehungswissenschaftlicher Hauptfachstudieng?nge (Diplom, Magister) in ganz Deutschland wird die Frage untersucht, wie gro? die Gruppe der Studierenden aus diesen Studieng?ngen ist, die sich einige Jahre nach dem Studienabschluss im Arbeitsfeld Hochschule und Forschung beruflich platzieren kann bzw. promoviert, durch welche Merkmale diese Gruppe gekennzeichnet ist und welche Bedingungsfaktoren den Weg in die Wissenschaft beeinflussen. Nach einem überblick über den bisherigen Stand der Forschung und der Darstellung zentraler Resultate des Diplom-und Magister-Surveys zum Weg in die Wissenschaft werden abschlie?end einige Konsequenzen diskutiert, die sich aus den Befunden für eine Reform der bisherigen Hauptfachstudieng?nge bzw. für die zukünftige Gestaltung neuer Studieng?nge mit Blick auf eine Verbesserung der Nachwuchsf?rderung für das Fach Erziehungswissenschaft ergeben.

Summary Paths into Science: The Results of a National Survey of Graduates from Diplom and Magister Programs in Educational Science This article examines a topic which has hardly been dealt with in the field of Educational Science. A survey of around 3,800 graduates of Educational Science in both Diplom and Magister programs in Germany asked what proportion of graduates went on to work or commence a Ph.D. in higher education. It also investigated the characteristics of such graduates and the conditions which determined their path into science. Following an overview of preceding research in this area and a presentation of the central results of the survey, the consequences of the findings for a reform of courses and an improvement in the training of academics in the field of Educational Science will be discussed.

     

The research and evaluation of serious games: Toward a comprehensive methodology

The authors present the methodological background to and underlying research design of an ongoing research project on the scientific evaluation of serious games and/or computer‐based simulation games (SGs) for advanced learning. The main research questions are: (1) what are the requirements and design principles for a comprehensive social scientific methodology for the evaluation of SGs?; (2) to what extent do SGs contribute to advanced learning?; (3) what factors contribute to or determine this learning?; and (4) to what extent and under what conditions can SG‐based learning be transferred to the real world? In the Netherlands between 2005 and 2012, several hundred SG sessions with 12 SGs were evaluated systematically, uniformly and quantitatively to create a dataset, which comprises data on 2488 respondents in higher education or work organizations. The authors present the research model, the quasi‐experimental design and the evaluation instruments. This focus in this paper is on the methodology and dataset, which form a sound foundation for forthcoming publications on the empirical results.     

Does a resistance exercise session with continuous or intermittent blood flow restriction promote muscle damage and increase oxidative stress?

The aim of this study was to compare the effect of low-load resistance exercise (LLRE) with continuous and intermittent blood flow restriction (BFR) on the creatine kinase (CK), lactate dehydrogenase (LDH), protein carbonyl (PC), thiobarbituric acid-reactive substance (TBARS) and uric acid (UA) levels in military men. The study included 10 recreationally trained men aged 19 ± 0.82 years who underwent the following experimental protocols in random order on separate days (72–96 h): 4 LLRE sessions at a 20% 1RM (one-repetition maximum [1RM]) with continuous BFR (LLRE + CBFR); 4 LLRE sessions at 20% 1RM with intermittent BFR (LLRE + IBFR) and 4 high-intensity resistance exercise (HIRE) sessions at 80% 1RM. The CK and LDH (markers of muscle damage) levels were measured before exercise (BE), 24 h post-exercise and 48 h post-exercise, and the PC, TBARS and UA (markers of oxidative stress) levels were measured BE and immediately after each exercise session. There was a significant increase in CK in the HIRE 24 post-exercise samples compared with the LLRE + CBFR and LLRE + IBFR (P = 0.035, P = 0.036, respectively), as well as between HIRE 48 post-exercise and LLRE + CBFR (P = 0.049). Additionally, there was a significant increase in CK in the LLRE + CBFR samples BE and immediately after each exercise (Δ = 21.9%) and in the HIRE samples BE and immediately after each exercise, BE and 24 post-exercise, and BE and 48 post-exercise (Δ values of 35%, 177.6%, and 177.6%, respectively). However, there were no significant changes in LDH, PC, TBARS, and UA between the protocols (P > 0.05). Therefore, a physical exercise session with continuous or intermittent BFR did not promote muscle damage; moreover, neither protocol seemed to affect the oxidative stress markers.     

A microfluidics assisted porous silicon array for optical label-free biochemical sensing

A porous silicon (PSi) based microarray has been integrated with a microfluidic system, as a proof of concept device for the optical monitoring of selective label-free DNA-DNA interaction. A 4 × 4 square matrix of PSi one dimensional photonic crystals, each one of 200 μm diameter and spaced by 600 μm, has been sealed by a polydimethylsiloxane (PDMS) channels circuit. The PSi optical microarray elements have been functionalized by DNA single strands after sealing: the microfluidic circuit allows to reduce significantly the biologicals and chemicals consumption, and also the incubation time with respect to a not integrated device. Theoretical calculations, based on finite element method, taking into account molecular interactions, are in good agreement with the experimental results, and the developed numerical model can be used for device optimization. The functionalization process and the interaction between DNA probe and target has been monitored by spectroscopic reflectometry for each PSi element in the microchannels.     

Migratory plans of Portuguese adolescents

A substantial proportion of northern Portuguese adolescents belonging to lower and middle socioeconomic levels plan to eventually migrate abroad. Migratory plans therefore join academic and career plans in forming adolescents' overall personal plans. This paper considers motivations, awareness, and characteristics of 511 8th graders living in Oporto and the Braganca area who stated their intentions to migrate. The intention to migrate proved especially significant in the personal plans of youths from rural areas and of low socioeconomic status. In proportions comparable to that found among migrant workers, unemployment, low pay, and thwarted aspirations fueled the desire to migrate. The percentage of youths firmly committed to relocating increased with age, while overall increased desire to emigrate has been linked to rising domestic unemployment. Respondents were also largely aware of the potential physical, emotional, and psychological problems of living and working abroad. Migration plans were found to directly interfere with students' academic and careers plans. Those planning to migrate were less likely to consider further education and engagement in highly skilled occupations.
