The primary objective of this study was to compare a sample ofprison inmates with the norms obtained for large samples of 12year-old students on tests measuring word decoding skills,reading and spelling abilities. Theoretically, we assumed thatphonological processing deficits are a strong predictor ofdyslexic problems, and thus, only those inmates who did not seemto possess appropriate levels of phonological decoding skillsshould be defined as dyslexics. The results showed that theinmates performed better or at the same level as 12 year-oldstudents on all tasks measuring reading, spelling, and worddecoding skills, and that 4 out of 35 inmates (11%) with Swedishas their native language exhibited phonological decoding skillssubstantially below the average of grade 6 students. Thus, bycomparing the group of inmates with 12 year-old students, and byusing phonological decoding skills as an indicator of reading andwriting disabilities, our conclusion was that the frequency ofpossible dyslexic problems found in a group of prison inmateslooks very much like comparable incidence figures from a generalpopulation.  相似文献   

Promoting schoolchildren’s self-esteem in physical education: testing the effectiveness of a five-month teacher training

ABSTRACT

Background: Schoolchildren’s personality development is considered a central goal of physical education (PE). With regard to the relationship between psychological well-being and global self-esteem over the life course, the promotion of positive self-esteem is an issue of particular significance. Past research revealed that PE taught with an individualized teacher frame of reference (iTFR) and a reflexive teaching style is associated with positive effects on facets of children’s perceived sports competence. However, it remains an open question whether this teaching styles has the potential to promote positive self-esteem.

Purpose: The present study investigated whether a five-month teacher training, aimed to enhance the teachers’ iTFR and their reflexive teaching style in PE, has a positive effect on students’ perceived sports competence and their global self-esteem. To analyse the implementation quality, changes in students’ perceived iTFR and perceived reflexive teaching style were investigated.

Method: A total of 21 teachers were assigned to either an intervention group (n?=?13), receiving the five-month teacher training, or a control group (n?=?8) consisting of regular teaching without teacher training. The teacher training encompassed five three-hour consecutive sessions during which the teachers acquired theoretical and practical knowledge about the promotion of competence perceptions in PE with a reflexive teaching style and an iTFR. Between the sessions, the teachers were instructed to implement an iTFR and a reflexive teaching style into their own PE classes. To evaluate the effects of the teacher training, their students’ (N?=?315, 53.7% girls, M_age?=?13.2 y, SD_age?=?1.3 y) perceived teaching style (iTFR and reflexive teaching), perceived sports competence and global self-esteem were measured with paper-pencil questionnaires at three measurement points (pre, post and follow-up).

Findings: Linear mixed effect models showed that students of the intervention group reported an increase in their teachers’ reflexive teaching style, but there were no changes with regard to iTFR. With regard to students’ perceived sports competence and global self-esteem, there were significant interaction effects between time and group over a period of eight months (from pre-test to follow-up), indicating positive effects on these self-concept dimensions due to the teacher training.

Conclusion: The present study indicates that a long-term teacher training supports PE teachers to implement teaching styles with the aim to promote students’ self-concept. Furthermore, the findings lead to the assumption that a more pronounced iTFR in combination with an enhanced reflexive teaching style has the potential to positively influence schoolchildren’s perceived sports competence and global self-esteem.  相似文献   

The Subsidized Muse: Government and the Arts in Western Europe and the United States     

Annette Zimmer  Stefan Toepler 《Journal of Cultural Economics》1999,23(1-2):33-49

Using the neo-classical justifications for government support of the arts that Dick Netzer discussed in The Subsidized Muse as a starting point, the article contends that market failure is not an useful concept to understand and explain cultural policies and the degree of government involvement, particularly when viewed from a comparative perspective. The basic fault is that historical- institutional arrangements and the role of non-state actors in the formation of cultural policies are not taken into account. Discussing some aspects of the institutional framework in the development of French, Swedish and U.S. cultural policies, the article concludes with a call for the use of neo-institutionalist perspectives in analyzing government intervention in the arts field.  相似文献

The Cost-effectiveness of Preventive Conservation Actions     

Stefan Michalski  Irene Karsten 《文物保护研究》2018,63(5):187-194

ABSTRACT

Two historic house museums, a municipal art gallery, and a provincial archive have had comprehensive risk and option assessments done by the Canadian Conservation Institute. For each institution, an average of 60 options addressing 40 risks was analyzed in terms of risk reduction, cost, and cost-effectiveness. A meta-analysis found that cost-effectiveness follows a strong economy of scale within each institution. By estimating valuation of each collection, cost-effectiveness was converted into benefit–cost ratio of dollar spent per dollar value saved and was found not to follow an economy of scale between small and large institutions. Optimization software was applied to see if precise maximization of risk reduction gave significantly different recommendations than those in the original reports which relied on the Pareto rule of addressing the largest risks first.  相似文献

Ultrasonic phased array technology for the non-destructive testing of marble sculptures     

Frank Tiefensee  Peter Weber  Simon Kunz  Marisa Pamplona  Stefan Simon 《文物保护研究》2017,62(1):55-60

The medical ultrasonic phased array technology was modified for the non-destructive testing of marble sculptures and the feasibility of the approach was evaluated. For this purpose, 1?MHz, 64-channel phased array electronic and phased array transducers were developed. The specifications of the electronics and the transducers are presented and discussed. Ultrasound images of inner structures of a marble sculpture are presented. The problem of the acoustic matching layers for different states of deterioration is discussed and the developments in view of a suitable matching layer solution are presented. This matching layer is combined with a new coupling technique that protects the marble surface. The results of experiments on ultrasound phantoms and on a marble sculpture are presented.  相似文献   

Hybrid index maintenance for contiguous inverted lists     

Stefan Büttcher  Charles L. A. Clarke 《Information Retrieval》2008,11(3):175-207

Index maintenance strategies employed by dynamic text retrieval systems based on inverted files can be divided into two categories: merge-based and in-place update strategies. Within each category, individual update policies can be distinguished based on whether they store their on-disk posting lists in a contiguous or in a discontiguous fashion. Contiguous inverted lists, in general, lead to higher query performance, by minimizing the disk seek overhead at query time, while discontiguous inverted lists lead to higher update performance, requiring less effort during index maintenance operations. In this paper, we focus on retrieval systems with high query load, where the on-disk posting lists have to be stored in a contiguous fashion at all times. We discuss a combination of re-merge and in-place index update, called Hybrid Immediate Merge. The method performs strictly better than the re-merge baseline policy used in our experiments, as it leads to the same query performance, but substantially better update performance. The actual time savings achievable depend on the size of the text collection being indexed; a larger collection results in greater savings. In our experiments, variations of Hybrid Immediate Merge were able to reduce the total index update overhead by up to 73% compared to the re-merge baseline.

Regulating film,regulating emotion: the emotional history of public opinion     

Jennifer Petersen 《Critical Studies in Media Communication》2016,33(4):324-336

The article argues that the legal about face in 1950s law in which film was granted First Amendment protection was driven in part by a change in the “emotional regimes” of US democracy, or emotions/performances of emotion that are part of legitimate political culture. The legal understanding of how film does or does not contribute to democratic political culture tracks historical shifts in these emotional regimes. In the teens, elites feared the activation of the masses, as crowds, in political uprisings. By 1950, elite fears had turned to passive audiences, “narcotized” masses that might easily be seduced by totalitarian demagogues.  相似文献
