Public Orchestra Funding in Germany – An Empirical Investigation

In this paper, we describe the institutional framework in which heavy subsidization of German classical orchestras takes place and provide figures on the structure and the level of public support. Moreover, we derive and test various hypotheses concerning the political-economic determinants of public orchestra support. We analyze the political support-maximizing calculus of local politicians – the relevant decision-makers for orchestra subsidization in Germany. We find that public funding increases with increasing population; public debt and budget figures exert strong influences on the level of support. In addition, conservative and liberal politicians tend to support classical orchestras more than Social Democratic and Green politicians do.     

Diagnostic Problem-Solving Process in Professional Contexts: Theory and Empirical Investigation in the Context of Car Mechatronics Using Computer-Generated Log-Files

This article deals with a theory-based investigation of the diagnostic problem-solving process in professional contexts. To begin with, a theory of the diagnostic problem-solving process was developed drawing on findings from different professional contexts. The theory distinguishes between four sub-processes of the diagnostic problem-solving process and includes several hypotheses. According to the theory, the quality of the sub-processes “representing information” and “testing hypotheses” causally influences the diagnostic problem-solving success. Additionally, the theory suggests that the influence of “testing hypotheses” on the problem-solving success is higher than the influence of “representing information”. Moreover, the theory assumes that the influence of the quality of “representing information” on the success is mediated by the quality of “testing hypotheses”. These hypotheses were examined in the context of car mechatronics using diagnostic problems of the car sector, a computer-based assessment and a sample of car mechatronic apprentices (N = 339). To operationalize the sub-processes’ quality, observable critical behavior was theoretically identified and extracted from computer-generated log-files. The empirical results were largely in line with the hypotheses and indicated a (very) first corroboration of the theory in the context of car mechatronics. The theory could be helpful to investigate and teach diagnostic problem solving in different professional contexts. Further studies, however, should scrutinize whether the theory applies to other studies and professional contexts.     

Sexuality education for young children: The role of parents

An important component of family life is sexuality education. Being comfortable with one's sexuality is an essential component of individual and family wellness. To this end, parents and teachers who intend to assist in young children's sexuality education must be comfortable and well informed.Nilufer P.

Automatic,semantics-based indexing of natural language texts for information retrieval systems

The fundamental idea of the work reported here is to extract index phrases from texts with the help of a single word concept dictionary and a thesaurus containing relations among concepts. The work is based on the fact, that, within every phrase, the single words the phrase is composed of are related in a certain well denned manner, the type of relations holding between concepts depending only on the concepts themselves. Therefore relations can be stored in a semantic network. The algorithm described extracts single word concepts from texts and combines them to phrases using the semantic relations between these concepts, which are stored in the network. The results obtained show that phrase extraction from texts by this semantic method is possible and offers many advantages over other (purely syntactic or statistic) methods concerning preciseness and completeness of the meaning representation of the text. But the results show, too, that some syntactic and morphologic “filtering” should be included for effectivity reasons.     

The dimensionality and measurement of destructive instructor-leadership

ABSTRACT

The conceptualization of destructive leadership has received increasing attention in recent times. Accordingly, researchers have developed a theoretical model of destructive leadership that highlights two manifestations as follows: (1) leading followers towards goals that contradict the organization’s interests and (2) the use of harmful methods in leading followers. The two manifestations of destructive leadership point to the concept being multidimensional. However, researchers rarely investigate the dimensionality of destructive leadership when measuring the concept in general and in instructor–student relationships. Moreover, the most prominent measure of destructive leadership fails to capture its two manifestations adequately. To address the apparent mismatch between the theory and measurement of destructive instructor-leadership, we enhance an existing measure of destructive leadership. Using a sample of 174 students from the U.K., the findings indicated that the two manifestations of destructive instructor-leadership can be measured by 13 items, and was composed of three dimensions including, irresponsibility, victimization and callous communication. These findings along with limitations and suggestions for future research are discussed.     

Believing in Neuromyths Makes Neither a Bad Nor Good Student‐Teacher: The Relationship between Neuromyths and Academic Achievement in Teacher Education

Neuromyths have been discussed to detrimentally affect educational practice, but the evidence for this assumption is still very scarce. We investigated whether 255 student‐teacher' beliefs in neuromyths are related to their academic achievement (overall grade point averages and first‐year practical courses). Believing or rejecting neuromyths that make no direct assumptions about learners' educability was not related to academic achievement. Believing in neuromyths that explicitly deny the educability of learners was only marginally related to academic achievement. We conclude that self‐reported beliefs in neuromyths do not differentiate between high‐ and low‐achieving initial teacher education students.

RTP payload format for H.264/SVC scalable video coding

The scalable extension of H.264/AVC, known as scalable video coding or SVC, is currently the main focus of the Joint Video Team‘s work. In its present working draft, the higher level syntax of SVC follows the design principles of H.264/AVC.Self-contained network abstraction layer units (NAL units) form natural entities for packetization. The SVC specification is by no means finalized yet, but nevertheless the work towards an optimized RTP payload format has already started. RFC 3984, the RTP payload specification for H.264/AVC has been taken as a starting point, but it became quickly clear that the scalable features of SVC require adaptation in at least the areas of capability/operation point signaling and documentation of the extended NAL unit header. This paper first gives an overview of the history of scalable video coding, and then reviews the video coding layer (VCL)and NAL of the latest SVC draft specification. Finally, it discusses different aspects of the draft SVC RTP payload format, including the design criteria, use cases, signaling and payload structure.     

Comprehending animations: Effects of spatial cueing versus temporal scaling

In the present experiment the animation of the operating mechanism of a pendulum clock was used in order to compare the effects of spatial cueing with those of temporal scaling on the comprehension of the animation. The presentation speed of the clock mechanism (normal vs. fast) and signalling cues to three different parts of the mechanism (weight, pendulum, and an irrelevant gear as blinking elements) were used in a 2 × 3 between subjects design with 144 participants. It was found that compared to normal speed condition, understanding was improved in the fast speed condition, but was unaffected by any of the cueing conditions. The results indicate that, although guidance of attention to relevant parts of an animation is often seen as a key to effective instructional design, the way temporal manipulations affect understanding is independent from local attention guiding.     

Kulturelle Partizipation bei Jugendlichen als Feld der Person-Umwelt-Transaktion

What motivates adolescents to cultural participation? This question is important for the discourse on aesthetic education, in which cultural participation is regarded as contributing to the development of adolescents’ personality, values, and competencies. However, research on this issue suffers from fragmentation. Unconnected research on cultural participation from the sociology, cultural education, and differential psychology literature are reviewed, and it is shown how they may be supplemented using the theory of planned behaviour and integrated in a single theoretical framework. This framework centers on cultural participation as a field of person-environment transaction. Participation is regarded as being determined by both person and environmental variables and has the potential of changing these variables. On both its person and its environment sides, the model contains domain-specific determinants that mediate effects of the domain-general variables on which research on cultural participation has focused up to now. An overview of own empirical research related to the model is given and avenues for future research on cultural participation are discussed.
