<Emphasis Type="Italic">Viktor Žirmunskij and German</Emphasis> Mundartforschung

German dialect geography developed, inter alia, as a means to compensate the shortcomings of the Young Grammarians’ approach to language. In contrast to the latter, it was conceived of to be a sociolinguistic project, constituting thereby one link between the development of Soviet and German linguistics. The article tries to answer such questions as who initially participated in transferring ideas of German dialectology to the Soviet Union and what kind of motivations underlay those transfers. Combining biographical facts with systematic aspects, the article surveys the filiations of some productive ideas with the help of archival sources, i.e. letters of the Soviet scholars Dinges (1891–1932) and Viktor Žirmunskij (1891–1971). Finally, I try to single out the elements in Žirmunskij dialect geography, which are specifically sociolinguistic.

The Crusades in Arab School Textbooks

This article examines the depiction of the Crusades in Arab school textbooks. In the introductory first part, perceptions of the Crusades manifest in Arab historiography are described. In addition, modern political discourses referring to the Crusades among Arab authors, politicians and representatives of political Islam are explained. In the second part, accounts of the Crusades in school textbooks from Saudi Arabia, Jordan, Syria, Lebanon, Palestine, Egypt, Libya and Tunisia are analysed, focusing on the sources used by the books' authors, the terminologies, conceptions, reasoning, and narratives found in them, and the results of the Crusades as they are portrayed. The third part concludes by explaining three different approaches to how the textbooks relate the history, and shows the historical sensibilities concerning the Crusades as taught by the schoolbooks.     

Hume’s Principle and Axiom V Reconsidered: Critical Reflections on Frege and His Interpreters

In this paper, I shall discuss several topics related to Frege’s paradigms of second-order abstraction principles and his logicism. The discussion includes a critical examination of some controversial views put forward mainly by Robin Jeshion, Tyler Burge, Crispin Wright, Richard Heck and John MacFarlane. In the introductory section, I try to shed light on the connection between logical abstraction and logical objects. The second section contains a critical appraisal of Frege’s notion of evidence and its interpretation by Jeshion, the introduction of the course-of-values operator and Frege’s attitude towards Axiom V, in the expression of which this operator occurs as the key primitive term. Axiom V says that the course-of-values of the function f is identical with the course-of-values of the function g if and only if f and g are coextensional. In the third section, I intend to show that in Die Grundlagen der Arithmetik (1884) Frege hardly could have construed Hume’s Principle (HP) as a primitive truth of logic and used it as an axiom governing the cardinality operator as a primitive sign. HP expresses that the number of Fs is identical with the number of Gs if and only if F and G are equinumerous. In the fourth section, I argue that Wright falls short of making a convincing case for the alleged analyticity of HP. In the final section, I canvass Heck’s arguments for his contention that Frege knew he could deduce the simplest laws of arithmetic from HP without invoking Axiom V. I argue that they do not carry conviction. I conclude this section by rejecting an interpretation concerning HP suggested by MacFarlane.     

Inductive Incompleteness

Nelson Goodman cast the ‘problem of induction’ as the task of articulating the principles and standards by which to distinguish valid from invalid inductive inferences. This paper explores some logical bounds on the ability of a rational reasoner to accomplish this task. By a simple argument, either an inductive inference method cannot admit its own fallibility, or there exists some non-inferable hypothesis whose non-inferability the method cannot infer (violating the principle of ‘negative introspection’). The paper discusses some implications of this limited self-knowledge for the justifiability of inductive inferences, auto-epistemic logic, and the epistemic foundations of game theory.     

Re-examining structural constraints on the initiation of bimanual movements: the role of starting locations, movement amplitudes, and target locations

Structural constraints affect the coordination of bimanual movements in ways that have been taken to suggest that the specification of different movement amplitudes is subject to strong intermanual interference effects. Most experiments taken to support this notion, however, confounded variations of movement amplitudes with symmetry in starting locations and variations in target location. The present experiment was designed to further investigate the relative influence of the parameters starting location, movement amplitude, and target location on bimanual movement coordination. Participants performed simultaneous reaching movements with the left and right hand from same and different starting locations to same and different target locations. On each trial, two movements could match on none, one, or all of the parameters. We assessed the influence of each parameter by comparing conditions in which only a single parameter matched between the two hands with conditions in which all parameters differed. The reaction-time data revealed some challenging results for previous studies: (1) same starting locations significantly delayed movement initiation; (2) specifying movement amplitudes had virtually no effect on movement initiation, whereas (3) selecting same target locations significantly benefited the bimanual responses. These findings cannot be taken to support the notion that amplitude specification affects the initiation of bimanual movements. Rather, they support the notion that the initial starting locations of the two hands and the selection of target locations decide about the ease with which we perform bimanual reaching movements.     

Target-related coupling in bimanual reaching movements

While bimanual interference effects can be observed when symbolic cues indicate the parameter values of simultaneous reaching movements, these effects disappear under conditions in which the target locations of two movements are cued directly. The present study investigates the generalizability of these target-location cuing benefits to conditions in which symbolic cues are used to indicate target locations (i.e., the end points of bimanual movements). Participants were asked to move to two of four possible target locations, being located either at the same and different distances (Experiment 1), or in the same and different directions (Experiment 2). Circles and crosses served as symbolic target-location cues and were arranged in a symmetric or non-symmetric fashion over the four target locations. Each trial was preceded by a variable precuing interval. Results revealed faster initiation times for equivalent as compared to non-equivalent target locations (same vs. different cues). Moreover, the time course of prepartion suggests that this effect is in fact due to target-equivalence and not to cue-similarity. Bimanual interference relative to movement parameter values was not observed. These findings suggest that cuing target locations can dominate potential intermanual interference effects during the concurrent programming of different movement parameter values.     

Fibromyalgie und Leistungseinschränkung

Interdisciplinary guidelines allowed for new quality standards in pain appraisal. Simultaneously, the scientific notion of fibromyalgia changed from a subjectively overvalued malaise to a central disturbance of coping with stress, which is neurobiologically determined. Therefore, in this article a psychosomatics-based guide is given for the socio-medical appraisal of fibromyalgia with reference to the new International Classification for Functioning and Disability (ICF) of the World Health Organization (WHO). As illustration a case study is presented.     

Symbolic control of visual attention: Semantic constraints on the spatial distribution of attention

Humans routinely use spatial language to control the spatial distribution of attention. In so doing, spatial information may be communicated from one individual to another across opposing frames of reference, which in turn can lead to inconsistent mappings between symbols and directions (or locations). These inconsistencies may have important implications for the symbolic control of attention because they can be translated into differences in cue validity, a manipulation that is known to influence the focus of attention. This differential validity hypothesis was tested in Experiment 1 by comparing spatial word cues that were predicted to have high learned spatial validity (“above/below”) and low learned spatial validity (“left/right”). Consistent with this prediction, when two measures of selective attention were used, the results indicated that attention was less focused in response to “left/right” cues than in response to “above/below” cues, even when the actual validity of each of the cues was equal. In addition, Experiment 2 predicted that spatial words such as “left/right” would have lower spatial validity than would other directional symbols that specify direction along the horizontal axis, such as “←/→” cues. The results were also consistent with this hypothesis. Altogether, the present findings demonstrate important semantic-based constraints on the spatial distribution of attention.     

PALME

Background

Single mothers and their children are exposed to increased psychosocial burdens and risks. Nevertheless, in Germany offers of help especially designed for the needs of this group are lacking.

Method

An emotion-oriented parental training program (PALME, http://www.palme-elterntraining.de) based on the attachment theory was developed particularly for single mothers with preschool children. The training is guided by trained kindergarten nurses. The effectiveness of the parental training program on the measure of maternal psychological impairment, emotional competence and child problem behavior was investigated within a randomized, controlled study with 61 single mothers suffering from medium grade psychosocial impairment.

Results

Analyses of variance revealed significant group×time interaction effects in favor of the intervention group compared to controls. After the training the mothers showed improvement in their psychological impairment, depression and emotional competence. In addition, evidence suggests that behavioral problems of the children were reduced.

Conclusion

In view of the benefits of this parental training and its low costs it should be recommended as a regular offer of support for single mothers within community settings.
