Sprache und IntentionalitÀt : der Zusammenbruch des Kognitivismus
Das Programm fĂŒr eine sog. kognitive Wissenschaft scheitert an der Aufgabe, der IntentionalitĂ€t mentaler ZustĂ€nde und VorgĂ€nge Rechnung zu tragen. Insbesondere scheitert die kognitive Linguistik an der IntentionalitĂ€t des Sprechens. Damit wird auch die Sprachauffassung vor allem der generativen Grammatik hinfĂ€llig; sie muĂ durch eine Weiterentwicklung der Sprachbegriffe ersetzt werden, die man in der Sprachwissenschaft bei der praktischen Arbeit im allgemeinen voraussetzt. Eine Neuorientierung in der Sprachwissenschaft scheint erforderlich
Towards a general theory of word formation: the Process Model
Foreword. The present essayâlonger than a paper but shorter than a
bookâcharacterizes the Process Model of Word Formation that represents a new
approach to word formation intermediate between constructionist and generative
approaches; the model will be elaborated in detail in: Lieb, Hans-Heinrich (in
prep.), The Process Model of Word Formation and Inflection.

Das Ramirezsche Integral Und Die Lösung Der Gleichung Ïf= α Im Bereich Der BeschrĂ€ankten Formen
Paper by Hans Grauert and Ingo Lie
Existence and stability of solitons for the nonlinear Schr\"odinger equation on hyperbolic space
We study the existence and stability of ground state solutions or solitons to
a nonlinear stationary equation on hyperbolic space. The method of
concentration compactness applies and shows that the results correlate strongly
to those of Euclidean space.Comment: New: As noted in Banica-Duyckaerts (arXiv:1411.0846), Section 5
should read that for sufficiently large mass, sub-critical problems can be
solved via energy minimization for all d \geq 2 and as a result
Cazenave-Lions results can be applied in Section 6 with the same restriction.
These requirements were addressed by the subsequent work with Metcalfe and
Taylor in arXiv:1203.361
The use of weights to account for non-response and drop-out
Background: Empirical studies in psychiatric research and other fields often show substantially high refusal and drop-out rates. Non-participation and drop-out may introduce a bias whose magnitude depends on how strongly its determinants are related to the respective parameter of interest.
Methods: When most information is missing, the standard approach is to estimate each respondentâs probability of participating and assign each respondent a weight that is inversely proportional to this probability. This paper contains a review of the major ideas and principles regarding the computation of statistical weights and the analysis of weighted data.
Results: A short software review for weighted data is provided and the use of statistical weights is illustrated through data from the EDSP (Early Developmental Stages of Psychopathology) Study. The results show that disregarding different sampling and response probabilities can have a major impact on estimated odds ratios.
Conclusions: The benefit of using statistical weights in reducing sampling bias should be balanced against increased variances in the weighted parameter estimates
Authors reply to Mushtaq and Minn-Dinâs letter [Anxiety disorders in mothers and their children : prospective-longitudinal community study]
As Mushtaq & Minn-Din correctly point out, Bijl et al1 did not find associations between prevalence rates of any psychiatric disorder (including anxiety disorders) in children and anxiety-related symptoms in parents. However, one must be aware of several methodological differences to our investigation: the results cited by Mushtaq & Minn-Din are based on 12-month prevalence rates and multivariate logistic regression analysis additionally controlling for childhood adversities and socio-demographic characteristics. We would like to clarify that the results of the Bijl et al paper are much more comparable with our study and that the results we are actually referring to are those based on life-time prevalence rates of psychiatric disorders in children without controlling for childhood adversities and reported separately for the various offspring disorders. Here, Bijl et al clearly report associations between anxiety in parents and children. In addition, it is true that the adult children in the Bijl et al study were considerably older (18â65 years) than the offspring in our study (17â21 years at follow-up). We would like to add that there are other substantial ways in which the studies differ; for example, our use of assessment via direct interviews v. family-history information.1 Nevertheless, we do not see why our claim that we confirm and extend the Bijl et al study should be problematic, especially when taking into account the low median for age at onset of anxiety disorders.2 We would also like to point out that both studies were community-based so that the use of the term âpatientsâ by Mushtaq & Minn-Din is slightly misleading
Influence of Temperature, Hypercapnia, and Development on the Relative Expression of Different Hemocyanin Isoforms in the Common Cuttlefish Sepia officinalis
The cuttlefish Sepia officinalis expresses several hemocyanin isoforms with potentially different pH
optima, indicating their reliance on efficient pH regulation in the blood. Ongoing ocean warming
and acidification could influence the oxygen-binding properties of respiratory pigments in
ectothermic marine invertebrates. This study examined whether S. officinalis differentially
expresses individual hemocyanin isoforms to maintain optimal oxygen transport during
development and acclimation to elevated seawater pCO2 and temperature. Using quantitative
PCR, we measured relative mRNA expression levels of three different hemocyanin isoforms in
several ontogenetic stages (embryos, hatchlings, juveniles, and adults), under different
temperatures and elevated seawater pCO2. Our results indicate moderately altered hemocyanin
expression in all embryonic stages acclimated to higher pCO2, while hemocyanin expression in
hatchlings and juveniles remained unaffected. During the course of development, total hemocyanin
expression increased independently of pCO2 or thermal acclimation status. Expression of isoform 3
is reported for the first time in a cephalopod in this study and was found to be generally low but
highest in the embryonic stages (0.2% of total expression). Despite variable hemocyanin expression,
hemolymph total protein concentrations remained constant in the experimental groups. Our data
provide first evidence that ontogeny has a stronger influence on hemocyanin isoform expression
than the environmental conditions chosen, and they suggest that hemocyanin protein abundance
in response to thermal acclimation is regulated by post-transcriptional/translational rather than by
transcriptional modifications
