Metaphor as categorisation: a connectionist implementation
A key issue for models of metaphor comprehension is to explain how in some metaphorical comparison , only some features of B are transferred to A. The features of B that are transferred to A depend both on A and on B. This is the central thrust of Black's well known interaction theory of metaphor comprehension (1979). However, this theory is somewhat abstract, and it is not obvious how it may be implemented in terms of mental representations and processes. In this paper we describe a simple computational model of on-line metaphor comprehension which combines Black's interaction theory with the idea that metaphor comprehension is a type of categorisation process (Glucksberg & Keysar, 1990, 1993). The model is based on a distributed connectionist network depicting semantic memory (McClelland & Rumelhart, 1986). The network learns feature-based information about various concepts. A metaphor is comprehended by applying a representation of the first term A to the network storing knowledge of the second term B, in an attempt to categorise it as an exemplar of B. The output of this network is a representation of A transformed by the knowledge of B. We explain how this process embodies an interaction of knowledge between the two terms of the metaphor, how it accords with the contemporary theory of metaphor stating that comprehension for literal and metaphorical comparisons is carried out by identical mechanisms (Gibbs, 1994), and how it accounts for both existing empirical evidence (Glucksberg, McGlone, & Manfredi, 1997) and generates new predictions. In this model, the distinction between literal and metaphorical language is one of degree, not of kind
LOGICAL AND PSYCHOLOGICAL PARTITIONING OF MIND: DEPICTING THE SAME MAP?
The aim of this paper is to demonstrate that empirically delimited structures of mind are also differentiable by means of systematic logical analysis. In the sake of this aim, the paper first summarizes Demetriou's theory of cognitive organization and growth. This theory assumes that the mind is a multistructural entity that develops across three fronts: the processing system that constrains processing potentials, a set of specialized structural systems (SSSs) that guide processing within different reality and knowledge domains, and a hypecognitive system that monitors and controls the functioning of all other systems. In the second part the paper focuses on the SSSs, which are the target of our logical analysis, and it summarizes a series of empirical studies demonstrating their autonomous operation. The third part develops the logical proof showing that each SSS involves a kernel element that cannot be reduced to standard logic or to any other SSS. The implications of this analysis for the general theory of knowledge and cognitive development are discussed in the concluding part of the paper

The evolution of innovation networks : the case of a German automotive network
In this paper we outline a conceptual framework for depicting network development patterns of interfirm innovation networks and for analyzing the dynamic evolution of an R&D network in the German automotive industry. We test the drivers of evolutionary change processes of a network which is based on subsidised R&D projects in the 10 year period between 1998 and 2007. For this purpose a stochastic actor-based model is applied to estimate the impact of various drivers of network change. We test hypotheses in the innovation and evolutionary economics framework and show that structural positions of firms as well as actor covariates and dyadic covariates are influential determinants of network evolution
Distributed cortical networks for syntax processing: Broca's area as the common denominator
Different types of syntactic information (word category, grammatical gender) are processed at different times during word recognition. However, it is an open issue which brain systems support these processes. In the present event-related fMRI study, subjects performed either a syntactic gender decision task on German nouns (GEN), a word category decision task (WC, nouns vs. prepositions), or a physical baseline task (BASE). Reaction times in WC were faster than in GEN, supporting earlier electrophysiological results. Relative to BASE, both syntactic tasks activated the inferior tip of BA 44. In addition, BA 45 showed activation in GEN, whereas BA 47 was activated in WC. The imaging data indicate that the inferior portion of BA 44 together with type-specific prefrontal areas supports both initial word category related and later syntactic processes

Whole-part and part-whole inferences in generative and cognitive linguistics
The paper focuses on
the relation between the analytical philosophy of science and modular and
holistic approaches to cognitive linguistics, respectively. The authors show
that Chomsky's as well as Bierwisch & Lang's and Lakoff & Johnson's
approaches make substantial use of non-demonstrative inferences which the
standard view of the analytical philosophy of science evaluates as fallacies.
By outlining a metatheoretical framework focusing on plausible inferences, the
authors argue that the inferences the theories mentioned make use of are
plausible rather than fallacious. This finding illuminates basic aspects of
theory formation in linguistics and motivates the revaluation of the
methodological foundations of linguistic theories
Leveraging diverse ecosystem partners for innovation: the roles of regional innovation environment and partnership heterogeneity
Although prior studies investigated the influence of partner diversity
on focal firms’ innovation performance, they failed to consider
partners’ ecosystem positions and the roles of regional innovation
environment and partnership heterogeneity. To fill these gaps,
this study examines the relationship between supplier diversity,
customer diversity, regional innovation environment, partnership
heterogeneity and innovation performance to provide a comprehensive
and throughout understanding of the influence of partner
diversity on innovation performance. Based on data of 188
Chinese manufacturing firms, this article finds that both diversities
of upstream suppliers and that of downstream customers contribute
to innovation performance. Regional innovation environment
and partnership heterogeneity moderate the influences of supplier
diversity and customer diversity on innovation performance.
In a favourable regional innovation environment, the benefits of
diverse upstream suppliers for innovation are eroded, while the
benefits of diverse downstream customers for innovation are
enhanced. Partnership heterogeneity with suppliers can mitigate
the moderating effect of regional innovation environment on the
relationship between supplier diversity and innovation performance.
These findings advance the literature on partner diversity
and innovation performance, thus providing fine-grained managerial
implications to firms to orchestrate diverse inter-organizational
partners for innovation
