Long-range connections mirror and link microarchitectural and cognitive hierarchies in the human brain

Core features of higher-order cognition are hypothesized to be implemented via distributed cortical networks that are linked via long-range connections. However, these connections are biologically expensive, and it is unknown how the computational advantages long-range connections provide overcome the associated wiring costs. Our study investigated this question by exploring the relationship between long-range functional connections and local cortical microarchitecture. Specifically, our work (i) profiled distant cortical connectivity using resting-state fMRI and cortico-cortical geodesic distance mapping, (ii) assessed how long-range connections reflect local brain microarchitecture, and (iii) studied the microarchitectural similarity of regions connected through long-range connections. Analysis of two independent datasets indicated that sensory and motor areas had more clustered short-range connectivity patterns, while transmodal association cortices, including regions of the default mode network, were characterized by distributed, long-range connections. Confirmatory meta-analysis suggested that this topographical difference mirrored a shift in cognitive function, from perception/action towards emotional and social cognitive processing. Analysis of myelin-sensitive in vivo MRI in the same participants as well as post mortem histology and gene expression established that gradients in functional connectivity distance are paralleled by those present in cortical microarchitecture. Moreover, long-range connections were found to link together spatially remote regions of association cortex with an unexpectedly similar microarchitecture. These findings provide novel insights into how the organization of distributed functional networks in transmodal association cortex contribute to cognition, because they suggest that long-range connections link together distant islands of association cortex with similar microstructural features.

Doing Post-Western sociology in Central and Eastern Europe before and after the Great Change: some epistemological questions

Analyzing the sociology in Central and Eastern Europe before and after the Great Change in 1989, the article aims to present the main epistemological questions that Post-Western sociology raises for the discipline of sociology as a whole. The focus is put on a paradoxical feature in the development of sociology in the countries of Central and Eastern Europe: before 1989, under conditions of Marxist monoparadigmality, relative isolation of scientific cognition, and political and ideological pressure, sociological research in these countries was characterized by methodological rigor and conceptual innovativeness, while after 1989, in the context of institutionalized plurality of paradigms (polyparadigmality), and intensive scientific exchange, the dominant tendency is—for social scientists in the countries in question—to borrow methodologies, theories, and concepts from the Western sociological tradition, without analyzing the epistemic relevance of these loans with regard to the societies in which they are applied. This paradox is examined in terms of sociological production in two research fields: the general sociological theory of society and sociology of youth. Comparing studies and analyses carried out in these two fields in Central and Eastern Europe before and after the Great Change, the article demonstrates that Post-Western sociology is a valid research posture for a wide variety of sociological practices regardless of the concrete national, theoretical, or institutional frameworks in which researchers are working. Sensitivity to the context of research is what permits Post-Western sociology to eliminate cognitive hierarchies and inequalities and restores the epistemic autonomy of each cognitive practice, emphasizing the inevitable cultural variations in the interpretation of one and the same phenomenon and the impact of these variations on methodology. In this sense, Post-Western sociology raises important epistemological problems regarding the relationship between maintaining the disciplinary principles of sociological knowledge on the one hand, and the application of those principles in different epistemic contexts on the other hand. The main question could be formulated as follows: how does Post-Western sociology enrich the deontological and epistemological principles of the discipline and in what way does it contribute to developing its scientific project?

Means-End Matrix and Deduction in Consumption Behavior Research

This study adopts matrix operations to deduce the logic of the means-end laddering approach and uses flowcharts to illustrate the steps in every laddering-matrix process. In addition to helping programmers understand the logic of means-end laddering for writing computer programs, these flowcharts also provide marketers with the main concepts of means-end chain (MEC) methodology in order to develop better marketing strategies. This study has three major contributions: (1) to propose improvements for constructing the cognitive hierarchies of consumer-product knowledge, (2) to alleviate the weakness of traditional MEC methodology, and (3) to provide the logic of laddering-matrix programming procedure to improve the design of MEC computer software.
