On the mereological structure of complex states of affairs

The aim of this paper is to elucidate the mereological structure of complex states of affairs without relying on the problematic notion of structural universals. For this task tools from graph theory, lattice theory, and the theory of relational systems are employed. Our starting point is the mereology of similarity structures. Since similarity structures are structured sets, their mereology can be considered as a generalization of the mereology of ordinary sets. In general, the mereological systems arising from similarity structures turn out to be not Boolean but Heyting systems. Employing Armstrong??s notion of thick particulars, similarity structures are shown to capture the mereological structure of complex ??chemical states of affairs?? such as ??being butane?? or ??being isobutane??; structural universals are not needed.     

Just an anger synonym? Moral context influences predictors of disgust word use

Are verbal reports of disgust in moral situations specific indicators of the concept of disgust, or are they used metaphorically to refer to anger? In this experiment, participants read scenarios describing a violation of a norm either about the use of the body (bodily moral) or about harm and rights (socio-moral). They then expressed disgust and anger on verbal scales, and through facial expression endorsement measures. The use of disgust words in the socio-moral condition was largely predicted by anger words and only secondarily by disgust faces, whereas in the bodily moral condition the use of disgust words was predicted to a similar extent by disgust faces and anger words. Angry faces, however, never predicted disgust words independently of anger words. These results support a middle-ground position in which disgust words concerning socio-moral violations are not entirely a metaphor for anger, but bear some relationship to other representations of disgust. In the case of socio-moral violations, however, the use of disgust language is more strongly related to anger language, and less strongly to facial representations of disgust than in the case of bodily moral violations.     

Social class and wellbeing among staff and students in higher education settings: Mapping the problem and exploring underlying mechanisms

Within Higher Education (HE), staff and students from lower social class backgrounds often experience poorer wellbeing than their higher social class counterparts. Previous research conducted outside educational contexts has linked social class differences in wellbeing with differences in the extent to which low and high social class individuals feel respected (i.e., status), in control (i.e., autonomy), and connected with others (i.e., inclusion). However, to our knowledge, there has been no research that has investigated these psychosocial needs within HE settings. Furthermore, inclusion, status and autonomy are correlated, yet little is known about how these psychosocial needs contribute to wellbeing simultaneously, and independently, of one another. To fill these gaps, we report the results of two studies; firstly with HE students (Study 1; N = 305), and secondly with HE staff (Study 2; N = 261). Consistently across studies, reports of poor wellbeing were relatively common and more than twice as prevalent amongst lower social class staff and students compared to higher social class staff and students. Inclusion, status and autonomy each made a unique contribution and accounted for the relationship between social class and wellbeing (fully amongst students, and partially amongst staff members). These relationships held across various operationalizations of social class and when examining a range of facets of wellbeing. Social class along with inclusion, status and autonomy explained a substantial 40% of the variance in wellbeing. The present research contributes to the literature exploring how social class intersects with psychosocial needs to impact the wellbeing of staff and students within HE.     

Structural Universals as Structural Parts: Toward a General Theory of Parthood and Composition

David Lewis famously argued against structural universals since they allegedly required what he called a composition “sui generis” that differed from standard mereological composition. In this paper it is shown that, although traditional Boolean mereology does not describe parthood and composition in its full generality, a better and more comprehensive theory is provided by the foundational theory of categories. In this category-theoretical framework a theory of structural universals can be formulated that overcomes the conceptual difficulties that Lewis and his followers regarded as unsurmountable. As a concrete example of structural universals groups are considered in some detail.     

Branding the brain: A critical review and outlook

The application of neuroscience to marketing, and in particular to the consumer psychology of brands, has gained popularity over the past decade in the academic and the corporate world. In this paper, we provide an overview of the current and previous research in this area and explain why researchers and practitioners alike are excited about applying neuroscience to the consumer psychology of brands. We identify critical issues of past research and discuss how to address these issues in future research. We conclude with our vision of the future potential of research at the intersection of neuroscience and consumer psychology.     

Heyting Mereology as a Framework for Spatial Reasoning

In this paper it is shown that Heyting and Co-Heyting mereological systems provide a convenient conceptual framework for spatial reasoning, in which spatial concepts such as connectedness, interior parts, (exterior) contact, and boundary can be defined in a natural and intuitively appealing way. This fact refutes the wide-spread contention that mereology cannot deal with the more advanced aspects of spatial reasoning and therefore has to be enhanced by further non-mereological concepts to overcome its congenital limitations. The allegedly unmereological concept of boundary is treated in detail and shown to be essentially affected by mereological considerations. More precisely, the concept of boundary turns out to be realizable in a variety of different mereologically grounded versions. In particular, every part K of a Heyting algebra H gives rise to a well-behaved K-relative boundary operator.     

The Distribution of the Product Explains Normal Theory Mediation Confidence Interval Estimation

The distribution of the product has several useful applications. One of these applications is its use to form confidence intervals for the indirect effect as the product of 2 regression coefficients. The purpose of this article is to investigate how the moments of the distribution of the product explain normal theory mediation confidence interval coverage and imbalance. Values of the critical ratio for each random variable are used to demonstrate how the moments of the distribution of the product change across values of the critical ratio observed in research studies. Results of the simulation study showed that as skewness in absolute value increases, coverage decreases. And as skewness in absolute value and kurtosis increases, imbalance increases. The difference between testing the significance of the indirect effect using the normal theory versus the asymmetric distribution of the product is further illustrated with a real data example. This article is the first study to show the direct link between the distribution of the product and indirect effect confidence intervals and clarifies the results of previous simulation studies by showing why normal theory confidence intervals for indirect effects are often less accurate than those obtained from the asymmetric distribution of the product or from resampling methods.
