The big five: Discovering linguistic characteristics that typify distinct personality traits across Yahoo! answers members

Indexación: Scopus.This work was partially supported by the project FONDECYT “Bridging the Gap between Askers and Answers in Community Question Answering Services” (11130094) funded by the Chilean Government.In psychology, it is widely believed that there are five big factors that determine the different personality traits: Extraversion, Agreeableness, Conscientiousness and Neuroticism as well as Openness. In the last years, researchers have started to examine how these factors are manifested across several social networks like Facebook and Twitter. However, to the best of our knowledge, other kinds of social networks such as social/informational question-answering communities (e.g., Yahoo! Answers) have been left unexplored. Therefore, this work explores several predictive models to automatically recognize these factors across Yahoo! Answers members. As a means of devising powerful generalizations, these models were combined with assorted linguistic features. Since we do not have access to ask community members to volunteer for taking the personality test, we built a study corpus by conducting a discourse analysis based on deconstructing the test into 112 adjectives. Our results reveal that it is plausible to lessen the dependency upon answered tests and that effective models across distinct factors are sharply different. Also, sentiment analysis and dependency parsing proven to be fundamental to deal with extraversion, agreeableness and conscientiousness. Furthermore, medium and low levels of neuroticism were found to be related to initial stages of depression and anxiety disorders. © 2018 Lithuanian Institute of Philosophy and Sociology.

An algebraic model for rational naïve-commutative ring SO(2)-spectra and equivariant elliptic cohomology

Equipping a non-equivariant topological E∞-operad with the trivial G-action gives an operad in G-spaces. For a G-spectrum, being an algebra over this operad does not provide any multiplicative norm maps on homotopy groups. Algebras over this operad are called naïve-commutative ring G-spectra. In this paper we take G=SO(2) and we show that commutative algebras in the algebraic model for rational SO(2)-spectra model rational naïve-commutative ring SO(2)-spectra. In particular, this applies to show that the SO(2)-equivariant cohomology associated to an elliptic curve C of Greenlees (Topology 44(6):1213–1279, 2005) is represented by an E∞-ring spectrum. Moreover, the category of modules over that E∞-ring spectrum is equivalent to the derived category of sheaves over the elliptic curve C with the Zariski torsion point topology

Developing as a learning organization : a Hong Kong case of sensegiving and career contracts

I discuss a qualitative case study of a Hong Kong-based utility company where commercial imperatives drove, but also circumscribed, development toward ‘Learning Organization’ (LO) ideals. The case illuminates the paradox of promoting greater openness and creativity through top down sensegiving, as many managers and professionals participated in collective development towards LO ideals, but were seduced into what nearly became a propaganda trap. The case also highlights the importance of honouring psychological contracts, in that a covenant with the workforce, which leveraged the company’s dominant industry position, restored an atmosphere of mutuality with a marginalized rump. Noting that the focal company may have been blessed with relatively munificent circumstances, I conclude by identifying four viability tasks that aspiring LOs may need to perform continually in order to forestall resentment and disillusion

Media, Meaning, and Context Loss in Ephemeral Communication Platforms: A Qualitative Investigation of Snapchat

Most social media platforms are persistent in nature, enabling users to re-visit content at their discretion. Platforms with design features that support ephemeral communications, such as Snapchat, have become increasingly popular. During the course of our empirical study, we interviewed 15 Snapchat users about their experiences and practices. Our data reveal that Snapchat users experienced different types of loss, including media, meaning, and context loss, and developed workarounds to deal with those losses, including preemptive action and collaborative saving practices. Our findings revealed a conflict between the user's expectation of the affordance the ephemeral platforms would provide, and the actions user's followed

Boolean algebras, Morita invariance, and the algebraic K-theory of Lawvere theories

The algebraic K-theory of Lawvere theories is a conceptual device to elucidate the stable homology of the symmetry groups of algebraic structures such as the permutation groups and the automorphism groups of free groups. In this paper, we fully address the question of how Morita equivalence classes of Lawvere theories interact with algebraic K-theory. On the one hand, we show that the higher algebraic K-theory is invariant under passage to matrix theories. On the other hand, we show that the higher algebraic K-theory is not fully Morita invariant because of the behavior of idempotents in non-additive contexts: We compute the K-theory of all Lawvere theories Morita equivalent to the theory of Boolean algebras.Comment: 20 pages. This updated paper discusses the work on Morita equivalence of Lawvere theories that appeared in version one. In order to better highlight the two separate directions of the results in that first version, the material on assembly maps has been incorporated into a second paper, arXiv:2112.0700
