Practical Implications

Purpose The main purpose of this study is to examine the role of quality as a determinant of a cross-sectional variation in country-level stock returns. The study attempts to address the question: Is there any special premium for top-quality stock markets with decent profitability, indebtedness and liquidity ratios? Design/methodology/approach The computations are based on the listings of 66 country portfolios over the period between 2000 and 2013. Long/short country portfolios from sorts on characteristics related to quality are examined with asset-pricing models. Findings The inter-market variation in returns may be explained with profitability and debt ratios: the more profitable and the less indebted is the stock market, the better is its performance. Moreover, the performance of country-level value, size and momentum strategies may be improved by double sorting on quality characteristics. Practical implications The practical implications include such issues as the global asset allocation, the development of investment products, asset pricing and investment performance measurement. The country selection strategies that are based on leverage and profitability prove to be a useful tool for investors with a global investment mandate. Furthermore, additional sorting on quality metrics may markedly improve the performance of inter-market value, size and momentum strategies. Originality/value This paper examines the role of quality metrics related to financial leverage, profitability and liquidity in explaining the cross-sectional variation in country returns.

Voxel Selection

AbstractIn neuroimaging, voxel-wise encoding models are a popular tool to predict brain activity elicited by a stimulus. To evaluate the accuracy of these predictions across multiple voxels, one can choose between multiple quality metrics. However, each quality metric requires specifying auxiliary parameters such as the number and selection criteria of voxels, whose influence on model validation is unknown. In this study, we systematically vary these parameters and observe their effects on three common quality metrics of voxel-wise encoding models in two open datasets of 3- and 7-Tesla BOLD fMRI activity elicited by musical stimuli. We show that such auxiliary parameters not only exert substantial influence on model validation, but also differ in how they affect each quality metric. Finally, we give several recommendations for validating voxel-wise encoding models that may limit variability due to different numbers of voxels, voxel selection criteria, and magnetic field strengths.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Sense Of Obligation

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.

Abstract The authors do the field of cultural evolution a service by exploring the role of non-social cognition in human cumulative technological culture, truly neglected in comparison with socio-cognitive abilities frequently assumed to be the primary drivers. Some specifics of their delineation of the critical factors are problematic, however. I highlight recent chimpanzee–human comparative findings that should help refine such analyses.

The Relationship

Abstract This commentary focuses upon the relationship between two themes in the target article: the ways in which a Markov blanket may be defined and the role of precision and salience in mediating the interactions between what is internal and external to a system. These each rest upon the different perspectives we might take while “choosing” a Markov blanket.
