In this study, voluntary and involuntary visual attention focused on different interpretations of a bistable image, were investigated using magnetoencephalography. A Necker cube with sinusoidally modulated pixels' intensity in the front and rear faces with frequencies 6.67 Hz and 8.57 Hz, respectively, was presented to 12 healthy volunteers, who interpreted the cube as either left- or right-oriented. The tags of these frequencies and their second harmonics were identified in the average Fourier spectra of the MEG data recorded from the visual (...) cortex. In the first part of the experiment, the subjects were asked to voluntarily control their attention by interpreting the cube orientation as either being on the left or right. Accordingly, we observed the dominance of the corresponding spectral component, and voluntary attention performance was measured. In the second part of the experiment, the subjects were asked to focus their gaze on a red marker at the center of the cube image without putting forth effort in its interpretation. The alternation of the dominant spectral energies at the second harmonics of the stimulation frequencies was treated as changes in the cube orientation. Based on the results of the first experimental stage and using a wavelet analysis, we developed a method which allowed us to identify the currently perceived cube orientation. Finally, we characterized involuntary attention using the distribution of dominance times when focusing attention on one of the cube orientations, which was related to voluntary attention performance and brain noise. In particular, we confirmed our hypothesis that higher attention performance is associated with stronger brain noise. (shrink)

So far, most ethical consumerism research has been contained within Western countries, thus limiting our understanding of the concept in emerging markets. Given the call for extending empirical-based knowledge for a better understanding of peculiarities, dynamics and country-level variations (i.e. social, cultural) in the context of ethical consumerism in emerging markets, this research cross-examines the interactive nature of individual- and country-level predictors of ethical consumerism in emerging and developed markets, employing a multilevel approach. At the individual level, we posit that (...) ethical consumerism is motivated by social and cultural capital. In contrast, at the contextual level, we choose country-level affluence as an influential factor that might impact the relationship between socio-cultural capital and ethical consumerism. The study uses the International Social Survey Programme’s (ISSP) 2014 citizenship module data set (including 34 countries) for investigating individual-level predictors (of social and cultural capital). The GDP per capita data from the International Monetary Fund’s (IMF) Economic Outlook database was used to examine the cross-level interactions between individual-level predictors and country-level affluence. The findings suggest that social and cultural capitals positively influence ethical consumerism in emerging and developed markets. Further, country-level affluence moderates the relationship between socio-cultural capital and ethical consumerism for both markets. However, cultural capital proved to be a stronger predictor of ethical consumerism as country-level affluence increases. The research findings highlight meaningful cross-country-level interactions that help further understand the basis of ethical consumerism from a global perspective. (shrink)

This essay is my review of Colleen Dyble’s book, Taming Leviathan: Waging a War of Ideas around the World. Dyble is affiliated with the legendary classical liberal British think tank, the Institute of Economic Affairs. Her anthology is a collection of essays by people around the world who have been involved with similar free-market think tanks in countries with historically statist economic systems. These writers include Greg Lindsay, founder of the Center for Independent Studies in Australia; Margaret Tse, of the (...) Instituto Liberdade in Brazil; Michael Walker, co-founder of the Fraser Institute in Canada; Cristian Larroulet, of Libertad y Desarrollo in Chile; Giancarlo Ibarguen, of the Center for Economic and Social Studies in Guatemala (which actually founded a free-market-oriented university); Parth Shah, founder of the Center for Civil Society in India; Daniel Doron, co-founder of the Israeli Center for Social and Economic Progress; Alberto Mingardi, of the Instituto Bruno Leoni in Italy; Masaru Uchigama, founder of the Japanese for Tax Reform; Elena Leontjeva, co-founder of the Lithuanian Free Market Institute; Alexander Magno, co-founder of the Foundation for Economic Freedom in the Philippines; and last, Leon Louw, of the Free Market Foundation of South Africa. I then discuss seven important reasons why classical liberal think tanks are so important in modern societies. (shrink)
