To examine whether anticipatory attention or expectancy is a cognitive process that is automatic or requires conscious control, we employed a paired-stimulus event-related potential paradigm during the transition to sleep. The slow negative ERP wave observed between two successive stimuli, the Contingent Negative Variation , reflects attention and expectancy to the second stimulus. Thirteen good sleepers were instructed to respond to the second stimulus in a pair during waking sessions. In a non-response paradigm modified for sleep, participants then fell asleep (...) while tones played. As expected, N1 decreased and P2 increased in amplitude systematically with the loss of consciousness at sleep onset; the CNV was increasingly more positive. Sleep onset latency was correlated with the amplitude of the CNV. The systematic attenuation of the CNV waveform at sleep onset and its absence in sleep indicates that anticipatory attention requires endogenous conscious control. (shrink)

This article applies Karl Polanyi’s concept of a double movement to the trajectory of rural state policies in China since 1949. It argues that Chinese socialism created a contradictory social contract that has fueled an ongoing struggle between state and peasantry over the surplus generated from rural land. This struggle has shaped a historical oscillation between state policies that facilitate extraction of agricultural surpluses and policies that introduce social protections in the form of household farming and revitalized collective ownership. Based (...) on secondary sources, this article compares the arc of rural policies during the Mao era and in the transition to and during the current state capitalist period. Then, based on original interview-based and ethnographic fieldwork undertaken in rural Sichuan Province, it analyzes the current introduction of urban and agrarian capital into the rural economy, revealing dynamics of a current countermovement from state-led extraction to compromise.

Haptic-based vibrotactile biofeedback (BF) is a promising technique to improve rehabilitation of balance in stroke patients. However, the extent to which BF training changes temporal structure of the center of pressure (CoP) trajectories remains unknown. This study aimed to investigate the effect of vibrotactile BF training on the temporal structure of CoP during quiet stance in chronic stroke patients using detrended fluctuation analysis (DFA). Nine chronic stroke patients (age; 81.56±44 months post-stroke) received a balance training regimen using a vibrotactile BF (...) system twice a week over four weeks. A Wii Balance board was used to record five 30 s trials of quiet stance pre- and post-training at 50 Hz. DFA revealed presence of two linear scaling regions in CoP indicating presence of fast- and slow-scale fluctuations. Averaged across all trials, fast-scale fluctuations showed persistent dynamics ( = 1.05 ±.08 for ML and  = 0.99 ±.17 for AP) and slow-scale fluctuations were anti-persistent ( = 0.35 ±.05 for ML and  = 0.32 ±.05 for AP). The slow-scale dynamics of ML CoP in stroke patients decreased from pre-training to post-BF training ( = 0.40 ±.13 vs. 0.31 ±.09). These results suggest that the vibrotactile BF training affects postural control strategy used by chronic stroke patients in the ML direction. Results of the DFA are further discussed in the context of balance training using vibrotactile BF and interpreted from the perspective of intermittent control of upright stance. (shrink)

We argue that the appraisal of models in social epistemology requires conceiving of them as argumentative devices, taking into account the argumentative context and adopting a family-of-models perspective. We draw up such an account and show how it makes it easier to see the value and limits of the use of models in social epistemology. To illustrate our points, we document and explicate the argumentative role of epistemic landscape models in social epistemology and highlight their limitations. We also claim that (...) our account could be fruitfully used in appraising other models in philosophy and science. (shrink)

Philosophy Then and Now provides an innovative and engaging blend of introductory text with classic and contemporary readings. Each of the eight parts begins with an introductory section on the major ideas associated with a seminal figure from the history of philosophy. This is followed by key selections from the essential writings of that philosopher, as well as influential selections from contemporary figures. Key figures covered include: Socrates, Aquinas, Locke, Descartes, Mill, Nietzsche, Marx, and Sartre. By focusing on the core (...) themes, issues and problems of philosophy, the volume motivates student interest in the subject, and represents a distinctive text for all introductory courses in philosophy.
