In his book Aion, Jung describes something like a quasi-Hegelian progressive historical realization of the Self in a perspective similar to Fernand Braudel’s longue durée history. This article deals with a similar perspective, as it tries to focus on what we may call a “cultural complex” yet within its unfolding in historical time and belonging not to just one specific cultural group, but to a large cultural basin, which we may indicate as the “West”. This complex marks the birth and development of modernity. The depth, pervasiveness and duration of this cultural complex permeates the lives and psychologies of all of those that are part of it. Therefore, every analytical project must take into account the underlying emotional, epistemic and social field within which this complex constellates. One of the main features of this (trans)cultural complex, strictly connected with the progressive fragmentation of the self and the transformation of the numinosum with its meaning-giving force, is paranoia. This article analyses the historical and cultural features that produce paranoia and fragmentation and determine paranoid symptoms and attitudes. 相似文献

Few studies have assessed the effects of stress on in vivo platelet activation. In the present study, hypobaric hypoxia induced by rapid decompression during high-altitude simulated flight in a hypobaric chamber was used to evaluate the effects of environmental stress on salivary cortisol and urinary thromboxane metabolite (TXM) excretion, a noninvasive marker of in vivo platelet function. Twenty-one male aviators (mean ± SD age = 36 ± 7 years) experiencing hypoxia by removing their oxygen mask for 4-5 min during a simulated flight to 25,000 ft (7,620 m; pO(2) = 59.17 mmHg) and a matched control group of thirteen flying instructors wearing oxygen masks during the challenge, were studied. Hypobaric hypoxia induced a transient significant increase (P < 0.001) in the aviators' salivary cortisol concentration; the overall pattern of diurnal cortisol fluctuation was maintained in both groups. Urinary TXM showed a significant ~30% reduction (P < 0.01) after the chamber session in aviators exposed to hypobaric hypoxia, but not in controls. A significant inverse correlation was found between salivary cortisol and urinary TXM in aviators (r = - 0.64, P = 0.0015). Salivary cortisol was a significant predictor (P < 0.001) for urinary TXM concentrations in aviators. In conclusion, here we observed that an acute stress-induced salivary cortisol increase was associated with reduced urinary thromboxane biosynthesis, providing the first indirect evidence for an inhibitory effect of acute stress on in vivo platelet function. 相似文献

Is there a correspondence between subjective and objective wellbeing indicators in development programs? We investigate this question by evaluating the impact of Fair Trade affiliation on the subjective wellbeing of a sample of Peruvian (treatment and control) producers from two different Fair Trade projects in two socioeconomic environments, one relatively poorer (Juliaca) and the other relatively more affluent (Chulucanas). We find a direct and an indirect effect. The direct effect acts positively via affiliation years in the poorer project and via trade diversification in both projects. The indirect effect acts through the reduction of poverty and relative income. Consistently with the concave income-happiness assumption, the variables generating the indirect effect have a much weaker impact for producers living in the relatively better-off socioeconomic environment, net of the lower FT economic impact in this area. 相似文献

Attention has often been considered to be a gateway to consciousness (Posner, Proceedings of the National Academy of Sciences of the United States of America, 91(16), 7398–7403, 1994). However, its relationship with conscious perception (CP) remains highly controversial. While theoretical models and experimental data support the role of attention in CP (Chica, Lasaponara, Lupiáñez, Doricchi, &; Bartolomeo, NeuroImage, 51, 1205–1212, 2010; Dehaene, Changeux, Naccache, Sackur, &; Sergent, Trends in Cognitive Sciences, 10, 204–211, 2006; Mack &; Rock, Inattentional blindness, 1998), recent studies have claimed that at least some forms of attention—endogenous or top-down spatial attention—are neither sufficient nor necessary for CP (Koch &; Tsuchiya, Trends in Cognitive Sciences, 11, 16–22, 2007). In the present experiments, we demonstrate the importance of exogenously triggered attention for the modulation of CP. Weak or null effects were instead observed when attention was triggered endogenously. Our data are discussed in the framework of recent neuropsychological models (Dehaene et al., Trends in Cognitive Sciences, 10, 204–211, 2006), postulating that activity within reverberating frontoparietal networks, as colocalized with spatial--orienting systems, is the brain correlate of consciously processed information. 相似文献
