The quantum theory of the laser of Scully and Lamb is used to determine the longest-lived states of the quantized field in an idealized, single-mode laser cavity. It is shown that quasiclassical states (states with well-defined phase and amplitude) are naturally selected. A quantum trajectory analysis provides some insight as to why this is so.

Women are important actors in smallholder farmer milk production. Therefore, female input in the dairy cooperatives is essential to dairy development in emerging economies. Within dairy value chains, however, their contributions are often not formally acknowledged or rewarded. This article contributes to filling this gap by adopting a multileveled institutional perspective to explore the case of dairy development in the Pangalengan mixed-sex dairy cooperative on West Java, Indonesia. The objective is to add evidence from the dairy development practice in Indonesia (...) to the current agenda for gender and development as well as identify pathways for future research on dairy development that will help it do better in practice. Central to the exploration is a discussion of formal and informal institutions as part of the dynamics of the inequality regimes in dairy cooperatives. Evidence from dairy development practices in the Pangalengan cooperative shows, among others, distinct differences between the participation of male and female target groups in dairy development extension, as well as farm size- and resource-related trends in ‘masculinization’ and ‘feminization’ of the smallholder farmer household. The conclusions contribute to debates on more resilient, thus sustainable working relations in food chains, women’s empowerment, gender equality and social justice in agriculture as well as cooperative studies.

Inauguration speech at chair number 18 of the Brasilian Academy of Philosophy.

There have been several attempts to identify what Aristotle holds as distinctive to magnificence. The most common interpretation is that magnificence is generosity of large wealth. Irwin proposes an alternative where magnificence is generosity applied to complicated common-good projects while Curzer’s alternative is that magnificence is heroic generosity. My position is that these three positions misinterpret Aristotle’s magnificence by explicitly or implicitly rejecting some of the claims that Aristotle makes.

This paper investigates some classical oppositional categories, like synthetic vs. analytic, posterior vs. prior, imagination vs. grammar, metaphor vs. hermeneutics, metaphysics vs. observation, innovation vs. routine, and image vs. sound, and the role they play in epistemology and philosophy of science. The epistemological framework of objective cognitive constructivism is of special interest in these investigations. Oppositional relations are formally represented using algebraic lattice structures like the cube and the hexagon of opposition, with applications in the contexts of modern color theory, (...) Kantian philosophy, Jungian psychology, and linguistics. (shrink)

The practice of physical activity (PA) contributes to the prevention of chronic diseases such as obesity, metabolic syndrome or cardiovascular diseases, being also directly related to the individual’s physical fitness. Therefore, it is necessary to measure and monitoring the levels of PA in childhood and adolescence, since it may be useful to describe their current health status and the association with physical fitness, as well as to reveal putative consequences in the future. Within the educational field, it has been shown (...) that physical education (PE) classes are a favorable context for the creation of healthy physical-sports habits and self-determined motivation could be a key for explaining the level of PA practice. For this reason, the purpose of this research was to study the mediating role of integrated regulation (IR) on the relationship between PA and physical fitness in children and adolescents. A total of 325 students between 11 and 14 years old participated in the study. The level of PA was estimated through the specific Physical Activity Questionnaire for Children (PAQ-C), while motivation and IR were measured by using the Perceived Locus of Causality scale (PLOC-2). In addition, physical fitness was measured through the Eurofit fitness battery of tests, composed of three body composition measures and seven tests of different physical capacities. The physical fitness score showed no differences when genders were compared. After regression analysis, the resulti... (shrink)

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Background:The decision whether to initiate cardiopulmonary resuscitation may sometimes be ethically complex. While studies have addressed some of these issues, along with the role of nurses in cardiopulmonary resuscitation, most have not considered the importance of nurses acting as advocates for their patients with respect to cardiopulmonary resuscitation.Research objective:To explore what the nurse’s advocacy role is in cardiopulmonary resuscitation from the perspective of patients, relatives, and health professionals in the Basque Country (Spain).Research design:An exploratory critical qualitative study was conducted from (...) October 2015 to March 2016. Thematic analysis was used to analyse the data.Participants:Four discussion groups were held: one with patients and relatives (n = 8), two with nurses (n = 7 and n = 6, respectively), and one with physicians (n = 5).Ethical considerations:Approval was obtained from the Basque Country Clinical Research Ethics Committee.Findings:Three significant themes were identified: (a) accompanying patients during end of life in a context of medical dominance, (b) maintaining the pact of silence, and (c) yielding to legal uncertainty and concerns.Discussion:The values and beliefs of the actors involved, as well as pre-established social and institutional rules reduced nurses’ advocacy to that of intermediaries between the physician and the family within the hospital environment. On the contrary, in primary health care, nurses participated more actively within the interdisciplinary team.Conclusion:This study provides key information for the improvement and empowerment for ethical nursing practice in a cardiac arrest, and provides the perspective of patients and relatives, nurses and physicians.

Conceptual congruency effects are biases induced by an irrelevant conceptual dimension of a task (e.g., location in vertical space) on the processing of another, relevant dimension (e.g., judging words’ emotional evaluation). Such effects are a central empirical pillar for recent views about how the mind/brain represents concepts. In the present paper, we show how attentional cueing (both exogenous and endogenous) to each conceptual dimension succeeds in modifying both the manifestation and the symmetry of the effect. The theoretical implications of this (...) finding are discussed. (shrink)
