Motivated by the definition of semi-Nelson algebras, a propositional calculus called semi-intuitionistic logic with strong negation is introduced and proved to be complete with respect to that class of algebras. An axiomatic extension is proved to have as algebraic semantics the class of Nelson algebras. 相似文献

Various authors within the contemporary debate on divine action in nature and contemporary science argue both for and against a Thomistic account of divine action through the notions of primary and secondary causes. In this paper I argue that those who support a Thomistic account of divine action often fail to explain Aquinas' doctrine in full, while those who argue against it base their objections on an incomplete knowledge of this doctrine, or identify it with Austin Farrer's doctrine of double agency – again failing to do Aquinas justice. I analyse these objections, indicating how they do not address Aquinas' doctrine by offering a brief but full account of the latter. 相似文献

How migration influences the processes of identity development has been under longstanding scrutiny in the social sciences. Usually, stage models have been suggested, and different strategies for acculturation (e.g., integration, assimilation, separation, and marginalization) have been considered as ways to make sense of the psychological transformations of migrants as a group. On an individual level, however, identity development is a more complex endeavor: Identity does not just develop by itself, but is constructed as an ongoing process. To capture these processes, we will look at different aspects of migration and asylum seeking; for example, the cultural-specific values and expectations of the hosting (European) countries (e.g., as identifier), but also of the arriving individuals/groups (e.g., identified as refugees). Since the two may contradict each other, negotiations between identities claims and identity assignments become necessary. Ways to solve these contradictions are discussed, with a special focus on the experienced (and often missing) agency in different settings upon arrival in a new country. In addition, it will be shown how sudden events (e.g., 9/11, the Charlie Hebdo attack) may challenge identity processes in different ways. 相似文献

The atomic hypothesis according to Ludwig Boltzmann. The scientific and philosophical importance of a controversial position
at the close of the 19th century. This paper examines Boltzmann’s standpoint in the controversy over the existence of atoms between himself on the one hand
and Mach, Ostwald, Helm and to some extent Duhem on the other hand. The latter wanted to develop a physics only constructed
with perceptible phenomena. Because of the lack of empirical evidence of the atoms at that time they did not accept them for
the construction of physics. In contrast, Boltzmann found the acceptance of atoms to be a fruitful assumption, since for him
the construction of physics required going beyond perceptible phenomena. Two different conceptions of nature and of the ways
to know nature clashed in this disagreement between Boltzmann and his opponents. Op-posing one-sided positions, Boltzmann
supported the hypothetical character of science, in which more than one basic hypothesis can be advanced: he was open to the
possibility of fundamental revolutions in science.

The relationship between open-field ambulation and intracranial self-stimulation (ICSS) at the lateral hypothalamic area was studied in rats. A treatment with i.p. saline of d-amphetamine was also applied to the animals prior to ICSS tests. High-ambulatory rats (comparable to human extraverts) showed an equally higher susceptibility to ICSS reward than low-ambulatory rats (comparable to human introverts) with both saline and amphetamine. These findings were interpreted comsidering the ICSS as a strong stimulation which would tend to produce ‘unconditioned inhibition’ much earlier in low-ambulatory rats than high-ambulatory rats thus leading to a better conditioning among the high-ambulatory Ss. 相似文献

This paper reports a study comparing the memorability of information that either confirmed, disconfirmed, or was irrelevant to, particular real-life social group stereotypes. Memory for both stereotype-confirming and stereotype-disconfirming material was enhanced relative to that for material which was stereotype-irrelevant. Further, there were no differences between the memory for stereotype-confirming and -disconfirming information. Implications for stereotype stability and change are noted. 相似文献

This research examined contributions of loss events to loss distress and trauma symptoms (accounting for trauma events) for refugee women at risk. Participants (N?=?104) responded to the Multidimensional Loss Scale (loss events and distress) and Harvard Trauma Questionnaire (trauma events and symptoms). Loss events contributed uniquely to loss distress (explaining additional 50.8% variance), and made a unique contribution to trauma symptoms (explaining additional 5.2% variance) approximately equal to trauma events. Appropriate response to psychic distress in refugee women at risk requires assessment of both loss and trauma and consideration of cultural differences in ways loss is expressed and meaning ascribed to symptoms. 相似文献

A community survey in 4,426 adults was undertaken as part of the World Mental Health Survey Initiative reporting the prevalence and risk factors for suicide‐related outcomes in Colombia. Lifetime prevalence estimates of suicide ideation, plans, attempts, and risk factors for suicide‐related outcomes were assessed. Retrospective reports of disorders age‐of‐onset were used to study associations between primary mental disorders and first onset of suicide‐related outcomes. Risks of plans and attempts were highest with ideation early age‐of‐onset and within the first year. The highest risk for ideation and attempt among ideators occurred in the 18–29 age group. After first employment (defined as the first paid job accepted by the respondent) and presence of mental disorders constituted risk factors. Impulse‐control disorders were strongest diagnostic predictors. 相似文献
