The need to find an intrinsic characterization of what makes a relation between events causal arises not only in local theories of causation like Salmon's process theory but also in global approaches like Lewis' counterfactual theory. According to the localist intuition, whether a process connecting two events is causal should depend only on what goes on between the events, not on conditions that hold elsewhere in the world. If such intrinsic characterizations could be found, an identification of the causal relation in the actual world (though not in other possible worlds) with physical processes may be feasible (the a posteriori identification). I consider recent proposals made for intrinsic characterizations of causality and conclude that none of them is able to deliver the intended result. 相似文献

Few data are available on alcohol experiences among elementary school children, although early onset and trying of alcohol use is known to be a risk factor for adolescent alcohol abuse. Until now, research leaves open the question on which factors encourage early trying behavior. In a cross-sectional study design, a written survey was conducted in 49 randomly selected elementary schools in Germany. The survey was carried out among 3rd and 4th graders with a median age of 9 years during class time in the school year 2010/2011. 1806 questionnaires were included in the study. The risk behavior of having tried alcohol was analyzed. A total of 37.7% (n = 681) of all children reported to have already tried alcohol. While grade and age had no significant influence in the final multivariate model, the gender effect stayed relevant (Male: aOR 1.2, 95%-CI 1.0–1.5), as did the question of whether the child liked going to school (No: aOR 1.4, 95%-CI 1.1–1.7), a lack of parental monitoring (aOR 1.5, 95%-CI 1.1–2.1), consistent parenting (Sometimes/never: aOR 1.5, 95%-CI 1.1–1.9), a regularly provided break-time snack (No: aOR 2.2, 95%-CI 1.3–3.8), as well as parents’ drinking (Yes: aOR 2.0, 95%-CI 1.6–2.6) and drinking among peers (Yes: aOR 8.5, 95%-CI 6.2–11.6). Our study shows that alcohol experiences can be highly prevalent among 3rd and 4th grade elementary school children in Germany. Our findings suggest that especially those variables which may be controlled by the parents are strongly associated with children’s alcohol experiences suggesting a starting point for preventative intervention measures. The results also indicate the need for innovative gender-sensitive approaches in the living environment of elementary school children. 相似文献

This paper explicates two notions of emergencewhich are based on two ways of distinguishinglevels of properties for dynamical systems.Once the levels are defined, the strategies ofcharacterizing the relation of higher level to lower levelproperties as diachronic and synchronic emergenceare the same. In each case, the higher level properties aresaid to be emergent if they are novel or irreducible with respect to the lower level properties. Novelty andirreducibility are given precise meanings in terms of the effectsthat the change of a bifurcation or perturbation parameterin the system has. (The same strategy can be applied to otherways of separating levels of properties, like themicro/macro distinction.)The notions of emergence developed here are notions of emergencein a weak sense: the higher level emergent properties wecapture are always structural properties (or are realized insuch properties), that is, they are defined in terms of the lowerlevel properties and their relations. Diachronic and synchronicemergent properties are distinctions within thecategory of structural properties. 相似文献

This article analyzes a type of experiment, very popular in 18th-century natural philosophy, which has apparently not led to insights into nature but which was aesthetically especially attractive. These experiments--"mimetic experiments"--allow us to trace a connection between aesthetic appreciation in science and in art contemporaneous with the science. I use this case as a problem for McAllister's theory of aesthetic induction according to which aesthetic standards in science tend to be associated with empirical success and propose an alternative mechanism that is able to account for the natural philosophers' predilection for unsuccessful but beautiful experiments. 相似文献
