Zusammenfassung Ein z?hlender Chronograph1) wird beschrieben, der Reihen von fortlaufenden und sich überschneidenden Zeitstrecken zu messen gestattet und der ein rasches
Bestimmen und nachtr?gliches Kontrollieren der gemessenen Zeiten erlaubt.
Es werden Hundertstel-, Zehntel-, halbe und ganze Sekunden (bei Umstellen auf “langsamen Gang” Zehntel- und ganze Sekunden)
in unterschiedlicher Weise auf einem Morsestreifen kenntlich gemacht, und zwar durch ein Gangwerk, das von einer Stimmgabel
reguliert wird und im hohen Grade unabh?ngig von Schwankungen des Motors ist, der den Chronographen antreibt. Die zu messenden
Zeiten werden durch zwei R?dchenschreiber als L?ngsstriche auf dem Morsepapier wiedergegeben.

We prove that there are two involutions defined by monadic terms that characterize Monadic Algebras. We further prove that the variety of Monadic Algebras is the smallest variety of Interior Algebras where these involutions give rise to an interpretation from the variety of Bounded Distributive Lattices into it.Research funded by Fondecyt, project N 764-1987. 相似文献

The difference in process and outcome of two therapies conducted by the author with families having a psychotic adolescent is considered. Attention is paid to the fact that in one case the client was regarded theoretically as an opponent and in the other as a partner. It is concluded that the contention thatthe therapist must decide whether to be influential or cooperative arises from a logical confusion by failing to recognize that therapy cannot be anything other than cooperation.Originally published as part of a special issue on the power metaphor guestedited by Klaus G. Deissler inZeitschrift fur systemische Therapie (1986),4, 253–257. Translated by S. Awodey. 相似文献

Summary We have seen that the theory of the evolution of the universe is very remote from being matter of absolute knowledge as its popular presentation today would have us believe. Moreover, it is based on a certain aspect of reality, namely, that of science, which cannot pretend to be the only one possible and thus to exclude the religious aspect of the world as a creation by God. The same is true regarding the evolutionary theories of life by Eigen or Vollmert, both being based on polymeric chemistry. If, therefore, Vollmert confesses, as already quoted, that he is not afraid to accept a creating God as an alternative to Darwinism, so in this respect he speaks despite everything as a believer and not as a scientist. By no means do I deny that the scientific results of Vollmert which seem to reveal the mystery of life to us can strengthen our faith — but never can faith be based on it. Faith springs from another source.Despite that, we can say today that the situation has changed principally, because both the philosophy of science and the discussions of the theories of evolution have shaken that kind of naive belief in science which in contrast to former times has turned theology into the ancilla, the maid of science.On the other hand, it would be a great misunderstanding to assume that now we can simply turn the tables. The criticism which I have partly put forward against the modern theories of evolution cannot obscure the numerous discoveries of the highest importance which are connected with them. These discoveries have provided us with an immensely deepened knowledge both of the physical conditions of the universe and of the chemical foundations of life. To conclude, I want to quote an American scientist who said: I am as confused as before — but on a much higher level. And this, I think, is the best summary of the present situation. 相似文献

This article focuses on gender differences in early heterosexual behaviour among Norwegian adolescents. The material comprised a random sample of 3000 Norwegian adolescents aged 17–19 years. The response rate was 63%. Data were collected by means of anonymous self-administered questionnaires. Sixty-nine per cent of the girls and 59% of the boys had had sexual intercourse. The majority of the adolescents, and a larger percentage of girls than of boys, had their first intercourse within a relationship of mutual commitment. The boys' first coital partners were 0.2 years younger than the boys themselves and the girls' partners were 2.8 years older than were the girls. Boys had had more coital partners than girls but girls had had intercourse more often than boys. Coital frequency was affected more by how long the adolescents had known the partner than by gender as such. In conclusion, boys and girls aged between 17 and 19 years form part of couples at two different stages of development. For this reason, boys and girls accumulate different sexual experiences in the early stage of their sexual careers. 相似文献

This study investigated the effectiveness of using visual cues to highlight the seams of baseballs to improve the hitting of curveballs. Five undergraduate varsity baseball team candidates served as subjects. Behavior change was assessed through an alternating treatments design involving unmarked balls and two treatment conditions that included baseballs with 1/4-in. and 1/8-in. orange stripes marking the seams of the baseballs. Results indicated that subjects hit a greater percentage of marked than unmarked balls. These results suggest that the addition of visual cues may be a significant and beneficial technique to enhance hitting performance. Further research is suggested regarding the training procedures, effect of feedback, rate of fading cues, generalization to live pitching, and generalization to other types of pitches. 相似文献
