Seventy European American families with 6-month-old infants participated in this investigation of current parenting roles. Parental reports and observations revealed that mothers were more involved with the infants and fathers were employed outside the home more hours per week than mothers. Both parents rated the mother as a better caretaker of the infant than the father. The mother rated the father's caretaking abilities higher than he rated himself. In concordance with previous research, maternal concerns about separations related to employment were found to be influenced by maternal employment factors. Paternal concerns about separations related to employment were also influenced by maternal employment factors. Changes in parenting roles were discussed. 相似文献

This paper presents two experiments to support the general hypothesis that the coordination of actions between individuals promotes the acquisition of cognitive coordinations. The first experiment shows that two children, working together, can successfully perform a task involving spatial coordinations; children of the same age, working alone, are not capable of performing the task. The second experiment shows that subjects who did not possess certain cognitive operations involved in Piaget's conservation of liquids task acquire these operations after having actualized them in a social coordination task. 相似文献

A previous experiment (Doise, Mugny and Perret-Clermont, 1975) has shown that pairs of subjects perform better on a spatial representation task than subjects alone. As a conclusion the hypothesis was put forward that conflicts of cognitive centrations, embedded in a social situation, lead children to coordinate their centrations. The present research was planned to verify several predictions following from this general hypothesis. Results show that indeed more progress takes place when children with different cognitive strategies work together than when children with the same strategies do so, and that not only the less advanced but also the more advanced child progresses when they interact with each other. 相似文献

Two questionnaire studies were conducted (N=80 and N=175) to examine the structure and the social anchoring of the organizing principles of personal and governmental involvement concerning human rights. The results indicated that these organizing principles had, as hypothesized one abstract and one applied dimension. The second study evaluated the correlations between these dimensions and values. Results were consistent with Schwartz's (1992) model predicting both the internal structure of values and their relations with other variables. Amongst other results, self-transcendence values were positively correlated with the abstract involvements and the applied personal involvement, and negatively with the applied governmental involvement. The results concerning the correlations between conservation values and the four organizing principles were the opposite. Results concerning the links between different levels of social anchorings, particularly between the value types and variables such as religious affiliation and practice political preferences, and social and political activism were also presented and discussed. © 1998 John Wiley & Sons, Ltd. 相似文献

Pour résoudre les paradoxes bien connus de la mécanique quantique, on propose une interprétation par ramification (ou univers parallèles) analogue à celle d’Everett, mais avec des différences: (i) on propose une infinité continue de branches, dont les poids (o[ugrave] probabilités) se calculent par intégrale; (ii) les branches sont séparées par des ramifieurs qui se propagent à la vitesse de la lumière. Lorsqu’est négligeable la composante d’énergie négative de la fonction d’onde, le poids de chaque branche en un point donné u est égal au flux du quadrivecteur (courant-densité de présence), soit à travers l'élément d’écran antérieur à u sur lequel l'impact est perçu, soit à travers le cône passé de u si aucun impact n’est perçu. In order to solve well-known paradoxes in quantum mechanics, we propose a reworking of Everett's interpretation with ramified branches (or many worlds), yet somewhat different: (i) branches form an infinity continuum and each weight (probability) is defined by an integral; (ii) branches are separated by ramifiers which propagate themselves with the velocity of light. Assuming we can neglect the negative-energy component in the wave function, then the weight of each branch at a given point u is equal to the flux of the quadrivector (current-presence density), either through the screen element where the impact occurs, or through the past light-cone of u if no impact occurs. 相似文献

In this paper, we trace the conceptual history of the term ‘metamathematics’ in the nineteenth century. It is well known that Hilbert introduced the term for his proof-theoretic enterprise in about 1922. But he was verifiably inspired by an earlier usage of the phrase in the 1870s. After outlining Hilbert's understanding of the term, we will explore the lines of inducement and elucidate the different meanings of ‘metamathematics’ in the final decades of the nineteenth century. Finally, we will investigate the earlier occurrences and come to the conclusion that the conceptual prehistory of the Hilbertian notion of metamathematics dates back to 1870, whereas the history of the word starts in 1799 at the latest.
