Herder’s philosophical model of the learning organisationThe author describes Johann Gottfried Herder’s education philosophy and his plans for an ?alternative“ school. His ?alternative school concept“ shows how the teacher as supervisor of the learning process should take the individual needs into account and adapt the didactics and methods of teaching to these needs. This practice conforms to the rules of today’s reformed schools. Learning as an extension of subjective experiences and life possibilities requires an open organisational structure, and this is what Herder designed.  相似文献

One of the most dynamic and fruitful areas of current health‐related research concerns the various roles of the human microbiome in disease. Evidence is accumulating that interactions between substances in the environment and the microbiome can affect risks of disease, in both beneficial and adverse ways. Although most of the research has concerned the roles of diet and certain pharmaceutical agents, there is increasing interest in the possible roles of environmental chemicals. Chemical risk assessment has, to date, not included consideration of the influence of the microbiome. We suggest that failure to consider the possible roles of the microbiome could lead to significant error in risk assessment results. Our purpose in this commentary is to summarize some of the evidence supporting our hypothesis and to urge the risk assessment community to begin considering and influencing how results from microbiome‐related research could be incorporated into chemical risk assessments. An additional emphasis in our commentary concerns the distinct possibility that research on chemical–microbiome interactions will also reduce some of the significant uncertainties that accompany current risk assessments. Of particular interest is evidence suggesting that the microbiome has an influence on variability in disease risk across populations and (of particular interest to chemical risk) in animal and human responses to chemical exposure. The possible explanatory power of the microbiome regarding sources of variability could reduce what might be the most significant source of uncertainty in chemical risk assessment.  相似文献

We construct a quantitative equilibrium model with firms setting prices in a staggered fashion and use it to ask whether monetary shocks can generate business cycle fluctuations. These fluctuations include persistent movements in output along with the other defining features of business cycles, like volatile investment and smooth consumption. We assume that prices are exogenously sticky for a short time. Persistent output fluctuations require endogenous price stickiness in the sense that firms choose not to change prices much when they can do so. We find that for a wide range of parameter values, the amount of endogenous stickiness is small. Thus, we find that in a standard quantitative model, staggered price‐setting, alone, does not generate business cycle fluctuations.  相似文献

In the literature on M&A and social justice, equality is regarded as an important principle to facilitate social integration. This article debates what happens when the equality principle is operationalized; from intentions in the pre‐merger process to the distribution of resources and decision‐making rules in the post‐merger process. In a merger between two state‐owned telecoms corporations in the Scandinavian countries, we found that the principle of equality had the reverse effects on social integration to that predicted in the literature. Instead of facilitating the social integration process, the equality principle led to perceptual and structural fallacies negatively influencing social integration. We suggest that these disintegrating effects were particularly strong because this was an international merger between two state‐owned firms of unequal size.  相似文献

在19世纪晚期技术革命发生前,中国出版业的类型出现了重大变化,时间上主要是乾隆晚期、嘉庆和道光年间(1796-1850),即19世纪上半叶。在19世纪晚期"古腾堡式的机械印刷"传入上海时,机械化出现了,而在此之前正发生四种变化,它们导向的正是所谓文学现代性的后期标志。这四种变化包括小说的产量、发行方式、小说中表现的国际意识以及小说预期的读者构成。这些趋势的出现早于 19世纪晚期印刷技术革命,也早于 20世纪初期教育和文学生活中的变化。这表明在试图定义文学现代性时,必须既关注突然的外部影响或内部革命造成的因果变化的力量,也要关注连续性。  相似文献

This study sought to desribe and compare commitment structures among lesbian and gay male living-together relationships, and to develop an instrument which would measure different dimensions of commitment among gay dyads without some heterosexual biases inherent in traditional measures of interpersonal commitment. Questionnaire data collected from 32 lesbians and 50 gay males who had lived together for at least six months were factor analyzed, yielding three factors: (1) intradyadic commitment, (2) extradyadic commitment, and (3) commitment-as-trust. On all three of these indices the lesbians scored somewhat higher than did the gay males, but in fact there were surprisingly few significant differences between the gay men and the lesbians. Suggestions in the data that lesbians report somewhat less social supports and are more concerned with couple boundary maintenance, whereas gay males report somewhat more jealousy and dependency, are discussed in terms of their implications for such relationships.  相似文献

Self-rated health as a predictor of mortality has been studied primarily in large, representative populations, with relatively little progress toward understanding the information processing that individuals use to arrive at these ratings. With subsamples of National Health and Nutrition Examination Survey (NHANES) Epidemiologic Follow-up Study (NHEFS) data for respondents with circulatory system disease (N = 3,709) and respondents with no diagnosable disorders (N = 1,127) at baseline, we test the idea that individuals with experience of chronic disease of the circulatory system will have more predictive self-ratings of health than healthy individuals. Poor or fair self-rated health increased the adjusted hazard of all-cause mortality for respondents with circulatory system disease, but not for respondents who were healthy. Additional analyses confirm that poor or fair self-rated health is particularly predictive for respondents with self-reported history of circulatory system diagnoses and perception of symptoms, but not for respondents without symptoms or diagnoses prior to the NHANES physical exam.  相似文献

This quantitative study investigated the ethical decision-making process of 177 Missouri members of the American Association for Marriage and Family Therapy using two in-session duty-to-warn scenarios of child abuse and HIV transmission. The components of the critical-evaluative level of ethical decision making include the lower-level decision components of personal/therapeutic response, professional ethics, and legal considerations/laws of the State, and the components of the higher-level decision base, the meta-ethical principles, which are nonmaleficence, autonomy, beneficence, fidelity, and justice. Statistical results indicated that in the child abuse scenario, professional ethics and legal considerations/laws of the State were considered most important, whereas in the HIV scenario, professional ethics were the preferred lower-level decision base. Across scenarios, the preferred higher-level decision base was nonmaleficence. There were differences across the child abuse and HIV scenarios in the perceived significance of the remaining lower-level decision base items as well as differences in perceived significance and ordering of the remaining meta-ethical principles. Limitations are discussed.  相似文献
