This two-part article examines the competition between the clonal selection theory and the instructive theory of the immune response from 1957–1967. In Part I the concept of a temporally extended theory is introduced, which requires attention to the hitherto largely ignored issue of theory individuation. Factors which influence the acceptability of such an extended theory at different temporal points are also embedded in a Bayesian framework, which is shown to provide a rational account of belief change in science. In Part II these factors, as elaborated in the Bayesian framework, are applied to the case of the success of the clonal selection theory and the failure of the instructive theory. 相似文献

In this paper I argue that Frank Jackson’s Knowledge Argument is better considered not as an argument against physicalism,
but as an argument that objective theories must be incomplete. I argue that despite the apparent diversity of responses to
the knowledge argument, they all boil down to a response according to which genuine epistemic gains are made when an individual
has an experience. I call this the acquaintance response. I then argue that this response violates an intuitive stricture
on the objectivity of theories. Therefore, the knowledge argument does show that objective theories cannot provide a complete
understanding of the world. The result, however, is that both objective dualism and objective physicalism are refuted by the
argument. In the end it is suggested that the notion of “subjective physicalism” is one that should be pursued. 相似文献

Several recent studies have shown that focus structural representations influence syntactic processing during reading, while other studies have shown that implicit prosody plays an important role in the understanding of written language. Up until now, the relationship between these two processes has been mostly disregarded. The present study disentangles the roles of focus structure and accent placement in reading by reporting event-related brain potential (ERP) data on the processing of contrastive ellipses. The results reveal a positive-going waveform (350-1300 ms) that correlates with focus structural processing and a negativity (450-650 ms) interpreted as the correlate of implicit prosodic processing. The results suggest that the assignment of focus as well as accent placement are obligatory processes during reading. 相似文献

Singapore is an urban, highly industrialized country in South East Asia. By 2030, one-fifth of the population is projected to be composed of citizens aged above 65 years. Research on aging has largely focused on the effects of deteriorating physical ability on daily functioning capabilities (Iwarsson & Isacsson, 1997; Warr, 1995). More recently, the role of self-perceived usefulness, competence and control on well-being in the elderly have been investigated (Heberlein, Licht & Licht, 1999; Ranzjin, Keeves, Luszcz, & Feather, 1998). In other fields, activity and involvement have been identified as effective coping devices (Nair, 1989; Shalit, 1988). The present study compared the conceptual understanding of the esteem and well-being of the elderly on the dimensions of activity, involvement, and control, as viewed by an undergraduate sample (n = 60) and a cross-section of seniors (n = 71). Three separate factor analyses reflected interesting variations in the conceptual frameworks. 相似文献

A case study of six teachers cooperating to improve a teacher’s teaching showed the dynamics of the group problem-solving
process. An analysis of their verbal interactions showed the importance of shared understanding to successful group problem
solving. The cooperative group structure helped members resolve cognitive conflicts and build group understanding. During
this process, the members’ past teaching experiences and knowledge contributed to their conceptualization of the teacher’s
teaching problems and their proposed solutions to improve the teacher’s teaching.
Tsz Cheung Lam graduated from the Department of Educational Psychology at the Chinese University of Hong Kong in 2004 and obtained his Master
of Education degree. His research interests lie primarily on cooperative learning and problem solving. As a primary school
teacher in practice, he is now studying part-time for another master degree in data science at the Department of Statistics
of the Chinese University of Hong Kong. 相似文献

The General Health Questionnaire (GHQ) is a self-report questionnaire designed to identify psychological distress. Psychometric properties of two versions of GHQ-12 and GHQ-20 were assessed in a large population-based sample of Finnish twins, ages 22 to 27 (n= 4580). Participants were randomized into two subgroups, namely Twin1 (n= 2294) and Twin2 (n= 2286). The GHQ-12 data were assessed using Confirmatory Factor Analysis (CFA). The factor structure of the GHQ-20 was first assessed with Exploratory Factor Analysis (EFA) in the Twin1 dataset, and the results obtained were then subjected to CFA in Twin1 and Twin2 datasets. The CFA of the GHQ-12 indicated that the best fit and the simplest solution were provided by the three-factor solution in both subpopulations. Analyses of the GHQ-20 suggested that the four-factor structure was superior to the three-factor model. This result is also theoretically justifiable. Compared to the 12-item version, GHQ-20 provides additional fourth factor of anhedonia, suggesting some discriminative power. 相似文献

An empirical test of a comprehensive model of intrapersonal empowerment in the workplace 总被引:9,自引:0,他引:9
Gretchen M. Spreitzer 《American journal of community psychology》1995,23(5):601-629
A comprehensive model of intrapersonal empowerment in the workplace posits that empowerment mediates the relationship between
the social structural context and behavioral outcomes. The social structural context is operationalized as perceptions of
role ambiguity, sociopolitical support, access to strategic information and resources, and work unit culture, whereas behavioral
outcomes are operationalized as innovativeness and effectiveness. The model is examined on a sample of 324 middle managers
from different units of a Fortune 50 organization. Survey data are examined using a series of regression analyses to assess
the mediating effect of intrapersonal. Results suggest that intrapersonal empowerment mediates the relationship between some
elements of workplace social structure and innovativeness, but not effectiveness. Although not a mediating mechanism for effectiveness,
intrapersonal empowerment is nonetheless directly related to effectiveness (as assessed by the respondent's subordinates).
Implications of the results are discussed as are study limitations and directions for future research.
This paper is based on the author's dissertation, presented in partial fulfillment of the requirement for the doctoral degree
at the University of Michigan. I am grateful to my dissertation committee which included Robert E. Quinn (chair), Susan Ashford,
Richard Bagozzi, Karl Weick, and Marc Zimmerman for their thoughtful guidance. Thanks is also extended to Neil Sendelbach

AbstractBelief normativism is roughly the view that judgments about beliefs are normative judgments. Kathrin Glüer and Åsa Wikforss (G&W) suggest that there are two ways one could defend this view: by appeal to what might be called ‘truth-norms’, or by appeal to what might be called ‘norms of rationality’ or ‘epistemic norms’. According to G&W, whichever way the normativist takes, she ends up being unable to account for the idea that the norms in question would guide belief formation. Plausibly, if belief normativism were true, the relevant norms would have to offer such guidance. I argue that G&W’s case against belief normativism is not successful. In section 1, I defend the idea that truth-norms can guide belief formation indirectly via epistemic norms. In section 2, I outline an account of how the epistemic norms might guide belief. Interestingly, this account may involve a commitment to a certain kind of expressivist view concerning judgments about epistemic norms. 相似文献
