Content analysis is a very tedious method of data collection. This paper addresses once more the question of whether and how computers may be used to facilitate content analysis in the coding stage. To interpret natural language automatically a computer program must be able to unravel the syntactical structure of sentences (‘parsing’) and to trace their semantical meaning by dealing with textual context (= ‘co-text’), prior knowledge (context outside the text) and semantic variability (different or ambiguous meanings of words and phrases). Several approaches to enable computer programs to perform these tasks are discussed, including approaches from the fields of cognitive psychology and artificial intelligence. The conclusion should be that it is still impossible to enable computer programs to perform all these tasks. But there are possibilities for using computer programs to support human coders both in the coding stage and the data-analysis stage of content analysis. As an example the program CETA to perform Computer-aided Evaluative Textual Analysis is discussed. 相似文献

This article suggests one way to systematically code textual data for research. The approach utilizes computer content analysis to examine patterns of emphasized ideas in text as well as the social context or underlying perspective reflected in the text. A conceptual dictionary is used to organize word meanings. An extensive profile of word meanings is used to characterize and discriminate social contexts. Social contexts are analyzed in relation to four reference dimensions (traditional, practical, emotional and analytic) which are used in the social science literature. The approach is illustrated with five widely varying texts, analyzed with selected comparative data. This approach has been useful in many social science investigations to system-atically score open-ended textual information. Scores can be incorporated into quantitative analysis with other data, used as a guide to qualitative studies, and to help integrate strengths of quantitative and qualitative approaches to research. 相似文献

Content analysis as a methodology of data collection from text sources is very labor intensive and therefore costly. Advances in computer-assisted content analysis have greatly increased the power of the methodology. But, even in a computer environment, complex searches require extensive prior manipulation of the original text in order to assign to it a basic structure. It is this structure that allows researchers to perform complex queries in highly general ways. I argue that Semantics provides powerful templates for structuring text data (text grammars) and other conceptual tools that can be profitably used to increase the efficiency of content analysis projects (e.g. news schema and macro propositions). More generally, I argue that efficiency in content analysis projects depends upon such characteristics as (1) organization of the coding task; (2) newspaper reporting practices. The discussion of these characteristics results in several suggestions on how to increase the efficiency of the methodology. 相似文献

This paper adapts a widespread formalism of Knowledge Representation known in the AI literature as J. Sowa'sConceptual Graphs to the purposes of Content Analysis. It is proposed that instead of nested contexts, negation and modalities could be represented by colouring the links and the nodes of the graphs. This colour-based representation of logic enables the replacement of Sowa's game-theoretical semantics by a matching algorithm. It is also claimed that the resulting local application of negation and modalities is close to the behaviour of negation and adverbs in natural language. Above all, the use of colours restores a unique level in semantic networks. These flat semantic networks are appealing to social scientists because they avoid information redundancy and improve connectivity in the network. Two methods of textual analysis that can take direct benefit from semantic networks (semantic paths distributions and texts clustering) are presented. However, flat semantic networks that remain semantically correct are perhaps even more interesting because they may bridge standard networks with connectionnist networks. In such a perspective, Coloured Conceptual Graphs represent an intermediate but promising step. 相似文献

This paper focuses on the strategic design of expatriates' salaries. Unlike standard expatriation literature that assumes a lack of connection between strategy and international managers' compensation, we use the theoretical concepts from the international strategic management research to discuss how different international strategies affect the way expatriates are compensated. In this respect, the paper proposes a series of hypotheses on how expatriate compensation systems take shape according to the role that the expatriates may play in the internationalization process. The hypotheses refer to the type of incentives offered to encourage acceptance of the assignment, the type of criteria used to evaluate their performance and the reference unit used to establish variable compensation. 相似文献

The existing literature on the subsidy-efficiency nexus is almost exclusively based on static modelling and thus ignores the inter-temporal nature of production decisions. The present paper contributes to this literature by developing a dynamic stochastic frontier model, which is then estimated using a sample of French farms over the period 1992–2011. For comparison purposes, the static counterpart of the dynamic model is also estimated. The results indicate that, in the dynamic case as well as in the static one, public subsidies are negatively associated with farm technical efficiency. Nevertheless, these linkages are found to be weak, and they are much weaker when dynamic aspects are taken into account. 相似文献

Establishing adequacy of psychometric properties of an instrument involves acquisition and evaluation of evidence based on item content and internal structure. Content validity evidence consists of subject matter experts providing quantitative ratings of the extent to which items are a representative sample of targeted domain. Evidence of internal structure includes factor analytic studies and examination of item interrelationships based on item responses from participants. Although subject matter expert ratings and participant response data are traditionally analyzed separately, each serves to inform the other in important ways. We propose integrating subject matter experts’ and participants’ data seamlessly to establish a unified model of validity evidence. The approach is applied to an instrument designed to measure nursing home culture change (i.e., resident-centered care). The proposed method has been demonstrated to be useful with a posterior distribution resulting in stable estimates of psychometric parameters superior to traditional analytic approaches. To illustrate the efficacy of the methodology, we present a simulation study and discuss its place in psychometric methods. 相似文献

Final demand purchases initiate production processes that ultimately lead to environmental impacts. With the increase in international trade, many production processes occur outside of the country of final consumption. Whilst several studies have evaluated the pollution embodied in consumption and trade flows, few studies have investigated the structural linkages between domestic consumption and production in foreign regions. In this article we apply three complementary approaches to study the production network leading from the Norwegian economy to domestic and international environmental impacts: (1) the consumption perspective identifies final demand purchases that produce environmental impacts; (2) the production perspective identifies the production processes generating the pollution for a given demand; and (3) structural path analysis is used to provide the linkages between the global production networks linking consumption and production. We find that the three approaches provide different, but complementary information. For policy to focus on both sustainable consumption and production, all three approaches are required to fully identify environmentally important sectors in an economy. 相似文献
