Formulating Hypotheses Graphically in Social Research 总被引:1,自引:0,他引:1
This article explores the proposition that the appropriate use of suitable forms of graphic communication can improve the formulation and presentation of hypotheses in quantitative social science research. The creative nature of scientific diagrams is discussed and the technological advances in computer graphic media are seen as part of a visual revolution which is markedly changing not only the way we see things but also the way we think and do things today. Brief historical views on the use of hypotheses and diagrammatic languages in science are given. The restricted use of graphic communication tools in social research academic documents is discussed and the importance of using well-designed data graphics in the production and transmission of scientific knowledge is highlighted. Hypotheses are conceptualised and their importance within social research is emphasised. A methodological approach for formulating hypotheses graphically is proposed based on the use of three types of language: notation, statement (ordinary language) and diagram. Some criteria are suggested for the selection of diagram type dependent on the related variables. Several examples are given covering the different models proposed. 相似文献

A recent empirical literature has addressed the relationship between income and religion, but most of the studies are based on microdata. Macroeconomic analysis of the issue has largely ignored the potential heterogeneity between countries. Using retrospective data on church attendance rates for a panel of countries between 1925 and 1990, we apply heterogeneous panel data estimators and reveal that the effect of participation in religious activities on income per capita is mostly non-significant. This is consistent with some of the recent research that casts doubt onto the influence of religion on income, once causality is taken into account. 相似文献

This paper shows how relevant concepts in educational effectiveness can support public policy in order to improve the performance
of educational systems. Specifically, value-added indicators and the property of their stability over time is addressed with
reference to application to school/teacher improvement. Findings of a longitudinal study developed in Portugal concerning
primary education in mathematics are presented. Variance component models are fitted in order to obtain those indicators yearly
to class-school units. Results of this study reveal that value-added indicators can be a useful instrument for progressive
improvement in education, particularly in countries with high rates of student retention and evasion. The novelty of this
paper is to measure value added over a single year rather than all stage of schooling that refers to more than 1 year. 相似文献

Large corporations have been using derivative instruments as a tool to protect their indirect exposure, as FX risks. A sample with 47 non-financial Bovespa Listed Brazilian companies from 2004 and 2010 was used to test the hypothesis that use of derivatives as a risk management policy tool reduces companies' cost of capital. In contrast to other countries, results rejected this hypothesis, showing that in Brazil there is a positive relationship between using these tools and cost of capital. However, a more in-depth analysis based on the TACC model for a Brazilian company, this hypothesis was not rejected after the 2008 crisis. 相似文献

The relationship between social and financial performance (CSP – FP) has been a main objective in the literature on business
management, as it would provide an economic justification for the social investment insofar as it contributes to the creation
of value. This relationship has been empirically tested by several authors though without using a theoretical model that sustains
this relationship. The aim of this article is to propose a theoretical model of the process of the creation of value from
the reputation generated by companies, integrating the factors that have been shown to be more relevant in this process from
previous research, in such a way that hypotheses are put forward regarding the existence of this relationship and the factors
that determine it. Finally, an empirical test is performed using the 100 most prestigious companies operating in Spain during
2004. 相似文献

In this paper we offer insights about the type of societies that are more likely to generate and promote innovation. In particular, we present results from a study of innovation through computational social simulations to focus on a structural aspect of societies: their degree of separation and how this social characteristic may be related to what, how and why new ideas and solutions can replace existing wide-spread practices in a society. We focus on the work of design practitioners and sustainable design as an example to illustrate these insights. 相似文献
