Correlational analyses are one of the most popular quantitative methods, yet also one of the mostly frequently misused methods
in social and behavioral research, especially when analyzing ordinal data from Likert or other rating scales. Although several
correlational analysis options have been developed for ordinal data, there seems to be a lack of didactically written literature
illustrating the appropriate use and differences among them. The purpose of this paper is to provide a synthesis of correlational
analysis options when analyzing ordinal data. These options span from the traditional methods, such as Pearson’s r, to more recent developments, such as Bayesian estimation of polychoric correlations. An illustration of these methods utilizing
a contemporary dataset is provided. 相似文献

Assessing cultural values: developing an attitudinal scale 总被引:1,自引:0,他引:1
Effective measurement of cultural value is often elusive because of its multidimensional nature. It is also influenced by
sociodemographic characteristics (manifest variables) and attitudinal characteristics (latent variables) of populations. While
the former is easily available to researchers, the latter has not been fully studied. This paper suggests the use of a cultural
worldview scale that was developed to measure cultural attitudes of people, using factor and cluster analysis. Four factors
comprise the scale: cultural linkages, recognition of cultural values, cultural loss and preservation of traditions and customs.
Some advantages of using this scale are demonstrated, and relationships with sociodemographic variables are investigated.
Managerial and policy implications are discussed.

On the basis of their cognitive abilities, children with Asperger syndrome are attractive candidates for inclusive education and, in Australia, most are in integrated settings. However, social interaction between children with Asperger syndrome and their peers remains problematic, with the children with Asperger syndrome often being left alone despite being among or near classmates. For classroom teachers, effective interventions in terms of class management are critical to facilitate positive social interaction between these two groups of children, and case studies can tell us a great deal about what works. In practice, a combination of intervention techniques may be best, in case a single one is ineffective, and in order to take advantage of potential synergies. In this article, Serene Choi, of the School of Education at the University of Newcastle (Australia) and Timo Nieminen, of the Centre for Biophotonics and Laser Science in the Department of Physics at the University of Queensland, report a naturalistic multiple-component intervention used to develop the social skills of a boy with Asperger syndrome in a mainstream school in Australia. This combined intervention, making use of social stories, simple peer modelling and individual lessons, appears to be a practical teaching method for inclusive education. 相似文献

Effects of student motivation on performance in Web-based instruction (WBI) were examined. In particular, applicability of the self-efficacy theory to WBI contexts was tested. A total of 152 junior high school students in Seoul, Korea, participated in WBI during regular science classes. Participants completed motivational surveys before the onset of WBI and took the written and search tests at the end of WBI. Path analyses revealed that students' self-efficacy for self-regulated learning positively related to their academic self-efficacy, strategy use, and Internet self-efficacy. Academic self-efficacy predicted students' performance on the written test, which comprised problems on topics covered during the previous WBI sessions. Students' scores on the WBI search test were significantly and positively predicted by their self-efficacy in using the Internet. More interesting, students' academic self-efficacy beliefs were not able to predict their search test performance, whereas students' Internet self-efficacy beliefs were not able to predict their written test performance.This research is based on data collected as part of Ha-Jeen Choi's master's thesis completed at Ewha Womans University.The authors thank Steven Ross and three anonymous reviewers for their helpful comments on earlier versions of this article. 相似文献

This article extends socioemotional selectivity theory to online social networking by examining age differences in the size and composition of Facebook networks across a wide age range of Facebook users (18 to 93 years old) in a nationally representative sample. Findings suggest increasing selectivity of Facebook social partners with age. Compared to younger adults, friend networks of older adults are smaller but contain a greater proportion of individuals who are considered to be actual friends. Moreover, a higher proportion of actual to total Facebook friends is associated with lower levels of social isolation and loneliness across the life span. 相似文献

Assessing reflective thinking in solving design problems: The development of a questionnaire 下载免费PDF全文

Reflection is a critical factor in solving design problems. Using good methods to observe designers' reflection is essential to inform the design of the learning environments that support the development of design problem‐solving skills. In this study, we have developed and validated a novel self‐reporting questionnaire as an efficient instrument to explore reflection, called Assessing Reflective Thinking in Solving Design Problems (ARTiD). This questionnaire has been developed based on the three‐dimensional model for reflective thinking: the timing, the objects and the levels of reflection. A total of 294 undergraduate and graduate students in the fields of engineering, computer science and instructional design were recruited to participate in one of four iterative, formative tests through which reliability and validity analyses were performed to revise and confirm the questionnaire. Examples of participants' reflection patterns were demonstrated to show the practical value of this questionnaire. In conclusion, the final version of ARTiD was presented as a valid instrument to explore students' reflection for research and educational practice. In addition, we found that ARTiD can be used as an effective learning tool to guide student designers' reflections toward better learning and performance. 相似文献

To analyze the jamming and unjamming transition of oil-in-water emulsions under continuous temperature change, we simulated an emulsion system whose critical volume fraction was 0.3, which was validated with experimental results under oscillatory shear stress. In addition, we calculated the elastic modulus using the phase lag between strain and stress. Through heating and cooling, the emulsion experienced unjamming and jamming. A phenomenon—which is when the elastic modulus does not reach the expected value at the isothermal system—occurred when the emulsion system was cooled. We determined that this phenomenon was caused by the frequency being faster than the relaxation of the deformed droplets. We justified the relation between the frequency and relaxation by simulating the frequency dependency of the difference between the elastic modulus when cooled and the expected value at the same temperature. 相似文献

The Asian Games have exercised an influence over the Asian region which has been strong enough to change the paradigms of host countries having substantial socio-cultural effects on various elements of relationships such as geopolitical diplomatic relations in the region. South Korea has confidently hosted three Asian Games in the last two decades, the 1986 Seoul, 2002 Busan and 2014 Incheon Games. In this study, an investigation of the socio-cultural impacts of the Asian Games held in South Korea in the last two decades is carried out. The focuses of the study are the aspects of globalization, regionalism and reconciliation featured through the three Games. The outcomes of the study may contribute to the understanding of the role of mega sports events in promoting globalization of society and in intertwining with regional states. The Asian Games, as witnessed, which are held while maintaining the motto of the Olympics within Asia, will not only promote the globalization of host countries and cities in the future, but also it will contribute to improving diplomatic relations with neighbouring countries. These games are also predicted to help relieve political tension in the Asia-Pacific region, including the Korean Peninsula. However, as the effects of hosting mega sports events are largely concentrated on the development of their host countries and cities, these events also have the potential to become the seeds of regional conflicts or disputes by creating further competition or a sense of alarm. 相似文献

This paper focuses on four fusion algorithms for the estimation of nonlinear cost function (NCF) in a multisensory environment. In multisensory filtering and control problems, NCF represents a nonlinear multivariate functional of state variables, which can indicate useful information of the target systems for automatic control. To estimate the NCF using multisensory information, we propose one centralized and three decentralized estimation fusion algorithms. For multivariate polynomial NCFs, we propose a simple closed-form computation procedure. For general NCFs, the most popular procedure for the evaluation of their estimates is based on the unscented transformation. The effectiveness and estimation accuracy of the proposed fusion algorithms are demonstrated with theoretical and numerical examples. 相似文献
