We propose a method to investigate measurement invariance in the multigroup exploratory factor model, subject to target rotation. We consider both oblique and orthogonal target rotation. This method has clear advantages over other approaches, such as the use of congruence measures. We demonstrate that the model can be implemented readily in the freely available Mx program. We present the results of 2 illustrative analyses, one based on artificial data, and the other on real data relating to personality in male and female psychology students. 相似文献

This paper presents a curriculum design approach for a Masters Programme in Telecommunications Management based on demand data obtained from surveying the needs of potential students of the proposed programme. Through online surveys disseminated at telecom companies in Jordan, it was possible to measure the demand for such a programme and to determine the required programme contents and specifications. The curriculum design is based on definition of programme outcomes and on using a house of quality approach (HOQ) to determine the list of courses required in the programme. Surveyed competencies are mapped to a long list of proposed courses in a HOQ in order to determine the importance of each of these courses. A final list of core and elective courses is then developed considering the contribution to programme outcomes and the academic standards. 相似文献

The needs assessment process, as a tool for decision making, continues to enjoy high visibility in the professional literature, especially in the area of training and human resource development. This literature review explores needs assessment in selected disciplines and provides generalizations about its application. Five needs assessment variables guided our survey of the purposes and methods of the needs assessments described in 106 articles in five general areas (applied sciences, education/technology, medicine/allied health, business/information sciences, and human/public services). 相似文献

The object of this article is to demonstrate that the widely disseminated program LISREL 8 can be used to carry out principal component analyses. LISREL 8 offers a number of useful possibilities including multigroup principal component analysis and principal component regression. Several illustrative analyses are reported. 相似文献

Measurement bias can be detected using structural equation modeling (SEM), by testing measurement invariance with multigroup factor analysis (Jöreskog, 1971;Meredith, 1993;Sörbom, 1974) MIMIC modeling (Muthén, 1989) or restricted factor analysis (Oort, 1992,1998). In educational research, data often have a nested, multilevel structure, for example when data are collected from children in classrooms. Multilevel structures might complicate measurement bias research. In 2-level data, the potentially “biasing trait” or “violator” can be a Level 1 variable (e.g., pupil sex), or a Level 2 variable (e.g., teacher sex). One can also test measurement invariance with respect to the clustering variable (e.g., classroom). This article provides a stepwise approach for the detection of measurement bias with respect to these 3 types of violators. This approach works from Level 1 upward, so the final model accounts for all bias and substantive findings at both levels. The 5 proposed steps are illustrated with data of teacher–child relationships. 相似文献

We present a test for cluster bias, which can be used to detect violations of measurement invariance across clusters in 2-level data. We show how measurement invariance assumptions across clusters imply measurement invariance across levels in a 2-level factor model. Cluster bias is investigated by testing whether the within-level factor loadings are equal to the between-level factor loadings, and whether the between-level residual variances are zero. The test is illustrated with an example from school research. In a simulation study, we show that the cluster bias test has sufficient power, and the proportions of false positives are close to the chosen levels of significance. 相似文献

Background:?Unlike the rest of the UK, Northern Ireland has only recently (2003) implemented legislation regarding the requirement for anti-bullying policies in the province's school system. Purpose:?The purpose of the study was to ascertain the nature of the management of bully/victim problems across Northern Ireland schools prior to the enactment of legislation. Sample:?From an exhaustive sampling frame of all 1329 schools in Northern Ireland (96 nursery, 910 primary, 167 secondary, 73 grammar, 54 special, 29 further education), a total of 285 schools replied to a questionnaire (20 nursery, 181 primary, 41 secondary, 26 grammar, 13 special, 3 further education, 1 non-specified), a return rate of 23.11%. Design and methods:?A review of the literature and consultation with educational experts in Northern Ireland resulted in the development of an ‘Audit’ questionnaire designed to examine dissemination and implementation (or not) of Department of Education, or bespoke, discipline and anti-bullying policies; components of anti-bullying programmes; the communication of anti-bullying policies to the school community; staff training; reporting and management of claims of staff victimisation; sanctions against bullies; and homophobic bullying. Results:?It was found that, in a legislative vacuum, the schools in Northern Ireland had been acting in a proactive manner regarding the management of such bully/victim problems (e.g., development and implementation of policies, effective communication strategies). Conclusions:?These results provide a baseline from which the efficacy of subsequent legislation in Northern Ireland can be evaluated. Utilisation of the methodology adopted in this study would be beneficial in other jurisdictions in evaluations of knowledge, attitudes and management of bully/victim problems, either pre- or post-implementation of legislation. 相似文献

Abstract Lumbar spine injury is common in rowers and examination of spinal kinematics may improve the understanding of this injury's prevalence. This study aimed to examine the range of frontal plane angular displacement (AD) in the lumbar spine at L3 during ergometer rowing and to investigate the effect of exhaustion on lumbar kinematics. Twelve elite male rowers completed an incremental test on a Concept 2 ergometer. Lumbar AD at L3 was measured continually throughout the rowing trial using a Spectrotilt Inclinometer and blood lactate was sampled at 3-minute intervals. AD of between 4.7° and 8.8° was recorded at L3. There was a significant increase in AD between the first and last stage of the test (mean increase = 4.1 ± 1.94°, 95% Confidence Interval [CI], 2.9 to 5.3°, t = 7.36, P = 0.000014). Incremental rise in AD was associated with an incremental rise in blood lactate but regression confirmed that only stroke rate was a significant predictor for increasing angle. Thus there is a statistically significant increase in frontal plane AD at L3 over the course of an incremental exercise test although it cannot be confirmed if this is as a result of exhaustion. The values of AD confirm that there is motion in the frontal plane in ergometer rowing. 相似文献
