Hierarchical Models for the Analysis of Likert Scales in Regression and Item Response Analysis

Appropriate modelling of Likert-type items should account for the scale level and the specific role of the neutral middle category, which is present in most Likert-type items that are in common use. Powerful hierarchical models that account for both aspects are proposed. To avoid biased estimates, the models separate the neutral category when modelling the effects of explanatory variables on the outcome. The main model that is propagated uses binary response models as building blocks in a hierarchical way. It has the advantage that it can be easily extended to include response style effects and non-linear smooth effects of explanatory variables. By simple transformation of the data, available software for binary response variables can be used to fit the model. The proposed hierarchical model can be used to investigate the effects of covariates on single Likert-type items and also for the analysis of a combination of items. For both cases, estimation tools are provided. The usefulness of the approach is illustrated by applying the methodology to a large data set

Influences of the input factors towards the success of an information system project

This study tried out three input factors which theoretically affect the success of information system (IS) project. These factors were adopted from the McLeod and MacDonell’s (M&M’s) project framework and then examined using survey toward the internal project stakeholder in a sampled institution. A stratified sampling was carried out based on the project experience ownership and then sent both online and paper-based questionnaires to 130 selected respondents. A number of 62 (48%) valid responses were analysed using a partial least squares-structural equation modelling (PLS-SEM) software. The significances of path coefficients, the acceptances of hypotheses, the predictors relevances, and the moderate coefficient determination of the IS project’s success variable present the proposed model approval for the subsequent studies

Influences of the Input Factors towards Success of An Information System Project

This study examines the input factors that were reputed theoretically affecting the information system (IS) project success in term of the processional and causal perspectives. Adopting three of the four dimensions from the McLeod and MacDonell’s (M&M’s) classification project framework dimensions, the study is initiated by inviting the internal project stakeholders in a sampled institution. A stratified sampling then identified 130 people who experienced in the projects as the sample, contacted 90 of the samples via e-mail and  distributed the paper-based questionnaire into 40 certain people especially who are on the managerial level. A number of 62 (48%) valid responses, then were analyzed using the partial least squares-structural equation modeling  (PLS-SEM) software, i.e. SmartPLS. The significances of the whole path coefficients, the acceptances of the overall hypotheses, the relevances of the three predictors relevances, and the moderate coefficient determination of the IS project success variable may present acceptability of the proposed model for the subsequent studies

A Coherent Framework for Understanding the Success of an Information System Project

This paper elucidates the sequential revisions of an information system (IS) project framework across the research model development and its examinations. The authors adopted, adapted, and combined five concepts of the project management discipline and the information processing theory to revise the framework. Besides the use of this multi-dimensional perspective, the authors were also succeeded to present an interrelation between the framework and the examined model within a coherent representation. It was one of the essential points of this model development study, in particular for presenting the research focus. It may be trivial issue for the experts in the research fields, but the coherent illustration is one of the critical issues in the validity measurement of a model, whereas the inexpert ones may need a guideline to represent the interrelationship. Such points became the main contribution of this study to fill the gap in the literatures, particularly in the lack of comprehensive detail of a research model development

Measurement of Information System Project Success Based on Perceptions of the Internal Stakeholders

In this research, adoption of the DeLone and McLean (D&M) information system (IS) success model and its adaptation with the project success theories were used to explore state of IS project success and to examine factors which affect its success. A survey towards the internal project stakeholder in an univerity with response rate 48% was carried out to collect the raw data for Partial Least Squares Structural Equation Modeling (PLS-SEM) analysis. Majority of the participants (80.7%) stated that level of the project success is more than 50% where information quality, system quality, service quality, system use, and user satisfaction substantially explain 64.5% of variance in the success variable. The three quality factors together explain 43.2% of the variance of system use and 70.4% of the variance of user satisfaction. Although, a number of the findings were consistent with the prior studies, these findings also presented inconsistencies especially related to aspects of information quality and system use. Accordingly, researchers and practitioners will be stand to benefit from the information provided in this study and it is hoped that future research will build upon the findings reported herein as efforts are made to attain the IS project success especially in the sampled institution

Disgust as embodied moral judgment.

How, and for whom, does disgust influence moral judgment? In four experiments participants made moral judgments while experiencing extraneous feelings of disgust. Disgust was induced in Experiment 1 by exposure to a bad smell, in Experiment 2 by working in a disgusting room, in Experiment 3 by recalling a physically disgusting experience, and in Experiment 4 through a video induction. In each case, the results showed that disgust can increase the severity of moral judgments relative to controls. Experiment 4 found that disgust had a different effect on moral judgment than did sadness. In addition, Experiments 2-4 showed that the role of disgust in severity of moral judgments depends on participants' sensitivity to their own bodily sensations. Taken together, these data indicate the importance-and specificity-of gut feelings in moral judgments

Managers Perceptions towards the Success of E-performance Reporting System

Managers are the key informants in the information system (IS) success measurements. In fact, besides the determinant agents are rarely involved in the assessments, most of the measurements are also often performed by the technical stakeholders of the systems. Therefore, the results may questionable. This study was carried to explain the factors that influence the success of an e-performance reporting system in an Indonesian university by involving ± 70% of the managers (n=66) in the sampled institution. The DeLone and McLean model was adopted and adapted here following the suggestions of the previous meta-analysis studies. The collected data was analyzed using the partial least squares-structural equation modelling (PLS-SEM) for examining the four hypotheses. Despite the findings revealed acceptances of the overall hypotheses, the weak explanation of the user satisfaction variable towards the net benefit one had been the highlighted point. Besides the study limitations, the point may also be the practical and theoretical considerations for the next studies, especially for the IS success studies in Indonesi

African-American fathers trust/distrust of child welfare agencies, 1999

The proposed study contributes to the knowledge about African-American fathers and child welfare services. Unchallenged stereotypes about African-American fathers are addressed and their perception of previous unfair treatment by past governmental interventions is examined. The impact of psycho-social growth, racial discrimination and risk of harm on African-American families are reviewed via the research review. The research problem examines the relationship between African-American fathers' trust/distrust of governmental agencies and the fathers involvement with a child welfare agency (CWA). The design of the research includes a questionnaire that was designed to collect data from a sample of 50 African-American fathers that have children in foster homes of CWAs in the Atlanta area. The instrument of measurement was designed to allow for an analysis that compares the variables and reports significant relationships. A five point Likert Scale was used to operationalize several types of potential risk of harm that could be associated with involvement with CWAs. A questionnaire was also created to measure caseworkers perception of involvement. The findings from an eventual sample of 20 appear to clearly indicate that those fathers that trust the child welfare agency have higher involvement in recommended services than those fathers that 1 do not trust the agency. The study also appears to validate the theory that those fathers with highest distrust perceive involvement with CWAs inherent with risk of financial loss. The findings have practice and policy implications for child welfare professionals who are increasingly being held more accountable to service and utilize the resources of African-American fathers. This study demonstrates the need for additional study that addresses the questions posed from the perspective of the African-American father and specific ways to engage them
