Examining the Impact of Multicollinearity in Discovering Higher-Order Factor Models

Theory-driven structural equation modeling (SEM) is an increasingly popular technique for analyzing quantitative data in Information Systems research. Since 1994, 20% of all papers in top-tier journals use structural equation modeling [Urbach and Ahlemann, 2010]. Higher-order factor structures have been widely discussed from a number of theoretical perspectives [e.g., Bagozzi and Edwards, 1998; Hayduk, Ratner, Johnson and Bottorff, 1995; Law, Wong and Mobley, 1998]. Our intention is not to contradict these theoretical discussions but to postulate that empirical analysis can assist in the discovery of emergent higher-order structures where perhaps not initially proposed. As constructs have become both more numerous and specific, the existence of higher levels of multicollinearity, even when discriminant validity is evident, are becoming problematic for assessing the role of individual constructs. Thus, there becomes a need for a higher-order structure to represent these relationships. In this paper, we present a six-step methodology for researchers who have structural models suffering from multicollinearity, positing that multicollinearity can obscure an underlying higher-order structure. We present findings from an empirical study where multicollinearity had masked the presence of a higher-order structure. We conclude with a proposed methodology for discovering higher-order factor models

ANALYSING THREE BASIC DECISIONS OF TOURISTS: GOING AWAY, GOING ABROAD AND GOING ON TOUR

This study analyses determinant factors in the taking of three basic decisions on the part of holidaymakers: going on holiday, foreign holidays and multi-destination holidays. We propose various research hypotheses relating to the impact on these decisions of various personal characteristics. The methodology used estimates various Binomial Logit models. The empirical application carried out in Spain on a sample of 3,781 individuals allows us to conclude that personal characteristics related to the chosen destination, personal restrictions and socio-demographic and psychographic characteristics are determinants of these decisions.

Factors affecting e-government adoption in the state of Qatar

Electronic government (e-government) initiatives are in their early stages in many developing countries and faced with various issues pertaining to their implementation, adoption and diffusion. Although e-government has increased transparency and improved communication and access to information for citizens, digital diffusion of information is often achieved at high cost to government agencies. Conversely, citizens’ adoption of e-government services has been less than satisfactory in most countries. While studies by researchers continue to outline the most salient adoption constructs, as well as various frameworks and models for understanding adoption, research by independent consultancy/research organisations has produced a host of statistics and league tables of good and bad practices of service delivery. Like many other developing countries, the e-government initiative in the state of Qatar has faced a number of challenges since its inception in 2000. This study utilises the Unified Theory of Acceptance and Use of Technology (UTAUT) to explore the adoption of e-government services in the state of Qatar. 1179 citizens were surveyed to collect primary data. A regression analysis was conducted to examine the influence of the factors adapted from the UTAUT on e-government adoption. Reliability test reported values of the various constructs vary between (0.74) and (0.91). The findings reveal that effort expectancy and social influences determine citizens’ behavioural intention towards e-government. Additionally, facilitating conditions and behavioural intention were found to determine citizens’ use of e-government services in Qatar. Implications for practice and research are discussed

Culture in the design of mHealth UI:An effort to increase acceptance among culturally specific groups

Purpose: Designers of mobile applications have long understood the importance of users’ preferences in making the user experience easier, convenient and therefore valuable. The cultural aspects of groups of users are among the key features of users’ design preferences, because each group’s preferences depend on various features that are culturally compatible. The process of integrating culture into the design of a system has always been an important ingredient for effective and interactive human computer interface. This study aims to investigate the design of a mobile health (mHealth) application user interface (UI) based on Arabic culture. It was argued that integrating certain cultural values of specific groups of users into the design of UI would increase their acceptance of the technology. Design/methodology/approach: A total of 135 users responded to an online survey about their acceptance of a culturally designed mHealth. Findings: The findings showed that culturally based language, colours, layout and images had a significant relationship with users’ behavioural intention to use the culturally based mHealth UI. Research limitations/implications: First, the sample and the data collected of this study were restricted to Arab users and Arab culture; therefore, the results cannot be generalized to other cultures and users. Second, the adapted unified theory of acceptance and use of technology model was used in this study instead of the new version, which may expose new perceptions. Third, the cultural aspects of UI design in this study were limited to the images, colours, language and layout. Practical implications: It encourages UI designers to implement the relevant cultural aspects while developing mobile applications. Originality/value: Embedding Arab cultural aspects in designing UI for mobile applications to satisfy Arab users and enhance their acceptance toward using mobile applications, which will reflect positively on their lives.</p

Could the ease of doing business be considered a predictor of countries' socio-economic wealth? An empirical analysis using pls-sem

The wealth of nations differs significantly due to different factors. One of the reasons identified by previous studies is the level of entrepreneurship promotion by governments. This aspect has scarcely been studied empirically to date. Therefore, this paper sheds some light on this regard through building a construct out of ten Ease of Doing Business Index (EDBI) measures developed by the World Bank and relating it with a construct shaped by two measures of socio-economic wealth (SEW), namely gross domestic product and the Human Development Index. To this end, we conduct a structural equation model analysis using partial least squares (PLS-SEM) method with a 2018 database comprising secondary data from 190 countries. As the main contribution of this study, the results show that good performance in the EDBI ranking predicts good performance in the SEW ranking. Additionally, this study is pioneer in the use of these rankings to build composite constructs (latent variables) and relate them. For these reasons, our findings are useful for both academia and governments responsible for promoting entrepreneurship, as this latter is identified as the key enabler of economic development

The moderating effect of brand orientation on inter-firm market orientation and performance

While prior research has shown that market and brand orientation are key contributors to successful business performance, research to date has not fully explored how inter firm collaboration for these two key orientations can enhance business performance. The purpose of the paper is to investigate the relationship between inter-firm market and performance; to test for the moderating role of brand orientation in that relationship. A total of 169 completed pairs of surveys were collected of small and medium enterprises operating internationally in a variety of industries in Switzerland. The results show that inter-firm market and brand orientation are two antecedents of marketing and financial performance. The impact of inter-firm market on marketing and financial performance is significant when the brand orientation is favorable. This study extends previous research by examining the moderating role of brand orientation on inter firm market orientation, which is important, especially for firms wanting to increase their brand reputation by entering into partnerships with other firms. Further research is indicated, to identify the key moderators of the driving force of inter-firm market in relation to business performance and the reason why maintaining a strong brand presence is important in the international marketplace

Modelling abstention rate using spatial regression

Dissertation presented as the partial requirement for obtaining a Master's degree in Statistics and Information Management, specialization in Information Analysis and ManagementDuring the last few elections that were held in Portugal, there have been very low percentages of voter turnout. This will obviously impact the result of those elections and can maybe be related to the general disenchantment of the population regarding the country’s recent political environment. This study aims to contribute to a better understanding of the patterns in the abstention rate of the last elections in Portugal. Sociological and economic variables such as age, unemployment rate, education level and many others will be used in trying to find out if they influence the abstention rate. It is logical to assume that the abstention rate in a certain municipality will be related to the abstention in neighboring municipalities. Therefore, the study also investigates if there is spatial autocorrelation in the abstention rates. Modeling a phenomenon like this with a simple linear regression model, estimated by Ordinary Least Squares (OLS), will render less efficient and biased results because of the spatial correlation of the observations and possible spatial clustering of values. Spatial regression methods have been proposed to overcome these drawbacks, particularly the Geographically Weighted Regression (GWR). This method will take into account possible local influences, allowing the coefficients of the model to vary depending on the geographic location, possibly obtaining a more appropriate fit. Many different OLS and GWR models were investigated by considering different combinations of explanatory variables and diagnosing their results through statistical tests and goodness-of-fit measures. Results show that indeed the data exhibits a non-random spatial pattern, and that a GWR model is a better approach in modeling abstention rates, when compared to an OLS model. Hence, the percentage of voter turnout in a municipality is likely to be better modelled taking into account its geographic location

El potencial de la teoría cognitiva en la enseñanza de la contabilidad y auditoría

El artículo examina la asimilación de dos conceptos contables complejos: la imagen fiel (TFV) y el valor razonable (FV) en una muestra de estudiantes de Contabilidad Financiera. El objetivo es evaluar la opinión de los estudiantes sobre TFV y FV durante su educación y detectar si las percepciones cambian con su nivel académico y madurez. La metodología utilizada es una encuesta de opinión. Las respuestas obtenidas muestran que los estudiantes consideran que la TFV es un concepto superior a otros principios contables. Además, en el estudio se observa que las respuestas de los estudiantes dependen del nivel académico y la madurez. Por último, se considera que los postulados que establece la teoría cognitiva podrían servir a los instructores en materia de contabilidad y organismos reguladores para mejorar el proceso de aprendizaje así como la calidad de la información financiera.This paper examines the understanding of two complex accounting concepts: true and fair view (TFV) and fair value (FV) by students in Financial Accounting. The correct assimilation of these concepts is assessed as to whether there are differences in concept perception due to academic level and maturity. We use a survey to examine the perception and assimilation of the TFV and FV. The evidence suggests that accounting students consider that TFV is a superior accounting concept over other accounting principles. Additionally, the study identifies a pattern of change depending on the academic level and maturity of the participants. On discovering differences, a proposal is made to use the Cognitive Load Theory (CLT) by standard setters and instructors in accounting and auditing to improve the learning process and the quality of financial information.Ministerio de Innovación y Ciencia DER2009-09539 ECO2010-17463 ECO2010-21627 DER2012-33367 DER2015-67918PConsejería de Educacion y Ciencia Castilla-La Mancha POII10-0134-5011Universidad de Alcalá CCG20014/HUM-03
