This paper proposes an innovative method for factor analyzing data that potentially contains individual response bias. Past methods include the use of “ipsative” data, or, related to that, “ipsatized” data. Unfortunately, factor analysis as the main method used for analyzing the dimensionality of data, cannot be applied to ipsative data. In contrast, normalization of data as an alternative method to filter out response bias, is not hampered by the technical statistical issues inherent to applying multivariate techniques to ipsative data. Using high-quality data from a survey in Nepal that makes use of – among others – the High-Performance Organizations (HPO) framework, this paper shows that the traditional approach of directly applying Confirmatory Factor Analysis (CFA) starting from an existing model or theory, is inferior to our approach. Even applying Exploratory Factor Analysis (EFA) to the raw (non-normalized) data before using CFA, is unable to detect the optimal dimensionality, or structure, in the data. A better structure can be obtained by performing EFA on normalized data that corrects for response bias in the raw data. This paper convincingly shows that the newly identified structure is superior to the original structure suggested by the HPO framework. Applying a CFA using the newly detected structure on the raw data, gives excellent goodness-of-fit statistics, with more items retained, and no need of forced methods to improve the model fit. The findings suggest that existing models and questionnaires based on these models, are not necessarily as valid and reliable as empirical studies that make use of traditional analyses seem to suggest. When adopting existing instruments, researchers are advised to critically check the validity and reliability of these instruments – especially those vulnerable to response bias - and to apply the procedures laid out in this paper, in order to enhance the quality of their research, and to inform future researchers who consider using the same instruments or to warn them about the potential shortcomings of these instruments.

In this critical review article, Isaac and Platenkamp present the case that tourism is not isolated from the world's dramatic situations in which humanity is at stake. Their argument principally centers on the devastating historical and contemporary conflict in Palestine and its relations with tourism. In this article, Isaac and Platenkamp maintain that (in relation to current happenings in Palestine) ethical and moral argumentation would be beside the point, and might even be a "cynical" exercise. They suggest that the conflict there is imbued with many kinds of normative argumentation. It is their view that positions need to be taken with regard to "Palestine," as in all extreme circumstances, where at the same time respect for the other positions becomes crucial. In this critical review article, therefore, Arendt's idea of "agora" will be introduced, in order to create a space where these "respectful positions" can be taken in a public arena and in order to contribute to a possible peaceful development. To Isaac and Platenkamp, tourism could enable this sort of "peaceful development" and could promote or help empower conditions where violence would be excluded, and where different sorts of "argumentation" could be generated and heard about these so-called "controversial spaces." In these respects, they maintain that tourism is a challenging field, because it has (itself) many faces-and they argue that such scenarios for "tourism" indeed could apply/should be applied for many controversial other spaces like Nepal and Burma (for instance) where (as in Palestine) the original population has no say in any economic development, such as that of tourism. But Isaac and Platenkamp recognize that (even in Burma) resistance against injustice can never be destroyed. Their own principal focus remains targeted upon Palestine, though. There, tourism is known to have "an incredibly high potential," despite the fact that (in their view) a strong and powerful "Israeli self" indeed controls the "humiliated Palestinian other." Thus, to our two reviewers in the Netherlands, therefore, tourism seems to be a communicative activity that might enable the implementation of Arendt's idea of and about "the agora." Isaac and Platenkamp suggest that there is no violence in the agora, itself, because only the force of argumentation rules. there.
