This dissertation introduces a new method, Pratt's measure matrix, for interpreting multidimensional oblique factor models in both exploratory and confirmatory contexts. Overall, my thesis, supported by empirical evidence, refutes the currently recommended and practiced methods for understanding an oblique factor model; that is, interpreting the pattern matrix or structure matrix alone or juxtaposing both without integrating the information. Chapter Two reviews the complexities of interpreting a multidimensional factor solution due to factor correlation (i.e., obliquity). Three major complexities highlighted are (1) the inconsistency between the pattern and structure coefficients, (2) the distortion of additive properties, and (3) the inappropriateness of the traditional cut-off rules as being "meaningful". Chapter Three provides the theoretical rationale for adapting Pratt's importance measures from their use in multiple regression to that of factor analysis. The new method is demonstrated and tested with both continuous and categorical data in exploratory factor analysis. The results show that Pratt's measures are applicable to factor analysis and are able to resolve three interpretational complexities arising from factor obliquity. In the context of confirmatory factor analysis, Chapter Four warns researchers that a structure coefficient could be entirely spurious due to factor obliquity as well as zero constraint on its corresponding pattern coefficient. Interpreting such structure coefficients as Graham et al. (2003) suggested can be problematic. The mathematically more justified method is to transform the pattern and structure coefficients into Pratt's measures. The last chapter describes eight novel contributions in this dissertation. The new method is the first attempt ever at ordering the importance of latent variables for multivariate data. It is also the first attempt at demonstrating and explicating the existence, mechanism, and implications of the suppression effect in factor analyses. Specifically, the new method resolves the three interpretational problems due to factor obliquity, assists in identifying a better-fitting exploratory factor model, proves that a structure coefficient in a confirmatory factor analysis with a zero pattern constraint is entirely spurious, avoids the debate over the choice of oblique and orthogonal factor rotation, and last but not least, provides a tool for consolidating the role off actors as the underlying causes.

As a consequence of globalization and liberalization on trade, transnational economic activities have interacted massively and vigorously. Opening of trading market has generally brought greater opportunities to domestic logistics/transportation operation industry, but accompanied with fierce direct competition with international players as well. In recent years, mega overseas air cargo transportation companies provide the consumers with more diverse and integrated services through strategic alliances and acquisition of smaller players. However, it squeezes and threatens the existence of domestic international air cargo transportation companies severely. Thus, ¡§The International Air Cargo Transportation Industry Alliance¡¨ was established by domestic players in Taiwan in an attempt to counter the threat and to impel themselves into a more internationalized player on the stage of air cargo transportation. The main purpose of this research is to discuss the influence factors of the willingness of forming of strategic alliances by Taiwanese air cargo transportation companies and to generalize an objective conclusion. Furthermore, it offers some suggestions on the development of the strategic alliances of the domestic international air cargo transportation industry.
