Almost all goodness-of-fit indexes (GFIs) for latent variable structural equation models are global GFIs that simultaneously assess the fits of the measurement and structural portions of the model. In one sense, this is an elegant feature of overall model GFIs, but in another sense, it is unfortunate as the fits of the 2 different portions of the model cannot be assessed independently. We (a) review the developing literature on this issue, (b) propose 6 new GFIs that are designed to evaluate the structural portion of latent variable models independently of the measurement model, (c) that are couched within a general taxonomy of James, Mulaik, and Brett's (1982) Conditions 9 and 10 for causal inference from nonexperimental data, (d) conduct a Monte Carlo simulation of the usefulness of these 6 new GFIs for model selection, and (e) on the basis of simulation results provide recommended criteria for 4 of them. Supplemental analyses also compare 2 of the new GFIs to 2 other structural model selection strategies currently in use. (PsycINFO Database Record

ABSTRACT. The emergence of Internet-based distribution channels has created both opportunities for and challenges to the travel agencies. Based on the customer-value perspective, this study focused on exploring the relative weights of the nine proposed fundamental travel products from an Internet perspective.The study cohort comprised customers who had purchased room products from travel agencies websites, with data collected using a questionnaire survey. Customers were surveyed during a 3-month period at Taipei International Airport. Excluding useless questionnaires resulted in 131 respondents, corresponding to a response rate of 18.71%.We found that privacy, safety, and product quality were the three most important factors influencing customer purchases of room products on the Internet. The results of this study have some implications for travel agencies-companies will need to make a significant investment in website design of safety mechanism, and the greater the effort managers make to alleviate these concerns, the more likely it is that consumers will visit and buy products on their website.

Whereas Lievens and Motowidlo (2016) propose a model of situational judgment test (SJT) performance that removes the "situation" in favor of conceptualizing SJTs as a measure of general domain knowledge, we argue that the expression of general domain knowledge is in fact contingent on situational judgment. As we explain, the evidence cited by Lievens and Motowidlo against a situational component does not inherently exclude the importance of situations from SJTs and does overlook the strong support for a person-situation interaction explanation of behavior. Based on the interactionist literature-in particular, the trait activation theory (TAT) and situational strength literatures-we propose a model that both maintains the key pathways and definitions posited by Lievens and Motowidlo and integrates the situational component of SJTs.Interactionist explanations of work behavior have received increasing attention and support in the employee selection literature and stem from a long history of research on person-situation models of personality (e.g., Mischel, 1968). The ability to evaluate situational demands predicts performance across assessment types, including structured interviews (Melchers, Bösser, Hartstein, & Kleinmann, 2012) and assessment centers (Jansen et al., 2013). Further, the ability to identify criteria for performance evaluation (broadly conceptualized as situational cues) has been posited as a key explanation of the criterion-related validity for selection assessments (Kleinmann et al., 2011). Given the evidence supporting a person-situation interaction account of performance in assessment centers and structured

AbstractPurpose -The purpose of this paper is to investigate the motivations behind people's intentions to continue knowledge sharing (continuance intention) in open professional virtual communities. Design/methodology/approach -Data collected from 270 members of a professional virtual community provides partial support for the proposed model. LISREL 8.5 was used to analyse the measurement and structural models. Findings -The results show that playfulness is critical for the community members' satisfaction and continuance intention. However, only positive self-worth disconfirmation, distributive justice, and interactional justice can influence the satisfaction of the community members.Research limitations/implications -The data were collected from a single open professional community; the generalisation of the model and findings to other virtual communities requires additional research. The findings imply that justice factors appear to be important in leading to higher satisfaction levels. Practical implications -Developers of virtual communities should create a more enjoyable online environment and raise the core knowledge contributors' sense of self-worth. Originality/value -A theoretical model was constructed in which individual motivation factors, social network factors, and justice theory are integrated with expectancy disconfirmation theory to investigate the motivations behind people's continuance intention.
