A virtual psychiatric ward for orientating patients admitted for the first time

Misconceptions about psychiatric wards frequently cause newly admitted mental patients to stay away from these wards despite their need for treatment. Although ward orientation is typically conducted by nurses in an attempt to help patients to adapt to the new environment, it is considered time-consuming, and the method of orientation and the explanations given may vary among different nurses. This situation calls for a more effective and standardized approach to orientating mental patients on their first admission. To this end, a computer-based interactive virtual environment was developed based on a real psychiatric ward by using virtual reality (VR) technologies. It enables the patient to navigate around to gain understanding about the ward through a virtual guided tour. The effectiveness of this VR orientation approach was investigated by a randomized controlled trial with consecutive sampling. Fifty-four Chinese participants were randomly assigned to undergo ward orientation by either using the VR-based approach or reading text-based electronic information sheets about the ward with a computer. Subjective and objective measures were obtained respectively using the Chinese version of the State-Trait Anxiety Inventory questionnaire and the heart-rate variability measurement before and after the intervention. In addition, a test on the level of understanding about the ward was administered at the end of the session. The results showed that the VR orientation approach is helpful in reducing patients' anxiety while also improving their level of understanding about the ward.     

What makes a group of good citizens? The role of perceived group‐level fit and critical psychological states in organizational teams

Recent studies have expanded the construct of organizational citizenship behaviour (OCB) to the group level and demonstrated its significance in predicting group performance. In this study, we have further expanded this growing stream of research regarding group‐level OCB (GOCB), by identifying distinct group characteristics that predict GOCB. Specifically, we have isolated perceived group–organization (G–O) fit and group–task (G–T) fit as meaningful antecedents of GOCB. We further propose that the perceived G–O and G–T fit influence GOCB by shaping two intermediate psychological states of group members: cohesion and group efficacy. Our findings, which were based on multi‐source data collected from 43 organizational teams, demonstrated that cohesion completely mediated the effect of perceived G–O fit on GOCB. Group efficacy, however, proved not to be a significant mediator of the relationship between perceived G–T fit and GOCB. Instead, G–T fit had a significant direct effect on GOCB. This study highlights the significance of group‐level conceptualization of group–environment interaction as a potential driver of various group processes and outcomes.

Functional Parallel Factor Analysis for Functions of One- and Two-dimensional Arguments

Parallel factor analysis (PARAFAC) is a useful multivariate method for decomposing three-way data that consist of three different types of entities simultaneously. This method estimates trilinear components, each of which is a low-dimensional representation of a set of entities, often called a mode, to explain the maximum variance of the data. Functional PARAFAC permits the entities in different modes to be smooth functions or curves, varying over a continuum, rather than a collection of unconnected responses. The existing functional PARAFAC methods handle functions of a one-dimensional argument (e.g., time) only. In this paper, we propose a new extension of functional PARAFAC for handling three-way data whose responses are sequenced along both a two-dimensional domain (e.g., a plane with x- and y-axis coordinates) and a one-dimensional argument. Technically, the proposed method combines PARAFAC with basis function expansion approximations, using a set of piecewise quadratic finite element basis functions for estimating two-dimensional smooth functions and a set of one-dimensional basis functions for estimating one-dimensional smooth functions. In a simulation study, the proposed method appeared to outperform the conventional PARAFAC. We apply the method to EEG data to demonstrate its empirical usefulness.     

Competitive factors of electronic dance music festivals with Social Networking Service (SNS) citizenship behaviour of international tourists

This study examined the comparative advantages of prestige service labelling (VIP), online marketing, and image differentiation when applied as marketing strategies to build tourist loyalty as a component of citizenship behaviour. The participants were 220 African tourists attending the World Club Dome Korea 2017 festival event. Following data collection, we conducted a hierarchical regression analysis to determine how VIP, online marketing, and image differentiation influenced tourist social networking service (SNS) citizenship behaviour. The results suggest that VIP and image differentiation to positively predict SNS citizenship behaviour, whereas this was not the case for online marketing. VIP had a higher influence on tourist SNS citizenship behaviour than image differentiation. In summary, strategies to attract tourists with high purchasing power should include prestige service branding with clear image differentiation. This exclusivity could be applied to online ticketing services for their added value to tourism promotion.
