Mining sequential causal patterns with user-specified skeletons in multi-sequence of event data

The approaches proposed in the past for discovering sequential patterns mainly focused on single sequential data. In the real world, however, some sequential patterns hide their essences among multi-sequential event data. It has been noted that knowledge discovery with either user-specified constraints, or templates, or skeletons is receiving wide attention because it is more efficient and avoids the tedious selection of useful patterns from the mass-produced results. In this paper, a novel pattern in multi-sequential event data that are correlated and its mining approach are presented. We call this pattern sequential causal pattern. A group of skeletons of sequential causal patterns, which may be specified by the user or generated by the program, are verified or mined by embedding them into the mining engine. Experiments show that this method, when applied to discovering the occurring regularities of a crop pest in a region, is successful in mining sequential causal patterns with user-specified skeletons in multi-sequential event data.

Analysis of satisfaction at Gallipoli on ANZAC day, 2007 : results of a survey of event participants

This paper explores the critical success factors of special events, in this case the Anzac Day commemorations at Gallipoli, Turkey. This event has become increasingly popular in recent years with crowd numbers growing to around 20,000 people traveling to attend the 2005 Dawn Service at historic Anzac Cove on Anzac day. The aim of this research is to investigate the success factors associated with Anzac Day commemorations at Gallipoli and to assess how these influence visitor satisfaction. Data was collected from 331 attendees of Anzac Day commemorations at Gallipoli while they were in transit from Gallipoli to Istanbul on 25 April 2007. The analysis of this data was undertaken using exploratory and confirmatory factor analysis as a basis to the development of a model of satisfaction using structural equation modeling. In this case constructs relating to amenities, transport, ceremonies and recommending behavior were found to be significant predictors of event satisfaction. These issues during the event were found to be of equal importance for both genders and all age groups.

Application of extended multivariate modeling for information flow analysis of event related responses

Event related potential (ERP) analysis is one of the most widely used methods in cognitive neuroscience research to study the physiological correlates of sensory, perceptual and cognitive activity associated with processing information. To this end information flow or dynamic effective connectivity analysis is a vital technique to understand the higher cognitive processing under different events. In this paper we present a Granger causality (GC)-based connectivity estimation applied to ERP data analysis. In contrast to the generally used strictly causal multivariate autoregressive model, we use an extended multivariate autoregressive model (eMVAR) which also accounts for any instantaneous interaction among variables under consideration. The experimental data used in the paper is based on a single subject data set for erroneous button press response from a two-back with feedback continuous performance task (CPT). In order to demonstrate the feasibility of application of eMVAR models in source space connectivity studies, we use cortical source time series data estimated using blind source separation or independent component analysis (ICA) for this data set.

The roles of prior experience and the timing of misinformation presentation on young children's event memories

The current study addressed how the timing of interviews affected children's memories of unique and repeated events. Five- to six-year-olds (N= 125) participated in activities 1 or 4 times and were misinformed either 3 or 21 days after the only or last event. Although single-experience children were subsequently less accurate in the 21- versus 3-day condition, the timing of the misinformation session did not affect memories of repeated-experience children regarding invariant details. Children were more suggestible in the 21- versus 3-day condition for variable details when the test occurred soon after misinformation presentation. Thus, timing differentially affected memories of single and repeated events and depended on the combination of event-misinformation and misinformation-test delays rather than the overall retention interval.

Evidence of metacognitive awareness in young children who have experienced a repeated event

Two studies examined children's confidence judgments in the accuracy of their memories after repeated experience of an event. Children aged 5 to 6 years took part in an event once or four times, were provided with misinformation either shortly after (Study 1) or a while after (Study 2), and interviewed with yes/no recognition questions 3 months later. Children in the repeated-experience conditions were highly confident of their accurate responses to questions about items that were identical rather than variable across occurrences, and this discrimination was best at the shorter delay. The results show that children were able to metacognitively monitor the accuracy of their responses to qualitatively different kinds of details, and indicate that age is not the only determinant of metacognitive awareness after being misled. Rather, the nature of event representations must also be considered.

Battlefield tourism in Turkey : an empirical analysis of British ex-colonial event attendance

This paper explores the influence of visitor satisfaction on intention to recommend event attendance. The Anzac Day commemoration at Gallipoli, Turkey, an event that has become increasingly popular in recent years and provides the backdrop for the current study. Some 20,000 people travel to attend this event. Data was collected from 331 attendees while they were in transit from Gallipoli to Istanbul on 25 April 2007. The analysis of this data was undertaken using factor analysis as a basis for identifying model constructs to be tested using structural equation modelling. Findings suggest that the constructs relating to the ceremonies held at Anzac Cove and Lone Pine and the experiential and emotional aspects of the event were significant predictors of event satisfaction and subsequent recommending behaviour. The implications of these findings for events in general and the success of the Anzac Day commemorations at Gallipoli are discussed.

Event valence and unrealistic optimism

The effect of event valence on unrealistic optimism was studied. 94 Deakin University students rated the comparative likelihood that they would experience either a controllable or an uncontrollable health-related event. Valence was manipulated to be positive (outcome was desirable) or negative (outcome was undesirable) by varying the way a given event was framed. Particiapants either were told the conditions which promote the event and rated the comparative likelihood they would experience it or were told the conditions which prevent the event and rated the comparative likelihood they would avoid it. For both the controllable and the uncontrollable events, unrealistic optimism was greater for negative than positive valence. It is suggested that a combination of the 'motivational account' of unrealistic optimism and prospect theory provides a good explanation of the results. 

A model of the affective and congnitive events in expatriate assignments

In this paper, we take a step toward explaining how events occurring within the expatriate assignment are perceived and interpreted. In particular, we consider the conditions under which individuals perceive hassles and uplifts during intercultural interactions as a cognitive or affective event and, how the type of event influences the outcomes associated with a given event. In doing so, we develop a model to propose how characteristics of the perceiver and the event influence whether interactions in the expatriate assignment are perceived as a cognitive or affective event and, how the type of event influences the outcomes associated with a given event.

The effect of events context on children's recall of non-experienced events across mutiple interviews

Purpose: The current study examined whether young children's willingness to assent to, and provide details about, a false (non-experienced) activity differs depending on whether the activity was allegedly embedded within (a) a specific event or (b) a broad (non-specified) time frame.
Method:  Ninety-nine children aged 4--5 years (from both low and high socioeconomic backgrounds) either (a) participated in a staged event that consisted of two activities or (b) did not participate in the staged event. One or two days later, all children were given false suggestions about a non-experienced (false) activity that had either high or low plausibility. Approximately 8, 15, and 22 days after the event, children were asked to recall the activities, and to answer a series of specific cued-recall questions.
Results: There was no effect of event context on assent rates, and the rate at which children reported interviewer suggestions. However, children who participated in the staged event provided fewer details about the false activity. Further, among those children who assented to the false activity, fewer subjects, objects, actions, temporal markers, locations, fantastic/improbable details, and confabulation errors were reported when the activity was embedded within the specific staged event.
Conclusion: The degree of error in children's accounts of a completely false activity is reduced when the activity is suggested to have occurred within a specified event as opposed to a broad (non-specified) time frame.

Session initiation protocol (SIP) based event notification system architecture for telemedicine applications

Mobility service for hospital technicians involved in telemedicine applications is one of the key issues in providing more flexible and efficient in-house or remote health care services. Today, the Internet based communication has widened the opportunity of event monitoring systems in the medical field. The session initiation protocol (SIP) can work on a variety of devices and can be used to create a medical event notification system. Its adoption as the protocol of choice for third generation wireless networks allows for a robust and scalable environment. One of the advantages of SIP is that it supports personal mobility through the separation of user addressing and device addressing. In this paper, the authors propose a possible solution framework for telemedicine alert notification system based SIP-specific event notification.

Unrealistic optimism and event threat

Individuals typically exhibit “unrealistic optimism” (UO), the belief that they are less likely than the average person to experience a negative event. This may be because, fearing the event, they try to reassure themselves by distorting their reasoning to conclude that they are at comparatively little risk. If this is so, the greater the “event threat” (i.e., the more serious the event's consequences and/or the greater the likelihood that those consequences will be experienced), the more reassurance should be required, and the greater the UO that should be observed. This prediction was tested in a study in which students (N = 148) were informed about a type of heart disease that could develop in later life due to inadequate diet when young. The risk attributable to diet was stated to be either slight (low-threat condition) or great (high-threat condition). Participants were asked to rate their own risk and that of the average student of developing the disease; question order was counterbalanced. The effects of event threat and question order were found to interact: event threat affected UO in the predicted way, but only when the question about own risk came first. The results are explained in motivational terms. Implications for health education are discussed.

Examining the relationship between event owners and host destinations

The event sector has often come under the scrutiny of the public. A cursory glance at print and electronic media highlights some of the many negative attitudes social commentators and residents of host destinations have of special events. While there are a number of stakeholders of events, two entities which play a pivotal role in whether, when, and how events are delivered are the event governing bodies (or owners) and the host destinations. This paper examines the relationship between these two stakeholders. Research questions guiding this study are: Do event owners vary in their interactions with event destinations? Should event destinations be more discerning in their selection of the events they host? Can event destinations be more discerning in their selection of the events that they bid for?

While considerable research has focused on the relationship between event owners and host destinations during the event bidding process, this study aimed to explore the relationship more generally to provide greater insights into the event planning process. Thus, the study aimed to address a gap in knowledge about event marketing and management to understand motives for destinations to engage with event owners, and ultimately to enhance the quality of the event experience (for both attendees and non-attendees). A qualitative research approach was employed for this study, with elite interviews being the main data collection method.

The findings indicate that the relationship between event owners and host destinations can be highly problematic. A number of factors were identified as contributing to this situation, including the varying objectives that event owners have for their events; the way in which these objectives are congruent (or not) with host destinations objectives for events in their community; and the way in which a potential match or mis-match of objectives impacts a host destination’s ability to leverage an event. Overall, the researchers concluded that when there is disparity between the culture of the event owners’ organisation, and the social culture of the host destination, this situation is exacerbated. When event owners demonstrated empathy and an understanding of the host destination’s culture, and an understanding of the host destination’s aim for delivering an event, greater levels of perceived success are evident.

In the past, the bid process has been highly competitive. Host destinations have been at the mercy of event owners. However, the authors of this study indicate that as a result of this research, host destinations should be more discerning with regard to which event owners they ‘lie in bed with’ to ensure that the outcomes of the events are beneficial for their myriad stakeholders. It is acknowledged that the event planning and execution process is set within a political market square, as per Larson and Wikstrom’s (2001) suggestion, and that this context provides a fertile ground for research on this topic.

An examination of police officers' notes of interviews with alleged child abuse victims

This study provided a critical examination of handwritten records (notes) of interviews contained in a sample of 89 police case files about alleged child abuse. Some of the notes examined related to initial disclosure (complaint) interviews which were not electronically recorded and were meant to be recorded verbatim. Notes of electronically recorded interviews, which merely constituted a convenient summary of the case details, were also examined. Collectively, the analyses focused on the accessibility, completeness and accuracy of the notes, and the degree to which the interviewers' questions and witnesses' answers were differentiated. In relation to the disclosure interviews, a substantial proportion of these were not accessible. Of those where the notes were obtained, the detail recorded was not a complete record of conversation, and there was often poor delineation of questions and responses. Analysis of the electronically recorded interviews showed that these were not an entirely accurate summary of event details even though the note takers' sole task was to document the interview. The implications of these findings are discussed.

A model of predictors of attendance at major sporting events

Sports events represent a major category of event revenue contributing economic benefits to cities and regions. Attendance at sports events is recognised as an important activity (Shamir and Ruskin 1984), but over the past 20 years sports event attendance expenditure has declined (Ross 2006). Consequently, understanding the factors that influence sports event attendance is crucial to the sustainability of these events. This study identifies the antecedents of sports event attendance among 460 respondents who were surveyed in Melbourne, Australia. Structural Equation Modelling was used to test an empirical model of attendance motivations. The model identifies constructs relating to emotional responses and facilities, as the predictors of event attendance.
