measuring residents attitude toward sustainable tourism development of sustainable tourism attitude scale
Journal of Travel Research, 2005Co-Authors: Hwansuk Chris Choi, Ercan SirakayaAbstract:The purpose of this study is to develop and validate a scale assessing residents’ attitudes toward sustainable tourism (SUS-TAS). Following the pretesting phase, a 51-item scale of resident attitudes toward sustainable community tourism was administered to 800 households in a small tourism community in Texas. Psychometric properties of SUSTAS along with its practical and theoretical implications are discussed within the framework of sustainable tourism development.

typology and dimensionality of litigation public relations strategies the hewlett packard board Pretexting scandal case
Public Relations Review, 2008Co-Authors: Christophe J KelsayAbstract:Abstract This study examined the content of litigation public relations (LPR) strategies Hewlett-Packard used in its recent board Pretexting scandal by analyzing the press releases and newspaper coverage. Seven types of LPR strategies were identified and mapped using multidimensional scaling (MDS) along two continuums representing Defense–Accommodation and Ambiguity–Specification message attributes. Threat type was found to influence the choice of LPR strategies, which in return, impacted on how the publics attributed the organizational responsibility in the crisis. The use of emotional message played an important role in the two new LPR strategies, Information Supply and Strategic Avoidance.

the development and evaluation of a disease specific quality of life measurement tool for shoulder instability the western ontario shoulder instability index wosi
American Journal of Sports Medicine, 1998Co-Authors: Alexandra Kirkley, Sharon Griffin, Heidi Mclintock, Linda NgAbstract:The purpose of this study was to develop a valid, reliable, and responsive disease-specific quality of life measurement tool for patients with shoulder instability. Development included 1) identification of a specific patient population; 2) generation of issues specific to the “disease” (“items”) from reviewing the literature, interviewing health caregivers, and interviewing patients representing all demographics, disease type and severity, and treatments; 3) item reduction using patient-generated frequency-importance products and correlation matrices; and 4) pretesting the prototype instrument on 2 groups of 10 patients. The final instrument, the Western Ontario Shoulder Instability Index, has 21 items representing 4 domains. The instrument attributes (validity, reliability, and responsiveness) were evaluated. Construct validation demonstrated that this index correlated predictably with other measures. Reliability was very high at 2 weeks and 3 months, and the index was more responsive (sensitive to chan...

cognitive interviewing methods for questionnaire pre testing in homeless persons with mental disorders
Journal of Urban Health-bulletin of The New York Academy of Medicine, 2012Co-Authors: Carol E Adair, Anna C Holland, Michelle Patterson, Kate Mason, Paula Goering, Stephen W Hwang, At HomeAbstract:In this study, cognitive interviewing methods were used to test targeted questionnaire items from a battery of quantitative instruments selected for a large multisite trial of supported housing interventions for homeless individuals with mental disorders. Most of the instruments had no published psychometrics in this population. Participants were 30 homeless adults with mental disorders (including substance use disorders) recruited from service agencies in Vancouver, Winnipeg, and Toronto, Canada. Six interviewers, trained in cognitive interviewing methods and using standard interview schedules, conducted the interviews. Questions and, in some cases, instructions, for testing were selected from existing instruments according to a priori criteria. Items on physical and mental health status, housing quality and living situation, substance use, health and justice system service use, and community integration were tested. The focus of testing was on relevance, comprehension, and recall, and on sensitivity/acceptability for this population. Findings were collated across items by site and conclusions validated by interviewers. There was both variation and similarity of responses for identified topics of interest. With respect to relevance, many items on the questionnaires were not applicable to homeless people. Comprehension varied considerably; thus, both checks on understanding and methods to assist comprehension and recall are recommended, particularly for participants with acute symptoms of mental illness and those with cognitive impairment. The acceptability of items ranged widely across the sample, but findings were consistent with previous literature, which indicates that “how you ask” is as important as “what you ask.” Cognitive interviewing methods worked well and elicited information crucial to effective measurement in this unique population. Pretesting study instruments, including standard instruments, for use in special populations such as homeless individuals with mental disorders is important for training interviewers and improving measurement, as well as interpreting findings.

Empirical analysis of weapons of influence, life domains, and demographic-targeting in modern spam: an age-comparative perspective
Crime Science, 2019Co-Authors: Daniela Seabra Oliveira, Tian Lin, Harold Rocha, Sebastian Marin, Huizi Yang, Donovan Ellis, Sandeep Dommaraju, Devon Weir, Natalie C. EbnerAbstract:Spam has been increasingly used for malware distribution. This paper analyzed modern spam from an age-comparative perspective to (i) discover the extent to which psychological weapons of influence and life domains were represented in today’s spam emails and (ii) clarify variations in the use of these weapons and life domains by user demographics. Thirty five young and 32 older participants forwarded 18,605 emails from their spam folder to our study email account. A random set of 961 emails were submitted to qualitative content coding and quantitative statistical analysis. Reciprocation was the most prevalent weapon; financial, leisure, and independence the most prevalent life domains. Older adults received health and independence-related spam emails more frequently, while young adults received leisure and occupation-related spam emails more often. These age differences show a level of targeting by user demographics in current spam campaigns. This targeting shows the need for age-tailored demographic warnings highlighting the presence of influence and Pretexting (life domains) for suspicious emails for improved response to cyber-attacks that could result from spam distribution. The insights from this study and the produced labeled dataset of spam messages can inform the development of the next generation of such solutions, especially those based on machine learning.
