A Comparison of Caregiver Report and Performance-Based Measures of Functional Ability in Dementia: An Examination of Moderating VariablesSnyder, Christine M. 01 December 2011 (has links)
The functional abilities of 319 elderly individuals with dementia were assessed using an objective, performance-based measure (the Direct Assessment of Functional Abilities) and caregiver’s report (through the Assessment of Daily Activities and Dementia Severity Rating Scale). The association between the objective measure and caregiver report was examined. Logistic regression analyses demonstrated that caregivers’ reports of instrumental activities of daily living and basic activities of daily living were significantly associated with an objective measure of these functional abilities. Additionally, potential moderating variables were examined. None of the caregiver variables of gender, age, education level, caregiver-care recipient relation, prior and current relationship closeness, and frequency of contact were significant moderators of the association between caregiver report and the objective measure. Caregiver depression, anxiety, emotional status, and distress did not moderate this association. Additionally, none of the care recipient variables of cognitive status, depression, psychiatric symptoms, or dementia duration moderated the association between caregivers’ reports and the objective measure; however, the care recipients’ sensory motor impairments (hand, vision, or hearing impairments) significantly moderated the association between the objective measure and caregiver reports on one measure of functional ability. That is, when the caregiver report indicated mild/moderate functional impairment, the care recipient was 6.52 times as likely to be classified in the more severe group on the objective measure when sensory motor impairments were severe (p < 0.02), whereas the caregiver report and the objective measure were not associated for those care recipients whose caregiver report score indicated severe impairment when sensory motor impairments were mild/moderate (p = 0.24). These results provide some support for the use of proxy reports of functional abilities, with caution advised when the care recipient displays sensory motor impairments.

Process modelling success factors and measuresBandara, Wasana January 2007 (has links)
Business process modelling has gained widespread acceptance, particularly in large IT-enabled business projects. It is applied as a process design and management technique across all project lifecycle phases. While there has been much research on process modelling, there has been little attention on 'how to' conduct process modelling effectively, or on the evaluation of process modelling initiatives and outcomes. This study addresses this gap by deriving a process modelling success model that contains both the success factors (independent variables) and success dimensions (dependent variables) of process modelling. The study employs a multi-method approach, blending both qualitative and quantitative research methods. The research design commenced with a comprehensive literature review, which includes the first annotated bibliography in process modelling research. A multiple case study approach was used to build the conceptual process modelling success model which resulted in a model with eleven (11) success factors (namely Modeller Expertise, Team Structure, Project Management, User Competence, User Participation, Management Support, Leadership, Communication, Modelling Tool, Modelling Language and Modelling Methodology), two (2) moderating variables (namely Process Complexity and Project Importance) and five (5) process modelling success dimensions (namely Modeller Satisfaction, Model Quality, User Satisfaction, Model Use and Modelling Impact). This conceptual model was then operationalised and tested across a global sample, with an online survey instrument. 290 valid responses were received. The constructs were analysed seeking a parsimonious, valid and reliable model. The statistical analysis of this phase assisted in deriving the final process modelling success model. The dependent variables of this model consisted of three (3) contextual success factors (namely Top Management Support, Project Management and Resource Availability), two (2) Modelling specific success factors (namely Modelling Aids and Modeller Expertise), and two (2) moderating variables (namely Importance and Process Complexity). The dependent variable; Process Modelling Success (PMS) was derived with three (3) success measurement dimensions (namely Model Quality, Process Impacts and Process Efficiency). All resulting success factors proved to have a significant role in predicting process modelling success. Interaction effects with the moderating variables (Importance and Process Complexity) proved to exist with Top Management Support (TMS) and Resource Availability (RA). A close analysis to their interaction relationship illustrated that Importance (IMP) moderated the relationship between Top Management Support (TMS) and Process Modelling Success (PMS) in a linear manner and that Process Complexity (PC) moderated the relationship between Resource Availability (RA) and Process Modelling Success (PMS), also in a linear manner. This is the first reported study with empirical evidence on process modelling success. The progressive outcomes of this study have been readily accepted by the practitioner and academic community, with 16 published internationalrefereed- conference papers [including best paper award at the Pacific Asian Conference on Information Systems (PACIS 2004)], 2 journal publications, and over 5 major industry presentations made upon invitation.

Relationships among quality of life, self-care, and affiliated individuation in persons on chronic warfarin therapyGoldstein, Leigh Ann 31 October 2013 (has links)
This descriptive, correlational, cross-sectional study explored the relationships among the variables self-care action, self-care knowledge, and affiliated individuation and quality of life for persons on chronic warfarin therapy. This study also explored the moderating effects of self-care knowledge and affiliated individuation on quality of life. This research was guided by a theoretical framework based on modeling and role-modeling theory (Erickson, Tomlin, & Swain, 1983). The sample consisted of 83 adults between the ages of 30 to 91 years. The majority of participants were Caucasian, educated, retired and almost evenly distributed between male and female. Each subject completed the following instruments: the Oral Anticoagulation Knowledge (OAK) test, the Duke Anticoagulation Satisfaction Scale (DASS), the Basic Needs Satisfaction Inventory (BNSI), and the generic quality of life survey (SF36v2). Data was analyzed using correlation and hierarchical multiple regression analysis. Results indicated significant correlations among most of the study variables. Self-care action significantly explained variances in all but two quality of life variables. Self-care knowledge and affiliated individuation had statistically significant moderating effects on the DASS negative impact and hassles/burdens subscales. Self-care knowledge also demonstrated a significant moderating effect on the SF36v2 physical function subscale. These findings support the concepts proposed by the study's theoretical framework. This research serves as validation of Acton's (1997) study findings for the concept of affiliated individuation and its value as a self-care resource in a specific clinical population. / text

A study of factors moderating Malaysian hospitality students selection of tertiary education institutions, programme and subsequent career intentionsMohd Zahari, M. S. January 2004 (has links)
This study explores the moderating variables that influence a student's decisions to enter into a hospitality management programme and subsequently pursue a career in the hospitality industry. It also examines how these factors are implicated in or modify a student's career commitment over time. The sample includes students enrolling in various three year (6 semester) diploma and undergraduate programme offered by Malaysian hospitality institutions of higher learning over the academic years of 2002- 2003. This includes four public or government funded institutions with several branch campuses, and six private institutions. Predominantly the data for this study based are on self completion questionnaires with some additional insight particularly about respondents' direction of industry employment provided by means of qualitative responses. The initial comparisons are made between students in the public and private institutions and these are followed by an extensive series of analyses examining the differences and similarities of respondents' rating in the two rounds of data collection with reference to a range of independent variables. Also reported are how these ratings change over time. Significant differences were found in terms of parental socio-economic background between students who enrolled in the private and those in the public hospitality institutions. Nevertheless, for the key issues as to whether parental backgrounds lead to differences in respondents' attitudes and values about a career in hospitality this was not seen as an influencing determinant for both institutions. Further, the independent variables of gender, ethnicity, religion and geographical upbringing, secondary school background and prior experience do not clearly show causation of how students reports their views about the dimensions investigated in this study. In fact, students' levels of intention and commitment towards career are apparently not directly related to these independent variables. However, despite no clear pre-tertiary education indicators of likely disaffection being identified, a very clear picture emerged in this study that there is a declining sentiment among Malaysian hospitality students towards employment in the hospitality industry and reduced intention to pursue such a career. These weakened employment intentions are formed during the educational programme and are probably at least partially a result of the maturation process with varying consequences and implications for the students, hospitality institutions, industry and the government.

Acceptans och användning av wearables : En surveyundersökning om hur användningen av wearables i träning kan förklaras med Unified theory of acceptance and use of technology (UTAUT)Visnapuu, Kaspar, Hasselqvist Haglund, Jakob January 2021 (has links)
Wearables som teknologi inom träning är ett etablerat koncept och många använder sig av dessa bärbara enheter. Statistik från Världshälsoorganisationen (WHO) visar att 23% av alla vuxna inte är tillräckligt fysiskt aktiva och forskning visar även på att många slutar använda sina wearables. Samtidigt har det gjorts få studier som undersöker dem faktorer som får användarna att acceptera teknologin. Denna studie kommer med utgångspunkt i UTAUT-modellens konstrukt och demografiska variabler, studera svenskatalande användares acceptans av deras wearable i träning. Den data som studien bygger på samlades in genom en surveyundersökning och analyserades med statistiska metoder. Resultatet av den kvantitativa studien påvisade att intentionen till att använda en wearable i träning har störst påverkan på den faktiska användningen. Intentionen påverkas främst av förväntad prestanda. / Wearable fitness technology is a well known concept, with plenty of users. Statististics from the WorldHealthOrganization show that 23% of all adults do not exercise enough. Other studies have shown that many users stop using their wearable devices, as well as the fact that earlier studies have not focused on explaining acceptance and intention to use wearables in fitness. Following study is based on the constructs and moderating variables of the UTAUT-model and implies to investigate wearables acceptance in fitness of swedish speaking people. The data was gathered by a survey and was analysed using statistical methods. We found that Behavioral intention explained Use behaviour, and the intention to use wearable in fitness was mostly affected by Performance Expectancy.
