A framework for Adaptive Capability Profiling

Bell, Matthew J. January 2015 (has links)
This thesis documents research providing improvements in the field of accessibility modelling, which will be of particular interest as computing becomes increasingly ubiquitous. It is argued that a new approach is required that takes into account the dynamic relationship between users, their technology (both hardware and software) and any additional Assistive Technologies (ATs) that may be required. In addition, the approach must find a balance between fidelity and transportability. A theoretical framework has been developed that is able to represent both users and technology in symmetrical (hierarchical) recursive profiles, using a vocabulary that moves from device-specific to device-agnostic capabilities. The research has resulted in the development of a single unified solution that is able to functionally assess the accessibility of interactions through the use of pattern matching between graph-based profiles. A self-efficacy study was also conducted, which identified the inability of older people to provide the data necessary to drive a system based on the framework. Subsequently, the ethical considerations surrounding the use of automated data collection agents were discussed and a mechanism for representing contextual information was also included. Finally, real user data was collected and processed using a practically implemented prototype to provide an evaluation of the approach. The thesis represents a contribution through its ability to both: (1) accommodate the collection of data from a wide variety of sources, and (2) support accessibility assessments at varying levels of abstraction in order to identify if/where assistance may be necessary. The resulting approach has contributed to a work-package of the Sus-IT project, under the New Dynamics of Ageing (NDA) programme of research in the UK. It has also been presented to a W3C Research and Development Working Group symposium on User Modelling for Accessibility (UM4A). Finally, dissemination has been taken forward through its inclusion as an invited paper presented during a subsequent parallel session within the 8th International Conference on Universal Access in Human-Computer Interaction.

Development of accurate computational methods for simulations of adsorption and diffusion in zeolites

Awati, Rohan Vivek 27 May 2016 (has links)
The overall objective of this thesis has been to develop accurate computational methods for the diffusion and adsorption of small gases in zeolites. Firstly, the effect of the zeolite framework flexiblity on the single component and binary diffusion of various gases were discussed. Results indicate that for tight fitting molecules the rigid framework approximation can produce order(s) of magnitude difference in diffusivities as compared to the simulations performed with a fully flexible framework. We proposed two simple methods in which the flexible structure of a zeolite is approximated as a set of discrete rigid snapshots. Both methods are orders of magnitude more efficient than the simulations with the fully flexible structure. Secondly, we use a combined classical and quantum chemistry based approach to systematically develop the force fields based on DFT calculations for interactions of simple molecules like CH4, N2, linear alkanes, and linear alkenes in zeolites. We used a higher level of theory known as the DFT/CC method to correct DFT energies that were used in the periodic DFT calculations to develop force fields. Our results show that DFT-derived force fields give good predictions of macroscopic properties like adsorption isotherms in zeolites. The force fields are transferrable across zeolites and hence can be further used to screen materials for different storage and separation applications.

A Research Framework for Evaluation of RSV Vaccination Use and RSV Outcomes Among Premature Infants Under One Year of Age

Gibson, Phylliscia 13 May 2016 (has links)
Respiratory Syncytial Virus (RSV) infects the lower respiratory tract in children under the age of two years and is spread through droplet and contact with infected persons. An estimated 200,000 children suffer from complications of RSV annually worldwide. Palivizumab is a monoclonal antibody used to immunize children from RSV and has been on the market since 1988. In 2014, the American Academy of Pediatrics (AAP) updated its policy for recommendation of RSV in premature infants. The objective of this capstone is to propose an evaluation framework with an example of how it could have been applied to assess the impact of the AAP policy change on RSV vaccination use and RSV outcomes among premature infants. The proposed evaluation framework would be a unique link between birth certificate records and surveys of parents/guardians of 32 week gestation premature infants or less in the metropolitan Atlanta area. The birth certificate data would identify “at risk” infants and would allow for selection of a sample of parents/guardians, both pre-policy change (August 1, 2013 to July 30, 2014) and post-policy change (August 1, 2014 to July 30, 2015). The primary endpoints would be: initiation and completion of the RSV vaccine series and RSV infection rates. Moderating variables would be obtained from birth certificate data (e.g. mother’s education and race) and survey data (e.g. attitudes toward vaccine acceptance). The evaluation framework proposed in this Capstone can be used in future analyses of RSV vaccination policy changes. It can also be generalized to other geographic areas in the US and used for routine surveillance of RSV vaccination use and RSV outcomes.

A mentor program analysis

Allen, Michael Scott 17 September 2010 (has links)
Mentor/protégé programs are popular corporate tools, often used to identify and nurture emerging leaders internally, as part of senior management succession planning. This paper provides an analysis of the 2008 Mentor/Protégé program at Analog Devices, Inc from the Human Capital Framework (HCF) perspective. The HCF analysis specifically focuses on identifying implementation “levers” (e.g., human capital) which create or increase capabilities of the organization, to realize strategic goals. This analysis identifies implementation levers from the Mentor/Protégé training program which create new capabilities in the organization, with focus on a Protégé team initiative which developed a new lever to communicate corporate strategy to the organization. / text

Predicting the Use of Aggressive Behaviour among Canadian Amateur Hockey Players: A Psychosocial Examination

Gee, Chris 15 February 2011 (has links)
In the wake of 21 year old Don Sanderson’s death (January 1st, 2009), the direct result of head injuries sustained during an on-ice hockey fight, the social and political appetite for eliminating violence in amateur hockey appears to be at an all time high. Unfortunately, due to a variety of methodological and conceptual limitations previous research is currently unable to provide a unified and valid explanation for sport-specific aggression (Kirker, Tenenbaum, & Mattson, 2000). One of the primary impediments facing our understanding of sport-specific aggression is the descriptive and fragmented nature of the current body of literature. Over the years a number of independent lines of research have been undertaken, through which several psychological and social factors have been identified as potential determinants. However, in many cases these constructs have yet to be tested against athletes’ actual aggressive behaviour in sport and thus their predictive contribution to our understanding is still unknown. Consequently, the purpose of the current investigation was to assess the predictive influence of several commonly cited psychosocial constructs on amateur hockey players actual within-competition use of aggressive behaviour over a competitive season. A trait aggressive personality disposition emerged as the strongest and most stable predictor of athletes’ aggressive behaviour, accounting for 10 – 40% of the statistical variance depending upon the age and competitive level of the athletes under investigation. Differences in the overt expression of the this trait aggressive disposition between age cohorts (bantam / midget) and competitive levels (house league / rep) suggests that environmental and contextual factors also play a significant role in facilitating or repressing athletes’ aggressive behaviour. As such, the results of the current study support an interactive explanation for hockey-related aggression, whereby situational (e.g., team norms, perceived reinforcement) and personal factors (e.g., trait aggressive disposition, ego orientation) interact to either increase or decrease an athlete’s likelihood for committing aggressive penalty infractions over a competitive season. The current results are plotted and discussed within the parameters of Anderson and Bushman’s (2002) General Aggression Model (GAM), which is a frequently cited interactionist framework used in the broader study of human aggression.

Exploring Learning Experiences and Outcomes among Cardiologists Participating in a Web Conference Workshop Series

Pullen, Carolyn 06 November 2012 (has links)
Opportunities for supporting physician continuing professional development (CPD) may exist through careful instructional design and creative use of information and communication technology. The overarching goal of this study was to explore the learning experiences and outcomes of cardiologists participating in a web conference (“webinar”) series to understand the factors that can support webinars in being an appealing and satisfying CPD medium for these learners. Acknowledging that a pedagogically-based framework for program design is a cornerstone of effective CPD (Hutchinson & Estabrooks, 2009; Inan & Lowther, 2007; Casimiro, MacDonald, Thompson, & Stodel, 2009), this study used the W(e)Learn Framework (MacDonald, Stodel, Thompson, & Casimiro, 2009) as a process guide and quality standard for program design, development and delivery. Cardiologists voluntarily participated in an educational webinar series in which they shared their observations and experiences. Informed by the results of a systematic review of physician eLearning design preferences, this dissertation serves as a mechanism to learn about how webinars can be implemented to support learning and practice change within a population of highly specialized physician learners. Methodological approaches included a systematic review of literature examining physician preferences for eLearning design, a case study of webinar implementation, and interviews with cardiologists who participated in the webinars. The findings of the systematic review, the case study and the interviews aligned to characterize key considerations in webinar implementation. Webinar designers must carefully determine program structures, content, and media to create a satisfying learning experience. Cardiologists seek a webinar experience that responds to their professional reality of competing priorities, complex patients, and ambiguous clinical questions. They seek a mix of evidence-based, authentic and challenging content, delivered by credible content experts. The study found that purposefully designed webinars can be a satisfying learning experience for cardiologists with the potential to influence changes in knowledge and practice. The use of an instructional design framework may structure and enrich webinar implementation; this dissertation encourages their use.

A Framework for Software Component Interface Specification and Analysis

Hoyt, Matthew January 2001 (has links)
Although markets are emerging for commercial off-the-shelf components (such as Sun JavaBeans), there are many barriers to widespread component adoption. This is due to the inherent `black-box' nature of software components: developers have no knowledge or control of the component's internal characteristics. Without source or design details, developers only have the component's interface, documentation and test results to answer important questions about reliability, proper use, behavior andperformance. The current best practice of specifying a component's capabilities by providing only the syntax and informal documentation is insufficient to assemble mission or safety-critical systems successfully. To address these problems we have developed a framework forcreating and analyzing the concise specifications of components and their related interfaces. The framework extends a formal model for software architecture descriptions to support the specification of a range of terms. With formal component specifications developers can use the framework to analyze the properties of individual components or of entire systems. Unlike other approaches, the formal basis and implementation of our framework enhance understanding and automates much of thecomponent analysis process.

Beauty and the beast : clients' experience of counselling within a narrative framework, considering concepts of containment and freedom

Bracegirdle, Christina January 2008 (has links)
The experience of opposition between what could be contained in my internal world, and what I wanted freedom from containing while a client in counselling led to the conception of this research. Containment and freedom seemed to form a polarity (Jung 1961; 1969) in that each notion became as necessary as the other. Clients who became participants were in counselling with other counsellors and were asked to keep journals on their thoughts and feelings after counselling sessions and these formed the data for the study. My interest in poetry guided this process as the journals were created by short phrases forming each line and this seemed to influence the writing and analytic process. The journals produced by the participants encouraged the original heuristic (Moustakas 1990) design to surrender the richness that was hidden within it as it became a narrative inquiry. Containment, freedom and the possible polarity between them are investigated as constructs of emotional opposition experienced by the client. The construct and categories which emerge from the data suggest aspects of containment and freedom that demonstrate how emotional movement may occur within the participants through the opposition between containment and freedom. The data also seems to image established theory within the journal stories. A relationship between poetry and the counselling experience is drawn together within the research process as the unconscious and the use of metaphor seem to elicit the discovery of the self. My experiences of personal life events that impact upon the study are held alongside the project as such experiences and the research develop my voice which is relevant to the process and outcome of the work.
