An examination of attitude toward change as a predictor of policy/program implementation

Policy/program implementation, e.g., the process of fulfilling policy/program directives, is fundamentally tied to change. Implementation studies have examined the process, identifying many critical organizational variables although individuals perform the activities.^ Many of the studies are predicated on the rational, goal oriented model of organizations and examine implementation, presenting only the goal-oriented view. Organizational change and its resistance, however, are not fully explained by the rational model of organizations. There are other schools of thought providing different views of organizations from which explanation may emerge. Bolman and Deal (1984, 1991a, 1994) provide a different perspective for examining organizations Bolman and Deal argue organizations should be viewed through four different frames or lenses. Framing and reframing organizational action captures the complexity of action and provides better understanding of organizational processes. Understanding of implementation of policies/programs also will benefit from the use of the four-frame approach.^ The goal of this research is to provide a better understanding of the implementation process by examining individual attitudes toward change, the dependent variable of this research, and studying the relationship between the dependent variable and frame. The research was conducted in two phases. In Phase One, a survey was sent to 306 school administrators and teachers in magnet programs in Dade County, Florida. The survey instrument was composed of 55 questions including six from Bolman and Deal's Leadership Orientation Survey (1988) and 38 questions about organizational change. In Phase Two, more in-depth analysis of four school was conducted, to further explore the relationship between frame and attitude toward change.^ The results revealed that frame was a factor in explaining differences in personal Attitude Toward Change and Comfort Level with Change. Individuals using the symbolic frame had more positive attitudes toward change and were also more comfortable with change. The results of Phase Two of the research partially supported this finding in that the most fully implemented program was the product of an administrator who had chosen the symbolic frame. ^

The object binary interface: C++ objects for evolvable shared class libraries

Object-oriented design and object-oriented languages support the development of independent software components such as class libraries. When using such components, versioning becomes a key issue. While various ad-hoc techniques and coding idioms have been used to provide versioning, all of these techniques have deficiencies - ambiguity, the necessity of recompilation or re-coding, or the loss of binary compatibility of programs. Components from different software vendors are versioned at different times. Maintaining compatibility between versions must be consciously engineered. New technologies such as distributed objects further complicate libraries by requiring multiple implementations of a type simultaneously in a program. This paper describes a new C++ object model called the Shared Object Model for C++ users and a new implementation model called the Object Binary Interface for C++ implementors. These techniques provide a mechanism for allowing multiple implementations of an object in a program. Early analysis of this approach has shown it to have performance broadly comparable to conventional implementations.

El consumo tradicional de los nuevos medios. Análisis de la usabilidad de las publicaciones autóctonas para tableta en el contexto universitario español y brasileño

Esta investigación aborda el consumo que los jóvenes universitarios de España y Brasil realizan de las publicaciones para tabletas. A través del estudio de seis casos –las revistas españolas Don, VisàVis y Quality Sport, y los vespertinos brasileños O Globo a Mais, de Río de Janeiro; Estadão Noite, de Sao Paulo; y Diário do Nordeste Plus, de Fortaleza– se aplica una metodología cualitativa, el test de usabilidad, para detectar qué aspectos ralentizan y entorpecen la navegación en las nuevas generaciones de usuarios de medios móviles. A pesar de la influencia de las revistas impresas en la configuración de las publicaciones para tableta, los datos muestran que el usuario necesita “entrenarse” para conocer unas opciones de interacción a veces poco intuitivas o para las que carece de la madurez visual necesaria. Por ello las publicaciones más sencillas obtienen los mejores resultados de usabilidad.

Jigsaw Java: Intelligent, Automated Marking

The popularity of Computing degrees in the UK has been increasing significantly over the past number of years. In Northern Ireland, from 2007 to 2015, there has been a 40% increase in acceptances to Computer Science degrees with England seeing a 60% increase over the same period (UCAS, 2016). However, this is tainted as Computer Science degrees also continue to maintain the highest dropout rates.
In Queen’s University Belfast we currently have a Level 1 intake of over 400 students across a number of computing pathways. Our drive as staff is to empower and motivate the students to fully engage with the course content. All students take a Java programming module the aim of which is to provide an understanding of the basic principles of object-oriented design. In order to assess these skills, we have developed Jigsaw Java as an innovative assessment tool offering intelligent, semi-supervised automated marking of code.
Jigsaw Java allows students to answer programming questions using a drag-and-drop interface to place code fragments into position. Their answer is compared to the sample solution and if it matches, marks are allocated accordingly. However, if a match is not found then the corresponding code is executed using sample data to determine if its logic is acceptable. If it is, the solution is flagged to be checked by staff and if satisfactory is saved as an alternative solution. This means that appropriate marks can be allocated and should another student have submitted the same placement of code fragments this does not need to be executed or checked again. Rather the system now knows how to assess it.
Jigsaw Java is also able to consider partial marks dependent on code placement and will “learn” over time. Given the number of students, Jigsaw Java will improve the consistency and timeliness of marking.

Digital accessibility challenges: the impact of locality, usability and technology

Abstract: It is estimated that 1 in 5 will, at some point in their lives, experience a long-term illness or disability that will impact their day to day lives. Access to digital information and technologies can be life changing and a necessity to fully participate in education, work and society. Specialist assistive technologies, such as screen readers, have been available for many years and are now built-into operating systems and devices. In addition, web accessibility standards have been compiled and published since the advent of the World Wide Web over two decades ago. However, internet use by people with disabilities continues to lag significantly behind those with no disability and use of assistive technologies remains lower than should be the case with tools often abandoned. In this seminar we will talk about our work to identify digital accessibility challenges; the barriers experienced by those with disabilities and how computer scientists can play a part in removing obstacles to access and ease of use. We will discuss some of our projects focussing on: • Development of assistive technologies for niche groups of users, • improving accessibility standards to cover a wider range of disabilities, • creating accessibility training resources for developers and stakeholders • embedding accessibility practice within development projects.

“It’s the People That Drive It”: Motivating and Supporting Collaborative Data Use Practices in Three Teacher Education Programs

Thesis (Ph.D.)--University of Washington, 2016-08

The Effect of Psychological Distance on Willingness to Engage in Ideologically Based Violence

Research on the cognitive and decision-making processes of individuals who choose to engage in ideologically based violence is vital. Our research examines how abstract and concrete construal mindsets affect likelihood to engage in ideologically based violence. Construal Level Theory (CLT) states that an abstract mindset (high-level construal), as opposed to a concrete mindset (low-level construal), is associated with a greater likelihood of engaging in goal-oriented, value-motivated behaviors. Assuming that ideologically based violence is goal-oriented, we hypothesized that high-level construal should result in an increased likelihood of engaging in ideologically based violence. In the pilot study we developed and tested 24 vignettes covering controversial topics and assessed them on features such as relatability, emotional impact, and capacity to elicit a violent reaction. The ten most impactful vignettes were selected for use in the primary investigations. The two primary investigations examined the effect of high- and low-level construal manipulations on self-reported likelihood of engaging in ideologically based violence. Self-reported willingness was measured through an ideological violence assessment. Data trends implied that participants were engaged in the study, as they reported a higher willingness to engage in ideologically based violence when they had a higher passion for the vignette's social issue topic. Our results did not indicate a significant relationship between construal manipulations and level of passion for a topic.

A Pre-processing Moving Mesh Method for Discontinuous Galerkin Approximations of Advection-Diffusion-Reaction Problems

We propose a pre-processing mesh re-distribution algorithm based upon harmonic maps employed in conjunction with discontinuous Galerkin approximations of advection-diffusion-reaction problems. Extensive two-dimensional numerical experiments with different choices of monitor functions, including monitor functions derived from goal-oriented a posteriori error indicators are presented. The examples presented clearly demonstrate the capabilities and the benefits of combining our pre-processing mesh movement algorithm with both uniform, as well as, adaptive isotropic and anisotropic mesh refinement.

Front end development for building automation systems using JavaScript Frameworks

Automation technologies are widely acclaimed to have the potential to significantly reduce energy consumption and energy-related costs in buildings. However, despite the abundance of commercially available technologies, automation in domestic environments keep on meeting commercial failures. The main reason for this is the development process that is used to build the automation applications, which tend to focus more on technical aspects rather than on the needs and limitations of the users. An instance of this problem is the complex and poorly designed home automation front-ends that deter customers from investing in a home automation product. On the other hand, developing a usable and interactive interface is a complicated task for developers due to the multidisciplinary challenges that need to be identified and solved. In this context, the current research work investigates the different design problems associated with developing a home automation interface as well as the existing design solutions that are applied to these problems. The Qualitative Data Analysis approach was used for collecting data from research papers and the open coding process was used to cluster the findings. From the analysis of the data collected, requirements for designing the interface were derived. A home energy management functionality for a Web-based home automation front-end was developed as a proof-of-concept and a user evaluation was used to assess the usability of the interface. The results of the evaluation showed that this holistic approach to designing interfaces improved its usability which increases the chances of its commercial success.

Validazione di una metodologia per la simulazione della cavitazione in iniettori per applicazioni automobilistiche

Al giorno d’oggi, il primo obiettivo dell’industria automotive è quello di ridurre il consumo di carburante e migliorare la qualità del processo di combustione, al fine di soddisfare i limiti di emissioni imposti, senza penalizzare le performance dei motori. In questo scenario, il comportamento dinamico dello spray gioca un ruolo cruciale, ed è risaputo che esso dipenda anche dal processo di cavitazione all’interno di ogni singolo foro iniettore. L’appropriata predizione dello sviluppo di tale fenomeno è fondamentale per comprendere e controllare le caratteristiche delle spray nei canali iniettori e consentire una più accurata progettazione degli iniettori. In questo meccanismo, le simulazioni CFD ricoprono un ruolo di grande importanza, a causa delle dimensioni ridotte caratteristiche dei fori iniettori. Questi infatti non risultano spesso adatti ad un’analisi sperimentale dettagliata e precisa, e nel caso lo fossero, la valutazione è limitata a pochi casi, essendo le attività sperimentali complesse ed onerose. L’analisi computazionale presenta quindi vantaggi come una sostanziale riduzione del tempo e dei costi impiegati, non richiedendo infatti la costruzione e l’utilizzo di impianti appositi o prototipi. Lo scopo principale di questo progetto consiste nella validazione di un codice CFD capace di modellare la cavitazione, al fine di applicarlo successivamente ad un iniettore reale. Tale modello è stato validato tramite confronto con dati sperimentali su un flusso cavitante attraverso un ugello ideale. Tra tutti i software commerciali disponibili, è stato scelto CONVERGE poiché innovativo nella generazione automatica della griglia e dettagliato nell’analisi chimica, permettendo di gestire geometrie di motori molto complesse. È stato quindi ritenuto appropriato valutare la validità di tale codice nella modellazione della cavitazione, poiché potrebbe dimostrarsi rilevante nello studio futuro dei motori a combustione interna.

Solid state micro and nanopore sensors for single entity detection

A general description of the work presented in this thesis can be divided into three areas of interest: micropore fabrication, nanopore modification, and their applications. The first part of the thesis is related to the novel, reliable, cost-effective, potable, mass-productive, robust, and ease of use micropore flowcell that works based on the RPS technique. Based on our first goal, which was finding an alternate materials and processes that would shorten production times while lowering costs and improving signal quality, the polyimide film was used as a substrate to create precise pores by femtosecond laser, and the resulting current blockades of different sizes of the nanoparticles were recorded. Based on the results, the device can detecting nano-sized particles by changing the current level. The experimental and theoretical investigation, scanning electron microscopy, and focus ion beam were performed to explain the micropore's performance. The second goal was design and fabrication of a leak-free, easy-to-assemble, and portable polymethyl methacrylate flowcell for nanopore experiments. Here, ion current rectification was studied in our nanodevice. We showed a self-assembly-based, controllable, and monitorable in situ Poly(l-lysine)- g-poly(ethylene glycol) coating method under voltage-driven electrolyte flow and electrostatic interaction between nanopore walls and PLL backbones. Using designed nanopore flowcell and in situ monolayer PLL-g-PEG functionalized 20±4 nm SiN nanopores, we observed non-sticky α-1 anti-trypsin protein translocation. additionally, we could show the enhancement of translocation events through this non-sticky nanopore, and also, estimate the volume of the translocated protein. In this study, by comparing the AAT protein translocation results from functionalized and non-functionalized nanopore we demonstrated the 105 times dwell time reduction (31-0.59ms), 25% amplitude enhancement (0.24-0.3 nA), and 15 times event’s number increase (1-15events/s) after functionalization in 1×PBS at physiological pH. Also, the AAT protein volume was measured, close to the calculated AAT protein hydrodynamic volume and previous reports.

Proof Explanation in the DR-DEVICE System

Trust is a vital feature for Semantic Web: If users (humans and agents) are to use and integrate system answers, they must trust them. Thus, systems should be able to explain their actions, sources, and beliefs, and this issue is the topic of the proof layer in the design of the Semantic Web. This paper presents the design and implementation of a system for proof explanation on the Semantic Web, based on defeasible reasoning. The basis of this work is the DR-DEVICE system that is extended to handle proofs. A critical aspect is the representation of proofs in an XML language, which is achieved by a RuleML language extension.
