There has been an ongoing debate on quality and what constitutes quality improvement in healthcare for several decades. Several authors identify that defining quality is an important part of that debate, yet recognise that quality is defined differently by different interests (Caper, 1988; Harteloh, 2003). Harteloh's distinction between quality as a property (a descriptive approach) and quality as a category of judgment (a prescriptive approach) has influenced the conception of quality as a property of participation emerging in this research. This is in stark contrast to the wide spread prescriptive approach set out in published accounts of quality and quality improvement. In the mainstream management literature, conventionally organisations are understood as systems and this conceptualisation underpins many published considerations of quality. In this way of thinking, those involved in leading quality improvement are thought to operate as autonomous individuals who design improvement tools and control improvements according to plans. It is taken for granted that it is possible for a powerful individual to step out of the organisational system and treat it as an object for manipulation and change, following the diagnosis of problem areas and gaps. Yet at other times that autonomous individual becomes part of the system and is subject to manipulation and change by others. As with much of the literature of change management, this approach sets "thought" before "action". In other words, "thought" is understood as the formulation of a plan and "action" is the implementation of that plan. In this thesis, it is my contention that this way of thinking leads to a privileging of the more mechanical and cybernetic elements of quality improvement - such as tools and techniques of waste elimination and fault detection, and, of particular interest in this thesis, the use of national targets in the public sector. My research is underpinned by a complex responsive processes perspective (Stacey, Griffin and Shaw, 2000). Central to this theory of human interaction is the importance of understanding everyday experience from the perspective of inquiring into “…just what is it that we are doing in our groups or in our organisations that leads to emergent patterns that are our experience…” (Stacey, 2003c: 32). In this thesis, I take up a key question raised by Stacey (2006) concerning how those working in the public sector institutions are operationalising central government governance requirements. I explore my experience of working locally with nationally determined performance targets for access to emergency care. I argue for consideration of quality improvement as a cult value along the lines defined by Mead (1923). In conceptualising quality improvement in this way, my inquiry focuses on what happens as we try to make sense of the ways in which our daily activities are being influenced by competing ideologies, by power relations that are played out, and by the enabling and constraining aspects of going on together in patterns of conversation. These are the complex social processes of working with targets I refer to in the title of this thesis. It is my contention that this perspective draws attention to quality as a property of our own participation as managers, rather than the more usual exhortations to look for the next tool for instilling quality into the organisation. As such, I argue that this research makes an important contribution to the ongoing debate on quality, as well as managerial practice. I propose that the participative and socially reflexive nature of the qualitative methodology involved provides a practical example of Mode 2 research, addressing what MacLean, MacIntosh and Grant (2002) identify as a current gap in the literature. Finally, I posit a potential contribution to policy making seeking to address a growing recognition from some policy makers regarding what is now being seen as an increasing problematic reliance on traditional, modernist assumptions of programmatic change.

I have lived through nineteen mergers and acquisitions and without moving companies, have signed eight employment contracts, all following M&As. Only two of the eight companies still trade, the others went bankrupt or shut down. My roles have been in engineering, sales, middle management and more recently a contributor at meetings where M&As were discussed and advisors attended. Despite professional advice, these M&As rarely turned out as planned including the envisaged growth and improvements. Often matters got worse, even for top executives. Yet, in both the literature and the way that people talk, businesses and individuals are portrayed as separate entities, M&As are aimed at changing only the businesses and are routinely associated with growth and improvements. My experience of M&As includes confusion about power and powerlessness, a sense of loss of valued relationships, identity issues and idealization of merged businesses. Using a narrative methodology and taking my experience seriously (Stacey and Griffin, 2005), I explore change and continuity through M&As and the experiencing of organizational upheavals. I also explore change in the idea of M&As and how we think of them. Drawing on complex responsive processes theory, I argue that we can enhance our understanding of change and continuity through M&As by exploring our experience of local interaction. Combined organizations as patterns of local interactions between people where these patterns emerge and evolve in the interplay of intentions, plans, actions and choices of all involved includes those between members of the merged organizations and between them and advisors, mediators, shareholders, competitors, customers, regulators and the media. To say that combined businesses emerge in this interplay is to understand change and continuity in terms of these evolving patterns of local interaction. These patterns include interpretations and conversations reflecting our ideologies, power relations, identities, idealizations and expectations about M&As. My expectations and reflections were influenced by and influence the discourse about M&As which I argue as social object evolves through our complex responsive processes of relating. Idealization of merged businesses, professional advice, the mainstream view of M&As as growth and improvement which amounts to ‘putting thought before action’ (Griffin, 2002: 25), all emerge and evolve through local interaction validating reflexive exploration of experience to enhance our understanding of change and continuity through M&As.

Thesis advisor: Irwin Blumer / This case study examined the creation of a collaborative learning environment focused on the development of teacher attitudes, perceptions, and practices that are culturally responsive. Sixth and eighth grade teachers collaborated in small groups over the course of a school-year, focusing on dialogue, activities, and readings related to race and culture. The ways in which teachers involved in the study developed thinking in regards to their cultural awareness, sense of efficacy, and instructional practices played central roles in this study. This qualitative case study was conducted by the school principal, who was a participant-observer. Data collection instruments included pre-program interviews, mid-program reflective journals, post-program interviews, and researcher field notes. Prior to the start of the program, teachers expressed that they rarely spoke with students and peers about issues related to race and culture, provided minimal accommodations for students of color within the classroom setting, exhibited mixed beliefs in terms of their abilities as teachers to meet the learning needs of students of color, and had a limited understanding of their own racial identities. As a result of their participation in the Culturally Responsive Teaching Program, most teachers experienced growth in terms of their perceptions of the their own racial identity development, efficacy, and increased their sense of comfort and desire to speak with students and peers about issues related to race and culture. Implications for practice include the need for; courageous leadership, persistence, promotion of the development of racial identity, understanding of racial identity development, promotion of collaboration, advancement of transformational learning, and the development of multi-dimensional learning experiences. Limitations of this study include the researcher's role as school principal and participant-observer, small sample size, and relatively short study duration. Recommendations for future research include increasing the sample size and program duration, investigation of changes in student experiences as a result of teacher participation in a similar program, and investigating the effect of a similar program when focused upon particular racial and cultural groups, as opposed to the broad approach utilized within the Culturally Responsive Teaching Program. / Thesis (EdD) — Boston College, 2009. / Submitted to: Boston College.

Smartphone usage is higher than ever and the number is steadily increasing, but not all websites on the Internet are adapted for use on smartphones. This study set out to find common and proven guidelines from the current scientific literature and create a guide on how to best adapt a desktop website to be optimized for use on smartphones. Areas of research were usability, readability and energy saving. A literature review of the body of data on the subject was reviewed and the result was put in a list of guidelines. The guidelines were used to compare the desktop version versus the smartphone version on 5 frequently visited websites.    The result was summarized with a score for each website and their respective solution for displaying components on small screens was noted. A prototype website was constructed in two versions: one responsive and one unresponsive. The prototype website’s different versions were then tested by a group of testers. The result of the tests concluded that the guidelines raised user satisfaction and readability. Sufficient energy saving metrics could not be extracted in the way design and usability was tested and had to be excluded from the testing.    The list of guidelines showed that there are solutions for solving readability, usability issues  and energy-saving issues on smartphones. The testing concluded that there was an increase in text readability and usability of the website when the guidelines were implemented. Further testing of energy saving must be conducted to test the validity of the remaining untested  guidelines.

Bacterial infections are a serious problem for patients with burns and other wounds. Such burn wound infection accounts for the pathogenic bacteria by colonising onto burned areas. Therefore, the need for detection and inhibition of such bacterial colonisation requires a methodology for sensing/killing pathogenic bacteria. This research project aims to design a ‗smart‘ wound dressing system which can respond to the microbiological environment of the wound via a simple colour change and will release antimicrobials only when required. Two strains of pathogenic bacteria Staphylococcus aureus (MSSA 476) and Pseudomonas aeruginosa (PAO1) were used in the study. The non-pathogenic bacterium E.coli (DH5α) was used as a control organism as it does not secrete virulence factors and therefore does not lyse membranes of vesicles. The key contributions of this thesis are outlined below. Firstly, an initial responsive nanocapsule system was studied. The fundamental work with giant unilamellar vesicles proved such a responsive system can provide antimicrobial properties when antimicrobial agents were encapsulated within the vesicles. Secondly, partially polymerised vesicles—polydiacetylene/phospholipid vesicles were then developed to improve vesicle stability. The vesicle system was optimised by varying molar concentration of diacetylene monomers (TCDA) in order to obtain relatively stable vesicles as well as sensitivity to the toxins secreted by the pathogenic strains. Measurements proved that the polydiacetylene/phospholipid vesicles can respond to pathogenic bacteria when fluorescent dye/antimcirobials were encapsulated in the vesicles. Finally, a simple prototype dressing was constructed. Plasma polymerised maleic anhydride (pp-MA) deposited onto non-woven polypropylene was shown to be a good method to stabilise vesicles via covalent bonding. Vesicle adhered to pp-MA non-woven polypropylene showed the ability to inhibit/kill the pathogenic strains, quantified by the Japanese Industry Standard assay and also gave a fluorimetric colour response in the presence of pathogenic bacteria when a fluorescent dye is encapsulated within vesicles. Other simple prototypes were also attempted by using hydrogels (gelatine and collagen) to maintain vesicle stability as well as promote tissue healing.

Soft robots present the opportunity to extend the capabilities currently demonstrated within the field of robotics. By utilizing primarily soft materials in their construction, soft robots are inherently safe to operate around humans, can handle delicate tasks without advanced controls, and are robust to shocks and impacts during deployment. While proof-of-concept devices have been demonstrated successfully, there remains a need for widely applicable, reliable soft robotic components. This dissertation presents sensors to reliably measure the large deformations exhibited in soft robotic structures and responsive structures enabled by variable stiffness materials that can switch from flexible to stiff on-demand. By characterizing the sensors from the material level, through the manufacturing, to the completed functional device, the fabrication processes can be depended upon to produce sensors with predictable, reliable performance. The sensors were applied to various soft robotic systems through implementation on the surface of the structures to measure surface strains, and embedded in the body of the robot to measure body deformations. The sensory feedback was used to reconstruct the state of and to perform closed-loop control of the soft robot's position. Variable stiffness materials that switch from rigid to soft through application of heat were leveraged to create responsive structures that can be deformed or reconfigured on-demand. This capability is necessary for soft robots to exert load onto the external environment and enables a wider range of interactions with target objects. The work presented in this dissertation furthers the field of soft robotics by illustrating a path toward proven, reliable soft sensors for measuring large strains and variable stiffness materials to create responsive structures.

The Internet is gradually expanding to many new devices, in addition to its original native environment that was the Personal Computer. This wave started with mobile devices and as we enter the Internet of Things era, connectivity is possible from cars to light switches. One of the first devices, to follow mobiles, is the Television. Connectivity and two-way interaction on the TV device has in fact started even in the first days of the medium, but had failed to make it widely available, due to technological limitations of the past. Now, this has changed, with the Smart TV devices that can utilize the fast internet connections that are available in most developed countries. However, even though the technology and devices are now widely available there are still challenges in order to make the vast Internet and web content available in the Smart TVs. These challenges, have a familiar resemblance to what happened a few years ago, when internet connectivity was introduced on the mobile phone. Although, it was "feasible" to access any webpage from your mobile device, the experience for the user was often very frustrating, due to many factors, that derived from the fact that the web was designed for large screens and mice of the desktop computers, not the small touch screens and limited hardware of the phone. Nonetheless, these obstacles were successfully overcome, by introducing techniques and methodologies (e.g. Responsive Web Design) to make the web more mobile-friendly and also work from the manufacturers to improve their devices to this direction as well. The success of these actions is now evident, since the access to the web from mobile devices has surpassed the PC, and it is now a standard practice for every new website to be mobile-friendly. In this research work, we will attempt to do one very significant step towards this direction for the Smart TV. In other words, to discover what has to be done to make the web more TV-friendly. To do this, we explore many different TV devices from several manufacturers and see their similarities and differences. We explore numerous user studies and surveys to discover what is the problem in the Web experience on the TV, so that we can propose solutions to make web content TV-friendly. Based on these findings, we design prototypes and put them to the test on different devices and userevaluation. Finally, we propose a set of guidelines, that web designers can apply on their websites to make them TV-friendly, in the hope to introduce the first step towards a friendlier internet era for the TV.

The exponential increase in the annual number of women released from prison in the United States underscores the imperative need for holistic, fully integrated gender-responsive reentry services. The purpose of this qualitative study is to understand the unique contributions of paraprofessional staff charged with meeting the multi-layered, programmatic needs of women offenders with co-occurring disorders. A qualitative, evidence-based interview guide was used to analyze the utilization of gender-responsive services provided by 21 paraprofessionals throughout four Southern California Counties. The findings indicate that while paraprofessional staff members understand the concept and approach of gender-responsive oriented services, there remain significant programmatic barriers that not only impair the reduction of recidivism rates, but also undermine successful community reentry efforts. These findings support the inherent micro and macro-based approaches to social work that acknowledge a systems approach to improving outcomes for women offenders striving toward health and wellness.

How do elementary educators approach cultural diversity within international school settings? How do North American teachers negotiate the tensions and experiences they have as cultural agents living abroad while valuing the cultural identities of the students they serve? This study describes how international teachers' unique positions, experiences and perspectives affect their attention to cultural diversity within their classrooms. Sociocultural theory frames this study with emphasis on personal and professional identities, narrative inquiry and culturally responsive teaching. I interweave narrative inquiry and ethnographic research methods as theoretical and methodological frameworks. I interviewed and observed the 3 North American educators in their elementary classrooms in an American school in China over several weeks. Data collected in this study included interview transcripts, artifacts from the school and classrooms, photographs and field notes. I also weave my own stories from my experiences as an international teacher throughout the study. The Atlas TI qualitative computer program assisted the constant-comparative analysis process. Grounded and axial coding revealed a pattern across participants' stories and approaches to cultural diversity. All three teachers authored stories from their cross cultural experiences that informed their identities as educators. The teachers questioned their cultural agent role, reflected on their responses and took action in their teaching to be culturally responsive. The approaches each teacher implemented to be responsive to the cultural worlds in their classroom related to their cultural agent identities in their personal stories of cross-cultural experiences. Findings indicated that teachers were more likely to be culturally responsive in their teaching when they implemented a constructivist educational philosophy in their classrooms. This study reconceptualized cultural responsiveness to include the diverse cultural worlds of the student, teacher and international school setting.

Di-block copolymer of poly[methacrylic acid-block-2-(diethylamino)ethyl methacrylate] [P(MAA-b-DEA)] with narrow molecular weight distribution was synthesized using the atom transfer radical polymerization (ATRP) technique. The micellization behavior of the P(MAA-b-DEA) copolymer in aqueous solution at room temperature and different pH values were examined by potentiometric and conductivity titration, UV-Visible spectrophotometry, ¹H-NMR, static and dynamic laser light scattering. At low pH (< 4.2), core-shell micelles were formed with MAA core and protonated DEA shell. At moderate pH values, the polymer precipitated from water and formed a cloudy solution, where the polymer chains aggregated into larger particles resembling that of a hard sphere induced by electrostatic interactions. At high pH (> 9.5), core-shell like micelles consisting of hydrophobic DEA core and ionized MAA shell were re-established. / Singapore-MIT Alliance (SMA)
