The flow of Chinese international students to the US is a long-standing phenomenon that has lasted for more than a century. Such popularity has been growing on a larger scale in the last two decade until the Covid-19 pandemic. Wondering on such sustained and augmenting heat of migration and mobility to the US, this study takes a biographical approach to explore the lives and experiences of today’s Chinese international students in the US by examining their mobility motives, lived experiences, reflections and reflexivities on their international mobility, and their future imagining and projecting.
Among the extant studies, very few takes a holistic approach to investigate the whole international mobility experiences of Chinese international students. Most of them only focus on their horizontal relocation but overlook their vertical temporalities. This study introduces two backbone theoretical frameworks of youth transition to adulthood and migration/mobility to construe the biographical experiences of today’s Chinese international students in the US with a central aim of inquiring into what role international mobility plays in their transitions to adulthood and how they wield agency to navigate their mobility trajectories against contextual and structural constraints. Through international mobility, Chinese international students experience ‘double’ social changes from the rapidly-changing China to the ever-changing America and from the past to the future. Therefore, by examining how Chinese international students make transitions to adulthood, this study can also reflect the changes to social conditions in both China and the US and even to the extent of the whole world.
Assuming that today’s Chinese international students growing up in a fast-changing society could be vastly different from their predecessors not long ago, this research adopts a qualitative research paradigm using in-depth interviews to collect empirical data in order to provide a rich understanding of the multiplicity and breadth of participants’ individual experiences, with various reflexive representations of the individuals’ narratives at the core of the study. Following an interpretivist-constructivist approach to analyze empirical data, this study finds out that today’s young Chinese international students practice international mobility to the US mainly for escaping social control in China and for an alternative transition process in a different social condition in which they believe they will be able to enjoy the course of studying, living and exploring, and after years of mobile lives in the US they incorporate spatial mobility into their imagining and projecting for future transition outcomes-making. And the analysis reveals that they value mobility highly and display an acute awareness of both the advantages and challenges of their mobile lives and refer to their lived experiences in both China and the US for their decision-making process concerning their future mobility trajectories in the hopes of securing both ‘good’ transition processes and ‘good’ transition outcomes. The significance of this study reaches beyond offering a landscape of today’s Chinese international students in the US to the extent that valuable theoretical implications can be contributed to the currently vigorous debate on youth transitions to adulthood while being on the move.The flow of Chinese international students to the US is a long-standing phenomenon that has lasted for more than a century.

Thesis (MBA)--Stellenbosch University, 2005.ENGLISH ABSTRACT: The aim of this research project is to describe the journey to a process enterprise. This research project is a combination of work been done by Dr. Michael Hammer about the process enterprise and the author. The bulk of the theory of the research project is the following courses that were presented by Dr. Hammer in Boston, USA: • The Transition to the Process Enterprise: Strategies and Techniques. • Managing the Process Enterprise: Principles and Practices. • Process Design and Implementation: Reengineering and Change Management. A model of the research project is designed by the author who includes a theoretical summary of the two books written by Dr. Hammer about the process enterprise: • The Agenda. • Beyond Reengineering. A further model is designed which form part of the research project model, and is a roadmap to implement the process enterprise concepts. This model is based on the process lifecycle and covered all the material of the three courses presented by Dr. Hammer. The process lifecycle is the journey to a process enterprise which will result in improved sustainable enterprise or business performances if implemented. The sub parts of the process lifecycle model are the following: • Building commitment for the process enterprise. • Mobilisation to perform processes. • Process metries, prioritisation and targets. • Plan the process work. • Work the process plan. • Persuade, sell and align. • Change management. The different chapters of the process lifecycle are tools and techniques that must be implemented in a chronological order to become a process enterprise. The implementation of these tools and techniques will transform a traditional functional enterprise to a process enterprise. The last part of the research project described the practical experience by Rosh Pinah Zinc Corporation on their journey to a process enterprise. Rosh Pinah Zinc Corporation is a zinc mine owned by the South African diversified mining house, Kumba Resources. Rosh Pinah Zinc Corporation delivered spectacular results since the implementation of the process enterprise concept.
AFRIKAANSE OPSOMMING: Die doel van die navorsings projek is om die transformasie na 'n proses gedrewe organisasie te beskryf. Die navorsings projek is 'n kombinasie van werk wat gedoen is deur Dr. Michael Hammer en die outeur. Die grootste gedeelte van die teorie is afkomstig vanaf die volgende kursusse wat deur Dr. Hammer aangebied is in Boston, USA: • The Transition to the Process Enterprise: Strategies and Techniques. • Managing the Process Enterprise: Principles and Practices. • Process Design and Implementation: Reengineering and Change Management. 'n Model is ontwerp vir die navorsings projek wat 'n teoretiese opsomming insluit van die twee boeke wat geskryf is deur Dr. Hammer oor die proses gedrewe organisasie. Die twee boeke is die volgende: • The Agenda. • Beyond Reengineering. 'n Verdere model is ontwikkel deur die outeur wat deel vorm van die navorsings projek model wat 'n padkaart is om die proses gedrewe organisasie konsepte te implementeer. Die model is gebaseer op die proses iterasies en bevat al die materiaal van die kursusse wat deur Dr. Hammer aangebied is. Die proses iterasies is die transformasie na 'n proses gedrewe organisasie wat sal lei tot verbeterde volhoubare besigheids prestasie, indien die konsepte geimplementeer word. Die sub gedeeltes van die proses iterasie model is die volgende: • Verkry toewyding vir die proses gedrewe organisasie. • Mobiliseer om die prosesse te implementeer. • Proses metings, prioritisering en doelwitte. • Beplan die proses werk. • Werk die proses plan. • Oorreed, verkoop en belyn. • Veranderings bestuur. Die verskillende hoofstukke van die proses iterasie is gereedskap en tegnieke wat in 'n kronologiese volgorde geimplementeer moet word om te transformeer na 'n proses gedrewe organisasie. Die suksesvolle implementering van die gereedskap en tegnieke sal 'n tradisionele funsionele organisasie transformeer na proses gedrewe organisasie. Die laaste gedeelte van die navorsings projek beskryf die praktiese ervaring van Rosh Pinah Zinc Corporation met hul implementering van die proses gedrewe organisasie konsepte. Rosh Pinah Zinc Corporation is 'n sinkmyn wat deur die gediversifiseerde mynhuis, Kumba Resources, besit word. Rosh Pinah Zinc Corporation het uitstekende resultate gelewer sedert die implementering van die proses gedrewe organisasie konsepte.

MethaneSummary The behavior of gas filtration combustion waves in the low-velocity regime has been studied experimentally with variation in the parameters of the gas flow and porous medium. It is shown that in transition processes there may be quenching or formation of a stable combustion-wave structure that does not correspond to the initial or final conditions. A nontrivial type of transition process accompanied by spatial transfer of the combustion zone is found.

Software handover is a de facto process in all software organizations. It is one of the most business critical and complex processes. It is also one of the most diverse processes, and thereby, one of the most difficult processes to define. Despite this, software handover is not well recognized within the academia. Right now, there are no software handover process models whatsoever although software organizations desperately need guidelines for how to perform this important and critical task. To aid them in defining their handover process models, we are in the process of creating Evolution and Maintenance Management Model (EM 3 ): Software Handover focusing on handover (alias transition) of a software system from developer to maintainer. In this paper, we evaluate one of the EM 3 components, Management and Administration (MA), addressing activities for planning and controlling the transition process, its schedule, budget and resources. We do it within 29 organizations. Our primary goal is to find out whether the component is realistic and whether it meets the needs and requirements of the software industry today. Using the feedback from the industry, we tackle process diversity using the C ontext- D riven P rocess Orchestration M ethod (CoDPOM).QC 20120223

Despite the fact that a handover process is just as frequently performed as any development process, little is known about it. Still, it is regarded as one of the lifecycle processes that is not well explored and defined. In this paper, we study the handover process within eighteen companies with the purpose of demarcating its scope within software lifecycle. Our goal is to find out how industry understands handover process and how it places it within software lifecycle. As a result, we have identified seven different scope contexts for the handover process. We have also provided evidence of its wide lifecycle span and its overlap with development, predelivery and postdelivery maintenance processes.© 2010 IEEE. Personal use of this material is permitted.

Full textAbstract:
Climate change has been recognised as one of the biggest challenges of our time. To prevent further climate change impacts, nations at COP21 further stressed the need to mitigate their greenhouse gas emissions enough to prevent dangerous temperature rise and to adapt societies to become more resilient. Municipals have been found important actors in this transition due to their power to inflict change on a local level. However, there is a lack of methods to assess how transition is made due to the fact that transition is a fairly new approach to managing climate change combined with a lack of completed transitions in municipalities. The purpose of this study is to explore the use of indicators as a method to assess municipal transition processes. Focusing on two Swedish municipalities that have been deemed vulnerable but at the same time apt to combat climate change, this study uses a triangulation of methods that are divided into two phases. The first phase uses a literature review in order to create a scientifically based list of transition indicators. The second phase uses document analyses and interviews in order to test the indicators and analyse transition process on a local level. The study revealed that there are multiple barriers and triggers for transition such as conflicting interests, economic factors, political steering, knowledge building- and awareness and long term perspectives, but that there also exist important tools for municipal transition in the form of networks through multi-level collaborations and plans/objectives. The findings in this study also suggests that the use of indicators as a method to assess transition could be viable, but that it is limited due to its contextual nature and lack of successful transitions to compare with.Klimatförändringar har ansetts vara en av de viktigaste utmaningarna i vår tid. För att förhindra att vidare skador av klimatförändringarna kom nationer som deltog i COP21 överens om att minska sina växthusgaser tillräckligt mycket för att förhindra farliga temperaturförhöjningar och att anpassa sina samhällen till resilienta enheter. Kommuner anses vara viktiga aktörer i denna omställning då de har makt att påverka förändringar på en lokal nivå. Dock saknas metoder för att bedöma hur omställning utförs då omställning är ett nytt angreppssätt kombinerat med en brist på genomförda omställningar. Syftet med denna uppsats är att utforska användningen av indikatorer som metod för att bedöma omställningsprocesser. Genom att använda en triangulering av metoder som delats upp i två faser fokuserar studien på två svenska kommuner som har fastställts som känsliga inför klimatförändringarna men även att ha förmågan att hantera dem. Den första fasen består av en litteraturstudie som skapade en vetenskaplig grund som berörde en global och nationell nivå. Den andra fasen bestod av en dokumentsanalys och intervjuer för att utforska omställningsprocesser på en lokal nivå. Studien visar på att det finns flera barriärer och drivkrafter för omställning som konkurrerande intressen, ekonomiska faktorer, politisk styrning, kunskaps byggande- och medvetenhet och långsiktighet men även att det fanns verktyg som var viktiga för kommunal omställning som nätverk genom samarbeten på olika nivåer och planer/mål. Slutligen visar även studien på att användningen av indikatorer som metod för att bedömma omställning skulle kunna vara möjligt men att begränsningar finns då metoden dels är kontextberoende men även att det är svårt att göra jämförelser då ingen fullförd omställning har skett.

The transitional process to retirement by today's professional women is an issue of great significance. Beginning in the 1960s, these women became the first generation en masse to form long-term careers and to join the professional ranks. Retirement is now affecting over seven million women who are age 55 or older. A void exists in literature concerning these women's experiences as they approach retirement. Their pre-retirement transitions and decision-making process have not been previously addressed. This study addressed the void and through qualitative research, employed a multiple-case study with a phenomenological frame. Through in-depth interviews, the data collected addressed professional women's pre-retirement decision-making. A five-phase working model was developed that illustrates the transitions to retirement of professional women.Ph. D.

Team selection processes are an inherent part of high performance sport and may impact athletes’ sport engagement and psychological adjustment (Samuel & Tenenbaum, 2011a). The purpose of this program of research was to advance understanding of high performance developmental and elite athletes’ experiences with significant team selection processes. Two prospective-longitudinal studies were conducted to achieve this objective. The first study examined how elite athletes negotiated the 2012 Olympic team selection process from an Interpretative Phenomenological Analysis perspective (Smith, Flowers, & Larkin, 2009). Three primary themes emerged from analysis of the interviews including the Olympic goal, navigating the Olympic team selection process, and moving on from the Olympics. Results suggested that participants organized their athletic and vocational endeavours around their goal of being selected to compete in the Olympic Games, demonstrating significant investment and sacrifice. To cope with non-selection, athletes reappraised where the 2012 Olympic Games fit within their athletic careers, engaged in new and meaningful athletic, social, and vocational goals, and emphasized the prominence of social and vocational identities unrelated to sport. Study two examined how stress and adaptational processes were impacted by the 2013 Canada Summer Games (CSG) selection process. Multilevel modeling was employed to investigate changes in cognitive appraisals, emotions, coping, sport engagement, athletic goal progress, and life satisfaction in relation to athletes’ CSG selection status. Findings suggested that the CSG tryout had a meaningful impact on athletes as evidenced by changes in emotions, cognitive appraisals, and athletic goal progress in relation to their selection status. However, the CSG selection process did not affect athletes’ sport engagement or life satisfaction. Collectively, results from both studies indicated that athletes reappraised selection processes over time and varied in their emotional responses to team tryouts, highlighting the importance of investigating intrapersonal change and interpersonal differences associated with team selection events. Findings also suggested that the stage of sport career influenced the meaning athletes attached to specific selection processes and the degree to which these events influenced their life as a whole.Education, Faculty of

Full textAbstract:
As information technology’s role in the modern economy grows in importance, society makes exponentially greater demands on the diversity and quality of the software being produced. To develop high quality software, a good software development process is important. Software process improvement is about improving software quality and reliability, employee and client satisfaction, and return on investment. From the mid 1990s onwards, agile software development has been challenging the traditional (plandriven) view of software development. Agile software development accords primacy to uniqueness, ambiguity, complexity, and change, as opposed to prediction, verifiability, and control. The fundamental differences between traditional and agile software process improvement and the lack of research on these differences, gave rise to the overall problem addressed by this thesis: “How does Software Process Improvement work change with the introduction of agile software development in plan-driven companies?” This thesis focus on answering the following research questions: What characterizes SPI in plan-driven companies?, What characterizes SPI in change-driven companies?, and What are the key SPI challenges when implementing change-driven development? This thesis summarizes six years of studies in three small and medium-sized companies in Norway. The overall research method has been the same: case study and action research. Qualitative data in the form of interviews and participant observations constitute the most important source of evidence. Through a synthesis of contributions from twelve papers, ten key findings connected to the three research questions has been identified. To summarize, software process improvement in plan-driven companies is characterized by a participative bottom-up approach when creating company best practice, focus on project management support, high individual autonomy, and long cycles of single-loop learning; the goal of reflection on projects is to improve future projects. Software process improvement in changedriven companies is characterized by supporting the whole team and not only project management, practice is improved by short cycles of single-loop learning, and the goal of reflection in projects is to improve the current project. Finally, software process improvement challenges while implementing change-driven development are to increase redundancy to create conditions for the team to self-manage, to learn how to learn, and to perceive the adoption of change-driven development as a large, long-term organizational change project. The overall contribution of this thesis is that it shows empirically that the goal of software process improvement changes from improving processes to improving practice. However, achieving this goal is challenging when only part of the organization is involved in the change. Also contributions are deep knowledge about software process improvement in plan- and change-driven small- and medium-sized companies, knowledge about software process improvement challenges when implementing change-driven development, and increase the body of literature on longitudinal action research

Studying the interaction of people with the objects
around them is essential to designers. A designer must
study in detail: the hold, the fit in the hand, the effect of
movement, the placement, and the juxtaposition and
relation of objects to one another. Insight derived from
such investigation determines the form given to an object.
However, the answer is not a static or rote response to
function. The designer searches to balance meaning with
practicality, while simultaneously pushing the boundaries
of perception to make people reconsider how and why
objects exist. Questions of changing social customs,
habits, rituals and traditions are explored. The resulting
form reflects the manner in which the object is used.
Shape is given to ritual. The intent is for design to reflect
the order of day to day existence. It is not important
whether an object is a recognizable form or whether it
looks like its predecessors. However, upon
consideration one should realize the form is correct. The
object possesses meaning; it is appropriate for its time.
The process is on-going, requiring the designer to
continually re-evaluate and re-define the human condition
by assessing the world we make and how we exist within
it. One pursues better ways to facilitate daily life, never
becoming complacent with existing products. More
acutely, it is requisite for the designer to maintain an
ongoing dialogue with their work-an empirical process of
evaluating and analyzing past objects in order to make
the decisions that allow the beginning of the next.Master of Architecture

Connolly, Christopher James. "Transition expertise : cognitive factors and developmental processes that contribute to repeated successful career transitions amongst elite athletes, musicians and business people." Thesis, Brunel University, 2011. http://bura.brunel.ac.uk/handle/2438/7656.
Full textAbstract:
This thesis examines the nature of transition expertise which enables individuals to make repeated successful transitions over the course of their career. It addressed four areas that contribute to transition expertise: 1) cognitive flexibility that enables the generalisation of expert knowledge and processes; 2) inferential and inductive cognitive mechanisms that enable expertise to be generalised; 3) personal intelligences that are used to support transitions; and 4) practical intelligence as it supports performance contextually during transitions. The study used retrospective interviews to gather data from elite performers in three fields who had made successful career transitions: sports people who become national coaches or heads of national bodies; successful musicians who become heads of faculty or principals of a conservatoire; successful business people who become senior vice presidents or CEOs. Participants were able to generalise expert knowledge and processes beyond their primary domains, contrary to widely held views about the domain specificity of expertise. Cognitive flexibility enabled this generalisation and was developed through broad based training, early exposure to multiple domains and the early use of generative cognitive processes during the development of primary domain expertise. Inductive, inferential and analogical cognitive mechanisms were the main tools through which expertise was generalised during transitions. Personal intelligence contributed to transition expertise. Intrapersonal intelligence enabled individuals to understand how their abilities, values and motivations shaped their career progression. Interpersonal intelligence enabled individuals to respond effectively to the requirements of their peers, direct reports, stakeholders and organisational context. Contrary to expectations, self regulatory processes did not play a central role in the management of transitions. Practical intelligence enabled transition expertise. It involved more than applying subject-area and tacit knowledge. It encompassed the abilities to: identify and resolve problems; manipulate environmental objects in the form of administrative tasks, schedules and plans; utilise resources in terms of people and materials; and shape their environment, corporate structures and culture. Transition expertise develops and evolves over the course of a career as it uses convergent and divergent cognitive processes, inductive mechanisms, personal awareness and cognitive pragmatics to address issues of increasing scope and implication. While motivational factors, self belief and personality resiliency are important contributors to transition expertise they did not form part of this study.

Full textAbstract:
Over the last few decades the interests of statistical physicists have broadened to include the detailed quantitative study of many systems - chemical, biological and even social - that were not traditionally part of the discipline. These systems can feature rich and complex spatiotemporal behaviour, often due to continued interaction with the environment and characterised by the dissipation of flows of energy and/or mass. This has led to vigorous research aimed at extending the established theoretical framework and adapting analytical methods that originate in the study of systems at thermodynamic equilibrium to deal with out-of-equilibrium situations, which are much more prevalent in nature. This thesis focuses on a microscopic model known as the asymmetric exclusion process, or ASEP, which describes the stochastic motion of particles on a one-dimensional lattice. Though in the first instance a model of a lattice gas, it is sufficiently general to have served as the basis to model a wide variety of phenomena. That, as well as substantial progress made in analysing its stationary behaviour, including the locations and nature of phase transitions, have led to it becoming a paradigmatic model of an exactly solvable nonequilibrium system. Recently an exact solution for the dynamics found a somewhat enigmatic transition, which has not been well understood. This thesis is an attempt to verify and better understand the nature of that dynamical transition, including its relation, if any, to the static phase transitions. I begin in Chapter 2 by reviewing known results for the ASEP, in particular the totally asymmetric variant (TASEP), driven at the boundaries. I present the exact dynamical transition as it was first derived, and a reduced description of the dynamics known as domain wall theory (DWT), which locates the transition at a different place. In Chapter 3, I investigate solutions of a nonlinear PDE that constitutes a mean-field, continuum approximation of the ASEP, namely the Burgers equation, and find that a similar dynamical transition occurs there at the same place as predicted by DWT but in disagreement with the exact result. Next, in Chapter 4 I report on efforts to observe and measure the dynamical transition through Monte Carlo simulation. No directly obvious physical manifestation of the transition was observed. The relaxation of three different observables was measured and found to agree well with each other but only slightly better with the exact transition than with DWT. In Chapter 5 I apply a numerical renormalisation scheme known as the Density Matrix Renormalisation Group (DMRG) method and find that it confirms the exact dynamical transition, ruling out the behaviour predicted by DWT. Finally in Chapter 6 I demonstrate that a perturbative calculation, involving the crossing of eigenvalues, allows us to rederive the location of the dynamical transition found exactly, thereby offering some insight into the nature of the transition.

This thesis develops a grounded theory of the personal experience of being retired, for twelve women who previously had jobs of a professional/semi-professional status. The focus of the study is on evidence of the ways in which the self-awareness of the participants is challenged and adapts to the changed situation of their lives. The longitudinal study (Study 1) comprises a core group of six women, interviewed three times over 18 months starting soon after retirement. Study 2 comprises a group of four women interviewed once, at a time 6 to 9 years after retirement. Study 3 comprises a group of two women, interviewed once, at a time more than 10 years after retirement. Case studies form the empirical basis of the work, in-depth interviews being the main technique used. Self-descriptive instruments of narrative exercises and diary accounts support interview data. Measures of depression (Beck, 1990; 1987), and self-esteem (Battle, 1981; 1992), are also utilised. Data was analysed using Grounded Theory (Glaser and Strauss, 1967; Glaser, 1978; Strauss, 1987; Strauss and Corbin, 1990). A process model of the transition of the Self in retirement emerged from the data. This model shows a process of fragmentation and subsequent re-integration of the Self during the retirement transition. Data from the core group of six women initially identify seven components of the Self: 'Known Self, 'Adjusting Self, 'Defining Self, 'Discovered Self, 'Ageing Self, 'Adapting Self and 'Community Self. A process of re-examination of these components of the Self by participants facilitates a process of reintegration of the Self. This process involves gradual reintegration of the seven initially identified component fragments back into the Self that was known and familiar, the Known Self. Negative aspects of ageing, and the potential threat these aspects of ageing are to the maintenance of the Known Self, are acknowledged and incorporated into self-definition ('Threatened Self and 'Self in Limited Time'). Data from studies 2 and 3 confirm the aspects of'Known Self, 'Threatened Self, and 'Self in Limited Time' to be aspects of the Self that are carried forward in defining the Self in later life. The fragmentation of the sense of Self was experienced in varying degrees by participants, and was evidenced most clearly in the women's sense of identity and selfdefinition. Positive aspects involved in the process of adjustment of the Self to retirement included the realisation that the Known Self has continuity, together with the potential for freedom and new discoveries. Maintenance of the Known Self, however, was found to be more difficult without the medium of the work role for its expression. The proposal that the move from work to retirement involves a psychosocial transition (Parkes, 1971; 1975; Theriault, 1994) is supported by the present study. Also supported are findings by Antonovsky and Sagy (1990), Mann (1991), and Taylor Carter and Cook (1995), indicating that retirement involves re-definition and can have a disruptive influence on a woman's sense of Self. The process model of the transition of the Self in retirement that emerged from the data further develops the work of Antonovsky and Sagy (1990), which identified the developmental outcome of psychological reintegration following retirement. The present investigation develops the process of this re-integration. Hanson and Wapner's (1994) findings, that women experienced that their sense of Self changed with retirement, are also further developed by the present study whereby a more detailed analysis of the process and particulars of the changes in the sense of Self are uncovered.

Las celdas solares orgánicas se han convertido en una promesa para la producción de energía a bajo costo, y su potencial se refleja en los enormes esfuerzos para mejorar su eficiencia. En los últimos 30 años, esta tecnología ha crecido enormemente, con prototipos de laboratorio mostrando eficiencia mayor que 10 % . El continuo desarrollo de polímeros semiconductores, materiales de amortiguamiento, y el conocimiento profundo sobre el intercambio electrónico en las interfaces, han sido las principales razones de este crecimiento.
Sin embargo, la mejora de esta tecnología a estados de producción de bajo coste como tecnologías de impresión R2R es el objetivo, y el desarrollo de materiales de procesamiento de baja temperatura es el reto a superar.
En este trabajo, se ha explorado en profundidad la aplicación de los óxidos de metales de transición como capas tampón electrónicos como TiO2 , ZnO como capas de transporte de electrones , y V2O5 , NiO como capas de transporte de huecos. También muestra el desarrollo de una tinta base agua con procesamiento a baja temperatura de V2O5 para aplicaciones R2R, así como la aplicación de película de NiO sinterizado a baja temperatura (350oC) y la caracterización mediante diferentes técnicas espectroscópicas.

In the last 30 years, this technology has grown enormously; nowadays the state of the art is showing efficiencies higher than 10%. The continuous development of semiconducting polymers, buffer materials, and the depth knowledge about the electronic exchange at the interfaces, have been the principal reasons of this growing. Nevertheless, upgrading this technology to low cost production states like roll to roll printing technologies is the goal, and the development of low temperature processing materials is the challenge to overcome.

Full textAbstract:
Today's processes of cultural globalization involve three major trends: (I)the global expansion of transnational communications conglomerates; (2) the global implementation of market-oriented cultural policies; and (3) the global diffusion of new communication technologies. These processes have set in motion complicated consequencesa nd prompted a range of national responses.B oth China and Taiwan, the two locations which embody the Asian region's largest cultural formation, have experienced major shifis in their internal political and economic organisation and been significantly influenced by these interlinked global processes since the early 1980s. Taking the national film industries in both locations as a case study, this thesis examines the impact of globalisation on the organisation of national cultural production and distribution, and explores the uses of film in representing shifting conceptions of national culture and identity.

This thesis reports an interview-based study of thirty female-to-male (FtM) transsexual individuals. These participants were divided into three groups of ten according to their transitional status: 'pre-transitional', 'transitional and 'post-transitional. Interviews were carried out utilising an extensive semi-structured interview schedule and were recorded. Tapes together with field notes from each interview were that transcribed. The thirty transcripts were then subjected to a detailed review and analysis. A range of issues were identified in relation to the notion of FtM transsexual identity as this was experienced through the processes of FtM transition. The conclusions drawn identified a number of substantive areas of insight into the FtM transsexual condition, each of which have implications for an understanding of: coping with a threatened identity; passing; trust; factors relating to and effects of disclosure following these individuals' decision to embark cm transition; issues pertaining to transition, and attitudes of the medical profession toward transsexualism, among others. Some policy issues were also identified indicating scope for interentive measures geared at facilitating the life circumstances and transsitional passage of FtM transsexual people.

Full textAbstract:
Strategy processes and internal actors’ practices are crucial for organisations given their dynamic environment. Strategy processes including formulation, implementation, and evaluation have been treated as mutually exclusive, making how strategy is actually transitioned between them a matter of major concern (Whittington, 2007; Sorooshian and Dodangeh, 2013; Leonardi, 2015). Equally, particular groups of internal actors and their strategic practices have previously been researched in isolation from one another without expressing how they collectively interact to ultimately give strategy processes (Vaara and Whittington, 2012; Engen and Magnusson, 2015; Friesl and Kwon, 2016). These processes and practices have barely been researched in the public sector, and this in turn contextualises this research to study strategy transition processes and practices enacted in public sector organisations. Drawing on strategy-as-practice and Social Practice theory as meta-theoretical lenses, this research explores the dynamics of the strategy transition process stage by revealing the social practices of internal actors and other influential factors. A pragmatism approach was adopted for this research. The primary data collection was obtained through 27 semi-structured interviews with respondents from a single case study followed by survey of 381 respondents across five case organisations in Kuwait. The research identified four factors that interact and contribute to the complexity of the strategy transition process and practices of actors in the process. These are in order of significance; process design, actors’ social interactions, strategic awareness, and role of leadership. In relation to the social interaction and leadership factors, the research found that strategy practices can be influenced by the societal culture inherited by actors. Equally, it was revealed that the control mechanism adopted for the strategy transition process contributed to the enhancement of the strategy transition process design and strategic awareness between actors. Additionally, the dynamic interaction between these factors was found to affect strategy practice, which in turn either enables or impedes the smooth transition of organisational strategies from the formulation to implementation phases. The research also contributes to the understanding of Social Practice theory by introducing the interactivity as a cognitive construct to its boundary. Hence, the study and its findings extend our understanding of the contextual social practices that could help to enhance the strategy transition process among internal actors.

Full textAbstract:
The aim of this thesis is to produce a substantive grounded theory of junior-to-senior transition and as a result of this work, to provide knowledge and guidance for coaches, sport psychologists and other personnel supporting young aspirant athletes. Underpinned by a social constructionist philosophy, the research programme was designed to capture and interpret the social world of the participants and to interpret the perceptions derived from their own lived experience of the transition. The thesis consists of three studies which, in a concatenated programme of research, are predicated one upon another. In order that understanding in social research can be advanced, the development of theory requires several rounds of fieldwork, analysis and publication (Stebbins, 1992,2006). Thus the building of theory took place over the initial two studies, the first of which involved the in-depth interviewing of nine participants from individual sports (M age = 24.5 years, S. D. = 4.3 years). As a consequence of this exercise, rich data were collected, depicting the participants' experiences of the juniorsenior transition. Grounded in these data, a preliminary model of junior-to-senior transition was constructed using Strauss and Corbin's (1998) guidelines for grounded theory analysis. More specifically, the resultant model revealed a cyclical process: of learning, identity development and progress at transition. Inception of the process is characterised by immersion in the post-transition environment during the pre-transition phase, in which significant observational learning occurs via the use of more senior role models. This process leads to the identification of discrepancies between the actual (or junior) and ideal (or senior) self. This promotes a period of adjustment in which the behaviours relevant to senior status are incorporated within the self, bringing about a sense of readiness, or ability to cope with the transition. In essence, the athletes had sought to structure their pre-transition environment to represent that which they would encounter post-transition, thereby generating stability for their self-identity. The modification of identity, through the adjustment of behaviours and roles, predicted a competitive breakthrough, at which point the athletes began to think about the subsequent step at senior level, and hence the cycle of immersion, learning and adjustment continued.

Full textAbstract:
The Cambodian genocide and its aftermath are unique in that key leaders are on trial thirty years after their regime fell. This creates particular problems : the UNbacked trials (ECCC) assume the normative aims of the transitional justice paradigm, but exist in context of multiple ‘transitions’ preceding or running concurrent to them, creating complex competing and complementary ideas about what constitutes ‘justice.’ Over the previous thirty years transition was a social process; alongside legalistic input it included (and still includes) religious discourse, ceremony, ritual and modes of expression not employed or recognised in courts. This thesis concerns the many and dynamic ways in which the concept of justice is discussed, narrated and manifested both inside and outside formal mechanisms. The thesis concludes that the meaning of justice resides in a nexus of memory, time and imagination emergent from the act of telling the story, in a way that effectively lodges it within intergenerational cultural memory. Justice is a process without fixed ends. Justice necessarily involves narrative; the way the past is narrated is key to the application and realisation of justice. Expanding on Lyotard’s theory of Grand Narratives, I contend that justice narrates itself through ‘phrase regimes’ which I explore within three legalistic processes : the People’s Revolutionary Tribunal , the trial of Pol Pot , and the narrative streams emerging from the hybrid United Nations/ Royal Government of Cambodia Extraordinary Chambers in the Courts of Cambodia (ECCC) . I contend each of these demands narrative conformity to ideological and political templates (Marxism, Liberalism). I further contend that these grand narratives collapse in Cambodia. Their limitations are exposed on encounter with what Ricoeur calls ‘the small voices of history.’ In ‘small’ narrations, via socio-cultural processes such as religious ritual, legalistic narratives of justice may overlap, but the individual voices often transgress, or are marginalised by, the grand narratives. The latter part of the thesis goes on to explore transition and justice from ‘outside’ legalistic mechanisms, and discusses ideas of justice arising from within the society in whose interests these mechanisms allegedly act. Through observing and attending numerous religious ceremonies and personally collecting 59 ethnographic interviews with monks, former KR cadres, witnesses, civil parties, historical and cultural figures from multiple communities in 10 provinces in the country I have established some basis for situating individual voices into a specifically Cambodian intellectual context.

Although there exist some people management process models related to the education and training of software engineers, there are no process models that are adapted to specific software engineering contexts and processes. In this paper, we suggest a set of education and training activities that are applicable in the context of a handover process. We then evaluate these activities within twenty organizations. Although our results reveal great diversity of using these activities, they still show that they are realistic and appropriately mirror the industrial status within a software handover context.© 2011 IEEE.

Estudamos um sistema de partículas a tempo discreto cuja dinâmica é a seguinte. Considere que no instante inicial sobre cada inteiro não negativo há uma partícula, inicialmente inativa. A partícula da origem é ativada e instantaneamente ativa um conjunto aleatório contíguo de partículas que estão a sua direita. Como regra, no instante seguinte ao que foi ativada, cada partícula ativa realiza esta mesma dinâmica de modo independente de todo o resto. Dizemos que o processo sobrevive se em qualquer momento sempre há ao menos uma partícula ativa. Chamamos este processo de Firework, associando a dinâmica de ativação de uma partícula inativa a uma infecção ou explosão. Nosso interesse é estabelecer se o processo tem probabilidade positiva de sobrevivência e apresentar limites para esta probabilidade. Isto deve ser feito em função da distribuição da variável aleatória que define o raio de ação de uma partícula. Associando o processo de ativação a uma infecção, podemos pensar este modelo como um modelo epidêmico. Consideramos também algumas variações dessa dinâmica. Dentre elas, variantes com partículas distribuídas sobre a semirreta dos reais positivos (nesta vertente, existem condições para as distâncias entre partículas consecutivas) e também com as partículas distribuídas sobre vértices de árvores. Estudamos também para esses casos a transição de fase e probabilidade de sobrevivência. Nesta variante os resultados obtidos são funções da sequência de distribuições dos alcances das explosões e da estrutura dos lugares onde se localizam as partículas. Consideramos também variações do modelo onde cada partícula ao ser ativada, permanece ativa durante um tempo aleatório e nesse período emite explosões que ocorrem em instantes aleatórios.We studied a discrete time particle system whose dynamic is as follows. Consider that at time zero, on each non-negative integer, there is a particle, initially inactive. A particle which is placed at origin is activated and instantly activates a contiguous random set of particles that is on its right. As a rule, the next moment to what it has been activated, each active particle carries the same behavior independently of the rest. We say that the process survives if the amount of particles activated along the process is infinite. We call this the Firework process, associating the activation dynamic of a particle to an infection or explosion process. Our interest is to establish whether the process has positive probability of survival and to present limits to this probability. This is done according to the distribution random variable that defines the radius of infection of each active particle, Associating the activation process to an infection, we think this model as a model epidemic. We also consider some variations of this dynamic. Among them, variants with particles distributed over the half line (there are conditions for the distances between consecutive particles) and also with particles distributed over the vertices of a tree. We studied phase transitions and the correspondent survival probability. In this variant the results depend on the sequence of probability distributions for the range of the explosions and on the particles displacement. We also consider a variation where each particle after activated, remains active during a random time period emitting explosions that occur in random moments.

Full textAbstract:
Business processes are essential parts of any organisation which define the series of steps performed to achieve their goal. Business processes are normally designed manually by business experts who have deep knowledge of the activities performed in the organi-sations. This knowledge is commonly described in a declarative way as business rules. Organisations have to cope with large numbers of business rules and existing regulations governing the business in which they operate. Such rules are difficult to maintain due to their size and complexity, and it is increasingly challenging to ensure that each business process adheres to those rules. As such, extraction of business processes from rules has three clear advantages: (1) visualisation of all possible executions allowed by the rules,(2) automated execution and compliance by design, (3) identification of “inefficiencies” in the business rules. Extraction of business processes from rules set is a time and re-source consuming process. In this thesis, we have investigated two approaches to extract the business processes from the declarative specification of it.
In the first approach, we have investigated the application of constraint satisfaction based planners to automatically extract the business process from the sets of rules specifying it. For this purpose, we have developed a constraint-based automated planner named Transition Constraints for Parallel Planning (TCPP). As a constraint-based planner, it encodes a planning problem as a constraint satisfaction problem and then extracts the plan from the solution to that. TCPP constructs its constraint model from a redefined version of the domain transition graphs (DTG) of a given planning problem. TCPP encodes state transitions in the redefined DTGs by using table constraints with cells containing don’t cares or wild cards. TCPP uses Minion the constraint solver to solve the constraint model and returns a parallel plan. We empirically compare TCPP with the other state-of-the-art constraint-based parallel planners. Experimental results we have conducted show that our developed planner outperforms existing constraint-based planners for a large set of benchmarks. Then we have described the specification of the activities and regulations in the organisation in PDDL, the language used for describing planning problems, and the business process is extracted from the resulted plan.
In the second approach, to handle uncertainties which may occur during execution of the process and to have a comprehensive business process, we have also designed a formal method to visualise and operationalise sets of rules as a verifiable business process that is compliant by design, which allows us to analyse all possible execution paths. Additionally, we formally prove correctness of the business processes generated by our method. The approach is implemented in a tool and evaluated on both performance and correctness, showing that even for highly complex sets of rules the approach performs well and outperforms a well-known state-of-the-art approach. Evaluation on a real-life process shows the feasibility of the presented approach.Thesis (PhD Doctorate)

O funcionamento de detectores fotocondutivos se baseia na geração de corrente elétrica por fotoexcitação de portadores de carga. Neste trabalho, estudamos os diversos processos que contribuem para a geração de corrente em fotodetectores intrabanda (BC) e construímos um método de investigação para revelar, dentre as diferentes possibilidades, os processos que resultam na emissão eletrônica em um dispositivo concreto. Uma vez estabelecida uma metodologia, passamos ao estudo de um caso particular: um fotodetector baseado em pontos e poços quânticos acoplados, com picos de absorção no infravermelho médio. Através da comparação de espectros de absorção e fotocorrente, medidos por espectroscopia de transformada de Fourier, e de simulações computacionais para o cálculo das forças de oscilador, indicamos as transições óticas e os processos de transporte eletrônico envolvidos na fotocondutividade do dispositivo.
The operation of photoconductive detectors is based on the generation of current through photoexcitation of charge carriers. In this work, we study the various processes that contribute to the generation of current in intraband (CB) photodetectors and build a method of investigation to reveal, among the different possibilities, the processes that actually result in electron emission in a particular device. After establishing a methodology, we apply it to a case study, more specifically, a dot-in-a-well (DWELL) photodetector with absorption peaks in the mid-infrared. By comparing absorption and photocurrent FTIR spectra as well as oscillator strength calculations performed by a computer simulation of the structure, we have approached the optical transitions and electron transport processes involved in the device s photoconductivity.

Full textAbstract:
In this thesis, we study some geometrical aspects of metric measure spaces (Rn, psi1/2 , mu)where mu is a locally finite regular Borel measure and a metric on psi1/2 which arises from a continuous negative definite function psi : Rn → R which satisfies psi(xi) ≥ 0 with psi(xi) = 0. This study is motivated by the investigation of a transition density estimate for pure jump processes on a general metric measure space. To gain a better insight into the behaviour of transition functions of symmetric Levy processes in this general setting, it seems desirable to understand geometrical properties of their underlying state spaces. More precisely, we show completeness of the metric spaces (Rn, psi1/2) and study under which circumstances open balls Bpsi(x,r), x ∈ Rn, r > 0, with respect to this metric are convex. Moreover, we focus on conditions of the metric measure spaces (Rn,psi1/2 ,mu) for the balls to satisfy the volume growth property [equation] for mu-almost all x ∈ Rn, 0 < r < R and a constant Cpsi(x,R)≥1. Finally, we show that the homogeneity property of a metric measure space can be applied to our case and provide some results associated with the construction of a Hajlasz-Sobolc space over (Rn,psi1/2, lambda(n)),where lambda(n) denotes the n-dirnensional Lebesgue measure.

For individuals with disabilities the transition from school to adopting adult roles within the community often presents numerous challenges. In a sample of pre-service education teachers, perceptions of school to community transitions of students with disabilities were investigated. Pre-service education teachers completed a three-page questionnaire in order to gather information about their knowledge of the transition planning process. The questionnaire consisted of fifteen questions plus four demographic questions, through which pre-service teachers' prior knowledge on transitions and of the transition planning process was assessed. The results highlighted the lack of knowledge and inconsistent perceptions that pre-service education teachers possess regarding the transition planning process. Pre-service teachers were not provided with training in transition planning, and as a consequence were not sufficiently informed about their roles and responsibilities in the process. These findings highlight the need for a definitive legislative definition and framework to inform pre-service training.Pour les personnes handicapées, la transition de l'école à la vie active dans la communauté présente souvent de nombreux défis. Grâce à un échantillon d'enseignants en formation, on voulait étudier la manière dont ces transitions sont perçues. On a demandé à un groupe d'enseignants en formation de remplir un questionnaire de trois pages pour apprendre ce qu'ils savaient au sujet de la préparation d'un plan de transition. Le questionnaire, constitué de quinze questions ainsi que de quatre questions démographiques, cherchait à déterminer ce que les enseignants savaient déjà au sujet des transitions et de la préparation de plans de transitions. Les résultats ont souligné le manque de connaissance et les impressions variées que détiennent les enseignants en formation concernant les plans de planification. Les enseignants en formation n'avaient pas appris comment préparer les plans de transition, et par conséquent, ils n'étaient pas suffisamment renseignés sur leurs rôles et leurs responsabilités. Ces conclusions soulignent la nécessité de formuler une loi et des directives claires pour améliorer la formation de futurs enseignants.

This dissertation aims to study what approach given to human rights in the country's democratization process and how it reflected on the agenda of justice Brazilian transition. It is, therefore, the debates in the Constituent National Assembly of 1987-1988, in order to verify that the guidelines privileged in human rights protection harvest, the contexts to which they were associated and in which optical protection were conducted. The research assumption is that reading about these rights as gestated in the Constituent Assembly, had influence in dealing with transitional measures may provide or no idea of justice turned to the period of political transition. The transitional justice is therefore seen as the set of actions necessary to periods of change between regimes, through which it seeks to obtain responses from the States with regard to addressing the crimes committed by its agents in human rights violations sets. Admits that list the dimensions of memory, truth and justice, considered mandatory to the concretion of the transitional measures and evokes the need for a different understanding of that proposed by the procedural justice in the treatment of the victim. This study raises questions about how the conservative character incident about not addressing the issues related to transitional justice in the country at the time of political and democratic transition led to the delay of this discussion, its incompleteness and maintenance of various authoritarian structures within the state democratic Brazilian law. The research findings indicate that, while if all advances in the field of study of human rights portrayed in the 1988 Constitution itself, the transitional justice issue did not get the same dealings and is not therefore considered specifically in this set of rules. Despite what has been achieved, still follows incomplete and inert in view of the non-continuation of the transitional process.
Esta dissertação objetiva estudar qual a abordagem conferida aos direitos humanos no processo da redemocratização do país e de que modo ela repercutiu na agenda da justiça de transição brasileira. Vale-se, para tanto, dos debates ocorridos na Assembleia Nacional Constituinte de 1987-1988, com o intuito de verificar quais as pautas privilegiadas na seara de proteção dos direitos humanos, os contextos aos quais eles estiveram associados e sob qual ótica de tutela foram conduzidos. O pressuposto da pesquisa é o de que a leitura em torno desses direitos, tal como gestada na Constituinte, teve influência na forma de lidar com as medidas transicionais podendo propiciar ou não uma ideia de justiça voltada ao período da transição política. A justiça de transição é, portanto, encarada como o conjunto de ações necessárias aos períodos de mudança entre regimes, por meio do qual se busca obter respostas dos Estados no que tange ao enfrentamento dos crimes praticados por seus agentes em cenários de violações de direitos humanos. Admite nesse rol as dimensões da memória, da verdade e da justiça, consideradas obrigatórias à concreção das medidas transicionais e evoca a necessidade de uma compreensão diversa daquela proposta pela justiça procedimental no tratamento da vítima. O presente trabalho busca problematizar acerca de como o caráter conservador incidente sobre o não enfrentamento dos aspectos relacionados à justiça transicional no país no momento da transição político-democrática propiciou o retardamento dessa discussão, a sua incompletude e a manutenção de várias estruturas autoritárias dentro do Estado Democrático de Direito brasileiro. As conclusões da pesquisa indicam que, conquanto se verifiquem avanços no campo de estudo dos direitos humanos, retratados na própria Constituição de 1988, a temática da justiça de transição não obteve a mesma tratativa, não sendo, portanto, considerada de forma específica nesse regramento. A despeito das conquistas obtidas, ainda segue incompleta e inerte em vista do não prosseguimento do processo transicional.

Full textAbstract:
This thesis describes studies into Group 5 and Group 6 transition metal imido complexes, with particular emphasis on the development of complexes which can be applied to catalytic processes. Chapter 1 highlights the electronic and structural aspects of the imido and alkylidene ligands. The isolobal analogy between Group 4 bent metallocene. Group 5 half-sandwich imido and Group 6 bis(imido) metal fragments is outlined. In addition, Ziegler-Natta type a-olefin polymerisation and Ring Opening Metathesis Polymerisation (ROMP) are briefly reviewed. Chapter 2 describes initial screening of half-sandwich vanadium imido and chromium bis((^t)butylimido) dichloride complexes as catalyst precursors. Synthesis of the chromium bis(imido) dialkyl complex Cr(N(^t)Bu)(_2)(CH(_2)Ph)(_2) (1) is described, its conversion to a cationic alkyl species is probed and the polymerisation activity associated with the resultant compound is addressed. Finally this chapter details the synthesis and characterisation of a range of bis(adamantylimido) chromium complexes. Chapter 3 presents a synthetic entry point into the bis(arylimido) chemistry of chromium. The complex Cr(NAr)(_2)(NH(^t)Bu)Cl (12) is described (Ar = 2,6-(^i)Pr(_2)C(_6)H(_3)) and its conversion to the dichloride complex Cr(NAr)(_2)Cl(_2) (14) is examined. 14 forms the stable monoadduct with pyridine, the X-ray crystallographic study of which reveals a distorted square based pyramidal geometry about the chromium atom. The inclusion of the arylimido ligand at the metal centre allows stabilisation of the chromium bis- phosphine complexes Cr(NAr)(_2)(PMe(_3))(_2) (18) and Cr(NAr)(_2)(PMe(_2)Ph)(_2) (19). The reactivity of 18 towards unsaturated hydrocarbon substrates is briefly investigated. Chapter 4 focuses on the organometallic chemistry of the [Cr(NAr)(_2)] moiety. A range of dialkyl derivatives are isolated and the molecular structures of a selection are solved. The generation of the nascent species [Cr(NAr)(_2)(=CHCMe(_3))] is investigated and the conversion of Cr(NAr)(_2)(CH(_2)CMe(_3))(_2) (24) to Cr(NAr)(-2)(CHDCMe(_3))(C(_6)D(_5)) (25) is the subject of a kinetic study. In chapter 5, the ROMP of a series of amino acid derived norbomene monomers is studied. The resultant polymers are fully characterised and a brief molecular modelling study is carried out on representative polymers chain lengths. Chapter 6 contains experimental details to chapters 2-5.

Full textAbstract:
The ability to maximise learning efficiently is of
concern to all who are involved in an educational
environment. The process of learning that will
facilitate change is well documented. This documentation
suggests that:
(1) the understanding of what is occurring in the
process of change is essential for it to be
successful, and
(2) this process includes certain specific traits that
will facilitate change.
In this study, a design to acquire data from individuals
involved in this process of change is developed. To
acquire the data sought in this study, observation was
made of ten trainees involved in a skills enhancement
programme at Caloola Farm; a training centre sponsored by
the Federal Government and operated through the Baptist
Community Services (A.C.T.). The conclusion reached
supported the original premise that recognisable traits
exist and aid in the process of accepting change.

Full textAbstract:
This thesis presents research into the processes, practices and experiences of transition to secondary education in Northern Ireland from a children's rights perspective. Three aspects of the contemporary landscape of transition are considered: availability of school places and children's school choice aspirations; privately operated unregulated tests used for selection; and school level admissions arrangements which mediate transfer. The overarching aim of the thesis was to understand how inequities in each of these areas are potential barriers to children's enjoyment of their rights under the Convention on the Rights of the Child (United Nations, 1989). The mixed-methods study was conducted in three strands: a documentary analysis of school admissions policies for 205 academically selective and non-selective secondary schools offering admission in September 2014; a collaboration with children as research advisors to inform the purposes, processes and outcomes of the research which reflects a rights based approach; and a questionnaire of a broad sample of transition age children (10-12 years, n=1327) which extensively investigated their views and experiences of the policy and practice of transfer. The rights based, mixed methods approach was intentional, so as to place the voices of those directly affected by the transfer arrangements at the heart of the research. The findings illustrate serious inequities which represent a system-level failure to safeguard the child's right to education (article 28) under the CRC and according to Tomaševski's 4-As conceptual framework; that education should be available, accessible, acceptable and adaptable (2001). Aspects of transition procedures, such as the differential availability of school places and inconsistencies in school admissions requirements, limit school choice and contribute to inequitable access to secondary education. The assessment arrangements are shown to create additional complexities in admissions practices, resulting in differential experiences of access to academically selective schools. This thesis, by offering insight into children's experiences of admissions decisions across the full range of school types, demonstrates that the power of choice lies with schools. An analytical tool, developed as an outcome of this research, is proposed as a means to assess the extent to which transition arrangements are underpinned by respect for children's rights.
