根據Easley, Kiefer, O’Hara and Paperman (1996)所發展的模型，我們可以對台灣證券交易所上市的股票進行訊息交易的研究。我們的結果顯示，交易越活絡的股票含有訊息交易的機率越低；而這與Easley, Kiefer, O’Hara and Paperman的研究結果一致；換句話說，紐約證券交易所與台灣證券交易所的股票對於訊息交易都有類似的特性。因此，根據研究結果，沒有訊息的投資人應該多去交易較活絡或交易量較大的股票，因為這些股票含有訊息交易的機率較低。 / Following the empirical model developed by Easley, Kiefer, O’Hara and Paperman (1996), we have investigated the information content of the stocks on the TSEC. Our result reveals that more liquid stocks have the lower risk of informed trade than do less liquid stocks and this is basically consistent with the finding of Easley, Kiefer, O’Hara and Paperman. Stocks on the NYSE and the TSEC have similar characteristics of informed trade. Therefore, for uninformed traders, it is better for them to trade stocks which are more liquid and have higher trading volume.

Introduction and background Recruitment to cancer clinical trials needs to be improved, as does patient understanding about clinical trials, to enable patients to make an informed choice about whether or not to take part. The main reason that clinically eligible patients do not take part in clinical trials is because they refuse; poor understanding of the research has been associated with patient refusal. Audiovisual patient information (AVPI) has been shown to improve knowledge/understanding in various areas of practice but there is limited information about its effect in the cancer clinical trial setting, particularly in relation to recruitment rates. Understanding the research is necessary for informed consent, and it was hypothesised that if patient understanding about clinical trials was increased with AVPI, then this could result in a reduction in the number of patients refusing clinical trials, and therefore provide an ethical approach to improving recruitment. This study aimed to test the impact of an audiovisual patient information intervention on recruitment to randomised cancer clinical trials (refusal rates), patient understanding of the information given, and levels of anxiety. Reasons for patients’ decisions about trial participation were also assessed. Method An AVPI intervention was developed that aimed to address the common misconceptions associated with randomisation and clinical equipoise, as well as improve patient understanding generally of randomised cancer trials, and of other core clinical trial informational requirements, such as voluntariness. Patients were randomised to receive either AVPI in addition to the standard trial-specific written information, or the written information alone. A new questionnaire was developed to assess patient understanding (also referred to as knowledge) in the randomised trial setting and, following testing with patients and research nurses, this was shown to be reliable and valid. Patients completed self-report questionnaires to assess their understanding (new knowledge questionnaire) and anxiety (Spielberger State-Trait Anxiety Inventory), at baseline and after they had made their decision about clinical trial entry, when their perceptions of the intervention, as well as factors contributing to their decision were also determined (this tool incorporated Jenkins and Fallowfield’s (2005) questionnaire which assessed reasons for accepting and declining randomised cancer trials). Results A total of 173 patients with breast cancer (65%), colorectal cancer (32%) and lung cancer (3%) were entered into the main study. The median age was 60 (range 37-92 years). There was no difference in clinical trial recruitment rates between the two groups: 72.1% in the AVPI group and 75.9% in the standard information group. The estimated odds ratio for refusal (intervention/no intervention) was 1.19 (95% ci 0.55-2.58, p=0.661). Knowledge scores increased more in the intervention group compared to the standard group (U= 2029, p=0.0072). The change in anxiety score between the arms was also statistically significant (p=0.011) with anxiety improving in the intervention arm more than in the no-intervention arm. The estimated difference in the median anxiety change score between the groups is –4.6 (95% ci –7.0 to –2.0). Clinical trial entry was not influenced by tumour type, stage of cancer, age, educational qualifications or previous research experience, however, there was a modest association with deprivation status (p=0.046) where more affluent patients were the least likely to consent to a trial. Educational qualifications and stage of cancer were independently associated with knowledge: patients who were better educated had higher levels of knowledge about randomised trials, and patients who had limited stage of cancer had higher baseline knowledge than patients with advanced cancer. Acceptability of the intervention was high with 93% of those who watched it finding it useful, and 42% stating that it made them want to take part in the clinical trial. Personal benefit and altruism were key motivating factors for clinical trial participation, with reasons for refusal being less clear. Discussion and conclusions Although the potential for AVPI to increase clinical trial recruitment rates was highlighted in the literature, in this study, AVPI was not shown to have any effect on refusal rates to randomised cancer trials. However, by improving patient understanding prior to decision making, AVPI was shown to be a useful addition to the consent process for randomised cancer trials. AVPI addresses the fundamental ethical challenges of informed consent by improving patient understanding, and supports the ethical framework integral to Faden and Beauchamp’s (1986) theory of informed consent. The new knowledge questionnaire was shown to be a sensitive and effective instrument for measuring understanding of randomised clinical trials in the cancer setting, although it would benefit from further testing. The AVPI appears to reduce anxiety at the decision making time point and has been shown to be an acceptable medium for patients. This study confirms existing findings from studies assessing factors affecting decision making, with personal benefit and altruism being key motivating factors, and reasons for refusal being less clear. The need for further qualitative work in this area is highlighted to gain a deeper understanding of what is important to patients, in terms of why they refuse clinical trial participation. Implications for practice and further research Several implications for practice have been identified, including using AVPI as part of the standard information package for patients considering randomised cancer trials, and focussing on patient and staff education in this area. The knowledge questionnaire could be introduced to routine practice as a tool to determine patient understanding prior to decision making, allowing clinicians the opportunity to correct any misconceptions prior to consent. Further research focussing on AVPI specific to individual trials would be helpful, to determine if a more customised approach would be of benefit in terms of clinical trial recruitment. The importance of studying other aspects of the consent process such as the interaction between the clinician and the patient, in addition to more detailed exploration of the factors affecting patients’ decisions were highlighted.

There is very little theoretical literature about theatrical improvisation as it connects to ideas and practices of relating and specifically to ideas and practices of social work relating. This thesis involves efforts to theorize moments of relating – of being with others – in improvisation. A group of hospital social workers and a group of PhD social work research students participated in the study. The participants took part in improvisational workshops designed specifically for the study, as well as one-on-one and group interviews. This thesis explores what was created between research participants in improvisational workshops: the response-ability to and for others; an experience of grappling with the desire for control; and an embodied apprehension of interdependence. The study demonstrates an embodied and uncomfortable experience of the dominance of individualism in our relating. The study also demonstrates ways in which the art of theatrical improvisation can allow us to take up the transformative promises of social constructionism in social work relating. The thesis aims to make living space for central social constructionist concepts such as mutual constitution and interdependence – to explore and consider what happens when we fully recognize and carry these out in our practices of relating. Providing a different way into these central social constructionist concepts, this study contributes to arts-informed research, teaching and practice. More specifically, the research shows how the art of improvisation can provide transformative possibilities for social work pedagogy and the social work classroom. / Thesis / Doctor of Philosophy (PhD) / This thesis involves efforts to theorize moments of relating – of being with others – in improvisation.

Sjukskrivningstalen är höga bland terapeuter och handledning ses som ett viktigt stöd i både utbildning och yrkesutövning. Trots det så har få metoder fokuserat på terapeuters egna upplevelse av handledning. Några nya metoder med syfte att öka intrapersonell och psykologisk kapacitet hos terapeuter i arbete med klienter är Deliberate Practice (DP), Feedback Informed Treatment (FIT) och Self-compassion (SC). Under 2018 användes dessa metoder av två handledare som handledde sex studentterapeuter under utbildning. Denna studie undersöker hur studentterapeuterna upplevde det nya arbetssättet. Studien bygger på semistrukturerade intervjuer som har analyserats tematiskt utifrån en induktiv ansats. Resultatet visar att ett upplevelse- och feedbackbaserat arbetssätt uppfattades som tidseffektivt, strukturerat och målinriktat. Detta skapar aktivitet och delaktighet, en stark gruppdynamik samt god allians med handledarna vilket ger gott klimat för inlärning och utveckling. Några negativa aspekter på arbetssättet är att det är tidskrävande, att fokusering på prestation och feedback upplevs som ett hinder som kan skapa stress, ångest samt en känsla av att utvärderingen inte blir rättvis. Sammantaget visar resultatet att arbetssättet uppfattas som gynnsamt för studentterapeuter i utbildningsterapi gällande utveckling av både terapeutiska färdigheter och intrapersonell kapacitet. En utmaning för arbetssättet är att handledningen är obligatorisk, hierarkisk och betygsgrundande. För att generera goda förutsättningar för arbetssättet behövs mer utrymme i utbildningen skapas, fördelarna med arbetssättet belysas och ett tillåtande klimat med fokus på allians mellan studenter och handledare upprätthållas. Därtill är det också viktigt att beakta studenternas förmåga att vara självmedkännande. / There are high rates of sick-leave among therapists and supervision is seen as an important support in both professional practice and during education. Despite this, there are few methods that focuses on therapists' experience of supervision. Some new methods with the aim to increase the intrapersonal and psychological capacity of therapists in work with clients are Deliberate Practice (DP), Feedback Informed Treatment (FIT) and Self-Compassion (SC). During 2018, these methods were used by two supervisors who supervised six student therapists during training. This study examines how the student therapists experienced the new way of working. To collect the data semi-structured interviews were conducted, to further be analyzed thematically based on an inductive approach. The result showed that an experience- and feedback-based approach was perceived as efficient, structured and goal-oriented. This created activity and participation, a strong group dynamic and a good alliance with the supervisors, which provided a good climate for learning and development. Some negative aspects of the work method were that it’s a time-consuming. Further, focusing on performance and feedback was perceived as an obstacle that could create stress, anxiety and a feeling that the evaluation was not fair. The result showed overall that the way of working was perceived as beneficial for student therapists in education therapy regarding the development of both therapeutic skills and intrapersonal capacity. A challenge is that supervision is mandatory, hierarchical and that it’s a graded task. In order to generate good conditions for the work method more available space is needed within program. The advantages of the method need to be highlighted and an open climate with focus on alliance between students and supervisors need to be maintained. It is also important to consider the students' ability to be self-compassionate.

Master of Landscape Architecture / Landscape Architecture/Regional and Community Planning / Mary C. Kingery-Page / The purpose of this study is to investigate and design public light art installations. The investigation consisted of evaluating select examples of public light installations in order to develop a typology, and designing two site-specific light art installations: one in Wichita, Kansas, and the other, in Denver, Colorado. Though public light art is found in most cities, its potential is often lost or unrecognized. In certain cases, public light art can be ‘plop art,’ which is plopped senselessly without much regard to context or experiential qualities. This project seeks to explore the different types of public light art and to find what approach or qualities should be considered when designing public light art. My approach can be described as artistic research. The methods include an apprenticeship to an artist, a precedent study, development of a light typology, an analysis of site and context, establishing a design matrix for two design projects, and an iterative process of making. Each of these methods were undertaken in order to effectively address my research question: What type of public light art is most appropriate for a specific site and how does it relate to creative placemaking? This project overlaps with a collective project group entitled Creative Place-Making, which is comprised of other fifth-year master of landscape architecture students with an underlying interest in art and design as place-making tools. Each student in the group addressed the site in Wichita, Kansas in a unique way. I addressed this site as a temporary landscape, creating an interactive light installation intended to be in place up to five years. In contrast, I addressed the Denver, Colorado site as a long term landscape, and designed a sculptural illuminating gateway. Each of these light art installations were informed by a particular set of characteristics that make each design site-specific.

This dissertation focuses on design sessions in which users and stakeholders participate. It demonstrates how material from field studies can be used in exploratory design sessions. The emphasis is on the staging and realization of experiments with ‘possible futures’. Using a design perspective I have worked with how field studies can contribute to design processes in which many parties collaborate. With a starting point in collaborative ‘sketching’ and creation of scenarios I have striven to create a meaningful way for design teams to adopt a practice perspective. The dissertation shows that there need not be any opposition between exploring ‘what is’ and envisioning ‘what can be’. The increase of computer technology in everyday life and the development making information technology become an integrated part of more and more everyday products has given rise to a need to find new ways of working in the process of designing. If it was ever possible to work in an isolated way on either digital or physical technology, this is no longer the case since development requires collaboration over these borders. In the same way, IT plays an increasing significant role in people’s everyday lives. User focus and user involvement have become commonplace. This calls for new ways of organizing the design process. The present dissertation meets this problem. I have participated in four projects in which exploring users everyday practices has become a meaningful design activity and a foundation for collaboration. The purpose of this dissertation is to shed light on the possibilities and the advantages offered by working design oriented with material from field studies. Furthermore, it strives to show how design sessions can be organized and carried out on a practical level and exemplifies with concrete projects. Special emphasis is given to the creation of and the inquiry into design material and the development and use of design games. / <p>In collaboration with School of Arts and Communication, Malmö University, Sweden.</p>

Thesis (PhD)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Autonomy and informed consent are two interrelated concepts given much prominence in contemporary biomedical discourse. The word autonomy, from the Greek autos (self) and nomos (rule), originally referred to the self-governance of independent Hellenic states, but was extended to individuals during the time of the Enlightenment, most notably through the work of Immanuel Kant and John Stuart Mill. In healthcare, the autonomy model is grounded in the idea of the dignity of persons and the claim people have on each other to privacy, self-direction, the establishment of their own values and life plans based on information and reasoning, and the freedom to act on the results of their contemplation. Autonomy thus finds expression in the ethical and legal requirement of informed consent. Feminists and multiculturalists have however argued that since autonomy rests on the Enlightenment ideals of rationality, objectivity and independence, unconstrained by emotional and spiritual qualities, it serves to isolate the individual and thus fails to rectify the dehumanisation and depersonalisation of modern scientific medical practice. It only serves to exacerbate the problematic power-differential between doctor and patient. Medicine is a unique profession since it operates in a space where religion, morality, metaphysics, science and culture come together. It is a privileged space because health care providers assume responsibility for the care of their patients outside the usual moral space defined by equality and autonomy. Patients necessarily relinquish some of their autonomy and power to experts and autonomy thus cannot account for the moral calling that epitomizes and defines medicine. Recognition of the dependence of patients need not be viewed negatively as a lack of autonomy or incompetence, but could rather reinforce the understanding of our shared human vulnerability and that we are all ultimately patients. There is however no need to abandon the concept of autonomy altogether. A world without autonomy is unconceivable. When we recognise how the concept functions in the modern world as a social construct, we can harness its positive properties to create a new form of identity. We can utilise the possibility of self-stylization embedded in autonomy to fashion ourselves into responsible moral agents that are responsive not only to ourselves, but also to others, whether in our own species or in that of another. Responsible agency depends on mature deliberators that are mindful of the necessary diversity of the moral life and the complex nature of the moral subject. I thus argue that the development of modern individualism should not be rejected altogether, since we cannot return to some pre-modern sense of community, or transcend it altogether in some postmodern deconstruction of the self. We also do not need to search for a different word to supplant the concept of autonomy in moral life. What we rather need is a different attitude of being in the world; an attitude that strives for holism, not only of the self, but also of the moral community. We can only be whole if we acknowledge and embrace our interdependence as social and moral beings, as Homo moralis. / AFRIKAANSE OPSOMMING: Outonomie en ingeligte toestemming is twee nou verwante konsepte wat beide prominensie in moderne bioetiese diskoers verwerf het. Die woord outonomie, van die Grieks autos (self) en nomos (reël), het oorspronklik verwys na die selfbestuur van onafhanklike Griekse state, maar is in die tyd van die Verligting uitgebrei om ook na individue te verwys, grotendeels deur die werk van Immanuel Kant en John Stuart Mill. In medisyne is die outonomie model gegrond op die idee van die waardigheid van die persoon en die beroep wat mense op mekaar het tot privaatheid, selfbepaling, die daarstelling van hulle eie waardesisteem en lewensplan, gebasseer op inligting en redenasie, en die vryheid om op die uitkoms van sulke redenasie te reageer. Outonomie word dus vergestalt in die etiese en wetlike bepaling van ingeligte toestemming. Feministe en multikulturele denkers beweer egter dat, siende outonomie gebasseer is op die Verligting ideale van rasionaliteit, objektiwiteit en onafhanklikheid, sonder die nodige begrensing deur emosionele en spirituele kwaliteite, dit die individu noodsaaklik isoleer en dus nie die dehumanisering en depersonalisering van moderne wetenskaplike mediese praktyk teenwerk nie. As sulks, vererger dit dus die problematiese magsverskil tussen die dokter en pasiënt. Die beroep van medisyne is ‘n unieke professie aangesien dit werksaam is in die sfeer waar geloof, moraliteit, metafisika, wetenskap en kultuur bymekaar kom. Dit is ‘n bevoorregde spasie aangesien gesondheidswerkers verantwoordelikheid vir die sorg van hulle pasiënte aanvaar buite die gewone morele spasie wat deur gelykheid en outonomie gedefinieer word. Pasiënte moet noodgedwonge van hulle outonomie en mag aan deskundiges afstaan en outonomie kan dus nie genoegsaam die morele roeping wat medisyne saamvat en definieer, vasvang nie. Bewustheid van die afhanklikheid van pasiënte hoef egter nie in ‘n negatiewe lig, as gebrek aan outonomie of onbevoegtheid, beskou te word nie, maar moet eerder die begrip van ons gedeelde menslike kwesbaarheid en die wete dat ons almal uiteindelik pasiënte is, versterk. Dit is verder nie nodig om die konsep van outonomie heeltemal te verwerp nie. ‘n Wêreld sonder outonomie is ondenkbaar. Wanneer ons bewus word van hoe die konsep in die moderne wêreld as ‘n sosiale konstruk funksioneer, kan ons die positiewe aspekte daarvan inspan om ‘n nuwe identiteit te bewerkstellig. Ons kan die moontlikheid van self-stilering, ingesluit in outonomie, gebruik om onsself in verantwoordelike morele agente te omskep sodat ons nie slegs teenoor onsself verantwoordelik is nie, maar ook teenoor ander, hetsy in ons eie spesie of in ‘n ander. Verantwoordelike agentskap is afhanklik van volwasse denkers wat gedagtig is aan die noodsaaklike diversiteit van die morele lewe en die komplekse aard van die morele subjek. Ek voer dus aan dat die ontwikkeling van moderne individualisme nie volstrek verwerp moet word nie, siende dat ons nie na ‘n tipe premoderne vorm van gemeenskap kan terugkeer, of dit oortref deur ‘n postmoderne dekonstruksie van die self nie. Ons het verder ook nie ‘n nuwe woord nodig om die konsep van outonomie in die morele lewe mee te vervang nie. Ons het eerder ‘n ander instelling van ons menswees in die wêreld nodig; ‘n instelling wat streef na volkomendheid, nie net van onsself nie, maar ook van die morele gemeenskap. Ons kan slegs volkome wees wanneer ons ons interafhanklikheid as sosiale en morele entiteite, as Homo moralis, erken en aangryp.

Abstract The act of knowing is a critical determinant of what is known, yet there are limits and potential violence inherent in all ways of knowing. Social workers have an ethical responsibility to understand our means of knowing and our knowledge claims – both shape the work we do. Conspicuously under-represented as creators of/commentators on how they are represented, people with intellectual disabilities have had little/no control over what or how they are known. These ethical and epistemological concerns were the focus of this arts-informed qualitative study. The purpose was an interrogative encounter with one way of knowing – how public photographic imagery of people with intellectual disabilities influences knowledge about them. It was concerned, however, to come to this knowledge through an inquiry into how labelled people would, themselves, interpret and respond to these representations, and how they might use photography to trouble disabling images and non-disabled (social work) knowing. Theoretically framed by a critical disability lens, the work was influenced, too, by Derrida’s essay on photography, “The Right of Inspection”. The other regarding aspect of the philosophy of Emmanuel Levinas, his concern with our ethical responsibility to the alterity of the Other, most powerfully informs the work. Four adults with intellectual disabilities accepted the invitation to participate in this project. First, they critically engaged with a selection of public photographic images. In a unique methodological turn, they then transformed the images to reflect their critique. Interpretive analysis of the critiques and transformations identified four thematic ideas. Participants’ critiques were insightful and profound; transformations provocative and disruptive. Challenging dominant assumptions – and demanding non-disabled others re-think intellectual disability and people so labeled – the critiques and transformations also respond to the social/political/ideological/psychological ramifications of photographic imagery on the lived experience of intellectual disability. Through the work, participants confront non-disabled responses to public photographs and to labeled people, challenging non-disabled others to question their knowledge, attitudes, and behaviours. The work also raises questions about research and people with intellectual disabilities: the possibilities for voice and empowerment through inclusive research strategies and visual methodologies, and the transformative potential of dialogic encounters between people with and without intellectual disabilities.
