Gavin Turk
No full textPart of the YBA (Young British Artist) movement of the mid-1990s, Gavin Turk has created pioneering works of contemporary art using materials such as painted bronze, wax, and garbage. His installations, sculptures, and images refer to issues of authorship, authenticity, and identity and toy with the art historical establishment. Featuring numerous color illustrations, the volume includes Turk's major works since the early 1990s as well as three texts. One of these, an original essay by Iain Sinclair, contextualizes the artist's work under the umbrella of psycho-geography, including the impact of London on Turk's persona
Comment on "Measurement of quantum states of neutrons in the Earth's gravitational field"
No full textIn the paper by Nesvizhevsky et al. [Phys. Rev. D 67, 102002 (2003)], it is argued that the lowest quantum state of neutrons in the Earth's gravitational field has been experimentally identified. While this is most likely correct, it is imperative to investigate all alternative explanations of the result in order to close all loopholes, as it is the first experiment ever claimed to have observed gravitational quantum states. Here we show that geometrical effects in the experimental setup can mimic the results attributed to gravity. Modifications of the experimental setup to close these possible loopholes are suggested

ENHANCING IMAGE FINDABILITY THROUGH A DUAL-PERSPECTIVE NAVIGATION FRAMEWORK
No full textThis dissertation focuses on investigating whether users will locate desired images more efficiently and effectively when they are provided with information descriptors from both experts and the general public. This study develops a way to support image finding through a human-computer interface by providing subject headings and social tags about the image collection and preserving the information scent (Pirolli, 2007) during the image search experience.
In order to improve search performance most proposed solutions integrating experts’ annotations and social tags focus on how to utilize controlled vocabularies to structure folksonomies which are taxonomies created by multiple users (Peters, 2009). However, these solutions merely map terms from one domain into the other without considering the inherent differences between the two. In addition, many websites reflect the benefits of using both descriptors by applying a multiple interface approach (McGrenere, Baecker, & Booth, 2002), but this type of navigational support only allows users to access one information source at a time. By contrast, this study is to develop an approach to integrate these two features to facilitate finding resources without changing their nature or forcing users to choose one means or the other.
Driven by the concept of information scent, the main contribution of this dissertation is to conduct an experiment to explore whether the images can be found more efficiently and effectively when multiple access routes with two information descriptors are provided to users in the dual-perspective navigation framework. This framework has proven to be more effective and efficient than the subject heading-only and tag-only interfaces for exploratory tasks in this study. This finding can assist interface designers who struggle with determining what information is best to help users and facilitate the searching tasks. Although this study explicitly focuses on image search, the result may be applicable to wide variety of other domains. The lack of textual content in image systems makes them particularly hard to locate using traditional search methods. While the role of professionals in describing items in a collection of images, the role of the crowd in assigning social tags augments this professional effort in a cost effective manner
Neuromechanical measurement of motor impairments in relation to upper limb activity limitations after stroke
No full textLoss of upper-limb function is a problem following stroke. Recent research has led to the emergence of new treatments but progress is hampered by lack of reliable objective measures of impairment, and understanding of the underlying impairment mechanisms associated with loss and recovery of functional activity. The aim of this research was to identify, using neuromechanical measurement methods, inter-relationships between motor impairments, and correlates of motor impairments with functional activity limitation in the upper limb of acute and chronic stroke survivors.An instrumented rig has been developed to measure impairments: muscle weakness, active range of movement, motor control accuracy in rhythmic and discrete tracking tasks, spasticity, coactivation, contracture and non-neural stiffness. In pilot studies, signal processing and data analysis techniques have been used to generate novel, clinically and physiologically relevant indices to quantify impairments. In a Main Study, 13 older impaired participants in the acute phase post-stroke, 13 in the chronic phase 14 age-matched unimpaired participants underwent rig assessments and performed a test of upper limb activity. A sub-group of impaired participants were tested on two days for test-retest reliability evaluation.Statistical tests have confirmed the validity of the impairments to distinguish between acute and chronic patients and unimpaired individuals, except coactivation during discrete movements and non-neural stiffness. Repeatability coefficients for the active test indices have been presented as benchmark values for use in future trials. The muscle activation indices showed lower repeatability which highlights the challenge of using these to measure change over time. The impairments that contributed to lower motor control accuracy were reduced extensor weakness, delayed extensor onset timing, coactivation and smaller extension AROM and PROM; coactivation was more strongly associated with motor control accuracy than with spasticity or stiffness.The most important contributors to functional activity in the acute group was extensor weakness, and in the chronic group was motor control accuracy and coactivation (rhythmic task). Contracture was important contributor in both groups, and was associated with weakness and loss of active range of movement rather than spasticity. The findings support the notion that rehabilitation strategies should focus on increasing muscle strength and prevention of contracture. However, assessment of more complex impairments like motor control accuracy and coactivation may be crucial to better target therapy, especially in the later phases post-stroke
Trade unions in Turkey : an analysis of their development, role and present situation
No full textThis thesis focuses on the trade union movement in Turkey with particular reference to the Turkish
confederation of trade unions (TURK-IS) and its members. Case studies were conducted in both TURKIS
and its member unions, widely, based on open-ended interviews with union officials, but also
involving the analysis of union's reports, documents and journals, the observation of workers education
seminars and visits to the state's institutions and employers' organisations. The main purposes of the
thesis have been to illustrate the changing nature, role and struggle of the Turkish unions in the context
of the changing economic, political and social structure of Turkey. It also focuses on the dominant
trends in trade unionism in a European context.
The study argues that an explicit and theorised understanding of internal and external pressure on the
trade union movements as they emerge in many countries, is of fundamental significance to the Turkish
trade unions. It is argued that the trend in the Turkish labour relations in the 1960s and 70s seemed to
be the co-operation of unions in the formulation of policies, related to national economic performance
and social stability in politics. In other words, unions were tolerated to provide both economic and
social stability at macro level and manageability and certainty at micro level in the light of the
industrialisation process.
In this context, Import Substitution Industrialisation (lSI) was the model of capital accumulation, which
required trade unions to become integrated within the new economic and political policies in order to
secure an economically and politically stable industrial relations framework. In this respect, the Turkish
unions played a mediating role between the state, employers and workers.
It is also argued that the changing system of capital accumulation (a move from lSI to "market
liberalism") in the 1980s has endangered the traditional institutional arrangements. The traditional role
of interest representation for unions, particularly as mediation between the ruling class and working
class, has become problematic. The decline of union power, due to changes in their environments, has
also weakened the value of central labour organisations as mediators between the state, employers and
workers. The anti-labour policies seems to have been the outcome of strategic interventions of the
governments and employers. In this context, particularly in the 1980s explicit reference to theoretical
frameworks have tended to increase in favour of "strategic choices" and "union identities".
The study argues that in the Turkish case, unions have not been faced with a complete policy of
exclusion. In other words, the material conditions of "integrative" "collaborative" or "corporatist"
policies have been reduced, however, they have not been completely eliminated. The reasons for this
might be that although the economic power of TURK-IS and its members was no longer so important
for the government, the political mediating role of unions became significant in the period of the 1980s,
which included the transition to democracy, the process of integration of Europe, the implementation of
austerity policies and the fear of the possible failure of the parliamentary regime.
I argue in the thesis that under the painful and complex process of economic and political
reconstruction and the development of democracy the Turkish trade unions have been faced with a
number of tactical and political options in the rapidly evolving the issue of European Integration and of
democracy and the increasing uniformity amongst member of TURK-IS. The Turkish case suggests that
trade unions can achieve a position of influence in industrial relations systems as long as they pursue
politically motivated strategies by setting a new agenda for members, articulating the broad long-term
interests of the working class and finally displaying collective responses and collective responsibility. In
this respect, it is argued that there is still a significant scope for a more active initiating and coordinating
role for central labour organisations and unions can pursue more comprehensive and tenable
trade union strategies
