A web-based system for visualizing upper limb motor performance of Parkinson’s disease patients

Objective To design, develop and set up a web-based system for enabling graphical visualization of upper limb motor performance (ULMP) of Parkinson’s disease (PD) patients to clinicians. Background Sixty-five patients diagnosed with advanced PD have used a test battery, implemented in a touch-screen handheld computer, in their home environment settings over the course of a 3-year clinical study. The test items consisted of objective measures of ULMP through a set of upper limb motor tests (finger to tapping and spiral drawings). For the tapping tests, patients were asked to perform alternate tapping of two buttons as fast and accurate as possible, first using the right hand and then the left hand. The test duration was 20 seconds. For the spiral drawing test, patients traced a pre-drawn Archimedes spiral using the dominant hand, and the test was repeated 3 times per test occasion. In total, the study database consisted of symptom assessments during 10079 test occasions. Methods Visualization of ULMP The web-based system is used by two neurologists for assessing the performance of PD patients during motor tests collected over the course of the said study. The system employs animations, scatter plots and time series graphs to visualize the ULMP of patients to the neurologists. The performance during spiral tests is depicted by animating the three spiral drawings, allowing the neurologists to observe real-time accelerations or hesitations and sharp changes during the actual drawing process. The tapping performance is visualized by displaying different types of graphs. Information presented included distribution of taps over the two buttons, horizontal tap distance vs. time, vertical tap distance vs. time, and tapping reaction time over the test length. Assessments Different scales are utilized by the neurologists to assess the observed impairments. For the spiral drawing performance, the neurologists rated firstly the ‘impairment’ using a 0 (no impairment) – 10 (extremely severe) scale, secondly three kinematic properties: ‘drawing speed’, ‘irregularity’ and ‘hesitation’ using a 0 (normal) – 4 (extremely severe) scale, and thirdly the probable ‘cause’ for the said impairment using 3 choices including Tremor, Bradykinesia/Rigidity and Dyskinesia. For the tapping performance, a 0 (normal) – 4 (extremely severe) scale is used for first rating four tapping properties: ‘tapping speed’, ‘accuracy’, ‘fatigue’, ‘arrhythmia’, and then the ‘global tapping severity’ (GTS). To achieve a common basis for assessment, initially one neurologist (DN) performed preliminary ratings by browsing through the database to collect and rate at least 20 samples of each GTS level and at least 33 samples of each ‘cause’ category. These preliminary ratings were then observed by the two neurologists (DN and PG) to be used as templates for rating of tests afterwards. In another track, the system randomly selected one test occasion per patient and visualized its items, that is tapping and spiral drawings, to the two neurologists. Statistical methods Inter-rater agreements were assessed using weighted Kappa coefficient. The internal consistency of properties of tapping and spiral drawing tests were assessed using Cronbach’s α test. One-way ANOVA test followed by Tukey multiple comparisons test was used to test if mean scores of properties of tapping and spiral drawing tests were different among GTS and ‘cause’ categories, respectively. Results When rating tapping graphs, inter-rater agreements (Kappa) were as follows: GTS (0.61), ‘tapping speed’ (0.89), ‘accuracy’ (0.66), ‘fatigue’ (0.57) and ‘arrhythmia’ (0.33). The poor inter-rater agreement when assessing “arrhythmia” may be as a result of observation of different things in the graphs, among the two raters. When rating animated spirals, both raters had very good agreement when assessing severity of spiral drawings, that is, ‘impairment’ (0.85) and irregularity (0.72). However, there were poor agreements between the two raters when assessing ‘cause’ (0.38) and time-information properties like ‘drawing speed’ (0.25) and ‘hesitation’ (0.21). Tapping properties, that is ‘tapping speed’, ‘accuracy’, ‘fatigue’ and ‘arrhythmia’ had satisfactory internal consistency with a Cronbach’s α coefficient of 0.77. In general, the trends of mean scores of tapping properties worsened with increasing levels of GTS. The mean scores of the four properties were significantly different to each other, only at different levels. In contrast from tapping properties, kinematic properties of spirals, that is ‘drawing speed’, ‘irregularity’ and ‘hesitation’ had a questionable consistency among them with a coefficient of 0.66. Bradykinetic spirals were associated with more impaired speed (mean = 83.7 % worse, P < 0.001) and hesitation (mean = 77.8% worse, P < 0.001), compared to dyskinetic spirals. Both these ‘cause’ categories had similar mean scores of ‘impairment’ and ‘irregularity’. Conclusions In contrast from current approaches used in clinical setting for the assessment of PD symptoms, this system enables clinicians to animate easily and realistically the ULMP of patients who at the same time are at their homes. Dynamic access of visualized motor tests may also be useful when observing and evaluating therapy-related complications such as under- and over-medications. In future, we foresee to utilize these manual ratings for developing and validating computer methods for automating the process of assessing ULMP of PD patients.

An analysis of Samoan reaction to The Orator (O Le Tulafale)’s Fāgogo defining Samoan identity

The Orator (O Le Tulafale) was promoted as the first Samoan language film shot in Samoa with a Samoan cast and crew. Written and directed by Samoan filmmaker Tusi Tamasese, the film succeeded at several of the movie industry’s prestigious festivals. The Orator (O Le Tulafale) is about an outcast family of a dwarf (Saili), his wife and her teenage daughter. As the main protagonist, Saili battles to overcome his fears to become a chief to save his family and land. The film’s themes are courage, love, honour , as well as hypocrisy, violence, and discrimination. A backlash by Samoans was predicted ; however, the opposite occurred. This raised the following questions: first, what is it about the film causing this reaction? It is a 106 -minute film shot in Samoa about Samoans and the Samoan culture . D espite promotional claims about the film , there have been Samoan -produced films in Samoa . Secondly, to what are Samoans really responding? Is it 1) just to the film because it is about Samoa, or 2) are they responding to themselves , and how they reacted during the act of watching the film? This implies levels of reactions in the act of watching, and examining the dominant level of response is important. To explore this, t he Samoan story telling technique of Fāgogo was used to analyse the film’s narration and narrative techniques. R. Allen’s (1993, 1997) concept of projected illusion was employed to discuss the relationship between Samoans and the film developed during the act of watching. An examination of the term Samoan and a description of the framework of Fa’a Samoa (Samoan culture) were provided. Also included were discussions of memory and its impact on Samoan cultural identity. The analysis indicated that The Orator (O Le Tulafale) acted as a memory prompt through which Samoans recalled memories confirming and defining cultural bonds. These memories constituted the essence of being Samoan. These memories were awakened, and shared as oral histories as fāgogo. The receivers appeared to interpret the shared memories to create their own memories and stories to suit their contexts, according to Facebook postings. An interpretation is that the organic sharing of memories as fā gogo created a global definition of Samoan that Samoans internationally claimed.

Kommunal marknadsföring- Competitive identity och institutionell problematik : En komparativ fallstudie om två svenska kommuner och deras marknadsföring

Historiskt sett finns det etablerade normer i samhället som säger att en kommun endast ska bedriva traditionell kommunal verksamhet som innefattar att tillgodose välfärden (vård, skola & omsorg). Dock så har globaliseringen och urbaniseringen skapat en konkurrens om invånare vilket har lett till att kommuner idag bedriver en allt mer utvecklad marknadsföring för att attrahera fler invånare. Den här fallstudien innehåller två objekt (kommuner). Vi vill undersöka den kommunala marknadsföringen genom att fokusera på begreppen competitive identity (CI) och institutionell problematik (IP). Begreppet CI innehåller en teoretisk genomgång av komponenter i kommunal marknadsföring och IP beskriver kommunernas komplexa situation med olika institutionella krav. Genom att analysera dessa begrepp mot praktiska fall kan vi bidra till ökad förståelse om kommunal marknadsföring som är vårt syfte. Vi presenterar även en egen modell i samband med begreppet CI som ger en nyanserad bild av ämnet. Studiens resultat identifierar att kommunerna har speciella målgrupper som likt ett företag varierar beroende på deras ställning på marknaden. Genom skapandet av en CI deklarerar kommunen en önskvärd image där företeelser som inte bidrar till den blir exkluderade. Det gestaltar sig på olika sätt vilket analyseras grundligt i studien. Samtidigt illustreras motsägelsen när respondenterna i fallen säger att det är medborgarna som håller uppe imagen. Studien visar att det inte finns en enhetlig bild hur man som kommun ska hantera den institutionella komplexitet som uppstår. Fallen presenterar två olika synsätt som de finner mer lämpligt.

Identity and image – the story of expertise in a manufacturing company

This thesis is an investigation on the corporate identity of the firm SSAB from a managerial viewpoint (1), the company communication through press releases (2), and the image of the company as portrayed in news press articles (3). The managerial view of the corporate identity is researched through interviews with a communication manager of SSAB (1), the corporate communication is researched through press releases from the company (2) and the image is researched in news press articles (3). The results have been deducted using content analysis. The three dimensions are compared in order to see if the topics are coherent. This work builds on earlier research in corporate identity and image research, stakeholder theory, corporate communication and media reputation theory. This is interesting to research as the image of the company framed by the media affects, among other things, the possibility for the company to attract new talent and employees. If there are different stories, or topics, told in the three dimensions then the future employees may not share the view of the company with the managers in it. The analysis show that there is a discrepancy between the topics on the three dimensions, both between the corporate identity and the communication through press releases, as well as between the communication through press releases and the image in news press articles.

The rhetorics of violence in Joshua: Foucauldian Power, Israelite Identity, and the Ethics of Interpretation

The goals of this project are manifold. First, I will attempt to discover evidence in the book of Joshua that will lend support to the theory of a Josianic influence enacted in the 7th century BCE. I will do this through an analysis of the rhetoric in selected stories in Joshua using the ideas of Foucault. Second, I will address the significance of this kind of analysis as having potential for the emancipation of oppressed peoples. The first section delineates scholarly discussion on the literary and historical context of the book of Joshua. These scholarly works are foundational to this study because they situate the text within a particular period in history and within certain ideologies. Chapter 2 discusses the work of Foucault and how his ideas will be applied to particular texts of the book of Joshua. The focused analysis of these texts occurs within chapters 3 to 6. Chapter 7 presents an integration of the observations made through the analyses performed in the previous chapters and expands on the ethical significance of this study.

Stranger in a Strange Land: The struggle for cultural and personal identity in Haruki Murakami's Hard-Boiled Wonderland and the End of the World

In order to explicate Murakami's version of the official culture, I have analyzed the novel with the works of several different theorists. Primarily, I drew my own understanding of the official culture from Raymond Williams's examination of culture in Marxism and Literature. His terminology became helpful in writing about the operation of the System and the Town, though it did not define that operation precisely. Williams's work also introduced me to the theory behind the official culture's manipulation and exclusion of historical aspects in order to create their "official" version of history, from which the official culture draws its identity. For further analysis of the treatment of history, I turned to Friedrich Nietzsche's On the Advantage and Disadvantage of History for Life. Though it examines the official culture's manipulation of history in a much more in-depth manner, it seems to have influenced Murakami's treatment of individual memories and cultural histories. For instance, the herd ofunicoms in the End of the World resembles Nietzsche's description of the ''unhistorical herd," or has the potential to resemble it. With these theories I was able to access the mechanisms of cultural control that Murakami depicts in the form of the System and the Town, and from there I was able to develop a model for how the narrator struggles to subvert that control. Both sides of that struggle are depicted and re-imagined many times throughout Hard-Boiled Wonderland and the End of the World.

Dwelling in possibility: aestheticizing identity in African American women's fiction

African American women writers define aesthetics through their negotiation of identity in the politicized loci of space, place and voice. In the balkanization of such issues of voice and space, we can see the ways that the emergent selfis embodied and aestheticized in literature. To do so creates a more tactile and "artfull" representation of the self rather than a representation of identity as a mere abstract concept. To use written language to express the self is to carry processes of selfdefinition for black women into the realm of creative production. For women, especially black women, who are a politically and socially compromised element of society, the written word is a way of expressing the politically and the socially critical voice that is suppressed in other forums of expression. Using theories on "writing in difference" as a skeleton key, this project seeks to outline some of the ways that black women writers use aesthetic elements in their art to express the potential for self-examination, discovery, and emancipation.
