Lidande är en naturlig och oundviklig del av det mänskliga livet. En av de mest centrala uppgifterna inom vården innebär att lindra lidande. Därmed är det aktuellt att undersöka områdets kunskapsposition. Syftet var att beskriva lidande i omvårdnadStudien genomfördes som en litteraturstudie där 15 vetenskapliga artiklar utgjorde underlaget för resultatet. Resultatet i denna studie delades in i sex tema inom omvårdnad: ”Existentiellt lidande”, ”Livslidande”, ”Sjukdomslidande”, ”Vårdlidande”, ”Den vårdande personalens upplevelser av lidande” och ”Socioemotionellt lidande”. Studien visar att forskning i nutid på många sätt beskriver uttryck för patientens lidande i liknande former som det lidande som beskrivits i forskning tidigare. Utöver detta framkommer även beskrivningar av lindrande av lidande inom omvårdnad. Det framkommer att fokus i vården tenderar att ligga främst på att behandla fysiska symptom. En helhetssyn, där även existentiella, psykologiska, kulturella och sociala dimensioner uppmärksammas, är nödvändig för att förbättra patientens hälsa och minska patientens lidande.För att kunna möta patienten i lidandet krävs medvetenhet hos sjuksköterskan kring egna upplevelser av lidande. Fortsatt forskning samt belysning av området i sjuksköterskeprogrammet är betydelsefullt. / Suffering is a natural and inevitable part of human life. One of the central parts in health care is to alleviate suffering. Consequently, the present knowledge state is of importance to follow up. The aim of this study was to describe suffering in nursing. The study was conducted as a literature review were 15 scientific articles were the basis for the results. The result of this literaturereview was divided into six themes in nursing: "Existential suffering", "Suffering in life", “Suffering in illness", "Suffering in care", "Socioemotional suffering" and ”Perceptions of suffering in nursing staff." Expressions of suffering of the patient are found to be found similar in recent studies compared to the suffering described in research further back. Recent studies additionally indicate other expressions of suffering and approaches to alleviate suffering in nursing. It emerges that the focus in care tends to be primarily focused on treatment of physical symptoms. A holistic focus, with awareness of existential, psychological, cultural and social dimensions, is necessary to promote health and to alleviate suffering. To respond to the patient in its suffering, awareness of the nurse’s own experiences of suffering is required. Further research and illumination of the subject in the nursing program is of importance.

Hungarian 'focus position' is typically thought of as a central example of a 'discourse configurational' phenomenon, since it not only involves the expression of information-structural (or 'discourse semantic') meaning through the manipulation of word order but also interacts syntactically with other elements of the sentence. In this thesis, I argue that this kind of phenomenon highlights fundamental theoretical problems with conventional assumptions about the relationships between linguistic form and different kinds of meaning and demonstrate that these problems have led to empirical inadequacies in the syntactic analysis of Hungarian. I propose an alternative analysis that makes use of a dynamic, incremental parsing-based approach to grammar, which in turn allows for the influence of inferential pragmatic operations (investigated in terms of Relevance Theory) at all stages in the process of interpreting linguistic form. This opens up possibilities of structural and interpretive underspecification that allow for the interpretation of the 'focus position' to be unified with the information-structural interpretation of sentences that do not contain a syntactically focused expression. This analysis explains the interaction of syntactic foci with other pre-verbal items. The burden of explanation is thus shifted away from specialised, abstract syntactic representations and onto independently necessary aspects of cognitive organisation. The use of 'discourse semantic' primitives---whether in terms of focus or exhaustivity---to encode the effects of the 'focus position' is shown to be both theoretically problematic and empirically inadequate. The information-structural meanings associated with the position must be viewed not as the input to interpretive processes but instead as the result of inferential processes performed in context. Reanalysis of the syntactic evidence shows the relevant position to be not merely pre-verbal, but underlyingly pre-tense, showing that the unmarked position of the main verb is essentially the same as that of syntactically focused expressions. This leads to an analysis whereby both 'neutral', topic-comment readings and cases of narrow focus emerge from inferences over a common interpretive procedure. This procedure is identified as 'main predication': the point in the parsing of a sentence at which the application of a single predicate effects the conversion of a mere description of an event into a truth-conditional assertion. Main predication is represented using neo-Davidsonian, event-based semantics (the effect of the main predicate being equivalent to that of the application of an existential quantifier over an event variable in the neo-Davidsonian approach) and made dynamic by the use of the epsilon calculus. This analysis predicts the postposing of any (otherwise pre-tense) 'verbal modifier' (VM) in the presence of a syntactic focus and the apparent information-structural ambiguity of VMs when they are pre-tense. Certain constraints on the distribution of quantifiers are also predicted, one such constraint being adequately characterisable only within a semantically underspecified, procedural account. The behaviour of the negative particle "nem" is also given a maximally simple explanation. The apparently variable scope of the negative operator is explicable without ad hoc syntactic mechanisms: the apparent wide scope reading associated with 'sentential' negation follows inferentially from narrow scope negation of temporal information. The syntactic positions of negation are predictable on this basis. In addition, the assumption of consistent narrow scope negation correctly predicts that VMs must postpose or receive a narrow focus reading in the presence of "nem".

In recent years, technical advances in the field of Augmented Reality (AR), coupled with the acceleration in computer and graphics processing power, have brought robust and affordable AR within the reach of the wider research community. While the technical issues of AR remain heavily researched, there is also a growing amount of work on user interface development and evaluation, heralding the convergence of traditional Human Computer Interaction (HCI) and AR. Magic Lenses are 2D interface components that provide alternative representations of objects seen through them. In this way, they can be used to provide Focus and Context in the interface, especially when visualising layered information. There are very few, if any, formal evaluations to guide the development of lens-based interfaces. This thesis describes the development and evaluation of Magic Lenses as a tool for AR interfaces. The work starts with a comprehensive survey of many Focus and Context techniques, which are classified based on the way they present views to the users { for example, a Magic Lens is a spatially separated multiple view technique. A formal evaluation of 2D Magic Lenses in a GIS scenario found that users strongly preferred the lens-based interaction technique to others, largely because it reduced the effort of interaction. Accuracy was high with the lenses, but a simple "global view" interface allowed significantly faster performance. This positive result motivated further work on Magic Lenses within AR, where the lens metaphor can reinforce the tangible interaction methods that link virtual and real content. To support rapid exploration of interaction alternatives with AR Magic Lenses, I describe the design and architecture of osgART, an AR development toolkit that is available to the research community as open-source software. Object selection and manipulation is a fundamental interaction requirement for all AR interfaces, and I establish an empirical foundation of performance in this task with a variety of AR interaction techniques, including Magic Lenses. Results show that performance with all techniques is successfully modelled by Fitt's Law, and that Magic Lenses outperformed other techniques. Finally, I examine new interaction techniques based on Magic Lenses, particularly a Flexible Sheet Lens, which allows concurrent bimanual specification of multiple parameters within the visualisation.

Four focus groups were conducted in Kentucky to evaluate differences in the participants knowledge of safe food handling practices, where they obtained their knowledge, which source(s) they trusted to provide accurate food safety messages and the effectiveness of messages from three different sources. The sources of food safety messages compared by the focus groups were the Partnership for Food Safety Educations FightBAC! material, food safety materials developed by the American Dietetic Association and funded by ConAgra Foundation and food safety materials developed by the University of Kentucky. Each focus group represented a specific population, (A) limited resource parents (Louisville); (B) married males (Lexington); (C) mothers of young children (Danville); and, (D) females of varied age with background of Cooperative Extension Service sponsored consumer education in food preparation (Lexington). Follow up interviews were conducted through a telephone survey to inquire as to whether any food safety practices had been implemented since participation in the focus groups. The results of the interview revealed that participants expressed varying familiarity with safe food handling practices, varying understanding of the food safety messages and diverse acceptance and preference for the delivery mechanisms.

The purpose of this study was to investigate elite soccer players' attentional focus during their best performances, better understand the strategies they use to enter or re-enter optimal attentional states, and explore potential attentional differences according to soccer positions, performance tasks, and game situations. No previous studies have explored elite soccer players' attentional skills from a naturalistic and qualitative perspective in such detail. The growing interest in soccer among Canadians provided further justification for this study. Data collection consisted of individual semi-structured interviews with eight elite soccer players from five main soccer positions, namely goalkeeper, defender, wing, midfielder, and forward. Cross-case thematic analysis indicated positive thinking and pre-performance routines as important sources of optimal focus. Attentional focus varied according to soccer positions and performance tasks. Information processing, sport expertise, and attentional systems theoretical frameworks informed the discussion of results. Applied and theoretical implications were drawn and future studies were recommended.

Impaired performance while executing a motor task is attributed to a disruption of normal automatic processes when an internal focus of attention is used (Wulf, McNevin, & Shea, 2001). When an external focus of attention is adopted, automaticity is not constrained and improved performance is noted. What remains unclear is whether the specificity of internally focused task instructions may impact task performance. In the present study, behavioural, kinematic and neurophysiological outcome measures assessed the implications of changing attentional focus for novice and skilled performers in a golf putting task. Findings provided evidence that when novice participants used an internal focus of attention related to task execution, accuracy, kinematics of the putter, and variability of EMG activity in the upper extremity were all adversely affected as task difficulty increased. Instructions which were internal but anatomically distal to the primary movement during the task appeared to have an effect similar to an external focus of attention and did not adversely affect outcomes.

Temporal perspective is a multi-dimensional term for how individuals focus attention toward the past, present, and future. There have been few investigations into the relationship between temporal perspective and well-being. Temporal perspective has predominantly been measured with single-occasion measurement designs, which ignore the potential for within-person variations that may be important in accounting for fluctuations in well-being. The current study examined the dimensions of temporal perspective (temporal focus, temporal attitude, and temporal distance) and their dynamic relationships with well-being. A 14-day daily diary design was employed to examine whether people fluctuate in their temporal perspective, and if these fluctuations systematically covary with daily well-being. The results from multilevel analyses supported the following conclusions: (a) there is evidence of within-person variability in daily temporal perspective, and (b) this within-person variability in temporal perspective fluctuates systematically with fluctuations in daily well-being. Each temporal perspective dimension was useful in predicting daily well-being. / Graduate / 0621

Since the Web is getting bigger and bigger with a rapidly increasing number of heterogeneous Web pages, Web users often suffer from two problems: P1) irrelevant information and P2) information overload Irrelevant information indicates the weak relevance between the retrieved information and a user's information need. Information overload indicates that the retrieved information may contain 1) redundant information (e.g., common information between two retrieved Web pages) or 2) too much amount of information which cannot be easily understood by a user. We consider four major causes of those two problems P1) and P2) as follows; ??? Firstly, ambiguous query-terms. ??? Secondly, ambiguous terms in a Web page. ??? Thirdly, a query and a Web page cannot be semantically matched, because of the first and second causes. ??? Fourthly, the whole content of a Web page is a coarse context-boundary to measure the similarity between the Web page and a query. To answer those two problems P1) and P2), we consider that the meanings of words in a Web page and a query are primitive hints for understanding the related semantics of the Web page. Thus, in this dissertation, we developed three cooperative technologies: Word Sense Based Web Information Retrieval (WSBWIR), Subjective Segment Importance Model (SSIM) and Topic Focused Web Page Summarization (TFWPS). ??? WSBWIR allows for a user to 1) describe their information needs at senselevel and 2) provides one way for users to conceptually explore information existing within Web pages. ??? SSIM discovers a semantic structure of a Web page. A semantic structure respects not only Web page authors logical presentation structures but also a user specific topic interests on the Web pages at query time. ??? TFWPS dynamically generates extractive summaries respecting a user's topic interests. WSBWIR, SSIM and TFWPS technologies are implemented and experimented through several case-studies, classification and clustering tasks. Our experiments demonstrated that 1) the comparable effectiveness of exploration of Web pages using word senses, and 2) the segments partitioned by SSIM and summaries generated by TFWPS can provide more topically coherent features for classification and clustering purposes.

In the form of a potable spirit, an extract of grapefruit skin has been found to develop an attractive opalescence when diluted to below about 38 % ethanol (v/v). This phenomenon is analogous to the pastis effect, called louching, common in many drinks popular in some countries bordering the Mediterranean. The main objective of this research was to develop spirit liquor with commercial potential from grapefruit skin, largely a waste commercial product, as the dominant if not exclusive ingredient other than alcohol and water. This would require making extracts by distillation of undried skins, which would develop a dense opalescence significantly below 40 % v/v ethanol, the common alcoholic strength of spirits as sold in New Zealand. The product concept was thus a clear liquid which when poured over ice for example, would yield a cool opalescent drink with a characteristic grapefruit flavour. In the case of citrus, the chemical basis of louching is the greater solubility of citrus skin terpenes, principally limonene, in ethanol than in water. The louch point is synonymous with the chemical expression critical micelle concentration, detected here by light scattering at the arbitrary wavelength of 450 nm. Early results with an obvious opalescence showed that the alcohol concentration at which the terpenes ceased to be soluble in the grapefruit distillate was about 38 % (v/v). This point was similar to that for pastis (Pernod brand), where the principle louchable ingredient is anethole. However, the light scattering was much greater for pastis. Thus, a grapefruit spirit sold at 40 % ethanol with the louching intensity of pastis should require increasing the solubility of limonene in solutions with a lower ethanol concentration. This in turn should allow higher concentrations of limonene in true solution in 40 % ethanol, theoretically resulting in a more intense louch in the final drink. Thus, a broad range of hydrocolloids and surfactants was tested in an attempt to increase the solubility of limonene in lower ethanol concentrations. None of hydrocolloids or surfactants lowered the louch point of a standard limonene concentration in ethanol/water. The informal flavour assessment showed that the spirit flavour from grapefruit zest alone lacked intensity. It was then thought that better flavour might be obtained by using the whole grapefruit (zest, pith, and juice) rather than zest alone. The additional of pith or pith plus juice caused no significant change in the louch point or light scattering. However, the final flavour was informally judged to be more intense than that derived from zest alone. The problem still remained that the light scattering of grapefruit distillate was never as high as that achieved by pastis, even though it was found (by gas chromatography) that the concentration of limonene (w/w) in the grapefruit spirit was at least as high as that of anethole in pastis. The cause was due to the fact that as a louched compound, anethole was a solid with a flat crystal structure because the melting point (21.4C) is well above that of a cool drink (Handbook of Chemistry and Physics, 1947). By contrast, limonene remains a liquid even in an iced drink because its melting point is far below 0C. Flat crystals would obviously scatter light far more than would a micelle containing a liquid, in this case limonene. Although such a grapefruit distillate did not louch as well as pastis, it could still have market potential on the basis that it would be made from the distinctive New Zealand cultivar of grapefruit. Thus a formal sensory assessment was conducted, using a focus group. The grapefruit distillates at 40 % ethanol were perceived by most panellists as refreshing, clean, fruity, and citrusy in aroma, but somewhat deficient in grapefruit flavour, and there was a common perception of strong chemical finish. At this stage of development a commercial proposition cannot be sensibly made.
