No / Surface blending with tangential continuity is most widely applied in computer-aided design, manufacturing systems, and geometric modeling. In this paper, we propose a new blending method to effectively control the shape of blending surfaces, which can also satisfy the blending constraints of tangent continuity exactly. This new blending method is based on the concept of swept surfaces controlled by a vector-valued fourth order ordinary differential equation (ODE). It creates blending surfaces by sweeping a generator along two trimlines and making the generator exactly satisfy the tangential constraints at the trimlines. The shape of blending surfaces is controlled by manipulating the generator with the solution to a vector-valued fourth order ODE. This new blending methods have the following advantages: (1) exact satisfaction of C1C1 continuous blending boundary constraints, (2) effective shape control of blending surfaces, (3) high computing efficiency due to explicit mathematical representation of blending surfaces, and (4) ability to blend multiple (more than two) primary surfaces.

Yes / Objectives: Qualitative research has suggested that spousal experiences of discontinuity in their relationship with a person who has dementia (i.e. the relationship is experienced as radically changed) may contribute to heightened feelings of burden, entrapment, isolation, guilt and intolerance of behaviours that challenge. By contrast, continuity in the relationship may contribute to a greater sense of achievement and gratification from providing care. The present study served as a quantitative test of these suggestions. Method: A convenience sample of 71 spouses of people with dementia completed three questionnaires - the Zarit Burden Interview (ZBI), the Positive Aspects of Caregiving measure (PAC) and the Birmingham Relationship Continuity Measure (BRCM). Results: In accordance with the hypotheses, the experience of greater relationship continuity (higher BRCM scores) was correlated with fewer negative emotional reactions to caregiving (lower ZBI scores; rho = −.795) and more positive emotional reactions (higher PAC scores; rho = .764). Conclusions: The study provided some quantitative support for suggestions arising from qualitative research about how perceptions of continuity/discontinuity in the relationship may impact on the caregiving spouse's emotional well-being. Helping couples to maintain a sense of continuity and couplehood may assist their emotional adjustment to dementia.

No / Ex-offenders re-enter their communities with limited pre-release preparation for the continuity of access to health care once outside prison. Once released, these individuals become hard to reach, do not consider health a priority and consequently use services to address their health and social care needs in a crisis-led way. Nevertheless, how nurses can best support these health-excluded group of individuals in the community remains vague and requires discussion. It is argued that current dominant discourses around equity of care are contradicted in the provision of health and social care services to ex-offenders in the community. Effective engagement with community interventions may be achieved if ex-offenders maintain contact with frontline providers who can support both their structural and health needs. Nurses are uniquely positioned to initiate and sustain contact with ex-offenders, intervening at points of greatest need in the community to address the socially significant health and social care issues that plague them. The use of nurses in the provision of health and social care interventions to ex-offenders is a strategy, which could increase equity in access to health care, reduce reoffending and improve both the health and life chances of these individuals.

Yes / This study was a qualitative case study underpinned by “The Silences Framework” aimed at mapping the ex-offender health pathway towards identifying “touch points” in the community for the delivery of a nurse-led intervention. Participants meeting the study inclusion criteria were quantitatively ranked based on poor health. Participants scoring the lowest and endorsing their ranking through a confirmation of a health condition were selected as cases and interviewed over 6 months. Individuals in the professional networks of offenders contextualized emergent themes. The study indicated that pre-release, offenders were not prepared in prison for the continuity in access to healthcare in the community. On release, reintegration preparation did not routinely enquire whether offenders were still registered with a general practitioner or had the agency to register self in the community. Participants identified the site of post-release supervision as the “touch point” where a nurse-led intervention could be delivered.

Yes / There is global interest in the reconfiguration of community mental health services, including primary care, to improve clinical and cost effectiveness. This study seeks to describe patterns of service use, continuity of care, health risks, physical healthcare monitoring and the balance between primary and secondary mental healthcare for people with severe mental illness in receipt of secondary mental healthcare in the UK. We conducted an epidemiological medical records review in three UK sites. We identified 297 cases randomly selected from the three participating mental health services. Data were manually extracted from electronic patient medical records from both secondary and primary care, for a 2-year period (2012-2014). Continuous data were summarised by mean and s.d. or median and interquartile range (IQR). Categorical data were summarised as percentages. The majority of care was from secondary care practitioners: of the 18 210 direct contacts recorded, 76% were from secondary care (median, 36.5; IQR, 14-68) and 24% were from primary care (median, 10; IQR, 5-20). There was evidence of poor longitudinal continuity: in primary care, 31% of people had poor longitudinal continuity (Modified Modified Continuity Index ≤0.5), and 43% had a single named care coordinator in secondary care services over the 2 years. The study indicates scope for improvement in supporting mental health service delivery in primary care. Greater knowledge of how care is organised presents an opportunity to ensure some rebalancing of the care that all people with severe mental illness receive, when they need it. A future publication will examine differences between the three sites that participated in this study. / This paper presents independent research funded by the National Institute for Health Research (NIHR) under its Programme Grants for Applied Research programme (grant reference no.

This thesis consists of four papers and focuses on function spaces related to first-order analysis in abstract metric measure spaces. The classical (i.e., Sobolev) theory in Euclidean spaces makes use of summability of distributional gradients, whose definition depends on the linear structure of Rn. In metric spaces, we can replace the distributional gradients by (weak) upper gradients that control the functions’ behavior along (almost) all rectifiable curves, which gives rise to the so-called Newtonian spaces. The summability condition, considered in the thesis, is expressed using a general Banach function lattice quasi-norm and so an extensive framework is built. Sobolev-type spaces (mainly based on the Lp norm) on metric spaces, and Newtonian spaces in particular, have been under intensive study since the mid-1990s. In Paper I, the elementary theory of Newtonian spaces based on quasi-Banach function lattices is built up. Standard tools such as moduli of curve families and the Sobolev capacity are developed and applied to study the basic properties of Newtonian functions. Summability of a (weak) upper gradient of a function is shown to guarantee the function’s absolute continuity on almost all curves. Moreover, Newtonian spaces are proven complete in this general setting. Paper II investigates the set of all weak upper gradients of a Newtonian function. In particular, existence of minimal weak upper gradients is established. Validity of Lebesgue’s differentiation theorem for the underlying metric measure space ensures that a family of representation formulae for minimal weak upper gradients can be found. Furthermore, the connection between pointwise and norm convergence of a sequence of Newtonian functions is studied. Smooth functions are frequently used as an approximation of Sobolev functions in analysis of partial differential equations. In fact, Lipschitz continuity, which is (unlike <img src="http://www.diva-portal.org/cgi-bin/mimetex.cgi?%5Cmathcal%7BC%7D%5E1" />-smoothness) well-defined even for functions on metric spaces, often suffices as a regularity condition. Thus, Paper III concentrates on the question when Lipschitz functions provide good approximations of Newtonian functions. As shown in the paper, it suffices that the function lattice quasi-norm is absolutely continuous and a fractional sharp maximal operator satisfies a weak norm estimate, which it does, e.g., in doubling Poincaré spaces if a non-centered maximal operator of Hardy–Littlewood type is locally weakly bounded. Therefore, such a local weak boundedness on rearrangement-invariant spaces is explored as well. Finer qualitative properties of Newtonian functions and the Sobolev capacity get into focus in Paper IV. Under certain hypotheses, Newtonian functions are proven to be quasi-continuous, which yields that the capacity is an outer capacity. Various sufficient conditions for local boundedness and continuity of Newtonian functions are established. Finally, quasi-continuity is applied to discuss density of locally Lipschitz functions in Newtonian spaces on open subsets of doubling Poincaré spaces.

The aim of this master’s thesis is calculation and analysis of reliability indicators of the company E.ON Česká republika, s.r.o. distribution network in the south Moravia territory (area of former Jihomoravská energetika) for the period of one year, from 1st November 2008 to 31st October 2009. We consider events incurred on overhead or underground lines of level of high voltage or directly connected with these lines. Events originated from extensive disaster interruption of electric energy supply caused by particularly unfavourable external effects are not considered, because network components can not be efficiently dimensioned on those influences. Known aspects of the events are time of origin, time duration, place and cause of failure inception. Analysis of reliability indicators is accomplished according to different point of view. The first aspect is the hours of day, during which the event lasted. The second aspect is the hours of day, during which the event incurred. The third one focuses component pointed as reliable for the origin of the event. The last standpoint is percentage load of the line outlet, on which the event occurred. We can ordain this load as the proportion of current flowing through the line outlet in the time of event inception and of the value of maximum current set up on the protection of the line outlet. Indications mentioned in the last sentence were searched in the dispatcher centre thanks to graphical interface of application RIS JME Brno. In the theoretical part of the work there is described the structure of distribution network and its fundamental influence on the continuity of electric energy supply, the ways of evaluation and increasing of electric energy supply reliability, regulation of continuity of electric energy supply with emphasis on regulation in the Czech Republic valid until 26th February 2010 and since 27th February 2010. The last theoretical part focuses on definition of failure and differentiation of failures according to various aspects.

In this thesis the making and experiencing of the exhibition “Sundi Mongo – A village in Congo” is examined through ethnographical interviews with former and present employees at the Museum of Ethnography in Stockholm. The interviews, together with archive material concerning the exhibition, are analyzed with discourse theory in order to examine how discourses of defining Africa construct application and interpretation of the exhibition pieces. A significant element is dislocation, where the exhibition has been standing since 1983 and the meaning of the exhibition is now expressed as changed. This change of meaning is connected to the change of exhibition ideals and changes in the perception of the exhibition model; a real village called Sundi Mongo, located in southwestern Congo. Change and continuity also concerns interpretations of the museum’s cooperation with the Swedish Missionary Association and affective practices surrounding the exhibition pieces and objects in the museum’s collections. The construction of interpretations of the exhibition pieces and objects are also analyzed with the concept of fantasy.

The present study's purpose was to investigate the home care staff's experiences of working as key workers, which factors they consider is relevant to key working and what obstacles and opportunities they experience in their work as a key worker. The study also focused on how the home care staff perceive that key working can enable user influence. A qualitative approach was used and the material for the study was collected through semi-structured interviews. The result shows that there are areas for improvement that may develop key working. The study shows that the staff generally feel that working as a key worker works well and that it can enable user influence in many areas. The study finally illustrates factors such as continuity, working relationship oriented, and taking responsibility, as significant for key working to work as successfully as possible. / Föreliggande studies syfte var att undersöka hemtjänstpersonalens upplevelser av att arbeta med kontaktmannaskap, vilka faktorer de anser är av betydelse för ett fungerade kontaktmannaskap samt vilka hinder och möjligheter de upplever i sitt arbete med kontaktmannaskap.
