The experiences of sharing a diagnosis of young onset dementia with others
Section A reviews research literature on experiences of self-disclosing a life-limiting illness to others. It summarises the complex processes that frames self-disclosure as a series of ongoing events across a range of relationships: how people self-disclose, motivations for self-disclosure and concealment, helpful and unhelpful experiences and gender and age differences in selfdisclosure. Among clinical implications is the need for a balanced view between selfdisclosure and concealment for individuals to cope with difficulties and maintain a sense of control and their sense of self when faced with vulnerability from a life-limiting illness. Only a few studies suggest or recommend support for self-disclosure. Research implications include a need for longitudinal research to follow the evolution of self-disclosure decision making and relationships, to incorporate quantitative facets within studies of disclosure process, and to examine disclosure for different life-limiting illnesses.
Section B explores, from the perspective of individuals with young onset dementia (YOD), what happens to relationships when individuals share their YOD diagnosis, and the renegotiation of relationships with others as dementia progresses. The journey from prediagnosis to living with YOD was examined. Grounded theory methodology was used analyse the processes of receiving and understanding a diagnosis, sharing the diagnosis to others, negotiating a shared understanding with others and living with dementia. The findings revealed complex challenges faced by individuals with YOD as the condition progresses. The impact of self-disclosure on relationships and the sense of self was considered. The distinct experiences of YOD due to overlapping life stages and dissimilarities to chronic mental and physical health conditions suggests the need for YOD specific services. Clinical and research implications were discussed based on the findings and existing literature
Delaunay Edge Flips in Dense Surface Triangulations
Delaunay flip is an elegant, simple tool to convert a triangulation of a
point set to its Delaunay triangulation. The technique has been researched
extensively for full dimensional triangulations of point sets. However, an
important case of triangulations which are not full dimensional is surface
triangulations in three dimensions. In this paper we address the question of
converting a surface triangulation to a subcomplex of the Delaunay
triangulation with edge flips. We show that the surface triangulations which
closely approximate a smooth surface with uniform density can be transformed to
a Delaunay triangulation with a simple edge flip algorithm. The condition on
uniformity becomes less stringent with increasing density of the triangulation.
If the condition is dropped completely, the flip algorithm still terminates
although the output surface triangulation becomes "almost Delaunay" instead of
exactly Delaunay.Comment: This paper is prelude to "Maintaining Deforming Surface Meshes" by

An Extended Accelerator Model of R&D and Physical Investment
Using a multivariate autoregressive framework, we have found a simple causal structure for the variables of interest q, s, r, and i, which is consistent with our data. As expected from the stock market efficiency hypothesis, q, the stock market one period holding rate of return, is exogenous relative to the other three variables (or Granger causes them). As postulated in the traditional accelerator model of investment, the rate of growth of sales, s, can be also treated as exogenous to the rates of growth of R&D and physical. investment, r and i. Moreover, no strong feed- back interaction is detected between the last two (r and i). Within the simple structure of the extended accelerator model, the substantive conclusion is that R&D and physical investment react very similarly to the growth of the sales and to movements in q; the response of R&D is, however, more stable or less irregular than that of physical investment. Expected demand and expected profitability thus both appear to be important determinants for R&D expenditures and physical investment.
One Dimensional ary Density Classification Using Two Cellular Automaton Rules
Suppose each site on a one-dimensional chain with periodic boundary condition
may take on any one of the states , can you find out the most
frequently occurring state using cellular automaton? Here, we prove that while
the above density classification task cannot be resolved by a single cellular
automaton, this task can be performed efficiently by applying two cellular
automaton rules in succession.Comment: Revtex, 4 pages, uses amsfont
Finding The Sign Of A Function Value By Binary Cellular Automaton
Given a continuous function , suppose that the sign of only has
finitely many discontinuous points in the interval . We show how to use
a sequence of one dimensional deterministic binary cellular automata to
determine the sign of where is the (number) density of 1s in
an arbitrarily given bit string of finite length provided that satisfies
certain technical conditions.Comment: Revtex, uses amsfonts, 10 page
The Effectiveness of a Structural-cum-Communicative Approach to Vocabulary Teaching
This study aims to investigate the effectiveness of a structural-cum-communicative approach to the teaching of vocabulary to students possessing a low level of English proficiency. A total of 52 foundation degree students taking a 13-week preparatory reading and writing course participated in the present study. Both the control and the experimental groups took a pre-test and a post-test. The pre-test contained two parts, each of which included 25 words and a list of 25 definitions for students to select. The same format applied to the post-test. Both groups of participants were taught word-formation knowledge at the initial stage. However, at the later stage of actually teaching target words, the experimental group was engaged in brief conversations on topics related to their daily life with respect to the target words while the control group was provided with explanations only in the teaching process.Paired Samples T-Tests show that only the experimental group scored significantly higher on the post-test than on the pre-test. The findings suggest that the teaching of word-formation knowledge as well as engaging students in conversations related to the target words seems to constitute an effective pedagogical approach to vocabulary building for students possessing a low level of English proficiency
