Experiences of shame for people with dementia: An Interpretative Phenomenological Analysis
Studies highlight that shame can be problematic for people with early-stage dementia. However, no published research has specifically explored experiences of shame in dementia from the perspective of the individual. This study uses Interpretative Phenomenological Analysis to gain an understanding of how shame is experienced and made sense of by six people with early-stage dementia. Individual, semi-structured interviews took place in participantsâ homes. An in-depth analysis of the data revealed four superordinate themes implicated in shame experiences: Avoidance explains the participantsâ efforts to distance themselves from shaming experiences; participants reported Negative self-perceptions including a weakening self, loss of value and meaninglessness; Relationship matters involved issues around trust, burden and past relationships and Uncertainty and loss of control highlights participantsâ anxiety about losing clarity and control. Ideas are contributed for promoting non-shaming experiences for people with dementia, particularly through communication during assessment and diagnosis, and psychological therapies
Performance Optimization in Video Transmission over ZigBee using Particle Swarm Optimization
IEEE 802.15.4 - ZigBee is a wireless sensor targeted at applications that require low data rate, low power and inexpensive. IEEE 802.15.4 is limited to a throughput of 250kbps and is designed to provide highly efficient connec-tivity. Hence, IEEE 802.15.4 is not designed to transfer large amounts of da-ta or MPEG-4 as its bandwidth is too low. In engineering and computer sci-ence often use optimization techniques, as do real environment applications in order to overcome complex issues and now this paper a solution has been accomplished by applying Particle Swarm Optimization (PSO) to improve the quality of transmitted MPEG-4 over IEEE 802.15.4. The proposed intelligent system should minimize data loss and distortion. The computer simulation results confirm that applying PSO in video transmission improve the quality of picture and reduce data loss when compared with the conventional MPEG video transmission in ZigBee
Effects of long-range Coulomb interaction on the quantum transport in fractional quantum Hall edges
We study the effects of long-range Coulomb interaction (LRCI) on the quantum
transport in FQH edges with . We consider two models, i.e., the
quasi-particle tunneling (QPT) model and the electron tunneling (ET) model at
the point contact. The tunneling conductance is obtained using the
renormalization group treatment. In QPT model, it is found that LRCI further
reduces below a crossover temperature . In ET model, on the
other hand, there is a temeperature region where LRCI enhances , and
nonmonotonic temperature dependence is possible.Comment: 4 pages, latex file. Published in Solid State Commun.103, 663 (1997).
There is a typo in the effective action for the ET model in the earlier
version. should be replaced by $1/\nu
Non-Perturbative Renormalization Group Analysis of the Ohmic Quantum Dissipation
We analyze quantum tunneling with the Ohmic dissipation by the
non-perturbative renormalization group method. We calculate the localization
susceptibility to evaluate the critical dissipation for the quantum-classical
transition, and find considerably larger critical dissipation compared to the
previous semi-classical arguments.Comment: Latex 9 pages, 3 eps figures, final versio
Racial and Ethnic Differences in Directâ toâ Consumer Genetic Tests Awareness in HINTS 2007: Sociodemographic and Numeracy Correlates
To examine the association of 1) race/ethnicity and 2) numeracy with awareness of DTC genetic tests. Secondary analysis of 6,754 Hispanic, black, and white adult respondents to the National Cancer Instituteâs 2007 Health Information National Trends Survey (HINTS). Logistic regression was used to examine sociodemographic predictors of DTC genetic tests awareness including race/ethnicity, income, education, and gender. Next, two numeracy variables were added to the model. After controlling for sociodemographic variables, black respondents were significantly less likely to have heard of DTC genetic tests compared to white respondents (ORâ =â 0.79; CI: 0.65â 0.97). When numeracy variables were added to the model, the effect of black race was no longer significant (ORâ =â 0.84; CI: 0.69â 1.04). Hispanic respondents did not significantly differ from white respondents in awareness of DTC genetic tests. Other significant correlates of DTC genetic tests awareness in the full model included education, income, age, and numeracy variables including degree to which people use medical statistics and numbers to make health decisions, and preference for words or numbers when discussing â the chance of something happening.â Although black respondents were generally less aware of DTC genetic tests than white respondents, this relationship appears to be partially mediated by numeracy.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146912/1/jgc40440.pd

Mississippi Canyon 252 Incident NRDA Tier 1 for Deepwater Communities
The northern Gulf of Mexico (GOM) is geologically diverse basin, described as the most complex continental slope region in the world. Regional topography of the slope consists of basins, knolls, ridges, and mounds derived from the dynamic adjustments of salt and the introduction of large volumes of sediment over long time scales. More than 99% of the sea floor in the GOM consists of soft sediment made up of various mixtures of primarily silt and clay. These wide-spread soft bottom communities are described in reports from major MMS studies by Gallaway et al. (1998) and Rowe and Kennicutt (2009). Relative to soft bottoms, hard bottoms and their associated communities are relatively uncommon by are notable for their high biodiversity and complexity
Characterization of Microbial Communities in Subsurface Nuclear Blast Cavities of the Nevada Test Site
This U.S. Department of Energy (DOE) Environmental Remediation Sciences Project (ERSP) was designed to test fundamental hypotheses concerning the existence and nature of indigenous microbial populations of Nevada Test Site subsurface nuclear test/detonation cavities. Now called Subsurface Biogeochemical Research (SBR), this programâs Exploratory Research (ER) element, which funded this research, is designed to support high risk, high potential reward projects. Here, five cavities (GASCON, CHANCELLOR, NASH, ALEMAN, and ALMENDRO) and one tunnel (U12N) were sampled using bailers or pumps. Molecular and cultivation-based techniques revealed bacterial signatures at five sites (CHANCELLOR may be lifeless). SSU rRNA gene libraries contained diverse and divergent microbial sequences affiliated with known metal- and sulfur-cycling microorganisms, organic compound degraders, microorganisms from deep mines, and bacteria involved in selenate reduction and arsenite oxidation. Close relatives of Desulforudis audaxviator, a microorganism thought to subsist in the terrestrial deep subsurface on H2 and SO42- produced by radiochemical reactions, was detected in the tunnel waters. NTS-specific media formulations were used to culture and quantify nitrate-, sulfate-, iron-reducing, fermentative, and methanogenic microorganisms. Given that redox manipulations mediated by microorganisms can impact the mobility of DOE contaminants, our results should have implications for management strategies at this and other DOE sites
Creativity and the computer nerd: an exploration of attitudes
This study arises from our concern that many of our best art and design students are failing to make the most of the opportunities provided by IT because of their fear or dislike of computers. This not only deprives them of useful skills, but, even more importantly, deprives many IT based developments of their input. In this paper we investigate the relationship between attitudes to creativity and to computers among students. We quickly discard an approach based on theories of personality types as philosophically and educationally problematic. An approach based on the self-concept of artists and designers, in relation to their own creativity and to their feelings about computers, offers more hope of progress. This means that we do not try to define the attributes of "creative people". Rather, we ask what creativity means to students of art and design and relate these responses to their attitudes to computers. Self-concept depends on how the subjects see themselves within society and culture, and is liable to change as culture changes. One major instrument of cultural change at the present time is the growth of IT itself. We then describe a first attempt at using a psychological method - Kelly's Repertory Grids - to investigate the self-concept of artists and designers. It is hoped to continue with this approach in further studies over the next few years
