The use of psychotherapy as an effective treatment for grief and loss for persons diagnosed with dementia and their caregiver: a systematic review of the literature
The effects of dementia can be overwhelming not only for those diagnosed with dementia, but also their caregivers. Psychotherapy may be one way that can help the dyad better cope with this life-changing diagnosis, however whether psychotherapy is effective remains unclear. A systematic literature review was conducted to identify effective psychotherapeutic interventions to ameliorate the effects of grief and loss experienced by the dyad of the person experiencing dementia and their caregiver.
During the screening process a total of 1020 records were identified via searching University of Southern Queensland databases using the field 'abstract'. After removing 354 duplicate records a total of 666 remained. Further screening by the researcher and a research assistant resulted in 30 articles being short-listed for full text review using title and abstract. On completion of this procedure it was found that no literature met the inclusion criteria specifically aimed to explore psychotherapy as an effective treatment for grief and loss experienced by the dyad of persons with dementia and their caregiver.
In collaboration with the researcher’s supervisors, a revised inclusion criteria was developed that moved from treatment aimed at the dyad to include research where either the caregiver, or the person with dementia, individually was a recipient of psychotherapeutic intervention. The 666 articles were re-screened and a total of eight articles were short-listed for full-text review. Four of the eight articles were discarded due to not meeting the inclusion criteria. On review it was found that the four articles included for review and synthesis focused on grief and loss experienced by the caregiver. No literature was identified relating to persons with dementia receiving psychotherapeutic intervention to ameliorate the effects of grief and loss.
Within the four articles reviewed and synthesised three interventions were identified as being used. These interventions included: (1) telephone-based cognitive behavioural therapy, (2) coaching, and (3) the five component 'Easing the Way' interventions (MacCourt, McLennan, Somers & Krawczyk, 2017; Meichsner, Schinkothe, & Wilz., 2016; Meichsner & Wilz., 2016; Ott, Kelber, & Blaylock, 2010). These interventions were found to be potentially beneficial in ameliorating the experience of grief and loss on the part of the caregiver. With further research these findings may be useful in its implications in supporting the dyad of caregivers and persons with dementia by guiding the future direction of psychotherapeutic intervention
Relations Between Timing Features and Colors in the X-Ray Binary 4U 0614+09
We study the correlations between timing and X-ray spectral properties in the
low mass X-ray binary 4U 0614+09 using a large (265-ks) data set obtained with
the Rossi X-ray Timing Explorer. We find strong quasi-periodic oscillations
(QPOs) of the X-ray flux, like the kilohertz QPOs in many other X-ray binaries
with accreting neutron stars, with frequencies ranging from 1329 Hz down to 418
Hz and, perhaps, as low as 153 Hz. We report the highest frequency QPO yet from
any low mass X-ray binary at 1329+-4 Hz, which has implications for neutron
star structure. This QPO has a 3.5-sigma single-trial significance, for an
estimated 40 trials the significance is 2.4-sigma. Besides the kilohertz QPOs,
the Fourier power spectra show four additional components: high frequency noise
(HFN), described by a broken power-law with a break frequency between 0.7 and
45 Hz, very low frequency noise (VLFN), which is fitted as a power-law below 1
Hz, and two broad Lorentzians with centroid frequencies varying from 6 to 38 Hz
and 97 to 158 Hz, respectively. We find strong correlations between the
frequencies of the kilohertz QPOs, the frequency of the 6 to 38 Hz broad
Lorentzian, the break frequency of the HFN, the strength of both the HFN and
the VLFN and the position of the source in the hard X-ray color vs. intensity
diagram. The frequency of the 97 to 158 Hz Lorentzian does not correlate with
these parameters. We also find that the relation between power density and
break frequency of the HFN is similar to that established for black hole
candidates in the low state. We suggest that the changing mass accretion rate
is responsible for the correlated changes in all these parameters.Comment: ApJ, referee
Classifying gait alterations using an instrumented smart sock and deep learning
This paper presents a non-invasive method of classifying gait patterns associated with various movement disorders and/or neurological conditions, utilising unobtrusive, instrumented socks and a deep learning network. Seamless instrumented socks were fabricated using three accelerometer embedded yarns, positioned at the toe (hallux), above the heel and on the lateral malleolus. Human trials were conducted on 12 able-bodied participants, an instrumented sock was worn on each foot. Participants were asked to complete seven trials consisting of their typical gait and six different gait types that mimicked the typical movement patterns associated with various movement disorders and neurological conditions. Four Neural Networks and an SVM were tested to ascertain the most effective method of automatic data classification. The Bi-LSTM generated the most accurate results and illustrates that the use of three accelerometers per foot increased classification accuracy compared to a single accelerometer per foot by 11.4%. When only a single accelerometer was utilised for classification, the ankle accelerometer generated the most accurate results in comparison to the other two. The network was able to correctly classify five different gait types: stomp (100%), shuffle (66.8%), diplegic (66.6%), hemiplegic (66.6%) and “normal walking” (58.0%). The network was incapable of correctly differentiating foot slap (21.2%) and steppage gait (4.8%). This work demonstrates that instrumented textile socks incorporating three accelerometer yarns were capable of generating sufficient data to allow a neural network to distinguish between specific gait patterns. This may enable clinicians and therapists to remotely classify gait alterations and observe changes in gait during rehabilitation
Search for Charged Higgs Bosons in Decays of Top Quark Pairs
We present a search for charged Higgs bosons in decays of pair-produced top
quarks using 109.2 +- 5.8 pb^-1 of data recorded from ppbar collisions at
sqrt{s} = 1.8 TeV by the D0 detector during 1992-96 at the Fermilab Tevatron.
No evidence is found for charged Higgs production, and most parts of the
[m(H+),tan(beta)] parameter space where the decay t -> bH+ has a branching
fraction close to or larger than that for t -> bW+ are excluded at 95%
confidence level. Assuming m(t) = 175 GeV and sigma(ppbar -> ttbar) = 5.5 pb,
for m(H+) = 60 GeV, we exclude tan(beta) 40.9.Comment: 11 pages, 3 figures, submitted to PR
Search for Squarks and Gluinos in Events Containing Jets and a Large Imbalance in Transverse Energy
Using data corresponding to an integrated luminosity of 79 pb-1, D0 has
searched for events containing multiple jets and large missing transverse
energy in pbar-p collisions at sqrt(s)=1.8 TeV at the Fermilab Tevatron
collider. Observing no significant excess beyond what is expected from the
standard model, we set limits on the masses of squarks and gluinos and on the
model parameters m_0 and m_1/2, in the framework of the minimal low-energy
supergravity models of supersymmetry. For tan(beta) = 2 and A_0 = 0, with mu <
0, we exclude all models with m_squark < 250 GeV/c^2. For models with equal
squark and gluino masses, we exclude m < 260 GeV/c^2.Comment: 10 pages, 3 figures, Submitted to PRL, Fixed typo on page bottom of

Search for bottom squarks in pbarp collisions at sqrt(s)=1.8 TeV
We report on a search for bottom squarks produced in pbarp collisions at
sqrt(s) = 1.8 TeV using the D0 detector at Fermilab. Bottom squarks are assumed
to be produced in pairs and to decay to the lightest supersymmetric particle
(LSP) and a b quark with branching fraction of 100%. The LSP is assumed to be
the lightest neutralino and stable. We set limits on the production cross
section as a function of bottom squark mass and LSP mass.Comment: 5 pages, Latex. submitted 3-12-1999 to PRD - Rapid Communicatio
The geographies of access to enterprise finance: the case of the West Midlands, UK
The geographies of access to enterprise finance: the case of the West Midlands, UK, Regional Studies. Whilst there is a long history of credit rationing to small and medium-sized enterprises (SMEs) in the UK, the financial crisis has seen banks retreat further from lending to viable SMEs due to a reassessment of risk and lack of available capital. In so doing, the credit crunch is thought to be creating new geographies of financial exclusion. This paper explores the financial inclusion of enterprise through community development finance institutions (CDFIs) which provide loan finance to firms at the commercial margins in the West Midlands, UK. The paper concludes that CDFIs could partially address the financial exclusion of enterprise as an additional, alternative source of finance to that of mainstream banks
Spin Correlation in tt-bar Production from pp-bar Collisions at sqrt(s)=1.8 TeV
The D0 collaboration has performed a study of spin correlation in tt-bar
production for the process tt-bar to bb-bar W^+W^-, where the W bosons decay to
e-nu or mu-nu. A sample of six events was collected during an exposure of the
D0 detector to an integrated luminosity of approximately 125 pb^-1 of
sqrt{s}=1.8 TeV pp-bar collisions. The standard model (SM) predicts that the
short lifetime of the top quark ensures the transmission of any spin
information at production to the tt-bar decay products.
The degree of spin correlation is characterized by a correlation coefficient
k. We find that k>-0.25 at the 68% confidence level, in agreement with the SM
prediction of k=0.88.Comment: Submitted to PRL, Added references, minor changes to tex
Probing BFKL Dynamics in the Dijet Cross Section at Large Rapidity Intervals in ppbar Collisions at sqrt{s}=1800 and 630 GeV
Inclusive dijet production at large pseudorapidity intervals (delta_eta)
between the two jets has been suggested as a regime for observing BFKL
dynamics. We have measured the dijet cross section for large delta_eta in ppbar
collisions at sqrt{s}=1800 and 630 GeV using the DO detector. The partonic
cross section increases strongly with the size of delta_eta. The observed
growth is even stronger than expected on the basis of BFKL resummation in the
leading logarithmic approximation. The growth of the partonic cross section can
be accommodated with an effective BFKL intercept of
a_{BFKL}(20GeV)=1.65+/-0.07.Comment: Published in Physical Review Letter
Measurement of the Top Quark Pair Production Cross Section in the All-jets Decay Channel
We present a measurement of tbar-t production using multijet final states in
pbar-p collisions at a center-of-mass energy of 1.8 TeV, with an integrated
luminosity of 110.3 pb(-1). The analysis has been optimized using neural
networks to achieve the smallest expected fractional uncertainty on the tbar-t
production cross section, and yields a cross section of 7.1 +/- 2.8(stat.) +/-
1.5(syst.) pb, assuming a top quark mass of 172.1 GeV/c^(2). Combining this
result with previous D0 measurements, where one or both of the W bosons decay
leptonically, gives a tbar-t production cross section of 5.9 +/- 1.2(stat) +/-
1.1(syst) pb.Comment: 6 pages, 3 figures; no substative change in revisio
