Client and therapist variability with psychotherapy homework : a preliminary psychometric evaluation of two scales : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University,
The therapeutic use of homework assignments is an integral feature of Cognitive Behaviour Therapy (CBT) and is believed to be important in producing and maintaining client treatment gains. While there is empirical and theoretical support suggesting that homework completion may be associated with improved outcome, few studies have directly investigated specific therapist behaviours used in the integration of homework into practice. Similarly, research on client homework completion has, by far, focused solely on the quantity of homework completion rather than on any other factors found to be associated with increased client engagement with homework assignments. The recently developed Homework Adherence and Competence Scale (HAACS) was designed to specifically assess therapist competence and adherence to recommended homework behaviours used to administer homework. As a new measure of client homework completion, the Homework Rating Scale-II (HRS-II), extends the assessment of client homework completion beyond quantity only and provides a measure of the cognitive and behavioural determinants of client homework completion. The present study presents a psychometric evaluation of both the HAACS and HRS-II when rated by independent observers. Further, the present study sought to examine therapist differences in adherence and competence in administrating homework as well as investigating the temporal pattern of client homework completion
Disagreement between correlations of quantum mechanics and stochastic electrodynamics in the damped parametric oscillator
Intracavity and external third order correlations in the damped nondegenerate
parametric oscillator are calculated for quantum mechanics and stochastic
electrodynamics (SED), a semiclassical theory. The two theories yield greatly
different results, with the correlations of quantum mechanics being cubic in
the system's nonlinear coupling constant and those of SED being linear in the
same constant. In particular, differences between the two theories are present
in at least a mesoscopic regime. They also exist when realistic damping is
included. Such differences illustrate distinctions between quantum mechanics
and a hidden variable theory for continuous variables.Comment: accepted by PR
Persistent hypertriglyceridemia in statin-treated patients with type 2 diabetes mellitus
Purpose: This paper reports the results of an audit that assessed the prevalence of residual hypertriglyceridemia and the potential need for intensified management among patients with statin-treated type 2 diabetes mellitus (T2DM) in primary care in the UK.
Patients and methods: A cross-sectional, observational, systematic audit of patients with diagnosed diabetes from 40 primary care practices was undertaken. The audit collected basic demographic information and data on prescriptions issued during the preceding 4 months. T2DM patients were stratified according to the proportion that attained European Society of Cardiology treatment targets.
Results: The audit collected data from 14,652 patients with diagnosed diabetes: 89.5% (n = 13,108) of the total cohort had T2DM. Of the people with T2DM, 22.2% (2916) were not currently receiving lipid-lowering therapy. Up to approximately 80% of these people showed evidence of dyslipidemia. Among the group that received lipid-lowering therapy, 94.7% (9647) were on statin monotherapy, which was usually simvastatin (69.5% of patients receiving statin monotherapy; 6707). The currently available statins were prescribed, with the most common dose being 40 mg simvastatin (44.2%; 4267). Irrespective of the statin used, around half of the patients receiving statin monotherapy did not attain the European Society of Cardiology treatment targets for triglycerides, low-density lipoprotein, high-density lipoprotein, and total cholesterol.
Conclusion: T2DM patients managed in UK primary care commonly show persistent lipid abnormalities. Clinicians need to optimize compliance with lipid-lowering and other medications. Clinicians also need to consider intensifying statin regimens, prescribing additional lipid-modifying therapies, and specific treatments aimed at triglyceride lowering to improve dyslipidemia control in statin-treated patients with T2DM
Quantum Teleportation of Optical Quantum Gates
We show that a universal set of gates for quantum computation with optics can
be quantum teleported through the use of EPR entangled states, homodyne
detection, and linear optics and squeezing operations conditioned on
measurement outcomes. This scheme may be used for fault-tolerant quantum
computation in any optical scheme (qubit or continuous variable). The
teleportation of nondeterministic nonlinear gates employed in linear optics
quantum computation is discussed.Comment: 4 pages, 1 figure, published versio

System Design for a Long-Line Quantum Repeater
We present a new control algorithm and system design for a network of quantum
repeaters, and outline the end-to-end protocol architecture. Such a network
will create long-distance quantum states, supporting quantum key distribution
as well as distributed quantum computation. Quantum repeaters improve the
reduction of quantum-communication throughput with distance from exponential to
polynomial. Because a quantum state cannot be copied, a quantum repeater is not
a signal amplifier, but rather executes algorithms for quantum teleportation in
conjunction with a specialized type of quantum error correction called
purification to raise the fidelity of the quantum states. We introduce our
banded purification scheme, which is especially effective when the fidelity of
coupled qubits is low, improving the prospects for experimental realization of
such systems. The resulting throughput is calculated via detailed simulations
of a long line composed of shorter hops. Our algorithmic improvements increase
throughput by a factor of up to fifty compared to earlier approaches, for a
broad range of physical characteristics.Comment: 12 pages, 13 figures. v2 includes one new graph, modest corrections

Signatures of the collapse and revival of a spin Schr\"{o}dinger cat state in a continuously monitored field mode
We study the effects of continuous measurement of the field mode during the
collapse and revival of spin Schr\"{o}dinger cat states in the Tavis-Cummings
model of N qubits (two-level quantum systems) coupled to a field mode. We show
that a compromise between relatively weak and relatively strong continuous
measurement will not completely destroy the collapse and revival dynamics while
still providing enough signal-to-noise resolution to identify the signatures of
the process in the measurement record. This type of measurement would in
principle allow the verification of the occurrence of the collapse and revival
of a spin Schr\"{o}dinger cat state.Comment: 5 pages, 2 figure
