The Developing Methodology for Analyzing Privacy Torts

The authors assert the need for a common method of analyzing privacy situations that can be applied consistently by practitioners, juries and courts. They contend that confusion exists as to the legal basis of privacy torts because the right of privacy, as originally conceived by Warren and Brandeis, was never adequately defined. Prosser\u27s analysis of privacy torts departs from the Warren and Brandeis formulation and, according to the authors, also can be criticized for lack of definition. The authors present a new methodology that analyzes privacy torts based upon the scope of consent standard. They maintain that the result will be the protection of the right of privacy as originally conceived by Warren and Brandeis

Social problem solving, cognitive defusion and social identification in wellness recovery action planning

Objective: The concept of recovery has become an integral part of modern mental health care. Understanding the outcomes and underlying mechanisms of key recovery interventions, such as Wellness Recovery Action Planning (WRAP), is essential in order to expand the theoretical understanding of recovery and inform how to target recovery in treatment. Therefore a systematic review of the literature was conducted to evaluate the mental health outcomes of WRAP for adults. The empirical study then explored three constructs in relation to WRAP and recovery. These were social problem solving, cognitive defusion and social identification. Method: The systematic review of the mental health outcomes of WRAP was conducted by searching four databases, contacting the authors of WRAP research and seeking evaluative information from organisations that deliver WRAP. Fourteen relevant studies met the inclusion criteria. Whereas, the empirical study recruited participants on a trans-diagnostic basis from across Scotland. Using a quantitative cross sectional design, 109 participant’s completed 5 self-report questionnaires. These were the Knowledge, Attitudes and Beliefs about WRAP Questionnaire (WRAP beliefs), the Recovery Assessment Scale – Short (RAS-S), the Social Problem Solving Inventory - Revised - Short (SPSI-R-S), the Four Item Measure of Social Identification (FISI) and the Cognitive Fusion Questionnaire (CFQ). Correlation, regression and mediation analysis were used to explore relationships, and in particular, the predictors and mediators of recovery. Results: The systematic review provided strong evidence that WRAP has a significant positive impact on hope and also reduces the symptoms of mental illness. However, whether WRAP improves personal levels of recovery was unclear and a possible risk of disempowerment was found. Promising preliminary mental health outcomes in the areas of confidence in managing mental health, quality of life, service use, self-advocacy and knowledge attitudes and beliefs about recovery were highlighted. Only studies that did not use peer facilitators failed to find significant increases in hope compared to treatment as usual control groups. In the empirical study, the results indicated that all the constructs examined were correlated to recovery. In the regression analysis, WRAP beliefs, social problem solving and cognitive defusion also demonstrated a predictive relationship with recovery. Mediation analysis indicated that, social problem solving mediated two distinct relationships. One between WRAP beliefs and recovery, and another between cognitive defusion and recovery. The social problem solving subscales also showed how the two predictors relate to recovery through social problem solving in different ways. Social identification with the WRAP group did not significantly predict or mediate recovery. Conclusions: The systematic review indicated having peer facilitators delivering WRAP is key to helping participants foster hope and that a further randomised control trial could help clarify if improved personal recovery is an outcome of WRAP. It additionally suggested how the relationship between WRAP beliefs and recovery could be explored, as per the design of the empirical study. Findings from the empirical study implied that improving participants’ social problem solving and cognitive defusion should be specifically targeted in WRAP delivery. The studies combined indicate that to achieve the best recovery results interventions, like WRAP, should target inspiring hope through peer support, improving knowledge, attitudes and beliefs about recovery and cognitive defusion from unhelpful thoughts

Three-dimensional forced-damped dynamical systems with rich dynamics : bifurcations, chaos and unbounded solutions

T.M. is supported by the Grant-in-Aid for JSPS Fellow No. 24·5312. H.O. is partially supported by JSPS KAKENHI 24244007.We consider certain autonomous three-dimensional dynamical systems that can arise in mechanical and fluid-dynamical contexts. Extending a previous study in Craik and Okamoto (2002), to include linear forcing and damping, we find that the four-leaf structure discovered in that paper, and unbounded orbits, persist, but may now be accompanied by three distinct period-doubling cascades to chaos, and by orbits that approach stable equilibrium points. This rich structure is investigated both analytically and numerically, distinguishing three main cases determined by the damping and forcing parameter values.PostprintPeer reviewe

Headache

From a dissertation read before the Society on February 4th, 1966.Headache is a symptom which may be a feature of a wide range of conditions, arising not only with pathology in the head but also in cardio-vascular, renal, metabolic, orthopaedic and psychiatric conditions. It is extremely common, and usually transitory. Yet it may be a symptom of great significance in clinical practice. The underlying mechanisms are largely unknown. The explanations of the cause of headaches have a long history, and it is on the aetiology of headache that this discussion will centre.Headache can be a dramatic symptom and presumably has been ever since primitive man drank a fermented juice to excess and had his first hangover, or woke up with his first postconcussional headache to find that his wife had been kidnapped

Prediction for the He I 10830A Absorption Wing in the Coming Event of Eta Carinae

We propose an explanation to the puzzling appearance of a wide blue absorption wing in the He I 10830A P-Cygni profile of the massive binary star Eta Carinae several months before periastron passage. Our basic assumption is that the colliding winds region is responsible for the blue wing absorption. By fitting observations, we find that the maximum outflow velocity of this absorbing material is ~2300 km/s. We also assume that the secondary star is toward the observer at periastron passage. With a toy-model we achieve two significant results. (1) We show that the semimajor axis orientation we use can account for the appearance and evolution of the wide blue wing under our basic assumption. (2) We predict that the Doppler shift (the edge of the absorption profile) will reach a maximum 0-3 weeks before periastron passage, and not necessarily exactly at periastron passage or after periastron passage.Comment: 15 pages, 6 figures.

Episodic Post-Shock Dust Formation in the Colliding Winds of Eta Carinae

Eta Carinae shows broad peaks in near-infrared (IR) JHKL photometry, roughly correlated with times of periastron passage in the eccentric binary system. After correcting for secular changes attributed to reduced extinction from the thinning Homunculus Nebula, these peaks have IR spectral energy distributions (SEDs) consistent with emission from hot dust at 1400-1700 K. The excess SEDs are clearly inconsistent, however, with the excess being entirely due to free-free wind or photospheric emission. One must conclude, therefore, that the broad near-IR peaks associated with Eta Carinae's 5.5 yr variability are due to thermal emission from hot dust. I propose that this transient hot dust results from episodic formation of grains within compressed post-shock zones of the colliding winds, analogous to the episodic dust formation in Wolf-Rayet binary systems like WR140 or the post-shock dust formation seen in some supernovae like SN2006jc. This dust formation in Eta Carinae seems to occur preferentially near and after periastron passage; near-IR excess emission then fades as the new dust disperses and cools. With the high grain temperatures and Eta Car's C-poor abundances, the grains are probably composed of corundum or similar species that condense at high temperatures, rather than silicates or graphite. Episodic dust formation in Eta Car's colliding winds significantly impacts our understanding of the system, and several observable consequences are discussed.Comment: MNRAS accepted; 8 pages, 5 figs, 2 color fig

In Hot Pursuit of the Hidden Companion of Eta Carinae: An X-ray Determination of the Wind Parameters

We present X-ray spectral fits to a recently obtained Chandra grating spectrum of Eta Carinae, one of the most massive and powerful stars in the Galaxy and which is strongly suspected to be a colliding wind binary system. Hydrodynamic models of colliding winds are used to generate synthetic X-ray spectra for a range of mass-loss rates and wind velocities. They are then fitted against newly acquired Chandra grating data. We find that due to the low velocity of the primary wind (~500 km/s), most of the observed X-ray emission appears to arise from the shocked wind of the companion star. We use the duration of the lightcurve minimum to fix the wind momentum ratio at 0.2. We are then able to obtain a good fit to the data by varying the mass-loss rate of the companion and the terminal velocity of its wind. We find that Mdot ~ 1e-5 Msol/yr and v ~ 3000 km/s. With observationally determined values of ~500-700 km/s for the velocity of the primary wind, our fit implies a primary mass-loss rate of Mdot ~ 2.5e-4 Msol/yr. This value is smaller than commonly inferred, although we note that a lower mass-loss rate can reduce some of the problems noted by Hillier et al. (2001) when a value as high as 1e-3 Msol/yr is used. The wind parameters of the companion are indicative of a massive star which may or may not be evolved. The line strengths appear to show slightly sub-solar abundances, although this needs further confirmation. Based on the over-estimation of the X-ray line strengths in our model, and re-interpretation of the HST/FOS results, it appears that the homunculus nebula was produced by the primary star.Comment: 12 pages, 7 figures, accepted by A&

Integrated analysis of Wnt signalling system component gene expression

Wnt signalling controls patterning and differentiation across many tissues and organs of the developing embryo through temporally and spatially restricted expression of multi-gene families encoding ligands, receptors, pathway modulators and intracellular components. Here, we report an integrated analysis of key genes in the 3D space of the mouse embryo across multiple stages of development. We applied a method for 3D/3D image transformation to map all gene expression patterns to a single reference embryo for each stage, providing both visual analysis and volumetric mapping allowing computational methods to interrogate the combined expression patterns. We identify territories where multiple Wnt and Fzd genes are co-expressed and cross-compare all patterns, including all seven Wnt paralogous gene pairs. The comprehensive analysis revealed regions in the embryo where no Wnt or Fzd gene expression is detected, and where single Wnt genes are uniquely expressed. This work provides insight into a previously unappreciated level of organisation of expression patterns, as well as presenting a resource that can be utilised further by the research community for whole-system analysis

Determination of metal ion concentrations by SERS using 2,2’-bipyridyl complexes

Surface enhanced Raman scattering (SERS) can generate characteristic spectral “fingerprints” from metal complexes, thus providing the potential for the development of methods of analysis for the identification and quantitation of a range of metal ions in solution. The advantages include sensitivity and the use of one ligand for several metals without the need for a specific chromophore. Aqueous solutions of Fe(II), Ni(II), Zn(II), Cu(II), Cr(III) and Cd(II) in the presence of excess 2,2′-bipyridyl (bipy) were analysed using SERS. Specific marker bands enabled the identification of each metal ion and the limit of detection for each metal ion was estimated. Two of the ions, Zn(II) and Cu(II), could be detected below the World Health Organisation's (WHO) recommended limits for drinking water at levels of 0.22 and 0.6 mg L−1, respectively

Constraining the Absolute Orientation of Eta Carinae's Binary Orbit: A 3-D Dynamical Model for the Broad [Fe III] Emission

We present a three-dimensional (3-D) dynamical model for the broad [Fe III] emission observed in Eta Carinae using the Hubble Space Telescope/Space Telescope Imaging Spectrograph (HST/STIS). This model is based on full 3-D Smoothed Particle Hydrodynamics (SPH) simulations of Eta Car's binary colliding winds. Radiative transfer codes are used to generate synthetic spectro-images of [Fe III] emission line structures at various observed orbital phases and STIS slit position angles (PAs). Through a parameter study that varies the orbital inclination i, the PA {\theta} that the orbital plane projection of the line-of-sight makes with the apastron side of the semi-major axis, and the PA on the sky of the orbital axis, we are able, for the first time, to tightly constrain the absolute 3-D orientation of the binary orbit. To simultaneously reproduce the blue-shifted emission arcs observed at orbital phase 0.976, STIS slit PA = +38 degrees, and the temporal variations in emission seen at negative slit PAs, the binary needs to have an i \approx 130 to 145 degrees, {\theta} \approx -15 to +30 degrees, and an orbital axis projected on the sky at a PA \approx 302 to 327 degrees east of north. This represents a system with an orbital axis that is closely aligned with the inferred polar axis of the Homunculus nebula, in 3-D. The companion star, Eta B, thus orbits clockwise on the sky and is on the observer's side of the system at apastron. This orientation has important implications for theories for the formation of the Homunculus and helps lay the groundwork for orbital modeling to determine the stellar masses.Comment: 23 pages, 12 color figures, plus 2 online-only appendices (available in the /anc folder of the Source directory).
