TA Treatment of Emetophobia: A Hermeneutic Single-Case Efficacy Design Study – ‘Peter’
Authors: Kerr Colin 
Published: November 2017

This study reports on theapplication of Hermeneutic Single Case Efficacy Design (HSCED) (Elliott 2002) to a 39 session TA-based psychotherapy intervention with a 19 year old white male student in the UK who was suffering from emetophobia. The author, who was also the researcher, provides literature reviews on emetophobia clinical characteristics,contrasts it with other phobias, and reviews prior research including TA-based approaches to phobias generally. HSCED Methodology is briefly described; quantitative outcome measures are obtained and analysed using GAD-7 (Spritzer et al 2006)and SPQ (Elliott et al 1999), and qualitative measures via a rich case record, session recordings/transcripts, and a 4-month follow-up interview. Bohart at al’s (2011) 56 criteria for evidence adjudication were used alongside HSCED criteria. There was strong evidence of significant client changes, and that these changes were the result of the therapy.
Application of Redecision Therapy in Executive Coaching Workshops: Part 1 – the Workshop
Authors: Rosseau Mil , Rosseau Rik , Widdowson Mark 
Published: November 2017

First in a series of three, this paper describes how the redecision approach (Goulding & Goulding 1979) has been applied over many years within executive coaching workshops internationally. The potential controversy about using a therapeutic approach in a business context is addressed, participant profiles and leadership characteristics are described, the impact of the group environment is considered, and the links between working on ‘problems’ and Berne’s (1961) stages of cure are explained. The stages of working are related to those described by Goulding & Goulding (1979) and supplemented with material from McNeel (1999-2000) and Allen & Allen (2002). This paper describes the interventions that are evaluated qualitatively by Widdowson & Rosseau (2014) and that will be further evaluated quantitatively in the future.
Transactional Analysis Psychotherapy for a Case of Mixed Anxiety & Depression: A Pragmatic Adjudicated Case Study – ‘Alastair’
Authors: Widdowson Mark 
Published: November 2017

Using an original method of case evaluation which involved an analysis panel of over 80 Italian psychologists and included a lay case evaluation, the author has investigated the effectiveness of transactional analysis psychotherapy for a case of mixed anxiety and depression with a 39 year old white British male who attended 14 weekly sessions. CORE-OM (Evans, Mellor-Clark , Margison, Barkham, Audin, Connell and McGrath, 2000), PHQ-9 (Kroenke, Spitzer & Williams, 2001), GAD-7) Spitzer, Kroenke, Williams & Löwe, 2006, Hamilton Rating Scale for Depression (Hamilton, 1980) were used for screening and also for outcome measurement, along with Session Rating Scale (SRS v.3.0) (Duncan, Miller, Sparks, Claud, Reynolds, Brown and Johnson, 2003) and Comparative Psychotherapy Process Scale (CPPS) (Hilsenroth, Blagys, Ackerman, Bonge and Blais, 2005), within an overall adjudicational case study method. The conclusion of the analysis panel and the lay judge was unanimously that this was a good outcome case and that the client’s changes had been as a direct result of therapy. Previous case study research has demonstrated that TA is effective for depression, and this present case provides foundation evidence for the effectiveness of TA for depression with comorbid anxiety.
An action research project aimed at raising social consciousness amongst women attending transactional analysis group psychotherapy in Brazil
Authors: Costa Jane Maria Pancinha 
Published: November 2017

Based on awareness of material by Gramsci (1978, 1982) on hegemony, Freire (1979a, 1979b) on cooperative contact, and Steiner (1975) on radical psychiatry, action research methodology was used by the researcher, who was also a psychotherapist, with 12 women attending two ongoing weekly psychotherapy groups in Brazil in order to raise their social consciousness of culturally-based oppression of women, particularly relating to work; to apply life script analysis as a therapeutic intervention within the groups; and to facilitate recognition by the women of the benefits of cooperative contact when seeking to liberate themselves from oppression. Individual structured interviews were conducted and the data from these was discussed within the groups, leading to the development of a model containing 6 levels of consciousness of oppression. Examples of oppression identified by the women are provided, with only 17% relating directly to sexual discrim-ination at work. Although the research was conducted many years ago (1987-1989), it is shown that problems still exist and the research method-ology could usefully be applied elsewhere.
An in-depth exploration of the experience and sense-making of transactional analyst psychotherapists working with clients who present with Internet addiction
Authors: Shorrock Matthew 
Published: November 2017

Four internationally-accredited transactional analysis psychotherapists completed semi—structured one-to-one interviews that explored their experiences and sense-making of Internet addiction (IA). Interpretive phenomenological analysis yielded four higher-order concepts: the complexity of IA; aetiological and predisposing factors; functions and features of IA; and treatment factors. Practical and theoretical implications for future research, clinical supervision, treatment, psycho-educational and political programmes are presented. Of the key emergent findings the Internet was understood by participants as a conduit or medium for addiction given a high prevalence of an underlying ‘disorder’. It was also found that participants believed in the existence of childhood aetiological roots underpinning comorbidity with IA; that attachment difficulties in childhood often predispose individuals to develop issues around loneliness, low self-esteem, control, loss, instability and cognitive dissonance later in life; and that a relationship exists between depression, low self-esteem and escapism as contributing factors. It is concluded that professionals would benefit from specific trainings concerning childhood attachment difficulties, whilst integrating a psychodynamic approach, or being aware of transference processes, could enhance treatment effectiveness and help safeguard both clients and therapists from counter-therapeutic interventions.
Influence of surface microstructure and chemical compositions on grooving corrosion of carbon steel welded joints
Authors: Lu Yongxin , Li Xiao , Xu Lianyong , Jing Hongyang , Han Yongdian 
Published: November 2017

Abstract
Corrosion behavior of a welded joint is complicated and can be strongly dependent on its local chemical composition and microstructure of the surface. To gain a thorough insight into the grooving corrosion behavior of welded joint, it is necessary to understand the corrosion mechanism of different regions of the welded joint. In this study, the influence of the lattice constant on the electron work function (EWF) and corrosion rate of base metal and two weld metals was investigated using a constant potential polarization approach and a scanning Kelvin probe (SKP). Experimental results showed that surface EWF decreased with increasing lattice constant, whereas the corrosion rate increased with an increase in lattice constant. At the same time, it was theoretically demonstrated that the lattice constant can affect the local EWF fluctuation of a welded joint. The fluctuation further leads to the corrosion rate difference of the different regions of the welded joint. So, the lattice constant change in the surface structure is a possible reason for the average grooving susceptibility coefficient difference of two kinds of welded joint. Besides, the alloying elements distribution of two kinds of welded joint zones should be a main reason for the average grooving susceptibility coefficient difference of joints verified by the EPMA measurements and the quantitative calculatinon of the contents of Cu, Ni and Si in the joints.
Anatomical Variation Of The Submandibular Gland Duct. A Unreported Anomaly
Authors: Ferreira Arquez Humberto 
Published: November 2017

Background: The submandibular gland is the second largest major salivary gland and weighs 7–16 gr. The gland is located in both sides of the face, at the same level of the body of the jaw, in the submandibular triangle, The submandibular duct or Wharton’s duct exits anteriorly, coursing deep to the lingual nerve and medial to the sublingual gland, the main excretory duct of the submandibular gland, whose diameter is of 2 to 3mm and approximately 4–5 cm long. It empties lateral to the lingual frenulum through a papilla in the floor of the mouth behind the lower incisor tooth. The purpose of this study is determine the morphologic features and describe an unusual anatomical variation of the path of the submandibular duct.
Methods and Findings: A total of 17 cadavers were used for this study in the Morphology Laboratory at the University of Pamplona. In a cadaver were findings: The excretory duct of the left submandibular gland had an external location that ascends and crosses vertically off the body of the mandible, in its termination it is divided in four ducts that had separate openings into the oral cavity upon a small papillas independent, opposites to the first and second lower molar Crown.
Conclusions: Awareness of potential variations of the excretory ducts of the salivary glands can aid in the accurate diagnosis and treatment of patients with salivary conditions as well as help surgeons avoid further complications or duct lacerations during surgical procedures.
Exterior Companions to Hot Jupiters Orbiting Cool Stars Are Coplanar
Authors: Becker Juliette C. , Vanderburg Andrew , Adams Fred C. , Khain Tali , Bryan Marta 
Published: November 2017

Abstract
The existence of hot Jupiters has challenged theories of planetary formation since the first extrasolar planets were detected. Giant planets are generally believed to form far from their host stars, where volatile materials like water exist in their solid phase, making it easier for giant planet cores to accumulate. Several mechanisms have been proposed to explain how giant planets can migrate inward from their birth sites to short-period orbits. One such mechanism, called Kozai–Lidov migration, requires the presence of distant companions in orbits inclined by more than ∼40° with respect to the plane of the hot Jupiter’s orbit. The high occurrence rate of wide companions in hot-Jupiter systems lends support to this theory for migration. However, the exact orbital inclinations of these detected planetary and stellar companions is not known, so it is not clear whether the mutual inclination of these companions is large enough for the Kozai–Lidov process to operate. This paper shows that in systems orbiting cool stars with convective outer layers, the orbits of most wide planetary companions to hot Jupiters must be well aligned with the orbits of the hot Jupiters and the spins of the host stars. For a variety of possible distributions for the inclination of the companion, the width of the distribution must be less than ∼20° to recreate the observations with good fidelity. As a result, the companion orbits are likely well aligned with those of the hot Jupiters, and the Kozai–Lidov mechanism does not enforce migration in these systems.
A Case for an Atmosphere on Super-Earth 55 Cancri e
Authors: Angelo Isabel , Hu Renyu 
Published: November 2017

Abstract
One of the primary questions when characterizing Earth-sized and super-Earth-sized exoplanets is whether they have a substantial atmosphere like Earth and Venus or a bare-rock surface like Mercury. Phase curves of the planets in thermal emission provide clues to this question, because a substantial atmosphere would transport heat more efficiently than a bare-rock surface. Analyzing phase-curve photometric data around secondary eclipses has previously been used to study energy transport in the atmospheres of hot Jupiters. Here we use phase curve, Spitzer time-series photometry to study the thermal emission properties of the super-Earth exoplanet 55 Cancri e. We utilize a semianalytical framework to fit a physical model to the infrared photometric data at 4.5 μm. The model uses parameters of planetary properties including Bond albedo, heat redistribution efficiency (i.e., ratio between radiative timescale and advective timescale of the atmosphere), and the atmospheric greenhouse factor. The phase curve of 55 Cancri e is dominated by thermal emission with an eastward-shifted hotspot. We determine the heat redistribution efficiency to be

, which implies that the advective timescale is on the same order as the radiative timescale. This requirement cannot be met by the bare-rock planet scenario because heat transport by currents of molten lava would be too slow. The phase curve thus favors the scenario with a substantial atmosphere. Our constraints on the heat redistribution efficiency translate to an atmospheric pressure of ∼1.4 bar. The Spitzer 4.5 μm band is thus a window into the deep atmosphere of the planet 55 Cancri e.
Know the Planet, Know the Star: Precise Stellar Densities from Kepler Transit Light Curves
Authors: Sandford Emily , Kipping David 
Published: November 2017

Abstract
The properties of a transiting planet’s host star are written in its transit light curve. The light curve can reveal the stellar density (

) and the limb-darkening profile in addition to the characteristics of the planet and its orbit. For planets with strong prior constraints on orbital eccentricity, we may measure these stellar properties directly from the light curve; this method promises to aid greatly in the characterization of transiting planet host stars targeted by the upcoming NASA Transiting Exoplanet Survey Satellite mission and any long-period, singly transiting planets discovered in the same systems. Using Bayesian inference, we fit a transit model, including a nonlinear limb-darkening law, to 66 Kepler transiting planet hosts to measure their stellar properties. We present posterior distributions of ρ
*, limb-darkening coefficients, and other system parameters for these stars. We measure densities to within 5% for the majority of our target stars, with the dominant precision-limiting factor being the signal-to-noise ratio of the transits. Of our measured stellar densities, 95% are in 3σ or better agreement with previously published literature values. We make posterior distributions for all of our target Kepler objects of interest available online at 10.5281/zenodo.1028515.

Published: November 2017

Abstract
We report the first high spectral resolution study of 17 M giants kinematically confirmed to lie within a few parsecs of the Galactic center, using

spectroscopy from Keck/NIRSPEC and a new line list for the infrared K band. We consider their luminosities and kinematics, which classify these stars as members of the older stellar population and the central cluster. We find a median metallicity of

and a large spread from approximately −0.3 to

(quartiles). We find that the highest metallicities are

, with most of the stars being at or below the solar iron abundance. The abundances and the abundance distribution strongly resemble those of the Galactic bulge rather than the disk or halo; in our small sample we find no statistical evidence for a dependence of velocity dispersion on metallicity.
High-frequency Quasi-periodic Light Variations from Arc-shaped Gas Clouds Falling onto a Black Hole
Authors: Moriyama Kotaro , Mineshige Shin , Takahashi Hiroyuki R. 
Published: November 2017

Abstract
We investigate the dynamical and radiative properties of arc-shaped gas clouds falling onto a stellar-mass black hole based on the three-dimensional general relativistic radiation-magnetohydrodynamics (3D-GRRMHD) simulation data. Assuming that the gas clouds radiate mainly due to the free–free emission and/or optically thick, inverse Compton scattering, we calculate how the emissivity distributions develop with time. We find that (1) gas clouds, each of which has a ring-like or arc shape, are intermittently formed, and that (2) they slowly fall onto the black hole, keeping nearly the Keplerian orbital velocity. These features support the dynamical properties of the gas clouds assumed in the spin measurement method proposed by Moriyama & Mineshige, but the radius of the inner edge of the accretion disk is larger than that of the marginally stable orbit (ISCO). Next, we examine how each gas cloud is observed by a distant observer by calculating the photon trajectories in the black hole spacetime. The luminosity of the accretion flow exhibits significant time variations on different timescales, reflecting the time evolution of the gas density distributions. The relatively slow variations on the time durations of 0.08–0.10 s is due to the formation and fall of gas clouds, while quasi-periodic flux peaks with short time intervals (0.01 s) are due to the quasi-periodic enhancement of light from the non-axisymmetric arc-shaped clouds through the beaming effect. This may account for the high-frequency quasi-periodic oscillations (HF QPOs) observed in black hole binaries. The observational implications and future issues are briefly discussed.
Data Reduction and Image Reconstruction Techniques for Non-redundant Masking
Authors: Sallum S. , Eisner J. 
Published: November 2017

Abstract
The technique of non-redundant masking (NRM) transforms a conventional telescope into an interferometric array. In practice, this provides a much better constrained point-spread function than a filled aperture and thus higher resolution than traditional imaging methods. Here, we describe an NRM data reduction pipeline. We discuss strategies for NRM observations regarding dithering patterns and calibrator selection. We describe relevant image calibrations and use example Large Binocular Telescope data sets to show their effects on the scatter in the Fourier measurements. We also describe the various ways to calculate Fourier quantities, and discuss different calibration strategies. We present the results of image reconstructions from simulated observations where we adjust prior images, weighting schemes, and error bar estimation. We compare two imaging algorithms and discuss implications for reconstructing images from real observations. Finally, we explore how the current state of the art compares to next-generation Extremely Large Telescopes.
