Morin-type transition in 5C pyrrhotite

We report the discovery of a low temperature spin-flop transition in 5C pyrrhotite at ~155 K that is similar to those seen in hematite at 260 K and FeS (troilite) at 440 K. The 5C crystal was produced by annealing a 4C pyrrhotite crystal at 875 K, to produce a change in the vacancy-ordering scheme that developed during cooling. The 5C structure is confirmed by single crystal x-ray diffraction and the stoichiometry and homogeneity by electron microprobe and SEM BSE mapping. RUS, heat capacity and magnetisation measurements from room temperature down to 2 K are reported. The transition is marked by a steep change in elastic properties at the transition temperature, a peak in the heat capacity and weak anomalies in measurements of magnetisation. Magnetic hysteresis loops and comparison with the magnetic properties of 4C pyrrhotite suggest that the transition involves a change in orientation of moments between two different antiferromagnetic structures, perpendicular to the crystallographic c-axis at high temperatures and parallel to the crystallographic c-axis at low temperatures. The proposed structures are consistent with a group theoretical treatment that also predicts a first order transition between the magnetic structures.Leverhulme Trus

Does Training and Support of General Practitioners in Intensive Treatment of People with Screen-Detected Diabetes Improve Medication, Morbidity and Mortality in People with Clinically-Diagnosed Diabetes? Investigation of a Spill-Over Effect in a Cluster RCT

$\textbf{Introduction}$ Very few studies have examined the potential spill-over effect of a trial intervention in general practice. We investigated whether training and support of general practitioners in the intensive treatment of people with screen-detected diabetes improved rates of redeemed medication, morbidity and mortality in people with clinically-diagnosed diabetes. $\textbf{Methods}$ This is a secondary, post-hoc, register-based analysis linked to a cluster randomised trial. In the $\textit{ADDITION-Denmark}$ trial, 175 general practices were cluster randomised (i) to routine care, or (ii) to receive training and support in intensive multifactorial treatment of individuals with screen-detected diabetes (2001 to 2009). Using national registers we identified all individuals who were diagnosed with clinically incident diabetes in the same practices over the same time period. (Patients participating in the ADDITION trial were excluded). We compared rates of redeemed medication, a cardiovascular composite endpoint, and all-cause mortality between the routine care and intensive treatment groups. $\textbf{Results}$ In total, 4,107 individuals were diagnosed with clinically incident diabetes in $\textit{ADDITION-Denmark}$ practices between 2001 and 2009 (2,051 in the routine care group and 2,056 in the intensive treatment group). There were large and significant increases in the proportion of patients redeeming cardio-protective medication in both treatment groups during follow- up. After a median of seven years of follow-up, there was no difference in the incidence of a composite cardiovascular endpoint (HR 1.15, 95% CI 0.95 to 1.38) or all-cause mortality between the two groups (HR 1.08, 95% CI 0.94 to 1.23). $\textbf{Discussion}$ There was no evidence of a spill-over effect from an intervention promoting intensive treatment of people with screen-detected diabetes to those with clinically-diagnosed diabetes. Overall, the proportion of patients redeeming cardio-protective medication during follow-up was similar in both groups. $\textbf{Trial Registration}$ ClinicalTrials.gov NCT00237549Novo Nordisk Foundation (Grant ID: NNF14OC0008981

Users acting in mixed reality interactive storytelling

“Do you expect me to talk? Oh no, Mr. Bond. I expect you to die!” Bond and Auric Goldfinger – from “Goldfinger” Abstract. Entertainment systems promise to be a significant application for Mixed Reality. Recently, a growing number of Mixed Reality applications have included interaction with synthetic characters and storytelling. However, AIbased Interactive Storytelling techniques have not yet been explored in the context of Mixed Reality. In this paper, we describe a first experiment in the adaptation of an Interactive Storytelling technique to a Mixed Reality system. After a description of the real time image processing techniques that support the creation of a hybrid environment, we introduce the storytelling technique and the specificities of user interaction in the Mixed Reality context. We illustrate these experiments by discussing examples obtained from the system.

Mahan was born in Roxbury, MA on March 3, 1899 to Francis A. and Mary (Cunningham) Mahan. He was educated at St. John’s Preparatory School in Danvers, MA. He briefly studied at Boston College before entering into the Society of Jesus on January 22, 1919 at St. Andrew-on-the-Hudson in Poughkeepsie, NY where he also spent his juniorate from 1921 until 1922. He studied Philosophy at Woodstock College, earning his A.B. in 1924 and his A.M. in 1925. He then spent his regency teaching in the Philippines from 1925 until 1928. In 1928, he returned to New England, studying Theology at Weston College until 1932 and was also ordained at Weston College in 1931. After his ordination, he taught Spanish at St.Georges College, Kingston, Jamaica and served as editor of the Catholic Opinion. In 1934, he completed his tertianship in Belgium. His next assignment was teaching English, Mathematics, Religion, and Economics at Baghdad College in Iraq in 1935. In 1957, he left for a year sabbatical at St. Francis Xavier Chapel in Boston, MA, but returned to Baghdad in 1958. During his 35 years in Iraq, he also was prefect at the boarder’s residence at the college.

Scenario planning for the Edinburgh city region

This paper examines the application of scenario planning techniques to the detailed and daunting challenge of city re-positioning when policy makers are faced with a heavy history and a complex future context. It reviews a process of scenario planning undertaken in the Edinburgh city region, exploring the scenario process and its contribution to strategies and policies for city repositioning. Strongly rooted in the recent literature on urban and regional economic development, the text outlines how key individuals and organisations involved in the process participated in far-reaching analyses of the possible future worlds in which the Edinburgh city region might find itself

Error-dependent modulation of speech-induced auditory suppression for pitch-shifted voice feedback

<p>Abstract</p> <p>Background</p> <p>The motor-driven predictions about expected sensory feedback (efference copies) have been proposed to play an important role in recognition of sensory consequences of self-produced motor actions. In the auditory system, this effect was suggested to result in suppression of sensory neural responses to self-produced voices that are predicted by the efference copies during vocal production in comparison with passive listening to the playback of the identical self-vocalizations. In the present study, event-related potentials (ERPs) were recorded in response to upward pitch shift stimuli (PSS) with five different magnitudes (0, +50, +100, +200 and +400 cents) at voice onset during active vocal production and passive listening to the playback.</p> <p>Results</p> <p>Results indicated that the suppression of the N1 component during vocal production was largest for unaltered voice feedback (PSS: 0 cents), became smaller as the magnitude of PSS increased to 200 cents, and was almost completely eliminated in response to 400 cents stimuli.</p> <p>Conclusions</p> <p>Findings of the present study suggest that the brain utilizes the motor predictions (efference copies) to determine the source of incoming stimuli and maximally suppresses the auditory responses to unaltered feedback of self-vocalizations. The reduction of suppression for 50, 100 and 200 cents and its elimination for 400 cents pitch-shifted voice auditory feedback support the idea that motor-driven suppression of voice feedback leads to distinctly different sensory neural processing of self vs. non-self vocalizations. This characteristic may enable the audio-vocal system to more effectively detect and correct for unexpected errors in the feedback of self-produced voice pitch compared with externally-generated sounds.</p

Diversity of group memberships predicts wellbeing: cross sectional and longitudinal evidence

Groups have their health and wellbeing impacts by satisfying their members’ needs and providing resources to help cope with threats. Multiple group memberships serve to accumulate these benefits and also provide resilience to the effects of group loss. However, the additional wellbeing benefits of belonging to multiple different types of group remain to be determined. In a pre-registered cross-sectional survey in Nottingham, England (Study 1, N = 328), we found that group-type diversity predicted wellbeing and that this effect was fully serially mediated by increased creative self-efficacy, then reduced loneliness. To confirm our hypothesis in a more robust sample we conducted longitudinal analyses on the English Longitudinal Study of Aging (ELSA) dataset (Study 2, N = 5,838) finding that group-type diversity at time one (T1) predicted wellbeing at T2 (4 years later), even when accounting for wellbeing and loneliness at T1. We discuss the implications for enhancing group-based health interventions

Media Representations of Breech Birth: A Prospective Analysis of Web-Based News Reports

© 2017 by the American College of Nurse-Midwives Introduction: Recent research has demonstrated that the media presentation of childbirth is highly medicalized, often portraying birth as risky and dramatic. Media representation of breech presentation and birth is unexplored in this context. This study aimed to explore the content and tone of news media reports relating to breech presentation and breech birth. Methods: Google alerts were created using the terms breech and breech birth in online English-language news sites over a 3-year period from January 1, 2013, to December 31, 2015. Alerts were received daily and filed for analysis, and data were analyzed to generate themes. Results: A total of 138 web-based news reports were gathered from 9 countries. Five themes that arose from the data included the problem of breech presentation, the high drama of vaginal breech birth, the safe option of cesarean birth versus dangers of vaginal breech birth, the defiant mother versus the saintly mother, and vaginal breech birth and medical misadventure. Discussion: Media reports in this study predominantly demonstrated negative views toward breech presentation and vaginal breech birth. Cesarean birth was portrayed as the safe option for breech birth, while vaginal breech birth was associated with poor outcomes. Media presentations may impact decision making about mode of birth for pregnant women with a breech fetus. Health care providers can play an important role in balancing the media depiction of planned vaginal breech birth by providing nonjudgmental, evidence-based information to such women to facilitate informed decision making for birth
