Eating disorders in a large clinical sample of men and women with personality disorders.

OBJECTIVE
We assessed and compared the prevalence of anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified (EDNOS) across six Axis II groups (borderline, obsessive-compulsive, avoidant, dependent, paranoid, and personality disorder NOS) and patients with major depressive disorder (MDD) without personality disorders (PD).


METHOD
The sample included 3,266 consecutive and first admissions to 16 different treatment units in the Norwegian Network of Psychotherapeutic Day Hospitals between 1993 and 2009. All patients were interviewed with the SCID-II for DSM-III-R (prior to 1996) or DSM-IV (from 1996) and the MINI for Axis I disorders in accordance with the LEAD (longitudinal, expert, all-data) standard.


RESULTS
The prevalence of any ED in the PD sample was approximately 17% for women and 3% for men. A lower rate of ED (5%) was found for patients with MDD without PD. A significantly higher proportion of patients with borderline personality disorder were diagnosed with BN or EDNOS. The rate of AN was significantly elevated in female patients with obsessive-compulsive personality disorder. Men demonstrated significantly less diagnostic co-occurrence and no significant differential variation across PD groups or MDD.


DISCUSSION
Data which included a psychiatric comparison group showed less co-occurrence and non-significant variation across PD groups for men, but demonstrated a meaningful and specific pattern of comorbidity between ED and PD for women. There was an elevated risk of ED among female patients with PD, most pronounced for borderline. An almost five-fold higher rate of AN was found among women with obsessive-compulsive PD.
A comparative analysis of the information-seeking behavior of visually impaired and sighted searchers

Understanding search behavior is important and leads to more effective interfaces that support searchers throughout the search process. In this article, through an observational user study, we investigate the search behavior of 15 visually impaired and 15 sighted searchers while they complete complex search tasks online. We study complex search tasks because they are challenging, cognitively intensive and affect performance of searchers. We compare the behavior of the two groups of searchers at four stages of the information-seeking process namely, Query Formulation, Search Results Exploration, Query Reformulation, and Search Results Management. For each stage, we identify research questions to investigate the impact of speech-based screen readers on the information-seeking behavior of visually impaired users. Significant differences were observed during query formulation and in the use of query-level support features such as query suggestions and spelling suggestions. In addition, screen-reader users submitted a lower number of queries and displayed comparatively limited exploratory behavior during search results exploration. We investigate how a lack of visual cues affected visually impaired searchers’ approach towards query reformulation and observed different strategies to manage and use information encountered during the search process. We discuss the implications that our findings have for the design of search interfaces and propose a set of design guidelines to consider when designing interfaces that are usable and accessible with screen readers. This work also enhances our understanding of search behavior when using an auditory interface and could be useful when designing audio-based information retrieval systems.
76GHz CMOS Voltage-Controlled Oscillator with 7% Frequency Tuning Range

To improve the tuning range and phase noise in W-band CMOS voltage-controlled oscillators (VCOs), we propose a new ring-shaped transmission line for the LC tank. As a result, a VCO with a 76.5 GHz center frequency, a tuning range of 7% and a phase noise of -110.6 dBc/Hz was realized by using a 90 nm CMOS 1P6M process.
Grain-128a: a new version of Grain-128 with optional authentication

A new version of the stream cipher Grain-128 is proposed. The new version, Grain-128a, is strengthened against all known attacks and observations on the original Grain-128, and has built-in support for optional authentication. The changes are modest, keeping the basic structure of Grain-128. This gives a high confidence in Grain-128a and allows for easy updating of existing implementations.

“Fitspiration” on Social Media: A Content Analysis of Gendered Images

BACKGROUND
"Fitspiration" (also known as "fitspo") aims to inspire individuals to exercise and be healthy, but emerging research indicates exposure can negatively impact female body image. Fitspiration is frequently accessed on social media; however, it is currently unclear the degree to which messages about body image and exercise differ by gender of the subject.


OBJECTIVE
The aim of our study was to conduct a content analysis to identify the characteristics of fitspiration content posted across social media and whether this differs according to subject gender.


METHODS
Content tagged with #fitspo across Instagram, Facebook, Twitter, and Tumblr was extracted over a composite 30-minute period. All posts were analyzed by 2 independent coders according to a codebook.


RESULTS
Of the 415/476 (87.2%) relevant posts extracted, most posts were on Instagram (360/415, 86.8%). Most posts (308/415, 74.2%) related thematically to exercise, and 81/415 (19.6%) related thematically to food. In total, 151 (36.4%) posts depicted only female subjects and 114/415 (27.5%) depicted only male subjects. Female subjects were typically thin but toned; male subjects were often muscular or hypermuscular. Within the images, female subjects were significantly more likely to be aged under 25 years (P<.001) than the male subjects, to have their full body visible (P=.001), and to have their buttocks emphasized (P<.001). Male subjects were more likely to have their face visible in the post (P=.005) than the female subjects. Female subjects were more likely to be sexualized than the male subjects (P=.002).


CONCLUSIONS
Female #fitspo subjects typically adhered to the thin or athletic ideal, and male subjects typically adhered to the muscular ideal. Future research and interventional efforts should consider the potential objectifying messages in fitspiration, as it relates to both female and male body image.
10-W/mm AlGaN-GaN HFET with a field modulating plate

AlGaN-GaN heterojunction field-effect transistors (HFETs) with a field modulating plate (FP) were fabricated on an SiC substrate. The gate-drain breakdown voltage (BV/sub gd/) was significantly improved by employing an FP electrode, and the highest BV/sub gd/ of 160 V was obtained with an FP length (L/sub FP/) of 1 /spl mu/m. The maximum drain current achieved was 750 mA/mm, together with negligibly small current collapse. A 1-mm-wide FP-FET (L/sub FP/=1 /spl mu/m) biased at a drain voltage of 65 V demonstrated a continuous wave saturated output power of 10.3 W with a linear gain of 18.0 dB and a power-added efficiency of 47.3% at 2 GHz. To our knowledge, the power density of 10.3 W/mm is the highest ever achieved for any FET of the same gate size.
Forecasting prices from level-I quotes in the presence of hidden liquidity

Bid and ask sizes at the top of the order book provide information on short-term price moves. Drawing from classical descriptions of the order book in terms of queues and order-arrival rates (Smith et al., 2003), we consider a diffusion model for the evolution of the best bid/ask queues. We compute the probability that the next price move is upward, conditional on the best bid/ask sizes, the hidden liquidity in the market and the correlation between changes in the bid/ask sizes. The model can be useful, among other things, to rank trading venues in terms of the “information content” of their quotes and to estimate hidden liquidity in a market based on high-frequency data. We illustrate the approach with an empirical study of a few stocks using quotes from various exchanges.
Blockchain - From the Anarchy of Cryptocurrencies to the Enterprise (Keynote Abstract)

A blockchain is a public ledger for recording transactions, maintained by many nodes without central authority through a distributed cryptographic protocol. All nodes validate the information to be appended to the blockchain, and a consensus protocol ensures that the nodes agree on a unique order in which entries are appended. Distributed protocols tolerating faults and adversarial attacks, coupled with cryptographic tools are needed for this. The recent interest in blockchains has revived research on consensus protocols, ranging from the proof-of-work method in Bitcoin’s “mining” protocol to classical Byzantine agreement. Going far beyond its use in cryptocurrencies, blockchain is today viewed as a promising technology to simplify trusted exchanges of data and goods among companies. In this context, the Hyperledger Project has been established in early 2016 as an industry-wide collaborative effort to develop an open-source blockchain. This talk will present an overview of blockchain concepts, cryptographic building blocks and consensus mechanisms. It will also introduce Hyperledger Fabric, an implementation of blockchain technology intended for enterprise applications. Being one of the key partners in the Hyperledger Project, IBM is actively involved in the development of this blockchain platform. 1998 ACM Subject Classification C.2.4 Distributed Systems
The Effectiveness and Cost‐Effectiveness of Spinal Cord Stimulation for Refractory Angina (RASCAL Study): A Pilot Randomized Controlled Trial

BACKGROUND
Patients with "refractory angina" (RA) unsuitable for coronary revascularization experience high levels of hospitalization and poor health-related quality of life. Randomized trials have shown spinal cord stimulation (SCS) to be a promising treatment for chronic stable angina and RA; however, none has compared SCS with usual care (UC). The aim of this pilot study was to address the key uncertainties of conducting a definitive multicenter trial to assess the clinical and cost-effectiveness of SCS in RA patients, i.e., recruitment and retention of patients, burden of outcome measures, our ability to standardize UC in a UK NHS setting.


METHODS
RA patients deemed suitable were randomized in a 1:1 ratio to SCS plus UC (SCS group) or UC alone (UC group). We sought to assess: recruitment, uptake, and retention of patients; feasibility and acceptability of SCS treatment; the feasibility and acceptability of standardizing UC; and the feasibility and acceptability of the proposed trial outcome measures. Patient outcomes were assessed at baseline (prerandomization) and three and six months postrandomization.


RESULTS
We failed to meet our planned recruitment target (45 patients) and randomized 29 patients (15 SCS group, 14 UC group) over a 42-month period across four sites. None of the study participants chose to withdraw following consent and randomization. With exception of two deaths, all completed evaluation at baseline and follow-up. Although the study was not formally powered to compare outcomes between groups, we saw a trend toward larger improvements in both primary and secondary outcomes in the SCS group.


CONCLUSIONS
While patient recruitment was found to be challenging, levels of participant retention, outcome completion, and acceptability of SCS therapy were high. A number of lessons are presented in order to take forward a future definitive pragmatic randomized trial.
The roles of individual and organizational factors in burnout among community-based mental health service providers.

Public-sector mental health care providers are at high risk for burnout, which negatively affects not only provider well-being but also the quality of services for clients and the functioning of organizations. This study examines the influence of demographics, work characteristic, and organizational variables on levels of burnout among child and adolescent mental health service providers operating within a public-sector mental health service system. Additionally, given the dearth of research examining differences in burnout levels among mental health subdisciplines (e.g., social work, psychology, marital and family therapy) and mental health programs (e.g., outpatient, day treatment, wraparound, case management), analyses were conducted to compare levels of burnout among multiple mental health disciplines and program types. Surveys were completed by 285 providers across 49 mental health programs in a large urban public mental health system. Variables representing dimensions of organizational climate and transformational leadership accounted for the greatest amount of variance in provider reported burnout. Analyses demonstrated significantly lower levels of depersonalization among wraparound providers compared to traditional case managers. Age was the only demographic variable related to burnout. Additionally, no significant effects were found for provider discipline or for agency tenure and caseload size. Results suggest the need to consider organizational development strategies aimed at creating more functional and less stressful climates and increasing levels of transformational leadership behaviors in order to reduce levels of burnout among clinicians working in public mental health settings for youth and families.
Peri-implantitis: from diagnosis to therapeutics.

Peri-implantitis is an infection of the tissue around an implant, resulting in the loss of supporting bone. Risk factors for peri-implantitis consist of a history of periodontitis, dental plaque, poor oral hygiene, smoking, alcohol consumption and diabetes. A clinical diagnosis indicates inflammatory signs including bleeding on probing with or without suppuration and a peri-implant pocket depth ≥5 mm. A radiograph shows images of marginal bone loss ≥2 mm. A differential diagnosis of peri-implant mucositis, occlusal overload, retrograde peri-implantitis and inflammatory implant periapical lesions suggests the appropriate treatment in each case. The non-surgical treatment of peri-implantitis, including a mechanical treatment alone or combined with antiseptics or antibiotics can improve clinical parameters in the short term but residual defects may still persist. Surgical treatment such as guided bone regeneration results in a gain of clinical attachment level and bone reconstruction in the long term. The limited effect of laser-assisted therapy needs to be further evaluated. The concept of prevention based on early detection and regular maintenance plays a principal role in reducing the occurrence of peri-implantitis.
The Stroke Oxygen Study (SO2S) - a multi-center, study to assess whether routine oxygen treatment in the first 72 hours after a stroke improves long-term outcome: study protocol for a randomized controlled trial

BACKGROUND
Mild hypoxia is common in stroke patients and may have significant adverse effects on the ischemic brain after stroke. The use of oxygen treatment is rapidly increasing in European stroke units but is not without side effects. It impedes early mobilization, could pose an infection risk, and may encourage the formation of toxic free radicals, leading to further damage to the ischemic brain. In the Stroke Oxygen Pilot Study (2 or 3 L/min for 72 hours) neurological recovery at one week was better in the oxygen group than in controls, and after correction for difference in baseline stroke severity and prognostic factors, there was a trend to better outcome with oxygen at six months. Oxygen was as effective in mild as in severe strokes.Oxygen saturation is lower at night than during the day, and episodes of oxygen desaturation are common during sleep. Nocturnal oxygen supplementation is likely to reduce the burden of hypoxia without interfering with daytime mobilization and rehabilitation.Before wider use of oxygen supplementation becomes established it is important to obtain better evidence on which patients benefit from such treatment.


METHODS
Participants will be randomized to one of three groups: the first will receive continuous oxygen for 72 hours (at a rate of 2 or 3 L/min depending on baseline oxygen saturation), the second group will receive nocturnal oxygen only (at a rate of 2 or 3 L/min depending on baseline oxygen saturation) and the third group will not receive any oxygen (control). A baseline assessment is performed at randomization and a one-week follow-up completed. Outcome data at three, six and twelve months will be obtained via a questionnaire sent to the patient by the trial center.


DISCUSSION
This study will provide evidence on the effectiveness of oxygen supplementation for the treatment of stroke and whether nocturnal oxygen is a potentially beneficial therapy regimen.


TRIAL REGISTRATION
This trial is registered with the ISRCTN register ID number ISRCTN52416964.
A geometric view of parametric linear programming

We present a new definition of optimality intervals for the parametric right-hand side linear programming (parametric RHS LP) Problem ϑ(λ) = min{c t x¦Ax =b + λ¯b,x ≥ 0}. We then show that an optimality interval consists either of a breakpoint or the open interval between two consecutive breakpoints of the continuous piecewise linear convex function ϑ(λ). As a consequence, the optimality intervals form a partition of the closed interval {λ; ¦ϑ(λ)¦ < ∞}. Based on these optimality intervals, we also introduce an algorithm for solving the parametric RHS LP problem which requires an LP solver as a subroutine. If a polynomial-time LP solver is used to implement this subroutine, we obtain a substantial improvement on the complexity of those parametric RHS LP instances which exhibit degeneracy. When the number of breakpoints of ϑ(λ) is polynomial in terms of the size of the parametric problem, we show that the latter can be solved in polynomial time.
Modeling and parameter estimation for the clutch driven disc detection system

In this paper, a method of estimating the parameters of the model of the clutch driven disc detection system is proposed. After analyzing the parts of the clutch driven disc detection system, the simplified mathematical model is built. The model parameters were estimated by the Least Squares method. Based on the virtual instrument technology of NI company, the interface and data acquisition programs are developed. The simulation results and the experiments show that the characteristics of the identified model are similar to the characteristics of the open loop control system and the calculating speed is improved by using the complex method.
Investigation of formic acid oxidation on palladium in acidic solutions by on-line mass spectroscopy

Abstract A new insight into the electrochemical oxidation of formic acid on palladium is presented. On-line mass spectroscopy analysis of volatile products reveals the production of carbon dioxide not only in the double-layer region but also near 0.25 and 1.75 V. At these potentials the currents are masked by hydrogen oxidation and oxygen evolution, respectively, and the reaction has not been investigated so far. The presence of strongly adsorbed residues at small coverages is proved by on-line mass spectroscopy.

CENTRAL PROBLEMS IN THE MANAGEMENT OF INNOVATION *

Innovation is defined as the development and implementation of new ^^eas by people who over time engage in transactions with others within an institutional order. Thxs defmUion focuses on four basic factors (new ideas, people, transactions, and ms itut.onal context)^An understanding of how these factors are related leads to four basic problems confronting most general managers: (1) a human problem of managing attention, (2) a process probleni in manlgng new ideas into good currency, (3) a structural problem of managing part-whole TelatLnships, and (4) a strategic problem of institutional leadership. This paper discusses thes four basic problems and concludes by suggesting how they fit together into an overall framework to guide longitudinal study of the management of innovation.

Deterring Delinquents: A Rational Choice Model of Theft and Violence

siderably in the social sciences, particularly in economics, political science, and law (e.g., Morrow 1994; Posner 1998; Sunstein 1999). In sociology, especially with the popularity of social capital theory, rational choice has gained traction as an individual-level theory of motivation compatible with macro-level theories of social structure (Coleman 1990). Nevertheless, skepticism in sociology persists, in part due to misconceptions, but more importantly due to questions about the explanatory power of rational choice theories. Proponents and skeptics alike agree that a fair assessment of the theory asks whether it has paid off empirically. Hechter and Kanazawa (1997) conclude that some empirical studies support rational explanations (sometimes unwittingly) in areas beyond market behavior, but that additional research is needed to examine rational choice theory in a variety of areas of social life and forms of social action. A challenging and important empirical puzzle for rational choice theory concerns the social control of criminal behavior. Crime is a difficult case for rational choice theory. In the case of street crime, behavior is typically characterized as irrational and suboptimal. This is in contrast to market behavior, financial decisions, and corporate crime, where institutionalized norms frame decision making in the terms of rationality or optimality. Indeed, the media—and some academics—commonly portray street criminals as impulsive, unthinking, Deterring Delinquents: A Rational Choice Model of Theft and Violence
An up to 3-year randomized clinical study comparing indirect and direct resin composites used to restore worn posterior teeth.

PURPOSE
To compare a developmental indirect resin composite with an established, microfilled directly placed resin composite used to restore severely worn teeth. The cause of the tooth wear was a combination of erosion and attrition.


MATERIALS AND METHODS
Over a 3-year period, a total of 32 paired direct or indirect microfilled resin composite restorations were placed on premolars and molars in 16 patients (mean age: 43 years, range: 25 to 62) with severe tooth wear. A further 26 pairs of resin composite were placed in 13 controls (mean age: 39 years, range 28 to 65) without evidence of tooth wear. The material was randomly selected for placement in the left or right sides of the mouth.


RESULTS
Sixteen restorations were retained in the tooth wear group (7 indirect and 9 direct), 7 (22%) fractured (4 indirect and 3 direct), and 9 (28%) were completely lost (5 indirect and 4 direct). There was no statistically significant difference in failure rates between the materials in this group. The control group had 21 restorations (80%) that were retained (10 indirect and 12 direct), a significantly lower rate of failure than in the tooth wear patients (P = .027).


CONCLUSION
The results of this short-term study suggest that the use of direct and indirect resin composites for restoring worn posterior teeth is contraindicated.
