Truly Enthralling: Epileptiform Events In Film and On Television—Why They Persist and What We Can Do About Them

ABSTRACT Seizures and epilepsy have been portrayed in film since 1900 and on television since the 1950s, but unlike many other conditions, their depictions have not improved with increased scientific understanding. At this time, most individuals who are under 45 years of age will never witness a seizure. Thus, their information about what seizures are comes from depictions in film and on television. Because especially on television these fictive and often erroneous images are increasing, many think of them as accurate. The research addresses three questions in relation to these images: How do directors use the images? Why do uses of seizures in visual media not reflect contemporary scientific knowledge? Why have they persisted and increased in use? Data consist of material from 242 films and television episodes. The general category of seizures includes seizures in characters said to have epilepsy or some other condition, seizures related to alcohol/drug use, feigned or pseudoseizures, and a “throwaway” category. The research demonstrates how epileptiform events drive the narrative, support the genre, evoke emotional reactions, highlight traits of characters with seizures, accentuate traits of other characters through their responses, act as catalysts for action, and enhance voyeuristic experience. Through connecting categories, we explain a basic social process (Glaser, 2007). The conclusion is that these images are so enthralling that their use is likely to persist. The authors suggest that advocates acknowledge this and then find ways to have more continuing characters with correctly depicted epilepsy be part of television series as a way of exploring the truly enthralling dimensions of the condition.
Synchronization analysis of complex delayed dynamical networks consisting of Lur'e systems

The paper is concerned with the problem of global synchronization for a class of dynamical complex network composed of general Lur'e systems, the network model can represent both the directed and undirected weighted networks. Based on the Lyapunov stability theory and property of the coupling matrix, the delay-independent decentralized nonlinear feedback controllers are designed to globally synchronize the network under the assumption that coupling coefficients are known. When coupling coefficients are unavailable, the delay-independent decentralized adaptive controllers are introduced to guarantee the global synchronization of the uncertain network. Two examples are given to demonstrate the effectiveness of proposed results.
Return Windows and the Value Relevance of Earnings

Research on the value relevance of annual earnings commonly accumulate stock returns over a 12-month period starting from the fourth month of the fiscal year, resulting in a mismatch between the return window and the earnings period (i.e. the fiscal year). By comparing this return window with alternative windows, we show that the mismatch produces a downward bias in the estimated R from the regression of stock returns on earnings, especially for firms that announce earnings early. Our results also show that both profits and losses are more value relevant when announced earlier, supporting regulatory calls for timely disclosure. Accounting and Finance
Head-Mounted Display for Diving Computer Platform

Dive Computers are usually integrated in a console or wrist worn. They display dive relevant data such as depth, time and decompression obligations. Continuous monitoring of these data is of the utmost importance for safety when diving. This paper describes a light weight, 300 m water resistant, graphical head-mounted matrix display (HMD), which is connected to a wrist worn diving computer and that gives an exact copy of the diving computer screen. Optical components are included to display a virtual image from a distance of 1.0 m. The monocular HMD only occludes a small peripheral area of the divers field of view thus causes relatively little optical interference. The unique design, which enables attachment to almost any diving mask on the market, furthermore allows outstanding pressure resistance and at the same time cost effective manufacturing.
A haptic device DELTA-4: Kinematics and its analysis

In this paper, a new parallel link mechanism “DELTA-4” is developed as a new haptic device within a high quality force display capability and operability. DELTA-4 realizes 3 DOF of translational motions by a new redundant parallel link mechanism. The name of the mechanism DELTA-4 is derived from a conventional parallel link mechanism “DELTA”, because there are several common points on motion constraints of end-effector. However, these benefits can be obtained by DELTA-4: wider working area, smaller footprint, better mechanical access of end-effector from operators.
Prospective study of the efficacy of breast magnetic resonance imaging and mammographic screening in survivors of Hodgkin lymphoma.

PURPOSE Current guidelines recommend breast magnetic resonance imaging (MRI) as an adjunct to mammography for breast cancer screening in female cancer survivors treated with chest irradiation at a young age, beginning 8 to 10 years after treatment. Prospective data evaluating its efficacy in female cancer survivors are lacking. This study sought to compare the sensitivity and specificity of breast MRI with those of mammography in women who received chest irradiation for Hodgkin lymphoma (HL). PATIENTS AND METHODS We enrolled 148 women treated with chest irradiation for HL at age ≤ 35 years who were > 8 years beyond treatment. Yearly breast MRI and mammogram were performed over a 3-year period. Sensitivity and specificity of the two screening modalities were compared. RESULTS With the screening, 63 biopsies were performed in 45 women; 18 (29%) showed a malignancy. All but one of the screen-detected malignancies were preinvasive or subcentimeter node-negative breast cancers. After excluding first-screen MRI and mammogram, mammogram sensitivity was 68% as compared with 67% for MRI (P = 1.0). Sensitivity increased to 94% using both screening modalities. The specificities of mammogram alone, MRI alone, and both were 93%, 94%, and 90%, respectively. CONCLUSION In contrast to women with genetic or familial risk, in HL survivors breast MRI was not more sensitive than mammogram for breast cancer detection. However, the two screening modalities complement each other in the detection of early cases of disease. Early diagnosis is particularly important in these patients, given the breast cancer treatment challenges in patients who have received prior cancer therapy.
Evolving a blueprint for certification: the responsibilities and knowledge comprising American professional oncology nursing practice.

Ensuring adequate content validity of a certification examination is a major concern in the development and administration of a test. To establish content validity of the Oncology Nursing Certification Corporation (ONCC) certification exam, a job analysis study was conducted to provide empirical data about the responsibilities and knowledge areas required for practice at the level of the newly certified oncology nurse. The study involved The Profession of Oncology Nursing: An Inventory of Responsibilities and Knowledge (IRKPON), a questionnaire that was developed based on a review of the literature, professional practice information, interviews with oncology nurses, the original ONCC certification exam table of specifications, and evaluations undertaken by two advisory committees. The IRKPON consisted of three parts: 56 responsibilities clustered into eight job dimensions, 217 knowledge areas grouped into seven knowledge dimensions, and demographic information. The IRKPON was sent to a stratified random sample of 3,000 oncology nurses in the United States, who were asked to rate both the responsibilities and knowledge areas by level of importance. The 1,297 (43%) responding nurses rated 45 of 56 responsibilities (80.4%) as "very important" and 8 of 56 responsibilities (14.3%) as "extremely important"; they also rated 163 of 217 knowledge areas (75.1%) as "very important" and 41 of 217 knowledge areas (18.9%) as "extremely important. " These findings identified the specific responsibilities most important to the oncology nurse role at the level of the newly certified nurse, as well as the knowledge areas necessary for competent performance. Subsequent ONCC certification examinations were modified; the test blueprint that guides the construction of the examination was revised, and the passing score was adjusted.
Vagus nerve stimulation reverses ventricular electrophysiological changes induced by hypersympathetic nerve activity.

Vagus nerve stimulation (VNS) has shown therapeutic potential for myocardial infarction-induced ventricular arrhythmias. This study aimed to investigate the effects of VNS on ventricular electrophysiological changes induced by hypersympathetic nerve activity. Seventeen open-chest dogs were subjected to left stellate ganglion stimulation (LSGS) for 4 h to simulate hypersympathetic tone. All animals were randomly assigned to the VNS group (n = 9) or the control group (n = 8). In the VNS group, VNS was performed at the voltage causing a 10% decrease in heart rate for hours 3-4 during 4 h of LSGS. During the first 2 h of LSGS, the ventricular effective refractory period (ERP) and action potential duration (APD) were both progressively and significantly decreased; the spatial dispersion of ERP, maximal slope of the restitution curve and pacing cycle length of APD alternans were all increased. With LSGS + VNS during the next 2 h, there was a significant return of all the altered electrophysiological parameters towards baseline levels. In the eight control dogs that received 4 h of LSGS without VNS, all the parameters changed progressively, but without any reversals. The ventricular fibrillation threshold was higher in the VNS group than in the control group (17.3 ± 3.4 versus 11.3 ± 3.8 V, P < 0.05). The present study demonstrated that VNS was able to reverse LSGS-induced ventricular electrophysiological changes and suppress the occurrence of ventricular fibrillation.
Phasor-Domain Modeling of Resonant Inverters for High-Frequency AC Power Distribution Systems

The circuit modeling and analysis of resonant inverters is complex because the state variables such as inductor currents and capacitor voltages are AC dominant. The phasor dynamic modeling method maps the periodical time-varying state variables into stationary frame for each harmonic of interest. Correspondingly, the circuit is decomposed into two DC subcircuits, the state variables of which are the time-varying Fourier coefficients of the original AC variables. A small-signal model can be derived by applying small perturbation and linearization to the Fourier coefficients. A phasor-domain modeling method is used to investigate the resonant inverters in high-frequency AC power distribution systems. A resonant inverter system with five energy storage elements is modeled and simulated, and compared with switch simulation for both steady state and transients. The phasor model simulation matches the switch model simulation in both steady state and transients, but takes much less computing time. In addition, this model closely relates to the power converter topology in time domain, and therefore, keeps the physical meaning of the state variables. It can be used for high accuracy of modeling, simulation, and circuit analysis and control design. It can be extended to a higher order of resonant topologies including parasitic components. A high-frequency AC system with two pulse-phase-modulation-controlled resonant inverters is modeled and simulated, and the current distribution control is investigated with the phasor model. The model simulation is compared with switch-level simulation and experimental results.
Degradation Feature Selection for Remaining Useful Life Prediction of Rolling Element Bearings

Rolling element bearings are among the most widely used and also vulnerable components in rotating machinery equipment. Recently, prognostics and health management of rolling element bearings is more and more attractive both in academics and industry. However, many studies have been focusing on the prognostic aspect of bearing prognostics and health management and few efforts have been performed in relation to the optimal degradation feature selection issue. For more effective and efficient remaining useful life predictions, three goodness metrics of correlation, monotonicity and robustness are defined and combined for automatically more relevant degradation feature selection in this paper. Effectiveness of the proposed method is verified by rolling element bearing degradation experiments. Copyright © 2015 John Wiley & Sons, Ltd.
Higher muscle protein synthesis in women than men across the lifespan, and failure of androgen administration to amend age‐related decrements

We investigated age and sex effects and determined whether androgen replacement in elderly individuals (≥60 yr) could augment protein synthesis. Thirty young men and 32 young women (18‐31 yr) were studied once, whereas 87 elderly men were studied before and after 1 yr of treatment with 5 mg/day testosterone (T), 75 mg/day dehydroepiandrosterone (DHEA), or placebo (P);and 57 elderly women were studied before and after 1 yr of treatment with 50 mg/day DHEA or P. [15N]Phenylalanine and [2H4]tyrosine tracers were infused, with measurements in plasma and vastus lateralis muscle. Whole‐body protein synthesis per fat‐free mass and muscle protein fractional synthesis rate (FSR) were lower in elderly than in young individuals (P< 0.001), not significantly affected by hormone treatments, and higher in women than in men (P<0.0001), with no sex × age interaction. In regression analyses, peak O2 consumption (VO2peak), resting energy expenditure (REE), and sex were independently associated with muscle FSR, as were VO2peak, REE, and interactions of sex with insulin‐like growth factor‐II and insulin for whole‐body protein synthesis. Women maintain higher protein synthesis than men across the lifespan as rates decline in both sexes, and neither full replacement of DHEA (in elderly men and women) nor partial replacement of bioavailable T (in elderly men) is able to amend the age‐related declines. — Henderson, G.

A Propensity Score Matching Analysis of the Effects of Special Education Services

We sought to quantify the effectiveness of special education services as naturally delivered in U.S. schools. Specifically, we examined whether children receiving special education services displayed (a) greater reading or mathematics skills, (b) more frequent learning-related behaviors, or (c) less frequent externalizing or internalizing problem behaviors than closely matched peers not receiving such services. To do so, we used propensity score matching techniques to analyze data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998—99, a large-scale, nationally representative sample of U.S. schoolchildren. Collectively, results indicate that receipt of special education services has either a negative or a statistically nonsignificant impact on children’s learning and behavior. However, special education services do yield a small, positive effect on children’s learning-related behaviors.
The Value of Bayes Theorem in the Interpretation of Subjective Diagnostic Findings: What Can We Learn from Agreement Studies?

The Bayes theorem is advocated as the appropriate measure for the Weight of evidence in medical decision making. It is based on the calculation of posttest probability as a function of the accuracy of the test and pretest probability. Nevertheless, for subjective diagnostic findings, there might be substantial variability in the accuracy among human observers, making the point estimate of posttest probability imprecise. Although there is limited evidence regarding the actual variability of accuracy among observers for the majority of diagnostic findings, classical observer agreement studies provide us With an indirect estimate of such variability. The aim of this Work Was to explicate the relationship betWeen observer disagreement and variability of posttest probability. Using a random effects signal detection model With 3 stochastic components (betWeen subject, betWeen observer, and residual variations), the authors modeled diagnostic tests With various characteristics and calculated the expected betWeen-observer disagreement and 95% interval of the observers' posttest probability. For the majority of simulated conditions, variation in posttest probability Was surprisingly high, even in the presence of substantial agreement. Although the model is based on parametric assumptions, these results are a clue to a source of inaccuracy in the calculation of posttest probability. Practitioners should be aWare of such variation in their clinical practice, and diagnostic studies need to develop strategies to address this uncertainty.
Modelo LDA para medición avanzada de riesgo operacional

This paper presents the simulated results after the application of an operational risk measurement model, and the benefits obtained when an adequate process is followed to identify risk-generating sources. This serves as support to the control stage through the monitoring of indicators to mitigate operational risks. The main approach of this study lies on one of the advanced operational risk measurement models suggested by Basilea, specifically the loss distribution approach (lda), applied to three types of operational risk events in one of the business lines of a financial institution in Colombia. Operational Value-at-Risk (OpVaR) quantification was made under two comparison methods, and determined by the characteristics of distributions in the calculation of expected and unexpected losses for each event. Results show an estimate of the range of values that may be the point of reference for the organization in order to maintain a required economic capital that covers future exposures to operational risk.

The value of the equivalent unloaded Q of the resonant element exceeds 37,000 in our experiment.
Institutional Factors and Processes in Interagency Collaboration: The Case of FEMA Corps

This article details the development and implementation of the Federal Emergency Management Agency (FEMA) Corps program, a federal interagency partnership. While many federal agencies partner through fee-for-service arrangements and contracts, few contemporary examples of interagency program creation and implementation are available. This article develops an interagency collaboration framework by drawing from the collaboration literature, as well as literature on institutions, to examine the development of this unique partnership. This research draws on key informant interviews and content analysis of documentation, including the interagency agreement (IAA), historical records, memos, meeting minutes, and participant observations. Findings suggest that even in formal IAAs, a strong history of informal institutional collaboration may be an important antecedent of forming and implementing collaborative arrangements. Similarly, the presence of a champion may play an important role in cultivating and developing both informal and formal institutions that create an opportunity to collaborate. Finally, the rules-in-use and the rules-in-form may vary at different levels of management. As the federal government increasingly employs interagency partnerships, this article provides lessons for developing relationships, identifying and understanding roles, crossing organizational boundaries, and merging both agency cultures and administrative processes.
Social service systems for vulnerable children and families in low‐ and middle‐income countries: Establishing definitions and key components

Systems strengthening in low‐ and middle‐income countries has long been a topic of concern in global health. By comparison, until very recently, little attention has been paid to the importance of strengthening social service systems to provide a holistic perspective of children's and families' multifaceted strengths and vulnerabilities. This study has reviewed existing literature on the definitions and components of social service systems and provides an analysis of data from key informants in the field of global social welfare. Based on this information, a set of key components is presented and compared, derived from the literature and expert interviews. Existing challenges for the field include establishing consensus on terminology and critical components, implementing and documenting critical components, and linking these components to client outcomes.
Radiofrequency catheter ablation for the treatment of supraventricular tachycardias in children and adolescents

Abstract We report our experience in radiofrequency catheter ablation between April, 1992 and December, 1998, in which we treated 287 parients less than 18 years of age (mean 14.3±3.1 years) with supraventricular tachycardia. Accessory pathways were the arrhythmic substrate in 252 of the patients (87.8%), the patients having a total of 265 accessory pathways. Atrioventricular nodal re-entry was the cause of tachycardia in 26 patients (9.0%), while atrial flutter was detected in the remaining 9 patients (3.1%). We were able successfully to eliminate the accessory pathway in 236 patients (89%), but 25 patients had recurrent arrhythmias. Ablation proved successful in all cases of atrioventricular node re-entry tachycardia, the slow pathway being ablated in 25 patients, and the fast pathway in only one case. Recurrence of the arrhythmia occurred in three patients (11.5%). We performed a second ablation in these children, all then proving successful. The ablation was successful in all cases of atrial flutter, with one recurrence (11.1%). Overall, therefore, ablation was immediately successful in 271 patients (94.4%), with a recurrence of the arrhythmia in 29 cases (10.7%). The incidence of serious complications was 2.09% There was one late death due to infective endocarditis, 3 patients suffered complete heart block, 1 had mild mitral regurgitation, and 1 patient developed an haematoma in the groin. We conclude that radiofrequency catheter ablation can now be considered a standard option for the management of paroxysmal supraventricular tachycardias in children and young adults.
