Comparison of continuity in a resident versus private practice.

BACKGROUND There is widespread agreement among pediatric educators that continuity (following a panel of patients on a first contact basis for all their health care) is an important part of the education of pediatricians. OBJECTIVE To measure continuity in a pediatric residency practice and to compare this continuity with 2 nearby private general pediatric group practices. We also examined measures of continuity suggested in the literature. DESIGN Visit data were obtained from the practice billing system for a resident continuity practice and 2 nearby private practices for the 3-year period from July 1, 1992, to June 30, 1995. Visit data used were restricted to patients seen in the office of the practices during regular office hours. Continuity was measured using 5 different indices: 1) the usual provider of care index, visits by the usual clinician/total visits, 2) continuity for patient, the average proportion of visits that an individual patient was seen by his or her own physician, 3) continuity for physician (PHY), the average proportion of visits that an individual physician saw his or her own patients, 4) Continuity of Care Index (COC), and 5) the Modified, Modified Continuity Index. During the period examined, pediatric residents were present in the continuity practice for 1 half-day each week. The resident continuity practice (RCP) had 57 residents and saw 3386 patients for 18 955 visits. Private practice 1 (PP1) had 4 pediatricians who saw 4968 patients for 33 537 visits. Private practice 2 (PP2) had 5 pediatricians who saw 11 953 patients for 75 778 visits. RESULTS For all visit types, continuity in the RCP was not as high as in the private practices, PHY-RCP versus PP1, PP2; 53% versus 70%, 77%. However, continuity in RCP was greater than 50% for all measures except the COC index, which precipitously decreases as the number of clinicians seen increases. Examining continuity for health maintenance visits (PHY-RCP, PP2 vs PP1; 96%, 96% vs 82%) RCP was equal to the best of the private practices. The percentage of patients not seen for a health maintenance visit during the study period was lowest in the resident practice (RCP/PP1/PP2, 15/22/30). CONCLUSIONS Although continuity for all visits in this RCP was less than in private practice, it was surprisingly high, considering the limited time residents spend in clinic. In a particularly important area for continuity, health maintenance visits, continuity was identical to one and superior to the other private practice.
SIP Extensions for Instant Messaging

The main charge of a flare is delayed from being ignited, due to hot gases directed toward a surface of said main charge, by a member covering said surface. The covering member defines a plurality of flare outlet openings communicating with a gap formed between said covering member and said flare surface, and also defines a cavity containing a priming charge, or a priming charge and a delayed charge, exposed for ignition by said hot gases and operative, after a time delay, to ignite the flare over a large surface area via said gap. A further member temporarily covers said plurality of flare outlet openings, said further member being removed to expose said outlet openings upon sudden deceleration of the flare, or due to hot gases produced by ignition of said flare surface.
DNA Adduct Assessment During Antihormonal Treatment of Perianal Gland Tumors With Tamoxifen in Male Dogs

Background/Aim: Determination of DNA adduct count was performed in mononuclear cells during antihormonal treatment of perianal gland tumors. Materials and Methods: Eight- to fifteen-year-old dogs with carcinoma (CAR Group; N=5), epithelioma (EPI Group; N=16) or adenoma (ADE Group; N=24) were used. The control group suffered from perineal hernia or rectal diverticulum (CTR Group; N=25). Blood was collected at baseline, and at one and six months after the beginning of the anti-hormonal treatment with tamoxifen (1 mg/kg of body weight). DNA adduct count was determined using autoradiography. Results: At baseline, DNA adduct count reached the highest value in the CTR Group, and the lowest in the EPI Group (p<0.05). Six-month-long therapy with tamoxifen resulted in a significant increase in the DNA adduct count by 78.7%, 221.5% and 198.3% in the ADE, EPI and CAR groups, respectively (p<0.05). Conclusion: Increased DNA adduct formation after long-term administration of tamoxifen shows its genotoxicity.
On the Link Between External Forcings and Slope Instabilities in the Piton de la Fournaise Summit Crater, Reunion Island

We have analyzed the impact of different forcings, such as rain and seismicity, on slope instabilites on an active volcano. For this, we compiled a catalog of the locations and volumes of rockfalls in the Piton de la Fournaise crater using seismic records. We validated it by comparing the locations and volumes to those deduced from photogrammetric data. We analyzed 10,477 rockfalls, spanning the period 2014 to 2016. This period corresponds to the renewal of volcanic activity after a 41‐month rest. Our analysis reveals that renewed eruptive activity has unsettled the crater edges. External forcings such as rain and seismicity are shown to potentially increase the number and the volume of rockfalls, with a stronger impact on the volume. Preeruptive seismicity seems to be the main triggering factor for the largest volumes, with a delay of one to several days. Rain alone does not seem to trigger especially large rockfalls. We infer that repetitive vibrations from the many seismic events, combined with the action of rain, induce crack (or slip) growth in highly fractured (or granular) materials, leading to the collapse of large volumes. Regarding their spatial distribution before an eruption, the largest rockfalls seem to migrate toward the location of magma extrusion.
Reconstruction of 4D-CT data sets acquired during free breathing for the analysis of respiratory motion

Respiratory motion is a significant source of error in radiotherapy treatment planning. 4D-CT data sets can be useful to measure the impact of organ motion caused by breathing. But modern CT scanners can only scan a limited region of the body simultaneously and patients have to be scanned in segments consisting of multiple slices. For studying free breathing motion multislice CT scans can be collected simultaneously with digital spirometry over several breathing cycles. The 4D data set is assembled by sorting the free breathing multislice CT scans according to the couch position and the tidal volume. But artifacts can occur because there are no data segments for exactly the same tidal volume and all couch positions. We present an optical flow based method for the reconstruction of 4D-CT data sets from multislice CT scans, which are collected simultaneously with digital spirometry. The optical flow between the scans is estimated by a non-linear registration method. The calculated velocity field is used to reconstruct a 4D-CT data set by interpolating data at user-defined tidal volumes. By this technique, artifacts can be reduced significantly. The reconstructed 4D-CT data sets are used for studying inner organ motion during the respiratory cycle. The procedures described were applied to reconstruct 4D-CT data sets for four tumour patients who have been scanned during free breathing. The reconstructed 4D data sets were used to quantify organ displacements and to visualize the abdominothoracic organ motion.
Mechanical Support for Postcardiotomy Cardiogenic Shock: Has Progress Been Made?

Abstract Postcardiotomy cardiogenic shock (PCCS) complicates 0.2% to 6% of cardiac operations and is a clinical entity fraught with considerable morbidity and mortality. A previous review of this topic by our group suggested that regardless of device, only 25% of patients survived to hospital discharge. In the interim, newer technologies have entered the clinical arena. Additional contributions have been made to the literature and new databases are collecting data that are likely to provide more robust guidance for the management of these very complex patients. In this review, we update the experience of mechanical support in the PCCS patient and provide a strategy to maximize survival for a patient who develops PCCS in the community cardiac surgery center.

POINTWISE: Predicting Points and Valuing Decisions in Real Time with NBA Optical Tracking Data

Basketball is a game of decisions; at any moment, a player can change the character of a possession by choosing to pass, dribble, or shoot. The current state of basketball analytics, however, provides no way to quantitatively evaluate the vast majority of decisions that players make, as most metrics are driven by events that occur at or near the end of a possession, such as points, turnovers, and assists. We propose a framework for using player-tracking data to assign a point value to each moment of a possession by computing how many points the offense is expected to score by the end of the possession, a quantity we call expected possession value (EPV). EPV allows analysts to evaluate every decision made during a basketball game – whether it is to pass, dribble, or shoot – opening the door for a multitude of new metrics and analyses of basketball that quantify value in terms of points. In this paper, we propose a modeling framework for estimating EPV, present results of EPV computations performed using playertracking data from the 2012-13 season, and provide several examples of EPV-derived metrics that answer real basketball questions.
SPARK, a confidential web-based template for self and peer assessment of student teamwork: benefits of evaluating across different subjects

Students often enjoy learning in teams and developing teamwork skills, but criticise team assessment as unfair if there is equal reward for unequal contributions. This paper describes the design, implementation and evaluation in four subjects of the Self and Peer Assessment Resource Kit (SPARK), a web-based template which aims to improve learning from team assessment tasks and make the assessment fairer for students. Students benefit because the webbased template improves confidentiality and the potential for accurate assessment of relative contributions. Academics benefit through the potential for improving student learning from teamwork tasks, and saving time by automating the process of calculating self and peer adjustments of assessment grades, especially attractive for large enrolments. Benefits accrue to the institution and wider academic community because the template suits a range of group assessment situations. Based on experiences gained over five years of developing, evaluating and implementing SPARK, this paper aims to illustrate the potential benefits of the template to potential users and more critically, to use what was learned from implementing the template across a range of subjects to alert others to key issues for evaluating and disseminating educational technology innovations.
Inhibition of preadipocyte differentiation and adipogenesis by zinc‐α2‐glycoprotein treatment in 3T3‐L1 cells

Zinc‐α2‐glycoprotein (ZAG) is associated with the loss of adipose tissue in cancer cachexia, and has recently been proposed to be a candidate factor in the regulation of bodyweight. The aim of the study was to investigate the effects of ZAG on the proliferation and differentiation of 3T3‐L1 preadipocytes.
Continuous Monitoring of High‐Rise Buildings Using Seismic InterferometryContinuous Monitoring of High‐Rise Buildings Using Seismic Interferometry

The linear seismic response of a building is commonly extracted from ambient vibration measurements. Seismic deconvolution interferometry performed on ambient vibrations can be used to estimate the dynamic characteristics of a building, such as its shear-wave velocity and its damping. The continuous nature of the ambient vibrations allows us to measure these parameters repeatedly and to observe their temporal variations. We used 2 weeks of ambient vibrations, recorded by 36 accelerometers that were installed in the Green Building at the Massachusetts Institute of Technology campus, to monitor the shear wavespeed and the apparent attenuation factor of the building. Because of the low strain of the ambient vibrations, we observed small speed changes followed by recoveries. We showed that measuring the velocity variations for the deconvolution functions, filtered around the fundamental-mode frequency, is equivalent to measuring the wandering of the fundamental frequency in the raw ambient vibration data. By comparing these results with local weather parameters, we showed that the air humidity is the dominating factor in the velocity variations of the waves in the Green Building, as well as the main force behind the wandering of the fundamental mode. The one-day periodic variations are affected by both the temperature and the humidity. The apparent attenuation, measured as the exponential decay of the fundamental-mode waveforms, is strongly biased due to the amplitude of the raw vibrations and shows a more complex behavior with respect to the weather measurements. We have also detected normal-mode nonlinear interaction for the Green Building, likely due to heterogeneity or anisotropy of its structure. We found that the temporal behavior of the frequency singlets may be used for monitoring.
Evidence That Lifelong Low Dose Rates of Ionizing Radiation Increase Lifespan in Long- and Short-Lived Dogs

After the 1956 radiation scare to stop weapons testing, studies focused on cancer induction by low-level radiation. Concern has shifted to protecting “radiation-sensitive individuals. ” Since longevity is a measure of health impact, this analysis reexamined data to compare the effect of dose rate on the lifespans of short-lived (5% and 10% mortality) dogs and on the lifespans of dogs at 50% mortality. The data came from 2 large-scale studies. One exposed 10 groups to different γ dose rates; the other exposed 8 groups to different lung burdens of plutonium. Reexamination indicated that normalized lifespans increased more for short-lived dogs than for average dogs, when radiation was moderately above background. This was apparent by interpolating between the lifespans of nonirradiated dogs and exposed dogs. The optimum lifespan increase appeared at 50 mGy/y. The threshold for harm (decreased lifespan) was 700 mGy/y for 50% mortality dogs and 1100 mGy/y for short-lived dogs. For inhaled α-emitting particulates, longevity was remarkably increased for short-lived dogs below the threshold for harm. Short-lived dogs seem more radiosensitive than average dogs and they benefit more from low radiation. If dogs model humans, this evidence would support a change to radiation protection policy. Maintaining exposures “as low as reasonably achievable” (ALARA) appears questionable.
In vitro and in vivo studies for Evaluation the Genotoxicity of Mancopper

The genotoxic effects of Mancopper, a widely used fungicide of the ethylene-bis-dithiocarbamate (EBDC) group, were studied. The cytogenetic parameters, chromosome aberrations and sister chromatid exchanges (SCEs) were the main cytogenetic assays used in this study in vitro and in vivo on Swiss albino male mice. Mice splenocytes were cultured in vitro after 24 h exposure to Mancopper (Conc. 10 -3 to 10 -7 M/ml). The percentage of cell viability was increased gradually with concentration decreasing from 10 -3 to 10 -7 . It reached 82.48% in the cultures treated with 10 -7 M Mancopper /ml medium compared to 91.5% in the non- treated cultures. The concentrations 10
Fourth sound of holographic superfluids

We compute fourth sound for superfluids dual to a charged scalar and a gauge field in an AdS4 background. For holographic superfluids with condensates that have a large scaling dimension (greater than approximately two), we find that fourth sound approaches first sound at low temperatures. For condensates that a have a small scaling dimension it exhibits non-conformal behavior at low temperatures which may be tied to the non-conformal behavior of the order parameter of the superfluid. We show that by introducing an appropriate scalar potential, conformal invariance can be enforced at low temperatures.
LazyCut: content-aware template-based video authoring

Though there are many commercial video authoring tools available today, video authoring remains as a tedious and extremely time consuming task that often requires trained professional skills. To tackle this issue, this demonstration presents a novel end-to-end system, called LazyCut, which enables fast, flexible and personalized video authoring and sharing. LazyCut provides a semi-automatic video authoring and sharing system that significantly reduces users' efforts in video editing while preserving sufficient flexibility and personalization.
Hyperarticulation aids learning of new vowels in a developmental speech acquisition model

Many studies emphasize the importance of infant-directed speech: stronger articulated, higher-quality speech helps infants to better distinguish different speech sounds. This effect has been widely investigated in terms of the infant's perceptual capabilities, but few studies examined whether infant-directed speech has an effect on articulatory learning. In earlier studies, we developed a model that learns articulatory control for a 3D vocal tract model via goal babbling. Exploration is organized in the space of outcomes. This so called goal space is generated from a set of ambient speech sounds. Similarly to how speech from the environment shapes infant's speech perception, the data from which the goal space is learned shapes the later learning process: it determines which sounds the model is able to discriminate, and thus, which sounds it can eventually learn to produce. We investigate how speech sound quality in early learning affects the model's capability to learn new vowel sounds. The model is trained either on hyperarticulated (tense) or on hypoarticulated (lax) vowels. Then we retrain the model with vowels from the other set. Results show that new vowels can be acquired although they were not included in early learning. There is, however, an effect of learning order, showing that models first trained on the stronger articulated tense vowels easier accommodate to new vowel sounds later on.
An Unstructured-Grid Based Morphodynamic Model for Sandbar Simulation in the Modaomen Estuary, China

The Modaomen Estuary is the most important passageway in discharging flood and sediment of the Pearl River Delta, which is one of the most complex estuarine systems in China. Due to the coupling effect among tidal currents, waves, and sediments, an immense sandbar area evolved in the outer subaqueous delta, impeding the flood releasing during wet season, as well as salinity intrusion during the dry season. In this work, an unstructured-grid based morphodynamic model was proposed to simulate the sandbar evolution process in the Modaomen Estuary. The proposed model was constructed by using the two-dimensional shallow water equations for tidal flow, the advection-diffusion equations for salinity and suspended sediment transport, and the non-equilibrium formulation of the Exner equation for bed evolution. To simulate the wave-induced longshore currents in the Modaomen Estuary, an adaptive time-stepping approach was proposed to couple the unstructured-grid based Simulating WAves Nearshore (SWAN) model and the shallow flow model. An integrated solver is proposed for computing flow, salinity, and sediment transport fluxes simultaneously, and then the shallow water equations and advection-diffusion equations are jointly solved by a high-resolution, unstructured-grid Godunov method. Application of the model to the Modaomen Estuary, using calibrated parameter values, gives results comparable to the measured data. The butterfly shape of the sandbar in the Modaomen Estuary is considerably well simulated by the proposed model, which matches well with the measured topography.
A Sectoral Comparison of Wage Levels and Wage Inequality in Human Services Industries

The authors explore differences among for-profit, nonprofit, and local government organizations in wage levels and inequality. Based on the intrinsic-motivation perspective and agency theory, the authors hypothesize that compared to for-profit organizations, nonprofit and local government organizations (a) are less likely to provide financial incentives, (b) pay lower or higher compensation to their employees, depending on a host of factors, and (c) have less wage inequality. The authors use wage data for five narrowly defined industries in a single state (Minnesota) where all types of organization produce the same service, employ employees with similar job titles, compete in the same labor markets, and face similar regulations. They also employ detailed data from a survey administered in two of these industries. The empirical analyses lend support for the theoretical hypotheses. However, the differences across sectors are small in magnitude.
Real Number Graph Labellings with Distance Conditions

The theory of integer $\lambda$-labellings of a graph, introduced by Griggs and Yeh [J. R. Griggs and R. K. -C. Yeh, SIAM J. Discrete Math., 5 (1992), pp. 586-595], seeks to model efficient channel assignments for a network of transmitters. To prevent interference, labels for nearby vertices must be separated by specified amounts $k_i$ depending on the distance $i$, $1\le i\le p$. Here we expand the model to allow real number labels and separations. The main finding ("D-Set Theorem") is that for any graph, possibly infinite, with maximum degree at most $\Delta$, there is a labelling of minimum span in which all of the labels have the form $\sum_{i=1}^p a_i k_i$, where the $a_i$'s are integers $\ge0$. We show that the minimum span is a continuous function of the $k_i$'s, and we conjecture that it is piecewise linear with finitely many pieces. Our stronger conjecture is that the coefficients $a_i$ can be bounded by a constant depending only on $\Delta$ and $p$. We offer results in strong support of the conjectures, and we give formulas for the minimum spans of several graphs with general conditions at distance two.
