Marginality and the Organizational Socialization of Female Managers

Although social movements and legislation have provided the impetus for women to enter the managerial ranks, relatively few females have become top-level managers. Using the sociological theory of marginality, the paper explores this phenomenon and suggests that women are still caught between emerging corporate and traditional roles. Implications of this marginal status are then examined in the context of the multistaged process of organizational socialization.
Modeling dispersive dielectric media in FDTD: a systematic approach

Two popular and distinct methods to model dispersive dielectric media in finite-difference time domain are the piecewise linear recursive convolution approach and the auxiliary differential equation approach. As they are used to model the same phenomenon and address the same equations, it is reasonable to think there is a close connection between the two. As a result of exploring this connection, we propose a new approach that can be seen as an extension of the two methods and thus, to some extent, serves to unify the two. In addition, the new approach has the advantages of being 1) more systematic-allowing the treatment of different types of dispersive dielectric media in the same manner-and 2) less ad hoc-the so-called recursive accumulators can be identified naturally and automatically.
Subgroups of SL 2 ℤ generated by elementary matrices

An elementary matrix has ones down the main diagonal and at most one element off the diagonal that differs from zero. We study the subgroups of SL 2 ℤ generated by sets of elementary matrices. Specifically, we give a stringent condition that the entries of a matrix belonging to such a group must satisfy.
Acute hyperkalemia detected by alert from implantable cardioverter-defibrillator.

Two cases of implantable cardioverter-defibrillator lead impedance changes that corresponded with changes in serum potassium are described. In the first case, an audible lead alert was triggered due to a significant change in lead impedance caused by hyperkalemia. In the second case, a patient was admitted with hyperkalemia and renal failure. Device interrogation revealed a change in lead impedance corresponding to changes in serum potassium. As devices and leads become more sophisticated, their role for monitoring parameters and triggering alerts may expand to include electrolyte and other metabolic changes. (PACE 2012; 35:e276–e279)
A Scan Statistic for Continuous Data Based on the Normal Probability Model

Temporal, spatial and space-time scan statistics are commonly used to detect and evaluate the statistical significance of temporal and/or geographical disease clusters, without any prior assumptions on the location, time period or size of those clusters. Scan statistics are mostly used for count data, such as disease incidence or mortality. Sometimes there is an interest in looking for clusters with respect to a continuous variable, such as lead levels in children or low birth weight. For such continuous data, we present a scan statistic where the likelihood is calculated using the the normal probability model. It may also be used for other distributions, while still maintaining the correct alpha level. In an application of the new method, we look for geographical clusters of low birth weight in New York City.
Multi-player soccer and wireless embedded systems

Embedded systems are increasingly becoming connected through wireless networking. These devices now form the basis of many of today's consumer products including cell phones and video game controllers. In the "Software for Embedded Systems" class in the Department of Computer Science & Engineering at the University of Washington, we used the design of a multi-player video game as motivation for the principal concepts in wireless embedded systems. Each student in the class designed an accelerometer-based game controller and then, the class as a whole, developed a multi-player video game that allowed 28 players (the number of students in the course) to play simultaneously. In this paper, we first describe the context of the course and its goals followed by the hardware/software platform we used to realize the game controller. We then detail the pedagogical approach we used to collectively design the video game (loosely based on soccer) and conclude with the lessons learned from this group design experience and how we would enhance the project and course in the future.
Inferring the specific conductivity of lake water with scaled chrysophytes

Siliceous scale-bearing chrysophytes have been used successfully in reconstructing the historical pH of lake water. In addition to pH, the distributions of many taxa of scaled chrysophytes are also significantly correlated with the concentration of dissolved salt. A model (r* of 0.87) based on scaled chrysophytes, was developed with weighted averaging regression to infer the specific conductivity of lake water. The model was applied downcore in a small soft-water lake in Connecticut whose inferred pH had remained between 6.2 and 6.5 for the past 170 yr. Despite the relatively stable pH, the inferred specific conductivity had more than tripled since the turn of the century. The rise in the salt level of the lake water correlated with known changes in the watershed, including the building of lakeside cottages and establishment of a surface silica mine.
Validation of Weapon Separation Predictions Using F/A-22 Flight Test Results *

With increased emphasis on streamlining weapon system acquisition programs, ground and flight test centers are formulating Integrated Test and Evaluation (ITE thus the F/A-22 was the logical and obvious choice for a ground-to-flight validation effort. Additionally, the F/A-22 was beginning Engineering Manufacturing and Development (EMD) flight testing at Edwards AFB. Funding to carry the simulation validation effort into the flight test arena for the F/A-22 was provided from the joint AEDC/AFFTC Modeling and Simulation Test and Evaluation Resources (MASTER) project. The MASTER effort provided the opportunity to compare ground simulations with flight test for both the AIM-9M missile and the AIM-120C missile launches from the F/A-22 as well as the fuel tank separations. Earlier papers discussed the first few tests of the AIM-9M and the AIM-120C and the lessons learned from those flights. This paper discusses the comparison of simulations with flight test for the rest of the AIM-9M, AIM-120C, and fuel tank separation flight tests to date from the F/A-22.
Robust voiced/unvoiced speech classification using a neural net

The author describes development of a voiced/unvoiced speech classifier using a multilayer perceptron. The goal is to design an accurate classifier which performs well for speech outside the training set. This includes speech with background noise present and speech collected from microphones whose frequency response varies to a small degree from that used to collect the training speech. Several combinations of voicing features are examined as inputs to the classifier. Three objective functions for classifier training are compared. Performance with and without a hidden layer is compared with that of a linear discriminant designed with Fisher's method. Over 30000 frames of hand classified speech are used for training and testing. A classifier with an error rate of less than 2% on the training data is found. >
Implicit conservative schemes for the Euler equations

A new approach to a characteristic modeling scheme is presented that does not require the governing equations to be written in characteristi c variables or the flux terms to be split into positive and negative parts. The method is based on the observation that, for certain finite volume schemes, the upwind influence can be accounted for through the conditions applied at the boundaries of individual cells instead of flux differencing. The method is developed and applied to the one-dimensional nozzle flow equations for subsonic, transonic, and supersonic flows and is then extended to two dimensions using an approximate factorization. For the problem of a shock wave reflecting from a flat plate, the present solution algorithm reduces the computational work per time step by 40% of that required by standard, central difference, implicit, calculations. I. Introduction N UMERICAL methods that attempt to model the physics of the differential equations being approximated by properly accounting for the directions in which signals are propagated can be called characteristic modeling schemes. The standard approach to characteristic modeling schemes is through the implementation of upwind schemes. (See Refs. 1-7.) To devise an upwind scheme, the primative fluxes are split into contributions whose Jacobians have eigenvalues that are either >0 or <0, respectively. At every point on the numerical mesh these fluxes are then differenced either upwind or downwind of that point.
Video Game Accessibility: A Legal Approach

Video game accessibility may not seem of significance to some, and it may sound trivial to anyone who does not play video games. This assumption is false. With the digitalization of our culture, video games are an ever increasing part of our life. They contribute to peer to peer interactions, education, music and the arts. A video game can be created by hundreds of musicians and artists, and they can have production budgets that exceed modern blockbuster films. Inaccessible video games are analogous to movie theaters without closed captioning or accessible facilities. The movement to have accessible video games is small, unorganized and misdirected. Just like the other battles to make society accessible were accomplished through legislation and law, the battle for video game accessibility must be focused toward the law and not the market.
American Burn Association practice guidelines burn shock resuscitation.

Abstract : There are insufficient data to support a treatment standard treatment at this time. Guidelines - Adults and children with burns greater than 20% TBSA should undergo formal fluid resuscitation using estimates based on body size and surface area burned. - Common formulas used to initiate of resuscitation estimate a crystalloid need for 2 to 4 ml/kg body weight/%TBSA during the first 24 hours. - Fluid resuscitation,regardless of solution type or estimated need, should be titrated to maintain a urine output of approximately 0.5 1.0 ml/ kg/hr in adults and 1.0 1.5 ml/kg/hr in children. - Maintenance fluids should be administered to children in addition to their calculated fluid requirements caused by injury. - Increased volume requirements can be anticipated in patients with full-thickness injuries, inhalation injury, and a delay in resuscitation. Options - The addition of colloid-containing fluid following burn injury, especially after the first 12 to 24 hours postburn, may decrease overall fluid requirements.
Voluntary Disclosure around Actual Share Repurchases

We examine voluntary disclosure activities around actual share repurchases. We find that managers increase the percentage and magnitude of bad news announcements during the one-month period prior to repurchasing shares. We find weaker evidence that managers increase the percentage and magnitude of good news announcements during the one-month period following their repurchases. These results are consistent with Barclay and Smith's (1988) conjecture that share repurchases, unlike dividends, provide managers with additional incentives to manipulate information flows. We show that managers alter the content of voluntary disclosures by providing downward-biased earnings forecasts before repurchases. Further empirical analyses indicate that managers' propensity to alter information flows prior to share repurchases increases with their ownership interest in the firm. Overall, our findings suggest that as managers continue to substitute repurchases for dividends, increasing amounts of corporate payouts will be subject to opportunistic disclosure strategies.
Spin-Lattice Relaxation in the Normal and Superconducting States of a High Tc Superconductor: La1.83Sr0.17CuO4

Polycrystalline samples of La1.83Sr0.17CuO4 were studied by pulsed NMR on the copper nucleus up to 70K. An extremely broad spectrum was observed. A Korringa constant of 14±± Ks and an energy gap of 2Δ/kBTc=1.3 were found. Homogeneous line narrowing was observed in the superconducting state. T2 data are presented for YBa2CuO7 as well.
Inductive Visualization: A Humanistic Alternative to GIS

Growing numbers of humanities researchers are turning to geographic information systems (GIS) to map spatial data and to visualize spatial relationships. This article explains the limitations inherent in GIS as a research methodology for humanistic scholarship, then introduces inductive visualization as a promising alternative that in several ways is more suitable to the acutely perceived but imprecise, often highly relational spatial content in the kinds of sources humanists rely on. The authors present examples of both GIS-based visualizations and inductive visualizations from their research on the geographies of the Holocaust, with a particular focus on using this method to identify and analyze spatiality in survivor testimony. The article concludes with reflections on the value of this flexible methodology for teaching students spatial thinking and encouraging them to find powerful means of visualizing the spatial meaning of primary sources in their research.
Preliminary Study of Effects of Movable Tip Strakes on Performance of Rectangular Wing

A preliminary study of the effects of mova ble tip strakes on the aerodynamic characteristics of a recta ngular wing model has been conducted in a wind tunnel. This is a new concept for controlling the flow field around wings. The additio n of sharp -edged slender -delta -shaped strake s significantly modified the wing ’s lift and drag . When deflected symmetrically , the strakes improved the lift -to -drag ratio of the baseline wing to a large exten t. The concept also seems to have potential for lateral control . There are some indications that the strakes might favorably influence the near -field rollu p of the trail ing vortices. This concept warrants additional more deta iled investigations using various flow visualization and measurement techniqu es.
Management of arrhythmias in heart failure.

The patient with congestive heart failure and ventricular arrhythmias is at high risk for sudden death. Reversible causes of arrhythmias should be sought and corrected. Antiarrhythmic drug therapy, even when directed by electrophysiologic studies, has been disappointing with adequate control being achieved in only about one third of patients, and uncertainties about the efficacy of such therapy in favorably altering long-term prognosis. The usefulness and limitations of specific antiarrhythmic drugs are reviewed. Surgical ablation or resection of arrhythmogenic foci is effective in selected patients. The AICD will become first-line therapy in patients at high risk for sudden death due to ventricular arrhythmias with antiarrhythmic drugs and other approaches being used to minimize the frequency of the arrhythmias.
Association of markers of endothelial dysregulation Ang1 and Ang2 with acute kidney injury in critically ill patients

The role of endothelial dysregulation with acute kidney injury (AKI) in critically ill patients is unclear. We retrospectively assessed the associations of AKI with biomarkers of endothelial function and inflammation among 948 subjects admitted to the intensive care unit (ICU) at Harborview Medical Center (Seattle, WA, USA). From plasma obtained within 24 h of enrollment, we measured angiopoietin (Ang)-1 and Ang-2 alongside biomarkers of inflammation, including interleukin (IL)-6, IL-17 and granulocyte colony-stimulating factor. We tested for associations between standardized concentrations of biomarkers and AKI, defined by serum creatinine, from ICU admission to up to 7 days later. All biomarkers of inflammation and endothelial dysfunction were associated with AKI. After adjustment for demographics, comorbidities, and IL-6 concentration, every standard deviation of Ang-1 concentration was associated with a 19 % lower risk of AKI (relative risk (RR) = 0.85, 95 % confidence interval (CI) 0.77–0.93, p < 0.001). Conversely, higher Ang-2 concentration was associated with higher risk of AKI (RR per standard deviation = 1.17, 95 % CI 1.13–1.22, p < 0.001). In critically ill patients, plasma concentration of the endothelial growth factors Ang-1 and Ang-2 are associated with AKI, independently of inflammation.
Tradeoffs between physical captures and PIT tag antenna array detections: A case study for the Lower Colorado River Basin population of humpback chub (Gila cypha)

Abstract A key component of many monitoring programs for special status species involves capture and handling of individuals as part of capture-recapture efforts for tracking population health and demography. Minimizing negative impacts from sampling, such as through reduced handling, aids prevention of negative impacts on species from monitoring efforts. Using simulation analyses, we found that long-term population monitoring techniques, requiring physical capture (i.e. hoop-net sampling), can be reduced and supplemented with passive detections (i.e. PIT tag antenna array detections) without negatively affecting estimates of adult humpback chub (HBC; Gila cypha ) survival ( S ) and skipped spawning probabilities (γʺ = spawner transitions to a skipped spawner, γ′ = skipped spawner remains a skipped spawner). Based on our findings of the array’s in situ detection efficiency (0.42), estimability of such demographic parameters would improve over hoop-netting alone. In addition, the array provides insight into HBC population dynamics and movement patterns outside of traditional sampling periods. However, given current timing of sampling efforts, spawner abundance estimates were negatively biased when hoop-netting was reduced, suggesting not all spawning HBC are present during the current sampling events. Despite this, our findings demonstrate that PIT tag antenna arrays, even with moderate potential detectability, may allow for reduced handling of special status species while also offering potentially more efficient monitoring strategies, especially if ideal timing of sampling can be determined.
Robust Peak-to-Average Ratio Reduction in OFDM with Adaptive Clipping Control

Despite their many advantages, orthogonal frequency division multiplexing (OFDM) systems have been limited by nonlinear devices such as power amplifiers and DACs due to OFDM's inherently high peak-to-average power ratio (PAR). This high PAR limits the use of high efficiency amplification devices. To reduce the PAR in OFDM systems, some low complexity tone reservation (TR) algorithms have been proposed. However, we find the existing low complexity TR algorithms can not achieve the minimum PAR when the clipping level is set below the initially unknown optimum value. To overcome this problem, in this paper we propose a robust PAR reduction technique by combining low complexity TR and adaptive clipping control. Simulation results demonstrate the robustness of the proposed method to severely low clipping levels.
Abstract IA16: Cancer as a disease of the symbiont/metaorganism

Commensal microorganisms colonize barrier surfaces of all multicellular organisms, including those of humans. For more than 500 million years commensal microorganisms and their hosts have coevolved and adapted to each other. As a result, the commensal microbiota affects many immune and non-immune functions of their hosts, and de facto the two together comprise one metaorganism. The commensal microbiota communicates with the host via biologically active molecules. Recently, it has been reported that microbial imbalance may play a critical role in the development of multiple diseases, such as cancer, autoimmune conditions, and increased susceptibility to infection. The commensal microbiota not only may affect the development, progression, and immune evasion of cancer but also have important effects on the response to cancer immune- and chemotherapy. Myeloid cells are a major component of the tumor microenvironment where they play a dual role inducing antitumor immune responses but mostly promoting immune evasion, tumor progression, and metastases formation. Myeloid cells respond to environmental factors including signals derived from commensal microbes that modulate their function and reactivity, thus impacting the response to cancer therapy.

Dural sinus stenting for idiopathic intracranial hypertension: factors associated with hemodynamic failure and management with extended stenting

Background Some patients undergoing dural sinus stenting for idiopathic intracranial hypertension (IIH) develop clinical and hemodynamic failure (recurrence of the pressure gradient) owing to stent-adjacent stenosis. Objective To characterize factors associated with hemodynamic failure, and to describe outcomes of patients after repeat stenting. Materials and methods We reviewed the initial and follow-up clinical, venographic, and hemodynamic data in 39 patients with IIH treated over 17 years with stenting. Thirty-two had follow-up angiographic and hemodynamic data at 1–99 months (mean 27.6, median 19.5 months). Eight patients were treated with 12 repeat stenting procedures, including extended stenting into the superior sagittal sinus (SSS). Results All patients had an initial successful hemodynamic result with the pressure gradient reduced from 10–43 to 0–7 mm Hg. 10/32 patients (31.3%), all women, developed new stenoses in the transverse sinus or posterior SSS above the stent with a recurrent pressure gradient. 7/9 patients with pure extrinsic stenosis of the transverse-sigmoid junction pre-stenting developed new stenoses and hemodynamic failure. All patients with hemodynamic failure who were restented had early and mid-term documented hemodynamic success at 1.7–50 months. They were free from papilledema at 3.8–50 months after the last restenting, and 11.5–99.5 months after initial stent placement (mean 45.3, median 38.5 months). Conclusions Pure extrinsic compression of the transverse-sigmoid junction and female gender were strongly associated with hemodynamic failure. Eight patients with hemodynamic failure who were restented had successful control of papilledema, including 4/4 who had extended stenting into the SSS.
Improvement of a Distributed Algorithm for Solving Linear Equations

This paper performs further improvement to a distributed algorithm for solving linear algebraic equations via multi-agent networks recently developed by Mou et al. , in which all agents’ states converge exponentially fast to the same solution to a group of linear equations by assuming each agent knows only part of the linear equations and its nearby neighbors’ states. We first prove that the algorithm proposed by Mou et al. with special initialization is able to achieve the solution that is closest to a given point in the Euclidean distance. Second, we eliminate the required initialization step used by Mou et al. by a modification to the update equation. Both analytical and numerical results are provided for validation.
Identifying behaviors that generate positive interactions between science museums and people on Twitter

ABSTRACTWhile most museums maintain active Twitter accounts, few use the social media platform in a productive manner. This study provides a detailed examination of how science museums use Twitter and suggests changes these museums should make to improve their current approach on this social media platform. A total of 5278 tweets from 27 science museums were analyzed to determine what type of tweet yields the greatest impact measured in retweets and favorites. Of those, 1422 tweets were selected for additional analysis. The results indicate that tweets with educational content lead to the greatest number of retweets and favorites. Suggestions for existing museums to improve their use of Twitter, especially with respect to improving marketing-related tweets, were created using the results of this study.
ATPS-02CONTINUOUS ADMINISTRATION OF THE NOVEL IRON-MIMETIC GALLIUM MALTOLATE INHIBITS GLIOMA GROWTH IN VITRO AND IN VIVO.

BACKGROUND: Limited treatment options and an aggressive nature make glioblastoma multiforme (GBM) a highly deadly cancer associated with poor prognosis and short survival. Gallium (Ga), an iron-mimetic metal, disrupts tumor iron homeostasis, thus effecting potential antineoplastic activity. Here we present compelling evidence that gallium maltolate (GaM) has a profound antitumor effect on GBM in vitro and in vivo. METHODS: The in vitro cytotoxic effects of GaM were measured by MTT assay in human U87 and D54 GBM cells, and cells isolated from normal rat brain. The in vivo antineoplastic effect of GaM was studied in a xenograft model that involved stereotactic inoculation of U87 cells into the right hemisphere of 8-week old male athymic rats. Following tumor growth confirmation on Day 8 post-inoculation by magnetic resonance imaging (MRI), rats received continuous intravenous (IV) administration of GaM (50 µM) for 10 days. Follow-up MRI occurred on Day 18 post-inoculation. RESULTS: In vitro, GaM profoundly inhibited the proliferation of both U87 and D54 GBM cell lines, but not control cells. The IC50 decreased 46% from 79.8 µM (3-day incubation) to 42.8 µM (5-day incubation) in U87 cells, and 24% from 51.4 µM (3 days) to 38.9 µM (5 days) in D54 cells. Removing GaM on days 3 and 5, and maintaining cells for another 5 days, caused a further decrease in IC50 (U87: 47.4% and 21.8%, respectively; D54: 11.8% and 10.3%, respectively). In vivo, rats receiving IV GaM tolerated the drug well, and no adverse effects were observed. Contrast-agent enhancing tumor volume on T1-weighted MRI increased in both treated (n = 8) and untreated (n = 7) animals, but significantly less so in treated rats. Mean percent increase in cerebral blood volume, determined from steady-state post-MION images, was 45% (controls) and 28% (treated rats) (p < 0.05). CONCLUSION: Gallium maltolate shows great promise for therapeutic potential in GBM.
Culturally Sensitive Care: Enlisting Community Partners to Meet Mexican American Caregiver Needs.

Background Culturally sensitive interventions are needed to assist Mexican American (MA) patients with cancer and their family members in managing their care, navigating the healthcare system, and decreasing disparities in healthcare outcomes for Hispanics with cancer. Objectives The objectives of this study were to understand the meaning of culturally sensitive care for oncology clinic healthcare providers and to assess the usefulness and feasibility of the role of a promotora de salud to meet caregiver needs. Methods This study involved focus groups of 18 diverse providers who provided data for qualitative analyses. Findings The findings (themes) defined the facilitators of and barriers to culturally sensitive care and the perceived role of a promotora de salud to support the healthcare team and improve cancer care provided by MA caregivers. In addition, promotoras de salud can help reduce health costs by decreasing patient clinic visits.
MuTrans: A multi-channel network coding approach to mobile data collection

The advantages of using of the mobile sinks (MSs) to perform data collection from Wireless Sensor Networks (WSNs) are now widely recognized. This is because the MS data collectors can service isolated systems and reduce energy expenditures by minimizing the need for multi-hop networking. However, it remains a challenging problem to support collection activities efficiently within the relevant class of predictable but uncontrollable MSs. This paper presents MuTrans, a novel multi-channel protocol that uses both clustering and network coding techniques to increase the reliability and reduce the latency of data collection in predictable and uncontrollable MS systems. A fairness data uploading scheduling to a mobile collector is presented based on assigning a method for load balancing. The implementation is described by using multiple channels for increased throughput and incorporating network coding for improved reliability. Our evaluation of data aggregation in the presence of packet errors shows that MuTrans can significantly reduce the latency for data collection, thus providing strong support for mobile data collection.
Improvement of the Cathode Electrolyte Interphase on P2-Na2/3Ni1/3Mn2/3O2 by Atomic Layer Deposition

Atomic layer deposition (ALD) is a commonly used coating technique for lithium ion battery electrodes. Recently, it has been applied to sodium ion battery anode materials. ALD is known to improve the cycling performance, Coulombic efficiency of batteries, and maintain electrode integrity. Here, the electrochemical performance of uncoated P2-Na2/3Ni1/3Mn2/3O2 electrodes is compared to that of ALD-coated Al2O3 P2-Na2/3Ni1/3Mn2/3O2 electrodes. Given that ALD coatings are in the early stage of development for NIB cathode materials, little is known about how ALD coatings, in particular aluminum oxide (Al2O3), affect the electrode–electrolyte interface. Therefore, full characterizations of its effects are presented in this work. For the first time, X-ray photoelectron spectroscopy (XPS) is used to elucidate the cathode electrolyte interphase (CEI) on ALD-coated electrodes. It contains less carbonate species and more inorganic species, which allows for fast Na kinetics, resulting in significant increase in Coulo...
A 2D heterogeneous rendezvous protocol for multi-wideband cognitive radio networks

Ideally, users in cognitive radio networks (CRNs) are capable of sensing and exploiting any potential transmission opportunities in the available spectrum band ranging from 30 KHz to 300 GHz. With the multiple-diverse-band spectrum, the network can provide more radio resources and capacity to a large number of CR users. However, the multiband scenario (e.g., TV band + 2/3G band + 4/5G band) also introduces significant challenges in channel rendezvous, a fundamental operation for users in CRNs to set up their communication link on a common channel. Existing studies on channel rendezvous suffer from unacceptable long delay and high energy consumption when applied to such scenarios. In this paper, we propose a two-dimensional heterogeneous rendezvous (2D-HR) protocol which can support multi-wideband CRNs (MWB-CRNs) with a significantly reduced rendezvous delay and energy consumption for various rendezvous scenarios, such as the pair-wise rendezvous, any-wise rendezvous, and multi-wise rendezvous. The proposed design also performs better than existing efforts even when dealing with traditional single-band rendezvous. The merits of 2D-HR are proved theoretically and validated against extensive simulations. To the best of our knowledge, this is the first work that addresses heterogeneous rendezvous in MWB-CRNs.
Diversity in LIS Education Resources

In light of events in several countries that were instigated by values that are contrary to those held by the Association for Library and Information Science Education (ALISE), the ALISE Board of Directors reaffirms its commitment to, and promotion of, diversity, equality and inclusion in the library and information science (LIS) education and professional community, and condemns racism, hate, bigotry, and violence. Diversity and inclusion are core elements of the LIS curriculum. To help LIS instructors teach and promote diversity, equality, and inclusion in their curriculum, we have compiled a list of recent works. This list is intended to serve as a living document. We encourage LIS educators, professionals, and students to use these resources in relevant learning settings to further promote these values within the communities we serve. (August 24, 2017)
Early Impact of Medicaid Expansion and Quality of Breast Cancer Care in Kentucky

Background In January 2014, Kentucky expanded Medicaid coverage to include all individuals and families with incomes up to 33% above the federal poverty line. This study evaluated the early impact of Medicaid expansion on some aspects of the quality of breast cancer care in Kentucky. Study Design The Kentucky Cancer Registry was queried for all women aged 20 to 64 years diagnosed with breast cancer between 2011 and 2016. Demographic, tumor, and treatment characteristics were assessed for each year during this interval. To evaluate the association between Medicaid expansion and these parameters, these variables, along with quality metrics deriving from said variables, were compared for the years 2011 to 2013 (pre) and the years 2014 to 2016 (post). Results Of 13,625 women with breast cancer, 11,915 (59.5%) were diagnosed and treated from 2011 to 2013, and 8,127 (40.5%) were diagnosed and treated from 2014 to 2016. After Medicaid expansion, fewer patients were uninsured (3.7% post vs 1.0% pre) and more were covered by Medicaid (15.9% post vs 10.9% pre) (p Conclusions The expansion of Kentucky Medicaid in 2014 has been associated with earlier diagnosis and somewhat improved quality of breast cancer care, despite a stable disease incidence. Additional improvements in treatment expediency will require improvements in patient outreach and healthcare infrastructure.
A closed form for the symbol of the resolvent parametrix of an elliptic operator

This exposition is addressed primarily to people who do not know much about pseudodifferential operators but have some background in quantum physics. In fact, however, every physicist is already familiar with pseudodifferential operators, if not by that name. Apart from some technical conditions (which will be ignored in this informal presentation), a pseudodifferential opcrator is what in quantum mechanics is called a function of both position and momentum. The Fourier transformation,
Effect of surface treatments on electrical properties of β-Ga2O3

The effect of various combinations of gaseous (ultraviolet/O3), liquid (HCl, buffered oxide etch, and H2O2), or plasma (CF4 and O2) treatments of the surface of β-Ga2O3 was quantified by current–voltage and capacitance–voltage measurements of rectifier structures. Plasma exposure (13.56 MHz, 24 kW/cm2) always led to significant degradation of the surface, as evidenced by large increases in rectifier reverse current and ideality factor (from 1.01 in control samples to ∼3.8 in plasma exposed samples, indicating additional defect-related carrier transport mechanisms) and lowering of the Schottky barrier height (from 1.21 eV in control samples to 0.75–0.86 eV in plasma exposed samples) and diode rectification ratio, with degraded reverse recovery characteristics. This was true of both CF4 and O2, even though it is known that fluorine incorporation in the near-surface leads to donor compensation and an increase in barrier height. Damage from the plasma exposure was not fully recovered by annealing at 500 °C. The O3 and liquid chemical cleans did lead to reduced reverse current in rectifiers, with no measurable decrease in barrier height, increase in ideality factor, or degradation of reverse recovery characteristics. Surfaces treated in this manner did not significantly change for anneals up to 500 °C; however, the Ni/Au contacts already show degradation after annealing at 350 °C.
Fecal short-chain fatty acid concentrations and dysbiosis in dogs with chronic enteropathy.

BACKGROUND Accumulating evidence shows an important relationship between the gastrointestinal (GI) microbiota and host health. Microbial metabolites are believed to play a critical role in host-microbial interactions. Short-chain fatty acids (SCFAs) are major end products of bacterial carbohydrate fermentation in the intestinal tract. Decreased concentrations of SCFAs have been observed in humans with GI disease. However, large-scale clinical data in dogs are lacking. HYPOTHESIS/OBJECTIVE To evaluate fecal concentrations of SCFAs and the fecal microbiota in healthy control (HC) dogs and dogs with chronic enteropathy (CE). ANIMALS Forty-nine privately owned HC dogs and 73 dogs with CE. METHODS Prospective cohort study. Fecal concentrations of SCFAs were measured using gas chromatography/mass spectrometry. Illumina sequencing and quantitative real-time polymerase chain reaction were utilized to evaluate the fecal microbiota. RESULTS Fecal concentrations (median [range] μmol/g of dry matter) of acetate were lower (P = .03) in dogs with CE (185.8 [20.1-1042.1]) than in HC dogs (224.0 [87.7-672.8]). Propionate were also lower (P < .001) in dogs with CE (46.4 [0.4-227.9]) than in HC dogs (105.9 [1.6-266.9]). Moreover, total SCFAs were lower (P = .005) in dogs with CE (268.1 [21.8-1378.2]) than in HC dogs (377.2 [126.6-927.0]). Dysbiosis in dogs with CE was characterized by decreased bacterial diversity and richness, distinct microbial community clustering compared with that in HC dogs, and a higher dysbiosis index. CONCLUSIONS AND CLINICAL IMPORTANCE Dogs with CE had an altered fecal SCFA concentration accompanied by significant changes of the fecal microbiota.
Glow discharge plasma deposition (GDPD) technique for the local controlled delivery of hirudin from biomaterials

Purpose. Biomaterials which release locally high concentrations of antithrombotic agents should lessen the thrombogenicity of the materials. To evaluate this approach, we prepared novel polyurethane matrices loaded with hirudin and coated them with 2-hydroxyethyl methacrylate (HEMA) by glow discharge plasma deposition (GDPD) to reduce the release rate. Methods. Polyurethane (BioSpan®) matrices containing hirudin and pore former (d-mannitol or BSA) were prepared by the solvent casting method. HEMA plasma deposition was then applied using GDPD technique to create a diffusional barrier film on the surface of the matrices. The effect of pore former and HEMA plasma coating on the release of hirudin was systematically investigated. Surface properties of matrices was also studied using Scanning Electron Microscopy (SEM) and Electron Spectroscopy for Chemical Analysis (ESCA). Results. The release of hirudin from BioSpan® matrix could be controlled by changing the weight fraction and particle size of pore former. HEMA plasma treatment of matrices produced a thin, highly cross-linked film on the surface. The initial burst and subsequent release of hirudin was significantly reduced after HEMA plasma coating, which suggested that the plasma disposition acted as a diffusional barrier and limited the release of hirudin incorporated in the polyurethane matrix. Conclusions. The plasma coating served as a diffusional barrier, and could work to control the release kinetics of hirudin by changing the various plasma coating conditions. Local delivery of hirudin using these biomaterials at the site of cardiovascular diseases can have the advantage of regional high levels of hirudin, as well as lowering systemic hirudin exposure, thereby minimizing the possibility of side effects.

Performance Prediction for CSR-Based SpMV on GPUs Using Machine Learning

Sparse matrix-vector multiplication (SpMV) is a critical operation and domains computing cost in a wide variety of real-world scientific and engineering applications. While many sparse storage formats and their computing kernels have been developed in recent years, CSR (Compressed Sparse Row) is still the most popular and widely used sparse storage format and CSR-Based SpMV usually has better performance for sparse matrices with large number of nonzero elements. This paper presents a performance prediction model built by using machine learning approach to accurately predict the execution time of GPU-accelerated SpMV using CSR kernel. The prediction accuracy of our proposed model is evaluated on a collection of fourteen sparse matrices. The results of our experiments performed on two different NVIDIA GPUs demonstrate the effectiveness of our proposed approach.
Protection from Endotoxin Shock by Selective Targeting of Proinflammatory Signaling to the Nucleus Mediated by Importin Alpha 5

Endotoxin shock is induced by LPS, one of the most potent virulence factors of the Gram-negative bacteria that cause sepsis. It remains unknown if either proinflammatory stress-responsive transcription factors (SRTFs), ferried to nucleus by importin α5, or lipid-regulating sterol regulatory element binding proteins (SREBPs), transported to the nucleus by importin β1, mediate endotoxin shock. A novel cell-penetrating peptide targeting importin α5 while sparing importin β1 protected 80% of animals from death in response to a high dose of LPS. This peptide suppresses inflammatory mediators, liver glycogen depletion, endothelial injury, neutrophil trafficking, and apoptosis caused by LPS. In d-galactosamine-pretreated mice challenged by 700-times lower dose of LPS, rapid death through massive apoptosis and hemorrhagic necrosis of the liver was also averted by the importin α5-selective peptide. Thus, using a new tool for selective suppression of nuclear transport, we demonstrate that SRTFs, rather than SREBPs, mediate endotoxin shock.
Sex, Obesity, Diabetes, and Exposure to Particulate Matter among Patients with Severe Asthma: Scientific Insights from a Comparative Analysis of Open Clinical Data Sources during a Five-day Hackathon

This special communication describes activities, products, and lessons learned from a recent hackathon that was funded by the National Center for Advancing Translational Sciences via the Biomedical Data Translator program ('Translator'). Specifically, Translator team members self-organized and worked together to conceptualize and execute, over a five-day period, a multi-institutional clinical research study that aimed to examine, using open clinical data sources, relationships between sex, obesity, diabetes, and exposure to airborne fine particulate matter among patients with severe asthma. The goal was to develop a proof of concept that this new model of collaboration and data sharing could effectively produce meaningful scientific results and generate new scientific hypotheses. Three Translator Clinical Knowledge Sources, each of which provides open access (via Application Programming Interfaces) to data derived from the electronic health record systems of major academic institutions, served as the source of study data. Jupyter Python notebooks, shared in GitHub repositories, were used to call the knowledge sources and analyze and integrate the results. The results replicated established or suspected relationships between sex, obesity, diabetes, exposure to airborne fine particulate matter, and severe asthma. In addition, the results demonstrated specific differences across the three Translator Clinical Knowledge Sources, suggesting cohort- and/or environment-specific factors related to the services themselves or the catchment area from which each service derives patient data. Collectively, this special communication demonstrates the power and utility of intense, team-oriented hackathons and offers general technical, organizational, and scientific lessons learned.
Why are humor styles associated with well-being, and does social competence matter? Examining relations to psychological and physical well-being, reappraisal, and social support

Abstract Two studies examined relations of humor styles with well-being, social support, cognitive reappraisal, and social competence. In Study 1 (N = 108), self-enhancing and affiliative humor were associated fewer health difficulties and less psychological distress, mediated by reappraisal and social support, respectively. Self-defeating humor was associated with greater distress, mediated by both reappraisal and social support. Social competence moderated the relation of aggressive humor with social support: Individuals high on both aggressive humor and communication difficulties reported the least support. Study 2 followed undergraduates (N = 193) over ten weeks. T1 results for psychological distress replicated Study 1. Social support and reappraisal mediated relations of humor styles with T1 distress, and social support indirectly mediated the relation of aggressive humor with increased T2 distress. Aggressive humor was associated with T1 health difficulties, and self-defeating humor predicted greater health difficulties over time. Reappraisal and social support indirectly mediated the relation of self-enhancing and affiliative humor with fewer T1 health difficulties, and social support indirectly mediated the relation of aggressive humor with increased health difficulties over time. Communication difficulties moderated the relation of aggressive humor with fewer T1 positive interactions and greater somatic symptoms over time. Relations largely held controlling for shared variance among humor styles.
LACC1 Required for NOD2-Induced, ER Stress-Mediated Innate Immune Outcomes in Human Macrophages and LACC1 Risk Variants Modulate These Outcomes.

Summary LACC1 genetic variants are associated with multiple immune-mediated diseases. However, laccase domain containing-1 (LACC1) functions are incompletely defined. We find that upon stimulation of the pattern-recognition receptor (PRR) NOD2, LACC1 localizes to the endoplasmic reticulum (ER) and forms a complex with ER-stress sensors. All three ER-stress branches, PERK, IRE1α, and ATF6, are required for NOD2-induced signaling, cytokines, and antimicrobial pathways in human macrophages. LACC1, and its localization to the ER, is required for these outcomes. Relative to wild-type (WT) LACC1, transfection of the common Val254 and rare Arg284 immune-mediated disease-risk LACC1 variants into HeLa cells and macrophages, as well as macrophages from LACC1 Val254 carriers, shows reduced NOD2-induced ER stress-associated outcomes; these downstream outcomes are restored by rescuing ER stress. Therefore, we identify ER stress to be essential in PRR-induced outcomes in macrophages, define a critical role for LACC1 in these ER stress-dependent events, and elucidate how LACC1 disease-risk variants mediate these outcomes.
