Shutting Down a Consortial Digital Repository Service

ABSTRACTThis column examines the lifecycle of one consortial digital repository service, the Alliance Digital Repository. Though the consortial service provided important infrastructure for members, the nature of digital repository work made it difficult to realize economies of scale. After eight years, members discontinued the shared service and replaced it with single-institution repositories that they could more readily support with the resources available to them. Based on my experiences helping members transition from shared to single-institution repositories, I offer advice for administrators planning or participating in consortial digital repository services.
70 THE EFFECT OF LEFT VENTRICULAR ASSIST DEVICE THERAPY ON MYOCARDIAL FIBROSIS AND HEMODYNAMIC FUNCTION.

Purpose Left ventricular assist device (LVAD) therapy has emerged as a viable means for bridging to transplantation in end-stage heart failure patients. There has been conflicting evidence for the effect of this therapy on myocardial interstitial fibrosis, which may play a role in LVAD-induced myocardial recovery. We seek to elucidate the relationship(s) between changes in fibrosis during LVAD support and the following factors: the type of device implanted (continuous vs pulsatile), the duration and mode of support, and the hemodynamic impact of device operation. Methods Left ventricular pressure, aortic pressure (AoP), aortic flow, and VAD flow waveforms were recorded intraoperatively at the time of LVAD implant and explant. Myocardial tissue samples were obtained from the left ventricle at time of implant and explant. Collagen-stained tissue samples (1 pre- and 1 post-VAD slide for each of three patients) were analyzed for percent fibrosis. All methods were executed as part of an IRB-approved clinical study, with appropriate informed consent of all involved patients. Results At present, three patients have undergone both LVAD implantation and explantation. Those patients receiving a continuous-flow LVAD (CF-LVAD, n = 2) demonstrated a reduction in percent fibrosis from time of LVAD implant to time of explant, whereas those receiving a pulsatile-flow LVAD (PF-LVAD, n = 1) demonstrated an increase in percent fibrosis. Furthermore, of the two continuous-flow patients, the patient with lower preimplant fibrosis demonstrated a greater reduction in percent fibrosis during the duration of support, evidenced by changes from 4.9 to 2.4% fibrosis and 9.8 to 9.0% fibrosis during LVAD support in these two patients. Hemodynamic recordings indicate a marked reduction in pulsatility of AoP with the CF-LVAD vs the PF-LVAD, which preserves physiological pulsatility. Also, following LVAD support in a CF-LVAD patient, baseline AoP was decreased from pre-VAD status. Conclusions The type of device and level of preimplant fibrosis may play a role in determining the direction and magnitude of change in myocardial fibrosis due to LVAD support. Moreover, clear differences in the hemodynamic impact of these two devices might reflect an underlying mechanism for the different changes in fibrosis seen with these two device types. In future work, more complete hemodynamic data will be used to calculate indices of function that will be correlated with histological findings in order to strengthen our understanding of the relationship between structural and functional changes brought about by LVAD support.
The Logic of Minority Rights

In this paper, we address three questions regarding minority party rights in legislatures. First, why does a majority allow for minority rights? Second, what motivates the use of the rights by legislative minorities? And third, given the majority’s self-interested motivation for the provision of minority rights, why do minority parties continue to use them? Prior research has attempted to answer these questions individually by focusing on either the role minority rights play in fulfilling legislatures’ normative system function or the isolated strategic calculations of legislative majorities and minorities. By considering actor’s strategies in isolation, these theories do not fully incorporate the interactions between majorities and minorities. Our approach unifies the multiple facets of minority rights through the use of a formal model. In our model, a majority party proposes a policy and a minority party decides to use their rights to bring the majority's proposal to the public's attention. Both parties are concerned with appeasing core supporters while simultaneously trying to improve their electoral prospects by catering to an undecided voter. Our model shows that given a level of uncertainty about the public's preferred policy, the minority will prefer to use rights to prevent the passage of extreme legislation. Additionally, the majority prefers to let the minority use its rights, which at times results in free publicity for a popular policy. Our conclusions suggest that legislative minorities can influence policy and that majorities need not be solely concerned with political insurance to provide for minority rights.

Creativity in Organizations: Importance and Approaches

Publisher Summary It is granted that creativity and innovation are critical to the growth and performance of organizations. The intuitive conception of creativity holds that it involves the production of new ideas. Creativity is not simply a matter of idea production—although this may be an important influence on creativity. Rather, creativity is defined as the production of high quality, original, and elegant solutions to problems. To capitalize on creativity and innovation organizations, one must bear in mind three key considerations. First, creativity and innovation are highly complex phenomena at any given level of analysis. Second, multiple phenomena exist at the individual, group, and organizational levels. Third, the phenomena that operate at one level are not necessarily well integrated, or consistent with, those operating at other levels. Complexity, multiple levels, and inconsistencies in effects across levels present all organizations with a challenge in their attempts to encourage creativity and innovation.
Assessment of Patient Adherence to Direct Oral Anticoagulant vs Warfarin Therapy

Context Direct oral anticoagulants (DOACs) may be as effective as, and at times safer than, warfarin. Because DOACs do not require regular serum level monitoring, patients' interaction with the health care system may be reduced. To the authors' knowledge, although studies have evaluated warfarin adherence, few studies have evaluated the real-world adherence to DOACs. Objective To evaluate whether a difference exists between medication adherence of patients taking DOACs vs patients taking warfarin. Methods The electronic medical records of the Anticoagulation Clinic database at Mayo Clinic in Scottsdale, Arizona, were reviewed. Inclusion criteria were adults taking DOACs and a matching cohort taking warfarin between January 1, 2011, and December 30, 2013. The Morisky Medication Adherence Scale-8 item, a validated medication adherence tool, was used to evaluate adherence in both cohorts, and the qualitative covariates were analyzed using ordinal logistic regression. Results Of 324 surveys that were sent, 110 patients (34.0%) responded. Most patients took DOACs for atrial fibrillation, and few took DOACs for venous thromboembolism. Overall, 60 of 66 patients (90.9%) in the DOAC group and 42 of 44 patients (95.5%) in the warfarin group reported medium or high adherence. Difference in adherence scores between the 2 groups was not statistically significant (P=.8). Conclusion Similar adherence was noted between DOACs and warfarin regardless of the frequency of serum level monitoring.
Bird Feeders as Locations for Skunk Uptake of Oral Rabies Vaccine Baits

Abstract Significantly more (54%, P=0.003) placebo baits placed under 26 bird feeders in Arizona, US were removed by striped skunks (Mephitis mephitis) than at paired, nonfeeder locations (19%). Baiting at bird feeders could supplement traditional oral rabies vaccine bait placement in urban-suburban areas while engaging the public in rabies control efforts.
Aging, Cognition, and Technology Systems

In today’s healthcare environment, patients are increasingly expected to assume more responsibility in managing their health. As technology is becoming ubiquitous in healthcare, self-management of one’s health typically requires the patient to interact with a variety of technologies. These changes in the healthcare system are coupled with a rapid aging of the US population, resulting in a greater need for technologies to assist older adults in managing their health. However, age-related declines in cognitive abilities can impact the success with which older adults are able to use healthcare technologies. To be useful to and useable by older adults, technology must be compatible with the needs, preferences, and abilities of diverse older adult populations. This chapter provides an overview of aging, cognition, and technology systems, with a focus on the implications for use of healthcare technology and the capability of technology to support cognitive aging. We also discuss factors that influence the adoption of technology among older adults and provide a case study on the interdisciplinary collaboration necessary for successful technology development.
Handling problems in input streams: a survey of beginning C++ textbooks

C++ has complex rules for handling of invalid input, e.g., whenever a program tries to read an integer but the input is not numeric. Although this is a frequent occurrence in everyday life, this case is ignored in some textbooks and given cursory or incorrect treatment in others. In this paper we survey a variety of C++ textbooks from major publishers to see how they treat invalid input. Due to the way C++ handles invalid input, this also requires a focus on end of file handling. We discuss correct and incorrect ways to handle these issues. Then we classify thirteen textbooks from major publishers according to their coverage of the topics and the examples they give.
The Intriguing Occurrence of Segmental Arterial Mediolysis: Case Report and Concise Literature Review.

BACKGROUND Segmental medial arteriolysis (SAM) is a unique arteriopathy highlighted by significant lytic changes in the medial wall of the blood vessels and can present from vague gastrointestinal discomfort to catastrophic abdominal bleeding and shock. We hereby present a concise review of this rare phenomenon with historic perspectives, epidemiology, and current concepts of etiology, pathogenesis, relevant clinical associations, treatment modalities, prognosis and future directions in SAM. CONCLUSION In addition, we present an interesting occurrence of this intriguing phenomenon in a forty-eight year old lady at our institution who presented with vague symptomatology and was an extremely challenging diagnosis. This highlights the importance of timely detection and institution of therapeutic or preventive strategies to minimize future catastrophic events.
Reshaping Aspirations: The Effects of the Great Recession on College Major Choice

College major choice is one of the most complex human capital investment problems. When a recession hits, not all majors are affected in the same way. In this project, I first examine how the labor market outcomes of individuals with different majors were affected by the Great Recession using American Community Survey (ACS). I find that Psychology, Religion and Theology, and Social Service Professions are the majors that are less adversely affected by the Great Recession. I then analyze whether and how the Great Recession affected the major choices of college students in the US by utilizing state-level variation on the severity of reces- sion and using institution level data obtained from Integrated Postsecondary Education Data System (IPEDS). Using differences in differences methodology, I find that there is substantial decrease in the degrees awarded in Education and sizable increase in the degrees awarded in Life Sciences, Psychology and Religion and Theology in the severely affected states during the post-recession period. The findings suggest that college students understand which majors are less adversely affected by the recession and substitute towards those majors.
On underresolved simulations of compressible turbulence using an entropy-bounded DG method: Solution stabilization, scheme optimization, and benchmark against a finite-volume solver

Abstract This work focuses on assessing a set of discontinuous Galerkin (DG) discretization methods for high-fidelity simulations of compressible turbulence, considering a range of conditions that include very high turbulence Mach numbers. The sensitivities of numerical results to solution-stabilization techniques, viscous/inviscid flux formulations, hp-refinement, and operating conditions are investigated. Emphasis is placed on an entropy-bounded DG (EBDG) method that can genuinely enforce physical-realizability constraints for discrete solutions. The behaviors of EBDG solutions are characterized in a set of underresolved simulation settings. It is found that for turbulence at low and moderate Mach numbers, an increase in polynomial order (p-refinement) is more effective in capturing turbulence characteristics, while for highly compressible turbulence regimes, h-refinement becomes beneficial. The EBDG method is further benchmarked against an optimized finite-volume (FV) scheme that has second-order accuracy on generic meshes while retaining fourth-order accuracy on Cartesian meshes. As a result of this fact, the benchmark study shows that on regular hexahedral meshes FV scheme is less costly than the EBDG scheme for the same accuracy, while the EBDG method becomes significantly more efficient than the FV scheme on tetrahedral and irregular meshes.
Mechanical Properties: Density and Elasticity

Should nanomaterials have properties that are any different from conventional materials? Since we have defined nanomaterials as materials where some controllable relevant dimension is of the order of 100 nm or less, there should not be a difference in properties unless the property of interest is affected by some size scale. A big part of understanding the properties of nanomaterials will therefore be developing an understanding of the length scales associated with these properties. We will approach this discussion in two parts. First, in this chapter, we will describe the simple mechanical properties of nanomaterials: the density and the linear elastic behavior. Second, in the next chapter, we will discuss the plastic behavior of nanomaterials, where the couplings of deformation mechanisms with size scale are much more complex. The objective of the current chapter is to introduce the concepts behind the coupling of the grain size and other size scales with the mechanical properties through the simple scalar property of density and through the simple linear property of elasticity.
The Immunomodulatory Capacity of an Epstein-Barr Virus Abortive Lytic Cycle: Potential Contribution to Viral Tumorigenesis.

Epstein-Barr virus (EBV) is characterized by a bipartite life cycle in which latent and lytic stages are alternated. Latency is compatible with long-lasting persistency within the infected host, while lytic expression, preferentially found in oropharyngeal epithelial tissue, is thought to favor host-to-host viral dissemination. The clinical importance of EBV relates to its association with cancer, which we think is mainly a consequence of the latency/persistency mechanisms. However, studies in murine models of tumorigenesis/lymphomagenesis indicate that the lytic cycle also contributes to cancer formation. Indeed, EBV lytic expression is often observed in established cell lines and tumor biopsies. Within the lytic cycle EBV expresses a handful of immunomodulatory (BCRF1, BARF1, BNLF2A, BGLF5 & BILF1) and anti-apoptotic (BHRF1 & BALF1) proteins. In this review, we discuss the evidence supporting an abortive lytic cycle in which these lytic genes are expressed, and how the immunomodulatory mechanisms of EBV and related herpesviruses Kaposi Sarcoma herpesvirus (KSHV) and human cytomegalovirus (HCMV) result in paracrine signals that feed tumor cells. An abortive lytic cycle would reconcile the need of lytic expression for viral tumorigenesis without relaying in a complete cycle that would induce cell lysis to release the newly formed infective viral particles.
∼14∼ – Hormones Controlling Reproduction and Molting in Invertebrates1

Publisher Summary This chapter describes hormones that are responsible for controlling reproduction and molting in invertebrates. The chapter also describes that ecdysone, the molting hormone of insects, triggers gametogenesis in certain symbiotic flagellates that inhabit the gut of the woodroach, Cryptocercus punctulatus. Normally, gametogenesis occurs in these protozoa when the host roach molts. Any procedure that interferes with molting in the roach interferes with gametogenesis in the protozoa. Since the adult insect never molts, the protozoa in adult roaches never undergo gametogenesis. It has been found in an extended series of investigations on seven species of roaches that virgin female adults produce volatile sex attractants that act via the male's antennal chemoreceptors. In addition, production of this pheromone is under the control of the corpus allatum. Allatectomy results in a failure of pheromone production that can be corrected by implantation of active glands. It appears that the active principle regulating pheromone production may be identical to that controlling egg maturation as pheromone release ceases at those stages in the reproductive cycle when the gonadotropic hormone is not produced.
Local Max-Min and Stability of Equilibria

This chapter discusses the use of the local stability of a dynamical system to classify critical points as local maxima or minima. This is exemplified using the example of a near-sighted climber on a mountain range hoping to reach the top. An ambitious but near-sighted climber on a mountain range of height h,z = h( x,y ) will move in the direction of fastest increase, Δ h . This is near-sighted in that he may head toward a local maximum or smaller peak instead of crossing a pass or saddle and climbing the highest peak in the range.
Post Processed Foundry MEMS Actuators for Large Deflection Optical Scanning

In this research effort, we developed MEMS micromirrors which are suitable for large angle deflections for optical scanning applications using the PolyMUMPs™ foundry fabrication process. This foundry process uses polysilicon and gold as the structural layers to form the bimorph beam structures which make up our actuation assembly. From both modeling and experimental testing, current micromirror designs fabricated in the PolyMUMPs™ process do not meet the deflection requirements to enable large angle scanning. As a result, we developed several post processing deposition techniques, using the PolyMUMPs™ structural layers as the baseline structure, to enable the necessary upward deflections to permit large angle scanning. In this research, we design, model, post fabricate, and test high out-of-plane MEMS actuators intended for integration with SOI micromirror arrays to enable the broadband, high fill-factor scanning applications. These arrays are designed to scan in multiple directions due to the segmented actuation design. The upward deflection is accomplished through material selection and design control (i.e., structure length, material thickness, material coefficient of thermal expansion (CTE), deposition temperature, and material layer composition) of bimorph structures. Following the post processed fabrication and sacrificial release; the initial deflection profiles are measured and compared against COMSOL™ models.
Signal Integrity Analysis on High-Density Silicon Interposer Package Technology for Next Generation Applications

New semiconductor growth engines like high-performance computing (HPC) and artificial intelligence (AI) are forcing engineers to consider new advanced packaging techniques that integrate multiple integrated circuits (ICs) in a single device. This paper investigates the SI application of a fine-line, fine-pitch, large-size silicon interposer technology for integrating a processor and high-bandwidth memory (HBM). It starts by examining the package electrical modeling methodology used in GHz I/O device modeling in a more robust and accurate way to support high-volume manufacturing and high signal quality. This is followed by frequency and time domain analysis of package models to determine the optimized design parameters to achieve good signal performance. The contribution of each package parameter to the I/O performance is investigated using S-parameter and eye diagram techniques. The S-parameter technique is used for frequency-domain analysis while eye diagrams were used for time-domain analysis. Finally, the results seen on the silicon interposer technology are compared to traditional PoP technology.
Transient Asystole after Sugammadex Administration for Immediate Reversal of Deep Blockade while on Dexmedetomidine Infusion in a Super Obese Patient

Sugammadex is increasingly used to reverse aminosteroid neuromuscular blocking agents. Dosing is calculated based on actual body weight, even for those who are obese. We report a case where a super obese patient (BMI 58.5 kg/m2) developed asystole, following coadministration with dexmedetomidine, for rapid reversal after deep blockade. Although 16mg/kg of actual body weight is recommended for prompt reversal of deep blockade, dosing adjustments may be prudent in the obese population, especially when used in conjunction with other negative chronotropic agents.

The First Station of the Long Wavelength Array

The Long Wavelength Array (LWA) will be a new multi-purpose radio telescope operating in the frequency range 10–88 MHz. Upon completion, LWA will consist of 53 phased array “stations” distributed over a region about 400 km in diameter in the state of New Mexico. Each station will consist of 256 pairs of dipole-type antennas whose signals are formed into beams, with outputs transported to a central location for high-resolution aperture synthesis imaging. The resulting image sensitivity is estimated to be a few mJy (5σ , 8 MHz, 2 polarizations, 1 hr, zenith) in 20–80 MHz; with resolution and field of view of (8′′,8◦) and (2′′,2◦) at 20 MHz and 80 MHz, respectively. All 256 dipole antennas are in place for the first station of the LWA (called LWA1), and commissioning activities are well underway. The station is located near the core of the EVLA, and is expected to be fully operational in early 2011.
Mao's Third Front: The Militarization of Cold War China

In 1964, the Chinese Communist Party (CCP) made a momentous policy decision. In response to rising tensions with the United States and Soviet Union, a top-secret massive military industrial complex in the mountains of inland China was built, which the CCP hoped to keep hidden from enemy bombers. Mao named this the Third Front. The Third Front received more government investment than any other developmental initiative of the Mao era, and yet this huge industrial war machine, which saw the mobilization of fifteen million people, was not officially acknowledged for over a decade and a half. Drawing on a rich collection of archival documents, memoirs, and oral interviews, Covell Meyskens provides the first history of the Third Front campaign. He shows how the militarization of Chinese industrialization linked millions of everyday lives to the global Cold War, merging global geopolitics with local change.
Detailed perioperative risk among patients with extreme obesity undergoing nonbariatric general surgery.

Abstract Background The obesity epidemic has spread rapidly across the United States. Although overweight and obese patients have a paradoxically lower risk for postoperative morbidity and mortality, the risks associated with extreme classes of obesity (morbid obesity, super obesity, and super-super obesity) have not been described. Methods We queried the National Surgical Quality Improvement Program database from 2012 to 2016. Of 1,815,251 surgical cases, there were 3,946 vascular cases, 237,777 emergency procedures, and 75,177 cases with missing data that were removed. The remaining 1,378,711 cases were included in this analysis. Multivariable linear and logistic regression was performed to assess the impact of body mass index on postoperative outcomes. Results Patients within the super obesity and super-super obesity groups had the highest procedure-adjusted mortality risk among all body mass index classes (odds ratio = 2.31 and 2.63, respectively). Morbid obesity and underweight groups had moderate risk (odds ratio = 1.37 and 1.88, respectively), while those in the overweight and obesity class I and II cohorts had improved or equivocal mortality risk compared to normal body mass index class patients. Risk-adjusted and unadjusted multivariable models demonstrated that extreme obesity classes (morbid obesity, super obesity, and super-super obesity) have a graduated escalation of perioperative morbidity, infectious, and critical care complications. Conclusion Further detailing extreme obesity-related risk beyond the obesity class III umbrella is necessary for accurate risk prediction, especially with the rising prevalence of elective nonbariatric surgery in this population. Preoperative risk assessment tools should consider subgroup risk adjustment to delineate true postoperative complication risk, facilitate patient education, and address modifiable risk factors before surgery.
Are Women Disadvantaged in Academic Radiology

Rationale and Objectives Women remain underrepresented in leadership positions in radiology. We sought to determine if 1) women are equitably represented in the senior author positions in radiology journals and 2) if women's contributions to the radiology literature and their individual productivity are proportional to their representation at senior academic rank. Materials and Methods The gender of 3,702 first and last authors listed for manuscripts published in nine high-impact American radiology journals was assessed between 2002-2017. For the same years, the gender composition of academic faculty and ranks based on AAMC data was queried. Statistical tests were employed to detect discrepancies and changes over time. Results First authorship by women grew from 26.9% to 37.4% and from 15.7% to 23.9% as senior author between 2002-2017 (P Conclusions Although women have proportionally increased their contribution to the radiology literature over the years, commensurate increased representation of women in senior authorship and faculty positions was not observed. Despite increased involvement of women in research over time, they remain disproportionately at junior faculty positions.

Single magnetic domain Terfenol-D microstructures with passivating oxide layer

Abstract Studies on giant magnetostrictive intermetallic compound Tb0.3Dy0.7 Fe1.92 (Terfenol-D) thin films are gaining increasing attention due to the interest in small scale magnetic structures. In this work, polycrystalline Terfenol-D thin films (60 nm) are produced using a Direct Current (DC) magnetron sputtering process and a hybrid thermal annealing approach, i.e. substrate heating and post-annealing. The crystallized Terfenol-D films are micropatterned (3 μm and 20 μm diameters) using a photolithographic method followed by Argon etching. The continuous and micropatterned thin films are characterized with XRD, SQUID and MOKE magnetometers showing properties similar to bulk polycrystalline Terfenol-D. Additional studies are conducted using X-ray absorption spectroscopy and the X-ray magnetic circular dichroism to investigate oxidation. Results show that while the top surface of these Terfenol-D structures are capped with Ta thin films, the side walls of the structures are exposed to ambient atmosphere raising the concern of oxidation issues. This work shows that a passivating oxide layer forms on the side walls of these small-scale Terfenol-D disks which is attributed to both the Ta capping layer as well as residual stresses preventing continued stress corrosion cracking caused by the oxidation process.
Ga-68 DOTATATE PET/CT demonstrating uptake in vertebral hemangioma mimicking osseous metastasis from pancreatic neuroendocrine tumor.

2027 Introduction: Ga-68-DOTATATE PET/CT is considered a standard part of staging well-differentiated neuroendocrine tumor of the pancreas, recently replacing In-111 pentetreotide SPECT/CT in this role. Uptake is not entirely specific, with various unrelated and benign entities occasionally demonstrating uptake and confounding diagnosis. A small number of reports indicate that vertebral hemangiomas can demonstrate uptake and may mimic osteolytic metastasis, altering both stage and management of disease. Methods/Results: We present a case of a 58 year old female with an arterially enhancing mass in the pancreatic head on contrast enhanced CT and subsequently diagnosed with neuroendocrine tumor of pancreas by EUS-guided FNA. Staging Ga-68-DOTATATE PET/CT demonstrated significant uptake in the pancreatic head mass (SUV max of 16.5) and mild uptake in a T8 vertebral lucent lesion (SUV max of 2.2), the latter reported as possible metastasis on the basis of abnormal uptake and lytic appearance on the nondiagnostic CT images. Contrast enhanced MRI of the spine reported high T2 and low T1 signal and enhancement in the T8 lesion, suspicious for metastasis, although an atypical hemangioma can have the same appearance. CT of the spine demonstrated a definitive appearance of hemangioma for the T8 lesion on axial CT with a “polka-dotted” appearance, though with a somewhat atypical thin sclerotic rim and absence of a well-defined “corduroy sign” on sagittal CT. Nonetheless, because of the CT appearance, a hemangioma was felt very likely to be the etiology. Definitive therapy with Whipple procedure was undertaken. On follow up about 2.5 years later, the patient was asymptomatic, chromogranin A was within normal range, and there was no evidence of disease per reports from outside imaging. Conclusions: The reader should be aware that lucent/lytic bone lesions with Ga-68-DOTATATE uptake on low-resolution CT performed with PET imaging may represent a vertebral hemangioma as opposed to metastasis, as this can impact staging and management. This has been described sporadically in the European literature. There has not been a case of In-111 pentetreotide uptake in vertebral hemangioma, perhaps due to limitations of spatial resolution of SPECT imaging or to a different uptake mechanism in hemangiomas compared to Ga-68-DOTATATE.
The Effect of Affordable Care Act Medicaid Expansions on Household Composition

Prior research has shown improvements in low-income individuals' financial well-being as a consequence of the Affordable Care Act's Medicaid expansion. Given the connection between financial well-being and housing, we investigate the extent to which the provision of Medicaid to previously ineligible, low-income childless adults affects their household composition. Using a staggered adoption difference-in-differences design on an urban sample of individuals with less than a high school degree, we find that 26 to 39 year olds experience a significant 4.2% decline in the number of individuals living in the household, which is due to living with fewer extended family members. At the same time, 26 to 39 year olds experience a relatively smaller decline in the number of rooms (1.8%), leading to a 3.1% reduction in the level of household crowding, as measured by persons per bedroom. These reductions in household crowding are strongest for Hispanic individuals and those living in areas with above-median housing costs. In comparison, there are no significant impacts on household composition for 40 to 64 year olds as a consequence of the policy.

Oxidative Phosphorylation: Chemiosmotic Coupling Hypothesis

Failure to identify chemical intermediates was aggravating but not decisive. Absence of proof is not proof of absence, and in 1960 Lehninger reassured his colleagues that “it has not seemed necessary to postulate mechanisms other than those involving the classical common intermediate to explain available data.”1 Despite that counsel, Peter Mitchell (Fig. 17.1) the next year proffered his own tally of current shortcomings and invoked a radically different mechanism.2
Gatekeeper Liability: A Response to the Financial Crisis

The first financial crisis, triggered by the burst of the U.S. housing bubble, has many causes. One such cause is the failure of gatekeepers, i.e. accounting firms and rating agencies. Consequently lawmakers on both sides of the Atlantic tightened the regulatory regimes for accountants and rating agencies, following the same path they had walked earlier, in response to financial scandals such as the one involving Enron and Worldcom. However, the liability rules for these institutions remained untouched once again so that accountants and rating agencies continue to work under skewed liability regimes. Incentives to err on the side of customers remain strong and unbalanced by adequate liability towards third parties. This article explores legislative strategies for a more symmetrical liability regime. In doing so, it takes a critical view of the recent EU Regulation No. 462/2013.
A New Rotation-Invariant Approach for Texture Analysis

Image processing and pattern recognition are one of the most important area of research in computer science. Recently, several studies have been made and efficient approaches have been proposed to provide efficient solutions to many real and industrial problems. Texture analysis is a fundamental field of image processing because all surfaces of objects are textured in nature. Thus, we proposed a new texture analysis method. In this paper, we proposed a novel texture analysis approach based on a recent feature extraction method called neighbor based binary pattern (NBP). The NBP method extract the local micro texture and is robust against rotation, which is a key problem in image processing. The proposed system extract two-reference NBP histograms from the texture in order to calculate a model of the texture. Finally, several models have been constructed to be able to recognize textures even after rotation. Textured images from Brodatz album database were used in the evaluation. Experimental studies have illustrated that the proposed system obtain very encouraging results robust to rotation compared to classical method.
Some Aspects of Urban Planning

Simultaneous recovery of a source term and an isotropic initial condition for radiative transport

In this paper, we investigate the simultaneous recovery of a source of the form $\sigma(t,x,\theta) f(x)$ (with $\sigma$? known) and an isotropic initial condition $u_{0}(x)$, using the single measurement induced by these data. This result is part of an effort to reconstruct optical properties using unknown illumination embedded in the unknown medium. More precisely, based on exact boundary controllability, we derive a system of equations for the unknown terms $f$ and $u_{0}$. The system is shown to be of Fredholm type if $\sigma$ satisfies certain positivity condition. This condition is physically meaningful when $\sigma$ is interpreted as an illumination field, and it simply requires that the incident particles visit the region over which $f$ is to be recovered. We show that for generic term $\sigma$ and weakly absorbing media, the inverse problem is uniquely solvable with a stability estimate.
Avoiding stratification in association studies

In the study of complex disease, separating causal from confounded factors is a challenge for genetic epidemiologists. Population structure can be an important source of confounding. In the context of population samples, the tools useful for overcoming the effects of population structure are described in terms of experimental design and statistical analysis. Keywords: genomic control; structured association; population substructure; confounding
The multicore programming challenge

Dual-core machines are now actively marketed for desktop and home computing. Systems with a larger number of cores exist, and more are planned. Some cores are capable of executing multiple threads. At the very high end, programmers need to design codes for execution by thousands of processes or threads and have begun to consider how to write programs that can scale to hundreds of thousands of threads. Clearly, the future is multi- and many-core, as well as many-threaded. In the past, most application developers could rely on Moore's Law to provide them with steady performance improvements. But we have entered an era in which they may have to expend considerable effort if their codes are to exploit the processing power offered by next-generation platforms. At least in the medium term, a broad variety of parallel applications will need to be developed. Existing shared memory parallel programming APIs were not necessarily designed for general-purpose computing or with many threads in mind. Distributed memory paradigms do not necessarily allow the expression of fine-grained parallelism or provide full exploitation of architectural features. The fact that threads share some resources in multicore systems makes it hard to reason about the impact of program modifications on performance and results may be surprising. Will programmers be able to use multicore platforms effectively? In this presentation, we discuss the challenges posed by multicore technology, review recent work on programming languages that is potentially interesting for multicore platforms, and discuss on-going activities to extend compiler technology in ways that may help the multicore programmer.
Effect of age, body mass index, and parity on Pelvic Organ Prolapse Quantification system measurements in women with symptomatic pelvic organ prolapse.

Aim: To evaluate the effect of age, body mass index (BMI), and parity on Pelvic Organ Prolapse Quantification (POP-Q) system measurements in women with symptomatic prolapse. Material and Methods: The charts of 603 women with symptomatic prolapse were reviewed. Patients with prior prolapse surgery or hysterectomy were excluded. POP-Q measurements were recorded by a single examiner. Data were analyzed using descriptive statistics, the Pearson's product-moment correlation, and Wilcoxon signed rank test. Results: Three hundred and eleven patients met inclusion criteria. Mean age was 63.4 years, mean parity was 2.6, and mean body mass index (BMI) was 26.6 kg/m2. Increasing age was correlated with worsening scores on Ba (r = 0.33, P < 0.0001), C (r = 0.14, P < 0.02), D (r = 0.14, P = 0.02) and Bp (r = 0.13, P = 0.02), while parity was only correlated with worsening scores on Aa (r = 0.12, P = 0.04). There was no correlation between BMI and any POP-Q data point. Conclusion: The effect of increasing parity was seen solely on point Aa in women with symptomatic prolapse. Age affected all vaginal compartments, while BMI had no impact on POP-Q data points.
The Genetics of Division of Labour in Honey Bee Colonies

Publisher Summary This chapter describes genetic characteristics that are unique to the hymenoptera, including honeybees, and presents how these characteristics, when combined with the mating behavior of queens, affect the genetic “structure” and populations of honeybee colonies. The chapter presents results that demonstrate the fundamental elements of division of labor among workers and suggests how colony-level natural selection adapts populations of colonies to their environment via changes in the behavior of individual, effectively sterile workers. It also presents theoretical models that suggest that some properties of division of labor, such as the occurrence of labor specialists and the ability to reallocate labor in the face of a changing environment, are a consequence of self-organization that may be intrinsic to many types of complex systems, including insect colonies.
Perforation of the right ventricle by pacing catheter electrode. Two cases of asymptomatic perforation with survival.

Abstract Two cases are reported of uneventful perforation of the free right ventricular wall following insertion of a pacing catheter electrode into the right ventricle. In view of the possibly lethal consequences of this complication, it is suggested that the supplest and softest available catheter be used, that the pacing electrode catheter be placed only in the right ventricular outflow tract, that its position be checked frequently roentgenographically and that it be replaced within as short time as possible by surgical implantation of an epicardial pacemaker.
Provider and pharmacist responses to warfarin drug-drug interaction alerts: a study of healthcare downstream of CPOE alerts.

Objective To categorize the appropriateness of provider and pharmacist responses to warfarin critical drug–drug interaction (cDDI) alerts, assess responses and actions to the cDDI, and determine the occurrence of warfarin adverse drug events (ADE) after alerts. Design An 18-month, retrospective study of acute care admissions at a single Veterans Affairs medical center using computerized provider order entry (CPOE). Measurements Patients included had at least one warfarin cDDI alert. Chart reviews included baseline laboratory values and demographics, provider actions, patient outcomes, and associated factors, including other interacting medications and number of simultaneously processed alerts. Results 137 admissions were included (133 unique patients). Amiodarone, vitamin E in a multivitamin, sulfamethoxazole, and levothyroxine accounted for 75% of warfarin cDDI. Provider responses were clinically appropriate in 19.7% of admissions and pharmacist responses were appropriate in 9.5% of admissions. There were 50 ADE (36.6% of admissions) with warfarin; 80% were rated as having no or mild clinical effect. An increased number of non-critical alerts at the time of the reference cDDI alert was the only variable associated with an inappropriate provider response (p=0.01). Limitations This study was limited by being a retrospective review and the possibility of confounding variables, such as other interacting medications. Conclusion The large number of CPOE alerts may lead to inappropriate responses by providers and pharmacists. The high rate of ADE suggests a need for improved medication management systems for patients on warfarin. This study highlights the possibility of alert fatigue contributing to the high prevalence of inappropriate alert over-ride text responses.
Quality of Cary-Blair Transport Medium After Aging Nineteen Months

Cary-Blair medium retains its ability to serve as a transport medium after 19 months of aging at room temperature. This eliminates the necessity for the frequent replacement of the stored supplies of this medium.
Politics and young adults: the effects of Facebook on candidate evaluation

An increasing number of people are turning to social media to find political information and discuss politics, including the technologically savvy Millennial generation. Our study looks at how young voters use social media to evaluate political candidates. Subjects were shown the Facebook walls of two U.S. politicians running for the seat of governor in the 2011 Mississippi election. Exposure was followed by semi-structured interviews to discover what knowledge they found salient. Content analysis found evidence that the knowledge they gained from Facebook influenced their evaluation of the candidates. Further, we contrast this to a control group that was exposed to related news articles without a social media component. We found that social media produced the additional voting criterion of community, which extends beyond the traditional criteria in political science literature of issues and character. Community interaction influences the vote decision.
Monopsony as a metaphor for the emerging post-union labour market

: How can employers worldwide be experiencing increasingly severe labour shortages in the face of globalization? Why don't wages rise in expanding economies? This article argues that declining union power has allowed employers to take the upper hand, setting pay and other conditions of employment as they would in a monopsonistic labour market. Rejecting the perfect competition model matching supply to demand, the authors argue that, far from being a pedagogical curiosity, monopsony's imbalance in bargaining power is widespread. Employee voice needs to be restored to counter the undesirable consequences of strong macroeconomic performance, such as wage inequality and reduced worker rights.
Can schizophrenia begin after age 44

Abstract Thirty-five patients who developed a delusional disorder after age 44 were studied to determine whether they had symptom profiles different from age-matched affectively ill patients and whether they were similar to patients described in the European literature as suffering late onset schizophrenia. Patients were predominantly women and most had auditory hallucinations. Two-thirds and first-rank symptoms of Schneider. DSM-III critera were retrospectively applied: 21 patients met all DSM-III criteria for schizophrenia except for the criterion requiring onset before age 45. Eleven of the patients met criteria for schizophreniform illness and three met criteria for paranoia. We suggest that a schizophrenia-like illness can begin after age 44 and that future versions of the Diagnostic and Statistical Manual contain a category for such patients.
