Tooling the aggregator's workbench: Metadata visualization through statistical text analysis

Digital library interoperability efforts have succeeded in making large-scale aggregation of digital collections technically feasible, to the extent that aggregations have become critical organizational tools in the data universe. As diverse digital collections are increasingly unified into aggregations data heterogeneity presents burgeoning challenges to aggregators. Comprehension of massive aggregates and efficient metadata quality analysis are aggregator imperatives that rely on scalable evaluation techniques. This paper describes novel applications of visualization techniques, based on statistical text analysis, to the evaluation and maintenance of a large-scale aggregation of descriptive, cultural heritage metadata. These techniques, and their implementation as part of an aggregator's workbench, provide new, administrator-oriented perspectives on metadata aggregations, in order to improve aggregators' capacity to evaluate metadata quality and topical coverage in a scalable way.
Role of cytoplasmic dynein in the axonal transport of microtubules and neurofilaments

Recent studies have shown that the transport of microtubules (MTs) and neurofilaments (NFs) within the axon is rapid, infrequent, asynchronous, and bidirectional. Here, we used RNA interference to investigate the role of cytoplasmic dynein in powering these transport events. To reveal transport of MTs and NFs, we expressed EGFP-tagged tubulin or NF proteins in cultured rat sympathetic neurons and performed live-cell imaging of the fluorescent cytoskeletal elements in photobleached regions of the axon. The occurrence of anterograde MT and retrograde NF movements was significantly diminished in neurons that had been depleted of dynein heavy chain, whereas the occurrence of retrograde MT and anterograde NF movements was unaffected. These results support a cargo model for NF transport and a sliding filament model for MT transport.
Background, Personal, and Environmental Influences on the Career Planning of Adolescent Girls.

This study investigated the influence of background variables (age, race/ethnicity, mother’s work status outside of the home, and socioeconomic status), personal variables (anticipatory role conflict and academic self-efficacy), and environmental variables (parental attachment and parental support) on aspects of adolescent girls’ career planning. Four hierarchical regression analyses were performed with a sample of 217 adolescent females in an urban high school. The dependent variables representing aspects of future career planning were (a) plans for the integration of work and family; (b) gender-traditionality of career choice; (c) career commitment; and (d) aspired education level. Personal variables made the greatest contribution to adolescent girls’ plans for the integration of work and family and career commitment. Background variables contributed most to gender-traditionality of career choice and aspired education level. Environmental variables did not make significant contributions to any of the de...
Dual-track pathway of bladder carcinogenesis: practical implications.

Abstract Context.—The concept of a dual-track pathway in bladder carcinogenesis postulates that bladder cancer develops via 2 distinct but somewhat overlapping pathways, termed the papillary and nonpapillary. Approximately 80% of bladder carcinomas consist of superficial exophytic papillary lesions that originate from urothelial hyperplasia. These typically low-grade papillary tumors may recur, but they rarely invade the bladder wall or metastasize. The remaining 15% to 20% of tumors represent high-grade solid nonpapillary bladder carcinoma, which arise from high-grade intraurothelial neoplasia. These tumors aggressively invade the bladder wall and have a high propensity for distant metastasis. Objective.—To summarize the scientific literature and provide a clinicopathologic review of the dual-track concept of bladder carcinogenesis with its important implications. Data Sources.—Relevant articles indexed in PubMed (National Library of Medicine) between 1974 and 2005. Conclusions.—Although the characterist...
Moral Value Structure of Laborers and Penitentiary Inmates: A Research Note

A questionnaire containing 50 moral values items was administered to white marginally middle-class laborers, white penitentiary inmates, and Negro penitentiary inmates. A comparison of the responses of the white laborers and the white penitentiary inmates revealed significant differences on 26 of 50 items, with the laborers presenting a more condemning or more "conservative" judgment on nearly all moral values items. A comparison of the white and Negro convicts revealed significant differences on eight of 50 items. On moral values or ethical judgments about behavior, it appears that differing social class subcultures and/or criminal-noncriminal subcultures produce greater divergence than do differing racial groups. T his paper reports the findings of a study which sampled the moral value structure of noncriminal labor union members and white and Negro penitentiary inmates. This project follows earlier research in moral value structure conducted by Crissman, and by Rettig and Pasamanick. Crissman sampled college students, using a 50-item questionnaire, and noted changes in moral values over a 20year period.1 The unscaled items in Crissman's * The total project of which this paper is a part was supported by the Ohio State University Delinquency Research Project directed by Walter C.

A Chemical Ionization Mass Spectrometer for ambient measurements of Ammonia

Abstract. This study presents a chemical ionization mass spectrometer (CIMS) for fast response, in-situ measurements of gas phase ammonia (NH3). The NH3 background level detected with the CIMS ranged between 0.3–1 ppbv, with an uncertainty of 30 pptv under optimized conditions. The instrument sensitivity varied from 4–25 Hz/pptv for >1 MHz of reagent ion signals (protonated ethanol ions), with a 30% uncertainty estimated based on variability in calibration signals. The CIMS detection limit for NH3 was ~60 pptv at a 1 min integration time (3 sigma). The CIMS time response was
The effect of mild-to-moderate hearing loss on auditory and emotion processing networks

We investigated the impact of hearing loss on emotional processing using task- and rest-based functional magnetic resonance imaging. Two age-matched groups of middle-aged participants were recruited: one with bilateral high-frequency hearing loss (HL) and a control group with normal hearing (NH). During the task-based portion of the experiment, participants were instructed to rate affective stimuli from the International Affective Digital Sounds database as pleasant, unpleasant, or neutral. In the resting state experiment, participants were told to fixate on a '+' sign on a screen for five minutes. The results of both the task-based and resting state studies suggest that NH and HL patients differ in their emotional response. Specifically, in the task-based study, we found slower response to affective but not neutral sounds by the HL group compared to the NH group. This was reflected in the brain activation patterns, with the NH group employing the expected limbic and auditory regions including the left amygdala, left parahippocampus, right middle temporal gyrus and left superior temporal gyrus to a greater extent in processing affective stimuli when compared to the HL group. In the resting state study, we observed no significant differences in connectivity of the auditory network between the groups. In the dorsal attention network, HL patients exhibited decreased connectivity between seed regions and left insula and left postcentral gyrus compared to controls. The default mode network was also altered, showing increased connectivity between seeds and left middle frontal gyrus in the HL group. Further targeted analysis revealed increased intrinsic connectivity between the right middle temporal gyrus and the right precentral gyrus. The results from both studies suggest neuronal reorganization as a consequence of hearing loss, most notably in networks responding to emotional sounds.
New Deal Liberalism and Racial Liberalism in the Mass Public, 1937-1952

Few transformations have been as important in American political history as the incorporation of African Americans into the Democratic Party coalition over the course of the 1930s-60s and the embrace of racial conservatism on the part of many Republicans. This paper, which is part of a broader book project, focuses on changes in mass opinion among Democratic and Republican partisans from the late 1930s through the 1960s. It traces, over time, the relationship between New Deal economic liberalism and racial liberalism, and between economic policy conservatism and racial conservatism. A key initial finding is that by the late 1930s, economically-liberal northern white Democratic voters were especially pro-civil rights, while economically-conservative northern Republican voters were particularly hostile. This suggests that there was a connection between attitudes towards the economic programs of the New Deal and racial liberalism early on. One of the goals of the book will be to understand where that connection came from, along with its implications for subsequent developments.
When the Saints went marching in: social identity in the world champion New Orleans Saints Football Team and its impact on their host city.

Social identity theory is used to explain behaviors, thoughts, and feelings associated with group membership. This study focuses on the New Orleans Saints National Football League (NFL) team and its effect on citizens of its host city as well as fans from the surrounding region. While a large body of research shows little evidence that new stadiums and professional sports teams make a significant economic impact on the region, some findings have shown that sports teams can provide intangible benefits. These intangible benefits are often related to the positive associations fans of the team have by considering themselves a part of that particular in-group. This study applies social identity theory to the New Orleans Saints’ fan base and discusses the reactions of the team’s fans during the 2009 Super Bowl–winning season as reported in national, regional, and local publications.
Rethinking the role of interpersonal influence processes in alcohol intervention situations

Abstract In a review of the literature on personal intervention practices in adult alcoholism contexts (termed the home treatment method), Thomas and Seibold (1993) identified several points of overlap between this research and traditional interpersonal influence studies. Our aim in this paper is to extend that analysis to studying alcohol intervention processes in the college environment from an interpersonal influence perspective. We attempt this, first, by reviewing literature on the extent of the alcohol use/abuse problem in the college environment. Second, we demonstrate the importance of interpersonal influence processes to the alcohol intervention context and critically review the current state of research dealing with intervention strategies used in the college environment. Finally, following discussion of the conceptual and methodological concerns associated with research in the alcohol intervention area, we offer a reconceptualization of interpersonal influence processes in college students’ alc...
Cohabiting family members share microbiota with one another and with their dogs

The human body is home to many different microorganisms, with a range of bacteria, fungi and archaea living on the skin, in the intestine and at various other sites in the body. While many of these microorganisms are beneficial to their human hosts, we know very little about most of them. Early research focused primarily on comparing the microorganisms found in healthy individuals with those found in individuals suffering from a particular illness. More recently researchers have become interested in more general issues, such as understanding how these collections of microorganisms, which are also known as the human microbiota or the human microbiome, become established, and exploring the causes of similarities and differences between the microbiota of individuals. We now know that the communities of microorganisms found in the intestines of genetically related people tend to be more similar than those of people who are not related. Moreover, the communities of microorganisms found in the intestines of non-related adults living in the same household are more similar than those of unrelated adults living in different households. We also know that the range of microorganisms found in the intestine changes dramatically between birth and the age of 3 years. However, these studies have focused on the intestine, and little is known about the effect of relatedness, cohabitation and age on the microbiota at other body sites. Song et al. compared the microorganisms found on the skin, on the tongue and in the intestines of 159 people—and 36 dogs—in 60 families. They found that co-habitation resulted in the communities of microorganisms being more similar to each other, with those on the skin being the most similar. This was true for all comparisons, including human pairs, dog pairs and human–dog pairs. This suggests that humans probably acquire many of the microorganisms on their skin through direct contact with their surroundings, and that humans tend to share more microbes with individuals, including their pets, with which they are in frequent contact. Song et al. also discovered that, unlike what happens in the intestine, the microbial communities on the skin and tongue of infants and children were relatively similar to those of adults. Overall, these findings suggest that the communities of microorganisms found in the intestine changes with age in a way that differs significantly from those found on the skin and tongue.
The Impact of Search Algorithms in Automated Program Repair

Abstract Automated program repair (APR) techniques locate and fix faults automatically. In order to fix faults, APR applies a set of program modification operators (PMOs) to modify faulty programs. A potential repair is found when APR applies a PMO that fixes a fault. A brute-force search algorithm applies all PMOs in a predefined order until a potential repair is found. Brute-force can guarantee a fix but lowers APR performance, especially when it uses many PMOs. Stochastic search algorithms, such as a genetic algorithm, efficiently search the modifications space for a PMO that fixes a fault. In this paper, we conduct a comprehensive evaluation of the impact on APR effectiveness, APR performance, and the quality of potential repairs of three stochastic search algorithms:(1) a genetic algorithm (GA), (2) a genetic algorithm without a crossover operator (GAWoCross), and (3) a random search (RS). Our evaluation using 41 faulty versions of six different C programs shows that RS improves APR effectiveness and performance, but GA and GAWoCross improve the quality of potential repairs by generating more validated repairs, and potential repairs that failed fewer regression tests compared to RS.
Beyond Patient Classification: Using Individual Patient Characteristics in Appointment Scheduling

Scheduling patients involves a trade-off between the productivity of the service provider and customer service. This study considers how outpatient medical facilities can improve their appointment scheduling by incorporating individual patient information in the scheduling process. Specifically, we obtain data on patient characteristics and examination durations from a health clinic, describe how that data can be used to predict patient examination durations in the clinic's appointment scheduling system, and evaluate the benefit of using individual patient characteristics over a conventional classification method. Computational results illustrate this method of patient scheduling reduces an overall cost function comprised of patient wait time, physician idle time, and over time by up to 24.2%, particularly when patients are sequenced with short duration patients being scheduled first. Several environmental characteristics are found to play critical roles in determining the magnitude of the benefit, including patient punctuality, no-show probability, the clinic duration, the appointment rule used for scheduling, and the ratio of the physician's idle time cost to the patient wait cost. We also detail and evaluate a practical procedure for using heterogeneous scheduling under a fixed schedule.
A comparison of reconstruction methods for undersampled atomic force microscopy images

Non-raster scanning and undersampling of atomic force microscopy (AFM) images is a technique for improving imaging rate and reducing the amount of tip-sample interaction needed to produce an image. Generation of the final image can be done using a variety of image processing techniques based on interpolation or optimization. The choice of reconstruction method has a large impact on the quality of the recovered image and the proper choice depends on the sample under study. In this work we compare interpolation through the use of inpainting algorithms with reconstruction based on optimization through the use of the basis pursuit algorithm commonly used for signal recovery in compressive sensing. Using four different sampling patterns found in non-raster AFM, namely row subsampling, spiral scanning, Lissajous scanning, and random scanning, we subsample data from existing images and compare reconstruction performance against the original image. The results illustrate that inpainting generally produces superior results when the image contains primarily low frequency content while basis pursuit is better when the images have mixed, but sparse, frequency content. Using support vector machines, we then classify images based on their frequency content and sparsity and, from this classification, develop a fast decision strategy to select a reconstruction algorithm to be used on subsampled data. The performance of the classification and decision test are demonstrated on test AFM images.
Dexter: Plugging-n-Playing with Data Sources in Your Browser

We present Dexter , a browser-based, general purpose data exploration system for end-users. Dexter enables end-users to easily query across multiple Web-accessible heterogeneous (semi-) structured data sources with higher expressivity than that is usually directly supported by the sources. A novelty of our approach lies in the client-sided evaluation of end-user queries. Our query evaluation technique exploits the querying capabilities of the sources and communicates directly with the sources whenever possible. Dexter-Server, the server-sided component of Dexter, merely acts as a proxy for accessing sources that are not directly accessible from a Dexter-Client. Dexter also supports organizational internal and personal data sources while respecting end-users' security and privacy. We present the results of our evaluation of Dexter or scenarios that involve querying across data about the U.S. Congerss, the U.S. Code, and feeds from popular social networks. We discuss the applicability of Dexter for data about cities.
Determining energy and climate market policy using multiobjective programs with equilibrium constraints

Energy and climate market policy is inherently multiobjective and multilevel, in that desired choices often conflict and are made at a higher level than influenced actors. Analyzing tradeoff between reducing emissions and keeping fuel prices low, while seeking compromise among producers, traders, and consumers is the crux of the policy problem. This paper aims to address this issue by combining multiobjective optimization problems, which allow the study of tradeoff between choices, with equilibrium problems that model the networks and players over which these policies are chosen, to produce a formulation called a Multiobjective Program with Equilibrium Constraints. We apply this formulation to the United States renewable fuel market to help understand why it has been so difficult in releasing the 2014 mandate for the RFS (Renewable Fuel Standard). The RFS ensures that a minimum volume of renewable fuel is included in transportation fuel sold in the United States. Determining the RFS volume requirements involves anticipating market reaction as well as balancing policy objectives. We provide policy alternatives to aid in setting these volume obligations that are applicable to a wide variety of climate and energy market settings and explain why the RFS is not an optimal policy for reducing emissions.
Sustained increase in 1,2-diacylglycerol precedes DNA synthesis in epidermal-growth-factor-stimulated fibroblasts. Evidence for stimulated phosphatidylcholine hydrolysis

A property common to many growth factors is that they must be present for several hours before the commitment to DNA synthesis and cell division occurs. The intracellular signals that are relevant during this period are poorly defined. We examined the formation of 1,2-diacylglycerol in IIC9 fibroblasts after stimulation with epidermal growth factor (EGF), and found that the mass of this lipid remained elevated for at least four hours. The concentration-dependence of EGF-stimulated 1,2-diacylglycerol production and [3H]thymidine incorporation were similar. Studies of phospholipid metabolism strongly suggested that phosphatidylcholine was the source of the 1,2-diacylglycerol generated in response to EGF. EGF did not stimulate the hydrolysis of other phospholipids, including the phosphoinositides, nor did it increase synthesis de novo of 1,2-diacylglycerol. This pattern of sustained 1,2-diacylglycerol formation from phosphatidylcholine may be important in the mitogenic signalling of EGF and potentially other growth factors.
Associative Data Structures

Massively parallel bit-serial SIMD computers such as the MMP* with 16K processors and the Connection Machinet† with 64K processors eliminate the need for time-sharing a single central processing unit with a multitude of data elements, thus avoiding the classic memory—CPU bottleneck. And although these machines were designed with the traditional data-addressing mechanisms, they can be programmed as associative computers, using massive parallel searching in place of address calculation, reducing data structure and programming complexity.
Two new genera of fungal trichomycetes, Bactromyces and Laculus (Harpellales), from Nova Scotia, Canada

The gut lumen of immature aquatic insects is colonized by a unique community of protistan and fungal organisms, collectively called trichomycetes. The species diversity of fungal trichomycetes appears to be high, with new taxa published regularly. Bactromyces fluminalis and Laculus insecticola, species belonging to two new genera of fungal trichomycetes, are described from stonefly and mayfly nymphs, respectively. Bactromyces fluminalis was collected from a stream habitat in Long Lake Provincial Park, Halifax, Nova Scotia, Canada, while Laculus insecticola was found in a lentic environment (Governor Lake) in Timberlea, Nova Scotia, a suburb within the Halifax Regional Municipality. In addition to these new taxa, a new species, Pteromaktron timberleaense, in this previously monotypic genus is described from the hindgut of a mayfly collected from a stream in Timberlea, Nova Scotia. This discovery makes new material available for study, since it appears the type specimen for this genus is lost.

Theology and Ethics Then, Now, and In-Between at Union Seminary and Elsewhere

The story of theology and ethics at Union Seminary from 1812 to the present illustrates the critical relationship between theology, ethics, and historical circumstances. In a distinctive fashion, it also reflects both the wider story and current challenges of theology and ethics in American Protestantism.
The Achievement of High Statuses and Leadership in the Small Group

T THIS paper has three purposes: to develop an approach to the study of intragroup status achievement and leadership which focuses primarily upon the group itself and only secondarily upon the individual members and their personal characteristics; to summarize an application of this approach in a larger study conducted by the writer, which seeks to advance hypotheses concerning the techniques or methods by which the constituent statuses of group structure are achieved by the membership; and to indicate the implications involved for sociological theory and research.
Caprock Fracture Dissolution and CO2 Leakage

Caprocks are impermeable sedimentary formations that overlie prospective geologic CO2 storage reservoirs. As such, caprocks will be relied upon to trap CO2 and prevent vertical fluid migration and leakage. Natural and industrial analogues provide evidence of long-term performance of caprocks in holding buoyant fluids. However, the large volumes of CO2 that must be injected and stored to meaningfully reduce anthropogenic greenhouse gas emissions will exert unprecedented geomechanical and geochemical burdens on caprock formations due to elevated formation pressures and brine acidification. Caprocks have inherent vulnerabilities in that wellbores, faults and fractures that transect caprock formations may provide conduits for CO2 and/or brine to leak out of the intended storage formation. As a result, a critical criterion for CO2 storage reservoir siting assessments will be to predict and reliably quantify the risk of leakage through caprock formations. We use “flow paths” as a catchall term for any fluid conduit through caprocks including pore networks, fractures and faults along with any combination of the three elements. It is useful to assess leakage rates through flow paths in terms of their individual transmissivity, T [m4], which is the product of the permeability and the cross-sectional area of the flow path. Darcy’s law can be used to relate these intrinsic flow path characteristics and the hydraulic potential (pressure) gradient to determine a volumetric flow rate, Q , or a leakage rate for the individual flow path: ![Formula][1] (1) Where P is the hydraulic potential [Pa], z is the depth [m], μ is the fluid viscosity [Pa s] and A [m2] is the cross-sectional area of the flow path perpendicular to flow, and A equals the product of average fracture aperture and fracture length normal to the flow direction. Predicting leakage potential, however, is extremely complex because assessments … [1]: /embed/mml-math-1.gif
International Organizations and the Rule of Law

International rule of law fixes should take into full account the special features of the existing international legal system, including, as noted, its reliance on contested, iterative interactions among diverse political and legal forums. Those arguing that the rule of law requires the Security Council to replace its ombudsperson mechanism with a full scale international court to implement its smart sanctions need to consider whether this is the best prescription, as opposed to, for example, insisting that an ombudsperson procedure apply to all Security Council sanctions committees and not just to those sanctions committees that deal with ISIL and Al-Qaida. Sober reflection on whether a full scale judicial process is truly needed is a good idea not only because insistence on the perfect rule of law ideal may be the enemy of the good. It is a good idea because nuance is needed when examining what the national rule of law truly requires and when exporting national rule of law recipes to the international realm.
Sexual Behavior and Knowledge among Adolescents with Perinatally Acquired Human Immunodeficiency Virus Infection Compared to HIV-Uninfected Adolescents at an Urban Tertiary Center in New Jersey.

Background. Sexual behaviors and knowledge among PHIV-infected (PHIV(+)) adolescents in comparison with HIV-uninfected youths are not well understood and continue to be studied actively. Objective. To compare sexual behavior and sexual knowledge of PHIV(+) and HIV-uninfected adolescents at an urban, tertiary-care center in New Jersey. Study Design. Modified Centers for Disease Control and Prevention (CDC) Youth Risk Behavior Surveillance questionnaire was administered to PHIV(+) and HIV-uninfected adolescents to assess and compare sexual behavior and knowledge over a 1-year-period. Results. Twenty-seven PHIV(+) and 100 HIV-uninfected adolescents were studied; 59% PHIV(+) and 52% HIV-uninfected adolescents were sexually active. A significantly higher proportion of PHIV(+) adolescents compared to HIV-uninfected adolescents reported ≥1 occasion of unprotected penetrative sex (p 4) sexual partners (p = 0.037). Significantly more PHIV(+) males reported receptive anal intercourse (p 80% adolescents in both groups did not consider multiple sexual partners a risk factor for HIV transmission. Only 25% PHIV(+) adolescents reported disclosing their seropositive status to their first sexual partners. Conclusions. High risk sexual behaviors were significantly more prevalent among PHIV(+) youths; however both groups demonstrated considerable gaps in sexual knowledge. There is an urgent need for heightening awareness about risky behaviors, interventions for prevention, and reproductive health promotion among adolescents.
Exploring trends of nonmedical use of prescription drugs and polydrug abuse in the Twittersphere using unsupervised machine learning.

Abstract Introduction Nonmedical use of prescription medications/drugs (NMUPD) is a serious public health threat, particularly in relation to the prescription opioid analgesics abuse epidemic. While attention to this problem has been growing, there remains an urgent need to develop novel strategies in the field of “digital epidemiology” to better identify, analyze and understand trends in NMUPD behavior. Methods We conducted surveillance of the popular microblogging site Twitter by collecting 11 million tweets filtered for three commonly abused prescription opioid analgesic drugs Percocet® (acetaminophen/oxycodone), OxyContin® (oxycodone), and Oxycodone. Unsupervised machine learning was applied on the subset of tweets for each analgesic drug to discover underlying latent themes regarding risk behavior. A two-step process of obtaining themes, and filtering out unwanted tweets was carried out in three subsequent rounds of machine learning. Results Using this methodology, 2.3M tweets were identified that contained content relevant to analgesic NMUPD. The underlying themes were identified for each drug and the most representative tweets of each theme were annotated for NMUPD behavioral risk factors. The primary themes identified evidence high levels of social media discussion about polydrug abuse on Twitter. This included specific mention of various polydrug combinations including use of other classes of prescription drugs, and illicit drug abuse. Conclusions This study presents a methodology to filter Twitter content for NMUPD behavior, while also identifying underlying themes with minimal human intervention. Results from the study track accurately with the inclusion/exclusion criteria used to isolate NMUPD-related risk behaviors of interest and also provides insight on NMUPD behavior that has a high level of social media engagement. Results suggest that this could be a viable methodology for use in big data substance abuse surveillance, data collection, and analysis in comparison to other studies that rely upon content analysis and human coding schemes.

“Simple” and “double” applicatives in Shiwilu (Kawapanan)

Shiwilu (Kawapanan, Peru) exhibits a prolific applicative system that comprises seven constructions involving distinct affixes. The present article offers the first account of this feature. In so doing, it seeks to expand our typological knowledge of linguistic systems with multiple applicative constructions and shed light onto the ways applicative constructions relate to word derivation. The suffix -tu is particularly intriguing. It modifies the verb valency by either adding or suppressing an object, depending on the base to which it attaches. Comparable affixes that perform these seemingly opposite functions are found in other languages of the world (see instances of applicative / antipassive polysemy, Malchukov, ms.). What makes Shiwilu special is that -tu is also required in certain types of applicative constructions simultaneously to the dedicated applicative. This double derivation strategy has not been reported for other languages of the region and is unattested in Shawi, Shiwilu’s only sister language.
Antenna Placement for MIMO Localization Systems With Varying Quality of Receiver Hardware Elements

This letter considers localization using multiple-input multiple-output (MIMO) systems, configured with multiple transmit and receive sensors, widely distributed in a three-dimensional space. The placement of antennas is explored when the receiver hardware has varying noise quality. Cramer–Rao Lower Bounds are optimized to find the antenna placements, where it is shown that a symmetric configuration of transmitting and different quality receiving sensors around an emitter is optimal.
“They Died the Spartan’s Death”: Thermopylae, the Alamo, and the Mirrors of Classical Analogy

ABSTRACTIn moments of crisis, people often make sense of the present by activating memories of the past through particular tropes of public memory. Classical analogies are one such trope, suggesting a sense of continuity between a (seemingly) stable ancient world and a chaotic present. Despite their prominence in American rhetoric, classical analogies have received too little attention from scholars of rhetoric. In the following, I interrogate the use of classical analogies in nineteenth-century American rhetoric— a period in which the classics were a vibrant aspect of public culture—by analyzing analogies between the fall of the Alamo and the fifth-century BC battle of Thermopylae. Thermopylae analogies were activated as tropes of public memory to warrant the formation of a defiant political identity for a Texian community reeling from defeat. Through an analysis of key texts that utilized Thermopylae analogies, I show that classical analogies sometimes go beyond comparisons between the past and the pres...
From compliance to self-regulation: Development during early childhood

This study examined the development of self-regulation during early childhood and the reciprocal relations between self-regulation and maternal sensitivity. Data (N = 1,364) were drawn from the NICHD Study of Early Child Care and Youth Development (NICHD SECCYD). Children's situational and committed compliance were assessed in the laboratory at 24 and 36 months, delay of gratification at 54 months, self-control at 54 months and kindergarten age, and maternal sensitivity was observed at 24, 36, and 54 months. Self-regulation was characterized to progress from situational compliance to committed compliance and then to fully self-motivated regulation. Findings also suggest that the development of self-regulation reflects an ongoing transactional process in which child self-regulation and maternal sensitivity mutually influence each other.
Infectious Sex? An Autoethnographic Exploration of HIV Prevention

In this queer autoethnography, I track the development of HIV prevention and sex in my life. I delve into the era before HIV infection, after my HIV diagnosis, and then again with the knowledge that my HIV is stable and not infectious. These eras point to the creative ways that individuals and communities construct sex lives around HIV narratives. Rather than static equations of risk and actions, HIV prevention could be considered a dynamic process. Through this study, I map out dialogue that must continue to happen about sex and substance use, within the LGBT community and the HIV community.
New Precision Orbits of Bright Double-lined Spectroscopic Binaries. X. HD 96511, HR 7578, and KZ Andromedae

From an extensive number of newly acquired radial velocities we determine the orbital elements for three late-type dwarf systems, HD 96511, HR 7578, and KZ And. The orbital periods are 18.89737 ± 0.00002, 46.81610 ± 0.00006, and 3.0329113 ± 0.0000005 days, respectively, and all three systems are eccentric, although KZ And is just barely so. We have detected lines of the secondary of HD 96511 for the first time. The orbital dimensions (a 1 sin i and a 2 sin i) and minimum masses (m 1 sin3 i and m 2 sin3 i) of the binary components all have accuracies of 0.2% or better. Extensive photometry of the chromospherically active binary HR 7578 confirms a rather long rotation period of 16.446 ± 0.002 days and that the K3 V components do not eclipse. We have estimated the basic properties of the stars in the three systems and compared those results with evolutionary tracks. The results for KZ And that we computed with the revised Hipparcos parallax of van Leeuwen produce inconsistencies. That parallax appears to be too large, and so, instead, we used the original Hipparcos parallax of the common proper motion primary, which improves the results, although some problems remain.

An Ex Vivo Comparison of 2 Cyanoacrylate Skin Protectants.

Purpose The purpose of these experiments was to compare 2 commercially available skin protectants with different chemical compositions. Design Two materially different skin protectants were applied to ex vivo pig skin, subjected to stresses, and the resulting skin was observed and analyzed. Methods Using ex vivo pig skin, we sought to better understand the physical differences between a cyanoacrylate-based and a mixed cyanoacrylate/acrylic polymer-based skin protectant. A combination of imaging techniques and microscopic analyses was used to observe and quantify differences in layer thickness and the degree of steadfastness of the layers to liquid stresses. Results The experiments revealed that the solely cyanoacrylate-based protectant created a layer that was, on average, 5.1 times thicker than the mixed polymer product (p= 1.8 × 10). Observation via electron microscopy also revealed that the extent of coverage varied between the 2 products. In a final experiment, we observed that the mixed polymer product maintained a high degree of adhesiveness, which led to the removal of sheets of epithelium upon gentle blotting. Conclusions The experiments revealed that while the 2 skin protectants share a common ingredient, both the quantity of that ingredient and the inclusion of other materials in one of them lead to substantially different properties when tested in the research setting.
An algorithm for optimal management of aggregated HVAC power demand using smart thermostats

Abstract This paper presents an algorithm for optimal management of aggregated power demand of a group of heating, ventilating and air-conditioning (HVAC) units. The algorithm provides an advanced direct load control mechanism for HVACs that leverages the availability of smart thermostats, which are remotely programmable and controllable. The paper provides a theoretical basis and an optimal solution to the problem of cycling a large number of HVAC units while respecting customer-chosen temperature limits for the purpose of maximum load reduction. The problem is presented in a new light by transforming it into a job scheduling problem and is solved using a combination of a novel greedy algorithm and a binary search algorithm. By leveraging widespread availability of smart internet-based (also referred to as IoT-based) thermostats in today’s environment, the proposed approach can be readily applied to residential buildings without additional electrical/IT infrastructure changes.
Symmetry-Protected Topological Metals.

We show that sharply defined topological quantum phase transitions are not limited to states of matter with gapped electronic spectra. Such transitions may also occur between two gapless metallic states both with extended Fermi surfaces. The transition is characterized by a discontinuous, but not quantized, jump in an off-diagonal transport coefficient. Its sharpness is protected by a symmetry, such as, e.g., particle-hole symmetry, which remains unbroken across the transition. We present a simple model of this phenomenon, based on 2D $p+ip$ superconductor with an applied supercurrent, and discuss its geometrical interpretation.

The Value of Serum Enzymatic Acid Phosphatase in the Staging of Localized Prostate Cancer

AbstractWith the development of reliable assays for the measurement of prostate specific antigen (PSA), the use of serum enzymatic acid phosphatase in the staging of disease before radical prostatectomy has been called into question. We evaluated 460 consecutive men who were referred to our institution as candidates for radical prostatectomy. Staging evaluation included digital rectal examination, serum measurements of enzymatic acid phosphatase and PSA, bone scans and, in patients in whom advanced clinical stage was anticipated, computerized tomography, magnetic resonance imaging or transrectal ultrasonography. Of the 460 men 21 (4.6%) had elevations of serum enzymatic acid phosphatase. All 19 men with elevations who were fully evaluated proved to have either positive bone scans, extraprostatic extension of disease, PSA greater than 100ng./ml., positive lymph nodes or positive seminal vesicles. However, in 17 of the 21 men (81%) with elevated serum enzymatic acid phosphatase advanced disease was detected...
The Hohenberg-Kohn Theorems and Kohn-Sham Density Functional Theory

Hohenberg-Kohn-Sham density functional theory in its approximate form is possibly the most extensively employed formalism for the determination of electronic structure in atomic and condensed matter physics, and in quantum chemistry. In this chapter we describe the in principle exact framework of the theory. We begin by explaining the two theorems of Hohenberg and Kohn (HK) [1]. These theorems then constitute the basis of Kohn-Sham density functional theory (KS-DFT) [2]. The precursor to the HK theorems and KS-DFT is comprised of the work of Thomas [3], Fermi [4], Dirac [5], von Weizsacker [6], and Slater [7]. For a description of the precursory material, and for the broader context of Hohenberg-Kohn-Sham density functional theory, the reader is referred to three excellent texts on the subject [8]–[10]. Slater theory will be described more fully in a later chapter.

Correctly Identifying Hospitalized Pediatric Patients With Tobacco Smoke Exposure: The First Step in Addressing Parental Tobacco Use.

In their study in this issue of Hospital Pediatrics , Mahabee-Gittens et al1 compared tobacco smoke exposure (TSE) based on parental self-report in a convenience sample of pediatric patients who were hospitalized with TSE based on biochemical confirmation with levels of child salivary cotinine, a biomarker of nicotine. The study revealed poor sensitivity and specificity of parental self-report of TSE (reported in the electronic health record [EHR]), compared with measured cotinine levels. Only 67% of patients with positive cotinine levels were identified as having TSE by parental self-report, as documented in the EHR. In contrast, 77% of children with parental report of TSE who were hospitalized had positive cotinine levels. The authors concluded that almost 40% of children were misclassified in the EHR as not …
A continuum of stomatal responses to water deficits among 17 wine grape cultivars (Vitis vinifera).

Vitis vinifera L. cultivars have been previously classified as isohydric, near-isohydric, anisohydric or isohydrodynamic, depending on the study. To test the hypothesis that V. vinifera cultivars’ stomatal behaviour can be separated into distinct classes, 17 cultivars grown in a replicated field trial were subjected to three irrigation treatments to manipulate vine water status across multiple years. Predawn (ΨPD) and midday (Ψl) leaf water potential and midday stomatal conductance (gs) were measured regularly throughout several seasons. The relationship of gs to Ψl was best modelled as a sigmoidal function and maximum stomatal conductance (gmax), water status at the onset of stomatal closure (Ψl95), sensitivity of closure (gsensitivity) and water status at the end of closure (Ψl25) were compared. There were no significant differences in gmax among cultivars. Cultivar-specific responses of gs to Ψl were broadly distributed along a continuum based on the relationship between Ψl95 and gsensitivity. Season-long cultivar mean Ψl values were positively related to Ψl25. In general, cultivars responded similarly to one another at high and low water status, but their stomatal behaviour differed at moderate water deficits. The results show that V. vinifera cultivars possess both iso- and anisohydric stomatal behaviours that depend on the intensity of water deficits, and call into question previous classifications assuming a single behaviour.
Real women have (just the right) curves: investigating anti-thin bias in college women.

Weight stigma is associated with negative mental and physical health outcomes across the body mass index (BMI) continuum. However, few studies have examined discrimination experienced by people with low body weights. This study explored the presence of anti-thin bias, defined as the belief that individuals at lower body weights have undesirable personality characteristics, in young adult women. Additionally, we examined perceived etiology of weight for women with underweight. Participants (N =295 women, age 18.84 ± 2.32) were randomly assigned to read one of the six vignettes about women who differed by race (White and Black) and BMI status (slightly underweight, average weight, and slightly overweight). Negative personality characteristics were more likely to be ascribed to vignette characters with under- or overweight BMIs, compared to characters with average weight BMIs. Participants were more likely to attribute underweight characters’ body weight to an eating disorder (ED) compared with average or overweight characters. Results suggest that women with under- or overweight BMIs experience greater stigmatization for their body weight than women with average BMIs, underscoring the need for research to investigate weight discrimination across the weight spectrum.
