The Return of Superman? Individual and Organizational Predictors of Men’s Housework in South Korea

In this survey study, we investigate factors that predict the extent of men’s engagement in housework in South Korea. Using data collected from 466 working fathers during the period from March 2013 to August 2013, it was found that a more egalitarian gender ideology and supervisor support for work–family balance were significant predictors of the frequency of men’s participation in housework (i.e., child-rearing activities and household chores), but that long work hours, which are prevalent in South Korea, moderated these relationships. More specifically, the condition of long average work hours reduced the positive effect of an egalitarian gender ideology and a supportive supervisor attitude on the extent of housework. Therefore, we contend that the effects of changes in individuals’ attitudes toward men’s housework will be limited without addressing cultural norms of overwork or “work devotion” in South Korea.
Establishing the micro foundations of a macro theory: information, movers, and the competitive local market for public goods

e Tiebout model of competition in the local market for public goods is an important and controversial theory. The current debate revolves around the apparent disparity between macro 5. X empirical studies that show greater efficiency in the supply of public goods in polycentric regions compared to consolidated ones and micro evidence of widespread citizen-consumer ignorance, which has been used to argue that individual actions cannot plausibly lead to efficiency-enhancing competition between local governments. We argue that competitive markets can be driven by a subset of informed consumers who shop around between alternate suppliers and produce pressure for competitive outcomes from which all consumers benefit. Using data from a survey of overfive hundred households, we analyze the role of these marginal citizen-consumers and incorporate the costs of information gathering and the strategic interests of local governments into the competitive market model.
Enhancing integrative motivation: The Japanese-American Collaborative Learning Project

AbstractThe Collaborative Learning Project is a language exchange program in which American and Japanese university students have the opportunity to interact with native speakers over the course of a three-week period. This paper reports the outcomes of the Collaborative Learning Project in terms of its effectiveness in fulfilling student expectations and their integrative motivation, i.e. social and cultural motivation. Using quantitative and qualitative data, this research includes the first project (2012) as a preliminary study, and the second project (2013) as the basis of the formative assessment. In their responses to questionnaires, the majority of the students reported that the program fulfilled their expectations and fostered their integrative motivation. After participating in the project, the participants were motivated to continue learning Japanese and seemed to be more interested in the study abroad program/studying abroad.

The use of chromosomal microarray for prenatal diagnosis.

Chromosomal microarray analysis is a high-resolution, whole-genome technique used to identify chromosomal abnormalities, including those detected by conventional cytogenetic techniques, as well as small submicroscopic deletions and duplications referred to as copy number variants. Because chromosomal microarray analysis has a greater resolution than conventional karyotyping, it can detect deletions and duplications down to a 50- to 100-kb level. The purpose of this document is to discuss the technique, advantages, and disadvantages of chromosomal microarray analysis and its indications and limitations. We recommend the following: (1) that chromosomal microarray analysis be offered when genetic analysis is performed in cases with fetal structural anomalies and/or stillbirth and replaces the need for fetal karyotype in these cases (GRADE 1A); (2) that providers discuss the benefits and limitations of chromosomal microarray analysis and conventional karyotype with patients who are considering amniocentesis and chorionic villus sampling (CVS), and that both options should be available to women who choose to undergo diagnostic testing (GRADE 1B); (3) that pre- and posttest counseling should be performed by trained genetic counselors, geneticists, or other providers with expertise in the complexities of interpreting chromosomal microarray analysis results (Best Practice); (4) that patients be informed that chromosomal microarray analysis does not detect every genetic disease or syndrome and specifically does not detect autosomal-recessive disorders associated with single gene point mutations, as well as that chromosomal microarray analysis can detect consanguinity and nonpaternity in some cases (Best Practice); (5) that patients in whom a fetal variant of uncertain significance is detected by prenatal diagnosis receive counseling from experts who have access to databases that provide updated information concerning genotype-phenotype correlations (Best Practice).
A key management architecture and protocols for secure smart grid communications

Providing encrypted communications among power grid components is expected to be a basic requirement of smart grid systems in the future. Here, we propose a key management architecture and associated protocols tailored to support encrypted smart grid communications. The architecture consists of two levels structured around the grid control system hierarchy. At the top level, which consist of control centers and regional coordinators, a bottom-up key structure is adopted using hash chaining and a logical key hierarchy. The lower level of the architecture consists of the regional coordinators i.e., substations and distribution systems and remote ends e.g., meters and pole-top sensors and utilizes a top-down key management approach built on an inverse element method. The proposed key management schema supports the hierarchical structure of the smart grid control mechanisms, and it takes the resource and electronic/physical security differences of the control levels into account. We define a set of protocols utilizing the architecture to provide secure unicast, multicast, and broadcast communications. Furthermore, we illustrate how the architecture is flexible enough to easily handle power grid nodes joining and leaving the system at the different levels. Lastly, we compare the proposed schema with existing ones and show that our architecture can achieve efficient key management to provide secure communications.

Vapor-phase polymerized poly(3,4-ethylenedioxythiophene) (PEDOT)/TiO2 composite fibers as electrode materials for supercapacitors

Abstract Vapor-phase polymerized poly(3,4-ethylenedioxythiophene) (PEDOT)/TiO2 composite fibers were fabricated and applied as the supercapacitor electrode materials. TiO2 fibers were prepared as substrates for the vapor-phase polymerization process, by electrospinning and calcination in air. The symmetric supercapacitor cells assembled with the resulting composites were studied by a series of electrical measurements including cyclic voltammetry, charge-discharge characterization and electrochemical impedance spectroscopy. To further understand the capacitive behavior, the band gap energy of the composite fibers and the specific surface area of TiO2 fibers calcined at varied temperatures were measured. The highest specific capacitance of PEDOT on TiO2 fibers to date, 87.9 F g−1, was achieved with the composite fibers prepared by vapor-phase polymerization at 50 °C on the TiO2 fibers calcined at 550 °C. The pseudocapacitance and the reversibility of PEDOT were improved in comparison to other PEDOT/TiO2 binary composites.
A double-lithography and double-reflow process and application to multi-pitch multi-height mechanical flexible interconnects

Wafer-level multi-pitch and multi-height mechanically flexible interconnects (MPMH MFIs) are demonstrated using a double-lithography and double-reflow process of a large array of sacrificial polymer domes with various heights (ranging from 26 µm to 66 µm). Using these domes, NiW MFIs with various pitches (ranging from 50 µm to 150 µm) are formed atop the multi-height domes using electroplating. The mechanical and electrical properties of the fabricated MPMH MFIs are characterized using indentation and four-point resistance measurements.
The People Who Discovered Columbus: The Prehistory of the Bahamas

For the Lucayan Arawaks of the Caribbean, the year 1492 marked the beginning of the end: the first people contacted by Christopher Columbus were the first extinguished. Within 30 years, a population of perhaps 80,000 had declined to, at most, a few refugees. Clearing new ground in the study of prehistoric societies, Keegan argues that a different perspective on the past provides an accurate portrait of a culture that became extinct almost 500 years ago. Keegan terms his approach palaeoethnography, developing a portrait of the past by linking archaeological field data and historical documents. The result, an overview of the prehistory of the Bahamas, explains how and why the Bahamas were colonised by the Tainos almost 1,400 years ago. The portrait includes characteristics of the islands themselves, descriptions of how the Lucayans made their settlements, what they ate, how they organised in social groups, and how their population spread throughout the archipelago. Keegan reconstructs Columbus' voyage through the West Indies, raising questions about the explorer's motivations and presenting a controversial theory about where, exactly, Columbus landed. Offering new perspectives on Caribbean prehistory to both scholars and general readers, the book ends with the Spaniards' arrival and the Lucayans' demise.
Modification of the Orthosteric PPARγ Covalent Antagonist Scaffold Yields an Improved Dual-Site Allosteric Inhibitor.

GW9662 and T0070907 are widely used commercially available irreversible antagonists of peroxisome proliferator-activated receptor gamma (PPARγ). These antagonists covalently modify Cys285 located in an orthosteric ligand-binding pocket embedded in the PPARγ ligand-binding domain and are used to block binding of other ligands. However, we recently identified an alternate/allosteric ligand-binding site in the PPARγ LBD to which ligand binding is not inhibited by these orthosteric covalent antagonists. Here, we developed a series of analogs based on the orthosteric covalent antagonist scaffold with the goal of inhibiting both orthosteric and allosteric cellular activation of PPARγ by MRL20, an orthosteric agonist that also binds to an allosteric site. Our efforts resulted in the identification of SR16832 (compound 22), which functions as a dual-site covalent inhibitor of PPARγ transcription by PPARγ-binding ligands. Molecular modeling, protein NMR spectroscopy structural analysis, and biochemical assays indi...
On Gratitude, for My Father

Analysis of Variance with two Factors

Often we have several factors that we need to simultaneously compare. For example, both the color and style of a package might influence potential customers, and we would like to make sure that we choose the right combination. The problem of choosing the right combination is made more difficult because such factors often interact. In this example, the best color for one style of package might be the worst color for a different style. Two-way analysis of variance with interactions permits one to resolve these issues when only two grouping factors are involved. More complicated analysis methods generalize this approach to problems with three or more factors. Indeed, regression analysis can be used to obtain the results for any type of anova problem, albeit the results will be tedious to sort out.
Understanding the Characteristics of Mobile Augmented Reality Applications

Recently, augmented reality technologies are debuting to the mainstream markets. Currently, smartphones are still the dominant computing platform for providing mobile augmented reality (MAR) experience to users. Nevertheless, MAR on smartphones faces some key challenges as the rich functionalities increase concerns including battery power drain and thermal dissipation. This paper takes the first step to understand the characteristics of MAR apps from the system and architecture perspectives. We observe that MAR apps exhibit much higher Thread-level Parallelism (TLP) and have a potential to better exploit the big.LITTLE architecture. We further build Multi-comPonent Power and Thermal Analysis Tool (MPPTAT) on Android mobile platform to break down the power consumption and thermal dissipation into hardware components, threads, and phases. Power characterization shows that MAR apps exhibit higher energy consumption compared to other popular mobile non-MAR apps, mainly contributed by the camera. Thread level breakdown shows that the major CPU power consumption is MediaServer, which controls the camera to capture and process multimedia information on smartphones. We also investigate the impact of DVFS, and results indicate that current MAR apps' implementations are mostly CPU intensive and the mobile GPU is not well exploited yet. Moreover, thermal characterization shows that compared to the non-MAR apps, the frequent usage of the camera not only increases the temperature of the camera module but also dissipates the heat to other layers, which directly affect user experience. We believe that our work reveals insights for software and hardware designers to fine-tune augmented reality workloads on mobile platforms.
Liquefacation of Silty Soils

Liquefaction during earthquakes has been a significant cause of failure of onshore as well as offshore structures. The phenomenon of liquefaction has been studied extensively for the case of cohesionless soils. Finegrained soils, such as silts and sands with fines, have generally been considered non-liquefiable in the past. Recent studies have shown that finegrained soils in certain situations may be susceptible to liquefaction. This paper presents the results of an experimental investigation conducted to determine the liquefaction susceptibility of a low-plasticity silty soil. Cyclic triaxial tests were conducted on undisturbed and reconstituted specimens for this purpose. The results of the study indicate that low-plasticity specimens used in this test program were susceptible to failure by large axial deformations even though liquefaction defined in terms of loss of initial effective confining pressure may not occur.
Viral Hemorrhagic Fevers

Viral hemorrhagic fevers (VHF) are acute febrile viral infectious diseases of humans, characterized by multisystem involvement and evidence of microvascular leak, with or without hemorrhage. This clinical syndrome is associated with more than 20 viruses, all of which are lipidenveloped viruses with RNA genomes. VHF are all zoonoses, in which human beings are accidental or dead-end hosts. Specifi c VHF differ in terms of clinical, epidemiological, and pathologic features. In most VHF, the lung is involved as part of the systemic manifestations of cardiovascular, coagulation, or infl ammatory disturbances. Hantavirus pulmonary syndrome is an example of a VHF in which pulmonary involvement is the primary contributor to clinical disease.
Effect of Surrounding Tissue-Mimicking Gelatin in the Mechanical Properties of Arteries

Arterial elasticity has become an important predictor of cardiovascular diseases and mortality. Pulse wave velocity (PWV) is the most widely used method despite its disadvantages, which have prevented this technique from becoming a clinical tool. In our laboratory we have developed an ultrasound radiation force based technique to generate mechanical waves in the arterial wall. The speed and modes of propagation of these induced waves are used to estimate the mechanical properties of the vessel wall. In this work, we present a study done on excised carotid arteries from 8 healthy, young pigs. We compared the effect of surrounding tissuemimicking gelatin on the elasticity properties by testing the arteries embedded and not embedded in the gelatin as an evaluation of the effects of surround tissue. We also evaluated the effect of stretch on the Young’s modulus but changing the prestretch in the artery at 3 different levels. The results showed that there was little difference in the Young’s modulus of the arteries when loaded with or without gelatin. The Young’s modulus increased from 80 kPa at 10 mmHg to 160 kPa at 100 mmHg. The levels of stretch significantly changed the behavior of the Young’s modulus with pressure, for 7 cm stretch the modulus increased from 81 kPa at 10 mmHg to 192 kPa at 100 mmHg; for 8 cm, the modulus increased from 120 to 367 kPa and for the 9 cm stretch in increased from 623 to 734 kPa. This technique has the potential to study the mechanical properties of the arterial wall in a noninvasive, quantitative and reproducible manner. We showed that the loading of soft tissue around the arteries does not change significantly the mechanical properties, while the level of stretch plays a significant role.
Legal Update: Where the Lawsuits Are

The legal drama has always been a popular television staple. From Perry Mason to L.A. Law to Boston Legal these shows feature fast-moving, hard driving lawyers who resolve their clients’ legal challenges in the space of an hour. Most of us know that the legal process takes more than an hour. But even real programming like Court TV or the O.J. Simpson trials don’t show the legal process at its most complex. While the Simpson trial went on for several weeks, there was a fairly clear-cut beginning (the Bronco chase), middle (Johnny Cochran and Judge Ito) and end (acquittal), over a fairly limited time frame of a few months. But lawsuits involving business or commercial interests are often conducted not over a period of months, but over a period of years. All three stages: beginning, middle and end, are often very protracted. The parties to the lawsuit generally expect that kind of time-frame. In some cases, they may even welcome it, or at least strategically plan for it. But for those outside of the lawsuit whose interests may be affected by the outcome, the wait can become confusing and frustrating.
An Update on Therapeutics: The Cancer Anorexia/Weight Loss Syndrome in Advanced Cancer Patients

Experienced oncologists acknowledge that the cancer anorexia/weight loss syndrome predicts a shorter survival for patients with advanced, incurable disease. Several powerful, well-conducted studies have borne out this clinical impression. DeWys et al. focused on weight loss in a multiinstitutional, retrospective review of 3047 cancer patients and observed that loss of more than 5% of premorbid weight predicted an early demise [1]. This prognostic effect occurred independently of tumour stage, tumour histology and patient performance status. Weight loss was also associated with a trend towards lower chemotherapy response rates.
Ultrastructure of picosecond laser intrastromal photodisruption

Purpose To investigate the ultrastructure of the corneal stroma after picosecond intrastromal photodisruption with a neodymium-doped yttrium-lithium-fluoride (Nd:YLF) laser. Methods We performed picosecond intrastromal photodisruption on six human eye-bank eyes using a lamellar technique. Thirty picosecond pulses at 1000 Hz and 20 to 25 mJ per pulse were placed in an expanding spiral pattern, the pulses separated by 15 microns. Three layers were placed in the anterior stroma, separated from each other by 15 microns. In addition, intrastromal radial and arcuate incisions were generated in two living rabbit eyes in a plane perpendicular to the corneal surface. After the procedure, the corneas were processed for scanning and transmission electron microscopy. Results Scanning electron microscopy of the eye-bank eyes demonstrated multiple, coalescing intrastromal cavities forming a layer oriented parallel to the corneal surface. These cavities had smooth inner walls. Transmission electron microscopy demonstrated tissue loss surrounding some cavities, with the terminated ends of collagen fibrils clearly evident. Other cavities were formed by separation of lamellae, with little evidence of tissue loss. A pseudomembrane was present along the margin of some cavities. Although there was occasional underlying tissue disruption along the border of a cavity, there was no evidence of thermal damage or tissue necrosis. The perpendicular photodisruptions demonstrated intrastromal cleavage of corneal collagen similar to diamond-knife incisions, with the exception of intact overlying Bowman's and epithelial layers. Conclusion Intrastromal photodisruption with a Nd:YLF picosecond laser induced no thermal necrosis or coagulative change in the region of tissue interaction. Lamellar intrastromal photodisruption demonstrated both tissue loss and lamellar separation when performed with the current treatment parameters, possibly limiting ablation efficiency and predictability.
Behavioral, Psychopharmacological, and Neurochemical Effects of Chronic Neuroleptic Treatment during Development

Exposure to psychoactive drugs early in life may produce long-term alterations in the behavior of an organism resulting from subtle changes in the ultrastructure of the nervous system even in the absence of gross structural malformations. Chronic administration of neuroleptic drugs to laboratory animals early in ontogeny appears to induce such neurobehavioral teratogenic effects without precipitating gross congenital malformations. Although it appears from the clinical literature that neuroleptics do not produce gross congenital malformations, the potential neurobehavioral teratogenic effects of these substances on human offspring have not been systematically assessed in clinical populations (Goldberg & DiMascio, 1978). Yet, neuroleptics are frequently prescribed as antipsychotics and are even used as antiemetics in obstetrics (Goldberg & DiMascio, 1978).
THE SCOTOPIC AND PHOTOPIC BAR-PATTERN ERG - CONTRIBUTIONS OF THE CENTRAL AND PERIPHERAL RETINA *

The alternating phase bar-pattern ERG is used to investigate the contribution of specific retinal areas and specific retinal components to the ERG. Photopic and scotopic bar-pattern ERG’s are recorded under proper lighting conditions. The photopic ERG response is found to be proportional to the number of cones in the retinal area stimulated out to 18° from fixation and not to the total number of receptors.
What Next? A Heuristic Approach to Revitalizing the Contract Disputes Act of 1978

This essay, included in a 1999 special issue examining the Contract Disputes Act (CDA) of 1978 at its twentieth anniversary, begins from the premise that the statute's critics have valid reason to perceive that the CDA fails to provide a "fair and balanced system of administrative and judicial procedures for the settlement of claims and disputes." The essay suggests a framework for a meaningful debate over what an improved and invigorated CDA should look like but, in the end, raises more questions than it answers. Its purpose is heuristic; to frame a debate (which many feel is long overdue) as to what the CDA should do and how it should do so. It introduces a then-recent effort to articulate core principles for government procurement dispute resolution, then deems the effort an unsatisfactory platform for heuristic analysis. It attempts to determine the necessity for a dispute resolution statute and suggests that the fundamental purpose for such legislation is no more than to waive the Federal Government's immunity from suit. The essay then turns to the breadth of an appropriate waiver. Finally, it examines a number of issues, such as the nature of judicial and administrative fora and the certification requirement, that permeate our present system. The essay concludes by suggesting, at very least, that we should ask the difficult questions.
Speeding Ahead to a Better Place

In mid-2008, Shai Agassi, CEO of Better Place, is in the midst of planning a paradigm shift in clean transportation. In an attempt to wean the world from using gasoline-powered vehicles, his company is playing the role of innovator and integrator for new vehicles, charging spots, and battery switch stations. The effort also requires aligning various parties, from governments to auto manufacturers to consumers. The fledgling company has made good progress in both Israel and Denmark as the first two launch locations but faces a series of decisions on the best course of action going forward. Agassi must decide how best to market in these two countries given the likely adoption challenges once the infrastructure and cars are ready, as well as decide how quickly to begin pursuing other countries (and if so, which ones). A big part of the Better Place solution relies on a novel business model that needs to be evaluated for its attractiveness and feasibility. Learning Objective: To understand the challenges and opportunities inherent in creating a paradigm shift in an industry through innovative products, services, and business models.
Novelties in treatment of locally advanced rectal cancer.

Treatment of locally advanced rectal cancer is evolving through surgical innovation and paradigm shifts in neoadjuvant treatment. Whereas local recurrence was a significant concern before the systematic implementation of neoadjuvant chemoradiation therapy and surgery according to total mesorectal excision principles, distant relapse remains a major drawback. Hence, efforts in recent years have focused on delivering preoperative chemotherapy regimens to overcome compliance issues with adjuvant administration. In parallel, new surgical techniques, including transanal video-assisted total mesorectal excision and robot-assisted surgery, emerged to face the challenge to navigate in the deep and narrow spaces of the pelvis. Furthermore, patients experiencing a complete response after neoadjuvant treatment might even escape surgery within a close surveillance strategy. This novel “watch and wait” concept has gained interest to improve quality of life in highly selected patients. This review summarizes recent evidence and controversies and provides an overview on timely and innovative aspects in the treatment of locally advanced rectal cancer.

Operational Aspects of a Clinical Decision Support Program

Clinical decision support tools that involve improving test utilization should be jointly overseen by a laboratory stewardship committee and the hospital informatics team. The roles of these groups vary by institution and may overlap. This is a team effort and collaboration is a must. The effectiveness of these efforts in an institution depends on the receptiveness of leadership and providers, as well as the effectiveness of the associated committees. Examples of the challenges and successes of laboratory stewardship interventions that have been operationalized at the Cleveland Clinic that use clinical decision support tools, as well as associated literature, are reviewed.
Oxidation of Phosphines by Supercritical Nitrous Oxide

Despite its reputation for lack of reactivity at moderate temperatures, nitrous oxide is capable of oxidizing at least one class of organic compounds, the phosphines, at temperatures at or below 100 °C. The use of supercritical N2O as both the solvent and the reactant simplifies the isolation of the products and allows one to avoid the use of flammable liquid solvents.
Search for the Top Quark at D0 using Multivariate Methods

We report on the search for the top quark in proton-antiproton collisions at the Fermilab Tevatron in the di-lepton and lepton+jets channels using multivariate methods. An H-matrix analysis of the e-mu data corresponding to an integrated luminosity of about 13.5 pb-1 yields one event with a likelihood to be a top event (assuming top mass of 180 GeV/c**2) that is 10 times more than WW and 18 times more than Z -> tau tau. A neural network analysis of e+jets channel with about 48 pb-1 of data shows an excess of events in the signal region and yields a cross-section for top-antitop production of 6.7 +/- 2.3(stat.) pb, assuming a top mass of 200 GeV/c**2. A PDE analysis of e+jets data gives results consistent with the above.
Testing and confidence intervals for high dimensional proportional hazards models

Summary The paper considers the problem of hypothesis testing and confidence intervals in high dimensional proportional hazards models. Motivated by a geometric projection principle, we propose a unified likelihood ratio inferential framework, including score, Wald and partial likelihood ratio statistics for hypothesis testing. Without assuming model selection consistency, we derive the asymptotic distributions of these test statistics, establish their semiparametric optimality and conduct power analysis under Pitman alternatives. We also develop new procedures to construct pointwise confidence intervals for the baseline hazard function and conditional hazard function. Simulation studies show that all tests proposed perform well in controlling type I errors. Moreover, the partial likelihood ratio test is empirically more powerful than the other tests. The methods proposed are illustrated by an example of a gene expression data set.
Physiological assessment of non–target site restistance in multiple-resistant junglerice (Echinochloa colona)

Herbicide-resistant Echinochloa species are among the most problematic weeds in agricultural crops globally. Recurring herbicide selection pressure in the absence of diverse management practices has resulted in greater than 20% of sampled Echinochloa populations from rice (Oryza sativa L.) fields demonstrating multiple resistance to herbicides in Arkansas, USA. We assessed the resistance profile and potential mechanisms of resistance in a multiple herbicide–resistant junglerice [Echinochloa colona (L.) Link] (ECO-R) population. Whole-plant and laboratory bioassays were conducted to identify the potential mechanisms of non–target site resistance in this population. ECO-R was highly resistant to propanil (>37,800 g ha−1) and quinclorac (>17,920 g ha−1) and had elevated tolerance to cyhalofop (R/S = 1.9) and glufosinate (R/S = 1.2) compared to the susceptible standard. The addition of glufosinate (590 g ha−1) to cyhalofop (314 g ha−1), propanil (4,500 g ha−1), or quinclorac (560 g ha−1) controlled ECO-R 100%. However, cyhalofop applied with propanil (48% control) or quinclorac (15% control) was antagonistic. The application of the known metabolic enzyme inhibitors malathion, carbaryl, and piperonyl butoxide increased control of ECO-R with propanil (>75%) but not with other herbicides. Neither absorption nor translocation of [14C]cyhalofop or propanil was different between ECO-R and ECO-S. [14C]Quinclorac absorption was also similar between ECO-R and ECO-S; however, translocation of quinclorac into tissues above the treated leaf of ECO-R was >20% higher than that in ECO-S. The abundance of metabolites was higher (∼10%) in the treated leaves of ECO-R than in ECO-S beginning 48 h after treatment. The activity of β-cyanoalanine synthase, which detoxifies hydrogen cyanide, was not different between ECO-R and ECO-S following quinclorac treatment. Resistance to propanil was due to herbicide detoxification by metabolic enzymes. Resistance to quinclorac was due to a detoxification mechanism yet to be understood. The reduction in sensitivity to cyhalofop and glufosinate might be a secondary effect of the mechanisms conferring high resistance to propanil and quinclorac.
Computer-Assisted Analysis of the EPR Spectrum of Cu2+ :ZnF2

The EPR spectrum of a Cu2+ -doped single crystal of zinc fluoride has been measured at X band. This was done by utilizing a laboratory automation system for the IBM 1800 by which we are able to control the experimental observations and obtain improved results. Other computer programs were applied to analyze the spectra for the magnetic parameters, i.e., the g values, the copper hyperfine structure constants, and the fluorine superhyperfine structure constants. Covalency measures were then derived from these values. The details of the spectrum and its analysis, the laboratory automation system, and the covalency parameters compared with other copper compounds will be discussed.
Emergent unitarity in de Sitter from matrix integrals

We study Jackiw-Teitelboim gravity with positive cosmological constant as a model for de Sitter quantum gravity. We focus on the quantum mechanics of the model at past and future infinity. There is a Hilbert space of asymptotic states and an infinite-time evolution operator between the far past and far future. This evolution is not unitary, although we find that it acts unitarily on a subspace up to non-perturbative corrections. These corrections come from processes which involve changes in the spatial topology, including the nucleation of baby universes. There is significant evidence that this 1+1 dimensional model is dual to a 0+0 dimensional matrix integral in the double-scaled limit. So the bulk quantum mechanics, including the Hilbert space and approximately unitary evolution, emerge from a classical integral. We find that this emergence is a robust consequence of the level repulsion of eigenvalues along with the double scaling limit, and so is rather universal in random matrix theory.
On The Behavior of Delay Network Reverberator Modes

The mixing matrix of a Feedback Delay Network (FDN) reverberator is used to control the mixing time and echo density profile. In this work, we investigate the effect of the mixing matrix on the modes (poles) of the FDN with the goal of using this information to better design the various FDN parameters. We find the modal decomposition of delay network reverberators using a state space formulation, showing how modes of the system can be extracted by eigenvalue decomposition of the state transition matrix. These modes, and subsequently the FDN parameters, can be designed to mimic the modes in an actual room. We introduce a parameterized orthonormal mixing matrix which can be continuously varied from identity to Hadamard. We also study how continuously varying diffusion in the mixing matrix affects the damping and frequency of these modes. We observe that modes approach each other in damping and then deflect in frequency as the mixing matrix changes from identity to Hadamard. We also quantify the perceptual effect of increasing mixing by calculating the normalized echo density (NED) of the FDN impulse responses over time.
Consumption of the Total Western Diet Promotes Colitis and Inflammation-Associated Colorectal Cancer in Mice.

Consumption of a Western type diet is a known risk factor for colorectal cancer. Our group previously developed the total Western diet (TWD) for rodents with energy and nutrient profiles that emulate a typical Western diet. In this study, we tested the hypothesis that consumption of the TWD would enhance colitis, delay recovery from gut injury and promote colon tumorigenesis. In multiple experiments using the azoxymethane + dextran sodium sulfate or ApcMin/+ mouse models of colitis-associated colorectal carcinogenesis (CAC), we determined that mice fed TWD experienced more severe and more prolonged colitis compared to their counterparts fed the standard AIN93G diet, ultimately leading to markedly enhanced colon tumorigenesis. Additionally, this increased tumor response was attributed to the micronutrient fraction of the TWD, and restoration of calcium and vitamin D to standard amounts ameliorated the tumor-promoting effects of TWD. Finally, exposure to the TWD elicited large scale, dynamic changes in mRNA signatures of colon mucosa associated with interferon (IFN) response, inflammation, innate immunity, adaptive immunity, and antigen processing pathways, among others. Taken together, these observations indicate that consumption of the TWD markedly enhanced colitis, delayed recovery from gut injury, and enhanced colon tumorigenesis likely via extensive changes in expression of immune-related genes in the colon mucosa.
Effect of dicamba rate and application parameters on protoporphyrinogen oxidase inhibitor-resistant and -susceptible Palmer amaranth (Amaranthus palmeri) control

Throughout eastern Arkansas, Palmer amaranth resistant to protoporphyrinogen oxidase (PPO)-inhibiting herbicides (Group 14 herbicides) has become widespread. Most PPO-resistant Palmer amaranth biotypes possess a target-site mutation, but a metabolic resistance mechanism to fomesafen (Group 14) has also been identified. Once metabolic resistance manifests, plants may also be tolerant to other herbicides and sites of action. To evaluate whether varying spray parameters affected control of PPO-resistant Palmer amaranth in dicamba-tolerant crops, field trials were conducted in 2017 and 2018 at the Lon Mann Cotton Research Station near Marianna, AR, and on-farm in Marion, AR. The experiment included split plot factors of dicamba rate, nozzle type, and carrier volume, with a whole plot factor of population. Dicamba was applied at 560 or 1120 g ae ha−1 through 110015 TTI or AirMix nozzles at 70 or 140 L ha−1 to PPO-resistant or PPO-susceptible Palmer amaranth. Palmer amaranth control 14 d after treatment (DAT) was influenced by an interaction between population and carrier volume. PPO-resistant Palmer amaranth control 14 DAT was 81% regardless of carrier volume, compared with 90% and 95% control at 70 and 140 L ha−1, respectively, of the PPO-susceptible population. An interaction between nozzle type and carrier volume influenced Palmer amaranth control 21 DAT, whereas AirMix nozzles at 140 L ha−1 controlled Palmer amaranth at a greater level (94%) than any other nozzle and carrier volume combination (≤90%). An interaction between population and dicamba rate influenced the relative density of Palmer amaranth 21 DAT. PPO-resistant Palmer amaranth density was less affected by dicamba at either rate than PPO-susceptible Palmer amaranth, relative to the nontreated check. Results concur with those of other research that suggest PPO-resistant Palmer amaranth is harder to control with dicamba. Otherwise, increasing carrier volume affected overall Palmer amaranth control to a greater degree than any other factor.
Why Does Any of This Matter?: What Can We Learn from These Strategies?

This chapter examines going public and other presidential rhetorical tools to help highlight why it is important to explore how Donald Trump uses language to maximize his advantage. The chapter explores some of his more outrageous statements and how he intentionally does this to appeal to specific audiences. This chapter examines him from the perspective of Barber’s presidential typologies and also through the lens of populism to help explain why so many people find Trump’s message attractive. This chapter provides an overview and summarizes some of the more salient findings.
Racismo y desvalorización del trabajo de las mujeres indígenas en Guatemala: desde la economía doméstica hasta el Caso Sepur Zarco

The Guatemalan 2013 genocide trial, where ex-President Efrain Rios Montt was convicted, and the Sepur Zarco trial held in February of 2016 brought to focus the sexual violence suffered by Maya women at a massive scale during the over-three-decades long civil conflict. In this article, the instances of sexual violence and sexual slavery suffered by —at least—fifteen Q’eqchi’ women between 1982 and 1988 are addressed in parallel to a dimension of the Sepur Zarco trial which has been for the most part overlooked: the situation of domestic slavery that was also inflicted on the Maya women survivors. Specifically, I suggest that the process of devaluation of indigenous women’s reproductive work (intensified to the extreme during the Maya genocide) needs to be historically understood in relation to the capitalist modernization projects put into motion by Central American liberal elites during the last decades of the 19th century. The liberal modernization projects relied upon two opposing —and heavily racialized— concepts of work: the notion of “productive work” and the notion of “unproductive work.” These notions eventually found their way into the Central American households and actively contributed to the creation of a renovated hierarchical order structured around forms of domestic work considered to be “productive” (i.e., the domestic work performed by lettered and modernized housewives) and other forms of work considered “unproductive” (that is, the work performed by indigenous domestic servants). Ultimately, these imaginaries of inequality that thrived within the households of the isthmus have survived until today, when ample sectors of the population still equate “indigenous women” with “domestic servants,” and when different forms of devaluation, exploitation, and other forms of abuse are inflicted upon local domestic workers with total impunity.
Telemedicine During a Pandemic with Osteopathic Considerations

Health care continues to make strides in the industry by incorporating technological innovation to capture consumer demand and financial growth. Over the past 10 years, significant technology advances in health care include developing electronic health records, patient portals, self-service kiosks, remote monitoring devices, genome sequencing and telemedicine. The topics covered include visit how-to's, presenting yourself professionally, displaying empathy and treating the whole person in the virtual platform. Practice management topics include benefits of telemedicine, billing and coding, reimbursement, and legal consideration. Multiple tables display various topics, including different types of telemedicine, different virtual platforms, CPT codes to code the visit and billing modifiers associated with telemedicine.
Indicateurs d’hypermédicalisation de la prise en charge obstétricale à partir de l’évolution des grossesses, des accouchements et des naissances au Chili

Etude epidemiologique dont l’objectif est d’identifier des indicateurs de l’hypermedicalisation de la prise en charge obstetricale a partir des donnees disponibles dans la Base nationale des naissances vivantes au Chili pour la periode 1991–2017. Trois resultats montrent l’hypermedicalisation obstetricale a travers une diminution significative a l’echelle de la population : 1) les accouchements assistes par la sage-femme ; 2) la duree moyenne des grossesses ; 3) la moyenne des poids de naissance. L’impact des interventions medicales obstetricales systematiques devrait etre precise.
Fiducial Markers for Pose Estimation

Robust localization is critical for the navigation and control of mobile robots. Global Navigation Satellite Systems (GNSS), Visual-Inertial Odometry (VIO), and Simultaneous Localization and Mapping (SLAM) offer different methods for achieving this goal. In some cases however, these methods may not be available or provide high enough accuracy. In such cases, these methods may be augmented or replaced with fiducial marker pose estimation. Fiducial markers can increase the accuracy and robustness of a localization system by providing an easily recognizable feature with embedded fault detection. This paper presents an overview of fiducial markers developed in the recent years and an experimental comparison of the four markers (ARTag, AprilTag, ArUco, and STag) that represent the state-of-the-art and most widely used packages. These markers are evaluated on their accuracy, detection rate and computational cost in several scenarios that include simulated noise from shadows and motion blur. Different marker configurations, including single markers, planar and non-planar bundles and multi-sized marker bundles are also considered in this work.
