Sexual Narcissism and Infidelity in Early Marriage

There is theoretical reason to believe that narcissism is associated with infidelity. Yet, studies that have examined this association have yielded inconsistent results. Given that these inconsistencies may have emerged because prior studies used global assessments of narcissism that do not capture the extent to which the components of narcissism are activated in the sexual domain, the current research drew from two longitudinal studies of 123 married couples to examine the extent to which sexual narcissism predicted marital infidelity. Consistent with the idea that narcissism predicts sexual behavior when activated in the sexual domain, own sexual narcissism was positively associated with infidelity, controlling for own marital and sexual satisfaction, own globally-assessed narcissism, partner globally-assessed narcissism, and partner sexual narcissism. Helping to explain why this association emerged, further analyses demonstrated that it was driven by all four facets of sexual narcissism—sexual exploitation, grandiose sense of sexual skill, sexual entitlement (Study 1 only), and lack of sexual empathy (husbands only). Additionally, although partner sexual narcissism was unrelated to infidelity on average, partners’ grandiose sense of sexual skill and partners’ sexual entitlement (Study 2 only) were positively associated with infidelity, and partners’ lack of sexual empathy was negatively associated with infidelity (Study 2 only). These findings highlight the benefits of using domain-specific measures of sexual narcissism in research on sexual behavior and the benefits of using domain-specific measures of personality more generally.

We thank Sally Partridge for contributing her [very insightful analysis and thoughts][1] ([1][2]). In our study ([2][3]), we found that it was possible to track a pKpQIL plasmid using a MALDI-TOF MS peak corresponding to a cleavage product of p019, a pKpQIL-encoded protein. Dr. Partridge points out
Structure of a cannabinoid receptor and functional expression of the cloned cDNA

Marijuana and many of its constituent cannabinoids influence the central nervous system (CNS) in a complex and dose-dependent manner. Although CNS depression and analgesia are well documented effects of the cannabinoids, the mechanisms responsible for these and other cannabinoid-induced effects are not so far known. The hydrophobic nature of these substances has suggested that cannabinoids resemble anaesthetic agents in their action, that is, they nonspecifically disrupt cellular membranes. Recent evidence, however, has supported a mechanism involving a G protein-coupled receptor found in brain and neural cell lines, and which inhibits adenylate cyclase activity in a dose-dependent, stereoselective and pertussis toxin-sensitive manner. Also, the receptor is more responsive to psychoactive cannabinoids than to non-psychoactive cannabinoids. Here we report the cloning and expression of a complementary DNA that encodes a G protein-coupled receptor with all of these properties. Its messenger RNA is found in cell lines and regions of the brain that have cannabinoid receptors. These findings suggest that this protein is involved in cannabinoid-induced CNS effects (including alterations in mood and cognition) experienced by users of marijuana.
Percutaneous brachial catheterization using a modified sheath and new catheter system

An alternative method for left heart catheterization via the brachial artery, without cutdown, is described. Percutaneous brachial catheterization was done with a modified 7F side-arm sheath with check valve. A modified 7F high flow catheter was developed employing characteristics of both multipurpose and Sones catheters. The technique was used in 100 patients for left heart catheterization, in patients with and without aortic valve disease, for left ventricular angiography and selective coronary angiography. There were no failures or serious complications. All puncture sites were managed with 15-20 minutes of compression using only a blood pressure cuff or finger pressure. Bleeding was controlled with restoration of the radial pulse in all but one patient, who had severe peripheral brachial atherosclerosis. Cutdown and thrombectomy performed before he left the laboratory using standard catheterization techniques promptly restored blood flow. It is our impression that this technique facilitated outpatient catheterizations, repeat catheterizations at sites of previous cutdowns, and reduced patient discomfort.
Photon Beamlines and Diagnostics at LCLS

Abstract The LCLS hard X-ray Free Electron Laser at SLAC reported first lasing in April 2009. Since then two successful user runs have been completed at the two soft X-ray stations. The first hard X-ray station has started commissioning in July 2010. Beam diagnostics play an essential role for tuning the machine and delivering the requested beam properties to the users. An overview of the LCLS photon diagnostics will be presented including some selected commissioning results. Plans for future improvements and upgrades will be briefly discussed.
Ellipsometry with Imperfect Components Including Incoherent Effects

The problem of relating the specimen ψ and Δ to the instrument readings and component imperfections is solved by a general technique without any restriction on the nature of the imperfections. Thus, for the first time, small incoherent effects in the ellipsometer can be treated. The solution is explicit and is given in terms of the properties of the ideal ellipsometer and the Mueller imperfection matrices of the optical devices. After deriving the general solution, we consider a conventional ellipsometric arrangement. Arrays of coupling constants are introduced which clearly show the effect of imperfections on ψ and Δ. Also, we indicate in a schematic way the elements that remain effective after averaging over two and four zones. Component depolarization is discussed and the matrix elements contributing to it are found. Besides allowing all previous results to be obtained, some new conclusions of this analysis are: a small depolarization of the polarizer light output affects ψ (0.15° error in ψ for 1% depolarization) and this effect remains after two- and four-zone averaging. The effect of both coherent and incoherent p ↔ s cross scattering by the cell windows cancels if a two-zone average is taken. The same applies for the coherent and incoherent cross scattering by the specimen-surface roughness or by surface optical activity. For the compensator, cross scattering caused by birefringence and optical activity cancels only if a four-zone average is taken.
TU-C-BRE-07: Quantifying the Clinical Impact of VMAT Delivery Errors Relative to Prior Patients’ Plans and Adjusted for Anatomical Differences

Purpose: There is increased interest in the Radiation Oncology Physics community regarding sensitivity of pre-treatment IMRT/VMAT QA to delivery errors. Consequently, tools mapping pre-treatment QA to the patient DVH have been developed. However, the quantity of plan degradation that is acceptable remains uncertain. Using DVHs adapted from prior patients’ plans, we developed a technique to determine the magnitude of various delivery errors required to degrade a treatment plan to outside the clinically accepted range. Methods: DVHs for relevant organs at risk were adapted from a population of prior patients’ plans using a machine learning algorithm to establish the clinically acceptable DVH range specific to the patient’s anatomy. We applied this technique to six low-risk prostate cancer patients treated with single-arc VMAT and compared error-induced DVH changes to the adapted DVHs to determine the magnitude of error required to push the plan outside of the acceptable range. The procedure follows: (1) Errors (systematic ' random shift of MLCs, gantry-MLC desynchronization, dose rate fluctuations, etc.) were simulated and degraded DVHs calculated using the Varian Eclipse TPS. (2) Adapted DVHs and acceptable ranges for DVHs were established. (3) Relevant dosimetric indices and corresponding acceptable ranges were calculated from the DVHs. Key indices includedmore » NTCP (Lyman-Kutcher-Burman Model) and QUANTEC’s dose-volume Objectives: s of V75Gy≤0.15 for the rectum and V75Gy≤0.25 for the bladder. Results: Degradations to the clinical plan became “unacceptable” for 19±29mm and 1.9±2.0mm systematic outward shifts of a single leaf and leaf bank, respectively. All other simulated errors fell within the acceptable range. Conclusion: Utilizing machine learning and prior patients’ plans one can predict a clinically acceptable range of DVH degradation for a specific patient. Comparing error-induced DVH degradations to this range, it is shown that single-arc VMAT plans for low-risk prostate are relatively insensitive to many potential delivery errors.« less
Predictors of carotid stenosis in older adults with and without isolated systolic hypertension.

This study was designed to determine the prevalence of carotid stenosis and atherosclerosis in older adults with and without isolated systolic hypertension and to determine risk factors for carotid artery disease in these two groups.Duplex scans were performed on 187 participants of the Systolic Hypertension in the Elderly Program and on 187 normotensive control subjects. Doppler measures of blood flow velocity were used to determine the prevalence of internal carotid artery stenosis.Carotid stenosis was found in 25% of hypertensive participants but in only 7% of normotensive participants (p or = 160 mm Hg was the strongest predictor of carotid stenosis. Other variables independently related to stenosis were diastolic blood pressure of or = 80 beats per minute (p = ...
Can we spot a neighborhood from the air? Defining neighborhood structure in Accra, Ghana

Slums are home to a large fraction of urban residents in cities of developing nations, but little attempt has been made to go beyond a simple slum/non-slum dichotomy, nor to identify slums more quantitatively than through local reputation. We use census data from Accra, Ghana, to create an index that applies the UN-Habitat criteria for a place to be a slum. We use this index to identify neighborhoods on a continuum of slum characteristics and on that basis are able to locate the worst slums in Accra. These do include the areas with a local reputation for being slums, lending qualitative validation to the index. We show that slums also have footprints that can be identified from data classified from satellite imagery. However, variability among slums in Accra is also associated with some variability in the land cover characteristics of slums.
Ofloxacin versus Vancomycin/Polymyxin for prevention of infections in granulocytopenic patients☆

Abstract Selective antimicrobial decontamination with norfloxacin was compared with vancomycin/polymyxin for prophylaxis of bacterial infections in granulocytopenic patients. In the group of patients receiving norfloxacin, there were a lower number of acquired gram-negative bacillary organisms per patient (0.88 versus 1.86, p=0.002), fewer patients with documented infection (16 of 36 versus 20 of 30, p=0.12), and fewer cases of gram-negative septicemia (0 of 36 versus five of 30, p=0.02). Norfioxacin was better tolerated (30 of 36 versus 16 of 30 patients highly compliant, p=0.02), and associated with fewer gastrointestinal side effects (eight of 36 versus 14 of 36 patients, p=0.07). These results suggest that norfloxacin is a more tolerable and efficacious oral antimicrobial agent than vancomycin/polymyxin for the prevention of serious gram-negative bacillary infections in granulocytopenic patients.
Multivalent Sequence Recognition by Epstein-Barr Virus Zta Requires Cysteine 171 and an Extension of the Canonical B-ZIP Domain

Epstein-Barr virus (EBV) immediate-early protein Zta is a member of the basic-leucine zipper (B-ZIP) family of DNA binding proteins that has an unusual capacity to recognize multiple DNA recognition sites, including AP-1 and C/EBP binding sites. To better understand the structure and function of Zta, we have mutagenized cysteine residues within or adjacent to the B-ZIP domain. We found that serine substitution for cysteine 171 (C171S), which lies outside and amino terminal to the B-ZIP basic region, completely abrogates Zta capacity to initiate lytic cycle replication. C171S disrupted Zta transcription activation function of several EBV lytic cycle promoters, including the BMRF1 gene (EA-D) and the other lytic activator, Rta. Overexpression of Rta could not rescue the C171S defect for transcription reactivation or viral DNA replication. Zta C171S was defective for binding to these promoters in vivo, as measured by chromatin immunoprecipitation assay. Purified Zta C171S bound AP-1 sites similar to wild-type Zta, but it was incapable of binding several degenerate Zta sites, including a consensus C/EBP site. Zta truncation mutations reveal that residues N terminal to the B-ZIP (amino acids 156 to 178) confer C/EBP binding capacity to the otherwise AP-1-restricted DNA recognition function. Comparison among viral orthologues of Zta suggest that a conserved N-terminal extension of the consensus B-ZIP domain is required for this multivalent DNA recognition capacity of Zta and is essential for viral reactivation.
Transcriptional analysis of the major surface array gene of Caulobacter crescentus.

Abstract The major component of the paracrystalline surface array of Caulobacter crescentus CB15 and one of the most abundant cellular proteins is a protein designated 130K. We have determined the DNA sequence of the 5' portion of the 130K gene, including the N-terminal one-third of the protein coding region, and analyzed the transcription of the gene. The site of transcription initiation was determined by S1 mapping of Caulobacter RNA. Although the DNA sequence upstream from the transcription start site showed significant homology to the consensus promoter sequences of Escherichia coli, S1 analysis of RNA from E. coli carrying the 130K gene on a plasmid indicated that the 130K promoter was not transcribed by E. coli RNA polymerase in vivo. Quantitative S1 analysis of RNA isolated from synchronously growing Caulobacter cells suggested that this promoter was not under developmental regulation; the amount of 130K transcript varied no more than 1.5-fold during the cell cycle. The length of the 130K mRNA was determined to be 3.3 kilobases by Northern (RNA blot) analysis, indicating that the 130K mRNA is not part of a polycistron. The amino acid sequence predicted from the DNA sequence agreed well with the N-terminal amino acid sequence determined by sequencing of the 130K protein. The 130K protein appears to be synthesized without an N-terminal leader sequence, but the N-terminal 20 amino acids are relatively hydrophobic and may function like a signal sequence during transmembrane translocation.
Behavior, cognition, and quality of life after adenotonsillectomy for pediatric sleep-disordered breathing: summary of the literature.

OBJECTIVE: To summarize published studies that evaluate whether adenotonsillectomy performed for sleep-disordered breathing in children is associated with improvements in behavior, cognitive function, and quality of life, whether those improvements show correlation with polysomnographic parameters, and suggest how future studies may provide additional clinically significant information. METHODS: A computerized search of the medical literature was performed for articles published between 1950 and March 2007 with the use of the OVID Medsearch database. RESULTS: Analysis revealed 25 articles that satisfied the inclusion and exclusion criteria. All studies showed improvement in one or more of the specified outcome measures including general or disease specific quality of life, behavioral problems including hyperactivity and increased aggression or neurocognitive skills, such as memory, attention, or school performance. Limited correlation was often seen between improvements in outcome measures and polysomnographic variables. CONCLUSION: Current studies strongly suggest adenotonsillectomy performed for sleep-disordered breathing in children is associated with improvements in quality of life, behavior, and cognitive function, but large, randomized, controlled studies are needed to provide definitive evidence of the benefits of this commonly performed surgical procedure in the general population. © 2008 American Academy of Otolaryngology‐Head and Neck Surgery Foundation.

Detail vs. simplifying assumptions for simulating semiconductor manufacturing lines

Simulating semiconductor manufacturing lines is necessary in order to understand how various factors interact to affect the performance of these complex lines. The author reports on the effects of the commonly made assumptions of no rework, representing rework by increasing process times, no operator constraints, and no machine failures. The author uses a detailed, flexible model in which the assumptions may or may not be made. The base case, validated for a real line, makes none of the simplifying assumptions listed and is compared with subsequent runs making each assumption in turn. Generally, performance is degraded. In some cases the performance measures (resources utilization, work-in-process, and cycle times) remain within 20% of the base case. >
Residual manifestations of hypercortisolemia following surgical treatment in a patient with Cushing syndrome

Cushing Syndrome is difficult to diagnose, and the comorbidities and persistent late effects of hypercortisolemia after treatment of the primary disease are challenging for the patient and the endocrinologist. To report the case of a girl with obesity and hypertension, ultimately diagnosed with Cushing syndrome due to primary pigmented nodular adrenocortical disease. In this case, the complications of hypercortisolism persisted short term despite surgical intervention. A 4 year old morbidly obese African-American girl with developmental delay presented with hypertensive emergency in the ER and 18-month history of progressive weight gain. Her previous history included premature adrenarche, hypertension, seizures and a random high cortisol with suppressed ACTH. She was subsequently stabilized, and a diagnostic work-up persistently demonstrated elevated cortisol and suppressed ACTH. An abdominal MRI showed bilateral adrenal multinodular disease, consistent with multinodular hyperplasia of the adrenal glands. Based on these findings the patient underwent a bilateral adrenalectomy, which confirmed primary pigmented nodular adrenocortical disease. The patient had a complicated, protracted post-operative course requiring adjustment of therapy for persistent hypertension. Two months after surgery, she was readmitted to the Emergency Department with hyperpyrexia and hypertension and succumbed to the complications of sepsis. This case highlights the significant diagnostic and therapeutic challenges in treating children with Cushing syndrome. Resolution of the source of hypercortisolemia does not imply regression of hypertension or recovery of the immune system. Although the child underwent bilateral adrenalectomy, persistent consequences of prolonged severe hypercortisolism contributed to her death two months later.
Crustal remanence in an internally magnetized non-uniform shell: a possible source for Mercury’s magnetic field?

We consider the magnetic field of a shell uniformly magnetized by an internal dipole that is subsequently removed. The Gauss coefficients of the resulting field are given in terms of the spherical harmonic coefficients of the shell thickness. This general solution can easily be reduced to common special cases by superposition. For a shell of constant thickness the external field vanishes (by Runcorn’s theorem). For shell thickness variations caused by a laterally varying temperature field, the resulting magnetic moments are appreciably greater than the previously published correction due to rotational flattening. If the crust of Mercury contains rocks capable of sustaining high specific magnetizations, orif Mercury had a now-extinct dynamo field which was more intense than the Earth’s present core field, then the Mariner 10 observations of Mercury’s magnetic field are consistent in magnitude and geometry with the predictions of this model. For such a scenario, the requirement of a fractionally large molten outer core supporting a dynamo at present would be relaxed. The origin of Mercury’s magnetic field will be addressed with measurements to be made by NASA’s MESSENGER spacecraft.
On the Management Science Ten Page Constraint

In December 1971, a ten page constraint was instituted for most papers published in Management Science. The implications of this page constraint policy are examined, and a modified policy is proposed which retains all of the advantages of the current policy while eliminating some of its disadvantages.
Synthesis of a novel triple-site diphosphinoamine (PNP) ligand and its applications in ethylene tetramerization

A novel triple-site diphosphinoamine (PNP) ligand was synthesized and characterized. In combination with Cr(III) and methylaluminoxane (MAO), it generated active catalytic systems for ethylene tetramerization toward 1-octene with high catalytic activity and long lifetime. The effects of reaction temperature, molar ratio of Al/Cr and molar ratio of ligand/Cr on catalytic activity and selectivity to 1-octene were studied with reaction kinetics of the catalytic system for ethylene tetramerization described. At the Al/Cr molar ratio of 100, the catalytic activity is up to 2.29x106 g·mol−1 (Cr)·h−1 and the selectivity to 1-octene is 49.65 wt%.
Effects of adaptive prompted self-explanation on robust learning of second language grammar

Prompted self-explanation is a successful intervention for many domains. However, in our previous work within the domain of second language grammar learning, we found no advantage for self-explanation over practice alone. Here, we continue testing the generality of self-explanation through the development of an adaptive self-explanation tutor and report on results of a classroom evaluation (N=92) in which we compare the adaptive tutor to a practice-only tutor. We investigate both procedural and declarative knowledge acquisition as well as long-term retention. Results show that while self-explanation takes more time than practice alone, it leads to greater learning of declarative knowledge. However, there are no differences between conditions on immediate or long-term retention measures of procedural knowledge.
Preparing the technical communicator of the future

It is observed that advances in information technology are drastically changing the profession of technical communication and the role of the technical communicator in developing and managing information. It is argued that educators must face the challenge posed by these advances to prepare students for the profession as it is now and as it will be in the future. It is suggested that one answer to this challenge is experiential learning theory, which places experience at the center of the learning process. >
Increased nitric oxide production by airway cells of sensitized and challenged IL-10 knockout mice

The anti-inflammatory cytokine inter- leukin (IL)-10 suppresses inducible nitric oxide synthase (iNOS); therefore, NO production should increase in the absence of IL-10. Production of NO (as nitrite) by bronchoalveolar lavage cells of IL-10 knockout ( 2/2 ) mice was assessed after ovalbumin sensitization and airway challenge (S/C) and was compared with the IL-10-sufficient, wild-type (WT) C57Bl6. Eosinophil recruitment occurred in S/C WT and IL-10 2/2 mice, suggesting allergic airway inflammation. Alveolar macrophages (per g mouse) were unchanged (;3310 4 cells) with the exception of a doubling in the S/C IL-10 2/2 mice (;6310 4 cells, P<0.05). NO production (per million cells) was doubled in cells from S/C IL-10 2/2 (15.3 mM) mice compared with WT (7.6 mM, P<0.05). Inhi- bition of iNOS by L-N 5 -(1-iminoethyl)-ornithine re- duced NO production in all S/C mice, confirming that the increase was a result of up-regulation of iNOS. We conclude that IL-10 is a critical cytokine regulating iNOS in murine airway cells and that its absence can lead to up-regulation of iNOS and development of allergic airway inflammation. J. Leukoc. Biol. 70: 730-736; 2001.
Tweets, Polls, and Quotes: Gatekeeping and Bias in On-Screen Visuals During the Final 2012 Presidential Debate

This study content analyzed the on-screen visuals (i.e., candidate quotes, live Twitter feed, and poll results) displayed during the final presidential debate on the ABC News/Yahoo News live-streaming online coverage. Gatekeeping and research on political campaign coverage were used to provide rationale about the nature of the on-screen visuals. Results largely confirmed previous research into presidential campaign coverage: The on-screen visuals revealed a reliance on elite sources (media-related professionals and public figures), the on-screen visuals were largely neutral in nature for the candidates (although there was a slight pro-Obama advantage in the tweets and a slight pro-Romney advantage in the quoted material shown on-screen), and the on-screen visuals focused on horserace, strategy, and image at the expense of issue and policy discussion.
Type A aortic dissection complicated with fistulization into the right atrium and right-to-left shunt

Fistulization between the aorta and the right atrium is a rare complication of ascending aortic dissection. Because of the typical haemodynamic unstability, the diagnosis is often made by bedside or intraoperative transoesophageal echocardiography. The treatment is surgical, but with very high mortality. We describe a case of type A aortic dissection complicated with shock and fistulization into the right atrium with the right-to-left shunt through a patent foramen ovale. Surgical repair was successful.
Rate-Quality Control Method of Identifying Hazardous Road Locations

A brief historical perspective on the development of the rate-quality control method and its use in the identification of hazardous roadway locations is presented. The evolution of the formulas used in the ratequality control method from their origin in the late 1950s to their present form is traced. The derivation of the basic formulas used in the method is also presented and discussed. It is suggested that, contrary to assertions in the literature, the accuracy of the equations used in the ratequality method is not improved by eliminating the normal approximation correction factor from the original equations. The need for the correction factor is particularly apparent at higher probability levels. Charts are provided for determining an appropriate correction factor for those who may wish to incorporate these factors into the equations.
Aplanatic grazing incidence diffraction grating: a new optical element.

We present the theory of a grazing incidence reflection grating capable of imaging at submicron resolution. The optic is mechanically ruled on a spherical or cylindrical surface with varied groove spacings, delivering diffraction-limited response and a wide field of view at a selected wavelength. Geometrical aberrations are calculated on the basis of Fermat’s principle, revealing significant improvements over a grazing incidence mirror. Aplanatic and quasi-aplanatic versions of the grating have applications in both imaging and scanning microscopes, microprobes, collimators, and telescopes. A 2-D crossed system of such gratings, similar to the grazing incidence mirror geometry of Kirkpatrick and Baez, could potentially provide spatial resolutions of ~200 A.
High level perinuclear antineutrophil cytoplasmic antibody (pANCA) in ulcerative colitis patients before colectomy predicts the development of chronic pouchitis after ileal pouch-anal anastomosis

BACKGROUND The reported cumulative risk of developing pouchitis in ulcerative colitis (UC) patients undergoing ileal pouch-anal anastomosis (IPAA) approaches 50% after 10 years. To date, no preoperative serological predictor of pouchitis has been found. AIMS To assess whether preoperative perinuclear antineutrophil cytoplasmic antibody (pANCA) expression was associated with acute and/or chronic pouchitis after IPAA. METHODS Patients were prospectively assessed for the development of clinically and endoscopically proved pouchitis. Serum obtained at the time of colectomy in 95 UC patients undergoing IPAA was analysed for pANCA by ELISA and indirect immunofluorescence. pANCA+ patients were stratified into high level (>100 ELISA units (EU)/ml) (n=9), moderate level (40–100 EU/ml) (n=32), and low level ( RESULTS Sixty of the 95 patients (63%) expressed pANCA. After a median follow up of 32 months (range 1–89), 32 patients (34%) developed either acute (n=14) or chronic (n=18) pouchitis. Pouchitis was seen in 42% of pANCA+ patients compared with 20% of pANCA− patients (p=0.09). There was no significant difference in the incidence of acute pouchitis between the three pANCA+ patient subgroups. The cumulative risk of developing chronic pouchitis among patients with high level pANCA (56%) before colectomy was significantly higher than in patients with medium level (22%), low level (16%), and those who were pANCA− (20%) (p = 0.005). Multivariate analysis revealed that the sole parameter significantly associated with the development of chronic pouchitis after IPAA was the presence of high level pANCA before colectomy (p=0.005). CONCLUSION High level pANCA before colectomy is significantly associated with the development of chronic pouchitis after IPAA.
Quantitative Data on Four Species of Eimeria in Eastern Chipmunks and Red Squirrels

SYNOPSIS. Total counts of Eimeria vilasi and E. wisconsinensis oocysts in 0.05 g fecal samples from the eastern chipmunk over a 2-year period indicated that the 2 species had respective occurrences of 100% and 11% and an actual abundance ratio of 35 to 1. In the red squirrel similar counts of E. tamiasciuri and E. toddi over a 3-year period indicated occurrences of 98% and 6% and an actual abundance ratio of 26 to 1, respectively. These results parallel a similar dichotomy in percent occurrence of 7 Eimeria in the sciurid genera Cynomys and Marmota.
Market Timing and Roulette Wheels

Nobel laureate William F. Sharpe and others have alerted investors to the potential pitfalls of market timing. We also conclude from the study reported here that market timing is generally a difficult game. But the difficulty varies substantially over time-which has some intriguing implications for performance evaluation. Using a new measure of investment performance that we call the “roulette wheel” measure, we analyzed monthly, quarterly, and annual market-timing strategies in the 1926–99 period for six major U.S. asset classes. In the 1995–99 period, buying and holding large-capitalization stocks would have outperformed about 99.8 percent of the more than 1 million possible quarterly switching sequences between large-cap stocks and U.S. T-bills. In 1994, however, if 1,000 portfolio managers had made monthly random choices between large-cap stocks and T-bills, about 591 of them would probably have beaten a buy-and-hold strategy. If 650 of the 1,000 had beaten a buy-and-hold strategy, should all 650 have...
Optimal Long Code Test with One Free Bit

For arbitrarily small constants epsilon, delta ≫ 0$, we present a long code test with one free bit, completeness 1-epsilon and soundness delta. Using the test, we prove the following two inapproximability results:1. Assuming the Unique Games Conjecture of Khot, given an n-vertex graph that has two disjoint independent sets of size (1/2-epsilon)n each, it is NP-hard to find an independent set of size delta n.2. Assuming a (new) stronger version of the Unique Games Conjecture, the scheduling problem of minimizing weighted completion time with precedence constraints is inapproximable within factor 2-epsilon.
Tectonic Processes on Europa: Tidal Stresses, Mechanical Response, and Visible Features

Abstract Europa's orbital eccentricity, driven by the resonance with Io and Ganymede, results in “diurnal” tides (3.5-day period) and possibly in nonsynchronous rotation. Both diurnal variation and nonsynchronous rotation can create significant stress fields on Europa's surface, and both effects may produce cracking. Patterns and time sequences of apparent tectonic features on Europa include lineaments that correlate with both sources of stress, if we take into account nonsynchronous rotation, after initial crack formation, by amounts ranging up to several tens of degrees. For example, the crosscutting time sequence of features in the Cadmus and Minos Linea region is consistent with a combined diurnal and nonsynchronous tensile-stress field, as it evolves during tens of degrees of nonsynchronous rotation. Constraints on the rotation rate from comparing Voyager and Galileo images show that significant rotation requires >104yr, but could be fast enough to have allowed significant rotation since the last global resurfacing, even if such resurfacing was as recent as a few million years ago. Once cracking is initiated, diurnal tides work cracks so that they open and close daily. Although the daily effect is small, over 105yr double ridges could plausibly be built along the cracks with sizes and morphologies consistent with observed structures, according to a model in which underlying liquid water fills the open cracks, partially freezes, and is extruded during the daily closing of the cracks. Thus, several lines of observational and theoretical evidence can be integrated if we assume nonsynchronous rotation and the existence of a liquid water layer.
Common variants near CAV1 and CAV2 are associated with primary open-angle glaucoma in Caucasians from the USA

Primary open-angle glaucoma (POAG) is a genetically complex common disease characterized by progressive optic nerve degeneration that results in irreversible blindness. Recently, a genome-wide association study (GWAS) for POAG in an Icelandic population identified significant associations with single nucleotide polymorphisms (SNPs) between the CAV1 and CAV2 genes on chromosome 7q31. In this study, we confirm that the identified SNPs are associated with POAG in our Caucasian US population and that specific haplotypes located in the CAV1/CAV2 intergenic region are associated with the disease. We also present data suggesting that associations with several CAV1/CAV2 SNPs are significant mostly in women.
Fairy Tales and ESL Texts: An Analysis of Linguistic Features Using the Gramulator

Using the Gramulator, we analyzed the linguistic features of ESL texts and fairy tales. Our goal was to determine if fairy tales had the potential to be used as reading material for English language learners. The results of our analyses suggest that there are significant similarities between fairy tales and ESL texts, but that differences lie in the content of the text types with fairy tales appearing significantly more narrative in style and ESL texts appearing more expository.
"Some Things We Have Learned...": Managing Advertising Archives for Business and Non-Business Users

This essay reviews the experiences of Duke University's Special Collections Library in building major collections of advertising agency and trade organization archives. Duke has acquired extensive records of several still-existing agencies and organizations and has agreed contractually to service the collections for the records creators' business needs as well as to make large parts of the collections available for academic and general users. The author describes the agreements made with donors, the experiences of an out-of-house repository trying to build the collections, the management of a fee-based information service for business users, and outreach to the scholarly community. The efforts at Duke have been extremely successful, but not without pitfalls and opportunities to "learn the hard way".
La metonimia en una crónica de Carlos Monsivais. Hacia un periodismo democrático

The Concentric Maclaurin Spheroid method with tides and a rotational enhancement of Saturn's tidal response

Abstract We extend to three dimensions the Concentric Maclaurin Spheroid method for obtaining the self-consistent shape and gravitational field of a rotating liquid planet, to include a tidal potential from a satellite. We exhibit, for the first time, an important effect of the planetary rotation rate on tidal response of gas giants, whose shape is dominated by the centrifugal potential from rapid rotation. Simulations of planets with fast rotation rates like those of Jupiter and Saturn, exhibit significant changes in calculated tidal love numbers knm when compared with non-rotating bodies. A test model of Saturn fitted to observed zonal gravitational multipole harmonics yields k 2 = 0.413 , consistent with a recent observational determination from Cassini astrometry data (Lainey et al., 2016.). The calculated love number is robust under reasonable assumptions of interior rotation rate, satellite parameters, and details of Saturn’s interior structure. The method is benchmarked against several published test cases.
Throughput computing

A qualitative change in the scaling of semiconductor technology has ended the performance scaling of the single-thread processors that have been used as the building blocks for high-performance computers for the last decade and has made computers of all scales power limited. In today's power-limited regime, efficient high-performance computers must be built from throughput processors, processors, like GPUs, that are optimized for sustained performance per unit power --- rather than for single-thread performance. This talk will discuss some of the challenges and opportunities in the architecture and programming of future throughput processors. In these processors, performance derives from parallelism and efficiency derives from locality. Parallelism can take advantage of the plentiful and inexpensive arithmetic units in a throughput processor. Without locality, however, bandwidth quickly becomes a bottleneck. Communication bandwidth, not arithmetic is the critical resource in a modern computing system that dominates cost, performance, and power. This talk will discuss exploitation of parallelism and locality with examples drawn from the Imagine and Merrimac projects, from NVIDIA GPUs, and from three generations of stream programming systems.
Room Temperature Deposition of High Dielectric Constant, High Density Ceramic Thin Films

Future high-performance integrated circuits and electronic packaging technology require the integration of many passive components, including high storage capacitors, on the systems. Because of the low melting temperature metal lines and polymer dielectrics in these electronic systems, one cannot employ most of the existing high temperature deposition techniques to grow thin film components. In this paper, we will report our recent work on the room temperature deposition of amorphous ceramic thin films, including BaxTi 2−xOy and SiOx, using the newly developed partially ionized beam technique. This technique utilizes a small percent (<3%) of selfions derived from the depositing materials to bombard the surface growth front during deposition. It is shown that a dramatic control of the density (and therefore the leakage current) and uniformity of the film can be achieved using this deposition technique without post annealing. Al or Cu was used as the electrodes in our multilayer MIM (metal-insulator-metal) test structure. As deposited thin film capacitors with a capacitance ranging from 25 to 100 nF/cm 2 have been fabricated with tan δ <0.01, leakage current of <l.μA/cm2 at 0.5 MV/cm, and breakdown field strength of several MV/cm. These ceramic capacitors do not show any dispersion up to 1 GHz.
Victimization and perpetration of sexual violence in college-aged men and women.

Objective Sexual violence is a significant public health issue on college campuses. Much of the research to date has focused on sexual violence victimization with less data on perpetration of sexual violence. This analysis describes sexual violence victimization and perpetration experiences in a sample of college students. Methods We sought to recruit college students attending three universities in the United States. A cross-sectional survey design was used to contact students through e-mail or voluntary gatherings. Each participant completed a questionnaire focused on experiences of sexual violence. Results A total of 1,978 students consented to participate in the study with 1,829 completing the questions related to victimization experiences and 1,479 completing the questions related to perpetration experiences. Thirty-eight percent (n = 700) of the sample (men and women) reported sexual violence victimization. Victimization among women and men was 42.6% and 28.7%, respectively. Almost 6% (n = 100) of the sample reported sexual violence perpetration. Men reported a higher rate of perpetration, 14.5% (n = 60), compared to women, 3.8% (n = 40). Conclusion This study provides data on both victimization and perpetration experiences of college students. Both college men and women reported experiences of being victimized as well as perpetrating sexual violence. Understanding victimization and perpetration on college campuses will increase awareness, thus piercing the silence, of unwanted sexual experiences and help move college campuses toward a response.
Paraphrase and the Symmetry Objection

ABSTRACTThere is a puzzle about the use of paraphrase in philosophy, presented most famously in Alston's [1958] ‘Ontological Commitments’, but found throughout the literature. The puzzle arises from the fact that a symmetry required for a paraphrase to be successful seems to necessitate a symmetry sufficient for a paraphrase to fail, since any two expressions that stand in the means the same as relation must also stand in the has the same (unwanted) commitments as relation. I show that, while this problem does undermine some conceptions of paraphrase, on a proper understanding of paraphrase the puzzle gets no purchase. Since paraphrase is an important component of Quinean approaches to meta-ontology, this paper constitutes a partial defence of Quinean meta-ontology. Since paraphrase is an important component of traditional methods of philosophical inquiry, this paper constitutes a partial defence of traditional modes of philosophizing as well.

Effect of IGF-I's on Breast Cancer Cells Protein Expression in the Presence or Absence of ERα

ERα knockdown cell lines are generated from ERα-positive MCF-7 cells through stable transfection of an shRNA vector against ERα.Several knockdown clones expressed less than 50% ERα as compared with that of scramble vector control are obtained.One knockdown clone and a scramble vector control are then treated with IGF-Ⅰ followed by 2-Dimensional Electrophoresis(2-DE),and 27 differentially appeared spots are picked up and performed in-gel trypsinization,and resolved onto Mass Spectrum(MS),eventually 11 of these 27 spots are successfully identified by MS.This is the first study addressing the effect of ERα on IGF-Ⅰ/IGFR nodule using proteomics approaches and it provides some clues to understand the crosstalking between estrogen and IGF-Ⅰ,the two most important mitogens for breast cancer.
Study on Blind Recognition of Binary Linear Block Code

As an important component of channel coding,(n,k) linear block code is widely applied in deep-space communication,satellite communication,wireless communication and other digital communication fields. Meanwhile, the blind recognition of (n,k) linear block code becomes increasingly prominent. Based on analysis of the characteristics and principles of (n,k) linear block code the math models of blind recognition are established,the length of block code, generator matrix,and parity-check matrix estimated,the recent achievements in this field summarized,and the advantages and limitations of various blind recognition algorithms concluded. Finally the future research on this blind recognition of binary linear block code is suggested in this paper.
Clipless cholecystectomy: broadening the role of the harmonic scalpel.

BACKGROUND The ultrasonically activated (Harmonic) scalpel has proven to be an effective, efficient, and safe instrument for dissection and hemostasis in both open and laparoscopic surgical procedures. To date, the primary use of the Harmonic scalpel in laparoscopic cholecystectomies has been for the division of the cystic artery and liver bed dissection. Advancements in the Harmonic scalpel blade tip now provide for the reliable ultrasonic division and closure of the cystic duct. METHODS In a personal, prospective series involving 100 consecutive patients undergoing laparoscopic cholecystectomies, the Harmonic scalpel was used as the sole instrument for division of the cystic duct and artery as well as dissection of the liver bed. Two patients with large cystic ducts (over 5 mm) received an additional ductal ligature. RESULTS No patients developed postoperative hemorrhage or bile leakage. CONCLUSION The Harmonic scalpel provides complete hemobiliary stasis for most patients and is a safe alternative to standard clip or ligature closure of the cystic duct. Furthermore, there may be a cost savings inherent in a procedure utilizing a single disposable instrument.
To Debate or Not to Debate: The Question of Torture

In Chapter 2 “Of Thought and Discussion” of John Stuart Mill’ s On Liberty, he considers various objections to his argument for freedom of speech, including the following: “There are, it is alleged, certain beliefs so useful, not to say indispensable, to well-being that it is as much the duty of the government to uphold those beliefs as to protect any other of the interests of society.”2 The objection goes on to argue that the state might limit speech to protect these ideas for the well-being of society. Mill argues against this objection, but the question still echoes through to our own time: Are there ideas that are simply too important, too dangerous to allow public debate on?
’saying that now you are not as you were’: Hardy’s ‘Poems of 1912–13’

Thomas Hardy understood the source of his art to be a relationship between emotion and time: I have a faculty… for burying an emotion in my heart or brain for forty years, and exhuming it at the end of that time as fresh as when interred’ (Hardy 1984, 408). Emma Gifford Hardy’sunexpected death on 27 November 1912 prompted her mourning husband to exhume vividly emotional memories of the distant personal past. In reading Emma’sdiaries, which he burned, and her memoir Some Recollections, a manuscript reminiscence of her early life and their courtship in Cornwall, found after her death, Hardy was transported back to an earlier time when their love was new. At the same time, he was shocked at her descriptions of him as a husband in their often painful thirty-eight-year marriage. Emma’s ‘going’ enabled Hardy to see, as if for the first time, the emotional death between them that had preceded her physical death by many years.1 During the aftermath of her death, he wrote many verses about Emma, including the sequence, ‘Poems of 1912–13: Veteris vestigia flammae’, published in Satires of Circumstance, Lyrics, and Reveries (1914; Hardy 1982–95).
