Sharp constants for Moser‐Trudinger inequalities on spheres in complex space ℂn

The main results of this paper concern sharp constants for the Moser‐Trudinger inequalities on spheres in complex space ℂn. We derive Moser‐Trudinger inequalities for smooth functions and holomorphic functions with different sharp constants (see Theorem 1.1). The sharp Moser‐Trudinger inequalities under consideration involve the complex tangential gradients for the functions and thus we have shown here such inequalities in the CR setting. Though there is a close connection in spirit between inequalities proven here on complex spheres and those on the Heisenberg group for functions with compact support in any finite domain proven earlier by the same authors [17], derivation of the sharp constants for Moser‐Trudinger inequalities on complex spheres are more complicated and difficult to obtain than on the Heisenberg group. Variants of Moser‐Onofri‐type inequalities are also given on complex spheres as applications of our sharp inequalities (see Theorems 1.2 and 1.3). One of the key ingredients in deriving the main theorems is a sharp representation formula for functions on the complex spheres in terms of complex tangential gradients (see Theorem 1.4). © 2004 Wiley Periodicals, Inc.
Differential Growth Response of Various Crop Species to Arbuscular Mycorrhizal Inoculation

Abstract To investigate the growth response of various crop species to mycorrhizal inoculation, arbuscular mycorrhizal fungi were applied to Glycine max, Vigna angularis, Senna torn, Hordeum migare var. hexastichon. Zea mays, Sorghum bicolor, Allium tuberosum, Solanum melongena, and Capsicum annuum. The biomass of the inoculated crops was measured every two weeks for the 12-week growth period. By measuring biomass, we calculated the mycorrhizal responsiveness of the nine crop species. Among the nine crop species, four species showed a significant response to mycorrhizal inoculation. The shoot biomasses of V. angularis, C. annuum, A. tuberosum, and S. tora significantly increased with mycorrhizal inoculation.
Why are CEOS Rarely Fired? Evidence from Structural Estimation

I evaluate the forced CEO turnover rate and quantify effects on shareholder value by estimating a dynamic model. The model features learning about CEO ability and costly turnover. To fit the observed forced turnover rate, the model needs the average board of directors to behave as if replacing the CEO costs shareholders at least $200 million. This cost mainly reflects CEO entrenchment rather than a real cost to shareholders. The model predicts that shareholder value would rise 3% if we eliminated this perceived turnover cost, all else equal. The model also helps explain the relation between CEO firings, tenure, and profitability. Copyright (c) 2010 the American Finance Association.
Natural therapies assessment for the treatment of endometriosis.

STUDY QUESTION Can resveratrol and epigallocatechin-3-gallate (EGCG) inhibit the growth and survival of endometriotic-like lesions in vivo in a BALB/c model of endometriosis, and in vitro in primary cultures of human endometrial epithelial cells (EECs)? SUMMARY ANSWER Resveratrol and EGCG exerted a potent inhibitory effect on the development of endometriosis in a BALB/c murine model and on the survival of EECs. WHAT IS KNOWN ALREADY Endometriosis is a common condition associated with infertility and pelvic pain in women of reproductive age. Resveratrol and EGCG are two polyphenols with anticarcinogenic and antioxidant properties that have been proposed as natural therapies to treat endometriosis. STUDY DESIGN, SIZE, DURATION Fifty-six 2-month-old female BALB/c mice underwent surgical induction of endometriosis. Treatments with resveratrol or EGCG started 15 days post-surgery and continued for 4 weeks. Human biopsies were taken with a metal Novak curette from the posterior uterine wall from 16 patients with untreated endometriosis and 15 controls who underwent diagnostic laparoscopy for infertility. MATERIALS, SETTING, METHODS After the treatments, animals were sacrificed and lesions were counted, measured, excised and fixed. Immunohistochemistry for proliferating cell nuclear antigen and CD34 was performed for cell proliferation and vascularization assessment in the lesions. The terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) technique was performed for apoptosis evaluation. Peritoneal fluid was collected to analyze vascular endothelial growth factor levels. Human EECs were purified from proliferative-phase endometrial biopsies and cultured. The effect of both polyphenols on cell proliferation was determined by a colorimetric assay using the CellTiter 96®AQueous One Solution Cell Proliferation Assay kit and on apoptosis by the TUNEL technique, using an In Situ Cell Death Detection Kit with Fluorescein. MAIN RESULTS In the mouse model, both treatments significantly reduced the mean number (P < 0.05 versus control) and the volume of established lesions (P < 0.05 versus control). Treatments consistently statistically significantly diminished cell proliferation (resveratrol P < 0.01 and EGCG P < 0.05, versus control), reduced vascular density (resveratrol P < 0.01 and EGCG P < 0.001, versus control) and increased apoptosis within the lesions (resveratrol P < 0.01 and EGCG P < 0.05, versus control). Both compounds induced reduction in human EEC proliferation (P < 0.05 versus basal) and increased apoptosis (P < 0.05 versus basal) in primary cultures. LIMITATIONS In vitro studies were only carried out in epithelial cells from human eutopic endometrium. WIDER IMPLICATIONS OF THE FINDINGS The present findings are promising and will assist the development of novel natural treatments for endometriosis.

Subordinate Activation Tactics: Semi-professionals and Micro-level Institutional Change in Professional Organizations

This two-year ethnographic study of the primary care departments in two U.S. hospitals examines how managers can bring about micro-level institutional change in professional practice even when such change challenges professionals’ specialized expertise, autonomy, individual responsibility, and engagement in complex work, which previous research has shown to create difficulties. In this study, managers in both hospitals attempted to implement the same patient-centered medical home (PCMH) reforms among doctors, had the same external pressures for micro-level institutional change, worked under the same organizational and reimbursement structure, and had the same contextual facilitators of micro-level institutional change present within their organizations. But managers in one hospital successfully accomplished change in professional practice while those in the other did not. I demonstrate that managers can accomplish micro-level institutional change in professional organizations using “subordinate activation tactics”—first empowering and motivating subordinate semi-professionals to activate their favorable structural position vis-à-vis the targeted professionals on behalf of managers and next giving semi-professionals positional tools to use in their daily work to minimize the targeted professionals’ concerns about the threats associated with change.
Number 3 Fall 1996 49 NEW PRODUCT INTRODUCTIONS , SHAREHOLDERS ’ WEALTH , AND FIRST-MOVER ADVANTAGES

This paper examines the impact of announcements of new product introductions on the stock price of pioneering firms and their rivals to determine whether first-movers gain long-term competitive advantages. An analysis of 108 radically new products indicates that pioneering firms earn statistically significant positive abnormal returns at announcement while their rivals suffer statistically significant negative abnormal returns. These wealth effects indicate that pioneering firms attain sustainable first-mover advantages, in general. The crosssectional regression analysis of the abnormal returns reveals that the magnitude and/or durability of first-mover advantages are greater in fragmented but high-technology industries.
Automatic sortal Interpretation of German Nominalisations with-ung Towards using underspecified Representations in Corpora

In this paper we present work on using dependency structures in a process of automatic sortal interpretation of German nominalisations wit h -ung, such asMessung (‘measurement’) orZählung(‘count’). Many such-ung nominalisations are ambiguous with respect to their sortal interpretation ( cf. Ehrich and Rapp (2000) who lean heavily on McCawley (1968) and Lakoff (1972) for the notion f sortal ambiguity). In section 2.1 a more detailed discussion on sortal amb iguity as regards German -ungnominalisations is given. We are working towards a system for data extraction from corp us text that is able to carry out sortal disambiguation. Given the productivity of the-ung-formation process in German ( cf. Esau 1971 and Scheffler 2005) and the high frequency of -ung nominalisations in text ( cf. Knobloch 2002 or Osswald 2005), this ability is relevant, am ong others, for question answering or high quality information extraction3. In the first part of this paper (section 2), we discuss data for -ung nominalisations and the methodological bases of our work on their sortal inte rpretation. We present a preliminary case study on phenomena in the context of the -ung nominalisationsMessung, Zählung, andSchätzung(‘estimate’), and the potential of these contextual phenomena to constrain the sortal interpretation of -ungnominalisations (see section 2.2). From a descriptive point of view, such phenomona serve as “in dicators” of sortal readings. For the automatic sortal interpretation process, kno wledge about reading indicators is explicitly formulated as constraints which are appl ied to a given nominalisation. We model the sortal interpretation as a process of increment al specification where the context of a given nominalisation is used for its sortal inte rpr tation (section 2.3). The system we are conceiving will process tagged and parsed c orpus data, thus we do not have any discourse representations available whic h go beyond the sentence level. This means that the largest context available in the i nterpretation process is the sentence context. The order in which different constraints are applied is crucial to the sortal interpretation of a nominalisation at the sentence l ev l. We demonstrate (also in
Hα Spectroscopy of Galaxies at z > 2: Kinematics and Star Formation

We present near-infrared spectroscopy of Hα emission lines in a sample of 16 star-forming galaxies at redshifts 2.0 < z < 2.6. Our targets are drawn from a large sample of galaxies photometrically selected and spectroscopically confirmed to lie in this redshift range. We have obtained this large sample with an extension of the broadband UnGℛ color criteria used to identify Lyman break galaxies at z ~ 3. The primary selection criterion for IR spectroscopic observation was proximity to a QSO sight line; we therefore expect the galaxies presented here to be representative of the sample as a whole. Six of the galaxies exhibit spatially extended, tilted Hα emission lines; rotation curves for these objects reach mean velocities of ~150 km s-1 at radii of ~6 kpc, without corrections for inclination or any other observational effect. The velocities and radii give a mean dynamical mass of ≥ 4 × 1010 M☉. We have obtained archival Hubble Space Telescope images for two of these galaxies; they are morphologically irregular. One-dimensional velocity dispersions for the 16 galaxies range from ~50 to ~260 km s-1, and in cases in which we have both virial masses implied by the velocity dispersions and dynamical masses derived from the spatially extended emission lines, they are in rough agreement. We compare our kinematic results with similar measurements made at z ~ 3 and find that both the observed rotational velocities and velocity dispersions tend to be larger at z ~ 2 than at z ~ 3. We also calculate star formation rates (SFRs) from the Hα luminosities and compare them with SFRs calculated from the UV continuum luminosity. We find a mean SFRHα of 16 M☉ yr-1 and an average SFRHα/SFRUV ratio of 2.4, without correcting for extinction. We see moderate evidence for an inverse correlation between the UV continuum luminosity and the ratio SFRHα/SFRUV, such as might be observed if the UV-faint galaxies suffered greater extinction. We discuss the effects of dust and star formation history on the SFRs and conclude that extinction is the most likely explanation for the discrepancy between the two SFRs.
Determinants of Public Attitudes towards Euthanasia in Adults and Physician-Assisted Death in Neonates in Austria: A National Survey

Background Euthanasia remains a controversial topic in both public discourses and legislation. Although some determinants of acceptance of euthanasia and physician-assisted death have been identified in previous studies, there is still a shortage of information whether different forms of euthanasia are supported by the same or different sub-populations and whether authoritarian personality dispositions are linked to attitudes towards euthanasia. Methods A large, representative face-to-face survey was conducted in Austria in 2014 (n = 1,971). Respondents faced three scenarios of euthanasia and one of physician assisted death differing regarding the level of specificity, voluntariness and subject, requiring either approval or rejection: (1) abstract description of euthanasia, (2) abstract description of physician-assisted suicide, (3) the case of euthanasia of a terminally-ill 79-year old cancer patient, and (4) the case of non-voluntary, physician assisted death of a severely disabled or ill neonate. A number of potential determinants for rejection ordered in three categories (socio-demographic, personal experience, orientations) including authoritarianism were tested via multiple logistic regression analyses. Results Rejection was highest in the case of the neonate (69%) and lowest for the case of the older cancer patient (35%). A consistent negative impact of religiosity on the acceptance across all scenarios and differential effects for socio-economic status, area of residence, religious confession, liberalism, and authoritarianism were found. Individuals with a stronger authoritarian personality disposition were more likely to reject physician-assisted suicide for adults but at the same time also more likely to approve of physician-assisted death of a disabled neonate. Conclusion Euthanasia in adults was supported by a partially different sub-population than assisted death of disabled neonates.
Design of a Low-Voltage and Low-Distortion Mixer Through Volterra-Series Analysis

The factors that impact the intermodulation distortion performance of an active downconverting mixer are investigated. Through a Volterra-series analysis of the RF transconductor stage of the mixer, design principles are formulated to maximize the mixer's IIP3. To verify the theoretical analysis, a 0.3-1.2-GHz low-voltage mixer operating from a 0.9-V supply was designed, fabricated, and tested. The mixer employs a common-gate common-source RF transconductor stage with simultaneous distortion and noise cancellation. Experimental results reveal that the mixer can yield an IIP3 of - 0.8 dBm, a double-sideband noise figure below 4.8 dB, and a maximum conversion gain of 8.8 dB.
The Contexts of Electoral Accountability: Electoral Integrity Performance Voting in 23 Democracies

Abstract Electoral accountability is typically identified with retrospective economic voting even though it is widely recognized that explaining electors’ assignment of responsibility also implies considering issues other than the economy. Recently, scholars have also stressed the role of election quality in contributing to democratic legitimacy of elected authorities. In this perspective, electoral integrity as a valence issue would influence voters’ behaviour, structuring attitudes about accountability in substantial ways. This effect would also be moderated by individual- and country-level factors. I test these assumptions in 23 countries worldwide using a multilevel analysis of data from the sixth wave of the World Values Survey. Results indicate that the strength of the link between perceptions of electoral integrity and vote for the incumbent seems to be affected by individual characteristics such as partisanship, while it is also moderated by specific contextual characteristics such as government clarity of responsibility and pluralism of the media.
Prevalence, pattern, etiology, and management of maxillofacial trauma in a developing country: a retrospective study

Objectives This retrospective study aims to evaluate the prevalence of maxillofacial trauma in a developing country, along with its pattern, etiology and management. Data for the present study were collected from the Department of Dentistry, ESIC Medical College and Post Graduate Institute of Medical Sciences and Research, Chennai in India. Materials and Methods The medical records of patients treated for maxillofacial injuries between May 2014 and November 2015 were retrospectively retrieved and analyzed for prevalence, pattern, etiology, and management of maxillofacial trauma. SPSS software version 16.0 was used for the data analysis. Results Maxillofacial fractures accounts for 93.3% of total injuries. The mean and standard deviation for the age of the patients were 35.0±11.8 years and with a minimum age of 5 years and maximum age of 75 years. Adults from 20 to 40 years age groups were more commonly involved, with a male to female ratio of 3:1. There was a statistically significantly higher proportion of males more commonly involved in accident and injuries (P <0.001). Conclusion The most common etiology of maxillofacial injury was road traffic accidents (RTA) followed by falls and assaults, the sports injuries seem to be very less. In RTA, motorized two-wheelers (MTW) were the most common cause of incidents. The majority of victims of RTA were young adult males between the ages of 20 to 40 years. The malar bone and maxilla were the most common sites of fracture, followed by the mandible. The right side of the zygomatic complex was the predominant side of MTW injury. The majority of the zygomatic complex fractures were treated by conservative management. Open reduction and internal fixation were performed for indicated fracture patients.
Can a Work Organization Have an Attitude Problem? the Impact of Workplaces on Employee Attitudes and Economic Outcomes

In this study we examine whether a workplace can induce good or bad attitudes among its employees and whether any such ? workplace attitudes? affect economic outcomes. This study analyzes responses of thousands of employees working in nearly two hundred branches to the emp loyee opinion survey of a major US bank in 1994 and 1996. The results document the existence and persistence of a genuine workplace effect in how workers view their jobs and organizations. Employee attitudes differ significantly across branches in ways that cannot be explained by branches randomly drawing workers from a distribution of workers with different innate attitudes. Furthermore, newly hired workers adopt the favourable or unfavourable attitudes that the branches exhibited before they arrived. These workplace attitudes also have significant effects on economic outcomes. Branches with less favourable attitudes have higher turnover, lower levels of sales, and lower rates of sales growth than branches where workers have more favourable attitudes. Less favourable branch attitudes are also a significant predictor of subsequent branch closings. The study? s results show that there are happy and unhappy workplaces, as well as happy and unhappy workers, with very different patterns of turnover and productivity in these workplaces.
Targeting the slow pathway for atrioventricular nodal reentrant tachycardia: initial results and long-term follow-up in 379 consecutive patients.

OBJECTIVES This study is designed to examine the immediate and short-term outcomes of patients who have undergone slow pathway ablation/modification for atrioventricular nodal reentrant tachycardia. BACKGROUND Targeting the slow pathway has emerged as the superior form of treatment for atrioventricular nodal reentrant tachycardia. This technique has been found effective and is associated with a low complication rate. However, little is known of the long-term outcome of patients undergoing this procedure. METHODS Over a 40-month period the slow pathway was targeted in 379 consecutive patients with proven atrioventricular nodal reentrant tachycardia. The case records of all patients were examined. Accurate follow-up data is available in 96% of patients a mean of 20.6 months after the procedure. RESULTS The initial success rate was 97%. The incidence of complete heart block was 0.8% and the mean fluoroscopy duration was 27.3 min. The recurrence rate was 6.9%. Age, number of pulses and fluoroscopy time were positively associated with either initial failure or recurrence. A total of 11.3% of patients were still taking antiarrhythmic medication at follow-up. CONCLUSIONS Targeting the slow pathway is an effective form of treatment for atrioventricular nodal reentrant tachycardia. The technique has a high initial success rate, a low complication rate and a low recurrence rate at long-term follow-up. Slow pathway modification is associated with similar success rates and recurrence rates as slow pathway ablation and may confer theoretical long-term benefits.
Early Intensive Behavioral Treatment: Replication of the UCLA Model in a Community Setting

ABSTRACT. Although previous studies have shown favorable results with early intensive behavioral treatment (EIBT) for children with autism, it remains important to replicate these findings, particularly in community settings. The authors conducted a 3-year prospective outcome study that compared 2 groups: (1) 21 children who received 35 to 40 hours per week of EIBT from a community agency that replicated Lovaas' model of EIBT and (2) 21 age- and IQ-matched children in special education classes at local public schools. A quasi-experimental design was used, with assignment to groups based on parental preference. Assessments were conducted by independent examiners for IQ (Bayley Scales of Infant Development or Wechsler Preschool and Primary Scales of Intelligence), language (Reynell Developmental Language Scales), nonverbal skill (Merrill-Palmer Scale of Mental Tests), and adaptive behavior (Vineland Adaptive Behavior Scales). Analyses of covariance, with baseline scores as covariates and Year 1-3 assessments as repeated measures, revealed that, with treatment, the EIBT group obtained significantly higher IQ (F = 5.21, p = .03) and adaptive behavior scores (F = 7.84, p = .01) than did the comparison group. No difference between groups was found in either language comprehension (F = 3.82, p = .06) or nonverbal skill. Six of the 21 EIBT children were fully included into regular education without assistance at Year 3, and 11 others were included with support; in contrast, only 1 comparison child was placed primarily in regular education. Although the study was limited by the nonrandom assignment to groups, it does provide evidence that EIBT can be successfully implemented in a community setting.
