‘I Like How You Think’: Similarity as an Interaction Bias in the Investor–Entrepreneur Dyad
Authors: Murnieks Charles Y. , Haynie J. Michael , Wiltbank Robert E. , Harting Troy 
Published: December 2010

abstractInvestigating the factors that influence venture capital decision‐making has a long tradition in the management and entrepreneurship literatures. However, few studies have considered the factors that might bias an investment decision in a way that is idiosyncratic to a given investor–entrepreneur dyad. We do so in this study. Specifically, we build from the literature on the ‘similarity effect’ to investigate the extent to which decision‐making process similarity (shared between the investor and the entrepreneur) might bias or otherwise impact the investor's evaluation of a new venture investment opportunity. Our findings suggest venture capitalists evaluate more favourably opportunities represented by entrepreneurs who ‘think’ in ways similar to their own. Moreover, in the presence of decision‐making process similarity, the impacts of other factors that inform the investment decision actually change in counter‐intuitive ways.
Corporate Governance and the Environment: What Type of Governance Creates Greener Companies?
Authors: Kock Carl J. , Santaló Juan , Diestre Luis 
Published: December 2010

abstractWe build on a stakeholder–agency theoretical perspective to explore the impact of particular corporate governance mechanisms on firm environmental performance. Our empirical evidence shows that several important corporate governance mechanisms such as the board of directors, managerial incentives, the market for corporate control, and the legal and regulatory system determine firms' environmental performance levels. These results suggest that these different governance mechanisms resolve, to some extent, the existing divergence of interests between stakeholders and managers with respect to environmental activities.
Knowledge Acquisition, Network Reliance, and Early‐Stage Technology Venture Outcomes
Authors: Sullivan Diane M. , Marvel Matthew R. 
Published: December 2010

abstractKnowledge acquisition is central to entrepreneurship when explaining successful venturing. However, little is known about how knowledge acquisition during early venture development affects desirable venture outcomes. This study draws on the knowledge‐based view and social network theory to develop and test a conceptual model of knowledge acquisition using a sample of early‐stage technology entrepreneurs operating in university‐affiliated incubators. We examine how an entrepreneur's acquisition of different types of knowledge and reliance on their network for knowledge relate to outcomes of product/service innovativeness and first‐year venture sales. Results suggest that acquiring technology knowledge positively relates to the innovativeness of products/services developed by entrepreneurs. Moreover, entrepreneurs can enhance this positive relationship by relying more on networks for technology knowledge acquisition.
A NEW INSIGHT INTO THE GENDER GAP IN MATH
Authors: Sohn Kitae 
Published: December 2010

ABSTRACTIn the Early Childhood Longitudinal Study Kindergarten Cohort, I find that the gender gap is not uniform across the distribution of math skills and that these quantile‐specific gaps vary with age. Specifically, girls at the top of the distribution initially fall behind boys but manage to catch up later. At the same time, girls in the lower parts of the distribution lose ground. In fifth grade, a gender gap of 0.2 standard deviation, about 2.5 months of schooling, is observed across the entire distribution. Overall, these patterns indicate the possibility that low performing girls become worse and vice versa. These results demonstrate important dynamics of the gap that are relevant for policy, but that the mean gap fails to show.
Moral Mistakes
Authors: Adams Zed 
Published: December 2010

AbstractIs it possible to show that a moral claim is mistaken without taking a moral stand with regard to it? A striking number of contemporary metaethicists suppose that it is. In this paper, I argue against a prominent line of support for this supposition. My goal is to cast suspicion on a general tendency to think that the epistemic standing of moral claims is something that can be assessed from outside the practices of making and critically evaluating moral judgements. I do this by focusing on a widely accepted criterion of competence with regard to the use of moral concepts, the moral supervenience criterion (MSC). This criterion holds that someone who judges two acts or events to be morally different without thinking that he has to identify some non‐particular non‐moral difference between them simply doesn't understand what it is to make a moral judgement. I focus on a paradigmatic example of the sort of mistake in moral judgement that is supposed to support the MSC and argue that it provides no support whatsoever. I then offer my own alternative explanation of this sort of mistake in moral judgement. I conclude with a discussion of why advocates of the MSC are inclined to suppose that it is possible to assess the epistemic standing of a moral claim without oneself taking a moral stand with regard to it.
Support Vector Machines to improve physiologic hot flash measures: Application to the ambulatory setting
Authors: Thurston Rebecca C. , Hernandez Javier , Del Rio Jose M. , De La Torre Fernando 
Published: December 2010

AbstractMost midlife women have hot flashes. The conventional criterion (≥2 μmho rise/30 s) for classifying hot flashes physiologically has shown poor performance. We improved this performance in the laboratory with Support Vector Machines (SVMs), a pattern classification method. We aimed to compare conventional to SVM methods to classify hot flashes in the ambulatory setting. Thirty‐one women with hot flashes underwent 24 h of ambulatory sternal skin conductance monitoring. Hot flashes were quantified with conventional (≥2 μmho/30 s) and SVM methods. Conventional methods had low sensitivity (sensitivity=.57, specificity=.98, positive predictive value (PPV)=.91, negative predictive value (NPV)=.90, F1=.60), with performance lower with higher body mass index (BMI). SVMs improved this performance (sensitivity=.87, specificity=.97, PPV=.90, NPV=.96, F1=.88) and reduced BMI variation. SVMs can improve ambulatory physiologic hot flash measures.
Guilt and pride are heartfelt, but not equally so
Authors: Fourie Melike M. , Rauch Henri G. L. , Morgan Barak E. , Ellis George F. R. , Jordaan Esmè R. , Thomas Kevin G. F. 
Published: December 2010

AbstractWe examined the cardiovascular physiology of guilt and pride to elucidate physiological substrates underpinning the behavioral motivations of these moral emotions. Although both emotions motivate prosocial behavior, guilt typically inhibits ongoing behavior, whereas pride reinforces current behavior. To succeed in eliciting real emotions, we used a novel social interaction task. We found dissociable sympathetic activation during guilt and pride; specifically, Guilt participants experienced prolonged cardiac sympathetic arousal as measured by preejection period (PEP), whereas Pride participants experienced transient non‐cardiac somatic arousal and a shift to low frequency (LF) power in the cardiac spectrogram. This dissociation supports their distinctive motivational functions. Higher self‐reported Behavioral Inhibition System (BIS) sensitivity was furthermore uniquely associated with guilt, supporting its function as a punishment cue.

Published: December 2010

OBJECTIVES:To identify characteristics of nursing home (NH) residents with advanced dementia and their healthcare proxies (HCPs) associated with hospice referral and to examine the association between hospice use and the treatment of pain and dyspnea and unmet needs during the last 7 days of life.DESIGN:Prospective cohort study.SETTING:Twenty‐two Boston‐area NHs.PARTICIPANTS:Three hundred twenty‐three NH residents with advanced dementia and their HCPs.MEASUREMENTS:Data were collected at baseline and quarterly for up to 18 months. Hospice referral, frequency of pain and dyspnea, and treatment of these symptoms was ascertained. HCPs reported unmet needs during the last 7 days of the residents' lives for communication, information, emotional support, and help with personal care.RESULTS:Twenty‐two percent of residents were referred to hospice. After multivariable adjustment, factors associated with hospice referral were nonwhite race, eating problems, HCP's perception that the resident's had less than 6 months to live, and better HCP mental health. Residents in hospice were more likely to receive scheduled opioids for pain (adjusted odds ratio (AOR)=3.16; 95% confidence interval (95% CI)=1.57–6.36) and oxygen, morphine, scopolamine, or hyoscyamine for dyspnea (AOR=3.28, 95% CI=1.37–7.86). HCPs of residents in hospice reported fewer unmet needs in all domains during the last 7 days of the residents' life.CONCLUSION:A minority of NH residents with advanced dementia received hospice care. Hospice recipients were more likely to received scheduled opioids for pain and symptomatic treatment for dyspnea and had fewer unmet needs at the end of life.

Mera S, Tatulescu D, Cismaru C, Bondor C, Slavcovici A, Zanc V, Carstina D, Oltean M. Multiplex cytokine profiling in patients with sepsis. APMIS 2010; 119: 155–63.A major goal for the clinical research in sepsis is mapping the various mediators driving the systemic manifestations of infection. Identifying relevant mediators responsible for the physiological alterations during sepsis may offer diagnostic and therapeutic opportunities. We aimed to explore the novel approach of simultaneously measuring several biomolecules using the multiplex technique and to study its relevance in diagnosing and monitoring septic patients. In 30 patients fulfilling American College of Chest Physicians and the Society of Critical Care Medicine sepsis criteria, we simultaneously measured 17 cytokines during the first 7 days after admission. We analysed the results with respect to the presence of septic shock and survival. Five patients died during the study. We found a significant positive correlation between the monocyte chemotactic protein (MCP)‐1, macrophage inflammatory protein (MIP)‐1β and interleukin (IL)‐8 levels in the first 3 days and Sepsis‐related Organ Failure Assessment score on day 1. Most cytokines showed no significant difference between patients with mild or severe sepsis. The initial levels of MIP‐1β and granulocyte macrophage colony‐stimulating factor were lower in patients with septic shock than in patients without shock. IL‐8 and MCP‐1 early after admission were higher in the non‐survivors (p < 0.05). In the multivariate logistical regression, the initial levels of IL‐8 were the most predictive for fatal outcome. Moreover, IL‐1β, IL‐6, IL‐8, IL‐12, interferon‐γ, granulocyte colony‐stimulating factor and tumour necrosis factor‐α exhibited persistent increases in non‐survivors. The simultaneous evaluation of multiple cytokines in sepsis may identify complex cytokine patterns that reflect the systemic response associated with shock and mortality.
Maxillary sinus vascular anatomy and its relation to sinus lift surgery
Authors: Rosano Gabriele , Taschieri Silvio , Gaudy Jean‐François , Weinstein Tommaso , Del Fabbro Massimo 
Published: December 2010

AbstractObjectives: To investigate the prevalence, location, size and course of the anastomosis between the dental branch of the posterior superior alveolar artery (PSAA), known as alveolar antral artery (AAA), and the infraorbital artery (IOA).Material and methods: The first part of the study was performed on 30 maxillary sinuses deriving from 15 human cadaver heads. In order to visualize such anastomosis, the vascular network afferent to the sinus was injected with liquid latex mixed with green India ink through the external carotid artery. The second part of the study consisted of 100 CT scans from patients scheduled for sinus lift surgery.Results: An anastomosis between the AAA and the IOA was found by dissection in the context of the sinus anterolateral wall in 100% of cases, while a well‐defined bony canal was detected radiographically in 94 out of 200 sinuses (47% of cases).The mean vertical distance from the lowest point of this bony canal to the alveolar crest was 11.25±2.99 mm (SD) in maxillae examined by CT. The canal diameter was <1 mm in 55.3% of cases, 1–2 mm in 40.4% of cases and 2–3 mm in 4.3% of cases.In 100% of cases, the AAA was found to be partially intra‐osseous, that is between the Schneiderian membrane and the lateral bony wall of the sinus, in the area selected for sinus antrostomy.Conclusions: A sound knowledge of the maxillary sinus vascular anatomy and its careful analysis by CT scan is essential to prevent complications during surgical interventions involving this region.

Published: December 2010

AbstractObjectives: This study evaluated the effect of magnesium dietary deficiency on bone metabolism and bone tissue around implants with established osseointegration.Materials and methods: For this, 30 rats received an implant in the right tibial metaphysis. After 60 days for healing of the implants, the animals were divided into groups according to the diet received. Control group (CTL) received a standard diet with adequate magnesium content, while test group (Mg) received the same diet except for a 90% reduction of magnesium. The animals were sacrificed after 90 days for evaluation of calcium, magnesium, osteocalcin and parathyroid hormone (PTH) serum levels and the deoxypyridinoline (DPD) level in the urine. The effect of magnesium deficiency on skeletal bone tissue was evaluated by densitometry of the lumbar vertebrae, while the effect of bone tissue around titanium implants was evaluated by radiographic measurement of cortical bone thickness and bone density. The effect on biomechanical characteristics was verified by implant removal torque testing.Results: Magnesium dietary deficiency resulted in a decrease of the magnesium serum level and an increase of PTH and DPD levels (P≤0.05). The Mg group also presented a loss of systemic bone mass, decreased cortical bone thickness and lower values of removal torque of the implants (P≤0.01).Conclusions: The present study concluded that magnesium‐deficient diet had a negative influence on bone metabolism as well as on the bone tissue around the implants.

Association of Lubricant Use with Women’s Sexual Pleasure, Sexual Satisfaction, and Genital Symptoms: A Prospective Daily Diary Study
Authors: Herbenick Debra , Reece Michael , Hensel Devon , Sanders Stephanie , Jozkowski Kristen , Fortenberry J. Dennis 
Published: December 2010

ABSTRACT

Introduction
Although lubricant use is commonly recommended to women for solo and partnered sexual activities, little is known about women’s use of lubricant or their relationship to sexual pleasure and satisfaction.

Aim
The aim of this study was to assess: (i) how adult women used lubricant during partnered and solo sexual activities; (ii) relations between women’s reports of sexual pleasure and satisfaction and their use of a lubricant during a particular sexual event; and (iii) to what extent lubricant use was associated with subsequent genital symptoms.

Methods
A total of 2,453 women completed a 5-week internet-based, double-blind prospective daily diary study in which they were assigned to use one of six water- or silicone-based lubricants.

Main Outcome Measures
Baseline data included demographics, contraceptive use, and sexual behavior during the 4 weeks prior to study enrollment. Daily diary data included reports of penile–vaginal sex, penile–anal sex, solo sex, lubricant use, lubricant application, ratings of sexual pleasure and satisfaction, and genital symptoms.

Results
Water-based lubricants were associated with fewer genital symptoms compared with silicone-based lubricants. In addition, the use of a water-based or silicone-based lubricant was associated with higher ratings of sexual pleasure and satisfaction for solo sex and penile–vaginal sex. Water-based lubricant use was associated with higher ratings of sexual pleasure and satisfaction for penile–anal sex as compared with no lubricant use.

Conclusion
The water- and silicone-based lubricants used in this study were associated with significantly higher reports of sexual pleasure and satisfaction and rarely associated with genital symptoms.
Evidence of major dry mergers at M* &gt; 2 × 1011M⊙ from curvature in early-type galaxy scaling relations?
Authors: Bernardi Mariangela , Roche Nathan , Shankar Francesco , Sheth Ravi K. 
Published: December 2010

Abstract
For early-type galaxies, the correlations between stellar mass and size, velocity dispersion, surface brightness, colour, axial ratio and colour gradient all indicate that two mass scales, M*= 3 × 1010 and 2 × 1011 M⊙, are special. The smaller scale could mark the transition between wet and dry mergers, or it could be related to the interplay between supernovae (SNe) and active galactic nuclei (AGNs) feedback, although quantitative measures of this transition may be affected by morphological contamination. At the more massive scale, mean axial ratios and colour gradients are maximal, and above it, the colours are redder, the sizes larger and the velocity dispersions smaller than expected based on the scaling at lower M*. In contrast, the colour–σ relation, and indeed, most scaling relations with σ, are not curved: they are well described by a single power law, or in some cases, are almost completely flat. When major dry mergers change masses, sizes, axial ratios and colour gradients, they are expected to change the colours or velocity dispersions much less. Therefore, the fact that scaling relations at σ &gt; 150 km s −1 show no features, whereas the size–M*, b/a–M*, colour–M* and colour gradient–M* relations do, suggests that M*= 2 × 1011 M⊙ is the scale above which major mergers dominate the assembly histories of early-type galaxies.
Demetalation Kinetics of Chlorophyll Derivatives Possessing Different Substituents at the 7‐Position Under Acidic Conditions

Published: December 2010

AbstractConversion of the formyl group at the 7‐position in chlorophyll (Chl) b to the methyl group via the hydroxymethyl group is biologically important in Chl b degradation. To clarify the effects of the 7‐substituents on demetalation properties of chlorophyllous pigments in the early process of Chl b degradation, we report demetalation kinetics of the zinc Chl derivative possessing a 7‐hydroxymethyl group, which is a good model compound of the intermediate molecule in the early process of Chl b degradation, under acidic conditions, and compare its properties with those of zinc Chl derivatives possessing a methyl and a formyl group, which are model compounds of Chls a and b, respectively. Demetalation rate constants of 7‐hydroxymethyl zinc chlorin were much larger than those of 7‐formyl zinc chlorin, but were slightly smaller than those of 7‐methyl zinc chlorin. The activation energy for demetalation reaction of 7‐formyl zinc chlorin was larger than those of other derivatives. Demetalation rate constants of 7‐deformyl‐7‐hydroxymethyl Chl b were also larger than those of Chl b, and were similar to those of Chl a. These indicate that the 7‐hydroxymethyl group in the chlorin macrocycle has a smaller effect on demetalation compared with the 7‐formyl group.
Combination Therapy in Hypertension

Published: December 2010

Editor’s Note: The American Society of Hypertension is publishing a series of Position Papers in their official journals throughout the 2008–2011 years. The following Position Paper originally appeared: JASH. 2010;4:42–50.The goal of antihypertensive therapy is to abolish the risks associated with blood pressure (BP) elevation without adversely affecting quality of life. Drug selection is based on efficacy in lowering BP and in reducing cardiovascular (CV) end points, including stroke, myocardial infarction, and heart failure. Although the choice of initial drug therapy exerts some effect on long‐term outcomes, it is evident that BP reduction per se is the primary determinant of CV risk reduction. Available data suggest that at least 75% of patients will require combination therapy to achieve contemporary BP targets, and increasing emphasis is being placed on the practical tasks involved in consistently achieving and maintaining goal BP in clinical practice. It is within this context that the American Society of Hypertension presents this Position Paper on Combination Therapy for Hypertension. It will address the scientific basis of combination therapy, present the pharmacologic rationale for choosing specific drug combinations, and review patient selection criteria for initial and secondary use. The advantages and disadvantages of single‐pill (fixed) drug combinations and the implications of recent clinical trials involving specific combination strategies will also be discussed.

RESIDENTIAL PROPERTY PRICES IN A SUBMARKET OF SOUTH AFRICA: SEPARATING REAL RETURNS FROM ATTRIBUTE GROWTH
Authors: Els Michael , Von Fintel Dieter 
Published: December 2010

AbstractThe South African residential housing market experienced high growth in the previous decade, in line with international trends. Traditional methods of documenting this trajectory use the average prices of only properties that are sold in given periods and regions. A critical assumption of these approaches is that houses remain homogenous across time and space. This paper constructs a micro‐level hedonic price index to account for changing attributes of heterogenous houses. It illustrates that returns may have been overstated, and that much of the growth recorded in this market is driven by attribute inflation, particularly in the high price segment.
TESTING FOR STATIONARITY OF INFLATION RATES WITH COVARIATES
Authors: Tsong Ching‐chuan , Lee Cheng‐feng 
Published: December 2010

AbstractThis paper distinguishes between the stationarity and nonstationarity of inflation in 18 OECD countries through several unit root tests with covariates. These covariate tests are more powerful than the conventional ones through correlated covariates. Both unit root and stationarity null hypotheses are tested in this study. Our empirical results indicate that the efficient univariate unit root tests fail to reject the unit‐root hypothesis for 15 countries, whereas the covariate tests provide strong evidence in support of mean reversion in inflation for almost all countries. Overall, the findings unveil new evidence in favor of stationarity in international inflation. Policy implications on the empirical results are provided as well.
