Be Social! The Impact of Self-Presentation on Peer-to-Peer Accommodation Revenue

Online peer-to-peer platforms empower individual users and facilitate value-oriented exchanges. Personal profiles are the main point of contact with consumers on these platforms. Although individual sellers can use these profiles to market their own products, the optimal communication strategies that maximize their revenues remain uncertain. In line with construal-level theory, a self-presentation strategy that reduces social distance might increase sellers’ revenues. An empirical validation, based on 6,074 Airbnb listings, affirms that self-presentation that evokes social values leads to higher revenues. The length of the self-presentation also exerts a notable impact. Specifically, an inverted U-shaped effect on revenues reaches its peak at 424 words. This research has rich managerial implications, in that it demonstrates how sellers on peer-to-peer platforms can increase their revenues simply by emphasizing social values in their self-presentations.
SUPPLEMENT TO “A COMMENT ON ‘CAN RELAXATION OF BELIEFS RATIONALIZE THE WINNER’S CURSE?:

where Pi is the partition of the states from player i’s point of view. Let Ai be the analogy partitions of the states from player i’s point of view (i = 1 2). For the analogy-based expectation equilibrium, we assume that Ai =Pi for i = 1 2, that is, the private information analogy partition (Jehiel and Koessler (2008, p. 538)). This is visualized in Figure S.1. As Jehiel and Koessler (2008, p. 539) and Eyster and Rabin (2005, p. 1634) noted, this specification coincides with the fully cursed equilibrium (i.e., χ= 1, in Eyster and Rabin (2005) χ-cursed equilibrium). Thus, the analogy-based expectation equilibrium that we construct is also a fully cursed equilibrium. Note that E[Xmax | 10] = 10. For xi ∈X \ {10}, the expected value of the item is
The in vitro investigation of lycopene effects on post-thawed ram sperm

This study was conducted to evaluate the effects of lycopene on quality parameters of cryopreserved ram semen. Semen samples were collected from three Santa Ines rams to form a seminal pool (n = 8). Aliquots from each pool were diluted in Tris-egg yolk extender to create experimental groups containing 0 µM (control), 0.1 µM, 1 µM and 5 µM lycopene. The samples were evaluated for sperm kinetics, integrity of plasma and acrosomal membranes, intracellular reactive oxygen species (ROS) production and lipid peroxidation immediately after thawing and after incubation for two hours at 37 °C. The addition of lycopene had no effect on the parameters that were evaluated at the time of thawing when compared with the control. However, after incubation, the groups with added lycopene showed a decrease in progressive motility. All experimental groups showed a significant reduction in linearity and straightness following incubation. Furthermore, the 5 µM lycopene group showed a decrease in wobble and an increase in amplitude of lateral head displacement. In conclusion, the addition of lycopene to the freezing extender of ram semen affected the kinetics parameters of cryopreserved spermatozoa after a two-hour incubation period.

Do university entrepreneurship programs promote entrepreneurship?

Abstract Recently, many universities have developed entrepreneurship programs. However, relatively little is known about their impacts. This paper examines how entrepreneurship initiatives affect entrepreneurial activity using a unique survey that asks about the entrepreneurship activities of Stanford alumni. We examine the two major initiatives that were established in the mid 1990s the Stanford Center for Entrepreneurial Studies at the Business School and the Stanford Technology Ventures Program at the Engineering School. OLS regressions find that program participation is positively related to entrepreneurship activities. We utilize the introduction of each school’s program as an instrument for program participation. Overall, the findings imply that university entrepreneurship programs may not increase entrepreneurship, but help students to better identify their potential as entrepreneurs and improve the quality of entrepreneurship.
Speechmath IPTV’s Verification System

In today's world, IPTV services are considered among the most prevalent technologies. One emerging challenge is the parental control. This paper demonstrates how to provide users with a mathematical quiz depending on the suitable program's age. The goal is to determine the answer from the user’s voice using the google speech recognition API. This work produces authentication results for two different age groups. All results are presented after viewer groups were tested with the same programs broadcasted over the IPTV service. Recommendations and a final decision are provided depending on the results obtained from this work.
Investor attention and commonalities across asset pricing anomalies

We comprehensively exam the effects of investor’s attention of individual stocks on daily financial market anomalies. The weekday effect of anomalies coincides with the seasonality of investor attention. Using stocks reaching price limits as exogenous shocks, we find that most of anomalies are stronger for stocks attracting relatively higher investor attention. Investor attention may help to explain financial market anomalies beyond investor sentiment, because noise traders invest in stocks that catch excessive attention and make arbitrage hard and mispricing persistent. 1 We are grateful for helpful comments from Justin Birru, Wei Huang, Yuqin Huang, Fuwei Jiang, Raymond Kan, Hong Liu, Baolian Wang, Tianyi Wang, Weixing Wu, Xueyong Zhang, and participants at the Central University of Finance and Economics, and University of International Economics and Business.

Electrocardiographic predictors of clinical outcome in ST-elevation myocardial infarction

Malignant ventricular arrhythmias, particularly ventricular fibrillation (VF), remain an important contributor to mortality in ST-elevation myocardial infarction (STEMI). The size of myocardial injury is one more important factor influencing the prognosis of STEMI patients. The search for new non-invasive markers, which can be relatively simply calculated using conventional ECG recording and can predict the degree of myocardial injury and impending VF, is promising. This work is aimed at investigating cardiac repolarization and depolarization abnormalities and predictors and prognosis of ventricular arrhythmias during the course of STEMI. The thesis is composed of the experimental part (Studies I, II, III) and clinical register-based retrospective studies (Studies IV and V). Closed-chest porcine model of myocardial infarction (MI) was used in the experimental part. Occlusion of left descending artery (LAD) lasted 40 minutes and was followed by reperfusion, and ECG was continuously recorded. QRSduration and morphology, dynamics of ST-segment and T-wave alternans (TWA) were calculated, and myocardial area at risk (MaR) and infarct size (IS) were assessed. Predictors and prognostic impact of early VF in STEMI was assessed in a register-based study of 1,718 consecutive patients admitted for primary PCI during 2007-2009 who were followed up for one year. In experimental MI, the maximal level of TWA during occlusion period was associated with both MaR and IS (Study II). Rapid and marked transient increase in QRS duration associated with appearance of J-wave pattern predicted impending VF in acute ischemia (Study III). Restoration of blood flow in infarct-related artery was accompanied by reperfusion peak in all animals, and the magnitude of ST elevation at reperfusion peak was associated with infarct size (Study I). In clinical studies IV and V, the risk of VF in acute period of STEMI was higher in patients with MI history, cardiovascular risk factors such as smoking and left main stenosis, resulting in a large infarct area. Besides MI history and left main stenosis, the risk of VF at reperfusion was associated with inferior localization of STEMI, hypokalemia, high ST-elevation and shorter symptom-toballoon time. The magnitude of ST-elevation before PCI for STEMI independently predicted reperfusion VF. Patients successfully resuscitated after VF and alive at 48 hours had higher in-hospital mortality (12% vs. 2%, p<0.001). However, in VF patients who were discharged alive, 1-year mortality did not differ compared with patients without VF (Less)
Tuple space explosion: a denial-of-service attack against a software packet classifier

Efficient and highly available packet classification is fundamental for various security primitives. In this paper, we evaluate whether the de facto Tuple Space Search (TSS) packet classification algorithm used in popular software networking stacks such as the Open vSwitch is robust against low-rate denial-of-service attacks. We present the Tuple Space Explosion (TSE) attack that exploits the fundamental space/time complexity of the TSS algorithm. TSE can degrade the switch performance to 12% of its full capacity with a very low packet rate (0.7 Mbps) when the target only has simple policies such as, "allow some, but drop others". Worse, an adversary with additional partial knowledge of these policies can virtually bring down the target with the same low attack rate. Interestingly, TSE does not generate any specific traffic patterns but only requires arbitrary headers and payloads which makes it particularly hard to detect. Due to the fundamental complexity characteristics of TSS, unfortunately, there seems to be no complete mitigation to the problem. As a long-term solution, we suggest the use of other algorithms (e.g., HaRP) that are not vulnerable to the TSE attack. As a short-term countermeasure, we propose MFCGuard that carefully manages the tuple space and keeps packet classification fast.
AVALIAÇÃO DA MICRODENSIDADE VASCULAR COMO FATOR PROGNÓSTICO EM SARCOMAS DE TECIDOS MOLES EM CANINOS E FELINOS

SILVEIRA, Matheus Folgearini. Microvessel density evaluation as a prognostic factor in canine and feline soft tissue sarcomas. 2009. 60f. Dissertação (Mestrado) Programa de Pós-Graduação Veterinária. Universidade Federal de Pelotas, Pelotas. Soft tissue sarcomas are mesenchymal origin neoplasms collectively classified according to histological characteristics and biological behaviour similiarities. Various neoplasms are included in this major group, as fibrosarcoma, peripheral nerve sheath tumor, myxosarcoma, liposarcoma, leiomyosarcoma, rhabdomiosarcoma, malignant fibrous histiocytoma, synovial cell sarcoma and undifferentiated sarcoma. The microvessel density measure has been applied to investigate tumor angiogenesis in many neoplasms. The objectives of this study were to evaluate de microvessel density in canine and feline soft tissue sarcomas and compare the general vessel measurement area and intense vascular areas – hot spot. Those data were compared to usually applied prognostic factors like mitotic index, necroses presence and amount and cellular differentiation. Soft tissue sarcomas were collected in Laboratório Regional de Diagnóstico da Universidade Federal de Pelotas from 1978 to 2008 among canine and feline necropsies and biopsies. In a total of 1668 neoplasms cases during this period, 100 were soft tissue sarcomas, 87 canine and 13 feline. Sex prevalence was not observed in the analyzed species. The major prevalence in canine were hemangiosarcomas (n=34) and fibrosarcomas (n=20), being the mongrel dogs (n=35) most. The large breeds presented major frequence (n=22), followed by medium size (n=16) and small sized breeds (n=9). In feline population, there were not accentuated prevalence, exciding hemangiosarcomas (n=4) and fibrosarcomas (n=4). In those 100 cases, 39 paraffin blocks were obtained, being 36 canine and 3 feline, mostly mongrel specimens, with 9,21(±2,99) medium age. The general vascular and hot spot areas were significantly correlated (r=0,98; p<0,01). The mitotic index between areas were in those areas (r=0,95, p<0,01). Hemangiosarcomas presented major vascular media in the techniques, followed by muscular sarcomas and fibrosarcomas (p<0,05). The microvessel density in soft tissue sarcomas do not present correlation to other prognostic factor usually applied. Hot spot areas can be utilized to determine the vascular degree and mitotic index in soft tissue sarcomas.

Dissolution rate enhancement of bicalutamide by adsorption process

The aim of the present research was to enhance the dissolution rate of poorly water soluble drug, bicalutamide by adsorption process. Bicalutamide is an antiandrogen agent used in the treatment of prostate cancer. To improve the dissolution rate of the drug, hydrophilic carrier like povidone K30 and adsorbent like magnesium aluminum silicate were used as dissolution rate enhancers. Granules of bicalutamide were prepared by wet granulation technique by using magnesium aluminum silicate and povidone K 30 either alone or in combination at different concentrations. The granules were evaluated for packing and compression properties. The granules were compressed into tablets, and different tableting parameters were investigated. The dissolution profile of the tablets was also evaluated and compared with the marketed product. From the dissolution profile, it was observed that the carrier ratio of 3:1 of magnesium aluminum silicate to povidone K 30 exhibited higher dissolution rate than the other formulations. Key words: Bicalutamide, magnesium aluminum silicate, adsorption, povidone K 30.
Early Clinical Studies on Target Specific Anticancer Agents

textabstractThis thesis presents the results of a number of phase I studies with new target specific growth inhibitory or cytostatic anticancer agents, administered as single agent or in combination with cytotoxic chemotherapy. The new target specific agents studied are an epidermal growth factor receptor tyrosine kinase inhibitor, a farnesyltransferase inhibitor and an angiogenesis inhibitor, respectively. Whereas the first two agents act on targets that are located in the cancer cell wall and within the cytoplasm, respectively the third agent is specifically developed to inhibit the formation of new blood vessels in the peritumoral stroma.
Board Independence and Firm Value: Evidence from Closed-End Funds

I use a sample of closed-end funds to document a positive relation between board independence and firm value. Previous literature has largely disagreed on the impact of board independence on firm value, with most studies simply concluding that there is no effect. The disagreement has largely stemmed from endogeneity concerns, which I address in this paper using two distinct instrumental variables approaches. Lastly, I find that independent boards are also associated with lower expense ratios, fewer rights offerings, and additional share repurchases. JEL Classification: G30, G34, G39
Relationship Between the Brent Oil Price and the US Dollar Exchange Rate

This article deals with an analysis of the relationship between the Brent oil price and the US dollar price. This paper analyses the development of the intensity and direction of dependence between the nominal effective exchange rate of the US dollar and the price of Brent oil and other commodities, such as industrial metals, agricultural commodities, gold (including jewellery and platinum) in the period from January 1994 to April 2018. The next section tests the hypothesis that there is a short-term relationship between the effective US dollar exchange rate and the oil price. The last part of the article deals with the question whether there is a long-term relationship between these variables: Brent oil price, effective exchange rate of the US dollar, industrial production index in OECD countries, three-month treasury bill, US ending stocks of crude oil, US percent utilization of refinery operable capacity and the price of ethanol.
The Man Who Sewed His Mouth and Ears: A Case Report

Abstract It is obvious that the case of sewing lips and ears, a form of pathological behavior although not a disruptive behavior is not frequent. Especially the fact that the case was taken from the prison, and brought to emergency accompanied by gendarmes several times, makes the shocking situation even more interesting. This presentation was made to reflect the condition of the convicted patient who sewed both his lips 3 more times with a sewing needle a month ago, seven days ago and 4 days ago and brought to emergency; additionally sewed his ears and brought to emergency for the fourth time writing his wish on a small piece of paper telling that he wanted to see a psychiatrist and whose treatment and examination were done by an emergency specialist and a psychiatrist.
2-D analytical winding losses model of micro-inductor

Since the magnetic field distribution in winding window of thin film micro-inductor with closed magnetic core has obvious 2-D characteristics, the accuracy of 1-D analytical model for its winding AC losses is poor. The magnetic field of the micro-inductor is analyzed deeply to show that its distribution along the winding edge does not change with frequency. According to the analysis result, the magnetic field strength around the winding edge is calculated with the Ampere's law. And the 2-D magnetic field is decomposed into an x component and y component in rectangular coordinates. Then based on the superposition and uniqueness law of magnetic field, a 2-D analytical winding losses model of thin film micro-inductor is proposed. Finally, the finite element analysis (FEA) simulation verified the loss model to have high accuracy under wide exciting current frequency and the loss model can be used easily.
Guitar String Separation Using Non-Negative Matrix Factorization and Factor Deconvolution

Guitar string separation is a novel and complicated task. Guitar notes are not pure steady-state signals, hence, we hypothesize that neither Non-Negative Matrix Factorization (NMF) nor Non-Negative Matrix Factor Deconvolution (NMFD) are optimal for separating them. Therefore, we separate steady-state and transient parts using Harmonic-Percussive Separation (HPS) as a preprocessing step. Then, we use NMF for factorizing the harmonic part and NMFD for deconvolving the percussive part. We make use of a hexaphonic guitar dataset which allows for objective evaluation. In addition, we compare several types of time-frequency mask and introduce an intuitive way to combine a binary mask with a ratio mask. We show that the HPS mask type has an effect on source estimation. Our proposed method achieved results comparable to NMF without HPS. Finally, we show that the optimal mask at the final separation stage depends on the estimation algorithm.
LATE NEOLITHIC AND EARLY BRONZE AGE OCCUPATION AT MIDDLE WALLOP, HAMPSHIRE By david GilbeRt, John MooRe and claRe RobeRtS with contributions by fRanceS RayMond and adRian M. chadwicK

John Moore Heritage Services carried out an archaeological excavation in a broadly square-shaped field 3.34 hectares in extent, on agricultural land at Middle Wallop (NGR SU 2948 3896, Fig. 1). Located within the southern part of the Wallop Defence Systems site, the work was conducted prior to the construction of a new manufacturing building. The underlying geology was the Seaford Chalk formation of Upper Chalk, and the elevation varied between approximately 74m above Ordnance Datum (OD) at the south-western side of the site to 82m OD on the eastern side.
ON THE EXISTENCE OF KAM TORI FOR PRESYMPLECTIC

We prove the existence of a torus that is invariant with respect to the flow of a vector field that preserves the presymplectic form in an exact presymplectic manifold. The flow on this invariant torus is conjugate to a linear flow on a torus with a Diophantine velocity vector. The proof has an “a posteriori” format, the the invariant torus is constructed by using a Newton method in a space of functions, starting from a torus that is approximately invariant. The geometry of the problem plays a major role in the construction by allowing us to construct a special adapted basis in which the equations that need to be solved in each step of the iteration have a simple structure. In contrast to the classical methods of proof, this method does not assume that the system is close to integrable, and does not rely on using action-angle variables.
Urban growth and waste management optimization towards â€ ̃zero waste cityâ€TM

1877-9166/$ see front matter Crown Copyright 2 doi:10.1016/j.ccs. 2011.11. 007 ⇑ Corresponding author. Tel. : +61 08 83027372; fax E-mail addresses: zamau001@mymail.unisa. ed Lehmann@unisa.edu. au (S. Lehmann). 1 Tel. :+61 8302 0654; fax: + 61 8 8302 0211. Today, many developed cities such as Stockholm, and Adelaide are aiming to transform their current waste management practice into a more efficient and sustainable way, called zero waste practice. Increasingly people move from rural to urban environments due to the economic activities and quality of life provided to inhabitants, causing cities to expand. Over-crowded cities are compromising the quality of urban life due to their rapid growth and ever-increasing generation of waste. The concept of the ‘‘zero waste city” includes a 100% recycling rate and recovery of all resources from waste materials. However, transforming current over-consuming cities to zero waste cities is challenging. Therefore, this study aims to understand the key drivers of waste management and the challenges, threats, and opportunities in transforming traditional waste streams and optimizing practices toward zero waste practices. Part of this study is an in-depth case analysis of waste management systems in two cities, Adelaide and Stockholm. Cities from high consuming countries, such as Australia and Sweden, have been analyzed based on five waste management contexts: social, economic, political, technological, and environmental. In addition, key drivers are identified. Both Adelaide and Stockholm have the vision to become ‘‘zero waste cities”. The study concludes that strategies based on tools, systems, and technologies can assist cities in their transformation into ‘‘zero waste cities”; however, they must also be affordable, practicable, and effective within their local regulatory framework.

Industrial Organization, Order Internalization, and Invariance

We present a one-period model of oligopolistic strategic trading among symmetric traders who agree to disagree about the precision of their private signals. We derive several invariance relationships relating the number of firms, number of firmâs employees, average trade size, price impact, and pricing accuracy to dollar volume and returns volatility. Since a substantial part of order flow is often internalized within firms and does not reach the marketplace, invariance relationships can be modified to account for internalized order flow.
