Success factors of platform leadership in web 2.0 service business

February 26, 2010 | Comments Off

p class="abstract"div class="Abstract" lang="en"a name="Abs1"/aspan class="AbstractHeading"Abstractnbsp;nbsp;/spandiv class="normal"The purpose of this study is to investigate the critical success factors of platform leadership in the Web 2.0 based service business environment. Because of the lack of theoretical foundation for this topic, we adopted relevant theory and case study analyses. Representative Web 2.0 firms which have developed platform leadership were chosen and analyzed on the basis of previous research on platform strategy through spider web analysis. This study shows that Web 2.0 firms such as Google, Flickr, and Salesforce.com differ in their competitive capabilities for platform leadership. The result of this research suggests that platform leadership in the Web 2.0 era depends on five interdependent dimensions: innovation ability, connectivity, complementarities, efficiency, and network effects. /div /div/pul lispan class="labelName"Content Type /spanspan class="labelValue"Journal Article/span/liliCategory Original Paper/liliDOI 10.1007/s11628-010-0093-3/lilispan class="labelName"Authors/spanul liSang M.

A first report on the shrimp Pontonia sp. and other potential symbionts in the mantle cavity of the penshell Pinna carnea in the Dominican Republic

February 24, 2010 | Comments Off

p class="abstract"div class="Abstract" lang="en"a name="Abs1"/aspan class="AbstractHeading"Abstractnbsp;nbsp;/spandiv class="normal"Examination of the mantle cavity of 310 penshells iPinna carnea/i, collected from seagrass beds in southwestern Dominican Republic, revealed the presence of four species from three phyla as potential symbionts. The shrimp iPontonia/i sp. was found in 178 penshells, the cardinalfish iAstrapogon stellatus/i in 18, an anemone (order Actiniaria) in two, and a pea crab (family Pinnotheridae) in one. The penshell likely provides these organisms with a refuge from predators. It also provides nutrition for shrimp as they consumed food trapped in the mucus secreted by the penshell host. All of the cardinalfish, and 91% of the shrimp, were found in penshells measuring gt;150nbsp;mm in hinge length. At approximately 150nbsp;mm, the shells of iP. carnea/i thicken and so flatten less when the valves are closed. As a result, larger penshells provide more mantle-cavity space for accommodating organisms. Shrimp and cardinalfish size increased with the size of the host penshell. The positive relationship between shrimp size and penshell size, a prevalence of male-female pairs of shrimp and other field observations, suggest that a long-term association exists between shrimp and penshells, and that the mating system of the shrimp involves social monogamy. /div /div/pul lispan class="labelName"Content Type /spanspan class="labelValue"Journal Article/span/liliDOI 10.1007/s13199-010-0050-x/lilispan class="labelName"Authors/spanul liSerge Aucoin, Université Laval Département de biologie and Québec-Océan 1045 Avenue de la Médecine, Local 2078 Quebec City QC G1V 0A6 Canada/liliJohn H.

The Impact of SFAS No. 157 on Commercial Banks

February 24, 2010 | Comments Off

p class="abstract"div class="Abstract" lang="en"a name="Abs1"/aspan class="AbstractHeading"Abstractnbsp;nbsp;/spandiv class="normal"During 2008, U. S. banks were mired in a credit crisis. According to a group of economists and bankers, one cause of the 2008 credit crisis was an accounting rule termed mark-to-market. This rule required banks to write down large portions of their investment portfolios. The purpose of this study is to examine the impact of the mark-to-market model on a sample of banks for the first three quarters of the year 2008. Results indicated that while banks grew by 20% over time, the percentage of assets measured at fair value rose only slightly. Additionally, the results indicated that applying the mark-to-market rule did not reduce the regulatory capital position of banks. /div /div/pul lispan class="labelName"Content Type /spanspan class="labelValue"Journal Article/span/liliDOI 10.1007/s11294-010-9256-1/lilispan class="labelName"Authors/spanul liRichard Schroeder, University of North Carolina at Charlotte Charlotte NC USA/liliDavid Schauer, University of Texas at El Paso Department of Economics and Finance El Paso TX USA/li /ul/li /ulul class="parents" ul class="details" lispan class="header labelName"Journal /spanspan class="labelValue"a href="http://www.springerlink.com/content/112112/"International Advances in Economic Research/a/span/lilispan class="labelName"Online ISSN /spanspan class="labelValue"1573-966X/span/lilispan class="labelName"Print ISSN /spanspan class="labelValue"1083-0898/span/li /ul /ul

Residency Training Program Paradigms for Teaching Robotic Surgical Skills to Urology Residents

February 23, 2010 | Comments Off

p class="abstract"div class="Abstract" lang="en"a name="Abs1"/aspan class="AbstractHeading"Abstractnbsp;nbsp;/spandiv class="normal"The advent of laparoscopic and robotic techniques for management of urologic malignancies marked the beginning of an ever-expanding array of minimally invasive options available to cancer patients. With the popularity of these treatment modalities, there is a growing need for trained surgical oncologists who not only have a deep understanding of the disease process and adept surgical skills, but also show technical mastery in operating the equipment used to perform these techniques. Establishing a robotic prostatectomy program is a tremendous undertaking for any institution, as it involves a huge cost, especially in the purchasing and maintenance of the robot. Residency programs often face many challenges when trying to establish a balance between costs associated with robotic surgery and training of the urology residents, while maintaining an acceptable operative time. Herein we describe residency training program paradigms for teaching robotic surgical skills to urology residents. Our proposed paradigm outlines the approach to compensate for the cost involved in robotic training establishment without compromising the quality of education provided. With the potential advantages for both patients and surgeons, we contemplate that robotic-assisted surgery may become an integral component of residency training programs in the future. /div /div/pul lispan class="labelName"Content Type /spanspan class="labelValue"Journal Article/span/liliDOI 10.1007/s11934-010-0093-9/lilispan class="labelName"Authors/spanul liSonal Grover, Weill Medical College of Cornell University James Buchanan Brady Foundation Department of Urology 525 East 68th Street, Starr 900 New York NY 10065 USA/liliGerald Y.

Local linear hazard rate estimation and bandwidth selection

February 23, 2010 | Comments Off

p class="abstract"div class="Abstract" lang="en"a name="Abs1"/aspan class="AbstractHeading"Abstractnbsp;nbsp;/spandiv class="normal"A new kernel based local linear estimate of the hazard rate, under the random right censorship model is proposed in this article. We study its finite sample and asymptotic properties and prove its asymptotic normality. Then we bring in three popular methods for bandwidth selection to the hazard setting as potential bandwidth choice rules for the estimate. We discuss their practical implementation and through Monte Carlo simulations we use four distributions with different hazard rate shapes to compare their performance over various sample sizes and levels of censoring. /div /div/pul lispan class="labelName"Content Type /spanspan class="labelValue"Journal Article/span/liliDOI 10.1007/s10463-010-0277-6/lilispan class="labelName"Authors/spanul liDimitrios Bagkavos, Information Resources International Rostoviou 17 11526 Athens Greece/li /ul/li /ulul class="parents" ul class="details" lispan class="header labelName"Journal /spanspan class="labelValue"a href="http://www.springerlink.com/content/102845/"Annals of the Institute of Statistical Mathematics/a/span/lilispan class="labelName"Online ISSN /spanspan class="labelValue"1572-9052/span/lilispan class="labelName"Print ISSN /spanspan class="labelValue"0020-3157/span/li /ul /ul
