A Model Of Competition Between Perpetual Software And Software As A Service, Zhiling GUO, Dan MA 2018 Singapore Management University

A Model Of Competition Between Perpetual Software And Software As A Service, Zhiling Guo, Dan Ma

Research Collection School Of Information Systems

Software as a service (SaaS) has grown to be a significant segment of many software product markets. SaaS vendors, which charge customers based on use and continuously improve the quality of their products, have put competitive pressure on traditional perpetual software vendors, which charge a licensing fee and periodically upgrade the quality of their software. We develop an analytical model to study the competitive pricing strategies of an incumbent perpetual software vendor in the presence of a SaaS competitor. We find that, depending on both the SaaS quality improvement rate and the network effect, the perpetual software vendor adopts one ...

R&D Sensitivity To Asset Sale Proceeds: New Evidence On Financing Constraints And Intangible Investment, Ginka Borisova, James R. Brown 2017 Iowa State University

R&D Sensitivity To Asset Sale Proceeds: New Evidence On Financing Constraints And Intangible Investment, Ginka Borisova, James R. Brown

James R. Brown

We examine the intersection between corporate divestitures of tangible assets and investment in intangible capital (R&D) to provide new tests for the impact financing constraints have on real activity. A positive R&D sensitivity to asset sale proceeds indicates binding financing constraints since cash inflows from tangible asset sales are negatively correlated with productivity shocks and not otherwise connected to intangible investment via non-financial channels. Using a variety of estimation approaches, we document a strong, positive link between cash inflows from fixed asset sales and corporate R&D investment, but only among firms most likely facing binding financing constraints ...

Law, Stock Markets, And Innovation, James R. Brown, Gustav Martinsson, Bruce C. Petersen 2017 Iowa State University

Law, Stock Markets, And Innovation, James R. Brown, Gustav Martinsson, Bruce C. Petersen

James R. Brown

We study a broad sample of firms across 32 countries and find that strong shareholder protections and better access to stock market financing lead to substantially higher long-run rates of R&D investment, particularly in small firms, but are unimportant for fixed capital investment. Credit market development has a modest impact on fixed investment but no impact on R&D. These findings connect law and stock markets with innovative activities key to economic growth, and show that legal rules and financial developments affecting the availability of external equity financing are particularly important for risky, intangible investments not easily financed with ...


Do Financing Constraints Matter For R&D?, James R. Brown, Gustav Martinsson, Bruce C. Petersen 2017 Iowa State University

Do Financing Constraints Matter For R&D?, James R. Brown, Gustav Martinsson, Bruce C. Petersen

James R. Brown

Information problems and lack of collateral value should make R&D more susceptible to financing frictions than other investments, yet existing evidence on whether financing constraints limit R&D is decidedly mixed, particularly in the studies of non-U.S. firms. We study a large sample of European firms and also find little evidence of binding finance constraints when we estimate standard investment-cash flow regressions. However, we find strong evidence that the availability of finance matters for R&D once we directly control for: (i) firm efforts to smooth R&D with cash reserves and (ii) firm use of external equity ...


Overcoming Barriers To Implementing Electronic Health Records In Rural Primary Care Clinics, Patricia Mason, Roger Mayer, Wen-Wen Chien, Judith P. Monestime 2017 Walden University

Overcoming Barriers To Implementing Electronic Health Records In Rural Primary Care Clinics, Patricia Mason, Roger Mayer, Wen-Wen Chien, Judith P. Monestime

The Qualitative Report

Medicare-eligible physicians at primary care practices (PCP) that did not implement an electronic health record (EHR) system by the end of 2015 face stiff penalties. One year prior to the 2015 deadline, approximately half of all primary clinics have not implemented a basic EHR system. The purpose of this phenomenology study was to explore rural primary care physicians and physician assistants’ experiences regarding overcoming barriers to implementing EHRs. Complex adaptive systems formed the conceptual framework for this study. Data were collected through face-to-face interviews with a purposeful sample of 21 physicians and physician assistants across 2 rural PCPs in the ...


Document Sql (Dsql) - An Accessible Yet Comprehensive Ad-Hoc Querying Frontend For Xquery, Arijit Sengupta 2017 Wright State University - Main Campus

Document Sql (Dsql) - An Accessible Yet Comprehensive Ad-Hoc Querying Frontend For Xquery, Arijit Sengupta

Arijit Sengupta

This article presents a declarative query language, Document SQL (DSQL) that has the same look and feel as SQL and was designed by updating the semantics of SQL operations in the structured document domain. At the same time, DSQL was designed such that all queries written in it have equivalent counterparts in XQuery. Thus, by using such a language, users can take advantage of their existing SQL knowledge when writing ad-hoc queries without losing the expressive power of XQuery.

Ransomware In Healthcare Facilities: The Future Is Now, Nikki Spence, David P. Paul III, Alberto Coustasse 2017 Marshall University

Ransomware In Healthcare Facilities: The Future Is Now, Nikki Spence, David P. Paul Iii, Alberto Coustasse

Alberto Coustasse, DrPH, MD, MBA, MPH

Cybercriminals have begun to target the healthcare industry with a type of malware called ransomware, malware that encrypts an infected device and any attached devices or network drives. After encryption, cybercriminals demand a sum of money, also known as a “ransom,” to release the devices from encryption. Without adequate disaster recovery and backup plans, many businesses are forced to pay the ransom. The purpose of this study was to determine the extent of recent ransomware infections in healthcare settings, the risk liabilities and cost associated with such infections, and to determine possible risk mitigation tactics. Financial costs associated with business ...

The Evolution Of Financial Instruments And The Legal Protection Against Counterfeiting: A Look At Coin, Paper, And Virtual Currencies, Ralph E. Mckinney, Lawrence P. Shao, Dale H. Shao, Duane C. Rosenblieb Jr.

Dale H Shao

This essay discusses the requirements for the long-term acceptance of virtual currency as a financial medium of exchange by examination of fundamental criteria associated with the historical development of common tender and selected virtual currencies. The relatively recent appearance of Internet-based transactions have necessitated developing virtual forms of payment such as virtual currencies. According to the Financial Crimes Enforcement Network (“FinCEN”) of the United States Treasury,5 virtual currencies are subject to regulation if that virtual currency has a substitutive purpose for facilitating the exchange of goods and services. Although governments can place stipulations on currencies, users of common tender ...

Forensic Disciplines For Objective Global Strategic Analysis, Dale H. Shao, Lawrence P. Shao, Ralph E. Mckinney Jr.

Dale H Shao

The global nature of investing requires a thorough analysis of the firm to determine the strategic viability of the firm for investment purposes. In addition, businesses are being held more accountable for the statements they make and the actions they take concerning their business. Several forensic disciplines have recently emerged that may supply subjective and objective data that can assist investors in making their final investment decisions and determining if ongoing businesses are truly doing what is in the best interest of their shareholders. Another factor influencing the increase forensic analyses of national and multinational corporations is the increase in ...

Towards A Development Of A Social Engineering Exposure Index (Sexi) Using Publicly Available Personal Information, W. Shawn Wilkerson, Yair Levy, James Richard Kiper, Martha Snyder

KSU Proceedings on Cybersecurity Education, Research and Practice

Millions of people willingly expose their lives via Internet technologies every day, and even those who stay off the Internet find themselves exposed through data breaches. Trillions of private information records flow through the Internet. Marketers gather personal preferences to coerce shopping behavior, while providers gather personal information to provide enhanced services. Few users have considered where their information is going or who has access to it. Even fewer are aware of how decisions made in their own lives expose significant pieces of information, which can be used to harm the very organizations they are affiliated with by cyber attackers ...


A Comparison Of Personal Social Media Risk Perceptions Between Undergraduate Students And Human Resource Professionals, Julio C. Rivera, Jack Howard, Samuel Goh, James Worrell, Paul Di Gangi 2017 University of Alabama, Birmingham

A Comparison Of Personal Social Media Risk Perceptions Between Undergraduate Students And Human Resource Professionals, Julio C. Rivera, Jack Howard, Samuel Goh, James Worrell, Paul Di Gangi

KSU Proceedings on Cybersecurity Education, Research and Practice

This study contrasts the social media risk perceptions of undergraduate students, versus those of certified Human Resource professionals. Social media is widely used by most segments of the population, and particularly among the age group that includes most undergraduate students. Organizations hiring employees are increasingly examining job applicant's social media postings as part of the applicant screening process. In this study we examine how these groups differ in their perceptions of the risks inherent in using social media, and what these differences may mean for students seeking employment. Recommendations are made for raising undergraduate student awareness of these risks.

A Developmental Study On Assessing The Cybersecurity Competency Of Organizational Information System Users, Richard Nilsen, Yair Levy, Steven Terrell, Dawn Beyer

KSU Proceedings on Cybersecurity Education, Research and Practice

Organizational information system users (OISUs) that are open to cyber threats vectors are contributing to major financial and information losses for individuals, businesses, and governments. Moreover, technical cybersecurity controls may be rendered useless due to a lack of cybersecurity competency of OISUs. The main goal of this research study was to propose and validate, using subject matter experts (SMEs), a reliable hands-on assessment prototype tool for measuring the knowledge, skills, and abilities (KSAs) that comprise the cybersecurity competency of an OISU. Primarily using the Delphi methodology, this study implemented four phases of data collection using cybersecurity SMEs for proposing and ...
