Amplification And Suppression Of Internal Waves By Tides Over Variable Bottom Topography, Vasiliy Vlasenko, Nataliya Stashchuk

School of Biological and Marine Sciences

The energy exchange between internal waves and barotropic currents over inclined bottom topography is studied theoretically and in the framework of the numerical model. The energy balance equation derived for a continuously stratified fluid predicts that energy can either be transferred toward or away from the internal wave depending on the direction of propagation of both the wave and current. Four scenarios of wave-flow interaction over the inclined bottom were identified. An internal wave extracts energy from the background tidal flow during its propagation upslope-upstream or downslope-downstream and its amplitude grows. The wave loses energy propagating downslope-upstream or upslope-downstream and …

Maternal Condition And Facultative Sex Ratios In Populations With Overlapping Generations., L.E. Schwanz, J.G. Bragg, Eric Charnov

Biology Faculty & Staff Publications

Facultative investment in offspring sex is related to maternal condition in many organisms. In mammals, empirical support for condition-dependent sex allocation is equivocal, and there is some doubt as to theoretical expectations. Much theory has been developed to make predictions for condition-dependent sex ratios in populations with discrete generations. However, the extension of these predictions to populations with overlapping generations (OLGs; e.g., mammals) has been limited, leaving doubt as to the specific prediction for maternal-condition-dependent sex ratios in mammals. We develop a population genetics model that incorporates maternal effects on multiple offspring fitness components in a population with OLGs. Using …

Ethical Attitudes Of Business Information Systems Students: An Empirical Investigation, Leila Halawi, Silva Karkoulian

Publications

This paper discusses attitudes toward ethical issues in information systems. Approximately 150 subjects were drawn from two populations: full-time undergraduate business information systems students and full-time master’s students. The subjects read a subset of six ethical scenarios. Hypotheses were tested for significant differences between the undergraduate students’ beliefs and those of graduate students, and female and male students who responded to the same scenarios.

Which Theory Applies: An Analysis Of Information Systems Research, Leila Halawi, Richard Mccarthy

Publications

Research in information systems has rapidly expanded during its relatively brief existence. IT offers organizations a fundamental decision-enhancing environment that extends new opportunities, therefore producing thriving, competitive firms, adding business value and offering valuable products and services to customers. Research within the IT domain has produced several new theories, some of which have been used to help explain and predict end-user use of technologies. We provide a comprehensive overview of the major IT theories and review their theoretical fundamentals.

Parameter Inference Of Queueing Models For It Systems Using End-To-End Measurements, Laura Wynter, Cathy H. Xia, Fan Zhang

Research Collection School Of Computing and Information Systems

As Information Technology (IT) matures and expands in the scope of available applications, IT systems increase at a fascinating rate in both size and complexity. For example, today, a typical Web service hosting center may have hundreds of nodes and dozens of different applications simultaneously running on it. Each of the nodes in turn has often multiple processors and layered caches. These nodes make use of both local and shared storage systems. The size and complexity of such systems make performance modeling much more difficult, if at all tractable. Detailed modeling, fine tuning and accurate analysis can be carried out …

Systems analysis and design has been as critical building block in Information Systems (IS) education since the inception of the IS major. Whether it is taught using the traditional or "structured approach or the object-oriented approach, it exposes students to the different methods, tools, and techniques used in developing new systems, develops students analytical and problem-solving skills, teaches fact-finding and data gathering techniques, and provides teamwork skills. All of these are valuable skills for systems analysts. This paper introduces the reader of this special issue on systems analysis and design education to the issue, discusses the two approaches to teaching …

Grid-Partition Index: A Hybrid Approach To Nearest-Neighbor Queries In Wireless Location-Based Services, Baihua Zheng, Jianliang Xu, Wang-Chien Lee, Dik Lun Lee

Research Collection School Of Computing and Information Systems

Traditional nearest-neighbor (NN) search is based on two basic indexing approaches: object-based indexing and solution-based indexing. The former is constructed based on the locations of data objects: using some distance heuristics on object locations. The latter is built on a precomputed solution space. Thus, NN queries can be reduced to and processed as simple point queries in this solution space. Both approaches exhibit some disadvantages, especially when employed for wireless data broadcast in mobile computing environments. In this paper, we introduce a new index method, called the grid-partition index, to support NN search in both ondemand access and periodic broadcast …

The Impact Of Financial Market And Resale Market On Firm Strategies, Zhiling Guo, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

The ever-increasing use of information technology (IT) in business transactions greatly expands firms? exposure to different electronic markets. This paper provides a framework to understand how firms can leverage different strategies across external financial markets and an internal resale market to improve overall profitability. We develop a model in which a group of risk-averse retailers sell a homogeneous product to their respective uncertain consumer markets. We study a scenario where an internal resale market can be constructed among the retailers and outside financial markets can be used to improve their ability to manage uncertainty. We identify strategies for retailers operating …

Efficient Mining Of Group Patterns From User Movement Data, Yida Wang, Ee Peng Lim, San-Yih Hwang

Research Collection School Of Computing and Information Systems

In this paper, we present a new approach to derive groupings of mobile users based on their movement data. We assume that the user movement data are collected by logging location data emitted from mobile devices tracking users. We formally define group pattern as a group of users that are within a distance threshold from one another for at least a minimum duration. To mine group patterns, we first propose two algorithms, namely AGP and VG-growth. In our first set of experiments, it is shown when both the number of users and logging duration are large, AGP and VG-growth are …

Managing Fisheries Resources In Kaptai Reservoir, Bangladesh, Kku Ahmed, S Rahman, Su Ahammed

School of Geography, Earth and Environmental Sciences

This paper examines the various challenges facing the development of fisheries resources in Kaptai reservoir, Bangladesh. The reservoir has undergone major changes in its catch composition since impoundment. Production records show a declining trend in the productivity of high-value fish. A host of managerial, socioeconomic and environmental factors are responsible for the underutilization of the reservoir's potential to provide high-value freshwater fish. These include deterioration of the natural breeding ground, environmental damage, poor implementation of regulations, inefficient fish farming technology and poor management practices. These constraints are discussed and possibilities for future improvements are suggested.

What Independent Directors Should Expect From Inside Directors: Smith V. Van Gorkom As A Guide To Intra-Firm Governance, Cheryl L. Wade

Faculty Publications

(Excerpt)

Smith v. Van Gorkom is the watershed case in which the board of a public company was held liable for breach of its fiduciary duty of care. The board of Trans Union Corporation (Trans Union) approved the company's sale to Jay Pritzker after a twenty-minute oral presentation by Chief Executive Officer Jerome Van Gorkom. The board spent only two hours considering Pritzker's offer before approving it. The directors received no notice or information before the meeting that its purpose was to approve the company's sale to Pritzker, nor did they receive anything in writing describing the proposed deal. No …

Plagiarism In Cyberspace: Learning The Rules Of Recycling Content With A View Towards Nurturing Academic Trust In An Electronic World, Deborah R. Gerhardt

Richmond Journal of Law & Technology

Plagiarism is an issue of trust. If we respect honor codes, we gain the comfort of knowing that what we read is spoken in the voice of the author and what we write will not be misrepresented as someone else’s original work. Are these simple comforts anachronistic? Perhaps. Acts of plagiarism among students are on the rise, and recently, a series of famous academics, historians, journalists, and even a Tony-award nominated playwright have been accused of plagiarism. If our academic communities hope to reverse this trend, we must reflect on how and why plagiarism occurs and what we can do …

How Does My Work Become Our Work? Dilution Of Authorship In Scientific Papers, And The Need For The Academy To Obey Copyright Law, Sean B. Seymore

Richmond Journal of Law & Technology

Professors enjoy a world of extensive institutional autonomy and individual academic freedom. Universities and courts defer to a professor’s judgment for “genuinely academic decisions” unless they depart from academic norms. Universities, courts, and professional societies should intervene, however, when academic norms and custom do not comport with the law.

E-Prescribing In A Changing Legal Environment, Jeff Todd

Richmond Journal of Law & Technology

Perhaps nothing permeates modern American society as much as prescription drugs. Evidence of this exists not just in television and magazine ads extolling the promises of Viagra and Nexium, but also in a few statistics. First, forty-six percent of Americans use at least one prescription drug daily. Further, in 2001, 3.1 billion prescriptions were issued in the United States at a cost of $132 billion. That amount is projected to increase to $414 billion by 2014.3 Such numbers explain the intensity of the recent political and legal debates surrounding prescription drugs, such as the importation of American pharmaceuticals from Canada …

The Impact Of The Proposed Federal E-Discovery Rules, Thomas Y. Allman

Richmond Journal of Law & Technology

Because of a conviction that e-discovery presents unique issues requiring uniform national rules, the Judicial Conference of the United States (“Judicial Conference”) has recommended and the Supreme Court has approved a number of amendments to the Federal Rules of Civil Procedure (“Proposed Rules”), which are scheduled to go into effect at the end of 2006.

A Duty Everlasting: The Perils Of Applying Traditional Doctrines Of Spoliation To Electronic Discovery, Michael R. Nelson, Mark H. Rosenberg

Richmond Journal of Law & Technology

Amendments to the Federal Rules of Civil Procedure regarding electronic discovery are expected to take effect on December 1, 2006. These amendments are designed to alleviate the burden, expense and uncertainty that has resulted from the application of traditional discovery principles in the electronic age. These principles worked well in an era where discovery was primarily limited to the production of paper documentation, but have proved unworkable when applied to the discovery of electronic data, particularly in the “corporate world,” where even the most routine business discussions are captured in electronic format.5

Shifting Burdens And Concealing Electronic Evidence: Discovery In The Digital Era, Rebecca Rockwood

Richmond Journal of Law & Technology

In the twenty-first century, persons involved in the legal profession will be forced to confront technological issues. Computers and technology have pervaded every aspect of society, and the legal system is no exception. The discovery process is a dramatic example of how lawyers and courts strain to keep up with technological advances. Traditional discovery practices have been severely overhauled as electronic information becomes increasingly prevalent. What was once a simple discovery request can now become an overwhelming task, as defendants must wade through a plethora of electronic documents in an attempt to comply with the court’s discovery orders.
