An Empirical Analysis Of Mobile Voice Service And Sms: A Structural Model, Youngsoo Kim, Rahul Telang, William B. Vogt, Ramayya Krishnan Jan 2010

An Empirical Analysis Of Mobile Voice Service And Sms: A Structural Model, Youngsoo Kim, Rahul Telang, William B. Vogt, Ramayya Krishnan

Research Collection School Of Computing and Information Systems

In addition to the wireless telephony boom, a similar exponentially increasing trend in wireless data service—for example, short message service (SMS)—is visible as technology advances. We develop a structural model to examine user demand for voice service and SMS. Specifically, we measure the own- and cross-price elasticities of these services. The cross-price elasticity is of significant importance because marketing activities are critically influenced by whether the goods are substitutes or complements. The research context poses significant econometric challenges due to three-part tariffs and sequential discrete plan choice and continuous quantity choice decisions. Using detailed individual consumption data of more than …

Affectivity And The Nature Of The Sage: Gleanings From A Tang Daoist Master, Alan Kam Leung Chan Jan 2010

Affectivity And The Nature Of The Sage: Gleanings From A Tang Daoist Master, Alan Kam Leung Chan

Research Collection College of Integrative Studies

This essay explores the place of qing in conceptions of the nature and being of the sage, focusing on the Tang Daoist master Wu Yun. What it seeks to show is that assumptions about the attainability of “sagehood” and the “nature” (xing) of human beings inform the interpretation of qing. In this context, the idea that the sage is quintessentially wuqing, marked by the absence of desire and emotions, will be examined. I will close with a comparative note on a Confucian account of the same period—namely, the Fuxing shu by Li Ao.

Keep It Simple With Time: A Reexamination Of Probabilistic Topic Detection Models, Qi He, Kuiyu Chang, Ee Peng Lim, Arindam Banerjee Jan 2010

Keep It Simple With Time: A Reexamination Of Probabilistic Topic Detection Models, Qi He, Kuiyu Chang, Ee Peng Lim, Arindam Banerjee

Research Collection School Of Computing and Information Systems

Topic detection (TD) is a fundamental research issue in the Topic Detection and Tracking (TDT) community with practical implications; TD helps analysts to separate the wheat from the chaff among the thousands of incoming news streams. In this paper, we propose a simple and effective topic detection model called the temporal Discriminative Probabilistic Model (DPM), which is shown to be theoretically equivalent to the classic vector space model with feature selection and temporally discriminative weights. We compare DPM to its various probabilistic cousins, ranging from mixture models like von-Mises Fisher (vMF) to mixed membership models like Latent Dirichlet Allocation (LDA). …

A Legal And Economic Analysis Of The Conflict Of Property Rights On Generic Names: Based On The “Little Sheep” Trademark Dispute, Wei Zhang, Ming Yang Jan 2010

A Legal And Economic Analysis Of The Conflict Of Property Rights On Generic Names: Based On The “Little Sheep” Trademark Dispute, Wei Zhang, Ming Yang

Research Collection Yong Pung How School Of Law

自我国2001年修订《商标法》接受了"第二含义理论"——即承认"共用名称"通过使用可以产生显著性,从而得以注册为商标(第11条第2款)——以来,相关司法实践中的争议一直不断,尤其是引起广泛争议的"小肥羊"商标案的发生,使得人们开始担忧,允许"共用名称"注册为商标而给经营者带来的激励,不免引发过度投资,从而导致无效率的竞争和不公平的结果。但是,从"共用名称"之本质的经济分析出发,我们可以发现,允许该标识注册为商标实际上是避免出现"公地灾难"的有效率的做法。另外,商标法上相关制度的设置,也不会产生学者们所担心的不公平的结果。

Managing Female Foreign Domestic Workers In Singapore: Economic Pragmatism, Coercive Legal Regulation, Or Human Rights, Eugene K. B. Tan Jan 2010

Managing Female Foreign Domestic Workers In Singapore: Economic Pragmatism, Coercive Legal Regulation, Or Human Rights, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

Singapore's immigration discourse is deeply influenced by its need to “right-size” its population. As a society that has and remains in need of immigration, contemporary immigration and globalization have rigorously challenged the conventional thinking and understanding of citizenship, as well as notions of who belongs and who does not. Nevertheless, international marriages and pervasive in-and out-migration for purposes of employment, study, and family, conspire to make more pronounced the decoupling of citizenship and residence in Singapore. This transnational dimension sits uncomfortably with the policy makers' desire for, and the imperatives of, state sovereignty, control, and jurisdiction.Although one quarter of people …

Singapore And The Universal Periodic Review: An Unprecedented Human Rights Assessment, Mahdev Mohan

Research Collection Yong Pung How School Of Law

Singapore will soon submit a national report to and subsequently appear before the UN Human Rights Council for a universal periodic review of its human rights laws and practices. This review will elicit a rare and unprecedented expression of whether and how Singapore feels it has adhered to international human rights law, and ways in which it may further refine or calibrate its domestic practices. This article seeks to identify Singapore’s human rights achievements; highlight challenges it should be prepared to address; and recommend measures it should adopt to promote human rights.

Structure And Content Semantic Similarity Detection Of Extensible Markup Language Documents Using Keys, Waraporn Viyanon Jan 2010

Structure And Content Semantic Similarity Detection Of Extensible Markup Language Documents Using Keys, Waraporn Viyanon

Doctoral Dissertations

"XML (eXtensible Mark-up Language) has become the fundamental standard for efficient data management and exchange. Due to the widespread use of XML for describing and exchanging data on the web, XML-based comparison is central issues in database management and information retrieval. In fact, although many heterogeneous XML sources have similar content, they may be described using different tag names and structures. This work proposes a series of algorithms for detection of structural and content changes among XML data. The first is an algorithm called XDoI (XML Data Integration Based on Content and Structure Similarity Using Keys) that clusters XML documents …

Exploring Query Optimization In Programming Codes By Reducing Run-Time Execution, Venkata Krishna Suhas Nerella, Swetha Surapaneni, Sanjay Kumar Madria, Thomas Weigert Jan 2010

Exploring Query Optimization In Programming Codes By Reducing Run-Time Execution, Venkata Krishna Suhas Nerella, Swetha Surapaneni, Sanjay Kumar Madria, Thomas Weigert

Computer Science Faculty Research & Creative Works

Object querying is an abstraction of operations over collections, whereas manual implementations are performed at low level which forces the developers to specify how a task must be done. Some object-oriented languages allow the programmers to express queries explicitly in the code, which are optimized using the query optimization techniques from the database domain. in this regard, Java Query Language has been developed that allows object querying and performs the query optimization at run-time. Therefore, only one problem is how to reduce the task of query optimization at run-time as much as possible within the Java Query Language system. in …

Temporal Scales For Transport Patterns In The Gulf Of Finland, Bert Viikmae, Tarmo Soomere, Mikk Viidebaum, Mihhail Berezovski Jan 2010

Temporal Scales For Transport Patterns In The Gulf Of Finland, Bert Viikmae, Tarmo Soomere, Mikk Viidebaum, Mihhail Berezovski

Publications

The basic time scales for current-induced net transport of surface water and associated time scales of reaching the nearshore in the Gulf of Finland, the Baltic Sea, are analysed based on Lagrangian trajectories of water particles reconstructed from three-dimensional velocity fields by the Rossby Centre circulation model for 1987–1991. The number of particles reaching the nearshore exhibits substantial temporal variability whereas the rate of leaving the gulf is almost steady. It is recommended to use an about 3 grid cells wide nearshore area as a substitute to the coastal zone and about 10–15 day long trajectories for calculations of the …

Neuroscience And The Free Exercise Of Religion, Steven Goldberg Jan 2010

Neuroscience And The Free Exercise Of Religion, Steven Goldberg

Georgetown Law Faculty Publications and Other Works

Recent developments in neuroscience that purport to reduce religious experience to specific parts of the brain will not diminish the fundamental cultural or legal standing of religion. William James debunked this possibility in The Varieties of Religious Experience (1902) when he noted that “the organic causation of a religious state of mind” no more refutes religion than the argument that scientific theories are so caused refutes science. But there will be incremental legal change in areas like civil commitment where judges must sometimes distinguish between mental disorder and religious belief. The paradox is that the ecstatic religious experience of unorthodox …

Closing The Legislative Experience Gap: How A Legislative Law Clerk Program Will Benefit The Legal Profession And Congress, Dakota S. Rudesill Jan 2010

Closing The Legislative Experience Gap: How A Legislative Law Clerk Program Will Benefit The Legal Profession And Congress, Dakota S. Rudesill

Georgetown Law Faculty Publications and Other Works

Most federal law today is statutory or rooted in statutes, which are created through a complicated process best understood through work experience inside legislatures. This article demonstrates that America’s most influential lawyers are not getting it. My new empirical analysis of the work experience of the top 500 lawyers nationwide as ranked by Lawdragon.com finds that work experience in legislative bodies is dramatically less common among the profession’s leaders than is formative work experience in courts, government executive agencies, private practice, and academe. This article continues the empirical study of the professional experience of the legal profession’s elite published in …

Escaping The Extinction Vortex: Identifying Factors Affecting Population Performance And Recovery In Endangered Sierra Nevada Bighorn Sheep, Heather Elizabeth Johnson Jan 2010

Escaping The Extinction Vortex: Identifying Factors Affecting Population Performance And Recovery In Endangered Sierra Nevada Bighorn Sheep, Heather Elizabeth Johnson

Graduate Student Theses, Dissertations, & Professional Papers

An extinction vortex is one of the greatest threats to endangered species; when demographic, environmental, and genetic stochasticity interact with each other and with deterministic factors, such as habitat quality, to reinforce the demise of a small population. To successfully escape an extinction vortex and enable species recovery, all processes that affect endangered populations should be comprehensively assessed and incorporated into conservation plans. For my dissertation, I worked in conjunction with California Department of Fish and Game to develop a comprehensive research program to guide recovery efforts for federally endangered Sierra Nevada bighorn sheep, the rarest subspecies of mountain sheep …

A Case Study In Quantitative Analysis Of Cyber-Physical Systems: Reliability Of The Smart Grid, Ayman Z. Faza

Doctoral Dissertations

"A cyber-physical system is the integration of a physical infrastructure with a cyber infrastructure, which provides control over its physical counterpart. The goal is to improve certain aspects of the physical infrastructure, such as its reliability. The Smart Grid, in which intelligent cyber control is added to improve the operation of the traditional power grid, is a prime example of a cyber-physical system. Quantitative models are needed in order to better understand the benefits and risks of adding intelligence to physical systems. To this end, we have developed an integrated cyber-physical reliability model, with a focus on the Smart Grid …

Feasibility Of Brief Hospital-Based Interventions For Postpartum Depression : Effects On Depressive Symptoms, Perceived Support, & Treatment Utilization, Sabra N. Abboud Jan 2010

Feasibility Of Brief Hospital-Based Interventions For Postpartum Depression : Effects On Depressive Symptoms, Perceived Support, & Treatment Utilization, Sabra N. Abboud

PCOM Psychology Dissertations

It is estimated that 10-20% of childbearing women develop postpartum depression (PPD), affecting up to 400,000 women in the United States each year. As many an 82% of women diagnosed with PPD decline recommended treatment, primarily due to a lack of knowledge about PPD, to societal stigma and to practical barriers. The objective of this study is to evaluate the feasibility of conducting a large-scale study examining the impact of screening measures and a supportive approach immediately postpartum on utilization of recommended care, levels of depression and perceived social support. Women were randomly assigned (N=40) on a maternity unit to …

Rooted: A New Generation Of Farmers And Ranchers In Montana, Beth Jeannette Gibson Jan 2010

Rooted: A New Generation Of Farmers And Ranchers In Montana, Beth Jeannette Gibson

Graduate Student Theses, Dissertations, & Professional Papers

Rooted tells the stories of a new generation of farmers and ranchers in Montana through still photography and written profiles; the project is the result of 13 site visits and interviews. I define “new farmer” as a person operating their own agricultural business for 10 years or fewer, though this definition gets blurred and complicated when referring to people who return to their family’s farm or ranch. Admittedly, this project features only a few of the beginning farmers and ranchers in Montana. My intention is not to provide an exhaustive study of the next generation of farmers and ranchers in …

A Higher-Order Spectro-Temporal Integration Model For Predicting Signal Audibility, Qing Yang, John G. Harris Jan 2010

A Higher-Order Spectro-Temporal Integration Model For Predicting Signal Audibility, Qing Yang, John G. Harris

Electrical and Computer Engineering Faculty Research & Creative Works

A higher-order model to determine audibility of audio signals is presented. Previous models have been energy based (second order) and adequate only for stationary, narrow-band signals. Music, speech and other audio signals are nonstationary and wideband so traditional energy models poorly predict the audibility of these sounds. The predictions from the higher-order model are compared to actual subjective listening tests to show that the higher order, wide-band technique outperforms previous models. ©2010 IEEE.

Limit On Continuous Neutrino Emission From Neutron Stars, Itzhak Goldman, Shmuel Nussinov Jan 2010

Limit On Continuous Neutrino Emission From Neutron Stars, Itzhak Goldman, Shmuel Nussinov

Mathematics, Physics, and Computer Science Faculty Articles and Research

The timing data of the binary pulsar PSR1913+16, are used to establish an upper limit on the rate of continuous neutrino emission from neutron stars. Neutrino emission from each of the neutron stars of the binary system, increases the star binding energy and thus translates to a decrease in their masses. This in turn implies an increase with time of the binary period. Using the pulsar data we obtain an upper limit on the allowed rate of mass reduction: vertical bar M vertical bar < 1.1 x 10(-12) yr(-1) M, where M is the total mass of the binary. This constrains exotic nuclear equations of state that predict continuous neutrino emissions. The limit applies also to other channels of energy loss, e. g. axion emission. Continued timing measurements of additional binary pulsars, should yield a stronger limit in the future.

Effectiveness Of Deer Repellents In Connecticut, Jeffrey S. Ward, Scott C. Williams Jan 2010

Effectiveness Of Deer Repellents In Connecticut, Jeffrey S. Ward, Scott C. Williams

Human–Wildlife Interactions

Browsing by overabundant herds of white-tailed deer (Odocoileus virginianus) can cause significant economic damage to agricultural crops and landscape plantings. In many instances, for both commercial growers and homeowners, commercially available repellents may be an appealing alternative to physical exclusion and lethal control of animals. We tested 10 different commercially-available repellents (Chew-Not®, Deer Off®, Deer-Away® Big Game Repellent, Plantskydd®, Bobbex®, Liquid Fence®, Deer Solution®, Hinder®, Repellex® systemic tablets, and coyote urine) on yews (Taxus cuspidata Densiformis) at 2 different locations in Connecticut. The study included both positive (fence) and negative (no treatment) controls. We planted yews in …

Driver Knowledge, Beliefs, And Attitudes About Deer–Vehicle Collisions In Southern Michigan, Alix Marcoux, Shawn J. Riley Jan 2010

Driver Knowledge, Beliefs, And Attitudes About Deer–Vehicle Collisions In Southern Michigan, Alix Marcoux, Shawn J. Riley

Human–Wildlife Interactions

Deer–vehicle collisions (DVCs) are one of the most frequent and costly human– wildlife conflict throughout the range of white-tailed deer (Odocoileus virginianus). We conducted a self-administered, mail-back survey of Michigan drivers to determine: (1) driver attitudes and knowledge about DVCs; (2) reporting rates of DVCs; and (3) effects of being in a DVC on attitudes toward desired deer population levels. From a sample of 3,600 randomly selected licensed drivers >18 years of age in southeast Michigan, we obtained 1,653 completed questionnaires (48% response rate). Although 18% of respondents reported experiencing >1 DVC within 5 years of the survey …

European Starling Preferences For Bait Substrates Used In Drc-1339 Applications, H. Jeffrey Homan, George M. Linz, Scott Beckerman, Anthony G. Duffiney, Thomas D. Halstead

Human–Wildlife Interactions

Additional bait substrates for the avicide, DRC-1339 Concentrate (3-chloro-4- methylaniline hydrochloride), could provide USDA/Wildlife Services with more fl exibility when managing nuisance populations of European starlings (Sturnus vulgaris) at livestock facilities. From January 11 to 21, 2008, we conducted 11 2-choice preference tests with 6 bait types at a feedlot in central Kansas. The baits included cracked corn mixed with lard (2 concentrations), 2 forms of distiller’s grain (wet powder and pellets), 2 types of livestock feed (calf-starter pellet and sweet-feed mix), and a custom-produced poultry pellet (carrier pellet) made by USDA specifically for baiting starlings. We evaluated …

An Effective Chemical Deterrent For Invasive Cuban Treefrogs, Steve A. Johnson, Monica E. Mcgarrity, Christina L. Staudhammer Jan 2010

An Effective Chemical Deterrent For Invasive Cuban Treefrogs, Steve A. Johnson, Monica E. Mcgarrity, Christina L. Staudhammer

Human–Wildlife Interactions

Introduced vertebrates have a variety of impacts on ecosystems and economies, and many cause problems for humans. One such problem is the loss of electrical power when invasive animals cause short circuits in power-transmission equipment. Cuban treefrogs (Osteopilus septentrionalis) are known to cause power outages and are a nuisance to humans when they invade homes and defecate on doors and windows. These large, slightly toxic treefrogs were introduced into Florida from the Caribbean. They now occur throughout the peninsula of Florida and are spreading to other states in the Southeast. We used refuge choice experiments to test the …

Metapopulation Dynamics Of Mid-Continent Lesser Snow Geese: Implications For Management, Lise M. Aubry, Robert F. Rockwell, David N. Koons Jan 2010

Metapopulation Dynamics Of Mid-Continent Lesser Snow Geese: Implications For Management, Lise M. Aubry, Robert F. Rockwell, David N. Koons

Human–Wildlife Interactions

The rapid increase in abundance of lesser snow goose (LSG; Chen caerulescens caerulescens) numbers and their devastating effects on arctic and subarctic habitats has inspired much research on the use of population models for defining appropriate management policies. We use the not yet considered metapopulation approach to examine the elasticity of mid-continent LSG population dynamics to changes in underlying vital rates to determine whether management efforts aimed at decreasing burgeoning numbers should be reevaluated. After considering a variety of geographic scenarios in the metapopulation model, we found that changes in survival would still have a larger impact on population …

Bulldozers And Blueberries: Managing Fence Damage By Bare-Nosed Wombats At The Agricultural–Riparian Interface, Philip Borchard, Ian A. Wright

Human–Wildlife Interactions

Fence damage by bare-nosed wombats (Vombatus ursinus) can be a serious problem for farmers wishing to reduce herbivory by other herbivores on valuable crops. We investigated the effectiveness of exclusion fencing to prevent the incursion of unwanted native and feral herbivores and the use of swinging gates designed to allow wombats to pass through the fence without having to damage it. We also examined the temporal response of animals toward exclusion fencing and wombat gates. The 10-month study took place on the interface between natural riparian vegetation and a 22-ha blueberry (Vaccinium corymbosum) orchard in southeastern …

Bullet Fragmentation And Lead Deposition In White-Tailed Deer And Domestic Sheep, Marrett D. Grund, Louis Cornicelli, Leah T. Carlson, Erika A. Butler Jan 2010

Bullet Fragmentation And Lead Deposition In White-Tailed Deer And Domestic Sheep, Marrett D. Grund, Louis Cornicelli, Leah T. Carlson, Erika A. Butler

Human–Wildlife Interactions

In February 2008, a private physician in North Dakota radiographed hunterharvested venison and found that 60 of 100 packages contained metal fragments. This discovery had implications for public-funded venison donation programs, and it prompted several Midwest states to examine their programs. Approximately 500,000 deer hunters harvest >200,000 deer annually in Minnesota, and the state has a donation program similar to North Dakota’s program. Therefore, we analyzed fragmentation patterns and lead deposition in carcasses of 8 white-tailed deer (Odocoileus virginianus) and 72 domestic sheep (Ovis aries). We fired 5 different bullet types from centerfire rifles, and we …
