    Government Programs Can Improve Local Labor Markets: Evidence From State Enterprise Zones, Federal Empowerment Zones And Federal Enterprise Communities1

    Federal and state governments spend well over a billion dollars a year on programs that encourage employment development in disadvantaged labor markets through the use of subsidies and tax credits. In this paper author uses an estimation approach that is valid under relatively weak assumptions to measure the impact of...

    Fitting Linear and Nonlinear Growth Curve Models Using PROC NLMIXED

    Longitudinal data, or data that are repeated measurements on various subjects across time, are commonplace in everyday life. Multi-level mixed models are often used for analyzing longitudinal data and drawing meaningful inferences about them. This paper discusses two common mixed models, the linear growth model and the logistic growth model,...

    Faster Network Design with Scenario Prefiltering

    The whole notion of writing this paper is to introduce and evaluate the concept of relevant scenario pre-filtering. A network is designed considering all possible configurations including network topologies, bandwidths, traffic, and policies. This paper discusses all analytical techniques that determine behavior of the network with bulk and short term...

    Minimizing Data Center Cooling and Server Power Costs

    Data centers have been often accused of high power consumption used for running of information technology equipment and for air conditioning. The paper focuses on total data center power optimization through a mathematical problem formulation along with an efficient algorithm to bring down the total data center power cost to...

    On The Effectiveness Of The California Enterprise Zone Program

    Recent empirical evidence (Neumark and Kolko, 2008) finds that the California Enterprise Zone (EZ) program does not increase employment. The result is in stark contrast to other empirical work (Ham, et al, 2009), which examines economic impact beyond simple employment statistics, showing that EZs increase employment and wages, and decrease...

    Dynamic Data Compression in Multi-Hop Wireless Networks

    Data compression can save energy and increase network capacity in wireless sensor networks. However, the decision of whether and when to compress data can depend upon platform hardware, topology, wireless channel conditions, and application data rates. Using Lyapunov optimization theory, it designs an algorithm called seec that makes joint compression...

    Durability of Wireless Networks of Battery-Powered Devices

    Given the criticality of energy awareness in wireless networks, it has become essential to devise an improved definition of the network lifetime at the system design stage. The new definition must capture the life profile of the network while accounting for its functionality and specific design parameters. This paper presents...

    A Choice Model With Spatial Correlation In Preference And Response Applied To Promotional Planning In The Auto Industry

    Previous research in marketing has highlighted the role of structural state dependence in consumer choice behavior by showing how consumer's current choices are affected by past purchases. The paper proposes a Bayesian autoregressive spatial choice model in which consumers' product preferences and marketing mix responsiveness co-vary depending upon their relative...

    Dilution And Enhancement Of Celebrity Brands Through Sequential Movie Releases

    This paper examines the effects of sequential movie releases on the dilution and enhancement of celebrity brands. The authors use favorability ratings collected over a 12-year period (1993 to 2005) to capture movement in the brand equity of a panel of actors/actress. A dynamic panel data model is used to...

    Cache Replacement Techniques for Streaming Media In Wireless Home Networks

    Wireless home networks are widely deployed due to their low cost, ease of installation, and plug-and-play capabilities with consumer electronic devices. Participating devices may cache continuous media (Audio and Video Clips) in order to reduce the demand for outside-the-home network resources and improve the average delay incurred from when a...

    Comparison and Evaluation of the T-Lohi MAC for Underwater Acoustic Sensor Networks

    This paper introduces T-Lohi, a new class of distributed and energy-efficient Media-Access Protocols (MAC) for Underwater Acoustic Sensor Networks (UWSN). MAC design for UWSN faces significant challenges. For example, acoustic communication suffers from latencies five orders-of-magnitude larger than radio communication, so a naive CSMA MAC would require very long listen...

    An Examination of the Impact of Rent Control on Mobile Home Prices in California

    This study examines the impact of rent control of mobile home parks in seven counties of California between 1983 and 2003. Sales of mobile homes on rent-controlled pads are hypothesized to sell at prices higher than identical models sold in mobile home parks without rent control. The statistical tests corroborated...
