Non-Parametric Methods For Soil Moisture Retrieval From Satellite Remote Sensing Data, Tarendra Lakhankar, Hosni Ghedira, Marouane Temimi, Manajit Sengupta, Reza Khanbilvardi, Reginald Blake Mar 2009

Non-Parametric Methods For Soil Moisture Retrieval From Satellite Remote Sensing Data, Tarendra Lakhankar, Hosni Ghedira, Marouane Temimi, Manajit Sengupta, Reza Khanbilvardi, Reginald Blake

Publications and Research

Satellite remote sensing observations have the potential for efficient and reliable mapping of spatial soil moisture distributions. However, soil moisture retrievals from active microwave remote sensing data are typically complex due to inherent difficulty in characterizing interactions among land surface parameters that contribute to the retrieval process. Therefore, adequate physical mathematical descriptions of microwave backscatter interaction with parameters such as land cover, vegetation density, and soil characteristics are not readily available. In such condition, non-parametric models could be used as possible alternative for better understanding the impact of variables in the retrieval process and relating it in the absence of …

Ethics And Vulnerability In Street Prostitution; An Argument In Favour Of Managed Zones, Anna Carline Mar 2009

Ethics And Vulnerability In Street Prostitution; An Argument In Favour Of Managed Zones, Anna Carline

SOLON Law, Crime and History (previously SOLON Crimes and Misdemeanours: Deviance and the Law in Historical Perspective)

This article draws upon the work of Judith Butler, in particular her approach to ethics and the concepts of vulnerability and 'liveable lives,' in order to provide a critical analysis of reform proposals contained in the Criminal Justice and Immigration Bill (now Act 2008) in relation to street prostitution. The article will argue that the proposals presented in the Bill problematically use the vulnerability of street sex workers in order to promote a moralistic agenda. In contrast it will be argued that managed zones, as proposed by Liverpool City Council, provide a potentially more ethical approach to the issue of …

Nonknowledge: The Bibliographical Organization Of Ignorance, Stupidity, Error, And Unreason: Part One, Jay H. Bernstein Mar 2009

Nonknowledge: The Bibliographical Organization Of Ignorance, Stupidity, Error, And Unreason: Part One, Jay H. Bernstein

Publications and Research

Starting with the Data-Information-Knowledge-Wisdom paradigm in information science it is possible to derive a model of the opposite of knowledge having hierarchical qualities. A range of counterpoints to concepts in the knowledge hierarchy can be identified and ascribed the overall term “nonknowledge.” This model creates a conceptual framework for understanding the connections between topics such as error, ignorance, stupidity, folly, popular misconceptions, and unreason by locating them as levels or phases of nonknowledge. The concept of nonknowledge links heretofore disconnected discourses on these individual topics by philosophers, psychologists, historians, sociologists, satirists, and others. Subject headings provide access to the categories …

Initial Attraction To Organizations: The Influence Of Trait Inferences, Jerel E. Slaughter, Gary J. Greguras

Research Collection Lee Kong Chian School Of Business

Organization personality perceptions have been defined as the set of personality characteristics associated with organizations. Previous research supports five distinct factors of organization personality perceptions: Boy Scout, Innovativeness, Dominance, Thrift, and Style. The purpose of this research was to understand how individuals' initial attraction to firms is influenced by their perceptions of the degree to which firms display these traits. Results of the present investigation indicated that organization personality perceptions accounted for significant variance in initial organizational attraction, after controlling for perceptions of the degree to which the jobs at the organizations offer traditional attributes. In addition, several self-rated Big …

Intergenerational Earnings Mobility In Singapore And The United States, Irene Y. H. Ng, Xiaoyi Shen, Kong Weng Ho Mar 2009

Intergenerational Earnings Mobility In Singapore And The United States, Irene Y. H. Ng, Xiaoyi Shen, Kong Weng Ho

Research Collection School Of Economics

This study compared intergenerational earnings mobility in Singapore and the United States by replicating the sample criteria in the Singapore National Youth Survey on the U.S. Panel Study of Income Dynamics. The mean estimated earnings elasticities are almost identical: 0.26 in Singapore and 0.28 in the United States. Transformed to 0.44 and 0.47 respectively to reflect permanent status, mobility in the two countries is moderately low compared internationally. The finding of similar mobility is not surprising given that the two countries have similar economic realities, welfare systems, education regimes, and labor structures. Policy makers face the daunting challenge of overcoming …

Optics And Remote Sensing Of Bahamian Carbonate Sediment Whitings And Potential Relationship To Wind-Driven Langmuir Circulation, H. M. Dierssen, Richard C. Zimmerman, David J. Burdige

OES Faculty Publications

Regions of milky white seas or "whitings" periodically occur to the west of Andros Island along the Great Bahama Bank where the bottom sediment consists of fine-grained aragonite mud. We present measurements of inherent optical properties within a sediment whiting patch and discuss the potential for monitoring the frequency, extent, and quantity of suspended matter from ocean colour satellite imagery. Sea spectral reflectance measured in situ and remotely from space revealed highly reflective waters elevated across the visible spectrum (i.e., "whitened") with a peak at 490 nm. Particulate backscattering was an order of magnitude higher than that measured at other …

Acute Stress Modulates Risk Taking In Financial Decision Making, Anthony J. Porcelli, Mauricio R. Delgado Mar 2009

Acute Stress Modulates Risk Taking In Financial Decision Making, Anthony J. Porcelli, Mauricio R. Delgado

Psychology Faculty Research and Publications

People’s decisions are often susceptible to various demands exerted by the environment, leading to stressful conditions. Although a goal for researchers is to elucidate stress-coping mechanisms to facilitate decision-making processes, it is important to first understand the interaction between the state created by a stressful environment and how decisions are performed in such environments. The objective of this experiment was to probe the impact of exposure to acute stress on financial decision making and examine the particular influence of stress on decisions with a positive or negative valence. Participants’ choices exhibited a stronger reflection effect when participants were under stress …

Synthesis And Evaluation Of Lanthanide Ion Dota-Tetraamide Complexes Bearing Peripheral Hydroxyl Groups, Azhar Pasha, Mai Lin, Gyula Tircso, Cynthia L. Rostollan, Mark Woods, Garry Kiefer, A. Dean Sherry, Xiankai Sun

Chemistry Faculty Publications and Presentations

The use of lanthanide-based contrast agents for magnetic resonance imaging has become an integral component of this important diagnostic modality. These inert chelates typically possess high thermodynamic stability constants that serve as a predictor for in vivo stability and low toxicity. Recently, a new class of contrast agents was reported having a significantly lower degree of thermodynamic stability while exhibiting biodistribution profiles indicative of high stability under biological conditions. These observations are suggestive that the nature of contrast agent stability is also dependent upon the kinetics of complex dissociation, a feature of potential importance when contemplating the design of new …

The Effectiveness Of The Organization In The Philosophy Of The Most Prominent Theoretician Administrative Thought, Saad Ali Al-Anzi, Yarub Adnan Hussein Alsiede, Ahmed Nizar Al-Nouri

Journal of Economics and Administrative Sciences

This paper discuses the mindset contribution of the organization Science in organizational effectiveness (OE), and the most valuable thoughts they introduced in this subject, starting from the pre- classical era, through classical era to present time. This paper has identified the main contribution in OE. The concept of OE didn’t arise until what had been introduced by Chester Barnard, although Max Weber mentioned this concept in his bureaucratic theory, but he didn’t explain it as Barnard does. After that no clear focus was pointed to this subject until Peter Drucker did so, which considered as the main participant in OE …

Multiracial Identity Integration: Perceptions Of Conflict And Distance Among Multiracial Individuals, Chi-Ying Cheng, Fiona Lee Mar 2009

Multiracial Identity Integration: Perceptions Of Conflict And Distance Among Multiracial Individuals, Chi-Ying Cheng, Fiona Lee

Research Collection School of Social Sciences

This article examines how multiracial individuals negotiate their different and sometimes conflicting racial identities. Drawing from previous work on bicultural identity integration (see Benet-Martinez and Haritatos, 2005), we proposed a new construct, multiracial identity integration (MII), to measure individual differences in perceptions of compatibility between multiple racial identities. We found that MII is composed of two independent subscales: that describes whether different racial identities are perceived as disparate, and that describes whether different racial identities are perceived as in conflict. We also found that recalling positive multiracial experiences increased MII, while recalling negative multiracial experiences decreased MII. These findings have …

Birth Weight, Math And Reading Achievement Growth: A Multilevel Between-Sibling, Between-Families Approach, Bridget J. Goosby, Jacob Cheadle Mar 2009

Birth Weight, Math And Reading Achievement Growth: A Multilevel Between-Sibling, Between-Families Approach, Bridget J. Goosby, Jacob Cheadle

Department of Sociology: Faculty Publications

We used multilevel covariance structure analysis to study the relationship between birth weight, family context and youth math and reading comprehension growth from approximately ages 5 through 14 within and between families. Using data from the National Longitudinal Survey of Youth Child Sample, we examined the relationship between birth weight and subsequent academic achievement growth disparities, distinguishing between birth weight and other contextual social confounders. We found that smaller birth weight is associated with lower math and reading scores at age 5. Additional findings indicated that the home environment has important developmental consequences from early childhood and into adolescence. Overall, …

Network Security Using Self Organized Multi-Agent Swarms, Eric M. Holloway, Gary B. Lamont, Gilbert L. Peterson Mar 2009

Network Security Using Self Organized Multi-Agent Swarms, Eric M. Holloway, Gary B. Lamont, Gilbert L. Peterson

Faculty Publications

Computer network cyber-security is a very serious concern in many commercial, industrial, and military environments. This paper proposes a new computer network security approach defined by self organized agent swarms (SOMAS) which provides a novel computer network security management framework based upon desired overall system behaviors. The SOMAS structure evolves based upon the partially observable Markov decision process (POMDP) formal model and the more complex interactive-POMDP and decentralized-POMDP models. Example swarm specific and network based behaviors are formalized and simulated. This paper illustrates through various statistical testing techniques, the significance of this proposed SOMAS architecture.

Past With Present: A Design Process, Spencer Knape Biegler

Theses

The design process detailed in this thesis addresses how a designer brings a design that is both relevant but dated into the present. Four stages make up the design process: investigation, scattered design, design réseau, and focused design, and the process covers the choice of artifact, historical and cultural research, and the conclusions derived from research. The chandelier acts as artifact in this design process iteration. The goal of the thesis project is a process that stresses both innovation as well as the cultural and symbolic importance of older designs; the outcome of this design iteration is honed chandelier concepts …

Positional Information Generated By Spatially Distributed Signaling Cascades., Javier Muñoz-García, Zoltan Neufeld, Boris N Kholodenko Mar 2009

Positional Information Generated By Spatially Distributed Signaling Cascades., Javier Muñoz-García, Zoltan Neufeld, Boris N Kholodenko

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The temporal and stationary behavior of protein modification cascades has been extensively studied, yet little is known about the spatial aspects of signal propagation. We have previously shown that the spatial separation of opposing enzymes, such as a kinase and a phosphatase, creates signaling activity gradients. Here we show under what conditions signals stall in the space or robustly propagate through spatially distributed signaling cascades. Robust signal propagation results in activity gradients with long plateaus, which abruptly decay at successive spatial locations. We derive an approximate analytical solution that relates the maximal amplitude and propagation length of each activation profile …
