A Quay Crane System That Self-Recovers From Random Shocks, Yun Fong Lim, Yan Zhang, Chen Wang

Research Collection Lee Kong Chian School Of Business

The main challenge for a container terminal is to maximize its throughput using limited resources subject to various operational constraints under uncertainty. Traditional methods try to achieve this through an optimized plan by solving a quay crane scheduling problem; but the plan may become obsolete or infeasible after shocks (changes in the system due to uncertainty). To respond to shocks these methods require frequent re-planning, which increases the operations cost. We propose a new method to counter this. Instead of creating plans, we develop an operating protocol to respond to shocks without re-planning. Under this protocol, each quay crane along …

Industry Interdependencies And Cross-Industry Return Predictability, David E. Rapach, Jack Strauss, Jun Tu, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

We use the adaptive LASSO from the statistical learning literature to identify economically connected industries in a general framework that accommodates complex industry interdependencies. Our results show that lagged returns of interdependent industries are significant predictors of individual industry returns, consistent with gradual information diffusion across industries. Using network analysis, we find that industries with the most extensive predictive power are key central nodes in the production network of the U.S. economy. Further linking cross-return predictability to the real economy, lagged employment growth for the interdependent industries predicts individual industry employment growth. We also compute out-of-sample industry return forecasts based …

Research Collection Lee Kong Chian School Of Business

We are currently witnessing a major transition from the old type of industrialsociety with its traditional dominance of manufacturing work and old industrialclasses to an information and knowledge-based society (Albrow and King 1981;Drucker 1994; Stehr 1994; Hannerz 1996; Baber 1998; Evers 2000, 2000a,b,c)which is believed to have the following characteristics:· Its members have attained a higher average standard of education incomparison to other societies and a growing proportion of its labour force areemployed as knowledge workers. In other words, there is a significantreduction in the number of people working in operational roles, whileemployment in professional, knowledge-based roles has risen.· Its …

Strategy And Grand Strategy: What Students And Practitioners Need To Know, Tami Davis Biddle Dr.

Books, Monographs & Collaborative Studies

In this monograph, Dr. Tami Davis Biddle examines why it is so difficult to devise, implement, and sustain sound strategies and grand strategies. Her analysis begins with an examination of the meaning of the term “strategy” and a history of the ways that political actors have sought to employ strategies and grand strategies to achieve their desired political aims. She examines the reasons why the logic undergirding strategy is often lacking and why challenges of implementation (including bureaucratic politics, unforeseen events, civil-military tensions, and domestic pressures) complicate and undermine desired outcomes. This clear-headed critique, built on a broad base of …

Identities And Motives Of Naturalist Development Program Attendees And Their Relation To Professional Careers, Jennifer A. Mraz

Dissertations

In recent years, there has been much concern over the decline of biologists who actually identify themselves to be naturalists, which negatively impacts the field of conservation and the study of biology as a whole. This could result in a decrease in individuals who participate in naturalist-like activities, such as informal environmental education and environmental volunteerism. The purpose of my study was to determine what discourse identities were held by naturalist development program participants, how these discourse identities related to their volunteer motives in environmental settings, and how discourse identity related to professional careers. I defined identity through the lens …

Wiyot, Wiki And Batawat People, Susie Van Kirk

Susie Van Kirk Papers

In June 1900, Stewart Culin (1858-1929), self-educated anthropologist/ethnographer, traveled to northwestern California on a colleting trip. He was then Director of the University of Pennsylvania’s Museum of Archaeology and Paleontology, and the purpose of his trip to was to secure “a number of Indian curios and relics,” which he did, spending about $150 in Hoopa. He also secured curios from the Mad River Indians near Blue Lake (Blue Lake Advocate 23 June 1900).

Just what Culin collected is unclear, other than the baskets, probably all of which were either Hupa or Yurok, and possibly some Karuk. The tribal heritage of …

Control Of Mesoscopic Transport By Modifying Transmission Channels In Opaque Media, Raktim Sarma, Alexey Yamilov, Seng Fatt Liew, Mikhael Guy, Hui Cao

Physics Faculty Research & Creative Works

While controlling particle diffusion in a confined geometry is a popular approach taken by both natural and artificial systems, it has not been widely adopted for controlling light transport in random media, where wave interference effects play a critical role. The transmission eigenchannels determine not only light propagation through the disordered system but also the energy concentrated inside. Here, we propose and demonstrate an effective approach to modify these channels, whose structures are considered to be universal in conventional diffusive waveguides. By adjusting the waveguide geometry, we are able to alter the spatial profiles of the transmission eigenchannels significantly and …

Degradation Of Organic Pollutants And Microorganisms From Wastewater Using Different Dielectric Barrier Discharge Configurations—A Critical Review, Emile S.Massima Mouele, Jimoh O. Tijani, Ojo O. Fatoba, Leslie F. Petrik

Mining Engineering Faculty Research & Creative Works

The growing global drinking water crisis requires the development of novel advanced, sustainable, and cost-effective water treatment technologies to supplement the existing conventional methods. One such technology is advanced oxidation based on dielectric barrier discharge (DBD). DBD such as single and double planar and single and double cylindrical dielectric barrier configurations have been utilized for efficient degradation of recalcitrant organic pollutants. The overall performance of the different DBD system varies and depends on several factors. Therefore, this review was compiled to give an overview of different DBD configurations vis-a-viz their applications and the in-situ mechanism of generation of free reactive …

Revising International Law: A Liberal Account Of Natural Resources, Fernando R. Tesón

San Diego Law Review

In this Article, I defend the view that natural resources originally belong to individuals who have legitimately established private property claims over them. Natural resources do not belong to a collective entity such as the people or the state. My argument is simple. Relying on the Lockean contractarian tradition, I argue that individuals must delegate any resource controlled by the state. This is because all powers of the state are, morally, delegated powers. A group’s claims over natural resources is entirely derivative of the original claims of its members. Only individuals can originally appropriate natural resources; only they have the …

Linear Programming-Based Estimators In Nonnegative Autoregression, Daniel P. A. Preve

Research Collection School Of Economics

This note studies robust estimation of the autoregressive (AR) parameter in a nonlinear, nonnegative AR model. It is shown that a linear programming estimator (LPE), considered by Nielsen and Shephard (2003) among others, remains consistent under severe model misspecification. Consequently, the LPE can be used to seek sources of misspecification and to isolate certain trend, seasonal or cyclical components. Simple and quite general conditions under which the LPE is strongly consistent in the presence of heavy-tailed, serially correlated, heteroskedastic disturbances are given, and a brief review of the literature on LP-based estimators in nonnegative autoregression is presented. Finite-sample properties of …

The Impact Of Agglomeration Economies On Hospital Input Prices, Andrew Friedson, Jing Li

Research Collection School Of Economics

This paper examines the extent to which agglomeration of the hospital service industry enhances the productivity of producing health care. Specifically, we use a large set of private insurance claims from the FAIR Health database to show that an increasing spatial concentration of hospital services results in a decreased cost of obtaining intermediate medical services. We explicitly test whether the reduced cost at concentrated locations arises from the ability to share intermediate service providers. The identification relies on state variation in medical lab technician licensure requirements, which influence the cost of intermediate services only through the cost of running a …

Competition And Gains From Trade: A Quantitative Analysis Of China Between 1995 And 2004, Wen-Tai Hsu, Yi Lu, Guiying Laura Wu

Research Collection School Of Economics

This paper provides a quantitative analysis of gains from trade for China over the period of 1995-2004, which was when China's openness drastically improved. We decompose gains from trade in two ways. First, we disentangle pro-competitive effects from a traditional Ricardian effect. Second, we separate the effect due to tariff reductions from that due to reductions in non-tariff trade costs. Our quantitative analysis shows that the pro-competitive effects account for 25.4% of the total welfare gains from trade, whereas the allocative efficiency alone accounts for 22.3%. We also find that tariff reductions account for about 31.6% of reductions of overall …

Trade Integration, Income Divergence, And Global Imbalances, Haiping Zhang

Research Collection School Of Economics

We embed financial frictions and sector-specific minimum investment requirements (MIR) in a two-factor, two-sector, overlapping-generation model and showthat whether trade integration leads to convergence of the income levels among member states depends on their level of financial development. It helps reconcilethe mixed empirical evidence on trade integration and income dynamics in differentgroups of countries from the institutional perspective. In the recent decades, trade globalization has allowed developed countries to specialize towards the high-MIR, high-return production stages and tasks through international fragmentation of production and global sourcing. In our model, the “sectors” can be interpreted broadly as production stages and tasks. …

Unified M-Estimation Of Fixed-Effects Spatial Dynamic Models With Short Panels, Zhenlin Yang

Research Collection School Of Economics

It is well known that quasi maximum likelihood (QML) estimation of dynamic panel data (DPD) models with short panels depends on the assumptions on the initial values, and a wrong treatment of them will result in inconsistency and serious bias. The same issues apply to spatial DPD (SDPD) models with short panels. In this paper, a unified Mestimation method is proposed for estimating the fixed-effects SDPD models containing three major types of spatial effects, namely spatial lag, spatial error and space-time lag. The method is free from the specification of the distribution of the initial observations and robust against nonnormality …

Institutional Complementarity Across Countries In Bilateral Fdi Flows: Theory And Evidence, Pao-Li Chang

Research Collection School Of Economics

This paper builds a theory to characterize the comparative advantage of MNEs based in countries of different institutional qualities. It is shown that MNEs headquartered in countries of poorer state institutions will invest more in `informal institutions; and choose to undertake FDI in countries of weaker institutions. At the aggregate, MNEs on average generate more net profits in countries of weaker institutions, the poorer the institutional environment at home. I conduct an extensive test of the theory using bilateral FDI volume for 219 economies in year 2001-2010. The results indicate a statistically significant and robust institutional complementarity effect in bilateral …

New Methodology For Constructing Real Estate Price Indices Applied To The Singapore Residential Market, Liang Jiang, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

This paper develops a new methodology for constructing a real estate price index that utilizes all transaction price information, encompassing both single-sales and repeat-sales. The method is less susceptible to specification error than standard hedonic methods and is not subject to the sample selection bias involved in indexes that rely only on repeat sales. The methodology employs a model design that uses a sale pairing process based on the individual building level, rather than the individual house level as is used in the repeat-sales method. The approach extends ideas from repeat-sales methodology in a way that accommodates much wider datasets. …

Adaptive Nonparametric Regression With Conditional Heteroskedasticity, Sainan Jin, Liangjun Su, Zhijie Xiao

Research Collection School Of Economics

In this paper, we study adaptive nonparametric regression estimation in the presence of conditional heteroskedastic error terms. We demonstrate that both the conditional mean and conditional variance functions in a nonparametric regression model can be estimated adaptively based on the local profile likelihood principle. Both the one-step Newton-Raphson estimator and the local profile likelihood estimator are investigated. We show that the proposed estimators are asymptotically equivalent to the infeasible local likelihood estimators [e.g., Aerts and Claeskens (1997) Journal of the American Statistical Association 92, 1536-1545], which require knowledge of the error distribution. Simulation evidence suggests that when the distribution of …

Csi Agent On A Mission Game App, Ju Mae Rosie Ching

Research Collection School Of Economics

CSI is a one-of-a-kind and first-ever iPad gaming app released early August, with the flash game at http://www.rosieching.com/csi. My primary objective was to realize my dreamed-up “MISSION STATISTICS” theme for students to apply their skills in hypothesis tests and linear regression. Another is the incorporation of their CSI results into an “enrichment 5%” of their grades. The harder an agent works, the higher his score, the sweeter the fruit of the labour which students always show massive enthusiasm for. It is also critical that students review their real-time progress, and I have ensured that in every step of each country’s …

On The Unreliability Of Bug Severity Data, Yuan Tian, Nasir Ali, David Lo, Ahmed E. Hassan

Research Collection School Of Computing and Information Systems

Severity levels, e.g., critical and minor, of bugs are often used to prioritize development efforts. Prior research efforts have proposed approaches to automatically assign the severity label to a bug report. All prior efforts verify the accuracy of their approaches using human-assigned bug reports data that is stored in software repositories. However, all prior efforts assume that such human-assigned data is reliable. Hence a perfect automated approach should be able to assign the same severity label as in the repository – achieving a 100% accuracy. Looking at duplicate bug reports (i.e., reports referring to the same problem) from three open-source …

A Cooperative Coevolution Framework For Parallel Learning To Rank, Shuaiqiang Wang, Yun Wu, Byron J. Gao, Ke Wang, Hady W. Lauw, Jun Ma

Research Collection School Of Computing and Information Systems

We propose CCRank, the first parallel framework for learning to rank based on evolutionary algorithms (EA), aiming to significantly improve learning efficiency while maintaining accuracy. CCRank is based on cooperative coevolution (CC), a divide-and-conquer framework that has demonstrated high promise in function optimization for problems with large search space and complex structures. Moreover, CC naturally allows parallelization of sub-solutions to the decomposed sub-problems, which can substantially boost learning efficiency. With CCRank, we investigate parallel CC in the context of learning to rank. We implement CCRank with three EA-based learning to rank algorithms for demonstration. Extensive experiments on benchmark datasets in …

Safety Analysis Of Freeway Segments With Unobserved Heterogeneity And Second Order Spatial Effects, Eneliko Mujuni Mulokozi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Safety analysis of freeway networks entails the quantification of crash frequency influencing factors which include roadway and traffic characteristics, environmental factors as well as human factors. This quantification can be used to detect locations with large impacts on the occurrence of crashes which in turn assist engineers and planners to improve safety levels of the network. Roadway characteristics are comprised of the physical elements of the road geometry such as section length, median and right shoulders, speed-exchange lanes, the number of main facility as well as geometry of the entrance from and exit to the main freeway facility. Traffic characteristics …
