Sub-Femtosecond Correlated Dynamics Explored With Antiprotons, J. Ullrich, A. Dorn, Daniel Fischer, R. Moshammer, B. Najjari, Michael Schulz, A. B. Voitkiv, C. P. Welsch

Physics Faculty Research & Creative Works

Ionizing collisions of antiprotons with atoms or molecules at energies between a few keV up to about one MeV provide a unique tool to explore correlated dynamics of electrons at large perturbations on a time scale between several femtoseconds (1 fs = 10^-15 s) down to some tens of attoseconds (1 as = 10^-18 s). Exploiting and developing many-particle imaging methods - Reaction-Microscopes - integrated into a novel ultra-low energy storage ring (USR) for slow antiprotons will enable to access for the first time fully differential cross sections for single and multiple ionization in such collisions. Moreover, the …

Future Targets And Multiple Equilibria, Ashok S. Guha, Brishti Guha

Research Collection School Of Economics

Multiple Pareto-rankable equilibria may obtain in an overlapping generations model where consumers save to reach a fixed target. Existence and uniqueness conditions are discussed. The model displays excess consumption sensitivity to current income and perfect old-age insurance.

Institutions, Wages, And Inequality: The Case Of Europe And Its Periphery (1500-1899), Davin Chor

Research Collection School Of Economics

This paper explores the long-run relationship between institutions and wage outcomes in Europe and its periphery. I find that cities that exercised stronger institutional protection of private property experienced: (i) higher levels of both skilled and unskilled real wages, as well as (ii) lower levels of inequality as measured by the skilled-unskilled wage ratio. While the first result corroborates existing work on the positive growth effects of better institutions, the second finding is more novel to the literature. Some explanations are proposed for how stronger institutions can cause an increase in the relative supply of skilled workers, thus lowering wage …

Q-Convergence With Interquartile Ranges, Sung Jin Kang, Myoung-Jae Lee

Research Collection School Of Economics

We introduce a new convergence concept ‘Q-convergence’ which defines convergence in national incomes as a shrinking interquartile range (IQR) of the national income distribution. Compared with the other convergence definitions in the literature, Q-convergence has the following advantages. First, IQR, which represents dispersion and inequality of the income distribution, is also closely linked to the two-group clustering with the lower and upper quartiles being the ‘centers’ of the two groups. Second, IQR is equivariant to increasing transformations and thus reconciles better conflicting empirical findings using level or log data. Third, IQR is insensitive to outliers, leading to robust statistical inferences. …

The Optimal Design Of Fallible Organizations: Invariance Of Optimal Decision Criterion And Uniqueness Of Hierarchy And Polyarchy Structures, Winston T. H. Koh

Research Collection School Of Economics

We present a general framework to study the project selection problem in an organization of fallible decision-makers. We show that when the organizational size and the majority rule for project acceptance are optimized simultaneously, the optimal quality of decision-making, as determined by the decision criterion, is invariant, and depends only on the expertise of decision-makers. This result clarifies that the circumstances under which the decision-making quality varies with the organizational structure are situations where the organizational size or majority rule is restricted from reaching the optimal level. Moreover, in contrast to earlier findings in the literature that the hierarchy and …

A New Approach To Robust Inference In Cointegration, Sainan Jin, Peter Phillips, Yixiao Sun

Research Collection School Of Economics

A new approach to robust testing in cointegrated systems is proposed using non-parametric HAC estimators without truncation. While such HAC estimates are inconsistent, they still produce asymptotically pivotal tests and, as in conventional regression settings, can improve testing and inference.

Review Of Theory Of Regular Economies, Zhenlin Yang

Research Collection School Of Economics

This book provides a systematic treatment of the theory of regular economies, one of themost advanced topics in modern general equilibrium theory, emphasizing on the basiceconomic ideas, mathematical tools and important economic applications. By introducingthe necessary mathematical tools, in particular the Differential Topology, graduallywhen needed, Professor Nagata has made this highly mathematical subject understandableto many readers including graduate students in economics. Through the study of variousimportant theoretical problems such as the existence of equilibria, local uniqueness andfiniteness of the set of equilibria, inefficiency of equilibria, etc., Professor Nagata has demonstratedhow successful it is to use mathematics to study important theoretical …

Determinants Of Job Turnover Intentions: Evidence From Singapore, Xiaolin Xing, Zhenlin Yang

Research Collection School Of Economics

This paper explores both observable and unobservable variables that would affect employed workers’ decisions on job change. We find that age, job satisfaction, satisfaction with working environment or job security, and firm size are among the major factors determining workers’ intentions of job-to-job mobility. Younger workers and workers in smaller firms are more likely to look for other jobs. We also find that men are more likely to consider a change in job than women, but when “actually looking for another job” is concerned, men and women do not differ. Furthermore, monthly income and working sector contribute significantly to looking …

Preface--International Legal Dimensions Of Art And Cultural Property, Jeffrey A. Schoenblum

Vanderbilt Journal of Transnational Law

The market for art and cultural property is international.' Demand is intense and not particularly local in terms of consumer preference. Supply responds to this intense international demand. Like most anything else, art finds its way to whomever is prepared to pay for it. Regulation affects how it arrives at its ultimate destination, but generally does not prevent it from getting there...

The symposium's contributors have sought to address the complex legal and policy issues raised by an explosive global market in art and cultural property. These articles will prove invaluable in the shaping of the international legal response to …

Damages For Mental Distress And Other Intangible Loss In A Commercial Context, Shannon O'Byrne

Dalhousie Law Journal

As a general rule, contracts law does not permit an award of general damages for mental distress or other intangible loss. There are several rationales for this, including: plaintiffs are to bear their disappointment or upset with mental fortitude; without the rule, courts would be awash in litigation since every breach of contract brings with it some degree of emotional distress; without the rule, plaintiffs may fabricate or exaggerate the degree of their upset; and the rule simply reflects the lack of foreseeability of such loss under Hadley v. Baxendale. Notwithstanding the general rule, courts have awarded mental distress in …

Relationships Of Intercropped Maize, Stem Borer Damage To Maize Yield And Land-Use Efficiency In The Humid Forest Of Cameroon, A. Chabi-Olaye, C. Nolte, F. Schulthess, C. Borgemeister

All Peer-Reviewed Publications

Stem borers are the most important maize pests in the humid forest zone of Cameroon. Field trials were conducted in the long and short rainy seasons of 2002 and 2003 to assess the level of damage and yield reductions caused by stem borers in monocropped maize and in maize intercropped with non-host plants such as cassava, cowpea and soybean. The intercrops were planted in two spatial arrangements, i.e. alternating hills or alternating rows. All intercrops and the maize monocrop were grown with and without insecticide treatment for assessment of maize yield loss due to borer attacks. The land-use efficiency of …

The Nature And Enforcement Of Investor Rights Under Investment Treaties: Do Investment Treaties Have A Bright Future, Susan Franck

Scholarly Articles in Law Reviews & Journals

The number of investment treaties has surged in the past decade. Even now, the United States and Canada are actively engaged in programs designed to facilitate the completion of multilateral treaties such as the Dominican Republic-Central American Free Trade Agreement (CAFTA-DR) and Bilateral Investment Treaties (BITs). These investment treaties act like economic bills of rights, which grant foreign investors substantive protections and procedural rights to facilitate investment. Sovereigns, meanwhile, may benefit from these treaties by obtaining increased foreign direct investment, which may promote the development of their country's infrastructure 6 and offer citizens basic services including access to clean water, …

Review Of Perilous Voyages: Czech And English Immigrants To Texas In The 1870s By Lawrence H. Konecny And Clinton Machann, Eva Eckert

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Perilous Voyages exemplifies the fact that one can learn much about immigration by focusing on specific journeys. As Konecny and Machann show, this focus enables readers to view immigration as a set of complex decisions of troubled individuals rather than as a movement of masses. The authors have unearthed critical historical materials that shed new light on Texas immigration. The book communicates not only valuable facts but also excitement over discovering previously unpublished materials of narrative interest and historical power: Texas travel adventure in the diary of William Wright (April-May 1879), oral history about the voyage of thirty-six Moravians (1873), …

The Finding Of Echinostoma (Trematoda: Digenea) And Hookworm Eggs In Coprolites Collected From A Brazilian Mummified Body Dated 600–1,200 Years Before Present, L. Sianto, Karl J. Reinhard, M. Chame, S. Chaves, S. Mendonça, M. L. C. Gonçalves, A. Fernandes, L. F. Ferreira, A. Araújo

School of Natural Resources: Faculty Publications

The identification of parasites from ancient cultures expands our list of parasites infective to extant humans. A partially mummified human body from the archeological site of Lapa do Boquete, Minas Gerais State, Brazil, was recently discovered. It was interred between 600 and 1,200 yr ago. Dietary analysis showed that the mummified body was from a society that had a mixed subsistence of agriculture and gathering of wild foods. Coprolites from the body contained numerous helminth eggs. The eggs were identified as those of Echinostoma sp. and hookworm. Hookworm infection in pre-Columbian populations is already established, but this is the first …

Upfc Control Employing Gradient Descent Search, William M. Siever, Radha P. Kalyani, Mariesa Crow, Daniel R. Tauritz

Electrical and Computer Engineering Faculty Research & Creative Works

Increasing demand coupled with limitations on new construction indicate that existing power transmission must be better controlled in order to continue reliable operation. Recent advances in FACTS devices provide a mechanism to better control power flow on the transmission network. One particular device, the unified power flow controller (UPFC), holds the most promise for maintaining operation even when the system has suffered partial failure (either naturally occurring, due to human error, or a malicious attack). In addition to the capital cost, the primary obstacles to widespread UPFC use are the combined problems of selecting the most cost effective locations for …

Use Of 16s Rrna Gene Terminal Restriction Fragment Analysis To Assess The Impact Of Solids Retention Time On The Bacterial Diversity Of Activated Sludge, Pascal E. Saikaly, Peter George Stroot, Daniel B. Oerther

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Terminal restriction fragment length polymorphism (T-RFLP) analysis of 16S rRNA genes was used to investigate the reproducibility and stability in the bacterial community structure of laboratory-scale sequencing batch bioreactors (SBR) and to assess the impact of solids retention time (SRT) on bacterial diversity. Two experiments were performed. In each experiment two sets of replicate SBRs were operated for a periods of three times the SRT. One set was operated at an SRT of 2 days and another set was operated at an SRT of 8 days. Samples for T-RFLP analysis were collected from the two sets of replicate reactors. HhaI, …

OBJECTIVE: Blood stream infection (BSI) is the leading cause of morbidity and mortality in pediatric patients. This study aims to describe the clinical, microbiological characteristics and outcome of BSI in pediatric patients. METHODS: We collected the clinical data from all pediatric patients with positive blood cultures. We identified all isolates from these patients from January 2004 to December 2004 at King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia, and determined antimicrobial susceptibilities by MicroScan Walk Away 96 (Dade Behring Inc., West Sacramento, CA95691, USA). RESULTS: Two hundred and twenty pediatric patients had BSI, of whom 147 (67%) were males and …

Neonatal Infravesical Obstruction In Females, Fayez T. Hammad, Vipul A. Upadhyay

Saudi Medical Journal

Neonatal infravesical obstruction in females is less common than in boys and rarely reported. In this article, we report on 3 cases of infravesical obstruction in female neonates with different etiologies. We also reviewed the literature on this topic. Including our cases, 17 cases of neonatal infravesical obstruction in girls have been reported. Neonatal infravesical obstruction in females has different underlying pathology compared to boys with congenital tumors being more common in girls. A high index of suspicion is essential for early recognition and management.

Trade Mark Dilution In Singapore: The Aftermath Of Mcdonald’S V Mactea, David Llewelyn

Research Collection Yong Pung How School Of Law

In a unanimous decision delivered in September 2004, the Court of Appeal of Singapore has ruled against McDonald's Corporation in its attempts to stop a small Singapore company, Future Enterprises Pty Ltd, from registering its marks "MacNoodles", "MacTea" and "MacChocolate". This case has international significance as the Singapore court ruled, confirming the position taken by courts in a number of other jurisdictions, that McDonald's did not have an exclusive right over the prefix "Mc" in relation to food and beverages in the absence of deception or confusion. However, Singapore's trade mark laws have since undergone a major revamp. Under the …

And/Or Graph And Search Algorithm For Discovering Composite Web Services, Qianhui (Althea) Liang, Stanley Y. W. Su

Research Collection School Of Computing and Information Systems

This paper presents a formalization of the Web Service composition problem as a search problem in an AND/OR graph, and a search algorithm for searching the graph to identify composite service(s) that satisfies a Web Service request. Given a service request that can only be satisfied by a composition of Web Services, we identify the service categories that are relevant to the request and dynamically construct an AND/OR graph to capture the input/output dependencies among the Web Services of these service categories. The graph is modified, based on the information provided in the service request. The search algorithm is then …
