Analysis Of Assessment And Learning Strategies For A Logistics Undergraduate Education Programme, Margaret Farrell

Conference Papers

It is recognised that in today’s global competitive marketplace, where outsourcing continues to grow at an exponential rate, Logistics and Supply Chain Management (SCM) have grown in importance [1]. Research suggests that as logistics moves from being viewed as a stand alone discipline to one viewed as integrating the management of supply, the duties, managerial skills and knowledge of the Professional Logistician have changed [2] [3] . The challenge for logistics educators is to design and develop curricula, learning, teaching and assessment strategies that can support wide-ranging and integrative learning objectives. Research also states that universal logistics management skills must …

Critical Junctures? Privatization Policy In Brazil And Argentina At The Start Of The Century, John Hogan

Articles

This paper uses the critical junctures framework developed by Hogan and Doyle (2007) to determine if there were critical junctures in privatization policy in Brazil and Argentina at the start of the 21st century. The framework constitutes a rigorous approach to the identification of crisis, ideational change, and policy change. It is used to examine the economic disasters in Brazil in 1999 and Argentina in 2001. Previously, we would have had to wait decades before making such an assessment, as there were few tools with which to identify critical junctures, and these were usually only effective long after the event.

Dynamical Pattern Formation During Growth Of A Dual-Species Bose-Einstein Condensate, Shai Ronen, John L. Bohn, Laura Elisa Halmo, Mark Edwards

Physics & Astronomy: Faculty Publications

We simulate the growth of a dual species Bose-Einstein condensate using a Gross-Pitaevskii equation with an additional gain term giving rise to the growth. Such growth occurs during simultaneous evaporative cooling of a mixture of two gases. The ground state of a dual condensate is normally either a miscible mixture, or an immiscible phase with two spatially separated components. In a cigar trap the ground state typically consists of one component in the center, and the other component flanking it. Our simulations show that when the condensates are formed in a cigar trap and the mixture is phase separated, then …

The Effect Of Graphic Organizers On The Academic Achievement Of High School Students In United States History Who Receive Instruction In A Blended, Computer-Based Learning Environment, George Kim Conley

Doctoral Dissertations and Projects

The purpose of this study was to investigate the effect of graphic organizers on the academic achievement of high school students receiving instruction in United States History via an online blended learning environment. With 60 participants in the study, the students were equally divided into two groups of 30 participants each. Group I was designated as the treatment group, while Group II formed the control group. A two-tailed t-test was used to determine that the means of the two posttests were not significantly different at a probability level of .05. Therefore, the results of this research study indicated that high …

Revisiting Unitarity Corrections For Electromagnetic Processes In Collisions Of Relativistic Nuclei, Ulrich D. Jentschura, Kai Hencken, Valery G. Serbo

Physics Faculty Research & Creative Works

Unitarity corrections to several electromagnetic processes in collisions of relativistic heavy nuclei are considered. They are due to the unitarity requirement for the S-matrix and correspond to the exchange of a light-by-light scattering block between colliding nuclei. We obtain improved results for the corrections to e⁺ e^- and μ⁺ μ^- pair production as well as new results for unitarity corrections to the production of photons via virtual Compton and virtual Delbrück scattering. These corrections can be numerically large; e.g., the μ⁺ μ^- pair production cross section is reduced by about 50% and nuclear bremsstrahlung …

New (E,2e) Studies Of Atomic And Molecular Targets, E. M. Staicu-Casagrande, A. Naja, A. Lahmam-Bennani, A. S. Kheifets, Don H. Madison, B. Joulakian

Physics Faculty Research & Creative Works

We report new coplanar (e,2e) measurements characterised by large energy transfer and close to minimum momentum transfer from the projectile to the target. Ionisation of the two-electron targets He and H₂ is investigated under these particular kinematics. The experimental data are compared with the predictions of the most elaborate theoretical models. The obtained good agreement motivated us to extend our research to the case of more complex targets such as Ar. Comparison with the most elaborate models in the case of multi-electron targets is excellent. Destructive and constructive interference effects in the case of H₂ are observed and …

Directed Altruism And Enforced Reciprocity In Social Networks, Stephen Leider, Markus M. Mobius, Tanya S. Rosenblat, Quoc-Anh Do

Research Collection School Of Economics

We conducted online field experiments in large real-world social networks in order to decompose prosocial giving into three components: (1) baseline altruism toward randomly selected strangers, (2) directed altruism that favors friends over random strangers, and (3) giving motivated by the prospect of future interaction. Directed altruism increases giving to friends by 52% relative to random strangers, whereas future interaction effects increase giving by an additional 24% when giving is socially efficient. This finding suggests that future interaction affects giving through a repeated game mechanism where agents can be rewarded for granting efficiency-enhancing favors. We also find that subjects with …

Future Fiscal And Budgetary Shocks, Hian Teck Hoon, Edmund S. Phelps

Research Collection School Of Economics

We study the effects of future tax and budgetary shocks in a non-monetary and possibly non-Ricardian economy. An (unanticipated) temporary labor tax cut to be effective on a given future date—a delayed “debt bomb”—causes at once a drop in the (unit) value placed on the firms' business asset, the customer, with the result that share prices, the hourly wage, and employment drop in tandem. This paradox of reduced activity through announcement of future “stimulus” does not hinge on an upward jump of long interest rates. A future tax-rate cut lacking a “sunset” provision has the same negative effects.

Can A Representative Agent Model Represent A Heterogeneous Agent Economy?, Sungbae An, Yongsung Chang, Sun-Bin Kim

Research Collection School Of Economics

Accounting for observed fluctuations in aggregate employment, consumption, and real wage using the optimality conditions of a representative household requires preferences that are incompatible with economic priors. In order to reconcile theory with data, we construct a model with heterogeneous agents whose decisions are difficult to aggregate because of incomplete capital markets and the indivisible nature of labor supply. If we were to explain the model-generated aggregate time series using decisions of a stand-in household, such a household must have a nonconcave or unstable utility as is often found with the aggregate US data.

A New Framework For The Design And Analysis Of Identity-Based Identification Schemes, Guomin Yang, Jing Chen, Duncan S. Wong, Xiaotie Deng, Dongsheng Wang

Research Collection School Of Computing and Information Systems

Constructing an identification scheme is one of the fundamental problems in cryptography, and is very useful in practice. An identity-based identification (IBI) scheme allows a prover to identify himself to a public verifier who knows only the claimed identity of the prover and some public information. In this paper, we propose a new framework for both the design and analysis of IBI schemes. Our approach works in an engineering way. We first identify an IBI scheme as the composition of two building blocks, and then show that, with different security properties of these building blocks, the corresponding IBI schemes can …

Lifestyle Of Shellmound Builders In Brazil (Galley Proofs), Sabine Eggers, C. C. Petronilho, K. Brandt, J. Filippini, Karl J. Reinhard

School of Natural Resources: Faculty Publications

The contact of inland and coastal prehistoric groups in Brazil is believed to have been restricted to regions with no geographical barrier, as is the case in the Ribeira de Iguape valley. The inland osteological collection from the riverine shellmound Moraes (5800–4500 BP) represents a unique opportunity to test this assumption for this region. Despite cultural similarities between riverine and coastal shellmounds, important ecological and site distribution differences are expected to impact on lifestyle. The purpose of this study is thus to document and interpret health and lifestyle indicators in Moraes in comparison to coastal shellmound groups. Specifically we test …

Regulation Of Oviposition In Anopheles Gambiae S.S.: Role Of Inter- And Intra-Specific Signals, Leunita A. Sumba, C. Brandon Ogbunugafor, Arop L. Deng, Ahmed Hassanali

All Peer-Reviewed Publications

Females of Anopheles gambiae Giles normally oviposit in a large number of fresh, small, sunlit, and spatially spread temporary pools. Such pools are associated with lower levels of predation compared to large, longer-lasting habitats. We compared oviposition levels on preferred (water collected from natural anopheline larval habitats) and non-preferred (distilled water) aqueous substrates by gravid females that contained different densities of conspecific eggs or early and late instar larvae. The presence of conspecific larvae, but not eggs, had a positive or negative effect on the ovipositional responses of gravid An. gambiae females, depending on the quality (preferred or non-preferred by …

The Past, Present, And Future Of The United Nations: A Comment On Paul Kennedy And The Parliament Of Man (El Pasado Como Prologo: El Futuro Glorioso Y El Turbio Presente De Las Naciones Unidas (Revista De Paul Kennedy, El Parlamento De La Humanidad)), Kenneth Anderson

Scholarly Articles in Law Reviews & Journals

American University, WCL Research Paper No. 2008-72 Abstract: This is the original Spanish language version of an essay (10,000 words) appearing in the Revista de Libros (Madrid), considering the history and future of the United Nations and global governance through the lens of Paul Kennedy's recent work, The Parliament of Man. The essay is highly skeptical of what it describes as platonism about the future of the UN as the seat of global governance. It offers an alternative view of how to consider the work of the UN, in three areas: security, economic development, and values. The essay argues that, …

Masters Theses & Doctoral Dissertations

In the current growing online commodity market, opinion survey plays a major role for the enhancement of the business. Many organizations prefer theses surveys in order to improve their service and market from the user feedback. Organizations would like to have a database system which allows them to get user opinions on different platforms like product websites, blogs, discussion groups, etc. They want the system to store the date, time and the text of opinion every time, the user enters an opinion on any platform. Some platforms allow the user to give a numeric score for the product. Score range …

Overvaluing Uniformity, Amanda Frost

Scholarly Articles in Law Reviews & Journals

"E NSURING the uniform interpretation of federal law has long been considered one of the federal courts' primary objectives, and uniformity is regularly cited in some of the most intractable debates about the structure and function of the federal court system. For example, specialized courts are lauded for their ability to ensure uniformity in the areas of law over which they have jurisdic- tion. Similarly, proponents of exclusive federal jurisdiction contend that the federal courts provide greater consistency in the interpre- tation of federal law than could fifty different state courts. Some commentators claim that Congress' power to create exceptions …

Analyzing The Catalytic Mechanism Of The Fe-Type Nitrile Hydratase From Comamonas Testosteroni Ni1, Saroja Rao, Richard C. Holz

Chemistry Faculty Research and Publications

In order to gain insight into the catalytic mechanism of Fe-type nitrile hydratases (NHase), the pH and temperature dependence of the kinetic parameters k_cat, K_m, and k_cat/K_m along with the solvent isotope effect were examined for the Fe-type NHase from Comamonas testosteroni Ni1 (CtNHase). CtNHase was found to exhibit a bell-shaped curve for plots of relative activity vs pH over pH values 4−10 for the hydration of acrylonitrile and was found to display maximal activity at pH ∼7.2. Fits of these data provided a pK_ES1 value of …

Diagnosis And Management Of Piriformis Syndrome: An Osteopathic Approach, Lori A. Boyajian-O'Neill, Rance Mcclain, Michele K. Coleman, Pamela P. Thomas

Faculty and Staff Publications

Piriformis syndrome is a neuromuscular condition characterized by hip and buttock pain. This syndrome is often overlooked in clinical settings because its presentation may be similar to that of lumbar radiculopathy, primary sacral dysfunction, or innominate dysfunction. The ability to recognize piriformis syndrome requires an understanding of the structure and function of the piriformis muscle and its relationship to the sciatic nerve. The authors review the anatomic and clinical features of this condition, summarizing the osteopathic medical approach to diagnosis and management. A holistic approach to diagnosis requires a thorough neurologic history and physical assessment of the patient based on …

Regulating Self-Organizing Nanostructures Via External Mechanism, Jiangyu Li, Q. G. Du, Stephen Ducharme

Stephen Ducharme Publications

Self-organizing nanostructures are ubiquitous in both natural and synthetic materials. They are not only appealing scientifically, by revealing the intrinsic atomic and molecular interactions that might be difficult to detect otherwise, but may also hold the key for the development of novel functional structures and devices. For their technological potential to be fully realized, the size, morphology, and distribution of the self-organizing nanostructures must be regulated. In this paper, we investigate the principles under which the self-organizing nanostructures can be regulated via external mechanisms. Using nanomesa and nanowell formation in polyvinylidene fluoride trifluoroethylene copolymer film as an example, we demonstrate …

Flush-Mounted Steady-Periodic Heated Film With Application To Shear-Stress Measurement, Kevin D. Cole

Department of Mechanical and Materials Engineering: Faculty Publications

Surface-mounted heated films have been used for fluid-flow measurement for many years. Recently unsteady heating of such surface films has been explored experimentally. In this paper steady-periodic heating of a surface-mounted film is studied analytically. Wall effects and axial heat conduction in the fluid are included. The temperature is found as an exact integral expression constructed from separate Green’s function formulations in the fluid flow and in the solid wall that are matched at the fluid-solid interface. Results for temperature, obtained by quadrature, are reported for several flow speeds and several steady-periodic frequencies. The results show that steady-periodic heating has …

Correlation Between Eut Failure Levels And Esd Generator Parameters, Jayong Koo, Qing Cai, Kai Wang, J. Maas, T. Takahashi, Andrew Martwick, David Pommerenke

Electrical and Computer Engineering Faculty Research & Creative Works

Some system-level electrostatic discharge (ESD) tests repeat badly if different ESD generators are used. For improving repeatability, ESD generator specifications have been changed, and modified generators have been compared in a worldwide round robin test. The test showed up to 1 : 3 variations of failure levels. Multiple parameters that characterize ESD generators have been measured. This paper correlates the parameters to test result variations trying to distinguish between important and nonrelevant parameters. The transient fields show large variations among different ESD generators. A correlation has been observed in many equipment under tests (EUTs) between failure levels and the spectral …

Indirect Camera Calibration In A Medical Environment, Bennet Tillapaugh

Theses

This thesis addresses the need to have calibrated cameras in surgery rooms. Data can then be collected during surgeries to assist the surgeons and it can later be used for postoperation analysis. Typical techniques for camera calibration are not adequate for a medical environment due to the cameras constantly moving and with no rigid area always in the cameras’ view. The proposed approach is to calibrate cameras attached to surgical lights by utilizing extra cameras placed on the ceiling. The ceiling cameras find the position of the light cameras and calibrate their extrinsic parameters. This indirect calibration method provides an …
