Personal Jurisdiction In Comparative Context, Scott Dodson Jan 2021

Personal Jurisdiction In Comparative Context, Scott Dodson

Faculty Scholarship

This Article places the recent evolution of U.S. personal jurisdiction in comparative context. Comparativism helps illuminate and explain both the modest convergences and the more pervasive divergences. On the convergences side, the Supreme Court’s acknowledgment of transnational litigation and express invocation of European approaches to personal jurisdiction have helped move general jurisdiction away from the exorbitant “doing business” jurisdiction that seemed previously to be settled U.S. law. But persistent divergences tell the more interesting story. The Court’s refusal to deviate from its commitment to transient jurisdiction, its recent narrowing of specific jurisdiction since 2011, its implicit rejection of pendent-party personal …

Articles, Abstracts, and Reports

The demand for food will outpace productivity of conventional agriculture due to projected growth of the human population, concomitant with shrinkage of arable land, increasing scarcity of freshwater, and a rapidly changing climate. While aquaponics has potential to sustainably supplement food production with minimal environmental impact, there is a need to better characterize the complex interplay between the various components (fish, plant, microbiome) of these systems to optimize scale up and productivity. Here, we investigated how the commonly-implemented practice of continued microbial community transfer from pre-existing systems might promote or impede productivity of aquaponics. Specifically, we monitored plant growth phenotypes, …

A Learning Curve Model Accounting For The Flattening Effect In Production Cycles, Evan R. Boone, John J. Elshaw, Clay M. Koschnick, Jonathan D. Ritschel, Adedeji B. Badiru Jan 2021

A Learning Curve Model Accounting For The Flattening Effect In Production Cycles, Evan R. Boone, John J. Elshaw, Clay M. Koschnick, Jonathan D. Ritschel, Adedeji B. Badiru

Faculty Publications

We investigate production cost estimates to identify and model modifications to a prescribed learning curve. Our new model examines the learning rate as a decreasing function over time as opposed to a constant rate that is frequently used. The purpose of this research is to determine whether a new learning curve model could be implemented to reduce the error in cost estimates for production processes. A new model was created that mathematically allows for a “flattening effect,” which typically occurs later in the production process. This model was then compared to Wright’s learning curve, which is a popular method used …

Use Of Factors In Development Estimates: Improving The Cost Analysis Toolkit, Matthew R. Markman, Jonathan D. Ritschel, Edward D. White Jan 2021

Use Of Factors In Development Estimates: Improving The Cost Analysis Toolkit, Matthew R. Markman, Jonathan D. Ritschel, Edward D. White

Faculty Publications

Factor Estimating is a technique commonly used by defense acquisition analysts to develop cost estimations. However, previous studies developing factors for the Engineering and Manufacturing Development (EMD) phase of the life cycle are limited. This research expands the current toolkit for cost analysts by developing cost factors in previously unexplored areas. More specifically, over 400 cost reports are utilized to create new standard cost factors that are delineated by five categories: commodity type, contract type, contractor type, development type, and Service. The factors are developed for those elements that are common in a wide array of projects such as program …

Quantifying The Effects Of Aircraft Engine Upgrades On Operating And Support Costs, Bradford A. Myers, Edward D. White, Jonathan D. Ritschel, R. David Fass Jan 2021

Quantifying The Effects Of Aircraft Engine Upgrades On Operating And Support Costs, Bradford A. Myers, Edward D. White, Jonathan D. Ritschel, R. David Fass

Faculty Publications

For fixed wing aircraft within the U.S. Air Force, Operating and Support (O&S) costs encompass a large portion of total life cycle costs. O&S costs include fuel, maintenance, and engine upgrades. To the authors’ knowledge, no study to date has attempted to empirically quantify the realized effects of new aircraft engines on sustainment costs. Utilizing the Air Force Total Ownership Cost database, they focused on new engines appearing on the C-5s, C-130s, and C-135s. Although narrow in scope, results suggest newer engines have lower fuel costs. Maintenance costs for newer engines were not consistently higher or lower than the engines …

An Examination Of Factors Influencing National Reputation Of India Among South Asians On Social Media, Nisha Garud-Patkar

Faculty Research, Scholarly, and Creative Activity

Social media play a central role in governments’ communication with foreign citizens, but little is done to understand how such platforms build national reputation. To fill this research gap, the study examines online engagement, online social relations, and information use that predict national reputation in the social media context. National reputation is examined through a survey of 387 South Asian social media followers of the Indian government. Results show that online engagement of users with the Indian government and their information use related to India are positively associated with national reputation. However, users’ online social relations with Indians is negatively …

Solving A Hybrid Batch Production Problem With Unreliable Equipment And Quality Reassurance, Singa Wang Chiu, Hua Yao Wu, Tsu Ming Yeh, Yunsen Wang Jan 2021

Solving A Hybrid Batch Production Problem With Unreliable Equipment And Quality Reassurance, Singa Wang Chiu, Hua Yao Wu, Tsu Ming Yeh, Yunsen Wang

Department of Accounting and Finance Faculty Scholarship and Creative Works

A hybrid batch fabrication plan involving an outsourcing option is often established to deal with the in-house capacity constraint and/or meet timely demand with a reduced cycle time. Besides, the occurrences of unpredictable equipment malfunction and imperfect product quality should also be effectively managed during in-house fabrication to meet the production schedule and the required quality level. To address these concerns, we examine a hybrid economic production quantity (EPQ) problem with an unreliable machine and quality reassurance; wherein, an outside provider helps supply a portion of the batch at a requested timing and desirable quality, but at the price of …

A comprehensive in situ dataset of chlorophyll a (Chl a; N = 18,001), net primary production (NPP; N = 165) and net community production (NCP; N = 95), were used to evaluate the performance of Moderate Resolution Imaging Spectroradiometer on Aqua (MODIS-A) algorithms for these parameters, in the South Atlantic Ocean, to facilitate the accurate generation of satellite NCP time series. For Chl a, five algorithms were tested using MODIS-A data, and OC3-CI performed best, which was subsequently used to compute NPP. Of three NPP algorithms tested, a Wavelength Resolved Model (WRM) was the most accurate, and was therefore used …

Evaluating Lamp Assays For Detection Of Phytoplasmas Classified In Different Ribosomal Groups, Naofel Aljafer, Mathew Dickinson Jan 2021

Evaluating Lamp Assays For Detection Of Phytoplasmas Classified In Different Ribosomal Groups, Naofel Aljafer, Mathew Dickinson

School of Biological and Marine Sciences

A new set of loop-mediated isothermal amplification assays was developed for detection of phytoplasmas associated with plant diseases and optimised for rapid laboratory detection. This set of assays was designed based on the leucyl tRNA synthetase gene expressed in most of the phytoplasmas and showing a good level of sequence divergence among strains from different 16Sr groups. This makes it a good target for developing discrete assays that can detect specific phytoplasma 16Sr groups. In this study, unique sets of LAMP assays were designed and validated for seven phytoplasma ribosomal groups (16SrI, 16SrII, 16SrIII, 16SrV, 16SrVI, 16SrX, and 16SrXII). These …

Wave Modulation Of Flows On Open And Closed Reefs, M Lindhart, Js Rogers, Sa Maticka, Cb Woodson, Sg Monismith Jan 2021

Wave Modulation Of Flows On Open And Closed Reefs, M Lindhart, Js Rogers, Sa Maticka, Cb Woodson, Sg Monismith

School of Biological and Marine Sciences

Using observations, numerical models, and theory, we explore a framework to classify reefs as open or closed based on their dynamics. While the concepts of open and closed reefs are used widely in studies of coral reef hydrodynamics and are generally based on geometry, there is no consensus on what qualifies as open and closed. With observations from Ofu, American Samoa, we show that the reef flat exhibits two different dynamical regimes depending on tidal and wave forcing. Flow over this reef flat resembles a classic one‐dimensional barrier reef flow during low tide, where wave setup creates a cross‐reef pressure …

How Consistent Are Estimates Of Roughness Parameters On A Rough Coral Reef?, M Lindhart, Sg Monismith, A Khrizman, D Mucciarone, R Dunbar Jan 2021

How Consistent Are Estimates Of Roughness Parameters On A Rough Coral Reef?, M Lindhart, Sg Monismith, A Khrizman, D Mucciarone, R Dunbar

School of Biological and Marine Sciences

Coral reefs are hydrodynamically rough, creating turbulent boundary layers that transport and mix various scalars that impact reef processes and also can be used to monitor reef health. Often reef boundary layer characteristics derived from a single instrument are assumed to accurately represent the study site. This approach relies on two assumptions: first, that the boundary layer is relatively homogeneous across the area of interest, and second, that two instruments displaced in space or with different spatiotemporal resolution would produce similar results when sampling the same flow. We deployed four velocimeters over a 15 × 20 m reef at 10 …

Situational Judgment Tests: From Low-Fidelity Simulations To Alternative Measures Of Personality And The Person-Situation Interplay, Filip Lievens, Philipp Schäpers, Christoph N. Herde Jan 2021

Situational Judgment Tests: From Low-Fidelity Simulations To Alternative Measures Of Personality And The Person-Situation Interplay, Filip Lievens, Philipp Schäpers, Christoph N. Herde

Research Collection Lee Kong Chian School Of Business

In employment and education settings, Situational Judgment Tests (SJTs) have made strong inroads. So far, however, they are still underutilized in personality research. The objective of this chapter is to outline how SJTs might be adapted to measure personality traits, shed light onto the person-situation interplay, and stimulate research on it. We start by discussing the traditional simulation-based view on SJTs, including information on their development and research results. Next, we show how more recent versions have started to assess people’s knowledge of relevant behavior related to personality traits. Finally, we specify various strategies as to how SJTs might be …

Capm-Based Company (Mis)Valuations, Olivier Dessaint, Jacques Olivier, Clemens A. Otto, David Thesmar Jan 2021

Capm-Based Company (Mis)Valuations, Olivier Dessaint, Jacques Olivier, Clemens A. Otto, David Thesmar

Research Collection Lee Kong Chian School Of Business

There is a discrepancy between CAPM-implied and realized returns. Using the CAPM in capital budgeting -- as recommended in textbooks -- should thus have real effects. For instance, low beta projects should be valued more by CAPM-users than by the market. We test this hypothesis using M&A data and show that bids for low-beta private targets entail lower bidder returns. We provide further support by testing several ancillary predictions. Our analyses suggest that using the CAPM when valuing targets leads to valuation errors (relative to the market's view) corresponding on average to 12% to 33% of the deal values.

Crowdfunding Digital Platforms: Backer Networks And Their Impact On Project Outcomes, Yee Heng Tan, Srinivas K. Reddy Jan 2021

Crowdfunding Digital Platforms: Backer Networks And Their Impact On Project Outcomes, Yee Heng Tan, Srinivas K. Reddy

Research Collection Lee Kong Chian School Of Business

Crowdfunding platforms serve to connect project creators and backers. Previous research has explored several project and platform determinants that impact crowdfunding outcomes. However, there has been limited research on these determinants at an individual level. Our paper addresses how backers may influence the outcomes of projects in crowdfunding platforms. We explore several methods commonly used in the industry to identify influence and show that centrality measures through a backer affiliation network best exemplifies influence. Using data from Kickstarter, we construct a weighted backer network based on 52,678 common projects backed by 11,134 backers. Controlling for digital media mentions and project …

Globalization And Affordability Of Microfinance, Sunny Li Sun, Hao Liang Jan 2021

Globalization And Affordability Of Microfinance, Sunny Li Sun, Hao Liang

Research Collection Lee Kong Chian School Of Business

We study how globalization can differentially affect financial inclusion through the lens of microfinance. Based on an institutional logics perspective, we argue that MFIs embody both social logic and market logic with regard to provision of affordable microfinance loans. Speicially, social logic is amplified by greater social globalization and the stronger presence of nonprofit organizations (NPOs) in the microfinance industry. In contrast, economic globalization catalyzes MFIs' market logic, leading to weaker or greater affordability of microfinance, depending on the relative strength of the profit-maximizing motive and real competition. We test these predictions by focusing on MFI interest-rate setting and using …

Pay For Performance: When Does It Fail?, Nirmalya Kumar, Madan Pillutla Jan 2021

Pay For Performance: When Does It Fail?, Nirmalya Kumar, Madan Pillutla

Research Collection Lee Kong Chian School Of Business

The consensus in social psychology is that monetary incentives for performance have a detrimental impact on individual performance. Yes, under certain specific and limited conditions, rewards can reduce performance. Yet pay for performance schemes are ubiquitous. How can we resolve this divergence between theoretical recommendations and observed practices? Nirmalya Kumar and Madan Pillutla recommend solving the problem by designing smarter incentives that avoid these detrimental effects.

Innovation Governance In Chinese Family Business: A Case Study, Thomas Menkhoff, Geok Chwee Ong

Research Collection Lee Kong Chian School Of Business

Corporate innovation governance can be defined as a systematic approach to align goals, allocate resources and assign decision-making authority for innovation, across the company and with external parties. While the dos and don’ts of innovation governance approaches in non-Asian firms are fairly well researched, little is known about the Chinese way of governing innovation in Asian family firms. This paper provides insights into the innovation management capabilities of Qian Hu, an integrated ornamental fish service provider incorporated in Singapore in 1998. Based on half-structured interviews with its Executive Chairman and MD Mr. Kenny Yap, we exemplify the key components of …
