    Working Paper No. 42, Commodity Production as an Explanatory Variable in the Outbreak of the American Civil War

    Get PDF
    This inquiry seeks to establish that the American South’s comparative advantage in primary commodity production can be identified as an explanatory variable in the outbreak of the American Civil War. In addition, this inquiry seeks to illustrate the positive historical correlation between a state’s reliance on primary commodity production and its propensity to generate extreme outcomes—namely, institutional inequality, conflict, and civil war. Furthermore, this inquiry seeks to demonstrate that civil wars can be primarily understood as a function of a rebelling force’s economic motivations and explores the concept of King Cotton, westward expansion, and the South’s ultimate secession from the Union as a function of the winner’s curse

    What Christian Leaders Can Learn From Lean

    Get PDF
    The term “Lean” was coined by researchers at MIT in the 1980s to describe the methods developed by Toyota in post-war Japan to first survive, then thrive, and ultimately dominate the global automotive industry. Beyond shop floor techniques for setup reduction or just-in-time inventory control, Lean evolved into a management system with principles that apply in any context. This paper presents the foundational principles of Lean and explores their striking similarities with biblical teachings. These similarities are both noteworthy and surprising, since Lean was developed in a non-Christian cultural and religious context. We contend that Christian leaders can learn from Lean and suggest ways of applying Lean principles that will strengthen their work, be it in business, ministry or church

    US hospital performance: A dynamic network analysis

    Get PDF
    Workshop 2013 on Dynamic and Network DEA (January 29-30, 2013)Healthcare is a critical and costly industry. In the U.S. a significant component of healthcare costs are expenses generated in hospitals. This paper reports the results of analyzing 607 U.S. hospitals between 2006-2009 using a dynamic network slack-based Data Envelopment Analysis (DEA) Model. We find accounting for the dynamic and network structure of the hospital lowers efficiency estimates. Further, hospitals are more efficient at providing hospital services compared to hotel services, but the efficiency of hospitals is not correlated with their size. Regarding the dynamic network slack-based DEA Model, we find slack-based approaches combine technical and allocative aspects of inefficiency and thus tend to have significantly lower efficiency levels than just radial technical efficiency measures. Further when applying an envelopment method like DEA, there are some benefits to averaging multiple years of data to remove variation and avoid estimating a frontier based on observations that might have significant noise in their measurement.This workshop is supported by JSPS KAKENHI Grant Number 22310092 under the title “Theory and Applications of Dynamic DEA with Network Structure.

    Modelling sediment supply and transport in the River Lugg: strategies for controlling sediment loads

    Get PDF
    The River Lugg has particular problems with high sediment loads that have resulted in detrimental impacts on ecology and fisheries. A new dynamic, process-based model of hydrology and sediments (INCA- SED) has been developed and applied to the River Lugg system using an extensive data set from 1995–2008. The model simulates sediment sources and sinks throughout the catchment and gives a good representation of the sediment response at 22 reaches along the River Lugg. A key question considered in using the model is the management of sediment sources so that concentrations and bed loads can be reduced in the river system. Altogether, five sediment management scenarios were selected for testing on the River Lugg, including land use change, contour tillage, hedging and buffer strips. Running the model with parameters altered to simulate these five scenarios produced some interesting results. All scenarios achieved some reduction in sediment levels, with the 40% land use change achieving the best result with a 19% reduction. The other scenarios also achieved significant reductions of between 7% and 9%. Buffer strips produce the best result at close to 9%. The results suggest that if hedge introduction, contour tillage and buffer strips were all applied, sediment reductions would total 24%, considerably improving the current sediment situation. We present a novel cost-effectiveness analysis of our results where we use percentage of land removed from production as our cost function. Given the minimal loss of land associated with contour tillage, hedges and buffer strips, we suggest that these management practices are the most cost-effective combination to reduce sediment loads

    Mindful Organizing for the CIO: Towards a Conceptual Model for Transformational Leadership

    Get PDF
    Considered invaluable to corporate entities, CIOs are relied upon for the strategic oversight of technological infrastructure as well as the articulation of a business case for IT resources. How can CIOs prepare for and respond to dynamic, and often uncertain changes, which challenge organizational resources, processes, and strategies? Research continues to indicate that technological transformation and integration of newer, faster IT capabilities have become a critical focus for the CIO. Extant literature on mindfulness suggests that mindful organizing (MO) can facilitate and enhance the effectiveness of strategic level decision makers. Integrating insights from MO, we present and analyze the literature to build an action orientated framework to support the CIO in leveraging the dynamic capabilities under his/her purview. Our objective is to examine key attributes of mindful organizing which are especially critical to building a level of awareness that cultivates an environment for reliability under transformational leaders

    A MINDFULNESS BASED APPROACH TO EMERGENCY MANAGEMENT INFORMATION SYSTEMS (EMIS) UTILIZATION AND PERFORMANCE

    Get PDF
    The 13th of November terrorist attacks in Paris highlight a critical need within the emergency management (EM) domain to demonstrate the value of technological system capacities that support decision making. The world watched scores of police, paramedic, and fire teams communicating and coordinating together to save innocent civilian lives. Many researchers agree that systems should be designed informed by the “cognitive processes” used to respond to unanticipated emergencies. Mindfulness, within emergency management organizations (EMOs,) is created by the complex engagement of five organizational principles. They activate processes which produce capabilities uniquely supported by technology to anticipate and contain unexpected incidents for the EM domain. This paper explores organizational mindfulness (OM)) as a theoretical and methodological mechanism for design, assess and evaluation of emergency management information systems (EMIS). Mindfulness provides a basis for understanding both the EM domain and the organizational capabilities which allow for multiagency coordination. Design Science is proposed to conceptualize an IS artefact that refines our understanding of coordinated real- time decision making (CRDM). This research-in-progress paper adds to literature focused on system utilization and performance through the lens of the EM domain focusing on EMIS utilization to engage in CRDM within operational centres

    Non-additive response of the high-latitude Southern Hemisphere climate to aerosol forcing in a climate model with interactive chemistry

    Get PDF
    A suite of chemistry‐climate model simulations, forced by pairs of anthropogenic forcings [comprising greenhouse gases (GHGs), ozone depleting substances (ODSs), or aerosols], were employed to investigate whether the high‐latitude Southern Hemisphere (SH) circulation response to these forcings is linearly additive, a common assumption in attribution studies. We find that the geographical pattern of sea‐level pressure (SLP) response to a combination of GHGs and ODSs is linearly additive. However, we find significant differences in the SLP response when combining GHGs and aerosols compared to the sum of the individual forcings, a non‐additivity that is currently masked by the dominance of the ODSs forcing. This non‐linearity also results in changes to the SH split jet. These results were obtained using a coupled chemistry‐climate model, indicating that the non‐linear response is due to chemical interactions between the forcing agents. As such, future simulations investigating a post‐ozone hole Southern Hemisphere climate should consider this chemical interaction

    Capturing multi-stakeholder needs in Customer-Centric Cloud Service Design

    Get PDF
    Cloud computing applications and services go hand in hand, yet there is no clear mechanism for ensuring that the cloud applications are designed from a customer’s perspective. Likewise services can require adaptation for multiple customers of stakeholders, which require differing user experience outcomes. This paper describes the initial design and development of a predictive analytics cloud service application, which uses historic customer data to predict the existing customers that are most likely to churn. Service blueprinting, a service innovation method, was used as the underlying design model for developing an initial shared understanding of the required service. Personas were used in the requirements analysis to develop insights into multi-stakeholder needs. Using the design science paradigm an extended cloud service design theory is proposed, as an outcome of the ongoing development of this analytics platform
