ECONOMIC THRESHOLDS UNDER UNCERTAINTY WITH APPLICATION TO CORN NEMATODE MANAGEMENT

An economic threshold of agricultural pest management is derived. Results provide a method for researchers to use in making improved pest control recommendations to farmers without farm level decision-making. An empirical illustration for lesion nematode management in irrigated corn is given and directions for further research are indicated.Crop Production/Industries, Risk and Uncertainty,

New England's Installed Electric Generation Forecast 2013-2025

The aim of this Master’s Project, as identified by our client the C Three Group, LLC, was to forecast installed electric capacity in the ISO New England region through the year 2025 under different scenarios including varying natural gas prices and RPS programs. ISO New England is the Independent System Operator of New England and oversees electric generation and transmission in the New England States. Our team built a basic supply model and, using linear optimization, we estimated ways for the ISO New England region to expand its supply to meet the growth in forecast demand. We ran our model under different scenarios, including varying natural gas prices and RPS programs. We took into account announced changes to capacity as well as possible scenarios that may affect further changes in the makeup of capacity. The final results showed continued expansion of natural gas and wind generation, the low-cost leaders, as well as new development of demand response. As we varied the future prices of natural gas, more electricity began to be imported from Canada. We believe that future carbon prices and stricter RPS standards may further ratchet up imports and renewables, in place of natural gas. Finally, our model predicts possible future coal retirements and is doubtful of new nuclear. Our client will potentially use the explanation of our models and written report of our findings in future research and consulting for their business

A leadership identity development model: Applications from a grounded theory

This article describes a stage-based model of leadership identity development (LID) that resulted from a grounded theory study on developing a leadership identity (Komives, Owen, Longerbeam, Mainella, & Osteen, 2005). The LID model expands on the leadership identity stages, integrates the categories of the grounded theory into the LID model, and develops how the categories of the theory change across stages of the model. The model has implications for working with individuals as they develop their leadership identity and for facilitating groups as they develop empowering environments for shared leadership. Connections to related scholarship and stage-based implications for practice are explored

Developing a leadership identity: A grounded theory

This grounded theory study on developing a leadership identity revealed a 6-stage developmental process. The thirteen diverse students in this study described their leadership identity as moving from a leader-centric view to one that embraced leadership as a collaborative, relational process. Developing a leadership identity was connected to the categories of developmental influences, developing self, group influences, students' changing view of self with others, and students' broadening view of leadership. A conceptual model illustrating the grounded theory of developing a leadership identity is presented

Breast Cancer Presenting as Unilateral Arm Edema

CONTEXT: Symptomatic arm lymphedema as the presenting symptom of invasive breast carcinoma is a rare occurrence. DESIGN: We report a case of invasive breast cancer presenting with unilateral arm swelling. The patient was initially thought to have venous thrombosis. A thorough physical examination and a mammogram revealed the presence of breast cancer and associated subclinical axillary lymphadenopathy. CONCLUSION: Failure to recognize this presentation can lead to misdiagnosis or a significant delay in diagnosis and treatment
