Distribution, Status, and Life History Aspects of Two Rare Logperches, Percina burtoni and Percina apina

The Blotchside Logperch, Percina burtoni, and Tennessee Logperch, Percina apina, are Tennessee-Cumberland River drainage endemics that have experienced range reductions due to anthropogenic influences. All known collection records were gathered to fully describe the historical distribution of these species for comparison to their currently inhabited range. Discussion of major impacts to rivers that contain or contained these species is included for an understanding of factors that may have influenced contemporary distributions. Extensive field surveys were conducted during 2014 to 2017 to aid in determination of the current status and distribution of populations. New information of previously unreported or undetected populations, population status, life history observations, and longevity estimates are presented

Coercive Region-level Registration for Multi-modal Images

We propose a coercive approach to simultaneously register and segment multi-modal images which share similar spatial structure. Registration is done at the region level to facilitate data fusion while avoiding the need for interpolation. The algorithm performs alternating minimization of an objective function informed by statistical models for pixel values in different modalities. Hypothesis tests are developed to determine whether to refine segmentations by splitting regions. We demonstrate that our approach has significantly better performance than the state-of-the-art registration and segmentation methods on microscopy images.Comment: This work has been accepted to International Conference on Image Processing (ICIP) 201

Simulation of How Jack Pine Budworm (Lepidoptera: Tortricidae) Affects Economic Returns From Jack Pine Timber Production in Michigan

The impact of jack pine budworm on economic returns from jack pine timber production in Lower Michigan and management actions that might be taken to reduce this impact were evaluated with a simulation model. Results indicate that current jack pine rotation ages arc excessive and should be reduced. Insecticide application is not a viable strategy for reducing jack pine budworm impact

Entrepreneurship Everywhere: Across Campus, Across Communities, and Across Borders

This paper introduces the theme of this special issue related to “Entrepreneurship Everywhere: Across Campus, Across Communities, and Across Borders.” We explore three critical points as we set up the accepted articles for the special issue. First, if we are everywhere are we anywhere? Second, we focus on the importance of collaboration. Third, we discuss the importance of strategically planning on how your efforts intervene or integrate into the wider ecosystem. Entrepreneurship is everywhere. A search of the term “entrepreneurship” on Google yields 132 million results. By comparison a search on “strategic management” yields a mere 17.2 million results. Despite the highly unscientific nature of this comparison, the results shine the light on the tremendous interest and growth in entrepreneurship and entrepreneurs. The job creation potential of small businesses and entrepreneurial firms has captured the attention of politicians from across the globe and the ideological spectrum, who frequently hale the benefits of entrepreneurial activity. Citing work by Tornatzky and Rideout (2014), the Kauffman Foundation’s (2015) “State of Entrepreneurship” address indicates that entrepreneurship programs, both curricular and noncurricular, are the fastest-growing programs on college campuses. While many large corporations are villainized, entrepreneurs and small businesses are generally held in high regard and lionized in many instances. Further, interest and growth in the topic of entrepreneurship is unbound by geography or academic discipline. Across many university campuses it is common to find multiple programs and centers dedicated to fostering and growing entrepreneurship. Programs as diverse as engineering, music, pharmacy, agriculture, art, and law are all focusing on helping their students to both engage in entrepreneurial thinking and activity. While the business school remains a key component of the entrepreneurial ecosystem on campuses across the globe, the diversity of programs has grown dramatically. This special issue seeks to highlight this expansive growth by including a diverse set of articles that point to the explosive growth of entrepreneurship and entrepreneurship programing around the world, within our communities and on college campuses. We will briefly preview each of the contributions below, but first we highlight three critical and related questions of the growth of entrepreneurship. First, if entrepreneurship is everywhere, is it truly anywhere? Second, as entrepreneurship continues to be an emphasis across levels of federal, state, and local government and as diverse university entities continue to seek to spark entrepreneurial activities, how is this best managed? Third, how is the entrepreneurial ecosystem affected by the tremendous investment and enhanced focus of universities and government entities in trying to engineer entrepreneurship

Intuitive Biases in Choice Versus Estimation: Implications for the Wisdom of Crowds

Although researchers have documented many instances of crowd wisdom, it is important to know whether some kinds of judgments may lead the crowd astray, whether crowds’ judgments improve with feedback over time, and whether crowds’ judgments can be improved by changing the way judgments are elicited. We investigated these questions in a sports gambling context (predictions against point spreads) believed to elicit crowd wisdom. In a season-long experiment, fans wagered over $20,000 on NFL football predictions. Contrary to the wisdom-of-crowds hypothesis, faulty intuitions led the crowd to predict “favorites” more than “underdogs” against point spreads that disadvantaged favorites, even when bettors knew that the spreads disadvantaged favorites. Moreover, the bias increased over time, a result consistent with attributions for success and failure that rewarded intuitive choosing. However, when the crowd predicted game outcomes by estimating point differentials rather than by predicting against point spreads, its predictions were unbiased and wiser

Hole-mobility-limiting atomic structures in hydrogenated amorphous silicon

Low hole mobility currently limits the efficiency of amorphous silicon photovoltaic devices. We explore three possible phenomena contributing to this low mobility: coordination defects, self-trapping ionization displacement defects, and lattice expansion allowing for hole wave-function delocalization. Through a confluence of experimental and first-principles investigations, we demonstrate the fluidity of the relative prevalence of these defects as film stress and hydrogen content are modified, and that the mobility of a film is governed by an interplay between various defect types

Challenging Situations in Family Centered Rounds: Making the Best out of Worst Case Scenarios

This resource is a workshop intended for both seasoned and novice health care providers who are interested in becoming prepared for challenging scenarios that may be encountered during FCR. Case scenarios of challenging situations relating to discussing sensitive topics, correcting errors, and teaching learners in front of both parents and patients are presented. Tangible opportunities to role model communication skills, efficiency, and teaching skills for trainees are highlighted. The session will conclude with a question and answer session with a multi-specialty panel to share experiences and strategies for addressing the unexpected during FCR. By the end of the workshop, participants will take away concrete strategies that they can share with their home institutions that will enhance the FCR process. AAMC MedEdPORTAL publication ID 9728.
