Charles Oliver Ingamells passed away in April 1994 at age 77. Ingamells received his BA at the University of Western Ontario and his MS at the University of Minnesota. During his later years in his retirement home in Florida he was a faithful representative of a group of well-known world experts in Sampling Theory, such as Pierre M. Gy, Francis F. Pitard, Jan Visman, Paul Switzer at Stanford University and J.C. Engels at the US Geological Survey and the Linus Pauling Institute in Menlo Park, California. His association with Francis F. Pitard during several years at Amax Extractive Research & Development in Colorado has added to a unique combination of different experiences in the field of geochemical analysis. His pioneering work in the field of geological sampling led to collaboration with the above experts.

As a final-year trainee in vascular surgery, I was working at the West London Renal and Transplant Centre for Professor Nadey Hakim and Vassilios Papalois. I am very grateful to both of them for encouraging me to apply for a visiting fellowship to the United States, enabling me to experience some of the benefits of surgical training abroad and to broaden my perspectives in transplantation. I was awarded a visiting fellowship to the University of Minnesota Transplant Center by Professor David Sutherland, head of the division of transplant surgery.

This paper describes three alternative architectural studio teaching models taught by the authors at the University of Minnesota and at Stanford University. The three models attempt to build independent and collaborative capacity in students and to emphasize iterative components of the design process. Collectively, the models reflect the authors’ shared conviction that studio education is quite pliable and available to a wide variety of changes in approach and methods.The three models discussed in this paper are the Harkness model, the Exchanges in the Thick Middle and Shifting Allegiances. The Harkness model was implemented and tested in early undergraduate studios at Stanford University. Exchanges in the Thick Middle and the Shifting Allegiances studios, studio pedagogy based in play frameworks of “movement, change, alternation, succession, association and separations” (Srivastava and Christenson 2018), have been tested at the University of Minnesota and North Dakota State University in both undergraduate and graduate studios. All three models are briefly introduced in this paper, followed by a description of the typical day and a typical review in the studios. The conclusions section briefly outlines the overlaps and differences in the three models.

Refugee resettlement is a complex process relevant to migration medicine. A partnership between the International Organization for Migration, the US Centers for Disease Control and Prevention, and the University of Minnesota addresses medical needs of refugees and serves as a model for improving the continuum of care delivered to refugees.

A new project at the University of Minnesota will provide data extraction and distribution over the Internet of the Integrated Public Use Microdata Series – a database which integrates all existing national samples of the US census from 1850 to 1990 into a consistent format.

On December 2, 2015, two self-radicalized terrorists carried out the deadliest terrorist attack on US soil since the September 11th attacks, which remained the deadliest until the attack in Orlando. President Barack Obama made several statements in the days following the attack, and the way he addresses the nation in a time of crisis is of great significance due to the fragile emotional state of the public. Much can be learned from these statements about the President’s priorities in the wake of an attack. His views about the people who commit these acts of terror, the religion they claim to follow, and securing the country are all very apparent in these public addresses. Among Obama’s top priorities following a terrorist attack are reassuring the public and gaining their trust and support, characterizing the attackers and explaining their motivations, presenting a plan for recovery and prevention, and insisting that the US is not at war with Islam. Evaluating the effectiveness of these statements for gaining support for proposed policies and general approval provides useful insight into the President’s rhetorical strategies. President Obama successfully conveys his thoughts about Islam, terrorism, and mass shootings, but does not effectively gain support for his proposed policy changes. // A final research paper for the course COMM 3676W - Communicating Terrorism at the University of Minnesota – Twin Cities, finalized on December 19, 2016 and presented at the University of St. Thomas Undergraduate Communication Research Conference on a panel titles "Looming War and Terror: Uniting People Through Rhetoric" on March 31, 2017.

Abstract. We present over one year of continuous atmospheric methanol measurements from the University of Minnesota tall tower Trace Gas Observatory (KCMP tall tower; 244 m a.g.l.), and interpret the dataset in terms of constraints on regional methanol sources and seasonality. The seasonal cycle of methanol concentrations observed at the KCMP tall tower is generally similar to that simulated by a global 3-D chemical transport model (GEOS-Chem, driven with MEGANv2.0 biogenic emissions) except the seasonal peak occurs ~1 month earlier in the observations, apparently reflecting a model underestimate of emission rates for younger versus older leaves. Based on a source tracer approach, which we evaluate using GEOS-Chem and with multiple tracers, we estimate that anthropogenic emissions account for approximately 40 % of ambient methanol abundance during winter and 10 % during summer. During daytime in summer, methanol concentrations increase exponentially with temperature, reflecting the temperature sensitivity of the biogenic source, and the observed temperature dependence is statistically consistent with that in the model. Nevertheless, summertime concentrations are underestimated by on average 35 % in the model for this region. The seasonal importance of methanol as a source of formaldehyde (HCHO) and carbon monoxide (CO) is highest in spring through early summer, when biogenic methanol emissions are high but isoprene emissions are still relatively low. During that time observed methanol concentrations account for on average 20 % of the total CO and HCHO production rates as simulated by GEOS-Chem, compared to 12 % later in the summer and 12 % on an annual average basis. The biased seasonality in the model means that the photochemical role for methanol early in the growing season is presently underestimated.
