<p>The Norwegian Evangelical-Lutheran Church in America decided in 1861 to build their first college close to the western frontier of The Upper Midwest. The site chosen was a bluff above Upper Iowa River, highly visible from Decorah, a small town founded only 12 years earlier, few years after the first settlers arrived. The college building became a relatively vast structure erected between 1862 and 1865, completed to its originally planned symmetrical composition in 1874. The building style and its composition were common among American colleges and universities further east in the US. It is also demonstrated how the Luther College building façade in composition and detailing shows clear influences from a specific German building. This particular building has been designated as especially typical of the German <em>Rundbogenstil</em> (<em>S</em>tyle of the Rounded Arch) with its great mix of various stylistic elements.</p><p>The architect was known as C. H. Griese from Cleveland, Ohio. He is identified as Charles Henry Griese (1821–1909), who immigrated from Germany about 1850 and was known as a mason and contractor, from now on also as an architect. In 1869, Griese also designed the three Norwegian Lutheran churches of Washington Prairie, Stavanger and Glenwood in rural Decorah. They represented a Neo Gothic style which was new to the area, and had an evident architectural character contrasting the more ordinary vernacular churches in the area. They signify a change of style and, like the college building, they demonstrate architectural ambitions new to these Norwegians, giving insight also into the general architectural and vernacular development in the area.</p>

We investigated the relationship between young athletes' perception of their leaders' coaching behavior and the athletes' level of social responsibility. Participants were 204 high school athletes from the Midwest region in the US. Hierarchical regression analysis results showed that there was a positive relationship between the athletes' social responsibility and the coaches' democratic behavior, and a negative relationship between social responsibility and coaches' autocratic behavior. These results indicate that the athletes who perceived their coaches as behaving more democratically and less autocratically had a higher level of social responsibility than the others had. Our findings signify the importance of using types of coaching behavior that enhance student athletes' social responsibility.

Nutrient losses and soil erosion after soybean (Glycine max (L.) Merr.) harvest are common in the US Upper Midwest. Cover crops need to provide adequate growth and cover to prevent soil degradation throughout the winter and early spring months. The objective of this study was to determine the establishment of intersown cover crops and their impacts on a soybean-wheat rotation. Four cover crops—winter camelina (Camelina sativa (L.) Crantz), winter pea (Pisum sativum ssp. arvense (L.) Poir), winter rye (Secale cereale L.), and radish (Raphanus sativus L.)—were directly sown at the R4 and R6 stages of soybean at two locations, Prosper and Fargo, ND in 2016–2017. Cover crops above ground biomass in the fall ranged from 0.4 to 3.0 Mg ha−1 and N accumulation ranged from 28.7 to 73.2 kg ha−1. Winter camelina and winter rye reduced subsequent spring wheat yield compared with the no cover crop treatment. Fall soil residual NO3-N levels were lowest where cover crops were sown compared with the check. Spring NO3-N levels were lowest in winter camelina and winter rye compared with all the other cover crops and the check. Results indicated intersowing cover crops have no impact on soybean yield, and show potential to mitigate soil nitrate losses in areas that grow soybean as a cash crop.

Aedes albopictus is a competent vector of several arboviruses that has spread throughout the United States over the last three decades after it was initially detected in Texas in 1985. With the emergence of Zika virus in the Americas in 2015-2016 and an increased need to better understand the current distributions of Ae. albopictus in the US, we initiated surveillance efforts to determine the abundance of invasive Aedes species in Iowa. Here, we describe the resulting surveillance efforts from 2016-2020 in which we detect stable and persistent populations of Aedes albopictus in three Iowa counties. Based on temporal patterns in abundance and genetic analysis of mitochondrial DNA haplotypes between years, our data support that populations of Ae. albopictus are overwintering and have likely become established in the state. In addition, the localization of Ae. albopictus predominantly in areas of urbanization and noticeable absence in rural areas suggests that these ecological factors may represent potential barriers to their further spread and contribute to overwintering success. Together, these data document the establishment of Ae. albopictus in Iowa and their expansion into the Upper Midwest, where freezing winter temperatures were previously believed to limit their spread. With increasing globalization, urbanization, and rising temperatures associated with global warming, the range of invasive arthropod vectors, such as Ae. albopictus, is expected to only further expand, creating increased risks for vector-borne disease.

The current state of the COVID-19 pandemic in the United States is dire, with circumstances in the Upper Midwest particularly grim. In contrast, multiple countries around the world have shown that temporary changes in human behavior and consistent precautions, such as effective testing, contact tracing, and isolation, can slow transmission of COVID-19, allowing local economies to remain open and societal activities to approach normalcy as of today. These include island countries such as New Zealand, Taiwan, Iceland and Australia, and continental countries such as Norway, Uruguay, Thailand, Finland, and South Korea. These successes demonstrate that coordinated action to change behavior can control the pandemic. In this report, we evaluate how the human behaviors that have been shown to inhibit the spread of COVID-19 have evolved across the US since April, 2020.Our report is based on surveys that the COVID States Project has been conducting approximately every month since April in all 50 US states plus the District of Columbia. We address four primary questions:1) What are the national trends in social distancing behaviors and mask wearing since April?2) What are the trends among particular population subsets?3) What are the trends across individual states plus DC?4) What is the relationship, at the state level, between social distancing behaviors and mask wearing with the current prevalence of COVID-19?

A cache of charred, domesticated chenopod (Chenopodium berlandierisubsp.jonesianum) seeds is reported from the Early Woodland (930–915 cal BC) Tutela Heights site (AgHb-446) in Brantford, Ontario, Canada. This is the northernmost report of the crop, approximately 800 km northeast of Kentucky where the previous northernmost occurrences contemporary with Tutela Heights are reported. The Tutela Heights chenopod dates to about 1,500 years before the earliest maize is reported in Ontario and is the earliest Eastern Agricultural Complex crop in Canada. The chenopod may represent a crop that was not grown locally. In this scenario, the crop was strictly an exchange item that was circulating in an interregional exchange system that extended south to the US Midwest region and east to the Maritime provinces. Another possibility, although less likely given our current understanding of Early Woodland plant use in Ontario, is that chenopod was introduced to Southern Ontario in this exchange network and subsequently became a crop in a low-level food producing economy during the Ontario Early Woodland. However, no ecological indicators of cultivation have been found at Tutela Heights, and continuity of domesticated chenopod utilization from the Early Woodland period in the province has not yet been documented.
