Health implications of an immigration raid: findings from a Latino community in the midwestern United States.

Immigration raids exemplify the reach of immigration law enforcement into the lives of Latino community members, yet little research characterizes the health effects of these raids. We examined the health implications of an immigration raid that resulted in multiple arrests and deportations and occurred midway through a community survey of a Latino population. We used linear regression following principal axis factoring to examine the influence of raid timing on immigration enforcement stress and self-rated health. We controlled for age, sex, relationship status, years in the county in which the raid occurred, children in the home, and nativity. 325 participants completed the survey before the raid and 151 after. Completing the survey after the raid was associated with higher levels of immigration enforcement stress and lower self-rated health scores. Findings indicate the negative impact of immigration raids on Latino communities. Immigration discussions should include holistic assessments of health.UL1 TR000433 - NCATS NIH HH

Reexamination of Herpetofauna on Mormon Island, Hall County, Nebraska, with Notes on Natural History

The Platte River in central Nebraska, USA, was historically surrounded by mixed grass and tallgrass prairies and wet meadows, but many of those habitats were lost or altered during the last century with unknown effects on animals that reside in them. Researchers first surveyed herpetofauna on part of a large island preserve in the Platte River, Mormon Island, Hall County, Nebraska, in 1980 when the land was protected for conservation. They documented 10 species, including three species of amphibians and seven species of reptiles. We inventoried herpetofauna after 30 years of conservation management on Mormon Island and adjacent Shoemaker Island. We captured four species of amphibians and 11 species of reptiles, including five species not detected in the previous survey. New species documented on the preserve were the Bullfrog (Lithobates catesbeianus), Eastern Racer (Coluber constrictor), Smooth Green Snake (Liochlorophis vernalis), Redbelly Snake (Storeria occipitomaculata), and Lined Snake (Tropidoclonion lineatum). Smooth Green Snakes represent a new county record, and Redbelly Snakes represent the easternmost published distributional limit for this disjunct population in central Nebraska. Documentation of additional snake species likely reflects a more intensive trapping regime and possibly habitat changes since 1980. Presence of Bullfrogs on Mormon Island probably was linked to excavation of a backwater slough that created a site for overwintering tadpoles. Herein we describe the variable life-history characteristics, habitats, and seasonal activity patterns among these 15 species of herpetofauna on the large river islands. We also discuss how restoration activities and hydrologic changes may influence the presence and abundance of herpetofauna in the region. Understanding the occurrence, habitat use, and seasonality of amphibians and reptiles in this topographically unaltered (i.e., unplowed) reach of river will aid in managing the central Platte River ecosystem to protect and maintain its biological integrity for all organisms

Teaching LLCs Through a Problem-Based Approach

Case studies and case simulations can be used to teach LLCs with an eye toward training business lawyers. These tools can be used in the traditional four-credit Business Associations (BA) course to supplement traditional teaching materials with mini-case studies that accent and apply analysis of primary legal sources. Alternatively, case studies and case simulations can be the centerpiece of a specialized course on LLCs. We discuss both approaches in this short essay

Deal Deconstructions, Case Studies, And Case Simulations: Toward Practice Readiness With New Pedagogies In Teaching Business And Transactional Law

In this short commentary, we explore the use of two interrelated pedagogical methods for teaching transactional and business law. The first method is deal deconstruction, which analyzes the set of final deal documents and outcomes. This method is backward-looking, conducting a post-mortem on business transactions and analyzing the parties’ choices memorialized in the agreement against the legal and financial alternatives. The second method involves case studies and simulations, which are commonly seen in business schools. This method is forward-looking, exposing students to the uncertainties and situational contexts of doing deals and deal-related litigation. Together, these complementary methods help students understand the tradeoffs and dynamics of transactions and deal negotiations. They provide pedagogical alternatives to the traditional Langdellian method, which relies heavily on the study of edited appellate opinions. By presenting problems in different packages and from different temporal perspectives, these methods hone analytical, deal structuring, problem-solving, and decision-making skills

Differences in Cottonwood Growth Between a Losing and a Gaining Reach of an Alluvial Floodplain

Interstitial flow of river (hyporheic) water influences algal productivity, benthic assemblages, and locations of fish spawning. However, little is known of the effects of hyporheic flow on the growth of riparian vegetation. By increasing water availability and nutrient delivery, regional upwelling of hyporheic water may increase the growth of terrestrial vegetation. We tested and accepted the hypothesis that cottonwood trees (Populus trichocarpa) in a gaining reach of an alluvial floodplain grow faster than trees in a losing reach by comparing basal areas and ages on an expansive floodplain in western Montana (USA). Trees in the gaining reach had basal areas twice the size of the trees in the losing reach, after correcting for tree age. In addition, the carbon-to-nitrogen ratios in leaves were 16% lower in the gaining reach. Lower cottonwood stem densities, deeper layers of fine sediments, and a higher water table occurred in the gaining compared to the losing reach. Each of these variables was significantly correlated with tree growth and likely interacted to influence the productivity of cottonwoods. We concluded that hydration and fertilization of riparian trees likely is mediated by hyporheic flow

Electronic Field Trips for Science Engagement: The Streaming Science Model

While institutions of higher education work to engage PK-12 youth in STEM (science, technology, engineering, and mathematics) concepts and careers via in-person programming, PK-12 teachers and students face many logistical and access constraints for physically traveling to sites off of school grounds during the school day. Throughout the years, electronic field trips (EFTs) have offered a digital way for schools to engage in meaningful ways with museums, parks, laboratories, and field research sites. In order for EFTs to be effective, they should be cost effective and created collaboratively with teachers, students, subject matter experts, and instructional design and communication professionals. Streaming Science is an online science communication platform that aimed to develop and implement an effective EFT model. Three Streaming Science live interactive EFTs webcasted online were piloted from various locations during 2017-2019 to test wireless internet connections, mobile technologies, STEM content, and impacts on students’ interest, attitudes, and learning. The model proved iPads and mobile applications in the field for web streaming were effective for connecting scientists with school audiences. In this professional development article, authors describe the Streaming Science EFT model, including recommendations for instructional design, the pre-production process, content development, teacher collaboration, student engagement, mobile hardware and software, and assessment

Impact of evaporative pads and cross ventilation on core body temperature and resting time of lactating cows

A trial was conducted to determine the impact of evaporative cooling pads on core body temperature (CBT), time spent lying, and number of lying bouts of Holstein cows housed in cross-ventilated freestall facilities. Despite cool ambient conditions during the trial, cows without evaporative pads tended to have elevated CBT above 102°F for 2.3 more hours per day and elevated CBT above 102.5°F for 0.95 more hours per day than cows with evaporative pads. These trends were evident even though the stocking density of the freestalls was greater in the facility with evaporative pads than in the facility without pads (123 vs. 113%). Lying times and lying bouts did not differ between treatments. Results of this study indicate that CBT tended to be reduced when evaporative pads were used, even under relatively mild ambient conditions.; Dairy Day, 2009, Kansas State University, Manhattan, KS, 2009; Dairy Research, 2009 is known as Dairy Day, 200

Ability of low profile cross-ventilated freestall barns to improve environmental conditions for dairy cattle

Recently, there has been interest in constructing mechanical ventilation with evaporative pads to improve the environmental conditions for cows during periods of heat stress. Low profile cross-ventilated freestalls with evaporative pads (LPCV) have become a popular system. The purpose of this study was to evaluate how well these LPCV systems improve the temperature-humidity index (THI) under different ambient conditions. As ambient humidity increases, ability of the LPCV to reduce THI is decreased. Producers wishing to construct LPCV barns should carefully evaluate the climate in which they want to construct LPCV structures.; Dairy Day, 2007, Kansas State University, Manhattan, KS, 2007; Dairy Research, 2007 is known as Dairy Day, 200
