Lincoln Downtown Rotary Club

Good afternoon, and thank you for inviting me to be here with you today. One of the things I'm enjoying most in my new position as University of Nebraska Vice President of Agriculture and Natural Resources and Harlan Vice Chancellor of the Institute of Agriculture and Natural Resources is meeting the people who live in this state, in urban and rural areas, from Scottsbluff to Omaha, from Lincoln to Curtis, and at any number of towns - north, south, east, west - in between.

University of Nebraska-Lincoln Extension Fall Conference

First off, thank you. Thank you for the work you do each day on behalf of the University and for Nebraska. Thank you for the expertise and the passion you bring to your work, for the belief you have in it, and for the dedication you show.

A Qualitative Analysis of Youth Feedback of Nutrition School Enrichment Kits in Lincoln, NE

A Qualitative Analysis of Youth Feedback of Nutrition School Enrichment Kits in Lincoln, NE Richard A. Losey, M.S. University of Nebraska, 2010 Advisor: Wanda M. Koszewski The qualitative analysis of the responses given by students participating in classrooms that used the Nutrition Education Program‟s (NEP) school enrichment kits was the primary focus of this research. Data was collected from the participants in written form. Three major themes appeared during analysis of the data, healthy eating habits, cleanliness and change. The theme of healthy eating habits is comprised of the following sub-themes: breakfast, nutrients, label reading, Food Guide Pyramid/MyPyramid and healthy snacks. Cleanliness is comprised of hand washing and food safety sub-themes. The change theme is made up of change in healthy eating habits, change in cleanliness and change in both healthy eating habits and cleanliness. The data suggests that participating students have made or intend to make changes regarding healthy eating habits and cleanliness, which is the goal of nutrition education. The students‟ responses indicate that the NEP school enrichment kits are effective in increasing the knowledge of students and promoting healthy lifestyle changes.

Water Quality Variability in a Bioswell and Concrete Drainage Pipe, Southwest Lincoln, Nebraska

Abstract The goal of this project is to evaluate the effectiveness of bioswells in protecting water quality from urban runoff. The hypothesis tested in this project is that water in bioswells improves water quality. Water quality in both a bioswell and an underground concrete lined ditch, both containing ground and surface water, were tested for certain water quality parameters. These parameters consisted of: Dissolved Oxygen, pH, water temperature, weather temperature, Total Dissolved Solids, Specific Conductivity, Alkalinity, Total Dissolved Carbon, Chemical Oxygen Demand, and depth and width of the sampling site. An additional contaminant that was looked at was motor oil. This was measured by comparing Total Organic Carbon with Chemical Oxygen Demand. A variety of different methods to measure the water quality parameters were utilized. The concrete site had more stable readings, but much higher water temperatures. However, the bioswell water is mainly from surface water runoff, and the underground concrete lined pipe is from underground water, so the two cannot be directly compared. The bioswell had high readings, especially pertaining to Oxygen Demand, Total Organic Carbon, and Specific Conductivity in early test dates. But, these readings improved as they were filtered though the bioswell. As plant activity increased and the weather began to warm up there were more stable readings. It is concluded that bioswells are an effective way to reduce problems associated with urban runoff pertaining to certain water quality parameters.

Distribution of Rain Gardens in Lincoln Nebraska: Are Rain Gardens more Likely to be Built Near Bodies of Water

Abstract Rain gardens are an important tool in reducing the amount of stormwater runoff and accompanying pollutants from entering the city’s streams and lakes, and reducing their water quality. This thesis project analyzed the number of rain gardens installed through the City of Lincoln Nebraska Watershed Management’s Rain Garden Water Quality Project in distance intervals of one-eighth mile from streams and lakes. This data shows the distribution of these rain gardens in relation to streams and lakes and attempts to determine if proximity to streams and lakes is a factor in homeowners installing rain gardens. ArcGIS was used to create a map with layers to determine the number of houses with rain gardens in 1/8 mile distance increments from the city’s streams and lakes and their distances from a stream or lake. The total area, number of house parcels, and the type and location of each parcel type were also determined for comparison between the distance interval increments. The study revealed that fifty-eight percent of rain gardens were installed within a quarter mile of a stream or lake (an area covering 60% of the city and including 58.5% of the city’s house parcels), and that eighty percent of rain gardens were installed within three-eighth mile of streams or lakes (an area covering 75% of the city and 78.5% of the city’s house parcels). All parcels in the city are within 1 mile of a stream or lake. Alone the number of project houses per distance intervals suggested that proximity to a stream or lake was a factor in people’s decisions to install rain gardens. However, when compared to the number of house parcels available, proximity disappears as a factor in project participation.

The History of the German-Russian Colony in Lincoln

Standing at the corner of Tenth and O streets in the city of Lincoln, Nebraska, any week-day morning between 7:30 and 8 o'clock, you may see pass by you from ten to twenty women with little black woolen shawls on their heads. Ask any citizen who they are, and ninety-nine times in one hundred he will tell you they are "Russians" who live down on the bottoms, that they are going out into the offices and homes to wash and scrub and clean house, and that their husbands are street laborers or work for the railroad. He may then grow confidential and tell you that he "has no use for these people", that "they are only half human", and that he "would just as soon see the Chinese come here as those people". As a matter of fact the greater part of his information is incorrect, partly through race prejudice but chiefly through ignorance of their history. These people, of whom there are about 4,000 in the city (Including "beet fielders"), are Germans, not Russians: they are Teutons, not Slavs; they are Lutheran and Reformed, not Greek Catholics. To be sure they and their ancestors lived in Russia for over one hundred years and they came here directly from the realm of the Czar whoso bona fide citizens they were—but they never spoke the Russian language, never embraced the Greek religion, never intermarried with the Russians, and many of their children never saw a Russian until they left their native village for the new home in America. They despise being called "Russians" just as an Italian resents "Dago"; a Jew, "Sheeny"; and a German, "Dutchman". Ask them where they came from and most of the children and not a few of the grown people will say, "Germany". If you pursue your questioning as to what part of Germany, they will tell you "Saratov" or "Samara" - two governments in the eastern part of Russia on the lower course of the Volga river. The misconceptions concerning the desirability of these German-Russians as citizens arise from their unprogressiveness as compared with those Germans who come to us directly from the mother country. During their century's sojourn in Russia they have been out of the main current of civilization, a mere eddy in the stream of progress. They present a concrete example of arrested development, The characteristics which differentiate them from other Germans are not due to an inherent lack of capacity but to different environment. Notwithstanding this, the German- Russians have some admirable qualities. They bring us large stores of physical energy and an almost unlimited capacity for work. The majority of them are literate although the amount of their education is limited. They are thrifty and independent, almost never applying for public aid. They are law abiding, their chief offenses being those which are traceable to their communal life in Russia. They are extremely religious, all their social as well as spiritual life being bound up in the church which they support right royally. To be sure, the saloon gets their vote (the prohibition vote among them is increasing); but "was not the first miracle that Christ performed the turning of water into wine? If they would shut up the shows (theaters), they wouldn't need to shut up the saloons". The object of this paper is to give the historical setting in which the German-Russians have lived as one means to a better understanding and appreciation of them by our own citizens.

IMMIGRATION, THE AMERICAN WEST, AND THE TWENTIETH CENTURY: GERMAN FROM RUSSIA, OMAHA INDIAN, AND VIETNAMESE-URBAN VILLAGERS IN LINCOLN, NEBRASKA

The North American West is a culturally and geographically diverse region that has long been a beacon for successive waves of human immigration and migration. A case in point, the population of Lincoln, Nebraska -- a capital city on the eastern cusp of the Great Plains -- was augmented during the twentieth century by significant influxes of Germans from Russia, Omaha Indians, and Vietnamese. Arriving in clusters beginning in 1876, 1941, and 1975 respectively, these newcomers were generally set in motion by dismal economic, social, or political situations in their sending nations. Seeking better lives, they entered a mainstream milieu dominated by native-born Americans -- most part of a lateral migration from Iowa, Illinois, and Pennsylvania -- who only established their local community in 1867. While this mainstream welcomed their labor, it often eschewed the behaviors and cultural practices ethnic peoples brought with them. Aware but not overly concerned about these prejudices, all three groups constructed or organized distinct urban villages. The physical forms of these enclaves ranged from homogeneous neighborhoods to tight assemblies of relatives, but each suited a shared preference for living among kinspeople. These urban villages also served as stable anchors for unique peoples who were intent on maintaining aspects of their imported cultural identities. Never willing to assimilate to mainstream norms, urban villagers began adapting to their new milieus. While ethnic identity constructions in Lincoln proved remarkably enduring, they were also amazingly flexible. In fact, each subject group constantly negotiated their identities in response to interactions among particular, cosmopolitan, and transnational forces. Particularism refers largely to the beliefs, behaviors, and organizational patterns urban villagers imported from their old milieus. Cosmopolitan influences emanated from outside the ethnic groups and were dictated largely but not exclusively by the mainstream. Transnationalism is best defined as persistent, intense contact across international boundaries. These influences were important as the particularism of dispersed peoples was often reinforced by contact with sending cultures. Adviser: John. R. Wunder

United Way and University partnerships in community-wide human services planning and plan implementation: The case of Lincoln/Lancaster County, Nebraska.

Given the similar interests of United Way organizations and universities in planning, implementation, and evaluation of human services, the two social institutions could be extensively and effectively partnering with one another. However, there is little documentation that such cooperative efforts are taking place. This article describes one such collaboration in Lincoln, Nebraska. The purpose of the article is to show the potential of such collaboration to improve community-wide coordination and outcomes by following the principles of a community-engagement model, to generate more effective use of evaluative tools that can assist in developing evidence-based practices in community planning, and to connect areas of study within the university to United Way efforts.

Taxonomic and distributional notes on Telebasis Selys, 1865, with a redescription of T. pallida Machado, 2010, and an evaluation of the T. racenisi Bick & Bick, 1995 "complex" of species (Odonata, Coenagrionidae)

A full checklist of the species of Telebasis Selys, 1865, housed in the Brazilian collections Colecao Entomologica Prof. Jose Alfredo Pinheiro Dutra, Departamento de Zoologia, Instituto de Biologia, Universidade Federal do Rio do Janeiro (DZRJ), and Museu de Zoologia, Universidade de Sao Paulo (MZSP) is presented. A total of 325 specimens representing 19 species were studied. Ten new records for Brazilian States were found for T. carmesina Calvert, 1909 (Rio de Janeiro and Rio Grande do Sul), T. corallina (Selys, 1876) (Pernambuco), T. demarara (Williamson, 1917) (Maranhao), T. filiola (Perty, 1834) (Paraiba and Santa Catarina), T. gigantea Daigle, 2002 (Sao Paulo), T. inalata (Calvert, 1961) (Mato Grosso do Sul), T. pallida Machado, 2010 (Goias) and T. obsoleta (Selys, 1876) (Mato Grosso do Sul), as well as a new record of T. carminita Calvert, 1909 for Suriname. Telebasis pallida Machado, 2010 is redescribed and diagnosed based on 14 males collected near the type locality, and its genital ligula is described and illustrated for the first time. Furthermore, the status of the three species of the Telebasis racenisi Bick & Bick, 1995 complex is evaluated. Of these, Telebasis pareci Machado, 2010 syn. n. is proposed as junior subjective synonym of Telebasis lenkoi Machado, 2010, and a possible synonymy among the three species is discussed under T. racenisi.

Embriaguez y hacienda pública en Guatemala, 1840-1865: entre la moral decimonónica y los ingresos fiscales

[ES] En los años 1840-1865, el abordaje gubernamental del consumo de bebidas embriagantes transitó desde una perspectiva en que predominaba la visión de la moral pública, escandalizada por los excesos en la embriaguez, hacia otra en la que se impuso la necesidad de maximizar los ingresos fiscales derivados de la fabricación y venta de aguardiente y chicha. Este giro tiene como telón de fondo el tránsito del monopolio estatal de ambas bebidas al ámbito privado y la defensa que los pueblos de indios hicieron de su consumo, en un momento de transición social y económica hacia el Estado agroexportador cafetalero.

Genetic variability and differentiation in the Mediterranean endemic starry ray Raja asterias (Delaroche, 1809)

The present study deal with the population structure and connectivity of the Mediterranean endemic starry ray Raja asterias (Delaroche, 1809) in the Western and Eastern Mediterranean basin. A panel of eight microsatellite loci which cross-amplify in Rajidae (El Nagar, 2010) was used to assess population connectivity and structure. Those aims were investigated by analyzing the genetic variation of 9 population sample for a total of 185 individuals collected during past scientific surveys (MEDITS, GRUND), commercial trawling and also directly at fish markets. The purpose of this thesis is to estimate the genetic divergence occurring between the Mediterranean populations and, in particular, to assess the presence of any barrier (geographic, hydrogeological and biological) to gene flow for this species. Different statistical approaches were performed to reach this aim evaluating both the genetic diversity (nucleotide diversity, allelic richness, observed and expected heterozygosity and Hardy-Weinberg equilibrium test) and the population differentiation patterns (pairwise Fst estimated and population structure analysis). The results obtained from the analysis of the microsatellite dataset suggest a geographic and genetic separation between the starry ray populations of the Mediterranean basin into three or four distinct groups: Western and Eastern Mediterranean basins and Sicilian coast always clustering as an independent group and Algeria which could be or not considered another separate group. The data were discussed from both an evolutionary and a conservation point of view and in relation to previous results obtained by the analysis of mitochondrial marker. A comparison with other Mediterranean demersal skate species was performed in order to better contextualise our results. Finally, our results could offer useful information to protect vulnerable species as R. asterias and developing effective conservation plans in the Mediterranean.

Max Abraham's and Tullio Levi-Civita's approach to Einstein Theory of Relativity

This work deals with the theory of Relativity and its diffusion in Italy in the first decades of the XX century. Not many scientists belonging to Italian universities were active in understanding Relativity, but two of them, Max Abraham and Tullio Levi-Civita left a deep mark. Max Abraham engaged a substantial debate against Einstein between 1912 and 1914 about electromagnetic and gravitation aspects of the theories. Levi-Civita played a fundamental role in giving Einstein the correct mathematical instruments for the General Relativity formulation since 1915. This work, which doesn't have the aim of a mere historical chronicle of the events, wants to highlight two particular perspectives: on one hand, the importance of Abraham-Einstein debate in order to clarify the basis of Special Relativity, to observe the rigorous logical structure resulting from a fragmentary reasoning sequence and to understand Einstein's thinking; on the other hand, the originality of Levi-Civita's approach, quite different from the Einstein's one, characterized by the introduction of a method typical of General Relativity even to Special Relativity and the attempt to hide the two Einstein Special Relativity postulates.

Host race formation in Hyalesthes obsoletus (Signoret 1865)

Die Winden-Glasflügelzikade Hyalesthes obsoletus (Cixiidae, Glasflügelzikaden) nutzte in Deutschland ursprünglich die Ackerwinde Convolvulus arvensis als Wirtspflanze, allerdings nahm in den letzten zwei Dekaden die Abundanz auf der Großen Brennnessel Urtica dioica stark zu, zusammen mit der Inzidenz der Schwarzholzkrankheit Bois noir auf Weinreben. Bois noir wird durch ein Phytoplasma verursacht, das durch H. obsoletus von C. arvensis und U. dioica auf Weinreben übertragen wird. Es stellte sich daher die Frage, ob H. obsoletus Wirtsrassen entwickelt hat, die möglicherweise die Bois noir-Epidemiologie beeinflussen. In der vorliegenden Studie wurden folgende Fragestellungen bearbeitet: rn(1) Gibt es in Deutschland und Europa genetisch unterscheidbare Wirtsrassen von H. obsoletus auf den beiden Wirtspflanzen C. arvensis und U. dioica? Es wurden sieben Mikrosatellitenmarker entwickelt und etabliert, um H. obsoletus Populationen aus Deutschland und Europa genetisch zu analysieren. Es zeigte sich eine deutliche Differenzierung zwischen Populationen von beiden Wirtspflanzen in Deutschland, jedoch nicht in den historischen Ursprungsgebieten der deutschen Populationen, in der Schweiz, Italien oder Slovenien.rn(2) Wo sind die deutschen Wirtsrassen von H. obsoletus entstanden? Eine Einwanderung von südlichen, bereits an U. dioica angepassten Individuen stand einer lokalen Wirtsrassenevolution gegenüber. Die engere genetische Verwandtschaft der deutschen Population auf U. dioica zu denen auf C. arvensis, im Vergleich zu den übrigen Populationen auf U. dioica, impliziert einen lokalen Prozess im nördlichen Verbreitungsgebiet. Eine Immigration südlicher Tiere scheint nicht zur Diversifizierung beigetragen zu haben, führte aber möglicherweise einen U. dioica-spezifischen Phytoplasma-Stamm ein. Durch Wirtsrassenevolution entwickelten sich spezifische, vektorbasierte epidemiologische Kreisläufe der Schwarzholzkrankheit Bois noir. rn(3) Welche Präferenzen zeigen die beiden Wirtsrassen von H. obsoletus für die Wirtspflanzen C. arvensis und U. dioica und unterscheiden sich diese? Die Präferenz von H. obsoletus aus beiden deutschen Wirtsrassen in Bezug auf den Geruch der Wirtspflanzen wurde in einem Y-Olfaktometer untersucht, zusätzlich wurden beide Pflanzen direkt zur Wahl gestellt. Bei beiden Untersuchungen zeigte die Population von C. arvensis eine signifikante Präferenz für ihre native Wirtspflanze. Die Population von U. dioica wies dagegen keine Präferenz für den Geruch einer Wirtspflanze auf, bevorzugte im direkten Test jedoch signifikant ihre native Wirtspflanze. Dies weist darauf hin, dass die Anpassung an den „neuen“ Wirt noch nicht vollständig ist.rn
