Defining and Measuring Poverty in Nebraska

Data recently released by the Census Bureau estimate that 47.4 million Americans, or about one-insix, are living in poverty. This latest estimate has drawn criticism from some observers who see it as an attempt to artificially inflate the magnitude of poverty in America. The criticism results from a change in methodology that included not just income (the Whitehouse Office of Management and Budget (OMB) poverty threshold for 2009 is $22,050 a year for a family of four), but also made adjustments, taking into account such things as region, out-of-pocket medical expenses and child care costs, that in total add about seven-million individuals to the poverty population.

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.

Epatite E: ruolo del suino nella trasmissione dell'infezione all'uomo, studio di prevalenza in aree rurali della Bolivia

L’infezione da virus dell’ epatite E (HEV) nei suini e nell’uomo è stata segnalata in diversi Paesi. Nei suini, il virus causa infezioni asintomatiche, mentre nell’uomo è responsabile di epidemie di epatite ad andamento acuto nei Paesi a clima tropicale o subtropicale con condizioni igieniche scadenti, di casi sporadici in quelli sviluppati. HEV è stato isolato anche in diversi animali e l’analisi nucleotidica degli isolati virali di origine animale ha mostrato un elevato grado di omologia con i ceppi di HEV umani isolati nelle stesse aree geografiche, avvalorando l’ipotesi che l'infezione da HEV sia una zoonosi. In America del Sud HEV suino è stato isolato per la prima volta in suini argentini nel 2006, mentre solo dal 1998 esistono dati sull’ infezione da HEV nell’uomo in Bolivia. In questa indagine è stato eseguito uno studio di sieroprevalenza in due comunità rurali boliviane e i risultati sono stati confrontati con quelli dello studio di sieroprevalenza sopra menzionato condotto in altre zone rurali della Bolivia. Inoltre, mediante Nested RT-PCR, è stata verificata la presenza di HEV nella popolazione umana e suina. La sieroprevalenza per anticorpi IgG anti-HEV è risultata pari al 6,2%, molto simile a quella evidenziata nello studio precedente. La prevalenza maggiore (24%) si è osservata nei soggetti di età compresa tra 41 e 50 anni, confermando che l’ infezione da HEV è maggiore fra i giovani-adulti. La ricerca di anticorpi anti HEV di classe IgM eseguita su 52 sieri ha fornito 4 risultati positivi. Il genoma virale è stato identificato in uno dei 22 pool di feci umane e l'esame virologico di 30 campioni individuali fecali e 7 individuali di siero ha fornito rispettivamente risultati positivi in 4/30 e 1/7. La Nested RT-PCR eseguita sui 22 pool di feci suine ha dato esito positivo in 7 pool. L’analisi delle sequenze genomiche di tutti gli amplificati ha consentito di stabilire che gli isolati umani appartenevano allo stesso genotipo III di quelli suini e presentavano con questi una elevata omologia aminoacidica (92%).

Strutture a pareti portanti in C. A. caratterizzate da elevate prestazioni sismiche

Per quanto riguarda le costruzioni in conglomerato cementizio armato gettato in opera, i sistemi strutturali più comunemente utilizzati sono quelli a telaio (con trasmissione di momento flettente), a setti portanti o una combinazione di entrambi. A partire dagli anni ’60, numerosissimi sono stati gli studi relativamente al comportamento sismico di strutture in c.a. a telaio. Lo stesso si può affermare per le costruzioni costituite da pareti miste a telai. In particolare, l’argomento della progettazione sismica di tali tipologie di edifici ha sempre riguardato soprattutto gli edifici alti nei quali, evidentemente, l’impiego delle pareti avveniva allo scopo di limitarne la elevata deformabilità. Il comportamento sismico di strutture realizzate interamente a pareti portanti in c.a. è stato meno studiato negli anni, nonostante si sia osservato che edifici realizzati mediante tali sistemi strutturali abbiano mostrato, in generale, pregevoli risorse di resistenza nei confronti di terremoti anche di elevata intensità. Negli ultimi 10 anni, l’ingegneria sismica si sta incentrando sull’approfondimento delle risorse di tipologie costruttive di cui si è sempre fatto largo uso in passato (tipicamente nei paesi dell’Europa continentale, in America latina, negli USA e anche in Italia), ma delle quali mancavano adeguate conoscenze scientifiche relativamente al loro comportamento in zona sismica. Tali tipologie riguardano sostanzialmente sistemi strutturali interamente costituiti da pareti portanti in c.a. per edifici di modesta altezza, usualmente utilizzati in un’edilizia caratterizzata da ridotti costi di realizzazione (fabbricati per abitazioni civili e/o uffici). Obiettivo “generale” del lavoro di ricerca qui presentato è lo studio del comportamento sismico di strutture realizzate interamente a setti portanti in c.a. e di modesta altezza (edilizia caratterizzata da ridotti costi di realizzazione). In particolare, le pareti che si intendono qui studiare sono caratterizzate da basse percentuali geometriche di armatura e sono realizzate secondo la tecnologia del cassero a perdere. A conoscenza dello scrivente, non sono mai stati realizzati, fino ad oggi, studi sperimentali ed analitici allo scopo di determinare il comportamento sismico di tali sistemi strutturali, mentre è ben noto il loro comportamento statico. In dettaglio, questo lavoro di ricerca ha il duplice scopo di: • ottenere un sistema strutturale caratterizzato da elevate prestazioni sismiche; • mettere a punto strumenti applicativi (congruenti e compatibili con le vigenti normative e dunque immediatamente utilizzabili dai progettisti) per la progettazione sismica dei pannelli portanti in c.a. oggetto del presente studio. Al fine di studiare il comportamento sismico e di individuare gli strumenti pratici per la progettazione, la ricerca è stata organizzata come segue: • identificazione delle caratteristiche delle strutture studiate, mediante lo sviluppo/specializzazione di opportune formulazioni analitiche; • progettazione, supervisione, ed interpretazione di una estesa campagna di prove sperimentali eseguita su pareti portanti in c.a. in vera grandezza, al fine di verificarne l’efficace comportamento sotto carico ciclico; • sviluppo di semplici indicazioni (regole) progettuali relativamente alle strutture a pareti in c.a. studiate, al fine di ottenere le caratteristiche prestazionali desiderate. I risultati delle prove sperimentali hanno mostrato di essere in accordo con le previsioni analitiche, a conferma della validità degli strumenti di predizione del comportamento di tali pannelli. Le elevatissime prestazioni riscontrate sia in termini di resistenza che in termini di duttilità hanno evidenziato come le strutture studiate, così messe a punto, abbiano manifestato un comportamento sismico più che soddisfacente.

Muslime in Ruanda – von Marginalisierung zu Integration /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 74

Zwischen April und Juni 1994 wurden in dem kleinen zentralafrikanischen Land Ruanda ca. 800.000 Menschen ermordet worden. Die Mehrzahl der Opfer waren Tutsi, aber auch viele Hutu verloren ihr Leben. Nahezu jede internationale und nationale Organisation versagte im Angesicht des Ausmaßes der Tragödie. Auch die in Ruanda sehr einflussreiche katholische Kirche konnte oder wollte die Massaker nicht beenden. Einzig die in der ruandischen Geschichte bis zum Genozid immer marginalisierten Muslime verweigerten in der Mehrzahl eine Teilnahme an den Massakern. Warum es zu diesem Verhalten kam, steht als Ausgangsfrage zu Beginn der Untersuchung. Im Folgenden gliedert sich die Arbeit in drei Teile – Geschichte des Islam bis 1994, Verhalten der Muslime im Völkermord von 1994 und die Veränderungen in den zehn Jahren nach dem Genozid. Die Arbeit, welche sich auf die Ergebnisse einer zweimonatigen Feldforschung und einige ältere Arbeiten zum Thema stützt, macht deutlich, dass die Geschichte der ruandischen Muslime bis 1994 durch eine kontinuierliche Marginalisierung gekennzeichnet war. Als nach dem Völkermord das außergewöhnliche Verhalten der ruandischen Muslime langsam deutlich wurde, änderte sich bei vielen Menschen und auch bei offiziellen Stellen auch die Einstellung gegenüber Muslimen.

The Evolution of Media Coverage of Historical Sports Controversies

This thesis will cover sports controversies throughout the 20th Century in the context of the media’s newspaper coverage of the events. The 1919 Black Sox Scandal, the debate over American participation in the 1936 Olympics, and Muhammad Ali’s conversion to the Nation of Islam, standing as a notorious public figure, and conscientious objection to the Vietnam War will represent the three sports controversies. The media’s adherence to cultural norms is clear in all three cases. The consistent devotion to the cultural and racial atmosphere of their respective eras was constant and helped to perpetuate accepted, mainstream cultural attitudes. Cultural and racial norms were followed in the coverage of the three discussed controversies. The anti-Semitism and racially intolerant sentiments in America during great waves of immigration in the early 1900s allowed for journalists to freely vilify Jews as corrupters of baseball and the ballplayers who were rumored to have thrown the 1919 World Series. The white ballplayers were supported in the press, who protected their own and blamed outsiders. Jim Crow and the Americanization movement forced African American and Jewish newspapers to limit their journalistic bias on both sides of the debate over American participation in the 1936 Berlin Olympics. The white, mainstream press was void of bias as the spirit of isolationism in America triumphed over journalist’s leanings in the Olympic debate. The racial tension created by the Civil Rights movement of the 1960s created an atmosphere that allowed mainstream journalists to heap endless criticism on Muhammad Ali as he gained fame. By portraying him as a villain of society as both a religious radical and traitor to America, journalists created a common enemy in the minds of white America. In all three cases, a pattern of journalists expressing the state of cultural and racial norms of the era is present and significant.

Työmies and Pappi: A Critical Look at the Finnish Socialist Federation and the Suomi Synod in Early 20th Century Michigan

At the dawn of the 20th century, the burgeoning influence of the Finnish immigrant socialist-unionist movement collided with the authoritative, conservative nature of the Suomi Synod. While the Synod, headquartered in Hancock, Michigan, was attempting to recreate the Finnish state church in America, the quickly radicalizing immigrant socialist-unionist movement was attempting to convert the masses to a materialist message of class struggle manifested by then current conditions in Michigan’s Copper Country and industrial America. The most persuasive voice of class struggle for immigrant Finns at this time was the Finnish-language newspaper Työmies (The Workingman) published in Hancock. Caustic editorials on religion, critical examinations of Christian orthodoxy in translations of Marx and Kropotkin, and ribald cartoons lampooning members of the Synod clergy and laity all demonstrated the overwrought interactions between Työmies and the Synod. This paper will highlight these tense interactions through analysis of doctrine, ideology, and imagery by delving into the primary historical record to reveal the vast gulf between two of the major institutions in early 20th century Finnish immigrant social life.

Past is Prologue: Montana’s Historic Women’s Movement Re-emerges in the Progressive 1970s -- Dorothy Bradley, Marilyn Wessel & Jane Jelinski “In the Crucible of Change”

One-hundred years ago, in 1914, male voters in Montana (MT) extended suffrage (voting rights) to women six years before the 19th Amendment to the US Constitution was ratified and provided that right to women in all states. The long struggle for women’s suffrage was energized in the progressive era and Jeanette Rankin of Missoula emerged as a leader of the campaign; in 1912 both major MT political party platforms supported women suffrage. In the 1914 election, 41,000 male voters supported woman suffrage while nearly 38,000 opposed it. MT was not only ahead of the curve on women suffrage, but just two years later in 1916 elected Jeanette Rankin as the first woman ever elected to the United States Congress. Rankin became a national leader for women's equality. In her commitment to equality, she opposed US entry into World War I, partially because she said she could not support men being made to go to war if women were not allowed to serve alongside them. During MT’s initial progressive era, women in MT not only pursued equality for themselves (the MT Legislature passed an equal pay act in 1919), but pursued other social improvements, such as temperance/prohibition. Well-known national women leaders such as Carrie Nation and others found a welcome in MT during the period. Women's role in the trade union movement was evidenced in MT by the creation of the Women's Protective Union in Butte, the first union in America dedicated solely to women workers. But Rankin’s defeat following her vote against World War I was used as a way for opponents to advocate a conservative, traditionalist perspective on women's rights in MT. Just as we then entered a period in MT where the “copper collar” was tightened around MT economically and politically by the Anaconda Company and its allies, we also found a different kind of conservative, traditionalist collar tightened around the necks of MT women. The recognition of women's role during World War II, represented by “Rosie the Riveter,” made it more difficult for that conservative, traditionalist approach to be forever maintained. In addition, women's role in MT agriculture – family farms and ranches -- spoke strongly to the concept of equality, as farm wives were clearly active partners in the agricultural enterprises. But rural MT was, by and large, the bastion of conservative values relative to the position of women in society. As the period of “In the Crucible of Change” began, the 1965 MT Legislature included only three women. In 1967 and 1969 only one woman legislator served. In 1971 the number went up to two, including one of our guests, Dorothy Bradley. It was only after the Constitutional Convention, which featured 19 women delegates, that the barrier was broken. The 1973 Legislature saw 9 women elected. The 1975 and 1977 sessions had 14 women legislators; 15 were elected for the 1979 session. At that time progressive women and men in the Legislature helped implement the equality provisions of the new MT Constitution, ratified the federal Equal Rights Amendment in 1974, and held back national and local conservatives forces which sought in later Legislatures to repeal that ratification. As with the national movement at the time, MT women sought and often succeeded in adopting legal mechanisms that protected women’s equality, while full equality in the external world remained (and remains) a treasured objective. The story of the re-emergence of Montana’s women’s movement in the 1970s is discussed in this chapter by three very successful and prominent women who were directly involved in the effort: Dorothy Bradley, Marilyn Wessel, and Jane Jelinski. Their recollections of the political, sociological and cultural path Montana women pursued in the 1970s and the challenges and opposition they faced provide an insider’s perspective of the battle for equality for women under the Big Sky “In the Crucible of Change.” Dorothy Bradley grew up in Bozeman, Montana; received her Bachelor of Arts Phi Beta Kappa from Colorado College, Colorado Springs, in 1969 with a Distinction in Anthropology; and her Juris Doctor from American University in Washington, D.C., in 1983. In 1970, at the age of 22, following the first Earth Day and running on an environmental platform, Ms. Bradley won a seat in the 1971 Montana House of Representatives where she served as the youngest member and only woman. Bradley established a record of achievement on environmental & progressive legislation for four terms, before giving up the seat to run a strong second to Pat Williams for the Democratic nomination for an open seat in Montana’s Western Congressional District. After becoming an attorney and an expert on water law, she returned to the Legislature for 4 more terms in the mid-to-late 1980s. Serving a total of eight terms, Dorothy was known for her leadership on natural resources, tax reform, economic development, and other difficult issues during which time she gained recognition for her consensus-building approach. Campaigning by riding her horse across the state, Dorothy was the Democratic nominee for Governor in 1992, losing the race by less than a percentage point. In 1993 she briefly taught at a small rural school next to the Northern Cheyenne Indian Reservation. She was then hired as the Director of the Montana University System Water Center, an education and research arm of Montana State University. From 2000 - 2008 she served as the first Gallatin County Court Administrator with the task of collaboratively redesigning the criminal justice system. She currently serves on One Montana’s Board, is a National Advisor for the American Prairie Foundation, and is on NorthWestern Energy’s Board of Directors. Dorothy was recognized with an Honorary Doctorate from her alma mater, Colorado College, was named Business Woman of the Year by the Bozeman Chamber of Commerce and MSU Alumni Association, and was Montana Business and Professional Women’s Montana Woman of Achievement. Marilyn Wessel was born in Iowa, lived and worked in Los Angeles, California, and Washington, D.C. before moving to Bozeman in 1972. She has an undergraduate degree in journalism from Iowa State University, graduate degree in public administration from Montana State University, certification from the Harvard University Institute for Education Management, and served a senior internship with the U.S. Congress, Montana delegation. In Montana Marilyn has served in a number of professional positions, including part-time editor for the Montana Cooperative Extension Service, News Director for KBMN Radio, Special Assistant to the President and Director of Communications at Montana State University, Director of University Relations at Montana State University and Dean and Director of the Museum of the Rockies at MSU. Marilyn retired from MSU as Dean Emeritus in 2003. Her past Board Service includes Montana State Merit System Council, Montana Ambassadors, Vigilante Theater Company, Montana State Commission on Practice, Museum of the Rockies, Helena Branch of the Ninth District Federal Reserve Bank, Burton K. Wheeler Center for Public Policy, Bozeman Chamber of Commerce, and Friends of KUSM Public Television. Marilyn’s past publications and productions include several articles on communications and public administration issues as well as research, script preparation and presentation of several radio documentaries and several public television programs. She is co-author of one book, 4-H An American Idea: A History of 4-H. Marilyn’s other past volunteer activities and organizations include Business and Professional Women, Women's Political Caucus, League of Women Voters, and numerous political campaigns. She is currently engaged professionally in museum-related consulting and part-time teaching at Montana State University as well as serving on the Editorial Board of the Bozeman Daily Chronicle and a member of Pilgrim Congregational Church and Family Promise. Marilyn and her husband Tom, a retired MSU professor, live in Bozeman. She enjoys time with her children and grandchildren, hiking, golf, Italian studies, cooking, gardening and travel. Jane Jelinski is a Wisconsin native, with a BA from Fontbonne College in St. Louis, MO who taught fifth and seventh grades prior to moving to Bozeman in 1973. A stay-at-home mom with a five year old daughter and an infant son, she was promptly recruited by the Gallatin Women’s Political Caucus to conduct a study of Sex-Role Stereotyping in K Through 6 Reading Text Books in the Bozeman School District. Sociologist Dr. Louise Hale designed the study and did the statistical analysis and Jane read all the texts, entered the data and wrote the report. It was widely disseminated across Montana and received attention of the press. Her next venture into community activism was to lead the successful effort to downzone her neighborhood which was under threat of encroaching business development. Today the neighborhood enjoys the protections of a Historic Preservation District. During this time she earned her MPA from Montana State University. Subsequently Jane founded the Gallatin Advocacy Program for Developmentally Disabled Adults in 1978 and served as its Executive Director until her appointment to the Gallatin County Commission in 1984, a controversial appointment which she chronicled in the Fall issue of the Gallatin History Museum Quarterly. Copies of the issue can be ordered through: http://gallatinhistorymuseum.org/the-museum-bookstore/shop/. Jane was re-elected three times as County Commissioner, serving fourteen years. She was active in the Montana Association of Counties (MACO) and was elected its President in 1994. She was also active in the National Association of Counties, serving on numerous policy committees. In 1998 Jane resigned from the County Commission 6 months before the end of her final term to accept the position of Assistant Director of MACO, from where she lobbied for counties, provided training and research for county officials, and published a monthly newsletter. In 2001 she became Director of the MSU Local Government Center where she continued to provide training and research for county and municipal officials across MT. There she initiated the Montana Mayors Academy in partnership with MMIA. She taught State and Local Government, Montana Politics and Public Administration in the MSU Political Science Department before retiring in 2008. Jane has been married to Jack for 46 years, has two grown children and three grandchildren.
