Feeding Ecology Of Arctic-Nesting Sandpipers During Spring Migration Through The Prairie Pothole Region, Jan Eldridge, Gary Krapu, Douglas Johnson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We evaluated food habits of 4 species of spring-migrant calidrid sandpipers in the Prairie Pothole Region (PPR) of North Dakota. Sandpipers foraged in several wetland classes and fed primarily on aquatic dipterans, mostly larvae, and the midge family Chironomidae was the primary food eaten. Larger sandpiper species foraged in deeper water and took larger larvae than did smaller sandpipers. The diverse wetland habitats that migrant shorebirds use in the PPR suggest a landscape-level approach be applied to wetland conservation efforts. We recommend that managers use livestock grazing and other tools, where applicable, to keep shallow, freshwater wetlands from becoming choked …

Body Size And Predatory Performance In Wolves: Is Bigger Better?, Daniel R. Macnulty, Douglas W. Smith, L. David Mech, Lynn E. Eberly

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Summary

1. Large body size hinders locomotor performance in ways that may lead to trade-offs in predator foraging ability that limit the net predatory benefit of larger size. For example, size-related improvements in handling prey may come at the expense of pursuing prey and thus negate any enhancement in overall predatory performance due to increasing size.

2. This hypothesis was tested with longitudinal data from repeated observations of 94 individually known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park, USA. Wolf size was estimated from an individually based sex-specific growth model derived from …

Wolf Use Of Summer Territory In Northeastern Minnesota, Dominic J. Demma, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Movements of wolves (Canis lupus) during summer 2003 and 2004 in the Superior National Forest were based around homesites but included extensive use of territories. Away from homesites, wolves used different areas daily, exhibiting rotational use. Mean daily range overlap was 22% (SE = 0.02) and that of breeding wolves was significantly greater than for nonbreeders (x = 25% and 16%, respectively). Rotational use may improve hunting success. Managers seeking to remove entire packs must maintain control long enough to ensure that all pack members are targeted.

Vulnerability Of Rehabilitated Agricultural Production Systems To Invasion By Nontarget Plant Species, Sara G. Baer, David M. Engle, Johannes M. H. Knops, Kenneth A. Langeland, Bruce D. Maxwell, Fabian D. Menalled, Amy J. Symstad

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Vast areas of arable land have been retired from crop production and ‘‘rehabilitated’’ to improved system states through landowner incentive programs in the United States (e.g., Conservation and Wetland Reserve Programs), as well as Europe (i.e., Agri-Environment Schemes). Our review of studies conducted on invasion of rehabilitated agricultural production systems by nontarget species elucidates several factors that may increase the vulnerability of these systems to invasion. These systems often exist in highly fragmented and agriculturally dominated landscapes, where propagule sources of target species for colonization may be limited, and are established under conditions where legacies of past disturbance persist and …

Farmers And Nature Conservation: What Is Known About Attitudes, Context Factors And Actions Affecting Conservation?, Johan Ahnström, Jenny Höckert, Hanna L. Bergea, Charles A. Francis, Peter Skelton, Lars Hallgren

Department of Agronomy and Horticulture: Faculty Publications

Farmers’ attitudes towards viability of specific conservation practices or actions strongly impact their decisions on adoption and change. This review of ‘attitude’ information reveals a wide range of perceptions about what conservation means and what the impacts of adoption will mean in economic and environmental terms. Farmers operate in a tight financial situation, and in parts of the world they are highly dependent on government subsidies, and cannot afford to risk losing that support. Use of conservation practices is most effective when these are understood in the context of the individual farm, and decisions are rooted in land and resource …

Promoting Consumerism In West Germany During The Cold War: An Agency Perspective, Frauke Hachtmann

College of Journalism and Mass Communications: Faculty Publications

This historical study attempts to explore how advertising, from the perspective of the J. Walter Thompson (JWT) Agency, contributed to the development of consumerism in West Germany during the Cold War (roughly the early 1950s until the late 1980s). The article describes how West Germany rebuilt its economy and eventually developed into the largest exporting country in the world. It also illustrates how advertising as an institution contributed to a functioning consumer society and chronicles the agency’s development in the U.S. and expansion to Germany. Finally, it explores the agency’s insights into consumer behavior in West Germany during the Cold …

Hispanic Immigration To The United States, Örn B. Bodvarsson, Hendrik F. Van Den Berg

Department of Economics: Faculty Publications

This chapter presents some of the exceptional characteristics of recent Hispanic immigration to the United States. In 2005, there were nearly 40 million Hispanic immigrants and descendants of Hispanic immigrants living in the U.S. The assimilation experience of this large cultural group does not seem to be following the path past immigrants to the U.S. followed. Most third generation Hispanics in the U.S. still find themselves with income and education levels below the U.S. averages. Most forecasts predict that about 60 million Hispanics and Hispanic-Americans will be living in the U.S. by 2030.

The Elasticity Of Taxable Income With Respect To Marginal Tax Rates: A Critical Review, Emmanuel Saez, Joel B. Slemrod, Seth H. Giertz

Department of Economics: Faculty Publications

This paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates (ETI) using tax return data. First, we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient statistic for efficiency and optimal tax analysis. We discuss what other parameters should be estimated when the elasticity is not a sufficient statistic. Second, we discuss conceptually the key issues that arise in the empirical estimation of the elasticity of taxable income using the example of the 1993 top individual income tax rate increase in the …

Prpl: An Open-Source General-Purpose Parallel Raster Processing Programming Library, Qingfeng Guan

Geography Program: Faculty Publications

pRPL is an open-source general-purpose programming library developed by the author to parallelize almost any raster-processing algorithm with any arbitrary neighborhood configuration, and support any data type. This paper introduces the advanced features of pRPL, compares it with other similar programming libraries, and demonstrates the performance of a parallel geographic Cellular Automata (CA) model developed using pRPL with real-world datasets. In conclusion, pRPL effectively reduces the development complexity of parallel programming, and efficiently reduces the computing time.

Tests Of The Dynamic Field Theory And The Spatial Precision Hypothesis: Capturing A Qualitative Developmental Transition In Spatial Working Memory, Anne R. Schutte, John P. Spencer

Department of Psychology: Faculty Publications

This study tested a dynamic field theory (DFT) of spatial working memory and an associated spatial precision hypothesis (SPH). Between three and six years of age there is a qualitative shift in how children use reference axes to remember locations: 3-year-olds’ spatial recall responses are biased toward reference axes after short memory delays, whereas 6-year-olds’ responses are biased away from reference axes. According to the DFT and the SPH, quantitative improvements over development in the precision of excitatory and inhibitory working memory processes lead to this qualitative shift. Simulations of the DFT in Experiment 1 predict that improvements in precision …

Attention Shaping: A Reward-Based Learning Method To Enhance Skills Training Outcomes In Schizophrenia, Steven . M. Silverstein, William D. Spaulding, Anthony A. Menditto, Adam Savitz, Robert P. Liberman, Sarah Berten, Hannah Starobin

Department of Psychology: Faculty Publications

Disturbances in sustained attention commonly interfere with the ability of persons with schizophrenia to benefit from evidence-based psychosocial treatments. Cognitive remediation interventions have thus far demonstrated minimal effects on attention, as have medications. There is thus a gap between the existence of effective psychosocial treatments and patients’ ability to effectively engage in and benefit from them. We report on the results of a multisite study of attention shaping (AS), a behavioral intervention for improving attentiveness and learning of social skills among highly distractible schizophrenia patients. Patients with chronic schizophrenia who were refractory to skills training were assigned to receive either …

The International Law Of Outer Space And Consequences At The National Level For India: Towards An Indian National Space Law?, Frans G. Von Der Dunk

Space, Cyber, and Telecommunications Law Program: Faculty Publications

The discussion on a forum on the famous web-based LinkedIn networking site has already taken off: should India, as party to the four most important international space treaties, also develop a national space law, as other states increasingly are doing? That India is currently one of the leading spacefaring nations in the world is beyond discussion. In itself, however, that does not necessarily necessitate going through the trouble of drafting and implementing a national space law.

This article, however, argues that indeed, following the examples of a growing number of spacefaring states around the world discussed in some detail as …

Studying Oil, Islam, And Women As If Political Institutions Mattered, Alice J. Kang

Department of Political Science: Faculty Publications

By asserting that oil, not Islam, hurts gender equality, Michael Ross (2008) has made an important contribution to the debate on whether Islam bodes ill for women (Fish 2002; Inglehart and Norris 2003; Spierings, Smits, and Verloo 2009). Ross suggests that oil production decreases the number of female workers in countries with occupational segregation. The more women are left out of the formal economy, the fewer opportunities and resources they have for becoming influential political constituencies. According to Ross, "[t]his leaves oil-producing states with atypically strong patriarchal cultures and political institutions" (p. 107). Employing the same set of countries and …

Gestational Risks And Psychiatric Disorders Among Indigenous Adolescents, Les B. Whitbeck, Devan M. Crawford

Department of Sociology: Faculty Publications

This study reports on the effects maternal prenatal binge drinking, cigarette smoking, drug use, and pregnancy and birth complications on meeting criteria for psychiatric disorders at ages 10–12 and 13–15 years among 546 Indigenous adolescents from a single culture in the northern Midwest and Canada. Adolescent DSM-IV psychiatric disorders were assessed with the Diagnostic Interview Schedule for Children-Revised (DISC-R). Results indicate that maternal behaviors when pregnant have significant effects on adolescent psychiatric disorders even when controlling for age and gender of adolescent, family per capita income, living in a single mother household, and adolescent reports of mother’s positive parenting.

Harriet Martineau And Ireland, Brian Conway, Michael R. Hill

Department of Sociology: Faculty Publications

The Victorian sociologist-novelist Harriet Martineau visited Ireland on two different occasions, first in 1832 and again, twenty years later, in 1852, just six years after the Great Famine of 1846, when the country was still very much visibly affected by that event. Her latter journey covered some 1,200 miles and encompassed all four provinces that make up the island of Ireland, north and south. Martineau was not the first foreign visitor to nineteenth century Ireland, of course, but she provided one of the few genuinely sociological interpretations during this time period. This chapter, then, examines Martineau's Irish writings and her …

Managing Performance [In Child Welfare Supervision], Megan E. Paul, Michelle Graef, Erika J. Robinson, Kristin Saathoff

Center on Children, Families, and the Law: Faculty Publications

One of the primary roles of a supervisor is to manage worker performance. Performance management is the "continuous process of identifying, measuring, and developing the performance of individuals and teams and aligning performance with the strategic goals of the organization" (Aguinis, 2007, p. 2). Supervisors must regularly assess current performance levels and take steps to improve performance in a way that is congruent with agency goals. The ultimate goal is to achieve agency objectives through individual and team performance.

To effectively manage performance, supervisors must know what the performance expectations are for workers and clearly communicate these expectations to workers. …

National Student Advertising Competition: Century Council Binge Drinking Campaign, Volation (Team), Ruth Brown, Bettina Burklund, Stacy James, Zach Janky, Phyllis Larsen, Bruce Mitchell, Chuck Piper, Adam Wagler

College of Journalism and Mass Communications: Student Advertising Projects

April 28, 2009 — Advertising students from the University of Nebraska-Lincoln College of Journalism and Mass Communications took home first place in the District 9 American Advertising Federation's National Student Advertising Competition April 24. A first for the program, this win places the team among an elite group of 15 from across the country that will compete for the national title in Washington, D.C., June 4-5. UNL will represent District 9, which includes Nebraska, Iowa, Missouri and Kansas. Judges were unanimous in their decision that the team, Volation, stood far above the other seven teams competing, with a "risky" concept …

Discrepancies In Reporting Of Physical And Sexual Abuse Among Homeless Young Adults, Kimberly A. Tyler, Lisa A. Melander

Department of Sociology: Faculty Publications

This study investigated risk factors for discrepant reporting of physical and sexual abuse among 172 homeless young adults. Discrepant reporting includes situations in which a respondent denies experiencing abuse in general but reports being a victim of specific forms of maltreatment. The results revealed that discrepant reporting rates tended to be highest for minor physical assault and for noncontact sexual abuse. Multivariate results revealed that demographic characteristics were important correlates of both discrepant physical and sexual abuse reporters. Family background characteristics also played a role in discrepant reporting for physical abuse. Overall, some young people with abuse histories are not …

Neighbors In The Pews: Social Status Diversity In Religious Congregations, Philip Schwadel

Department of Sociology: Faculty Publications

For the most part, Americans interact with other people like themselves—those with similar social and economic backgrounds. This homogeneity of social networks contributes in turn to social stratification and to the unequal distribution of social capital and civic integration. Religious congregations offer a rare opportunity for Americans to interact across social status lines. I use data from the 2001 U.S. Congregational Life Survey, which includes survey responses from relatively large samples of attendees nested within a large random sample of congregations, to examine the prevalence of income and education diversity in religious congregations. In contrast to racial diversity, which is …

Taiwan Top Five, Paul Katz

China Beat Blog: Archive 2008-2012

As we prepare to ring out 2008, here are a few thoughts about some of the leading stories that have shaped Taiwan during the past year:

1. Back and Blue: Ma Ying-jeou sweeps into office as Taiwan’s new president, winning a convincing majority of the popular vote based on a platform promising a more stable relationship with China, economic prosperity, and clean government. Cross-Straits tensions have declined markedly, while the opening of direct links should bring great benefits to the citizens of both China and Taiwan. At the same time, however, the economy remains in the doldrums (see #2) …

Zeng Jingyan Accepts Hu Jia’S Sakharov Prize

China Beat Blog: Archive 2008-2012

In late October, the European Parliament announced that it would award this year’s Sakharov Prize for Freedom of Thought to Hu Jia, an activist for HIV/AIDS and the environment currently imprisoned in Beijing. Hu and his wife, Zeng Jingyan, have been adept at using new media to share their message of human rights activism with an international audience, making Hu Jia better known outside China than inside it.

The award ceremony was held December 17. China has continued to protest the award.

Zeng Jingyan, who remains under surveillance at the couple’s apartment, accepted the award via video, subsequently posted on …

Rock Is Not Revolution, Part Ii, Chris Heselton

China Beat Blog: Archive 2008-2012

One of the early rock musicians to make the jump to mainstream and become a household name was Xu Wei. His popularity is probably due to a style that some have called Chinese country or folk rock. This style does not have the explosive rage of heavy metal that many in the popular audience find hard to accept. Instead, he Xu Wei style is a more calm and relaxing melodic rock. One of the distinguishing characteristics of Xu Wei’s music is how similar it is to many of the romantic and nostalgic lyrical themes of pop music. Hometown (故乡, 2000), …

Philosophical Tours Of China, From Dewey To Derrida, Jeff Wasserstrom

China Beat Blog: Archive 2008-2012

Peter Zarrow’s piece last month on Bertrand Russell’s writing on and travels to China may have gotten some of our readers curious about the other two members of the triumverate of famous philosophers mentioned in the introduction to that post: the Indian poet and thinker Rabindranath Tagore and the American pragmatist and educational theorist John Dewey. What each of these two men thought about and did while in China could be well worth a posting. And perhaps in 2009 the blog will run such pieces, as it would be a very appropriate year to do so, at least in Dewey’s …

Rock Is Not Revolution, Chris Heselton

China Beat Blog: Archive 2008-2012

Rock is revolution! Rock is rebellion! Rock is democracy! Well, at least Axl Rose seems to think so with his new album Chinese Democracy. A rock legend singing to democracy in China seems almost poetically fitting. When people tend to think of China and rock music, it almost always comes back to democracy, more specifically, the Tiananmen Square protests of 1989. Rock was the theme genre of the liberal, underground democratic movement. Ever since Cui Jian (崔健) played “I Have Nothing” (一无所有)—sometimes translated as “Nothing to My Name”—at the protest, rock music has been associated with democracy in China, and …

Divine Justice, Paul Katz

China Beat Blog: Archive 2008-2012

As China ascends to its place as a leading nation on the world stage, questions have arisen concerning the role of its legal system. As Joseph Kahn noted in a feature article entitled Deep Flaws, and Little Justice, in China’s Court System, “Justice in China is swift but not sure.” Many protests in China today center on the issue of justice, with one blogger responding to the January 2008 fatal beating by parapolice officials of a man trying to videotape a protest by lamenting “Where is justice? Where is the law? Aren’t there any rules in China?”

My newest book, …

Chinese In Laos, Caroline Finlay

China Beat Blog: Archive 2008-2012

Chimes jingle on gold-painted stupas and teenagers strum guitars to the beat of passing tuk-tuks in Luang Prabang, Laos’ UNESCO World Heritage sight nestled on the Mekong. Sadly, a more obtrusive rhythm has hit the scene: the squawk of walkie-talkie phones. Like a large percentage of Lao’s motorbikes, clothes and electronics, the walkie-talkie phones are a Chinese import, strapped to the belts of the increasingly numerous Chinese tourists visiting Luang Prabang, famous for its now fragile serenity.

China has begun to re-establish ties with sparsely populated Laos, which has historically aligned with Indochina War ally Vietnam. The Chinese have made …
