Communicative Responses To The Painful Self-Disclosures Of Familial And Non-Familial Older Adults, Craig Fowler, Jordan Soliz

Department of Communication Studies: Faculty Publications

Data from 365 college students were used to assess young adults’ communicative responses to older persons’ painful self-disclosures (PSDs). Coupland, Coupland, and Giles (1991) proposed that recipients of PSD may respond to such disclosures via a variety of “next moves.” These responses may broadly be considered to reflect forms of prosocial engagement, passive disengagement, and active disengagement. We investigated whether young adults’ tendency to use certain responses to PSD were influenced by their affective reactions to PSD, their communicative background and characteristics, and the socio-relational context of the encounter in which PSD occurred. Results are discussed with respect to their …

The Lives Of Others: Social Rationality In Animals, Jeffrey R. Stevens, Andrew J. King

Jeffrey Stevens Publications

Darwin (1871) boldly claimed that humans and other animals differ very little in their cognition; a statement that has raised the ire of many scientists (Bolhuis & Wynne, 2009; Penn, Holyoak, & Povinelli, 2008). Rather than stating this continuity as a fact, we will explore the similarities and differences between humans and animals in the social rationality of their decision making. We find this a fruitful exercise because it can profit researchers of both humans and animals. Our purpose here is to provide an evolutionary background of social rationality: Why do animals attend to the lives of others? To this …

Changing Room Cues Reduces The Effects Of Proactive Interference In Clark’S Nutcrackers, Nucifraga Columbiana, Jody L. Lewis, Alan C. Kamil, Kate E. Webbink

Avian Cognition Papers

To determine what factors are important for minimizing interference effects in spatial memory, Clark’s Nutcrackers, Nucifraga columbiana were tested for their spatial memory for two serial lists of locations per day. In this experiment two unique landmark sets were either different between List 1 and List 2 or the same. We found that Nutcrackers were most susceptible to interference when the landmark sets were the same. This study suggests that repeatedly testing animal memory in the same room, with the same cues, can hamper recall due to interference.

Differences In Relative Hippocampus Volume And Number Of Hippocampus Neurons Among Five Corvid Species, Kristy L. Gould, Karl E. Gilbertson, Andrew J. Hrvol, Joseph C. Nelson, Abigail L. Seyfer, Rose M. Brantner, Alan C. Kamil

Avian Cognition Papers

The relative size of the avian hippocampus (Hp) has been shown to be related to spatial memory and food storing in two avian families, the parids and corvids. Basil et al. [Brain Behav Evol 1996;47: 156-164] examined North American food-storing birds in the corvid family and found that Clark’s nutcrackers had a larger relative Hp than pinyon jays and Western scrub jays. These results correlated with the nutcracker’s better performance on most spatial memory tasks and their strong reliance on stored food in the wild. However, Pravosudov and de Kort [Brain Behav Evol 67 (2006), 1-9] raised questions …

Food Webs And Food Sovereignty: Research Agenda For Sustainability, Charles A. Francis, Michelle Miller, Molly Anderson, Nancy Creamer, Michelle Wander, Jacob Park, Thomas Green, Brent Mccown

Department of Agronomy and Horticulture: Faculty Publications

Future food production will be constrained by the scarcity of fossil fuel and fresh water as well as increasing intensity and unpredictability of weather events and climate changes. The assurance of food security and equity for many consumers is complicated by concentration of ownership of land and other production resources, as well as a global corporate food systems model that is driven by profit at the expense of people and the environment. To assess potential alternatives to the contemporary global food chain, well focused research is needed on local food production and food webs where small- and midscale family farms …

Short And Tweet, Sue Burzynski Bullard

College of Journalism and Mass Communications: Faculty Publications

The goal is to help students learn to write clearly and concisely. It reinforces William Zinsser’s advice in “On Writing Well.” He said, “Examine every word you put on paper. You’ll find a surprising number that don’t serve any purpose.” The exercise helps students learn to find the focus of stories. It helps editing students write concise, clear headlines that pull readers into stories. It also helps reporting students learn to summarize stories accurately and briefly — a skill they need as they craft their own ledes.

The Amazing Twitter List Race, Michelle Carr Hassler

College of Journalism and Mass Communications: Faculty Publications

The goal of this assignment is to show students how curating lists on Twitter can help them discover news sources, monitor what is happening in their community and develop story ideas. They complete the assignment as part of a friendly competition in which each student tries to develop a Twitter list with the most news sources. Students often do not follow local news closely and struggle to come up with strong story ideas. This assignment helps them focus by creating one place where they can keep current on events and be inspired.

Prowatch: Critically Thinking About Reporters’ Work, Carla Kimbrough

College of Journalism and Mass Communications: Faculty Publications

ProWatch, an activity in critical thinking, is an assignment that I use in beginning reporting and editing classes, but it can be adapted easily for use in editing and advanced reporting classes. It is designed to make students read the newspaper, identify sources of story ideas, develop interviewing skills, identify Associated Press style, think about presenting stories across platforms and strengthen story organization skills. This assignment is used throughout the semester so that students can gain these skills by critically examining the published work of professional journalists.

Relations Of Parenting Quality, Interparental Conflict, And Overnights With Mental Health Problems Of Children In Divorcing Families With High Legal Conflict, Irwin N. Sandler, Lorey A. Wheeler, Sanford L. Braver

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

The current study examined the associations between child mental health problems and the quality of maternal and paternal parenting, and how these associations were moderated by three contextual factors, quality of parenting by the other parent, interparental conflict, and the number of overnights parents had with the child. Data for the current study come from a sample of divorcing families who are in high legal conflict over developing or maintaining a parenting plan following divorce. Analyses revealed that the associations between child mental health problems and positive maternal and paternal parenting were moderated by the quality of parenting provided by …

Cafio-Prg Develops Novel Approach To Policy Research, Konstantinos Giannakas

CAFIO: Policy Research Group Policy Pagers

The University of Nebraska-Lincoln has received a grant from the United States Department of Agriculture under the Policy Research Centers Program. This grant has supported the establishment of a Policy Research Group (PRG) as part of the Center for Agricultural and Food Industrial Organization (CAFIO) in the Department of Agricultural Economics. CAFIO-PRG is led by the Project Director, Professor Konstantinos Giannakas, and its main focus is on the development of a novel, empirically relevant, integrated, multi-market framework of policy analysis.

Consumer Attitudes And Labeling Regime Key To The Market Potential Of Food Nanotechnology, Miah Tran, Amalia Yiannaka, Konstantinos Giannakas

CAFIO: Policy Research Group Policy Pagers

Research shows that, even though most consumers lack knowledge and understanding of the technology, they nevertheless have strong opinions as to its potential risks and benefits. Advocates are determined to not repeat the mistakes of biotechnology. Understanding the factors determining the market acceptance of food nanotechnology and its potential impact on the different interest groups involved can inform the design of effective policies and strategies governing food nanotechnology innovations.

Country-Of-Origin-Labeling Creates Winners And Losers Among Consumers, Producers, And Retailers, Konstantinos Giannakas, Alejandro Plastina, Daniel Pick

CAFIO: Policy Research Group Policy Pagers

Public Law 107-171, the United States Farm Security and Rural Investment Act of 2002, required country-of-origin labeling (COOL) for beef, lamb, pork, fish, perishable agricultural commodities, and peanuts. While the aim is to benefit domestic consumers by allowing them to make informed decisions, the effects of COOL have been the subject of a heated on-going debate. Advocates of COOL argue the existence of an “overwhelming” consumer support for country of origin information and benefits that substantially outweigh the costs of this labeling regime. Opposing groups have expressed concerns about the potential competitive disadvantage that non-integrated producers might face due to …

Consumer-Oriented Gm Products Can Hurt Producers, Konstantinos Giannakas, Rim Lassoued

CAFIO: Policy Research Group Policy Pagers

Despite their important agronomic benefits to agricultural producers, GM products (GMPs) have been facing a, rather strong, consumer opposition. This opposition varies significantly between countries and so does the countries’ regulatory response to products of biotechnology. While the US treats biotech products as substantially equivalent to their conventional counterparts and does not require their segregation and labeling, the European Union (EU), based on its “precautionary principle” and consumers’ “right to know,” has instituted a mandatory labeling regime that is regarded as the strictest in the world.

Food Labeling Standards Have Significant Welfare And Distributional Impacts, Konstantinos Giannakas, Nicholas Kalaitzandonakes, Alexandre Magnier

CAFIO: Policy Research Group Policy Pagers

Discussions on the appropriate regulatory norms for genetically modified (GM) foods date back to the early 1980s. Thirty years later, a consensus on what such norms should be remains elusive. Some countries, including the United States and Canada, consider GM foods substantially equivalent to their conventional counterparts and do not require segregation and labeling of these products. Others, including the European Union, Japan, South Korea, New Zealand, Australia, and China have introduced mandatory labeling regimes.

Empathy Nudging Increases Conservation Of Farming Land, Natalia V. Czap, Hans J. Czap, Gary D. Lynne, Mark E. Burbach

CAFIO: Policy Research Group Policy Pagers

One of the major challenges of environmental policy with regard to conservation is that it must often rely on voluntary and non-selfish actions of individuals. Traditionally policy makers rely on direct regulation and financial incentives, but both approaches face problems. Regulations may lead to resentment and the costs of perfect enforcement are prohibitively high. Financial incentives can be perverse and may lead to unintended consequences, including crowding out of intrinsic motivation. In addition, behavioral economics and economic psychology studies demonstrate that the assumptions of the neoclassical economic models (such as self-interest only, rationality, and willpower) on which the policy design …

2013 Farm Bill: An Experimental Test Of The Senate And House Proposals, Natalia V. Czap, Hans J. Czap, Gary Lynne, Mark E. Burbach

CAFIO: Policy Research Group Policy Pagers

The 2008 Farm Bill currently guides agricultural and related environmental/conservation policy. Versions proposed by the United States Senate and the House of Representatives, to be implemented in the 2013 Farm Bill after differences are resolved, aim to achieve environmental (and other food related) goals, while also seeking significant spending cuts. While both versions propose to eliminate the Direct Payments program, they differ with respect to how other crop supports should work and whether crop insurance subsidies should be linked to conservation practices. The Senate Bill supports a policy design based on cross‐compliance, that is, crop insurance subsidies are conditional on …

Paleoparasitology: The Origin Of Human Parasites; Paleoparasitologia: A Origem Dos Parasitas Humanos, Adauto Araújo, Karl Reinhard, Luis Fernando Ferreira, Elisa Pucu, Pedro Paulo Chieffi

Karl Reinhard Publications

Parasitism is composed by three subsystems: the parasite, the host, and the environment. There are no organisms that cannot be parasitized. The relationship between a parasite and its host species most of the time do not result in damage or disease to the host. However, in a parasitic disease the presence of a given parasite is always necessary, at least in a given moment of the infection. Some parasite species that infect humans were inherited from pre-hominids, and were shared with other phylogenetically close host species, but other parasite species were acquired from the environment as humans evolved. Human migration …

Ten Misconceptions Concerning Neurobiology And Politics, John R. Hibbing

Department of Political Science: Faculty Publications

Political science is far behind the other social science disciplines in incorporating neurobiological concepts, techniques, and theory. In recent years progress has been made in closing this gap but many in the political science mainstream view the movement with concern or even horror. Though a healthy dose of skepticism is appropriate and beneficial to the scientific endeavor, negative reactions to viewing politics through a neurobiological lens are often based on fundamental misconceptions regarding both neurobiology and politics. In this Reflections essay, I address ten of these misconceptions, including the beliefs that biology is deterministic, reductionist, unnecessary, irrelevant, normatively dangerous, and …

Carbon Storage And Sequestration By Trees In Urban And Community Areas Of The United States, David J. Nowak, Eric J. Greenfield, Robert E. Hoehn, Elizabeth Lapoint

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Carbon storage and sequestration by urban trees in the United States was quantified to assess the magnitude and role of urban forests in relation to climate change. Urban tree field data from 28 cities and 6 states were used to determine the average carbon density per unit of tree cover. These data were applied to statewide urban tree cover measurements to determine total urban forest carbon storage and annual sequestration by state and nationally. Urban whole tree carbon storage densities average 7.69 kg C m^‒2 of tree cover and sequestration densities average 0.28 kg C m^‒2 of tree …

Evaluating Population Connectivity For Species Of Conservation Concern In The American Great Plains, Samuel A. Cushman, Erin L. Landguth, Curtis H. Flather

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing an improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide …

Child Maltreatment Severity And Adult Trauma Symptoms: Does Perceived Social Support Play A Buffering Role?, Sarah E. Evans, Anne L. Steel, David Dilillo

Department of Psychology: Faculty Publications

Objectives: The current study investigates the moderating effect of perceived social support on asso-ciations between child maltreatment severity and adult trauma symptoms. We extend the existing literature by examining the roles of severity of multiple maltreatment types (i.e., sexual, physical, and emotional abuse; physical and emotional neglect) and gender in this process. Methods: The sam-ple included 372 newlywed individuals recruited from marriage license records. Participants com-pleted a number of self-report questionnaires measuring the nature and severity of child maltreat-ment history, perceived social support from friends and family, and trauma-related symptoms. These questionnaires were part of a larger study that investigated …

Medical Adverse Events And Malpractice Litigation In Arizona: By-The-Numbers, Ashley M. Votruba, Michael J. Saks

Department of Psychology: Faculty Publications

A new medical malpractice "crisis" periodically erupts across the United States, invariably producing calls for legislative solutions. Typically, the public is told that rising malpractice insurance premiums are driving doctors out of their practices or out of our state, while increasing the cost of health care, and that those rising insurance rates are the product of too many unwarranted lawsuits resulting in exorbitant damage awards. The legislative fixes typically involve restricting the ability of plaintiffs to bring claims, to prosecute their claims successfully, or to recover full damages if they happen to prevail on their claims. The U.S. Congress sometimes …

Impulsiveness Mediates The Association Between Gabra2 Snps And Lifetime Alcohol Problems, S. Villafuerte, V. Strumba, S. F. Stoltenberg, R. A. Zucker, M. Burmeister

Department of Psychology: Faculty Publications

Genetic variants in GABRA2 have previously been shown to be associated with alcohol measures, electroencephalography (EEG) β waves and impulsiveness-related traits. Impulsiveness is a behavioral risk factor for alcohol and other substance abuse. Here, we tested association between 11 variants in GABRA2 with NEO-impulsiveness and problem drinking. Our sample of 295 unrelated adult subjects was from a community of families with at least one male with DSM-IV alcohol use diagnosis, and from a socioeconomically comparable control group. Ten GABRA2 SNPs (single-nucleotide polymorphisms) were associated with the NEO-impulsiveness (P < 0.03). The alleles associated with higher impulsiveness correspond to the minor alleles identified in previous alcohol dependence studies. All ten SNPs are in linkage disequilibrium (LD) with each other and represent one effect on impulsiveness. Four SNPs and the corresponding haplotype from intron 3 to intron 4 were also associated with Lifetime Alcohol Problems Score (LAPS, P < 0.03) (not corrected for multiple testing). Impulsiveness partially mediates (22.6% average) this relation between GABRA2 and LAPS. Our results suggest that GABRA2 variation in …

Where Are You From? A Validation Of The Foreigner Objectification Scale And The Psychological Correlates Of Foreigner Objectification Among Asian Americans And Latinos, Brian E. Armenta, Richard M. Lee, Stephanie T. Pituc, Kyoung-Rae Jung, Irene J.K. Park, Jose A. Soto, Su Yeong Kim, Seth J. Schwartz

Department of Psychology: Faculty Publications

Many ethnic minorities in the United States consider themselves to be just as American as their European American counterparts. However, there is a persistent cultural stereotype of ethnic minorities as foreigners (i.e., the perpetual foreigner stereotype) that may be expressed during interpersonal interactions (i.e., foreigner objectification). The goal of the present study was to validate the Foreigner Objectification Scale, a brief self-report measure of perceived foreigner objectification, and to examine the psychological correlates of perceived foreigner objectification. Results indicated that the Foreigner Objectification Scale is structurally (i.e., factor structure) and metrically (i.e., factor loadings) invariant across foreign-born and U.S.-born Asian …

As more of us adapt to news and information delivered almost instantly on devices that handily fit into a pocket, we’ve become accustomed to new tools and quick changes. Irving Fang’s second edition of Alphabet to Internet puts it all in perspective, starting with the dawn of writing and including today’s 140-character Tweet. In a word, the impact is mind-boggling.

Integrating Evidence-Based Practices Into Public Relations Education, Karen Freberg, David L. Remund, Kathy Keltner-Previs

College of Journalism and Mass Communications: Faculty Publications

Public relations continue to play an essential and changing role in society, requiring the regular reassessment of the education of future public relations practitioners. Academics and practitioners often differ in how they view the public relations field, how they define the discipline, and how they view the major pedagogical approaches. This paper explores the impact of integrating three different perspectives in public relations education, including practitioner perspective, client perspective, and the evidence-based perspective. Results from students’ reaction papers and an online questionnaire suggest that integrating an evidence-based approach improves the competence and clarity of communications counsel provided by aspiring practitioners.

Is There A Best Cow Size For Beef Cattle Producers?, Matthew Stockton, Sunil P. Dhoubhadel, Leslie Aaron Stalker

Cornhusker Economics

There are individuals in the beef cattle industry who claim there is a need for smaller brood cows, because smaller cows are more efficient and therefore more profitable. On the other hand, there are those who claim the larger the cow the better, and these generally are those who feed calves to slaughter. The proponents of both sides seem to have logical reasons that support their claims. So who is right?
