Homestead National Monument, Vegetation Mapping Project [Poster], Kelly Kindscher, Hayley Kilroy, Jennifer Delisle, Quinn Long, Hillary Loring, Kevin Dobbs, Jim Drake

United States National Park Service: Publications

Homestead National Monument was created in 1936 to celebrate the significance of the Homestead Act of 1862, which granted 160 acres of free land to claimants. This was one of the most significant and enduring events in the westward expansion of the United States. The site is the first tract homesteaded under the act by Daniel Freemen, and encompasses 184 acres in Gage County, west of Beatrice, Nebraska.

This unique site also hosts the oldest prairie restoration in the National Park system and the second-oldest tallgrass prairie restoration known. This park unit also has a small remnant of native tallgrass …

Effective Selectors? Interlibrary Loan Patrons As Monograph Purchasers: A Comparative Examination Of Price And Circulation-Related Performance, David C. Tyler, Joyce C. Melvin, Yang Xu, Marylou Epp, Anita M. Kreps

University of Nebraska-Lincoln Libraries: Faculty Publications

In the library literature, a great deal of interest in patron-driven collection development has recently been expressed, especially in those programs that link acquisitions with interlibrary loan. However, the implementation of such programs has been limited, at least in part because of concerns over the potential for wasteful spending. The authors will attempt to address this common concern by assessing whether monies spent via a patron-driven acquisitions program were more or less effective than monies spent via traditional modes of acquisition.

Social Networking Sites: What They Are And How To Navigate Them (Participant Manual), Maria Deguzman, Deborah J. Weitzenkamp Dr., Anita Hall, Deanna Vansickel-Staudt, Car Mun Kok, Jessica Lake

Kimmel Education and Research Center: Faculty and Staff Publications

The use of social networking sites such as Facebook and LinkedIn has dramatically increased in recent years. Today, over 50 percent of teens and 35 percent of adults in the U.S. are using at least one type of social networking site. If used well, these sites can have many personal and professional benefits. Social networking can be a fun way to communicate with others, and an effective way to expand your social and professional connections. Nonetheless, it is important to practice good judgment and proper “netiquette” when developing personal profiles and interacting with others through such sites. This community program …

EXECUTIVE SUMMARY

For more than a century jcpenney has been a dependable retailer and a regular shopping destination for the American family. Founded in 1902 by James Cash Penney, the department store was established on the principle of the golden rule. Throughout the years they have developed a reputation for putting their customers first and providing them with their everyday needs.

However, in the minds of women between the ages of 25-34, the image of jcpenney has not been consistent. For a demographic so interested in fashion, these women prefer to do most of their shopping in specialty clothing stores …

A Synergetic Use Of Satellite Imagery From Sar And Optical Sensors To Improve Coastal Flood Mapping In The Gulf Of Mexico, Naira Chaouch, Marouane Temimi, Scott Hagen, John Weishampel, Stephen Medeiros, Reza Khanbilvardi

United States Department of Commerce: Staff Publications

This work proposes a method for detecting inundation between semi-diurnal low and high water conditions in the northern Gulf of Mexico using high-resolution satellite imagery. Radarsat 1, Landsat imagery and aerial photography from the Apalachicola region in Florida were used to demonstrate and validate the algorithm. A change detection approach was implemented through the analysis of red, green and blue (RGB) false colour composites image to emphasise differences in high and low tide inundation patterns. To alleviate the effect of inherent speckle in the SAR images, we also applied ancillary optical data. The flood-prone area for the site was delineated …

Wolves, Canis Lupus, Carry And Cache The Collars Of Radio-Collared White-Tailed Deer, Odocoileus Virginianus, They Killed, Michael E. Nelson, L. David Mech

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

Wolves (Canis lupus) in northeastern Minnesota cached six radio-collars (four in winter, two in spring-summer) of 202 radio-collared White-tailed Deer (Odocoileus virginianus) they killed or consumed from 1975 to 2010. A Wolf bedded on top of one collar cached in snow. We found one collar each at a Wolf den and Wolf rendezvous site, 2.5 km and 0.5 km respectively, from each deer’s previous locations.

The Logos Of The Blogosphere: Flooding The Zone, Invention, And Attention In The Lott Imbroglio, Damien S. Pfister

Department of Communication Studies: Faculty Publications

This essay examines the significance of a particular metaphor, flooding the zone, which gained prominence as an account of bloggers' argumentative prowess in the wake of Senator Trent Lott's toast at Strom Thurmond's centennial birthday party. I situate the growth of the blogosphere in the context of the political economy of the institutional mass media at the time and argue that the blogosphere is an alternative site for the invention of public argument. By providing an account of how the blogosphere serves as a site of invention by flooding the zone with densely interlinked coverage of a controversy, this essay …

Technological Change And Productivity Analysis In Nebraska, Dereje B. Megeressa

Department of Agricultural Economics: Faculty Publications

Productivity growth has been an important source of US economic growth throughout the century

The years since 1940 have been an even faster growth in agricultural productivity (Ball, et.al. 1998; Tokgöz, 2002).

Several factors have been identified as the most important sources of productivity change in US agriculture.

Chandler (1962) attributes over 75 percent of the growth in productivity to technological factors in the post war years.

In Nebraska, several productivity studies conducted that include (Perrin et al, 2001; ball et al, 2001; and Palestina et al(2009).

None of the studies disaggregate land into poor and good …

Feminism, Neoliberalism, And Social Studies, Mardi Schmeichel

Department of Teaching, Learning, and Teacher Education: Faculty Publications

The purpose of this article is to analyze the sparse presence of women in social studies education and to consider the possibility of a confluence of feminism and neoliberalism within the most widely distributed National Council for the Social Studies (NCSS) publication, Social Education. Using poststructural conceptions of discourse, the author applies second-wave feminist theory and Fraser’s (2009) work on neoliberalism as lenses to illuminate the limited attention to women and feminism in this text during the 1980s in order to better understand how women have been marginalized in social studies education and to consider the possibility that the …

Schooling And The Everyday Ruptures Transnational Children Encounter In The United States And Mexico, Edmund T. Hamann, Víctor Zúñiga

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Using examples of students in Mexico who used to attend US schools and examples from Georgia of students who used to and might again attend Mexican schools, this chapter considers how an unremarkable, quotidian activity—the act of attending school—can become means for transnationally mobile children to experience shock, disconnection, and a reiterated sense of dislocation if schools are incompletely responsive to learners' biographies.

The Anglo Politics Of Latino Education: The Role Of Immigration Scripts, Edmund T. Hamann

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In the 41 states without a substantial historic Latino population, large-scale schooling of Latinos is a comparatively new issue and the nature of that schooling is fundamentally shaped by how the more established (usually Anglo) populations understand this task. This chapter describes the understandings that led to, but also limited, one particularly comprehensive attempt in Georgia to respond to Latino newcomers. In that sense, this is a study of the cosmologies that can undergird the politics of schooling of Latinos. This chapter utilizes the concept of the script, or broadly shared storylines about how things are or should be, to …

Holding Parents Responsible: Is Vicarious Responsibility The Public’S Answer To Juvenile Crime?, Eve M. Brank, Edie Greene, Katherine Hochevar

Department of Psychology: Faculty Publications

Parental responsibility laws hold parents accountable for the delinquent behaviors of their children even when parents’ actions are not the direct cause of an offense. Despite the prevalence of these laws, we know little about their perceived fairness. Is it reasonable to make parents vicariously responsible for outcomes they could not have foreseen and, if so, under what circumstances? Our series of three studies addressed those questions by systematically examining the impact of various situational and dispositional factors on public opinions regarding parental responsibility. Respondents attributed most of the responsibility for a crime to the child, and attributions of responsibility …

Head Impact Exposure In Collegiate Football Players, Joseph J. Crisco, Bethany J. Wilcox, Jonathan G. Beckwith M.S., Jeffrey J. Chu M.S., Ann-Christine Duhaime M.D., Steve Rowson, Stefan M. Duma Ph.D., Arthur C. Maerlender, Thomas W. Mcallister M.D., Richard M. Greenwald Ph.D.

Department of Psychology: Faculty Publications

In American football, impacts to the helmet and the resulting head accelerations are the primary cause of concussion injury and potentially chronic brain injury. The purpose of this study was to quantify exposures to impacts to the head (frequency, location and magnitude) for individual collegiate football players and to investigate differences in head impact exposure by player position. A total of 314 players were enrolled at three institutions and 286,636 head impacts were recorded over three seasons. The 95th percentile peak linear and rotational acceleration and HITsp (a composite severity measure) were 62.7g, 4378 rad/s², and 32.6, respectively. …

Sign- Vs. Goal-Tracking In A Feature Positive Discrimination Task With Nicotine: Importance Of Spatial Location Of The Conditional Stimulus, Amanda M. Dion, Carmela M. Reichel, Rick A. Bevins

Department of Psychology: Faculty Publications

We assessed whether sign-tracking developed along with goal-tracking in a Pavlovian drug discrimination task. Rats had nicotine sessions intermixed with saline sessions. For nicotine sessions, 15-sec illumination of a light near (Experiment 1) or far (Experiment 2) from the dipper receptacle was followed by sucrose. Saline sessions were similar except sucrose was withheld. Regardless of location, the light evoked goal-tracking only on nicotine sessions. Only rats with the light near the dipper developed sign-tracking.

Nicotine Trained As A Negative Feature Passes The Retardation-Of-Acquisition And Summation Tests Of A Conditioned Inhibitor, Jennifer E. Murray, Andrew W. Walker, Chia Li, Nicole R. Wells, Rachel D. Penrod, Rick A. Bevins

Department of Psychology: Faculty Publications

Nicotine functions as a negative feature in a Pavlovian discriminated goal-tracking task. Whether withholding of responding to the conditional stimulus (CS) reflects nicotine functioning as a conditioned inhibitor is unknown. Accordingly, the present research sought to determine whether nicotine trained as a negative feature passed the retardation-of-acquisition and summation tests, thus characterizing it as a pharmacological (interoceptive) conditioned inhibitor. In the retardation test, rats received either nicotine (0.4 mg/kg) or chlordiazepoxide (5 mg/kg) negative feature training in which the drug state signaled when a 15-sec light CS would not be paired with sucrose; light was paired with sucrose on intermixed …

An Examination Of Nmda Receptor Contribution To Conditioned Responding Evoked By The Conditional Stimulus Effects Of Nicotine, Jennifer E. Murray, Andrew W. Walker, Robert J. Polewan, Rick A. Bevins

Department of Psychology: Faculty Publications

Rationale—Research using a drug discriminated goal-tracking (DGT) task showed that the Nmethyl- D-aspartate (NMDA) channel blocker MK-801 (dizocilpine) reduced the nicotine-evoked conditioned response (CR).

Objectives—Given the unknown mechanism of the effect, Experiment 1 replicated the MK-801 results and included tests with NMDA receptor ligands. Experiments 2a and 2b tested whether MK-801 pretreatment blocked DGT via a state-dependency effect.

Methods—In Experiment 1, adult male Sprague–Dawley rats received intermittent access to liquid sucrose following nicotine (0.4 mg base/kg); no sucrose was delivered on intermixed saline sessions. Conditioning was indicated by increased anticipatory dipper entries (goal-tracking) on nicotine compared to saline sessions. Antagonism …

Thinking About The Future Cognitive Remediation Therapy—What Works And Could We Do Better?, Til Wykes, William D. Spaulding

Department of Psychology: Faculty Publications

This article reviews progress in the development of effective cognitive remediation therapy (CRT) and its translational process. There is now enough evidence that cognitive difficulties experienced by people with schizophrenia can change and that the agenda for the next generation of studies is to increase these effects systematically through cognitive remediation. We examine the necessary steps and challenges of moving CRT to treatment dissemination. Theories which have been designed to explain the effects of cognitive remediation, are important but we conclude that they are not essential for dissemination which could progress in an empirical fashion. One apparent barrier is that …

Serotonin Transporter (5-Httlpr) Genotype And Childhood Trauma Are Associated With Individual Differences In Decision Making, Scott F. Stoltenberg, Melissa K. Lehmann, Cynthia Anderson, Parthasarathi Nag, Cheryl Anagnopoulos

Department of Psychology: Faculty Publications

The factors that influence individual differences in decision making are not yet fully characterized, but convergent evidence is accumulating that implicates serotonin (5-HT) system function. Therefore, both genes and environments that influence serotonin function are good candidates for association with risky decision making. In the present study we examined associations between common polymorph isms in the serotonin transporter gene (SLC6A4; 5-HTTLPR and rs25531)' the experience of childhood trauma and decision making on the Iowa gambling task (IGT) in 391 (64.5% female) healthy Caucasian adults. Homozygosity for the 5-HTTLPR L allele was associated with riskier decision making in the first block …

Nicotine Competes With A Visual Stimulus For Control Of Conditioned Responding, Jennifer E. Murray, Nicole R. Wells, Rick A. Bevins

Department of Psychology: Faculty Publications

Environmental stimuli that co-occur with tobacco use come to evoke drug-related conditioned responses (CRs) that appear involved in continued use of nicotine-containing products. In rats, nicotine can serve as a conditional stimulus (CS) for non-drug unconditioned stimuli (USs), prompting the question of whether the nicotine CS can compete with, or overshadow, a non-drug environmental stimulus for control of a CR. In Experiment 1, male Sprague-Dawley rats were assigned to a group [0, 0.01, 0.03, 0.045, or 0.06 mg nicotine (base)/kg/infusion]. During each session, there were 10 intravenous infusions followed by a 30-second houselight to form a compound CS. At light …

Preface To “When Does Sample Matter In Juror Decision‐Making Research? Differences Between College Student And Representative Samples Of Jurors”, Joel D. Lieberman, Daniel A. Krauss, Richard L. Weiner

Department of Psychology: Faculty Publications

It has been 45 years since Kalven and Zeisel (1966) published their groundbreaking book The American Jury. Since that time, the field of jury decision‐making has grown dramatically. A multitude of social and cognitive influences on juror behavior have been identified, as has the influence of many procedural factors such as jury size, jury decision rule, and jury instructions. Several broad theories have been developed that integrate findings, such as commonsense justice (Finkel, 1995, 2001) and the story model (Pennington & Hastie, 1992). Interestingly, although The American Jury may have marked the beginning of the era of jury decision‐making …

What Are We Studying? Student Jurors, Community Jurors, And Construct Validity, Stacie R. Keller, Richard L. Weiner

Department of Psychology: Faculty Publications

Jury researchers have long been concerned about the generalizability of results from experiments that utilize undergraduate students as mock jurors. The current experiment examined the differences between 120 students (55 males and 65 females, mean age = 20 years) and 99 community members (49 males and 50 females, mean age = 42 years) in culpability evaluations for homicide and sexual assault cases. Explicit attitude measures served as indicators of bias for sexual assault, defendant, and homicide adjudication. Results revealed that student and community participants showed different biases on these general explicit attitude measures and these differences manifested in judgments of …

Greenleaf's 'Best Test' Of Servant Leadership: A Multilevel Analysis, Robert W. Hayden

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

This study empirically tests Robert Greenleaf’s (1970) seminal articulation of servant leadership. The four personal outcomes he theorized (health, wisdom, freedom-autonomy, and service orientation) were tested against established dimensions of servant leadership. All correlations were significant and positive. Using multilevel analysis, the predictive strength of these servant leadership dimensions were assessed at two levels within an organization, and explained. Implications and future direction of research were discussed.

Populism And Human Rights In Theory And Practice: Chavez's Venezuela And Fujimori's Peru, Joseph P. Braun

Department of Political Science: Dissertations, Theses, and Student Research

Despite ample literature on the topic of populism itself, much less has been written on the specific relationship between populism and human rights. First, I discuss the relationship between populist ideology and human rights in theory. I argue that populism is inconsistent with human rights accounts because of its rejection of pluralism and vilification of the ‘other.’ Second, I explore the relationship between populism as a political strategy and its impact on human rights under two Latin American regimes. I argue that despite its tendency to produce short-term gains in economic and social development, a review of the two cases …

Returning Attention To Policy Content In Diffusion Study, John M. Fulwider

Department of Political Science: Dissertations, Theses, and Student Research

Policy diffusion research pays virtually no attention to policy content. Yet we should expect content to shape the adoption of any policy--this is what legislators and policy makers, after all, fight about. Thus the extent and speed of diffusion likely critically depend on policy content, which the current literature virtually ignores. This dissertation shows how we can better understand policy diffusion by taking policy content seriously. Paying attention to policy content, including how it is debated and understood by legislators, has immediate payoffs in the sense that two literatures largely ignored until now by diffusion researchers-- policy typologies and policy …

Adapting An Evidence-Based Intervention To Improve Social And Behavioral Competence In Head Start Children: Evaluating The Effectiveness Of Teacher–Child Interaction Training, Christopher Campbell

Department of Psychology: Dissertations, Theses, and Student Research

Empirical studies indicate that as many as 35% of Head Start children meet the diagnostic criteria for oppositional defiant disorder or conduct disorder (Webster-Stratton & Hammond, 1998). Without early intervention, these problematic behaviors may become stable across childhood and adolescence (Campbell, 1995), increasing the likelihood of academic problems, school drop-out, substance abuse, delinquency, and violence (Snyder, 2001). Head Start children are also more likely to enter school with significant deficits in social-emotional readiness, with a many as 40% demonstrating delays in social competencies and communication abilities (Kaiser et al., 2000). Longitudinal research indicates that early gaps in social competence for …

The Recovery Of Cognitive And Social Cognitive Functioning In Response To Social Cognition Interaction Training Administered In Community Settings: A Longitudinal Study, Lena Reddy

Department of Psychology: Dissertations, Theses, and Student Research

Psychosocial rehabilitation for persons with Serious Mental Illness (SMI) encompasses recovery of functioning in a broad array of domains, including neurocognitive, social cognitive, interpersonal, occupational, and self-care abilities. There is extensive evidence that improvements in these domains are possible as a result of targeted interventions, and that these improvements may generalize to other areas of daily functioning. The current study explored rehabilitative change over time among adults with SMI that were attending outpatient day centers. Social Cognition and Interaction Training (SCIT), a cognitive-behavioral skills-training modality, was implemented during the time period in which the data was collected. Forty adults participated …

Journal Impact Factor, Scott H. Church

Department of Communication Studies: Dissertations, Theses, and Student Research

In a recent issue of Human Communication Research, Thomas Hugh Feeley notes, “journal impact rankings provide objective data for tenure, promotion, and, possibly, grant review committees on the quality of scholars’ work.” Though the metric is widely regarded as the conventional measure to assess the influence of a journal in both the social and physical sciences, many doubts regarding its effectiveness have been raised. This essay assesses the effectiveness of the Journal Impact Factor (JIF) as a scholarly metric. After first considering the metric's history and developing a working definition of JIF (part one), next I delineate its strengths and …

Scimago, Getachew Dinku Godana

Department of Communication Studies: Dissertations, Theses, and Student Research

The degree to which a scholar’s work is cited by others has been regarded as an indicator of its scientific impact relative to other researchers in the web of scholarly communications. Likewise, various metrics based on citation counts have been developed to evaluate the impact of scholarly journals. Recently there has emerged a new research trend aimed at developing impact metrics that consider not only “the raw number of citations received by a scientific agent, but also the importance or influence of the actors who issue those citations.” These new metrics represent scientific impact as a function not of just …

Attitudes, William A. Cunningham, Ingrid J. Haas, Andrew Jahn

Department of Political Science: Faculty Publications

This chapter reviews social neuroscience research that links social psychological attitudes and evaluative processes to their presumed neural bases. The chapter is organized into four parts. The first section discusses how attitude representations are transformed into evaluative states that can be used to guide thought and action. The next two sections address the related processes of attitude learning and change. The final section discusses applications of these concepts for the study of prejudice and political behavior.

Assumed Transmission In Political Science: A Call For Bringing Description Back In, Scott L. Althaus, Nathaniel Swigger, Svitlana Chernykh, David J. Hendry, Sergio C. Wals, Christopher Tiwald

Department of Political Science: Faculty Publications

News outlets cannot serve as reliable conveyors of social facts, nor do their audiences crave such content. Nonetheless, much political science scholarship assumes that objective information about social, political, and economic topics is routinely transmitted to the mass public through the news. This article addresses the problem of selection bias in news content and illustrates the problem with a content analytic study of New York Times coverage given to American war deaths in five major conflicts that occurred over the past century. We find that news coverage of war deaths is unrelated to how many American combatants have recently died. …
