The Importance Of Interagency Collaboration For Crossover Youth, Emily M. Wright, Ryan E. Spohn, Joselyne Chenane, Nicholas Juliano

Criminology and Criminal Justice Faculty Publications

Crossover or dually-involved youth are youth enmeshed in the child welfare (CWS) and juvenile justice systems (JJS). Given their dual status and high needs, attention has recently focused on how to best respond to them in an integrated, interagency fashion. The Crossover Youth Practice Model (CYPM) is designed to facilitate interagency collaboration between the CWS and JJS in order to enhance services and diversion to these youth. This study reports on the benefits and challenges that the JJS and CWS, as well as the personnel working within them, experience by participating in a CYPM effort in a Midwestern county, and …

Archived Publications

The Census Bureau estimates the July 1, 2016 population of Nebraska to be 1,907,116. The state hit a new population milestone, exceeding the 1.9 million mark for the first time. Seven years passed between exceeding 1.8 million for the first time in 2009 and this new milestone in 2016. This 7-year timespan ties for the shortest such duration to gain 100,000 persons with the 7-year period from 1992 to 1999, when the state rose from 1.6 million to 1.7 million residents. See table below. Projections by our office in 2013 suggest it will take 9 years to move from 1.9 …

What Is Answer Set Programming To Propositional Satisfiability, Yuliya Lierler

Computer Science Faculty Publications

Propositional satisfiability (or satisfiability) and answer set programming are two closely related subareas of Artificial Intelligence that are used to model and solve difficult combinatorial search problems. Satisfiability solvers and answer set solvers are the software systems that find satisfying interpretations and answer sets for given propositional formulas and logic programs, respectively. These systems are closely related in their common design patterns. In satisfiability, a propositional formula is used to encode problem specifications in a way that its satisfying interpretations correspond to the solutions of the problem. To find solutions to a problem it is then sufficient to use a …

Chapter 9: Biomechanics, Nicholas Stergiou, Daniel Blanke, Sara A. Myers, Ka-Chun Siu

Journal Articles

Biomechanics is a discipline. A discipline deals with understanding, predicting, and explaining phenomena within a content domain, and biomechanics is the study of the human body in motion. By applying

principles from mechanics and engineering, biomechanists are able to study the forces that act on the body and the effects they produce (Bates, 1991). Hay (1973) describes biomechanics as the science that examines forces acting on and within a biological structure and the effects produced by such forces, whereas Alt (1967) describes biomechanics as the science that investigates the effect of internal and external forces on human and animal bodies …

The Rim And The Ancient Mariner: The Nautical Horizon Affects Postural Sway In Older Adults, Justin Munafo, Michael G. Wade, Nick Stergiou, Thomas A. Stoffregen

Journal Articles

On land, the spatial magnitude of postural sway (i.e., the amount of sway) tends to be greater when participants look at the horizon than when they look at nearby targets. By contrast, on ships at sea, the spatial magnitude of postural sway in young adults has been greater when looking at nearby targets and less when looking at the horizon. Healthy aging is associated with changes in the movement patterns of the standing body sway, and these changes typically are interpreted in terms of age-related declines in the ability to control posture. To further elucidate the mechanisms associated with these …

Contextual Influences On The Relations Between Physical And Relational Aggression And Peer Victimization, Jonathan Santo, Ellyn Bass, Luz Stella-Lopez, William M. Bukowski

Psychology Faculty Publications

Previous studies have demonstrated that several contextual factors influence the relationship between aggression and peer victimization in early adolescence, including gender of the same-sex peer group and gender composition of the school. The current study replicated and expanded on this research by examining the moderating influences of gender of the same-sex peer group, same-sex peer group norms, and classroom gender composition in a sample of early adolescents from Barranquilla, Colombia. Multilevel modeling analyses indicated that both relational and physical aggression were positive predictors of peer victimization. Relationally aggressive girls were at a lower risk for victimization while physically aggressive girls …

Expectation-Centered Analytics For Instructors And Students, Suzanne L. Dazo

Student Work

Learning analytics is the measurement, collection, analysis, and reporting of data about learners and their contexts. An outcome and primary goal of learning analytics should be to inform instructors, who are primary stakeholders, so that they can make effective decisions in their courses. To support instructor inquiry, I apply theory on reflective practice to learning analytic development. Articulating an instructor's pedagogical expectations is one way to begin facilitating a reflective practice. Expectations based on instructor goals serve as a natural next step and the springboard from which data can be collected. I hypothesize that a learning analytic that encodes and …

Myth Or Reality? Crowdsourcing As A Complex Problemsolving Model: Evidence From Software Developed By The Crowd And Professionals, Abhishek Tripathi

Student Work

Crowdsourcing is a problem-solving model. Conventional theory suggests that solving complex problems is a province of professionals, people with sufficient knowledge about the domain. Prior literature indicated that the crowd is also a great source for solving complex problems. However, there is a lack of experimental research to support that crowdsourcing is a useful model for complex problem-solving (CPS), especially in the software development context. The broad goal of this dissertation is to address this research gap and improve understanding of crowdsourcing as a viable and effective CPS model. This research proposed and tested a research model of perceived quality …

Sensitivity To The Ferguson Effect: The Role Of Managerial Organizational Justice, Justin Nix, Scott E. Wolfe

Criminology and Criminal Justice Faculty Publications

Purpose

We argue that the police have been adversely impacted by Ferguson-related negative publicity in ways beyond the supposed increase in crime (e.g., reduced motivation and increased perception of danger). Further, we suggest that organizational justice is a key factor that influences officers' sensitivity to such Ferguson Effects.

Methods

We used a sample of 510 sheriff's deputies surveyed 6 months after the incident in Ferguson. We explored whether organizational justice is associated with deputies' sensitivity to several manifestations of the Ferguson Effect using OLS and ordered logistic regression models.

Results

The results demonstrated that deputies who believed their supervisors were …

Indifference To Chaotic Motion May Be Related To Social Disinterest In Children With Autism, Joshua L. Haworth, Anastasia Kyvelidou, Wayne Fisher, Nicholas Stergiou

Journal Articles

Children with autism spectrum disorder tend to have little interest in the presence, actions, and motives of other persons. In addition, these children tend to present with a limited and overly redundant movement repertoire, often expressing hyperfixation and aversion to novelty. We explore whether this is related to a more fundamental lack of appreciation for various temporal dynamics, including periodic, chaotic, and aperiodic motion structures. Seven children with ASD (age, gender, and height matched with children without ASD) were asked to stand and watch the motion of a visual stimulus displayed on a large (55") video monitor. Gaze and posture …

Assessing Data Quality In Citizen Science, Margaret Kosmala, Andrea Wiggins, Alexandra Swanson, Brooke Simmons

Information Systems and Quantitative Analysis Faculty Publications

Ecological and environmental citizen‐science projects have enormous potential to advance scientific knowledge, influence policy, and guide resource management by producing datasets that would otherwise be infeasible to generate. However, this potential can only be realized if the datasets are of high quality. While scientists are often skeptical of the ability of unpaid volunteers to produce accurate datasets, a growing body of publications clearly shows that diverse types of citizen‐science projects can produce data with accuracy equal to or surpassing that of professionals. Successful projects rely on a suite of methods to boost data accuracy and account for bias, including iterative …

Murine Models Of Splenic Marginal Zone Lymphoma: A Role For Cav1?, Chelsey L. Patten, Christine E. Cutucache

Biology Faculty Publications

Dozens of murine models of indolent and aggressive B-cell lymphomas have been generated to-date. These include those manifesting chronic lymphocytic leukemia (CLL), diffuse large B-cell lymphoma (DLBCL) as well as xenografts of mantle cell lymphoma (MCL). These models have led to an improved understanding of disease etiology, B-cell biology, immunomodulation, and the importance of the tumor microenvironment. Despite these efforts in CLL, DLBCL, and MCL, considerably little progress toward a model of splenic marginal zone lymphoma (SMZL) has been accomplished. Herein, we describe the similarities and differences between CLL, MCL, and SMZL, and highlight effective murine models that mimic disease …

Autism Spectrum Disorder Prevalence Rates In The United States: Methodologies, Challenges, And Implications For Individual States, Emily Ramsey, Lisa Kelly-Vance, Joseph A. Allen, Olivia Rosol, Michael Yoerger

Psychology Faculty Publications

Many different studies have been conducted to determine the prevalence rates of Autism Spectrum Disorder (ASD) in the United States. The methodologies of these studies have varied, resulting in a multitude of publications with differing prevalence rates. Because there is such a wide range in the results of prevalence studies, it may be difficult for individual states to determine their rates. Accurate prevalence rates are important to obtain for many different reasons including increasing advocacy and awareness, increasing funding, and proper allocation of services for individuals with ASD and their families. Additionally, prevalence studies can be used to assess which …

Ethics At The End Of Life: A Teaching Tool, Cara L. Wallace, Kara J. Thielman, Andrea N. Cimino, Heidi Adams Rueda

Social Work Faculty Publications

Social workers rarely receive education and training in the areas of grief, bereavement, and death and dying, which may lead to difficulties in compassionately and ethically addressing concerns in end-of-life or grief-related contexts. This article presents actual and potential outcomes from three challenging end-of-life case studies using Mattison’s ethical decision-making model as a framework. The case studies were drawn from student interviews with experienced master’s-level social workers. This pedagogical article helps to promote self-reflection and consideration of ethical issues in grief and death-related situations as well as supplement death education and ethics curricula to include end-of-life content.

Baker, Jarosøaw Søawek, Christine Klein, Katja Hückelheim, Meike Kasten, Zbigniew K. Wszolek

Biology Faculty Publications

Olfactory dysfunction is associated with normal aging, multiple neurodegenerative disorders, including Parkinson’s disease, Lewy body disease and Alzheimer’s disease, and other diseases such as diabetes, sleep apnea and the autoimmune disease myasthenia gravis. The wide spectrum of neurodegenerative disorders associated with olfactory dysfunction suggests different, potentially overlapping, underlying pathophysiologies. Studying olfactory dysfunction in presymptomatic carriers of mutations known to cause familial parkinsonism provides unique opportunities to understand the role of genetic factors, delineate the salient characteristics of the onset of olfactory dysfunction, and understand when it starts relative to motor and cognitive symptoms. We evaluated olfactory dysfunction in 28 carriers …

Social Workers’ Roles In Supporting The Sexual And Relational Health Of Children With Disabilities, Heidi Adams Rueda, Sharon J. Bolin, Kristen Faye Linton, Lela Rankin Williams, Eva Pesta

Social Work Faculty Publications

The purpose of this study was to understand social workers’ roles in meeting the sexual and relational health needs of children (aged 3–11) with disabilities. We conducted semi-structured interviews with 12 social workers from a range of practice settings. A phenomenological lens privileged the perspectives of social workers in their definitions of disability and sought to convey the meaning they assigned to their experiences of working with children in practice concerning matters related to sexual and relational health. Social workers enacted a broad definition of disability and often came to work with youth in contexts labeled as sexually problematic. In …

Failure Of Multiculturalism? Immigration, Radical Islamism, And Identity Politics In Europe, Fatos Tarifa, Monica Di Monte

International Dialogue

This paper addresses the issue of how Europe’s ethnic and cultural mix is changing drastically by the large numbers of culturally diverse, especially Muslim immigrants, as well as problems that Western European governments face today as they try to deal with unintended consequences of their liberal policies of multiculturalism. In light of this discussion, radical Islamism and identity politics are seen as long-term challenges for all liberal democracies. We argue that extremist voices among the right-wing populist parties in many Western European countries opposed to immigration and increasingly mobilized around the issue of Muslim minorities, may spur resentment and political …
