Differential Expressions Of The Alternatively Spliced Variant Mrnas Of The Μ Opioid Receptor Gene, Oprm1, In Brain Regions Of Four Inbred Mouse Strains, Jin Xu, Zhigang Lu, Mingming Xu, Grace C. Rossi, Benjamin Kest, Amanda R. Waxman, Gavril W. Pasternak, Ying-Xian Pan
Differential Expressions Of The Alternatively Spliced Variant Mrnas Of The Μ Opioid Receptor Gene, Oprm1, In Brain Regions Of Four Inbred Mouse Strains, Jin Xu, Zhigang Lu, Mingming Xu, Grace C. Rossi, Benjamin Kest, Amanda R. Waxman, Gavril W. Pasternak, Ying-Xian Pan
Publications and Research
The µ opioid receptor gene, OPRM1, undergoes extensive alternative pre-mRNA splicing in rodents and humans, with dozens of alternatively spliced variants of the OPRM1 gene. The present studies establish a SYBR green quantitative PCR (qPCR) assay to more accurately quantify mouse OPRM1 splice variant mRNAs. Using these qPCR assays, we examined the expression of OPRM1 splice variant mRNAs in selected brain regions of four inbred mouse strains displaying differences in µ opioid-induced tolerance and physical dependence: C56BL/6J, 129P3/J, SJL/J and SWR/J. The complete mRNA expression profiles of the OPRM1 splice variants reveal marked differences of the variant mRNA expression among …
Between-Domain Relations Of Students' Academic Emotions And Their Judgments Of School Domain Similarity, Thomas Goetz, Ludwig Haag, Anastasiya A. Lipnevich, Melanie M. Keller, Anne C. Frenzel, Antonie P. M. Collier
Between-Domain Relations Of Students' Academic Emotions And Their Judgments Of School Domain Similarity, Thomas Goetz, Ludwig Haag, Anastasiya A. Lipnevich, Melanie M. Keller, Anne C. Frenzel, Antonie P. M. Collier
Publications and Research
With the aim to deepen our understanding of the between-domain relations of academic emotions, a series of three studies was conducted. We theorized that between-domain relations of trait (i.e., habitual) emotions reflected students' judgments of domain similarities, whereas between-domain relations of state (i.e., momentary) emotions did not. This supposition was based on the accessibility model of emotional self-report, according to which individuals' beliefs tend to strongly impact trait, but not state emotions. The aim of Study 1 (interviews; N = 40; 8th and 11th graders) was to gather salient characteristics of academic domains from students' perspective. In Study 2 ( …
Focal Cortical Thickness Correlates Of Exceptional Memory Training In Vedic Priests, Giridhar P. Kalamangalam, Timothy M. Ellmore
Focal Cortical Thickness Correlates Of Exceptional Memory Training In Vedic Priests, Giridhar P. Kalamangalam, Timothy M. Ellmore
Publications and Research
The capacity for semantic memory—the ability to acquire and store knowledge of the world—is highly developed in the human brain. In particular, semantic memory assimilated through an auditory route may be a uniquely human capacity. One method of obtaining neurobiological insight into memory mechanisms is through the study of experts. In this work, we study a group of Hindu Vedic priests, whose religious training requires the memorization of vast tracts of scriptural texts through an oral tradition, recalled spontaneously during a lifetime of subsequent spiritual practice. We demonstrate focal increases of cortical thickness in regions of the left prefrontal lobe …
Explaining Racial/Ethnic Disparities In Use Of High-Volume Hospitals: Decision-Making Complexity And Local Hospital Environments, Karl Kronebusch, Bradford H. Gray, Mark Schlesinger
Explaining Racial/Ethnic Disparities In Use Of High-Volume Hospitals: Decision-Making Complexity And Local Hospital Environments, Karl Kronebusch, Bradford H. Gray, Mark Schlesinger
Publications and Research
Racial/ethnic minorities are less likely to use higher-quality hospitals than whites. We propose that a higher level of informationrelated complexity in their local hospital environments compounds the effects of discrimination and more limited access to services, contributing to racial/ethnic disparities in hospital use. While minorities live closer than whites to high-volume hospitals, minorities also face greater choice complexity and live in neighborhoods with lower levels of medical experience. Our empirical results reveal that it is generally the overall context associated with proximity, choice complexity, and local experience, rather than differential sensitivity to these factors, that provides a partial explanation of …

Joint Influence Of Individual Choices, Parenting Practices, And Physician Advice On Adolescent Obesity, Nebraska, 2008, Hongmei Wang, Jungyoon Kim, Dejun Su, Liyan Xu, Li-Wu Chen, Terry T-K. Huang
Publications and Research
Introduction Reducing childhood obesity remains a public health priority given its high prevalence and its association with increased risk of adult obesity and chronic diseases. The objective of this study was to examine the joint influence of multiple risk factors on adolescent overweight status. Methods We conducted a random-digit-dialed telephone survey of adolescents aged 12 to 19 years in fall 2008 in a Midwestern city in Nebraska. On the basis of survey data for 791 youths aged 12 to 18 years, we conducted latent class analysis to group youths by the joint occurrence of dietary behavior, physical activity, parenting practices, …
Human Sexuality As A Critical Subfield In Social Work, Emily Mccave, Benjamin C. Shepard, Virginia Ramseyer Winter
Human Sexuality As A Critical Subfield In Social Work, Emily Mccave, Benjamin C. Shepard, Virginia Ramseyer Winter
Publications and Research
Human sexuality is of vital importance to social work practitioners, educators, and scholars. Yet historically, the profession’s leadership around it has waxed and waned, impacting practice. This article discusses the importance of human sexuality as a critical subfield within social work. It suggests that the mechanisms, namely textbooks, journals, and national conferences, for stimulating human sexuality social work scholarship are limited. The authors assert that the taboo of human sexuality limits the advancement of a cohesive professional discourse and contributes to the continued oppression of marginalized populations. Recommendations for providing better support for those who study, teach, and practice in …
Dynamics Of Alpha Control: Preparatory Suppression Of Posterior Alpha Oscillations By Frontal Modulators Revealed With Combined Eeg And Event-Related Optical Signal, Kyle E. Mathewson, Diane M. Beck, Tony Ro, Edward L. Maclin, Kathy A. Low, Monica Fabiani, Gabriele Gratton
Dynamics Of Alpha Control: Preparatory Suppression Of Posterior Alpha Oscillations By Frontal Modulators Revealed With Combined Eeg And Event-Related Optical Signal, Kyle E. Mathewson, Diane M. Beck, Tony Ro, Edward L. Maclin, Kathy A. Low, Monica Fabiani, Gabriele Gratton
Publications and Research
We investigated the dynamics of brain processes facilitating conscious experience of external stimuli. Previously, we proposed that alpha (8–12 Hz) oscillations, which fluctuate with both sustained and directed attention, represent a pulsed inhibition of ongoing sensory brain activity. Here we tested the prediction that inhibitory alpha oscillations in visual cortex are modulated by top–down signals from frontoparietal attention networks. We measured modulations in phase-coherent alpha oscillations from superficial frontal, parietal, and occipital cortices using the event-related optical signal (EROS), a measure of neuronal activity affording high spatiotemporal resolution, along with concurrently recorded EEG, while participants performed a visual target detection …

The talk also discusses the James Bond film Die Another Day.
In What Senses Are Free Spirits Free?, Christa Davis Acampora
In What Senses Are Free Spirits Free?, Christa Davis Acampora
Publications and Research
My broadest claim in this article is, unsurprisingly, that there are multiple senses of freedom associated with the freedom of the free spirit. These include both positive and negative senses – that is, when describing how free spirits are free, Nietzsche sometimes characterizes this as freedom to do something, and sometimes as freedom from certain kinds of constraints. In this article, I do not aim to provide an exhaustive catalogue of the different senses invoked in Nietzsche’s ‘free spirit’ texts. Instead, I wish to highlight some particular senses, including some that are less frequently discussed in the scholarly literature and …
The Ideological And Organizational Origins Of The United Federation Of Teachers' Opposition To The Community Control Movement In The New York City Public Schools, 1960-1968, Stephen Brier
Publications and Research
This article explores the origins and ideological practice of public school teacher unionism as it was articulated and revealed in New York City before and during the epochal strike against an experiment in community control of neighborhood schools undertaken by the United Federation of Teachers in the fall of 1968 that closed down the city’s massive public school system for weeks and put almost 1 million school children in the street. How and why did unionized New York City public school teachers support the particular kind of trade unionism that the UFT and its president, Albert Shanker, embodied and practiced …

The Effect Of Menu Labeling With Calories And Exercise Equivalents On Food Selection And Consumption, Charles Platkin, Ming-Chin Yeh, Kimberly Hirsch, Ellen Weiss Wiewel, Chang-Yun Lin, Ho-Jui Tung, Victoria H. Castellanos
Publications and Research
Background Better techniques are needed to help consumers make lower calorie food choices. This pilot study examined the effect of menu labeling with caloric information and exercise equivalents (EE) on food selection. Participants, 62 females, ages 18-34, recruited for this study, ordered a fast food meal with menus that contained the names of the food (Lunch 1 (L1), control meal). One week later (Lunch 2 (L2), experiment meal), participants ordered a meal from one of three menus with the same items as the previous week: no calorie information, calorie information only, or calorie information and EE. Results There were no …
Sticking Your Neck Out And Burying The Hatchet: What Idioms Reveal About Embodied Simulation, Natalie A. Kacinik
Sticking Your Neck Out And Burying The Hatchet: What Idioms Reveal About Embodied Simulation, Natalie A. Kacinik
Publications and Research
Idioms are used in conventional language twice as frequently as metaphors, but most research, particularly recent work on embodiment has focused on the latter. However, idioms have the potential to significantly deepen our understanding of embodiment because their meanings cannot be derived from their component words. To determine whether sensorimotor states could activate idiomatic meaning, participants were instructed to engage in postures/actions reflecting various idioms (e.g.,sticking your neck out) relative to non-idiomatic control postures/actions while reading and responding to statements designed to assess idiomatic meaning. The results showed that statements were generally more strongly endorsed after idiom embodiment than control …

Publications and Research
Many brain regions exhibit lateral differences in structure and function, and also incorporate new neurons in adulthood, thought to function in learning and in the formation of new memories. However, the contribution of new neurons to hemispheric differences in processing is unknown. The present study combines cellular, behavioral, and physiological methods to address whether 1) new neuron incorporation differs between the brain hemispheres, and 2) the degree to which hemispheric lateralization of new neurons correlates with behavioral and physiological measures of learning and memory. The songbird provides a model system for assessing the contribution of new neurons to hemispheric specialization …
Atypical Multisensory Integration In Niemann-Pick Type C Disease – Towards Potential Biomarkers, Gizely N. Andrade, Sophie Molholm, John S. Butler, Alice Brown Brandwein, Steven U. Walkley, John J. Foxe
Atypical Multisensory Integration In Niemann-Pick Type C Disease – Towards Potential Biomarkers, Gizely N. Andrade, Sophie Molholm, John S. Butler, Alice Brown Brandwein, Steven U. Walkley, John J. Foxe
Publications and Research
Background: Niemann-Pick type C (NPC) is an autosomal recessive disease in which cholesterol and glycosphingolipids accumulate in lysosomes due to aberrant cell-transport mechanisms. It is characterized by progressive and ultimately terminal neurological disease, but both pre-clinical studies and direct human trials are underway to test the safety and efficacy of cholesterol clearing compounds, with good success already observed in animal models. Key to assessing the effectiveness of interventions in patients, however, is the development of objective neurobiological outcome measures. Multisensory integration mechanisms present as an excellent candidate since they necessarily rely on the fidelity of long-range neural connections between the …
Nesting Behaviour Influences Species-Specific Gas Exchange Across Avian Eggshells, Steven J. Portugal, Golo Maurer, Gavin H. Thomas, Mark E. Hauber, Tomáš Grim, Phillip Cassey
Nesting Behaviour Influences Species-Specific Gas Exchange Across Avian Eggshells, Steven J. Portugal, Golo Maurer, Gavin H. Thomas, Mark E. Hauber, Tomáš Grim, Phillip Cassey
Publications and Research
Carefully controlled gas exchange across the eggshell is essential for the development of the avian embryo. Water vapour conductance (GH2O) across the shell, typically measured as mass loss during incubation, has been demonstrated to optimally ensure the healthy development of the embryo while avoiding desiccation. Accordingly, eggs exposed to sub-optimal gas exchange have reduced hatching success. We tested the association between eggshell GH2O and putative life-history correlates of adult birds, ecological nest parameters and physical characteristics of the egg itself to investigate how variation in GH2O has evolved to maintain optimal water loss across a diverse set of nest environments. …
Dog Movie Stars And Dog Breed Popularity: A Case Study In Media Influence On Choice, Stefano Ghirlanda, Alberto Acerbi, Harold Herzog
Dog Movie Stars And Dog Breed Popularity: A Case Study In Media Influence On Choice, Stefano Ghirlanda, Alberto Acerbi, Harold Herzog
Publications and Research
Fashions and fads are important phenomena that influence many individual choices. They are ubiquitous in human societies, and have recently been used as a source of data to test models of cultural dynamics. Although a few statistical regularities have been observed in fashion cycles, their empirical characterization is still incomplete. Here we consider the impact of mass media on popular culture, showing that the release of movies featuring dogs is often associated with an increase in the popularity of featured breeds, for up to 10 years after movie release. We also find that a movie's impact on breed popularity correlates …
Transcranial Direct Current Stimulation Facilitates Cognitive Multi-Task Performance Differentially Depending On Anode Location And Subtask, Melissa Scheldrup, Pamela M. Greenwood, Ryan Mckendrick, Jon Strohl, Marom Bikson, Mahtab Alam, R. Andy Mckinley, Raja Parasuraman
Transcranial Direct Current Stimulation Facilitates Cognitive Multi-Task Performance Differentially Depending On Anode Location And Subtask, Melissa Scheldrup, Pamela M. Greenwood, Ryan Mckendrick, Jon Strohl, Marom Bikson, Mahtab Alam, R. Andy Mckinley, Raja Parasuraman
Publications and Research
There is a need to facilitate acquisition of real world cognitive multi-tasks that require long periods of training (e.g., air traffic control, intelligence analysis, medicine). Non-invasive brain stimulation—specifically transcranial Direct Current Stimulation (tDCS)—has promise as a method to speed multi-task training. We hypothesized that during acquisition of the complex multi-task Space Fortress, subtasks that require focused attention on ship control would benefit from tDCS aimed at the dorsal attention network while subtasks that require redirection of attention would benefit from tDCS aimed at the right hemisphere ventral attention network. We compared effects of 30 min prefrontal and parietal stimulation to …
Perceived Health Status Of Women With Knee Osteoarthritis: A Cross-Sectional Study Of The Relationships Of Age, Body Mass, Pain And Walking Limitations, Ray Marks
Publications and Research
Persons with knee osteoarthritis (OA) often experience considerable physical disability. Although some studies suggest women with this condition suffer more than men, few have attempted to characterize the magnitude and that impact of this condition specifically among women with moderate knee osteoarthritis as well as the relationships that exist between their perceived health status and well established physical, emotional and perceptual factors found in this disease. This exploratory study strove to better understand factors that underpin the perceived impact of the condition, and to describe the extent of pain and function among women with mild to moderate knee osteoarthritis, and …
An Information Theory Account Of Cognitive Control, Jin Fan
An Information Theory Account Of Cognitive Control, Jin Fan
Publications and Research
Our ability to efficiently process information and generate appropriate responses depends on the processes collectively called cognitive control. Despite a considerable focus in the literature on the cognitive control of information processing, neural mechanisms underlying control are still unclear, and have not been characterized by considering the quantity of information to be processed. A novel and comprehensive account of cognitive control is proposed using concepts from information theory, which is concerned with communication system analysis and the quantification of information. This account treats the brain as an information-processing entity where cognitive control and its underlying brain networks play a pivotal …

Statistical Signs Of Social Influence On Suicides, Hygor Piaget M. Melo, André A. Moreira, Élcio Batista, Hernán A. Makse, José S. Andrade
Publications and Research
By treating the suicide as a social fact, Durkheim envisaged that suicide rates should be determined by the connections between people and society. Under the same framework, he considered that crime is bound up with the fundamental conditions of all social life. The social effect on the occurrence of homicides has been previously substantiated, and confirmed here, in terms of a superlinear scaling relation: by doubling the population of a Brazilian city results in an average increment of 135% in the number of homicides, rather than the expected isometric increase of 100%, as found, for example, for the mortality due …
Student Reading Practices In Print And Electronic Media, Nancy M. Foasberg
Student Reading Practices In Print And Electronic Media, Nancy M. Foasberg
Publications and Research
This paper reports a diary-based qualitative study on college students’ reading habits with regard to print and electronic media. Students used a form to record information about their reading practices for twelve days, including length of reading event, location, format used, and the purpose of reading. Students tended to use print for academic and long-form reading and to engage with it more deeply. Although electronic resources were sometimes used for academic purposes, students often used them for shorter and nonacademic reading. Students found electronic media convenient, but most of them did not wish to switch to electronic media for their …
The Longitudinal Effect Of Drug Use On Productivity Status Of Nonmetropolitan African American Young Adults, María Isabel Roldós
The Longitudinal Effect Of Drug Use On Productivity Status Of Nonmetropolitan African American Young Adults, María Isabel Roldós
Publications and Research
The purpose of this study was to investigate the longitudinal effect of marijuana and heavy alcohol use on the productivity status of nonmetropolitan African American young adults. This analysis was based on secondary data from the Family and Community Health Study. For alcohol, the study evaluated the effects on productivity status for individuals with heavy alcohol use trajectories from adolescence into young adulthood while marijuana effects were evaluated during the period when adolescents are more likely to have initiated usage (14-16 years of age). Productivity status was measured when study participants were between 18 and 21 years, for both alcohol …
The Debt Penalty: Exposing The Financial Barriers To Offender Reintegration, Douglas N. Evans
The Debt Penalty: Exposing The Financial Barriers To Offender Reintegration, Douglas N. Evans
Publications and Research
Financial debt associated with legal system involvement is a pressing issue that affects the criminal justice system, offenders, and taxpayers. Mere contact with the criminal justice system often results in fees and fines that increase with progression through the system. Criminal justice fines and fees punish offenders and are designed to generate revenue for legal systems operating on limited budgets. However, fines and fees often fail to accomplish this second goal because many offenders are too poor to pay them. If they do not pay their financial obligations, they may be subject to late fees and interest requirements, all of …
Facile Synthesis Of 1-Alkoxy-1h-Benzo- And 7-Azabenzotriazoles From Peptide Coupling Agents, Mechanistic Studies, And Synthetic Applications, Mahesh K. Lakshman, Manish K. Singh, Mukesh Kumar, Raghu Ram Chamala, Vijayender R. Yedulla, Domenick Wagner, Evan Leung, Lijia Yang, Asha Matin, Sadia Ahmad

(1H-Benzo[d][1,2,3]triazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP), 1H-benzo[d][1,2,3]triazol-1-yl 4-methylbenzenesulfonate (Bt-OTs), and 3H-[1,2,3]triazolo[4,5-b]pyridine-3-yl 4-methylbenzenesulfonate (At-OTs) are classically utilized in peptide synthesis for amide-bond formation. However, a previously undescribed reaction of these compounds with alcohols in the presence of a base, leads to 1-alkoxy-1H-benzo- (Bt-OR) and 7-azabenzotriazoles (At-OR). Although BOP undergoes reactions with alcohols to furnish 1-alkoxy-1H-benzotriazoles, Bt-OTs proved to be superior. Both, primary and secondary alcohols undergo reaction under generally mild reaction conditions. Correspondingly, 1-alkoxy-1H-7-azabenzotriazoles were synthesized from At-OTs. Mechanistically, there are three pathways by which these peptide-coupling agents can react with alcohols. From 31P{1H}, [18O]-labeling, and other chemical experiments, phosphonium and tosylate derivatives of …

Rejection Positivity Predicts Trial-To-Trial Reaction Times In An Auditory Selective Attention Task: A Computational Analysis Of Inhibitory Control, Sufen Chen, Robert D. Melara
Publications and Research
A series of computer simulations using variants of a formal model of attention (Melara and Algom, 2003) probed the role of rejection positivity (RP), a slow-wave electroencephalographic (EEG) component, in the inhibitory control of distraction. Behavioral and EEG data were recorded as participants performed auditory selective attention tasks. Simulations that modulated processes of distractor inhibition accounted well for reaction-time (RT) performance, whereas those that modulated target excitation did not. A model that incorporated RP from actual EEG recordings in estimating distractor inhibition was superior in predicting changes in RT as a function of distractor salience across conditions. A …

The Neotropical butterfly Dryas iulia has been collected from several locations in Thailand and Malaysia since 2007, and has been observed breeding in the wild, using introduced Passiflora foetida as a larval host plant. The butterfly is bred by a butterfly house in Phuket, Thailand, for release at weddings and Buddhist ceremonies, and we hypothesized that this butterfly house was the source of wild, Thai individuals. We compared wing patterns and COI barcodes from two, wild Thai populations with individuals obtained from this butterfly house. All Thai individuals resemble the subspecies D. iulia modesta, and barcodes from wild and captive …
