Ssrn As An Initial Revolution In Academic Knowledge Aggregation And Dissemination, David Bray, Sascha Vitzthum, Benn Konsynski Jan 2010

Ssrn As An Initial Revolution In Academic Knowledge Aggregation And Dissemination, David Bray, Sascha Vitzthum, Benn Konsynski

Sascha Vitzthum

Within this paper we consider our results of using the Social Science Research Network (SSRN) over a period of 18 months to distribute our working papers to the research community. Our experiences have been quite positive, with SSRN serving as a platform both to inform our colleagues about our research as well as inform us about related research (through email and telephoned conversations of colleagues who discovered our paper on SSRN). We then discuss potential future directions for SSRN to consider, and how SSRN might well represent an initial revolution in 21st century academic knowledge aggregation and dissemination. Our paper …


Evaluations Of The Effectiveness Of A Web-Based Graduate Epidemiology Course, Molly A. Rose, Anthony J. Frisby, Michael D. Hamlin, Susan S. Jones Dec 2008

Evaluations Of The Effectiveness Of A Web-Based Graduate Epidemiology Course, Molly A. Rose, Anthony J. Frisby, Michael D. Hamlin, Susan S. Jones

Anthony J Frisby, PhD

An online epidemiology course was developed, implemented, and evaluated for graduate nursing students through the collaborative efforts of nursing faculty and information, education, and instructional design staff of the library at a health sciences university. This epidemiology course is a core curriculum course for graduate nursing students. The course was piloted with 14 students (one student in Romania); the initial online offering ran concurrently with a traditional classroom section. Extensive evaluation data were collected and analyzed to compare the effectiveness of the classroom and distance-learning formats. Areas of evaluation included objective measures, such as midterm and final examination scores and …

Physicians' Experiences With Brca1/2 Testing In Community Settings., Nancy L. Keating, Kathryn A. Stoeckert, Meredith M. Regan, Lisa Digianni, Judy E. Garber

Kathryn Sabella

PURPOSE: We surveyed a national sample of nonacademic physicians who ordered BRCA1/2 testing to understand their implementation of genetic testing and to assess recommendations for surveillance and cancer risk management of women with positive test results.

PATIENTS AND METHODS: We surveyed physicians (N = 611 of 1,050; response rate, 58.2%) practicing in nonacademic settings who ordered BRCA1/2 testing during 2004 to 2005. We described physicians' experiences with testing and used multivariable regression models to identify factors associated with more complete counseling and with recommendations for cancer risk management for a BRCA1 mutation carrier.

RESULTS: Most physicians (68.2%) usually or always …


Gender Specific Differences In The Pros And Cons Of Smoking Among Current Smokers In Eastern Kentucky: Implications For Future Smoking Cessation Interventions, Dana A. Hazen, David M. Mannino, Richard Clayton Dec 2008

Gender Specific Differences In The Pros And Cons Of Smoking Among Current Smokers In Eastern Kentucky: Implications For Future Smoking Cessation Interventions, Dana A. Hazen, David M. Mannino, Richard Clayton

David M. Mannino

This study investigated gender differences in the perceived “pros” and “cons” of smoking using the constructs of decisional balance (DB) and stage of change from the Transtheoretical Model. The population distribution for stage of change among a population-based, cross-sectional survey of 155 current smokers over 40 years was: precontemplation (22.6%), contemplation (41.9%), preparation (35.5%). Results of stepwise regression models indicated significant gender differences in DB were in the preparation stage of change; scores on the DB measure increased 3.94 points (95% CI: 1.94, 5.93) for male smokers. Interventions targeting the “pros” and “cons” of smoking may need to be gender …

Career Development For Transition-Aged Youth With Emotional Disturbances: Exemplary Practices Of Florida Mental Health And Substance Abuse Agencies, Mason G. Haber, Troy Loker, Nicole Deschenes, Hewitt B. Clark

Mason G. Haber

Though an emerging literature on career development practices for transition-age youth with emotional disturbances (TAY w/ED) exists, this literature has not been systematically reviewed. In addition, efforts by publicly-funded sites in Florida to implement such programs have not been comprehensively described. The current project is designed to advance these aims to provide a basis for expanded implementation of career development programs for TAY w/ED in the state.

Improved Feed Protein Fractionation Schemes For Formulating Rations With The Cornell Net Carbohydrate And Protein System, Cristina Lanzas, G A. Broderick, D G. Fox Dec 2008

Improved Feed Protein Fractionation Schemes For Formulating Rations With The Cornell Net Carbohydrate And Protein System, Cristina Lanzas, G A. Broderick, D G. Fox

Cristina Lanzas

Adequate predictions of rumen-degradable protein (RDP) and rumen-undegradable protein (RUP) supplies are necessary to optimize performance while minimizing losses of excess nitrogen (N). The objectives of this study were to evaluate the original Cornell Net Carbohydrate Protein System (CNCPS) protein fractionation scheme and to develop and evaluate alternatives designed to improve its adequacy in predicting RDP and RUP. The CNCPS version 5 fractionates CP into 5 fractions based on solubility in protein precipitant agents, buffers, and detergent solutions: A represents the soluble nonprotein N, B1 is the soluble true protein, B2 represents protein with intermediate rates of degradation, B3 is …


Obstructive Lung Disease Models: What Is Valid, Jill M. Ferdinands, David M. Mannino Dec 2008

Obstructive Lung Disease Models: What Is Valid, Jill M. Ferdinands, David M. Mannino

David M. Mannino

Use of disease simulation models has led to scrutiny of model methods and demand for evidence that models credibly simulate health outcomes. We sought to describe recent obstructive lung disease simulation models and their validation. Medline and EMBASE were used to identify obstructive lung disease simulation models published from January 2000 to June 2006. Publications were reviewed to assess model attributes and four types of validation: first-order (verification/debugging), second-order (comparison with studies used in model development), third-order (comparison with studies not used in model development), and predictive validity. Six asthma and seven chronic obstructive pulmonary disease models were identified. Seven …

The Differentiation Of Hepatocyte-Like Cells From Monkey Embryonic Stem Cells., Xiaocui Ma, Jian Wu, M Zern Nov 2008

The Differentiation Of Hepatocyte-Like Cells From Monkey Embryonic Stem Cells., Xiaocui Ma, Jian Wu, M Zern

jian duan wu

Embryonic stem cells (ESC) hold great potential for the treatment of liver diseases. Here, we report the differentiation of rhesus macaque ESC along a hepatocyte lineage. The undifferentiated monkey ESC line, ORMES-6, was cultured in an optimal culture condition in an effort to differentiate them into hepatocyte-like cells in vitro. The functional efficacy of the differentiated hepatic cells was evaluated using RT-PCR for the expression of hepatocyte specific genes, and Western blot analysis and immunocytochemistry for hepatic proteins such as alpha-fetoprotein (AFP), albumin and alpha1-antitrypsin (alpha1-AT). Functional assays were performed using the periodic acid schiff (PAS) reaction and ELISA. The …


Hoping For A Miracle: Supporting Patients In Transplantation And Cardiac Assist Programs, Katrina Bramstedt Nov 2008

Hoping For A Miracle: Supporting Patients In Transplantation And Cardiac Assist Programs, Katrina Bramstedt

Katrina A. Bramstedt

Purpose of review: Palliative medicine is often viewed as a medical specialty reserved for end of life care. This review focuses on the role that palliative care can play in transplant and cardiac assist device programs, along the continuum of a patient's disease course. Recent findings: In general, transplant and cardiac assist programs do not incorporate palliative medicine during the treatment course, but rather reserve it for when the patient is approaching death and is no longer a candidate for transplant or device therapy. There is a new shift, however, to viewing the practice of aggressive medicine and palliative medicine …


Towards Self-Organizing, Smart Business Networks: Let’S Create ‘Life’ From Inert Information, David Bray, Benn Konsynski Nov 2008

Towards Self-Organizing, Smart Business Networks: Let’S Create ‘Life’ From Inert Information, David Bray, Benn Konsynski

David A. Bray

We review three different theories that can inform how researchers can determine the performance of smart business networks, to include: (1) the Theory of Evolution, (2) the Knowledge-Based Theory of the Firm, and (3) research insights into computers and cognition. We suggest that each of these theories demonstrate that to be generally perceived as smart, an organism needs to be self-organizing, communicative, and tool-making. Consequentially, to determine the performance of a smart business network, we suggest that researchers need to determine the degree to which it is self-organizing, communicative, and tool-making. We then relate these findings to the Internet and …

Fluoranthene, But Not Benzo[A]Pyrene, Interacts With Hypoxia Resulting In Pericardial Effusion And Lordosis In Developing Zebrafish, Cole W. Matson, Alicia R. Timme-Laragy, Richard T. Di Giulio Nov 2008

Fluoranthene, But Not Benzo[A]Pyrene, Interacts With Hypoxia Resulting In Pericardial Effusion And Lordosis In Developing Zebrafish, Cole W. Matson, Alicia R. Timme-Laragy, Richard T. Di Giulio

Alicia R. Timme-Laragy

Previous research has documented several PAHs that interact synergistically, causing severe teratogenicity in developing fish embryos. The coexposure of CYP1A inhibitors (e.g. FL or ANF) with AHR agonists (e.g. BaP or BNF) results in a synergistic increase in toxicity. As with chemical CYP1A inhibitors, it has also been shown that CYP1A morpholinos exacerbate BNF-induced embryotoxicity. We hypothesized that a hypoxia-induced reduction in CYP1A activity in BNF or BaP-exposed zebrafish embryos would similarly enhance pericardial effusion and other developmental abnormalities. BaP, BNF, ANF, and FL exposures, both individually and as BaP+FL or BNF+ANF combinations, were performed under hypoxia and normoxia. CYP1A …


Social Policy, Imperiled Communities, And Hiv/Aids Transmission In Prisons: A Call For Zero Tolerance, Louis F. Graham, Henrie Treadwell, Kisha Braithwaite Nov 2008

Social Policy, Imperiled Communities, And Hiv/Aids Transmission In Prisons: A Call For Zero Tolerance, Louis F. Graham, Henrie Treadwell, Kisha Braithwaite

Louis F Graham

HIV/AIDS and African-American male imprisonment contribute to the destruction of African-American communities. African-American men and HIV/AIDS are disproportionately represented throughout all sectors of the criminal justice industry, including the juvenile justice system. The criminal justice system contributes to unacceptably high African-American male imprisonment rates and HIV prevalence directly via the ‘war on drugs’ and lax enforcement of institutional policy among other things, and indirectly through perpetuation of economic hardship which further exacerbates imprisonment rates, thus closing the loop of a vicious cycle of revolving prison doors and HIV contraction. This article briefly introduces surrounding socio-political issues that contextualizes the ensuing …

A Hybrid Model For Prediction Of Peptide Binding To Mhc Molecules, P. Zhang, V. Brusic, K. Basford Nov 2008

A Hybrid Model For Prediction Of Peptide Binding To Mhc Molecules, P. Zhang, V. Brusic, K. Basford

Ping Zhang

We propose a hybrid classification system for predicting peptide binding to major histocompatibility complex (MHC) molecules. This system combines Support Vector Machine (SVM) and Stabilized Matrix Method (SMM). Its performance was assessed using ROC analysis, and compared with the individual component methods using statistical tests. The preliminary test on four HLA alleles provided encouraging evidence for the hybrid model. The datasets used for the experiments are publicly accessible and have been benchmarked by other researchers.

Fitness And Action Monitoring: Evidence For Improved Cognitive Flexibility In Young Adults, Jason R. Themanson, Matthew B. Pontifex, Charles H. Hillman Nov 2008

Fitness And Action Monitoring: Evidence For Improved Cognitive Flexibility In Young Adults, Jason R. Themanson, Matthew B. Pontifex, Charles H. Hillman

Jason R. Themanson, Ph.D

To improve behavior, one must detect errors and initiate subsequent corrective adaptations. This action monitoring process has been widely studied, but little is known about how one may improve this aspect of cognition. To examine the relationship between cardiorespiratory fitness and action monitoring, we recorded the error-related negativity (ERN), an event-related brain potential believed to index action monitoring, as well as post-error behavioral indices of action monitoring from healthy young adults (18–25 years) who varied in cardiorespiratory fitness. These measures were collected during the execution of flanker tasks emphasizing response accuracy or speed to better assess the specificity of any …


Finding Recurrent Regions Of Copy Number Variation: A Review, Oscar M. Rueda, Ramon Diaz-Uriarte Nov 2008

Finding Recurrent Regions Of Copy Number Variation: A Review, Oscar M. Rueda, Ramon Diaz-Uriarte

Ramon Diaz-Uriarte

Copy number alterations (CNA) in genomic DNA are linked to a variety of human diseases. Although many methods have been developed to analyze data from a single subject, disease-critical genes are more likely to be found in regions that are common or recurrent among diseased subjects. Unfortunately, finding recurrent CNA regions remains a challenge. We review existing methods for the identification of recurrent CNA regions. Methods differ in their working definition of ``recurrent region'', the type of input data, the statistical and computational methods used to identify recurrence, and the biological considerations they incorporate (which play a role in the …


Family Sources Of Educational Gender Inequality In Rural China: A Critical Assessment, Emily C. Hannum, Peggy A. Kong, Yuping Zhang Nov 2008

Family Sources Of Educational Gender Inequality In Rural China: A Critical Assessment, Emily C. Hannum, Peggy A. Kong, Yuping Zhang

Emily C. Hannum

In this paper, we investigate the gender gap in education in rural northwest China. We first discuss parental perceptions of abilities and appropriate roles for girls and boys; parental concerns about old-age support; and parental perceptions of different labor market outcomes for girls’ and boys’ education. We then investigate gender disparities in investments in children, children’s performance at school, and children’s subsequent attainment. We analyze a survey of nine to twelve year-old children and their families conducted in rural Gansu Province in the year 2000, along with follow-up information about subsequent educational attainment collected seven years later. We complement our …

Application Of Two Machine Learning Algorithms To Genetic Association Studies In The Presence Of Covariates, Bareng As Nonyane, Andrea S. Foulkes Nov 2008

Application Of Two Machine Learning Algorithms To Genetic Association Studies In The Presence Of Covariates, Bareng As Nonyane, Andrea S. Foulkes

Andrea S Foulkes

Background - Population-based investigations aimed at uncovering genotype-trait associations often involve high-dimensional genetic polymorphism data as well as information on multiple environmental and clinical parameters. Machine learning (ML) algorithms offer a straightforward analytic approach for selecting subsets of these inputs that are most predictive of a pre-defined trait. The performance of these algorithms, however, in the presence of covariates is not well characterized. Methods and Results - In this manuscript, we investigate two approaches: Random Forests (RFs) and Multivariate Adaptive Regression Splines (MARS). Through multiple simulation studies, the performance under several underlying models is evaluated. An application to a cohort …


Gene Set Enrichment Analysis For Non-Monotone Association And Multiple Experimental Categories, Rongheng Lin, Shuangshuang Dai, Richard D. Irwin, Alexandra N. Heinloth, Gary A. Boorman, Leping Li Nov 2008

Gene Set Enrichment Analysis For Non-Monotone Association And Multiple Experimental Categories, Rongheng Lin, Shuangshuang Dai, Richard D. Irwin, Alexandra N. Heinloth, Gary A. Boorman, Leping Li

Rongheng Lin

Background Recently, microarray data analyses using functional pathway information, e.g., gene set enrichment analysis (GSEA) and significance analysis of function and expression (SAFE), have gained recognition as a way to identify biological pathways/processes associated with a phenotypic endpoint. In these analyses, a local statistic is used to assess the association between the expression level of a gene and the value of a phenotypic endpoint. Then these gene-specific local statistics are combined to evaluate association for pre-selected sets of genes. Commonly used local statistics include t-statistics for binary phenotypes and correlation coefficients that assume a linear or monotone relationship between a …
