Evaluation Of Animal Model Research, Kenneth J. Shapiro Dec 2015

Evaluation Of Animal Model Research, Kenneth J. Shapiro

Kenneth J. Shapiro, PhD

It is argued that a concept of evaluation of animal models that is broader and more useful than validation is available. Productive generativity refers to the degree to which a model furthers understanding and leads to more-effective treatment interventions. Results of the application of this novel evaluative frame to several animal models of eating disorders show that this animal-based research has not been productive. The question of the relation between clinic and animal laboratory is discussed.


The Ingrown World Of Animal Model Research In Psychology, Kenneth J. Shapiro Dec 2015

The Ingrown World Of Animal Model Research In Psychology, Kenneth J. Shapiro

Kenneth J. Shapiro, PhD

In the previous essay, I described the proper function of models in science as heuristic, as a way of generating hypotheses about the actual object of study. Turning to animal models in psychology, I offered a general characterization of that enterprise using sham feeding, an animal model of the eating disorder called bulimia, as an example. In this final of three essays, I offer an evaluation of this animal model strategy that largely employs the tools of social science. I close with a recommendation and a prediction.


Understanding Dogs Through Kinesthetic Empathy, Social Construction, And History, Kenneth J. Shapiro Dec 2015

Understanding Dogs Through Kinesthetic Empathy, Social Construction, And History, Kenneth J. Shapiro

Kenneth J. Shapiro, PhD

The term, "come into animal presence," she takes from the title of a Denise Levertov poem. The poem, which reads, in part, "What joy when the insouciant armadillo glances at us and doesn't quicken his trotting across the track into the palm bush. What is this joy?" This joy is the possibility of our being in the presence of animals for "(t)he armadillo has some intention to pursue in the palm forest." This joy, to which I invite you here, consists in dwelling in that presence, in inhabiting that intention, that armored but guileless world of the armadillo. I will …

Load Carriage Distance Run And Pushups Tests: No Body Mass Bias And Occupationally Relevant, Paul M. Vanderburgh, Nicholas S. Mickley, Philip A. Anloague, Kimber Lucius Dec 2015

Load Carriage Distance Run And Pushups Tests: No Body Mass Bias And Occupationally Relevant, Paul M. Vanderburgh, Nicholas S. Mickley, Philip A. Anloague, Kimber Lucius

Philip A. Anloague

Recent research has demonstrated body mass (M) bias in military physical fi tness tests favoring lighter, not just leaner, service members. Mathematical modeling predicts that a distance run carrying a backpack of 30 lbs would eliminate M-bias. The purpose of this study was to empirically test this prediction for the U.S. Army push-ups and 2-mile run tests. Two tests were performed for both events for each of 56 university Reserve Offi cer Training Corps male cadets: with (loaded) and without backpack (unloaded). Results indicated signifi cant M-bias in the unloaded and no M-bias in the loaded condition for both events. …


Social Motivation Is Associated With Elevated Salivary Cortisol In Boys With An Asd, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos Nov 2015

Social Motivation Is Associated With Elevated Salivary Cortisol In Boys With An Asd, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

Because social communication difficulties and stress are common in children with an ASD, and because it has been hypothesised that the two are related, the association between these two variables was investigated in a sample of 90 boys with an ASD and who were aged between 6 years and 12 years of age. The Social Responsiveness Scale (SRS) was completed by the parents of these boys about their sons, plus salivary cortisol samples were collected from the boys. Results indicated that only one aspect of the boys' SRS was significantly correlated with cortisol—Social Motivation (SM). Factor analyses revealed two discrete …


Age-Related Differences In The Association Between Stereotypic Behaviour And Salivary Cortisol In Young Males With An Autism Spectrum Disorder, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos Nov 2015

Age-Related Differences In The Association Between Stereotypic Behaviour And Salivary Cortisol In Young Males With An Autism Spectrum Disorder, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

To identify if age influenced the relationship between one of the central symptoms of Autism Spectrum Disorder (ASD) and physiological stress, the association between stereotypic behaviour (SB) and stress-related cortisol concentrations was examined in a sample of 150 young males with an ASD. Parent-rated SB was significantly correlated with cortisol concentrations for boys aged 6 years to 12 years but not for adolescents aged 13 years to 18 years. This age-related difference in this association was not a function of cortisol concentrations but was related to differences in SB across these two age groups. IQ did not have a significant …

Wildlife In U.S. Cities: Managing Unwanted Animals, John Hadidian Nov 2015

Wildlife In U.S. Cities: Managing Unwanted Animals, John Hadidian

John Hadidian, PhD

Conflicts between people and wild animals in cities are undoubtedly as old as urban living itself. In the United States it is only of late, however, that many of the species now found in cities have come to live there. The increasing kind and number of human-wildlife conflicts in urbanizing environments makes it a priority that effective and humane means of conflict resolution be found. The urban public wants conflicts with wildlife resolved humanely, but needs to know what the alternative management approaches are, and what ethical standards should guide their use. This paper examines contemporary urban wildlife control in …


Influential Factors In Undergraduate Nursing Research Analysis, Anunay Bhattacharya, Marian Tabi Nov 2015

Influential Factors In Undergraduate Nursing Research Analysis, Anunay Bhattacharya, Marian Tabi

Anunay Bhattacharya

Undergraduate college students often tend to view research courses with negative attitudes. These negative attitudes have well documented in numerous studies. Prior research studies have documented that negative attitudes toward a course have been found to serve as barriers to learning.  In addition, these negative attitudes influence the amount of effort one is willing to invest in learning a subject.  Studies have shown that research experience in undergraduate education is associated with graduate education and future career in research. Nursing students in many undergraduate baccalaureate degree programs are often required to take a course in research to understand and utilize evidence-based …

Increases In Peptide Y-Y Levels Following Oat Β-Glucan Ingestion Are Dose-Dependent In Overweight Adults, Eleanor J. Beck, Linda C. Tapsell, Marijka J. Batterham, Susan M. Tosh, Xu-Feng Huang

Dr Marijka Batterham

Peptide Y-Y (PYY) is an anorexigenic hormone implicated in appetite control, and β-glucan is a fiber known to affect appetite. We hypothesized that plasma PYY levels would increase in overweight human adults consuming increasing doses of β-glucan. The objective was to test whether the effect could be seen with β-glucan delivered through extruded cereals containing a high β-glucan oat bran with demonstrated high molecular weight and solubility. Fourteen subjects consumed a control meal and 3 cereals of varying β-glucan concentration (between 2.2 and 5.5 g), and blood samples were collected over 4 hours. Analysis of raw PYY data showed a …

Adult Attention Deficit Disorder And Aggressive Behaviour: An Exploration Of Relationships Between Brown Attention-Deficit Disorder Scales And The Aggression Questionnaire, Mitchell K. Byrne, Natalie Parletta, David G. Webster, Marijka Batterham, Barbara J. Meyer

Dr Marijka Batterham

Aggressive and violent behaviour is often associated with a diagnosis of attention-deficit hyperactivity disorder (ADHD). This article investigates the relationship between adult attention deficit disorder (ADD) and aggressive cognitions. The Aggression Questionnaire and the Brown Attention-Deficit Disorder Scales were administered to two samples: a "low-risk sample" comprising university students (n = 60), and a "high-risk sample" of prison inmates (n = 117). The prevalence of "probable ADD" was found to be higher in the prison sample (33%), compared with the university sample (20%). There were moderate correlations >r = .5 (p < .01) between total ADHD and Aggression Questionnaire scores in …

Energy Expenditure Does Not Differ, But Protein Oxidation Rates Appear Lower In Meals Containing Predominantly Meat Versus Soy Sources Of Protein, Sze Yen Tan, Marijka Batterham, Linda C. Tapsell Nov 2015

Energy Expenditure Does Not Differ, But Protein Oxidation Rates Appear Lower In Meals Containing Predominantly Meat Versus Soy Sources Of Protein, Sze Yen Tan, Marijka Batterham, Linda C. Tapsell

Dr Marijka Batterham

Background: High protein meals produce 3 relevant effects in weight management: i) higher thermogenic cost, ii) enhanced fat oxidation, and iii) greater satiation. Pork has been reported to be more thermogenic than soy, suggesting meat protein may be superior to plant protein in a high-protein weight loss diet context. In this study, we aimed to compare the effects of high-protein meals using meat, dairy, and soy sources respectively. Methods: This crossover feeding trial measured energy expenditure, substrate oxidation, and satiety levels of 12 adults during 8-hour stays in a whole-room calorimeter. The 3 isoenergetic high-protein test meals (30% protein, 40% …

Oat Β-Glucan Supplementation Does Not Enhance The Effectiveness Of An Energy-Restricted Diet In Overweight Women, Eleanor J. Beck, Linda C. Tapsell, Marijka J. Batterham, Susan M. Tosh, Xu-Feng Huang

Dr Marijka Batterham

Epidemiological evidence shows an inverse relationship between dietary fibre intake and body weight gain. Oat β-glucan, a soluble fibre alters appetite hormones and subjective satiety in acute meal test studies, but its effects have not been demonstrated with chronic consumption. The present study aimed to test the effects in women of two different doses of oat β-glucan on weight loss and hormones associated with appetite regulation. In a 3-month parallel trial, sixty-six overweight females were randomised into one of three 2 MJ energy-deficit diets: a control and two interventions including 5–6 g or 8–9 g β-glucan. Anthropometric and metabolic variables …

Conversion Of Australian Food Composition Data From Ausnut1999 To 2007 In The Clinical Trial Context, Elizabeth P. Neale, Yasmine C. Probst, Rebecca Thorne, Qingsheng Zhang, Jane E. O'Shea, Marijka J. Batterham, Linda C. Tapsell

Dr Marijka Batterham

An Australian food composition database, AUSNUT1999, does not include long chain omega-3 polyunsaturated fatty acid (LC omega-3 PUFA) data. Measurement of the fatty acid content of diets initially analysed using AUSNUT1999 requires conversion to AUSNUT2007, an updated database inclusive of LC omega-3 PUFA. The aim of this study was to convert clinical trial dietary data from AUSNUT1999 to AUSNUT2007 and measure LC omega-3 PUFA intake. Clinical trial diet history (DH) data was converted from AUSNUT1999 to 2007 using a staged approach. Macronutrient intake from AUSNUT1999 and 2007 were calculated and compared via paired t-tests and Wilcoxon Signed Ranks tests. Mean …

Baseline Characteristics Associated With Different Bmi Trajectories In Weight Loss Trials: A Case For Better Targeting Of Interventions, Marijka Batterham, Linda C. Tapsell, Karen E. Charlton Nov 2015

Baseline Characteristics Associated With Different Bmi Trajectories In Weight Loss Trials: A Case For Better Targeting Of Interventions, Marijka Batterham, Linda C. Tapsell, Karen E. Charlton

Dr Marijka Batterham

Background/Objectives: Dietary weight loss interventions have heterogeneous outcomes in long-term studies, with many participants regaining part or all of the lost weight. Growth mixture modelling is a novel analytic approach that can be used to identify different trajectories of weight change during a trial rather than focussing on the total amount of weight lost. Subjects/Methods: Data were pooled from two 12-month dietary weight loss studies where no significant difference was detected between the treatment and control arms, thus allowing analysis independent of treatment. The data set included 231 subjects (74.5% female), with a mean weight loss of 6.40 kg (4.96). …
