Pathoecology Of Two Ancestral Pueblo Villages, Karl Reinhard

Karl Reinhard Publications

Pathoecology is the study of the biotic, abiotic, and cultural environments of disease (Martinson et al. 2003). A parasitic infection is the result of the pathoecological interaction of host behavior, parasite life cycle, the environment in which both life forms live, the nutritional status of the host, and host physiological responses to all of these factors. Parasites contribute to anemia in many ways. Some, such as hookworm, actually consume blood and cause iron loss through their activities. For other parasites, symptoms such as profuse diarrhea reduce intestinal absorption of nutrients. Others, such as certain fish tapeworms, actually compete for absorption …

Paleoparasitology: Perspectives With New Techniques, Adauto Araújo, Karl Reinhard, Otilio M. Bastos, Ligia C. Costa, Claude Pirmez, Alena Iñighez, Ana Carolina Vicente, Carlos M. Morel, Luiz Fernando Ferreira

Karl Reinhard Publications

Paleoparasitology is the study of parasites found in archaeological material. The development of this field of research began with histological identification of helminth eggs in mummy tissues, analysis of coprolites, and recently through molecular biology. An approach to the history of paleoparasitology is reviewed in this paper, with special reference to the studies of ancient DNA identified in archaeological material.

Paleoparasitologia é o estudo de parasitos encontrados em material arqueológico. O desenvolvimento deste campo da pesquisa teve início com a identificação de ovos de helmintos em tecidos mumificados, análise de coprólitos e, recentemente, através da …

Intravenous Nicotine Conditions A Place Preference In Rats Using An Unbiased Design, Jamie L. Wilkinson, Rick A. Bevins

Department of Psychology: Faculty Publications

The rewarding effects of nicotine contribute to the chronic use of tobacco products. The place conditioning task, a widely used pre-clinical model to study drug reward, has lead to mixed results in rats when nicotine was administered subcutaneously or intraperitoneally; intravenously administered nicotine has not been examined. Further, much of the research demonstrating a nicotine-conditioned place preference in rats has used a biased design making these results susceptible to nonreward interpretations. The present study assessed whether intravenous (IV) nicotine would condition a place preference in an unbiased design and evaluated important behavioral parameters: nicotine dose, number of conditioning trials, and …

Competition Between The Conditioned Rewarding Effects Of Cocaine And Novelty, Carmela M. Reichel, Rick A. Bevins

Department of Psychology: Faculty Publications

Access to novelty might provide an alternative learning history that competes with conditioned drug reward. We tested this suggestion in rats using a place conditioning procedure with cocaine and novelty. In Experiment 1, rats were conditioned with cocaine to prefer one side of an apparatus. In a subsequent phase, cocaine exposure continued; however, on the unpaired side, separate group of rats had access to novel objects, cocaine injections, or saline with no objects. Pairings with novel objects or cocaine shifted a preference away from the cocaine-paired environment during drug-free and drug-challenge tests. Experiment 2 tested novelty’s impact when cocaine exposure …

Basic And Applied Issues In Eyewitness Research: A Münsterberg Centennial Retrospective, Brian H. Bornstein, Christian Meissner

Department of Psychology: Faculty Publications

Whether memory research should emphasize fundamental psychological theory in well-controlled laboratory settings (i.e. “basic” research) or practical questions in naturalistic settings (i.e. “applied” research) is a recurrent question in the field. The debate became especially prominent with the advent of the “everyday memory movement” in the 1980s (e.g. Banaji & Crowder, 1989; Neisser, 1978, 1991), but it dates back to the origins of experimental psychology itself (i.e. the basic approach espoused by Wundt and Titchener vs. the more applied perspective taken by Külpe, Ebbinghaus, Binet, James and others). The debate is particularly relevant to the subarea of eyewitness memory, which …

Crisis, What Crisis? Perception And Reality In Civil Justice, Brian H. Bornstein, Timothy R. Robicheaux

Department of Psychology: Faculty Publications

"Excessive litigation has created a crisis in America," according to an article on the Alexandria, Virginia-based Center for Individual Freedom’s website (Marcus, 2004).
This article was the first of 63,100 links retrieved in a February 16, 2007, Google.com search for the words ‘‘litigation crisis,’’ and a search for the word ‘‘tort reform’’ on the same day returned over a million results. Not every linked article was as bold about the current ‘‘litigation crisis’’ in the United States, and not every linked article promoted a need for tort reform, but the search demonstrates the current salience of these issues in the …

Parenting Styles And Youth Well-Being Across Immigrant Generations, Anne Driscoll, Stephen Russell, Lisa J. Crockett

Department of Psychology: Faculty Publications

This study examines generational patterns of parenting styles, the relationships between parenting styles and adolescent well-being among youth of Mexican origin, and the role of generational parenting style patterns in explaining generational patterns in youth behavior (delinquency and alcohol problems) and psychological well-being (depression and self-esteem). This study uses two waves of data from the National Longitudinal Study of Adolescent Health (Add Health). The proportion of teens with permissive parents increased with generation; other parenting styles declined. The rate of youth with behavioral problems increased with generation. Self-esteem improved with generation; depression scores did not. Bivariate generational patterns of behavioral …

Cue-Elicited Negative Affect In Impulsive Smokers, Neal Doran, Jessica Werth Cook, Dennis E. Mcchargue, Mark G. Myers, Bonnie Spring

Department of Psychology: Faculty Publications

Impulsivity is associated with cigarette smoking, but the nature of this relationship and the mechanisms that maintain it are relatively unknown. The relationship has often been thought to reflect appetitive processes, but research suggests that an affective pathway exists as well. The present study tested the effect of impulsivity on affective responses to an environmental smoking cue. Adult smokers (N = 62) were exposed to a neutral cue and a smoking cue in separate experimental sessions in a repeated measures design. Mixed-effects regression analyses showed that larger postexposure increases in negative affect were associated with high scores on 2 facets …

Forgetting The Once-Seen Face: Estimating The Strength Of An Eyewitness’S Memory Representation, Kenneth A. Deffenbacher, Brian H. Bornstein, E. Kiernan Mcgorty, Steven D. Penrod

Department of Psychology: Faculty Publications

The fidelity of an eyewitness’s memory representation is an issue of paramount forensic concern. Psychological science has been un¬able to offer more than vague generalities concerning the relation of retention interval to memory trace strength for the once-seen face. A meta-analysis of 53 facial memory studies produced a highly reliable association (r = .18, d = 0.37) between longer retention intervals and positive forgetting of once-seen faces, an effect equally strong for both face recognition and eyewitness identification studies. W. A. Wick¬elgren’s (1974, 1975, 1977) theory of recognition memory provided statistically satisfactory fits to 11 different empirical forgetting func¬tions. Applied …

Procedural Justice In Family Conflict Resolution And Deviant Peer Group Involvement Among Adolescents: The Mediating Influence Of Peer Conflict, Jennifer Stuart, Mark Fondarco, Scott A. Miller, Veda Brown, Eve M. Brank

Department of Psychology: Faculty Publications

The involvement of adolescents with deviant peer groups is one of the strongest proximal correlates to juvenile delinquency and stems from a variety of causes. Past research has linked ineffective parenting with peer variables, including deviant peer group involvement and peer conflict during adolescence. In this study, adolescents’ appraisals of procedural justice within the family (adolescents’ appraisals of how fairly they are treated by parents in the process of resolving family conflict) were examined as one aspect of effective parenting that may relate to deviant peer group involvement in early adolescence. Data from 1660 middle school students (ages 11-14, mean …

Role Of Affective Associations In The Planning And Habit Systems Of Decision-Making Related To Addiction, Marc T. Kiviniemi, Rick A. Bevins

Department of Psychology: Faculty Publications

The model proposed by Redish et al. considers vulnerabilities within decision systems based on expectancy-value assumptions. Further understanding of processes leading to addiction can be gained by considering other inputs to decision-making, particularly affective associations with behaviors. This consideration suggests additional decision-making vulnerabilities that might explain addictive behaviors.

A Longitudinal Examination Of The Bidirectional Links Between Academic Achievement And Parent-Adolescent Conflict, Aryn M. Dotterer, Lesa Hoffman, Ann C, Crouter, Susan M. Mchale

Department of Psychology: Faculty Publications

We examined reciprocal associations between parent-adolescent conflict and academic achievement over a 2-year period. Participants were mothers, fathers, and adolescents from predominantly White, working and middle class families (N = 168). After accounting for previous academic achievement, parent-adolescent conflict predicted relative declines in academic achievement 2 years later. After controlling for relationship quality at Time 1, lower math grades predicted relative increases in parent-adolescent conflict 2 years later among families with less education.

Generalizing The Dynamic Field Theory Of Spatial Cognition Across Real And Developmental Time Scales, Vanessa R. Simmering, John P. Spencer, Anne R. Schutte

Department of Psychology: Faculty Publications

Within cognitive neuroscience, computational models are designed to provide insights into the organization of behavior while adhering to neural principles. These models should provide sufficient specificity to generate novel predictions while maintaining the generality needed to capture behavior across tasks and/or time scales. This paper presents one such model, the Dynamic Field Theory (DFT) of spatial cognition, showing new simulations that provide a demonstration proof that the theory generalizes across developmental changes in performance in four tasks—the Piagetian A-not-B task, a sandbox version of the A-not-B task, a canonical spatial recall task, and a position discrimination task. Model simulations demonstrate …

Patience, Jeffrey R. Stevens, David W. Stephens

Department of Psychology: Faculty Publications

What is patience? Humans and other animals often make decisions that trade off present and future benefits. Should a monkey eat an unripe fruit or wait for it to ripen? Should I purchase the iPhone at its debut or wait for the price to drop in a few months? In these dilemmas, large gains often require long waits, so decision makers must choose between a smaller, sooner reward and a larger, later reward.

It sometimes makes sense to choose the smaller, sooner alternative, for example in a very rich environment, but in many natural situations, waiting for the larger, later …

Individual Decision Making And The Evolutionary Roots Of Institutions, Richard Mcelreath, Robert Boyd, Gerd Gigerenzer, Andreas Glöckner, Peter Hammerstein, Robert Kurzban, Stefan Magen, Peter J. Richerson, Arthur Robson, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

Just as many aspects of individual decisions are sometimes called "unconscious" or "automatic," we know that some institutions have evolved through "unconscious," nondeliberative mechanisms. Their function can also be largely nondeliberative, as in the case of some institutions that may structure behavior without requiring any reflection on the part of the participants. On the other hand, political institutions exist for the purpose of bringing deliberative mechanisms to bear on institutions in the hope of changing them for the better. The immense project of building an integrated explanation of institutions from individual brains to nations-has only barely begun. In this chapter, …

A Fruit In The Hand Or Two In The Bush? Divergent Risk Preferences In Chimpanzees And Bonobos, Sarah R. Heilbronner, Alexandra G. Rosati, Jeffrey R. Stevens, Brian Hare, Marc D. Hauser

Department of Psychology: Faculty Publications

Human and non-human animals tend to avoid risky prospects. If such patterns of economic choice are adaptive, risk preferences should reflect the typical decision-making environments faced by organisms. However, this approach has not been widely used to examine the risk sensitivity in closely related species with different ecologies. Here, we experimentally examined risk-sensitive behavior in chimpanzees (Pan troglodytes) and bonobos (Pan paniscus), closely related species whose distinct ecologies are thought to be the major selective force shaping their unique behavioral repertoires. Because chimpanzees exploit riskier food sources in the wild, we predicted that they would exhibit …

Getting Ready: Promoting School Readiness Through A Relationship-Based Partnership Model, Susan M. Sheridan, Christine Marvin, Lisa Knoche, Carolyn P. Edwards

Department of Psychology: Faculty Publications

School readiness is determined by the life experiences of young children between birth and enrollment in formal education programs. Early intervention and education programs designed to promote school readiness often focus on skills a child fails to demonstrate that are believed to be of importance to social and academic success. The Getting Ready model of early childhood intervention (Sheridan, Edwards, & Knoche, 2003) recognizes the transactional nature of young children’s development and the important role parents play in pre-school readiness and school-age success. In the Getting Ready model, collaborative partnerships between parents and professionals are encouraged to promote parent’s competence …

Predictors Of Goggle Use Among Racquetball Players, Carmen P. Mclean, David K. Dilillo, Brian H. Bornstein, R. V. Bevini

Department of Psychology: Faculty Publications

Racquetball is a popular, high-intensity competitive sport that requires quick reflexes and keen spatial awareness. Players may be vulnerable to eye injuries, which could be prevented through use of proper protective eyewear (Feigelman, Sugar, Jednock, Read, & Johnson, 1983). Given the low rates of goggle use among squash players (Eime, Owen, & Finch, 2004), the use of goggles among racquetball players is suspected to be low. However, to date there have been no studies investigating predictors of goggle use in racquetball players. Understanding the rates and predictors of goggle use among racquetball players is an important prerequisite to developing effective …

Willingness And Ability To Pay For Artemisinin-Based Combination Therapy In Rural Tanzania, E.C. Saulo, B.C. Forsberg, Zul Premji, S.M. Montgomery, A. Bjorkman

Pathology, East Africa

Background: The aim of this study was to analyse willingness to pay (WTP) and ability to pay (ATP) for ACT for children below five years of age in a rural setting in Tanzania before the introduction of artemisinin-based combination therapy (ACT) as first-line treatment for uncomplicated malaria. Socio-economic factors associated with WTP and expectations on anti-malaria drugs, including ACT, were also explored.

Methods: Structured interviews and focus group discussions were held with mothers, household heads, health-care workers and village leaders in Ishozi, Gera and Ishunju wards in north-west Tanzania in 2004. Contingent valuation method (CVM) was used with "take-it-or-leave- it" …

Enterobius Vermicularis Ancient Dna In Pre-Columbian Human Populations, Alena Mayo Iniguez, Karl J. Reinhard, Luiz Fernando Ferreira, Adauto Araujo, Ana Carolina, Paulo Vincente

Karl Reinhard Publications

In prehistoric populations the paleoparasitological findings show an Enterobius vennicularis homogeneous distribution among North American hunter-gatherers intensified with the advent of agriculture. The same occurred in the transition from nomad hunter-gatherers to sedentary farmers in South America, although E. vermicularis infection encompasses only the ancient Andean peoples. Since molecular techniques are sensitive in detecting ancient DNA (aDNA), in this work we have performed a molecular paleoparasitological study of E. vermicularis. aDNA was recovered from North and South American coprolites (4110 BC-AD 900). Human (cox 2 and HVR) and pinworm (5S rRNA spacer) sequences were determined. The sequence analysis confirmed E. …

Academic Incentives Impact On Increasing Seventh -Graders Physical Activity During Leisure Time, Jeffrey Scott Brinker

Walden Dissertations and Doctoral Studies

Recent research clearly demonstrates that a decrease of physical activity has occurred among young people. Hence, the purpose of this study was to examine the impact of external motivation on physical activity. Drawn from self-determination theory, the specific research question examined if academic incentives effectively motivated 7th grade students to participate in a 3-week fitness program. A quasi-experimental pre-post design examined treatment and control groups drawn from a sample of 24 students from three physical education classes. The treatment group received academic incentives whereas the control group received no external incentives but were asked to complete the same fitness Program. …

Implementing A Forensic Educational Package For Registered Nurses In Two Emergency Departments In Western Australia, Christine M. Michel

Theses

The results of violence are a major public health problem that infiltrates hospital emergency departments (ED) daily. Often, ED nurses are the first healthcare professionals to see patients, speak with family members, handle personal property and collect laboratory specimens. Such actions can be of extreme importance to the 27 different categories of forensic patients. To adequately address forensic patient issues, ED nurses need exposure to forensic education. The aim of this research was to develop and evaluate the effectiveness of a clinical forensic education package on ED nurses’ perceptions, knowledge and care of forensic patients. To accomplish this aim, this …

Where's The Kale? Environmental Availability Of Fruits And Vegetables In Two Racially Dissimilar Communities, Edith M. Williams, Bamidele O. Tayo, Beverly Mclean, Ellen Smit, Christopher T. Sempos, Carlos J. Crespo

Faculty Publications

Minority communities across the United States have limited numbers of stores that offer a variety of fruits and vegetables, creating major barriers to good eating habits and nutritional practices among minority groups such as African Americans. Factors like environmental availability of healthy food options have not been fully investigated as possible sources of current cross-population differences in disease. The present study examined whether a predominantly African American neighborhood had disproportionately less availability of fruits and vegetables than a predominantly non-Hispanic White neighborhood. Availability was judged on the bases of the types of stores available in each community and the specific …

Polymorphisms In Methionine Synthase, Methionine Synthase Reductase And Serine Hydroxymethyltransferase, Folate And Alcohol Intake, And Colon Cancer Risk, Susan E. Steck, Temitope O. Keku, Lesley M. Butler, Joseph Galanko, Beri Massa, Robert C. Millikan, Robert S. Sandler

Faculty Publications

Background/Aims - We examined associations among folate and alcohol intake, SNPs in genes involved in one-carbon metabolism and colon cancer risk.

Methods - Colon cancer cases (294 African Americans and 349 whites) were frequency matched to population controls (437 African Americans and 611 whites) by age, race and sex from 33 North Carolina counties from 1996 to 2000. Folate and alcohol intakes were collected by dietary interview. Five SNPs were genotyped using DNA from whole blood: SHMT C1420T; MTRR A66G; MTR A2756G, and the previously-reported MTHFR C677T and MTHFR A1298C. Adjusted odds ratios (OR) and 95% …

Use Of Accelerometers In A Large Field-Based Study Of Children: Protocols, Design Issues, And Effects On Precision, Calum Mattocks, Andy R. Ness, Sam D. Leary, Kate Tilling, Steven N. Blair, Julian Shield, Kevin Deere, Joanne Saunders, Joanne Krikby, George Davey Smith, Jonathan Wells, Nicholas Wareham, John J. Reilly, Chris J. Riddoch

Faculty Publications

Background: Objective methods can improve accuracy of physical activity measurement in field studies but uncertainties remain about their use.

Methods: Children age 11 years from the Avon Longitudinal Study of Parents and Children (ALSPAC), were asked to wear a uni-axial accelerometer (MTI Actigraph) for 7 days.

Results: Of 7159 children who attended for assessment, 5595 (78%) provided valid measures. The reliability coefficient for 3 days of recording was .7 and the power to detect a difference of 0.07 SDs (P ≤ .05) was > 90%. Measures tended to be higher on the first day of recording (17 counts/min; 95% CI, …

Physical Activity And Blood Pressure In Childhood: Findings From A Population-Based Study, Sam D. Leary, Andy R. Ness, George Davey Smith, Calum Mattocks, Kevin Deere, Steven N. Blair, Chris J. Riddoch

Faculty Publications

The pathological processes associated with development of cardiovascular disease begin early in life. For example, elevated blood pressure (BP) can be seen in childhood and tracks into adulthood. The relationship between physical activity (PA) and BP in adults is well-established, but findings in children have been inconsistent, with few studies measuring PA mechanically. Children aged 11 to 12 years were recruited from the Avon Longitudinal Study of Parents and Children. 5505 had systolic and diastolic BP measurements, plus valid (at least 10 hours for at least 3 days) accelerometer measures of PA; total PA recorded as average counts per minute …

Gender And Apologies: Exploring Offended Females' Perceptions Of Apologies From Males And Females, Stacey Bennet

Theses : Honours

The construct of apology has recently received more attention by researchers (Allan, 2007) and several factors that may influence apologetic responses have been identified. The gender of an offender is one such factor. A review was undertaken to examine the literature pertaining to the influence of the gender of an offender on apologies. As a result of the review, several themes were identified. These included gender differences and similarities in the frequency of apologies, the quantity and complexity of components, and the actual content of those components. Furthermore, contextual factors that may play a role in the influence of gender …

A Study Of Compliance In Aged Care Facilities With Regards To Australian Standards 1851:2006 Maintenance Of Fire Protection Systems And Equipment Section 17, Robert Doleman

Theses : Honours

The management of risk within a nursing home environment is widely viewed as an undertaking perfom1ed by the owners or managers of nursing homes. The residents of these homes are reliant upon the owners and managers to keep them safe, due in part to a traditional belief that they are the experts and have a greater understanding of risk. To establish risk it is first a requirement to have an understanding of levels of risk and risk management techniques. Risk appreciation is often influenced by heuristic representativeness, as well as social and cultural influences. The higher level of risk within …

Influence De La Charge De Travail Sur Les Indicateurs Biologiques D'Exposition De Cinq Solvants, Robert Tardif, Ginette Charest-Tardif, Ginette Truchon, Martin Brochu

Rapports de recherche scientifique

Plusieurs facteurs qui sont susceptibles d’exercer un impact majeur sur le comportement des contaminants dans l’organisme des individus exposés. À cet égard, la ventilation alvéolaire joue un rôle particulièrement important puisqu’elle est directement influencée par l’intensité de l’activité physique ou de la charge de travail. Or toute augmentation de cette charge de travail se traduit par une augmentation de la ventilation alvéolaire laquelle dépend de la fréquence respiratoire et du volume courant. Selon les produits en cause, ces modifications physiologiques peuvent avoir des répercussions importantes sur les quantités de contaminants absorbées et sur leur élimination, et par conséquent, sur leurs …
