Effects Of Ice Hockey Facial Protectors On The Response Time And Kinematics In Goal-Directed Tasks, P M. Dowler, D J. Pearsall, P J. Stapley

Faculty of Health and Behavioural Sciences - Papers (Archive)

Ice hockey facial protectors are essential to prevent eye (and, in some cases, dental) injuries but must also not encumber vision and, in turn, playersapos; performance. The purpose of this study was to investigate the effects of three different facial protection conditions on temporal and kinematic parameters in a goal-directed pointing task: helmet (control), visor, and cage. Start and end target switches captured temporal estimates (reaction time (RT), movement time, (MT), and response time (RT+MT)), while a 13-light target array and 6-camera Vicon Mx system were used to collect upper-body kinematics data (head and thorax orientation, shoulder and elbow joint …

Erps And The Evoked Cardiac Response To Auditory Stimuli: Intensity And Cognitive Load Effects, Robert J. Barry, Carlie Lawrence

Faculty of Health and Behavioural Sciences - Papers (Archive)

The evoked cardiac response (ECR) may be described as the sum of two independent response components: an initial HR deceleration (ECR1), and a slightly later acceleration (ECR2), hypothesized to reflect stimulus registration and cognitive processing load, respectively. This study investigated processing load effects in the ECR and the event-related potential (ERP). Stimulus intensity was varied within subjects, and cognitive load was varied between subjects, in a counting/no counting task with a long interstimulus interval. The ECR showed a significant effect of counting, but not intensity. ERPs showed the expected obligatory processing effects in the N1, and substantial effects of cognitive …

Effect Of High Amylose Maize Starches On Colonic Fermentation And Apoptotic Response To Dna-Damage In The Colon Of Rats, Ian L. Brown, Richard K. Le Leu, Graeme P. Young, Ying Hu

Faculty of Health and Behavioural Sciences - Papers (Archive)

Background

We investigated in rats the effects of feeding different forms of high amylose maize starches (HAMS) rich in resistant starch (RS) to understand what the implications of RS heterogeneity might be for colonic biology, including innate cellular responses to DNA-damage.

Methods

A range of maize starches were compared: digestible cornstarch (Control), HYLON^® VII, Hi-maize^® 1043, Hi-maize^® 240, Hi-maize^® 260 and NOVELOSE^® 330. Included in the comparison was Cellulose. End-points after 4 weeks included: pH, short chain fatty acids (SCFA) levels, colonic epithelial cell kinetics and apoptotic response to carcinogen 'azoxymethane' in the colonic epithelium. …

Response Style Contamination Of Student Evaluation Data, Sara Dolnicar, Bettina Grun

Faculty of Commerce - Papers (Archive)

Student evaluation surveys provide instructors with feedback regarding development opportunities and they form the basis of promotion and tenure decisions. Student evaluations have been extensively studied, but one dimension hitherto neglected is the actual measurement aspect: which questions to ask, how to ask them, and what answer options to offer to students to get the most valid results. This study investigates whether cross-cultural response styles affect the validity of student evaluations. If they do, then the student mix in a class can affect an instructor's evaluation, potentially producing biased feedback and prompting inappropriate decisions by university committees. This article discusses …

Sex-Specific Developmental Plasticity In Response To Yolk Corticosterone In An Oviparous Lizard, Tobias O. Uller, Johan Hollander, Lee Astheimer, Mats M. Olsson

Faculty of Science - Papers (Archive)

Corticosterone exposure during prenatal development as a result of maternal upregulation of circulating hormone levels has been shown to have effects on offspring development in mammals. Corticosterone has also been documented in egg yolk in oviparous vertebrates, but the extent to which this influences phenotypic development is less studied. We show that maternal corticosterone is transferred to egg yolk in an oviparous lizard (the mallee dragon, Ctenophorus fordi Storr), with significant variation among clutches in hormone levels. Experimental elevation of yolk corticosterone did not affect hatching success, incubation period or offspring sex ratio. However, corticosterone did have a sex-specific effect …

Predicting The Response Of Coastal Wetlands Of Southeastern Australia To Sea-Level Rise, Kerrylee Rogers, Neil Saintilan

Faculty of Science, Medicine and Health - Papers: part A

Coastal saltmarsh is an endangered ecological community in New South Wales and sea-level rise has been listed as a key threatening process. Over the previous five decades moderate rates of sea-level rise have coincided with the invasion of saltmarsh by mangrove. Surface elevation tables (SETs) were installed in 12 coastal wetlands in Southeastern Australia to establish elevation and accretion trajectories for comparisons with mangrove encroachment of saltmarsh and sea-level rise. SETs confirmed that the elevational response of wetlands is more complex than accretion alone and elevation changes may also be attributed to below-ground processes that alter the soil volume such …

Assessing Alternative And Differential Response: Implications For Social Work Practice In Diverse Communities, Executive Summary, Jill Duerr Berrick, Christina Branom, Amy Conley Wright, Amy Price

Faculty of Social Sciences - Papers (Archive)

This study examines outcomes, processes, and community context for "Another Road to Safety" (ARS), a Differential Response intervention providing voluntary home visiting to families reported for child maltreatment. Using mixed methods and drawing on diverse data sources (including interviews, focus groups, administrative records, and census tract data), this research will examine implementation of the program model; clients' perspectives on services; preliminary client outcome data; and the impact of neighborhood factors on client outcomes. Findings will inform the development of a research-based curriculum that will facilitate skill-development in implementation, community engagement, and client understanding for Differential Response interventions.

Survey Response As Organisational Behaviour: An Analysis Of The Annual Enterprise Survey, 2003-2007, Walter R. Davis, Nathaniel Pihama

Faculty of Engineering and Information Sciences - Papers: Part A

Non-response is a matter of great concern to national statistical offices and a key issue for any survey because it can introduce bias to survey estimation. However, in this presentation, we focus on a business's decision to participate in a survey as an example of organisational behaviour and draw on basic organisational theory to explain why businesses may not respond to surveys (eg Tomaskovic-Devey et al 1994). The data are drawn from the Statistics New Zealand Respondent Management System, which links the response history of individual businesses in all Statistics NZ surveys with information from the Statistics NZ Business Frame. …
