Protecting Your Back: Weight Room Management, Peter Titlebaum, Gordon Rackley

Peter J. Titlebaum

Weight room supervision can be a formidable undertaking without the necessary preparations and precautions. Weight room supervisors are much like the Secret Service; that is, no matter what happens, if bad, it is the supervisor's fault. Risk management is more important now than at any point in history. The keys to preventing problems and creating an efficient weight room facility include a highly trained staff and a thoroughly detailed employee manual designed specifically for the weight room.

Hazing: What Ohio High School Teachers, Coaches And Administrators Need To Know, Corinne Daprano, Meghan Kenney, Peter Titlebaum, Michael Triola

Peter J. Titlebaum

Once thought to be primarily an issue of concern for university fraternities and sororities, hazing has emerged as a disturbing trend with an increase in the number of incidents involving high school student athletes. High school coaches, athletic administrators, and teachers must understand that initiation rites of sport teams can sometimes spiral out of control with grave legal and financial consequences for student athletes and school officials. The purposes of this article are to:

• Define hazing and review the history of anti-hazing legislation in the United States of America.

• Describe hazing laws in the State of Ohio.

Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell

Howard Casey Cromwell

Polychlorinated biphenyl (PCB) is a persistent organic pollutant known to induce diverse molecular and behavioral alterations. Effects of PCB exposure could be transmitted to future generations via changes in behavior and gene expression. Previous work has shown that PCB-exposure can alter social behavior. The present study extends this work by examining a possible molecular mechanism for these changes. Pregnant rats (Sprague-Dawley) were exposed through diet to a combination of non-coplanar (PCB 47 - 2,20,4,40-tetrachlorobiphenyl) and coplanar (PCB 77 - 3,30,4,40- tetrachlorobiphenyl) congeners. Maternal care behaviors were examined by evaluating the rate and quality of nest building on the last 4 …

Individual Characteristics And Their Effect On Predicting Mu Rhythm Modulation, Adriane Randolph, Melody Jackson, Saurav Karmakar

Adriane B. Randolph

Brain-computer interfaces (BCIs) offer users with severe motor disabilities a nonmuscular input channel for communication and control but require that users achieve a level of literacy and be able to harness their appropriate electrophysiological responses for effective use of the interface. There is currently no formalized process for determining a user's aptitude for control of various BCIs without testing on an actual system. This study presents how basic information captured about users may be used to predict modulation of mu rhythms, electrical variations in the motor cortex region of the brain that may be used for control of a BCI. …

Connecting Through Consilience: Ecology, Society, Culture And Technology, Ruth Mirams, Alexander Hayes

Alexander Hayes Mr.

Amongst linguistic, cultural and geographic diversity, humanity is characterised by inquisitiveness, communication and a deep desire to connect with each other. Despite our advanced intelligence and technological capacity, we are creatures of nature - a species which occupies a habitat, depends on consumable resources and fragile in many ways. As a species, we currently face challenges including overpopulation, diminishing resources and habitat degradation. In essence, we are exhausting the resources we depend on. [1] Resource depletion, disruption, famine, growth and sustainability are all observable in other species and natural systems. Human societies and systems can be described through the same …

Willingness To Pay For Flood And Ecological Risk Reduction In An Urban Watershed, David Clark, Diane Novotny, Robert Griffin, Douglas Booth, Alena Bartosova, M Hutchinson

Robert Griffin

Urban watershed managers frequently must address alternative policy goals; flood control and ecological risk reduction. This study combines hydrologic models of flood control and biotic models of ecologic risk with economic models of willingness-to-pay and psychological models of risk processing and planned behavior to evaluate these two alternative policy objectives. The findings reveal that flood risk exposure, especially for those individuals who would remain outside the 100 year flood plain if the project were enacted, does influence the financial support that local residents would be willing to make to a flood control project. Other important determinants include demographic factors such …

Stratigraphic Distribution And Suggested Evolution Of Dendroid Graptolites From The Silurian Of Eastern Australia, Barrie Rickards, Anthony Wright

Anthony Wright

Five evolutionary lineages are proposed for Silurian species of the benthic dendroid graptolite genus Dictyonema, based largely on the exceptional eastern Australian records of the genus, comprising at least 25 species. These are: A, the delicatulum lineage with bifurcating ventral autothecal apertural spines; B, the paululum lineage with single ventral apertural spines or processes; C, the elegans lineage with isolated thecal apertures ± processes; D, the sherrardae lineage with dorsal apertural processes; and E, the venustum lineage with simple autothecal apertures. Brief comments are also made on other dendroid genera occurring in Australian strata, namely: Acanthograptus, Koremagraptus, Callograptus, Dendrograptus, Stelechocladia, …

Digitization Of Herbarium Specimens, A Collaborative Process, Lawrence Schmidt

Larry O Schmidt

Digital collections in museums, libraries, and other agencies are expanding rapidly. Digitization of books, maps, photographs, and other objects for both preservation and dissemination are changing the way libraries work. Librarians who have, historically, worked with collections in print formats are anxious to move toward digital content as the wave of the future. Rather than stand on the sidelines and watch as the digital movement passes by, librarians need to be proactive and create digital content using both collections within the libraries’ walls and proactively seek opportunities to work collaboratively with stakeholders outside of the libraries’ hallowed halls. The creation …

Educational Data Mining: An Advance For Intelligent Systems In Education, Ryan Baker

Ryan S.J.d. Baker

Computer-based technologies have transformed the way we live, work, socialize, play, and learn. Today, the use of data collected through these technologies is supporting a second-round of transformation in all of these areas. Over the last decades, the methods of data mining and analytics have transformed field after field. Scientific fields such as physics, biology, and climate science have leveraged these methods to manage and make discoveries in previously unimaginably large datasets. The first journal devoted to data mining and analytics methods in biology, Computers in Biology and Medicine, began publication as long ago as the 1970s. In the mid-1990s …

Effects Of Polychlorinated Biphenyl (Pcb) On Response Perseveration And Ultrasonic Vocalization Emission In Rat During Development, Howard Cromwell

Howard Casey Cromwell

The 3 major symptoms of autistic spectrum disorders include 1) social behavioral alterations, 2) problems in communication and 3) higher-order motoric deficits of perseveration and stereotyped movements. Previous work has shown that early developmental exposure to polychlorinated biphenyls (PCBs) alters rat pup social motivation and juvenile rat social recognition/investigation. The present work extends this previous research by examining how perinatal PCB exposure alters motoric functions and communication abilities at different stages of development. Action perseveration was examined using performance measures from a T-maze environment. Communication abilities were evaluated by monitoring ultrasound emission in rat pups during a brief isolation from …

Synthesis Of Novel Sugar Diamino Acids, M Thillakan, A Katsifis, D Skropeta

Danielle Skropeta

Sugar amino acids (SAAs) are found in nature as good construction elements for the preparation of peptide mimetics and oiigosaccharides in drug design and development. The synthesis of SAAs is readily accomplished in few steps and more than 40 SAAs have been synthesised to date.2 Sugar amino acids with an additional amino group, the sugar diamino acid (SDAs) would represent a useful expansion to the library of SAAs available because one of the amino group and carboxylic acid is available for peptide coupling and the another amino/azide group allow to do further derivatisation via peptide or click chemistry such as …

Valuing Water: Variability And The Lake Eyre Basin, Central Australia, Leah Gibbs

Leah Maree Gibbs

'Environmental values' form an increasingly important component of natural resource management, but use of the term 'value' is dominated by a narrow and limiting utility-based definition. In this paper I consider theories of value and practices of valuing water in the arid and semi-arid Lake Eyre Basin, central Australia. While value is the subject of diverse meanings - both within a range of academic disciplines and as understood by people in specific places - methods of valuing water in natural resource management are limited by reductionism, anthropocentrism and cultural specificity. This conceptualisation of value does not adequately capture what people …

Parcel Subdivision Automation For Agent-Based Land Use Modelling, Rohan Wickramasuriya, Laurie Chisholm, Marji Puotinen, Nicholas Gill, Peter Klepeis

Rohan Wickramasuriya, Ph.D.

To a significant extent rural Australia is transforming into multifunctional landscapes. Amenity migration (i.e. movement of people from metropolitan to rural settings) is a major driving force of this transition in many areas. However, the effects of amenity migration on the receiving landscapes are not yet fully understood. Agent-based land use modelling helps unravel the complex spatio-temporal relationships that affect landscape response to change from amenity migration. A land subdivision module is essential for a complete agent-based land use model developed for these landscapes because the land sold to in-migrants are lots that are subdivided from much larger tracts. In …

Fibre: Male Participants Not Getting Enough, Rebecca Thorne, Jane O'Shea, Qingsheng Zhang, Linda Tapsell, Marijka Batterham, Karen Charlton

Qingsheng Zhang

A regular intake of dietary fibre has been associated with a number of health benefits. Consuming a high fibre diet may significantly lower the risk of developing heart disease, stroke, hypertension, diabetes and obesity (Anderson et al, 2009). Foods high in fibre such as fruit, vegetables, legumes and wholegrains are regularly included in diets targeting weight loss as they are low in fat, sugar and salt and contain a number of vitamins and minerals. Participants in trials using healthy background diets may increase their fibre intake in addition to the study variables. The aim of this study was to report …

Start Date May Predict Attrition 6 Months Into A 12mth Dietary Intervention Weight Loss Trial, Jane O'Shea, Linda Tapsell, Marijka Batterham, Karen Charlton, Yasmine Probst, Rebecca Thorne, Qingsheng Zhang, Holley Jones

Qingsheng Zhang

Participant recruitment is a difficult and time consuming aspect of clinical trials, often resulting in delays and budget overruns. Having reached recruitment targets the next challenge is participant retention. Some weight-loss studies have attrition rates around 60% which may introduce bias in the results. It may be possible to reduce attrition rates if known predictors can be found but to date few studies produced consistent results. The aim of this exploratory study was to determine whether start date could be a predictor of attrition for participants involved in the SMART weight loss clinical trial (ACTRN12608000425392). Recruitment for the trial occurred …

Pork, Beef And Chicken Have Similar Effects On Acute Satiety And Hormonal Markers Of Appetite, Karen Charlton, Linda Tapsell, Marijka Batterham, Rebecca Thorne, Jane O'Shea, Qingsheng Zhang, Eleanor Beck

Qingsheng Zhang

The effects of three different meat-containing breakfast meals (pork, beef or chicken) on acute satiety and appetite regulatory hormones were compared using a within-subjects study design. Thirty fasting non-smoking pre-menopausal women attended a research centre on three test days to consume, a meat-containing meal matched in energy (kJ) and protein content, palatability, and appearance. No difference was found between meat groups for either energy intake or macronutrient profile of food consume data subsequent ad libitum buffet lunch, or over the rest of the day. Visual Analogue Scale(VAS) ratings for hunger and satiety over an 180min period did not differ between …

Online Advertising: Examining The Content And Messages Within Websites Targeted At Children, Lisa Kervin, Sandra Jones, Jessica Mantei

Jessica Mantei

It is recognised that from a young age children spend considerable portions of their leisure time on the Internet. In Australia a number of child-targeted magazines have associated websites, which have high and ever-increasing readership. We do not yet know the impact of this medium upon children. Overt advertising is evident on webpages, but so too are hidden advertisements in the written text, images and games. This material usually does not comply with existing broadcasting codes of practice for mainstream advertising. This article examines the instances of overt and covert advertisements for food within three websites monitored over a 12-month …

Late Quaternary Aeolian And Fluvial Interactions On The Cooper Creek Fan And The Association Between Linear And Source-Bordering Dunes, Strzelecki Desert, Australia, Timothy Cohen, Gerald Nanson, Joshua Larsen, B. Jones, David Price, Maria Coleman, Tim Pietsch

B. G. Jones

The Innamincka Dome and associated low-gradient fan in the Strzelecki Desert is the product of Cenozoic crustal warping that has aided formation of an extensive array of palaeochannels, source-bordering transverse dunes and superimposed linear dunes. These dunes have impeded the course of Cooper Creek and provided a repository of evidence for Quaternary climate change as well as the interactive processes between transverse and linear dune formation. At Turra, Gidgealpa and sites nearby are extensive fluvial and aeolian sand bodies that date from marine isotope stages (MIS) 8-3 and the Last Glacial Maximum (LGM) and are now surrounded or buried by …

This qualitative study targeted a sample of nine after-school program providers in London, Ontario. Data was collected via in-depth interviews and a demographic survey between January and April 2009. Strategies to enhance data trustworthiness were incorporated throughout. After-school program providers identified insufficient healthy eating curriculum and requested interactive, …

Structural Characterization Of Clusterin-Chaperone Client Protein Complexes, Amy Wyatt, Justin Yerbury, Mark Wilson

Mark R Wilson

Clusterin (CLU) is a potent extracellular chaperone that inhibits protein aggregation and precipitation otherwise caused by physical or chemical stresses (e.g. heat, reduction). This action involves CLU forming soluble high molecular weight (HMW) complexes with the client protein. Other than their unquantified large size, the physical characteristics of these complexes were previously unknown. In this study, HMW CLU-citrate synthase (CS), HMW CLU-fibrinogen (FGN), and HMW CLU-glutathione S-transferase (GST) complexes were generated in vitro, and their structures studied using size exclusion chromatography (SEC), ELISA, SDS-PAGE, dynamic light scattering (DLS), bisANS fluorescence, and circular dichroism spectrophotometry (CD). Densitometry of …

Communication: New Insight Into The Barrier Governing Co2 Formation From Oh + Co, Christopher Johnson, Berwyck Poad, Ben Shen, Robert Continetti

Berwyck L. J. Poad

Despite its relative simplicity, the role of tunneling in the reaction OH + CO → H + CO(2) has eluded the quantitative predictive powers of theoretical reaction dynamics. In this study a one-dimensional effective barrier to the formation of H + CO(2) from the HOCO intermediate is directly extracted from dissociative photodetachment experiments on HOCO and DOCO. Comparison of this barrier to a computed minimum-energy barrier shows that tunneling deviates significantly from the calculated minimum-energy pathway, predicting product internal energy distributions that match those found in the experiment and tunneling lifetimes short enough to contribute significantly to the overall reaction. …
