Adherence To A Mediterranean Diet And Alzheimer's Disease Risk In An Australian Population, Samantha Gardener, Y Gu, Stephanie Rainey-Smith, J B Keogh, P M Clifton, S L Mathieson, Kevin Taddei, Alinda Mondal, Vanessa Ward, N Scarmeas, M Barnes, K Ellis, R Head, C 0 Masters, D Ames, S 0 Macaulay, C 0 Rowe, C Szoeke, Ralph Martins

Research outputs 2012

The Mediterranean diet (MeDi), due to its correlation with a low morbidity and mortality for many chronic diseases, has been widely recognised as a healthy eating model. We aimed to investigate, in a cross-sectional study, the association between adherence to a MeDi and risk for Alzheimer’s disease (AD) and mild cognitive impairment (MCI) in a large, elderly, Australian cohort. Subjects in the Australian Imaging, Biomarkers and Lifestyle Study of Ageing cohort (723 healthy controls (HC), 98 MCI and 149 AD participants) completed the Cancer Council of Victoria Food Frequency Questionnaire. Adherence to the MeDi (0- to 9-point scale with higher …

Fabry-Perot-Based Surface Plasmon Resonance Sensors, Feng Xiao, Guangyuan Li, Kamal Alameh, Anshi Xu

Research outputs 2012

A new sensing approach based on the use of an optical Fabry-Pérot (FP) cavity in conjunction with surface plasmon resonance (SPR) is proposed and theoretically investigated. The impact of the SPR on the intensity and phase response of the proposed sensor structure is evaluated using a modified FP model that takes into account the SPR effect. Compared to the conventional optical-phase-detection-based Kretschmann configuration, the proposed sensing approach requires only the measurement of the output power spectrum over a narrow wavelength span of several nanometers to evaluate the phase responses of the sensor, making it more attractive for practical high-sensitivity sensing …

Unidirectionally Optical Coupling From Free Space Into Silicon Waveguide With Wide Flat-Top Angular Efficiency, K Li, G Li, Feng Xiao, Fan Lu, Zhonghua Wang, A Xu

Research outputs 2012

A grating coupling scheme from free-space light into silicon waveguide with a remarkable property of wide flat-top angular efficiency is proposed and theoretically investigated. The coupling structure is composed of two cascaded gratings with a proper distance between their peak angular efficiencies. A quantitative semi-analytical theory based on coupled-mode models is developed for performance prediction and validated with the fully vectorial aperiodic Fourier modal method (a-FMM). With the theory, wide flat-top angular response is achieved and the conditions are pointed out. Proof-of-principle demonstrations show that the -1 dB angular widtha figure of merit to evaluate the flat-top performanceis broadened to …

Gaas Based Long-Wavelength Microring Resonator Optical Switches Utilising Bias Assisted Carrier-Injection Induced Refractive Index Change, S Ravindran, A Datta, Kamal Alameh, Yong Tak Lee

Research outputs 2012

We propose and analyse a GaAs-based optical switch having a ring resonator configuration which can switch optical telecommunication signals over the 1300 nm and 1500 nm bands, using bias assisted carrier injection as the switching mechanism. The switching is achieved through variation in the refractive index of the ring resonator produced by changing the injected carrier density through the application of bias voltage. Detail analysis of the switching characteristics reveals that the amount of switching depends on the refractive index change, which indeed is a strong function of injected carrier density and applied bias voltage. An isolation of 25 dB …

Recreational Use Of Acidic Pit Lakes—Human Health Considerations For Post Closure Planning, Andrea Hinwood, Jane Heyworth, Helen Tanner, C. D. Mccullough

Research outputs 2012

Pit lakes may form in mining voids that extend below groundwater level after mining ceases and many have been found to have elevated metals concentrations and low pH through acidic and metalliferous drainage (AMD). Pit lakes are often used for recreational activities including swimming, fishing and boating and poor water quality may present health risks to recreational users. Pit lakes also provide the opportunity for additional water resource uses. The Collie Coal Basin in south-western Australia currently has a number of pit lakes with moderate AMD effects which are also used for recreational pursuits. Twelve hundred questionnaires were mailed to …

Fussy Feeders: Phyllosoma Larvae Of The Western Rocklobster (Panulirus Cygnus) Demonstrate Prey Preference, M I Saunders, P A Thompson, A G Jeffs, Christin Sawstrom, N Sachlikidis, L E Beckley, A M Waite

Research outputs 2012

The Western Rocklobster (Panulirus cygnus) is the most valuable single species fishery in Australia and the largest single country spiny lobster fishery in the world. In recent years a well-known relationship between oceanographic conditions and lobster recruitment has become uncoupled, with significantly lower recruitment than expected, generating interest in the factors influencing survival and development of the planktonic larval stages. The nutritional requirements and wild prey of the planktotrophic larval stage (phyllosoma) of P. cygnus were previously unknown, hampering both management and aquaculture efforts for this species. Ship-board feeding trials of wild-caught mid-late stage P. cygnus phyllosoma in the eastern …

Sirtuin-1 Mediates The Obesity Induced Risk Of Common Degenerative Diseases: Alzheimer's Disease, Coronary Artery Disease And Type 2 Diabetes, Ian Martins, Andrea Wilson, Wei Ling Lim, Simon Laws, Stephanie Fuller, Ralph Martins

Research outputs 2012

Obesity, especially at mid-life, is a major risk factor for atherosclerosis, insulin resistance and the metabolic syndrome, which in turn contrib- ute to coronary artery disease (CAD), Type 2 diabetes and Alzheimer’s disease (AD). The rise in overweight and obesity in all societies is prompting intense research into the causes and effects of the condition. Obesity disrupts many body systems including glucose and lipid me- tabolism, circadian rhythms and liver function. It also causes or increases inflammation and oxi- dative stress. Within cells, the endoplasmic re- ticulum (ER) appears to be particularly suscep- tible to such metabolic disruption. Sirtuin 1 …

Visual Saliency Based On Fast Nonparametric Multidimensional Entropy Estimation, A. C. Ngo, G. Qiu, G. Underwood, Li-Minn Ang, K. P. Seng

Research outputs 2012

Bottom-up visual saliency can be computed through information theoretic models but existing methods face significant computational challenges. Whilst nonparametric methods suffer from the curse of dimensionality problem and are computationally expensive, parametric approaches have the difficulty of determining the shape parameters of the distribution models. This paper makes two contributions to information theoretic based visual saliency models. First, we formulate visual saliency as center surround conditional entropy which gives a direct and intuitive interpretation of the center surround mechanism under the information theoretic framework. Second, and more importantly, we introduce a fast nonparametric multidimensional entropy estimation solution to make information …

Performance Of Termite-Hill Routing Algorithm On Sink Mobility In Wireless Sensor Networks, Adamu M Zungeru, Li-Minn Ang, Kah Phooi Seng

Research outputs 2012

High efficient and energy-aware routing is an important issue for the design of resource constrained environments like Wireless Sensor Networks (WSNs). Many protocols have been developed for WSN that try to overcome the constraints that characterized this type of networks. Termite based routing protocols can add a significant contribution to assist in the maximization of the network lifetime without performance degradation. But this is only possible by means of an adaptable and balanced algorithm that takes into account the main constraints of WSN. This paper presents a biological inspired self-organized routing protocol for WSN which is based on termite colony …

Theism And Psychological Science: A Call For Rapprochement, Michael J. Vogel, Tyler A. Gerdin, Mark R. Mcminn

Faculty Publications - Doctor of Psychology (PsyD) Program

The authors offer two arguments for the inclusion of theism in natural science. First, an argument against excluding theism is offered. Though early roots of science promoted a view that it is a way to accumulate knowledge that is untainted by presuppositions and traditions, postmodern critiques call this into question. Scientists have sometimes rejected religion as a context-dependent, tradition-based way of knowing, yet science itself is also context-dependent and tradition-based. Second, an argument for including theism in psychological is offered. Theistic beliefs are relevant insofar as they are part of human experience for many, they represent a form of human …

Bad News For John Marshall, Gary S. Lawson, David Kopel

Faculty Scholarship

In "Bad News for Professor Koppelman: The Incidental Unconstitutionality of the Individual Mandate," we demonstrated that the individual mandate’s forced participation in commercial transactions cannot be justified under the Necessary and Proper Clause as the Clause was interpreted in McCulloch v. Maryland. Professor Andrew Koppelman’s response, "Bad News for Everybody," wrongly conflates that argument with a wide range of interpretative and substantive positions that are not logically entailed by taking seriously the requirement that laws enacted under the Necessary and Proper Clause must be incidental to an enumerated power. His response is thus largely unresponsive to our actual arguments.

Social Relationships And Mortality, Julianne Holt-Lunstad, Timothy B. Smith

Faculty Publications

Social relationships benefit not only mental health but also physical health. This review addresses the following questions: (1) What is the overall magnitude of the effect of social relationships on risk for premature death? (2) How generalized is the effect and are there factors known to influence this association? (3) What are the likely pathways by which social relationships influence longevity? The article concludes by discussing the implications of these findings for potential interventions aimed at reducing risk for mortality.

Using Radio-Telemetry To Assess The Risk European Starlings Pose In Pathogen Transmission Among Feedlots, Shannon M. Gaukler, H. Jeffrey Homan, George M. Linz, William J. Bleier

Human–Wildlife Interactions

We monitored site-use and movements of 102 radio-tagged European starlings (Sturnus vulgaris) during the winter months at 2 concentrated animal feeding operations (feedlots) in central Kansas. Our research investigated the spatial ecology of wintering starlings as part of a broad epidemiological study on the possible role of starlings in pathogen transmission at feedlots. Site fidelity was 0.677 and 0.552 (days at capture-site per total days tagged) for feedlots A and B, respectively. Minimal exchange (9%) occurred between feedlots A and B and was often followed by a roost-site change. Starlings rarely abandoned the feedlot where they were captured, …

The Effect Of European Starlings And Ambient Air Temperature On Salmonella Enterica Contamination Within Cattle Feed Bunks, James C. Carlson, Jeremy W. Ellis, Shelagh K. Tupper, Alan B. Franklin, George M. Linz

Human–Wildlife Interactions

European starlings (Sturnus vulgaris) are a known risk factor for the occurrence of microorganisms that are pathogenic to cattle and humans in concentrated animal feeding operations (CAFOs). Starling use of CAFOs is known to vary in response to weather; starling control operations on CAFOs often are timed to coincide with favorable environmental conditions to maximize take. The totality of this information suggests that disease risks in CAFOs associated with starlings may be influenced by environmental factors, such as temperature. In this study, we assessed the risk of Salmonella enterica contamination of cattle feed by modeling the interaction between …

Role Of Bird Movements In The Epidemiology Of West Nile And Avian Influenza Virus, Sabir B. Muzaffar, Nichola J. Hill, John Y. Takekawa, William M. Perry, Lacy M. Smith, Walter M. Boyce

Human–Wildlife Interactions

Avian influenza virus (AIV) is influenced by site fidelity and movements of bird hosts. We examined the movement ecology of American crows (Corvus brachyrhynchos) as potential hosts for West Nile virus (WNV) and greater white-fronted geese (Anser albifrons frontalis) as potential hosts for AIVs. Research was based on radio-telemetry studies conducted in the Central Valley of California, USA. While crows were restricted to a small area of only a few square kilometers, the distribution of the geese encompassed the northern Central Valley. The crows used 1.5 to 3.5 different roosting areas monthly from February through October, …

Brown Treesnakes: A Potential Invasive Species For The United States, Samantha Sue Kahl, Scott E. Henke, Marc A. Hall, David K. Britton

Human–Wildlife Interactions

Brown treesnakes (ˆ) are mildly venomous, exotic snakes that have the potential to become an invasive species in North America, Hawaii, and the Commonwealth of the Northern Mariana Islands. The snake is native to northern and eastern Australia, New Guinea, and other islands of northern and western Melanesia. The snakes were first found outside their native range on Guam in 1953. The exact date they reached the island is uncertain, but they are believed to have arrived on military cargo transport vessels some time during or just after World War II. During the years that followed, the population of brown …

Modification Of Net Configurations Of The Coda Netlauncher® To Enhance Bird Capture, Amanda M. Prisock, Brian S. Dorr, James C. Cumbee

Human–Wildlife Interactions

We modified and evaluated capture nets fired from the Coda Netlauncher® as a tool for capturing various avian species. We modified the netlauncher by using customized nets to maximize the area of the capture zone. We captured 137 birds, comprising 12 species, in 23 attempts between July 2008 and October 2009 using this method. Capture success rates varied from 25 to 69% were comparable to success rates reported for other capture methods for these species. However, individual capture success for different net configurations varied greatly from 3 to 65%. Minimal injuries and 2 bird fatalities were reported. The netlauncher, using …

A Model To Predict The Likelihood Of Cliff Swallow Nesting On Highway Structures In Northern California, Robert W. Coates, Michael Delwiche, W. Paul Gorenzel, Terrell P. Salmon

Human–Wildlife Interactions

Cliff swallows (Petrochelidon pyrrhonota) are colonially breeding migratory birds that frequently nest on highway structures. Under the Migratory Bird Treaty Act of 1918, people cannot harm swallows or their active nests. This restriction causes problems and delays for construction and maintenance divisions of many departments of transportation. In planning future projects, it would be useful for these divisions to have a habitat selection model that can predict the likelihood of cliff swallow nesting on a particular highway structure. We used logistic regression on data collected from 206 highway structures and 2 different land cover data sets to develop …

Sterilization As An Alternative Deer Control Technique: A Review, Jason R. Boulanger, Paul D. Curtis, Evan G. Cooch, Anthony J. Denicola

Human–Wildlife Interactions

Burgeoning white-tailed deer (Odocoileus virginianus) populations in suburban landscapes continue to impact communities and challenge natural resource managers. Increased deer-related damage to vegetation, ecosystems, and automobiles can exceed the tolerance of local stakeholders. We provide an overview of the potential efficacy of using surgical sterilization to help manage populations and conflicts associated with locally overabundant white-tailed deer populations. We review theoretical and fi eld studies pertaining to deer sterilization, and provide research priorities to help guide future sterilization efforts. Recent fi eld studies suggest that sterilization of female deer remains expensive, at approximately $1,000 per surgery. Sterilization may …

Examining A Potential Brown Treesnake Transport Pathway: Shipments From Guam, Samantha Sue Kahl, Scott E. Henke, Marc A. Hall, Andrea R. Litt, Gad Perry, David K. Britton

Human–Wildlife Interactions

Shipments of cargo and household goods have been identified as pathways for brown treesnake (Boiga irregularis) transport from Guam to other locations. We analyzed data regarding shipments of military household goods leaving Guam during 2006 to 2009 to identify the potential for human transport of brown treesnakes to the United States by determining when shipments most commonly occur and identifying primary receiving areas. We found that the number of shipments was highest during the months of May and June and that California receives more shipments (23% of total shipments) than any other location. Approximately 98% of shipments originated …

Efficacy, Effort, And Cost Comparisons Of Trapping And Acetaminophen-Baiting For Control Of Brown Treesnakes On Guam, Larry Clark, Peter J. Savarie, John A. Shivik, Stewart W. Breck, Brian S. Dorr

Human–Wildlife Interactions

Brown treesnakes (Boiga irregularis) are an invasive species to the island of Guam. Because they have extirpated the native forest avifauna on Guam and are a threat to other Pacific islands, the development of efficient and cost-effective methods to control them is desired. We compared the efficacy, cost, and effort required to remove brown treesnakes on 6-ha plots in forest scrub on Guam, using 2 methods: trapping and poison baiting. Toxic baits consisted of dead neonatal mice adulterated with 80-mg acetaminophen. To assess efficacy, we used mark-recapture methods to estimate snake abundance on plots 12 days before and 12 days …

Effects Of Grassland Alteration From Mowing And Fire On Bird Activity At A Colorado Airfield, Kara A. Carragher, Rick M. Clawges, Rick L. Bunn, Helen K. Pigage, Jon C. Pigage

Human–Wildlife Interactions

Grass management has been used for many years at airports in an attempt to reduce numbers of birds and other wildlife and the collisions with aircraft associated with them. We evaluated the impacts of grassland alteration by mowing and fi re on the abundance, diversity, and frequency of birds using 1 control and 2 experimental grass plots from 2009 to 2010 on a U.S. Army airfield in Colorado located in short-grass prairie. Density of breeding birds was highest in the mowed plot. Numbers of birds observed in 34 surveys conducted during the non-breeding season in the burned (x = 41) …

The Role, Size, And Effectiveness Of Safety Zones For Creating Refuges For White-Tailed Deer, Jacob L. Bowman

Human–Wildlife Interactions

White-tailed deer (Odocoileus virginianus) are overabundant in many areas, particularly in more developed landscapes where refuges may provide additional challenges for deer managers. Refuges have been widely used to sustain breeding stock in harvested populations and to mitigate other sources of mortality. As the landscape becomes more urbanized, local municipalities and states have implemented safety zones to reduce the probability of a hunter’s projectile from accidentally striking a building or its inhabitants. I evaluated if mandated safety zones in Delaware may constitute unintentional refuges. I used Delaware’s land-cover data to created buffers (i.e., 46, 91, and 183 m) …

Top Tens In 2012: Patent, Trademark, Copyright And Trade Secret Cases, Stephen M. Mcjohn

Suffolk University Law School Faculty Works

back on the scope of patent subject matter in Prometheus, while according Congress great latitude in extending copyright protection in Golan. Prometheus was one of a number of cases in which the concept of functionality cut across the various areas of intellectual property. Prometheus cut back on patents on innovations that were not sufficiently functional, because they effectively claimed a law of nature. The Federal Circuit, in Myriad Genetics, by contrast, held isolated genes patentable (and the Supreme Court has decided to hear that case). The strongest rationale may be that isolated genes play different functions than their counterpart in …

Grandparental Death: Through The Lens Of An Asian Child, Wing-Fu Lai

The Qualitative Report

Bereavement has been extensively studied over the years, yet scholarly work depicting, with the first-person perspective, the experience of childhood bereavement is severely lacking. The research question I set out to answer here is: What is it like as an Asian child to experience bereavement following grandparental death? As such, self-introspection was exercised, and this, together with the diaries and free writings generated at the time of my grandma’s death, was used as the basis for autoethnographic reflections. It is hoped that my story presented here can offer a psychological portrayal of an Asian child enduring grandparental death, and illuminate …

Think It, Draft It, Post It: Creating Legal Poster Presentations, Samantha A. Moppett

Suffolk University Law School Faculty Works

While oral presentations are the traditional mode of conveying one’s ideas at legal conferences, there is another approach that is underutilized – poster presentations. Essentially, a poster presentation is a visual display of a presenter’s idea along with an opportunity for one-on-one interaction between the presenter and the audience. Poster presentations – a relatively new form of presentation at legal conferences – provide an excellent medium for presenting research or innovative teaching ideas in an informal manner.

Given the dearth of scholarship on the topic of legal poster presentations, this article advances the discussion. Specifically, the article provides some background …
