Quantum Mechanics And Ethical Antirealism: A Counter-Analogy To Boyd, Justin Lawson

Philosophy

In his paper How to Be a Moral Realist Boyd attempts to show how cases of ethical indeterminacy can be accounted for from an ethical realist’s standpoint. Boyd describes cases of extensional vagueness in the life-sciences which arise from knowable and definite underlying structures and draws an analogy to ethics to argue his case. This paper argues that an equally compelling analogy can be drawn between another type of scientific indeterminacy – that in quantum mechanics – and the related ethical cases. Because quantum mechanical uncertainty (on the Copenhagen interpretation) is a real and not merely epistemic limitation on physical …

Design And Development Of An Integrated Waste Management System For Huai Nam Khun, Thailand, Annie Duong

Industrial and Manufacturing Engineering

Background

A rural village in Thailand has always been limited in access to waste collection services and processing facilities. As a result, their behaviors of disposing waste in ineffective manners such as dumping and burning causes a variety of environmental impacts. In addition, the people dwelling in these areas are often unaware of the health risks associated to these types of engagements because of the inadequate education system. For a long time coming these circumstances remained untouched until a non-profit organization recently shed light to the need for a solution. An investigation, to develop a design solution in order to …

Expanding Opportunity Structures: Parental Investments In Education, Migration, And Extrinsic Risk Reduction Among Indo-Fijians, Dawn B. Neill

Social Sciences

Parental investment strategies are contingent on parental capacities and ecology. Parental embodied capital may be important in aspiration construction and investments in children’s human capital, which is especially important in urban environments where skills are directly tied to wage income. For Indo-Fijians, rural ecology strongly limits opportunities. Here this limitation is conceptualized as extrinsic risk and immune to reduction through enhanced parental investment. Urban migration is interpreted as a risk reduction strategy, given an expanded urban opportunity structure (lower extrinsic risk). Qualitative and quantitative data from 678 Indo-Fijian children suggest that, contingent on parental capacities, parents migrate in response to …

Small Heat Shock Protein Responses Differ Between Chaparral Shrubs From Contrasting Microclimates, Charles A. Knight

Biological Sciences

Small heat shock protein (sHsp) responses were studied for two evergreen perennial shrubs in the northern California chaparral; one common on warm, south-facing slopes (Ceanothus cuneatus), and the other on cooler, north-facing slopes (Prunus ilicifolia). Small Hsp expression was induced experimentally for field collected leaves. Leaf collections were made where the species co-occur. Small Hsp expression was quantified using two antibodies, one specific to a chloroplast 22 kD sHsp and another that detects a broad range of sHsps. Differences between chloroplast sHsp accumulation, which protects thermally labile proteins in PSII, and the general sHsp response were …

On The Relationship Between Pollen Size And Genome Size, Charles A. Knight, Rachel B. Clancy, Lars Götzenberger, Leighton Dann, Jeremy M. Beaulieu

Biological Sciences

Here we test whether genome size is a predictor of pollen size. If it were, inferences of ancient genome size would be possible using the abundant paleo-palynolgical record. We performed regression analyses across 464 species of pollen width and genome size. We found a significant positive trend. However, regression analysis using phylogentically independent contrasts did not support the correlated evolution of these traits. Instead, a large split between angiosperms and gymnosperms for both pollen width and genome size was revealed. Sister taxa were not more likely to show a positive contrast when compared to deeper nodes. However, significantly more congeneric …

Web-Based Student Data Collection And Assessment, Thomas J. Bensky

Physics

Gathering information from students for learning assessment is a critical need of any teacher. In this paper, the tech-savvy instructor is introduced to basic techniques of creating custom, web-based, student-data collection software. Despite widespread deployment of generalized course management systems, the author argues that small, ultra-customized data collection methodologies, can be of great help in collecting and assessing student input, reducing demands on paper, and easing the familiar grading bottleneck while satisfying an individual's pedagogical needs.

Challenging Computer Software Frontiers And The Human Resistance To Change, Jens Pohl

Architecture

This paper examines the driving and opposing forces that are governing the current paradigm shift from a data-processing information technology environment without software intelligence to an information-centric environment in which data changes are automatically interpreted withinthe context of the application domain. The driving forces are related to the large quantity of dataand the complexity of networked systems that both call for software intelligence. The opposing forces are non-technical and due to the natural human resistance to change.

Based on this background the paper describes current information-centric technology, proposes avision of intelligent software system capabilities, and identifies four areas of necessary …

Also included is an educational model based on the project and recommendations for the use of narrative …

Effects Of Yogurt Starter Cultures On The Survival Of Lactobacillus Acidophilus, Elizabeth W. Ng, Marie Yeung, Phillip S. Tong

Biological Sciences

Recognized to confer health benefits to consumers, probiotics such as Lactobacillus acidophilus are commonly incorporated into fermented dairy products worldwide; among which yogurt is a popular delivery vehicle. To materialize most of the putative health benefits associated with probiotics, an adequate amount of viable cells must be delivered at the time of consumption. However, the loss in their viabilities during refrigerated storage has been demonstrated previously. This study focused on the effects of yogurt starter cultures on the survival of five strains of L. acidophilus, with emphases on low pH and acid production. Differential survival behavior between L. acidophilus strains …

Programmable Diagnostic Devices Made From Paper And Tape, Andres W. Martinez, Scott T. Phillips, Zhihong Nie, Chao-Min Cheng, Emanuel Carrilho, Benjamin J. Wiley, George M. Whitesides

Chemistry and Biochemistry

This paper describes three-dimensional microfluidic paper-based analytical devices (3-D μPADs) that can be programmed (postfabrication) by the user to generate multiple patterns of flow through them. These devices are programmed by pressing single-use ‘on’ buttons, using a stylus or a ballpoint pen. Pressing a button closes a small space (gap) between two vertically aligned microfluidic channels, and allows fluids to wick from one channel to the other. These devices are simple to fabricate, and are made entirely out of paper and double-sided adhesive tape. Programmable devices expand the capabilities of μPADs and provide a simple method for controlling the movement …

Millimeter-Scale Contact Printing Of Aqueous Solutions Using A Stamp Made Out Of Paper And Tape, Chao-Min Cheng, Aaron D. Mazzeo, Jinlong Gong, Andres W. Martinez, Scott T. Phillips, Nina Jain, George M. Whitesides

Chemistry and Biochemistry

This communication describes a simple method for printing aqueous solutions with millimeter-scale patterns on a variety of substrates using an easily fabricated, paper-based microfluidic device (a paper-based ―stamp‖) as a contact printing device. The device is made from inexpensive materials, and it is easily assembled by hand; this method is thus accessible to a wide range of laboratories and budgets. A single device was used to print over 2500 spots in less than three minutes at a density of 16 spots per square centimetre. This method provides a new tool to pattern biochemicals—reagents, antigens, proteins, and DNA—on planar substrates. The …

The Systemic Correlation Between Mental Models And Sustainable Design: Implications For Engineering Educators, Linda Vanasupa, Roger Burton, Jonathan Stolk, Julie B. Zimmerman, Larry J. Leifer, Paul T. Anastas

Materials Engineering

Many studies have illuminated our understanding of the kinds of competencies and behaviors exhibited by effective designers. Against the backdrop of global challenges made more urgent by unintentional negative impacts of engineered products and systems, however, we are left to deduce that our ways of educating engineering designers is fundamentally flawed. We assert that one can trace the cause of our collective, unintended negative consequences to the mental models of reality that we consciously or unconsciously carry. In this paper, we present the case for developing awareness and facility with mental models. We also suggest an alternate mental model as …

Using On‐Line Data Sources To Allow Students To Test Hypotheses About River Flow And Effects On Remotely Sensed Coastal Ocean Properties., Lawrence B. Cohoon, Kristin M. Hardy, Dustin M. Allen

Biological Sciences

This exercise shows students how to relate remotely sensible properties of coastal waters to variations in river discharge using on‐line data resources. Students can then test hypotheses about the effects of climate changes (drought and wet periods), anthropogenic impacts (urbanized, agricultural, or undeveloped watersheds), or seasonality on river discharges and their consequences, if any, on coastal water quality as determined from remotely sensed properties. River flow has been measured for various periods of time, in some cases from almost the beginning of the 20^th century, at many locations throughout the U.S. by the U.S. Geological Survey, with data on …

Optical To Electrical Converter, Dietrich Reimer

Electrical Engineering

In this project I will be receiving two optical inputs from a tunable laser. As well as a Data valid signal that will indicate if my circuit should read inputs when valid or if the signal is not valid my circuit should hold until a valid signal is reapplied to avoid false zero crossings. The output of my circuit should be a digital signal that has a rising or falling edge when the two optical inputs have a zero crossing. This output will be a clock trigger that will input into the optical receiver of the overall optical coherence tomography …

Design, Fabrication, And Evaluation Of An All-Grain Brewing System, Alex Jensen

BioResource and Agricultural Engineering

A propane burner system was design for to use with an existing all grain brewing system. The use of a pump was used to create a recalculating mash system. The evaluation of the entire system included determining the amount of potential sugars which could be extracted from the malted grains and comparing them to the actual amount of sugar extracted prior to fermentation. An expected value was achieved. Another analysis looks at how efficient the system was at turning the total water used into a drinkable final product.

Bioluminescence In The Sea, Steven H.D. Haddock, Mark A. Moline, James F. Case

Biological Sciences

Bioluminescence spans all oceanic dimensions and has evolved many times—from bacteria to fish—to powerfully influence behavioral and ecosystem dynamics. New methods and technology have brought great advances in understanding of the molecular basis of bioluminescence, its physiological control, and its significance in marine communities. Novel tools derived from understanding the chemistry of natural light-producing molecules have led to countless valuable applications, culminating recently in a related Nobel Prize. Marine organisms utilize bioluminescence for vital functions ranging from defense to reproduction. To understand these interactions and the distributions of luminous organisms, new instruments and platforms allow observations on individual to oceanographic …

The Metabolic Demands Of Swimming Behavior Influence The Evolution Of Skeletal Muscle Fiber Design In The Brachyuran Crab Family Portunidae, Kristin M. Hardy, Sean C. Lema, Stephen T. Kinsey

Biological Sciences

We investigated the influence of intracellular diffusion on muscle fiber design in several swimming and non-swimming brachyuran crabs. Species with sustained swimming behavior had aerobic dark fibers subdivided into small metabolic functional units, creating short diffusion distances necessary to support the high rates of aerobic ATP turnover associated with endurance activity. This dark fiber design was observed in all swimming species including Ovalipes ocellatus, which has apparently evolved swimming behavior independently of other Portunidae. In addition, we observed fiber and subdivision size-dependent differences in organelle distribution. Mitochondria, which rely on oxygen to function, were uniformly distributed in small fibers/subdivisions, …

Morphological Assessment Of Basic Multicellular Unit Resorption Parameters In Dogs Shows Additional Mechanisms Of Bisphosphonate Effects On Bone, Matthew R. Allen, Antonia M. Erickson, Xiang Wang, David B. Burr, R. Bruce Martin, Scott J. Hazelwood

Biomedical Engineering

Bisphosphonates (BPs) slow bone loss by reducing initiation of new basic multicellular units (BMUs). Whether or not BPs simply prevent osteoclasts from initiating new BMUs that resorb bone or also reduce the amount of bone they resorb at the BMU level is not clear. The goal of this study was to determine the effects of BPs on three morphological parameters of individual BMUs, resorption depth (Rs.De), area (Rs.Ar), and width (Rs.Wi). After 1 year of treatment with vehicle (VEH), alendronate (ALN; 0.10, 0.20, or 1.00 mg/kg/day), or risedronate (RIS; 0.05, 0.10, or 0.50 mg/kg/day), resorption cavity morphology was assessed in …

Dual Polarization Interferometry For Small Molecules Drug Development, Sarwia Nawim, Brett Chromy, Lindsey Evans

STAR Program Research Presentations

Tularemia, also known as rabbit fever, is an infectious disease caused by the gram-negative bacterium Francisella tularensis. Transmission to animals and humans occurs via several routes, including ingestion of contaminated water, or inhalation of contaminated dusts or aerosols, tick bites, and skin contact with infected animals. Because of its highly pathogenic and opportunistic nature, F. tularensis is a likely candidate for use as an airborne biological weapon. For this reason, developing a vaccine and identifying appropriate treatments are critical to effective bioterrorism preparedness and response. It may exist in nature within encysted amoeba, which may represent a similar survival strategy …
