Cargo Bikes As A Growth Area For Bicycle Vs. Auto Trips: Exploring The Potential For Mode Substitution Behavior, William W. Riggs

William W. Riggs

Cargo bikes are increasing in availability in the United States. While a large body of research has continued to investigate traditional bike transportation, cargo bikes offer the potential to capture trips for those that might otherwise be made by car. To investigate this, data from a survey of cargo bike users are evaluated using descriptive and inferential statistics. The survey queried how use and travel dynamics of characteristics with the hypothesis that cargo bike ownership has the potential to contribute to mode substitution behavior. From a descriptive standpoint, 68.9% of those surveyed changed their travel behavior after purchasing a cargo …

Evaluation Of The Impact Of Biofield Treatment On Physical And Thermal Properties Of Casein Enzyme Hydrolysate And Casein Yeas T Peptone, Mahendra Kumar Trivedi

Mahendra Kumar Trivedi

In the present study, the influence of biofield treatment on physical and thermal properties of Casein Enzyme Hydrolysate (CEH) and Casein Yeast Peptone (CYP) were investigated. The control and treated samples were characterized by Fourier transform infrared (FT-IR) spectroscopy, differential scanning calorimetry (DSC), Thermo Gravimetric Analysis (TGA), particle size and surface area analysis. The FTIR results revealed that biofield treatment has caused reduction of amide group (amide-I and amide-II) stretching vibration peak that is associated with strong intermolecular hydrogen bonding in treated CEH as compared to control. However, no significant changes were observed in FTIR spectrum of treated CYP. The …

Government Insurance, Information, And Asset Prices, Danilo Lopomo Beteto Wegner

Danilo Lopomo Beteto Wegner

An investment decision problem is studied, in a framework where the government offers insurance against the possibility of the price of a risky asset falling drastically. The problem is considered under different informational scenarios, i.e., information quality, under which agents have to infer the state of fundamentals of the economy. Changes in information quality is shown to affect equilibrium prices despite no concomitant changes in the fundamentals, creating excess volatility. The possibility of government intervention is shown to increase equilibrium prices, which can be ordered as a function of information quality. Empirical evidence supporting the model is presented.

Keri Schwab

Towards a model of optimal family leisure Keri A. Schwaba and Daniel L. Dustin Recreation, Parks, & Tourism Administration Department, California Polytechnic State University, San Luis Obispo, CA, USA; bDepartment of Parks, Recreation, and Tourism, University of Utah, Salt Lake City, UT, USA Leisure is an important component of family life, yet many families struggle to focus on or participate in family leisure. This study examined the structural characteristics of family life that can impede or promote family leisure. Employing a systems perspective, a literature-based model of family leisure was created, and in-depth interview data were gathered from three families …

Are Citizens “Receiving The Treatment”? Assessing A Key Link In Contextual Theories Of Public Opinion And Political Behavior, Benjamin J. Newman, Yamil R. Valez, Todd K. Hartman, Alexa Bankert

Todd K. Hartman

The theorization and empirical exploration of contextual effects is a long standing feature of public opinion and political behavior research. At present, however, there is little to no evidence that citizens actually perceive the local contextual factors theorized to influence their attitudes and behaviors. In this article, we focus on two of the most prevalent contextual factors appearing in theories—racial/ethnic and economic context—to investigate whether citizens’ perceptions of their local ethnic and economic contexts map onto variation in the actual ethnic composition and economic health of these environments. Using national survey data combined with Census data, and focusing on the …

Health Disclaimers And Website Credibility Markers: Guidance For Consumer Health Reference In The Affordable Care Act Era, Deborah H. Charbonneau

Deborah H. Charbonneau

This article reports on the current state of health disclaimers, online health resources, and credibility markers provided on public library websites (N = 105) for those seeking health information. In light of the Affordable Care Act (ACA), these findings have implications for consumer health reference services in public libraries. Approximately half of the public library websites in the study sample (n = 52, 49.5%) referred users to the ACA Health Insurance Marketplace website (HealthCare.gov). When referring to online consumer health resources, a small number of public library websites identified the authors of online health content (n = 16, 15.2%) or …

Inclusively Walkable: Exploring The Equity Of Walkable Housing In The San Francisco Bay Area, William W. Riggs

William W. Riggs

This study evaluates the inclusiveness of walkable housing in the San Francisco Bay Area. Using a series of regression models that control for an array of factors, this study finds that blacks are more likely to live in less walkable areas, a factor which could result in increased societal costs. These models suggest that this factor may mask other highly collinear factors including income, education, and social networks. This phenomenon is explored with qualitative interviews that reinforce this finding and illustrate the many push and pull factors that influence housing choice. These findings are then used to develop potential hypotheses …

Animal Models And Therapeutic Molecular Targets Of Cancer: Utility And Limitations., Maria Cekanova Ms, Rndr, Phd, Kusum Rathore

Maria Cekanova MS, RNDr, PhD

Cancer is the term used to describe over 100 diseases that share several common hallmarks. Despite prevention, early detection, and novel therapies, cancer is still the second leading cause of death in the USA. Successful bench-to-bedside translation of basic scientific findings about cancer into therapeutic interventions for patients depends on the selection of appropriate animal experimental models. Cancer research uses animal and human cancer cell lines in vitro to study biochemical pathways in these cancer cells. In this review, we summarize the important animal models of cancer with focus on their advantages and limitations. Mouse cancer models are well known, …

The Strauss Conjecture On Kerr Black Hole Backgrounds, Hans Lindblad, Jason Metcalfe, Christopher D. Sogge, Mihai H. Tohaneanu, Chengo Wang

Mihai H. Tohaneanu

We examine solutions to semilinear wave equations on black hole backgrounds and give a proof of an analog of the Strauss conjecture on the Schwarzschild and Kerr, with small angular momentum, black hole backgrounds. The key estimates are a class of weighted Strichartz estimates, which are used near infinity where the metrics can be viewed as small perturbations of the Minkowski metric, and a localized energy estimate on the black hole background, which handles the behavior in the remaining compact set.

Mycobacterium Ulcerans Fails To Infect Through Skin Abrasions In A Guinea Pig Infection Model: Implications For Transmission, H R. Williamson, L Mosi, Robert L. Donnell, M Aqqad, R W. Merritt, P L. Small

Robert L Donnell DVM, Ph.D., DACVP College of Veterinary Medicine

Transmission of M. ulcerans, the etiological agent of Buruli ulcer, from the environment to humans remains an enigma despite decades of research. Major transmission hypotheses propose 1) that M. ulcerans is acquired through an insect bite or 2) that bacteria enter an existing wound through exposure to a contaminated environment. In studies reported here, a guinea pig infection model was developed to determine whether Buruli ulcer could be produced through passive inoculation of M. ulcerans onto a superficial abrasion. The choice of an abrasion model was based on the fact that most bacterial pathogens infecting the skin are able to …

Magnetic Resonance Imaging (Mri) Spinal Cord And Canal Measurements In Normal Dogs, Silke Hecht, M M. Huerta, Robert B. Reed

Silke Hecht

The goal of this study was to establish Magnetic resonance imaging (MRI) reference ranges for spinal measurements in normal dogs. Forty dogs (1–10 kg, 11–20 kg, 21–30 kg, > 30 kg; 10 dogs per category) underwent spinal MRI. Measurements were performed on sagittal T2-W images at the level of the 4th thoracic vertebra (T4), the 9th thoracic vertebra (T9) and the 3rd lumbar vertebra (L3). Spinal canal diameter (mm) ranged from 6.07 ± 0.63 (1–10 kg) to 8.27 ± 1.15 (> 30 kg) at the level of T4; 6.55 ± 0.61 (1–10 kg) to 9.04 ± 1.26 (> 30 kg) at …

Decoding Prejudice Toward Hispanics: Group Cues And Public Reactions To Threatening Immigrant Behavior, Todd K. Hartman, Benjamin J. Newman, C. Scott Bell

Todd K. Hartman

Consistent with theories of modern racism, we argue that white, non-Hispanic Americans have adopted a “coded,” race-neutral means of expressing prejudice toward Hispanic immigrants by citing specific behaviors that are deemed inappropriate—either because they are illegal or threatening in an economic or cultural manner. We present data from a series of nationally representative, survey-embedded experiments to tease out the distinct role that anti-Hispanic prejudice plays in shaping public opinion on immigration. Our results show that white Americans take significantly greater offense to transgressions such as being in the country illegally, “working under the table,” and rejecting symbols of American identity, …

Social Dominance And The Cultural Politics Of Immigration, Benjamin J. Newman, Todd K. Hartman, Charles S. Taber

Todd K. Hartman

We argue that conflict over immigration largely concerns who bears the burden of cultural transaction costs, which we define as the costs associated with overcoming cultural barriers (e.g., language) to social exchange. Our framework suggests that the ability of native-born citizens to push cultural transaction costs onto immigrant outgroups serves as an important expression of social dominance. In two novel studies, we demonstrate that social dominance motives condition emotional responses to encountering cultural transaction costs, shape engagement in cultural accommodation behavior toward immigrants, and affect immigration attitudes and policy preferences.

From The Outside Looking In: A Response To The Hijacking Of Recreational Therapy, Daniel L. Dustin, Kelly S. Bricker, Keri A. Schwab

Keri Schwab

Where does Dr. Austin want his line of thought to lead and what does he expect from the larger field of parks and recreation in return? Is he after reassurance that recreational therapy is valued by the rest of us? Does he want recreation therapists to be acknowledged as the closest thing we have in our midst to medical doctors? Or does he want recreational therapy to disassociate itself from the field of parks and recreation altogether? If recreation therapists want to be viewed as distinct and different from the rest of us, if it is autonomy they are after, …

Establishing Mission Requirements Based On Consideration Of Aircraft Operations, Robert A. Mcdonald

Robert A. McDonald

The design requirements for a next-generation commercial aircraft can do much to secure its fate as a success or failure. New aircraft are often designed to meet or surpass the capabilities of an existing aircraft they are intended to replace. However, in the case of unconventional aircraft, this could lead to significant overdesign resulting in nonviable concepts. Instead, a method of analyzing observed aircraft use is presented with the intent of establishing a set of requirements based on replacing aircraft utility instead of capability. Two aircraft in the commercial fleet are used as example cases, and launch customers for each …

Education, Complaints, And Accountability, Juan Botero, Alejandro Ponce, Andrei Shleifer

Alejandro Ponce

Better educated countries have better governments, an empirical regularity that holds in both dictatorships and democracies. A possible reason for this fact is that educated people are more likely to complain about misconduct by government officials and that more frequent complaints encourage better behavior from officials. Newly assembled individual-level survey data from the World Justice Project show that, within countries, better educated people are more likely to report official misconduct. The results are confirmed using other survey data on reporting crime and corruption. Citizen complaints might thus be an operative mechanism that explains the link between education and the quality …

Solar Energy Collection Analysis Tool For Conceptual Aircraft Design, Grant M. Glazebrook, Robert A. Mcdonald

Robert A. McDonald

As battery energy storage and solar cell technology improve, solar aircraft are increasingly being considered for high altitude long endurance missions. Although solar vehicles may theoretically remain on station indefinitely using the sun as a power source, their design and feasibility is sensitive to mission planning details as specific as the time history of the vehicle’s deck orientation relative to the sun; the energy available for capture by the on-board solar array is governed by the solar incidence angle, and at certain orientations, the vehicle may cast shadows on itself and further reduce its energy capture capabilities. To quantify these …

Electric Motor Modeling For Conceptual Aircraft Design, Robert A. Mcdonald

Robert A. McDonald

Electric motors have achieved very high efficiency and reliability; and in some cases, very high specific power. As the energy storage capabilities of batteries and fuel cells advance, these technologies are increasingly being considered for aircraft primary propulsion. In order to design electric aircraft, aircraft designers must be able to understand and model the performance characteristics of electric motors. Most electric machine modeling techniques either ignore potentially important phenomena or require an extreme level of detail undesirable for conceptual aircraft design. In this paper, a compromise approach is proposed which can capture the salient details of motor performance without requiring …

Enabling Rapid Conceptual Design Using Geometry-Based Multi-Fidelity Models In Vsp, Joel B. Belben, Robert A. Mcdonald

Robert A. McDonald

Four types of reduced fidelity or degenerate geometric representations have been defined and implemented in VSP for the purpose bridging the gap between conceptual design and analysis. They are Degenerate Surface, Degenerate Plate, Degenerate Stick, and Degenerate Point, corresponding to three-, two-, one-, and zero-dimensional representations of underlying geometry, respectively. The information contained in these representations was targeted specifically at lifting line theory, vortex lattice, equivalent beam, and equivalent plate methods, but could be used for other analysis techniques. The ability to output this information in both csv and Matlab file formats has been implemented in VSP. Ongoing work seeks …

High­- Accuracy Quartic Force Field Calculations For The Spectroscopic Constants And Vibrational Frequencies Of 11A′ L-­C3H-­: A Possible Link To Lines Observed In The Horsehead Nebula Pdr, Ryan C. Fortenberry, Xinchuan Huang, T. D. Crawford, Timothy J. Lee

Ryan C. Fortenberry

It has been shown that rotational lines observed in the Horsehead nebula photodissociation region (PDR) are probably not caused by l-C₃H⁺, as was originally suggested. In the search for viable alternative candidate carriers, quartic force fields are employed here to provide highly accurate rotational constants, as well as fundamental vibrational frequencies, for another candidate carrier: 1¹ A' C₃H^–. The ab initio computed spectroscopic constants provided in this work are, compared to those necessary to define the observed lines, as accurate as the computed spectroscopic constants for many of the known interstellar …

Spectroscopic Constants And Vibrational Frequencies For L­-C3H+ And Isotopologues From Highly­Accurate Quartic Force Fields: The Detection Of L­-C3H+ In The Horsehead Nebula Pdr Questione, Xinchuan Huang, Ryan C. Fortenberry, Timothy J. Lee

Ryan C. Fortenberry

Very recently, molecular rotational transitions observed in the photon-dominated region of the Horsehead nebula have been attributed to l-C₃H⁺. In an effort to corroborate this finding, we employed state-of-the-art and proven high-accuracy quantum chemical techniques to compute spectroscopic constants for this cation and its isotopologues. Even though the B rotational constant from the fit of the observed spectrum and our computations agree to within 20 MHz, a typical level of accuracy, the D rotational constant differs by more than 40%, while the H rotational constant differs by three orders of magnitude. With the likely errors in …

Socially-Mediated Internet Surveys (Smis): Recruiting Participants For Online Experiments, Erin C. Cassese, Leonie Huddy, Todd K. Hartman, Lilliana Mason, Christopher R. Weber

Todd K. Hartman

Socially-Mediated Internet Surveys (SMIS) is a new method to obtain web-based, adult samples for experimental political science research. SMIS targets central figures in online social networks to help recruit participants, who visit their websites. We present data from six samples collected using the SMIS method and compare them to those gathered by other sampling approaches such as Amazon’s Mechanical Turk. While not representative of the general adult population, our SMIS samples are significantly more diverse than undergraduate convenience samples, not just demographically but also politically. Moreover, we also discuss how the SMIS approach can be used to target special subpopulations …
