    The Political Economy: Political Attitudes and Economic Behavior

    Get PDF
    It has long been recognized that voters bring their political behaviors in line with economic assessments. Recent work, however, suggests that citizens also engage in economic behaviors that align with their confidence—or lack thereof—in the political system. This alignment can happen consciously or, as we suggest, unconsciously, in the same way that positivity carries over to other behaviors on a micro-level. Using monthly time series data from 1978 to 2008, we contribute further evidence of this relationship by demonstrating that political confidence affects consumer behavior at the aggregate level over time. Our analyses employ measures more closely tied to the theoretical concepts of interest while simultaneously accounting for the complex relationships between subjective and objective economic indicators, economic behavior, political attitudes, and the media. Our results suggest that approval of the president not only increases the electorate’s willingness to spend money, but also affects the volatility of this spending. These findings suggest that the economy is influenced by politics beyond elections, and gives the “Chief Economist” another avenue by which they can affect the behavior of the electorate

    Current Mobile Payment Procedures on the German Market from the View of Customer Requirements

    Get PDF
    The key to mobile payment acceptance is in the hands of customers. In this paper we use the results of the mobile payment survey MP1 in order to identify and roughly weigh the most relevant acceptance criteria. The outcome of the paper is an evaluation scheme containing the covered payment scenarios, important main criteria (security, costs and convenience) and additional functionality requirements for each MP procedure. The scheme is based on empirical results and can assess a given MP procedure with regard to customer acceptance as well as to compare different procedures. The operational MP procedures Paybox, I-mode and Vodafone m-pay are examined and compared according to the scheme. Finally, a prospect is given to possible further development of mobile payment procedures in the direction of an integrative universal mobile payment system (UMPS).

    INEL Spray-forming Research

    Get PDF
    Spray forming is a near-net-shape fabrication technology in which a spray of finely atomized liquid droplets is deposited onto a suitably shaped substrate or mold to produce a coherent solid. The technology offers unique opportunities for simplifying materials processing without sacrificing, and oftentimes substantially improving, product quality. Spray forming can be performed with a wide range of metals and nonmetals, and offers property improvements resulting from rapid solidification (e.g., refined microstructures, extended solid solubilities and reduced segregation). Economic benefits result from process simplification and the elimination of unit operations. Researchers at the Idaho National Engineering Laboratory (INEL) are developing spray-forming technology for producing near-net-shape solids and coatings of a variety of metals, polymers, and composite materials. Results from several spray forming programs are presented to illustrate the range of capabilities of the technique as well as the accompanying technical and economic benefits. Low-carbon steel strip greater than 0.75 mm thick and polymer membranes for gas/gas and liquid/liquid separations that were spray formed are discussed; recent advances in spray forming molds, dies, and other tooling using low-melting-point metals are described

    Local Monopsony Power in the Market for Broilers - Evidence from a Farm Survey

    Get PDF
    The exercise of monopsony power by broiler processing firms is plausible because production occurs within localized complexes, which limits the number of integrators with whom growers can contract. In addition, growers face distinct hold-up risks as broiler production requires a substantial investment in specific assets and most production contracts do not involve long-term purchasing commitments by integrators. This paper provides an initial exploration of the links between the local concentration of broiler integrators and grower compensation under production contracts using data from the 2006 broiler version of USDA’s Agricultural Resource Management Survey. Results of this preliminary study, which accounts for characteristics of the operation and specific features of the production contract, suggest a small but economically meaningful effect of concentration on grower concentration. Limitations of the current analysis and future possible model extensions are discussed.poultry, broilers, market power, monopsony, production contracts, Livestock Production/Industries, Marketing,

    An Exploratory Investigation of a Flipped Classroom Model in Human Services Education

    Get PDF
    Human services education has unique needs due to the practical elements that are a part of preparing students for the field. One aspect is for students to graduate with a firm capacity to enact the skill detailed by the National Organization of Human Services (NOHS, n.d.). A blending of on-campus and on-line components has been found to encourage higher order thinking and offer experiential learning (Rehfuss, Kirk-Jenkins, & Milliken, 2015). The flipped classroom pedagogical model offers one potential way for educators to create an environment that facilitates the learning needed and recommended. This study altered a class to the flipped classroom model, and then used two type of data collection, a survey given twice during a semester and reflections written as a part of the class’ expectation. This was done to explore human services undergraduates’ reactions to the pedagogical model. Implications and lines of further enquiry are included

    Time to publication for NIHR HTA programme-funded research: a cohort study

    Get PDF
    ObjectiveTo assess the time to publication of primary research and evidence syntheses funded by the National Institute for Health Research (NIHR) Health Technology Assessment (HTA) Programme published as a monograph in Health Technology Assessment and as a journal article in the wider biomedical literature.Study designRetrospective cohort study.SettingPrimary research and evidence synthesis projects funded by the HTA Programme were included in the cohort if they were registered in the NIHR research programmes database and was planned to submit the draft final report for publication in Health Technology Assessment on or before 9 December 2011.Main outcome measuresThe median time to publication and publication at 30?months in Health Technology Assessment and in an external journal were determined by searching the NIHR research programmes database and HTA Programme website.ResultsOf 458 included projects, 184 (40.2%) were primary research projects and 274 (59.8%) were evidence syntheses. A total of 155 primary research projects had a completion date; the median time to publication was 23?months (26.5 and 35.5?months to publish a monograph and to publish in an external journal, respectively) and 69% were published within 30?months. The median time to publication of HTA-funded trials (n=126) was 24?months and 67.5% were published within 30?months. Among the evidence syntheses with a protocol online date (n=223), the median time to publication was 25.5?months (28?months to publication as a monograph), but only 44.4% of evidence synthesis projects were published in an external journal. 65% of evidence synthesis studies had been published within 30.0?months.ConclusionsResearch funded by the HTA Programme publishes promptly. The importance of Health Technology Assessment was highlighted as the median time to publication was 9?months shorter for a monograph than an external journal article

    Manual Loading Distribution During Carrying Behaviors: Implications for the Evolution of the Hominin Hand

    Get PDF
    The human hand is unparalleled amongst primates in its ability to manipulate objects forcefully and dexterously. Previous research has predominantly sought to explain the evolution of these capabilities through an adaptive relationship between more modern human-like anatomical features in the upper limb and increased stone tool production and use proficiency. To date, however, we know little about the influence that other manipulatively demanding behaviors may have had upon the evolution of the human hand. The present study addresses one aspect of this deficiency by examining the recruitment of the distal phalanges during a range of manual transportation (i.e. carrying) events related to hominin behavioral repertoires during the Plio-Pleistocene. Specifically, forces on the volar pad of each digit are recorded during the transportation of stones and wooden branches that vary in weight and size. Results indicate that in most instances, the index and middle fingers are recruited to a significantly greater extent than the other three digits during carrying events. Relative force differences between digits were, however, dependent upon the size and weight of the object transported. Carrying behaviors therefore appear unlikely to have contributed to the evolution of the robust thumb anatomy observed in the human hand. Rather, results suggest that the manual transportation of objects may plausibly have influenced the evolution of the human gripping capabilities and the 3rd metacarpal styloid process

    Photoreductive dissolution of ferrihydrite by methanesulfinic acid: Evidence of a direct link between dimethylsulfide and iron-bioavailability

    Get PDF
    Within open‐ocean regions where excess macronutrients are present, phytoplankton growth is limited by the bioavailability of iron supplied to these areas primarily within atmospheric aerosols of crustal origin. However, processes that control the abundance of biologically accessible iron in these aerosols are largely unknown. Here we show that dissolution of ferrihydrite, a surrogate iron(oxy)hydroxide phase found in atmospheric waters, is enhanced in the presence of methanesulfinic acid (MSIA, CH3SO2H, a dimethylsulfide (DMS) oxidation intermediate) in laboratory irradiation experiments with aqueous suspensions that simulate marine aerosol particles. The increased release of soluble Fe(II) is attributed to a species specific and direct photochemical reduction rather than a proton‐promoted effect, and suggests an efficient mechanism by which iron‐starved phytoplankton can actively increase aerosol iron‐bioavailability by increasing DMS emissions
