    This research shows that approximately 29 percent of lettuce purchases in California expect to purchase an organically grown lettuce product in the future. Organic lettuce purchasers are more likely to be female, have a higher household income and a higher level of education. Consumers are concerned with the freshness, quality, price, and environmental impact of the lettuce they purchase.Consumer/Household Economics,

    Robust High-Dynamic-Range Vector Magnetometry via Nitrogen-Vacancy Centers in Diamond

    Full text link
    We demonstrate a robust, scale-factor-free vector magnetometer, which uses a closed-loop frequency-locking scheme to simultaneously track Zeeman-split resonance pairs of nitrogen-vacancy (NV) centers in diamond. Compared with open-loop methodologies, this technique is robust against fluctuations in temperature, resonance linewidth, and contrast; offers a three-order-of-magnitude increase in dynamic range; and allows for simultaneous interrogation of multiple transition frequencies. By directly detecting the resonance frequencies of NV centers aligned along each of the diamond's four tetrahedral crystallographic axes, we perform full vector reconstruction of an applied magnetic field

    A Question of Respect: A Qualitative Text Analysis of the Canadian Parliamentary Committee Hearings on The Protection of Communities and Exploited Persons Act

    We evaluate the Canadian parliamentary hearings on The Protection of Communities and Exploited Persons Act to determine whether respectful and fair deliberation occurred.  Our focus is on the content, tone, and nature of each question posed by committee members in hearings in both chambers.  We find that, on the whole, the vast majority of questions met this baseline, but that committee members were biased toward witnesses in agreement with their position and against witnesses in opposition to it.  In addition to our substantive findings, we contribute methodological insights, including a coding scheme, for this kind of qualitative text analysis

    Nicole Flynn is a contributing author, Clockwork Women: Termporality and Form in Jean Rhys\u27s Interwar Novels. , pp.41-65. Rhys Matters, the first collection of essays focusing on Rhys\u27s writing in over twenty years, encounters her oeuvre from multiple disciplinary perspectives and appreciates the interventions in modernism, postcolonial studies, Caribbean studies, and women\u27s and gender studies.https://openprairie.sdstate.edu/english_book/1011/thumbnail.jp

    Los Colores de la edad

    La vejez ecuatoriana está a punto de convertirse en la población más importante del país en las siguientes décadas. El estado está elaborando planes para establecer la infraestructura de apoyo que necesitará la población de ancianos que está creciendo, pero es importante que entendamos cómo ayudarlos de la manera más adecuada. La tradición del cuidado en la casa de los hijos está cambiando, pero no es necesariamente un retraso si es que en otro lugar encuentran la compañía, el amor y las amistades que necesitan. Dentro de un asilo de ancianos es posible crear estas características si uno recrea en si una familia, una comunidad y, un sistema de apoyo y cariño con los que participan ahí. La familia mantiene su puesto en el centro de la cultura ecuatoriana y, es con este valor familiar que deberíamos desarrollar la forma nueva del cuidado para los adultos mayores. En la Casa de Acogida San Vicente de Paul han logrado establecer esta familia cariñosa dentro de sus paredes, y se refleja en las ancianas mismas que esto les ayuda a sentirse amadas, valoradas y con algo todavía para dar a los demás. No hay que dejarles sin este valor propio. Esta monografía intenta explicar lo que las mujeres de San Vicente de Paul realmente necesitan y buscan en su vejez. Presenta los elementos que hacen posible realizar sus sueños con el apoyo de otros. Sus historias cuentan con una voz de cariño y esfuerzo, la realidad dura de sus vidas al lado de momentos de alegría y compasión. Expresan el significado de lo que necesitan, y esperan que los lectores de sus historias puedan comprender mejor el cuidado más adecuado que necesitan en sus últimos años

    Synthetic, Structural and Computational Studies on Heavier Tetragen and Chalcogen Triazenide Complexes

    The syntheses of the triazenide complexes [{N(N Dipp) 2} 2M] (Dipp = 2,6-di-isopropylphenyl; M = Ge(II) (1), Sn(II) (2), Pb(II) (3), and Te(II) (5)) are described for the first time. These compounds have been characterized by single-crystal X-ray diffraction and heteronuclear NMR spectroscopy. Density functional theory calculations were employed to confirm the presence and nature of the stereochemically active lone pairs in 1-5, alongside the Gibbs energy changes for their general synthesis, which enable the rationalization of observed reactivities. </p

    Directly pumped 10  GHz microcomb modules from low-power diode lasers

    Soliton microcombs offer the prospect of advanced optical metrology and timing systems in compact form factors. In these applications, the pumping of microcombs directly from a semiconductor laser without amplification or triggering components is desirable to reduce system power and to simplify system design. At the same time, low-repetition-rate microcombs are required in many comb applications as an interface to detectors and electronics, but their increased mode volume makes them challenging to pump at low power. Here 10 GHz repetition rate soliton microcombs are directly pumped by low-power (<20  mW) diode lasers. High-Q silica microresonators are used for this low-power operation and are packaged into fiber-connectorized modules that feature temperature control for improved long-term frequency stability
