R&D INVESTMENT AND PRODUCTIVITY GROWTH IN U.S. AND CANADIAN FOOD MANUFACTURING

Productivity growth in the Canadian processed food industry has lagged behind that in the United States because of a relatively low rate of R&D investment. Although U.S. firms generally have a technological advantage over Canadian firms, marginal rates of return to R&D are higher in Canada.Agribusiness, Productivity Analysis,

The Use of Children\u27s Literature and Reflective Writing as a Means to Help Primary Elementary Students Cope with Natural Disaster

Natural disasters such as hurricanes, tornadoes, floods, tsunamis, and earthquakes frequently happen across the world. Many of these natural disasters bring destruction to homes, loss of loved ones, and emotional or physical trauma. For children who are still developing coping skills, these natural disasters can bring them emotional distress because they are unable to processes their experiences in a healthy way. In a review of literature on the topic of bibliotherapy and reflective writing to help children learn coping skills, I discovered a need for these processes to be introduced in normal settings, such as school and home, to help children who have experienced natural disasters develop coping skills. My goal in conducting this research was to create a resource that includes a variety of children\u27s literature on the topic of a natural disaster and that demonstrates a coping skill for that trauma. Guiding questions and reflective writing prompts were also added to this resource for the users to guide children in identifying and learning the demonstrated, healthy coping skills. I selected twenty-one quality and award-winning books that address natural disaster for review. Nineteen of them demonstrated a healthy coping skill within the book. Using the information from the book, I created guiding questions and reflective writing prompts to help guide the children in connecting with and learning how to use the coping skill demonstrated. Future developments from my research may include a website with the resource information or a hard copy that can be sent to areas of high-need or high-risk for natural disaster. My goal is that my resource will foster healthy coping skills for children in the school setting, home, or alongside professional help

Space shuttle food system summary, 1981-1986

All food in the Space Shuttle food system was precooked and processed so it required no refrigeration and was either ready-to-eat or could be prepared for consumption by simply adding water and/or heating. A gun-type water dispenser and a portable, suitcase-type heater were used to support this food system during the first four missions. On STS-5, new rehydratable packages were introduced along with a needle-injection water dispenser that measured the water as it was dispensed into the packages. A modular galley was developed to facilitate the meal preparation process aboard the Space Shuttle. The galley initially flew on STS-9. A personal hygiene station, a hot or cold water dispenser, a convection oven, and meal assembly areas were included in the galley

Multi-sensor Testing for Automated Rendezvous and Docking

During the past two years, many sensors have been tested in an open-loop fashion in the Marshall Space Flight Center (MSFC) Flight Robotics Laboratory (FRL) to both determine their suitability for use in Automated Rendezvous and Docking (AR&D) systems and to ensure the test facility is prepared for future multi-sensor testing. The primary focus of this work was in support of the CEV AR&D system, because the AR&D sensor technology area was identified as one of the top risks in the program. In 2006, four different sensors were tested individually or in a pair in the MSFC FRL. In 2007, four sensors, two each of two different types, were tested simultaneously. In each set of tests, the target was moved through a series of pre-planned trajectories while the sensor tracked it. In addition, a laser tracker "truth" sensor also measured the target motion. The tests demonstrated the functionality of testing four sensors simultaneously as well as the capabilities (both good and bad) of all of the different sensors tested. This paper outlines the test setup and conditions, briefly describes the facility, summarizes the earlier results of the individual sensor tests, and describes in some detail the results of the four-sensor testing. Post-test analysis includes data fusion by minimum variance estimation and sequential Kalman filtering. This Sensor Technology Project work was funded by NASA's Exploration Technology Development Program

A meta-analysis of rates of return to agricultural R & D: ex pede Herculem?

IFPRI has long argued that spending on agricultural research constitutes a sound investment in poverty reduction and agricultural and economic growth, through improvements in productivity. This argument is based partly on the reported evidence of high rates of return to agricultural research, typically believed to be in the range of 40–60 percent per year. Yet there continues to be controversy over whether these figures are to be believed, and over what they actually indicate. This study represents the first attempt to take a comprehensive look at all the available evidence on rates of return to investments in agricultural R&D since 1953, and the only attempt to do so in a formal statistical fashion. This report has compiled and documented the literature in ways that make it more accessible and more useful to other researchers and policymakers, as well as others interested in the evidence. The analysis reveals some systematic patterns and some sources of biases that make it easier to interpret the evidence and draw meaningful conclusions.

Relative Number and Distribution of Murine Hypothalamic Proopiomelanocortin Neurons Innervating Distinct Target Sites

Proopiomelanocortin (POMC) neurons send projections widely throughout the brain consistent with their role in regulating numerous homeostatic processes and mediating analgesia and reward. Recent data suggest that POMC neurons located in the rostral and caudal extents of the arcuate nucleus of the hypothalamus may mediate selective actions, however it is not clear if POMC neurons in these regions of the arcuate nucleus innervate specific target sites. In the present study, fluorescent microspheres and cholera toxin B were used to retrogradely label POMC neurons in POMC-DsRed transgenic mice. The number and location of POMC cells projecting to the supraoptic nucleus, periaqueductal gray, ventral tegmental area, paraventricular nucleus, lateral hypothalamic nucleus, amygdala and the dosal vagal complex was determined. Tracer injected unilaterally labeled POMC neurons in both sides of the arcuate nucleus. While the total number of retrogradely labeled cells in the arcuate nucleus varied by injection site, less than 10% of POMC neurons were labeled with tracer injected into any target area. Limited target sites appear to be preferentially innervated by POMC neurons that reside in the rostral or caudal extremes of the arcuate nucleus, whereas the majority of target sites are innervated by diffusely distributed POMC neurons. The modest number of cells projecting to each target site indicates that relatively few POMC neurons may mediate potent and specific physiologic responses and therefore disturbed signaling in a very few POMC neurons may have significant consequences

Determination of Interface Atomic Structure and Its Impact on Spin Transport Using Z-Contrast Microscopy and Density-Functional Theory

We combine Z-contrast scanning transmission electron microscopy with density-functional-theory calculations to determine the atomic structure of the Fe/AlGaAs interface in spin-polarized light-emitting diodes. A 44% increase in spin-injection efficiency occurs after a low-temperature anneal, which produces an ordered, coherent interface consisting of a single atomic plane of alternating Fe and As atoms. First-principles transport calculations indicate that the increase in spin-injection efficiency is due to the abruptness and coherency of the annealed interface.Comment: 16 pages (including cover), 4 figure

Hippie Homesteaders: Art, Crafts, Music, and Living on the Land in West Virginia

It’s the 1960s. The Vietnam War is raging and protests are erupting across the United States. In many quarters, young people are dropping out of society, leaving their urban homes behind in an attempt to find a safe place to live on their own terms, to grow their own food, and to avoid a war they passionately decry. During this time, West Virginia becomes a haven for thousands of these homesteaders—or back-to-the-landers, as they are termed by some. Others call them hippies. When the going got rough, many left. But a significant number remain to this day. Some were artisans when they arrived, while others adopted a craft that provided them with the cash necessary to survive. Three panel presenters will tell their stories of the movement and the times. They came to the state, lived on the land, and created successful careers with their craft. Tom & Connie McColley made baskets coveted by the Smithsonian Institution’s Renwick Gallery. Photographer Ric MacDowell came as a VISTA volunteer, and dancer Jude Binder transplanted an entire commune to the hills of West Virginia. Along with these stories, Carter Taylor Seaton, the author of newly published Hippie Homesteaders, will examine the serendipitous timing of this influx and the communal and economic support these crafters received from residents and state agencies in West Virginia and present her argument that this movement lead to the formation of Tamarack, and the birth of Mountain Stage
