Assessing the use of Geographical Indications for the New England wine region in NSW
Geographical Indications (GIs) have increasingly been used as a marketing tool to create an image of quality and uniqueness, and so capture premium prices. Hedonic pricing studies have shown that indication of geographical origin of production (e.g. country, region, wineries, and location), can affect prices. However, Geographical Indications only work when they are backed up by quality products. The objectives of this study are to assess the potential of a proposed Geographical Indication for the emerging "New England" wine region in promoting local wines and to make recommendations on how that potential, if it exists, can be realised. The assessment is based on an overview of existing systems of Geographical Indications and conditions, both economic and regulatory, which are required for successful geographical indication applications.geographical indication, TRIPS Agreement, wine marketing, hedonic, Agribusiness,

Extension Circular 71-1528 is about cattle grubs. Cattle grubs are immature or larval stages of warble flies
Perceptions of peer support for victim-survivors of sexual violence and abuse:an exploratory study with key stakeholders
Experiences of sexual violence, childhood sexual abuse, and sexual assault are common across all societies. These experiences damage physical and mental health, coping ability, and relationships with others. Given the breadth and magnitude of impacts, it is imperative that there are effective, accessible services to support victim-survivors, ease suffering, and empower people to cope, recover and thrive. Service provision for this population in the United Kingdom is complex and has been hit substantially by austerity. Since positive social support can buffer against negative impacts, peer support may be an effective approach. The aim of this exploratory study was to capture the views and perspectives of professional stakeholders concerning service provision for victim-survivors, particularly perceptions of peer support. In-depth semistructured interviews were conducted in the UK during 2018 with six professional stakeholders, highly experienced in the field of service provision for victim-survivors of sexual violence and abuse. An abductive approach to analysis was used, applying principles from thematic analysis. Our sample comprised four females and two males, and their roles included psychiatrist, general practitioner, service improvement facilitator, and senior positions within victim-survivor organizations. Interviews highlighted models of peer support for this population, good practice and safety considerations, and a lack of uniformity regarding quality and governance standards across the sector. Findings indicated that current funding models impact negatively on victim-survivor services, and that provision is fragmented and insufficient across statutory and not-for-profit sectors. The influence of the medical model upon service provision was evident, which resulted in apprehension around support delivered in less-usual formsâincluding peer support. Further research is needed to explore the potential of peer support for victim-survivors of sexual violence and abuse
Spatial patterns of soil nitrification and nitrate export from forested headwaters in the northeastern United States
Nitrogen export from small forested watersheds is known to be affected by N deposition but with high regional variability. We studied 10 headwater catchments in the northeastern United States across a gradient of N deposition (5.4 - 9.4 kg ha-1 yr-1) to determine if soil nitrification rates could explain differences in stream water NO 3- export. Average annual export of two years (October 2002 through September 2004) varied from 0.1 kg NO3--N ha-1 yr-1 at Cone Pond watershed in New Hampshire to 5.1 kg ha-1 yr-1 at Buck Creek South in the western Adirondack Mountains of New York. Potential net nitrification rates and relative nitrification (fraction of inorganic N as NO3-) were measured in Oa or A soil horizons at 21-130 sampling points throughout each watershed. Stream NO3- export was positively related to nitrification rates (r2 = 0.34, p = 0.04) and the relative nitrification (r2 = 0.37, p = 0.04). These relationships were much improved by restricting consideration to the 6 watersheds with a higher number of rate measurements (59-130) taken in transects parallel to the streams (r 2 of 0.84 and 0.70 for the nitrification rate and relative nitrification, respectively). Potential nitrification rates were also a better predictor of NO3- export when data were limited to either the 6 sampling points closest to the watershed outlet (r2 = 0.75) or sampling points \u3c250 m from the watershed outlet (r2 = 0.68). The basal area of conifer species at the sampling plots was negatively related to NO3- export. These spatial relationships found here suggest a strong influence of near-stream and near-watershed-outlet soils on measured stream NO3- export. Copyright 2012 by the American Geophysical Union
Outstanding Business Reference Sources: The 2010 Selection of Recent Titles
Each year at the ALA Annual Conference, the Business Reference Sources Committee of RUSAâs Business Reference and Services Section (BRASS) meets to select the outstanding business reference sources published since May of the previous year. With all due respect to the familiar and longstanding column title, committee members have come to think of our charge more broadly as finding the most outstanding business information sources, the better to reflect the evolving nature of the formats and means of accessing business information to meet reference needs. For 2010, the committee weeded titles proposed during 2009â10 down to fifteen that made the final review. Among those, the committee selected three as outstanding business information titles and an additional six as noteworthy titles. The works reviewed below cover such areas as economics, the music industry, corporate sustainability, retailing, brand valuation, the current and historical U.S. role in international trade, and an innovative new vehicle for affordable (or free) online access to premier instructional resources in business and economics
Species-dependent regulation of monocyte/macrophage Ia antigen expression and antigen presentation by prostaglandin E
The expression of Ia antigen by various murine and human macrophage populations and the ability of prostaglandins of the E series to regulate Ia antigen expression were explored. Monocytes and macrophages from human and murine populations demonstrated a dichotomy in the expression of Ia antigen. Both human monocytes and macrophages expressed elevated levels of Ia antigen compared to their murine counterpart. Murine macrophages appear to express elevated levels of Ia antigen only when actively interacting with T lymphocytes in vivo or with lymphokines in vitro. Prostaglandins of the E series can suppress murine macrophage Ia antigen expression, but have little effect on the expression of Ia antigen by human monocytes and macrophages. Also, prostaglandins of the E series do not modulate the ability of human monocytes to present antigen to autologous lymphocytes when studied over a broad concentration range. These data suggest that prostaglandin E compounds do not profoundly affect human monocyte/macrophage Ia antigen expression or human monocyte antigen presenting activity.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26359/1/0000446.pd
Outstanding Business Reference Sources: The 2011 Selection of Recent Titles
Each year, the Business Reference Sources Committee of BRASS selects the outstanding business reference sources published since May of the previous year. The committee reviewed 31 entries; 3 were designated as âoutstanding,â and 7 were placed into the other noteworthy titles category. Of the 7 noteworthy titles, 2 were labeled as significant new editions. These works cover a variety of topics: industrial/organizational psychology, leadership, law and finance, economic history, marketing and demographics, as well as operations research and management science
A nonlinear hydrodynamical approach to granular materials
We propose a nonlinear hydrodynamical model of granular materials. We show
how this model describes the formation of a sand pile from a homogeneous
distribution of material under gravity, and then discuss a simulation of a
rotating sandpile which shows, in qualitative agreement with experiment, a
static and dynamic angle of repose.Comment: 17 pages, 14 figures, RevTeX4; minor changes to wording and some
additional discussion. Accepted by Phys. Rev.
