The article analyzes the spatial location behavior of economic activity that is knowledge based, by decomposing the Knowledge-based
Economy Index developed by the OECD (1999) and elaborated by Cooke and Schwartz (2003) into major components that represent
groups with different characteristics. The spatial behavior is analyzed in Israel in the years 1995–2002. We find that business
services and high tech services tend to concentrate in metropolitan areas. Business services are found in the main city and
high tech services in the satellite urban ring, with the outer-cities becoming stronger over time. Public services supporting
the knowledge-based economy are concentrated in the center of the country, though not necessarily in the principal city, and
they can represent an important tool in regional policy. The high tech manufacturing is concentrated around the big cities,
mainly around the main metropolis. The other knowledge-based manufacturing activities tend to leave for the periphery. 相似文献

Laboratory investigation of deaths due to anaphylaxis. 总被引:11,自引:0,他引:11

To establish a useful laboratory protocol to investigate possible cases of fatal anaphylaxis, we measured mast-cell-derived tryptase levels and allergen-specific immunoglobulin E (IgE) antibody levels in sera obtained prior to or within 24 h after death from 19 anaphylaxis victims. Elevated serum tryptase levels (range = 12 ng/mL to 150 micrograms/mL) were found in nine of nine Hymenoptera sting fatalities, six of eight food-induced fatalities, and two of two reactions to diagnostic therapeutic agents. Tryptase levels were normal (less than 10 ng/mL) in 57 sequential sera obtained postmortem from six control patients. Tryptase could not be measured in pleural or pericardial fluids for technical reasons. Serum IgE antibodies were elevated in five of the nine Hymenoptera sting fatalities and in eight of the eight fatal food reactions; assays were unavailable for the two diagnostic/therapeutic agents. If elevated, the victim's serum IgE antibodies to food could be used to identify allergens in uneaten portions of foods consumed shortly before the anaphylactic event. IgE antibodies were moderately stable during storage in a variety of anticoagulants at room temperature for up to 11 weeks. Elevated mast-cell-derived tryptase levels in postmortem sera reflect antemortem mast cell activation and may be used as a marker for fatal anaphylaxis. If assays are available for IgE antibodies to relevant allergens, such assays provide evidence for antemortem sensitization; these assays may be modified to identify allergens in foods consumed by victims of food-induced anaphylaxis. 相似文献

In 2012, the simultaneous elections at the federal, state and municipal levels in Mexico reopened the debate about the path of democratic consolidation in the country. With the return of the Revolutionary Institutional Party to the presidency in 2013, there are renewed signs that Mexican democratic consolidation is underway. Particularly important in this process is that the 2012 gubernatorial and mayoral elections have been more competitive, resulting in higher political alternation in power between political parties. Under a changing subnational political context, there are indications that subnational politicians are no longer under the shadow of a dominant party system. As a more consolidated federal democracy, the political landscape in Mexico has become more complex. 相似文献

Food insecurity, or limited or uncertain availability of nutritionally adequate and safe foods or limited or uncertain ability to acquire acceptable foods in socially acceptable ways, affects more than 10% of Americans. The U.S. Department of Agriculture's 18‐item Household Food Security Survey Module (HFSSM) is the most common measure used in the United States to assess food insecurity. This measure is to be completed by one adult who reports on the severity of disruptions in the quality and quantity of the household food supply. Recent work suggests that men and women might respond differently to some of the items in this measure. Therefore, the aim of the current study was to further explore how men and women interpret each of the items and specific concepts in this measure. Pairs (n = 25) of low‐income and food‐insecure mothers and fathers of children aged 2.5–10 years participated in one‐on‐one interviews to answer the HFSSM questions using the think‐aloud method. The data were analyzed using basic inductive qualitative methods, and the findings suggest that gender is related to interpretation of key concepts relevant to food insecurity including “household,” “balanced meal,” and “worry.” These findings have policy implications for the use of this measure as a national benchmark of food insecurity such as the potential need for an additional, complementary instrument to include several male reference questions with different terminology. 相似文献

ABSTRACTThis article explores the motivations behind the applications for Portuguese citizenship by Turkish Jews since 2015. Based on a qualitative research, the findings highlight that obtaining a second passport does not yet equate emigration. Rather, it constitutes an insurance policy aimed at alleviating growing ontological insecurity, stemming partly from their secular and westernized lifestyle and from their Jewish identity, which are endangered by perceived de-secularisation, growing anti-Semitism and authoritarian trends in Turkey. 相似文献

The aim of this paper is to analyze the influence of the legal and institutional environment on bidder firm returns around the announcement date of cross-border Mergers and Acquisitions (M&As). The database includes 469 M&As of European (221 cross-border and 248 domestic) listed firms, with target firms being worldwide public or private firms (40 countries), over the 2002–2006 period.Shareholders of acquiring firms place greater value on cross-border M&A announcements than on domestic ones. The stronger (weaker) the legal and institutional environment of the acquirer firm country in comparison with that of the target firm country, the more positive (negative) the effect on acquiring-firm shareholders’ valuation of M&As. 相似文献
