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

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

Directors of healthcare organizations normally owe fiduciary duties to their shareholders or, in the case of nonprofits, to the charitable mission of the organization. As an organization descends to bankruptcy, however, the board's duties may shift. At some point, the board may be imposed with different and often conflicting obligations to the corporate enterprise as a whole, with a primary criterion being the interests of creditors. In this article, the authors analyze the murky areas of the Zone and give guidance as to when the board's duty may shift-and as to how directors should proceed both in determining their duties and in working to fulfill them. 相似文献

An accidental atypical hanging with the collar of a sweater is reported. A 67-year-old man was found dead in the sitting position with the collar of his sweater hanging off the brake handle of a motorcycle. Autopsy findings revealed a ligature mark on the surface of the neck; hemorrhages in the sternohyoid muscles; submucosal hemorrhages in the left greater horn of the hyoid bone; a large degree of submucosal petechial hemorrhages in the larynx, oral mucosa, and palpebral conjunctivae; and dark-red liquid blood with little clotting in the heart cavities. The alcohol levels in the blood and urine were 2.84 mg/ml and 3.52 mg/ml, respectively. It was concluded that the man had died from hanging by the sweater, and it was speculated that when he became inebriated, he might have lost consciousness and then fell with the collar of his sweater hanging from the brake handle of the motorcycle. 相似文献

We investigate the intergenerational welfare implications of Generational Accounting when it is used as the basis for intertemporal fiscal policy decisions. In particular, we consider an economy with a PAYGO social security system out of steady state due to a permanent fall in fertility. In a highly stylized CGE overlapping generations model we illustrate that policy recommendations based on a standard application of Generational Accounting may not be compatible with intertemporal welfare maximization. Our model provides an example where such policies are either time inconsistent or welfare-decreasing. 相似文献
