It is quite clear that the political instability generated by the events of 1987 and 2000 gave greater impetus to the emigration process. Prior to 1987, emigration levels averaged around 2,460. However, thereafter, emigration levels soared to more than 5,000 annually, before falling to around 4,600 in 1992. The number of people moving abroad rose steadily from 1993 onwards, reaching a record hi...

Although Solidarność was the largest mass movement in history of after-war Europe, experience solidarity during that time communist Poland has barely been analysed. Drawing on historical accounts events 1980s and press interviews with members, this paper attempts to bridge gap identifies key aspects experienced solidarity. It argues under communism derived not only from common enemy – party sta...

Respiratory disorders are associated with occupational and environmental exposures. The latency period between exposure and disease onset remains uncertain. The World Trade Center (WTC) disaster presents a unique opportunity to describe the latency period for obstructive airway disease (OAD) diagnoses. This prospective cohort study of New York City firefighters compared the timing and incidence...

OBJECTIVE There is little evidence whether sudden cardiac death (SCD) is increasing in Asia, although the incidence of coronary heart disease among urban middle-aged Japanese men has increased recently. We examined trends in the incidence of SCD and its risk factors in the Circulatory Risk in Communities Study. DESIGN AND SETTING This was a population-based longitudinal study. Surveillance of...

Nonphysician clinicians (NPCs) are becoming increasingly prominent as health care providers. This study examines 10 such disciplines: nurse practitioners (NPs), physician assistants (PAs), nurse-midwives, chiropractors, acupuncturists, naturopaths, optometrists, podiatrists, nurse anesthetists, and clinical nurse specialists. The aggregate number of NPCs graduating annually in these 10 discipli...

After a steady increase since the 1950s, laryngeal cancer mortality had tended to level off since the early 1980s in men from most European countries. To update trends in laryngeal cancer mortality in Europe, age-standardized (world standard) mortality rates per 100,000 were derived from the WHO mortality database for 33 European countries over the period 1980-2001. Jointpoint analysis was used...

The mechanism by which gauge and gravitational anomalies cancel in certain string theories is reviewed. The presentation is aimed at theorists who do not necessarily specialize in string theory. Talk presented at 2001: A Spacetime Odyssey – the inaugural conference of the Michigan Center for Theoretical Physics

After years of efforts to push the LEP performance to, and indeed beyond, the limits of what had been believed possible, hints of a signal of a Higgs boson at 115GeV/c appeared in June 2000, were confirmed in September, and confirmed again in November. Spending an additional six-month period with LEP would have given the unambiguous opportunity of a fundamental discovery. Instead, this possibil...
