Mackay Research, prominent in qualitative Australian social research since the early 1980's, has produced two reports on Australian attitudes towards multiculturalism in Australia, the first in 1985, entitled The Multiculture and the second, Multiculturalism, in September this year. This paper compares findings from these two reports, indicates some directions of attitudinal change in the prece...
The progress of semiconductor physics in the decade 1970-1980 is connected with gradual deviation from the electronic band structure of ideal crystal of Bloch picture (Bloch, 1928) where, unlike atomic world with its discrete and precisely defined, in the limits of uncertainty relation, energy levels, energy of bound electron is a multivalued function of momentum in the energy band and density ...
BACKGROUND Excess bodyweight is a major public health concern. However, few worldwide comparative analyses of long-term trends of body-mass index (BMI) have been done, and none have used recent national health examination surveys. We estimated worldwide trends in population mean BMI. METHODS We estimated trends and their uncertainties of mean BMI for adults 20 years and older in 199 countries...
Albumin emerged as a biocatalyst in 1980 and the continuing interest in this protein is proved by numerous papers. The use of albumin was initially confined to the field of asymmetric oxidations and reductions, but more recently it has found a broader application to chemical reactions such as additions, condensations and eliminations. This review reports the main applications of albumin in orga...
The field of Artificial Intelligence (AI) began in a blaze a glory. Within a decade or so of its inception, computers were solving geometry and physics problems at a college freshman level, playing chess like regional champions, diagnosing serious illnesses on par with expert physicians and designing complex VLSI circuits. No problem was too complex, but, as AI researchers discovered in the 198...
Abstract Rising income inequality is a critical problem in both the global North and South. In United States, Gini coefficient measuring nationwide rose from 0.403 1980 to 0.480 2014 (US Census), residential segregation by has increasingly occurred many metropolitan regions particularly reflected spatial separation of wealthiest households. This chapter focuses on change level Los Angeles regio...
The US financial sector has become a magnet for the brightest graduates in science, technology, engineering and mathematical fields (STEM). We provide quantitative bases this anecdotal fact US, over period 1980–2019 with specific focus on last decade where information major of study is available. First, we show that long-run educational upgrading finance was biased towards STEM graduates, espec...
Comprehensive research on glacier changes in the Tian Shan is available for the current decade; however, there is limited information about glacier investigations of previous decades and especially before the mid 1970s. The earliest stereo images from the Corona missions were acquired in the 1960s but existing studies dealing with these images focus on single glaciers or small areas only. We de...
Since 1980, over 2,000 local governments in US Atlantic states have been hit by a hurricane. We study government fiscal dynamics the aftermath of hurricanes. These shocks reduce tax revenues, public expenditures, and debt financing decade following Hurricanes create collateral damage for increasing cost at critical moments after strike. Municipalities with 1 standard deviation-above-average rac...
The rate of nosocomial bacteremia due to Staphylococcus aureus has increased over the past decade, but trends in community-acquired S. aureus bacteremia are less certain. This hospital-based observational study compares nosocomial and community-acquired S. aureus bacteremias during 1980-1983 and 1990-1993. The rate of nosocomial S. aureus bacteremia increased from 0.75 to 2.80 cases per 1,000 d...
