A decade ago, in July 1990, the Australian economy had just entered a severe recession. Real GDP slowed in the first half of 1990, and then began to fall in the second half of the year. The rate of unemployment in mid 1990 was around 63/4 per cent but rose sharply in the following year. The rate of inflation was around 6 per cent, but was about to decline quickly, to levels not seen since the e...

Objective- To measure statistically bone cortex to diameter  (C/D) ratio in metocarpo/metatarsal and proximal phalanges in camel. This ratio may be used in diagnosing possible metabolic and nutritional diseases in camel. Design- Experimental study. Animals- Twelve camel limbs (6 fore limbs & 6 hind limbs)      Procedures- This study was conducted on dorsopalmar/dorsoplantar radiographs of t...

Lanzhou is one of the most polluted cities in China. Sulfur dioxide (SO2) concentrations have shown evident seasonal variability. Pollution was generally within the second-level criterion (b0.15mgm) in spring, summer, and fall but wasmuch higher than the second-level criterion and sometimes reaches mid-level pollution (APIN200) in winter. Meteorological conditions (low winds, stable stratificat...

Using three meteorological reanalyses and three outgoing long-wave radiation (OLR) datasets, we show that the Hadley circulation has a significant expansion of about 2 to 4.5 degrees of latitude since 1979. The three reanalyses all indicate that the poleward expansion of the Hadley circulation in each hemisphere occurs during its summer and fall seasons. Results from the OLR datasets do not hav...

This chapter provides an overview of how a powerful acoustical principle – sympathetic resonance – has been applied to our organ of hearing. It focuses on the principle’s virtues, drawbacks, and varying fortunes. Why did Helmholtz’s resonance theory of hearing in the 1850s fall from universal acceptance to near total disregard? What were the factors favouring traveling wave theories, most notab...

Plasma levels of progesterone were determined from serial samples taken from 2 black bears over 3 consecutive fall periods. Each animal was pregnant during the 1st and 3rd years. Variations in progesterone levels were seen between animals and within each animal between pregnancies. Average baseline levels during the mid-to-late preimplantation period were 5.0-12.5 ng/ml and increased 2-3 fold a...

Objective: In recent years, various treatment programs have been implemented in Iran aimed at rehabilitation and improvement of drug-dependent patients but so far, few studies have been conducted on the effectiveness of different treatment programs in terms of different outcomes. This study was conducted to determine the differences among patients participating in three therapeutic programs, ou...

The U.S. Department of Commerce’s Bureau of Economic Analysis (BEA) is changing its method of measuring the growth of the U.S. economy. Shifts in the structure of the economy—particularly the spectacular fall in computer prices—have meant that BEA’s traditional “fixed-base-year” method of tracking the nation’s gross domestic product (GDP) has tended to overstate growth in recent years. As a res...

Why did the stock market decline so much in the early 1970’s and remain low until the early 1980’s? We argue that it was because information technology arrived on the scene and the stock-market incumbents of the day were not ready to implement it. Instead, new firms would bring in the new technology after the mid-1980’s. Investors foresaw this in the early 1970’s and stock prices fell right awa...

Using factor methods, we decompose industrial production (IP) into components arising from aggregate and sector-specific shocks. An approximate factor model finds that nearly all of IP variability is associated with common factors. We then use a multisector growth model to adjust for the effects of input-output linkages in the factor analysis. Thus, a structural factor analysis indicates that t...
