Despite decades of research on social capital, studies that explore the relationship between political institutions and generalized trust-a key element of social capital-across time are sparse. To address this issue, we use various cross-national public-opinion data sets including the World Values Survey and employ pooled time-series OLS regression and fixed- and random-effects estimation techn...

This article provides an economic assessment of federal regulatory policy toward airplane noise as encapsulated in the 1990 Airport Noise and Capacity Act (ANCA). This act mandated the elimination of certain aircraft, such as the Boeing 727 and DC-9, from all U.S. airports by the end of 1999 to meet quieter noise requirements. We find that the present discounted benefits of the ANCA, reflected ...

background: noise induced hearing loss (nihl) is the highest reported occupational disease among industrial workers but there is scarcity of data on disease burden in malaysia. this study estimated the risks and burden of nihl in manufacturing industries in malaysia. methods: this cross-sectional industrial survey was conducted by interviewing osh practitioners at 26 industries categorized as f...

T his feature explores the operation of individual markets. Patterns of behavior in markets for specific goods and services offer lessons about the determinants and effects of supply and demand, market structure, strategic behavior, and government regulation. Suggestions for future columns and comments on past ones should be sent to James R. Hines Jr., c/o Journal of Economic Perspectives, Depa...

Power transformers can be sources of disturbing and annoying acoustic noise. This paper is a first phase report of a wider framework of study that investigates the noise radiation characteristics of air-cooled power transformers. The dynamics of the transformer core structure plays a significant role in the noise generation process. The reported work focuses on the influence of lamination of th...

Correct inference of genetic regulations inside a cell is one of the greatest challenges in post genomic era for the biologist and researchers. Several intelligent techniques and models were already proposed to identify the regulatory relations among genes from the biological database like time series microarray data. Recurrent Neural Network (RNN) is one of the most popular and simple approach...

The debate over the impact of government regulation on innovation in the United States is framed in the context of the gradual decline of economic regulation since the 1960s, and the gradual increase in social welfare regulation over the same period. Fueling much of the economic deregulation movement has been classical economic theory, which holds that regulation imposes a cost burden on firms,...

Indoors wireless infrared transmission is severely impaired by ambient noise. In addition, in a multiple user network, since many users share the same physical channel, considerable amount of multi-user interference will also be introduced. In this paper, Infrared CDMA techniques are proposed to combat the effect of ambient and multi-user interference. Our analysis is based on Photon-Counting a...

Noise generated from technical devices is an increasingly important problem. Jet engines in particular produce sound levels that are not only a nuisance, but may also impair hearing. The noise emitted by such engines is generated by different sources, such as jet exhaust, fans or turbines, and combustion. Increasing restrictions on the allowable noise-emission levels force manufacturers to desi...
