Managerial Stress In Hong Kong And Taiwan : A Comparative Study, Oi Ling Siu, Luo Lu, Cary L. Cooper

Centre for Public Policy Studies : CPPS Working Paper Series

The purpose of this study was to investigate occupational stress in managers in Hong Kong (N=280) and Taiwan (N=347) using the Occupational Stress Indicator-2 (OSI-2). The results showed that the reliabilities and predictive validity of the OSI-2 subscales were reasonably high in both samples. The logical relationships between job satisfaction, mental and physical well-being that were found in the two samples have provided support to the findings obtained in Western countries. The predictors for health effects were various and many in the two places. Further, there were gender differences in managerial stress in Hong Kong: female managers scored higher in …

From 1996 June 10 to July 29, the International Ultraviolet Explorer monitored the Seyfert 1 galaxy NGC 7469 continuously in an attempt to measure time delays between the continuum and emission-line fluxes. From the time delays, one can estimate the size of the region dominating the production of the UV emission lines in this source. We find the strong UV emission lines to respond to continuum variations with time delays of about 2_.^d3-3_.^d1 for Lyα, 2_.^d7 for C _IV λ1549, 1_.^d9-2_.^d4 for N _IV λ …

Seismic Response Of Asymmetric Systems: Energy-Based Approach, Rakesh K. Goel

Civil and Environmental Engineering

An energy-based approach has been used to investigate the seismic behavior of code-designed asymmetric-plan systems. The systems considered in this investigation had large eccentricities in both directions, were designed for bidirectional earthquake loading, and their responses were computed with both components of ground motion acting simultaneously. The presented results demonstrate that the total input energy is about the same whether the system plan is symmetric or asymmetric. Furthermore, flexible-side elements in asymmetric- plan systems may be more vulnerable to earthquakes than the same elements in symmetric-plan systems if they are not designed to accommodate the higher hysteretic-energy demands. This observation …

Earthquake Characteristics Of Bridges With Integral Abutments, Rakesh K. Goel

Civil and Environmental Engineering

Earthquake analysis of bridges requires that the period and damping ratio be determined for each significant mode of vibration. Data on these vibration properties, identified from motions of bridges recorded during actual earthquake events, provide the most direct means of verifying and improving the current guidelines. Thus, the aim of this investigation was to measure the vibration properties of a two-span concrete bridge from its motions recorded during actual earthquake events. These data were then used to investigate how abutment participation affected the vibration properties of bridges with integral abutments. It is shown that the vibration period elongated and the …

Subsidies In Oligopoly Markets: A Welfare Comparison Between Symmetric And Asymmetric Costs, Stephen F. Hamilton, Rickard Sandin

Economics

Oligopolistic industries generally produce less than is socially desirable. As a result, the use of production subsidies is often suggested as a means of raising production toward the efficient level in imperfectly competitive markets. In cases where firms are equally efficient in producing the good, the common prescription is a policy of uniform subsidization, as suggested by Besley (1989).(1) When firms in an industry differ in cost efficiency, however, uniform subsidization involves subsidizing inefficient firms in the same manner as efficient firms. Consequently, uniform policy may be undesirable from a social perspective, particularly when the price-cost margins of inefficient firms …

Period Formulas For Moment-Resisting Frame Buildings, Rakesh K. Goel, Anil K. Chopra

Civil and Environmental Engineering

Most seismic codes specify empirical formulas to estimate the fundamental vibration period of buildings. Evaluated first in this paper are the formulas specified in present U.S. codes using the available data on the fundamental period of buildings "measured" from their motions recorded during eight California earthquakes, starting with the 1971 San Fernando earthquake and ending with the 1994 Northridge earthquake. It is shown that, although the code formulas provide periods that are generally shorter than measured periods, these formulas can be improved to provide better correlation with the measured data. Subsequently, improved formulas for estimating the fundamental periods of reinforced …

Observational Evidence Of Wave Ducting And Evanescence In The Mesosphere, J. R. Isler, Michael J. Taylor, D. C. Fritts

All Physics Faculty Publications

A collaborative radar and imaging study of gravity waves over the Hawaiian Islands was performed during October 1993 as part of the Airborne Lidar and Observations of Hawaiian Airglow 1993/Coupling and Dynamics of Regions Equatorial (ALOHA-93/CADRE) campaign to investigate the propagation characteristics of short-period (<1 hour) waves at nightglow altitudes. The horizontal wavelengths and apparent phase speeds of quasi-monochromatic wave events were measured in four separate nightglow emissions using data obtained by a high-resolution CCD imager. This information was correlated with simultaneous MF radar wind measurements over the same height interval (∼80–100 km) to infer intrinsic wave parameters in each case. Correlating the two data sets allowed the determination of the local vertical wavenumber for each event, in particular whether it be real (indicative of freely propagating waves) or imaginary (indicative of ducted or evanescent waves). The results of this study indicate a preponderance of ducted or evanescent waves at 80–100 km during the time of the observations, with up to ∼75% of the events recorded exhibiting ducted or evanescent behavior. Also noted was a tendency for ducted behavior to be more prevalent among waves with shorter horizontal wavelengths, in agreement with Doppler ducting theory. These results suggest that ducted waves are relatively common in the upper mesosphere and lower thermosphere region, at least over the mid-Pacific Ocean. As small-scale waves which are ducted have the potential to travel much longer horizontal distances than freely propagating waves, the frequency of their occurrence should be taken into account in efforts to quantify gravity wave effects at these altitudes.

The General Well-Being Of Recreational Drug Users: A Sub-Analysis Of The Drugnet Survey, Jennifer Reneau

Masters Theses & Specialist Projects

Issues related to substance use/abuse and mental health are significant public health concerns. Substance abuse is considered an individual and community mental health problem. The relationship between substance use and positive mental well-being, however, is less well understood. The purpose of this study was to describe the mental well-being of a sample of occasional, recreational drug users. Drugnet was an on-line survey of recreational drug use by non-deviant adults via the WWW. Volunteer subjects completed the survey over the internet between March and September 1997. Mental health was assessed utilizing the General Well-being Schedule (GWBS). A complete demographic profile of …

Biología Silvopastoril, Steven H. Sharrow

Agroforestry Notes (USDA-NAC)

La producción forestal y la ganadería son dos usos de tierras comunes en muchos lugares del mundo que no tienen riego. El pastoreo forestal es una práctica tradicional en la mayor parte de América del Norte. Aproximadamente 25% del total de las tierras de los EE. UU., son pastoreadas. Los bosques jovenes y los bosques maduros con una copa o dosel poco denso, pueden proveer una cantidad considerable de forraje al ganado. Un itinerario de pastoreo hará más beneficioso el uso de la vegetación que crece bajo la copa de los árboles. De no ser así la vegetación competirá con …

The Biology Of Silvopastoralism, Steven H. Sharrow

Agroforestry Notes (USDA-NAC)

Forestry and livestock grazing are common competing uses for non-irrigated lands around the world. Forest grazing is a traditional practice in most of North America. Approximately 25 percent of all US forest land is grazed by livestock. Young forests and mature open-canopied forests can provide considerable amounts of forage for livestock. Prescription grazing makes beneficial use of ground vegetation that would otherwise compete with trees for soil moisture and nutrients, harbor gnawing rodents, and pose a fire hazard. Pasture grasses and legumes are sometimes seeded into newly harvested forest areas to reduce erosion, to provide high-quality food for deer and …

Ua3/9/2 Wku Institutional Review, James L. Fisher, Ltd.

WKU Administration Documents

Institutional review conducted during Barbara Burch's interim presidency of WKU and presidential search.

Western Kentucky is a good university essentially trapped in time and therefore unable to change significantly. Until these constraints are eliminated or modified, the University will not be able to effectively address major issues of focus, enrollment, organization, personnel, curriculum, governance, athletics, planning and increased public and private support. Rather, it will continue to drift with occasional peripheral and cosmetic changes, none of which will be sufficient to successfully relate to Kentucky's new plan for post-secondary education.

The problems that prevent significant institutional transformation are several, but …

Egg Removal By Brown-Headed Cowbirds: A Field Test Of The Host Incubation Efficiency Hypothesis, Douglas R. Wood, Eric K. Bollinger

Faculty Research & Creative Activity

Brown-headed Cowbirds (Molothrus ater) often remove host eggs, usually to the detriment of the host's reproductive success. We tested the hypothesis that host egg size and number influence the incubation efficiency of a parasitic egg. A single House Sparrow (Passer domesticus) or Brown-headed Cowbird egg was placed in each host nest (addition), and in some nests a host egg was removed as well (addition/removal). Hatching success and incubation length were measured to determine whether host-egg removal conferred an advantage in incubation efficiency compared to simple addition of a parasitic egg. Redwinged Blackbirds (Agelaius phoeniceus) and Chipping Sparrows (Spizella passerina) served …

Meaningful Measures Of The Current Account, Eric O'N. Fisher, Youngsoo Woo

Economics

Since the conventional current account uses cash-flow accounting, it is potentially devoid of economic meaning. Assessing foreign assets at market values and including expected transfers from abroad, this paper reports two measures of the external surplus that are grounded in economic theory. The first measure is the aggregate generational current account, annual differences in the sum of net foreign assets across all current and future generations. The second measure is the generational profile of net foreign assets in a benchmark year. These ideas are implemented with data from Korea.

Tree Root Response To Circling Root Barriers, Laurence R. Costello, Clyde L. Elmore, Scott J. Steinmaus

Biological Sciences

Root system size and distribution were measured for Raywood ash (Fraxinus oxycarpa 'Raywood') and Lombardy poplar (Populus nigra 'Italica') planted with and without circling root barriers. Trees with circling barriers had fewer numbers of roots than controls (no barriers), but mean root diameters were similar. Root depth 30 cm outside barriers was greater for trees with barriers, but at 90 and 150 cm away, depth was equivalent to controls. Roots tended to grow toward the soil surface after growing under the barriers. No consistent differences in root response to any of the four types of barriers tested were …
