In this paper we identify topics and insights drawn from the behavioral sciences that can be used to provide the initial underpinnings of the psychological side of service science. We also propose an agenda for research and education in the area.

All herbicides except atrazine effectively controlled perennial grasses, Cacodylic acid was the most effective contact chemical, with dosage levels of 7 and 10 kg/ha achieving 77 percent control of the grasses after two applications, Four and 6 kg/ha of amitrole...

As the research moves forward, individual groups have begun to develop unique methods of propulsion, each having distinctive engineering trade-offs: weight is sacrificed for power; speed is forfeited for control accuracy, etc. Early spherical robots operated similar to a hamster ball and had a limited torque and a high-energy loss due to internal friction. Researchers have begun to develop various novel concepts to maneuver and control this family of robot. This article is an overview of the current research directions that various groups have taken, the nomenclature used in this subdiscipline, and the various uses of the fundamental principles of physics for propelling a spherical robot.

The goal of such studies is to develop an understanding of what works and.what does not work in manufacturing, what are best practices, and as the name implies, benchmarking one’s own company and industry against others as a starting point for improving operational performance. One would expect that similar benefits would accrue to financial services, yet there are few systematic benchmarking studies reported in the literature. (An exception being the series of benchmarking studies of world class strategies and performance in retail banking conducted by researchers at University of North Carolina under the aegis of the Bank Administration Institute from 1987 to 1993 (Roth and Van der Velde, 1991 Roth and Van der Velde, 1992; Roth, 1993;Roth and Jackson, 1995).)

This paper summarizes the results of an Environmental Research Consortium program, carried out under the auspices of the U.S. Council for Automotive Research. The program focused on particulate matter (PM) emissions from representative, current-technology, light-duty gasoline vehicles produced by DaimlerChrysler Corp., Ford Motor Co., and General Motors Corp. The vehicles, for the most part taken from the manufacturer's certification and durability fleets, were dynamometer-tested using the three-phase Federal Test Procedure in the companies' laboratories. The test fleet was made up of a mixture of both lowmileage (2K-35K miles) and high-mileage (60K-150K miles) cars, vans, sport utility vehicles, and light trucks. For each vehicle tested, PM emissions were accumulated over 4 coldstart tests, which were run on successive days. PM emission rates from the entire fleet (22 vehicles total) averaged less than 2 mg/mile. All 18 vehicles tested using California Phase 2 reformulated gasoline had PM emission rates less than 2 mg/ mile at both low and high mileages. IMPLICATIONS Motor vehicles are a source of PM. The significance of vehicles as contributors to urban environmental particle concentrations needs to be evaluated from both environmental and vehicle measurement data. This report provides particle emissions data for current-technology (1994-1998) gasoline vehicles at both low and high mileages. Particle emission rates for both low-and highmileage vehicles, using California reformulated fuel, are about 2 mg/mile.

The findings reported are based on a sample of firms from the international service study (ISS) from four service sectors: financial services, professional services, hotels, and utilities. The paper argues that generally there are differences in services management practices and performance and, more specifically, that service quality performance may be explained by the nature and market dynamics of the service sector within the individual countries.

Seismic reflection profiles show, however, the northern and southern parts to be very different. The northern sections is a deep basin filled with thick uniformly stratified sediments. It is enclosed by the continental margin to the west and north, Chain ridge to the east, and shallow basement structure to the south. A change in depth of basement occurs along an approximately eastr-west line at latitude 3°30'N very near the southern end of Chain ridge. In the southern portion of the basin the basement is shallow, and, immediately south of latitude 3°30'N, it has high relief. Stratified flat.-lying sediments fill the basement depressions, and isolated hills formed of basement material rise above the abyssal plain deposits. Farther to the south the abyssal plain becomes very narrow. Gabbro dredged from the southeast slope of Chain ridge bas been dated by the potassium-argon method as 89.6 ± 4.5 m.y., which should be considered a minimum age. The evidence suggests that the entire sediment sequence of the northern basin was deposited subsequent to the formation of the ridge. The thin sediment cover of the southern portion of the basin is probably no older than Tertiary.

The model incorporates both environmental and human factors, including vegetation, temperature, precipitation, human structures, and transportation. Spatial autocorrelation was examined for both fire activity and vegetation to determine the specification of neighborhood effects in the model. Parameters were estimated using stepwise logistic regressions. Among the explanatory variables, the variable that represents the neighborhood effects of spatial processes is shown to be of great importance in the distribution of wildland fires. An important implication of this result is that the management of wildland fires must take into consideration neighborhood effects in addition to environmental and human factors. The distribution of fire occurrence probability is more accurately mapped when the model incorporates the spatial term of neighborhood effects. The map of fire occurrence probability is useful for designing large-scale management strategies of wildfire prevention,

Purpose: This exploratory study aims to understand the prevalence of secondhand smoke exposure; assess levels of awareness of the dangers of secondhand smoke; and identify strategies for building increased awareness of these issues in African immigrant communities in Minnesota. Methods: Key informant interviews with ten African women community leaders, focus groups with 29 female African youth, and surveys of 223 African women were conducted between August 2008 and March 2009. The focus groups and key informant interviews were in English, and the surveys were in English, French, Oromo, and Somali. Results: Over one quarter of African women reported daily exposure to cigarette smoke, and one in ten women reported daily exposure to smoke from shisha (fruit-flavored tobacco smoked in a hookah or waterpipe). Many respondents had general awareness of the health impacts of tobacco smoke, but some were unsure. The majority felt that increased awareness was badly needed in their communities. Awareness of the health impacts of shisha smoking was particularly low. Strategies for increasing awareness include: using media and visual images, attending large gatherings, and appealing to community members' priorities, including protecting their children. Conclusions: Exposure to secondhand smoke among women and children in African immigrant communities in Minnesota is substantial. Awareness about the health impacts of secondhand smoke exposure in these communities needs to be increased. Disseminating visual information at existing community gatherings or appealing to individual priorities may be the best approaches to increase awareness and motivate change.

Here, it is the service industries in the UK and the US which come under the microscope. Among the companies surveyed, there were more world-class performers in the US than the UK, but also more low performers. The concluding part of the article is diagnostic - the authors also suggest measures which could improve performance.
