    Additive Effects on Si3N4 Oxidation/Volatilization in Water Vapor (2003)
    Westerville, Ohio : American Ceramics Society
    Journal of the American Ceramic Society 86 (2003), S. 0 
    Details

    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Maschinenbau , Physik
    Notizen: Two commercially available additive-containing silicon nitride materials were exposed in four environments which ranged in severity from dry oxygen at 1 atm pressure, and low gas velocity, to an actual turbine engine. Oxidation and volatilization kinetics were monitored at temperatures ranging from 1066° to 1400°C. The main purpose of this paper is to examine the surface oxide morphology resulting from the exposures. It was found that the material surface was enriched in rare-earth silicate phases in combustion environments when compared with the oxides formed on materials exposed in dry oxygen. However, the in situ formation of rare-earth disilicate phases offered little additional protection from the volatilization of silica observed in combustion environments. It was concluded that externally applied environmental barrier coatings are needed to protect additive-containing silicon nitride materials from volatilization reactions in combustion environments.

    Notizen: Employees (N = 92) from the USA and Mexico completed questionnaires that measured rule–breaking, drug use, and attitudes toward theft. Integrity–related variable clusters had significant intercorrelations. Rule–breaking correlated with supervisor evaluations of work performance in Spanish and with trustworthiness in English.

    EVALUATION OF Ann AGNPS NITROGEN LOADING IN AN AGRICULTURAL WATERSHED (2003)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 39 (2003), S. 0 
    Details

    Notizen: : Pollutants entering a water system can be very destructive to the health of that system. Best Management Practices (BMPs) are used to reduce these pollutants, but understanding the most effective practices is very difficult. Watershed models are an effective tool to aid in the decision-making process of selecting the BMPs that are most effective in reducing the pollutant loading and are also the most cost effective. The Annualized Agricultural Nonpoint Source Pollution model (AnnAGNPS 2.0) is a technological tool that can be used to estimate watershed response to agricultural management practices. The main purpose of this paper is to test the performance of AnnAGNPS 2.0 on nitrogen loading using comparisons with measurements from the Deep Hollow watershed of the Mississippi Delta Management Systems Evaluation Area (MDMSEA) project. Previous work has demonstrated the capability of the model to simulate runoff and sediment. From sensitivity analyses in this study, initial nitrogen concentration in the soil and crop nitrogen uptake had the most impact on the nitrogen loadings. AnnAGNPS simulations of monthly nitrogen loadings are poor. However, statistical test (t-test) showed that the predicted nitrogen loading is not significantly different from observed nitrogen loading at the 95 percent level of confidence.

    A Test of Alternative Measures of Disconfirmation (2003)
    350 Main Street , Malden , MA 02148 , USA , and 9600 Garsington Road , Oxford OX4 2DQ , UK . : Blackwell Publishing

    Notizen: Disconfirmation has been widely used in a number of research traditions, however there are many different operationalizations of this construct. Little research has investigated the relative effectiveness of these various methods. The research reported here examines five operationalizations of disconfirmation and their effect on satisfaction. These tests are carried out using two different comparison standards in two different settings. The results indicate some methods are better in certain situations and are inappropriate in others. Implications for both practical and theoretical research are discussed.

    The case against Microsoft: An ethical perspective (2003)
    Oxford, UK and Boston, USA : Blackwell Publishing Ltd
    Business ethics 12 (2003), S. 0

    Notizen: This paper discusses the complex Microsoft anti-trust trial and the company 's questionable behavior during the browser wars with Netscape.It reviews the essentials of the legal case against Microsoft along with the company 's efforts to refute the charges against it, including the presumption of monopoly power. After laying the groundwork by providing conceptual background on the notion of fair competition, the paper turns to an ethical analysis of Microsoft 's conduct. We conclude that Microsoft 's behavior was excessively opportunistic during the browser wars.The company did not compete constructively or positively, but instead sought to undermine the competitive process.It also developed biased software code that tilted the playing ?eld in its direction.These actions caused harm to the company 's stakeholders by obstructing consumer choice and impeding innovation.

    Genetic population structure and neighbourhood population size estimates of the caddisfly Plectrocnemia conspersa (2003)
    Oxford, UK : Blackwell Science Ltd
    Freshwater biology 48 (2003), S. 0 
    Details
    ISSN: 1365-2427
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: 1. We used both genetic and ecological methods to evaluate the role of history and the scale of colonisation in structuring populations of the caddisfly Plectrocnemia conspersa. There was no genetic differentiation between sites up to 20 km apart, despite population sizes suggesting that genetic drift could create substantial variation at this scale.2. Genetic differentiation between populations separated by more than 20 km was greater than expected given the contrasting short-range trend, and implied a neighbourhood population size that is implausibly small. Therefore, the evolutionary processes that affect the short-range trend do not explain differentiation over greater distances.3. At small scales (〈20 km), relatively short flights by winged adults spread over a number of generations could account for the spread of genes. For instance, dispersing individuals could found small (often temporary) populations, which may then grow and exchange genes with larger and more permanent local populations, amplifying the effects of the initial gene flow.4. Over larger scales (20–500 km), substantial gaps between regions containing suitable habitat patches could reduce the number of colonisation events. Genetic patterns at this scale may date from the time they were last colonised. Previous ecological studies have rarely examined the dynamics of aquatic insect populations over these larger geographical scales, yet these processes may be central to their persistence and spread.

    Peering at the Past Century's Corporate Strategy Through the Looking Glass of Time-Series Analysis: Extrapolating from Chandler's Classic Mid-Century American Firms? (2003)
    Oxford, UK : Blackwell Publishing Ltd.
    Journal of management studies 40 (2003), S. 0

    ISSN: 1467-6486
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Wirtschaftswissenschaften
    Notizen: This study has a dual thrust. Substantively, it revisits Chandler's pragmatic fit-performance directive (Chandler's ‘efficiency thesis’) or his assertion that firms whose structure matches their strategy become more effective than mismatched firms. It is important to revisit the empirical origin of this result in view of its gradual international extrapolation beyond the time and place in which it originated. By gathering the financial data relevant to the firms cited as examples by Chandler, we identify whether the change to the multidivisional structure did indeed lead to improved financial performance in the mid-twentieth century American firms he described. Methodologically, it explores a novel approach to the empirical validation of basic theories. Using historical replication, it undertakes a longitudinal, time-series analysis of a classic theory based on twentieth-century data, and thus investigates the testing of classic data with a modern tool. We undertake multiple replications. Three separate longitudinal studies are performed, consisting of two forecasting methods applied to 11 individual time series, and a comparison technique applied to the same. These are used with the three most common measures of performance at the time of Chandler's writing. All three methods reveal that the differences predicted by his theory are not borne out by the longitudinal analysis of a core group of Chandler's own exemplary firms. The three sets of longitudinal analyses we present raise some substantive questions regarding this cornerstone of classical theory, and carry positive methodological portents regarding the use of historical replication as a stepping-stone for twenty-first-century research.
