    Notizen: Information systems (IS) researchers are now calling for the need to draw from the empirically rich field of organizational innovation. As the impact of strategic systems is increasingly being felt by organizations, the view that these systems are innovations or innovative uses of technology is becoming prevalent. Customer based interorganizational systems (CIOS) represent one of the most prominent types of such systems. This research investigates CIOS adoption. A model is constructed based on significant studies in innovation to identify factors facilitating the adoption decision of a CIOS. Data are gathered from 226 senior executives. Discriminant analysis is used to identify factors that distinguish adopters from nonadopters. Factor analysis of significant variables yielded a parsimonious model of CIOS adoption. The five factor model includes (1) a proactive technological orientation and (2) an internal push for the system as the two most significant sets of facilitators. Implications for research and practice are then discussed.

    Strategic Manufacturing Planning Systems and Their Linkage to Planning System Success (2002)
    Oxford, UK : Blackwell Publishing Ltd
    Decision sciences 33 (2002), S. 0

    Notizen: Academics and practitioners alike are focusing more attention on manufacturing strategy after having recognized the important role it plays in shaping the success of industrial firms. Even though research in this area has increased in the last decade, the focus of much of that work has been on the content rather than the process of the manufacturing strategy. Consequently, this study attempts to understand the important elements of the strategic manufacturing planning process and its effectiveness. Borrowing from the extant literature in the fields of strategic management and information systems, we propose a research model that relates strategic manufacturing planning system design to planning system success. Using structured questionnaires, empirical data is collected from over 200 manufacturing executives to test the model hypotheses. Planning process in manufacturing was found to be a bottom-up approach from a corporate or business perspective, which differs from the top-down planning process prevalent in strategic information systems planning process. Findings also indicate that greater planning system success in manufacturing is associated with a planning system that combines some “rational” elements (formality, comprehensiveness, control focus, longer horizon) with others that lend adaptability (wider participation and more intense interaction). But the strategic manufacturing planning system is more than just a collection of independent planning characteristics. Instead, it can be viewed as a gestalt planning system whereby planning characteristics move together in affecting overall planning system success.

    Important Strategic and Tactical Manufacturing Issues in the 1990s (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Decision sciences 25 (1994), S. 0

    Notizen: This paper reports the identification and ranking of major manufacturing issues that American manufacturing managers and academics must focus on and resolve in the 1990s to be competitive on a global basis. Vice-presidents of manufacturing from over 75 companies across the United States were asked in a Delphi study to rank the key strategic and tactical issues facing American manufacturing in the next three to five years. Based on three rounds of a Delphi study, quality management, manufacturing strategy, and process technology emerged as the top ranked strategic issues. The top ranked tactical issues were quality control, manufacturing planning and control systems, and work force supervision. These issues were valid across diverse industry groups, since the industrial and educational background of the respondents was shown to have no impact on the final consensus rankings and opinions reported in this paper. Factor analysis of the responses by the panel revealed that certain issues tend to be consistently viewed together, and were interpreted accordingly to provide insights into the ranking of issues. Apart from building a consensus among experts on key manufacturing issues of present and future importance, this study can also be helpful for setting future academic research and pedagogical priorities for the field of production and operations management.

    Notizen: Studies were conducled to cstmiate the adsorption parameter k and the bioactivity (in terms of G R50) of di-allate [S-2,3-dichloroallyl N, N-di-isopropyl (thiocar bamate)], iri-allate [S-2,3,3-trichloroallyl N, N -di-isopropyl (thiocar bamate], and [trifiuralin (2,6-dinitro N, N-dlpropyl-4-trifluoromelhylaniline) in a number of Saskatchewan soil. The k values ratiged from 5 for di-allate adsorption m Asquilh loamy sand to 315 for trifluralin adsorption on Melfort loam and were closely related to the soil organic matter content. The relative degree of adsorption was irifluralin 〉 tri-allate 〉di-allaie. For each herbicide, the G R50 values were positively correlated wich organic matter conienl atid wilh k. It was suggested that these nonionic herbicides may be amenable to a predictive approach for field application rates in different soils. Among herbicides for any one soil, however, there was not the same relationship between G R50andk. since the G R50 was least for trifluralin and there was no significant difference between di-allate and tri-allate.

    High frequency regeneration of plantlets from the leaf-bases via somatic embryogenesis and comparison of polypeptide profiles from morphogenic and non-morphogenic calli in wheat (Triticum aestivum) (1991)
    Oxford, UK : Blackwell Publishing Ltd

    Thema: Biologie
    Notizen: High frequency regeneration via somatic embryogenesis was achieved in the leaf-base cultures of wheat (Triticum aestivum L. cv Sonalika) by optimizing the concentration of the hormone, 2,4-dichlorophenoxy acetic acid, and selecting for the appropriate part of the leaf base as explant. It was possible to distinguish compact (morphogenic) and friable (non-morphogenic) calli by the naked eye, after about 60 days of culture on medium enriched with 2,4-dichlorophenoxy acetic acid. The fact that the compact calli are morphogenic, while the friable ones are not, was evident from the observation that only the former formed plantlets after transfer to the basal medium. The morphogenic and non-morphogenic cultures showed substantial difference in soluble protein content on a fresh weight basis. A comparison of silver-stained profiles of soluble polypeptides from morphogenic and non-morphogenic calli revealed many polypeptides specifically associated with either type of calli.

    Nitrogen Metabolism of the Upper Three Leaf Blades of Wheat at Different Soil Nitrogen Levels (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 42 (1978), S. 0 
    Details
    ISSN: 1399-3054
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Some aspects of nitrogen metabolism, during grain development, of the upper three leaf blades on the mainshoot of wheat (Triticum aestivum L.) cv. Pusa Lerma, grown under three soil nitrogen levels (0, 30 and 120 kg ha-1), were investigated. It was observed that these leaf blades were active in NO-3 assimilation. Of the leaf blades, the flag lead blade had significantly higher nitrate reductase activity, higher amount of free amino acid and soluble protein content, whereas the content of NO-3 was significantly lower than in the other two leaf blades. Application of soil nitrogen significantly enhanced the nitrate reductase activity (N30 over N0 and N120 over N30), free amino acid (N30 over N0 and N120 over N30), soluble protein (N120 over N0) and NO-3 content (N30 and N120 over N0) in all three leaf blades. During the 35-day period, viz. from 7 days prior to anthesis to 28 days after anthesis, the three leaf blades together reduced 280, 608 and 1397 NO-3μmol under N0, N30 and N120, respectively.

    Nitrogen Metabolism of the Upper Three Leaf Blades of Wheat at Different Soil Nitrogen Levels (1978)

    Thema: Biologie
    Notizen: Upper three leaf blades on the mainshoot of wheat cultivar, cv. Pusa Lerma, grown under three soil nitrogen levels (0, 30 and 120 kg ha-1), were examined for changes in total reduced nitrogen and protease activity at pH 4.0 and 7.0. No net loss of reduced nitrogen takes place prior to and around anthesis. The protease activity is low during this period. At later stages there is rise in the loss of nitrogen which is paralleled by enhancement in protease activity. From amongst the leaf blades, nitrogen concentration is significantly high in the flag and penultimate as compared to the values in the third leaf blade. There were significant differences in protease activity (pH 4.0) amongst the leaf blades. At pH 7.0, however, the differences between the flag and penultimate leaf blades were not significant. Highest enzyme activity was in the flag followed by penultimate and then third leaf blade. Soil N application significantly enhanced the nitrogen content of all the leaf blades. At pH 4.0, the protease activity (g fr. wt.-1) increased significantly due to soil N application (N30 over N0). There was, however, decline in the enzyme activity at pH 7.0, though the differences at different soil N levels were not significant. Analysis in terms of μmol N (reduced form) accumulated in the grains (ear)-1 revealed that two-thirds of N is translocated by 28-day stage and the rest between 28-day and final harvest. The three leaf blades together contributed 22.7, 32.6 and 48.5% of the grain N (ear)-1 at N0, N30 and N120- respectively. Most of the nitrogen applied to the soil is reduced by these leaf blades.
