Investigating the Role of Information Technology in Building Buyer-Supplier Relationships

A widely held position observed through the lens of transaction cost theory (TCT) has been the role of information technology in decreasing transaction costs between buyers and suppliers and in creating more market based governance structures. However, observations have not supported this contention. In particular, buyer-supplier dyads often engage in cooperative behavior that could offset opportunistic tendencies espoused by TCT. The role of IT in this structure is unclear. This paper examines the relationship between perceived transaction costs and the concept of relationalism within buyer-supplier dyads. The role of IT in mediating this relationship is also examined. Survey data from 203 buyers in the OEM electronics industry is used to test proposed hypotheses. All major constructs, transaction costs, relationalism, and IT use are operationalized using validated multidimensional scales. The results suggest a positive role of IT in partially offsetting the negative relationship between transaction costs and relationalism. The results suggest that the decision to use IT within the dyad can encourage a commitment to establishing relational behavior

Technology Architecture: Examining a Data Driven Model

The 1990s has been marked by the widespread transfer of new information technologies that can alter the fundamental nature of computing. Effective storage and multitasking processing technologies have combined with developments in telecommunications to create new opportunities for resource sharing and communication among computers. The importance of this revolution has been recognized by senior information systems executives, whom have identified the planning and development of corporate information technology structure (architecture) as the most critical issue of the decade (Niederman , Brancheau & Wetherbe, 91). This study, through the responses of 313 North American senior IS executives, will explore the nature of IT (information technology) structure and its relationship to organizational structure

Properties of Sequential Chromospheric Brightenings and Associated Flare Ribbons

We report on the physical properties of solar sequential chromospheric brightenings (SCBs) observed in conjunction with moderate-sized chromospheric flares with associated CMEs. To characterize these ephemeral events, we developed automated procedures to identify and track subsections (kernels) of solar flares and associated SCBs using high resolution H-alpha images. Following the algorithmic identification and a statistical analysis, we compare and find the following: SCBs are distinctly different from flare kernels in their temporal characteristics of intensity, Doppler structure, duration, and location properties. We demonstrate that flare ribbons are themselves made up of subsections exhibiting differing characteristics. Flare kernels are measured to have a mean propagation speed of 0.2 km/s and a maximum speed of 2.3 km/s over a mean distance of 5 x 10^3 km. Within the studied population of SCBs, different classes of characteristics are observed with coincident negative, positive, or both negative and positive Doppler shifts of a few km/s. The appearance of SCBs precede peak flare intensity by ~12 minutes and decay ~1 hour later. They are also found to propagate laterally away from flare center in clusters at 41 km/s or 89 km/s. Given SCBs distinctive nature compared to flares, we suggest a different physical mechanism relating to their origin than the associated flare. We present a heuristic model of the origin of SCBs.Comment: 24 pages, 17 figure

The Large and Small Scale Structures of Dust in the Star-Forming Perseus Molecular Cloud

We present an analysis of ~3.5 square degrees of submillimetre continuum and extinction data of the Perseus molecular cloud. We identify 58 clumps in the submillimetre map and we identify 39 structures (`cores') and 11 associations of structures (`super cores') in the extinction map. The cumulative mass distributions of the submillimetre clumps and extinction cores have steep slopes (alpha ~ 2 and 1.5 - 2 respectively), steeper than the Salpeter IMF (alpha = 1.35), while the distribution of extinction super cores has a shallow slope (alpha ~ 1). Most of the submillimetre clumps are well fit by stable Bonnor-Ebert spheres with 10K < T < 19K and 5.5 < log_10(P_ext/k) < 6.0. The clumps are found only in the highest column density regions (A_V > 5 - 7 mag), although Bonnor-Ebert models suggest that we should have been able to detect them at lower column densities if they exist. These observations provide a stronger case for an extinction threshold than that found in analysis of less sensitive observations of the Ophiuchus molecular cloud. The relationship between submillimetre clumps and their parent extinction core has been analyzed. The submillimetre clumps tend to lie offset from the larger extinction peaks, suggesting the clumps formed via an external triggering event, consistent with previous observations.Comment: 38 pages, 12 figures, accepted by Astrophysical Journal slight changes to original due to a slight 3" error in the coordinates of the SCUBA ma

Integrating Water Resources and Land Use Planning

Information and recommendations were developed pertaining to the integrating of water resource and land use planning at a conceptual level. In the accomplishment of this goal, the report acts as a vehicle of information transfer to facilitate recognition of the interrelationships between land use and winter resources planning by practitioners in both areas. The approach that was used includes six basic components: 1) the clarification of current planning theory as it pertains to both water and land use planning, 2) analysis and review of historical and current land use planning practices, 3) review of historical and current land use planning practices, 4) identification of problems and concepts which would affect the integration of land and water planning, 5) the design of a conceptual framework (the IRUM model) which would facilitate the integration of land and water planning, and 6) a case study of a selected planning region for small scale applications of the IRUM model. In connection with the case study, a general population survey was taken to identify social and environmental values, land and water use preferences, and other conditions which would affect an integrated planning effort. The recommendations developed in the report cover institutional issues such as culture, law, and organizational arrangements, and also methodological issues such as conceptual framework development and procedural problems which will confront actual efforts to integrate land and water resource planning
