- Description:
- In the report many methodological and technological approaches for creating Decision Support Systems for regional and federal authorities are presented. They are based on using new information technologies such as Data Warehousing, On-Line Analytical Processing, simulation modeling and others. The general structure of model complex for region social-economic development and its realization based on methods of system dynamics and modern technologies of simulation modeling are described.

- Description:
- Many green practices are widely understood and known to bring benefits beyond reduced energy use. Yet, organizations often fail to implement them. What explains these failures? Past theory suggests that adoption and implementation will be most likely to fail when practices are difficult to recognize given current competencies or organizational structures, require complex knowledge, or when the organization faces short term pressures that force it to abandon implementation early. Here, we present a case study of an organization that fails to adopt an important best practice despite the fact that the benefits and steps toward implementation are well understood and external short term pressures are minimal. We find that instead, short term pressures are created entirely internally by the structure of relations across organizational boundaries, causing individuals to misperceive the best practice as a cost that can be put off rather than an investment with positive future returns. Thus, even the simplest of innovations and improvements can be stymied by dynamics internal to an organization.

- Description:
- Governments around the world have developed e-government programs hoping to obtain important benefits. However, many e-government projects fail to deliver their promises. Some of such failures are the result of a lack of understanding about the relationships among technologies, information use, organizational factors, institutional arrangements, and socio-economic contexts involved in the selection, implementation, and use of information and communication technologies (ICT), producing mismatches and unintended consequences. The paper proposes the use of institutional theory and dynamic simulation, particularly System Dynamics, as an integrated and comprehensive approach to understand e-government phenomena. The paper draws on the case of the e-Mexico program, particularly in the strategy to create web-based content to the citizen in the areas of education, health, economy and government. Using the same technological infrastructure and under the leadership of the same Federal Ministry, four different networks of government and non-government organizations engaged in the creation of Internet portals to create relevant content in these areas. Differences in institutional arrangements and organizational factors resulted on different technology enactments.

- Description:
- This paper presents a preliminary System Dynamics model developed to analyze sustainability of a natural reserve in Mexico: the Tamiahua wetlands. Wetlands are often referred to as natureâs kidney because they filter contaminants from water. In spite of their importance, wetlands are endangered areas around the world. The preliminary model presented in this paper suggests that fishing activity in the Tamiahua wetlands, together with contaminants from human activity, have the potential to damage the diversity of species in the ecosystem, endangering the sustainability of the system. Continued work on the model is intended to explore appropriate ways of preserving Tamiahua, providing inhabitants with economic activities that promote the sustainability of the region.

- Description:
- It is hard to study problems where boundedly rational stakeholders determine important decisions in the system. This is because the dynamics of boundedly rational social cognition and social influence are complex and because data about stakeholder mental models and social networks are difficult to elicit, organize, and test. The proposed method to study these kinds of problems combines data elicitation techniques from stakeholder management, theories of boundedly rational social cognition and social influence, and a system dynamics simulation model. This method takes rough qualitative stakeholder data, organizes it into stakeholder diagrams, and uses it to parametrically populate existing system dynamics structure. This allows the researcher to quantitatively simulate complex stakeholder-centric problems where data quality is poor.

- Description:
- At its genesis, system dynamics (SD) modeling was developed to examine the temporal behavior of interrelated systems. This ability has made SD modeling and analysis the choice for decision and policy makers to do scenario testing and risk analysis. In addition to the conceptual advantages of SD modeling in this realm, are the many SD modeling platforms that have been developed that greatly simplify model creation and more importantly, provide an environment for visualizing the output. However, when making decisions that involve urban planning, electrical and/or water infrastructure, and the like, or for examining impacts of resource development on the environment, the spatial aspects of the decision becomes just as important as the temporal dynamics. To properly support these decisions, simultaneous visualization of the temporal and spatial dynamics is needed. This paper presents a methodology for utilizing vbscript from within the SD development platform Powersim to dynamically link Powersim simulations with Google Earth to visualize, in real time, spatial data that change over time. The presentation will describe the logic behind the approach, its capabilities and limitations, and areas for improvement that should be addressed.

- Description:
- Becker (1968) posits the notion that criminals respond, like any other rational agent, to the benefits and costs of their activities. From this notion follows the deterrence hypothesis, the idea that judicial policies can help reduce crime through an increase in the expected costs of illegal activities. Yet, despite implementing the suggestions implied by such models, more and more countries undergo a large escalation of criminal activities. We explore this issue using a longitudinal data set of relevant judicial figures for one country. The data are used to calibrate a System Dynamics model. We find that, contrary to what would be ordinarily expected, criminals tend to be punished not exclusively on the basis of their behavior, but in terms of other institutional variables. Our data show that judges and prosecutors are prone to dismiss cases when the backlog to be processed exceeds a threshold, in a manner that much corresponds to the archetype "Shifting the Burden To." The effect of judgesâ decision rules which results in potential criminals who are acquitted without apparent reason is that of creating incentives for criminals and others to engage in criminal activities, thus causing crime rates, and the backlog of cases, to increase even further.
