Dictatorial domains

Summary. In this paper, we introduce the notion of a linked domain and prove that a non-manipulable social choice function defined on such a domain must be dictatorial. This result not only generalizes the Gibbard-Satterthwaite Theorem but also demonstrates that the equivalence between dictatorship and non-manipulability is far more robust than suggested by that theorem. We provide an application of this result in a particular model of voting. We also provide a necessary condition for a domain to be dictatorial and use it to characterize dictatorial domains in the cases where the number of alternatives is three.

The Participatory Economy. An Evolutionary Hypothesis and a Strategy for Development

This article proposes a synthetic new concept of logics of action, intending to apply it to the market, the family, and the polity (inclusive of the state and the community) as crucial instances of what may be termed provisioning domains. These are the broadest or most general domains in which economic activities take place. This article defines a logic of action as a set of socially shared rules of thought and behavior (i.e., socially shared mental models and behavioral rules) that involve a domain of action, the metric used, and the objectives or obligations associated with the positions people occupy in this domain. The domain by itself does not suffice to characterize a logic, and it has to be combined with the other two aspects. The article further discusses the relation between logics of action and institutions, arguing that logics of action are institutions with specific characteristics. They are conceived in relation to very broad provisioning domains and, as such, they have a high degree of generality. The market, the family, and the civic logics may be called provisioning institutional logics, but important differences do exist between the proposed concept herein and some treatments of institutional logics.     

Survey Estimates by Calibration on Complex Auxiliary Information

In the last decade, calibration estimation has developed into an important field of research in survey sampling. Calibration is now an important methodological instrument in the production of statistics. Several national statistical agencies have developed software designed to compute calibrated weights based on auxiliary information available in population registers and other sources. This paper reviews some recent progress and offers some new perspectives. Calibration estimation can be used to advantage in a range of different survey conditions. This paper examines several situations, including estimation for domains in one‐phase sampling, estimation for two‐phase sampling, and estimation for two‐stage sampling with integrated weighting. Typical of those situations is complex auxiliary information, a term that we use for information made up of several components. An example occurs when a two‐stage sample survey has information both for units and for clusters of units, or when estimation for domains relies on information from different parts of the population. Complex auxiliary information opens up more than one way of computing the final calibrated weights to be used in estimation. They may be computed in a single step or in two or more successive steps. Depending on the approach, the resulting estimates do differ to some degree. All significant parts of the total information should be reflected in the final weights. The effectiveness of the complex information is mirrored by the variance of the resulting calibration estimator. Its exact variance is not presentable in simple form. Close approximation is possible via the corresponding linearized statistic. We define and use automated linearization as a shortcut in finding the linearized statistic. Its variance is easy to state, to interpret and to estimate. The variance components are expressed in terms of residuals, similar to those of standard regression theory. Visual inspection of the residuals reveals how the different components of the complex auxiliary information interact and work together toward reducing the variance.     

Problems and Issues with the Domain Name System: A Review of Fortune 100 Companies

ABSTRACT

Domain names are a very important component of the Internet. The regulations and standards governing the registration of domain names have evolved over the past decade. Although various laws have been passed to protect businesses and organizations, this paper examines the effectiveness of such actions. A sample of Fortune 100 companies was examined to determine who had ownership of the top-level domain (.com, .net, .org, .biz) associated with their corporate second-level domain (e.g., walmart, intel). A summary and discussion of the findings are presented.     

Implementing global corporate citizenship: An integrated business framework

Recent economic, social-political, and natural disasters have all served to highlight the fragility of the global marketplace. As such, it is no longer questioned as to whether or not companies should be good corporate citizens; that is a given. Rather, concern in the 21^st century centers on how businesses can become better global corporate citizens. Unfortunately, without clear guidance regarding how this may be accomplished, global corporate citizenship will remain a fringe activity and not become a critical component of an organization's core business strategy. The integrated framework presented herein identifies key elements and tips for implementing a business-based approach to global corporate citizenship.
