Communication and equilibrium in discontinuous games of incomplete information

This paper offers a new approach to the study of economic problems usually modeled as games of incomplete information with discontinuous payoffs. Typically, the discontinuities arise from indeterminacies (ties) in the underlying problem. The point of view taken here is that the tie-breaking rules that resolve these indeterminacies should be viewed as part of the solution rather than part of the description of the model. A solution is therefore a tie-breaking rule together with strategies satisfying the usual best-response criterion. When information is incomplete, solutions need not exist; that is, there may be no tie-breaking rule that is compatible with the existence of strategy profiles satisfying the usual best-response criteria. It is shown that the introduction of incentive compatible communication (cheap talk) restores existence

Extent of use of orthodox and traditional treatments and preventive measures against malaria among rural dwellers in Abia State

The study assessed the extent of use of the orthodox and traditional treatment preventive measures against malaria among rural dwellers in Abia State. Primary data were collected using structured questionnaire from 180 respondents via multi- stage procedure. Data were subjected to descriptive statistics analysis. About 78% and 95.6% of the respondents were married and literates respectively. A mean age of 46 years, a mean monthly income of about ₦24,227.78 and a mean household size of about 5 persons respectively were recorded by the respondents. The result further revealed that the respondents employed different types of malaria treatment practices (100% of the respondents employed orthodox practices and 11.78% employed traditional practices).The extent of adoption of malaria preventive measures was low ( X= 2.2) and only about 45.4% of the respondents had a good knowledge level in the use of orthodox malaria treatment practices . The result equally revealed low (X= 1.78) attitudinal level by the respondents towards the use of orthodox malaria treatment practices. It equally, revealed a low (X= 1.98) practice level and gave the Relative Credibility Index (RCI) of the respondents over the use of traditional methods of controlling malaria as (RCI = 2.9). The study concludes that the respondents in the study area had a low Knowledge, Attitude and Practice (KAP) level over the use of orthodox malaria treatment practices. Therefore, the study recommends more awareness campaign by the health workers mostly in the rural areas in order to increase the KAP level of the rural dwellers in the use of orthodox malaria treatment practices as this will enormously reduce the devastating effects of malaria sickness in Nigeria and mostly in the study area,Keywords: Malaria Treatments, Orthodox, Traditional and Abia Stat

Dirac Equation Studies in the Tunnelling Energy Zone

We investigate the tunnelling zone V0 < E < V0+m for a one-dimensional potential within the Dirac equation. We find the appearance of superluminal transit times akin to the Hartman effect.Comment: 12 pages, 4 figure

Potential Scattering in Dirac Field Theory

We develop the potential scattering of a spinor within the context of perturbation field theory. As an application, we reproduce, up to second order in the potential, the diffusion results for a potential barrier of quantum mechanics. An immediate consequence is a simple generalization to arbitrary potential forms, a feature not possible in quantum mechanics.Comment: 7 page
