Forests and rangelands are the most important natural ecosystems which provide many economic benefits to the society due to their biodiversity and ecological functionalities. Dashtenaz wildlife refuge, Sari, is a sylvan region, covering 55 ha of rangeland with abundant diversity, is refuge of an endangered species of deer called Dama mesopotamica. In this study, Contingent Valuation Method (CVM...

In this study, female preferences and behavioural isolation were estimated in a pair of allopatric sister species, Etheostoma duryi and Etheostoma flavum. Dichotomous mate preference trials were conducted to determine whether females prefer to associate with conspecific over heterospecific males and free-spawning assays were conducted to determine whether those preferences translated into behav...

Determining the health insurance premium is most important aspect in providing social insurance. In measuring rate, it needed to calculate cost of service. One possible methodological tool calculating contingent valuation method for evaluation consumers’ capacity and their willingness pay services. This study applied a Logit model, having binary depended variable with follow up dichotomous choi...

The aim of this paper is to find normative foundations of Approval Voting.In order to show that Approval Voting is the only social choice functionthat satisfies anonymity, neutrality, strategy-proofness and strict mono-tonicity we rely on an intermediate result which relates strategy-proofnessof a social choice function to the properties of Independence of IrrelevantAlte...

In biostatistics and medical research, longitudinal data are often composed of repeated assessments a variable dichotomous indicators to mark an event interest. Consequently, joint modeling time-to-event has generated much interest in these disciplines over the previous decade. In behavioural sciences, too, we interested relating individual trajector...

We consider the problem of allocating a set on indivisible items to players with private preferences in an efficient and fair way. focus valuations that have dichotomous marginals, which added value any item is either 0 or 1, aim design truthful allocation mechanisms (without money) maximize welfare are fair. For case submodular we such deterministic mechanism. The output by our mechanism Loren...

The binary logistic regression model (LRM) is practical in situations when the response variable (RV) dichotomous. maximum likelihood estimator (MLE) generally considered to estimate LRM parameters. However, presence of multicollinearity (MC), MLE not correct choice due its inflated standard deviation (SD) and errors (SE) estimates. To combat MC, commonly used biased estimators, i.e., Ridge est...
