Preference reversals have been widely studied using risky or riskless gambles. However, little is known about preference reversals under ambiguity. We asked subjects to make a binary choice between ambiguous P-bets and ambiguous $-bets and elicited their willingness to accept. Subjects then performed the same two tasks with risky bets, where the probability of winning for a given risky bet is t...

effective microorganisms (em) is a commercial biofertilizer mainly consists of photosynthetic and lactic acid bacteria, yeast and actinomycetes. in order to evaluate the influence of em (0 and %1) and salt stress (0 mm, 50 mm, 100 mm and 150 mm) on the morphophysiological characteristics of pomegranate cv. shishe-kap, a factorial experiment was conducted based on the completely randomized desig...

the nutrient requirements and performance guidelines of management guides are based upon many actual flock results obtained under good environmental and management conditions. in practice and under the prevalent poultry industry situation, through these nutrient levels, iranian farmers cannot attain the performance reported in management guidelines. an estimation of the model of broiler breeder...

When the minimization of mean square error (or variance) is a primary criterion for chosing an estimator of means or totals, then second moment estimates are often necessary too. Some examples of this are composite estimators where the component weights are functions of the component variances, generalized least squares estimators where an estimate of a covariance matrix is required, and the no...

a {em 2-rainbow dominating function} (2rdf) of a graph $g$ is a function $f$ from the vertex set $v(g)$ to the set of all subsets of the set ${1,2}$ such that for any vertex $vin v(g)$ with $f(v)=emptyset$ the condition $bigcup_{uin n(v)}f(u)={1,2}$ is fulfilled, where $n(v)$ is the open neighborhood of $v$. the {em weight} of a 2rdf $f$ is the value $omega(f)=sum_{vin v}|f (v)|$. the {em $2$-r...
