[reaction: see text]. Yttrium-salen complexes effect transacylation between enolesters and chiral secondary alcohols, resulting in varying degrees of kinetic resolution. Even though the enantioselectivity remains modest (k(fast)/k(slow) up to 4.81), these results represent the first demonstration of a conceptually new metal-catalyzed acyl transfer process that results in kinetic resolution. On ...

Belief function theory provides a flexible way to combine information provided by different sources. This combination is usually followed by a decision making which can be handled by a range of decision rules. Some rules help to choose the most likely hypothesis. Others allow that a decision is made on a set of hypotheses. In [6], we proposed a decision rule based on a distance measure. First, ...

vt(mt;χt) = u(χt(mt)) + β Et[vt+1((mt −χt(mt))R+ yt+1)] (1) vt(mt;χt) = u(χt(mt)) + δβ Et[vt+1((mt −χt(mt))R+ yt+1)] (2) Notice that these functions are well defined for any consumption function χt(mt) that is feasible; they are not Bellman equations because they do not assume that the consumption function χt is optimal. For example, these functions would be well defined for χt(mt) = mt, or for...

Can we tailor fit the training to enhance judgment accuracy by changing to the learning format that invites the most effective cognitive process for the task environment at hand? The results from a study on multiple-cue judgments revealed that observing the cues and the criterion of exemplars simultaneously with no feedback involved in the training, a learning format predicted to invite exempla...

Kojima and Manea (2010) present two characterizations of when an allocation rule corresponds to the agent-proposing deferred acceptance algorithm for some substitutable priority rule of the objects being assigned. Building on their results we characterize when an allocation rule is outcome equivalent to the deferred acceptance algorithm for every substitutable priority rule. In particular, an a...

In this experimental study we analyse three collective and one individual punishment rule in a public good setting. We show that under all punishment rules cooperation is stronger and more sustainable than reported from settings without punishment. Moreover, we present evidence and explanations for differences between the rules concerning punishment intensity, contribution and profit levels, as...

How should one regulate access to a network? The aim of this paper is to consider the optimality of a simple rule, the Efficient Component Pricing Rule (ECPR), under non-linear pricing for intermediate and final goods. The analysis focuses on the interactions between regulation and competition in a second degree price discrimination setting. Rather specific assumptions regarding competition and...

Motivated by applications to crowdsourcing, we study voting rules that output a correct ranking of alternatives by quality from a large collection of noisy input rankings. We seek voting rules that are supremely robust to noise, in the sense of being correct in the face of any “reasonable” type of noise. We show that there is such a voting rule, which we call the modal ranking rule. Moreover, w...

Addition rule: The probability of any of one of several mutually exclusive events occurring is equal to the sum of their individual probabilities. A typical example is the probability of a baby to be homozygous or heterozygous for a Mendelian recessive disorder when both parents are carriers. This equals to 1/4 + 1/2 = 3/4. A baby can be either homozygous or heterozygous but not both of them at...
