Eastern Kentucky University’s (EKU’s) Environmental Health Science (EHS) program and the entire EHS profession suffered a great loss on August 9, 2014, when our colleague and my good friend Professor Joe Beck passed away. I have decided to do my column on one of Joe’s last papers he sent me. Joe was always writing, since that was his second favorite thing to do. His fi rst love was teaching. Jo...

Most agent Communication Languages are no longer defined in terms of the agents’ mental attitudes, but in terms of social commitments. However, such social approaches have two drawbacks. First, the notion of commitment does not have a clear and unambiguous characterization. Second, commitments are completely unrelated to the agents’ reasoning. We remedy this situation by combining a BDI logic w...

As a possible generalization of Beck-Cohen superstatistical processes, we study non-Gaussian processes with temporal heterogeneity of local variance. To characterize the variance heterogeneity, we define log-amplitude cumulants and log-amplitude autocovariance and derive closed-form expressions of the log-amplitude cumulants for χ(2), inverse χ(2), and log-normal superstatistical distributions....

Generalized superstatistics, i.e., a "statistics of superstatistics," is proposed. A generalized superstatistical system comprises a set of superstatistical subsystems and represents a generalized hyperensemble. There exists a random control parameter that determines both the density of energy states and the distribution of the intensive parameter for each superstatistical subsystem, thereby fo...

UNLABELLED To compare the preventive treatment benefits of amitriptyline and aerobic exercise or amitriptyline alone in patients with chronic migraine. METHOD Sixty patients, both genders, aged between 18 and 50 years, with a diagnosis of chronic migraine, were randomized in groups called amitriptyline and aerobic exercise or amitriptyline alone. The following parameters were evaluated: heada...

Euler's identity equates the number of partitions any non-negative integer n into odd parts and distinct parts. Beck conjectured Andrews proved following companion to identity: excess in all over equals with exactly one even part (possibly repeated). Beck's original conjecture was followed by generalizations so-called “Beck-type” companions other identities. In this paper, we establish a collec...

In our article (Weisberg & Gopnik, 2013), we construct a unifying theory of imaginative processes, in which counterfactuals and pretend games share an underlying cognitive capacity. This theory allows us to explain why children pretend, why they create fantastical pretend worlds, and how pretend play and counterfactual reasoning can help children to learn about the causal structure of reality. ...

In 1981 Beck and Fiala proved an upper bound for the discrepancy of a set system of degree d that is independent of the size of the ground set. In the intervening years the bound has been decreased from 2d− 2 to 2d− 4. We improve the bound to 2d− log∗ d. MSC classes: 05D05, 11K38, 05C15
