Risk and risk behavior form an important segment of the entrepreneurship literature. Entrepreneurial risk behavior has been studied with both trait and cognitive approaches, but the findings do not adequately explain either how entrepreneurs differ from non-entrepreneurs, or how different types of entrepreneurs can be specified in terms of their risk behavior. This paper is an attempt to address these issues by introducing two temporal attributes that we consider significant for understanding risk behavior, given that risk is inherently embedded in time. First, we suggest the notion of risk horizon, differentiating short-range risk from long-range risk. Second, we examine the risk behavior of entrepreneurs in terms of their individual future orientation, in tandem with their risk propensity. We propose a temporal framework that seeks to explain, at once, the different types of risk behavior among entrepreneurs as well as the distinction between entrepreneurs and non-entrepreneurs. The framework is also applied to networking and alliancing activities of entrepreneurs. Finally, a number of propositions are developed to facilitate empirical testing of the insights implicit in the temporal framework of entrepreneurial risk behavior.

The paper presents a review on a monograph by O.S. Likhacheva, concerned with the analysis of different types of weapons and reconstruction of some aspects of the warfare of the tribes of the Forest-Steppe Altai in the 8th–1st centuries B.C., which contains a representative album of illustrations, including photographs and drawings of artifacts, artistic interpretations of weapons and images of warriors, made by the author. O.S. Likhacheva carried out a meticulous analysis of numerous categories of weapons and their fragments. However, in the opinion of the author of this review, for a considerable part of the presented inventory there is a lack of context description of the finds in the ceremonial burial complexes. This leads to the description of the votive weapons as combative, ceremonially broken items as intact, and fragmentary separate armor-clad plates as a complete armor suit. Certain selectivity of the author in writing the historiography section narrows the attention of the researcher on only one region under consideration, thus ignoring the trans-cultural nature of some types of the weapons of short-range and long-range combat among the nomads of the Central Asia in the 8th–1st centuries B.C., as well as the body of the material from the monuments of the Novosibirsk Ob region which fit in the topic area of the research. The author recommends the book of O.S. Likhacheva to all interested in the history and archaeology of Altai Krai and Upper Ob region.

True, there may be two language-processing systems, lexicon and syntax. However, could we not say more than that they are computationally and linguistically distinct? Where are they in the brain, why are they where they are, and how can their distinctness and functional properties be explained by biological principles? A brain model of language is necessary to answer these questions. One view is that two different types of corticocortical connections are most important for storing rules and their exceptions: short-range connections within the perisylvian language cortex and long-range connections between this region and other areas. Probabilities of neuroanatomical connections plus associative learning principles explain why different connection bundles specialize in rule storage versus exception learning. Linguistic issues related to language change and plural formation in German are addressed in closing.

AbstractThe structural response of Dy2TiO5 oxide under swift heavy ion irradiation (2.2 GeV Au ions) was studied over a range of structural length scales utilizing neutron total scattering experiments. Refinement of diffraction data confirms that the long-range orthorhombic structure is susceptible to ion beam-induced amorphization with limited crystalline fraction remaining after irradiation to 8 × 1012 ions/cm2. In contrast, the local atomic arrangement, examined through pair distribution function analysis, shows only subtle changes after irradiation and is still described best by the original orthorhombic structural model. A comparison to Dy2Ti2O7 pyrochlore oxide under the same irradiation conditions reveals a different behavior: while the dysprosium titanate pyrochlore is more radiation resistant over the long-range with smaller degree of amorphization as compared to Dy2TiO5, the former involves more local atomic rearrangements, best described by a pyrochlore-to-weberite-type transformation. These results highlight the importance of short-range and medium-range order analysis for a comprehensive description of radiation behavior.

We give a short summary on how to combine and extend results of Combes and Hislop [2] (short range Anderson model with additional displacements), Kirsch, Stollmann and Stolz [13] and [14] (long range Anderson model without displacements) to get localization in an energy interval above the infimum of the almost sure spectrum for a continuous multidimensional Anderson model including long range potentials and displacements.
