Vertebrate Natural History Notes from Arkansas, 2019

Important observations of natural history often go unreported because they are not part of larger studies, but small details can provide insights that lead to interesting questions about ecological relationships or environmental change. We have compiled recent important observations of distribution, deformities, foods, parasites, and reproduction of various vertebrates. Included are a new record of Lake Sturgeon (Acipenser fulvescens), a new size record of mudpuppy (Necturus louisianensis), and a second observation of bilateral gynandromorphism in a Northern Cardinal (Cardinalis cardinalis). These unique observations continue to grow knowledge of vertebrate biology in Arkansas

Vertebrate Natural History Notes from Arkansas, 2020

Smaller details of natural history often go undocumented to science if those details are not parts of larger studies, but small details can provide insights that lead to interesting questions about ecological relationships or environmental change. We have compiled recent important observations of distribution and reproduction of fishes and mammals. Included are new distributional records of mammals, and observations of reproduction in several mammals for which few data exist in Arkansas. A rare record of the Long-tailed weasel, a special of special concern in Arkansas, is documented from Newton Co. We also provide evidence that Seminole bats likely reproduce in Arkansas

Mobile technology in mobile work: contradictions and congruencies in activity systems

Mobile technology and the information and communication services supported by it have become increasingly embedded in, and in some cases transformed, work and social activity and created new challenges for studying information systems. This paper focuses on the experience with mobile technology in an inherently mobile and information intensive work activity - policing. Drawing upon data from this context this paper makes two key sets of contributions. Empirically, we illuminate the congruencies and contradictions between mobile technology and mobile working, and the relationship between the two, revealing a state of change based upon dialectic interaction. We highlight several ways in which mobile technology has changed the nature of mobile work activity. Theoretically we advance the use of activity theory to better understand the changes of mobile technology mediated work. We extend traditional use of activity theory by adopting congruencies as an analytical lens, in addition to the approach of examining contradictions. The findings are applicable to other areas of mobile work and contribute to the body of knowledge concerning mobile technology mediated work
