A BIODIVERSITY SURVEY OF THE SOIL CRUSTS OF THE GEOGRAPHICALLY ISOLATED SAN NICHOLAS ISLAND, CALIFORNIA, USA AND DESCRIPTION OF SPECIES IN THREE GENERA (ATLANTICOTHIX, PYCNACRONEMA, KONICACRONEMA) PREVIOUSLY RESTRICTED TO BRAZIL USING A POLYPHASIC APPROACH TO CYANOBACTERIAL TAXONOMY
Get PDFSan Nicholas Island, California, USA is a geographically-isolated island that experiences a semiarid climate and exhibits significant topographic and geologic diversity. Access to the island is restricted to the public and, as a result, only one previous study has been done on the algal biodiversity of its biological soil crusts. The previous study used morphology as the sole basis of species identification, and it was the aim of this study to corroborate and expand upon the results by including molecular data. Using 16S rRNA and 16S–23S ITS sequences and phylogenetic analyses, a diverse set of taxa were identified and are presented herein. Multiple taxa were determined to be common to both studies based on morphological similarity, and several putative new genera and species were identified based on molecular analyses. Several genera were identified that had not been observed in the Northen Hemisphere, raising questions about the distribution of taxa at the genus and species level
Repeated Games in the Presence of Incomplete Information
Get PDFThere are many strategic situations at which a game theoretical framework should be used to analyze the equilibrium decisions at which the incomplete information annoy the process of deriving the certain rules for making decisions. In these cases, players use signals of each other\u27s to get proper decisions. For example, in economic environment, some macro-economic latent variables induce incomplete information. Morris and Shin (2000) referred this type of game as global game and studied one-shot type of it. However, in practical situations, it is a type of repeated game. In the current paper, following notations of Morris and Shin (2000), repeated games in the presence of incomplete information are studied. Using stochastic approximation technique for M-estimation of latent variable, the learning phenomenon is observed. Financial applications of proposed problem is presented. Finally conclusions are given
The Political Divergence of Ohio and Michigan
Get PDFOhio and Michigan are demographically similar states whose politics have diverged since 2016. This research aims to explain why these two Midwestern states have taken such different political paths in recent years. A comparative case study is used to examine a number of possible explanations. The results of this research show that institutional factors such as registration and voting laws, redistricting processes, and ballot measures have contributed to the political divergence of Ohio and Michigan. Further, data on policy preferences are compared to show that the differences between the states are not the result of different policy preferences among their citizens. This research concludes with a discussion of other possible factors and the implications of the findings on political parties and electoral competition in Ohio
CLI-FI AND CLASS Socioeconomic Justice in Contemporary American Climate Fiction
No full textSince its emergence in the late twentieth century, climate fiction—or cli-fi—has concerned itself as much with economic injustice and popular revolt as with rising seas and soaring temperatures. Indeed, with its insistent focus on redressing social disparities, cli-fi might reasonably be classified as a form of protest literature. As environmental crises escalate and inequality intensifies, literary writers and scholars alike have increasingly scrutinized the dual exploitations of the earth’s ecosystems and the socioeconomically disadvantaged.
Cli-Fi and Class focuses on the representation of class dynamics in climate-change narratives. With fifteen essays on the intersection of the economic and the ecological—addressing works ranging from the novels of Joseph Conrad, Cormac McCarthy, and Octavia Butler to the film Black Panther and the Broadway musical Hadestown —this collection unpacks the complex ways economic exploitation impacts planetary well-being, and the ways climatic change shapes those inequities in turn
