(2009) recognized the specimens from cichlids fishes from Pánuco river as independent lineages and based on this phylogenetic framework Salgado-Maldonado (2013), described these specimens as a new species.Published as part of Pinacho-Pinacho, Carlos Daniel, Sereno-Uribe, Ana L., León, Gerardo Pérez-Ponce De & García-Varela, Martín, 2015, Checklist of the species of Neoechinorhynchus (Acanthocephala: Neoechinorhynchidae) in fishes and turtles in Middle-America, and their delimitation based on sequences of the 28 S rDNA, pp. 98-116 in Zootaxa 3985 (1) on page 106, DOI: 10.11646/zootaxa.3985.1.5, http://zenodo.org/record/24107
Two new species of Gyrodactylus von Nordmann, 1832 parasitizing Cnesterodon decemmaculatus (Poeciliidae) from the southern limit of the family in the Neotropical region
No full textIn this study, we followed an integrative taxonomy approach to describe two new species of Gyrodactylus von Nordmann, 1832, and to identify specimens of G. breviradix Vega, Razzolini, Arbetman, and Viozzi, 2019, all three collected from ten spotted live-bearer Cnesterodon decemmaculatus (Jenyns, 1842), an endemic and widespread poeciliid from the Pampean region, which is the southernmost occurring species of the Poeciliidae in the Americas. Gyrodactylids were first characterized morphologically and mophometrically, and when possible, sequences of the Internal Transcribed Spacers (ITS1-5.8S-ITS2) and the cytochrome oxidase II (COII) were used to delimit species. Gyrodactylus breviradix, Gyrodactylus marplatensis n. sp., and Gyrodactylus pampeanus n. sp. were found on the fins and body surface of C. decemmaculatus in La Tapera Creek, Mar del Plata, Buenos Aires province, Argentina. A phylogenetic analysis combining newly generated sequences of one of the new species, G. marplatensis n. sp., and of G. breviradix, along with those available in GenBank for a further 36 species of Gyrodactylus, revealed that G. marplatensis n. sp. is a sister taxon of Gyrodactylus decemmaculati Vega, Razzolini, Arbetman, and Viozzi, 2019. Genetic distances for the ITS and COII gene were estimated among Gyrodactylus spp. and further supported the validity of the new species. Overall, morphometric and molecular data coincided in delimiting the new taxa, thus demonstrating the value of integrative taxonomy for the erection of new species of Gyrodactylus and species identification.Fil: Taglioretti, Verónica.

Ethnic identity, political identity and ethnic conflict: simulating the effect of congruence between the two identities on ethnic violence and conflict
No full textThis thesis outlines and presents an alternative hypothetical process to the emergence of ethnic conflict. Ethnic conflicts, rather than being dependent upon pre-existing 'ancient hatreds', are instead the result of a congruence between ethnic and political identity which grants individuals the ability to use ethnicity to identify and eliminate political threats. This hypothesis is formed by the examination of three case studies of ethnic conflict: Lebanon, Northern Ireland and Croatia. This hypothesis is then formalised and tested using an agent based simulation in which agent interactions are dependent upon ethnic and political identity and the congruence between the two. As predicted there was a strong positive correlation between how accurately ethnic identity reflected political identity and the level of ethnically motivated violence in the simulation, although the relationship was not linear. Furthermore the effect of a shift in congruence was found to be roughly comparable to the effect of initialising agents with a moderate level of pre-existing ethnic antagonism

No full textAncient theology and new philosophies: Pierre-Daniel Huet against Descartes and Spinoza
No full textThis article analyses Pierre-Daniel Huet's reaction to the doctrines that he believed to favour atheism, Deism, and, generally, irreligion. Descartes and Spinoza, in particular, are guilty, according to Huet, of placing excessive confidence in the discerning power of reason and in the type of certitude it produces, which is incomparable to revealed truth and in no way superior to moral certitude that arises from authority and historical erudition. Huet counters Cartesian philosophy with sceptical fideism and opposes Spinozian exegesis by means of an innovative, although perhaps untimely, adaptation of the doctrine of ancient theology. Against the 'atheist' Spinoza and the cohort of deist thinkers, Huet intends to demonstrate that Moses is the author of the Pentateuch and the divulger of God's message to all peoples, in all times, and that, as a consequence, deist 'natural religion' is a partially corrupted version of the Mosaic doctrine

Competing models of socially constructed economic man : differentiating Defoe's Crusoe from the Robinson of neoclassical economics
No full textDaniel Defoe’s Robinson Crusoe has seldom been read as an explicitly political text. When it has, it appears that the central character was designed to warn the early eighteenth-century reader against political challenges to the existing economic order. Insofar as Defoe’s Crusoe stands for "economic man", he is a reflection of historically-produced assumptions about the need for social conformity, not the embodiment of any genuinely essential economic characteristics. This insight is used to compare Defoe’s conception of economic man with that of the neoclassical Robinson Crusoe economy. On the most important of the ostensibly generic principles espoused by neoclassical theorists, their "Robinson" has no parallels with Defoe’s Crusoe. Despite the shared name, two quite distinct social constructions serve two equally distinct pedagogical purposes. Defoe’s Crusoe extols the virtues of passive middle-class sobriety for effective social organisation; the neoclassical Robinson champions the establishment of markets for the sake of productive efficiency
Malware and Market Share
No full textThis article presents a game-theoretic model of the interaction between malware creators (hackers) and users. Users select and hackers target information technology platforms based upon each platform’s network externalities and security. In equilibrium, a platform’s market share among users and the distribution of malware across platforms are derived endogenously. In particular, a platform’s relative market share is shown to be the square root of the ratio of its competitor’s vulnerability to its own vulnerability. This provides a useful standard for guiding a platform’s security strategy and for characterizing platform competition on the basis of security. It is also consistent with the longstanding empirical folk wisdom that platform leaders must make increasing investments into cybersecurity in order to maintain market share. © The Author(s) 2018.
