Reformismo social em John R. Commons

This research aims to discuss aspects of the thought of John R. Commons regarding their engagement with the reform of capitalism. He focuses on his interpretation of the socioeconomic context of American capitalism, which led him to distance himself from the Marxist revolutionary praxis and the authoritarian reformism offered by the variant of European fascism. Based on extensive literature review, the research rebuild through a historical and theoretical context, his thinking and show the evolution of his ideas throughout his life. Recreating the terms in which Commons defended his reformist project, called him reasonable capitalism.

Altered Behavior in Bats Affected by White-Nose Syndrome

WNS-affected bats did so over similar time frames as WNSunaffected bats. The behaviors of bats with WNS did not change as drastically as expected. Thereseems to be little to no effect on their ability to fly/forage until much later stages of the disease when they are likely near death. WNS-affected bats are grooming more which could be altering the way they use energy reserves during hibernation possibly leading tostarvation and eventually death. The decreased likelihood of arousals in response to external cues may be the result of spending more energy during previous and increasingly frequent arousals. While it is clear that WNS does result in changes in behavior whether these changes are directly in response to fungal skin infection or to some other component of the syndrome such as decreased energy availability or loss of homeostasis is unknown. bat behavior, white-nose syndrome, behavior, video surveillance, arousal patterns White-Nose Syndrome (WNS) is a disease of hibernating bats caused by the fungal pathogen Geomyces destructans. The fungus, which was first noted in 2006, invades bats wings and other exposed membranes, eventually resulting in death. Researchers have yet to understand many aspects of this disease, including basic etiology and epidemiology. There is also a lack of information on how fungal infection may change the behavior of healthy bats during hibernation or how changes in behavior may influence disease progression. Based upon the physiological changes that are known to occur in affected bats, and upon anecdotal observations of aberrant behavior in these bats, I hypothesized that WNS would significantly change the behavior of the little brown myotis (Myotis lucifugus). My research examined the behavior of hibernating bats during arousals from torpor. I compared WNS-affected and unaffected bats, in the field and incaptivity, using motion-sensitive infrared cameras. Flight maneuverability and echolocation were also tested between WNS-affected and unaffected bats during arousalsfrom hibernation to detect changes in the bats' ability to perform basic locomotion or potentially catch insect prey. Lastly, hibernating bats were artificially disturbed and theirarousal patterns were monitored to examine changes in the response to external stimuli between WNS-affected and unaffected bats.Bats with WNS groomed for longer periods of time after arousing from torpor, both in the field and in captivity. They also engaged in longer periods of any sort of activity during these arousals. There were no changes in acoustical signaling during flight tests and changes in flight maneuverability were only found in bats were seen staging" near the entrance of the mine which is itself a unique behavior exhibited by affected bats. At this point these bats were likely near death and could barely fly at all. In response toexternal stimuli bats with WNS were less likely to arouse than unaffected bats. However when they did arouse WNS-affected bats did so over similar time frames as WNSunaffected bats. The behaviors of bats with WNS did not change as drastically as expected.

The tragedy of the commons in evolutionary biology

Garrett Hardin's tragedy of the commons is an analogy that shows how individuals driven by self-interest can end up destroying the resource upon which they all depend. The proposed solutions for humans rely on highly advanced skills such as negotiation, which raises the question of how non-human organisms manage to resolve similar tragedies. In recent years, this question has promoted evolutionary biologists to apply the tragedy of the commons to a wide range of biological systems. Here, we provide tools to categorize different types of tragedy and review different mechanisms, including kinship, policing and diminishing returns that can resolve conflicts that could otherwise end in tragedy. A central open question, however, is how often biological systems are able to resolve these scenarios rather than drive themselves extinct through individual-level selection favouring self-interested behaviours.

Resolving the tragedy of the commons: the feedback between intraspecific conflict and population density

Competition and conflict among individuals can favour exploitative strategies that undermine the common good. Theory suggests that this can lead to a tragedy of the commons and ultimately population extinction, a phenomenon known as evolutionary suicide. Here, I present a model of the evolutionary tragedy of the commons that explicitly considers the population dynamics where individuals invest in individually costly competitive traits. In the simplest form, this supports the notion that selection for high levels of conflict can cause evolutionary suicide. However, as competition comes with survival and fecundity costs, a feedback between the investment in competition and population density can act to reduce the level of conflict and prevent the population from going extinct. This suggests that the interaction between population ecology and the evolution of competition and conflict among individuals may be an important mechanism in resolving the level of competition and conflict among individuals.

Creative Commons International The International License Porting Project

When Creative Commons (CC) was founded in 2001, the core Creative Commons licenses were drafted according to United States Copyright Law. Since their first introduction in December 2002, Creative Commons licenses have been enthusiastically adopted by many creators, authors, and other content producers – not only in the United States, but in many other jurisdictions as well. Global interest in the CC licenses prompted a discussion about the need for national versions of the CC licenses. To best address this need, the international license porting project (“Creative Commons International” – formerly known as “International Commons”) was launched in 2003. Creative Commons International works to port the core Creative Commons licenses to different copyright legislations around the world. The porting process includes both linguistically translating the licenses and legally adapting the licenses to a particular jurisdiction such that they are comprehensible in the local jurisdiction and legally enforceable but concurrently retain the same key elements. Since its inception, Creative Commons International has found many supporters all over the world. With Finland, Brazil, and Japan as the first completed jurisdiction projects, experts around the globe have followed their lead and joined the international collaboration with Creative Commons to adapt the licenses to their local copyright. This article aims to present an overview of the international porting process, explain and clarify the international license architecture, its legal and promotional aspects, as well as its most recent challenges.

Creative Commons Olympics. How Big Media is Learning to License From Amateur Authors

NBC Universal’s decision to use Creative Commons-licensed photographs in an Olympic broadcast is an example of how media conglomerates are experimenting with collaboration with amateurs, but it also reveals potential problems of letting non-lawyers negotiate copyright licensing agreements. In the process, NBC’s producers nearly opened the door for a multimillion-dollar infringement law suit. To avoid such pitfalls, media companies need to adopt policies and best practices for using amateur licensed works. These guidelines should instruct how a production can attribute collaborating authors and how the Open Content licensing terms affect the licensing of the productions. The guidelines should also instruct how producers can seek alternative licensing arrangements with amateurs and contribute back to the Open Content community.
