      which is why it is so crucial to examine in our classrooms-helping our students develop fair judgment when using technoligies.
  • if the user “transforms” the material in some way, repurposing it in a new media composition, for instance, then fair use likely applies.
  • or did it just repeat the work for the same intent and value as the original?
  • Students’ use of copyrighted material should not be a substitute for creative effort.
  •  
    from NCTE's Monthly Intellectual Property Reports, Troy Hicks writes: "In November 2008, educators were introduced to the "Code of Best Practices in Fair Use for Media Literacy Education," and our concept of how to deal with copyright issues in the classroom has, literally, been transformed. As the official policy of NCTE related to fair use in the teaching of English, it is a document worth our attention as students learn to comprehend and compose texts utilizing a variety of forms of media."

Journal of Cerebral Blood Flow & Metabolism - Multiple Microvascular and Astroglial 5-H... - 0 views

  • Physiologic and anatomic evidence suggest that 5-hydroxytryptamine (5-HT) neurons regulate local cerebral blood flow and blood-brain barrier permeability.
  • capillary endothelial cells exhibited mRNA for the h5-HT1D and for the 5-HT7 receptors whereas microvascular smooth muscle cells, in addition to h5-HT1D and 5-HT7, also showed polymerase chain reaction products for h5-HT1B receptors. Expression of 5-HT1F and 5-HT2A receptor mRNAs was never detected in any of the microvascular cell cultures. In contrast, messages for all 5-HT receptors tested were detected in human brain astrocytes with a predominance of the 5-HT2A and 5-HT7 subtypes. In all cultures, sumatriptan inhibited (35–58%, P < .05) the forskolin-stimulated production of cyclic AMP, an effect blocked by the 5-HT1B/1D receptor antagonists GR127935 and GR55562. In contrast, 5-carboxamidotryptamine induced strong increases (≥ 400%, P < .005) in basal cyclic AMP levels that were abolished by mesulergine, a nonselective 5-HT7 receptor antagonist. Only astroglial cells showed a ketanserin-sensitive increase (177%, P < .05) in IP3 formation when exposed to 5-HT. These results show that specific populations of functional 5-HT receptors are differentially distributed within the various cellular compartments of the human cortical microvascular bed, and that human brain astroglial cells are endowed with multiple 5-HT receptors. These findings emphasize the complex interactions between brain serotonergic pathways and non-neuronal cells within the CNS and, further, they raise the possibility that some of these receptors may be activated by antimigraine compounds such as brain penetrant triptan derivatives.

A short introduction concerning the implementation of the Horizon system at t... - 4 views

  • Horizon is a third generation system
  • marketed by Ameritech Library Services, a subsidiary of the Ameritech Corporation, one of the world's largest communication companies
  • new system Horizon was built on the Marquis, Dynix library system, and is being developed by Ameritech Library Service in collaboration with the University of Chicago and Indiana University. It was first introduced in the USA in 1991
  • ...7 more annotations...
  • Horizon is a fully integrated client/server library management system, providing a graphical user interface for the library, and offering the functionality and standards required for an open system, including Web access, Z39.50 standard for information exchange, the TCP/IP communication standard, UNIX and Windows NT for portability. Horizon uses the SQL database management system, available from Sybase or Microsoft.
  • the main hardware is a SUN computer Sparc Server 1000 with a UNIX Solaris 2.5 operating system
  • the centre of any library system is the cataloguing module.
  • Cataloguing and Authority Control contain the bibliographic database used by all Horizon modules
  • project will contain four stages of activity. Three of them include:
  • the preparation of standardised cataloguing rules and their implementation working out subject classification exchange of records among different systems preparation of legal and financial responsibilities collecting money for buying software and technical equipment etc. (we have already received $705,000 from the Mellon Foundation) implementation of system testing of the National Catalogue module schedule preparation for creation of databases users' training
  • Generally speaking, the main points of plan in Nicholas Copernicus University Library have been successfully realised. The progress is visible. Since September 1998 new modules have been implemented and tested. In the opinion of our users they work quite well. Of course, problems arise from time to time, and sometimes they are quite troublesome, but they are solved on a daily basis.

COPPA and Schools: The (Other) Federal Student Privacy Law, Explained - Education Week - 4 views

  • In a nutshell, COPPA requires operators of commercial websites, online services, and mobile apps to notify parents and obtain their consent before collecting any personal information on children under the age of 13. The aim is to give parents more control over what information is collected from their children online.
  • This law directly regulates companies, not schools. But as the digital revolution has moved into the classroom, schools have increasingly been put in the middle of the relationship between vendors and parents.
  • In some cases, companies may try to shift some of the burden of COPPA compliance away from themselves and onto schools
  • ...15 more annotations...
  • “That is not without risk, and COPPA has a whole lot of gray area that gives school attorneys pause.”
  • Less clear, though, is whether COPPA covers information such as IP (internet protocol) address, device identification number, the type of browser being used, or other so-called metadata that can often be used to identify users.
  • some school lawyers have taken the FTC’s previous guidance to mean that their districts must get consent from every single parent, for every single product that collects information online from young children.
  • First, according to the FTC, schools can grant consent on behalf of parents only when the operator of the website, online service, or app in question is providing a service that is “solely for the benefit of students and the school system” and is specific to “the educational context.”
  • How are schools supposed to determine if a website or app is strictly educational?
  • will any information collected from children under 13 be used or shared for commercial purposes unrelated to education? Are schools allowed to review the information collected on students? Can schools request that student info be deleted? If the answers to that second group of questions are, respectively, yes, no, or no, schools are not allowed to grant consent on behalf of parents, according to the FTC.
  • Many vendors also allow third-party trackers (usually related to analytics or advertising) to be embedded into their sites and services.
  • How do schools notify parents and get their consent under COPPA?
  • Often through an Acceptable Use Policy or similar document that is sent home to parents at the beginning of the school year, said Fitzgerald of Common Sense Media.
  • Even better, Fitzgerald said, is when schools provide a detailed list of exactly what websites/online services/apps students will be using, and what the information practices of each are.
  • some privacy experts say that a one-time, blanket sign-off at the beginning of the school year may not be considered valid notification and consent under COPPA, especially if it doesn’t list the specific online services that children will be using.
  • responsibility for deciding “whether a particular site’s or service’s information practices are appropriate” not be delegated to teachers.
  • Many districts do in fact have that kind of review-and-approval process.
  • One is “click-wrap agreements.” Often, these are the kinds of agreements that almost all of us are guilty of just clicking through without actually reading
