  • In his deliberately provocative — and deeply nihilistic — new book, “Reality Hunger,” the onetime novelist David Shields asserts that fiction “has never seemed less central to the culture’s sense of itself.”
  • Mr. Shields’s book consists of 618 fragments, including hundreds of quotations taken from other writers like Philip Roth, Joan Didion and Saul Bellow — quotations that Mr. Shields, 53, has taken out of context and in some cases, he says, “also revised, at least a little — for the sake of compression, consistency or whim.”
  • It’s also a question, as Mr. Lanier, 49, astutely points out in his new book, “You Are Not a Gadget,” of how online collectivism, social networking and popular software designs are changing the way people think and process information, a question of what becomes of originality and imagination in a world that prizes “metaness” and regards the mash-up as “more important than the sources who were mashed.”

  • Mr. Lanier’s book, which makes an impassioned case for “a digital humanism,” is only one of many recent volumes to take a hard but judicious look at some of the consequences of new technology and Web 2.0. Among them are several prescient books by Cass Sunstein, 55, which explore the effects of the Internet on public discourse; Farhad Manjoo’s “True Enough,” which examines how new technologies are promoting the cultural ascendancy of belief over fact; “The Cult of the Amateur,” by Andrew Keen, which argues that Web 2.0 is creating a “digital forest of mediocrity” and substituting ill-informed speculation for genuine expertise; and Nicholas Carr’s book “The Shallows” (coming in June), which suggests that increased Internet use is rewiring our brains, impairing our ability to think deeply and creatively even as it improves our ability to multitask.
  • Steven Johnson, a founder of the online magazine Feed, for instance, wrote in an article in The Wall Street Journal last year that with the development of software for Amazon.com’s Kindle and other e-book readers that enable users to jump back and forth from other applications, he fears “one of the great joys of book reading — the total immersion in another world, or in the world of the author’s ideas — will be compromised.” He continued, “We all may read books the way we increasingly read magazines and newspapers: a little bit here, a little bit there.”

  • Encoding of working memory involves the spiking of individual neurons induced by sensory input, which persists even after the sensory input disappears (Jensen and Lisman 2005; Fransen et al. 2002). Encoding of episodic memory involves persistent changes in molecular structures that alter synaptic transmission between neurons. Examples of such structural changes include long-term potentiation (LTP) or spike-timing-dependent plasticity (STDP). The persistent spiking in working memory can enhance the synaptic and cellular changes in the encoding of episodic memory (Jensen and Lisman 2005).
  • Recent functional imaging studies detected working memory signals in both medial temporal lobe (MTL), a brain area strongly associated with long-term memory, and prefrontal cortex (Ranganath et al. 2005), suggesting a strong relationship between working memory and long-term memory. However, the substantially more working memory signals seen in the prefrontal lobe suggest that this area play a more important role in working memory than MTL (Suzuki 2007).
  • Consolidation and reconsolidation. Short-term memory (STM) is temporary and subject to disruption, while long-term memory (LTM), once consolidated, is persistent and stable. Consolidation of STM into LTM at the molecular level presumably involves two processes: synaptic consolidation and system consolidation. The former involves a protein synthesis process in the medial temporal lobe (MTL), whereas the latter transforms the MTL-dependent memory into an MTL-independent memory over months to years (Ledoux 2007). In recent years, such traditional consolidation dogma has been re-evaluated as a result of the studies on reconsolidation. These studies showed that prevention after retrieval affects subsequent retrieval of the memory (Sara 2000). New studies have shown that post-retrieval treatment with protein synthesis inhibitors and many other compounds can lead to an amnestic state (Nadel et al. 2000b; Alberini 2005; Dudai 2006). These findings on reconsolidation fit with the behavioral evidence that retrieved memory is not a carbon copy of the initial experiences, and memories are updated during retrieval.

  • Physical exercise, particularly continuous aerobic exercises such as running, cycling and swimming, has many cognitive benefits and effects on the brain. Influences on the brain include increases in neurotransmitter levels, improved oxygen and nutrient delivery, and increased neurogenesis in the hippocampus. The effects of exercise on memory have important implications for improving children's academic performance, maintaining mental abilities in old age, and the prevention and potential cure of neurological diseases.
  • At the Center for Cognitive Science at Ohio State University, researchers have found that memory accuracy of adults is hurt by the fact that they know more, and have more experience than children, and tend to apply all this knowledge when learning new information. The findings appeared in the August 2004 edition of the journal Psychological Science.
  • Interference can hamper memorization and retrieval. There is retroactive interference, when learning new information makes it harder to recall old information[59] and proactive interference, where prior learning disrupts recall of new information. Although interference can lead to forgetting, it is important to keep in mind that there are situations when old information can facilitate learning of new information. Knowing Latin, for instance, can help an individual learn a related language such as French – this phenomenon is known as positive transfer.[60]
  • Methods to optimize memorization[edit] Memorization is a method of learning that allows an individual to recall information verbatim. Rote learning is the method most often used. Methods of memorizing things have been the subject of much discussion over the years with some writers, such as Cosmos Rossellius using visual alphabets. The spacing effect shows that an individual is more likely to remember a list of items when rehearsal is spaced over an extended period of time. In contrast to this is cramming which is intensive memorization in a short period of time. Also relevant is the Zeigarnik effect which states that people remember uncompleted or interrupted tasks better than completed ones. The so-called Method of loci uses spatial memory to memorize non-spatial information.[72]

Circumcision of the Heart in Leviticus and Deuteronomy: Divine Means for Resolving Curs... - 0 views

  • These three uses of “uncircumcised” imply that the foreskin is an impediment or obstacle to hearing, speaking, and producing good fruit. That is, the state of being uncircumcised impedes something, which, if it did not have the foreskin, would otherwise be prepared for true function and vitality. But since it has the foreskin, it is impeded

      Excellent assessment up to this point. The conclusion "and will die," however, has no clear basis in the evidence for uncircumcised ears, lips, or fruit.
  • There is a progression in Leviticus from “outward” holiness to “inward” holiness or better, from the holiness symbolized in sacrifice, cult, and purity laws to holiness exhibited in the obedience of a prepared and consecrated people which Leviticus 17-27 envisions.
  • The foreskin of their heart was the cause of their stubbornness in 24:10-23, which led to God’s curse coming upon them in exile. They became as the “foreskined fruit trees” in Leviticus 19:23 that were unable to yield fruit. Their hearts still had the foreskin, the impediment or obstacle which prevented them from vital covenant faithfulness and ensuing blessing
  • ...5 more annotations...
  • Within this scheme, Leviticus presents the humbling of the foreskin of the heart as the resolution to the stubborn heart which brought the people into exile. Heart circumcision will bring the blessing of restoration.
  • It is in the context of the covenant curses that our reference to heart circumcision occurs in Leviticus 26:41, revealing that Israel had an internal heart problem which led them to curse God and therefore undergo his covenant curses.
  • Leviticus 26 describes the outworking of the blessing, curse-exile, and return from exile
  • Deuteronomy presents circumcision of the heart as important means for attaining the Deuteronomic vision of loyalty from a devoted heart.4

    "Joyce Valenza Ph.D On the librarian: What's the point . . ? The Twitter conversation April 30, 2009 @karlfisch: What's the point of having a media specialist if they aren't specialists in the media forms of the day? I was nearly finished copying and pasting, figuring out how best to post Tuesday's Twitter conversation, when I discovered that Karl Fisch (@karlfisch), who kinda started it all, already took care of that. (You likely know of Karl's very popular and provocative videos.) I am still not sure how best to frame this conversation on the place of the information/media specialist in today's school. What is clear is that a lot of smart people--people who are out there teaching, speaking, moving, and shaking--are disappointed in what they see when they see school librarians. Either we have a perception problem or we need to do some serious retooling. I'd say we have to deal with both. In a hurry. Being an information (or media) specialist today means being an expert in how information and media flow TODAY! It is about knowing how information and media are created and communicated. How to evalute, synthesize, and ethically use information and media in all their varied forms. It is about being able to communicate knowlege in new ways for new audiences using powerful new information and communication tools. Forgive me if it hurts. In my mind, if you are not an expert in new information and communication tools, you are NOT a media specialist for today. Tuesday's conversation happened in the open, on Twitter. We need to be aware that these conversations are happening where we cannot hear them--at conferences, at Board and cabinet meetings. We also need to make sure that our voices are heard and that we hear the voices of others in places like Twitter, where so many educational leaders and thinkers are chatting about us and many other things. I've selected the remarks that resonated loudest for me. (I've shuffled a bit, but you can visit Karl'

  • Or maybe the page has been moved and something else is where it used to be. This is known as “content drift,”
  • For the law and for the courts, link rot and content drift, which are collectively known as “reference rot,” have been disastrous.
  • According to a 2014 study conducted at Harvard Law School, “more than 70% of the URLs within the Harvard Law Review and other journals, and 50% of the URLs within United States Supreme Court opinions, do not link to the originally cited information.”
  • one in five links provided in the notes suffers from reference rot
  • 1961, in Cambridge, J. C. R. Licklider, a scientist at the technology firm Bolt, Beranek and Newman, began a two-year study on the future of the library, funded by the Ford Foundation and aided by a team of researchers that included Marvin Minsky, at M.I.T.
  • Licklider envisioned a library in which computers would replace books and form a “network in which every element of the fund of knowledge is connected to every other element.”
  • Licklider’s two-hundred-page Ford Foundation report, “Libraries of the Future,” was published in 1965.
  • Kahle enrolled at M.I.T. in 1978. He studied computer science and engineering with Minsky.
  • Vint Cerf, who worked on ARPAnet in the seventies, and now holds the title of Chief Internet Evangelist at Google, has started talking about what he sees as a need for “digital vellum”: long-term storage. “I worry that the twenty-first century will become an informational black hole,” Cerf e-mailed me. But Kahle has been worried about this problem all along.
  • The Internet Archive is also stocked with Web pages that are chosen by librarians, specialists like Anatol Shmelev, collecting in subject areas, through a service called Archive It, at archive-it.org, which also allows individuals and institutions to build their own archives.
  • Illien told me that, when faced with Kahle’s proposal, “national libraries decided they could not rely on a third party,” even a nonprofit, “for such a fundamental heritage and preservation mission.”
  • screenshots from Web archives have held up in court, repeatedly.
  • Perma.cc has already been adopted by law reviews and state courts; it’s only a matter of time before it’s universally adopted as the standard in legal, scientific, and scholarly citation.
  • It’s not possible to go back in time and rewrite the HTTP protocol, but Van de Sompel’s work involves adding to it. He and Michael Nelson are part of the team behind Memento, a protocol that you can use on Google Chrome as a Web extension, so that you can navigate from site to site, and from time to time. He told me, “Memento allows you to say, ‘I don’t want to see this link where it points me to today; I want to see it around the time that this page was written, for example.’ ”

  • GRADUATE education is the Detroit of higher learning. Most graduate programs in American universities produce a product for which there is no market (candidates for teaching positions that do not exist) and develop skills for which there is diminishing demand (research in subfields within subfields and publication in journals read by no one other than a few like-minded colleagues), all at a rapidly rising cost (sometimes well over $100,000 in student loans).

  • However, e-readers must be significantly improved to have the same value in a teaching environment as traditional paper texts, participants said.
  • but they also said the ability to highlight directly on traditional text, to take notes and flip pages for ease in navigation suffers in the e-reader.
  • With hopes of assisting industry with the refinement of e-readers, and providing useful information to other academic institutions considering the devices, information and data from the one-time pilot have been compiled on an Office of Information Technology (OIT) website.
  • ...5 more annotations...
  • About 65 percent of the participants in the pilot said they would not buy another e-reader now if theirs was broken. Almost all the participants said they were interested in following the technology to its next stages, because they think a device that works well in academia would be worth having.
  • "I found the device difficult to use and not conducive to academic purposes," he said, and added, "But I can see how it can be used for pleasure reading."
  • What they liked best about the devices was: the battery life, the wireless connection and the portability of the e-reader; the fact that all the course reading was on one device; the ability to search for content; and the legibility of the screen, including the fact it could be read in full sunlight. The top five suggestions students had for improving e-readers were: improving the ability to highlight and annotate PDF files; improving the annotation tools; providing a folder structure to keep similar readings together; improving the highlighting function; and improving the navigation within and between documents on the reader (including having more than one document open at the same time for comparison).
  • "The Kindle would be better for an academic setting if the PDF format worked more effectively,"
  • "There would be a greater benefit realized if the devices could develop a better way to deliver the ubiquitous PDF document, which is used by many journals and libraries to deliver documents, and is the common format in which dissertations and theses are published and read by faculty," Temos said. "Some students said they spent a considerable amount of time printing PDF documents during the semester, and hardly ever referred back to them once the semester was over. I don't expect that is unusual."

  • An elephant in the room” refers to an obvious problem that remains unmentioned and is suffered silently. Music education has many such ‘elephants’ in its classrooms, and music teacher educators often seem resigned to working around them or worry about confronting them. Others are in collusion with these ‘elephants.’
  • This problem stems from the elephantine belief that a music educator must first and foremost be a good musician and that such training is sufficient to being a good teacher.
