Julia Kristeva - 5 views

  • Theories of the body are particularly important for feminists because historically (in the humanities) the body has been associated with the feminine, the female, or woman, and denigrated as weak, immoral, unclean, or decaying.
    • Christopher Williams
       
      Feminism and post-structuralism operate in binaries: good/evil, truth/lie, love/hate, man/not man(woman)
  • Kristeva emphasizes the maternal function and its importance in the development of subjectivity and access to culture and language. While Freud and Lacan maintain that the child enters the social by virtue of the paternal function, specifically paternal threats of castration, Kristeva asks why, if our only motivation for entering the social is fear, more of us aren't psychotic?
  • Kristeva argues that there are three phases of feminism. She rejects the first phase because it seeks universal equality and overlooks sexual differences. She implicitly criticizes Simone de Beauvoir and the rejection of motherhood; rather than reject motherhood Kristeva insists that we need a new discourse of maternity.

This is How Apple Changes Education, Forever - 4 views

  • have a theory, though. I think Apple will introduce a Classroom iPad for $199 before the year is out. Pure speculation? Absolutely. However, considering how serious Apple is about improving the state of education, this makes real sense. I imagine it will be a 1024×768, 9.7-inch screen (while the iPad 3 gets the Retina Display and maybe changes size or shape), with a plastic back and rugged shell that only the school can remove. There will be a single, rear-facing camera, and the tablet will be locked down with access to the iBooks 2 app and pre-loaded textbooks. Safari will come pre-loaded, but it’ll run through Apple’s special proxy education server (yes, I’m making that up, too).There will be no App Store or iTunes account associated with it and schools will manage all of them centrally.
  •  
    Be interesting to use this in a class discussion on the viability of the iPad or other similar devices as content consumption and/or creation devices along side the debate that has to do with how textbooks are changing.

SLAVERY | The Handbook of Texas Online| Texas State Historical Association (TSHA) - 26 views

  • SLAVERY. Texas was the last frontier of slavery in the United States. In fewer than fifty years, from 1821 to 1865, the "Peculiar Institution," as Southerners called it, spread over the eastern two-fifths of the state. The rate of growth accelerated rapidly during the 1840s and 1850s. The rich soil of Texas held much of the future of slavery, and Texans knew it. James S. Mayfield undoubtedly spoke for many when he told the Constitutional Convention of 1845 that "the true policy and prosperity of this country depend upon the maintenance" of slavery. Slavery as an institution of significance in Texas began in Stephen F. Austin's colony. The original empresario commission given Moses Austin by Spanish authorities in 1821 did not mention slaves, but when Stephen Austin was recognized as heir to his father's contract later that year, it was agreed that settlers could receive eighty acres of land for each bondsman brought to Texas. Enough of Austin's original 300 families brought slaves with them that a census of his colony in 1825 showed 443 in a total population of 1,800. The independence of Mexico cast doubt on the future of the institution in Texas. From 1821 until 1836 both the national government in Mexico City and the state government of Coahuila and Texas threatened to restrict or destroy black servitude. Neither government adopted any consistent or effective policy to prevent slavery in Texas; nevertheless, their threats worried slaveholders and possibly retarded the immigration of planters from the Old South. In 1836 Texas had an estimated population of 38,470, only 5,000 of whom were slaves.

How About Better Parents? - NYTimes.com - 97 views

  • “Fifteen-year-old students whose parents often read books with them during their first year of primary school show markedly higher scores in PISA 2009 than students whose parents read with them infrequently or not at all. The performance advantage among students whose parents read to them in their early school years is evident regardless of the family’s socioeconomic background. Parents’ engagement with their 15-year-olds is strongly associated with better performance in PISA.”

The Drugs of Work-Performance Enhancement - Atlantic Mobile - 13 views

  • From time to time, I witnessed the shadows of depression, which I’ve read that others on the drug sometimes succumb to. Fortunately, I had the wherewithal to know this was a chemically induced darkness—one that reminded me of the sharp mood swings associated with Decadron, a corticosteroid once prescribed to me for a subdural hematoma resulting from a head injury. After two weeks of usage with this steroid, I felt suicidal. My physician had not warned me of this side effect. But with Adderall, I had knowledge aplenty and knew that once I stopped it, my depression would quickly lift. I also know that not everyone has that kind of previous experience or perspective, which is when folks get into deep trouble.

True Grit - Association for Psychological Science - 55 views

    • anonymous
       
      I think it's fascinating that the authors use this "metaphor of achievement" in their article. Many cultural artifacts support this idea of grit, and how hard work and persistence can often help learners achieve their long-term goals.
  • Thus, the growing experimental literature on strategies that facilitate regulation of attention, emotion, and behavior in the presence of immediate temptations, could be relevant to grit and its cultivation.

Technology Integration Matrix - 171 views

  •  
    The Technology Integration Matrix (TIM) illustrates how teachers can use technology to enhance learning for K-12 students. The TIM incorporates five interdependent characteristics of meaningful learning environments: active, constructive, goal directed (i.e., reflective), authentic, and collaborative (Jonassen, Howland, Moore, & Marra, 2003). The TIM associates five levels of technology integration (i.e., entry, adoption, adaptation, infusion, and transformation) with each of the five characteristics of meaningful learning environments. Together, the five levels of technology integration and the five characteristics of meaningful learning environments create a matrix of 25 cells.

Psilocybin (magic mushrooms) - 0 views

  • The biosinthetic path that allow Psilocybin to be produced by mushrooms is as follow:
  • The several analogyes with triptophan aminoacid, with whom psilocybin has common origines are probably at the base of psilocybin ability to induced psychedelich alteration on humans.
  • Amino acids, including tryptophan, act as building blocks in protein biosynthesis. In addition, tryptophan functions as a biochemical precursor for many compounds like serotonin Serotonin (a neurotransmitter), synthesized via tryptophan hydroxylase. Serotonin, in turn, can be converted to melatonin (a neurohormone), via N-acetyltransferase and 5-hydroxyindole-O-methyltransferase activities

  • it's been noticed that psilocyn can indirectly raise dopamine concentration withing the basal ganglia.
  • Almost 50% of oral psilocybin is absorbed by stomach and gut; from here is lead to liver, where it's converted in psilocin, pharmacologically active form, that can furtherly be glucoronated and escreted with urine or converted in other psilocinics metabolites.
  • In rats, the median lethal dose (LD50) when administered orally is 280 milligrams per kilogram (mg/kg), approximately one and a half times that of caffeine. When administered intravenously in rabbits, psilocybin's LD50 is approximately 12.5 mg/kg
  • traces of the compund can be detected in unine even after 7 days.
  • Clinical studies show that psilocin concentrations in the plasma of adults average about 8 µg/liter within 2 hours after ingestion of a single 15 mg oral psilocybin dose; psychological effects occur with a blood plasma concentration of 4–6 µg/liter. Psilocybin is about 100 times less potent than LSD on a weight per weight basis, and the physiological effects last about half as long.
  • Within 24 hours from administration 65% of the alucinogen is escreted by urine, while another 15-20% is excreted by bile and feces.
  • Monoamine oxidase inhibitors (MAOI) have been known to prolong and enhance the effects of psilocybin. Alcohol consumption may enhance the effects of psilocybin, because acetaldehyde, one of the primary breakdown metabolites of consumed alcohol, reacts with biogenic amines present in the body to produce MAOIs related to tetrahydroisoquinoline and β-carboline. Tobacco smokers can also experience more powerful effects with psilocybin, because tobacco smoke exposure decreases levels of MAO in the brain and peripheral organs.
  • This could lead to a lower usage o f glucose, but the same study admitted an increase glucose usage by the whole brain cell, meaning a differente use of this sugar while the drug is having effects.
  • use of MRI (functional magnetic resounance) showed that the decresed blood flow associate with decreasing in neural activity. A simple explanation for this unexpected situation could be the serotoning agonist action of psilocybin, action that seems to be focused more on 5-HT receptors than on 5-HT2A.
  • psilocibyn is able to act as a 5-HT agonist binding directly its receptors.
  • augmented glucose consumption in several brain regions; this lead to the conclusion that psilocybin is some way able to modify the physiological glucosal metabolic rate of our body
  • The strong inibition of the PCC is now thought to be most significant action of psilocybin on neural disaccoppiation
    • Kenuvis Romero
       
      Lower brain glucose metabolism is linked with increased capacity for working memory.
  • Psilocybin comprises approximately 1% of the weight of Psilocybe cubensis mushrooms, and so nearly 1.7 kilograms (3.7 lb) of dried mushrooms, or 17 kilograms (37 lb) of fresh mushrooms, would be required for a 60-kilogram (130 lb) person to reach the 280 mg/kg LD50 value.
  • psilocybin can cause anxiety and increased heart rate and BP which is very counter- productive for someone on metoprolol and micardis.
  • propose the possibility to use psilocybin as a palliative therapy for terminal illness like cancer but also as a real antidepressive active principle available for the family of the patient. The rational is foundable in the fact that we usually administer SSRI as antidepressive agents, so psilocibyn sholud be useful in this purpose for its selective agonist action on 5-HT2A receptors

New Discoveries on Optimizing Memory Formation | Psychology Today - 2 views

  • In summary, memory optimization would seem to require one to:Create associations that can serve as memory cues.Place a high value on the cues and their targets.Repeatedly present the cues and replay the initial information. When awake, present the cues in self-test mode. When asleep, even better results would obtain if cues were presented at a level that does not cause awakening during the early night sleep when sleep is deepest and there is little dreaming.

Method of loci - Wikipedia, the free encyclopedia - 0 views

  • The Method of Loci (plural of Latin locus for place or location), also called the memory palace, is a mnemonic device introduced in ancient Roman and Greek rhetorical treatises (in the anonymous Rhetorica ad Herennium, Cicero's De Oratore, and Quintilian's Institutio oratoria). The items to be remembered in this mnemonic system are mentally associated with specific physical locations.[1] It relies on memorized spatial relationships to establish, order and recollect memorial content. The term is most often found in specialised works on psychology, neurobiology and memory, though it was used in the same general way at least as early as the first half of the nineteenth century in works on rhetoric, logic and philosophy.[2]

Memory - Wikipedia, the free encyclopedia - 0 views

  • 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]
