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.

Precompetitive appraisal, performance anxiety and confidence in conservatorium musician... - 0 views

  • Primary and secondary appraisals formed theoretically consistent and reliable evaluations of threat and challenge. Secondary appraisals were significantly lower for students who viewed the performance as a threat. Students who viewed the performance as a challenge reported significantly less cognitive anxiety and higher self-confidence. Findings indicate that the PAM is a brief and reliable measure of cognitive appraisals that trigger precompetitive emotions of anxiety and confidence which can be used to identify those performers who could benefit from pre-performance intervention strategies to manage performance stress.
  • Music performance anxiety (MPA) can be controlled when musicians cognitively restructure their own thoughts and feelings about their performance by anticipating symptoms of anxiety and turning them to constructive use

  • and substantially determines if performers will suffer emotion-related detriments or profit from emotion-related benefits
  • Emotions that are too weak or intense and feel unpleasant lead to lower motivation, distracted attention, and reduced performance.
  • On the other hand, appropriately intense emotions which feel pleasant and are expected to help future performance are more likely to lead to increased effort, better decision making, and hence enhanced performance
  • Mann-Whitney U tests of mean ranks showed that compared to students who viewed performance as a threat (MThreat = 7.00, SDThreat = 0.99), students who viewed performance as a challenge (MChallenge = 5.02, SDChallenge = 1.91); reported significantly less cognitive anxiety at pre-recital (U = 21.00, z = -2.167, p = .028) and significantly higher self-confidence both at the start of semester, (MThreat = 4.79, SDThreat = 0.90; MChallenge = 6.42, SDChallenge = 1.08; U = 29.50, z = -3.555, p < .001) and pre-recital (MThreat = 4.45, SDThreat = 0.72; MChallenge = 6.55, SDChallenge = 0.98; U = 2.50, z = -3.104, p < .001, Figure 2).

    Whether you're out sick or have a planned day out of the computer lab, writing sub plans is time consuming and often stressful. Technology teachers have a unique set of challenges to consider when deciding what to leave for a sub. This blog post will hopefully give you some solid ideas and peace of mind for the next time you need to be out. I have this other blog post about Technology Tools for Sub Plans with ideas and tools to help your sub be more comfortable using technology. Today's post is going to assume you have a substitute who is not comfortable using or teaching technology. You can skip right to idea #3 if your substitute cannot use any technology.

BUILDING THE FOUNDATION - A Suggested Progression of Sub-skills to Achieve the Reading ... - 83 views

  •  
    This document is based on an analysis that determined the sub-skills students need to achieve in each of the Foundational Skills (K-5) in the Common Core State Standards (CCSS). It contains five sections, each targeting one grade level in: Print Concepts, Phonological Awareness, Phonics and Word Recognition, and Fluency. It also includes instructional examples aligned to the sub-skills, giving teachers samples of activity types that facilitate acquisition of the sub-skills. Each chart includes up to three grade levels to inform instruction for students who are either struggling and need extra support or intervention, or for students performing above grade-level expectations and require enrichment, to allow a teacher to see which skills should have been mastered in the previous year and what students are preparing for in the upcoming years.

Career and Technical Education: Five Ways That Pay Along the Way to the B.A. - 1 views

  •  
    New report from Center on Education and the Workforce, Georgetown University, September 2012, by Anthony P. Carnevale, Tamara Jayasundera, Andrew R. Hanson - Daniela Fairchild of the Thomas B. Fordham Institute writes in The Education Gadfly Weekly: "At 31 percent, the United States currently ranks second among OECD nations-behind Norway-for the percentage of its workforce with a four-year college education. That's the good news. The bad news is that we rank sixteenth for the percentage of our workforce with a sub-baccalaureate education (think: postsecondary and industry-based certificates, associate's degrees). Yet a swath of jobs in America calls for just that sort of preparation, which often begins in high school. Dubbed "middle jobs" in this report by the Center on Education and the Workforce, these employment opportunities pay at least $35,000 a year and are divided among white- and blue-collar work. Yet they are largely ignored in our era of "college for all." In two parts, this report delineates five major categories of career and technical education (CTE), then lists specific occupations that require this type of education. It's full of facts and figures and an excellent resource for those looking to expand rigorous CTE in the U.S. Most importantly, it presents this imperative: Collect data on students who emerge from these programs. By tracking their job placements and wage earnings, we can begin to rate CTE programs, shutter those that are ineffective, and scale up those that are successful. If CTE is ever to gain traction in the U.S.-and shed the stigma of being low-level voc-tech education for kids who can't quite make it academically-this will be a necessary first step."

    "Mind mapping is a visual form of note taking that offers an overview of a topic and its complex information, allowing students to comprehend, create new ideas and build connections. Through the use of colors, images and words, mind mapping encourages students to begin with a central idea and expand outward to more in-depth sub-topics."

  • Indirect elections are “in use between 1840 and 1872.  Indirect elections enhanced the political power of the hacendados, because voting districts often coincided directly with the boundaries of haciendas.  The first stage of an indirect election, when voters gathered to choose electors, occurred in the cantones, the administrative sub-units of a municipality.  Cantones often were made up of nothing more than one or two haciendas, giving landowners a clear advantage to control the selection of electores.  Above and beyond all other aspects of the electoral system, the oral vote [in use until 1950] insured the predominance of patron-client relations” (pages 65-66).  Describes process for recording oral votes.  “Throughout the nineteenth century, national politics followed to a great extent the rise and fall of alliances between departmental networks.  For instance, in the mid 1840s San Vicente and San Miguel were allied against Sonsonate and San Salvador” (page 163).

Figeac 1938:  “Don Doroteo Vasconcelos se portó a la altura del deber patriótico en el primer período de su Administración, pero cometió un grave e imperdonable error:  permitió que lo reeligieran para un segundo período presidencial.  La Constitución Política entonces vigente, prohibía en su artículo 44 la reelección del presidente de la República, y para dar el paso apuntado se dispuso la reforma [de 9 de marzo de 1849 de la Cámara de Senadores]” (page 171). Leistenschneider 1980:  “En marzo de 1849 la Asamblea Legislativa reforma el Art. 44 de la Constitución Nacional, el cual fijaba el período presidencial para dos años, prohibiendo la reelección; la reforma permite la reelección de Presidente por una sola vez” (page 88).

Put Chromebooks in proper context: This is not a joke - TechRepublic - 83 views

  • The issue, instead, is whether a user's needs can be met with web applications and services.

      With newer web-based applications, this is no longer the case. For example, Wordpress will deliver RSS (replaces listserv), a static front page with organized sub-pages and articles (replaces CMS) and a built-in forum. There's no need to adopt Twitter, which replaces only the listserv.

      I use this often during my PBL activities. As students are researching, they post links to websites that are helpful for others and they post their ideas. At the end of the lesson, we look over the list one last time and make our whole-class decision based on our findings. My 5th graders love it and it has made their problem solving much better since it is based on research and collaboration.
