-
Dendrimers are well-defined, versatile polymeric architecture with properties resembling biomolecules. Dendritic polymers emerged as outstanding carrier in modern medicine system because of its derivatisable branched architecture and flexibility in modifying it in numerous ways. Dendritic scaffold has been found to be suitable carrier for a variety of drugs including anticancer, anti-viral, anti-bacterial, antitubercular etc., with capacity to improve solubility and bioavailability of poorly soluble drugs. In spite of extensive applicability in pharmaceutical field, the use of dendrimers in biological system is constrained because of inherent toxicity associated with them. This toxicity is attributed to the interaction of surface cationic charge of dendrimers with negatively charged biological membranes in vivo. Interaction of dendrimers with biological membranes results in membrane disruption via nanohole formation, membrane thinning and erosion.
SIRS: Making Students Literate in Digital Age - 70 views

The American Library Association encourages schools and libraries to think twice before keeping kids off social media, saying such prohibition "does not teach safe behavior and leaves youth without the necessary knowledge and skills to protect their privacy or engage in responsible speech." Their policy statement on the topic says that instead of restricting access, librarians and teachers "should educate minors to participate responsibly, ethically and safely."
-
Perhaps the biggest objection to widespread use of social sites is the likelihood that kids will encounter irrelevant or even offensive material--a fear that many teachers say is overblown. While the Web can seem like "a sea of pornography and idiots," says James Lerman, the author of several books on educational technology, schools must help students figure out how to navigate it so they "can get to the good stuff" that's applicable to school.

INTERNSHIP RESPONSIBILITIES: Service hours - 70 hours of community outreach (spread throughout the semester in which you are enrolled in the course)
Study: Effective School Libraries Impact Entire Schools, Not Just Test Scores - 89 views
-
Researchers note that effective school libraries reflect strong cooperation, collaboration, and communication among classroom teachers, administrators and school librarians.
-
Massey notes that most administrators don't know what an effective school library program looks like, and therefore don't understand how they can improve academic achievement.
-
"An effective school library impacts more than student achievement-it also lifts a school's entire educational climate, says a recent two-phase study by Rutgers University's Center for International Scholarship in School Libraries (CISSL) on behalf of the New Jersey Association of School Librarians (NJASL)."

Attention, college shoppers. These schools are slashing their prices. - The Washington Post - 15 views
-
As soaring tuition scares off many families, a growing number of private colleges have embraced a marketing tactic associated more with selling airline tickets or flat-screen televisions than higher education: a price cut. St. John's College slashed tuition from $52,734 in this school year to $35,000 in the next.

Surveys and consumer reports also suggest that the sensory experiences typically associated with reading—especially tactile experiences—matter to people more than one might assume.

Intellectual curiosity and confidence help children take on maths and reading - 2 views
-
"Children's personalities may influence how they perform in maths and reading, according to a study by psychology researchers at The University of Texas at Austin. Proficiency in reading and maths is associated with a complex system of skills, some of which derive from personality traits. In a study published in the Journal of Personality and Social Psychology, researchers found that characteristics related to openness, such as intellectual curiosity and confidence, made children more adept to take on maths and reading than characteristics describing conscientiousness, such as diligence and perseverance."

10 Things To Make Staff Meetings More Productive - 25 views
-
"Drawing from almost 200 scientific studies on workplace meetings, a team of psychological scientists provides recommendations for making the most out of meetings before they start, as they're happening, and after they've concluded. Their report is published in Current Directions in Psychological Science, a journal of the Association for Psychological Science. Meetings are a near-ubiquitous aspect of today's professional workplace and there is abundant trade wisdom and written guidance about how meetings should be run. But, as researchers Joseph Mroz and Joseph Allen (University of Nebraska Omaha) and Dana Verhoeven and Marissa Shuffler (Clemson University) point out, very little of this guidance is informed by the available science."
Teen girls more vulnerable to bullying than boys - 5 views
-
"Girls are more often bullied than boys and are more likely to consider, plan, or attempt suicide, according to research led by a Rutgers University-Camden nursing scholar. "Bullying is significantly associated with depressive symptoms, suicidal ideation, suicide planning, and suicide attempts," says Nancy Pontes, an assistant professor at the Rutgers School of Nursing-Camden. "We wanted to look at this link between bullying victimization, depressive symptoms, and suicidality by gender." In an examination of data from the Centers for Disease Control's nationally representative Youth Risk Behavior Survey from 2011-2015, Pontes and her fellow researchers conducted analyses of the data and found that more females are negatively affected by bullying."
Research: Teens who were severely bullied as children at higher risk of suicidal thoughts, mental health issue - 3 views
-
"Teens who were severely bullied as children by peers are at higher risk of mental health issues, including suicidal thoughts and behaviours, according to new research in CMAJ(Canadian Medical Association Journal). "Our findings showed a general tendency, in about 15% of the children, of being exposed to the most severe levels of victimization from the beginning of their education until the transition to high school," writes Dr. Marie-Claude Geoffroy, McGill Group for Suicide Studies, McGill University, Montréal, Quebec, with coauthors. "Those children were at greater risk of debilitating depressive/dysthymic symptoms or anxiety and of suicidality in adolescence than less severely victimised children, even after we accounted for a plethora of confounders assessed throughout childhood.""
