    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.

      Pro - Argument #1
  • 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.

    Understanding and applying technologies to the teaching of writing - as well as understanding concepts associated with them such as copyright and fair use - has become the professionally responsible way to teach writing . Professional organizations such as NCTE NWP IRA ISTE the Center for Media Literacy and others have moved quickly and clearly in the past few years to show that integrating technology across content areas, including the teaching of writing, is critical for creating students who are literate in a variety of ways.

  • AssessmentThere were four components of the assessment process for this test case of the Networked Student Model: (1) Ongoing performance assessment in the form of weekly assignments to facilitate the construction and maintenance of the personal learning environment, (2) rubric-based assessment of the personal learning environment at the end of the project, (3) written essay, and (4) multimedia synthesis of topic content. Points were earned for meeting the following requirements: Identify ten reliable resources and post to social bookmarking account. At least three new resources should be added each week. Subscribe and respond to at least 3 new blogs each week. Follow these blogs and news alerts using the reader. Subscribe to and listen to at least two podcasts (if available). Respectfully contact and request a video conference from a subject matter expert recognised in the field. Maintain daily notes and highlight resources as needed in digital notebook. Post at least a one-paragraph reflection in personal blog each day. At the end of the project, the personal learning environment was assessed with a rubric that encompassed each of the items listed above. The student's ability to synthesise the research was further evaluated with a reflective essay. Writing shapes thinking (Langer & Applebee, 1987), and the essay requirement was one more avenue through which the students demonstrated higher order learning. The personal blog provided an opportunity for regular reflection during the course of the project. The essay was the culmination of the reflections along with a thoughtful synthesis of the learning experience. Students were instructed to articulate what was learned about the selected topic and why others should care or be concerned. The essay provided an overview of everything learned about the contemporary issue. It was well organised, detailed, and long enough to serve as a resource for others who wished to learn from the work. As part of a final exam, the students were required to access the final projects of their classmates and reflect on what they learned from this exposure. The purpose of this activity was to give the students an additional opportunity to share and learn from each other. Creativity is considered a key 21st century skill (Partnership for 21st Century Skills, 2009). A number of emerging web applications support the academic creative process. Students in this project used web tools to combine text, video, audio, and photographs to teach the research topics to others. The final multimedia project was posted or embedded on the student's personal wiki page. Analysis and assessment of student work was facilitated by the very technologies in use by the students. In order to follow their progress, the teacher simply subscribed to student social bookmarking accounts, readers, and blogs. Clicking through daily contributions was relatively quick and efficient.

    COURSE OBJECTIVES: This is a graded internship that allows you to integrate your own coursework with a hands-on service learning experience. The central objective of this course is to provide students with community experiences and reflection opportunities that examine community needs, the importance of civic engagement, and social justice issues affecting ethnic minorities and marginalized populations in contemporary American society. Students dedicate 70 hours at a pre-approved site (including Title I K-12 schools, youth programs, health services, social services, environmental programs, government agencies, etc.) directly serving a population in need or supporting activities that contribute to the greater good of our community. A weekly seminar, course readings, discussions, and reflection assignments facilitate critical thinking and a deeper understanding of cultural diversity, citizenship, and how to contribute to positive social change in our community. The course is also designed to provide "real-world" experiences that exercise academic skills and knowledge applicable to each student‟s program of study and career exploration. STUDENT LEARNING OBJECTIVES: Student will be introduced to essential skills associated with their baccalaureate studies to actively serve the local community. While completing this in-depth study of cultural diversity, citizenship and social justice issues facing our community, students will gain an understanding of the value of Social Embeddedness and the importance of incorporating civic engagement into their collegiate careers, as they strive to become civically engaged students. Students will be introduced to inequalities, discrimination, and other community issues facing ethnic minorities and marginalized populations, as well as the correlation with greater societal issues. INTERNSHIP RESPONSIBILITIES:  Service hours - 70 hours of community outreach (spread throughout the semester in which you are enrolled in the course)

  • 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.
  • Roland Gesthuizen on 26 Apr 12
     
    "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)."

St. John's College slashed tuition from $52,734 in this school year to $35,000 in the next.

  • Although many old and recent studies conclude that people understand what they read on paper more thoroughly than what they read on screens, the differences are often small. Some experiments, however, suggest that researchers should look not just at immediate reading comprehension, but also at long-term memory.
  • When taking the quiz, volunteers who had read study material on a monitor relied much more on remembering than on knowing, whereas students who read on paper depended equally on remembering and knowing.
  • E-ink is easy on the eyes because it reflects ambient light just like a paper book, but computer screens, smartphones and tablets like the iPad shine light directly into people's faces.

  • People who took the test on a computer scored lower and reported higher levels of stress and tiredness than people who completed it on paper.
  • Although people in both groups performed equally well on the READ test, those who had to scroll through the continuous text did not do as well on the attention and working-memory tests.
  • Subconsciously, many people may think of reading on a computer or tablet as a less serious affair than reading on paper. Based on a detailed 2005 survey of 113 people in northern California, Ziming Liu of San Jose State University concluded that people reading on screens take a lot of shortcuts—they spend more time browsing, scanning and hunting for keywords compared with people reading on paper, and are more likely to read a document once, and only once.

    "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."

    "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."

    "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."

    "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.""
