Online Learning Environments, Scientific Argumentation, and 21st Century Skills

2019

A workshop held at the National Academies in the United States in 2007 highlighted five broad categories of skills that appear valuable across a range of jobs for people working in modern global economies. Engaging students in scientific argumentation can support the development of these 21st century skills. Unfortunately, opportunities are rare in typical classrooms for students to learn how to engage in scientific argumentation. Over the past ten years several online environments have been developed to support students engaging with one another in scientific argumentation. This paper considers how engaging students in scientific argumentation through the activity structures and scripts in…

An experimental search for a correlation between outdoor 222Rn concentration and 210Pb activity in air particulate samples

2018

This work was aimed to search for a correlation between outdoor 222Rn air concentration and 210Pb activity in particulate samples collected on a filter. The existence of a correlation could support the hypothesis that both 222Rn and its long-lived product 210Pb are embedded into the same air masses and undergo the same air transport phenomena. Lead-210 activity was determined by means of gamma ray spectrometric measurement carried out a few days after the sampling whereas 222Rn concentration was measured through a commercial monitor. Experimental tests allowed to obtain a weak correlation between 222Rn and 210Pb air concentration as a preliminary result due to high uncertainties of outdoor …

Gold nanostar–polymer hybrids for siRNA delivery: Polymer design towards colloidal stability and in vitro studies on breast cancer cells

2017

To overcome the low bioavailability of siRNA (small interfering RNA) and to improve their transfection efficiency, the use of non-viral delivery carriers is today a feasible approach to transform the discovery of these incredibly potent and versatile drugs into clinical practice. Polymer-modified gold nanoconstructs (AuNCs) are currently viewed as efficient and safe intracellular delivery carriers for siRNA, as they have the possibility to conjugate the ability to stably entrap and deliver siRNAs inside cells with the advantages of gold nanoparticles, which can act as theranostic agents and radiotherapy enhancers through laser-induced hyperthermia. In this study, AuNCs were prepared by coat…
