The goals of this study were (1) determine the prevalence of various features of representations in five general chemistry textbooks used in the United States, and (2) use cognitive load theory to draw implications of the various features of analyzed representations. We adapted the Graphical Analysis Protocol (GAP) (Slough et al., 2010) to look at the type of representations used, the function of each representation, the physical integration of representations with associated text, the presence and nature of captions and labels, the indexing of representations, and the number of representations requiring conceptual integration on a given page. Results indicate that on average, in all five textbooks each page had at least four representations. Most representations served a 'representational' function, but a number functioned as decorative representations. Most representations were directly integrated with text, but some of the remaining representations were separated by a whole page from associated text. While many pages had an average of two representations that required conceptual integration with text or other representations, some pages had as many as six representations requiring integration. While using textbooks, learners can experience intrinsic, germane or extraneous cognitive load (Sweller, 1994). Our findings indicate that there are various features of representations that could help reduce intrinsic or extraneous cognitive load. However, we also found prevalent features of representations that imply high intrinsic cognitive load or are likely to lead to extraneous cognitive load. Implications for textbook authors and editors, textbook selection, instruction, and science teacher preparation are discussed. © 2017 The Royal Society of Chemistry.

Ligand-capped metal entities come in two sizes, (1) molecular clusters of 10-200 metal atoms and (2) nanoparticles of 2000-10000 metal atoms. In numerous cases, certain magic sizes have been found to be most accessible and stable, clusters of 25, 38, 55, and 102 atoms and nanoparticles of 3500-5000 atoms or 4-5 nm. The most familiar and studied system is that of gold (metal) and thiol (ligand). Herein, the methods of synthesis of these gold clusters versus gold nanoparticles are carefully compared. In the cluster case, an important intermediate is the (Au +SR -) n polymer, which is not the case in the synthesis of nanoparticles either from metal (vapor) atoms or metal ions. Also, it is shown that thiol can act as both a reductant (Au 3+ → Au +) and as an oxidant (Au 0 → Au +). The thermodynamic forces responsible for the favored formation of certain size clusters and nanoparticles are discussed. © 2012 American Chemical Society.

The current study examined female bloggers' perceptions of online and "real-life" same-sex friendships and examined relationships between self-disclosure through blogs and perceptions of the two types of friendships. Three hundred seven female bloggers (M age34.56 years) completed an online survey regarding friendship satisfaction and perceptions of intimacy-promoting interaction patterns in friendships. One hundred respondents' weblogs were analyzed for self-disclosure. Self-reported self-disclosure was positively correlated with number of online friendships and satisfaction with online friendships. Although participants reported having close online friends, they perceived real-life friendships as more likely than online friendships to possess intimacy-promoting interaction patterns. These perceptions did not differ as a function of self-disclosure through blogging, although bloggers who were categorized as higher in disclosure were more satisfied with online friendships than were bloggers who were categorized as lower in disclosure. These results suggest a relationship between self-disclosure through blogging and online relationship satisfaction among women in middle adulthood but that these women perceive real-life friendships as more likely to offer interaction patterns that foster intimacy. © Mary Ann Liebert, Inc. 2010.

Forms of homeostatic plasticity stabilize neuronal outputs and promote physiologically favorable synapse function. A well-studied homeostatic system operates at the Drosophila melanogaster larval neuromuscular junction (NMJ). At the NMJ, impairment of postsynaptic glutamate receptor activity is offset by a compensatory increase in presynaptic neurotransmitter release. We aim to elucidate how this process operates on a molecular level and is preserved throughout development. In this study, we identified a tyrosine kinase-driven signaling system that sustains homeostatic control of NMJ function. We identified C-terminal Src Kinase (Csk) as a potential regulator of synaptic homeostasis through an RNAi- and electrophysiology-based genetic screen. We found that Csk loss-of-function mutations impaired the sustained expression of homeostatic plasticity at the NMJ, without drastically altering synapse growth or baseline neurotransmission. Muscle-specific overexpression of Src Family Kinase (SFK) substrates that are negatively regulated by Csk also impaired NMJ homeostasis. Surprisingly, we found that transgenic Csk-YFP can support homeostatic plasticity at the NMJ when expressed either in the muscle or in the nerve. However, only muscle-expressed Csk-YFP was able to localize to NMJ structures. By immunostaining, we found that Csk mutant NMJs had dysregulated expression of the Neural Cell Adhesion Molecule homolog Fasciclin II (FasII). By immunoblotting, we found that levels of a specific isoform of FasII were decreased in homeostatically challenged GluRIIA mutant animals–but markedly increased in Csk mutant animals. Additionally, we found that postsynaptic overexpression of FasII from its endogenous locus was sufficient to impair synaptic homeostasis, and genetically reducing FasII levels in Csk mutants fully restored synaptic homeostasis. Based on these data, we propose that Csk and its SFK substrates impinge upon homeostatic control of NMJ function by regulating downstream expression or localization of FasII. © 2016 Spring et al.

We observed 42 molecular condensations within previously identified bright-rimmed clouds in the ammonia rotational inversion lines NH3(1,1), (2,2), (3,3) and (4,4) using the Green Bank Telescope in Green Bank, West Virginia. Using the relative peaks of the ammonia lines and their hyperfine satellites we have determined important parameters of these clouds, including rotational temperatures and column densities.These observations confirm the presence of dense gas towards IRAS point sources detected at submillimetre wavelengths. Derived physical properties allow us to refine the sample of bright-rimmed clouds into those likely to be sites of star formation, triggered via the process of radiatively driven implosion. An investigation of the physical properties of our sources shows that triggered sources are host to greater turbulent velocity dispersions, likely indicative of shock motions within the cloud material. These may be attributed to the passage of triggered shocks or simply the association of outflow activity with the sources.In all, we have refined the Sugitani, Fukui and Ogura catalogue to 15 clouds which are clearly star-forming and influenced by external photoionization-induced shocks. These sources may be said, with high confidence, to represent the best examples of triggering within bright-rimmed clouds. © 2010 The Authors. Journal compilation © 2010 RAS.


In the latter part of the nineteenth century, venereal diseases were seen not only as a problem in Germany, but also in its colonial empire. In Germany, doctors believed that through their scientific training and education they could be successful in fighting VD through the use of a biopolitics aimed to educate and regulate the bodies of targeted groups. They approached the problem in the colonies from a similar perspective. However, the colonial setting was different from the homeland, which meant that policies pursued in Germany had to be modified overseas. In the end, they achieved a greater degree of supervision over targeted bodies than their peers at home. Accordingly, the goal of subjectifcation, though not entirely abandoned, assumed secondary importance behind the perceived need for more coercive methods. © 2013 The Author 2013.

Gold-acetone-dodecanethiol and gold-acetone-phenylethanethiol colloids were prepared by the solvated metal atom dispersion method. Hydrogen evolution occurred at fairly low temperature, when the melting acetone-gold solvate encountered the thiol molecules, due to S-H bond scission. The gas inside the reactor was analyzed by gas chromatography, and the moles of H 2 was determined by calibration curves obtained from a series of known concentration samples. The gold-to-thiolate ratio was calculated using thermal gravimetric analysis. The average particle diameter was also calculated using the gold-to-thiolate ratio. © 2012 American Chemical Society.

Magneto-rheological elastomers (MREs) are a class of soft active materials known for their tunable stiffness. Dispersed with magnetic particles, these polymer-based composites tend to be stiffer under a magnetic field. Such a stiffening effect is often attributed to the magnetic interaction among filler particles, but the well-acknowledged dipole-interaction model fails to explain the stiffening effect in tension/compression, which was observed in experiments. Other mechanisms, such as the effect of non-affine deformation, have been proposed, but there is no conclusive evidence on the dominating mechanism for the field-stiffening effect. This paper investigates various filler-chain structures, and seeks to identify the ultimate origin of the field-stiffening effect in MREs. Two different methods are used for cross verification: a dipole-interaction model and a finite-element simulation based on continuum field theories. This paper studies both the shear and axial deformation of the material, with a magnetic field applied in the particle-chain direction. It is found that while the magnetic interaction between particles is indeed the major cause of the stiffening effect, the wavy chain structure is the key to the modulus increase. Besides, chain-chain interaction and non-affine deformation are shown to be insignificant. In addition, the dependence of the stiffening effect on filler concentration is calculated, and the results qualitatively agree with experimental observations. The models also predict some interesting results that could be easily verified by future experiments. © 2013 Elsevier Ltd. All rights reserved.

The goal of this S-STEM project is to guide high-achieving STEM students in becoming academically and civically-engaged scientists (ACES). The underlying premise of this proposal is that as the US increases the number of STEM professionals in order to excel in innovation, it is equally important that those STEM professionals see their chosen vocations as giving them a responsibility to serve their community, nation, and world as citizens. The ACES program will support a diverse cohort of 10-11 STEM students who will be awarded scholarships each year. As freshmen, scholars live in a residential cluster, enroll in common courses together, and explore what it means to be civically-minded scholars. As seniors, scholars complete an individualized honors research project with a faculty member. Each ACES cohort completes community engagement projects every year that allow them to apply their STEM knowledge and their leadership skills. They will also participate in mentoring programs and career development opportunities.

The specific measurable objectives of this project are to: (1) recruit diverse students to STEM fields, (2) retain 85% of scholarship recipients in a STEM field, (3) increase civic mindedness and engagement among participants, and (4) achieve a STEM placement for 90% of the program graduates. The ACES program will enable scholars to develop professional relationships with their peers and community partners, and articulate what it means to be a civically-engaged scientist to a variety of audiences. As a result of this program, ACES students will be able to actively engage with community issues by applying their scientific body of knowledge and skills. Assessment and evaluation of the ACES program will contain both formative and summative components using both direct and indirect evidence-based measures.
