My final product will be a proposed middle school initiative encompassing thinking skills as the core of differentiated instruction to enhance acceleration of learning for mastery of content for all students
The effect of the Indonesian higher education evaluation system on conference proceedings publications
Indonesia has exhibited a unique pattern of conference proceedings publishing
that was distinct from global and regional norms. Conference proceedings are
now an integral part of the major citation databases, and this study examined
their progressive coverage in the context of academic career advancement and
Indonesian government policy. The results of analyses in Web of Science (WoS),
Scopus and to a lesser extent, Dimensions showed an increase in the proportion
of conference proceedings far in excess of global norms and not seen in any
other South East Asian country. In the conference series containing most
Indonesian proceedings papers, there was a recent increase in representation
from Indonesia and an increase in the proportion of those conferences hosted in
Indonesia. Local policy documents and guidelines from 2012 and 2014 appeared to
encourage academics to increase research outputs in high impact internationally
indexed sources but did not make any distinction between document types. The
conclusion suggests that scholars might have found advantage in advancing
through the hierarchy of academia through publishing conference papers that
were quicker and easier to publish than journal articles. The study is
important to policy makers in the area of research evaluation because it
highlights potential changes in academic publishing behaviour by those being
assessed
Assessing the critical material constraints on low carbon infrastructure transitions
We present an assessment method to analyze whether the disruption in supply of a group of materials endangers the transition to low-carbon infrastructure. We define criticality as the combination of the potential for supply disruption and the exposure of the system of interest to that disruption. Low-carbon energy depends on multiple technologies comprised of a multitude of materials of varying criticality. Our methodology allows us to assess the simultaneous potential for supply disruption of a range of materials. Generating a specific target level of low-carbon energy implies a dynamic roll-out of technology at a specific scale. Our approach is correspondingly dynamic, and monitors the change in criticality during the transition towards a low-carbon energy goal. It is thus not limited to the quantification of criticality of a particular material at a particular point in time. We apply our method to criticality in the proposed UK energy transition as a demonstration, with a focus on neodymium use in electric vehicles. Although we anticipate that the supply disruption of neodymium will decrease, our results show the criticality of low carbon energy generation increases, as a result of increasing exposure to neodymium-reliant technologies. We present a number of potential responses to reduce the criticality through a reduction in supply disruption potential of the exposure of the UK to that disruption
3D printing of cement composites
The aims of this study were to investigate the feasibility of generating 3D structures directly in rapid-hardening Portland cement (RHPC) using 3D Printing (3DP) technology. 3DP is a Additive Layer Manufacturing (ALM) process that generates parts directly from CAD in a layer-wise manner. 3D structures were successfully printed using a polyvinylalcohol: RHPC ratio of 3:97 w/w, with print resolutions of better than 1mm. The test components demonstrated the manufacture of features, including off-axis holes, overhangs / undercuts etc that would not be manufacturable using simple mould tools. Samples hardened by 1 day post-build immersion in water at RT offered Modulus of Rupture (MOR) values of up to 0.8Ā±0.1MPa, and, after 26 days immersion in water at RT, offered MOR values of 2.2Ā±0.2MPa, similar to bassanite-based materials more typically used in 3DP (1-3 MPa). Post-curing by water immersion restructured the structure, removing the layering typical of ALM processes, and infilling porosity
High temperature fiber optic microphone having a pressure-sensing reflective membrane under tensile stress
A fiber optic microphone is provided for measuring fluctuating pressures. An optical fiber probe having at least one transmitting fiber for transmitting light to a pressure-sensing membrane and at least one receiving fiber for receiving light reflected from a stretched membrane is provided. The pressure-sensing membrane may be stretched for high frequency response. Further, a reflecting surface of the pressure-sensing membrane may have dimensions which substantially correspond to dimensions of a cross section of the optical fiber probe. Further, the fiber optic microphone can be made of materials for use in high temperature environments, for example greater than 1000 F. A fiber optic probe is also provided with a backplate for damping membrane motion. The backplate further provides a means for on-line calibration of the microphone
Within-guild dietary discrimination from 3-D textural analysis of tooth microwear in insectivorous mammals
Resource exploitation and competition for food are important selective pressures in animal evolution. A number of recent investigations have focused on linkages between diversification, trophic morphology and diet in bats, partly because their roosting habits mean that for many bat species diet can be quantified relatively easily through faecal analysis. Dietary analysis in mammals is otherwise invasive, complicated, time consuming and expensive. Here we present evidence from insectivorous bats that analysis of three-dimensional (3-D) textures of tooth microwear using International Organization for Standardization (ISO) roughness parameters derived from sub-micron surface data provides an additional, powerful tool for investigation of trophic resource exploitation in mammals. Our approach, like scale-sensitive fractal analysis, offers considerable advantages over twodimensional (2-D) methods of microwear analysis, including improvements in robustness, repeatability and comparability of studies. Our results constitute the first analysis of microwear textures in carnivorous mammals based on ISO roughness parameters. They demonstrate that the method is capable of dietary discrimination, even between cryptic species with subtly different diets within trophic guilds, and even when sample sizes are small. We find significant differences in microwear textures between insectivore species whose diet contains different proportions of āhardā prey (such as beetles) and āsoftā prey (such as moths), and multivariate analyses are able to distinguish between species with different diets based solely on their tooth microwear textures. Our results show that, compared with previous 2-D analyses of microwear in bats, ISO roughness parameters provide a much more sophisticated characterization of the nature of microwear surfaces and can yield more robust and subtle dietary discrimination. ISO-based textural analysis of tooth microwear thus has a useful role to play, complementing existing approaches, in trophic analysis of mammals, both extant and extinct
Thai Adolescents and Social Responsibility: Overcoming Violence in Schools and Creating Peace
There is a need to understand the nature of adolescent violent behavior across cultures as well as to learn more about adolescentās social responsibility toward violence. Purpose: To describe social responsibility of adolescents toward violence and explain the aspects of adolescentās social responsibility in Thailand. Design and Methods: Focus group and qualitative individual interviews (N=18) were conducted with 18 participants, including 10 adolescent students, 4 teachers, and 4 parents, to assess their perceptions and behavior on social responsibility and violent behavior. Thematic analysis was conducted in three phases to code transcribed interview data and identify themes of social responsibility toward violence. Findings: Violence has become recognized globally as a critical social problem that requires vital attention. The present study found that it is valuable that adolescent students could cultivate social responsibility toward violence. In this research, the social responsibility was categorized into 4 aspects: 1) Being influenced by others and feeling out of control; 2) Being frustrated with diffusion of responsibility for promoting non-violence; 3) Not accepting responsibility for escalating behavior; and 4) Seeing the larger picture and developing trust. Conclusions: Adolescentsā social responsibility should be promoted through collaborative social support between home and school. This was accepted among the participants as the way to reach the culturally-valued superior moral rank of social responsibility. The concerted collaboration to attain the highest value of social responsibility has the potential to solve issues of violence and latent violence as well as contribute towards a peaceful society. Key words: adolescence, violence, social responsibility, school mental health promotio
Microwave intermodulation distortion of MgB2 thin films
The two tone intermodulation arising in MgB2 thin films deposited in-situ by
planar magnetron sputtering on sapphire substrates is studied. Samples are
characterised using an open-ended dielectric puck resonator operating at 8.8
GHz. The experimental results show that the third order products increase with
the two-tone input power with a slope ranging between 1.5 and 2.3. The
behaviour can be understood introducing a mechanism of vortex penetration in
grain boundaries as the most plausible source of non linearities in these
films. This assumption is confirmed by the analysis of the field dependence of
the surface resistance, that show a linear behaviour at all temperatures under
test.Comment: 13 pages, 3 figures; to be published in Appl. Phys. Let
