Published: June 2017

The purpose of the study is to examine PechaKucha helps EFL Learners’ to enhance their Public Speaking Performances and to explore useful information regarding the PechaKucha implementation as a learning tool. This study was conducted with sixty students at the University level. They were assigned into two groups randomly as experimental and control. The experimental teaching put into practice PechaKucha in accordance with public speaking activities. Meanwhile, the control group was given conventional speaking lessons only. To assess the performance the initial and post-testing by means of analytic scoring rubrics were used. In addition, a survey questionnaire was administrated to experimental group to examine their attitudes towards using Pecha Kucha in improving public speaking skills. The results showed that themost number of students in the experimental group scored higher points than the control group. It can be concluded that the average performance of experimental group on the speaking public presentation skills posttesting increased in 10% comparing with that of the control group. Questionnaire’s results reported that EFL learners in the experimental group mostly conveyed positive attitudes. This study recommended that EFL students need to be familiarized and trained with the use of PechaKucha technology into their EFL teaching.

Published: June 2017

This paper discussed an initiative implemented for on-campus first-year nursing and midwifery students studying Human Body, which covered core Anatomy and Physiology, at a South Australian university. The initiative implemented was flipping the classroom with the objective of facilitating active learning. Formal lectures were replaced by student-centred activities that encouraged studying the topics before coming to class, discussing their understanding and misconceptions, and determining the new learning that was achieved during class. A post-flip classroom survey was used to gauge the impact of the initiative on students. Of the 532 students enrolled in the science class, 188 students completed the questionnaire for a 35% response rate. The survey queried students’ views about the flipped classroom, their experience/s with the teaching format, the learning that transpired, engagement with content and study materials, what they liked about it, impact on their test scores, and areas to improve the initiative. Findings showed 60% preferred the flipped classroom approach,.Students were actively engaged with and challenged by the content. They actively participated and learned, and found the flipped classroom to be interactive,enjoyable and fun. In fact, 77% of respondents recommended flipped classroom to future students.

Published: June 2017

The implementation of Team-Based Learning (TBL, http://www.teambasedlearning.org) in one-semester undergraduate courses of chemistry offered to first year students is reported. TBL is an active learning instructional strategy heavily relying on small group interaction. Teaching lab classes in a TBL context presented a specific challenge, as decisions were required about their role in the global framework and the possibility of incorporating lab activities as “teamwork”. The design of lab sessions as TBL team application activities is here also illustrated, both for a course of General Chemistry and a course of Organic Chemistry. TBL dramatically improved students class attendance and participation. Its implementation has provided a unique opportunity for the pedagogical development of teaching staff. A moderate number of students reported discomfort with TBL: the requirement of individual preparation before classes and the impact of team participation in the final grade is indeed a new ground for most students, often perceived as a troubling deviation from the common social paradigm of the learning process. The role of the instructor as a facilitator of individual and team work, and the clear explanation of the method are thus of utmost relevance.

Abstract. In this paper, we evaluate the performance of two global horizontal solar irradiance (GHI) estimates, one derived from Meteosat Second Generation (MSG) and another from the 1-day forecast of the Regional Atmospheric Modeling System (RAMS) mesoscale model. The horizontal resolution of the MSG-GHI is 3 × 5 km2 over Italy, which is the focus area of this study. For this paper, RAMS has the horizontal resolution of 4 km.The performances of the MSG-GHI estimate and RAMS-GHI 1-day forecast are evaluated for 1 year (1 June 2013–31 May 2014) against data of 12 ground-based pyranometers over Italy spanning a range of climatic conditions, i.e. from maritime Mediterranean to Alpine climate.Statistics for hourly GHI and daily integrated GHI are presented for the four seasons and the whole year for all the measurement sites. Different sky conditions are considered in the analysisResults for hourly data show an evident dependence on the sky conditions, with the root mean square error (RMSE) increasing from clear to cloudy conditions. The RMSE is substantially higher for Alpine stations in all the seasons, mainly because of the increase of the cloud coverage for these stations, which is not well represented at the satellite and model resolutions. Considering the yearly statistics computed from hourly data for the RAMS model, the RMSE ranges from 152 W m−2 (31 %) obtained for Cozzo Spadaro, a maritime station, to 287 W m−2 (82 %) for Aosta, an Alpine site. Considering the yearly statistics computed from hourly data for MSG-GHI, the minimum RMSE is for Cozzo Spadaro (71 W m−2, 14 %), while the maximum is for Aosta (181 W m−2, 51 %). The mean bias error (MBE) shows the tendency of RAMS to over-forecast the GHI, while no specific behaviour is found for MSG-GHI.Results for daily integrated GHI show a lower RMSE compared to hourly GHI evaluation for both RAMS-GHI 1-day forecast and MSG-GHI estimate. Considering the yearly evaluation, the RMSE of daily integrated GHI is at least 9 % lower (in percentage units, from 31 to 22 % for RAMS in Cozzo Spadaro) than the RMSE computed for hourly data for each station. A partial compensation of underestimation and overestimation of the GHI contributes to the RMSE reduction. Furthermore, a post-processing technique, namely model output statistics (MOS), is applied to improve the GHI forecast at hourly and daily temporal scales. The application of MOS shows an improvement of RAMS-GHI forecast, which depends on the site considered, while the impact of MOS on MSG-GHI RMSE is small.

Published: June 2017

ABSTRACTA simple, versatile, sustainable, not expensive method for the functionalization of sp2 carbon allotropes, both nano-sized and nano-structured, without altering their bulk crystalline organization, is presented. Carbon materials available at the commercial scale were used: furnace carbon black (CB), nano-sized graphite with high surface area, and multiwalled carbon nanotubes. A bio-sourced molecule, 2-(2,5-dimethyl-1H-pyrrol-1-yl)-1,3-propanediol (serinol pyrrole), was used for the functionalization. Serinol pyrrole (SP) was obtained from serinol through a reaction with atomic efficiency of about 82%, performed in the absence of solvents or catalysts. Synthesis of serinol pyrrole was performed as well on carbon allotropes as the solid support. Adducts of serinol pyrrole with a carbon allotrope were prepared with the help of either thermal or mechanical energy. Functionalization yield was in all cases larger than 90%. With such adducts, stable dispersions in water and in NR latex were prepared. A few layers of graphene were isolated from the water dispersions, and NR-based composites precipitated from the latex revealed very even distribution of fine graphitic particles. Composites were prepared, based on NR, IR, and BR as the rubbers and CB and silica as the fillers, with different amounts of CB–SP adduct, and were cross-linked with a sulfur-based system without observing appreciable effect of functionalization on vulcanization kinetics. The CB–SP adduct led to appreciable reduction of the Payne effect.

Published: June 2017

Background:
The experience of psychological distress is prevalent in people with multiple sclerosis (MS), including high levels of stress, anxiety, and depression. It has been shown that people with MS use less adaptive coping compared with healthy individuals. This study examined the ability of coping strategies to predict maladaptive and adaptive psychosocial outcomes across areas of stress, depression, anxiety, and quality of life (QOL) in people with MS.

Methods:
107 people with MS completed measures of depression (Beck Depression Inventory–II), anxiety (State-Trait Anxiety Inventory), QOL (Multiple Sclerosis Quality of Life–54), stress (Daily Hassles Scale), and coping (COPE inventory).

Results:
Consistent with expectations, depression, frequency of stress, trait anxiety, and mental health QOL were predicted by adaptive and maladaptive coping styles. Severity of stressful events was predicted by maladaptive, but not adaptive, coping styles. Depression and mental health QOL were most prominently connected to coping use. Emotional preoccupation and venting showed the strongest relationship with poorer psychosocial outcomes, whereas positive reinterpretation and growth seemed to be most beneficial.

Conclusions:
The results of this study highlight the importance of intervention programs targeting specific coping strategies to enhance psychosocial adjustment for people with MS.

Development of drug resistance limits the effectiveness of anticancer treatments. Understanding the molecular mechanisms triggering this event in tumor cells may lead to improved therapeutic strategies. Here we used RNA-seq to compare the transcriptomes of a murine erythroleukemia cell line (MEL) and a derived cell line with induced resistance to differentiation (MEL-R). RNA-seq analysis identified a total of 596 genes (Benjamini–Hochberg adjustedp-value < 0.05) that were differentially expressed by more than two-fold, of which 81.5% (486/596) of genes were up-regulated in MEL cells and 110 up-regulated in MEL-R cells. These observations revealed that for some genes the relative expression of mRNA amount in the MEL cell line has decreased as the cells acquired the resistant phenotype. Clustering analysis of a group of genes showing the highest differential expression allowed identification of a sub-group among genes up-regulated in MEL cells. These genes are related to the organization of the actin cytoskeleton network. Moreover, the majority of these genes are preferentially expressed in the hematopoietic lineage and at least three of them,Was(Wiskott Aldrich syndrome),Btk(Bruton’s tyrosine kinase) andRac2, when mutated in humans, give rise to severe hematopoietic deficiencies. Among the group of genes that were up-regulated in MEL-R cells, 16% of genes code for histone proteins, both canonical and variants. A potential implication of these results on the blockade of differentiation in resistant cells is discussed.

AbstractDeep tectonic tremor, which is extremely sensitive to small stress variations, could be used to monitor fault zone processes during large earthquake cycles and aseismic processes before large earthquakes. In this study, we develop an algorithm for the automatic detection and location of tectonic tremor beneath the southern Central Range of Taiwan and examine the spatiotemporal relationship between tremor and the 4 March 2010 ML6.4 Jiashian earthquake, located about 20 km from active tremor sources. We find that tremor in this region has a relatively short duration, short recurrence time, and no consistent correlation with surface GPS data. We find a short‐term increase in the tremor rate 19 days before the Jiashian main shock, and around the time when the tremor rate began to rise one GPS station recorded a flip in its direction of motion. We hypothesize that tremor is driven by a slow‐slip event that preceded the occurrence of the shallower Jiashian main shock, even though the inferred slip is too small to be observed by all GPS stations. Our study shows that tectonic tremor may reflect stress variation during the prenucleation process of a nearby earthquake.

Published: June 2017

AbstractWe present a detailed study of the
auroral emission at Jupiter, which uses data taken on 31 December 2012 with the long‐slit echelle spectrometer Cryogenic Infrared Echelle Spectrograph (European Southern Observatory's Very Large Telescope). The entire northern auroral region was observed using significantly more slit positions than previous studies, providing a highly detailed view of ionospheric flows, which were mapped onto polar projections. Previous observations of ionospheric flows in Jupiter's northern auroral ionosphere, using the long‐slit echelle spectrometer CSHELL (NASA Infrared Telescope Facility) to measure the Doppler‐shifted
ν
2 Q(1,0−) line at 3.953 μm, showed a strongly subrotating region that was nearly stationary in the inertial magnetic frame of reference, suggesting an interaction with the solar wind. In this work, we observe this stationary region coincident with a polar region with very weak infrared emission, typically described as the dark region in UV observations. Although our observations cannot determine the exact mechanisms of this coupling, the coincidence between solar wind controlled ionospheric flows and a region with very low auroral brightness may provide new insights into the nature of the solar wind coupling. We also detected a superrotating ionospheric flow measured both at and equatorward of the narrow bright portion of the main auroral emission. The origin of this flow remains uncertain. Additionally, we detect a strong velocity shear poleward of the peak in brightness of the main auroral emission. This is in agreement with past models which predict that conductivity, as well as velocity shear, plays an important role in generating the main auroral emission.
Geographic variations in lowermost mantle structure from the ray parameters and decay constants of core‐diffracted waves
Authors: Euler Garrett G. , Wysession Michael E. 
Published: June 2017

AbstractWe introduce an array‐based approach for constraining seismic velocity structure in the lowermost mantle by measuring the frequency dependence of the ray parameter p and decay constant γ for core‐diffracted waves (Pdiff and SHdiff). The approach uses an iterative multichannel cross‐correlation algorithm that solves for relative arrival times and amplitudes of core‐diffracted waveforms from multiple peaks in normalized correlograms from pairs of coazimuthal stations. The approach is applied to 60 mb ≥ 5.8 earthquakes for Pdiff and 36 for SHdiff during 2001–2002, with nearly 50,000 unique profile station pairs with epicentral‐distance differences of Δd ≥ 10° and azimuth differences of Δφ ≤ 10°, sampling a significant portion of the lowermost mantle. Cap‐averaging the resulting ray parameter estimates produces geographic variations that are largely consistent with the distribution of lowermost mantle large low‐velocity provinces and seismically fast slab‐accumulation regions seen in seismic tomography models, whose locations also strongly influence the geographic distribution of heat flow out of the core. Geographic variations in station‐pair diffracted‐wave decay constants differ from those of the ray parameters, suggesting that variations in the decay of core‐diffracted waves are more linked to lowermost mantle seismic velocity gradients than absolute values of seismic velocity. The ray parameters and decay constants of core‐diffracted waves are strongly frequency‐dependent, and these frequency variations also vary significantly with geographic location. Combining lateral and vertical seismic‐velocity variations with mineral‐physics data on elasticity and conductivity of lowermost mantle species can provide constraints on D″ composition and CMB heat flux.
Intercultural Communication Study in China
Authors: Chen Ling 
Published: June 2017

Abstract
Intercultural communication studies as an academic study area in China has mushroomed in recent decades, first taken up—and still mainly led—by scholars in English as a foreign language education, with important contributions from communication scholars. The scholarship is generally represented in continuous discussion on the conceptual front with broadening appreciation of this topic area to consider all its complexity, while data‐based research is still in its infancy. Major research topics have largely concentrated on language‐related communication aspects, from cultural influence on language learners to language use in numerous situations to reproduce culture and affect intercultural communication. Emerging topics reflect efforts to more directly connect China and global contexts in intercultural communication study.
Individualism and Collectivism
Authors: Bhawuk Dharm P. S. 
Published: June 2017

Abstract
The constructs of individualism and collectivism have been used in the social sciences from the beginning of research. However, the constructs gained popularity in the 1980s, and they continue to draw the attention of social scientists in all disciplines even today. A theoretical framework using the independent and interdependent concepts of selves at its core is presented to explain the differences between these constructs. Because of differences in concepts of selves, people treat their ingroup and outgroup differently; they act differently in the society by following their attitude or conforming to social norms; and they engage in a different pattern of social exchange with other individuals. The entry discusses these differences and their implications for intercultural communication.

Published: June 2017

Abstract2‐Arylcyclopropandicarboxylate werden mit Naphthochinonen zur Reaktion gebracht. Der Schlüsselschritt besteht in der Verwendung von katalytischen Mengen an SnCl2, das sowohl als Elektronendonor als auch als Lewis‐Säure fungiert. Mittels einer In‐situ‐Umpolung wird das vormals elektrophile Naphthochinon in ein Nukleophil überführt. Dieses löst die Ringöffnung des Dreirings aus, wobei eine neue C‐C‐Bindung geknüpft wird. Werden die so erhaltenen Produkte mit einer Base unter oxidativen Bindungen umgesetzt, führt dies – durch Abspaltung von Methylformiat – zu cyclopentanellierten Produkten mit einem komplett konjugierten π‐System, welche eine intensive Absorption im sichtbaren Bereich aufweisen.

AbstractReactions of 2‐arylcyclopropane dicarboxylates with naphthoquinones are reported. The key feature was the use of catalytic amounts of SnCl2, which acts as both an electron donor and a Lewis acid. By an in situ umpolung of naphthoquinone the formerly electrophilic species is converted into a nucleophile that is able to trigger the ring‐opening of the three‐membered ring with formation of a new C−C bond. Treatment of these products with base under oxidative conditions resulted—through loss of methyl formate—in cyclopentannulated products with fully conjugated π systems exhibiting intensive absorptions in the visible range.

AbstractTwo simple colorimetric receptors PS and PP (thiophene and pyridine appended derivative) were prepared and their cation sensing properties were investigated. Receptors PS and PP displayed a selective colorimetric change (from colorless to orange) upon binding to Fe3+ in MeOH solution. The association constants for receptors PS–Fe3+ and PP–Fe3+ in MeOH were determined to be 1.15 × 106 and 4.31 × 106 M−1, respectively, using Hill plots. The detection limits of PS and PP were 490.7 ppm and 393.7 ppm, respectively.

Published: June 2017

AbstractA new redox‐active 4,5‐bisguanidino‐substituted o‐benzoquinone ligand L is synthesized, which allows rational access to heterobinuclear complexes through the sequential coordination of two metals. In the examples discussed in this work, mononuclear Cu and Pd complexes are prepared in a first coordination step, and these complexes are then used as precursors to homobinuclear [CuII‐L0‐CuII] and heterobinuclear [PdII‐L0‐CuII] complexes. In the heterobinuclear complex, the PdII is coordinated by the softer bisguanidine side of L and the CuII by the harder dioxolene side (in line with the HSAB concept). The heterobinuclear complex is in a temperature‐dependent equilibrium with its dimer, with two unsymmetrical Cu‐Cl‐Cu bridges. The redox‐chemistry of the [CuII‐L‐CuII] and [PdII‐L‐CuII] complexes is studied. One‐electron oxidation of both complexes was found to be quasi‐reversible in CV experiments, and chemical one‐electron oxidation was achieved with NO+(SbF6−). In the case of the homobinuclear complex [L(CuCl2)2]+, intramolecular ligand–metal electron‐transfer, triggered by coordination of a CH3CN solvent molecule, leads to a temperature‐dependent equilibrium between the form [CuII‐L0‐CuIII] at low temperatures (with CH3CN coordinated to the CuIII atom) and [CuII‐L⋅+‐CuII] at higher temperatures (without CH3CN).
