Pedagogy and content evolution in cross-border higher education: Evidence from an American-Singaporean cross-border partnership
Authors: Fisher Dara R 
Published: June 2017

Reflecting larger trends in business, economics, and communications, the field of higher education has undergone a rapid period of globalization and internationalization over the last half century. While much scholarship has been devoted to the policies and practices of cross-border higher education work, little research has examined the mechanisms by which educational practices and approaches are modified and adapted when moved across cultural contexts. This paper addresses this gap by examining the processes by which foreign and local partners adapted and modified American educational approaches to fit the needs of Singaporean students in a large-scale cross-border higher education partnership. Developed based on a year of immersive ethnographic fieldwork at the Singapore University of Technology and Design – a new university established in collaboration with the Massachusetts Institute of Technology – the findings of this paper show that local and foreign partners utilized three distinct strategies to modify American pedagogical and curricular approaches to fit the needs of the Singaporean context: collaborative mentorship and guidance, incremental modification of content and practice, and enabling and facilitating student-driven change. This paper presents an overview of these findings, as well as their implications for future work.
Examining Preservice Teachers’ Self-Efficacy for Enhancing Literacy of Diverse Learners through Music
Authors: Arrington Nancy McBride 
Published: June 2017

The sense of efficaciousness for teaching diverse learners was examined with twenty-four pre-service teachers concurrently enrolled in a junior-level Creative Arts methods course and a field experience course with placements in K-2 general education classrooms. The pre-service teachers participated in music and literacy activities in their university class, then planned and implemented standards-based music activities in literacy lessons with their young students. Both quantitative and qualitative data were collected, including a teacher self-efficacy scale, an attitude survey, written reflections, interviews, open-ended responses, and lesson plans. Results demonstrated a significant increase in the pre-service teachers’ self-efficacy in pre-post ratings analysis and indicated that this project contributed to their efficacy for meeting needs of diverse learners in the elementary classrooms. The pre-service teachers demonstrated proactive classroom management and reflected upon their students’ increased focus in class. The pre-service teachers indicated that their success with these types of projects encouraged them to plan for similar implementation with their future diverse learners, potentially contributing to a positive impact on their future performance. Additionally, this project emanated Scholarship of Teaching and Learning by encouraging self-reflection; examining and applying effective teaching strategies; and advancing the field of teacher education.

Automated Program Analysis for Novice Programmers
Authors: Fehnker Ansgar , Blok Tim 
Published: June 2017

This paper describes how to adapt a static code analyzer to provide feedback novice programmers and their teachers. Current analyzers have been built to give feedback to experienced programmers who work on software projects or systems. The type of feedback and the type of analysis of these tools focusses on mistakes that are relevant within that context, and help with debugging software system. When teaching novice programmers this type of advice is often not particularly useful. It would be instead more useful to use these techniques to identify problem in the understanding of students of important programming concepts. This paper first explores in what respect static analyzers support the learning and teaching of programming, and what can be implemented based on existing static analysis technology. It presents an extension of static analyzer PMD to create feedback that is more valuable to novice programmers. To answer the question if these techniques are able to find conceptual mistakes that are characteristic for novice programmers make, we ran it over a number of student projects, and compared these results with publicly available mature software projects.
Promoting Innovation and Creativity in Initial Teacher Technical Education in Ireland: A Case Study
Authors: Logue Pauline Anne 
Published: June 2017

The Galway-Mayo Institute of Technology (GMIT), Ireland, is a Higher Education (HE) provider of Initial Teacher Education (ITE).Graduates on its BSc (Hons) in Education (Design, Graphics and Construction) degree programme are qualified to teach technical subjects at second level. A defining element of delivery is the promotion of creativity and innovation in the classroom, by means of active, student-centred and design-led teaching and learning (T&amp;L) strategies. This paper outlines a GMIT qualitative student-perspective pilot study, involving a total of 42 GMIT student teacher participants (n=42). The study aims to analyse the effectiveness of two selected platforms in the ITE programme: 1) presentation contributions by 14 student teachers at the GMIT ‘Creativity and Innovation in Teaching’ Conference (2016) (n=14), and 2) a textual analysis of student online forum critical reflection submissions (2016-2017) (n=28). The research confirms the effectiveness of both strategies in promoting a practice of innovation and creativity in the classroom, including evidence of the innovative educational technology classroom tools and increased student-centred, active learning and design-led strategies in T&amp;L. Keywords: Creativity, Innovation, Educational Technology, Technical Education, Initial Teacher Education, Active teaching Strategies.
Wind-driven snow conditions control the occurrence of contemporary marginal mountain permafrost in the Chic-Choc Mountains, south-eastern Canada: a case study from Mont Jacques-Cartier

Published: June 2017

Abstract. We present data on the distribution and thermophysical properties of snow collected sporadically over 4 decades along with recent data of ground surface temperature from Mont Jacques-Cartier (1268 m a.s.l.), the highest summit in the Appalachians of south-eastern Canada. We demonstrate that the occurrence of contemporary permafrost is necessarily associated with a very thin and wind-packed winter snow cover which brings local azonal topo-climatic conditions on the dome-shaped summit. The aims of this study were (i) to understand the snow distribution pattern and snow thermophysical properties on the Mont Jacques-Cartier summit and (ii) to investigate the impact of snow on the spatial distribution of the ground surface temperature (GST) using temperature sensors deployed over the summit. Results showed that above the local treeline, the summit is characterized by a snow cover typically less than 30 cm thick which is explained by the strong westerly winds interacting with the local surface roughness created by the physiography and surficial geomorphology of the site. The snowpack structure is fairly similar to that observed on windy Arctic tundra with a top dense wind slab (300 to 450 kg m−3) of high thermal conductivity, which facilitates heat transfer between the ground surface and the atmosphere. The mean annual ground surface temperature (MAGST) below this thin and wind-packed snow cover was about −1 °C in 2013 and 2014, for the higher, exposed, blockfield-covered sector of the summit characterized by a sporadic herbaceous cover. In contrast, for the gentle slopes covered with stunted spruce (krummholz), and for the steep leeward slope to the south-east of the summit, the MAGST was around 3 °C in 2013 and 2014. The study concludes that the permafrost on Mont Jacques-Cartier, most widely in the Chic-Choc Mountains and by extension in the southern highest summits of the Appalachians, is therefore likely limited to the barren wind-exposed surface of the summit where the low air temperature, the thin snowpack and the wind action bring local cold surface conditions favourable to permafrost development.

Toxicity issues and biocompatibility concerns with traditional classical chemical cross-linking processes prevent them from being universal approaches for hydrogel fabrication for tissue engineering. Physical cross-linking methods are non-toxic and widely used to obtain cross-linked polymers in a tunable manner. Therefore, in the current study, argon micro-plasma was introduced as a neutral energy source for cross-linking in fabrication of the desired gelatin-graphene oxide (gel-GO) nanocomposite hydrogel scaffolds. Argon microplasma was used to treat purified gelatin (8% w/v) containing 0.1∼1 wt% of high-functionality nano-graphene oxide (GO). Optimized plasma conditions (2,500 V and 8.7 mA) for 15 min with a gas flow rate of 100 standard cm3/min was found to be most suitable for producing the gel-GO nanocomposite hydrogels. The developed hydrogel was characterized by the degree of cross-linking, FTIR spectroscopy, SEM, confocal microscopy, swelling behavior, contact angle measurement, and rheology. The cell viability was examined by an MTT assay and a live/dead assay. The pore size of the hydrogel was found to be 287 ± 27 µm with a contact angle of 78° ± 3.7°. Rheological data revealed improved storage as well as a loss modulus of up to 50% with tunable viscoelasticity, gel strength, and mechanical properties at 37 °C temperature in the microplasma-treated groups. The swelling behavior demonstrated a better water-holding capacity of the gel-GO hydrogels for cell growth and proliferation. Results of the MTT assay, microscopy, and live/dead assay exhibited better cell viability at 1% (w/w) of high-functionality GO in gelatin. The highlight of the present study is the first successful attempt of microplasma-assisted gelatin-GO nano composite hydrogel fabrication that offers great promise and optimism for further biomedical tissue engineering applications.
Developmental Model of Intercultural Sensitivity
Authors: Bennett Milton J. 
Published: June 2017

Abstract
The Developmental Model of Intercultural Sensitivity (DMIS) created by Milton J. Bennett is a grounded theory based on constructivist perception and communication theory. It assumes that the experience of reality is constructed through perception, and that more complex perceptual categories yield more complex (sophisticated) experience. Specifically, the DMIS assumes that we are constructing boundaries of “self” and “other” in ways that guide our experience of intercultural events. The most ethnocentric construction, Denial, is one wherein only vague categories of “other” are available for perceiving people from different cultural contexts. At the other end of the continuum, the most ethnorelative construction of Integration supposes that complex self/other categories are incorporated into one's personal identity and into decision‐making regarding ethicality in multicultural relations. This entry describes the theory and application of the DMIS to diagnosis and intervention, including some discussion of measuring intercultural sensitivity and the main criticisms of the model and its measurement.
Composite embedded cubature Kalman filter
Authors: Meng Dong , Miao Lingjuan , Shao Haijun 
Published: June 2017

SummaryThe embedded cubature Kalman filter (ECKF) is proven as a kind of algorithm that has higher precision than cubature Kalman filter. Based on the ECKF, a new algorithm, named composite ECKF (CECKF), is presented in this paper. The new CECKF can increase filter precision by means of reusing the embedded cubature rule in the process of numerical approximation, which can realize higher precision than ECKF in theory. At the same time, another new algorithm, named adaptive CECKF, is also put forward by introducing an adaptive method based on CECKF. Through the comparison of simulation, the proposed methods are able to enhance filter precision.
Towards In Vivo Tumor Detection Using Polarization and Wavelength Characteristics of Self‐Assembled Gold Nanorods

Published: June 2017

AbstractThis work suggests a novel concept for sensing the back‐reflected and absorbed light at two polarization states and at several wavelengths based on self‐assembled gold nanorods (SGNs). While the SGNs are flowing in the bloodstream, the reflected light has a low degree of polarization at the specific wavelength. In comparison, when the SGNs are not moving, such as when the SGNs are located in a tumor, the reflected light has a high degree of polarization. Impressively, the SGNs structures further display a considerably improved contrast in the diffusion reflection (DR) system. Such characteristics provide a new strategy for possible in vivo detection of a tumor with enhanced resolution.
Experimental warming alters migratory caribou forage quality

Published: June 2017

AbstractGlobal declines in caribou and reindeer (Rangifer) populations have drawn attention to the myriad of stressors that these Arctic and boreal forest herbivores currently face. Arctic warming has resulted in increased tundra shrub growth and therefore Rangifer forage quantity. However, its effects on forage quality have not yet been addressed although they may be critical to Rangifer body condition and fecundity. We investigated the impact of 8 yrs of summer warming on the quality of forage available to the Bathurst caribou herd using experimental greenhouses (n = 5) located in mesic birch hummock tundra in the central Canadian Low Arctic. Leaf forage quality and digestibility characteristics associated with nutrients (nitrogen and phosphorus), phenolics, and fiber were measured on the deciduous shrub Betula glandulosa (an important Rangifer diet component) at six time points through the growing season, and on five other very common vascular plant and lichen species in late summer. Experimental warming reduced B. glandulosa leaf nitrogen concentrations by ~10% in both late June and mid‐July, but not afterwards. It also reduced late summer forage quality of the graminoid Eriophorum vaginatum by increasing phenolic concentrations 38%. Warming had mixed effects on forage quality of the lichen Cetraria cucullata in that it increased nutrient concentrations and tended to decrease fiber contents, but it also increased phenolics. Altogether, these warming‐induced changes in forage quality over the growing season, and response differences among species, highlight the importance of Rangifer adaptability in diet selection. Furthermore, the early season reduction in B. glandulosa nitrogen content is a particular concern given the importance of this time for calf growth. Overall, our demonstration of the potential for significant warming impacts on forage quality at critical times for these animals underscores the importance of effective Rangifer range conservation to ensure sufficient appropriate habitat to support adaptability in forage selection in a rapidly changing environment.

AbstractBackgroundNeuropathic pain (NeuP) is a frequent sequel of spinal cord injury (SCI). The SCI Pain Instrument (SCIPI) was developed as a SCI‐specific NeuP screening tool. A preliminary validation reported encouraging results requiring further evaluation in terms of psychometric properties. The painDETECT questionnaire (PDQ), a commonly applied NeuP assessment tool, was primarily validated in German, but not specifically developed for SCI and not yet validated according to current diagnostic guidelines. We aimed to provide convergent construct validity and to identify the optimal item combination for the SCIPI. The PDQ was re‐evaluated according to current guidelines with respect to SCI‐related NeuP.MethodsProspective monocentric study. Subjects received a neurological examination according to the International Standards for Neurological Classification of SCI. After linguistic validation of the SCIPI, the IASP‐grading system served as reference to diagnose NeuP, accompanied by the PDQ after its re‐evaluation as binary classifier. Statistics were evaluated through ROC‐analysis, with the area under the ROC curve (AUROC) as optimality criterion. The SCIPI was refined by systematic item permutation.ResultsEighty‐eight individuals were assessed with the German SCIPI. Of 127 possible combinations, a 4‐item‐SCIPI (cut‐off‐score = 1.5/sensitivity = 0.864/specificity = 0.839) was identified as most reasonable. The SCIPI showed a strong correlation (rsp = 0.76) with PDQ. ROC‐analysis of SCIPI/PDQ (AUROC = 0.877) revealed comparable results to SCIPI/IASP (AUROC = 0.916). ROC‐analysis of PDQ/IASP delivered a score threshold of 10.5 (sensitivity = 0.727/specificity = 0.903).ConclusionThe SCIPI is a valid easy‐to‐apply NeuP screening tool in SCI. The PDQ is recommended as complementary NeuP assessment tool in SCI, e.g. to monitor pain severity and/or its time‐dependent course.SignificanceIn SCI‐related pain, both SCIPI and PainDETECT show strong convergent construct validity versus the current IASP‐grading system. SCIPI is now optimized from a 7‐item to an easy‐to‐apply 4‐item screening tool in German and English. We provided evidence that the scope for PainDETECT can be expanded to individuals with SCI.
Disciplinary Literacy in Engineering
Authors: Wilson‐Lopez Amy , Minichiello Angela 
Published: June 2017

AbstractPeople who practice engineering can make a difference through designing products, procedures, and systems that improve people's quality of life. Literacy, including the interpretation, evaluation, critique, and production of texts and representations, is important throughout the engineering design process. In this commentary, the authors outline texts and interpretive frameworks that are common to each stage of the engineering design process as it is defined by the Next Generation Science Standards. The authors describe how disciplinary literacy can also account for students’ home languages and local bodies of knowledge, in addition to these engineering design standards. Finally, they conclude with a vision of disciplinary literacy as a tool to promote equity by rigorously supporting diverse students through the process of critiquing designs in society and creating ethical and equitable designs.
List coloring digraphs
Authors: Bensmail Julien , Harutyunyan Ararat , Le Ngoc Khang 
Published: June 2017

AbstractThe dichromatic number of a digraph D is the least number k such that the vertex set of D can be partitioned into k parts each of which induces an acyclic subdigraph. Introduced by Neumann‐Lara in 1982, this digraph invariant shares many properties with the usual chromatic number of graphs and can be seen as the natural analog of the graph chromatic number. In this article, we study the list dichromatic number of digraphs, giving evidence that this notion generalizes the list chromatic number of graphs. We first prove that the list dichromatic number and the dichromatic number behave the same in many contexts, such as in small digraphs (by proving a directed version of Ohba's conjecture), tournaments, and random digraphs. We then consider bipartite digraphs, and show that their list dichromatic number can be as large as . We finally give a Brooks‐type upper bound on the list dichromatic number of digon‐free digraphs.
Studies on damping behavior of vertically mixed structures with upper steel and lower concrete substructures
Authors: Lu Zheng , He Xiangdong , Zhou Ying 
Published: June 2017

SummaryThis paper presents 2 models to simulate the damping behavior of a 12‐story vertically mixed structure with upper steel and lower concrete substructures (S/RC structure). One is the modal strain energy damping model based on modal damping ratio. The other is the assembled Rayleigh damping model based on damping matrix that is obtained by combining Rayleigh damping matrix of steel components with that of concrete ones. Then a 12‐story S/RC frame and a 12‐story RC frame are designed and used for shaking table test. Based on the test, the expressions for the damping behavior of steel and concrete substructures of the S/RC frame are derived, and these expressions are utilized to form 2 different damping models of the S/RC structure separately. By comparing the damping behavior of the 2 models in analysis with what has been identified in the tests, the feasibility of the 2 models are assessed in both frequency domain and time domain. Theoretical analysis and experimental results show that the assembled Rayleigh damping model is not applicable to conventional modal analysis because of its nonproportional characteristics. However, the modal strain energy damping model based on equivalence of the dissipated modal strain energy of structure, which embodies the essence of damping, can give better predictions on damping behavior of the S/RC frame in both time and frequency domains. Finally, some suggestions are put forward on the selection of damping parameters in practical seismic design for vertically mixed structures.
