Educational policy borrowing in a globalized world
Authors: Van Huy Nguyen , Hamid M. Obaidul 
Published: June 2015

Purpose
– This paper aims to shed light on the process of adopting and accommodating a global language education framework, namely the Common European Framework of Reference (CEFR) for languages, in the context of Vietnam.

Design/methodology/approach
– The data to develop the argument of the paper are obtained from a doctoral research project that aims to understand the reception, interpretations and responses of key stakeholders in the process of enacting the CEFR in a Vietnam public university. The study was designed as a qualitative case study with data being collected using policy document analysis, classroom observation and in-depth interviews with 21 purposively sampled participants, including school administrators, English language teachers and students over a period of six months.

Findings
– The paper argues that the adoption of the CEFR, as it currently stands, can be seen at best as a “quick-fix” (Steiner-Khamsi, 2004, p. 58) solution to the complex and time-consuming problem of improving the quality of English language education in Vietnam, which fails to address some critical issues in the practice of teaching and learning the language in the country.

Originality/value
– The study speaks to the body of literature on the CEFR as a contemporary global language policy borrowing phenomenon in developing countries. It contributes to a better understanding of how a global language policy is adopted and appropriated at the grass-root level.
Shape changing and self-reconfiguring robots
Authors: Bogue Robert 
Published: June 2015

Purpose
– This article aims to provide details of recent developments in robots that can change shape and self-reconfigure.

Design/methodology/approach
– Following an introduction, this article first describes some recent developments in shape-changing materials and then considers a selection of shape-changing robots. It then discusses self-reconfiguring robots and describes a unique self-unfolding robot. Finally, concluding comments are drawn.

Findings
– This article shows that research into true shape-changing robots is still at an early stage and several very different strategies are being studied. Novel materials are expected to play a key role in many designs and potential applications include search and rescue, health care and surveillance. Self-reconfiguring modular robots are at a more advanced stage and while many can reconfigure to adopt varying shapes and gaits, the ability to accomplish differing tasks in manufacturing is still some way in the future. Overall, the various classes of shape-changing robots being studied represent a move towards a new era in robotic capabilities, but despite many recent technological advances, considerable further work is required before these become a practical reality.

Originality/value
– This article provides an insight into recent technological advances in shape-changing and self-reconfiguring robots.
Optimization of police facility deployment with a case study in Greater London Area
Authors: Cheung Chun-Yin , Yoon H.T. , Chow Andy HF 
Published: June 2015

Purpose
– This paper aims to present an application of location optimization techniques for deploying police facilities subject to budgetary and feasibility constraints. The objectives considered included minimizing the distances and maximizing the coverage of police stations over potential crime spots.

Design/methodology/approach
– The optimization consists of two stages. In Stage 1, a minimum distance model is used to determine the locations of police stations. Given the locations of police stations, Stage 2 uses a maximum coverage model to determine the police patrol area. The framework is applied to a case in the Greater London Area. The authors also evaluate the resilience of the optimal solutions with the terrorist attack scenario on 7 July 2005 in Central London.

Findings
– With the optimization models, it is shown that the average distance between police stations and potential crime spots is reduced by 19 per cent. The coverage percentage of potential crime spots is also increased from the existing 91.99 per cent to a nearly perfect 99.82 per cent. Nevertheless, the results reveal that the optimal police resources deployment is less resilient with respect to the existing one. The findings herein suggest the importance of incorporating measures of resilience into the optimization framework and the authors leave this topic for further investigation.

Originality/value
– The study highlights the value of location optimization to police force deployment in terms of finding the optimal locations of police force with respect to the spatial distribution of crimes. In particular, the authors investigate its implication on urban resilience, which is among the first study of this kind.
The effect of LEED certification on Shanghai’s prime office rental value
Authors: Hui Eddie Chi-man , Chan Eric Wing-fai , Yu Ka-hung 
Published: June 2015

Purpose– This study aims to examine whether Leadership in Energy and Environmental Design (LEED) certification yields additional premiums for Shanghai’s office rental sector.Design/methodology/approach– The hedonic model is utilized to evaluate the impact of LEED, as well as of other factors, on the rental values of 59 Grade A office buildings in Shanghai, including 23 LEED-certified buildings and 36 non-LEED-certified buildings.Findings– It is found that rental values of buildings with LEED are about 12.8 per cent than those of buildings without the same certification. Other factors, for instance accessibility to facilities such as subway station and 4-star hotels, the availability of catering services in surrounding areas as well as the building’s location (i.e. inside the CBD) also are significantly positively correlated with office rents in the sample commercial buildings.Originality/value– Besides being one of the earlier contributions to the literature with regard to the study of the impact of green certifications in China’s office market, the findings in this study also provide some empirical evidence for stakeholders, such as developers, investors, property managers and market practitioners, to evaluate the introduction of green features (and/or green certifications such as LEED) as an investment decision.
Power matters: the importance of Foucault’s power/knowledge as a conceptual lens in KM research and practice
Authors: Heizmann Helena , Olsson Michael R. 
Published: June 2015

Purpose– The purpose of this paper is to engage knowledge management (KM) researchers and practitioners with Foucault’s power/knowledge lens as a way of thinking about and recognising the central role of power in organisational knowledge cultures.Design/methodology/approach– The empirical illustrations in this paper are drawn from two qualitative studies in different professional and institutional contexts (insurance and theatre work). Both studies used in-depth interviews and discourse analysis as their principal methods of data collection and analysis.Findings– The empirical examples illustrate how practitioners operate within complex power/knowledge relations that shape their practices of knowledge sharing, generation and use. The findings show how an application of the power/knowledge lens renders visible both the constraining and productive force of power in KM.Research limitations/implications– Researchers may apply the conceptual tools presented here in a wider variety of institutional and professional contexts to examine the complex and multifaceted role of power in a more in-depth way.Practical implications– KM professionals will benefit from an understanding of organisational power/knowledge relations when seeking to promote transformational changes in their organisations and build acceptance for KM initiatives.Originality/value– This paper addresses a gap in the literature around theoretical and empirical discussions of power as well as offering an alternative to prevailing resource-based views of power in KM.

Published: June 2015

BackgroundStudies have suggested that in the presence of approximal cavities, the approximal surface in contact with this one shows a higher risk in the development of caries lesions.AimTo evaluate the ability of dental materials to prevent and to arrest caries lesion in approximal surfaces in contact with occlusoproximal restorations.DesignTwo independent reviewers performed a literature search in PubMed through November 2014. The inclusion criteria were: (1) subject related to the scope of this systematic review, (2) study with follow‐up, (3) not performed in specific groups, (4) to have a comparison group. After selection by title and abstract, potentially eligible articles were read in full. Meta‐analysis was carried out considering the outcome as caries lesion progression or arrestment.ResultsThe search strategy identified 772 potentially relevant studies, and 10 of them were included in the review (six laboratory studies and four longitudinal trials). For the longitudinal clinical trials, no difference was verified among the materials (OR = 0.680,95%CI:0.233–1.983). When a meta‐analysis was performed for laboratory studies, GIC was significantly associated with better ability to arrest caries lesions (OR = 0.153,95%CI:0.060–0.391).ConclusionsIn laboratory studies, GIC shows better ability to arrest caries lesion in approximal adjacent surfaces, but this ability was not confirmed in longitudinal clinical trials.
Branched coverings and Steiner ratio
Authors: Ivanov A. O. , Tuzhilin A. A. 
Published: June 2015

AbstractFor a branched locally isometric covering of metric spaces with intrinsic metrics, it is proved that the Steiner ratio of the base is not less than the Steiner ratio of the total space of the covering. As applications, it is shown that the Steiner ratio of the surface of an isosceles tetrahedron is equal to the Steiner ratio of the Euclidean plane, and that the Steiner ratio of a flat cone with angle of at its vertex is also equal to the Steiner ratio of the Euclidean plane.
AGGLOMERATION, CONGESTION, AND U.S. REGIONAL DISPARITIES IN EMPLOYMENT GROWTH
Authors: Saito Hisamitsu , Wu JunJie 
Published: June 2015

ABSTRACTWide regional disparities exist in U.S. employment growth. To identify the causes of this disparities, we assess the relative contribution of locational characteristics to regional employment growth in the United States from 2001 to 2010 by estimating an employment growth model with the spatial‐lag effect. Results show that, at the margin, congestion effects dominate localized scale externalities in urban counties. A diverse industrial structure and rich human capital are the main factors that contribute to regional disparities in employment growth. Significant spatial‐lag effects indicate that spatial targeting and regional coordination are necessary to maximize the effectiveness of employment growth policies.
Fine roots are the dominant source of recalcitrant plant litter in sugar maple‐dominated northern hardwood forests
Authors: Xia Mengxue , Talhelm Alan F. , Pregitzer Kurt S. 
Published: June 2015

Summary

Most studies of forest litter dynamics examine the biochemical characteristics and decomposition of leaf litter, but fine roots are also a large source of litter in forests.

We quantified the concentrations of eight biochemical fractions and nitrogen (N) in leaf litter and fine roots at four sugar maple (Acer saccharum)‐dominated hardwood forests in the north‐central United States. We combined these results with litter production data to estimate ecosystem biochemical fluxes to soil. We also compared how leaf litter and fine root biochemistry responded to long‐term simulated N deposition.

Compared with leaf litter, fine roots contained 2.9‐fold higher acid‐insoluble fraction (AIF) and 2.3‐fold more condensed tannins; both are relatively difficult to decompose. Comparatively, leaf litter had greater quantities of more labile components: nonstructural carbohydrates, cellulose and soluble phenolics. At an ecosystem scale, fine roots contributed over two‐thirds of the fluxes of AIF and condensed tannins to soil. Fine root biochemistry was also less responsive than leaf litter to long‐term simulated N deposition.

Fine roots were the dominant source of difficult‐to‐decompose plant carbon fractions entering the soil at our four study sites. Based on our synthesis of the literature, this pattern appears to be widespread in boreal and temperate forests.

AbstractInteraction between TL1A and death receptor 3 (DR3) co‐stimulates T cells, induces production of several pro‐inflammatory cytokines and has been linked to pathogenesis of inflammatory bowel disease (IBD). This study aimed to establish a link between expression of TL1A and selected TL1A‐induced pro‐inflammatory cytokines involved in IBD pathogenesis (IL‐4, IL‐13, IL‐17A and IFN‐γ) and to investigate a connection between serum concentration of TL1A in patients with IBD and activation of peripheral blood T cells. Elevated levels of IL‐4 (2.91‐fold) and IL‐13 (4.05‐fold) mRNA were detected in the inflamed colon mucosa of patients with ulcerative colitis (UC), IFN‐γ mRNA was upregulated (3.23‐fold) in the inflamed colon mucosa of patients with Crohn's disease (CD), whereas upregulation of IL‐17A and TL1A mRNA was present in the inflamed colon mucosa of patients with both CD and UC (IL‐17A: 4.48‐fold and 2.74‐fold, TL1A: 3.19‐fold and 3.22‐fold, respectively) vs. control subjects. We did not detect any changes in DR3 mRNA expression in the investigated groups of patients. TL1A mRNA level in colon mucosa of patients with IBD correlated only with the level of IL‐17A mRNA but no other investigated cytokines. In colon mucosa, expression of TL1A and DR3 was localized to enterocytes and lamina propria mononuclear cells. We did not find any correlation between serum concentrations of TL1A and IL‐17A or changes of CD4(+) or CD8(+) lymphocytes phenotype in patients with IBD. Therefore, our data indicate that TL1A may contribute to pathogenesis of IBD via local but not systemic induction of IL‐17A but not IL‐4, IL‐13 or IFN‐γ.
IL‐37 Expression is Upregulated in Patients with Tuberculosis and Induces Macrophages Towards an M2‐like Phenotype

Published: June 2015

AbstractInterleukin‐37 (IL‐37), a member of the IL‐1 family, primarily functions as an anti‐inflammatory cytokine, reducing inflammation and suppressing the immune response. However, the expression and role of IL‐37 in tuberculosis (TB) remains unknown. We aimed to measure serum levels of IL‐37 and several important cytokines in 25 patients with active TB and to analyse their association with disease activity. We found that IL‐37 levels decreased in patients with TB and recovered after treatment. IL‐37 levels negatively correlated with the serum concentration of IFN‐γ and IL‐12 but positively correlated with IL‐10 and TGF‐β levels. After IL‐37, secretion was blocked in peripheral blood mononuclear cells from active patients with TB, IFN‐γ and IL‐10 production was significantly upregulated; this was not observed in healthy donors or patients after treatment. IL‐37 knockdown significantly enhanced the phagocytic activity of THP1‐derived macrophages towards Mycobacterium tuberculosis (M. tb). M1/M2 polarization‐associated markers were detected simultaneously, and IL‐37 induced a phenotypic shift in THP1‐derived macrophages towards a high CD206+ and low CD86+ macrophage subtype. Furthermore, this phenotypic shift was accompanied by upregulated mRNA levels of arginase 1, TGF‐β and IL‐10, which are characteristic hallmarks of M2 macrophages. In conclusion, our results suggest that increased levels of IL‐37 in patients with TB are associated with IFN‐γ, IL‐12, IL‐10 and TGF‐β levels and that IL‐37 plays a pathological role in TB infection by inhibiting the production of pro‐inflammatory cytokines and inducing macrophages towards an M2‐like phenotype. Thus, IL‐37 may be a novel research target to understand the pathogenesis of TB infection.
