Authors: Finch David J. , Varella Paul , Foster William , Sundararajan Binod , Bates Kim , Nadeau John , O'Reilly Norm , Deephouse David L. 
Published: May 2016

AbstractStakeholder relationships are a critical resource that contribute to or inhibit value creation. Building on this assertion, we explore the value of the business school at a stakeholder level. We draw on research by the Canadian multistakeholder working group, the Business School Research Network (BSRN), which was established to facilitate collaborative interinstitutional research on the management and practice of business schools. We provide a conceptual model of the value chain and associated scorecard that take into account the sources of value judgments that pertain to a business school at the stakeholder‐level.

The optimization of Transparent‐Desktop service mechanism based on SPICE
Authors: Li Weimin , Wang Bin , Yu Jiaqi , Zhu Chong , Xiao Sinuo , Sheng Jinfang 
Published: May 2016

SummaryDesktop virtualization, which is to make the desktop virtual so that users can access any application through the network with any devices at any time and any place, is being widely used now as an emerging trend. However, it is important to further improve this approach while maintaining good user experience. Though the simple protocol for independent computing environments as a virtual desktop solution can achieve a user experience similar to an interaction with a local machine, there are still many deficiencies in it. For instance, it cannot apply to environment of high controllability of user, and the quality of graphic interactive experience is to be improved. In this paper, to meet QoE requirements of user, we build a feasible file transfer and sharing mechanism and propose a graphics subsystem optimization strategy based on simple protocol for independent computing environments (SPICE), namely Transparent Desktop. We also verify that the Transparent Desktop can provide users with ubiquitous desktop services of higher efficiency, stronger user‐controllability and better QoE through the experimental.

Community governance in primary health care: towards an international Ideal Type
Authors: Meads Geoffrey , Russell Grant , Lees Amanda 
Published: May 2016

SummaryAgainst a global background of increased resource management responsibilities for primary health care agencies, general medical practices, in particular, are increasingly being required to demonstrate the legitimacy of their decision making in market oriented environments. In this context a scoping review explores the potential utility for health managers in primary health care of community governance as a policy concept. The review of recent research suggests that applied learning from international health systems with enhanced approaches to public and patient involvement may contribute to meeting this requirement. Such approaches often characterise local health systems in Latin America and North West Europe where innovative models are beginning to respond effectively to the growing demands on general practice. The study design draws on documentary and secondary data analyses to identify common components of community governance from the countries in these regions, supplemented by other relevant international studies and sources where appropriate. Within a comprehensive framework of collaborative governance the components are aggregated in an Ideal Type format to provide a point of reference for possible adaptation and transferable learning across market oriented health systems. Each component is illustrated with international exemplars from recent organisational practices in primary health care. The application of community governance is considered for the particular contexts of GP led Clinical Commissioning Groups in England and Primary Health Networks in Australia. Some components of the Ideal Type possess potentially powerful negative as well as positive motivational effects, with PPI at practice levels sometimes hindering the development of effective local governance. This highlights the importance of careful and competent management of the growing resources attributed to primary health care agencies, which possess an increasingly diverse range of non‐governmental status. Future policy and research priorities are outlined. Copyright © 2016 John Wiley & Sons, Ltd.
Skewness Risk and Bond Prices
Authors: Ruge‐Murcia Francisco 
Published: May 2016

SummaryThis paper uses extreme value theory to study the implications of skewness risk for nominal loan contracts in a production economy. Productivity and inflation innovations are drawn from generalized extreme value distributions. The model is solved using a third‐order perturbation and estimated by the simulated method of moments. Results show that the data reject the hypothesis that innovations are drawn from normal distributions and favor instead the alternative that they are drawn from asymmetric distributions. Estimates indicate that skewness risk accounts for 12% of the risk premia and reduces bond yields by approximately 55 basis points. For a bond that pays 1 dollar at maturity, the adjustment factor associated with skewness risk ranges from 0.15 cents for a 3‐month bond to 2.05 cents for a 5‐year bond.

Curcumin Promotes Osteosarcoma Cell Death by Activating miR‐125a/ERRα Signal Pathway
Authors: Chen Peng , Wang Haibin , Yang Fan , Chen Hongwu , He Wei , Wang Junjian 
Published: May 2016

ABSTRACTCurcumin has demonstrated valuable therapeutic potential against a variety of human cancers including osteosarcoma. However, the molecular mechanisms underlying its anti‐tumor effect remain to be poorly understood. By RNA sequence profiling, we found that curcumin significantly down‐regulates the expression of estrogen‐related receptor alpha (ERRα) in osteosarcoma cells. Overexpression of ERRα diminished curcumin‐activated apoptotic cell death and scavenged curcumin‐induced reactive oxygen species (ROS), while ERRα silencing sensitized osteosarcoma cells to curcumin, resulting in increased inhibition of cell proliferation. In addition, we found that curcumin suppressed the ERRα gene expression through upregulation of miR‐125a. Data from this study revealed a novel mechanism for curcumin‐mediated apoptotic cell death, which involves tumor cell killing via activating miR‐125a/ERRα pathway. Our studies also provide further support for osteosarcoma therapy by targeting ERRα alone or in combination with curcumin. J. Cell. Biochem. 118: 74–81, 2017. © 2016 Wiley Periodicals, Inc.
Human Driving Forces of Oasis Expansion in Northwestern China During the Last Decade—A Case Study of the Heihe River Basin
Authors: Zhou Dingyang , Wang Xiaojun , Shi Minjun 
Published: May 2016

AbstractWater scarcity is one of the most prominent issues worldwide in relation to sustainable development, especially in arid areas. To gain a better understanding of the trade‐off between improving agricultural productivity and maintaining the stability of an oasis ecosystem in these areas, this study took the Heihe River Basin in northwestern China as a case to explore the changes in oasis dynamics and their human driving forces. The results showed that along with the 11·0% expansion of agricultural land, the total water demand for irrigation increased by 6·3% during 2000–2010. Although tremendous economic incentives for farmers spurred the oasis expansion and cropping system changes, the key driving force behind the oasis expansion in the study area was closely related to sufficient irrigation water guaranteed by new water sources (excessive consumption of groundwater and surface water) and water conservation efforts that were the results of the “water‐saving society” project (cropping system adjustments and technological improvements in irrigation). This loose regulation of water resource management can be considered to be partially attributable to the ignorance of the ecological value of water resources. Sustainable land use in the study area can only be achieved through the strict regulation of the management of surface water and groundwater resources throughout the basin and the invisible water provided by the water conservation measures.

Authors: Katsouris Adrianos G. , Nikolopoulos Christos D. , Baklezos Anargyros T. , Capsalis Christos N. 
Published: May 2016

ABSTRACTThis article describes a reconfigurable monopole liquid antenna array, suitable for wireless communications in the UHF band, focusing on obtaining and controlling notch radiation directions. Two different implementations are being studied, at the beginning three collinear monopoles placed over a ground plane and then, five monopoles over a ground plane placed in such a manner as to form a cross. By replacing the parasitic elements with cylinders filled with conductive fluids and also surrounding the driven element, it is possible it is possible to change at will the whole antenna's layout and to control both the maximum directivity angle over the azimuth and the resonant frequency, filtering interfered channels and background noise. © 2016 Wiley Periodicals, Inc.

Unequal termination branch‐line balun with high‐isolation wideband characteristics
Authors: Kim Phirun , Chaudhary Girdhari , Jeong Yongchae 
Published: May 2016

ABSTRACTThis article presents a design of an unequal termination impedance branch‐line balun with wideband high isolation. The wideband and high isolation characteristics are obtained only in the under‐matched region. For an experimental verification, the proposed balun was designed at a center frequency (f0) of 2.6 GHz. The measured results are in good agreement with the simulations. From the measurement, the power divisions are −3.29 dB and −3.3 dB. The return loss at f0 is 22.3 dB and is higher than 20 dB over a bandwidth of 0.51 GHz. The isolation between output ports is higher than 19 dB for the bandwidth of 0.64 GHz. The phase imbalance between two output ports is 180° ± 5° for the bandwidth of 0.64 GHz. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1775–1778, 2016
Wideband substrate‐integrated monopole antenna
Authors: Lawrence Nicholas P. , Fumeaux Christophe , Abbott Derek 
Published: May 2016

ABSTRACTA coaxial probe fed wideband low‐profile electric monopole cavity antenna with measured impedance bandwidth of 56% at a central operating frequency of 8 GHz is proposed. The antenna, based on a modified shorted square patch, effectively forms a substrate‐integrated cavity with four curved radiating slots at its periphery. The concave curvature of these four radiating slots provides a magnetic current loop mode while increasing bandwidth and reducing volume of the resonator. The proposed design may be easily fed using a 50 Ω probe feed and capacitive gap, and is robust to manufacturing tolerances, as parasitic modes are not excited. The design is compatible with applications requiring a vertically polarized signal with respect to the antenna surface. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1855–1857, 2016
Design of trisection bandpass filter based on elliptic‐function filter
Authors: Yang Yang , Cao Ke , Cheng Chong‐Hu 
Published: May 2016

ABSTRACTThis article presents the design and realization of a new bandpass filter (BPF) fabricated on multilayered substrates. The proposed BPF schematic is based on the traditional elliptic‐function filter schematic. The novel schematic features a specific parallel section, which grants the new schematic the ability in reducing the undesirable value of inductors in serial arms of the conventional elliptic BPF circuit schematic. As an illustrative example, a prototype BPF with 800 MHz center frequency is designed and fabricated. The measured stop‐band rejection is better than 45 dB up to 2 GHz, and a relatively narrow bandwidth is obtained. The measured result agrees very well with the electromagnetic (EM) designed response. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1891–1894, 2016

BackgroundPancreatic adenocarcinoma patients have low survival rates due to late‐stage diagnosis and high rates of cancer recurrence even after surgical resection. It is important to understand the molecular characteristics associated with survival differences in pancreatic adenocarcinoma tumors that may inform patient care.ResultsRNA sequencing was performed for 51 patient tumor tissues extracted from patients undergoing surgical resection, and expression was associated with overall survival time from diagnosis. Our analysis uncovered 323 transcripts whose expression correlates with survival time in our pancreatic patient cohort. This genomic signature was validated in an independent RNA‐seq dataset of 68 additional patients from the International Cancer Genome Consortium. We demonstrate that this transcriptional profile is largely independent of markers of cellular division and present a 19‐transcript predictive model built from a subset of the 323 transcripts that can distinguish patients with differing survival times across both the training and validation patient cohorts. We present evidence that a subset of the survival‐associated transcripts is associated with resistance to gemcitabine treatment in vitro, and reveal that reduced expression of one of the survival‐associated transcripts, Angiopoietin‐like 4, impairs growth of a gemcitabine‐resistant pancreatic cancer cell line.ConclusionsGene expression patterns in pancreatic adenocarcinoma tumors can distinguish patients with differing survival outcomes after undergoing surgical resection, and the survival difference could be associated with the intrinsic gemcitabine sensitivity of primary patient tumors. Thus, these transcriptional differences may impact patient care by distinguishing patients who would benefit from a non‐gemcitabine based therapy.
