A Comprehensive Literature Review of the Rank Reversal Phenomenon in the Analytic Hierarchy Process
Authors: Maleki Hamed , Zahir Sajjad 
Published: August 2012

ABSTRACTDuring the last few decades, several multi‐criteria decision analysis methods have been proposed to help in selecting the best compromise alternatives. Among them, analytic hierarchy process (AHP) and its applications have attracted much attention from academics and practitioners. However, since the early 1980s, critics have raised questions regarding its proper use. One of them concerns the unacceptable changes in the ranks of the alternatives, called rank reversal, upon changing the structure of the decision. Several modifications were suggested to preserve ranks. In this paper, a classification scheme and a comprehensive literature review are presented in order to uncover, classify and interpret the current research on AHP methodologies and rank reversals. On the basis of the scheme, 61 scholarly papers from 18 journals are categorized into specific areas. The specific areas include the papers on the topics of adding/deleting alternatives and the papers published in adding/deleting criteria. The scholarly papers are also classified by (1) year of publication, (2) journal of publication, (3) authors' geographic location and (4) using the AHP in association with other methods. It is hoped that the paper can meet the needs of researchers and practitioners for convenient references of AHP methodologies and rank reversals and hence promote the future of rank reversal research.

Microvascular approach to scalp replantation and reconstruction: A thirty‐six year experience
Authors: Herrera Fernando , Buntic Rudolf , Brooks Darrell , Buncke Gregory , Antony Anuja K. 
Published: August 2012

AbstractBackground:Soft tissue defects of the scalp may result from multiple etiologies and can be challenging to reconstruct. We discuss our experience with scalp replantation and secondary microvascular reconstruction over 36 years, including techniques pioneered at our institution with twin–twin scalp allotransplant and innervated partial superior latissimus dorsi (LD) for scalp/frontalis loss.Methods:A retrospective review of all patients presenting with scalp loss requiring microvascular reconstruction at a single center was performed from January 1971 to January 2007. Medical records were reviewed for age, gender, defect size/location, etiology, type of reconstruction, recipient vessels used, vein grafts, and complications.Results:Thirty‐three patients were identified; mean age was 33 years (range, 7–79). Mean scalp defect size was 442 cm2 (range, 120–900 cm2). Thirty‐six microvascular reconstructions were performed; of these, 10 scalp replants and 26 microvascular tissue transfers. Of these 26, 17 were LD based (partial superior LD with and without reinnervation, LD combined with serratus, LD combined with parascapular, LD combined with split rib, LD only) and 2 free scalp allotransplant among others. The superficial temporal artery and vein was used as recipient vessels in 70% of cases. Overall, microvascular success rate was 92%; complications occurred in 14 cases, nine major (tumor recurrence [n = 2], partial flap loss [n = 2], replant loss [n = 3, size <300 cm2], hematoma [n = 2]) and five minor (donor site seroma /hematoma [n = 3], flap congestion [n = 1], superficial wound infection [n = 1]).Conclusions:Every attempt should be made at scalp replantation when the patient is stable and the parts salvageable. Larger avulsion defects had higher success rates after replantation than smaller defects (<300 cm2), with the superficial temporal artery and vein most commonly used for recipient vessels (P = 0.0083). Microvascular tissue transfer remains a mainstay of treatment for scalp defects, with LD‐based flaps, demonstrating excellent versatility for a range of defects. © 2012 Wiley Periodicals, Inc.

Superconvergence of tetrahedral quadratic finite elements for a variable coefficient elliptic equation
Authors: Liu Jinghong , Hu Gui , Zhu Qiding 
Published: August 2012

AbstractFor a variable coefficient elliptic boundary value problem in three dimensions, using the properties of the bubble function and the element cancelation technique, we derive the weak estimate of the first type for tetrahedral quadratic elements. In addition, the estimate for the W1,1‐seminorm of the discrete derivative Green's function is also given. Finally, we show that the derivatives of the finite element solution uh and the corresponding interpolant Π2u are superclose in the pointwise sense of the L∞‐norm. © 2012 Wiley Periodicals, Inc.

Pathological Changes of the Cranium of a Young Female Cave Bear (Ursus spelaeus R.)—A Case Study (the Sudety Mts, Poland)
Authors: Nowakowski D. , Stefaniak K. 
Published: August 2012

AbstractA cranium of a young female cave bear (Ursus spelaeus R.) was found in the Upper Pleistocene sediments of Bear Cave in Kletno, SW Poland. A detailed analysis of the cranium, including radiology, CT and histological methods, revealed numerous pathological changes caused both by diseases and by injuries inflicted by another predator. It is likely that during its lifespan, the young female was exposed to several attacks (bites on the head) from adult bears. The injuries varied in extent and caused bone infection and inflammation. The nature of most of them suggests that they were not fatal but could have had a significant effect on the overall fitness of the animal. In contrast, the lesions on the frontal bone and in the anterior part of the parietal bone may have been the cause of the individual's death. Additionally, the cranium was found to have cut marks, sharp‐edged longitudinal scars that indicate the use of a sharp‐edged tool, and are usually interpreted as effects of skinning. The finding is suggested to be indirect evidence of the existence of people in southern Poland during the Pleistocene. Copyright © 2012 John Wiley & Sons, Ltd.

Dynamics of crystallization with fractal geometry: Extended KJMA approach in glasses
Authors: Shimakawa Koichi 
Published: August 2012

AbstractAlthough the kinetics of crystallization under isothermal annealing conditions in glassy materials is fairly well understood by the Kolmogorov–Johnson–Mehl–Avrami (KJMA) formalism, there is still a matter of debate on its applicability. By introducing a fractal geometry and the Meyer–Neldel rule on thermally activated processes into the KJMA theory, we can overcome some of the difficulties with the classical KJMA mode, with maintaining its intuitive simplicity. Very reasonable physical parameters are deduced from the extended KJMA theory
Finding cycles and trees in sublinear time

Published: August 2012

ABSTRACTWe present sublinear‐time (randomized) algorithms for finding simple cycles of length at least and tree‐minors in bounded‐degree graphs. The complexity of these algorithms is related to the distance of the graph from being Ck‐minor free (resp., free from having the corresponding tree‐minor). In particular, if the graph is ‐far from being cycle‐free (i.e., a constant fraction of the edges must be deleted to make the graph cycle‐free), then the algorithm finds a cycle of polylogarithmic length in time , where N denotes the number of vertices. This time complexity is optimal up to polylogarithmic factors.The foregoing results are the outcome of our study of the complexity of one‐sided error property testing algorithms in the bounded‐degree graphs model. For example, we show that cycle‐freeness of N‐vertex graphs can be tested with one‐sided error within time complexity , where ∊ denotes the proximity parameter. This matches the known query lower bound for one‐sided error cycle‐freeness testing, and contrasts with the fact that any minor‐free property admits a two‐sided error tester of query complexity that only depends on ∊. We show that the same upper bound holds for testing whether the input graph has a simple cycle of length at least k, for any . On the other hand, for any fixed tree T, we show that T‐minor freeness has a one‐sided error tester of query complexity that only depends on the proximity parameter ∊.Our algorithm for finding cycles in bounded‐degree graphs extends to general graphs, where distances are measured with respect to the actual number of edges. Such an extension is not possible with respect to finding tree‐minors in complexity. © 2012 Wiley Periodicals, Inc. Random Struct. Alg., 45, 139–184, 2014
A Brief Discussion About Image Quality and SEM Methods for Quantitative Fractography of Polymer Composites
Authors: Hein L. R. O. , Campos K. A. , Caltabiano P. C. R. O. , Kostov K. G. 
Published: August 2012

SummaryThe methodology for fracture analysis of polymeric composites with scanning electron microscopes (SEM) is still under discussion. Many authors prefer to use sputter coating with a conductive material instead of applying low‐voltage (LV) or variable‐pressure (VP) methods, which preserves the original surfaces. The present work examines the effects of sputter coating with 25 nm of gold on the topography of carbon‐epoxy composites fracture surfaces, using an atomic force microscope. Also, the influence of SEM imaging parameters on fractal measurements is evaluated for the VP‐SEM and LV‐SEM methods. It was observed that topographic measurements were not significantly affected by the gold coating at tested scale. Moreover, changes on SEM setup leads to nonlinear outcome on texture parameters, such as fractal dimension and entropy values. For VP‐SEM or LV‐SEM, fractal dimension and entropy values did not present any evident relation with image quality parameters, but the resolution must be optimized with imaging setup, accompanied by charge neutralization.

Are network effects really all about size? The role of structure and conduct
Authors: Afuah Allan 
Published: August 2012

AbstractRooted in neoclassical economics, network effects research has revolved around size, arguing that the more users a network has, the more valuable that network will be to each user. I argue that a network's structure (feasibility of transactions, centrality of members, structural holes, network ties, the number of roles each member plays) and its conduct (opportunistic behavior, reputation signaling, perceptions of trust) also have significant impacts on a network's value to users and to network providers. Network research that neglects structure and conduct and focuses only on size can lead to wrong strategies or a misleading research agenda. Copyright © 2012 John Wiley & Sons, Ltd.

Published: August 2012

AbstractThe static and dynamic wetting properties of a 3D graphene foam network are reported. The foam is synthesized using template‐directed chemical vapor deposition and contains pores several hundred micrometers in dimension while the walls of the foam comprise few‐layer graphene sheets that are coated with Teflon. Water contact angle measurements reveal that the foam is superhydrophobic with an advancing contact angle of ∼163 degrees while the receding contact angle is ∼143 degrees. The extremely water repellent nature of the foam is also confirmed when impacting water droplets are able to completely rebound from the surface. Such superhydrophobic graphene foams show potential in a variety of applications ranging from anti‐sticking and self‐cleaning to anti‐corrosion and low‐friction coatings.
Mechanical Joining of Tubes to Sheets Along Inclined Planes
Authors: Alves Luis M. , Martins Paulo A. F. 
Published: August 2012

AbstractThis paper presents a new mechanical joining process for fixing tubes to sheets along planes inclined with respect to the tube axis. The process is based on the capacity of producing and controlling inclined instability waves in thin‐walled tubes subjected to axial compressive load and is capable of ensuring significant economic and time savings when compared to currently available joining technologies. The presentation includes details on tool design, independent determination of the mechanical properties of the materials, numerical modeling, and experimentation under laboratory conditions with the aim of determining the process window as a function of the major operative parameters. The feasibility of joining tubes to sheets along inclined planes is demonstrated by presenting one connection performed at the tube end and another connection performed away from the tube end.

Asset allocation in markets with contagion: The interplay between volatilities, jump intensities, and correlations
Authors: Konermann Patrick , Meinerding Christoph , Sedova Olga 
Published: August 2012

AbstractWe study the impact of financial contagion on the dynamic asset allocation problem of a CRRA investor facing an incomplete market with two risky assets. We apply a Markov chain regime‐switching framework with state‐dependent jump intensities, diffusion volatilities and diffusion correlations. The key model feature that a switch to the bad contagion regime is triggered by a loss in one of the risky assets allows for the implementation of a hedging demand against contagion risk. Moreover, a state‐dependent diffusion correlation combined with heterogeneity in jump intensities and volatilities can, e.g., generate a flight to quality effect upon a systemic jump.
Contributions to the geometric and ergodic theory of conservative flows
Authors: BESSA MÁRIO , ROCHA JORGE 
Published: August 2012

AbstractWe prove the following dichotomy for vector fields in a $C^1$-residual subset of volume-preserving flows: for Lebesgue-almost every point, either all of its Lyapunov exponents are equal to zero or its orbit has a dominated splitting. Moreover, we prove that a volume-preserving and $C^1$-stably ergodic flow can be $C^1$-approximated by another volume-preserving flow which is non-uniformly hyperbolic.
Anician Myths
Authors: Cameron Alan 
Published: August 2012

AbstractThis paper discusses the widely held view that politics in fifth- and sixth-century Italy were largely driven by rivalry between the two great families of the Anicii and the Decii, supposedly following distinctive policies (pro- or anti-eastern, philo- or anti-barbarian, etc.). It is probable that individual members of these (and other) families had feuds and disagreements from time to time, but there is absolutely no evidence for continuing rivalry between Decii and Anicii as families, let alone on specific issues of public policy. Indeed by the mid-fifth century the Anicii fell into a rapid decline. The nobility continued to play a central rôle in the social and (especially) religious life of late fifth- and early sixth-century Italy. Their wealth gave them great power, but it was power that they exercised in relatively restricted, essentially traditional fields, mainly on their estates and in the city of Rome. The quite extraordinary sums they spent on games right down into the sixth century illustrate their overriding concern for popular favour at a purely local level. In this context there was continuing competition between all noble families rich enough to compete. Indeed, the barbarian kings encouraged the nobility to spend their fortunes competing with each other to the benefit of the city and population of Rome.
Symposium: The contexualization of teaching and learning English as an international language
Authors: Chen Yuan-Shan 
Published: August 2012

Presented at the 16th World Congress of Applied Linguistics (AILA), Beijing Foreign Studies University, China, 24 August 2011.SLA research has long been challenged by the flawed comparison of L2 learners to native speakers (Bley-Vroman 1983). Since the start of the new millennium, applied linguists have paid increasing attention to studies of English as a lingua franca (ELF), defined as ‘communication in English between speakers with different first languages’ (Seidlhofer 2005: 339). From the ELF perspective, L2 speakers of English are no longer considered as ‘failed native speakers’ who produce problematic talk, but as ‘highly skilled communicators’ (Jenkins, Cogo & Dewey 2011: 284) who attempt to use multilingual resources to achieve their communicative goals.
Symposium: (Dis)ordered processes of globalization: Policing and voicing language identities

Published: August 2012

Presented at the 16th World Congress of Applied Linguistics (AILA), Beijing Foreign Studies University, China, 27 August 2011.This symposium aimed to capture the multiple and dynamic processes of language and identity in the context of globalization. The pervasive process of globalization has inevitably affected the previously existing social and linguistic order. Broad, stable and normal patterns of conduct are being deconstructed and reshuffled; multiple, overlapping and conflicting forms are being shaped and reshaped. The abnormal becomes normal; disorder becomes the new order. The symposium explored this issue from two complementary perspectives – a macro perspective that focuses on language policies, and a micro perspective that focuses on how people struggle to articulate their identities.

Published: August 2012

AbstractIntroductionThe prevalence of right ventricular dysfunction in idiopathic dilated cardiomyopathy is incompletely studied in children. Furthermore, right ventricular function may signal worse outcomes. We evaluated recently published right ventricular function echocardiographic indices in identifying dysfunction in children with idiopathic dilated cardiomyopathy and the impact of right ventricular dysfunction on long-term prognosis.MethodsA retrospective database review of right ventricular function indices in 30 patients with idiopathic dilated cardiomyopathy was compared with 60 age- and sex-matched controls from January, 2001 until December, 2010. Right ventricular function was assessed by Doppler tissue peak systolic S′, early and late diastolic E′ and A′ waves and isovolumic acceleration at the tricuspid valve annulus; pulsed wave Doppler tricuspid valve inflow E and A waves; right ventricular myocardial performance index; tricuspid annular plane systolic excursion; right ventricular fractional area change.ResultsRight ventricular systolic and diastolic function in idiopathic dilated cardiomyopathy was significantly impaired. All measured indices except for isovolumic acceleration and fractional area change were significantly reduced, with a p-value less than 0.05. There was no right ventricular index predictive of death or transplantation. Patients with poor outcome were significantly more likely to need inotropic support (p-value equal to 0.018), be placed on a ventricular assist device (p equal to 0.005), and have a worse left ventricular ejection fraction z-score (p-value equal to 0.002).ConclusionRight ventricular dysfunction is under-recognised in children presenting with idiopathic dilated cardiomyopathy. The need for clinical circulatory support and left ventricular ejection fraction z-score less than minus 8 were primary determinants of outcome, independent of the degree of derangement in right ventricular function.

Abstract
Semidwarfism has been used extensively in row crops and horticulture to promote yield, reduce lodging, and improve harvest index, and it might have similar benefits for trees for short-rotation forestry or energy plantations, reclamation, phytoremediation, or other applications. We studied the effects of the dominant semidwarfism transgenes GA Insensitive (GAI) and Repressor of GAI-Like, which affect gibberellin (GA) action, and the GA catabolic gene, GA 2-oxidase, in nursery beds and in 2-year-old high-density stands of hybrid poplar (Populus tremula × Populus alba). Twenty-nine traits were analyzed, including measures of growth, morphology, and physiology. Endogenous GA levels were modified in most transgenic events; GA20 and GA8, in particular, had strong inverse associations with tree height. Nearly all measured traits varied significantly among genotypes, and several traits interacted with planting density, including aboveground biomass, root-shoot ratio, root fraction, branch angle, and crown depth. Semidwarfism promoted biomass allocation to roots over shoots and substantially increased rooting efficiency with most genes tested. The increased root proportion and increased leaf chlorophyll levels were associated with changes in leaf carbon isotope discrimination, indicating altered water use efficiency. Semidwarf trees had dramatically reduced growth when in direct competition with wild-type trees, supporting the hypothesis that semidwarfism genes could be effective tools to mitigate the spread of exotic, hybrid, and transgenic plants in wild and feral populations.
