Evaluative Language Beyond Bags of Words: Linguistic Insights and Computational Applications
Authors: Benamara Farah , Taboada Maite , Mathieu Yannick
Published: December 2016

The study of evaluation, affect, and subjectivity is a multidisciplinary enterprise, including sociology, psychology, economics, linguistics, and computer science. A number of excellent computational linguistics and linguistic surveys of the field exist. Most surveys, however, do not bring the two disciplines together to show how methods from linguistics can benefit computational sentiment analysis systems. In this survey, we show how incorporating linguistic insights, discourse information, and other contextual phenomena, in combination with the statistical exploitation of data, can result in an improvement over approaches that take advantage of only one of these perspectives. We first provide a comprehensive introduction to evaluative language from both a linguistic and computational perspective. We then argue that the standard computational definition of the concept of evaluative language neglects the dynamic nature of evaluation, in which the interpretation of a given evaluation depends on linguistic and extra-linguistic contextual factors. We thus propose a dynamic definition that incorporates update functions. The update functions allow for different contextual aspects to be incorporated into the calculation of sentiment for evaluative words or expressions, and can be applied at all levels of discourse. We explore each level and highlight which linguistic aspects contribute to accurate extraction of sentiment. We end the review by outlining what we believe the future directions of sentiment analysis are, and the role that discourse and contextual information need to play.

Published: December 2016

Understanding how major life history traits such as body size and mass and growth change in response to resource availability is crucial in explaining life history trade-offs. We conducted a laboratory experiment with three (high, medium and low) feeding intensity treatments using metamorphs of two spadefoot toads species,Pelobates syriacusandP. fuscus, from syntopic populations. We tested how total food consumption, final body size and mass, body mass increase, body mass and length growth rates and growth efficiency are influenced by food availability. The responses to food availability differed significantly between the species with respect to the total food consumption, body mass increase, body mass growth rate and growth efficiency (i.e. the ratio between total amount of food consumed during the experiment divided by the increase in body mass).P. syriacusmetamorphs had higher growth rates and growth efficiency thanP. fuscusjuveniles. Also,P. syriacusjuveniles responded to differences in food level by increasing growth efficiency with decreasing food levels. OverallP. syriacusseems better adapted to shortages in food availability thanP. fuscus. Our results clearly indicate that the differences in body size between the two species originate between metamorphosis and sexual maturity.
Evaluation of proteases and protease inhibitors in Heterodera glycines cysts obtained from laboratory and field populations
Authors: Masler Edward P. , Chitwood David J.
Published: December 2016

Proteases and protease inhibitors were evaluated in preparations ofHeterodera glycinescysts (nHglCE) obtained from glasshouse cultures (GH) and a field (LR) population. Using a FRET-peptide library comprising 512 peptide substrate pools that detect four endoprotease types (aspartic, cysteine, metallo- and serine), we found that the relative distributions of six endoproteases within the four catalytic types were similar among GH and LR preparations. However, levels of mean protease activity ( s−1(μg nHglCE)−1) across all 512 pools varied nearly eight-fold among the preparations. This variation was not related to cyst source. These qualitative (type distribution) and quantitative relationships persisted when analysis was restricted to the top 40% (activity) pools. Analysis of the top 4% of activity pools revealed some substrate cleavage site preferences between the GH and LR proteases. GH and LR preparations also differed significantly in digestion rates of trypsin and matrix metalloprotease (MMP) substrates, with LR rates two-fold greater than GH rates for each protease. By contrast, inhibition of trypsin activity inMeloidogyne incognitaextracts by heat-denatured preparations (hHglCE) was 1.6-fold greater with GH hHglCE than with LR hHglCE. Inhibition of MMP activity was the same (>60%) for each hHglCE. Fractionation of GH and LR hHglCE preparations by RP-HPLC (CH3CN/0.1% TFA system) yielded protease inhibition profiles that were similar for GH and LR. MMP inhibitors eluted at 35-40% CH3CN, and trypsin inhibitors eluted at both 5% and 35-40% CH3CN, suggesting the possibility of peptide as well as other small molecular weight inhibitors. These discoveries illustrate the importance of examiningH. glycinescysts as a source of materials for novel nematode controls.

LA PETITION TAGALE CAMING MANGA ALIPIN (1665)
Authors: Potet Jean-Paul
Published: December 2016

A rare prose document, this petition from Mindoro magistrates to the Archbishop of Manila - dated December 28, 1665 - provides insights into the state of Tagalog in the middle of the Seventeenth Century, and into its use as an administrative medium.

The text's main features are important variations of Latin and baybáyin characters, the use of ay as a multi-level discourse marker, an aspectual contrast between -ungm- and -um-, an odd magpag- verbal form, ka- as a quasi-specifier, and the use of the second person singular to address a lord.

North Africa is the world’s largest source of dust, a large part of which is transported across the Atlantic to the Caribbean and beyond where it can impact radiation and clouds. Many aspects of this transport and its climate effects remain speculative. The Saharan Aerosol Long-Range Transport and Aerosol–Cloud-Interaction Experiment (SALTRACE; www.pa.op.dlr.de/saltrace) linked ground-based and airborne measurements with remote sensing and modeling techniques to address these issues in a program that took place in 2013/14. Specific objectives were to 1) characterize the chemical, microphysical, and optical properties of dust in the Caribbean, 2) quantify the impact of physical and chemical changes (“aging”) on the radiation budget and cloud microphysical processes, 3) investigate the meteorological context of transatlantic dust transport, and 4) assess the roles of removal processes during transport.

SALTRACE was a German-led initiative involving scientists from Europe, Cabo Verde, the Caribbean, and the United States. The Falcon research aircraft of the Deutsches Zentrum für Luft- und Raumfahrt (DLR), equipped with a comprehensive aerosol and wind lidar payload, played a central role. Several major dust outbreaks were studied with 86 h of flight time under different conditions, making it by far the most extensive investigation on long-range transported dust ever made.

This article presents an overview of SALTRACE and highlights selected results including data from transatlantic flights in coherent air masses separated by more than 4,000-km distance that enabled measurements of transport effects on dust properties. SALTRACE will improve our knowledge on the role of mineral dust in the climate system and provide data for studies on dust interactions with clouds, radiation, and health.

Post-traumatic stress in pregnant women with primary cytomegalovirus infection and risk of congenital infection in newborns
Authors: Vadini Francesco , Tracanna Elisa , Polilli Ennio , Tontodonati Monica , Ricci Elena , Santilli Francesca , Parruti Giustino
Published: December 2016

Background

Substantial evidence indicates that perinatal mental disturbances are associated with the risk for negative maternal-newborn outcomes. A neuroendocrine brain-placenta interaction has been described to explain the association between prenatal stress-related disorders and placental abnormalities. Whether these mechanisms may affect the likelihood of mother-to-child transmission (MTCT) of infections has never been investigated.

Aims

To evaluate the role of psychological factors in cytomegalovirus (CMV) MTCT in pregnant women with primary CMV infection.

Method

A cohort of 276 pregnant women with primary CMV infection underwent assessment of (a) reactive psychopathological symptoms, such as current depressive symptoms and ongoing symptoms of post-traumatic stress disorder; and (b) stable personality traits, such as alexithymia and Type D (distressed) personality. Congenital infection was diagnosed by CMV DNA amplification from blood and/or urine and saliva from newborn at birth.

Results

The occurrence of congenital CMV disease in the newborn was independently predicted by post-traumatic stress symptoms during pregnancy.

Conclusions

Our findings suggest that psychological stress-related disturbances may weaken the physical and immunological barrier against the mother-to-fetus transmission of viruses.

Published: December 2016

Context:

Primary ovarian insufficiency (POI) is caused by ovarian follicle depletion or follicle dysfunction, characterized by amenorrhea with elevated gonadotropin levels. The disorder presents as absence of normal progression of puberty.

Objective:

To elucidate the cause of ovarian dysfunction in a family with POI.

Design:

We performed whole-exome sequencing in 2 affected individuals. To evaluate whether DNA double-strand break (DSB) repair activities are altered in biallelic mutation carriers, we applied an enhanced green fluorescent protein-based assay for the detection of specific DSB repair pathways in blood-derived cells.

Setting:

Diagnoses were made at the Pediatric Endocrine Clinic, Clalit Health Services, Sharon-Shomron District, Israel. Genetic counseling and sample collection were performed at the Pediatric Genetics Unit, Schneider Children’s Medical Center Israel, Petah Tikva, Israel.

Patients and Intervention:

Two sisters born to consanguineous parents of Israeli Muslim Arab ancestry presented with a lack of normal progression of puberty, high gonadotropin levels, and hypoplastic or absent ovaries on ultrasound. Blood samples for DNA extraction were obtained from all family members.

Main Outcome Measure:

Exome analysis to elucidate the cause of POI in 2 affected sisters.

Results:

Analysis revealed a stop-gain homozygous mutation in the SPIDR gene (KIAA0146) c.839G>A, p.W280*. This mutation altered SPIDR activity in homologous recombination, resulting in the accumulation of 53BP1-labeled DSBs postionizing radiation and γH2AX-labeled damage during unperturbed growth.

Conclusions:

SPIDR is important for ovarian function in humans. A biallelic mutation in this gene may be associated with ovarian dysgenesis in cases of autosomal recessive inheritance.
Syntheses, Crystal Structures and Solid-State Absorption Spectra of n-Propylsulfanyl- and Isopropylsulfanyl-Substituted 2,5-Di(1,3-dithiol-2-ylidene)-1,3-dithiolane-4-thione Derivatives with Methoxycarbonyl Groups

Published: December 2016

N-propylsulfanyl and isopropylsulfanyl substituted 2,5-di(1,3-dithiol-2-ylidene)-1,3-dithiolane-4-thione derivatives with methoxycarbonyl groups were synthesized, and their redox and electronic properties and crystal structures were investigated. Solid-state absorption spectra showed that both derivatives absorb almost all visible light. Furthermore isopropylsulfanyl-substituted derivatives absorb near-infrared light and the absorption edge reaches around 1320 nm. The crystal structures show that both derivatives are stacked in one dimension to form a columnar structure, but the molecular arrangements of their columns were quite different from each other. The stacked n-propylsulfanyl derivatives kept their orientation of thiocarbonyl groups in the same direction and the one molecule of the isopropylsulfanyl derivatives were rotated in relation to each other by an angle of 56° about their longer molecular axis. The TD-DFT calculation of stacked molecules suggests that the molecular arrangement among the stacked molecules affects the maximum absorption in near-infrared region.
Postoperative quality of life, satisfaction, and skin condition after varicose vein surgery
Authors: Bruning G. , Langenbruch A. , Augustin M. , Kath W.
Published: December 2016

Compression is performed postoperatively with the intention of minimising side effects, such as bleeding and haematoma in the area of operation, as well as postoperative oedema and pain. Compression stocking manufacturing has incorporated the addition of skin care products into the yarn material in recent years. However, the benefits of these products remain controversial. In addition, the length of the compression stocking is disputed in terms of its effectiveness. This effectiveness was investigated in the present study.

Before surgery, 160 patients with indication of surgical removal of varicose veins were randomly divided into four groups with different types of compression stockings in each case. In each group, 40 patients received a knee-length stocking (length A–D), thigh-length stocking (length A–G), knee-length stocking with Aloe vera or thigh-length stocking with AV. At time 0 (before surgery), one week and 8 weeks after surgery, skin moisture was measured as an objective parameter, quality of life was determined using the Freiburger questionnaire of quality of life in veinous disease (FLQA-vs), benefit to patients was evaluated using the patient benefit index (PBI-v) and further subjective parameters were investigated with a free-text questionnaire. After surgery, the extent of haematoma was determined using the point count method.

After surgery, at both post-operative times, the FLQA-vs decreased significantly (corresponding to a better quality of life), and the PBI-v increased. In the group with Aloe, pruritus was significantly lower, comfort and skin moisture were increased, and skin condition was significantly improved. The extent of haematoma decreased regardless of the length of the stockings.

A benefit of AV as a skin care additive was observed. This finding was objectively confirmed based on the skin moisture. The multifactorial quality of life was not affected by the skin care additive. Thigh-length compression stockings did not provide a measurable benefit.
Quantification and determinants of the amount of respiratory syncytial virus (RSV) shed using real time PCR data from a longitudinal household study
Authors: Wathuo Miriam , Medley Graham F. , Nokes D.J. , Munywoki Patrick K.
Published: December 2016

Background: A better understanding of respiratory syncytial virus (RSV) epidemiology requires realistic estimates of RSV shedding patterns, quantities shed, and identification of the related underlying factors.

Methods: RSV infection data arise from a cohort study of 47 households with 493 occupants, in coastal Kenya, during the 2009/2010 RSV season. Nasopharyngeal swabs were taken every 3 to 4 days and screened for RSV using a real time polymerase chain reaction (PCR) assay. The amount of virus shed was quantified by calculating the ‘area under the curve’ using the trapezoidal rule applied to rescaled PCR cycle threshold output. Multivariable linear regression was used to identify correlates of amount of virus shed.

Results: The median quantity of virus shed per infection episode was 29.4 (95% CI: 15.2, 54.2) log10 ribonucleic acid (RNA) copies. Young age (<1 year), presence of upper respiratory symptoms, intra-household acquisition of infection, an individual’s first infection episode in the RSV season, and having a co-infection of RSV group A and B were associated with increased amount of virus shed.

Conclusions: The findings provide insight into which groups of individuals have higher potential for transmission, information which may be useful in designing RSV prevention strategies.
Optimal Dynamic Risk Taking
Authors: Subramanian Ajay , Yang Baozhong
Published: December 2016

We analyze a continuous-time stochastic control problem that arises in the study of several important issues in financial economics. An agent controls the drift and volatility of a diffusion output process by dynamically selecting one of an arbitrary (but finite) number of projects and the termination time. The optimal policy depends on the projects’ risk-adjusted drifts that are determined by their drifts, volatilities, and the curvature (or relative risk aversion) of the agent’s payoff function. We prove that the optimal policy only selects projects in the spanning subset. Furthermore, if the projects’ risk-adjusted drifts are consistently ordered for all output values, then the optimal policy is characterized by at most K − 1 switching triggers, where K is the number of projects in the spanning subset. We also characterize the optimal policy when the consistent ordering condition does not hold, and we outline a general and tractable computational algorithm to derive the optimal policies.

Effects of platelet-rich plasma and triamcinolone acetonide on interleukin-1ß-stimulated human rotator cuff-derived cells
Authors: Muto T. , Kokubu T. , Mifune Y. , Inui A. , Sakata R. , Harada Y. , Takase F. , Kurosaka M.
Published: December 2016

Objectives

Triamcinolone acetonide (TA) is widely used for the treatment of rotator cuff injury because of its anti-inflammatory properties. However, TA can also produce deleterious effects such as tendon degeneration or rupture. These harmful effects could be prevented by the addition of platelet-rich plasma (PRP), however, the anti-inflammatory and anti-degenerative effects of the combined use of TA and PRP have not yet been made clear. The objective of this study was to determine how the combination of TA and PRP might influence the inflammation and degeneration of the rotator cuff by examining rotator cuff-derived cells induced by interleukin (IL)-1ß.

Methods

Rotator cuff-derived cells were seeded under inflammatory stimulation conditions (with serum-free medium with 1 ng/ml IL-1ß for three hours), and then cultured in different media: serum-free (control group), serum-free + TA (0.1mg/ml) (TA group), serum-free + 10% PRP (PRP group), and serum-free + TA (0.1mg/ml) + 10% PRP (TA+PRP group). Cell morphology, cell viability, and expression of inflammatory and degenerative mediators were assessed.

Results

Exposure to TA significantly decreased cell viability and changed the cell morphology; these effects were prevented by the simultaneous administration of PRP. Compared with the control group, expression levels of inflammatory genes and reactive oxygen species production were reduced in the TA, PRP, and TA+PRP groups. PRP significantly decreased the expression levels of degenerative marker genes.

Conclusions

The combination of TA plus PRP exerts anti-inflammatory and anti-degenerative effects on rotator cuff-derived cells stimulated by IL-1ß. This combination has the potential to relieve the symptoms of rotator cuff injury. Cite this article: T. Muto, T. Kokubu, Y. Mifune, A. Inui, R. Sakata, Y. Harada, F. Takase, M. Kurosaka.

Decrease of Serum IGF-I following Transsphenoidal Pituitary Surgery for Acromegaly
Authors: Yu Min , Bruns David E , Jane John A , Nass Ralf M , Oldfield Edward H , Vance Mary Lee , Thorner Michael O
Published: December 2016

BACKGROUND

In the immediate postoperative period following resection of growth hormone (GH)-secreting pituitary tumors, serum concentrations of GH have limited ability to predict remission of acromegaly. Since many actions of GH actions are mediated by insulin-like growth factor-1 (IGF-I), we aimed to determine the rates of fall of IGF-I during 72 h after surgical resection of pituitary tumors.

METHODS

We studied patients who were undergoing pituitary surgery for acromegaly. IGF-I was measured by LC-MS and GH by immunoassay. Remission was defined by the combination of serum GH <0.4 ng/mL during oral glucose tolerance testing performed 8 weeks after the surgical procedure and normal IGF-I at ≥8 weeks.

RESULTS

During the first 72 h after surgery, the mean (SD) rate of decline of IGF-I was 185 (61) ng/mL per 24 h in those who achieved remission (n = 23), with a mean (SD) apparent half-life of 55 (19) h. IGF-I had decreased to <65% of the preoperative IGF-I on postoperative day 2 in 20 of 23 remission patients (87%) vs none of 5 patients who did not achieve remission. GH was <2.7 ng/mL on day 2 in 21 of 23 remission patients (91%), but in none of the nonremission patients. The combination of IGF-I and GH on day 2 separated the remission and nonremission groups of patients.

CONCLUSIONS

Rapid decline of serum IGF-I during the immediate postoperative period warrants further study as an analytically independent adjunct to GH measurement for early prediction of biochemical remission of acromegaly.

Arte cubano contra la homofobia: Corpus frágile, una poética de resistencia
Authors: Tejo Veloso Carlos
Published: December 2016

El presente artículo analiza la serie titulada Corpus frágile del artista cubano Eduardo Hernández Santos (La Habana, 1966). Este trabajo nos enfrenta a los fragmentos de un cuerpo alimentado por la compleja problemática que implica el hecho de ser homosexual en Cuba. Así, estas fotografías construyen un hombre que desmonta el arquetipo patriarcal de virilidad y derriba el caduco patrón masculino que la propia Revolución Cubana ha creado a lo largo de estos cincuenta y seis años de trayectoria. Estas y otras maniobras alimentan la carga ideológica de Corpus frágile para construir una personal iconografía de la resistencia.
Los contrarrevolucionarios y el islam: Un análisis del pensamiento antiislámico de Louis de Bonald
Authors: Bravo López Fernando
Published: December 2016

Los contrarrevolucionarios franceses de finales del XVIII y principios del XIX situaron a la Ilustración como objetivo principal de sus críticas. Según su punto de vista, ésta había socavado las bases religiosas sobre las que se asentaba la sociedad del Antiguo Régimen, lo que había llevado, en último término, a la Revolución. Entre los males que se achacaban a los philosophes estaba el de haber sentido una «predilección» hacia el islam, debido a su empeño por acabar con los fundamentos cristianos de la sociedad. Por ello, los contrarrevolucionarios trataron de luchar contra las «falsedades» difundidas por los ilustrados acerca del islam. En este artículo se analizarán las ideas antiislámicas de Louis de Bonald, uno de los principales pensadores contrarrevolucionarios. Se verá que, para restaurar la «verdad» contra las «falsedades» ilustradas, Bonald recurrió a la visión del islam transmitida por la tradición antiislámica cristiana; pero que, a la vez, introdujo novedades influidas, paradójicamente, por el pensamiento ilustrado. De esta forma, manteniendo intactos los fundamentos de la tradición antiislámica, introdujo novedades discursivas que ayudaron a adecuarla a un nuevo contexto, preparándola para el periodo colonial.
Presos de GRAPO en una prisión de máxima seguridad: lucha y resistencia en Herrera de la Mancha (1979-1983)
Authors: Parra Iñesta Eduardo
Published: December 2016

Los Grupos de Resistencia Antifascista Primero de Octubre, GRAPO, fueron uno de los trágicos protagonistas de la Transición. Nacidos como un partido a la izquierda del Partido Comunista de España, el PCE (r), terminaron desarrollando un brazo armado a partir de 1975. Con las consecuentes detenciones fruto de su actividad, la historia de GRAPO se empezó a escribir desde la cárcel, sobre todo a partir de 1978. En este artículo nos centramos en la experiencia de los presos de esta organización en la cárcel de Herrera de la Mancha, primera cárcel de máxima seguridad construida en el Estado. Fueron llevados allí en 1979 por un castigo, la fuga de cinco compañeros de la prisión de Zamora, y en el penal manchego vivieron una experiencia marcada por la lucha y la resistencia contra el sistema penitenciario, como en la huelga de hambre de 1981 en la que uno de sus miembros murió.
El candado del 78: Podemos ante la memoria y la historiografía sobre la ruptura democrática
Authors: Rueda Laffond José Carlos
Published: December 2016

Este trabajo se aproxima al uso público de la historia en el discurso político y a las pugnas de memoria sobre la Transición española. Centra su estudio en el partido político Podemos. Como hipótesis fundamental plantea que su estrategia discursiva se caracterizó durante su proceso de creación y maduración durante 2014 por una apropiación y actualización populista de la categoría histórica de «ruptura democrática». Dicho término proviene del vocabulario de la oposición antifranquista de mediados de los años setenta. Esta progresiva recuperación y actualización fue fruto de una multiplicidad de factores donde incidieron la reflexión historiográfica, las revisiones del relato político o ciertas dinámicas de transmisión generacional donde participó la memoria militante. Desde ese supuesto, el artículo aborda diversas narrativas formuladas desde Podemos interpretándolas como prácticas de contra-memoria, en relación con el diseño de sus señas de identidad y su diagnóstico político.

La necrópolis de Orriols (Valencia): ejemplos de ritual funerario en época romana (siglos II-IV d. C)
Authors: Martínez Pérez María Asunción
Published: December 2016

La necrópolis de la barriada de Orriols (Valencia) se levanta sobre una pequeña elevación del terreno en relación con la Vía Augusta. Se trata de un cementerio periurbano que estuvo en uso entre los siglos II y IV d. C. Los enterramientos responden a los rituales de cremación e inhumación, lo que nos ha permitido constatar dos fases cronológicas durante las que se emplean otras prácticas funerarias. Además, los materiales estudiados se corresponden con las distintas fases que atravesaba el difunto, incluso después de ser enterrado.
La arquitectura doméstica urbana de las ciudades occidentales del Conventus Hispalensis: un ejercicio de crítica historiográfica
Authors: Corrales Álvarez Álvaro , Bermejo Meléndez Javier , Campos Carrasco Juan Manuel
Published: December 2016

La arquitectura doméstica de las ciudades occidentales del Conventus Hispalensis continúa siendo una línea de investigación abierta y aún por desarrollar. Así, a pesar de que existe una literatura arqueológica previa, hasta la fecha, no se había realizado un estudio que presentara una panorámica global que integrara el análisis de su arquitectura, programa ornamental, cultura material y su inserción en la trama urbana, factores explicativos de gran interés en la actualidad, a tenor del desarrollo que la arquitectura doméstica en Hispania ha sido objeto en las últimas décadas (Corrales, 2012, 256). Así, pues, se hacía necesaria la generación de un marco de trabajo teórico (Wallace– Hadrill, 1997, 219) mediante el cual, la edilicia doméstica de las ciudades del territorio onubense se entendiese como una reflexión global, en la que, de la mano de las nuevas evidencias arqueológicas, se pudiera producir una aproximación interpretativa renovada.
Ecclesiae ilicitanae, qui et eiotanae, episcopus. Sobre la extensión y dualidad de la sede episcopal de Ilici en la Antigüedad tardía
Authors: Lorenzo de San Román Roberto
Published: December 2016

En el siglo VII, en diferentes concilios de Toledo se mencionan unos obispos ilicitanos que también lo son de otra sede, Eio/Elo, surgida en el contexto del conflicto grecogótico. Siguiendo la propuesta de localización de dicha ciudad en El Tolmo de Minateda (Hellín, Albacete) se plantea aquí la dualidad Ilici+Eio como resultado de una mayor antigüedad y tradición de la sede ilicitana, con un posible obispo Juan coetáneo del Papa Hormisda a principios del siglo VI, y se utiliza dicha identificación para proponer una gran extensión del territorio de Ilici en la Antigüedad tardía.
On an asymmetric extension of multivariate
Archimedean copulas based on quadratic
form
Authors: Di Bernardino Elena , Rullière Didier
Published: December 2016

An important topic in Quantitative Risk Management concerns the modeling of dependence among
risk sources and in this regard Archimedean copulas appear to be very useful. However, they exhibit symmetry,
which is not always consistent with patterns observed in real world data. We investigate extensions
of the Archimedean copula family that make it possible to deal with asymmetry. Our extension is based on
the observation that when applied to the copula the inverse function of the generator of an Archimedean
copula can be expressed as a linear form of generator inverses. We propose to add a distortion term to this
linear part, which leads to asymmetric copulas. Parameters of this new class of copulas are grouped within
a matrix, thus facilitating some usual applications as level curve determination or estimation. Some choices
such as sub-model stability help associating each parameter to one bivariate projection of the copula. We
also give some admissibility conditions for the considered copulas. We propose different examples as some
natural multivariate extensions of Farlie-Gumbel-Morgenstern or Gumbel-Barnett.
Robustness regions for measures of risk
aggregation
Authors: Pesenti Silvana M. , Millossovich Pietro , Tsanakas Andreas
Published: December 2016

One of risk measures’ key purposes is to consistently rank and distinguish between different risk
profiles. From a practical perspective, a risk measure should also be robust, that is, insensitive to small perturbations
in input assumptions. It is known in the literature [14, 39], that strong assumptions on the risk
measure’s ability to distinguish between risks may lead to a lack of robustness. We address the trade-off between
robustness and consistent risk ranking by specifying the regions in the space of distribution functions,
where law-invariant convex risk measures are indeed robust. Examples include the set of random variables
with bounded second moment and those that are less volatile (in convex order) than random variables in a
given uniformly integrable set. Typically, a risk measure is evaluated on the output of an aggregation function
defined on a set of random input vectors. Extending the definition of robustness to this setting, we find
that law-invariant convex risk measures are robust for any aggregation function that satisfies a linear growth
condition in the tail, provided that the set of possible marginals is uniformly integrable. Thus, we obtain that
all law-invariant convex risk measures possess the aggregation-robustness property introduced by [26] and
further studied by [40]. This is in contrast to the widely-used, non-convex, risk measure Value-at-Risk, whose
robustness in a risk aggregation context requires restricting the possible dependence structures of the input
vectors.
VaR bounds for joint portfolios with
dependence constraints
Authors: Puccetti Giovanni , Rüschendorf Ludger , Manko Dennis
Published: December 2016

Based on a novel extension of classical Hoeffding-Fréchet bounds, we provide an upper VaR bound
for joint risk portfolios with fixed marginal distributions and positive dependence information. The positive
dependence information can be assumed to hold in the tails, in some central part, or on a general subset of
the domain of the distribution function of a risk portfolio. The newly provided VaR bound can be interpreted
as a comonotonic VaR computed at a distorted confidence level and its quality is illustrated in a series of
examples of practical interest.
Crowdfunding: Motives, Definitions, Typology and Ethical Challenges
Authors: Hossain Mokter , Oparaocha Gospel Onyema
Published: December 2016

Crowdfunding is an emerging phenomenon that has attracted significant interest from scholars and practitioners alike, mainly due to its appeal as an alternative source of funding. As crowdfunding has grown exponentially, so have the associated challenges and opportunities. In this conceptual paper, we define crowdfunding; discuss its characteristics, related terminologies, key elements and ethical issues. We also propose a typology for crowdfunding and indicate various issues associated with it. The final section includes the implications of this study and suggestions for future research. This paper aims to inspire a scholarly debate and further develop the theoretical foundation of the crowdfunding literature. This may also prompt practitioners to take note of the emerging concerns as the crowdfunding phenomenon is transforming from a marginal to a mainstream discipline.

Piecewise synergetic systems and applications in biochemical systems theory
Authors: Ponosov Arcady , Machina Anna , Tafintseva Valeria
Published: December 2016

We study piecewise synergetic systems originating from Biochemical Systems Theory. In the first part of the paper, the emphasis is put on practical calculations with such systems. We consider four examples: calculation of trajectories and steady states, solution of an optimization problem and a method of estimation of parameters (kinetic orders), all examples being biologically motivated. In the second part of the paper, we study convergence of solutions, in particularly, steady states, of a sequence of piecewise synergetic systems approximating an arbitrary compartment model. This convergence analysis is then applied to the optimization problem and the method of estimating sensitivities (kinetic orders) in a generic compartment model. In this paper we put forward arguments for the importance of the theoretical and numerical analysis of piecewise synergetic systems.
The Economic Value of Book Loans – The Case of the Municipal Library of Prague
Authors: Stejskal Jan , Hájek Petr , Rehak Tomas
Published: December 2016

In recent years, the value of public library services has tended to be evaluated using the contingent valuation method. This is able to reveal readers’ hidden preferences. However, it appears that the total value of a public library as expressed by one number leads to a methodological bias related to the difficulty of assessing the value of one standard book loan. Moreover, this approach does not reflect the needs of public libraries’ management. Therefore, this study focuses on a detailed investigation of the most important public library service, book loans. For this purpose, we have employed statistical models to identify the significant determinants of willingness to pay (WTP) for book loans and WTP for purchasing books, respectively. The results suggest that loan services have the greatest perceived value for students, people who are economically active. Management who are interested in increasing the success of their institution across society must also know the perceived value of individual books so that they can adjust their library's acquisition policy. It was found that novels had the highest perceived value, followed by educational literature in the fields of economics and education as well as information science. This entirely new analytical method of measuring WTP for public services raises many new implications that could change the strategies of individual libraries – as well as the public policy strategies of donors and library ownership.
Machine learning for metagenomics: methods and tools
Authors: Soueidan Hayssam , Nikolski Macha
Published: December 2016

Owing to the complexity and variability of metagenomic studies, modern machine learning approaches have seen increased usage to answer a variety of question encompassing the full range of metagenomic NGS data analysis.We review here the contribution of machine learning techniques for the field of metagenomics, by presenting known successful approaches in a unified framework. This review focuses on five important metagenomic problems:OTU-clustering, binning, taxonomic proffiing and assignment, comparative metagenomics and gene prediction. For each of these problems, we identify the most prominent methods, summarize the machine learning approaches used and put them into perspective of similar methods.We conclude our review looking further ahead at the challenge posed by the analysis of interactions within microbial communities and different environments, in a field one could call “integrative metagenomics”.
Corrosion and mechanical properties of AM50 magnesium alloy after modified by different amounts of rare earth element Gadolinium
Authors: Yang Miao , Zhang Zhiyi , Liu Yaohui , Han Xianlong
Published: December 2016

To improve the corrosion and mechanical properties of the AM50 magnesium alloy, different amounts of the rare earth element gadolinium were used. The microstructure, corrosion and mechanical properties were evaluated by X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, and electrochemical and mechanical stretch methods. The results indicate that, with Gd addition, the amount of the Al2Gd3 phase increased while the β-Mg17Al12 phase amount decreased. Due to the Gd addition, the grain of the AM50 magnesium alloy was significantly refined, which improved its tensile strength. Further, the decrease in the amount of the β phase improved the corrosion resistance of the alloy. The fracture mechanism of the Gd-modified AM50 magnesium alloy was a quasi-cleavage fracture. Finally, the optimum corrosion residual strength of the AM50 magnesium alloy occurred with 1 wt.%of added Gd.
