Influence of varying the input parameters on the results of model validation
Authors: Götz Gernoth , Polach Oldrich
Published: May 2017

This article presents an evaluation of the model validation method that was provided as the output of the European research project DynoTRAIN and implemented in the recently revised European standard EN 14363. The input parameters of the validation method, namely the section length, number, and selection of sections as well as the selected parameters of the simulation models are varied. The evaluation shows that a single section that provides a large deviation between simulation and measurement can, in rare cases, influence the results of the overall validation. Nevertheless, the investigations demonstrate a good robustness, as the final validation result is very rarely influenced by the variation of sections selected for validation, by the use of a higher number of sections than the minimum of 12, or by longer sections than that specified for on-track tests in accordance with EN 14363. The validation methodology is also able to recognize the errors in vehicle model parameters, if the errors have a relevant influence on the behaviour of the running dynamics of the evaluated vehicle.
Distinct Motivational Effects of Contingent and Noncontingent Rewards
Authors: Manohar Sanjay G. , Finzi Rebecca Dawn , Drew Daniel , Husain Masud
Published: May 2017

When rewards are available, people expend more energy, increasing their motivational vigor. In theory, incentives might drive behavior for two distinct reasons: First, they increase expected reward; second, they increase the difference in subjective value between successful and unsuccessful performance, which increases contingency—the degree to which action determines outcome. Previous studies of motivational vigor have never compared these directly. Here, we indexed motivational vigor by measuring the speed of eye movements toward a target after participants heard a cue indicating how outcomes would be determined. Eye movements were faster when the cue indicated that monetary rewards would be contingent on performance than when the cue indicated that rewards would be random. But even when the cue indicated that a reward was guaranteed regardless of speed, movement was still faster than when no reward was available. Motivation by contingent and certain rewards was uncorrelated across individuals, which suggests that there are two separable, independent components of motivation. Contingent motivation generated autonomic arousal, and unlike noncontingent motivation, was effective with penalties as well as rewards.
A gap time model based on a multiplicative marginal rate function that accounts for zero-recurrence units
Authors: Louzada Francisco , Macera Márcia AC , Cancho Vicente G
Published: May 2017

In this article, we propose an alternative gap time model based on a multiplicative marginal rate function, which is formulated considering each gap time conditional on the previous recurrence times. In this formulation, the gap times are treated equally and the relation between successive events is no longer a problem. Furthermore, this article considers the inclusion of a proportion of zero-recurrence units (for which the event of interest will not occur) into the model to analyze recurrent event data. Inference aspects of the proposed model are discussed through maximum likelihood approach. A simulation study is carried out to examine the performance of the estimation procedure. The model is applied to hospital readmission data among colorectal cancer patients.
Determination of BRAF V600E (VE1) protein expression and BRAF gene mutation status in codon 600 in borderline and low-grade ovarian cancers
Authors: Sadlecki Pawel , Walentowicz Pawel , Bodnar Magdalena , Marszalek Andrzej , Grabiec Marek , Walentowicz-Sadlecka Malgorzata
Published: May 2017

Epithelial ovarian tumors are a group of morphologically and genetically heterogeneous neoplasms. Based on differences in clinical phenotype and genetic background, ovarian neoplasms are classified as low-grade and high-grade tumor. Borderline ovarian tumors represent approximately 10%–20% of all epithelial ovarian masses. Various histological subtypes of ovarian malignancies differ in terms of their risk factor profiles, precursor lesions, clinical course, patterns of spread, molecular genetics, response to conventional chemotherapy, and prognosis. The most frequent genetic aberrations found in low-grade serous ovarian carcinomas and serous borderline tumors, as well as in mucinous cancers, are mutations in BRAF and KRAS genes. The most commonly observed BRAF mutation is substitution of glutamic acid for valine in codon 600 (V600E) in exon 15. The primary aim of this study was to determine whether fully integrated, real-time polymerase chain reaction–based Idylla™ system may be useful in determination of BRAF gene mutation status in codon 600 in patients with borderline ovarian tumors and low-grade ovarian carcinomas. The study included tissue specimens from 42 patients with histopathologically verified ovarian masses, who were operated on at the Department of Obstetrics and Gynecology, Nicolaus Copernicus University Collegium Medicum in Bydgoszcz (Poland). Based on histopathological examination of surgical specimens, 35 lesions were classified as low-grade ovarian carcinomas, and 7 as borderline ovarian tumors. Specimens with expression of BRAF V600E (VE1) protein were tested for mutations in codon 600 of the BRAF gene, using an automated molecular diagnostics platform Idylla™. Cytoplasmic immunoexpression of BRAF V600E (VE1) protein was found in three specimens: serous superficial papilloma, serous papillary cystadenoma of borderline malignancy, and partially proliferative serous cystadenoma. All specimens with the expression of BRAF V600E (VE1) protein were tested positively for BRAF V600E/E2/D mutation. No statistically significant relationship (p > 0.05) was found between the presence of BRAF V600E mutation and the probability of 5-year survival. BRAF mutation testing with a rapid, fully integrated molecular diagnostics system Idylla™ may be also a powerful prognostic tool in subjects with newly diagnosed serous borderline tumors, identifying a subset of patients who are unlikely to progress.

Introduction. This retrospective study examined the role of aortic valve (AV) disease in patients who underwent orthotopic liver transplantation (OLT) to determine the incidence of postoperative cardiac morbidity and mortality when compared with a matched control group without AV disease. Methods. Patients were included in the AV group if diagnosed with aortic stenosis (AS) or aortic regurgitation or had received AV replacement prior to OLT. The AV group (n = 53) was matched to a control group (n = 212) with the following preoperative variables: type of organ transplanted, age, gender, race, body mass index, MELD, redo-transplantation, preoperative renal replacement therapy, nonalcoholic steatohepatitis, viral hepatitis, diabetes, and coronary artery disease. A 1:4 ratio was utilized to improve the efficiency and power of the analysis. Results. No significant difference in survival or posttransplant cardiac complications (acute coronary syndrome, heart failure, or dysrhythmia) was observed between groups. However, statistically significantly more patients—11% (6/53)—required coronary intervention following OLT in the AV group, whereas 3% (7/212) required coronary intervention (χ2 = 5.8; P = .0156) in the control group. Following OLT, 9% (5/53) in the AV group required surgical or nonsurgical AV intervention, whereas no valvular events were observed in the control group. Event-free survival in the AV group, with an end point defined as AV intervention (n = 5) and death (n = 10), was 92% (49/53) at 1 year, 83% (44/53) at 3 years, and 72% (38/53) at 5 years. Conclusions. Patients with pretransplant AV replacement or AS have significant cardiac complications (myocardial infarction, AV replacement, or cardiac death) in 1 to 3 years post-OLT.
Time-Based Switching Control of Genetic Regulatory Networks: Toward Sequential Drug Intake for Cancer Therapy
Authors: Oduola Wasiu Opeyemi , Li Xiangfang , Duan Chang , Qian Lijun , Wu Fen , Dougherty Edward R
Published: May 2017

As cancer growth and development typically involves multiple genes and pathways, combination therapy has been touted as the standard of care in the treatment of cancer. However, drug toxicity becomes a major concern whenever a patient takes 2 or more drugs simultaneously at the maximum tolerable dosage. A potential solution would be administering the drugs in a sequential or alternating manner rather than concurrently. This study therefore examines the feasibility of such an approach from a switched system control perspective. Particularly, we study how genetic regulatory systems respond to sequential (switched) drug inputs using the time-based switching mechanism. The design of the time-driven drug switching function guarantees the stability of the genetic regulatory system and the repression of the diseased genes. Simulation results using proof-of-concept models and the proliferation and survival pathways with sequential drug inputs show the effectiveness of the proposed approach.
Diamonds are a girl’s best friend …? Examining gender and careers in the jewellery industry
Authors: Duberley Joanne , Carrigan Marylyn , Ferreira Jennifer , Bosangit Carmela
Published: May 2017

Using Acker’s concept of ‘inequality regimes’, this article examines the practices and processes of gender inequality in the Birmingham Jewellery Quarter, highlighting the complex and subtle nature of discrimination sometimes at play and the strategies used by those who progress within this context. The project involved in-depth interviews during which participants recounted their career stories. Our research study examines the ways in which men and women in the Birmingham Jewellery Quarter account for their careers in order to examine the underlying gender regimes that influence the everyday practices of workers in this context. Our findings suggest that contrary to contemporary images of the creative industries, jewellery making remains deeply traditional with structures and processes that both overtly and covertly disadvantage women workers. Empirically, this article enhances our understanding of the way that this creative cluster operates and examines how that disadvantages particular groups of workers. Theoretically, this article contributes to our knowledge of the use of the concept of gender regimes at a cluster level.
Analysing decisions on diversity and opportunity in the cultural and creative industries: A new framework
Authors: Ruth Eikhof Doris
Published: May 2017

This article proposes a new conceptual framework for analysing diversity and opportunity in the cultural and creative industries as outcomes of specific decisions. It suggests the following three analytical foci: (1) the points at which decisions influence an individual’s opportunities for workforce participation and advancement; (2) individual workers as objects of decisions, in particular with respect to (a) an individual’s likelihood of being considered in a particular decision process in the first place and (b) what individuals present for decision makers to decide upon; and (3) the decision makers and the context of their decision making. Using this conceptual framework, this article reviews and synthesises existing evidence from academic and industry research to ascertain what is currently understood about the factors that influence decisions about workforce participation, promotion and admission into higher education, and which research gaps remain. By focusing on decisions, this article transcends current analysis of diversity and opportunity in the cultural and creative industries, which is largely concerned with how social and economic capital intersects with work and employment practices to shape workers’ opportunities. The article argues that a decision-making focus enables an important shift of perspective for understanding diversity and opportunity in the cultural and creative industries and how they might be improved.
“Our teachers and the limits of cognition”: Dietzgen and the challenge of McLaren’s epistemology
Authors: Boxley Simon
Published: May 2017

In Peter McLaren’s words “We need a philosophically grounded alternative to capitalism”, but what does such a philosophical grounding look like? Need it be shared? The philosophical basis for practice was not shared by Lenin and Bogdanov, for example, and yet both retained the ability to work together in the Bolshevik party. There’s a profound difference between god-building, and god-seeking. Socialists have strong traditions of both. Peter McLaren’s recent work fits into the latter category. I will engage with this project, because I think Peter’s position, whilst honourable, lacks the visionary power of the former. And to these I would like to add a third position, one which seeks to extend to all of the material universe and to all living things a sacred character, but without any requirement for categories such as god. There are of course many mystic traditions which espouse something similar, but relatively few socialists have developed politically this position, as espoused by the tanner-philosopher Josef Dietzgen (though there are certainly close links between Dietzgenism and god-building). My argument for raising such seemingly arcane concerns, is rather similar to that of Lenin whose immersion in philosophy in writing Materialism and Empirio-Criticism primarily met the political requirements of the day. Amidst ubiquitous talk of the Anthropocene, and a sudden rise in interest in Bogdanov on the Marxist left, now is the moment to look to the prospect of taking up a Bogdanovite project, not to build a new god, but to re-sacralise nature. In this paper, I begin to mobilise an unlikely alliance around this vision: not only Dietzgen, but deep ecologists and even Jiddu Krishnamurti assist in exploring the limitations of McLaren’s position.
An Investigation Into Facebook “Liking” Behavior An Exploratory Study
Authors: Ozanne Marie , Cueva Navas Ana , Mattila Anna S. , Van Hoof Hubert B.
Published: May 2017

This article reports on a study that explored users’ motives in using the Like feature on Facebook. Data were collected by means of in-depth interviews of daily Facebook users in two distinct cultures, the United States and Ecuador. The findings of the study reveal that the Like may be used (1) to acknowledge the gratifications obtained with the use of Facebook, (2) to share information with others, and (3) as a tool for impression management. Four categories of gratified usage motives influencing Liking behavior with distinctly different preferences in each culture, were found. The four categories that gratified usage motives are entertainment, information/discovery, bounding, and self-identification. Three types of underlying motives dominated the use of the Like to share information: presentation of the self, presentation of the extended-self, and social obligations. Finally, the Like can be used as a self-protective tool for impression management. The present findings lay the foundation for a grounded theory model that may guide future research efforts in this area.
Imaging Diagnosis of a Rare Presacral Tumour
Authors: Grover Hemal , Ahluwalia Amrit Pal , Sethi Sanjay
Published: May 2017

Background: Primary tumors in the presacral (retrorectal) space are extremely rare in adults, with an estimated incidence of 0.0025 to 0.014 in large referral centers. Congenital varieties are most common and comprise two thirds of these tumors. Primary retroperitoneal sarcomas in the pelvic region are extremely rare. We report the ultrasound and the corresponding Computed Tomography (CT) features of a rare presacral fibrosarcoma in an adult woman, in whom the diagnosis was confirmed by a CT-guided biopsy.

Case Report: A 54-year-old woman presented with a history of lumbar and perineal pain and painful defecation. Rectal examination revealed a hard mass in the retrorectal space. The patient was referred for imaging and a laboratory evaluation with a clinical diagnosis of a presacral mass. An abdominal ultrasound was followed by laboratory evaluation of routine hematological and hepato-renal parameters, abdomino-pelvic CT and a CT-guided biopsy. The imaging studies showed a presacral solid mass with nodular calcifications. There was conspicuous absence of cystic or adipose contents and of sacral erosion/destruction. However, hepatic metastasis was present.All imaging features suggested a retroperitoneal sarcoma in the pelvic region with metastases to the liver. The diagnosis was confirmed by CT-guided biopsy.

Conclusions: We are reporting a new case of a very rare entity, a presacral fibrosarcoma. The imaging approach and the analysis leading to an appropriate differential diagnosis and final diagnosis is highlighted in our case report.
Forecasting Corporate Bond Returns with a Large Set of Predictors: An Iterated Combination Approach
Authors: Lin Hai , Wu Chunchi , Zhou Guofu
Published: May 2017

Using a comprehensive return data set and an array of 27 macroeconomic, stock, and bond predictors, we find that corporate bond returns are highly predictable based on an iterated combination model. The large set of predictors outperforms traditional predictors substantially, and predictability generated by the iterated combination is both statistically and economically significant. Stock market and macroeconomic variables play an important role in forming expected bond returns. Return forecasts are closely linked to the evolution of real economy. Corporate bond premia have strong predictive power for business cycle, and the primary source of this predictive power is from the low-grade bond premium.

Orthogonal Representations, Projective Rank, and Fractional Minimum Positive Semidefinite Rank: Connections and New Directions
Authors: Hogben Leslie , Palmowski Kevin , Roberson David , Severini Simone
Published: May 2017

Fractional minimum positive semidefinite rank is defined from r-fold faithful orthogonal representations and it is shown that the projective rank of any graph equals the fractional minimum positive semidefinite rank of its complement. An r-fold version of the traditional definition of minimum positive semidefinite rank of a graph using Hermitian matrices that fit the graph is also presented. This paper also introduces r-fold orthogonal representations of graphs and formalizes the understanding of projective rank as fractional orthogonal rank. Connections of these concepts to quantum theory, including Tsirelson's problem, are discussed.
The FRAP assay: Allowing students to assess the anti-oxidizing ability of green tea and more
Authors: Ring Justine , Chaung Michelle
Published: May 2017

Dietary sources of polyphenols receive significant public attention due to their many toted health benefits and speculated preventative medical applications. This stems from the reducing ability of polyphenolic compounds as it has been previously established that total reducing capacity can be linearly correlated to the antioxidant power of a material1. While undergraduate students are possibly aware of the potential benefits of antioxidants compounds found naturally in materials such as green teas and berries, they may not have yet considered the chemical mechanism of how these natural antioxidants function. Although the chemical mechanism by which natural materials act as antioxidants varies, many use polyphenol structures to perform these redox reactions2. Therefore, the antioxidizing power of various materials such as green tea leaves, coffee beans, and berries can be compared by quantifying the concentration of polyphenols in these materials3. Here, we have developed an experiment in which undergraduate organic chemistry students will use the “Ferric Reducing Ability of Plasma” assay (FRAP) to directly measure the reducing capacity of green tea leaves, and thus infer the antioxidant potential of natural antioxidants from dietary sources4. This experiment thus helps students gain an appreciation for the relevance and diversity of electrochemical reactions in natural materials, as well as introduces them to Green Chemistry principles. Students will use the FRAP assay to assess the viability of safe, natural, reducing agents4, which provide the potential to limit the use of more hazardous, environmentally damaging reducing agents) used in industry today
Building a Better Battery: Ionic Conductivity of Granular Hydrate Crystals
Authors: Jian Tiger (Haozhe)
Published: May 2017

Although solid state batteries are an alternative to conventional batteries, they generally produce low power due to their poor ionic conductivity. This study tested the ionic conductivities of powdered potassium sodium tartrate and potassium aluminum sulfate, two double salts that have garnered attention as potential solid state electrolytes. The substances were hypothesized on having abnormally high conductivities. Conductivity was measured using electrical impedance spectroscopy on an Arduino UNO. The results indicated that the double salts had indeed high conductivities for an ionic crystal at 5.6e-5±6e-6 S/m for PST and 7.8e-6±9e-7 S/m for PAS. However, the other 3 materials tested all produced similar values. Furthermore, one of the materials tested, sodium chloride, has a documented conductivity of 10-12 S/m. The high conductivities as well as the discrepancy between the measured and documented conductivities of sodium chloride were attributed to the powder form of the materials. Caking may have occurred and increased conductivity by increasing defect concentration as well as by creating moisture channels through which free ions could flow. These results have vast implications if a powdered electrolyte material may be successfully applied to existing fast ion conductors instead of insulators such as sodium chloride.

Heat Vision: Superman or Pit-Bearing Snakes?
Authors: Baek Jason
Published: May 2017

When one reads the words ”heat vision,” it is common to imagine Superman flying through the air, blasting red beams from his eye sockets. Although this is a fairly creative image, the type of “heat vision” found in many snakes is different. When alluding to “heat vision” in snakes, one refers to the ability of certain snake species to sense heat through pit organs. These structures connect with a snake’s sense of touch, with the trigeminal nerves and ganglia being major components of this mechanism. Transient receptor potential cation channel, member A1, or PRTA1, is a protein found in the stems of trigeminal nerves. It is often asserted that the evolution of PRTA1 is directly connected to the evolution of infrared sensory pitbearing snakes. Quand une personne lit les mots ”vision de chaleur,” il est naturel que la première chose qui vient a tête est l’image de Superman qui vole dans le ciel avec des rayons rouges quit sortes de ses yeux. Bien que ceci est une image créative, le type de “vision de chaleur” qui se trouve dans les serpents est très différent. Lorsqu’on parle de “vision de chaleur” dans les serpents souvent on réfère à l’abilité que l’èspece de serpent peut sentir la chaleur à travers de ses organes. Ces structures on des connections avec le sens du toucher d’un serpent, avec les nerves trijumeau et le ganglion qui sont des composants major de cette méchanism. Le canal cationique potentiel de récepteur transitoire, membre A1, ou PRTA1, est un protéin qui se trouve dans les tuyaux des nerves trijumeau. Il est souvent affirmé que l’évolution du PRTA1 est directement connecté à l’évolution des serpents de puits avec sensorielle infrarouge.
Introducing the Arts and Science Section
Authors: Lam Adela , Yan Cathy
Published: May 2017

The Science and arts are commonly considered to be two vastly different disciplines contrasting each other primarily in terms of methodology. The sciences value precision and the ability to control and replicate results, while arts stem from the fluid and unique expression of one’s self using different mediums. However, despite these characteristics, the ultimate goal of both areas of study is to explore the unknown. For arts, this entails delving into human emotions through abstract thoughts and ideas, while sciences use the same abstractions and imagination to experiment with and create using objects in the natural world. This combination of internal and external explorations define the intrinsic elements of the universe, which is why arts and science belong together. Les sciences et les arts sont souvent considérés comme deux disciplines vastement différents qui se contrastent surtout en terme de méthodologie. Les sciences mettent en valeur la précision et la capacité de contrôler et répéter des résultats alors que les arts proviennent de l’expression fluide et unique de soi-même en utilisant de divers moyens. Cependant, malgré ces caractéristiques, le but ultime des deux domaines d’étude est d’explorer l’inconnu.

Análise probabilística da contaminação da água subterrânea usando métodos de confiabilidade de primeira e segunda ordem
Authors: Godoy Vanessa Almeida de , Napa-García Gian Franco
Published: May 2017

Este artigo mostra um exemplo de aplicação da estimativa da probabilidade de um contaminante exceder uma máxima concentração especificada (probabilidade de excedência, Pf), usando métodos de confiabilidade de primeira (FORM) e segunda ordem (SORM) para diversas concentrações iniciais de um soluto hipotético, sem biodegradação e tempos de análise de 5 e 10 anos, considerando-se um fluxo unidimensional em solo arenoso. A validade dos resultados foi avaliada comparando os resultados obtidos de FORM e SORM com aqueles da Simulação de Monte Carlo (SMC). Para uma mesma concentração inicial, a Pf aumentou com o aumento do tempo de análise. Para ambos os tempos de análise (5 e 10 anos) e métodos aplicados, a Pf tende a aumentar com o aumento da concentração inicial. A comparação entre os valores de Pf obtidos com FORM e SORM e com a SMC mostra que a partir de 50 μg/Lde concentração inicial a SMC e o FORM apresentam valores de Pf muito próximos. Os valores obtidos com o SORM apresentaram proximidade com aqueles resultantes da SMC apenas para as concentrações iniciais de 50 e 100 μg/L. A proximidade dos valores de Pf obtidos com SMC e FORM indicam que o uso deste método de confiabilidade é útil na obtenção da Pf, além de ser uma maneira mais rápida do que a SMC.

3D power Doppler in the evaluation of abnormally invasive placenta
Authors: Calì Giuseppe , Foti Francesca , Minneci Gabriella
Published: May 2017

The anomalies in placental insertion and invasion, such as placenta previa and the various forms of abnormally invasive placenta, are today a rising obstetric pathology. Two-dimensional (2D) ultrasonography is the gold standard in the diagnosis of abnormally invasive placenta (AIP), but the important feto-maternal impact of this pathology suggests the opportunity to employ all the available diagnostic techniques, such as three-dimensional (3D) power Doppler. This technique allows acquiring multiplanar images on coronal, axial and sagittal planes and with a rotational technique, it permits visualizing the placenta-bladder interface more accurately. Consequently, it allows a better study of the degree of bladder invasion, which is information that has a great impact on the subsequent counseling and management. Thus, 3D power Doppler represents an important technique complementary to 2D ultrasound in the diagnosis of AIP. The aim of this paper is to illustrate the possible applications of this procedure, referring to the main literature data.
Density of leopards (Panthera pardus kotiya) in Horton Plains National Park in the Central Highlands of Sri Lanka
Authors: Kittle Andrew M. , Watson Anjali C.
Published: May 2017

Quantitative ecological data needs to inform management of the endangered, endemic Sri Lankan leopard. Estimating habitat-specific leopard density and prey availability provides important baselines and improved understanding of the island-wide population. We used remote cameras in a spatially explicit capture-recapture framework to estimate leopard density (11.7 adult individuals/100 km2) and distance sampling to estimate prey density, within Horton Plains National Park. Sambar density was 178/km2 within the central grasslands, which represent a spatially anchored resource for sambar and in turn, a highly clumped, abundant resource for leopards. This study represents the first robust estimate of leopard density in Sri Lanka’s montane zone.

Collins, DK, McRobert, A, Morton, JP, O'Sullivan, D, and Doran, DA. The work-rate of elite hurling match-play. J Strength Cond Res 32(3): 805–811, 2018—This study describes the global work-rate of elite hurling match-play and the influence which positional difference has on work-rate is considered. The movement of ninety-four players was recorded using global positioning system, sampling at 4 Hz in a total of 12 games. Data were classified according to the positional line on the field and period of the match. The total and high-speed distance of match-play was 7,617 ± 1,219 m (95% confidence interval [CI], 7,367–7,866) and 1,134 ± 358 m (95% CI, 1,060–1,206), respectively. The maximum speed attained was 29.8 ± 2.3 km·h−1 with a mean speed of 6.1 ± 1 km·h−1. The second {271 ± 107 m (p = 0.001; effect size [ES] = 0.25)}, third (278 ± 118 m [p = 0.001; ES = 0.21]), and fourth quarter (255 ± 108 m [p = 0.001; ES = 0.31]) high-speed running distance differed significantly from that of the first quarter (330 ± 120 m). There was a significant difference in total (p = 0.001; ES = 0.01–0.85), high-speed running (p = 0.001; ES = 0.21–0.76), and sprint (p = 0.013; ES = 0.01–0.39) distance across the positions, with midfielders undertaking the highest volume of work, followed by the half-forward and half-back lines and finally the full-forward and full-back lines. A decrease in high-speed running distance seems to occur through out the game and in particular at the latter stages of each half. Distinct positional work profiles are evident. The present finding provide a context on which training which replicates the work-rate of match-play may be formulated, thus helping to improve the physical preparation of elite players.

Competitive crowdsourcing is a popular strategic model for solving tasks in an efficient economical way. Competitive crowdsourcing platforms generally choose the winners for a single indivisible task following the conventional Dutch auction to minimize the cost. In this paper, we show that when the tasks are decomposable such mechanisms become biased for competitive crowdsourcing markets. As a solution to this, we suggest a variant of the Dutch auction (referred to as time-invariant Dutch auction) for solving decomposable tasks. Overall, some new insights about the mechanism design for competitive crowdsourcing markets are obtained.

Los estudios sociales sobre las finanzas domésticas pueden clasificarse en dos tipos: investigaciones enfocadas al estudio de “dispositivos de mercado” (tales como scorings y tarjetas de crédito) utilizados por compañías financieras, e investigaciones que analizan las nuevas prácticas y modos de “cálculo cotidiano” desarrollados por los usuarios de los servicios financieros alrededor del mundo. Este artículo es parte de un proyecto mayor que busca abrir un camino diferente, que intenta situar a los estudios sociales de las finanzas domésticas en la intersección donde ambos tipos de cálculo los big data de los dispositivos de mercado y el small data de los cálculos financieros cotidianos–, puedan ser observados de manera conjunta. Más específicamente, este artículo discute algunos de los desafíos metodológicos enfrentados en esta nueva posición, en particular como usamos las huellas dejadas por el big data y cómo hemos lidiado con un tipo de circuito comercial inesperado.

A tool to predict environmental risk to UK rail infrastructure
Authors: Sadler Jason , Kit Oleksandr , Austin Jeremy , Griffin David
Published: May 2017

Researchers from the University of Southampton have collaborated with the rail industry's independent safety body RSSB on a pilot project for a geospatial risk model. The aim was to use the model to analyse and map derailments, suicides and slip, trip and fall risks across the UK rail network, initially in the Wessex region. The research has been extended to incorporate the impact of historic and real-time environmental data on rail risk. This paper presents a detailed description of the investigations, the resulting methodology and a prototype toolkit. The toolkit incorporates environmental conditions combined with rail incident data to help model and predict increased risk in real time.

Published: May 2017

Background. Microsporidia are ubiquitous parasites of animals, most abundant in arthropods and fishes. Many species of these parasites are important from standpoints of medicine, veterinary and agriculture. Microsporidium Nosema pyrausta is an important disease agent in corn borer populations causing adverse effect on host fitness. Genotyping of this parasite is necessary for proper species identification and intraspecific polymorphysm studies.

Materials and Methods. Microsporidia-infected larvae of corn borers of the genus Ostrinia were recovered from Krasnodar Territory in Russia and Gomel Region in Belarus. Small subunit ribosomal RNA (SSU rRNA) was amplified and sequenced directly, while intergenic spacer (IGS) was amplified, cloned and sequenced (1-5 clones per sample) for four isolates of microsporidia. Sequences were aligned and compared using standard bioinformatics tools (Clustal W and BLAST).

Results. SSU rRNA genotyping showed allocation of all four isolates to N. pyrausta with 100% identity to each other and 99.7% similarity to Nosema bombycis, the type species of the genus Nosema. High levels of IGS sequence variation (61-74%) is observed both between isolates of different species and populations of microsporidia as well as between molecular clones within parasite isolates from individual hosts.

Conclusion. N. pyrausta is widespread in corn borer populations and its genetic structure is complicated, as in other species of these parasites. Further studies of molecular markers are needed for genetic differentiation of geographic isolates of N. pyrausta.
Why urban Indians are interested in an internet based self-care app for depression? a brief pilot survey

Published: May 2017

Background: Digital technology has emerged as a powerful approach to bridge treatment gap in the field of mental health. However, public health impact of e-interventions is unlikely without large scale uptake of such services. Hence it becomes important to understand motives of potential users in order to design programs that address such needs as well as disseminate information about the same in ways that appeal to the users. Methods: Reasons underlying interest in an internet based self-care program for depression were explored through a brief survey of potential users who had explicitly shown interest in such a program. Responses to an online survey were received from 120 respondents out of which about 69% were in 18-35 years of age-range and 12% were above 50 years of age. Results: Preference for flexibility in terms of ‘when I do things to help myself’, ‘not having time to go for face to face counselling/therapy’ and ‘wanting to learn and do something to prevent problems in future even though I am currently on treatment’ emerged as the top 3 reasons underlying interest in internet based self-help programs for depression. Not having the finances to seek face to face mental health consultation emerged as one of the top 3 reasons in the older group. Conclusions: Incorporating maximal flexibility, providing pointers to the most relevant components thereby minimizing time required, and focusing on preventive strategies (even for those who are currently seeking treatment) are aspects that need to be considered in development and dissemination of internet based self-help programs for depression in urban India.

Nacionalismo e Aprendizagem no Programa de Águas Profundas da Petrobras
Authors: Furtado André Tosi , Freitas Adriana Gomes
Published: May 2017

O presente trabalho avalia os impactos econômicos resultantes de diversas formas de aprendizado que derivaram da execução de projetos tecnológicos nacionalistas. Esses projetos visavam o desenvolvimento e o domínio local de tecnologias estratégicas para o País. Toma-se como exemplo o programa de capacitação tecnológica em sistemas de produção para águas profundas da Petrobras, o Procap 1000, promovido pela Petrobras, entre 1986 e 1992. Apoiando-se em estudo anterior de avaliação dos impactos econômicos diretos e indiretos do programa (Furtado et al., 1998), foi escolhida uma amostra de sete projetos de cunho nacionalista que se caracterizam, de forma geral, por não terem sido bem-sucedidos do ponto de vista comercial. O argumento central deste trabalho consiste em que esses projetos, apesar do revés comercial, estiveram na origem de importantes processos de aprendizagem na empresa, os quais redundaram em significativos impactos econômicos indiretos. A descrição dos projetos mostra como a aprendizagem resultante do programa foi reaproveitada possibilitando a efetivação dos impactos econômicos. Os dados do estudo de avaliação de impactos econômicos da amostra de projetos do Procap 1000 revelam que os impactos econômicos superaram em mais de sete vezes os custos dos projetos. O trabalho destaca a importância da capacidade de absorção para o processo de aprendizagem. A partir de estudos de caso é proposta uma tipologia de seis formas distintas de capacidade de absorção.
R&D Intensity in the Brazilian Industry: some distributional regularities
Authors: Façanha Luís Otávio , Resende Marcelo
Published: May 2017

Resultados empíricos anteriores sobre os determinantes da intensidade em P&D têm sugerido indiretamente a relevância de competências não observadas relacionadas a P&D. Cohen e Klepper (1992) desenvolveram um modelo probabilístico que é capaz de ser consistente com fatos estilizados bem conhecidos acerca da distribuição de P&D tais como agrupamento em torno de zero, unimodalidade e assimetria positiva e gera previsões bem definidas sobre a correlação entre os diferentes momentos da distribuição (média, variância, coeficiente de variação e assimetria). A evidência para setores a 3-dígitos da indústria de transformação em São Paulo é em grande parte consistente com o referido modelo teórico.
Mudanças no Ambiente Competitivo e Novas Estratégias Tecnológicas: uma Análise Baseada nas Estatísticas de Patentes das Principais Empresas Parapetrolíferas a Partir dos Anos 1980
Authors: Iootty Mariana
Published: May 2017

O presente trabalho analisa as estratégias tecnológicas adotadas pelas empresas Baker Hughes, Halliburton e Schlumberger entre 1979 e 1998. Utilizando estatísticas calculadas a partir das patentes depositadas pelas empresas na base European Patent Office, o trabalho sugere uma mudança das estratégias tecnológicas das mesmas após o contrachoque do petróleo. Utilizando a International Patent Classification a três dígitos, as evidências empíricas indicam que após 1986 houve uma melhora significativa na performance tecnológica e na diversificação das competências tecnológicas das empresas analisadas. O presente trabalho argumenta que estas modificações tecnológicas estão relacionadas com as transformações no ambiente competitivo destas empresas, impostas pelo processo de reestruturação das majors no mesmo período.
