Streszczenie

Analiza opcji rzeczowych stanowi od lat atrakcyjną alternatywę dla podstawowej metodyki oceny efektywności ekonomicznej i wyceny aktywów rzeczowych - analizy zdyskontowanych przepływów pieniężnych DCF. Wśród zasadniczych przyczyn wzrastającego zainteresowania tą metodyką w prze­myśle - w tym w szczególności wydobywczym - jest jej potencjał w zakresie wyceny elastyczności decyzyjnej, związanej z istniejącymi faktycznie możliwościami odkładania przedsięwzięć w czasie oraz modyfikacji zakładanych pierwotnie strategii operacyjnych; takie podejście umożliwia uzys­kiwanie wartości fundamentalnej na poziomie zbliżonym do rynkowego. Fundament teorii opcji stanowi stochastyczne modelowanie zmian aktywów podstawowych tych instmmentów w czasie. Aktualnie preferowana praktyczna metodyka wyceny przedsięwzięć z elastycznością (nazywana podejściem MAD) zakłada, że walor bazowy opcji rzeczowych-wartość bieżąca brutto projektu PV - rozwija się w czasie zgodnie z iloczynowym procesem stochastycznym, stanowiącym dwumianową aproksymację geometrycznego ruchu Browna (GBM). Ponadto przyjmuje się, że instrumentem bliźniaczym aktywów podstawowych, którego istnienie jest niezbędnym warunkiem poprawnej wy­ceny opcji, jest szacowana w analizie DCF wartość zaktualizowana netto - NPV. Niniejszy artykuł dostarcza empiryczne przesłanki, że modelowanie instrumentu PV według standardowego procesu stochastycznego nie odpowiada rzeczywistości. Argumentacja przedstawiona została na przykładzie wyceny górniczego projektu inwestycyjnego z opcją czekania - metodyka obejmowała iloczynowe modelowanie ceny (walor referencyjny), a następnie budowę konsekutywnego drzewa wartości PV, kalkulowanych w wyniku adiustacji przepływów pieniężnych przedsięwzięcia instmmentem referen­cyjnym. Przy okazji zaakcentowano fakt, że walor czekania zmienia strukturę drzew przepływów i wartości bieżącej - w zależności od okresu życia tej opcji. W konkluzji dostarczono argumenty, że konsekutywne formowanie drzewa wartości bieżącej stanowi lepsze odzwierciedlenie świata realnego niż jej bezpośrednie modelowanie w podejściu MAD.

A New Adaptive Differential Protection Scheme for Tap Changing Power Transformer
Authors: Shah Ashesh Mukeshbhai , Bhalja Bhavesh
Published: June 2015

This paper presents a new adaptive differential protection scheme which efficiently adapts the change in tap position of a power transformer. The proposed scheme is based on analytical derivation of pick-up and slope of the differential relay characteristic. By acquiring information such as rating & connection of CTs and present tap position as input, the proposed scheme enhances sensitivity of differential relay during internal faults. This is accomplished either by decreasing pick-up and/or adjusting slope of the differential characteristic of the relay in case of change in tap position. Numerous test cases consisting of various types of internal and external faults have been simulated for an existing power transformer of Gujarat Energy Transmission Corporation Limited (GETCO), Gujarat, India using PSCAD/EMTDC software package. The proposed scheme increases percentage of winding to be protected during internal faults for power transformers having different ratings and connections compared to the conventional differential protection scheme. Furthermore, it has been observed that the detection sensitivity during special types of turn-to-turn and inter-winding faults with varying fault resistances is also enhanced compared to the conventional scheme. Moreover, it equally maintains stability during CT saturation condition. At the end, comparative evaluation of the proposed scheme with the existing schemes clearly indicates superiority of the proposed adaptive scheme.
Mathematical Modeling of the Discharged Heat Water Effect on the Aquatic Environment from Thermal Power Plant
Authors: Issakhov Alibek
Published: June 2015

The paper presents a mathematical model of the thermal load on the aquatic environment under operational capacity 200 MW of thermal power plant. It is solved by the Navier–Stokes and temperature equations for an incompressible fluid in a stratified medium based on numerical method, the splitting method by physical parameters which approximated the finite volume method. The numerical solution of the equation system is divided into four stages. At the first step it is assumed that the momentum transfer is carried out only by convection and diffusion. Intermediate velocity field is solved by the five-step Runge–Kutta method. At the second stage, the pressure field is solved by the intermediate velocity field. Poisson equation for the pressure field is solved by Jacobi method. The third step is assumed that the transfer is carried out only by pressure gradient. The fourth step of the transport equation for temperature is also solved as momentum equations, with five-step Runge–Kutta method. The obtained numerical results of temperature distribution for operational capacity of 200 MW of three-dimensional stratified turbulent flow were compared with experimental data, which revealed qualitatively and quantitatively approximately the basic laws of hydrothermal processes occurring in the reservoir-cooler.
A constraint-based parameterization technique for B-spline surfaces
Authors: Harmening Corinna , Neuner Hans
Published: June 2015

Deformation analysis is one of the classical tasks in engineering geodesy. The development of the laser scanner has changed the data acquisition as well as the analysis strategy; instead of point-based approaches, areal ones move into focus. In this paper, a project is presented which aims to develop a spatiotemporal continuous collocation in order to describe areal deformations.

The collocation requires among other things the modelling of a deterministic trend which is realized by the estimation of B-spline surfaces in the present study. One of the main challenges in the estimation of such freeform surfaces is the definition of an appropriate parameter form which is in the focus of this contribution. An initial parameterization is obtained by projecting the acquired point cloud onto a base surface called Coons patch. By means of a reparameterization, these initial parameters are improved iteratively. In order to handle irregular point densities, several strategies to introduce boundary constraints into the adjustment are developed, compared and evaluated.
Moderately growing solutions of third-order differential equations with a singular nonlinearity and regularly varying coefficients
Authors: Kučerová Ivana
Published: June 2015

This paper is concerned with asymptotic analysis of moderately growing solutions of the third-order differential equation with singular nonlinerity

((((x′)α₁*)′)α₂*)′ +q(t)x-β= 0;

(A) where α1, α2 and β are positive constants and σ : [α;∞)→(0;∞) is a continuous regularly varying function of index σ, α > 0 and uγ* = |u|γ sgnu. An application of the theory of regular variation allows us to establish necessary and sufficient conditions for the existence of regularly varying solutions of (A) which are moderately growing and to acquire precise information about the asymptotic behavior at infinity of these solutions. The Schauder-Tychonoff fixed point technique is used.

Successive sampling strategy under non response
Authors: Prabha Karna Jaishree , Chandra Nath Dilip
Published: June 2015

The present work is an attempt to study the effect of non-response at both occasions in search of good successive (rotation) sampling over two occasions. A chain-type ratio and regression estimator has been proposed for estimating the population mean at current occasion in presence of non-response at both the occasion in two-occasion successive (rotation) sampling. Detail behaviors of proposed estimators have been studied. Proposed estimators are compared with the estimators for the same situations but in the absence of non-response. Performances of the proposed estimators have been demonstrated via empirical studies.
Activation of insulin signaling and energy sensing network by AICAR, an AMPK activator in insulin resistant rat tissues
Authors: Radika Mutlur Krishnamoorthy , Anuradha Carani Venkatraman
Published: June 2015

Background: The energy status of the cell is regulated by the energy sensing network constituted by AMP-activated protein kinase (AMPK), the NAD+-dependent type III deacetylase silence information regulator T1 (SIRT1) and peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α). This study investigates the potential effect of 5-aminoimidazole-4-carboximide-1-b-D-ribofuranoside (AICAR), an AMPK activator on insulin signaling and energy sensing network in insulin resistant rats.

Methods: Adult male albino Wistar rats with body weight of 150–180 g were fed high-fructose diet (HFD) for 60 days to induce insulin resistance. Rats fed HFD were divided into two and were treated or untreated with AICAR (0.7 mg/kg bw, i.p.) for the last 2 weeks.

Results: Insulin resistant rats displayed increased glucose and insulin levels and reduced tyrosine phosphorylation of insulin resistance receptor and insulin receptor substrate 1. The downstream signaling and glucose transport were also affected. Phosphorylation of AMPK, SIRT1 protein abundance and mRNA expression of PGC-1α were reduced. Treatment with AICAR reduced hyperglycemia and hyperinsulinemia and improved the activation of the key molecules of insulin signaling. Improved action of energy sensing network was noted after AICAR treatment. AICAR showed higher binding affinity with Akt (−8.2 kcal/mol) than with AMPK or insulin receptor (−8.0 kcal/mol) in the in silico study.

Conclusions: The findings suggest that AICAR, the AMPK activator, influences insulin signaling proteins and molecules involved in energy modulation during insulin resistance.

Published: June 2015

Background: Fibrous structures and synthetic polymer blends offer potential usages in making biomedical devices, textiles used in medical practices, food packaging, tissue engineering, environmental applications and biomedical arena. These products are also excellent candidates for building scaffolds to grow stem cells for implantation, to make tissue engineering grafts, to make stents to open up blood vessels caused by atherosclerosis or narrowed by blood clots, for drug delivery systems for micro- to nano-medicines, for transdermal patches, and for healing of wounds and burn care. The current study was designed to evaluate the antimicrobial activity of woven and non-woven forms of nano- and macro-scale blended polymers having biocompatible and biodegradable characteristics.

Methods: The antimicrobial activity of non-woven fibrous structures created with the combination of synthetic and biopolymer was assessed using Gram-negative, Gram-positive bacteria, such as Staphylococcus aureus, Proteus vulgaris, Escherichia coli and Enterobacter aerogenes using pour plate method. Structural evaluation of the fabricated samples was performed by Fourier transform infrared spectroscopy.

Results: Broad spectrum antibacterial activities were found from the tested materials consisting of polyvinyl alcohol (PVA) with chitosan and nylon-6 combined with chitosan and formic acid.

Conclusions: The combination of PVA with chitosan was more bactericidal or bacteriostatic than that of nylon-6 combined with chitosan and formic acid. PVA combination with chitosan appears to be a broad-spectrum antimicrobial agent.
Geographic Information Systems for Disaster Response: A Review
Authors: Tomaszewski Brian , Judex Michael , Szarzynski Joerg , Radestock Christine , Wirkus Lars
Published: June 2015

Geographic Information Systems (GIS) continue to gain important recognition from disaster practitioners and academic researchers during what is arguably the most publicly visible disaster management phase – disaster response. The broader world of GIS academic research and industry practice for disaster response continues to change. This review article inventories the current state-of-the-art in GIS for disaster response and demonstrates progress in the data and people aspects of GIS for disaster response since previous literature reviews. The review is structured to serve as a metaphorical bridge between two reader groups – disaster management practitioners interested in understanding developing trends in GIS for disaster response and academic researchers with minimal to no understanding of GIS and/or mapping concepts within the disaster response context. With this readership in mind, we outline definitions of GIS, disaster response and the need for GIS in disaster response, review interdisciplinary literature from a variety of spatially-oriented disaster management fields and demonstrate progress in various aspects of GIS for disaster response. The review concludes with a GIS for disaster response research agenda and provides a list of resources for researchers new to GIS and spatial perspectives for disaster management research.
Application of the factorization method to retrieve a crack from near field data
Authors: Guo Jun , Hu Junhao , Yan Guozheng
Published: June 2015

We consider the inverse scattering problem of determining the shape of a crack with impedance boundary condition on one side from the complex conjugate of point sources placed on a closed curve which contains the crack. The near field factorization method is established to reconstruct the crack from the measurements on the same curve. Then, we deduce an inversion algorithm and present some numerical examples to show the viability of our method. So far as we know, when the incident waves are the point sources, the near field operator cannot be directly decomposed into the form that the factorization method required. However, we overcome this difficulty with the complex conjugate of point sources which are recently used in [Inverse Problems 30 (2014), Article ID 095005], [Inverse Problems 30 (2014), Article ID 045008] for the justification of the factorization method from near field data.
The Origins of Adapa
Authors: Milstein Sara J.
Published: June 2015

Antoine Cavigneaux’s (2014) recent edition of the Tell Haddad version of Adapa allows for a fresh assessment of the myth in all of its available versions. Close examination of the Tell Haddad version and the Amarna Tablet in particular reveals that the two display different sets of logic and foci, with only the latter concerned especially with Adapa and his fate. This distinction is reflective not merely of fluidity in copying but instead appears to indicate evidence of revision in the course of transmission.
Patient Portals as a Means of Information and Communication Technology Support to Patient-Centric Care Coordination – the Missing Evidence and the Challenges of Evaluation
Authors: Georgiou Andrew , Hyppönen Hannele , Ammenwerth Elske , Keizer Nicolette de , Magrabi Farah , Scott Philip , Rigby Michael
Published: June 2015

Objectives: To review the potential contribution of Information and Communication Technology (ICT) to enable patient-centric and coordinated care, and in particular to explore the role of patient portals as a developing ICT tool, to assess the available evidence, and to describe the evaluation challenges.

Methods: Reviews of IMIA, EFMI, and other initiatives, together with literature reviews.

Results: We present the progression from care coordination to care integration, and from patient-centric to person-centric approaches. We describe the different roles of ICT as an enabler of the effective presentation of information as and when needed. We focus on the patient‘s role as a co-producer of health as well as the focus and purpose of care. We discuss the need for changing organisational processes as well as the current mixed evidence regarding patient portals as a logical tool, and the reasons for this dichotomy, together with the evaluation principles supported by theoretical frameworks so as to yield robust evidence.

Conclusions: There is expressed commitment to coordinated care and to putting the patient in the centre. However to achieve this, new interactive patient portals will be needed to enable peer communication by all stakeholders including patients and professionals. Few portals capable of this exist to date. The evaluation of these portals as enablers of system change, rather than as simple windows into electronic records, is at an early stage and novel evaluation approaches are needed.
Assessment of Genetic Heterogeneity in Structured Plant Populations Using Multivariate Whole-Genome Regression Models
Authors: Lehermeier Christina , Schön Chris-Carolin , de los Campos Gustavo
Published: June 2015

Plant breeding populations exhibit varying levels of structure and admixture; these features are likely to induce heterogeneity of marker effects across subpopulations. Traditionally, structure has been dealt with as a potential confounder, and various methods exist to “correct” for population stratification. However, these methods induce a mean correction that does not account for heterogeneity of marker effects. The animal breeding literature offers a few recent studies that consider modeling genetic heterogeneity in multibreed data, using multivariate models. However, these methods have received little attention in plant breeding where population structure can have different forms. In this article we address the problem of analyzing data from heterogeneous plant breeding populations, using three approaches: (a) a model that ignores population structure [A-genome-based best linear unbiased prediction (A-GBLUP)], (b) a stratified (i.e., within-group) analysis (W-GBLUP), and (c) a multivariate approach that uses multigroup data and accounts for heterogeneity (MG-GBLUP). The performance of the three models was assessed on three different data sets: a diversity panel of rice (Oryza sativa), a maize (Zea mays L.) half-sib panel, and a wheat (Triticum aestivum L.) data set that originated from plant breeding programs. The estimated genomic correlations between subpopulations varied from null to moderate, depending on the genetic distance between subpopulations and traits. Our assessment of prediction accuracy features cases where ignoring population structure leads to a parsimonious more powerful model as well as others where the multivariate and stratified approaches have higher predictive power. In general, the multivariate approach appeared slightly more robust than either the A- or the W-GBLUP.

Published: June 2015

Telemedicine is a technological tool that is improving the health of children around the world. This report chronicles the use of telemedicine by pediatricians and pediatric medical and surgical specialists to deliver inpatient and outpatient care, educate physicians and patients, and conduct medical research. It also describes the importance of telemedicine in responding to emergencies and disasters and providing access to pediatric care to remote and underserved populations. Barriers to telemedicine expansion are explained, such as legal issues, inadequate payment for services, technology costs and sustainability, and the lack of technology infrastructure on a national scale. Although certain challenges have constrained more widespread implementation, telemedicine’s current use bears testimony to its effectiveness and potential. Telemedicine’s widespread adoption will be influenced by the implementation of key provisions of the Patient Protection and Affordable Care Act, technological advances, and growing patient demand for virtual visits.

Simultaneous determination of thimerosal and aluminum in vaccines and pharmaceuticals with the use of HPLC method
Authors: Zaręba M. , Sanecki P.T. , Rawski R.
Published: June 2015

A simple and convenient chromatographic method of simultaneous separation, identification, and quantitative determination of thimerosal (TM) (preservative) and aluminum (adjuvant) in vaccines and pharmaceuticals by reversed phase highperformance liquid chromatography (RP-HPLC) with visible (VIS) detection was developed and validated. Due to postcolumn derivatization with dithizone, any interference from matrix was excluded. Similarly, a possibility of on-column decomposition of dithizonates was eliminated. Evaluated detection limits were 0.3 μg TM and 3.0 μg Al, which correspond to the smallest, but possible to recognize, visible peak.
Water-based Engineering & Fabrication: Large-Scale Additive Manufacturing of Biomaterials
Authors: Mogas-Soldevila Laia , Oxman Neri
Published: June 2015

In nature, water assembles basic molecules into complex multi-functional structures with nano-to-macro property variation. Such processes generally consume low amounts of energy, produce little to no waste, and take advantage of ambient conditions. In contrast digital manufacturing platforms are generally characterized as uni-functional, wasteful, fuel-based and often toxic. In this paper we explore the role of water in biological construction and propose an enabling technology modeled after these findings. We present a water-based fabrication platform tailored for 3-D printing of water-based composites and regenerated biomaterials such as chitosan, cellulose or sodium alginate for the construction of highly sustainable products and building components. We demonstrate that water-based fabrication of biological materials can be used to tune mechanical, chemical and optical properties of aqueous material composites. The platform consists of a multi-nozzle extrusion system attached to a multi-axis robotic arm designed to additively fabricate extrusion-compatible gels with graded properties. Applications of the composites include small and medium-scale recyclable objects, as well as temporary largescale architectural structures.

Published: June 2015

A technology is presented for the production of soft and rigid circuits with an arbitrary 2.5D fixed shape. The base of this technology is our proprietary technology for elastic circuits with a random shape, in which the elastic thermoset (mostly PDMS) polymer is now replaced by soft or rigid thermoplastic variants. An additional thermoforming step is required to transform the circuit from its initial flat to its final fixed 2.5D shape, but for rigid fixed shape circuits only one-time stretchability of the extensible interconnects is required, relieving the reliability requirements.
FEATURES OF AUTONOMIC RESPONSE IN CHILDREN WITH BRONCHIAL ASTHMA IN THE PERIOD OF EXACERBATION
Authors: Lebedenko A. A. , Semernik O. E.
Published: June 2015

Background: Asthma is one of the urgent problems of modern pediatrics, but neuroregulation mechanisms underlying this disease have not been fully disclosed so far. The autonomic interactions assessment in patients with bronchial asthma is important to understand the pathogenesis and prognosis of the disease. Objective: The aim of the study was to investigate features of autonomic response in children with asthma in the period of exacerbation. Methods: The autonomic nervous system (ANS) of 82 children aged 6 to 18 years old with asthma in the period of exacerbation were investigated. The spectral analysis of the heart rate variability and the correlation rhythmography method (skaterography) were used to assess the ANS state. Investigations were carried out at rest and after clinoorthostatic test. Results: Non-respiratory (slow) waves reflecting the degree of activity of humoral and neural canals of heart rate central regulation were dominated at the spectrogram of 72 (87.80%) children experiencing asthma attack; more than half of patients (58.53%) had predominantly very low-frequency component (VLF%) in the range of fluctuation rate that indicated the influence of neurohumoral regulation. A significant increase in vagosympathetic balance coefficient (LF / HF) was recorded after clinoorthostatic test indicating the activation of the sympathetic nervous system. According to the correlation rhythmography data, a considerable scattering of scattergram points was detected in patients in the baseline state that indicated the predominant influence of parasympathetic nervous system. After the clinoorthostatic test, on the contrary, we observed the «tightness» of the scattergram cloud that could indicate sympathicotonia. Conclusion: The imbalance of the autonomic nervous system in the form of activation of the sympathetic and neurohumoral regulation department was found in children with asthma.
Electrical charges and energies of cement and pozzolan particle surfaces
Authors: Tasci Eda , Yılmaz Bulent
Published: June 2015

The aim of this study was to identify interaction mechanisms among particles in the hydration of pozzolan cements. To this end, chemical, physical, mineralogical and electrokinetic analyses of samples were conducted. Furthermore, free surface energy components were defined by Van Oss, Chaudry and Good equations and the contact angle values of samples were determined by using the thin layer wicking method. The results show that the addition of water turns solid–air interfaces into solid–liquid interfaces (wetting), while attraction and repulsion take place depending on the electrical charges on particle surfaces. While total surface energy and components of particles seek to attain balance as a result of wetting, hydration and pozzolanic reactions occur.
Educated Ignorance: What Faculty Don’t Know and Why Faculty Can’t Lead Intercollegiate Athletics Reform
Authors: Feezell Travis
Published: June 2015

Contemporary writings on the tension of athletics and academics in American higher education have often focused on the incompatibility of sporting endeavors and institutional missions. In particular, scholarship has stressed the ills of a financially directed collegiate sports machine at odds with the general educational aims of colleges and universities. However, this essay attempts to examine the historical and structural traditions of higher education, particularly those surrounding faculty, as a means of evaluating the tension. Moreover, the essay suggests a radical re-evaluation of those structures as a means to ameliorate the ongoing scandal in our institutions.
Mais cinco passos e irá transformar-se numa nova pessoa: o encerramento processual do campo experiencial em Every Day the Same Dream
Authors: Duret Christophe
Published: June 2015

Este artigo apresenta uma análise do jogo editorial Every Day the Same Dream (EDSD). O EDSD assume as características específicas de um romance de tese (um “jogo de tese”, neste caso específico), que Suleiman (1983: 1) definiu como sendo um tipo de romance que avança explicitamente “um corpo doutrinário ou sistema de ideias reconhecidos”, e que apresenta um “inequívoco sistema de valores dualista, [...] regras de ação orientadas para o leitor [e um] intertexto doutrinal” (Suleiman, 1983: 54). Segundo o princípio da retórica processual (Bogost, 2008), a tese do EDSD é defendida especialmente através de uma estrutura formal do jogo, sobretudo nos processos de resolução de problemas efetuados pelo jogador. Por conseguinte, analisamos o EDSD como um jogo de tese, propondo o conceito de “micro-instrumento de encerramento processual do campo experiencial” resultante do encontro entre as ciências hermenêuticas e cognitivas. O objetivo é descrever as estratégias utilizadas entre os jogadores para transmitir uma mensagem persuasiva e a analisar a sua receção.
GTFO!! - Posicionamento como estratégia de interação na comunicação MMORPG
Authors: Swoboda Birgit
Published: June 2015

OMG! Lol n00b :)! Quando os jogadores, sobretudo de MMORPG (Massively Multiplayer Online Role-Playing Games, i.e. jogos de interpretação online em massa para múltiplos jogadores) como o World of Warcraft®, falam entre si, adaptam a linguagem às suas necessidades, a exemplo do que fazem os falantes de uma língua. É errado presumir que expressões como smileys, acrónimos e neologismos constituem uma deterioração da linguagem atual. Antes pelo contrário, estas expressões podem ser vistas como exemplos de criatividade, eficiência e marcadores de grupo. Além disso, estas expressões ajudam os jogadores a posicionarem-se nas conversas, podendo por conseguinte ser vistas como estratégias de interação ativas no discurso dos jogos. Mas embora a comunicação seja de importância primordial para alcançar os objetivos e para efeitos de interpretação nos MMORPG, há vários desafios que se colocam aos jogadores, como situações de elevado stress, falta de pistas paralinguísticas e obstáculos interculturais. Recorrendo a um inquérito online, a um corpus compilado pela própria e a teorias de pragmática, este artigo estuda as estratégias de interação utilizadas pelos jogadores de MMORPG.
Game as text as game: the communicative experience of digital games
Authors: Mendonça Carlos Magno Camargos , Freitas Filipe Alves de
Published: June 2015

We propose to regard video game as text, but not by literally understanding it as a verbal expression, and instead recognizing that many assumptions of literary theory are relevant to its analysis. This option seems to put us in sync with the narratologists, who exalt games as new manifestations of narrative, but cling to a conception of text as world that values illusionist effects. Instead, we are interested in experiences that, against this perspective, recognize the possibility of regarding game as a text that is a game - an incomplete object that is to be updated by the reader in a self-reflective relationship with the signs that compose it, a central notion to theories such as Iser’s and Dewey’s. Then, instead of focusing on strategies of immersion on large virtual worlds, we favor small independent casual games (such as Small Worlds, Grey, The Beggar, and Dys4ia) analyzing how, in these, take place experiences that allow us to re-examine the aesthetic potential of the medium.
Narrative, history, and fiction: history games as boundary works
Authors: Telles Helyom Viana , Alves Lynn
Published: June 2015

This work arises from the reflections generated by a post-doctoral study that investigates how history games can contribute to the production and dissemination of representations, pictures, and imaginaries of the past. We understand history games to be digital electronic games whose structure contains narratives or simulations of historical elements (Neves, 2010). The term notion of “border works” is used by Glezer and Albieri (2009) to discuss the role of literary and artistic works that, standing outside the historiographical field and having a fictional character, are forms of the dissemination of historical knowledge and approximation with the past. We want to show how, under the impact of the linguistic turn, the boundaries between history and fiction have been blurred. Authors such as White (1995) and Veyne (2008) found both a convergence with and identification between historical narrative and literary narrative that interrogates the epistemological status of history as a science. These critiques result in an appreciation of fictional works as both knowledge and the dissemination of historical knowledge of the past. We then examine the elements of the audiovisual narratives of electronic games (Calleja, 2013; Frasca, 1999; Jull, 2001; Murray, 2003; Zagalo, 2009) in an attempt to understand their specificity. Next, we investigate the place of the narrative and historical simulations of electronic games in contemporary culture (Fogu, 2009). Finally, we discuss how historical knowledge is appropriated and represented by history games (Arruda, 2009; Kusiak, 2002) and analyze their impact on the production of a historical consciousness or an imaginary about the past.
Interactivity, expressiveness and engagement in newsgame “Back to 1964: your life under the dictatorship”
Authors: França Lilian Cristina Monteiro
Published: June 2015

In 2014, a series of events marked the 50th anniversary of the military coup in Brazil. The popular Superinteressante magazine launched a review of the facts through the newsgame “Back to 1964: your life under the dictatorship”. The purpose of this research paper is to analyze the newsgame, considering its expressiveness, engagement and experience proportionate to the player. The analysis draws heavily on concepts developed by Frasca (2001), Bogost (2008), Bogost, Ferrari & Schweizer (2010), Iurgel & Zagalo (2009), Ferrari (2009), Gonçalves & Zagalo (2010), Zagalo (2012), Sicart (2008), among others. The experiences with the game were used to categorize the levels of interactivity and reactivity, according to the possible paths followed by the reader/player. The extent to which the proposed simulation delineated narratives linked to the editorial profile of the magazine, and to what extent this can be used to encourage public debate.
Digital narratives: a study of the Arcade Fire interactive music videos
Authors: Barboza Elisa Maria Rodrigues
Published: June 2015

Initially seen as an audiovisual product made mainly for television, the music video, in recent years, has been expanding itself and gaining strength in the virtual environment. The possibility of easy and quick access through websites such as Vimeo and YouTube, besides the greater freedom these sites offer in comparison to the schedules of television channels, was only the beginning of the process of this format’s creative development. Its embracing of the technological changes culminates with the appearance of interactive music videos that strengthen investments made in experiences of digital narratives. In this context, one of the bands that stands out is Arcade Fire, whose trajectory already counts with four interactive audiovisual projects, namely Neon Bible (Vincent Morisset, 2007), Sprawl II (Vincent Morisset, 2010), The Wilderness Dowtown (Chris Milk, 2010) and Just a Reflektor (Vincent Morisset, 2013).
The academic condition and its enemies
Authors: Martins Moisés de Lemos
Published: June 2015

In the name of the certification of ‘quality’ and ‘excellence’, the University of Minho now seems condemned only to carry out procedures which, in education and research, certify routine and conformity, efficiency and utility, thus confirming the hegemony of instrumental reason. It is, however, my purpose in this study to reflect on academic freedom in the university. This issue demands that one should address one’s questions to the nature of the university itself, to the academic profession, as well as to its vocation and mission. What is the university today? What are the forces that traverse it? What blows has it sustained? What are the threats it is exposed to? What are its contradictions? What demands must it comply with? What should its response be?

Durante los años 2011 a 2013 se han localizado, identificado y excavado parcialmente los restos de un nuevo complejo termal en la ciudad hispanorromana de Baelo Claudia (Tarifa, Cádiz), situado en el suburbium occidental de la ciudad, junto a la línea de costa. Denominadas Termas Marítimas, construidas en la primera mitad del s. II d.C. y abandonadas en época de Diocleciano/Constantino han sido excavadas estratigráficamente con detalle, habiéndose detectado la existencia de fases anteriores (que se remontan al s. II a.C.) y una continuidad de uso del ambiente en época tardorromana y moderna, vinculada con la explotación de los recursos marinos. Especialmente singular ha sido la constatación del desplome traumático de parte de los paramentos de las habitaciones del edificio en dos momentos concretos: por un lado en la Antigüedad Tardía (500 d.C. circa), ya que una unidad muraria de una de las habitaciones (H-3), anexa a la natatio, se localizó completamente derrumbada sobre el suelo, conexionada; y por otro, el desplome del muro oeste de la natatio y el oriental de la cisterna, estructuras de más de seis metros de longitud y cuatro de altura mínima conservada, desplomadas sobre los niveles de abandono del asentamiento en época bajomedieval o moderna (ss. XIV-XV d.C.). Se trata en ambas ocasiones de colapsos estructurales no habituales en circunstancias normales en los procesos de sedimentación arqueológica, por lo que es muy probable que su desplome se pueda vincular con eventos sísmicos u otras causas naturales similares.
La ocupación del litoral onubense en época romana y su relación con eventos marinos de alta energía.

Published: June 2015

Las investigaciones geomorfológicas y arqueológicas que actualmente se están desarrollando en el Paraje Natural Marismas del Odiel - reserva de la Biosfera por la UNESCO-, especialmente en el cordón arenoso de La Cascajera, han ofrecido interesantes resultados que permiten retomar los estudios sobre la ocupación del litoral onubense en época romana desde un punto de vista diacrónico en el tránsito del bajo imperio hacia la tardoantigüedad. A este respecto son numerosas las factorías pesqueras (cetariae) que jalonan la costa más occidental de la antigua Provincia Baetica y en las cuales, ahora tras un proceso de revisión, se pueden intuir o comprobar momentos de ruptura y recuperación en sus explotaciones que habría que poner en relación con eventos marinos catastróficos (EWE) que, de manera histórica, han afectado a estas costas.
Logro de aprendizajes significativos a través de la competencia transversal “trabajo colaborativo” en educación superior

The development of competences in Higher Education today has given rise to several studies relating to the skills necessary to meet the requirements of student learning. The following research study was conducted in response to the question posed about how the integrative competence, “collaborative work”, is developed to achieve meaningful learning in Higher Education. Within the generic competences, also referred to as transferable skills, we find the integrative competence known as collaborative work, which aims to have students build their knowledge together, through joint efforts and respect for participants, without imposing their authority. This involves defending different points of view, trying to be critical and constructive in order to reach agreements that ultimately lead to the achievement of objectives. This paper seeks to identify students who demonstrate higher-level capacity development in collaborative work and those who do not. The study gives voice to their concerns and opinions about the development of this competence, as well as discussing the characteristics of those who find it easiest to work collaboratively and the needs to be covered in order to carry out these actions efficiently.
Cultura política y libros de texto de educación para la ciudadanía en España
Authors: García Erika González
Published: June 2015

We think that one of the key points for the acquisition and later dissemination of the theory of political culture is the provision of various material and organizational bases. In other words, we are referring to the principal agents of socialization, who are actors who reproduce and transmit values, attitudes or behaviors to citizens. The aim of this article is to understand the type of political culture portrayed in Education textbooks for citizenship and  human rights approved in Spain.
Civil Rights in the Field: Carey McWilliams as a Public-Interest Historian and Social Ecologist
Authors: Sachs Aaron
Published: June 2015

This article argues that Carey McWilliams's primary emphasis in Factories in the Field was not on the scale of California agriculture, but on the basic civil rights of farm workers, especially free speech, free assembly, and collective bargaining. Only these civil liberties, McWilliams felt, could help equalize social relations and also improve environmental conditions in California agriculture. Furthermore, by interpreting the 1930s agitation on California farms as having deep roots in the past rather than simply being spurred by white refugees from the Dust Bowl, McWilliams launched a radical critique now recognizable in the writings of both New Western Historians and social ecologists.
No Clear Link between G Loadings and Heritability: A Twin Study from Korea
Authors: Choi Yu Yong , Cho Sun Hee , Lee Kun Ho
Published: June 2015

A fundamental theoretical question in intelligence research is to what extent the g factor and heritability coefficients of the subtests of an IQ battery are correlated. Five studies from Western countries showed modest to strong positive correlations (range = 43-.77), and six studies from a Japanese meta-analysis showed zero to modest correlations (range = −0.01–0.59). The Western and Japanese studies were compared with a Korean sample of 24 monozygotic and 20 dizygotic young adult twin pairs administered the Korean Wechsler Adult Intelligence Scale-Revised (WAIS-R). A univariate twin model was applied to all subscale scores leading to estimates of heritability for all scales, g loadings were also computed using principal-axis factor analysis. Finally, the correlation between the heritabilities and the g loadings of these scales were computed. The correlations of r = −.15 were not in line with previous studies. It could be that Spearman's hypothesis is less strongly confirmed for Northeast Asians, but it is also possible that the study will be an outlier in a future meta-analysis. More primary research and a meta-analysis of all studies are needed.
Effects of Stroboscopic Visual Training on Visual Attention, Motion Perception, and Catching Performance
Authors: Wilkins Luke , Gray Rob
Published: June 2015

It has been shown recently that stroboscopic visual training can improve visual-perceptual abilities, such as central field motion sensitivity and anticipatory timing. Such training should also improve a sports skill that relies on these perceptual abilities, namely ball catching. Thirty athletes (12 women, 18 men; M age = 22.5 yr., SD = 4.7) were assigned to one of two types of stroboscopic training groups: a variable strobe rate (VSR) group for which the off-time of the glasses was systematically increased (as in previous research) and a constant strobe rate group (CSR) for which the glasses were always set at the shortest off-time. Training involved simple, tennis ball-catching drills (9 × 20 min.) occurring over a 6-wk. period. In pre- and post-training, the participants completed a one-handed ball-catching task and the Useful Field of View (UFOV) and the Motion in Depth Sensitivity (MIDS) tests. Since the CSR condition used in the present study has been shown to have no effect on catching performance, it was predicted that the VSR group would show significantly greater improvement pre–post-training. There were no significant differences between the CSR and VSR on any of the tests. However, changes in catching performance (total balls caught) pre–post-training were significantly correlated with changes in scores for the UFOV single-task and MIDS tests. That is, regardless of group, participants whose perceptual-cognitive performance improved in the post-test were significantly more likely to improve their catching performance. This suggests that the perceptual changes observed in previous stroboscopic training studies may be linked to changes in sports skill performance.
Evidence for Differences in Men's and Women's Volleyball Games Based on Skills Effectiveness in Four Consecutive Olympic Tournaments

Published: June 2015

This study compares the differences in effectiveness of the five volleyball skills (serve, reception, attack, block, and dig) between men and women in high-level tournament games played at the last four consecutive Olympics. Results showed that men's and women's volleyball games are completely differentiated by two outcome measures. The first one is the higher proportion of faulty serves performed by men which is essentially attributable to the 19 cm difference in net height, while the second one derives from the fact that men outperform women at the execution of the attack.
