Exogenous stress hormones alter energetic and nutrient costs of development and metamorphosis
Authors: Kirschman Lucas J. , McCue Marshall D. , Boyles Justin G. , Warne Robin W.
Published: July 2017

Variation in environmental conditions during larval life stages can shape development during critical windows and have lasting effects on the adult organism. Changes in larval developmental rates in response to environmental conditions, for example, can trade-off with growth to determine body size and condition at metamorphosis, which can affect adult survival and fecundity. However, it is unclear how use of energy and nutrients shape trade-offs across life stage transitions because no studies have quantified these costs of larval development and metamorphosis. We used an experimental approach to manipulate physiological stress in larval amphibians, along with respirometry and 13C-breath testing to quantify the energetic and nutritional costs of development and metamorphosis. Central to larval developmental responses to environmental conditions is the hypothalamus pituitary-adrenal/interrenal (HPA/I) axis, which regulates development, as well as energy homeostasis and stress responses across many taxa. Given these pleiotropic effects of HPA/I activity, manipulation of the HPA/I may provide insight into costs of metamorphosis. We measured the energetic and nutritional costs across the entire larval period and metamorphosis in a larval amphibian exposed to exogenous glucocorticoid (GC) hormones- the primary hormone secreted by the HPA/I axis. We measured metabolic rates and dry mass across larval ontogeny, and quantified lipid stores and nutrient oxidation via 13C-breath testing during metamorphosis, under control and GC-exposed conditions. Changes in dry mass match metamorphic states previously reported in the literature, but dynamics of metabolism were influenced by the transition from aquatic to terrestrial respiration. GC-treated larvae had lower dry mass, fat stores, and higher oxygen consumption during stages where controls were conserving energy. GC-treated larvae also oxidized greater amounts of 13C-labelled protein stores. These results provide evidence for a proximate cause of the physiological trade-off between larval growth and development, and provide insight into the energetic and nutrient costs that shape fitness trade-offs across life stages.
Women as editors-in-chief of environmental science journals
Authors: Yeverino-Gutiérrez Myrna L , González-González Ma del Rosario , Corral-Symes Ruth , González-Santiago Omar
Published: July 2017

This research note describes an analysis regarding the role of women as editors-in-chief of environmental science journals. The list of journals analyzed was obtained from the database of “Web of Science”, published in 2015. This database does not include information on the name or gender of the editors-in-chief of journals, so a web search was performed. The results show that gender inequality is present in this important field of science. Causes of this bias merit more and profound research. The bias observed may not apply to journals of others areas of science.
The mid-childhood and adolescent antecedents of women’s external locus of control orientation
Authors: Golding Jean , Gregory Steven , Iles-Caven Yasmin , Nowicki Stephen
Published: July 2017

Background: External locus of control orientation (ELOC) is a powerful predictor of adverse consequences in regard to health, educational attainment, inter-personal relationships and well-being. Although many cross-sectional studies have been carried out, relatively little is known about antecedent factors influencing the development of ELOC.

Methods: Over 12,000 pregnant women who enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC) in south-west England, had completed a brief version of the Adult Nowicki-Strickland Internal-External LOC scale, together with detailed questions concerning their own parents and childhood.  A series of hypothesis-free structured backwards stepwise logistic regression analyses used an exposome approach with ELOC as the outcome.

Results: Significant positive associations were found with smoking of the parents of the surveyed women, including prenatal exposure, and their own onset of regular smoking in mid-childhood (6-11 years). Increased odds of ELOC were also found with the absence of their fathers in early childhood, presence of older siblings, and with being born and brought up in the same area as they resided in at the time surveyed. Protective influences in the surveyed women included positive rating of their mother’s care, having a relatively educated mother, attending boarding school, their own age (the older they were, the less likely were they to have an external orientation), having a mentally ill parent, a sibling hospitalized or a relative die.

Conclusions: There are two conclusions: (i) that not all stressful events contribute to the development of ELOC and it would be essential for models of antecedents of ELOC to take note of this complexity, and (ii) there are consistent (albeit unexpected) findings that highlight associations with cigarette smoke exposure of the woman from fetal life through to when starting to smoke regularly herself in mid-childhood. It is important that these findings are tested in other populations.
Selling or Leasing? Pricing Information Goods with Depreciation of Consumer Valuation
Authors: Dou Yifan , Hu Yu Jeffrey , Wu D. J.
Published: July 2017

Should a monopolistic vendor adopt the selling model or the leasing model for information goods or services? We study this question in the context of consumer valuation depreciation. Using a two-period game-theoretic model, we consider two types of consumer valuation depreciation for information goods or services: vintage depreciation and individual depreciation. Vintage depreciation assumes that a good or service loses some of its appeal to consumers as it becomes dated, and this effect persists independent of usage. Individual depreciation instead assumes that valuation depreciation happens only for consumers who have consumed or experienced the good or service. We identify conditions under which each pricing model is preferred. For vintage depreciation information goods, the leasing model dominates the selling model in vendor profit. For individual depreciation information goods, the selling model dominates the leasing model as long as the magnitude of individual depreciation exceeds a certain threshold; otherwise, leasing dominates selling. We consider several model extensions such as when network effects are present. Furthermore, we show a negative interaction effect between vintage depreciation and network effects in vendor profit. By contrast, the interaction effect between individual depreciation and network effects can be either negative or positive, depending on the magnitude of individual depreciation. Managerial implications are also discussed.
To Be or Not to Be Linked: Online Social Networks and Job Search by Unemployed Workforce
Authors: Garg Rajiv , Telang Rahul
Published: July 2017

Prior research suggests that social connections, including acquaintances, friends, and family, are valuable in a job search process. In these studies, the size of an average job seeker’s network was much smaller and limited by the available modes of communication and the costs associated with maintaining social connections. However, the recent growth of online social networks has enabled job seekers to stay connected with many connections, weak or strong. Thus, the number of online connections—especially weak—has increased significantly. In this paper, we first examine whether an individual’s social network plays a role in driving job search behavior, taking into account online social networking sites (e.g., LinkedIn) and other job search modes. Second, we examine how ties in online social networks (both weak and strong) affect job search outcomes (modeled sequentially as job leads, interviews, and offers), and we compare the findings to job outcomes from traditional job search modes (e.g., career fairs, newspaper, Internet postings, and friends and family). To do so, we first construct an economic model of search behavior incorporating cost and benefit functions; we then estimate the model to recover structural parameters using the survey data of 424 users. Our findings show that users are spending more time searching for jobs on social networking sites. In addition, users’ strong ties play a significant role in job search and are especially helpful in generating job leads, interviews, and offers; the weak ties, on average, are ineffective in generating positive outcomes and marginally negative in some cases.

Competing by Restricting Choice: The Case of Matching Platforms
Authors: Halaburda Hanna , Jan Piskorski Mikołaj , Yıldırım Pınar
Published: July 2017

We show that a two-sided matching platform can successfully compete by limiting the number of choices it offers to its customers, while charging higher prices than platforms with unrestricted choice. We develop a stylized model of online dating where agents with different outside options match based on how much they like each other. Starting from these microfoundations, we derive the strength and direction of indirect network effects and show that increasing the number of potential matches has a positive effect due to larger choice, but also a negative effect due to competition between agents on the same side. Agents resolve the trade-off between these competing effects differently, depending on their outside options. For agents with high outside options, the choice effect is stronger than the competition effect, leading them to prefer an unrestricted-choice platform. The opposite is the case for agents with low outside options, who then have higher willingness to pay for a platform restricting choice, as it also restricts the choice set of their potential matches. Moreover, since only agents with low outside options self-select into the restricted choice platform, the competition effect is mitigated further. This allows multiple platforms offering different number of choices to coexist without the market tipping.

Stochastic Dynamic Inventory Problem Under Explicit Inbound Transportation Cost and Capacity
Authors: Zhang Liqing , Çetinkaya Sıla
Published: July 2017

We study a practical generalization of the classical stochastic dynamic inventory problem where privately owned trucks with limited cargo capacity are used to transport the replenishment quantity. The resulting replenishment cost function also includes the traditional fixed setup cost, and it is known as a multiple setup cost structure, which leads to complicated cost-to-go functions in the problem of interest. We introduce the concepts of non-(Δ, C)-decreasing and [Formula: see text], and we develop a sophisticated replenishment policy called the [Formula: see text] policy. We examine the sufficient conditions under which the new policy is optimal. Our results offer a detailed characterization of optimal policies and generalize the existing theory on the concepts of K-convexity and non-K-decreasing. In doing so, we are able to investigate a traditional stochastic inventory problem which has remained open in the literature for more than four decades.

Patient information needs before and after ileo-anal pouch surgery
Authors: Sammut Jacqueline , Xuereb Rita Borg , Scerri Josianne
Published: July 2017

Over the past 40 years, ileo-anal pouch surgery has become the operation of choice in the management of patients with ulcerative colitis requiring surgery. To identify the ongoing information needs of patients before and after this surgery, semi-structured interviews were conducted with nine people who have had an ileo-anal pouch formed as a consequence of ulcerative colitis. The transcribed interviews were analysed using interpretative phenomenological analysis. Three major themes were identified: ‘facing the unknown’, ‘forewarned is forearmed’ and ‘communicative support—the way forward’. The majority of participants expressed satisfaction with the information provided relating to the surgical procedure. However, less satisfaction was expressed with information relating to quality of life issues, such as sexual and dietary concerns after surgery. Health professionals need to provide individualised information that targets patients' unique needs and addresses their ongoing concerns that extend beyond the immediate post-surgical period.
Big Data, Platform Economy and Market Competition: A Preliminary Construction of Plan-Oriented Market Economy System in the Information Era
Authors: Binbin Wang  , Xiaoyan Li
Published: July 2017

Whether the planned economy, as one of the two main economic systems, can be reconstructed in the era of big data is an extremely important proposition in theory and reality. With the great debate on the feasibility of the planned economy in the 1930s, Lange model of centralized planning and market simulation came into being. After the information revolution in 1970s, the thought of planned economy characterized by market democracy and model of “democratic planned participatory socialism” rose in the west and the plan-oriented market economy system is expected to build in the era of big data. This kind of economy system should coordinate centralized planning and democratic planning, take big data as technical condition, platform economy as institutional and organizational conditions, to forming the big data–based and state-owned enterprises leading operated Internet platform economy in the field of competition, which can achieve to “make the market play a decisive role in the allocation of resources and the state play the leading role,” and achieve the comprehensive goals of reflecting consumer preferences, playing a role of law of value, highlighting the guidance of industrial planning, strengthening macro-control and reducing the cost of bureaucracy.
On the impossibility of archiving the radio and its virtues
Authors: Hagen Wolfgang
Published: July 2017

The article discusses the general history of the radio archive in Germany. Such archives were established since radio broadcasts were pre-produced. Firstly, this was the case in 1928 and led to the set-up of appropriate departments, deliberated to deliver the pre-recorded sound carriers right on time for the transmission. This is the beginning of the radio archive, which therefore at no time followed an archival idea. For this reason, even today, there are no radio archives that meet archival principles. In this respect, we propose to make the contents of the ­existing – so-called – radio archives available on the World Wide Web according to the model of UbuWeb that by now holds successful important artistic audio-visual documents for two decades.
Lossless compression and the future of memory
Authors: Jancovic Marek
Published: July 2017

Lossless video compression codecs such as FFV1 are currently emerging as a central organizing principle of archival practice. With reference to the perceived perfect reproducibility of digital objects, they promise to alleviate one of the great burdens of media preservation: decay. Recent large-scale international efforts to standardize lossless archival storage signalize a profound change in the relationship between loss, memory and history. This article examines the volatile status of lossless compression within cultural heritage institutions working towards format standardization. Engaging with a broader critique of contemporary archival policies, it questions the certainty with which lossless compression schemes frame decay as loss and contributes to the discussion surrounding the historicity and materiality of digitized objects and the historical value of decay for cultural heritage.
Searching for D-9.com in the archives: An archaeology of a film’s website
Authors: Walden Kim Louise
Published: July 2017

Film marketing materials such as trailers and posters are regarded as ephemeral, but as they have migrated online, they have become increasingly pervasive and intriguing forms, colonizing the spaces before, between and beyond the film itself. The distinctions between promotion and content have become blurred, and arguably, some marketing campaigns have become as entertaining as the films they promote, which raises questions about the cultural value of these ephemera. In setting out to investigate what film websites contribute to the narrative ecology of the film, the award-winning promotional website for Neill Blomkamp’s District 9 (2009) promised to be a good starting point. However, the research did not get off to an auspicious start because shortly after it began, the site disappeared. The article gives an account of a media archaeological excavation undertaken to search for D-9.com. A search led to encounters with a wide range of digital archives including the Internet Archive and its Wayback Machine, the Webby awards as well the ‘new’ generation of Web 2.0 archives such as blogs, YouTube and social media sites. In the light of this journey, the article will reflect on digital archives from what media theorist Wolfgang Ernst referred to as the ‘machine perspective’ and how the mechanisms of the digital archives condition the way we know things about the recent digital past. It will conclude by suggesting that these archival encounters in this project revealed as much about the nature of digital archives as online film marketing and promotion.
The materials of memory: Tracing archives in communication studies
Authors: Timcke Scott
Published: July 2017

This article contributes notes towards the development of a communicative approach to investigating archives. Such an approach is vital if one wishes to review features ranging from political or cultural reference points to the ecology of communication in the modern state. Through splicing together recent developments in the philosophy of mind with scientific publications on the bio-chemical cognitive process of memory, a case is presented where the archive is a useful bedrock concept when considering communication processes. A latent goal turns on the hope of sparking a renewed appreciation of archival systems and their place within the wider body of communication theory.
A model of non-player character believability
Authors: Warpefelt Henrik , Verhagen Harko
Published: July 2017

In this study we aim to describe in what ways the behaviour of non-player characters (NPCs) affects to what extent the player finds the game experience to be believable. To this end, we have conducted an online survey, where respondents were asked to classify and describe NPCs. Furthermore, we also examined recordings of NPCs in games. These data sources were analysed using a model for NPC social believability in order to describe the effects of NPC behaviour in relation to how different types of NPCs are perceived as being believable. Based on this we were able to construct a model of NPC believability, which describes the NPC’s level of complexity and ability to handle a mutable social context. As described by the model, NPCs are currently less capable of handling changing social contexts. They do, however, show promise, and given current emerging technologies it is feasible that new types of more socially capable NPCs will arise within the near future.
Digital games and moral packaging: The impacts of in-game decisions on public pedagogical deliberation
Authors: Malazita James W. , Jenkins Alexander
Published: July 2017

This article examines the impact of the use of moral game designs in mainstream games upon public discourse. Rather than interviewing players about their moral experiences after gameplay, this article reads moral engagement through the pedagogical lens of Freire: that moral engagement must be measured through pedagogical action in the public sphere. Through discourse analysis, this article examines the presence and quality of moral deliberation and pedagogical action in online message boards surrounding three morally charged games: Mass Effect 3, Modern Warfare 2 and Civilization V. In the cases examined, players rarely adopted the ‘moral point of view’ or engaged in public pedagogy, opting instead to frame moral scenarios as ‘play’. A notable exception occurs when the content of the moral scenarios has already been explicitly framed in the public sphere as a matter for public moral debate.

Figure and ground, image and sound: The digital medium in Brian Eno’s Thursday Afternoon
Authors: Leung Godfre
Published: July 2017

This article analyses the discrepancy between the medium-specificity of Brian Eno’s 1985 compact disc (CD) Thursday Afternoon and the intermediality of its precursor, Eno’s 1984 video artwork of the same name. I historicize these seemingly contrasting aesthetic strategies vis-à-vis medium alongside an epistemological shift in our conception of the musical recording during the rise of the CD in the early-to-mid-1980s. I argue the counter-intuitive point that the home video version of Thursday Afternoon represents the fullest realization of Eno’s medium-specific inquiry into the emergent CD technology.
Educando en privacidad en el uso de las redes sociales
Authors: Argente Estefanía , Vivancos Emilio , Alemany José , García-Fornes Ana
Published: July 2017

Muchos adolescentes utilizan ampliamente las redes sociales para incrementar su sociabilidad sin ser conscientes del valor de la información compartida y de los riesgos potenciales existentes relacionados con su privacidad y seguridad en la red. La utilización indebida o la divulgación sin permiso de la información privada de los usuarios puede tener consecuencias no deseadas en la vida de las personas. Por ello, la prevención y formación en la protección de los datos resulta fundamental para evitar riesgos en Internet. Diversos autores consideran que la formación en el buen uso de las redes sociales debería estar integrada en el currículo formativo de los adolescentes y centrarse no solo en la formación teórica, sino también en fomentar cambios en actitudes y comportamiento. Por este motivo, hemos desarrollado una aplicación de red social de acceso restringido, llamada Pesedia, que permite educar a niños y adolescentes sobre los riesgos de las redes sociales y además fomentar el cambio de actitud hacia un uso responsable y adecuado de la privacidad en las redes sociales. Utilizando esta red social, se ha realizado una experiencia con 134 niños de entre 12 y 14 años, en el marco de la Escola d’Estiu 2016 (Escuela de Verano) de la Universitat Politècnica de València. Mediante un conjunto de juegos propuestos, los niños y adolescentes interactúan en Pesedia y aprenden a detectar acciones de riesgo que, de llevarse a cabo en una red social pública, podrían comprometer su privacidad. Con dichos juegos se les conciencia, entre otros aspectos, sobre los peligros de la exposición pública de los datos, del etiquetado y geoposicionamiento de las fotos, la descontextualización de las conversaciones, así como las repercusiones futuras de nuestra huella digital. En este artículo presentamos las características de esta red social, los talleres desarrollados y los principales resultados de esta experiencia.
Todo lo que nunca pensaste que los alumnos sub 18 sabían sobre proyectos

Published: July 2017

Organizar excursiones o meriendas, montar un equipo del juego on-line de moda, estudiar en grupo y muchas cosas más son actividades habituales en jóvenes (y no tan jóvenes). Las actividades anteriores pueden enmarcarse en la definición de proyecto, ya que todas cuentan con un marco temporal definido, tienen recursos limitados que es necesario gestionar y plantean objetivos que se desea cumplir. Sin embargo, basándonos en nuestra experiencia docente en asignaturas universitarias relacionadas con la gestión y dirección de proyectos informáticos, la enseñanza de esta materia es difícil. Al ser asignaturas de últimos cursos universitarios los alumnos llegan con malos hábitos adquiridos. El objetivo de este trabajo es doble: 1) Exponer cómo en actividades cotidianas aplicamos conocimientos de gestión de proyectos, aunque muchas veces no somos conscientes de ello. Queremos mostrar a nuestros futuros estudiantes el uso de buenas prácticas de gestión de proyectos tomando como referencia la Guía de los Fundamentos para la Dirección de Proyectos (Guía del PMBOK®) del Project Management Institute (PMI) y aplicándolo a la organización de una barbacoa. Así, el alumnado aprenderá que detrás de cada una de las preguntas que se plantean: ¿dónde lo haremos?, ¿cuántos seremos?, ¿qué llevaremos?, ¿cuándo? y otras tantas preguntas, se esconden buenas prácticas de gestión de proyectos; y 2) Plantear al profesorado, tanto universitario como no universitario, la importancia de ir incorporando en etapas tempranas de la formación de nuestro alumnado conceptos básicos sobre diferentes disciplinas aplicadas de forma amena y motivadora. Nuestros jóvenes saben más de gestión de proyectos de lo que ellos mismos creen y ayudarles a sacar este conocimiento a la luz les ayudará a gestionar un proyecto de forma natural cuando lleguen a la universidad. Para ello expondremos técnicas y herramientas sencillas para que su barbacoa sea un éxito.
El diseño instruccional inverso para un recurso educativo abierto en la Formación Profesional española: El caso de Web Apps Project
Authors: García Marcos Cristian Jorge , Cabero Almenara Julio
Published: July 2017

En este artículo se describe el proceso de diseño instruccional empleado para la elaboración de un medio educativo que desarrolla el currículo del módulo Aplicaciones Web correspondiente al Ciclo Formativo de Grado Medio de Sistemas Microinformáticos y Redes, que pertenece a la familia profesional de Informática y Comunicaciones dentro de los estudios de Formación Profesional. El modelo seguido para la creación del medio educativo es el diseño instruccional hacia atrás, en el que se comienza por los resultados de aprendizaje y se finaliza por los contenidos, de manera inversa al procedimiento utilizado en otros diseños instruccionales. El medio educativo se ha diseñado sustentado en el principio pedagógico del constructivismo y se ha recurrido a la creación de proyectos para que el estudiante se implique activamente en la elaboración de su conocimiento. El resultado es un recurso educativo abierto compuesto por seis secuencias didácticas, donde se persigue que el estudiante alcance habilidades de pensamiento de orden superior. Además de la apertura en el acceso, el uso, la adaptación y la redistribución del material, el presente artículo ofrece una visión detallada del proceso que se ha seguido en cada fase del diseño instruccional. De esta manera, el recurso educativo evoluciona de ser abierto en su contenido, a serlo además en su diseño, para que también este último sea accesible, reutilizable, adaptado y redistribuido por otros. El recurso educativo en abierto completo puede consultarse en el siguiente enlace: http://www.cristiangarcia.org/WebAppsProject/index.html
VirPLC: una metodología para el desarrollo de capacidades, habilidades y autoestima mediante la estimulación de la lógica con una herramienta sencilla, funcional y dinámica
Authors: Ferrer Rojas Antoni
Published: July 2017

La proliferación de entornos de programación como Logo, Minecraft, Code o Scratch es consecuencia de la efectividad de un lenguaje gráfico para la introducción del alumnado en la programación, pero algunos de los sistemas más novedosos, como App Inventor, resultan lentos en la interacción fundamental: “haz” / “prueba”. Propongo una alternativa enfocada a alumnado a partir de los 15 años. Se llama VirPLC y se orienta a algo tan funcional como el control de sistemas mediante dos pantallas: una de software, para programar, y una de hardware animado, para simular. VirPLC no pretende convertir al usuario en experto en automatización, sino facilitar un primer contacto entre el alumno y la lógica, mediante propuestas de problemas en sistemas de control prácticos, cercanos y reales como: mando de grúa, concurso de TV, alarma, puerta de supermercado, puerta de garaje, semáforo, ascensor... El/la alumno/a plantea tanto la operatividad lógica, como los requisitos de hardware (entradas y salidas). El software se trabaja de forma evolutiva y reiterada “haz” / “prueba” y consolídalo para mejorarlo. Además, permite la depuración de cada proyecto o “reto” en distintos niveles de perfeccionamiento, solidez, funcionalidad, seguridad y versatilidad. VirPLC es una alternativa que motiva al alumnado inquieto y luchador, para aplicar, tras unas nociones de Álgebra de Boole y antes de a la programación escrita, con objetos, eventos y clases. VirPLC es freeware, trabaja bajo Windows (desde XP hasta W10) y se puede descargar desde la WEB del autor. Al instalarlo, añade una carpeta con más de 30 ejemplos a menudo deliberadamente incompletos, junto con un minicurso con propuestas prácticas y variadas.
KOMPLEMENTER DAN REDUKSI KOMPETISI DALAM KETERKAITAN FUNGSIONAL DUA PUSAT RUANG PERKOTAAN DI KOTA JAYAPURA
Authors: Baharuddin Alfini , Wibisono Bambang Hari
Published: July 2017

Jayapura City is the capital of Papua Province, located at the eastern end of Indonesia and has a direct borders with neighboring countries, Papua New Guinea (PNG). The geographical conditions of Jayapura City are very diverse leads to the formation of separate urban centers. Currently there are two parts of urban centers in Jayapura City, known as Jayapura and Abepura. This situation gave rise to a unique character in the overall system of Jayapura City, so it is necessary to examine how the two urban centers interact in Jayapura City. This study aims to assess the functional linkages that occur between Jayapura and Abepura using the case study method. Data collected through direct observation, secondary data collection and structured interviews using a questionnaire. The results showed that the functional linkages that occurred between Jayapura and Abepura are complementary functions of their natural advantages, and functions that are homogeneous but did not compete in the provision of economic and public service. In this case, the functions homogeneous appearing not cause competition, resulting in a reduction of competition.
MENDEFINISIKAN KOTA INKLUSIF: ASAL-USUL, TEORI DAN INDIKATOR
Authors: Maftuhin Arif
Published: July 2017

Tulisan ini menjawab pertanyaan tentang apa yang disebut kota inklusif dan indikatornya. Secara akademik, nyaris tidak ada studi tentang ‘kota inklusif’. Padahal, dalam praktik, sudah banyak daerah yang berusaha menjadi, atau mengklaim diri, sebagai “kota inklusif”. Studi dalam artikel ini bersifat literer karena bertujuan menemukan gagasan dan landasan teoretis yang dapat digunakan untuk mendefinisikan “kota inklusif.” Karena definisi saja belum cukup, tulisan juga akan mengkaji indikator kota inklusif. Berdasarkan kajian teoretis yang dilakukan, penulis berpendapat ada empat indikator kota inklusif: (i) adanya partisipasi difabel; (ii) adanya upaya pemenuhan hak-hak difabel; (iii) terjaminya aksesibilitas; dan (iv) adanya sikap inklusif warga kotanya.Despite its recent popular use in Indonesia, “inclusive city” as an academic subject has been relatively neglected. The subject is interestingly absent from Indonesian academic journals in relevant studies. While the term has been globally used and discussed, it is used in a significantly different way. The objective of this paper is to propose a concept of “inclusive city” by defining its dimensions and indicators. It is a localized concept to promote a city that promotes, protects, and accommodates the rights of the disabled. To achieve that objective, this literary research seeks to find theoretical base to argue for inclusion of the disabled. Furthermore, it argues for four dimensions of an inclusive city: (i) a full participation of the disabled; (ii) a promotion of the rights of the disabled; (iii) accessibility; and (iv) inclusive attitude of the people. An elaboration of the indicators is provided afterward.

First, via the Mountain Pass theorem, existence of nonnegative solutions
is obtained when f satisfies superlinear growth conditions and λ
is large enough. Then, via the Ekeland variational principle, existence of
nonnegative solutions is investigated when f is sublinear at infinity and λ is small enough. More intriguingly, the paper covers a novel feature of Kirchhoff problems, which is the fact that the parameter a can be zero. Hence the results of the paper are new even for the standard stationary Kirchhoff problems.

Published: July 2017

Optical systems can benefit strongly from freeform surfaces; however, the choice of the right surface representation is not trivial and many aspects must be considered. In this work, we discuss the general approach classical globally defined representations, as well as the basic mathematics and properties of the most commonly used descriptions and present a new description developed by us for describing freeform surfaces.
Improving the thermoelectric power factor of PEDOT:PSS films by a simple two-step post-treatment method

Published: July 2017

This study demonstrates a simple two-step post-treatment method for improving the thermoelectric power factor of low-cost poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) films. The dry re-dispersible PEDOT:PSS pellets are cost-effective, however, they exhibit extremely low thermoelectric performance. On treating with ethylene glycol followed by hydrazine, the power factor of the PEDOT:PSS films increased from 0.0632±0.0097 μW m−1K−2 to 13.3±1.5 μW m−1K−2. The enhancement might be attributed to the effective removal of the free, non-complexed PSS chains and fine control of the oxidation level of PEDOT by the two-step post-treatment.

CytoMCS: A Multiple Maximum Common Subgraph Detection Tool for Cytoscape
Authors: Larsen Simon J. , Baumbach Jan
Published: July 2017

Comparative analysis of biological networks is a major problem in computational integrative systems biology. By computing the maximum common edge subgraph between a set of networks, one is able to detect conserved substructures between them and quantify their topological similarity. To aid such analyses we have developed CytoMCS, a Cytoscape app for computing inexact solutions to the maximum common edge subgraph problem for two or more graphs. Our algorithm uses an iterative local search heuristic for computing conserved subgraphs, optimizing a squared edge conservation score that is able to detect not only fully conserved edges but also partially conserved edges. It can be applied to any set of directed or undirected, simple graphs loaded as networks into Cytoscape, e.g. protein-protein interaction networks or gene regulatory networks. CytoMCS is available as a Cytoscape app at http://apps.cytoscape.org/apps/cytomcs.
A Generalized Approach for Measuring Relationships Among Genes
Authors: Wang Lijun , Ahsan Md. Asif , Chen Ming
Published: July 2017

Several methods for identifying relationships among pairs of genes have been developed. In this article, we present a generalized approach for measuring relationships between any pairs of genes, which is based on statistical prediction. We derive two particular versions of the generalized approach, least squares estimation (LSE) and nearest neighbors prediction (NNP). According to mathematical proof, LSE is equivalent to the methods based on correlation; and NNP is approximate to one popular method called the maximal information coefficient (MIC) according to the performances in simulations and real dataset. Moreover, the approach based on statistical prediction can be extended from two-genes relationships to multi-genes relationships. This application would help to identify relationships among multi-genes.
An Image Authentication Algorithm Using Combined Approach of Watermarking and Vector Quantization
Authors: Tiwari Archana , Sharma Manisha
Published: July 2017

This paper presents a two-stage watermarking technique for image authentication adapting the advantages of vector quantization (VQ). In the proposed algorithm, robust watermark and semifragile watermark are embedded independently in two successive stages. Robust watermark and VQ enhance the security of the system by providing double protection to the designed system, while semifragile watermark helps in authenticating the received image. Watermarks of varying sizes are embedded in the cover image, and their performance is measured in terms of peak signal-to-noise ratio (PSNR), weighted PSNR, and bit error rate. A threshold-based approach is suggested for identification of attacks as acceptable or malicious. The experimental results demonstrate the capabilities of the method in classifying attacks and correctly locating the tampered area. It is possible to detect and determine tampering with very high sensitivity. The present scheme outperforms previous algorithms in terms of imperceptibility, attack classification criteria, robustness feature, and tamper detection feature.
Interval-Valued Intuitionistic Fuzzy Confidence Intervals
Authors: Kahraman Cengiz , Oztaysi Basar , Cevik Onar Sezi
Published: July 2017

Confidence intervals are useful tools for statistical decision-making purposes. In case of incomplete and vague data, fuzzy confidence intervals can be used for decision making under uncertainty. In this paper, we develop interval-valued intuitionistic fuzzy (IVIF) confidence intervals for population mean, population proportion, differences in means of two populations, and differences in proportions of two populations. The developed IVIF intervals can be used in cases of both finite and infinite population sizes. The developed fuzzy confidence intervals are equivalent decision-making tools to fuzzy hypothesis tests. We apply the proposed confidence intervals to the differences in the mean lives and failure proportions of two types of radiators used in automobiles, and a sensitivity analysis is given to check the robustness of the decisions.
Nonlinear transient and thermal analysis of functionally graded shells using a seven-parameter shell finite element
Authors: Gutierrez Rivera Miguel , Reddy J. N.
Published: July 2017

In this paper the thermo-mechanical response of functionally graded plates and shells is studied using a continuum shell finite element model with high-order spectral/hp basis functions. The shell element is based on the seven-parameter first-order shear deformation theory, and it does not utilize reduced integration or stabilization ideas and yet exhibits no locking. The static and dynamic response of functionally graded shells, with power-law variation of the constituents, under mechanical and thermal loads is investigated by varying the volume fraction of the constituents. Numerical results for deflections and stresses are presented and compared with available analytical and finite element results from the literature. The performance of the shell element for transient thermal problems is found to be excellent.

Mechanical and electrical properties of polylactic acid/carbon nanotube composites by rolling process
Authors: Wang Lijun , Qiu Jianhui , Sakai Eiichi
Published: July 2017

In this work, the rolling process was employed to fabricate polylactic acid/multi-walled carbon nanotube (PLA/MWCNT) composites at room temperature. The effects of the rolling conditions on the mechanical and electrical properties of the fabricated composites were investigated. The evolution processes of the internal molecular structures, i.e. changes in molecular orientation and crystallinity, were examined by X-ray diffraction, differential scanning calorimetry, and density method. The results suggested that the molecular orientation improved; however, the crystallinity decreased when the rolling ratio increased. The analysis of the mechanical properties revealed that the rolled composites displayed anisotropy during the rolling process. In the rolling direction, after adding 1 wt.% MWCNTs, the tensile strength increased from 58.6 to 94.3 MPa with the rolling ratio, whereas the fracture strain sharply increased to 131.5% at the rolling ratio of 60%. In addition to the mechanical properties, electrical resistivity was also investigated; notably, this property was not significantly affected by the rolling process. Furthermore, the MWCNT dispersion and morphology were investigated by scanning electron microscopy. These findings offer a simple and effective method to fabricate conductive composites with excellent mechanical properties.

Sarmento, H, Figueiredo, A, Lago-Peñas, C, Milanovic, Z, Barbosa, A, Tadeu, P, and Bradley, PS. Influence of tactical and situational variables on offensive sequences during elite football matches. J Strength Cond Res 32(8): 2331–2339, 2018—This study examined the influence of tactical and situational variables on offensive sequences during elite football matches. A sample of 68 games and 1,694 offensive sequences from the Spanish La Liga, Italian Serie A, German Bundesliga, English Premier League, and Champions League were analyzed using χ2 and logistic regression analyses. Results revealed that counterattacks (odds ratio [OR] = 1.44; 95% confidence interval [CI]: 1.13–1.83; p < 0.01) and fast attacks (OR = 1.43; 95% CI: 1.11–1.85; p < 0.01) increased the success of an offensive sequence by 40% compared with positional attacks. The chance of an offensive sequence ending effectively in games from the Spanish, Italian, and English Leagues were higher than that in the Champions League. Offensive sequences that started in the preoffensive or offensive zones were more successful than those started in the defensive zones. An increase of 1 second in the offensive sequence duration and an extra pass resulted in a decrease of 2% (OR = 0.98; 95% CI: 0.98–0.99; p < 0.001) and 7% (OR = 0.93; 95% CI: 0.91–0.96; p < 0.001), respectively, in the probability of its success. These findings could assist coaches in designing specific training situations that improve the effectiveness of the offensive process.
Frequency- and Time-Domain Dependency of Electrical Properties of Cement-Based Materials during Early Hydration
Authors: Taha H. M. , McCarter W. J. , Suryanto B. , Starrs G.
Published: July 2017

The electrical properties of Portland cement, and cements containing supplementary cementitious materials (SCM), were obtained over the frequency range 1 kHz–10 MHz during the initial 24 h after gauging with water. The response was measured in terms of conductivity and permittivity with both parameters exhibiting significant temporal changes during this period. It was also evident that while the conductivity increased only marginally with increasing frequency of applied electrical field, the permittivity decreased by several orders of magnitude over this frequency range. Moreover, certain features of the permittivity response, which are related to bulk polarization processes, only revealed themselves in the higher frequency range (100 kHz–1 MHz), and went undetected at lower frequencies. The detailed frequency- and time- domain measurements allowed identification of several stages in the early hydration of cement-based materials and the response can be interpreted in terms of hydration kinetics, physico-chemical processes and microstructural development. It is shown that the methodology can be equally applied to cement pastes and concretes.
Stiffening Behaviors of Cement Pastes Measured by a Vibrational Viscometer
Authors: Chen Chun-Tao , Lin Chang-Wei
Published: July 2017

This study explores the stiffening behavior of cement pastes up to 30 min using a new vibrating-fork technique, in which the vibro-viscometer controls the electrical current to maintain a uniform vibrating amplitude of the sensor plate for approximately 0.2 mm at 30 Hz. The applied electrical current is related to the product of the apparent viscosity and the density. The viscosity evolutions of the cement pastes at water–cement ratios of 0.4, 0.5, and 0.6 in the presence or absence of high-range water-reducer admixtures (HRWRA) were compared using a rotational viscometer and a tuning-fork vibration viscometer. The results indicated that the viscosities increased with hydration time and decreased with admixture dosages. The vibration viscometer seems to have applied higher shear rates than the rotational viscometer during the early hydration so the viscosities measured by the vibration viscometer were always lower. However, the increases in the viscosity of the cement pastes, as measured by the vibration viscometer, were more stable than those measured by the rotational viscometer. In addition, the subtle increases in the paste viscosities during very early hydration were detected well by the vibration viscometer. The vibrating-fork technique has been proven to be a useful tool for characterizing microstructure changes in early cement pastes.
