Engineering Cost Information Management in Big Data Era

With the development of Chinese society, the era of big data and the increasing informatization, information and scientific systems have gradually formed in various fields and enterprises, but the process of improving company management has also received great challenges. Especially in the engineering cost industry, to comply with the requirements of the times, it is necessary to change the previous management method, but the era of big data has also brought new opportunities and opportunities to engineering cost management. The goals of the engineering cost industry, how companies can fully use the advantages of big data in engineering costs, solve related problems, and improve the overall social and economic benefits by means of data and information technology have become in-depth discussion questions. The purpose of this article is to study the problem of information management of engineering cost in the era of big data. By establishing a unified cost data collection standard on the basis of big data, the quality of data collection is improved, which facilitates the classification and processing of subsequent data, increases the source of data collection, and improves the quality of data. Improve the competitiveness of project cost management. Strengthen data mining and analysis, lower the threshold of data management, so that more project cost management staff can master. Based on the analysis of the needs of the platform, the frontline project cost personnel of the construction unit and the engineering cost consulting unit were the main survey objects, and it was found that most people have not worked for five years. And 62% of the engineering cost workers still get the latest project cost information from the project cost information journals and websites responsible for the cost station.

Christian-Muslim Coexistence in Peshawar City

Several scholarly works and media reports claim that the Christian minority in Pakistan is mistreated, persecuted, and discriminated against, giving an overall impression as if Christians are alienated from the main social stream everywhere in Pakistan and that the public at large is responsible for their miseries. Noticing that most of the above-mentioned works are theoretical or based on journalistic information, an attempt has been made through this empirical case study of Peshawar city to know the situation of Christian-Muslim coexistence on the ground. For this purpose, a mix method approach was used combining quantitative survey, qualitative interviews, and group discussions. Contrary to the prevailing negative impression, this study reveals that to a large measure Christian and Muslim communities are living together peacefully, at least in Peshawar city. Quantitatively, 68% of respondents, both Christians and Muslims, viewed their mutual social and neighborhood interaction as positive. The results of qualitative interviews also supported these findings. It is, therefore, concluded that apart from some Christian concerns which need to be addressed, overall Christian-Muslim coexistence at the societal level might not be marred by religious differences everywhere in Pakistan. Negative generalizations in this regard need to be revisited, to say the least.

Ciberfeminismo: emergencia y características del feminismo online en Corea del Sur


 
 
 
 Este trabajo estudia los grupos feministas online de Corea del Sur, definidos bajo el concepto marco de ciberfeminismo, con el objetivo de contextualizar su emergencia, analizar sus características y evaluar sus acciones a nivel cultural y político. La recolección de datos se realizó mediante el mapeo y selección de sitios web, información periodística y literatura especializada, y se procesaron los resultados en función de cinco dimensiones de análisis: características de los miembros de grupos ciberfeministas, tipos de colaboración, temas de interés, modalidades de la acción y posicionamiento con respecto a la comunidad LGBT. Se constató que el feminismo online en Corea se compone casi exclusivamente de mujeres estudiantes y profesionales; que los tipos de colaboración entre sus miembros asumen espacios online y offline; que estos grupos abordan temas “sensibles” y comparten información de difícil acceso; que la modalidad de acción puede dividirse entre activa y pasiva, aunque prevalece la primera; y que su posicionamiento con respecto a la comunidad LGBT se separa entre apoyo e inclusión de sus demandas en la lucha feminista y rechazo por considerar que sololas mujeres son sujeto de su debate. Se concluye evaluando la importancia social e influencia de la modalidad de feminismo en línea.
 
 
 

Nuevas narrativas periodísticas entre la información y la simulación lúdica: los docuwebs y los newsgames

Este artículo tiene por objetivo analizar cómo cooperan el periodismo digital y la cultura del videojuego moderno en dos formas de simulación lúdica e inmersión periodística: los docuwebs y los newsgames. Para ello, se ha establecido una metodología de análisis cualitativo con una doble perspectiva: el nivel del discurso informativo-periodístico (es decir, los contenidos y sus formas de proyección) y a nivel de retórica procedural (esto es, a través de las mecánicas de juego) que se aplica a dos casos de estudio de RTVE Lab: el newsgame MonteLab y el docuweb Guerra a la mentira. Los principales resultados muestran cómo el diseño de MonteLab establece un diálogo entre un rico sistema de fuentes periodísticas y unas mecánicas de juego que habilitan la toma de decisiones ante los problemas sociales de la actualidad. En una línea similar, el docuweb Guerra a la mentira establece un conjunto de casos reales y usa la verificación de la información y las fake news como motor periodístico sobre el que construir una propuesta lúdica de resolución de puzles e impulso narrativo. Por todo ello, y a modo de conclusiones, podemos comprobar que el newsgame contemporáneo busca empoderar al jugador como un ciudadano informado que explota las dinámicas lúdicas para proveer soluciones sociales basadas en informaciones periodísticas. Por otro lado, el docuweb supera el estaticismo hipertextual para adentrarse en dinámicas más complejas y diseños lúdicos más inmersivos gracias a la superación de la mera descripción periodística de la realidad.

Viewpoint: at the intersections of information, computing and internet research

PurposeThe purpose of this paper is to introduce a new collaboration between the Association of Internet Researchers (AoIR) and the Journal of Information, Communication and Ethics in Society (JICES).Design/methodology/approachThe paper uses historical, comparative and ethics-based approaches.FindingsThe collaboration is catalyzed by central interests shared between AoIR and JICES, namely, in the ethical and social impacts of the internet. The collaboration accordingly aims to bring research and reflection developed for the AoIR conferences to the JICES’ readership.Originality/valueThe value of this collaboration is considerable, as it promises extensive new cross-fertilization between the two communities. The viewpoint begins with a brief overview of the collaboration’s initiation by Prof Simon Rogerson and its logistics over the next two years. Following a general review of Information and Computing Ethics and Intercultural Information Ethics, an overview of ethical considerations fostered by AoIR is offered, focusing on the development of internet research ethics (IRE), especially its most recent expression in an IRE 3.0.

The publication of press releases as journalistic information. Comparative study of two Spanish newspapers

La distinción de lo que constituye un "evento noticiable" puede dar lugar a muchas interpretaciones. En este mundo de accesibilidad telemática, que es una consecuencia de la globalización, los eventos y los sucesos de todo tipo se pueden clasificar como noticias simplemente vistiéndolos como noticias. De acuerdo con los manuales de estilo y comunicación, la noticia tiene características propias: relevancia, interés social y proximidad, entre otras. Los comunicados de prensa se han perfeccionado como resultado de las agencias de relaciones públicas cada vez más sofisticadas, y con ellas la línea delgada entre la información y la publicidad ahora está borrosa. En este artículo, comparamos comunicados de prensa emitidos por empresas públicas y privadas con breves publicados en las secciones de economía de los periódicos. Como se verá, muchos de ellos coinciden y tienen algunas similitudes. La muestra utiliza breves publicados durante el primer semestre de 2014 en El Mundo y La Vanguardia, los periódicos en español de pago por lectura que ocupan un lugar destacado en el análisis del Estudio General de Medios. La metodología hace uso del programa Maple con su comando DetectPlagiarism para realizar una comparación ad hoc de los textos. El umbral de copia predeterminado para DetectPlagiarism es 0.35. Los índices de similitud entre los breves y los comunicados de prensa de La Vanguardia y El Mundo indican valores superiores a este umbral.

A SCIENTOMETRIC ANALYSIS OF THE EMERGING TOPICS IN GENERAL COMPUTER SCIENCE

Citations have been an acceptable journal performance metric used by many indexing databases for inclusion and discontinuation of journals in their list. Therefore, editorial teams must maintain their journal performance by increasing article citations for continuous content indexing in the databases. With this aim in hand, this study intended to assist the editorial team of the Journal of Information and Communication Technology (JICT) in increasing the performance and impact of the journal. Currently, the journal has suffered from low citation count, which may jeopardise its sustainability. Past studies in library science suggested a positive correlation between keywords and citations. Therefore, keyword and topic analyses could be a solution to address the issue of journal citation. This article described a scientometric analysis of emerging topics in general computer science, the Scopus subject area for which JICT is indexed. This study extracted bibliometric data of the top 10% journals in the subject area to create a dataset of 5,546 articles. The results of the study suggested ten emerging topics in computer science that can be considered by the journal editorial team in selecting articles and a list of highly used keywords in articles published in 2019 and 2020 (as of 15 April 2020). The outcome of this study might be considered by the JICT editorial team and other journals in general computer science that suffer from a similar issue.

DYNAMICS OF METAPHORICAL VERBALIZATION IMAGE OF KANZLERIN ANGELA MERKEL

The paper presents the results of modeling the multilayer structure of the image of Kanzlerin Angela Merkel , the core of which is the metaphorical layer of the political concept. The relevance of the study is due to the growing role of political communication in society and the lack of study of its image aspect. policy in terms of the objectives of the communication of power, the relationship of language and culture, emotion and cognition, the reflection in the language of the value picture of the world of the speakers of the German language. The article is carried out in the framework of cultural anthropology, linguocognitology, political linguistics and discoursology. As methodological basis of the study the following methods and approaches are used: the method of continuous sampling, the classification method, the method of cognitive modeling, the cognitive-interpretative method, the conceptual analysis, the method of statistical data processing. The analysis is based on the articles from the German information and political journals Der Spiegel and Focus for the period of 2005-2017. In the study, based on 8180 text fragments, metaphorical models and their subtypes are described, cognitive features and dominants of each period of the Chancellery A. Merkel are revealed.

Pesca marítima y acumulación por desposesión en Argentina (1966-2018): extranjerización del recurso, crisis socio-ambiental, precarización laboral y redistribuciones estatales

Para el marxismo clásico, la llamada acumulación originaria o primitiva se limitó a moldear la prehistoria del sistema capitalista. Sin embargo, y dado que ese proceso continuó operando sin interrupción, el geógrafo inglés David Harvey propone redefinirlo en términos de “acumulación por desposesión”. Sobre la base de bibliografía especializada, fuentes oficiales, investigaciones independientes e información periodística, este artículo busca tender puentes entre lo teórico y lo empírico estudiando la compleja relación entre acumulación por desposesión y pesca marítima en Argentina durante el período 1966-2018. Para ello, se recurre a cuatro categorías de análisis propuestas por dicho autor: cercamiento, privatización y apropiación neocolonial imperial de recursos naturales; despojo ecológico y producción de crisis; precarización laboral y trabajo esclavo; y redistribuciones estatales. Los resultados muestran claramente que, al menos en el caso argentino, la pesca marítima debe ser considerada e interpretada como una modalidad de acumulación por derecho propio.

العوامل المؤثرة في الأداء المهني لمحرري نشرات الأخبار في الفضائيات العراقية-بحث مستل من رسالة ماجستير

Agendas de género en las campañas presidenciales de 2018 en México

This article analyzes gender related issues posed by three presidential candidates nominated by partisan coalitions in the 2018 elections. The coalition’s electoral platforms were reviewed and, drawing from journalistic information, a data base was constructed in which all of Lopez Obrador’s, Meade’s and Anaya’s events during their campaigns were registered. The main conclusion is that, in their agendas, the topics of gender from a distributive approach that reinforces traditional roles for women are predominant. In a parallel way, various feminist and lgbt+ collectives presented agendas for equality, which have been as a consequence represented by alternative communities.

Recovering Best Statistical Guarantees via the Empirical Divergence-Based Distributionally Robust Optimization

We show that using empirically defined Burg-entropy divergence balls to construct the DRO can attain such guarantees. These balls, however, are not reasoned from the standard data-driven DRO framework because, by themselves, they can have low or even zero probability of covering the true distribution. Rather, their superior statistical performances are endowed by linking the resulting DRO with empirical likelihood and empirical processes. We show that the sizes of these balls can be optimally calibrated using χ2-process excursion. We conduct numerical experiments to support our theoretical findings.

OOESAlgorithm.jl: a julia package for optimizing a linear function over the set of efficient solutions for biobjective mixed integer linear programming

AbstractWe present OOESAlgorithm.jl, a package for optimizing a linear function over the efficient set of biobjective mixed integer linear programs. The proposed package extends our recent study (see Sierra‐Altamiranda and Charkhgard [INFORMS Journal on Computing, https://doi.org/10.1287/ijoc.2018.0851]) by adding two main features: (a) in addition to CPLEX, the package allows employing any single‐objective solver supported by MathProgBase.jl, for example, GLPK, CPLEX, and SCIP; (b) the package supports execution on multiple processors and is compatible with the JuMP modeling language. An extensive computational study shows the efficacy of the package and its features.
