    Sensor networks, along with the sensorial output from their nodes, provide an information source to enhance and enrich upper layers mechanisms. The 802.21 MIH protocol provides a cross layer framework that can be extended for sensor information transport. At the same time, it creates an abstraction layer that removes hardware and software specificity from sensor nodes. On a higher level of the network stack, the XMPP protocol also provides an upper layer solution for content syndication on a platform with global access availability. We present a framework which integrates a cross-layer abstraction approach towards sensor devices of different families, while enabling the integration of media-independent sensor information into context consumers with the aim of optimizing network management, as well as application operation and usability. The work presented was also part of the first author’s MsC dissertation

DOI 10.1016/j.ipm.2015.11.002[EN] Social and expressive media represent a challenge and a push forward for research on emotion and sentiment analysis. The advent of social media has brought about new paradigms of interaction that foster first-person engagement and crowdsourced contents: the subjective dimension moves to the foreground, opening the way to the emergence of an affective component within a dynamic corpus of digitized contents created and enriched by the users. Expressive media, which play a key role in fields related to creativity, such as figurative arts, music or drama, gather multimedia contents into online social environments, by joining the social dimension with the aims of artistic creation and self-expression. Artistic creation and performance seem to be a very interesting testbed for cross-validating and possibly integrating approaches, models and tools for automatically analyzing emotion and sentiment. In fact, in such contexts the social and affective dimensions (emotions and feelings) naturally emerge (Silvia, 2005), think for instance of the visitors’ feedback to a real or virtual art exhibition, or of the audience–performance interaction (...) In light of these considerations, this special issue focuses on the presentation and discussion of a set of novel computational approaches to the analysis of emotion and sentiment in social and expressive media.Paolo Rosso has been partially funded by the WIQ–EI IRSES project (Grant no. 269180) within the EC FP7 Marie Curie People Framework and by the DIANA-APPLICATIONS – Finding Hidden Knowledge in Texts: Applications project (TIN2012-38603-C02-01).

    Intensity of natural disasters has substantially increased; disaster management has gained importance along with this reason. In addition, social media has become an integral part of disaster management. Before, during and after disasters; people use social media and large number of output is obtained through social media activities. In this regard, Twitter is the most popular social media tool as micro blogging. Twitter has also become significant in complex disaster environment for coordinating events. It provides a swift way to collect crowd-sourced information. So, how do humanitarian organizations use Twitter platform? Humanitarian organizations utilize resources and related information while managing disasters. The effective use of social media by humanitarian agencies causes increased peoples’ awareness. The international federation of red cross and Red Crescent Societies (IFRC) is the most significant humanitarian organization that aims providing assistance to people. Thus, the aim of this paper is to analyze IFRC’s activities on Twitter and propose a perspective in the light of theoretical framework. Approximately, 5201 tweets are passed the pre-processing level, some important topics are extracted utilizing word labeling, latent dirichlet allocation (LDA model) and bag of Ngram model and sentiment analysis is applied based on machine learning classification algorithms including Naïve Bayes, support vector machine SVM), decision tree, random forest, neural network and k-nearest neighbor (kNN) classifications. According to the classification accuracies, results demonstrate the superiority of support vector machine among other classification algorithms. This study shows us how IFRC uses Twitter and which topics IFRC emphasizes more. © 2021, The Author(s), under exclusive licence to Springer Nature B.V. part of Springer Nature

    1998-1999 Monitoring Strategy, Kentucky River Basin Management Unit

    Get PDF
    During the fall of 1997 and spring of 1998 about 40 individuals and more than 30 organizations and agencies provided input into the development of a monitoring strategy for the Kentucky River basin under the Kentucky Watershed Management Framework. In addition to the agencies that were able to commit resources to the monitoring effort, citizen input was sought in the design of the strategy. Citizen monitoring efforts are also providing valuable information in many portions of the state. The intent of the coordinated planning process was to carefully consider agency resources and capabilities, taking into account where and when each was conducting field work, in order to make the best use of available resources and collect the best information at the least cost. The result should be better information for watershed management and protection, decision making, and demonstration of progress in programmatic activities. Another objective of the coordinated planning effort was to take a multimedia approach by considering surface water and groundwater, water quality and quantity, biology, toxicity, fish tissue, and sediment. All media are not fully represented. A method for integrating atmospheric deposition with other data is not yet available. Groundwater sampling and data recording protocols are still being finalized. Nor does the final plan pretend to represent a fully comprehensive strategy for characterizing all resource conditions. However, the results of the planning effort do represent a significant stride toward the goal of a comprehensive multimedia watershed monitoring strategy. The overall sampling effort includes data collected from 90 of the 97 11-digit hydrologic unit code (HUC) watersheds in the Kentucky River basin. A standard set of sampling protocols was agreed to, and cross-training sessions were provided for biological collections and habitat assessments. This report provides a summary of sampling efforts along with a standard set of water quality parameters and sampling regimes that were designed around types of land use/land cover to allow maximum utilization of programmatic resources and best characterization of water quality resources. Where possible, sampling sites for the various media utilized the same sampling sites or were placed in close proximity to each other, providing multiple lines of evidence for site assessments. Information is also presented in a way that puts rotating basin monitoring (the monitoring resources progress from basin to basin under the Watershed Management five-year cycle) into context with other ongoing statewide efforts, including other locally based monitoring, prioritization, and planning

    Sustainability of Management Decisions in a Digital Logistics Network

    [EN] Globalization has given a powerful impetus to the development of international commercial activity and logistics management systems taking full advantage of cross-border networking. The solution lies at the intersection of information technologies, technical means of machine-to-machine (M2M) interaction, mobile high-speed networks, geolocation, cloud services, and a number of international standards. The current trend towards creating digital logistics platforms has set a number of serious challenges for developers. The most important requirement is the condition of sustainability of the obtained solutions with respect to disturbances in the conditions of logistics activities caused not only by market uncertainty but also by a whole set of unfavorable factors accompanying the transportation process. Within the framework of the presented research, the problem of obtaining the conditions for the stability of solutions obtained on the basis of mathematical models is set. At the same time, the processes of transferring not only discrete but also continuous material flows through complex structured networks are taken into account. This study contains the results of the analysis of the stability of solutions of differential systems of various types that simulate the transfer processes in network media. Initial boundary value problems for evolutionary equations and differential-difference systems are relevant in logistics, both for the discrete transportation of a wide range of goods and for the quasi-continuous transportation of, for example, liquid hydrocarbons. The criterion for the work of a logistics operator is the integral functional. For the mathematical description of the transport process of continuous and discrete media, a wide class of integrable functions are used, which adequately describe the transport of media with a complex internal rheological structure.The reported study was funded by RFBR according to the research projet No 20-014-00029.Barykin, SE.; Borisoglebskaya, LN.; Provotorov, VV.; Kapustina, IV.; Sergeev, SM.; De La Poza, E.; Saychenko, L.

    Assimilation of web technologies in firms’ supply chain management: A case of the Ghanaian events Industry

    Get PDF
    Thesis submitted to the Department of Management Information Systems, Ashesi University College, in partial fulfillment of Bachelor of Science degree in Management Information Systems, April 2016This dissertation examines the supply chain framework of event planning firms in Ghana, with particular reference to the assimilation of technology in the supply chain function. The research seeks to ascertain how exactly, event firms integrate technology in their supply chain and what impact technology has on their supply chain framework. An emphasis was also placed on the type of technologies used in the industry and how quick events firms are in assimilating new technologies. The undergirding theory of the work was based on a supply chain frame work proposed by Lambart ., et al (19989) and Ranganathan ., et al(2006). The methodology employed in analyzing the supply chain framework and technology assimilation included phone and Skype interviews as well as questionnaires. Emails were sent to chief executive officers of event firms and Skype interviews were set. Questionnaires were sent to those who could not have time for interviews. The findings presented in this research consist of information obtained from a qualitative study of a sample of event planning firms in Accra. This study postulates that, there exists an inefficient supply chain frame work in the Ghanaian event firms due to long communication among stake holders. The Ghanaian events industry utilizes mobile applications more than web applications; however, the number of communication prolongs the process. Cross platform applications such as facebook and instagram can be used as web applications, however, industry members choose to use them as mobile applications because of their convenience and simplicity. The supply chain of the event planning industry can be improved by using a series of cross platform applications that can help reduce the communication process among the industry stakeholders. Technology assimilation is high and Social media is the main technology stream significantly used in the industry, the social media sector can be utilized to make communication faster and easier, rendering the supply chain framework efficient.Ashesi University Colleg
