Full textAbstract:
Infrastructures support and shape our social world, but they do so in often invisible ways. In few cases is that truer than with various documents that serve infrastructural functions. This article takes one type of those documents—technical standards—and uses analysis of one specific standard to develop theory related to the infrastructural function of writing. The author specifically analyzes one of the major infrastructures of the Internet of Things—the 126-page Tag Data Standard (TDS)—to show how rethinking writing as infrastructure can be valuable for multiple conversations occurring with writing studies, including research on material rhetoric, research that expands the scope of what should be studied as writing, and research in writing studies that links with emerging fields. The author concludes by developing a model for future research on the infrastructural functions of writing.

The purpose of the article is to study the information aspects of the activities of a motor transport enterprise, to build a communication network within the enterprise, which seeks to fully satisfy the needs of society for the transportation of goods and passengers. Methodology. The study was carried out using graph theory - one of the major branches of discrete mathematics, which is widely used in solving economic and management problems. Using these methods, the minimum path in the information network is found. Results. The quality and timeliness of information coming in the forward and backward directions determines the quality of management of individual objects of the road transport system, as well as the possibility of its coordinated functioning in order to fully satisfy the needs of society for the transportation of goods and passengers. The article examines the introduction of information technologies in transport, which are used at all stages of receiving, storing, processing and transmitting information, should fully ensure the timeliness and high quality of information support when making managerial decisions at all levels of the transport system. The general principles of the construction and functioning of motor transport systems are analyzed through the prism of the information procedures implemented in them and the emerging information flows. It has been established that most of the total volume of information processed in a company can be information necessary for the management and control of logistics operations. Since the road transport system is geographically distributed, a modern specialist must master the methods of spatial analysis based on geoinformation technologies. The development of the information and communication infrastructure of a new transport company, which plans to carry out the transportation of goods by road, has been investigated. The company will provide services such as cargo transportation, freight forwarding services, cargo tracking, cargo insurance, settlement of cargo deliveries, cargo unloading and loading. For the optimal placement of the company's network, graph theory is used. An optimal communication network has been built, connecting various departments of the company, namely, the transportation department, the office, the accounting department, the economic planning department, the legal department, the mechanical department, the communications department, and the personnel department. The scientific novelty of the article is the use of the method for constructing an optimal communication network at a trucking company. The practical significance of the work is that this method can be used at any transport company that begins its activity to build communication links between any departments of the company. In this case, these connections will be optimal.

This study sought to examine stakeholder involvement and implementation of infrastructure projects in Kenya Ports Authority. The specific objectives were to examine the influence of stakeholder empowerment, stakeholder communication and stakeholder grievance management on the implementation of infrastructure projects in Kenya Ports Authority. Implementation of projects at KPA has had challenges such as unmet timelines, cost overruns, scope variations and compensation demand by the local community. Theories that anchored this study are stakeholder theory, empowerment theory, game theory and communication theory. The study employed descriptive survey research design. The cadres of target population included persons in port electrical engineering, projects development and management, civil engineering, container operations, and conventional cargo operations departments totalling to 3,336 persons. The study used stratified sampling approach and the sample size was 358 persons. A structured questionnaire, containing close-ended questions was employed as the primary tool for data collection. Validity of the instruments was ensured using content validity, construct validity and face validity. Cronbach alpha coefficient test was used to test the reliability of the instrument. Microsoft Excel software and Statistical Package for Social Scientists software were used for data analysis. Multiple Regression analysis was used to determine the relationships and significance between independent and dependent variables. Tables and charts were used in the presentation of findings. The study established that stakeholder empowerment, communication and grievance management had a positive and significant effect on project implementation. This study concluded that stakeholder empowerment increases the ability and confidence of stakeholders to make choices and decisions. Effective communication helps the organization to build positive relationships with the project stakeholders whereas management of grievances provide a way to reduce projects’ risk, provide an effective avenue for expressing concerns and promote a mutually constructive relationship towards implementation of projects. The study recommended that stakeholders be empowered by allowing them to participate in decision making. Giving them more control over what happens in their work environment through control over work tasks, work pace and freedom from supervision. Project managers should establish regular communication with stakeholders and create a positive understanding to help build effective long-term relationships with key project stakeholders. The organization should adopt a structured mechanism for management of grievances that will be known to all employees.

Vehicle ad hoc networks are usually equipped with electronic chips that store a lot of sensitive information. Stores information related to routing tables, packet, packet header information, uplink and downlink speed. Many studies emphasize on transmission delays, data redundancy, queue delays and buffer management. The existing scenario collects results while transmitting packets from the source machine to the destination machine. In the enhanced view, collect results from a remote server located in a rural area. Data was collected through a cloud-based infrastructure. In this paper, we propose a framework for message propagation and provide security to end to end semantic. The benefit of this framework is to provide correct information to the end user through cloud technology. This hybrid model is capable of facilitating communication for cellular based infrastructure. To evaluate the proposed model, we collect the results from the NS2 simulator.

Aim. The presented study aims to develop conceptual approaches to the formation of infrastructure for the innovative transformation of entrepreneurship in the digital economy, which would make it possible to optimize the management system of regional economic entities aimed at creating a favorable climate for the generation, development, and implementation of innovations in the Russian socioeconomic system.Tasks. The authors analyze conceptual approaches to the formation of a system of infrastructural support for the innovative transformation of business structures based on a comprehensive analysis of the parameters of its subsystems; substantiate priority directions for the development of regional infrastructure with a view to ensuring sustainable operation of economic entities; propose scenarios for the formation of regional infrastructure based on digital technologies for the transformation of innovation activities of companies.Methods. This study is based on the classical corporate life cycle theory, which includes mechanisms and organizational structures that facilitate the sustainable development of business structures in the digital economy. Theoretical and practical recommendations for innovation management and system analysis of the formation of competitive advantages of regional economic entities are used with allowance for current trends in the world economy and geopolitical risks.Results. Infrastructure support for the innovative transformation of business structures in the digital economy should allow for the reloading of the logistical, technological, financial, economic, informational, personnel, and communication units of the company’s integrated functioning system. Digital technologies transform system-wide, strategic, marketing, information, and communication methods of development and implementation of management decisions within regional socio-economic systems.Conclusions. Infrastructure support for the innovative transformation of business structures largely depends on the use of digital methods that allow for the implementation of information and communication platforms making it possible to optimize the organizational management structures of companies. The effectiveness of innovative transformation can be increased by accelerating and simplifying business processes; increasing the level of transparency and reliability of procedures performed on the web and implemented in business applications; structural transformations of forms of interaction with customers based on modern interfaces and access to complete information about consumer preferences; ensuring the availability of services provided on a cloud platform; achieving a high level of security of the knowledge base. Digital technologies have made the effectiveness of company management more dependent on the parameters of economic security and indicators of the quality of the information and communication infrastructure used at all stages of the functioning of the regional socio-economic system. Business communications in the global market of goods and services are accelerating and simplifying.

Full textAbstract:
The existing research on forestry infrastructure has focused on suggestions from other areas of forestry research: that forestry infrastructure should be completed and improved. However, research on forestry infrastructure is relatively rare. In the real world, there are various problems with creating forestry infrastructure, such as complex approval procedures for facility construction, irrational facility layout, insufficient funding for facility construction, and conflicts between the nature of land used for facility construction and the nature of forest land. This paper uses game theory to analyze the behavior of forest infrastructure goods suppliers. Relevant parameters related to forest area infrastructure were designed, including communication, environmental certainty, information feedback, and reward and punishment mechanisms, and experimental economics methods were used to simulate accurate behavior regarding the supply of goods. Then, the key factors that affect the provision of quasi-public goods for forestry infrastructure were studied. At the end of the paper, some targeted suggestions that distinguish rural infrastructure from general infrastructure are given.

Full textAbstract:
This article examines the relationship between the news industry and digital platforms, most notably Facebook and Google, through a political economy framework. The theory of regulatory capture suggests that regulators are prone to become captured by the businesses they oversee, whether through financial incentives (such as money transfers and revolving doors) or cognitive/cultural influence (such as advocacy and shared values). The theory was further expanded to suggest that businesses also attempt to capture non-governmental institutions tasked with scrutinizing them, such as the media. This article suggests that Google and Facebook are rapidly expanding their potential capability to do so. Alongside the forms of capture described in the literature, the most crucial element in Google and Facebook’s relationships with news organizations is the fact that they have come to provide the majority of audience for online news and are significant sources of potential growth in viewership. In addition, they equip news organizations with tools for news production, provide them with data on the reach of stories, and offer tools for analytics and insight. All this potentially amounts to a new form of capture that can be called infrastructural capture: circumstances in which a scrutinizing body is incapable of operating sustainably without the physical or digital resources and services provided by the businesses it oversees and is therefore dependent on them. This new category of capture, rooted in the dynamics of contemporary digital news markets, could pose serious challenges to the ability of news organizations to scrutinize the corporations that direct most of the traffic to their sites. Aside from potentially affecting the content of news, another important effect of compromising infrastructural autonomy to non-journalistic third-party actors might be a weakening of the legal protections that journalism benefits from.

Grounded theory is a qualitative research method widely used in social sciences. Using content analysis and CiteSpace visualization software and taking journal articles of China National Knowledge Infrastructure database from 2004 to 2017 as the analysis objects, this paper comprehensively explores the studies using grounded theory in the field of journalism and communication in the Chinese mainland. It shows that the application of grounded theory in the field of journalism and communication had a relatively late start in the Chinese mainland. However, interdisciplinary research obviously prevailed. Researches using grounded theory are not widespread, while the theory has not been fully localized. Financial support from the government has been a great help to researchers, but the researchers outside the academic circles hardly get involved in academic activities.

Full textAbstract:
The article deals with the relationship between media and transportation infrastructures and analyzes their links to the concept of mobility. It examines the assumption that infrastructure systems themselves are mobile, in the sense that they develop and have to be maintained constantly. According to such a perspective, they are to be considered not primarily as “structures,“ but as specific processes of mobilization (infrastructuring) that constitute the basis for mobility in the sense of transport and movement. Drawing on historical knowledge of transportation, it will be shown that a broad understanding of traffic as exchange, communication, and transportation has narrowed in the twentieth century, whereby the originally implied idea of transport as transformation became suppressed. Recent approaches in mobility studies, Science and Technology Studies (STS) and Actor-Network-Theory (ANT) can be combined in a fruitful way to unfold the specific dynamics of infrastructure as a process of mobilization (Callon) and technical mediation (Latour).

Full textAbstract:
Brains and computers are both dynamical systems that manipulate symbols, but they differ fundamentally in their architectures and operations. Human brains do mathematics; computers do not. Computers manipulate symbols that humans put into them without grounding them in what they represent. Human brains intentionally direct the body to make symbols, and they use the symbols to represent internal states. The symbols are outside the brain. Inside the brains, the construction is effected by spatiotemporal patterns of neural activity that are operators, not symbols. The operations include formation of sequences of neural activity patterns that we observe by their electrical signs. The process is by neurodynamics, not by logical rule-driven symbol manipulation. The aim of simulating human natural computing should be to simulate the operators. In its simplest form natural computing serves for communication of meaning. Neural operators implement non-symbolic communication of internal states by all mammals, including humans, through intentional actions. The neural operators that implement symbol formation must differ, but how is unknown, so we cannot yet simulate human natural computing. Here, I propose that symbol-making operators evolved from neural mechanisms of intentional action by modification of non-symbolic operators. Both kinds of operators can be investigated by their signs of neuroelectric activity. I propose that the postulated differences should be sought by classification of the spatial textures of the signs in EEG recorded from the scalp overlying those cortical structures unique to humans in the brain that I designate as koniocortex, while the subjects are engaged in elementary arithmetic operations.

Full textAbstract:
In this article, I argue that technical reporting and documentation processes function to mitigate uncertainty and enable complex systems in the endeavor of big science. The argument draws on two years of field research investigating technical reporting and documentation processes at a federally funded supercomputing center dedicated to scientific research. A central question the study sought to answer was, “How does one build a new supercomputer?” One of the answers that emerged is that supercomputers are built by the genre assemblages of documents that mitigate financial, political, and technological uncertainties, and their attendant risks, that are inherent to technoscientific cutting-edge enterprises. Given their centrality, these genre assemblages function as essential infrastructure for the U.S. national laboratory system and for big science endeavors in general. In conclusion, this article argues that documentation that mitigates uncertainty serves an important infrastructural function for organizational life more generally.

This article presents a combination of known models and system design techniques that result in an architectural framework that is predictive. The article also provides a methodical recommendation that develops the way defense of a cyber critical infrastructure can be most effective. Firstly, historical background has been provided to motivate the current political theme, followed by modeling theory that has been published. Classical systems engineering foundations are reviewed to adapt modeling environment to the current cyber conflict problem in a way that allows a systems owner to posture most effectively against anomalies across the network of communication nodes. The implication of the model presented in the article is that a protection posture can be estimated, and can quickly turn into a balanced engagement between the attacker and defender. When optimized within decision algorithms, data will exist to illuminate what process can be implemented in defense. Using classical systems engineering fundamentals, modeling simulation, and proven mathematical approaches, this research seeks to support such implementation.

Purpose The purpose of this paper is to verify the development of economic activities in rural areas in terms of their public infrastructural equipment. Design/methodology/approach As a case study, the Polish rural areas were selected. A two-stage survey was conducted in 2015. The first stage involved entrepreneurs from rural areas. The second stage of survey was data collection for rural areas regarding economic activity and infrastructural equipment. In total, 121 objects (communes) were selected. The multicriteria analytic hierarchy process (AHP) method was used for the analysis. Findings The results demonstrate that for each kind of business, communication accessibility is the most important criterion. By contrast, environmental awareness and concern for the environment is the least important element for pursuit of the economic activity in rural areas. Research limitations/implications Limitations are connected mainly with the applied AHP method. The number of the comparable elements at the same hierarchy level is limited due to practical purposes. In addition, an assumption of full comparability of elements (criteria and alternatives) in the hierarchy model can be discussed. Furthermore, data quality and availability limit the scope of the empirical work. This study is a major simplification of reality modeling, but it gives practical benefits by simplifying the decision support procedure. Practical implications The findings of this paper contribute to the advancing theory of local development, with public infrastructure being one of its basic elements (factor of production). This paper explores the importance of physical infrastructure for different economic activities, and thus offers theoretical insights in two areas. First, this paper indicates the uneven weight of each infrastructure element for the various business sectors. Second, based on the collected data, this study also contributes to the literature, by using the AHP method to explore the relationships between infrastructural equipment and economic activity in rural areas. As the practical implication for local and regional development policies, this study indicates, that the most important criterion for each kind of economic activity is communication accessibility. This kind of public investment should be undertaken primarily to support entrepreneurship, especially in rural areas. Originality/value The uniqueness of the method lies in assumption about the uneven weights of infrastructure elements and therefore their impact on the process of ranking the objects (rural areas). The weight of individual infrastructure elements will vary depending on the kind of economic activity; therefore, the way of ordering will also be different for each economic activity.

The Cipeundeuy Village Government runs the Village Financial System, but the implementation still has several problems, including lack of facilities and infrastructure, lack of human resources and communication capabilities that are not going well. The purpose of this research is to find out how to implement the Village Financial System (SISKEUDES) Policy in Cipeundeuy Village. This study uses the theory of the implementation of Van Horn and Van Metter in Agustino (2014). The method used is descriptive qualitative. Data collection techniques used were interviews, observation, and documentation. Analysis of the data used is the Hubberman model in Mukhtar (2017). The results showed that the implementation of the use of siskeudes has not gone well. This can be seen from the lack of infrastructure, lack of human resources and communication capabilities that are not going well. Suggestions that can be given are the fulfillment of supporting facilities, there must be a shared desire to run the siskeudes and improve and strengthen communication patterns.

Full textAbstract:
In the context of the incessant development of sustainable energy and ICT (Information and Communications technology) in power systems, power system becomes more and more intelligent, efficient and economic. However, using electrical infrastructure carrying information communication causes complexities in modeling and simulating. To overcome the problem of modeling, a new approach based on scale invariance theory, scale invariance, is presented in many papers and in various fields. Scale invariance method shows a strong link between a network topology and its performances through a coefficient exponent. In this paper we propose to use this method for modeling power line communication by considering only the input impedance of system. This approach will be tested for not only a general case study but also for an opened circuit without attenuation and bruit. The result is compared with the classical method.

Full textAbstract:
In recent years, interval-valued Pythagorean fuzzy number is playing a more and more important role in decision management. It is a more effective and powerful tool to handle fuzzy information in decision problems. The multicriteria decision-making theory has been widely used in solving practical problems, such as the risk assessment of financial investment, engineering and construction, medical and health care, and information security. The main purpose of this paper is to apply a new interval-valued Pythagorean fuzzy decision-making method to practice and to analyze and solve the problem of wireless communication infrastructure. In this paper, a new interval-valued Pythagorean fuzzy ranking method, extending scope of application of the VIKOR method to interval-valued Pythagorean fuzzy set, is proposed. In order to adapt to actual needs, subjective and objective weights are combined to solve decision-making problems to enhance its practicality, validity, and effectiveness. An example of wireless communication infrastructure problem is provided to illustrate the rationality of this method and verify its advantages.

Full textAbstract:
Device-to-device (D2D) communication is a technique for direct communication between devices without going through a base station or other infrastructure. D2D communication technology has the advantages of improving spectrum efficiency and reducing transmission delay and transmission power. In D2D communication systems, orthogonal frequency-division multiple access (OFDMA) is widely used to maintain similarities with cellular communication systems and to secure transmission distance. OFDMA allows flexible and efficient use of frequency resources by allocating sub-channels independent to each user. In this paper, we consider a D2D overlay system that uses different sub-channels for cellular and D2D communications. In theory, the signals on different sub-channels of an OFDMA system are orthogonal and not interfered with each other. However, in a D2D communication system, which operates in a distributed manner, there is non-negligible interference from other sub-channels because of in-band emissions. In this paper, we address the performance degradation resulting from the interference from other sub-channels for OFDMA-based D2D group-casting systems. We consider three different scenarios of D2D relay, and we find the relay position that minimizes the outage probability. The simulation and analytical results show that the optimal location of a relay can be considerably different according to the source location and the target scenario.

In Norway, the focus on interoperability and communication across healthcare practices has increased the need to connect ICT portfolios at different levels of healthcare, into large-scale information infrastructures (II). Governing healthcare practices is exceptionally complex, due to the diverging goals and policies of the heterogeneous actors involved. Establish well-functioning ICT governance organizations to handle these large infrastructures is therefore important. Using information infrastructure theory, and governance literature from the IS field, this paper contributes with empirical insight to the longitudinal and political process of establishing ICT governance in a healthcare context, reporting from one of Norway's largest health ICT projects, situated in the North Norway Regional Health Authority in 2012–2016. Our focus was on the following research questions: How does organizational politics shape the process of establishing an ICT governance organization in a heterogeneous healthcare environment, and what does it take to establish such ICT governance organization?

It may be well said that the most used indicator of the quality of any technical system is reliability. Basically, this indicator shows the probability of proper technical system functioning within certain time period and under given operating conditions. To ensure that a system under construction possesses adequate given pre-defined characteristics and reliability indicators, it is necessary to plan the reliability and apply suitable methods when new technical systems are developed. Road represents an elementary traffic subsystem, as well as a technical subsystem, constructed by the society in order to meet the communication needs. Its purpose is to enable traffic system functioning. If a road is seen as a system, one can observe the features determining the structure and the principal on which its function is based. The road functioning itself is characterized by a variety of features, the most important being the management characteristic and specific social interest, categorization structure, and roadway condition. To enable smooth and safe traffic, roads should be of prescribed technical and usage levels. Reference is made specifically to road maintenance in the Primorje-Gorski Kotar County.

Abstract This article assumes a media system perspective on the local news media structure in Norway, using a dataset of 847,487 news articles collected from 156 Norwegian news outlets in 2015–2017. Using a series of hypotheses, the analysis uses Latent Dirichlet Allocation (LDA) topic modelling to ascertain to what extent local journalism meets community information needs through infrastructure, output and performance. The analysis finds that the size of the publisher and the size of the community covered matter more for hard news coverage than regulatory factors. To that end, the results indicate that the Norwegian local media system is somehow shaped by the geography of the political landscape. The results and their contributions are discussed in light of media systems theory and local journalism structures.

The purposes of the current study are (1) to conceptualize and test a social networking service (SNS) dependency measure and (2) to propose and test a general model of the effect of SNS dependency on online and offline interpersonal storytelling. This study is theoretically guided by media system dependency theory and communication infrastructure theory. Computer-assisted personal interviews (CAPI) were conducted with 477 SNS users aged 19–59 in Seoul in October of 2012. Confirmatory factor analyses results showed that our SNS dependency measure was valid and reliable. The results also confirmed that SNS dependency had direct effects on individual users’ levels of engagement with interactive activities on SNSs and indirect effects on offline interpersonal storytelling.

The technological revolution that has changed from analog to digital creates new challenges and opportunities, particularly when referring to the communication perspective. This study discusses communication through digital media and its dynamics in Indonesia. It comprehensively examined Ruangguru, the biggest online learning platform in Indonesia. This paper uses a qualitative descriptive approach with a case-study method. It is aimed to analyze Ruangguru’s online learning communication patterns using the social presence theory in the dimensions of social context, online communication, and interactivity. The result of this study reveals many advantages offered by online learning. Nevertheless, online learning can not fully replace conventional learning, especially when viewed from the low dimensions of social context. In the online communication dimension, Indonesia is still hampered by technical problems, both from technology infrastructure and the readiness of teachers and students.

Full textAbstract:
Real-time traffic signal control presents a challenging multiagent planning problem, particularly in urban road networks where, unlike simpler arterial settings, there are competing dominant traffic flows that shift through the day. Further complicating matters, urban environments require attention to multimodal traffic flows (vehicles, pedestrians, bicyclists, buses) that move at different speeds and may be given different priorities. For the past several years, my research group has been developing and refining a real-time, adaptive traffic signal control system to address these challenges, referred to as scalable urban traffic control (Surtrac). Combining principles from automated planning and scheduling, multiagent systems, and traffic theory, Surtrac treats traffic signal control as a decentralized online planning process. In operation, each intersection repeatedly generates and executes (in rolling horizon fashion) signal-timing plans that optimize the movement of currently sensed approaching traffic through the intersection. Each time a new plan is produced (nominally every couple of seconds), the intersection communicates to its downstream neighbors what traffic it expects to send their way, allowing intersections to construct longer horizon plans and achieve coordinated behavior. Initial evaluation of Surtrac in the field has demonstrated significant performance improvements, and the technology is now deployed and operating in several U.S. cities. More recent work has focused on integrating real-time adaptive signal control with emerging connected vehicle technology, and exploration of the opportunities for enhanced mobility that direct vehicle (or pedestrian) to infrastructure communication can provide. Current technology development efforts center on vehicle route sharing, smart transit priority, safe intersection crossing for pedestrians with disabilities, real-time incident detection, and integrated optimization of signal control and route choice decisions. This article provides an overview of this overall research effort.

Abstract As potentially eligible recipients continue to increase in number, understanding service system utilization and barriers can help ensure very old adults can access support from their communities when needed. A communication disjuncture between seniors and community-based service providers was revealed through a multi-year, county-wide older adult needs assessment utilizing data from 1,870 individuals. In response, officials convened a post assessment team that formed the three-person Community Advisory Group (CAG, all ≥69 years) who participated in this community-based participatory research (CBPR) study. This applied, qualitative study, guided by an ecological health communication research framework, conducted multilevel examinations of interactions among older adults and their social environment. Twenty in-depth, face-to-face, semi-structured interviews (mean = 82.5 years) were conducted based on a critical threshold of understanding achieved via researcher immersion in the community preceding this study, data collected, and CAG insight revealed through collaborative analysis. Communication Infrastructure Theory helped to reveal how participants’ diminishing social network interrelated with the communication environment acted to impede connections to services. In addition to utilization impediments, enabling elements of the communication infrastructure were identified so those resources might be leveraged to bridge the senior-provider divide. Findings from this study suggest new outreach approaches for connecting to older adults through their communication ecology. The findings add to the growing convergence of evidence that calls for improved communication with older adults to minimize poor interactions that hinder accessing resources that may enhance their social, emotional, and physical well-being.

Language, humans’ most distinctive trait, still remains a ‘mystery’ for evolutionary theory. It is underpinned by a universal infrastructure—cooperative turn-taking—which has been suggested as an ancient mechanism bridging the existing gap between the articulate human species and their inarticulate primate cousins. However, we know remarkably little about turn-taking systems of non-human animals, and methodological confounds have often prevented meaningful cross-species comparisons. Thus, the extent to which cooperative turn-taking is uniquely human or represents a homologous and/or analogous trait is currently unknown. The present paper draws attention to this promising research avenue by providing an overview of the state of the art of turn-taking in four animal taxa—birds, mammals, insects and anurans. It concludes with a new comparative framework to spur more research into this research domain and to test which elements of the human turn-taking system are shared across species and taxa.

Full textAbstract:
Anti-corruption efforts from the grassroots that make use of digital media to hinder corrupt behaviors are flourishing worldwide. In many cases, these efforts see activists interact with big data along with other types of data. They do this in the framework of broader communicative infrastructure in which activists create, employ, and spread big data to support their struggles. As well, they do so differently, according to a diverse range of activists’ local situations across the world. The article uses examples of anti-corruption efforts in Brazil, India, and Spain to illustrate how the grounded theory method might help researchers to produce knowledge that escapes a universalistic and global vision of datafication detached from activists’ lived and local experiences. The article first briefly outlines what grounded theory is, the main steps in a grounded theory study, and its applications in media and communication studies. It then moves to a broader discussion of two relevant elements of grounded theory – sensitizing concepts and theoretical sampling – in taking into consideration data-enabled activism as an emergent phenomenon that might take many shapes. Then, it considers the emphasis on the situation in which data-enabled activism spreads out through a brief discussion of one relevant development of grounded theory, which is situational analysis, to solve the tension between the global and the local in data-enabled activism.

MANETs are self configuring networks that are formed by a set of wireless mobile nodes and have no fixed network infrastructure nor administrative support. Since transmission range of wireless network interfaces is limited, forwarding hosts may be needed. Each node in a wireless ad hoc network functions is as both a host and a router. Due to their communication type and resources constraint, MANETs are vulnerable to diverse types of attacks and intrusions so, security is a critical issue. Network security is usually provided in the three phases: intrusion prevention, intrusion detection and intrusion tolerance phase. However, the network security problem is far from completely solved. Researchers have been exploring the applicability of game theory approaches to address the network security issues. This paper reviews some existing game theory solutions which are designed to enhance network security in the intrusion detection phase.

Through the domestication framework and actor-network theory, findings showed a unique overlay of actors influencing acquisition and adoption of apps, including: dependent users, “warm-gatekeepers,” mobile phone shops, and Facebook. Mediators such as Android skins, language skills, and other factors (mobile data pricing and network infrastructure) impact the relationships between these actors. Together, the impact of mediators on actor relationships highlighted a filtered means many users adopted to acquire new apps, a “two-step access” model of acquisition. This article traces how users acquire apps given this network of actors, following their journey and how they overcome challenges and limitations in their social and technological landscape.

As the United States grapples with increasingly partisan media and affective polarization, how do cultural and political fault lines filter into residents’ daily lives, and how are they navigated? This case study of a region within a red state uses a communication infrastructure theory framework to examine how this political context affects residents’ relationships with media and their larger community storytelling networks. Through a series of focus groups, story diaries, and interviews with residents and local journalists, it explores whether shared communication resources remain and the potential for creating spaces for dialogue across political and demographic divides. Findings illustrate how residents negotiate interpersonal relationships, community spaces, and local and national media in a polarized communication context. The study highlights the importance of recognizing place-based identities and media representations to facilitate trust in journalism and points to possible responses for local news and community engagement.

This paper is focused on the channel modeling techniques for implementation of narrowband power line communication (NB-PLC) over medium voltage (MV) network for the purpose of advanced metering infrastructure (AMI). Three different types of models, based on deterministic method, statistical method, and network parameters based method are investigated in detail. Transmission line (TL) theory model is used to express the MV network as a two-port network to examine characteristics of sending and receiving NB-PLC signals. Multipath signal propagation model is used to incorporate the effect of multipath signals to determine the NB-PLC transfer function. A Simulink model is proposed which considers the values of MV network to examine the characteristics of NB-PLC signals. Frequency selectivity is also introduced in the impedances to compare variations and characteristics with constant impedances based MV network. A state-of-the-art mechanism for the modeling of capacitive coupling device, and impedances of low voltage (LV) and MV networks is developed. Moreover, a comparative analysis of TL theory and multipath signal propagation models with the proposed Simulink model is presented to validate the performance and accuracy of proposed model. This research work will pave the way to improve the efficiency of next-generation NB-PLC technologies.

Recently, cognitive radio and smart grid are two areas which have received considerable research impetus. Cognitive radios are intelligent software defined radios (SDRs) that efficiently utilize the unused regions of the spectrum, to achieve higher data rates. The smart grid is an automated electric power system that monitors and controls grid activities. In this paper, the novel concept of incorporating a cognitive radio network as the communications infrastructure for the smart grid is presented. A brief overview of the cognitive radio, IEEE 802.22 standard and smart grid, is provided. Experimental results obtained by using dimensionality reduction techniques such as principal component analysis (PCA), kernel PCA, and landmark maximum variance unfolding (LMVU) on Wi-Fi signal measurements are presented in a spectrum sensing context. Furthermore, compressed sensing algorithms such as Bayesian compressed sensing and the compressed sensing Kalman filter is employed for recovering the sparse smart meter transmissions. From the power system point of view, a supervised learning method called support vector machine (SVM) is used for the automated classification of power system disturbances. The impending problem of securing the smart grid is also addressed, in addition to the possibility of applying FPGA-based fuzzy logic intrusion detection for the smart grid.

In critical infrastructures like airports, much care has to be devoted in protecting radio communication networks from external electromagnetic interference. Protection of such mission-critical radio communication networks is usually tackled by exploiting radiogoniometers: at least three suitably deployed radiogoniometers, and a gateway gathering information from them, permit to monitor and localise sources of electromagnetic emissions that are not supposed to be present in the monitored area. Typically, radiogoniometers are connected to the gateway through relay nodes. As a result, some degree of fault-tolerance for the network of relay nodes is essential in order to offer a reliable monitoring. On the other hand, deployment of relay nodes is typically quite expensive. As a result, we have two conflicting requirements: minimise costs while guaranteeing a given fault-tolerance. In this paper, we address the problem of computing a deployment for relay nodes that minimises the overall cost while at the same time guaranteeing proper working of the network even when some of the relay nodes (up to a given maximum number) become faulty (fault-tolerance). We show that, by means of a computation-intensive pre-processing on a HPC infrastructure, the above optimisation problem can be encoded as a 0/1 Linear Program, becoming suitable to be approached with standard Artificial Intelligence reasoners like MILP, PB-SAT, and SMT/OMT solvers. Our problem formulation enables us to present experimental results comparing the performance of these three solving technologies on a real case study of a relay node network deployment in areas of the Leonardo da Vinci Airport in Rome, Italy.
