Full textAbstract:
This article builds on existing theories of self-presentation and self-identity through a study into the behaviour of fashion influencers who position themselves as Scottish on Instagram. Fourteen interviews were carried out with Scottish fashion influencers who were asked to reflect on their online identity. The interaction between the offline and online self is explored, where national identity and a sense of place are recognized as important attributes of self-identity in an offline setting and participants were sampled on the basis that they were projecting this as a key component of their online self. All were found to be seeking to convey an ideal identity on Instagram; this involved curating particular aspects of their offline style and showcasing these online. The issue of authenticity was complex, and a spectrum of identity evolution on Instagram is observed and reflected on. The most career-minded participants tended to portray themselves in a more one-sided manner and were most strongly influenced by a sense of their audience. In contrast, the participants who were less career-minded tended to explore more freely with their online self and were influenced most strongly by internal factors.

Full textAbstract:
The dominance of online social networking sites (SNSs) sparks questions and concerns regarding information privacy, online identity, and the complexities of social life online. Since messages created by a technology’s purveyors can play an influential role in our understanding of a technology, we argue that gaining a complete understanding of the role of social media in contemporary life must include qualitative exploration of how public figures discuss and frame these platforms. Accordingly, this article reports the results of a discourse analysis of Facebook founder and CEO Mark Zuckerberg’s public language, foregrounding the evolution of his discourse surrounding Facebook’s self-definitions, the construction of user identity, and the relationship between Facebook and its users.

Full textAbstract:
The paper aims to analyze, on one hand, the evolution and interpretation of graffiti and street art phenomenon in the Romanian capital, Bucharest, and at international level, and on the other hand how this subculture is related to aspects of culture and heritage. The analysis of the evolution followed by graffiti and street art in Bucharest is doubled by the investigation of the messages transmitted in relation to the national and local culture and history, as street art may be seen as an efficient tool contributing to local cultural identity building. The methods used rely on a complex approach, combining observation and photos from field research, documentation, and data collection from different organizations and online communities. Street art works have various positive effects on the urban landscape, including in relation to culture and heritage in time. The results demonstrate that in Bucharest, street art contributes to highlighting mainly the key-moments and the personalities in culture and history that contribute to shaping a part of cultural identity.

Full textAbstract:
This article discusses the evolution of self-inscription from the soul-searching autobiographical narratives characteristic of personal diaries to the highly referential and indirect language articulated in today’s social media. To trace the origins of this shift, this study considers blogs of the first decade of the 21st century where traditional diary narrative started to transform into a new type of ego-text. It suggests that the spread of online quizzes and questionnaires in the beginning of the 21st century played an important role in the creation of the referential Self characteristic of today’s online rhetoric. Entering the realm of traditional ego-text, these prestructured tools replaced evident self-narration with a disguised indirect version, providing ready-made identity templates and establishing clear rules of information circulation.

Full textAbstract:
Online education is considered a modern landmark in Self-Directed Learning (SDL), but current trends place that characterization and the effectiveness of the delivery method in jeopardy. U.S. growth trends indicate increasing numbers and percentages of younger students entering virtual classrooms, compounded by wholesale shifts to online delivery in the wake of COVID-19. As the online arena transitions from working adults seeking educational access to entire undergraduate populations, online education appears to be evolving from an alternative delivery method into a ubiquitous form of higher education, thereby losing its identity as SDL and with all the pedagogical consequences such an evolution implies. Amid calls for increased student access and the continuing clamor for accountability, we examine differences in metacognitive awareness and regulation strategies in the multigenerational melting pot that has become undergraduate online education. While our findings indicate that younger students possess lower metacognitive capacity for maximizing online success and lead us to caution against wholesale implementation and its overuse for younger participants, we also offer considerations to help both faculty and institutions leverage the benefits of effective online delivery and encourage them to move beyond the stale methodologies that all too often separate motivated students from truly meaningful education.

Full textAbstract:
Purpose The purpose of this paper is to assess whether the temporal evolution of the normalized web distance (NWD) between significant terms concerning, e.g., a case of online activism can be used as a meta-data technique to measure evolution over time of, e.g., progress or decline of social empowerment. Design/methodology/approach The NWD between two terms has been identified as a quantitative measure for semantic proximity, ascertaining a defining relation between them. A trend analysis is made by performing on the internet a time window restrained series measurement of NWD of all combinations of key-terms and classifier-terms. Case defining key-terms, positive and negative discourse polarizing classifier-terms, and neutral classifier-terms for negative control need to be determined by discourse analysis of information on a targeted case. An example of NWD evolution from 1994 until 2013 is presented to measure the empowerment effects of the Wirikuta online movement on the Huichol people in Mexico. Findings The application of the NWD temporal evolution method to the Wirikuta case shows a slight but significant semantic change of the key-terms with respect to some of the positive and negative classifier-terms. The neutral classifier correctly shows no significant distance variation, as required for valid application of the method. The method provides indications for a complex image of empowerment of the Huichol identity. Research limitations/implications The accuracy of the method is limited due to short-term and between-user variability of the search tool’s page counts. More reliable access to a web-index will be required for more accurate NWD-based trend analysis. Practical implications The monitoring of temporal NWD evolution provides a potential tool for more comprehensive trend description compared to classical frequency based methods. Originality/value Trend analysis is key to internet research, to which the temporal NWD method provides an innovative contribution.

Full textAbstract:
Proto-State Media Systems explores how militant, non-state organizations create, develop, and sustain media systems in the contemporary environment. It challenges generalized applications of dominant state-based media system models by revealing how such approaches lack full explanatory power for assessing the structures and functions of media systems of groups like al-Qaeda and ISIS. Utilizing theories of constitutive discourse and online networks, as well as revised conceptualizations of proto-states and media systems, the book explores how militant proto-states can create identity-based media systems capable of attracting and sustaining online and offline loyalties. Proto-State Media Systems begins by tracing the structural evolution of the media operations of al-Qaeda over a thirty-year period and of ISIS since it emerged around the turn of the century. It then mines recurrent transhistorical and transpatial referent points in al-Qaeda and ISIS’s Arabic and English media products to identify insightful, embedded criteria for evaluating proto-state media systems. It then identifies events—both material and symbolic—associated with heightened interest levels by online users and traditional media outlets, and explores how patterned uses of multimodal appeals function to sustain viewer interest over time. It concludes by providing an integrated model for comparing proto-state media systems.

Full textAbstract:
AbstractAnalyzing and understanding software developers’ work habits and resulting needs is an essential prerequisite to improve software development practice. In our research, we utilize different qualitative and quantitative research methods to empirically investigate three underexplored aspects of software development: First, we analyze how software developers use sketches and diagrams in their daily work and derive requirements for better tool support. Then, we explore to what degree developers copy code from the popular online platform Stack Overflow without adhering to license requirements and motivate why this behavior may lead to legal issues for affected open source software projects. Finally, we describe a novel theory of software development expertise and identify factors fostering or hindering the formation of such expertise. Besides, we report on methodological implications of our research and present the open dataset SOTorrent, which supports researchers in analyzing the origin, evolution, and usage of content on Stack Overflow. The common goal for all studies we conducted was to better understand software developers’ work practices. Our findings support researchers and practitioners in making data-informed decisions when developing new tools or improving processes related to either the specific work habits we studied or expertise development in general.

Full textAbstract:
Avatars are defined as virtual representations that are controlled by a human user. Commonly, we observe avatars in video and online games, social networking sites, and virtual worlds. This chapter explores the use of avatars in the expression, exploration, and evolution of users’ identities, both online and offline. Theoretical explanations for the creation, manipulation, use, and effects of avatars are offered, including identification, transformed social interaction, and the Proteus effect. The adoption of avatars for identity expression, exploration, and change is discussed, including Turkle’s notion of fragmented selves and Nakamura’s concept of identity tourism. Research that has investigated the effects of avatars on self-perceptions and identity in various domains (such as health, marketing, finance, and environmental behaviors) is addressed. Implications and future directions for research in this area are discussed.

Social web asynchronous communication environments provide the space for content creation, idea sharing and knowledge construction within a participatory and collaborative framework that encourages online community establishment and evolution. However, community development is a long-term process and necessitates the adoption of appropriate theoretical principles to support a developmental scheme ensuring the community’s exploratory, knowledge-based and reflexively expanding character. This chapter discusses and analyses the techniques and tools used in an online course aiming to enable Greek teachers develop their pedagogical and digital skills in order to keep update, form new relationships and grow professionally. To this end, e-course design was based on formal learning principles underlying the virtual classroom activities during which a collaborative culture was built. Also, the course structure involved informal learning principles, which were integrated into social web activities implemented on weblog and wiki artefacts created and used by participants as individual and collaborative learning tools. Through the analysis of quantitative and qualitative data gathered during the study it became evident that weblogs and wikis contributed to the growth and evolution of Greek educational networked communities and that a new online identity emerged.

This chapter describes how the Islamic State (IS) used social media in sometimes innovative, sometimes less novel ways to advance its full-spectrum propaganda. The chapter takes a social psychological perspective to explain how and why the group’s social media strategy was effective, documenting IS’s ability to develop a coherent and cohesive shared social identity and brand through social media (particularly Twitter) interactions. It is argued that while IS responded to technological developments in online and social media to develop a sophisticated media strategy, at the same time, social media played an instrumental role in the development and evolution of IS itself. This chapter also offers an opportunity to critically examine methodological challenges, future research opportunities, and the conceptual implications of studying the activities of IS and other extremist groups online.

Good planning is key to the development of a successful online learning program. For online learning (as with any form of distance education), initial planning should primarily center on two issues: identifying the educational goal of the program, and identifying the practical issues of implementation. Planners must recognize that while online learning is a technology-based activity, it must be organized around clear educational goals that are strongly aligned with one or more key areas for the institution. Although educational goals will be different for each institution, this chapter suggests common tools and strategies that can be used to help identify key goals. Once goals (and accompanying objectives) are identified, practical issues of implementation must also be carefully considered. These include determining the initial investment, deciding on profitability goals, putting strong program leadership in place, creating an effective program, and identifying support needs for faculty and students.

This paper looks into the different evolution of students’ online questionnaire performance and its impact on the final examination mark. This innovative technique has been used in a group of an introductory financial accounting course with 8 online questionnaires (one per unit) in the Moodle platform. Using cluster analysis, we identify different groups of performance evolution. The evidence obtained suggests that in one of this groups a favourable test performance evolution may lead to overconfidence with the subsequent negative effect on the final examination mark. Future research with more variables and bigger samples will help identifying this student profile with a view to prevent this undesired negative effect of this teaching technique.

The primary goal of this research was to identify the role of non-linear parameter estimation in clutch torque estimation for automotive applications. The benefit of this approach in estimating parameters of a system defined by a set of differential algebraic equations (DAEs) that represents, say, clutch torque profile is investigated. In addition, online implementation, albeit at a slow rate compared to control loop rates is demonstrated. This method of analytical DAE based estimation has significant advantages over purely empirical methods in that it directly identifies the relationships between system problem variables, such as, engine speed, cross shaft angle to variable of interest, say, clutch torque, unlike, indirect approaches [1]. In addition, in contrast with time series evolution of discrete system models based on ARMAX models, this approach allows a designer to know the relationship between system parameters such as friction coefficient, clutch engagement angle, etc and the estimation process leading to better design of clutch control algorithms. However, unlike, the direct digital control methods, DAE based approaches are computationally more intensive resulting in a need for additional onboard processing. One of the goals of this initial research is to study this to identify practical analytical and numerical approaches that will lead to onboard implementation of these algorithms for truck applications, specifically in automated mechanical transmissions (AMTs) [2, 3].

Full textAbstract:
Many real-world domains are subject to a structured non-stationarity which affects the agent's goals and the environmental dynamics. Meta-reinforcement learning (RL) has been shown successful for training agents that quickly adapt to related tasks. However, most of the existing meta-RL algorithms for non-stationary domains either make strong assumptions on the task generation process or require sampling from it at training time. In this paper, we propose a novel algorithm (TRIO) that optimizes for the future by explicitly tracking the task evolution through time. At training time, TRIO learns a variational module to quickly identify latent parameters from experience samples. This module is learned jointly with an optimal exploration policy that takes task uncertainty into account. At test time, TRIO tracks the evolution of the latent parameters online, hence reducing the uncertainty over future tasks and obtaining fast adaptation through the meta-learned policy. Unlike most existing methods, TRIO does not assume Markovian task-evolution processes, it does not require information about the non-stationarity at training time, and it captures complex changes undergoing in the environment. We evaluate our algorithm on different simulated problems and show it outperforms competitive baselines.

Recently, most traditional market services have joined online service platforms. Despite the practicality achieved, such services eventually bring a large amount of data to the Web. In this sense, data analysis, data engi- neering, and data science activities have become extremely necessary. In general, they can extract extra information about systems and users, allowing the owners to produce insights and analyze patterns. Then, we propose an evalua- tion methodology to be applied in the online scenario of registration of publications and scientific productions, such as ResearchGate and Lattes Platform of CNPq. This methodology is unsupervised and divided into three main stages: (i) obtaining and representing the data; (ii) application of topic modeling; and (iii) the labeling of topics. This proposal diverges from the literature’s proposes that are based on collaborative networks and supervised techniques. We applied this methodology to a Lattes database and were able to observe the evolution of Computer Science research in Brazil. Based on this analysis, it is possible to identify the most popular and least explored research lines in order to direct public investments according to a certain interest.

Full textAbstract:
This paper presents an effective bearing fault parameter identification scheme based on evolutionary optimization techniques. Three seeded faults in the rotating machinery supported by the test roller bearing include inner race fault, outer race fault and a single ball defect. The fault related features are extracted experimentally by processing the acquired vibration signals in both the time and frequency domain. Techniques based on the power spectral density (PSD) and wavelet transform (WT) are utilized for feature extraction. The sensitivity of the proposed method is investigated under varying operating speeds and radial bearing load. In this study, the inverse problem of parameter identification is investigated. The problem of parameter identification is recast as an optimization problem and two well known evolutionary algorithms, differential evolution (DE) and particle swarm optimization (PSO), are used to identify system parameters given a system response. For online parameter identification, differential evolution outperforms particle both in terms of adaptability and tighter convergence properties. The distinction between the two methods is not distinctively obvious on the offline parameter identification problem.

Full textAbstract:
Reservoir Fluid Geodynamics (RFG) is a novel thermodynamic methodology that integrates pressure-volume-temperature (PVT), geochemical fingerprinting (GCFP) and reservoir geology with downhole fluid analysis (DFA) data to understand the evolution of reservoir fluids over geologic time. RFG enables the enhancement of reservoir description, estimation of reservoir fluid properties, and optimization of data acquisition plans. Deep-water reservoirs comprise multiple uncertainties in reservoir connectivity, viscous oil and flow assurance. This paper demonstrates the development of digital fluid sampling techniques for deep-water fields using the RFG workflow to predict fluid properties and distribution, to address compartmentalization uncertainties and flow assurance risks, as well as to redefine the well-logging program. Identifying key reservoir concerns is the first step during the implementation of the RFG workflow. Five questions define key reservoir concerns: Do optical density measurements explain the impact of biogenic methane on fluid behavior? Is it feasible to characterize baffling and fault compartmentalization? Can we predict reservoir fluid properties and assess flow assurance risks based on fluid behavior? Is it possible to identify all this in real time? How could we optimize future fluid sampling programs? The next step is to collect the available DFA data and to integrate it with the existing PVT and geochemistry datasets. This paper describes the evaluation of over 150 fluid sampling DFA measurements acquired during the operational history of a Gulf of Mexico field. Fluid behavior and optical density gradients are interpreted from a geological perspective to understand reservoir connectivity. A strong correlation between optical density and asphaltene content enables digital fluid sampling for different PVT and geochemical parameters. Lastly, a general correlation of optical density and asphaltene content is derived for multiple Gulf of Mexico oil fields. Optical density measurements support a consistent characterization of biogenic methane along the studied deep-water field, suggesting a relation to fluid migration and charging from deeper to shallower reservoirs. Likewise, optical density gradients and its integrated evaluation facilitate the identification of mass transport complex (MTC) baffles in the north part of the field and the characterization of fault compartments in the main reservoir sands. In addition, the RFG workflow reveals the difference in fluid behavior of sampled wells located in the area of a water injection project by identifying asphaltene clustering near the oil-water contact. The correlations of optical density and asphaltene content help to predict fluid properties and to estimate its uncertainty, benefiting risk assessment for asphaltenes deposits and flow assurance in deep water operations. Real time analysis of optical density measurements during fluid sampling permits the characterization of fluid properties and reservoir connectivity, optimizing future fluid sampling programs when fluid contamination reaches 10%. Ultimately, this innovative methodology conveys a general correlation to predict asphaltene content based on optical density measurements for deep-water reservoirs in the Gulf of Mexico, enabling the possibility to predict reservoir fluid properties in real time fluid sampling operations.

The emergence of computers has led to a rapid evolution of the learning environment. In recent decades, new information and communication technology tools have contributed to major changes in learning. In this way, new forms of learning have emerged, such as learning in the virtual environment (e-learning). To support online education, it was necessary to develop a whole industry. Today there are a lot of products and services on the market from which you can choose the optimal solution. In this article were analyzed two of the elearning platforms within prestigious universities in Romania, in order to identify students' opinions about their existence, the degree of utility and usability they feel, and the possibilities for their improvement for a more good absorption among beneficiary students. The results have shown that elearning platforms are seen as a plus for the student, but there are still possibilities for improvement to catch up on the technologically advanced level

[The full paper was previously published in the International Journal of Community Development & Management Studies, 3, 65-77.] Aim/Purpose: The purpose of this study is to expand the knowledge base on factors likely to impede implementation and adoption of web-based learning management systems to blend with traditional methods of lecturing in universities to cater for the next generation of learners in Africa and Eastern Cape Province South Africa in particular. Background: The shift from the industrial economies to 21st century digital and knowledge-based economies, fueled by rapid Information and Communication Technologies (ICTs) such as Internet, YouTube, Chartrooms, Skype, Social media networks and its introduction to the educational system not only resulted in a new teaching approach globally but also paved way to usher in new generation of learners (anytime, anywhere learners) in the higher education system. Despite the fact that universities and other institutions of higher education in developed countries and some Africa countries have since recognized that the 21st century global digital and knowledge-based economies evolution has ushered in the next generation of learners, and as a result have taken the necessary steps to blend the traditional method of lecturing in higher education with web-based learning management systems in order to accommodate these learners. However, in Africa not much research has been done on the readiness of higher education institutions in terms of blending web-based learning management systems with the traditional method of lecturing to cater for the next generation of learners. Methodology: Quantitative and two non-probability sampling methods, namely, quota and purposive sampling was used to investigate the technological skills of selected lecturers from universities within Buffalo City Metropolitan as one of the core component to check the readiness of their faculty for the next generation of learners. Contribution: This research will add to the growing knowledge about the blending of web-based learning management with the traditional style of lecturing in higher education in the 21st century digital economies. Findings: The results indicated that the participating lecturers need to be trained and supported in the skills of using of the ICTs and computer programs applicable to enhance web-based learning in teaching and learning environment in higher education in order to cater for the next generation of learners associated with the 21st century digital economies. Recommendations for Practitioners: Much as there is a need for increased in investment in infrastructure within higher education institutions to support teaching and learning, continuous support and training for academics to be technologically literate and also be abreast on rapidly evolving field of ICTs is paramount as it can expedite the teaching and learning process in higher education. Recommendations for Researchers: There is the need to explore in depth the other two components suggested by Mishra and Koehler that can serve as barriers for successfully integration of technology into teaching and learning by locus of knowledge. Impact on Society: The research will assist stakeholders, policy makers and agencies tasked with transforming institutions of higher learning to identify the barriers likely to hinder transformation efforts and address them accordingly. Future Research: Checking technological skills of students are critical in this context.

Full textAbstract:
This paper mainly aims to identify the psychological, affective and sociolinguistic motivations that determine the change of the basic form of an anthroponym, in our case the evolution towards a diminutive form. The research is based on a comparative analysis between the multicultural elements that influence the process of turning proper names specific to Romanian and European areas into diminutives. To illustrate the goals of our research, we will begin by classifying the anthroponyms into two main categories − conventional (official) names and unconventional names (hypocoristics). There is a certain degree of relativity regarding the use of diminutive forms of proper names in European space, as they have a twofold character in the process of naming: on the one hand, they denote feelings of affection and, on the other, a certain degree of irony. The methodology employed consists of methods and concepts specific to onomastics, psycholinguistics and sociolinguistics. The body of the paper will illustrate and analyse pieces of information and results obtained through sociolinguistic inquiry and surveys and will also introduce examples taken from online sources.

Full textAbstract:
Multi-axis machines are growing rapidly their precision and complexity with the increasing importance of machine intelligence, automation, optimization and safety. It is necessary to identify collision risks and avoid them in manufacturing otherwise production stops may cost a huge amount to the manufacturing company. This study has focused on safe trajectory generation for CNC machines especially focusing on high risked non-functional trajectories. These machines should be able to see any unwilling situation (i.e. collisions) in their vicinity and must be able to detect and react automatically in real-time for safe tool movements. Currently CAM software and some multi-axis machines are able to detect collisions but they do not have any solution to avoid such collisions automatically. The main objective is to make multi-axis machine vision system effective enough that it can see all its activities regarding collisions and can react or command automatically online as well as off-line for real and virtual productions. In presence of obstacles during manufacturing, the proposed approach will provide decisions regarding trajectory correction and improvement automatically. The proposed vision concept is able to take into account the evolution of the scene i.e. the aspects of changes to the obstacle like shape, size or presence during production. The application presented in this paper is for 2D traversal safe online trajectories generation in virtual simulated dynamic environment, which will be adapted to the real-time real machining scenarios at shop-floor by integrating it with STEP-NC technology in future.
