Understanding why organizational stakeholders choose to communicate company-relevant information to others in their network is an area of ongoing interest to both academics and practitioners. This dissertation advances internal marketing literature by conceptualizing employees as internal customers and modeling their communication behaviors as value exchanges. Communication choices were hypothesized to be based on the perceived values of available communication options, deriving influence from both employee internal characteristics and situational variations in the decision context. This framework was applied and analyzed within two contexts. The first essay examined the dynamics of internal customers’ propensity to “blow the whistle” on peer misconduct to organization higher-ups. These studies revealed that employees disclosed or withheld firm-damaging information based on the social and functional value characteristics presented in available communication options. The second essay examined the motivating factors behind front-line employees’ decisions to convey brand information to external customers. These studies showed that employees were driven by factors affecting the perceived intrinsic value of engaging in discussions about the brand topic, as well as the perceived extrinsic value of rewards expected as a result of having such customer interactions. Overall, this dissertation suggests that companies may enable the diffusion of company information by creating conditions that increase employees’ perceived value of engaging in brand communications. / Business Administration/Marketing

The present study is an investigation of a recent phenomenon, the creation and maintenance of a student-centered online community using Line, a Web 2.0 mobile messaging (MIM) application. In recent years, mobile instant messaging has become the most widely utilized form of social media (Clement, 2019a), and has been increasingly used by students to interact about schoolwork (e.g., Cetinkaya, 2017; Bouhnik & Deshen, 2014; Tanaka, 2014). With the ubiquity of mobile technology use amongst students, how interactions in student-centered online groups contribute to the achievement of academic goals warrants further research. Therefore, this study had three purposes. The first purpose was to utilize Wenger’s (1998) community of practice framework to investigate whether an online group formed by the students could evolve into an academic community of practice. A second purpose was to analyze online interactions through the lens of uses and gratifications theory (Katz, Blumler, & Gurevitch, 1973) to discover the specific academic uses of MIM valued by the participants. Furthermore, the affordances (Gibson, 1977) that made the application amenable to academic purposes were investigated. The third purpose was to further analyze online interactions to uncover the specific ways in which the practices of the online academic group contributed to and conflicted with the achievement of course objectives. A case study approach (Yin, 2014) was used to provide a thick descriptive account of the online group and achieve the objectives of the study. The 12 participants in this study were members of an intact EAP course, which was part of an English-medium economics curriculum at a private Japanese university. The main source of data were two online groups created using the Line application, one group consisting of all members of the class and the other a group of four students created to work on the course project. Other sources of data included online documents saved to Google Drive, a survey, interviews, and course materials. Data from all sources were coded and analyzed first inductively, using codes from the three frameworks used in the study, and then inductively, to discover any other themes that emerged from the data. The analysis suggested that the online group created by the participants evolved into an academic community of practice. There was evidence of a focused academic domain because the vast majority of online posts dealt directly with course content. Moreover, interactions revealed the development of trust, reciprocity, and commitment, all key components of mutual engagement. Various group practices also emerged that supported students in their coursework and contributed to group learning. A key factor in community formation was attributed to the Line application meeting the academic needs of students. Key gratifications associated with the needs of the students included online interaction with a closed group, convenience, quickness, retrievability, information sharing, and emotional support. The affordances that enabled these gratifications to be obtained were selective connectivity, context-free access, asynchronous/synchronous communication, information aggregation, and multi-user content creation. Further analysis of the online interactions supported by these affordances showed that the prominent group practices directly supported course objectives. However, there were several conflicts associated with the use of MIM, such as problems with the constant flow of messages, unequal levels of contribution, and academically questionable activities. Finally, a summative analysis led to the creation of a model that demonstrated the relationships between learning objectives, student academic needs, gratifications, and affordances in the formation of a community within the context of a traditional university course. / Applied Linguistics

While digital mediation can facilitate some aspects of communication, such as increasing scope and access to communicative possibilities, those gains are overwhelmed by the challenges of digital mediation to support empathy.The ubiquity of our digital existence throughout much of the developed world has, in a relatively short time, had a profound impact on human communication. Time spent online and in front of a screen has increased exponentially during the last three decades. This has led to a great deal of interpersonal communication becoming digitally mediated. From luddites to web developers, users of digitally mediated communication (DMC) often find it necessary to participate in discourse that utilizes these technologies. In this project, I assess user experiences with DMC on interpersonal discourse to gain insight into user perceptions of empathic communication in the form of Short Message Service (SMS) text messaging. I employ survey and interviews protocols on a sampling of undergraduate students on one campus of a regional community college. While some think that DMC opens new spaces for social connections, others believe that DMC has a negative impact on our social relations by challenging empathetic connections between interlocutors. I hypothesize that empirical evidence will support this second view. Results of this investigation may be used to determine the conditions under which empathy is diminished in DMC and help us consider improved protocols for employing this ever-expanding mode of interpersonal communication. This study is unique in that it attempts to evaluate empathy, a concept that is challenging to define, describe, and measure. Hence, questions used in the survey paid attention to perceptions of empathy and survey takers' sentiments regarding the expression of empathy in text-messaging.

This thesis deals with messaging and integration of third-party JMS providers into JBoss application server. The aim of the thesis was to design and implement a general-purpose testsuite to verify the proposed integration. First requirement was to get familiar with key technologies for integration including Java Message Service, Java EE Connector Architecture, selected JMS providers and JBoss AS. Specific procedures of integration were designed and described for JMS providers Apache ActiveMQ, IBM WebSphere MQ and Red Hat MRG Messaging. The testsuite implemented to verify the functionlity of the integration focuses on four areas - transactions, clustering, high availibility and performance. The process of testing was automated using continuous integration tool Jenkins. Finally the test application was used to evaluate functionality of the integration and compare different JMS providers and various versions of JBoss AS.

The aim of this thesis is to describe, by means of compounding disciplines of Computer Mediated Communication and Human-Computer Interaction, how interpersonal communication is transformed by the read recepit function which occurs in contemporary Instant Messaging applications. Besides the impact of the function itself on interpersonal communication, this thesis also explores the effect of other Awareness Cues on its acceptance and interpretation.

Doctor of Philosophy / Department of Psychological Sciences / Laura A. Brannon / The current research investigated strategies to reduce cell phone use while driving. Anti-distracted driving campaigns, which typically communicate risk information and target driver behavior, may produce limited effects because people tend to underestimate their risk from this behavior (e.g., Schlehofer et al., 2010). Study 1 compared the effects of messages targeting drivers to messages targeting non-drivers in order to examine the potential of discouraging people from having cell phone communication with others who are driving. Some anti-distracted driving campaigns have emphasized the potential harm to both the driver and others, but whether one approach (self-oriented or other-oriented messaging) is more persuasive than the other has not been examined empirically. Study 1 compared messages that were self-oriented, other-oriented, or neutral in terms of who could be affected by cell phone use while driving. Although cell phone use while driving generally is perceived as dangerous, people may make justifications for engaging in the behavior on at least some occasions, and these justifications may override the influence of risk knowledge on behavior. Consistent with inoculation theory (McGuire, 1961), if given the opportunity to practice refuting these justifications in a controlled setting, people will be more likely to defend themselves against justifications to engage in cell phone use while driving. Thus, Study 1 tested the prediction that participation in an inoculation task would reduce the likelihood of cell phone use while driving. Results from Study 1 suggested an advantage of targeting non-driving participants of cell phone conversations to enhance efforts for reducing on-the-road cell phone use. Study 1 also demonstrated a positive effect of inoculation, but primarily for behavior of non-driving participants of cell phone conversations. In addition to overconfidence in ability to avoid risk, habitual tendencies also may impede the influence of risk communication campaigns (Bayer & Campbell, 2012). Study 2 investigated the potential of mindfulness-based and implementation intentions techniques for helping people overcome habitual responses to their cell phone when doing so is inappropriate or inconvenient. Results indicated that pairing mindfulness-based training with risk information may be significantly more effective than risk information alone at inhibiting inappropriate cell phone use.

Ο εικοστός πρώτος αιώνας θα μπορούσε εύκολα να χαρακτηριστεί ως τεχνολογικός αιώνας μιας και τα νέα δεδομένα μαρτυρούν αύξηση της χρήσης του ηλεκτρονικού υπολογιστή, του Διαδικτύου και κατ’ επέκταση των κοινωνικών δικτύων. Κι αυτό γιατί η επισκεψιμότητα των κοινωνικών δικτύων και η συμμετοχή σε αυτά, τόσο σε παγκόσμιο όσο και σε ελληνικό επίπεδο εκφράζεται ιδιαίτερα υψηλή.

This is because the traffic of social networks and participation in them, both globally and also in Greece is expressed in very high level. Social networking on the Internet and social networks on the web helped to change the structure and development of the World Wide Web. This diploma will study social networks, their structure, the services they provide and their supporting technologies. Moreover, the ways that knowledge management is achieved through social networks will be presented and some tools for qualitative and quantitative growth will be analyzed. The structure of the thesis is as follows: The first chapter defines the concept of personalization, social networking and presents the following social networks: My Space, Bebo, Linked In, Facebook, Twitter, YouTube.com, Google+, Friendster, Hi5, Sobees, Zokem, Gowalla, Qik. The second chapter presents the analysis of social networks and the metrics of social network analysis (measurements with respect to the nodes, measurements regarding graphs). The third chapter refers to the features of social networks, to key roles within social networks (too central role, the role of silent hero role, intermediary role, role bridging remote teams, too peripheral role), services, language properties and applied fields (ex. education, business, government, medical applications, acquaintances). The fourth chapter describes the hazards posed through social networks. The use of personal data in different ways, the seduction of children by creating false profiles, identity and account information theft, transmission of viruses, spamming, 6 and personalized phishing attack are some of the dangers presented by the use of social networks. The fifth chapter presents in more detail the social network Facebook, the features and technologies implemented. This refers to how the Chat service is implemented using the protocol XMPP, Jabber ID. Reference is also made to the communication protocol IPv6, the addressing, the improvements over the IPV4 etc. The sixth chapter discusses the software for the analysis of social networks. It presents some quantitative and qualitative measurement of social networks such as UCINET, Pajek, NetMiner II, STRUCTURE, MultiNet, and StOCNET.

<p>This research concerns exploiting knowledge of the user's environment (i.e., context information) to enrich a user's communication making it more personal, by ensuring that the user receives only relevant messages and calls in his/her current context, and to facilitate more opportunities for communication interactions with people that are in the same context and that share the same interests as this user. We describe in this licentiate thesis the concepts of context-addressed messaging and context-aware session control that enable users to: (1) send messages to others based on their context, rather than their network address and (2) to initiate, adapt, and terminate user's communication sessions based on this user's current context, respectively. These concepts address questions such as: how to discover, select, and switch to an optimal communication means to meet varying user, contextual, communication, and device resource requirements and preferences. A key to solving these problems is to create a representation of the user's context-dependent preferences and to process the user's context-dependent preferences which are part of context triggers. These context triggers can initiate a communication event upon a particular context update. Additionally, in order to provide the described context-aware communication functions, these mechanisms need timely access to the acquired (desired) context information. This in turn raises a plethora of other questions, such as how to discover sensors that provide the desired context information; how to acquire raw context data from these sensors; how to abstract, process, and model this data to become "understandable" to applications and system components; and how to distribute this context to applications that are running on different nodes.</p><p> </p><p>This research is split into three different parts. The first part concerns investigating and implementing context management functions. As part of this research we propose a novel approach for context synthesis using context operators. We also propose a design architecture for context-aware middleware that mediates between the sensors and applications, and that is able to share and retrieve context from other nodes in the network. The second part of our research concerns our proposed mechanism for context-addressed messaging. To implement this mechanism we designed our own message format, called the Common Profile for Context-Addressed Messaging (CPCAM) that is able to use any high level context to compose a context-based address. Additionally, we proposed to use context-based filtering to find the correct message recipients and determine if this message is relevant to these potential message recipients in their current context, as well as to deliver this message to the recipients' preferred device that is adapted using their preferred communication means. At the end of this second part we design context-addressed messaging system operations on top of a SIP and SIMPLE-based network infrastructure. The third part of our research describes context-aware session control mechanisms using context switch and context trigger constructs. A context-switch selects an action from a set of context-dependent actions upon an incoming communication event based on the receiver's current context. In contrast, a context trigger initiates an action based on a context update and the user's preferences that are specified in this updated context. This part illustrates in several examples the context-aware session control mechanisms, i.e. the initiation of a communication session based on the match of a user's preferences and current context, as well as adaptation and (if necessary) termination of an ongoing communication session based upon the user's context-dependent preferences.</p><p> </p><p>The research leading to this licentiate has created network and system level models necessary for implementation of a context-addressed communication system that would enable users to easily design their own personalized, context-aware communication services. The necessary constructs and properties of these models are designed and analyzed in the thesis, as well as in conference papers and other documents published in the process of doing the research for this thesis. A number of remaining open issues and challenges have been outlined as part of the future work.</p><p> </p> / EU FP6 MIDAS (Middleware Platform for Developing and Deploying Advanced Mobile Services) / EU FP6 MUSIC (Self-adapting Applications for Mobile Users In Ubiquitous Computing Environments)

Introdução: Um dos objetivos mundiais para a melhoria da qualidade de vida da população é a redução da mortalidade materna. Visto que esta expressa não só contextos relacionados à saúde, mas também, epidemiológico, social e econômico. Uma maneira de promover mudança nas taxas de mortalidade materna é por meio do enfrentamento de barreiras para a melhoria do cuidado obstétrico. Países que já superaram a falta de serviços e de acesso à assistência obstétrica enfrentam problemas relacionados à qualidade da atenção ao parto e nascimento. Como por exemplo, danos a saúde materna e neonatal decorrentes de intervenções desnecessárias ou até desaconselhadas. A utilização da tecnologia móvel por meio de mensagens enviadas às gestantes tem se mostrado eficaz, com melhorias no cuidado durante o pré-natal e pós-parto. Esta dissertação foi desenvolvida por acreditar que o uso de mensagens enviadas às gestantes no pré-natal poderia modificar fatores relacionados à assistência ao parto. Objetivo: Avaliar se mensagens enviadas por celular às gestantes produz efeito sobre a satisfação das mulheres com o atendimento ao parto, sobre o uso de boas práticas no parto e sobre a percepção delas sobre a ocorrência de abuso, desrespeito e/ou maus-tratos durante o parto. Métodos: Esta é uma análise secundária de um ensaio aleatorizado por conglomerados em 20 unidades básicas de saúde (UBS) com maior número de seguimento pré-natal. As 20 UBS foram aleatorizadas (1:1) de forma balanceada, por meio de um software, formando um grupo Intervenção e um Controle, com dez UBS cada. Do grupo Intervenção origina o grupo que efetivamente recebeu a intervenção (grupo PRENACEL). A intervenção compreendeu o oferecimento de um pacote de mensagens enviadas para o celular das gestantes como um complemento ao pré-natal padrão da rede pública. Participaram do estudo mulheres com 18 anos ou mais, com até 20 semanas de gestação, que estavam em seguimento pré-natal nas UBS selecionadas. A coleta de dados foi realizada em quatro maternidades, e para o presente estudo, foram avaliadas mulheres que tiveram partos por via vaginal e sem gestações de alto risco. Os desfechos avaliados foram: a satisfação dasmulheres com o atendimento ao parto; o uso de boas práticas na assistência ao parto e a percepção das mulheres sobre a ocorrência de abuso, desrespeito e/ou maus-tratos. Resultados: Esta pesquisa foi composta por 241 mulheres no grupo Controle e 427 no grupo Intervenção, sendo 63 pertencentes ao grupo PRENACEL. Não houve diferença estatística entre os grupos em relação à satisfação ou uso de boas práticas. Nem sobre a percepção das mulheres sobre a ocorrência de abuso, desrespeito e/ou maus-tratos durante o parto. Encontramos alta satisfação das mulheres com o atendimento e alta frequência de uso de boas práticas durante o parto comparado ao cenário nacional. Já a percepção delas sobre ocorrência de abuso, desrespeito e/ou maus-tratos foi baixa. Conclusão: O uso de mensagens enviadas a gestantes no pré-natal não demonstrou efeito sobre os desfechos avaliados. / Introduction: One of the world\'s goals for improving the population\'s quality of life is to reduce maternal mortality. This is because it expresses not only contexts related to health, but also epidemiological, social and economic. A way to promote change in maternal mortality rates it is by facing barriers to improve obstetric care. Countries that have overcome the lack of services and access to obstetric care face problems related to the quality of childbirth care. As for example, damage to maternal and neonatal health still occurs from unnecessary or non-advisable interventions. The use of mobile technology through messages sent to pregnant women has been shown to be effective, with improvements in antenatal and postpartum care. Objective: To evaluate whether messages sent by cell phones to pregnant women have an effect on women\'s satisfaction with delivery, on the use of good practices during childbirth and on their perception of abuse, disrespect and / or mistreatment during the delivery. Methods: This is a secondary analysis of a cluster-randomized trial in 20 Primary Health Care Units (PHCU) with a higher number of prenatal followup. The 20 PHCU were randomized (1:1) in a balanced manner, using software, forming an Intervention and a Control group, with ten UBS each. From the Intervention group, the group that actually received the intervention (PRENACEL group). The intervention included the provision of a package of messages sent to the pregnant women\'s cell phone as a complement to the prenatal standard of the public network. Participants were women 18 years of age or older, up to 20 weeks of gestation, who were undergoing prenatal follow-up at selected PHCU. Data were collected in four maternity hospitals, and for the present study, women who had deliveries vaginally and without high-risk pregnancies were evaluated. The outcomes evaluated were: the satisfaction of women with delivery; the use of good practices in childbirth care and women\'s perception of abuse, disrespect and / or mistreatment. Results: This study was composed of 241 women in the Control group and 427 in the Intervention group, of which 63 belonged to the PRENACEL group. There was no statistical difference between groups regarding satisfaction or use of good practices. Neither about the perception of women about the occurrence of abuse, disrespectand / or mistreatment during childbirth. We found high satisfaction of women with the attendance and high frequency of use of good practices during childbirth compared to the national scenario. Their perception of abuse, disrespect and / or mistreatment was low. Conclusion: The use of messages sent to pregnant women during prenatal care did not show any effect on the outcomes evaluated.
