A malware threat avoidance model for online social network usersIkhalia, Ehinome January 2017 (has links)
The main purpose of this thesis is to develop a malware threat avoidance model for users of online social networks (OSNs). To understand the research domain, a comprehensive and systematic literature review was conducted and then the research scope was established. Two design science iterations were carried out to achieve the research aim reported in this thesis. In the first iteration, the research extended the Technology Threat Avoidance Theory (TTAT) to include a unique characteristic of OSN - Mass Interpersonal Persuasion (MIP). The extended model (TTAT-MIP), focused on investigating the factors that needs to be considered in a security awareness system to motivate OSN users to avoid malware threats. Using a quantitative approach, the results of the first iteration suggests perceived severity, perceived threat, safeguard effectiveness, safeguard cost, self-efficacy and mass interpersonal persuasion should be included in a security awareness system to motivate OSN users to avoid malware threats. The second iteration was conducted to further validate TTAT-MIP through a Facebook video animation security awareness system (referred in this thesis as Social Network Criminal (SNC)). SNC is a Web-based application integrated within Facebook to provide security awareness to OSN users. To evaluate TTAT-MIP through SNC, three research techniques were adopted: lab experiments, usability study and semi-structured interviews. The results suggest that participants perceived SNC as a useful tool for malware threat avoidance. In addition, SNC had a significant effect on the malware threat avoidance capabilities of the study participants. Moreover, the thematic analysis of the semi-structured interviews demonstrated that the study participants' found SNC to be highly informative; persuasive; interpersonally persuasive; easy to use; relatable; fun to use; engaging; and easy to understand. These findings were strongly related to the constructs of TTAT-MIP. The research contributes to theory by demonstrating a novel approach to design and deploy security awareness systems in a social context. This was achieved by including users' behavioural characteristic on the online platform where malware threats occur within a security awareness system. Besides, this research shows how practitioners keen on developing systems to improve security behaviours could adopt the TTAT-MIP model for other related contexts.

Emergent social network communities : hashtags, knowledge building, and communities of practiceFord, Kasey Crystal 15 November 2013 (has links)
The hashtag #phdchat is used by doctoral students all over the world to engage with their peers, share information, and commiserate over their experiences in academia. Anyone can join the conversation simply by typing the tag and publishing a tweet, but many regularly contribute to what has become a vibrant emergent social network community. Using an analysis of the discourse that was labeled with the hashtag over about a one-month period, this paper draws conclusions about who belongs to this community and what the network achieves for the users and as an entity of its own. The researcher makes conclusions about this network by drawing on the attributes of communities of practice and knowledge building communities in order to ground it as its own permutation of a learning community. / text

INFLUENCE OF THE GOVERNANCE SYSTEM ON DEFINING THE URBAN VEGETATION PATTERNS IN A LATIN AMERICAN METROPOLIS. THE CASE OF SANTIAGO DE CHILE / EINFLUSS DES STEUERUNGSSYSTEMS AUF DIE URBANE VEGETATION. DER FALL SANTIAGO DE CHILEREYES-PÄCKE, SONIA 28 January 2015 (has links) (PDF)
Spatial and temporal patterns of urban vegetation have been widely studied since the mid-twentieth century, but these studies have focused mainly on northern hemisphere countries, and little research has been conducted in developing countries.
Urban vegetation is characterized by the presence of species that are adapted to the particular environmental conditions of cities, and a high diversity of exotic species. This occurs due to a combination of factors: on one hand, it is possible to find wild vegetation (weeds) on abandoned lands or those with little intervention, as well as on walls and buildings. On the other hand, there is also an enormous variety of ornamental and mainly exotic species, which have been cultivated by humans.
The processes of species selection performed individually or collectively are a major determinant of the diversity of urban vegetation and flora. Individual decisions relate to private spaces such as residential gardens whose owners manage the vegetation according to their preferences and interests. Collective decisions relate to public spaces, which, by their nature, are subject to the action of multiple stakeholders. At the collective level, decision-making occurs in the context of processes involving local governments, other state agencies, NGOs and various interest groups present in the city. Each of these actors has its own vision on the role of urban vegetation, their preferences and criteria for the selection and management.
This study aims to investigate the processes of decision-making responsible for the current composition of the vegetation in public spaces of the Metropolitan Area of Santiago (MAS). Through this research is expected to identify the criteria for the selection of species to be planted in public spaces, the reasons that explain the predominance of certain species, and the difference between parks managed by different public agencies in MAS. The research assumes that the various public and private actors involved in the planting and management of vegetation in public spaces, act guided by criteria and preferences that are finally expressed in the observed patterns of urban vegetation.
For this purpose, the conceptual framework of governance is used, understood as the process of decision-making concerning public affairs, which involves multiple agents or interests including government agencies, non-governmental organizations and civil society groups.
The overarching objectives of this Thesis are:
a) To contribute to the knowledge of interactions between governance system and urban vegetation patterns in metropolitan areas of developing countries, recognizing both social and environmental processes interacting.
b) Contribute to urban planning and policies by generating knowledge relevant to decision- making regarding urban vegetation.
A robust knowledge of the factors defining the composition and structure of urban vegetation is essential to design effective policies for increasing vegetation cover, with consequent environmental and social benefits.

Circulação e recirculação de narrativas do acontecimento no jornalismo em rede : a Copa do Mundo de 2014 no twitterZago, Gabriela da Silva January 2014 (has links)
A presente tese tem por objetivo identificar estruturas e dinâmicas associadas à circulação de diferentes tipos de acontecimentos jornalísticos no Twitter. Busca-se, com isso, comparar as formas de circulação de narrativas em torno de diferentes tipos de acontecimentos jornalísticos em sites de rede social. Tem-se como pressuposto o fato de que o jornalismo contemporâneo estaria configurado como uma rede, formada por nós compostos por diversos atores para além dos veículos jornalísticos, os quais, através da participação de variadas formas, contribuem para a circulação jornalística. O referencial teórico do trabalho aborda o paradigma de redes, a circulação na cibercultura e no jornalismo, as especificidades da circulação e da recirculação jornalística em sites de rede social e o acontecimento jornalístico. Para operacionalizar a pesquisa, utiliza-se como método o estudo de caso de postagens no Twitter em torno de determinados acontecimentos jornalísticos associados à Copa do Mundo de 2014. Ao todo quatro casos são estudados tendo como procedimentos metodológicos a observação e a análise de redes sociais. Os resultados trazem indícios de que a participação do público na circulação jornalística traz modificações não apenas para o jornalismo como também pode provocar ressignificações no próprio acontecimento. / In this thesis, we aim to identify structures and dynamics associated to the circulation of different types of news events on Twitter. Thus, we seek to compare forms of circulation of narratives about different types of news events in social network sites. One of the premises we adopt is the fact that contemporary journalism is shaped like a network, composed by nodes that comprises diverse actors beyond news outlets, which, through participation in various forms, contribute to news circulation. We use as a theoretical background concepts related to the network paradigm, to circulation of contents on cyberculture and journalism, the specificities of news circulation and recirculation in social network sites, and news events. In order to operationalize the research, we use the method of case study of posts on Twitter about some specific news events related to the 2014 FIFA’s World Cup. We studied four cases using a combination of observation and social network analysis. The results provide evidence that the participation of the public on news circulation brings changes not only for journalism but also leads to a reframing in the events themselves.

Student Interactions in Edmodo Versus FacebookJanuary 2013 (has links)
abstract: ABSTRACT This study describes student interactions in the academic social network site Edmodo versus student interactions in Facebook. This qualitative case study relies upon four high school juniors enrolled in Advanced Placement Language and Composition who use Edmodo to complete assignments for their English class. Their experiences were gathered in an attempt to describe specific experiences in a complex system. Students were selected using an Internet Connectedness Index survey. Using a Virtual Community of Practice framework, students were asked about their experiences in Edmodo. This study concludes that Edmodo and Facebook can be compared in three categories: accessibility, functionality, and environment. Unlike Facebook, which students access regularly, students access Edmodo only to fulfill the teacher's participation expectations for the specific grade they wish to receive. Additionally, students appreciated the convenience of using Edmodo to complete assignments. The functionality of Edmodo is quite similar in layout and appearance to Facebook, yet students were unaware of the media sharing capability, wished for private messaging options, and desired the ability to tag peers for direct comment using the @ sign, all options that are available in Facebook. Students felt the environment in Edmodo could best be characterized as intellectual and academic, which some mentioned might best be used with honors or AP students. A surprising benefit of Edmodo is the lack of social cues enable students to feel free of judgment when composing writing. Some felt this allowed students to know their classmates better and share their true personae free from judgment of classmates. As a result of the case studies of four students, this study seeks to illustrate how students interact in Edmodo versus Facebook to provide a robust image of the academic social network site for teachers seeking to implement educational technology in their classes. / Dissertation/Thesis / Ed.D.
