Providing the user with good user experience is complex and involves multiple factors. One of the factors that can impact the user experience is animation. Animation can be tricky to get right and needs to be understood by designers. Animations that are too fast might not accomplish anything and having them too slow could slow the user down causing them to get frustrated.

This study explores the subject of animation and its speed by trying to answer the following questions – 1) Do people notice whether an animation is present 2) Does animation affect the enjoyment of a transition? and 3) If animation does affect enjoyment, what is the effect of different animation speeds?

The study was conducted using 3 prototypes of an application to order bottled water in which the transitions between different brands of bottled water were animated at 0ms, 300ms and 650ms. A survey was conducted to see if the participants were able to spot any difference between the prototypes and if they did, which one they preferred.

It was found that most people did not recognize any difference between the prototypes. Even people who recognized a difference between the prototypes did not have any preference of speed.

Data from a total of 282 online web applications was collected, and accounts for 230 of those web applications were created in order to gather data about authentication practices, multistep authentication practices, security question practices, fallback authentication practices, and other security practices for online accounts. The account creation and data collection was done between June 2016 and April 2017. The password strengths for online accounts were analyzed and password strength data was compared to existing data. Security questions used by online accounts were evaluated for security and usability, and fallback authentication practices were assessed based on their adherence to best practices. Alternative authentication schemes were examined, and other security considerations such as use of HTTPS and CAPTCHAs were explored. Based on existing data, password policies require stronger passwords in for web applications in 2017 compared to the requirements in 2010. Nevertheless, password policies for many accounts are still not adequate. About a quarter of online web applications examined use security questions, and many of the questions have usability and security concerns. Security mechanisms such as HTTPS and continuous authentication are in general not used in conjunction with security questions for most web applications, which reduces the overall security of the web application. A majority of web applications use email addresses as the login credential and the password recovery credential and do not follow best practices. About a quarter of accounts use multistep authentication and a quarter of accounts employ continuous authentication, yet most accounts fail to combine security measures for defense in depth. The overall conclusion is that some online web applications are using secure practices; however, a majority of online web applications fail to properly implement and utilize secure practices.

A study to determine the preliminary effects of a theory-based intervention: (SayNo2Flu) combined with the use of mobile technology on parents' influenza prevention beliefs and behaviors in a primary care setting

Description

This study tested the preliminary effectiveness of a health belief and text messaging intervention for parents of five- to eight-year-old children to determine whether health beliefs and influenza vaccine receipt

This study tested the preliminary effectiveness of a health belief and text messaging intervention for parents of five- to eight-year-old children to determine whether health beliefs and influenza vaccine receipt differ when compared to a text messaging control group. Children are almost four times more likely to be infected with influenza than adults (Belshe Piedra, & Block, 2009), shed the greatest quantities of influenza virus, and have been recognized as vectors for spread of disease (Neuzil, Mellen, Wright, Mitchel, Jr., & Griffin, 2002b). The influenza immunization rate for school-age children is less than 56% (Centers for Disease Control and Prevention [CDC], 2014). Reasons for the low vaccination rate include parents’ misperceptions of influenza disease and vaccinations (Bhat-Schelbert et al., 2012; Taylor et al., 2002). There are few theory-based interventions for increasing influenza vaccination rates of school-age children; however, promising results have been found when using the constructs of the health belief model (HBM) (Chen et al., 2011; Coe, Gatewood, Moczygemba, Goode, & Beckner, 2012). Mobile technology using Short Message Service (SMS) text messaging may increase vaccination rates to a greater extent than traditional vaccine reminders (Daley et al., 2002; Grajalva, 2006). Prior to starting this study, only one randomized controlled trial testing text messaging to increase children’s influenza vaccination rates was found (Stockwell et al., 2012). In this study, text messaging was effective in promoting behavioral changes leading to a 4% increase in influenza vaccination (27.1% vs. 22.8%, RR = 1.19, p < .001). This study was a randomized controlled trial using a two-group pre- and posttest experimental design. This study found that a theory-based intervention (SayNo2Flu) guided by the HBM and combined with the use of mobile technology (SMS text messaging) did change parents’ influenza vaccination perceptions. It had an overall increase of 38.1% in Influenza vaccination rates in the intervention group (OR: 4.46, 95% CL, 1.705-11.706, p < .001). These results offer some insight into the use of theory-based preventative interventions for parents of young school-age children.

Digitextos: blooks, blogs, y poesía digital : la literatura de escritoras hispanas en internet : Almudena Montero, María Amelia López Soliño, Yoani Sánchez y Belén Gache

Description

En el siglo XXI nuestra vida se está cruzando constantemente con la tecnología, tanto que algunos declaran que nuestro mundo se ha hecho posthumano, ya que no se puede separar

En el siglo XXI nuestra vida se está cruzando constantemente con la tecnología, tanto que algunos declaran que nuestro mundo se ha hecho posthumano, ya que no se puede separar al ser humano de la máquina. Aunque algunos se sientan amenazados por estas tecnologías, otros están abrazando la Red Mundial, aprovechándose de las infinitas oportunidades que ofrece. Uno de estos elementos fundamentales que internet posibilita es la capacidad de comunicarse directamente con otras personas. El blog por ejemplo, o bitácora en español, permite que los usuarios se proyecten a sí mismos o a sus pseudo-identidades, sus pensamientos e ideas a través del texto que escriben en internet. También sus lectores pueden responder a estos autores inmediatamente. Los posts publicados--entradas en una página web--, aunque aparecen cronológicamente, son episodios fragmentados. Pero el blog no se limita a la producción de un texto sino que el autor puede también "jugar" con el cuerpo del texto para añadir hipervínculos y multimedia. Esta forma de escribir está cambiando lo que se considera "válido" como texto, incluso lo que se considera literatura. El objetivo de este trabajo no es estudiar la literatura digital en su totalidad, sino específicamente en algunas obras escritas por mujeres en internet. Si se considera la escritura digital como una forma de arte marginalizada, se podría decir que la escritura realizada por mujeres en internet experimenta una doble-marginalidad debido al hecho de que la literatura de mujeres siempre ha sido marginal al canon. Este estudio tomará un punto de vista transatlántico, incluyendo en el mismo a varias escritoras hispanohablantes de diferentes edades, experiencias y con variados motivos en su trabajo que publican sus obras en internet. Estas autoras incluyen las blogueras Almudena Montero (española) yMaría Amelia López Soliño (española); la periodista ciudadana Yoanis Sánchez (cubana); y la poeta digital/crítica Belén Gache (española-argentina). En esta tesis he explorado y considerado la noción de que el internet sirve como un medio de democratización puesto que, hasta cierto punto, las fronteras de género y nacionalidad desaparecen. Por esta razón, este trabajo va a considerar varias teorías tales como el postmodernismo, las teorías sobre la escritura de mujeres y teorías sobre la democratización de la tecnología para analizar la literatura que se encuentra en la red. Aunque las escritoras analizadas en este proyecto son distintas, y usan la tecnología de maneras diferentes, tienen una misma meta: expresarse libremente y comunicarse directamente con sus lectores al conectarse a internet. Mi hipótesis de trabajo consiste en que estas mujeres escriben de una manera particular--es decir, que no escriben igual a los hombres que escriben en internet--y que la red ofrece una plataforma única a las mujeres: en este espacio ellas son más activas--en oposición a la literatura tradicional-- en cuanto a compartir y publicar su propio trabajo e ideas.

Analysis and decision-making with social media

Description

The rapid advancements of technology have greatly extended the ubiquitous nature of smartphones acting as a gateway to numerous social media applications. This brings an immense convenience to the users

The rapid advancements of technology have greatly extended the ubiquitous nature of smartphones acting as a gateway to numerous social media applications. This brings an immense convenience to the users of these applications wishing to stay connected to other individuals through sharing their statuses, posting their opinions, experiences, suggestions, etc on online social networks (OSNs). Exploring and analyzing this data has a great potential to enable deep and fine-grained insights into the behavior, emotions, and language of individuals in a society. This proposed dissertation focuses on utilizing these online social footprints to research two main threads – 1) Analysis: to study the behavior of individuals online (content analysis) and 2) Synthesis: to build models that influence the behavior of individuals offline (incomplete action models for decision-making).

A large percentage of posts shared online are in an unrestricted natural language format that is meant for human consumption. One of the demanding problems in this context is to leverage and develop approaches to automatically extract important insights from this incessant massive data pool. Efforts in this direction emphasize mining or extracting the wealth of latent information in the data from multiple OSNs independently. The first thread of this dissertation focuses on analytics to investigate the differentiated content-sharing behavior of individuals. The second thread of this dissertation attempts to build decision-making systems using social media data.

The results of the proposed dissertation emphasize the importance of considering multiple data types while interpreting the content shared on OSNs. They highlight the unique ways in which the data and the extracted patterns from text-based platforms or visual-based platforms complement and contrast in terms of their content. The proposed research demonstrated that, in many ways, the results obtained by focusing on either only text or only visual elements of content shared online could lead to biased insights. On the other hand, it also shows the power of a sequential set of patterns that have some sort of precedence relationships and collaboration between humans and automated planners.

Bad Faith Rhetorics in Online Discourses of Race, Gender, Class, and Sexuality

This dissertation theorizes Bad Faith Rhetorics, or, rhetorical gestures that work to derail, block, or otherwise stymy knowledge-building efforts. This work explores the ways that interventions against existing social hierarchies (i.e., feminist and antiracist interventions) build knowledge (that is, are epistemologically active), and the ways that bad faith rhetorics derail such interventions. This dissertation demonstrates how bad faith rhetorics function to defend the status quo, with its social stratification by race, gender, class, and other intersectional axes of identity. Bad faith argumentative maneuvers are abundant in online environments. Consequently, this dissertation offers two case studies of the comment sections of two TED Talks: Mellody Hobson’s “Color Blind or Color Brave?” and Juno Mac’s “The Laws that Sex Workers Really Want.” The central analyses deploy online ethnographic field methods and close reading to characterize bad faith rhetorical responses and to identify 1.) trends in such responses, 2.) the net effects on other conversational participants, and 3.) bad faith rhetoric mitigation strategies. This work engages Sartre’s work on Bad Faith, rhetoric scholarship on the knowledge-building affordances of argument, public sphere theory, critical race studies, and feminist scholarship. This dissertation’s theorization and case studies illustrate the pitfalls of specific counterproductive argumentative tactics that block progress toward more equitable ways of being (bad faith rhetorics), and makes several preliminary recommendations for mitigating such moves.

Individuals, collectives, sisters: vernacular cosmopolitan praxis among Muslim women in transnational cyberspaces

This dissertation research analyzes the vernacular cosmopolitan praxis of Muslim women in transnational cyberspaces related to topical and collective action networks, in an effort to detangle cosmopolitanism from its Western biases and to move away from studies of online Muslim populations based on geographical locations or homogenous networks, linking individuals through their religious practices or consumption of religious knowledge. Through highlighting praxes rather than contexts, this dissertation disrupts the East/West binary and challenges stereotypes ascribed to Muslim women. One of the research questions related to the cosmopolitan praxis of Muslim women is the following: in what ways do Muslim women engage with "others" online and contribute to bridging dissimilar people? Findings suggest that the social media use of Muslim women contributes to their subtle resistance against communal norms and, although it can serve as an extension to their voices, some of their voices are more readily mediated than others. I employ a connective content analysis methodology to put various datasets associated with topics and collective actions related to Muslim women into conversation. The methodology not only highlights consistencies in the qualitative themes that were iteratively developed through the analyses of the datasets, but also more tangible connections related to social media users, topics, and content. Consequently, this thesis is as much concerned with recasting Western-oriented conceptualizations of cosmopolitanism as it is with how networks dynamics foster and constrain cosmopolitan praxis because digital networks have the extraordinary capacity to link dissimilar people beyond any other type of medium. One of the research questions related to the methodology is: how do network dynamics facilitate and constrain cosmopolitan praxis? The substantive chapters related to the datasets discuss various forms of cosmopolitan praxis that were identified in the analysis: social media use by Muslim women that expands the connective memory, which could contribute to dispelling stereotypes ascribed to them; activism that addresses universal concerns related to women's rights regardless of context; dialogically devising basic standards of social conduct and gender relations; and expressions of tolerance toward divergent views, including alternative interpretations of Islamic beliefs and practices.

The Jon Finn Group, a four-piece instrumental rock band based in Boston, MA, was in need of a website redesign, http://JonFinn.com. They required a website to showcase and sell their music and merchandise, promote upcoming performances, interact directly with their fans, integrate with social networking websites, and administer paid membership subscriptions via a content management system. Making this possible required an overhaul of the website, which was based almost entirely on static HTML files with limited capabilities for dynamic content updates. The band also requested a complete visual design overhaul compatible with traditional desktop computer web browsers, cell phone-based web browsers, and modern touch-based web browsing interfaces. WordPress, a free open-source content management system, was chosen to implement technologies to meet the Jon Finn Group's needs. Using WordPress required the development of a custom visual theme supported by various free and commercial plugins. WordPress and the supporting plugins required customization to extend functionality for becoming a revenue-generating platform through which paid membership subscriptions could be supported and administered. A survey instrument questioning end users on usability was used to measure the success of the website redesign and WordPress implementation. To evaluate the success of the redesign, analysis was performed on empirical data collected from web analytics and responses from the usability survey instrument as well as subjective data including stakeholder feedback and comments provided by the usability survey instrument respondents. Following the completion of the site redesign, it became clear that the site better engaged users than the previous site iteration and met end-users' usability expectations. Web analytics data indicated that users began spending more time on JonFinn.com and viewing more content than they had on the former website design. Usability survey data indicated that 95% of all tested functionality was found to be either "not difficult at all" or only "slightly difficult." Some comments and response data clearly indicated areas for improvement in the design and usability of the site.

Open innovation implementation in a public university: administrator design, management, and evaluation of participatory platforms and programs

Public organizations have been interested in tapping into the creativity and passion of the public through the use of open innovation, which emphasizes bottom-up ideation and collaboration. A challenge for organizational adoption of open innovation is that the quick-start, bottom-up, iterative nature of open innovation does not integrate easily into the hierarchical, stability-oriented structure of most organizations. In order to realize the potential of open innovation, organizations must be willing to change the way they operate. This dissertation is a case study of how Arizona State University (ASU), has adapted its organizational structure and created unique programming to incorporate open innovation. ASU has made innovation, inclusion, access, and real world impact organizational priorities in its mission to be the New American University. The primarily focus of the case study is the experiential knowledge of administrative leaders and administrative intermediaries who have managed open innovation programming at the university over the past five years. Using theoretical pattern matching, administrator insights on open innovation adoption are illustrated in terms of design stages, teamwork, and ASU's culture of innovation. It is found that administrators view iterative experimentation with goals of impact as organizational priorities. Institutional support for iterative, experimental programming, along with the assumption that not every effort will be successful, empowers administrators to push to be bolder in their implementation of open innovation. Theoretical pattern matching also enabled a detailed study of administrator alignment regarding one particular open innovation program, the hybrid participatory platform 10,000 Solutions. Creating a successful and meaningful hybrid platform is much more complex than administrators anticipated at the outset. This chapter provides administrator insights in the design, management, and evaluation of participatory platforms. Next, demographic assessment of student participation in open innovation programming is presented. Demographics are found to be reflective of the university population and provide indicators for how to improve existing programming. This dissertation expands understanding of the task facing administrators in an organization seeking to integrate open innovation into their work.
