Description
Online editors using Saudi Arabian social media platforms are in a novel position,providing news in an environment where they themselves are not trained journalists, on publication platforms that developed independently of legacy news organizations, and in a cultural context where journalism is constrained by government and societal concerns. Yet, they provide a highly popular and growing venue for news distribution. As such, the news values they consciously consider and profess they choose when selecting and posting their news content online is of substantive interest in terms of local and global practice. The potential ramifications of their choices include the framing and documentation of past, present and future events and perspectives. Therefore, this research seeks to determine and understand the news values that online editors on Saudi Arabian social media platforms consciously consider and believe they choose when selecting and posting their news content online. It also explores whether those online editors consider audience news preferences when they select what they report or republish.
This dissertation relied on qualitative in-depth interviews with nine online editors who worked for the top news accounts on social media in Saudi Arabia. Analysis of interview responses showed that impact, timeliness, proximity, novelty, positivity, and nationalism were the common news values the online editors held. The analysis, which concluded that the online editors used the different engagement tools available in social media to enhance their understanding of the audience and their news preference, suggests further interpretation regarding a market orientation. The interactivity played important roles in making profits for the news accounts, facilitating and mapping the news accounts’ work, and measuring the online editors’ personal success and progress. Finally, although the online editors said they prioritized and assured the importance of selecting news based on audience news preference, they professed an awareness of their role as journalists in the society. In the interviews, they give insight into how they select some content based on their own preferences and their understanding about what the audience should know. This suggests an evolving journalistic environment in Saudi Arabia on the fastest-growing information-sharing publication platform. KEYWORDS: Journalism, social media, engagement, interactivity, online editors, audience, news values, news selection, audience news preferences, in-depth interviews, Saudi Arabia.

Description
Delamination of solar module interfaces often occurs in field-tested solar modules after decades of service due to environmental stressors such as humidity. In the presence of water, the interfaces between the encapsulant and the cell, glass, and backsheet all experience losses of adhesion, exposing the module to accelerated degradation. Understanding the relation between interfacial adhesion and water content inside photovoltaic modules can help mitigate detrimental power losses. Water content measurements via water reflectometry detection combined with 180° peel tests were used to study adhesion of module materials exposed to damp heat and dry heat conditions. The effect of temperature, cumulative water dose, and water content on interfacial adhesion between ethylene vinyl acetate and (1) glass, (2) front of the cell, and (3) backsheet was studied. Temperature and time decreased adhesion at all these interfaces. Water content in the sample during the measurement showed significant decreases in adhesion for the Backsheet/Ethylene vinyl acetate interface. Water dose showed little effect for the Glass/ Ethylene vinyl acetate and Backsheet/ Ethylene vinyl acetate interfaces, but there was significant adhesion loss with water dose at the front cell busbar/encapsulant interface. Initial tensile test results to monitor the effects of the mechanical properties ethylene vinyl acetate and backsheet showed water content increasing the strength of ethylene vinyl acetate during plastic deformation but no change in the strength of the backsheet properties. This mechanical property change is likely inducing variation along the peel interface to possibly convolute the adhesion measurements conducted or to explain the variation seen for the water saturated and dried peel test sample types.
