Asymptotic normality for weighted sums of linear processes

We establish asymptotic normality of weighted sums of linear processes with general triangular array weights and when the innovations in the linear process are martingale differences. The results are obtained under minimal conditions on the weights and innovations. We also obtain weak convergence of weighted partial sum processes. The results are applicable to linear processes that have short or long memory or exhibit seasonal long memory behavior. In particular, they are applicable to GARCH and ARCH(∞) models and to their squares. They are also useful in deriving asymptotic normality of kernel-type estimators of a nonparametric regression function with short or long memory moving average errors

Perceptions of Wikipedia by Public Relations Professionals: A Comparison of 2012 and 2013 Surveys

Wikipedia has arguably become a staple in society. In fact, of all the information sources available on the Internet, Wikipedia is one of the most widely used. The problem that public relations professionals face is what Wikipedia co-founder Jimmy Wales calls a “bright line’ rule.” This rule requires public relations professionals to use the Talk pages to request changes to the Wikipedia articles for their company or client instead of directly editing the content. To examine the effectiveness of this rule and explore current Wikipedia experiences, this study reports the results of a survey conducted in 2013. Comparisons to a similar 2012 study are also noted

Industry in Crisis: The Communication Challenge in the Banking Industry

As the number of high-profile failures and mergers of many large financial companies continues to grow, so does distrust in the industry. This study explores how communication professionals at financial companies are handling the global financial crisis. Although participants believed that communication must be accurate, timely, and transparent, they are greatly challenged by the quantity of communication needed. Many of the participants in this study had unique ways of handling certain aspects of communication needs. Ultimately, the collective of communication professionals at individual financial instructions can lead to the rebuilding of trust and confidence in financial organizations, and this study provides a glimpse into how they are accomplishing this massive feat

How Millennials are Engaging and Building Relationships with Organizations on Facebook

More than half of Facebook’s 900 million active users in the U.S. consist of the Millennial generation (ages 13 to 29). With more organizations taking advantage of the site’s reach, determining how organizations are interacting with Millennials on Facebook is important.  This study used qualitative focus groups and a quantitative survey to examine how Millennials preferred to interact and engage with organizations on Facebook. Results found participants were not opposed to interacting with organizations on Facebook, but were very specific in terms of how, with who, and why they wanted to engage. While Millennials did want updates and other information depending on the type of organization or group, they also wanted discounts or other benefits. Millennials identified reasons why they would actively terminate the relationship with an organization

A Benchmark Analysis of the Strategic Use of Social Media for Fortune’s Most Admired U.S. Companies on Facebook, Twitter and YouTube

By exploring the strategic use of social media for 250 of Fortune’s Most Admired U.S. Companies on Facebook, Twitter, and YouTube, this study creates a benchmark by which companies can use to gauge their involvement in the three dominant social media platforms. Results found that 91% of the companies utilized at least one social media platform. YouTube was the most commonly adopted social media followed by Twitter then Facebook. Overall, 30% of companies in this study provided a social media code of conduct in at least one platform, 58% integrated their social media accounts, 14% used a human voice, and 52% used a dialogic loop. Each of the topics is explored for each of the three social media platforms and suggestions for companies are included

Forced Transparency: Corporate Image on Wikipedia and What it Means for Public Relations

Collaboratively edited information on social media that circumvents traditional media gatekeepers poses a challenge to public relations practitioners. The online encyclopedia Wikipedia gives corporate critics the opportunity to shape the public image of major corporations. This longitudinal panel study analyzed the framing of 10 Fortune 500 companies on Wikipedia between 2006 and 2010. It was found through content analyses of tonality and topics of more than 3,800 sentences in the articles for Wal-Mart, Exxon Mobil, General Motors, Ford, General Electric, Chevron, ConocoPhillips, Citigroup, AIG, and IBM that the negativity increased over time and that the focus shifted from historical information to legal concerns and scandals. The findings show that public relations practitioners need to pay close attention to the forced transparency about their companies on Wikipedia

Use of social networks as a CSR communication tool

The aim of this paper is to analyse the use of online social networks as a tool for Corporate Social Responsibility (CSR) communication and management. To this end, an analysis was performed of the messages posted by the 20 Spanish companies with the highest market capitalisation and the responses that they received on two of the most popular online social networks, Facebook and Twitter. The results of the analysis of these data show that the tendency has been to use social networks for the one-way communication of aspects of CSR related with the organisation. Therefore, it is necessary to change the way companies communicate their CSR issues by shifting to a two-way communication approach, as has been the case in other kinds of enterprise relations with their stakeholders.The authors received no direct funding for this research
