The Competitive Impact of Targeted Television Advertisements Using DVR Technology

Digital video recorders (DVRs) are an emerging technology that is fundamentally changing the competitive landscape in industries that advertise on television. Perhaps the most familiar impact of DVR technology is that it enables consumers to avoid advertisements (ads) by fast forwarding through them. However, this “zipping” of ads is only one aspect of the impact of DVR technology. DVRs also collect a wealth of information at the consumer level that can be used by firms to target their ads more effectively. We examine how this targeting capability moderates the impact of ad avoidance in a competitive setting. Insights are provided on how best to manage this emerging technology in terms of the key managerial decisions of product pricing and advertising efforts, as well as its impact on profits in a competitive (duopoly) marketplace.     

Estimating and comparing adverse event probabilities in the presence of varying follow-up times and competing events

Safety analyses of adverse events (AEs) are important in assessing benefit–risk of therapies but are often rather simplistic compared to efficacy analyses. AE probabilities are typically estimated by incidence proportions, sometimes incidence densities or Kaplan–Meier estimation are proposed. These analyses either do not account for censoring, rely on a too restrictive parametric model, or ignore competing events. With the non-parametric Aalen-Johansen estimator as the “gold standard”, that is, reference estimator, potential sources of bias are investigated in an example from oncology and in simulations, for both one-sample and two-sample scenarios. The Aalen-Johansen estimator serves as a reference, because it is the proper non-parametric generalization of the Kaplan–Meier estimator to multiple outcomes. Because of potential large variances at the end of follow-up, comparisons also consider further quantiles of the observed times. To date, consequences for safety comparisons have hardly been investigated, the impact of using different estimators for group comparisons being unclear. For example, the ratio of two both underestimating or overestimating estimators may not be comparable to the ratio of the reference, and our investigation also considers the ratio of AE probabilities. We find that ignoring competing events is more of a problem than falsely assuming constant hazards by the use of the incidence density and that the choice of the AE probability estimator is crucial for group comparisons.     

Piketty comes to South Africa

One of the most valuable features of Capital and Ideology is its concern to take history seriously and consider how the emergence of different political and economic regimes relate to discourses about fairness and justice across time. This paper pushes this agenda further by acknowledging that the experience of a few developed nations should not be taken as the template for the generalized study of inequality dynamics across time and space. In this paper, we interrogate Piketty's analysis and policy proposals against specificities that are central to understanding the production and reproduction of inequalities within South Africa. We reflect on the South African case, the structure of inequality and its changes since 1994. We review a battery of policy interventions that have been implemented to address inequality in the last 25 years. We emphasize that the long shadow cast by centuries of colonialism and various forms of apartheid strongly affirm Piketty's emphasis on understanding history. But this is both affirmation and critique given the foundational, imbedded impact that this specific legacy has had on post‐apartheid society and its policies. Piketty is aware that the levels of inequality in South Africa are so high that this is “unknown territory.” We map out some of this territory to reveal how these extreme initial wealth and racial inequities inform the reproduction of inequalities in all dimensions and undermine well intentioned policies. We claim that understanding extractive histories, imbedded wealth inequalities, and complex social and political institutions allows us to understand and confront some of the reasons why even in light of progressive policies, many of which are in line with the proposals from Piketty, government interventions have thus far failed to reduce inequality.     

Managing relationships on Facebook: A long-term analysis of leading companies in Germany

The purpose of this study is to investigate how companies manage relationships with publics on social media. Based on the concepts of functional and contingency interactivity, the study examines the long-term implementation of three interactive strategies derived from research on organization-public relationships: dialogic communication, transparent communication, and informal communication. The study sheds further light on relational outputs and outcomes. The results of content analyses of leading German companies’ Facebook pages in 2012, 2015, and 2018 indicate the growing importance of dialogic communication and informal communication. There is a constant relation between dialogic communication and the extent of user interaction, with the analysis suggesting that dialogic communication is used to manage critical user comments. Hence, the long-term study contributes to a deeper understanding of professionalization in corporate social media communication. It provides evidence for PR scholars and professionals that there are effective features on Facebook for managing sustainable relationships.

Policing the Borderlands: White- and Black-American Newspaper Perceptions of Multiracial Heritage and the Idea of Race, 1996–2006

By employing a new policy of "check all that apply," the Census Bureau accommodated a mushrooming multiracial lobby demanding that its members be allowed a right to self-identification. With its implied shifting meaning of race, newspapers portrayed the reaction to this change as a firestorm of debate along racial fault lines, highlighted by Black-American inferences that this was a perilous decision. Using textual analysis, I examine from 1996 to 2006 how five Black-American and three White-American newspapers characterized multiracial people. White-American papers framed the discussion in two ways: (a) multiracial people epitomize a new era in which race has lost its bite, and (b) Black America stands in the way of their gaining their civil rights. There were also two frames for the Black-American papers: (a) The lobby advocates individual identity and is undergirded by denial or distancing from Blackness, and (b) that focus undermines Black America's future by playing into the misguided notion that race is socially insignificant.     

Who creates the jobs?

Small business start-ups create most of the new jobs in our economy. It is an attractive argument to those who want governments to support small businesses. But is it true? Or are large firms the ones that generate most jobs? Michael Anyadike-Danes, Mark Hart and Karen Bonner examine a long-running and acrimonious dispute.
