Personalization in Social Retargeting – A Field Experiment

This study compares the effectiveness of product- and category-specific advertising personalization in Social Retargeting. Social Retargeting combines the features of social advertising, targeting consumers based on social connections, and retargeting, using consumers’ browsing behavior to personalize ad content. We conducted a large-scale randomized field experiment in collaboration with a major e-retailer. Contradicting prior empirical findings, our results indicate that product-specific ads outperform less personalized category-specific ads. While theory suggests a positive effect, we find that social targeting decreases the performance of personalized ads. Surprisingly, socially targeted consumers are not more responsive to product-specific ads. We show that our results remain robust and are driven by ad personalization when controlling for temporal targeting and how deep consumers browse the e-retailer’s website. Our study contributes to the IS and marketing literature related to personalization in digital advertising and provides valuable suggestions for firms’ personalization strategies

Don’t Take It Personally: The Effect of Explicit Targeting in Advertising Personalization

Firms increasingly use consumers’ information to personalize their communication. Personalized advertisements, targeted based on users’ past behavior, offer users relevant product information that fits their preferences. In this study, we investigate the implications of explicit targeting, making the underlying targeting mechanism explicit to consumers, and ad message framing, in terms of utilitarian or hedonic product benefits. In a large-scale field experiment in which we run a campaign for a mobile application, we show that explicit targeting reduces advertising effectiveness pointing towards increased consumer privacy concerns. While utilitarian ad messages reinforce the negative effect of explicit targeting, the use of hedonic ad messages alleviates such a negative effect. Our study contributes to IS literature on advertising personalization and the personalization privacy paradox. We provide practical insights for firms that can be used in the design and implementation of personalized advertising campaigns

On the design of reliable libraries

Software libraries are an important instrument for achieving reuse of both designs and programs. This goal is supported by several non-functional properties of libraries. Specifically, a library should be flexible by allowing components to be reused in different contexts with possibly changing requirements. However, reuse must not introduce new errors: the library components must remain correct in unknown contexts (robustness). Most common object-oriented libraries focus unilaterally on flexibility, neglecting robustness requirements. This paper investigates the trade-off between flexibility and robustness. We show that the desire for both flexible reuse and robustness can be met. Design patterns is identified as an important tool for structuring large object-oriented class libraries. The concepts discussed in this article have been realized in KARLA, an object-oriented library of algorithms and data structures, that currently contains more than 200 classes, and that is continuously bein..

Standardized or simple effect size: what should be reported?

It is regarded as best practice for psychologists to report effect size when disseminating quantitative research findings. Reporting of effect size in the psychological literature is patchy – though this may be changing – and when reported it is far from clear that appropriate effect size statistics are employed. This paper considers the practice of reporting point estimates of standardized effect size and explores factors such as reliability, range restriction and differences in design that distort standardized effect size unless suitable corrections are employed. For most purposes simple (unstandardized) effect size is more robust and versatile than standardized effect size. Guidelines for deciding what effect size metric to use and how to report it are outlined. Foremost among these are: i) a preference for simple effect size over standardized effect size, and ii) the use of confidence intervals to indicate a plausible range of values the effect might take. Deciding on the appropriate effect size statistic to report always requires careful thought and should be influenced by the goals of the researcher, the context of the research and the potential needs of readers

How does the relaxation of a supercooled liquid depend on its microscopic dynamics?

Using molecular dynamics computer simulations we investigate how the relaxation dynamics of a simple supercooled liquid with Newtonian dynamics differs from the one with a stochastic dynamics. We find that, apart from the early beta-relaxation regime, the two dynamics give rise to the same relaxation behavior. The increase of the relaxation times of the system upon cooling, the details of the alpha-relaxation, as well as the wave vector dependence of the Edwards-Anderson-parameters are independent of the microscopic dynamics.Comment: 6 pages of Latex, 4 figure

Lung transplantation for acute respiratory distress syndrome:A multicenter experience

Acute respiratory distress syndrome (ARDS) is a rapidly progressive lung disease with a high mortality rate. Although lung transplantation (LTx) is a well-established treatment for a variety of chronic pulmonary diseases, LTx for acute lung failure (due to ARDS) remains controversial. We reviewed posttransplant outcome of ARDS patients from three high-volume European transplant centers. Demographics and clinical data were collected and analyzed. Viral infection was the main reason for ARDS (n = 7/13, 53.8%). All patients were admitted to ICU and required mechanical ventilation, 11/13 were supported with ECMO at the time of listing. They were granted a median LAS of 76 (IQR 50-85) and waited for a median of 3 days (IQR 1.5-14). Postoperatively, median length of mechanical ventilation was 33 days (IQR 17-52.5), median length of ICU and hospital stay were 39 days (IQR 19.5-58.5) and 54 days (IQR 43.5-127). Prolongation of peripheral postoperative ECMO was required in 7/13 (53.8%) patients with a median duration of 2 days (IQR 2-7). 30-day mortality was 7.7%, 1 and 5-year survival rates were calculated as 71.6% and 54.2%, respectively. Given the lack of alternative treatment options, the herein presented results support the concept of offering live-saving LTx to carefully selected ARDS patients

Ground Support Software for Spaceborne Instrumentation

ION is a system of ground support software for the ion and neutral mass spectrometer (INMS) instrument aboard the Cassini spacecraft. By incorporating commercial off-the-shelf database, Web server, and Java application components, ION offers considerably more ground-support-service capability than was available previously. A member of the team that operates the INMS or a scientist who uses the data collected by the INMS can gain access to most of the services provided by ION via a standard pointand click hyperlink interface generated by almost any Web-browser program running in almost any operating system on almost any computer. Data are stored in one central location in a relational database in a non-proprietary format, are accessible in many combinations and formats, and can be combined with data from other instruments and spacecraft. The use of the Java programming language as a system-interface language offers numerous capabilities for object-oriented programming and for making the database accessible to participants using a variety of computer hardware and software
