Online Behavioural targeted Advertising (OBA) has risen in prominence as a method to increase the effectiveness of online advertising. OBA operates by associating tags or labels to users based on their online activity and then using these labels to target them. This rise has been accompanied by privacy concerns from researchers, regulators and the press. In this paper, we present a novel method...

UNLABELLED Converging lines of evidence suggest a role for facial expressions in the pathophysiology and treatment of mood disorders. To determine the antidepressant effect of onabotulinumtoxinA (OBA) treatment of corrugator and procerus muscles in people with major depressive disorder, we conducted a double blind, randomized, placebo-controlled trial. In an outpatient clinical research center,...

Online Behavioral Advertising (OBA) is the practice of tailoring ads based on an individual’s activities online. Users have expressed privacy concerns regarding this practice, and both the advertising industry and third parties offer tools for users to control the OBA they receive. We provide the first systematic method for evaluating the effectiveness of these tools in limiting OBA. We first p...

We propose a framework for modelling situated resource-bounded agents. The framework is based on an objective ascription of intentional modalities and can be easily tailored to the system we want to model and the properties we wish to specify. As an elaboration of the framework, we introduce a logic, OBA, for describing the observations, beliefs, intentions and actions of simple agents, and sho...

Online behavioural advertising (OBA) is a special form of targeted advertising. For OBA, it is necessary to collect data about online surfing behaviour, which is usually undertaken by installing ‘cookies’. The use of cookies is heavily debated by policy makers in the US and Europe. Central to this discussion is whether users should provide informed consent prior to the installation of cookies. ...

Online Behavioural Advertising (OBA), the practice of showing advertisements based on a person’s web browsing behaviour, has become a vital component of the ad-supported web. The tracking of users’ browsing behaviour that is needed for OBA, however, raises privacy concerns. We give an overview of the OBA landscape, and describe which user information is collected, which techniques are used to p...

Online Behavioral Advertising (OBA) is the practice of tailoring ads based on an individual's online activities. We conducted a 1,505-participant online study to investigate Internet users' perceptions of OBA disclosures while performing an online task. We tested icons, accompanying taglines, and landing pages intended to inform users about OBA and provide opt-out options; these were based on p...

In the title zinc(II) coordination polymer, {[Zn(C(14)H(8)O(5))(CH(5)N)(2)]·C(4)H(9)NO}(n), each Zn(II) cation is tetra-hedrally coordinated by two carboxyl-ato O atoms of two oba anions (H(2)oba is 4,4'-oxydibenzoic acid), and two N atoms from two methyl-amine mol-ecules. Each oba anion bridges two Zn(II) cations through the two carboxyl-ate groups in a monodentate fashion, forming one-dimensi...
