Constraints on the spin-parity and anomalous HVV couplings of the Higgs boson in proton collisions at 7 and 8 TeV

Abstract: The study of the spin-parity and tensor structure of the interactions of the recently discovered Higgs boson is performed using the H to ZZ, Z gamma*, gamma* gamma* to 4 l, H to WW to l nu l nu, and H to gamma gamma decay modes. The full dataset recorded by the CMS experiment during the LHC Run 1 is used, corresponding to an integrated luminosity of up to 5.1 inverse femtobarns at a center-of-mass energy of 7 TeV and up to 19.7 inverse femtobarns at 8 TeV. A wide range of spin-two models is excluded at a 99% confidence level or higher, or at a 99.87% confidence level for the minimal gravity-like couplings, regardless of whether assumptions are made on the production mechanism. Any mixed-parity spin-one state is excluded in the ZZ and WW modes at a greater than 99.999% confidence level. Under the hypothesis that the resonance is a spin-zero boson, the tensor structure of the interactions of the Higgs boson with two vector bosons ZZ, Z gamma, gamma gamma, and WW is investigated and limits on eleven anomalous contributions are set. Tighter constraints on anomalous HVV interactions are obtained by combining the HZZ and HWW measurements. All observations are consistent with the expectations for the standard model Higgs boson with the quantum numbers J[PC]=0[++].

Statistical Computations on Grassmann and Stiefel Manifolds for Image and Video-Based Recognition

Abstract: In this paper, we examine image and video-based recognition applications where the underlying models have a special structure-the linear subspace structure. We discuss how commonly used parametric models for videos and image sets can be described using the unified framework of Grassmann and Stiefel manifolds. We first show that the parameters of linear dynamic models are finite-dimensional linear subspaces of appropriate dimensions. Unordered image sets as samples from a finite-dimensional linear subspace naturally fall under this framework. We show that an inference over subspaces can be naturally cast as an inference problem on the Grassmann manifold. To perform recognition using subspace-based models, we need tools from the Riemannian geometry of the Grassmann manifold. This involves a study of the geometric properties of the space, appropriate definitions of Riemannian metrics, and definition of geodesics. Further, we derive statistical modeling of inter and intraclass variations that respect the geometry of the space. We apply techniques such as intrinsic and extrinsic statistics to enable maximum-likelihood classification. We also provide algorithms for unsupervised clustering derived from the geometry of the manifold. Finally, we demonstrate the improved performance of these methods in a wide variety of vision applications such as activity recognition, video-based face recognition, object recognition from image sets, and activity-based video clustering.

A Theory of Blame

Abstract: We introduce a theory of blame in five parts. Part 1 addresses what blame is: a unique moral judgment that is both cognitive and social, regulates social behavior, fundamentally relies on social cognition, and requires warrant. Using these properties, we distinguish blame from such phenomena as anger, event evaluation, and wrongness judgments. Part 2 offers the heart of the theory: the Path Model of Blame, which identifies the conceptual structure in which blame judgments are embedded and the information processing that generates such judgments. After reviewing evidence for the Path Model, we contrast it with alternative models of blame and moral judgment (Part 3) and use it to account for a number of challenging findings in the literature (Part 4). Part 5 moves from blame as a cognitive judgment to blame as a social act. We situate social blame in the larger family of moral criticism, highlight its communicative nature, and discuss the darker sides of moral criticism. Finally, we show how the Path Model ...

Parenting behaviour and adolescent behavioural and emotional problems: The role of self-control:

Abstract: Cross-sectional data from 1359 boys and girls aged 10–14 years investigated whether parenting behaviours are directly or indirectly (through building self-control) associated with emotional (depression, stress, low self-esteem) and behavioural (delinquency, aggression) problems among adolescents. Replicating existing findings, both types of problems were directly, negatively related to adaptive parenting behaviour (high parental acceptance, strict control and monitoring, and little use of manipulative psychological control). Extending existing findings, self-control partially mediated the link between parenting behaviour and adolescent emotional and behavioural problems. Contrary to earlier suggestions, there was no sign that high self-control was associated with drawbacks or increased risk of psychosocial problems.
