Visual Expectations in Infants: Evaluating the Gaze-Direction Model

Schlesinger (in press) recently proposed a model of eye movements as a tool for investigating infants’ visual expectations. In the present study, this gaze-direction model was evaluated by (a) generating a set of predictions concerning how infants distribute their attention during possible and impossible events, and (b) testing these predictions in a replication of Baillargeon’s "car study" (1986; Baillargeon & DeVos, 1991). We find that the model successfully predicts general features of infants’ gaze direction, but not specific differences obtained during the possible and impossible events. The implications of these results for infant cognition research and theory are discussed

Contemporary psychoanalytic applications: Development and its vicissitudes

The contemporary relevance of psychoanalysis is being increasingly questioned; Off the Couch challenges this view, demonstrating that psychoanalytic thinking and its applications are both innovative and relevant, in particular to the management and treatment of more disturbed and difficult to engage patient groups. Chapters address: Clinical applications in diverse settings across the age range the relevance of psychoanalytic thinking to the practice of CBT, psychosomatics and general psychiatry the contribution of psychoanalytic thinking to mental health policy and the politics of conflict and mediation. This book suggests that psychoanalysis has a vital position within the public health sector and discusses how it can be better utilised in the treatment of a range of mental health problems. It also highlights the role of empirical research in providing a robust evidence base. Off the Couch will be essential reading for those practicing in the field of mental health and will also be useful for anyone involved in the development of mental health and public policies. It will ensure that practitioners and supervisors have a clear insight into how psychoanalysis can be applied in general healthcare

Top Partners at the LHC: Spin and Mass Measurement

If one takes naturalness seriously and also assumes a weakly coupled extension of the Standard Model (SM) then there are predictions for phenomenology that can be inferred in a model independent framework. The first such prediction is that there must be some colored particle with mass O(TeV) that cancels the top loop contribution to the quadratic divergence of the Higgs mass. In this paper we begin a model independent analysis of the phenomenology of this "top partner," t'. We make one additional assumption that it is odd under a parity which is responsible for the stability of a WIMP dark matter candidate, N. We focus on three questions to be explored at the LHC: discovery opportunities, mass determination, and spin determination of this top partner. We find that within a certain region of masses for the t' and N, t'\bar{t'} is easily discovered in the t\bar{t}+2N decay with the tops decaying fully hadronically. We show that without having to rely on other channels for new physics that for a a given t' spin the masses of t' and N can be measured using kinematic information (e.g. average MET or H_T) and total cross section. A degeneracy due to the spin remains, but with several hundred inverse fb of luminosity we demonstrate potentially useful new methods for determining the t' spin over a wide range of masses. Our methods could be useful for distinguishing supersymmetric and non-supersymmetric models.Comment: 28 pages, 5 figure

Garside families in Artin-Tits monoids and low elements in Coxeter groups

We show that every finitely generated Artin-Tits group admits a finite Garside family, by introducing the notion of a low element in a Coxeter group and proving that the family of all low elements in a Coxeter system (W, S) with S finite includes S and is finite and closed under suffix and join with respect to the right weak order

COIN is dead - long live transformation

Donald Rumsfeld was right. Force transformation works. The techniques that led to the initial victories in Afghanistan in 2001 were precisely those that produced success in Libya in 2011.1 Small-scale deployments of special forces backed by precision strike and deep attack capabilities used to support an allied indigenous armed group proved an effective military tool for achieving specific strategic outcomes. In contrast, the results of large-scale troop deploy- ments as part of counterinsurgency (COIN), stabilization and nation-building activities over the past ten years in Iraq and Afghanistan have been less defini- tive. Despite intensive investment in blood, treasure, and military effort, the precise long-term outcomes of these two campaigns remain unclear and will be open to debate for years to come. This challenging operational experience has, however, highlighted some necessary and enduring truths about the use of military force. This paper explores those in light of the last ten years of counterinsurgenc

Estimating Housing Demand with an Application to Explaining Racial Segregation in Cities

We present a three-stage estimation procedure to recover willingness to pay for housing attributes. In the first stage, we estimate a non-parametric hedonic home price function. Second, we recover each consumer's taste parameters for product characteristics using first order conditions for utility maximization. Finally, we estimate the distribution of household tastes as a function of household demographics. As an application of our methods, we compare alternative explanations for why blacks choose to live in center cities while whites suburbanize.
