When accuracy hurts, and when it helps: a test of the empathic accuracy model in marital interactions.

Abstract: This study tested predictions from W. Ickes and J. A. Simpson's (1997, 2001) empathic accuracy model. Married couples were videotaped as they tried to resolve a problem in their marriage. Both spouses then viewed a videotape of the interaction, recorded the thoughts and feelings they had at specific time points, and tried to infer their partner's thoughts and feelings. Consistent with the model, when the partner's thoughts and feelings were relationship-threatening (as rated by both the partners and by trained observers), greater empathic accuracy on the part of the perceiver was associated with pre-to-posttest declines in the perceiver's feelings of subjective closeness. The reverse was true when the partner's thoughts and feelings were nonthreatening. Exploratory analyses revealed that these effects were partially mediated through observer ratings of the degree to which partners tried to avoid the discussion issue.

Miseducating Teachers about the Poor: A Critical Analysis of Ruby Payne's Claims about Poverty

Abstract: Background/Context This is the first research study to examine the content basis of Payne's in-service teacher education program, A Framework for Understanding Poverty, though others who have reviewed the book have agreed with our analysis. The study took place within a policy context in which the federal government, with the passage of the No Child Left Behind Act (2002), created a new category of students (economically disadvantaged) whose test scores would be monitored by officials in the U. S. Department of Education. This law ensures that the improvement of poor children's test scores becomes a major concern of every public school in the country. These federal requirements have fueled the demand for professional development programs such as that offered by Ruby Payne and her Aha! Process, Inc. Purpose This article reports on an examination of the content of Ruby Payne's professional development offerings, as represented in A Framework for Understanding Poverty. Given the immense popularity of the program, an assessment of its representations of poor people is warranted and significant. We analyzed the relationship between Payne's claims and the existing research about low-income individuals and families. This study of Payne's work provides administrators and teachers with an evaluation of the reliability of Payne's claims. It also provides scholars in education, anthropology, sociology, and related fields with a description and critique of one of the more common conversations that is engaging teachers about the nature of the lives of many of their students, and the struggle to identify directions in which to improve schooling for the most vulnerable students in the education system. Research Design This is a qualitative research study whose data were derived from an analysis of A Framework for Understanding Poverty. Conclusions/Recommendations Our critical analysis of Payne's characterizations of people living in poverty indicates that her work represents a classic example of what has been identified as deficit thinking. We found that her truth claims, offered without any supporting evidence, are contradicted by anthropological, sociological and other research on poverty. We have demonstrated through our analysis that teachers may be misinformed by Payne's claims. As a consequence of low teacher expectations, poor students are more likely to be in lower tracks or lower ability groups and their educational experience more often dominated by rote drill and practice.

Readiness of the ATLAS Tile Calorimeter for LHC collisions.

Abstract: The Tile hadronic calorimeter of the ATLAS detector has undergone extensive testing in the experimental hall since its installation in late 2005. The readout, control and calibration systems have been fully operational since 2007 and the detector has successfully collected data from the LHC single beams in 2008 and first collisions in 2009. This paper gives an overview of the Tile Calorimeter performance as measured using random triggers, calibration data, data from cosmic ray muons and single beam data. The detector operation status, noise characteristics and performance of the calibration systems are presented, as well as the validation of the timing and energy calibration carried out with minimum ionising cosmic ray muons data. The calibration systems’ precision is well below the design value of 1%. The determination of the global energy scale was performed with an uncertainty of 4%.

Search for Higgs boson pair production in the γ γ bb¯ final state with 13 TeV pp collision data collected by the ATLAS experiment

Abstract: A search is performed for resonant and non-resonant Higgs boson pair production in the $ \upgamma \upgamma b\overline{b} $ final state. The data set used corresponds to an integrated luminosity of 36.1 fb$^{−1}$ of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. No significant excess relative to the Standard Model expectation is observed. The observed limit on the non-resonant Higgs boson pair cross-section is 0.73 pb at 95% confidence level. This observed limit is equivalent to 22 times the predicted Standard Model cross-section. The Higgs boson self-coupling (κ$_{λ}$ = λ$_{HHH}$/λ$_{HHH}^{SM}$ ) is constrained at 95% confidence level to −8.2 < κ$_{λ}$ < 13.2. For resonant Higgs boson pair production through $ X\to HH\to \upgamma \upgamma b\overline{b} $ , the limit is presented, using the narrow-width approximation, as a function of m$_{X}$ in the range 260 GeV < m$_{X}$ < 1000 GeV. The observed limits range from 1.1 pb to 0.12 pb over this mass range.
