Performance of missing transverse momentum reconstruction with the ATLAS detector using proton-proton collisions at s√ = 13 TeV

Abstract: The performance of the missing transverse momentum ( ETmiss ) reconstruction with the ATLAS detector is evaluated using data collected in proton-proton collisions at the LHC at a centre-of-mass energy of 13 TeV in 2015. To reconstruct ETmiss , fully calibrated electrons, muons, photons, hadronically decaying τ-leptons , and jets reconstructed from calorimeter energy deposits and charged-particle tracks are used. These are combined with the soft hadronic activity measured by reconstructed charged-particle tracks not associated with the hard objects. Possible double counting of contributions from reconstructed charged-particle tracks from the inner detector, energy deposits in the calorimeter, and reconstructed muons from the muon spectrometer is avoided by applying a signal ambiguity resolution procedure which rejects already used signals when combining the various ETmiss contributions. The individual terms as well as the overall reconstructed ETmiss are evaluated with various performance metrics for scale (linearity), resolution, and sensitivity to the data-taking conditions. The method developed to determine the systematic uncertainties of the ETmiss scale and resolution is discussed. Results are shown based on the full 2015 data sample corresponding to an integrated luminosity of 3.2fb-1 .

Frequency and Severity of Psychological Abuse in a Dating Population

Abstract: The Psychological Maltreatment of Women Inventory was modified and used to assess the occurrence of psychological abuse in 1,625 college-age males and females. Six reliable factors were extracted from the scale reflecting the following concepts: positive behaviors, diminishment of self-esteem, verbal abuse, social and emotional control, jealousy, and withdrawal. Males currently involved in a relationship at the time the questionnaire was administered reported higher levels of psychological abuse and fewer positive behaviors than did females. However, the occurrence of psychologically abusive behaviors within a relationship were likely to result in a lower relationship satisfaction rating for both males and females. In addition, women in more formally committed relationships were most likely to report psychological abuse. Finally, the termination of a relationship was associated with an absence of positive behaviors, rather than a high frequency of negative behaviors. These findings are discussed with resp...

Perceiving Your Group’s Future to Be in Jeopardy: Extinction Threat Induces Collective Angst and the Desire to Strengthen the Ingroup

Abstract: Collective angst reflects concern about the ingroup’s future vitality. In four studies, the authors examined the impact of ingroup extinction threat on the experience of collective angst. In Study 1, collective angst was elicited in response to a physical or symbolic ingroup extinction threat compared to a no-threat control group. In Study 2, the extent to which French Canadians expressed collective angst because of the perceived extinction threat posed by English Canada predicted desire to engage in ingroup strengthening behaviors. In Studies 3 and 4, the impact of a historical extinction threat was assessed. The extent to which Jewish people expressed thinking about (Study 3) or were reminded of the Holocaust (Study 4) resulted in an increased desire to engage in ingroup strengthening behaviors. Collective angst acted as a mediator of these effects. Implications of extinction threat for both intragroup and intergroup behavior are discussed.
