    The measurement of primary π±\pi^{\pm}, K±^{\pm}, p and p\overline{p} production at mid-rapidity (y<|y| < 0.5) in proton-proton collisions at s=7\sqrt{s} = 7 TeV performed with ALICE (A Large Ion Collider Experiment) at the Large Hadron Collider (LHC) is reported. Particle identification is performed using the specific ionization energy loss and time-of-flight information, the ring-imaging Cherenkov technique and the kink-topology identification of weak decays of charged kaons. Transverse momentum spectra are measured from 0.1 up to 3 GeV/cc for pions, from 0.2 up to 6 GeV/cc for kaons and from 0.3 up to 6 GeV/cc for protons. The measured spectra and particle ratios are compared with QCD-inspired models, tuned to reproduce also the earlier measurements performed at the LHC. Furthermore, the integrated particle yields and ratios as well as the average transverse momenta are compared with results at lower collision energies.Comment: 33 pages, 19 captioned figures, 3 tables, authors from page 28, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/156

Multidimensional scaling and factor analysis techniques found only limited forms of universality in evaluations across Western, Catholic/Orthodox, Muslim, and Asian country clusters. The highest consensus across cultures involved scientific innovators, with Einstein having the most positive evaluation overall. Peaceful humanitarians like Mother Theresa and Gandhi followed. There was much less cross-cultural consistency in the evaluation of negative figures, led by Hitler, Osama bin Laden, and Saddam Hussein. After more traditional empirical methods (e.g., factor analysis) failed to identify meaningful cross-cultural patterns, Latent Profile Analysis (LPA) was used to identify four global representational profiles: Secular and Religious Idealists were overwhelmingly prevalent in Christian countries, and Political Realists were common in Muslim and Asian countries. We discuss possible consequences and interpretations of these different representational profiles.This research was supported by grant RG016-P-10 from the Chiang Ching-Kuo Foundation for International Scholarly Exchange (http://www.cckf.org.tw/).

    From mindless masses to small groups: Conceptualizing collective behavior in crowd modeling.

    Computer simulations are increasingly used to monitor and predict behavior at large crowd events, such as mass gatherings, festivals and evacuations. We critically examine the crowd modeling literature and call for future simulations of crowd behavior to be based more closely on findings from current social psychological research. A systematic review was conducted on the crowd modeling literature (N = 140 articles) to identify the assumptions about crowd behavior that modelers use in their simulations. Articles were coded according to the way in which crowd structure was modeled. It was found that 2 broad types are used: mass approaches and small group approaches. However, neither the mass nor the small group approaches can accurately simulate the large collective behavior that has been found in extensive empirical research on crowd events. We argue that to model crowd behavior realistically, simulations must use methods which allow crowd members to identify with each other, as suggested by self-categorization theory

    Collective narcissism as a framework for understanding populism

    Get PDF
    Research on national collective narcissism, the belief and resentment that a nation's exceptionality is not sufficiently recognized by others, provides a theoretical framework for understanding the psychological motivations behind the support for right-wing populism. It bridges the findings regarding the economic and sociocultural conditions implicated in the rise of right-wing populism and the findings regarding leadership processes necessary for it to find its political expression. The conditions are interpreted as producing violations to established expectations regarding self-importance via the gradual repeal of the traditional criteria by which members of hegemonic groups evaluated their self-worth. Populist leaders propagate a social identity organized around the collective narcissistic resentment, enhance it, and propose external explanations for frustration of self and in-group-importance. This garners them a committed followership. Research on collective narcissism indicates that distress resulting from violated expectations regarding self-importance stands behind collective narcissism and its narrow vision of “true” national identity (the people), rejection and hostility toward stigmatized in-group members and out-groups as well as the association between collective narcissism and conspiratorial thinking

    Резюме. Представлены непосредственные и отдаленные результаты лечения 167 больных раком пищевода. Комбинированное лечение с использованием предоперационной гамма-терапии крупными фракциями было проведено 95 пациентам, хирургическое — 72. Отмечено, что предоперационное облучение не сопровождалось увеличением частоты послеоперационных осложнений, но и не способствовало улучшению отдаленных результатов операций. Ключевые слова: рак пищевода, комбинированное лечение, хирургическое лечение.Summary. Immediate and remote results of the treatment of 167 patients with esophagus cancer are reported. Combined treatment with pre-surgery large-fraction gamma-therapy was applied in 95 patients; 72 patients were operated without pre-surgery radiation treatment. Pre-surgery irradiation is shown to cause no increase in the frequency of post-operation complications. At the same time, it failed to improve the remote results of surgery. Key Words: esophagus cancer, combined treatment, surgery
