    Equation of state of the neutron star matter, and the nuclear symmetry energy

    Full text link
    The nuclear mean-field potentials obtained in the Hartree-Fock method with different choices of the in-medium nucleon-nucleon (NN) interaction have been used to study the equation of state (EOS) of the neutron star (NS) matter. The EOS of the uniform NS core has been calculated for the npeμe\mu composition in the β\beta-equilibrium at zero temperature, using version Sly4 of the Skyrme interaction as well as two density-dependent versions of the finite-range M3Y interaction (CDM3Ynn and M3Y-Pnn), and versions D1S and D1N of the Gogny interaction. Although the considered effective NN interactions were proven to be quite realistic in numerous nuclear structure and/or reaction studies, they give quite different behaviors of the symmetry energy of nuclear matter at supranuclear densities that lead to the \emph{soft} and \emph{stiff} scenarios discussed recently in the literature. Different EOS's of the NS core and the EOS of the NS crust given by the compressible liquid drop model have been used as input of the Tolman-Oppenheimer-Volkov equations to study how the nuclear symmetry energy affects the model prediction of different NS properties, like the cooling process as well as the gravitational mass, radius, and moment of inertia.Comment: To be published in Physical Review

    Cross-Cultural Differences in Interpersonal and Intrapersonal Understandings of Forgiveness

    Most theorizing about forgiveness conceptualize forgiveness as an intrapersonal process in which negative feelings are transformed into positive ones, with the goal of inner peace for the forgiver. Forgiveness viewed as an interpersonal process, in contrast, focuses on behaviors, such as reconciliation, that lead to the restoration of social harmony. Several studies have demonstrated that the understanding and practice of forgiveness differs across cultures. We examined the hypothesis that North Americans understand forgiveness as more of an intrapersonal phenomenon and less of an interpersonal phenomenon relative to Asians. A sample of 153 participants recruited through Facebook completed an online survey. Findings generally support the hypothesis: North Americans endorsed intrapersonal over interpersonal understandings of forgiveness, Southeast Asians endorsed interpersonal over intrapersonal understandings, and South Asians were closely split between the two definitions. The current findings suggest that collectivistic forgiveness is not a unitary construct, and that the application of theory and therapy models based on Western conceptions of forgiveness to Asian populations may be inaccurate and even harmful. Future research should examine forgiveness across collectivistic cultures. Additionally, cross-cultural research on forgiveness should use specific affective, cognitive, and behavioral terms when assessing a participant’s level of forgiveness; broad questions assessing a participant’s general forgiveness may be difficult to interpret and compare cross-culturally

    The Effects of War and Migration Trauma on Southeast Asian Families in the United States

    Get PDF
    This review article focuses on Southeast Asian (SEA) families, which include Vietnamese, Laotian, Hmong, and Cambodian ethnic groups, comprising about three million people in the United States. Although many differences exist among SEAs, they share experiences of war and migration-related trauma and losses that continue to have long-term effects on their families and individual well-being within and across generations. Research and practice work with SEA families and individuals requires in depth knowledge of their experiences before, during, and after migration to the U.S. This article on SEA families, although not exhaustive in its coverage, highlights the following topics: SEA populations in the U.S., migration history, resettlement and adaptation in the U.S., mental health issues of SEAs, traditional SEA family, migration and family formation, migration and family relationships, migration and family in later life, and implications for research and practice with SEA families and individuals

    Revisiting glueball wave functions at zero and finite temperature

    Full text link
    We study the sizes and thermal properties of glueballs in a three dimensional compact Abelian gauge model on improved lattice. We predict the radii of 0.60\sim 0.60 and 1.12\sim 1.12 in the units of string tension, or 0.28\sim 0.28 and 0.52\sim 0.52 fm, for the scalar and tensor glueballs, respectively. We perform a well controlled extrapolation of the radii to the continuum limit and observe that our results agree with the predicted values. Using Monte Carlo simulations, we extract the pole-mass of the lowest scalar and tensor glueballs from the temporal correlators at finite temperature. We see a clear evidence of the deconfined phase, and the transition appears to be similar to that of the two-dimensional XY model as expected from universality arguments. Our results show no significant changes in the glueball wave functions and masses in the deconfined phase.Comment: 8 pages, 10 figure
