Wdzięczność a poczucie długu w sytuacji otrzymania pomocy

The aim of the study was to show the relationship between the emotion of gratitude and the sense of debt and other emotions, as well as the relationship between the emotion of gratitude and debt and dispositional gratitude. The purpose of the study was also to show whether gratitude correlates with a sense of debt and whether it is related to other emotions to a different extent. The aim of the study was also to determine to whom the respondents are grateful and to whom they most often feel indebted. In the study, there were included 148 students of nursing, emergency medical services and pedagogy (100 women, 48 men). The GQ-6 tool of Michael E. McCullough and Robert Emmons’ dispositional gratitude was used, in the Polish adaptation of Marlena Kossakowska and Piotr Kwiatek, the own scale of the intensity of emotions and experimental manipulation aimed at arousing the emotions of gratitude or indebtedness. Gratitude was positively related to joy more strongly in women. Only in women was indebtedness associated with joy and guilt. In the condition of gratitude, gratitude was not associated with a sense of debt, while in the condition of indebtedness, indebtedness was positively related to gratitude. In both conditions, the respondents more often felt the emotion of gratitude than indebtedness. In condition of gratitude, the respondents felt significantly more gratitude than negative emotions. In the condition of indebtedness, the respondents felt more debt than other negative emotions. The respondents more often felt gratitude towards their loved ones, and more often they felt gratitude than debt.Celem badania było wskazanie zależności między emocją wdzięczności oraz poczuciem długu a innymi emocjami, związków między emocją wdzięczności i długu a wdzięcznością dyspozycyjną, a także wykazanie, czy wdzięczność koreluje z poczuciem długu i czy w różnym zakresie wiąże się z innymi emocjami oraz określenie, komu badani są wdzięczni i wobec jakich osób najczęściej odczuwają dług. Badaniem objęto 148 studentów pielęgniarstwa, ratownictwa medycznego i pedagogiki (100 kobiet, 48 mężczyzn). Zastosowano narzędzie do pomiaru wdzięczności dyspozycyjnej GQ-6 Michaela E. McCullougha i Roberta Emmonsa w polskiej adaptacji Marleny Kossakowskiej i Piotra Kwiatka, skalę własną nasilenia emocji oraz manipulację eksperymentalną służącą wzbudzeniu emocji wdzięczności i długu. Wdzięczność była dodatnio powiązana z radością silniej u kobiet. Tylko u kobiet poczucie długu wiązało się z radością i z poczuciem winy. W warunku wzbudzenia wdzięczności nie wiązała się ona z poczuciem długu, natomiast w warunku wzbudzenia poczucia długu wiązał się on dodatnio z wdzięcznością. W obu warunkach badani częściej odczuwali emocję wdzięczności niż długu. W warunku wzbudzenia wdzięczności badani odczuwali istotnie więcej wdzięczności niż emocji negatywnych. W warunku wzbudzenia długu badani odczuwali więcej poczucia długu niż pozostałych emocji negatywnych. Badani częściej odczuwali wdzięczność wobec osób najbliższych, częściej też odczuwano wdzięczność niż dług

Collective flow in heavy ion collisions at intermediate energies

We present results of a flow analysis for the set of reactions of 124,129Xe projectiles and 112,124Sn targets at incident energies 100 and 150 A MeV studied with the INDRA detector at GSI. The dependence on centrality and on p_t of the directed and elliptic flow are determined for isotopically selected reaction products with Z \le 3. The flow parameters v_1 and v_2, in general, follow expected trends but isotopic effects are small.Comment: 3 pages, 2 figures, contributed talk at INPC, Tokyo, June 3-8, 2007, to appear in the proceeding

Constraining properties of neutron stars with heavy-ion reactions in terrestrial laboratories

Heavy-ion reactions provide a unique means to investigate the equation of state (EOS) of neutron-rich nuclear matter, especially the density dependence of the nuclear symmetry energy $E_{sym}(\rho)$. The latter plays an important role in understanding many key issues in both nuclear physics and astrophysics. Recent analyses of heavy-ion reactions have already put a stringent constraint on the $E_{sym}(\rho)$ around the saturation density. This subsequently allowed us to constrain significantly the radii and cooling mechanisms of neutron stars as well as the possible changing rate of the gravitational constant G.Comment: 6 pages. Talk given at the Nuclear Physics in Astrophysics III, Dresden, Germany, March 26-31, 2007. To appear in a special volume of J. of Phys.

The Ziggurat Method for Generating Random Variables

We provide a new version of our ziggurat method for generating a random variable from a given decreasing density. It is faster and simpler than the original, and will produce, for example, normal or exponential variates at the rate of 15 million per second with a C version on a 400MHz PC. It uses two tables, integers ki, and reals wi. Some 99% of the time, the required x is produced by: Generate a random 32-bit integer j and let i be the index formed from the rightmost 8 bits of j. If j < k, return x = j x wi. We illustrate with C code that provides for inline generation of both normal and exponential variables, with a short procedure for settting up the necessary tables

Tm3+/Ho3+ codoped tellurite fiber laser

Continuous-wave and Q-switched lasing from a Tm 3+ /Ho 3+ codoped tellurite fiber is reported. An Yb 3+ /Er 3+ -doped silica fiber laser operating at 1.6μm was used as an in-band pump source, exciting the Tm 3+ ions into the F 4 3 level. Energy is then nonradiatively transferred to the upper laser level, the I 7 5 state of Ho 3+ . The laser transition is from the I 7 5 level to the I 8 5 level, and the resulting emission is at 2.1μm . For continuous wave operation, the slope efficiency was 62% and the threshold 0.1W ; the maximum output demonstrated was 0.16W . Mechanical Q switching resulted in a pulse of 0.65μJ energy and 160ns duration at a repetition rate of 19.4kHz

The universal instability in general geometry

The "universal" instability has recently been revived by Landreman, Antonsen and Dorland [1], who showed that it indeed exists in plasma geometries with straight (but sheared) magnetic field lines. Here it is demonstrated analytically that this instability can be present in more general sheared and toroidal geometries. In a torus, the universal instability is shown to be closely related to the trapped-electron mode, although the trapped-electron drive is usually dominant. However, this drive can be weakened or eliminated, as in the case in stellarators with the maximum-$J$ property, leaving the parallel Landau resonance to drive a residual mode, which is identified as the universal instability
