As Time Goes By: Ritualized Remembering Through Wedding Photography

The practice of remembering sometimes takes the form of ritual in order to enforce, embody and sustain social bonds and values. American wedding photography is a strong example of an instance in which remembering becomes a formalized symbolic performance through an intricate system of idealization as prescribed by various authorities. An examination of the production and exhibition practices constituting wedding photography (using various interview and observation methodologies) reveals a process through which participants solidify and maintain the social transformation marriage creates, communicate values to future generations, and cope with the implications of aging and death

User Descriptions and Interpretations of Self-Presentation through Facebook Profile Images

This article reports the findings of an open-ended qualitative survey about the choices people make when choosing profile images on Facebook. The results demonstrate that women tend to change their profile image more often and to emphasize friendship in the images they choose to display. Although both men and women are equally likely to display images of family and romantic relationships, the interpretations of such images may vary by gender. In addition, as one of the first Facebook studies to include users over 22 years old, this study provides comparative data demonstrating that older users are less likely to change their profile images frequently and more likely to display images of themselves alone. This study corroborates previous findings about the nature of self-presentation in online networking sites and offers new insights into how such impression management might vary according to age and gender

Sub-barrier Fusion Of Si + Si Systems: Does The Deformation Of 28^{28}Si Play A Role?

International audienceThis contribution reports on the results of measurements of near- and sub-barrier fusion cross sections in the system 30Si+30Si performed at the Laboratori Nazionali di Legnaro of INFN. The 30Si beam of the XTU Tandem accelerator in the energy range of 47 - 90 MeV, was delivered on a metallic 30Si target (50 µg/cm2 ) enriched to 99.64 % in mass 30. A beam electrostatic de- flector was used for the detection of evaporation residues. The excitation function obtained for 30Si+30Si has been compared with the previous data on 28Si+28Si and Coupled Channels (CC) calculations using the M3Y+repulsion potential, taking into account the low lying 2+ and 3− excitations. Reproducing the low-energy 28Si+28Si excitation function was only possible by using a weak imaginary potential, probably simulating the oblate deformation of this nucleus. On the contrary, the data on 30Si+30Si are nicely reproduced by the CC calculations without any imaginary potential (30Si has a spherical shape). The astrophysical S-factor does not show a maximum, so that there is no evidence for hindrance in the measured energy range. The logarithmic derivative of the two excitation functions highlights the difference between the two systems. Even above the barrier the two systems behave differently. This is best seen by comparing the two barrier distributions where the high energy peak observed for 28Si+28Si is not found for 30Si+30Si. This is presumably due to the stronger couplings present in 28Si and further theoretical analyses are in progress
