Can Inoculation Withstand Multiple Attacks?: An Examination of the Effectiveness of the Inoculation Strategy Compared to the Supportive and Restoration Strategies

This investigation introduced multiple competitive attacks in order to assess the effectiveness of inoculation treatments in protecting established attitudes in a natural setting. A four-phase experiment was conducted involving 433 participants. The results revealed that the effectiveness of refutational inoculation messages dissipated some in the face of an additional attack. Still, refutational inoculation messages proved to be more effective than supportive, restoration, and control (no message) conditions in protecting established attitudes in the face of multiple attacks. The content of an additional attack (the same as the first attack or different) did not affect the capacity of inoculation refutational messages to confer resistance to competitive attacks.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

A Matrix Model with a Singular Weight and Painlevé III

We investigate the matrix model with weight w(x):=exp(−z22x2+tx−x22)and unitary symmetry. In particular we study the double scaling limit as N→∞ and (N−−√t,Nz2)→(u1,u2), where N is the matrix dimension and the parameters (u1, u2) remain finite. Using the Deift-Zhou steepest descent method, we compute the asymptotics of the partition function when z and t are of order O(N−1/2). In this regime we discover a phase transition in the (z, N)-plane characterised by the Painlevé III equation. This is the first time that Painlevé III appears in studies of double scaling limits in Random Matrix Theory and is associated to the emergence of an essential singularity in the weighting function. The asymptotics of the partition function is expressed in terms of a particular solution of the Painlevé III equation. We derive explicitly the initial conditions in the limit Nz2→u2 of this solution

The 12^{12}C + 16^{16}O fusion reaction in carbon burning: Study at energies of astrophysical interest using the Trojan Horse Method

International audienceThe carbon-burning process in massive stars mainly occurs via the 12C +12 C. However, at temperatures higher than 109K and considering the increased abundance of 16O produced during the later stages of the heliumburning,the 12C+16O fusion can also become relevant. Moreover, 12C+16O also plays a role in the scenario of explosive carbon burning. Thus, the astrophysical energy region of interest ranges from 3 to 7.2 MeV in the center-of-mass frame. However, the various measurements of the cross-section available in the literature stop around 4 MeV, making extrapolation necessary. To solve this uncertainty and corroborate direct measurement we applied the Trojan Horse Method to three-body processes 16O(14N, α24Mg)2H and 16O(14N, p27Al)2H to study the 12C(16O, α)24Mg and 12C(16O, p)27Al reactions in their entire energy region of astrophysical interest. In this contribution, after briefly describing the method used, the experiment and the preliminary phases of the data analysis will be presented and discussed
