Many researchers interested In the socializing effects of pornography have found heuristic utility in the sexual script acquisition, activation, application model (

AM) of mediated sexual ...socialization. Studies have emphasized overall pornography/sexual behavior associations, however, rather than mediating sexual beliefs that a
3
AM perspective suggests should underlie such associations. The present study used data from a campus-representative probability sample to examine whether linkages between pornography use and heterosexual-identified collegiate men's choking of sexual partners is mediated by the belief that sexual choking is pleasurable, the belief that sexual choking is safe, and the disbelief that sexual choking requires consent from the person being choked. Sexual choking has been increasingly identified as a focal point of contemporary mixed-sex pornography as well as young men's sexual behavior; it can also result in adverse health and legal consequences. Results were consistent with a sequential model positing that consuming pornography more frequently leads to more exposure to pornographic depictions of sexual choking, which in turn predicts a higher likelihood of choking sexual partners through the belief that sexual choking is pleasurable, the belief that sexual choking is safe, and the disbelief that sexual choking requires consent from the person being choked.
A 4-year-old male Japanese Shiba Inu presented with recurrent chylothorax. The thoracic duct was successfully imaged using computed tomography after the injection of an iodine contrast agent into the ...subcutaneous tissue surrounding the anus. The thoracic duct was successfully ligated and pericardectomy performed via an open thoracotomy. Pleural effusion improved but relapsed a week after the surgery. A second lymphography revealed a collateral thoracic duct that was not detected during the first lymphography. The collateral duct was ligated and chylothorax was resolved after the second surgery. The lymphography applied in this study was minimally-invasive and easily provided images of the thoracic duct in a dog with chylothorax.
A short super-X divertor (SXD) is proposed as an option for the Demo divertor, where the field line length from the divertor null to the outer target was largely increased compared to a similar-size ...conventional divertor. Physics and engineering design studies for a 3 GW-level fusion power Demo reactor (SlimCS) (Tobita et al., 2009) have recently progressed. Minimal number of the divertor coils were installed inside the toroidal field coil, i.e. interlink-winding. Arrangement of the poloidal field coils and their currents were determined, taking into account of the engineering design such as vacuum vessel and the neutron shield structures, and the divertor maintenance scenario. Divertor plasma simulation showed that significant radiation region is produced between the super-X null and the target. Radiation loss in the divertor was increased, producing fully detached plasmas efficiently. Advantages of the short SXD were demonstrated, but the total peak heat load was a marginal level (10MWm−2) for the engineering design.
Concerns about the problematic nature of internet use have been discussed since the inception of the internet. Internet addiction, problematic internet use (PIU), and the deficient self-regulation of ...internet use are some issues studied in this domain. Some regard these conditions as genuine disorders that cause disruptions in one’s life. Others criticize their legitimacy, claiming that functional impairment associated with internet use is indicative of primary psychosocial problems and has little to do with the internet. The purpose of this investigation was to understand whether cognitive preoccupation and uncontrolled use, components of PIU, are part of a unique disorder or are symptomatic of underlying psychosocial problems. This research tested the mediating role of PIU in the relationships between psychosocial problems (i.e., social anxiety, loneliness, and depression) and impairment of interpersonal relationships and vocational performance in two studies. Different conclusions were reached based on the methodological design of the study; however, the findings generally supported the mediation of PIU.
One of the most consistent findings in content analyses of popular, commonly consumed pornography is the near absence of condoms. A recent meta-analysis found that pornography use is associated with ...an increased likelihood of condomless sex, but the studies available for analysis rarely included measures of potential cognitive mediators underlying the association. Following the sexual script acquisition, activation, application model (
3
AM) of mediated sexual socialization and the differential susceptibility to media effects model (DSMM), the present study examined whether linkages between pornography use and condomless sex are mediated by perceived similarity to actors in pornography and heightened perceptions of pornography's utility and social realism. Social realism and similarity mediated the association between pornography consumption frequency and condomless sex in simple mediation models, but only social realism remained significant in a parallel process model inclusive of all three mediators.
•The overall plant system related to the water-cooling system has been developed for JA DEMO.•Management of tritium concentration in the primary cooling system is clarified for JA DEMO.•Tritium ...permeation from the primary to the secondary cooling system was found to be less than the Japanese PWR restriction value.•A pressure suppression pool is effective to suppress the tritium release to the environment at the ex-vessel LOCA.•The system diagram of water coolant and tritium was also delineated for JA DEMO.
The conceptual design of Japan’s fusion demonstration plant (JA DEMO) is now being developed. In this paper, an overall plant system concept related to tritium handling in the water-cooling system is developed to give a concrete shape to the present JA DEMO concept as an electric power plant. The basic condition of tritium permeation from the in-vessel components to the primary cooling system is evaluated to be 5.7 g-T/day. The tritium concentration of the primary coolant is assumed to be 1 TBq/kg similar to the heavy water reactor condition. The capacity of the water detritiation system (WDS) is assessed, and the bypass feed water from the primary cooling loop is evaluated to be 94 kg/h under the tritium extraction efficiency of 0.96. Based on those specific parameters, the existing WDS in the heavy water reactor is found to be applicable to that of JA DEMO. Configuration of the primary heat transfer system (PHTS) is also discussed. Based on the heavy water reactor experience, tritium permeation through a steam generator (SG) to the secondary cooling system in PHTS is evaluated at 11.77TBq/year/loop (318 Ci/year/loop), which is found to be less than the restricted amount of tritium disposal for a pressurized water reactor in Japan. The key effect of the heavy water reactor experience is reduction of tritium permeation by oxide layer formed on SG pipes. Finally, a confinement concept of tritium release from PHTS is discussed under the condition of ex-vessel loss of coolant accident (LOCA). A pressure suppression system is installed to prevent the upper tokamak hall from pressurizing at the ex-vessel LOCA, and the tritium leakage from the upper tokamak hall is consequently restrained. The resultant early public dose at the plant site boundary can be reduced to 1.8 mSv, which is negligibly smaller than 100 mSv of the no-evacuation limit recommended by IAEA.
Research on parental knowledge and positive adolescent adjustment suggests that more accurate levels of the former increase the likelihood of the latter. Despite a significant body of literature ...correlating adolescent pornography use with negative adolescent adjustment, however, only a handful of studies have compared parents’ beliefs about their children’s pornography use with adolescents’ reports and just a few of these have been carried out in the U.S. The present study employed national probability data gathered from 614 parent–adolescent dyads in the U.S. as a further step toward bolstering this important area of parent–child research. Parents were 44.78 years old on average (SD = 7.76). Mothers comprised 55.80% of parents (fathers were 44.20%). Children were 15.97 years old on average (SD = 1.38). Daughters comprised 50.20% of children (sons were 49.80%). Boys were more likely to report pornography use and learning across a range of pornography genres and sexual domains. Parents accurately estimated the direction of many of these gender differences, but still consistently underestimated both sons’ and daughters’ exposure to and socialization from pornography. Interestingly, although parents were more likely to believe that sons than daughters had viewed and learned from pornography, their degree of underestimation was larger for sons. Mothers’ and fathers’ beliefs were consistently indistinguishable at the main effect level and interacted with child gender in only one instance. Results are discussed in relation to the moral panic and risk underestimation perspectives on youth and media effects.
