Generation Z users' attitudes towards online video advertising : Youtube video platform

Generation Z has been in a high-pressure environment for a long time, whether studying or working, and everyone is in a fast-paced attitude of life. The online world, especially video software, is very popular among the Generation Z crowd because these video software can provide fast, convenient, and decompressed content. And when browsing videos, one thing that has to be mentioned is the advertisements. The frequent presence of ads has led to the rapid growth of membership on various platforms. However, YouTube is the most popular video sharing platform in the world. This paper investigates the attitude of the Generation Z user group towards online video ad placement on YouTube. Also, this paper studies and analyzes the value perceptions of Generation Z users. Also, this paper investigates whether users are equally influenced by the experience of ads on similar video software platforms and whether they have common influencing factors. This paper focuses on the impact of three ad delivery methods on Generation Z users' experience, including skippable ads, non-skippable ads, and five-second skippable ads. This paper will use qualitative research methods to conduct one-on-one interviews with respondents to study and analyze the results

Spontaneous Formation of Vesicles from Mixed Amphiphiles with Dispersed Molecular Weight: Monte Carlo Simulation

The spontaneous formation of vesicles from amphiphiles with dispersed molecular weight (MW) as well as with mono-MW has been studied by a lattice Monte Carlo simulation. Both pure and mixed amphiphiles were self-assembled into vesicles under appropriate conditions. When mixed amphiphiles were examined, the amphiphiles with longer hydrophilic blocks preferred to segregate into the outer monolayer of the resultant vesicles, which is consistent with the experimental observations in recent literature. The kinetic study reveals that the increase of vesicle size is mainly caused by the mechanism of vesicle fusion at the early stage, and the evaporation−condensation mechanism cannot be neglected at the late stage. The fusion of vesicles is accompanied by translocation of chains from the outer monolayer to the inner monolayer. For mixed amphiphiles, the degree of segregation exhibits a size dependence of the vesicle. Compared to the chains with shorter hydrophilic blocks, those with longer hydrophilic blocks exhibit stronger trends to translocate from the outer monolayer to the inner one in vesicle self-adjustment, which leads to the quasi-equilibrium asymmetric distribution of the hydrophilic blocks in the post-fused vesicles

Evaluation of the reliability and validity of the health literacy scale for HPV vaccination among parents of girls aged 9–14

To evaluate the reliability and validity of the Health Literacy Scale for HPV Vaccination among parents of girls aged 9–14. A total of 830 parents of girls in grades 3–8 were sampled using convenience sampling in March-April 2024 in a school in a district of Shanghai, China, and item analysis was conducted using the critical ratio method, the correlation coefficient method, and Cronbach’s alpha coefficients; Cronbach’s alpha coefficients, Spearman-Brown split-half coefficients, and re-test reliability correlation coefficients were used for reliability evaluation, and content validity and validity factor analysis for validity testing. The scale was analyzed by item analysis to remove one indicator: “Whether a doctor’s advice affects vaccination,” and the final version of the scale consisted of 34 items divided into three dimensions: medical services (11 items), disease prevention (15 items) and health promotion (8 items). The Cronbach’s alpha coefficients for the total scale, medical services, disease prevention dimension and health promotion dimension were 0.913, 0.848, 0.839 and 0.747, respectively; the split-half coefficients were 0.751, 0.743, 0.875 and 0.762; and the re-test reliability correlation coefficients were 0.794, 0.890, 0.785 and 0.837. Content validity was good, and the results of the validation factor analysis showed that the finalized scale model was an acceptable model fit (RMSEA = 0.041, GFI = 0.937, AGFI = 0.914. The reliability and validity of this scale is good and can be used as an assessment tool for HPV vaccine health literacy in this population

The branching angle effect on the properties of rigid dendrimers studied by Monte Carlo simulation

We studied the properties of rigid dendrimers with different branching angles by means of Monte Carlo simulations on a coarse-grained level. It was found that the terminal groups of dendrimers with both rigid and flexible spacers could locate near the center of the molecule. In flexible dendrimers, the wide distribution is attributed to the back folding of flexible spacers, while in rigid dendrimers, it is caused by the branching angle effect that a branch will grow laterally due to the restriction of a non-zero branching angle. It has been established that the branching angle is a key parameter for rigid dendrimers, which can be applied to tune the properties of rigid dendrimers: decreasing branching angle is helpful to obtain dendrimers with a larger size, lower density, and more terminal groups locating at periphery.This work was supported by the Natural Science Foundation of China (No. 21464004); the State Key Laboratory Cultivation Base for the Chemistry and Molecular Engineering of Medicinal Resources (Nos.
