It has studied the type and number of sexualising features present in the videos that Spanish and British teenagers share on the social network TikTok, offering a comparative view. A total of 447 videos from 12 British and 12 Spanish tiktokers aged 11 to 17 have been analysed, considering their gender and age and comparing both nationalities. A high level of self-sexualisation has been found in the videos of adolescents of both genders and nationalities. The results show that age and gender determine the sexualising characteristics included in their videos and that British and Spanish minors do not use the same sexualising codes, although neither nationality is more sexualised than the other. It has been confirmed that boys and girls self-sexualise in similar proportions. Age determines sexualising characteristics they incorporate in their audio–visual productions, which indicate the blurring of traditional stereotyped roles and the unification of sexual codes that have traditionally been considered a female domain.","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"25 1","pages":"1262 - 1282"},"PeriodicalIF":11.7,"publicationDate":"2023-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73363320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The VBM shift follows precisely the behavior of the thermoelectric power factor, while the effective mass is barely modified upon changing the population of Sn vacancies.

In this paper, we focus specifically on how AI affects the communicative practices associated with creativity. AI has the capacity to reshape discipline and taste communities by providing new content that competes with human production and by mediating between human activity and information sources. To frame these issues, we turn to the influential systems model of creativity devised by Mihaly Csikszentmihalyi (1996), which Csikszentmihalyi and Daniel Gruner (2018) recently extended to incorporate AI, redubbing it Creativity 4.0. The model assesses how AI affects the social structure of creative practice without overly accentuating the similarity between humans and AI, or questioning whether computational devices will replace creative jobs. The paper examines Gruner and Csikszentmihalyi’s revised systems model, arguing that it does not sufficiently take into account the variety of ways that AI can be incorporated into creative practice. Prompted by a theoretical reflection on the nature of the model and the emerging features of AI, we propose a new version of the model that highlights how embedded AIs play a key role in filtering and gatekeeping, as well as the importance of generative systems in informing creative practice. We propose that any discussion of AI and the future of creative practice should look at where and how AI supported technologies are used. We examine how AI can reduce and shape the qualitative diversity of sources of inspiration drawn into the creative process, with the associated technological biases, as well as provide an emergent platform for the development of novel ideas.","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"58 1","pages":"1054 - 1069"},"PeriodicalIF":11.7,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74960687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the term ‘virtual’ may appear to be the opposite of ‘real,’ the boundary between virtuality and reality has become blurred due to the virtual embodiment being part of reality for participants. As VR and real virtuality converge, little is known about the ethical issues in producing computer-generated imagery (CGI) immersive journalism and the viewers’ responses to CGI VR news reporting. Our study applied a concurrent mixed-method approach, including in-depth interviews with eight CGI professionals from the U.K. and a quantitative survey in Taiwan, to understand the production issues, ethical concerns, and audience perceptions toward CGI immersive journalism. Results from the interviews suggested that digital journalists need to rethink their ethical codes, particularly the representation of truth while producing news stories using CGI images and VR. Findings from the post-test survey showed that both immersive presence and interactivity in VR news resulted in a greater formation of believing and motivations to take action regarding the topic presented in the VR news.","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"20 1","pages":"1033 - 1053"},"PeriodicalIF":11.7,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80708295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We reduce the tradeoff between light absorption and charge transport by combining a Fabry–Perot (FP) resonator and a distributed Bragg reflector (DBR). A FP resonance is formed between the DBR and a dielectric-metal-dielectric film as a top transparent electrode. A SiO<sub>2</sub>-TiO<sub>2</sub> multilayer is used to form a DBR. The FP resonance enhances light absorption near the resonant wavelength of the DBR without changing the CQD film thickness. The light absorption near the FP resonance wavelength is further boosted by coupling the FP resonance with the high reflectivity of the Ag-coated DBR. When the FP resonance and DBR are combined, the power conversion efficiency (PCE) of PbS CQD solar cells increases by 54%. Moreover, the DBR assisted FP resonance enables a very thin PbS layer to absorb near infrared light four times more. The overall PCE of the thin PbS CQD solar cell increases by 24% without sacrificing the average visible transmittance (AVT). Our results show how to overcome the inherence problem of the CQD and develop a semi-transparent solar cell where the wavelength-selective absorption and the transparency for visible light are important.</p></div>","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"10 1","pages":""},"PeriodicalIF":11.7,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://nanoconvergencejournal.springeropen.com/counter/pdf/10.1186/s40580-023-00379-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4168972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New Zealand’s media laws and regulatory bodies remain broadcast and legacy media-focussed, so podcast content that has not been previously broadcast is not regulated or otherwise overseen. In the absence of regulation, this study explores the ways nine independent podcast producers from New Zealand self-govern their content, as well as their motivations for doing so. It is an investigation of the ways ‘amateur’ content producers approach media ethics, and more broadly podcast production in practice. Not guided or bound by formal publishing or editorial responsibilities, and mostly with no formal media training, study participants demonstrate adherence to journalistic principles. They consider ethical and editorial quandaries as they arise during the production process, factoring in the needs and disposition of their audience. This process is informed by their worldview, as well as their perspectives and experiences as media consumers. Though these podcasters champion the ethos of independent podcasting, the content of their shows is not free from third party influence. These podcasters are also parents, partners, employees, and colleagues; life roles that inform the content of their show. Though they push back against podcasting being legislated, these podcasters see value in creating an informal set of guidelines or a voluntary code of practice for podcasting in New Zealand. This project contributes to ongoing explorations of independent podcasting and podcasting practice, focussing on what defines, motivates, and informs self-driven practitioners.","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"79 1","pages":"854 - 870"},"PeriodicalIF":11.7,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90923349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expansion of streaming services such as Twitch and YouTube Live played an important role in this leap and greatly contributed to the rise in popularity of electronic sports. Despite this success, there is no research on the topic of streaming demand of eSports to date. This paper aims to fill this gap using a demand approach of traditional sports to analyze the streaming demand of an eSports discipline, the Counter-Strike: Global Offensive. The dataset comprises 865 matches between 2018 and 2021. Multiple Linear Regressions are taken as econometric tools. Main findings indicate that eSports enthusiasts value factors such as quality of tournament, match quality, and individual skill of the athletes when watching matches. In addition, the obtained results reveal that the Uncertainty of Outcome plays a significant role at streaming broadcasts of Counter-Strike: Global Offensive, where viewers prefer to watch those games in which there is a high level of competitiveness between the participants. Current research contributes to the existing eSports literature with a new framework for analyzing streaming demand. The empirical findings could be of the interest of tournament organizers as well as streaming platforms for maximizing audiences.","PeriodicalId":712,"journal":{"name":"Nano Convergence","volume":"7 1","pages":"1369 - 1388"},"PeriodicalIF":11.7,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87710079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional ultrasound detectors using piezoelectric materials have been widely used for transducing ultrasound signals into the electrical signals for PA imaging reconstruction. However, their inherent limitations in detection bandwidth and sensitivity per unit area have unfortunately constrained the performance of PA imaging. Optical based ultrasound detection methods emerge to offer very promising solutions. In particular, polymer micro-ring resonators (MRRs) in the form of integrated photonic circuits (IPC) enable significant reduction for the sensing area to 80 μm in diameter, while maintaining highly sensitive ultrasound detection with noise equivalent pressure (NEP) of 0.49 Pa and a broad detection frequency range up to 250 MHz. The continued engineering innovation has further transformed MRRs to be transparent to the light and thus, opens up a wide range of applications, including multi-modality optical microscope with isometric resolution, PA endoscope, photoacoustic computed tomography (PACT), and more. This review article summarizes and discusses the evolution of polymer MRR design and the associated nanofabrication process for improving the performance of ultrasound detection.
