Development of fullerene acceptors and the application of non-fullerene acceptors in organic solar cells

Organic solar cells (OSCs) enjoy a huge market and public attention as an emerging renewable and clean energy source due to their accessibility, sustainability, translucency, good flexibility, non-toxicity, and low preparation cost. However, the choice of an acceptor material is now the pivotal factor restricting the development of OSCs. To continuously improve stability and increase power conversion efficiency (PCE) for better performance, high-performance acceptor materials are an important part of enabling OSCs. From fullerenes and their derivatives and non-fullerenes, we sum up the latest research progress on high-performance acceptor materials for OSCs and then introduce the synthesis methods of non-fullerenes. The latest strategies to enhance the performance of organic solar cells and the wide range of applications of non-fullerene acceptors (NFAs) on different OSCs are also discussed. In addition, challenges faced by OSCs in improving their performance and the prospects for future development are revealed, providing new ideas for designing the next generation of high-performance OSCs.

Seroprevalence of Infection by Borrelia Species Responsible for Lyme Disease in the French Alps: Analysis of 27,360 Serology Tests, 2015-2020.

Objectives: Lyme borreliosis incidence is increasing in several areas; moreover, it has recently gained the public's attention. Apart from erythema migrans, Lyme disease diagnosis relies (among others) on serology test; however, the prevalence of positive enzyme-linked immunosorbent assay (ELISA) and western blot (WB) assay has been poorly studied in the general population. We aimed to approach the seroprevalence of infection by Borrelia species responsible for Lyme disease in the French Isere department using city laboratories data. Patients and Methods: We retrieved all serological tests for Borrelia species responsible for Lyme disease performed in the two main networks of city laboratories between 2015 and 2020. All patients with both ELISA and WB IgG were considered seropositive. Results: We analyzed 27,360 tests (ELISA/ELISA+WB). Mean age was 50.9 ± 20.3 years (ranges: 0-101), with 57.1% females. Overall, 11.7% had IgG detected by ELISA, and 4.7% had IgG detected by both ELISA and WB assay. Seropositive status was more frequent in males (7.0% vs. 2.9%, p < 0.001). Seropositivity rate increased with age after a first peak in childhood; men aged 61-70 years had the highest seropositivity rate (10.3%). In addition, seropositivity rate was higher in persons from a rural area. In multivariate analysis, older age, male gender and living in a rural area were independently associated with seropositivity. Seropositivity rate was stable on the 2017-2020 period. Conclusion: The seroprevalence of infection by Borrelia species responsible for Lyme disease is high in Isere; this probably reduces the predictive positive value for Lyme disease of ELISA and WB IgG, suggesting that this serological test should not be performed for nonspecific symptoms.

Ecological ramifications of marine debris in mangrove ecosystems: Estimation of substrate coverage and physical effects of marine debris on mangrove ecosystem in Negombo Lagoon, Sri Lanka

The adverse environmental impacts on mangrove ecosystems due to anthropogenic marine debris contamination have attracted public attention not only in Sri Lanka but worldwide. Therefore, quantification of marine debris in sensitive ecosystems like mangroves is critical to assess the impacts on ecosystem vitality and services. We conducted this study to assess the abundance and density of marine debris in Negombo lagoon, Western Province, Sri Lanka. We selected two sites (n = 2) using the purposive sampling technique. Marine debris cover and concentration were calculated to explore the extent of pollution from marine debris. The findings revealed that 9.83 ± 1.05 % of the substrate of the mangrove ecosystem is covered by debris. Nine types of marine debris were recorded, and a higher abundance belonged to single-use plastic items. A significantly higher debris cover was found in Kadolkele (18.80 ± 1.74 %, n = 120) than in Molekadolwetiya (0.85 ± 0.03 %, n = 120) (One-way ANOVA, p < 0.05). The study indicated that the mangroves in lagoon are highly polluted with marine debris and act as “litter catchers.” Correlation coefficient analysis was used to find the impact of debris cover on physical damage to roots, seedlings, and undergrowth vegetation. Correlation analysis revealed that physical damage to seedlings and branches/barks have a positive correlation with debris cover. To conserve these valuable coastal habitats in Negombo lagoon, it is recommended to take remedial measures to reduce arriving debris loads and to remove the debris present in mangroves.

Effects of finance knowledge influencer qualities on investment willingness and the moderation of followers' risk tolerance

AbstractFueled by the rise of social media, internet celebrities (or influencers) are a subgroup of public figures who have gained extreme public attention in recent years. In this study, we examined the qualities of finance knowledge influencers to elucidate the impact that investment discussions or tutorials posted by influencers have on followers' and audiences' investment willingness. We adopted attractiveness, expertise, and trustworthiness as the independent variables, followers' risk tolerance as the moderator, and followers' investment willingness as the dependent variable. For data collection, respondents were instructed to watch three different influencer videos and complete a questionnaire. A total of 327 valid questionnaires were collected and analyzed. The questionnaire survey results showed that influencers' attractiveness expertise, and trustworthiness positively affected followers' investment willingness. Furthermore, followers' risk tolerance negatively moderates the relationship between influencer attractiveness and investment willingness, but it positively moderates the relationship between influencer trustworthiness and investment willingness. The empirical findings of this study theoretically contribute to academics and have practical implications in the real world. We propose several suggestions for future research.

Ex-Ante Flooding Damages’ Monetary Valuation Model for Productive and Environmental Resources

The floods caused by river flooding are increasingly at the center of public attention and government agencies. This is due to climate change, a higher risk consciousness of settled populations, as well as the deteriorating state of water basins caused by the persistent absence of appropriate controls on the use of mountain and hilly territories. In Italy, the risk of flooding is particularly high, posing a significant social problem due to the number of victims and the damage inflicted on properties, industries, and infrastructure. This paper aims to examine the principles and methods of evaluating the damage caused to the territory by river flooding. Two evaluation models are developed for the formal definition of the variation law of damage caused by flooding, considering the return period of the flood event. The first model allows the evaluation of damage to the productive part of the territory affected by floods, while the second considers damage related to the environmental aspects.

A Density Management Diagram for Pitch Pine to Illustrate Tradeoffs between Carbon and Wildfire Risk

Abstract Pitch pine (Pinus rigida Mill.) can be found across a broad range in eastern North America but assumes local dominance only on poor soils in the northeastern United States. Contemporary management goals in the Northeast for areas dominated by pitch pine are focused on noncommercial benefits of forests, such as carbon density, reduced wildfire risk, habitat for rare species, and water provisioning. We present a density management diagram that empirically articulates the size-density limits of even-aged pitch pine stands. Included in the diagram are wildfire risk and carbon density, which are inversely related for most stand sizes. Maximum possible aboveground live tree carbon begins to decline at a quadratic mean diameter greater than 9 in., while crown fire risk remains high along the size-density limit until a quadratic mean diameter above 12 in. is achieved. Study Implications: Modern silvicultural tools that illustrate forest stand conditions have not been developed for pitch pine, but this species occurs in a region with much public attention on forests. We develop and present a density management diagram to show the interplay of different social goals for the forest and how they relate to the maximum size-density relationship. Pitch pine stands with high levels of aboveground live carbon are at high risk of crown fire, particularly in the smaller size classes.

Private and public interests as factors in the effectiveness of public-private partnership

Cooperation carried out within the framework of public-private partnerships is characterized by high risks of dishonest behavior of the parties to the agreement. The circumstances that encourage dishonest behavior of the state and private partners are considered. The stages of implementation of public-private partnership projects have been established, at which the risk of dishonest behavior is the highest. Recommendations aimed at minimizing such risks are proposed. It is concluded that it is necessary to increase the transparency of ongoing procedures, expand the parameters taken into account and controlled when making decisions within the framework of public-private partnerships, the importance of detailed documentation of the facts of economic life and attract public attention to public-private partnerships.

BEYOND THE COVER: MARKETEERS MAGAZINE'S DIGITAL ADAPTATION THROUGH COMMODIFICATION

This research was motivated by the increasing number of online media that make it easier for people to access information quickly, causing a decrease in public interest in print journalism. As a result, many print media companies had to close. Marketeers magazine overcame this problem by making covers one of the primary weapons to attract public attention. Through this structural study, researchers analyzed how Marketeers magazine responded to these conditions with commodification made to content, readers, and workers. This research uses a critical model with a qualitative approach. This research method is a descriptive analysis and data collection method using in-depth interviews so that researchers can dig for more data and facts on critical informants and informants. The results of observations made with these interviews are compared between the results of interviews. The results found that Maketeers carried out a process of commodification of content, readers, and workers. From the commodification process, Marketeers magazine experienced an increase in sales. This can be a benchmark for print media industry entrepreneurs in Indonesia so that they can continue to exist in the Indonesian print media industry.

Conspiracy, misinformation, radicalisation: understanding the online pathway to indoctrination and opportunities for intervention

In response to the rise of various fringe movements in recent years, from anti-vaxxers to QAnon, there has been increased public and scholarly attention to misinformation and conspiracy theories and the online communities that produce them. However, efforts at understanding the radicalisation process largely focus on those who go on to commit violent crimes. This article draws on three waves of research exploring the experiences of individuals currently or formerly involved in fringe communities, including the different stages of investment they progressed through, and ultimately, what made people leave. We propose a pathway model for understanding contemporary online radicalisation, including potential interventions that could be safely made at each stage. Insight into the experience of being immersed in these communities is essential for engaging with these people empathetically, and therefore preventing both the emergence of violent terrorists and protecting vulnerable people from being drawn into these communities.

Public Diplomacy of Indonesia Towards Turkey Through The Youtube Platform Endonezya Evi

Globalization brings changes to all fields including the practice of state public diplomacy, changes occur in public diplomacy media that use social media, one of which is YouTube used by Indonesia through the Endonezya Evi Platform in Turkey, this change occurs because the use of conventional media previously used by Indonesia through the Indonesian Cultural House has shown a decline in Turkish public attention so that new media is needed that is more easily accepted by the Turkish public. Evi's Endonezya platform was deemed easier to access and did not require a large amount of money to run. &lt;The purpose of this article is to find out whether the Endonezya Evi Platform can be used in the practice of Indonesian public diplomacy in Turkey and how it impacts. &lt;The method used in this article is descriptive analysis by examining the Endonezya Evi Platform used by Indonesia. This article shows that the Endonezya Evi Platform is a new media that can be used in the practice of Indonesian public diplomacy because it can reach a large audience and does not require large costs and the Endonezya Evi Platform fulfills the components of public diplomacy so that it can be used as a tool in the practice of Indonesian public diplomacy in Turkey.

Diverse impacts of red palm olein, extra virgin coconut oil and extra virgin olive oil on cardiometabolic risk markers in individuals with central obesity: a randomised trial.

Dietary fats with an abundance of phytonutrients have garnered public attention beyond fatty acids per se. This study was set to investigate the impact of consuming diets with red palm olein (RPOO), extra virgin coconut oil (EVCO) and extra virgin olive oil (EVOO, as a control) on cardiometabolic risk biomarkers and lipid profile. We recruited a total of 156 individuals with central obesity, aged 25-45years, with waist circumference ≥ 90cm for men and ≥ 80cm for women in a parallel single-blind 3-arm randomised controlled trial. The participants consumed isocaloric diets (~ 2400kcal) enriched with respective test fats (RPOO, EVCO or EVOO) for a 12-week duration. The mean of the primary outcome plasma high sensitivity C-reactive protein was statistically similar between the three diets after a 12-week intervention. EVOO resulted in significantly lower mean LDL cholesterol compared with RPOO and EVCO, despite similar effects on LDL and HDL cholesterol subfractions. The RPOO diet group showed elevated mean [Formula: see text] and [Formula: see text]-carotenes levels compared with EVCO and EVOO diet groups (P < 0.05), corresponding with the rich carotenoid content in RPOO. The three oils, each of which has unique phytonutrient and fatty acid compositions, manifested statistically similar cardiometabolic effects in individuals with central obesity at risk of developing cardiovascular diseases with distinct circulating antioxidant properties.

The politics of accountability: violence, mass punishment and restorative justice

ABSTRACT Fifty years of rising incarceration and mass punishment have solidified the carceral state as central to US governance and culture, and entrenched the perception of punishment as the most effective and moral response to interpersonal violence. Today, within a growing discourse challenging punishment as the primary response to interpersonal violence, restorative justice (RJ) is the most commonly promoted alternative. Yet in the context of the criminal legal system and in the broader RJ ecosystem, RJ responses to violence are limited, receiving minimal public and academic attention. This paper traces the developments of mass punishment and RJ over the last 50 years, analyzing their contrasting political and social evolutions. This analysis illustrates how punishment has captured the political, legal and social possibilities as it relates to violence, and how and why the field of RJ has been limited in its ability to advance non-punitive accountability-based approaches to violence. In addition, lessons are drawn from these instructive histories for the growing RJ efforts to address violence, to consider and challenge the varying forces that have made growing these responses difficult.

Measuring the age-friendliness of streets' walking environment using multi-source big data: A case study in Shanghai, China

The rapidly aging population demands more public and academic attention to both the physical and psychological needs of older adults. Walking is one of the most favored forms of transportation and exercise for older adults. Hence, the conditions of walkways and the built environment are critical for the development of an older adults-friendly society. In this research, considering six indicators of greenness, walkability, safety, imageability, enclosure, and complexity, a novel quantitative evaluation model based on multi-source geospatial big datasets is proposed for assessing the age-friendliness of streets' walking environment from both the older adults' and experts' perspectives and has also been successfully applied in the case study of Xuhui District in Shanghai, China. Based on the survey with both groups of older adults and experts, the age-friendliness of the streets' walking environment from both perspectives was obtained, analyzed, and compared. The results show that among all sub-districts in Xuhui District, Tianping Road Sub-district and Hunan Road Sub-district have the best walking environment; and the roads surrounding expressways or arterial roads typically have lower levels of age-friendliness, while sub-arterial roads and access roads generally exhibit higher levels of age-friendliness according to both older adults and experts. It is also noted that streets with high age-friendliness for older adults tend to be outstanding in walkability and greenness, whereas experts prefer streets with high safety and walkability. In addition, the comprehensive analysis of the impact factors on age-friendliness further reveals a series of hidden significant influencing factors associated with the different preferences between older adults and experts. It is believed that our findings are useful for supporting policy-makers on how to improve the age-friendliness of streets and build age-friendly cities.

Unveiling the trajectory of corporate green innovation: The roles of the public attention and government

In the ongoing pursuit of establishing a diversified environmental governance system, individuals, businesses, and various social groups are increasingly articulating their ecological demands in a conscious and organized manner. Recognizing the pivotal role of public attention (PA) in shaping business behavior is imperative for advancing a sustainable and environmentally friendly economy. Consequently, this study delves into the relationship between PA and corporate green innovation (CGI) by analyzing data from A-share industrial listed companies in Shanghai and Shenzhen spanning the years 2011–2020. The analysis employs fixed effects and a mediation model to provide a nuanced understanding of the dynamics involved. The study's findings underscore the following key points: (1) Elevated levels of public attention significantly influence CGI. (2) Government research and development (R&D) subsidies assume a regulatory role in the interplay between PA and CGI, particularly within state-owned enterprises, as well as the mining and manufacturing industries. However, it is noteworthy that an overly generous subsidy policy may inadvertently stifle corporate R&D innovation. (3) Government environmental regulations and corporate social responsibility indirectly shape the association between PA and corporate R&D innovation. Consequently, a fundamental strategy for fostering corporate green development lies in the effective management of government R&D subsidies and environmental regulations. Striking the right balance in these aspects while urging businesses to augment their sense of social responsibility is vital. This approach will pave the way for an efficient and enduring interaction system among the public, government, and companies, ultimately facilitating sustainable development and contributing to the realization of a beautiful China.

A Virtual Battlefield for Embassies: Longitudinal Network Analysis of Competing Mediated Public Diplomacy on Social Media

ABSTRACT Mediated public diplomacy is a critical way of strategic communication for governments to influence global public opinion, especially during international conflicts. Based on the theories of mediatization and digitalization as well as the layered model of communicative space, this study investigates how the United States and Iranian embassies competed on the Chinese social media platform Sina Weibo over 13 months. Following a network ethnography approach, this study conducts longitudinal network analysis and textual analysis. The findings suggest that the macro-layer function (i.e. hashtag) facilitated horizontal dissemination of news about the US-Iran conflict from mainly China’s state-media accounts, increasing public awareness of the issue within a short time. The meso-layer (repost and follower network) and micro-layer (mention and comment) functions helped establish vertical communication facilitated by opinion leaders and crowd-enabled leaders that perpetuated public attention on relevant issues. The two embassies engaged with the Chinese public in different communicative layers. The US embassy interacted with the Chinese publics through reposts and replies, while the Iranian embassy constructed their posts in the form of replies. The Iranian embassy leveraged China’s state media agendas as narrative agency to conduct diplomatic communication by incorporating relevant hashtags in their posts. A layered model of mediated public diplomacy is proposed. The findings deepen our understanding of competing mediated public diplomacy, and contribute to the field of international communication of international conflicts.

Strategi Pemasaran Politik Mohammad Idris-Imam Budi Hartono pada Pilkada Serentak Kota Depok Tahun 2020 di Era Pandemi Covid-19

The Covid-19 pandemic brought multi-sector changes in Indonesia not only in the fields of education and the economy, but also affected the democratic system in Indonesia in the implementation of the simultaneous Pilkada which was planned to be held in September 2020 postponed for up to 3 months. By continuing to carry out the Pilkada it was proven that the organizer, namely the KPU, issued regulations regarding campaigns during the Covid-19 pandemic so as not to trigger new clusters, which in the end made the candidates, including Idris-Imam, consider his marketing strategy so that he could win the contest that took place in Depok City. The aim of this paper is to describe the marketing strategy for the 2020 Depok Mayor and Deputy Mayor elections, this is interesting to review because of its implementation in the Covid-19 era. This study used a qualitative method whose analysis used descriptive data whose data were obtained from informants from the Idris-Imam winning team, members of the social media division and members of the winning team, while also using a number of articles or documents related to this paper. The results of this study indicate that the marketing strategy used by Idris-Imam follows the marketing concept of Nursal (2004): 1) Push Marketing, in marketing Idris-Imam interacts directly with the public from door to door by applying applicable rules, 2) Pull Marketing, the covid-19 pandemic is not an obstacle for Idris-Imam optimizes many social media platforms to disseminate its activities to gain public attention, 3) Pass Marketing, in marketing cooperates with religious figures and influencers to gain support to strengthen Idris-Imam reputation in public.

Can Green Infrastructure Investment Reduce Urban Carbon Emissions:Empirical Evidence from China

Green infrastructure (GI) plays a pivotal role in contemporary urban infrastructure. Green infrastructure investment (GII) provides a fresh perspective for controlling urban carbon emissions in the context of global climate change. Based on theoretical analysis, we employed panel data from Chinese cities to examine the effects and operating mechanisms of GII on urban carbon emissions. The research reveals that the incremental GII can notably decrease urban carbon emissions, and various robustness tests and endogeneity checks corroborate this finding. However, when considering the cumulative effect, the GII stocks do not appear to influence urban carbon emissions; GII mitigates urban carbon emissions by drawing in pollution control talents, improving the efficiency of household waste treatment, increasing urban green spaces, and heightening public attention to the environment. Relative to cities in the central-western region, northern cities, smaller cities, resource-based cities, smart pilot cities, and cities with a lesser environmental emphasis, GII is more effective in curbing carbon emissions in eastern cities, southern cities, larger cities, non-resource-intensive cities, cities not in the smart pilot initiative, and cities with a stronger environmental focus. This research enhances the understanding of GI’s environmental outcomes and the determinants of urban carbon emissions from an investment viewpoint. It also dissects the four operative mechanisms through which GII lowers urban carbon emissions, offering a novel interpretation of GII for the variance in carbon emission levels across cities with diverse traits.

Using photo editing to understand the impact of species aesthetics on support for conservation

Abstract Many threatened species suffer from a lack of conservation attention compared to others. Prioritisation of funding, research and conservation efforts seem to be driven by reasons beyond conservation need. This could be due to a ‘beauty bias’, whereby aesthetically pleasing species receive more attention. We examined how editing an image to increase a species' aesthetic appeal may impact donation choices and public attitude towards that species. We posed two research questions; first, ‘do people make different donation choices when they see original images of a species compared to when they see images of the same species that have been edited to match aesthetic preferences?’ Using hypothetical donation experiments, we asked respondents to allocate funds to the conservation of three pictured species, one ‘aesthetically appealing’, one ‘aesthetically unappealing’, and one whose image was either edited to reflect common aesthetic preferences or left unedited. Our findings suggest that images edited to make an animal more visually appealing tend to receive higher hypothetical donation amounts than original images. We also posed a second research question; ‘How do people of varying conservation expertise respond to original versus edited images of wildlife?’ To investigate this, we ran three focus groups with individuals unfamiliar with our test species, those familiar with two or more of our test species, and with conservation professionals, which showed mixed reactions both within and between groups. Focus group participants with less conservation expertise noted that edited images often seemed ‘cuter’ than unedited images, and were more likely to compare them to cartoon characters. Participants with more conservation expertise and species familiarity reported greater empathy towards unedited images, and noted that the edited images prompted an ‘uncanny valley’ response, highlighting the need for further scrutiny in how photo editing might be used in conservation messaging. Our findings support the beauty bias hypothesis and highlight that decisions on conservation support should acknowledge that less aesthetically pleasing species are disadvantaged in public attention and funding. In addition, the findings highlight the role of conservation expertise in impacting viewer reactions, as well as the ethical implications of editing images of wildlife.
