In this research study, we have synthesized the bio-capped ZnO/g-C_(3)N_(4) nanocomposites by employing lemon juice(Citrus limon) as a stabilizer and mediator. Fruitfully, lemon juice which contains various acidic functional groups and citric acid has the capability to block the surface of g-C_(3)N_(4) from chemical reactivity and activated the surface of g-C_(3)N_(4) for various reactions. Consequently, the agglomeration behavior and controlled shape of g-C_(3)N_(4) has also been achieved. Our experimental results i.e. XRD,TEM, HRTEM, PL, FS, XPS, and PEC have confirmed that the lemon juice mediated and green g-C_(3)N_(4)(L-CN) have good performances and remarkable visible light photocatalytic activities as compared to the chemically synthesized g-C_(3)N_(4)(CN). Furthermore, the small surface area and low charge separation of g-C_(3)N_(4) is upgraded by coupling with Zn O nanoparticles. It is proved that the coupling of Zn O worked as a facilitator and photoelectron modulator to enhance the charge separation of g-C_(3)N_(4). Compared to pristine lemon-mediated green g-C_(3)N_(4)(L-CN), the most active sample 5Zn O/L-CN showed ~ 5-fold improvement in activities for ciprofloxacin(CIP) and methylene blue(MB) degradation. More specifically,the mineralization process and degradation pathways, and the mineralization process of ciprofloxacin(CIP) and methylene blue(MB) are suggested. Finally, our present novel research work will provide new access to synthesize the eco-friendly and bio-caped green g-C_(3)N_(4)nanomaterials and their employment for pollutants degradation and environmental purification. 展开更多

Legislatively,the people’s assessors are defined as individuals who share judicial power.However,in the context of dispute resolutions,their role is restricted by the courts,which affects the extent of their assessorial activities.It is imperative to reconsider the implications of the people’s assessors’deep involvement in mediation from the standpoint of societal division of labor.To enhance this division of labor,it is advisable that the people’s assessors relinquish their mediation roles.It is necessary to redefine the distinctions between people’s assessors,judges,and people’s mediators,including specially invited mediators.This would not only make up the deficiencies in the role of professional judges but also relieve the tension between judicial professionalism and popular accountability. 展开更多

This article explores the social transformation on account of surveillance conception preoccupied through the technology diffusion thanks to the Web 2.0 novel features.The new mediation abstracts the social provisions into radical customs of surveillance.It primes the supposition of socialization hitherto to transpire the scrutiny of the mutual rehearses of vertical and horizontal surveillance.Hence,the ultimate conversion keeps on through self-exposition notion in views of social interaction which so far posit the question of the privacy and public boundary owing to the hypothetical undue freedom of self-expression through Web 2.0.Thus,this paper examines the Surveillance Society in a comprehensive scope of the social structure vis-à-vis the ideas of generational submission towards social transformation.Using the dichotomy of digital revolutions,the Digital“Natives”are classified as typically addicted digital consumptions bearing the community outlooks,while Digital“Immigrants”persist in semi obedience along with the traditional adherence.Ultimately,the Panopticon conceptualizes the certainty of social surveillance by dint of proliferation of information flows keen on social conducts automated in both online and offline paths through technological appliances. 展开更多

Under the dual driven forces of soaring disputes and national policy,the dispute resolution ecosystem of China showed the mediation centralism,and the revival of mediation presented the characteristics of adversary system.In order to comply with the modern rule of law system,the traditional mediation is incorporated into the modern legal system through the three-level transformation of"discipline of laws","introduction of procedures"and"specialized cultivation",which was promoted by the popularity of social governance,the input of the idea of diversified solutions and the pragmatic impetus under the pressure of social transformation.The mediation movement has the characteristics of both consciousness of pragmatism and the initial legalization,but will also face the mediation disorder.The remodeling of mediation must be rooted in systematization and modernization.Its development trend includes expansion of fields,symbiosis of autonomy and specialization,and mandatory introduction. 展开更多

As promising anodes for sodium-ion batteries,metal sulfides ubiquitously suffer from low-rate and high-plateau issues,greatly hindering their application in full-cells.Herein,exemplifying carbon nanotubes(CNTs)-stringed metal sulfides superstructure(CSC)assembled by nano-dispersed SnS_(2) and CoS_(2) phases,cocktail mediation effect similar to that of high-entropy materials is initially studied in ether-based electrolyte to solve the challenges.The high nano-dispersity of metal sulfides in CSC anode underlies the cocktail-like mediation effect,enabling the circumvention of intrinsic drawbacks of different metal sulfides.By utilizing ether-based electrolyte,the reversibility of metal sulfides is greatly improved,sustaining a long-life effectivity of cocktail-like mediation.As such,CSC effectively overcomes low-rate flaw of SnS_(2) and highplateau demerit of CoS_(2),simultaneously realizes a high rate and a low plateau.In half-cells,CSC delivers an ultrahigh-rate capability of 327.6 mAh g^(−1) anode at 20 A g^(−1),far outperforming those of monometallic sulfides(SnS_(2),CoS_(2))and their mixtures.Compared with CoS_(2) phase and SnS_(2)/CoS_(2) mixture,CSC shows remarkably lowered average charge voltage up to ca.0.62 V.As-assembled CSC//Na1.5VPO4.8F0.7 full-cell shows a good rate capability(0.05~1.0 A g^(−1),120.3 mAh g^(−1) electrode at 0.05 A g^(−1))and a high average discharge voltage up to 2.57 V,comparable to full-cells with alloy-type anodes.Kinetics analysis verifies that the cocktail-like mediation effect largely boosts the charge transfer and ionic diffusion in CSC,compared with single phase and mixed phases.Further mechanism study reveals that alternative and complementary electrochemical processes between nano-dispersed SnS_(2) and CoS_(2) phases are responsible for the lowered charge voltage of CSC.This electrolyte/structure-dependent cocktail-like mediation effect effectively enhances the practicability of metal sulfide anodes,which will boost the development of high-rate/-voltage sodium-ion full batteries. 展开更多

Veterinarians today face an increased risk for malpractice claims in view of increased client awareness of the benefits of the human-animal bond and advances in preventive and specialized veterinary medicine.An important problem with medical malpractice litigation is the manner in which malpractice claims are resolved. In several countries, thousands of claims have been successfully resolved via Alternative Dispute Resolution processes such as mediation, conciliation and arbitration.In medical media-tion, health care providers, patients/animal owners, families, clergy and attorneys partici-pate directly in an informal, usually voluntary, dispute resolution process that can lead to for unique and promising approaches to resolving conflicts.Recently in Italy framework legislation addressing mediation has been introduced and it is also used to resolve medical malpractice disputes.Given that in Italy medical mediation is formally a new concept and is still evolving, an examination is made. The importance of “mediation” for veterinarians’ civil liability will be evaluated, underlining how it could become an important instrument in speeding up the resolution of court actions concerning medical mal-practice. 展开更多

Mediation is an important peaceful means of resolving international disputes.In such cases,the mediator invites member states in dispute to roundtable negotiations to bring about a reconciliation.In the late GCC crisis between Qatar on one hand and Saudi Arabia,UAE,Bahrain,and Egypt on the other,Kuwaiti mediation tries to bridge the gap and prevent escalation that might lead to military confrontation against Doha to force a change of regime.However,this mediation is always in danger of an elongated crisis that might worsen the situation and hinder the parties reaching a reconciliatory settlement of their dispute.This is a challenge that confronts the Kuwaiti mediator and jeopardizes the very existence of the GCC in case the Kuwaiti mediator fails to reach a settlement.The dispute went beyond a limited geographic one with Egypt joining the boycott and the symbolic presence of Turkish troops in Qatar.As such,the dispute has created an unprecedented political rift among Gulf States and their rulers and somehow worries the existing regimes.This worrying situation threatens the core principles of some of these States,including those who are still neutral towards the dispute. 展开更多

The Cameroonian daily press is now taking a new look at the use of photography in its columns. Photography is therefore at the heart of the new information system: the application of a new formula, a photographic formula, therefore visual, which is a novelty. The aim of our article is to highlight how the Cameroonian daily press constructs the discursive staging of this visual content. It proposes to examine the ways in which the news image in <i>Cameroon Tribune</i> is constituted in journalistic writing. In this article, we will analyse the photographic content of the daily newspaper <i>Cameroon Tribune</i>. The corpus consists of 1245 photographs from 25 issues published between 21 October and 22 November 2019. The technique used is media content analysis, which allows us to produce exhaustive descriptive statements that meet the criteria of scientific validity and reproducibility. Emancipated from its strict illustrative function, photography in the daily newspaper <i>Cameroon Tribune</i> then becomes fully a means of information and communication, in the same way as text. This translates into the construction of informative sets such as the importance of the surface area of the visual content which gives pride of place to the visual, giving an impression of abundance that is perceptible from the Front Page. One of the important features of the newspaper’s iconography is the great positivity of its images, which reinforces the closeness between the reader and the news. In total, the newspaper highlights photographs of limited informative interest: these are portraits that show the faces of the protagonists of the articles, to the detriment of current events. 展开更多

To explore the relationship between social support and sleep quality of community workers in Wuhan during the coronavirus disease 2019(the COVID-19 infection epidemic),this research constructed a mediating effect model to explore the mediating psychological mechanism of social support influencing sleep quality of front-line community workers.A total of 500 front-line community workers in Wuhan were investigated.We used the perceived social support scale(PSSS),the Connor-Davidson Resilience Scale(CD-RISC),the perceived stress scale(PSS),and the Pittsburgh sleep quality index(PSQI)to measure social support,psychological resilience,perceived stress and sleep quality.Specifically,the higher the PSQI,the worse the sleep quality.Pearson correlation structural equation model was used to analyze the relationship between these factors.The results showed that:(1)There was a significant negative correlation between social support,psychological resilience,and perceived stress of community workers and PSQI,that means,the higher the level of social support,psychological resilience,and perceived stress,the higher the sleep quality.(2)Social support positively predicted psychological resilience and perceived stress,and perceived stress negatively predicted PSQI.(3)Social support can affect sleep quality through the mediating role of psychological resilience and perceived stress,and the mediating role includes two paths:the single mediating role of perceived stress and the chain mediating role of psychological resilience-perceived stress.(4)Gender moderates the relation-ship between social support and perceived stress,and the influence of social support on perceived stress of women is higher than that of men.Gender moderates the relationship between psychological resilience and PSQI,and only women’s psychological resilience had a negatively predictive effect on PSQI,while men did not,which means that psychological resilience of female frontline community workers can positively predict sleep quality.This research reveals the relationship between social support and sleep quality and its mechanism and verifies that social support can indirectly affect physical health through psychological resilience and perceived stress.It provides reference suggestions and intervention guidance for improving the sleep quality of community workers. 展开更多

Background: Identifying correlates of physical activity that can be targeted as potential mediators is important for developing interventions to promote physical activity in adolescent girls. However, the mediated effects of multilevel correlates of physical activity remain poorly understood. Therefore, the present study aimed to examine direct and mediated effects of personal, social and perceived school physical environmental factors on school-based physical activity of Japanese adolescent girls. Methods: In this cross-sectional survey of the Japanese adolescent lifestyles, 344 junior high school girls were invited to complete self-report measures of age, grade, weight, height, self-efficacy, social support (family, friends and teachers), perceived school physical environment (equipment, facilities and safety) and physical activity at school (min per week during lunch time and after- school hours). Structural equation modeling analysis controlling for age was performed to examine the effects of body mass index (BMI), self-efficacy, social support and school physical environmental variables on lunchtime and after-hours physical activity. Results: The final structural model demonstrated an acceptable fit for each context-specific physical activity. During lunch recess, perceived equipment and friend support exhibited direct effects on physical activity;perceived facilities, safety, and self-efficacy were indirectly associated with physical activity through friend support. During after-school hours, both family and friend support directly affected physical activity at school;perceived safety, facilities and self-efficacy exhibited indirect effects on physical activity through family or friend support. However, there were no significant associations between equipment and after-school-hours physical activity. Regardless of contexts, BMI had neither direct nor indirect effects on physical activity. Conclusion: Social support from family and friends was identified as factors mediating the effects of perceived environment and self-efficacy on school-based physical activity among Japanese adolescent girls. This finding encourages the future development of effective interventions to promote physical activity through family and friend support in the future. 展开更多
