Voting with Time Commitment for Decentralized Governance: Bond Voting as a Sybil-Resistant Mechanism
Authors: Mohan Vijay , Khezr Peyman , Berg Chris
Published: March 2024

In this paper, we examine the usefulness of time commitment as a voting resource for decentralized governance when the identity of voters cannot be verified. In order to do so, we take a closer look at two issues that confront token-based voting systems used by blockchain communities and organizations: voter fraud through the creation of multiple identities (Sybil attack) and concentration of voting power in the hands of the wealthy (plutocracy). Our contribution is threefold: first, we lay analytical foundations for the formal modeling of the necessary and sufficient conditions for a voting system to be resistant to a Sybil attack; second, we show that tokens as the only instrument for weighting votes cannot simultaneously achieve resistance to both Sybil attacks and a plutocracy in the voting process; and third, we design a voting mechanism, bond voting, that is Sybil resistant and offers a second instrument (time commitment) that is effective for countering plutocracy when large token holders also have a relatively high opportunity cost of locking tokens for a vote. Overall, our paper emphasizes the importance of time-based suffrage in decentralized governance.

Retail Category Management with Slotting Fees
Authors: Alan Yasin , Kurtuluş Mümin , Nakkas Alper
Published: March 2024

Problem definition: Slotting fees are lump-sum payments retailers demand from manufacturers to include manufacturers’ products in their assortments. Although retailers regard slotting fees as part of doing business, some manufacturers claim that slotting fees limit their ability to compete on a level playing field with other manufacturers. Considering these conflicting views, we study the role of manufacturer competition in the emergence of slotting fees and how slotting fees affect retailers’ category management (i.e., assortment and pricing) decisions. Methodology/results: We consider a game-theoretic model with a single retailer and two competing manufacturers, each offering a single product. The retailer makes slotting fee, assortment, and pricing decisions in the presence of an operational cost term that increases in the assortment size. The manufacturers that can afford the slotting fee set the wholesale prices for their products. This study leads to three key findings. First, slotting fees can be suboptimal when their absence would trigger intense wholesale price competition. Second, depending on the retailer’s operational cost and the intensity of manufacturer competition, slotting fees create three distinct effects -category expansion, rent extraction, and competitive exclusion under which product variety (i.e., the retailer’s assortment size) increases, remains unchanged, and decreases, respectively. Third, slotting fees are most (least) beneficial for the retailer when they lead to a decrease (increase) in product variety. Managerial implications: This study not only illustrates that retailers can use slotting fees as a strategic tool to control the intensity of manufacturer competition but also reveals how slotting fees impact retailers’ assortment and pricing decisions, with implications for manufacturers and policy makers.

Doukhobors (Spirit Wrestlers) and Colonialism in Canada
Authors: Makarova Veronika
Published: March 2024

Abstract: Colonialism can be seen as a historical process, or an ideology. As this article demonstrates, for Canadian Doukhobors, it is also a lived experience. Canadian Doukhobors, or Spirit Wrestlers, are a group of pacifist religious dissenters of mixed ethnic origins who immigrated to Canada from the Russian Empire in 1899. The worldview of the Doukhobors was radically different from the principles on which the colonial government was founded. The goal of this article is to describe the colonial policies directed towards the Doukhobors, their anticolonial struggles, and to consider the implications of the Doukhobor history for contemporary anti-colonial thought in Canada and worldwide. The government subjected Doukhobors to a range of discriminatory actions including cancellation of earlier granted land registries in Saskatchewan, incarcerations for refusal of military service (despite an existing legal exemption), taking away children of some Doukhobors and placing them in a juvenile detention center to force the assimilation. While considering the significance of the Doukhobor struggles against colonialism, the article proposes a new term, 'colonial privilege.' This article is reflexive and sheds a new light on the earlier recorded facts. Résumé: Le colonialisme peut être considéré comme un processus historique ou une idéologie. Comme le démontre cet article, pour les Doukhobors canadiens, il s'agit également d'une expérience vécue. Les Doukhobors canadiens, ou lutteurs spirituels, sont un groupe de dissidents religieux pacifistes d'origines ethniques diverses qui ont immigré au Canada en provenance de l'Empire russe en 1899. La vision du monde des Doukhobors était radicalement différente des principes sur lesquels le gouvernement colonial était fondé. L'objectif de cet article est de décrire les politiques coloniales menées à l'encontre des Doukhobors, leurs luttes anticoloniales et d'examiner les implications de l'histoire des Doukhobors pour la pensée anticoloniale contemporaine au Canada et dans le monde. Le gouvernement a soumis les Doukhobors à toute une série d'actions discriminatoires, notamment l'annulation de l'enregistrement des terres octroyées antérieurement en Saskatchewan, l'incarcération pour refus du service militaire (malgré une exemption légale existante), l'enlèvement des enfants de certains Doukhobors et leur placement dans un centre de détention pour mineurs afin de les forcer à s'assimiler. Tout en considérant l'importance des luttes des Doukhobors contre le colonialisme, l'article propose un nouveau terme, celui de "privilège colonial" . Cet article est réflexif et jette une nouvelle lumière sur les faits précédemment répertoriés.
A Matter of National Dignity: Protection of Slaves and Southern Refugees in Canada, 1844–1869
Authors: Sevgur Serperi , Tastsoglou Evangelia , Kwon Eugena
Published: March 2024

Abstract: Canada's humanitarian tradition has been a pole of attraction to new immigrants and refugees and a source of pride for Canadians. As part of an ongoing research project on changing representations of refugees and immigrants in Canadian mainstream newspapers, this research note focuses on two groups of refugees who came to Canada around the time of the American Civil War. We discovered the two historical extradition court cases of refugees who were wanted by the US over allegations of criminality, by thematically analyzing Globe and Mail articles between the years of 1844-1869. Our analysis shows that the dominant ideological and thematic frame of refugee newspaper reporting at the time revolved around what Canada stood for, in terms of values, and who the Canadians were. Even though these two groups of refugees were represented differently, the issue of "the right to asylum" was never questioned and always deemed to be a manifestation of a putative, pre-confederation "Canadian" identity – which itself, in the newspaper discourse, rested on freedom, humanitarianism and the rule of law. We conclude this research note with contemporary reflections on our findings. Résumé: La tradition humanitaire du Canada a été un pôle d'attraction pour les nouveaux immigrants et les réfugiés et une source de fierté pour les Canadiens. Dans le cadre d'un projet de recherche en cours sur l'évolution des représentations des réfugiés et des immigrants dans les journaux grand public canadiens, cette note de recherche se concentre sur deux groupes de réfugiés qui sont arrivés au Canada à l'époque de la guerre civile américaine. Nous avons découvert les deux cas historiques d'extradition de réfugiés recherchés par les États-Unis pour des allégations de criminalité, en analysant thématiquement les articles de Globe and Mail entre les années 1844 et 1869. Notre analyse montre que le cadre idéologique et thématique dominant des reportages sur les réfugiés dans les journaux de l'époque tournait autour de ce que le Canada représentait, en termes de valeurs, et de l'identité des Canadiens. Même si ces deux groupes de réfugiés sont représentés différemment, la question du " droit d'asile " n'est jamais remise en question et est toujours considérée comme une manifestation d'une identité " canadienne " présumée, antérieure à la Confédération–qui elle-même est, dans le discours des journaux, non seulement un élément important de l'identité canadienne, mais reposait aussi sur la liberté, l'humanitarisme et l'État de droit. Nous concluons cette note de recherche par des réflexions contemporaines sur nos résultats.
An Integrated Theory of Happiness: The Yang Zhu Chapter of the Liezi
Authors: Joshi Devin
Published: March 2024

Abstract: This article examines the integrated approach to theorizing happiness in the Yang Zhu chapter of the book associated with the Daoist master Liezi. While ancient critics famously denounced Yang Zhu as an amoral, pleasure-seeking hedonist, I argue the Yang Zhu chapter offers an individually rational but socially non-conformist approach to well-being of considerable relevance to contemporary scholarship on happiness. Not only does the chapter offer an intriguing and counter-intuitive argument about what constitutes and causes well-being, but its philosophical implications address a large number of inescapably foundational conceptual questions that can serve as metrics for evaluating theories of happiness in general. These questions include the scope of happiness (i.e. who?, what?, when?, where?, how much?) causation (i.e. how?, why?), and purpose (i.e. why should it matter?) while also addressing possible tensions between subjective and objective experiences, uniform and diverse causality, individual and collective outcomes, relative vs. absolute happiness, and immediate vs. lasting fulfillment.
The Dao of Dialogue: Daoism, Psychology, and Psychotherapy
Authors: Cohen Elliot
Published: March 2024

Abstract: From analytical psychologist Carl Jung's exploration of internal alchemy through humanistic psychologist Abraham Maslow's plea for a more Taoistic Science to pioneering person-centered therapist Carl Rogers's embrace of nonaction, Daoist teachings have played a consistent, subtle but significant part in shaping popular approaches in psychology and psychotherapy. Contemporary cognitive therapies are increasingly informed by Daoist principles and cultivation practices—including the emergence of Chinese Taoist Cognitive Psychotherapy. In this paper, I outline the past, present and future of this cross-cultural dialogue, in addition to reflecting on my own Daoist encounters and inspirations that have led to my pursuit of more transpersonal and ecological approaches and insights. Our current global predicament is largely the result of a prevalent, insidious, largely unquestioned anthropocentric mindset, which reduces the natural world to natural resources. It is my firm conviction that a more Daoist-based worldview may prove to be a potent antidote to this detrimental, default way of thinking and more vital than ever when faced with impending climate crises and catastrophe—bridging the psychological, ecological and soteriological.
By Name and by Nature: Two Stories of People Named Unattractive in Daoist and Rabbinic Literature
Authors: Amihay Aryeh , Li Lupeng
Published: March 2024

Abstract: As part of a growing interest in comparing ancient Chinese and Jewish texts, this article examines two stories that share a theme of an unattractive person who is named according to their appearance. The Daoist story in the Zhuangzi describes Uglyface Tuo whose hideous looks did not deter women from adoring him and rulers admiring him for his administrative skill. A rabbinic story from the Babylonian Talmud ( b . Nedarim 66b) recounts the story of a homely wife whose husband compelled her to show something pretty about her to a rabbi. Zhuangzi's story thwarts any expectations for correlation between external appearances and internal substance, while the name continues to suggest a correlation between a label and content, defying a single approach. Within the Daoist tradition, and especially in Zhuangzi's thought, this seems to be the point, arguing against epistemic certainty. In the strikingly different Talmudic story, the aptly named person is a woman whose features do not elicit attraction. The correlation of her name and her appearance remains the defining similarity between the narratives. It is this consistency that holds the key to the narrative's resolution: her apposite name holds the power to restore order in the world, an order which her ugliness seems to threaten. The comparison between the two stories allows to enhance their contradictory lessons. The essay concludes by highlighting the benefits of cross-cultural research between these distant fields of study.
Before their very eyes: Enhancing the (pre)literacy skills of deaf children
Authors: Curran Melissa , Mirus Gene , Napoli Donna Jo
Published: March 2024

The challenge of supporting literacy among deaf children is as much linguistic as educational,
since a major stumbling block can be the lack of a firm first language foundation. It is critical to
meet this challenge, given the range of serious negative correlates to illiteracy. Students on the
campuses of Gallaudet University and Swarthmore College collaborate to address this issue in an
inter-institutional course in which we make bimodal-bilingual videobooks designed for enjoyable
shared reading activities between deaf children and their caretakers. These videobooks bring a
good signing model into the home and help develop a range of essential preliteracy skills.

Published: March 2024

Background

To Frailty is associated with postoperative delirium (POD) but is rarely assessed in patients undergoing noncardiac surgery. In this study, the correlation between preoperative frailty and POD, one-year mortality will be investigated in noncardiac Chinese geriatric surgery patients.

Methods

This study is a prospective, observational, cohort study conducted at a single center with Chinese geriatric patients. Patients who undergo noncardiac surgery and are older than 70 years will be included. A total of 536 noncardiac surgery patients will be recruited from the First Affiliated Hospital of Shandong First Medical University for this study. The Barthel Index (BI) rating will be used to assess the patient’s ability to carry out everyday activities on the 1st preoperative day. The modified frailty index (mFI) will be used to assess frailty. Patients in the nonfrailty group will have an mFI < 0.21, and patients in the frailty group will have an mFI ≥ 0.21. The primary outcome is the incidence of POD. Three-Minute Diagnostic Interview for CAM-defined Delirium (3D-CAM) will be conducted twice daily during the 1st-7th postoperative days, or just before discharge. The secondary outcomes will include one-year mortality, in-hospital cardiopulmonary events, infections, acute renal injury, and cerebrovascular events.

Discussion

This study will clarify the correlation of preoperative frailty with POD and one-year all-cause mortality in Chinese geriatric patients undergoing noncardiac surgery. Can preoperative frailty predict POD or one-year mortality? In the face of China’s serious aging social problems, this result may have important clinical value for the surgical treatment of geriatric patients.

InH.pyloriinfection, antibiotic-resistance is one of the most common causes of treatment failure. Bacterial metabolic activities, such as energy production, bacterial growth, cell wall construction, and cell-cell communication, all play important roles in antimicrobial resistance mechanisms. Identification of microbial metabolites may result in the discovery of novel antimicrobial therapeutic targets and treatments. The purpose of this work is to assessH.pylorimetabolomic reprogramming in order to reveal the underlying mechanisms associated with the development of clarithromycin resistance. Previously, fourH.pyloriisolates were induced to become resistant to clarithromycinin vitroby incrementally increasing the concentrations of clarithromycin. Bacterial metabolites were extracted using the Bligh and Dyer technique and analyzed using metabolomic fingerprinting based on Liquid Chromatography Quadrupole Time-of-Flight Mass Spectrometry (LC-Q-ToF-MS). The data was processed and analyzed using the MassHunter Qualitative Analysis and Mass Profiler Professional software. In parental sensitivity (S), breakpoint isolates (B), and induced resistance isolates (R)H.pyloriisolates, 982 metabolites were found. Furthermore, based on accurate mass, isotope ratios, abundances, and spacing, 292 metabolites matched the metabolites in the Agilent METLIN precise Mass-Personal Metabolite Database and Library (AM-PCDL). Several metabolites associated with bacterial virulence, pathogenicity, survival, and proliferation (L-leucine, Pyridoxone [Vitamine B6], D-Mannitol, Sphingolipids, Indoleacrylic acid, Dulcitol, and D-Proline) were found to be elevated in generated resistantH.pyloriisolates when compared to parental sensitive isolates. The elevated metabolites could be part of antibiotics resistance mechanisms. Understanding the fundamental metabolome changes in the course of progressing from clarithromycin-sensitive to breakpoint to resistant inH.pyloriclinical isolates may be a promising strategy for discovering novel alternatives therapeutic targets.
Determinants of public health expenditure in the EU
Authors: Piscopo Joseph , Groot Wim , Pavlova Milena
Published: March 2024

Background

Public health expenditure is one of the fastest-growing spending items in EU member states. As the population ages and wealth increases, governments allocate more resources to their health systems. In view of this, the aim of this study is to identify the key determinants of public health expenditure in the EU member states.

Methods

This study is based on macro-level EU panel data covering the period from 2000 to 2018. The association between explanatory variables and public health expenditure is analyzed by applying both static and dynamic econometric modeling.

Results

Although GDP and out-of-pocket health expenditure are identified as the key drivers of public health expenditure, there are other variables, such as health system characteristics, with a statistically significant association with expenditure. Other variables, such as election year and the level of public debt, result to exert only a modest influence on the level of public health expenditure. Results also indicate that the aging of the population, political ideologies of governments and citizens’ expectations, appear to be statistically insignificant.

Conclusion

Since increases in public health expenditure in EU member states are mainly triggered by GDP increases, it is expected that differences in PHE per capita across member states will persist and, consequently, making it more difficult to attain the health equity sustainable development goal. Thus, measures to reduce EU economic inequalities, will ultimately result in reducing disparities in public health expenditures across member states.

Authors: Murnak Raina
Published: March 2024

This article will explain the philosophy and methodology behind developing and teaching the performance artistry curriculum at the Frost School of Music at the University of Miami. Students who study performance artistry are more prepared to work in the popular music industry/marketplace – personally, artistically and professionally. They report being more widely informed about the business of their artistry, having clearer goals, owning their identities, embracing communication with their audiences, using a more honest voice on their social platforms, and feeling freer to take risks. Success in this field is a combination of presentation, forethought, execution, content, strategy and effectiveness on top of talent. I will detail performance artistry assignments and illustrate their role in bringing out authenticity and excellence in a collegiate music major population. This curriculum contains valuable training tools in different educational configurations (lecture-style classes, private instruction and workshop/masterclass settings) and all genres.

Authors: Kinasih Dwi Dewisri , Nurmasari Nuraini Desty , Prayogi Joni
Published: March 2024

In the wake of the recent global pandemic, COVID-19, companies need to maintain performance and manage firm risk. Companies should understand what can affect the firm's risk. This paper investigates the impact of board diversity and derivatives use on firm risk. The sample consists of 35 Indonesian LQ45 listed on the Indonesia Stock Exchange with an observation period of 2016–2020. The company's risk is proxied by the standard deviation of stock returns. This study uses a panel data regression model, namely fixed effect regression and random effect regression. The results of this study indicate that female board directorship is negatively associated with firm risk. It shows the significant role of female board directors in the company's board. Meanwhile, the use of derivatives has no significant effect on the firm risk. These results impact the development of literature that examines the influence of board diversity and the use of derivatives for hedging in Indonesia so that companies can determine company policies to reduce risk.

»Non è altro lo edificare se none un piacere uolunptario …«
Authors: Lörincz Simina Anamaria
Published: March 2024

In a time concerned with the emancipation of architecture from the mechanical arts to the liberal ones, Filarete challenged the mainstream rational-objective approach by proposing a poietic definition of architecture which spanned beyond craft and science. »Non è altro lo edificare se none un piacere volunptario…« is not yet another account of architecture, but it has become its supreme definition, possessing an almost universal value and demonstrating a vision ahead of its time. This paper investigates the multiple facets of this definition by situating it in the context of Renaissance architectural practice and within the framework of Filarete’s architectural treatise. Humanistic to the core, this definition transcends the usual anthropomorphic perspective on architecture (regarding the proportions, styles or expressions derived from the human body) and goes beyond the rational-material approach, addressing the sphere of sensitivity or even the realm of the spiritual. For Filarete, architectural creation is a true poietic act, consecrated to symbolism and emotion, while genuinely rooted in its manual, material dimension.
Fritz Beblo und das Straßburger Hochbauamt 1903–1918
Authors: Möllmer Tobias
Published: March 2024

Based on his unpublished memoirs, this essay describes the university and practical training of Fritz Beblo (1872–1947), who was in charge of the Building department of Strasbourg from 1903 to 1918. Beblo was a student of the architecture teacher Carl Schäfer in Karlsruhe, who was the starting point of a wide-ranging network of architects: the Schäfer students formed a sworn fraternity and supported each other in their professional advancement. Thus, out of loyalty to his teacher and his fraternity, Beblo only hired employees who had studied under Schäfer. In this way, he simultaneously guaranteed a uniform artistic understanding in his team and was able to let his employees work on the individual building projects independently. In this way, a considerable body of high-quality buildings in regionalist-reductionist forms was created, which became exemplary for public and private architecture in Alsace until the interwar period.
Optical-related properties and characterization of some textile fibers using near-infrared spectroscopy
Authors: Almetwally Alsaid Ahmed , Elfowaty Heba M.
Published: March 2024

When light falls on the fiber surface, it is absorbed, reflected, or refracted. These three phases of incident light determine, to a great extent, the behavior of lustre of major textile fibers. This article sheds light upon the behavior of some textile fibers, namely, polyethylene terephthalate, cotton, viscose, bamboo, tencel, and modal fibers, in terms of their reflectance percentages in the ultraviolet regions. Also, the direct and indirect band-gap energies of the used textile fibers were also investigated. The findings of this study revealed the significant differences among these used textile fibers in relation to their optical properties. Also, the chemical composition of the used textile fibers was easily identified using near-infrared spectroscopy. Finally, the findings of this study revealed that the used textile fibers are considered good insulators.
Degradation of a mixture of 13 polycyclic aromatic hydrocarbons by commercial effective microorganisms

Published: March 2024

The study focused on the contribution of effective microorganisms (EM) and their consortia, used in commercial biological preparations and formulations for soil revitalization, to the degradation of a mixture of 13 polycyclic aromatic hydrocarbons (PAHs) commonly found in the soil environment. PAHs, diverse forms of which are present in the environment, never occur individually but always as a part of a chemical mixture. Therefore, the research presented in this article, focusing on the EM impact on the mixture of PAHs, reflects the conditions most similar to natural ones. On Day 35 of the experiment, PAH levels decreased by 75.5–95.5%. The highest PAHs degradation efficiency was achieved for fluorene, with a preparation containing eight bacteria strains from the Bacillus genus: B. coagulans, B. amyloliquefaciens, B. laterosporus, B. licheniformis, B. mucilaginosus, B. megaterium, B. polymyxa, and B. pumilus. All tested preparations containing bacterial consortia and a preparation with the yeast S. cerevisiae intensified the PAHs degradation more effectively than formulations including only the yeast Yarrowia lipolytica or a mixture of Debaryomyces hansenii and Bacillus. The designed and proposed research will contribute to the development of biotechnological methods – bioremediation by microorganisms that are safe for the human and environment health.

Assessment of potential resistance to moisture damage and fatigue cracks of asphalt mixture modified with ground granulated blast furnace slag
Authors: Jasim Enas N. , Joni Hasan H.
Published: March 2024

Fatigue and moisture damage have been recognized as the most prevalent problems on asphalt roads, necessitating large annual expenditures for road maintenance. Much industrial waste is added to bitumen paving to enhance its conventional quality while decreasing the negative impacts on the natural environment and increasing resistance to pavement distress. This research uses ground granulated blast furnace slag (GGBFS) to substitute conventional filler (Portland cement [PC]) in hot mix asphalt (HMA). To determine how the GGBFS affects the HMA's susceptibility to moisture and fatigue cracks, Marshall characteristics, tensile strength ratio (TSR), and index of retained strength (IRS) of the asphalt concrete were evaluated. HMA was prepared with different rates of GGBFS (0, 25, 50, 75, and 100%) instead of PC. The data support the usage of 50% GGBFS in asphalt pavements as a partial replacement of PC, which enhanced Marshal stability by 34.4%, reduced flow value by about 12.9%, and increased TSR and IRS by 11.1 and 14.54%, respectively. The fatigue resistance of the modified asphalt mix at the optimum rate was evaluated with the four-point bending beam test; the fatigue life (Nf) increased by 33.8% relative to the reference mixture. The results obtained from this research hold scientific value for researchers and method designers aiming to enhance the resistance of hot asphalt mixtures to moisture and cracking. Using waste materials as an alternative to PC contributes to cost reduction while mitigating the environmental damages associated with cement manufacturing. To summarize, this research highlights the significance of exploring sustainable options in the construction industry, emphasizing the importance of reducing costs, and minimizing environmental impacts.

Through the past few months, our world witnessed and is still suffering from several severe earthquakes in different places around the globe like Turkey, Syria, and Morocco. Therefore, the seismic activity domain grew the center of attention for researchers, engineers, and even regular people. The most significant topics in this field that must be taken into consideration are soil–structure interaction (SSI) and structure–soil–structure interaction (SSSI). The term SSI refers to the connection among structure, foundation, and soil while the term SSSI refers to the link among adjacent structures with the soil. Formerly, these subjects were not taken into account through the numerical and analytical methods utilized for the dynamic analysis of the seismic response of the structures (i.e., the effect of soil was ignored), and this matter led to disastrous costs that included loss of lives and properties. This article intends to offer an inclusive helpful knowledge of some significant factors that were not taken into consideration in the previous studies and can be utilized in the field of seismic analysis and design for minimizing the possible risks of earthquakes particularly the heavy ones by defining the SSSI behavior of adjacent structures due to these factors. To accomplish this goal, a sequence of seismic examinations via a shaking table system will be performed taking into consideration the impact of soil media. These tests will inspect the effect of the structure’s orientation and distance between them on the dynamic response of two close steel structures predicating on sand soil. The orientations selected here are of two types: the first one is parallel to direction of the earthquake wave and the second one is perpendicular to direction of the earthquake wave. Each orientation will contain three tests of three distances: close distance, medium distance, and far distance. Two novel small-scale multi-degrees of freedom steel models of three storeys are utilized in this study. Test results illustrated that the diversity of buildings orientation with distances has a significant effect on the SSSI behavior of the neighboring buildings. It is seen that the orientation perpendicular to the direction of the earthquake wave offered maximum impact on the dynamic responses at the far distance while the parallel orientation gave ultimate effect at the medium distance.

Poly(3,4-ethylenedioxythiophene) (PEDOT) is introduced on the surface of a metal–organic framework material by solvothermal method to prepare nanorods (TE@Zn-MOFs) with both flame retardant and thermoelectric properties. Data from cone calorimeter and TG-IR show that TE@Zn-MOFs effectively improves the flame retardant and smoke suppression properties of epoxy-based coatings. At a high TE@Zn-MOFs content of 10 wt%, the coating oxygen index increased from 18.2% to 29.0%, the total smoke release decreased from 25.26 to 22.60 m2, and the V-0 level was achieved in vertical combustion classification. Moreover, PEDOT enables epoxy-based coatings to output a certain current value at different heating temperatures (50–200°C). This work demonstrates that MOFs with flexible and variable structures can serve as effective flame retardants for epoxy-based coatings and endow coatings with fire warning characteristics, providing a way to develop multifunctional coatings for different application scenarios.

Published: March 2024

Highly stretchable thermochromic wrapped yarns, which employ elastane filament (EF) as core, stainless steel wire, and thermochromic polyester filament as the first and second winding, was prepared, and the effect of elastane draft upon yarn properties was investigated. It was found that the elastane draft played an essential role in determining the final yarn behavior, and the optimized elastane draft parameter was 2.5 using Technique for Order Preference by Similarity to Ideal Solution. It is a distinctive configuration of yarn’s constituents and the EF draft that are responsible for the exceptional stretchability of yarns, and it showed mechanical robustness following cyclic stretch. Importantly, the yarn exhibited rapid, durable, and reversible color conversion when subjected to cyclic voltage, cyclic abrasion, and alkali. Finally, a flower-shaped pattern was fabricated by embroidering yarn onto an elastic substrate as a proof-of-concept, and no obvious variation of color fidelity was observed during the stretch.

The seismically active Ka-Ping Block within Xinjiang, China, represents a zone of potential earthquake hazards, and existing surface measurements cannot fully reflect the area’s sub-surface slip rates. To determine these slip rates and characterize the level of hazard that the study area may face in future years, using a cross-correlation of waveforms, we identified 432 repeat sequences along large faults (F1–F5) in the Ka-Ping Block between September 2009 and April 2022 and computed the annual slip rate for every sequence with the empirical relationship of the moment and the seismic magnitude. Spatial distribution images and temporal evolution characteristics of deep deformation in fault zones were constructed. We obtained five asperities in the Ka-Ping Block, the western portion of the PiQiang fault (F4) had a larger yearly slide rate than its eastern portion, and the southwest and eastern areas of the KEP station show an elevated risk of seismic activity within the next two years.

Objectives

Various techniques of closure of surgical incisions have been described ranging from various suture materials, staples and tapes to adhesive compounds. Cyanoacrylate is an adhesive compound available for surgical incision closure. Although sutures have been the preferred universal choice for surgical incision closure, glue is gaining popularity in specific places like pediatric injuries, facial injuries, laparoscopic incision closure, etc. This study aimed to compare the results between the application of cyanoacrylate and conventional suturing.

Methods

In this randomized control study, patients were divided into two groups of 100 each. The surgical incisions were closed using cyanoacrylate glue in Group A patients and polyamide (EthilonTM 2-0) in Group B patients. Post-operative pain was assessed using Visual Analogue Scale on the first, third, and seventh day. The wounds were evaluated for complications on post-op days 1, 3, 7, and 30 using the ASEPSIS score. Cosmetic outcome was assessed at the end of first month using the Modified Hollander Cosmesis Scale.

Results

Post-operative pain was significantly less in the glue group on days 1, 3, and 7. Wound infection with dehiscence occurred in 4 cases (4 %) in Group A and one patient (1 %) in Group B, which was statistically insignificant. There was no significant difference in cosmetic outcomes in either Group.

Conclusions

Cyanoacrylate is a good alternative to sutures in skin closure of clean and clean-contaminated surgical wounds.

In response to the limitations of the existing online learning system regarding the efficiency and accuracy of the question-and-answer (Q&A) teacher recommendation method, this research develops a Q&A teacher recommendation model utilizing a Graph Convolutional Neural Network. First, a time-sensitive online learning Q&A teacher recommendation model (A Time Sensitive Online Learning Q&A Teacher Recommendation Model; TSRM) is proposed to address the shortcomings that current recommendation methods ignore, i.e., the teacher’s ability to answer questions with time changes. Then, a TSRM based on Short and Long Term Interest for Answering Questions (LSTR) is proposed to address the problem that the current recommendation methods ignore, i.e., the types of questions of student users’ concerns can change. Finally, we combine the TSRM model and LSTR model to build an intelligent recommendation model for answering teachers. The conclusion is that the accuracy rate of TSRM model on the test set is 99.5%, and the recommendation success rate of LSTR model reaches 98.4%, which are better than the other two models. The above results can show that the LSTR model and TSRM model constructed by the study have high performance and can effectively perform the recommendation of answering teachers in the online learning system, thus improving the efficiency of solving students’ problem, improving students’ learning effect, and contributing to the development of university education informatization.
