CIRCULATING CELL-FREE MESSENGER RNA BIOMARKERS FOR MINIMAL RESIDUAL DISEASE IN SOLID TUMORS
Authors: Yeh Chen
Published: June 2023

Tumor derived signals were amplified in cfmRNA due to increased expression of these markers in tumor tissue. The ability to measure MRD through the analysis of cfmRNA could lead to the amplification of cancer specific signal by orders of magnitude compared to mutation fraction alone. We now have a comprehensive picture ofthe types of plasma oncogenic cfmRNA andhave identified a class of cancer specific cfmRNA biomarkers in low noiseregions of the cell free transcriptome.Plasma cfmRNA can enable the MRD measurement of a variety of cancersbesides hematological malignancies to reduce cancer mortality. The MRD testing strategy can predict risk of recurrence more precisely, making it possible to reduce unnecessary therapy to improve quality of life for cancer patients.

Published: June 2023

Habitat manipulation by planting plants in the land or around crops is a way to increase the diversity of insects. The homogeneity of the agricultural landscapes leads to a decrease in insect biodiversity and ecosystem services. This study focuses on examining the diversity and ecological role of macro insects in chili pepper using barrier crops. We use mung beans, tomatoes, and eggplant as a barrier crops in the practice of cultivating chili pepper. The results showed that the use of barrier crops is not significant to increase the diversity of insects but the use of mung bean barrier can increase the number of species. Chili pepper land with mung bean barrier shows the abundance of predators, parasitoids, and pollinators higher than land without barrier crops. On land without barrier crops, the composition of herbivore insects tends to be lower when compared to land using barrier crops. The number of natural enemy individuals (predators and parasitoids) on land with mung bean barrier tend to be higher compared to without barrier crops. In the practice of chili pepper cultivation, it is necessary to utilize mung beans as a barrier for pest management strategy and increased production of chili pepper and also for conservation strategy of natural enemies

Published: June 2023

Winter pruning has been a common practice in peach. Twig topping has been associated with it, but this practice has been used at the same intensity, regardless of the cultivar. Therefore, this study aimed at evaluating productive behavior and quality of ‘Maciel’ peach grafted on ‘Capdeboscq’ and ‘Okinawa’ (P. persica) as rootstocks, when they were submitted to different twig topping intensities in winter pruning. The following three pruning intensities were evaluated: short pruning, when 2/3 of the productive twig was removed; long pruning, when 1/3 of the twig was removed; and pruning with no topping, when twigs were kept integral. Effective fructification is lower when ‘Maciel’ peach trees are submitted to short pruning, but it leads to fruit with higher weight and flesh firmness, besides larger diameters. Pruning with no twig topping and long pruning increased the fruit number and yield per tree. Not only fruit weight, diameter and soluble solid content, but also yield per tree of ‘Maciel’ peach are affected by ‘Capdeboscq’ and ‘Okinawa’, regardless of the intensity of twig topping throughout pruning. Higher concentration of soluble solids was found in peaches grafted in Okinawa. While the highest production was verified with the use of the ‘Capdeboscq’ rootstock.

A convivência com as plantas daninhas prejudica o acúmulo de nutrientes nas plantas de cenoura, porém, o mulch pode reduzir os efeitos da competição e proporcionar vantagens a cultura de interesse. Este trabalho objetivou avaliar o uso do mulch de palha de aveia-preta (Avena strigosa Schreb.) no acúmulo de massa seca de plantas daninhas e no acúmulo de nutrientes (N, P, K e S) nas plantas de cenoura da cultivar ‘Alvorada’. Os experimentos foram instalados nas estações de cultivo 2016/2017 e 2017/2018, em delineamento em blocos ao acaso em esquema fatorial 2 x 5, com 5 repetições. O primeiro fator correspondeu a cobertura do solo (com e sem mulch) e o segundo fator aos períodos de convivência com plantas daninhas (0, 15, 30, 60 e 120 dias após a emergência). A convivência com a comunidade infestante causou redução na absorção dos nutrientes e no acumulo de massa seca das raízes das plantas de cenoura, mais intensamente nos cultivos sem o mulch do que nos cultivos com mulch da palha de aveia preta. O uso do mulch pode reduzir em até 75.6% a massa seca das plantas daninhas durante todo o ciclo da cultura.  Portanto, o uso de mulch de palha de aveia preta reduz a mato interferência e permite maior acúmulo de nutrientes e de biomassa nas raízes das plantas de cenoura da cultivar ‘Alvorada

A utilização eficiente da água e da energia é primordial para uma prática agrícola sustentável. Irrigações deficitárias podem contribuir para economia dos recursos hídricos e energéticos. O objetivo do trabalho foi analisar o efeito da reposição hídrica na eficiência da utilização da água e da energia no cultivo de tomate tipo coquetel. O experimento foi conduzido em casa de vegetação, sendo adotado delineamento casualizado com cinco níveis de reposição hídrica (25, 50, 75, 100 e 125% da evapotranspiração da cultura (ETc)) e seis repetições. Foram avaliados componentes morfológicos (número de cachos, número de abortos, massa fresca da parte aérea, diâmetro do caule e altura), índice SPAD (Soil Plant Analysis Development), demanda hídrica, produtividade, uso de energia e produtividade energética. Os dados foram analisados por análise de variância, comparação de médias, análise de regressão e correlação. O desenvolvimento morfológico e o rendimento produtivo apresentaram elevada correlação com a disponibilidade hídrica. O déficit hídrico afetou o crescimento, desenvolvimento e a produtividade do tomate. A lâmina de 75% da ETc demonstrou melhor eficiência da utilização da água e de energia.

A cultura de cártamo (Carthamus tinctorius L.) apresenta interesse agroeconômico devido a sua ampla aptidão de usos, desde ornamental a extração de óleo, com boa adaptabilidade de cultivo em todo país. Porém, esse cultivo ainda apresenta desafios quanto a qualidade de suas sementes, em virtude da alta susceptibilidade ao ataque de fitogêneos. Assim, o objetivo deste trabalho foi avaliar a qualidade fisiológica e sanitária das sementes de cártamo submetidas a diferentes períodos de armazenamento. O experimento foi conduzido em delineamento inteiramente casualizado, 4x7 (lotes de sementes cultivadas na safra 2017/2018:  semeadas no inverno e na primavera de 2017 e no verão e no outono de 2018, e períodos de armazenamento de sementes: 0; 6; 12; 18; 24; 30 e 36 meses sequenciais contabilizados a partir das datas de colheitas), com quatro repetições. As qualidades foram avaliadas pelos testes de germinação, condutividade elétrica, massa seca e comprimento de plântulas, emergência no campo e sanidade. Observou-se que os diferentes lotes de sementes de cártamo apresentam sensibilidade ao armazenamento prolongado, com redução do potencial fisiológico, especialmente do percentual germinativo e de emergência de plântulas. Além do aumento da incidência dos fitopatógenos nocivos sobre essas sementes. Deste modo, recomenda-se o período de até 12 meses, para obter a conservação das sementes de cártamo.

Published: June 2023

This article analyses the approaches of academics seeking to engage with private, public and community-based stakeholders through transdisciplinary research about pressing sustainability challenges and, in particular, climate change; it outlines aspects of the institutional factors which influence transdisciplinary research. A qualitative approach was employed in conducting 10 semi-structured interviews to analyse the challenges and motivations of academic researchers when working with a range of other stakeholders through transdisciplinary practice. Two key contributions are made through this work. First, this article adds to the existing literature on motivations and challenges for undertaking research with private, public and community stakeholders in a cross-disciplinary manner. Second, the current institutional circumstances influencing such research practices are outlined, alongside potential ways forward. The research presented here has been undertaken in light of the experiences of the two lead co-authors as early career researchers coming from the disciplines of sociology and energy engineering, engaging in transdisciplinary research within a local community context in relation to a regional energy transition project.

Published: June 2023

Detailed student perspectives on their involvement in prison education are limited in published literature, yet such contributions are invaluable to education practitioners wanting to create inclusive learning environments. This article focuses on the student experience of taking part in a science outreach programme teaching science in prison in England, which was designed to build confidence in students who face challenges in accessing education pathways. Here, former students share their experiences of the programme, as well as other education courses in prison, and offer guidance on best practices for those engaging in outreach or research with the prison population. In particular, their reflections highlight that by creating and maintaining an environment that is accessible, inclusive and relatable, students from all backgrounds are able to engage in course content, and overcome hidden barriers to accessing education. Furthermore, based on their lived experience, the students offer practical advice with regard to improving future access to education in prison. The aim of this article is to give a voice to students in prison about their education experience, highlighting which aspects of this outreach programme (and other education courses) were impactful for them.

Published: June 2023

O Brasil possui a região semiárida mais populosa e de maior biodiversidade do mundo (Semiárido Brasileiro - SAB). No entanto, nas últimas décadas, núcleos de desertificação têm surgido, um problema que pode intensificar a partir de mudanças climáticas. O objetivo desse estudo foi elaborar a distribuição espacial das áreas suscetíveis à desertificação climática no SAB, considerando cenários futuros de mudanças do clima. O entendimento dessa dinâmica é algo essencial para a gestão agroambiental do SAB. Foram elaborados índices de aridez e proposição de classes climáticas para condição atual (1970-2000) e cenários futuros (2061-2080) do Painel Intergovernamental sobre Mudanças Climáticas (IPCC), levando em conta cenários do Caminhos Socioeconômicos Compartilhados: otimistas (SSP 126) e pessimistas (SSP 585). Os resultados indicam que até o final do século, o clima no SAB deverá tornar-se significativamente mais seco (Kruskal-Wallis = p-value < 0,05), com intensificação do índice de aridez no SSP 585. Nos cenários, a expansão de áreas mais áridas sobre climas úmidos pode alcançar 56.500 km² (10%) no SSP 126 e 140,400 km² (24%) no SSP 585. Consequentemente, espera-se expansão das áreas com alta (622,400 km² a 706,300 km²) e muito alta (4,400 a 21,700 km²) suscetibilidade à desertificação climática no SAB, respectivamente nos cenários SSPs 126 e 585. Confirmando essas projeções, implicaria em riscos socioeconômicos e ecológicos no SAB.

The Modal Argument and a Rejoinder to Contingent Physicalism
Authors: Moreland James
Published: June 2023

Since the time of Descartes, various versions of a modal argument have been proffered for substance dualism. Until recently, the premise most frequently attacked is one that moves from conceivability to metaphysical possibility. However, more recently, a new criticism has surfaced, viz., an argument from contingent physicalism. The purpose of this article is to show that what I take to be the most sophisticated contingent physicalist criticism fails as a defeater of the modal argument. After stating and clarifying my version of the modal argument, I present arguments from contingent physicalist Trenton Merricks that are intended explicitly to be defeaters of premise (2) of the modal argument. Along the way, I give reasons for thinking that these arguments fail as defeaters of (2) and that Merricks’ contingent physicalism is false.

Authors:   Institute of Management and Territorial Development of the Baltic Federal University named after I. Kant, Kaliningrad, Russia, Pankina Inga
Published: June 2023

The article deals with the problems of preliminary investigation in two forms of inquiry. The author makes a connection with the principles of the criminal process. Competitiveness, inner conviction and the presumption of innocence, from the point of view of the author, are not fully realized in the form of an abbreviated inquiry. It is concluded that the process of proving the guilt of a suspect in an abbreviated inquiry does not meet the legislative structure of the presumption of innocence. The author compares the procedural statuses of "suspected" and "accused" and comes to the conclusion that the realization of the rights of a suspect in any form of inquiry does not correspond to the time and limits of the realization of the rights of the accused during the preliminary investigation.

The article discusses various approaches to the definition of the concept of digital twins in the context of the development of the digital economy, the author's definition of the concept of digital twins is proposed, their essence, content and regulation are established. The direction of the legislative process aimed at the development of digital twins is shown, the problems of legal support of digital twins are analyzed, including in the field of aviation, astronautics, medicine, healthcare and architecture. The study used formal-logical methods, analysis and synthesis, as well as a technical-legal method. Attention is drawn to the need for legal regulation of this activity. It is concluded that a digital twin is a virtual copy of any material (and sometimes nonmaterial) object, process or phenomenon. The main goal of digital twins is the range of tasks to be solved, one of which is optimization. The use of digital twins, like many other information technologies associated with the use of the Internet, is necessarily associated with the risk of violating human and civil rights and their legitimate interests. However, many industries are finding innovative ways to create and use digital twins. It is fixed that the concept of "digital twin" can be considered as a general concept for a digital character and a digital profile. The article also reflects the need to revise approaches to state regulation of relations on the use of digital twins and develop common principles harmonized with other states, for example, such legislative norms that, on the one hand, do not interfere with the development of relevant technologies and services, and, on the other hand, protect human rights and legitimate interests.

Published: June 2023

The features of the legal basis of the activity of administrative commissions of some municipalities of the Chelyabinsk region are investigated. It is revealed that the legislation of the Chelyabinsk region does not establish uniform rules for the creation and regulation of the activities of administrative commissions of municipalities operating in the region. This legal gap leads to different approaches in the adoption of title documents for the formation of administrative commissions in different municipalities. The authors conclude that in the absence of legal regulation at the federal level on the creation of administrative commissions provided for by the Administrative Code of the Russian Federation, it is necessary in the legislation of the subject of the Russian Federation to pay special attention to the adoption of clear rules regarding the regulation of the creation of administrative commissions by municipalities. It is advisable to establish uniform requirements: the adoption of regulations on administrative commissions of municipalities should be the competence of exclusively representative bodies of municipalities, the formation of the composition of administrative commissions should be transferred to the competence of municipal administrations. This will establish a uniform classical division of legislative and executive functions of local self-government bodies of the Chelyabinsk region. It is necessary to formulate specific requirements for persons included in the administrative commissions of municipalities, specifying, among other things, the conditions for prohibiting the inclusion of a person in the commission. The article concludes that it is necessary at the legislative level of the Chelyabinsk region to adopt a Model provision on the administrative commission of the municipality of the Chelyabinsk region in order to unify the organizational and legal work on the creation of such commissions at sites.

Published: June 2023

This research investigated the effect of stress of mid-pregnancy shorn Zandi ewes on the live birth weight and body sizes of twin lambs. A total of 96 Zandi ewes, confirmed pregnant with twins, were randomly allocated on day 80 of pregnancy into 4 groups, each group containing 6 replicates (each replicate containing 4 sheep). The experimental groups included: 1. Control, 2. Crutched, 3. Sham-Shorn, and 4. Shorn. Blood cortisol concentrations of the ewes in the experimental shorn treat-ment group increased significantly compared to control (P<0.05). The average length of pregnancy in the ewes of the shorn treatment group was 2 and 1.5 days longer than the control and Sham-Shorn groups (P<0.05). Lambs born from ewes given the shorn treatment were heavier at birth as compared to the lambs of the other treatments, as well as having longer body lengths, arms, and legs (P<0.05). In general, the results showed that the ewes that were shorn in mid-pregnancy had a higher cortisol con-centration, and it had a significant effect on the birth weight and sizes of the lambs compared to other treatments.

Teaching skills are the foundation of teacher’s ability, and normal students, as the reserve army of future teachers, should train teaching skills consciously in their daily life. As a modern teaching technique widely used in training normal students, micro-teaching is of great significance to explore the cultivation of teaching skills. It should be widely introduced into the training of normal university students. However, there are relatively few researches on teaching skills in micro-teaching of chemistry at present, so we devote to studying the key skills that normal students should master in micro-teaching and the training methods of chemistry teaching skills under micro-teaching environment.This paper will use the practical cases in Chinese middle school chemistry teaching to help normal university students majoring in chemistry to master four key teaching skills: import skills, questioning skills , blackboard writing skills and reinforcement skills, so as to help them achieve the ideal teaching effect.
Taiwan / The Apple of Discord in the Pacific Ocean
Authors: Chytopoulou Eleni
Published: June 2023

Taiwan, officially-self called the Republic of China, is an island state close to China, dominating the straits separating the North from the South China Sea (Taiwan Strait or Formosa[1] Strait). Austronesian aborigines originally inhabited the island. Chinese settled it from the opposite coast, while it was a Dutch and Portuguese colony (1624-1668). The island was recaptured in 1683 by the Chinese and remained in their possession until their defeat by the Chinese -Japanese War in 1895. The island returned to China’s sovereignty after the Second World War ended. Taiwan today is a de facto state that has claimed an autonomous course since 1949, even though until 1971, the United Nations recognized Taiwan as the representative of China. However, the People’s Republic of China has not stopped claiming it has legal sovereignty over Taiwan and the Penghu, Kinmen & Matsu Archipelago, and other smaller islands currently under Taiwan’s sovereignty and are located in the East and South China Seas. Is Taiwan a Chinese island, and should it be incorporated into China under the “One China” principle, or will it survive as an independent state with a different political and social system from the People’s Republic of China? Could U.S. support for the Taiwan regime push tensions with China over the edge?
The Interests of the Gulf Monarchies in the Horn of Africa
Authors: Cherkas Bohdan , Novytska Natalia
Published: June 2023

The aim of this article is to analyze the policy of the Gulf monarchies in the Horn of Africa. Close historical ties between two regions have given rise to deep cooperation between African and Arab states nowadays. Gulf monarchies competed for a long time to deepen their political, economic and security impact in the region.

Strengthening economic ties with the Horn of Africa has helped increase food security in the Persian Gulf. Investments by Arab monarchies in modernizing ports in Sudan, Eritrea, Somalia and Djibouti are helping to improve logistics infrastructure in the Northeast Africa. At the same time, the rapid militarization of the region due to the establishment of a number of Gulf states military bases in the Horn of Africa is increasing the level of conflict-generating in the region. The Red Sea and the Gulf of Aden both have strategic importance for the armed support for the military campaign of the Saudi Arabia and the United Arab Emirates coalition in Yemen. That is why the Horn of Africa has also gained strategic importance due to the conflict in Yemen, and therefore the ambitious Gulf states have become increasingly have become increasingly involved in the regional geopolitics. Saudi Arabia and the UAE, as the main ally of Riyadh in the Persian Gulf, are increasingly seeing the Horn of Africa as their “western flank of security.” They are united by the desire to prevent the growing influence of Turkey, Iran and Qatar in this part of the world.

The competition between Saudi Arabia, UAE, Qatar and Iran helps to attract investments, maintain general stability and improve the security situation in the Horn of Africa. Conflict mediation and asset build-up in the Horn of Africa have enabled Saudi Arabia, the UAE and Qatar to establish political influence in the region. The Gulf states are using their growing economic, security and diplomatic influence in Africa to reduce the influence of competitors and gain international support on the world stage.
Roles of Advisory Councils in Urban Governance
Authors: Pawłowska Agnieszka
Published: June 2023

Urban governance (UG) is a place-based network of cooperation between public and non-public actors where public authorities play a strategic role in deciding on city matters. A number of UG actors include advisory councils (ACs), characterized by a long tradition, universality, stability and objectives related to urban affairs. The article aims to identify AC roles in UG. In addition, the author hypothesizes a correlation between the number of official (statutory) and informal (not legally regulated) roles and differences between ACs in terms of the roles they play. The hypotheses were verified in qualitative research. 57 semi-structured interviews were conducted with members of the youth councils, senior citizen councils, sport councils, and councils for residents with disabilities in 16 Polish cities. The interview transcripts were uploaded to QDA Miner for encoding and analysis. It was found that all ACs, regardless of their official roles, play informal roles, and all these roles are related to UG. There is no correlation between the number of official and informal roles, which would make ACs very similar unless the mandatory character of the roles played by the council for residents with disabilities, which differs this AC from the other. The results of the study lead the author to recommend revisions to AC regulations in order to increase their participation in the UG.

Bu çalışmanın amacı, Türkiye’de 2004 ve 2019 yılları için Hanehalkı Bütçe Anketleri (HBA) kullanılarak, tütün harcamalarına ilişkin bir koşullu talep tahmini gerçekleştirmek ve bu yolla tütün harcamalarının diğer ürün gruplarının (gıda, sağlık, eğitim, giyim, ulaşım, eğlence, alkol, barınma, dayanıklı ürünler) tüketimi üzerinde bir dışlama etkisi yaratıp yaratmadığını üç aşamalı en küçük kareler (3SLS) yöntemi ile incelemektir. Tütün harcamalarının dışlama etkisini anlamak, politika yapıcıların tütün tüketimini azaltmak ve daha verimli ve adil harcama şablonlarını teşvik etmek için etkili stratejiler geliştirebilmesi açısından önem taşımaktadır. Elde edilen bulgular, 2004 yılında tütün harcamalarının yalnızca gıda harcamalarını dışladığına işaret ederken, 2019 yılında tütün harcamalarının gıda, eğlence ve barınma harcamalarını dışladığını ortaya koymaktadır. Ayrıca dışlama etkisinin gelir gruplarına göre farklılaştığı da gözlenmiştir.
Strategic Environmental Corporate Social Responsibility (ECSR) Certification and Endogenous Market Structure
Authors: Sharma Ajay , Rastogi Siddhartha
Published: June 2023

This paper extends the findings of Liu, Wang, and Lee (2015. “Strategic Environmental Corporate Social Responsibility in a Differentiated Duopoly Market.” Economics Letters 129: 108–11), along two dimensions. First, we consider the case of endogenous market structure a la Singh and Vives (1984. “Price and Quantity Competition in a Differentiated Duopoly.” The RAND Journal of Economics: 546–54). Second, we refine the ECSR certification standards in differentiated duopoly with analysis of both uniform and discriminating standards. We find that NGO certifier will set the ECSR standards below the optimal level. We show that given the ECSR certification standards, there is a possibility of both price and quantity contracts choices by the firms in endogenous market structure. Additionally, we highlight the market structures emerging due to uniform and discriminating ECSR standards.

The identification of novel anti-infective agents of synthetic and natural origin represents one of the main aims of contemporary drug discovery. In the current work, four different varieties of Nicotiana tabacum, namely, K399, SPG28, Swat No. 1, and Swat No. 2, were studied to assess the antibacterial and antifungal properties of their extracts. The extracts contain anthraquinones, alkaloids, saponins, terpenoids, tannins, resins, steroids, proteins, and carbohydrates, and the antibacterial and antifungal activities were evaluated toward four bacterial and four fungal strains. N. tabacum K399 showed the highest zone of inhibition against E. coli. Similarly, K399 showed the highest antifungal potential, as the highest zone of inhibition for the set was detected against C. albicans. Then, the underlying molecular mechanism was further investigated, and the extracts were tested for their inhibitory potential against urease, an enzyme which is conserved in bacteria and fungi. Additionally, computational tools were enrolled to assess the role of rutin and chlorogenic acid, which are among the main constituents of N. tabacum leaves, in interacting with urease through molecular docking. Combined together, the computational and experimental results support the antibacterial and antifungal potential of N. tabacum extracts, particularly, that obtained from K399 variety.
Influence of the presence of a nitrided layer on changes in the ultrasonic wave parameters
Authors: Mańczak Ryszard
Published: June 2023

In this work, attempts are made to estimate the relationship between the ultrasonic wave parameters and the presence of the nitrided layer. Special samples were prepared, the surfaces of which were ground and then nitrided. The samples were evaluated by ultrasonic method before and after the nitriding. During the tests, three parameters of the ultrasonic wave were recorded i.e., time of wave propagation, dominant frequency of the spectrum and bandwidth. The measurements were repeated ten times. The obtained results indicate, in particular, a reduction in the wave propagation time in the samples after nitriding compared to the samples without the nitrided layer.
The role of psychiatry in diagnosis and treatment of paediatric chronic fatigue syndrome – a scoping literature review
Authors: Dolp Reinhard , Wardle David PR , Khalid-Khan Sarosh
Published: June 2023

Objectives

Paediatric Chronic Fatigue Syndrome (pCFS) is a common condition that significantly disrupts a healthy psychosocial development. Psychiatric symptoms associated with pCFS are conceptualized as either part of its complex etiology, its consequence, or as a comorbidity. However, patients with this condition are rarely seen by psychiatrists. This scoping review aims to explore the role of psychiatry in the diagnosis and treatment of pCFS.

Content

A scoping review of literature was conducted using MEDLINE, EMBASE, Cochrane and PsycINFO. Databases were searched for articles describing psychiatric involvement in the diagnosis or treatment of children and adolescents (age ≤ 18) with pCFS. A grey literature search was also conducted to identify additional guidelines and national recommendations to identify the role of psychiatry in the diagnosis and treatment of pCFS.

The search provided 436 articles of which 16 met inclusion criteria. Grey literature search identified 12 relevant guidelines. Most studies and guidelines did not include any psychiatric involvement in the care of patients with pCFS. If psychiatry was mentioned, it was used interchangeably with psychological interventions or in the context of treating distinct psychiatric comorbidities and suicidal ideation.

Outlook

The role of psychiatry in diagnosis and treatment of pCFS is poorly defined. Future research is required to understand how psychiatrists can contribute to the care of patients with pCFS.
Emotional community and concerted action: on the emotional mobilization mechanism of disinformation in the Anti-extradition Law amendment movement in Hong Kong
Authors: Tang Jingtai , Chen Qiuyi , Xu Mingliang
Published: June 2023

With the large-scale application of computational propaganda, disinformation campaigns have emerged globally in response to the logic of “post-truth” politics. Organized disinformation campaigns operate frequently on overseas social media platforms, with China often being the target. In order to understand the dissemination mechanisms of such disinformation campaigns, the study found that the dissemination of disinformation became a key strategy for the campaign’s emotional mobilization. The main subjects of disinformation have formed an international communication matrix, creating and spreading all kinds of disinformation on a large scale. The “coalition of protesters” is based on the shared emotional experience evoked by disinformation and characterized by the act of spreading disinformation. Then, the widespread dissemination of the corresponding emotions leads to different perceptions of the “target,” thus prompting protesters to adopt different types of collective action. This mechanism of emotional mobilization shows that facts are “too big to know,” which exacerbates confirmation bias and provides more space for the spread of disinformation. The strong emotions embedded in disinformation contributed to the completion of the protesters’ imagination of community, and emotions became the dominant factor in coalescing the group and providing motivational support for collective action.
An investigation into the effect of cross-ply on energy storage and vibration characteristics of carbon fiber lattice sandwich structure bionic prosthetic foot
Authors: Jiang Meijiao , Zhang Junxia
Published: June 2023

Made a pioneering attempt to use the lattice sandwich structure in prosthetic foot design and pioneered the study for the lay-up design of the prosthetic foot. An innovative carbon fiber bionic prosthetic foot was designed using a sandwich structure. The effect of cross-ply on the prosthetic foot’s energy storage properties and vibration characteristics was investigated using the lattice sandwich structure prosthetic foot. The bionic prosthetic foot’s finite element model was constructed under normal working conditions according to international standards. The results indicate that the storage of strain energy increases with an increase in cross-ply under heel-strict working conditions. Under the toe-off condition, the strain energy distribution increases with the increase in cross-ply. The cross-ply number influences the mode of displacement of the bionic foot. The natural frequencies of the bionic foot increase with the increase in the cross-ply.
I «Giornali» di Giuliano Passaro (1526ca.). Note filologiche e linguistiche
Authors: Schweickard Wolfgang
Published: June 2023

The Giornali of the saddler Giuliano Passaro, completed around 1526, have not yet received the attention they deserve. The chronicle, which describes in the Neapolitan vernacular the historical situation of the Realm of Naples, is of considerable interest both from a historiographical and historical-linguistic point of view. Up to now, the printed edition of 1785 has mainly been used for historiographical and linguistic research. However, it presents considerable differences and errors with respect to the manuscripts. A critical edition therefore remains an urgent need. In the present state of our knowledge, the ms. 13324 of the Biblioteca Nacional de España seems to be the closest version to the lost original.
Das Staduto de laudabilæ bachetæ di Marebe
Authors: Videsott Paul , Videsott Gerda , Tolloi Philipp
Published: June 2023

Romance texts dating from the beginning of the 17th century are relatively rare in South Tyrol, but also in the Ladin valleys of Badia and Gardena, because the administration of these two valleys preferred to use German. The few examples of the use of Romance in the Ladin valleys therefore deserve special attention: on the one hand, because they allow conclusions to be drawn on the degree of multilingualism at the time; on the other hand, because their linguistic form is sometimes characterised by code-mixing, which manifests itself in particular in the fact that the formulaic parts of the texts are generally in (Northern) Italian, while the specifically content-related parts are often interspersed with Ladinisms. Such a text, more precisely the translation of the statutes of the jurisdiction of Enneberg (Marebbe) made in 1614 by the then chancellor Caspar d’Alfarëi from the original version codified in German in 1566, is edited here for the first time and analysed and commented on from a historical and linguistic point of view.
«L’eccezione fa la regola»: ma è proprio vero? A margine di un nuovo libro di Matteo Motolese
Authors: Sgroi Salvatore Claudio
Published: June 2023

The author examines the thesis expressed in the title of the volume by Matteo Motolese «L’eccezione fa la regola». Sette storie di errori che raccontano l’italiano (Milano, Garzanti 2022), and especially the notions of «exception» and «error». In the light of the notion of «error», considered as «a usage condemned, generated by a contrasting rule [R-2]», versus a usage approved and generated by a canonical rule [R-1], the author analyses the examples of errors detected by Motolese in the linguistic history of the 7th–8th centuries (Appendix Probi), of the 13th century (Canzoniere Laurenziano), of 1501 (Petrarca, Le cose volgari), 1603 (Vocabolario della Crusca), 1840 (Alessandro Manzoni, Promessi sposi, ed. Quarantana), 1939 (the linguistic policy of Fascism) and 2022 (grammar/spell checkers).
