Chinese maintenance and shift among Chinese migrant youth in Prato (Italy) and its connectedness with new formations of Chinese identity
Authors: Paciocco Adua Elizabeth 
Published: March 2021

Abstract
In view of theory sustaining that there is a nexus between linguistic repertoire, language and social identity, and that habitual language choice is not haphazard, this study explores the habitual use of Chinese – hence Chinese language maintenance (CHLM) – among multilingual Chinese migrant youth in Prato (Italy) to understand the social meaning embedded in it. The youth are multilingual; they speak Chinese and Italian. They exhibit CHLM with parents, as parents are not competent speakers of Italian. Some of the youth who are speakers of Italian, speak Chinese with peers, hence exhibiting CHLM within their generational cohort; while others do not, hence exhibiting Chinese language shift (CHLS). Oral data in which the youth self-present, report on others with whom they share social space, and talk about CHLM indicate that youth who speak Chinese with peers are not integrated into mainstream society; conversely, youth who are integrated shift to speaking Italian with peers. The analysis evidences that the youth’s integration is influenced by their social identity formation and other variables; such as their migration history, Chinese demographics in Prato and language ideology. Further, this study reveals that the youth are characterised by heterogeneity and that it is hierarchically ordered, heterogeneity and hierarchical ordering being indexed by the youth’s CHLM/CHLS and their alignment/disalignment with others that feature in their social space. This finding evidences that different enactments of Chinese identity are developing among Chinese migrant youth in Prato, thus de-essentialising Chinese identity. This study is wide reaching since it contributes to research on CHLM, the social identity formation of Chinese migrant youth populations, as well as new forms of Chinese identity emerging outside of the PRC. Data was analysed using the talk-in-interaction method of narrative analysis that studies oral narratives in which tellers seek to make sense of their human experience.
Sophisticated humor against COVID-19: the Polish case
Authors: Chłopicki Władysław , Brzozowska Dorota 
Published: March 2021

AbstractThe analysis undertaken in the article focuses on a group of memes selected from the database which drew on culture-specific references. Specifically, they embrace the memories of socialist times and call on references to comic films and easily recognized characters in order to bring out the re-discovered absurdity of the current COVID-19 situation. This material seems ideal to revisit Raskin’s early notion of sophistication, which was broadly argued to derive from intertextuality as well complexity of references that function as sources of humor. In all the examples discussed we can observe the intertextual and metatextual elements, multiple levels and shifts in points of view and attitudes as well as the mutual relations of verbal to visual within the meme cycles. In order to identify specific mechanisms of sophisticated humor, we attempt to identify the visual or verbal triggers of overlap of the two worlds in question, and discuss comic mechanisms of sophistication, including attributions of desire, belief and intention (purpose) to characters or the narrator as commentators on events or situations.
Techno-economic approach towards reactive power planning ensuring system security on energy transmission network
Authors: Karmakar Nihar , Bhattacharyya Biplab 
Published: March 2021

Abstract
This research work proposes a planning strategy pertaining to the techno-economic operation of Indian power systems. The proposed strategy focused on the reactive power (VAr) planning (RPP) subject to the system operating cost minimization ensuring system security. To mitigate the RPP issue, unique meta-heuristic hybridized techniques are adopted to size the optimal parameter settings such as alternator’s reactive power, tap settings of transformers etc. instigated by power flow analysis satisfying all equality and inequality constraints. The controlling variables are optimally determined to solve this non-linear RPP problem. The bottleneck for the installation of static VAr compensators at weak buses is also wiped out by different analytical techniques viz. loss sensitivity, power flow and modal analysis. Two different inter-regional transmission networks prevailing in India are considered to measure the adaptability, efficacy and efficiency of the proposed approach. The results obtained by applying the proposed approach have confirmed that network loss-minimization procedures produce an acceptable solution and reduce the operating cost which is especially important in RPP. The responses of bench mark functions and statistical analysis of the outcomes from both systems allow us to assess the overall efficiency and efficacy of the proposed techno-economic planning approach.

Text-linguistic analysis of performed language: revisiting and re-modeling Koch and Oesterreicher
Authors: Werner Valentin 
Published: March 2021

AbstractThe present contribution starts from the general observations (i) that the study of text varieties has commonly emphasized the mode (speech vs. writing) as an essential variable and (ii) that linguistic analyses increasingly consider performed language (i.e., fictional scripted material as represented in telecinematic language and lyrics, for instance) as an object worth studying in its own right. It is recognized (i) that assessing performed language in terms of the traditional spoken-written dichotomy fails due to a number of inherent properties of relevant text varieties and their circumstances of production and reception, and (ii) that schemes applied within conventional (bottom-up) register perspectives may not be fully adequate for a text-linguistic approach toward performed language either. Koch and Oesterreicher’s communicative model (KOM), which takes account of contextual factors as well as of specific linguistic strategies and establishes a continuum between the language of distance and the language of immediacy, as well as three attempts at modifying KOM are introduced. It is argued that both KOM (as a top-down model) and its modifications have weaknesses when dealing with performed text varieties. An enhanced communicative model, including the dimensions synchronicity and authenticity, is sketched out, which could serve both as a starting point and complement for empirical investigations of textual variation whenever performed language is included.

Abstract
When solving, modeling or reasoning about complex problems, it is usually convenient to use the knowledge of a parallel physical system for representing it. This is the case of lumped-circuit abstraction, which can be used for representing mechanical and acoustic systems, thermal and heat-diffusion problems and in general partial differential equations. Integrated photonic platforms hold the prospective to perform signal processing and analog computing inherently, by mapping into hardware specific operations which relies on the wave-nature of their signals, without trusting on logic gates and digital states like electronics. Here, we argue that in absence of a straightforward parallelism a homomorphism can be induced. We introduce a photonic platform capable of mimicking Kirchhoff’s law in photonics and used as node of a finite difference mesh for solving partial differential equation using monochromatic light in the telecommunication wavelength. Our approach experimentally demonstrates an arbitrary set of boundary conditions, generating a one-shot discrete solution of a Laplace partial differential equation, with an accuracy above 95% with respect to commercial solvers. Our photonic engine can provide a route to achieve chip-scale, fast (10 s of ps), and integrable reprogrammable accelerators for the next generation hybrid high-performance computing.

Summary
A photonic integrated platform which can mimic Kirchhoff’s law in photonics is used for approximately solve partial differential equations noniteratively using light, with high throughput and low-energy levels.
Continuous synthesis of gold nanoparticles in micro- and millifluidic systems
Authors: Huang He , du Toit Hendrik , Panariello Luca , Mazzei Luca , Gavriilidis Asterios 
Published: March 2021

AbstractGold nanomaterials have diverse applications ranging from healthcare and nanomedicine to analytical sciences and catalysis. Microfluidic and millifluidic reactors offer multiple advantages for their synthesis and manufacturing, including controlled or fast mixing, accurate reaction time control and excellent heat transfer. These advantages are demonstrated by reviewing gold nanoparticle synthesis strategies in flow devices. However, there are still challenges to be resolved, such as reactor fouling, particularly if robust manufacturing processes are to be developed to achieve the desired targets in terms of nanoparticle size, size distribution, surface properties, process throughput and robustness. Solutions to these challenges are more effective through a coordinated approach from chemists, engineers and physicists, which has at its core a qualitative and quantitative understanding of the synthesis processes and reactor operation. This is important as nanoparticle synthesis is complex, encompassing multiple phenomena interacting with each other, often taking place at short timescales. The proposed methodology for the development of reactors and processes is generic and contains various interconnected considerations. It aims to be a starting point towards rigorous design procedures for the robust and reproducible continuous flow synthesis of gold nanoparticles.Graphical Abstract:
Preparation of a carrier free 124Sb tracer produced in the Sn (p, n) reaction
Authors: Miyazawa Naoki , Uesugi Masaki , Yokoyama Akihiko 
Published: March 2021

Abstract
A carrier-free 124Sb tracer was prepared for determining radioactive 125Sb in highly contaminated and radioactive soil like one taken near the Fukushima Daiichi Nuclear Power Plant. The excitation function for the 124Sb production was measured and compared to previous works to identify the optimum proton energy for the 124Sn (p, n) reaction by a stack method. The maximum production of 124Sb in the reaction was found at an incident proton beam energy of 8–9 MeV. Except for 124Sb, the reaction produced short-lived by-products and practically no 125Sb. Antimony was isolated from tin matrix by dissolving the irradiated target and extracting to isoamyl acetate. Then the carrier-free 124Sb tracer solution was purified by passing it through an anion exchange resin column. The radioactivity of 124Sb was recovered to more than 50% of the production, and provided successfully as a tracer solution free from tin due to the examined chemical procedure.

Authors: Hajirasouliha Farzaneh , Yang Hua , Wu Qiang , Zabiegaj Dominika 
Published: March 2021

Abstract
Critical micelle concentration (CMC) is one of the important nominal characteristics of the surfactants which can be measured using various methods. In this study, to detect the CMC of two ionic surfactants, cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS), two methods were utilized: (a) optical fiber and (b) drop profile analysis tensiometry (PAT) techniques. The spectrum width center and surface tension of the solutions at different concentrations of the surfactant were measured. The preliminary outcomes showed a compliance between optical fiber method and PAT technique. However, there were differences in the behavior of two surfactants in optical fiber measurement. In this method, when the solid surface of fiber is put in the system, the interactions between surfactant molecules and the fiber surface must be carefully considered.

Published: March 2021

AbstractDental implants have been used as far back as 2000BC, and since then have developed into highly sophisticated solutions for tooth replacement. It is becoming increasingly important for the materials used in dental implants to exhibit and maintain favorable long-term mechanical, biological and more recently, aesthetic properties. This review aims to assess the biomaterials used in modern dental implants, introducing their properties, and concentrating on modifications to improve these biomaterials. Focus is drawn to the prominent biomaterials, titanium (Ti) and zirconia due to their prevalence in implant dentistry. Additionally, novel coatings and materials with potential use as viable improvements or alternatives are reviewed. An effective dental biomaterial should osseointegrate, maintain structural integrity, resist corrosion and infection, and not cause systemic toxicity or cytotoxicity. Current materials such as bioactive glass offer protection against biofilm formation, and when combined with a titanium–zirconium (TiZr) alloy, provide a reliable combination of properties to represent a competitive alternative. Further long-term clinical studies are needed to inform the development of next-generation materials.Significance StatementBiomaterials have become essential for modern implants. A suitable implant biomaterial integrates into the body to perform a key function, whilst minimizing negative immune response. Focusing on dentistry, the use of dental implants for tooth replacement requires a balance between bodily response, mechanical structure and performance, and aesthetics. This mini-review addresses the use of biomaterials in dental implants with significant comparisons drawn between Ti and zirconia. Attention is drawn to optimizing surface modification processes and the additional use of coatings. Alternatives and novel developments are addressed, providing potential implications of combining biomaterials to form novel composites that combine and synergize the benefits of each material.

Published: March 2021

Neste texto em formato de carta, a autora faz uma análise da educação capitalista, enfatizando a mudança na função social da educação massiva ao longo do processo histórico. A autora relaciona as transformações sofridas pela educação formal às mudanças na forma de realização dos direitos sociais e da força de trabalho como mercadoria. A reﬂexão contida na carta, sobre as bases que foram criadas para sujeitar a educação à uma forma específca de controlepor parte de grandes conglomerados empresariais, indaga sobre a necessidade de a educação tornar-se um objeto de crítica da economia política. A partir da teoria marxiana, a autora examina a complexa conjuntura atual e os impactos do crescente conservadorismo, que se materializa no aumento do controle militar, religioso e empresarial da educação formal e não formal, modifcando signifcativamente a estrutura educacional e alterando suas práticas e suas relações. De modo que a intenção da carta é chamar atenção para a subordinação e controle do trabalho educativos aos ditames de conglomeradosempresariais, através do ajuste do serviço estatal à lógica de gestão empresarial.

Published: March 2021

Em resumo, a teoria marxista do conflito sustenta que a inflação tem origem naslutas de classe, mais precisamente, na luta pela distribuição da renda (conflito distributivo).Uma outra abordagem marxista defende que a inflação tem suas raízes noprocesso de acumulação de capital8 e que o “Estado pode incrementar deliberadamentea inflação como meio conveniente de lidar com problemas que ele é incapaz deresolver, ou que não deseja solucionar de maneira mais fundamental”9 . Como formade evitar a queda da taxa de lucro (e uma crise), o Estado adota políticas monetária efiscal expansionistas, que permitem a elevação dos preços pelas empresas e a transferênciado aumento dos custos para os consumidores. O problema é que o Estado não consegue controlar a subida de preços e, em algum momento, a inflação pode disparar,obrigando-no a implementar políticas monetária e fiscal contracionistas, o queresultará na queda do lucro e do investimento e em crise.
Blockchain Use Cases Revisited: Micro-Lending Solutions for Retail Banking and Financial Inclusion
Authors: Hugo Hoffmann Christian 
Published: March 2021

Abstract
While blockchain technology is commonly considered potentially disruptive in various regards, there is a lack of understanding where and how blockchain technology is effectively applicable and where it has remarkable practical effects[1]. Against this background, we present and discuss a case study at length on the impact of this technology in the concrete setting of small short-term loans in retail banking. We propose to banks a robust and scalable blockchain technology with proof of stake and limited energy consumption used to streamline their processes, resulting in lower transaction and administration costs. This is made possible by smart contracts. Thereby, we facilitate small scale lending at high frequencies and short-term duration as well as an easier and more efficient way to connect small borrowers and lenders.
Energy Consumption in China’s Construction Industry: Energy Driving and Driven Abilities from a Regional Perspective
Authors: Gao Jingxin , Chen Yunong , Zhong Xiaoyang , Ma Xianrui 
Published: March 2021

Abstract
The construction industry is one of the largest energy consumers in China. It not only uses energy directly but also consumes a large amount of embodied energy hidden in intermediate goods and services from other industries. This paper utilizes the multi-regional input-output (MRIO) model to measure the embodied energy consumption in China’s construction industry at the province level. To quantify the backward and forward linkages between the construction industry and other industries, the energy-driven and energy-driving abilities of the construction industry are investigated for 30 provinces. The results show that the values of the energy-driven coefficients are significantly larger than the energy-driving coefficients, indicating that the construction industry is highly dependent on products from other industries and other regions, not vice versa. The construction industries in the southwest and northwest regions of China have the highest energy-driven coefficients, showing that the construction industries in west China heavily rely on indirect energy embodied in goods and services. This particularly applies in Guangxi and Hainan provinces, which have the highest energy-driven abilities and the lowest energy-driving abilities. The findings can facilitate the policy-makers to examine the critical energy-saving paths.

Abstract
With the continuous development of economy, the bottleneck problem of environmental resources has become increasingly prominent. Enterprise environmental governance technology innovation incentive has become an important issue for the development of government, society and enterprises. Under the control of enterprise’s expected economic target, this paper discusses the synergistic incentive effect of environmental policy and green finance on enterprise’s environmental governance technology innovation decision by using nonlinear programming model. The results show that when the funds for environmental governance technological innovation are insufficient, there is an optimal decision space to use green financial loans to implement technological innovation and upgrade, and then achieve the expected economic goals; Under a given level of environmental governance technology, environmental policies affect whether enterprises can make decisions on technological innovation and upgrading of environmental governance; Green financial mechanism will not. However, when the enterprise makes the decision of environmental governance technology upgrading, it will affect the enterprise’s decision on green financial loan amount. The results of the study have guiding significance for the formulation of environmental policy and green financial policy, as well as the decision-making of enterprise environmental governance technology innovation and upgrading.
The Theoretical and Experimental Analysis of the Maximal Information Coefficient Approximate Algorithm
Authors: Shao Fubo , Liu Hui 
Published: March 2021

Abstract
In the era of big data, correlation analysis is significant because it can quickly detect the correlation between factors. And then, it has been received much attention. Due to the good properties of generality and equitability of the maximal information coefficient (MIC), MIC is a hotspot in the research of correlation analysis. However, if the original approximate algorithm of MIC is directly applied into mining correlations in big data, the computation time is very long. Then the theoretical time complexity of the original approximate algorithm is analyzed in depth and the time complexity is n
2.4 when parameters are default. And the experiments show that the large number of candidate partitions of random relationships results in long computation time. The analysis is a good preparation for the next step work of designing new fast algorithms.
