IL PAESAGGIO LINGUISTICO NELLE SCUOLE MULTIETNICHE DI MILANO: UNA RICERCA E UN PROGETTO DIDATTICO
Authors: Uberti-Bona Marcella
Published: June 2024

Nei contesti multiculturali e plurilingui il paesaggio linguistico consente di cogliere alcune dinamiche sociali quali i processi di integrazione/rivendicazione delle comunitá migranti e i discorsi e gli atteggiamenti, anche impliciti, espressi dalla società di accoglienza verso le loro lingue e culture. Nelle scuole, la didattica quotidiana riflette questa dialettica nel Paesaggio Linguistico (PL) della scuola stessa, mentre lo studio del PL a scuola può incidere su comportamenti e atteggiamenti relativi alle lingue presenti, legittimandole o valorizzandole. Il presente capitolo intende ripercorrere fasi ed esiti di una ricerca e di un progetto didattico pilota sul PL plurilingue svolto in tre istituti comprensivi milanesi selezionati per l’alto tasso di alunni stranieri. La raccolta fotografica e l’analisi del PL scolastico ha permesso di identificare le pratiche e le ideologie prevalenti rispetto alle numerose lingue parlate dagli alunni stranieri. La realizzazione del progetto pilota ha invece sfruttato lo studio del PL del quartiere intorno alla scuola, ben conosciuto dai bambini, per sviluppare negli alunni una maggiore consapevolezza linguistica e per valorizzare il plurilinguismo che caratterizza la comunità scolastica nel suo insieme.
 The linguistic landscape in Milan’s multi-ethnic schools: a research and teaching project
In multicultural and multilingual contexts, the Linguistic Landscape allows us to grasp certain social dynamics such as the integration/revendication processes of migrant communities and the discourses and attitudes, even implicit, expressed by the host society towards the languages and cultures of these communities. In schools, everyday didactics reflect this dialectic in the Language Landscape (PL) of the school itself, while the study of PL at school can affect behaviours and attitudes related to the languages present, legitimising or valorising them. This chapter intends to retrace the phases and outcomes of a research and a pilot teaching project on multilingual schoolscape carried out in three Milanese comprehensive schools (with children from 3 to 13 years old) selected for their high rate of foreign pupils. The photographic collection and the analysis of the schools’ multilingual PL made it possible to identify the practices and ideologies prevailing with respect to the numerous languages spoken by foreign pupils. The implementation of the pilot project, on the other hand, used the study of the PL of the neighbourhood around the school, which is well known by the children, to develop in the pupils a greater linguistic awareness and to valorise the multilingualism that characterises the school community as a whole.

Questo contributo offre una nuova esplorazione del paesaggio linguistico (PL) milanese, che si propone di approfondire le rilevazioni finora raccolte nel database Paesaggi & Lingua, con un focus sulla lingua araba nella zona circostante via Padova. La creazione di un archivio fotografico e l’analisi qualitativa di alcune unità aggiornate alla situazione post-pandemica consente di individuare i contesti in cui la presenza dell’arabo è particolarmente rilevante, come i servizi al cittadino, le attività commerciali e le comunicazioni informali. Il contributo avanza un’ipotesi sulla flessibilità delle categorie classificatorie del PL, propone una nuova tipologia di frame e discute la molteplicità delle strategie linguistiche e semiotiche usate in questi ambiti e volte a negoziare l’identità nello spazio, aprendo la strada a future prospettive di ricerca.
 
Arabic in the Milanese linguistic landscape: perspectives and contexts
 
This paper offers a new exploration of the linguistic landscape (LL) of Milan, aiming to expand on the materials collected so far in the Paesaggi & Lingua database, by focusing on the Arabic language in the area surrounding via Padova. The creation of a photographic archive and the qualitative analysis of some units as they are found in the post-pandemic period allow to identify the contexts in which the presence of the Arabic language is particularly important, such as services for citizenship, commercial activities, and informal communications. This paper prompts the flexibility of LL classification categories, introduces a new type of frame, and discusses the multiplicity of linguistic and semiotic strategies used in such activities, which are aimed at negotiating identity in space. In this way, this paper aims to pave the way for future research perspectives.

Road Traffic crashes not only claim active lives and inflict injuries but also create an economic burden on society through the loss of productivity of the killed or injured persons. The problem of deaths and injuries as a result of road traffic crashes is now acknowledged to be a global public health problem all over the world, especially in low-and middle-income countries like Bangladesh. However, the state of road traffic crashes in a developing country is much worse compared with that of developed countries. For better planning, improvement, maintenance and operations, the total road systems in Bangladesh are assigned primarily to the Roads and Highways Department (RHD) and the Local Government Engineering Department (LGED) which are called rural roads. However, road traffic safety depends on the reduction of road traffic crashes on RHD road networks and simultaneously LGED road networks. However, the key activities taken by the Government for improving road traffic crashes mainly for the road networks belonging to the RHD leaving a huge volume of rural roads. Moreover, the present recording and reporting systems of road traffic crashes are based on the RHD networks leaving the rural roads. Therefore, the actual state of road traffic safety on rural roads is unknown and the present state of road traffic safety in this country is underreporting. So, it is necessary to identify the effects of rural roads for improving the total traffic safety of the country. Since rural roads have no specific traffic crash data and the volume of rural roads is significantly high, it is impossible to consider all the rural roads to evaluate the state of traffic safety. The research was performed by assessing the traffic safety of randomly selected 8 rural roads from each of the country's divisions representing the country's demographic and topographic characteristics through Road Safety Inspection (RSI). The primary and secondary data for this research were collected by road inspections and from the Accident Research Institute (ARI) of Bangladesh University of Engineering and Technology (BUET), RHD, LGED and different publications.

Changing climatic conditions, especially high temperatures and droughts are one of the major factors hindering sustainable maize production in major maize-growing areas of the world. The current study was designed to determine the association between different morphological, physiological, biochemical, and kernel quality-related traits in maize hybrids under water-deficient conditions. The experiment material was comprised of seven indigenously developed maize hybrids from Maize and Millets Research Institute, Yusafwala-Sahiwal (YH-5482, YH-5427, YH-5404, YH-1899, FH-949, YH-5577, and YH-5395), one maize hybrid developed by local seed company i.e., Kissan Seed Corporation (SB-9663) and two maize hybrids developed by multinational seed companies i.e., Corteva Seeds Pvt Ltd. (P-1543) and Syngenta Seed Pvt Ltd. (NK-8441). The experiment was executed under a randomized complete block design with four replications. The results revealed that highly significant genetic variations were present among maize hybrids for morphological, physiological, biochemical, and kernel quality traits under water-deficient conditions except for ear length for which variations were found to be non-significant. Moreover, correlation coefficient analysis depicts a strong positive correlation of kernel yield with days to 50% silking, days to 50% tasseling, stomatal conductance, transpiration rate, total chlorophyll contents, 1000-kernel weight, ear length, and plant height. However, kernel yield was found to be negatively correlated with hydrogen peroxide, superoxide dismutase, and proline contents. Similarly, path coefficient analysis showed that days to 50% silking had the highest direct positive effect on kernel yield followed by 1000-grain weight, starch contents percentage, and ear height. Therefore, parental material selection must be done using these yield-associated trades under water-deficient conditions.

The Public Health Implications of the Global Financial Crisis
Authors: Wang Ruoxuan
Published: June 2024

The Global Financial Crisis resulted in significant economic problems that subsequently led to a public health crisis worldwide. For example, the unemployed suffered from more severe physical and mental health problems than the employed due to the loss of employer-sponsored health insurances. The crisis further exacerbated racial health inequalities that subsequently worsened maternal and child health outcomes, which negatively affected health status of the future generations. This paper provides a comprehensive discussion of the influence that this crisis has had on physical and mental health, health inequalities, and the intergenerational health impact. To respond to the health implications, the government implemented the Affordable Care Act and the Continuation of Health Coverage (CORBA). In the future, policymakers need to increase social safety net programs, especially government health insurance, for vulnerable populations so that another global financial crisis will likely not have such a negative and profound impact on public health outcomes. The motivation of this paper is to emphasize that higher-quality and more comprehensive unemployment health insurance that covers a broader and more diverse set of populations should become available for the unemployed during economic downturns. This article concludes that policymakers need to design health policies in a way that prevents future financial crises from depriving low-income and unemployed people of their right to health care. Policies must become proactive in advocating for health equity and creating opportunities for people to access medical services in a timelier manner, especially during times of financial downturns.

Authors: Wang Boyou
Published: June 2024

This article mainly studies the physical model design and code simulation of a thulium-doped fiber laser that outputs 1750nm laser. The optical fiber laser has been widely used due to its excellent performance compared with other solid-state laser devices. Among all types of fiber lasers, ytterbium-doped fiber lasers possess the highest output power, whereas they seem to be impractical when an output laser with a longer wavelength is required. However, Thulium-doped lasers have huge room for development to solve the problem, whose unique center wavelength characteristics provide them with huge utilization value. This article shows the electronic transition process a of thulium-doped laser and the power transmission diagram in the fiber. Its rate equation and power equation are also listed below. Through paper retrieval and data extraction, the values of laser parameters can be accurately confirmed, and its power curve can also be obtained through simulation. After analyzing the data obtained from the simulation, the working principle of the fiber laser was intuitively displayed, and the performance of the system was further evaluated. Last but not least, several limitations of this experiment will also be discussed, in order to explore the system more thoroughly.
Training ARMAX model based on the Schur-Cohn algorithm to guarantee stability
Authors: He Siyuan
Published: June 2024

The AutoRegressive Moving Average model with eXogenous inputs (ARMAX) is a well-established linear input-output model formulation for time series analysis. This project implements the Schur-Cohn transform algorithm in C++ to detect and analyze the stability of polynomial coefficients of the AutoRegressive (AR) and Moving Average (MA) components within an ARMAX model. Based on this algorithm, an optimization approach is proposed to improve ARMAX model performance under user-specified parameter constraints. The implementations aim to provide an effective computational framework for investigating ARMAX model stability and enhancing model accuracy in time series forecasting. The efficacy of the proposed methodology is validated empirically through model implementation and forecasting performance evaluation on a designated experimental dataset.

A study on the application of building information modeling technology in geotechnical engineering
Authors: Zheng Yunqi
Published: June 2024

Building information modeling (BIM) technology has brought significant changes to the construction industry, but its application in geotechnical engineering is still in its early stages. Despite challenges, an increasing number of professionals recognize the potential of BIM in geotechnical engineering. This paper studies the application of BIM technology in geotechnical engineering, including an analysis of BIMs characteristics, advantages, and challenges. It can be concluded that while facing complex underground environments, data acquisition difficulties, and compromised model accuracy, the integration of geological and soil data requires tools and standards, and subsurface and surface interactions demand intricate simulations. However, through secondary development, functional optimization, and advancements in exploration techniques, BIM still holds promise in geotechnical engineering. It aids assistant engineers in understanding subterranean environments, refining foundational designs, predicting issues, and facilitating construction management. Despite present hurdles, the application of BIM in geotechnical engineering is anticipated to grow gradually with the progress of technology, bringing forth more advantages and transformation.
An in-depth assessment of the long-term effects of global ocean acidification on marine ecosystems
Authors: Zhang Ruoshi
Published: June 2024

The main goal of this study is to establish the long-term effects that ocean acidification has on the biogeochemical processes that involve carbon, nitrogen, and phosphorus in marine ecosystems. Even though scientists have learned a lot about how ocean acidification affects marine species as evidenced by a wide body of literature on the subject, there are still a lot of areas that require further investigation. For example, there exists a dearth of academic studies on the long-term effects of ocean acidification. More study needs to be done to establish what the long-term and cumulative effects of acidity are, especially in terms of how well different species can adapt. A research design that combines laboratory experiments and field surveys has been identified for this study. In order to gain a comprehensive understanding of how ocean acidification affects marine ecosystems, field surveys will be done at the places chosen for the study. A statistical analysis will be done on the pH readings and carbonate ion concentrations. The goal of this process is to identify patterns and links that may point to probable cause-and-effect links between changes in the chemistry of the ocean and the reported changes in life. The results and discussion intend to give a full analysis and evaluation of how acidification of the world's oceans affects marine ecosystems. This will be done by showing, interpreting, and comparing all the important data and findings. The results of this study are critical for establishing how ocean acidification affects marine ecosystems in the long run.
Equality of different definitions of conformal dimension for quasiself-similar and CLP spaces
Authors: Eriksson-Bique Sylvester
Published: June 2024

We prove that for a quasiself-similar and arcwise connected compact metric space all three known versions of the conformal dimension coincide: the conformal Hausdorff dimension, conformal Assouad dimension and Ahlfors regular conformal dimension. This answers a question posed by Murugan. Quasisimilar spaces include all approximately self-similar spaces. As an example, the standard Sierpiński carpet is quasiself-similar and thus the three notions of conformal dimension coincide for it.
 
We also give the equality of the three dimensions for combinatorially p-Loewner (CLP) spaces. Both proofs involve using a new notion of combinatorial modulus, which lies between two notions of modulus that have appeared in the literature. The first of these is the modulus studied by Pansu and Tyson, which uses a Carathéodory construction. The second is the one used by Keith and Laakso (and later modified and used by Bourdon, Kleiner, Carrasco-Piaggio, Murugan and Shanmugalingam). By combining these approaches, we gain the flexibility of giving upper bounds for the new modulus from the Pansu–Tyson approach, and the ability of getting lower bounds using the Keith–Laakso approach. Additionally the new modulus can be iterated in self-similar spaces, which is a crucial, and novel, step in our argument.

The rational development and utilization of renewable clean energy resources such as hydropower, wind energy, and biomass energy is in line with the trajectory of energy development, and plays a major role in establishing a sustainable energy system and promoting national economic development and environmental protection.The race to net zero will redefine global energy security, with secure, resilient and sustainable clean energy supply chains at the heart of the global energy transition.This paper firstly screens and analyzes the risk factors of clean energy supply chain in the context of China's "dual carbon" goals, and preliminarily constructs a risk assessment index system with reference to the SCOR model.The fuzzy comprehensive evaluation method and entropy value method were used to evaluate the impact of risk factors in China's clean energy supply chain, establish a risk assessment model, and then analyze the risk factors of China's clean energy supply chain.Finally, based on the previous research, some suggestions are put forward for the risk management and optimization of China's energy supply chain.
Performance Landscape: The Relationship between Technology and Society under the Influence of Social Media
Authors: Liu Peitong
Published: June 2024

In the era of big data, the massive public opinion data on social media has challenged the traditional top-down framework analysis methods. In 2022, Fudan University published the core teaching material of network and new media communication, Computational Public Opinion in the Era of Big Data: Theories, Methods and Cases. In addition to analyzing the challenges faced by the traditional framework theory, the authors Zhou Baohua and Liang Hai also introduce how to use network analysis methods to cope with the transformation of social relations increased by technological progress. The data of CNNIC's 52nd report revealed that China has driven the whole people to go online, and social media is an important carrier for empty-nest youth to fight against weak localization. Therefore, how empty-nest youth use social media to become citizens, localization and family has become a landscape worthy of attention. By using the data of "Investigation on the use of social media by empty Nest Youth" from 2021 to 2023, this paper focuses on the degree of weak localization resistance of social networks and finds that the short video content produced is not only determined by technology or social factors, but a new communication scene jointly constructed by technology and society. In view of the "aphasia" characteristic of the vulnerable groups using social media in the previous research on rural communication, this paper puts forward corresponding countermeasures and suggestions from three perspectives: ideological and political education, intergenerational support and digital inclusion.

Will the Low-carbon City Pilot Policy Achieve Regional Emission Reduction?
Authors: Liu Wenrui
Published: June 2024

In order to address climate change and promote green and low-carbon development, the Chinese government has implemented a pilot policy for low-carbon cities since 2010 and has continuously expanded the scope of the pilots. Taking the second batch of low-carbon pilot policies as an example, this paper uses difference in difference method to study the impact of low-carbon pilot policies on reducing urban carbon emission intensity based on the panel data of prefecture level cities from 2006 to 2019. It is found that the construction of low-carbon cities has a positive effect on reducing carbon emissions,and this conclusion is still valid under the robustness test. Based on this conclusion,this paper argues that China should further promote low-carbon pilot policies and actively explore the development model of low-carbon cities, especially to improve the livable and green urban environment.

National 4-H Congress is an example of a programmatic effort designed to help youth develop various life skills. For this study, demographic, event satisfaction, and application of knowledge data were collected from 2,154 past Congress participants. Findings revealed that the majority of participants were satisfied or very satisfied with their Congress experience, and 63% of the respondents had used information gained from the event. Continued efforts to ensure future delegations represent the diversity of 4-H are encouraged, along with continued evaluation of event satisfaction levels and the extent to which life skills are developed and retained.
Impacts of State 4-H Council Service: A Phenomenological Study
Authors: Anderson Bradd L.
Published: June 2024

This qualitative study explored the experience of youth serving on the state 4-H council of Missouri, which provides opportunities to serve as ambassadors of the 4-H organization and influence the experiences of younger members. While many 4-H programs have a statewide youth council, there is little research regarding these groups or the impacts of state 4-H council service. This study employed a hermeneutic phenomenological approach to explore the impacts of State 4-H Council service among alumni, within a framework of positive youth development theory. Council service was found to have provided members experience in working with diverse others, created opportunities to expand relational networks, influenced individual actions, and affected changes in both individuals and their contexts.

Published: June 2024

Learning to set age-appropriate boundaries is an integral element of positive youth development. Both parents and youth need guidance in rule-rsetting and negotiating boundaries. North Dakota State University Extension created Boundaries, a program using parent-youth relationships to teach the importance of setting and following rules or boundaries in various environments. Boundaries was written for 7th- through 12th-grade youth and their parents. This study provides an overview of the program’s objectives and curriculum and shares findings from evaluation efforts conducted with over 60 youth and adults during the program’s pilot phase. In six pilot sessions, respondents completed single-session retrospective questionnaires and answered open-ended questions, which were analyzed using descriptive statistics, paired t-tests, and thematic review. Adults reported higher satisfaction than youth with program content and instruction. Both youth and adults increased their knowledge of program-specific content related to boundaries and relationships. Open-ended responses offered positive feedback and suggestions for program improvement. Results suggested the program was perceived positively and increased youth and adult knowledge of boundary setting and social competence in family life and other settings. Key recommendations include increased rigorous evaluation to measure program impacts and focus on effective implementation strategies for the program.
O COMBATE AO RACISMO NA CORTE INTERAMERICANA: REFLEXOS NO CENÁRIO BRASILEIRO
Authors: Souza Lavínia de Almeida
Published: June 2024

O Brasil é um país racista, contudo, com o “bum” da internet e mídias sociais foi possível conseguir mais visibilidade para esta triste realidade. Episódios como o de George Floyd e a situação ocorrida no jogo entre o PSG X Instabul Basaksehir, e no Brasil, o caso de José Alberto Silveira Freitas, demonstram como ainda é importante debater a temática e entender como o racismo está impregnado na estrutura da sociedade que vivemos. O presente artigo, pretende observar de maneira crítica as decisões na Corte Interamericana a respeito da temática e compreender quais os reflexos gerados no cenário brasileiro como consequência destas. Deste modo, usaremos uma metodologia mista (qualitativa e quantitativa) com caráter documental, a fim de podermos aplicar o critério dedutivo para chegarmos à resposta da hipótese levantada ao decorrer deste trabalho. Foi possível concluir o impacto gerado pela Corte, no cenário brasileiro, na medida que compreendemos a importância que a mesma gerou ao criar a Convenção Interamericana contra o Racismo, a Discriminação Racial e Formas Correlatas de Intolerância, pois o Brasil, a partir disto, resolveu movimentar-se e criar um projeto de decreto legislativo que no momento aguarda a aprovação do Senado.
