Social Norms Based Eco-Feedback for Household Water Consumption
Authors: Ramli Ukasha
Published: March 2021

Physical water scarcity is a growing threat to people’s lives around the world. Non-pecuniary interventions that encourage water conservation amongst households are an effective tool to promote sustainable consumption. In a randomised field experiment on 3461 UK households, a social norms based eco-feedback intervention was found to reduce water consumption by around 5.43 L a day or by 1.8% over 29 months. This effect did not persist for the 10 months after the intervention was stopped suggesting a lack of habit formation. Unlike previous studies, households with low consumption at baseline reduced their consumption the most, while high consumers did not. Heterogeneity was also found across quantile treatment effects, where households in the top and bottom quantiles increased their consumption. These results further contribute to the growing evidence on the effectiveness of combining social norms and eco-feedback as an intervention for conservation.

While the need to educate for the formation of environmentally committed citizens is something that has always been recognized, currently however it has become an obligation. The present study analyzes the Doñana, Biodiversity and Culture Program from the perspective of its participants. The program is part of the action being carried out with schools intending to teach environmental citizenry using the context of protected natural spaces, in this specific case, the Doñana National Park. The Park’s managers and public guides were interviewed, and observation records of the process were collected. These were later analyzed by means of a category table elaborated within the project Patrimonial Education for Citizens’ Territorial and Emotional Intelligence, of which this study is a part. The consistency of the informants was verified, as also was the practice observed, showing the importance of the socio-identity framework, of critical thinking, and of socio-affective relationships with the territory.

Authors: Robles Moral Francisco Javier , Fernández Díaz Manuel
Published: March 2021

The digital revolution has transformed the ways of doing, acting, and training in the university field. For this reason, as an objective of this work, social media was used to generate and share knowledge related to sustainability, classification of living beings, and the functioning of the human body. The information was collected through questionnaires, that were completed before and after the intervention program, as well as the work carried out by the students. The participants were 131 students enrolled on the Primary Education degree course of the University of Murcia. The students were well aware of social media, although initially not their educational use. This perception changed when having to make concrete proposals with Instagram and Pinterest, since students valued the wide potential of the use of these networks in teaching. As a result of this intervention, 266 images were generated on Pinterest related to the classification of living beings and 67 about the devices and systems of the human body. Additionally, in terms of the activity on Instagram, 213 publications were created, reaching 1454 followers and 7885 likes. In addition, the participants recognized social media as a source of resources for education, and therefore teachers must explore all the possibilities they offer.
The Constrained Air Transport Energy Paradigm in 2021
Authors: Jiménez-Crisóstomo Abel , Rubio-Andrada Luis , Celemín-Pedroche María Soledad , Escat-Cortés María
Published: March 2021

The increasing relevance of air transport as a contributor to climate change requires the development of emissions reduction technologies in a socio-economic and cultural context, where demand and air traffic have traditionally held sustained growth rates. However, the irruption of COVID-19 in 2020 has had an enormous negative impact on air travel demand and traffic volumes. Coincidentally, during 2020, new technology proposals for emissions reduction based on use of hydrogen and synthetic fuels have emerged from the aviation stake holders. By following a novel approach connecting the analysis of expectations of technology developments and their deployment into the fleet to market constraints, this study discusses how, even considering the new technology proposals and even if the COVID-19 has led to a completely different scenario in tourism and aviation, the air transport energy paradigm will remain unchanged in the upcoming decades as a consequence of market constraints, aircraft complexity, compliance with safety requirements, and extended life cycles. In this frame, aviation needs to keep on pursuing the abatement of its emissions while managing social expectations in a realistic manner and leaning on compensation schemes to achieve emissions contention while new technologies become serviceable in the longer term.
On the Sustainability of Local Cultural Heritage Based on the Landscape Narrative: A Case Study of Historic Site of Qing Yan Yuan, China
Authors: Feng Di , Chiou Shang-chia , Wang Feng
Published: March 2021

As a feature of local cultural heritage, historical garden sites should not only focus on landscape sightseeing, but should also champion the sustainability of cultural heritage and promote the local community’s wellbeing. This article uses the landscape narrative method to explore how the local public, with both professional and non-professional backgrounds, manages the cultural heritage and enhances its sustainability. Qing Yan Yuan is a historical garden site in Huai’an, Jiangsu Province, China, and constitutes the research area of this study. This article firstly conducts in-depth interviews with local residents with non-professional backgrounds; then, it collects relevant information from professionals, such as introductions, comments, news, periodicals, etc.; finally, it adopts the content analysis method to decode, summarize and sort out accordingly. Through the analysis of landscape narrative data, this paper found that three cultural heritage value strategies are used by the public: (1) origin landscape narrative; (2) functional landscape narrative; (3) meaningful landscape narrative. The origin landscape narrative is the expression of a cultural heritage value of “past presentation”; the functional landscape narrative is a cultural heritage value of “place identity”; the meaningful landscape narrative shows a cultural heritage value of “future education”; all these together constitute the local public subjective conception of the sustainability of cultural heritage.

Published: March 2021

Compost is considered a soil-amending product that can be used for soil improvement and to increase the productivity of organic vegetable crops. Composting can be an alternative solution for solid waste management. In this research, the efficacy of various bakery wastes and bulking agents, such as cow dung, to produce compost were studied. The bin composting method was applied in this research. Commercial effective microorganism was used to study its effectiveness in composting bakery waste compared to common ways of composting. Six compost trials were designed by using different ratios of feedstocks such as creamy and non-creamy bakery waste, paper boxes, eggshells, cow dung, dry leaves, and effective microorganism (EM). For the assessment of the maturity, stability, and quality of the compost, various physical and chemical parameters were routinely monitored, including temperature, pH, electrical conductivity (EC), moisture content, water holding capacity (WHC), phytotoxicity and color intensity of water extract, total organic carbon (TOC), total nitrogen (N), phosphorus (P), potassium (K), and C/N ratio. All six compost trials reached the four important phases of temperature, which are the mesophilic phase, thermophilic phase, second mesophilic phase (cooling phase), and maturation phase. The pH, EC, N, P, and K of every compost trial complied with standard compost requirements. Phytotoxicity study proved that all the compost trials were phytotoxic-free when tested with Phaseolus vulgaris (green bean). The water holding capacity of all six trials ranged from 2.18 to 4.30 g water/g dry material. Various compost trials achieved C/N ratios ranging from 12.01 to 14.48, which is considered within the satisfactory limit. The results showed that bakery waste can be turned into compost, with its quality complying with standard requirement.
EPC Labels and Building Features: Spatial Implications over Housing Prices
Authors: Barreca Alice , Fregonara Elena , Rolando Diana
Published: March 2021

The influence of building or dwelling energy performance on the real estate market dynamics and pricing processes is deeply explored, due to the fact that energy efficiency improvement is one of the fundamental reasons for retrofitting the existing housing stock. Nevertheless, the joint effect produced by the building energy performance and the architectural, typological, and physical-technical attributes seems poorly studied. Thus, the aim of this work is to investigate the influence of both energy performance and diverse features on property prices, by performing spatial analyses on a sample of housing properties listed on Turin’s real estate market and on different sub-samples. In particular, Exploratory Spatial Data Analyses (ESDA) statistics, standard hedonic price models (Ordinary Least Squares—OLS) and Spatial Error Models (SEM) are firstly applied on the whole data sample, and then on three different sub-samples: two territorial clusters and a sub-sample representative of the most energy inefficient buildings constructed between 1946 and 1990. Results demonstrate that Energy Performance Certificate (EPC) labels are gaining power in influencing price variations, contrary to the empirical evidence that emerged in some previous studies. Furthermore, the presence of the spatial effects reveals that the impact of energy attributes changes in different sub-markets and thus has to be spatially analysed.

Published: March 2021

The United Nations has adopted 17 sustainable development goals for 2030 with environmental sustainability being one of the main pillars. A key point to address this pillar is the proper management of waste generation. Within the broad spectrum of waste types, food loss and waste is produced worldwide in large quantities. In this framework, the development of composite indexes is recommended to measure the level of compliance of any context with Sustainable Development Goals. This work presents a novel composite index for food loss and waste generation and management systems, the so-called sustainable development goals-food (SDG-Food) index, aiming to determine the level of compliance of any concrete national, regional, or local context regarding five different sustainable development goals with a water-climate-food nexus thinking. The pilot case study of Spain is presented by analyzing the environmental performance between 2015 and 2040 in a context of (i) compliance and (ii) non-compliance with the Paris Agreement targets. Additionally, four different diets are assessed. Results suggested a numerical index score of 13.79, highlighting the categories of eggs, cereals, meat, and vegetables, and the stages of agricultural production and consumption, as the furthers ones for compliance with the five SDG assessed. Moreover, the scenario of compliance with the Paris agreement targets presented better values for all stages, and a vegan diet was highlighted as the one with the best index score.

Authors: Lixăndroiu Radu , Cazan Ana-Maria , Maican Cătălin Ioan
Published: March 2021

The Internet as a shopping and purchasing medium has become an extensively researched topic. Augmented realty, in particular, allows consumers to explore their options and make personalised changes while shopping online. Our study aims to analyse the symmetry between the attitudes towards using the traditional electronic online shopping and the electronic commerce that uses augmented reality. We also investigate the effects of personality traits and the attitudes towards the Internet on the two electronic commerce forms. Our results show that the buying intention in online shopping is significantly higher in the case of augmented reality. Our results also reveal associations between personality traits and online buying behaviours, i.e., neuroticism and the openness to experiences being associated with the willingness to buy online. On the other hand, personality traits are proved to predict buying impulsiveness, the highest weight being represented by low emotional stability and high external locus of control. Further research should also include other dimensions, such as the perceived risks associated with online purchasing, self-efficacy or anxiety towards technology.
Hybrid Model Development for HVAC System in Transportation
Authors: Gálvez Antonio , Seneviratne Dammika , Galar Diego
Published: March 2021

Hybrid models combine physics-based models and data-driven models. This combination is a useful technique to detect fault and predict the current degradation of equipment. This paper proposes a physics-based model, which will be part of a hybrid model, for a heating, ventilation, and air conditioning system installed in the passenger vehicle of a train. The physics-based model is divided into four main parts: heating subsystems, cooling subsystems, ventilation subsystems, and cabin thermal networking subsystems. These subsystems are developed when considering the sensors that are located in the real system, so the model can be linked via the acquired sensor data and virtual sensor data to improve the detectability of failure modes. Thus, the physics-based model can be synchronized with the real system to provide better simulation results. The paper also considers diagnostics and prognostics performance. First, it looks at the current situation of the maintenance strategy for the heating, ventilation, air conditioning system, and the number of failure modes that the maintenance team can detect. Second, it determines the expected improvement using hybrid modelling to maintain the system. This improvement is based on the capabilities of detecting new failure modes. The paper concludes by suggesting the future capabilities of hybrid models.
Numerical Integration of Weight Loss Curves for Kinetic Analysis
Authors: Conesa Juan A.
Published: March 2021

Research abounds in the literature on kinetic analyses using thermogravimetric (TG) runs. Many of these studies use approximations of integral or derivative forms of the kinetic law and all of them use programmed temperatures. In the present work, a numerical integration procedure was discussed and applied to different examples. We focused on materials presenting a single decomposition curve as well as other materials with more complex processes. Different examples were explored, and the methodology was applied to a number of wastes such as coffee husks, polystyrene and polyethylene. In all cases, the actual temperature measured by thermocouples close to the sample is used, and several runs are fitted using the same kinetic parameters, giving robustness to the results.

Dengue has been a perennial public health problem in Medan city, North Sumatera, despite the widespread implementation of dengue control. Understanding the spatial and temporal pattern of dengue is critical for effective implementation of dengue control strategies. This study aimed to characterize the epidemiology and spatio-temporal patterns of dengue in Medan City, Indonesia. Data on dengue incidence were obtained from January 2016 to December 2019. Kulldorff’s space-time scan statistic was used to identify dengue clusters. The Getis-Ord Gi* and Anselin Local Moran’s I statistics were used for further characterisation of dengue hotspots and cold spots. Results: A total of 5556 cases were reported from 151 villages across 21 districts in Medan City. Annual incidence in villages varied from zero to 439.32 per 100,000 inhabitants. According to Kulldorf’s space-time scan statistic, the most likely cluster was located in 27 villages in the south-west of Medan between January 2016 and February 2017, with a relative risk (RR) of 2.47. Getis-Ord Gi* and LISA statistics also identified these villages as hotpot areas. Significant space-time dengue clusters were identified during the study period. These clusters could be prioritized for resource allocation for more efficient prevention and control of dengue.

Published: March 2021

Plasmacytoid variant of urothelial carcinoma is a rare subtype of urothelial carcinoma that has poor prognosis. We describe two cases of patients with the plasmacytoid variant of urothelial carcinoma (PVUC) who had initial response to neoadjuvant chemotherapy followed by radical cystoprostatectomy and lymph node dissection but presented with early relapse and disease progression manifesting with intestinal obstruction and peritoneal carcinomatosis. Tumor genomic sequencing revealed mutations and alterations in ARID1A, CDH1, PIK3CA, RB1 loss, and TERT promoter, as well as tumor mutational burden of 10 Muts/Mb treated with pembrolizumab with a minimal response. A further review of the literature regarding this rare variant is discussed here.

Published: March 2021

Glycan–protein interactions are highly specific yet transient, rendering glycans ideal recognition signals in a variety of biological processes. In human norovirus (HuNoV) infection, histo-blood group antigens (HBGAs) play an essential but poorly understood role. For murine norovirus infection (MNV), sialylated glycolipids or glycoproteins appear to be important. It has also been suggested that HuNoV capsid proteins bind to sialylated ganglioside head groups. Here, we study the binding of HBGAs and sialoglycans to HuNoV and MNV capsid proteins using NMR experiments. Surprisingly, the experiments show that none of the norovirus P-domains bind to sialoglycans. Notably, MNV P-domains do not bind to any of the glycans studied, and MNV-1 infection of cells deficient in surface sialoglycans shows no significant difference compared to cells expressing respective glycans. These findings redefine glycan recognition by noroviruses, challenging present models of infection.

Published: March 2021

There is mounting evidence that the microbiome plays a critical role in training and maturation of the host immune system. Pre-clinical and clinical studies have shown that microbiome perturbation is correlated with sub-optimal host responses to vaccines and cancer immunotherapy. As such, identifying species of commensal bacteria capable of modulating immunological outcomes is of considerable interest. Currently, the lack of reliable primary immune cell-based assays capable of differentiating immuno-modulatory properties of various commensal bacteria is a major limitation. Here, we demonstrate that primary human monocyte-derived dendritic cells (MoDC) are capable of stratifying different strains of live and heat-killed commensal bacteria in an in vitro culture system. Specifically, heat-killed bacterial strains were able to differentially modulate co-stimulation/maturation markers CD80, CD83, and HLA-DR, as well as cytokine/chemokine signatures, such as IL-1b, MIP-1a, and TNFa in primary human MoDC. We further validated our observations using the TruCulture® (Myriad RBM, Inc., Austin, TX, USA) whole-blood ex vivo culture system. Using this ex vivo system allowed us to measure immune-altering effects of commensal bacteria in primary human whole-blood. As such, we report that both these primary in vitro and ex vivo systems are robust and enable identification, stratification, and differentiation of various commensal bacteria as potential modulators of host immunity.

Published: March 2021

An induction motor is a key device for an industrial machine. The installation misalignment of the motor will result in derating problems and energy consumption that is generally used to analyze signal faults using the fast Fourier transform (FFT) method. Problems with the rotor affect the non-stationary signal and FFT can be utilized to analyze this problem inefficiently. This paper proposed the testing and analysis of faults in an eccentric rotor at different levels using the stator current detection technique and the calculation of the energy signal coefficient via the wavelet decomposition (WD) method. The experimental results showed that an increase in eccentricity had a linear relation with the energy signal, where R2 was 80.81%. Moreover, the test results illustrated that the proposed method was more efficient than FFT and applicable to motor fault analysis and application in the industrial.

Authors: Ito Hirokazu , Shimizu Takahisa , Wada Yoshimasa , Kaji Hironori , Fukagawa Hirohiko
Published: March 2021

Organic light-emitting diodes (OLEDs) have been studied as a key technology for next-generation displays. Although OLEDs with internal quantum efficiencies of approximately 100% have been achieved using phosphorescent or thermally activated delayed fluorescent (TADF) emitters, little is known about the correlation between the molecular structure of emitters and the lifetime of OLEDs. Here we observed the effect of the molecular structure on the lifetime of OLEDs by utilizing the efficient energy transfer from TADF materials to phosphorescent emitters. We found that specific molecular structures are effective in extending the stability of TADF materials and the OLEDs fabricated using these materials.

Published: March 2021

Energy conversion which takes place in a stack wetted with water is investigated. To clarify the discussion, two cases for working fluid of only air and air containing water vapor are compared. As a result, three conclusions are obtained: 1. In the case of air only, energy generation depends on temperature gradient; 2. In the case of a mixture of water vapor and air, the energy generation depends on the number-density ratio; 3. The energy generation due to water vapor is around 15 times that due to air. These conclusions are thought to be useful for designing a thermoacoustic system capable of low-temperature driving which uses the stack wetted with water.
Quantitative evaluation of ultrasonic cleaning ability using acoustic cavitation signal
Authors: Uchida Takeyoshi
Published: March 2021

The purpose of this study was to establish a new quantitative evaluation index for ultrasonic cleaning ability. We described the relationship between the acoustic cavitation signal generated by acoustic cavitation bubbles and the cleaning ability of an ultrasonic cleaning device. The measured acoustic cavitation signal was broadband noise. Ultrasonic cleaning ability was independently determined as the removal rate of material coatings on a metal surface, as an analog for medical apparatus cleaning. There was a positive correlation between broadband noise and the material removal rate. The results showed that an acoustic cavitation signal has the potential to be used as an evaluation index for measuring the effectiveness of ultrasonic cleaning.
Initial electrical properties of tantalum oxide resistive memories influenced by oxygen defect concentrations
Authors: Li Yuanlin , Tsurumaki-Fukuchi Atsushi , Arita Masashi , Takahashi Yasuo
Published: March 2021

The initial electrical properties of tantalum oxide resistive memory were investigated using four metal electrodes (TiN, Ti, Ta, and Al) and two kinds of tantalum oxide with different amounts of intrinsic oxygen vacancies. The initial resistance depended on the electrode material. This indicated that oxygen scavenging by the electrodes contributed to a reduction in the resistance. However, the resistance change depended on the intrinsic oxygen vacancy concentration introduced during the tantalum oxide deposition. The forming voltage also depended on the electrode metal. For the device with an Al electrode, a clear aluminum oxide layer was identified at the electrode–insulator interface, which was hypothesized to be the origin of the high forming voltage. All factors concerning the oxygen vacancies, i.e. intrinsic vacancies introduced via film deposition and extrinsic vacancies caused by the electrode scavenging effect, influenced the initial state of tantalum oxide, and thus, its switching performance as a resistive memory.

Published: March 2021

We developed high capacitance density and highly reliable Si deep trench capacitors with textured surface and SiN dielectric film. The developed capacitor consists of parallel unit cells with 14.3 μm depth textured surface trench capacitors, using Si wafer process compatible to 3D integration, realizing high scalability and versatility. Various fabrication conditions were experimented with to optimize the electrical characteristics. As a result, over 230 fF μm−2 capacitance density and 9.0 V breakdown voltage were achieved. Regarding reliability, it has been confirmed that SiN dielectric film leads to below 10−9 A cm−2 leakage current density at 1 V and the predicted lifetime of over 50 years at 3.3 V. For low voltage applications, higher capacitance density is available by using thinner SiN dielectric films.

System patroli security akan dioperasikan oleh dua pengguna yaitu petugas security yang akan menginputkan data-data yang wajib diisikan pada saat melakukan kegiatan patroli. Untuk pengguna kedua merupakan admin atau dalam perusahaan disebut koordinator lapangan. Sistem patroli ini dilakukan oleh security secara bergantian sesua dengan shift (jam kerja) masing-masing ,dan petugas security juga memiliki username dan password masing-masing untuk dapat mengakses aplikasi atau system ini. Pada system ini petugas security akan melakukan pelaporan dan akan di validasi oleh admin pengelola.  

Oleh karena itu aplikasi yang berbasis website untuk mengoptimalkan kinerja petugas security yang mengkonversikan sistem patroli yang masih manual menjadi digital. Aplikasi ini juga membantu pengawasan

CCTV disetiap area patroli karna dengan luas area yang dimiliki tidak memungkin untuk perusahaan memasang CCTV pada setiap titik patroli dan tentunya lebih meminimalisir pengeluran yang dikeluarkan oleh perusahaan. Dalam pengawasan ini sistem akan bekerja secara online sehingga dalam semua area patroli security akan mengambil data waktu dan tempat dimana petugas security tersebut melakukan patroli menggunakan waktu server sehingga seakan memaksa petugas security untuk patroli dan melakukan tanggung jawabnya

This study focused on organisational silence and performance of selected small and medium enterprises (SMEs) in Lagos State. The objective of this study is to empirically examined the concept of organisation silence and its outcomes on SMEs operating in Lagos State. Survey research design was employed in this study. Primary and secondary data were used in this study. The target population covers SMEs registered with Nigerian Association of Small & Medium Enterprises (NASME). 100 copies of questionnaire were administered to members of NASME (Lagos State Chapter) as a sample size. 71 copies were duly filled, returned and valid for this study. Descriptive and inferential statistics were used to analyze data collected. Spearman rank correlation was used to test the hypothesis of this study. r =0.70, which 70% level of relationships. The result of the analysis revealed that organisational silence has effect on performance of SMEs in Lagos State. The study recommended that employees should be allowed to participate in decision making that will affect them should be recognized in such a way that will motivates them to break their silence for effective communication.
COLLABORATIVE NEGOTIATION STRATEGY: A PANACEA FOR SUSTAINABLE INDUSTRIAL PEACE IN THE EDUCATIONAL SECTOR OF NIGERIA
Authors: Bankole Akanji Rafiu , Oderinde Michael Adekunle
Published: March 2021

The persistent occurrence of industrial conflict in Nigeria educational sector particularly at tertiary level has apparently impacted negatively on the standard of education in the country. Past studies had traced the frequency of industrial actions in tertiary institutions to the type of negotiation strategy often employed by both labour leaders and management representatives. This study therefore examined the available negotiation strategies with a view to identifying the appropriate one and subsequently suggests what could be done for the two parties to voluntarily embrace the negotiation strategy considered appropriate and effective to achieve sustainable industrial peace. Using the archival method, the study observed that competing negotiation strategy was predominantly used in the tertiary institutions in Nigeria. And due to the confrontational and judgemental nature of the strategy, it could not stem the tide of incessant incidences of industrial action. Also, the study observed that the choice of competing negotiation strategy by both parties was probably due to their negative perception about each other and their behavioural orientation that is grossly defective. Based on the observation and the theoretical framework, it was suggested that training programme on some identified Behaviour Modification Skills (BMS) be organized for both parties. It is anticipated that by acquiring the skills, both parties would consciously change their negative perception to positive and their behavioural orientation would equally be enhanced. Thus, both parties would be willing to apply voluntarily the collaborative negotiation strategy considered appropriate and effective to attain sustainable industrial peace in our tertiary institutions.
AI Ethics in the Public, Private, and NGO Sectors: A Review of a Global Document Collection
Authors: Schiff Daniel , Borenstein Jason , Biddle Justin , Laas Kelly
Published: March 2021

In recent years, numerous public, private, and
non-governmental organizations (NGOs) have produced documents addressing the
ethical implications of artificial intelligence (AI). These normative documents
include principles, frameworks, and policy strategies that articulate the
ethical concerns, priorities, and associated strategies of leading
organizations and governments around the world. We examined 112 such documents
from 25 countries that were produced between 2016 and the middle of 2019. While
other studies identified some degree of consensus in such documents, our work
highlights meaningful differences across public, private, and non-governmental
organizations. We analyzed each document in terms of how many of 25 ethical
topics were covered and the depth of discussion for those topics. As compared
to documents from private entities, NGO and public sector documents reflect
more ethical breadth in the number of topics covered, are more engaged with law
and regulation, and are generated through processes that are more
participatory. These findings may reveal differences in underlying beliefs
about an organization’s responsibilities, the relative importance of relying on
experts versus including representatives from the public, and the tension
between prosocial and economic goals.

Element Edge Based Discretization for TCAD Device Simulation
Authors: Sanchez Juan , Chen Qiusong
Published: March 2021

Technology computer-aided design (TCAD) semiconductor device simulators solve partial differential equations (PDE) using the finite volume method (FVM), or related methods. While this approach has been in use over several decades, its methods continue to be extended, and are still applicable for investigating novel devices. In this paper, we present an element edge based (EEB) FVM discretization approach suitable for capturing vector-field effects. Drawing from a 2D approach in the literature, we have extended this method to 3D. We implemented this method in a TCAD semiconductor device simulator, which uses a generalized PDE (GPDE) approach to simulate devices with the FVM. We describe how our EEB method is compatible with the GPDE approach, allowing the modeling of vector effects using scripting. As an example, this method is applied to solve polarization effects in ferroelectric materials, with examples of a 3D ferro capacitor and a 2D ferroelectric field-effect transistor.

Os direitos humanos fundamentais são garantidos por lei para os homens e mulheres da sociedade contemporânea democrática. Dentre os direitos humanos fundamentais, nos detemos no direito à educação e, consequentemente, as suas contribuições à humanização dos sujeitos, por meio do desenvolvimento de capacidades superiores, dentre elas destacamos a capacidade de ler textos literários e discutimos fundamentado pela teoria histórico-cultural e autores da literatura. Neste contexto, apresentamos o poeta contemporâneo brasileiro Thiago de Mello e suas obras com destaque para “Os Estatutos do Homem”. O critério de escolha advém da própria notoriedade estético-literário da peça que se materializa em um texto de originalidade no grande tema presente em seu enredo, garantindo qualidade literária à escolha. Após reflexões sobre os enunciados de Thiago de Mello apoiado em conceitos bakhtinianos, sugerimos uma proposta prática de leitura com crianças dos anos finais do Ensino Fundamental. Trata-se de atividades com as estratégias de leitura (Souza e Girotto, 2011) a partir do poema sobre direitos humanos, “Os Estatutos do homem”, escrito pelo poeta contemporâneo amazonense.
