A Synergic Integration of AIS Data and SAR Imagery to Monitor Fisheries and Detect Suspicious Activities
Authors: Galdelli Alessandro , Mancini Adriano , Ferrà Carmen , Tassetti Anna Nora
Published: April 2021

Maritime traffic and fishing activities have accelerated considerably over the last decade, with a consequent impact on the environment and marine resources. Meanwhile, a growing number of ship-reporting technologies and remote-sensing systems are generating an overwhelming amount of spatio-temporal and geographically distributed data related to large-scale vessels and their movements. Individual technologies have distinct limitations but, when combined, can provide a better view of what is happening at sea, lead to effectively monitor fishing activities, and help tackle the investigations of suspicious behaviors in close proximity of managed areas. The paper integrates non-cooperative Synthetic Aperture Radar (SAR) Sentinel-1 images and cooperative Automatic Identification System (AIS) data, by proposing two types of associations: (i) point-to-point and (ii) point-to-line. They allow the fusion of ship positions and highlight “suspicious” AIS data gaps in close proximity of managed areas that can be further investigated only once the vessel—and the gear it adopts—is known. This is addressed by a machine-learning approach based on the Fast Fourier Transform that classifies single sea trips. The approach is tested on a case study in the central Adriatic Sea, automatically reporting AIS-SAR associations and seeking ships that are not broadcasting their positions (intentionally or not). Results allow the discrimination of collaborative and non-collaborative ships, playing a key role in detecting potential suspect behaviors especially in close proximity of managed areas.
Horizontal Polarized DC Grounded Omnidirectional Antenna for UAV Ground Control Station

Published: April 2021

A new slot-based antenna design capable of producing horizontal polarization for unmanned aerial vehicle (UAV) ground control station (GCS) applications is outlined in this paper. The proposed antenna consists of oversize coaxial cylinders, slots, and slot-feed assembly. Each of the four vertical slots, arranged periodically around the antenna’s outer cylinder, emits a horizontally polarized broad beam of radiation, in phase, to produce an omnidirectional pattern. The antenna possesses a low-ripple ±0.5 dB in azimuth gain (yaw) due to its symmetric axis shape and an enclosed feed within itself, which does not radiate and interfere with the main azimuth pattern. This is crucial for a UAV GCS to symmetrically extend its coverage range in all directions against yaw planes. Simulation and measurement results reveal that the antenna maintains stable gain in the omnidirectional pattern (+0.5 dB) over the entire operational frequency band (2.55 GHz to 2.80 GHz), where S11 is lower than −10 dB. A further advantage of this configuration is its enhanced polarization purity of −40 dB over the full frequency band. The direct-current (DC) grounding approach used in this antenna is beneficial due to its electrostatic discharge (ESD) and lightning protection. Furthermore, its aerodynamic, self-supporting, and surface-mount structural shape makes this antenna a good and worthy choice for a UAV GCS.

Published: April 2021

As the rapid development of high-end intelligent equipment continues, the design requirements for crack and strain monitoring equipment are increasing daily. In this paper, a decoupled monitoring method for strain and cracks based on a multilayer patch antenna sensor is studied. First, the monitoring principle for strain and crack decoupling is analyzed. Second, the design method for the multilayer patch antenna sensor is studied, and the hierarchical arrangement, patch size, substrate layer thickness, and feeding line structure are designed on the basis of this method. A quarter-wavelength impedance converter is designed to perform impedance matching and optimize the resonant frequency information. The effects of strain and crack propagation on the resonant frequency of the patch antenna are analyzed through simulations, and the decoupled monitoring method for the structural stress state and crack propagation is discussed. Lastly, the feasibility of decoupled monitoring of strain and cracks is verified experimentally. The results of the theoretical analysis, simulations, and experiments show that the proposed patch antenna sensor based on the multilayer structure can realize decoupled monitoring of strain and cracks in the structure, and the sensor has broad application prospects.
Resource Allocation for Downlink Full-Duplex Cooperative NOMA-Based Cellular System with Imperfect SI Cancellation and Underlaying D2D Communications
Authors: Amer Asmaa , Ahmad Abdel-Mehsen , Hoteit Sahar
Published: April 2021

In this paper, the interplay between non-orthogonal multiple access (NOMA), device-to-device (D2D) communication, full-duplex (FD) technology, and cooperation networks is proposed, and a resource allocation problem is investigated. Specifically, a downlink FD cooperative NOMA-based cellular system with underlaying D2D communications is proposed, where, in each NOMA group, the strong user assists the weak user as an FD relay with imperfect self interference (SI) cancellation. In terms of reaping spectral efficiency benefits, the system sum rate is to be maximized by optimizing channel allocation. This optimization is based on quality of service (QoS) constraints of D2D pairs and cellular users (CUs), power budget of base station and strong user (cooperative phase), and successive interference cancellation (SIC) constraints. Since the maximization formulated problem is computationally challenging to be addressed, a two-sided stable many-to-one matching algorithm, based on Pareto improvement, performs sub-channel assignment. Extensive simulations are implemented to demonstrate the system performance indicated by different metrics.

Published: April 2021

The increasing rate of antimicrobial resistance (AMR) in pathogenic bacteria is a global threat to human and veterinary medicine. Beyond antibiotics, antimicrobial peptides (AMPs) might be an alternative to inhibit the growth of bacteria, including AMR pathogens, on different surfaces. Biofilm formation, which starts out as bacterial adhesion, poses additional challenges for antibiotics targeting bacterial cells. The objective of this study was to establish a real-time method for the monitoring of the inhibition of (a) bacterial adhesion to a defined substrate and (b) biofilm formation by AMPs using an innovative thermal sensor. We provide evidence that the thermal sensor enables continuous monitoring of the effect of two potent AMPs, protamine and OH-CATH-30, on surface colonization of bovine mastitis-associated Escherichia (E.) coli and Staphylococcus (S.) aureus. The bacteria were grown under static conditions on the surface of the sensor membrane, on which temperature oscillations generated by a heater structure were detected by an amorphous germanium thermistor. Bacterial adhesion, which was confirmed by white light interferometry, caused a detectable amplitude change and phase shift. To our knowledge, the thermal measurement system has never been used to assess the effect of AMPs on bacterial adhesion in real time before. The system could be used to screen and evaluate bacterial adhesion inhibition of both known and novel AMPs.
A Compact Detection Platform Based on Gradient Guided-Mode Resonance for Colorimetric and Fluorescence Liquid Assay Detection
Authors: Gao Jing-Jhong , Chiu Ching-Wei , Wen Kuo-Hsing , Huang Cheng-Sheng
Published: April 2021

This paper presents a compact spectral detection system for common fluorescent and colorimetric assays. This system includes a gradient grating period guided-mode resonance (GGP-GMR) filter and charge-coupled device. In its current form, the GGP-GMR filter, which has a size of less than 2.5 mm, can achieve a spectral detection range of 500–700 nm. Through the direct measurement of the fluorescence emission, the proposed system was demonstrated to detect both the peak wavelength and its corresponding intensity. One fluorescent assay (albumin) and two colorimetric assays (albumin and creatinine) were performed to demonstrate the practical application of the proposed system for quantifying common liquid assays. The results of our system exhibited suitable agreement with those of a commercial spectrometer in terms of the assay sensitivity and limit of detection (LOD). With the proposed system, the fluorescent albumin, colorimetric albumin, and colorimetric creatinine assays achieved LODs of 40.99 and 398 and 25.49 mg/L, respectively. For a wide selection of biomolecules in point-of-care applications, the spectral detection range achieved by the GGP-GMR filter can be further extended and the simple and compact optical path configuration can be integrated with a lab-on-a-chip system.
Optimism and Social Resilience: Social Isolation, Meaninglessness, Trust, and Empathy in Times of COVID-19
Authors: Franke Volker C. , Elliott Charles N.
Published: April 2021

Using the COVID-19 pandemic as an example of an existential threat, we conducted a nationwide survey in March 2020 asking 445 Americans about their hopes and fears, their opinions about the coronavirus pandemic, and their attitudes for getting through the public health crisis. In the present research, we examine the coronavirus pandemic as a complex problem and explore its effects on respondents’ levels of optimism to resolve the public health crisis. While much existing research examines the influence of risk perception on optimism, we specifically measure how respondents’ levels of empathy and trust affect social resilience and relate to hopes and fears for their personal health and public health in the United States. Specifically, we examine respondents’ levels of trust in government and their neighbors as well as their levels of empathy, alienation, and social isolation. Our research confirmed the importance of empathy to counter the spread of the virus while preventing economic collapse. In addition, we found that relational factors such as alienation and trust affect individuals’ levels of optimism or pessimism for getting through the public health crisis.
A Value-Based Framework Connecting Environmental Citizenship and Change Agents for Sustainability—Implications for Education for Environmental Citizenship
Authors: Sarid Ariel , Goldman Daphne
Published: April 2021

Civic agency is acknowledged as a key driver/catalyst for social transformation toward sustainability. Recent environmental citizenship education (EEC) models advocate a transformative approach for addressing environmental unsustainability (addressing underlying structural causes) and the identification of the development of change agents, as both the means for deep social transformation toward sustainability and the outcome of EEC. Given the paucity of studies looking into the psychological attributes of sustainability change agents, this work aims to deepen the theoretical understanding of the motivations that drive individuals to act as change agents and the type and extent of the change that they aspire to effect, with a view to developing competent environmental citizens. To this end, this conceptual work applies Schwartz’s theory of universal values to construct a three-level framework of environmental citizenship (EC) (individual-level, community-level, and socially-transformative-level). Each level reflects an increasing level of change agency that is driven by distinct motivational values and competences. The framework shares affinities with qualitative change agency typologies in the literature but claims that these different qualitative types reflect expanding ‘levels-of-concern’ and an increasing extent of change, as expressed in the EC framework. The paper then discusses curricular implications for the design of meaningful EEC deriving from the framework: Effective EEC entails developing change agency by adapting learning to the EC-level of the learners and the educational organization. The proposed EC/change agency framework provides a scaffold for such curricular adaptation.

This study compared the yield of tuberculosis (TB) active case finding (ACF) interventions applied under TB REACH funding. Between June 2017 to November 2018, Birat Nepal Medical Trust identified presumptive cases using simple verbal screening from three interventions: door-to-door screening of social contacts of known index cases, TB camps in remote areas, and screening for hospital out-patient department (OPD) attendees. Symptomatic individuals were then tested using smear microscopy or GeneXpert MTB/RIF as first diagnostic test. Yield rates were compared for each intervention and diagnostic method. We evaluated additional cases notified from ACF interventions by comparing case notifications of the intervention and control districts using standard TB REACH methodology. The project identified 1092 TB cases. The highest yield was obtained from OPD screening at hospitals (n = 566/1092; 52%). The proportion of positive tests using GeneXpert (5.5%, n = 859/15,637) was significantly higher than from microscopy testing 2% (n = 120/6309). (OR = 1.4; 95%CI = 1.12–1.72; p = 0.0026). The project achieved 29% additionality in case notifications in the intervention districts demonstrating that GeneXpert achieved substantially higher case-finding yields. Therefore, to increase national case notification for TB, Nepal should integrate OPD screening using GeneXpert testing in every district hospital and scale up of community-based ACF of TB patient contacts nationally.
Pricing Strategy for Residential Water in Drought Years. Application to the City of Tianjin, China
Authors: Yu Bing , Li Yu , Chu Jinggang , Ding Wei , Fu Guangtao , Leng Xiangyang , Yang Tiantian
Published: April 2021

In drought years, most residents fail to improve water use efficiency due to residential water supply normally being prioritized in many regions, which makes other low-priority industrial water users suffer more from water shortage. This paper proposes a Pricing Strategy for Residential Water (PSRW), a water tariff that changes on annual time scale, based on the scarcity value of water resources, aiming to promote residential water conservation and reallocate water resources across the residential and industrial sectors during droughts. An optimization model to maximize the total benefit of residents and industrial sectors is introduced based on marginal benefit and price elasticity. The water shortage of industrial sectors is used to reflect the scarcity of water resources, and the lowest water supply standard for households and the maximum proportion of household water fee expenditure (HWFE) to household disposable income (HDI) are used to ensure the residents’ acceptability to price raising. It shows an “S-type” relationship between the optimal price raising coefficient and industrial water shortage, and two turning points are found in the curve, which are the starting and stopping points of price raising. The appearance of starting point depends on the non-negative net benefit, and the stopping point is affected by the factors that represent the residents’ acceptability to price raising. The application to Tianjin, a city in northern China with the rapid growth of population and economy but scarce water resources, shows PSRW is a potential means to improve water efficiency and optimize water resource allocation in water scarcity situations.
Behavioral Parameters of Planarians (Girardia tigrina) as Fast Screening, Integrative and Cumulative Biomarkers of Environmental Contamination: Preliminary Results
Authors: López Ana , Saraiva Althiéris , Gravato Carlos , Soares Amadeu , Sarmento Renato
Published: April 2021

The present study aims to use behavioral responses of the freshwater planarian Girardia tigrina to assess the impact of anthropogenic activities on the aquatic ecosystem of the watershed Araguaia-Tocantins (Tocantins, Brazil). Behavioral responses are integrative and cumulative tools that reflect changes in energy allocation in organisms. Thus, feeding rate and locomotion velocity (pLMV) were determined to assess the effects induced by the laboratory exposure of adult planarians to water samples collected in the region of Tocantins-Araguaia, identifying the sampling points affected by contaminants. Furthermore, physicochemical and microbiological parameters, as well as the presence of inorganic compounds (dissolved aluminum, total barium, total chloride, dissolved iron, total fluoride, total manganese, nitrates, nitric nitrogen, total sulfate, total zinc) and surfactants, were determined on each specific sampling point. The behavioral biomarkers (feeding rate and pLMV) of the freshwater planarians were significantly decreased when organisms were exposed to water samples from four municipalities (Formoso do Araguaia, Lagoa da Confusão, Gurupi and Porto Nacional), sites of the Tocantins-Araguaia hydrographic region—TAHR. Both behavioral biomarkers decreased up to ~37–39% compared to organisms in ASTM medium only. Our results showed that these behavioral biomarkers can be used for fast screening monitoring of environmental samples of freshwater ecosystems, since a decrease in feeding rate and locomotor activity was observed in sites impacted by anthropogenic activities. However, the absence of effects observed in some sampling points does not represent the absence of contamination, since several other classes of contaminants were not determined. In these negative results, the absence of deleterious effects on behavioral biomarkers might only be indicative that the potential presence of contaminants on such sites does not significantly affect the performance of planarians. This fast screening approach seems to be useful to determine contaminated sites in freshwater ecosystems for biomonitoring purposes. This knowledge will help to develop biomonitoring programs and to decide appropriate sampling sites and analysis.
Tensions and opportunities in social prescribing. Developing a framework to facilitate its implementation and evaluation in primary care: a realist review
Authors: Calderón-Larrañaga Sara , Milner Yasmin , Clinch Megan , Greenhalgh Trisha , Finer Sarah
Published: April 2021

Background

Social prescribing (SP) involves linking patients in primary care with services provided by the voluntary and community sector (VCS). Despite growing interest within NHS primary care, it remains unclear how and under what circumstances SP might contribute to good practice.

Aim

To define ‘good’ practice in SP by identifying context-specific enablers and tensions. To contribute to the development of an evidence-based framework for theorising and evaluating SP within primary care.

Design & setting

Realist review of secondary data from primary care-based SP schemes.

Method

Academic articles and grey literature were searched for qualitative and quantitative evidence following the Realist And Meta-narrative Evidence Syntheses — Evolving Standards (RAMESES). Common SP practices were characterised in three settings (general practice, link workers, and community sector) using archetypes that ranged from best to worst practice.

Results

A total of 140 studies were included for analysis. Resources were identified influencing the type and potential impact of SP practices and four dimensions were outlined in which opportunities for good practice arise: 1) individual characteristics (stakeholder’s buy-in, vocation, and knowledge); 2) interpersonal relations (trustful, bidirectional, informed, supportive, and transparent and convenient interactions within and across sectors); 3) organisational contingencies (the availability of a predisposed practice culture, leadership, training opportunities, supervision, information governance, resource adequacy, accessibility, and continuity of care within organisations); and 4) policy structures (bottom-up and coherent policymaking, stable funding, and suitable monitoring strategies). Findings were synthesised in a multilevel, dynamic, and usable SP framework.

Conclusion

The realist review and resulting framework revealed that SP is not inherently advantageous. Specific individual, interpersonal, organisational, and policy resources are needed to ensure SP best practice in primary care.

Dayak people live on the island of Kalimantan and live in groups such as, Iban, Kayan, Bidayuh, Kanayatn and other groups scattered in small groups and have different characteristics from each other. They live in longhouse (rumah panjang ) the traditional houses that have space for some families to live in. The problem is that many People of Kalimantan do not use rumah panjang  as a place to live, this is due to various factors, such as technological and economic advances that have an impact on changing ways of life. Rumah panjang has traditional values to be preserved as a cultural treasure of Indonesia. If the values of the tradition are extinct along with the loss of (radakng) rumah panjang  in West Kalimantan also lost the wealth of Indonesia. The research was conducted to find out the structure of the division of the room from the rumah panjang (radakng) building. A descriptive approach is used to describe parts of the rumah panjang (radakng). The results of the study are rumah panjang (radakng) consisting of Pante (outer terrace), Sami (porch or inner terrace), Bilik (core room of (radakng) longhouse), Jungkar (kitchen) and Dango (barn), there is also a part of the house that does not blend with the core house and each part of the room has a diverse function and rumah panjang as a place of growth of various cultural heritage such as traditional ceremonies, beliefs, dances, musical instruments and gotong royong (community service).

Published: April 2021

The publicity dominance is the characteristic of memoirs “Force of Circumstance” by Simone de Beauvoir. The idea of S. de Beauvoir influences the genre transformation. The scientific problem is to clarify the specifics of a genre. The aim of the article is to highlight the features of the genres in the novels, diaries, memoirs, interludes, tragedies, comedies as genre memoirs, to understand better the ideas of the writer. The methodology is represented by a biographical method in the study. The most important findings are as follows. The result is to interpret systematic, structured, orderly procedural writing activities. The attention is drawn to the writing process. Writing is a passion, mania, which is causing an addiction. The meaning of creativity is the knowledge of people, culture, history, progress. Genre transformations are the basis for explaining the problem in the work: the artist's activity and her place in the history. The existential fear of death is a central part of literary existentialism. The writer embodied the death fear in her own works.
Ukrainian Intellectual Drama of the 2000s
Authors: Virchenko Tetiana , Kozlov Roman
Published: April 2021

In spite of the presence in contemporary scientific works, the terms ‘intellectual drama’ and ‘intellectual theater’ have blurred boundaries. The aim of the article is to identify productive genres and methods of intellectualization in Ukrainian drama of the 2000s. The category of genre was taken as the basis for material structuring. Genre analysis is combined with a poetics analysis of a literary work and an analysis of theatrical techniques that promote intellectualization. Regardless of the genre determined by a writer for a work, no matter what generation an author identifies himself with, the play-writers are common in the importance of keeping eye on the today’s world. But this does not condition the realism of the content of scripts or when performed on the stage. The study confirms that parable drama, intellectual and philosophical drama, biographical drama, drama of the absurd belong to the actual genres of intellectual drama. The synthesis of styles, arts, and acting provocations is dominated on the Ukrainian stage of the 2000s. Escalation of conflict is emphasized by means of special stage features (a moving platform, specific color or sound, etc.). The conflict of self-identification is among the variety of inner conflicts presented in plays.

Published: April 2021

The article notes that each culture has its own «normative» model of the family, characterized by its defining parameters. These parameters reflect different indicators – descriptors – as attributes that determine the corresponding value and behavior in society. The types of family relationships identified by humanitarian science are revealed. It is proved that in a retrospective of the historical development of mankind, the relationships not only of the family and society, but also of the family and the individual changed, which depended on many factors. The article analyzes the negative trends of marriage and family relations, it is noted that along with the form of actual (civil) marriage, there is a tendency to the appearance of a large number of other forms of marriage unions: guest, concubinate, open marriage, business marriage, fictitious, creative union, polygyny, group marriage, same-sex cohabitation, virtual marriage (web-marriage), etc. This trend leads to a change in the content of the phenomenon of marriage, the adoption of actual marriage as a social norm. It is noted that today the semantic attitudes of a person are deformed and the concepts of the purpose and values of life are distorted, there is a noticeable turn of mass consciousness from the collectivist values of the family to the individual values of the person, which to a certain extent disorganizes both family life and social relations. It is noted that according to the results of the study, the authors of this article developed an educational module "Modern Family" for students of a different professional fields.
The Taxa of the Hyponephele lycaon – H. lupina Species Complex (Lepidoptera, Nymphalidae, Satyrinae): Deep DNA Barcode Divergence despite Morphological Similarity
Authors: Lukhtanov Vladimir A. , Pazhenkova Elena A.
Published: April 2021

The genus Hyponephele includes about 40 species distributed throughout the southern part of the Palaearctic area. Within this genus, the taxa of the H. lycaon – H. lupina species complex are similar with respect to the wing pattern and genitalia structure.
Here we revise this group using analysis of butterfly morphology, DNA barcodes, and study of the type material. We show that, with a few exceptions, the species in this group are allopatric in distribution. Allopatry in combination with phenotypic similarity may be theoretically interpreted
as evidence for the conspecifity of these taxa. Here we falsify this hypothesis by using DNA barcode analysis. We show that the species of this complex are genetically very distant and cannot be combined together as a polytypic species. We also demonstrate that H. lupina consists of
two deeply diverged allopatric clades, H. lupina s. s. and H. mauritanica comb. & stat. nov. The barcode p-distance between these taxa (3.4-4.9%) is significantly higher than the generally accepted 'standard' minimum interspecific divergence (2.0-3.0% ) threshold. These two
clades can also be distinguished by the color of the upperside of the wing in males (brown with conspicuous golden reflection in H. lupina ; dark brown without golden reflection in H. mauritanica) and by details in male genitalia and male androconia structures. Syntypes of Hyponephele
sifanica, H. cheena cheena, H. cheena iskander, and H. cheena kashmirica are studied and figured.

Published: April 2021

It is thought that chronic liver disease affects a person's risk of cardiovascular disease (CVD) development. The aim of this study was to assess the effect of Chronic Hepatitis B (HBV) infection, Chronic Hepatitis C (HCV) infection, and liver damage on cardiovascular risk and selected
vascular parameters contributing to CVD risk. This case-control study included a group of 114 patients composed of 34 patients with HBV, 35 patients with HCV, and 45 patients as the control group. Cardiovascular risk was assessed by analyzing classic risk factors, and the SCORE system. The
following arterial properties were analyzed using applanation tonometry with SphygmoCor Vx technology: central systolic blood pressure (cSBP), central pulse pressure, augmentation pressure, augmentation index, and carotid-femoral pulse wave velocity (PWV). Asymmetric dimethyloarginine (ADMA)
blood levels were analyzed using ELISA as a marker of vascular function. In a univariable analysis we found no significant differences between the hepatitis B, hepatitis C, and control groups in terms of PWV (respectively: median 7.2 [Q25-Q75 6.4-8.5], 7.3 [6.9-8.7], 7.8 [6.5-8.9]), cSBP (115
[109-126], 118 [107-123], 116 [107-129]), ADMA (0.52 [0.47-0.60], 0.53 [0.45-0.62], 0.58 [0.51-0.63]), SCORE (0 [0-1], 0 [0-2], 0 [0-2]). No significant differences in cardiovascular variables were observed between cirrhotic and non-cirrhotic patients. A multivariable analysis confirmed the
above findings. (PWV, p=0 . 29; cSBP, p=0.26; ADMA, p=0.19). We concluded that chronic hepatitis B or C was not independently associated with an adverse cardiovascular risk profile nor with an unfavorable pattern of vascular parameters contributing to CVD risk in our study population, even
in the case of liver cirrhosis. The same was true for blood ADMA levels.

Published: April 2021

As an important way of converting mechanical energy into electric energy, a piezoelectric nanogenerator (PENG) has been widely applied in energy harvesting as well as self-powered sensors in recent years. However, its robustness and durability are still severely challenged by frequent and inevitable mechanical impacts in real application environments. Herein, a fully self-healing PENG (FS-PENG) as a self-powered pressure sensing electronic skin is reported. The self-healing piezoelectric composite and self-healing Ag NW electrode fabricated through mixing piezoelectric PZT particles and conductive Ag NWs into self-healing polydimethylsiloxane (H-PDMS) are assembled into the sandwich structure FS-PENG. The FS-PENG could not only effectively convert external stimulation into electrical signals with a linear response to the pressure but also retain the excellent self-healing and stable sensing property after multiple cycles of cutting and self-healing process. Moreover, a self-healing pressure sensor array composed of 9 FS-PENGs was attached on the back of the human hand to mimic the human skin, and accurate monitoring of the spatial position distribution and magnitude of the pressure was successfully realized.
Clima de aula en secundaria: Un análisis entre las interacciones de estudiantes y docentes
Authors: Villanueva Roxana Karina
Published: April 2021

Esta investigación tuvo como objetivo caracterizar el clima del aula y explorar los aspectos que influyen en este a partir de cuatro casos de estudios, conformados por dos docentes y dos aulas de tercero de secundaria de una institución educativa pública. Para el estudio, se realizaron entrevistas individuales a las docentes, entrevistas grupales a los estudiantes y observaciones de aula. Los resultados muestran que el clima en cada caso fue diferente, dado que en cada aula las distintas características de los estudiantes y las docentes interactuaron de manera diferenciada. En la clase de la docente con estilo tradicional y autoritario, se generó un clima desfavorable para el aprendizaje. En la clase de la docente con características del estilo innovador, cognoscitivo y autoritativo, se generó un clima favorable con los estudiantes de mayor autorregulación y un clima menos favorable con los estudiantes de menor autorregulación. Se concluye que las interacciones que ocurren en el aula con más frecuencia están relacionadas al estilo de enseñanza y a la participación de los estudiantes, al manejo de la disciplina y del comportamiento de los estudiantes, y que estas interacciones generan emociones positivas o negativas que permiten caracterizar el clima de aula. Basándose en ello, es importante considerar el estilo de enseñanza y el estilo de manejo de disciplina en la formación inicial docente. Asimismo, se recomienda abrir espacios para la reflexión y la toma de consciencia de los docentes sobre su propia práctica, así como sobre la influencia de esta en los logros de aprendizaje, desarrollo psicosocial y la satisfacción de sus estudiantes.

Introduction. Well-known the fact that obesity, especially its abdominal (visceral) form, is one of the most important risk factors for hypertension.

The purpose: to determine the level of adiponutrin in patients with hypertension and obesity. Assess how the degree of hypertension and obesity affects the level of adiponutrin in our patients with this comorbid pathology.

Materials and methods. The study included 58 patients with hypertension. Grade 1 was diagnosed in 12 (20.69%), grade 2 - in 16 (27.59%), grade 3 - in 30 (51.72%) examined patients. Of these, 32 women and 26 men aged 32 to 79 years (mean age 57.5 ± 10.11 years). Patients underwent anthropometric measurements, assessed lipid profile and changes in carbohydrate metabolism, adiponutrin levels.

Results. The level of adiponutrin in all groups of hypertensive patients with overweight and obesity was significantly increased compared to the control group, but the degree of hypertension did not affect the level of adiponutrin. However, the concentration of the latter in the serum gradually increases according to the duration of hypertension. In addition, the level of adiponutrin increased depending on the degree of obesity, which, in turn, was confirmed by a reliable direct linear relationship between adiponutrin and body mass index.

Conclusions. Based on the data obtained, adiponutrin can be considered as a marker of metabolic syndrome.

José M. F. Pastor y la planificación argentina a mediados de siglo XX
Authors:   , Goenaga María Victoria
Published: April 2021

La presente investigación doctoral comprueba una problemática desdoblada entre la biografía situada del Arquitecto José M. F. Pastor, Arquitecto y Urbanista egresado en 1944 de la Escuela de Arquitectura de la Facultad de Ciencias Exactas, Físicas y Naturales de la Universidad de Buenos Aires, y el contexto disciplinar del planeamiento en Argentina a mediados de siglo XX. Mediante la sistematización reflexiva de planes y proyectos -que como fuentes primarias inéditas permitieron dar testimonio de un camino innovador desde lo teórico e instrumental- se define un momento en el proceso de construcción de las ideas de planeamiento en la Argentina. Asi mismo, se corrobora a lo largo de la tesis, que Pastor se había vuelto un producto del contexto, como tambien emergente de las inflexiones que subyacían a los debates sobre los que se construía la historia –por demas compleja- de la realidad latinoamericana. A fines de la década de 1930, se consolidaba en la Argentina un movimiento de opinión comprometido con resolver el desequilibrio urbano, producto de la metropolización en contraste con la despoblación y el empobrecimiento del interior del país. Ensayistas, literatos y profesionales del urbanismo caracterizaban un país disociado y promovían un sostenido debate institucional en torno a una serie de ideas encuadradas en la planificación democrática. En este contexto, nos interesó examinar la obra del arquitecto José M. F. Pastor como catalizador de estos debates, editor y difusor de un repertorio disciplinar alternativo, en la traducción de un conjunto de factores locales tensionados por la recepción de teorías externas en torno a la renovación disciplinar del urbanismo. Los criterios humanísticos y ecoéticos que desplegó Pastor, poseen una vigencia particular, ya que son hoy – 60 años despues- parte de las mismas discusiones que problematicas actuales han acelerado exponencialmente sin solución.
Muslim Women Stereotyped
Authors: Hamdan Amani
Published: April 2021

In this paper, I use global education theories and principles to deconstruct common myths regarding Muslim women and the Islamic treatment of women. This paper demonstrates how global education theory and principles can be used to deconstruct and reframe the myths and misconceptions perpetuated on Muslim women. The three major themes explored – female circumcision, polygamy, and subordination – are embedded in a single case and serve as a rich illustration of the usefulness of applying global education principles. They have been developed over the past thirty years to deconstruct and reframe western myths and misconceptions regarding Muslim women.
Islamic Revivalism in the Arab World and Its Dialogue with the West
Authors: Dhaouadi Mahmoud
Published: April 2021

This paper seeks to underline two features of transformation in the Arab world since the late 1960s. First, that region’s religious transformation or ṣaḥwah(awakening) has been a general and overwhelming phenomenon. The pulse of Islam’s global surge can be easily observed at various levels of contemporary Arab countries: the individual and the collective, as well as their political behavior and organization. Second, the great tension between the West and Islam, particularly after 9/11, constituted a sort of change in the relationship between these two parties. I argue that these tensions could be reduced and minimized if the West were to improve its linguistic and cultural ties with Arab societies. The perspective of cultural sociology is very helpful in clarifying how to enhance such a dialogue. I shed light on these two topics through what I call a Homo Culturus perspective.
On the convergence of the barycentric method in solving internal Dirichlet and Neumann problems in $\mathbb{R}^2$ for the Helmholtz equation
Authors: Il'inskii A.S. , Polyanskii I.S. , Stepanov D.E.
Published: April 2021

The application of the barycentric method for the numerical solution of Dirichlet and Neumann problems for the Helmholtz equation in the bounded simply connected domain $\Omega\subset\mathbb{R}^2$ is considered. The main assumption in the solution is to set the $\Omega$ boundary in a piecewise linear representation. A distinctive feature of the barycentric method is the order of formation of a global system of vector basis functions for $\Omega$ via barycentric coordinates. The existence and uniqueness of the solution of Dirichlet and Neumann problems for the Helmholtz equation by the barycentric method are established and the convergence rate estimate is determined. The features of the algorithmic implementation of the method are clarified.
Numerical-analytical method for solving boundary value problem for the generalized moisture transport equation
Authors: Kerefov M.A. , Gekkieva S.Kh.
Published: April 2021

The paper studies qualitatively new equations of moisture transfer, which generalize the Aller and Aller-Lykov equations. The generalization contributes to revealing in the original equations the specific features of the studied massifs, their structure, physical properties, processes occurring in them through the introduction of the notion of the rates of change of the fractal dimension. We have obtained solutions to the constant coefficient difference equations as a system arising when using the method of lines for the equations with a Riemann-Liouville time fractional derivative with boundary conditions of the first kind. A priori estimates are obtained that imply convergence of the obtained solutions to systems of ordinary differential equations with variable fractional coefficients. Numerical tests have been carried out to confirm theoretical results of the study.
Relaxation of the attainability problem for a linear control system of neutral type
Authors: Chentsov A.G. , Sesekin A.N.
Published: April 2021

The problem of control of a linear system of neutral type with impulse constraints is developed. In addition, a given system of intermediate conditions is assumed. A setting is investigated in which a vanishingly small relaxation of the mentioned restrictions is allowed. In this regard, the attainability domain (AD) at a fixed time of the end of the process is replaced by a natural asymptotic analog, the attraction set (AS). To construct the latter, we use the construction of an extension in the class of finitely additive (f.-a.) measures used as generalized controls. It is shown that the AS coincides with the AD of the system in the class of generalized controls – f.-a. measures. The structure of the mentioned AS is investigated.
Essays on the economics of energy and real estate management
Authors:   , Lang Ghislaine

Building energy retrofits are popular targets of public incentive schemes to curb emissions. For an efficient allocation of resources, policy-makers are required to compare benefit estimates of avoided carbon emissions with reliable estimates of each intervention's associated implicit carbon price (i.e., the net social cost of reducing CO$_2$ emissions by one tonne). In this thesis, I use data for a unique portfolio of 548 multi-unit buildings to provide novel evidence on heterogeneous effects of alternative energy efficiency interventions on energy use and the implicit carbon price. My results confirm that frequently subsidized measures such as wall insulation and windows replacement achieve significant energy savings, yet turn out to be a relatively expensive strategy to abate CO$_2$. By contrast, findings for smart thermostats suggest that new technologies can achieve significant savings at a relatively low cost. Despite public incentive schemes and the expected private and pro-social benefits, the level of realized investments remains low, and a burgeoning literature proposes ex-ante information to guide owners' investment decisions. In this context, this thesis also includes a discrete choice experiment on a sample of 511 homeowners to estimate their valuation of alternative replacement heating appliances. Results show that homeowners' willingness to invest in energy efficiency goes beyond financial savings, and that choices are unaffected by ex-ante information on heating costs. By contrast, this thesis also includes a stated choice multiple price list applied to 406 tenants in order to estimate acceptability of rent increases in exchange for improved energy efficiency of the heating system. Findings show that tenants' average willingness to pay for energy efficiency is statistically and economically significant, and can be stimulated further with ex-ante information on heating costs. Information on CO$_2$ tax payments has no incremental effect.
