Published: February 2023

Previous work assessed the efficiency of temporal integration by human observers for detection of static signals embedded in spatiotemporal (dynamic) noise. In a new paradigm, the signal is spatially displaced form frame to frame. For an ideal observer that integrates the responses of matched filters at different signal locations through time, the performance (d’) remains the same as if the signal were static, improving as the square root of the number of frames in the sequence. We evaluated motion compensated integration by human observers using a 4 AFC detection of a moving (.37 c/frame) Gabor patch (5.5 c/degree) embedded in spatiotemporal Gaussian noise. Observers fixated during the experiment. Performance was measured for increasing number of frames in the sequence (1 to 40). The sequences were displayed at 20 frames/sec; however, each sequence was repeatedly displayed for a total display time of 4 sec. For comparison the experiment was repeated with a non-moving signal embedded in dynamic noise and a signal embedded in static/spatial noise (single frame). Results: For equivalent signal to noise ratios for the ideal observer, the corresponding statistical efficiencies (d’2human/d’2ideal) for human observers were approximately 30% for the static noise, 10% for the non-moving signal in dynamic noise and 7% for the moving signal in dynamic noise. The critical time for the motion compensated integration is in the same range as the spatially local temporal integration; 700-1000 msec.
Fully parallel analog optical calculation of multiple outer products
Authors: Raj K. , Athale R. A. , Savkar V. A.
Published: February 2023

An analog optical processor for evaluating weighted sums of outer products in parallel is described. It uses a linear array of light sources oriented along the diagonal, 2-D spatial light modulators to encode input vectors, a 2-D detector array to generate the output and conventional spherical and cylindrical lenses. This system can be used to multiply two matrices as well as to evaluate a weighted rank-1 synthesis of images in a single clock cycle of the processor. Factors limiting the performance are described. These can be overcome using a linear array of sources and grating array deflectors. Experimental results using eight outer product terms are presented and the implication of this architecture to optical signal and image processing systems are discussed.

Fiber-optic technology for IBM Enterprise systems
Authors: DeCusatis Casimer
Published: February 2023

The IBM System/390 :sup.*:esup. family of mainframe computers is among the first in the computer industry to use fiber optic I/ O channels for high speed data transfer. Known as ESCON (Enterprise Systems Connection) :sup.*:esup channels, these optical links provide significantly higher bandwidth, data rates, and distance than the parallel electrical cables which they replace. The ESCON :sup.*:esup. channels consist of 200 Megabit/s duplex fiber optic links (17 Megabytes/s). Multimode links using 1300 nm LED transmitters and PIN photodiode receivers allow a maximum unrepeated distance of 3 km using 62.5 micron core fiber and 2 km using 50 micron core fiber with a minimum modal bandtvidth of 800 Mhz-km. A single-mode version using InGaAsP laser diodes increases the unrepeated distance to 20 km while maintaining international class 1 laser safety. This paper describes the optical, electrical, and mechanical design innovations of the ESCON :sup.*:esup. channels. Optical link budget modeling will be discussed, as well as design of a duplex optical connector and cable strain relief system. Experimental data will be presented on link performance in harsh environments such as elevated levels of ionizing (gamma) radiation, or customized link designs which can extend the maximum unrepeated distance.
Quantum correlation of polarization of two-photon entangled state in type-II spontaneous parametric downconversion
Authors: Sergienko A. V. , Kiess T. E. , Shih Y. H. , Rubin M. H. , Alley C. O.
Published: February 2023

Polarization correlation measurement of two-photon state generated in type-II spontaneous parametric downconversion (SPDC) has been performed in a single input port beam splitter configuration. Two orthogonally polarized entangled photons with degenerate k vectors were directed to the single input port 50%-50% beam splitter. Polarization were measured with linear and circular polarization entangled state by the use of two polarization analyzers followed by two photon counting detectors. A strong correlation of polarization has been observed. The type of two-photon state generated in Type-II SPDC was tested. A strong dependence of the polarization correlation upon the spectral bandwidth of the detector spectral filter was found and a different correlation between linear and circular polarization entangled state were observed. It seems that the standard theoretical models for SPDC need to be improved in order to provide a comprehensive treatment for the result of the experiment.
Quantum noise in the classical limit
Authors: Franson J. D.
Published: February 2023

Spontaneous emission noise can be thought of as being due to vacuum fluctuations and may appear to be inherently quantum-mechanical in nature. The same can be said of the loss of coherence in which-path experiments, which is due to the entanglement of a photon with some other system in one path through an interferometer. Both of these processes have been considered in the limit of high field intensities in order to determine whether or not they have a classical analogy. It was found that the same phenomena occur classically as well due to chaos. The extent to which these phenomena can or cannot be considered to be inherently quantum-mechanical will be discussed.
Analysis and synthesis of nonuniform grating structures
Authors: Poladian Leon , Sipe John E. , de Sterke C. Martijn
Published: February 2023

Nonuniform Bragg gratings, having periods or modulation depths which vary slowly over the length of the grating, have interesting properties and provide extra degrees of freedom in the design of structures which exploit their reflectance characteristics. Physical insight into the relationship between the slowly varying grating structure and its reflectance spectrum is obtained by displaying the variations in the position and extent of the local photonic bandgap as a function of distance along the grating. This diagrammatic technique provides qualitative information on reflectance strengths and the locations of transmission resonances in the spectrum. This qualitative approach is supplemented by semi-analytical results based on the WKB method.
Field-correction method for scalar waveguide-mode calculations
Authors: Gonthier François , Lacroix Suzanne , Bures Jacques
Published: February 2023

The field correction method is a numerical method for calculation of scalar modes of waveguides with arbitrary index profiles, that can be adequately represented by a two-dimensional array. The method is based on the local minimization of a finite difference approximation of the scalar wave equation by locally modifying the field. The field, also stored in a two-dimensional array, is modified iteratively, point by point, until the effective index of the mode, calculated by integration over the total field, converges to the desired precision. The method thus generates the field and propagation constant of the mode. The boundary conditions determine which low order mode is calculated. Higher order modes are calculated by modifying a field which is orthogonal to that of the lower order modes. The accuracy of the method is limited by the spacing of the grid points which describes the index profile and the field. The method is reasonably fast, though the calculation time depends on the precision required and the index steps, and can easily be implemented on a personal computer. Examples of mode calculations for fused couplers and rib waveguides are presented and component design is discussed.

Authors: Höher Jürgen , Lischke Betty , Petersen Wolf , Mengis Natalie , Niederer Daniel , Stein Thomas , Stoffels Thomas , Prill Robert , Schmidt-Lucke Caroline
Published: February 2023

Objectives

Implementing evidence-based recommendations with the option of patient-individualised and situation-specific adaptations in telerehabilitation may increase adherence with improved clinical outcome.

Methods

As part of a registry-embedded hybrid design (part 1), digital medical device (DMD)-usage in a home-based setting was analysed in a multinational registry. The DMD combines an inertial motion-sensor system with instructions for exercises and functional tests on smartphones. A prospective, single-blinded, patient-controlled, multicentre intervention study (DRKS00023857) compared implementation capacity of the DMD to standard physiotherapy (part 2). Usage patterns by health care providers (HCP) were assessed (part 3).

Results and conclusion

Registry raw data (10,311 measurements) were analysed from 604 DMD-users, demonstrating clinically expected rehabilitation progression post knee injuries. DMD-users performed tests for range-of-motion, coordination and strength/speed enabling insight to stage-specific rehabilitation (χ2= 44.9, p<0.001). Intention-to-treat-analysis (part 2) revealed DMD-users to have significantly higher adherence to the rehabilitation intervention compared to the matched patient-control-group (86% [77–91] vs. 74% [68–82], p<0.05). DMD-users performed recommended exercises at home with higher intensity (p<0.05). HCP used DMD for clinical decision making. No adverse events related to the DMD were reported. Adherence to standard therapy recommendations can be increased using novel high quality DMD with high potential to improve clinical rehabilitation outcome, enabling evidence-based telerehabilitation.
Leprosy among new child cases in China: Epidemiological and clinical analysis from 2011 to 2020
Authors: Peng Jiayi , Sun Peiwen , Wang Le , Wang Hongsheng , Long Siyu , Yu Mei-Wen
Published: February 2023

Background

Leprosy, caused by Mycobacterium leprae infection, mainly affects skin and peripheral nerves and may further lead to disability and deformity if not treated timely. The new case detection rate of leprosy in children reflects the active transmission of leprosy infection. This study aims to present the epidemiology and clinical characteristics of new leprosy cases in children in China from 2011 to 2020.

Methodology/Principal findings

All data from leprosy patients younger than 15 years old were extracted from the Leprosy Management Information System in China (LEPMIS). Statistical Package for the Social Sciences (SPSS) version 12.0 was used for descriptive and analytical statistics of the epidemiological and clinical indicators by the Mann-Whitney test, Kruskal-Wallis test, and Fisher’s exact test. And geographical distribution was analyzed by ArcGIS 10.5. A total of 152 pediatric new cases of leprosy were found over the last decade. The new case detection rate of pediatric leprosy cases decreased from 0.13 to 0.02 per 1,000,000 population over the last ten years. New pediatric cases had a higher new case detection rate in Guizhou, Sichuan, and Yunnan Provinces. All but 7 provinces in China achieved zero new child case for consecutive five years. The onset of leprosy peaked between 10 and 14 years of age, and the male to female ratio was 1.71:1. Pediatric patients were predominantly infected from symptomatic household adult contacts HHCs. Multibacillary leprosy (MB) was the most common. However, a low proportion of patients developed leprosy reaction and grade 2 disability.

Conclusions/Significance

The new case detection rate of pediatric leprosy cases has decreased over the past ten years in China. Spatial analysis indicated clusters in high-endemic areas. Leprosy transmission has stopped in the majority of provinces in China. However, sporadic cases may continue to exist for a long time. Active surveillance especially contact tracing should be focused on in future plan for management of leprosy, and interventions in leprosy clusters should be prioritized.
Study of Camellia sinensis diploid and triploid leaf development mechanism based on transcriptome and leaf characteristics
Authors: Yao Xinzhuan , Qi Yong , Chen Hufang , Zhang Baohui , Chen Zhengwu , Lu Litang
Published: February 2023

Polyploidization results in significant changes in the morphology and physiology of plants, with increased growth rate and genetic gains as the number of chromosomes increases. In this study, the leaf functional traits, photosynthetic characteristics, leaf cell structure and transcriptome of Camellia sinensis were analyzed. The results showed that triploid tea had a significant growth advantage over diploid tea, the leaf area was 59.81% larger, and the photosynthetic capacity was greater. The morphological structure of triploid leaves was significantly different, the xylem of the veins was more developed, the cell gap between the palisade tissue and the sponge tissue was larger and the stomata of the triploid leaves were also larger. Transcriptome sequencing analysis revealed that in triploid tea, the changes in leaf morphology and physiological characteristics were affected by the expression of certain key regulatory genes. We identified a large number of genes that may play important roles in leaf development, especially genes involved in photosynthesis, cell division, hormone synthesis and stomata development. This research will enhance our understanding of the molecular mechanism underlying tea and stomata development and provide a basis for molecular breeding of high-quality and high-yield tea varieties.

Authors: Brégère Catherine , Fisch Urs , Halbeisen Florian Samuel , Schneider Christian , Dittmar Tanja , Stricker Sarah , Aghlmandi Soheila , Guzman Raphael
Published: February 2023

Objective

Doublecortin (DCX) and glypican-2 (GPC2) are neurodevelopmental proteins involved in the differentiation of neural stem/progenitor cells (NSPCs) to neurons, and are developmentally downregulated in neurons after birth. In this study, we investigated whether the concentrations of DCX and GPC2 in the cerebrospinal fluid (CSF) from human pediatric patients reflect this developmental process or are associated with cerebral damage or inflammatory markers.

Methods

CSF was collected from pediatric patients requiring neurosurgical treatment. The concentrations of DCX, GPC2, neuron-specific enolase (NSE), S100 calcium-binding protein B (S100B), and cytokines (IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-13, IFN-γ, and TNF-⍺) were measured using immunoassays.

Results

From March 2013 until October 2018, 63 CSF samples were collected from 38 pediatric patients (20 females; 17 patients with repeated measurements); the median term born-adjusted age was 3.27 years [Q1: 0.31, Q3: 7.72]. The median concentration of DCX was 329 pg/ml [Q1: 192.5, Q3: 1179.6] and that of GPC2 was 26 pg/ml [Q1: 13.25, Q3: 149.25]. DCX and GPC2 concentrations independently significantly associated with age, and their concentration declined with advancing age, reaching undetectable levels at 0.3 years for DCX, and plateauing at 1.5 years for GPC2. Both DCX and GPC2 associated with hydrocephalus, NSE, IL-1β, IL-2, IL-8, IL-13. No relationship was found between sex, acute infection, S100B, IL-4, IL-6, IL-10, IFN-γ, TNF-α and DCX or GPC2, respectively.

Conclusions

Concentrations of DCX and GPC2 in the CSF from pediatric patients are developmentally downregulated, with the highest concentrations measured at the earliest adjusted age, and reflect a neurodevelopmental stage rather than a particular disease state.

Published: February 2023

The purpose of this work is to present a computer assisted diagnostic tool for radiologists in their diagnosis of Alzheimer’s disease. A statistical likelihood-ratio procedure from signal detection theory was implemented in the detection of Alzheimer’s disease. The probability density functions of the likelihood ratio were constructed by using medial temporal lobe (MTL) volumes of patients with Alzheimer’s disease (AD) and normal controls (NC). The volumes of MTL as well as other anatomical regions of the brains were calculated by the FreeSurfer software using T1 weighted MRI images. The MRI images of AD and NC were downloaded from the database of Alzheimer’s disease neuroimaging initiative (ADNI). A separate dataset of minimal interval resonance imaging in Alzheimer’s disease (MIRIAD) was used for diagnostic testing. A sensitivity of 89.1% and specificity of 87.0% were achieved for the MIRIAD dataset which are better than the 85% sensitivity and specificity achieved by the best radiologists without input of other patient information.

Published: February 2023

Advances in wound treatment depend on the availability of animal models that reflect key aspects of human wound healing physiology. To this date, the accepted mouse models do not reflect defects in the healing process for chronic wounds that are associated with type two diabetic skin ulcers. The long term, systemic physiologic stress that occurs in middle aged or older Type 2 diabetes patients is difficult to simulate in preclinical animal model. We have strived to incorporate the essential elements of this stress in a manageable mouse model: long term metabolic stress from obesity to include the effects of middle age and thereafter onset of diabetes. At six-weeks age, male C57BL/6 mice were separated into groups fed a chow and High-Fat Diet for 0.5, 3, and 6 months. Treatment groups included long term, obesity stressed mice with induction of diabetes by streptozotocin at 5 months, and further physiologic evaluation at 8 months old. We show that this model results in a severe metabolic phenotype with insulin resistance and glucose intolerance associated with obesity and, more importantly, skin changes. The phenotype of this older age mouse model included a transcriptional signature of gene expression in skin that overlapped that observed with elderly patients who develop diabetic foot ulcers. We believe this unique old age phenotype contrasts with current mice models with induced diabetes.

Published: February 2023

When people leave correctional institutions, they face myriad personal, social and structural barriers to reentry, including significant challenges with mental health, substance use, and homelessness. However, there are few reentry programs designed to support people’s health, wellbeing, and social integration, and there are even fewer evaluations of such programs. The purpose of this article is to report the qualitative findings from an early process evaluation of the Reintegration Centre—a peer-led service hub designed to support men on the day they are released from custody. We conducted semi-structured qualitative interviews and examined quantitative service intake data with 21 men who accessed the Reintegration Centre immediately upon release. Participants encountered significant reentry challenges and barriers to service access and utilization. The data suggest that the peer-led service hub model enhanced the service encounter experience and efficiently and effectively addressed reentry needs through the provision of basic supports and individualized service referrals. Notably, the Reintegration Centre’s proximity to the detention centre facilitated rapid access to essential services upon release, and the peer-support workers affirmed client autonomy and moral worth in the service encounter, fostering mutual respect and trust. Locating reentry programs near bail courts and detention centres may reduce barriers to service access. A peer-led service hub that provides immediate support for basic needs along with individualized service referrals is a promising approach to reentry programs that aim to support post-release health, wellbeing, and social integration. A social system that fosters cross-sectoral collaboration and continuity of care through innovative funding initiatives is vital to the effectiveness and sustainability of such reentry programs.

O turismo de cassinos é o tema da presente investigação, cujo recorte espacial contempla a região do Destino Turístico Iguaçu, na tríplice fronteira entre Brasil, Paraguai e Argentina, que oferta jogos de apostas como um de seus produtos. A pesquisa contribui para reduzir uma lacuna existente na literatura sobre turismo de cassinos no Brasil, buscando entender as motivações dos fluxos para estes atrativos a partir da perspectiva do turista. O objetivo geral é identificar os fatores motivacionais que levam os turistas brasileiros a visitar os cassinos do Destino Turístico Iguaçu. A metodologia utilizada foi de natureza qualitativa e documental tendo como fonte de dados comentários de turistas na plataforma TripAdvisor. A captura dos comentários ocorreu com o uso de um software em Python, obtendo-se uma amostra de 2.197 comentários em língua portuguesa, entre agosto de 2012 e março de 2020. A tabulação e o processamento dos dados foram realizados com mecanismos para análise de textos do software R, que gerou um conjunto de quadrigramas (sequências de quatro palavras), para catalogar os fatores motivacionais que emergiram do corpus analisado. Aplicando análise de conteúdo, os quadrigramas foram classificados nas categorias motivacionais do modelo bidimensional push e pull proposta por Dann (1977) e Crompton (1979). Observou-se que as motivações que mais incentivam o turista a frequentar os cassinos (push) se concentram nos fatores “novidade”, seguido de “socialização” e “repouso e relaxamento”. No que tange às características que atraem os turistas para os cassinos (pull) aparecem os fatores “infraestrutura”, seguido de “bares e entretenimento” e “acomodações e transporte”.

Due to the localized heavy rains in the metropolitan area in 2022, many lives and property damages occured. As such, climate change and urbanization intensifying damage from natural disaster. and it is urgent to improve the response system for disasters. In the case of the implementation of the existing disaster prevention project, the lack of standardized technology in all stages causes a lack of consistency in design and construction, an increase in construction cost, and a decrease in construction quality. Therefore, in this study, a standard and integrated management system was developed for disaster prevention project management. As a research method, the Marmi-Ⅲ methodology among CBD methodologies was used. By analyzing system requirements, we developed an appropriate business model selection module, outline construction cost calculation module, and project priority calculation module, and developed a management system that integrates each module with the GIS engine. It is expected to be able to increase the speed and work efficiency of project management for flood prevention through using this system.

Failing Young and Temporary Workers? The Impact of a Disruptive Crisis on a Dual Labour Market
Authors: Nunes Carolina , Carvalho Bruno P. , Pereira dos Santos João , Peralta Susana , Tavares José
Published: February 2023

We study the impact of the pandemic crisis using monthly data covering the universe of individuals registered as unemployed in mainland Portuguese municipalities, complemented with electronic payments, linked employer–employee data, and furlough records. Event study designs identify a sharp increase in unemployment, driven mostly by termination of temporary contracts, and a decrease in new job placements. With triple difference-in-differences, we show that the effects are stronger in more dual municipal labour markets, i.e. with a higher share of temporary jobs, concentrated in young workers and middle educated individuals. The asymmetries are exacerbated by the duality of the municipal labour market.
An improved multi-source domain adaptation network for inter-subject mental fatigue detection based on DANN
Authors: Chen Kun , Liu Zhiyong , Li Zhilei , Liu Quan , Ai Qingsong , Ma Li
Published: February 2023

Objectives

Electroencephalogram (EEG) is often used to detect mental fatigue because of its real-time characteristic and objective nature. However, because of the individual variability of EEG among different individuals, tedious and time-consuming calibration sessions are needed.

Methods

Therefore, we propose a multi-source domain adaptation network for inter-subject mental fatigue detection named FLDANN, which is short for focal loss based domain-adversarial training of neural network. As for mental state feature extraction, power spectrum density is extracted based on the Welch method from four sub-bands of EEG signals. The features of the source domain and target domain are fed into the FLDANN network. The contributions of FLDANN include: (1) It uses the idea of adversarial to reduce feature differences between the source and target domain. (2) A loss function named focal loss is used to assign weights to source and target domain samples

Results

The experiment result shows that when the number of the source domains increases, the classification accuracy of domain-adversarial training of neural network (DANN) gradually decreases and finally tends to be stable. The proposed method achieves an accuracy of 84.10% ± 8.75% on the SEED-VIG dataset and 65.42% ± 7.47% on the self-designed dataset. In addition, the proposed method is compared with other domain adaptation methods and the results show that the proposed method outperforms those state-of-the-art methods.

Conclusions

The result proves that the proposed method is able to solve the problem of individual differences across subjects and to solve the problem of low classification performance of multi-source domain transfer learning.

Polycrystalline ZnSe thin films with thickness 720 nm were prepared by thermal evaporation under ultra vacuum onto glass substrates. The optical properties of the as deposited and UV-irradiated films with different exposure times (0, 30, 60, 90, and 120 min.) were reported. The polycrystalline nature of the films was detected by XRD measurements. XRD patterns for UV irradiated films show that the intensities of the peaks increase with increasing the UV-irradiated time but the full width at half maximum (FWHM) decreases. The optical constants of the films were calculated by Swanepoel's method in terms of wedge shape model to obtain both thickness and refractive index with high precision. The energy gap of ZnSe films was determined by using the transmission in terms of transmission spectra in the strong absorption region. In terms of the obtained results, the increase of exposure time improved shrinkage of non-uniform transmission in both the strong and medium absorption region of ZnSe film. The optimal improvement was at UV-irradiation time equal 120 min. Accordingly, the possibility of asserting that such tenability in the optical refractive index and energy gap of ZnSe thin films with UVirradiation serves as a promising film in optoelectronic devices.

We demonstrated Q-switched and soliton mode-locked pulses operating at 1569.51 nm and 1564.45 nm, respectively by using a newly developed Bismuth Telluride Polyvinyl Alcohol (Bi2Te3 PVA) film as saturable absorber (SA). By incorporating the SA into an Erbium-doped fiber laser (EDFL) cavity, Q-switched pulses were obtained within a pump power range from 101.90 to 175.82 mW. At the maximum pump power, the laser operated at repetition rate of 92.76 kHz and pulse width of 4.76 µs while producing the highest single pulse energy of 39.4 nJ. By incorporating an additional 200 m long single-mode fiber into the laser cavity, stable soliton mode-locked pulses were generated. It operated at repetition rate of 0.97 MHz with a pulse width of 2.97 ps and a signal-to-noise ratio (SNR) of 50.89 dB.

Time-frequency analyses applied to sound brought about by continual impacts for time-varying axial stress measurement of round bar
Authors: Yoshida Tsutomu , Aoki Sunao
Published: February 2023

We developed the method to measure a time-varying stress of a round bar by time-frequency analyses. The larger tension we give to a guitar string, the higher tone the string emits, i.e. the string is changing its natural frequency to be higher. The frequency of the string is a function of the tension. When we look at the relation conversely, we can estimate tension by the frequency. We conceived the idea that if we could measure the variation of the frequency, we would be able to evaluate how the tension varied with time. The same condition holds for a round bar. We are able to estimate the time-varying axial stress of the bar by measuring the variation of the natural frequency of the bar. In order to verify of this idea, we conducted the experiment. We applied a sinusoidal stress to the bar. We gave continual impacts to the bar to bring about free vibrations. The vibrations produce sound. The sound provides data to follow the variation of the natural frequency. The procedure which consisted of a short-time Fourier transform application and signal processing programs we developed was applied to the sound. We could obtain the sequence of points which described the relation between the first mode natural frequency of the bar and time. We converted the sequence of the frequency to the sequence of the axial stress employing the relation between the natural frequency and the axial stress of the bar. We compared the stress sequence estimated by the procedure with the stress variation measured by the strain gauge attached to the bar. The sequences by the procedure and the variation by the strain gauge agreed well for various sinusoidal applied stresses for the loading cycle of less than 10 Hz.
Discourse of masculinity in Ivan Franko’s prose
Authors:   Ivan Franko Institute of the National Academy of Sciences of Ukraine, Shmeha Kateryna
Published: February 2023

The book deals with masculine discourse in Ivan Franko’s prose. Special attention is focused on such issues of the masculine discourse as power, professional and public realization of men, parent-filial relations, violence, alcoholism, etc., which were relevant to the Franko’s period and remain so today. After all, from this perspective the character images, the character-forming principles of the writer, the manifestations of masculine identity, axiology and the ways of male socio-integration are revealed more detail. The discourse of masculinity is analyzed in the context of Galicia in the late 19th – early 20th century and taking into account the elements of autobiography. It is concluded that changing of Galicia’s social system in the 19th century, with its rapid urbanization and cultural conservatism, forced men to acquire new social roles and professions, attaining masculine features related to the specifics of their chosen activities. On this basis, masculine types such as “reformer”, “rebel”, “business man”, “wasted man” and others are distinguished. It is determined that Franko’s works on a plot level correlate with mythic stories, which refer to a hero-civilizator – a cultural hero, and such a character is close to writer’s masculine ideal. The collective image of a cultural hero is most fully represented in the image of Kost’ Dumiak (The Great Noise), a fearless, prudent, wise, self-confident person, but not only engaged in the public service, a happy husband and father. A particular chapter of the book is focused on the strategies and tactics of men’s communication, their verbal and non-verbal communication behavior. Special attention is payed at describing of male physicality. Ivan Franko does not shy away from portraying a sick, frail, old body, yet he cultivates images of healthy, developed, not too thin, but also not obese, mature or even older men. The leitmotif attributes of the masculine appeal of his characters are moustaches, wide shoulders and high height, activity and confidence of movements, lively look. The interdependence of a healthy body and a healthy spirit is inherent for visual characteristic of images. The book will be useful for everyone interested in gender as one of the literary categories, as well as the discourse of masculinity in Ukrainian literature and in the works of Ivan Franko.

No Brasil, a formulação da política de defeso não leva em conta o conhecimento tradicional, que é, via de regra, marginalizado e não reconhecido perante às políticas públicas que as atingem. Nesse sentido, encontramos uma marcada incompatibilidade entre o conhecimento de pescadores artesanais do estuário do rio Itapicuru, norte da Bahia, sobre o período reprodutivo de alguns animais marinhos, e seus atuais defesos. Levando-se em conta esse tipo de conhecimento, é nítido que duas espécies de robalo, bem como quatro espécies de camarão estão sendo protegidas na época errada. Portanto, propomos a revisão das legislações pertinentes levando-se em conta o conhecimento de especialistas tradicionais, bem como em futuras políticas de defeso. Para alcançar uma compreensão mais robusta e precisa da situação propomos integrar o conhecimento científico acadêmico ao conhecimento tradicional em uma abordagem de pesquisa participativa. Para que políticas de conservação tenham efeitos tangíveis, devemos combinar estudos científicos rigorosos com esforços etnográficos a fim de trazer o conhecimento de especialistas tradicionais sobre os períodos reprodutivos das espécies, que por sua vez podem variar significativamente para uma mesma espécie de acordo com sua distribuição geográfica. Este resultado mostra como a integração ou coprodução do conhecimento não só permite melhorar as práticas de gestão ambiental e formulação de políticas públicas, mas também pode desempenhar um papel de empoderamento para comunidades tradicionais e povos indígenas, contribuindo para suas autodeterminações.

Introduction. The Amazon region has a great plant diversity, but studies on their propagation and growth have been carried out in few species. Objective. To evaluate the in situ and ex situ germination of Sterculia colombiana and its growth characteristics after planting in ground covers of primary forest and intervened areas. Materials and methods. The study was carried out in Napo, Ecuador, in the period 2019-2020. The germination of S. colombiana was characterized in the variables: days and percentage to emergence, plant height, stem diameter and number of leaves, under greenhouse conditions and planted at the collection site. The plants obtained in the germination test were transplanted to a ground cover of primary forest (in situ) and an intervened area with replacement vegetation (ex situ). Linear, quadratic, cubic, exponential, and logarithmic growth models for stem height and diameter were evaluated. The air and soil temperature and the physical-chemical characteristics of the soil were recorded. An analysis of variance was performed to determine differences in growth and survival between the plantation sites and between the plants obtained in the in situ and ex situ tests. Results. The seedlings obtained from greenhouses reported fewer days to emergence and higher values in the rest of the variables evaluated than those grown in situ. The plants developed in the different evaluated covers, without significant differences in growth at the end of the study, only a significant correlation at 5 % between stem diameter and air temperature was reported. Conclusions. Sterculia colombiana germinated in a greenhouse and developed in the transplant sites, without this influencing its growth. Temperature was the only factor that reported significant correlations with growth at the end of the evaluation period.
