Authors: Bieszk-Stolorz Beata , Dmytrów Krzysztof
Published: September 2023

The goal of this research is a static geographic comparison of the degree of Sustainable Development Goal 8 (SDG8) implementation and to compare its dynamics for the European Union (EU) in the period of 2002–2021 with the consideration of the COVID-19 pandemic. The level of implementation of the 2030 Agenda for Sustainable Development objectives is monitored both jointly and individually. This research uses the COPRAS, the Dynamic Time Warping (DTW) and the hierarchical clustering methods. The study confirmed the geographical diversity in the degree of SDG8 implementation. Nordic countries have the highest degree of implementation, while Greece, Spain, Italy, Romania and Slovakia have the lowest. Some less-developed countries (Czechia, Poland and Malta) were in the cluster where the implementation improved, and some well-developed countries (France, Luxembourg and Portugal) were in the cluster in which the situation did not improve or improved at a low degree. It was not possible to identify geographical diversity in the dynamics of changes in the degree of SDG8 implementation. The COVID-19 pandemic caused the decline in the degree of SDG8 implementation. The added value of the study consists of comparing the dynamics of the degree of implementation of SDG8 using the DTW method. The obtained conclusions may help to create policies for EU countries in this regard.

Published: September 2023

This study takes 1597 key villages and towns part of rural tourism in China as research objects and uses the ArcGIS spatial analysis method, combined with the geodetector and the multiscale geographically weighted regression model, to analyze the intensity and spatial differentiation of factors influencing the spatial distribution of these villages and towns. (1) The key villages and towns of rural tourism exhibit clustering distribution patterns with more locations in the east than in the west. The center of gravity of this distribution shifts to the northwest, displaying a “belt–point” trend with scattered hot spots in Beijing, Tianjin, Hebei, and the Yangtze River Delta, while cold spots are primarily concentrated in the northwest. (2) Spatial variation in the key villages and towns of rural tourism is due to multiple factors, of which population density, resident consumption expenditure, and per capita GDP display the highest explanatory powers for the spatial distribution of tourism. (3) The primary influencing factors are spatial differences in their roles and substantial local imbalances. Positive and negative correlation analysis units exhibit the aggregation characteristics of being blocked and banded. These results can provide valuable guidance for the development of rural tourism, promoting its sustainable development and contributing to the revitalization of rural areas.

Published: September 2023

This research aims to examine the impact of COVID-19 on businesses operating in the tourism industry in the Azores. The objective of this survey, conducted in 2021 and 2022, was to investigate the preventive and management measures implemented by the tourist firms, in this outermost region of Portugal, in response to the pandemic, along with the effects on profitability. Additionally, the study aims to assess the contribution of financial support from the regional government toward these businesses’ sustainability and anticipate future expectations. The temporary closure of businesses was the most frequently adopted measure by the firms to adapt to the ongoing pandemic. Most companies reported a significant decline in profitability, with a reduction in customers being the primary contributing factor. Most firms availed themselves of the preceding financial support structures provided by the regional government. Looking forward, the firms expressed their intention to retain their current employees. At the same time, their biggest concern was the potential decrease in consumer demand, even in the context of well-established public health safety protocols.

Air pollution has become a global health issue, affecting millions of people annually. It is essential to obtain accurate and up-to-date information on air quality levels to reduce the impact of air pollution on human health. Traditional air quality monitoring methods are limited by spatial coverage and the time required for sample collection and analysis. However, the Internet of Things (IoT), drone technology, and Geographic Information System (GIS) technology have enabled the development of real-time air quality monitoring systems that provide accurate and up-to-date information on air quality levels across large areas. The study found that gas concentration varied significantly at different heights, with the highest concentration at 3 m from the ground and the lowest at 9 m. The concentration of gases also varied by month, with the highest concentration of CO recorded in March at 45 ppm at 3 m, and the highest concentration of NH4 recorded in September at 66.7 ppm at 3 m. Kodungaiyur dump yard needs environmental monitoring due to the high levels of environmental pollution and health risks caused by unsegregated waste. In conclusion, developing real-time air quality monitoring systems using GIS technology is necessary to obtain accurate and up-to-date information on air quality levels. It is essential to monitor the Kodungaiyur dump yard and other, similar sites regularly to prevent the health risks associated with environmental pollution.

Published: September 2023

In order to study the physical and mechanical properties of sandstone under high-temperature water-cooling cycling conditions, an RMT-150B electrohydraulic servo rock testing system and a DS-5 acoustic emission detection and analysis system were used to conduct uniaxial compression acoustic emission tests on sandstone after high-temperature water-cooling cycles. The deformation, strength, and acoustic emission characteristics of sandstone were analyzed under different temperatures and cycle times. The results show that the high-temperature water-cooling effect caused changes in the physical properties of sandstone. The volumetric expansion rate of the rock samples first decreased, then increased in temperature, and the strength first increased, then decreased, whereas the number of cycles had less of an impact on the physical properties. At 200 °C, with increased cycle number, the elastic modulus increased by 20.1%, and the compressive strength increased from 63.9 MPa to 71.46 MPa. At 300–600 °C, the elastic modulus and compressive strength of sandstone gradually decreased with increases in the temperature and cycle number, with reductions of 6.04%, 7.24%, 28.7%, 35.57%, 17.6%, 18.2%, 20.4%, and 60.5%, respectively. With increased temperature and cycle times, the acoustic emission ringing counts increased, ringing counts and cumulative energy appeared earlier, the rock samples entered elastic deformation earlier, the yield stage length increased, and the samples showed a tendency to transition from brittle to ductile damage.

Published: September 2023

The independent metering system used in the combination of traditional cartridge proportional valves employs an excessive number of components, which increases the complexity of the control strategy. To address this problem, a novel independent metering system based on pilot hydraulic control was developed. Following the pressure and flow requirements, the structure and valve body size of the two spools were designed. The effect of the parameter change in the control valve on the dynamic response characteristics of the main spool was investigated by simulation. A control strategy was developed based on load force direction prediction and two-chamber pressure switching to verify the feasibility of working mode switching during load direction change. As indicated by the results, compared with the mode switching control strategy of the traditional independent metering system, the proposed control strategy could effectively reduce the number of mode switching and ensure the continuity of the actuator operation. Compared with the traditional load-sensitive valve control system, the proposed pilot-controlled independent metering system achieved an average energy-saving efficiency of 47.27%. This study provides technical reference for the low energy consumption, high efficiency, and sustainable development of hydraulic systems.
Sustainability of a Rainfed Wheat Production System in Relation to Water and Nitrogen Dynamics in the Soil in the Eyre Peninsula, South Australia

Published: September 2023

Rainfed wheat production systems are usually characterized by low-fertility soils and frequent droughts, creating an unfavorable environment for sustainable crop production. In this study, we used a processed-based biophysical numerical model to evaluate the water balance and nitrogen (N) dynamics in soils under rainfed wheat cultivation at low (219 mm, Pygery) and medium rainfall (392 mm, Yeelanna) sites in south Australia over the two seasons. Estimated evapotranspiration components and N partitioning data were used to calibrate and validate the model and to compute wheat’s water and N use efficiency. There was a large disparity in the estimated water balance components at the two sites. Plant water uptake accounted for 40–50% of rainfall, more at the low rainfall site. In contrast, leaching losses of up to 25% of seasonal rainfall at the medium rainfall site (Yeelanna) indicate a significant amount of water evading the root zone. The model-predicted N partitioning revealed that ammonia–nitrogen (NH4–N) contributed little to plant N nutrition, and its concentration in the soil remained below 2 ppm throughout the crop season except immediately after the NH4–N-based fertilizer application. Nitrate–nitrogen (NO3–N) contributed to most N uptake during both seasons at both locations. The N losses from the soil at the medium rainfall site (3.5–20.5 kg ha−1) were mainly attributed to NH4–N volatilization (Nv) and NO3–N leaching (NL) below the crop root zone. Water productivity (8–40 kg ha−1 mm−1) and N use efficiency (31–41 kg kg−1) showed immense variability induced by climate, water availability, and N dynamics in the soil. These results suggest that combining water balance and N modeling can help manage N applications to optimize wheat production and minimize N losses in rainfed agriculture.
Large-Scale Asymmetry in the Distribution of Galaxy Spin Directions—Analysis and Reproduction
Authors: Shamir Lior
Published: September 2023

Recent independent observations using several different telescope systems and analysis methods have provided evidence of parity violation between the numbers of galaxies that spin in opposite directions. On the other hand, other studies argue that no parity violation can be identified. This paper provides detailed analysis, statistical inference, and reproduction of previous reports that show no preferred spin direction. Code and data used for the reproduction are publicly available. The results show that the data used in all of these studies agree with the observation of a preferred direction as observed from Earth. In some of these studies, the datasets were too small, or the statistical analysis was incomplete. In other papers, the results were impacted by experimental design decisions that led directly to showing nonpreferred direction. In some of these cases, these decisions were not stated in the papers but were revealed after further investigation in cases where the reproduction of the work did not match the results reported in the papers. These results show that the data used in all of these previous studies, in fact, agree with the contention that galaxies as observed from Earth have a preferred spin direction, and the distribution of galaxy spin directions as observed from Earth forms a cosmological-scale dipole axis. This study also shows that the reason for the observations is not necessarily an anomaly in the large-scale structure, and can also be related to internal structure of galaxies.
Evolutionary Game Analysis on Operation Mode Selection of Big-Science Infrastructures
Authors: Huang Zhenyu
Published: September 2023

As big-science infrastructures (BSIs) become the new infrastructure to support the construction of strong science and technology in China, how to choose an operation mode that is more conducive to achieving the construction goals of BSIs has become a current focus issue. The existing literature focuses more on the governance relationship between BSIs and universities or research institutes, while the important role of government has not yet been thoroughly analyzed. This study argues that government plays a fundamental role in the selection of operation modes for BSIs. Therefore, this study builds an evolutionary game model between the government and the contractor based on the perspective of asset specificity by analyzing the practical basis for the strategic choices of the government and the contractor for the operation of BSIs. The model is numerically simulated and analyzed. The research results indicate that the government’s decisions on operation strategies, outsourcing strategies, and the combination of the two significantly affect the strategic choices of the contractor, thereby affecting whether the government can obtain the value of asset specificity of BSIs. The government’s choice of the “independent operation” strategy or the combination “dependent operation + controlled outsourcing” strategy is more conducive to encouraging the contractor to choose the “cooperation” strategy for producing specific value for BSIs. The main contribution of this study is to clarify that the allocation of the government control right is the key factor in obtaining the value of asset specificity of BSIs.

Smoking cessation is difficult but maintaining smoke-free without nicotine replacement therapy is even harder. During the last few years, several different alternative products, including heated tobacco products (HTP), have been introduced to the market. In this study, we investigated the acute effects of IQOSTM and gloTM (two HTP) consumption on small airway function and arterial stiffness in a head-to-head design, comparing them to combustible cigarettes, nicotine-free e-cigarettes and a sham smoking group. Seventeen healthy occasional smokers were included in a single-center, five-arm, crossover study. The parameters of small airway function and hemodynamics were collected at several time points before and after consumption using Mobil-O-Graph™ (I.E.M., Stolberg, Germany) and TremoFlo® c-100 (THORASYS Thoracic Medical Systems Inc., Montreal, QC, Canada). Small airway obstruction and resistance were both significantly increased after the consumption of cigarettes and substitute products. All products containing nicotine led to similar significant increases in blood pressure and arterial stiffness. Hemodynamic parameters were also increased after the consumption of e-cigarettes without nicotine, but compared to nicotine-containing products, the increase was shorter and weaker. We conclude that, although it has yet to be determined why, HTP have acute harmful effects on small airway function, possibly even exceeding the effects of combustible cigarettes. Like other nicotine-containing products, HTP leads to a nicotine-related acute increase in arterial stiffness and cardiovascular stress, similar to combustible cigarettes, which associates these products with an increased cardiovascular risk.

Microplastics (MPs) have received a lot of attention and have been detected in multiple environmental matrices as a new environmental hazard, but studies on human internal exposure to MPs are limited. Here, we collected lung tissue samples from 12 nonsmoking patients to evaluate the characteristics of MPs in human lung tissues using an Agilent 8700 laser infrared imaging spectrometer and scanning electron microscopy. We detected 108 MPs covering 12 types in the lung tissue samples, with a median concentration of 2.19 particles/g. Most of the MPs (88.89%) were sized between 20 to 100 μm. Polypropylene accounts for 34.26% of the MPs in the lung tissues, followed by polyethylene terephthalate (21.30%) and polystyrene (8.33%). Compared with males and those living far from a major road (≥300 m), females and those living near the main road (<300 m) had higher levels of MPs in lung tissues, which positively correlated with platelet (PLT), thrombocytocrit, fibrinogen (FIB), and negatively related with direct bilirubin (DB). These findings help confirm the presence in the respiratory system and suggest the potential sources and health effects of inhaled MPs.
Plane Symmetric Cosmological Model with Strange Quark Matter in f(R,T) Gravity

Published: September 2023

A plane symmetric Bianchi-I model filled with strange quark matter (SQM) was explored in f(R,T)=R+2λT gravity, where R is the Ricci scalar, T is the trace of the energy-momentum tensor, and λ is an arbitrary constant. Three different types of solutions were obtained. In each model, comparisons of the outcomes in f(R,T) gravity and bag constant were made to comprehend their roles. The first power-law solution was obtained by assuming that the expansion scalar is proportional to the shear scalar. This solution was compared with a similar one obtained earlier. The second solution was derived by assuming a constant deceleration parameter q. This led to two solutions: one power-law and the other exponential. Just as in the case of general relativity, we can obtain solutions for each of the different eras of the universe, but we cannot obtain a model which shows transitional behavior from deceleration to acceleration. However, the third solution is a hybrid solution, which shows the required transition. The models start off with anisotropy, but are shear free at late times. In general relativity, the effect of SQM is to accelerate the universe, so we expect the same in f(R,T) gravity.

Published: September 2023

Introduction: Urinary incontinence is a prevalent condition, especially in elderly men, with stress urinary incontinence (SUI) being a common cause after radical prostatectomy. The artificial urinary sphincter (AUS), particularly the AMS 800™ device, has been the gold-standard treatment for moderate-severe male SUI for decades. Despite some technical advancements and alternative devices like ZSI-375, Victo, and BR-SL-AS 904 being introduced, there is limited literature comparing their effectiveness to the AMS 800™. Methods: This literature review compares the AMS 800™ to the newer technologies in the management of SUI. We reviewed the current literature on urinary sphincter implant in male stress incontinence, including AMS 800™, ZSI-375, Victo, and BR-SL-AS 904. Findings: The AMS 800™ is a sophisticated system consisting of an inflatable cuff, a pressure-regulating balloon, and a control pump. Studies show continence rates ranging from 61% to 100% with AMS 800™ implants, with low infection rates and significant improvement in patients’ quality of life. The ZSI-375 sphincter is a unique single-piece cuff without an abdominal reservoir, simplifying implantation. Preliminary data show a social continence rate of 73% at six months, with lower complication rates than the AMS 800™. The VICTO® device offers adjustable pressure and a stress relief mechanism, providing conditional occlusion of the urethra. Early studies report a satisfaction rate of up to 94.2% and a complication rate of 17.6%. BR-SL-AS 904 is a newly proposed urinary sphincter, but due to the limited number of cases and a single study, its efficacy and complication rates remain uncertain. Conclusions: Overall, AMS 800™ remains the gold-standard treatment for SUI after radical prostatectomy. Alternative devices like ZSI-375 and VICTO® show promising results, but longer studies and more data are needed to establish their effectiveness and safety compared with the AMS 800™. Further research and ongoing monitoring are essential to address mechanical issues associated with AUS implants.

The prevention and management of cytomegalovirus (CMV) reactivation is important to improve the outcomes of allogeneic hematopoietic cell transplantation (allo-HCT) recipients. The aim of this study was to analyze real-world data regarding the incidence and characteristics of CMV infections until 1 year after allo-HCT under 100-day letermovir prophylaxis. A single-center retrospective study was conducted between November 2020 and October 2021. During the study period, 358 patients underwent allo-HCT, 306 of whom received letermovir prophylaxis. Cumulative incidence of clinically significant CMV infection (CS-CMVi) was 11.4%, 31.7%, and 36.9% at 14 weeks, 24 weeks, and 1 year post-HCT, respectively. Through multivariate analysis, the risk of CS-CMVi increased with graft-versus-host disease (GVHD) ≥ grade 2 (adjusted odds ratio 3.640 [2.036–6.510]; p < 0.001). One-year non-relapse mortality was significantly higher in letermovir breakthrough CS-CMVi patients than those with subclinical CMV reactivation who continued receiving letermovir (p = 0.002). There were 18 (15.9%) refractory CMV infection cases in this study population. In summary, letermovir prophylaxis is effective at preventing CS-CMVi until day 100, which increased after the cessation of letermovir. GVHD is still a significant risk factor in the era of letermovir prophylaxis. Further research is needed to establish individualized management strategies, especially in patients with significant GVHD or letermovir breakthrough CS-CMVi.
Why Is Residential Irrigation So Hard to Optimize?
Authors: Sowby Robert B. , Lunstad Nathan T.
Published: September 2023

Irrigation of residential landscapes is one of the largest demands for municipal water suppliers. However, it is often done inefficiently and is a concern for limited capacity and low pressure. Why, really, is residential landscape irrigation so inefficient, and why is it so difficult to optimize? The problem, as we suggest framing it, comes down to four C’s: conditions, components, controls, and customers. The conditions for efficient irrigation are too complex, sprinkler components are too imprecise, sprinkler controls too simplistic, and most water customers are too untrained as irrigators. Any management system with so many weaknesses is sure to be inefficient. Better plant choices, better landscape layouts, and precision irrigation technology are obvious solutions. Beyond these solutions, we recommend further development of smart irrigation controllers that account for the complexity of irrigation conditions and allow remote control by the water supplier. For an incentive, owners can opt-in and occasionally have their irrigation delayed or skipped if the water supplier needs to shed demand. We call this an “integrated water distribution system” where one benefit is a discretionary water demand that can be coordinated between suppliers and customers.
Potential Use of Precipitates from Acid Mine Drainage (AMD) as Arsenic Adsorbents

Published: September 2023

The role of precipitates from acid mine drainage (AMD) in arsenic removal in water is a process to be investigated in more detail. The present study is focused on the potential use of two AMD precipitates using oxidation and Ca(OH)2 (OxPFe1) or CaCO3 (OxPFe2) as As(V) adsorbents and the comparison of their performance with two commercial adsorbents (nanohematite and Bayoxide®). The AMD’s supernatants and precipitates were characterized using several techniques and assessed with theoretical speciation and mass balance methods. Gypsum was identified by XRD and assessed as the main component of the precipitates. Amorphous iron hydroxide was assessed as the second component (22% in mass), and jurbanite or aluminum hydroxide were present in the third likely phase. The equilibrium adsorption of As(V) in water at a pH between 4 and 6 was tested with the four adsorbents, and the Langmuir model correlated well. The maximum adsorption capacity (qmax) had the highest value for OxPFe1 and the lowest value for nanohematite (that could be explained in terms of the adsorbent surface speciation). The two precipitates have limited application to the adsorption of very low concentrations of arsenic because they have a binding constant (b) lower than the commercial adsorbents and could release a small amount of the arsenic contained in the precipitate.

Probiotics and phytobiotics are a modern alternative to antibiotics in animal husbandry. Numerous studies confirm the effectiveness of probiotic additives in diets of pig, including improved growth rates, feed conversion effi ciency, modulation of the intestinal microbiota, nutrient utilization, intestinal health and regulation of the immune system. Probiotics have been proposed and used as the best alternative to the use of antibiotics as a remedy for diarrhea after weaning piglets and as growth stimulants. The purpose of the work was to study the reproductive traits of sows and the meat productivity of their off spring through the use of phytobiotic “Intebio” and probiotic “Profort” in the diets. In the fi rst scientifi c and economic experiment, the eff ect of the phytobiotic “Intebio” and the probiotic “Profort” on the reproductive traits of two-breed sows (F1) obtained as a result of crossbreeding sows of Yokshire breed with boars of Landrace breed, which were crossbred with boars of Duroc breed to obtain commercial young animals. In the second scientifi c and economic experiment, the effect of feed additives and their aftereff ect on the productive traits of the obtained three-breed off spring (F2) was studied. As a result of research to improve the reproductive traits of sows, increase the productivity of young animals and improve the quality of pork, we recommend using the phytobiotic “Intebio” in a dose of 120 g/t and the probiotic “Profort” in a dose of 500 g/t of feed according to the following scheme: for sows 30 days before farrowing and during the suckling period, for piglets from 7 to 105 days of rearing. The use of these additives will increase the prolificy of sows by 1,9–2,3 %, increase the livability of piglets by 4,0–6,1 abs.%, increase the absolute gain in live weight of young animals by 3,4–6,3 %.

The use of fertilizing for bees makes it possible to increase the productivity of bee colonies, replenish feed stocks in the hive in winter, and replace substandard fall honey collected in the autumn period. The purpose of the research was to study the effect of sugar-honey dough (candi) containing organic acids on the livability of bee colonies in winter, physiological parameters, intensity of development and their economically useful traits. Research and experimental work with bee colonies were carried out at the apiary of the Small innovative enterprise “Zhivprom” (Krasnodar). The use of liquid feed concentrate “Furor” in a ratio of 1:1 with granulated sugar had a positive effect on the bees’ body and contributed to an increase in the longevity of individuals in experimental cages by 9–10 days compared with the consumption of concentrate with granulated sugar by bees 2:1. The productivity of bees of the 3rd experimental group in 2019 was higher compared to the 1st and 2nd experimental groups at 5,5–5,8 kg, with the control group – at 17,1 kg. In 2020 commercial honey from the 3rd experimental group was obtained on average 61,1 kg, which was 5,5–7,1 kg more than in the 1st and 2nd experimental groups and 18 kg more than in the control group. The amount of commercial honey from bee colonies in 2021 in the 3rd experimental group was 68,1 kg. This indicator was higher than the 1st and 2nd experimental groups by 9,1–8,9 kg, and compared with the control group by 19 kg. The economic eff ect of using innovative top dressing was additionally from one bee family in 2019 – 2625,98 thousand rubles, in 2020 – 2769,98 thousand rubles, in 2021 – 3031,94 thousand rubles.

Economic relations of the last 30 years are characterized by a number of features, among which is digitalization. According to researchers, with all the abundance of definitions of this phenomenon, its main features can be called total computerization and widespread use of the Internet. The technologization of economic activity (electronic document management, online meeting format, computerization of marketing using CRM systems and similar programs) changes the very nature of this activity, making it more flexible and transparent, partially reducing the importance of the human factor. The concentration of actions and communication on the Internet allows us to talk about the formation of the principles of self-government in the network space. The author of this study set as his goal to test the hypothesis about the existence of legal customs that regulate certain economic processes in the context of digitalization.

Published: September 2023

This paper researches the opportunities and challenges of cross-border e-commerce development between Russia and China under the One Belt One Road initiative. Using SWOT analysis and official data, introduce the strengths, weaknesses, opportunities as well as threats of cross-border e-commerce development between Russia and China. The conclusion is that the current e-commerce market in China and Russia has great potential and has become a new growth point for foreign trade promotion and economic recovery, and its development has the strengths of political support and complementary product trade structures in both countries. In addition, the Belt and Road Initiative promotes the development of logistics infrastructure, an the rapid development of Internet technology and online trade provides opportunities for the development of e-commerce in China and Russia. However, in the current complex international situation, the development of cross-border e-commerce in both countries faces threats and challenges, such as the slow global economic recovery after the epidemic and the sanctions imposed on the Russian economy by Europe and the US. There are also its own weaknesses: imperfect cross-border payment and credit systems, limited trade models on the platform, and untimely logistics and delivery. Therefore, optimization and improvement of platforms, cross-border payments and cross-border logistics are needed. This study will contribute to enterprises exploring new paths for their own development, and optimizing the foreign trade structure of China and Russia as well as economic recovery.

A organização Meteorológica Mundial (OMM) preconiza que as mudanças climáticas e os eventos climáticos cada vez mais extremos causaram um aumento nos desastres naturais nos últimos 50 anos. Entre os desastres naturais, destaca-se a inundação de áreas urbanas e rurais brasileiras, causando graves prejuízos materiais a população e em alguns casos extremos levando a perdas socioeconômicas. Nesse contexto, a bacia hidrográfica do rio Tapacurá (BHRT) apresenta relevante importância para a região metropolitana da cidade do Recife, bem como para os municípios que estão contidos na área da bacia. Na década de 70 foi construída a barragem do Tapacurá com o intuito de diminuir as enchentes e inundações em períodos de chuvas intensas nas áreas de cabeceira da bacia, bem como em épocas de escassez das chuvas, servir para o abastecimento humano da região. O objetivo deste estudo foi identificar as áreas de risco de inundação da BHRT através da metodologia AHP (Analytic Hierarchy Process) utilizando cenas de radar da missão SRTM e mosaico de imagens de sensor óptico Landsat 8. A modelagem digital foi realizada no módulo HYDROLOGY do software ArcGIS da ESRI GIS and Mapping Software, licenciado para o Laboratório de Geotecnologias da UFRPE. Para verificar a consistência dos pesos estatísticos utilizados no método AHP, foi verificado a razão de consistência (RC), sendo este parâmetro menor que 0,1 para validação do modelo. Verificou-se que o nível de altíssimo risco de inundação da BHRT estão compreendidas nas áreas com menor altitude e baixa declividade da bacia, bem como nas áreas próximas a corpos dágua, com presença de solos mal drenados e baixo escoamento superficial.

A morte do chamado “pai primevo” por sua própria prole é a alegoria central da obra “Totem e Tabu”, publicada em 1913 por Freud.  Nesta obra, tem-se a tese da figura paterna que simbolicamente é destruída brutalmente por seu próprio clã, algo que reverbera fortemente nos aspectos religiosos. Com base nisso, este estudo tem por objetivo discutir sobre as relações que Freud trouxe sobre os rituais religiosos e os povo primitivos, especificamente sobre a eucaristia católica, que é um ritual simbólico em que os fiéis comungam “o corpo e o sangue de Jesus Cristo”, e expiam suas culpas e erros, pedindo redenção por sua morte que, segundo a tradição católica, foi crucificado pelos Judeus. Diante disso, esse ato pode ser visto como um simulacro fiel do parricídio e o prosseguinte “banquete totêmico”, descritos na mencionada obra freudiana.
The Combined Use of Predictors and Taylor Series in Nonlinear Interdependent Systems
Authors: Edgerton David
Published: September 2023

This article highlights some of the main points in the author’s doctoral thesis [7]. To be able to present a fairly comprehensive survey many points are only briefly mentioned here, while receiving considerable attention in the thesis. In particular the problem of identities and convergence criteria for the Fix-Point method are both discussed in detail in [7], where one can also find the proofs of various results which are merely stated here. It is hoped, however, that the main theme of the thesis, the reformulation and use of Taylor expansions in nonlinear systems, is brought out with sufficient clarity.

A Parotidite Recorrente Juvenil (PRJ) é uma manifestação clínica rara, que pode ter diversas causas. A PRJ é definida por episódios recorrentes de inflamação parotídea não obstrutiva, de fisiopatologia desconhecida. Existe maior número de relatos no gênero masculino, mas a incidência e a prevalência desse problema são desconhecidas. Este estudo tem o propósito de descrever a evolução de um caso de PRJ com acompanhamento em médio prazo e examinar os achados de exames de imagem e exames bioquímicos, além de realizar uma revisão de literatura sobre o tema. Evidenciou-se que o tratamento conservador à base de antinflamatórios e acompanhamento do paciente são eficazes para resolução a médio e longo prazo. Avaliação de enzimas salivares, bem como exame ultrassonográfico são suficientes para estabelecimento de diagnóstico correto.

Smart Village Concept: What are the Crucial Categories of Elements?
Authors: Głębocki Konrad
Published: September 2023

Over the past few decades, villages have faced significant challenges, such as depopulation, that have hindered their development. To address these issues, the concept of a Smart Village has emerged as a potential solution for rural development. The present article aims to investigate the essential categories of elements that comprise this concept by conducting an international literature review in multiple languages, including Polish, English, Spanish, Italian, French, and German. The article begins with an introduction that discusses the current challenges facing rural development, followed by a detailed analysis of various aspects of the Smart Village concept. Additionally, the article presents case studies from different countries to illustrate how the concept has been implemented in practice. Finally, the article employs inductive reasoning based on the previous literature review to identify four fundamental categories of elements that underpin the Smart Village concept.
Innovational Leadership and Knowledge Sharing: The Mediator Role of Self-efficacy
Authors: Castaneda Delio Ignacio , Ramirez Camilo
Published: September 2023

Abstract: Innovational leadership is a set of practices and skills that leaders develop to promote innovative behaviors in their workers at the individual and collective levels. This is a novel concept focused on one role of leaders: the facilitation of the generation of new or significantly improved products and services. Previous studies with other styles of leadership have shown that transformational leadership encourages a climate for innovative work behaviors, while transactional leadership influences exploitative innovation activities. Knowledge sharing involves the transfer of experience and expertise to facilitate business development and the accomplishment of organizational objectives. Self-efficacy is an individual´s confidence in their abilities to execute a particular task. It influences learning and performance. This research studied whether innovational leadership influences two types of knowledge sharing: tacit and explicit. At the same time, the role of self-efficacy as a mediator variable was evaluated. The sample consisted of 415 workers from different sectors in Colombia. According to the results, innovational leadership positively influenced tacit and explicit knowledge, although the effect on tacit knowledge was higher. Finally, self-efficacy played a mediator role in the relationship between innovational leadership and knowledge sharing. Additional research is suggested to explore the differences between innovational leadership and other types of leadership in the process of sharing tacit and explicit knowledge. At the same time, complementary investigations about the dynamics of innovational leadership are needed to understand why it affects more tacit knowledge than explicit knowledge.
Remote work and human resources challenges from the Covid-19 pandemic scenario: The cases of Italy and Portugal

This study presents the preliminary results of a European project (EURECA) being carried out in Italy and Portugal. One of its aims is to understand the role of remote work arising from the recent pandemic. The question that drove this research was: What is the role of remote work resulting from the emergent changes of the 2019 pandemic scenario in Portuguese and Italian organisations?. Case studies were used as the methodological approach, and the qualitative and inductive work directed the research, guided by the assumptions of practice-based theory. Thus, interviews were conducted with human resource managers and/or directors of companies/public institutions. So far, the sample comprises 16 organisations. The results show that before the crisis, which lasted about two years, most organisations did not engage in remote work. Afterwards, human resources practices had to adapt to this new reality, and hybrid work (a combination of remote and face-to-face work) is currently present in most of the organisations studied. New challenges are also appearing in this area, including new information systems, career management, and training and performance evaluation, among others. Hence, this new model of work design also brings new challenges to organisations and management. The implications pressing issue are several: practical (for management and organisations); theoretical (new inputs on HR practices, remote working and change management); and methodological (reinforcing the importance of case studies and practice-based theory in a comparative analysis of the Portuguese and Italian contexts). Avenues for further research are also proposed.
Relationships between leaders, capital, and knowledge

Published: September 2023

Intellectual capital describes the knowledge resources that a company can use to reap advantages (Muslih, 2021). While human capital is frequently associated with organizational capital (Beltramino, 2020), it is also important to emphasize the role of humans in generating intellectual capital (Dessein& Pratt, 2022; Ozgun, 2022). Interactions between employees within the organization or between its employees and their larger context are crucial. Such relationships have been described as "relational capital" (Zhang, 2022).  By one definition, leadership is the ability to influence people to achieve organizational goals (Daft, 2014). There is increasing recognition, however, that traditional leadership models are insufficient to face the challenges of a modern, turbulent world and must be transformed (Brennan, 2022). This article examines the intricate relationship between leaders, capital, and knowledge within a business environment. It uncovers how agile leaders foster a specific atmosphere of creativity and responsiveness while enabling organizations to seize opportunities and confidently tackle challenges. Lastly, it highlights the tangible benefits of an agile leadership approach.

This research aimed to assess IT's role in the creative economy. Three goals were: to gauge creative economy impact on tourist satisfaction, identify its influence on satisfaction, and provide smart tourism advice. Using a quantitative approach, data was gathered from 100 Smart Tourism users. Hypotheses were tested via Partial Least Squares Regression using SmartPLS. The model proved valid and reliable. Findings showed positive creative economy impact on tourist satisfaction. Despite its insights, the research is limited by a small sample size, potentially causing generalizability and bias issues. Practical implications include advocating smart tech adoption for improved satisfaction, promoting sustainable tourism collaboration, involving communities for aligned development, and considering environmental impacts in initiatives.
