Development cooperation, non-timber forest products and community empowerment: power and interests in a public-private partnership in the Brazilian Amazon
Authors: Tavares A.A.O. , Burns S.L.
Published: September 2023

In the Br azilian Amazon, around two million people depend on Non-Timber Forest Products (NTFPs) as their main source of cash income. Given the inherent bottlenecks to the commercialization of such products in the region, such as communities lacking access to credit and business skills,
alternative governance models have arisen with the aim of addressing such challenges. This stud y focused on one partnership between a donor, the German Cooperation Agency, and two private companies, a new trend in global governance under criticism for being donor dominated and disregarding
local interests. While this could undermine the legitimacy of such partnerships and compromise the replicability of the model, the achievement of economic empowerment of NTFP-reliant communities would alternatively deem this type of venture desirable and socially acceptable. Therefore, the
main goal of this study was to assess whether such configurations are able to economically empower communities in the state of Pará, Brazil. The results showed that this governance model is unable to generate high empowerment, due to conflicts with the interests of the most powerful
actor and external factors, which entails a need for an alternative model to achieve this goal in the region.
Relational Voluntary Environmental Agreements with Unverifiable Emissions
Authors: Cesi Berardino , D’Amato Alessio
Published: September 2023

Environmental regulation and pollution control may clash against the presence of unverifiable tasks, like source-specific emissions. To tackle this issue, we reshape a voluntary agreement instrument, already available in the existing literature, from a dynamic perspective by means of a relational contracting approach. We define a Relational Voluntary Environmental Agreement (RVEA) in an N firms symmetric context, and show that even if emissions are not contractible across firms, and therefore enforcement cannot be delegated to a third party, if firms are sufficiently patient, a self-enforcing RVEA induces the achievement of the environmental objective. Finally, our welfare analysis reveals a notable result: our RVEA can imply less free riding and be welfare-improving with respect to a Voluntary Environmental Agreement enforced by a third party (along the lines of McEvoy, D. M., and J. K. Stranlund. 2010. “Costly Enforcement of Voluntary Environmental Agreements.” Environmental and Resource Economics 47: 45–63).

Authors: Tomaiuolo Rossella , Banfi Giuseppe
Published: September 2023

The clinical laboratory is often evaluated for the volume of testing. However, it is undeniable that laboratory tests affect clinical decision-making and are included in many clinical guidelines, meaning their contribution to determining clinical outcomes. Therefore, the clinical laboratory professional has the task of enhancing laboratory tests by optimizing the request and reporting phase and addressing patient outcomes. This opinion paper, presenting practical examples of managing value-based health care in the clinical laboratory context, underlines the need to shift towards value-based management to optimize outcome-based health care.

Published: September 2023

Objectives

Chronic kidney disease (CKD) is a global health issue, ranking as the third leading cause of death worldwide. CKD diagnosis and management depend on clinical laboratory tests, necessitating consistency for precise patient care. Global harmonization of CKD testing through clinical practice guidelines (CPGs) is recommended. Prior to CPG development, assessing the current CKD testing landscape is crucial. In 2022, the European Federation of Laboratory Medicine (EFLM) conducted an online survey among European laboratories associated with EFLM, evaluating CKD testing practices, including new glomerular filtration rate (GFR) estimation methods. This report summarizes the 2022 survey findings and offers recommendations for improving CKD test standardization.

Methods

An online survey was conducted in November 2022 using a questionnaire hosted on LimeSurvey sent to European laboratories affiliated with the EFLM. The survey results were recorded in Excel files and analysed.

Results

The results highlight significant discrepancies among countries in unit expression, methods, cystatin C use, and GFR calculation equations. Additionally, limited attention to pediatric renal biology specifics, varied proteinuria and albuminuria result expressions, and limited awareness of GFR measurement methods through iohexol clearance are noted.

Conclusions

In an effort to enhance the standardization of crucial biomarkers utilized in nephrology for evaluating renal function and diagnosing kidney injuries, the EFLM Task Group on CKD suggests nine practical recommendations tailored for European laboratories. The group is confident that implementing these measures will minimize result expression discrepancies, ultimately leading to enhanced patient care.

Published: September 2023

Ceramics have enormous potential in several emerging technologies, including nuclear reactors. Materials with chemical inertness, high-temperature operation, and physical properties stability under applied radiation with high energy are all desired in this field of technology. Given these broad specifications, bismuth titanate ceramics may prove to be a valuable material. Regarding this task, the effect of gamma rays on the structural, optical, and ferroelectric properties of samarium-modified bismuth titanate ceramics was investigated. The Bi3.15Sm0.85Ti3O12(BSmT) compound was irradiated for 0, 50, 100, and 200 kGy using a60Co gamma source at a dose rate of 10 kGy h−1. The phase structure confirmed the orthorhombic, single-phase nature even after gamma irradiation. The results show that the unit cell volume decreases from 966.39 to 962.38 Å3with an increase in gamma dose from 0 to 200 kGy. The X-ray photoelectron spectroscopy study shows an irradiation-induced defect in the host matrix. The results show that the bandgap energy, dielectric constant, Curie temperatures, and remnant polarization slightly decreased with an increase in gamma irradiation. According to the findings of this study, the BSmT exhibits adequate stability against gamma irradiation, which offers tremendous promise in their utilization in nuclear reactor technology.

State-of-the-art deep learning models can converse and interact with humans by understanding their emotions, but the exponential increase in model parameters has triggered an unprecedented demand for fast and low-power computing. Here, we propose a microcomb-enabled integrated optical neural network (MIONN) to perform the intelligent task of human emotion recognition at the speed of light and with low power consumption. Large-scale tensor data can be independently encoded in dozens of frequency channels generated by the on-chip microcomb and computed in parallel when flowing through the microring weight bank. To validate the proposed MIONN, we fabricated proof-of-concept chips and a prototype photonic-electronic artificial intelligence (AI) computing engine with a potential throughput up to 51.2 TOPS (tera-operations per second). We developed automatic feedback control procedures to ensure the stability and 8 bits weighting precision of the MIONN. The MIONN has successfully recognized six basic human emotions, and achieved 78.5 % accuracy on the blind test set. The proposed MIONN provides a high-speed and energy-efficient neuromorphic computing hardware for deep learning models with emotional interaction capabilities.
“Standby Youth”?
Authors: Savić-Bojanić Maja
Published: September 2023

Approaches explaining the dynamics of informal youth participation during crisis typically examine youngsters’ political activity in light of the general understanding of political participation. In this article, I argue that such an approach falls short of understanding the motivations behind youth engagement during a crisis. Therefore, this qualitative study aims to investigate the motivations that triggered youth engagement in COVID-19–related protests and how they developed in response to government actions. It does so through 20 semi-structured interviews conducted across Bosnia and Herzegovina in the first six months of 2021 with 20 youth who had either no previous political participation experience or only voting engagement. The primary focus is on examining the motivations for two informal political activities—expression of opinion and protest. The findings reveal that the action-reaction patterns were not independent occurrences but evolved through three different stages each of which depended on distinctive motivations.

Authors:   National Higher School of Veterinary (NHSV), 16000, Algiers, Algeria, Barka Imane
Published: September 2023

To investigate the prevalence, bacterial spectrum of mastitis, and antimicrobial resistance of the causative staphylococci in Algerian dromedary camels, a total of 200 lactating camels were first examined for clinical mastitis and the healthy quarters were examined for subclinical mastitis using the California Mastitis Test (CMT). Milk samples from the affected quarters were collected aseptically and analysed using conventional bacteriological isolation and identification procedures. Staphylococcal isolates were then analysed for antimicrobial resistance. The overall prevalence of mastitis in camels based on CMT and clinical examination was 35 % (70/200), of which 7.5 % (15/200) was clinical mastitis and 27.5 % (55/200) was subclinical mastitis. At the quarterly level, the overall prevalence was 11.87 % (95/800), of which 2.62 % (21/800) was clinical mastitis and 9.25 % (74/800) was subclinical mastitis. A total of 98 bacterial isolates were identified from the 95 cultured milk samples. Staphylococci (70.4%) were the predominant isolates, with 31.63 % identified as coagulase-positive staphylococci (CPS) including S. aureus at 25.51 % and 38.77 % identified as coagulase-negative staphylococci (CNS). The remaining isolates were Micrococcus sp., Streptococcus sp., Bacillus sp., E. coli, and Enterococcus. Antibiotic susceptibility testing revealed that 24 (34.78 %) of the isolates were susceptible to all antimicrobial drugs tested, while 21.73 % (15/69) were multidrug resistant strains. The highest resistance rates were found for penicillin, tetracycline and erythromycin with 33.33 %, 31.48 % and 21.74 %, respectively. Therefore, the implementation of integrated approaches in the study is of great importance for the prevention and control of mastitis to improve the quality of camel milk, minimize economic losses and avoid significant public health risks.

Introduction and aim. The cumulative incidence of drug-induced thrombocytopenia (DIT) is 10 cases per one million people per year with a prevalence of approximately 25% in critically ill patients. This review provides a comprehensive view of drug-induced thrombocytopenia, diagnosis, underlying mechanisms, common strategies in therapeutics, and potential alternatives. Material and methods. Databases such as “Google Scholar”, “PubMed”, “Medline” and “MDPI” was used for literature review with the keywords, “platelets”, “platelet disorders”, “thrombocytopenia”, “drug-induced”, “oxidative stress” “plant extracts”, “phytochemicals”, “antioxidants”, for the articles published between 2013-2023 and written in the English language. Analysis of the literature. Several antimicrobials, anti-cancer drugs, and antivirals are often reported to cause adverse effects during treatment, such as thrombocytopenia. A thorough understanding of the underlying pathophysiology is important for appropriate treatment. Even though an improvement in platelet count is observed after the discontinuation of the causative drug, there is a dire need for treatment in some cases due to associated complications. There are various pitfalls with conventional treatments which include clinical complications and lack of effectiveness. Conclusion. Interventions in therapeutics through antioxidants can aid in faster recovery. Various plant extracts and phytochemicals have been employed as therapeutics in platelet disorders due to their exceptional antioxidant activity. It is imperative to explore the bioactive components of natural products and their influence on platelet efficacy. Also, it highlights how antioxidants can be used as a safe, yet effective option as therapeutics for treating a complicated disorder such as DIT or be used as supplements to prevent adverse effects of existing treatments involving antibiotics and chemotherapeutics.

Introduction and aim. This case report focuses on a 26-year-old female with metastatic melanoma. It highlights the diagnostic process, initial immunotherapy, disease progression, and successful response to second-line therapy. Emphasizing the importance of early detection, personalized treatment, and adaptive strategies, it provides valuable insights into managing this aggressive form of skin cancer. Description of the case. A 26-year-old Caucasian female presented with a suspicious pigmented lesion on her thigh in 2013. The lesion was confirmed as superficial skin melanoma. No lymph node biopsy was performed. In 2021, she had abdominal pain and imaging revealed melanoma metastasis in the peritoneum, lungs and brain. Genetic testing showed BRAF V600E mutation and PD-L1 expression in tumor cells. She received immunotherapy and radiation for a central nervous system metastases but developed a brain hematoma. Follow-up imaging showed disease progression. She started second-line therapy with iBRAF/iMEK, and her condition rapidly improved with regression of metastatic lesions. Follow-up imaging confirmed significant positive changes and almost complete regression of neoplastic lesions. She continues to receive the targeted therapy and shows a positive response. Conclusion. Early diagnosis improves outcomes in metastatic melanoma. Peritoneal metastases should be considered in patients with abdominal symptoms. The combination of gamma knife radiosurgery with immunotherapy or targeted therapy shows promise for managing brain metastases, but careful patient selection and monitoring are vital due to potential risks. Treatment responses in advanced melanoma vary, with this case highlighting a favorable response to BRAF/MEK inhibitor therapy in a patient with a BRAF gene mutation. Further research and clinical trials are needed to refine treatment approaches and improve outcomes in metastatic melanoma.

Published: September 2023

The aim: This study aims to determine the diagnostic value of lung ultrasound compared with radiography for respiratory distress in cats.

Materials and methods: The database of the veterinary center was analyzed. 130 animals diagnosed with pulmonary edema were selected. The lungs of sick cats were examined ultrasonographically; The line was counted in 4 anatomical sections on each hemithorax. A site was evaluated as positive when > 3 "B-lines" were detected. Animal treatment protocols were studied to clarify the final diagnosis (reference standard), and the sensitivity and specificity of lung ultrasound and chest X-ray for the diagnosis of pulmonary edema were calculated.

Result: Cats with a final diagnosis of cardiogenic pulmonary edema had a greater number of positive areas on ultrasound than those, in which respiratory distress was caused by non-cardiogenic pulmonary edema. The overall sensitivity and specificity of US for the diagnosis of pulmonary edema were 87 % and 89 %, respectively, and these values were similar to those of chest radiography (85 % and 86 %, respectively). The use of ultrasound led to a false diagnosis of cardiogenic pulmonary edema (ie, a false-positive result) in animals with diffuse interstitial or alveolar changes.

Conclusions: Ultrasound examination of the lungs in cats with respiratory distress syndrome is a promising diagnostic method. Emergency diagnosis of pulmonary edema in cats is difficult, especially in patients with severe shortness of breath, and limits the diagnostic evaluation. Chest x-rays are considered the standard diagnostic test, but the results are sometimes ambiguous and the process of obtaining the x-rays can increase respiratory distress in the animal.

According to the results of the study, it was established, that ultrasound examination of the lungs can be used to differentiate the causes of shortness of breath (cardiogenic and non-cardiogenic) with sufficiently high sensitivity and specificity and less influence of the iatrogenic factor on the development of respiratory distress in cats, compared to chest radiography

Published: September 2023

The object of research is the process of measuring the strength of the atmospheric electrostatic field. This paper is devoted to an analytical review and comparative analysis of modern methods and instruments for measuring atmospheric electrostatic field strength. The results of scientific research and modern practical technologies, which are used to develop technical means and increase the accuracy of measuring the strength of electrostatic fields, are considered.
In the work, the general functional requirements for the hardware of systems for measuring the atmospheric electrostatic field strength are formed and the main directions of research and practical tasks for its creation are defined. The design features and characteristics of existing measuring instruments are considered in detail. The advantages and disadvantages of electrometers, electrostatic field mills, microelectromechanical electrostatic field mills, and electric field imaging systems are determined given their portability, sensitivity, measuring frequency, accuracy, measurement range, linearity, and cost. The analysis of the state of modern methods and measuring instruments for the strength of the electrostatic field showed that one of the best solutions for measuring the electrostatic field strength of the atmosphere today is the use of an improved electrostatic field mill.
It was determined that one of the important problems for ensuring the development of methods and means of atmospheric electrostatic field strength measuring is the need to generalize the structure of the measuring instruments and calculate its metrological characteristics. It has been established that solving the problem of increasing the accuracy of atmospheric electrostatic field strength measurement requires a comprehensive approach based on improving the design of the sensor structure of the meter, increasing the accuracy of navigation and positioning, increasing the autonomy of work, improving communication and data transmission systems, as well as ensuring high stability and reliability of work under the influence of external factors. Improving the structure and improving the characteristics of electrostatic field mills in the future will ensure the necessary accuracy, compactness, and availability for measurement and its inclusion in the automated system of atmospheric electrostatic field monitoring and forecasting.
Analysis of methods of managing the environmental safety of the navigation passage of ships of maritime transport

Published: September 2023

The requirements of the MARPOL international convention on ensuring the environmental performance of marine diesel engines in relation to the emission of sulfur oxides, as well as marine fuels during navigation passages of sea transport vessels in special ecological areas, are given. The use of scrubber cleaning of exhaust gases and the use of fuel mixtures, which include biodiesel fuel, are considered as methods that meet these requirements. The research was carried out on ships of the Bulker Carrier class with deadweight of 63,246 tons during the navigation transition between the ports of Northern Europe. One of the vessels used scrubber cleaning of exhaust gases as a method of environmental safety management. The other is the use of fuel mixtures, which include biodiesel fuel. Both vessels are equipped with a 5S60ME-C8.2 MAN-Diesel&Turbo marine diesel engine as the main engine, and three 6EY18ALW Yanmar diesel engines as auxiliary engines. The ratio of sulfur oxides to carbon oxides – SO2/CO2 – was chosen as an indicator for evaluating the effectiveness of environmental safety management methods. This value was monitored and regulated by an automatic monitoring system. It was found that both methods meet the requirements of the MARPOL convention, namely, they will support the SO2/CO2 ratio in the range of 2.29–4.17 (when in special environmental control zones) and in the range of 6.46–20.83 (when in outside the zone of special environmental control). The use of environmental safety management methods increases energy costs for ensuring this process. When using exhaust gas scrubbing, additional power losses reach 237–278 kW. In the case of using a fuel mixture that includes biodiesel fuel, power losses amount to 18–20 kW. It has been experimentally confirmed that the use of a fuel mixture that includes biodiesel fuel is characterized by a lower level of environmental sustainability. At the same time, compared to the use of scrubber cleaning of exhaust gases, this method requires less energy consumption and is also characterized by simpler additional equipment. In this regard (and also taking into account that all the requirements of Annex VI MARPOL are provided), it is recommended as the main one to ensure the environmental safety of navigation passages of sea transport vessels.

Authors: Pavlenko Yevhen
Published: September 2023

The object of the current paper is the protection of information in the conditions of its interception by technical means of intelligence. According to this goal, considered the existing mathematical model of signal interception using radio-technical intelligence. In course of investigation, for getting final results based existing mathematical model analyzed the optimal scheme of signal detection with the help of intelligence receiver. As a result of this activity occurs four potential cases of signal detection which compared with established threshold H and accompanied by one of two error types: incorrect decision about the signal absence or incorrect indication of its presence. On the basis of the given cases suggested one of the possible variant for protecting of signal that goes beyond the controlled zone.
Using such dependencies as: an expression of the power flux density of radio electronic device antenna on its distance to the receiver in the direction of maximum radiation, the formula of signal power at the input of the receiving antenna, the ratio of the antennas coefficient of amplification and its effective scattering area was obtained: the dependence for calculating the power of output signal sufficient for reception within the controlled zone, but insufficient for its interception by technical means beyond its borders. Also, obtained graphical dependencies of minimal coefficient of amplification of transmitter antenna from maximal coefficient of amplification of transmitter antenna, from wavelength of radiation and from distance between transmitter and receiver.
Based on research results formed the conclusion regarding proposed method of information protection based on the mathematical model of the information leakage channel applying for radio intelligence.

Such an element of the system is ICU, the working body of which is the dosing piston. The main parameters of its operation when delivering fuel are the magnitude and speed of the stroke. For the load characteristics in the accepted range of the valve control valve opening angle jv from 6.6 to 14.4 °CA (2.18 times), the piston stroke was hp=4.29–8.61 mm (2.0 more). In this case, the dependence of hp on jv is linear.
Area of use of the data received during research, ship crews and the shore services providing operation of vessels are. A material is applied in process of high school and is already used in various educational forms. The given researches are useful to developers and builders of marine diesel engines of a considered class.

Published: September 2023

The object of research is the development of human capital of machine-building enterprises in the direction of increasing the level of their digital competencies. The links between the indicators of financial and economic activity of the enterprise and the rate of economic growth are studied, since digital technologies allow increasing labour efficiency and creating new added value. It has been found that the economic growth rate of an enterprise that implements digital technologies is higher than the growth rate of an enterprise that does not implement digital technologies. The article proposes a model of economic growth at the enterprise level, based on the concept of human capital, as well as measures that can be implemented by machine-building enterprises to improve their digital competencies. It is established that the cost of human capital at the selected enterprises is characterized by a significant level of underestimation, and it is found that the change in the cost of human capital correlates with the factors selected for analysis, which are to some extent related to the digitalization of processes at the enterprise. Several recommendations have been developed to improve the value and efficiency of human capital, create new added value and ensure economic growth. Those recommendations can be aimed at strengthening fixed assets, increasing demand through assortment changes towards automation and digitalization of processes, production, product, digital reorganization, as well as attracting IT professionals and specialists. Digitalization of products and processes can help to increase labor productivity, increase the number of potential customers and, possibly, investors, thereby strengthening capital equipment. The article notes that digitalization today means competitiveness in the domestic and foreign markets, strengthening of the company's position in the economic environment and transition to a balanced enterprise development strategy where the value of human capital will be higher, and as a result, labor productivity will increase.

Published: September 2023

To identify the propagation mechanisms and the adaptive strategies of oat seedlings exposed to NaCl, NaHCO3 and Na2CO3 the main salts in the soils of the salt-alkali grasslands of the Songnen Plain of China, growth rates and physiological indices of oat seedlings were measured in plants grown in soils with different concentrations (48-144 mmol L-1) of the three salts. The results demonstrated that although oat seedlings survival rates were unaffected by NaCl stress, the tiller number, plant height, and shoot and root dry weights decreased with increasing salt concentration, in the order of Na2CO3＞NaHCO3＞NaCl. In addition, propagation mechanisms higher concentrations of Na+ accumulated in the shoots and roots of oat seedlings under Na2CO3 stress and NaHCO3 stress than in seedlings under NaCl stress. Reductions in concentrations of K+ were also greater under both Na2CO3 and NaHCO3 stress than NaCl, especially in the roots. Large amounts of Cl－ and proline were found to accumulate in oat seedlings, most likely as a strategy for maintaining osmotic and ionic homeostasis under NaCl stress.

Authors: KURNAZ Aysel
Published: September 2023

Voluntary simplicity is a lifestyle in which individuals consciously prefer to consume less and adopt a simple life. On the other hand, conspicuous consumption refers to the pretentious purchase of luxury and expensive products in order to gain social status or attract attention. In this study, an answer is sought to the question of how lifestyle choices and consumption habits affect the happiness levels of individuals. In this context, the voluntary simple lifestyle and the conspicuous consumption orientation, which express two different approaches that can be effective on happiness, are examined. The basic objective of this research is to investigate the effects of individuals’ voluntary simple lifestyle and conspicuous consumption orientation on their happiness. The ancillary objective of the research is is to designate the differences in the effect of voluntary simple lifestyle and conspicuous consumption orientation on happiness by gender, educational status and age. In line with these objectives, 764 participants were accessed through an online questionnaire by way of using convenience sampling technique. When the basic findings were evaluated, the individuals’ voluntary simple lifestyle averages were found to be at a high level. This was followed by the averages of the happiness variable. The averages of the conspicuous consumption orientation were at the lowest level compared to the other structures. While there were significant differences in individuals’ happiness and voluntary simple lifestyles according to demographic characteristics, no differences were found in conspicuous consumption orientation. Hypothesis test results are demonstrate that voluntary simple lifestyle has a positive and significant effect on happiness. Yet, a significant effect of conspicuous consumption orientation on happiness could not be designated. Moreover, it has been designated that the effect of voluntary simple lifestyle on happiness differentiates based on gender, educational status and age. The effect of conspicuous consumption orientation on happiness differentiates only based on educational status.

The relationship between culture and firm sustainability practices is widely recognized in the literature, but little is known about a sustainable culture, particularly in a context of corporate social responsibility, since sustainability in manufacturing firms involves managing physical aspects of production and transforming the organization’s culture into a sustainable culture. However, the existing research in the literature has been mainly oriented towards the analysis of a culture that focuses on improving firm financial performance. The present study aims to fill this existing gap, and generate new knowledge of the relationship between these three constructs, distribute a questionnaire to a sample of 300 manufacturing firms in Mexico, and analyze the data through partial least squares structural equation modelling. The results showed that the sustainable culture has positive effects on social responsibility and firms financial performance, and corporate social responsibility has positive effects on financial performance of manufacturing firms. Thus, the results obtained allow us to conclude that manufacturing firms that have adopted a sustainable culture have not only improved their social responsibility, but also their financial performance. However, when corporate social responsibility acts as a mediating variable, it further improves firm financial performance.

In the realities of today's world, including the transition from WEB 2.0 to WEB 3.0. Every day there are new products that make human life more convenient. This applies to software that is used in business or everyday life. The emergence of new software from different levels of experts bear in themselves both positive and negative aspects. Following the emergence of new technologies, new threats also appear. Over 2022, 70 % of the most exploited vulnerabilities were due to software vulnerabilities. This article attempts to develop an effective software vulnerability analyzer with monitoring functionality capable of detecting new vulnerabilities without causing a load on the network. The article will describe the stages of the article's development, the principle of the program's work, information about the sources of obtaining data on the target system and on the vulnerability database. The monitoring process and operator's capabilities in obtaining information about the vulnerabilities will be described. To test the efficiency of the work, a test bench with vulnerabilities will be prepared on which the efficiency of the developed analyzer and the tool with similar functionality will be tested.
