Ser Capitão-do-mato
Authors: Machado Montedo de Oliveira Luísa
Published: December 2024

Esta apresentação visa exibir dados sobre a nomeação de capitães-do-mato pela Câmara Municipal de Porto Alegre, entre os anos de 1768 a 1828; bem como, fizemos uma busca nominativa nos inventários post mortem dos sujeitos que atuaram como capitães-do-mato, a fim de apurar se esses indivíduos acumularam algum pecúlio no decorrer de suas vidas. O objetivo desta pesquisa é debater se atuar como um agente de repressão contra escravizados era uma forma de ascender socialmente, ainda que de maneira limitada. Os referidos capitães-do-mato eram nomeados pelas câmaras municipais e possuíam a função de recuperar escravizados prófugos e destruir quilombos. Inferimos que os capitães-do-mato eram, em sua maioria, homens de cor, muitas vezes pretos ou pardos forros, buscando alguma alternativa de sobrevivência em uma sociedade escravo.

Using prefabricated wood light-frame in multi-storey and non-residential construction projects: Motivations and barriers of professionals in Quebec
Authors: Giorgio Baptiste , Blanchet Pierre , Barlet Aline , Gaudelas Adrien
Published: December 2024

Despite prefabricated wood light-frame construction’s technical viability and ability to address labor shortages and industry productivity issues, its adoption remains limited. As an alternative to steel and concrete in non-residential buildings of four storeys or less and dwellings of five and six storeys, they represent only 23% and 6% of market shares, respectively. Based on a purposive sample of 40 interviews with diverse construction industry professionals in Quebec (Canada), the representations of prefabricated wood light-frame construction was highlighted. A thematic analysis identified the motivations and barriers to prefabrication adoption and the reasons for these positions more precisely. This work examined whether these perceptions differ significantly according to main professional activity. The findings confirm existing literature while providing deeper insights into motivations and barriers, revealing new viewpoints. Respondents primarily cited expertise as the most critical barriers. Availability of labor, cost, productivity, and construction quality were identified as key motivators, while manufacturing capacity and coordination were perceived with mixed opinions. Analyzing response profiles suggests that different stakeholders generally have similar perceptions. This research will aid in refining policies and strategies to encourage the widespread adoption of prefabricated wood light-frame in construction practices.

Published: December 2024

The 3D printing techniques have found applications across diverse fields, significantly enhancing design and manufacturing processes. The impact of this growth is particularly notable in radiology, where 3D printing has been applied to developing quality control tools and advancing dosimetry techniques. 3D printing has the advantage of having a wide variety of plastic materials which can be used in the manufacturing process; there is a scarcity of work developed to evaluate the attenuation of the x-ray beam of the materials used in printing 3D models for phantom development. This paper aims to show our results on the imaging characteristics investigation of 15 3D printable materials. 3D objects were printed as cubes of 20 x 20 x 20 mm3 with a 100% infill and 45°/45° rectilinear structural pattern, and images acquired in a DR X-ray unit were analyzed with ImageJ software. Imaging pixel values, Signal-to-Noise Ratio – SNR and Contrast-to-Noise Ratio – CNR were evaluated and compared between the 3D-printed cubes and a standard chest phantom. When comparing the SNR for plastic materials and chest structures, significant differences were found. Similar results were found for the CNR. The differences were noted for both plastic materials, Tungsten and Bismuth, that demonstrated statistically significant values of SNR compared to the lung (p < 0.0001) and right rib (p < 0.0001).  Tungsten and Bismuth filaments were found to have the potential to represent the SNR for intermediary and high-density structures. Scapula was the only anatomical structure with no statistically significant difference of the CNR for SILK (p ≥ 0.074), ABS (p ≥ 0.086), PVA (p ≥ 0.917) and ABSpremium (p ≥ 0.955). The study of potential radiological 3D printing materials for diagnostic radiology phantom development revealed important imaging characteristics for the plastic materials using the Fused Filament Fabrication technique.

The global decarbonization goals have caused a series of fundamental changes in the power systems in developed countries. New approaches and concepts for constructing modernized electrical grids are needed to increase energy systems' efficiency, reliability, and sustainability. Ukraine`s energy sector is in particular need of new approaches to the construction of power supply systems with the introduction of renewable sources and distributed sources. According to the Roadmap Concept for the Implementation of the "Smart Grid", the restoration of facilities damaged by Russian attacks will be carried out using "smart" technologies. Transactive energy is a new approach for efficient and reliable integration of distributed energy resources and meeting the demands of electricity consumers. Another variant of the new energy organization of the future is the Internet of Energy – a type of decentralized power supply system where intelligent distributed management is implemented. The article presents an overview and analysis of transactive energy and the Internet of Energy, the concept of building an energy system based on energy cells. Such systems are decentralized, can work without a network, and satisfy the needs of consumers due to the optimal use of energy from distributed energy resources (renewable sources, distributed sources, and storage systems). Transactive energy can be considered a free Internet-enabled electricity market, where all participants can safely trade at a reasonable price and with real-time calculations. The operation of a decentralized transactive system in steady-state and transient modes of operation has been demonstrated, as an example. The considered construction of the power system corresponds to the concept of "smart grids", showing a high potential for implementation in Ukraine, which will increase the share of RES, accelerate decarbonization, increase the stability and reliability of the power system of Ukraine, and lead to the development of local electricity markets.

PHOTOVOLTAIC GENERATION FORECASTING MODELS: CONCEPTUAL ENSEMBLE ARCHITECTURES
Authors:   General Energy Institute of NAS of Ukraine, 172, Antonovycha St., Kyiv, 03150, Ukraine, Matushkin Dmytro
Published: December 2024

The decisions regarding power regulation, energy resource planning, and integrating “green” energy into the electrical grid hinge on precise probabilistic forecasts. One of the potential strategies to enhance forecast accuracy is the utilization of ensemble forecasting methods. They represent an approach where multiple models collaborate to achieve superior results compared to what a single model could produce independently. These methods can be categorized into two main categories: competitive and collaborative ensembles. Competitive ensembles harness the diversity of parameters and data to create a rich pool of base models. This approach may encompass statistical analysis, noise filtering, and anomaly elimination. On the other hand, collaborative ensembles rely on the interaction among models to achieve better outcomes. These methods encompass strategies such as weighted predictions, voting, aggregation, and a combination of model results. The research of ensemble forecasting methods in the context of photovoltaic generation is highly relevant, as solar energy represents a crucial source of renewable energy. Accurate predictions of solar energy production address the challenges related to the efficient utilization of photovoltaic panels and their integration into the overall energy system. This paper investigates conceptual ensemble architectures for photovoltaic energy forecasting. These architectures encompass various methods of aggregating base models within an ensemble, allowing for the consideration of different aspects and peculiarities of solar data, such as solar irradiation intensity, meteorological conditions, geographic factors, and more. These conceptual models are developed based on well-established statistical, machine learning, and artificial intelligence methods. Therefore, this paper provides an overview of ensemble forecasting methods for renewable energy, covering competitive and collaborative ensembles, as well as developing conceptual models for solar energy forecasting. This work aims to elevate the accuracy and efficiency of forecasts in the realm of renewable energy, representing a significant step in the advancement of sustainable and environmentally friendly energy production.

The article highlights three main factors that influence the forecast of the consumption of energy in the economy of Ukraine. These are structural shifts in its economy, changes in the structure of energy consumption in Ukraine, and volumes and directions of reduction of greenhouse gas emissions (GHG) in the conditions of compliance with international emission limitations. The conservative scenario of the development of the country's economy is considered. It predicts a moderate recovery, with the economy growing at 2.5 % per year. This pace has been chosen under the condition of the continuation of russia's armed aggression against Ukraine and the end of the active phase of hostilities by the end of 2025. The change in the structure of the economy during russia's military aggression against Ukraine was studied. The directions of further development of key sections of the economy have been determined. Strategic measures to reduce GHG emissions are highlighted, primarily in industry and in the energy sector in particular. Reducing fuel consumption by types of industrial sectors in Ukraine will be achieved through the introduction of energy-efficient technologies and processes aimed at reducing energy consumption in production, by switching to the use of more ecological energy sources, such as renewable energy sources; modernization of industrial facilities and equipment to reduce fuel consumption; implementation of energy saving and energy efficiency promotion programs in industry; reforming the energy sector and increasing energy efficiency in general. According to the updated nationally defined contribution of Ukraine to the Paris Agreement in 2021, the country committed to achieving a reduction of greenhouse gas emissions by 35 % from the 1990 level by 2030 and switching to energy-efficient and low-carbon technologies.

An urgent practical task is to ensure the serviceability and safety of complex technical and information systems by monitoring their current states. Additionally, an important task is to use control charts to automatically detect the moment when certain limit states are exceeded by the characteristic features (parameters) of the technological process. In practice, it is quite common for characteristic features to be correlated. The presence of correlation affects the effectiveness of control charts in determining the moment of process disruption. The study objective is to compare the effectiveness of using different control chart types to control a correlated parameter process. The following control charts were studied: Shewhart, Hotelling, and modified Shewhart charts − principal component charts. Numerical modeling of a two-parameter process was conducted with the introduction of a non-random change in one of them at two control points, i.e., the process disorder was modeled at the appropriate time points. Subsequently, statistical studies of the modeled process were conducted using three types of control charts. The results revealed that the Shewhart charts did not reveal any process disruption, which is explained by the correlation of the parameters. Hotelling charts revealed a processing disorder at two points, but they do not indicate the cause of the disorder. The calculated partial Hotelling criterion did not indicate the cause of the disorder. The principal component charts revealed both the presence of a process disorder in two points and identified which parameter caused the disorder. This result demonstrates the effectiveness of principal component charts in detecting process disorder with correlated parameters, as well as their superiority over other charts that were studied. In addition, with an increase in the number of parameters, this method becomes even more effective, as it allows to reduce the number of parameters studied while maintaining their statistical significance.
Keywords: effectiveness of control charts, Shewhart charts, Hotelling charts, principal components, statistical quality control, correlation of parameters.

Monitoring and assessing the security of electricity supply in Ukraine are becoming increasingly important due to the integration of the integrated power system with the European power system and the need to ensure uninterrupted operation in parallel. This paper aims to test the use of an indicative approach to assessing the security of electricity supply. The paper considers the possibility of using an indicative approach to assessing the security of electricity supply. Within this paper, the indicative approach is understood as a method of management and planning based on the use of indicators or indicators to assess the state and efficiency of a particular process, system, or phenomenon. The main focus is on forming a list of indicators to assess the security of electricity supply. The initial assessment of the level of the indicator for ensuring the balanced reliability of the power system and the quality and level of maintenance of power grids will allow us to assess the security of supply in general. Unlike the existing principles for assessing supply security, this approach allows for systematic monitoring and objective data on which to base strategies and plans, which increases management efficiency. To solve the problem of finding an assessment of the security of the electricity supply, an indicative approach may be proposed for use, which provides a unified indicator that allows further analysis and formation of a list of tasks for the development of the Ukrainian power system. The feasibility of applying the indicative approach is proved by the example of calculating all weighted average integrated indicators and the level of security of electricity supply. The above calculations and conclusions can be extended to the indicators of the Reports of the Ministry of Energy of Ukraine for other years.
Keywords: indicative approach, security of electricity supply, indicator, indicator, assessment, risk, statistical data, standardization, unified indicator.

The article is devoted to the analysis of the evolution of the concept of security in the context of modern global warming. The features of three stages of this evolution from energy security to environmental one and further to climate security are considered. It is noted that these stages of evolution correspond to a certain "source base", namely, energy security - to the resources of "primary" bioenergy, environmental security - to fossil fuels, fissile materials and limited renewable energy sources (RES), and climate security - predominantly RES. The presence of a close connection between changes in the "source base" and technological structures - pre-industrial, industrial and modern information - is indicated. Data from the analysis of priorities and practices of energy, environmental and climate security are provided. The features of energy security are considered and ecological imbalance in the biosphere at this stage is indicated, caused by the depletion of energy resources and the growth of anthropogenic load on the environment, which began to exceed its adaptive capabilities. Environmental security is analyzed in the context of modern global warming. The emergence at this stage of the idea of ​​energy transition associated with the replacement of fossil energy resources with renewable energy sources is noted. The features of climate security, the content of which has replaced the agenda of environmental security, are considered. It is noted that the problems of climate security should primarily include issues of adaptation and mitigation of the climate, and secondly - geoengineering climate management. Certain attention is also paid to such an important feature of climate security as its anthropocentrism, which is associated with the anthropogenic nature of modern global warming and the need to solve climate management problems primarily from the standpoint of usefulness for human systems.
Keywords: global warming, evolution of the concept of security, ecology, climate, energy supply.

Der vorliegende Beitrag widmet sich den Cuentos de la oficina des argentinischen Schriftstellers Roberto Mariani aus dem Jahr 1925. Ausgehend von Überlegungen Max Webers zur bürokratischen Effizienz und Michel Foucaults zur Disziplin, werden daraus ausgewählte Texte – Balada de la oficina, Rillo und Santana – auf die dort wirkenden Disziplinierungsmechanismen sowie deren literarische Darstellung untersucht. Die Erzählungen, die sich um die Figuren Rillo und Santana entfalten, greifen die in der Balada de la oficina episch vorausgedeuteten Versprechungen, Forderungen und Drohungen durch das personifizierte Büro auf und zeichnen ein prekäres Bild des bonaerensischen Büroangestellten im modernen Kapitalismus der 1920er Jahre. Mit Foucault und Weber soll der Frage nachgegangen werden, inwieweit die obigen im Hinblick auf die europäische Moderne entworfenen Konzepte zum Verständnis von Disziplinierungsmechanismen im Rahmen der Etablierung kapitalistischer Strukturen am Cono Sur beitragen können. Besonders geeignet erscheint hier die Wahl des Autors Roberto Mariani, der mit den Cuentos de la oficina erstens den Gründungstext für die argentinische Büroliteratur geschaffen hat und zweitens um 1920 selbst als Büroangestellter tätig war.

African swine fever (ASF), caused by the African swine fever virus (ASFV), poses a significant threat to pig populations worldwide. ASFV is a double-stranded DNA virus. In recent years, 54 structural proteins and more than 100 proteins have been involved in viral infection found in macrophages of diseased pigs. Among these, p49 and p72 are essential capsid proteins crucial for forming the viral capsid. Additionally, pE199L and pE248R, located in the inner viral membrane, are critical for membrane fusion, a necessary step for viral entry into host cells. Another important player is CD2v, a type I transmembrane protein involved in the infection process. In this research, to develop subunit vaccines against ASFV, we focused on cloning the genes encoding these five proteins—p49, p72, pE199L, pE248R, and CD2v—into the pPIC9K plasmid for expression in the Pichia pastoris GS115 yeast strain. The viral genomic DNA was extracted from blood samples of infected pigs, and the genes encoding the five proteins were successfully amplified using Phusion PCR. The PCR products of each gene were then digested with EcoRI and NotI restriction enzymes and ligated into the pPIC9K plasmid. After that, we transformed the recombinant plasmids into Escherichia coli DH5α for amplification and purification. The plasmids were subsequently linearized with SalI and introduced into P. pastoris GS115 through electroporation. The selection of appropriate media and PCR analysis of the genomic DNA confirmed the successful generation of five recombinant P. pastoris GS115 strains. This work paves the way for the development of a recombinant protein vaccine against ASF by using the Pichia pastoris GS115 in the future.

Vietnam has a rich and profound traditional medicine system that is widely used today. Medicinal plants are used to treat colds, coughs, bone and joint diseases, digestion, respiratory diseases, etc. In this study, leaves of Artemisia vulgaris, Taraxacum officinale, Blumea balsamifera, and flowers of Xerochrysum bracteatum from the Asteraceae family were selected to determine the antioxidant capacity and relationship with the active ingredients in the plants. The methanolic extracts were screened for chemical compositions via the total phenolic content (TPC) assay, the total flavonoid content (TFC) assay, and DPPH radical scavenging activity. The highest radical scavenging activity was observed in the flowers of X. bracteatum (IC50 = 0.061 mg/mL), followed by the leaves of Taraxacum (IC50 = 0.313 mg/mL), A. vulgaris (IC50 = 1.367 mg/mL), and B. balsamifera (IC50 = 1.4502 mg/mL). The TPC of the studied plants ranged from 19.98 ± 1.355 to 195.78 ± 42.518 mgGAE/g extract, while the TFC ranged from 60.31 ± 1.725 to 339.14 ± 26.299 mgQE/g extract. The highest TPC and TFC were recorded in the methanol extract of X. bracteatum. The strongly negative correlation between the TPC and TFC and the IC50 values ​​(R2 = -0.78, R2 = -0.76) suggests that TFC and TPC could strongly contribute to the antioxidant activity of these plants. These results not only highlight the relevance of these plants in traditional medicine but also scientifically validate their use, particularly in the context of their antioxidant properties. The study underscores the close relationship between the traditional use of these plants and their scientifically observed effects, reinforcing the value of folk remedies.

Low biodegradability of several dyes leads to their accumulation in water, causing ecological and health damage. The adsorption and, in particular, biosorption processes are widely applied for the wastewater treatment. This article presents the first comparative study of the Allura red dye removal under neutral pH at 25 oC applying novel biosorbents: carboxyethyl chitosan hydrogel (CEC) and cryogel of carboxyethyl chitosan cross-linked with butanediol-1,4 diglycidyl ether (DEB-CEC). The gels were synthesized in “green” manner, and the characterization revealed porous structure and high swelling for both biopolymer compositions, which are the properties  important for adsorption. The kinetic studies demonstrated that the adsorption rate for DEB-CEC is better represented by pseudo-second-order, while CEC followed better pseudo-first-order kinetics. The adsorption isotherm of Allura Red suited the Temkin model for both samples, with the maximum adsorption capacity of 22.523 mg/g (45.4 μmol/g) and 10.482 mg/g (21.1 μmol/g) for CEC and DEB-CEC, respectively. The results demonstrated that CEC and DEB-CEC polymers can be used as biodegradable and eco-friendly biosorbents for Allura Red dye removal from aqueous solutions, making these biosorbents promising for wastewater treatment and prevention of the azo-dye environmental pollution.

Tetraarylantimony(V) carboxylates based on 5-carboxyl and 6-carboxyl 2,2’-bipyridines (4 compounds) were synthesized for the first time. The structure of one of the compounds was confirmed by X-ray diffraction analysis. It was shown that the carboxyl group participates in the coordination of the antimony(V) cation, but the bipyridine fragment does not. The antitumor activity of the new complexes was assessed by molecular docking, and the most probable targets were determined. It was shown that the affinity of ligands to them is higher than that of the corresponding complexes. The best results were obtained for complex 3a; its inhibition of VEGFR2 is 74% more effective compared to the native ligand. In addition, the primary photophysical properties of the new carboxylates in acetonitrile solutions were studied. It was shown that the luminescence quantum yield values strongly depend on the position of the carboxyl group: for 5-substituted compounds they reach 65.0%, while for 6-substituted ones they have an extremely low ( 0.1%) value. At the same time, the absorption and emission maxima are within 300–314 nm and 364–403 nm, respectively.
Italians and Global Warming Skepticism: opinions and Ways of information
Authors: Pellegrini Giuseppe , Loner Enzo
Published: December 2024

Scientists, policy-makers, entrepreneurs, and citizens are strongly concerned about the harmful consequences of climate change. Individual beliefs about social norms and economic and political orientations regarding trust and social relationships call into question values ​​such as care for the environment, autonomy, freedom of choice, and risk. Given the influence of the media on public perceptions, it is essential to consider how, with what means, and towards which issues citizens orient themselves to address this epochal phenomenon. Using quantitative and qualitative methods of analysis, the present study investigates the characteristics and reasons of the individuals who are skeptical of the evidence of global warming in Italy and how the Italians inform themselves about this issue.
Quantitative analysis was performed on two representative samples of 1011 and 1030 individuals from Observa Science in Society in 2022 and 2023 through a structural equation model (SEM) to study the dimensions associated with climate change skepticism. Qualitative research on a panel of 93 Italians selected by gender, cultural level, and area of residence further highlighted the information channels, methods of use, and the main dimensions of interest in climate change. This robust mixed-mode methodology, which ensures the credibility and reliability of the study's findings, is a key strength of this research.
Our results confirm that less trust in science and older age are associated with skepticism. Furthermore, traditional media are the primary means of information despite the growing importance of social relations - including social networks - in shaping opinions on the environment and climate change. The conclusions also reveal that experts influence the public, even if personal experience often mediates this effect. These findings have practical implications for understanding and addressing climate change skepticism in Italy, equipping researchers, policymakers, and individuals interested in this issue with the knowledge to make informed decisions and take effective action.

Traditional news media have long been the primary source of information on environmental issues, influencing public perceptions and shaping discourse on ecological sustainability. Media representations play a central role in forming public opinion, especially on climate change, which has become a highly politicized and polarized topic, both offline and online. Political ideologies, economic interests, and government agendas significantly shape how the public discusses and responds to strategies for addressing climate change.
This study focuses on the most engaging environmental content posted on social media and explores whether climate change is the dominant topic in these discussions. It also examines which actors (e.g., politicians, institutions, citizens) and sources (legacy media or alternative media) are featured in the most popular content. The aim is to identify the factors that drive user engagement on platforms like Facebook, Twitter (now X), and YouTube, and to investigate how social media users contribute to the plurality and diversity of voices shaping the discussions on environmental issues. The study considers whether these platforms support the democratic potential of public debate.
Over a three-month period (Sept.–Nov. 2021), the study monitored social media and compared non-professional user’s posts with professional content from legacy media. The findings show that institutional actors dominate the online debate on environmental issues and climate change. Facebook engagement largely revolves around content from organizations and politicians, while Twitter users refer to organizational sources. On YouTube, however, local and regional media content is more prominent. This is surprising since surveys suggest that Greeks mistrust legacy media and prefer social media for information, viewing traditional outlets as corrupt and biased towards the dominant class.

Genetic polymorphisms in genes that enable the production of an effective host immune response, such as single nucleotide polymorphisms (SNPS) in the IL-6, INF-alpha, IFN-gamma, IL-10, TGF-beta genes can cause unfavorable clinical conditions or susceptibility to pathologies. The objective of this work is to evaluate the epidemiological and genetic profile of professionals from health institutions during the first pandemic wave. A case-control study was performed with convenience sampling from health institutions (HI) workers from Belém-PA, Northern Brazil (N = 213), divided into symptomatology groups (Asymptomatic-AS, n = 91; and Symptomatic-SI, n = 122); and severity groups classified by chest computerized tomography-CCT data (symptomatic with pulmonary involvement-SCP, n = 37; symptomatic without pulmonary involvement-SSP, n = 8). Genotyping was performed by sanger sequencing for SNP TNF-α -308 G/A (rs1800629), IFN-γ +874 T/A (rs2430561), TGF-β codon 10 (rs1982073), codon 25 (rs1800471), IL-6 - 174 G/C (rs180079), IL-10 - 1082 A/T (rs1800896), -819 C/T (rs1800871), and -592 A/C (rs1800872), and statistical analysis through the Epilfo program. Significant association was observed between the presence of comorbidities and poor prognosis of COVID-19 (especially between COVID-19 and overweight and obesity). Only the TNF-α 308 G/A snp was significantly associated with the symptoms and severity of COVID-19. These findings about this TNF-α SNP passed in the multiple testing correction at a false discovery rate (FDR)< 0.05. These data can help medicine and the scientific community understand the influence of genetics and epidemiological parameters in combating COVID-19.

The present study was aimed at evaluating the nutritional characteristics of bio-enriched oyster mushrooms. Cereal, leguminous and oilseed waste was used as substrates. Rice, soybean and mustard straw performed the best among all substrate fortified by adding Se and Zn salts individually and in combination at three different doses (25, 50 and 75 mg/kg) for nutrient analysis. The results showed that highest carbohydrate, 54.01 percent and protein content, 29.41 percent after fortification with Se and Zn at 75 mg/kg as compared to other doses on different substrates. Se at 75 mg/kg gave maximum carbohydrate (60.29%) and protein content (32.32%) in soybean straw while Zn supplementation at 50 mg/kg resulted in high fat content (2.74%) while rice straw had maximum fiber content (18.12%). Based on maximum yield, best dose of both the salts (25 mg/ kg of substrate) were combined and evaluated. The results indicated that soybean straw had the highest nutrient contents having 55.00 percent carbohydrate and 27.72 percent protein content. It was concluded that fortification with selenium and zinc increased the nutritional composition of Pleurotus ostreatus in comparison to control.

Published: December 2024

Bu araştırmanın amacı, anne bekçiliği boyutları (teşvik, engel ve kontrol) ile ergen uyumu arasındaki ilişkide babanın algıladığı ve ergenin algıladığı baba katılımının aracı rolünü incelemektir. Çalışma kapsamında ergen uyumu değişkeni; sosyal beceri, öznel iyi oluş, duygu düzenleme ve evlatlık inancı değişkenleri ile oluşturulmuştur. Çalışmanın örneklemini 10-14 yaş aralığındaki 783 ergen (YaşOrt.= 11.99, S= 1.20) ile anne ve babaları oluşturmuştur. Gerçekleştirilen Yapısal Eşitlik Modeli (YEM) analizi sonuçlarına göre, kabul edilen model, anne bekçiliği boyutlarının ergen uyumunu doğrudan yordamadığını ortaya koymuştur. Bunun yanı sıra annenin teşvik edici ile kontrol edici bekçiliği, babanın algıladığı katılımdan ergenin algıladığı katılıma giden yol aracılığıyla ergen uyumunu yordarken, annenin engelleyici bekçiliği yalnızca ergenin algıladığı baba katılımı yolu üzerinden ergen uyumunu yordamıştır. Elde edilen sonuçlar genel olarak, artan baba katılımı ve sonuç olarak daha iyi ergen uyumunun, annenin teşvik edici bekçiliği ile olumlu, engelleyici ve kontrol edici bekçiliği ile olumsuz yönde ilişkili olduğuna işaret etmektedir. Ulaşılan sonuçlar alanyazın çerçevesinde tartışılmış olup, ergen uyumunu desteklemeye yönelik gerçekleştirilecek müdahale programlarına yol gösterici olabilir.
