Adolescent Agency in Collectivist Cultures: Development and Validation of Personal Agency in Adolescence Scale (PAAS) among Indian School Students

Adolescents exercise personal agency as they plan their life, set goals, make decisions, and perform various actions that define their life course. The objective of this study was to develop and validate a scale measuring the personal agency of adolescents in a collectivist culture, namely, India. Moreover, we integrated key concepts from the existing literature and considered the sociocultural experiences. The newly constructed scale’s psychometric properties were tested on two samples of adolescents aged between 14 and 17 from rural and urban areas. The Exploratory Factor Analysis (EFA) conducted on sample 1 (N = 571) demonstrated that the proposed six-factor model of the Personal Agency in Adolescence Scale (PAAS) was relevant to measure adolescent personal agency. Confirmatory Factor Analysis (CFA) performed on sample 2 (N = 499) showed that the six-factor model had good construct validity and that the 23-item scale could adequately measure the construct. The results also supported the internal consistency and reliability of the scale. Further, the scale’s concurrent validity with other agency scales was established. Bivariate analysis showed moderate and positive correlations with other related scales. PAAS was also moderately correlated with adolescents’ self-esteem and psychological well-being. The findings show that PAAS is a valid and reliable scale that can be employed to assess adolescents’ agency. This tool can be used by those in education, counselling, and research to measure the adolescents’ exercise of personal agency and its relations to other psychological constructs.

moisture supply, the country's well-being and food independence depend on the development of irrigated agriculture. The goal of irrigated agriculture in Burundi is not only to ensure high produc-tivity of agricultural plants, but also to promote the reproduction of soil fertility, the economical use of resources, and the environmental safety of agriculture. Achieving the set goals is possible by ob-serving a specific reclamation regime. This regime consists of a set of requirements for controlled factors that ensure harmonious coexistence and functioning of the landscape space and agro-cenoses in the Republic of Burundi. The purpose of this research is to determine whether climate analysis data can be used to support the reclamation regime of irrigated lands in the Republic of Burundi. This will be achieved by comparing the climate analysis data with data obtained from direct obser-vations at meteorological stations located within the Republic of Burundi, and assessing the reliabil-ity of the results

Формування траєкторії керованих літальних апаратів

Currently, there is an increased interest in the creation of flight control systems for unmanned aerial vehicles, which, taking into account real conditions, would ensure its trajectory and thereby determine the effectiveness of the use of the aerial vehicle. Aircraft navigation, in particular ballistic cruise missiles, requires the formation of high-precision control in order to achieve both final results and local optimization tasks at each of the flight stages: take-off, departure to set trajectories, maneuvering, etc. The development of admissible control and its optimization by computer-mathematical methods of modeling and optimization is a time-consuming process and requires significant expenditures of various types of resources. An element of the effectiveness of such a mathematical apparatus for guaranteeing and increasing the reliability and effectiveness in achieving the set goal is the speed of calculations, which, in turn, requires the simplification of the mathematical model by obtaining functional dependencies for calculating the flight trajectory, avoiding complex mathematical calculations. The complete working model for calculating the desired trajectory of the aircraft will be determined by the specified control functions and will be provided by a system of partial differential equations with time, and the necessary parameters for calculating all aerodynamic forces and moments are tabular data in most cases. A mathematical model for solving the task of forecasting navigation for such complex controlled systems is proposed to be carried out using two coordinate systems: starting and speed. Moreover, all calculations of the velocity vector, which depends on the net effect of three aerodynamic forces acting on the aircraft, should be carried out in the speed coordinate system, and coordinate control of the flight along the entire dynamic trajectory should be determined in the starting system

THROUGH THE LENSES OF ACTOR-NETWORK APPROACH - THE DIGITAL TRANSFORMATION OF NIGERIAN AGRICULTURAL RESEARCH OUTREACH CENTRE

Agriculture’s goal in Nigeria is to provide supportive resources to sustain mankind, environmental resilience against climate change, nation’s economy, irrespective of geographical location or social status with a total land of 911,000 sq. km, and about (80%) is available for various agricultural purposes including arable land, permanent crops, pastures, and irrigated land. However, to achieve the set goal in the past, a series of agricultural information dissemination strategies such as radio, television, and print media were employed to raise adequate revenue for the agricultural sector and increase the food supply in Nigeria via Agricultural Research Outreach Centre in the National Agricultural Extension and Research Liaison Services adopted villages/ schools. The study was premised on a mixed method for counterfactuals to facilitate novelties. Despite all the efforts, these strategies did not yield the desired goal, thus, the digital transformation of the agricultural sector particularly to strengthen the extension system in Nigeria. This manner, demands the integration of the agricultural sector into the digital hub to create synergy among the stakeholders, source requisite agricultural information, and hybridize the means of disseminating agricultural information via participatory learning and action platforms. Also, create a Digital Participatory Learning and Action for Agricultural Extension (Di-PLA4AE). Thus, the paper trail on the concept of AROC, ICTs - Digitization, x-rayed the Actor-Network Approach (ANA) by Callon, its application, and the implications of digitization for agricultural activities to stakeholders and criticism in the context. More so, mirror the implications of the Di-PLA4AE and conclusion.

The following is an abstract of the article. The article presents an analysis of the challenges associated with monitoring and managing the scalability of a cloud application. To this end, a module for monitoring and managing the scalability of a cloud application has been developed as part of this study. The development process included the introduction of automatic scaling, and monitoring using Prometheus and Grafana, which allows for a high level of availability and resource efficiency. The study comprised a series of phases, including requirements analysis, system design, development, testing, and evaluation. Consequently, the system's performance, stability, and capacity to scale in response to fluctuating workloads were enhanced. The module exhibits a high degree of adaptability to changes in system requirements and load, which is a crucial attribute for the dynamic development of business applications. This solution assists in optimizing the allocation of resources and reducing infrastructure costs. The project has been found to fully meet the set goals and objectives, as well as the requirements for effective resource management of the Amazon Web Services cloud platform using Terraform, Prometheus, and Grafana. The practical value of the developed module is evidenced by a significant improvement in resource efficiency, service stability and cost optimisation. The module design has been subjected to rigorous testing and has been successfully implemented in a test environment, thereby demonstrating the sustainability and efficiency of the developed solution. The experience gained in the implementation and operation of this solution may prove useful for further expansion and optimization of cloud solutions in other projects and companies specializing in the provision of cloud solutions. The findings of this study were validated in a test environment at an IT company with a specialization in cloud technologies. The objective was to ascertain the functionality and efficiency of the developed module in a real-world context of cloud infrastructure operation. The testing process entailed the configuration of the module on pre-existing cloud infrastructure systems, its integration with Prometheus and Grafana for monitoring purposes, and the execution of a series of stress tests designed to assess the module's scalability. As a result of this testing, a number of critical points were identified that required further optimization. The results of the study and the issues identified during the project testing have enabled the identification of several areas for further improvement and development of the system. First and foremost, the optimization of automatic scaling algorithms represents a crucial avenue for improvement. The development of these algorithms should be oriented towards utilizing historical monitoring data to anticipate potential shifts in system load. Another pivotal area for enhancement is the precision of monitoring systems. The integration of supplementary tools and the expansion of existing monitoring systems' functionality will facilitate the acquisition of more comprehensive insights into the system's condition. This, in turn, will facilitate the expedient identification and eradication of potential issues.

Художественные практики современных российских немцев в контексте традиций и новаций: на примере программы фестиваля культуры «Немецкая Слобода» (2015–2022 гг.)

The subject of research in this article is the artistic practices of modern Russian Germans, implemented within the framework of the cultural festival “German Sloboda”. It is proved that festival artistic practices belong to the “culture of ethnos” (according to V. G. Babakov’s classification), that is, they are a combination of ethnic and externally introduced components. The latter are the artistic practices of postmodernism, such as performance, happenings, environment and their varieties. The scientific novelty of this work is the consideration of the traditional culture of Russian Germans in the context of artistic forms, methods and techniques of modern times. The objectives of the work include: an analysis of the artistic practices of the cultural festival of Russian Germans “German Sloboda” from the point of view of correlating ethnic content and modern forms of its presentation, as well as the development of the above-mentioned artistic practices in the history of the festival. To achieve the set goals and objectives, a historical-genetic method is used, which allows us to trace the relationship between ethnic traditional and modern innovation in artistic practices, as well as a structural-functional method that demonstrates the artistic practices of modern Russian Germans as an integral part of their spiritual culture. As a result of the analysis of the artistic practices of the cultural festival of Russian Germans “German Sloboda”, a conclusion is made about the culture of modern Russian Germans as a synthesis of the immanent and transcendent, as a combination of following the sociocultural experience of previous generations – traditions – and the desire of the current generation for changes – innovations. The “culture of ethnos” of modern Russian Germans is in the stage of modification and transformation of its forms, creative experimentation, search for an individual-personal beginning with constant reliance on the collective traditional experience of the past. The seven-year history of the cultural festival of Russian Germans “German Sloboda” clearly demonstrates the active use of postmodern artistic practices, in which art leaves traditional spaces (galleries, museums, concert or theater halls) and conquers new spaces that are not necessarily associated with art.

Constitutional and Legal Foundations of Interaction Between the State and Civil Society in Ensuring the Protection of State Sovereignty and Territorial Integrity of the Russian Federation

Introduction. The relevance of the study is caused by three main factors. First, there is the need for further in-depth scientific and legal analysis of the amendments 2020 to the Constitution, which contain a number of fundamentally new provisions for domestic constitutional legislation that consolidate the legal foundations for ensuring the protection of state sovereignty and territorial integrity of the Russian Federation. Secondly, the undoubted interest of the Russian state in modern conditions in the development of civil society in Russia as a whole, and in particular its individual institutions that have a direct impact on the activities of the state in this area, as well as the understanding that in modern conditions only with the support and active participation of civil society in the policy implemented by the state In the field of protection of state sovereignty, it is possible to achieve the set goals and objectives. Thirdly, the difficult geopolitical situation that the Russian Federation has been in for the past ten years, striving to preserve state sovereignty and prove its belonging to one of the leading countries of the world under unprecedented pressure from the collective West. Theoretical Basis. Methods. The theoretical basis of this study is made up of scientific works of scientists in the field of the theory of state and law, constitutional law, administrative law. The work uses general scientific methods (system analysis, dialectical, formal-logical) and special research methods (system-legal, comparative-legal, historical-legal, formal-legal). Results. Firstly, based on the supremacy of national sovereignty over state sovereignty, the need to strengthen the latter through the development of institutions (elements) of civil society, which carry out certain types of relevant public (socially useful) activities provided for in legislation in this area, is justified. Secondly, the requirements imposed on the institutions of civil society, called upon, especially during the period of a special military operation, to carry out activities aimed at strengthening the state sovereignty of the Russian Federation, are highlighted. Thirdly, a scientifically based conclusion has been made that the term “civil society” to a greater extent than the legal category “people” emphasizes the presence of common interests among citizens of the Russian Federation, awareness of their constitutional rights and freedoms and opportunities and desire to carry out, especially during the period of a special military operation, public (socially useful) activities, including those aimed at ensuring state sovereignty. Discussion and Conclusion. In the context of further increasing threats to the state sovereignty and territorial integrity of the Russian Federation, there is a need to consolidate civil society in the current legislation as a source of democracy and the basis of the constitutional system, its formation as a public law institution designed to be the natural support of the state, to perform appropriate functions in the field of patriotic, including military-patriotic education of citizens of the Russian Federation Federations, as well as stabilizing functions that allow consolidating the interests of the state and society, using its full potential to protect national interests.

Довкіллєве правосуддя в Україні та світі

The article is devoted to the study of domestic and foreign trends in environmental justice. To solve the set goal, the following research methods were used, in particular: the method of scientific observation is to form the topic and purpose of the research; comparative legal method in the study of foreign experience of environmental justice; logical method – for theoretical generalization and formulation of research conclusions. The main models of environmental justice that exist in the world include such as consideration of environmental cases by courts of general jurisdiction, consideration of environmental cases by judges specializing in environmental issues or specialized environmental divisions of courts, consideration of environmental cases by specialized environmental courts. Environmental courts, as specialized judicial authorities, deal with the resolution of environmental conflicts and the protection of the environment and function in particular in countries that are members of the European Union, such as Sweden and Austria. In Ukraine, environmental justice is carried out in the form of civil, economic, administrative and criminal proceedings. At the same time, civil, economic, administrative and criminal cases in the environmental sphere differ among themselves in terms of the type of offense, the subject of the dispute, the composition of subjects, etc. Judicial practice in the environmental sphere covers a wide range of environmental relations, in particular on atmospheric air protection, land protection and use of land resources, subsoil protection and use of minerals, protection of forests and use of forest resources, protection and use of territories and objects of the nature reserve fund, access to environmental information, waste management, etc. Environmental justice in Ukraine may be limited to the functioning of certain specialized environmental units in courts, or involve the formation of a system of specialized environmental courts throughout the country, including a higher specialized court. At the same time, the implementation of environmental justice will be more or less time-consuming and costly (depending on the model chosen for implementation).

GLOBAL EXPERIENCE OF DEVELOPING COUNTRIES IN FORMING INNOVATIVE MECHANISMS OF GREEN ECONOMIC GROWTH

The article examines the international experience of developing countries in creating and implementing innovative mechanisms to achieve green economic growth. The necessity of implementing such mechanisms to ensure sustainable economic development is substantiated. It is argued that innovative approaches are key to preserving the ecological balance and improving the well-being of the population. It was established that the effective use of natural resources requires the integration of environmental and economic strategies. Based on the set goal, various models and practices of green growth applied in developing countries are considered. Successful examples are studied and found that their adaptation can contribute to global sustainable development. Further perspectives of research should be aimed at studying the possibilities of scaling and optimization of these innovative mechanisms in the context of global challenges. It was determined that each country has its own characteristics due to the level of development of the country, its geographical location, the presence of natural resources and the specifics of the concepts, models and development tools used, which correspond to national priorities and accumulated experience, and therefore the transition to a "green" economy for different states will take place under different scenarios. It illustrates the benefits and challenges of implementing green innovation for developing countries using the example of China and its chart of China's key industrial strategies for green manufacturing. During the research of this topic, it was found that the consistent and effective implementation of the principles of "green" investment, as well as "green" development in general, is possible only in a regulatory environment, transparent and fair, developed in accordance with the principle of the rule of law, with independent courts procedures, with the participation of independent market regulators acting in accordance with national interests, respecting the rights of investors and consumers. On the other hand, for their principles of implementation a vital role is played by socially responsible business behavior, one of the key indicators of which is the attitude of business to environmental issues, the efficiency of resource use and energy efficiency, and the disclosure of socially significant non-financial information. It is noted that in Ukraine climate and investment policies function separately from each other, and sometimes their goals are mutually contradictory, which prevents or slows down investments in the development of "green" infrastructure.

THEORETICAL BASIS FOR THE DEVELOPMENT OF CIRCULAR ECONOMY IN UKRAINE IN THE CONTEXT OF EUROPEAN INTEGRATION

The article reveals the impact of European directives and policies on the development of the circular economy in Ukraine. In particular, the "Circular Economy Action Plan" and the EU Waste Directive, which serve as guidelines for adapting Ukrainian policy to European standards, are considered. The role of the EU in supporting Ukraine on the way to the implementation of circular practices is considered. Possibilities of cooperation with European partners to ensure sustainable development were explored. It is argued that the development of the circular economy contributes to reducing the level of waste and increasing the efficiency of resource use. The connection between European directives and national policy in the field of sustainable development is established. Based on the set goal, the key directions and mechanisms for adapting the principles of the circular economy in Ukraine are considered. The paper examines the impact of Russian aggression against Ukraine and establishes that each community needs the formation of a new management system, which should be aimed at their reconstruction and integration into the European Community on the basis of sustainable development, restoration of critical infrastructure, and energy security. Therefore, the expediency of developing the project of the Strategy for the Green Reconstruction of Territories on the basis of subsidiarity and taking into account the European Green Course is substantiated. The specified strategy must meet the Sustainable Development Goals of Ukraine until 2030 and be based on the planning system: state strategy - regional strategy - community strategies. Examples of successful implementation of circular practices in various countries and enterprises are highlighted. The article calls on the Government of Ukraine to actively implement circular principles in the country's economy in order to achieve greater sustainability, resource conservation and promote environmental responsibility in this important industry. Attention is focused on the fact that when forming a new model of the circular economy, it is necessary to take into account and connect the development of ecological innovations and, accordingly, the ecological economy.

CONCEPT FOR THE DEVELOPMENT OF A GREEN URBAN ECOSYSTEM: MAIN THEORETICAL APPROACHES

The article reveals the basic theoretical approaches to the formation of a green urban ecosystem in the conditions of modern urbanization. The importance of ecological planning in cities and the impact of green spaces on improving the urban environment are substantiated. The necessity of introducing new methods of managing urban ecosystems, taking into account modern environmental challenges, has been established. Based on the set goal, modern approaches to planning and management of green infrastructure are considered. It is argued that the integration of natural components into urban structures is a key prerequisite for the sustainable development of urban areas. The main principles of creation and maintenance of the urban ecosystem were studied, in particular in the context of adaptation to climate change. The main trends in the development of green spaces in cities have been determined. Further perspectives of research should be directed to the integration of innovative solutions to improve the ecological condition of urban areas. The article also discusses the concept of urban ecosystems and what functions they perform. The latest scientific studies on the growing interest in the problems of green infrastructure development in cities were analyzed. Fifteen principles of green urbanism are analyzed in detail and examples of how they are implemented in some countries of the European Union are given. It is proved that the implementation of the concept of "green" economy is possible only if state mechanisms are introduced to encourage investment in environmentally safe production. Attention is focused on the need to change the methods and forms of fiscal policy at the government level, adopt appropriate laws and regulations, radically reform the policy of subsidizing and supporting renewable energy sources, and further increase investment in the "green" sectors of the economy. It is shown that the development and implementation of the concept of "green" economy in Ukraine should be considered as the main reference point and the basis of state policy. To improve environmental safety in the capital, it is necessary to consistently implement a range of organizational, technical, innovative and other environmental measures with mandatory definition of the social optimum of environmental quality, which will be accompanied by increasing environmental costs and significantly increasing society's requirements for economical use.

The use of fractal analysis to assess the influence of electrospark alloying on the durability indicators of hydraulic hammer parts

Abstract. Statement of the problem. In order to increase the wear resistance and fatigue strength of the material of hydraulic hammer parts, it is not always advisable to change the traditional technology of manufacturing the part and, in particular, the methods of its heat treatment. Different types of finishing are applied only specifically to the given product. In some cases, it is worth applying surface strengthening of the product. Purpose and problem statement. The purpose of the work is to evaluate the impact of electrospark alloying on the durability indicators of hydraulic hammer parts. In order to achieve the set goal, it is necessary to: develop modes of electrospark alloying; conduct an analysis of the location of damage zones and their nature on parts strengthened by electrospark alloying, identical to those observed on tested parts manufactured without additional strengthening and with the use of LTO; Apply fractal analysis to evaluate the impact of electrospark alloying on the durability indicators of hydraulic hammer parts. Research material and methods. All details were strengthened by electrospark alloying with tungsten. The power of the processing current was 1 kW. The peak, in addition to strengthening with tungsten, was additionally processed by electrospark alloying with chromium at a current of 1.5 kW. The surfaces processed by electrospark alloying were ground to obtain the roughness of the strengthened surfaces of parts R and 04–08. Experimental results and their discussion. During the micro-examination of areas strengthened by electrospark alloying, which are outside the load zone during the test, it was established that the areas strengthened by electrospark alloying on the body and sleeve have a thickness of 10–40 μm and a hardness of Н V 600–650. On the strikers, the initial thickness of the hardened layer is 20 μm with a hardness of НV 600–650. The strengthened zones in the cross-section have the appearance of arc-shaped, embedded surface layers of metal parts, phases. There are no structural changes under this zone in the main metal. Conclusions. The results of tests of parts strengthened by electrospark alloying show that the wear resistance of the parts is increased by 1.3 times compared to the original state of the parts. Fractal models were obtained, which can be interpreted as a knowledge base for monitoring the strength indicators of the striker body, which allow monitoring its residual resource during operation. It was established that the strength indicators increase when the fractal dimension of the sorbite component increases, since it has better strength indicators compared to the original ferrite-pearlite structure. Indicators of pairwise correlation coefficients of the obtained models are fixed in the interval of values 0.6779...0.9254.

Abstract. Statement of the problem. Regarding the implementation of the stage aimed at determining the field of trade-off of the properties of the mechanical properties for the material of the studied rolls, it should be noted that most of the criteria characterizing the workability and efficiency of the technology are set by the State Technical Service of Ukraine, state technology and other regulatory documents within permissible limits. These regulatory documents are intended to support the technological process in the optimal working zone of parameters, which allows to achieve the maximum possible productivity and product quality. Purpose and problem statement . The goal is to develop a method for evaluating and controlling the mechanical properties of cast iron rolls depending on the influence of their chemical composition and structure. To achieve the set goal, it is necessary to develop and test a method of determining the area of compromise of the mechanical properties of cast iron rolls; implement the possibility of predicting the mechanical properties of the rolls by adjusting their chemical composition within the limits of standard technology; to achieve an optimal combination of mechanical properties σв, σзгин, KC and НСD, based on the defined limits of the content of the components of the chemical composition. Research material and methods. As a material for this study, cast rolled iron rolls of the SSHKHN design (a sample of 283 smelters with a total weight of 800 tons) were accepted. Modifiers (Foundrisil, Elmag-600, Elmag-900, Vl 57 (M), Barinoc, Elgraf) were used in the manufacture of rolls. Mechanical properties (σb, σbeяnding, KC and НSD) were determined for the working area of the barrels of cast iron rolls of the СШХН execution (up to 50 mm deep) with a smooth barrel on standardized equipment. Experimental results and their discussion. Based on the analysis of the results of active and passive experiments, using the grapho-analytical method, the areas with the most effective combination of mechanical properties for graded rolls (areas of compromise of quality criteria) were determined depending on their chemical composition and structure parameters. For rolls made of SSHKN, the area of compromise combines the areas of permissible values of each of the mechanical properties: σВ=240…460 МPа, σЗГИН=330…940 МPа, КС=9…33 кJ/m2, HSD=40…60, taking into account the entire range of applied cooling conditions in the metal form. Scientific novelty. The method of determining the area of compromise of the mechanical properties of cast iron rolls has been developed and tested. For the first time, a compromise zone was established, which provides the most effective combination of mechanical properties (strength limit σB, bending strength σbend, impact toughness CS and hardness HSD) for the working surface area of grade-rolled rolling rolls with spherical graphite alloyed with chromium and nickel (СШХН-41, СШХН-45, СШХН-47, СШН-50). This area is determined by the specific limits of the content of components, chemical composition and parameters of the structure, which includes the percentage of spheroidal graphite, lamellar pearlite and carbides Conclusions. The method of determining the area of compromise of the mechanical properties of cast iron rolls has been developed and tested. It is possible to predict the mechanical properties by adjusting the chemical composition of the rolls within the limits of the state-of-the-art technology. An optimal combination of mechanical properties σв, σzhyn, KC and НSD, based on the defined limits of the content of the components of the chemical composition, has been achieved.

Laying the Foundations for a Child-Focused Cities Analytical Framework: Reflections From an International, Interdisciplinary Collaboration

Children, a unique yet marginalized social group, hold immense potential for driving meaningful social and environmental change, both in their current lives and as future stewards of the planet. However, their significant contributions often depend on the mechanisms and opportunities adults create to facilitate their participation and inclusion. This places local governance at a crucial juncture, mediating children’s involvement in shaping their urban environments. This research was initiated by the Swedish International Centre for Local Democracy in 2022, gathering international scholars and practitioners to critically assess the “child-friendly city” concept. Through an interdisciplinary approach, the study sought to advance the notion from simply being “friendly” to a deeper commitment to amplifying children’s voices within social, physical, and relational spheres. The methodology transitioned from initial academic discussions to the creation of a comprehensive analytical tool, the “Child-Focused Cities Analytical Framework.” This framework aims to tackle the complex challenges of child participation, aligning with the Sustainable Development Goals (SDGs) in both local and global settings. This article unveils new insights at the intersection of children’s rights, the SDGs, and local governance, laying the groundwork for a model that prioritizes and enhances children’s perspectives, thereby catalyzing social and environmental progress.

Exploring the impact of accelerator programs on startup success: A focus on corporate collaboration and goal achievement

Start-up corporation collaboration is a phenomenon that is becoming more and more noticeable in the marketplace. Start-ups perceive such partnerships as an opportunity to scale up their solutions (products/services), while corporations open up to young companies to explore new business models. Understanding the collaboration goals is vital to secure collaboration benefits for each party. It seems interesting to find out to what extent this type of collaboration is critical to the start-ups, to what extent the corporate collaboration goals are defined, and if they are achieved. Therefore, diffusion of innovation theory and social network theory appear as a capable theoretical lens for analysing how 15 defined goals that start-ups use to guide them through establishing collaboration with corporations and verifying partnerships in the context of the adopted goals. The impact of the start-ups' experience on the perceived significance of the goals and their attainment level was examined. Moreover, a clear difference in the perception of expectations and the level of attainment of the set goals of partnership with corporations depending on the company development phase was highlighted, and it was presented how start-up awareness grows along with start-up development and the approach of start-ups to the studied variables changes.

Developing Self-Regulated Learners in Nursing.

Students who enter nursing programs without adequate study skills may be shocked when they fail their first nursing examination or assignment. If they continue to struggle, they may fail to progress to graduation or may perform poorly on their licensure examinations. Assignments based on self-regulated learning theory can help students develop control over their learning environment, establish effective study strategies, set goals, and prevent procrastination. Two assignments for students studying for a baccalaureate of science in nursing are presented as examples of activities that promote self-regulated behaviors: (1) Research Literature Search Assignment Strategies worksheet and (2) student-led examination reviews to prepare for an examination. Students' reactions to assignments are described. Integration of the principles of self-regulated learning can add value to active learning. Faculty with an understanding of self-regulated learning theory are better able to recognize student deficiencies and design assignments to help students succeed. [J Nurs Educ. 2024;63(X):XXX-XXX.].
