ПРИОРИТЕТЫ РАЗВИТИЯ ЭНЕРГЕТИЧЕСКОЙ ПОЛИТИКИ США В 2012-2023 ГГ

The shale revolution of the early 21st century has radically changed the energy image of the United States, turning the country into one of the largest exporters of hydrocarbons. Such significant transformations could not but affect how Washington positions itself in the global energy market and how it defines its national interests in this sphere. The article is dedicated to the juxtaposition between the approaches of the last three administrations to this issue. Despite the fact that a significant body of domestic and foreign research focuses on the persistent desire of each new political leadership to maximally distance itself from its predecessors, a consistent analysis of the strategic documents on the development of the U.S. fuel and energy complex, as well as on the specifics of building relations with other actors of the international energy system, allows us to make a conclusion that Washington’s policy is based on the constant imperative of achieving resource self-sufficiency and gaining a dominant position in the global market. Such a circumstance indicates the evolutionary nature of the changes in the 2012–2023 US energy doctrine, and it occurred in full compliance with the global leadership mentality which is typical for the country.

High mountain agriculture in Colombia: opportunities for conversion to sustainability

This review article presents a socioecological analysis based on current literature to provide elements to enrich the currentdebate on the transition to sustainability proposed in Law 1930 of 2018. to achieve this objective, a review of currentregulations and commitments of Colombia for sustainable agriculture is made, Afterwards, a review of high mountainecosystems and their importance with emphasis on agricultural and livestock activities is included. Subsequently, adescription of the different schools of agriculture present in high mountain ecosystems is included. Finally, a reflection ismade regarding the progress and challenges to achieve the transition of agricultural activities towards sustainability inmoorland ecosystems. It is concluded that, although there are advances in the political-institutional and socio-ecologicalframework, it is imperative to focus on all the actors of the Colombian agri-food system and make timely progress in therecognition and valuation of the contributions that the different schools of agriculture make to sustainability, usingcriteria that are proposed based on the dimensions of sustainability. Not including these elements in the debate turns thetransition into a sophism that will perpetuate socio-ecological conflicts in the territories.

Streaming Readout and Data-Stream Processing With ERSAP

With the exponential growth in the volume and complexity of data generated at high-energy physics and nuclear physics research facilities, there is an imperative demand for innovative strategies to process this data in real or near-real-time. Given the surge in the requirement for high-performance computing, it becomes pivotal to reassess the adaptability of current data processing architectures in integrating new technologies and managing streaming data. This paper introduces the ERSAP framework, a modern solution that synergizes flow-based programming with the reactive actor model, paving the way for distributed, reactive, and high performance in data stream processing applications. Additionally, we unveil a novel algorithm focused on time-based clustering and event identification in data streams. The efficacy of this approach is further exemplified through the data-stream processing outcomes obtained from the recent beam tests of the EIC prototype calorimeter at DESY.

MonARCh: an actor based architecture for dynamic linked data monitoring.

Monitoring the data sources for possible changes is an important consumption requirement for applications running in interaction with the Web of Data. In this article, MonARCh which is an architecture for monitoring the result changes of registered SPARQL queries in the Linked Data environment, is proposed. MonARCh can be comprehended as a publish/subscribe system in the general sense. However, it differs in how communication with the data sources is realized. Data sources in the Linked Data environment do not publish the changes in the data. MonARCh provides the necessary communication infrastructure between the data sources and the consumers for the notification of changes. Users subscribe SPARQL queries to the system which are then converted to federated queries. MonARCh periodically checks for updates by re-executing SERVICE clauses and notifying users in case of any result change. In addition, to provide scalability, MonARCh takes the advantage of concurrent computation of the actor model. The parallel join algorithm utilized speeds up query execution and result generation processes. The design science methodology is used during the design, implementation and evaluation of the architecture. When compared to the literature MonARCh meets all the sufficient requirements from the linked data monitoring and state of the art perspectives while having many outstanding features from both points of view. The evaluation results show that even while working under the limited two-node cluster setting MonARCh could reach from 300 to 25,000 query monitoring capacity according to the diverse query selectivities executed within our test bench.

What is public trust in national electronic health record systems? A scoping review of qualitative research studies from 1995 to 2021.

Public trust in national electronic health record systems is essential for the successful implementation within a healthcare system. Research investigating public trust in electronic health records is limited, leading to a lack of conceptual clarity. In response, the objective of this study is to gain a clearer understanding on the conceptualizations of public trust in electronic health records, which can support the implementation of national electronic health record systems. Guided by the PRISMA-ScR checklist, a scoping review of 27 qualitative studies on public trust in electronic health records found between January 2022 and June 2022 was conducted using an inclusive search method. In an iterative process, conceptual themes were derived describing the promoters and outcomes of public trust in electronic health records. Five major conceptual themes with 15 sub-themes were present across the literature. Comprehension, autonomy, and data protection promote public trust in electronic health record; while personal and system benefits are the outcomes once public trust in electronic health records exists. Additional findings highlight the pivotal role of healthcare actors for the public trust building process. The results underscore comprehension, autonomy, and data protection as important themes that help ascertain and solidify public trust in electronic health records. As well, health system actors have the capacity to promote or hinder national electronic health record implementation, depending on their actions and how the public perceives those actions. The findings can assist researchers, policymakers, and other health system actors in attaining a better understanding of the intricacies of public trust in electronic health records.

Assessing leverage points for strengthening adaptive capacity in a Global South food system: A psychometric approach

Despite the burgeoning literature on adaptive capacity, there is a lack of psychometric approaches for assessing the determinants of adaptive capacity, particularly in food systems in the Global South. The study addressed this knowledge gap by investigating four determinants, previously identified as leverage points, for strengthening adaptive capacity: access to finance, access to and use of information and knowledge, social learning, and gender equality. Drawing on a survey (n = 1,271) of food system actors in Kisumu County, Kenya, we conducted a confirmatory factor analysis, which yielded factors of moderate-high internal validity and reliability. We then used structural equation modelling to examine the causal effect of food system actors’ attitudes and beliefs towards the four leverage points with regards to their perceived adaptive capacity. Two factors, access to finance and social learning, were significant positive predictors of adaptive capacity. A third leverage point factor, gender equality, contributed to the respondents’ perceived adaptive capacity through the mediating factor of assets. The results reveal entry points for strategic adaptation planning and raise complexities related to gender norms and values. We discuss the implications of these findings for adaptive capacity and transformative adaptation theory in food systems in the Global South.

How to Ensure the Comprehensive Development of the Russian Innovation System

Effective functioning of The Russian innovation system (RIS) is impossible without forming an independent and systemic innovation policy. It should unite the interests of all participants in innovation activities and create effective incentives and institutions for developing the scientific, educational and business environment. The study aims to identify the primary recommendations for reforming and implementing economic policy in the field of innovation formulated by the actors of the Russian innovation system (representatives of business and academia). The authors applied an economic narrative analysis approach, which studies the semantic characteristics of the narratives told by actors in the innovation system. The empirical basis of the study consists of scientific works on national innovation systems, as well as 27 interviews with representatives of the academic sphere and 26 interviews with business representatives. Based on the narrative analysis of innovation systems, the authors formulated proposals and strategic recommendations for the implementation of innovation policy aimed at enforcing effective measures for the integrated and progressive development of the RIS: adoption of a unified federal law on innovation to determine the direction of development of the RIS; creation of a unified federal information platform to ensure effective and accessible communication between entrepreneurs and representatives of the academic sphere; reducing institutional barriers to the implementation of innovative activities in Russia; stimulation of demand for innovation and innovative activity; application experience of other countries to adapt to new challenges in priority areas of development.

Analisis Kebijakan Pemberian Bantuan Militer Amerika Serikat kepada Ukraina Selama Masa Invasi Rusia 2022

This study aims to analyze the policy of providing United States military assistance to Ukraine during the 2022 Russian invasion. The policy of the United States deciding to provide military assistance to Ukraine to help Ukraine resist the Russian invasion drew reactions from the international community as well as from Russia itself. This study aims to analyze this in the context of: exploring the types of assistance, the reasons & objectives behind policy making, and their implications for the relationship between the United States and Russia. This study will use the Rational Actor Model Theory to analyze the reasons behind the policy of granting military to Ukraine by the United States which has considered all available viewpoints, alternatives, and solutions so as to achieve the highest objectives of the policy. In looking at the goals to be achieved by the United States in policy making, the concept of national interest will provide insight into what the United States’ intended goals behind their policy of providing military assistance to Ukraine. The results indicate that the given aid is an investment whose benefits outweighs its costs, as well as the United States justifying their aid provision to Ukraine under defense, ideological and economic interests

Economic behavior of agricultural land market subjects

The purpose of the study is to build the agricultural land market subjects’ economic behavior models. The formation of rational land use in the agrarian sphere indicates influence of institutional factors – motives and interests of land owners that allow to ensure land distribution included in the market turnover between the most efficient users. The structural scheme of the agricultural land market subjects’ behavior motives has been proposed. The motives of sellers in the land market are to optimize income that is achieved by increasing a land plot attractiveness. Buyers are guided by the possession motives, use and disposal of land by acquiring a land plot. Sellers and buyers of land plots are individuals and legal entities. Agricultural organizations, individual entrepreneurs, farms, personal subsidiary plots, and citizens (rural population) participate in land sailing. Buyers in the market are owner, land user, landowner, and tenant. The functions of sellers and buyers have been systematized considering the purpose and action of the actors. Destructive and rational models of the agricultural land market actors’ economic behavior have been presented and developed. The application of the destructive model is associated with negative consequences characterized by land withdrawal from economic turnover, change of its intended purpose, and land transfer to another category. The rational model includes finding an optimal alternative under a set of constraints and provides for a high level of human intelligence and knowledge to make right decisions. Factors of this model are coordination of land ownership institutions and creation of a legal framework. It is characterized by strict administrative and legal regulation that contributes to eradication of shadowing in land relations. The area of application of the developed rational model of the agricultural land market subjects’ economic behavior is scientific organizations, agro-industrial complex management bodies at the regional and municipal levels, and agricultural producers.

Sustainability potentials of digitally based platforms for the circularity of household items

Closed-loop supply chains (CLSCs) are an important response to pressing sustainability challenges. However, they bring about tradeoffs like increased resource use in logistics. Addressing these complexities, digital platforms emerge as promising, yet under-researched, tools for efficiency enhancement in CLSCs. This study investigates three digital platforms facilitating furniture and household item trade in relation to CLSCs. A comprehensive framework, rooted in literature on CLSCs, digital platforms, and logistics, guides the analysis. The findings reveal diverse sustainability potentials within these platforms, primarily driven by system design, scale, and actor engagement. The efficacy of the digital platform varies based on usage patterns, their geographical scope, logistic solutions, and providers. Crucially, environmental and social sustainability tradeoffs and benefits come to light, offering insights into their emergence based on system design. This study provides insights for practitioners and scholars, regarding potentials/risks of trade-offs in environmental and social sustainability dimensions related to the use of digital platforms for trading secondhand furniture. It provides a nuanced understanding of how these differ depending on system design.

Modeling the maturation process of high performance-oriented child athletes

The article considers the problem of growing up of individuals in the sports field of activity aimed at achieving high sports results. Based on the theoretical developments of researchers N. V. Veselkova and E. V. Pryamikova, aimed at identifying the social nature of maturation competence, as well as the author's sociological study «Longevity in high-performance sports», carried out by the method of questionnaire survey of high-class athletes (n=400 people, the sample "snowball"), theoretical and applied research of modeling the maturation process of child athletes aspiring to become high-performance athletes was carried out. Modeling of the process of maturation of this category of population was carried out in two directions: first, the influence of external conditions on the process of maturation - the environment in which the individual is formed; circumstances in which the individual is forced to be and their perception; subjects surrounding the personality and their direct influence on it. Secondly, the influence of internal characteristics of the individual - internal qualities, personality traits, the dominant of which is the ability to cognize oneself, which allowed us to form an internal and external model of growing up. The external model of growing up in the sphere of sport is characterized by a high level of social influence on the subject, contributing to the formation of social thinking in young athletes. The internal model of maturation develops the subjectivity of young athletes to a greater extent, which is facilitated by the process of goal-setting of actions, a high level of responsibility to society for the achieved result. The aggregate of the actor's subjectivity and his social thinking form the internal-external model of actors' maturation in the sports sphere of activity, which allowed the athlete to achieve a high level of sports results.

Labor markets for health supply chain management in Rwanda: a qualitative study of stakeholder perspectives

BackgroundEffective supply chains for health products require an adequate, skilled workforce for supply chain management (SCM). Rwanda faces challenges in human resources for SCM, including limited capacity for SCM at different levels. Understanding of the factors influencing the supply of and demand for SCM professionals in Rwanda is necessary to ensure the labor market contains an adequate workforce. This study identifies the perspectives of key stakeholders in the supply chain management sector about the factors influencing the supply of and demand for SCM professionals.MethodsData were collected in semi-structured group and one-on-one interviews with 39 key stakeholders involved in the supply chain management labor market between March and April 2019. Interviewees were categorized according to their role in the labor market as system actors, functional actors involved in the supply of SCM workers, and functional actors involved in the demand for SCM workers. Interviewees were asked open-ended questions about factors influencing the demand for and the supply of SCM workers, and recommendations for improvement. Interviews were analyzed thematically. One validation focus group was held and the results were also reviewed by the Ministry of Health in Rwanda.ResultsStakeholders agreed that skills mismatch between SCM workers’ skills and the competencies jobs require impacts the supply of workers. A lack of career structure for SCM, lack of professional definitions for health supply chain management, and SCM curricula that do not match the needs of the workplace contribute to this gap. The demand for SCM professionals is poorly defined in terms of the numbers of professionals needed and the skills workers require. Financial limitations hinder demand for health SCM professionals.ConclusionsThis study adds to the understanding of factors influencing the SCM labor market in Rwanda by documenting perspectives from government ministries, professional organizations, universities, and employers from SCM organizations. Improving the SCM labor market in Rwanda and the availability of the skilled cadres required for the effective management of health supply chains in Rwanda requires a coordinated effort by the Ministry of Health in Rwanda, private SCM companies, professional associations, education sector, and policy makers.

Between farms and forks: Food industry perspectives on the future of EU food labelling

This study assesses how information about the provision of ecosystem services can contribute to an integrative food labelling framework within the European Unions' Farm to Fork Strategy. By applying Q-methodology with 43 food industry experts from four European member states – Germany, Poland, Spain, and Sweden –, we identify common viewpoints among food processors, retailers and labelling organisations. We find a consensus in support of introducing new food labels that would encourage farmers to deliver more ecosystem services, such as increased farm biodiversity. Applying factor analysis and using the qualitative information from the interviews, we derive three distinct prototypes of a future European food label: 1) a producer-driven ecosystem services label, 2) a consumer-oriented information label, and 3) a new EU sustainable food label. These label prototypes are partly country-specific and invoked by multiple stakeholder groups. We conclude that a future European Union food labelling framework must account for all three label prototypes. Policymakers are advised to embrace the diversity of viewpoints of food system actors, as they are the main drivers of the success and failure of labels.

Reconceptualizing the Politics-Administration Dichotomy to Better Understand Public Leadership in the Twenty-First Century: A Multilateral Actors Model

The long-standing discussion of the politics-administration dichotomy is as relevant in contemporary public administration as at any time in the past. The significant changing context and persistence of the discussion on the practice of the politics-administration dichotomy calls for addressing what Overeem observes as the need to better describe the highly complex relations between politicians and administrators. Two implicit assumptions drive the continued relevance of the discussion of political-administrative interactions. First, the discussion matters because the actors in question fulfill various public leadership roles. Second, the political-administrative dialogue matters to questions of constitutionalism, values of representative government, and facilitating institutions of democracy. In this article, we offer a model of public managers’ engagement in the “how” with a framework that explicitly outlines the range of relationships. We draw on empirical research to outline the current reality of at least five significant types of actors, often working collaboratively in multilateral relationships. The first section of the article discusses the genesis and implications of the politics-administration dichotomy. It then proceeds to establish its persistence over time, followed by an explanation of the logic of our approach. Next, the discussion shifts to the analytic advantage of a continuum model across five categories of actors within the governance process, each possessing the potential for public leadership, showing how this model illustrates paths for addressing the problem we have identified. Finally, we discuss the implications of our proposed model for future research design and practice.

The third mission in brazilian federal universities: an analysis of their impact for the culture and associated actions to the sustainable development principles

The concept of Development as synonym of Economic Expansion has been attacked frequently and deeply. Governments, social groups, intellectual and educational circles are questioning and being questioned about the future. Natural resources have been explored and exploited in a massive path, in a platform that combines technology and capital. In the middle of this discussion, innovation comes to light as the main engine of this development. In another dimension, Universities, relevant actors in the innovation systems, expand their activities to fulfil their Third Mission, beyond the first, Teaching, and second, Research, which means the development of their environment, including Sustainability. So, the question of this paper is if Third Mission and Sustainability are autonomous and opposed concepts to solve the economic, social and environmental problems. The proposition is to point the grade of interrelation between the concepts while development tools of society. The investigation, as an exploratory study, evaluates the intensity of internalization of the Third Mission and Sustainability concepts in the Brazilian federal public universities. Supported by a relevant literature review, the analysis axes were defined. In addition, a review of strategic plans and actions completed the map. A case study added empirical evidence. Results point that universities use the third mission concept. The relationship university- third mission – sustainability has solid links in the Brazilian public universities, which include the themes in their strategic plans. The conclusion of this paper is that Third Mission and Sustainability are not opposed but even embedded concepts.

Explaining conflict violence in terms of conflict actor dynamics

We study the severity of conflict-related violence in Colombia at an unprecedented granular scale in space and across time. Splitting the data into different geographical regions and different historically-relevant periods, we uncover variations in the patterns of conflict severity which we then explain in terms of local conflict actors' different collective behaviors and/or conditions using a simple mathematical model of conflict actors' grouping dynamics (coalescence and fragmentation). Specifically, variations in the approximate scaling values of the distributions of event lethalities can be explained by the changing strength ratio of the local conflict actors for distinct conflict eras and organizational regions. In this way, our findings open the door to a new granular spectroscopy of human conflicts in terms of local conflict actor strength ratios for any armed conflict.

Abstract C109: Identifying implementation strategies to support cervical cancer screening programs in resource-limited countries through participatory action research

Abstract Background: Improving the adoption and integration of cervical cancer screening programs in resource-limited countries requires engaging with many local health system actors. We hypothesize that participatory design workshops co-developed by researchers, health system practitioners, and policy makers, facilitate rapid engagement to identify context-specific priorities and tailor strategies to improve implementation processes. Methods: With the Peruvian Ministry of Health (MOH), we co-designed a week-long workshop with health system actors (planners, providers, lab technicians) from the North District of Lima city. Through facilitated dialogue, participants engaged in self-reflection to map the cervical cancer screening and follow-up system, visualize system barriers, and identify potential solutions. As research partners, we analyzed findings from the workshop using the Consolidated Framework for Implementation Research, a framework from implementation science that identifies multilevel contextual factors that influence program implementation and guides the tailoring of strategies for improvement. Results: We identified three key context-specific challenges including 1) power hierarchies between specialists and midwives that obstruct the efficiency of screening services, 2) the complexities around communicating screening results, appointments, and referrals, are burdensome for patients and cause loss to follow up, and 3) implementation plans are not adequately matched to resources and workforce capacity. We identified feasible implementation strategies to address these challenges including 1) develop relationships between midwives and specialists through facilitated discussions to surface assumptions and align screening goals, 2) co-create counseling tools to help patients understand results and follow up steps for early detection and treatment of precancerous lesion that also reduce patients’ burden, and 3) Apply design workshops with key actors to develop an implementation plans to guide processes, acceptable adaptations, clinical workflows, and planning (ordering tests, supplies, training human resources, etc.) to align goals to prevention objectives and resources. Conclusions: Engaging with health systems actors through participatory action research is a strategy that enables collective learning, identifying context-specific priorities, and developing tailored implementation strategies that are likely to accelerate integration of sustainable cervical cancer screening programs globally.

Analysis of Stakeholders in Social Entrepreneurship Development

Stakeholders have an essential role in the development of social entrepreneurship (SE), so it is necessary to understand the role and contribution of stakeholders. Stakeholders referred to in the development of SE are parties involved and interested in the success and sustainability of SE. This research was conducted with women social entrepreneurs in the Greater Jakarta and Central Java Provinces. This study aims to discover the role of actors in developing SE in the Greater Jakarta and Central Java Provinces. The MACTOR analysis method is used in this study; this method includes determining system actors, setting goals, describing power relations, and assessing attitudes and the importance of dreams for actors. The analysis results are presented through graphs and figure, providing insight into actor competitiveness, alliance patterns, possible conflicts, and actor support for developing SE in the Greater Jakarta and Central Java Provinces. The study results show that policy is the central government; in this case, KEMENKOP UKM (MINISTRY OF COOPERATIVES AND SMES), UKM (Ministry of Cooperatives and SMEs), and KEMENSOS (MINISTRY OF SOCIAL AFFAIRS) (Ministry of Social Affairs) are vital in setting special SE regulations. The existence of rules issued by the central government will help social entrepreneurs get various social supports that are useful for developing SE.

The effect of COVID-19 containment measures on fresh food market vendors in Uganda

PurposeThe coronavirus disease (COVID-19) pandemic continues to impact economic systems, with devastating consequences on livelihoods. Anecdotal evidence has predicted the adverse effects of COVID-19 on the livelihood of food system actors. Uganda experienced two lockdowns in March 2020 and June 2021 with varying government containment measures. During the first lockdown, fresh food market vending was deemed essential to meet urban food demand, and was consequently exempted from a total shutdown despite the ban on public and private transport. Thus, this study sought to examine the effect of COVID-19 containment measures on fresh food market vending businesses in Uganda.Design/methodology/approachUsing primary data collected from fresh food market vendors, this study applied a pooled time-series estimation to examine the effect of the first lockdown COVID-19 containment measures on fresh food vendors' welfare.FindingsThe study revealed that COVID-19 had a significant negative impact on the income of fresh food vendors, with female vendors being the most affected. COVID-19 containment measures reduced the diversity of buyers, individual customers and the number of commodities traded in causing a greater impact on vendors' income.Research limitations/implicationsThe unavailability of data for vendors who did not return to the market at the time of data collection limits the scope of the study. Additionally, the absence of data for the second lockdown limited the analysis to only March 2020 lockdown period.Originality/valueThe empirical analysis highlights how vulnerabilities of different gender categories could be exacerbated by crises. The study provides empirical evidence of various market distortions caused by the COVID-19 pandemic and the disproportionate impact on women and men market vendors which calls for the need to integrate women's perspectives in future planning for market systems as well as advocating for gender-sensitive recovery responses.
