The paper describes UIC methodology and a technique used by Slovakian infrastructure managers for estimating railway capacity and proposes a new approach to evaluating the capacity consumption of a track line (occupation time) based on the graphic approach. The new methodology concerns for the assessment of infrastructure occupation time and is a conceptual framework developed by the authors for an easier evaluation of occupation time in the train traffic diagram.

A variety of methodologies are being used across Europe for the estimation of railway infrastructure capacity. This paper introduces the basic principles of the methodologies used – analytical methodology (e.g. Slovak railways), UIC methodology, and the graphically developed methodology of the Department of Railway Transport, University of Žilina (KŽD). On the basis of these new approaches, the occupation time estimation is researched. This new method is based on a graphic approach that uses operational time intervals as part of occupation time in accordance with the Slovak methodology. The new methodology concerns graphic capacity estimation and is a conceptual framework developed by the authors for easier evaluation of occupation time in train traffic diagrams.

AbstractProspero Balbo, the head of a leading Piedmontese noble family, followed a career path similar to that of the versatile French statesman Talleyrand. In the aftermath of 1789, Balbo served under four different regimes: the Old Regime monarchy, the Russian provisional administration of Piedmont in 1799, the Napoleonic empire, and the restored Savoy monarchy. After the short-lived revolutionary movement of 1821 in Sardinia-Piedmont, Prospero lost his job as interior minister and his son, Cesare, was forced into exile. The revolutionary waves of 1820–1821 were the most recent of numerous disruptive events and regime changes that jeopardized Europe and the Atlantic world between the late 1770 s and the early 1820 s. These five decades of revolutionary upheavals, wars, and persistent insecurity forced the traditional elites to mobilize their material, cultural, and social resources to preserve their prestige and power. Based on extensive archival research, this article examines the resilience-strengthening resources and strategies implemented by members of the Balbo family during periods of political turmoil. In doing so, the article aims to develop an analytical and conceptual framework to describe historical processes in terms of resilience and vulnerability. This new approach enables us to look afresh at elite transformations and at the dynamics of political change and continuity in early nineteenth-century Europe.

A new approach to immunizing our forests against uncertainty (essay) In the present context of global change, managing our forests is a major challenge, in particular because of the great uncertainty associated with this change. Faced with this new reality, our methods of monitoring and forecasting the developments in our forests are no longer effective enough, so we have to review how we manage our forests. Complexity theory provides a conceptual framework for our approach, which leads us to adopt a more holistic and flexible way of seeing the world when planning our forest management. We must therefore accept that forests are complex and dynamic systems, and for that reason, never completely predictable. By incorporating the functional properties of trees and the complex spatial network of their populations in our forest management, and encouraging greater functional diversity and connectivity, we can immunize the forests against present and future stresses.

Purpose The purpose of this paper is to counter-propose a new approach of SWOT analysis, which can be used in the strategic planning of the contemporary organizations. Design/methodology/approach This paper, after presenting the conceptual context of the existing (conventional) SWOT analysis, presents the existing criticism within the international literature. Then, it articulates gradually the new evolutionary and correlative SWOT analysis, by using the approaches and the literature of evolutionary economics, and the Stra.Tech.Man approach in business dynamics. In conclusion, it presents the new conceptual framework on which a new correlative SWOT analysis can be based. Findings Main finding of this research is that the interpretation of the conventional SWOT analysis tends to study the strengths and the weaknesses of the business with an analytical dichotomy. The conventional SWOT analysis conceptualizes, usually implicitly, the opportunities and threats of the external environment as having the same impact to all the socioeconomic agents, without exception. However, by using a correlative interpretation of SWOT analysis, we understand that the opportunities and threats are always “potential,” depending on the organization’s strategic capability to exercise its comparative strengths and weaknesses. Originality/value In the existing literature of SWOT analysis, despite the growing criticism, there is no critique that can give systemic and correlative answers to the articulation of business strategy in SWOT terms. The Stra.Tech.Man approach, also, is a conceptual framework to study the evolutionary adaptation of all the kinds of socioeconomic organizations.

<p>The aim of this study is to contribute to the field of machine-processable bibliographic data that is suitable for the Semantic Web. We examine the Entity Relationship (ER) model, which has been selected by IFLA as a “conceptual framework” in order to model the FR family (FRBR, FRAD and RDA), and the problems ER causes as we move towards the Semantic Web. Subsequently, while maintaining the semantics of the aforementioned standards but rejecting the ER as a conceptual framework for bibliographic data, this paper builds on the Resource Description Framework (RDF) potential and documents how both the RDF and Linked Data’s rationale can affect the way we model bibliographic data.</p>In this way, a new approach to bibliographic data emerges where the distinction between description and authorities is obsolete. Instead, the integration of the authorities with descriptive information becomes fundamental so that a network of correlations can be established between the entities and the names by which the entities are known. Naming is a vital issue for human cultures because names are not random sequences of characters or sounds which stand just as identifiers for the entities - they also have socio-cultural meanings and interpretations. Thus, instead of describing indivisible resources, we could describe entities that appear in a variety of names on various resources. In this study, a method is proposed to connect the names with the entities they represent and, in this way, to document the provenance of these names by connecting specific resources with specific names.

Background: Socializing the health system is a new approach to participatory governance that aims to promote community health and enhance sustainable health equity in the community. This approach is a part of health system reform in the Islamic Republic of Iran. Aims: This study aimed to develop a conceptual framework for socializing the health system in the Islamic Republic of Iran as a theoretical basis for this reform. Methods: Data were gathered through a review of the literature, in-depth interviews, focus group discussions, and panel discussions. Participants were experts in the field of health systems within the health ministry and medical universities. Content analysis was used to analyse the data and identify core values, principles, and approaches for socializing the health system. Results: The core values identified included human dignity, equity, ethics, and trust. The principles were participation, empowerment, human rights, and responsiveness. The approaches identified were good governance, a health-oriented focus, capacity-building, a process-oriented method, and improvement in the social determinants of health. A strong political will was considered essential for socializing the health system. Conclusions: The conceptual framework outlines requirements for socializing the Iranian health system. As this is a new approach in health system governance, however, it needs to be refined and redefined through implementation and evaluation.

<p><strong>Resumen</strong></p><p class="Pa8">El presente artículo pretende realizar un análisis sucinto sobre la trayectoria de la recuperación moderna del leonés, así como contribuir al campo de la sociolingüística a través de una valoración sobre las ideologías lingüísticas de las asociaciones involucradas en su protección, activas en la actualidad o en el pasado. Para ello, analizaremos las ideas y discursos que apoyan o refutan posturas hegemónicas y contrahegemónicas dentro del proceso de recuperación lingüística utilizando la teoría del sociolingüista gallego José del Valle mediante la contraposición que es­tablece entre las culturas de la monoglosia y de la heteroglosia, lo cual supone una novedad para entender el marco conceptual de la realidad lingüística leonesa dentro de esta disciplina.</p><p> </p><p><strong>Abstract</strong></p><p class="Pa8">The present article intends to elaborate on the history of the modern recovery of Leonese as well as contributing to the field of sociolinguistics through an analysis of the linguistic ideologies of the associations –cur­rently active or in the past– involved in its protection. To do so, after reviewing the style and language attitudes of the first writers in Leonese of the 20th century, we will focus on the ideas and rhetoric of associations that support or reject hegemonic or counterhegemonic stances within the process of language recovery using the theory of CUNY sociolinguist José del Valle, who establishes an opposition between the culture of monoglos­sia and the culture of heteroglossia. This new approach aims to provide a conceptual framework to understand the Leonese language situation within the field of sociolinguistics.<em> </em></p>

In this chapter, the author presents a conceptual framework for early-stage interaction design (EDOS) together with a method for embedding conceptual artifacts in user interfaces. The notion of ‘externalized design’ from postmodern architecture is used as an analogy for how to incorporate conceptual artifacts like social ideas in user interfaces. This is proposed as a new approach to theory-based design in human-computer interaction (HCI) and computer-supported collaborative learning (CSCL). The framework is applied to the retrospective analysis of two interactive systems the author has been involved in designing over a number of years. These systems were stimulated by two concepts associated with American pragmatism (generalized other, reflection-in-action). A multistage process for expressing the concepts in user interfaces is presented. The chapter ends by discussing the strengths and limitations of the EDOS framework, comparing it with related work, and suggesting directions for further work.

In recent years, Korean firms have struggled with slowdowns of both these world-first developments and their export to overseas markets. Despite technological development process, however, important questions remain with respect to how non-technological capabilities such as organizational, regulatory, and financial innovation affect accumulation and failure. To address these concerns, the key components of a conceptual framework for investigating non-technological capabilities for transition consist of the existing government, R&D organizations, and inter-firm relations. We analyze the performance and limitations of non-technological capabilities in the process of transition from the catch-up system to the innovation-based system in Korea. Using the case study of system rather than mass products, we hope that this research can contribute to the understating of non-technological features of energy-sector transitional dynamics in Korea. Finally this research would provide a new approach to the challenges from a non-technological aspect and can also provide differentiated science and technology policy strategies for the catch-up economies.
