A Note on Numerical Representations of Nested System of Strict Partial Orders

This note provides two numerical representations of a nested system of strict partial orders. The first representation is based on utility and threshold functions. We generalize the threshold representation of menu-dependent preferences by allowing the threshold to depend not only on the menu but also on the pair of alternatives under comparison. The threshold function can be interpreted as the distance between alternatives. The second representation is based on the aggregation of multi-dimensional preference. This representation describes a decision-making procedure where multiple criteria are gradually aggregated into an overall assessment.

Migration and justice in the era of sustainable development goals: a conceptual framework

Migration and mobility are major characteristics of societies worldwide. The reasons for and pathways of migrations vary, as do perceptions of migration. Political debates are often organised normatively: the debate on the sustainable development goals presents migration foremost as a development issue resulting from global inequalities. The problems faced by particular migrants, and what a more sustainable approach to migration would look like are, therefore, often lost in political debates. We aim to address those gaps: the article conceptualizes, based on established academic debates, how sustainability in migration can be addressed systematically, which aspects are important for a more sustainable migration process and which trade-offs and injustices exist from several perspectives. We create a conceptual framework of sustainability in migration processes, building on the concepts of inter- and intragenerational justice, commonly accepted as the core of the sustainability concept. We apply this conceptual framework to empirical findings on labour migration and multilocality in Kyrgyzstan. The case enables consideration of the nested system effects of scale and translocality. This research is novel because it bridges the divided literature on migration, justice and sustainability, integrates theoretical and empirical insights and provokes a debate on which kind of migration we want to achieve.

Who responds to whom and for what? A grounded theory analysis of social responsibility in the 1857 Frankfurt Bienfaisance Congress

Purpose The purpose of this study is to examine and interpret the characteristics of social responsibility in general, and business responsibility in particular, that were evident during a period in European history that was plagued by widespread social problems and change. Based on that interpretation, the authors explore the lessons those characteristics may have for social responsibility in a contemporary world that is facing similar conditions. Design/methodology/approach The paper presents a qualitative analysis of the proceedings of the Bienfaisance Congress held in Frankfurt in 1857, where societal leaders from different nations met to answer the question, who has responsibility for whom, and for what? The authors use grounded theory, as it is operationalized in what is known as the “Gioia template,” to conduct a structured analysis of this particular text, and to in turn produce a theoretical interpretation of how that question was answered. Findings The interpretation from this study is that congress participants articulated certain established dimensions of responsibility (individual, organizational, national), as well as one new dimension (international), and did so by differentiating boundaries of responsibility; in turn, the authors suggest that these dimensions and boundaries work together to form a nested system of responsibilities. Research limitations/implications There is limited empirical evidence available that documents the variety of responsibility-based initiatives that were being conducted during the 19th century. An analysis of the congress proceedings allows us to gain a better understanding of how the 19th-century world, particularly the upper echelons of European society, approached the question of under what conditions actors in different domains have responsibility for another. While the implications are limited by the analysis of the proceedings of one congress that was attended by elites, they do provide a snapshot of how Europe sought to articulate a system of bounded responsibilities during a time of widespread social problems and change. Practical implications Although the nested system of responsibilities framework that emerged from the grounded theory analysis is not applicable to all situations, it should sensitize policymakers and business leaders to the need to address social problems in a systemic way. Originality/value The authors both present a systems-based framework for understanding how responsibility is differentiated among actors (individual, organizational, state and international) and demonstrate how a theoretical interpretation of historical documents can be accomplished through the use of grounded theory, as operationalized through the Gioia template.

Nested Shallow Geothermal Systems

The long-term sustainability of shallow geothermal systems in dense urbanized areas can be potentially compromised by the existence of thermal interfaces. Thermal interferences between systems have to be avoided to prevent the loss of system performance. Nevertheless, in this work we provide evidence of a positive feedback from thermal interferences in certain controlled situations. Two real groundwater heat pump systems were investigated using real exploitation data sets to estimate the thermal energy demand bias and, by extrapolation, to assess the nature of thermal interferences between the systems. To do that, thermal interferences were modelled by means of a calibrated and validated 3D city-scale numerical model reproducing groundwater flow and heat transport. Results obtained showed a 39% (522 MWh·yr−1) energy imbalance towards cooling for one of the systems, which generated a hot thermal plume towards the downgradient and second system investigated. The nested system in the hot thermal plume only used groundwater for heating, thus establishing a positive symbiotic relationship between them. Considering the energy balance of both systems together, a reduced 9% imbalance was found, hence ensuring the long-term sustainability and renewability of the shallow geothermal resource exploited. The nested geothermal systems described illustrate the possibilities of a new management strategy in shallow geothermal energy governance.
