The bullwhip effect is a pervasive phenomenon in all supply chains causing excessive inventory, delivery delays, deterioration of customer service, and high costs. Some researchers have studied this phenomenon from a financial perspective by shedding light on the phenomenon of cash flow bullwhip (CFB). The objective of this article is to provide the state of the art in relation to research work on CFB. Our ambition is not to make an exhaustive list, but to synthesize the main contributions, to enable us to identify other interesting research perspectives. In this regard, certain lines of research remain insufficiently explored, such as the role that supply chain digitization could play in controlling CFB, the impact of CFB on the profitability of companies, or the impacts of the omnichannel commerce on CFB.

Residual Distribution Schemes

AbstractWe describe and review non oscillatory residual distribution schemes that are rather natural extension of high order finite volume schemes when a special emphasis is put on the structure of the computational stencil. We provide their connections with standard stabilized finite element and discontinuous Galerkin schemes, show that their are really non oscillatory. We also discuss the extension to these methods to parabolic problems. We also draw some research perspectives.

This article reviews the state-of-the-art developments in Multi-Agent Systems (MASs) and their application to energy optimization problems. This methodology and related tools have contributed to changes in various paradigms used in energy optimization. Behavior and interactions between agents are key elements that must be understood in order to model energy optimization solutions that are robust, scalable and context-aware. The concept of MAS is introduced in this paper and it is compared with traditional approaches in the development of energy optimization solutions. The different types of agent-based architectures are described, the role played by the environment is analysed and we look at how MAS recognizes the characteristics of the environment to adapt to it. Moreover, it is discussed how MAS can be used as tools that simulate the results of different actions aimed at reducing energy consumption. Then, we look at MAS as a tool that makes it easy to model and simulate certain behaviors. This modeling and simulation is easily extrapolated to the energy field, and can even evolve further within this field by using the Internet of Things (IoT) paradigm. Therefore, we can argue that MAS is a widespread approach in the field of energy optimization and that it is commonly used due to its capacity for the communication, coordination, cooperation of agents and the robustness that this methodology gives in assigning different tasks to agents. Finally, this article considers how MASs can be used for various purposes, from capturing sensor data to decision-making. We propose some research perspectives on the development of electrical optimization solutions through their development using MASs. In conclusion, we argue that researchers in the field of energy optimization should use multi-agent systems at those junctures where it is necessary to model energy efficiency solutions that involve a wide range of factors, as well as context independence that they can achieve through the addition of new agents or agent organizations, enabling the development of energy-efficient solutions for smart cities and intelligent buildings.

This chapter is dedicated to the food-heritage-education for climate emergency trinomial (FoHECE). It disseminates a study in the Euroregion of Eixo Atlântico. This Euroregion (Galicia, Spain and Northern Portugal) has been a victim of climate change (CC) due to drought. The project consisted of a participatory-action-research (PAR) with a set of environmental education facilities (EEF) that promote the connection local heritage-global reality. The main objective of the study was to help re-signifying activities in education for climate emergency based on dietary styles. Thus, a pedagogical activity was created with each facility, according to the PAR methodology, to sub-themes of the diet-CC binomial (e.g,. types of food consumed, origin, type of production, presentation) and to food aspects of each EEF surrounding. In addition to the state-of-the-art review on FoHECE, results are discussed, and recommendations are suggested for future approaches and adaptations of this methodology to other contexts.

The background of this article is the observation that the methodological discussions about qualitative research in German-speaking and Anglo-Saxon contexts are quite different. The article gives an overview of the state of the art of qualitative research in terms of its methodological development and its establishment in the broader field of social research. After some brief remarks about the history of the field, the major research perspectives and schools of qualitative research - grounded theory, ethnomethodology, narrative analysis, objective hermeneutics, life-world analysis, ethnography, cultural and gender studies - are outlined against the background of recent developments. The establishment of qualitative research is discussed with reference to the examples of the German and International Sociological Associations (DGS and ISA), to developments in the area of textbooks and handbooks, and to the founding of specialized journals. Methodological trends such as the move to visual and electronic data, triangulation of methods and the hybridization of qualitative procedures are discussed. In conclusion some perspectives are outlined which are expected to become more important in the future of qualitative research or which are seen as demands for further clarification. Beside the use of computers and further clarification on linking qualitative and quantitative research, and the limits and problems of such linkage, further suggestions concerning the ways of presenting appropriate and at the same time compulsory criteria for qualitative research are mentioned. Trends in building schools and developing research pragmatics, on the one hand, and a tendency towards elucidation and mystification of methodological procedures, on the other hand, are identified as tensional fields in methodological discussions in qualitative research. Finally a stronger internationalization in different directions and answering the question of indication are discussed as needs for the future of qualitative research.

Abstract With the growing amount and increasing heterogeneity of research on purpose-oriented networks (PONs) in the public sector, it is imperative to find a way to synthesize this research. Drawing on the varied research perspectives on PONs, we advance the idea of paradigm interplay and meta-synthesis as aspirations for the field and argue this is especially key if we want the study of PONs to inform practice. However, we recognize several challenges in the current state of the PON research that prevent the field from making strides in paradigm interplay and meta-synthesis. We discuss six challenges which we consider the most critical: different labels, differences across research foci, variation in measurement, the nestedness of networks, the dynamism of networks, and variation in the network context. We suggest six good research practices that could contribute to overcoming the challenges now so as to make integration of the research field more of a possibility in the future.

The study of stable isotopes surviving in human bone is fast becoming a standard response in the analysis of cemeteries. Reviewing the state of the art for Roman Britain, the author shows clear indications of a change in diet (for the better) following the Romanisation of Iron Age Britain—including more seafood, and more nutritional variety in the towns. While samples from the bones report an average of diet over the years leading up to an individual's death, carbon and nitrogen isotope signatures taken from the teeth may have a biographical element—capturing those childhood dinners. In this way migrants have been detected—as in the likely presence of Africans in Roman York. While not unexpected, these results show the increasing power of stable isotopes to comment on populations subject to demographic pressures of every kind.
