This paper presents the application of a Multi-Level Agent Based Model technology through a Natural Model based Design in Context (NMDC) to describe and model a class of environ-mental problems. NMDC allow training domain expert to design a conceptual model for a concrete environmental problem. This model describes the underlying application domain in terms of environmental concepts and neither requires specific technical skills nor involves implementation details. We show how the associated TiC (Tool-in-Context) develop through NMDC can help the domain expert to describe in semi-natural (specific) language the environmental problem. This description is the basis for TiC to generate a simulation tool. On the base of this, we transform the specific language to NetLogo agent based code, thereby facilitating an early prototype application to be used by the domain expert. Finally, we applied this approach to explain and analyze the process of deforestation around the Laf Forest Reserve and discuss the prototype resulting from our approach. Cet article présente une application de l’approche de modélisation multi-échelle à base d’agent en s’appuyant sur un modèle spécifique (NMDC) pour décrire et modéliser une classe de problèmes environnementaux. Le modèle NMDC permet à l’expert du domaine de décrire le domaine d’application sous-jacent en termes de concepts environnementaux et ne nécessite pas de compétences techniques spécifiques, ni de détails de mise en oeuvre. Nous montrons comment l’outil TiC (Tool-in-Context) associé développé à partir du modèle NMDC peut aider l’expert du domaine à décrire dans un langage naturel (spécifique) le problème environnemental. Cette description est la base pour l’outil TiC de générer un outil de simulation. A travers cet outil, nous transformons le langage spécifique en code multi-agents NetLogo, facilitant ainsi un premier prototype de l’application pouvant être utilisé par l’expert de domaine. Enfin, nous appliquons cette approche pour expliquer et analyser le processus de déforestation autour de la réserve forestière de Laf et discuter du prototype résultant de notre approche.

This paper proposes a conceptual implementation model for small and medium enterprises (SMEs) to follow as part of their digital transformation. The conceptual model can be translated into a practical step-by-step guide for SMEs to apply during their digital transformation. The model is based on gradually developing industrial capabilities that can influence production processes performance. We employed a comparative case study approach to capture the lessons learned by SMEs in their journey to develop and implement a production digitalization system for deviation management and performance improvement. The model was validated in the cases of study capturing the actual SMEs’ needs. Managerial capabilities of production processes such as monitoring and control demonstrate to influence the performance positively. The proposed model aims for a full digital transformation by following a gradual approach to being resource-efficient and integrating their business needs. This paper is an extension of work originally presented in APMS 2020, IFIP AICT 592.

In order to electrify the transport sector, scores of charging stations are needed to incentivize people to buy electric vehicles. In urban areas with a high charging demand and little space, decision-makers are in need of planning tools that enable them to efficiently allocate financial and organizational resources to the promotion of electromobility. As with many other city planning tasks, simulations foster successful decision-making. This article presents a novel agent-based simulation framework for urban electromobility aimed at the analysis of charging station utilization and user behavior. The approach presented here employs a novel co-evolutionary learning model for adaptive charging behavior. The simulation framework is tested and verified by means of a case study conducted in the city of Munich. The case study shows that the presented approach realistically reproduces charging behavior and spatio-temporal charger utilization.

Abstract Public-Private Innovation Partnerships (PPIPs) are increasingly used as a tool for addressing ‘wicked’ public sector challenges. ‘Innovation’ is, however, frequently treated as a ‘magic’ concept: used unreflexively, taken to be axiomatically ‘good’, and left undefined within policy programmes. Using McConnell’s framework of policy success and failure and a case study of a multi-level PPIP in the English health service (NHS Test Beds), this paper critically explores the implications of the mobilisation of innovation in PPIP policy and practice. We highlight how the interplay between levels (macro/micro and policy maker/recipient) can shape both emerging policies and their prospects for success or failure. The paper contributes to an understanding of PPIP success and failure by extending McConnell’s framework to explore inter-level effects between policy and innovation project, and demonstrating how the success of PPIP policy cannot be understood without recognising the particular political effects of ‘innovation’ on formulation and implementation.

Building on historical and discursive institutionalism, this article examines the agent-based dynamics of gradual institutional change. Specifically, using marriage equality in the United States as a case study, we examine how actors’ ideational work enabled them to make use of the political and discursive opportunities afforded by multiple venues to legitimize the process of institutional change to take off sequentially through layering, displacement, and conversion. We also pay special attention to how the discursive strategies deployed by LGBT advocates, religious-conservative organizations and other private actors created new opportunities to influence policy debates and tip the scales to their preferred policy outcome. The sequential perspective adopted in this study allows problematizing traditional conceptualizations of which actors support or contest the status quo, as enduring oppositional dynamics lead them to perform both roles in subsequent phases of the institutional change process.

Deepwater lobes constitute a significant volume of submarine fans and are primarily believed to exhibit a simple sheet geometry. However, recent studies interpret the geometries of these deep-marine lobes as distinct with respect to the complexity of the facies and their distribution. Hence, a conceptual model of deep-marine sediments is essential to discuss the deep-marine sediments associated with the fan and lobe architecture. The present study highlights the facies heterogeneity and distribution of various lobe elements at a multiscale level by considering a case study of the West Crocker Formation of Sabah in northwest Borneo. The formation was logged on a bed-to-bed scale from recently well-exposed sections, with a total vertical thickness of more than 300 m. The lithological characteristics, bed geometry, sedimentary textures and structures of individual beds were used to categorize the rock units into nine sedimentary lithofacies: five sandstone lithofacies (S1–S5), one hybrid bed facies (H), two siltstone facies (Si1 and Si2) and one shale or mudstone facies (M). These facies were grouped into four facies associations (FA1–FA4), which were interpreted as lobe axis (FA1), lobe off-axis (FA2), lobe fringe (FA3) and distal fringe to interlobe (FA4) facies associations. This study is applicable for the distribution of lobes and their subseismic, multiscale complexities to characterize the potential of hydrocarbon intervals in deep-marine sand-shale system around the globe.

Working Out

The increased authority delegated to independent agencies raises questions about the conditions of politically accountable governance, and specifically parliament’s role as a representative institution. Focusing on committee hearings as an accountability mechanism, we ask: How can a parliament employ hearings to ensure that the ends pursued by agencies have a democratic foundation? We propose a model of “mutual attunement” where accountability relations presuppose a process of working-out shared understandings of the ends, means and circumstances of policy needs. We test our argument through a case study assessing the interaction between the European Parliament’s Committee on Economic & Monetary Affairs and the European Securities and Markets Authority. Theoretically, we contribute to discussions on agency accountability and European governance, while providing a novel conceptual model and the first analysis of its kind.

Insight Into

AbstractOstia, the ancient port of Rome, had a rich religious landscape. How processional rituals further contributed to this landscape, however, has seen little consideration. This is largely due to a lack of evidence that attests to the routes taken by processional rituals. The present study aims to address existing problems in studying processions by questioning what factors motivated processional movement routes. A novel computational approach that integrates GIS, urban network analysis, and agent-based modelling is introduced. This multi-layered approach is used to question how spectators served as attractors in the creation of a processional landscape using Ostia’s Campo della Magna Mater as a case study. The analysis of these results is subsequently used to gain new insight into how a greater processional landscape was created surrounding the sanctuary of the Magna Mater.

This paper examines the way that the Italian media use language to refer to female ministers in the last three governments. While Italian is a gender-specific language (e.g., a root of the job titles can be followed by either feminine or masculine morphemes, singular and plural), it is common to use masculine forms to refer to and address women. Ministro is one of those cases where masculine forms replace feminine ones – a practice which could be construed as sexist, is only rarely challenged in institutions, and to which attention has only recently been paid in academia ( Fusco, 2012 ; and Robustelli, 2012a , 2012b ). The investigation presented here focusses on how grammar is translated in a way that reproduces women's invisibility in a sexist society. A corpus-based quantitative analysis of feminine and masculine forms of ministr– used in three widely read printed Italian newspapers (Corriere della Sera, Il Resto del Carlino and La Stampa) is undertaken. Newspaper articles were collected in the period 2012–14 to cover the Monti technocratic government (three female ministers), and left-winged Letta (seven female ministers) and part of the Renzi (seven female ministers) political governments. This paper contributes to the literature on language reform and sexist language in traditionally male-inhabited physical and metaphysical (stereotypes, prototypes) spaces such as the institutional public sphere.
