A DISCOURSE ANALYSIS APPROACH TO EXPLAIN THE PATH DEPENDENCY OF SEASONAL FARM LABOUR REGULATIONS IN GERMANY

This article introduces discourse analysis as a theoretical concept and an empirical methodology that may enable the endogenization of path creation and path breaking changes in conventional models of political path dependencies. Economic criteria such as rents created by a policy do not always provide a comprehensive explanation for path dependent political decisions. Discourse theory implies that specific interpretative schemata and narratives, such as storylines in the mass media, heavily influence the political discourse. Discourses themselves exercise a constitutive power that constrains decision-making processes and, thus, influence the ensuing policy creation path. Hence, discourses must be taken into account when political path creation is analysed. In this paper we trace over time individual storylines that represent important elements of the discourse underlying the restriction of seasonal farm workers from central and eastern European countries in Germany. We illustrate how dominant speakers and their storylines have been and currently are interacting to shape this policy.Agricultural Policy, Path Dependencies, Discourse Analysis, Seasonal Farm Labour, Institutional and Behavioral Economics,

Storyline description of Southern Hemisphere midlatitude circulation and precipitation response to greenhouse gas forcing

As evidence of climate change strengthens, knowledge of its regional implications becomes an urgent need for decision making. Current understanding of regional precipitation changes is substantially limited by our understanding of the atmospheric circulation response to climate change, which to a high degree remains uncertain. This uncertainty is reflected in the wide spread in atmospheric circulation changes projected in multimodel ensembles, which cannot be directly interpreted in a probabilistic sense. The uncertainty can instead be represented by studying a discrete set of physically plausible storylines of atmospheric circulation changes. By mining CMIP5 model output, here we take this broader perspective and develop storylines for Southern Hemisphere (SH) midlatitude circulation changes, conditioned on the degree of global-mean warming, based on the climate responses of two remote drivers: the enhanced warming of the tropical upper troposphere and the strengthening of the stratospheric polar vortex. For the three continental domains in the SH, we analyse the precipitation changes under each storyline. To allow comparison with previous studies, we also link both circulation and precipitation changes with those of the Southern Annular Mode. Our results show that the response to tropical warming leads to a strengthening of the midlatitude westerly winds, whilst the response to a delayed breakdown (for DJF) or strengthening (for JJA) of the stratospheric vortex leads to a poleward shift of the westerly winds and the storm tracks. However, the circulation response is not zonally symmetric and the regional precipitation storylines for South America, South Africa, South Australia and New Zealand exhibit quite specific dependencies on the two remote drivers, which are not well represented by changes in the Southern Annular Mode

Pan-European backcasting exercise, enriched with regional perspective, and including a list of short-term policy options

This deliverable reports on the results of the third and final pan-European stakeholder meeting and secondly, on the enrichment with a Pilot Area and regional perspective. The main emphasis is on backcasting as a means to arrive at long-term strategies and short-term (policy) actions

If telecare is the answer, what was the question? Storyline, tensions and the unintended consequences of technology-supported care

The relationship between policies about telecare and the experiences and aspirations of service users has been under-interrogated. This paper draws on findings from an organisational case study involving people living with complex conditions using various telecare devices and employs Hajer’s (1995) concept of argumentative discourse analysis to identify two key storylines arguing that telecare improves people’s quality of life and promotes independence. While these storylines point to seemingly logical and incontestable objectives, uncritical policy and practice fails to recognise and prioritise the aspirations of service users, leading to unintended consequences that can deepen people’s isolation and minimise organisational benefits.Peer reviewedFinal Accepted Versio

Multimodal Storytelling via Generative Adversarial Imitation Learning

Deriving event storylines is an effective summarization method to succinctly organize extensive information, which can significantly alleviate the pain of information overload. The critical challenge is the lack of widely recognized definition of storyline metric. Prior studies have developed various approaches based on different assumptions about users' interests. These works can extract interesting patterns, but their assumptions do not guarantee that the derived patterns will match users' preference. On the other hand, their exclusiveness of single modality source misses cross-modality information. This paper proposes a method, multimodal imitation learning via generative adversarial networks(MIL-GAN), to directly model users' interests as reflected by various data. In particular, the proposed model addresses the critical challenge by imitating users' demonstrated storylines. Our proposed model is designed to learn the reward patterns given user-provided storylines and then applies the learned policy to unseen data. The proposed approach is demonstrated to be capable of acquiring the user's implicit intent and outperforming competing methods by a substantial margin with a user study.Comment: IJCAI 201

Scenarios for land use and food security at global, regional and national scales. [ID812]

Researchers from Cirad and Inra, with the support of a Scenario Advisory Committee, have carried out an exploratory foresight exercise on 'Land use and food security in 2050' (Agrimonde-Terra) to prepare actors for different possible futures by providing them with elements for understanding and anticipating future issues. The method combines various approaches: a scenario method based on morphological analysis and applied at various system scales, the implementation of foresight forums to discuss hypotheses on evolutions of the system and the construction and use of a modelling and simulation tool, called GlobAgri-AgT. The land use system was broken down into sub-systems or external and direct drivers for which alternative hypotheses of changes to 2050 were constructed; then hypotheses were combined in plausible and internally consistent ways and gave shape to different traceable scenarios. At the global level, Agrimonde-Terra proposes a trend analysis on the global context, climate change, food diets, urban-rural linkages, farm structures, cropping and livestock systems, and explores five scenarios. Three scenarios entitled 'Metropolization', 'Regionalization' and 'Households' are based on current competing trends identified in most world regions. Two scenarios entitled 'Healthy' and 'Communities' involve potential breaks that could change the entire land use and food security system. For six regions of the world (OECD, FSU, Latin America, North Africa, SSA and Asia), past and on-going trends towards each scenario have been identified. The method has been used at the national level, in Tunisia. During several foresight fora, stakeholders and decision-makers of the agri-food system designed their own "land use and food security system", defined their hypotheses for each driver, built scenarios with these assumptions, compared scenarios using a number of criteria and discussed consequences for policy-making. GlobAgri-AgT can be used for quantifying the consequences of scenarios on areas and trade

On Minimizing Crossings in Storyline Visualizations

In a storyline visualization, we visualize a collection of interacting characters (e.g., in a movie, play, etc.) by $x$-monotone curves that converge for each interaction, and diverge otherwise. Given a storyline with $n$ characters, we show tight lower and upper bounds on the number of crossings required in any storyline visualization for a restricted case. In particular, we show that if (1) each meeting consists of exactly two characters and (2) the meetings can be modeled as a tree, then we can always find a storyline visualization with $O(n\log n)$ crossings. Furthermore, we show that there exist storylines in this restricted case that require $\Omega(n\log n)$ crossings. Lastly, we show that, in the general case, minimizing the number of crossings in a storyline visualization is fixed-parameter tractable, when parameterized on the number of characters $k$. Our algorithm runs in time $O(k!^2k\log k + k!^2m)$, where $m$ is the number of meetings.Comment: 6 pages, 4 figures.

Making sense of tragedy: the ‘reputational’ antecedents of a hospital disaster

This article explores the workings of Reputational Dialogues (RD) (as a form of organizational discourse); within the setting of a UK NHS hospital that has encountered disaster. The disaster in question took place at the Bristol Royal Infirmary (BRI), circa 1984-1995; and is thought to have incurred the deaths of 34 ‘special heart babies’. The article explores patterns of RD utilization associated with the tragedy. Transcripts from the hearings of an inquiry into the disaster are used to access these patterns– if within specific limits and constraints that are discussed in the article. The article seeks to comment on the workings of RDs within the BRI disaster setting and considers, tentatively, how these dialogues may have helped to institutionalize dominant and (counter-cultural beliefs) about the BRI and its reputation as a provider of cardiovascular care to young children. Overall, the article contributes to organization theory by beginning the process of observing the institutionalization of RD and its by-products, as organizational phenomena
