Bhaskar and Bunge on Social Emergence

2009

This article discusses the theories of social emergence developed by Roy Bhaskar and Mario Bunge. Bhaskar's concept of emergent causal power is shown to be ambiguous, and some of the difficulties of his depth-relational concept of social emergence are examined. It is argued that Bunge's systemic concept of emergent property is not only different, but also clearer and more consistent than Bhaskar's concept of emergent causal power. Despite its clarity and consistency, Bunge's definition of the concept of emergent property is shown to be too broad and analytically imprecise for the purposes of an emergentist social ontology. It is argued that Bunge's systemic account of social emergence can b…

Mobile Mapping System: case study of the Messina-Palermo motorway layout

2009

This paper presents the first results of the MMS (Mobile Mapping System) survey on the geometry of the A20 italian motorway Messina-Palermo. The layout parameters are the essential data for an effective management of a single or a road network. In particular these parameters are essential for applying the Design Consistency methodology to proposed or existing road infrastructures; through this methodology the road manager can make sure that the road characteristics are adjusted to the driving behaviour of motorists by analysing the relationship between horizontal and vertical alignment and the design and operating speed. Both the difficult finding of the road design schemes, particularly in…

Inconsistency measuring over multisets of formulas

2018

International audience; Measuring Inconsistency in Information : The concept of measuring inconsistency in information was developed by John Grant in a 1978 paper in the context of first-order logic. For more than 20 years very little was done in this area until in the early 2000s a number of AI researchers started to formulate new inconsistency measures primarily in the context of propositional logic knowledge bases. The aim of this volume is to survey what has been done so far, to expand inconsistency measurement to other formalisms, to connect it with related topics, and to provide ideas for further research in a topic that is particularly relevant now in view of the many inconsistencies…

Structure and function of the vacuolar Ccc1/VIT1 family of iron transporters and its regulation in fungi

2020

Iron is an essential micronutrient for most living beings since it participates as a redox active cofactor in many biological processes including cellular respiration, lipid biosynthesis, DNA replication and repair, and ribosome biogenesis and recycling. However, when present in excess, iron can participate in Fenton reactions and generate reactive oxygen species that damage cells at the level of proteins, lipids and nucleic acids. Organisms have developed different molecular strategies to protect themselves against the harmful effects of high concentrations of iron. In the case of fungi and plants, detoxification mainly occurs by importing cytosolic iron into the vacuole through the Ccc1/V…

The Reprocessed Proba-V Collection 2: Product Validation

2021

With the objective to improve data quality in terms of cloud detection, absolute radiometric calibration and atmospheric correction, the PRoject for On-Board Autonomy-Vegetation (PROBA-V) data archive (October 2013 - June 2020) will be reprocessed to Collection 2 (C2). The product validation is organized in three phases and focuses on the intercomparison with PROBA-V Collection 1 (C1), but also consistency analysis with SPOT-VGT, Sentinel-3 SYN-VGT, Terra-MODIS and METOP-AVHRR is foreseen. First preliminary results show the better performance of cloud and snow/ice masking, and indicate that statistical consistency between PROBA-V C2 and C1 are in line with expectations. PROBA-V C2 data are …

Robust Neural Machine Translation: Modeling Orthographic and Interpunctual Variation

2020

Neural machine translation systems typically are trained on curated corpora and break when faced with non-standard orthography or punctuation. Resilience to spelling mistakes and typos, however, is crucial as machine translation systems are used to translate texts of informal origins, such as chat conversations, social media posts and web pages. We propose a simple generative noise model to generate adversarial examples of ten different types. We use these to augment machine translation systems’ training data and show that, when tested on noisy data, systems trained using adversarial examples perform almost as well as when translating clean data, while baseline systems’ performance drops by…

Counting by Statistics on Search Trees: Application to Constraint Satisfaction Problems

1997

In 1975, Knuth proposed a simple statistical method for investigating search trees. We use this technique for estimating the number of solutions of constraint satisfaction problem CSP and boolean satisfiability problem SAT instances. We show that, depending on domain reductions, tree-based estimates have a lower variance than estimates based on uniform sampling from the search space. Nevertheless, because the variance remains extremely high in the general case, a confidence interval cannot be derived, but a lower bound of the number of solutions. These results are confirmed by many experiments.

Consistencies of psychomotor styles in interpersonal tasks

1975

Abstract.— Interpersonal behaviour of individuals in five tasks (individual performance, two dyadic tasks, two small-group tasks) was videotaped and coded on 11 psychomotor categories concerning (a) movements regulating interaction, (b) indications of tension, and (c) temperamental acts. The individual consistencies were examined on the basis of correlational analyses and task similarities. The consistency of individual psychomotor behaviour across all the tasks was highest in the number of selfinitiated acts (psychomotor activeness). Consistency was also found in the total tension score and the utilization of large/narrow space, while the effect of the particular tasks was clearly demonstr…

ProcMiner: Advancing Process Analysis and Management

2007

This paper contributes both to research and practice on process mining. Previous research on process mining has focused on mining patterns from event log files to generate process models. The process mining approach adopted in this paper is focused on producing patterns about process models, not the models themselves. The approach is demonstrated by ProcMiner -an explorative research prototype for management, consolidating, publishing, retrieving, and analyzing process models. Content-based document clustering is applied to process models represented as XML database in order to find topical groups from models. In practice, organizations face numerous challenges in managing their process mod…
