Interpretation, Truth and Correspondence

2000

The correspondence theory of truth is usually considered unsuitable for qualitative research. This is because of the interpretive nature of social reality and subjective nature of research procedures. Contra these ideas it is argued that the correspondence theory of truth is presupposed in the practice of qualitative research. This theory does not, however, dictate any methods for verifying the interpretations. Various theories of truth are seen as necessary because of the complexity of the interpretation process.

Automatic orientation and 3D modelling from markerless rock art imagery

2013

This paper investigates the use of two detectors and descriptors on image pyramids for automatic image orientation and generation of 3D models. The detectors and descriptors replace manual measurements and are used to detect, extract and match features across multiple imagery. The Scale-Invariant Feature Transform (SIFT) and the Speeded Up Robust Features (SURF) will be assessed based on speed, number of features, matched features, and precision in image and object space depending on the adopted hierarchical matching scheme. The influence of applying in addition Area Based Matching (ABM) with normalised cross-correlation (NCC) and least squares matching (LSM) is also investigated. The pipel…

Terrorismo e Mafia

2020

The issue of «Meridiana» analyses counter-terrorism and mafia strategies over the course of Italian history from a double viewpoint (both legal and historical). The contributions of the different authors follow the evolution of criminal, substantive and procedural rules while identifying a unitary, «emerging» trait. Exceptionality, which has become one of the permanent characteristics of the Italian criminal justice system. The studies of some famous cases highlights the twists of the legal categories, the use of repentants, and the close collaboration between the judges and the public prosecutors. Risky interference between historiography and procedure requires that the criminal dimension …

Truth and Historicism in Kuhn’s Thesis of Methodological Incommensurability

2013

Methodological incommensurability is a Thomas Kuhn’s thesis affirming that there are not shared, objective methodological rules or neutral scientific standards for theory comparison and choice. This thesis has often been interpreted as a relativistic and irrationalist claim on the incomparability of scientific theories. Since every paradigm refers to its standards, problem-field and aims, theory choice is subjective and arbitrary. Moreover it seems that, in his latest works, Kuhn abandons this aspect of incommensurability to focus on semantic incommensurability. On the contrary I will argue against the interpretation of methodological incommensurability as a source of epistemological relati…

2021

Two centuries later, the legend Chopin-Sand continues to supply the collective imaginary with vague readings, where historical truthfulness, let alone musical truth, is often contingent on the literary. The much discussed and bellicose romance between the Polish composer and the French novelist, George Sand, tends to some reductionism and evades an obvious reality: Fryderyk Chopin meets George Sand when she was already the mother of two children. This circumstance suggests reformulating certain romantic stereotypes. Jerzy Antczak?s biographical film Pragnienie Mi?o?ci (Chopin: Desire for Love, 2002) does not overlook this detail and makes it one of its narrative axes. The relationship betwe…

Oblio, identità e verità (parte seconda)

2022

Può esistere un diritto a dimenticare a fronte di indiscutibile diritto a ricordare, senza che si consegni alle Corti il potere di riscrivere la storia eliminando frammenti della sua memoria? È attorno tale interrogativo che si snodano le riflessioni dell’autore, dirette ad accertare l’esistenza e la natura di un diritto all’oblio, inteso come diritto ad essere dimenticati. La rivoluzione digitale ha consentito la creazione di un archivio infinito e permanente, ma legittimo appare il dubbio circa l’opportunità di un suo indiscriminato sviluppo e di una illimitata tutela del diritto alla memoria, a fronte di istanze di tutela individuale di dignità umana. La risposta, secondo l’autore, è nel…

Assessment of vine development according to available water resources by using remote sensing in La Mancha, Spain

1999

Abstract The relevance of growing vines under semiarid conditions is universally accepted because of its impacts on social, economic and environmental aspects. Improving the knowledge of the soil–plant–atmosphere system related to the expression of vine growth allows the study of vine cover in wide areas. Several aspects of vine growing under semiarid conditions, related to weather, soil, and plant cover are analysed in this paper. Once the ground truth is achieved, multitemporal studies by remote sensing are especially useful for vine growth monitoring. The purpose of this work is focussed on determining changes of vine cover development according to available water resources in relation t…

Overlapping community detection versus ground-truth in AMAZON co-purchasing network

2015

International audience; Objective evaluation of community detection algorithms is a strategic issue. Indeed, we need to verify that the communities identified are actually the good ones. Moreover, it is necessary to compare results between two distinct algorithms to determine which is most effective. Classically, validations rely on clustering comparison measures or on quality metrics. Although, various traditional performance measures are used extensively. It appears very clearly that they cannot distinguish community structures with different topological properties. It is therefore necessary to propose an alternative methodology more sensitive to the community structure variations in orde…

Performance Measurement of Mobile Manipulators

2015

International audience; This paper describes a concept for measuring the reproducible performance of mobile manipulators to be used for assembly or other similar tasks. An automatic guided vehicle with an onboard robot arm was programmed to repeatedly move to and stop at a novel, reconfigurable mobile manipulator artifact (RMMA), sense the RMMA, and detect targets on the RMMA. The manipulator moved a laser retroreflective sensor to detect small reflectors that can be reconfigured to measure various manipulator positions and orientations (poses). This paper describes calibration of a multi-camera,motion capture system using a 6 degree-of-freedom metrology bar and then using the camera system…
