description: Satellite observations of the geomagnetic field contain signals generated in Earth's interior by electrical currents in the core and by magnetized rocks in the lithosphere. At short wavelengths the lithospheric signal dominates, obscuring the signal from the core. Here we present details of a method to co-estimate separate models for the core and lithospheric fields, which are allowed to overlap in spherical harmonic degree, that makes use of prior information to aid the separation. Using a maximum entropy method we estimate probabilistic models for the time-dependent core field and the static lithospheric field that satisfy constraints provided by satellite observations while being consistent with prior knowledge of the spatial covariance and expected magnitude of each field at its source surface.

description: This study raises the question of how the Canadian educational system can avoid promoting cultural or ideological racism in a student population that is increasingly Indigenous and immigrant. It responds to this question by pointing to the need to expand knowledge systems in teacher education programs, presenting a multi-thematic discussion that explores how contemporary ways of teaching and learning can be transformed into a diverse, sustainable, and global curriculum. The focus of the article is on school culture, specifically the Aboriginal way of knowing about language-learning, creating multicultural teachers, leadership for a culture of inclusion and diversity, and the idea of resistance to change.

description: The hydropower production, water supply and aquaculture services of the Itaparica Reservoir are of immense importance for the Brazilian Northeast. Uncontrolled water resources consumption (e.g. irrigation, water supply), climate and land use change effects deteriorated the water quantity and quality in the reservoir, leading to socio-economic and environmental problems. In this work, a depth-averaged shallow water model was set up for the Icó-Mandantes Bay, one major branch of the reservoir, using the open TELEMAC-MASCARET system. The aim was to assess the impacts of the newly built water diversion channel, as well as the effects of a flood and tracer transport from an intermittent tributary, both located in the bay. An alternative approach to estimate the water retention times was additionally implemented. The simulations showed that though the diversion channel did not significantly influence the hydrodynamics of the bay, it is necessary to continuously monitor water quality parameters in the withdrawal, especially during rainy periods after droughts, because of the nutrient inputs from the tributary and the overflows of the nearby drainage systems. Management measures adapting to the continuously changing natural conditions and anthropogenic impacts are thus indispensable and the model presented can be a valuable supporting tool for this purpose.
Cultural Mirrors Made of Papier Mâché: Challenging Misrepresentations of Indigenous Knowledges in Education Through Media
Creators: name: Iseke, Judy
Publisher: name: Alberta Journal of Educational Research
Year: 2010

description: Misrepresentation, appropriation, and denigrating Indigenous knowledge is still common practice in educational institutions despite efforts of critical educators to challenge these practices. One such challenge was to papier mâché totem poles in an education institution’s library in a faculty of education that houses teacher education programs. A papier mâché cross focused attention on the use and misuse of symbols and educated people about the problematic representational practices of papier mâché totem poles and crosses. What are the cultural discourses that support the inclusion of false representations of Indigenous knowledge in an education library? I draw attention to strategies and practices of challenging misrepresentation through the use of Indigenous media in education, examine challenges in changing institutional climates of teacher education, and encourage discussion of how Indigenous knowledge and people can be full partners in educational institutions.

False truths : misused reductionist handles examined through Canadian literature
Creators: name: Sun, Kevin
Publisher: name: University of British Columbia
Year: 2019

description: In Eurocentric culture, misused reductionist handles are manifestations of reductionism’s mutation from a specialized tool to examine limited aspects of the world into a worldview of its own, a fragmented epistemology “predicated on the discovery of a true world of realities lying behind a veil of appearances” (Latour 474-475). As someone whose naïve belief in the Eurocentric concept of Truth was challenged by exposure to Indigenous ways of knowing, I examine in this thesis the consequences of this misuse of reductionist handles by contrasting Eurocentric Canadian with Indigenous Canadian literature. In “Royal Beatings,” Alice Munro depicts how theatricality, a reductionist handle, is internalized by characters who thereby reduce themselves to culturally created roles; in “Miles City, Montana,” she depicts how idealism, another reductionist handle, is internalized by characters who then face irreconcilable contradictions in reality. On the other hand, the Nuu-chah-nulth origin story “How Son of Raven Captured the Day,” presented in E. Richard Atleo’s Tsawalk, uses theatricality as a holistic rather than reductionist tool that emphasizes the importance of maintaining respect for all. Thomas King’s Green Grass, Running Water also portrays the conflict between Eurocentric and Indigenous epistemologies through its emphasis on contextualization and use of water as a powerful holistic symbol, thus clarifying water’s rebellion against reductionism in “Miles City, Montana.” The concept of misused reductionist handles is useful for future research on reductionism’s epistemological influence, which can be guided by examining not only the differences between the Eurocentric worldview and other worldviews, but their intersections as well.

Waponahki Intellectual Tradition of Weaving Educational Policy
Creators: name: Cardinal Sockbeson, Rebecca
Publisher: name: Alberta Journal of Educational Research
Year: 2010

description: This article describes an articulation of a Waponahki intellectual tradition from the experience of a Waponahki woman attempting to position Indigenous knowledge systems in the academy. The author shows how the Waponahki intellectual tradition of weaving baskets can serve as a theoretical framework and foundation for understanding Waponahki policymaking and research. The article reports on a new law implemented in 2004 in the State of Maine that mandates the teaching of Waponahki history and culture in kindergarten through grade 12 and how teacher education programs are being developed to prepare teachers to comply with the legislation. The vision of policy direction resides in the minds of the policymaker and the community for which and with which he or she works. Like policy development, the blueprints of design for the basketry are constructed in the mind of the basketmaker; both work toward the future and continued survival of the Waponahki people. Policy development and basketmaking are more than writing texts or weaving strips of wood: both rely heavily on experience, connection to the people, and knowledge of who we are. Our basketry is intrinsic to our culture, rooted in our creation story; similarly, our policy development is critical to our decolonization and survival. The article calls for Indigenous peoples to revitalize, preserve, recognize, or even uncover their own Indigenous intellectual traditions with the vision of expanding knowledge systems.

description: The task of determining the physical coordinates of a target in indoor environments is still a key factor for many applications including people and robot navigation, user tracking, location-based advertising, augmented reality, gaming, emergency response or ambient assisted living environments. Among the different possibilities for indoor positioning, Acoustic Local Positioning Systems (ALPS) have the potential for centimeter level positioning accuracy with coverage distances up to tens of meters. In addition, acoustic transducers are small, low cost and reliable thanks to the room constrained propagation of these mechanical waves. Waveform design (coding and modulation) is usually incorporated into these systems to facilitate the detection of the transmitted signals at the receiver. The aperiodic correlation properties of the emitted signals have a large impact on how the ALPS cope with common impairment factors such as multipath propagation, multiple access interference, Doppler shifting, near-far effect or ambient noise. This work analyzes three of the most promising families of codes found in the literature for ALPS: Kasami codes, Zadoff-Chu and Orthogonal Chirp signals. The performance of these codes is evaluated in terms of time of arrival accuracy and characterized by means of model simulation under realistic conditions and by means of experimental tests in controlled environments. The results derived from this study can be of interest for other applications based on spreading sequences, such as underwater acoustic systems, ultrasonic imaging or even Code Division Multiple Access (CDMA) communications systems.

description: Orbital Kondo effect in a system of two single-level quantum dots attached to external electron reservoirs is considered theoretically. The dots are coupled via direct hoping term and Coulomb interaction. The Kondo temperature is evaluated from the scaling approach and slave boson technique. The later method is also used to calculate linear conductance of the system. Nonlinear conductance, in turn, is calculated in terms of the nonequilibrium Green function formalism.

description: While dissipative Rydberg gases exhibit unique possibilities to tune dissipation and interaction properties, very little is known about the quantum many-body physics of such long-range interacting open quantum systems. We theoretically analyze the steady state of a van der Waals interacting Rydberg gas in an optical lattice based on a variational treatment that also includes long-range correlations necessary to describe the physics of the Rydberg blockade, i.e., the inhibition of neighboring Rydberg excitations by strong interactions. In contrast to the ground state phase diagram, we find that the steady state undergoes a single first order phase transition from a blockaded Rydberg gas to a facilitation phase where the blockade is lifted. The first order line terminates in a critical point when including sufficiently strong dephasing, enabling a highly promising route to study dissipative criticality in these systems. In some regimes, we also find good quantitative agreement with effective short-range models despite the presence of the Rydberg blockade, justifying the wide use of such phenomenological descriptions in the literature.
Landau-Ginzburg-Devonshire theory for electromechanical hysteresis loop formation in piezoresponse force microscopy of thin films

description: Electromechanical hysteresis loop formation in piezoresponse force microscopy of thin ferroelectric films is studied with special emphasis on the effects of tip size and film thickness, as well as dependence on the tip voltage frequency. Here, we use a combination of Landau-Ginzburg-Devonshire (LGD) theory for the description of the local polarization reversal with decoupling approximation for the calculation of the local piezoresponse loops shape, coercive voltages and amplitude. LGD approach enables addressing both thermodynamics and kinetics of hysteresis loop formation. In contrast to the "rigid" ferroelectric approximation, this approach allows for the piezoelectric tensor components dependence on the ferroelectric polarization and dielectric permittivity. This model rationalizes the non-classical shape of the dynamic piezoelectric force microscopy (PFM) loops.

description: We offer new illumination patterns for imaging in all-digital ghost imaging (GI) systems. The digital patterns, written as computer generated holograms on spatial light modulators (SLM), are generated by the Ising model, a well-known ferromagnetic model. In general, Ising patterns are affected by the system temperature and magnetic field. For a modest number of measurements in GI, our simulations suggest that low-temperature Ising patterns outperform random patterns. We also experimentally confirm that Ising masks can be used in quantum GI. Moreover, we present a strategy for applying Ising patterns of different temperatures to obtain high-quality images with the number of measurements approximately equal to the number of pixels in the image.
Nei Quaderni filosofici di Lenin: lo studio della Logica e la lettura del proprio tempo

description: In the 50s and 60s of the twentieth century, Lucio Colletti developed a requisition against Hegel and against those elements of his philosophy that had penetrated into Marxism. The main thesis is simple and clear: the more Marxism is contaminated with Hegelism the more it loses scientific consistency. This thesis ends up investing the judgment on the work of Lenin too. The essay in question will show the opposite: the concepts that the Russian revolutionary will find in Hegel’s Logic provide him the tools usefull to avoid the ideological deviations of his time and to identify the theoretical errors committed by Trotsky and the exponents of the Second International, both prisoners of the abstract intellect and of mechanistic ways of thinking. This judgment also belonged to Gramsci, who was not by chance a reader and a profound admirer of Hegel. Both Gramsci and Lenin often accuse Trotsky and the Second Internationalists of not having been able to internalize the dialectical logic, with very serious and dangerous political repercussions.

description: This article disputes the prevailing thesis according to which the Soviet revolution represented an irreparable rift in the Western cultural tradition and even a form of destruction of universal culture. The revolution of the Bolsheviks was inspired on the theoretical level by the dialectical method elaborated by classical German philosophy and by Marxism, which constituted the historical continuation of that philosophy. Despite the great contradictions that accompanied it, and which can be explained by the very severe political struggles on the internal and the international level with which it was forced to measure itself, the era of revolution was characterized by a great flowering of political rights, economic and social and inspired a broad cultural renewal movement that has influenced historical processes even beyond Soviet Russia.

description: Compared with the rapid development of single-frequency multi-polarization SAR image classification technology, there is less research on the land cover classification of multifrequency polarimetric SAR (MF-PolSAR) images. In addition, the current deep learning methods for MF-PolSAR classification are mainly based on convolutional neural networks (CNNs), only local spatiality is considered but the nonlocal relationship is ignored. Therefore, based on semantic interaction and nonlocal topological structure, this paper proposes the MF semantics and topology fusion network (MF-STFnet) to improve MF-PolSAR classification performance. In MF-STFnet, two kinds of classification are implemented for each band, semantic information-based (SIC) and topological property-based (TPC). They work collaboratively during MF-STFnet training, which can not only fully leverage the complementarity of bands, but also combine local and nonlocal spatial information to improve the discrimination between different categories. For SIC, the designed crossband interactive feature extraction module (CIFEM) is embedded to explicitly model the deep semantic correlation among bands, thereby leveraging the complementarity of bands to make ground objects more separable. For TPC, the graph sample and aggregate network (GraphSAGE) is employed to dynamically capture the representation of nonlocal topological relations between land cover categories. In this way, the robustness of classification can be further improved by combining nonlocal spatial information. Finally, an adaptive weighting fusion (AWF) strategy is proposed to merge inference from different bands, so as to make the MF joint classification decisions of SIC and TPC. The comparative experiments show that MF-STFnet can achieve more competitive classification performance than some state-of-the-art methods.
Eric Weil: la storia come problema filosofico

description: The aim of my contribution is to show how Eric Weil (1904-1977) tried to re-propose a systematic thought capable of problematizing the relationship between history and philosophy, reality and discourse, particularity and universality. In the first part I’ll analyze the essential structure of Weil's most significant work, the Logique de la philosophie; in the second one, I’ll present the essential contents of De l’intérêt que l’on prend a l’histoire – a text where was already problematized the relationship between the universality of the historical-philosophical discourse and concrete particularity. Finally in the third and last part through analyzing Valeur et dignité du récit historiographique, we will see how Weil gave essential importance to the positive function of historical narratives, inexhaustible sources of  meaningful images for the philosopical discourse.

A fundamental relation between mass, SFR and metallicity in local and high redshift galaxies

description: We show that the mass-metallicity relation observed in the local universe is due to a more general relation between stellar mass M*, gas-phase metallicity and SFR. Local galaxies define a tight surface in this 3D space, the Fundamental Metallicity Relation (FMR), with a small residual dispersion of ~0.05 dex in metallicity, i.e, ~12%. At low stellar mass, metallicity decreases sharply with increasing SFR, while at high stellar mass, metallicity does not depend on SFR. High redshift galaxies, up to z~2.5 are found to follow the same FMR defined by local SDSS galaxies, with no indication of evolution. The evolution of the mass-metallicity relation observed up to z=2.5 is due to the fact that galaxies with progressively higher SFRs, and therefore lower metallicities, are selected at increasing redshifts, sampling different parts of the same FMR. By introducing the new quantity mu_alpha=log(M*)-alpha log(SFR), with alpha=0.32, we define a projection of the FMR that minimizes the metallicity scatter of local galaxies. The same quantity also cancels out any redshift evolution up to z~2.5, i.e, all galaxies have the same range of values of mu_0.32. At z>2.5, evolution of about 0.6 dex off the FMR is observed, with high-redshift galaxies showing lower metallicities. The existence of the FMR can be explained by the interplay of infall of pristine gas and outflow of enriched material. The former effect is responsible for the dependence of metallicity with SFR and is the dominant effect at high-redshift, while the latter introduces the dependence on stellar mass and dominates at low redshift. The combination of these two effects, together with the Schmidt-Kennicutt law, explains the shape of the FMR and the role of mu_0.32. The small metallicity scatter around the FMR supports the smooth infall scenario of gas accretion in the local universe.

description: We construct a chaotic inflation model in which the Higgs fields play the role of the inflaton in the standard model as well as in the singlet extension of the supersymmetric standard model. The key idea is to allow a non-canonical kinetic term for the Higgs field. The model is a realization of the recently proposed running kinetic inflation, in which the coefficient of the kinetic term grows as the inflaton field. The inflaton potential depends on the structure of the Higgs kinetic term. For instance, the inflaton potential is proportional to phi^2 and phi^{2/3} in the standard model and NMSSM, respectively. It is also possible to have a flatter inflaton potential.

description: We demonstrate condensate formation in a dark state in an ultracold quantum gas coupled to a high-finesse cavity and pumped by a shaken optical lattice. We show experimentally and theoretically that the atoms in the dark state display a strong suppression of the coupling to the cavity. On the theory side, this is supported by solving the dynamics of a minimal three-level model and of the full atom-cavity system. The symmetry of the condensate wave function is anti-symmetric with respect to the potential minima of the pump lattice, and displays a staggered sign along the cavity direction. This symmetry decouples the dark state from the cavity, and is preserved when the pump intensity is switched off.

description: The coupled-channels technique is applied to analyze recent fusion data for $^{48}$Ca+$^{48}$Ca. The calculations include the excitations of the low-lying $2^+$, $3^-$ and $5^-$ states in projectile and target, and the influence of mutual excitations as well as the two-phonon quadrupole excitations is also investigated. The ion-ion potential is obtained by double-folding the nuclear densities of the reacting nuclei with the M3Y+repulsion effective interaction but a standard Woods-Saxon potential is also applied. The data exhibit a strong hindrance at low energy compared to calculations that are based on a standard Woods-Saxon potential but they can be reproduced quite well by applying the M3Y+repulsion potential with an adjusted radius of the nuclear density. The influence of the polarization of high-lying states on the extracted radius is discussed.

Publisher: name: Materialismo Storico
Year: 2018

description: In this interview, André Tosel recalls the most important phases of his scientific commitment. He focuses on the different aspects of his theoretical experiences: the left-wing Catholicism, his meeting with Althusser (who shows him the analytical path from Spinoza to Marx), his discovery of Gramsci’s role in the Marxist historicism. Tosel emphasizes the differences between Althusser and Gramsci, recognizing the Italian Marxist – an author not sufficiently studied in France – as a point of reference for the elaboration of a critical analysis of the structure of the contemporary capitalism. Of course, according to Tosel, such an appreciation of Gramsci’s work does not exclude critical evaluations of his contribution.

description: This article presents the preliminary findings of a pilot study of the practice, uses, and effectiveness of traditional medicine in Ghana. Based on in-depth interviews with local key practitioners and users of traditional medicine, the article points to some of the educational significance of local cultural knowledge on the environment and the relevance of such knowledge for science education in Ghana. In the discussion the authors briefly highlight general themes relating to local understandings of traditional medicine, the distinctions between traditional and plant medicine, contestations between traditional medicine and orthodox medicine, local conceptions of health and a healthy individual, the economics of health, and the lessons of science and public education. Although the findings of the study are preliminary, the article argues that much is to be gained for educational purposes through the critical study of traditional medicine, particularly in terms of the promotion of science and community education in Ghana.

Self-assembled monolayers of biphenyls are cross-linked by electrons, detached from the surfaces and subsequently pyrolized. Above 1000K, the cross-linked aromatic monolayer forms a mechanically stable graphitic phase. The transition is accompanied by a drop of the sheet resistivity from ~10^8 to ~10^2 kOhm/sq and a mechanical stiffening of the nanomembranes from ~10 to ~50 GPa. The technical applicability of the nanosheets is demonstrated by incorporating them into a microscopic pressure sensor

description: We propose simple scenarios where lepton flavor-violating couplings generate the observed dark matter abundance through freeze-in of an axion-like particle with mass in the few keV range. Compared to flavor-diagonal freeze-in, this mechanism enhances dark matter stability, softens stellar cooling constraints and improves the experimental sensitivity of accelerator-based searches. These scenarios can be tested by future X-ray telescopes, and in some cases will be almost entirely probed by new searches for lepton flavor violation at high-intensity experiments such as Mu3e and MEG II.

description: Traditionally double neutrinoless electronic capture is considered as a resonance process. We have fulfilled shake-off probability calculations, leading to ionization of the electron shell, in the case of 164Er. Allowance for the shake-off removes the requirement of resonance, leading to a radical increase of the capture rate. In the case of 164Er, the contribution of the new mechanism increases the capture rate by a factor of 5.6 as compared to the conventional resonance fluorescence mechanism. It also increases the probability of electron capture from higher shells, which must be foreseen in the experimental studies. Moreover, the effect of the shake-off can expand the list of candidate nuclei for experimental research. The influence of the shake-off is also expected to manifest itself in the other beta processes which are used in the studies of the neutrino nature, its mass and role in the dark matter puzzle.

Science, Metaphoric Meaning, and Indigenous Knowledge
Creators: name: Elliott, Frank
Publisher: name: Alberta Journal of Educational Research
Year: 2010

description: Western cultural approaches to teaching science have excluded Indigenous knowledges and culturally favored many non-Aboriginal science students. By asking the question “What connections exist between Western science and Indigenous knowledge?” elements of epistemological (how do we determine what is real?) and ontological (what is real?) connections can emerge for science educators. Western science as it is presented in Alberta classrooms is characterized as teaching scientism by the degree to which it excludes the presentation of other ways of knowing. The objectivity of Western science is questioned here, and aspects of Indigenous knowledge are suggested that coincide with and can support science teaching. The concept of indeterminacy and flux as suggested by Bohm (1980), Little Bear (2004), and Peat (2002) form a nexus where Western scientific epistemologies and ontologisms are congruent with Indigenous knowledge. Metaphoric meaning is suggested as one useful area of congruence for science education praxis.

Recentering the Philosophical Foundations of Knowledge: The Case of Africa With a Special Focus on the Global Role of Teachers
Creators: name: Abdi, Ali A.
Publisher: name: Alberta Journal of Educational Research
Year: 2010

description: The historical and actual marginalizations of African thought systems and knowledge constructions have been expansively responsible for the effectiveness of the dominant educational and governance systems imposed on Africa. The idea as well as the practice of these realities would conform to what Said (1993), Fanon (1967, 1968), and Memmi (1991) have called the cultural and psychosocial colonizations of both the physical and mental spaces of the conquered. The reality also speaks about the role of Europe’s most important thinkers such as Kant, Hobbes, and Voltaire, who all directly or indirectly paved the way for the projects of “de-philosophization” and “de-epistemologization” that still affect people’s lives. With the emergence of new cosmopolitanisms now creating highly multicultured societies in especially the so-called liberal democracies of the West, new contexts have also emerged of what one might counterintuitively call the “multiculturalization of knowledge marginalizations.” Thus there is an urgent need to aim for knowledge and learning multicentricities that both theoretically and pragmatically rewrite the learning trajectories of both the old colonized space and the new, still alienating multicultural classrooms. This article engages the historical and actual problematizations of the case and suggests some ideas for better possibilities that could enhance the schooling lives of current globally located learners.

Restoring a lost lineage : reinventing the Karma Kagyu scholastic tradition of Tibetan Buddhism in-exile post-1959
Creators: name: Gurung, Chulthim
Publisher: name: University of British Columbia

description: In both popular and academic discourse, Karma Kagyu Tibetan Buddhism is known for its meditation practices and sometime is considered anti-scholastic. However, I claim that the Karma Kagyu does have a historical scholastic lineage and that the Sixteenth Karmapa attempted to revive it during the twentieth century. This thesis is a critical analysis of the Karma Kagyu scholastic tradition from the medieval period to the present day. Throughout I adhere to the cross-cultural and comparative concept of “scholasticism” as defined by José Cabezón, and khepa as discussed by Sakya Pandita (1182-1251). Khepa (mkhas pa) is a crucial but ambiguous Tibetan term that includes meanings of “scholarship” and “scholasticism.” The history of the Karma Kagyu scholastic tradition can be broken into three periods: an early period of invention, a middle period of decline and loss, and a recent period of revitalization. The Third Karmapa (1303-1339) established a formal academic tradition during the fourteenth century and this tradition declined by the seventeenth century under the rule of the Fifth Dalai Lama (1617-1682). This decline was a result of the Tibetan Civil War between the Ü and Tsang regions of central Tibet and was perpetuated by a hegemonic Buddhist sectarian ideology that suppressed non-Geluk scholastics. This history explains why there are so few Karma Kagyu scholars and monastic institutes, or shédra, in-exile post-1959. It also highlights the work of the Sixteenth Karmapa (1924-1981) to restore the Karma Kagyu scholastic tradition and hybridize it with modern curricula and educational institutions during this same period but itself began to decline in 1993, negatively influenced by both the Seventeenth Karmapa succession controversy and a strong antagonism between Karma Kagyu monasticism and scholasticism. This latter tension is embodied by the difficult relations between Rumtek Monastery and Rumtek Shédra. My analysis of the Sixteenth Karmpa’s efforts to revive the scholastic tradition in-exile rely to some extent on a positive understanding of the theoretical framework of The Invention of Tradition (1983) by Eric Hobsbawm and Terence Ranger in which “invention” is not a deceptive act but a creative hybrid of old and new.

description: Taking advantage of both the low-emittance proton-beam of the Cooler Synchrotron COSY and the high momentum precision of the COSY-11 detector system, the mass distribution of the eta' meson was measured with a resolution of 0.33 MeV/c^2 (FWHM), improving the experimental mass resolution by almost an order of magnitude with respect to previous results. Based on the sample of more than 2300 reconstructed pp --> pp eta' events the total width of the eta' meson was determined to be 0.226 +- 0.017(stat.) +- 0.014(syst.) MeV/c^2.

description: In order to minimize the generalization error in neural networks, a novel technique to identify overfitting phenomena when training the learner is formally introduced. This enables support of a reliable and trustworthy early stopping condition, thus improving the predictive power of that type of modeling. Our proposal exploits the correlation over time in a collection of online indicators, namely characteristic functions for indicating if a set of hypotheses are met, associated with a range of independent stopping conditions built from a canary judgment to evaluate the presence of overfitting. That way, we provide a formal basis for decision making in terms of interrupting the learning process.
 As opposed to previous approaches focused on a single criterion, we take advantage of subsidiarities between independent assessments, thus seeking both a wider operating range and greater diagnostic reliability. With a view to illustrating the effectiveness of the halting condition described, we choose to work in the sphere of natural language processing, an operational continuum increasingly based on machine learning. As a case study, we focus on parser generation, one of the most demanding and complex tasks in the domain. The selection of cross-validation as a canary function enables an actual comparison with the most representative early stopping conditions based on overfitting identification, pointing to a promising start toward an optimal bias and variance control.
