Abstract:
In this paper, we expose some surprising connections between string theory and statistical inference. We consider a large collective of agents sweeping out a family of nearby statistical models for an [Formula: see text]-dimensional manifold of statistical fitting parameters. When the agents making nearby inferences align along a [Formula: see text]-dimensional grid, we find that the pooled probability that the collective reaches a correct inference is the partition function of a nonlinear sigma model in [Formula: see text] dimensions. Stability under perturbations to the original inference scheme requires the agents of the collective to distribute along two dimensions. Conformal invariance of the sigma model corresponds to the condition of a stable inference scheme, directly leading to the Einstein field equations for classical gravity. By summing over all possible arrangements of the agents in the collective, we reach a string theory. We also use this perspective to quantify how much an observer can hope to learn about the internal geometry of a superstring compactification. Finally, we present some brief speculative remarks on applications to the AdS/CFT correspondence and Lorentzian signature space–times.

Abstract:
This article was prepared for the Special Issue on Resampling methods for statistical inference of the 2020s. Modern algorithms such as random forests and deep learning are automatic machines for producing prediction rules from training data. Resampling plans have been the key technology for evaluating a rule’s prediction accuracy. After a careful description of the measurement of prediction error the article discusses the advantages and disadvantages of the principal methods: cross-validation, the nonparametric bootstrap, covariance penalties (Mallows’ Cp and the Akaike Information Criterion), and conformal inference. The emphasis is on a broad overview of a large subject, featuring examples, simulations, and a minimum of technical detail.

Abstract:
Summary Conformal prediction is a general method that converts almost any point predictor to a prediction set. The resulting set retains the good statistical properties of the original estimator under standard assumptions, and guarantees valid average coverage even when the model is mis-specified. A main challenge in applying conformal prediction in modern applications is efficient computation, as it generally requires an exhaustive search over the entire output space. In this paper we develop an exact and computationally efficient conformalization of the lasso and elastic net. The method makes use of a novel piecewise linear homotopy of the lasso solution under perturbation of a single input sample point. As a by-product, we provide a simpler and better-justified online lasso algorithm, which may be of independent interest. Our derivation also reveals an interesting accuracy-stability trade-off in conformal inference, which is analogous to the bias-variance trade-off in traditional parameter estimation. The practical performance of the new algorithm is demonstrated in both synthetic and real data examples.

Abstract:
Populations of isogenic embryonic stem cells or clonal bacteria often exhibit extensive phenotypic heterogeneity that arises from intrinsic stochastic dynamics of cells. The phenotypic state of a cell can be transmitted epigenetically in cell division, leading to correlations in the states of cells related by descent. The extent of these correlations is determined by the rates of transitions between the phenotypic states. Therefore, a snapshot of the phenotypes of a collection of cells with known genealogical structure contains information on phenotypic dynamics. Here, we use a model of phenotypic dynamics on a genealogical tree to define an inference method that allows extraction of an approximate probabilistic description of the dynamics from observed phenotype correlations as a function of the degree of kinship. The approach is tested and validated on the example of Pyoverdine dynamics in Pseudomonas aeruginosa colonies. Interestingly, we find that correlations among pairs and triples of distant relatives have a simple but nontrivial structure indicating that observed phenotypic dynamics on the genealogical tree is approximately conformal—a symmetry characteristic of critical behavior in physical systems. The proposed inference method is sufficiently general to be applied in any system where lineage information is available.

Abstract:
This paper considers the fragment ∃∀SO of second-order logic. Many interesting problems, such as conformant planning, can be naturally expressed as finite domain satisfiability problems of this logic. Such satisfiability problems are computationally hard (ΣP2) and many of these problems are often solved approximately. In this paper, we develop a general approximative method, i.e., a sound but incomplete method, for solving ∃∀SO satisfiability problems. We use a syntactic representation of a constraint propagation method for first-order logic to transform such an ∃∀SO satisfiability problem to an ∃SO(ID) satisfiability problem (second-order logic, extended with inductive definitions). The finite domain satisfiability problem for the latter language is in NP and can be handled by several existing solvers. Inductive definitions are a powerful knowledge representation tool, and this moti- vates us to also approximate ∃∀SO(ID) problems. In order to do this, we first show how to perform propagation on such inductive definitions. Next, we use this to approximate ∃∀SO(ID) satisfiability problems. All this provides a general theoretical framework for a number of approximative methods in the literature. Moreover, we also show how we can use this framework for solving practical useful problems, such as conformant planning, in an effective way.

Abstract:
The purpose of the present study was to investigate convergent and divergent validity of inferences from selected measures of struture, coherence, and quality for compositions. Thirty sixth-graders wrote two stories each. Each story was scored six times, for each of three constructs (structure, coherence, and quality), using two ways of measuring (reader- and text-based). Patterns in correlation matrices were examined for the extent to which they conformed to expectations which would support convergent and divergent validity. The major conclusions of the study were: (a) Overall, the findings strongly supported validity of inferences from the structure measures, called into serious question the validity of inferences from the coherence measures, and weakly supported it for inferences from the quality measures; (b) some evidence was provided for the distinctiveness of the three constructs, structure, coherence, and quality; and (c) some method/halo bias emerged in the reader-based method of assessment.

Abstract:
Knowledge compilation is a powerful technique for compactly representing and efficiently reasoning about logical knowledge bases. It has been successfully applied to numerous problems in artificial intelligence, such as probabilistic inference and conformant planning. Conditioning, which updates a knowledge base with observed truth values for some propositions, is one of the fundamental operations employed for reasoning. In the propositional setting, conditioning can be efficiently applied in all cases. Recently, people have explored compilation for first-order knowledge bases. The majority of this work has centered around using first-order d-DNNF circuits as the target compilation language. However, conditioning has not been studied in this setting. This paper explores how to condition a first-order d-DNNF circuit. We show that it is possible to efficiently condition these circuits on unary relations. However, we prove that conditioning on higher arity relations is #P-hard. We study the implications of these findings on the application of performing lifted inference for first-order probabilistic models.This leads to a better understanding of which types of queries lifted inference can address.

Abstract:
Abstract The backward-chaining inference strategy of Prolog is inefficient for a number of problems. The article proposes Contralog: a Prolog-conform, forward-chaining language and an inference engine that is implemented as a preprocessor-compiler to Prolog. The target model is Prolog, which ensures mutual switching from Contralog to Prolog and back. The Contralog compiler is implemented using Prolog's de facto standardized macro expansion capability. The article goes into details regarding the target model. We introduce first a simple application example for Contralog. Then the next section shows how a recursive definition of some problems is executed by their Contralog definition automatically in a dynamic programming way. Two examples, the well-known matrix chain multiplication problem and the Warshall algorithm are shown here. After this, the inferential target model of Prolog/Contralog programs is introduced, and the possibility for implementing the ReALIS natural language parsing technology is described relying heavily on Contralog's forward chaining inference engine. Finally the article also discusses some practical questions of Contralog program development.

ABSTRACT Near-surface seismic refraction tomography imaged the basal contact of the Upper Cambrian silica-rich Mount Simon Formation with that of the underlying Precambrian granite in central Wisconsin. The discrimination between the Mount Simon and underlying non-conformable contact with Precambrian rocks was based upon a p-wave velocity of 1,700 m/s. Refraction tomography imaged deep, broad tidal channels within the Mount Simon consistent with the inference that Mount Simon was deposited in a high-energy near-shore, probably fluvial environment. The Mount Simon is an arenite that has high commercial value.

Abstract:
We study processing and acquisition of objective information regarding qualities that people care about, intelligence and beauty. Subjects receiving negative feedback did not respect the strength of these signals, were far less predictable in their updating behavior and exhibited an aversion to new information. In response to good news, inference conformed more closely to Bayes' Rule, both in accuracy and precision. Signal direction did not affect updating or acquisition in our neutral control. Unlike past work, our design varied direction and agreement with priors independently. The results indicate that confirmation bias is driven by direction; confirmation alone had no effect.

Abstract:
The Uitpa Formation is a lithostratigraphic unit that crops out in the Guajira peninsula, northeastern Colombia in the Cocinas Basin. This formation consists mainly of marly and argillaceous mudstones of gray to light brown color, intercalated with sandstone and calcarenite beds. The lower contact with de Siamana Formation is unconformable, and at the top the contact with the Jimol Formation is conformable at Uitpa. These units contain an abundant and diverse fauna of planktic and benthic foraminifera that has not been studied in detail yet. In this research, two outcrop sections from the upper Guajira containing the Uitpa Formation were analyzed: the Pisuuluu hill and Jososuwou creek sections. Planktic foraminifera were extracted and taxonomically classified, allowing to assign an age of Chattian (Late Oligocene) (planktic foraminifera biozones O6 - O7). This investigation presents for the first time in Colombia a paleoenvironmental reconstruction integrating various methodologies using quantitative and qualitative analyses in benthic foraminifera. From these analyses an outer neritic to upper bathyal paleodepth was inferred, with environments characterized by high organic matter inputs in eutrophic conditions for both sections. Oxygenation levels were higher in the Pisuuluu hill section, represented by high diversity heterogeneous assemblages, while for the Jososuwou creek section oxygenation was very low producing stressed environments and low diversity homogeneous assemblages.

Full text
Abstract:
Recent research presented in American Antiquity (66:36-46) proposed that the prehistoric Puebloan communities of Chaco Canyon in the American Southwest conformed to a matrilocal pattern of postmarital residence. The inference of matrilocality at Chaco Canyon was based on the assumption that a number of the most likely modern descendants of the Chacoans are matrilocal, including the present-day Zuni and Hopi Indians, and that the household floor area had increased to a level indicative of female-based residence. The present study assesses these two important assumptions using biological and architectural data. Our results indicate the assumptions needed to infer matrilocal residence at Chaco Canyon might not be satisfied. The biological evidence indicates close relationships with both matrilocal and bilocal present-day populations, while the architectural evidence is more consistent with a male-based pattern of postmarital residence. Limitations to the study of postmarital residence at archaeological sites are discussed.

Abstract:
The Islamic Republic of Pakistan won its independence seventy years ago, yet its education system continues to be secular. If one of the main aims of education is to prepare the young generation for achieving national objectives, it is but imperative for Pakistan to design an education system from the Islamic perspective. Since Muhammad Iqbal is considered to be the ideologue of Pakistan and we find quite inclusive guidelines for developing a framework for an Islamic education system in Iqbal’s writing, it is imperative to explore his literature dealing with education. Two of his analogies Asrar e Khudi and Ramuz e Bikhudi are such works where we find Iqbal providing us with exhaustive recommendations for the same. The aims and directives for achieving goals of education were extracted from these two anthologies by employing qualitative method analysis and using hermeneutics approach under the supervision of a specialist on Iqbal. The results reveal that Iqbal’s concept and methodology of the development of self or individuality conformed to the approach of modern critics of contemporary education, who claim that the prevalent system is at odds with the natural human faculty of creativity.

Abstract:
Abstract In previous research comparing the Context-driven Model with the Default Model of meaning processing, the former was preferred. It predicts that contexts play an exclusively decisive role in meaning processing, whereas the latter holds that the inference of literal meaning generally goes through, unless it is subsequently defaulted or cancelled by the context it is associated with. The Standardization Model, which we added to our experiments, highlights that implicatures are figured out from standardized forms typically based on the mutual background belief and speaker’s intention. We tested whether Chinese people’s processing of the gradable adjective scale <hot, burning> conformed more to the Context-driven Model, the Default Model, or the Standardization Model. The results demonstrated that the Standardization Model is the most acceptable among the three. The findings of this study, which is the first study using the experimental paradigm on Chinese gradable adjectives, highlighted a need for further studies to investigate the same questions with different languages and cultures.

Abstract:
In this paper we consider all possible dependencies that can be built upon similarity-based fuzzy relations, that is, fuzzy functional and fuzzy multivalued dependencies. Motivated by the fact that the classical obtaining of new dependencies via inference rules may be tedious and uncertain, we replace it by the automated one, where the key role is played by the resolution principle techniques and the fuzzy formulas in place of fuzzy dependencies. We prove that some fuzzy multivalued dependency is actively correct with respect to given fuzzy relation instance if and only if the corresponding fuzzy formula is in line with the attached interpretation. Additionally, we require the tuples of the instance to be conformant (up to some extent) on the leading set of attributes. The equivalence as well as the conclusion are generalized to sets of attributes. The research is conducted by representing the attributes and fuzzy dependencies in the form of fuzzy formulas, and the application of fuzzy implication operators derived from carefully selected Frank’s classes of additive generators

Abstract:
We examined sites used by 73 caribou located by radio-tracking during spring migration through a forested travel corridor. The physical and botanical characteristics of these sites were described to find what features (if any) distinguished them from the forest at large. Raised and open aspect, sparse tree cover, free-draining soils, and a simple flora with abundant lichens were features common to all the sites, but were lacking in the denser forest around. Scores for these attributes were ordinated by multidimensional scaling of similarities and differences from site to site. Separate searings for (i) terrain features, (ii) tree cover attributes, and (iii) floristic content each yielded a single cluster of points with few outliers and no particular pattern or trend. The inference is that the sites conformed to a single type with limited variation. A profile of the distinguishing characteristics was compiled and then applied to transects through the general migration area by persons unfamiliar with it beforehand. Sites which matched the profile proved easy to identify, even though they comprised only a small proportion of the area. Sites with high scores for the most distinctive attributes had more caribou at the time of radio-tracking.

Abstract:
In this paper, we propose on-device voice command assistants for mobile games to increase user experiences even in hands-busy situations such as driving and cooking. Since most of the current mobile games cost large memory (e.g. more than 1GB memory), so it is necessary to reduce memory usage further to integrate voice commands systems on mobile clients. Therefore a need to design an on-device automatic speech recognition system that costs minimal memory and CPU resources rises. To this end, we apply cross layer parameter sharing to Conformer, named MONICA2 which results in lower memory usage for on-device speech recognition. MONICA2 reduces the number of parameters of deep neural network by 58%, with minimal recognition accuracy degradation measured in word error rate on Librispeech benchmark. As an on-device voice command user interface, MONICA2 costs only 12.8MB mobile memory and the average inference time for 3-seconds voice command is about 30ms, which is profiled in Samsung Galaxy S9. As far as we know, MONICA2 is the most memory efficient yet accurate on-device speech recognition which could be applied to various applications such as mobile games, IoT devices, etc.

Abstract:
AbstractCollaborative robots are expected to physically interact with humans in daily living and the workplace, including industrial and healthcare settings. A key related enabling technology is tactile sensing, which currently requires addressing the outstanding scientific challenge to simultaneously detect contact location and intensity by means of soft conformable artificial skins adapting over large areas to the complex curved geometries of robot embodiments. In this work, the development of a large-area sensitive soft skin with a curved geometry is presented, allowing for robot total-body coverage through modular patches. The biomimetic skin consists of a soft polymeric matrix, resembling a human forearm, embedded with photonic fibre Bragg grating transducers, which partially mimics Ruffini mechanoreceptor functionality with diffuse, overlapping receptive fields. A convolutional neural network deep learning algorithm and a multigrid neuron integration process were implemented to decode the fibre Bragg grating sensor outputs for inference of contact force magnitude and localization through the skin surface. Results of 35 mN (interquartile range 56 mN) and 3.2 mm (interquartile range 2.3 mm) median errors were achieved for force and localization predictions, respectively. Demonstrations with an anthropomorphic arm pave the way towards artificial intelligence based integrated skins enabling safe human–robot cooperation via machine intelligence.

En el presente trabajo se analizaron los efectos de un plan de entrenamiento (aprendizaje) mediante la práctica por bloques en el golpeo con la parte interna del pie en la adquisición (aprendizaje) de este fundamento técnico. La investigación fue realizada con una muestra de nueve niños entre 10 y 12 años de edad pertenecientes a un club de fútbol. El estudio se llevó a cabo con un grupo experimental conformado aleatoriamente, con el que se realizó un pretest- postest. Para efectuar la valoración se diseñó y estructuró previamente el instrumento de medición del aprendizaje de la técnica y se utilizaron registros fílmicos de cada sujeto. Para el tratamiento de la información se emplearon las medidas de tendencia central, de dispersión y de inferencia. Los resultados muestran que después de la ejecución de un plan de aprendizaje técnico (1.000 repeticiones del fundamento técnico) se presentan diferencias estadísticamente significativas en el aprendizaje del golpeo con la parte interna del pie.

Abstract:
To test an inference that the New Liskeard–Thornloe scarp (NLTS), Timiskaming graben, Ontario, is a deglacial–postglacial seismo-neotectonic fault, we collected shallow geophysical data along lines 7.2, 0.28, and 0.52 km long, located on three roads crossing the middle portion of the scarp. Data revealed a valley subsurface composed of bedrock (seismic unit a), glaciolacustrine–lacustrine deposits (units b to f), mass movement deposits (units ls 1 to ls 3), wave-worked sediments, mass wasting deposits and (or) artificial fill (unit g), and a minor occurrence of roadfill (unit h). The bedrock surface exhibits only minor undulations in the area underlying the scarp, indicating that the scarp morphology is unrelated to the underlying bedrock topography. Parallel reflectors in glaciolacustrine seismic units b and c conformably overlie the minor bedrock undulations and there is an absence of disturbed or offset zones within the reflectors underlying the scarp. This lack of disturbance or offset provides strong evidence that the scarp is not the product of deglacial–postglacial seismo-neotectonic faulting. The erosive truncation of glaciolacustrine seismic units d and e indicate that the scarp is an erosive feature cut into the glaciolacustrine deposits. It is likely a bluff formed by shoreline erosion, as is consistent with a geomorphic setting previously inundated by a large glacial lake and subsequent recessional lake stages. The non-fault origin for the NLTS limits the northern extent of the hypothesized Timiskaming East Shore Fault to within the Lake Timiskaming basin and, hence, constrains estimates of maximum rupture length.

Abstract:
Como una medida para mejorar la competitividad en el mercado de las telecomunicaciones, actualmente las empresas del sector crean nuevos servicios de valor agregado, con el fin de ampliar su portafolio de servicios y garantizar bien sea la permanencia de sus clientes o ampliar el número de suscriptores. Estos nuevos servicios deben estar soportados en los procesos de negocio definidos por el Operador Telecomunicaciones, los cuales están compuestos por tareas de operación, gestión, mantenimiento y soporte. Habitualmente los Arquitectos Telco reutilizan dichas tareas con el objetivo de optimizar los recursos de la empresa y garantizar la rápida recuperación de la inversión, amortizando en el menor tiempo posible los gastos de creación y despliegue del nuevo servicio. La reutilización de tareas Telco presenta limitaciones en cuanto a la agilidad en la selección, ya que normalmente existen cientos de tareas y se requiere de la intervención de personal técnico que lleve a cabo las funciones de recuperación, a partir de la interpretación subjetiva del proceso de negocio a implementar. Existen diferentes enfoques que pretenden automatizar la selección de recursos pero generalmente están centrados en el emparejamiento semántico de los conceptos que describen sus interfaces de acceso (entradas y salidas); sin embargo, se ha demostrado que en la aplicación de estas técnicas es omitida información relevante contenida en otros atributos, tales como los identificadores. Por esta razón, el presente trabajo propone un mecanismo para determinar la similitud semántica entre tareas que conforman procesos de negocio de telecomunicaciones. Dicho mecanismo considera dos perspectivas: la inferencia sobre la funcionalidad de las tareas especificada en los identificadores y el análisis de cobertura de sus entradas y salidas.

Abstract:
A Rasch-scaled working memory task was used to estimate the working memory capacity of adolescents with moderate mental retardation. The working memory task was calibrated using a sample of 412 children from regular mainstream classes and special education classes in primary school. The main issue of this paper concerns the usefulness of the constructed scale for children with moderate mental retardation. The Item Response model used is the Verhelst and Glas generalized Rasch-model (see e.g., Verhelst & Glas, 1995), a strong measurement model with attractive properties, such as measurement on a true interval scale on which both items and persons can be represented and the estimation of personal capacities independent of the items actually used. Because the model can be tested and the response patterns of individual persons can be analyzed, inferences can be made about the usefulness of the model for persons with moderate mental retardation. When the estimated capacity of a person is not in line with the responses given to individual items, this implies that the measure is not reliable for this person. When such a situation arises for many persons with mental retardation, this indicates that the present model is not applicable to this population; however, when the capacity estimates of persons with moderate mental retardation are reliable, this implies that working memory capacity is measured on the same dimension. In this study, the performance of adolescents with mental retardation was generally comparable to those of six- to seven-year-old normally developing children, but never surpassed complexity level 4. Their response patterns also conformed to the model. We concluded that working memory was measured on qualitatively the same dimension in both groups.

En el presente artículo, se presenta la optimización utilizando lógica difusa de un dispositivo conformado por una báscula con sensores integrados. Los cuales permiten identificar los alimentos y realizar un análisis químico, con el fin de identificar compuestos que pueden resultar nocivos para la salud de las personas. La bascula podrá ser conectada a través de bluetooth a cualquier aparato móvil, el cual utilizando una aplicación programada con la técnica de lógica difusa, le permitirá al usuario una descripción de los componentes de cualquier alimento, además de sugerir otros ingredientes que le permitan seguir una dieta más saludable y balanceada. La metodología de desarrollo se divide en tres etapas, la primera determinar las características de la bascula, luego las características del sensor y por último el desarrollo del aplicativo. La implementación del modelo está basado en la correlación de un Sistema Experto y de Lógica Difusa (Fuzzy Logic), en donde se establecen un sistema de inferencia, considerando la elección de variables de entrada y el establecimiento de tres macros que tienen evaluaciones integradas (propias de INVIMA), que posteriormente permitirán calcular los niveles de toxicidad en los alimentos. Al mismo tiempo con el fin de probar y validar el modelo, de tal modo que éste entregue resultados consistentes, se comparan resultados obtenidos en otros estudios, donde se puede evidenciar que el modelo planteado es más eficiente en un 7,57% con respecto a los demás puestos en consideración.

Objective: To analyze drug utilization (DU) pattern of antidiabetes drug (ADD) prescription in elderly type 2 diabetes mellitus (T2DM) in rural West Bengal based on 2016 World Health Organization (WHO) Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) Index. Methods: This was a prospective observational study. Prescription data of 600 elderly patients (age > 60 years) attending outpatient clinic were screened over 12 months (January 2015 to January 2016) from 5 different rural hospitals in West Bengal. Pooled data were sorted and classified in accordance with 2016 ATC/DDD WHO Index. Direct cost associated and consumption of ADD were measured as DDD/1000 patients/day. The adverse drug reactions (ADRs) related to antidiabetic medicines were monitored. Results: During the study period, mean age of patients recorded was 66.4 ± 5.0 years, with 66.6% (n = 396) having history of T2DM > 5 years. Follow-up encounters (n = 2328) revealed metformin (94.67%), sulfonylureas (SUs) (50.54%), pioglitazone (24.22%), voglibose (22.50%), insulin (9.75%), and acarbose (6.82%) to be more prevalent, constituting DU 90% (92.01%). Combination of metformin plus SU was recorded in most of the patients (56%). Insulin, however, was found to be an underutilized class ( P < .005). The DDD/1000 patients/day of metformin (2.918), glimepiride (1.577), and gliclazide (0.069) conformed to 2016 WHO ATC/DDD Index. The total ADD consumption during study period was 5.03 DDD/1000 patients/day. The average drug cost per encounter per day was Rs 11.24 ± 2.01. Nineteen ADRs were reported and their descriptions were found to be of hypoglycemia (n = 9), pedal edema (n = 2), and gastrointestinal upsets (n = 8). Target glycemic status was achieved in 40% monthly follow-up encounters. Low-store drug availability and poor compliance to treatment (>60%) were major determinants. Lack of regular aerobic exercises (>85%) and proper knowledge regarding medical nutrition therapy (MNT) (>80%) and low average consultation time (3.5 ± 0.6 minutes) were important contributing factors. Conclusions: The study exhibited increased utilization of 2 drug combinations of oral ADD and lower utilization of insulin during study period. Such inferences merit further exploration.

Abstract:
It has been nearly fifty years since Tom Pearce devised a type of element ratio diagram that isolates the effects of crystal fractionation and accumulation (sorting) hidden in the chemistry of a suite of igneous rocks. Here, we review the guiding principles and methods supporting the Pearce element ratio paradigm and provide worked examples with data from the Mauna Ulu lava flows (erupted 1970–1971, Kilauea Volcano, Hawaii). Construction of Pearce element ratio diagrams requires minimum data; a single rock analysis can suffice. The remaining data test the model. If the data fit the model, then the model is accepted as a plausible or likely explanation for the observed chemical variations. If the data do not fit, the model is rejected. Successful applications of Pearce element ratios require the presence and identification of conserved elements; elements that remain in the melt during the processes causing the chemical diversity. Conserved elements are identified through a priori knowledge of the physical-chemical behaviour of the elements in rock-forming processes, plots of weight percentages of pairs of oxides against each other, or by constant ratios of two elements. Three kinds of Pearce element ratio diagrams comprise a model: conserved element, assemblage test, and phase discrimination diagrams. The axial ratios for Pearce ratio diagrams are combinations of elements chosen on the basis of the chemical stoichiometry embedded in the model. Matrix algebra, operating on mineral formulae and analyses, is used to calculate the axis ratios. Models are verified by substituting element numbers from mineral formulae into the ratios. Different intercepts of trends on Pearce element ratio diagrams distinguish different magma batches and, by inference, different melting events. We show that the Mauna Ulu magmas derive from two distinct batches, modified by sorting of olivine, clinopyroxene, plagioclase and, possibly, orthopyroxene (unobserved).RÉSUMÉIl y a près de cinquante ans Tom Pearce a conçu un genre de diagramme de ratio d’éléments qui permet d’isoler les effets de la cristallisation fractionnée et de l'accumulation cristalline (tri) au sein de la chimie d'une suite de roches ignées. Dans le présent article, nous passons en revue les principes et les méthodes étayant le paradigme de ratio d’éléments de Pearce, et présentons des exemples pratiques à partir de données provenant de coulées de lave du Mauna Ulu (éruption 1970–1971 du volcan Kilauea, Hawaii). La confection des diagrammes de ratio d’éléments de Pearce requière un minimum de données; une seule analyse de roche peut suffire. Les données restantes servent à tester le modèle. Si les données sont conformes au modèle, alors le modèle est accepté comme explication plausible ou probable des variations chimiques observées. Si les données ne correspondent pas, le modèle est rejeté. Les applications réussies des ratios d’éléments de Pearce requièrent la présence et l'identification d’éléments conservés; éléments qui demeurent dans la masse fondue au cours des processus causant la diversité chimique. Les éléments conservés sont identifiés par la connaissance a priori du comportement physico-chimique des éléments dans les processus de formation des roches, le positionnement sur la courbe des pourcentages pondérés de pairs d'oxydes les uns contre les autres, ou par des ratios constants de deux éléments. Trois types de diagrammes de Pearce de ratio d’éléments constituent un modèle: élément conservé, test d'assemblage, et diagrammes de phase discriminant. Les ratios axiaux pour les diagrammes de ratio d’éléments de Pearce sont des combinaisons d'éléments choisis sur la base de la stœchiométrie inhérente au modèle. L’algèbre matricielle, appliquée à des formules minérales et à des analyses, est utilisée pour calculer les ratios axiaux. Les modèles sont vérifiés en utilisant les nombres d’élément des formules minérales dans les ratios. Différentes intersections dans les diagrammes de ratios d’éléments de Pearce distinguent différents lots de magma et, par inférence, différentes coulées. Nous montrons que les magmas de Mauna Ulu proviennent de deux lots distincts, modifiés par l’extraction de l'olivine, de clinopyroxène, de plagioclase et, éventuellement, orthopyroxène (non observé).

La investigación arroja consenso en los equipos directivos en que las demandas y las características de las situaciones que vivencian con las familias desbordan y exceden a su formación como docentes y como directivos. La importancia del papel de las familias en los logros de los estudiantes resaltada por la bibliografía actual contrasta con las difcultades del trabajo en territorio planteadas por los equipos directivos. CONSTRUCTION OF THOUGHT IN PUBLIC POLICIES AND ARTISTIC PROCESSES WITH CHILDHOODS: REFLECTIONS FROM THE ARTISTIC INITIATION PROGRAM – PIÁ. Joice Rodrigues de Lima, UDESC, Brasil. I propose here to articulate refections about the structuring of public policies in the feld of arts and childhoods, considering some actions carried out in PIÁ - Artistic Initiation Program, between 2008 and 2018, specifcally. This program has been taking place for more than 14 years, uninterruptedly, in the four macro-regions of the city of São Paulo - SP, with management of the Secretariat of Culture in partnership with Education. Its practices are with and for children and adolescents between 5 and 14 years old and artists educators of the languages of music, theater, literature, visual arts and dance, with the present participation of family members, managers and communities of the territories where the experiences are established. In this context, among many relevant aspects for this refection, it is highlighted, among its structuring axes, a look at the Childhoods that consider them as people of rights, purposers and artistic creators, as the proposition of creation processes that respect the temporalities of childhood and that value the horizontality, dialogue, respect and reception in the relations between educators and children, participation and defagration of artistic processes. Considering that these factors reinforce a confrontation with hegemonic powers, there is a need to think about ways to build public policies that establish actions committed to guaranteeing practices in art and education that prioritize the protagonism and participation of children. In this sense, the creation of public policies that support such participatory axes may be a path towards more respectful processes in relation to the participation of children and adolescents in society, in the public sphere, and through artistic experiences. In the construction of this thought, I will use as a foundation mainly documents that relate PIÁ’s own experience in its practices and attempts to enable the approval of a law that would make it an efective public policy in the city, as well as the contributions of researchers such as Anete Abramowicz, Maria Walburga dos Santos and Vera M. Ferrão Candau, in the feld of Latin American Sociology of Childhood and Manfred Liebel and the approach to the concept of participation and child protagonism. ERRORES ASOCIADOS A OPERACIONES ADITIVAS CON FRACCIONES: UN ESTUDIO EXPLORATORIO CON ESTUDIANTES DE SECUNDARIA. Wilmer Ríos-Cuesta, Facultad de Educación y Pedagogía, Universidad del Valle- Omar Harry Asprilla-Mena, Facultad de Ciencias Sociales y Humanas, Universidad de Medellín. Artículo de investigación. Se presenta un estudio de casos exploratorio de naturaleza cualitativa y corte descriptivo situado en un paradigma interpretativo, cuyo propósito fue identifcar los errores asociados a las operaciones aditivas con fracciones, de estudiantes, entre los 11 y 16 años, que cursan séptimo grado de secundaria de una institución educativa pública del municipio de Quibdó. La muestra estuvo conformada por ciento noventa y cinco estudiantes a las cuales se les aplicó una evaluación diagnóstica para verifcar su nivel de comprensión sobre esta temática en particular. Se parte del hecho de que los Derechos Básicos de Aprendizaje en Colombia señalan que, en este grado, los estudiantes pueden resolver problemas que involucran diversas operaciones con racionales en distintos contextos. Los resultados muestran que las estudiantes realizan sumas de los numeradores y denominadores como si fueran dos números enteros independientes, se identifcó también que cuando las fracciones tienen el mismo numerador lo que hacen las estudiantes es mantenerlo y sumar los denominadores. Asimismo, se comenten errores al usar algoritmos, pues no se tienen en cuenta si las fracciones son homogéneas o heterogéneas y no se ofrece como respuesta una fracción irreducible. Se concluye que las estudiantes comenten errores que permiten inferir una falta de comprensión sobre cómo se resuelven operaciones que implican sumar o restar fracciones, así como también, una difcultad para comprender el signifcado del concepto de fracción de acuerdo con la situación. CÓMO LA EXPERIENCIA ARTÍSTICA AMPLÍA NUESTRA COMPRENSIÓN DEL MUNDO. César Augusto Cepeda Rodríguez, Universidad Pedagógica Nacional. Artículo de refexión generativa. Expone los hallazgos e inquietudes abordadas en el libro ‘El arte de vivir y vivir con el arte. Cómo la experiencia artística amplía nuestra comprensión del mundo’, publicado por la editorial Aula de Humanidades en el mes de julio del 2022 en Bogotá. En primer lugar, quisiera proponer una serie de refexiones que han motivado en los últimos años la investigación que subyace al libro y a continuación me extenderé presentado las secciones y los contenidos de este. UNIVERSITY MANAGEMENT PERSPECTIVES: A systematic literature review through Bibliometrix. Andrea Mosquera-Guerrero. Edward Enrique Escobar-Quiñonez. The university is a key actor in the creation of knowledge that must respond to the demands of diferent interest groups that asked pertinent responses and in line with global trends; so, its management has become, over time, a complex activity. Based on the above, this work is presented, which aims to publicize trends in university management through the review of the Web of Science and Scopus databases. The records obtained were analyzed using Graph theory and tools such as Bibliometrix. The results allowed identifying four perspectives: a. technology transfer and university entrepreneurship; b. educational model; c. Change management in academic institutions and d. Interest groups. Through a network analysis, it was determined that the most relevant authors are Henry Etzkowitz, Mario Raposo and G.E. Zborovsky. For its part, the region with the highest production in the subject is the United Kingdom and it is pertinent to note that the research carried out allows us to appreciate that the subject is in the boom phase. EDUCACIÓN MATEMÁTICA Y CIUDADANÍA EN BÁSICA PRIMARIA: EXPERIENCIA DE UN PROYECTO PEDAGÓGICO DE AULA SOBRE HÁBITOS SALUDABLES. Artículo de investigación. Sergio Adrián García Cruz, Normal Superior Fabio Lozano Torrijos de Falan. Se presenta una experiencia de innovación en la enseñanza de las matemáticas en básica primaria desarrollada en una Escuela Normal Superior Colombiana (ENS). La experiencia fue llevada a cabo por maestros en formación inicial y docentes de las asignaturas didáctica de las matemáticas y didáctica del lenguaje que hacen parte del programa de formación complementaria (PFC). Los participantes diseñaron un proyecto pedagógico de aula PPA (Carrillo, 2001) para la enseñanza de las matemáticas, con un enfoque de ciudadanía (Callejo, 2010). El PPA se orientó hacia la refexión sobre los hábitos de vida saludables. Se desarrollaron 7 sesiones de clase, cada una de 3 horas, con estudiantes de grados primero y segundo de primaria de diferentes escuelas que hacen parte de la ENS. La experiencia permitió que los estudiantes de las escuelas refexionaran sobre la importancia de manejar hábitos de vida saludable, mientras que desarrollaban competencias matemáticas. Algunas de las actividades realizadas con los niños consistieron en: encuestas sobre hábitos saludables, preparación de una receta, lectura de información cuantitativa en etiquetas de diferentes productos, patrones geométricos en secuencias de baile, medición del ritmo cardiaco y ruleta de las emociones. EDUCACIÓN INCLUSIVA: LA DISLEXIA Y LA EXCLUSIÓN EDUCATIVA Y SOCIAL. Carina Acosta Mendoza, Universidad Autónoma de Ciudad Juárez, México. Artículo de investigación. La dislexia refere un problema en la adquisición de la lectura y la escritura. Un niño que presenta dislexia piensa diferente y percibe las cosas de una manera distinta. Según la UNAM (Universidad Nacional Autónoma de México), el 17% de todos los niños en el mundo presentan dislexia. En México hay una lucha y necesidad por entender la dislexia, por defnirla dentro de las aulas, detectarla y tratarla. En el momento en que un profesor no entiende la dislexia y no la detecta, limita el aprendizaje de un niño que la padece, y por lo tanto lo segrega y excluye. Es importante mencionar que el problema no se queda solo en la escuela. La exclusión educativa es entendida como un fenómeno asociado al escaso acceso al sistema educativo, que provoca segregación y exclusión educativa al no contar con herramientas para entender lo que representa la educación para todos. AVANCES EN DERECHOS HUMANOS: RECONOCIMIENTO DEL MATRIMONIO CIVIL IGUALITARIO EN LA LEGISLACIÓN ECUATORIANA. Ximena María Torres Sánchez - Carmen Georgina Puchaicela Huaca. Artículo de investigación. La histórica republicana de nuestro país, data que hemos vivido en un proceso de varias Constituciones políticas, cada una de ellas representaba el fel anclaje al conservadurismo y liberalismo, apegado al modelo de matrimonio representativo de la Antigua Roma. Es, por tanto, que el modelo de matrimonio heterosexual, se ha visto representado en todas nuestras Constituciones, e inclusive en la moderna Constitución del año 2008, que es fel sinónimo del “garantismo”. Por ello, dentro del presente artículo científco, se denota a prima facie la vulneración de los derechos a los grupos denominados LGBTI en nuestro contexto normativo; y por otro lado se visualizará como un Instrumento Internacional de los Derechos Humanos-CIDH-, mediante una Opinión Consultiva- OC- 24/17-, exteriorizo a todos sus Estados suscritos al Convenio, la no discriminación e igualdad frente a la fgura tradicional del matrimonio a las parejas homosexuales. Finalmente, se dará el estudio a la Sentencia Nº 10-18-CN/19 de nuestra Corte Constitucional, la cual tomo esta opinión consultiva como vinculante, y mando a reformar en nuestro contexto normativo a la “institución jurídica” del matrimonio, en aras de respetar el modelo constitucional vigente, que toma a los Instrumentos Internacionales de D.D.H.H, en igual jerarquía que nuestra Constitución. LA SELECCIÓN DE NIÑAS PARA EL LEVANTAMIENTO DE PESAS. RETO DEL PROCESO DE ENSEÑANZA-APRENDIZAJE DE EDUCACIÓN FÍSICA. Yunia Pérez Cruz, Universidad de Ciencias Holguín, Holguín, Cuba. Artículo de investigación dirigido a valorar el objeto como proceso de enseñanza-aprendizaje y su infuencia en el deporte de levantamiento de pesas para niñas en edades de11-12 años Para ello se realiza un acercamiento al origen y concepción de este deporte, así como a la manera en que las féminas son acogidas por la sociedad como practicantes. El acercamiento a dicha praxis social requirió el uso los métodos teóricos Histórico-lógico, Analítico–sintético, Inductivo-deductivo, métodos empírico, observación, entrevista, encuesta, métodos estadísticos descriptivos e inferencial, que posibilitaron constatar la manifestación de este fenómeno en la actualidad. Con este trabajo se evidencia que el interés por el deporte en las niñas no es impedimento, existen limitaciones que impiden el progreso en la selección deportiva como son Carencias de acciones que sustentan la selección deportiva en niñas para el levantamiento de pesas en el municipio Holguín, En la bibliografía revisada no se ha encontrado una estrategia pedagógica de la selección deportiva en niñas para la práctica del levantamiento de pesas, No se desarrolla el proceso de selección inicial con la calidad y rigor necesario de acuerdo a las exigencias establecidas, nos vemos en necesidad de establecer un mecanismo que permitas una correcta selección de estas para el deporte. DE LA RESPONSABILIDAD SOCIAL EMPRESARIAL Y LA ÉTICA GERENCIAL AL MODELO GUANXI. Cecilia Garzón Daza- Alba Marcela Jaimes Reyes - Misael Tirado Acero. Grupos de Investigación: EDUPRO, FUSM, GIGAS, UPTC, RESCYPP, UMNG, UGC. Análisis documental a través de investigaciones científcas realizadas en el ámbito de los negocios con la fnalidad de introducir el Guanxi como respuesta ante problemas hallados en la implementación de RSE y la ética empresarial. Es así, que el Guanxi entendido como un aspecto cultural chino resalta la importancia de los vínculos laborales a través del fortalecimiento de la apariencia social, las emociones y los favoreces recíprocos; nutre la ética empresarial de los vínculos laborales colaborando en la relación entre ética empresarial y desempeño laboral. A su vez, el Guanxi permite comprender los favores recíprocos de la RSE y la apuesta ética de cara a la apariencia social aportando en el fortalecimiento de esta.

Full text
Abstract:
Abstract We propose a new inference framework called localized conformal prediction. It generalizes the framework of conformal prediction by offering a single-test-sample adaptive construction that emphasizes a local region around this test sample, and can be combined with different conformal scores. The proposed framework enjoys an assumption-free finite sample marginal coverage guarantee, and it also offers additional local coverage guarantees under suitable assumptions. We demonstrate how to change from conformal prediction to localized conformal prediction using several conformal scores, and we illustrate a potential gain via numerical examples.

Full text
Abstract:
Abstract We consider the problem of distribution-free predictive inference, with the goal of producing predictive coverage guarantees that hold conditionally rather than marginally. Existing methods such as conformal prediction offer marginal coverage guarantees, where predictive coverage holds on average over all possible test points, but this is not sufficient for many practical applications where we would like to know that our predictions are valid for a given individual, not merely on average over a population. On the other hand, exact conditional inference guarantees are known to be impossible without imposing assumptions on the underlying distribution. In this work, we aim to explore the space in between these two and examine what types of relaxations of the conditional coverage property would alleviate some of the practical concerns with marginal coverage guarantees while still being possible to achieve in a distribution-free setting.

Physics in Medicine & Biology, May 11, 2022. http://dx.doi.org/10.1088/1361-6560/ac6ebc.

Full text
Abstract:
Abstract Proton therapy requires accurate dose calculation for treatment planning to ensure the conformal doses are precisely delivered to the targets. The conversion of CT numbers to material properties is a significant source of uncertainty for dose calculation. The aim is to develop a physics-informed deep learning (PIDL) framework to derive accurate mass density and relative stopping power (RSP) maps from dual-energy computed tomography (DECT) images. The PIDL framework allows deep learning (DL) models to be trained with a physics loss function, which includes a physics model to constrain DL models. Five DL models were implemented including fully connected neural networks (FCNN), dual-FCNN (DFCNN), and three variants of ResNet: ResNet-v1 (RN-v1), ResNet-v2 (RN-v2), and dual-ResNet-v2 (DRN-v2). Two empirical DECT models were implemented to compare with the PIDL method. An artificial neural network (ANN) and the five DL models trained with and without physics loss were explored to evaluate the PIDL framework. DL training data were from CIRS electron density phantom 062M (Computerized Imaging Reference Systems, Inc., Norfolk, VA). The performance of DL models was tested by CIRS adult male, adult female, and 5-year-old child anthropomorphic phantoms. For density map inference, the physics-informed RN-v2 was 3.3%, 2.9% and 1.9% more accurate than ANN for the adult male, adult female, and child phantoms. The physics-informed DRN-v2 was 0.7%, 0.6%, and 0.8% more accurate than DRN-v2 without physics training for the three phantoms, respectfully. The results indicated that physics-informed training could reduce uncertainty when ANN/DL models without physics training were insufficient to capture data structures or derived significant errors. DL models could also achieve better image noise control compared to the empirical DECT parametric mapping methods. The proposed PIDL framework can potentially improve proton range uncertainty by offering accurate material properties conversion from DECT.

Full text
Abstract:
Extracting the temporal structure of sequences of events is crucial for perception, decision-making, and language processing. Here, we investigate the mechanisms by which the brain acquires knowledge of sequences and the possibility that successive brain responses reflect the progressive extraction of sequence statistics at different timescales. We measured brain activity using magnetoencephalography in humans exposed to auditory sequences with various statistical regularities, and we modeled this activity as theoretical surprise levels using several learning models. Successive brain waves related to different types of statistical inferences. Early post-stimulus brain waves denoted a sensitivity to a simple statistic, the frequency of items estimated over a long timescale (habituation). Mid-latency and late brain waves conformed qualitatively and quantitatively to the computational properties of a more complex inference: the learning of recent transition probabilities. Our findings thus support the existence of multiple computational systems for sequence processing involving statistical inferences at multiple scales.

Abstract:
Introducción. Esta investigación abordó la comprensión intuitiva por parte de preescolares del movimiento rectilíneo y de algunas variables que lo afectan, y el tipo de argumentos utilizados cuando se justifican estados de conocimiento relacionados. Una primera hipótesis de trabajo era que la resolución de situaciones de tipo práctico y funcional estaría basada en procesos de autorregulación. Una segunda hipótesis de trabajo era que la información de retorno que proveen las situaciones debería modificar sus niveles de comprensión epistemológica.Método. La muestra estuvo conformada por 40 niños y niñas con una edad entre 5.0 y 5.5 años de edad seleccionados al azar, de tres instituciones de educación preescolar de carácter privado de Cali (Colombia), y asignados a dos grupos. El material experimental consistió en cuatro situaciones isomorficas basadas en una tarea de Chen y Klahr (1999).Resultados. Los datos apoyan la primera hipótesis, el promedio de acciones aumentó significativamente entre sesiones, las estrategias emprendidas por los niños se organizaron en series más complejas y con una efectividad mayor. No se encontró un apoyo empírico a la segunda hipótesis, la mayoría de los argumentos utilizados muestran una estabilidad en la forma como describen el conocimiento de los personajes de la situación.Discusión. En las verbalizaciones de los niños se identificó un proceso de autorregulación, pasando de mencionar las acciones emprendidas sobre el material, a controlar las acciones anticipadamente. Se discuten posiciones como las de Schauble (1996) que afirman que los preescolares son renuentes a abandonar estrategias a pesar de su inutilidad. La actividad no resultó ser efectiva para transformar los argumentos utilizados y por ende sus niveles de comprensión epistemológica.

Este análisis realizado por los estudiantes del Programa de Maestría en Enfermería tiene como propósito: explorar los elementos teóricos que surgen en el Modelo de Sistemas de Neuman, para contextuar los conceptos que subyacen de la propuesta en cuestión. Inicialmente se abordan antecedentes de Betty Neuman, posteriormente se plasman las áreas disciplinares en las que se basa (psicológica, filosófica y biológica), y se finaliza con la inferencia de algunos conceptos con los que la autora constituye su Modelo. Dentro del área Psicológica se encuentra la Teoría de Gestalt, del Estrés y la Situación en Crisis, en la Filosófica se ubica la Concepción de la Naturaleza Humana y la Visión Cosmogénica y en la Biológica se encuentra la Teoría de Sistemas. Esta última junto con la del Estrés y de Gestalt conforman gran parte del modelo donde la persona es el eje central del cuidado. Conclusión: El modelo por su estructura psicológica, filosófica y biológica sustentan la posibilidad de brindar un cuidado de enfermería integral. Este análisis ofrece al alumno de posgrado profundizar en las raíces teóricas permitiéndole reflexionar sobre el conocimiento enfermero y la práctica.

Abstract:
El artículo tiene como objetivo describir una metodología de evaluación y selección de proveedores basada en un sistema de inferencia difusa (FIS) para el sector minería del oro. Con base en una revisión de la literatura, se desarrolla un sistema difuso conformado por la caracterización del proceso de compras, variables de entrada y salida, funciones de pertenencia, reglas difusas, métodos de agregación y defusificación, e incluye un modelo de ponderación de factores para la generación de reglas difusas. El FIS propuesto se modela en Matlab® y se valida en una compañía de minería de oro ubicada en el distrito minero de Ataco-Payandé, Colombia. Con los resultados se encuentra que el FIS apoya el proceso de toma decisiones y aumenta las capacidades para la evaluación y selección de proveedores al utilizar modelos cuantitativos, variables lingüísticas y reglas difusas que involucran incertidumbre y ambigüedad. De esta manera, se contribuye al mejoramiento de empresas mineras, donde el proceso de compras y la gestión de proveedores son componentes críticos del sistema logístico minero.

Abstract:
AbstractWe investigated recent changes in spatial patterning of fen and bog zones in five boreal aapa mire complexes (mixed peatlands with patterned fen and bog parts) in a multiproxy study. Comparison of old (1940–1970s) and new aerial images revealed decrease of flarks (wet hollows) in patterned fens by 33–63% in middle boreal and 16–42% in northern boreal sites, as lawns of bog Sphagnum mosses expanded over fens. Peat core transects across transformed areas were used to verify the remote sensing inference with stratigraphic analyses of macrofossils, hyperspectral imaging, and age-depth profiles derived from 14C AMS dating and pine pollen density. The transect data revealed that the changes observed by remote sensing during past decades originated already from the end of the Little Ice Age (LIA) between 1700–1850 CE in bog zones and later in the flarks of fen zones. The average lateral expansion rate of bogs over fen zones was 0.77 m y−1 (range 0.19–1.66) as estimated by remote sensing, and 0.71 m y−1 (range 0.13–1.76) based on peat transects. The contemporary plant communities conformed to the macrofossil communities, and distinct vegetation zones were recognized as representing recently changed areas. The fen-bog transition increased the apparent carbon accumulation, but it can potentially threaten fen species and habitats. These observations indicate that rapid lateral bog expansion over aapa mires may be in progress, but more research is needed to reveal if ongoing fen-bog transitions are a commonplace phenomenon in northern mires.
