Full textAbstract:
We propose a whole-class view of microworld design, in which the total ecology of students, technology, and teacher is considered by the decisions and choices of the design. Through a case-study analysis of a classroom implementation, we illustrate a dynamic geometry microworld designed using such an approach and attempt to identify both the effects such an approach has on student affect and participation and the roles that educational technology fills in such a social context. We argue that whole-class microworld design not only has practical benefits in terms of classroom time and management, but also develops social interactions conducive to educative learning experiences.

Student government has a unique role in medical schools, where it can function to strongly nurture the well-being of a class. Student body representatives have a better understanding of the interests of medical students and the adversity they face. Thus, the student government is in a prime position to make positive change in the lives of their classmates with help from the school administration. This article explores these ideas and is written from the perspective of the co-presidents of the student body at a northeast medical school.

Purpose After interviewing teachers about their beliefs on discussion, the author observed four English teachers as they led class discussions. The purpose of this study is to see what kinds of discussion were happening, and what teachers were doing to facilitate those discussions. Design/methodology/approach The author observed six English class sessions with discussion as a technique and transcribed each. To analyze the discussion events (DEs), the author focused on the addressivity of the teachers’ comments, and plotted the DEs on a four-quadrant system of analysis. The quadrants helped to move beyond the value-laden dichotomy between monologic and dialogic discussion, and to better understand what teachers are doing. Findings The majority of class sessions were classified as convergent-active but teachers used a variety of discussions. In particular, teachers were concerned about control, so they used three techniques to keep procedural control as follows: taking over the discussion, creating specific procedures and using the Initiation-Response-Evaluation format in different ways. Originality/value Instead of focusing on a dichotomy this method of analysis opens up the possibility for labeling different kinds of dialogic instruction, like the teacher-as-conductor form of convergent-active discussions. This can help teachers understand that addressivity and purpose matter as they create their discussions but also that various forms of discussion are necessary in the classroom. Incorporating dialogic instruction has been difficult for teachers; this method can help describe what they are doing while not devaluing the kinds of discussion that are taking place.

AbstractThere is a wide range of activity in the higher education sector labelled ‘students as partners’ and ‘co-creation in learning and teaching’. Several frameworks have been proposed to map and categorise existing partnership and co-creation roles, activities, research, and practice. In this paper, I synthesise some of these frameworks to illustrate how the predominant focus in the international literature has been on partnership projects that select small groups of often already super-engaged or privileged students to participate. In contrast, co-creation in learning and teaching, embedded within the curriculum and involving a whole class of students, has been largely overlooked. I explore the potential of co-creating learning and teaching with a whole class of students (including face-to-face, blended, and online settings, and including lectures, tutorials, laboratories, and other methods of teaching); in other words, it is co-creation integral to students’ programmes and courses of study. I argue that whole-class approaches to co-creation may be inherently more inclusive of students than other approaches to co-creation and that this approach both relies upon, and contributes towards, building positive relationships between staff and students, and between students and students. I explore some of the challenges of whole-class co-creation in learning and teaching, and I also argue that the benefits suggest this is currently an underutilised and researched approach internationally.

Full textAbstract:
Many legal regimes allow for the award of aggregate damages in collective or class claims. That is to say, an award may be made reflecting the losses of the class as a whole, with little or no information as to the losses suffered by individual class members. Economists are able to calculate damages at a class level without complete individual data by applying two different but not mutually exclusive sets of methodologies, which we refer to as ‘top-down’ and ‘sample-based’ approaches. This article discusses some of the advantages and pitfalls that may arise in estimating aggregate damages under each approach, and illustrates some circumstances in which the process of aggregation may lead to upward or downward bias in the estimate of total loss. We also compare the relative merits of each approach, and consider some of the practical steps by which such biases may be avoided.

Full textAbstract:
In the last decade an area of urban history receiving increasing attention has been that of crime and, in particular, nineteenth-century crime. For those social scientists whose main interest is the study of lower-class life the study of crime has become increasingly fashionable. However, the study of crime is the study of the whole of society and the relationship of the various classes within that society. That law-makers create law-breakers is axiomatic and the study of crime is, therefore, not just the study of criminals but also of the institutions which defined them as criminals. For too long it has been implied that studying criminals is the study of a subset of lower-class life. This is a reflection of the fact that research is largely a middle-class occupation and so researchers bring to their work their own middle-class perception of society. The result is the automatic acceptance that crime consists purely of larceny, burglary, assault, rape and murder while overlooking the middle-class crimes of fraud, embezzlement, tax evasion, offences against the Companies Acts, Consumer Protection Acts and Factory Acts.

Purpose – The health-promoting schools (HPSs) framework has emerged as a promising model for promoting school connectedness in the school setting. The purpose of this paper is to explore the potential for food practices to promote school connectedness within a HPSs framework. Design/methodology/approach – This study explores food practices within a New Zealand secondary school by using an ethnographic methodology, with interviews and observations, to explore in-depth the range of food practices that occurred within the school across a whole school year. Thematically the data were ready for school connectedness indicators across the recorded events, and categorically the practices were coded according to their level of occurrence within the HPS framework. Findings – The findings showed that food practices occurred across class- and school-level organisation, ethos, environment, and community partnerships, and indicated that they may be valuable assets for a HPS approach to school connectedness. By integrating the findings of the present study with previous literature the authors suggest a HPS framework for promoting school connectedness through food practices. Originality/value – This paper contributes to the emerging research on whole-school approaches to building school connectedness, and provides a first contribution on the value of food practices for school connectedness.

Full textAbstract:
Context: Scaffolding is a form of process-adaptive learning support that is relevant in numerous contexts, including informal learning, workplace learning as well as school teaching. While scaffolding can be well conceptualised for individual learning situations (especially for tutoring situations), there is a difficulty in measuring process adaptivity in heterogeneous learning groups, such as school classes. Approach: In this paper, we develop a measurement method that targets the deep structure of teaching and learning in whole class settings. Processes of shared knowledge constructions are taken into account, since whole-class-scaffolding (WCS) means to shape and develop common or joint knowledge spaces rather than to scaffold a multitude of individual construction processes at the same time. To achieve a coding procedure for WCS interactions, we integrate scaffolding principles and principles of dialogic teaching and explicated a set of rules that can be correlated to the quality of WCS-episodes rated on distinct Likert scales. Results: The measurement method developed in the paper provides a solution to the problem of how to measure process-adaptive learning support that is not only related to individual learners, but is directed at a heterogeneous group of learners in which different support needs may be present simultaneously. The coding procedure systematically links scaffolding principles and principles of dialogic teaching and enables us to capture the dynamics of teaching and learning processes in larger group settings. In this respect, concepts such as joint- and common space, representing entities to which WCS refers, are operationalised. Conclusions: When methods for measuring the dynamics of teaching and learning processes are available, research on instructional support is no longer limited to global ratings of whole learning units. Furthermore, the codings allow for a more fine-grained analysis of trajectories of scaffolding interactions. Such an analysis reveals information about local specifics of WCS that can explain further learning differences between students and that can be used to derive implications for effective instructional techniques.

Full textAbstract:
While African, Caribbean, and Black (ACB) mothers living with HIV in Canada are required to follow public health guidelines by exclusively formula feeding their infants, they also face cultural expectations from peers and family members to breastfeed. They face multiple challenges because of their race, ethnicity, gender, class, and geographical location, among other factors. Previously published studies on this subject did not analyze how the intersectionality of these factors impacts Black mothers’ infant feeding experiences. In this article, we discuss the infant feeding practices of Black mothers living with HIV in Ottawa (Canada). We followed a qualitative methods research design that utilized intersectionality and a community-based participatory research approach. We used the intersectionality framework as a lens to analyze the complex mesh of determinants influencing motherhood experiences of ACB women living with HIV. Being a Black/ACB mother while living with HIV is a “whole story” permeated with cutting-across issues such as race, class, gender, socio-political, and cultural contexts. These issues are interwoven and often difficult to unravel. Multiple layers of structural determinants of Black/ACB women’s HIV vulnerability and health are described. Intersectionality is important for an in-depth understanding of societal power dynamics and their impact on women’s health inequities.

Full textAbstract:
This paper proposes a novel approach for selecting a subset of features in semi-supervised datasets where only some of the patterns are labeled. The whole process is completed in two phases. In the first phase, i.e., Phase-I, the whole dataset is divided into two parts: The first part, which contains labeled patterns, and the second part, which contains unlabeled patterns. In the first part, a small number of features are identified using well-known maximum relevance (from first part) and minimum redundancy (whole dataset) based feature selection approaches using the correlation coefficient. The subset of features from the identified set of features, which produces a high classification accuracy using any supervised classifier from labeled patterns, is selected for later processing. In the second phase, i.e., Phase-II, the patterns belonging to the first and second part are clustered separately into the available number of classes of the dataset. In the clusters of the first part, take the majority of patterns belonging to a cluster as the class for that cluster, which is given already. Form the pairs of cluster centroids made in the first and second part. The centroid of the second part nearest to a centroid of the first part will be paired. As the class of the first centroid is known, the same class can be assigned to the centroid of the cluster of the second part, which is unknown. The actual class of the patterns if known for the second part of the dataset can be used to test the classification accuracy of patterns in the second part. The proposed two-phase approach performs well in terms of classification accuracy and number of features selected on the given benchmarked datasets.

AbstractThe traditional format for teaching courses to undergraduate students has long been that of lecture when professors speak and students listen. However, as times have evolved so too have the pedagogical methods in the classroom. In teaching a course on diversity and discrimination in the society, this instructor opted to combine several teaching methods as a means of not only conveying the substantive material to the class but, more importantly, engaging the students at an interactive learning level. By combining traditional lecture with watching/discussing documentaries and incorporating structured student debate, a dynamic learning environment was created. As a result of incorporating the students into every aspect of the class, the students learned from both the instructor and students alike. Thus, the use of this multifaceted approach created a positive and engaging learning environment for the whole class.

Full textAbstract:
Students in a college literature class have been formed by conflicting approaches to literary pedagogy. The Common Core Standards deemphasize formative reading in favor of close reading, post-reading analysis of literary elements. A counter-movement, with its own network of publications and workshops, emphasizes formative reading, emotional engagement, and the cultivation of adult reading habits. More grounded in reader-response theory, this approach promotes the emotional engagement and autonomy of student readers, and often makes use of young adult literature. This counter-movement, however, depends upon unspoken pre-conditions that connect it to some ancient regimes of formative reading.

AbstractA large amount of research on Convolutional Neural Networks (CNN) has focused on flat Classification in the multi-class domain. In the real world, many problems are naturally expressed as hierarchical classification problems, in which the classes to be predicted are organized in a hierarchy of classes. In this paper, we propose a new architecture for hierarchical classification, introducing a stack of deep linear layers using cross-entropy loss functions combined to a center loss function. The proposed architecture can extend any neural network model and simultaneously optimizes loss functions to discover local hierarchical class relationships and a loss function to discover global information from the whole class hierarchy while penalizing class hierarchy violations. We experimentally show that our hierarchical classifier presents advantages to the traditional classification approaches finding application in computer vision tasks. The same approach can also be applied to some CNN for text classification.

AbstractThe original design of a software system is rarely prepared for every new requirement. Software systems should be updated frequently, which is usually accompanied by the decline in software modularity and quality. Although many approaches have been proposed to improve the quality of software, a majority of them are guided by metrics defined on the local properties of software. In this article, we propose to use a global metric borrowed from the network science to detect the moving method refactoring. First, our approach uses a bipartite network to represent classes, features (i.e., methods and fields), and their dependencies. Second, a new metric is introduced to quantify the modularity of a software system as a whole. Finally, a crossover-only evolutionary algorithm that uses the metric as its fitness function is introduced to optimize the class structure of a software system and detect the methods that should be moved. Empirical results on the benchmark Java projects show that our approach can find meaningful methods that should be moved with a high stability. The advantages of our approach are illustrated in comparison with some other approaches, specifically one refactoring approach, namely search-based refactoring approach (SBRA), and two community detection algorithms, namely a graph theoretic clustering algorithm (MCODE) and a fast algorithm for community detection (FG). Our approach provides a new way to do refactoring from the perspective of software structure.

Few research studies within the field of mathematics education have focused on the ability to recognize quantities quickly and accurately without counting (i.e. subitizing). The aim of this research was to empirically explore the role of conceptual subitizing activities for enhancing preschool class children’s learning of the part-part- whole relations of number. 24 children (aged 6-7) and two teachers participated in the intervention. Due to ethical issues, data were only collected from 18 of the children. The design was a collaborative and iterative intervention, employing a mixed-method approach. Data consisted of pre-and post-test, teacher observation notes and teacher responses to questions about the children’s learning. Both the quantitative and qualitative analysis showed that conceptual subitizing activities supported children’s knowledge development regarding part-part-whole relations of number. At the group level, the children´s results between pre-and post-test showed an increase of 18.1 percent units and more than half of the children showed conceptual subitizing abilities in a qualitatively more developed way after having participated in the intervention. The result indicated that conceptual subitizing activities might enhance preschool class children’s understanding of the part-part-whole relations of number. The results however also elucidated that not all children improved their understanding of the part-part -whole relations of number. Future research should therefore consider individual differences when developing and carrying out interventions.

The population for this research is the whole students in X MIA MAN 1 Pati which is divided into 5 classes, while the sample taken for this research was X MIA 1 and X MIA 4 selected by using purposive sampling technique. The result of this study showed that 86.96% of students in experimental class achieved score > 75 and there was a difference of mean in the posttest for experimental class and control class i.e conseutively 85 and 75.19. The result of t-test showed tcount 0.000<0.05 which means there is a signifficant difference between control and experimental class. It also achieved N-Gain > 0.3 with the mean by 0.54. For the class control, 65.38% of students accomplished > 75 and N-Gain 0.14. Based on the research result, it can be inferred that guided-inquiry learning with JAS approach is effective to improve students’ learning result for the subject material of environmental pollution.

In several remote sensing applications, detecting exceptional/irregular regions (i.e, pixels) with respect to the whole dataset homogeneity is regarded as a very interested issue. Currently, this is limited to the pre-processing step aiming to eliminate the cloud or noisy pixels. In this paper, we propose to extend the coverage area and to tackle this issue by regarding the irregular/exceptional pixels as outliers. The main purpose is the adaptation of the class outlier mining concept in order to find abnormal and irregular pixels in hyperspectral images. This should be done taking into account the class labels and the relative uncertainty of collected data. To reach this goal, the Class Outliers: DistanceBased (CODB) algorithm is enhanced to take into account the multivariate high-dimensional data and the concomitant partially available knowledge of our data. This is mainly done by using belief theory and a learnable task-specific similarity measure. To validate our approach, we apply it for vegetation inspection and normality monitoring. For experimental purposes, the Airborne Prism Experiment (APEX) data, set acquired during an APEX flight campaign in June 2011, was used. Moreover, a collection of simulated hyperspectral images and spectral indices, providing a quantitative indicator of vegetation health, were generated for this purpose. The encouraging obtained results can be used to monitor areas where vegetation may be stressed, as a proxy to detect potential drought.

Authors name disambiguation (AND) is a complex problem in the process of identifying an author in a digital library (DL). The AND data classification process is very much determined by the grouping process and data processing techniques before entering the classifier algorithm. In general, the data pre-processing technique used is pairwise and similarity to do author matching. In a large enough data set scale, the pairwise technique used in this study is to do a combination of each attribute in the AND dataset and by defining a binary class for each author matching combination, where the unequal author is given a value of 0 and the same author is given a value of 1. The technique produces very high imbalance data where class 0 becomes 98.9% of the amount of data compared to 1.1% of class 1. The results bring up an analysis in which class 1 can be considered and processed as data anomaly of the whole data. Therefore, anomaly detection is the method chosen in this study using the Isolation Forest algorithm as its classifier. The results obtained are very satisfying in terms of accuracy which can reach 99.5%.

The method of synthesis for a wide class of nonlinear systems affine in control is considered. The proposed approach is based on the solution of a special optimal control problem. The integrand of the optimized functional is chosen in such a way that the Bellman equation has a desired solution. The nonlinear system design is reduced to the examination of the integrand of the optimized functional. To extend the domain of asymptotic stability of the nonlinear system, a sequence of the Lyapunov functions is used. The whole system becomes a system with variable structure.

The research findings describe a model of experiential learning that promotes the development of foundation phase student teachers’ metacognitive abilities for mathematics through classroom reflective discourse using an open approach. A case study was carried out on two foundation phase mathematics classes in South Africa’s universities; data were collected through observation and focus group interviews. The research’s main findings indicated that student teachers’ interest in reflective classroom discourse is important using an open-approach-based mathematics class, which helped pave the way for the student teachers to exhibit metacognitive abilities relevant to the teaching and learning steps of a foundation phase mathematics class. Deciding on the type of problem to work on, posing open-ended problems to colleagues for discussion in class, stimulating students’ reflective self-centred learning, whole-class discussion, comparison of a particular problem and summarising important information for self-development in teaching and learning through connecting students’ mathematical ideas all formed part of reflective classroom discourse. Recommendations were made for further development of metacognitive abilities. Keywords: mathematics class, metacognitive strategies, open approach, preservice teachers, reflective classroom, school learners, student teachers.

Full textAbstract:
Cyber-physical systems have emerged as a new engineering paradigm, which combine the cyber and physical world with comprehensive computational and analytical tools to solve complex tasks. In cyber-physical systems, components are developed to detect failures, prevent failures, or mitigate the failures of a system. Sensors gather real-time data as an input to the system for further processing. Therefore, the whole cyber-physical system depends on sensors to accomplish their tasks and the failure of one sensor may lead to the failure of the whole system. To address this issue, we present an approach that utilizes the Failure Modes, Effects, and Criticality Analysis, which is a prominent hazard analysis technique to increase the understanding of risk and failure prevention. In our approach, we transform the Failure Modes, Effects, and Criticality Analysis model into a UML(Unified Modeling Language) class diagram, and then a knowledge base is constructed based on the derived UML class diagram. Finally, the UML class diagram is used to build an ontology. The proposed approach employs a 5C architecture for smart industries for its systematic application. Lastly, we use a smart home case study to validate our approach.

Full textAbstract:
A new approach to solving the distributed control problem for a class of discrete-time nonlinear systems via a wireless neural control network (WNCN) is presented in this paper. A unified Lurie-type model termed delayed standard neural network model (DSNNM) is used to describe these nonlinear systems. We assume that all neuron nodes in WNCN which have limited energy, storage space, and computing ability can be regarded as a subcontroller, then the whole WNCN is characterized by a mesh-like structure with partially connected neurons distributed over a wide geographical area, which can be considered as a fully distributed nonlinear output feedback dynamic controller. The unreliable wireless communication links within WNCN are modeled by fading channels. Based on the Lyapunov functional and the S-procedure, the WNCN is solved and configured for the DSNNM to absolutely stabilize the whole closed-loop system in the sense of mean square with aH∞disturbance attenuation index using LMI approach. A numerical example shows the effectiveness of the proposed design approaches.

Integrating curriculum-based service learning program into chemistry courses yields many benefits for the students such as improved cognition and practical skills. Additionally the community partner benefits from both the expertise and the services of the class. This paper describes the success story of one such program conducted by students at Madras Christian College. It involves the interaction with informal recyclers and the chemical recycling of polyethylene terephthalate (PET) waste. The stakeholders of the project were the students, informal recyclers, residential population, and an NGO. The marginalized informal recyclers were brought into mainstream society through formal solid waste collection system. This approach views the recyclers as catalysts to tackle climate change instead of viewing them as a social burden. The public was taught waste segregation and collection methods. On the whole the program resulted in improving the immediate environment and saving a wetland where dumping of waste was carried out.

Full textAbstract:
In this paper, we will consider a cosmological model with two topological transitions of the space. The smooth 4-dimensional spacetime of the model admits topological transitions of its 3-dimensional slices. The whole approach is inspired by a class of exotic smoothness structures on [Formula: see text]. In particular, this class of smoothness structures induces two topological transitions. Then, we are able to calculate the energy scales as associated to these topological transitions. For the first transition we will get the value of the GUT scale and the energy of the second transition is at the electroweak scale. The topology of the exotic [Formula: see text] determines both, the energy of the scales by certain topological invariants, and the existence of the right-handed sterile neutrino. It is the input for the seesaw mechanism. Secondly, based on this model, we are able to calculate the neutrino masses which are in a very good agreement with experiments. Finally, we will speculate, again based on topology, why there are three generations of neutrinos and an asymmetry between neutrinos and anti-neutrinos.

The demand of renewable energy has increased the interest in whole-tree harvesting. The sustainability of whole-tree harvesting after clear-cutting, from an acidification point of view, depends on two factors: the present acidification status and the further loss of buffering capacity at harvesting. The aims of this study were to investigate the relationship between these two factors at 26 sites along an acidification gradient in Sweden, to divide the sites into risk classes, and to examine the geographical distribution of them in order to provide policy-relevant insights. The present status was represented by the acid neutralizing capacity (ANC) in soil solution, and the loss of buffering capacity was represented by the estimated exceedance of critical biomass harvesting (CBH). The sites were divided into three risk classes combining ANC and exceedance of CBH. ANC and exceedance of CBH were negatively correlated, and most sites had either ANC < 0 and exceedance (high risk) or ANC > 0 and no exceedance (low risk). There was a geographical pattern, with the high risk class concentrated to southern Sweden, which was mainly explained by higher historical sulfur deposition and site productivity in the south. The risk classes can be used in the formulation of policies on whole-tree harvesting and wood ash recycling.

This paper considers a class of non-homogeneous fractional systems with harmonic terms by means of the Riemann–Liouville definition. Two different approaches are applied to obtain the dual solution of the studied class. The first approach uses the Laplace transform (LT) and the solution is given in terms of the Mittag-Leffler functions. The second approach avoids the LT and expresses the solution in terms of exponential and periodic functions which is analytic in the whole domain. The current methods determine the solution directly and efficiently. The results are applicable for other problems of higher order.

In this paper we propose a high-level approach to developing GPU applications based on the Vulkan API. The purpose of the work is to reduce the complexity of developing and debugging applications that implement complex algorithms on the GPU using Vulkan. The proposed approach uses the technology of code generation by translating a C++ program into an optimized implementation in Vulkan, which includes automatic shader generation, resource binding, and the use of synchronization mechanisms (Vulkan barriers). The proposed solution is not a general-purpose programming technology, but specializes in specific tasks. At the same time, it has extensibility, which allows to adapt the solution to new problems. For single input C++ program, we can generate several implementations for different cases (via translator options) or different hardware. For example, a call to virtual functions can be implemented either through a switch construct in a kernel, or through sorting threads and an indirect dispatching via different kernels, or through the so-called callable shaders in Vulkan. Instead of creating a universal programming technology for building various software systems, we offer an extensible technology that can be customized for a specific class of applications. Unlike, for example, Halide, we do not use a domain-specific language, and the necessary knowledge is extracted from ordinary C++ code. Therefore, we do not extend with any new language constructs or directives and the input source code is assumed to be normal C++ source code (albeit with some restrictions) that can be compiled by any C++ compiler. We use pattern matching to find specific patterns (or patterns) in C++ code and convert them to GPU efficient code using Vulkan. Pattern are expressed through classes, member functions, and the relationship between them. Thus, the proposed technology makes it possible to ensure a cross-platform solution by generating different implementations of the same algorithm for different GPUs. At the same time, due to this, it allows you to provide access to specific hardware functionality required in computer graphics applications. Patterns are divided into architectural and algorithmic. The architectural pattern defines the domain and behavior of the translator as a whole (for example, image processing, ray tracing, neural networks, computational fluid dynamics and etc.). Algorithmic pattern express knowledge of data flow and control and define a narrower class of algorithms that can be efficiently implemented in hardware. Algorithmic patterns can occur within architectural patterns. For example, parallel reduction, compaction (parallel append), sorting, prefix sum, histogram calculation, map-reduce, etc. The proposed generator works on the principle of code morphing. The essence of this approach is that, having a certain class in the program and transformation rules, one can automatically generate another class with the desired properties (for example, the implementation of the algorithm on the GPU). The generated class inherits from the input class and thus has access to all data and functions of the input class. Overriding virtual functions in generated class helps user to carefully connect generated code to the other Vulkan code written by hand. Shaders can be generated in two variants: OpenCL shaders for google “clspv” compiler and GLSL shaders for an arbitrary GLSL compiler. Clspv variant is better for code which intensively uses pointers and the GLSL generator is better if specific HW features are used (like hardware ray tracing acceleration). We have demonstrated our technology on several examples related to image processing and ray tracing on which we get 30-100 times acceleration over multithreaded CPU implementation.

Microscopic tissue analysis is the key diagnostic method needed for disease identification and choosing the best treatment regimen. According to the Global Cancer Observatory, approximately two million people are diagnosed with colorectal cancer each year, and an accurate diagnosis requires a significant amount of time and a highly qualified pathologist to decrease the high mortality rate. Recent development of artificial intelligence technologies and scanning microscopy introduced digital pathology into the field of cancer diagnosis by means of the whole-slide image (WSI). In this work, we applied deep learning methods to diagnose six types of colon mucosal lesions using convolutional neural networks (CNNs). As a result, an algorithm for the automatic segmentation of WSIs of colon biopsies was developed, implementing pre-trained, deep convolutional neural networks of the ResNet and EfficientNet architectures. We compared the classical method and one-cycle policy for CNN training and applied both multi-class and multi-label approaches to solve the classification problem. The multi-label approach was superior because some WSI patches may belong to several classes at once or to none of them. Using the standard one-vs-rest approach, we trained multiple binary classifiers. They achieved the receiver operator curve AUC in the range of 0.80–0.96. Other metrics were also calculated, such as accuracy, precision, sensitivity, specificity, negative predictive value, and F1-score. Obtained CNNs can support human pathologists in the diagnostic process and can be extended to other cancers after adding a sufficient amount of labeled data.

Abstract It is now generally accepted that there are four learning modalities. Auditory learners learn best by listening so lecturing would be the way they would prefer to learn. Visual learners are those who prefer the printed word. They would learn best by reading or responding to the use of an overhead projector type of teaching. Tactile learners learn best by manipulating objects so they would prefer laboratory exercises. Kinesthetic (also known as whole body learners) prefer to learn through physical activities. This is the group of learners who would benefit most by this type of role-playing workshop. There are three basic modalities to process information to memory: visual (learning by seeing), auditory (learning by hearing), and kinesthetic (learning by doing). We tested role-playing modality at College of Pharmacy Chicago State University. This was done during spring semester where pharmacy year 1 students were taking Immunology as a didactic course. The students were divided into different small learning groups of 7–10 students in a class of 90 students and were made to role-play different types of hypersensitivity reactions. The role-playing acts were acted up in front of the whole class and also recorded. Asking Likert-type ordinary scale data analysis questions assessed the effectiveness of this modality and student learning. A statistically significant number of students found this immunology role-playing exercise as a fun and very beneficial activity. Students strongly agreed that this group-base role-playing approach was very powerful in conceptual understanding of hypersensitivity reactions, which is a clinically important and significant immunology topic.

Summary The spread of drug resistance amongst clinically-important bacteria is a serious, and growing, problem [1]. However, the analysis of entire genomes requires considerable computational effort, usually including the assembly of the genome and subsequent identification of genes known to be important in pathology. An alternative approach is to use computational algorithms to identify genomic differences between pathogenic and non-pathogenic bacteria, even without knowing the biological meaning of those differences. To overcome this problem, a range of techniques for dimensionality reduction have been developed. One such approach is known as latent-variable models [2]. In latent-variable models dimensionality reduction is achieved by representing a high-dimensional data by a few hidden or latent variables, which are not directly observed but inferred from the observed variables present in the model. Probabilistic Latent Semantic Indexing (PLSA) is an extention of LSA [3]. PLSA is based on a mixture decomposition derived from a latent class model. The main objective of the algorithm, as in LSA, is to represent high-dimensional co-occurrence information in a lower-dimensional way in order to discover the hidden semantic structure of the data using a probabilistic framework. In this work we applied the PLSA approach to analyse the common genomic features in methicillin resistant Staphylococcus aureus, using tokens derived from amino acid sequences rather than DNA. We characterised genome-scale amino acid sequences in terms of their components, and then investigated the relationships between genomes and tokens and the phenotypes they generated. As a control we used the non-pathogenic model Gram-positive bacterium Bacillus subtilis.

We study the uniform asymptotics of a system of polynomials orthogonal on [-1, 1] with weight function w(x) = exp {-1/(1 - x2)μ}, 0 < μ < 1/2, via the Riemann–Hilbert approach. These polynomials belong to the Szegö class. In some earlier literature involving Szegö class weights, Bessel-type parametrices at the endpoints ±1 are used to study the uniform large degree asymptotics. Yet in the present investigation, we show that the original endpoints ±1 of the orthogonal interval are to be shifted to the MRS numbers ±βn, depending on the polynomial degree n and serving as turning points. The parametrices at ±βn are constructed in shrinking neighborhoods of size 1 - βn, in terms of the Airy function. The polynomials exhibit a singular behavior as compared with the classical orthogonal polynomials, in aspects such as the location of the extreme zeros, and the approximation away from the orthogonal interval. The singular behavior resembles that of the typical non-Szegö class polynomials, cf. the Pollaczek polynomials. Asymptotic approximations are obtained in overlapping regions which cover the whole complex plane. Several large-n asymptotic formulas for πn(1), i.e. the value of the nth monic polynomial at 1, and for the leading and recurrence coefficients, are also derived.

This paper addresses the fuzzy control problem using the Lyapunov synthesis approach. In order to deal with cases where the system state is unavailable, a state observer is proposed. Consequently, the whole system behavior can be attributed to a kind of standard singularly perturbed form. At the same time, to deal with the gap, if any, between the real state and its estimated value from the state observer, we view it as a part of system disturbance, and propose a unique way to deal with the disturbance, i.e., adopt a switching function with an alterable coefficient, which is tuned by adaptive law based on the tracking error between the output of the considered system and the desired value. Finally, it is shown that the fuzzy controller proposed guarantees the tracking error will shrink to zero, while maintaining the stability of all signals involved in the system.

Aims:This systematic analysis aims to address the research question – do whole-school nurturing approaches show any impact in the short or long term on (1) emotional/behavioural, (2) cognitive/educational or (3) teacher/school variables?Rationale:Trauma or Adverse Childhood Experiences can have long-term consequences though causing problems in attachment, which nurturing approaches seek to ameliorate. Whilst there is a good deal of international research evidence on the impact of Nurture Groups in schools, less is known about the impact of whole school nurturing approaches on pupils and schools. This paper aims to address that gap.Findings:A total of 146 papers were retrieved from four databases and 13 from other sources. After excluding 61 duplicate papers, 98 papers were screened in relation to inclusion and exclusion criteria, and only 13 papers were finally selected. Results suggest that nurturing approaches can have a positive impact on pupils’ social, emotional and behavioural needs, academic progress, other pupils in the mainstream class/school, parents and home life, and the whole school. Additionally, the length of time a nurturing approach is in place in a school contributes to its effectiveness.Limitations:Limitations include the quality of research available, lack of papers focusing on universal whole-school nurturing approaches and lack of international studies.Conclusions:The paper highlights the need for more robust research focusing on universal whole-school nurturing approaches to be carried out.

Full textAbstract:
A novel fuzzy adaptive regulation approach is proposed for a class of output-feedback nonlinear systems based on dynamic surface control (DSC). The whole system is needed only one fuzzy approximator, and therefore only one approximator error and one unknown fuzzy parameter vector need to be tackled adaptively, so that the whole controller structure is more simpli ed than the existing result. It is proved that the proposed design approach is able to guarantee semi-global uniform ultimate boundedness (SGUUB) of all signals in the closed-loop system, with arbitrary small error by appropriately choosing design constants.
