The scientific aim of the article is to present the characteristics of an old text: Prawo dziecka do szacunku [A Child’s Right to Respect] by Janusz Korczak. The method adopted for the article is a semantic and structural analysis of the pedagogical book, in which the educator presented issues regarding key concepts of pedagogy, such as education, upbringing, and care. The pedagogy book under analysis does not fit into the contemporary framework of scientific language, but it still brings up-to-date findings on pedagogical practice. Janusz Korczak’s pedagogical texts should be obligatorily included in the reading canon of theoreticians and practitioners of education.

The core–periphery structure is one of the key concepts in the structural analysis of complex networks. It consists of a partitioning of the node set of a given graph or network into two groups, called core and periphery, where the core nodes induce a well-connected subgraph and share connections with peripheral nodes, while the peripheral nodes are loosely connected to the core nodes and other peripheral nodes. We propose a polynomial-time algorithm to detect core–periphery structures in networks having a symmetric adjacency matrix. The core set is defined as the solution of a combinatorial optimization problem, which has a pleasant symmetry with respect to graph complementation. We provide a complete description of the optimal solutions to that problem and an exact and efficient algorithm to compute them. The proposed approach is extended to networks with loops and oriented edges. Numerical simulations are carried out on both synthetic and real-world networks to demonstrate the effectiveness and practicability of the proposed algorithm.

The article identifies several key concepts used to describe and categorize social pedagogy. The first section of the paper establishes a framework for considering the diversity that characterizes the field, including reflection on social pedagogy’s theoretical, political and social dimensions. This is followed by a discussion based on a holistic understanding of the interaction between individuals and society, which leads to recognition of the profession’s tendency to present itself with a “Janus face.” The paper concludes by pointing out prospects for further development of social pedagogy in the dialectic between theory/research and pedagogical practice.

Piagetian Theory

Education has the function of transmitting to the students the systematized knowledge, the historically produced scientific knowledge that will instrumentalize them to act in society in a critical, concrete and conscious way. Over the years, society has undergone several changes, since it is dynamic and in constant movement, but the Brazilian educational system has not been able to keep up with the essential changes in the individual's formal education. In this sense, this article aims to present the contributions of the Piagetian theory in the educational area, seeking to clarify some misconceptions about this theory, to train and inform teachers about its use in pedagogical practice, since it allows a closer approximation of the school social role. For that, we use, as an epistemological theoretical contribution, authors who discuss the key concepts of Jean Piaget's constructivist theory. From these discussions, it is possible to confirm the relevance of Piagetian theory in the educational area, promoting knowledge and human development in all its possibilities.

Abstract The visual mode provides emergent bi/multilinguals an essential resource to construct scientific explanations. Yet, while a metalanguage is used to describe the written mode of scientific language such as, claim, evidence, reason; there is little research that makes students aware of the metalanguage of a visual mode. We propose an introduction to the visual metalanguage will ensure emergent bi/multilinguals better access to the visual mode. This study employs an instrumental case study to examine the introduction of visual metalanguage to a fifth-grade science class. Two cameras record ten emergent bi/multilinguals as they construct scientific explanations in nine lessons. We use a framework informed by social semiotics to analyse the meanings made. The data revealed that an awareness of the visual metalanguage led to an enhanced commitment to illustrate the explanation of the phenomenon, illuminated key concepts and provided more context to the audience. In addition, teacher questioning became more focused.

Spirillum serpens possesses a surface layer protein which exhibits a regular hexagonal packing of the morphological subunits. A morphological model of the structure of the protein has been proposed at a resolution of about 25 Å, in which the morphological unit might be described as having the appearance of a flared-out, hollow cylinder with six ÅspokesÅ at the flared end. In order to understand the detailed association of the macromolecules, it is necessary to do a high resolution structural analysis. Large, single layered arrays of the surface layer protein have been obtained for this purpose by means of extensive heating in high CaCl2, a procedure derived from that of Buckmire and Murray. Low dose, low temperature electron microscopy has been applied to the large arrays.As a first step, the samples were negatively stained with neutralized phosphotungstic acid, and the specimens were imaged at 40,000 magnification by use of a high resolution cold stage on a JE0L 100B. Low dose images were recorded with exposures of 7-9 electrons/Å2. The micrographs obtained (Fig. 1) were examined by use of optical diffraction (Fig. 2) to tell what areas were especially well ordered.

Low Ionic Strength

While DNA-dependent RNA polymerase represents one of the key enzymes involved in transcription and ultimately in gene expression in procaryotic and eucaryotic cells, little progress has been made towards elucidation of its 3-D structure at the molecular level over the past few years. This is mainly because to date no 3-D crystals suitable for X-ray diffraction analysis have been obtained with this rather large (MW ~500 kd) multi-subunit (α2ββ'ζ). As an alternative, we have been trying to form ordered arrays of RNA polymerase from E. coli suitable for structural analysis in the electron microscope combined with image processing. Here we report about helical polymers induced from holoenzyme (α2ββ'ζ) at low ionic strength with 5-7 mM MnCl2 (see Fig. 1a). The presence of the ζ-subunit (MW 86 kd) is required to form these polymers, since the core enzyme (α2ββ') does fail to assemble into such structures under these conditions.

Introduction: The analysis and interpretation of electron micrographs of cells and tissues, often requires the accurate extraction of structural networks, which either provide immediate 2D or 3D information, or from which the desired information can be inferred. The images of these structures contain lines and/or curves whose orientation, lengths, and intersections characterize the overall network.Some examples exist of studies that have been done in the analysis of networks of natural structures. In, Sebok and Roemer determine the complexity of nerve structures in an EM formed slide. Here the number of nodes that exist in the image describes how dense nerve fibers are in a particular region of the skin. Hildith proposes a network structural analysis algorithm for the automatic classification of chromosome spreads (type, relative size and orientation).

Ethnogeriatrics is an evolving specialty in geriatric care that focuses on the health and aging issues in the context of culture for older adults from diverse ethnic backgrounds. This article is an introduction to ethnogeriatrics for healthcare professionals including speech-language pathologists (SLPs). This article focuses on significant factors that contributed to the development of ethnogeriatrics, definitions of some key concepts in ethnogeriatrics, introduces cohort analysis as a teaching and clinical tool, and presents applications for speech-language pathology with recommendations for use of cohort analysis in practice, teaching, and research activities.
