Authors: Abeysuriya Hashini Imalsha , Bulugahapitiya Vajira P , Jayatissa Loku Pullukkutige
Published: August 2021

Sri Lanka is a habitat of diverse fruit varieties; nevertheless 95% of them are underutilized by people due to unawareness of their nutritional values and health aspects, and hence become ‘minor fruits’. This study was aimed on revealing vitamin C, iron and antioxidant contents of 29 varieties of minor fruits (MFs) with the comparison of the same with three best commonly consumable fruits (CFs), namely Carica papaya, Mangifera indica and Psidium guajava. Ascorbic acid (Asc), dehydroascorbic acid (DAsc), vitamin C (TC), phenolic (TP), flavonoid (TF), iron (Fe) contents and antioxidant capacities (AOCs) of fruits were determined using standard methods. The results of mean Asc, DAsc, TC, TP, TF and Fe contents in 100 gm of MFs ranged from 3.1 to 121.5 mg, 1.2 to 70.7 mg, 6.6 to 136.1 mg, 24.9 to 1613.3 mg Gallic acid equivalent, 6.2 to 228.0 mg Quercetin equivalents and 0.2 to 4.9 mg respectively. DPPH and Ferric Reducing Antioxidant Power (FRAP) assays were used for AOCs and variation of IC50 values in a DPPH assay was 1.2 to 245.4 mg/ml whereas FRAP values ranged from 9.6 to 486.7 ?mol FeSO4/gm. Among the studied minor fruits, Melastoma malabathricum (Maha bovitiya/ Malabar melastome) is found as the best respect to all considered parameters. As a conclusion, it can be stated that, the Sri Lankan minor fruits are good alternatives to the common fruits as they are recognized as good source of vitamin C, iron and higher content of antioxidants. As an outcome, Sri Lankan minor fruits can be promoted as alternatives to common fruits and as source of revenue for national economy.

Published: August 2021

Background

There is the need to encourage physical activity (PA) among adolescents with overweight or obesity.

Objectives

The present study aimed to assess the relationship between health-related physical fitness (PF) and nutritional status, and to identify those activities more suited to adolescents with excess weight.

Methods

This cross-sectional study included 3,062 in-school adolescents, aged 10–18 years. We collected information on sex, age, weight, height, skinfold thickness, trunk height and leg length, and calculated body mass index (BMI) z-score, fat mass percentage, and peak height velocity (PHV). Participants were tested for PF by the 20-m shuttle run test (cardiorespiratory fitness); medicine ball throw and standing long jump tests (musculoskeletal fitness) and sit and reach test (flexibility). We used generalized linear mixed models (GLMM) to analyze the relationship between nutritional status and performance in the fitness tests, controlled for maturity offset and fat mass percentage.

Results

1,563 (51%) were boys, mean age 12.6 years (±1.8), 22.8% were overweight and 12.5% had obesity. In both sexes, adolescents with obesity did better in the upper body strength test than their eutrophic peers. Boys with obesity had worse cardiorespiratory fitness and lower body muscular strength than eutrophic boys. Girls with obesity had similar cardiorespiratory fitness and better lower body strength than eutrophic girls.

Conclusion

In muscular strength fitness tests, adolescents with obesity performed similarly to, or better than, their eutrophic peers. Motivation to maintain regular PA is reinforced by positive experiences. Interventions that emphasize muscular strength PF should be developed for adolescents with obesity.
Advanced data handling architecture for earth observation satellites
Authors: Bozler Julian , Herpel Hans Juergen , Johansson Jan , Gasti Wahida , Mourra Olivier
Published: August 2021

In this paper we describe how commercial open standards for embedded systems could affect the architecture of future satellite data handling systems. Traditionally, satellite data handling systems are based on the principles of a federated architecture, i. e. one function is implemented as one box. Each box has its own housing and power supply. In the paper we describe the transition path from the traditional federated architecture to a centralized but modular architecture based on adapted industrial standards. In the presented approach functional modules like on-board computer, Global Navigation Satellite System receiver, interface boards, etc. are combined in a rack communicating via a standard backplane using standardized communication links. The analysis performed during the Advanced Data Handling Architecture study showed that this approach contributes significantly to mass and power reduction (approx. 20 %) of a typical satellite data handling system. Another major point highlighted in the Advanced Data Handling Architecture study is the simplification of Assembly, Integration and Test activities. All this will help space industry to handle increasing system complexity while keeping costs at an acceptable level.
Characterization of polymeric biomedical balloon: physical and mechanical properties
Authors: Sadeghi Farhad , Le David
Published: August 2021

Tubes from nylon 12 and Pebax 6333 resins were produced using an extrusion process. The extruded tubes were used to produce balloons for angioplasty applications. The tubes were stretched using blow molding process to produce balloons. Melt rheology behavior for nylon 12 and Pebax were studied and nylon 12 showed a more pronounced shear thinning behavior compared to Pebax. Orientations of the tubes and the balloons were assessed using Fourier transform infrared spectroscopy (FTIR) and it was found that nylon material is more sensitive to molecular orientation when stretched compared to Pebax material. Melting behavior for the tubes and balloons were investigated using dynamic scanning calorimetry (DSC). The melting temperature shifted to higher temperatures when the tubes are stretched into balloons and the shift was more pronounced for Pebax balloon than nylon. Morphology of Pebax balloon surface revealed a hybrid structure consisting of hard segments dispersed in soft segments and amorphous phases. The hard segments are crystallized polyamides that are biaxially oriented in the balloon with higher molecular orientation in the radial direction compared to axial direction. This resulted in a higher tensile strength along the radial direction compared to axial for the balloons. Dynamic mechanical analyzer (DMA) tests showed that the glass transition temperature of the nylon tubes shifted to higher temperatures (from 51 to 82 °C) during the balloon forming process, which means the nylon becomes stiffer and less flexible when formed into a balloon.

Published: August 2021

Axon regenerative failure in the mature CNS contributes to functional deficits following many traumatic injuries, ischemic injuries, and neurodegenerative diseases. The complement cascade of the innate immune system responds to pathogen threat through inflammatory cell activation, pathogen opsonization, and pathogen lysis, and complement is also involved in CNS development, neuroplasticity, injury, and disease. Here, we investigated the involvement of the classical complement cascade and microglia/monocytes in CNS repair using the mouse optic nerve injury (ONI) model, in which axons arising from retinal ganglion cells (RGCs) are disrupted. We report that central complement C3 protein and mRNA, classical complement C1q protein and mRNA, and microglia/monocyte phagocytic complement receptor CR3 all increase in response to ONI, especially within the optic nerve itself. Importantly, genetic deletion ofC1q,C3, orCR3attenuates RGC axon regeneration induced by several distinct methods, with minimal effects on RGC survival. Local injections of C1q function-blocking antibody revealed that complement acts primarily within the optic nerve, not retina, to support regeneration. Moreover, C1q opsonizes and CR3+microglia/monocytes phagocytose growth-inhibitory myelin debris after ONI, a likely mechanism through which complement and myeloid cells support axon regeneration. Collectively, these results indicate that local optic nerve complement-myeloid phagocytic signaling is required for CNS axon regrowth, emphasizing the axonal compartment and highlighting a beneficial neuroimmune role for complement and microglia/monocytes in CNS repair.

SIGNIFICANCE STATEMENTDespite the importance of achieving axon regeneration after CNS injury and the inevitability of inflammation after such injury, the contributions of complement and microglia to CNS axon regeneration are largely unknown. Whereas inflammation is commonly thought to exacerbate the effects of CNS injury, we find that complement proteins C1q and C3 and microglia/monocyte phagocytic complement receptor CR3 are each required for retinal ganglion cell axon regeneration through the injured mouse optic nerve. Also, whereas studies of optic nerve regeneration generally focus on the retina, we show that the regeneration-relevant role of complement and microglia/monocytes likely involves myelin phagocytosis within the optic nerve. Thus, our results point to the importance of the innate immune response for CNS repair.

Published: August 2021

Background

Gender dysphoria could be associated with low socioeconomic status (SES). SES could be modified by age, ethnic background, and medical morbidity.

Aim

To determine SES in a national study population including transgender persons in Denmark.

Methods

National register-based cohort study in Danish transgender persons and age-matched controls. The transgender study cohort included persons with ICD-10 diagnosis code of 'gender identity disorder' and/or persons with legal sex change and persons who fulfiled the inclusion criteria during 2000–2018. The main outcome measure was SES including personal income, occupational status, and education.

Results

The cohort included 2770 transgender persons and 27,700 controls. In the transgender study cohort, 1437 were assigned male at birth (AMAB), median age (interquartile range, IQR) 26.0 (17.3) years, and 1333 were assigned female at birth (AFAB), median age 22.5 (10.3) years. Adjusting for age and sex, the relative risk ratio (RRR) of low vs high personal income was 5.6 (95% CI: 4.9; 6.3) in transgender persons compared to controls. The RRR of low vs high income was 6.9 (5.8; 8.3) in persons AMAB compared to control males and 4.7 (3.9; 5.6) in persons AFAB compared to control females. The RRR of low vs high income was 3.7 (3.2; 4.3) in transgender persons of Danish origin compared to controls. The Charlson comorbidity index was comparable in transgender persons vs controls.

Conclusions

Being transgender was negatively associated with SES. In transgender persons, the risk of low vs high income could be more pronounced in transgender persons of foreign origin.

An Arranged Marriage: Police - Media Conflict & Collaboration
Authors: Chrismas Robert
Published: August 2021

Media and police professionals are bound together in interdependent, and often tense, working relationships. For different purposes both professions need to work effectively together while simultaneously retaining independence from each other. These complex inter-reliant relationships create unique challenges that often call for improvement. This essay examines whether relationships between interdependent professional organizations can be improved through a collaborative problem-solving intervention, based  on the interactive methods of facilitated dialogue and appreciative inquiry. The article describes a case study of a large Canadian police agency working with local media outlets to improve their working relationship. It highlights the importance of conflict analysis followed by effective change management strategies in implementation of collaborative solutions that meet everyone’s needs. This case study illustrates dynamics that generalize to organizations that have strong organizational cultures and are highly independent and simultaneously required to work together. Some examples of such organizations are military, prison guards, scholars, medical professionals, social workers, teachers, lawyers and most government agenciesLes médias et les corps policiers sont à la fois interreliés et interdépendants, et leur collaboration est souvent tendue. Dans divers objectifs, ils doivent travailler efficacement ensemble tout en maintenant leur propre autonomie. Ces relations complexes donnent lieu à des difficultés auxquelles il faut remédier. Cet essai porte sur les améliorations pouvant être apportées dans les relations entre deux organisations professionnelles interdépendants par l’entremise d’une intervention visant à résoudre les problèmes fondée sur des méthodes interactives de facilitation du dialogue et d’interrogation appréciative. Cet article décrit un cas où une grande agence policière canadienne a collaboré avec des médias locaux en vue d’améliorer leur relation de travail. On y souligne l’importance de l’analyse des conflits suivie de stratégies efficaces de gestion du changement dans la mise en œuvre de solutions axées sur la collaboration et répondant aux besoins de tous. Cette étude présente les dynamiques communes aux organismes indépendants dont la culture d’entreprise est bien affirmée, et devant travailler en partenariat. Parmi ces organisations, on compte l’armée, les gardes de prison, le secteur universitaire, le corps médical, les travailleurs sociaux, les enseignants, les avocats et la plupart des organismes gouvernementaux.
Equity, pedagogy and inclusion. Harnessing digital technologies to support higher education access and success
Authors: Elliott Alison
Published: August 2021

Australia is striving to reach a 20 per cent across-the-board higher education target participation rate for students from low socio-economic backgrounds by 2020. This paper focuses on enabling higher education access for students who might otherwise be excluded by complex socio-economic circumstances. Digital learning and communication tools provide a vital pathway to higher education and a means of re-engineering pedagogies to better meet students’ learning needs, especially when students cannot access regular on campus face-to-face teaching. On-line learning enables both access to higher education  and effective ways of engaging students with learning, especially those who are isolated by location or by circumstances associated with work and family commitments. This paper focuses on broad-brush factors students say supported their study success while undertaking an externally delivered, on-line teaching degree. It reports on students’ decision to study and their subsequent on-line study experiences, progression and outcomes. Analyses of students’ perceptions indicated the value of on-line pedagogy supported by ‘face-to-face’ interaction (albeit at a distance) with academics. While students wanted to study externally and on-line and in their ‘own time’ and at their own ‘pace’, all valued a personal, on-going relationship with their lecturer, teacher or other university-based mentor. Overwhelmingly, students , found the on-line learning relatively straightforward to navigate, practical and rewarding, but all wanted conversations with a “real person” although this could be on the phone, in a video conference/Skype situation or as part of a remote site ‘tutorial’ or consultation.
Community-based learning: A model for higher education and community partnerships
Authors: Day Peter
Published: August 2021

This paper presents a model of community-based learning partnerships, developed at the University of Brighton, for consideration by Higher Education as a means to securing effective community informatics engagement.  The absence of funding and time to pursue research proposals required me to be creative in continuing collaboration with our community partners of funded research projects. It is suggested here that the academic curriculum together with the resources and goodwill of a UK university can support both the formal requirements of HE student learning and the more informal learning needs of community practice through the development of community media/informatics learning partnerships. This is the first in a series of papers to be written that share the story of community-based learning experiences at the University of Brighton. Our purpose is to engage in meaningful community Informatics/media research and practice partnerships with a view to contributing to knowledge whilst affecting social change. A number of preliminary community informatics/media partnership activities are introduced through the joint lenses of community empowerment and community development. The significance of community voice and community learning in facilitating and enabling active citizenship and empowered communities through community informatics practices is also explored.
DigiPopEd: Popular Education and Digital Culture
Authors: O'Reilly-Rowe Dan
Published: August 2021

The rise of digitisation has led to a radical rethinking of the way in which research and publishing contribute to education, particularly with regards to the previously distinct and now rather more unstable categories of knowledge production and consumption. This article explores aspects of the relationship between digital culture and social movements by examining the adoption of digital publishing tools by educators working in the popular education methodology. Using BuildTheWheel.org, an online community oriented towards the sharing of curriculum as a case study, it examines the apparent meshing of some of the principal components of digital culture as outlined by Mark Deuze, with the goals, values, and practices of popular education, and explores the re-imagining of power relations between teacher and student, author and audience, producer and consumer.

Published: August 2021

To prevent the illegal trade of precious wood in circulation, a wood species identification method based on convolutional neural network (CNN), namely PWoodIDNet (Precise Wood Specifications Identification) model, is proposed. In this paper, the PWoodIDNet model for the identification of rare tree species is constructed to reduce network parameters by decomposing convolutional kernel, prevent overfitting, enrich the diversity of features, and improve the performance of the model. The results showed that the PWoodIDNet model can effectively improve the generalization ability, the characterization ability of detail features, and the recognition accuracy, and effectively improve the classification of wood identification. PWoodIDNet was used to analyze the identification accuracy of microscopic images of 16 kinds of wood, and the identification accuracy reached 99%, which was higher than the identification accuracy of several existing classical convolutional neural network models. In addition, the PWoodIDNet model was analyzed to verify the feasibility and effectiveness of the PWoodIDNet model as a wood identification method, which can provide a new direction and technical solution for the field of wood identification.

Numeric Low-Altitude Altimeter Modeling with Computation of Additional Modulation Frequencies Using a Genetic Algorithm
Authors:   Volgograd State University, Zakharchenko Vladimir , Zakharchenko Sergey ,   Open Systems LLC
Published: August 2021

This study is concerned with the problem of increasing the accuracy of a low-altitude altimeter employing the frequency modulation principle. A way to suppress the “discrete error” of the altimeter by employing additional frequency modulation of the carrier wave and averaging the resulting counts is considered. The benefit of such approach is simplicity of technical implementation manifesting in minimal changes in the microwave path and the recording device, which needsto run in averaging count mode. This work presents a genetic algorithm for computing the array of additional modulation frequencies which can be used to reduce the mean square of the discrete error given a limited frequency band. Results of error calculations presented are obtained via mathematical modeling of the altimeter’s operation. It is shown that using additional modulation frequencies obtained by the genetic algorithm allows to reduce the average measurement error two times relatively to the linear modulation form without expanding the occupied frequency band.

Features of the Electronic Structure of Excited Quadrupolar Molecules in Non-Polar Solvents
Authors:   Volgograd State University, Siplivy Nickolay , Ivanov Anatoly ,   Volgograd State University
Published: August 2021

Interactions of the electronic subsystem of the quadrupolar fluorophore with intramolecular highfrequency antisymmetric vibrations and solvent polarization are responsible for charge transfer symmetry breaking (SB), which is observed after optical excitation of such molecules in polar solvents. It is known that although these two interactions are mathematically described in similar ways, only the interaction of the fluorophore with solvent orientational polarization can create a state with broken symmetry if this interaction is strong enough. Nevertheless, the interaction of a quadrupolar fluorophore with intramolecular highfrequency antisymmetric vibrations in nonpolar solvents leads to a considerable reconstruction of the electronic subsystem. The analysis of the excited state of quadrupolar molecules in nonpolar solvents performed in this study reveals that such molecules can behave like quantum twostate systems, that is, as a quasispin s = 1/2, having an electric dipole moment instead of a magnetic one. This feature of excited quadrupolar molecules may be of interest to emerging technologies of molecular electronics.

Published: August 2021

The purpose. In modern conditions, the task of improving systems for storing material stocks has significant scientific and practical significance. At the same time, the nature and degree of influence of the parameters of the incoming flow of goods on the required technical equipment of warehouses from the standpoint of logistics and a systematic approach have been insufficiently studied. The absence of a final solution to the problem of developing a universal methodology for determining rational technical and technological parameters of warehouses for packaged goods formulated the goal of the study, which is to determine the rational equipment of a warehouse complex on the basis of simulation modeling of the process of its functioning, formalized by a Petri net. Methodology. In the work, the authors present a methodology for formalizing the process of functioning of a transport and warehouse complex using a Petri net in the QPNet environment. The technique of technical and economic comparison of options for equipping a warehouse complex, which is based on the use of modified reduced costs, is presented. Results. The paper reviews the existing imitation models of warehouse complexes, identifies their advantages and disadvantages. On the basis of the analysis performed, a simulation system was determined for the development of a model of a warehouse complex. The article presents a universal method for determining the rational technical and technological parameters of warehouses for packaged goods using a simulation model of a warehouse, the technological process of which is represented by a Petri net. With the developed simulation model of the composition, a series of experiments were performed, differing in the operational conditions of operation, as a result of which a set of technical and operational indicators of the warehouse complex was obtained. The obtained indicators of the warehouse functioning became the basis for determining its rational technical equipment. The practical significance of the methodology presented in the work for constructing a universal model of a warehouse complex and a technical and economic assessment of the indicators of its functioning will make it possible to more accurately determine the rational number of technical means and technical equipment in the design of new or reconstruction of existing transport and warehouse complexes.

The conclusions are drawn on the possible benefit for large universities, on its consequences for competition in higher education, and on the partnership benefits for all market players.
A Light-Space-Time Quantum-Computational Model of Subtle-DNA & Genetics
Authors: Malik Pravir
Published: August 2021

Abstract— Subtle-DNA can be thought of as a conceptual-construct consisting of a double-helix structure, arranged as a light-based downwardstrand and a time-based upward-strand. Light imagined existing at different constant speeds far greater than the known speed of c – 186,000 miles per second - offers a unique view of quanta and quantum computation, and the precipitation of such light from higher to lower speeds offer insight into the conceptual downward-strand of subtle-DNA. Such a downward-strand structures an involutionary-reality that seeds space, and subsequently becomes the basis of an evolutionaryreality structured as a time-based upward-strand of subtle-DNA. Analyses of such a composite lightspace-time structure further provides a unique point of view into the origin and possibilities of genetics. Genetics can be seen as having a diverse light-based functional, as opposed to a solely form-based foundation. Genetics can also be perceived as being the output of a persistent quantum-level computation. Such a modeling provides useful hypotheses into the subtle conceptual structure of DNA, into the architecture of mutation and the likely processes of constructive and destructive mutation, and the mechanism of heredity. Further the relationship and possible impacts of the quantum-based processes of entanglement and superposition on genetics, and future possibilities due to practically infinite amount of information in antecedent layers of light can be constructed.

Nowadays the modern world depends on connections through the internet brings different teams together. The essential components of communication are sender, medium, and receiver. Data transmission over the internet is not possible without any encryption method due to security issues.
Different types of areas like corporate sectors, banking sectors, government sectors, and many other sectors share their data through the internet. Hackers always try to attack the transmitted data and try to recover the data. Various techniques are developed for providing data security. Cryptography
is used for the safe transmission of data. Encryption is done at the sender side in cryptography, and decryption is done at the receiver side. In the encryption technique, Caesar cipher is one of the best examples. The analysis of Basic Caesar cipher, Delta formation Caesar cipher, and XOR
Caesar cipher is done based on many parameters like Avalanche Effect, Frequency Test, and Brute force attack. The authors of this paper have tried to modify the caesar cipher method, which produces ciphertext that can be read. After that with the new ciphertext that can be read, then cryptanalysis
not suspicious of the ciphertext.

Published: August 2021

RESUMO O presente artigo teve como objetivo analisar como o esporte e os processos de educação do corpo se manifestaram nas crônicas de Paulo Barreto, mais conhecido como João do Rio. As fontes selecionadas foram as crônicas publicadas pelo literato até 1921, ano de sua morte, cujo assunto primário ou secundário tenha sido o esporte. A palavra se mostrou presente na obra do escritor, porém se manifestou de uma forma ampla, ora repercutindo pontos positivos ora enfatizando aspectos negativos, mas como característica comum as diversas maneiras de educação do corpo. A título de conclusão, aponta-se que o esporte foi acionado pelo autor para representar as facetas existentes no seio da sociedade carioca e que nessas representações estavam evidentes modos de vida que possuíam alguns elementos educacionais relativos ao corpo.
Feral dogs in Chitral gol national park, Pakistan: a potential threat to the future of threatened Kashmir Markhor (Capra falconeri cashmiriensis)

Abstract Feral dogs are well-organized hunters of ungulates in many parts of the world, causing great damage to wildlife populations and ultimately to the ecosystem. In Pakistan, the impacts of feral dogs on the wildlife have not been documented yet. In a period of fifteen years (2006-2020), feral dogs have killed hundreds of threatened markhor in Chitral gol national park (CGNP), Pakistan. Despite direct predation other impacts including disturbance and competition with other natural predators, could compromise conservation and management efforts. The population of feral dogs seems to have been increased with the increase of dumping sites by communities. Our findings suggest that there are pressing needs of controlling the feral dogs population and eradicating them from the core zone of CGNP and surrounding buffer communities. Conventional culling of dogs should be coupled with modern techniques like castration and sterilization. Communities should be educated regarding the clean environment, proper disposal of home wastes and, biodiversity conservation.

Abstract The intertidal rocky shores in continental Chile have high species diversity mainly in northern Chile (18-27° S), and one of the most widespread species is the gastropod Echinolittorina peruviana (Lamarck, 1822). The aim of the present study is do a first characterization of spatial distribution of E. peruviana in along rocky shore in Antofagasta town in northern Chile. Individuals were counted in nine different sites that also were determined their spectral properties using remote sensing techniques (LANDSAT ETM+). The results revealed that sites without marked human intervention have more abundant in comparison to sites located in the town, also in all studied sites was found an aggregated pattern, and in six of these sites were found a negative binomial distribution. The low density related to sites with human intervention is supported when spectral properties for sites were included. These results would agree with other similar results for rocky shore in northern and southern Chile.
Pensar o corpo oprimido d’A Gorda, de Isabela Figueiredo*
Authors: Uechi Fabrizio
Published: August 2021

Resumo Neste artigo, eu proponho uma tradução do romance A gorda, escrito por Isabela Figueiredo. Se a literatura não é um lugar essencialmente de emancipação, esforço-me em traduzi-lo, enquanto prática política de leitura, a partir da noção de gênero, segundo teorias que diagnosticam e problematizam a condição do corpo da mulher como objeto de discursos e práticas de opressão. Para tanto, parto da hipótese de que a forma como o romance de Isabela foi escrito aproxima-o da noção de “escrita de si”. Dessa maneira, o romance se torna a expressão de um corpo falante, que se contrapõe à noção do sujeito Mulher.
EL EFECTO DE LA DIVERSIDAD DE SOCIOS DE RELACIONES INTERORGANIZACIONALES EN LA INNOVACIÓN DE PRODUCTOS
Authors: Montoro-Sánchez Ángeles , Garavito-Hernández Youseline , Romero-Martínez Ana M.
Published: August 2021

RESUMEN El objetivo de este estudio es analizar el impacto de la diversidad del tipo de socios en las relaciones interorganizacionales en la innovación de productos. La contrastación empírica con datos del Panel de Innovación Tecnológica de España muestra que la diversidad de tipos de socios en las relaciones interorganizacionales influye positivamente en la innovación de productos. En concreto, se pueden obtener mayores beneficios en la innovación de bienes cuando hay diversidad de relaciones entre socios comerciales (clientes y proveedores); y en la innovación de servicios con diversidad de relaciones entre socios no industriales (consultores, universidades y entidades de investigación). Finalmente, los resultados no permiten afirmar que demasiada diversidad produce rendimientos decrecientes en la innovación.

RESUMO O modelo Profluxo, elaborado no final dos anos de 1980 para resolver o problema da falta de informação nos recenseamentos escolares, visava aprimorar os modelos de análise de fluxo escolar com base na fonte de dados demográficas. Desde então a ferramenta foi aplicada em diversos trabalhos, especialmente aqueles interessados no diagnóstico e na correção do fluxo escolar. Este texto, orientado para profissionais com formação na área de ciências sociais e humanidades, traz um passo a passo didático da aplicação desse modelo.
Mathematical knowledge and overall practice in initial teacher education of early childhood teachers

Published: August 2021

ABSTRACT This paper presents an instrumental multiple-case study composed of two representative cases selected from a Mathematics Initial Teacher Education course. Data collected include concept maps, classroom observations, and interviews, which were analysed quantitatively and qualitatively. Differences in knowledge and practices were compared between pre-service early childhood teachers: one with greater content and pedagogical knowledge, and appropriate teaching practices; and another, with insufficient content and pedagogical knowledge, and repetitive mathematics activities. Findings from these two cases indicate a relationship among content, pedagogical knowledge, and good practice; and thus, support the existence of a dialogical and integrative relationship between knowledge and practice in teaching. Accordingly, the teacher practice dimension from the Mathematics Teaching Capability framework should play an important role in the initial teacher education of early childhood teachers.
