Published: June 2020

Abstract. The entrainment and suspension of sand and gravel are
important for the evolution of rivers, deltas, coastal areas, and submarine
fans. The prediction of a vertical profile of suspended sediment
concentration typically consists of assessing (1) the concentration near the
bed using an entrainment relation and (2) the upward vertical distribution of
sediment in the water column. Considerable uncertainty exists in regard to
both of these steps, especially the near-bed concentration. Most
entrainment relations have been tested against limited grain-size-specific
data, and no relations have been evaluated for gravel suspension, which can
be important in bedrock and mountain rivers. To address these issues, we
compiled a database with suspended sediment data from natural rivers and
flume experiments, taking advantage of the increasing availability of
high-resolution grain size measurements. We evaluated 12 dimensionless
parameters that may determine entrainment and suspension relations and
applied multivariate regression analysis. A best-fit two-parameter equation
(r2=0.79) shows that near-bed entrainment, evaluated at 10 % of
the flow depth, decreases with the ratio of settling velocity to
skin-friction shear velocity (wsi/u∗skin), as in
previous relations, and increases with Froude number (Fr), possibly due to its
role in determining bedload-layer concentrations. We used the Rouse equation
to predict concentration upward from the reference level and evaluated the
coefficient βi, which accounts for differences in the turbulent
diffusivity of sediment from the parabolic eddy viscosity model used in the
Rouse derivation. The best-fit relation for βi (r2=0.40) indicates greater relative sediment diffusivities for rivers with
greater flow resistance, possibly due to bedform-induced turbulence, and
larger wsi/u∗skin; the latter dependence is
nonlinear and therefore different from standard Rouse theory. In
addition, we used empirical relations for gravel saltation to show that our
relation for near-bed concentration also provides good predictions for
coarse-grained sediment. The new relations extend the calibrated parameter
space over a wider range in sediment sizes and flow conditions compared
to previous work and result in 95 % of concentration data throughout the
water column predicted within a factor of 9.
The Flexible Ocean and Climate Infrastructure version 1 (FOCI1): mean state and variability

Published: June 2020

Abstract. A new Earth system model, the Flexible Ocean and Climate Infrastructure (FOCI), is introduced.
A first version of FOCI consists of a global high-top atmosphere (European Centre Hamburg general circulation model; ECHAM6.3) and an ocean model (Nucleus for European Modelling of the Ocean v3.6; NEMO3.6) as well as sea-ice (Louvain-la-Neuve sea Ice Model version 2; LIM2) and land surface model components (Jena Scheme for Biosphere Atmosphere Coupling in Hamburg; JSBACH), which are coupled through the OASIS3-MCT software package.
FOCI includes a number of optional modules which can be activated depending on the scientific question of interest.
In the atmosphere, interactive stratospheric chemistry can be used (ECHAM6-HAMMOZ) to study, for example, the effects of the ozone hole on the climate system.
In the ocean, a biogeochemistry model (Model of Oceanic Pelagic Stoichiometry; MOPS) is available to study the global carbon cycle.
A unique feature of FOCI is the ability to explicitly resolve mesoscale ocean eddies in specific regions. This is realized in the ocean through nesting; first examples for the Agulhas Current and the Gulf Stream systems are described here.
FOCI therefore bridges the gap between coarse-resolution climate models and global high-resolution weather prediction and ocean-only models. It allows to study the evolution of the climate system on regional and seasonal to (multi)decadal scales. The development of FOCI resulted from a combination of the long-standing expertise in ocean and climate modeling in several research units and divisions at the Helmholtz Centre for Ocean Research Kiel (GEOMAR).
FOCI will thus be used to complement and interpret long-term observations in the Atlantic, enhance the process understanding of the role of mesoscale oceanic eddies for large-scale oceanic and atmospheric circulation patterns, study feedback mechanisms with stratospheric processes, estimate future ocean acidification, and improve the simulation of the Atlantic Meridional Overturning Circulation changes and their influence on climate, ocean chemistry and biology. In this paper, we present both the scientific vision for the development of FOCI as well as some technical details. This includes a first validation of the different model components using several configurations of FOCI. Results show that the model in its basic configuration runs stably under pre-industrial control as well as under historical forcing and produces a mean climate and variability which compares well with observations, reanalysis products and other climate models. The nested configurations reduce some long-standing biases in climate models and are an important step forward to include the atmospheric response in multidecadal eddy-rich configurations.
Dynamic parameters identification of a haptic interface for a helicopter flight simulator
Authors: Zhao Dingxuan , Zhang Jianyao , Carbone Giuseppe , Yang Haojie , Ni Tao , Yao Shuangji
Published: June 2020

Abstract. The haptic interface force feedback is one of the key
factors for a reliable flight simulation. This paper addresses the design
and control implementation of a simple joystick-like haptic interface to be
used for a helicopter flight simulator. The expression of the haptic
interface force is obtained by dynamic analysis of the haptic interface
operation. This paper proposes a new strategy aiming at avoiding the use of
an expansive and complex force/torque sensor. Accordingly, specific dynamic
model is implemented by including Stribeck friction to describe the friction
moment. Experimental data are processed as based on a genetic algorithm for
identifying the dynamic parameters in the Stribeck friction model. This
allows to obtain the friction moment parameters of the haptic interface, as
well as the torque distribution due to gravity and the rotational inertia
parameters of the haptic interface for the calculation of the haptic
interface force. Experimental tests are carried out and results are used to
validate the proposed dynamic model and dynamic parameter identification
method and demonstrate the effectiveness of the proposed force feedback
while using a cheap photoelectric sensor instead of an expansive
force/torque sensor.
Inter-and Intra-annual Surface Velocity Variations at the Southern Grounding Line of Amery Ice Shelf from 2014 to 2018
Authors: Chi Zhaohui , Klein Andrew G.
Published: June 2020

Abstract. The ice flow rate through the grounding line of the Amery Ice Shelf (AIS) is vital to understanding the mass discharge received from its three primary tributary glaciers. Previous studies have indicated a stable multiyear average surface velocity distribution in the convergence area of AIS. However, the surface velocity variations, especially short-term fluctuations, in the AIS have been relatively undocumented. This study investigated inter-annual and intra-annual surface velocity variations along the southern segment of AIS grounding line from 2014 to 2018. Using feature tracking to derive surface velocity for five consecutive austral summers and winters, it was found that AIS’s upstream end has experienced a steady ~ 5 % inter-annual increase in surface velocity. Surface velocity increases were observed in 2014/2015 (0.25 ± 0.02 m/d) and in 2017/2018 (0.21 ± 0.02 m/d) respectively. Surface velocities in winters were lower than the summers except for 2016, which had a 0.12 m/d surface velocity decrease from winter to summer. Although flowing slower than the other two glaciers, Fisher Glacier exhibited the highest inter-annual increase (8.56 ± 4.36 %) and the largest intra-annual variation (−5.41 ± 5.65 %) in surface velocity of the three studied glaciers. While the surface velocity observed in 2018 was generally close to the observed velocity in 1989, the magnitude of velocity variations observed during the 2014–2018 period is similar to the differences in velocities measured at the grounding line since 1989. This indicates continued relative stability in the surface velocities at the grounding line of these three tributary glaciers but also indicates that caution should be applied when interpreting long-term differences based on a limited number of measurements. This study demonstrated the capability of feature tracking to monitor the multidecadal changes of surface velocity.
Political Instability and Economic Growth in the State of Yemen Analysis Study
Authors: Alomaisi Najeeb
Published: June 2020

This paper explores the drivers of political instability and how political instability affects the economy in the context of Yemen. It is a low country income, although the critical location is at the southern end of the Arabian Peninsula with 200 islands. The country is rife with terrorists and lives under much socio-political strife. We implemented an empirical model to test the correlations and multiple regression between political instability and economic growth. The study found that there is a high negative correlation between volatility and economic growth with negative correlations value. Furthermore, we investigate the significance of the regression -enter method- stepwise method which show the existence of the impact of the political instability index conflict, and civil war in economic growth.
“The Master of Menace”: Pinter's Final Stand inSleuth
Authors: Jarrett James Alexander
Published: June 2020

Today, Harold Pinter is still one of the most studied, analyzed, and discussed playwrights of the twentieth and twenty-first centuries. And yet, while there is much excellent material available that addresses his enigmatic earlier dramas, and his middle period as an author of “political” plays, there is far less analysis of the work he produced in his later years. This article investigates his last screenplay, an adaptation of a 1970s British psychological thriller. This article demonstrates how Sleuth is a projection, and a violent expression, of Tindle's and Wyke's patriarchal urges to establish and maintain social, sexual, and masculine power over “Maggie,” and one another. The article explores and explicates how, through the application of a variety of complex verbal and nonverbal stratagems, the men seek to maintain and strengthen their psychological advantage. The work also addresses a range of other issues including epistemology, performance, and identity. It is important to note that the subject of this article is the text of Pinter's film script and the film itself.
Promethean Commerce and Ayn's Alloy
Authors: Donway Roger
Published: June 2020

Sixteen essays on Ayn Rand's contribution to economic and business thought question, explore, and extend what makes her writings such a prominent inspiration to businessmen and free-market economists. Most of the contributors agree it is principally her use of a Romanticist literary style, which restored the nineteenth century's idealization of inventors, engineers, and entrepreneurs. Some also believe that she brought philosophic depth to the analysis of business by adding wealth creation to the traditional Aristotelian morality of self-realization. A few credit her invocation of a nonexploitative egoism to oust the image of businessmen as servants of shareholders and customers.

Authors: Radovic Aleksandar , Cerovic Radosav , Milatovic Dragan , Nikolic Dragan
Published: June 2020

Aim of study: To determine the self-compatibility level of eight quince cultivars.Area of study: The region of Belgrade (Central Serbia).Material and methods: Pollen tube growth in vivo and fruit set in two pollination variants (self- and open-pollination) were studied in eight quince cultivars. The quantitative parameters of pollen tube growth (average number of pollen tubes in the upper and middle third of the style, base of the style and in the ovary; the dynamics of pollen tube growth through these parts of the pistil) was determined using the fluorescence microscopy.Main results: The parameters of pollen tube growth and fruit set were primarily dependent on the genotype and variants of pollination. All studied parameters were significantly higher in the open-pollination variant compared with the self-pollination in all cultivars. In the self-pollination variant, ʻLeskovackaʼ and ʻVranjskaʼ had the highest number of pollen tubes that penetrated the ovary (2.10 and 0.54 in average, respectively), as well as the largest percentage of pistils with the penetration of pollen tubes in the nucellus of ovules six days after pollination (40.09% and 14.74%). Also, they had the highest percentage of initial fruit set (17.01% and 28.52%) and final fruit set (9.32% and 9.86%). Based on this, ʻLeskovackaʼ and ʻVranjskaʼ can be classified as self-compatible cultivars, while the others are self-incompatible.Research highlights: The majority of quince cultivars were self-incompatible. When establishing new orchards with these cultivars, care should be taken about the choice of pollenisers in order to achieve high yields.

Background: Brucellosis is a bacterial zoonotic disease of public health and economic importance. A cross-sectional study was conducted in Mbeya region between November 2015 and January 2016 to investigate the seroprevalence of human brucellosis and identify associated risk factors among individuals in risky occupations. Methods: A total of 425 humans from six occupational categories were serially tested for Brucella antibodies using the Rose Bengal Plate Test (RBPT) and competitive Enzyme Linked Immunosorbent Assay (c-ELISA), for screening and confirmation, respectively. A questionnaire survey was also administered to participants to collect epidemiological data. Results: The overall seroprevalence among the occupationally exposed individuals was 1.41% (95% CI: 00.64-3.12). Seroprevalence was higher among butcher men 5.6% (95% CI: 1.68-5.26), herds men 1.35% (95% CI: 0.18-9.02); and abattoir workers 1.1% (95% CI: 0.26-4.22) although there was no statistical significance. (P value = .18). Seroprevalence was also higher among men (1.8%) compared to females (0%) (P value = .19). and also, among those aged < 11 years (2.5%). Individuals who consumed raw milk had a higher seroprevalence (1.56%) compared to those who drunk boiled milk while seropositivity was 0.88% among those who assisted animals during parturition (P value = .49). Butcher men were at higher risk of exposure compared to other occupational categories. Our findings show the presence of brucellosis in occupationally exposed individuals in Mbeya region.Conclusion: There is need to sensitize the concerned professions in order to reduce the risk of acquiring Brucella infections from animals and animal products This also calls for public health awareness about the disease, and implementation of measures to prevent further spread of brucellosis within and outside the study area.

All citizens investigate crimes

Citizens investigating crimes themselves is a growing trend, because of democratization of information (e.g. social media), tools (e.g. apps) and knowledge (e.g. explanimations on YouTube). More and more citizens do their own research as modern Sherlocks. The police has to handle these trends in line with participant wishes and the law, but does not yet have concrete tools to do so. This article explores how the police participate in contemporary citizen criminal investigations, including the difficulties and benefits experienced. The obtained insights of the presented research serve as guidance, which can help police officers understand how to participate with citizens who have started, or want to start, a criminal investigation. The presented model explains how police can use it to better guide and stimulate, but also stop or protect citizens in their investigative activities. An app with professional guidance was piloted in four police units to participate with citizens that do their own research and learn from expectations and experiences. Citizens need guidance, but more importantly expect a certain degree of reciprocity in collaborating with police in criminal investigations.

Integrating spatial data from different sources results in visualization, which is the last step in the process of digital basic topographic map creation. Digital elevation model and visualization will used for geomorphological mapping, geospatial database, urban planning and etc. Large scale topographic mapping in the world countries is really a prominent challenge in geospatial industries today. The purpose of this work is to integrate laser scanner data with the ones generated by aerial photogrammetry from UAV, to produce detailed maps that can used by geodetic engineers to optimize their analysis. In addition, terrestrial - based LiDAR scans and UAV photogrammetric data were collected in Sharga hill in the north zone of Mongolia. In this paper, different measurement technology and processing software systems combined for topographic mapping in the data processing scheme. UTM (Universal Transverse Mercator) projected coordinate system calculated in WGS84 reference ellipsoid. Feature compilation involving terrestrial laser scanner data and UAV data will integrated to offer Digital Elevation Models (DEM) as the main interest of the topographic mapping activity. Used UAV generate high-resolution orthomosaics and detailed 3D models of areas where no data, are available. That result issued to create topographic maps with a scale of 1:1000 of geodetic measurements. Preliminary results indicate that discontinuity data collection from UAV closely matches the data collected using laser scanner.
Educação infantil dialógica e não-violenta
Authors: Gaidargi Alessandra Maria Martins
Published: June 2020

Na educação infantil muitas violências silenciosas podem ser cometidas contra a criança, e é necessária a revisão de práticas, por vezes vistas como habituais no ambiente escolar, a fim de quebrar este ciclo de violências verbais e psicológicas às quais alunos deste nível de ensino são por vezes submetidos. A utilização da comunicação não-violenta nas escolas de educação infantil é uma forma de trabalhar os processos educativos de forma gentil, envolvendo uma nova linguagem e atitudes voltadas ao respeito mútuo. O desenvolvimento respeitoso da personalidade infantil tem, por consequência, a melhoria de sua relação com a comunidade escolar e com a educação por toda a vida. A proposta desta mudança de paradigma para a educação atual, apresentando um caminho para a diminuição efetiva da violência escolar sem medidas punitivas e por meio de diálogo, representa um novo olhar sobre a criança e a escola.

Published: June 2020

Partimos do princípio que Educação Sexual é um dos mais polêmicos assuntos, tendo em vista os diversos olhares, percepções e concepções existentes, recheados de diferentes valores presentes na sociedade. Dentre os estudiosos que se aventuram em investir na compreensão da sexualidade estão alguns profissionais da saúde e da educação, para quem direcionamos este artigo, que tem como objetivo refletir sobre os conceitos de Educação, Educador e Educação Sexual, levando o leitor a ponderar suas convicções sobre o papel de educador e refletir sobre a necessidade da ampliação desta temática para áreas de atuação além da Educação e Saúde. Trabalhar com Educação Sexual é uma possibilidade que vai além do ambiente escolar e médico, principalmente no momento atual em que as relações sociais se expandem em diferentes espaços e áreas profissionais começam a surgir para dar conta da demanda de questões ligadas à sexualidade. As reflexões aqui descritas, são decorrentes de leituras bibliográficas, que levam à conclusão que, mesmo diante de inúmeros desafios da Educação Sexual, todo cidadão pode ser educador em sexualidade, desde que exista nele o interesse pelos estudos e pesquisas para aprofundamento sobre a temática, encarando-a como formativa e de cunho científico.
Representações sociais da ressocialização através da Educação: a prisão pode constituir-se em espaço educativo?
Authors: Oliveira Eloiza Da Silva Gomes de , Melo Ronaldo Silva
Published: June 2020

Este artigo deriva de pesquisa realizada com 80 sujeitos, em dois presídios masculinos do Rio de Janeiro, com o objetivo de identificar representações sociais da ressocialização por meio da educação. Apresentamos aspectos relacionados à percepção da escola e a uma representação social que emergiu na análise dos dados coletados: a de “enquadramento”, uma série de atitudes e pensamentos que permitem a sobrevivência no interior do presídio. Concluímos afirmando três necessidades imperativas: a construção de uma concepção de educação prisional não como benesse, mas como direito cidadão; o investimento material e humano nos espaços educativos situados em ambiente prisional; e a existência de uma verdadeira escola de ressocialização. Esta escola não pode ser representada como derivada do “enquadramento” dos presidiários, mas atuar para o mundo externo e promover a constituição de redes de apoio no contexto “extra muros”, contemplando também as famílias dos presidiários.

Este artigo tem como objetivo situar o papel do professor de matemática como agente sociocultural e político promotor da inclusão de alunos imigrantes na atividade matemática, bem como no espaço escolar. Nesse sentido, buscamos responder: qual o papel do professor de matemática frente ao fenômeno das migrações? Reconhecendo, fundamentalmente, o professor de matemática como agente sociocultural e político que promove a inclusão de alunos imigrantes. Como embasamento teórico, abordamos as perspectivas de Educar em Direitos Humanos de Candau et al. (2013) e da Educação Matemática Inclusiva de Vieira e Moreira (2018) e para compreendermos os conceitos lugar e território recorremos à geógrafa Doreen Massey (2000; 2008; 2017) e a Haesbaert (1997; 2014). Por fim, concluímos que a postura do professor frente a todas as formas de discriminação e preconceito faz uma profunda diferença no cotidiano dos estudantes. E que a materialização do conhecimento matemático, nesse contexto, tem como possibilidade a resolução de problemas e a investigação matemática que incorporem conteúdos de cunho político e social.

Labor Issues in Sociological Research into the Social Aspects of Industrialization: The Circle of Kazimierz Dobrowolski
Authors: Górski Piotr
Published: June 2020

The objective of this article is to present one of the lineages of human resource management in Poland—industrial sociology. It was within the framework of this subdiscipline that research devoted to the social aspects of industrialization was carried out in the nineteen–sixties and seventies. Studies conducted within the circle of the Cracovian sociologist, Kazimierz Dobrowolski, looked at the industrial centers of Lesser Poland. The primary research question involves the process of the shaping of industrial company personnel in connection with the migration of rural population to industrial centers. The research demonstrated the social and cultural conditions behind this process, not only the impact of the culture of rural communities on shaping work culture in companies, but also the influence of industrial work experience on the life and cultural aspirations of rural communities.

Authors: Peplińska Aleksandra , Kawalec Katarzyna , Godlewska-Werner Dorota , Połomski Piotr
Published: June 2020

The aim of the presented study was to verify the relationship between the level of work engagement and organizational commitment and work satisfaction experienced by employees, taking into account intermediary variables—i.e. the climate at the organization and the phenomenon of silence in the organization. The survey involved a total of 131 employees of the National Revenue Administration, including 35 males and 96 females. Five methods were used to verify the questions and research hypotheses: Allen and Meyer’s Organizational Commitment Scale, the AVEM questionnaire, Paluchowski’s Organizational Climate Questionnaire, the four forms of the Organizational Silence Scale, and the Job Descriptive Index (JDI). The results of the research show that there is a significant relationship between work engagement and organizational commitment and work satisfaction.
Manipulating Complex Robot Behavior for Autonomous and Continuous Operations
Authors: Liu Chengliang , Gong Liang , Zhang Wei
Published: June 2020

Service robot control faces challenges of dynamic environment and complex behavior, which mainly include eye-hand coordination and continuous operations. However, current programming scheme lacks the ability of managing such tasks. In this chapter, we propose a methodology of software development paradigm for the continuous operation of the dual-arm picking robot. First, a dual-arm robot is built for picking with the purpose of selectively harvesting in plant factory. Second, a hierarchical control software is framed by means of “Sense Plan Act” (SPA) paradigm. Third, based on the previous design, programming concept, and the ROS system, the sub-node programming of visual module, motion module, eye-hand coordination module, and task planning module are implemented with a state machine-based architecture. The experimental results show that if total number of targets within the visual field is not more than three, the average picking time is less than 35 s. The fluency of concurrent task management shows the feasibility of manipulating complex robot behavior for autonomous and continuous operations with the finite state machine model and task level architecture.
Plum Breeding
Authors: Butac Madalina
Published: June 2020

Worldwide, plum is one of the main species, occupying an area of about 2,600,000 ha and ensuring production about 11,700,000 tons. Even though there are over 6000 plum cultivars belonging to 19–40 species, there is still the need to create new cultivars due to the demands of growers and consumers. In addition, the large plum-growing countries (Romania, Serbia, Germany, Bulgaria, etc.) have decreased production due to plum pox virus (PPV) attack. Therefore, these countries developed breeding programs with the following objectives: resistance/tolerance to PPV, productivity, fruit quality, late blooming, self-fertility, different ripening times, short growing period, spur fructification, etc. Using different breeding methods (controlled hybridization, open pollination, selection in wild population on Prunus sp., and mutagenesis), in the last years, over 450 plum cultivars were released, from which 70% represent European cultivars and 30% Japanese cultivars.

Authors: A. Alexeyeva Lyudmila , K. Zakiryanova Gulmira
Published: June 2020

The method of boundary integral equations is developed for solving the nonstationary boundary value problems (BVP) for strictly hyperbolic systems of second-order equations, which are characteristic for description of anisotropic media dynamics. The generalized functions method is used for the construction of their solutions in spaces of generalized vector functions of different dimensions. The Green tensors of these systems and new fundamental tensors, based on it, are obtained to construct the dynamic analogues of Gauss, Kirchhoff, and Green formulas. The generalized solution of BVP has been constructed, including shock waves. Using the properties of integrals kernels, the singular boundary integral equations are constructed which resolve BVP. The uniqueness of BVP solution has been proved.
Beyond the Quality of Life in Bowel Dysfunction after Spinal Cord Injury: Approaches to the Consequences in Motility, Immune System, and Microbiome
Authors: de la Cruz-Castillo Estefanía , García-Vences Elisa
Published: June 2020

Spinal cord injury (SCI) is a harmful event that involves several repercussions on sensory and motor function that affects the quality of life (QoL) of patients. After SCI, many damage mechanisms are activated that impact on both autonomous extrinsic and intrinsic innervation toward the gut, and these changes modify the gut motility causing bowel dysfunction (BD), an entity that affects 40% of patients with SCI, being the second comorbidity after loss of mobility with no recognized cure. The severity of complications is ruled by the level and severity of injury, having a worse prognosis with an injury that is the most proximal to the brain. In the last 5 years, some experiments have tried to elucidate the consequences of dysbiosis in the gut and aggregated proinflammatory processes. The goal of this chapter is to establish the importance of bacterial composition and immune system repercussions in bowel dysfunction after SCI and how could it give rise to new therapies.
Truth in Education and Science
Authors: Sørensen Asger ,   Philosophy Documentation Center
Published: June 2020

The growing number of universities today makes it relevant to consider again the idea of the university. Consulting the classics of the discussion, I argue that we must retain the idealist notions of knowledge, science and truth professed by Newman in his argument for liberal education, although he neglects the possible corruption of the university faculty. The problem of corruption is recognized by Jaspers, criticizing all idealist notions and leaving science and scholarship to rely only on existential commitment. The problem for both classics, however, is that they conceive of academic freedom in an all-too individualist way. Instead, I argue that the idea of the academic republic should be taken seriously, i.e., that a contemporary idea of the university must include suggestions for university government comprising institutional checks and balances. Only such a constitutional notion of academic freedom may counter neo-liberal reification of higher education, science, and scholarship.
O brinquedo e o brincar: apontamentos vigotskianos
Authors: Dametto Jarbas , Bragagnolo Adriana
Published: June 2020

Este artigo busca explorar as concepções acerca do brinquedo e do ato de brincar presentes na obra de Vigotski, salientando o papel desta experiência no curso normal do desenvolvimento infantil. Para tal, discorre-se sobre alguns posicionamentos sobre o tema considerados equivocados pelo autor, mapeando os motivos de suas contestações, bem como se busca evidenciar a própria concepção vigotskiana do brincar, e suas implicações práticas no desenvolvimento psíquico. Por fim, comenta-se o paralelo, indicado pelo autor, entre o brincar, a criação e a linguagem infantil, enquanto experiências significativas no processo de internalização das funções mentais superiores, bem como as potencialidades do manejo pedagógico da atividade lúdica.Palavras-chave: Brinquedos. Crianças - Desenvolvimento. Vigotsky, L. S. (Lev Semenovich), 1896-1934.

“But how could anyone rationalize policies that discriminate?: Understanding Canada’s Failure to Implement Jordan’s Principle
Authors: King Jennifer
Published: June 2020

This article seeks to understand Canada’s failure to implement Jordan’s Principle, a child-first policy ensuring First Nations have access to the same level and quality of services available to other children. Policy-making in Canada rests firmly within a neoliberal political framework that extends market-based thinking to all aspects of social life. Neoliberal thought interlocks with stories of Other to inform notions of deservingness as well as one’s potential as a valuable citizen with something to contribute. Social policy decisions, including the decision to implement a particular policy or not, offer a means through which to disseminate neoliberal values and norms. As self-determining peoples with distinct rights, lands, and governance structures, First Nations transgress the image of the “good” neoliberal citizen in a variety of ways. Neoliberalism holds that punitive measures are sometimes needed to encourage citizens to adopt particular norms, and this allows policy makers to rationalize and justify policies that discriminate against First Nations children. Stereotypes about Indigenous peoples are also used to manipulate public sentiment in favour of government policy. Canada’s failure to implement Jordan’s Principle can be understood as part of a broader strategy to encourage First Nations to rescind their distinct rights and assimilate as good neoliberal citizens.
Early Learning for Aboriginal Children: Past, Present and Future and an Exploration of the Aboriginal Head Start Urban and Northern Communities Program in Ontario
Authors: Mashford-Pringle Angela
Published: June 2020

This article provides some key findings from a case study of the Aboriginal Head Start Urban and Northern Communities (AHSUNC) Program in Ontario. Some of the key findings were improved self-reported health status, commitment to cultural and linguistic revitalization, reduced tobacco use, improved knowledge of healthy living practices among Aboriginal children and their families. The number of off-reserve Aboriginal children that can experience AHSUNC is limited by funding and availability of space and human resources. The participants in this study have shown improved knowledge, interaction with their children, and increased understanding of their biculturedness within Ontario. Therefore it is important to increase this funding and continue to conduct research with AHSUNC projects across Ontario to document and highlight their successes as a model for other provinces/territories and early childhood programs.
Wanted: Moral Courage in Canadian Child Welfare
Authors: Blackstock Cindy
Published: June 2020

Child welfare stifles change and innovation in a system that desperately needs it by promoting conformity and awarding subordination to bad ideas (Blackstock, 2009). If neglect means not doing the right thing for children even when you know better and can do better, and have the resources to do it, then too often child protection neglects First Nations children and their families. This essay explores whether emancipating moral courage in child protection is the key to ensuring good research translates into real benefits for First Nations families. This paper begins with a description of moral courage in child protection across the decades before drawing on my own experiences with moral courage in the child welfare field. It concludes with stories of how moral cowardice diminishes children and how moral courage uplifts them. Implications for research, policy and practice are discussed.
Using a Western-Based Survey to Assess Cultural Perspectives of Dene Mothers in Northern Manitoba
Authors: Jonk Luella Bernacki
Published: June 2020

With increasing numbers of immigrants entering Canada over the past several decades, educators have become more sensitive to the various genres of communication competence and discourse patterns within a given culture. This is especially true for the Aboriginal students struggling to acclimate into Western curricula. The purpose of this study was to explore Aboriginal mothers’ perspectives on language acquisition for their children. Thirty Dene speaking mothers from a northern first nation community were administered a survey in a face to face format. The survey was replicated in part from previous studies on language acquisition of cultural groups in Canada. This paper will describe the challenges in trying to adapt such a survey, including issues of administration, translation, and survey validity and reliability. Challenges in adhering to Western research standards while displaying cultural sensitivity to its participants by way of acknowledging the community’s indigenous knowledge and English as an alternative language (EAL) issues are discussed.
