“Let’s Just Spend a Ton of Time Together Building This Thing That’s so Important:” Children’s Theory Development in American Jewish Early Childhood Classrooms

ABSTRACT The concept of children’s theories is central to the approach of the municipal infant-toddler centers and preschools of Reggio Emilia, Italy. The author investigates children’s theories about Judaism. Methods include semi-structured interviews and pedagogical documentation from American Jewish early childhood centers. Analysis involves open coding toward the development of a grounded theory positing that (1) children hold theories that impact the Jewish education they experience and (2) when the Jewish learning experience aligns with these inherent theories, children develop a new mental model, that they can make their mark on Judaism.

The influence of organisational learning ambidexterity on process innovation performance: the role of KM capability

ABSTRACT This study examined the relationship between organisational learning ambidexterity and process innovation in micro and small sized companies and the moderating role of Knowledge Management capability. Exploratory and exploitative learning were conceptualised as multi-dimensional constructs occurring at team and organisational level and as inter-organisational and intra-organisational processes. Regarding the organisational learning ambidexterity, the combined approach was used, which assumes that exploratory and exploitative learning are mutually supportive. Knowledge Management capability was based on three knowledge processes: knowledge acquisition, sharing, and application. Due to the relative lack of validated understanding of the organisational learning ambidexterity effects on process innovation, it contributes to the development of theory explaining this interaction and its effects. The results provide additional insights whether exploitative and exploratory learning are complementary. Finally, Knowledge Management capability plays an important role in the relationship between organisational learning ambidexterity and process innovation.

Взаимосвязь билингвального языкового опыта и исполнительных функций: современное состояние исследований

<p style="text-align: justify;">Bilingualism has been claimed to enhance executive functions, as evidenced by studies comparing bilinguals and monolinguals across various executive function tasks. Despite this assertion, recent systematic reviews and meta-analyses reveal contradictory findings, challenging the existence of the “bilingual advantage” phenomenon. The variability in results is attributed not to the data obtained but rather to the diverse methodological paradigms utilized across studies. This article analyzes the operationalization of bilingualism and executive functions in contemporary research alongside a critical examination of the theoretical underpinnings linking bilingualism and executive functions. The paper concludes by outlining avenues for future research, emphasizing the necessity for researchers to account for individual bilingualism-related factors and specifics of the executive function tasks. Furthermore, it advocates for the development of new falsifiable theories that suggest testable hypotheses, thus advancing the field's understanding of bilinguals’ executive functioning.</p>

The need for proactive environmental planning in local government: Examining challenges and pathways forward in Indiana

ABSTRACT Many factors, including regulations, community values, and economic and environmental considerations, influence environmental planning decisions. Across the nation, local elected and appointed boards and commissions are responsible for planning and land use regulations. However, few studies have focused on environmental planning through comprehensive and parks and recreation plans. Using Indiana communities as a case study, this research highlights the theory and practice of environmental planning and community development, emphasizing the importance of collaboration and the presence of social capital. Statewide focus groups found that communities integrate varying environmental planning processes into comprehensive and parks and recreation plans. As a result, these plans represent underutilized potential to guide conservation and collaboration. Integrating environmental planning into local government activities is limited by time, political will, and community awareness. As such, communities need continued support and resources to build social capital that leads to engaging with the public, decision-makers, and collaborators in meaningful ways to foster effective environmental planning.

Cameroon and its 21st Century Challenges towards Achieving Sustainable Development: Appraisals and Proposals

Purpose: This study presents an appraisal of some of the dynamics which Cameroon continues to face in the 21st Century in its quest to achieve sustainable. Using various indicia, the study identifies and proffers explanation why the country continues to face surmountable challenges in its pursuit towards achieving sustainable development. To attain this objective, a broad review of published literature was employed using various journal articles, textbooks, internet sources, etc. Methodology: The study adopts a qualitative research methodology in the interpretation of data. These data are both primary and secondary derived from laws, text books, journal articles, reports, working papers and other internet sources. This study adopts an analytical approach in the interpretation of the available data. Findings: The study observes that irrespective of existence of deterrent penal laws, policy formulations from international organization and support from foreign donor institutions, the country is not yet on the path towards sustainably sound environmental practices. Cameroon is engulf in a number of challenges both internal and external, which has accounted for continuous impoverishment of its population, social progress and economic advancement of the country generally. The Study employs the post-colonial and dependency theories of development to justify some of the key findings. The internal challenges revealed in the study ranges from the continuous prevalence of poverty and hunger, corruption and misappropriation, lack of judicial independence, the prevalence of conflicts, environmental degradation and poor enforcement measures. Similarly, this study also found the underlying external challenges to include the Structural Adjustment Programmes, the influence of Foreign Financial Institutions, and neo-colonialism. Unique Contribution to Theory, Practice and Policy: This study therefore concludes that strengthening enforcement measures, effective implementation of poverty alleviation policies, fight against corruption and misappropriation, and citizen participation can positive contribute to sustainable development in the Cameroon.

On the Continuity Equation in Space–Time Algebra: Multivector Waves, Energy–Momentum Vectors, Diffusion, and a Derivation of Maxwell Equations

Historically and to date, the continuity equation (C.E.) has served as a consistency criterion for the development of physical theories. In this paper, we study the C.E. employing the mathematical framework of space–time algebra (STA), showing how common equations in mathematical physics can be identified and derived from the C.E.’s structure. We show that, in STA, the nabla equation given by the geometric product between the vector derivative operator and a generalized multivector can be identified as a system of scalar and vectorial C.E.—and, thus, another form of the C.E. itself. Associated with this continuity system, decoupling conditions are determined, and a system of wave equations and the generalized analogous quantities to the energy–momentum vectors and the Lorentz force density (and their corresponding C.E.) are constructed. From the symmetry transformations that make the C.E. system’s structure invariant, a system with the structure of Maxwell’s field equations is derived. This indicates that a Maxwellian system can be derived not only from the nabla equation and the generalized continuity system as special cases, but also from the symmetries of the C.E. structure. Upon reduction to well-known simpler quantities, the results found are consistent with the usual STA treatment of electrodynamics and hydrodynamics. The diffusion equation is explored from the continuity system, where it is found that, for decoupled systems with constant or explicitly dependent diffusion coefficients, the absence of external vector sources implies a loss in the diffusion equation structure, transforming it into Helmholtz-like and wave equations.

Characteristics of concurrent flame spread over convex charring materials

In real forest fire scenarios, there are a large number of convex and concave terrains at the junction of flat land and slopes. In this paper, a typical charring material, kraft paper, is selected as the experimental sample, and the variation law of key characteristic parameters of flame spread over convex solid surface are investigated. The experimental results show that all the flame spread processes have obvious deceleration behaviors, and the influence mechanism of flame tangent angle on the flame spread deceleration of convex surfaces is revealed. The characteristic length of the pyrolysis zone shows a tendency of increasing and then decreasing with time. The variation curves of radiant heat flux present two peaks. Combining with the characteristic length, the reason for the occurrence of two peaks is explained. The exponential relationship between the instantaneous mass loss rate and the characteristic length of the pyrolysis zone is obtained. Based on the range of power exponents, the heat transfer controlling mechanism in the pyrolysis zone is classified into three categories for all the working conditions. Moreover, a piecewise power-law relationship between the dimensionless maximum flame height and the dimensionless heat release rate is established. The results of this study will fill the research gap of flame spread of solid materials with curved surfaces, and will be of great academic value for the improvement and development of theories on building and forest fire safety.

Friendship Network and School Socialization Correlates of Adolescent Ethnic-Racial Identity Development.

Ethnic-racial identity (ERI) development is consequential for youth adjustment and includes exploration, resolution, and affect about the meaning of one's ethnic-racial group membership. Little is known about how identity-relevant experiences, such as ethnic-racial socialization and discrimination in peer relationships and school contexts, catalyze adolescent ERI development. The present study examines how identity-relevant experiences in friend and school contexts (i.e., proportion of same-ethnoracial friends, cultural socialization among friends, friends' ERI dimensions, friends' experiences of ethnoracial discrimination, and school promotion of cultural competence and critical consciousness) are associated with ERI development. A multivariate path model with a sample from four southwestern U.S. schools (N = 717; 50.5% girls; Mage = 13.76; 32% Latinx, 31.5% Multiethnic, 25.7% White, 11% other) was used to test these associations. Findings showed that friend and school predictors of ERI did not differ between early and middle adolescents, but significant differences and similarities emerged in some of these associations between ethnoracially minoritized and White youth. Specifically, friend cultural socialization was positively associated with ERI exploration for ethnoracially minoritized youth only, whereas school critical consciousness socialization was positively linked with ERI exploration only for White youth. Friend cultural socialization and friend network's levels of ERI resolution were positively associated with ERI resolution across both ethnoracial groups. These friend and school socialization associations were documented above and beyond significant contributions of personal ethnoracial discrimination to ERI exploration and negative affect for both ethnoracially minoritized and White youth. These findings expand our understanding of how friend and school socialization mechanisms are associated with adolescent ERI development, which is vital to advancing developmental theory and fostering developmental competences for youth to navigate their multicultural yet socially stratified and inequitable world.

Towards a Biologically Coherent Account of the Brain and How It Develops

Different conceptualizations of brain function have different implications for understanding the relation of neuroscience to the study of human development. In one view, the brain is an isolated computational device that passively processes stimuli delivered from an external world and then mediates a response. An alternative view, which is more consistent with the evolutionary history of brains, moves away from simple causal linkages between stimulus and response and instead emphasizes the inherent, ongoing activity of the individual. Here the individual is not directly instructed by information from its environment but instead shapes its own sensory inputs through its goal-directed activity. Related conceptual confusions around instructions and information can be found in accounts of brain development that either fall back on a genetic blueprint or that elevate the role of extrinsic experience. A more coherent approach brings together aspects of developmental and evolutionary biology while drawing on developmental systems theory and particular themes in embodied cognitive science. Such an approach spans qualitatively different frames of explanation across a range of spatiotemporal scales, necessitating a reconsideration of disciplinary boundaries. Fully engaging in this effort can yield a more integrative science of brain, mind, and behavior and an enriched understanding of human development.

Lev Gutman – A Pioneer in Theoretical Mesoscale Meteorology

Abstract On March 5, 2023, Professor Lev Gutman would have been 100 years old. This article describes Professor Gutman’s legacy in the field of dynamic mesoscale meteorology and numerical weather prediction. Gutman developed his career as a mathematician and meteorologist in the Soviet Union, where he built a school of specialists in mesoscale meteorology during the 1950s through the 1970s. He primarily worked on analytical methods to solve complex nonlinear problems, such as the structure of sea breezes, mountain-valley circulations, and thermal convection over heated terrain. Gutman pioneered the development of theories of cumulus clouds, tornados, and other atmospheric phenomena. In the 1960s, he carried out numerous research investigations on these topics with his doctoral students and collaborators at High-Altitude Geophysical Institute in Nalchik in the northern Caucasus and later at the Siberian scientific center near Novosibirsk. Gutman compiled the results from these studies into a monograph titled “Introduction to the Nonlinear Theory of Mesoscale Meteorological Processes”, which was published in Russian in 1969, and later translated into English, Chinese, and Japanese. This monograph became a major textbook for specialists in mesoscale meteorology, remaining relevant to this day. After Prof. Gutman immigrated to Israel in 1978, his collaborations expanded to include Israeli and western scientists from Europe and the United States. Gutman did not receive the recognition he deserved due to the political realities of the time. His book and his seminal analytical solutions should still be useful for early career scientists in mesoscale meteorology and atmospheric dynamics.

The impact of the digital technological revolution on the development of crisis management theory

Purpose: is to identify the main directions of changing the theory of crisis management of companies under the influence of digitalization based on the analysis of technological transformations in the economy and institutional prerequisites.Methods: to achieve the purpose of the study, methods of logical, institutional and statistical analysis of economic phenomena and financial and economic data of industrial and digital companies, economic comparative studies using the provisions of various theories are used. The theoretical basis of the research is the synthesis of the theory of technological revolutions by Perez C., the new institutional economic theory, the concept of scientific research programs by Lakatos I.Results: the formulated hypotheses of the study on the need to change the «protective shell» of the theory of crisis management under the influence of factors of the digital transformation of the institutional economy are proved. The changes are associated with the formation of new subjects – digital companies, the transformation of the nature of crises and anti-crisis tools in the context of the digital revolution. The institutional nature of business crises in the context of technological revolutions has been established, due to the discrepancy between the speed of development of the economic institutions and technologies.Conclusions and Relevance: the digital revolution is having a significant impact on business. Its adaptation to digital technological conditions requires the development of the new and improvement of existing institutions. These changes challenge the theory of management, which must adapt its basis to the new technological needs of the business. Сrisis management plays an important role in this: the rapid development of digital technologies is accompanied by the crisis factors, the nature of most of which is institutional in nature. However, to date, despite the obvious need, the directions of transformation of the theory of crisis management have not been determined at the scientific and theoretical level. According to the results of the study, the key artifacts of the digital economy have been identified that determine the directions of transformation of the theory of crisis management by transforming its «protective shell». The institutional nature of the prerequisites for such a transformation is proved. The results of the study determine the future directions of the development of the theory of crisis management.

Characterizing the dispersion behavior of poly-atomic magnetic metamaterials

The propagation of magnetoinductive (MI) waves across magnetic metamaterials known as magnetoinductive waveguides (MIWs) has been an area of interest for many applications due to the flexible design and low-loss performance in challenging radio-frequency (RF) environments. Thus far, the dispersion behavior of MIWs has been limited to mono- and diatomic geometries. In this work, we present a recursive method to generate the dispersion equation for a general poly-atomic MIW. This recursive method greatly simplifies the ability to create closed-form dispersion equations for unique poly-atomic MIW geometries versus the previous method. To demonstrate, four MIW geometries that have been selected for their unique symmetries are analyzed using the recursive method. Using applicable simplifications brought on by the geometric symmetries, a closed-form dispersion equation is reported for each case. The equations are then validated numerically and show excellent agreement in all four cases. This work simultaneously aids in the further development of MIW theory and offers new avenues for MIW design in the presented dispersion equations.

“I need more help, but everyone expects me to know it”: perceived mentoring needs of contemporary second-year early career teachers

ABSTRACT While there has been theoretical and empirical address of the changing characteristics of teachers as they progress through the early years of their professional careers, much less research has considered how this influences the changing ways in which early career teachers (ECTs) may prefer to experience mentoring during this time. Most ECT mentoring research and in-school mentoring programmes focus on teachers in their first year of the profession, or ECTs in very broad terms. Consequently, the specific mentoring needs and preferred approaches of second-year teachers, in particular, remain unclear. In this paper, we report on data collected via researcher field notes, an online survey, and professional learning activities with 15 mentors and ECTs in their second year of teaching in Queensland, Australia. Using a combination of descriptive statistics and directed qualitative content analysis, findings indicated that second-year teachers identify as having specific mentoring needs that they perceive require a unique combination of directive and co-exploratory mentoring approaches. Critically drawing on theories of teacher development, these findings have implications for schools and systems both in Australia and internationally in the development of policies and programmes for mentoring beyond the first year of teaching.

Review on 3D electromagnetic modeling and inversion for Mineral Exploration

Many mineral deposits demonstrate low-resistivity characteristics. This property makes the electromagnetic (EM) method a very useful tool for mineral exploration. In the past decades, the application of EM exploration technologies has been reviewed in many case studies. However, most reviews focused on EM exploration methods, the development of equipment, or their applications. The three-dimensional (3D) forward modeling and inversions are high-accuracy EM interpretation techniques that have made great progress in recent years in mineral explorations. In this paper, we make a review on the development of EM technology for mineral exploration with focus on 3D EM forward modeling, inversion technology, and its applications. We will first briefly introduce the EM methods for mineral explorations from the methodology. After that, we will give a comprehensive review of 3D EM forward modeling, inversions, and data interpretations, with special attention paid to the development of EM theory and applications in mineral explorations. We hope this review can promote the application of 3D EM numerical simulation and inversion in mineral explorations.

Philosophical Analysis of Sustainable Development Goals

Purpose: The general objective of the study was to examine philosophical analysis of Sustainable Development Goals. Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library. Findings: The findings reveal that there exists a contextual and methodological gap relating to philosophical analysis of Sustainable Development Goals. Preliminary empirical review revealed the crucial interplay of ethical, epistemological, and metaphysical considerations in achieving global sustainability. It highlighted the SDGs' foundation on principles of equity, justice, and human rights, emphasizing the need for inclusive and context-sensitive knowledge systems. The analysis also prompted a rethinking of traditional development notions, advocating for a holistic view that includes social and environmental well-being. The conclusion stressed the importance of integrating these philosophical dimensions into policymaking to create effective, inclusive strategies for sustainable global progress. Unique Contribution to Theory, Practice and Policy: The Utilitarianism, Deontological Ethics and the Social Contract Theory may be used to anchor future studies on the philosophical analysis of SDGs. The study recommended integrating diverse ethical perspectives into development theories, emphasizing inclusive and participatory approaches in practice, and promoting integrated policy frameworks that align with the holistic nature of the SDGs. It highlighted the need for robust monitoring and evaluation mechanisms, enhanced global cooperation, and the incorporation of sustainability and ethical considerations into educational curricula. These recommendations aimed to ensure that development efforts were economically viable, socially just, and environmentally sustainable, ultimately fostering a more inclusive and effective pursuit of the SDGs.

Poetics of Intracellular and Extracellular Water: A Biophysical Consideration of Black Feminist Thought

Poetics is the articulation of aliveness to the extent that it may be written (Quashie, 2021). It is the approximated space that engages the figuring of one’s existence in relationality. This rhetoric of being and belonging in relationality supposes that individualism is death in a world that opposes life (Quashie, 2021). Aliveness is the possibility that movement might happen, the force of an alive being. When informed by the forces of fear and degradation, one may be faced with a choice to accept or refuse. In the act of refusing, the potential for something more than the world’s divisions hangs in the air. The world is full of fluid existence--being. In the Western scheme of hierarchy and subordination, the categorical devaluation of some beings over others is dictated by the dominant and empowered (Wilkerson, 2020; Wynter, 2003). Poetry poses another way, even the possibility of becoming and undoing (Quashie, 2021). Philosopher Sylvia Wynter suggests that the world needs a new universal way of being, a mode of experiencing in which every form of life is beholden to one another (Wynter & Scott, 2000). Through linguistic loopholes and words of world-making, poetics is the development of theory (Gumbs, 2020). It is an investigation of what is possible and might be.

Contradictions between Capitalism and Sustainable Human Development: Where is the 2030 Agenda Headed?

ABSTRACT This article aims to analyse the basic premises of the theory of sustainable human development as it is based on the 2030 Agenda for Sustainable Development, and contrast it with the theoretical and political proposals of capitalism. With this purpose, in the first place, the work studies the central elements of development theory, as well as the basic premises that support the capitalist model. Secondly, the article compares the essential contradictions between both theoretical proposals, as well as the invisibility of these contradictions in the 2030 Agenda. The article concludes that the foundational ideas of capitalism, as well as the policies derived from these conceptions, are essentially opposed to the theory and practice of sustainable human development and that this is the real limit to advance in the 2030 Agenda.

Sequential Infiltration Synthesis of Al2O3 in PMMA Thin Films: Temperature Investigation by Operando Spectroscopic Ellipsometry.

Sequential infiltration synthesis (SIS) is a scalable and valuable technique for the synthesis of organic-inorganic materials with several potential applications at the industrial level. Despite the increasing interest for this technique, a clear picture of the fundamental physicochemical phenomena governing the SIS process is still missing. In this work, infiltration of Al2O3 into thin poly(methyl methacrylate) (PMMA) films using trimethyl aluminum (TMA) and H2O as precursors is investigated by operando dynamic spectroscopic ellipsometry (SE) analysis. The TMA diffusion coefficient values at temperatures ranging from 70 to 100 °C are determined, and the activation energy for the TMA diffusion process in PMMA is found to be Ea = 2.51 ± 0.03 eV. Additionally, systematic data about reactivity of TMA molecules with the PMMA matrix as a function of temperature are obtained. These results provide important information, paving the way to the development of a comprehensive theory for the modeling of the SIS process.
