German Language Teachers and Dyslexic Students

Dyslexia is a common disorder experienced by many students in Europe and worldwide. It is a specific learning disability, which also generates difficulties in foreign language acquisition. Publications presenting the etiology, pathomechanism, symptoms and types of dyslexia can be found in literature. There are also guidelines for parents and teachers of dyslexic children. This paper attempts to fill a gap in literature addressing teachers of specific school subjects, more specifically German language teachers, who have dyslexic children in their classes. The article points out the difficulties faced by both the teacher and the students. We present a synthetic review of the literature on dyslexia and the current research on the subject, followed by the key laws and regulations in the Polish legal system that relate to the situation of a dyslexic child at school, with particular emphasis on modern language (German) classes. The Polish legal system and the knowledge contained in the most recent literature set the framework for the conduct of educational institutions and indicate the principles of action of professionals, including Germanists, involved in the education of dyslexic students. Symptoms of specific foreign language learning difficulties include, for example, poor development of linguistic functions, difficulties in differentiating sounds and finding sounds in words, problems with dividing words into syllables or distinguishing similar-sounding words, difficulties in assimilating grammatical and spelling rules. Compilation of practical tips with guidelines for the assessment of dyslexic pupils, e.g., the use of descriptive assessment for written work, possible use a computer for written work, providing oral answers to questions from the bench rather than the middle of the classroom, asking simply formulated questions, is most essential for German language teachers. These teachers, as well as teachers of any modern language, should bear in mind the need to use pedagogical, legal and practical knowledge in their work with dyslexic students.

Les poèmes de Mao Zedong : Fleurs du mâle ou sublime prométhéen

Abstract Some sixty authenticated poems written by Mao Zedong were the subject of studies that highlight the relationship between the statesman and his literary talent, through rather socio-political or psychological approaches. The present paper intends to focus on his poetic creation, by scrutinizing from the inside the textual and scriptural tension that animates the process of reappropriation and reinvention in relation to classical Chinese poetry, in particular to the “heroic and free” or fiery style (haofang 豪放). Thematic and rhetorical analyses aim to show how the Promethean sublime nourishes a virile poetics in Mao Zedong’s work and an unusual verbal dynamic, which has the potential to transform conventions into speech, and poetry into a principle of action.

Operationalizing the biocultural perspective part II: A review of biocultural action principles since The Declaration of Belém

In part 1 of our review of the biocultural conservation literature - conducted in 2019 - we utilized a rapid appraisal approach to determine that while the biocultural perspective was born within the action-oriented and Indigenous People and Local Community (IPLC)-Centered Declaration of Belém, the subsequent scientific discussion remained largely in a conceptual holding pattern. In Part 2, we reengage the literature later in time - mid-2021 - and with a more intensive qualitative analysis methodology to pursue the trends we observed and to more deeply perceive and comprehend the operating principles of the most impactful biocultural action research, which we define as research that fulfills the clear prescriptions of the Declaration of Belém. Toward these ends, we develop and utilize a systematic review methodology including thematic analysis, appreciative inquiry, and collaborative analysis. Our findings not only show an increasing concentration of action-orientation in the emerging literature, but identify and increase comprehension of the core operating principles for biocultural action. We determine that biocultural studies adhered to the following principles: 1) honor IPLC place attachment; 2) rigorously engage with IPLC's; 3) valorize cultural survival and continuity; 4) invert power dynamics; and 5) cultivate new insights. Our results represent a one-of-a-kind diagnostic on the fulfillment of the Declaration of Belém's prescriptions in conservation scholarship and practice, as well as a roadmap for practicing scholars and policy-makers intent on guaranteeing IPLC environmental leadership. These newly forged resources further point the way toward understanding and operationalizing the biocultural perspective as a strategic vision.

Sudden-Onset Disaster Mass-Casualty Incident Response: A Modified Delphi Study on Triage, Prehospital Life Support, and Processes.

The application and provision of prehospital care in disasters and mass-casualty incident response in Europe is currently being explored for opportunities to improve practice. The objective of this translational science study was to align common principles of approach and action and to identify how technology can assist and enhance response. To achieve this objective, the application of a modified Delphi methodology study based on statements derived from key findings of a scoping review was undertaken. This resulted in 18 triage, eight life support and damage control interventions, and 23 process consensus statements. These findings will be utilized in the development of evidence-based prehospital mass-casualty incident response tools and guidelines.

Renormalizability of nonlocal quantum gravity coupled to matter

We extensively study the ultraviolet quantum properties of a nonlocal action for gravity nonminimally coupled to matter. The theory unifies matter and gravity in an action principle such that all the classical solutions of Einstein’s theory coupled to matter are also solutions of the nonlocal theory. At the quantum level, we show that the theory is power-counting super-renormalizable in even dimensions and finite in odd dimensions. A simple extension of the model compatible with the above properties is finite also in even dimensions.

Spiritual Knowledge Management: Practical Wisdom and Faith-at-Work Brought to Life

Integrating knowledge management, faith-at-work, and phronetic workplace domains, this paper presents phronesis, or practical wisdom, and faith-at-work (FAW) based on theoretical principles of moral actions and character virtues and real-life examples of FAW practices such as thoughts, behaviors, and feelings, bringing to life the practically-wise company. Answering a call to investigate phronesis in the workplace to understand how the individual level of practical wisdom spreads throughout the company achieving a practically-wise company this paper refines one segment of Long’s (2022) research findings in Faith at Work: People, Places, Practices, and Tools from the spiritual knowledge management (SKM) domain perspective. These FAW experiences equate to spiritual knowledge and spiritual intelligence in motion while supporting human resource development strategies for employee flourishment. The methodology is empirical phenomenology presupposing theory for the relevant phenomena. The Long (2022) study adds a deeper understanding that sharpens and supports SKM by extracting specific findings and implications of the integration of practical wisdom, moral actions, character virtues, and FAW practices - intersections that enlighten organizations to create desirable value.

A Sociolinguistic Study of Shop Names in Limbe

This study investigates the linguistic characteristics used in shop names in Limbe. It examines the structures of shop names and identifies the motivation for their choices by shop owners. It also examines the competence of shop owners in the languages used in shop names. This study makes use of two theories which are the structuration principles by Ben-Rafael (2009) and Reh’s (2004) taxonomy of multilingual information. The structuration principle is based on four principles of social action which are presentation of self, good reason, power relations and collective identity. These principles help businessmen to make a good language choice which promotes their businesses. Reh’s multilingual information is based on four multilingual arrangements which are duplicating, fragmentary, overlap and complementarity. This theory helps to analyse the language used on shop names and also the language situation in the community. A mixed method of research design is used in the study. Qualitative data is analysed thematically. The findings show that there is multilingualism in shop names in Limbe, and that shop owners make use of six speech forms. Moreover, shop owners are motivated by several reasons to choose certain languages on shop names.

Расчет системы амортизации шасси пассажирского самолета при ударном нагружении

The paper considers the shock absorption system of an advanced domestic mainline passenger aircraft, which includes oleo-pneumatic shock absorbers and wheels equipped with the pneumatic tires. Nonlinear mathematical models of single-active and two-active oleo-pneumatic shock absorbers of telescopic landing gear supports are proposed. The models take into account the process of polytropic gas compression, the forces of hydraulic resistance to the working fluid flow and the forces of dry friction arising in the system moving parts. To describe the vertical compression reaction of the pneumatic tires, the V.L. Biderman structural model was introduced, which parameters were determined by test results using the least squares method. Motion equations of the landing gear elements were obtained by the analytical mechanics methods involving the Ostrogradsky --- Hamilton variational principle of least action. Constraints imposed on the system were introduced using the penalty functions method. The problem statement of carrying out virtual computational experiments on the landing gear dvops was considered. In a wide range of the impact energies, models of shock absorbers of a passenger aircraft landing gear were validated, for which time realizations of the system state vector were determined, and areas of hysteresis loops of the shock absorber load characteristics were evaluated by the numerical integration. Satisfactory compliance of the results of simulated characteristics of the natural objects was shown. The obtained results could be used to improve the absorption quality criteria by numerical optimization methods, calculate the landing impacts and analyze the aircraft oscillations when moving on the runway

Y-ring’s mechanical behavior during sealing cap’s assembly process based on the pressure core sampling for seafloor drill

In order to expand the application of seafloor drill in the field of natural gas hydrate exploration, a pressure core sampling technical scheme suitable for seafloor drill operating conditions is proposed. The assembly action principle of sealing cap in the scheme is introduced. The factors affecting the sealing reliability during the assembly of the sealing cap are analyzed. A geometric model of the sealing structure is established. The variation regular of the max von Mises stress is discussed during the assembly process. The relationship between the assembly parameters and the maximum von Mises stress is clarified. The parameters optimization scheme is proposed and verified by experiments. The results show that: the Y-ring’s maximum von Mises stress variation trend has five stages and the maximum von Mises stress produces peak stress in the rising stage, excessive interference and friction factor make the peak appear in the fluctuation stage in advance, the lead angle within 10°–30° has little effect on the maximum von Mises stress peak value, the axial displacement speed affect the growth rate and amplitude of the maximum von Mises stress curve, the drilling tool’s pressure loss ratio is within 8% under the 10–40 MPa after 6 h.

Experimental study of the effect of mechanical vibration and water velocity on bubble management in PEM electrolysis cell

The anode of a proton exchange membrane electrolysis cell (PEMEC) has a complex two-phase flow. Excessive gas concentrations tend to build up on the catalyst layer (CL) surface and inside the porous transport layers (PTLs), inhibiting electrolytic reactions from occurring. Therefore, efficient bubble management methods are required. In this paper, the principle of actions and the effect of mechanical vibration and water velocity as methods of bubble management are investigated. PEMEC bubble kinetic and two-phase flow performance were investigated using high-speed optical imaging at different amplitudes, frequencies and water velocities, and the results were correlated with electrochemical performance. The results show that the vertical sinusoidal vibration can cause cyclic compression of the PTL by the ribs, which promote the discharge of the blocked gas into the flow channel. This effect can be enhanced by increasing the amplitude of the vibration. During vibration, the inertia of the water causes the large bubbles to break up into smaller bubbles and can generate longitudinal shear forces that can promote the bubbles to detach and move. Increasing the frequency can enhance this effect by shortening the period of the action. However, the vertical sinusoidal vibration does not promote the discharge of air bubbles from the flow channel out of the cell, in which the thrust and lateral shear provided by water flow is necessary. Increasing the water velocity can also generate more bubble flow. The combination of vibration and high water velocity can significantly reduce the gas concentration in the cell. Polarization data shows a 7.2% reduction in cell polarization under the experimental conditions (80 mL/min, 1.5 mm, 150 Hz) compared to the normal state. The results of this study can provide theoretical basis and experimental data for the study of bubble management methods, optimization of working conditions and improvement of operating efficiency of PEMEC.

Quantum chaos in 2D gravity

We present a quantitative and fully non-perturbative description of the ergodic phase of quantum chaos in the setting of two-dimensional gravity. To this end we describe the doubly non-perturbative completion of semiclassical 2D gravity in terms of its associated universe field theory. The guiding principle of our analysis is a flavor-matrix theory (fMT) description of the ergodic phase of holographic gravity, which exhibits \mathrm{U}(n|n)U(n|n) causal symmetry breaking and restoration. JT gravity and its 2D-gravity cousins alone do not realize an action principle with causal symmetry, however we demonstrate that their universe field theory, the Kodaira-Spencer (KS) theory of gravity, does. After directly deriving the fMT from brane-antibrane correlators in KS theory, we show that causal symmetry breaking and restoration can be understood geometrically in terms of different (topological) D-brane vacua. We interpret our results in terms of an open-closed string duality between holomorphic Chern-Simons theory and its closed-string equivalent, the KS theory of gravity. Emphasis will be put on relating these geometric principles to the characteristic spectral correlations of the quantum ergodic phase.

Integrating knowledge and action: learnings from an implementation program for food security and food sovereignty with First Nations communities within Canada

BackgroundCollaborative approaches to knowledge translation (KT) are important for advancing community-engaged research. However, there is a need for examples of participatory approaches that have effectively supported public health research, program development, and implementation with First Nations communities. To strengthen KT with communities, we proposed a set of guiding principles for participatory planning and action for local food system change. Principles emerged from a cross-community analysis of Learning Circles: Local Healthy Food to School (LC:LHF2S) a participatory program (2015–2019) for Indigenous food system action. The objective was to identify guiding principles for participatory planning and action from key learnings and successes on scaling-up of the Learning Circles (LC) model vertically in Haida Nation, British Columbia (BC), and horizontally in three distinct community contexts: Gitxsan Nation, Hazelton /Upper Skeena, BC; Ministikwan Lake. The application of these principles is discussed in the context of our ongoing partnership with Williams Treaties First Nations to support community planning to enhance food security and sovereignty.MethodsA cross-community thematic analysis was conducted and guided by an implementation science framework, Foster-Fishman and Watson’s (2012) ABLe Change Framework, to identify key learnings and successes from adapting the LC approach. Information gathered from interviews (n = 55) and meeting reports (n = 37) was thematically analyzed to inform the development of guiding principles. Community sense-making of findings informed applicability in a new community context embarking on food systems work.ResultsEmergent guiding principles for participatory food system planning and action are described within four main areas: (1) create safe and ethical spaces for dialog by establishing trust and commitment from the ground up, (2) understand the context for change through community engagement, (3) foster relationships to strengthen and sustain impact, and (4) reflect and embrace program flexibility to integrate learnings.ConclusionsEmergent principles offer guidance to supporting Indigenous community-led research and mobilization of knowledge into action. Principles are intended to support researchers and health system administrators with taking a collaborative approach that fosters relationships and integration of community leadership, knowledge, and action for food system change. Application of principles with implementation frameworks can strengthen KT in Indigenous contexts by incorporating community protocols and perspectives in support of Indigenous self-determined priorities.

Choosing and avoiding:

The pursuit of understanding the phýsis (physiology) is a never-ending philosophical activity that leads to a praxis (pragmateía) which manifests itself in every choice (haíresin) and in every rejection (phygèn) made by man as he acts in agreement to the knowledge he has of the nature of things. To choose and to reject is only possible for those who place the principle of action in themselves (autarkeía). Thus, Epicurus ethics is grounded on the understanding of the phýsis, which means, in this context, to rid oneself of ignorance and unwarranted (irrational) fears; misbeliefs and opinions accepted and disseminated by the multitude of the senseless. It is posited here that the relation between physiologia and ethics assures coherence to Epicurus’ philosophical praxis. The present paper’s objective is to make explicit the meaning the term autarkeía acquires in Epicurus’ thought in the context of Letter of Epicurus to Menoeceus, Principal Doctrines, and Vatican Sayings. Freedom (eleutheria) shows itself thru the ongoing exercise of choosing what is desired and rejecting what is harmful; that is, freedom is only possible thru a conduct based on self-sufficiency. Knowledge realizes itself thru action; the same is true for ignorance.

Microwave assisted pyrolysis of biomass feedstock fundamentals and the effect of process parameters - A Review

Globally, biomass usage as a supply of non-depletable resources materials used in the production of energy at their rawest state is an issue. Pyrolysis is a method of thermally treating biomass that as a consequence in the formation of liquid, products, both solid and gaseous. Elevated heating is required to transform the complicated composition of the biomass’s underlying structure matrix into usable products. Heating with a microwave oven has the potential to become a competitive option. to more traditional methods of heating. Owing to its ease of operation and rapid heating rate, it has recently been widely employed in pyrolysis. The goals of this research are to found the principles of MW-assisted pyrolysis action and to examine some critical issues characteristics of operation that have an influence on the yield of a product. This procedure appears to be governed by a number of operational factors for instance, microwave power and temperature degree, the addition of microwave absorbers and their concentration, initial relative humidity, primary sweep gas flow rate/time spent in residence.

Neoclassical models of charged particles

Classical electrodynamics (CED) has achieved great success in its domain of application, but despite this success, it has remained a theory that lacks complete self-consistency. It is worthwhile trying to make CED a self-consistent theory, because many important phenomena lie within its scope, and because modern field theories have been modelled on it. Alternative approaches to CED might help finding a definite formulation, and they might also lead to the prediction of new phenomena. Here we report two main results. The first one derives from standard CED. It is shown that the motion of a charged particle is ruled not only by the Lorentz equation, but also by equations that are formally identical to Maxwell equations. The latter hold for a velocity field and follow as a strict logical consequence of Hamilton’s action principle for a single particle. We construct a tensor with the velocity field in the same way as the electromagnetic tensor is constructed with the four potential. The two tensors are shown to be proportional to one another. As a consequence, and without leaving the realm of standard CED, one can envision new phenomena for a charged particle, which parallel those involving electromagnetic fields. The second result refers to a field-free approach to CED. This approach confirms the simultaneous validity of Maxwell-like and Lorentz equations as rulers of charged particle motion.

Sustainable electronic textiles towards scalable commercialization.

Textiles represent a fundamental material format that is extensively integrated into our everyday lives. The quest for more versatile and body-compatible wearable electronics has led to the rise of electronic textiles (e-textiles). By enhancing textiles with electronic functionalities, e-textiles define a new frontier of wearable platforms for human augmentation. To realize the transformational impact of wearable e-textiles, materials innovations can pave the way for effective user adoption and the creation of a sustainable circular economy. We propose a repair, recycle, replacement and reduction circular e-textile paradigm. We envisage a systematic design framework embodying material selection and biofabrication concepts that can unify environmental friendliness, market viability, supply-chain resilience and user experience quality. This framework establishes a set of actionable principles for the industrialization and commercialization of future sustainable e-textile products.

Geometric and physical interpretation of the action principle

We give a geometric interpretation for the principle of stationary action in classical Lagrangian particle mechanics. In a nutshell, the difference of the action along a path and its variation effectively “counts” the possible evolutions that “go through” the area enclosed. If the path corresponds to a possible evolution, all neighbouring evolutions will be parallel, making them tangent to the area enclosed by the path and its variation, thus yielding a stationary action. This treatment gives a full physical account of the geometry of both Hamiltonian and Lagrangian mechanics which is founded on three assumptions: determinism and reversible evolution, independence of the degrees of freedom and equivalence between kinematics and dynamics. The logical equivalence between the three assumptions and the principle of stationary action leads to a much cleaner conceptual understanding.

Systemic Approach to Entrepreneurial Identity and Its Educational Projection

Although it has acquired an extraordinary social diffusion, entrepreneurial education has a certain lack of definition associated with its conceptualisation and meaning. It seems clear that entrepreneurial education is linked to the economic sphere, but it is not limited to the productive sector. The idea of entrepreneurial education has been progressively enriched, being linked to the development of skills for personal growth and social progress. Further clarification of the meaning and scope of entrepreneurial education is, therefore, needed. Thus, it is relevant to analyse entrepreneurial identity in the context of personal identity via the theoretical–explanatory investigation of a model developed in two phases. A critical analysis leads us to study the different factors that intervene in the configuration of this identity in an attempt to construct a systemic map of entrepreneurial action. Between the private and the public, entrepreneurs seek new ways of facing the challenges of our times, trying to find new ways of regenerating the links between individuals and institutions and with society in general. In this sense, we show how entrepreneurial educational ecosystems acquire relevance insofar as they consider the subject as the principle of action rather than merely the result of various contextual factors.
