Recovery for Resilience: Exploring the Disconnect Between Collaborative Planning and Project Implementation in Post-Hurricane Sandy New York City

Collaborative and participatory planning processes that are interactive, thoughtful, and efficient have become increasingly important elements of post-disaster recovery. Meanwhile, rapid action remains critically important to quickly restore destroyed urban systems, but creating long-term resilience demands new ideas that are also implementable. These various tensions create a daunting paradox, and while many communities have attempted to use collaborative planning approaches in recovery, useful assessments and guidance on collaborative recovery planning is sparse. To better understand the nuances of a collaborative recovery, we document and evaluate the effectiveness of the collaborative processes behind the planning of the ESCR resilience project, initiated as BIG U in New York City, which emphasizes community participation and collaborative decision-making. The project is unique because of its innovative and interactive multi-stakeholder processes. The authors have studied the case longitudinally over the past decade, using a variety of research methods to gather relevant information. The ESCR collaborative efforts suggest that, first, there is a disconnect in the dominant rationalities behind climate resilience efforts between the planning and implementation phases. Second, given the disconnect between the planning and implementation phases, collaborative efforts must be refined to remain relevant in the implementation phase. Third, even after project implementation, there are different types of rationality employed, and thus varying levels of satisfaction, depending on the benefits that participants receive. While planners must recognize the disconnect between collaborative planning and project implementation and seek ways to mitigate any abrupt shifts, we conclude that collaborative approaches to recovery planning can be effective and manageable, even in unique recovery situations.

Chaotification and chaos control of q-homographic map.

This paper concerns the dynamical study of the q-deformed homographic map, namely, the q-homographic map, where q-deformation is introduced by Jagannathan and Sinha with the inspiration from Tsalli's q-exponential function. We analyze the q-homographic map by computing its basic nonlinear dynamics, bifurcation analysis, and topological entropy. We use the notion of a false derivative and the generalized Lambert W function of the rational type to estimate the upper bound on the number of fixed points of the q-homographic map. Furthermore, we discuss chaotification of the q-deformed map to enhance its complexity, which consists of adding the remainder of multiple scaling of the map's value for the next generation using the multiple remainder operator. The chaotified q-homographic map shows high complexity and the presence of robust chaos, which have been theoretically and graphically analyzed using various dynamical techniques. Moreover, to control the period-doubling bifurcations and chaos in the q-homographic map, we use the feedback control technique. The theoretical discussion of chaos control is illustrated by numerical simulations.

Potential of soybean-velvet bean combination tempe in improving cognitive function

Velvet bean is a native Indonesian legume containing L-dopa, yet it remains underutilized. The aim of this study was to analyze the effects of different types of tempe (soybean, velvet bean, and their combination) on cognitive function, brain histology, dopamine levels, and serum β-amyloid in rats, as well as to identify the parameters most influencing cognitive function, including brain mass and volume, hippocampal neuron count, and dopamine and β-amyloid levels. An experimental study was conducted using a completely randomized design with one factor: the protein source of diet. Five rat groups were included based on protein sources: non-protein, casein control, soybean tempe flour, velvet bean tempe flour, and a combination of soybean and velvet bean tempe flour. This study examined cognitive performance by measuring maze completion time, while brain mass and volume, hippocampus histology for neuron cell counts in the dentate gyrus section, cornu ammonis 1 (CA1), and cornu ammonis 3 (CA3), brain dopamine and β-amyloid serum levels were measured after eight weeks of intervention. Our data indicated that rats deprived of protein had significantly slower maze completion times (p<0.001), underscoring the importance of protein in cognitive processes. Rats treated with non-protein rations had significantly lighter brain masses (p<0.001) than other treatments. Histological analysis of the hippocampus showed that the three types of tempe rations helped maintain the number and density of neuron cells in the dentate gyrus and CA3 of the hippocampus. Additionally, the protein in the ration could increase dopamine levels and suppress serum β-amyloid levels. There was a strong correlation between brain volume and neuron cell density in the dentate gyrus section of the hippocampus with cognitive function. These results highlight the promising role of combination tempe in increasing cognitive function, brain mass and volume, dopamine levels, and suppressing serum β-amyloid.

A-optimal experimental designs for Michaelis – Menten model

Kinetics of simple and complex kinetic reactions is usually described by exponential and rational models. The fractional rational models include the well-known Michaelis – Menten model of enzymatic kinetics. In the presented article A-optimal designs are proposed for the Michaelis – Menten model. The elimination method used to construct A-optimal designs, allowed us to determine the nodes and weights of A-optimal designs separately and thereby extend this approach to other criteria and models of the rational type. It is shown that the nodes of A-optimal designs determined by this method are the roots of the 4th degree algebraic equation with coefficients depending on the model parameters. If the nodes of the A-optimal design are already known, then the weights of the corresponding nodes are determined analytically by the Pukelsheim formula. The properties of the roots as well as the properties of the nodes of A-optimal designs were studied using the Sturm system constructed in the general form for the resulting equation. It is shown that with a certain combination of parameters of the Michaelis – Menten model, the degree of the resulting algebraic equation is reduced to three. A partition of the set of values of the parameters of the Michaelis – Menten model into two subsets has been found. In one of them, the A-optimal design is determined uniquely, whereas for the other one it is necessary to select the optimal node from two possible options. It is revealed that the degree of the algebraic equation is equal to three for points belonging to the curve which is the common boundary of the indicated subsets. Corresponding numerical examples are given to illustrate the results obtained.

Investigating fractal fractional PDEs, electric circuits, and integral inclusions via (ψ,ϕ)-rational type contractions

The fixed point theory has been generalized mainly in two directions. One is the extension of the spaces, and the other is relaxing and generalizing the contractions.

For the reliability of the established results, examples and applications to the system of integral inclusions and system of integral equations are presented.

Холистическая антропология А.Л. Чижевского в контексте научного и религиозного мировоззрения

The article is devoted to the holistic views of A.L. Chizhevsky on human; fea­tures of their reflection in the philosophical and scientific works of the thinker, as well as in his poetry, are revealed; scientific and religious aspects of the scien­tist’s holistic anthropology are investigated. Analysis of the holistic world­view presented in the metaphysical work “The main beginning of the universe. Cosmic system. Problems”, allows us to state that the holistic approach to the human by Chizhevsky the philosopher is based on his conviction in the impact of the uni­versal principle of circulation on a single electric substrate. A study of the scien­tific works of one of the founders of space natural science suggests that the holistic anthropology reflected in them is based on specific laws that demonstrate human dependence on the environment (solar activity and ionized air). The Chizhevsky-poet forms the reader’s idea of the closest connection between micro- and macrocosm, about the cosmicity of a human being by using vivid images, with­out references to determinism; nevertheless, the anthropocosmic poems of “Leo­nardo da Vinci of the 20th century” are thematically related to his scientific re­search. The relevance of A.L. Chizhevsky’s holistic anthropology to the concept of global evolutionism and the post-classical type of scientific rationality is shown

Мифические детерминанты политического (Политический проект Платона)

The article is devoted to the explication of the mythological determinants of Plato’s political doctrine. The author raises the question about those axiomatic propositions that underlie the political philosophy of the ancient Greek thinker: what is it, the rudiments of mythical consciousness or the rationality of the nascent philosophical logos? The article shows that there are two opposite answers to this question. One is associated with the tradition of conceptualizing myth as fiction and fantasy (Georg Hegel, Auguste Comte, Feokhari Kessidy), the other with the understanding of myth as a special type of rationality underlying a certain ontological reality (Friedrich Schelling, Alexey Losev, Kurt Huebner). The author shows that modern Platonists are increasingly inclined to the second approach and consider myth as an indispensable element of Plato’s philosophy as such. The central element of his system, the doctrine of ideas, is genetically linked to classical mythology. Plato’s ideas are rationalized supernatural entities, divine substances. This understanding finds comprehensive manifestation in Plato’s political project. The peace of a self-identified being is the ideal of a perfect polis. Justice, on the other hand, is conformity to one’s nature i.e., ultimately, conformity to the divine substance expressed in the idea. Thus, the author concludes, justice in Plato’s project is primarily not a social or political

Segmentation of Chinese consumer preference for wine extrinsic attributes based on stratification and weighted clustering algorithm

Chinese consumers are unfamiliar with the sensory attributes of wine and often pay more attention to the extrinsic attributes of wine that can most directly present information. Therefore, it is crucial to study consumer preferences for extrinsic attributes. This paper proposes a consumer segmentation method based on stratification and weighted clustering algorithm, leveraging data from an anonymous online survey (N = 3179). The AFR model is constructed based on the RFM model to segment wine consumers from the perspective of customer value. This model removes Monetary indicator and adds a new indicator Amount to eliminate multicollinearity caused by the Frequency and Monetary indicators of RFM model. In addition, factor analysis is used to assign weights to clustering indicators, addressing the problems of unequal weighting and strong correlation among the indicators. This allows for a simple, efficient, and precise segmentation of wine consumers at different levels. The method proposed in this article segments consumers into two layers and six categories: the potential layer includes product-oriented type, amorphous type, and cheap-fine type, while the mature layer comprises the rational type, reputation-price type and random type. This research will provide wine producers and distributors with a simple and efficient basis for production and marketing decision-making. Additionally, it can serve as a reference for consumer segmentation in food and other fields.

Rational homotopy type and nilpotency of mapping spaces between Quaternionic projective spaces

The rational homotopy type of a mapping space is a way to describe the structure of the space using the algebra of its homotopy groups and the differential graded algebra of its cochains. An L∞-model is a graded Lie algebra with a family of higher-order brackets satisfying the generalized Jacobi identity and antisymmetry. It can be used to study the rational homotopy type of a space. The nilpotency index of an L∞-model is useful in understanding a space's algebraic structure. In this paper, we compute the rational homotopy type of the component of some mapping spaces between projective spaces and determine the nilpotency index of corresponding L∞-models.

On Certain Fixed Points for (α,φ,F)-Contraction on S_b- Metric Spaces with Applications

Methods: with the help of α- admisible mapping, (φ, F)-contraction, α type F -contraction and (α.φ,F)-contraction we have fixed point findings in complete S_b-metric spaces. Results: we obtained unique fixed point results via (α,φ,F) contractive type for self mapping in complete S_b-MS. Conclusions: In this article, Contractive mappings of the (α,φ,F) type are used to show certain fixedpoint results in the context of S_b-MS, along with appropriate example that illustrate the key findings. Appications to integral equations and homotopy are also offered.

A Revised Fuzzy Differential Equations Using Weakly Compatible Self-Mappings in Revised Fuzzy Metric Spaces

In this paper, we demonstrated certain coincidence point and Common Fixed Point [briefly, CFP] findings under the rational type weakly compatible revised fuzzy-contraction conditions in full Revised Fuzzy Metric spaces [briefly, RFMSs] utilizing the "triangular property of revised fuzzy metric" with examples in this work. We also provided Revised fuzzy differential equations [briefly, RFDEs] as an application and demonstrated that the solution of the RFDEs has a unique CFP of the integral operators B,C and g. This new path of weakly-compatible Revised fuzzy-contraction with the use of RFDEs in RFM space will be crucial. With different sorts of weakly-compatible Revised fuzzy contraction conditions for self-mappings and different forms of differential equations in the context of RFMSs, this approach may be expanded and developed in diverse directions.

Calculation of the main operational characteristics of a tethered high-altitude ship-based system

Objectives. Currently, UAVs are actively used in many military and civilian fields such as object surveillance, telecommunications, radar, photography, video recording, and mapping, etc. The main disadvantage of autonomous UAVs is their limited operating time. The long-term operation of UAVs on ships can be ensured by tethered high-altitude systems in which the power supply of engines and equipment is provided from the onboard energy source through a thin cable tether. This paper aims to select and justify the appearance of such system, as well as to calculate the required performance characteristics.Methods. The study used methods of systemic and functional analysis of tethered system parameters, as well as methods and models of the theory of relations and measurement.Results. The issues of design and implementation of new generation tethered high-altitude ship-based systems were considered. A rational type of aerodynamic design for unmanned aerial vehicles was determined based on existing tethered platforms. The optimal architecture of the tethered system was defined and justified. The paper presents the appearance and solution for placement onboard the ship, and describes its operation. The main initial parameters for designing high-altitude systems such as take-off weight, optimal lift altitude, maximum power required for operation, structure of the energy transfer system, as well as deployment and lift time to the design altitude were selected and calculated.Conclusions. The methodology for calculating the necessary characteristics described in the paper can be used for developing and evaluating tethered high-altitude systems. These systems are capable of performing a wide range of tasks, without requiring a separate storage and launch location, which is especially important in the ship environment. The system presented herein possesses significant advantages over well-known analogues.

Ariadne's Thread Metacognition for emancipatory rationality in education

Emancipatory rationality in education empowers individuals and promotes social justice.Metacognition and critical thinking play vital roles in supporting this approach by encouraging learners and professionals to reflect on their thinking processes, question assumptions, and develop the ability to engage critically with information. The research presented in this paper falls within the action research framework, which provides for theinvestigation to be conducted in the field based on close collaboration between researchers and practitioners. Action research aims to generate improvement and change in the context in which it is implemented. The roots of this approach can be found in Dewey’s criticism of the traditional separation of knowledge and action and in Freire’s idea of conscientization, the process of developing critical awareness through reflection and action. In their view, learning depends upon uncovering real problems and actual needs. Starting from four criticalincidents, the paper demonstrates how reflective practices based on metacognition can be used to train education professionals. Metacognitive work is essential for analyzing problems and responsibilities and identifying any distortions preventing educational action from responding effectively to people's needs. When faced with an educational problem, the professional needs to be able to use two forms of rationality: heuristic-reflective andemancipatory. The first type of rationality guides through the investigation of the experience to build the necessary knowledge to interpret and manage it. The second makes the educator an agent of transformation and change.

Some notes on spaces realized as classifying spaces

In this work, we are concerned with the realization of spaces up to rational homotopy as classifying spaces. In this paper, we first show that a class of rank-two rational spaces cannot be realized up to rational homotopy as the classifying space of any n-connected and π-finite space for n≥1. We also show that the Eilenberg-Mac Lane space K(Qr,n)(r≥2,n≥2) can be realized up to rational homotopy as the classifying space of a simply connected and elliptic space X if and only if X has the rational homotopy type of ∏rSn−1 with n even.
