Catalyzing the Commons - Inverting the Participatory Process in the Production of Public Space
Authors:   California College of the Arts, Steinmuller Antje , Falliers Christopher ,   California College of the Arts
Published: March 2022

The role, form, and locus of public space in urban environments has changed. Indoor entertainment spaces often replace the urban exterior as places of collectivity and chance encounter; austerity measures and rapid densification alike are factors in the proliferation of Privately Owned Public Open Spaces(POPOS); and in cities across the globe, the public itself has changed as a consequence of multifaceted migration patterns. At the same time, there has been a widespread resurgence of interest in the ‘urban commons’,understood as collectively appropriating and regulating urban resources. This trend has altered the relationship of citizens to architects in the production of urban collective space. The diversity of stakeholders in traditional public space design has led to complex design and planning processes for architects that offer only intermittent citizen participation in the process of constructing a final outcome.Urban commons projects, in contrast, are based on local citizen initiation, direct negotiation between stakeholders, long-term involvement of citizens, and the evolution of public space over time. In commons projects, the involvement of architects takes on the form of intermittent participation, using acupunctural interventions to catalyze the next steps in the commons’ evolution, thus inverting the role of citizens and architects in the production of public space.
El estudio de la disfunción del cotransportador sodio/bicarbonato electrogénico como causa del desarrollo de la hipertrofia cardíaca
Authors:   , Di Mattia Romina Alejandra
Published: March 2022

Para el correcto funcionamiento de una célula es de vital importancia el mantenimiento de la homeostasis. En particular, en un miocito cardiaco, un descenso del pHi por debajo de 7,2 genera una acidosis que puede impactar de forma perjudicial en sus funciones, afectando tanto la actividad eléctrica como la respuesta contráctil. Existen entonces mecanismos que cumplen el rol de prevenir disfunciones mediante la alcalinización del interior celular: el intercambiador Na+/H+ o NHE1, que cataliza el influjo de un Na+ por cada H+ que extrae del espacio citosólico, y el cotransportador Na+/HCO3- o NBC, que impulsa el co-influjo de un Na+ por una o dos moléculas de HCO3-. En el corazón, el transporte de HCO3- es responsable de al menos el 50% de la regulación de pHi. Actualmente se conocen dos isoformas cardiacas de NBC, una electroneutra (NBCn1 de estequiometría 1Na+/1HCO3-) y una electrogénica (NBCe1 de estequiometría 1Na+/2HCO3-). Ambas se encuentran principalmente en los túbulos-t y promueven el incremento de Na+ intracelular, pero la isoforma electrogénica es más eficiente para lograr el mismo efecto alcalinizante porque ingresa la mitad de Na+ por cada ion HCO3-, en comparación con el NBCn1. La hipertrofia cardiaca (HC) se caracteriza por el engrosamiento de la pared del ventrículo izquierdo y es la respuesta compensatoria a un incremento sostenido de la presión arterial. Las ratas espontáneamente hipertensas (SHR) tienen una predisposición genética al desarrollo de hipertensión sin etiología específica, por lo cual constituyen un buen modelo de HC. En estudios previos del grupo de trabajo se encontró en estas ratas un aumento en la expresión y en la actividad del NBCn1. El NBCe1 se encontraba sobreexpresado en comparación con las ratas Wistar normotróficas pero su actividad estaba disminuida. Un abordaje más exhaustivo del modelo, permitió dilucidar que esta reducción de la actividad se debía a que el NBCe1 se encontraba secuestrado en vesículas intracelulares y por lo tanto no estaba disponible para actuar a nivel de la membrana. Debido a la falta de inhibidores específicos, no fuimos capaces de demostrar si este remodelado funcional es causa o consecuencia del desarrollo de hipertrofia cardiaca. El objetivo general de esta tesis es, por lo tanto, investigar la contribución de la isoforma electrogénica del cotransportador Na+/HCO3- cardíaco (NBCe1) al desarrollo de la hipertrofia cardíaca. Utilizando diferentes modelos experimentales se propone dilucidar la implicancia de la disminución de la función del NBCe1 sobre las alteraciones morfológicas, iónicas y electrofisiológicas que se producen como resultado del desarrollo y evolución de dicha enfermedad. La valoración de la participación del NBCe1 permitirá establecer si la disminución de su función es causa o consecuencia del desarrollo de HC, estableciendo su posible utilidad como blanco terapéutico para el tratamiento de esta patología.
Relaciones Públicas, Comunicación Política y narrativa audiovisual: Spot electoral del Partido Popular en las elecciones a la Asamblea de Madrid de 2021
Authors: Fernández Holgado José Ángel , Puentes-Rivera Iván , Fontenla-Pedreira Julia
Published: March 2022

El Partido Popular de Madrid ante la amenaza de una posible moción de censura y aprovechando la ventaja que le otorgaban a su candidata las encuestas en intención de voto, convocó elecciones anticipadas para el 4 de mayo de 2021, de manera unilateral, rompiendo sorpresivamente con Ciudadanos, su socio de gobierno. El equipo de comunicación del partido Popular de Madrid realizó un vídeo en el que se mostró a la candidata Isabel Díaz Ayuso recorriendo diferentes lugares de la Comunidad de Madrid, en los que la pandemia de la Covid-19 no ha conseguido detener del todo su actividad cotidiana, en gran parte gracias a la firmeza demostrada por la propia presidenta a través de las políticas implementadas en la región. En el presente trabajo se hace un análisis del spot Libertad, incidiendo tanto en la parte formal como en la de contenido. Para lleva a cabo dicha labor se desglosó la pieza audiovisual plano a plano analizando el contenido de los elementos visuales, sonoros y recursos gráficos que las componen. Mediante este análisis se han obtenido los siguientes resultados generales, el vídeo no consigue el objetivo de reforzar la imagen de la candidata popular al ser percibido como poco realista, al estar profundamente manipulado y exageradamente interpretado. También fracasa en la defensa de la ideología liberal al mostrar las bondades de una libertad mal entendida que puede resultar ofensiva para las personas afectadas por el Covid-19, al obviar las consecuencias de la gestión durante la pandemia.

The main characteristics of the insurance market for longevity risk: a literature review
Authors: Starita Maria Grazia
Published: March 2022

Longevity risk is the probability of surviving more than own financial resources. This paper aims to define the characteristics of the insurance market for longevity risk. First, it identifies the aging of the population between the OECD countries and the need for long-term care services (i.e., their quality of life). Second, it tries to summarize the main characteristics of the insurance market for longevity risk from the literature point of view. According to the financial literature, the market to ensure the aging population's long-term needs can be considered a puzzle as there are some constraints from the two sides of the market. From the demand point of view, two issues limit the request for insurance products: the role of the State and misunderstanding about the exposure at risk by the population. At the same time, there are other constraints from the supply point of view: the adverse selection and moral hazard issues that impact the pricing of longevity risk. All these constraints limit the growth of this market. Third, it identifies some suggestions for further investigation in the growing field of financial literature. This paper contributes to the existing literature by identifying the constraints that avoid the insurance market's growth for longevity risk and by remembering some solutions to reassess the role of the welfare state.

Authors: De Marinis Lorenzo , Catania Alessandro , Castoldi Piero , Contestabile Giampiero , Bruschi Paolo , Piotto Massimo , Andriolli Nicola
Published: March 2022

In the modern era of artificial intelligence, increasingly sophisticated artificial neural networks (ANNs) are implemented, which pose challenges in terms of execution speed and power consumption. To tackle this problem, recent research on reduced-precision ANNs opened the possibility to exploit analog hardware for neuromorphic acceleration. In this scenario, photonic-electronic engines are emerging as a short-medium term solution to exploit the high speed and inherent parallelism of optics for linear computations needed in ANN, while resorting to electronic circuitry for signal conditioning and memory storage. In this paper we introduce a precision-scalable integrated photonic-electronic multiply-accumulate neuron, namely PEMAN. The proposed device relies on (i) an analog photonic engine to perform reduced-precision multiplications at high speed and low power, and (ii) an electronic front-end for accumulation and application of the nonlinear activation function by means of a nonlinear encoding in the analog-to-digital converter (ADC). The device, based on the iSiPP50G SOI process for the photonic engine and a commercial 28 nm CMOS process for the electronic front end, has been numerically validated through cosimulations to perform multiply-accumulate operations (MAC). PEMAN exhibits a multiplication accuracy of 6.1 ENOB up to 10 GMAC/s, while it can perform computations up to 56 GMAC/s with a reduced accuracy down to 2.1 ENOB. The device can trade off speed with resolution and power consumption, it outperforms its analog electronics counterparts both in terms of speed and power consumption, and brings substantial improvements also compared to a leading GPU.

Authors: Adedayo Segun , Omoshola Bright , Omoniyi Peter
Published: March 2022

This article analyzed the effect of coconut oil-based cutting fluid with emulsion properties of 5%. The cutting fluid was evaluated by comparing it with conventional cutting fluid (Petroleum Based). Machining temperature at the tool-workpiece interface was measured during straight turning operation on CNC machine at various cutting speeds, depths of cut, and fixed feed rate of 7.5 mm/min for 15 minutes. The Response Surface Methodology (RSM) was also used to determine the machining parameters' effect on each cutting fluid's temperature at the tool-workpiece interface. It was observed that the developed coconut cutting fluid outperformed the other cutting fluids as a coolant at all experimented speeds, with a maximum temperature of 63.5 °C at the working zone as against 90.6 °C observed for conventional cutting fluid and 163.8 °C for dry turning. The viscosity values obtained from the developed cutting fluid between 40 °C and 100 °C show the tendency of the developed cutting fluid to maintain its lubricity at a higher temperature. Depth of cut was also observed to have a significant effect on the temperature at the tool-workpiece interface.

Published: March 2022

The study examined the microstructure and mechanical properties of Al-Mg-Si alloy reinforced with palm kernel shell ash (PKSA) and silicon carbide (SiC). The alloy matrix was reinforced with SiC (2 - 8 wt.%) and PKSA (2 wt.%). The double stir-casting method was used to prepare the hybrid composite. The mechanical properties of the produced samples were evaluated based on ASTM standards.  Identification of phases present in the composite was done using a PANalytical Empyrean diffractometer, while the microstructural characterization was examined using a scanning electron machine with electron dispersive spectrometer attachment. The density values increase as the SiC contents in the composites increase. As the reinforcement particulates increase, the mechanical properties of the reinforced composite improved with hardness value (73 – 85.5 BHN); yield strength (81 – 102 MPa); and ultimate tensile strength (123 – 133 MPa) compared with the matrix alloy of 73 BHN, 79 MPa, and 116 MPa, respectively. However, the percentage elongation and the fracture toughness of the reinforced samples reduced to 34.2 and 40.11%, respectively. The phases identified in the composites were Al, SiO2, Fe3Si, MgO, and SiC.  The synthesized hybrid composites would be applicable as building materials such as aluminium frames and roofing sheets.
Board Diversity Shareholder Suits: Diverging Materiality Tests Under Rules 10B-5 and 14A-9
Authors: Friess John
Published: March 2022

Environmental, social, and governance (ESG) investing has grown significantly as an investment strategy over the past decade, leading to intensified demands among investors for more ESG disclosures from publicly listed companies. Perhaps the most high-profile example of this trend is the recent widespread demand among institutional investors, proxy advisory firms, and exchanges for more disclosure and compliance as it relates to board and workplace diversity. Given these efforts and the signals coming from the SEC that it intends to take a more proactive approach to ESG disclosure and compliance, issuers can expect an environment of more specific and detailed diversity disclosures. These increasingly comprehensive disclosures implicate the anti-fraud provisions of the federal securities laws, particularly Rules 10b-5 and 14a-9. While the Supreme Court has held that the materiality requirement under each of these rules is identical, this note argues that, in the case of securities fraud claims related to diversity disclosures, they require distinct evaluations and lead to different outcomes. Specifically, Rule 14a-9, with its focus on what is important to a reasonable investor’s voting decisions, is more favorable to plaintiffs than Rule 10b-5, which regulates information important to a reasonable investor’s buying and selling decisions. The divergent outcomes are due, in large part, to the combined effects of ownership concentration, passive investing, and the preference among investors for addressing ESG and diversity by voting their shares rather than by selling them. As a result, this note finds that Rule 14a-9 is an increasingly viable option for claims against issuers for false or misleading statements related to board diversity. Consequently, Rule 14a-9 may constitute a mechanism by which plaintiffs can motivate compliance with board diversity standards by making noncompliance too costly.
An adaptation study for the measurement of scientific process skills in gifted students: Diet cola test
Authors: Ülger Bestami Buğra
Published: March 2022

The Fowler Diet Cola Test (DCT) was originally developed to assess the scientific process skills of students in science classrooms. The use of the test is generally suggested for gifted students in science. There are a considerable number of Scientific Process Skills (SPS) tests that the researchers developed for the different student populations. The necessity of a test that measures gifted students’ scientific skills in Turkey is the major reason to conduct this study. This study investigated the reliability and validity of the test for the Turkish context. The test itself contains two scientific problems as Form A and Form B. We examined and resulted in the reliability estimates and translation procedures which are interrater reliability, equivalent forms, and criterion validity. Also, we presented the validity results to show this test can be helpful and suited for gifted students in 5th and 6th-grade science classes. The results suggest that DCT is a suitable instrument for assessing students' science process skills identified as talented in 5th and 6th-grade students.

In an interconnected electrical power system, load frequency control is a most important ancillary service essential for maintaining the electrical system reliability at an adequate level. A Multi-Objective Grey Wolf Optimization (MOGWO) algorithm is introduced for maintaining a balance among exploitation and exploration stages and provides the best value of fitness. During the occurrence of the disturbance in the output of the system the optimization is implemented with Firefly Algorithm (FFA) and MOGWO which is tuned carefully and also the parameters are compared with three-area three-source model of the power system. A Fractional Order Proportional and Derivative (FOPID) controller is a PID controller whose derivative and integral orders are fractional rather than integer. The FOPID controller supports the better stability of the designed model with controlled deviation in frequency and grid tie line power deviations. In this proposed research work, optimal tuning of parameters of various controllers like PI, PID and FOPID in the power system is to regulate frequency in a multi-area multi-source model which is designed with the hydro-thermal-gas generation units. The output performance of the model designed is estimated from simulation results by means of MATLAB-SIMULINK tool. The dynamic performances of the system are studied with 1% or 2% step load perturbation in one Area. Sensitivity analysis reveals that the FFA and MOGWO optimized FOPID controller parameters obtained at nominal condition of loading, size and position of disturbance and system parameters are robust and need not be reset with wide changes in system.The simulation results show the effectiveness of FOPID controller in the presence and the absence of the FF and MOGWO algorithms considered and in that MOGWO algorithm is executed appropriately and it has improved the performance based on metrics such as overshoot, undershoot, and settling time.

Authors:   Department of Electrical Power and Machine Engineering, Faculty of Engineering, Misr University for science and Technology, 6th October, Giza, Egypt., Soliman Hamdy Mohamed
Published: March 2022

The vector control drive system is a very important method to get high dynamic performance. To increase the reliability and decrease the cost of this system, the sensorless speed control is used. Here sensorless speed control conventional model reference adaptive system was studied. It was studied due to have many advantages. Although it has many advantages, but also, it has some drawbacks. These drawbacks an increase in the torque ripples, an increase in distortion of the stator currents, fluxes and motor speed. The aim of this paper is beating the drawbacks of the chosen system through simulation only. Three level inverter with space vector modulation constant switching frequency is used to overcome these drawbacks. To show the effect of the proposed system, it was compared to the conventional system. The conventional system here uses the two-level inverter with space vector modulation. To show the advantages of the constant switching frequency, the three-level inverter was used without keeping the constant switching frequency. The comparison held among the conventional model, the improved model which using the three-level inverter only and proposal model (the three-level inverter which using constant switching frequency). In the conventional model, the reference currents and the estimating currents compared to generate the reference voltage of the space vector modulation. In proposal model, the stator fluxes were estimated and compared to the reference stator fluxes to generate the same voltage of the space vector modulation through keeping the switching time constant. The simulation results proved that importance of the proposed model to improve the drawbacks of the conventional model reference adaptive system.

This paper presents the effects of the waste tire, water content, and relative density on soil dominant frequency using the experimental application. In this study, metal cylindrical molds with a diameter of 30 cm and a height of 50 cm are prepared to understand the effects of these materials. These molds are filled with sand in different relative densities (60% and 80%). Also; the samples are prepared by adding waste tire particles at different rates (0%, 0.5%, 1%, 2%) to this sand for different relative densities and water contents (0%, 5%, 10%, 15%). The soil dominant frequency and H/V amplitude are determined with the microtremor technique by measuring at 60 minutes of measurement on each cylinder using a broadband seismometer. Microtremor data are analyzed by using the Horizontal/Vertical spectral ratio method. As a result of the experiments, it has been observed that the waste tire particles added to the sand affect the H/V amplitude in a decreasing way. It is detected that the most suitable environment is obtained to be 1% waste tire and 0% water content for 60% relative density. Moreover, the most suitable environment has been achieved in 0% water content and 0.5% waste tire ratio for 80% relative density. It has been concluded that the prepared composite material with waste tires may have positive effects on decreasing the earthquake devastating effects.
Designing of High Voltage Cable Bonding with Intelligence Algorithms to Avoid Cable Insulation Faults and Electroshock in High Voltage Lines
Authors:   Electric and Electronic Engineering Department, Faculty of Engineering and Natural Science, Konya Technical University, Konya , Turkey, AKBAL Bahadır
Published: March 2022

The insulation fault is a major problem in high voltage cable lines. The major factors in the insulation faults are harmonic currents and the metal sheath voltage (MV) that occur on the metal sheath of cable. MV and harmonic distortion should be minimized to prevent insulation faults. Thus, sectional solid bonding with different grounding resistance (SSBr) method is developed as a new bonding method for minimizations of harmonic current and MV. Also, SSBr should be optimized by optimized according to minimum MV and harmonic distortion rate of high voltage cable. Inertia weighted particle swarm optimization (iPSO), particle swarm optimization (PSO), genetic algorithm (GA) and differential evolution algorithm (DEA) are used for optimization of SSBr, and three groups the prediction methods are used separately as objective function of the optimization methods to determine minimum MV and harmonic distortion. These groups are neural networks, hybrid neural networks and regression methods. Hybrid neural network with inertia weighted particle swarm optimization (H-iPSO), linear regression and feedforward backpropagation neural network are selected from their groups according to training errors. Solid bonding method is widely used for bonding of high voltage cable, and solid bonding is simulated in this study. When solid bonding is used for bonding of cable, maximum harmonic distortion rate is measured as 8.15 %, and maximum MV is measured as 1086 V. When H-iPSO is used as prediction method, and PSO is used as optimization method, maximum harmonic distortion rate is measured as 5,28 %, and maximum MV is measured as 57 V. Namely, both insulation fault and electroshock can be prevented by the optimized SSBr method.
