When digital mass participation meets citizen deliberation: Combining mini-publics and maxi-publics in climate policy-making

Notwithstanding the rationale and the demand for public participation in climate policies, aggregated perspectives of maxi-publics are often belittled as uninformed, self-interested and short-term focused. The upcoming vogue of climate assemblies, citizen parliaments and other forms of mini-publics is to give citizens a central role in climate policy-making and in some cases to break political impasse. Yet climate mini-publics face challenges in political environments too, such as co-option, favoring expert-opinions and losing touch with the broader public. To remedy such pitfalls, recent papers have argued to combine synchronous deliberations of small groups of citizens with online participation procedures for the larger public. In this article, we report the results of a three-step combination model, where first a mini-public in the region of Súdwest-Fryslân (NL) were given a ‘carte blanche’ to draft the content and the parameters of several related policy alternatives. Second, their proposals where fed into a digital participation tool, the Participatory Value Evaluation (PVE) to consult the wider public. A total of 1,376 (approx. 2% of the inhabitants) expressed their preferences and explained why they favour a dominant role for the municipality and the residents but are reticent about giving the market too big a role. Third, a citizen forum translated the outcomes of the maxi-public into policy recommendations, which were unanimously approved by the municipal council. In this paper, we report our findings of combining mini-and maxi-publics and how actors involved evaluated the strengths and weaknesses of the combination of these two participatory approaches.

Modelling, FEA analysis and Optimization of Mono Composite Leaf Spring Using ANSYS

Conventional leaf spring made up of conventional materials like plain carbon steel are heavy and add weight to vehicle which reduces mileage. This necessitates new material which is light in weight and could provide adequate strength to leaf spring along with higher strain energy absorption to absorb shocks. The current research is intended to study the structural and vibrational characteristics of leaf spring made of P100/6061 Al, P100/AZ 91C Mg and structural steel materials. The investigation is carried out using ANSYS FEA software. The FEA results have shown that P100/AZ/ 91C generated lower stresses as compared to P100/6061 Al and structural steel material. The modal analysis of leaf spring aided to determine mass participation factor and mode shapes corresponding to each frequency.

A Heuristic Approach to Dynamic Stiffness Control

For appropriate and even superior performance yet cost reduction, this work was performed with the aim of weight reduction in the overall design and construction of possibly any machine tools. As far as our literature search is concerned, there does not seem to be much work published regarding successful weight reduction while maintaining performance using mass participation factor (MPF) in the areas of interest of the machine tools. In order to accomplish this task, we started with the ‘bed’ compartment of a CNC system and resorted to using the finite element analysis (FEA) software package and thoughtfully manipulated the available data/parameters until the desired results were obtained. The most important parameters were static stiffness, dynamic stiffness, and damping ratio. On the ‘bed’ of the machines’ compartment currently in production, it was so identified that there was unnecessary material (dead weight), and thus the FEA software was used in order to remove the unnecessary material by iteration. Finally, a new machine was built devoid of the unnecessary material, resulted in 9.3% weight reduction as predicted by the simulation, without sacrificing any accuracy and/or precision in performance.

Mass Atrocities and Their Prevention

Counting conservatively, data show about 100 million mass atrocity-related deaths since 1900. A distinct empirical phenomenon, mass atrocities are events of enormous scale, severity, and brutality, occur in wartime and in peacetime, are geographically widespread, occur with surprising frequency, under various systems of governance, and can be long-lasting in their effects on economic and human development, wellbeing, and wealth, more so when nonfatal physical injuries and mental trauma also are considered. As such, mass atrocities are a major economic concern. Given the multidisciplinary nature of the subject matter, the pertinent conceptual, theoretical, and empirical literatures are voluminous and widely dispersed, and have not been synthesized before from an economics point of view. We address two gaps: a “mass atrocities gap” in the economics literature and an “economics gap” in mass atrocities scholarship. Our goals are, first, to survey and synthesize for economists a broad sweep of literatures on which to base further work in this field and, second, for both economists and noneconomists to learn how economic inquiry contributes to understanding the causes and conduct of mass atrocities and, possibly, to their mitigation and prevention. In drawing on standard, behavioral, identity, social network, and complex systems economics, we find that the big puzzles of the “how” and “why” of mass atrocities, and mass participation therein, are being well addressed. While new research on such topics will be valuable, work should also progress to develop improved prevention approaches. (JEL D72, D74, K38, N40, Z13)

Taking Back Civic Space: Nonviolent Protests and Pushbacks against Autocratic Restrictions in Thailand

The year of 2020 witnessed the eruption of Thailand’s largest and longest-lasting mass demonstrations since the 2014 military putsch. Despite threats of crackdown, protesters leveraged a host of innovative nonviolent actions to reclaim political space that the regime had previously squeezed. This article sheds light on key mechanisms that underpin nonviolent actions’ ability to push back against a trend of shrinking space. We argue that the logic of nonviolent action, tactical and digital creativity, and counteracting repression operates in tandem. First, specific forms of nonviolent action carved out space for popular protest and increased public participation in it despite regime hindrances. Second, particularly tactical and digital creativity sustained this mass participation by reversing some effects of repression. Third, nonviolent responses to this repression encouraged further anti-regime mobilization. We conclude our analysis with some caveats. The Thai case shows that keeping regained space can be difficult.

The Green Movement in Iran: Reformist Roots and Objective

The protests that rocked the streets of Tehran and some other major Iranian cities in 2009, gradually coming to be known collectively as the Green Movement, were triggered after the official announcement of that year’s presidential election result. This article will demonstrate how key features of the Green Movement – including the mass participation of youth, women and university students – were rooted in sociopolitical changes that occurred in Iran in the late 1990s and 2000s. The article argues that the Green Movement should be viewed as a reformist movement which sought to implement certain reforms in Iranian society – an agenda also pursued by its leaders – rather than a revolutionary movement seeking to overthrow the Islamic Republic.

Development of the European Ladybirds Smartphone Application: A Tool for Citizen Science

Wildlife observations submitted by volunteers through citizen science initiatives are increasingly used within research and policy. Ladybirds are popular and charismatic insects, with most species being relatively easy to identify from photographs. Therefore, they are considered an appropriate taxonomic group for engaging people through citizen science initiatives to contribute long-term and large-scale datasets for use in many different contexts. Building on the strengths of a mass participation citizen science survey on ladybirds in the United Kingdom, we have developed a mobile application for ladybird recording and identification across Europe. The main aims of the application are to: (1) compile distribution data for ladybird species throughout Europe, and use this to assess changes in distribution over time; (2) connect and engage people in nature and increase awareness about the diversity and ecological importance of ladybirds. In developing the application we first constructed a database including ladybird species from the United Kingdom, Czech Republic, Slovakia, Italy, Belgium, and Portugal with associated information on relevant morphological features (e.g., size, main color, pronotum pattern) to inform identification. Additionally, the species were assessed on the basis of probability of occurrence within each country which enables users to reduce the number of species to only those with relevance to the location of the recorder. This is amongst the first collaborative citizen science approaches aimed at involving participants across Europe in recording a group of insects. In the near future, we aim to expand the use of the application to all countries in Europe.

Comparative Study of Seismic Acceleration Amplification Models for RC Frame Structures

As the current aspect, the nonstructural components (NSCs) linked with the structures are more affected during the seismic motion. It causes not only loss of the economy but also affected life. The various codal provision has been available for minimizing the damages of primary components, but for NSCs, a minimal requirement is functional. So that more investigation is required for understating the behavior of NSCs during the seismic motion. The research aims to understand the behavior of acceleration demand on NSCs in a building. Structures subjected to inertia forces due to earthquakes experience damage of nonstructural components (NSC). The inertia force acting the NSCs are related to acceleration amplification factor. For obtaining the peak horizontal floor acceleration with respect to tectonic ground motion, these factors are used. In this paper, mathematical models of the acceleration amplification factor defined as the peak floor acceleration with respect to peak ground acceleration, given by previous researchers, has been compared. For this 2,4,6,8 and 10 storey moment-resisting frame models considering 29 ground motion data ranging between 0.1g to 0.2g, is analyzed using linear time history method. The supports of the models are considered fixed. The ETABS software is used for the analysis of the models. To analyses the models, the modal mass participation ratio plays a significant role. ASCE 7-05 defines that the structure should be investigated and designed when the model mass participation ratio is equal to or more than 90 per cent. Based on the results, a comparison of the reported models is made. There is a strong need for further research to refine the models for the realistic prediction of acceleration amplification factor.
