Abstract

Uncovering the public discourse on hydrogen energy is essential for understanding public behaviour and the evolving nature of conversations over time and across different regions. This paper presents a comprehensive analysis of a large multilingual dataset pertaining to hydrogen energy collected from Twitter spanning a decade (2013–2022) using selected keywords. The analysis aims to explore various aspects, including the temporal and spatial dimensions of the discourse, factors influencing Twitter engagement, user engagement patterns, and the interpretation of conversations through hashtags and ngrams. By delving into these aspects, this study offers valuable insights into the dynamics of public discourse surrounding hydrogen energy and the perceptions of social media users.

Abstract

To accelerate the energy transition and achieve the needed large-scale transformation to address climate change, different barriers including lock-ins and path dependencies, incumbent power structures and changing individual and collective norms, values, and behaviors around energy need to be addressed. In the face of these challenges, citizens are beginning to play a bigger role in the transformation of the energy system. For example, they are becoming prosumers (energy consumers who also produce energy) and are increasingly engaging in collective energy actions, including taking part in energy communities. In the latter instance, collective investment and consumption decisions are made together, and norms, understanding and behavior towards energy are shaped collectively. To better understand the roles that individuals and groups can play in confronting the challenges of the energy transition, we make use of and adapt Ostrom’s socio-ecological systems (SES) framework to analyze past examples of collective actions and to delve deeper into the causes and catalysts of collective actions. We show how this framework can be used to analyze collective actions across time and contexts, focusing on connecting individual and group behavior with changing societal norms and the corresponding barriers to change. By applying the adapted SES framework as a lens to analyze historical examples of collective actions that have resulted in a widespread transformation in social norms and structures, we identify similarities and differences between these case studies and the current energy transition. Confronting incumbents and the challenge of changing social norms and behaviors are among the similarities, but the specific tactics used to limit incumbents’ powers and the actions taken to influence the norms and behaviors differ. Lastly, we determine the key actors that influenced social and behavioral change, as one of the main outcomes of the analysis.

Abstract

Jean Blondel made many lasting contributions toward comparative politics, not least in his classification of party systems in Western democracies. Yet during the 5 decades since Blondel’s original contribution, party competition has been transformed by multiple developments, including changes in the grassroots electorate, as intermediary organizations connecting citizens and the state, and at the apex in legislatures and government. Does Blondel’s typology of party systems remain relevant today—or does it require substantial revision? And, does party system fragmentation predict ideological polarization? Part I sets out the theoretical framework. Part II compares trends from 1960 to 2020 in party system fragmentation in a wide range of democracies, measured by the effective number of parties in the electorate and in parliament. Not surprisingly, the effective number of electoral parties (ENEP) has generally grown in each country across Western democracies. This does not imply, however, that party systems are necessarily more polarized ideologically. Part III examines polarization in party systems across Western democracies, measured by standard deviations around the mean of several ideological values and issue positions in each country. The findings suggest that party system fractionalization and polarization should be treated as two distinct and unrelated dimensions of party competition. The conclusion reflects on the broader implications of the findings for understanding party polarization and threats of backsliding in democratic states.

Abstract

In this paper, we situate our computational approach to philosophy relative to other digital humanities and computational social science practices, based on reflections stemming from our research on the PolyGraphs project in social epistemology. We begin by describing PolyGraphs. An interdisciplinary project funded by the Academies (BA, RS, and RAEng) and the Leverhulme Trust, it uses philosophical simulations (Mayo-Wilson and Zollman, 2021) to study how ignorance prevails in networks of inquiring rational agents. We deploy models developed in economics (Bala and Goyal, 1998), and refined in philosophy (O’Connor and Weatherall, 2018; Zollman, 2007), to simulate communities of agents engaged in inquiry, who generate evidence relevant to the topic of their investigation and share it with their neighbors, updating their beliefs on the evidence available to them. We report some novel results surrounding the prevalence of ignorance in such networks. In the second part of the paper, we compare our own to other related academic practices. We begin by noting that, in digital humanities projects of certain types, the computational component does not appear to directly support the humanities research itself; rather, the digital and the humanities are simply grafted together, not fully intertwined and integrated. PolyGraphs is notably different: the computational work directly supports the investigation of the primary research questions, which themselves belong decidedly within the humanities in general, and philosophy in particular. This suggests an affinity with certain projects in the computational social sciences. But despite these real similarities, there are differences once again: the computational philosophy we practice aims not so much at description and prediction as at answering the normative and interpretive questions that are distinctive of humanities research.

Introduction

Armed conflicts have a severe impact on the health of women and children. Global health emergencies such as pandemics and disease outbreaks further exacerbate the challenges faced by vulnerable populations in accessing maternal, neonatal, and child healthcare (MNCH). There is a lack of evidence that summarizes the challenges faced by conflict-affected pregnant women, mothers, and children in accessing MNCH services during global health emergencies, mainly the Ebola and COVID-19 pandemics. This scoping review aimed to analyze studies evaluating and addressing barriers to accessing comprehensive MNCH services during Ebola and COVID-19 emergencies in populations affected by conflict.

Methods

The search was conducted on PubMed, Scopus, and Web of Science databases using terms related to Ebola and COVID-19, conflicts, and MNCH. Original studies published between 1990 and 2022 were retrieved. Articles addressing the challenges in accessing MNCH-related services during pandemics in conflict-affected settings were included. Thematic analysis was performed to categorize the findings and identify barriers and solutions.

Results

Twenty-nine studies met the inclusion criteria. Challenges were identified in various MNCH domains, including antenatal care, intrapartum care, postnatal care, vaccination, family planning, and the management of childhood illnesses. Ebola-related supply-side challenges mainly concerned accessibility issues, health workforce constraints, and the adoption of stringent protocols. COVID-19 has resulted in barriers related to access to care, challenges pertaining to the health workforce, and new service adoption. On the demand-side, Ebola- and COVID-19-related risks and apprehensions were the leading barriers in accessing MNCH care. Community constraints on utilizing services during Ebola were caused by a lack of trust and awareness. Demand-side challenges of COVID-19 included fear of disease, language barriers, and communication difficulties. Strategies such as partnerships, strengthening of health systems, service innovation, and community-based initiatives have been employed to overcome these barriers.

Conclusion

Global health emergencies amplify the barriers to accessing MNCH services faced by conflict-affected populations. Cultural, linguistic, and supply-side factors are key challenges affecting various MNCH domains. Community-sensitive initiatives enhancing primary health care (PHC), mobile clinics, or outreach programs, and the integration of MNCH into PHC delivery should be implemented. Efforts should prioritize the well-being and empowerment of vulnerable populations. Addressing these barriers is crucial for achieving universal health coverage and the Sustainable Development Goals.

Abstract

Coastal ecosystems are diverse and provide essential global functions, supporting biodiversity conservation, economic growth, and human welfare. However, they are under threat from human activities such as overexploitation, coastal degradation, and anthropogenic impacts. The present study aimed to explore the level of public awareness and understanding of coastal ecosystems in four coastal cities in the Northern Province of Sri Lanka namely Jaffna, Kilinochchi, Mullaitivu, and Mannar. A three-part questionnaire survey was administered to respondents (n = 641) chosen using a systematic sampling method across four coastal cities in the North from April to November 2022. A key highlight from the study is that approximately 75% of the respondents demonstrated significant awareness and knowledge regarding the degradation of the coastal ecosystem in their respective local areas and 81% reported observing an increase in the trend. The influence of social media for awareness was found in nearly half of the respondents followed by mass media (21%). Encouragingly, there is a positive trend among the respondents in recognizing the roles and responsibilities of the government and local community (58%) in addressing coastal ecosystem degradation and promoting conservation efforts. Overall, respondents from Jaffna and Mannar demonstrated a comparatively higher awareness of coastal ecosystems and their degradation than those from Kilinochchi and Mullaitivu. Given their role as transitional zones between terrestrial and marine environments, their intricate socio-ecological dynamics, and the requirement for integrated planning and management strategies, it becomes evident that gaining insight into the level of public awareness of coastal ecosystems is of utmost importance.
