Metropolitan MaaS and DRT Schemes: are they paving the way towards a more inclusive and resilient urban environment?
Mobility-as-a-Service and Demand-Responsive-Transport schemes are
promoting progressively a user-centered approach, made of modularity, flexibility
and tailor-made travel experience, and pandemic emergency has furthermore
enhanced this new way of thinking, thus representing an unprecedented occasion to
develop a new paradigm for a more sustainable and resilient transport system, thus
ensuring a greater level of social and territorial inclusion beyond traditional urban
borders and outdated distinctions of targeted services for particular users' categories.
This paper discusses the main features of MaaS and DRT schemes in order to assess
if they could be able to cope with Universal Design principles and to improve
metropolitan accessibility accordingly to the urgent request for social and territorial
inclusion as sustainable development pre-requisites, made by different stakeholders
in the international and European debate (see UNO SDGs or EU Cork Declaration
2.0), and re-launched by many national initiatives (SNAI for Italy, Espana VacĂŹa for
SpainâŠ). To re-think metropolitan mobility as a service that can be shaped
accordingly to user's needs and to redefine transport supply as a complex puzzle
made by different and complementary services could represent a unique opportunity
to overcome one of traditional public transport dramatic problems: low mobility
demand, whether it be due to sparsely populated areas or connected with specific
demands of targeted population categories. Hence this paper recalls some of the
recent DRT experiences already active in Genova Metropolitan Area -the so-called
DRINBUS above all- along with the on-demand mobility strategy for Ligurian
internal areas in order to discuss how this new user-centered approach is acting on
the marginalization of remote territories and fragile user categories. The choice to
develop a MaaS scheme could re-shape metropolitan mobility as a comprehensive
and global mosaic made by multiple pieces, thus making more resilient the entire
system thanks to its modularity and redundancy. This allows to make more
sustainable "niche" services as well, according to the systemic nature of this
mobility platform, thus opposing the present unsuccessful approach of creating adhoc options, focusing indeed on the user's request to travel from point A to point B,
without the need to define him as urban resident, commuter, disabled or not, towards
a greater social inclusion and territorial cohesio
Known Glass Compositions in Iron Age Europe - Current Synthesis and Emerging Questions
Ancient glass has been extensively studied from a technological and raw material provenance perspective since the middle of the 20th century. With the rising applications of analytical techniques in the field of Heritage Studies, the last two decades saw an exponential increase in publications on ancient and historical glass technology from around the globe. Given the amount of works on glass chemical composition, it is surprising to note that the long-held production model for Iron Age glasses found in Europe has only recently been challenged by the publication of uncharacteristic glass compositions. Traditionally, LBA glass industries based on plant-ash fluxes/HMG (Egypt and the Levant) and mixed-alkali fluxes/LMHK (Italy) are thought to be supplanted by natron-fluxed/LMG production operating in Egypt and the Levant since around the 9th century BCE. Recently, however, arguments have been put forth for a more diversified network of glassmaking traditions, including small-scale autonomous European workshops. This article reviews the current state of research into Iron Age (1st millennium BCE) glasses in Europe by examining the available published data on glass compositions to critically assess some practical and theoretical issues stemming from this heterogenous field of research. Key questions are addressed, and future lanes of research are proposed
Building âimplicit partnershipsâ? Financial long-term care entitlements in Europe
The design of public subsidies for long-term care (LTC) programmes to support frail, elderly individuals in Europe is subject to both tight budget constraints and increasing demand preassures for care. However, what helps overcoming the constraints that modify LTC entitlements? We provide a unifying explanation of the conditions that facilitate the modification of public financial entitlements to LTC. We build on the concept of âimplicit partnershipsâ, an implicit (or âsilentâ) agreement, encompassing the financial co-participation of both public funders, and families either by both allocating time and/or financial resources to caregiving. Next, we provide suggestive evidence of policy reforms modifying public entitlements in seven European countries which can be classified as either âimplicit user partnershipsâ or âimplicit caregiver partnershipsâ. Finally, we show that taxpayers attitudes mirror the specific type of implicit partnership each country has adopted. Hence, we conclude that the modification of long-term care entitlements require the formation of some type of âimplicit partnership'
Why the views of middle class citizens help explain increased choice in European healthcare systems
Several countries across Europe have attempted to reform their health systems by allowing patients more choice over their healthcare provider. The typical rationale for this strategy is that by creating competition between providers, there will be an increased incentive to improve the efficiency and quality of healthcare. Joan Costa-i-Font and Valentina Zigante assess the underlying factors that have led to European countries adopting this âchoice agendaâ in their healthcare systems. They find that one of the key drivers for this type of reform has been the role of middle class citizens in demanding greater choice over health providers
'The choice agenda' in European health systems: the role of 'middle class demands'
We examine the role of political economy drivers of the choice agenda in European health systems including middle class electoral support. Building on the reform trajectories and current institutional framework in eight western European countries where there have been significant choice reforms, we explore the preferences for choice and health system satisfaction in those countries. We find provider choice to be supported by middle class demands and health systems satisfaction, but weak evidence of other alternative political motivations for the expansion of provider choice. We conclude that in addition to efficiency improvements, provider choice is largely correlated with the demands for choice among the middle class. The provider choice agenda responds as much to political economy consideration as it does to efficiency arguments

Sustainability and Internal Control Systems in the Food and Pharmaceutical Sectors
Sustainability in the food and the pharmaceutical industry has become a hot topic as the several cases of malpractice reported by worldwide media in recent years shows. This research aims at identifying the reasons for the diffusion of non-ethically sustainable practices in these sectors, by evaluating the effectiveness of the companyâs internal controls. To achieve this aim, a content analysis was performed considering the largest European pharmaceutical and food companies, listed on one or more of the main stock exchanges. Main findings underline many internal controlsâ vulnerabilities to corruption
Holography on the lattice: the string worldsheet perspective
We review the study, on the lattice, of the Green-Schwarz gauge-fixed string
action describing worldsheet fluctuations about the minimal surface
holographically dual to the null cusp Wilson loop, useful to evaluate the cusp
anomaly of N = 4 super Yang-Mills (sYM). We comment on discretization,
numerical explorations and challenges for the non-perturbative study of this
benchmark model of gauge-fixed worldsheet actions.Comment: Invited review to be published on European Physics Journal - Special

How Could People and Communities Contribute to the Energy Transition? Conceptual Maps to Inform, Orient, and Inspire Design Actions and Education
Energy Transition (ET) is crucial for sustainable development, impacting inclusive pros perity and social justice. Knowledge development, innovative solutions, and awareness actions become crucial as energy systems transform. ET necessitates behavioural and cultural changes involving individuals in responsible decision making. The active engagement of all societal actors,
including people and communities is essential. The article is authored by a university research team specializing in Design for Sustainability, Service Design, and Design for Experience, and it addresses two central research questions: (i) how can individuals and communities contribute to ET? and (ii) how can design theories, methods, and expertise contribute to generating knowledge and
solutions for ET? The research employs a multidisciplinary literature review and case study analysis.
It is structured into two main sections. The first section examines ET, drawing upon European Union (EU) official documents and academic literature to outline its values, objectives, actors, initiatives, and challenges, focusing on the role of citizens and communities. The second section explores the designâs
contributions, summarizing relevant philosophies and solutions aligned with ET goals, challenges, and bottlenecks. Conceptual maps were created to address the knowledge gap on ET objectives and guidelines, providing design-oriented reference knowledge and principles. The purpose of the research is to define a conceptual framework made up of maps to guide researchers, designers, and
design educators in understanding the complexity of ET and to inspire their intervention proposals
Discovery of Broad Soft X-ray Absorption Lines from the Quasar Wind in PDS 456
High resolution soft X-ray spectroscopy of the prototype accretion disk wind
quasar, PDS 456, is presented. Here, the XMM-Newton RGS spectra are analyzed
from the large 2013-2014 XMM-Newton campaign, consisting of 5 observations of
approximately 100 ks in length. During the last observation (hereafter OBS. E),
the quasar is at a minimum flux level and broad absorption line profiles are
revealed in the soft X-ray band, with typical velocity widths of km s. During a period of higher flux in the 3rd and 4th
observations (OBS. C and D, respectively), a very broad absorption trough is
also present above 1 keV. From fitting the absorption lines with models of
photoionized absorption spectra, the inferred outflow velocities lie in the
range . The absorption lines likely originate from He and H-like
neon and L-shell iron at these energies. Comparison with earlier archival data
of PDS 456 also reveals similar absorption structure near 1 keV in a 40 ks
observation in 2001, and generally the absorption lines appear most apparent
when the spectrum is more absorbed overall. The presence of the soft X-ray
broad absorption lines is also independently confirmed from an analysis of the
XMM-Newton EPIC spectra below 2 keV. We suggest that the soft X-ray absorption
profiles could be associated with a lower ionization and possibly clumpy phase
of the accretion disk wind, where the latter is known to be present in this
quasar from its well studied iron K absorption profile and where the wind
velocity reaches a typical value of 0.3.Comment: 44 pages, including 13 figures, accepted for publication in The
