    Description: Sponges (Porifera) are one of the most ancient animals present on the planet. They are aquatic, filter-feeding sessile metazoans that rely on asexual and sexual reproduction. These animals have a long history on Earth and had plenty of time to develop different reproductive strategies. Here, we review different aspects of the physiology of reproduction in Porifera. This chapter is divided into six sections. In the first section, we present general features of sponge reproduction, such as factors that trigger the onset of their reproduction, as well as the periodicity of their reproductive cycles. The molecular basis of the hormonal control of gametogenesis is presented although sponges have no endocrine system. The second section deals with gametogenesis, 2including how sex and the germline are determined and maintained in this group, how oocytes and spermatozoa are formed and nourished, and how they behave once released. The third section reviews different topics about the reproductive mode. Here, we discuss the dichotomy in reproductive mode: oviparity vs. viviparity, the spatial distribution of the reproductive elements in the sponge tissue, the effect of symbiosis in reproduction (and vice-versa), and energetic trade-offs during reproduction. The fourth section describes fertilization, and we cover the factors controlling the spawning events and how the sperm are attracted and recognized by the egg. The diversity of developmental modes, the molecular control of sponge embryonic development, and the maternal-embryo relationship are discussed in the fifth section. Finally, in the sixth section, the types of asexual reproduction, factors influencing budding, gemmulation, hibernation, and gemmule development are described. Knowledge about the physiology of reproduction of sponges is still fragmentary and based on studies in very few species. Consequently, there are many generalizations that need further investigation. However, evidence-based on morphological, experimental, and molecular data demonstrates that their physiology is not very different from that of other metazoans

    Description: The extent of our duties to mitigate climate change is commonly conceptualized in terms of temperature goals like the 1.5°C and the 2°C target and corresponding emissions budgets. While I do acknowledge the political advantages of any framework that is relatively easy to understand, I argue that this particular framework does not capture the true extent of our mitigation duties. Instead I argue for a more differentiated approach that is based on the well-known distinction between subsistence and luxury emissions. At the heart of this approach lies the argument that we have no budget of substantial, net-positive luxury emissions left. In a world in which dangerous climate change has begun, we must expect all further substantial, net-positive luxury emissions to cause harm. Since they lack the kind of justification needed for them to be nevertheless permissible, I conclude that we must stop emitting them with immediate effect. I also briefly discuss the difficult case of subsistence emissions and offer some first thoughts on the morality of a third category of emissions, what I call ‘transition emissions’.

    Description: Misterbianco, located on the southern slope of Mt. Etna (eastern Sicily), was destroyed in the past by two catastrophic events that raised the old town to the ground. The first was the great eruption of 1669, whose lava front buried dozens of villages encountered along its path, entirely destroying the architectural heritage of Etna's southern flank. The second event was the disastrous 1693 Val di Noto earthquake, which caused major destruction throughout south-eastern Sicily, also damaging the few still standing buildings in the town. The GPR survey performed at this site, 350 years after the eruption, allowed a first attempt of planimetric reconstruction of the San Nicolò Church. Starting from the site history, we present the results of an integrated approach that involves history, volcanology and geophysics aimed at addressing future archaeological excavations for the protection of archaeological and monumental assets in a difficult setting as this volcanic environment.

    Description: This collection gathers the contributions of ten scholars on the topic of transnational cultural and physical mobility originating in China. These contributions aim to open conversations among Chinese Studies scholars by applying a Mobility Studies perspective. Exploring diverse narratives and forms of representation from people of Chinese heritage, the book is divided into three parts that each look closely at the relationship between movement and cultural production. The first part is dedicated to four types of mobility of people from China to Italy, namely tourist mobility (Miriam Castorina), labor mobility (Valentina Pedone), student mobility (Xu Hao), and mobility of social elites (Andrea Scibetta). The second part is dedicated to examples of reverse mobility from Italy to China (Gao Changxu, Chiara Lepri, Giuseppe Rizzuto). The third part focuses on case studies based on mobilities from China to territories other than Italy (Rebecca Ehrenwirth, Martina Renata Prosperi, Giulia Rampolla).

    Description: The general aim of this study is to investigate how kids and adolescents conceptualize online privacy and the concern about their online privacy through a developmental perspective, while also trying to understand its impact on a safe online surfing environment. Three studies were conducted: 1) a systematic review, which was aimed to clarify the relative strengths and weaknesses of the literature about the construct of online privacy and online privacy concerns among kids and adolescents; 2) a qualitative study, aimed to understand how adolescents define – and consequently understand – the concept of online privacy; 3) a quantitative study, which aimed at addressing whether online surfing is associated with online privacy concerns and with GDPR (General Data Protection Regulation) differently across different ages during adolescence. Finally, the results of the three studies were analysed and discussed in light of the theory background. An analysis of the literature showed how children may have difficulties to fully understand risks in unusual contexts, and that they can have difficulties in responding to situations when they struggled to recognise or understand fully the risks involved. The results of the three studies are discussed, underlining how adolescents understand their online privacy, if they are concerned about their data online, how we should help them manage better their privacy online, and how we should design services, applications and devices to help kids understand better the implication of the Internet on their ‘onlife’ (Floridi, 2015).

    Description: The article describes the history of higher education in Florence from the beginning of the twentieth century until the mid-1920s, when the ancient Institute of Higher Studies, founded in 1859, was transformed into a modern University. The development of the university institution is reconstructed through the detailed analysis of the annual reports presented by the superintendents of the Institute and making use of the unpublished documents preserved in the historical archives of the University. Particular attention is paid to the evolution of the number of enrolled students and graduates, as well as to the expansion of the training offer made possible by the opening of new faculties and new laboratories. Finally, the article focuses on some important professors, such as the physicist Antonio Garbasso who was also mayor of Florence, and the historian Gaetano Salvemini who was one of the leaders of the anti-fascist movement and, due to his political positions, in 1925 he was forced to leave the University to emigrate to the United States.

    Description: With a focus on migrant narratives, or the storytelling about migration, this volume considers the ways in which migration is and has been shaped by individual and collective experiences of agency, belonging and community. Driven by an agenda of deep listening, each chapter presents a narrative directly derived from qualitative research, an outline of the methodological framing as well as narrative analysis. Through close attention to the narrative, its performative aspects and its ruptures and silences, authors identify patterns and material in the fabric of such telling and retelling of stories that open up new perspectives on the migrant experience. This book develops a methodology of ""dwelling with stories"" that allows for sustained and slow interrogation of the migrant experience and the accompanying decisions that shape narratives around mobility across borders. Its structure is innovative by emphasising the migrant voice and reflecting on the scholars’ positionality, while also offering new theoretical contributions that will advance the field of narrative analysis. The book will appeal to academics, students and practitioners in a wide range of subject areas within the humanities and social sciences, including anthropology, sociology, human geography, migration/refugee/diaspora studies and oral history.

    Description: Based on a research project of the University of Tuscia and of the Alta Scuola SPI-CGIL, the volume delves into Bruno Trentin’s intellectual and political thought, from the CGIL General Secretary to his role in the European Parliament. A network of transnational relationships emerges, stretching from the USA to Europe, from Latin America to South Africa, from the Mediterranean to the Middle East. The ‘Sindacato dei Diritti’ and the European project of the CGIL are thus transferred into the socialist family, in line with Delors’ proposal of a Federation of Nation States, and into the battle of the ‘Spinelli Group’ in favour of the coordination of economic and social policies, of the European Constitution, and of a united Europe in foreign policy and defence. The volume is enriched by unpublished documents in Italian, French, English and Spanish.

    Description: Living with Energy Poverty: Perspectives from the Global North and South expands our collective understanding of energy poverty and deepens our recognition of the phenomenon by engaging with the lived experiences of energy-poor households across different contexts. Understanding the lived experience of energy poverty is an essential component in the design of any effort to alleviate what is fundamentally a deep-rooted, multi-faceted, wickedly complex problem. This requires a nuanced understanding of the causal factors and the research methods that can respond to the flexible spatial and temporal nature of the condition, as well as its wellbeing and justice implications. Drawing together the expertise and connectedness of authors from the Global South and North, this book presents novel approaches to understanding the often hidden forms of domestic energy deprivation. Case studies from 20 countries provide critical perspectives on this phenomenon while analysing the policy practices, government strategy, and sustainability implications of divergent manifestations. The book takes a multidimensional perspective, challenging the bias towards energy production and service provision, which often do not align with the aspirations and realities of energy households across global contexts, thus facilitating a useful dialogue on the nature of energy poverty. The book is a timely source for policymakers, practitioners, and scholars seeking fresh, diverse insights into the everyday reality of energy poverty and wanting to better understand the challenges a people-centred, just energy transition can present.
