This journal is not a popular journal for public, it is a professional research level journal for scientist and artist, even for litterateur. It focus on many topics in mainstream science, especially for future science. Since this journal is very complicated and professional, so we use the "problem-proposed problem-analysis problem-solving" mode to explain our research, to make readers easier to understand. If you truly want to improve your knowledge by reading this journal, it is better for you to study the problems mentioned in this journal carefully. To write down your unusual solutions for these problems after you have read them. Any good idea about the problems appeared in this journal can be mail to author cheng.

Integrated History and Philosophy of Science (iHPS) is commonly understood as the study of science from a combined historical and philosophical perspective. Yet, since its gradual formation as a research field, the question of how to suitably integrate both perspectives remains open. This volume presents cutting edge research from junior iHPS scholars, and in doing so provides a snapshot of current developments within the field, explores the connection between iHPS and other academic disciplines, and demonstrates some of the topics that are attracting the attention of scholars who will help define the future of iHPS.

While there is growing evidence of the importance of marine ecosystems for our societies, evidence shows also that pressures from human activities on these ecosystems are increasing, putting the health of marine ecosystems at stake worldwide. Hence, Blue Economy is becoming an important component of future socio-economic development strategies (e.g. this is called Blue Growth in Europe), that eventually can result in increasing pressures at sea, and despite the current regulatory framework (in particular with the Oceans Act, in USA or Canada, and the Marine Strategy Framework Directive, in Europe), it is likely that this situation will continue in the future. Ensuring all those connected to the sea, directly or indirectly, gain a better understanding of the importance of the seas, the human-sea interactions and opportunities to act better and reduce impacts from human pressures, is central to Ocean Literacy (OL). Receiving increasing attention in Europe and USA, OL is a challenge for all parts of society: educators & trainers, children and professionals, civil society and scientists, consumers and policy/decision makers. It is seen as part of the package of solutions that will lead to a change in behavior and practice, thus reducing impacts and resulting in healthier marine ecosystems, whilst allowing development opportunities offered by seas are seized in a sustainable manner. This Research Topic focuses on the issues and options for effective OL worldwide. It discusses: (1) existing experiences in OL (formal and informal education for children, training for professionals, tools for raising awareness of consumers - and of investors in the marine sectors...) and their effectiveness (from understanding better to acting differently); (2) the role OL could play (in interaction with innovation, regulation, economic incentive, social norms...) to support human capital development as key component of sustainable growth; and (3) pre-conditions for effective OL for different sectors and target groups. Questions relevant to OL include: Which knowledge - produced by whom - to share and how? Who to target - and how to effectively reach those targeted? How to design OL initiatives - including by mobilizing those targeted (via living lab approaches e.g.) - to ensure effective OL and pave the way for behavior change? What are the knowledge gaps that limit our capacity to design effective OL? As scientists, it is likely you have many more questions to offer and discuss.

Foregrounding street art in the capital cities of Cuba, Haiti, and Puerto Rico, this book argues that Antillean street artists diagnose the “impossible state” of the arrested present (colonized, occupied, or under dictatorship) while simultaneously imagining liberated futures and fully sovereign states. Jana Evans Braziel launches a comparative study of art, politics, history, urban street cultures, engaged citizenships, and social transformations in three Antillean capital cities—Havana, Cuba; Port-au-Prince, Haiti; and San Juan, Puerto Rico—of the Greater Caribbean. The book includes a photo documentary archive of street art, murals, and installations by key muralists in these cities: Yulier Rodriguez Pérez, "Jerry" Rosembert Moïse, and Colectivo Moriviví (Chachi González Colón, Raysa Rodríguez García, and Salomé Cortés). Braziel offers art historical and geopolitical analyses of the urban street art in their cities of production, underscoring street art as political, economic, and environmental engagements (and not as exclusively aesthetic ones) with urban space and street life. The book will be of interest to scholars working in art history, Caribbean studies, Latin American studies, and urban studies.

This report examines digitalisation’s effects on science, technology and innovation and the associated consequences for policy. In varied and far-reaching ways, digital technologies are changing how scientists work, collaborate and publish.

The world's fastest growing continent demographically, Africa displays nearly all the features of today's global security challenges: armed conflict, terrorism, irregular migration, organized crime, great power competition, public discontent, and economic turbulence. John Siko and Jonah Victor present their lessons from professional practice and pedagogical approach from the classroom in a concise guidebook that leads students and professionals through the most important issues, dynamics, challenges, and considerations for analysing and planning responses to security developments in Africa. This book provides issue-by-issue primers on the causes and consequences of Africa's security challenges that include: -how to anticipate security problems across current political and economic events -how to analyse African security institutions and military capabilities -how to understand historical trends across the African continent and appreciate unique variations among countries. -how to identify key drivers of future trends -how to connect security analysis to policy planning Learning is supported through the following features: - Thematic chapters which are optimized to help the reader quickly connect to the key concepts and analytic frameworks within the field. - The most relevant historical case studies, enabling students to engage in sophisticated analysis and discussion. - Connections and contrasts between the situations in North Africa and sub-Saharan Africa, which are traditionally studied separately. - Special sections on understanding race and ethnicity, and advice on traveling in Africa. - Chapter-end checklists of key questions to enable practical engagement with the topics covered.

The last five years have been extremely challenging, but also very innovative for cephalopod science, and the outstanding tradition of biological contribution with cephalopod molluscs as key players in science and human activities and interests has continued. This Research Topic is one of several dedicated to cephalopod molluscs (e.g., Hanke and Osorio, 2018; Ponte et al., 2018) hosted by Frontiers over the last few years, not to mention other papers published separately. Highlighting of cephalopod science is important because it has much to offer not only the life science community, but also more broadly the public perception of science and its understanding and relationship with scientific endeavour and cephalopods as living organisms and part of our everyday life (at least for most of us). This contribution illustrates the key needs that need to be overcome by the cephalopod research community, i.e. rapid and effective mechanisms for exchange of knowledge and resources, sharing of laboratory protocols, videos, tissues, samples and data-sets, innovative approaches and initiatives in public engagement. The cuttlefish comic included is an excellent example of a type of media that can be used to expand scientific knowledge to the public and human relationship with live animals. There are strategic challenges in convincing globally distributed policy makers and funders of the relevance of cephalopods in scientific advances, and also in the regulatory aspects, since cephalopods are the only invertebrates whose use is regulated in Europe in a research context and this increases the need for integrated oversight and direction in terms of ethics and animal welfare (e.g., Jacquet et al., 2019a; 2019b; Ponte et al., 2019). This Research Topic also aligns with the interests of the cephalopod community in stimulating public interest in cephalopods extending to a broader audience that could include chefs and gourmets, and fishers and scientists aiming to develop sustainable food resources. “CephsInAction: Towards Future Challenges for Cephalopod Science” Research Topic includes 14 papers from about 40 authors representing ten different countries, thus overlapping with the original parties that contributed to the COST FA1301 that, together with CephRes, promoted and supported this editorial initiative.
