Book Description
This thesis explores preschool class children’s meaning making processes when they encounter evolution. By adopting social semiotic and sociocultural perspectives on meaning making, three group-based tasks were designed. Video data from the activities were analysed using a multimodal approach. The analysis focuses on how the communicated science content affects the science focus of the tasks, how different materials function as semiotic resources and influence meaning making, and interactive aspects of doing science in the meaning-making processes. The findings reveal that, by using the provided materials and their previous experiences, the children argue for different reasons for animal diversity and evolution. Throughout the tasks, a child-centric view of life emerged in a salient manner. This means that, apart from the science focus, the children also emphasise other aspects that they find important. The child-centric perspective is suggested to be a strength that enables children to engage in science activities. The results show that the provided materials had three functions. Children use materials as resources providing meaning. This means that the children draw on the meaning potential of the materials, a process that is influenced by their previous experiences. Moreover, in interaction with peers, the materials also serve as communicative and argumentative tools. Thus, access to materials influences the children’s meaning making and enables them to discuss evolution and “do science”. The findings also reveal an intimate relationship between task context and interaction. More scripted tasks convey more child–adult interaction (scaffolding) while less scripted tasks, during which children build on previous experiences instead of communicated science content, stimulates child–child interaction (mutual collaboration). In scaffolding interactions, a greater emphasis is placed on the science topic of the task due to guidance from the adult. Consequently, meanings made by children in more scripted tasks are more likely to be “scientifically correct”. However, if the teacher or the adult steps back and allows the children to engage in mutual collaboration, they engage in multiple ways of doing science through evaluating, observing, describing and comparing. Overall, the research reported in this thesis suggests that task contexts and materials have a great impact on children’s meaning making and how science is done. Den här avhandlingen utforskar förskolebarns meningsskapandeprocesser kring evolution. Tre gruppbaserade aktiviteter har designats. Videodata har analyserats utifrån ett multimodalt perspektiv på kommunikation. Analysen fokuserar på hur kommunicerade naturvetenskapliga beskrivningar av evolution påverkar aktiviteternas naturvetenskapliga fokus, materials funktion som semiotiska resurser och påverkan på meningsskapande och interaktiva aspekter av att göra naturvetenskap. Avhandlingens resultat visar att barnen, genom att använda material och sina tidigare erfarenheter, för olika resonemang kring varför djur utvecklas och blir olika. Genomgående har barnens syn på världen en betydande roll för meningsskapandeprocessen. Det betyder att barnen, förutom att fokusera på det naturvetenskapliga innehållet i aktiviteterna, också lägger stor vikt vid andra aspekter som är viktiga för dem. Det barncentrerade perspektivet förslås vara en styrka som möjliggör för barn att delta i och engageras av naturvetenskapliga aktiviteter. De material som barnen har tillgång till de i de olika aktiviteterna har tre funktioner. Barnen använder material som meningsgivande resurser, vilket betyder att barnen använder materialens meningspotential. Denna process påverkas av barnens tidigare erfarenheter. Vidare används materialen som kommunikativa- och argumentativa redskap i interaktion med andra. Tillgången till material påverkar således barnens meningsskapande och möjliggör att de kan diskutera evolution påverkar barnens naturvetenskapliga handlande. Avhandlingens resultat visar på en nära relation mellan uppgifters kontext och interaktion. Mer styrda aktiviteter medför mer interaktion mellan barn och vuxna (scaffolding). Mindre styrda aktiviteter, där barnen bygger på sina tidigare erfarenheter, stimulerar istället interaktion mellan barnen (mutual collaboration). Som ett resultat av den vuxnes agerande, läggs det större vikt vid det naturvetenskapliga innehållet (evolution) i scaffolding-interaktioner. Följaktligen är de meningar som skapas i mer styrda aktiviteter mer i linje med naturvetenskapliga förklaringar till evolution. Samtidigt finns det ett samband mellan att den vuxne kliver åt sidan och att barnen kliver fram och gör naturvetenskapliga handlingar som att utvärdera, observera, beskriva och jämföra. Sammanfattningsvis visar den här avhandlingen att uppgifters kontext och material har stor påverkan på barns meningsskapande och hur de gör naturvetenskap.

Book Description
Freedom in the World, the Freedom House flagship survey whose findings have been published annually since 1972, is the standard-setting comparative assessment of global political rights and civil liberties. The survey ratings and narrative reports on 195 countries and fourteen territories are used by policymakers, the media, international corporations, civic activists, and human rights defenders to monitor trends in democracy and track improvements and setbacks in freedom worldwide. The Freedom in the World political rights and civil liberties ratings are determined through a multi-layered process of research and evaluation by a team of regional analysts and eminent scholars. The analysts used a broad range of sources of information, including foreign and domestic news reports, academic studies, nongovernmental organizations, think tanks, individual professional contacts, and visits to the region, in conducting their research. The methodology of the survey is derived in large measure from the Universal Declaration of Human Rights, and these standards are applied to all countries and territories, irrespective of geographical location, ethnic or religious composition, or level of economic development.

Book Description
Kids learn how to adopt a growth mindset through the familiar structure of the ABCs. Mistakes aren’t just mistakes. They’re growth spurts. Developing a growth mindset—a belief that learning is a process that requires dedication and hard work, not just talent—helps kids learn from their mistakes, build resilience, and strive to be a little better every day. Not your typical alphabet book, Y Is for Yet uses the ABCs as an accessible framework to introduce growth mindset and all its possibilities. From A to Z, or Ability to Zany, kids learn new vocabulary that expands their view of themselves learners. Readers can open to any page and find useful information. Younger children learn new vocabulary, while older kids can increase their knowledge of the brain’s neuroplasticity and the many ways growth mindset can be put into action. A section at the back of the book provides a kid-friendly glossary of terms and activities adults can use to help kids build resilience and foster a growth mindset. With an uplifting and positive tone, Y Is for Yet empowers kids to persevere and encourages them to view learning as a journey with limitless possibilities.

Book Description
The breaking of the Maya code has completely changed our knowledge of this ancient civilization, and has revealed the Maya people's long and vivid history. Decipherment of Maya hieroglyphic writing has progressed to the point where most Maya written texts—whether inscribed on monuments, written in the codices, or painted or incised on ceramics—can now be read with confidence. In this practical guide, first published in 2001, Michael D. Coe, the noted Mayanist, and Mark Van Stone, an accomplished calligrapher, have made the difficult, often mysterious script accessible to the nonspecialist. They decipher real Maya texts, and the transcriptions include a picture of the glyph, the pronunciation, the Maya words in Roman type, and the translation into English. For the second edition, the authors have taken the latest research and breakthroughs into account, adding glyphs, updating captions, and reinterpreting or expanding upon earlier decipherments. After an introductory discussion of Maya culture and history and the nature of the Maya script, the authors introduce the glyphs in a series of chapters that elaborate on topics such as the intricate calendar, warfare, royal lives and rituals, politics, dynastic names, ceramics, relationships, and the supernatural world. The book includes illustrations of historic texts, a syllabary, a lexicon, and translation exercises.

Book Description
The editors and contributors to Color of Violence ask: What would it take to end violence against women of color? Presenting the fierce and vital writing of organizers, lawyers, scholars, poets, and policy makers, Color of Violence radically repositions the antiviolence movement by putting women of color at its center. The contributors shift the focus from domestic violence and sexual assault and map innovative strategies of movement building and resistance used by women of color around the world. The volume's thirty pieces—which include poems, short essays, position papers, letters, and personal reflections—cover violence against women of color in its myriad forms, manifestations, and settings, while identifying the links between gender, militarism, reproductive and economic violence, prisons and policing, colonialism, and war. At a time of heightened state surveillance and repression of people of color, Color of Violence is an essential intervention. Contributors.

Book Description
The COVID-19 pandemic has demonstrated our fragility as a species. Humanity was attacked by a previously unknown virus that spread very rapidly, thanks to a speed of population mobility never before seen in human history. It succeeded in creating the complete upset of the global socio-economic system. Such an event gives us an important stimulus to re-evaluate health in the context of a circular system that encompasses humans and the environment in which we live. The key challenge we face is the discovery of novel paths to crisis resolution. Can we abandon the often cherished, but now rather obsolete, tendency to specialize in a restricted subject area? Can we re-discover the ability to become permeable to ideas that reach us from other disciplines and embrace a thinking-out-of-the-box approach? This book encourages the reader to consider this challenge via the telling of stories, both great and small. Stories that, although sometimes overlooked, have defined the course of our history and thus open the door to a new pathway of progress. In some ways, COVID-19 may have shown the direction nature expects us to take. Ilaria Capua suggests to us that, today more than ever, we are the responsible actors in the circle of life, guardians of our planet and defenders of its health. As one entity of circular nature.
