Sustainable Tourism and the Grand Challenge of Climate Change
Global climate change represents a grand challenge for society, one that is increasingly influencing tourism sector investment, planning, operations, and demand. The paper provides an overview of the core challenges climate change poses to sustainable tourism, key knowledge gaps, and the state of preparedness in the tourism sector. As we begin what is widely considered a decisive climate decade, low sectoral preparedness should be highly disconcerting for the tourism community. Put bluntly, what we have done for the past 30 years has not prepared the sector for the next 30 years of accelerating climate change impacts and the transformation to a decarbonized global economy. The transition from two decades of awareness raising and ambition setting to a decade of determined collective response has massive knowledge requirements and necessitates broad sectoral commitments to: (1) improved communications and knowledge mobilization, (2) increased research capacity and interdisciplinary collaboration, and (3) strategic policy and planning engagement. We in the tourism and sustainability communities must answer this clarion call to shape the future of tourism in a decarbonized and post +3 °C world, for there can be no sustainable tourism if we fail on climate change.

Asian/American curricular epistemicide : from being excluded to becoming a model minority
\"Chinese labor during the California Gold Rush. Japanese internment. Geopolitical segregation. Racial stereotypes. 'Asian/American Curricular Epistemicide: From Being Excluded to Becoming a Model Minority' delves into how these events and issues are portrayed - or, in some cases, ignored - in today's K-12 social studies curricula. The authors? scholarly and personal backgrounds and experiences have specially situated them to undertake this objective yet critical analysis, as they examine the constructed historical narratives of Chinese and Japanese immigration, multiculturalism, and the overall hegemonic narrative as it has been shaped by the politicization of social studies curricula. This content analysis is intended to initiate a broader conversation about the methods behind a curriculum's formation. How is historical information selected, then molded into a particular narrative for public consumption? Through the authors' insightful exploration, educators and citizens alike may better identify how influential entities and agendas shape curricula behind the scenes. The authors hope that the light they bring to bear on this topic will equip readers to conduct their own analysis and to be more aware and constructively critical of our K-12 educational system.\"--Cover.

Learning Technology
Written specifically for all FE and post-16 teachers, this book will help you to develop your digital capabilities and give you the skills to convert traditional learning and teaching resources into engaging and interactive online material.
The impact of the pandemic means that it is abundantly clear to all that digital capability is vital for learners, no matter what subject they study. You should therefore develop your digital capabilities as a basic competence in order to embrace current digital tools, apps and techniques to the pedagogy of teaching FE. The book provides you with the knowledge and skills required to source information learning technology (ILT) and content to convert traditional learning and teaching resources into engaging and interactive online material.
It is designed around each aspect of the teaching and training cycle - identifying needs, planning and designing, delivering and facilitating, assessing and evaluating - and includes:
when to use ILT / eLearning
barriers to implementing digital learning
the importance of digital capabilities
ways of keeping up to date and continuing professional development.

Synthesis of monophosphines directly from white phosphorus
Monophosphorus compounds are of enormous industrial importance due to the crucial roles they play in applications such as pharmaceuticals, photoinitiators and ligands for catalysis, among many others. White phosphorus (P4) is the key starting material for the preparation of all such chemicals. However, current production depends on indirect and inefficient, multi-step procedures. Here, we report a simple, effective ‘one-pot’ synthesis of a wide range of organic and inorganic monophosphorus species directly from P4. Reduction of P4 using tri-n-butyltin hydride and subsequent treatment with various electrophiles affords compounds that are of key importance for the chemical industry, and it requires only mild conditions and inexpensive, easily handled reagents. Crucially, we also demonstrate facile and efficient recycling and ultimately catalytic use of the tributyltin reagent, thereby avoiding the formation of substantial Sn-containing waste. Accessible, industrially relevant products include the fumigant PH3, the reducing agent hypophosphorous acid and the flame-retardant precursor tetrakis(hydroxymethyl)phosphonium chloride.State-of-the-art industrial methods for transforming P4 into useful phosphorus compounds currently rely on indirect, multi-step strategies. It has now been shown that straightforward one-pot reactions can convert P4 directly into industrially relevant products while requiring only mild conditions and simple, inexpensive reagents—and can also functionalize P4 catalytically.

Ubiquitin ligation to F-box protein targets by SCF–RBR E3–E3 super-assembly
E3 ligases are typically classified by hallmark domains such as RING and RBR, which are thought to specify unique catalytic mechanisms of ubiquitin transfer to recruited substrates

. However, rather than functioning individually, many neddylated cullin–RING E3 ligases (CRLs) and RBR-type E3 ligases in the ARIH family—which together account for nearly half of all ubiquitin ligases in humans—form E3–E3 super-assemblies

. Here, by studying CRLs in the SKP1–CUL1–F-box (SCF) family, we show how neddylated SCF ligases and ARIH1 (an RBR-type E3 ligase) co-evolved to ubiquitylate diverse substrates presented on various F-box proteins. We developed activity-based chemical probes that enabled cryo-electron microscopy visualization of steps in E3–E3 ubiquitylation, initiating with ubiquitin linked to the E2 enzyme UBE2L3, then transferred to the catalytic cysteine of ARIH1, and culminating in ubiquitin linkage to a substrate bound to the SCF E3 ligase. The E3–E3 mechanism places the ubiquitin-linked active site of ARIH1 adjacent to substrates bound to F-box proteins (for example, substrates with folded structures or limited length) that are incompatible with previously described conventional RING E3-only mechanisms. The versatile E3–E3 super-assembly may therefore underlie widespread ubiquitylation.
Cryo-electron microscopy of neddylated SCF-family ligases interacting with the RBR-type E3 ligase ARIH1 reveals the steps through which E3–E3 super-assemblies ubiquitylate a diverse set of substrates presented on F-box proteins.

The Natural Wood Regime in Rivers
The natural wood regime forms the third leg of a tripod of physical processes that supports river science and management, along with the natural flow and sediment regimes. The wood regime consists of wood recruitment, transport, and storage in river corridors. Each of these components can be characterized in terms of magnitude, frequency, rate, timing, duration, and mode. We distinguish the natural wood regime, which occurs where human activities do not significantly alter the wood regime, and a target wood regime, in which management emphasizes wood recruitment, transport, and storage that balance desired geomorphic and ecological characteristics with mitigation of wood-related hazards. Wood regimes vary across space and through time but can be inferred and quantified via direct measurements, reference sites, historical information, and numerical modeling. Classifying wood regimes with respect to wood process domains and quantifying the wood budget are valuable tools for assessing and managing rivers.
