Sommario/riassunto |
|
Alena Ledeneva invites you on a voyage of discovery to explore society’s open secrets, unwritten rules and know-how practices. Broadly defined as ‘ways of getting things done’, these invisible yet powerful informal practices tend to escape articulation in official discourse. They include emotion-driven exchanges of gifts or favours and tributes for services, interest-driven know-how (from informal welfare to informal employment and entrepreneurship), identity-driven practices of solidarity, and power-driven forms of co-optation and control. The paradox, or not, of the invisibility of these informal practices is their ubiquity. Expertly practised by insiders but often hidden from outsiders, informal practices are, as this book shows, deeply rooted all over the world, yet underestimated in policy. Entries from the five continents presented in this volume are samples of the truly global and |

ever-growing collection, made possible by a remarkable collaboration of over 200 scholars across disciplines and area studies. By mapping the grey zones, blurred boundaries, types of ambivalence and contexts of complexity, this book creates the first Global Map of Informality. The accompanying database (www.in-formality.com) is searchable by region, keyword or type of practice, so do explore what works, how, where and why! |

Sommario/riassunto |

This sequel to the highly successful and much appreciated ""Modern Aldol Reactions"" continues to provide a systematic overview of methodologies for installing a required configuration during an aldol addition step, but shifts the focus so as to cover the latest developments.As such, it presents a set of brand new tools, including vinylogous Mukaiyama-aldol reactions, substrate-controlled aldol reactions and asymmetric induction in aldol additions. Furthermore, novel developments in existing stereoselective aldol additions are described, such as the deployment of supersilyl groups or organ |
