Even the best managers often view employee coaching and feedback as necessary evils. In this work, Allen provides managers with a simple yet powerful approach to revolutionizing feedback conversations and making them a regular and even welcome part of their duties.

The English edition does not differ essentially from the Polish one. Among the more important supplements I should mention § 6.5 containing elementary information on the notation of mathematical logic. To this supplement I was inclined by the experience of many years. For many students (not for all, perhaps) the notation of definitions of certain notions by means of the logical symbols makes it easier to understand these notions (e.g. the notions of uniform continuity or uniform convergence). Besides that, this supplement is included in the book in such a manner that it can be omitted in reading the whole book. Among other changes introduced in the English text, I should mention the addition of a number of exercises and problems; in the second English edition, many of them have been collected in the Supplement. I am glad also to mention the simplification of certain proofs, and finally the removal of mistakes which were found in the primary text

The basic concepts of a method for a general integral of the Field Equations of the Theory of General Relativity are outlined. An extended and revised version is currently in preparation, and it will be uploaded as soon as ready for publication.

This sumptuous book, a feast of nostalgia, celebrates the wonderful era of the European Formula 2 Championship, 1967-84, on the 50th anniversary of its beginnings. Formula 2 pitted emerging heroes against the greats of the day and virtually all the top Formula 1 drivers - names like Jackie Stewart, Jack Brabham, Graham Hill, Jochen Rindt and Bruce McLaren in 1967 - battled with young chargers in races that thrilled huge crowds at the best European circuits, from the Nürburgring to Brands Hatch. In bringing the glory days of Formula 2 back to life in this book, passionate author Chris Witty has interviewed many of the surviving protagonists to present a colourful and evocative retrospective, supported by the work of Jutta Fausel, who photographed Formula 2 races throughout this period. Birth of the European Formula 2 Championship in 1967, when Jacky Ickx (the writer of the book's foreword) became the first champion, driving a Tyrrell-entered Matra. French Matra cars propelled the next two champions, Jean-Pierre Beltoise (1968) and Johnny Servoz-Gavin (1969), both Frenchmen. Of all the manufacturers of Formula 2 cars, March achieved the most success, Ronnie Peterson (1971) becoming the first of six champions to win in these British-built cars. A fine all-British year, 1972, saw ex-motorcycle 'great' Mike Hailwood win the championship in a Surtees car. French champions in five consecutive years: Jean-Pierre Jarier (1973), Patrick Depailler (1974), Jacques Laffite (1975), Jean-Pierre Jabouille (1976) and Rene Arnoux (1977) dominated their era and all but Jarier went on to become Grand Prix winners. Toleman and Ralt cars - also made in Britain - emerged in the final years of the championship, which saw three more British champions: Brian Henton (1980), Geoff Lees (1981) and Jonathan Palmer (1983). The other champions were Clay Regazzoni (1970), Bruno Giacomelli (1978), Marc Surer (1979), Corrado Fabi (1980) and Mike Thackwell (1984).

The offertory has played a crucial role in recent vigorous debates about the origins of Gregorian chant. Its elaborate solo verses are among the most splendid of chant melodies, yet the verses ceased to be performed in the twelfth and thirteenth centuries, making them among the least known and studied members of the repertory. Rebecca Maloy now offers the first comprehensive investigation of the offertory, drawing upon its music, texts, and liturgical history to shed new light on its origins and chronology. Maloy addresses issues that are at the very heart of chant scholarship, such as the relationship between the Gregorian and Old Roman melodies, the nature of oral transmission, the presence of non-Roman pieces in the Gregorian repertory, and the influence of theoretical thought on the transmission of the melodies. Although the Old Roman chant versions were not recorded in writing until the eleventh century, it has long been assumed that they closely reflect the eighth-century state of the melodies. Maloy illustrates, however, that rather than preserving a pristine earlier version of the melodies, the prolonged period of oral transmission from the eighth to the eleventh centuries instead enforced a formulaic trend. Demonstrating that certain musical and textual traits of the offertory are distributed in distinct patterns by liturgical season, she outlines new chronological layers within the repertory, and along the way, explores the presence and implications of foreign imports into the Roman and Gregorian repertories. Carefully weighing questions surrounding the origins of elaborate verse melodies, Maloy deftly establishes that these melodies reached their final form at a relatively late date. Available for the first time as a complete critical edition, ninety-four Gregorian and Old Roman offertories are presented on a companion website in transcriptions which readers can view side-by-side. The book also provides music examples and essays that elucidate these transcriptions with significant insights into their similarities and differences. Inside the Offertory will be an important and longstanding resource for all students and scholars of early liturgical music, as well as performers of early music and medievalists interested in music.
