Bliżej praktyki - wzajemne inspiracje nauki i biznesu

Agnieszka Kurczewska, Bożena Mikołajczyk

 Książka jest zbiorem studiów przypadków i refleksji. Powstała w wyniku inspiracji wykładami prowadzonymi dla studentów Wydziału Ekonomiczno-Socjologicznego Uniwersytetu Łódzkiego w ramach cyklu „Bliżej praktyki”. Te z kolei były następstwem bardzo dużego zainteresowania studentów wykładami organizowanymi przez członków funkcjonującej na wydziale Rady Biznesu. Tematy trzech cykli wykładów obejmowały aktualne zagadnienia z zakresu funkcjonowania gospodarki, ekonomii, inwestycji, finansów, zarządzania, a także zagadnienia społeczne. Dużą zaletą spotkań był bezpośredni kontakt z praktykami oraz zetknięcie się z prawdziwymi problemami biznesowymi. Rosnąca popularność wykładów przyczyniła się do rozwinięcia współpracy i spisania najciekawszych doświadczeń. Książka doskonale wpisuje się w potrzeby i zainteresowania wszystkich zaangażowanych stron: uczelni (studentów, kadry akademickiej, władz), jak i pracodawców. Przynosi wymierne korzyści społeczności akademickiej i zacieśnia więzi między środowiskami. Współpraca daje dużą szansę wzmocnienia kontaktów i wymiany pomysłów. Stanowi dopełnienie nawiązanych relacji między uczelnią a praktyką gospodarczą.
