Bliżej ludzi. Społeczno-edukacyjne działania Policji na rzecz bezpieczeństwa

Jadwiga Stawnicka, Iwona Klonowska, Rafał Kochańczyk

W niniejszej książce poruszono problematykę, której hasło przewodnie brzmi „Policja bliżej ludzi”. Na tę kwestię autorzy spoglądają z perspektywy trzech filarów uspołecznienia Policji: przywracania posterunków, współpracy dzielnicowych ze społecznościami lokalnymi oraz z perspektywy oceny funk­cjonowania Krajowej Mapy Zagrożeń Bezpieczeństwa przez jej użytkowników.

Bliżej nieba

Kate Breslin

Évelyne Marche, brytyjska pielęgniarka z Oxfordu, mieszka podczas I wojny światowej w okupowanej przez Niemców Brukseli, dzieląc czas pomiędzy pracę w szpitalu w dzień i w kawiarni wieczorem. A przynajmniej takie stwarza pozory… Nikt nie podejrzewa, że wypełnia również ważną szpiegowską misję dla belgijskiego ruchu oporu.  Pewnego dnia Éve dostrzega spadający samolot. Kiedy jako pierwsza dociera na miejsce wypadku, w rannym pilocie rozpoznaje kapitana Królewskiego Korpusu Lotniczego, Simona Forrestera. Ryzykując życie, ukrywa go przed Niemcami, jednak niebezpieczeństwo narasta i mnożą się tajemnice…

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.
