zon. The present encyclopedia is a supplement to its predecessor, The Encyclopedia of the Social Sciences, which was edited by E. R. A. Saligman and Alvin Johnson and published in the early 1930's by Macmillian. The old encyclopedia has won world-wide acclaim for its scholarship and has been of tremendous use to students, scholars, and researchers for the past 35 years. In 1955 a committee was organized to study the possibility of publishing a new encyclopedia. The tremendous growth of the field, together with increasingly newer methods and conceptualization indicated that the time was ripe for starting to work on a new set. The present encyclopedia is impressive in its size and scope. David L. Sills is the editor, Alvin Johnson the honorary editor, and W. Allen Wallis is the chairman of the editorial advisory board, which includes 185 distinguished social scientists. There are sev¬ en associate editors, five special editors, eight members on the editorial staff, and 31 people listed on the production staff. There

In this paper, we study a structured family of matrices whose entries are given by products of $k$-Fibonacci and $k$-Lucas numbers. For this family, we obtain explicit and unified formulas for several classical matrix invariants, including the determinant, inverse, trace, and matrix powers, revealing nontrivial algebraic patterns induced by the underlying recurrence relations. In addition, we determine the spectral radius and the energy of the graphs naturally associated with these matrices. Finally, we establish connections between the resulting formulas and certain integer sequences recorded in the On-Line Encyclopedia of Integer Sequences (OEIS).
This study explores the reception of Russian-language “encyclopedias for girls and boys,” a gender-segregated nonfiction genre that delineates conservative views of femininity and masculinity, serving as a form of sex education and behavioral guidance. This genre can be viewed as part of a broader “cultural backlash” following the fall of communism, analogous to trends in the West that fuel right-wing populism, albeit stemming from different historical contexts. This research investigates the interplay between the normative subjects constructed by these gendered encyclopedias and the agency of readers who may resist these prescribed ideologies. Utilizing qualitative methodology, the study analyzes internet comments from past readers, employing Maria Nikolajeva’s concept of the “identification fallacy” to understand the impact of these texts. Findings suggest that while these books create a shared communicative space for a generation of readers, regardless of gender, the intended imposition of conservative values is often met with irony and skepticism in adulthood, indicating a more nuanced impact on identity formation than the genre’s didactic nature presupposes. Along with reader reception, the social life (bytovanie) of these texts is also reconstructed: from practices of acquisition to transfer and censorship.
