“…2 | THEORETICAL BACKGROUND 2.1 | The concept of generation Generations can be viewed from different perspectives (Rudolph & Zacher, 2017). Generations can be theorized from a sociological perspective looking at generations as social forces facilitating change in societies (Mannheim, 1952), from a cultural perspective claiming that generations shape culture and are not simply shaped by them (Campbell, Campbell, Siedor, & Twenge, 2015), and from a psychological perspective discerning in generations an explanation for behavior (Rudolph & Zacher, 2017). The notions of replacement and temporal succession that are core to generational theory have been applied to various contexts (Alwin & McCammon, 2007;Rudolph & Zacher, 2017), such as "generation as birth cohorts," which is a function of being born at a certain period of time as a formative context; "generation as kinship"; "generation as age-effect" resulting from location in the biological process and in life span development; and "generations as timing of entry into the organization and tenure" pointing to succession in organizations (Joshi, Dencker, & Franz, 2011).…”
