“…A lack of experience and commitment of participants (e.g., Barnes et al, 2002 ; Gaskill et al, 2003 ; Bozeman et al, 2016 ) and unprofessional or inefficient leadership and management (e.g., Adler et al, 2009 ; Bozeman et al, 2016 ; Volk, 2021 ) are further recurrent problems. Less frequently named examples are a lack of sustainability in funding (Goddard et al, 2006 ; Adler et al, 2009 ; Volk, 2021 ), the relation between individual costs and benefits (Berlemann and Haucap, 2015 ), geographical distance (Goddard et al, 2006 ; Cummings and Kiesler, 2008 ; Volk, 2021 ), the size of the research team (e.g., Cummings and Kiesler, 2008 ; Cummings et al, 2013 ), a high level of bureaucracy in institutions (e.g., Muriithi et al, 2018 ), or unforeseeable risks like the premature disclosure of results by participants (e.g., Hoecht, 2004 ; Hackett et al, 2017 ; Garcia et al, 2019 ).…”
