What Are the Difficulties in Establishing and Interpreting the Results from a Long-Term Manipulationructure and function of the system. One test of the researcher’s knowledge of the system is to draw a conceptual model of the relationships that are important within the system. If such a conceptual model cannot be drawn, then the researcher’s knowledge may be inadequate for testing hypotheses.作者: 稱贊 時(shí)間: 2025-3-22 10:44

Although this chapter will critically evaluate the potential contributions of experimentation to ecological understanding, I must stress at the outset that ecological research requires a synthetic approach in which observational, experimental, and theoretical approaches are pursued in a simultaneous, coordinated, interactive manner.作者: airborne 時(shí)間: 2025-3-22 14:45

Einleitung, schnelle technologische Wandel verst?rkt diesen Innovationsdruck (Drucker, 1969, S. 42ff.). Dies zeigt sich nicht zuletzt an der steigenden Anzahl von Publikationen auf dem Gebiet der Innovationsforschung und dem Bewusstsein für Innovationen in Wissenschaft und Praxis (Fagerberg & Verspagen, 2009).
