Changeable Manufacturing on the Network Level

AbstractAgility in the sense of changeability on the manufacturing network level, and here especially the business perspective, has received less attention than the other dimensions of changeability on the lower production levels, as well as in relation to the technological perspective. The present paper aims to enrich the concept of agility in the aforementioned sense, taking strategic management concepts into account that have so far received less attention in relation to changeability. Namely, we consider the concepts of lead factory, capacity pooling and allying, operational flexibility, and the concept of combining products, services and software as fruitful enrichments of the umbrella concept changeability. In so doing, we highlight interdependencies between agility and the analyzed concepts as well as the other changeability dimensions on the lower production level of factories or sites. On this basis, we formulate six hypotheses in consideration of the presented theoretical derivations. Hence, the methodological approach of our research is conceptual and hypothesis generating. Our work is supposed to build the basis for continuative conceptual and empirical research on agility

Od žab k ribi

This paper traces the development of "the big-fish-little-pond" effect (BFLPE), which asserts that students in high-ability classes and schools have lower academic self-concepts than their equally able counterparts in low- and mixed-ability environments. The paper begins with a description of the problem outlined in the BFLPE model and continues by examining early BFLPE research and by tracing advances in the field. Criticisms of the BFLPE are outlined and research is described that addresses these criticisms. The paper concludes by presenting suggestions for future BFLPE studies.V prispevku je predstavljen razvoj učinka "velike ribe v majhnem ribniku" (ang. Big- Fish-Little-Pond-Effect), ki ugotavlja, da imajo učenci v oddelkih na najvišjem nivoju nižjo učno samopodobo kot njihovi enako sposobni vrstniki v oddelkih na nižjih nivojih in heterogenih oddelkih. Uvodoma je v prispevku opisan izpostavljeni problem BFLPE modela, nato pa doprinosi na področju njegovega zgodnjega raziskovanja. Na osnovi raziskovalnih spoznanj je predstavljena tudi kritika BFLPE modela ter smernice oziroma predlogi za raziskovanje obravnavanega učinka v prihodnje
