It is "Twofold" racking my nerve for a while.
Not only should "Twofold" be taken into consideration but a series of them, like- threefold, fourfold, fivefold and so forth.
Should I consider them a replacement of double, triple, four times, five times.
If this is the case, below paragraphs makes no sense to me.
"The importance of this shift in focus is twofold. First, although cognitive models of job satisfaction such as Locke’s (1969) value– percept theory have a certain level of validity, they do not explain a majority of the variance in job satisfaction. Similarly, the dispositional sources of job satisfaction, although important, likewise do not fully explain individual differences in job satisfaction (Ilies & Judge, 2002) and do little to “enlighten the underlying process” (Weiss & Cropanzano, 1996, p. 9). Second, because much of the temporal variation in job satisfaction may therefore be due to variation in mood or affect (Fisher, 2002), studying the affective foundations of job satisfaction may allow us to better predict and understand job satisfaction as it is experienced by individuals. Thus,"
What exactly does twofold mean? as far as I understand it, it is used having two different meanings.
amounts what are increased by multiplying them 2, 3, 4 ,5 ans so forth.
two or more different things having dissimilarity to one another having same concept.
Am I correct?
