A matter of size: developmental control of organ size in plants
Current Opinion in Plant Biology, 2001The intrinsic size of plant organs is determined by developmental signals, yet the molecular and genetic mechanisms that control organ size are largely unknown. Ongoing functional analysis of Arabidopsis genes is defining important regulators involved in these mechanisms.

Controlling the size of organs and organisms
Current Opinion in Cell Biology, 2005A key difference between yeast and metazoans is the need of the latter to regulate cell proliferation and growth to create organs (and organisms) of reproducible size and shape. Great progress has been made in understanding how growth, cell size and the cell cycle are controlled in metazoans.

Collaboration, motivation, and the size of organizations
Journal of Organizational Computing and Electronic Commerce, 1996We present an analytical model of an organization that offers operational drivers of limits on team size. The model trades off benefits from collaborative problem solving against the disadvantages of diminishing motivation when groups get large. Collaboration is represented as parallel employee activity combined with frequent sharing of partial ...

Crystal Size and Organization in Bone
Connective Tissue Research, 1989Size measurements of dispersed rat bone crystals show that with age a greater proportion exceeds 400 A in length. The surface fractures of more heavily mineralized bones tend to be smooth and stepped, whereas those of less mineralized bones are fibrous. These observations combined with information reported elsewhere on the crystal-collagen relations in

Delay and size in hierarchical organizations
International Journal of Systems Science, 2000As material and information flow through an organization, work is being performed; its very act incurs time and hence delay. It may be intuitive that, the larger an organization is, the longer the delay will be. This turns out to be not entirely true.

Nature, 1971
THE smallest spherical cell capable of an independent existence is believed to be, in theory, 100 nm. Bodies of this size have been found by electron microscopy in cultures of mycoplasmas but they are probably inviable1,3,4. The existence of living mycoplasmas as small as 125 nm is indicated by their ability to pass through filters of known porosity5–8,

Size, complexity, and organization
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2015Bayesian networks and influence diagrams are powerful methods for modeling complex relationships between variables, but the usefulness of these networks is dependent on the way that an analyst arranges the model’s structure. Model misspecification is perhaps most likely to occur when the model starts to become large or the relationships complex.

Notes a broad agreement that small and medium‐sized enterprises (SMEs) fulfil a critical role in modern economies, and therefore their ability to survive, remain competitive and produce high quality outputs is of utmost importance at both micro and macro levels. Focuses on total quality management (TQM), a new management paradigm, which is successfully

Ecological determinism increases with organism size
Ecology, 2012After much debate, there is an emerging consensus that the composition of many ecological communities is determined both by species traits, as proposed by niche theory, as well as by chance events. A critical question for ecology is, therefore, which attributes of species predict the dominance of deterministic or stochastic processes.

Economic Size of Organizations
California Management Review, 1968A popular conception is that large organizations are inherently inefficient. In this article the conclusion is reached that size need not necessarily cause managerial inefficiencies, even in the largest concerns.
