The Firm Size Effect: An Application of Hierarchy Theories
… thesis the positive relationship between firm size and wages is investigated through the application of hierarchy theories. Many different explanations have been proposed for this relationship, but have met only limited success at best. The strongest finding to date is that unobserved ability …

Gap Size Effect on Low Reynolds Number Wind Tunnel Experiments
A system was designed to measure the effect of gap size on semi-span low Reynolds number wind tunnel experiments. The lift forces on NACA 1412, NACA 2412 and NACA 4412 half wings were measured using a strain gauge balance at chord Reynolds numbers of 100,000 and 200,000 and three different gap …

Effect Of Annealing On Copper Thin Films:the Classical Size Effect And Agglomeration
… film or interconnect is known as the "classical size effect". Various theories have been postulated to explain the phenomenon of classical size effect; these theories can be broadly classified as resistivity due to scattering arising from surface and grain boundaries. The total resistivity of …

Grain size effect on structure and properties for chemically-prepared barium titanate
… when prepared as a powder with small particle size $({<}1\mu$m) or as a polycrystalline ceramic with small grain size, displays dramatic deviations in crystal structure and electrical properties, compared with forms involving larger crystallite sizes. Specifically, ceramists have been concerned …

Investigating the size effect of nanoparticles in Click Chemistry mediated cancer targeting
Size is one of the most important properties of nanoparticles (NPs) that affects their biodistribution, accumulation and retention in the tumour tissue. The effect of NP size on tumour targeting has been studied in various contexts, with or without a targeting mechanism incorporated. Herein, we …

Collector size effect on the measurement of applied water depth from irrigation systems
… depth from these sprinklers. The collector size effect on measured water depth and measured depth variability was studied for spinning plate, fixed plate, and wobbling plate sprinkler systems. Five different collector sizes (C2 (5.5 cm), C4 (10.0 cm), C6 (14.8 cm), C8 (20.0 cm), and C10 …

Analyzing the size effect on fracture toughness of mortar through flattened Brazilian tests
… the fracture toughness varies with specimen size. The purpose of this research is to investigate the size effect on the fracture toughness of mortar specimens. First, the methods for calculating elastic modulus, tensile strength, and fracture toughness in previous research are discussed. Some …

Size Effect in Polymeric Materials: the Origins and the Multi-physics Responses in Ultrasound Fields
The size effect in the thermo-mechanical behavior of polymeric materials is a critically important phenomenon and has been the subject of many researches in past decades. For example, polystyrene (PS), a widely used polymeric material, is brittle at the bulk state. When the dimensions decreases to …

Critical size for bulk-to-discrete transition and segment-induced size effect melting of 2D aliphatic layers
Size miniaturization of aliphatic layers is of interest in the fundamental understanding of their structure-property-relationship. This research studies the size-dependence of structure evolution and thermodynamic principles in a model system of silver alkanethiolate (AgSCn), which consists of …

Scanning-group-size effect in flocks of house sparrows : quantifying the contribution of competition and anti-predatory vigilance
As social foraging groups increase in size, individual levels of scanning decrease while time spent feeding increases. Traditionally, anti-predatory considerations provide the preeminent explanation for this scanning-group-size effect, but contest and scramble competition could also account for the …

Scale effects in microindentation of ductile crystals
… the depth of the indentation. This indentation size effect was not observed at the larger length scales. Because indentation testing with conical or pyramidal indenter tips is geometrically similar, the existence of a size effect was surprising. Since the size effect associated with …

Essays on Contest Theory Experiments and Revealed Time Preference Models
… we study the influence of weight and group size in the sequential multi-battle contest with laboratory experiences (Chapter 2 and Chapter 3). We then develop an empirical method to model perceptual present and time inconsistency (Chapter 4). Chapter 2 examines how the weight and the ordered …

Deformation behaviour of additively manufactured microlattice structures : a micro-structural investigation
… materials, which might be subjected to size effect phenomena and in turn would affect the performance of bulk structures. Samples manufactured by laser Powder Bed Fusion (PBF) process using 316L stainless steel were used as the candidate microlattice material, and detailed material …

Two Essays on Asset Pricing
… overall period. The negative relation between size and returns, after controlling for beta differences, is present only when the ex-post market risk premium is negative, and is responsible for the negative relation for the overall period. This paper decomposes the negative relation between size …

A Conventional Theory of Mechanism-Based Strain Gradient Plasticity
CMSG is also used to study the indentation size effect (ISE) observed in micro and nanoindentation experiments. Different hardness trends with different indenter shapes obtained from CMSG agree very well with the experimental measurement.
