Putting PPs into order - Understanding prepositionality in the predominantly postpositional language Lule Sami
This thesis investigates PP-internal word-order variation in an endangered Uralic language, Lule Sami, which is indigenous to parts of Northern Norway and Sweden. The study focuses on the factors underlying prepositional occurrences in this predominantly postpositional language. It is mainly based …

A numerical and experimental investigation of the effects of thermal history on the structure/property relationship of PPS/carbon fiber composites
… mechanical properties of (polyphenylenesulfide) PPS/carbon fiber composites. Three thermal treatments were employed in this study: isothermal crystallization from the melt at 140,160,180,200, and 220°C, quenching from 315° C and then annealing at 160 and 200° C, and nonisothennal crystallization …

Testosterone administration increases the size of womens' peripersonal space: An embodied index of social dominance
Peripersonal space (PPS) is the space immediately surrounding the body, encoded by a specific frontoparietal network of multimodal neurons. Stimuli in PPS are represented in a body-part centred manner in terms of possibilities for action, and PPS representations function to facilitate defensive …

Upholding Gender Equity: Title IX Coordinators' Experiences Supporting Pregnant and Parenting Postsecondary Students
… in supporting pregnant and parenting students (PPS). Purpose: While Title IX mandates protections, accommodations, and institutional support for PPS, implementation varies. Prior research identified macro-level institutional factors influencing PPS support such as enrollment size and U.S. …

The morphology and function of Peyer's patches in the dog
Canine Peyer's patches (PPs) were characterized by immunohistology, alkaline phosphatase histochemistry and electron microscopy. Duodenal PPs were very similar to jejunal PPs, except for the consistent presence of intrafollicular invaginations of the dome epithelium. The single ileal PP had small …

Rational Design of Poly(phenylene sulfide) Aerogels Through Precision Processing
Poly(phenylene sulfide) (PPS), an engineering thermoplastic with excellent mechanical, thermal, and chemical properties, was gelled for the first time using 1,3-diphenylacetone (DPA) as the gelation solvent in a thermally induced phase separation (TIPS) process. PPS was dissolved in DPA at high …

Effect of executive compensation on firm performance
… increase in the pay-performance sensitivities (PPS) provided by CEO stock options and stock holdings. PPS can explain stock returns better as an additional factor to the Fama-French 3-factor model. When CEOs are compensated with higher PPS, firms experience higher return on asset (ROA). The …

SOLVING PROCESS PLANNING AND SCHEDULING PROBLEMS USING THE CONCEPT OF MAXIMUM WEIGHTED INDEPENDENT SET
<p>Process planning and scheduling (PPS) is an essential and practical topic but a very intractable problem in manufacturing systems. Many research studies use iterative methods to solve such problems; however, they cannot achieve satisfactory results in both quality and computational speed. Other …

Crystallization behavior of poly (p-phenylene sulfide): kinetics and morphology
… behaviour of poly (p-phenylene sulfide) (PPS) has been studied. lsothermal rates of bulk crystallization, spherulitic radial growth rates, and nucleation densities were analyzed as functions of molecular weight of PPS, branching agent concentration, and chemical nature of the endgroup …

An investigation of primary stress in spontaneous speech for pedagogical purposes
… W. B. Dickerson's (1995) Primary Phrase Stress (PPS) System, a predictive tool for advanced non-native speakers to use in their practice, was applied to the data to determine areas where the PPS system failed to predict a primary stress, or predicted a primary stress that would be unacceptable to …

The Persistence of Learned Primary Phrase Stress Patterns Among Learners of English
… of the production of nine primary phrase stress (PPS) patterns among international students who successfully completed the pronunciation course ESL 110/410, English Pronunciation for Academic Purposes at University of Illinois at Urbana-Champaign. Data were collected from oral tests administered …

Characterization of the molecular structure at modified polymer surfaces and polyphenylene sulfide/copper interphases
… The optical constants of polyphenylene sulfide (PPS) were determined and exact optical theory was utilized to simulate spectra for a variety of reflectance techniques. This method was also utilized to confirm the ordered state of thin spin coated PPS films. The surface modification of …
