Factors affecting human reliability in the chemical process industry
… are referred to as Performance Shaping Factors (PSFs). Following a period of familiarization within the industry, a number of case studies were undertaken covering a range of basic influencing factors. Plant records and site `lost time incident reports' were also used as supporting evidence for …

Creating multi-stakeholder value by leveraging high performance work practices: an intellectual capital perspective
… of the contemporary Professional Service Firms (PSFs). The ever-increasing acceptance of High-Performance-Work-Practices (HPWPs) and their robust influence on organization’s Intellectual Capital (IC) makes it pertinent for the scholars to further evaluate and enrich this relationship particularly …

Take Charge for Therapy Discharge: Outcomes of a Patient Education Program Applying the CO-OP Approach
… Using the Patient-Specific Functional Scale (PSFS), participants identified and prioritized three therapy goals and rated their perceived current performance. Results demonstrated a significant difference between the participants’ PSFS pre and post-intervention scores. Patients’ improved …

Long exposure point spread function estimation from solar adaptive optics loop data
… led to large uncertainties in the estimated PSFs. The PSF estimation method was tested on real solar observations, where an estimation of the AG-corrected PSF is normally difficult. The observations were deconvolved with the estimated PSFs, producing significantly improved quantitative …

Facial image restoration and retrieval through orthogonality
… combination of a set of pre-defined orthogonal PSFs and similarly, an estimated intrinsic sharp face image (EI) is represented by the linear combination of a set of pre-defined orthogonal face images. In doing so, PSF and EI estimation is simplified to discovering two sets of linear combination …

Adaptive optics aberrometer and wavefront corrector using a twisted-nematic liquid-crystal on silicon chip
… and simulated point spread functions (PSFs), and residual wavefront RMS values in both the pupil and retinal planes were correlated. The closed-loop wavefront corrections with volunteers’ eyes have shown narrowed point spread functions (PSFs) and higher Strehl ratios (SRs). The system …

Advances in volumetric super-resolution microscopy and single-particle tracking
… and double-helix point spread functions (PSFs)---have been developed. These techniques encode the lateral and axial positions of single fluorophores into the PSF shape but at the cost of reduced spatial and temporal resolution. This limitation restricts the compatibility of 3D-SMLM with …

A framework for estimating difficulty and exclusion from tasks of everyday living
… Identifying Performance Shaping Factors (PSFs) and assessing their impact on performance is central to estimating difficulty and potential exclusion from everyday tasks. The analysis of human characteristics in this context is challenging because much of the existing capability data is …

Financialisation of the professional services firm : strategy, governance and the lived experience of partners
… in the regulation and competitive environment of PSFs, and internally in terms of the commercialisation of the PSF and the adoption of financial logics. In an ethnographic case study undertaken within a cultural economy perspective this thesis reveals firstly how PSF strategy has been …

Governing the human capitalists : ownership and authority in the advertising and airline industries
… theoretical views of professional service firms (PSFs) as unstable, small, private partnerships with the empirical reality of large public corporations in several professional service industries. Essay 1 uses a panel of advertising agencies and creativity awards from 1960-1980 to assess whether …

Synthesis and Characterization of Poly(2-Ethyl-2-Oxazoline) Functional Prepolymers and Block Copolymers
… functional telechelic PSF macroinitiators. PSFs are well-known engineering thermoplastics with excellent resistance to hydrolysis and oxidation, as well as displaying good mechanical properties, thermal stability and toughness. Phenol functional PSFs were prepared via step-growth …

Plant-Soil Feedbacks In Heavy Metal Soils
… and environmental health. Plant-soil feedbacks (PSFs), in which plants affect other plants indirectly by modifying the soil they grow in, have been shown to affect many processes critical to successful restoration, but we know little about their generality across ecosystems or how metal …

Point Spread Function Reconstruction for the Adaptive Optics System ALFA and its Application to Photometry
… as well as images. Finally, on- and off-axis PSFs extracted from images were compared to their estimated counterparts, with good agreement found in all cases. Additionally, it could be shown that the photometric accuracy is strongly improved by using a locally estimated PSF as compared to the …

Efficacy of pain scales in athletic populations and paired with aglometric measurements
… as well as patient specific functional scale(PSFS), brief resiliency scale(BRS), and pain catastrophizing scale (PCS) were completed by each subject. Then each participant had their pressure discomfort threshold (PDT) and pressure pain tolerance (PPT) tested with an algometer at 3 …

Gravitational Lensing and Telescope Aberrations
… models for lensed galaxies and for aberrated PSFs, and convolve the two models to determine the analytic form for the gravitationally lensed and optically distorted galaxy shapes that one might expect to see in actual telescope images. Given this representation of the galaxy image, one can …

Techniques in deep imaging within biological tissue
… Taking axial and lateral point spread functions (PSFs), the improvement of the system was monitored. The ability of the adaptive optic system to optimise to a particular axial PSF (PSF engineering) was also examined. The use of various algorithms with an adaptive element in a confocal system has …
