Consumer biases in the perception of organizational greed

2022

This article extends current models of how consumers judge or perceive organizations as greedy by employing the theoretical framework of motivated moral reasoning. We show that inherent features of an organization (size and “black sheep” status) and its behavior (relative frequency) bias consumer perceptions of organizational greed. We use an experimental methodology, present subjects with vignettes describing different scenarios, validate our questionnaire using confirmatory factor analysis, and test our hypotheses by employing a general linear model with covariates. Our findings suggest that consumer perceptions of organizational greed are subject to three effects: the underdog effect (St…

Female audit team leaders and audit effort

2022

Abstract Auditing is a collective process conducted by a professional accounting team with a wide range of skills and experience. Audit work is labor-intensive, and audit team diversity, particularly gender diversity, is considered to have both auditing and economic effects. However, there is scant empirical research on the way that audit engagements are conducted and the role of audit team leaders (ATLs), specifically female ATLs, in the audit effort, because they and other audit team members mainly develop audit strategies in practice during the planification period. A hand-collected private data set was gathered from Spanish small and medium-sized audit firms from 2001 to 2015. After con…

Osseointegration of one-piece zirconia implants compared with a titanium implant of identical design: a histomorphometric study in the dog

2010

Objective: The aim of this study was to evaluate osseointegration of one-piece zirconia vs. titanium implants depending on their insertion depth by histomorphometry. Material and methods: Four one-piece implants of identical geometry were inserted on each side of six mongrel dogs: (1) an uncoated zirconia implant, (2) a zirconia implant coated with a calcium-liberating titanium oxide coating, (3) a titanium implant and (4) an experimental implant made of a synthetic material (polyetheretherketone). In a split-mouth manner they were inserted in submerged and non-submerged gingival healing modes. After 4 months, dissected blocks were stained with toluidine blue in order to histologically asse…

Hall effect and electronic structure of films

2010

Abstract Tunneling experiments have shown that in order to retain half-metallicity at room temperature not only a large gap is required but also a Fermi energy considerably distant from the minority band edges. We correlate the position of the Fermi energy in the spin minority gap obtained from band structure calculations to Hall effect experiments. As a model system we chose Co 2 Fe x Mn 1 - x Si , where the Fermi energy was calculated to move from the valence band edge of the minority states to the conduction band edge with increasing x . On high quality laser ablated epitaxial films we observe a sign change of both the normal and the anomalous Hall effect with doping. The experimental da…

Direct observation of Drude behavior in the heavy-fermion by broadband microwave spectroscopy

2005

Abstract Previous optical studies on the heavy-fermion system UPd 2 Al 3 down to frequencies of about 1 cm - 1 ( = 30 GHz ) revealed a well-pronounced pseudogap at low frequencies (below 3 cm - 1 ) that was attributed to magnetic correlations. Thus, the optical conductivity at even lower frequencies is of notable interest because the Drude roll-off (the high-frequency characteristic of a metal which will give information on the quasiparticle dynamics) remained hidden at extremely low frequencies. Using a novel cryogenic broadband microwave spectrometer employing the Corbino geometry we have studied the complex optical conductivity of UPd 2 Al 3 thin films in the frequency range from 45 MHz …

Membrane Stiffness of Animal Cells Challenged by Osmotic Stress

2006

A new approach to assess gold nanoparticle uptake by mammalian cells: combining optical dark-field and transmission electron microscopy.

2012

Toxicological effects of nanoparticles are associated with their internalization into cells. Hence, there is a strong need for techniques revealing the interaction between particles and cells as well as quantifying the uptake at the same time. For that reason, herein optical dark-field microscopy is used in conjunction with transmission electron microscopy to investigate the uptake of gold nanoparticles into epithelial cells with respect to shape, stabilizing agent, and surface charge. The number of internalized particles is strongly dependent on the stabilizing agent, but not on the particle shape. A test of metabolic activity shows no direct correlation with the number of internalized par…

Soft Tissue Healing at One-Piece Zirconia Implants Compared to Titanium and PEEK Implants of Identical Design: A Histomorphometric Study in the Dog

2013

This study aimed to histomorphometrically evaluate the soft tissue reactions of one-piece zirconia implants versus titanium implants in regard to their insertion depth. Four one-piece implants of identical geometry were inserted on each side of six mongrel dogs: an uncoated zirconia implant, a zirconia implant coated with a calcium liberating titanium oxide, a titanium implant, and an experimental implant made of a synthetic material. Using a split-mouth design, they were inserted in both submerged and nonsubmerged healing modes. After 4 months, dissected blocks were stained with toluidine blue to histologically assess the marginal portion of the implant mucosa, apical extension of the barr…

Challenges in automated estimation of capillary refill time in dogs

2018

Capillary refill time (CRT) is a part of the cardiorespiratory examination in dogs. Changes in CRT can reflect pathological conditions like shock or anemia. Visual CRT estimation has low repeatability; therefore, optical systems for automated estimation have recently appeared. Since existing systems are unsuitable for use in dogs, we designed a simple, small and portable device, which could be easily used at veterinary clinic. The device was preliminarily tested on several measurement sites in two dogs. Not all measurement sites were suitable for CRT measurements due to underlying tissue optical and mechanical properties. The CRT measurements were possible on the labial mucosa, above the st…

Patterns of Intention: Royal chapels in the Crown of Aragon (fourteenth-fifteenth centuries) and the Capilla de los Reyes in the Convent of Saint Dom…

2020

El propósito de este estudio es reconsiderar la Capilla de los Reyes en el convento de Santo Domingo, sus posibles funciones y valorar las intenciones de esta fundación de Alfonso V, rey de Aragón, Sicilia y Nápoles. Esta excepcional capilla, célebre por sus bóvedas aristadas de piedra gris, fue construida por el maestro Francesc Baldomar entre 1439 y 1463 y se adscribía a una tradición de lugares de oración asociados a las residencias reales en diversas ciudades de la Corona de Aragón, una entidad compuesta por tres reinos y un principado unidos por el gobierno de una única dinastía. En un período de realeza itinerante era imperativo mostrar magnificencia no sólo en palacios y residencias,…
