Ignorance by choice: A meta-analytic review of the underlying motives of willful ignorance and its consequences.

People sometimes avoid information about the impact of their actions as an excuse to be selfish. Such "willful ignorance" reduces altruistic behavior and has detrimental effects in many consumer and organizational contexts. We report the first meta-analysis on willful ignorance, testing the robustness of its impact on altruistic behavior and examining its underlying motives.

Collaborative dishonesty: A meta-analytic review.

Although dishonesty is often a social phenomenon, it is primarily studied in individual settings. However, people frequently collaborate and engage in mutual dishonest acts. We report the first meta-analysis on collaborative dishonesty, analyzing 87,771 decisions (21 behavioral tasks; k = 123; n = 10,923).

Psychological science for a responsible sharing economy.

The sharing economy is fueled by trust, which allows strangers to cooperate. To share responsibly, one needs to be aware of the various consequences sharing has on interacting and third parties. When transparency about such consequences is lacking, mutual trust among interacting parties may encourage people to cooperate and share, in turn, creating unintended negative impacts.

Platelet function in dogs with chronic liver disease.

Objectives: To assess platelet function, buccal mucosal bleeding time and plasma von Willebrand factor concentration in dogs with chronic inflammatory and/or fibrotic liver disease and to compare results with those obtained in healthy dogs.

Materials And Methods: Preliminary study including 18 dogs with chronic inflammatory and/or fibrotic liver disease undergoing liver biopsy and 18 healthy age-matched control dogs. Platelet function was assessed by measuring closure time with the PFA-100® analyser using adenosine diphosphate (ADP) as an agonist.

Bile duct obstruction associated with pancreatitis in 46 dogs.

Background: Pancreatitis is a common cause of extrahepatic bile duct obstruction (EHBDO) in dogs. Information describing the clinical course of dogs with pancreatitis associated bile duct obstruction (PABDO) is limited.

Objectives: To describe the clinical course of PABDO in dogs and determine if presumed markers of disease severity are predictors of survival.

Giardia duodenalis assemblages in cats from Virginia, USA.

Giardia duodenalis is considered a species complex that is divided into 8 genetically distinct but morphologically identical assemblages (A-H). Assemblages C-H are generally host adapted, while A and B infect both people and animals and are considered potentially zoonotic. Furthermore, within assemblage A there are four subtypes (AI, AII, AIII, and AIV) of varying zoonotic potential; human isolates belong to AI and AII, while animal isolates belong to AI, AIII and AIV.

Ethical Free Riding: When Honest People Find Dishonest Partners.

Corruption is often the product of coordinated rule violations. Here, we investigated how such corrupt collaboration emerges and spreads when people can choose their partners versus when they cannot. Participants were assigned a partner and could increase their payoff by coordinated lying.

Dacryocystorhinostomy with a thulium:YAG laser-a case series.

We conducted a retrospective chart review of 27 patients-7 men and 20 women, aged 47 to 94 years (mean: 71.3)-with symptomatic epiphora secondary to dacryostenosis who had undergone thulium: YAG (Tm:YAG) laser dacryocystorhinostomy (DCR). Among them, dacryostenosis had been documented in 35 eyes by dacryocystography.

Spontaneous Course of Biliary Sludge Over 12 Months in Dogs with Ultrasonographically Identified Biliary Sludge.

Background: Biliary sludge is associated with gallbladder (GB) dysmotility and mucus hypersecretion suggesting a link between biliary sludge and the formation of GB mucoceles (GBM). If biliary sludge progresses to GBM, treatment to reduce the production and progression of sludge is warranted.

Hypothesis/objectives: The objective of this study was to determine the course of biliary sludge in dogs.

Does Haptoglobin Phenotype Influence Postnatal Morbidity in Preterm Neonates?

Background: Haptoglobin (Hp) is an acute phase protein with antioxidant, bacteriostatic, and anti-inflammatory activities. Hp proteins associated with the three major phenotypes differ in their proinflammatory and anti-inflammatory action. Inflammation and oxidative stress are both involved in most pathophysiological processes in premature infants.

Justifications shape ethical blind spots.

To some extent, unethical behavior results from people's limited attention to ethical considerations, which results in an ethical blind spot. Here, we focus on the role of ambiguity in shaping people's ethical blind spots, which in turn lead to their ethical failures. We suggest that in ambiguous settings, individuals' attention shifts toward tempting information, which determines the magnitude of their lies.

Histopathologic variation between liver lobes in dogs.

Background: Biopsy of the liver evaluates a small portion of tissue, with inferences made to the entire organ. The method and number of biopsies obtained are tempered by consideration of the risks and benefits. Recommendations often include biopsy of more than one liver lobe, although the consistency of histopathology among lobes in dogs is unknown.

A comparison of liver sampling techniques in dogs.

Background: The liver sampling technique in dogs that consistently provides samples adequate for accurate histopathologic interpretation is not known.

Hypothesis/objectives: To compare histopathologic results of liver samples obtained by punch, cup, and 14 gauge needle to large wedge samples collected at necropsy.

Animals: Seventy dogs undergoing necropsy.

Synchronized switching in a josephson junction crystal.

We consider a superconducting coplanar waveguide resonator where the central conductor is interrupted by a series of uniformly spaced Josephson junctions. The device forms an extended medium that is optically nonlinear on the single photon level with normal modes that inherit the full nonlinearity of the junctions but are nonetheless accessible via the resonator ports. For specific plasma frequencies of the junctions, a set of normal modes clusters in a narrow band and eventually becomes entirely degenerate.

Single-photon transistor in circuit quantum electrodynamics.

We introduce a circuit quantum electrodynamical setup for a "single-photon" transistor. In our approach photons propagate in two open transmission lines that are coupled via two interacting transmon qubits. The interaction is such that no photons are exchanged between the two transmission lines but a single photon in one line can completely block or enable the propagation of photons in the other line.

Photon solid phases in driven arrays of nonlinearly coupled cavities.

We introduce and study the properties of an array of QED cavities coupled by nonlinear elements, in the presence of photon leakage and driven by a coherent source. The nonlinear couplings lead to photon hopping and to nearest-neighbor Kerr terms. By tuning the system parameters, the steady state of the array can exhibit a photon crystal associated with a periodic modulation of the photon blockade.

Photon blockade in the ultrastrong coupling regime.

We explore photon coincidence counting statistics in the ultrastrong coupling regime, where the atom-cavity coupling rate becomes comparable to the cavity resonance frequency. In this regime, usual normal order correlation functions fail to describe the output photon statistics. By expressing the electric-field operator in the cavity-emitter dressed basis, we are able to propose correlation functions that are valid for arbitrary degrees of light-matter interaction.

Diagnostic utility of abdominal ultrasonography in dogs with chronic diarrhea.

Background: Chronic diarrhea is common in dogs and has many causes. Ultrasonographic descriptions of many gastrointestinal diseases have been published, but the diagnostic utility of ultrasonography in dogs with chronic diarrhea has not been investigated.

Hypothesis: Diagnostic utility of abdominal ultrasound will be highest in dogs with GI neoplasia and lowest in those with inflammatory disorders.

Diagnostic utility of abdominal ultrasonography in dogs with chronic vomiting.

Background: Chronic vomiting is a common problem in dogs that has many causes. Ultrasonographic descriptions of many gastrointestinal (GI) diseases have been published. However, diagnostic utility of ultrasonography in dogs with chronic vomiting has not been investigated.

Idiopathic eosinophilic masses of the gastrointestinal tract in dogs.

Background: Eosinophilic inflammation of the gastrointestinal tract of dogs occurs in numerous disorders, typically resulting in diffuse intestinal thickening. Rarely, eosinophilic masses have been reported.

Objective: Describe a series of dogs with 1 or more idiopathic eosinophilic gastrointestinal masses (IEGM) to better characterize the clinical features, treatment, and prognosis.

Effects of prednisone alone or prednisone with ultralow-dose aspirin on the gastroduodenal mucosa of healthy dogs.

Background: The coadministration of prednisone and ultralow-dose aspirin has been recommended for the management of various diseases, but the safety of this combination in dogs has not been studied.

Hypotheses: The gastroduodenal lesions associated with prednisone and ultralow-dose aspirin administration will be similar to those caused by prednisone alone, but both treatments will result in more severe lesions than placebo.

Animals: Eighteen healthy adult purpose-bred dogs.
