We utilize the social intuitionist approach to moral judgment and moral disengagement theory to understand why and when employees sabotage customers. We contend that when customers mistreat employees (i.e., customer mistreatment), employees experience intuitive emotional reactions in the form of hostility, which automatically activates devaluation of targets, a specific facet of moral disengagement. In turn, employees become unencumbered by moral self-regulation and sabotage customers who mistreat them (i.e...

Timing (phenology) and amount (production) are two integral facets of root growth, and their shifts have profound influences on belowground resource acquisition. The environmental control of, and the effects of nitrogen (N) deposition on, the production and phenology of ectomycorrhizal (ECM) roots, however, remain unclear. Using a four-year minirhizotron experiment, we explored the control of the production and three phenophases (initiation, peak, and cessation of growth) of ECM roots in two soil layers and investigated their dynamic responses to N addition in a seasonally-dry subtropical Pinus elliottii forest...

A phase-resolved reflection-based near-field scanning optical microscopy (NSOM) technique with an original all-fiber configuration is presented. Our system consists of an intrinsically phase-stable common-path interferometer. The reflection from the waveguide input facet or from an integrated fiber Bragg grating is used as the reference beam. This arrangement effectively suppresses the phase drift caused by environmental fluctuations. By raster scanning a silicon atomic force microscope probe, we measure the complex near fields of the propagating and stationary waves in silicon nanowaveguides...

Oxygen-ozone (O3 ) therapy serves as an alternative medical technique that increases the oxygen in the body along with the introduction of O3 . O3 therapy has finally reached a level where the biological mechanisms of action have been understood, showing that they are in the domain of physiology, biochemistry, and pharmacology. Few clinical applications have been reviewed here as well as exemplifying that O3 therapy is particularly useful in musculoskeletal disorders. In the therapeutic range, O3 can be used as a more effective and safe substitute of standard medications...

Many bacterial pathogens rely on quorum sensing to control virulence gene expression. Based on numerous experiments conducted under well-defined conditions, quorum sensing interference is considered as a promising strategy to tackle infections and thus might have the potential to (partially) replace antibiotics. Despite the promising results in well-defined (artificial) laboratory experiments, there still is a lack of knowledge with respect to the impact of quorum sensing interference on the fitness of pathogens in more realistic scenarios, including interactions with a host, the external environment and complex microbial communities...

BACKGROUND: Despite facet joints being three-dimensional structures, previous computed tomography and magnetic resonance imaging studies have evaluated facet joint orientation in only the axial plane. Facet joint orientation in the sagittal plane has rarely been studied using these imaging techniques. The aim of this study was to elucidate facet joint orientation in both the axial and sagittal planes on computed tomography. METHODS: A total of 568 patients (343 men, 225 women) (excluding orthopedic outpatients) for whom abdominal and pelvic computed tomography scans were obtained at our hospital between September 2010 and October 2012 were included...

This study examined the association between post-traumatic growth (PTG), post-traumatic stress disorder (PTSD), and trauma-related factors in cardiac outpatients. Participants recruited from four cardiology clinics between November 2014 and July 2015 (N = 52, 69.2% men, Mage = 65 years) completed self-assessments of PTG and PTSD along with demographic, cardiac health index, and trauma-related factors. In total, 75% of the sample endorsed their cardiac event as traumatic, while 17.2% reported their cardiac event as their 'worst trauma'; those endorsing the latter did not significantly differ from those endorsing 'other traumas' as their worst...

Psoriasis is a chronic systemic inflammatory skin disease, which has been associated with an increased risk of numerous medical and psychiatric comorbidities, including suicidality. Suicidality, which can be divided into the categories of suicidal ideation, suicide attempt, and completed suicide, is highly prevalent in the psoriasis population, and multiple studies have been published on the subject of psoriasis and suicidal ideation and behavior (SIB), including two recent meta-analyses. However, the available literature is limited and inconsistent, and the association between the two remains incompletely understood...

Pregnancy is shaped by unfolding psychological and biological changes in preparation for parenthood. A growing literature has examined the postpartum maternal brain. However, few studies examine the maternal brain during pregnancy, and whether brain function in pregnancy may have implications for postpartum caregiving. Using event-related potentials, we examined the late positive potential (LPP) elicited by infant distress and neutral faces in 35 women during their third trimester of pregnancy. Then, at 3 months postpartum, mothers completed a measure of parental reflective functioning to capture how they regarded their capacity to consider their child's thoughts and feelings...

α-Amino acids (α-AAs) are in extremely high demand in nearly every sector of the food and health-related chemical industries and continue to be the subject of intense multidisciplinary research. The self-disproportionation of enantiomers (SDE) is an emerging and one of the least studied areas of α-AA or enantiomeric properties, critically important for their production and application. In the present work, we report a detailed study of the SDE via achiral, gravity-driven column chromatography for a set of N-acylated, N-carbonylated, N-fluoroacylated, and N-thioacylated α-amino acid esters...

Cardiorenal syndrome represents the confluence of intricate hemodynamic, neurohormonal, and inflammatory pathways that initiate and propagate the maladaptive cross talk between the heart and kidneys. Several of these pathophysiological principles were described in older historical experiments. The last decade has witnessed major efforts in streamlining its definition, clinical phenotypes, and classification to improve diagnostic accuracy and deliver optimal goal-directed medical therapies. The ability to characterize the various facets of cardiorenal syndrome based on its pathophysiology is poised in an exciting vantage point, in the backdrop of several advanced diagnostic strategies, notably cardiorenal biomarkers that may help with accurate delineation of clinical phenotype, prognosis, and delivery of optimal medical therapies in future studies...

Although recognized as the most well-trained providers to address musculoskeletal injuries, many orthopaedic surgeons do not routinely treat patients with nonmusculoskeletal issues in their clinical practice. Nonetheless, when serving as a team physician, an orthopaedic surgeon may need to initiate management of or manage many nonmusculoskeletal issues. Knowing how to accurately diagnose and initiate management of sports-related medical and surgical conditions is an important facet of being an orthopaedic team physician...
