Inconsistencies among independent sources of information about psychological constructs are widely documented, but not adequately explained. Measurement error as the primary explanation, though historically popular, is no longer tenable. Yet, even as assessors acknowledge that various measures of the same construct are not necessarily interchangeable, there are no agreed upon frameworks to discern the unique contribution of each measure in multiinformant and multimethod assessment protocols. In this study, we focus on the relevance of the target trait in its measured contexts and on the functional equivalence of the trait across its measures (similar self-regulatory requirements for trait expression) as driving relations between scores...

BACKGROUND: Knowledge of the genotype of melanoma is important to guide patient management. Identification of mutations in BRAF and c-KIT lead directly to targeted treatment, but it is also helpful to know if there are driver oncogene mutations in NRAS, GNAQ or GNA11 as these patients may benefit from alternative strategies such as immunotherapy. METHODS: While polymerase chain reaction (PCR) methods are often used to detect BRAF mutations, next generation sequencing (NGS) is able to determine all of the necessary information on several genes at once, with potential advantages in turnaround time...

Electrocardiogram recordings during opucal mapping experiments in heart tissue are commonly used tu monitor the health of the preparation and to obtain dominant frequencies during arrhythmic and defibrillatory studies. However the use of ECG reconstructed from optical mapping is seldom used and to date it has not been strictly validated. In this manuscript we present the first detailed validation and comparison of Optical Mapping ECG, or OM-ECG, with standard ECG recordings by calculating the electrostatic potential in space as a function of the voltage measured optically and describe the different approximations that can be used to obtain unipolar or bipolar ECG recordings...

BACKGROUND: Enhanced recovery after surgery (ERAS) programs are aimed at minimizing postoperative stress and accelerating postoperative recovery by implementing multiple perioperative principles. "Early mobilization" is one such principle, but the quality of assessment and monitoring is poor, and evidence of improved outcome is lacking. Activity trackers allow precise monitoring and automatic feedback to the patients to enhance their motivation for early mobilization. The aim of the study is to monitor and increase the postoperative mobilization of patients by giving them continuous automatic feedback in the form of a step count using activity-tracking wristbands...

"Triatoma brasiliensis species complex" was defined as a monophyletic group of the species: T. brasiliensis, T. juazeirensis, T. melanica, and T. sherlocki. An alternative grouping scheme proposed the concept of "Brasiliensis subcomplex" which included the former species together with T. melanocephala, T. petrocchiae, T. lenti, T. tibiamaculata, and T. vitticeps. To evaluate the relationship among these taxa we combined the results obtained with four mitochondrial genes (12S, 16S, COI and Cytb, adding to 1,811bp) and geometric morphometric analysis of wings and heads...

Brynn Roach, Tony R Walker
Aquatic monitoring programs are imperative for the functioning of the environmental impact assessment (EIA) process and a cornerstone for industrial compliance in Canada. However, in 2012, several leading pieces of federal environmental legislation (e.g., Canadian Environmental Assessment Act c.19, s. 52, 2012) were drastically altered, effectively weakening levels of environmental protection for aquatic ecosystems during project developments. This paper assesses the impact of CEAA 2012 on aquatic monitoring programs (and subsequent monitoring data reporting) across Canada for ten projects (five completed pre-CEAA 2012 and five completed post-CEAA 2012)...

BACKGROUND: Handling of breast specimen is not well monitored and there is limited data on the impact of fixative solutions on specimen weights. Weight of resected breast tissue acts as a guide for future reconstructive and symmetrisation procedures. The aim is to quantitatively evaluate the discrepancies in weight of fresh breast specimen and the weight of specimen after being kept in a fixative solution for a variable length of time. METHODS: Single centre retrospective cohort study including patients undergone breast surgery for both diagnostic and therapeutic purposes between January of 2013 and June 2015...

Individuals with attention deficit hyperactivity disorder (ADHD) underreport symptoms compared with informants and objective measures. This study applied enhanced statistical methodology (polynomial regression) to the study of ADHD self-reporting to clarify what contributes to symptom underreporting by adolescents with ADHD ( N = 107; ages = 11-15 years). Polynomial regression models were conducted to test competing hypotheses about the nature of self-reporting problems. Traditional difference score models were nested within polynomial regression models to examine how modeling strategy influences results...

The objective of this study was to investigate whether acute pain in abused children was under recognized by doctors and nurses compared to children evaluated for accidental injuries. We hypothesize that an abused child's reaction to physical pain could be an additional symptom of this challenging diagnosis. For the observational prospective case control study in an emergency department, children were eligible when: younger than six years old, the reported trauma occurred within the previous seven days, the trauma comprised a bone injury or burn, and the child was able to express his or her pain...

Accurate information on agricultural water needs and withdrawals at appropriate spatial and temporal scales remains a key limitation to joint water and land management decision-making. We use InVEST ecosystem service mapping to estimate water yield and water consumption as functions of land use in Fresno County, a key farming region in California's Central Valley. Our calculations show that in recent years (2010-2015), total annual water yield for the county has varied dramatically from ~0.97 km(3) to 5.37 km(3) (all ± ~17%; 1 MAF ≈ 1...

Ion mobility-mass spectrometry (IM-MS) can be a powerful tool for determining structural information about ions in the gas phase, from small covalent analytes to large, native-like or denatured proteins and complexes. For large biomolecular ions, which may have a wide variety of possible gas-phase conformations and multiple charge sites, quantitative, physically explicit modeling of collisional cross sections (CCSs) for comparison to IMS data can be challenging and time-consuming. We present a "trajectory method" (TM) based CCS calculator, named "Collidoscope," which utilizes parallel processing and optimized trajectory sampling, and implements both He and N2 as collision gas options...

The ability of ants to navigate when the visual landmark information is altered has often been tested by creating large and artificial discrepancies in their visual environment. Here, we had an opportunity to slightly modify the natural visual environment around the nest of the nocturnal bull ant Myrmecia pyriformis We achieved this by felling three dead trees, two located along the typical route followed by the foragers of that particular nest and one in a direction perpendicular to their foraging direction...

A comprehensive review and analysis of the literature on echinoids from Sri Lankan waters were conducted to compile an annotated list that integrates the existing published data with original data from recent research. According to the published literature, 115 echinoid species and one subspecies have been reported from Sri Lanka to date. However, the current study revealed that only 66 echinoid species and one subspecies belonging to 20 families can be verified to occur in Sri Lankan waters. According to the present analysis, 49 species were excluded from the list due to uncertain records (16) or synonymy (33) with other taxa known from the region...

CONTEXT: Patients with cancer are bothered by its diagnosis, treatment, and associated uncertainty. Lack of concordance (LOC) of patients' reporting of their symptoms and quality of life (QOL) with that of their clinicians has been observed in cancer care. However, information regarding the reporting of patients' bother due to aspects of cancer experience and their clinicians' assessment is lacking. OBJECTIVES: To describe cancer patients' bother due to aspects of their disease experience and explore the concordance (LOC) or a lack thereof between patients' and clinicians' reporting of patients' bother and factors associated with it...
