The emotional intelligence of general counsels in relation to lawyer leadership
Few studies have examined lawyer leaders. However, previous research has indicated that effective leaders tend to score high in emotional intelligence. This study investigated the emotional intelligence of general counsels and their beliefs about leadership of millennial lawyers. Emotional intelligence was assessed using the Emotional Quotient Inventory (EQ-i; Bar-On & Handley, 2003). Participants\u27 total mean EQ-i score was nearly identical to that of a normative sample (Bar-On, 2004a) but the current sample scored significantly higher in positive impression, assertiveness, independence, and stress tolerance. In the current sample, males scored significantly higher than females in independence, empathy, adaptability, reality-testing, and flexibility. On average, respondents believed (but not strongly) that millennial lawyers learn differently than lawyers of previous generations and that emotional intelligence and a less managerial approach can enhance leadership of millennial lawyers. Nevertheless, a high percentage reported that their companies had not made specific plans to accommodate the learning differences of millennial lawyers. There was a significant negative correlation between respondents\u27 belief that training in emotional intelligence would help them lead more effectively and both age and number of years practicing law. There was also a significant negative correlation between endorsement of the Socratic method of teaching law students and number of years practicing law (but not the respondent\u27s age). Leadership coaching/training and number of direct reports both showed significant positive correlations with company plans to accommodate the learning differences of the millennial generation
Harmonic and Anharmonic Properties of Diamond Structure Crystals with Application to the Calculation of the Thermal Expansion of Silicon
Silicon has interesting harmonic and anharmonic properties such as the low lying transverse acoustic modes at the X and L points of the Brillouin zone, negative Gruneisen parameters, negative thermal expansion and anomalous acoustic attenuation. In an attempt to understand these properties, a lattice dynamical model employing long range, nonlocal, dipole-dipole interactions was developed. Analytic expression for the Gruneisen parameters of several modes are presented. These expressions explain how the negative Gruneisen parameters arise. This model is applied to the calculation of the thermal expansion of silicon from 5K to 1700K. The thermoelastic contribution to the acoustic attenuation of silicon is computed from 1 to 300 K. Strong attenuation anomalies associated with negative thermal expansion are found in the vicinity of 17K and 125K

The Dog-Child Bond: Examining Synchronous Activity-based Animal-Assisted Interventions for Youth with Developmental Disabilities and their Family Dog
Approximately one in six children in the United States has a developmental disability (CDC, 2018). Among a wide variety of interventions that have been developed to support the health, wellbeing, and development of youth with disabilities, Animal-Assisted Interventions (AAI) have become increasingly prevalent. Some AAI involve youth participating with their own pets, however there has been a lack of research on factors that may impact their participation in such AAI, especially research exploring the dog-child bond. The present study aims to address this gap in the literature by evaluating the pre-existing relationships between children with developmental disabilities (between 8 and 17 years old) and their own family dog. Additionally this work served as an important baseline measure for assessing the efficacy of a novel imitation and synchronous activity-based AAI, and analyzing the impact of the intervention on the quality of the dog-child bond. For this project, the dog-child bond was evaluated in terms of the behavioral synchronization exhibited between the dog and child in a synchronization assessment and the dog’s attachment behavior toward the child in a Secure Base Test. The present study is also the first to evaluate dog-child attachment behavior, with comparison to dog-parent and dog-stranger attachment behavior. The findings indicate that family dogs naturally synchronize their behavior with children at a rate higher than would be expected by chance. Additionally, some children already act as a secure base for their family dog, and for others it is possible, through participation in AAI, to change the attachment style between a dog and child to a more secure attachment. This research demonstrates that although dogs’ bonds to primary adult caregivers are often stronger than to children in the home, there are promising qualities to the dog-child bond that provide an excellent foundation for AAI to build upon, and the present imitation and synchronous activity-based AAI shows excellent potential as an intervention for youth with developmental disabilities
Fiber-optic three axis magnetometer prototype development
The goal of this research program was to develop a high sensitivity, fiber optic, interferometric, three-axis magnetometer for interplanetary spacecraft applications. Dynamics Technology, Inc. (DTI) has successfully integrated a low noise, high bandwidth interferometer with high sensitivity metallic glass transducers. Also, DTI has developed sophisticated signal processing electronics and complete data acquisition, filtering, and display software. The sensor was packaged in a compact, low power and weight unit which facilitates deployment. The magnetic field sensor had subgamma sensitivity and a dynamic range of 10(exp 5) gamma in a 10 Hz bandwidth. Furthermore, the vector instrument exhibited the lowest noise level when only one axis was in operation. A system noise level of 1 gamma rms was observed in a 1 Hz bandwidth. However, with the other two channels operating, the noise level increased by about one order of magnitude. Higher system noise was attributed to cross-channel interference among the dither fields
Thermal noises and noise compensation in high-reflection multilayer coating
Thermal fluctuations of different origin in the substrate and in the coating
of optical mirrors produce phase noise in the reflected wave. This noise
determines the ultimate stabilization capability of high-Q cavities used as a
reference system. In particular this noise is significant in interferometric
laser gravitational wave antennas. It is shown that simple alteration of a
mirror multilayer coating may provide suppression of phase noise produced by
thermorefractive, thermoelastic, photothermal and thermoradiation induced
fluctuations in the coating.Comment: 10 pages, 5 figure

Dog–human behavioral synchronization : family dogs synchronize their behavior with child family members
Research on dog social cognition has received widespread attention. However, the vast majority of this research has focused on dogs’ relationships and responsiveness towards adult humans. While little research has considered dog–child interactions from a cognitive perspective, how dogs perceive and socially engage with children is critical to fully understand their interspecific social cognition. In several recent studies, dogs have been shown to exhibit behavioral synchrony, often associated with increased affiliation and social responsiveness, with their adult owners. In the current study, we asked if family dogs would also exhibit behavioral synchrony with child family members. Our findings demonstrated that dogs engaged in all three measured components of behavioral synchrony with their child partner—activity synchrony (p < 0.0001), proximity (p < 0.0001), and orientation (p = 0.0026)—at levels greater than would be expected by chance. The finding that family dogs synchronize their behavior with that of child family members may shed light on how dogs perceive familiar children. Aspects of pet dog responsiveness to human actions previously reported in studies with adult humans appear to generalize to cohabitant children in at least some cases. However, some differences between our study outcomes and those reported in the dog–adult human literature were also observed. Given the prevalence of families with both children and dogs, and the growing popularity of child-focused animal-assisted interventions, knowledge about how dogs respond to the behavior of human children may also help inform and improve safe and successful dog–child interactions.Keywords: Behavioral synchronization,

Numerical investigations of apatite ^4He/^3He thermochronometry
Apatite ^4He/^3He thermochronometry has the potential to constrain cooling histories for individual samples provided that several presently untested assumptions are valid. Here we simulate the sensitivity of ^4He/^3He spectra to assumptions regarding geometric model, crystallographic anisotropy, broken grain terminations, parent nuclide zonation, and the accuracy of results obtained from analyses of aggregates of multiple crystals. We find that ^4He/^3He spectra obtained from a cylinder with isotropic diffusion are almost indistinguishable from those obtained from an equivalent sphere with an equivalent initial ^4He distribution. Under similar conditions anisotropic diffusion from the cylinder can greatly bias ^4He/^3He spectra, but only if diffusion is >10 times faster in the axial than the radial direction. Existing data argue against anisotropy of this magnitude. We find that analysis of apatites with broken terminations will also bias ^4He/^3He spectra, but not greatly so. In contrast, we find that zonation of a factor of 3 in parent nuclide concentration produces ^4He/^3He spectra that deviate substantially from the homogeneous model. When parent nuclides are highly concentrated near the grain rim and/or cooling is fast, the resulting ^4He/^3He spectra will be readily identified as aberrant. However, more subtle zonation, higher concentrations in the grain interior, or samples that have cooled slowly regardless of zonation style can yield ^4He/^3He spectra that look acceptable but will lead to inaccurate thermochronometric interpretation if parent homogeneity is assumed. Finally, we find that analysis of an aggregate of crystals with identical ^4He distributions can yield ^4He/^3He spectra (and diffusion Arrhenius arrays) that are very different from those that would be obtained on the individual crystals if even small variations in He diffusion exist among the grains. Overall, our observations suggest that modeling tools that assume spherical geometry and isotropic diffusion are appropriate for interpreting apatite ^4He/^3He spectra. However, it is essential to analyze only individual crystals and to assess the degree of parent nuclide zonation in those crystals
