Being While Doing: An Inductive Model of Mindfulness at Work
Mindfulness at work has drawn growing interest as empirical evidence increasingly supports its positive workplace impacts. Yet theory also suggests that mindfulness is a cognitive mode of “Being” that may be incompatible with the cognitive mode of “Doing” that undergirds workplace functioning. Therefore, mindfulness at work has been theorized as “being while doing,” but little is known regarding how people experience these two modes in combination, nor the influences or outcomes of this interaction. Drawing on a sample of 39 semi-structured interviews, this study explores how professionals experience being mindful at work. The relationship between Being and Doing modes demonstrated changing compatibility across individuals and experience, with two basic types of experiences and three types of transitions. We labeled experiences when informants were unable to activate Being mode while engaging Doing mode as Entanglement, and those when informants reported simultaneous co-activation of Being and Doing modes as Disentanglement. This combination was a valuable resource for offsetting important limitations of the typical reliance on the Doing cognitive mode. Overall our results have yielded an inductive model of mindfulness at work, with the core experience, outcomes, and antecedent factors unified into one system that may inform future research and practice.

Interplanetary Coronal Mass Ejections observed by MESSENGER and Venus Express
Interplanetary coronal mass ejections (ICMEs) observed by the MESSENGER (MES)
and Venus Express (VEX) spacecraft have been catalogued and analysed. The ICMEs
were identified by a relatively smooth rotation of the magnetic field direction
consistent with a flux rope structure, coinciding with a relatively enhanced
magnetic field strength. A total of 35 ICMEs were found in the surveyed MES
data (primarily from March 2007 to April 2012), and 84 ICMEs in the surveyed
VEX data (from May 2006 to December 2013). The ICME flux rope configurations
have been determined. Ropes with northward leading edges were about four times
more common than ropes with southward leading edges, in agreement with a
previously established solar cycle dependence. Ropes with low inclinations to
the solar equatorial plane were about four times more common than ropes with
high inclinations, possibly an observational effect. Left and right-handed
ropes were observed in almost equal numbers. In addition, data from MES, VEX,
STEREO-A, STEREO-B and ACE were examined for multipoint signatures of the
catalogued ICMEs. For spacecraft separations below 15{\deg} in heliocentric
longitude, the second spacecraft observed the ICME flux rope in 82% of cases;
this percentage dropped to 49% for separations between 15 and 30{\deg}, to 18%
for separations between 30 and 45{\deg}, and to 12% for separations between 45
and 60{\deg}. As spacecraft separation increased, it became increasingly likely
that only the sheath and not the flux rope of the ICME was observed, in
agreement with the notion that ICME flux ropes are smaller in longitudinal
extent than the shocks or discontinuities that they often drive. Furthermore,
this study has identified 23 ICMEs observed by pairs of spacecraft close to
radial alignment. A detailed analysis of these events could lead to a better
understanding of how ICMEs evolve during propagation.Comment: 28 pages, 7 figure
Magnetomechanical damping by polycrystalline TbDy
Vibration damping in polycrystalline TbDy alloys was studied at cryogenic temperatures. Mechanical hysteretic losses were measured at various strains, frequencies, and loading configurations at 77 K. Some textured TbDy materials demonstrated 22.6% energy dissipation in mechanical measurements at low frequency (0.01 Hz) and a mean logarithmic decrement of 0.23 at a higher frequency (25 kHz). Ultrasonic velocities of longitudinal and shear elastic waves were measured on single and polycrystalline TbDy; little variation in ultrasonic velocities was found even for samples with large variation in crystallographic texture and magnetomechanical properties
The Application of the Montage Image Mosaic Engine To The Visualization Of Astronomical Images
The Montage Image Mosaic Engine was designed as a scalable toolkit, written
in C for performance and portability across *nix platforms, that assembles FITS
images into mosaics. The code is freely available and has been widely used in
the astronomy and IT communities for research, product generation and for
developing next-generation cyber-infrastructure. Recently, it has begun to
finding applicability in the field of visualization. This has come about
because the toolkit design allows easy integration into scalable systems that
process data for subsequent visualization in a browser or client. And it
includes a visualization tool suitable for automation and for integration into
Python: mViewer creates, with a single command, complex multi-color images
overlaid with coordinate displays, labels, and observation footprints, and
includes an adaptive image histogram equalization method that preserves the
structure of a stretched image over its dynamic range. The Montage toolkit
contains functionality originally developed to support the creation and
management of mosaics but which also offers value to visualization: a
background rectification algorithm that reveals the faint structure in an
image; and tools for creating cutout and down-sampled versions of large images.
Version 5 of Montage offers support for visualizing data written in HEALPix
sky-tessellation scheme, and functionality for processing and organizing images
to comply with the TOAST sky-tessellation scheme required for consumption by
the World Wide Telescope (WWT). Four online tutorials enable readers to
reproduce and extend all the visualizations presented in this paper.Comment: 16 pages, 9 figures; accepted for publication in the PASP Special
Focus Issue: Techniques and Methods for Astrophysical Data Visualizatio
A Q-methodology study of parental understandings of infant immunisation : implications for health-care advice.
This study used Q-methodology to explore systematically parental judgements about infant immunisation. A total of 45 parents completed a 31-statement Q-sort. Data were collected after vaccination in general practitioner practices or a private day nursery. Q factor analysis revealed four distinct viewpoints: a duty to immunise based on medical benefits, child-orientated protection based on parental belief, concern and distress and surprise at non-compliance. Additionally, there was a common view among parents that they did not regret immunising their children. Implications of these results are discussed in terms of health-care policy and future research
Magnetomechanical effects in textured polycrystalline Tb76Dy24
Uniaxial stress-strain measurements were performed on polycrystalline Tb76Dy24 alloys which exhibit "giant magnetostriction" at cryogenic temperatures. The Young's moduli were reduced by up to a factor of five at 77 K, in comparison to their values at 300 K. We attribute this reduction to a mechanical compliance from domain rotation. Large mechanical hysteresis is also found in nominally elastic stress-strain curves measured below the Curie temperature. Hysteretic curves from 0 to 25 MPa demonstrate up to 19% dissipation of the applied mechanical energy. The anisotropy of thermal expansion was also measured and used as a parameter for the degree of crystallographic texture. This anisotropy was correlated to bulk magnetostriction and to mechanical hysteresis
Aperture synthesis for microwave radiometers in space
A technique is described for obtaining passive microwave measurements from space with high spatial resolution for remote sensing applications. The technique involves measuring the product of the signal from pairs of antennas at many different antenna spacings, thereby mapping the correlation function of antenna voltage. The intensity of radiation at the source can be obtained from the Fourier transform of this correlation function. Theory is presented to show how the technique can be applied to large extended sources such as the Earth when observed from space. Details are presented for a system with uniformly spaced measurements
Worker Morale in Russia: An Exploratory Study
Despite unanimous agreement in the existing literature that morale influences employee performance, no well-defined measure of morale exists. Our study develops a robust measure of morale and focuses on the factors that influence morale among Russian workers. Survey data were collected from Russian employees at two different points in time, 1995 and 2002, in five Russian cities. Among the workers participating in our study, expectation of receiving a desired reward contributes to high morale, with expected monetary rewards having a larger influence than expected non-monetary rewards, but praise for a job well done and a feeling of accomplishment also contribute positively to employee morale. There is a significant correlation between positive attitudes toward work and morale, and a positive correlation between performance assessment and morale. Demographic characteristics (age and gender) have no discernable influence on morale when controls are included for work experience.http://deepblue.lib.umich.edu/bitstream/2027.42/57196/1/wp816 .pd
