Half a Century of WorkâNonwork Interface Research: A Review and Taxonomy of Terminologies
The extensive interest in the workânonwork interface over the years has allowed scholars from multiple disciplines to contribute to this literature and to shed light on how professional and personal lives are related. In this paper, we have identified 48 terminologies that describe the interface or relationship between work and nonâwork, and have organized them into mature, intermediate, and immature categories according to their stage of development and theoretical grounding. We also provide a taxonomy that places workânonwork interface terminologies into a matrix of six cells based on two dimensions: (1) type of nonwork being narrow or broad; and (2) nature of the mutual impact of work and nonwork domains on one another, characterizing the impact as negative, positive, or balanced. The type of nonwork dimension was informed by Frone's (2003) classification of employeesâ lives into multiple subdomains; the mutual impact dimension was informed by frameworks that organized the literature in part by negative, positive, and balanced workânonwork interface constructs (e.g., Allen, 2012; Greenhaus & Allen, 2011). Theoretical contributions of the proposed taxonomy are discussed along with suggestions on important avenues for future research
Progress in direct-drive inertial confinement fusion research at the laboratory for laser energetics
Direct-drive inertial confinement fusion (ICF) is
expected to demonstrate high gain on the National Ignition Facility (NIF) in
the next decade and is a leading candidate for inertial fusion energy
production. The demonstration of high areal densities in hydrodynamically
scaled cryogenic DT or D implosions with neutron yields that are a
significant fraction of the âcleanâ 1-D predictions will validate the
ignition-equivalent direct-drive target performance on the OMEGA laser at
the Laboratory for Laser Energetics (LLE). This paper highlights some
of the recent experimental and theoretical progress toward this validation.â©The NIF will initially be configured for x-ray drive and with no beams
placed at the target equator to provide a symmetric irradiation of a
direct-drive capsule. LLE is developing the âpolar-direct-driveâ (PDD)
approach that repoints beams toward the target equator. Initial 2-D
simulations have shown ignition. â©LLE is currently constructing the multibeam, 2.6-kJ/beam, petawatt laser
system OMEGA EP. Integrated fast-ignition experiments, combining the OMEGA
EP and OMEGA laser systems, will begin in FY08
Progress in direct-drive inertial confinement fusion
Significant progress has been made in direct-drive inertial confinement fusion research at the Laboratory for Laser Energetics since the 2009 IFSA Conference [R.L. McCrory et al., J. Phys.: Conf. Ser. 244, 012004 (2010)]. Areal densities of 300mg/cm2 have been measured in cryogenic target implosions with neutron yields 15% of 1-D predictions. A model of crossed-beam energy transfer has been developed to explain the observed scattered-light spectrum and laserâtarget coupling. Experiments show that its impact can be mitigated by changing the ratio of the laser beam to target diameter. Progress continues in the development of the polar-drive concept that will allow direct-driveâignition experiments to be conducted on the National Ignition Facility using the indirect-drive-beam layout
