Dynamic Organizations: Achieving Marketplace and Organizational Agility with People

Driven by dynamic competitive conditions, an increasing number of firms are experimenting with new, and what they hope will be, more dynamic organizational forms. This development has opened up exciting theoretical and empirical venues for students of leadership, business strategy, organizational theory, and the like. One domain that has yet to catch the wave, however, is strategic human resource management (SHRM). In an effort to catch up, we here draw on the dynamic organization (DO) and human resource strategy (HRS) literatures to delineate both a process for uncovering and the key features of a carefully crafted HRS for DOs. The logic is as follows. DOs compete through marketplace agility. Marketplace agility requires that employees at all levels engage in proactive, adaptive, and generative behaviors, bolstered by a supportive mindset. Under the right conditions, the essential mindset and behaviors, although highly dynamic, are fostered by a HRS centered on a relatively small number of dialectical, yet paradoxically stable, guiding principles and anchored in a supportive organizational infrastructure. This line of reasoning, however, rests on a rather modest empirical base and, thus, is offered less as a definitive statement than as a spur for much needed additional research

Crafting A Human Resource Strategy To Foster Organizational Agility: A Case Study

A decade ago, the CEO of Albert Einstein Healthcare Network (AEHN), anticipating a tumultuous and largely unpredictable period in its industry, undertook to convert this organization from one that was basically stable and complacent to one that was agile, “nimble, and change-hardy”. This case study briefly addresses AEHN’s approaches to business strategy and organization design, but focuses primarily on the human resource strategy that emerged over time to foster the successful attainment of organizational agility. Although exploratory, the study suggests a number of lessons for those who are, or will be, studying or trying to create and sustain this promising new organizational paradigm

Royal Coachman (41CM111) An Early Middle Archaic Site along Cordova Creek in Comal County, Texas

The Royal Coachman site, 41CM111, is bisected by FM 306 near the highway’s eastern crossing of the Guadalupe River. Archeologists from the Texas Department of Transportation conducted extensive excavations at the site in 1980 and the Center for Archaeological Research carried out fieldwork related to geomorphic assessment of the deposits in 2002. The site contains at least three archeological components, an upper zone that may be of late Middle Archaic age and two commingled lower zones that are early Middle Archaic in age and contain a mix of Nolan/ Pandale and Bell-Andice/Early Triangular points. The deeper, more strongly manifested archeological components are associated with a dense burned rock sheet midden composed of two in situ features among a dense scatter of highly disturbed burned rock. Radiocarbon assays place this zone at between 5320–5880 years BP. The lithic assemblage is suggestive of tool manufacture and retooling activities and the projectile point collection is dominated by Early Triangular points and preforms. It is the recommendation of CAR that site 41CM111 warrants designation as a State Archeological Landmark and is eligible for listing on the National Register of Historic Places because of its significant contribution to a better understanding of the regional archeological record. We believe that these investigations have resulted in an appropriate level of work to evaluate the archeological property within the highway ROW and no further work is currently recommended. We also recommend that TxDOT consider avoidance as an option during future construction activities to avert impact to remaining deposits. In addition, if new ROW is acquired, additional work is warranted to determine the extent and significance of currently unidentified material. This work was conducted under Texas Antiquities Committee Permit No. 2807

Resolving IRAS 09111-1007 at 350 microns - a different path to ULIRG formation?

We have resolved the ultraluminous infrared galaxy (ULIRG), IRAS 09111-1007, with the new 350 micron-optimised Second Generation Submillimeter High Angular Resolution Camera (SHARC II) and present the first submillimetre fluxes and images for the system. IRAS 09111-1007 comprises two interacting luminous infrared galaxies (LIRGs) with a projected nuclear separation of 39 kpc. The Western galaxy is roughly four times more luminous in the submillimetre than its Eastern counterpart. It is an extremely bright LIRG with an AGN. The classification of the Eastern source is uncertain: it could be a Seyfert 2 galaxy or a LINER. We highlight IRAS 09111-1007 as a system that necessitates further study: a double AGN ULIRG whose molecular gas content differs from other widely separated pairs and whose ULIRG phase might not be explained by current multiple merger and/or final stage ULIRG scenarios.Comment: 6 pages, 4 figures.

The X-ray Halo of GX 13+1

We present observations of the X-ray halo around the LMXB GX 13+1 from the Chandra X-ray telescope. The halo is caused by scattering in interstellar dust grains, and we use it to diagnose the line-of-sight position, size distribution, and density of the grains. Using the intrinsic energy resolution of Chandra's ACIS CCDs and the recent calibration observation of the Chandra point spread function (PSF), we were able to extract the halo fraction as a function of energy and off-axis angle. We define a new quantity, the ``halo coefficient,'' or the total halo intensity relative to the source at 1 keV, and measure it to be $1.5^{+0.5}_{-0.1}$ for GX 13+1. We find a relationship between this value and the dust size, density, and hydrogen column density along the line of sight to GX 13+1. We also conclude that our data does not agree with ``fluffy'' dust models that earlier X-ray halo observations have supported, and that models including an additional large dust grain population are not supported by these data.Comment: 19 pages, 13 figures, accepted by ApJ.

Fathers stepping up? A cross-national comparison of fathers’ domestic labour and parents’ satisfaction with the division of domestic labour during the COVID-19 pandemic

The COVID-19 pandemic disrupted work and family life around the world. For parents, this upending meant a potential re-negotiation of the ‘status quo’ in the gendered division of labour. A comparative lens provides extended understandings of changes in fathers’ domestic work based in socio-cultural context–in assessing the size and consequences of change in domestic labour in relation to the type of work-care regime. Using novel harmonized data from four countries (the United States, Canada, the United Kingdom, and the Netherlands) and a work-care regime framework, this study examines cross-national changes in fathers’ shares of domestic labour during the early months of the pandemic and whether these changes are associated with parents’ satisfaction with the division of labour. Results indicate that fathers’ shares of housework and childcare increased early in the pandemic in all countries, with fathers’ increased shares of housework being particularly pronounced in the US. Results also show an association between fathers’ increased shares of domestic labour and mothers’ increased satisfaction with the division of domestic labour in the US, Canada, and the UK. Such comparative work promises to be generative for understanding the pandemic’s imprint on gender relations far into the future

First Constraints on Source Counts at 350 Microns

We have imaged a $\sim$6 arcminute$^2$ region in the Bo\"otes Deep Field using the 350 $\mu$m-optimised second generation Submillimeter High Angular Resolution Camera (SHARC II), achieving a peak 1$\sigma$ sensitivity of $\sim$5 mJy. We detect three sources above 3$\sigma$, and determine a spurious source detection rate of 1.09 in our maps. In the absence of $5\sigma$ detections, we rely on deep 24 $\mu$m and 20 cm imaging to deduce which sources are most likely to be genuine, giving two real sources. From this we derive an integral source count of 0.84$^{+1.39}_{-0.61}$ sources arcmin$^{-2}$ at $S>13$ mJy, which is consistent with 350 $\mu$m source count models that have an IR-luminous galaxy population evolving with redshift. We use these constraints to consider the future for ground-based short-submillimetre surveys.Comment: accepted for publication in The Astrophysical Journa

T Cell Activation Markers and African Mitochondrial DNA Haplogroups among Non-Hispanic Black Participants in AIDS Clinical Trials Group Study 384

Introduction: Mitochondrial function influences T cell dynamics and is affected by mitochondrial DNA (mtDNA) variation. We previously reported an association between African mtDNA haplogroup L2 and less robust CD4 cell recovery on antiretroviral therapy (ART) in non-Hispanic black ACTG 384 subjects. We explored whether additional T cell parameters in this cohort differed by mtDNA haplogroup. Methods: ACTG 384 randomized ART-naïve subjects to two different nucleoside regimens with efavirenz, nelfinavir, or both. CD4 and CD8 memory and activation markers were available at baseline and week 48 on most subjects. mtDNA sequencing was performed on whole blood DNA, and haplogroups were determined. We studied non-Hispanic black subjects with HIV RNA <400 copies/mL at week 48. Analyses included Wilcoxon ranksum test and linear regression. Results: Data from 104 subjects were included. Major African mtDNA haplogroups included L1 (N = 25), L2 (N = 31), and L3 (N = 32). Baseline age, HIV RNA, and CD4 cells did not differ between L2 and non-L2 haplogroups. Compared to non-L2 haplogroups, L2 subjects had lower baseline activated CD4 cells (median 12% vs. 17%; p = 0.03) and tended toward lower activated CD8 cells (41% vs. 47%; p = 0.06). At 48 weeks of ART, L2 subjects had smaller decreases in activated CD4 cells (−4% vs. −11%; p = 0.01), and smaller CD4 cell increases (+95 vs. +178; p = 0.002). In models adjusting for baseline age, CD4 cells, HIV RNA, and naïve-to-memory CD4 cell ratio, haplogroup L2 was associated with lower baseline (p = 0.04) and 48-week change in (p = 0.01) activated CD4 cells. Conclusions: Among ART-naïve non-Hispanic blacks, mtDNA haplogroup L2 was associated with baseline and 48-week change in T cell activation, and poorer CD4 cell recovery. These data suggest mtDNA variation may influence CD4 T cell dynamics by modulating T cell activation. Further study is needed to replicate these associations and identify mechanisms

Submillimeter and Far-InfraRed Experiment (SAFIRE): A PI class instrument for SOFIA

SAFIRE is a versatile imaging Fabry-Perot spectrograph covering 145 to 655 microns, with spectral resolving powers ranging over 5-10,000. Selected as a "PI" instrument for the airborne Stratospheric Observatory for Infrared Astronomy (SOFIA), SAFIRE will apply two-dimensional pop-up bolometer arrays to provide background-limited imaging spectrometry. Superconducting transition edge bolometers and SQUID multiplexers are being developed for these detectors. SAFIRE is expected to be a "First Light" instrument, useable during the initial SOFIA operations. Although a PI instrument rather than a "Facility Class" science instrument, it will be highly integrated with the standard SOFIA planning, observation, and data analysis tools.Comment: 11 page
