TL;DR: This paper developed Weick's notion of complicated understanding by linking it with concepts of complementarity, cognitive complexity, and adult development and described a rationale for, and design elements of, management education programs aimed at increasing complicated understanding in administrators, primarily by fostering differentiation and integration of perspectives on organizational problems.
Abstract: This paper develops Weick's (1979) notion of “complicated” understanding by linking it with concepts of complementarity, cognitive complexity, and adult development The paper describes a rationale for, and design elements of, management education programs aimed at increasing complicated understanding in administrators, primarily by fostering differentiation and integration of perspectives on organizational problems It suggests several outcomes of complicated understanding and indicates ways in which these outcomes, as well as programs aimed at producing them, can be assessed

TL;DR: In this paper, the authors demonstrate optical switching of electrically resonant terahertz planar metamaterials fabricated on ErAs/GaAs nanoisland superlattice substrates.
Abstract: We demonstrate optical switching of electrically resonant terahertz planar metamaterials fabricated on ErAs/GaAs nanoisland superlattice substrates. Photoexcited charge carriers in the superlattice shunt the capacitive regions of the constituent elements, thereby modulating the resonant response of the metamaterials. A switching recovery time of 20 ps results from fast carrier recombination in the ErAs/GaAs superlattice substrates.

TL;DR: It is found that a majority of older Americans with career jobs retire gradually, in stages, rather than all at once, and many are already doing so by moving to bridge jobs after leaving their career employment.
Abstract: Purpose: This article investigates how older Americans leave their career jobs and estimates the extent of intermediate labor force activity (bridge jobs) between full-time work on a career job and complete labor-force withdrawal. Design and Methods: Using data from the Health and Retirement Study, we explored the work histories and retirement patterns of a cohort of retirees aged 51 to 61 in 1992 during a 10-year period in both cross-sectional and longitudinal contexts. We examined determinants of retirement patterns in a multinomial logistic regression model. Results: We found that a majority of older Americans with career jobs retire gradually, in stages, rather than all at once. We also found that the utilization of bridge jobs was more common among younger respondents, respondents without defined-benefit pension plans, and respondents at both the lower and upper ends of the wage distribution. Implications: Older Americans are now working longer than pre-1980s trends would have predicted. Given concerns about the traditional sources of retirement income (Social Security, employer pensions, and prior savings), older Americans may have to rely more on earnings. This article suggests that many are already doing so by moving to bridge jobs after leaving their career employment.

TL;DR: It is proposed that the stress, powerlessness, and social isolation at the heart of both phenomena combine to produce posttraumatic stress disorder, depression, and other emotional difficulties.
Abstract: Until recently, the connection between intimate partner violence (IPV) and persistent poverty had been largely ignored. Recent research indicates, however, that the two phenomena cooccur at high rates; produce parallel effects; and, in each other's presence, constrain coping options. Therefore, both external situational, and internal psychological difficulties are missed when women contending with both poverty and IPV are viewed through the lens of just one or just the other. This article describes mental health consequences for women who contend with both partner violence and poverty. It proposes that the stress, powerlessness, and social isolation at the heart of both phenomena combine to produce posttraumatic stress disorder, depression, and other emotional difficulties. The article also introduces the term ''survival-focused coping'' to describe women's methods of coping with IPV in the context of poverty and highlights the role that domestic violence advocates, mental health providers, and researchers can play in addressing these tightly intertwined phenomena.

TL;DR: In this paper, the performance of the Toronto Photo-Oxidation Tube (TPOT) and Potential Aerosol Mass (PAM) flow tube reactors under a variety of experimental conditions was reported.
Abstract: . Motivated by the need to develop instrumental techniques for characterizing organic aerosol aging, we report on the performance of the Toronto Photo-Oxidation Tube (TPOT) and Potential Aerosol Mass (PAM) flow tube reactors under a variety of experimental conditions. The PAM system was designed with lower surface-area-to-volume (SA/V) ratio to minimize wall effects; the TPOT reactor was designed to study heterogeneous aerosol chemistry where wall loss can be independently measured. The following studies were performed: (1) transmission efficiency measurements for CO2, SO2, and bis(2-ethylhexyl) sebacate (BES) particles, (2) H2SO4 yield measurements from the oxidation of SO2, (3) residence time distribution (RTD) measurements for CO2, SO2, and BES particles, (4) aerosol mass spectra, O/C and H/C ratios, and cloud condensation nuclei (CCN) activity measurements of BES particles exposed to OH radicals, and (5) aerosol mass spectra, O/C and H/C ratios, CCN activity, and yield measurements of secondary organic aerosol (SOA) generated from gas-phase OH oxidation of m-xylene and α-pinene. OH exposures ranged from (2.0 ± 1.0) × 1010 to (1.8 ± 0.3) × 1012 molec cm−3 s. Where applicable, data from the flow tube reactors are compared with published results from the Caltech smog chamber. The TPOT yielded narrower RTDs. However, its transmission efficiency for SO2 was lower than that for the PAM. Transmission efficiency for BES and H2SO4 particles was size-dependent and was similar for the two flow tube designs. Oxidized BES particles had similar O/C and H/C ratios and CCN activity at OH exposures greater than 1011 molec cm−3 s, but different CCN activity at lower OH exposures. The O/C ratio, H/C ratio, and yield of m-xylene and α-pinene SOA was strongly affected by reactor design and operating conditions, with wall interactions seemingly having the strongest influence on SOA yield. At comparable OH exposures, flow tube SOA was more oxidized than smog chamber SOA, possibly because of faster gas-phase oxidation relative to particle nucleation. SOA yields were lower in the TPOT than in the PAM, but CCN activity of flow-tube-generated SOA particles was similar. For comparable OH exposures, α-pinene SOA yields were similar in the PAM and Caltech chambers, but m-xylene SOA yields were much lower in the PAM compared to the Caltech chamber.
