From Warriors to Wingtips: The Leadership Transition of Retired Officers into the Public Sector

For personal and financial reasons some retired military officers seek second careers in the public sector. In entering local government, they are leaving a unique organization, and encountering a very different organizational culture. This study used grounded theory methodology to identify the key military leadership strategies and behaviors learned by military officers and to examine their applicability to local government. It focused on eleven retired naval and marine officers who served twenty or more years, attained a rank of lieutenant commander or major and above, and had worked in local San Diego government at the mid-management or executive level less than six years. Findings were triangulated with literature and other research. Participant data described rapid leadership development as a military priority shaped by early responsibility, education, mentoring and command experiences. Leadership practices include using a contingency leadership style, firm discipline, a controlled environment, straightforward communications, training and development, values, camaraderie building, a command presence, standard operating procedures and centrally-mandated change. Retired officers needed to adjust some military leadership practices to respond to the organizational systems and culture of local government. In addition, each encountered stereotypes of retired military officers that affected their image and capacity to influence their organization. The retired officers interviewed identified strategies that aided them in succeeding in the public sector. These included: using a coaching style to lead staff, following up on directives, actively managing performance, adopting a less direct communications style, improving employee selection and development, creating ownership, actively working to change systems, building influence and political relationships, introducing change by influence, consciously developing their reputation and countering stereotypes of military officers. Some retired officers used strategies that were less successful. These included: using a direct communication style, using military jargon, assuming compliance, accepting and criticizing the status quo, developing an inner circle, expecting the executive to initiate career development and direct change, becoming frustrated, and failing to react to stereotypes

Application of inertial instruments for DSN antenna pointing and tracking

The feasibility of using inertial instruments to determine the pointing attitude of the NASA Deep Space Network antennas is examined. The objective is to obtain 1 mdeg pointing knowledge in both blind pointing and tracking modes to facilitate operation of the Deep Space Network 70 m antennas at 32 GHz. A measurement system employing accelerometers, an inclinometer, and optical gyroscopes is proposed. The initial pointing attitude is established by determining the direction of the local gravity vector using the accelerometers and the inclinometer, and the Earth's spin axis using the gyroscopes. Pointing during long-term tracking is maintained by integrating the gyroscope rates and augmenting these measurements with knowledge of the local gravity vector. A minimum-variance estimator is used to combine measurements to obtain the antenna pointing attitude. A key feature of the algorithm is its ability to recalibrate accelerometer parameters during operation. A survey of available inertial instrument technologies is also given

Laser pulse analysis

Methods are presented for locating threshold points by using laser pulse analysis. It was found that there are errors involved in the determination of each of these quantities, and an attempt was made to separate their effects on the overall range correction. Several series of corrected range measurements for fixed reflectors and satellites were obtained. Residuals were computed by fitting the range measurements to either fixed-reflector distances or short arcs of satellite orbits. Root mean square values of these residuals are presented

Corrections for Racial Disparities in Law Enforcement

Much empirical analysis has documented racial disparities at the beginning and end stages of criminal cases. However, our understanding about the perpetuation of—and even corrections for—differential outcomes in the process remains less than complete. This Article provides a comprehensive examination of criminal dispositions using all DWI cases in North Carolina from 2001 to 2011, focusing on several major decision points in the process. Starting with pretrial hearings and culminating in sentencing results, we track differences in outcomes by race and gender. Before sentencing, significant gaps emerge in the severity of pretrial release conditions that disadvantage black and Hispanic defendants. Yet when prosecutors decide whether to pursue charges, we observe an initial correction mechanism: Hispanic men are almost two-thirds more likely to have those charges dropped relative to white men. Although few cases survive after the plea bargaining stage, a second correction mechanism arises: Hispanic men are substantially less likely to receive harsher sentences and are sent to jail for significantly less time relative to white men. The first mechanism is based, in part, on prosecutors’ reviewing the strength of the evidence, but much more on declining to invest scarce resources in the pursuit of defendants who fail to appear for trial. The second mechanism seems to follow more directly from judicial discretion to reverse decisions made by law enforcement or prosecutors. We discuss possible explanations for these novel empirical results and review methods for more precisely identifying causal mechanisms in criminal justice

Increased neuronal nitric oxide synthase activity in retinal neurons in early diabetic retinopathy

PURPOSE. There are increased levels of nitric oxide (NO) in diabetic retinas. The purpose of this study was to determine the extent that neuronal nitric oxide synthase (nNOS) contributes to the increased levels of retinal NO in early diabetic retinopathy by examining the expression and activity of nNOS in retinal neurons after 5 weeks of diabetes. METHODS. Changes in NO levels were measured using NO imaging of retinal neurons in mice with streptozotocin-induced diabetes for five weeks. NO imaging was compared to nNOS localization using immunocytochemistry, and nNOS message and protein levels were measured using quantitative real-time PCR and western blots. RESULTS. There was a close anatomic correlation between the localization of the increased NO production and the nNOS immunoreactivity in the retinal plexiform layers of diabetic retinas. There was no change in nNOS message, but nNOS protein was decreased and its subcellular localization was altered. Treatment with insulin or aminoguanidine partially ameliorated the increase in NO in diabetic retinas. CONCLUSIONS. These results suggest that increased nNOS activity is responsible for the majority of increased NO in retinal neurons in early diabetic retinopathy. This supports a role for increased nNOS activity in the early neuronal dysfunction in the diabetic retina.National Institutes of Health (NEI EY04785 to WDE

Simulating 50 kev x-ray photon detection in silicon with a down-conversion layer

Simulation results are presented that explore an innovative, new design for X-ray detection in the 20–50 keV range that is an alternative to traditional direct and indirect detection methods. Typical indirect detection using a scintillator must trade-off between absorption efficiency and spatial resolution. With a high-Z layer that down-converts incident photons on top of a silicon detector, this design has increased absorption efficiency without sacrificing spatial resolution. Simulation results elucidate the relationship between the thickness of each layer and the number of photoelectrons generated. Further, the physics behind the production of electron-hole pairs in the silicon layer is studied via a second model to shed more light on the detector’s functionality. Together, the two models provide a greater understanding of this detector and reveal the potential of this novel form of X-ray detection

Flexible structure control laboratory development and technology demonstration

An experimental structure is described which was constructed to demonstrate and validate recent emerging technologies in the active control and identification of large flexible space structures. The configuration consists of a large, 20 foot diameter antenna-like flexible structure in the horizontal plane with a gimballed central hub, a flexible feed-boom assembly hanging from the hub, and 12 flexible ribs radiating outward. Fourteen electrodynamic force actuators mounted to the hub and to the individual ribs provide the means to excite the structure and exert control forces. Thirty permanently mounted sensors, including optical encoders and analog induction devices provide measurements of structural response at widely distributed points. An experimental remote optical sensor provides sixteen additional sensing channels. A computer samples the sensors, computes the control updates and sends commands to the actuators in real time, while simultaneously displaying selected outputs on a graphics terminal and saving them in memory. Several control experiments were conducted thus far and are documented. These include implementation of distributed parameter system control, model reference adaptive control, and static shape control. These experiments have demonstrated the successful implementation of state-of-the-art control approaches using actual hardware
