Common leadership strategies and practices among authentic senior leaders

From the early 2000s onwards, authentic leadership has continued to garner growing interest from academia, the public sector, and across multiple industries. Perhaps the reason for the increased focus on authenticity is the unethical behavior demonstrated by a number of leaders from 2000 to 2010. While there is growing interest in demonstrating authenticity as a situational leadership style or even an inherent trait, there is limited research on what leadership strategies or practices are most effective for authentic leaders. This study was designed to apply a common definition, or set of criteria, to identify leaders that are authentic. Once this group of authentic leaders has been identified, research can be conducted to understand common characteristics, traits, styles, practices, and strategies. Conversely, the opportunity exists to understand what common challenges authentic leaders face to determine mitigation strategies. The findings of this study provided exemplary best practices for leaders in business and other fields. To help ground the study, a detailed literature review of leadership theory, and authentic leadership’s place within the study of leadership, was completed. The historical examination of leadership is important as it adds richness and context to how authenticity has risen to prominence within empirical and theoretical research. This research showed that common leadership strategies and practices among authentic leaders include the ability to connect and engage through honest and transparent storytelling. Authentic leaders are vulnerable and transparent, and they enable and engage people and organizations through sharing a compelling vision. Their core leadership approach of honesty and transparency does not change, but they will flex how direct they are based on the situation and audience. In terms of challenges, authentic senior leaders have a high desire for their authentic approach to be reciprocated, and they can be too demanding. In order to overcome these challenges, they try to manage their stress and use physiological and mental means to manage energy. Authentic senior leaders measure success in terms of business results, talent development, and being recognized. The advice they have for future leader is to be one’s authentic self and to understand one’s personal mission and purpose

Situational awareness and transparency as core concepts of authentic leadership

There is not a common, agreed upon definition of authentic leadership. There are varying opinions as to whether authenticity is a trait or a style; however, most scholars believe authenticity is a purpose and value based characteristic (Gardner, Cogliser, Davis, & Dickens, 2011) that is developed over time (George, 2003). Transparency is a core concept of authentic leadership, and situational awareness is a critical skill for leaders to determine the degree of transparency that they should demonstrate. There is limited theoretical and empirical research on how transparency and self-monitoring can be used in conjunction with situational leadership and situational awareness theory. This study measures the impact of a leader\u27s expression of transparency on follower\u27s confidence in his or her ability with consideration of a number of covariates. The findings of this study are intended to help advance authentic leadership theory with specific focus on situational awareness and transparency as core concepts of authenticity. Implications are discussed on the advancement of leadership theory, authentic leadership, and transparency as a core concept of authenticity. Data collection used Amazon Mechanical Turk (MTurk) and yielded 1,006 global participants who met the inclusion criteria. In general, higher degrees of leadership transparency yield higher levels of follower confidence. Situation can impact how expressions of transparency impact follower confidence. Thus, situational awareness and situational leadership are critical competencies for leaders to use transparency effectively. Leader-Member Exchange does not, generally, moderate the relationship between a leader\u27s transparency and his or her follower\u27s confidence. There was statistical significance in the difference in responses between confidence. There was statistical significance in the difference in responses between geographies, but there were not statistically significant differences in the results when considering gender, years of work experience, education, age, and race in the US

Charged particle beam acceleration and strong discharge currents' fields generation by laser - a study on laser-driven ion sources and beam transport suited for application in high-energy-density physics experiments

This work aims at both, the experimental benchmark of laser-driven ion acceleration from targets in the near-critical density regime and the exploration of laser-driven open-geometry platforms for spatial and spectral ion beam tailoring. Theoretically described mechanisms and dynamics predicted by numerical simulations are compared to novel experimental findings that are supported by new particle in cell simulations and heuristic models. Results comprise (i) demonstration of Helium ion acceleration from ultra-relativistic laser-driven near-critical density gas jet targets employing shock nozzles, (ii) further investigation of the driving mechanisms of charged particle beam lensing platforms in the quasi-static regime driven by ns-laser and in the transient regime driven by sub-ps laser, and (iii) studies of transport and tailoring of laser accelerated particle beams by electromagnetic and magnetic fields. The Helium ion source shows cut-off energies above 55MeV, a regime suitable for isotope production in alpha-therapy. Hence, the destruction of nozzles in the violent experimental environment and the perspective to high-repetition-rate operation underlines the need of mass producible nozzles with automatized nozzle exchange and vacuum systems able to maintain good vacuum levels. Ns-laser driven magnetic lenses show comparable current amplitudes in the spontaneous magnetic fields of the plasma and the consumer loop, which favors the theoretical modeling of the platform as a plasma-diode power source. During the laser drive, space charge effects arise with the arrival of the laser-plasma in vicinity of the magnetic lens, representing a possible threat to efficient lensing of ion beams. A modified target geometry is presented that decreases space charge effects. Short laser-pulse driven solid target discharge gives rise to a surficial pulsed potential dynamics guided by the target geometry. This work shows that electromagnetic discharge pulses emanating the interaction region are followed by a pulse discharge current from the ground, both transporting kA-range currents through the target rod. The observed pulsed current dynamics on timescales of tens of ps indicates the presence of a hot surface plasma. The temperature and electron density of the surface plasma are promising control parameters of the discharge pulse dispersion. The high branch of the dispersion relation is responsible for a group velocity different from the speed of light. Solutions on the low branch of the dispersion relation agree with modulations of the target potential in their spatial dimensions and temporal growth rate. Experimental and numerical studies of short laser pulse driven platforms show their applicability to spectral shaping of ion beams, with a perspective to temporal compression of beams for cases where low energy parts of the spectrum get efficiently post-accelerated. Presented are the experimental study of a simple double-coil geometry and a numerical study of a helical coil target. This work motivates junction of presented approaches for future experiments aiming at high repetition rate laser accelerated high energy density ion beams for applications, notably medical isotope production, or fundamental research, ranging from studies on collective stopping effects, warm dense matter generation to an optimized fast ignition particle injector

Latent Heat Flux Profiles from Collocated Airborne Water Vapor and Wind Lidars during IHOP_2002

Latent heat flux profiles in the convective boundary layer (CBL) are obtained for the first time with the combination of the DLR water vapor differential absorption lidar (DIAL) and the NOAA high resolution Doppler wind lidar (HRDL). Both instruments were integrated nadir viewing on board the DLR “Falcon” research aircraft during the International H2O Project (IHOP_2002) over the U.S. Southern Great Plains. Flux profiles from 300 – 2500 m AGL are computed from high spatial resolution (150 m horizontal and vertical) two-dimensional water vapor and vertical velocity lidar cross sections using the eddy covariance technique. All cospectra show significant contributions to the flux between 1 and 10 km wavelength, with peaks between 2 and 6 km, originating from large eddies. The main flux uncertainty is due to low sampling (55 % rmse at mid-CBL), while instrument noise (15 %) and systematic errors (7 %) play a minor role. The combination of a water vapor and a wind lidar on an aircraft appears as an attractive new tool that allows measuring latent heat flux profiles from a single over-flight of the investigated area

Global business services

Purpose – The purpose of this paper is to explore the contribution of global business services to improved productivity and economic growth of the world economy, which has gone largely unnoticed in service research. Design/Methodology/Approach – The authors draw on macroeconomic data and industry reports, and link them to the non-ownership concept in service research and theories of the firm. Findings – Business services explain a large share of the growth of the global service economy. The fast growth of business services coincides with shifts from domestic production towards global outsourcing of services. A new wave of global business services are traded across borders and have emerged as important drivers of growth in the world's service sector. Research Limitations and Implications – This paper advances the understanding of non-ownership services in an increasingly global and specialized post-industrial economy. The paper makes a conceptual contribution supported by descriptive data, but without empirical testing. Originality/Value – The authors integrate the non- ownership concept and three related economic theories of the firm to explain the role of global business services in driving business performance and the international transformation of service economies

Conventionalisation and discrimination as competing pressures on continuous speech-like signals

© John Benjamins Publishing Company. Arbitrary communication systems can emerge from iconic beginnings through processes of conventionalisation via interaction. Here, we explore whether this process of conventionalisation occurs with continuous, auditory signals. We conducted an artificial signalling experiment. Participants either created signals for themselves, or for a partner in a communication game. We found no evidence that the speech-like signals in our experiment became less iconic or simpler through interaction. We hypothesise that the reason for our results is that when it is difficult to be iconic initially because of the constraints of the modality, then iconicity needs to emerge to enable grounding before conventionalisation can occur. Further, pressures for discrimination, caused by the expanding meaning space in our study, may cause more complexity to emerge, again as a result of the restrictive signalling modality. Our findings have possible implications for the processes of conventionalisation possible in signed and spoken languages, as the spoken modality is more restrictive than the manual modality

Recommendations for Standards of Network Care for Patients with Parkinson’s Disease in Germany

Although our understanding of Parkinson’s disease (PD) has improved and effective treatments are available, caring for people with PD remains a challenge. The large heterogeneity in terms of motor symptoms, nonmotor symptoms, and disease progression makes tailored individual therapy and individual timing of treatment necessary. On the other hand, only limited resources are available for a growing number of patients, and the high quality of treatment cannot be guaranteed across the board. At this point, networks can help to make better use of resources and improve care. The working group PD Networks and Integrated Care, part of the German Parkinson Society, is entrusted to convene clinicians, therapists, nurses, researchers, and patients to promote the development of PD networks. This article summarizes the work carried out by the working group PD Networks and Integrated Care in the development of standards of network care for patients with PD in Germany

Resonant Regeneration in the Sub-Quantum Regime -- A demonstration of fractional quantum interference

Light shining through wall experiments (in the optical as well as in the microwave regime) are a powerful tool to search for light particles coupled very weakly to photons such as axions or extra hidden sector photons. Resonant regeneration, where a resonant cavity is employed to enhance the regeneration rate of photons, is one of the most promising techniques to improve the sensitivity of the next generation of experiments. However, doubts have been voiced if such methods work at very low regeneration rates where on average the cavity contains less than one photon. In this note we report on a demonstration experiment using a microwave cavity driven with extremely low power, to show that resonant amplification works also in this regime. In accordance with standard quantum mechanics this is a demonstration that interference also works at the level of less than one quantum. As an additional benefit this experiment shows that thermal photons inside the cavity cause no adverse effects.Comment: 14 pages, 5 figure
