William P. Racine 《Journal of Leadership Studies》2015,9(3):23-41
The current study examined the retrospective experience of scientists and engineers as they became new unit leaders in science and engineering firms. The goal of the study was to propose a theory that would lead to a better understanding of how scientists and engineers can be successful in their evolution into new leaders. The evolution was considered in the context of Robledo, Peterson, and Mumford's (2012) 3‐Vectors Model to appreciate the situation in which new leaders in scientific and engineering firms find themselves. The evolution was then considered in the perspective of Social Identity Theory to understand the relational development of the scientist or engineer as a new leader. The theory that emerged was that without a sound understanding of both the situation and adaptation of a new sociotechnical identity, achieving success in the leadership role is, at best, uncertain. Identity development and situational understanding are both necessary to facilitate and expedite the transition of scientists and engineers into the new leadership role. The transition from staff‐level scientist to leader can be made more productive through individual and organizational action espoused herein. The implications reveal many aspects of importance for organizations, individuals, researchers, and educators in Science, Technology, Engineering, and Math (STEM) and similar technical disciplines. 相似文献

In this study, we attempt to examine the possibility of emergence of significant fluctuations of the exchange rates in the
future for the candidate EMU countries. In doing so, we estimate the equilibrium rate of the nominal effective exchange rate
for Poland, Hungary, Slovak Republic and Malta through the BEER and PEER approaches. While the PEER-based estimation implies
a large misalignment rate for the Hungarian forint, the BEER-based analysis shows that the present exchange rates of the countries
considered do not deviate significantly from their equilibrium rates. As a consequence, based on BEER analysis, we do not
expect large fluctuations in the effective exchange rates among the currencies considered. Hence, the relevant effective exchange
rates are expected to be relatively stable. As a matter of fact, the entry of those countries into EMU is not expected to
weaken the stability of Euro.

Bank crises in emerging economies have been a feature of the recent global crisis, and their incidence has increased in the
post-Bretton Woods era. This paper investigates the impact of financial globalization on the incidence of systemic bank crises
in 20 emerging markets over the years 1976–2002 using measures of de facto and de jure financial openness. An increase in foreign debt liabilities contributes to an increase in the incidence of crises, but foreign
direct investment and portfolio equity liabilities have the opposite effect. A more liberal de jure capital regime lowers the incidence of banking crises, while a regime of fixed exchange rates increases their frequency.
The results of the econometric analysis is consistent with the experience of East European and central Asian emerging markets,
which attracted a relatively large proportion of capital flows in the form of debt in recent years and have been particularly
hard hit by the global financial crisis. 相似文献

A major component of the United States Environmental Protection Agency's 112(r) Risk Management Program Rule is the evaluation and control of potential public exposures to toxic chemicals. The rule requires identification and evaluation of a worst case accidental toxic release scenario, but provides for the inclusion of passive mitigation systems in modeling the dispersion hazard zones that are to be communicated to the public. These passive mitigation systems can be taken into account in the consequence modeling if they will withstand the initiating event that causes the accidental release and function as intended. This paper discusses several passive mitigation systems that can be designed as an integral part of storage or processing of highly toxic chemicals. These include, but are not limited to, optimizing storage conditions, design of secondary containment, toxic vapor generation control, and enclosure design. The effectiveness of various passive mitigation systems is evaluated using consequence modeling for case studies involving highly toxic chemicals such as phosgene, chlorine, and ethylene oxide. 相似文献

Surprisingly, deterministic time series can generate highly irregular, random-appearing trajectories. These deterministic time series result from nonlinear dynamical systems of differential or difference equations. The random appearance displayed by these systems is called nonlinear dynamical complexity. Properties of nonlinear complex systems include aperiodic random appearance, sensitive dependence on initial conditions and model parameters, and nonstationarity. Experiments involving the operation of simulated business environments and theoretical nonlinear dynamical models for inventory are reviewed to explore motivating factors that can give rise to demand with nonlinear complexities. The experimental and theoretical evidence reviewed indicates that nonlinear complexities in demand have significant implications for inventory management. Thus, researchers and practitioners in inventory management need to consider these properties when choosing inventory management methods. Characteristics of nonlinear dynamical systems and their implications for inventory management are presented in this paper. The use of the Brock, Dechert, and Scheinkman (1987) (BDS) test for nonlinear dependence is demonstrated on actual demand data. 相似文献

Isolation procedures and monitoring techniques for the presence of explosive mixtures proved to be inadequate to prevent an explosion which was initiated by an unexpected ignition source. 相似文献
