Ambidextrous Leadership

PurposeThis study seeks to provide a narrative literature review of existing empirical research, in order to better understand the processes and theory of ambidextrous leadership, as well as its influence on followers, employees and organizations.Design/methodology/approachData from 26 studies were extracted and synthesied providing a critical discussion about the methodological and theoretical aspects of the studies identified in the review.FindingsIt was revealed the attributes for an effective ambidextrous leader, it was presented the recently proposed concept of ambidextrous leadership theory and it was noticed the main criticisms against the findings of the extant ambidextrous leadership literature. It was also identified many research gaps in the literature which in turn can guide academics in the development of ambidextrous leadership.Research limitations/implicationsThe ambidextrous leadership theory represents a novel and unique approach to the domain of leadership for creativity and innovation. It is shared across hierarchical levels throughout the organization. Leaders have a significant effect on employees' behaviors and should determine its applicability to different situations. Organizations require ambidextrous managers who combine flexible, situational and versatile leadership styles developing ever increasingly new and divergent ideas. Many research gaps in the literature were also identified that can guide academics in the development of ambidextrous leadership.Practical implicationsUnderstanding that ambidextrous leadership is required to significantly influence ambidexterity and innovation allows organizations to direct their leadership selection and development.Originality/valueThis review contributes to the ambidextrous leadership literature by creating a holistic picture of where it has been and where it should go.

Ambidextrous Leadership

The aim of the study is to examine the relationships between ambidextrous leadership behaviors (i.e., task-oriented, relation-oriented, change-oriented, and external) in the context of leader behavior level and employee ambidextrous performance (i.e., exploitation and exploration) in the context of individual employee level by suggesting that the interaction of these two may result in organizational ambidexterity. This study aims to contribute to the immature ambidexterity literature by developing some propositions based on the previous ambidexterity researches related to ambidexterity of leaders, employees, and entire organizations. Taking into account ambidextrous leadership theory, it is proposed that while the leaders' task-oriented and relation-oriented behaviors are positively related to the employees' exploitation behaviors, the leaders' change-oriented and external behaviors are positively related to the employees' exploration behaviors. It is recommended for further studies to investigate the possible propositions with quantitative research designs.

Resolution Level

The use of thick specimens (0.5 μm to 5.0 μm or more) is one of the most resourceful applications of high-voltage electron microscopy in biological research. However, the energy loss experienced by the electron beam in the specimen results in chromatic aberration and thus in a deterioration of the effective resolving power. This sets a limit to the maximum usable specimen thickness when investigating structures requiring a certain resolution level.An experimental approach is here described in which the deterioration of the resolving power as a function of specimen thickness is determined. In a manner similar to the Rayleigh criterion in which two image points are considered resolved at the resolution limit when their profiles overlap such that the minimum of one coincides with the maximum of the other, the resolution attainable in thick sections can be measured by the distance from minimum to maximum (or, equivalently, from 10% to 90% maximum) of the broadened profile of a well-defined step-like object placed on the specimen.

Abstract: Neuroplasticity research in connection with mental disorders has recently bridged the gap between basic neurobiology and applied neuropsychology. A non-invasive method in the gerbil (Meriones unguiculus) - the restricted versus enriched breading and the systemically applied single methamphetamine dose - offers an experimental approach to investigate psychoses. Acts of intervening affirm an activity dependent malfunctional reorganization in the prefrontal cortex and in the hippocampal dentate gyrus and reveal the dopamine position as being critical for the disruption of interactions between the areas concerned. From the extent of plasticity effects the probability and risk of psycho-cognitive development may be derived. Advance may be expected from insights into regulatory mechanisms of neurogenesis in the hippocampal dentate gyrus which is obviously to meet the necessary requirements to promote psycho-cognitive functions/malfunctions via the limbo-prefrontal circuit.
