Journal of Management Studies, EarlyView.Abstract In previous research, scholars have often highlighted the important role of leaders in defending and protecting a historical organizational purpose. However, adopting such a ‘backward‐looking’ perspective, researchers have devoted much less attention to understanding how an organizational purpose can be deliberately changed and leveraged to ...

Clutchless multiple drive source for output shaft [PDF]
A first shaft is connected to a source of rotational power and has a gear fixedly mounted on the shaft. A second gear is fixedly mounted on a gear shaft that is parallel to the first shaft.

Analysis of the Dynamic Load Sharing Characteristic of Two-stage Planetary Transmission
Jixie chuandong, 2016 To study the dynamic load sharing characteristics of two- stage planetary gear train,a translation- torsion coupling dynamics model is established by taking the nonlinear factors like time- varying mesh stiffness,position error,eccentric error,gear ...

The Front‐End of Circular Innovation in Incumbent Firms
Journal of Product Innovation Management, EarlyView.ABSTRACT The Circular Economy introduces ambiguity and complexity when developing products and services, by using materials and resources differently; innovations and related business models thus deviate markedly from those evident in the “linear economy”.

Helicopter transmission arrangements with split-torque gear trains [PDF]
, 1983 As an alternative to component development, the case for improved drive-train configuration is argued. In particular, the use of torque-splitting gear trains is proposed as a practicable means of improving the effectiveness of helicopter main ...

Psychology and Psychotherapy: Theory, Research and Practice, EarlyView.Abstract Purpose Cognitive‐behavioural therapy for psychosis (CBTp) achieves small to modest effect sizes, which invites the question, ‘What clinical modifications might improve outcomes?’ This paper proposes an integration of CBTp with a neuropsychoanalytic approach that in clinical practice might extend the gains achieved by CBTp alone.

Vibration in Planetary Gear Systems with Unequal Planet Stiffnesses [PDF]
An algorithm suitable for a minicomputer was developed for finding the natural frequencies and mode shapes of a planetary gear system which has unequal stiffnesses between the Sun/planet and planet/ring gear meshes.
