title: Viscous dissipation in 3D spine reconnection solutions

authors: Craig, Ian J.D.

subjects: Science & Technology

abstract: Aims. We consider the influence of viscous dissipation on “spine” reconnection solutions in coronal plasmas. It is known from 2D and 3D “fan” reconnection studies that viscous losses can be important. We extend these arguments to 3D “spine” reconnection solutions. Methods. Steady 3D spine reconnection models were constructed by time relaxation of the governing visco-resistive MHD equations. Scaling laws were derived that compare the relative importance of viscous and resistive damping. Results. It is shown that viscous dissipation in spine reconnection models can dominate resistive damping by many orders of magnitude. A similar conclusion, but with less severe implications, applies to current sheet “fan” solutions. These findings are not sensitive to whether classical or Braginskii viscosity is employed.

title: Turning marketing promises into business value: The experience of an industrial SME

authors: Little, Victoria

subjects: customer relations

abstract: The article studies the value that businesses should have for their customers and shareholders. It explains how to develop such value to meet or exceed customer's expectations through the application of the promise framework. The promise model includes promises made to customers, promises kept, and promises that involve a synchronized effort from the whole firm to create and deliver value to customers.

title: Māori women in Southern New Zealand’s shore-whaling world

authors: Stevens, Kate

abstract: Kate Stevens and Angela Wanhalla explore the role of Māori women in Southern New Zealand’s nineteenth-century shore-whaling world. Rarely noted in accounts of the industry, Māori women were adept at sea travel and maintained knowledge and beliefs that informed practices of the whaling communities located on Kāi Tahu tribal territory. Highlighting their role as intermediaries between humans and the marine world, Wanhalla and Stevens bring forth several historical accounts of Māori women involved in the shore-whaling industry.
