title: Human capital flows and regional knowledge: a simultaneous equation approach

authors: Faggian, Alessandra

subjects: human capital flow

abstract: Our paper constructs a simultaneous equation model in order to investigate the relationship between interregional human capital knowledge flows and regional knowledge assets. With the aid of a GIS system, we model the simultaneous relationship between the interregional migration behaviour of British students and graduates from university and into employment, the knowledge assets of the regions, and the regions of employment of the graduates. Our results indicate that after controlling for the human-capital flows of students and graduates, there is little evidence in favour of direct spillovers between university research and regional innovation. Rather, the primary role of the university system appears to be as a conduit for bringing potential high quality undergraduate human capital into a region. We argue therefore that the migration effects of embodied human capital in Great Britain appear far more important than informal university-industry spillovers as an explanation of regional learning effects.

title: The third-order law for magnetohydrodynamic turbulence with constant shear

authors: Wan, Minping

subjects: magnetohydrodynamic (MHD) turbulence

abstract: The scaling laws of mixed third‐order structure functions for isotropic, homogeneous, and incompressible magnetohydrodynamic (MHD) turbulence have been recently applied in solar wind studies, even though there is recognition that isotropy is not well satisfied. Other studies have taken account of the anisotropy induced by a constant mean magnetic field. However, large‐scale shear can also cause departures from isotropy. Here we examine shear effects in the simplest case, and derive the third‐order laws for MHD turbulence with constant shear, where homogeneity is still assumed. This generalized scaling law has been checked by data from direct numerical simulations (DNS) of two‐dimensional (2D) MHD and is found to hold across the inertial range. These results suggest that third‐order structure function analysis and interpretation in the solar wind should be undertaken with some caution, since, when present, shear can change the meaning of the third‐order relations.

title: Māori leaders wellbeing: A self-determination perspective

authors: Roche, Maree A.

subjects: Positive psychology

abstract: This research draws on interviews with 18 Māori leaders from various leadership positions within business, community, political and marae organisations, to garner an understanding of how their leadership roles interact with their own well-being. Analysis of interviews revealed that crosscultural developments in self-determination theory could be gained by incorporating Māori tikanga and values into a model of well-being for Māori leaders. Largely, the principles of tino rangatiratanga (autonomy and self-determination), mana (respect and influence), whānau (extended family), whakapapa (shared history) and whanaungatanga (kin relations, consultation and engagement), were united into a model of leader well-being. This ensured that mātauranga Māori (Māori knowledge) informed our model of Māori leader well-being, while also drawing on the burgeoning Western research in the area of well-being, specifically self-determination theory. Overall, we find that similarities exist with self-determination theory and Māori tikanga and values. However, in contrast to self-determination theory, autonomy and competence are developed within relationships, which means that ‘others’ underpin Māori leaders’ well-being. From this perspective, we present a view of the psychological and well-being resources that Māori leaders draw on to guide them through complex times.
