Putting the voluntary sector in its place : geographical perspectives on voluntary activity and social welfare in Glasgow.

The growing political and social significance of the voluntary sector in contemporary welfare reform is reflected in a wide body of research that has emerged in the political and social policy literature since the mid-1980s. While this work adds considerably to our understanding of the changing role of the voluntary welfare sector, these accounts are largely aspatial. Yet, geographical perspectives offer important insights into the development of the voluntary sector at both micro-and macro-levels. The purpose of this paper is thus twofold: first we wish to draw attention to what it is that geographers do that may be of interest to those working in the field of social policy; and second, we illustrate why such perspectives are important. Drawing on recently completed work in Glasgow, we demonstrate how geographical approaches can contribute to a greater understanding of the uneven development of the voluntary sector across space and how voluntary organisations become embedded in particular places. By unravelling some of the complex webs of inter-relationships that operate across the geographical and political spaces that extend from national to local we reveal some unique insights into those factors that act to facilitate or constrain the development of voluntary activity across the city with implications for access, service delivery and policy development. Hence, we maintain, that geographical approaches to voluntarism are important for social policy as such approaches argue that where events occur matter to both their form and outcome

High-beta turbulence in two-dimensional magnetohydrodynamics

Incompressible turbulent flows were investigated in the framework of ideal magnetohydrodynamics. Equilibrium canonical distributions are determined in a phase whose coordinates are the real and imaginary parts of the Fourier coefficients for the field variables. The magnetic field and fluid velocity have variable x and y components, and all field quantities are independent of z. Three constants of the motion are found which survive the truncation in Fourier space and permit the construction of canonical distributions with three independent temperatures. Spectral densities are calculated. One of the more novel physical effects is the appearance of macroscopic structures involving long wavelength, self-generated, magnetic fields ("magnetic islands"). In the presence of finite dissipation, energy cascades to higher wave numbers can be accompanied by vector potential cascades to lower wave numbers, in much the same way that in the fluid dynamic case, energy cascades to lower wave numbers accompany entropy cascades to higher wave numbers

A statistical formulation of one-dimensional electron fluid turbulence

A one-dimensional electron fluid model is investigated using the mathematical methods of modern fluid turbulence theory. Non-dissipative equilibrium canonical distributions are determined in a phase space whose co-ordinates are the real and imaginary parts of the Fourier coefficients for the field variables. Spectral densities are calculated, yielding a wavenumber electric field energy spectrum proportional to k to the negative second power for large wavenumbers. The equations of motion are numerically integrated and the resulting spectra are found to compare well with the theoretical predictions

Experiencing Organizational Change During an Era of Reform:Police Scotland, Narratives of Localism, and Perceptions from the ‘Frontline’

In 2011, the Scottish Government took the decision to create a single, national police force, reconfiguring a structure of regional police forces, which had prevailed since the 19th century. Despite a strong narrative around localism in the legislation establishing Police Scotland, the new force that was established in 2013 quickly found itself at the centre of a debate around an emerging ‘crisis of localism’ as critics expressed concerns over the centralization of decision-making and a lack of sensitivity to local contexts. Drawing on qualitative research carried out in four communities across Scotland in 2016, the analysis presented in this article examines the experience of organizational change from the perspective of officers in local policing teams and from local stakeholders. The analysis is structured around the strategic aims of reform of improved local service delivery, more equal local access to specialist expertise, and enhanced connections with local communities. The article highlights the sense of exclusion from the decision-making surrounding the organizational changes associated with the implementation of reform experienced by local, rank-and-file officers

Great Expectations? Assessing the creation of national police organisations in Scotland and the Netherlands

Against a background of recent structural reforms to police organisations in northern and western Europe, this paper examines the experiences of Scotland and the Netherlands where national police forces were established in 2013. Taking a comparative perspective, an analysis of the police reform proposals is followed by a review of the arguments for reform, the challenges of implementation and the findings emerging from the evaluations of the police reforms in each country. The paper concludes by drawing out the contrast between the ‘great expectations’ of the two police reforms articulated by the governments and the realities of bringing about rapid and large-scale organisational change, arguing that institutionalist perspectives on police reform have much to offer in making sense of the challenges of the police reform process

The challenges of change:Exploring the dynamics of police reform in Scotland

Despite a long tradition of pessimism regarding the scope for meaningful change in police practices, recent structural reforms to police organizations in several European countries suggest that significant change in policing is possible. Drawing on recent research into the establishment and consequences of a national police force in Scotland, this article uses instrumental, cultural and myth perspectives taken from organization theory to examine how change happened and with what effects. It highlights how police reform involves a complex interplay between the strategic aims of government, the cultural norms of police organizations and the importance of alignment with wider views about the nature of the public sector. The article concludes by identifying a set of wider lessons from the experience of organizational change in policing

Magnetic dynamo action in two-dimensional turbulent magneto-hydrodynamics

Two-dimensional magnetohydrodynamic turbulence is explored by means of numerical simulation. Previous analytical theory, based on non-dissipative constants of the motion in a truncated Fourier representation, is verified by following the evolution of highly non-equilibrium initial conditions numerically. Dynamo action (conversion of a significant fraction of turbulent kinetic energy into long-wavelength magnetic field energy) is observed. It is conjectured that in the presence of dissipation and external forcing, a dual cascade will be observed for zero-helicity situations. Energy will cascade to higher wave numbers simultaneously with a cascade of mean square vector potential to lower wave numbers, leading to an omni-directional magnetic energy spectrum which varies as 1/k 3 at lower wave numbers, simultaneously with a buildup of magnetic excitation at the lowest wave number of the system. Equipartition of kinetic and magnetic energies is expected at the highest wave numbers in the system
