New Zealand Public Management in Action: A Case Study of Organizational Performance

A case study of performance issues in the child protection services of New Zealand’s Department of Child Youth and Family (CYF) is used to discuss the effects of the New Zealand public management system on the allocation of public resources, accountability for performance and central steering of a decentralised management system. During the last six years, there have been three major reviews of the Department’s performance. Concerns with performance are rooted in growing public concern at the rate of family violence and child homicide in New Zealand. The case study concludes that control of child protection services by either outputs or outcomes is difficult and that CYF is likely to continue to experience ambiguity and political struggle over its objectives, the use of procedural rules for control rather than performance measurement and limited ability to learn from error because of the conflict over objectives. The general conclusion is that implementation of performance management systems works best where goals are clear and results can be observed, there are known effects of management intervention, and the management and staff of the organisation can learn from experience

Krull-gabriel dimension and the ziegler spectrum

We provide an introduction to the the Krull-Gabriel dimension of a ring, as well as many related ideas. In particular, we outline how Krull-Gabriel dimension relates to the Cantor-Bendixson rank of the Ziegler spectrum and with the Jacobson radical of the module category. We also include a list of examples of rings and categories where the Krull-Gabriel dimension has been calculated

The Logistics of Learning: Strategies for Teaching a Part-Time Graduate Program in Public Management

The only Masters degree programme in public management in New Zealand, established in 1998 at Victoria University of Wellington, is part-time and attracts a broad cross-section of mid-career public managers. Participants in the programme have the same needs as other adult learners, to be able to draw on and reflect upon their own workplace experience in their learning. The demands of the workplace also compete heavily for the time they plan for study. The main challenges for the programme are to meet the needs of the students as adult learners and practitioners, to develop a common approach to learning about public management for participants from very diverse working backgrounds and to provide continuity of learning when classroom sessions are in short blocks separated by several weeks of home study

Purity in compactly generated derivators and t-structures with Grothendieck hearts

We study t-structures with Grothendieck hearts on compactly generated triangulated categories $\mathcal{T}$ that are underlying categories of strong and stable derivators. This setting includes all algebraic compactly generated triangulated categories. We give an intrinsic characterisation of pure triangles and the definable subcategories of $\mathcal{T}$ in terms of directed homotopy colimits. For a left nondegenerate t-structure ${\bf t}=(\mathcal{U},\mathcal{V})$ on $\mathcal{T}$, we show that $\mathcal{V}$ is definable if and only if ${\bf t}$ is smashing and has a Grothendieck heart. Moreover, these conditions are equivalent to ${\bf t}$ being homotopically smashing and to ${\bf t}$ being cogenerated by a pure-injective partial cosilting object. Finally, we show that finiteness conditions on the heart of ${\bf t}$ are determined by purity conditions on the associated partial cosilting object

Cotilting Sheaves over Weighted Noncommutative Regular Projective Curves

We consider the category Qcoh$mathbb{X}$ of quasicoherent sheaves where $mathbb{X}$ is a weighted noncommutative regular projective curve over a field $k$. This category is a hereditary, locally noetherian Grothendieck category. We classify all indecomposable pure-injective sheaves and all cotilting sheaves of slope $infty$. In the cases of nonnegative orbifold Euler characteristic this leads to a classification of pure-injective indecomposable sheaves and a description of all large cotilting sheaves in Qcoh$mathbb{X}$

Morphisms between indecomposable complexes in the bounded derived category of a gentle algebra

In this article we provide a simple combinatorial description of morphisms between indecomposable complexes in the bounded derived category of a gentle algebra.Comment: Introduction re-written to include more explicit statements of main result
