Governance Restructuring and Transformation in International Associations

In 2005, a survey was conducted of international trade association CEO’s who had, since 2000, successfully navigated governance restructuring and overall transformation (membership structure, IT infrastructure, services, branding, fees, etc.) – in partnership with their board chair. Those surveyed believed that strategic planning, though necessary to improve association performance, was no longer sufficient. Their assumption was that changes in governance structure – as part of an overall transformation initiative – would increase capacity for more nimble responses to corporate members, who described being under increasing pressure to make rapid changes on behalf of their own customers. While testing for success in improving association performance was not the focus of this study – those leaders who succeeded with planned change pointed to more satisfied members. The study does describe the types of governance changes made, as well as provide a post hoc analysis of success factors for developing buy-in for both governance and transformation changes. In general, governance changes included a shift from large congressional structures to smaller trustee groups with emphasis on board policy – to clarify high level ends and bright lines, measure and monitor results, and keep connected to member needs – as recommended by models like Policy Governance®. Across industries and cultures, there appears to be a remarkably consistent pattern for success in developing buy-in for governance change (five key success factors). In addition, the experience of leaders points to a remarkably consistent sequence of steps (three stages) for completion of the transformation process. The analysis and the specific recommendations of those interviewed provide a guide for association leaders currently considering governance restructuring and transformation. Stepping back, a model emerges of a governance framework and a transformation framework that also offers potential for association members to take back to their home corporations. In the U.S. in particular, where innovations in organizational structure and governance are a part of the heritage – a voluntary commitment to robust governance, leadership and transformation can be differentiating for 21st century organizations. Supported by a growing body of evidence pointing to effective governance as enabling stewardship, ethical behavior and integrity, adaptability, and the bottom line – associations that successfully improve governance are ahead of the curve. They’re leaders in improving the integrity and sustainability of their association and their corporations – contributing to the global credibility of open markets and liberal constitutional democracy.

Forgiveness, Cognitive Restructuring and Object Transformation

Forgiveness is described as a process that includes (1) re-constructing cognitions about the offender and self and (2) re-imaging the offender and re-experiencing self and violator. Object relations theory can help to show that the violated individual’s conflict is within as the person struggles inwardly with hostile images (object-representations) during the process of forgiveness. Cognitive restructuring points to the crucial importance of choice to help initiate the forgiveness process. Within the context of forgiveness as a therapeutic process, cognitive restructuring and object transformation can promote the client’s psychological health and well-being. It is proposed that forgiveness is a spiritual as well as a psychological process, which includes grace-filled choices and behavior.

Local state restructuring and urban transformation in post-apartheid Cape Town

This paper analyzes processes of state restructuring at the scale of the local state and the city, exploring the social and political relationships generated through processes of reconstruction specifically in Elsies River, a formerly segregated `coloured' neighborhood in Cape Town. While the relationship between Elsies River residents and the local state has been characterized by an obsessive focus on housing debt, I examine the ways in which antagonism over housing problems overlie a broader relational disjuncture between neighborhood and state political and social networks. The specificity of this case provides a lens onto the ways in which processes of state restructuring both contest and reinforce racial, economic, and place-based inequalities in South African cities. The paper concludes by using the complexities of local state-neighborhood relationships in the South African case to reflect on geographical theories of state-society relations on a conceptual level.

EXTENSIONS TO CYCLE SHRINKING

An important part of a parallelizing compiler is the restructuring phase, which extracts parallelism from a sequential program. We consider an important restructuring transformation called cycle shrinking [5], which partitions the iteration space of a loop so that the iterations within each group of the partition can be executed in parallel. The method in [5] mainly deals with dependences with constant distances. In this paper, we propose certain extensions to the cycle shrinking transformation. For dependences with constant distances, we present an algorithm which, under certain fairly general conditions, partitions the iteration space in a minimal number of groups. Under such conditions, our method is optimal while the previous methods are not. We have also proposed an algorithm to handle a large class of loops which have dependences with variable distances. This problem is considerably harder and has not been considered before in full generality.

LARGE CHINESE CITIES: A REVIEW AND A RESEARCH AGENDA

Recent economic restructuring and spatial transformation in China have provided great opportunities for research. This paper reviews the recent progress in the study of large Chinese cities. It discusses four important issues: urban policy, migration, urban economy, and spatial structure. It also provides a research agenda for further investigations.

Direct update of data flow representations for a meaning-preserving program restructuring tool

Automated assistance for meaning-preserving global restructuring is an approach for helping software engineers improve the structure of programs, thus lowering the costs of maintenance. The consturction of a restructuing tool encounters many conflicting goals---such as simplicity. extensibility, and good performance---that cannot be met without some compromise. In particular, the current technique for assisting restructuring uses a costly program representation---a Program Dependence Graph (PDG) with alias information---that is not practical to recompute from scratch after each restructuring transformation. There are at least two possible solutions. A commonly suggested approach for efficiently updating data flow representations is to use a generic incremental algorithm that does not make use of the special nature of the restructuring. This approach is general, but it does not yet handle aliasing fully. By taking advantage of the special nature of the restructuring transformations it is possible to implement a more efficient update than generic update that also handles aliasing. The idea is to implement direct updates to the PDG that are analogous to the changes on the program text. The downsides to direct update are that it is application-specific, applies only to semantically restricted applications like restructuring, and may be more complex. The choice between the two techniques requires an understanding of the current and future needs of the tool's users.This paper describes the direct approach of updating the PDG and related representations for restructuring, provides techniques for managing its complexity, critiques its advantages and shortcomings relative to generic incremental update, and presents performance results.

The Dual City as Political Choice

ABSTRACT: This paper examines the proposition that the dual social character of urban America is mostly a product of US political choices during this century. In responding to the emerging imperatives of economic restructuring and racial transformation, federal, state, and local officials pursued a Jeffersonian notion of urban politics. The author argues that this response has diminished the nation's political capability for achieving community-building solutions to public problems in local politics, thereby creating more polarized metropolitan areas.

Parallel Scheduling of Recursively Defined Arrays: Revisited

A restructuring transformation is described which can be used to parallelize recurrence relations. The transformation is based on the hyperplane (or wavefront) method, but extends the applicability of the method to irregularly structured recurrences and introduces an algorithm for solving a restricted class of symbolic linear inequalities which arise from such irregularly-structured recurrences. The algorithm for solving this class of linear inequalities is also of general interest to symbolic computing with systems of linear inequalities. Various sub-problems which arise include deciding systems of linear inequalities, finding the set of extreme points and extreme directions of a convex polyhedron, identifying implicit equalities, and eliminating redundant inequalities. Some approaches to these sub-problems are discussed and a sub-algorithm is given for each.

Critical point estimates for the spin s Ising model from the high temperature series renormalisation group method

Abstract By prefacing the high temperature series renormalisation group transformation with a spin restructuring transformation, estimates of the critical point of the spin s Ising model on the square and triangular lattices have been obtained. The systematic nature of the high temperature series method is preserved and the accuracy of the estimates appears to be principally dependent on the accuracy with which the s = 1 2 critical point is determined.
