Consistency and its converse: an introduction

This essay is a didactic introduction to the literature on the “consistency principle” and its “converse”. An allocation rule is consistent if for each problem in its domain of definition and each alternative that it chooses for it, then for the “reduced problem” obtained by imagining the departure of an arbitrary subgroup of the agents with their “components of the alternative” and reassessing the options open to the remaining agents, it chooses the restriction of the alternative to that subgroup. Converse consistency pertains to the opposite operation. It allows us to deduce that a rule chooses an alternative for a problem from the knowledge that for each two-agent subgroup, it chooses its restriction to the subgroup for the associated reduced problem this subgroup faces. We present two lemmas that have played a critical role in helping understand the implications of these properties in a great variety of models, the Elevator Lemma and the Bracing Lemma. We describe several applications. Finally, we illustrate the versatility of consistency and of its converse by means of a sample of characterizations based on them.     

Exploring accounting-sustainability hybridisation in the UK public sector

The transformative potential of accounting-sustainability hybrids has been promoted and problematized in the literature. We contribute to this debate by exploring, theoretically and empirically, the role of accounting in shaping and reshaping sustainability practices. We develop a holistic framework which we use to analyse the governing and mediating roles of accounting-sustainability hybrids in the Environment Agency (of England and Wales) and West Sussex County Council. Our analysis identifies that local accounting-sustainability hybrids contribute positively to improving eco-efficiency, have some impact on eco-effectiveness, but limited bearing on social justice. Emerging assemblages of accounting-sustainability hybrids create capacity for wider sustainability transformations, particularly through their mediating roles. However, a number of factors combine to frustrate further sustainability transformations within these organisations and those they are charged with governing. These factors include the structural constraints of the accounting-sustainability hybrids, influenced by a relatively weak local sustainability programmatic and the pressing need to meet increasing service delivery expectations in a period of severe resource constraints.     

Non-user preference for improvements,and attitude towards future use of a bus system

This study was designed to determine transit non-user preferences towards improvements of the bus system in the Milwaukee area. The study was undertaken at the time when the bus system was still privately owned. Pare increase, reduction of service and decline in ridership has been the path, for the private system, to stay in operation. Public acquisition of the system was being contemplated at the time of the study and was finally consummated in July of 1975, when Milwaukee County acquired the system.A questionnaire was distributed by mail to four study areas in Milwaukee, Wisconsin. The study areas all had existing bus service; however, their population constituted a majority of non-users for work trips. The study queried the non-user of the “most desired improvement,” instead of the use of a preference scale to assess the need for improvements, and to measure the impact of improvements on ridership.This study concluded that a potential market does exist amont non-users-approximately 40% being likely to use an improved system. In addition, a systematic relationship does exist between the areas of residence and the respondent's major preference in system improvement, giving rise to a desired improvement profile in each area.The study has also explored the factors which contribute to the willingness of the commuter to change mode and use an improved bus system.     

Strategic integration of HRM and firm performance in a changing environment in China: the impact of organisational effectiveness as a mediator

In the context of dramatic changes in China, this paper investigates the role of organisational effectiveness as a mediator in the relationship between the strategic integration of human resource management (HRM) and firm financial performance. Our study is based on the survey responses of 618 managers in state-owned and private (domestic and foreign-invested) enterprises in China. While most studies of the linkage between HRM practices and firm performance in China have measured firm financial performance or used an ad hoc combination of financial and non-financial indicators, we argue for a distinction to be made between non-financial organisational effectiveness and financial performance. As hypothesised, controlling for sector (state-owned vs. private), we find positive relationships between perceived changing business environment and strategic integration of HRM, and between strategic integration of HRM and organisational effectiveness. Our research adds an important conceptual link by showing that organisational effectiveness plays an important role as a mediator in the HRM and firm financial performance relationship and reinforces the importance of the organisational and environmental context for HRM.     

Operators for the adjudication of conflicting claims

We consider the problem of allocating some amount of an infinitely divisible and homogeneous resource among agents having claims on this resource that cannot be jointly honored. A “rule” associates with each such problem a feasible division. Our goal is to uncover the structure of the space of rules. For that purpose, we study “operators” on the space, that is, mappings that associate to each rule another one. Duality, claims truncation, and attribution of minimal rights are the operators we consider. We first establish a number of results linking them. Then, we determine which properties of rules are preserved under each of these operators, and which are not.
