Public goods theories highlight an incentive system that rewards ‘free riding’ on the contributions of early contributors toward collective actions. However, because such theories focus on creation of the good, they may underestimate returns that accrue to early contributors subsequent to the good's realization. The concept of formative investment is introduced here to describe the extent to which organizations help to create public goods such as interorganizational linkages like participatory federations. Data from the CEOs of 48 organizations involved in a participatory federation were used to assess how an organization's level of formative investment is related to later patterns of dependency and interaction among federation members. Findings suggest that from a long‐term perspective, and for goods that involve communication and interaction, the incentive structure may not be so favorable for free riders. To the extent that organizations with high formative investment have the capability to envision the future and communicate that vision to potential federation partners, they may be able to both reduce free riding and secure for themselves advantageous positions in the subsequent network of relations.  相似文献

The token economy has been the primary model for the behavioral management of inpatient populations. However, this basically operant approach seldom emphasizes the development of cognitive-coping skills to help patients more effectively manage stressors that result in hospitalization. The Therapeutic Contract Program (TCP) is described as an inpatient-treatment strategy that is designed to help foster such cognitive-coping and self-control skills. While external structure is provided by components of this program, subprograms of the TCP have as their goal the development of internally-attributed coping skills and self-perceptions of competence. This preliminary report describes the structure of the TCP, as well as planned and in-progress measures of program participation and treatment outcome.  相似文献

In this article, an investigator who is outside of the connectionist / dynamic systems (CD) tradition, but is sympathetic to many of its theoretical stances, considers whether these are separate approaches and what the two approaches mean for the development of information processing. It is argued that these approaches have not been defined in the target articles of this special issue narrowly enough to make them clearly separate approaches. Rather, they appear to emphasize different aspects of a common approach. It is also suggested that they do not form an overarching theory of development but do form an important theoretical approach at one level of analysis. In particular, one may sometimes, but not always, have to get into nonlinear interactions between faculties of the mind to predict and explain behavior. Finally, an attempt is made to challenge the CD approach to become more global by confronting the issue of how attention and conscious awareness should be represented in these models, and how the development of them may occur. Evidence of changes in automatic and attention-related parameters of processing may provide a scaffolding upon which better CD models can be constructed.  相似文献
