This study examines how retailers can use self-service technologies (SST) to increase shopper satisfaction. Using a survey of 188 consumers of a new self-service kiosk launch within a convenience-store (c-store) setting, we examine how such retailers might influence shopper's perceptions of value by better involving customers in the service delivery experience. Our proposed model links classic service operations and marketing design insights to the service-dominant logic perspective of service value co-creation. We find that shoppers perceive enhanced value creation from the new SST when they feel comfortable in their roles and the surrounding service design supports those roles. 相似文献

Many natural resource management researchers have focused either on institutional design and evaluation or on livelihood outcomes per se without explicitly acknowledging and rigorously examining linkages between the two. Thus, a major gap in the current literature on co-management institutional arrangements is the extent to which co-management has strengthened the livelihoods of poor forest-dependent communities. This gap is addressed in this paper by developing and testing an argument that well-designed co-management arrangements have strengthened the livelihood outcomes of poor forest-dependent communities in a Kenyan case study. The hybrid analytical framework developed for this analysis situates Ostrom's (1990) design criteria for co-management institutions in the broader context of the Sustainable Livelihood Framework. It then uses this analytical framework to evaluate the Arabuko-Sokoke Forest Reserve (ASFR) co-management initiative in Kenya, based on a three-step process. First, the paper provides an overview of current institutional arrangements for governance of the ASFR co-management regime. Second, it evaluates the extent to which these governance arrangements can be characterized as devolved collaborative governance, informed by Ostrom's (1990) design principles and; third, it evaluates the extent to which the livelihood outcomes of forest dependent communities that are participants in the co-management project have had their livelihoods strengthened as a result of the ASFR co-management governance arrangements. The paper demonstrates that the institutional arrangements for ASFR co-management are relatively nascent and emerging because the governance arrangements for the ASFR co-management project cannot be characterized as fully devolved de jure collaborative governance. Notwithstanding this, the findings reveal that participant forest-dependent communities in the co-management project had improved livelihoods compared to forest-dependent communities outside the co-management scheme. It is suggested that this is due to the de facto co-management arrangements. 相似文献

To mainstream sustainability, we need to understand the value gained from sustainability by users. We apply a user-centred design methodology to develop an agile, iterative, incremental and reflexive process to understand the sustainability value proposition for Lufthansa City Center travel agents. We analyse the failure of sustainability communications within the online platforms used by these agents and explore why the agents factor out sustainability information during the customer sales process. We identify how agents and customers understand sustainability, and we explore opportunities to co-create sustainability value. Furthermore, we prototype, and then test, methods of empowering travel agents to communicate sustainability to their customers as a value-adding proposition. 相似文献

We study the question of which social choice functions from an abstract type space to a set of outcomes are truthful, i.e., implementable by truthful mechanisms, when utilities are quasi-linear. For convex domains, our main theorem characterizes truthful social choice functions as those satisfying two properties: local weak monotonicity and vortex-freeness. The first of these constrains the function values at any two sufficiently proximal points, while the second asserts that its line integrals around sufficiently small triangular loops must vanish.The characterization implies a local-to-global principle that allows one to deduce truthfulness of a function from its behavior on arbitrarily small neighborhoods of each point. Other consequences include a simple alternate derivation of the Saks–Yu Theorem that weak monotonicity characterizes truthfulness of functions having a convex domain and finite range, and a sufficient condition for constructing truthful functions by “stitching together” truthful subfunctions on different subsets of the domain. 相似文献

Collective lobbying organizations and some big companies acted as cautious partners in the design of the Affordable Care Act of the Obama Administration. In addition to being consulted by government executives, these entities intensively lobbied legislators. The qualitative and statistical analysis I conduct here shows a positive impact of healthcare lobbying. Collective lobbying organizations have a significant impact on lawmaking and complementary lobbying enhances their impact. However, not all (disjointed) lobbying is successful. Perspective-based distortion might explain why organizations lobby on issues against all odds of ever being effective. 相似文献
