THE LAST MILE: AN EXAMINATION OF EFFECTS OF ONLINE RETAIL DELIVERY STRATEGIES ON CONSUMERS

The Internet has increased the level of importance of the end‐consumer market to transportation carriers. In two between subject experiments, carrier disclosure on retail merchant websites is examined as a strategic differentiation strategy. Predictions are offered concerning effects of carrier disclosure strategies on product delivery‐related expectations, consumer attitudes, and intentions to purchase a product online. Results from Study 1 reveal significant differences between disclosure and nondisclosure of the carrier for numerous product delivery‐related variables, as well as many differences between the six carriers examined in this first study. Study 2 extends these findings by showing that providing consumers with a choice of carrier leads to increased levels of satisfaction with the online experience and greater willingness to buy, relative to nondisclosure and disclosure strategies.     

Infrastructure investment on the margins of the market: The role of niche infrastructure providers in the UK

Across Europe, policymakers and market forces are striving to deploy next generation access (NGA) networks and ensure ubiquitous access to superfast broadband services. Due to scale economies and sunk costs, the roll-out of NGA is expected to be profitable only for large-scale providers and in densely populated areas. Nonetheless, alternative providers, such as utilities and local communities, have significantly contributed to NGA diffusion in many countries. Over the past five years, several small-scale initiatives have emerged in the UK, bringing fibre networks to urban and rural areas previously overlooked by either commercial or subsidised deployments. A multiple case study approach is employed here to explore the nature and the drivers of niche providers in the UK NGA market. All these initiatives are demand-driven and to follow a modular approach. Despite adopting different business models, they all rely on the resources inherited from past broadband initiatives and relationships with local partners. By investigating the strategies of niche providers in NGA market, this analysis sheds light on their contribution to bridging the digital divide in the UK and is presented as a preliminary assessment of their sustainability and potential growth.     

非现金支付结算对现金流通的影响研究

近年来,随着支付基础设施的不断建成和完善、支付服务组织的健全以及社会信用的发展,非现金支付结算工具的推广应用越来越广泛。本文从理论和实证两个方面研究了非现金支付结算工具的发展对区域现金流通的影响,探索非现金支付结算对流通中现金影响的传导途径,创造性地使用现金结算量作为现金流通状况的测度指标,在进行多元线性回归分析后,采用向量自回归模型(VAR)探讨各类非现金支付工具发展对现金流通的影响程度,认为非现金支付结算方式对现金的替代效果不明显。在对此进行原因分析的基础上,本文得出"增量替代"效应的新思路。     

安全活动对物流企业绩效作用的实证分析

本文以物流企业为调查对象进行问卷调查,通过Bootstrapping和结构方程模型的路径分析,分析了物流安全活动对成本控制,运输效率和企业绩效之间的影响关系.同时,以路径分析结果为基础,提出了推广物流安全实践活动和提高物流企业绩效的意义.结果表明,安全运输实践及安全运输预防管理对成本控制和运输效率都有着显著的积极影响,运输手段安全管理对成本控制有着显著的积极影响,而运输手段安全管理对运输效率产生的影响力在5％的显著性水平下不显著,成本控制对运输效率也产生了显著的积极影响关系,成本控制和运输效率对企业绩效也都有着显著的积极影响.

以非线性理论阐述反馈振荡器的频率与幅度的稳定性

本文首先对线性的频率稳定理论用于近似正弦反馈振荡器的线性频率稳定理论,进行了评论性的回顾。在这方面,解释所谓的线性振荡器是清楚的。其后,是应用描述函数法和判决方程法所得到新的表达式,去阐述反馈振荡器考虑成一个非线性网络时的振荡频率和振荡幅度的稳定性。     

Small enterprises as complex adaptive systems: a methodological question?

Complexity science constitutes an emerging post-positivist interdisciplinary field of investigation of dynamical systems in the natural and physical worlds. The central concept of complexity is that interactions between parts of open systems create novel, unpredictable patterns, and that while the history of the system is relevant in understanding its dynamic, the isolation of individual parts of the system (analysis) does not reveal the casual mechanisms in the system. It is suggested that complexity science can inform our methodologies for investigating the social sciences. The paper explores whether complexity science offers ways of theory building that can take account of pluralistic or interdisciplinary research in enterprise dynamics. The authors offer a model of six theorized ontological layers, derived from the canon of research literature within a small enterprise domain, with boundaries at each end. It is suggested that dynamical concepts of agency (adaption, evolution, fitness, interdependence) coupled with the theory of evolutionary autopoietic structures generate a plausible field for the study of enterprise dynamics. A focus on ontological and experimental adequacy is necessary to develop theory within this framework. An appropriate methodology involves iterations between experimental forms of scientific analysis and the grounding of emergent or evolving theories.     

从A123破产看美国支持新兴产业政策的失灵

2009年,美国政府宣布在经济复苏法案中拨款24亿美元支持电动汽车电池产业的发展,生产锂电池的A123系统公司获2.49亿美元拨款。A123虽获美国政府新兴产业政策的大力支持,但在美国能源法案关于资金用途的约束下,从辉煌走向崩塌,于2012年申请破产。A123的破产启示我们:政府培育新兴产业的政策要在尊重市场规律的前提下突出产品创新,提高产品的技术含量和成熟度;在新兴产业的发展过程中,最关键的是产品的技术含量,而对资金、人力资源起基础配置作用的是市场,若忽视产品的技术完善,背离市场规律,尽管政府扶持政策力度很大,也会出现政策失灵。
