鸭稻共作对水稻植株生长性状与产量性状的影响   总被引:7,自引:0,他引:7  
本研究通过大田小区对比实验,探讨了鸭稻共作对水稻植株生长性状与产量性状的影响效果。研究结果表明,鸭稻共作在一定程度上降低了水稻植株的高度和水稻地上部的生物量,但增大了水稻地下部的生物量和根冠比,有利于水稻地下部根系的发育,并在一定程度上增强了水稻的抗倒伏能力;同时,鸭稻共作能提高水稻中后期叶片的叶绿素a和叶绿素b的含量以及叶绿素a/b值,可防止水稻在后期的过早枯黄与衰败,从而增强水稻叶片光合作用的性能及其持续时间;鸭稻共作还能够促进水稻的有效分蘖,增加水稻的有效穗数和成穗率,减少空(秕)粒数,提高水稻的实粒数和结实率,从而有利于水稻产量的形成。这些研究结果可为鸭稻共作生态技术的生产实践与示范推广提供理论依据。  相似文献

In this article, we review current rationales for policy intervention in innovative activities. Focusing particularly on market and system failure rationales, we disentangle related underlying mechanisms for knowledge exploration and exploitation. We provide a novel contribution to the system failure literature by distinguishing between system-level inertia and inhibited emergence. Our conceptualization of inhibited emergence draws on literatures related to neo-institutional sociology, the social construction of technology, and on organizational cognition and learning literatures, and it presents elemental socio-cognitive mechanisms that influence and direct knowledge exploration and exploitation in innovation systems. We compare related, yet theoretically distinct concepts of market failure, system-level inertia, and inhibited emergence, and show how each addresses distinct coordinative mechanisms and field-level dynamics and related socio-cognitive processes.  相似文献

In this paper we present a detailed synthesis of the development of the Human Genome Project (HGP) from the mid 1980s through 2000, in order to test our hypothesis of “social bubbles”, which claims that strong social interactions between enthusiastic supporters weave a network of reinforcing feedbacks that lead to widespread endorsement and extraordinary commitment by those involved, beyond what would be rationalized by a standard cost-benefit analysis in the presence of extraordinary uncertainties and risks. The HGP was initiated as a public project funded by government agencies, starting at a moderate pace. The progressive introduction of different actors and the development of various interests catalyzed the project, which eventually became eminent both in the public and private sectors. The competition between the public and the private sector played greatly in favor of both: the financial burden as well as the horizon of the public project were significantly reduced, the private project(s) gained from the hype of the public project, yet had to play an active and collaborative role in order to remain in the game. This is at the core of the social bubble hypothesis. To further our argument, we present quantitative analysis of the development of the biotech sector within the financial stock market. Lastly, we point to the fact that the hypes fueling the bubble during its growth have not been followed by real tangible outcomes over the short expected time horizons. Indeed, at the time of writing (May, 2011), the consensus of the scientific community is that it will take decades to exploit the fruits of the HGP.  相似文献

This paper investigates the effects of trademarks on the market value of firms. The results show that trademarks have a positive effect on firm value. Next, the firms’ market values are regressed on indicators of trademark value such as trademark seniorities, the number of oppositions filed, and the number of product and services classes covered. We found that they at least partially reflect trademark value.  相似文献

ABSTRACT

Issues of maintenance offer exceptional opportunities for advancing our understanding of how market-driven innovation can meet societal objectives for energy transitions. In this article, I present a case study of ongoing attempts by two spin-outs and one start-up to stabilise innovative socio-technical agencements – ‘customer journeys’ – designed to catalyse economic exchange of certain singular goods – energy retrofit products – in the Netherlands. This market-driven innovation relies on sustaining carefully crafted relationships of trust among supply-chain actants and homeowners. I mobilise the analytical lens of ‘care’ to show how the multiplicity of connections that form through socio-technical agencements – and function as a market – are tentative, contested, and unpredictable. Trust relationships are in a constant process of becoming through contestation and convergence among supply-chain actants. In doing so, I expose the precarious and arduous work involved in maintaining a market for singular public goods. This implies a knowledge politics as well: in a call to sensitise us, market scholars, to processes of maintenance integral to market-driven innovation for energy transitions I propose to advance Callon’s call to civilise markets by sharing troubled, though encouraging, care-infused market tales in an effort to counteract the storification of energy transitions as innovation fairy tales.  相似文献

Evaluating the value of athletes to determine whether they should be transferred from one club to another has become a major challenge for managers of sports teams. In the context of German soccer, aficionados have built a large online community that evaluates professional soccer players’ market values. The community has become the main source for reporting market values in the media and has a strong impact on sports economy: it is used in real market transactions and wage negotiations, indicating the power of crowd wisdom in the sports management context.This research describes the evaluation process of the community, investigates the accuracy of its estimated market values, and shows which attributes are most important for market-value evaluations. After demonstrating that the community's market-value estimates can predict actual transfer fees, we show that community evaluations can largely be explained by an econometric model that contains two blocks of determinants: variables that are directly related to players’ talent and variables that result from judgments by external sources (e.g., journalists). Reorganizing variables that were used in previous studies into two blocks (talent vs. external determinants) provides a more differentiated look at the popularity of players than recent literature on the “superstar phenomenon.”  相似文献

针对树木生长建模的复杂性和挑战性,采用分形的方法对树木的生长过程进行建模。根据树木枝干和叶片的自然生长特点,模拟叶片的生长过程,采用分形的算法生成树木的主要枝干,并采用Logistic模型模拟树木的生长过程。通过改变树叶的大小、树的深度、弯曲度以及树的大小等参数实现交互式动态生长模型,能够较为逼真地展现树的生长过程。  相似文献
