巷道快速掘进技术是一项系统工程。为了实现矿井高产高效,必须以巷道快速掘进技术为前提和保障。本文以贵州省为例,探讨了巷道快速掘进技术的研究现状及影响因素。针对贵州某矿突出综合检测指标经常超限、掘进速度慢等问题,采用了高压水射流割缝与瓦斯抽放边抽边掘相结合技术。研究表明:该项技术能有效削弱煤层突出危险性,大幅度提高瓦斯抽放量且巷道掘进速度提高了2~3倍。同时根据贵州省的本土情况,提出了针对性地建议和措施,能为巷道快速掘进技术的推广与应用提供一定的指导。  相似文献

In order to build prospective scenarios for biodiesel industry in Brazil, with a sustainable perspective, it was necessary to develop a cross-disciplinary work to include Sachs’ dimensions of sustainability into the scenarios method. This meant linking concepts from different disciplines, without transforming it in a new discipline. In order to support the proposition for the new method, a study case is presented, the framework for the biodiesel scenarios in Brazil, by 2030. An in-depth interview was used to test the proposition of having the sustainability dimensions as driving forces. The result was the identification of a critical uncertainty composed of various aspects related the response to climate change and environmental conservation. The scenario storylines that were developed based on the critical uncertainties showed that sustainable options for the future are possible if the mental maps are enlarged to see beyond the business as usual.The results show that the scenarios storylines go through social, environmental and economic aspects, supported by other aspects like the territorial and political. Also it showed that sustainable options are possible if the mental maps are enlarged to see beyond the business as usual.  相似文献

Stakeholder involvement in research processes is widely seen as essential to enhance the applicability of research. A common conclusion in the extensive body of literature on participatory and transdisciplinary research is the importance of the institutional context for understanding the dynamics and effectiveness of participatory projects. The role of institutional context has become increasingly important in view of large international research projects implementing shared participatory methodologies across countries (for example within Horizon 2020 and within CGIAR programmes), which each have different institutional contexts. Despite the generally accepted importance of the institutional context for understanding the unfolding of participatory and transdisciplinary research projects, surprisingly little research has actually looked into its role in greater detail. This paper aims to fill this gap in the literature by studying how a set of participatory principles and methods in a European project on integrated pest management (denoted as co-innovation in the project under study) was applied by researchers and advisers operating in a single international research project under the institutional conditions of four countries. The principal finding of this study is that, although constraints and enablers of participatory research at the personal level (e.g. researcher identity) were similar across the studied countries, research organisation- and community-based constraints and enablers differed, as well as those at the level of the overall innovation system. The institutions at different levels interact and create country-specific histories and path-dependencies, which lead to different degrees of propensity and preparedness, and hence different starting positions for participatory approaches. Consequently, when participatory research methods and approaches are applied in different contexts following a one-size-fits-all approach they may be less effective if not translated to institutional conditions at different levels. The study suggests that large international participatory research projects make provision in their design for careful selection of project team individuals, the composition of teams, and pay attention to the room for manoeuvre that the project, institute and national contexts provide for participatory research. To support the adjustment of participatory approaches to local institutional conditions, large international projects would benefit from fostering learning spaces that enable reflection on translation to local contexts and are capable of connecting to a wider network of decision makers and influencers that can facilitate institutional change in organisations and innovation systems.  相似文献

This article deals with methodological problems that emerge when trying to construct the necessary information for the reconstruction of the spatial pattern of tourist places on a global scale. A methodology in order to construct a data set on the globalisation of tourism is put forward. It reflects upon the possibility to date the emergence and reproduction of destinations at different moments since 1800. As a solution, we propose to use tourist guidebooks published since 1800 as a source, from which different elements can be extracted.  相似文献

As a method of investigating complex socially relevant phenomena, transdisciplinary research (TDR) is gaining increasing centrality as a model of knowledge production. However, it is being discouraged by a scientific reward system based on disciplinary logic. The disincentive is even stronger for junior scholars who should be developing the capabilities necessary for achieving long-term scientific excellence.Building on theories of the coordination of scientific communities and using the case of a research center of Kyoto University investigating the boundary between cell and material sciences, we aim to disentangle the interplay between institutional incentives and intrinsic motivation in the prioritization of TDR over monodisciplinary research.We find that, despite strong interest in TDR among scientists and the center's mission to promote this orientation, only a minority of scientists prioritize this approach. Choice of research strategy is associated with its perceived benefits for idea generation, publication opportunities, intellectual effort required, the costs of team coordination, and satisfaction with organizational resources. Furthermore, the propensity to prioritize TDR drops among scientists beginning their careers.Therefore, we recommend the development of evaluation schemes grounded in activity-based measures and the granting of permanent positions to scientists pursuing TDR.  相似文献

Denigration of academic experts and expertise, amid a resurgence of political populism, poses a challenge to the legitimacy of academic research. Addressing this challenge requires us to continually demonstrate the importance of basing policy interventions on reliable evidence, rather than unevidenced assertions that gain traction through communication echo chambers. However, unconscious confirmation biases in collection and analysis of evidence can impair the reliability of our research insights. A key source of such confirmation biases are unchallenged ideologies and other taken-for-granted assumptions underlying any research (sub)field. This essay argues that informal and formal peer review processes at many stages of research need to highlight and challenge both conscious selectivity bias and unconscious confirmation bias. However, they are unlikely to do so where researchers only take on board feedback from peers in the same (sub)field who share ideological commitments and taken-for-granted assumptions. In such circumstances, self-referential peer review echo chambers can develop that entrench rather than challenge weaknesses in a research (sub)field. This can be a major risk to the effectiveness and reputation of any academic research (sub)field; a risk we need to confront.  相似文献

We study the characteristics of all published papers in the top three finance journals (JF, JFE and RFS), and how these paper characteristics affect the number of citations in Google Scholar and the Web of Science database. First, we find the characteristics in the universalist perspective remain constant while the characteristics in the constructivist and presentation perspectives increase over time. Second, some characteristics are significantly different between the high-impact and the low-impact papers. Third, paper quality, research method, journal placement and paper age are the most important drivers. Last, different drivers play different roles in different journals.  相似文献

This study has two related goals – one very specific and one more general. The specific goal is to constructively engage with Lodhia (2017) on the issue of whether and to what extent ‘qualitative cousins’ are well served by Faff's (2015) original pitching research (PR) template. Using this ‘cousins’ focus as a primer, the more general goal is to update the agenda created by Faff (2015) and in so doing, explore the ‘extended family’ of PR work/resources now available.  相似文献
