Особенности образования неметаллических включений при производстве углеродистой электростали

Изложены результаты, полученных при реализации нового подхода к решению проблемы образования неметаллических включений (НВ), основанного на анализе генезиса и трансформации НВ в стали по всем этапам сталеплавильно–разливочного и прокатного (применительно к условиям сортопрокатно–проволочного стана) переделов

Water Managers' Boundary Judgments and Adaptive Water Governance. An Analysis of the Dutch Haringvliet Sluices Case

__Abstract__ In this paper, we explore how managing actors' boundary judgments influence the adaptability of water governance. We approach this question by examining the relationship between the way water managers frame, and act in, complex water issues on the one hand and develop adaptive water governance strategies on the other. We define four categories of boundary judgments made by water managers in order to deal with the complexities in water governance issues. An in-depth case study analysis of an attempt to adjust the management of the water regime in the south-west Delta of the Netherlands is provided in order to reconstruct the water managers' boundary judgments and their impact upon governance strategies used. We found that, most of the time, the water managers involved predominantly made tight boundary judgments. These tight boundary judgments seemed to hamper the mutual learning process among a variety of stakeholders that is needed to realize adaptive water governance. We argue that wide boundary judgments enhance the chance of realizing adaptive practices and build upon exploration, learning, and connection

Definitiestudie afwegingskader : naar een klimaatbestendig Nederland : definitiestudie Fase 1, kaders voor afweging

Onzekerheid over (omvang en tempo van) de gevolgen van klimaatverandering vormt een essentieel punt bij beslissingen over de ruimtelijke inrichting. De mate waarin en de snelheid waarmee veranderingen optreden zijn niet precies bekend. Een afwegingskader geeft de overheid en de planontwikkelaar instrumenten in handen om de risico’s, de kansen, de kosten en de baten van klimaatadaptatie op verschillende onderscheiden thema’s inzichtelijk te maken. Afwegen: hoe doe je dat. Daarvoor wordt in drie stappen een kader voor gegeven

Evaluating strategic environmental assessment in the Netherlands: Content, process and procedure as indissoluble criteria for effectiveness

To assess the effectiveness of strategic environmental assessment (SEA) we distinguish between its contribution to the quality of the ultimate policy choice (usefulness, applicability), the procedural quality of the planning process (transparency, timeliness) and the quality of stakeholder participation in the planning process (openness, equity, dialogue). In the context of two case studies involving Dutch planning practice, we argue that when and how an SEA is applied is crucial to understanding its e

Trust in governance networks: Its impacts on outcomes

__Abstract__ Governance networks are characterized by complex interaction and decision making, and much uncertainty. Surprisingly, there is very little research on the impact of trust in achieving results in governance networks. This article asks two questions: (a) Does trust influence the outcomes of environmental projects? and (b) Does active network management improve the level of trust in networks? The study is based on a Web-based survey of respondents involved in environmental projects. The results indicate that trust does matter for perceived outcomes and that network management strategies enhance the level of trust

Complexity Theory for a New Managerial Paradigm: A Research Framework

In this work, we supply a theoretical framework of how organizations can embed complexity management and sustainable development into their policies and actions. The proposed framework may lead to a new management paradigm, attempting to link the main concepts of complexity theory, change management, knowledge management, sustainable development, and cybernetics. We highlight how the processes of organizational change have occurred as a result of the move to adapt to the changes in the various global and international business environments and how this transformation has led to the shift toward the present innovation economy. We also point how organizational change needs to deal with sustainability, so that the change may be consistent with present needs, without compromising the future

The interpretations and uses of fitness landscapes in the social sciences

__Abstract__ This working paper precedes our full article entitled “The evolution of Wright’s (1932) adaptive field to contemporary interpretations and uses of fitness landscapes in the social sciences” as published in the journal Biology & Philosophy (http://link.springer.com/article/10.1007/s10539-014-9450-2). The working paper features an extended literature overview of the ways in which fitness landscapes have been interpreted and used in the social sciences, for which there was not enough space in the full article. The article features an in-depth philosophical discussion about the added value of the various ways in which fitness landscapes are used in the social sciences. This discussion is absent in the current working paper. Th

Once the shovel hits the ground : Evaluating the management of complex implementation processes of public-private partnership infrastructure projects with qualitative comparative analysis

Much attention is being paid to the planning of public-private partnership (PPP) infrastructure projects. The subsequent implementation phase – when the contract has been signed and the project ‘starts rolling’ – has received less attention. However, sound agreements and good intentions in project planning can easily fail in project implementation. Implementing PPP infrastructure projects is complex, but what does this complexity entail? How are projects managed, and how do public and private partners cooperate in implementation? What are effective management strategies to achieve satisfactory outcomes? This is the fi rst set of questions addressed in this thesis. Importantly, the complexity of PPP infrastructure development imposes requirements on the evaluation methods that can be applied for studying these questions. Evaluation methods that ignore complexity do not create a realistic understanding of PPP implementation processes, with the consequence that evaluations tell us little about what works and what does not, in which contexts, and why. This hampers learning from evaluations. What are the requirements for a complexity-informed evaluation method? And how does qualitative comparative analysis (QCA) meet these requirements? This is the second set of questions addressed in this thesis
