Abstract Infrastructure-induced fragmentation of riverine ecosystems has prompted the need for more effective aquatic restoration efforts globally. Fragmentation assessments have been extensively undertaken to inform connectivity restoration efforts for fish and other aquatic biota, but they have potentially underestimated the extent of fragmentation by fixating on large dams and overlooking the contribution of other barriers like road crossings and small irrigation structures. The current study addresses this limitation in Mekong region countries (MReCs) of Southeast Asia, by assessing the fragmentation impacts of road crossings and small irrigation structures together with large dams. Our analysis indicates that the basin-scale fragmentation impact of road crossings is similar to that of large dams in MReCs, while small irrigation structures have a far greater impact. These findings raise concerns about the real global extent of aquatic fragmentation, and highlight the need for decision-makers to think beyond dams when attempting to restore connectivity for aquatic biota.

The paper presents a discussion on fuzzy rationality in the elicitation of subjective probabilities and utilities. In addition to previous research, two functions, measuring the degree of preference of the real decision maker on both sides of the uncertainty interval are introduced, and their relationship with the indifference function, measuring the degree of indifference of the decision maker over gambles, is analyzed and graphically interpreted. A new relation -- hesitation -- is introduced to give a better description of the actual process of subjective elicitation by real decision makers. The influence of the preference-hesitation combination in an elicitation process is presented graphically, and it is argued that the resulting uncertainty interval is much tighter than the one, resulting from the preference-indifference based elicitation.

Purpose The purpose of this paper is to examine how the real estate owner (decision maker) insures being able to make informed decisions and how they differ according to organisational form. Design/methodology/approach This research is based on an interview study of nineteen firm representatives, six decision makers and thirteen management representatives, all from Swedish commercial real estate sector. Findings The study concludes that, regardless of organisational setting, the industry has a plan regarding handling information. The decision makers have all secured themselves access to the required/desired information. How this is done and what kind of information it is however differ, if the real estate management is in-house or outsourced. Furthermore, a clear focus on financial and contractual information is evident in both organisational settings. Research limitations/implications The research in this paper is limited to Swedish commercial real estate sector. Practical implications The insight the paper provides regarding required information can shed light on how information systems are built and how to improve your information sharing. Originality/value It provides an insight regarding how the industry, depending on organisation setting, prioritises different information and how the decision maker secures access to it.

Every industry keen to maximize their company profit by fulfils the customer’s satisfaction by perform a very good project deliverable. However, very limited researches on uncertainty in environmental issues (EI) probably could turn as a biggest problem for company, especially in late delivery of project completion for construction industry (CI). Uncertainty factors could be mapped by many causes and affects which known or unknown, statically to totally ignorance. Previously, most of research on uncertainty have been model their factors of uncertainties but pay no attention to the EI, whereas in the real cases all the factors must controlled and manageable even it is in-deterministic or non-realistic. Therefore, the modelling of uncertainty factors in EI on late delivery for CI is very important to studied, and it will be considered to be used as the guidance for decision makers when they are facing of the problems that related to uncertainties. This paper will purpose the conceptual model on progress to the modelling of uncertainty factors in EI on late delivery for CI. The uncertainty of environmental can split into two categories; acts of God and acts of humans.

Abstract. Warning is a key issue to reduce flash floods impacts. But, despite many studies, local and national authorities still struggle to issue good flash floods warnings. We will argue that this failure results from a classical approach of warnings, based on a strict separation between the assessment world and the action world. We will go further than the previous criticisms (Pielke and Carbone, 2002) and show that forecasters, decision makers, emergency services and local population have quite similar practices during a flash-flood warning. Focusing on the use of meteorological information in the warning process, our case study shows that more research about the real practices of stakeholders would be another step towards integrated studies.

BACKGROUND Application of artificial intelligence (AI) in healthcare is accelerating but relatively little is yet known about the real-world implementation of AI in clinical workflows. OBJECTIVE In this paper, we have focused on one application of AI as a second reader of breast mammograms in the context of a national breast screening programme. We look at the development and testing of an AI image reading tool for mammograms and the effect of organisational readiness for AI tool adoption. We focus on two aspects of organisational readiness as conceptualised by Weiner (2009) for AI technology specifically and answer the questions (1) what are the views of the technology adopters in a healthcare organisation to the use of AI technology in the case of breast screening? (2) What are some of the emerging organisation factors that are likely to effect adoption and spread and are any unique to AI technology? METHODS A prospective mixed methods study of the real-world development of AI tools for use in the National Breast Screening Programme in England. We recruited 67 radiologists and reporting radiographers in four breast screening services and 18 organisational leaders who were the AI project decision-makers. Data was collected using an online survey of breast screening staff (adopters), semi-structured interviews with organisational leaders, participant observation of project meetings and document review. Data regarding organisational and adopter readiness for technology adoption was analysed over the duration of the project. RESULTS Sixty-seven clinicians and eighteen organisational leaders participated the study. Commitment to adoption is positive but adopters want to see clinical evidence of AI safety and accuracy. Decision-makers and other organisational adopters do not yet have shared views on their resources, capacity and capability to adopt and spread the technology and significant challenges related to task demands and situational factors emerged during the project causing substantial delays to adoption. The nature of AI and ML technology surfaced novel complexities not encountered by traditional health technology related to explainability and meaningful decision-support. CONCLUSIONS The case study shows that adopter commitment in this case and AI technology in breast screening is growing but gaps remain in the collective capability of organisations to adopt these novel technologies.

Developing countries in Asia are in the process of transitioning from a production economy to a knowledge-based economy. Various new knowledge and information communications technology mega-projects are being designed and executed at the international, national, state and industry levels to sustain competitiveness. The structures and processes by which these so-called “knowledge super corridors” are developed and implemented are complex economic-social-political decisions. The author develops an enhanced framework from critical theory, whereby the critical practice lens provides an iterative reflexive process, firstly by developing knowledge for understanding from structuration theory. Secondly, the author provides a critique of underpinning assumptions and presumptions whereby the constraining conditions of the status quo and emancipation become knowable and explicit, that is, knowledge for evaluation. Thirdly, the knowledge for action generated will enable the decision makers to re-create, re-define, re-design, re-imagine, re-invent and re-vision pragmatic, doable and implementable programs to transform a developing country into a k-economy. The author illustrates the value of the enhanced model using two case studies concerned with formulating and implementing a k-economy blueprint and developing a knowledge portal in emerging k-economies in Southeast Asia.
