An infrastructure impact assessment process relies on the analysis of multiple types of models, the performance of individual infrastructure networks and the interdependencies between multiple infrastructure networks. Several models are developed for their specific purposes and there is a need to link these models for the assessment of natural hazard impacts on distributed infrastructures to deliver the desired outcomes on network functionality and disruption levels that are suitable to assess socio-economic impact. In this paper, an ‘end-to-end’ linkage structure is proposed to link different models by which various features, data standards, parameters and structures are linked in a transparent and consistent manner. The framework has adopted a dedicated knowledge discovery and data analysis process to acquire information around input and output parameters for each of these models developed by various researchers and used in risk assessment tools. The framework is illustrated by applying the step-by-step procedure towards integrated impact assessments of electricity, potable water and road networks and their interdependencies.

AbstractImpact assessment is a widely used and cost-effective tool for prioritising invasive alien species. With the number of alien and invasive alien species expected to increase, reliance on impact assessment tools for the identification of species that pose the greatest threats will continue to grow. Given the importance of such assessments for management and resource allocation, it is critical to understand the uncertainty involved and what effect this may have on the outcome. Using an uncertainty typology and insects as a model taxon, we identified and classified the sources and types of uncertainty when performing impact assessments on alien species. We assessed 100 alien insect species across two rounds of assessments with each species independently assessed by two assessors. Agreement between assessors was relatively low for all three EICAT components (mechanism, severity, confidence) after the first round. For the second round, we revised guidelines and gave assessors access to each other’s assessments which improved agreement by between 20-30%. Of the 12 potential reasons for assessment discrepancies identified a priori, 11 occurred. The most frequent sources (and types) of uncertainty (i.e. differences between assessment outcomes for the same species) were: incomplete information searches (systematic error), unclear mechanism and/or extent of impact (subjective judgment due to a lack of knowledge), and limitations of the assessment framework (context dependence). In response to these findings, we identify actions to reduce uncertainty in the impact assessment process, particularly for assessing speciose taxa with diverse life histories such as Insecta. Evidence of environmental impact was available for most insect species, and (of the non-random original subset of species assessed) 14 or 29% of those with evidence were identified as high impact species (with either ‘Major’ or ‘Massive’ impact). Although uncertainty in risk assessment, including impact assessments, can never be eliminated, identifying and communicating its source and variety is a first step toward its reduction and a more reliable assessment outcome, regardless of the taxa being assessed.

Objective To examine the causes of variation for determining clinical eligibility for a national caregiver programme in the US Veterans Health Administration (VHA) and so help inform standardization of clinical eligibility assessment for support and establish conditions for more consistent caregiver experiences across the country. Methods We used mixed methods, including a national survey of caregiver support coordinators (CSCs) across VHA medical centres, semi-structured interviews with a purposive sample of 53 CSCs and interdisciplinary team members, and observations of four VHA medical centre sites. Results A majority (70%) of CSCs across VHA medical centres reported that they used interdisciplinary teams to conduct assessments. Interdisciplinary teams were seen to help mitigate potential harm to therapeutic relationships from eligibility decisions. Survey respondents reported using a range of assessment tools provided by the national VHA Caregiver Support Program office, but participants expressed concerns that the tools did not necessarily effectively assess clinical need. Some local sites had developed innovative person-centered approaches, in which the assessment process provided an opportunity to assess veterans’ holistic clinical needs, in contrast to a programme-centered approach, which focused on assessing whether veterans/their caregivers meet eligibility criteria. Conclusion Discretion by those involved in making decisions on programme eligiblity is important for implementing a national social services programme based on clinical need. Interdisciplinary teams can help mitigate potential harm to therapeutic relationships. Discretion allows for innovation. This work has implications for setting policy in other programme contexts in which applying eligibility criteria requires clinical judgment.

The high energy demand and the threat of climate change have led to a remarkable development of renewable energies, initially through technologies applied to the terrestrial environment and, recently, through the awakening of marine renewable energies. However, the development of these types of projects is often hampered by failure to pass the corresponding environmental impact assessment process. The complexity of working in the marine environment and the uncertainties associated with assessing the impacts of such projects make it difficult to carry out objective and precise environmental impact assessments. AMBEMAR-DSS seeks to establish a basis for understanding and agreement between the different stakeholders (project developers, public administrations, environmental organizations and the public in general), in order to find solutions that allow the development of marine renewable energies, minimizing their environmental cost. For this purpose, a DSS is proposed which, based on cartographic information and using objective and quantifiable criteria, allows comparative assessments and analyses between different project alternatives. The analytical procedures used by the system include, among others, hydrodynamic modeling tools and visual impact simulators. In addition, impacts on marine species are assessed taking into account intrinsic ecological and biological aspects. The magnitude of the impacts is quantified by means of fuzzy logic operations and the integration of all the elements is carried out by an interactive multi-criteria analysis. The results are shown in tables, graphs and figures of easy interpretation and can be also visualized geographically by means of a cartographic viewer. The system identifies the main impacts generated in the different phases of the project and allows establishing adequate mitigation measures in search of optimized solutions. The establishment of the assessment criteria has been based on the abundant, but dispersed, scientific literature on the various elements of the system and having the opinion of experts in the various fields. Nevertheless, the DSS developed constitutes a preliminary basis on which to build and improve a system with the input of researchers, promoters and experts from different disciplines.

Purpose Though we live in a digital era, libraries offer significant hours of in-person reference services, in combination with online reference services. Nevertheless, an increase in requests for in-person, individualized research consultations (IRCs) over the last few years has been observed. IRCs between librarians and students are common practice in academic institutions. While these sessions can be deemed useful for patrons, as they are tailored to their specific needs, however, they can also be time consuming for the librarians. Therefore, it is important to evaluate this service, and assess its impact in order to ensure that the users are getting the most out of their sessions. The purpose of this paper is to gather information on the evaluation and assessment tools that Canadian institutions are using to obtain feedback, measure their impact and improve their consultation services. Design/methodology/approach A bilingual (French and English) web-based questionnaire was issued, with a generic definition of IRCs provided. The questionnaire included general demographics and background information on IRC practices among Canadian academic librarians, followed by reflective questions on the assessment process of such practices. The questionnaire was sent to Canadian academic librarians via e-mail, using professional librarian associations’ listservs, and Twitter was used for dissemination as well. Findings Major findings of the survey concluded that the disciplines of health sciences and medicine, as well as the arts and humanities are the heaviest users of the IRC service model. On average, these sessions are one hour in length, provided by librarians who often require advanced preparation time to adequately help the user, with infrequent follow-up appointments. It was not surprising that a lack of assessment methods for IRCs was identified among Canadian academic libraries. Most libraries have either no assessment in place for IRCs, or they rely heavily on informal feedback from users, comments from faculty members and so on. A small portion of libraries use usage statistics to assess their IRCs service, but other means of assessment are practically non-existent. Research limitations/implications The survey conducted was only distributed to Canadian academic libraries. Institutions across the USA and other countries that also perform IRCs may have methods for evaluating and assessing these sessions which the authors did not gather; therefore, the evidence is biased. As well, each discipline approaches IRCs very differently; therefore, it is challenging to compare the evaluation and assessment methods between each discipline. Furthermore, the study’s population is unknown, as the authors did not know the exact number of librarians or library staff providing IRCs by appointment in academic Canadian institution. While the response rate was reasonably good, it is impossible to know if the sample is representative of the population. Also, it needs to be acknowledged that the study is exploratory in nature as this is the first study solely dedicated at examining academic librarians’ IRC practices. Further research is needed. As future research is needed to evaluate and assess IRCs with an evidence-based approach, the authors will be conducting a pre-test and post-test to assess the impact of IRC on students’ search techniques. Originality/value Evidence-based practice for IRCs is limited. Very few studies have been conducted examining the evaluation and assessment methods of these sessions; therefore, it was believed that a “lay of the land,” so to speak, was needed. The study is exploratory in nature, as this is the first study solely dedicated at examining the evaluation and assessment methods of academic librarians’ IRC practices.
