    Producing a bill of quantity is a knowledge-based, dynamic and collaborative process, and evolves with variances and current evidence. However, within the context of information system practice in BIM, knowledge of cost estimation has not been represented, nor has it been integrated into the processes based on BIM. This paper intends to establish an innovative means of taking data from the BIM linked to a project, and using it to create the necessary items for a bill of quantity that will enable cost estimation to be undertaken for the project. Our framework is founded upon the belief that three components are necessary to gain a full awareness of the domain which is being computerised; the information type which is to be assessed for compatibility (syntax), the definition for the pricing domain (semantics), and the precise implementation environment for the standards being taken into account (pragmatics). In order to achieve this, a prototype is created that allows a cost item for the bill of quantity to be spontaneously generated, by means of the semantic web ontology and a forward chain algorithm. Within this paper, ‘cost items’ signify the elements included in a bill of quantity, including details of their description, quantity and price. As a means of authenticating the process being developed, the authors of this work effectively implemented it in the production of cost items. In addition, the items created were contrasted with those produced by specialists. For this reason, this innovative framework introduces the possibility of a new means of applying semantic web ontology and forward chain algorithm to construction professional practice resulting in automatic cost estimation. These key outcomes demonstrate that, decoupling the professional practice into three key components of syntax, semantics and pragmatics can provide tangible benefits to domain use

    Relation between organizational commitment and professional commitment: an exploratory study conducted with teachers

    The existence of several kinds of commitments in the workplace is well known. However, there are few studies that relate these different commitments or those established by deterministic models. This study explored the relationship between organizational and professional commitment in public higher education professors according to the multidimensional perspective of Meyer and Allen (1991), based on a convenience sample of 219 teachers. The proposed models were estimated through structural equation modeling methodology. Model 1 specified a relationship of direct influence of Professional Commitment on Organizational Commitment and Model 2 established the opposite relationship of direct influence of organizational commitment on professional commitment. Both models presented a good fit to the data without statistically significant differences between them. Nevertheless, the explanatory power of Model 1 was superior to Model 2, due to the fact that it includes a larger number of determinant relationships that are statistically significant. Theoretical and practical implications were discussed and new directions for future research were identified.info:eu-repo/semantics/publishedVersio

    Organisational Legitimacy, Capacity and Capacity Development

    The European Centre for Development Policy Management (ECDPM) has undertaken a study of capacity development, with a focus on organisational change and performance enhancement. Both individual organisations and networks of organisations have been studied with the aim of identifying important relationships among endogenous change factors (e.g. ownership, commitment and managerial style), key internal organisation variables (e.g. structures, procedures, staffing and management systems), performance and sustainability outcomes, and external environmental factors (e.g. policy frameworks, resource availability, politics, stakeholders, governance regimes, etc.).To date, the ECDPM study team has conducted 16 case studies (see Appendix). Among the findings that have emerged from several of the cases is the presence of an organisation's legitimacy as a factor contributing to successful capacity and performance. To delve in more detail into the concept of legitimacy, and to identify the implications for capacity building, ECDPM commissioned a working paper on the topic. This exploratory paper reviews the relevant literature and examines: differing definitions, types and sources of legitimacy; the links between legitimacy and organisational capacity, performance and sustainability; and management strategies for building and maintaining legitimacy. It discusses a selected set of the ECDPM cases in terms of the legitimacy concept

    Effectiveness is the gold standard of clinical research

    Psychological treatments have been shown to be at least as effective (and sometime even more effective) than psychotropic medications for many psychiatric disorders, in particular anxiety disorders, depressive disorders, and personality disorders (American Psychological Association, 2013; Cuijpers, 2017). Effective psychological treatments are also cost-effective: their implementation in public mental health services is convenient in financial terms, with decades of studies consistently demonstrating a reduction in public spending for psychological health (Abbass, Kisely, Rasic, Town & Johansson, 2015). Therefore, it could be critical that psychological treatments whose efficacy is supported by strong empirical evidence can be delivered as a primary choice in public mental health services. We hope and believe that the time when a psychologist or a psychiatrist (especially if paid by the public mental health system) could provide any treatment he or she thought fit, even in the absence of any scientific evidence of its efficacy, is coming to an end. However, a recommendation should be made to be very careful in not equating the empirical support of a given treatment with the sole presence of randomized controlled trials (RCTs) that show its efficacy. This would be a mistake from both an empirical and a theoretical perspective, as it runs the risk of throwing out the baby with the bathwater. In other words, endorsing a perspective according to which a specific treatment should be promoted or rejected on the sole basis of findings from RCT studies runs the risk of putting clinical science back almost twenty years from the current more advanced understanding of the efficacy, effectiveness, and usefulness of psychotherapy (Dazzi, 2006; Dazzi, Lingiardi, & Colli, 2006; Leichsenring et al., 2016; Silberschatz, 2017)

    Explaining the effects of an intervention designed to promote evidence-based diabetes care : a theory-based process evaluation of a pragmatic cluster randomised controlled trial

    Background The results of randomised controlled trials can be usefully illuminated by studies of the processes by which they achieve their effects. The Theory of Planned Behaviour (TPB) offers a framework for conducting such studies. This study used TPB to explore the observed effects in a pragmatic cluster randomised controlled trial of a structured recall and prompting intervention to increase evidence-based diabetes care that was conducted in three Primary Care Trusts in England. Methods All general practitioners and nurses in practices involved in the trial were sent a postal questionnaire at the end of the intervention period, based on the TPB (predictor variables: attitude; subjective norm; perceived behavioural control, or PBC). It focussed on three clinical behaviours recommended in diabetes care: measuring blood pressure; inspecting feet; and prescribing statins. Multivariate analyses of variance and multiple regression analyses were used to explore changes in cognitions and thereby better understand trial effects. Results Fifty-nine general medical practitioners and 53 practice nurses (intervention: n = 55, 41.98% of trial participants; control: n = 57, 38.26% of trial participants) completed the questionnaire. There were no differences between groups in mean scores for attitudes, subjective norms, PBC or intentions. Control group clinicians had 'normatively-driven' intentions (i.e., related to subjective norm scores), whereas intervention group clinicians had 'attitudinally-driven' intentions (i.e., related to attitude scores) for foot inspection and statin prescription. After controlling for effects of the three predictor variables, this group difference was significant for foot inspection behaviour (trial group × attitude interaction, beta = 0.72, p < 0.05; trial group × subjective norm interaction, beta = -0.65, p < 0.05). Conclusion Attitudinally-driven intentions are proposed to be more consistently translated into action than normatively-driven intentions. This proposition was supported by the findings, thus offering an interpretation of the trial effects. This analytic approach demonstrates the potential of the TPB to explain trial effects in terms of different relationships between variables rather than differences in mean scores. This study illustrates the use of theory-based process evaluation to uncover processes underlying change in implementation trials.European Union ReBEQI projec
