Construction projects' duration can be modelled using traditional and artificial intelligence methods. The first part of these two papers provides an insight into the principles of modelling project durations using neurofuzzy methods. This paper presents an understanding of how these methods operate and discusses the main issues concerning their use and application in construction management. An introduction to the problems of modelling and predicting construction projects' duration is first presented. This is followed by explaining the neurofuzzy life cycle modelling process and discussing methods for modelling projects' duration. A graphical presentation of the way in which neurofuzzy methods operate is also presented and discussed.

While memory institutions' use of social media has proliferated, research and scholarly literature on risks, resulting from social media use, memory institutions' social media risk-aware culture and, in particular, social media risk management remains scant. This study addresses this knowledge gap and identifies aspects of social media risk management from other sectors that could inform the cultural heritage sector.

This research involves a review of the scholarly and professional literature that contribute to social media risk management discourses. These include those that discuss the different categories of social media risks, social media policies, risk-aware culture and social media risk management strategies and processes. Works discussing social media risk management models and frameworks are also included in the review. Based on the insights gained from these reviews, a pillar framework to guide social media risk management in memory institutions is developed.

The proposed framework outlines the baseline components relevant for the cultural heritage sector and underlines the evolving and continual nature of these components. Elements particularly important to memory institutions are highlighted. Notably, that social risks as a risk category must be recognised. Also noted is that the conventional apolitical stance still taken by many memory institutions need to be reviewed. The importance of memory institutions to be not overly risk-averse to the point of failing to take advantage of the affordances of social media platforms, thereby stifling potential innovations around services and engagement with their users/audience is discussed.

This research offers an extensive review of the social media risk management literature, both scholarly and professional across different domains. The ensuing insights inform the development of a pillar framework to guide social media risk management in memory institutions. The framework outlines a baseline mapping of the governance, processes and systems components. The expectation is that this framework could be extended to account for contextual and situational requirements at more granular levels to reflect the nuances, variances and complexities that exist among different types of memory institutions and to account for varying attributes, mandates and priorities in the cultural heritage sector.

The purpose of this paper is to show that relationships between academics and professionals can gain in organizational studies by prioritizing practical wisdom, which also benefits teaching.

To explore practical corollaries of Flyvbjerg's claim that social scientists are better equipped than natural scientists to produce phronesis or practical wisdom.

Practical wisdom emerges when social scientists interact with professionals. In (relational) practice, Organizational Science scientists and practitioners develop local knowledge that cannot be taught a priori but which develops bottom up and emerges from practice. Scientists and practitioners converse, exchange interpretations and perspectives, in specific contexts. Interaction and communication with OS practitioners seems for OS professionals to be a necessary human condition to develop phronesis.

Explores implications of Flyvberg's method to critically study discourse among OS scientists and between them and OS practitioners. Examine how discourse changes on the basis of an example of phronesis.

To provide a practical contribution to the theory/practice debate.

Coproduction is both a recurrent way of organizing public services and a maturing academic field. The academic debate has analyzed several facets, but one deserves further analysis: its impact on the cost efficiency of public services. The purpose of this paper is to aim at systematizing the findings on the relationship between coproduction and cost efficiency and at developing insights for future research.

This paper is based on a structured literature review (SLR), following the approach proposed by Massaro, Dumay and Guthrie. The SLR approach differs from traditional narrative reviews since, like other meta-analysis methods, it adopts a replicable and transparent process. At the same time, when compared to most common meta-analysis or systematic review logics, it is better suited to incorporate evidence from case studies and etnographies. This makes the method especially suited to public administration and management studies.

Results shed light on the nature of the academic literature relating coproduction to cost efficiency, on what type of costs are affected and how and on the meaningfulness of productivity measures when public services are co-produced.

In times of fiscal distress for many governments, the paper contributes to research and practice in systematically re-assessing the effects of coproduction on public budgets.
