This paper proposes a simple approach to critical path analysis in a project network with activity times being intervals and which are converted into various Type-2 fuzzy quantities. The idea is based on generalized type-2 trapezoidal, hexagonal and octagonal fuzzy numbers and its ranking. The explicit form of membership functions of the type-2 fuzzy activity times is not required in the proposed approach. Moreover, the method is very simple and the numerical example is given for demonstrating and comparing the proposed approach with generalized type-2 trapezoidal, hexagonal and octagonal fuzzy numbers through proposed ranking function.

In this paper, the authors propose a new method to compute the fuzzy latest times and float times of activities for a project scheduling problem with fuzzy activity times. The authors have considered LR fuzzy numbers to represent the activity times. As the data of the problem are LR fuzzy numbers, the authors have shown that the results are also in terms of LR fuzzy numbers. Total float time of each activity can be found by this method without using the forward pass and backward pass computations. The authors use an example to illustrate the method. This paper shows the advantages of this method over the existing methods with great clarity. The proposed method illustrates its application to fuzzy critical path problems occurring in real life situations.

Valérie par Valérie opens new critical paths which are fertile, though difficult to unpack. Published under the enigmatic and collective name La Rédaction, this book – whose main (or only) author seems to be Christophe Hanna – develops what we could call a viral critique, which seeks to occupy dominant ideologies to undermine them from within rather than oppose them with a new ideology. This article aims firstly to define Hanna's viral critique, based on his own theoretical works and Guy Debord's notion of spectacle as a social and economic mechanism. It then analyzes the specific form taken by that critique in Valérie par Valérie, where the author opposes the separation of literary and non-literary forms, as well as contemporary ultracapitalism and its political-economic ramifications. Finally, the ethical implications of this type of implicit critical exercise are explored through semioethics, in order to determine the efficiency of Hanna's project.

Abstract In this paper, we highlight the networked context of the professions. In particular, we indicate that neo-classical professionals tend to work across organizational boundaries in project teams, often to meet the needs of clients and the wider society. However, little is known about the resources that professionals draw on to meet immediate, fast paced, client demands in project network organizations (PNOs). We pinpoint how knowledge resources, human, social and organizational capital enable professionals to produce outputs at a fast pace/tempo. Temporality emerged as an unexpected but key issue in our empirical research and we explore this further here. First, we put forward how professional work organization(s) has changed by focusing on the boundaries of organizations, and how this is often temporary and project-driven. Second, we use the specific lens of knowledge resources which are drawn upon to enable networked working and ask the question: which knowledge resources enable professionals to work at a fast pace within networks? Third, appreciative of the vast literature on temporary and networked organizations in professional work, our focus is beyond a single profession or organization, and hence, we build upon the prior research on PNOs. We do this by drawing on empirical data of a humanitarian aid project networked organization (HN) that upscales across its network at high speed, often within days, to generate funds for humanitarian disasters in order to save lives.
