Be vicarious: the challenge for project management in the service economy
Purpose. The paper aims to answer to the following questions: which are the critical dynamic capabilities to survive in the rubber landscape of service economy? Does it exist in service economy a dynamic capabilities provider?
Methodology. The paper combines the literature review on dynamic capability perspective and that on vicariance to the Project Management professional services. Findings. Firstly, the paper identifies vicariance as an intriguing dynamic capability, crucial to survive in the rubber landscape of service economy. Secondly, the paper sheds light on Project Management (PM) as a vicarious that provides vicariance.
Practical implications. For each critical organizational dimension, the paper identifies the links among the service economy challenges and the vicariance typology required to the project manager to face those challenge.
Originality/value.The approach to conceive the PM as a vicarious that provides vicariance is original and leads to new insights on the professional services management. In fact, on one hand, dynamic capabilities cannot easily be bought through a market transaction; on the other hand, they must be built. This building can be achieved internally, by the organization itself (i.e. hierarchy), or through a partnership (i.e. hybrid form among hierarchy and market). PM professional services enrich organizations with additional information variety according to a hybrid (i.e. non- market) coordination model
The PMBOK standard evolution: leading the rising complexity
The aim of this work is to enlighten how the Standard for Project Management (part II of PMBOK® Guide) has evolved over the last 30 years as it has introjected the perspective of complexity. The several contexts (private firms, public institutions etc.) in which Project Management is applied become more and more complex (i.e. uncertain and characterized by unpredictable feedbacks among their own variables and their environments). This needs an enrichment (and perhaps a new conceptualization) of the endowment of information variety provided by the Standard for Project Management with respect to the specific requisite variety asked at a local level (i.e. the specific organizational contexts), to lead a project with efficiency, effectiveness and sustainability.
The traditional Standard for Project Management can no longer be considered as a “comfort zone” (i.e. a set of established and “familiar” frameworks, rules and tools aiming to ensure certain and predictable results). On the contrary, the Standard for Project Management should shift towards an open standard, that is able to consistently co-evolve with the increasingly complex contexts that even more ask for new tools, creative solutions and original combinations between exploitative and explorative knowledge
Matter-wave interferometry: towards antimatter interferometers
Starting from an elementary model and refining it to take into account more
realistic effects, we discuss the limitations and advantages of matter-wave
interferometry in different configurations. We focus on the possibility to
apply this approach to scenarios involving antimatter, such as positrons and
positronium atoms. In particular, we investigate the Talbot-Lau interferometer
with material gratings and discuss in details the results in view of the
possible experimental verification.Comment: 18 pages; 8 figure
Compressive Sensing for Dynamic XRF Scanning
X-Ray Fluorescence (XRF) scanning is a widespread technique of high
importance and impact since it provides chemical composition maps crucial for
several scientific investigations. There are continuous requirements for
larger, faster and highly resolved acquisitions in order to study complex
structures. Among the scientific applications that benefit from it, some of
them, such as wide scale brain imaging, are prohibitively difficult due to time
constraints. However, typically the overall XRF imaging performance is
improving through technological progress on XRF detectors and X-ray sources.
This paper suggests an additional approach where XRF scanning is performed in a
sparse way by skipping specific points or by varying dynamically acquisition
time or other scan settings in a conditional manner. This paves the way for
Compressive Sensing in XRF scans where data are acquired in a reduced manner
allowing for challenging experiments, currently not feasible with the
traditional scanning strategies. A series of different compressive sensing
strategies for dynamic scans are presented here. A proof of principle
experiment was performed at the TwinMic beamline of Elettra synchrotron. The
outcome demonstrates the potential of Compressive Sensing for dynamic scans,
suggesting its use in challenging scientific experiments while proposing a
technical solution for beamline acquisition software.Comment: 16 pages, 7 figures, 1 tabl
Stepwise Hierarchical Self-Assembly of Supramolecular Amphiphiles into Higher-Order Three-Dimensional Nanostructures
Smart Biomechanical Adaptation Revealed by the Structure of Ostrich Limb Bones
Ostriches are known to be the fastest bipedal animal alive; to accomplish such an achievement, their anatomy evolved to sustain the stresses imposed by running at such velocities. Ostriches represent an excellent case study due to the fact that their locomotor kinematics have been extensively studied for their running capabilities. The shape and structure of ostrich bones are also known to be optimized to sustain the stresses imposed by the body mass and accelerations to which the bones are subjected during movements. This study focuses on the limb bones, investigating the structure of the bones as well as the material properties, and how both the structure and material evolved to maximise the performance while minimising the stresses applied to the bones themselves. The femoral shaft is hollowed and it presents an imbricate structure of fused bone ridges connected to the walls of the marrow cavity, while the tibial shaft is subdivided into regions having different mechanical characteristics. These adaptations indicate the optimization of both the structure and the material to bear the stresses. The regionalization of the material highlighted by the mechanical tests represents the capability of the bone to adapt to external stimuli during the life of an individual, optimizing not only the structure of the bone but the material itself
Wavefront and nanostructure characterisation with X-ray ptychography
X-ray ptychography is a scanning diffraction microscopy technique suited for the phase-sensitive investigation of wavefronts and specimens. It returns complex-valued wave functions and transmission functions producing high-resolution (nanoscale) phase- contrast images. This work focuses on the implementation and application of X-ray ptychography in the context of synchrotron radiation facilities. It presents an experimental protocol developed for multiscale X-ray imaging and tested at the I13-1 Coherence Branchline at Diamond Light Source. This protocol combines both near-field and far-field ptychography with other imaging methods, providing a flexible way of conducting experiments on hierarchical structures at any high-brilliance X-ray facility. This work also reports ptychography experiments performed at free-electron lasers, aimed at characterising their pulsed beam. Both the average and individual wavefronts are retrieved through a novel application of a reconstruction algorithm based on singular- value decomposition, giving direct insight on pulse-to-pulse fluctuations and confirming ptychography as a powerful beam diagnostics technique. Additional ptychography experiments are also discussed, which were carried out at storage rings on flat, weakly-scattering biogenic samples to characterise their 3D nanos- tructures. Their data analysis pipeline is presented in detail, from data acquisition to rendered volumes. Furthermore, one of these last experiments constitutes the first successful 3D ptychography experiment run on real-life samples at the I13-1 Coherence Branchline at Diamond Light Source
Motivations of non-use of telecentres: a qualitative study from Mozambique
On the cutting-edge scene for several years, and recently overtaken by the diffusion of more personal and pervasive technologies, telecentres have attracted and are still luring the interests of Governments in developing regions. To individuate improvement strategies and give food for thoughts to researchers and practitioners in the area, this study presents an in-depth qualitative analysis of the reasons why local people in Mozambique do not access the telecentre component of their local Community Multimedia Centers (CMCs). Based on 229 semi-structured interviews, the analysis allows to depict four main clusters of reasons for non-use, to finally suggest how they can be overcome
Firm, territory and local community: lessons learned from the Olivetti’s model
The paper discusses the relevance of the Olivetti model and the validity of that entrepreneurial experience based on values such as the concrete community, the territory and urban planning, and a source of virtuous learning to face the tensions of the current socio-economic systems. Through the methodology of the case study, the one developed by Adriano Olivetti is qualified as an arbor vitae business model: a model based on ethics and community, a culture of innovation and aesthetics in design. Thus, the Olivettian model of the arbor vitae is assumed as an ideal-typical model. It can assess the virtuosity or otherwise the possible corporate behavior in the current socio-economic contexts. The article ends by emphasizing the vast cultural heritage left by Olivetti to the city of Ivrea, the company’s headquarters. The Ivrea Olivetti factory became a virtuous model of work organization. It has made Ivrea as a smart land ante litteram conceived for man and not exclusively for the often dehumanizing efficiency of the assembly line. Olivetti factory in Ivrea became a model of a work organisation while the Ivrea community a smart land designed on the person and not on the dehumanized work of the assembly line: all these reasons have led Ivrea – the Industrial City of the 20th Century – to be recognized as the 54th Italian UNESCO Heritage. Il lavoro discute l’attualità del modello olivettiano e la validità di quell’esperienza imprenditoriale basata su valori quali la comunità concreta, il territorio e la pianificazione urbana e fonte di apprendimento virtuoso per affrontare le tensioni degli attuali sistemi socio-economici. Adottando la metodologia del caso di studio, quello sviluppato da Adriano Olivetti viene qualificato come modello di impresa arbor vitae: un modello fondato su etica e comunità , cultura dell’innovazione e dell’estetica nel design. Il modello olivettiano dell’arbor vitae viene così assunto a modello idealtipico sulla cui base valutare la virtuosità o meno dei possibili comportamenti d’impresa negli attuali contesti socio-economici. Il saggio si chiude sottolineando l’ingente eredità culturale lasciata da Olivetti alla città di Ivrea, sede dell’azienda. La fabbrica olivettiana di Ivrea divenne un modello virtuoso di organizzazione del lavoro e fece di Ivrea una smart land ante litteram concepita per l’uomo e non esclusivamente per l’efficienza, spesso disumanizzante, della linea di assemblaggio: proprio questa profondamente umana quanto illuminata concezione dello spazio lavorativo quale spazio innanzitutto di rapporto interumano è valsa ad Ivrea – Industrial City of the 20th Century – il prestigioso riconoscimento di 54° sito UNESCO italiano
