Place as Value proposition. The Marketing Perspective
No full textThis work provides a particular perspective on the polysemous concept of ‘place’ and integrates marketing and management frameworks - S-D Logic, Service Science and Network-System theories - to explain the place as value
proposition, emergent by the perceptions and interactions between subjects/stakeholders/users and the spatial contexts.
A service perspective emerges and the value co-creation logic is applied to place marketing, identifying an alternative vision in managing value and strategies in places. This marketing approach is contextualized to the city centre, and presents the value co-creation perspective within the Town Centre Management (TCM) scheme. Implications between marketing, management, government and stakeholders are identified in place dynamics
Metacity: città, Informatica e società. Impatti locali e globali da una prospettiva ecologica
No full textLa dissertazione si situa nel grande ambito di ricerca legato all’applicazione e all’utilizzo degli strumenti informatici nella città contemporanea. La crisi da cui muove è almeno duplice, da una parte la questione ecologica, dall’altra quella tecnologica, tanto alla scala locale che a quella globale. La ricerca ha una struttura tripartita: nella prima parte viene definito un quadro di riferimento a partire da tre parole chiave, nella seconda vengono approfondite tre tecnologie alla scala urbana e nell’ultima vengono presentati quattro casi studio ritenuti significativi
Social technology enhancing the town centre management attractiveness
Full text linkThe article describes the social technology’s role in the TCM attractiveness from the retailers’ perspective. The exploratory research experience in Sweden during different periods between 2012 and 2016 includes contributions of the literature, direct interviews and analysis of the TCM’s websites. The state-of-the-art of social commerce perception by managers and retailers is defined, and specific evidences are given through research. An interpretation of the concept of attractiveness of the TCM is presented to explain how social commerce could affect this property. Dissonance between opinions and statements of TCM stakeholders are discussed, and the will to use social commerce to increase opportunities for TCM is, in general, declared by retailers, but it is not realized in practice in management activities. A comparative empirical exploration between different countries could be conducted in future. This paper explores the actual situation in the use of website sustaining that the social commerce and the social networks are able to go beyond the supporting of commerce activity and they are able to support the TCM attractiveness and place attachment
Cohabiting with the Logical Paradoxes: A Negative Assessment and a Proposal
Full text linkAt the commonsensical level of the manifest image, we seem to take for granted
logical laws of all sorts, including classical logic (CL) and naive principles of truth
and predication (TP), which, however, generate logical paradoxes such as the liar,
Russell’s paradox and Curry’s paradox. The formal logic of the scientific image
comes to the rescue by proposing many competing formal systems that restore consistency,
by sacrificing either principles of CL or principles of TP. We wish to explore
a different path, which aims at saving both CL and TP, and deals with the
paradoxes when they come to the fore, without swallowing contradictions or explosion.
We consider the viability of Batens’ Inconsistency-Adaptive Logic (IAL)
to pursue this goal and we end up with a negative assessment. We then sketch an
alternative proposal that incorporates IAL’s distinction between provisional and
final derivability
Finding minimal unsatisfiable subformulae in satisfiability instances
No full textA minimal unsatisfiable subformula (MUS) of a given CNF is a set of clauses which is unsatisfiable, but becomes satisfiable as soon as we remove any of its clauses. In practical scenarios it is often useful to know, in addition to the unsolvability of an instance, which parts of the instance cause the unsolvability. An approach is here proposed to the problem of automatic detection of such a subformula, with the double aim of finding quickly a small-sized one. We make use of an adaptive technique in order to rapidly select an unsatisfiable subformula which is a good approximation of a MUS. Hard unsatisfiable instances can be reduced to remarkably smaller problems, and hence efficiently solved, through this approach
On-line Commerce and Town Centre Retailers’ Experience
Full text linkThis paper is an attempt to develop a new way to sell products or services for retailers within town centres. An analysis of the literature revealed that the use of the Internet and digital commerce strategies are rarely used as tools to revitalize urban retail and develop a multidimensional experience of place. Thus, this paper aims to highlight which new modes of online commerce—e-commerce, s-commerce and m-commerce—are more suitable than others to help town centre retailers revitalize the place where they work. The research questions are as follows: 1) What are the origins of the growth and development of new forms of selling? and 2) How might town centre retailers integrate new forms of selling with traditional retailing? In answering the previously stated questions, this paper provides a proposed model that, by combining physical and virtual means to sell products and services, can provide specific strengths in revitalizing town centres
Minimum-Time Spacecraft Attitude Motion Planning Using Objective Alternation in Derivative-Free Optimization
Full text linkThis work presents an approach to spacecraft attitude motion planning which guarantees rest-to-rest maneuvers while satisfying pointing constraints. Attitude is represented on the group of three dimensional rotations. The angular velocity is expressed as weighted sum of some basis functions, and the weights are obtained by solving a constrained minimization problem in which the objective is the maneuvering time. However, the analytic expressions of objective and constraints of this minimization problem are not available. To solve the problem despite this obstacle, we propose to use a derivative-free approach based on sequential penalty. Moreover, to avoid local minima traps during the search, we propose to alternate phases in which two different objective functions are pursued. The control torque derived from the spacecraft inverse dynamics is continuously differentiable and vanishes at its endpoints. Results on practical cases taken from the literature demonstrate advantages over existing approaches
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
