Viscoelastic and mechano-sorptive studies applied to the conservation of historical violins: A case study of the Guarneri “del Gesù” violin (1743) known as the “Cannone”

To assess the possible effects of mechanical loading on the conservation of historical wooden musical instruments, a research project was carried out on the violin Guarneri “del Gesù” (1743), known as the “Cannone”. This paper refers to the results obtained by studying the deformations to which a violin is subjected after being tuned, with special attention to the viscous and mechano-sorptive behaviour (as in a concert environment for example). The amount of viscoelastic creep was quantified under normal tuning conditions, and the mechano-sorptive creep was quantified using a dead mass resulting in 55% of the elastic deformation obtained after tuning. The viscoelastic and mechano-sorptive deformations were clearly observed. These deformations were completely recovered once the violin was unloaded, demonstrating that this violin structure is appropriately dimensioned for the applied stresses.     

The new digital face of the consumerist mediator: the case of the ‘Yuka’ mobile app

ABSTRACT

Drawing on Mallard’s contribution [2007. Performance testing: dissection of a consumerist experiment. The sociological review, 55 (2), 152–172] on the work undertaken by consumerist journals to evaluate products independently from the mediation of market players, our goal is to characterize the new digital form of the consumerist mediator by using a specific case: Yuka, a mobile application (app) enabling consumers to obtain alternative health labeling on foodstuffs. Relying on interviews, observations of the app and analysis of underlying product databases and reports on food labeling issues, we examine the new forms of consumer-to-market interactions brought about by the app, the conceptions of health inscribed in its product qualification algorithm and the operation of the database on which it is based. Our position is threefold: firstly, we argue that the relationship between the consumer and the market established by Yuka is less distant than the one established by traditional consumerist mediators. Secondly, in the case of Yuka, we argue that the market relationship is based on a compromise between scientific logic, technological uncertainty and consumer concerns. Thirdly, we claim that this case demonstrates new ways for consumerist prescribers to politically intervene on markets, but that the potential of the intervention is tied to new issues related to the openness of product data.     

Institutional Expansion and Scientific Development in the Periphery: The Structural Heterogeneity of Argentina’s Academic Field

The relationship between “marginal” and “mainstream” science has, in recent decades, become a matter of discussion. Traditional perspectives must be reexamined in the wake of transformations in the international circulation of knowledge and the subsequent diversification of scientific “peripherality”. Argentina represents an interesting case with which to explore the structure of “peripheral centres” and new forms of scientific development. While it has recently experienced an expansion in terms of institutionalization, professionalization, and internationalization, that process has been coupled with entrenchment of existing institutional asymmetries and persistent intra-national inequalities; academic prestige is distributed according to opposite principles of legitimation (local/international). Our main task is to explore the current state of research capacities pursuant to that expansion in order to analyze the diverse styles in which knowledge is produced. In our analysis, we make critical use of Bourdieu’s concept of field and the Latin American category of “structural heterogeneity,” while also focusing on the question of circulation. The paper outlines how professionalization has developed locally over time, and the historical tension between the National Council for Scientific and Technical Research and the public universities. It describes the current structure of the scientific field in terms of researchers, institutes, publishing circuits, and institutional evaluative cultures. It focuses on geographical asymmetries in order to assess the distribution of new human and material resources throughout the country. Finally, it addresses the current situation under the new government, and raises concern over recent regressive actions.     

A combination of NDT methods for the restoration of monumental façades: The case study of Monte di Pietà (Naples,Italy)

The paper focuses on an interdisciplinary research project concerning the preservation of the XVII century monumental building of Monte di Pietà in Naples, Italy. The building underwent a series of restorations being the structural walls affected by humidity and cracks. The importance of this monumental building in the historical city center of Naples led to design an extensive surveying program to provide the designers of strengthening with a detailed investigation of the geometry of the entire structure, and particularly of the entrance façade, with great details on several materials, thicknesses and restraints. A preliminary investigation was performed on the historical phases of this monumental building to have a clear knowledge of its vicissitudes, and then in situ structural assessment included 3D laser scanner techniques probing radar, in situ stress measures. This surveying phase was crucial especially for the subsequent Finite Elements modeling (F.E.M.) of the façade. The scope of the numerical refined analyses was to evaluate the state of stress in the structural elements of the façade putting in evidence structural ‘weak points’ and finally to design a retrofit intervention having a detailed map of the ‘intervention areas’. The theoretical damage assessment has been compared with on-site assessment and in situ stress measures. The damage primarily concerned the entrance façade and its valuable decorations. Furthermore, the basic principles for the design of the strengthening have been discussed.     

Autographs and the global art market: the case of hedonic prices for French autographs (1960–2005)

The market for autographs has become more open to international buyers since 1990. Our data set features a large sample of store and auction sales for selected authors every 5 years from 1960 to 2005. The estimation of a hedonic price function shows that page count, type of author, date and type of the document conditionally to author explain more than three quarters of the price differences. The apparent price of autographs increased by 7.7 % per year during the period, while the hedonic price index increased by 7.9 % on average. With a supply function responsive to market valuation, as well French autograph prices seemingly showing trend similar to art market index, the French autograph market has become more integrated in the global art market.     

Ethical consumption applications as failed market innovations: exploring consumer (non) acceptance of ‘quasi’ market devices

ABSTRACT

In this paper, I conceptualise ethical consumption applications (ECAs) as market innovations inflected in processes of configuring market actors and market (re)framings. The introduction of ECAs through the work of civil society is not only about changing frames of market exchange, but also work in the register of making ‘good consumers’ and consumers as ‘agents of change’ and moralising markets. Thus, a more accurate concept for these devices is suggested: ‘quasi’ market devices. The main aim of this paper is to analyse how consumers attached to and resisted use of ECAs designed to assist in product choices and shape responsible everyday practices. Based on qualitative fieldwork in Sweden, the article applies a methodology grounded in Science and Technology-inspired market studies in combination with Consumer Culture Theory’s (CCT) interest in identity work and sense-making associated with technology consumption. Although available at the time of the empirical data collection period of the study, all three apps were off the market during the analytic work of this paper; a major argument for focusing on barriers to acceptance of the apps and trying to conceptualise how such non-acceptance can be understood.     

Structural engineering and geology applied to the static problems of the Etruscan “Tomba dell’Orco” (Tarquinia,Central Italy)

The Etruscan Tomba dell’Orco was discovered in 1868. However, soon after discovery, part of its ceiling collapsed. An investigation was thus conducted with a view to assessing its safety conditions and permitting visitors’ access. Petrographic and physico-mechanical features of the local weak sandstones and mechanically more resistant calcareous sandstones “macco” were determined. Field mapping, drill-holes and geophysical prospecting helped reconstruct the stratigraphy of the volume where the tomb was excavated. The stability of the tomb basement is given by a thick macco layer. A few dm macco layer was identified above the ceiling. A model was then prepared with the Plaxis 2D V8.6 software. The safety coefficients calculated along two cross-sections of the tomb indicated that the margins for the tomb stability are reasonable.     

Laser scanning and digital imaging for the investigation of an ancient building: Palazzo d’Accursio study case (Bologna,Italy)

This paper describes a scientific approach aimed at studying the ancient part of Palazzo d’Accursio (Bologna, Italy), a masonry building which is part of the Italian cultural heritage. Laser scanning and the inspection of digital images are used to detect traces of restoration works and other interesting features related to both architectural marks and natural or anthropic events. One of the main elements of the method is the analysis of residual maps, obtained by computing the differences between the point coordinates of the façade and reference fit planes. The obtained results, based on both radiometric and geometrical analysis, are used to provide a reasonable hypothesis as to the original configuration of the studied building, while taking into account the available historical information about the constructive phases of the building.     

The Scientific Field During Argentina’s Latest Military Dictatorship (1976–1983): Contraction of Public Universities and Expansion of the National Council for Scientific and Technological Research (CONICET)

This study looks at some of the traits that characterized Argentina’s scientific and university policies under the military regime that spanned from 1976 through 1983. To this end, it delves into a rarely explored empirical observation: financial resource transfers from national universities to the National Scientific and Technological Research Council (CONICET, for its Spanish acronym) during that period. The intention is to show how, by reallocating funds geared to Science and Technology, CONICET was made to expand and decentralize to the detriment of universities. This was the primary tool used by the military regime to thwart higher education’s research development, bolstering research efforts at other realms. Thus, CONICET grew in budget, number of researchers, and staff size, creating new research institutes, while national universities struggled with reduced funding and were forced to shut down their institutes and programs. As a result, CONICET virtually concentrated all scientific research, foregoing the knowledge accumulated at universities, which drove a wedge between both institutions. This military approach to science and technology policy-making is discussed, bearing in mind the notion of dependence—both in terms of the state’s intervention in the inner workings of the scientific-university field as well as regarding the role played by international financial support in scientific research development.     

Measuring allocative efficiency in Cultural Economics: the case of “Fundación Princesa de Asturias” (The Princess of Asturias Foundation)

The literature on Cultural Economics provides us with some examples for the measurement of technical efficiency. However, there are few case studies dedicated to the analysis of allocative efficiency. The aim of this paper is to fill this gap by incorporating a methodology that analyses both technical and allocative efficiency. We use the Shephard’s distance function, particularly suitable when affronted with non-profit-making firms or institutions that are not interested in cost minimization. As an empirical application, we analyse the efficiency of Fundación Princesa de Asturias (PAF), a Spanish non-governmental organization devoted to promoting the cultural, scientific and humanistic values of universal heritage, the period of study being 1988–2012. Our findings suggest that PAF could have used 7% less inputs to achieve the same level of output. On the other hand, we have found allocative inefficiency. Concretely, the input for other expenditures appears to have been over-utilized in relation to both the inputs for labour and current assets, with labour in turn being over-utilized in relation to current assets. Moreover, our results indicate that both technical and allocative efficiency have clearly improved during the period analysed. In summary, our empirical application shows how distance function methodology can be successfully implemented to measure allocative efficiency in cultural firms and institutions.     

Her Holiness: The Purohitas of Pune,India: Female Hindu Priests as Embodied,Emotional–Spiritual,and Aesthetic (Performative) Laborers

Abstract

Female priests are a relatively new phenomenon in Hindu Indian culture. Positioned as outsiders within, they have been marginalized from the male-dominated priestly profession, even as they continue to challenge normative expectations surrounding their unconventional occupational choice. This study presents findings from a multi-methods qualitative study that, in addition to analyzing media reports about female Hindu priests of Pune city, interviewed 12 practicing priests. Utilizing data-driven lenses of embodied, emotional–spiritual, and aesthetic (performative) labor, findings from this study revealed how participants communicatively and strategically diffused resistance and redefined competence by negotiating contradictory aspects of their professional realities.
