"The Sacred Heart of Jesus", a painting by Massard depicting Jesus Christ in iconic portrait, [s.d.]
No full textPhotograph of "The Sacred Heart of Jesus", a painting by Massard depicting Jesus Christ in iconic portrait, [s.d.]. Christ is pictured in bust, framed by an oval. His hands are held in front of him, his right pointing upward, his left gesturing to the luminescent heart superimposed at the center of his chest. The heart itself is bound in a twist of thorns, while a cross rises from its top. A filagree halo circumscribes Christ's head

Fuel Transitions, Supply Crises and Climate Change in Lowland Scotland c.1200-c.1550
No full textThis paper explores the evidence for fuel transitions affecting three of Scotland’s major lowland urban communities – Aberdeen, Perth and Edinburgh – from c.1200 to c.1500. It examines the historical record evidence for pressure on the traditionally preferred fuel, wood, by the early 1200s and for the increasing importance of peat as the main fuel for domestic and industrial activities through the thirteenth century. This discussion includes a consideration of the wider impact of regional availability of wood in the context of all three urban centres. The principal focus of the paper is on the peat to coal transition that began to occur in the central lowlands in the fourteenth century and which became increasingly evident in the fifteenth. Discussion concentrates on the regional differences in response to fuel supply crises by urban authorities, principally through prescriptive legislation and market regulation, and to the development of long-distance trade in bulk fuel to regions with limited naturally available resources. This discussion is further informed by consideration of the impact on such efforts of climatic deterioration across the same period and weather-related factors affecting choices in fuel-use

Approche thermodynamique des phénomènes de dissolution. Aspect cinétique en système fermé et comparaison système ouvert˗système fermé dans le cas de l'albite
No full textThe dissolution of any mineral in a weathering solution is governed by a simple kinetic law, available for either open or closed system (Massard, 1977) :
v = k. A'/T
where v is the kinetics of the dissolution, A' the chemical affinity of the associated reaction, T the temperature and k a constant proportional to k₀, characteristic parameter of the mineral. Here, this relation is applied to albite, mineral studied in closed system by Lagache (1965) and in open system by ourselves. Both of these experimental approaches, corresponding to different constraints and conditions of T and P, confirm the theoretical anticipations and lead to corroborative estimations of k₀ on the studied interval of temperature (85 °C to 200 °C). We deduct from these studies a simple method of experimental determination of k₀ in open system.La dissolution d'un minéral dans une solution altérante est régie par une loi cinétique simple, valable que le système soit ouvert ou fermé (Massard, 1977) :
v = k.A'/T
où v est la cinétique de la dissolution, A' l'affinité chimique de la réaction associée, T la température et k une constante proportionnelle à k₀, paramètre caractéristique du minéral. Cette relation est ici appliquée à l'albite, minéral étudié en système fermé par Lagache (1965) et en système ouvert par nous-mêmes. Ces deux approches expérimentales, qui correspondent à des contraintes et des conditions de T et P différentes, vérifient les prévisions théoriques et conduisent à des estimations de k₀ concordantes sur l'intervalle de température étudié (85 °C à 200 °C). Nous déduisons de ces études une méthode simple de détermination de k₀ en système ouvert.Massard Pierre. Approche thermodynamique des phénomènes de dissolution.

The geography of innovation : challenge to technology policy within regions
No full textThe "Geography of Innovation" is based on the desire to give empirical foundations to the explanations behind the pronounced spatial polarisation of the innovation activities. It focuses on an attempt to measure the spatial dimension of knowledge externalities, in order to reveal their role in the organisation of research systems. The aim of this paper is to survey this empirical literature in order to highlight the main results interesting for the innovation policy. This analysis emphasises one main role of technology policy : supporting the institutions which generate knowledge and learning. These are found at various territorial levels, especially within the European Union. Here attention is drawn to the regional intervention level.technology policy, geography of innovation, knowledge externalities, European regions, knowledge-based economy
Proximity and Innovation through an 'Accessibility to Knowledge' Lens
No full textMassard N. and Mehier C. Proximity and innovation through an 'accessibility to knowledge' lens, Regional Studies. The aim of this paper is to improve understanding of the spatial diffusion process of knowledge in terms of accessibility, and also to elaborate a new measurement and evaluation tools adapted to a concrete estimation of these phenomena. This approach offers ways of giving an operational content to the concept of proximity. The 'potential functions' used to measure geographical accessibility is enriched with the integration of the characteristics of knowledge diffusion, namely sources of externalities/knowledge, ways of transmission, and absorptive capacity. The paper especially focuses on the relational and strategic dimensions of proximity by using some developments from social networks analysis. Such an approach leads to new empirical models for estimating the determinants of accessibility to knowledge. [image omitted] Massard N. et Mehier C.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.
