Ă€ la recherche des Donatello perdus, de Florence Ă Berlin
Voici un siècle que la recherche la plus célèbre de la littérature mondiale est celle du temps perdu. Dans la quête de Marcel Proust, les arts visuels jouent un rôle clef, et tout particulièrement les peintures des Maîtres anciens: une fresque de Botticelli ou un panneau de Vermeer peuvent, dans le roman proustien, apporter une solution décisive aux deux grands mystères de l’existence que sont l’amour etl’art. C’est face à une reproduction d’un détail d’une fresque peinte par Sandro Botticelli dans la chapelle Sixtine que Charles Swann tombe amoureux de la demi-mondaine Odette de Crécy, dont il installe une photographie sur son bureau, à côté du visage de Botticelli1. Des années plus tard, c’est devant la Vue de Delftde Vermeer, appartenant au Mauristhuis de La Haye mais prêtée au musée de l’Orangerie le temps d’une exposition, que le célèbre écrivain Bergotte comprendra, au soir de sa vie, «comment [il] aurai[t] dû écrire». Et Bergotte de poursuivre son célèbre monologue intérieur
Masolino et Masaccio : technique et style
Comment un génie visionnaire comme Masaccio a-t-il bien pu collaborer durant toute sa courte carrière avec un peintre aussi passéiste que Masolino ? Cette question, aujourd’hui inavouable, a longtemps tourmenté les historiens de l’art, qui furent nombreux à délaisser la traditionnelle approche monographique pour une étude conjointe, des fondamentaux Fatti di Masolino e di Masaccio de Roberto Longhi à l’imposant ouvrage de Paul Joannides. Ces dernières années, un important projet de recherche,..
Sustainability program brands: Platforms for collaboration and co-creation
While CSR and Sustainability have been widely debated topics over the past decades, there is still evidence of unethical practices by businesses, as witnessed through corporate scandals across a number of industry sectors. This highlights the need for firms to collaborate to actively prevent malpractices and instead find ways to improve standards along the whole value chain. With the increased pressure from various stakeholders, calling for firms to address these issues in a collaborative and holistic manner, the development of models facilitating collaboration is vital. Taking a communication perspective, this paper seeks to improve the knowledge on how organisations can manage diverse stakeholders to improve value chain collaboration towards more sustainable practices. Based on a multiple case study methodology, involving in-depth interviews with senior directors in the food and drink value chain, a framework is developed, depicting the value of a branded sustainability program as a useful platform for stimulating collaboration and co-creation from diverse and/or competing stakeholders. The framework builds on, and contributes to several literature strands including CSR/Sustainability communication, Coopetition and Branding
Safety and Efficacy of the Addition of Lapatinib to Perioperative Chemotherapy for Resectable HER2-Positive Gastroesophageal Adenocarcinoma: A Randomized Phase 2 Clinical Trial
Importance: Perioperative chemotherapy and surgery are a standard of care for operable gastroesophageal adenocarcinoma. Anti-HER2 therapy improves survival in patients with advanced HER2-positive disease. The safety and feasibility of adding lapatinib to perioperative chemotherapy should be assessed.
Objectives: To assess the safety of adding lapatinib to epirubicin, cisplatin, and capecitabine (ECX) chemotherapy and to establish a recommended dose regimen for a phase 3 trial.
Design, Setting, and Participants: Phase 2 randomized, open-label trial comparing standard ECX (sECX: 3 preoperative and 3 postoperative cycles of ECX with modified ECX plus lapatinib (mECX+L). This multicenter national trial was conducted in 29 centers in the United Kingdom in patients with histologically proven, HER2-positive, operable gastroesophageal adenocarcinoma. Registration for ERBB/HER2 testing took place from February 25, 2013, to April 19, 2016, and randomization took place between May 24, 2013, and April 21, 2016. Data were analyzed May 10, 2017, to May 25, 2017.
Interventions: Patients were randomized 1:1 open-label to sECX (3 preoperative and 3 postoperative cycles of 50 mg/m2 of intravenous epirubicin on day 1, 60 mg/m2 intravenous cisplatin on day 1, 1250 mg/m2 of oral capecitabine on days 1 through 21) or mECX+L (ECX plus lapatinib days 1 through 21 in each cycle and as 6 maintenance doses). The first 10 patients in the mECX+L arm were treated with 1000 mg/m2 of capecitabine and 1250 mg of lapatinib per day, after which preoperative toxic effects were reviewed according to predefined criteria to determine doses for subsequent patients.
Main Outcomes and Measures: Proportion of patients experiencing grade 3 or 4 diarrhea with mECX+L. A rate of 20% or less was considered acceptable. No formal comparison between arms was planned.
Results: Between February 2013, and April 2016, 441 patients underwent central HER2 testing and 63 (14%) were classified as HER2 positive. Forty-six patients were randomized; 44 (24 sECX, 20 mECX+L) are included in this analysis. Two of the first 10 patients in the mECX+L arm reported preoperative grade 3 diarrhea; thus, no dose increase was made. The primary endpoint of preoperative grade 3 or 4 diarrhea rates were 0 of 24 in the sECX arm (0%) and 4 of 20 in the mECX+L arm (21%). One of 24 in the sECX arm and 3 of 20 in the mECX+L arm stopped preoperative treatment early, and for 4 of 19 in the mECX+L arm, lapatinib dose was reduced. Postoperative complication rates were similar in each arm.
Conclusions and Relevance: Administration of 1250 mg of lapatinib per day in combination with ECX chemotherapy was feasible with some increase in toxic effects, which did not compromise operative management.

The prognostic significance of allelic imbalance at key chromosomal loci in oral cancer
Forty-eight primary oral squamous cell carcinomas (SCC) were screened for allelic imbalance (AI) at 3p24–26, 3p21, 3p13, 8p21–23, 9p21, 9q22 and within the Rb, p53 and DCC tumour suppressor genes. AI was detected at all TNM stages with stage 4 tumours showing significantly more aberrations than stage 1–3. A factional allelic loss (FAL) score was calculated for all tumours and a high score was associated with development of local recurrence (P = 0.033) and reduced survival (P = 0.0006). AI at one or more loci within the 3p24–26, 3p21, 3p13 and 9p21 regions or within the THRB and DCC genes was associated with reduced survival. The hazard ratios for survival analysis revealed that patients with AI at 3p24–26, 3p13 and 9p21 have an approximately 25 times increase in their mortality rate relative to a patient retaining heterozygosity at these loci. AI at specific pairs of loci, D3S686 and D9S171 and involving at least two of D3S1296, DCC and D9S43, was a better predictor of prognosis than the FAL score or TNM stage. These data suggest that it will be possible to develop a molecular staging system which will be a better predict of outcome than conventional clinicopathological features as the molecular events represent fundamental biological characteristics of each tumour. © 1999 Cancer Research Campaig

Sources of stakeholder salience in the responsible investment movement: why do investors sign the Principles for Responsible Investment?
Since its inception in 2006, the United Nations-backed Principles for Responsible Investment (PRI) have grown to over 1300 signatories representing over $45 trillion. This growth is not slowing down. In this paper, we argue that there is a set of attributes which make the PRI salient as a stakeholder and its claim to sign the six PRI important to institutional investors. We use Mitchell et al.’s (Acad Manag Rev 22:853–886, 1997) theoretical framework of stakeholder salience, as extended by Gifford (J Bus Eth 92:79–97, 2010). We use as evidence confidential data from the annual survey of signatories carried out by the PRI in a 5-year period between 2007 and 2011. The findings highlight pragmatic and organizational legitimacy, normative and utilitarian power, and management values as the attributes that contribute most to the salience of the PRI as a stakeholder
Secondary Stakeholder Influence on CSR Disclosure: An Application of Stakeholder Salience Theory
The aim of this study is to analyse how secondary stakeholders influence managerial decision-making on Corporate Social Responsibility (CSR) disclosure. Based on stakeholder salience theory, we empirically investigate whether differences in environmental disclosure among companies are systematically related to differences in the level of power, urgency and legitimacy of the environmental non-governmental organisations (NGOs) with which these companies are confronted. Using proprietary archival data for an international sample of 199 large companies, our results suggest that differences in environmental disclosures between companies are mainly associated with differences between their environmental stakeholders’ legitimacy. The effects of power and urgency are of an indirect nature, as they are mediated by legitimacy. This study improves our understanding of CSR disclosure by demonstrating that, next to the well-documented effect of company characteristics, stakeholder characteristics are also important. Besides, it provides scarce empirical evidence that not only primary stakeholders, but also secondary stakeholders are influential with regards to management decision-making. And more specifically, it offers insight into why some stakeholder groups are better able to influence disclosure decisions than other. The results also have important practical implications for managers of both environmental NGOs and large companies. For managers of environmental NGOs the results provide evidence of the most successful tactics for having their environmental information demands satisfied by companies. For company management the results provide insights into the most important stakeholder characteristics, on the basis of which they may develop strategies for proactively disclosing environmental information
Stakeholder Salience for Small Businesses : A Social Proximity Perspective
This paper advances stakeholder salience theory from the viewpoint of small businesses. It is argued that the stakeholder salience process for small businesses is influenced by their local embeddedness, captured by the idea of social proximity, and characterised by multiple relationships that the owner-manager and stakeholders share beyond the business context. It is further stated that the ethics of care is a valuable ethical lens through which to understand social proximity in small businesses. The contribution of the study conceptualises how the perceived social proximity between local stakeholders and small business owner-managers influences managerial considerations of the legitimacy, power and urgency of stakeholders and their claims. Specifically, the paradoxical nature of close relationships in the salience process is acknowledged and discussed.Peer reviewe
