This study examines how art museumsh245790310/xxlarge8216.gif" alt="lsquo" align="BASELINE" BORDER="0">purchasing policy influences the auction prices ofpaintings. Using a cross section of non-speculativetransactions during the period 1820–1970, we findconsiderable empirical support for the hypothesisthat public museums outside the U.S. pay above averageprices in auction markets providing higher thanaverage yields to private sellers. The typical U.S.private museums appear to be more restricted byfinancial constraints and the development of thegeneral economic conditions than their publiccounterparts.  相似文献   

Kinship,Camaraderie and Contestation: Fāṭimid Relations with the Ashrāf in the Fourth/Tenth Century.     

Shainool Jiwa 《Al-Masaq: Islam & the Medieval Mediterranean》2016,28(3):242-264

The founding of the Fā?imid caliphate across the southern Mediterranean, and then in Egypt, Syria and the ?ijāz at the turn of the fourth/tenth century, necessitated its negotiation with the ashrāf, those who claimed lineal descent from the Prophet Mu?ammad, and who by this time had gained significant influence as a social class based on their charismatic descent. While other dynastic powers fostered relationships with various members of the ashrāf, the Fā?imid–ashrāf dynamics were distinctive in that the Fā?imids legitimised their rule as Ismā?īlī Shī?ī imām-caliphs, based on their claim of descent from the Prophet Mu?ammad, and as the sole successors to his authority and leadership over the Islamic world. Consequently, Fā?imid–ashrāf relations were permeated by fraternal camaraderie as well as by competing contestations based on their shared claim to Prophetic lineage.  相似文献

Aplicación empírica de un indicador bibliométrico basado en el índice h     

《Cultura y Educación》2013,25(2):297-313

Resumen

El índice h es uno de los indicadores bibliométricos empleados para estimar el éxito de la carrera profesional de un investigador. Se trata de un indicador que combina producción e impacto, y que elimina los sesgos provocados por las colas de la distribución de citas. Sin embargo, este indicador presenta limitaciones a la hora de discriminar entre investigadores con diferentes hábitos de publicación, penalizando a aquellos más selectivos, que no destacan por el número de publicaciones pero sí por el alto número de citas recibidas, frente a los grandes productores. En este trabajo se presenta una aplicación empírica de los indicadores de entorno, un complemento del índice h que considera la zona intermedia de la distribución de citas.  相似文献   

Shi‘ism and the Early Dinars of the Fāṭimid Imam-caliph al-Mu‘izz li-dīn Allāh (341–365/952–975): An Analytic Overview     

Sherif Anwar 《Al-Masaq: Islam & the Medieval Mediterranean》2010,22(3):259-278

The Imam-caliph al-Mu‘izz al-Dīn Allāh undertook a series of monetary changes which were to have a monumental impact on all future Fā?imid coinage, would lead to many imitations even after the dynasty had fallen, and create an easily identifiable pattern that attracted medieval merchants and modern collectors. The fact that al-Mu‘izz's coinage went through three stages with slight variations in the wording and layout indicates that he was determined to create a new model for Fā?imid coinage which would distinguish it from the Aghlabid and ‘Abbāsid coinage that preceded and competed with it. In contrast, Sijilmasa coinage was so conservative in layout due to its role in the African trade.  相似文献
