PIECING TOGETHER THE STORY OF A PAIR OF MAKRON’S FRAGMENTED CUPS

In 2022, an Athenian red-figured cup attributed to Makron was returned to Italy by New York’s Metropolitan Museum of Art. The cup had been acquired in fragments, through purchase and gift, from multiple sources over several years, starting with two fragments from the restorer Fritz Bürki in 1978. A second cup, also attributed to Makron, was acquired in a parallel way. The sources for the fragments from both cups point to galleries collectors and donors – Summa Galleries, Frieda Tchachos, Elizabeth Hecht, and Dietrich von Bothmer – who have been associated with other material that has been repatriated to Italy in recent years. It is suggested that some of the incised ‘signatures’ by Hieron that are found on cups attributed to Makron may have been applied since antiquity.     

A STUDY OF CHINESE PORCELAIN RAW MATERIALS FOR DING,XING, GONGXIAN AND DEHUA WARES*

The raw material used largely determines the type and quality of porcelain produced. Twenty-three raw materials used for making Ding, Xing, Gongxian and Dehua porcelain bodies were studied using principal component analysis. Results show that for Dehua wares, only one raw material was used. For Ding wares, although there were many possible raw materials, the use of one alone is unlikely. Lingshan clay was the main raw material but it has to be mixed with other raw materials: Pinjiawa clay, quartz, feldspar and dolomite. The Xing pieces can be divided into three groups and Gongxian wares into two groups, which are discussed in detail.     

Public Policy and Emerging Sources of Technology and Technical Information Available to Industry

As technologies grow in complexity, firms often target their internal R&D resources on core competencies and utilize outside sources for supporting knowledge and technology. Where do firms turn to find such resources? This paper reports the perceptions of technology transfer managers in United States manufacturing firms toward federal and university labs and identifies the types of farms that are better positioned to utilize externally available technological resources. Based on replies from research-intensive companies within the United States, the authors find that larger firms with high research and development (R&D) budgets tend to ascribe greater significance to external sources than do smaller ones. Also, companies spending over $500 million in R&D rank universities the most significant external source of knowledge, followed by V S.-based firms, and then foreign firms.     

Policy Gridlock in Waste Management

Current federal hazardous and low-level radioactive waste management policies (under conjoint federalism) fail to balance national concerns for consistency with state concerns for equity, discretion, and adequate resources. Congress should expand conjoint federalism to permit states to charge differential fees on imported hazardous waste as it does for low-level radioactive waste. For low-level radioactive waste, clarification of the "take title" issue makes the present framework for state discretion implementable, given sufficient time.     

Marital instability in a rural population in south-west Uganda: implications for the spread of HIV-1 infection

"The aim of this study was to examine people's beliefs about the causes of marital instability in a rural population cohort in south-west Uganda. Results from a baseline survey of HIV-1 infection in the cohort of over 4,000 adults (over 12 years old) showed a twofold increase in risk of infection in divorced or separated persons when compared with those who are married. A purposive sample of 134 respondents (seventy-two males, sixty-two females) selected to represent different ages, religions and marital status were asked in semi-structured interviews to comment on the reasons for continuing marital instability in their community. The most common reasons suggested for marital instability were sexual dissatisfaction, infertility, alcoholism and mobility....HIV infection was not mentioned as a direct cause of separation, but a small independent study revealed that seven out of ten couples separated on learning of a positive HIV test result of one or both partners. Marital instability is not uncommon in this population; there is evidence that HIV infection is making the situation worse." (SUMMARY IN FRE)     

A PILOT STUDY IN NON-CONTACT LASER PHOTOTHERMAL ARCHAEOMETRY OF ANCIENT STATUARY PEDESTAL STONES FROM CYPRUS

Several samples of geological stones from statuary pedestals found in various archaeological sites in Cyprus have been characterized using non-contact laser infrared photothermal radiometry. Thermal diffusivities and effective optical absorption coefficients were calculated using a one-dimensional thermal-wave model. The mean values and standard deviations were tabulated and comparisons were made with lithographic and petrographic studies of the samples. Good correlations were found, thus demonstrating that laser photothermal archaeometry is a promising methodology for the accurate, potentially non-destructive and convenient characterization of the origins of ancient stones in Cyprus and other geological and archaeological sites.
