MoMA and Nazi-Era Art Restitution: Contexts and Thoughts for the Future

Holocaust-era restitution remains one of many issues troubling the museum world in recent years. These types of cases expose the persistent concern over ownership of the material culture held within museums that, in part, make up the philosophies and cultural traditions underlying them. In the wake of the 1998 Washington Conference on Holocaust-Era Assets, the American museum community asserted they could properly regulate restitution claims without need for an independent commission, as was being established in many European countries at the time. This thesis reflects upon developments following 1998 and assesses the current value systems of American museums and their commitment to the international issue of restitution by examining the actions and policies of the Museum of Modern Art (MoMA) in New York City. Since the establishment of the Washington Conference Principles, museums holding Nazi-era misappropriated works have continually tried to mischaracterize applicable policy. MoMA has not only experienced difficulties resulting from its early acquisitions, but in recent years, it has been very visible in a series of recent restitution claims and debates. This thesis argues that MoMA could set a different example, through its statements and actions, for Holocaust-era restitution by acknowledging its historical complicity and urging other institutions and the public to go beyond notions of possession. MoMA is an institution that has undoubtedly become more complex and internationally implicated in the past few years. However, the issue of restitution and its inadequate treatment in the United States has brought into scrutiny museums like MoMA, impacting upon the public’s willingness to place confidence in the museum in its role as trustee of works of art. I contend that, should MoMA wish to maintain its position of influence in the museum system in the United States and abroad, it needs to become more invested in the future and be conscious of how it is transmitting memory and the meaning of the past to an increasingly transnational and diverse public. Although this case study examines the treatment of Nazi-looted art in one American institution, the issues under consideration have transferable moral significance across the larger debate of stolen cultural property

The significant impact of education, poverty, and race on Internet-based research participant engagement

PURPOSE: Internet-based technologies are increasingly being used for research studies. However, it is not known whether Internet-based approaches will effectively engage participants from diverse racial and socioeconomic backgrounds. METHODS: A total of 967 participants were recruited and offered genetic ancestry results. We evaluated viewing Internet-based genetic ancestry results among participants who expressed high interest in obtaining the results. RESULTS: Of the participants, 64% stated that they were very or extremely interested in their genetic ancestry results. Among interested participants, individuals with a high school diploma (n = 473) viewed their results 19% of the time relative to 4% of the 145 participants without a diploma (P < 0.0001). Similarly, 22% of participants with household income above the federal poverty level (n = 286) viewed their results relative to 10% of the 314 participants living below the federal poverty level (P < 0.0001). Among interested participants both with a high school degree and living above the poverty level, self-identified Caucasians were more likely to view results than self-identified African Americans (P < 0.0001), and females were more likely to view results than males (P = 0.0007). CONCLUSION: In an underserved population, engagement in Internet-based research was low despite high reported interest. This suggests that explicit strategies should be developed to increase diversity in Internet-based research. Genet Med 19 2, 240–243

Temporal scale‐dependence of plant–pollinator networks

The study of mutualistic interaction networks has led to valuable insights into ecological and evolutionary processes. However, our understanding of network structure may depend upon the temporal scale at which we sample and analyze network data. To date, we lack a comprehensive assessment of the temporal scale-dependence of network structure across a wide range of temporal scales and geographic locations. If network structure is temporally scale-dependent, networks constructed over different temporal scales may provide very different perspectives on the structure and composition of species interactions. Furthermore, it remains unclear how various factors – including species richness, species turnover, link rewiring and sampling effort – act in concert to shape network structure across different temporal scales. To address these issues, we used a large database of temporally-resolved plant–pollinator networks to investigate how temporal aggregation from the scale of one day to multiple years influences network structure. In addition, we used structural equation modeling to explore the direct and indirect effects of temporal scale, species richness, species turnover, link rewiring and sampling effort on network structural properties. We find that plant–pollinator network structure is strongly temporally-scale dependent. This general pattern arises because the temporal scale determines the degree to which temporal dynamics (i.e. phenological turnover of species and links) are included in the network, in addition to how much sampling effort is put into constructing the network. Ultimately, the temporal scale-dependence of our plant–pollinator networks appears to be mostly driven by species richness, which increases with sampling effort, and species turnover, which increases with temporal extent. In other words, after accounting for variation in species richness, network structure is increasingly shaped by its underlying temporal dynamics. Our results suggest that considering multiple temporal scales may be necessary to fully appreciate the causes and consequences of interaction network structure.Fil: Schwarz, Benjamin.

Finger creases lend a hand in Kabuki syndrome.

International audienceKabuki syndrome (KS) is a rare syndrome associating malformations with intellectual deficiency and numerous visceral, orthopedic, endocrinological, immune and autoimmune complications. The early establishment of a diagnostic of KS leads to better care of the patients and therefore prevents complications such as perception deafness, severe complications of auto-immune diseases or obesity. However, the diagnosis of KS remains difficult because based on the appreciation of facial features combined with other highly variable features. We describe a novel sign, namely the attenuation and/or congenital absence of the IPD crease of the third and fourth fingers associated with limitation of flexion of the corresponding joints, which seems to be specific of KS and could help the clinician to diagnose KS

Genome of the Asian Longhorned Beetle (\u3cem\u3eAnoplophora glabripennis\u3c/em\u3e), a Globally Significant Invasive Species, Reveals Key Functional and Evolutionary Innovations at the Beetle-Plant Interface

Background: Relatively little is known about the genomic basis and evolution of wood-feeding in beetles. We undertook genome sequencing and annotation, gene expression assays, studies of plant cell wall degrading enzymes, and other functional and comparative studies of the Asian longhorned beetle, Anoplophora glabripennis, a globally significant invasive species capable of inflicting severe feeding damage on many important tree species. Complementary studies of genes encoding enzymes involved in digestion of woody plant tissues or detoxification of plant allelochemicals were undertaken with the genomes of 14 additional insects, including the newly sequenced emerald ash borer and bull-headed dung beetle. Results: The Asian longhorned beetle genome encodes a uniquely diverse arsenal of enzymes that can degrade the main polysaccharide networks in plant cell walls, detoxify plant allelochemicals, and otherwise facilitate feeding on woody plants. It has the metabolic plasticity needed to feed on diverse plant species, contributing to its highly invasive nature. Large expansions of chemosensory genes involved in the reception of pheromones and plant kairomones are consistent with the complexity of chemical cues it uses to find host plants and mates. Conclusions: Amplification and functional divergence of genes associated with specialized feeding on plants, including genes originally obtained via horizontal gene transfer from fungi and bacteria, contributed to the addition, expansion, and enhancement of the metabolic repertoire of the Asian longhorned beetle, certain other phytophagous beetles, and to a lesser degree, other phytophagous insects. Our results thus begin to establish a genomic basis for the evolutionary success of beetles on plants

Egr2 overexpression in Schwann cells increases myelination frequency in vitro

Schwann cells are key players in peripheral nerve regeneration, and are uniquely capable of remyelinating axons in this context. Schwann cells orchestrate this process via a set of transcription factors. While it has been shown that overexpression of specific genes, e.g. Egr2, upregulates myelin-related transcripts, it remains unknown if such manipulation can functionalize the cells and enhance their myelination frequency. The ability to do so could have implications in the use of human stem cell-derived Schwann cells, where myelination is hard to achieve. After screening four candidate transcription factors (Sox10, Oct6, Brn2 and Egr2), we found that overexpression of Egr2 in rat Schwann cells co-cultured with sensory neurons enhanced myelination frequency and reduced cell proliferation. However, in a mouse model of sciatic nerve repair with cells engrafted within a nerve guide, myelination frequency in the engrafted cells was reduced upon Egr2 overexpression. Our results show that while overexpression of Egr2 can enhance the myelination frequency in vitro, it is context-dependent, potentially influenced by the microenvironment, timing of association with axons, expression level, species differences, or other factors

Antioxidant and anti-proliferative properties of Davidson's plum (Davidsonia pruriens F. Muell) phenolic-enriched extracts as affected by different extraction solvents

The Davidson's plum (DP; Davidsonia pruriens F. Muell) is a fruit native to Australia that is a rich source of phenolic compounds. This study investigated the effects of various extraction solvents (ethanol, methanol, acetone and water) on total phenolic content (TPC), antioxidant capacity (ABTS, DPPH, CUPRAC, FRAP assays) and anti-proliferative activity (MTT, CCK-8 assays) of DP. Our data revealed that extraction solvents significantly affected the physico-chemical, antioxidant and anti-proliferative properties of DP extracts. Within the tested solvents, ethanol was found to be the optimal solvent for extraction of bioactive compounds from DP as its extract had the greatest TPC (94.13 GAE/g), flavonoids (78.33 mg RUE/g), proanthocyanidins (5.33 mg CAE/g), anthocyanidins (2.81 mg CGE/g), as well as possessed the highest antioxidant capacity and anti-proliferative activity against a panel of cancer cell lines. This included cancers of the pancreas, breast, lung, brain, skin, colon and ovary. Therefore, further investigations should be conducted to identify key bioactive compounds to determine the potential for utilization in the nutraceutical and phytopharmaceutical industries
