Museum Approaches to Judaica: The Forgotten Spoils of the Nazi Plunder of Europe

Museum professionals are faced with many legal and ethical issues on a daily basis, many of which are rooted in the actions of people in the past. One of the largest issues discussed in our community over the last several decades stems from the mass looting of artwork across Europe by the Nazis during World War Two. While much attention has been given to the procedures and practices museums must go through in order to identify potential stolen works and return them to their rightful owners, Jewish homes, businesses, and synagogues were also ransacked by German soldiers and anything of perceived value was stolen. Countless works of Judaica, or Jewish ceremonial objects, and sacred texts were taken from communities and families alike. What has happened with these objects after that fall of the Third Reich, especially when the majority of the Jewish population that once owned these items never returned? My thesis examines the underrepresented topic of looted Judaica from World War Two, particularly looking at its role in museum collections. I examine the actions taken after the war to redistribute heirless property to Jewish museums and institutions around the world and the ongoing international efforts and discussions on provenance research and restitution of these objects as new Jewish communities are forming across Europe. I also examine the issue of object care for looted Judaica from the Registrar’s or Collection Manager’s perspective, identifying special requirements for these objects under Jewish law. Through a series of three case studies, I explore the actual implementation of restitution and special care procedures in Jewish museum today in order to determine the current state of the field. Ultimately, I argue that Jewish institutions need to devote more time to developing restitution claim procedures and policies, while also reshaping their collection care guidelines to reflect, not only museum best practices, but also respect to Jewish tradition and law

Children’s whining in family interaction

Children’s whining is identified in extracts of video-recorded social interaction at home with siblings, parents and other family. “Whining” is primarily a vernacular category, but can be identified in terms of a set of phonetic features including pitch movement, loudness and nasality, and contrasted with crying. We focus on the uses and consequences of whining, in and for social interaction. Rather than identifying and attributing experiential causes or correlates of whining, we examine what children do with it, how it is occasioned, and how others, mostly parents, respond to it. Whining performs actions such as objecting to transgressions and thwarted goals, and making complaints. Parental reactions include one or more of: “stance inversion,” which is the adoption of a contrasting tone in next turn; formulations of the offending circumstances; orientations to remedying the problem; and rejection of the whine’s basis, including dispositional formulations of the child’s whining (e.g., being “grumpy”), and accounts for not complying with a called-for remedy.

Evolution from a respiratory ancestor to fill syntrophic and fermentative niches: comparative fenomics of six Geobacteraceae species

<p>Abstract</p> <p>Background</p> <p>The anaerobic degradation of organic matter in natural environments, and the biotechnical use of anaerobes in energy production and remediation of subsurface environments, both require the cooperative activity of a diversity of microorganisms in different metabolic niches. The <it>Geobacteraceae </it>family contains members with three important anaerobic metabolisms: fermentation, syntrophic degradation of fermentation intermediates, and anaerobic respiration.</p> <p>Results</p> <p>In order to learn more about the evolution of anaerobic microbial communities, the genome sequences of six <it>Geobacteraceae </it>species were analyzed. The results indicate that the last common <it>Geobacteraceae </it>ancestor contained sufficient genes for anaerobic respiration, completely oxidizing organic compounds with the reduction of external electron acceptors, features that are still retained in modern <it>Geobacter </it>and <it>Desulfuromonas </it>species. Evolution of specialization for fermentative growth arose twice, via distinct lateral gene transfer events, in <it>Pelobacter carbinolicus </it>and <it>Pelobacter propionicus</it>. Furthermore, <it>P. carbinolicus </it>gained hydrogenase genes and genes for ferredoxin reduction that appear to permit syntrophic growth via hydrogen production. The gain of new physiological capabilities in the <it>Pelobacter </it>species were accompanied by the loss of several key genes necessary for the complete oxidation of organic compounds and the genes for the <it>c</it>-type cytochromes required for extracellular electron transfer.</p> <p>Conclusion</p> <p>The results suggest that <it>Pelobacter </it>species evolved parallel strategies to enhance their ability to compete in environments in which electron acceptors for anaerobic respiration were limiting. More generally, these results demonstrate how relatively few gene changes can dramatically transform metabolic capabilities and expand the range of environments in which microorganisms can compete.</p

Evolution of electron transfer out of the cell: comparative genomics of six Geobacter genomes

Background: Geobacter species grow by transferring electrons out of the cell - either to Fe(III)-oxides or to manmade substances like energy-harvesting electrodes. Study of Geobacter sulfurreducens has shown that TCA cycle enzymes, inner-membrane respiratory enzymes, and periplasmic and outer-membrane cytochromes are required. Here we present comparative analysis of six Geobacter genomes, including species from the clade that predominates in the subsurface. Conservation of proteins across the genomes was determined to better understand the evolution of Geobacter species and to create a metabolic model applicable to subsurface environments. Results: The results showed that enzymes for acetate transport and oxidation, and for proton transport across the inner membrane were well conserved. An NADH dehydrogenase, the ATP synthase, and several TCA cycle enzymes were among the best conserved in the genomes. However, most of the cytochromes required for Fe(III)-reduction were not, including many of the outer-membrane cytochromes. While conservation of cytochromes was poor, an abundance and diversity of cytochromes were found in every genome, with duplications apparent in several species. Conclusions: These results indicate there is a common pathway for acetate oxidation and energy generation across the family and in the last common ancestor. They also suggest that while cytochromes are important for extracellular electron transport, the path of electrons across the periplasm and outer membrane is variable. This combination of abundant cytochromes with weak sequence conservation suggests they may not be specific terminal reductases, but rather may be important in their heme-bearing capacity, as sinks for electrons between the inner-membrane electron transport chain and the extracellular acceptor

Genomic and microarray analysis of aromatics degradation in Geobacter metallireducens and comparison to a Geobacter isolate from a contaminated field site

<p>Abstract</p> <p>Background</p> <p>Groundwater and subsurface environments contaminated with aromatic compounds can be remediated <it>in situ </it>by <it>Geobacter </it>species that couple oxidation of these compounds to reduction of Fe(III)-oxides. <it>Geobacter metallireducens </it>metabolizes many aromatic compounds, but the enzymes involved are not well known.</p> <p>Results</p> <p>The complete <it>G. metallireducens </it>genome contained a 300 kb island predicted to encode enzymes for the degradation of phenol, <it>p</it>-cresol, 4-hydroxybenzaldehyde, 4-hydroxybenzoate, benzyl alcohol, benzaldehyde, and benzoate. Toluene degradation genes were encoded in a separate region. None of these genes was found in closely related species that cannot degrade aromatic compounds. Abundant transposons and phage-like genes in the island suggest mobility, but nucleotide composition and lack of synteny with other species do not suggest a recent transfer. The inferred degradation pathways are similar to those in species that anaerobically oxidize aromatic compounds with nitrate as an electron acceptor. In these pathways the aromatic compounds are converted to benzoyl-CoA and then to 3-hydroxypimelyl-CoA. However, in <it>G. metallireducens </it>there were no genes for the energetically-expensive dearomatizing enzyme. Whole-genome changes in transcript levels were identified in cells oxidizing benzoate. These supported the predicted pathway, identified induced fatty-acid oxidation genes, and identified an apparent shift in the TCA cycle to a putative ATP-yielding succinyl-CoA synthase. Paralogs to several genes in the pathway were also induced, as were several putative molybdo-proteins. Comparison of the aromatics degradation pathway genes to the genome of an isolate from a contaminated field site showed very similar content, and suggested this strain degrades many of the same compounds. This strain also lacked a classical dearomatizing enzyme, but contained two copies of an eight-gene cluster encoding redox proteins that was 30-fold induced during benzoate oxidation.</p> <p>Conclusion</p> <p><it>G. metallireducens </it>appears to convert aromatic compounds to benzoyl-CoA, then to acetyl-CoA via fatty acid oxidation, and then to carbon dioxide via the TCA cycle. The enzyme responsible for dearomatizing the aromatic ring may be novel, and energetic investments at this step may be offset by a change in succinate metabolism. Analysis of a field isolate suggests that the pathways inferred for <it>G. metallireducens </it>may be applicable to modeling <it>in situ </it>bioremediation.</p

There are two gas stations, a Family Dollar, a liquor store, a few sit down restaurants, numerous places where one can get a quick bite to eat, a frame shop, a clothing store, a pawn shop, a store with fresh produce (which is hard to find in urban areas), a store that sells sports uniforms, a frame shop, a lawyerʼs office, an animal hospital, two Laundromats, a record shop, a health food store, two cell phone stores, an automotive shop, and a karate school with an afterschool program. With such variety, it will draw people to the area and then give them other reasons to keep coming back

De Novo Assembly of the Complete Genome of an Enhanced Electricity-Producing Variant of Geobacter sulfurreducens Using Only Short Reads

State-of-the-art DNA sequencing technologies are transforming the life sciences due to their ability to generate nucleotide sequence information with a speed and quantity that is unapproachable with traditional Sanger sequencing. Genome sequencing is a principal application of this technology, where the ultimate goal is the full and complete sequence of the organism of interest. Due to the nature of the raw data produced by these technologies, a full genomic sequence attained without the aid of Sanger sequencing has yet to be demonstrated

High-throughput analysis reveals novel maternal germline RNAs crucial for primordial germ cell preservation and proper migration

During oogenesis, hundreds of maternal RNAs are selectively localized to the animal or vegetal pole, including determinants of somatic and germline fates. Although microarray analysis has identified localized determinants, it is not comprehensive and is limited to known transcripts. Here, we utilized high-throughput RNA sequencing analysis to comprehensively interrogate animal and vegetal pole RNAs in the fully grown Xenopus laevis oocyte. We identified 411 (198 annotated) and 27 (15 annotated) enriched mRNAs at the vegetal and animal pole, respectively. Ninety were novel mRNAs over 4-fold enriched at the vegetal pole and six were over 10-fold enriched at the animal pole. Unlike mRNAs, microRNAs were not asymmetrically distributed. Whole-mount in situ hybridization confirmed that all 17 selected mRNAs were localized. Biological function and network analysis of vegetally enriched transcripts identified protein-modifying enzymes, receptors, ligands, RNA-binding proteins, transcription factors and co-factors with five defining hubs linking 47 genes in a network. Initial functional studies of maternal vegetally localized mRNAs show that sox7 plays a novel and important role in primordial germ cell (PGC) development and that ephrinB1 (efnb1) is required for proper PGC migration. We propose potential pathways operating at the vegetal pole that highlight where future investigations might be most fruitful.Fil: Owens, Dawn A..
