Glassmaking as Scribal Craft
No full textIn the ancient Near East, expert craftspeople were more than technicians: they numbered among those special members of society who could access the divine. While the artisans’ names are largely unknown today, their legacy remains in the form of spectacular artworks and monuments. One of the most celebrated works of antiquity—Babylon’s Ishtar Gate and its affiliated Processional Way—featured a dazzling array of colorful beasts assembled from molded, baked, and glazed bricks. Such an awe-inspiring structure demanded the highest level of craft; each animal was created from dozens of bricks that interlocked like a jigsaw. Yet this display of technical and artistic skill also served a ritual purpose, since the Gate provided a divinely protected entrance to the sacred inner city of Babylon.
A Wonder to Behold explores ancient Near Eastern ideas about the transformative power of materials and craftsmanship as they relate to the Ishtar Gate. This beautifully illustrated catalogue accompanies an exhibition at New York University’s Institute for the Study of the Ancient World. Essays by archaeologists, art historians, curators, conservators, and text specialists examine a wide variety of artifacts from major American and European institutions
Emotional availability (EA) teleintervention for adoptive families
No full text2012 Fall.Includes bibliographical references.This study evaluated the new online Emotional Availability (EA) Intervention for use with adoptive families in enhancing parent-child EA, parental perceptions of EA, child attachment behaviors, parent-child emotional attachment, and reducing parent-reported child behavioral problems and parenting-related stress. Participants in this study were adoptive parents and their adopted children ages 1.5 - 5 years old (N = 15 dyads). Participants were placed in an immediate intervention group (IG) or a delayed intervention group (DG) that would receive the 6-week EA Intervention after the IG. Results revealed significant differences in the IG in child behavioral problems, parent-child EA, parental perceptions of EA, and parent-child emotional attachment, improvements not seen in the DG. Analysis of effects of the DG after receiving the EA Intervention revealed significant differences over time also in child behavioral problems, parent-child EA, parental perceptions of EA, and parent-child emotional attachment. Implications, limitations, and future directions are discussed
Environmental (waste) compliance control systems for UK SMEs
No full textWhile the ‘environment’ is often perceived as a heavily regulated area of business, in reality, directly-regulated businesses represent a small proportion of the business community. This study aimed to evaluate and outline potential improvements to compliance controls for small and medium-sized enterprises (SMEs), particularly those involved in the waste sector. Forty-four SMEs from England were interviewed/audited between April-September 2008. Using a UK-based system as a case-in-point, the Environment Agency’s (EA) Operational Risk Appraisal (‘Opra’)/Compliance Assessment Report (CAR) system was analysed. Environmental compliance performance indicators and an initial assessment methodology for SMEs were developed. The study showed:• Compliance with permitting legislation was poor in many areas.• Regulatory authorities are either unable/failing to implement their enforcement policies or unable/failing to identify non-compliances due to the infrequency or limited nature of their inspections.• Improvements are needed to the EA Opra/CAR system – control measures are not fully taken into account when calculating risk.Recommendations to improve SME compliance controls include using internationally applicable general and specific compliance and non-compliance performance indicators, re-designing the Opra system and using an initial assessment methodology based on understanding the hazardousness of SME categories, compliance levels and operator competency.<br/

Comparative genomic and transcriptomic analysis revealed genetic characteristics related to solvent formation and xylose utilization in <it>Clostridium acetobutylicum </it>EA 2018
No full textAbstract Background Clostridium acetobutylicum, a gram-positive and spore-forming anaerobe, is a major strain for the fermentative production of acetone, butanol and ethanol. But a previously isolated hyper-butanol producing strain C. acetobutylicum EA 2018 does not produce spores and has greater capability of solvent production, especially for butanol, than the type strain C. acetobutylicum ATCC 824. Results Complete genome of C. acetobutylicum EA 2018 was sequenced using Roche 454 pyrosequencing. Genomic comparison with ATCC 824 identified many variations which may contribute to the hyper-butanol producing characteristics in the EA 2018 strain, including a total of 46 deletion sites and 26 insertion sites. In addition, transcriptomic profiling of gene expression in EA 2018 relative to that of ATCC824 revealed expression-level changes of several key genes related to solvent formation. For example, spo0A and adhEII have higher expression level, and most of the acid formation related genes have lower expression level in EA 2018. Interestingly, the results also showed that the variation in CEA_G2622 (CAC2613 in ATCC 824), a putative transcriptional regulator involved in xylose utilization, might accelerate utilization of substrate xylose. Conclusions Comparative analysis of C. acetobutylicum hyper-butanol producing strain EA 2018 and type strain ATCC 824 at both genomic and transcriptomic levels, for the first time, provides molecular-level understanding of non-sporulation, higher solvent production and enhanced xylose utilization in the mutant EA 2018. The information could be valuable for further genetic modification of C. acetobutylicum for more effective butanol production.</p
