Influence of Process Parameters on Chlorinated Biocide Decontamination by li-CO2 on Artificially Contaminated Model Materials     

Tiziana Lombardo  Marie Wörle  Vera Hubert  Erwin Hildbrand  Christina Hinterleitner  Ingo Mayer 《文物保护研究》2020,65(2):65-76

ABSTRACT

Previously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO₂ was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO₂ decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present.  相似文献   

Great Expectations? Childhood,Family, and Middle-Class Social Mobility in Nineteenth-Century England     

Christina De Bellaigue 《Cultural and Social History》2019,16(1):29-46

ABSTRACT

Existing histories of social mobility have focused on adults and on measuring the achievement of individual upward mobility. However, children and families were central to mobility strategies. Using the papers of the Heywoods of Bolton, this article examines how the families of the industrial middle class endowed their offspring with the goods and character needed to secure their social standing, highlighting the emotional intricacy of these processes. It demonstrates that such families conceived of social mobility as a familial project and that rather than pursuing upward mobility, their chief objective was to guard against social decline.  相似文献   

Using Prompt Fading to Teach Self‐Questioning to Fifth Graders with LD: Effects on Reading Comprehension     

Christina A. Rouse  Sheila R. Alber‐Morgan  Jennifer M. Cullen  Mary Sawyer 《Learning disabilities research & practice》2014,29(3):117-125

Students with LD who struggle with reading comprehension can benefit from instruction on how to read strategically. One strategy that has been demonstrated to increase reading comprehension is self‐questioning. In this study, two fifth graders with LD were taught to self‐generate questions using a prompt fading procedure. The participants were provided with expository reading passages with embedded questions. As each participant demonstrated proficiency with answering the embedded questions correctly, the embedded questions were systematically faded and replaced with a prompt for the students to generate their own questions. A multiple baseline across participants design demonstrated that the self‐questioning intervention resulted in improvements in reading comprehension for both students. Additionally, the students demonstrated evidence of maintenance and generalization of reading comprehension outcomes.  相似文献   

The Greek Publishing Industry and Professional Development     

Christina Banou  Angus Phillips 《Publishing Research Quarterly》2008,24(2):98-110

In the Greek publishing industry, tradition and the desire for innovation go hand in hand. The industry is influenced by European developments in publishing and bookselling in terms of book promotion methods, the role of chain bookstores and the impact of information technology. Greece shares the features of other small book markets in Europe, whilst retaining the individuality defined by the Greek language and the country’s cultural and social conditions. This article provides an overview of the publishing industry in Greece through a review of the relevant literature and the available statistics. This work also focuses on the need to develop publishing skills through publishing education and continuous professional development.  相似文献

A biographical narrative inquiry into teachers’ knowledge: an intergenerational approach     

Hong qin Zhao  Louise Poulson 《Asia Pacific Education Review》2006,7(2):123-132

This study is an investigation into Chinese EFL teachers’ knowledge and understanding of teaching English as a foreign language within the context of a time of tremendous social change in China. In a medium-sized city, biographical narrative interviews and observation were used to three Chinese secondary EFL teachers, of three successive generations. An in-depth narrative analysis interpreting their metaphors, and constructing their life stories is employed to understand the biographical narrative data. It indicates how individual teacher’s knowledge is both constrained and enabled by themselves and by the wider society they live in, and how change and continuity are intertwined in the teaching and learning practices of the three generations. This paper also addresses certain key issues in biographical narrative studies, namely subjectivity, representation, and cultural bearings, and teachers’ knowledge, all of which constitute a form of pedagogy in educational research.  相似文献   

Chemical bleaching of wood: an investigation into the bleaching of mahogany,walnut, rosewood,padauk, and purpleheart     

Louise Herstedt  Marie Herstedt 《文物保护研究》2017,62(3):162-172

This paper investigates chemical bleaching of wood to make species-specific practical recommendations for colour adjustment of veneer in furniture conservation. In more detail, chemical bleaching of Honduras mahogany (Swietenia macrophylla), European walnut (Juglans regia), Rio rosewood (Dalbergia nigra), padauk (Pterocarpus spp.), and purpleheart (Peltogyne spp.) is investigated using 11 different bleach solutions. Both oxidative (e.g. hydrogen peroxide and potassium permanganate) and reductive (e.g. oxalic acid and sodium bisulphite) solutions were used. The results show that the wood species react differently with the investigated bleach solutions. It can also be noted that not all investigated solutions were suitable for all wood species. Based on the results, wood species-specific bleach solutions are recommended.  相似文献   

Sales Forecasting of New Entertainment Media Products     

Christina Hofmann-Stölting  Steven Wu  Sönke Albers 《Journal of Media Economics》2017,30(3):143-171

Managers predict the sales of new entertainment products prior to their release using comparables, such as similar books from the same author or movies with the same actors. In this study, the authors analyze whether diffusion models for media products provide helpful support in the management task of predicting prelaunch sales of the first distribution channel for three different product categories. They compare the performance of predictions based on (a) simple success factor regressions (OLS) and (b) diffusion models against real management predictions. Based on samples covering the German music, film, and the literary market, we show that model-based forecasts outperform the forecasts of management teams for the majority of the products. In contrast, management is superior in forecasting top sellers. This is due to unobserved factors arising from more management attention attached towards super stars. The authors do not find substantial prediction differences between simple success factor regressions and more complex diffusion models. Thus, managers interested in total sales estimates can easily rely on OLS based success factor predictions. Advertising and product differentiation factors with respect to quality (e.g., star power, critics, or country of origin) are across all 3 industries highly relevant for sales predictions, whereas others variables (e.g., price, distribution power, season, or competition) differ across industries.  相似文献
