The Transmission of Marital Instability across Generations: Relationship Skills or Commitment to Marriage?

Abstract: We used national, longitudinal data from 2 generations to assess 2 explanations for the intergenerational transmission of marital instability, one based on relationship skills and the other based on marital commitment. Parental divorce approximately doubled the odds that offspring would see their own marriages end in divorce. Offspring with maritally distressed parents who remained continuously married did not have an elevated risk of divorce. Divorce was most likely to be transmitted across generations if parents reported a low, rather than a high, level of discord prior to marital dissolution. These results, combined with other findings from the study, suggest that offspring with divorced parents have an elevated risk of seeing their own marriages end in divorce because they hold a comparatively weak commitment to the norm of lifelong marriage.

Contemporary issues in thermal gasification of biomass and its application to electricity and fuel production.

Abstract: Gasification technology has been investigated to effectively and economically convert low-value and highly distributed solid biomass to a uniform gaseous mixture mainly including hydrogen (H 2 ), carbon monoxide (CO), methane (CH 4 ) and carbon dioxide (CO 2 ). This gaseous mixture can be further used as an industrial feedstock for heat and power generation, H 2 production and synthesis of liquid fuels. Significant advances have been made in the technology of biomass gasification and syngas utilization. This review was conducted to introduce the recent advances in biomass gasification and syngas utilization. The critical technical issues and perspectives of biomass gasification were discussed.

A prototype document image analysis system for technical journals

Abstract: Gobbledoc, a system providing remote access to stored documents, which is based on syntactic document analysis and optical character recognition (OCR), is discussed. In Gobbledoc, image processing, document analysis, and OCR operations take place in batch mode when the documents are acquired. The document image acquisition process and the knowledge base that must be entered into the system to process a family of page images are described. The process by which the X-Y tree data structure converts a 2-D page-segmentation problem into a series of 1-D string-parsing problems that can be tackled using conventional compiler tools is also described. Syntactic analysis is used in Gobbledoc to divide each page into labeled rectangular blocks. Blocks labeled text are converted by OCR to obtain a secondary (ASCII) document representation. Since such symbolic files are better suited for computerized search than for human access to the document content and because too many visual layout clues are lost in the OCR process (including some special characters), Gobbledoc preserves the original block images for human browsing. Storage, networking, and display issues specific to document images are also discussed. >

Fermentation of fructooligosaccharides by lactic acid bacteria and bifidobacteria.

Abstract: Lactic acid bacteria and bifidobacteria were screened of their ability to ferment fructooligosaccharides (FOS) on MRS agar. Of 28 strains of lactic acid bacteria and bifidobacteria examined, 12 of 16 Lactobacillus strains and 7 of 8 Bifidobacterium strains fermented FOS. Only strains that gave a positive reaction by the agar method reached high cell densities in broth containing FOS.

Tropical climate changes at millennial and orbital timescales on the Bolivian Altiplano

Abstract: Tropical South America is one of the three main centres of the global, zonal overturning circulation of the equatorial atmosphere (generally termed the ‘Walker’ circulation1) Although this area plays a key role in global climate cycles, little is known about South American climate history Here we describe sediment cores and down-hole logging results of deep drilling in the Salar de Uyuni, on the Bolivian Altiplano, located in the tropical Andes We demonstrate that during the past 50,000 years the Altiplano underwent important changes in effective moisture at both orbital (20,000-year) and millennial timescales Long-duration wet periods, such as the Last Glacial Maximum—marked in the drill core by continuous deposition of lacustrine sediments—appear to have occurred in phase with summer insolation maxima produced by the Earth's precessional cycle Short-duration, millennial events correlate well with North Atlantic cold events, including Heinrich events 1 and 2, as well as the Younger Dryas episode At both millennial and orbital timescales, cold sea surface temperatures in the high-latitude North Atlantic were coeval with wet conditions in tropical South America, suggesting a common forcing
