Over the twentieth century, the allocation of womens' time changed dramatically. This paper explores the implications for the allocation of married womens' time stemming from: (1) the household revolution associated with the introduction of a variety of labor-saving devices in the home; (2) the remarkable increase in the relative wage of women; and (3) changes in childcare requirements associated with changes in fertility patterns. To do so, we construct a life-cycle model with home production and childcare constraints. The parameters of the childcare production function are estimated using micro evidence from U.S. time use data. We find that the increase in the relative wage of women is the most important explanation of the increase in married womens' market work time over the twentieth century. Changes in fertility had large effects up to 1980, but little effect thereafter. The declining price of durables has an appreciable effect only since 1980, an effect that is consistent with a broader interpretation of durable goods reflecting the marketization of home production.

One thousand, two hundred and sixty four samples of individually quick-frozen (IQF) peeled and deveined raw and 914 samples of cooked ready to eat shrimp samples produced from farm raised black tiger (Penaeus monodon) obtained from a seafood unit working under HACCP concept were analysed for total aerobic plate count (APC), coliform count, Escherichia coli, coagulase positive Staphylococci and Salmonella. The overall bacteriological quality of the product was found to be good. Of the frozen raw shrimp, 96% of samples showed APC below 105 while 99% of the frozen cooked ready-to-eat samples showed APC less than 104. The APC ranged from 1·0´102 to 4·2´106 cfu/gm in frozen raw shrimp and from 1·0´102 to 6·4´104 cfu/gm in the frozen cooked shrimp. Prevalences of coliforms in raw shrimp and cooked shrimp samples were 14·4% and 2·9% respectively. The coliform count in raw products ranged from 1·0´101 to 2·5´103 cfu/gm and in the cooked products, from 1·0 ´101 to 1·8´102 cfu/gm. Although all the cooked shrimp samples were free of coagulase positive staphylococci, E. coli and Salmonella, 1·0, 2·0 and 0·1% of the frozen raw shrimp samples tested positive for coagulase positive Staphylococci, E. coli and Salmonella respectively. The Salmonella strain was identified as Salmonella typhimurium. The results of the present study highlight the importance of implementation of HACCP system in the seafood industry to ensure consistent quality of frozen seafood

Tuesday 22nd April 2014 Speaker(s): Sue Sentance Organiser: Leslie Carr Time: 22/04/2014 15:00-16:00 Location: B32/3077 File size: 698 Mb Abstract Until recently, "computing" education in English schools mainly focused on developing general Digital Literacy and Microsoft Office skills. As of this September, a new curriculum comes into effect that provides a strong emphasis on computation and programming. This change has generated some controversy in the news media (4-year-olds being forced to learn coding! boss of the government’s coding education initiative cannot code shock horror!!!!) and also some concern in the teaching profession (how can we possibly teach programming when none of the teachers know how to program)? Dr Sue Sentance will explain the work of Computing At School, a part of the BCS Academy, in galvanising universities to help teachers learn programming and other computing skills. Come along and find out about the new English Computing Revolution - How will your children and your schools be affected? - How will our University intake change? How will our degrees have to change? - What is happening to the national perception of Computer Science?

La evolución explica cómo llegamos a existir. Más de ciento cincuenta años más tarde de las teorías de Darwin, sus ideas se han hecho más convincentes, aunque siguen siendo controvertidas en algunas partes del mundo. Este conocimiento nos ayuda a comprender la enfermedad y la salud, nuestros instintos, emociones y, por encima de todo, a reconocer lo próximos que estamos de otros organismos vivos.
