Selling Women on PDAs from “Simply Palm” to “Audrey”: How Moore's Law Met Parkinson's Law in the Kitchen

This essay investigates key moments in the history of personal digital assistant (PDA) marketing to women. Analyzing promotional texts for three PDAs that received considerable press coverage from 1999 to 2001, this essay explores the cultural significance of the convergence of anxieties about women's place in the gendered division of labor with the computer industry's changing marketing imperatives. Drawing on an array of promotional texts, including news articles, press releases, promotional Web sites, and ads appearing in newspapers and magazines, this paper tells the story of how the computer industry aimed to sell smaller, faster computing devices to women while promising to mediate and thus reproduce women's overwork as paid and familial laborers. After experimenting with the PDA as a sexy fashionable gadget for working women, marketers approached women as mothers with “Audrey,” an Internet appliance designed for the kitchen.

Enzymatic preparation of manno-oligosaccharides from locust bean gum and palm kernel cake,and investigations into its prebiotic activity

BackgroundManno-oligosaccharides (MOS) is known as a kind of prebiotics. Mannanase plays a key role for the degradation of mannan to produce MOS. In this study, the mannanases of glycoside hydrolase (GH) families 5 Man5HJ14 and GH26 ManAJB13 were employed to prepare MOS from locust bean gum (LBG) and palm kernel cake (PKC). The prebiotic activity and utilization of MOS were assessed in vitro using the probiotic Lactobacillus plantarum strain.ResultsGalactomannan from LBG was converted to MOS ranging in size from mannose up to mannoheptose by Man5HJ14 and ManAJB13. Mannoheptose was got from the hydrolysates produced by Man5HJ14, which mannohexaose was obtained from LBG hydrolyzed by ManAJB13. However, the same components of MOS ranging in size from mannose up to mannotetrose were observed between PKC hydrolyzed by the mannanases mentioned above. MOS stability was not affected by high-temperature and high-pressure condition at their natural pH. Based on in vitro growth study, all MOS from LBG and PKC was effective in promoting the growth of L. plantarum CICC 24202, with the strain preferring to use mannose to mannotriose, rather than above mannotetrose.ConclusionsThe effect of mannanases and mannan difference on MOS composition was studied. All of MOS hydrolysates showed the stability in adversity condition and prebiotic activity of L. plantarum, which would have potential application in the biotechnological applications.How to cite: Zhang R, Li X-Y, Cen X-L, et al.

Locus of control, persistence, and use of contingency information in physically abused children

Abused children are believed to develop in a harsh environment with minimal contingency of parental responses to their behavior. Seligman proposed that noncontingent caregiving produces helplessness. In this study, helplessness was assessed by measures of persistence and locus of control and by an experimental manipulation which varied contingency feedback. Compared to matched nonabused peers, abused children showed no less persistence in working for rewards, made equivalent use of contingency information to maintain persistence, and assumed equivalent responsibility for success. However, they took less responsibility for failure. Family learning history may render abused children helpless primarily in avoidance of aversive outcomes.
