Abstract

This article questions two widely accepted claims on long-term food insecurity in Asia, the world's (heterogeneous) region with the largest number of undernourished individuals. The first claim is that food production may not grow as fast as the pace of population growth in Asia, which will reach 5 billion by 2050. The second claim is that an unstoppable emergence of a middle class in Asia will dramatically change the composition of food demand. On the first claim, the region's contribution to high and volatile international food prices is well known, but Asia's potentially positive contributions toward future price uncertainty and productivity growth are much less cited. On the second claim, the changing composition of future food demand in the region will depend on the extent that poverty reduction effectively leads to middle class expansion, which it is not an automatic process, and its extent still remains to be seen. Past evidence teaches us that poverty reduction on its own will not do the job of eradicating hunger, nor will only increasing food production. The jury is still out, but doomsday predictions are not necessarily justified.  相似文献

This paper maintains that although there is much interest at the moment in exploring the Ethical, Legal and Social Implications (ELSI) of nanotechnology, the ability to do so in a critical and reflective way, in part, depends on how nanotechnology's future is envisioned. It is argued that, at present, this vision is articulated through the novum, a narrative device borrowed from the science fiction (SF) genre. The paper concludes by arguing that the widely shared narratives about nanotechnology's future, structured by the novum, not only limit the types of ELSI questions that can be addressed but also lead to a polarized debate. It is also suggested that the device of the novum also obscures the heterogeneous nature of nanotechnology itself.  相似文献

We report here a review of the seventh mitochondrial DNA (mtDNA) exercise undertaken by the Spanish and Portuguese working group (GEP) of the International Society for Forensic Genetics (ISFG) corresponding to the period 2003-2004. Five reference bloodstains from five donors (M1-M5), a mixed stain of saliva and semen (M6), and a hair sample (M7) were submitted to each participating laboratory for nuclear DNA (nDNA; autosomal STR and Y-STR) and mtDNA analysis. Laboratories were asked to investigate the contributors of samples M6 and M7 among the reference donors (M1-M5). A total of 34 laboratories reported total or partial mtDNA sequence data from both, the reference bloodstains (M1-M5) and the hair sample (M7) concluding a match between mtDNA profiles of M5 and M7. Autosomal STR and Y-STR profiling was the preferred strategy to investigate the contributors of the semen/saliva mixture (M6). Nuclear DNA profiles were consistent with a mixture of saliva from the donor (female) of M4 and semen from donor M5, being the semen (XY) profile the dominant component of the mixture. Strikingly, and in contradiction to the nuclear DNA analysis, mtDNA sequencing results yield a more simple result: only the saliva contribution (M4) was detected, either after preferential lysis or after complete DNA digestion. Some labs provided with several explanations for this finding and carried out additional experiments to explain this apparent contradictory result. The results pointed to the existence of different relative amounts of nuclear and mtDNAs in saliva and semen. We conclude that this circumstance could strongly influence the interpretation of the mtDNA evidence in unbalanced mixtures and in consequence lead to false exclusions. During the GEP-ISFG annual conference a validation study was planned to progress in the interpretation of mtDNA from different mixtures.  相似文献

Allele and haplotype frequencies for nine Y-specific STR loci (DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS393, DYS434, DYS437, and DYS439) were obtained from a sample of 57 males from Guinea Equatorial.  相似文献

The recent disastrous financial performance of the airline industry is probably thought by many to indicate that deregulation is not workable. But simulations suggest that the current recession and the 1979 fuel price increase are primarily to blame. Deregulation has caused transitional losses for some segments of the industry; but the new freedoms accorded to the airlines probably have helped rather than hurt the profitability of the industry.  相似文献

Haplotype frequencies of eight Y-chromosome STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393 and DYS385) were determined from a sample of 285 unrelated males from Canary Islands.  相似文献

The present study provides a cross-national comparison of parental models of family violence as predictors of romantic partner violence reported by college women. Participants included college women from the United States (n?=?319), Spain (n?=?95), and Turkey (n?=?207) to report violence in five relationships: father-to-mother, mother-to-father, father-to-participant, mother-to-participant, and romantic-partner-to-participant. Multiple regression revealed that partner violence received by college women was best explained by mother-to-father violence for the United States sample, but by father-to-mother violence for the Spanish and Turkish samples. Results may be useful for college women to identify family and cultural risk factors for romantic partner violence so that they may work to protect themselves and their educational opportunities.  相似文献

This study applies Raman microspectroscopy to differentiate the chemical components in printing inks of different brands, colors, and type using the 532 nm and 785 nm excitation wavelengths. Spectra were collected from 319 inks (78 inkjet, 76 toner, 79 offset, and 86 intaglio) representing various colors. Comparisons were performed to calculate discrimination capability percentages for each ink type. Overall, Raman microspectroscopy differentiates according to the following hierarchy: intaglio (96%), inkjet (92%), offset (90%), and toner (61%). The ability of Raman microspectroscopy to differentiate between same‐colored inks from different brands was dependent on the color and ink analyzed. Based on ink color, the discrimination capability ranged from 75 to 94% (inkjet), 0 to 86% (toner), and 0 to 77% (offset). Copper phthalocyanine was detected in cyan inks and various intaglio inks, while carbon black was identified in black inkjet, offset, and intaglio inks.  相似文献

Path analysis was used to assess the contribution of four exogenous developmental variables (sexual abuse, physical abuse, exposure to violence, exposure to pornography—each occurring prior to age 13) and four personality constructs (“psychopathic and antagonistic attitudes,” “psychosocial deficits,” “pedophilia,” “hostile masculinity”) to the prediction of non-sexual delinquency and number of male child victims in a sample of 256 adolescent males with a history of “hands-on” sexual offending. “Psychosocial deficits” was found to partially mediate the effects of the exogenous variables on both outcomes. Exposure to violence both directly, and indirectly through “psychopathic and antagonistic attitudes,” contributed to the prediction of non-sexual delinquency. Sexual abuse by a male directly, and indirectly through “hostile masculinity” and “pedophila”, contributed to prediction of number of male child victims. Clinical implications of the findings are discussed.  相似文献
