Abstract

A recent survey of 1,948 retail stores in India conducted by the World Bank's Enterprise surveys shows that 19 per cent of all stores use computers. In the state of Kerala, the figure is as high as 40 per cent. Using this survey, we estimate the effect of computer usage on labour employment. Our findings show that this effect depends on the stringency of the underlying labour laws. Stricter labour laws magnify the labour displacing effect of computers significantly.  相似文献

The European Commission's claim that their proposed new telecoms regulation2 constitutes “the most ambitious plan in 26 years of telecoms market reform” is preposterous. That honour must belong to the set of new European directives in 2002 which transformed the structure of telecoms regulation and facilitated competition throughout Europe. Instead the plans make great play of a number of actually pretty minor changes and, the Body for European Regulators for Electronic Communications (“BEREC”) has been particularly critical that the proposals will create unnecessary complexity and uncertainty and limit innovation and competition.  相似文献

<正>British-American historian Bernard Lewis famously condemned Arab and Islamic civilization for not having a polyphonic sense of music,even accusing them of accepting totalitarian ideologies and regimes because of their taste for"monophonic"music.That is,having one single singer with all the music following the ups and downs of his or her voice.Polyphonic music,by contrast,is when a piece of music has two or more independent melodies in it.As for the related notion of counterpoint,this is from many voices present in the chorus of a classical Greek drama and a reference to the coordination evident in choir singing.  相似文献

The PowerPlex 16 BIO multiplex short tandem repeat (STR) system contains the 13 CODIS loci (FGA, TPOX, D8S1179, vWA, D18S51, D21S11, TH01, D3S1358, CSF1PO, D16S539, D7S820, D13S317, and DS5S818), plus two pentanucleotide repeat loci (Penta D and Penta E) and the sex-identifying locus. Amelogenin. The PowerPlex 16 BIO System is optimized for use with the Hitachi FMBIO gel imaging systems. A consortium of seven independent laboratories collaborated to perform the studies defined by the FBI standards for performing a developmental validation, including the evaluation of sample concordance, percent stutter determination, nonprobative casework, precision, sensitivity, mixture determination, effect of substrates, the impact of environmental insults, and species specificity. All samples tested for concordance were consistent except for one sample from the Virginia Division of Forensic Science database that displayed discordance at D13S317, a locus whose primer sequence was altered. Stutter values were comparable to those of other STR multiplex systems, the precision was comparable to other multiplexes analyzed by gel electrophoresis, the DNA profiles were unchanged by the substrate upon which the blood samples were placed, and the nonprobative casework samples re-typed for the PowerPlex 16 BIO System were consistent with previous typing results. When greater than 0.125 ng of DNA was placed into the PowerPlex 16 BIO System amplification reaction, a full profile was generated by all laboratories. The mixture study results were comparable to those reported for other multiplex systems, the environmental study demonstrated a loss of larger molecular weight loci when samples were incubated at elevated temperatures for a prolonged period of time, and the only notable cross species hybridization was observed with primate DNA samples. This extensive validation work performed demonstrates that the PowerPlex 16 BIO System provides STR data of a quality comparable with other PowerPlex STR multiplex kits as well as other widely used STR multiplexes and is thus suitable for evidentiary casework analysis as well as database sample profiling.  相似文献

At first glance, my motherland, Egypt, and China seem to be worlds apart. In a strictly geographical sense, there are 6,896 km between them. But a closer look reveals much the two countries have in common. That was what my uncle, who served as ambassador to China in the 1990s, used to tell me.  相似文献

This article deals with the issue of honour killings, a particular type of intrafamily femicide in defence of honour in Jordan. The legal, social, religious, nationalist and tribal dimensions and arguments on such killings are presented. Drawing on Arabic and English source material the role of rumour, social values and other dynamics in normalising this practice in Jordan today is analysed. Honour killings, which contradict many international and national laws and covenants, are clearly connected to the subordination of women in Jordan and to the 'criming down' of domestic violence. The prevailing discriminatory culture cannot change without implementing a comprehensive programme for socio-legal and political reform.  相似文献

Recent studies suggest that consumer-household attributes may be as important in determining the level of competition in certain markets as firm characteristics and the number of firms. However, evidence on which consumer-household attributes matter for competition is limited, especially for developing countries. Focusing on India's retail sector, this article contributes to this literature by showing that the number of adult non-workers per household in the city, a proxy for shopping time opportunity cost, has a strong effect on competition between retailers. Policy implications of our findings in light of the ongoing dramatic reductions in non-workers in India are discussed.  相似文献
