Telephone surveys have been a principle means of learning about the attitudes and behaviors of citizens and voters. The single
mode telephone survey, however, is increasingly threatened by rising costs, the declining use of landline telephones, and
declining participation rates. One solution to these problems has been the introduction of mixed-mode surveys. However, such
designs are relatively new and questions about their representativeness and the intricacies of the methodology remain. We
report on the representativeness of a post election mixed-mode (Internet and mail) survey design of 2006 general election
voters. We compare sample respondent means to sample frame means on key demographic characteristics and examine how mail and
Internet respondents differed in terms of attitudes, behaviors and demographics. We find that overall the Internet respondents
were representative of the population and that respondent choice of mode did not influence item response. We conclude that
mixed-mode designs may allow researchers to ask important questions about political behavior from their desktops. 相似文献

Little is known about the labour market impact of immigration to developing countries, because most immigration to developing countries is poorly measured. We use an unusual dataset from a campaign to register irregular migrants to study how immigration has affected wages, employment, and internal migration in Thailand. We allow for endogenous migration, whereby immigrants are disproportionately attracted to areas with higher wages. Our results suggest that immigration sufficient to increase Thailand's total labour force by one per cent would reduce Thai wages by approximately half a per cent. This effect is stronger than is generally found in developed countries. We find no evidence that immigration has reduced Thai employment rates or has affected internal migration by Thais. 相似文献

AbstractWhen I began teaching in the fall of 1971 at a small liberal arts college, I was greeted by a team-taught, one-semester introductory history course, two-thirds of which outlined the past few centuries of European history. As the one and only “Asia expert” around, I was asked to come up with a book which would present “the Chinese case” in one week's time. I've been searching for a suitable introductory text ever since. 相似文献

Homicide by stab wound is common worldwide. However, the use of unusual edged weapons is rarely reported in the forensic literature. Here, we report two cases of homicide involving a Japanese sword, or katana, and a sickle. Both of these weapons can create either stab or incised wounds with some particularities. In our cases, characteristics of the external wounds, internal injuries, and the depth of penetration raised the possibility of an unusual weapon. Meticulous forensic examination of these injuries (morphological characteristics, depth of penetration, trajectories, and cut marks in the bone) may allow the forensic expert to determine the type of weapon used. 相似文献

Testing for drugs in hair raises several difficulties. Among them is the interpretation of the final concentration(s). In a post‐mortem case, analyses revealed the presence of furosemide (12 ng/mL) in femoral blood, although it was not part of the victim's treatment. The prosecutor requested our laboratory to undertake an additional analysis in hair to obtain information about the use of furosemide. A specific method was therefore developed and validated to identify and quantify furosemide in hair by UHPLC‐MS/MS. After decontamination of 30 mg of hair, incubation in acidic condition, extraction with ethyl acetate, the samples were analyzed by UHPLC‐MS/MS. Furosemide was found in the victim's hair at 225 pg/mg. However, it was not possible to interpret this concentration due to the absence of data in the literature. Therefore, the authors performed a controlled study in two parts. In order to establish the basis of interpretation, several volunteers were tested (four after a single 20 mg administration and twenty‐four under daily treatment). The first part indicated that a single dose is not detectable in hair using our method. The second part demonstrated concentrations ranging from 5 to 1110 pg/mg with no correlation between dosage and hair concentrations. The decedent's hair result was interpreted as repeated exposures. In the case of furosemide analysis, hair can provide information about its presence but cannot give information about dosage or frequency of use. 相似文献

This article argues that those keen to characterise and harness the empowering potential of Information and Communications Technology [ICT] for development projects must understand that the very existence of this technology opens up alternative models of co-operation and collaboration. These models themselves necessitate breaking away from ‘traditional’ command-and-control models of management. One alternative is to persuade participants, or potential participants, to co-ordinate their efforts along the lines exemplified by the open-source software movement and the contributors to Wikipedia: models of co-ordination that ought not to work but appear to do so. The article offers a summary of this argument, and then suggests ways in which NGOs in particular might try to incorporate these insights into their strategies. This is particularly critical for organisations that rely on increasingly pressurised funding opportunities, and which also seek to develop and engender participation and determination from within and among specific target groupings. 相似文献

Village funeral societies in north-east Thailand collect equal contributions from all participating households, even though some households are much more likely to experience deaths and receive money from the funeral society than others. The societies' use of the equal contributions rule is not an outcome of the asymmetric distribution of information on risks. It reflects, instead, an ambivalence over the relevance of expected returns, a willingness to subsidise fellow villagers, and the need to maximise simplicity and transparency to safeguard against mismanagement and corruption. The equal contributions rule is efficient, in that it leads to low administrative costs, has no clearly superior alternatives, and creates only minor adverse selection. 相似文献
