The estate tax has many advocates and opponents. We present a review of the primary arguments and empirical evidence promulgated in support of continuation and for repeal. Overall, we find that there are plausible theories and strong, but not definitive, empirical evidence on both sides of the issue. Further research is needed that more clearly isolates differences between the income‐tax and estate‐tax (that is, the after‐tax cost or “price” of a donation or bequest) effects, the independent‐income and wealth effects (how having higher income or wealth has an effect on giving during life and at death), and married and single estate tax filers. These differences can be best isolated using longitudinal data. Data and analyses for both the short run and long run are necessary before society can reasonably predict the impact the repeal of the estate tax will have on both giving during life and charitable bequests. 相似文献

Few studies have evaluated how participation in violence that occurs on the streets as part of criminal or delinquent behavior relates to violence that occurs as part of dating or marital relationships (partner violence). Using longitudinal data from 141 African American and Latino male youth (15–19 years old), the relation between family characteristics and participation in one or both types of violent behavior was evaluated. The youth in this study were more likely to report use of violence in relationships if they were also participating in violence as part of other criminal behavior. However, there were distinct groups of offenders. Among those males reporting involvement in a dating or romantic relationship, four groups were identified: (1) those who had not participated in either type of violence, 57%; (2) those who had participated in partner violence only, 14%; (3) those who had participated in street violence only, 12%; and (4) those who had participated in both, 17%. Discriminate function analyses significantly differentiated the group who had participated in both types of violence from the nonviolent group, with the former group having poorer functioning families. These two groups were also differentiated from the partner violence‐only and street violence‐only groups. No differences were found between the partner violence‐only and the street violence‐only groups. Implications for intervention and prevention are discussed. 相似文献

Quantitative approaches to assessing exposure to, and associated risk from, benzene in mineral spirits solvent (MSS), used widely in parts washing and degreasing operations, have focused primarily on the respiratory pathway. The dermal contribution to total benzene uptake from such operations remains uncertain because measuring in vivo experimental dermal uptake of this volatile human carcinogen is difficult. Unprotected dermal uptake involves simultaneous sustained immersion events and transient splash/wipe events, each yielding residues subject to evaporation as well as dermal uptake. A two‐process dermal exposure framework to assess dermal uptake to normal and damaged skin was applied to estimate potential daily dermal benzene dose (Dskin) to workers who used historical or current formulations of recycled MSS in manual parts washers. Measures of evaporation and absorption of MSS dermally applied to human subjects were modeled to estimate in vivo dermal uptake of benzene in MSS. Uncertainty and interindividual variability in Dskin was characterized by Monte Carlo simulation, conditioned on uncertainty and/or variability estimated for each model input. Dermal exposures are estimated to average 33% of total (inhalation + dermal) benzene parts washing dose, with approximately equal predicted portions of dermal dose due to splash/wipe and to continuous contact with MSS. The estimated median (95th percentile) dermal and total daily benzene doses from parts washing are: 0.0069 (0.024) and 0.025 (0.18) mg/day using current, and 0.027 (0.085) and 0.098 (0.69) mg/day using historical, MSS solvents, respectively. 相似文献

This article offers a new explanation for the sudden rise in popularity of French existentialism, in particular of Sartre’s
version, in the mid-1940s. It develops a multidimensional account that recognizes both structural and cultural factors. The
explanation differs from, and more fully addresses the complexity of the situation than, the two most prominent existing explanations:
namely Anna Boschetti’s Bourdieu-inspired account and Randall Collins’s network-based approach. It is argued that, because
of specific socio-political circumstances, the intellectual establishment became tainted and lost legitimacy, with its aesthetic
and philosophical views now regarded as outdated if not politically dangerous. This hiatus brought unprecedented publishing
opportunities for a new philosophical current, and skilful public performances by the main protagonists helped its ascendancy.
Most importantly, existentialist writers colluded with de Gaulle in portraying a cohesive and defiant French nation; and their
philosophy, especially in its notion of responsibility, enabled sections of French society to assimilate and make sense of
the recent past, whilst drawing a line underneath it so as to move forward. 相似文献

This article looks at the relationship between logistical power and the assemblages of sites that constitute modern states. Rather than treating states as centralizing institutions and singular sites of power, we treat them as multi-sited. They gain power by using logistical methods of problem solving, using infrastructures to enforce and depersonalize relations of domination and limit the autonomy of elites. But states necessarily solve diverse problems by different means in multiple locations. So, educating children is not continuous with governing colonies even though both are necessary to nineteenth-century states. For this reason, states use logistical means of coordination to link sites, and they make the power of the state seem unitary even though the exercise of state power is not. 相似文献

HIV and population dynamics: A general model and maximum-likelihood standards for East Africa 总被引:2,自引:0,他引:2
Heuveline P 《Demography》2003,40(2):217-245
In high-prevalence populations, the HIV epidemic undermines the validity of past empirical models and related demographic techniques. A parsimonious model of HIV and population dynamics is presented here and fit to 46,000 observations, gathered from 11 East African populations. The fitted model simulates HIV and population dynamics with standard demographic inputs and only two additional parameters for the onset and scale of the epidemic. The underestimation of the general prevalence of HIV in samples of pregnant women and the fertility impact of HIV are examples of the dynamic interactions that demographic models must reproduce and are shown here to increase over time even with constant prevalence levels. As a result, the impact of HIV on population growth appears to have been underestimated by current population projections that ignore this dynamic. 相似文献
