With the aim of investigating factors affecting willingness to pay for municipality child care, a survey was undertaken in Sweden of 1840 parents living in five municipalities of different sizes. On the basis of the greed-efficiency-fairness hypothesis (Wilke, 1991) which is supported by results from experimental social dilemma research, it was hypothesized that perceived fairness of how the quality of child care is distributed (equal, proportional to need, or proportional to payment) as well as of method of payment (collectively by taxes or proportional to use by fees) would be important determinants of willingness to pay. Results showed that perceived fairness of how quality of child care is distributed played some role but that other factors had stronger effects. Perhaps also reflecting fairness considerations, willingness to pay by fees was on average higher than willingness to pay by taxes. Predicted from previous research, willingness to pay by taxes was furthermore found to increase with income and degree of use. However, willingness to pay by taxes showed an increase rather than the predicted decrease with municipality size.  相似文献

This paper reports on a new methodology to estimate the “cost of crime.” It is adapted from the contingent valuation method used in the environmental economics literature and is itself used to estimate the public's willingness to pay for crime control programs. In a nationally representative sample of 1,300 U.S. residents, we found that the typical household would be willing to pay between $100 and $150 per year for programs that reduced specific crimes by 10 percent in their communities. This willingness amounts, collectively, to approximately $25,000 per burglary, $70,000 per serious assault, $232,000 per armed  相似文献

The validity and feasibility of using DNA collection cards in the field for preservation and analysis of Cannabis sativa genotypes were investigated using a highly specific hexanucleotide marker. Collection cards were submitted to the National Marijuana Initiative, which selectively trained and managed the collection of specific types of samples from a variety of participating agencies. Samples collected at seizure sites included fresh marijuana leaf samples, dried "dispensary" samples, U.S. border seizures, and hashish. Using a standardized PCR kit with custom-labeled oligonucleotide primers specific to marijuana, collection cards produced eight genotypes and 13 different alleles, extremely low baselines, and no cross-reactivity with control plant species. Results were produced from all sample types with the exception of hashish. Plant DNA collection cards represent an easily implementable method for the genetic identification and relatedness of C. sativa street and grow site-seized samples with applications for databasing and market disruption.  相似文献

Studies of empirical relationships between indicators of prison crowding and inmate violence have uncovered null, negative, and positive relationships. These mixed findings may be due, in part, to cross‐study differences in definitions of crowding, levels of analysis, and sample designs. We compared findings across some of the more popular approaches to study the relationship between facility crowding and the prevalence of inmate assaults in order to determine the implications of different methods for variation in estimates. Multi‐level data from a national sample of 10,022 men confined in 203 state correctional facilities during 1997 were examined. Findings revealed differences across methods in the direction and significance of the crowding/assault relationship. These differences were then considered in order to derive a strategy for more uniform research on the topic. This strategy consists of including both total inmate population and design capacity as separate predictors in the same model, examination of tri‐level data (inmates, facilities, and states) in order to control compositional differences in inmate populations across facilities and to remove confounding state‐level differences in crowding levels and assault rates, and more careful consideration of secondary analyses of complex samples with sample weights.  相似文献

Public-goods dilemmas are characterized by conflicts between self-interest and the welfare of a group or society at large. Research has identified several factors that enhance cooperation in such dilemmas. However, less is known about how concern for distributive justice affects willingness to contribute in asymmetric public-goods dilemmas. To test the hypothesis that contributions to a common resource is related to perceived fairness, experiments were performed to investigate willingness to pay to the social service of child care in hypothetical societies. Experiment 1 aimed at replicating a previous survey study (Biel et al., 1997). Experiments 2 and 3 were extensions. In all three experiments subjects were asked to indicate how fair they considered different distributions of the quality of child care provided by their municipality. These distributions corresponded to the principles of equality, equity, and need. University students (32, 48, and 32 in the three experiments, respectively) served as subjects. Ratings of perceived fairness were positively related to willingness to pay. Other factors also positively related to willingness to pay included ability to pay, personal need, expected payment from others, and the number of households who had to contribute in order to maintain the quality. Furthermore, decreasing municipality size increased willingness to pay.  相似文献

Previous criminological studies comparing institutional youth populations with community samples have for the most part focused on youths institutionalized primarily as a result of involvements in delinquency. The present study compares levels of social disadvantage and criminal involvement within a nationally representative sample of Swedish schoolboys with those of a national population of institutionalized males that includes both serious young offenders and youths institutionalized for other reasons. Whilst at the aggregate level, mean levels of offending are higher within the institutional sample, the institutional population includes youths from across the entire range of levels of offending. Levels of social disadvantage are substantially elevated among the institutionalized males by comparison with the school sample. The study notes that institutionalized samples, where these include both young offenders and youths institutionalized for other reasons, may provide a fruitful ground for life‐course research into the way involvements in crime interact with other indicators of social disadvantage to affect the likelihood of continued marginalization into adulthood.  相似文献

As a result of the decentralized system of American criminal justice, state information systems have developed in a fragmented manner. Thus, the availability of justice data, which is one product of these systems, varies greatly between states. Although these disparities are widely acknowledged, very little information exists on the extent of the disparities. This article compares data availability across states as well as the level of computerization of these data, and the facility with which criminal justice agencies share the data with other state justice agencies. These variables are important because thorough data availability, a high level of computerization, and a willingness to share existing data can increase the quality and timeliness of criminal justice policy making.  相似文献

We assess the potential of increased economic competition by examining whether Medicare beneficiaries are willing to switch to physicians who agree to accept all services on assignment. Data come from a survey of Medicare beneficiaries conducted in November 1988. Our principal finding is that beneficiaries are not sensitive to price when making decisions about whether or not to switch physicians. Less than one-half of 1 percent of the sample had switched physicians for economic reasons in the year prior to the survey. Furthermore, willingness to switch was not correlated with ability to pay. We conclude that policies aimed at altering consumer demand may not be the most effective way to control Medicare costs.  相似文献

The U.S. government estimates that 600,000 to 800,000 persons are trafficked across international borders annually; however such estimates of global human trafficking are questionable. The accuracy of the estimates is in doubt because of methodological weaknesses, gaps in data, and numerical discrepancies. For example, the U.S. government's estimate was developed by one person who did not document all of his work, so the estimate may not be replicable, casting doubt on its reliability. Moreover, the quality of existing country level data varies due to limited availability, reliability, and comparability. There is also a considerable discrepancy between the numbers of observed and estimated victims of human trafficking. The U.S. government has not yet established an effective mechanism for estimating the number of victims or for conducting ongoing analysis of trafficking related data that resides within various government agencies.  相似文献

ABSTRACT

This article examines the determinants of demand for cinema using a randomly drawn sample of the movie-going population in Sweden. A proportional odds model is applied to capture the natural ordering of dependent variables and any inherent nonlinearities. The findings show that individual demand for cinema depends on gender, age, educational attainment, income, marital status, critical reviews, word of mouth, and willingness to pay. The fact that cinema demand is correlated with economic and socio-demographic variables has important implications for theoretical and empirical research in cultural economics and human decision-making processes.  相似文献

Abstract:  With improvements in manufacturing procedures, comparing physical characteristics of paper samples may not offer sufficient discrimination among different vendors. In this work, the potential to differentiate paper samples based on trace element concentrations was investigated. Paper samples from two different vendors were microwave-digested and trace element concentrations (Mg, Al, Mn, Fe, Sr, Y, Ba, Ce, and Nd) were determined using inductively coupled plasma–mass spectrometry. Differences in concentration were assessed statistically using two-way ANOVA and Tukey's honestly significant differences test. Elemental concentrations were shown to be consistent across a single sheet as well as within a single ream of paper for each vendor. Reams from vendor A were differentiated based on Al and Ba concentration while reams from vendor B were differentiated based on Mg, Mn, and Sr concentrations. Paper was differentiated according to vendor based on significant differences in Ba, Sr, Ce, and Nd concentrations.  相似文献

A Developmental Approach for Measuring the Severity of Crimes   总被引:1,自引:1,他引:0  
There is widespread agreement in criminology that some crimes are more severe than others, but precise definitions of crime severity and straightforward methods for measuring it have been elusive. Public perceptions of crime severity and economic estimates of crime costs to society or willingness to pay offer a variety of metrics for the public’s perceptions of severity, but they may not accurately describe severity as reflected in offender preferences. The behavior of offenders is critical for understanding developmental progressions in criminal careers, as one may assume that typically more severe offenses are not undertaken until less severe crimes have been committed. In the present paper we propose an alternative metric of crime severity, drawing on findings from developmental criminology that indicate that more severe crimes occur after less severe crimes in the criminal life course, and a method for estimating crime severity that uses the generalized Bradley–Terry model of multiple paired comparisons. We demonstrate this approach on two samples of youthful offenders: the National Youth Survey and the RAND Adolescent Outcomes Project. The results suggest that sample-specific estimates of crime severity can be derived, that these estimates provide insight into the developmental progression of crime, and that they correspond well to crime severity rankings produced by the public.

There is a paucity of data available on the effect of storage on blood alcohol concentration (BAC) at elevated temperatures. Changes in serum alcohol concentration (SAC) and BAC were studied. Serum samples spiked with alcohol in the presence or absence of preservative were stored at 26.7 °, 32.2 ° or 37.8 °C respectively. Serum alcohol concentrations were determined daily on days 1 through 14, and on days 21 and 35. Under these controlled conditions, no significant change in SAC was observed at the aforementioned temperatures. Whole blood samples submitted from outside agencies were initially analyzed (day 1), then stored for 35 days at different elevated temperatures before a second analysis. The average loss in BAC was 19.20 ± 15.6, 9.95 ± 5.7, and 15.60 ± 6.9% when the samples were stored at 26.7, 32.2 and 37.8 °C, respectively. The alcohol loss from whole blood samples may be attributed to chemical oxidation rather than to elevated temperatures. It is, therefore, concluded that a whole blood sample obtained from a living individual and stored in a locker, glove compartment or other environment where the temperature is elevated, may lose 10–19% of its alcohol content over 35 days of storage. On the other hand, when a serum or plasma sample is exposed to the same environment, no significant change in SAC was observed. The utility of this information is significant to the forensic toxicologist. The results of this study suggest that a whole blood sample analyzed after exposure to elevated temperature may have had, originally, a higher BAC.  相似文献

Gas chromatography-mass spectrometry was used to compare gasoline samples obtained from different sources based on the difference in amounts of certain components found in the headspace of gasoline using target response data. Many suspected arson cases involve comparing an ignitable liquid extracted from fire debris to a liquid found in a suspect's possession to determine if they could have had a common source. Various component ratios are proposed for determining if an unevaporated gasoline sample could have originated from the same source as an evaporated gasoline extracted from fire debris. Fifty and 75% evaporated gasoline samples were both found to contain similar ratios of certain components when compared with its unevaporated source gasoline. The results of the comparisons in this study demonstrate that for cases involving gasoline that has been evaporated up to 50% and extracted from pine, it is possible to eliminate comparison samples as originating from the same source. The results of the 75% comparisons suggest it may be possible to apply the same type of comparison to cases involving 75% evaporated gasoline.  相似文献

Data were collected from women seeking admission to a spouse abuse shelter in a small southern city. The questionnaire which they completed requested demographics and a wide variety of attitudinal data. The paper reports an analysis of the women's perceptions of police responses to their victimization, their feelings towards self, and their willingness to pursue mobilization of the law in their own behalf. It was reported that the police rarely made referrals to helping agencies and that the most common police action was to “talk” to the assaulter/batterer. Victims' feelings toward self were not nearly as negative overall in this sample as is typically assumed of abused women. Some support was found for a series of hypotheses that positive police responses enhance the victims' self-image and encourage them to seek mobilization of the law.  相似文献

Each government agency uses a uniform figure to measure the value of a statistical life (VSL). This is a serious mistake. The very theory that underlies current practice calls for far more individuation of the relevant values. According to that theory, VSL should vary across risks. More controversially, VSL should vary across individuals -- even or especially if the result would be to produce a lower number for some people than for others. One practical implication is that a higher value should be given to programs that reduce cancer risks. Another is that government should use a higher VSL for programs that disproportionately benefit the wealthy -- and a lower VSL for programs that disproportionately benefit the poor. But there are two serious complications here. First, bounded rationality raises problems for the use of private willingness to pay, which underlies current calculations of VSL. Second, the beneficiaries of regulation sometimes pay only a fraction or even none of its cost; when this is so, the appropriate VSL for poor people might be higher, on distributional grounds, than market evidence suggests. An understanding of this point has implications for foundational issues about government regulation, including valuation of persons in poor and wealthy nations.  相似文献

This paper compares composite crime indexes across two alternative data sources—the Uniform Crime Reports (UCR) and the National Crime Survey (NCS). A variety of indexes are constructed based on weights derived from Sellin and Wolfgang's “seriousness” scale. The results reveal that indexes weighted by offense seriousness are not very highly correlated across data sources for a sample of twenty-six American cities. The substantive importance of the discrepancies between UCR and NCS estimates is illustrated by examining the ecological correlates of weighted crime rates for the twenty-six city sample and by assessing changes in weighted crime rates at the national level for the 1973-81 period. The results also reveal that if estimates of homecide are included in the composite indexes by supplementing the NCS data with data from the Center for Health Statistics, then under certain weighting conditions the correlations across data sources are nearly perfect. The paper concludes with a discussion of the implications of this latter finding for the measurement of overall levels of criminal activity and for the scaling of the relative gravity of different offenses.  相似文献

Abstract: The choice of reagents for presumptive tests for blood, and subsequent extraction methodologies, can significantly affect both the quantity and quality of purified DNA. Blood samples directly tested with Hemastix® yielded <1% of the DNA recovered from untested samples when purified using the Qiagen BioRobot® EZ1 and EZ1® DNA Investigator kit. Full short tandem repeat profiles were obtained from both tested and untested samples, suggesting that the Hemastix® reagent(s) affect DNA binding, rather than produce DNA damage. The Hemastix® inhibition of DNA yield could be overcome by the addition of MTL buffer to the sample prior to extraction. Laboratories may wish to modify current procedures for extracting blood samples, utilize other extraction/purification methodologies, or inform their submitting agencies to avoid direct exposure of questioned bloodstains to Hemastix® reagents.  相似文献

Preventing repeat victimization is an area of criminology that has shown particular promise in recent years. Based on the premise that persons once victimized are at higher risk than others for future victimization, British officials developed successful programs that focus crime prevention efforts on victims. Of all crimes, family violence may have the highest repeat rate, especially in the first weeks after an incident is reported to the police. Accordingly, New York City officials developed an intervention program to reduce repeat incidents of family abuse. Three field experiments conducted during the 1990s evaluated whether or not this program, targeted at public housing residents who reported family violence to the police, reduced the rate of subsequent victimization. The findings produced within each study were not consistent across the studies; rather, these three experiments, separately analyzed, produce varying results. Since the composition of the samples varied across studies, however, one possible explanation is that this program has different effects within different populations. This paper reports outcomes from a series of analyses of pooled data from these three studies to address the inconsistencies. The results indicate that the intervention brought about greater reporting of subsequent abuse both to authorities and to research interviewers. The results are invariant across the three studies, indicating that greater reporting of abuse is not idiosyncratic to one particular population, and are consistent across the nature and source of outcome measures. These findings suggest the need for careful monitoring by the advocates and agencies that operate these types of programs and among those designing and testing future programs.  相似文献

Police and court liaison and diversion services provide important specialist mental health input along critical stages of the criminal justice pathway. Effective sharing of information between the services and relevant justice agencies is essential. However, various problems exist with the flow of information between agencies and services across the criminal justice pathway. This service evaluation explored how clinically relevant information is transferred, by drawing on the perspectives of prison health care staff in a large urban UK male prison. A qualitative service evaluation was conducted using semi-structured interviews with a purposive sample of 11 prison staff. The main themes included: gaps in the transfer of essential information, (particularly concerning risk and offending information); information gathering to fill these gaps; the importance of professional relationships, information sharing between agencies; and information solutions. Improving information transfer across the criminal justice pathway could prevent treatment delays and ensure more timely mental health care in prison.  相似文献
