Taking the case of Georgia, this article considers the role of politico-economic networks in weakening the energy sector in a post-Soviet state. It is hypothesised that incentives, from financial gain to the provision of goods and services, encourage a multitude of actors to create an alternative system to the state. It concludes that in a weak state, networks have replaced legitimate channels of communication and no amount of foreign financial or technical assistance can make up for the lack of will among the stakeholders to develop an efficient energy system.  相似文献

Isotopic signatures used in the georeferencing of human remains are largely fixed by spatially distinct geologic and environmental processes. However, location-dependent temporal changes in these isotope ratios should also be considered when determining an individual’s provenance and/or trajectory. Distributions of the relevant isotopes can be impacted by predictable external factors such as climate change, delocalisation of food and water sources and changes in sources and uses of metals. Using Multi-Collector Inductively-Coupled Plasma Mass Spectrometer (MC-ICP-MS) analyses of 206Pb/207Pb in tooth enamel and dentin from a population of 21 ± 1-year-old individuals born circa 1984 and isotope ratio mass spectrometry (IRMS) of δ18O in their enamel, we examined the expected influence of some of these factors. The resulting adjustments to the geographic distribution of isotope ratios (isoscapes) found in tooth enamel and dentin may contain additional useful information for forensic identification, but the shifts in values can also impact the uncertainty and usefulness of identifications if they are not taken into account.

KEY POINTS

  • Isoscapes of 206Pb/207Pb and δ18O used for geolocation are not static.
  • Within a few years, the enamel and dentin of a person may exhibit measurable differences in 206Pb/207Pb even without changing locations.
  • Changes in climatic patterns tied to rising temperatures are more significant than the direct effect of increasing temperature on δ18O fixed in tooth bioapatite.
  • Third molar (M3) enamel mineralisation includes material incorporated from before formal amelogenesis takes place.

Previous research reveals that showups are an inferior eyewitness identification procedure to lineups, but no single study has compared younger and older adults' identification decisions for both of these procedures. We had witnesses watch a mock crime video and then make an identification decision from a fair lineup, a biased lineup, or a showup that contained the perpetrator or a designated innocent suspect. Receiver operating characteristic (ROC) analysis showed that identification accuracy was higher from a lineup than from a showup for both age groups, even if the lineup was biased. In addition, calibration curves revealed that witnesses were underconfident when choosing from a fair lineup but overconfident when choosing from a showup. These results reinforce prior research asserting the superiority of lineups over showups.  相似文献

This study uses an experimental design comparing 235 offenders assigned either to drug treatment court or treatment as usual. It extends prior analyses of this study sample to examine whether differences observed between drug treatment court subjects and control subjects at one and two years after the start of the program persist after three years, when many of the subjects had ceased active treatment. Further, it extends earlier analyses that showed that the quantity of drug treatment court services received was related to lower recidivism rates by using an instrumental variables approach to handle the endogeneity problem that sometimes arises when subjects self-select into different levels of service. Results show a sustained treatment effect on recidivism, controlling for time at risk. This effect is not limited to the period during which services are delivered. Rather, it persists even after participation in the drug court program ceases. Results also show that the recidivism is lowest among subjects who participate at higher levels in certified drug treatment, status hearings, and drug testing. These positive findings are tempered with findings that more than three-fourths of clients are re-arrested within three years, regardless of participation in the drug treatment court, and that drug treatment court cases spend approximately the same number of days incarcerated as do control cases. Implications for strengthening drug treatment courts are discussed.  相似文献

Conflict Avoidance and Political Participation   总被引:1,自引:0,他引:1  
Previous explanations of mass participation have often focused on sociodemographic characteristics to the neglect of social psychological factors. This study takes a new path in thinking about the role of psychological factors in participation. Specifically, we hypothesize that individual propensities regarding conflict will influence the likelihood of participating in political affairs. We develop more specific expectations for how the avenue of participation interacts with individual propensities toward conflict to influence participation. Using secondary analysis of the Citizen Participation Study (CPS), we show that conflict avoidance is significantly and inversely related to participation in some kinds of activities, consistent with our expectations. Thus, both individual propensities and the political context influence participation. This study provides a new understanding of which individuals participate in political affairs and which avenues they choose. This suggests a need to reconsider the role of psychological factors in models of participation.  相似文献

The cooccurrence of binge eating and increased alcohol intake and substance abuse has been reported in clinical and community epidemiological samples. To further investigate the nature and causes of this comorbidity, we examined the 10-year prospective, longitudinal course of illness in 95 nonsubstance abusing adolescents hospitalized for treatment of anorexia nervosa. Survival analysis with Cox regression was used to quantitate the cumulative risk of developing substance use disorder (SUD) as a function of patterns of binge eating vs. dietary restraint within this cohort. Subjects who were binge eating at the time of intake were robustly distinguished from restrictors, having increased risk of SUD as well as greater likelihood of having at least one first-degree relative with SUD. The findings suggest binge eating that develops in the underweight stage of anorexia nervosa may reflect developmental, biological, and genetic risk processes shared in common with SUD.Received Ph.D. in clinical psychology from the University of Pittsburgh.
