When do states allow nonstate actors (NSAs) to observe negotiations at intergovernmental meetings? Previous studies have identified the need for states to close negotiations when the issues under discussion are sensitive. This paper argues that sensitivity alone cannot adequately explain the dynamic of closing down negotiations to observers. Questions that have received little attention in the literature include which issues are considered sensitive and how the decision is made to move the negotiations behind closed doors. This paper examines the practices of NSA involvement in climate diplomacy from three analytical perspectives: functional efficiency, political dynamics, and historical institutionalism. Based on interviews and UNFCCC documents, this paper suggests that to understand the issue of openness in negotiations, institutional factors and the politics of NSA involvement need to be better scrutinized. The paper shows that each perspective has particular advantages when analyzing different dimensions of the negotiations, with implications of how we understand the role of NSAs in global environmental governance.  相似文献

In a study of relocation decisions at seven different sites, procedural fairness was shown to be more sensitive to outcome fairness when respondents had less time to gather information about decision procedures. We interpret this finding to show that inaccessibility of information about decision procedures moderates the influence of outcome fairness judgments on procedural fairness judgments, such that outcome recipients rely more heavily on outcome fairness as a basis for forming procedural fairness judgments when information about decision procedures is not available. A second, laboratory study is reported that confirms the information inaccessibility explanation in the first study. When procedural information is available, procedural characteristics may be the primary bases for procedural fairness judgments, but when such information is unavailable, procedural fairness will likely be more sensitive to self-interest concerns. Future research should therefore take contextual factors such as accessibility to procedural information into account, given that there are likely to be differences on that dimension between organizational settings on the one hand and legal, political, and dispute resolution settings on the other. Information about decision procedures, generally accessible in legal, political, and dispute resolution settings, is often much less accessible in organizations.  相似文献

This study tested the ability of experienced interviewers and novice observers to detect deception while watching mock interviews featuring experimental or control questioning methods and different detainee languages. The protocol featured a complex, realistic critical event and naturalistic interviews in which mock detainees could report unconstrained. Experimenters recorded these interviews and presented them to observers who judged veracity in real time. In general, experienced interviewers were no more sensitive to deception than were novices and both groups set conservative response criteria. Observers were more sensitive to deception when viewing control versus experimental questioning methods. Observers were more sensitive to deception when viewing Arabic speakers interviewed through an interpreter. Results imply that not all trained interviewers exhibit a lie bias; additional research should examine how best to transition lab-tested interview methods into the field, and language and interpreter factors may impact the ability to assess veracity in multiple ways.  相似文献

Neuroimaging in mild traumatic brain injury (mTBI) is reviewed. While computed tomography remains the acute standard for neuroimaging of mTBI, it is only sensitive to gross abnormalities and is typically performed as a measure to rule out more serious and life-threatening injury. Magnetic resonance imaging (MRI), especially at field strength of 3.0 T, is the follow-up neuroimaging standard for assessing potential underlying structural injury to the brain. Several MRI sequences are particularly sensitive to subtle hemorrhagic lesions and signal abnormalities in white matter, sensitive enough to detect pathology when present in mTBI. Clinical correlation of neuropsychological outcome with neuroimaging findings is discussed along with the future potential for functional neuroimaging in evaluating the mTBI patient.  相似文献

Ethical principles are often presented as universal, immutable rules. However, when conducting research with ethnic minority groups, such as Asian Americans and immigrants, ethical issues need to be placed within a sociocultural context as ethical responses are filtered through the specific value orientations and belief systems of the ethnic group under study. Further, when the group is a marginalized population, power dynamics complicate ethical principles of autonomy. The complexities are further accentuated with sensitive topics such as intimate violence or domestic violence. Consequently, ethical questions about autonomy, informed consent, confidentiality, limits to confidentiality, and protecting participants’ safety and reducing distress need to be at the forefront when planning intimate violence research. An overview of sociocultural context of Western biomedical ethics is presented and specific ethical issues that emerge when conducting intimate violence are discussed.  相似文献

To evaluate the diagnostic role of histochemically demonstrated aerobic dehydrogenases in ischemic myocardial injury NADH-diaphorase, succinate dehydrogenase (SDH), beta-hydroxybutyrate dehydrogenase (HBDH) and malate dehydrogenase (MDH) were demonstrated histochemically and the corresponding enzyme activities were measured biochemically in isolated perfused rats hearts after global ischemia from 0 to 12 h. The present data show that the enzyme-histochemical methods when used properly are more sensitive indicators of early ischemic injury than classical histological staining procedures. From the enzymes tested here the histochemical demonstration of HBDH turned out to be best suited for use when suspecting ischemic myocardial injury at autopsy.  相似文献

Compared to American trial procedures, British procedures provide a less distracting environment in which jurors can process trial evidence. Relying on theories of persuasion, it was predicted that jurors viewing British procedures would be less affected by extra-evidentiary cues and would be more sensitive to evidence strength variations than jurors in American trials. Participants (N = 245) viewed a mock trial in which trial procedure, judge's nonverbal behavior, and evidence strength were varied. Participants judged the British procedures to be more civil and fair than American procedures but were less likely to find for the plaintiff. Although jurors recalled more trial facts when they viewed British procedures, they were not more sensitive to variations in evidence strength. There was some evidence that British procedures may increase the influence of judge's nonverbal behavior on juror judgments. The relative benefits of different trial procedures are discussed.  相似文献

We investigated the previously unstudied relationship between procedural justice and identification within virtual teams, with a particular focus on how two features of virtual teams, namely frequency of face-to-face meetings and geographical dispersion, moderate that relationship. We argue that these two variables are sources of uncertainty, which in turn makes virtual team members more sensitive to perceptions of procedural fairness as essential cues in the identification process. In this study, we used cross-sectional survey methodology and data aggregated to the team level (N = 39). As predicted, our results showed that the link between procedural justice and identification was stronger when there were few face-to-face meetings and when teams were highly dispersed.  相似文献

When mitochondrial DNA (mtDNA) heteroplasmies are detected, they often confound forensic identification, especially if they are the result of poor biological sampling. In this study, we determined the ratio of heteroplasmy in samples that were amplified from a very small amount of template mtDNA or a few cells using a highly sensitive nested polymerase chain reaction (PCR) procedure and a direct sequencing analysis. As a result, more than half of the detected sequences (i.e., 17/20, 15/20, and 14/20) showed homoplasmy derived from a variation in the heteroplasmy proportion when only 10 copies of template mtDNA samples were amplified and analyzed. Additionally, with products amplified from one or several white blood cells (WBCs), several previously undetected heteroplasmies were detected. These results indicate the risks associated with using highly sensitive mtDNA techniques in forensic investigations because of the variable proportions of heteroplasmy or nucleotide substitutions that can possibly be detected from a very small biological sample.  相似文献

The increased use and abuse of methadone in recent years has posed a problem of both its identification and quantitation in body tissues. Recent development of a radioimmunoassay for methadone appears to have solved the problem. In our hands the assay was extremely sensitive and specific. It also appears to be an excellent tool when quantitative estimates are to be obtained. Although it initially appears to be relatively expensive, the time saved in doing a complete tissue distribution equalizes the cost. It is hoped that other radioimmunoassays currently under development will prove as satisfactory.  相似文献

Hordenine cross-reacted with various enzyme linked immunosorbent assay (ELISA) or radioimmunoassay (RIA) kits used for the screening of urine samples. Morphine-ELISA kit was most sensitive, whereas etorphine- and buprenorphine-ELISA kits were least sensitive to hordenine cross-reactivity. Hordenine also interfered with the thin layer chromatography of oxymorphone, hydromorphone and apomorphine. The major source of hordenine in humans is beer brewed from barley, whereas the major source of hordenine in horses is canary grass or barley. Therefore, the presence of hordenine in the urine of humans consuming beer or in the urine of horses consuming canary grass may give false positive values when the immunoassay and TLC methods are used for the screening of the urine sample. In order to distinguish hordenine from the opiate drugs, simple and sensitive gas chromatographic/mass spectrometric (GC/MS) and high performance liquid chromatographic (HPLC) methods have been developed in this study.  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

Using Swedish rape statistics as a focus, this article aims to empirically describe the way in which different factors affect official crime statistics produced at the national level. It is argued that cross-national comparisons of crime levels are extremely hazardous when based on official crime statistics, since the construction rules vary widely. International comparisons of crime levels should as a rule be confined to findings of international victim surveys. The example of rape statistics in Sweden - about three times higher when compared to other countries in the European Sourcebook - is used to explain what factors can influence statistics. Statistical, legal and substansive factors are to be taken into account. The author shows that changes in statistical routines, the legal definition of rape and changes over time all influence the statistics in a substansive way. This article indicates the great extent to which crime statistics are a construct, whose appearance is very sensitive to the rules applied in the process of construction. In order to employ statistics appropriately, a thorough knowledge of the principles guiding this process is therefore essential.  相似文献

This research attempts to elaborate a routine activity model of violent victimization by incorporating an explicit rational choice perspective on potential targets’ decision making to avoid violent encounters. We propose that the costs associated with a violent attack and the probability of offender retaliation depend on whether the offender's targeting strategy is opportunistic or deliberate—a function of the relational distance between the offender and target. Specifically, we propose that victim efforts to limit exposure to an offender may motivate a violent retaliatory response when the victim and offender are intimates compared to when they are strangers. We develop hypotheses based on these ideas and test them using data from the National Crime Victimization Survey (1992–2000). The results suggest that female targets are more sensitive to an offender's targeting strategy than are males. We conclude with a discussion of how knowledge of the potential risk of violent retaliation on the part of intimate and spousal offenders can be used to create more efficacious policies to protect victims of violence.  相似文献

Doe demonstrates that once an employer enters into a relationship with an individual and thereafter determines that he or she may be disabled, the employer has the right to ask the individual questions about the possible disability when those questions are relevant to assessing his or her qualifications for continuing on the job. In fact, once a health care provider is on notice that an employee's or physician's disability may render the employee or physician no longer qualified, thereby potentially endangering patients, the provider is required to determine whether the person is qualified for the job. In these sensitive matters, employers must draw a fine line between unreasonably following up on every rumor on the one hand, and on the other hand investigating reliable information when there may indeed be a direct threat to patients.  相似文献

This article examines how the power of majority‐party leaders to set the legislative voting calendar influences policy change in American state legislatures. By generating an opportunity for party leaders to exercise gatekeeping or negative agenda control, such rules introduce an additional partisan veto player into a system of governance. This addition typically increases the size of the core or gridlock interval, which drives policy change downward. Using both traditional data on bill passage counts and new data on Affordable Care Act compliance, I find strong support for these claims. More specifically, when I calculate core sizes that are sensitive to agenda rules, I find that agenda‐control‐adjusted core size is negatively correlated with policy change, as expected. Moreover, even when I match states on their overall preference dispersion or polarization, the ability of party leaders to exercise negative agenda control is strongly negatively associated with policy change.  相似文献

More and more researchers, evaluators, and policy makers are recognizing that in order to best understand the factors precipitating, supporting, and prohibiting intimate violence against women, we must often gather information directly from battered women themselves. Such data collection, however, is not without its risks to the women involved in such studies. It is important that researchers and evaluators consider ethical issues, especially but not limited to those related to safety and confidentiality, before attempting to gather information either directly from battered women or through their records or files. This article provides a number of practical strategies and protocols that have been used successfully when gathering sensitive information from and about women with abusive partners.  相似文献
