The primary aims of this article are (a) to examine the importance of cultural norms and what part they play in requiring us to tolerate others out of respect, and (b) to formulate some guidelines designed to prescribe boundaries to liberty and tolerance conducive to safeguard the rights of individuals and, in turn, democracy. I argue that a liberal democracy can interfere in the business of its sub‐cultures when some cultural norms subvert the basic principles upon which a liberal society is founded. I proceed by making a further radical claim that democracy may prevent cultural groups from entering society if their conceptions of the good essentially conflict with its norms. My basic argument is that considerations of context and intentions must be taken into account, and that they may require the introduction of constraints. I conclude by considering the question whether or not the intolerant group has any right to complain, arguing that it does not.1  相似文献

In many countries, the law permits state authorities to detain noncitizens before deportation. Typically judicial decisions about preremoval detention must be made within a short period of time during which deportable noncitizens are held in police premises, and depending on the country detention may last just one month (e.g., France) or up to 18 months (the Netherlands). While previous research has explored various dimensions of noncitizen detention including the legal procedure, health consequences, the condition of detention centers, and the lives of deportable noncitizens, the empirical assessment of the determinants of decisions on preremoval detention are largely unexplored. Using data from court proceedings of police petitions of detention in Spain and a quantitative strategy, in this article we undertake an empirical analysis of noncitizen detention combining personal background of deportable noncitizens, legal factors of the case, and the behavior of different actors involved in the procedure. To do it, we fit models that take into account variation occurred at judicial district levels. Results indicate, on the one hand, that relevant actors involved in the procedure use different informational cues to decide on cases. On the other hand, the role of prosecutors and attorneys during hearings proves also relevant to predict detention.  相似文献

A flow‐injection analysis tandem mass spectrometry (FIA MSMS) method was developed for rapid quantitative analysis of 10 different inorganic and organic explosives. Performance is optimized by tailoring the ionization method (APCI/ESI), de‐clustering potentials, and collision energies for each specific analyte. In doing so, a single instrument can be used to detect urea nitrate, potassium chlorate, 2,4,6‐trinitrotoluene, 2,4,6‐trinitrophenylmethylnitramine, triacetone triperoxide, hexamethylene triperoxide diamine, pentaerythritol tetranitrate, 1,3,5‐trinitroperhydro‐1,3,5‐triazine, nitroglycerin, and octohy‐dro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine with sensitivities all in the picogram per milliliter range. In conclusion, FIA APCI/ESI MSMS is a fast (<1 min/sample), sensitive (~pg/mL LOQ), and precise (intraday RSD < 10%) method for trace explosive detection that can play an important role in criminal and attributional forensics, counterterrorism, and environmental protection areas, and has the potential to augment or replace several of the existing explosive detection methods.  相似文献

Anatomical landmarks are considered the most objective indicators for use in forensic facial comparisons. Therefore, accurately identifying and locating these landmarks is the beginning of reliable facial comparison. This study evaluated the accuracy with which facial landmarks are located and examined their reliability according to type of landmark, head posture, and image quality. Nine operators located a series of landmarks on prepared facial images used to produce comparison images. Then, the average distances between the reciprocal landmarks (ADRL) on the reference and the comparison images were measured as indicators of landmark reliability. We found that a set of landmarks had higher or lower reliability as a function of the head angle and image quality. More reliable landmarks were associated with certain head postures and degrees of image quality. These should be used for facial comparison analysis depending on various head and image conditions.  相似文献

Once thousands of dollars, direct‐to‐consumer (DTC) genetic testing has become affordable and readily accessible in recent years. The technology can reveal a wealth of information to consumers: health risks, ancestry composition, and connections to genetic matches through relative databases. However, the law has not yet regulated many aspects of this new technology. This article analyzes how the law should regulate DTC genetic testing within the context of gamete donation. It will argue that gamete donors’ privacy interests warrant state regulation of DTC genetic testing kits and their associated genetic relative databases. It will also explore how state regulation should balance the competing interests of gamete donors and of donor‐conceived individuals.  相似文献

The United Nations (UN) system comprises several intergovernmental organizations (IGOs) that were established to contribute to the functioning of the overall transnational system of delivering global public goods. However, many IGOs under the UN system are criticized for their failure to accomplish their mandates. Research argues that IGO boards serve as a governance mechanism that should be designed in order to effectively perform the monitoring function to ensure fulfillment of IGO mandates. Thus, using an inductive fuzzy set qualitative comparative analysis, this study explores 13 IGO boards under the UN system to identify the board designs that are associated with highly effective monitoring. Our findings reveal a board design typology reflecting the interplay of the level of organizational complexity and the extent of the distribution problem in IGOs. This research contributes to our understanding of IGO governance by underscoring the relationship between board designs and highly effective monitoring to help researchers and practitioners improve IGO performance.  相似文献

A fire experiment conducted in a British 1950s‐style house is described. Measurements of temperature, smoke, CO, CO2, and O2 were taken in the Lounge, stairwell, and front and back bedrooms. The front bedroom door was wedged open, while the door to the back bedroom was wedged closed. Contrary to expectations and despite the relatively small fire load, analysis and hazard calculations show permeation of toxic fire gases throughout the property with lethal concentrations of effluent being measured at each sampling point. A generally poor state of repair and missing carpets in the upper story contributed to a high degree of gas and smoke permeation. The available egress time was calculated as the time before the main escape route became impassable. Given known human responses to fire, such an incident could have caused fatalities to sleeping or otherwise immobile occupants.  相似文献
