Lacan’s psychoanalytical theory is of interest to legal theorists for a number of reasons. In particular, the concept of the Name of the Father allows a sophisticated theorisation of law and legal institutions. However, the Name of the Father was not Lacan’s only theory of law. In his final Seminars, Lacan developed a second and fundamentally different theory of law: the sinthome. By drawing upon Roberto Harari’s commentary on Lacan’s concept of the sinthome, the sinthome can be investigated in terms of topology, chaos, and morphogenetic theories. This can allow a complex theory of the sinthome to be put forward as real, immanent, emergent ordering through the de-limiting of singularities. From this a concept of Sinthome Law can be developed as a novel concept of law, and as a potential way to understand some contemporary problematics in law. The example of the emerging law on electronic signatures is introduced to indicate this.  相似文献

Workers' compensation provides cash benefits and medical care to employees who are injured on the job and survivor benefits to the dependents of workers whose deaths result from work-related incidents. Workers' compensation programs in the 50 states and the District of Columbia and federal programs together paid $56.0 billion in medical and cash benefits in 2004, an increase of 2.3 percent over 2003 payments. Of the total, $26.1 billion was for medical care and $29.9 billion was for cash benefits. Employers' costs for workers' compensation in 2004 were $87.4 billion, an increase of 7.0 percent over 2003 spending. Workers' compensation programs and spending vary greatly from state to state. As a source of support for disabled workers, workers' compensation is currently surpassed in size only by Social Security Disability Insurance (DI), which covers impairments of any cause that are significant, long-term impediments to work. Although most recipients of workers' compensation recover and return to work, those with lasting impairments may become eligible for DI benefits, subject to an offset to avoid excessive wage replacement from both programs.  相似文献

Abstract: This study provides forensic search teams with systematic geophysical monitoring data over simulated clandestine graves for comparison to active cases. Simulated “wrapped” and “naked” burials were created. Multigeophysical surveys were collected over a 3‐year monitoring period. Bulk ground resistivity, electrical resistivity imaging, multifrequency ground‐penetrating radar (GPR), and grave and background “soil‐water” conductivity data were collected. Resistivity surveys revealed the naked burial had consistently low‐resistivity anomalies, whereas the wrapped burial had small, varying high‐resistivity anomalies. GPR 110‐ to 900‐MHz frequency surveys showed the wrapped burial could be detected throughout, with the “naked” burial mostly resolved. Two hundred and twenty‐five megahertz frequency GPR data were optimal. “Soil‐water” analyses showed rapidly increasing (year 1), slowly increasing (year 2), and decreasing (year 3) conductivity values. Results suggest resistivity and GPR surveys should be collected if target “wrapping” is unknown, with winter to spring surveys optimal. Resistivity surveys should be collected in clay‐rich soils.  相似文献

A 2010 UK police search for a clandestine burial highlighted the need for more information and quantitative data to aid coastal beach searches. This study aimed to address this by establishing relevant forensic search methodologies to aid the search for clandestine coastal burial sites, using the North West English coastline as a search area. A set of parameters were established, including criteria such as tidal range, proximity to vehicular access points and distance from inhabited areas, which may inform forensic searches by prioritising likely locations of clandestine burials. Three prioritised coastal locations were subsequently identified: (1) coastal dunes at Formby, (2) coastal dunes and (3) beach foreshore at Southport, all sites part of the Liverpool City Region in the United Kingdom. At all locations, simulated clandestine graves were hand-dug by spades into which a naked adult-sized, metal-jointed fiberglass mannequin was buried at 0.5 m below ground level. Trial geophysical surveys were then undertaken with the aim of identifying the optimal geophysical instrumentation and technique to deploy in such environments. GPR data showed 450 MHz frequency antennae to be optimal, with significantly poor data obtained from the foreshore area due to saline seawater. Electrical resistivity and magnetic susceptibility surveys were successful in coastal environments in target detection (albeit not in non-vegetated sand dunes), with resistivity fixed-offset configurations deemed optimal. The latter survey successes may be due to the recent disturbed 'grave' rather than the target, which itself is of interest in terms of identifying the most recent clandestine burials.  相似文献

Objectives

The purpose of this study is twofold. First, this study assesses the extent to which self-control and maternal attachment mutually influence one another. Second, it investigates whether this process continues to occur during adolescence. To date, studies of the etiology of self-control have yet to adequately address these issues, despite the fact that a number of theoretical perspectives emphasize the reciprocal nature of the parent-child relationship.

Methods

The current study seeks to shed light on these issues by examining the relationship between self-control and maternal attachment using structural equation modeling for eight waves of data spanning a period of time that encompasses early childhood through middle adolescence.

Results

The results yield two findings bearing on the adequacy of Gottfredson and Hirschi??s model of self-control development. First, measures of self-control and maternal attachment were found to mutually influence one another during childhood. Second, these effects were reduced to nonsignificance during adolescence.

Conclusions

This study finds that self-control emerges during childhood in a complex manner in which it both shapes and is shaped by parental attachment.  相似文献

Advocates, clinicians, policy makers, and survivors frequently cite intimate partner violence (IPV) as an immediate cause of or precursor to housing problems. Research has indicated an association between homelessness and IPV, yet few studies examine IPV and housing instability. Housing instability differs from homelessness, in that someone experiencing housing instability may currently have a place to live but faces difficulties with maintaining the residence. We present baseline findings from a longitudinal cohort study of 278 female IPV survivors with housing as a primary concern. Our analysis indicates the greater the number of housing instability risk factors (e.g., eviction notice, problems with landlord, moving multiple times), the more likely the abused woman reported symptoms consistent with PTSD (p < .001), depression (p < .001), reduced quality of life (p < .001), increased work/school absence (OR = 1.28, p < .004), and increased hospital/emergency department use (OR = 1.22, p < .001). These outcomes persist even when controlling for the level of danger in the abusive relationship and for survivors' drug and alcohol use. Importantly, both housing instability and danger level had stronger associations with negative health outcomes than other factors such as age, alcohol, and drug use; both make unique contributions to negative health outcomes and could contribute in different ways. Housing instability is an important and understudied social determinant of health for IPV survivors. These findings begin to address the literature gap on the relationship between housing instability, IPV, and survivors' health, employment, and utilization of medical care services.  相似文献

A nonrandom national U.S. sample of 946 homicide crime scenes--supplied by the FBI Behavioral Science Unit for purposes of research--was studied to delineate the prevalence, types, levels, and motives for staging in domestic, nonserial sexual, serial sexual, and general felony homicides. Stagers were found to be a relatively small group who employ a variety of methods to alter the crime scene in an attempt to redirect the investigation away from themselves as logical suspects. Results also suggest that different types of homicides have different staging rates based primarily on the relationship (or connection) between offender and victim. Implications for investigations and understanding this type of crime scene behavior are discussed.  相似文献

Police witness intelligence stated a murdered adult male “Fred” had been vertically buried in wooded hilly terrain 30 years ago in the Midlands, U.K. Conventional search methods were unsuccessful; therefore, the police requested a geophysical investigation to be undertaken to determine whether “Fred” could be detected. A multiphased geophysical approach was conducted, using bulk ground conductivity and metal detectors, then follow‐up magnetics and ground penetrating radar (GPR) survey profiles on electromagnetic (EM) anomalous areas. A tight grid pattern was used to account for the reduced target size. Relatively high‐resolution EM and GPR techniques were determined optimal for this terrain and sandy soil. Geophysical anomalies were identified and the most promising intrusively investigated, and this was found to be a large boulder and tree roots. Study implications suggest careful multiphase geophysical surveys are best practice and give confidence in cold case searches. This study yielded a no‐body result, effectively saving police time and costs from further investigations.  相似文献

In homicide investigations, it is critically important that postmortem interval and postburial interval (PBI) of buried victims are determined accurately. However, clandestine graves can be difficult to locate; and the detection rates for a variety of search methods (ranging from simple ground probing through to remote imaging and near‐surface geophysics) can be very low. In this study, simulated graves of homicide victims were emplaced in three sites with contrasting soil types, bedrock, and depositional environments. The long‐term monthly in situ monitoring of grave soil water revealed rapid increases in conductivity up to 2 years after burial, with the longest study evidencing declining values to background levels after 4.25 years. Results were corrected for site temperatures and rainfall to produce generic models of fluid conductivity as a function of time. The research suggests soilwater conductivity can give reliable PBI estimates for clandestine burials and therefore be used as a grave detection method.  相似文献
