Important work has been done to measure legislative effectiveness in the U.S. Congress and to explain the individual characteristics that drive it. Much less attention, however, has been devoted to study the extent to which legislative effectiveness depends on the legislators' social connections. We address this issue with a new model of legislative effectiveness that formalizes the role of social connections, and we test its predictions using the network of cosponsorship links in the 109th–113th Congresses. We propose a new empirical strategy that addresses network endogeneity by implementing a two-step Heckman correction based on an original instrument: the legislators' alumni connections. We find that social connections are a significant determinant of legislative effectiveness. We also study the influence of legislators' characteristics in shaping the network effects. In doing so, we provide new insights into how social connectedness interacts with factors such as seniority, partisanship, and legislative leadership in determining legislators' effectiveness. 相似文献

ABSTRACTThis paper offers some reflections on the possible consequences of Brexit for legal education in Scotland. Scotland’s small and distinctive legal system is bolstered by devolved legislative powers and characterised by a tradition of openness to external influences. Scotland’s legal system and relatedly, its legal education system, will be poorer for Brexit. That said, this paper argues that the features and traditions of the legal system and legal higher education system in Scotland make them well placed (and perhaps better placed than those in the other domestic jurisdictions) to resist such dampening pressures and indeed to embrace EU legacies and other European and international influences. 相似文献

The discovery of mummified bodies in domestic settings is not unusual in the medico‐legal context. It is often a marker of social isolation, even in our urban modern society, and usually occurs among elderly people living alone or in precarious conditions. However, bereaved subjects can sometimes be found managing their grief by deliberately keeping the corpses of their loved ones at home. Investigation of these atypical cases can be challenging and often requires a multidisciplinary effort by different forensic specialists. We report two cases of people who lived for several months with the mummified remains of a relative. In both cases, the judge ordered a forensic psychiatry assessment of the survivors’ competency and the reasons for this peculiar behavior, which is regarded as abnormal in our society. Case 1 describes a shared psychosis, which developed out of a condition of extreme seclusion of the entire family. Case 2 shows that even a mild personality disorder on which a series of traumatic events operates can trigger psychotic decompensation, causing extreme denial of the reality of death. The analysis of these cases contributes to our knowledge of the scantly studied phenomenon of “Living with the Dead” and raises questions about the psychopathology behind it. It is useful to identify subjects who are more prone to developing this “deviant” behavior, in order to distinguish people with mental illness from those who merely want to profit from the death of a loved one. 相似文献

Ausgehend von den Reaktionen auf zwei ähnliche Ereignisse – die "Massaker" in Genf und Zürich im Jahre 1932 – formuliert der Artikel Hypothesen über die Erfolgsbedingungen eines bürgerrechtsorientierten Diskurses in der Öffentlichkeit. In Genf konnte sich dieser Diskurs hegemonial ausbreiten, während sich in Zürich ein Law-and-Order Diskurs durchgesetzt hat. Die Ausrichtung der Diskurse wird anhand eines politischen Modells erklärt. Die diskursiven Strategien der politischen Parteien richten sich nach a) den Allianzen mit sozialen Bewegungen, b) ihrer Position im politischen System (Regierung oder Opposition) und c) dem Wahlprozess, welchem eine Validierungsfunktion der diskursiven Optionen zukommt. Die Autoren argumentieren, dass die diskursiven Strategien der 1930er Jahre zu wichtigen und bindenden symbolischen Ressourcen für die politischen Akteure in den 70er Jahren wurden, als die Auseinandersetzung um die öffentliche Ordnung mit dem Aufkommen der neuen sozialen Bewegungen wieder auf der politischen Agenda erschien. 相似文献

Eosinophilic myocarditis (EM) is a rare and potentially fatal form of myocarditis characterized by infiltration of the myocardium with eosinophil leukocytes, often accompanied by eosinophilia. Although the exact underlying cause remains unknown, it has been shown to be associated with hypersensitivity reactions, immune-mediated disorders, infections, or cancer. Due to the differences in symptomatology, it is often diagnosed by postmortem histopathological examination. We aimed to retrospectively examine the histopathological findings of rare cases of EM and to detect accompanying cardiac and other organ pathologies. The histopathological findings of the cases that underwent autopsies between 2012 and 2020 and were diagnosed with EM were assessed. Demographic features, symptoms, causes of death, macroscopical findings at autopsy, toxicologic and microbiological analysis results, accompanying cardiac pathologies, and histopathological findings in other organs were evaluated. Myocarditis was detected on histopathologic examination in 558 (1.1%) of 49,612 forensic autopsies. There were 12 (2.3%) EM cases. There were nine males and four females. The mean age was 42.3 (3–83) years. Heart weights ranged from 82 to 564 g. The most common finding on macroscopic examination was the mottled discoloration and scarring in the myocardium. Microscopic examination revealed perivascular and interstitial infiltration of eosinophils in all of the cases accompanied by myocyte necrosis in four of them. EM was reported as the cause of death in four cases. EM remains a challenging heart disease with its obscure etiopathogenesis and varying clinical presentation and a rare entity diagnosed by postmortem histopathological examination in sudden and unexpected deaths. 相似文献

Deaths occurring due to rattlesnake envenomization are extremely rare and must be thoroughly investigated in the same manner as any other type of death. Our research presents the case of an adult white male who suffered a fatal timber rattlesnake (Crotalus horridus) envenomation in northwest Florida in 2018. Blood samples were taken from the decedent's heart and vasculature of the chest and sent for serum proteomic analysis. Serum proteomic analysis was utilized in order to identify proteins from timber rattlesnake (C. horridus) found within the victim's blood. The confirmation of the presence of timber rattlesnake venom within the victim's blood allows the forensic pathologist to determine the cause of death most accurately and likewise, assists with the manner of death determination. Blood samples were separated into two groups: one with the abundant endogenous proteins depleted to facilitate detection of lower abundant proteins and one undepleted. In the depleted sample, a total of 712 proteins were identified, with 47 of the proteins (6.6%) occurring originating from timber rattlesnake (C. horridus). Likewise, a total of 742 proteins were identified in the undepleted sample, with 52 of the proteins (7.0%) occurring in timber rattlesnake (C. horridus). No timber rattlesnake (C. horridus) proteins were found in control human serum. 相似文献

As the overdose epidemic overwhelmed medicolegal death investigation offices and toxicology laboratories, the King County Medical Examiner's Office responded with “real-time” fatal overdose surveillance to expedite death certification and information dissemination through assembling a team including a dedicated medicolegal death investigator, an information coordinator, and student interns. In-house testing of blood, urine, and drug evidence from scenes was performed using equipment and supplies purchased for surveillance. Collaboration with state laboratories allowed validation. Applied forensic epidemiology accelerated data dissemination. From 2010 to 2022, the epidemic claimed 5815 lives in King County; the last 4 years accounted for 47% of those deaths. After initiating the surveillance project, in-house testing was performed on blood from 2836 decedents, urine from 2807, and 4238 drug evidence items from 1775 death scenes. Time to complete death certificates decreased from weeks to months to hours to days. Overdose-specific information was distributed weekly to a network of law enforcement and public health agencies. As the surveillance project tracked the epidemic, fentanyl and methamphetamine became dominant and were associated with other indicators of social deterioration. In 2022, fentanyl was involved in 68% of 1021 overdose deaths. Homeless deaths increased sixfold; in 2022, 67% of 311 homeless deaths were due to overdose; fentanyl was involved in 49% and methamphetamine in 44%. Homicides increased 250%; in 2021, methamphetamine was positive in 35% of 149 homicides. The results are relevant to the value of rapid surveillance, its impact on standard operations, selection of cases requiring autopsy, and collaboration with other agencies in overdose prevention. 相似文献
