The aim of this paper is to explore the effects of spillovers driven by competition and forward and backward linkages between foreign firms and Italian firms. We adopt the firm dynamics framework, which allows us to test the impact of foreign firms’ activity on the probability that local firms will exit. The empirical analysis relies on continuous survival models (Cox proportional hazard models) and uses a representative firm level database from the period of 2002–2010 with data concerning more than 4,000 Italian manufacturing firms. Our estimates regarding the whole sample show that horizontal and vertical linkages have no impact on firm survival. To further test this finding, we perform a more disaggregated analysis that allows for heterogeneity across firms and sectors. We obtain evidence that the effects of FDI spillovers on firm survival follow specific patterns at both the intra- and inter-industry levels based on differences in productivity between Italian firms and foreign firms and on the technological intensity of the industry. Foreign firms’ activity reduces the exit probability of competitors and of downstream local customers (through forward linkages) with low productivity gap but has no impact on high productivity gap firms. Firms in high technology intensive sectors do not benefit from horizontal FDI while in low and medium technology sectors they do. Differences in absorptive capacity may explain these results. However, we also find that vertical linkages with foreign firms in the upstream supplying industries spur firm duration in medium and high tech sectors.  相似文献

Children's rights to participate in legal processes concerning them have been a key policy issue for the Scandinavian legislators during recent decades. From the 1980s, there have been frequent amendments to the law to secure the position of the child. Despite numerous provisions stating the right of the child to express his or her views and for these to be considered before decisions are taken, there are continuing obstacles to full recognition of children as legal subjects. Too often children's voices are not heard or not heeded. This article explores the reasons for this and argues that the ambition to promote equal parenthood is one reason for the failure to give the child's views real impact on decision-making in matters concerning children.  相似文献

ABSTRACT

In view of a crisis of liberal universalism peace research must reflect on how it is perceived, how peace is constructed in other places and how it can cope with diversity in ordering and peacebuilding. This Special Issue is an attempt to search starting points for peace research in and with Central Eurasia. The introductory concept clears a path through current research questions, normative problems and barriers of knowledge production. Considering ethnographic methodologies, it starts from the local everyday and takes an interest in how actors and institutions in concrete places and multiple socio-spatial configurations navigate conflict and peace.  相似文献

ABSTRACT

This article reports the findings of a small-scale qualitative study exploring the experiences of autistic adults who have had experience of the family justice system. While participants related some positive elements to their experiences, in particular with regard to the willingness of professionals to try to learn more about their clients’ needs, the overall picture showed significant concerns. The reports given showed significant misunderstandings about autism, and a system which struggled to make appropriate adjustments which would allow autistic court users to have access to justice on an equivalent basis to non-autistic litigants. This situation stands in contrast to the position regarding other disabilities in the Family Justice System, but also to the relatively greater level of provision for autistic people within the Criminal Justice System. Based on participants’ experiences and existing good practice in other areas, we make recommendations that could be adopted by the Family Court and practitioners.  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

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

Research has demonstrated that paternal incarceration is associated with lower levels of educational involvement among fathers and primary caregivers, but little is known regarding caregiver educational involvement when mothers have been incarcerated. In this study, we present the first analysis of variation in school- and home-based educational involvement by maternal incarceration history, pairing survey and interview data to connect macro-level group differences with micro-level narratives of mothers’ involvement in their children's education. Our survey data demonstrate that children of ever-incarcerated mothers experience increased school-based educational involvement by their primary caregivers, regardless of whether the caregiver is the mother herself. Our interview data point to compensatory parenting as a key motivating factor in educational involvement, wherein a caregiver endeavors to “make up for” the child's history of maternal incarceration. Findings add to the literature demonstrating maternal incarceration as a distinct experience from both paternal incarceration and material disadvantage alone, and they suggest the need to explore the role of schools as potential points of productive institutional involvement for mothers with an incarceration history.  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
