Intraobserver error (INTRA‐OE) is the difference between repeated measurements of the same variable made by the same observer. The objective of this work was to evaluate INTRA‐OE from 3D landmarks registered with a Microscribe, in different datasets: (A) the 3D coordinates, (B) linear measurements calculated from A, and (C) the six‐first principal component axes. INTRA‐OE was analyzed by digitizing 42 landmarks from 23 skulls in three events two weeks apart from each other. Systematic error was tested through repeated measures ANOVA (ANOVA‐RM), while random error through intraclass correlation coefficient. Results showed that the largest differences between the three observations were found in the first dataset. Some anatomical points like nasion, ectoconchion, temporosphenoparietal, asterion, and temporomandibular presented the highest INTRA‐OE. In the second dataset, local distances had higher INTRA‐OE than global distances while the third dataset showed the lowest INTRA‐OE. 相似文献

BackgroundA seasonal variation in violence and suicidal behaviour has been reported in several studies with partially congruent results. Most of forensic psychiatric patients have a history of severe violent behaviour that often continues in spite of regular treatment. In the forensic psychiatric hospital environment aggressive and suicidal acts are often sudden and unpredictable. For reasons of safety, rapid and intensive coercive measures, such as seclusion and restraint, are necessary in the treatment of such patients.ObjectiveTo examine whether these involuntary seclusions have a seasonal pattern, possibly similar than the reported seasonal variation in violence and suicidal behaviour. By investigating the possibility of a seasonal variation of seclusion incidents from violent and suicidal acts, it may become possible to improve the management of forensic psychiatric patients.MethodsThe hospital files of all secluded patients at Niuvanniemi Hospital from 1 January 1996 to 31 December 2002 were examined. In total, 385 patients (324 male and 61 female) were identified as being secluded at least once in 1930 different incidents (1476 from male and 454 from female patients). Seasonal decomposition and linear regression with dummy month variables were used to examine the possibility of annual variations for seclusions.ResultsThe seasonal variation of involuntary seclusion incidents was statistically significant. According to the linear regression model, most of the seclusion incidents, affecting many different patients, began in July and August, and were concentrated throughout the fall until November. The sum of all seclusion days was lowest in January and highest between July and November (difference + 31% to + 37%).ConclusionsThese findings are mainly in agreement with results from other studies on seasonal variation and violent behaviour. The allocation of staff for late summer and fall might enhance the management of forensic psychiatric patients, thus leading to possible decreases in seclusion incidents. The factors affecting violent, aggressive and suicidal behaviours are complex and more investigation is needed to understand, identify, intervene and effectively reduce such behaviours. 相似文献

Aggressive or paradoxical behaviour may reflect an organic dementia. The most frequent is Alzheimer's disease, which results from an abnormal structural conformation of tubulin-associated protein (tau) and beta-amyloid protein that, respectively, aggregate in certain neurons as intracellular neurofibrillary tangles (NFTs) and in the extracellular environment as senile plaques.These lesions progress in the brain tissue according to the stages described by Braak and Braak. Staging of neurofibrillary pathology has proven anatomical and clinical correlation, which can be used in a medico-legal procedure. We report two cases demonstrating discrepancies between anatomical and clinical features, which should encourage medical expert to prudence when interpreting neuropathological reports. 相似文献

Grid based sentencing guidelines, composed of offense seriousness and offender criminal history axis, have become a staple of US sentencing in recent decades. As such, extensive research explores whether they reduce extralegal sentence disparity. However, to date, no study has examined whether extralegal disparity is present in how either axis of guideline sentencing are constructed. Using federal sentencing commission data along with both single and multi-level analyses, this research explores the legal and extralegal factors that predict one of these key grid axes: the offense seriousness score. The results call into question not only some assumptions underlying guideline sentencing but also recent analytical strategies for assessing sentencing outcomes in guideline systems. 相似文献

Recent developments on postmortem interval estimation (PMI) take an advantage of the autolysis process, pointing out to the analysis of the expression of apoptosis and autophagy genes towards this purpose. Oxidative stress plays a role in this signaling as a regulatory mechanism and/or as a consequence of cell death. Additionally, melatonin has been implicated on apoptosis and autophagy signaling, making melatonin a suitable target for PMI determination. The aim of this study was to investigate the early PMI through the analysis of the expression of autophagy genes as well as oxidative stress and melatonin receptor. Our results demonstrated a rapidly increased on the expression of autophagy genes according to the expected sequence of events, then a marked decrease in this expression, matched with the switch to the apoptosis signaling. These results revealed potential candidates to analyze the PMI in the first hours of death, helping to estimate the time-since-death. 相似文献

Austerity policies across European countries have encountered diverse forms of public protest and resistance. In Sweden, we have seen the emergence of a number of networks and organizations which take care workers’ professional identity as their point of departure. These networks and organizations stress the impossibility of being professional care workers in slimmed-down, neoliberal organizations. Parallel to this, and sometimes embedded into one another, female-dominated professions (e.g. social workers, nurses, doctors, and teachers) have been engaged in opposing restrictive refugee policies. This article analyses how care workers in an emergency room in Malmö mobilized against a visit by Jimmie Åkesson, leader of the right-wing, xenophobic Sweden Democrats. The article explores how workers used a gendered discourse of care and professionalism to argue that their actions were consistent with both organizational culture and their professional ethics. The article shows how, by defending their professional role of providing quality care to all in need, workers challenge both austerity and racist policies, which both impose restrictions on who has the right to care. Theoretically, the article explores how the politicization of care creates spaces of resistance, to critique both austerity policies and exclusionary understandings of national belonging. The study stresses the importance of identifying emerging forms of collective resistance among care workers at the intersection of the struggles against austerity and right-wing xenophobic parties. 相似文献
