Replica casting of the skull base

A new technique is described of obtaining a replica cast of the human skull base by making an epoxy resin case from a silicone rubber mould of the skull base. The replica provides an accurate and permanent record of the shape and dimensions of the base of the cranial cavity, together with the location and extent of any fractures of the skull. The method gives a good correlation between these characteristics and the type and extent of brain damage.     

Economies of scale and Brazilian local government expenditure: evidence from the State of Paraná

ABSTRACT

Controversy surrounds local government reform, particularly efforts directed at reducing the number of local authorities to secure economies of scale. We examine whether economies of scale exist in local government outlays by analysing the expenditure of 398 municipalities for the Brazilian state of Paraná using a 16-year panel dataset covering the period 2002–2017. We find evidence that municipal expenditure is characterised by substantial scale economies. However, given the strong correlation between population size and population density, it is important to ascertain whether the influence of population size on municipal expenditure is due to variations in population density or not. When local government areas are divided into sub-groups based on population density, evidence of scale economies remains with the majority of councils operating below optimal size. Municipal consolidations may thus lead to lower per capita expenditure.     

Homicide by a Forensic Female Sample in Brazil: A Preliminary Study

The objective of the study was to evaluate the mental status of all women (n = 14) who were acquitted by reason of insanity of charges of murder or attempted murder and committed to a forensic psychiatric hospital in the state of Rio de Janeiro, Brazil. All cases were retrospectively examined, including medical files, technical records, and forensic experts' official reports. A conclusive psychiatric diagnosis was established using the Structured Clinical Interview for DSM‐IV Axis I and II Disorders and clinical and forensic records. The most common diagnosis was schizophrenia/schizoaffective disorders (n = 8; 57.3%). Most victims (n = 12; 75%) were close relatives of the patients. We found that 43% (n = 6) of the patients had a previous history of violent behavior. According to the initial psychiatric forensic evaluation, 5 patients (35.7%) had psychotic symptoms. It is expected that a growing understanding of motivational factors underlying homicidal behavior in mentally disturbed female offenders may further the implementation of effective preventive and therapeutic interventions.     

The Multiple Bases of Social Return Platforms: Evidence of a Brazilian Initiative

The literature on platforms emphasizes the balance between supply and demand as precursors to network expansion, strategy development and strategy sustainability. This study questions this logic through the exploratory approach of a public platform based on social returns. Results demonstrate that when an institutional force supports a platform concerned with diffuse and collective interests, it is possible that the strategy could sustain and develop without the balance of its forces. The study contributes to the strategic platform literature by pointing out the distinct aspects of social platforms and underlining the support generated by institutions.     

Filicide, attempted filicide, and psychotic disorders

The objective of the study was to describe and discuss the cases of two women who faced criminal charges, one for attempting to murder her three children and the other for killing her 1-year-old boy. After a forensic psychiatric assessment of their level of criminal responsibility, these patients were considered not guilty by reason of insanity and were committed to forensic mental hospitals. These two patients received a diagnosis of paranoid schizophrenia, according to the DSM-IV-TR criteria. In both cases, psychotic symptoms were present before the manifestation of violent behavior, in the form of persecutory delusions, auditory hallucinations, and pathological impulsivity. The investigation into cases of filicide may contribute powerfully to expand our understanding of motivational factors underlying this phenomenon and enhance the odds for effective prevention.
