Forensic age estimation is an important element of anthropological research, as it produces one of the primary sources of data that researchers use to establish the identity of a person living or the identity of unknown bodily remains. The aim of this study was to determine if the chronology of third molar mineralization could be an accurate indicator of estimated age in a sample Brazilian population. If so, mineralization could determine the probability of an individual being 18 years or older. The study evaluated 407 panoramic radiographs of males and females from the past 5 years in order to assess the mineralization status of the mandibular third molars. The evaluation was carried out using an adaptation of Demirjian's system. The results indicated a strong correlation between chronological age and the mineralization of the mandibular third molars. The results indicated that modern Brazilian generation tends to demonstrate an earlier mandibular third molar mineralization than older Brazilian generation and people of other nationalities. Males reached developmental stages slightly earlier than females, but statistically significant differences between the sex were not found. The probability that an individual with third molar mineralization stage H had reached an age of 18 years or older was 96.8-98.6% for males and females, respectively. 相似文献

In multi-tiered organizations, individuals can engage in unproductive rent-seeking activities both within and between the divisions of the organization. Nevertheless, a multi-tiered organizational structure can induce efficiency gains by decreasing rent-seeking. We present a model of production and simultaneous internal and external rent-seeking, assuming a logistic contest success function. In equilibrium, there is generically either internal or external rent-seeking, but not both. A multi-tiered organization leads to less rent-seeking and higher welfare, even though the production technology gives no reason for any specific organizational structure. Our findings constitute a new efficiency rationale for multi-tiered organizations. 相似文献

The issue of international terrorism has figured frequently in recent political debates and media coverage. In the present
paper, we explore the question of how the salience of the concept of international terrorism affects the system-justifying
tendencies of public opinion. On the basis of Terror Management Theory and System Justification Theory it was hypothesized
that terrorism salience would lead to increased system justification. Four experiments with student and non-student adult
samples support the hypothesis, yielding a medium-sized average effect of d = 0.47. Across variations in the intensity of focal death-related thoughts, the effect was not subject to boundary conditions
typical of mortality salience effects. Social and political psychological implications are discussed.

The longstanding connection between criminological theory, research and the design and delivery of criminal justice policy
has been challenged in the last 3 decades by a variety of constraints such as the rise of neoconservative attitudes, symbolic
public discourses about crime, and the proliferation of capture, monitor, and detect strategies brought about by technological
innovation. Building on Kevin Haggerty’s (2004. Displaced expertise: three constraints on the policy-relevance of criminological
thought. Theoretical Criminology, 8(2), 211–231.) exploration of the external factors that challenge the transition from criminological theory to criminal justice
policy and practice, this paper considers internal challenges that may also be relevant. By examining two recent critical
criminological orientating strategies, namely left realism and constitutive criminology, the paper concludes by suggesting
that an integrated perspective which draws strengths from each of these approaches could assist critical criminologists to
better influence policy in the future.
