Artifacts Caused by Leaf-Cutting Ants of the Genus Atta (Hymenoptera: Formicidae): Postmortem Bite Injuries and the Tearing of Clothes

Ants are one of the first insects to find an exposed cadaver and can be present during all stages of decomposition. Although these organisms are not commonly used in postmortem interval estimates, they are to be taken into account on criminal investigations involving human corpses, since they can leave bite marks that can be mistaken for antemortem or perimortem injuries, which could be misleading when ascertaining the occurrence of abuse or physical altercation during a crime. A few studies report the action of ants on human cadavers and even though leaf-cutting ants of the genus Atta are frequently encountered in succession studies that use animal carcasses, there are no records of these fungus-growing species on human corpses. Atta is a genus restricted to the New World, ranging from northern Argentina to southern United States and acts as one of the most conspicuous neotropical herbivores. In this study, we report three cases of violent death that illustrate the impact of ants, especially those of the genus Atta, in a forensic setting. We compare the patterns displayed by postmortem bite injuries caused by leaf-cutter ants and other common species with less robust mandibles. We also present the capability of Atta ants to create artifacts by cutting victim’s clothes in a crime scene, contributing to the knowledge of ant-mediated confounding factors in crime scene investigation.     

The Grecian horse: does immigration lead to the deterioration of American institutions?

Concerns about the institutional impact of immigration, particularly in the United States, are not new. We can trace them back to Benjamin Franklin, Thomas Jefferson, and Alexander Hamilton. More recently, in response to a literature that questions the desirability of current immigration restrictions, Borjas (J Econ Lit 53:961–974, 2015) speculates that immigrants coming from countries with poor institutions could reduce substantially the institutional quality in the United States to a point where it could negate all economic gains associated with immigration in terms of GDP and income. Using the Economic Freedom of North America index since 1980, we find no evidence to corroborate Borjas’s concerns. However, we find mixed evidence that immigration increases minimum wages and union density.     

Trajectories of Social and Emotional Competencies according to Cyberbullying Roles: A Longitudinal Multilevel Analysis

Current cyberbullying literature lacks longitudinal studies clarifying its predictors and consequences. This 1-year longitudinal study investigated how social and emotional competencies develop according to Portuguese middle school students’ involvement in cyberbullying, and whether class size influences this relationship. There were 455 participants (M_age?=?12.58; SD?=?0.94; 46% girls), and data collection through self-reports took place in three different moments during 12 months. The results showed that students involved in cyberbullying in any role displayed negative trajectories during 1 year in self-control and social awareness, while victims and bully-victims displayed a more pronounced decrease in self-esteem and relationship skills during the same period. Additionally, girls displayed higher initial social awareness levels, while larger classes were associated with higher levels of self-control and responsible decision making. These results supported the importance of conducting longitudinal research and using a multilevel approach to address this topic.     

French ‘officiers ministériels’: autonomy of the legal professions,protection of their market and an ambivalent relationship with the state

The occupational status of officier ministériel which applies to auctioneers (commissaires-priseurs), bailiffs (huissiers de justice) and notaries (notaires) goes back to the Ancien Régime and continues to embody a remarkable example of a typically French model for structuring professions: officiers ministériels are both the repositories of a slice of public authority and the self-employed members of a profession. This unique status is still upheld by the French state which determines the conditions for entering as well as exercising these professions (granting of monopolies, setting certain fees and competitive practices, etc.). But after having survived intact for so long, the construction of a legal and judicial European space in the second half of the twentieth century has accelerated the transformation of certain professional groups reflected in an entrepreneurial approach and changing business models. Professional representative bodies have also largely contributed to these changes by managing to thwart programmes and political decisions through a wide range of development or resistance strategies.     

Dignity Takings and Dispossession in Israel

This article examines the concept of dignity takings, as developed by Bernadette Atuahene, and its applicability to the Israeli situation, focusing on takings from the Arab‐Palestinian minority in Israel. Although I find dignity takings a valuable concept, as it emphasizes the interconnections between land dispossession and the denial of human dignity, I offer some qualifications and suggestions. I then examine the applicability of the concept to the dispossession of Arabs/Palestinians in Israel through two case studies: one, a close reading of the (in)famous Ikrit villagers' dispossession; the other, an examination of the dispossession of Negev (southern Israel) Bedouin citizens of Israel, which takes place, not unlike terra nullius, simultaneously with a denial of this very taking. The article concludes that with some modifications, the concept of dignity taking applies to the situation of Arab/Palestinian citizens of Israel.     

Integration of Pore Features into the Evaluation of Fingerprint Evidence*

Fingerprint practitioners rely on level 3 features to make decisions in relation to the source of an unknown friction ridge skin impression. This research proposes to assess the strength of evidence associated with pores when shown in (dis)agreement between a mark and a reference print. Based upon an algorithm designed to automatically detect pores, a metric is defined in order to compare different impressions. From this metric, the weight of the findings is quantified using a likelihood ratio. The results obtained on four configurations and 54 donors show the significant contribution of the pore features and translate into statistical terms what latent fingerprint examiners have developed holistically through experience. The system provides LRs that are indicative of the true state under both the prosecution and the defense propositions. Not only such a system brings transparency regarding the weight to assign to such features, but also forces a discussion in relation to the risks of such a model to mislead.     

Self‐Embedding Behavior in Adults: A Report of Two Cases and a Systematic Review

Self‐embedding behavior (SEB) is the repeated insertion of sharp objects, such as needles or pins, into the soft tissues of abdomen, limbs, and other body parts. In this study, two cases of SEB were reported and the scientific worldwide literature reviewed. Thirty‐two cases of SEB were identified through systematic searches in the main bibliographic databases. Mean age was 35 years (SD = 8.97). Just over two‐thirds of the patients were female. Although the number of embedded objects could be as high as 200, major clinical and surgical complications were uncommon and mortality was null. Patients with SEB presented three major diagnoses: psychotic (25%), personality (21.9%), and factitious (28.1%) disorders. The practice of SEB largely went undetected as the patients themselves did not bring it to the attention of family members or physicians and usually denied they have engaged in SEB. A high level of suspicion is required to avoid a missed diagnosis.
