Bone Mineral Change During Experimental Calcination: An X‐ray Diffraction Study

The effects of calcination (400–1200°C) on pig bones have been studied using powder X‐ray diffraction (XRD) and secondary modifications, such as color change and weight loss. The characterisation by powder XRD confirmed the presence of the crystalline phase of hydroxyapatite, and comparison of the results obtained at different temperatures suggested that at 650°C, all the organic components and carbonate substitutions were completely removed. Accordingly, these samples were white. In addition, the crystallinity degree and the crystallite size progressively increased with the calcination temperature until 650°C, remaining stable until 1200°C. Below 650°C, bone samples presented organic compounds, resulting in background noise in the diffractogram and gray or black color. In addition, impurities in the lattice correspond to low crystallite sizes.     

Provoking a civil war

Nondemocratic governments under the rule of weak institutions use repression against the opposition to remain in power. Repression both muffles the opposition’s voice and strengthens the government’s supporters. Nevertheless, when repression becomes strong enough, it becomes intolerable to its victims who revolt and initiate a civil war. The government is aware of the mechanism and determines the level of repression accordingly. This paper studies the circumstances in which the ruler’s best alternative is to intensify repression to the point of provoking civil war. Although the model is abstract, its implications are discussed using the recent civil war in the Ivory Coast as a case study.     

Determined to Die! Ability to Act Following Multiple Self‐inflicted Gunshot Wounds to the Head. The Cook County Office of Medical Examiner Experience (2005–2012) and Review of Literature

Cases of multiple (considered 2+) self‐inflicted gunshot wounds are a rarity and require careful examination of the scene of occurrence; thorough consideration of the decedent's psychiatric, medical, and social histories; and accurate postmortem documentation of the gunshot wounds. We present a series of four cases of multiple self‐inflicted gunshot wounds to the head from the Cook County Medical Examiner's Office between 2005 and 2012 including the first case report of suicide involving eight gunshot wounds to the head. In addition, a review of the literature concerning multiple self‐inflicted gunshot wounds to the head is performed. The majority of reported cases document two gunshot entrance wound defects. Temporal regions are the most common affected regions (especially the right and left temples). Determining the capability to act following a gunshot wound to the head is necessary in crime scene reconstruction and in differentiation between homicide and suicide.     

Judicial-biotechnological system and the right to life: an approximation from the European and Spanish law]

This work consists in the systemisation of the complex and diversified of the group of normative regulations of life, of all life. This is based on the premises that it is a core value as a principle and a right and overcoming its static and predetermined conception, replacing it with a new, dynamic, individual and creative vision. Life, as a legal fact, is the basic idea in a wide legal regulation, that, notwithstanding the diversity and mobility of the norms relative to human, animal and vegetable life should be redirected at last instance towards a common and unitary legal status.     

Affecting trust: Terrorism,internet and offensive information warfare

The national security consequences of the potential use of the Internet by terrorist organizations have attracted the interest of many academics and government and intelligence officials. The goal of this article is to provide a new explanatory angle concerning the possible targets of terrorists’ offensive information warfare (OIW) operations. It argues that these organizations may prove more valuable and effective to undermine on‐line activities of leading electronic commerce sites than to target elements of the critical national information infrastructure. These offensive actions, in fact, would directly impact one of the explanatory elements for the Internet's success: users’ perception of its trustworthiness. Before tackling its arguments, the article provides a definition of offensive information warfare. Then, it investigates how terrorist organizations would formulate their operational style concerning offensive information warfare. The stage is then set to define the central argument of the article by drawing from studies carried out in the areas of information security, international management and electronic commerce. The article concludes with a set of policy recommendations to counter these potential threats and thus make the Internet a safer communication instrument for economic, commercial and social development.     

The case against lawyers’ contingent fees and the misapplication of principal-agent models

In this paper the case against the principal-agent modeling of most economic transactions is made about liberalizations of professional services that introduced in many European countries schemes of professionals’ remuneration contingent on outcomes—i.e. “contingent fees” for lawyers. If the relationship between the professional and clients is seen according to the principal-agent model, contingency fees can be economically justified. The case is quite different, however, if the situation is seen as one of authority under bounded rationality and unforeseen/asymmetrically gathered events. A game theoretical thought experiment aimed at checking the case for or against using agency models is carried out. It shows that (i) in the case of a self-interested professional, notwithstanding that overall utilitarian efficiency may be safeguarded, contingent fees leads to not respecting the fiduciary obligations (to detriment of Pareto optimality, impartial and loyal treatment of all clients, and the obligation to promote all the clients’ welfare). (ii) In the case of the professional’s willingness to comply with deontology standards—requiring impartial protection of all the clients’ rights and welfare, under a condition of minimal individual rationality—contingent fees lead nevertheless to making useless deontological motivations and to a loss of efficiency in utilitarian sense. A Pareto optimal, impartial, as well as efficient, arrangement aimed at maximizing the total volume of damage compensation is then considered. Nevertheless the main result is that, even if motivations to conform to such principles were available, under a contingent fee contract the professional could not carry out them because of the logic of the incentive contract. Thus, notwithstanding its widespread acceptance in the law and economics literature, agency theory seems not suitable in general for designing efficient and fair contracts and economic institutions.     

The Outbreak of Fentanyl‐Related Deaths in Cook County,Illinois, Between October 2015 and December 2017: A Retrospective Study and a Comparison with Previous Data

The National Institute on Drug Abuse has observed an increase in fentanyl deaths in the United States. One epidemic related to the abuse of fentanyl happened in Cook County in 2005–2007 (350 deaths). Another outbreak of fentanyl deaths occurred in 2015–2017 in the same area. The database of the Cook County Medical Examiner's Office was searched for cases of fentanyl deaths between 2015 and 2017: 1244 deaths were found. A comparison was performed with the previous data: an increase in the number of females was observed in 2015–2017. Also, in 2005–2007, the majority of deaths occurred among African American, while in 2015–2017, Caucasians were more involved. Within our population, some drug combinations were more common in specific demographic subgroups (male/females; Caucasian/African American; and certain age groups). The epidemiology and the most significant drug associations found at the toxicology are discussed, highlighting the usefulness of the knowledge about this outbreak for public health.
