Stochastic modeling of a serial killer  [PDF]
M. V. Simkin,V. P. Roychowdhury
Quantitative Biology , 2012,
Abstract: We analyze the time pattern of the activity of a serial killer, who during twelve years had murdered 53 people. The plot of the cumulative number of murders as a function of time is of "Devil's staircase" type. The distribution of the intervals between murders (step length) follows a power law with the exponent of 1.4. We propose a model according to which the serial killer commits murders when neuronal excitation in his brain exceeds certain threshold. We model this neural activity as a branching process, which in turn is approximated by a random walk. As the distribution of the random walk return times is a power law with the exponent 1.5, the distribution of the inter-murder intervals is thus explained. We illustrate analytical results by numerical simulation. Time pattern activity data from two other serial killers further substantiate our analysis.

El Agora USB , 2009,
Abstract: The goal of this research is to show an analysis of the psychological and forensic assessment carried out to a serial killer in the city of Medellin. In it, some historical aspects of the serial killer are made, including his characteristics and different types; as well as a description of the crimes, the killer's modus operandi and his assessment and personality profile. All of this is framed in the respect and the ethics, since this research does not attempt to judge the murder, but to analyze the phenomenon of his psychotic personality taking into account the diverse factors, whichare interrelated.
Serial Murder of Four Victims, of Both Genders and Different Ethnicities, by an Ordained Baptist Minister
James A. Reavis
Case Reports in Psychiatry , 2011, DOI: 10.1155/2011/163403
Abstract: A case of a 61-year-old African-American male who sexually assaulted and murdered four individuals, of different ethnicities and both genders, is reported. The subject additionally engaged in sexual activity with each victim postmortem. Each murder is reviewed in detail, and the subjective state of the offender during the murders is commented upon. Psychological test data are reviewed. The subject met criteria for several Axis I disorders, including Bipolar I Disorder, Pedophilia, and Sexual Sadism, and met criteria for Axis II diagnoses of Narcissistic and Antisocial Personality disorder. He was additionally classified as a Psychopath, which, in combination with his Sexual Sadism, general psychiatric state, and exquisite sensitivity to humiliation, led to his decision to murder.
Serial Killing of Tumor Cells by Human Natural Killer Cells – Enhancement by Therapeutic Antibodies  [PDF]
Rauf Bhat, Carsten Watzl
PLOS ONE , 2007, DOI: 10.1371/journal.pone.0000326
Abstract: Background Natural killer cells are an important component of the innate immune system. Anti-cancer therapies utilizing monoclonal antibodies also rely on the cytotoxicity of NK cells for their effectiveness. Here, we study the dynamics of NK cell cytotoxicity. Methodology/Principal Findings We observe that IL-2 activated human NK cells can serially hit multiple targets. Using functional assays, we demonstrate that on an average, a single IL-2 activated NK cell can kill four target cells. Data using live video microscopy suggest that an individual NK cell can make serial contacts with multiple targets and majority of contacts lead to lysis of target cells. Serial killing is associated with a loss of Perforin and Granzyme B content. A large majority of NK cells survive serial killing, and IL-2 can replenish their granular stock and restore the diminished cytotoxicity of ‘exhausted’ NK cells. IL-2 and IL-15 are equally effective in enhancing the killing frequency of resting NK cells. Significantly, Rituximab, a therapeutic monoclonal antibody increases the killing frequency of both resting and IL-2 activated NK cells. Conclusion/Significance Our data suggest that NK cell-based therapies for overcoming tumors rely on their serial killing ability. Therefore, strategies augmenting the killing ability of NK cells can boost the immune system and enhance the effectiveness of monoclonal antibody-based therapies.
Delirio omicidiario condiviso nelle coppie di serial killer / Délire homicidaire partagé par les couples de tueurs en série / Shared psychotic disorder in serial killers acting in pair  [PDF]

Rivista di Criminologia, Vittimologia e Sicurezza , 2012,
Abstract: Les tueurs en série qui agissent en couple sont très rares d’un point de vue statistique. Le plus souvent, entre les deux membres du couple, un délire commun appara t progressivement, conduisant ces sujets à réitérer ensemble les passages à l’acte homicidaire.Ce cadre clinique prévoit qu’un individu, défini comme dominant et nommé Inducteur ou Cas primaire , influence un individu plus faible, nommé Induit , en lui imposant son système délirant. Le plus souvent, le membre du couple le plus faible ne provient pas d’une sous-culture criminelle et ne souffre d’aucun trouble psychiatrique qui justifierait son adhésion aux actions de l’individu dominant. Le syndrome a été décrit pour la première fois par Lasègue et Falret à la fin du XIXème siècle et nommé folie à deux ; le DSM-IV TR parle de trouble psychotique partagé .Les couples de tueurs en série les plus représentés d’un point de vue statistique sont composées de deux hommes, puis par un homme et une femme et, enfin, par deux femmes.Le lien entre les deux membres de ces couples peut être de type amical, sentimental ou de parenté.Bien que le Cas primaire soit dominant dans le couple, il ne faut pas négliger la contribution de l’individu faible au délire homicidaire partagé : en effet, sur la base de la logique particulière d’une relation complémentaire pathologique, les deux acteurs jouent un r le majeur et fonctionnel à la continuité de la relation. Même l’individu apparemment le plus passif et soumis joue un r le actif dans la formation du délire homicidaire partagé.Serial killers acting in pair represent an event which is statistically very rare. A sort of common delirium gradually structured between the two members of the pair, brings them to reiterate their homicidal actions.This clinical situation provides that a person described as dominant and called “inducer” or “primary” or “principal” imposes on another person knows as “the secondary”, “acceptor” or “associate” who gets to share the delirium of the “inducer”.The secondary person does not often come from a criminal subculture and does not have any psychiatric pathology which can justify his/her compliance to the actions of the “inducer”.This syndrome described for the first time at the end of the 19th century by Lasègue and Falret was called “Folie à deux”. In the DSM-IV-TR is known as Shared Psychotic Disorder.These pairs of serial killers statistically more representative are those made up of two men, or a man and a woman or two women. Between the two members there may be a friendly, loving or relationship tie.Even if the
Abortion: Is it Suicide in the Guise of Murder?  [PDF]
Didem Gediz Gelegen
Fe Dergi : Feminist Ele?tiri , 2011,
Abstract: The concept of “rights” is central to most of the arguments on abortion in medical ethics. The common approach is the comparison of embryo’s “right to life” and woman’s “right to decide about her body”; and the issue is handled as a “conflict of interests”. This approach can not embrace the issue. Perhaps, the most important point is neglected.In this essay, I will try to develop my argument from “women’s point of view.” I will point out that, in the cases of abortion embryo and the woman are not sides in conflict. Since women’s sense of self is continuous with the others, women are, also, violated in abortion. Abortion is defined as “murder” in the arguments of its opponents. I will offer to define it, rather, as a kind of “suicide” from women’s point of view.
The Catholic Imagination
Carlos Ojeda Aureus
Humanities Diliman , 2000,
Abstract: First of all, what this paper is not: This is not a paper that will analyze the works of Catholic writers. This journal is not the proper venue for that. Too, this is not a study of the doctrinal and propositional Church we call Catholic. Again, this journal is not the venue for that. Instead, I want to present a conceptual framework, an aesthetic theory, if you will, of a particular imagination I’d like to describe as Catholic. After this little “housecleaning,” I’d like to begin by diagnosing the illness of our secular society. (Later, I shall introduce an approach that I discovered—or rather re-discovered—which might allow us to heal the illness.) I use the metaphor of illness because I believe our secular society is sick. We need no special talent to be convinced of this condition. The symptoms of this sickness can be found everywhere. Every time you turn on the radio, or browse the newspapers, or flick on the TV set, you find yourself assaulted by a daily goulash of incestuous rapes, murders, drug-related crimes, fraternity-related violence, bombings, kidnappings, graft and corruption, and so on and so forth, the catalogue of abuses is legion. Every one of us is convinced that the planet is gravely ill and needs healing—on a grand scale. Few of us know exactly where the problem lies.

Another Look at a Bahamian Mystery: The Murder of Sir Harry Oakes  [cached]
LeGrand, Cathy
International Journal of Bahamian Studies , 2010,
Abstract: Stop me if you've heard this one:The richest man in the Bahamas, no, the richest man in the British empire, is murdered in his bed. He has suffered a fatal head wound caused by a boat's winch lever. Or by bullets from a small-caliber gun. No, by a conch shell. Or by some blunt object close at hand, still unidentified.The rich man's body is set afire in order to burn down his house and conceal the details of the crime. Or as a diversionary tactic, to confuse the authorities. No, in a voodoo ritual.The killer is his son-in-law. Or his houseguest. Or a mafia hitman.The reason for the murder: to eliminate a powerful opponent of casino gambling. Or to prevent this rich man from leaving the Bahamas with his businesses and wealth. Or to avenge the rich man's resentment of his daughter's choice of husband. Or to steal the enormous horde of gold reported to be hidden in his house.The richest man in the Bahamas (if not the whole Empire) was Sir Harry Oakes, who earned his fortune from gold prospecting and spent the rest of his life avoiding the tax man. He was found murdered in the morning of 8 July 1943, having been killed sometime after midnight during a summer thunderstorm. His body, bearing four lethal head wounds and burns from the fire, was discovered the next morning by his close friend and houseguest, Harold Christie, an influential Bahamian estate agent.Add to this cast of characters a smooth-operating Mauritian (Alfred de Marigny) married to Oakes' young daughter; a former King of England (the Duke of Windsor), now forced to serve this tiny colonial outpost; and the Duke's scandalous wife (the Duchess of Windsor), for whom he renounced his crown.Also, factor in the war raging around the globe. France had recently fallen to the Nazis; German U-boats patrolled the Atlantic; and the shortages and other exigencies of wartime were the rule. The trial of Alfred deMarigny, Oakes' son-in-law, made international news and his eventual acquittal left the case unsolved -- it remains unsolved today. Let us not forget the recurring legend of all the “unexplained killings of people directly, or indirectly, involved” with the Harry Oakes murder. (Marquis 6) This may sound too good to be true. It may sound like the plot to a best-selling pot-boiler. And it all serves to explain the continuing interest in the murder of Sir Harry Oakes, often referred to, hyperbolically (and hyperbole is in no short supply in the coverage of the murder), as "the crime of the century."

To concept of imagination of islamic philosophy
Zary N.
Sociosfera , 2010,
Abstract: The imagination as representation about nonexistent, is convenient way of designing of the validity as in the form of concepts and conclusions, and artistic images. The given layer of human consciousness based on guesses, assumptions, imaginations, in certain degree unconscious, is a subject of steadfast attention of researchers. By means of imagination it is possible to think of that is unimaginable by means of usual thinking. The reason leans against practice; the imagination can go further and create the inconceivable.
