We report a case where an alleged father (AF) attempted to substitute someone else's saliva sample for his reference sample in a paternity analysis. Buccal cells were collected from the AF and the child, and DNA analysis was performed using an autosomal STR loci (Identifiler). The profile from the AF showed extra peaks in some loci, as well as a much higher "X" allele peak relative to the "Y" allele peak at the amelogenin locus. After conducting reanalysis by another technician with another set of positive and negative controls, it was concluded that the only source of the mixed profile was by intentional introduction by the AF, at the time of sampling, of some foreign human biological material, most likely saliva from a woman. Owing to the inconclusive results, when the AF was called back to the lab and the peculiar results were explained to him, he admitted that he had introduced into his mouth saliva from another person in an attempt to be excluded as the father of the child. Although tampering with DNA reference samples is not common, some individuals may attempt to contaminate or otherwise adulterate specimens before DNA tests. Personnel responsible for sampling should be aware of this possibility and should try to establish procedures to avoid the problem.  相似文献

§ 51 MedienG ist im Verh?ltnis zu § 34 Abs 5 MedienG als lex posterior anzusehen, die der letztgenannten Bestimmung (teilweise, soweit § 51 MedienG auf eine Urteilsver?ffentlichung in einem ausl?ndischen Medium anzuwenden ist) derogiert hat. Ver?ffentlichungen haben grunds?tzlich im (auch ausl?ndischen) Medium selbst (durchsetzbar nach § 20 MedienG) – und nicht in einem Ersatzmedium – zu erfolgen. Die internationale Zust?ndigkeit des inl?ndischen Gerichts für die Anordnung der Urteilsver?ffentlichung als zivilrechtlichen Anspruch iSd EuGVVO auch auf einer Website bestimmt sich nach Art 5 Nr 3 EuGVVO, wonach Ansprüche aus einer unerlaubten Handlung (Deliktsklage) auch an jenem Ort geltend gemacht werden k?nnen, an dem das sch?digende Ereignis eingetreten ist. Auch die vom EuGH für ehrenrührige ?u?erungen in Medien entwickelte Sonderregel, nach der der Gesch?digte nicht in allen Staaten, in denen die ?u?erung verbreitet wurde, den gesamten Schaden einklagen kann, sondern jeweils nur jenen Teil, der sich in dem Staat konkret verwirklicht hat, steht dem nicht entgegen.  相似文献

Although determination of diagnosis of cognitive impairments constitutes one of the core objectives of forensic neuropsychological assessment, the diagnostic criteria for cognitive disorders provided by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR, American Psychiatric Association 2000) have been of low internal and external validity and limited utility. This paper reviews the evolution of diagnosis of cognitive disorders from current DSM-IV-TR to the proposed DSM-V (American Psychiatric Association 2010). The conceptual framework is tracked, along with the body of literature associated with the DSM-V proposal on Minor and Major Neurocognitive Disorders. The quality of evidence for internal and external validity is reviewed, as well as the fairness and utility of newly proposed diagnoses from both clinical and forensic perspectives. Significant conceptual, evidentiary, psychometric, assessment, and practical questions are raised related to the new classification, and recommendations are offered for improvement to the proposal of the DSM-V Work Group on Neurocognitive Disorders.  相似文献

Despite the initially cordial relationship between the United States and Russia following the September 11, 2001 attacks, the Iraq War became a turning point in what evolved into the worst relationship between Moscow and Washington since the Cold War. From that point onwards, Russia persistently has exhibited aggressive behavior toward the United States, resulting in numerous crises. This article argues that this Russian assertiveness is deliberate, arising from a mixture of domestic and international factors. In light of recent developments in U.S.-Russian relations, especially the decision of American President Barack Obama to abandon the Bush Administration's scheme to deploy national missile defense (NMD) system in Eastern Europe, it is important to understand that Russia's grand strategy is aimed at promoting multipolarity and that Moscow is willing to apply limited military force to achieve its goals. The Obama Administration should engage Russia, but be prepared to confront it if necessary.  相似文献

Objective: To detect the changes of (interleukin, IL)-1α, IL-1βand IL-13 mRNA in lung tissue and serum of drown rats, and to explore the potential value for the diagnosis of drowning in forensic practice. Methods: Eighteen SD rats were randomly divided into drowning group, blank control group and myocardial infarction group (as control group). The serum of right ventricular, the inferior lobe of right lung and the myocardium were taken from the rats in different groups. The expressions of IL- 1α, IL-1βand IL-13 mRNA in the lung tissue and the serum of right ventricular were detected by TaqMan probe method. Results: The expression differences of IL-1α, IL-1βand IL-13 mRNA in lung tissue between drowning group and blank control group, myocardial infarction group were not statistically significant (P>0.05). The expression of IL-1βand IL-13 mRNA in serum of right ventricular increased (P<0.05). The expression differences of IL-1α, IL-1βand IL-13 mRNA in serum between blank control group and myocardial infarction group were not statistically significant (P>0.05). Conclusion: The changes of cytokines IL-1βand IL-13 mRNA in the serum of right ventricular of drown rats are statistical significance, which are highly correlated with drowning. © 2018 by the Editorial Department of Journal of Forensic Medicine.  相似文献

As research on the cognitive impact of medical conditions and mental health disorders advances, it is imperative for forensic neuropsychologists to stay abreast of rapidly accumulating new empirical evidence from neuroscience and neuropsychology to disentangle multiple determinants of cognitive impairment. Although medicolegal neuropsychological assessments traditionally focused on traumatic brain injury (TBI) sequelae, it is equally important to consider the potential impact of any other acquired, or secondarily induced brain impairments, regardless of their source. Such injuries or conditions are at times assumed to cause a lesser cognitive impact than TBIs; however, their effects depend entirely on the factor in question. Injuries and illnesses implicated in civil litigation—and eventually affecting competency—can indeed involve TBI, but also anoxic/hypoxic injuries, pain, depression, posttraumatic stress disorder (PTSD), sensory deficits (e.g., tinnitus), and fatigue, and all, in turn, can affect an individual’s cognitive function and quality of life. Impairments caused by these conditions can be disabling and resistant to treatment, particularly, when the treatment is based on incorrect diagnostic, prognostic, and causality assumptions.  相似文献

Pulmonary injuries, respiratory distress, blood loss-related cerebral blood perfusion, and major surgeries are common features of medical histories in forensic neuropsychological assessments. Unless the explicit reason for referral is determination of the cognitive impact of one of these adverse medical conditions, their contribution to neuropsychological causality determination can be overlooked, minimized, or misattributed to other causes. Given the underlying common denominator among these conditions, that is, sub-optimal oxygen delivery to the brain, transient or long-term debilitating injuries causing neuropsychological change of various degrees can result. A thorough understanding of the impact of these medical events is paramount in forensic neuropsychological assessment for diagnosis, causality, and functional impact determination, prognosis, rehabilitation, and recommendations. In this paper, we critically review the available empirical evidence regarding anoxia and hypoxia arising from pulmonary injuries and respiratory distress, cerebral blood hypoperfusion, and major surgeries, together with evidence of their impact on cognitive functioning. Medical and psychological electronic search engines [PubMed, PsycINFO, and Google Scholar (up to January 2018)] have been screened for neuroscience-related and neuropsychological literature pertaining to pulmonary injuries and respiratory distress, cerebral blood perfusion, and major surgeries, and subsequently optimized for the issue under review.  相似文献

This article analyzes the development of foreign investment regulations and their impact on FDI flows in Mexico. The study covers the evolution of sectoral and aggregate investment patterns from the independence period to the 1994 Peso crisis and its aftermath. The pattern followed by FDI in Mexico has paralleled the transformation of the Mexican economy itself, focusing initially on the extractive and agricultural sectors, then on manufacturing activities, and recently on the services sector. Mexico has continuously reformed and modernized its regulatory system in order to adapt to internal political changes and changes in the world economic environment. Recent economic reforms and liberalization of FDI regulations have had a major positive impact on capital inflows, but more needs to be done, especially in the area of financial services in order to achieve a higher level of economic efficiency and to prevent financial breakdowns like the one experienced in 1994.  相似文献
