A comparison of hair colour measurement by digital image analysis with reflective spectrophotometry

While reflective spectrophotometry is an established method for measuring macroscopic hair colour, it can be cumbersome to use on a large number of individuals and not all reflective spectrophotometry instruments are easily portable. This study investigates the use of digital photographs to measure hair colour and compares its use to reflective spectrophotometry. An understanding of the accuracy of colour determination by these methods is of relevance when undertaking specific investigations, such as those on the genetics of hair colour. Measurements of hair colour may also be of assistance in cases where a photograph is the only evidence of hair colour available (e.g. surveillance). Using the CIE L^*a^*b^* colour space, the hair colour of 134 individuals of European ancestry was measured by both reflective spectrophotometry and by digital image analysis (in V++). A moderate correlation was found along all three colour axes, with Pearson correlation coefficients of 0.625, 0.593 and 0.513 for L^*, a^* and b^* respectively (p-values = 0.000), with means being significantly overestimated by digital image analysis for all three colour components (by an average of 33.42, 3.38 and 8.00 for L^*, a^* and b^* respectively). When using digital image data to group individuals into clusters previously determined by reflective spectrophotometric analysis using a discriminant analysis, individuals were classified into the correct clusters 85.8% of the time when there were two clusters. The percentage of cases correctly classified decreases as the number of clusters increases. It is concluded that, although more convenient, hair colour measurement from digital images has limited use in situations requiring accurate and consistent measurements.     

Further data on the development of red blood cell antigens Lua,Lub, and Cob

One hundred and fifty-five cord cells were tested for the red blood cell antigens Lu^a, Lu^b and Co^b in order to collect data on the early postnatal expression of these markers. Additionally, dosage studies were carried out in 8–10-month-old heterozygous children. Antigens Lu^a and Lu^b revealed to be significantly less expressed in children of both ages compared with those of their mothers, whereas no such differences could be demonstrated in the expression of the antigen Co^b.

Why “Trauma-Related Dissociation” Is a Misnomer in Courts: a Critical Analysis of Brand et al. (2017a,b)

Forensic psychologists are sometimes faced with the task of educating triers of fact about the evidential weight of dissociative experiences reported by claimants in litigation procedures. In their two-part essay, Brand et al. (Psychological Injury and Law, 10, 283–297, 2017a; Psychological Injury and Law, 10, 298–312, 2017b) provide advice to experts who find themselves in such situation. We argue that the Brand et al. approach is problematic and might induce confirmation bias in experts. Their approach is not well connected to the extant literature on recovered memories, dissociative amnesia, memory distortions, and symptom validity testing. In some instances, Brand et al. (Psychological Injury and Law, 10, 283–297, 2017a; Psychological Injury and Law, 10, 298–312, 2017b) simplify the current body of knowledge about dissociation; in other instances, they ignore relevant empirical studies to an extent that is worrisome.     

Two Obscure Sanskrit Words Related to the C��rv��ka: pa?cagupta and ku??ak��?a

Two words, pañcagupta and ku??ak???a, are found in modern Sanskrit lexicons such as the ?abdakalpadruma, the V??caspatya, the Sanskrit-Wörterbuch, and A Sanskrit English Dictionary. They are said to signify the C??rv??ka philosophy and an expert in the C??rv??ka philosophy respectively. Both the words have been taken from some twelfth-century Sanskrit ko?as but no example of actual use is available. Nor do they occur in any earlier Sanskrit ko?a, such as the Amarako?a and the Hal??yudhako?a. The inference is that the words must have appeared in some late philosophical work that was critical of the materialist C??rv??ka system of philosophy and the ko?ak??ras found them in the same source.     

Telecommunications terminal equipment: EEC commission opens the market

The 12 Member States of the European Economic Community (EEC) are legally obliged by the Treaty of Rome, as amended by the Single European Act, to abolish all of the remaining physical, technical and fiscal barriers between them by 31 December 1992. The Single European Act, which sets the 1992 deadline, defines the envisaged internal market as “an area without internal frontiers”.The creation of a common European market for telecommunications services and equipment is both an essential prerequisite and an important part of the “internal market”.In its Green Paper on the Development of the Common Market for Telecommunications Services and Equipment — “the Green Paper”¹⁾) — and a follow-up Communication²⁾, the Commission of the European Communities (“the Commission”) has set forth its main policy proposals in the telecommunications field. Implementation of these policy proposals by means of Community law directives is progressing rapidly, in particular with respect to terminal equipment. On 16 May 1988, the Commission issued a“Commission Directive on Competition in the Markets in Telecommunications Terminal Equipment” — “Terminal Equipment Directive” —³⁾ based on its regulatory powers under Art. 90(3) of the Treaty of Rome (“EEC Treaty”).This article explores the regulatory scope of the Terminal Equipment Directive which has recently been challenged by the French government before the European Court of Justice.     

Is <Emphasis Type="Italic">Viveka</Emphasis> a Unique <Emphasis Type="Italic">Pramāṇa</Emphasis> in the <Emphasis Type="Italic">Vivekacūḍāmaṇi</Emphasis>?

This is an enquiry based on the Vivekacū?āma?i (VC), the primary focus of which is to present viveka (discrimination) along with its three catalysts, namely, ?ruti, tarka, and anubhava as the unique pramā?a of Ultimate Knowledge. This paper discusses the significance of the six popular pramā?as of Advaita Vedānta (AV) and reiterates that as far as AV is concerned epistemologically those pramā?as have merely a provisional value (vyāvahārika). In accordance with the purport of VC this paper argues that ?ruti and tarka, culminating in anubhava (trans-empirical insight sans experience) are blind in themselves and are enthusiastically carried forward by viveka (discrimination) for the attainment of the final realisation. This paper concludes that viveka, along with its three catalysts namely, ?ruti, tarka, and anubhava is the sole pramā?a of the trans-empirical experiential knowledge of Brahman.     

Paśyantī, Pratibhā, Sphoţa and Jāti: Ontology and Epistemology in the Vākyapadīya

Eli Franco has recently suggested to distinguish the two main periods in the history of Indian philosophy, i.e. the older ontological and the new epistemological. In the Vākyapadīya, however, ontology and epistemology are evidently intertwined and interrelated. In this paper ontological and epistemological features of the concepts of pa?yantī, pratibhā, spho?a and jāti are analyzed in order to demonstrate that all these concepts, while being ontologically different, are engaged in similar epistemological processes, i.e. the cognition of a verbal utterance. Thus the identification of spho?a and jāti as well as of pa?yantī and pratibhā met with in some passages of VP and the commentaries implies not the absolute identity of these concepts, but only their overlapping in the sphere of epistemology. Considering concepts of different origin in one epistemological perspective enables to escape controversies in interpretation and provides a kind of consistency in a bit but amorphous work of Bhart?hari.     

Criminal Punishment in Islamic Societies: Empirical Study of Attitudes to Criminal Sentencing in Iran

Public opinion on criminal sentencing and aims of punishment has been surveyed mostly in Western countries. In non-Western countries, especially Islamic societies, little has been published, at least in Western journals, on these issues. In fact, no published study examining public views toward criminal sentences and the aims of punishments in Islamic societies may be located in any major database of Western literature. As a result many questions like the relationship between perceived purpose of criminal punishment and its severity and the interactions between the belief in Islam and its Shari’a (Islamic culture) and punitive attitude to criminality have remained unasked. Therefore, the meaning and motive behind the death penalty and other severe forms of punishment in Islamic countries remains unknown to scholars, whether within or outside these countries. This paper introduces, first, Shari’a sentencing laws and practices in some Islamic societies and then, by drawing on a survey administered in Iran in 2008, tries to show and explain the variations in attitudes to Shari’a criminal laws and different forms of punishment, mostly based on Shari’a, across different genders and professions (judges, lawyers, students, Tulab and police).     

Trauma-Related Dissociation Is No Fantasy: Addressing the Errors of Omission and Commission in Merckelbach and Patihis (2018)

Dissociation is commonly a response to trauma that can be associated with significant impairment. In order to deal with dissociation in court from a comprehensive, scientifically informed, and valid perspective, Brand, Schielke, and Brams (Psychological Injury and Law, 10, 283-297, 2017a, b) provided a balanced view of dissociation, its characteristics, evidence base, and best assessment practices. Without an approach such as this, forensic experts risk having insufficient knowledge in its causation, phenomenology, and assessment and accordingly misunderstand trauma-related dissociation (TRD). Brand et al. (Psychological Injury and Law, 10, 283-297, 2017a, b) addressed this issue by providing an overview of TRD relevant to forensic contexts, acknowledging some of the erroneous and misinformed approaches to the topic. Merckelbach and Patihis (2018) offered a critique of Brand et al. (Psychological Injury and Law, 10, 283-297, 2017a, b) that illustrated this lack of knowledge and misunderstanding about TRD. Many of the statements made by these authors are conceptually inaccurate or scientifically misinformed. As we show, they were incorrect when they stated that research is lacking about the inter-rater reliability of dissociative disorder (DD) diagnoses. They were unaware of the error rates of tests and interviews among dissociative samples, which we present here. Merckelbach and Patihis challenged Brand et al., arguing their methods and literature review “lacked a connectivity to existing science” (p. 3), despite extensive citations of studies with DD patients. They argued that we failed to adequately consider malingering despite our discussions of empirically supported methods for assessing it. We show that Merckelbach and Patihis overlooked research that does not support their views. As we review their comments, we illustrate their pattern of misreading and misunderstanding our papers, as well as lapses in their reasoning. The current paper reinforces that in the forensic context, experts can acquire adequate understanding of TRD and its evidence base, and put forward arguments against any harsh critique of the area that is uninformed about, misunderstands, or includes omissions and errors in critical conceptualization, state-of-the-art assessment practices, and research methodology and results.     

Stealing more is better? An economic analysis of Islamic law of theft

This study is the first attempt (in the field of Law and Economics) to apply economic analysis to shari’a or Islamic criminal law, in particular, that aspect of the law pertaining to theft. Shari’a imposes two main punishments for theft; hadd, a fixed penalty of amputation of the offender’s right hand under certain conditions and ta’zir, a discretionary punishment, less severe than hadd. From the viewpoint of marginal deterrence and multiplier principles, lesser crimes with low social harm are punished more severely with hadd whereas crimes with high social harm are punished with ta’zir. Moreover, as the probability of detection and sanction is less in those crimes of high social harm, criminals would have more incentive to commit them. Consequently, if Islamic criminal law is to be applied in its current form, crimes of high social cost are likely to become more frequent.     

Identification of a forensic case using microscopy and forensically informative nucleotide sequencing (FINS): A case study of small Indian civet (Viverricula indica)

The exhibits obtained in wildlife offence cases quite often present a challenging situation for the forensic expert. The selection of proper approach for analysis is vital for a successful analysis. A generalised forensic analysis approach should proceed from the use of non-destructive techniques (morphological and microscopic examination) to partially destructive and finally destructive techniques (DNA analysis). The findings of non-destructive techniques may sometime be inconclusive but they definitely help in steering further forensic analysis in a proper direction. We describe a recent case where a very small dried skin piece (< 0.05 mg) with just one small trimmed guard hair (0.4 cm) on it was received for species identification. The single guard hair was examined microscopically to get an indication of the type of species. We also describe the extraction procedure with a lower amount of sample, using an automated extraction method (Qiagen Biorobot EZ1^®) and PCR amplification of three mitochondrial genes (16s rRNA, 12s rRNA and cytochrome b) for species identification. Microscopic examination of the single hair indicated a viverrid species but the initial DNA analysis with 16s rRNA (through NCBI BLAST) showed the highest homology (93%) with a hyaenid species (Hyaena hyaena). However, further DNA analysis based on 12s rRNA and cytochrome b gene proved that the species was indeed a viverrid i.e. Viverricula indica (small Indian civet). The highest homology shown with a Hyaenid species by the 16s rRNA sequence from the case sample was due to lack of a 16s rRNA sequence for Viverricula indica in the NCBI data base. The case highlights the importance of morphological and microscopic examinations in wildlife offence cases. With respect to DNA extraction technology we found that automatic extraction method of Biorobot EZ1^® (Qiagen) is quite useful with less amount of sample (much below recommended amount).     

S—s—U— phenotype in the coloured population of Cape Town: Problems encountered in paternity tests

Two Cape Coloured persons of mixed White, Khoikhoi, Malay, Black parentage in Cape Town whose red cells were found to be S—s—U— establish that the rare S^u allele is present in this population group. The most likely source of the S^u allele in them is the non-indigenous Black slaves who were brought to the Cape in the early years of White settlement there. In two paternity suits involving Cape Coloured persons, maternal and paternal exclusions were present unless the inheritance of an MS^u or an NS^u chromosome was postulated, and MS, NS and Ns chromosomes were seen to accompany He+ alleles in them.     

Students’ foundational understanding of chemical reaction in the forensic science bachelor’s degree program at the National Autonomous University of Mexico

ObjectiveTo compare the understanding of the concept of chemical reaction—as operationalized by Bloom’s taxonomy of cognitive levels—of students in forensic science bachelor’s degree with that achieved by students majoring in chemistry, as a prerequisite for future professional collaboration and communication.Materials and methodsUsing previously validated and published tests developed to assess students’ knowledge, comprehension, and application of the concept of chemical reaction, we explored how conceptual understanding developed in students enrolled in (a) a forensic science degree program in a Mexican public university and in (b) chemistry undergraduate programs offered by the same university, and whether both groups achieved comparable attainment levels.Findings and implicationsDespite receiving considerably less chemical instruction, forensic science students achieved comparable levels of conceptual understanding of chemical reaction to those exhibited by chemistry students. This finding is encouraging because it might mean that future forensic scientists could graduate with a solid foundation of chemical knowledge. More research, particularly on the learning of other key concepts, will be needed to verify these initial findings.     

A fatal poisoning involving Bromo-Dragonfly

This paper reports a fatal overdose case involving the potent hallucinogenic drug Bromo-Dragonfly (1-(8-bromobenzo[1,2-b; 4,5-b′]difuran-4-yl)-2-aminopropane). In the present case, an 18-year-old woman was found dead after ingestion of a hallucinogenic liquid. A medico-legal autopsy was performed on the deceased, during which liver, blood, urine and vitreous humour were submitted for toxicological examination. Bromo-Dragonfly was identified in the liver blood using UPLC–TOFMS, and was subsequently quantified in femoral blood (0.0047 mg/kg), urine (0.033 mg/kg) and vitreous humour (0.0005 mg/kg) using LC–MS/MS. Calibration standards were prepared from Bromo-Dragonfly isolated from a bottle found next to the deceased. The structure and purity of the isolated compound were unambiguously determined from analysis of UPLC–TOFMS, GC–MS, HPLC–DAD, ¹H and ¹³C NMR data and by comparison to literature data.The autopsy findings were non-specific for acute poisoning. However, based on the toxicological findings, the cause of death was determined to be a fatal overdose of Bromo-Dragonfly, as no ethanol and no therapeutics or other drugs of abuse besides Bromo-Dragonfly were detected in the liver, blood or urine samples from the deceased. To our knowledge, this is the first report of quantification of Bromo-Dragonfly in a biological specimen from a deceased person. This case caused the drug to be classified as an illegal drug in Denmark on 5th December 2007.     

Subjective Strains, Conditioning Factors, and Juvenile Delinquency: General Strain Theory in Taiwan

Agnew’s [Agnew, R. Journal of Research in Crime and Delinquency, 38(4), 319–361, 2001, 2006a, 2006b] general strain theory (GST) argues that subjective strain and objective strain should be distinguished from each other, and that subjective strain should be related more strongly to delinquency. In addition, GST suggests that the strain–delinquency relationship is conditioned by certain conditioning factors, and that research should treat these conditioning factors as a whole, i.e., the individual’s “overall” standing regarding these conditional factors. The present study uses a random sample of Taiwanese adolescents (13–17 years old) to study these two issues. The results suggest that strain as measured in this study is related positively to delinquency; however, subjective strain does not differ from objective strain in predicting delinquency. Additionally, the “overall standing” conditioning factors interact differently with subjective strain and objective strain but in the expected direction.     

Once Again on the *Hetucakraḍamaru: Rotating the Wheels

The little versified treatise on the elements of Buddhist logic, often referred to as the Hetucakra?amaru, is usually attributed to Dignāga. It is only available in a Tibetan translation and quotations from a few of its verses are extant in Sanskrit sources. On the basis of a novel interpretation that is based on a critical edition of the text, we argue that there is a good reason why its title was Hetucakra?amaru - a ?amaru is a two-headed drum. The “heads” of the drum are circular and they refer to the sapak?a and vipak?a conditions of the logical reason (hetu). These “wheels” can be turned clock-wise and counter clock-wise. The nine positions that are located on the wheels do remind one of a dharmacakra, which has a center and eight positions that are placed around it as if it were a compass. We illustrate our interpretation of the text by means of various diagrams.     

Chapter 14: Encephalitis

Encephalitis is infectious inflammation of the brain. The following types may be provisionally distinguished: (a) primary encephalitis with direct infection of the brain, and (b) secondary encephalitis, caused by various general infections.
