Based on a broad literature about service operations management, service value and public service value, this thesis has taken for granted that to know the value which a service must deliver to its main stakeholders is prior to organize it. According to literature, value might be created since designing public institutions until managing them. To integrate the different perspectives, it was used an approach that evaluates service value creation from the consequences on to its customers and the necessary resources to deliver them. These consequences were analyzed under four dimensions: utility, justice, solidarity, and aesthetic. Recourses analyzed were competences and technology. Thus, this thesis s purpose was to define the value of Forensic Science Service (FSS) to its main stakeholders. The specific objectives, which generated propositions, were: to find out the role played by FSS in its interorganizational network, to find out the main FSS characteristics, to identify critical factors for value delivery, and to propose some guides to design FSS. To achieve these objectives, a five-year qualitative, longitudinal and exploratory case study was carried out in a FSS federation unity. Subsidiary information was collected in six other FSS. Data also were collected from FSS stakeholders, using multiple methods. Results were analyzed and criticized based on theory. The findings showed that FSS takes part in a Public Safety and Criminal Justice interorganizational network and provide it with a service: the production of forensic evidence. FSS operations present exams variety, process variability, layout by fixed position in front office, and stakeholders diversity. FSS association with science highlights its intangibility. FSS utility dimension is to link the suspect to crime scene (or innocent someone wrongly accused) using science and technology, that is, it helps to build a narrative, in which defendants behaviors are trialed according to the law. There are obstacles on delivering this value dimension, like miscoordination among network members on crime scene preservation, for instance. The justice dimension assumes that every citizen must have access to FSS, independent of any pre-existing condition. Although, FSS hasn t been universalized yet. The solidarity dimension has a deeply conexion with Human Rights, both in avoiding constraining suspects during criminal investigations, and contributing to fair trials, in the sense that either prosecution or defense have access to the service in equal terms. However, FSS subordination to the Police jeopardizes its impartiality. The aesthetic dimension consists on helping Police solve crimes without constraining suspects. Besides the technical competence, FSS personnel need a communicational competence to a full client s knowledge. The technological resources are part of production process and critical for value delivery. Concluding, FSS should be redesigned as an independent agency in order to increase Criminal Justice impartiality. Finally, the study encourages reflections about the difficulties of applying service operations management concepts to a public organization that is changing, and it´s characterized by the diversity of stakeholders and by its fluid and poorly defined, although important value. / A criação de valor para a sociedade e ganhos em eficiência, eficácia e efetividade são motivos de preocupação no setor público. Baseada em uma ampla literatura sobre gestão de operações de serviços e valor de serviço, incluindo serviços públicos, esta tese partiu do pressuposto de que saber o valor de um serviço para os seus principais stakeholders é prioritário para organizá-lo. Segundo a literatura, valor pode ser criado desde o desenho até a gestão de instituições. Para integrar as perspectivas, abordou-se a criação de valor a partir das consequências para os destinatários do serviço e dos recursos necessários para produzi-las. Estas consequências são analisadas sob quatro dimensões: utilidade, justiça, solidariedade e estética. E os recursos analisados foram competências e tecnologias. Assim, o propósito dessa tese foi definir o valor do serviço de perícia criminal para os seus principais stakeholders. Os objetivos específicos, que geraram proposições, foram: investigar o papel desempenhado pelo serviço em sua rede interorganizacional; abordar suas principais características; identificar fatores críticos para a entrega de valor e propor algumas diretrizes a fim de projetar o serviço. Com o propósito de atingir esses objetivos, um estudo de caso qualitativo, exploratório e longitudinal de cinco anos foi realizado em um órgão pericial. Subsidiariamente, coletaram-se informações em seis outros órgãos periciais. Foram coletados, também, dados de stakeholders do serviço, utilizando-se múltiplos métodos. Os resultados foram analisados e discutidos com base na teoria. Esses resultados mostraram que a perícia criminal integra uma rede interorganizacional de segurança pública e justiça criminal e produz um serviço: a prova pericial. O serviço apresenta variedade de exames, variabilidade de processos, arranjo posicional na linha de frente e diversidade de stakeholders. A associação entre o serviço e a ciência realça sua intangibilidade. A dimensão de utilidade do serviço é vincular o suspeito ao local do crime (ou inocentar alguém erroneamente acusado), utilizando a ciência e a tecnologia, ou seja, auxiliar a construção de uma narrativa, para que as condutas dos réus sejam julgadas de acordo com a lei. Há obstáculos na entrega desta dimensão, como, por exemplo, as dificuldades de coordenação entre os atores da rede na preservação do local de crime. A dimensão de justiça presume que todo cidadão tenha acesso ao serviço, independente de qualquer condição pré-existente. Entretanto, este acesso ainda não foi universalizado. A dimensão de solidariedade tem relação profunda com os Direitos Humanos, tanto para evitar que suspeitos sofram constrangimentos durante investigações criminais, quanto contribuindo para julgamentos justos, de forma que acusação e defesa tenham igual acesso ao serviço. Porém, a subordinação do serviço a Polícia compromete sua imparcialidade. A dimensão estética consiste em auxiliar a Polícia a desvendar crimes sem constranger suspeitos. Além da competência técnica, os peritos precisam ter competências comunicativas, para conhecerem os clientes. Os recursos tecnológicos são parte do processo de produção do serviço e críticos para a entrega de valor. Concluindo, o serviço de perícia criminal deveria ser redesenhado institucionalmente como um órgão independente, para incrementar a imparcialidade da Justiça. Finalmente, o estudo encoraja reflexões sobre as dificuldades em aplicar os conceitos de gestão de operações a um serviço público em mudança, que é caracterizado pela diversidade de stakeholders e por seu valor fluido e pouco definido, porém relevante.

Using the Rondônia's Forensic Experts Forum, through the Internet, it was released selected questions about the concepts of once discussed themes and also about the perspectives of changes in the form of criminal forensics in the Rondônia state provinces. In addition, it has been accomplished data analysis of population, geographic locations, police reports and number of criminal forensics officers; bibliographic reviews and documental searches. The poll applied with criminal forensics professionals reveals unfamiliarity related to the difference between the key concepts shown in this study, although they reconizes the need of a deconcentration in the Scientific and Technical Division of this Police Department. This deconcentration purposes mostly the recognition of the regional sectors and the improvement of the work provided to society. The data related to the field of each sector inside Institute of Criminalistics, including current and dismantled ones, were analyzed. After that, the need of deconcentration of the criminal forensics in the inner state of Rondônia became even clearer, which proves the urgent need about origination of management sectors attuned to the central organ, yet only if performed as public politics. / Este estudo apresenta como questão central: Por que desconcentrar o Departamento de Polícia Técnica e Científica com a criação e implantação de coordenadorias nas sub-regiões da Secretaria de Segurança Pública, Defesa e Cidadania do Estado de Rondônia? Para responder tal questão que norteia o presente estudo volta-se o enfoque para a gestão dos serviços praticados pelos órgãos de perícia técnica nas diversas regiões do Estado visando o princípio da eficiência e da produtividade, bem como do aspecto social dos órgãos de segurança pública, pois, em última análise, são estes os que deveriam agir em conjunto com a sociedade visando a garantia da aplicação da lei e da justiça a todos, com o objetivo de contribuir na gestão dos órgãos regionais, além de atender ao controle social pelo cidadão, com a criação de coordenadorias regionais naquela instituição. Como instrumento para coleta de dados optou-se pelo questionário com perguntas selecionadas sobre os conceitos dos temas abordados, e sobre as perspectivas de mudanças de formatação diferenciada da perícia no interior do estado aplicado através do fórum dos Peritos Criminais do Estado de Rondônia, via internet. Também foram realizadas pesquisas bibliográficas, documentais e a análise de dados populacionais, geográficos, de ocorrências policiais e de número de peritos. Os dados mostram que entre os profissionais da área existe um desconhecimento da distinção entre os conceitos de desconcentração e de descentralização. Apesar desse fato, as respostas apontam para a unanimidade com relação à necessidade de haver uma desconcentração do setor, que visa o reconhecimento das unidades regionais e a melhoria do trabalho produzido para a sociedade. Ao confrontar os dados referentes à área de atuação de cada uma das sub-regiões do Instituto de Criminalística, dentre as quais as unidades existentes e as desarticuladas (com área geográfica de atuação, população atingida e número de ocorrências realizadas por período de tempo escolhido), com os dados obtidos simultaneamente na sede fixada à capital do estado, ficou ainda mais clara a necessidade de desconcentração da perícia criminal no interior do estado, constatando-se a urgente e necessária criação de polos gestores em sintonia com o órgão central, desde que tal seja realizado como política pública.

Background: There is a widespread and increasing use of psychoactive prescription drugs, such as opioid analgesics, anxiolytics, hypnotics and anti-epileptics, but their use is associated with a risk of drug use disorder, misuse and abuse. Today, these are globally recognized and emerging public health concerns. Aim: The aim of this thesis is to estimate the prevalence of psychoactive prescription drug (PPD) use disorders, misuse and abuse, and to investigate the association with some potential risk factors. Methods: A study using register data from forensic cause of death investigations investigated and described cases of fatal unintentional intoxication with tramadol (Study I). Based on register data on spontaneously reported adverse drug reactions (ADRs) reported cases of tramadol dependence were investigated and summarised (Study II). In a study in suspected drug-impaired drivers with a toxicology analysis confirming the intake of one out of five pre-specified PPDs, the prevalence of non-prescribed use was assessed and associated factors were investigated (Study III). From a cohort of patients initiating prescribed treatment with pregabalin, using data on prescription fills, a study investigated longitudinal utilisation patterns during five years with regards to use of the drug above the maximum approved daily dose (MAD), and factors associated with the utilisation patterns (Study IV). Results: In the first study, 17 cases of unintentional intoxications were identified, of which more concerned men, the median age was 44 years and the majority used multiple psychoactive substances (alcohol, illicit drugs and prescription drugs). The second study identified 104 spontaneously reported cases of tramadol dependence, in which more concerned women, the median age was 45 years, and a third reported a history of substance abuse and 40% of past psychoactive medication use. In the third study, more than half of the individuals suspected of drug-impaired driving used the drug without a recent prescription. Non prescribed use was most frequent in users of benzodiazepines and tramadol, and was more likely in younger individuals and in multiple-substance users. In the last paper five longitudinal utilisation patterns were found in pregabalin users, with two patterns associated with a particularly high risk of doses above the maximum approved dosing recommendation. This pattern of use was associated with male sex, younger age, non-urban residency and a recent prescribed treatment with an antiepileptic or opioid analgesic drug. Conclusions: This thesis shows that psychoactive prescription drug use disorders, misuse and abuse occur and may have serious and even fatal consequences. The prevalence varies between different drugs and populations. Abuse and misuse seem to be more common in young people. Fatal intoxications and misuse of prescribed drugs may be more common in men, while drug use disorders following prescribed treatment may be more common in women and non-prescribed use equally distributed between women and men. Individuals with a history of mental illness, substance use disorder or abuse, or of past use of psychoactive medications are likely important risk groups. In summary, the findings suggest a potential for improvements in the utilisation of psychoactive prescription drugs. The results may be useful in the planning of clinical and regulatory preventive interventions to promote the rational, individualised and safe use of such drugs.

<p>Noble metal nanostructures display collective oscillation of the surface conduction electrons upon light irradiation as a form of localized surface plasmon resonance (LSPR) properties. Size, shape and the refractive index of surrounding environment are the key features that controls the LSPR properties. Surface passivating ligands have the ability to modify the charge density of nanostructures to allow resonant wavelength to match that of the incident light, a phenomenon called “plasmoelectric effect,”. According to the drude model Red and blue shifts of LSPR peak of nanostructures are observed in the event of reducing and increasing charge density, respectively. However, herein we report unusual LSPR properties of gold triangular nanoprisms (Au TNPs) upon functionalization with para-substituted thiophenols (X-Ph-SH, X = -NH₂, -OCH₃, -CH₃, -H, -Cl, -CF₃, and -NO₂). Accordingly, we hypothesized that an appropriate energy level alignment between the Au Fermi energy and the HOMO or LUMO of ligands allows delocalization of surface plasmon excitation at the hybrid inorganic-organic interface, and thus provides a thermodynamically driven plasmoelectric effect. We further validated our hypothesis by calculating the HOMO and LUMO levels and also work function changes of Au TNPs upon functionalization with para substituted thiol. We further utilized our unique finding to design ultrasensitive plasmonic substrate for biosensing of cancer microRNA in bladder cancer and owe to unpresidential sensitivity of the developed Au TNPs based LSPR sensor, for the first time we have been utilized to analysis the tumor suppressor microRNA for more accurate diagnosis of BC. Additionally, we have been advancing our sensing platform to mitigate the false positive and negative responses of the sensing platform using surface enhanced fluorescence technique. This noninvasive, highly sensitive, highly specific, also does not have false positives technique provide strong key to detect cancer at very early stage, hence increase the cancer survival rate. Moreover, the electromagnetic field enhancement of Surface-Enhanced Raman Scattering (SERS) and other related surface-enhanced spectroscopic processes resulted from the LSPR property. This dissertation describes the design and development of entirely new SERS nanosensors using flexible SERS substrate based on unique LSPR property of Au TNPs and developed sensors shows excellent SERS activity (enhancement factor = ~6.0 x 106) and limit of detection (as low as 56 parts-per-quadrillions) with high selectivity by chemometric analyses among three commonly used explosives (TNT, RDX, and PETN). Further we achieved the programable self-assembly of Au TNPs using molecular tailoring to form a 3D supper lattice array based on the substrate effect. Here we achieved the highest reported sensitivity for potent drug analysis, including opioids and synthetic cannabinoids from human plasma obtained from the emergency room. This exquisite sensitivity is mainly due to the two reasons, including molecular resonance of the adsorbate molecules and the plasmonic coupling among the nanoparticles. Altogether we are highly optimistic that our research will not only increase the patient survival rate through early detection of cancer but also help to battle the “war against drugs” that together is expected to enhance the quality of human life. </p> <p> </p>

La France s’inscrit dans une vision idéalisée de la criminalistique dont la force probante apporterait les réponses incontestables au procès pénal. Cette croyance est historique et s’appuie sur les travaux des pionniers français qui ont ouvert la voie à ce que d’aucuns ont appelé, par abus de langage, l’apport de la preuve scientifique. Mais le paysage de la criminalistique n’est pas aussi simple que les acteurs au procès pénal le supposent. Le système criminalistique existant, la formation des intervenants, la connaissance de la valeur informationnelle de la trace avec sa vie juridique comme sa traçabilité scientifique, parfois soumise à un cadre normatif extérieur au droit, sont autant de domaines rarement abordés. À travers les différentes matières composant la criminalistique, en percevoir le contenu et leur puissance scientifique, mais également leurs limites, apportent un éclairage particulier de ce qu’est l’interprétation des résultats analytiques en France, et ce qu’elle devrait être quel que soit le moment judiciaire qu’exige le déroulement de la procédure pénale. Cette présentation met en exergue l’existence de la réalisation d’actes scientifiques souvent négligés et qui vient relativiser la notion d’examens scientifiques et d’expertises pourtant sacralisés par le droit et la jurisprudence. Cette étude de la criminalistique dans le procès pénal, met en évidence la perception qu’en ont les acteurs, la compréhension réciproque difficile avec les experts, mais également celles d’organismes plus institutionnels, montrant que les intérêts sont parfois divergents entre une vision comptable de la justice et celle de la recherche de la vérité, pourtant inscrite dans les textes. Une présentation de la perception comme de la mise en œuvre de la criminalistique en droit comparé à travers la procédure et la jurisprudence accusatoires donne un éclairage sur des débats juridiques qui frappent à la porte de notre système inquisitoire par l’introduction toujours plus engagée du contradictoire. Mieux comprendre les sciences introduites au procès pénal et les rendre accessibles devrait donner aux acteurs une capacité de discernement et d’interprétation plus pertinente, notamment pour les juges qui doivent à partir de toutes ces connaissances, indices et réponses scientifiques en construire la preuve pénale. / France believes in an idealized vision of forensic science, the probative force of which would provide incontestable answers to the criminal trial. This belief is historical and is based on the work of the French pioneers who paved the way for what some have called, by abuse of language, the contribution of scientific proof. But the forensic landscape is not as simple as the actors in the criminal trial assume. Existing forensic systems, training of stakeholders, knowledge of the informational value of the trace with its legal life as well as its scientific traceability, sometimes subject to a normative framework outside the law are all rarely dealt with. Through the various subjects of forensic science, by perceiving their content and their scientific power, but also by their limitations, they shed particular light on the interpretation of analytical results in France and what it should be the judicial time required for the conduct of criminal proceedings. This presentation highlights the existence of the realization of scientific acts often neglected and that relativizes the notion of scientific examinations and expert appraisals yet sacred by law and jurisprudence. This study of criminalistic in the criminal trial highlights the perception of the actors, the difficult mutual understanding with the experts, but also those of more institutional administrations, showing that the interests are sometimes divergent between an accounting vision Justice and the search for truth, which is nevertheless inscribed in the texts. A presentation of the perception as well as the implementation of forensic science in comparative law through accusatory procedure and jurisprudence sheds light on legal debates that strike the door of our inquisitorial system by the increasingly engaged introduction of contradictory. A better understanding of the sciences introduced into the criminal process and making them accessible should give the actors a more relevant capacity for discernment and interpretation, in particular for judges who must draw up the criminal proof from all these scientific knowledge, answers and evidences.

This diploma thesis is about forensic science, criminal acts and organization of protective security units investigating such activities in the former Czechoslovakia between the years of 1948 and 1969. It also indicates how the criminal activity was developed in the Czechoslovakia and how the former police departments took part in the investigation. The course of the investigation, the crime investigation methods, and the theoretical bases of that time, on which the forensic science was based, are thoroughly described on specific serious crimes. The thesis mainly draws from the primary resources such as archive research, notably from the Security Service Archive's materials, and the periodical press.

The Macintosh Hierarchical File System Plus, HFS +, or as it is commonly referred to as the Mac Operating System, OS, Extended, was introduced in 1998 with Mac OS X 8.1. HFS+ is an update to HFS, Mac OS Standard format that offers more efficient use of disk space, implements international friendly file names, future support for named forks, and facilitates booting on non-Mac OS operating systems through different partition schemes. The HFS+ file system is efficient, yet, complex. It makes use of B-trees to implement key data structures for maintaining meta-data about folders, files, and data. The implementation of what happens within HFS+ at volume format, or when folders, files, and data are created, moved, or deleted is largely a mystery to those who are not programmers. The vast majority of information on this subject is relegated to documentation in books, papers, and online content that direct the reader to C code, libraries, and include files. If one can’t interpret the complex C or Perl code implementations the opportunity to understand the workflow within HFS+ is less than adequate to develop a basic understanding of the internals and how they work. The basic concepts learned from this research will facilitate a better understanding of the HFS+ file system and journal as changes resulting from the adding and deleting files or folders are applied in a controlled, easy to follow, process. The primary tool used to examine the file system changes is a proprietary command line interface, CLI, tool called fileXray. This tool is actually a custom implementation of the HFS+ file system that has the ability to examine file system, meta-data, and data level information that iv isn’t available in other tools. We will also use Apple’s command line interface tool, Terminal, the WinHex graphical user interface, GUI, editor, The Sleuth Kit command line tools and DiffFork 1.1.9 help to document and illustrate the file system changes. The processes used to document the pristine and changed versions of the file system, with each experiment, are very similar such that the output files are identical with the exception of the actual change. Keeping the processes the same enables baseline comparisons using a diff tool like DiffFork. Side by side and line by line comparisons of the allocation, extents overflow, catalog, and attributes files will help identify where the changes occurred. The target device in this experiment is a two-gigabyte Universal Serial Bus, USB, thumb drive formatted with Global Unit Identifier, GUID, and Partition Table. Where practical, HFS+ special files and data structures will be manually parsed; documented, and illustrated.

Fire debris analysis currently relies on visual pattern recognition of the total ion chromatograms, extracted ion profiles, and target compound chromatograms to identify the presence of an ignitable liquid. This procedure is described in the ASTM International E1618-10 standard method. For large data sets, this methodology can be time consuming and is a subjective method, the accuracy of which is dependent upon the skill and experience of the analyst. This research aimed to develop an automated classification method for large data sets and investigated the use of the total ion spectrum (TIS). The TIS is calculated by taking an average mass spectrum across the entire chromatographic range and has been shown to contain sufficient information content for the identification of ignitable liquids. The TIS of ignitable liquids and substrates were compiled into model data sets. Substrates are defined as common building materials and household furnishings that are typically found at the scene of a fire and are, therefore, present in fire debris samples. Fire debris samples were also used which were obtained from laboratory-scale and large-scale burns. An automated classification method was developed using computational software that was written in-house. Within this method, a multi-step classification scheme was used to detect ignitable liquid residues in fire debris samples and assign these to the classes defined in ASTM E1618-10. Classifications were made using linear discriminant analysis, quadratic discriminant analysis (QDA), and soft independent modeling of class analogy (SIMCA). The model data sets iv were tested by cross-validation and used to classify fire debris samples. Correct classification rates were calculated for each data set. Classifier performance metrics were also calculated for the first step of the classification scheme which included false positive rates, true positive rates, and the precision of the method. The first step, which determines a sample to be positive or negative for ignitable liquid residue, is arguably the most important in the forensic application. Overall, the highest correct classification rates were achieved using QDA for the first step of the scheme and SIMCA for the remaining steps. In the first step of the classification scheme, correct classification rates of 95.3% and 89.2% were obtained using QDA to classify the crossvalidation test set and fire debris samples, respectively. For this step, the cross-validation test set resulted in a true positive rate of 96.2%, a false positive rate of 9.3%, and a precision of 98.2%. The fire debris data set had a true positive rate of 82.9%, a false positive rate of 1.3%, and a precision of 99.0%. Correct classifications rates of 100% were achieved for both data sets in the majority of the remaining steps which used SIMCA for classification. The lowest correct classification rate, 69.2%, was obtained for the fire debris samples in one of the final steps in the classification scheme. In this research, the first statistically valid error rates for fire debris analysis have been developed through cross-validation of large data sets. The fire debris analyst can use the automated method as a tool for detecting and classifying ignitable liquid residues in fire debris samples. The error rates reduce the subjectivity associated with the current methods and provide a level of confidence in sample classification that does not currently exist in forensic fire debris analysis.

La reconstruction faciale permet d’approximer un visage sur la base d’un crâne, lorsque des restes humains sont retrouvés. En science forensique, elle est l’un des outils utilisés dans un but d’identification post-mortem. Les procédures actuelles d’approximation ne sont pas standardisées et constamment revisitées. Il est également possible d’obtenir des prédictions du phénotype d’un individu (caractères physiques apparents) à partir de son ADN, qui pourraient être ajoutées aux reconstructions pour maximiser les chances de reconnaissance. Cette recherche vise à étudier l’approximation faciale à des fins de reconnaissance et l’apport du phénotypage par l’ADN à cette pratique. Le crâne et le relevé biologique d’un donneur du laboratoire d’anatomie de l’UQTR ont été utilisés. Six praticiens ont approximé son visage à partir d’une copie de son crâne et de ses données phénotypiques et anthropologiques. Les résultats corroborent qu’il existe un manque de standardisation des méthodes et techniques, menant à différents résultats selon le praticien. Des tests de reconnaissance et de ressemblance ont été effectués à l’aide d’un échantillon de 46 participants. Malgré la variabilité des approximations, elles ont toutes été reconnues au moins une fois lors des tests de reconnaissance, soulevant la possibilité que la reconnaissance d’un visage est idiosyncratique. Les caractéristiques qui semblent influencer davantage la reconnaissance sont la forme, la taille et la position des yeux, de la bouche et du nez. Finalement, au regard des incertitudes propres à la méthode et du rôle investigatif de l’approximation faciale, il est recommandé que le phénotypage accompagne l’accompagne par écrit. / Facial reconstruction is a process by which a face is approximated from a skull when human remains are found. In forensic science, it is one of the many tools used for the purpose of post-mortem identification. The current approximation procedures are not standardized and are always revisited. Nowadays, it is possible to obtain phenotype (apparent physical traits) predictions from an individual’s DNA. These predictions could be added to facial approximations to maximize the chances of recognition. This research aims to study facial approximation for recognition purposes and the plus-value of DNA phenotyping to facial approximation. The skull and biological material from one donor of the UQTR’s anatomy laboratory were used. Six practitioners approximated the donor’s face using a copy of his skull, and phenotyping and anthropological data. The results corroborated the lack of standardization regarding the approximating methods and techniques, which leads to different resulting approximations depending on the practitioner. Recognition and resemblance tests were carried out with a sample of 46 participants. Despite the wide variability of the approximations, they were all recognized at least once during the recognition tests, raising the possibility that the recognition of a face is idiosyncratic. The characteristics that seemed the most important to recognition were the shape, size and position of the eyes, the mouth, and the nose. Finally, with regard to the uncertainties specific to the method and the final investigative role of facial approximation, phenotyping would benefit in feeding a spoken portrait.
