The issue of developing a uniform language for international communication in the feld of forensic science is considered. The matters of relative maturity of domestic forensic expert terminology and peculiarities of translated terms usage in forensic expertology and forensic practice are discussed. The concept of expertise subject formulated by modern leading scientists is analyzed, the conclusion is made about the subject of forensic examination as a process of establishing facts and circumstances, the purely applied nature of the concept, as well as the similarity to the defnition of expertise in the ISO international standard. Specifc examples are given. The need to translate some foreign standards into Russian and to adjust and implement several of their provisions in domestic legal system and expert practice to standardize forensic and expert activity is emphasized.

We know from experience that the language of the general theory of forensic science, like any science, is an extremely complex and diverse phenomenon. This language is characterized by specific “constructs” that arise as a result of specialized activity and can be effectively applied not only in the context of the conceptual theoretical framework of forensic science, but also by enforcement professionals in their daily practice. In order to ensure clarity, accuracy and accessibility of expressions in the language of the general theory of forensic science, to avoid polysemy of terms, vagueness and ambiguity of their content, and equivocality of expressions, special attention should be paid to the logical semantic processes in terminology inherent in this language. At the same time, questions need to be raised and addressed about the development of a general concept of terminological activity and the need to regulate and standardize both domestic and international terminology used in forensic expert practice.

While post-mortem angiography (PMA) is gradually establishing its role in Forensic Radiology, the available literature in Italy lacks a solid foundation, particularly regarding its use in criminal court proceedings. An illustrative example of multiphase post-mortem CT angiography (MPMCTA) is presented here to encourage the systematic implementation of PMA methods. To demonstrate concordance between MPMCTA and the reference standard (autopsy and histology) in a case of acute coronary thrombosis, we report a case where MPMCTA, autopsy, histological and toxicological analyses were performed on a previously healthy 51-year-old man. MPMCTA detected a right coronary artery filling defect that could be ascribed to coronary thrombosis, which was later confirmed by autopsy and histological examinations.

AbstractWider dissemination of medical digital video libraries is affected by two correlated factors, resource effective content compression that directly influences its diagnostic credibility. It has been proved that it is possible to meet these contradictory requirements halfway for long-lasting and low motion surgery recordings at compression ratios close to 100 (bronchoscopic procedures were a case study investigated). As the main supporting assumption, it has been accepted that the content can be compressed as far as clinicians are not able to sense a loss of video diagnostic fidelity (a visually lossless compression).Different market codecs were inspected by means of the combined subjective and objective tests toward their usability in medical video libraries. Subjective tests involved a panel of clinicians who had to classify compressed bronchoscopic video content according to its quality under the bubble sort algorithm. For objective tests, two metrics (hybrid vector measure and hosaka Plots) were calculated frame by frame and averaged over a whole sequence.

This document presents a case study of acoustic analysis in an open-plan office. Since Mexico does not have a standard for evaluating acoustic conditions in offices, it is relevant to compare different acoustic evaluation methods used for open-plan offices. According to several studies, one of the main acoustic characteristics for open-plan office spaces is speech intelligibility. Therefore, the purpose of this document is to compare psychoacoustic parameters to evaluate speech intelligibility in open-plan offices. We analyzed physical factors as reverberation and speech clarity in different office points, as well as semantic factors based on subjective methods with standardized values of the quality of speech intelligibility. The study was carried out under real open-plan office conditions in a library in a university in northern Mexico. The study factors of interest were type of sound, sound source, and location of the listener, with Reverberation Time (RT), Speech Transmission Index (STI) and Loss of consonant articulation (%ALCons) as the measures of impact on intelligibility. This case study provides additional evidence of the relationship between intelligibility and the position of sound sources; also, it was noted that location of listeners influenced analyzed intelligibility parameters. On the other hand, this case study offers information concerning to use psychoacoustic parameters for subjective classification of quality of the speech intelligibility to evaluate how is background noise perceived in open-plan office users. However, it is noteworthy that this study represents a single office with its own interior and space design characteristics.

Design Guidance

Researchers in the area of design for the developing world have synthesized knowledge from location-specific product case studies in the form of design guidance, which includes pitfalls, principles, and methods. Much of the design guidance relates to specific product classes and regions, while recent work is directed towards generalized principles. The aim of this paper is to fill gaps in product class-specific design guidance by creating larger groups of similar products, which share design characteristics. In this paper, we present a method for classifying products into such groups utilizing cluster analysis. We present a five-step method, which includes optional synthesis of design principles. The potential value of the method is demonstrated in a case study. The result included two distinct product groups, titled Products for Relief and Products for Development, and corresponding design principles for each group.

<p>Peer-tutoring sessions of two groups of advanced diploma in financial accounting students with mixed proficiency were analysed thoroughly in this study. Numerous studies in peer tutoring have produced favourable results to both tutors and tutees due to the scaffolding process which promotes effective learning. However, there is a lack of studies conducted using case study as a group task in peer tutoring. Therefore, in this study, the analysis of this type of task in the course of peer tutoring is given much prominence. Video recordings of the peer-tutoring sessions were made and informants were interviewed and wrote journals in order to obtain data to be analysed. The researcher’s observation notes were useful in increasing understanding of the group process. The findings revealed that there were similarities and differences pertaining to the teaching and learning experiences encountered by both tutors and tutees when analysing the two case studies. Therefore, appropriate case studies which match students’ abilities are recommended to be used in peer tutoring. Furthermore, regular guidance provided by instructors for tutors is crucial in developing their confidence in playing their role.<strong> </strong></p>

Purpose – This paper aims to investigate the ways that could enhance residents’ social interaction in low-rise residential building neighbourhoods of Basra city in Iraq. The lack of social interaction among residents of Basra city prompted the authors to frame a strategy for this case study. Design/methodology/approach – The spatial design characteristics of low-rise residential building neighbourhoods implicated to support the residents in terms of social interactions in comparison to those exhibited by a single home and traditional neighbourhoods. The statistical data demonstrated that by using this strategy, several unique features of secured, collective, responsive and supportive spaces could enhance the residents’ social interaction. Findings – This study found that all collective space factors have a significant influence on social interaction. “Fostering proper proximity and accessibility” factor was ranked first and the most significant factor with an influence on social interaction. Secured spaces (hierarchical spatial structure, physical security supports and construct) have a significant influence on social interaction. The most interesting finding in this study is that all factors of the supportive spaces construct have a significant influence on social interaction. Finally, this study showed that two factors of the responsive spaces construct, increasing variety and increasing legibility, have an insignificant influence on social interaction. Originality/value – The design of low-rise residential building neighbourhoods in Basra city may be used to develop social interaction as the contributing factor for maintaining values of traditional neighbourhood communities. This study highlights certain recommendations for architects, especially urban designers, to reinforce residents’ social interaction in low-rise residential building neighbourhoods in Basra city.
