    Research and Development ('R&D') in forensic science currently focuses on innovative technologies improving the efficiency of existing forensic processes, from the detection of marks and traces at the scene, to their presentation in Court. R&D approached from this perspective provides no response to doubts raised by recent criminological studies, which question the effective contribution of forensic science to crime reduction, and to policing in general. Traces (i.e. forensic case data), as remnants of criminal activity are collected and used in various forms of crime monitoring and investigation. The aforementioned doubts therefore need to be addressed by expressing how information is conveyed by traces in these processes. Modelling from this standpoint expands the scope of forensic science and provides new R&D opportunities. Twelve propositions for R&D are stated in order to pave the way.

    Human factors and their implications for forensic science have attracted increasing levels of interest across criminal justice communities in recent years. Initial interest centred on cognitive biases, but has since expanded such that knowledge from psychology and cognitive science is slowly infiltrating forensic practices more broadly. This article highlights a series of important findings and insights of relevance to forensic practitioners. These include research on human perception, memory, context information, expertise, decision-making, communication, experience, verification, confidence, and feedback. The aim of this article is to sensitise forensic practitioners (and lawyers and judges) to a range of potentially significant issues, and encourage them to engage with research in these domains so that they may adapt procedures to improve performance, mitigate risks and reduce errors. Doing so will reduce the divide between forensic practitioners and research scientists as well as improve the value and utility of forensic science evidence.

    van Asten, Arian C

    2014-03-01

    In this paper the insights and results are presented of a long term and ongoing improvement effort within the Netherlands Forensic Institute (NFI) to establish a valuable innovation programme. From the overall perspective of the role and use of forensic science in the criminal justice system, the concepts of Forensic Information Value Added (FIVA) and Forensic Information Value Efficiency (FIVE) are introduced. From these concepts the key factors determining the added value of forensic investigations are discussed; Evidential Value, Relevance, Quality, Speed and Cost. By unravelling the added value of forensic science and combining this with the future needs and scientific and technological developments, six forensic grand challenges are introduced: i) Molecular Photo-fitting; ii) chemical imaging, profiling and age estimation of finger marks; iii) Advancing Forensic Medicine; iv) Objective Forensic Evaluation; v) the Digital Forensic Service Centre and vi) Real time In-Situ Chemical Identification. Finally, models for forensic innovation are presented that could lead to major international breakthroughs on all these six themes within a five year time span. This could cause a step change in the added value of forensic science and would make forensic investigative methods even more valuable than they already are today. © 2013.

  11. Nanoparticles in forensic science

    Cantu, Antonio A.

    2008-10-01

    Nanoparticles appear in several areas of forensic science including security documents, paints, inks, and reagents that develop latent prints. One reagent (known as the silver physical developer) that visualizes the water insoluble components of latent print residue is based on the formation of highly charged silver nanoparticles. These attach to and grow on the residue and generate a silver image. Another such reagent involves highly charged gold nanoparticles. These attach to the residue forming a weak gold image which can be amplified with a silver physical developer. Nanoparaticles are also used in items such as paints, printing inks, and writing inks. Paints and most printing inks consist of nano-sized pigments in a vehicle. However, certain modern ink jet printing inks now contain nano-sized pigments to improve their light fastness and most gel inks are also based on nano scale pigments. These nanoparticlecontaining materials often appear as evidence and are thus subject to forensic characterization. Both luminescent (quantum dots), up-converting nano scale phosphors, and non luminescent nanoparticles are used as security tags to label product, add security to documents, and as anti counterfeiting measures. These assist in determining if an item is fraudulently made.

  12. Biosensors in forensic sciences

    Directory of Open Access Journals (Sweden)

    Frederickx, C.

    2011-01-01

    Full Text Available A biosensor is a device that uses biological materials to detect and monitor the presence of specific chemicals in an area. Traditional methods of volatile detection used by law enforcement agencies and rescue teams typically consist of reliance on canine olfaction. This concept of using dogs to detect specific substances is quite old. However, dogs have some limitations such as cost of training and time of conditioning. Thus, the possibility of using other organisms as biosensors including rats, dolphins, honeybees, and parasitic wasps for detecting explosives, narcotics and cadavers has been developed. Insects have several advantages unshared by mammals. Insects are sensitive, cheap to produce and can be conditioned with impressive speed for a specific chemical-detection task. Moreover, insects might be a preferred sensing method in scenarios that are deemed too dangerous to use mammals. The purpose of this review is to provide an overview of the biosensors used in forensic sciences.

  13. Parasites in Forensic Science: a historic perspective

    Science.gov (United States)

    Cardoso, Rita; Alves, Helena; Richter, Joachim; Botelho, Monica C

    Parasites show a great potential to Forensic Science. Forensic Science is the application of any science and methodology to the legal system. The forensic scientist collects and analyses the physical evidence and produce a report of the results to the court. A parasite is an organism that lives at the expense of another and they exist in any ecosystem. Parasites are the cause of many important diseases. The forensic scientists can use the parasites to identify a crime scene, to determine the murder weapon or simply identify an individual. The applications for parasites in the Forensic Science can be many and more studies should be made in Forensic Parasitology. The most important parasites in Forensic Science are helminths specifically schistosomes. Through history there are many cases where schistosomes were described in autopsies and it was related to the cause of death. Here we review the applications of parasites in Forensic Science and its importance to the forensic scientist.

  18. New psychoactive substances: catalysing a shift in forensic science practice?

    Science.gov (United States)

    Tettey, Justice; Crean, Conor

    2015-08-05

    The analysis of substances of abuse remains one of the most matured areas in forensic science with a strong scientific basis, namely analytical chemistry. The current evolving drug markets, characterized by the global emergence of new psychoactive substances (NPS) and the need for forensic scientists to identify an unprecedented and ever-increasing number of NPS, presents a unique challenge to this discipline. This article looks at the current situation with NPS at the global level, and the challenges posed to the otherwise technically robust forensic science discipline of analysis of substances of abuse. It discusses the preparedness of forensic science to deal with the current situation and identifies the need for a shift in forensic science practice, especially one which embraces research and looks beyond normal casework in order to provide the much needed data for developing effective policy responses to the NPS problem. © 2015 The Author(s) Published by the Royal Society.

  19. Forensic culture as epistemic culture: the sociology of forensic science.

    Science.gov (United States)

    Cole, Simon A

    2013-03-01

    This paper explores whether we can interpret the notion of 'forensic culture' as something akin to what Knorr-Cetina called an 'epistemic culture'. Can we speak of a 'forensic culture', and, if so, how is it similar to, or different from, other epistemic cultures that exist in what is conventionally called 'science'? This question has important policy implications given the National Academy Science's (NAS) recent identification of 'culture' as one of the problems at the root of what it identified as 'serious deficiencies' in U.S. forensic science and 'scientific culture' as an antidote to those problems. Finding the NAS's characterisation of 'scientific culture' overly general and naïve, this paper offers a preliminary exploration of what might be called a 'forensic culture'. Specifically, the paper explores the way in which few of the empirical findings accumulated by sociologists of science about research science seem to apply to forensic science. Instead, forensic science seems to have developed a distinct culture for which a sociological analysis will require new explanatory tools. Faithful sociological analysis of 'forensic culture' will be a necessary prerequisite for the kind of culture change prescribed by external reformist bodies like the NAS. Copyright © 2012.

  20. Peer review in forensic science.

    Ballantyne, Kaye N; Edmond, Gary; Found, Bryan

    2017-08-01

    Peer review features prominently in the forensic sciences. Drawing on recent research and studies, this article examines different types of peer review, specifically: editorial peer review; peer review by the scientific community; technical and administrative review; and verification (and replication). The article reviews the different meanings of these quite disparate activities and their utility in relation to enhancing performance and reducing error. It explains how forensic practitioners should approach and use peer review, as well as how it should be described in expert reports and oral testimony. While peer review has considerable potential, and is a key component of modern quality management systems, its actual value in most forensic science settings has yet to be determined. In consequence, forensic practitioners should reflect on why they use specific review procedures and endeavour to make their actual practices and their potential value transparent to consumers; whether investigators, lawyers, jurors or judges. Claims that review increases the validity of a scientific technique or accuracy of opinions within a particular case should be avoided until empirical evidence is available to support such assertions.

  1. Are UK undergraduate Forensic Science degrees fit for purpose?

    Science.gov (United States)

    Welsh, Charles; Hannis, Marc

    2011-09-01

    In October 2009 Skills for Justice published the social research paper 'Fit for purpose?: Research into the provision of Forensic Science degree programmes in UK Higher Education Institutions.' The research engaged employers representing 95% of UK Forensic Science providers and 79% of UK universities offering Forensic Science or Crime Scene degree programmes. In addition to this, the research collected the views of 430 students studying these degrees. In 2008 there were approximately 9000 people working in the Forensic Science sector in the UK. The research found that the numbers of students studying Forensic Science or Crime Scene degrees in the UK have more than doubled since 2002-03, from 2191 in to 5664 in 2007-08. Over the same period there were twice as many females as males studying for these degrees. The research concluded that Forensic Science degree programmes offered by UK universities were of a good quality and they provided the student with a positive learning experience but the content was not relevant for Forensic Science employers. This echoed similar research by the former Government Department for Innovation, Universities and Skills on graduates from wider science, technology, engineering and mathematics degree programmes. The research also found that 75% of students studying Forensic Science or Crime Scene degrees expected to have a career in the Forensic Science sector, meaning that ensuring these courses are relevant for employers is a key challenge for universities. This paper reflects on the original research and discusses the implications in light of recent government policy. Copyright © 2011 Forensic Science Society. Published by Elsevier Ireland Ltd.

    Microbes are present at every crime scene and have been used as physical evidence for over a century. Advances in DNA sequencing and computational approaches have led to recent breakthroughs in the use of microbiome approaches for forensic science, particularly in the areas of estimating postmortem intervals (PMIs), locating clandestine graves, and obtaining soil and skin trace evidence. Low-cost, high-throughput technologies allow us to accumulate molecular data quickly and to apply sophisticated machine-learning algorithms, building generalizable predictive models that will be useful in the criminal justice system. In particular, integrating microbiome and metabolomic data has excellent potential to advance microbial forensics. Copyright © 2017. Published by Elsevier Ltd.

    Christensen, Angi M; Crowder, Christian M; Ousley, Stephen D; Houck, Max M

    2014-01-01

    The discussion of "error" has gained momentum in forensic science in the wake of the Daubert guidelines and has intensified with the National Academy of Sciences' Report. Error has many different meanings, and too often, forensic practitioners themselves as well as the courts misunderstand scientific error and statistical error rates, often confusing them with practitioner error (or mistakes). Here, we present an overview of these concepts as they pertain to forensic science applications, discussing the difference between practitioner error (including mistakes), instrument error, statistical error, and method error. We urge forensic practitioners to ensure that potential sources of error and method limitations are understood and clearly communicated and advocate that the legal community be informed regarding the differences between interobserver errors, uncertainty, variation, and mistakes. © 2013 American Academy of Forensic Sciences.

  6. Forensic Science Curriculum for High School Students

    Science.gov (United States)

    Burgess, Christiana J.

    Over the last several decades, forensic science---the application of science to civil and criminal legal matters---has become of increasing popularity with the public. The range of disciplines within the field is immense, offering individuals the potential for a unique career, regardless of their specific interests or expertise. In response to this growth, many organizations, both public and private, have recognized the need to create forensic science programs that strive to maintain and enhance the quality of forensic science education. Unfortunately, most of the emphasis placed on developing these materials relates to post-secondary education, and creates a significant lack of forensic science educational materials available in the U.S., especially in Oklahoma. The purpose of this project was to create a high school curriculum that provides the foundation for building a broad, yet comprehensive, overview of the field of forensic science and its associated disciplines. The overall goal was to create and provide course materials to high school teachers in order to increase their knowledge of forensic science such that they are able to teach its disciplines effectively and with accuracy. The Forensic Science Curriculum for High School Students includes sample lesson plans, PowerPoint presentations, and lab activities with step-by-step instructions.

    Forensic science is critical to the administration of justice. The discipline of forensic science is remarkably complex and includes methodologies ranging from DNA analysis to chemical composition to pattern recognition. Many forensic practices developed under the auspices of law enforcement and were vetted primarily by the legal system rather than being subjected to scientific scrutiny and empirical testing. Beginning in the 1990s, exonerations based on DNA-related methods revealed problems with some forensic disciplines, leading to calls for major reforms. This process generated a National Academy of Science report in 2009 that was highly critical of many forensic practices and eventually led to the establishment of the National Commission for Forensic Science (NCFS) in 2013. The NCFS was a deliberative body that catalyzed communication between nonforensic scientists, forensic scientists, and other stakeholders in the legal community. In 2017, despite continuing problems with forensic science, the Department of Justice terminated the NCFS. Just when forensic science needs the most support, it is getting the least. We urge the larger scientific community to come to the aid of our forensic colleagues by advocating for urgently needed research, testing, and financial support.

  9. Animal experimentation in forensic sciences: How far have we come?

    Science.gov (United States)

    Cattaneo, C; Maderna, E; Rendinelli, A; Gibelli, D

    2015-09-01

    In the third millennium where ethical, ethological and cultural evolution seem to be leading more and more towards an inter-species society, the issue of animal experimentation is a moral dilemma. Speaking from a self-interested human perspective, avoiding all animal testing where human disease and therapy are concerned may be very difficult or even impossible; such testing may not be so easily justifiable when suffering-or killing-of non human animals is inflicted for forensic research. In order to verify how forensic scientists are evolving in this ethical issue, we undertook a systematic review of the current literature. We investigated the frequency of animal experimentation in forensic studies in the past 15 years and trends in publication in the main forensic science journals. Types of species, lesions inflicted, manner of sedation or anesthesia and euthanasia were examined in a total of 404 articles reviewed, among which 279 (69.1%) concerned studies involving animals sacrificed exclusively for the sake of the experiment. Killing still frequently includes painful methods such as blunt trauma, electrocution, mechanical asphyxia, hypothermia, and even exsanguination; of all these animals, apparently only 60.8% were anesthetized. The most recent call for a severe reduction if not a total halt to the use of animals in forensic sciences was made by Bernard Knight in 1992. In fact the principle of reduction and replacement, frequently respected in clinical research, must be considered the basis for forensic science research needing animals.

    Teitelbaum, J

    2015-01-01

    Although thousands of search engines and databases are available online, finding answers to specific forensic science questions can be a challenge even to experienced Internet users. Because there is no central repository for forensic science information, and because of the sheer number of disciplines under the forensic science umbrella, forensic scientists are often unable to locate material that is relevant to their needs. The author contends that using six publicly accessible search engines and databases can produce high-quality search results. The six resources are Google, PubMed, Google Scholar, Google Books, WorldCat, and the National Criminal Justice Reference Service. Carefully selected keywords and keyword combinations, designating a keyword phrase so that the search engine will search on the phrase and not individual keywords, and prompting search engines to retrieve PDF files are among the techniques discussed.

    Yılmaz, Erkut; Garipcan, Bora; Patra, Hirak K; Uzun, Lokman

    2017-03-28

    Producing molecular imprinting-based materials has received increasing attention due to recognition selectivity, stability, cast effectiveness, and ease of production in various forms for a wide range of applications. The molecular imprinting technique has a variety of applications in the areas of the food industry, environmental monitoring, and medicine for diverse purposes like sample pretreatment, sensing, and separation/purification. A versatile usage, stability and recognition capabilities also make them perfect candidates for use in forensic sciences. Forensic science is a demanding area and there is a growing interest in molecularly imprinted polymers (MIPs) in this field. In this review, recent molecular imprinting applications in the related areas of forensic sciences are discussed while considering the literature of last two decades. Not only direct forensic applications but also studies of possible forensic value were taken into account like illicit drugs, banned sport drugs, effective toxins and chemical warfare agents in a review of over 100 articles. The literature was classified according to targets, material shapes, production strategies, detection method, and instrumentation. We aimed to summarize the current applications of MIPs in forensic science and put forth a projection of their potential uses as promising alternatives for benchmark competitors.

  16. Cognitive neuroscience in forensic science: understanding and utilizing the human element.

    Science.gov (United States)

    Dror, Itiel E

    2015-08-05

    The human element plays a critical role in forensic science. It is not limited only to issues relating to forensic decision-making, such as bias, but also relates to most aspects of forensic work (some of which even take place before a crime is ever committed or long after the verification of the forensic conclusion). In this paper, I explicate many aspects of forensic work that involve the human element and therefore show the relevance (and potential contribution) of cognitive neuroscience to forensic science. The 10 aspects covered in this paper are proactive forensic science, selection during recruitment, training, crime scene investigation, forensic decision-making, verification and conflict resolution, reporting, the role of the forensic examiner, presentation in court and judicial decisions. As the forensic community is taking on the challenges introduced by the realization that the human element is critical for forensic work, new opportunities emerge that allow for considerable improvement and enhancement of the forensic science endeavour. © 2015 The Author(s) Published by the Royal Society.

    Apart from the journals they produce, scientific societies play an important role in communicating scientific findings and norms to the broader society. The American Association for the Advancement of Science (AAAS) includes among its goals to promote and defend the integrity of science and its use; provide a voice for science on societal issues; promote the responsible use of science in public policy; and increase public engagement with science and technology. AAAS websites and programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (http://www.aaas.org/spp/cstc/wwc/book.htm) and ScienceCareers.org (http://sciencecareers.sciencemag.org), provide tools for scientists to become more directly engaged in effectively communicating their findings and involved in the policy process. Education programs work to build the next generation of scientists and a science-literate public. To bridge the current communication gap between scientists, the public and policymakers, AAAS, like other scientific societies, maintains policy and outreach programs with limited budgets and staff. AAAS works to engage policymakers and provide scientific underpinning to key issues through congressional briefings, meetings, policy briefs, and media outreach. AAAS responds to challenges to accepted scientific findings and processes through op-eds, letters to government officials, resolutions, and Board statements. Some of these initiatives occur on a local level in partnership with local civic leaders, whose endorsement makes them more powerful. On a national scale, they assure that the voice of science is included in the debate. The changing media landscape presents opportunities and challenges for future AAAS endeavors.

  18. Forensic historiography: narratives and science.

    Drukteinis, Albert M

    2014-01-01

    Psychiatrists function, in part, as historians who rely on patient narratives to help them understand presenting mental disorders and explain their causes. Forensic psychiatrists have been skeptical of using narratives, raising concerns about their lack of objectivity and potential for bias. They also have criticized narratives as being more performative than scientific. Recent authors, however, have pointed out that narratives may be helpful in forming forensic opinions and supporting oral testimony, while stressing that their use must be consistent with the ethics espoused by forensic psychiatry. This article reviews the role of narratives in understanding human events and the ubiquitous presence of narratives in the judicial process. It delves into the inescapability of using explicit or implicit narratives in the course of forensic practice, as well as how they may be meaningfully incorporated into evaluations and find expression alongside scientific principles. © 2014 American Academy of Psychiatry and the Law.

  19. Posterior distributions for likelihood ratios in forensic science.

    2016-09-01

    Evaluation of evidence in forensic science is discussed using posterior distributions for likelihood ratios. Instead of eliminating the uncertainty by integrating (Bayes factor) or by conditioning on parameter values, uncertainty in the likelihood ratio is retained by parameter uncertainty derived from posterior distributions. A posterior distribution for a likelihood ratio can be summarised by the median and credible intervals. Using the posterior mean of the distribution is not recommended. An analysis of forensic data for body height estimation is undertaken. The posterior likelihood approach has been criticised both theoretically and with respect to applicability. This paper addresses the latter and illustrates an interesting application area. Copyright © 2016 The Chartered Society of Forensic Sciences. Published by Elsevier Ireland Ltd. All rights reserved.

    2015-08-05

    This article reconsiders the relationship between criminal adjudication and forensic expertise in the light of 'new paradigms' of forensic practice and recent law reform. It briefly summarizes conventional wisdom on the typical shortcomings of forensic science and other expert evidence, as a springboard for a more searching critical diagnosis of longstanding maladies. The fundamentally jurisdictional nature of law is emphasized, and some implications for expert testimony noted. English law's traditionally adversarial model of criminal procedure is then reassessed, taking account of a proper understanding of its normative structure and modern development, and drawing on comparative legal research and theorizing to obtain a more rounded second opinion. In conclusion, some avenues for intelligent prescription are canvassed, highlighting the importance of promoting and facilitating effective communication between experts, lawyers and courts, and prioritizing modest practical remedies over radical surgery. © 2015 The Author(s) Published by the Royal Society.

    "Nothing in science has any value to society if it is not communicated." So goes the 1952 quote from Anne Roe, the noted twentieth century American psychologist and writer. She went on to say that "scientists are beginning to learn their social obligations", and now over 60 years later there is certainly evidence to support her assertions. As scientists, by communicating our research to the general public we not only better inform the tax payer where their money is being spent, but are also able to help put into context the topical environmental challenges and issues that society faces, as well as inspiring a whole new generation of future scientists. This process of communication is very much a two-way street; by presenting our work to people outside of our usual spheres of contemporaries, we expose ourselves to alternative thoughts and insights that can inspire us, as scientists, to take another look at our research from angles that we had never before considered. This work presents the results and experiences from a number of public engagement and outreach activities across the UK, in which geoscientists engaged and interacted with members of the general public. These include the design and implementation of Raspberry Pi based outreach activities for several hundred high school students; the process of running a successful podcast (http://thebarometer.podbean.com); hosting and participating in science events for thousands of members of the general public (e.g. http://www.manchestersciencefestival.com and http://sse.royalsociety.org/2013); and creating a citizen science activity that involved primary school children from across the UK. In communicating their research it is imperative that scientists interact with their audience in an effective and engaging manner, whether in an international conference, a classroom, or indeed down the pub. This work also presents a discussion of how these skills can be developed at an early stage in the careers of a research

    Criminalistics, one of the many sub-divisions of forensic science, is an applied science in which items of evidence are analyzed to provide investigative information and scientific evidence to be used in courts of law. Laboratories associated with governmental public agencies are typically involved in criminal cases as opposed to civil cases, and those types of cases that fall within the jurisdiction of the particular agency. Common analytical divisions within criminalistics laboratories include blood alcohol testing, toxicology, narcotics, questioned documents, biology, firearms, latent fingerprints, physical and trace evidence sections. Specialized field investigative services may be provided in the areas of clandestine drug laboratories and major crimes (firearms, biology, trace, arson/explosives). Forensic science best practice requires the use of non-destructive testing whenever reasonably possible. Several technically difficult situations (bodies and evidence encased in cement and metal) are presented as a challenge to audience.

    The dominant conception of forensic science as a patchwork of disciplines primarily assisting the criminal justice system (i.e. forensics) is in crisis or at least shows a series of anomalies and serious limitations. In recent years, symptoms of the crisis have been discussed in a number of reports by various commentators, without a doubt epitomized by the 2009 report by the US National Academies of Sciences (NAS 2009 Strengthening forensic science in the United States: a path forward). Although needed, but viewed as the solution to these drawbacks, the almost generalized adoption of stricter business models in forensic science casework compounded with ever-increasing normative and compliance processes not only place additional pressures on a discipline that already appears in difficulty, but also induce more fragmentation of the different forensic science tasks, a tenet many times denounced by the same NAS report and other similar reviews. One may ask whether these issues are not simply the result of an unfit paradigm. If this is the case, the current problems faced by forensic science may indicate future significant changes for the discipline. To facilitate broader discussion this presentation focuses on trace evidence, an area that is seminal to forensic science both for epistemological and historical reasons. There is, however, little doubt that this area is currently under siege worldwide. Current and future challenges faced by trace evidence are discussed along with some possible answers. The current situation ultimately presents some significant opportunities to re-invent not only trace evidence but also forensic science. Ultimately, a distinctive, more robust and more reliable science may emerge through rethinking the forensics paradigm built on specialisms, revisiting fundamental forensic science principles and adapting them to the twenty-first century. © 2015 The Author(s) Published by the Royal Society.

    Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster because the age at death, birth date, and year of death as well as gender can guide investigators to the correct identity among a large number of possible matches. Traditional morphological methods used by anthropologists to determine age are often imprecise, whereas chemical analysis of tooth dentin, such as aspartic acid racemization, has shown reproducible and more precise results. In this study, we analyzed teeth from Swedish individuals using both aspartic acid racemization and radiocarbon methodologies. The rationale behind using radiocarbon analysis is that aboveground testing of nuclear weapons during the cold war (1955–1963) caused an extreme increase in global levels of carbon-14 (14C), which has been carefully recorded over time. Forty-four teeth from 41 individuals were analyzed using aspartic acid racemization analysis of tooth crown dentin or radiocarbon analysis of enamel, and 10 of these were split and subjected to both radiocarbon and racemization analysis. Combined analysis showed that the two methods correlated well (R2 = 0.66, p Aspartic acid racemization also showed a good precision with an overall absolute error of 5.4 ± 4.2 years. Whereas radiocarbon analysis gives an estimated year of birth, racemization analysis indicates the chronological age of the individual at the time of death. We show how these methods in combination can also assist in the estimation of date of death of an unidentified victim. This strategy can be of significant assistance in forensic casework involving dead victim identification. PMID:19965905

    We are interested in applying our understanding of actinide chemical structure and bonding to broaden the suite of analytical tools available for nuclear forensic analyses. Uranium- and plutonium-oxide systems form under a variety of conditions, and these chemical species exhibit some of the most complex behavior of metal oxide systems known. No less intriguing is the ability of AnO 2 (An: U, Pu) to form non-stoichiometric species described as AnO 2+x . Environmental studies have shown the value of utilizing the chemical signatures of these actinide oxides materials to understand transport following release into the environment. Chemical speciation of actinide-oxide samples may also provide clues as to the age, source, process history, or transport of the material. The scientific challenge is to identify, measure and understand those aspects of speciation of actinide analytes that carry information about material origin and history most relevant to forensics. Here, we will describe our efforts in material synthesis and analytical methods development that we will use to provide the fundamental science required to characterize actinide oxide molecular structures for forensics science. Structural properties and initial results to measure structural variability of uranium oxide samples using synchrotron-based X-ray Absorption Fine Structure will be discussed.

    During the last years, the individual specialities of forensic medicine and diagnostic imaging have increasingly cooperated to create the interdisciplinary entity of forensic radiology. The book demonstrates the potential of this speciality: It has become evident that the combination of diagnostic imaging and forensic medicine solves more cases of death of unknown cause than each alone, and that a radiograph can be read like a document describing forces of modern time and its effects on current society. The posters of 6 exhibitions demonstrate the actual cause of death and its preceding violence. They aim at the medical as well as the interested lay-public: Causes of natural and of violent death become visible. For instance, stab- and gunshot wounds into a person's rear are contradictory of self-defence. Stab wounds with penetration of ribs indicate great force and, therefore, intentional homicide. The same is valid for multiple stabs, stabs through silicon prosthesis of a mammoplasty, and stabs into the breast cage of a defenceless toddler. X-rays of the living can indicate preceding torture. X-rays are part of the security technology employed at airports and countries' borders. They help to detect drugs, explosives, and human stow-aways. The x-ray examination of the deceased visualises success and failure of the preceding therapy. After reanimation, the position of a tracheal tube, the effects of a vascular puncture, and potential fractures of the breast cage can be evaluated. After cardiac and aortic interventions, the procedure of choice and its effects can be seen. Concerning general or intensive care, diagnostic imaging shows the position of urinary catheters, gastric tubes and vascular catheters. Prenatal diagnostic imaging can determine the sex of the foetus and possible malformations; and in peri- and postnatal death, it may show the effects of iatrogenic actions, and later on, of child-abuse.

    In this paper, the importance of modern technology in forensic investigations is discussed. Recent technological developments are creating new possibilities to perform robust scientific measurements and studies outside the controlled laboratory environment. The benefits of real-time, on-site forensic investigations are manifold and such technology has the potential to strongly increase the speed and efficacy of the criminal justice system. However, such benefits are only realized when quality can be guaranteed at all times and findings can be used as forensic evidence in court. At the Netherlands Forensic Institute, innovation efforts are currently undertaken to develop integrated forensic platform solutions that allow for the forensic investigation of human biological traces, the chemical identification of illicit drugs and the study of large amounts of digital evidence. These platforms enable field investigations, yield robust and validated evidence and allow for forensic intelligence and targeted use of expert capacity at the forensic institutes. This technological revolution in forensic science could ultimately lead to a paradigm shift in which a new role of the forensic expert emerges as developer and custodian of integrated forensic platforms. © 2015 The Author(s) Published by the Royal Society.

    The generation of observations is a technical process and the advances that have been made in forensic science techniques over the last 50 years have been staggering. But science is about reasoning-about making sense from observations. For the forensic scientist, this is the challenge of interpreting a pattern of observations within the context of a legal trial. Here too, there have been major advances over recent years and there is a broad consensus among serious thinkers, both scientific and legal, that the logical framework is furnished by Bayesian inference (Aitken et al. Fundamentals of Probability and Statistical Evidence in Criminal Proceedings). This paper shows how the paradigm has matured, centred on the notion of the balanced scientist. Progress through the courts has not been always smooth and difficulties arising from recent judgments are discussed. Nevertheless, the future holds exciting prospects, in particular the opportunities for managing and calibrating the knowledge of the forensic scientists who assign the probabilities that are at the foundation of logical inference in the courtroom. © 2015 The Author(s) Published by the Royal Society.

    2016-01-01

    Full Text Available Forensic odontology is a branch that connects dentistry and the legal profession. One of the members in the forensic investigation team is a dentist. Dentists play an important and significant role in various aspects of the identification of persons in various forensic circumstances. However, several dentists and legal professionals are quite ignorant of this fascinating aspect of forensic odontology. A need was felt to fill this gap. The dental record is a legal document possessed by the dentist and it contains subjective and objective information about the patient. A PubMed search and Google search were done for articles highlighting the importance of dental records in forensic sciences using the key words "forensic odontology, forensic dentistry, forensic dentists, identification, dental records, and dental chart". A total of 42 articles relevant to the title of the article were found and reviewed. The present article highlights the role of dentists in forensic sciences, their possible contributions to forensics, and the various aspects of forensic dentistry, thus bridging the gap of knowledge between the legal and the dental fraternities.

  4. FTIR spectroscopy applications in forensic science

    1999-01-01

    Infrared spectroscopy, and especially Fourier transform infrared spectroscopy, is a well-established technique in analytical chemistry and finds widespread application in qualitative and quantitative analyses. Infrared spectra depend on the nature of the functional groups present in the analyte, and are generally complex with numerous maxima and minima. These features are useful for comparison purposes and, in most cases, the infrared spectrum of an organic compound is considered as a unique functional print of this compound (i e the infrared spectrum constitutes the chemical signature or fingerprint of an organic compound). Many inorganic substances may also be uniquely identified using infrared spectroscopy. Until recently, infrared spectroscopy was of only limited utility in forensic science, despite its high selectivity. This is because infrared spectroscopy suffered from a lack of sensitivity in its early forms. However, with the advance of modern technology this is no longer the case. The widespread use of microscope attachments, along with numerous new sampling accessories, has overcome most of the previous limitations. For example, with an infrared microscope, it is possible to focus the infrared beam, and therefore select relevant areas of the sample as small as 10 x 10 μm and achieve a measurement in situ. Such a configuration enables the rapid generation of high-resolution spectra from samples of 10 ng. Typical forensic applications include the analysis of single textile fibres, minute paint chips or smears, drugs, laser printer and photocopy toners, polymers and miscellaneous unknown substances. Here we will broadly review the most common applications of infrared spectroscopy in forensic science

  5. Big data in forensic science and medicine.

    Lefèvre, Thomas

    2018-07-01

    In less than a decade, big data in medicine has become quite a phenomenon and many biomedical disciplines got their own tribune on the topic. Perspectives and debates are flourishing while there is a lack for a consensual definition for big data. The 3Vs paradigm is frequently evoked to define the big data principles and stands for Volume, Variety and Velocity. Even according to this paradigm, genuine big data studies are still scarce in medicine and may not meet all expectations. On one hand, techniques usually presented as specific to the big data such as machine learning techniques are supposed to support the ambition of personalized, predictive and preventive medicines. These techniques are mostly far from been new and are more than 50 years old for the most ancient. On the other hand, several issues closely related to the properties of big data and inherited from other scientific fields such as artificial intelligence are often underestimated if not ignored. Besides, a few papers temper the almost unanimous big data enthusiasm and are worth attention since they delineate what is at stakes. In this context, forensic science is still awaiting for its position papers as well as for a comprehensive outline of what kind of contribution big data could bring to the field. The present situation calls for definitions and actions to rationally guide research and practice in big data. It is an opportunity for grounding a true interdisciplinary approach in forensic science and medicine that is mainly based on evidence.

The book explains how the key inventions: agriculture, writing and printing with movable type, initiated an explosive growth of knowledge and human power over the environment. It also shows how the Industrial Revolution changed the relationship between humans and nature, and initiated a massive use of fossil fuels. Problems related to nuclear power, nuclear weapons, genetic engineering, information technology, exhaustion of non-renewable resources, use of fossil fuels and climate change are examined in the later chapters of the book. Finally, the need for ethical maturity to match our scientific progress is discussed.

    In 1998 the organization of the International Union of Soil Sciences (IUSS) was renewed to better support national activities. That was also the new start in the operation of the Finnish Society of Soil Sciences, which became affiliated to the IUSS. The society was originally established in 1971 but it remained relatively inactive. Currently, there are around 200 members in the Finnish Society of Soil Sciences. The members of the executive board cover different fields of soil science from geology to microbiology. Mission statement of the society is to promote the soil sciences and their application in Finland, to act as a forum for creation of better links between soil scientists, interested end users and the public, and to promote distribution and appreciation of general and Finnish research findings in soil science. Every second year the society organizes a national two-day long conference. In 2017 the theme 'circular economy' collected all together 57 presentations. The members of the incoming student division carried responsibility in practical co-ordination committee, acting also as session chairs. In the intervening years the society organizes a weekend excursion to neighboring areas. Lately we have explored the use of biochar in landscaping of Stockholm.

  15. Analysis of errors in forensic science

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Reliability of expert testimony is one of the foundations of judicial justice. Both expert bias and scientific errors affect the reliability of expert opinion, which in turn affects the trustworthiness of the findings of fact in legal proceedings. Expert bias can be eliminated by replacing experts; however, it may be more difficult to eliminate scientific errors. From the perspective of statistics, errors in operation of forensic science include systematic errors, random errors, and gross errors. In general, process repetition and abiding by the standard ISO/IEC:17025: 2005, general requirements for the competence of testing and calibration laboratories, during operation are common measures used to reduce errors that originate from experts and equipment, respectively. For example, to reduce gross errors, the laboratory can ensure that a test is repeated several times by different experts. In applying for forensic principles and methods, the Federal Rules of Evidence 702 mandate that judges consider factors such as peer review, to ensure the reliability of the expert testimony. As the scientific principles and methods may not undergo professional review by specialists in a certain field, peer review serves as an exclusive standard. This study also examines two types of statistical errors. As false-positive errors involve a higher possibility of an unfair decision-making, they should receive more attention than false-negative errors.

    2014-05-01

    Wildlife forensic science may not have attained the profile of human identification, yet the scale of criminal activity related to wildlife is extensive by any measure. Service delivery in the arena of wildlife forensic science is often ad hoc, unco-ordinated and unregulated, yet many of those currently dedicated to wildlife conservation and the protection of endangered species are striving to ensure that the highest standards are met. The genetic markers and software used to evaluate data in wildlife forensic science are more varied than those in human forensic identification and are rarely standardised between species. The time and resources required to characterise and validate each genetic maker is considerable and in some cases prohibitive. Further, issues are regularly encountered in the construction of allelic databases and allelic ladders; essential in human identification studies, but also applicable to wildlife criminal investigations. Accreditation and certification are essential in human identification and are currently being strived for in the forensic wildlife community. Examples are provided as to how best practice can be demonstrated in all areas of wildlife crime analysis and ensure that this field of forensic science gains and maintains the respect it deserves. This review is aimed at those conducting human identification to illustrate how research concepts in wildlife forensic science can be used in the criminal justice system, as well as describing the real importance of this type of forensic analysis.

  17. The current status of forensic science laboratory accreditation in Europe.

    Malkoc, Ekrem; Neuteboom, Wim

    2007-04-11

    Forensic science is gaining some solid ground in the area of effective crime prevention, especially in the areas where more sophisticated use of available technology is prevalent. All it takes is high-level cooperation among nations that can help them deal with criminality that adopts a cross-border nature more and more. It is apparent that cooperation will not be enough on its own and this development will require a network of qualified forensic laboratories spread over Europe. It is argued in this paper that forensic science laboratories play an important role in the fight against crime. Another, complimentary argument is that forensic science laboratories need to be better involved in the fight against crime. For this to be achieved, a good level of cooperation should be established and maintained. It is also noted that harmonization is required for such cooperation and seeking accreditation according to an internationally acceptable standard, such as ISO/IEC 17025, will eventually bring harmonization as an end result. Because, ISO/IEC 17025 as an international standard, has been a tool that helps forensic science laboratories in the current trend towards accreditation that can be observed not only in Europe, but also in the rest of the world of forensic science. In the introduction part, ISO/IEC 17025 states that "the acceptance of testing and calibration results between countries should be facilitated if laboratories comply with this international standard and if they obtain accreditation from bodies which have entered into mutual recognition agreements with equivalent bodies in other countries using this international standard." Furthermore, it is emphasized that the use of this international standard will assist in the harmonization of standards and procedures. The background of forensic science cooperation in Europe will be explained by using an existing European forensic science network, i.e. ENFSI, in order to understand the current status of forensic

    Standards establish specifications and procedures designed to ensure products, services and systems are safe, reliable and consistently perform as intended. Standards can be used in the accreditation of forensic laboratories or facilities and in the certification of products and services. In recent years there have been various international activities aiming at developing forensic science standards and guidelines. The most significant initiative currently underway within the global forensic community is the development of International Organization for Standardization (ISO) standards. This paper reviews the main bodies working on standards for forensic science, the processes used and the implications for accreditation. This paper specifically discusses the work of ISO Technical Committee TC272, the future TC272 work program for the development of forensic science standards and associated timelines. Also discussed, are the lessons learnt to date in navigating the complex environment of multi-country stakeholder deliberations in standards development. Crown Copyright © 2018.

    2010-06-01

    Full Text Available This paper introduces the Digital Records Forensics project, a research endeavour located at the University of British Columbia in Canada and aimed at the development of a new science resulting from the integration of digital forensics with diplomatics, archival science, information science and the law of evidence, and of an interdisciplinary graduate degree program, called Digital Records Forensics Studies, directed to professionals working for law enforcement agencies, legal firms, courts, and all kind of institutions and business that require their services. The program anticipates the need for organizations to become “forensically ready,” defined by John Tan as “maximizing the ability of an environment to collect credible digital evidence while minimizing the cost of an incident response (Tan, 2001.” The paper argues the need for such a program, describes its nature and content, and proposes ways of delivering it.

    Forensic science is a wide field comprising of several subspecialties and uses methods derived from natural sciences for finding criminals and other evidence valid in a legal court. A relatively new area; Nano-forensics brings a new era of investigation in forensic science in which instantaneous results can be produced that determine various agents such as explosive gasses, biological agents and residues in different crime scenes and terrorist activity investigations. This can be achieved by applying Nanotechnology and its associated characterization techniques in forensic sciences. Several characterization techniques exist in Nanotechnology and nano-analysis is one such technique that is used in forensic science which includes Electron microscopes (EM) like Transmission (TEM) and Scanning (SEM), Raman microscopy (Micro -Raman) and Scanning Probe Microscopes (SPMs) like Atomic Force Microscope (AFM). Atomic force microscopy enables surface characterization of different materials by examining their morphology and mechanical properties. Materials that are immeasurable such as hair, body fluids, textile fibers, documents, polymers, pressure sensitive adhesives (PSAs), etc. are often encountered during forensic investigations. This review article will mainly focus on the use of AFM in the examination of different evidence such as blood stains, forged documents, human hair samples, ammunitions, explosives, and other such applications in the field of Forensic Science.

  4. Development of a Bi-Disciplinary Course in Forensic Science

    Directory of Open Access Journals (Sweden)

    Stacey L. Raimondi

    2013-08-01

    Full Text Available Forensic science programs and courses have traditionally been housed within chemistry departments at the college/university level, largely because the pioneers of the field were chemists who applied technology that was more chemical than biological in nature. However, with the development of such areas of study as DNA analysis, anatomical studies, and forensic entomology, it is becoming more and more important for forensic science students to have a strong biological background as well as a chemical background. Furthermore, while biology students are typically required to have extensive chemistry training as part of their major, the converse is not true for chemistry students. Therefore, it is possible that a student interested in forensic science could complete a major in chemistry and never have taken a biology class, leaving them woefully under-prepared for any type of masters program or career in forensic science immediately following graduation. Indeed, an examination of available positions in forensic science shows a large number of positions for DNA analysts for which the typical chemistry student would not be prepared without extensive biology training (http://www.aafs.org. Furthermore, positions for medical examiners or pathologists require extensive training in biology in addition to the continued medical training and residency programs. Therefore, it seems imperative that introductory forensic science courses adapt to these needs and be taught with a more bi-disciplinary approach in order to educate students on the whole field rather than one aspect. To that end, a new bi-disciplinary Forensic Science course was developed at Elmhurst College. This course was team-taught by a biology and a chemistry professor so that students would obtain a thorough understanding of the field and techniques used by both biologists and chemists. A description of this new version of a forensic science course follows, focusing on the addition of biology

    The challenge in achieving an ideal state of justice is that each "proof" has the highest degree of reliability. This is the main responsibility of the forensic scientist. Up to now, criminal investigations in Mexico have been supported by forensic work from a wide variety of disciplinary backgrounds that give testimony in a particular area, even though they may have become forensic witnesses in a complementary and experiential manner. In January 2013, the Universidad Nacional Autónoma de México (UNAM) approved the "Forensic Science" undergraduate program that, in collaboration with various academic entities and government institutions, will develop forensic scientists trained in science, law, and criminology. This is focused on contributing to the national demand that the justice system has more elements to procure and administer justice in dealing with crime.

    Millette, James R; Brown, Richard S; Hill, Whitney B

    2008-01-01

    Environmental forensic microscopy investigations are based on the methods and procedures developed in the fields of criminal forensics, industrial hygiene and environmental monitoring. Using a variety of microscopes and techniques, the environmental forensic scientist attempts to reconstruct the sources and the extent of exposure based on the physical evidence left behind after particles are exchanged between an individual and the environments he or she passes through. This article describes how environmental forensic microscopy uses procedures developed for environmental monitoring, criminal forensics and industrial hygiene investigations. It provides key references to the interdisciplinary approach used in microscopic investigations. Case studies dealing with lead, asbestos, glass fibers and other particulate contaminants are used to illustrate how environmental forensic microscopy can be very useful in the initial stages of a variety of environmental exposure characterization efforts to eliminate some agents of concern and to narrow the field of possible sources of exposure.

    Science.gov (United States)

    Dror, Itiel E.

    2015-01-01

    The human element plays a critical role in forensic science. It is not limited only to issues relating to forensic decision-making, such as bias, but also relates to most aspects of forensic work (some of which even take place before a crime is ever committed or long after the verification of the forensic conclusion). In this paper, I explicate many aspects of forensic work that involve the human element and therefore show the relevance (and potential contribution) of cognitive neuroscience to forensic science. The 10 aspects covered in this paper are proactive forensic science, selection during recruitment, training, crime scene investigation, forensic decision-making, verification and conflict resolution, reporting, the role of the forensic examiner, presentation in court and judicial decisions. As the forensic community is taking on the challenges introduced by the realization that the human element is critical for forensic work, new opportunities emerge that allow for considerable improvement and enhancement of the forensic science endeavour.

    This study aimed to discuss how caring science can contribute and provide a theoretical foundation for the development of caring within forensic psychiatric care. It is not only a challenge but also a great opportunity to use caring science theory within forensic psychiatric care when caring for the patients and supporting their health processes. There is a need for more knowledge about, understanding of, and willingness to care for patients within forensic psychiatric settings in a "true caring" way. In order to achieve this, a caring culture is required, one that supports carers and provides them with opportunities to further develop a caring attitude. © 2014 Wiley Periodicals, Inc.

  18. Conceptualising forensic science and forensic reconstruction. Part I: A conceptual model.

    Science.gov (United States)

    Morgan, R M

    2017-11-01

    There has been a call for forensic science to actively return to the approach of scientific endeavour. The importance of incorporating an awareness of the requirements of the law in its broadest sense, and embedding research into both practice and policy within forensic science, is arguably critical to achieving such an endeavour. This paper presents a conceptual model (FoRTE) that outlines the holistic nature of trace evidence in the 'endeavour' of forensic reconstruction. This model offers insights into the different components intrinsic to transparent, reproducible and robust reconstructions in forensic science. The importance of situating evidence within the whole forensic science process (from crime scene to court), of developing evidence bases to underpin each stage, of frameworks that offer insights to the interaction of different lines of evidence, and the role of expertise in decision making are presented and their interactions identified. It is argued that such a conceptual model has value in identifying the future steps for harnessing the value of trace evidence in forensic reconstruction. It also highlights that there is a need to develop a nuanced approach to reconstructions that incorporates both empirical evidence bases and expertise. A conceptual understanding has the potential to ensure that the endeavour of forensic reconstruction has its roots in 'problem-solving' science, and can offer transparency and clarity in the conclusions and inferences drawn from trace evidence, thereby enabling the value of trace evidence to be realised in investigations and the courts.

    Yadav, Praveen Kumar

    2017-01-01

    Many commentators have acknowledged the fact that the usual courtroom maxim to "tell the truth, the whole truth, and nothing but the truth" is not so easy to apply in practicality. In any given situation, what does the whole truth include? In case, the whole truth includes all the possible alternatives for a given situation, what should a forensic expert witness do when an important question is not asked by the prosecutor? Does the obligation to tell the whole truth mean that all possible, all probable, all reasonably probable, all highly probable, or only the most probable alternatives must be given in response to a question? In this paper, an attempt has been made to review the various ethical issues in different fields of forensic science, forensic psychology, and forensic DNA databases. Some of the ethical issues are common to all fields whereas some are field specific. These ethical issues are mandatory for ensuring high levels of reliability and credibility of forensic scientists.

The Digital Society creates information and numbers from many scientific disciplines. The amassment of data though makes is hard to find structures and requires a skill full analysis of this massive raw material. The thoughts presented here on DS2 - Data Science & Digital Society analyze these challenges and offers ways to handle the questions arising in this evolving context. We propose three levels of analysis and lay out how one can react to the challenges that come about. Concrete examples concern Credit default swaps, Dynamic Topic modeling, Crypto currencies and above all the quantitative analysis of real data in a DS2 context.

  1. The communication of forensic science in the criminal justice system: A review of theory and proposed directions for research.

    Science.gov (United States)

    Howes, Loene M

    2015-03-01

    Clear communication about forensic science is essential to the effectiveness and perceived trustworthiness of the criminal justice system. Communication can be seen as a meaning-making process that involves different components such as the sender of a message, the message itself, the channel in which a message is sent, and the receiver of the message. Research conducted to date on the communication between forensic scientists and non-scientists in the criminal justice system has focused on different components of the communication process as objects of study. The purpose of this paper is to bring together communication theory and past research on the communication of forensic science to contribute to a deeper understanding of it, and to provide a coherent view of it overall. The paper first outlines the broader context of communication theory and science communication as a backdrop to forensic science communication. Then it presents a conceptual framework as a way to organise past research and, using the framework, reviews recent examples of empirical research and commentary on the communication of forensic science. Finally the paper identifies aspects of the communication of forensic science that may be addressed by future research to enhance the effectiveness of communication between scientists and non-scientists in this multidisciplinary arena.

    In today's complex world, we have come to rely increasingly on those who have expertise in specific areas and can bring their knowledge to bear on crucial social, political and scientific questions. Taking the viewpoint that experts are consulted when there is something important at stake for an individual, a group, or society at large, Experts in Science and Society explores expertise as a relational concept. How do experts balance their commitment to science with that to society? How does a society actually determine that a person has expertise? What personal traits are valued in an expert? From where does the expert derive authority? What makes new forms of expertise emerge?

    Buzzini, Patrick; Massonnet, Genevieve

    2010-08-01

    Raman spectroscopy has only recently sparked interest from forensic laboratories. The Raman technique has demonstrated important advantages such as its nondestructive nature, its fast analysis time, and especially the possibility of performing microscopical in situ analyses. In forensic applications, it is a versatile technique that covers a wide spectrum of substances such as trace evidence, illicit drugs and inks. An overview of the recent developments of Raman spectroscopy in forensic science will be discussed. Also, the requirements for an analytical technique for the examination of physical evidence will be described. Examples of casework will be depicted.

    The increased use of social networking is changing the way that scientific societies interact with their members and others. The American Association for the Advancement of Science (AAAS) uses a variety of online networks to engage its members and the broader scientific community. AAAS members and non-members can interact with AAAS staff and each other on AAAS sites on Facebook, YouTube, and Twitter, as well as blogs and forums on the AAAS website (www.aaas.org). These tools allow scientists to more readily become engaged in policy by providing information on current science policy topics as well as methods of involvement. For example, members and the public can comment on policy-relevant stories from Science magazine’s ScienceInsider blog, download a weekly policy podcast, receive a weekly email update of policy issues affecting the scientific community, or watch a congressional hearing from their computer. AAAS resource websites and outreach programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (www.aaas.org/spp/cstc/) and Science Careers (http://sciencecareers.sciencemag.org) also provide tools for scientists to become more personally engaged in communicating their findings and involved in the policy process.

    Forensic Science is oriented towards the examination of evidence specimens, collected from a scene of crime in order to establish the link between the criminal and the crime. This science therefore has a profound role to play in criminal justice delivery system. The importance of neutron activation analysis (NAA) as a specialised technique to aid crime investigation has emerged and has been recognised

  8. Forensic nursing science knowledge and competency: the use of simulation.

    2015-01-01

    Forensic nursing is a nursing specialty that provides services to a variety of patient populations who have experienced violence, including interpersonal violence, sudden or unexpected death, and motor vehicle collisions. However, many critical care nurses have received the background knowledge or practical skills required to provide the level of care required by many forensic patients. The purpose of this study was to determine whether differences in knowledge or practical competence exist between participants using 2 different learning modalities: medium fidelity simulation versus face-to-face lecture. Participants who were enrolled in an elective online forensic nursing science course were randomly assigned to an intervention or control group. The 18 intervention group participants were given three 2-hour forensic simulation sessions in the laboratory. The 17 control group participants attended 3 face-to-face lectures covering forensic science topics. All study participants also received the same forensic course content via the online Blackboard platform. No significant differences were found between the 2 groups in either knowledge or practical competency. The lack of results may have been heavily influenced by the small sample size, which resulted in insufficient power to detect possible differences.

    The International Association of Forensic Nurses (IAFN) is the only nursing organization advancing the forensic nursing specialty. The organization seeks to advance the profession, and one mechanism for doing so is development of a research agenda. The purpose of this action-based research study was to aid in the development of a forensic nursing research agenda. The study was carried out in two integral stages: (a) focus groups with IAFN members attending the annual conference and (b) reviewing posted IAFN member listserv material. The findings of this study identified similar gaps of other nursing specialties experiencing "growing pains," including role confusion and variation in educational preparation. Findings from this study will inform development of the IAFN 5-year research agenda to advance forensic nursing science and evidence-based practice.

  10. A forensic science perspective on the role of images in crime investigation and reconstruction.

    Science.gov (United States)

    Milliet, Quentin; Delémont, Olivier; Margot, Pierre

    2014-12-01

    This article presents a global vision of images in forensic science. The proliferation of perspectives on the use of images throughout criminal investigations and the increasing demand for research on this topic seem to demand a forensic science-based analysis. In this study, the definitions of and concepts related to material traces are revisited and applied to images, and a structured approach is used to persuade the scientific community to extend and improve the use of images as traces in criminal investigations. Current research efforts focus on technical issues and evidence assessment. This article provides a sound foundation for rationalising and explaining the processes involved in the production of clues from trace images. For example, the mechanisms through which these visual traces become clues of presence or action are described. An extensive literature review of forensic image analysis emphasises the existing guidelines and knowledge available for answering investigative questions (who, what, where, when and how). However, complementary developments are still necessary to demystify many aspects of image analysis in forensic science, including how to review and select images or use them to reconstruct an event or assist intelligence efforts. The hypothetico-deductive reasoning pathway used to discover unknown elements of an event or crime can also help scientists understand the underlying processes involved in their decision making. An analysis of a single image in an investigative or probative context is used to demonstrate the highly informative potential of images as traces and/or clues. Research efforts should be directed toward formalising the extraction and combination of clues from images. An appropriate methodology is key to expanding the use of images in forensic science.

    Personalized medicine (PM), included in P5 medicine (Personalized, Predictive, Preventive, Participative and Precision medicine) is an innovative approach to the patient, emerging from the need to tailor and to fit the profile of each individual. PM promises to dramatically impact also on forensic sciences and justice system in ways we are only beginning to understand. The application of omics (genomic, transcriptomics, epigenetics/imprintomics, proteomic and metabolomics) is ever more fundamental in the so called "molecular autopsy". Emerging fields of interest in forensic pathology are represented by diagnosis and detection of predisposing conditions to fatal thromboembolic and hypertensive events, determination of genetic variants related to sudden death, such as congenital long QT syndromes, demonstration of lesions vitality, identification of biological matrices and species diagnosis of a forensic trace on crime scenes without destruction of the DNA. The aim of this paper is to describe the state-of-art in the application of personalized medicine in forensic sciences, to understand the possibilities of integration in routine investigation of these procedures with classical post-mortem studies and to underline the importance of these new updates in medical examiners' armamentarium in determining cause of death or contributing factors to death.

    In an era where noninvasive and minimally invasive techniques are heralding medical innovations and health science technology, necrological analysis is not bereft of this wave. Virtopsy is virtual autopsy. It is a new-age complimentary documentation approach to identify and analyze the details of demise. Utilizing virtual autopsy for orofacial forensic examination is an emerging specialty which holds a plethora of potential for future trends in forensic science. Being a noninvasive technique, it is a rapid method which facilitates the medicolegal process and aids in the delivery of justice. The present article is an overview of this emerging methodology.

  14. Forensic fictions: science, television production, and modern storytelling.

    Science.gov (United States)

    Kirby, David A

    2013-03-01

    This essay uses interviews with television creators, writers, and producers to examine how media practitioners utilise, negotiate and transform forensic science in the production of televisual stories including the creation of unique visuals, character exploration, narrative progression, plot complication, thematic development, and adding a sense of authenticity. Television as a medium has its own structures and conventions, including adherence to a show's franchise, which put constraints on how stories are told. I demonstrate how television writers find forensic science to be an ideal tool in navigating television's narrative constraints by using forensics to create conflicts, new obstacles, potential solutions, and final solutions in their stories. I show how television writers utilise forensic science to provide the scientific certainty their characters require to catch the criminal, but also how uncertainty is introduced in a story through the interpretation of the forensics by the show's characters. I also argue that televisual storytellers maintain a flexible notion of scientific realism based on the notion of possibility that puts them at odds with scientists who take a more demanding conception of scientific accuracy based on the concept of probability.

  15. Distinguishing between forensic science and forensic pseudoscience: testing of validity and reliability, and approaches to forensic voice comparison.

    Science.gov (United States)

    Morrison, Geoffrey Stewart

    2014-05-01

    In this paper it is argued that one should not attempt to directly assess whether a forensic analysis technique is scientifically acceptable. Rather one should first specify what one considers to be appropriate principles governing acceptable practice, then consider any particular approach in light of those principles. This paper focuses on one principle: the validity and reliability of an approach should be empirically tested under conditions reflecting those of the case under investigation using test data drawn from the relevant population. Versions of this principle have been key elements in several reports on forensic science, including forensic voice comparison, published over the last four-and-a-half decades. The aural-spectrographic approach to forensic voice comparison (also known as "voiceprint" or "voicegram" examination) and the currently widely practiced auditory-acoustic-phonetic approach are considered in light of this principle (these two approaches do not appear to be mutually exclusive). Approaches based on data, quantitative measurements, and statistical models are also considered in light of this principle. © 2013.

  17. Palynology: its position in the field of forensic science.

    Science.gov (United States)

    Walsh, Kevan A J; Horrocks, Mark

    2008-09-01

    Here we examine the current state of palynology in the field of forensic science. Forensic palynology is discussed with reference to other forensic disciplines to help understand what is required for its progress. Emerging developments are also discussed. Palynomorphs potentially deliver excellent trace evidence, fulfilling the requirements relating to the transfer, persistence, and detection of such evidence. Palynological evidence can provide very powerful investigative and associative evidence. Despite this, the application of palynology to forensic science has had mixed success. There are many anecdotal stories where pollen evidence has had spectacular successes. But it is extremely underutilized in most countries because it is labor-intensive and requires considerable expertise and experience, there is a lack of control over sample collection and inadequate resourcing and funding, and its crime-solving power is not well known. Palynology has been applied to forensic problems in an unstructured way, resulting in a lack of formalized discussion of the underlying principles. As there is renewed questioning of the acceptability of most evidence types in the current legal environment, there is a need for the establishment of palynological evidence through validation-type studies and experimentation, and the implementation of independent proficiency testing.

  18. Renegotiating forensic cultures: between law, science and criminal justice.

    Science.gov (United States)

    Roberts, Paul

    2013-03-01

    This article challenges stereotypical conceptions of Law and Science as cultural opposites, arguing that English criminal trial practice is fundamentally congruent with modern science's basic epistemological assumptions, values and methods of inquiry. Although practical tensions undeniably exist, they are explicable-and may be neutralised-by paying closer attention to criminal adjudication's normative ideals and their institutional expression in familiar aspects of common law trial procedure, including evidentiary rules of admissibility, trial by jury, adversarial fact-finding, cross-examination and the ethical duties of expert witnesses. Effective partnerships between lawyers and forensic scientists are indispensable for integrating scientific evidence into criminal proceedings, and must be renegotiated between individual practitioners on an on-going basis. Fruitful interdisciplinary collaboration between scholars with a shared interest in forensic science should dispense with reductive cultural stereotypes of Science and Law. Copyright © 2013.

    Ingham, J. D.; Lawson, D. D.

    1973-01-01

    In crime laboratories one of the most difficult operations is to determine unequivocally whether or not two samples of evidence of the same type were originally part of the same thing or were from the same source. It has been found that high temperature thermoluminescence (room temperature to 723 K) can be used for comparisons of this type, although work to date indicates that there is generally a finite probability for coincidental matching of glass or soil samples. Further work is required to determine and attempt to minimize these probabilities for different types of materials, and to define more clearly the scope of applicability of thermoluminescence to actual forensic situations.

    Jervis, R. E. [University of Toronto, Toronto (Canada)

    1967-10-15

    Recently the unique features of the activation analysis method have been utilized to advantage to meet some specialized needs in the scientific investigation of crime. A review of the principal forensic activation analysis applications to biological materials to date indicates that they may be roughly classified as: (i) the detection and determination of residues of toxic materials in foodstuffs, human tissues, sera and excreta; (ii) the 'individualization' of hair, fibres, narcotics and drugs; and (iii) investigation of the transference of ballistic material to bone, cloth or paper. Analyses of these materials in some actual forensic investigations have been perfected to the point of acceptance in the law courts of several countries. Additional and broader areas of application are under development in a number of nuclear and forensic laboratories. (i) The determination of sub microgram quantities of phosphorus compounds, arsenic, mercury, selenium and thallium in specimens from post-mortem examinations and from living persons showing symptoms of toxicity has revealed certain ingestion of abnormal amount of toxic substances by comparison with similar specimens from healthy persons. In some cases, with tissues such as hair and nails, the time scale of the ingestion of arsenic or mercury has been revealed through the distribution of the deposited element with distance from the growing end or edge. (ii) A series of feasibility studies on the possibility of distinguishing similar materials through their characteristic trace-element patterns have resulted from observations of the wide range or variation in trace impurity content in specimens which come from different individuals or different natural sources. For example, extensive activation analyses for more than twenty elements in human head hair from many people have been carried out and a statistical analysis of the results indicate that activation hair comparisons in forensic investigations may be quite definitive

    Full text: Traditional areas of forensic science, such as, handwriting and fingerprint examinations and the newer sciences such as molecular biology are increasingly being scrutinized and challenged by the legal and scientific communities. These older forensic disciplines are targets for critics and skeptics as they are not founded on the traditional sciences but have rather an empirical basis and are supported by what may be considered quasi-validated data. This paper discusses in broad terms the basis of these legal and scientific attitudes and the various solutions to overcoming these negative perceptions.

    Morgan, R M

    2017-11-01

    This paper builds on the FoRTE conceptual model presented in part I to address the forms of knowledge that are integral to the four components of the model. Articulating the different forms of knowledge within effective forensic reconstructions is valuable. It enables a nuanced approach to the development and use of evidence bases to underpin decision-making at every stage of a forensic reconstruction by enabling transparency in the reporting of inferences. It also enables appropriate methods to be developed to ensure quality and validity. It is recognised that the domains of practice, research, and policy/law intersect to form the nexus where forensic science is situated. Each domain has a distinctive infrastructure that influences the production and application of different forms of knowledge in forensic science. The channels that can enable the interaction between these domains, enhance the impact of research in theory and practice, increase access to research findings, and support quality are presented. The particular strengths within the different domains to deliver problem solving forensic reconstructions are thereby identified and articulated. It is argued that a conceptual understanding of forensic reconstruction that draws on the full range of both explicit and tacit forms of knowledge, and incorporates the strengths of the different domains pertinent to forensic science, offers a pathway to harness the full value of trace evidence for context sensitive, problem-solving forensic applications.

    Wiltshire, Patricia E J

    2016-11-01

    Palynology (including mycology) is widely used in palaeoecological and bioarchaeological studies. Lake and mire sediments, soils, and the deposits accumulating in archaeological features, invariably contain plant and fungal remains, particularly pollen and spores. These serve as proxy indicators of ancient environmental conditions and events. Forensic palynology has been successfully employed in criminal investigations for more than two decades. In recent years, it has included fungal palynomorphs in profiling samples from crime scenes, and from exhibits obtained from suspects and victims. This contribution outlines the main features of palynology, and gives examples of case studies where fungal spores, pollen, and plant spores, have enhanced the interpretation of ancient landscapes and land-use, and provided pivotal intelligence, and probative evidence, in criminal investigations.

  6. Practical relevance of pattern uniqueness in forensic science.

    Science.gov (United States)

    Jayaprakash, Paul T

    2013-09-10

    Uniqueness being unprovable, it has recently been argued that individualization in forensic science is irrelevant and, probability, as applied for DNA profiles, should be applied for all identifications. Critiques against uniqueness have omitted physical matching, a realistic and tangible individualization that supports uniqueness. Describing case examples illustrating pattern matches including physical matching, it is indicated that individualizations are practically relevant for forensic science as they establish facts on a definitive basis providing firm leads benefitting criminal investigation. As a tenet of forensic identification, uniqueness forms a fundamental paradigm relevant for individualization. Evidence on the indeterministic and stochastic causal pathways of characteristics in patterns available in the related fields of science sufficiently supports the proposition of uniqueness. Characteristics involved in physical matching and matching achieved in patterned evidence existing in the state of nature are not events amenable for counting; instead these are ensemble of visible units occupying the entire pattern area stretching the probability of re-occurrence of a verisimilitude pattern into infinity offering epistemic support to uniqueness. Observational methods are as respectable as instrumental or statistical methods since they are capable of generating results that are tangible and obviously valid as in physical matching. Applying the probabilistic interpretation used for DNA profiles to the other patterns would be unbefitting since these two are disparate, the causal pathways of the events, the loci, in the manipulated DNA profiles being determinable. While uniqueness enables individualizations, it does not vouch for eliminating errors. Instead of dismissing uniqueness and individualization, accepting errors as human or system failures and seeking remedial measures would benefit forensic science practice and criminal investigation.

  7. Utility of the clue - From assessing the investigative contribution of forensic science to supporting the decision to use traces.

    2015-12-01

    In an attempt to grasp the effectiveness of forensic science in the criminal justice process, a number of studies introduced some form of performance indicator. However, most of these indicators suffer from different weaknesses, from the definition of forensic science itself to problems of reliability and validity. We suggest the introduction of the concept of utility of the clue as an internal evaluation indicator of forensic science in the investigation. Utility of the clue is defined as added value of information, gained by the use of traces. This concept could be used to assess the contribution of the trace in the context of the case. By extension, a second application of this concept is suggested. By formalising and considering, a priori, the perceived utility of using traces, we introduce the notion of expected utility that could be used as decision factor when choosing which traces to use, once they have been collected at the crime scene or from an object in the laboratory. In a case-based approach, utility can be assessed in the light of the available information to evaluate the investigative contribution of forensic science. In the decision-making process, the projection or estimation of the utility of the clue is proposed to be a factor to take into account when triaging the set of traces.

    Forensic science uses the basic principles of all physical and natural science and have evolved many domain of its owns, like Anthropometry, fingerprint, Foot print, ballistics, documentation, Forensic Biology and Serology, Forensic Chemistry, Nuclear forensic science, Forensic Physic, Toxicology, Odontology, Forensic DNA, Cyber Forensic, Forensic Psychology, Forensic engineering etc., which provides a fool prove scientific aid to criminal justice administration. Nuclear forensic science is a fairly young discipline and only a small number of laboratories are active practitioners. However, the number of incidents of illicit trafficking reported and furthermore, the threat of nuclear terrorism calls for preparedness and for effective tools providing hints on the origin of the material and thus on the perpetrator. The determination of characteristic parameters is subject to ongoing research and development work in a number of nuclear measurement laboratories. Parameters like isotopic composition, chemical impurities, age of the material, macroscopic parameters and microstructure provide clues on the origin and on the intended use of the material. Today, nuclear forensics has reached a high degree of maturity and it is highly relevant in the areas of non-proliferation and of nuclear security. Continued development activities and strengthened international cooperation will be of key importance for the perfection of the discipline of nuclear forensics

    Ricci, Camilla; Kazarian, Sergei G.

    2006-09-01

    This presentation outlines the research we are developing in the area of Fourier Transform Infrared (FTIR) spectroscopic imaging with the focus on materials of forensic interest. FTIR spectroscopic imaging has recently emerged as a powerful tool for characterisation of heterogeneous materials. FTIR imaging relies on the ability of the military-developed infrared array detector to simultaneously measure spectra from thousands of different locations in a sample. Recently developed application of FTIR imaging using an ATR (Attenuated Total Reflection) mode has demonstrated the ability of this method to achieve spatial resolution beyond the diffraction limit of infrared light in air. Chemical visualisation with enhanced spatial resolution in micro-ATR mode broadens the range of materials studied with FTIR imaging with applications to pharmaceutical formulations or biological samples. Macro-ATR imaging has also been developed for chemical imaging analysis of large surface area samples and was applied to analyse the surface of human skin (e.g. finger), counterfeit tablets, textile materials (clothing), etc. This approach demonstrated the ability of this imaging method to detect trace materials attached to the surface of the skin. This may also prove as a valuable tool in detection of traces of explosives left or trapped on the surfaces of different materials. This FTIR imaging method is substantially superior to many of the other imaging methods due to inherent chemical specificity of infrared spectroscopy and fast acquisition times of this technique. Our preliminary data demonstrated that this methodology will provide the means to non-destructive detection method that could relate evidence to its source. This will be important in a wider crime prevention programme. In summary, intrinsic chemical specificity and enhanced visualising capability of FTIR spectroscopic imaging open a window of opportunities for counter-terrorism and crime-fighting, with applications ranging

    As the number of forensic science programs offered at higher education institutions rises, and more students express an interest in them, it is important to gain information regarding the offerings in terms of courses, equipment available to students, degree requirements, and other important aspects of the programs. A survey was conducted examining the existing bachelor's and master's forensic science programs in the U.S. Of the responding institutions, relatively few were, at the time of the survey, accredited by the forensic science Education Programs Accreditation Commission (FEPAC). In general, the standards of the responding programs vary considerably primarily in terms of their size and subjects coverage. While it is clear that the standards for the forensic science programs investigated are not homogeneous, the majority of the programs provide a strong science curriculum, faculties with advanced degrees, and interesting forensic-oriented courses. © 2010 American Academy of Forensic Sciences.

    Full Text Available DNA analysis in forensic science is mainly based on short tandem repeat (STR genotyping. The conventional analysis is a three-step process of DNA extraction, amplification and detection. An overview of various techniques that are currently in use and are being actively researched for STR typing is presented. The techniques are separated into STR amplification and detection. New techniques for forensic STR analysis focus on increasing sensitivity, resolution and discrimination power for suboptimal samples. These are achieved by shifting primer-binding sites, using high-fidelity and tolerant polymerases and applying novel methods to STR detection. Examples in which STRs are used in criminal investigations are provided and future research directions are discussed.

  18. Science and Society in harmony

    2009-01-01

    Yesterday I spoke at a conference hosted by an organization called Melody for Dialogue, and it struck me that this organization has much in common with a movement that contributed to CERN’s foundation 55 years ago. That movement was called ‘Atoms for Peace’. Notice the similarity? What is it that melody and atoms have in common that they can be used to promote dialogue and peace? I believe that they are both expressions of something shared by all of humanity. Whatever culture we belong to, music is a part of it. And wherever in the world we’re from, we’re all curious about our surroundings. Science and music are two of the things that make us human. The theme of the conference was environmental awareness, and I told the participants that although CERN’s research won’t bring immediate solutions to the pressing environmental problems of the world, if it were not for similar curiosity-driven research in the past, much of w...

  19. Forensic aspects of digital evidence: contributions and initiatives by the National Center for Forensic Science (NCFS)

    Science.gov (United States)

    Whitcomb, Carrie M.

    2002-07-01

    Digital evidence is information of probative value that is either stored or transmitted in a digital form. Digital evidence can exist as words (text), sound (audio), or images (video or still pictures). Law enforcement and forensic scientists are faced with collecting and analyzing these new forms of evidence that previously existed on paper or on magnetic tapes. They must apply the law and science to the processes they use. Extrapolating the old processes into the new formats has been proceeding since the 1980's. Regardless of the output format, all digital evidence has a certain commonality. One would assume that the rules of evidence and the scientific approach would also have some common characteristics. Obviously, there is also a divergence due to the differences in outputs. It is time to approach the issues regarding digital evidence in a more deliberate, organized, and scientific manner. The program outlined by the NCFS would explore these various formats, the features common to traditional types of forensic evidence, and their divergent features and explore the scientific basis for handling of digital evidence. Our web site, www.ncfs.org, describes our programs.

    Full Text Available One of the cornerstones of the judicial process is the presentation of evidence in a court of law. The integrity of evidence is vital to reassure the courts that the correct procedures were followed throughout all the processes it was subjected to. In South Africa, the Forensic Science Laboratory (FSL in Pretoria analyses and stores evidence. The storage facility within the FSL should contribute to the prevention of evidence contamination or degradation thereby also leading to improved service quality and output to its customers. The proper delivery of evidence can lead to the conviction of suspects and to the freedom of the innocent. This study investigates the storage facilities at the FSL to determine whether these are appropriate to ensure the integrity of evidence throughout all the processes it goes through and to recommend actions to continue to add value to the judicial system.

    Ogden, Rob; Linacre, Adrian

    2015-09-01

    Wildlife forensic science has become a key means of enforcing legislation surrounding the illegal trade in protected and endangered species. A relatively new dimension to this area of forensic science is to determine the geographic origin of a seized sample. This review focuses on DNA testing, which relies on assignment of an unknown sample to its genetic population of origin. Key examples of this are the trade in timber, fish and ivory and these are used only to illustrate the large number of species for which this type of testing is potentially available. The role of mitochondrial and nuclear DNA markers is discussed, alongside a comparison of neutral markers with those exhibiting signatures of selection, which potentially offer much higher levels of assignment power to address specific questions. A review of assignment tests is presented along with detailed methods for evaluating error rates and considerations for marker selection. The availability and quality of reference data are of paramount importance to support assignment applications and ensure reliability of any conclusions drawn. The genetic methods discussed have been developed initially as investigative tools but comment is made regarding their use in courts. The potential to compliment DNA markers with elemental assays for greater assignment power is considered and finally recommendations are made for the future of this type of testing.

  6. The Evolving Context for Science and Society

    Science.gov (United States)

    Leshner, Alan I.

    2012-01-01

    The relationship between science and the rest of society is critical both to the support it receives from the public and to the receptivity of the broader citizenry to science's explanations of the nature of the world and to its other outputs. Science's ultimate usefulness depends on a receptive public. For example, given that science and technology are imbedded in virtually every issue of modern life, either as a cause or a cure, it is critical that the relationship be strong and that the role of science is well appreciated by society, or the impacts of scientific advances will fall short of their great potential. Unfortunately, a variety of problems have been undermining the science-society relationship for over a decade. Some problems emerge from within the scientific enterprise - like scientific misconduct or conflicts of interest - and tarnish or weaken its image and credibility. Other problems and stresses come from outside the enterprise. The most obvious external pressure is that the world economic situation is undermining the financial support of both the conduct and infrastructure of science. Other examples of external pressures include conflicts between what science is revealing and political or economic expediency - e.g., global climate change - or instances where scientific advances encroach upon core human values or beliefs - e.g., scientific understanding of the origins and evolution of the universe as compared to biblical accounts of creation. Significant efforts - some dramatically non-traditional for many in the scientific community - are needed to restore balance to the science-society relationship.

  7. The end of the (forensic science) world as we know it? The example of trace evidence

    Roux, Claude; Talbot-Wright, Benjamin; Robertson, James; Crispino, Frank; Ribaux, Olivier

    2015-01-01

    The dominant conception of forensic science as a patchwork of disciplines primarily assisting the criminal justice system (i.e. forensics) is in crisis or at least shows a series of anomalies and serious limitations. In recent years, symptoms of the crisis have been discussed in a number of reports by various commentators, without a doubt epitomized by the 2009 report by the US National Academies of Sciences (NAS 2009 Strengthening forensic science in the United States: a path forward). Although needed, but viewed as the solution to these drawbacks, the almost generalized adoption of stricter business models in forensic science casework compounded with ever-increasing normative and compliance processes not only place additional pressures on a discipline that already appears in difficulty, but also induce more fragmentation of the different forensic science tasks, a tenet many times denounced by the same NAS report and other similar reviews. One may ask whether these issues are not simply the result of an unfit paradigm. If this is the case, the current problems faced by forensic science may indicate future significant changes for the discipline. To facilitate broader discussion this presentation focuses on trace evidence, an area that is seminal to forensic science both for epistemological and historical reasons. There is, however, little doubt that this area is currently under siege worldwide. Current and future challenges faced by trace evidence are discussed along with some possible answers. The current situation ultimately presents some significant opportunities to re-invent not only trace evidence but also forensic science. Ultimately, a distinctive, more robust and more reliable science may emerge through rethinking the forensics paradigm built on specialisms, revisiting fundamental forensic science principles and adapting them to the twenty-first century.

  8. Naturalistic decision making in forensic science: toward a better understanding of decision making by forensic team leaders.

    Helsloot, Ira; Groenendaal, Jelle

    2011-07-01

    This study uses the naturalistic decision-making (NDM) perspective to examine how Dutch forensic team leaders (i.e., the officers in charge of criminal forensic research from the crime scene until the use of laboratory assistance) make decisions in real-life settings and identifies the contextual factors that might influence those decisions. First, a focus group interview was conducted to identify four NDM mechanisms in day-to-day forensic decision making. Second, a serious game was conducted to examine the influence of three of these contextual mechanisms. The results uncovered that forensic team leaders (i) were attracted to obtain further information when more information was initially made available, (ii) were likely to devote more attention to emotionally charged cases, and (iii) used not only forensic evidence in the decision making but also tactical, unverified information of the police inquiry. Interestingly, the measured contextual influences did not deviate significantly from a control group of laypeople. © 2011 American Academy of Forensic Sciences.

    Full Text Available Statistical modeling of the evaluation of evidence with the use of the likelihood ratio has a long history. It dates from the Dreyfus case at the end of the nineteenth century through the work at Bletchley Park in the Second World War to the present day. The development received a significant boost in 1977 with a seminal work by Dennis Lindley which introduced a Bayesian hierarchical random effects model for the evaluation of evidence with an example of refractive index measurements on fragments of glass. Many models have been developed since then. The methods have now been sufficiently well-developed and have become so widespread that it is timely to try and provide a software package to assist in their implementation. With that in mind, a project (SAILR: Software for the Analysis and Implementation of Likelihood Ratios was funded by the European Network of Forensic Science Institutes through their Monopoly programme to develop a software package for use by forensic scientists world-wide that would assist in the statistical analysis and implementation of the approach based on likelihood ratios. It is the purpose of this document to provide a short review of a small part of this history. The review also provides a background, or landscape, for the development of some of the models within the SAILR package and references to SAILR as made as appropriate.

    Kodi Husimi contributed not only to research and education on physics, but also to various problems on 'Science and Society'. Especially he was involved in administration on science as a member and president of the Science Council of Japan for many years. Based upon his experience on research in nuclear physics using neutron source he opposed nuclear weapons, and pursued peace. The establishment of the three basic principles on nuclear research and development for civil uses in Japan owes to Husimi. He also made effort for international scientific collaboration, especially for support on science in developing countries. He popularized beauty and charm of science through many publications from his young age to his later years. He kept his curiosity through all his life. (author)

    2015-02-01

    In June 2013, Texas Senate Bill 344 (SB 344) was signed into law after strong Innocence Project support. SB 344 has since transformed the Texan judicial landscape. Known as the 'Junk Science Writ', SB 344 enables the court to grant habeas corpus relief based on scientific evidence that '(1) was not available to be offered by a convicted person at the convicted person's trial; or (2) contradicts scientific evidence relied on by the state at trial'. Inmates, such as the 'San Antonio Four', whose convictions were based upon what is now considered 'faulty' medical and forensic testimony, have been released under SB 344. Yet, science, as a field dependent on innovation, is inherently prone to debunking the scientific and forensic methods the law has relied upon to convict individuals. This commentary identifies policy behind SB 344, how SB 344 may influence the perception of science in the courtroom, and how 'junk science' is defined and/or limited. Furthermore, this commentary concludes that to achieve justice in the legal system through habeas relief based on 'junk science', it is necessary to revitalize and standardize forensic science.

    Since 1994 the Institute for Transuranium Elements has played the leading role in Europe in the development of Nuclear Forensic Science. This is a new discipline which has developed out of necessity following the break up of the former Soviet Union and Eastern Block countries in 1989, which resulted in the emergence of a new form of illegal smuggling - that of nuclear materials. The Institute has been involved in the investigation of all the major cases of illicit trafficking involving nuclear- and nuclear-related materials in Europe from 1994, following the first major incident at Munich airport, up to the present time. Examples will be given here illustrating different types of cases: the accidental release of nuclear material into the environment, exercises carried out in cooperation with the German Federal Police (Bundeskriminalamt), and the removal of nuclear material with deliberate criminal intent

    The forensic evaluation of trauma in occupational injuries and fatalities can provide the benefit of a more thorough analysis of incident causation. Forensic nursing science applied during workplace investigations can assist investigators to determine otherwise unknown crucial aspects of the incident circumstances that are important to event reconstruction, the enforcement of occupational health and safety requirements, and the direction of workplace prevention initiatives. Currently, a medical and forensic medical knowledge gap exists in the subject-matter expertise associated with occupational accident investigations. This gap can be bridged with the integration of forensic nursing in the investigation of workplace fatalities and serious injuries.

    Data from available literature point to an early beginning of Forensic Dentistry in Croatia relating to a post-mortem examination of a female patient after a dental procedure in the 1930s. Later on, there were several mass casualties due to collisions and airplane crashes and a railway accident at the Zagreb Main Railway Station wherein the identity of the victims was established based on dental features. Foreign experts in forensics helped identify those victims, particularly forensic dentists because this specialty was almost unknown in our region at the time. During the twenty-year period of the development of Forensic Dentistry at the University of Zagreb, the School of Dental Medicine, the city of Zagreb and Croatia have become internationally recognised on the forensic map of the world.

    2011-01-01

    Wildlife forensic science is a relatively recent development to meet the increasing need of the criminal justice system where there are investigations in alleged transgressions of either international or national legislation. This application of science draws on conservation genetics and forensic geneticists from mainstream forensic science. This review is a broad overview of the history of forensic wildlife science and some of the recent developments in forensic wildlife genetics with the application of DNA developments to nonhuman samples encountered in a forensic science investigation. The review will move from methods to look at the entire genome, when there is no previous knowledge of the species studied, through methods of species identification, using DNA to determine a possible geographic origin, through to assigning samples to a particular individual or a close genetic relative of this individual. The transfer of research methods into the criminal justice system for the investigation of wildlife crimes has been largely successful as is illustrated in the review. The review concludes with comments on the need for standardization and regulation in wildlife forensic science. Copyright © 2011 Central Police University.

  3. Epigenetic Determinism in Science and Society.

    Waggoner, Miranda R; Uller, Tobias

    2015-04-03

    The epigenetic "revolution" in science cuts across many disciplines, and it is now one of the fastest growing research areas in biology. Increasingly, claims are made that epigenetics research represents a move away from the genetic determinism that has been prominent both in biological research and in understandings of the impact of biology on society. We discuss to what extent an epigenetic framework actually supports these claims. We show that, in contrast to the received view, epigenetics research is often couched in language as deterministic as genetics research in both science and the popular press. We engage the rapidly emerging conversation about the impact of epigenetics on public discourse and scientific practice, and we contend that the notion of epigenetic determinism - or the belief that epigenetic mechanisms determine the expression of human traits and behaviors - matters for understandings of the influence of biology and society on population health.

    Next in CERN's series of Science and Society speakers is Jonathan Osborne, Senior Lecturer in Science Education at King's College London. On Thursday 26 April, Dr Osborne will speak in the CERN main auditorium about current issues in science education in the light of an ever more science-based society. Jonathan Osborne, Senior Lecturer in Science Education at King's College London. Does science deserve a place at the curriculum high table of each student or is it just a gateway to a set of limited career options in science and technology? This question leads us to an important change in our ideas of what science education has been so far and what it must be. Basic knowledge of science and technology has traditionally been considered as just a starting point for those who wanted to build up a career in scientific research. But nowadays, the processes of science, the analysis of risks and benefits, and a knowledge of the social practices of science are necessary for every citizen. This new way of looking at s...

  5. Effective use of forensic science in volume crime investigations: identifying recurring themes in the literature.

    Science.gov (United States)

    Ludwig, Anika; Fraser, Jim

    2014-01-01

    New scientific, technological and legal developments, particularly the introduction of national databases for DNA and fingerprints, have led to increased use of forensic science in the investigation of crime. There is an assumption, and in some instances specific assertions, that such developments bring improvements either in broad criminal justice terms or more narrowly in terms of economic or practical efficiencies. The underlying presumption is that the new technological opportunities will be understood and effectively implemented. This research investigates whether such increases in activity have also been accompanied by improvements in the effective use of forensic science. A systematic review of thirty-six reports published (predominantly in England and Wales) since the 1980s, which have considered the use of forensic science in the investigation of volume crimes, was carried out. These reports have identified a number of recurrent themes that influenced how effectively forensic science was used in investigations. The themes identified included forensic knowledge and training of investigators, communication and information exchange between specialists and investigators, timeliness of forensic results, interagency relationships and deployment of crime scene examiner resources. The research findings suggest that these factors continue to hinder the effective use of forensic science despite technological advances and this paper considers their potential causes. © 2013.

    Forensic strategies commonly are proceeding by analysis of short tandem repeats (STRs); however, new additional strategies have been proposed for forensic science. Thus, this article standardized the high-resolution melting (HRM) of DNA for forensic analyzes. For HRM, mitochondrial DNA (mtDNA) from eight individuals were extracted from mucosa swabs by DNAzol reagent, samples were amplified by PCR and submitted to HRM analysis to identify differences in hypervariable (HV) regions I and II. To confirm HRM, all PCR products were DNA sequencing. The data suggest that is possible discriminate DNA from different samples by HRM curves. Also, uncommon dual-dissociation was identified in a single PCR product, increasing HRM analyzes by evaluation of melting peaks. Thus, HRM is accurate and useful to screening small differences in HVI and HVII regions from mtDNA and increase the efficiency of laboratory routines based on forensic genetics. © 2017 American Academy of Forensic Sciences.

    In this paper, the importance of modern technology in forensic investigations is discussed. Recent technological developments are creating new possibilities to perform robust scientific measurements and studies outside the controlled laboratory environment. The benefits of real-time, on-site forensic investigations are manifold and such technology has the potential to strongly increase the speed and efficacy of the criminal justice system. However, such benefits are only realized when quality can be guaranteed at all times and findings can be used as forensic evidence in court. At the Netherlands Forensic Institute, innovation efforts are currently undertaken to develop integrated forensic platform solutions that allow for the forensic investigation of human biological traces, the chemical identification of illicit drugs and the study of large amounts of digital evidence. These platforms enable field investigations, yield robust and validated evidence and allow for forensic intelligence and targeted use of expert capacity at the forensic institutes. This technological revolution in forensic science could ultimately lead to a paradigm shift in which a new role of the forensic expert emerges as developer and custodian of integrated forensic platforms.

    Estimating error rates for firearm evidence identification is a fundamental challenge in forensic science. This paper describes the recently developed congruent matching cells (CMC) method for image comparisons, its application to firearm evidence identification, and its usage and initial tests for error rate estimation. The CMC method divides compared topography images into correlation cells. Four identification parameters are defined for quantifying both the topography similarity of the correlated cell pairs and the pattern congruency of the registered cell locations. A declared match requires a significant number of CMCs, i.e., cell pairs that meet all similarity and congruency requirements. Initial testing on breech face impressions of a set of 40 cartridge cases fired with consecutively manufactured pistol slides showed wide separation between the distributions of CMC numbers observed for known matching and known non-matching image pairs. Another test on 95 cartridge cases from a different set of slides manufactured by the same process also yielded widely separated distributions. The test results were used to develop two statistical models for the probability mass function of CMC correlation scores. The models were applied to develop a framework for estimating cumulative false positive and false negative error rates and individual error rates of declared matches and non-matches for this population of breech face impressions. The prospect for applying the models to large populations and realistic case work is also discussed. The CMC method can provide a statistical foundation for estimating error rates in firearm evidence identifications, thus emulating methods used for forensic identification of DNA evidence.

  11. New science, old convictions − Texas Senate Bill 344: identifying further necessary reform in forensic science

    2015-01-01

    In June 2013, Texas Senate Bill 344 (SB 344) was signed into law after strong Innocence Project support. SB 344 has since transformed the Texan judicial landscape. Known as the ‘Junk Science Writ’, SB 344 enables the court to grant habeas corpus relief based on scientific evidence that ‘(1) was not available to be offered by a convicted person at the convicted person's trial; or (2) contradicts scientific evidence relied on by the state at trial’. Inmates, such as the ‘San Antonio Four’, whose convictions were based upon what is now considered ‘faulty’ medical and forensic testimony, have been released under SB 344. Yet, science, as a field dependent on innovation, is inherently prone to debunking the scientific and forensic methods the law has relied upon to convict individuals. This commentary identifies policy behind SB 344, how SB 344 may influence the perception of science in the courtroom, and how ‘junk science’ is defined and/or limited. Furthermore, this commentary concludes that to achieve justice in the legal system through habeas relief based on ‘junk science’, it is necessary to revitalize and standardize forensic science.

    I will present some background as to the current ``scientific state'' of our society and some ideas of how we got into the fix we are in. I will then describe The Physics Force a program we developed to popularize physics. It has proven to be a very successful and entertaining outreach program of the College of Science and Engineering in the University of Minnesota developed to make science exciting and fun for students of all ages, from 6 to 106. The Force performed variations of The Physics Circus, our most popular show, at Disney's Epcot Center, parts of it were shown on Newton's Apple and several of us have performed demonstrations on the Knoff-Hoff Show, a very successful German T.V. science program. The goal of The Physics Force is to show students and the public Science is Fun, Science is Interesting, and Science is Understandable. By all measures we have available, we are extremely successful in reaching our goals. In the last three year cycle of our University support about 110,000 residents of Minnesota (or about 2% of the total population) saw a Physics Force performance; over the last decade the total is around 250,000!

    Forensic chemistry is unique among chemical sciences in that its research, practice, and presentation must meet the needs of both the scientific and the legal communities. As such, forensic chemistry research is applied and derivative by nature and design, and it emphasizes metrology (the science of measurement) and validation. Forensic chemistry has moved away from its analytical roots and is incorporating a broader spectrum of chemical sciences. Existing forensic practices are being revisited as the purview of forensic chemistry extends outward from drug analysis and toxicology into such diverse areas as combustion chemistry, materials science, and pattern evidence.

    Yeshion, Theodore Elliot

    Students' Conceptions of Science, Scientific Evidence, and Forensic Evidence during a University Introductory Forensic Science Course This study was designed to examine and understand what conceptions undergraduate students taking an introductory forensic science course had about scientific evidence. Because the relationships between the nature of science, the nature of evidence, and the nature of forensic evidence are not well understood in the science education literature, this study sought to understand how these concepts interact and affect students' understanding of scientific evidence. Four participants were purposefully selected for this study from among 89 students enrolled in two sections of an introductory forensic science course taught during the fall 2005 semester. Of the 89 students, 84 were criminal justice majors with minimal science background and five were chemistry majors with academic backgrounds in the natural and physical sciences. All 89 students completed a biographical data sheet and a pre-instruction Likert scale survey consisting of twenty questions relating to the nature of scientific evidence. An evaluation of these two documents resulted in a purposeful selection of four varied student participants, each of whom was interviewed three times throughout the semester about the nature of science, the nature of evidence, and the nature of forensic evidence. The same survey was administered to the participants again at the end of the semester-long course. This study examined students' assumptions, prior knowledge, their understanding of scientific inference, scientific theory, and methodology. Examination of the data found few differences with regard to how the criminal justice majors and the chemistry majors responded to interview questions about forensic evidence. There were qualitative differences, however, when the same participants answered interview questions relating to traditional scientific evidence. Furthermore, suggestions are

    Science Environment Technology and Society (SETS) approach helps students to connect science concept with the other aspects. This allows them to achieve a clearer depiction of how each concept is linked with the other concepts in SETS. Taking SETS into account will guide students to utilize science as a productive concept in inventing and developing technology, while minimizing its negative impacts on the environment and society. This article discusses the implementation of Sundanese local wisdoms, that can be found in the local stilt house (rumah panggung), in the Building Construction subject in vocational high school on Building Drawing Technique expertise. The stilt house structural system employs ties, pupurus joints, and wedges on its floor, wall, and truss frames, as well as its beams. This local knowledge was incorporated into the Building Construction learning program and applied on the following basic competences: applying wood’s specification and characteristics for building construction, managing wood’s specification and characteristics for building construction, analyzing building structure’s type and function based on their characteristics, reasoning building structure’s type and function based on their characteristics, categorizing wood construction works, and reasoning wood construction works. The research result is the Sundanese traditional-local-wisdom-based learning design of the Building Construction subject.

    Invalid expert witness testimony that overstated the precision and accuracy of forensic science procedures has been highlighted as a common factor in many wrongful conviction cases. This study assessed the ability of an opposing expert witness and judicial instructions to mitigate the impact of invalid forensic science testimony. Participants (N = 155) acted as mock jurors in a sexual assault trial that contained both invalid forensic testimony regarding hair comparison evidence, and countering testimony from either a defense expert witness or judicial instructions. Results showed that the defense expert witness was successful in educating jurors regarding limitations in the initial expert's conclusions, leading to a greater number of not-guilty verdicts. The judicial instructions were shown to have no impact on verdict decisions. These findings suggest that providing opposing expert witnesses may be an effective safeguard against invalid forensic testimony in criminal trials. © 2015 American Academy of Forensic Sciences.

    The search for complex, nonlinear relationships and causality in data is hindered by the availability of techniques in many domains, including forensic science. Linear multivariable techniques are useful but present some shortcomings. In the past decade, Bayesian approaches have been introduced in forensic science. To date, authors have mainly focused on providing an alternative to classical techniques for quantifying effects and dealing with uncertainty. Causal networks, including Bayesian networks, can help detangle complex relationships in data. A Bayesian network estimates the joint probability distribution of data and graphically displays dependencies between variables and the circulation of information between these variables. In this study, we illustrate the interest in utilizing Bayesian networks for dealing with complex data through an application in clinical forensic science. Evaluating the functional impairment of assault survivors is a complex task for which few determinants are known. As routinely estimated in France, the duration of this impairment can be quantified by days of 'Total Incapacity to Work' ('Incapacité totale de travail,' ITT). In this study, we used a Bayesian network approach to identify the injury type, victim category and time to evaluation as the main determinants of the 'Total Incapacity to Work' (TIW). We computed the conditional probabilities associated with the TIW node and its parents. We compared this approach with a multivariable analysis, and the results of both techniques were converging. Thus, Bayesian networks should be considered a reliable means to detangle complex relationships in data.

    This work introduces novel methods for conducting forensic analysis of file allocation traces, collectively called digital stratigraphy. These in-depth forensic analysis methods can provide insight into the origin, composition, distribution, and time frame of strata within storage media. Using case examples and empirical studies, this paper illuminates the successes, challenges, and limitations of digital stratigraphy. This study also shows how understanding file allocation methods can provide insight into concealment activities and how real-world computer usage can complicate digital stratigraphy. Furthermore, this work explains how forensic analysts have misinterpreted traces of normal file system behavior as indications of concealment activities. This work raises awareness of the value of taking the overall context into account when analyzing file system traces. This work calls for further research in this area and for forensic tools to provide necessary information for such contextual analysis, such as highlighting mass deletion, mass copying, and potential backdating. © 2017 American Academy of Forensic Sciences.

    How is jurisdiction transferred from an individual's biological body to agents of power such as the police, public prosecutors, and the judiciary, and what happens to these biological bodies when transformed from private into public objects? These questions are examined by analysing bodies situated at the intersection of science and law. More specifically, the transformation of ‘private bodies’ into ‘public bodies’ is analysed by going into the details of forensic DNA profiling in the Dutch jurisdiction. It will be argued that various ‘forensic genetic practices’ enact different forensic genetic bodies'. These enacted forensic genetic bodies are connected with various infringements of civil rights, which become articulated in exploring these forensic genetic bodies’‘normative registers’.

    Science, particularly physics, has been in a relatively privileged position since the end of World War II. Support by the government has been generous and those of us whose careers have spanned the period since World War II have, until recently, seen research funding increasing in real terms. Our support really rested on two assumptions: science would improve the lives of the citizens and science would make us secure in a world that seemed very dangerous because of the US/USSR confrontation. The world situation has changed radically, both politically and economically. The USSR is no more, and economic concerns loom much larger as our deficit has grown and as economic rivals have become much stronger. With these changes has come a re-examination of many of the assumptions about priorities for government activities. It should be no surprise that the rationale for the support of science is one of those things being re-examined. Being re-examined is not very comfortable for those under the microscope, for we are in effect being asked to rejustify our existence in terms of the relevance of our work to the problems that society perceives to be most immediate.

    Since the beginning of the 1990s, when the first seizures of nuclear material were reported, the IAEA recorded more than 800 cases of illicit trafficking of nuclear or other radioactive materials. Despite the decreasing frequency of seizures involving nuclear materials (i.e. uranium or plutonium), the issue continues to attract public attention and is a reason for concern due to the hazard associated with such materials. Once illicitly trafficked nuclear material has been intercepted, the questions of its intended use and origin are to be addressed. Especially the origin is of prime importance in order to close the gaps and improve the physical protection at the sites where the theft or diversion occurred. To answer the questions, a dedicated nuclear forensics methodology has been developed. In this paper, an overview is given on the methodologies used, the measurement techniques that are applies and on the characteristic parameters that help in the identification of the origin of the material. Some selected examples shall illustrate the challenges and the complexity associated with this work. In particular the past and on-going developments in this new area of science will be highlighted and special attention is attributed to the challenges ahead

    "Forensic podiatry is defined as the application of sound and researched podiatric knowledge and experience in forensic investigations; to show the association of an individual with a scene of crime, or to answer any other legal question concerned with the foot or footwear that requires knowledge of the functioning foot". Forensic podiatrists can contribute to forensic identification by associating the pedal evidence with the criminal or crime scene. The most common pedal evidence collected from the crime scene is in the form of footprints, shoeprints and their tracks and trails. Forensic podiatrists can establish identity of the individuals from the footprints in many ways. The analysis of bare footprints involves the identification based on the individualistic features like flat footedness, ridges, humps, creases, an extra toe, missing toe, corns, cuts, cracks, pits, deformities, and various features of the toe and heel region. All these individualistic features can link the criminal with the crime. In addition to these, parameters of body size like stature and body weight as well as sex can also be estimated by using anthropometric methods. If a series of footprints are recovered from the crime scene, then parameters of the gait analysis such as stride/step length and general movement of the criminal can be traced. Apart from these, a newly established biometric parameter of the footprints i.e. footprint ridge density can also be evaluated for personal identification. Careful analysis of the footprint ridge density can give an idea about the sex of the criminal whose footprints are recovered at the scene which can further help to reduce the burden of the investigating officer as the investigations then may be directed toward either a male suspect or a female suspect accordingly. This paper highlights various aspects of Forensic Podiatry and discusses the different methods of personal identification related to pedal evidence. Copyright © 2015 Elsevier Ireland

    Science for Society, a workshop held at the Oak Ridge National Laboratory (ORNL) on September 27, 20111, explored ways to move Laboratory science toward use. It sought actionable recommendations. Thus the workshop focused on: (1) current practices that promote and inhibit the translation of science into use, (2) principles that could lead to improving ORNL's translational knowledge and technology transfer efforts, and (3) specific recommendations for making these principles operational. This highly interactive workshop struck a positive chord with participants, a group of 26 ORNL staff members from diverse arenas of science and technology (S and T), technology transfer, and external laboratory relations, who represented all levels of science, technology, and management. Recognizing that the transformation of fundamental principles into operational practices often follows a jagged path, the workshop sought to identify key choices that could lead to a smoother journey along this path, as well as choices that created roadblocks and bottlenecks. The workshop emphasized a portion of this pathway, largely excluding the marketplace. Participants noted that research translation includes linkages between fundamental and applied research and development (R and D), and is not restricted to uptake by manufacturers, consumers, or end users. Three crosscutting ideas encapsulate workshop participants observations: (1) ORNL should take more action to usher the translation of its S and T products toward use, so as to make a positive national and global impact and to enhance its own competitiveness in the future; (2) ORNL (and external entities such as DOE and Congress) conveys inconsistent messages with regard to the importance of research translation and application, which (a) creates confusion, (b) poses disincentives to pursue research translation, (c) imposes barriers that inhibit cross-fertilization and collaboration, and (d) diminishes the effectiveness of both the

    Nuclear forensic science seeks to identify the origin of nuclear materials found outside regulatory control. It is increasingly recognized as an integral part of a robust nuclear security program. This review highlights areas of active, evolving research in nuclear forensics, with a focus on analytical techniques commonly employed in Earth and planetary sciences. Applications of nuclear forensics to uranium ore concentrates (UOCs) are discussed first. UOCs have become an attractive target for nuclear forensic researchers because of the richness in impurities compared to materials produced later in the fuel cycle. The development of chronometric methods for age dating nuclear materials is then discussed, with an emphasis on improvements in accuracy that have been gained from measurements of multiple radioisotopic systems. Finally, papers that report on casework are reviewed, to provide a window into current scientific practice.

    2007-02-01

    This meeting, held in the Limerick Institute of Technology, on Thursday 1 June 2006, was organised by the Munster Group of the Institute of Physics in Ireland to commemorate the life and work of John Desmond Bernal. Bernal, was born in Nenagh in 1901. Alan Mackay, who worked with Bernal at Birkbeck College coins the word 'Polytropic' to describe Bernal. He was active and hugely influential in a wide range of areas such as science, politics and society, and was instrumental in the creation of whole new areas of intellectual endeavour such as the 'science of science', molecular biology, and operations research. Andrew Brown's analogy for Bernal's mind is that 'it was like a diamond—beautifully structured, multifaceted and dazzling to behold'. In relation to Bernal, Helena Sheehan states that: 'His legacy is complex. All the more so because he was marxist in philosophy, communist in politics, polyamorous in sexuality.'. Like religion, these are areas that conventional scientists tend to shy away from or at the very least consign to very separate and often neglected 'compartments'. According to Sheehan, 'Bernal came to marxism seriously and intelligently. He found in its philosophical framework a structure in which he could live, think, create, pursue science, act politically and develop further. It opened him radically to the world, rather than closing him down or constricting him, as critics imply.'. And his contributions to science and to society are significant and enduring. Just two areas of 'his science' were addressed in some detail at this meeting. Martin Caffrey treats the area of structural biology in the context of modern developments but focusing on Bernal's role in its evolution. John Finney gives an account of Bernal's 'two bouts of activity' on the structure of water and as Bernal's last PhD student he gives unique insights on how Bernal worked and why he 'did science'. Bernal writes in response to a well wisher on his 70th birthday: 'I am sure that

    Tsunamis are high-impact, long-duration disasters that in most cases allow for only minutes of warning before impact. Since the 2004 Boxing Day tsunami, there have been significant advancements in warning methodology, pre-disaster preparedness and basic understanding of related phenomena. Yet, the trail of destruction of the 2011 Japan tsunami, broadcast live to a stunned world audience, underscored the difficulties of implementing advances in applied hazard mitigation. We describe state of the art methodologies, standards for warnings and summarize recent advances in basic understanding, and identify cross-disciplinary challenges. The stage is set to bridge science, engineering and society to help build up coastal resilience and reduce losses. © 2015 The Author(s).

    On Friday 8 July, the lifts in the Main Building filled with directors-general, assistant directors-general, chiefs of staff, and secretaries-general from a veritable alphabet soup of international organisations. They were heading to a round-table discussion about science and society, chaired by CERN Director-General, Rolf Heuer. “We need to get away from talking like the dense books we read, and start speaking in ‘normal’ language,” said one of the delegates during the round table. The 19 high-ranking delegates from UNESCO, DOE, WHO, WMO, and OECD – to name but a few – sat over coffee and a working lunch, sharing ideas and opinions in a deliberately informal setting. Are the benefits of science being appropriately communicated to decision makers? How will basic research cope during these tough economic times? How can the applications of scientific research be more firmly linked to basic scientific research? Delegates jumped from topic to topic: fr...

    The aim of this study was to understand factors that influence post-traumatic stress (PTS) in Korean forensic science investigators. A total of 111 forensic science investigators were recruited in Korea. PTS was measured using the tool modified by Choi (2001) from the original developed by Foa, Riggs, Dancu, and Rothbaum (1993) based on DSM-IV. Factors influencing PTS included demographic and job-related characteristics, emotional intelligence, and death anxiety. PTS scores were positively correlated with personality type, fatigue from work, and death anxiety. PTS scores were negatively correlated with length of career as a forensic science investigator and emotional intelligence. The factors that had the greatest influence on PTS were death anxiety, years spent as a forensic science investigator, personality type, emotional intelligence, fatigue, and homicide experience. The explanatory power of these six factors was 44.0%. Therefore, it is necessary to regularly evaluate the mental health of those who are vulnerable to PTS. Based on these results, various interventions could be implemented for promoting overall health of the forensic science investigators. Copyright © 2013. Published by Elsevier B.V.

    The critical care nurse is in an ideal position to assume responsibilities related to the identification of forensic cases and the preservation of associated evidence. Victims of child and elder abuse and neglect, individuals involved in vehicular or industrial accidents, substance abusers, and incarcerated populations are among the several types of patients that are likely to managed in the intensive care unit (ICU). Hospitals and their personnel assume considerable liability in such cases for detecting, collecting, and preserving evidence, as well as for reporting and referring the cases to appropriate law enforcement or judicial authorities. The Joint Commission for the Accreditation of Healthcare Organizations has published specific regulatory guidance to ensure that all healthcare personnel are properly educated to assume certain forensic responsibilities. The orientation and in-service programs of the ICU nurse should include specific guidance regarding forensic principles, practices, and procedures.

    The issue that has been analyzed in this work is the potential effect of crime films and TV series on people's perceptions of forensic medicine and science, and especially on the forming of expectations towards forensic science experts. This syndrome is being called the "CSI effect" after the popular franchise Crime Scene Investigation (CSI). Questionnaire surveys that have been conducted included "experts": 50 experts in various specialities, 77 prosecutors, 119 judges, 64 lay judges, 161 police staff and 80 members of general public. In-depth interviews have been conducted with 20 police staff, and also a focus group has been carried out with 15 law students. In the opinion of the respondents, people's perceptions and expectations of forensic science--as it can be observed during criminal trials--are largely inflated by the entertainment media. Among the surveyed persons, the category that declares watching crime series most rarely, is forensic science experts. Around half of the surveyed experts pointed out to excessive expectations towards they work instigated by TV crime series. The most common expectations towards forensic medicine experts are: immediate conclusiveness of post mortem examinations (going as far as indicating the cause of death at the crime scene), precision of death time estimation and a routine use of sophisticated methods known from TV.

  20. Forensic Science Research and Development at the National Institute of Justice: Opportunities in Applied Physics

    Science.gov (United States)

    Dutton, Gregory

    Forensic science is a collection of applied disciplines that draws from all branches of science. A key question in forensic analysis is: to what degree do a piece of evidence and a known reference sample share characteristics? Quantification of similarity, estimation of uncertainty, and determination of relevant population statistics are of current concern. A 2016 PCAST report questioned the foundational validity and the validity in practice of several forensic disciplines, including latent fingerprints, firearms comparisons and DNA mixture interpretation. One recommendation was the advancement of objective, automated comparison methods based on image analysis and machine learning. These concerns parallel the National Institute of Justice's ongoing R&D investments in applied chemistry, biology and physics. NIJ maintains a funding program spanning fundamental research with potential for forensic application to the validation of novel instruments and methods. Since 2009, NIJ has funded over 179M in external research to support the advancement of accuracy, validity and efficiency in the forensic sciences. An overview of NIJ's programs will be presented, with examples of relevant projects from fluid dynamics, 3D imaging, acoustics, and materials science.

  1. Weakening forensic science in Spain: from expert evidence to documentary evidence.

    2012-07-01

    An amendment in 2002 to the Spanish Code of Criminal Procedure converted into documentary evidence the expert reports prepared by official laboratories aimed at determining the nature, weight, and purity of seized drugs. In most cases, experts are spared from appearance before the courts. This is likely to be extended to other forensic fields. After an overview of criminalistic identification in current forensic science, the objectivity and reliability concepts used by jurists and scientists are considered by comparing the paradigm of individualization with that of likelihood. Subsequently, a detailed critical study is made on the above-mentioned Spanish legal reform, and a comparison is made with the decision on the Melendez-Diaz v. Massachusetts case as ruled by the Supreme Court of the United States. Although the reform is in compliance with the Spanish Constitution, it is at odds with science, in particular regarding the logic underpinning the scientific evaluation of evidence. © 2012 American Academy of Forensic Sciences.

    This study investigated the current status of infection management for forensic science investigators in South Korea. This study included 104 forensic science investigators, of which 97.1% were exposed to the blood or body fluids of corpses during handling. Of these investigators, 98% claimed they wore gloves, and 12.9% used double-layered gloves. A total of 70.6% of the participants with relevant work experience wore masks to reduce infection risk; 43% wore gowns and goggles when at risk of contracting an infection. Furthermore, 59.8% of the investigators with pertinent work experience sought appropriate first aid and treatment when they experienced contaminated skin cuts or stab wounds. Working conditions and other problems should be analyzed consistently with the cooperation of employees, occupational health practitioners, and relevant organizations to prevent work-associated infections among forensic science investigators. © 2015 The Author(s).

    The use of biostatistical software programs to assist in data interpretation and calculate likelihood ratios is essential to forensic geneticists and part of the daily case work flow for both kinship and DNA identification laboratories. Previous recommendations issued by the DNA Commission of the International Society for Forensic Genetics (ISFG) covered the application of bio-statistical evaluations for STR typing results in identification and kinship cases, and this is now being expanded to provide best practices regarding validation and verification of the software required for these calculations. With larger multiplexes, more complex mixtures, and increasing requests for extended family testing, laboratories are relying more than ever on specific software solutions and sufficient validation, training and extensive documentation are of upmost importance. Here, we present recommendations for the minimum requirements to validate bio-statistical software to be used in forensic genetics. We distinguish between developmental validation and the responsibilities of the software developer or provider, and the internal validation studies to be performed by the end user. Recommendations for the software provider address, for example, the documentation of the underlying models used by the software, validation data expectations, version control, implementation and training support, as well as continuity and user notifications. For the internal validations the recommendations include: creating a validation plan, requirements for the range of samples to be tested, Standard Operating Procedure development, and internal laboratory training and education. To ensure that all laboratories have access to a wide range of samples for validation and training purposes the ISFG DNA commission encourages collaborative studies and public repositories of STR typing results.

  4. The Role of the Subjectivist Position in the Probabilization of Forensic Science

    Directory of Open Access Journals (Sweden)

    Alex Biedermann

    2015-01-01

    Full Text Available This paper is concerned with the contribution of forensic science to the legal process by helping reduce uncertainty. Although it is now widely accepted that uncertainty should be handled by probability because it is a safeguard against incoherent proceedings, there remain diverging and conflicting views on how probability ought to be interpreted. This is exemplified by the proposals in scientific literature that call for procedures of probability computation that are referred to as "objective," suggesting that scientists ought to use them in their reporting to recipients of expert information. I find such proposals objectionable. They need to be viewed cautiously, essentially because ensuing probabilistic statements can be perceived as making forensic science prescriptive. A motivating example from the context of forensic DNA analysis will be chosen to illustrate this. As a main point, it shall be argued that such constraining suggestions can be avoided by interpreting probability as a measure of personal belief, that is, subjective probability. Invoking references to foundational literature from mathematical statistics and philosophy of science, the discussion will explore the consequences of this interdisciplinary viewpoint for the practice of forensic expert reporting. It will be emphasized that–as an operational interpretation of probability–the subjectivist perspective enables forensic science to add value to the legal process, in particular by avoiding inferential impasses to which other interpretations of probability may lead. Moreover, understanding probability from a subjective perspective can encourage participants in the legal process to take on more responsibility in matters regarding the coherent handling of uncertainty. This would assure more balanced interactions at the interface between science and the law. This, in turn, provides support for ongoing developments that can be called the "probabilization" of forensic science.

    Full Text Available Virtual Globes reached the mass market in 2005. They created multi-million dollar businesses in a very short time by providing novel ways to explore data geographically. We use the term “Virtual Globes” as the common denominator for technologies offering capabilities to annotate, edit and publish geographic information to a world-wide audience and to visualize information provided by the public and private sectors, as well as by citizens who volunteer new data. Unfortunately, but not surprising for a new trend or paradigm, overlapping terms such as “Virtual Globes”, “Digital Earth”, “Geospatial Web”, “Geoportal” or software specific terms are used heterogeneously. We analyze the terminologies and trends in scientific publications and ask whether these developments serve science and society. While usage can be answered quantitatively, the authors reason from the literature studied that these developments serve to educate the masses and may help to democratize geographic information by extending the producer base. We believe that we can contribute to a better distinction between software centered terms and the generic concept as such. The power of the visual, coupled with the potential of spatial analysis and modeling for public and private purposes raises new issues of reliability, standards, privacy and best practice. This is increasingly addressed in scientific literature but the required body of knowledge is still in its infancy.

    In forensic sciences, bone marrow (BM) is an alternative matrix in postmortem toxicology because of its good resistance to autolysis and contaminations. Nevertheless, few studies have been focused on postmortem BM morphological changes after pathological stimuli. We examined 73 BM samples from forensic autopsies; causes of death were both natural and traumatic. BM samples were collected from the sternum by needle aspiration and biopsy; in selected cases, immunohistochemistry was performed. Few autolytic changes were found; BM cellularity decreased with increasing age and postmortem interval. Notable cell changes were detected in 45 cases (61.64%): neoplastic (n=4), and non-neoplastic BM findings (n=41), including multiorgan failure/sepsis (n=26), myelodisplastic-like conditions (n=11), and anaphylactic reactions (n=4). The results showed that BM cellularity supported circumstantial and autopsy findings, suggesting that BM samples could be a useful tool in forensic science applications.

    As an important part of epigenetic marker, DNA methylation involves in the gene regulation and attracts a wide spread attention in biological auxology, geratology and oncology fields. In forensic science, because of the relative stable, heritable, abundant, and age-related characteristics, DNA methylation is considered to be a useful complement to the classic genetic markers for age-prediction, tissue-identification, and monozygotic twins' discrimination. Various methods for DNA methylation detection have been validated based on methylation sensitive restriction endonuclease, bisulfite modification and methylation-CpG binding protein. In recent years, it is reported that the third generation sequencing method can be used to detect DNA methylation. This paper aims to make a review on the detection method of DNA methylation and its applications in forensic science. Copyright© by the Editorial Department of Journal of Forensic Medicine.

  9. Statistical hypothesis testing and common misinterpretations: Should we abandon p-value in forensic science applications?

    Science.gov (United States)

    Taroni, F; Biedermann, A; Bozza, S

    2016-02-01

    Many people regard the concept of hypothesis testing as fundamental to inferential statistics. Various schools of thought, in particular frequentist and Bayesian, have promoted radically different solutions for taking a decision about the plausibility of competing hypotheses. Comprehensive philosophical comparisons about their advantages and drawbacks are widely available and continue to span over large debates in the literature. More recently, controversial discussion was initiated by an editorial decision of a scientific journal [1] to refuse any paper submitted for publication containing null hypothesis testing procedures. Since the large majority of papers published in forensic journals propose the evaluation of statistical evidence based on the so called p-values, it is of interest to expose the discussion of this journal's decision within the forensic science community. This paper aims to provide forensic science researchers with a primer on the main concepts and their implications for making informed methodological choices. Copyright © 2015 Elsevier Ireland Ltd.

    Vaginal discharge and bleeding in children require a through and thoughtful evaluation to diagnose the underlying problem including infections, sexual abuse, and vaginal foreign bodies. We report a 6-year-old girl presenting with bloody vaginal discharge, carefully evaluated for sexual abuse, and finally diagnosed as a vaginal foreign body after vaginoscopy. A rolling hair ball was extracted from the vagina and was diagnosed as trichobezoar pathologically without any endo-ecto-mesodermal residual tissue. The hair ball was genetically detected and diagnosed to belong herself by containing no foreign structure. Child sexual abuse was ruled out by forensic interview at CAC and report of forensic science that reported genetic structure belonging to the child. Medicolegal assessment helped in final diagnosis to exclude child sexual abuse. © 2016 American Academy of Forensic Sciences.

    The Soil Science Society of Nigeria (SSSN) founded in 1968, is a registered member of the African Soil Science Association, International Union of Soil Science and the Global Soil Partnership. The Society aims at promoting and fostering better understanding of basic and applied Soil Science in Nigeria. The society also strives to enhance the dissemination of knowledge in all aspects of Soil science and shares ideas with National and International Societies through conferences, symposium, lectures, seminars and journal publications. The numerical strength of the society is 600 members (student, ordinary ,life and corporate). The soil science society of Nigeria has provided invaluable services in the formulation of agricultural land and fertilizer use strategies and policies of the country. The existing reconnaissance soil map of Nigeria typifies one of the major professional services rendered to the country by the society and its members. Despite the numerous contributions the society has made to the advancement of soil science in the country, the larger society is not aware of the its existence. This is largely because of our limited soil extension activities to land users due to lack of funds. If the society can attract donor funds, this will go a long way in enhancing the capacity and capability of the society.

    The forensic community utilises a myriad of techniques to investigate a wide range of materials, from paint flakes to DNA. The various microscopic techniques have provided some of the greatest contributions, e.g., FT-IR (Fourier-transform infrared) microspectroscopy utilised in copy toner discrimination, multi-layer automobile paint fragment examination, etc, SEM-EDA (scanning electron microscopy with energy dispersive analysis) used to investigate glass fragments, fibers, and explosives, and SEM in microsampling for elemental analysis, just to name a few. This study demonstrates the ability of the Scanning Probe Microscope (SPM) to analyse human fingerprints on surfaces utilising a step-and-scan feature, enabling analysis of a larger field-of-view. We also extend a line crossings study by incorporating height analysis and surface roughness measurements. The study demonstrates the potential for SPM techniques to be utilised for forensic analysis which could complement the more traditional methodologies used in such investigations.

    The events of 11th September 2001 have reminded us of the importance of taking preventive action in the field of nuclear terrorism as well as measures to mitigate the effects after such an attack. We have seen in the last 10 years the emergence of a new and potentially hazardous form of smuggling: that of nuclear and radioactive materials. The threat of terrorist activities involving nuclear materials has now become a matter of concern as well. Dispersion of such materials over urban areas, their introduction in the food chain or drinking water system are examples of currently perceived risks to our modern societies. Following its early involvement in a large number of cases of illicit trafficking and environmental issues the Institute for Transuranium Elements has developed a new discipline to support Member State authorities to combat illicit trafficking and dealing with criminal environmental issues: nuclear forensic science. The principal aims of research in this field at ITU are: (1) To maintain and develop further investigative techniques for identifying the nature of seized materials, to assess the immediate danger, to locate the original source of the material and, as far as possible, the route it has taken, and to give an opinion on the probable intended use of the material; (2) To foster close contacts with law enforcement agencies -- Europol, Interpol, World Customs Organisation and national police forces -- and to develop techniques to optimise collaboration between standard forensic techniques and the special requirements of the nuclear scientist; (3) To develop and implement a programme of assistance for applicant countries in combating illicit trafficking within their own borders. This involves giving advice, training operators and officials in the detection of illicit materials and the supply of appropriate equipment, such as radiation detectors; (4) To maintain and update an extensive database on commercial nuclear materials -- a separate section

    2018-02-12

    This article delineates 2 separate but related subfields of psychological science and practice applicable across all major areas of the field (e.g., clinical, counseling, developmental, social, cognitive, community). Forensic and correctional psychology are related by their historical roots, involvement in the justice system, and the shared population of people they study and serve. The practical and ethical contexts of these subfields is distinct from other areas of psychology-and from one another-with important implications for ecologically valid research and ethically sound practice. Forensic psychology is a subfield of psychology in which basic and applied psychological science or scientifically oriented professional practice is applied to the law to help resolve legal, contractual, or administrative matters. Correctional psychology is a subfield of psychology in which basic and applied psychological science or scientifically oriented professional practice is applied to the justice system to inform the classification, treatment, and management of offenders to reduce risk and improve public safety. There has been and continues to be great interest in both subfields-especially the potential for forensic and correctional psychological science to help resolve practical issues and questions in legal and justice settings. This article traces the shared and separate developmental histories of these subfields, outlines their important distinctions and implications, and provides a common understanding and shared language for psychologists interested in applying their knowledge in forensic or correctional contexts.

  18. Stable isotope ratio mass spectrometry in forensic science and food adulteration research

    International Nuclear Information System (INIS)

    Kumar, B.

    2009-01-01

    Stable Isotope Ratio Mass Spectrometry (SIRMS) is an established technique for the determination of origin of geological, biological, chemical and physio-chemical samples/materials. With the development of highly precise mass spectrometers, the stable isotope ratio determination of hydrogen, carbon, nitrogen and oxygen have gained considerable interest in the fields of forensic science and food authentication. Natural variations in the isotopic composition of lighter elements occur due to fractionation effects, resulting in the finger printing of specific isotope ratio values that are characteristic of the origin, purity, and manufacturing processes of the products and their constituents. Forensic science uses scientific and technical methods to investigate traceable evidence of criminal acts. Stable isotope ratio mass spectrometry has been applied to numerous aspects of the forensic science. The analysis of explosives such as ammonium nitrate, gun powder and tri-nitro-toluene (TNT), cases of murder, armed robbery, drug smuggling, terrorism, arson and hit and run traffic accidents are a few of them. The main types of geological evidences in such cases are mud, soil, rocks, sand, gravel, dust particles, biological materials, organic particles and anthropogenic components. Stable isotopes are used as tools to corroborate and confirm the evidential leads in the investigation of such crimes. The variation in natural abundances of carbon and nitrogen and their isotopic ratios δ 13 C and δ 15 N can identify links between items found at crime scene with those of suspect. The paper discusses the applications of SIRMS in the field of forensic science and food adulteration research

    2016-03-01

    In the field of forensic science, conventional infrared spectral analysis technique is usually unable to meet the detection requirements, because only very a few trace material evidence with diverse shapes and complex compositions, can be extracted from the crime scene. Infrared microscopic technique is developed based on a combination of Fourier-transform infrared spectroscopic technique and microscopic technique. Infrared microscopic technique has a lot of advantages over conventional infrared spectroscopic technique, such as high detection sensitivity, micro-area analysisand nondestructive examination. It has effectively solved the problem of authentication of trace material evidence in the field of forensic science. Additionally, almost no external interference is introduced during measurements by infrared microscopic technique. It can satisfy the special need that the trace material evidence must be reserved for witness in court. It is illustrated in detail through real case analysis in this experimental center that, infrared microscopic technique has advantages in authentication of trace material evidence in forensic science field. In this paper, the vibration features in infrared spectra of material evidences, including paints, plastics, rubbers, fibers, drugs and toxicants, can be comparatively analyzed by means of infrared microscopic technique, in an attempt to provide powerful spectroscopic evidence for qualitative diagnosis of various criminal and traffic accident cases. The experimental results clearly suggest that infrared microscopic technique has an incomparable advantage and it has become an effective method for authentication of trace material evidence in the field of forensic science.

  5. Animal Models in Forensic Science Research: Justified Use or Ethical Exploitation?

    Science.gov (United States)

    Mole, Calvin Gerald; Heyns, Marise

    2018-05-01

    A moral dilemma exists in biomedical research relating to the use of animal or human tissue when conducting scientific research. In human ethics, researchers need to justify why the use of humans is necessary should suitable models exist. Conversely, in animal ethics, a researcher must justify why research cannot be carried out on suitable alternatives. In the case of medical procedures or therapeutics testing, the use of animal models is often justified. However, in forensic research, the justification may be less evident, particularly when research involves the infliction of trauma on living animals. To determine how the forensic science community is dealing with this dilemma, a review of literature within major forensic science journals was conducted. The frequency and trends of the use of animals in forensic science research was investigated for the period 1 January 2012-31 December 2016. The review revealed 204 original articles utilizing 5050 animals in various forms as analogues for human tissue. The most common specimens utilized were various species of rats (35.3%), pigs (29.3%), mice (17.7%), and rabbits (8.2%) although different specimens were favored in different study themes. The majority of studies (58%) were conducted on post-mortem specimens. It is, however, evident that more needs to be done to uphold the basic ethical principles of reduction, refinement and replacement in the use of animals for research purposes.

    An evaluation of the Integrated Practice Model for Forensic Nursing Science () is presented utilizing methods outlined by . A brief review of nursing theory basics and evaluation methods by Meleis is provided to enhance understanding of the ensuing theoretical evaluation and critique. The Integrated Practice Model for Forensic Nursing Science, created by forensic nursing pioneer Virginia Lynch, captures the theories, assumptions, concepts, and propositions inherent in forensic nursing practice and science. The historical background of the theory is explored as Lynch's model launched the role development of forensic nursing practice as both a nursing and forensic science specialty. It is derived from a combination of nursing, sociological, and philosophical theories to reflect the grounding of forensic nursing in the nursing, legal, psychological, and scientific communities. As Lynch's model is the first inception of forensic nursing theory, it is representative of a conceptual framework although the title implies a practice theory. The clarity and consistency displayed in the theory's structural components of assumptions, concepts, and propositions are analyzed. The model is described and evaluated. A summary of the strengths and limitations of the model is compiled followed by application to practice, education, and research with suggestions for ongoing theory development.

  8. On the use of IRMS in forensic science: proposals for a methodological approach.

    Science.gov (United States)

    Gentile, Natacha; Besson, Luc; Pazos, Diego; Delémont, Olivier; Esseiva, Pierre

    2011-10-10

    The flourishing number of publications on the use of isotope ratio mass spectrometry (IRMS) in forensic science denotes the enthusiasm and the attraction generated by this technology. IRMS has demonstrated its potential to distinguish chemically identical compounds coming from different sources. Despite the numerous applications of IRMS to a wide range of forensic materials, its implementation in a forensic framework is less straightforward than it appears. In addition, each laboratory has developed its own strategy of analysis on calibration, sequence design, standards utilisation and data treatment without a clear consensus. Through the experience acquired from research undertaken in different forensic fields, we propose a methodological framework of the whole process using IRMS methods. We emphasize the importance of considering isotopic results as part of a whole approach, when applying this technology to a particular forensic issue. The process is divided into six different steps, which should be considered for a thoughtful and relevant application. The dissection of this process into fundamental steps, further detailed, enables a better understanding of the essential, though not exhaustive, factors that have to be considered in order to obtain results of quality and sufficiently robust to proceed to retrospective analyses or interlaboratory comparisons.

  9. Science and society: a dialogue without communicators?

    Directory of Open Access Journals (Sweden)

    2008-03-01

    Full Text Available To give a good public speech is art; but definitely more difficult is to organize a productive exchange of points of views between scientists, experts, non-experts and policy-makers on controversial issues such as a scenario workshop or a consensus conference. Many skills and a deep knowledge both of the topic and of the methodology are required. But this is the future of science communication, a field where the dialogical model will impose new and complex formats of communication and a new sensibility, using also the most traditional media. But are science communicators prepared for that? What is the state of the art of science communicator training?

    The aim of this essay is to understand the relationship between knowledge and society and to reflect on the links between science and political decision making. The text evolved from a number of reflections the author made while president of the European Astronomical Society, president of the Swiss Academy of Sciences and vice-president of the European Academies Science Advisory Council (EASAC). The book starts by using astronomy as a showcase for what science brings to society in terms of intellectual enrichment, of practical tools and of societal inputs. It then turns to looking generally at science as a human endeavour for which pleasure is a prime motivation and it describes the efforts made by researchers to rationalise their findings, thus making them universally acceptable. The author also describes the role of science in shaping our environment and discusses resulting responsibility of the scientists with respect to the evolution of the world.

    Science.gov (United States)

    Lockhart, Joseph J; Satya-Murti, Saty

    2017-11-01

    Cognitive effort is an essential part of both forensic and clinical decision-making. Errors occur in both fields because the cognitive process is complex and prone to bias. We performed a selective review of full-text English language literature on cognitive bias leading to diagnostic and forensic errors. Earlier work (1970-2000) concentrated on classifying and raising bias awareness. Recently (2000-2016), the emphasis has shifted toward strategies for "debiasing." While the forensic sciences have focused on the control of misleading contextual cues, clinical debiasing efforts have relied on checklists and hypothetical scenarios. No single generally applicable and effective bias reduction strategy has emerged so far. Generalized attempts at bias elimination have not been particularly successful. It is time to shift focus to the study of errors within specific domains, and how to best communicate uncertainty in order to improve decision making on the part of both the expert and the trier-of-fact. © 2017 American Academy of Forensic Sciences.

    Growing energy demand, global climate disruption and the prospect of a carbon-constrained world have opened the door for discussion of a potential nuclear renaissance. The fact that deployment of nuclear energy has not been fully embraced points to a number of challenges. These range from concerns about safety, security and proliferation of nuclear materials to questions of feasibiity and economics. Others cite the continuing quest for an acceptable approach to the management of long-lived wastes and uncertainty about risks to human health and the environment. Arguably public acceptance of nuclear energy will require policy makers to examine many social and ethical concerns, both real and perceived. Yet research suggests that public trust in governments and institutions is eroding while society's expectations to be involved in decision-making have become more intense and sophisticated. The recent Canadian experience of selecting an approach for the long-term management of used nuclear fuel illustrates the complexity of obtaining a ``social licence'' to proceed. A key objective was to gather and document the terms and conditions that would make such a project acceptable to society and to reflect a fundamental understanding and respect for these factors in the project's actual design and implementation. The underlying philosophy was that the analysis of scientific and technical evidence, while essential, could not be the sole determining factor. Ultimately it is society that will determine which risks it is prepared to accept. The mission of developing collaboratively with Canadians a management approach that would be socially acceptable, technically sound, environmentally responsible and economically feasible required the development of an integrated, systemic analytical framework and an interactive and transparent process of dialogue and deliberation. This investment in seeking diversity of perspectives resulted in the mergence of common ground among citizens and

    High-energy, ionizing radiation is called ionizing because it can knock electrons out of atoms and molecules, creating electrically charged particles called ions. Material that ionizing radiation passes through absorbs energy from the radiation mainly through this process of ionization. Ionizing radiation can be used for many beneficial purposes, but it also can cause serious, negative health effects. That is why it is one of the most thoroughly studied subjects in modern science. Most of our attention in this publication is focused on ionizing radiation -- what it is, where it comes from, and some of its properties

    Several modern techniques have been applied to prevent counterfeiting of money bills. The objective of this study was to demonstrate the potential of Portable X-ray Fluorescence (PXRF) technique and the multivariate analysis method of Principal Component Analysis (PCA) for classification of bills in order to use it in forensic science. Bills of Dollar, Euro and Real (Brazilian currency) were measured directly at different colored regions, without any previous preparation. Spectra interpretation allowed the identification of Ca, Ti, Fe, Cu, Sr, Y, Zr and Pb. PCA analysis separated the bills in three groups and subgroups among Brazilian currency. In conclusion, the samples were classified according to its origin identifying the elements responsible for differentiation and basic pigment composition. PXRF allied to multivariate discriminate methods is a promising technique for rapid and no destructive identification of false bills in forensic science. Copyright © 2013 Elsevier Ltd.

    This review discusses the methodology of nuclear forensics and illicit trafficking of nuclear materials. Nuclear forensics is relatively new scientific branch whose aim it is to read out material inherent from nuclear material. Nuclear forensics investigations have to be considered as part of a comprehensive set of measures for detection,interception, categorization and characterization of illicitly trafficking nuclear material. Prevention, detection and response are the main elements in combating illicit trafficking. Forensics is a key element in the response process. Forensic science is defined as the application of a broad spectrum of sciences to answer questions of interest to the legal system. Besides, in this study we will explain age determination of nuclear materials.

    2015-06-01

    Isotope ratio mass spectrometry (IRMS) has been used in numerous fields of forensic science in a source inference perspective. This review compiles the studies published on the application of isotope ratio mass spectrometry (IRMS) to the traditional fields of forensic science so far. It completes the review of Benson et al. [1] and synthesises the extent of knowledge already gathered in the following fields: illicit drugs, flammable liquids, human provenancing, microtraces, explosives and other specific materials (packaging tapes, safety matches, plastics, etc.). For each field, a discussion assesses the state of science and highlights the relevance of the information in a forensic context. Through the different discussions which mark out the review, the potential and limitations of IRMS, as well as the needs and challenges of future studies are emphasized. The paper elicits the various dimensions of the source which can be obtained from the isotope information and demonstrates the transversal nature of IRMS as a tool for source inference.

  14. The utilization of forensic science and criminal profiling for capturing serial killers.

    Science.gov (United States)

    White, John H; Lester, David; Gentile, Matthew; Rosenbleeth, Juliana

    2011-06-15

    Movies and nightly television shows appear to emphasize highly efficient regimens in forensic science and criminal investigative analysis (profiling) that result in capturing serial killers and other perpetrators of homicide. Although some of the shows are apocryphal and unrealistic, they reflect major advancements that have been made in the fields of forensic science and criminal psychology during the past two decades that have helped police capture serial killers. Some of the advancements are outlined in this paper. In a study of 200 serial killers, we examined the variables that led to police focusing their attention on specific suspects. We developed 12 categories that describe how serial killers come to the attention of the police. The results of the present study indicate that most serial killers are captured as a result of citizens and surviving victims contributing information that resulted in police investigations that led to an arrest. The role of forensic science appears to be important in convicting the perpetrator, but not necessarily in identifying the perpetrator. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    The PIXE technique has been successfully applied to study crime related problems in forensic science. The experimental arrangements and various practical problems involved are discussed. Consistency and reproducibility checks are presented. The results from the gun-shot residue profiles of the associated elements about the bullet hole obtained for various firing distances showed that the sensitivity of the PIXE technique could play a vital role in forensic science in assigning the distance from the gun to the victim and identifying the type of bullet used. PIXE runs on other forensic related specimens demonstrate its usefulness in indetification and evaluation of vital parameters related to a crime. The reliability and the importance of the PIXE method in solving criminal and related problems in forensic science are discussed. (orig.)

  18. Support Science by Publishing in Scientific Society Journals.

    Science.gov (United States)

    Schloss, Patrick D; Johnston, Mark; Casadevall, Arturo

    2017-09-26

    Scientific societies provide numerous services to the scientific enterprise, including convening meetings, publishing journals, developing scientific programs, advocating for science, promoting education, providing cohesion and direction for the discipline, and more. For most scientific societies, publishing provides revenues that support these important activities. In recent decades, the proportion of papers on microbiology published in scientific society journals has declined. This is largely due to two competing pressures: authors' drive to publish in "glam journals"-those with high journal impact factors-and the availability of "mega journals," which offer speedy publication of articles regardless of their potential impact. The decline in submissions to scientific society journals and the lack of enthusiasm on the part of many scientists to publish in them should be matters of serious concern to all scientists because they impact the service that scientific societies can provide to their members and to science.

  2. Mitochondrial DNA in wildlife forensic science: Species identification of tissues

    Science.gov (United States)

    Cronin, Matthew A.; Palmisciano, Daniel A.; Vyse, Ernest R.; Cameron, David G.

    1991-01-01

    A common problem in wildlife law enforcement is identifying the species of origin of carcasses, meat, or blood when morphological characters such as hair or bones are not available. Immunological and protein electrophoretic (allozyme or general protein) procedures have been used in species identification with considerable success (Bunch et al. 1976, McClymont et al. 1982, Wolfe 1983, Mardini 1984, Pex and Wolfe 1985, Dratch 1986), However, immunological tests often are not sensitive enough to distinguish closely related species. Furthermore, electrophoretically detectable protein polymorphisms may be lacking in certain populations or species and may not be species-specific.Analysis of DNA in human and wildlife forensics has been shown to be a potentially powerful tool for identification of individuals (Jeffreys et al. 1985, Vassartet al. 1987, Thommasen et al. 1989). Differences in copy number and nucleotide sequence of repetitive sequences in the nuclear (chromosomal) DNA result in hypervariability and individual-specific patterns which have been termed DNA "fingerprints." However, these patterns may be too variable for species identification necessitating analyses of more conservative parts of the genome.Mitochondrial DNA (mtDNA) is haploid, maternally inherited, similar in nucleotide sequence among conspecifics from the same geographic region, and more suitable for species identification, in contrast to hypervariable DNA fingerprints. MtDNA has several characteristics which make it useful as a species-specific marker. In mammals, individuals have a single mtDNA genotype shared by all tissues. Because mtDNA is haploid and reflects only maternal ancestry, the mtDNA gene number in a population is 4 times less than the nuclear gene number (Birky et al. 1983). This can result in relatively rapid loss or fixation of mtDNA genotypes so that all individuals in a population may be descended from a single ancestral female in as few as 4N (N = population size) generations

  4. Application of chemical structure and bonding of actinide oxide materials for forensic science

    International Nuclear Information System (INIS)

    Wilkerson, Marianne Perry

    2010-01-01

    We are interested in applying our understanding of actinide chemical structure and bonding to broaden the suite of analytical tools available for nuclear forensic analyses. Uranium- and plutonium-oxide systems form under a variety of conditions, and these chemical species exhibit some of the most complex behavior of metal oxide systems known. No less intriguing is the ability of AnO 2 (An: U, Pu) to form non-stoichiometric species described as AnO 2+x . Environmental studies have shown the value of utilizing the chemical signatures of these actinide oxide materials to understand transport following release into the environment. Chemical speciation of actinide-oxide samples may also provide clues as to the age, source, or process history of the material. The scientific challenge is to identify, measure and understand those aspects of speciation of actinide analytes that carry information about material origin and history most relevant to forensics. Here, we will describe our efforts in material synthesis and analytical methods development that we will use to provide the fundamental science to characterize actinide oxide molecular structures for forensic science. Structural properties and initial results to measure structural variability of uranium oxide samples using synchrotron-based X-ray Absorption Fine Structure will be discussed.

Uranium- and plutonium-oxide systems form under a variety of conditions, and these chemical species exhibit some of the most complex behavior of metal oxide systems known. No less intriguing is the ability of AnO{sub 2} (An: U, Pu) to form non-stoichiometric species described as AnO{sub 2+x}. Environmental studies have shown the value of utilizing the chemical signatures of these actinide oxide materials to understand transport following release into the environment. Chemical speciation of actinide-oxide samples may also provide clues as to the age, source, or process history of the material. The scientific challenge is to identify, measure and understand those aspects of speciation of actinide analytes that carry information about material origin and history most relevant to forensics. Here, we will describe our efforts in material synthesis and analytical methods development that we will use to provide the fundamental science to characterize actinide oxide molecular structures for forensic science. Structural properties and initial results to measure structural variability of uranium oxide samples using synchrotron-based X-ray Absorption Fine Structure will be discussed.

  6. A short history of the Australian Society of Soil Science

    Bennison, Linda

    2013-04-01

    In 1955 a resolution, "that the Australian Society of Soil Science be inaugurated as from this meeting" was recorded in Melbourne Australia. The following year in Queensland, the first official meeting of the Society took place with a Federal Executive and Presidents from the Australian Capital Territory, New South Wales, Queensland, South Australian and Victorian branches forming the Federal Council. In later years the executive expanded with the addition of the Western Australia branch in 1957, the Riverina Branch in 1962 and most recently the Tasmania Branch in 2008. The objects of the Society were 1) the advancement of soil science and studies therein with particular reference to Australia and 2) to provide a link between soil scientists and kindred bodies within Australia and between them and other similar organisations in other countries. Membership was restricted to persons engaged in the scientific study of the soil and has grown steadily from to 147 members in 1957 to 875 members in 2012. The first issue of the Society newsletter, Soils News, was published in January 1957 and continued to be published twice yearly until 1996. A name change to Profile and an increase to quarterly publication occurred in 1997; circulation remained restricted to members. The Publications Committee in 1968 determined the Publication Series would be the medium for occasional technical papers, reviews and reports but not research papers and in 1962 the Australian Journal of Soil Research was established by CSIRO in response to continued representations from the Society. By 1960 a draft constitution was circulated to, and adopted by members. The first honorary life membership of the Society was awarded to Dr. J A Prescott. Honorary memberships are still awarded for service to the Society and to soil science and are capped at 25. In 1964 the ISSS awarded honorary membership to Dr. Prescott. Now known as IUSS Honorary members other Australians recognised have been EG Hallsworth

    DNA methylation, which occurs at the 5'-position of the cytosine in CpG dinucleotides, has great potential for forensic identification of body fluids, because tissue-specific patterns of DNA methylation have been demonstrated, and DNA is less prone to degradation than proteins or RNA. Previous studies have reported several body fluid-specific DNA methylation markers, but DNA methylation differences are sometimes low in saliva and vaginal secretions. Moreover, specific DNA methylation markers in four types of body fluids (blood, saliva, semen, and vaginal secretions) have not been investigated with genome-wide profiling. Here, we investigated novel DNA methylation markers for identification of body fluids for use in forensic science using the Illumina HumanMethylation 450K bead array, which contains over 450,000 CpG sites. Using methylome data from 16 samples of blood, saliva, semen, and vaginal secretions, we first selected 2986 hypermethylated or hypomethylated regions that were specific for each type of body fluid. We then selected eight CpG sites as novel, forensically relevant DNA methylation markers: cg06379435 and cg08792630 for blood, cg26107890 and cg20691722 for saliva, cg23521140 and cg17610929 for semen, and cg01774894 and cg14991487 for vaginal secretions. These eight selected markers were evaluated in 80 body fluid samples using pyrosequencing, and all showed high sensitivity and specificity for identification of the target body fluid. We suggest that these eight DNA methylation markers may be good candidates for developing an effective molecular assay for identification of body fluids in forensic science.

    Forensic science is increasingly used to help exonerate the innocent and establishing links between individuals and criminal activities. With increased reliance on scientific services provided by multi-disciplinary (police, medicine, law, forensic science), and multi-organisational in the private and government sectors (health, justice, legal, police) practitioners, the potential for miscommunication resulting unjust outcomes increases. The importance of identifying effective multi-organisational information sharing is to prevent the 'justice silo effect'; where practitioners from different organisations operate in isolation with minimal or no interaction. This paper presents the findings from the second part of the Interfaces Project, an Australia-wide study designed to assess the extent of the justice silos. We interviewed 121 police, forensic scientists, lawyers, judges, coroners, pathologists and forensic physicians. The first paper published in 2013 presented two key findings: first investigative meetings were rare in adult sexual assault cases; second many medical practitioners were semi-invisible in case decision-making with this low level of visibility being due to lawyers, forensic scientists or police not being aware of the role/expertise medical practitioners offer. These findings led to the development of a flowchart model for adult sexual assault that highlights the range of agencies and practitioners typically involved in sexual assault. The rationale for the flowchart is to produce a visual representation of a typical sexual assault investigative process highlighting where and who plays a role in order to minimise the risk of justice silos. This is the second paper in a series of two. Copyright © 2018 Elsevier B.V. All rights reserved.

  10. A former Romanian scientific society: The Society of Physical sciences (1890-1910

    IAVORENCIUC GEORGE ANDREI

    2015-12-01

    Full Text Available The Society of Physical sciences (phisycs, chemistry and mineralogy has been an important Romanian scientific society since its establishment, in 1890 until the middle of the twentieth century. This paper seeks to provide an analysis of its activity in the first two decades of existence, a less studied period, namely how its enterprises contributed to the dissemination and spread of the latest scientific ideas within Romania’s culture. The society was founded at the initiative of some of the most proeminent Romanian scientists of that period and, until the end of the nineteenth century, it expanded its sphere of activity by including sections on mathemathics and natural history. Therefore, its activity, exemplified by public conferences, presentation of members’ personal scientific endeavors, intellectual debates or scientific missions, reflected the general development of physical sciences in Romania in that epoch. This research is based mostly on a close scrutiny of society’s scientific journal.

    Soil complexity, heterogeneity and transferability make it valuable in forensic investigations to help obtain clues as to the origin of an unknown sample, or to compare samples from a suspect or object with samples collected at a crime scene. In a few countries, soil analysis is used in matters from site verification to estimates of time after death. However, up to date the application or use of soil information in criminal investigations has been limited. In particular, comparing bacterial communities in soil samples could be a useful tool for forensic science. To evaluate the relevance of this approach, a blind test was performed to determine the origin of two questioned samples (one from the mock crime scene and the other from a 50:50 mixture of the crime scene and the alibi site) compared to three control samples (soil samples from the crime scene, from a context site 25m away from the crime scene and from the alibi site which was the suspect's home). Two biological methods were used, Ribosomal Intergenic Spacer Analysis (RISA), and 16S rRNA gene sequencing with Illumina Miseq, to evaluate the discriminating power of soil bacterial communities. Both techniques discriminated well between soils from a single source, but a combination of both techniques was necessary to show that the origin was a mixture of soils. This study illustrates the potential of applying microbial ecology methodologies in soil as an evaluative forensic tool. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Bellinfante, Nicolás; Arbelo, Dolores; Rodríguez, Antonio

    2013-04-01

    The Spanish Society of Soil Science (SECS; http://www.secs.com.es) has reached sixty years of existence, after being established in 1947 at the Spanish Council for Scientific Research (CSIC) as an initiative of renowned scientists including José María Albareda, Salvador Rivas Goday, Fernando Burriel, Tomás Alvira and others. However, soil studies in Spain began in the first third of XX century, coordinated by Emilio Huguet del Villar, internationally outstanding researcher who was the President of the Subcommittee for the Mediterranean Region of the International Society Soil Science, with the activities of the Forest Research Institute and the Institute of Mediterranean Soils of the Regional Catalonian Government. With the creation of the CSIC and the Spanish Institute of Soil Science and Agrobiology, directed by José M. Albareda, Soil Science research was promoted in all scientific fields and through the Spanish geography. The SECS is considered equally heiress of previously existing organizations, in particular the Spanish Commission of Soil Science and Phytogeography, created in 1925, which was the Spanish voice in various international organizations and meetings related with Soil Science. After these years, Soil Science has developed considerably, showing a great diversification of fields of study and research and its applications, as well as a growing social awareness of the soil degradation processes and the need to implement measures to protect natural resources nonrenewable on a human scale, and an increasing role of universities and CSIC in Soil Science research. Currently, the SECS is a scientific organization dedicated to promoting the study, knowledge, research and protection of soil resources; spread the scientific importance of soil functions as nonrenewable natural resource in society and promote the interest in its protection; and preserve the knowledge about soils, their management and use, both from productive and environmental perspectives

  19. Value Added: History of Physics in a ``Science, Technology, and Society'' General Education Undergraduate Course

    2016-03-01

    In thirty years of teaching a capstone ``Science, Technology, and Society'' course to undergraduate students of all majors, I have found that, upon entering STS, to most of them the Manhattan Project seems about as remote as the Civil War; few can describe the difference between nuclear and large non-nuclear weapons. With similar lack of awareness, many students seem to think the Big Bang was dreamed up by science sorcerers. One might suppose that a basic mental picture of weapons that held entire populations hostage should be part of informed citizenship. One might also suppose that questions about origins, as they are put to nature through evidence-based reasoning, should be integral to a culture's identity. Over the years I have found the history of physics to be an effective tool for bringing such subjects to life for STS students. Upon hearing some of the history behind (for example) nuclear weapons and big bang cosmology, these students can better imagine themselves called upon to help in a Manhattan Project, or see themselves sleuthing about in a forensic science like cosmology. In this talk I share sample student responses to our class discussions on nuclear weapons, and on cosmology. The history of physics is too engaging to be appreciated only by physicists.

    In order to adequately perform its many diverse tasks as a scholars' society and as the German National Academy of Sciences, the Deutsche Akademie der Naturforscher Leopoldina needs to view itself in a historical context. This can only happen as part of a culture of remembrance which fosters the memory of the Leopoldina's past and subjects this to a critical analysis in the context of the history of science and academies. The newly founded Leopoldina Study Center for the History of Science and Science Academies is to be a forum that pursues established forms of historical research at the Leopoldina, organizes new scientific projects, and presents its findings to the public. The aim is to involve as many Leopoldina members as possible from all of its disciplines, as well as to collaborate with national and international partners.

  3. A Brief History of the Soil Science Society of America

    Science.gov (United States)

    Brevik, Eric C.

    2013-04-01

    The Soil Science Society of America (SSSA) was officially born on November 18, 1936 at the Mayflower Hotel in Washington, D.C. with Richard Bradfield as the first President. SSSA was created from the merger of the American Soil Survey Association and the Soils Section of American Society of Agronomy (ASA). Six sections were established: 1) physics, 2) chemistry, 3) microbiology, 4) fertility, 5) morphology, and 6) technology, and total membership was less than 200. The first issue of SSSA Journal, then called SSSA Proceedings, published 87 items totaling 526 pages. The first recorded bank balance for SSSA was at the end of the 1937-38 fiscal year, and showed the Society to be worth 1,300.03. The Soils Section of ASA became the official American section of the International Society of Soil Science in 1934, and the new SSSA inherited that distinction which it retains to this day. SSSA has grown significantly since those early days. The original six sections have grown to 11 divisions, and some of those divisions have changed their names to reflect changes occurring within soil science. For example, the original section 5, morphology, is now Division S05 - Pedology after spending many years under other names such as Division V - Soil Classification and Division S-5 - Soil Genesis, Morphology, and Classification. SSSA was incorporated in the State of Wisconsin, USA on 22 January, 1952. Several awards have been developed to recognize achievement in the field of soil science, including the SSSA Presidential Award, Don and Betty Kirkham Soil Physics Award, Emil Truog Soil Science Award, International Soil Science Award, Irrometer Professional Certification Service Award, L.R. Ahuja Ag Systems Modeling Award, Marion L. and Chrystie M. Jackson Soil Science Award, Soil Science Applied Research Award, Soil Science Distinguished Service Award, Soil Science Education Award, Soil Science Industry and Professional Leadership Award, Soil Science Research Award, and SSSA Early

  4. Knowledge Translation: Moving Proteomics Science to Innovation in Society.

    Holmes, Christina; McDonald, Fiona; Jones, Mavis; Graham, Janice

    2016-06-01

    Proteomics is one of the pivotal next-generation biotechnologies in the current "postgenomics" era. Little is known about the ways in which innovative proteomics science is navigating the complex socio-political space between laboratory and society. It cannot be assumed that the trajectory between proteomics laboratory and society is linear and unidirectional. Concerned about public accountability and hopes for knowledge-based innovations, funding agencies and citizens increasingly expect that emerging science and technologies, such as proteomics, are effectively translated and disseminated as innovation in society. Here, we describe translation strategies promoted in the knowledge translation (KT) and science communication literatures and examine the use of these strategies within the field of proteomics. Drawing on data generated from qualitative interviews with proteomics scientists and ethnographic observation of international proteomics conferences over a 5-year period, we found that proteomics science incorporates a variety of KT strategies to reach knowledge users outside the field. To attain the full benefit of KT, however, proteomics scientists must challenge their own normative assumptions and approaches to innovation dissemination-beyond the current paradigm relying primarily on publication for one's scientific peers within one's field-and embrace the value of broader (interdisciplinary) KT strategies in promoting the uptake of their research. Notably, the Human Proteome Organization (HUPO) is paying increasing attention to a broader range of KT strategies, including targeted dissemination, integrated KT, and public outreach. We suggest that increasing the variety of KT strategies employed by proteomics scientists is timely and would serve well the omics system sciences community.

    Fukui, Ken'ichi

    This is a special lecture at the 30th anniversary of JICST. To develop science-and-te chnology-oriented society it is important to evaluate and select infinite information resources on science and technology, and to reorganize and apply them. This also relates to humanity. For the future, we have to establish scientific ethics that can exceed the expedience of science and technology. To be concrete, we have to create new industrial value that recovers and reclaims natural resources which men had wasted so far, and we have to establish a new technology to distribute maldistributed industrial benefits equally. And then, the selfcontrol of the human aiming at the harmony of nature and man will secure human liberty, and it will be done by the good function of man's brain.

    Significant advances in science should be given to addressing the needs of society and the historical context of the territories. Although technological developments that began with modernity and the industrial revolution allowed human beings to control the resources of nature to put to your service without limits, it is clear that the crisis of the prevailing development models manifest themselves in many ways but with three common denominators: environmental degradation, social injustice and extreme poverty. Consequently, today should not be possible to think a breakthrough in the development of science without addressing global environmental problems and the deep social injustices that increase at all scales under the gaze, impassively in many occasions, of formal science.

  7. Geoethics and Forensic Geology

    Donnelly, Laurance

    2017-04-01

    The International Union of Geological Sciences (IUGS), Initiative on Forensic Geology (IFG) was set up in 2011 to promote and develop the applications of geology to policing and law enforcement throughout the world. This includes the provision of crime scene examinations, searches to locate graves or items of interest that have been buried beneath the ground surface as part of a criminal act and geological trace analysis and evidence. Forensic geologists may assist the police and law enforcement in a range of ways including for example; homicide, sexual assaults, counter terrorism, kidnapping, humanitarian incidents, environmental crimes, precious minerals theft, fakes and fraudulent crimes. The objective of this paper is to consider the geoethical aspects of forensic geology. This includes both delivery to research and teaching, and contribution to the practical applications of forensic geology in case work. The case examples cited are based on the personal experiences of the authors. Often, the technical and scientific aspect of forensic geology investigation may be the most straightforward, after all, this is what the forensic geologist has been trained to do. The associated geoethical issues can be the most challenging and complex to manage. Generally, forensic geologists are driven to carry-out their research or case work with integrity, honesty and in a manner that is law abiding, professional, socially acceptable and highly responsible. This is necessary in advising law enforcement organisations, society and the scientific community that they represent. As the science of forensic geology begins to advance around the world it is desirable to establish a standard set of principles, values and to provide an agreed ethical a framework. But what are these core values? Who is responsible for producing these? How may these become enforced? What happens when geoethical standards are breached? This paper does not attempt to provide all of the answers, as further work

Finally, the analysis is exemplified in two cases: food consumption and energy consumption.

  9. Applications of physiological bases of ageing to forensic sciences. Estimation of age-at-death.

    Science.gov (United States)

    C Zapico, Sara; Ubelaker, Douglas H

    2013-03-01

    Age-at-death estimation is one of the main challenges in forensic sciences since it contributes to the identification of individuals. There are many anthropological techniques to estimate the age at death in children and adults. However, in adults this methodology is less accurate and requires population specific references. For that reason, new methodologies have been developed. Biochemical methods are based on the natural process of ageing, which induces different biochemical changes that lead to alterations in cells and tissues. In this review, we describe different attempts to estimate the age in adults based on these changes. Chemical approaches imply modifications in molecules or accumulation of some products. Molecular biology approaches analyze the modifications in DNA and chromosomes. Although the most accurate technique appears to be aspartic acid racemization, it is important to take into account the other techniques because the forensic context and the human remains available will determine the possibility to apply one or another methodology.

    Microfluidic chips offer significant speed, cost, and sensitivity advantages, but numerous parameters must be optimized to provide microchip electrophoresis detection. Experiments were conducted to study the factors, including sieving matrices (the concentration and type), surface modification, analysis temperature, and electric field strengths, which all impact the effectiveness of microchip electrophoresis detection of DNA samples. Our results showed that the best resolution for ssDNA was observed using 4.5% w/v (7 M urea) lab-fabricated LPA gel, dynamic wall coating of the microchannel, electrophoresis temperatures between 55 and 60°C, and electrical fields between 350 and 450 V/cm on the microchip-based capillary electrophoresis (μCE) system. One base-pair resolution could be achieved in the 19-cm-length microchannel. Furthermore, both 9947A standard genomic DNA and DNA extracted from blood spots were demonstrated to be successfully separated with well-resolved DNA peaks in 8 min. Therefore, the microchip electrophoresis system demonstrated good potential for rapid forensic DNA analysis. © 2017 American Academy of Forensic Sciences.

  11. Science, truth, and forensic cultures: the exceptional legal status of DNA evidence.

    Science.gov (United States)

    Lynch, Michael

    2013-03-01

    Many epistemological terms, such as investigation, inquiry, argument, evidence, and fact were established in law well before being associated with science. However, while legal proof remained qualified by standards of 'moral certainty', scientific proof attained a reputation for objectivity. Although most forms of legal evidence (including expert evidence) continue to be treated as fallible 'opinions' rather than objective 'facts', forensic DNA evidence increasingly is being granted an exceptional factual status. It did not always enjoy such status. Two decades ago, the scientific status of forensic DNA evidence was challenged in the scientific literature and in courts of law, but by the late 1990s it was being granted exceptional legal status. This paper reviews the ascendancy of DNA profiling, and argues that its widely-heralded objective status is bound up with systems of administrative accountability. The 'administrative objectivity' of DNA evidence rests upon observable and reportable bureaucratic rules, records, recording devices, protocols, and architectural arrangements. By highlighting administrative sources of objectivity, this paper suggests that DNA evidence remains bound within the context of ordinary organisational and practical routines, and is not a transcendent source of 'truth' in the criminal justice system.

    We now have a confusing set of five commonly used terms for the application of Earth evidence in forensic science. This confusion is resulting in Earth scientists who use these methods mentioning different terms, sometimes for the same type of study. Likewise, forensic scientists, police/law enforcement officers and those employed by courts of law are becoming confused as to what each term means. A nomenclatural framework (based on the first use of each term) is proposed to encourage consistency in the use of terminology. Generally, the number of Earth science applications has grown through time, from soil and sediment analysis to remote sensing and GIS. The issue of where forensic biology and microbiology sits with these uses of Earth evidence is considered. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

  14. From 'implications' to 'dimensions': science, medicine and ethics in society.

    Science.gov (United States)

    Pickersgill, Martyn D

    2013-03-01

    Much bioethical scholarship is concerned with the social, legal and philosophical implications of new and emerging science and medicine, as well as with the processes of research that under-gird these innovations. Science and technology studies (STS), and the related and interpenetrating disciplines of anthropology and sociology, have also explored what novel technoscience might imply for society, and how the social is constitutive of scientific knowledge and technological artefacts. More recently, social scientists have interrogated the emergence of ethical issues: they have documented how particular matters come to be regarded as in some way to do with 'ethics', and how this in turn enjoins particular types of social action. In this paper, I will discuss some of this and other STS (and STS-inflected) literature and reflect on how it might complement more 'traditional' modes of bioethical enquiry. I argue that STS might (1) cast new light on current bioethical issues, (2) direct the gaze of bioethicists towards matters that may previously have escaped their attention, and (3) indicate the import not only of the ethical implications of biomedical innovation, but also how these innovative and other processes feature ethics as a dimension of everyday laboratory and clinical work. In sum, engagements between STS and bioethics are increasingly important in order to understand and manage the complex dynamics between science, medicine and ethics in society.

  15. European Meteorological Society and education in atmospheric sciences

    EMS is supporting the exchange of information in the area of education in atmospheric sciences as one of its priority and organizing the educational sessions during EMS annual meetings as a good occasion for such an exchange. Brief thought will be given to the fate of the series of International Conferences on School and Popular Meteorological and Oceanographic Education - EWOC (Education in Weather, Ocean and Climate) and to the project oriented basis of further cooperation in education in atmospheric sciences across Europe. Another tool of EMS is the newly established and developed EDU portal of EMS. In most European countries the process of integration of education at university level was started after Bologna Declaration with the objective to have the system where students on some level could move to another school, or rather university. The goal is to achieve the compatibility between the systems and levels in individual countries to have no objections for students when transferring between the European countries. From this point of view EMS is trying to provide the information about the possibility of education in meteorology and climatology in different countries in centralised form, with uniform shape and content, but validated on national level. In most European countries the necessity of education in Science and Mathematics to achieve higher standard and competitiveness in research and technology development has been formulated after the Lisboa meeting. The European Meteorological Society is trying to follow this process with implication to atmospheric sciences. One of the important task of the EMS is the activity to promote public understanding of meteorology (and sciences related to it), and the ability to make use of it, through schools and more generally. One of the elements of EMS activity is the analysis of the position of atmospheric science in framework of curricula in educational systems of European countries as well as in more general sense, the

  16. Academic Training turns to matters of science and society

    CERN Multimedia

    2001-01-01

    Once again, CERN has opened its doors to matters of science and society. A recent academic training lecture series tackled the thorny issue of arms control. Although an issue far from normal training needs of CERN personnel, the series was well attended. Aseries of lectures about arms control at CERN? Surely some mistake! But there are many reasons why one of the world's most important physics laboratories should consider such weighty political and ethical matters - not least the concern for the issues felt by members of the CERN community. A large number of people followed the full series of lectures on arms control and disarmament by Francesco Calogero, Professor of theoretical physics at Rome's 'La Sapienza' University, demonstrating that CERN people are not only interested in purely scientific matters, but also in the implications for society. Professor Calogero, a former Secretary General of Pugwash1) and currently Chairman of the Pugwash Council, observed that, 'even if I dealt, albeit tersely, with the...

    Use of DNA in forensic science will be significantly influenced by new technology in coming years. Massively parallel sequencing and forensic genomics will hasten the broadening of forensic DNA analysis beyond short tandem repeats for identity towards a wider array of genetic markers, in applications as diverse as predictive phenotyping, ancestry assignment, and full mitochondrial genome analysis. With these new applications come a range of legal and policy implications, as forensic science touches on areas as diverse as 'big data', privacy and protected health information. Although these applications have the potential to make a more immediate and decisive forensic intelligence contribution to criminal investigations, they raise policy issues that will require detailed consideration if this potential is to be realised. The purpose of this paper is to identify the scope of the issues that will confront forensic and user communities. Copyright © 2017 The Chartered Society of Forensic Sciences. All rights reserved.

  18. An overview to the investigative approach to species testing in wildlife forensic science

    Science.gov (United States)

    2011-01-01

    The extent of wildlife crime is unknown but it is on the increase and has observable effects with the dramatic decline in many species of flora and fauna. The growing awareness of this area of criminal activity is reflected in the increase in research papers on animal DNA testing, either for the identification of species or for the genetic linkage of a sample to a particular organism. This review focuses on the use of species testing in wildlife crime investigations. Species identification relies primarily on genetic loci within the mitochondrial genome; focusing on the cytochrome b and cytochrome oxidase 1 genes. The use of cytochrome b gained early prominence in species identification through its use in taxonomic and phylogenetic studies, while the gene sequence for cytochrome oxidase was adopted by the Barcode for Life research group. This review compares how these two loci are used in species identification with respect to wildlife crime investigations. As more forensic science laboratories undertake work in the wildlife area, it is important that the quality of work is of the highest standard and that the conclusions reached are based on scientific principles. A key issue in reporting on the identification of a particular species is a knowledge of both the intraspecies variation and the possible overlap of sequence variation from one species to that of a closely related species. Recent data showing this degree of genetic separation in mammalian species will allow greater confidence when preparing a report on an alleged event where the identification of the species is of prime importance. The aim of this review is to illustrate aspects of species testing in wildlife forensic science and to explain how a knowledge of genetic variation at the genus and species level can aid in the reporting of results.

    2003-03-01

    At the beginning of the 21th century, the use of nuclear power has assumed very serious dimensions, because there are many problems not only safety technologies but also action of technical expert. The situation and problems of nuclear power are explained. It consists of six chapter as followings; introduction, history and R and D of nuclear power, paradigm change of nuclear science and engineering, energy science, investigation of micro world, how to research and development and education and training of special talent. The improvement plans and five proposals are stated as followings; 1) a scholar and engineer related to nuclear power have to understand ethics and build up closer connection with person in the various fields. 2) Nuclear power generation and nuclear fuel cycle are important in future, so that they have to be accepted by the society by means of opening to the public. Safety science, anti-pollution measurements, treatment and disposal of radioactive waste and development of new reactor and fusion reactor should be carried out. 3) It is necessary that the original researches of quantum beam and isotope have to step up. 4) The education of nuclear science and technology and upbringing special talent has to be reconstructed. New educational system such as 'nuclear engineering course crossing with many universities' is established. 5) Cooperation among industry, academic world and government. (S.Y.)

    Science and the law are considered to be the two main shaping forces in modern societies. The Regional Seminars on Forensic Physics are organized by (mostly CNEA) scientists in Bariloche with a twofold purpose: to increase the participation of researchers as experts witnesses in the solution of legal problems, and to make judges aware of facilities and techniques that might prove useful. Some of the contributions to the last seminar are discussed, ranging from the numerical simulation of mayor explosions to the behavior of snow avalanches, and from the proper control of a trace laboratory to the distribution of words in the plays of Shakespeare.

    2015-11-01

    To analyze, interpret and evaluate microscopic images, used in medical diagnostics and forensic science, video images for educational purposes were made with a very high resolution of 4096 × 2160 pixels (4K), which is four times as many pixels as High-Definition Video (1920 × 1080 pixels). The unprecedented high resolution makes it possible to see details that remain invisible to any other video format. The images of the specimens (blood cells, tissue sections, hair, fibre, etc.) are recorded using a 4K video camera which is attached to a light microscope. After processing, this resulted in very sharp and highly detailed images. This material was then used in education for classroom discussion. Spoken explanation by experts in the field of medical diagnostics and forensic science was also added to the high-resolution video images to make it suitable for self-study. © 2015 The Authors.

  3. Science and society: The benefits of scientific collaboration

    CERN Multimedia

    2003-01-01

    The guest speaker at the next Science and Society symposium is no stranger to CERN. He is, in fact, Sir Chris Llewellyn Smith, Director General of CERN from 1994 to 1998. His topic is one with which he is particularly familiar, having "lived" it throughout his time at CERN: international scientific collaboration and its advantages. International scientific collaboration is essential in a wide range of areas and for a large number of reasons: scientific problems have no frontiers; certain subjects are so complex that they require the expertise of numerous countries; certain types of research, such as that carried out at CERN, cannot be pursued by one nation on its own. However, scientific collaboration is not only beneficial to science itself. This is the point Chris Llewellyn Smith intends to demonstrate in his address. Scientific collaboration can help to build bridges between societies and act as a spur to the development of certain countries. It can even help to diminish conflicts in certain cases. The his...

    2012-01-01

    The institution of the medical expert was already known in the early Polish courts. The first Chair of Forensic Medicine on Polish soil was established in 1805 at the Jagiellonian University in Cracow and has existed until today. Among its most prominent forensic scientists are Prof. Fryderyk Hechell (1795-1851), Prof. Leon Blumenstock (1838-1895), who was the first to give regular lectures on forensic medicine for law students, and Prof. Leon Wachholz (1867-1941), who was a student of both Prof. Blumenstock and Prof. Eduard von Hofmann (1837-1897), under whose supervision he worked in Vienna. Under his guidance and supervision, he started to collect material for his habilitation. At that time, Hofmann was considered the pioneer of experimental research in forensic medicine. In Vienna, Wachholz was a guest scientist not only with Prof. von Hofmann, but also in the Psychiatric Hospital of Prof. Richard von Krafft-Ebing. After his return to Cracow, he was head of the Institute of Forensic Medicine of the Jagiellonian University for several decades. Apart from forensic medicine in the strict sense of the word, he also worked in the fields now known as criminalistics, forensic psychiatry and criminology. In these latter fields, the influence of Krafft-Ebing was still noticeable. Three students of Wachholz became professors of forensic medicine: Jan Olbrycht, Stanislaw Horoszkiewicz and Włodzimierz Sieradzki. Their students founded a whole generation of forensic scientists. Today, all Polish forensic scientists are either directly or indirectly students of Professor Wachholz' successors.

  5. New Roles for Scientists and Science Societies to Improve Science Communication

    Schneider, S. H.

    2008-12-01

    Should North American Scientists and Science Societies continue with current communication programs or is there a need for expanded and or altered roles in Science Communication? If current practices are working, why is discourse outside of science societies so often misinformed and distorted on environmental change issues that are clearly defined and described within the science community? Climate change is one example there is virtual unanimity and overwhelming evidence from the scientific community that the Earth is warming rapidly and humans are an important cause, but there is confusion in the media and the public, in part due to disinformation campaigns by greenhouse gas polluters and privately funded "Think Tanks." A summary discussion will be presented that addresses many of the ideas and issues brought forward by colleagues in science, science communication and education. Scientists and Science Societies must re-establish objectivity in science information communication to educators, the media and the public. Recommendations on directions will be a key outcome of this presentation.

    Full Text Available It is essential to understand the hurdles, motivation, and other issues affecting scientists' active participation in science communication to bridge the gap between science and society. This study analyzed 1115 responses of Japanese scientists regarding their attitudes toward science communication through a questionnaire focusing on the field of stem cell and regenerative medicine. As a result, we found that scientists face systemic issues such as lack of funding, time, opportunities, and evaluation systems for science communication. At the same time, there is a disparity of attitudes toward media discourse between scientists and the public.

    2010-05-01

    The YES Network is an international association of early-career geoscientists who are primarily under the age of 35 years and are currently engaged in the geosciences in organizations from across the world. The YES Network was formed as a result of the International Year of Planet Earth in 2007. The YES Network aims to establish an interdisciplinary global network of individuals committed to solving these challenges, and furthering the IYPE motto of "Earth Sciences for Society". In 2009, in collaboration with the IYPE and under the patronage of UNESCO, the YES Network organized its first international Congress at the China University of Geosciences in Beijing, China. The Congress focused on climate, environmental and geoscience challenges facing today's society, as well as career and academic pathway challenges faced by early-career geoscientists. More than 300 young geoscientists from across the world attended the conference to present their research and participate in the oral, poster, and roundtable symposia. The roundtable symposia engaged senior and early-career geoscientists via presentations, panel discussions, and working group sessions. These symposia were broadcast as ‘live' webinars to increase international participation. As a result, 41 "virtual" participants from 10 countries and 16 "virtual" speakers from 5 countries were able to participate in these discussions. Since October, the YES Network has continued to expand its membership and develop more projects aligned with the "Earth Sciences for Society" motto. The YES Network is continuing to develop its website and social media networks to increase communication between YES Network members on local, regional and international scales, and it is developing resources to aid early-career geoscientists with opportunities for professional development, international collaboration, and involvement in outreach activities. Members of the YES Network are actively forming connections between the YES Network

    2000-01-01

    In the final Science and Society Colloquium of 2000, Professor Mark Ellisman of the University of California in San Diego will examine the ways that information technology is bringing about changes in the field of neuroscience. Professor Ellisman is Director of the US National Center for Microscopy and Imaging Research, and is involved in several projects that merge advanced computing and networking technologies with advanced forms of microscopy. These include the National Institutes of Health (NIH) sponsored Human Brain Project that aims to fill the gap in our understanding of how low-level operations of individual neurons scale up to higher-level mental activity. In his talk, Professor Ellisman will describe the promise offered by advanced informatics. Parallel processing and distributed computing, for example, are allowing new advances in visualising and understanding 3-D neuronal structures, while progress in the field of remote access to highly specialized and expensive instruments - like high voltage ...

    2017-09-01

    A recent report by the US President's Council of Advisors on Science and Technology (PCAST), (2016) has made a number of recommendations for the future development of forensic science. Whereas we all agree that there is much need for change, we find that the PCAST report recommendations are founded on serious misunderstandings. We explain the traditional forensic paradigms of match and identification and the more recent foundation of the logical approach to evidence evaluation. This forms the groundwork for exposing many sources of confusion in the PCAST report. We explain how the notion of treating the scientist as a black box and the assignment of evidential weight through error rates is overly restrictive and misconceived. Our own view sees inferential logic, the development of calibrated knowledge and understanding of scientists as the core of the advance of the profession. Copyright © 2017 Elsevier B.V.

  13. The concept of a 'microstructural fingerprint' for the characterization of samples in nuclear forensic science

    International Nuclear Information System (INIS)

    Ray, I.L.F.; Schubert, A.; Wallenius, M.

    2002-01-01

    In the examination of unknown specimens of nuclear materials the primary parameter of importance is the 'Isotopic Fingerprint' of the sample, mainly the ratios of the different isotopes of U and Pu which are present. In some cases, however, where no clear isotopic signature is found, or where there is a mixture of materials present, the isotopic fingerprint alone is not sufficient for a unique identification to be made. In this paper the concept of a 'Microstructural Fingerprint' of a sample is proposed and developed, which is complementary to the 'Isotopic Fingerprint' for the characterisation of materials which are under investigation in the field of nuclear forensic science. The proposal combines the techniques of Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Energy Dispersive X-ray Analysis (EDX), to define the microstructure of a suspect sample, a combination of techniques which has not been used before in nuclear forensic science. The microstructural information is particularly important in the case of powder samples, for the following reasons: 1) An essential prerequisite to an isotopic analysis, for example by Thermal Ionisation Mass Spectrometry (TIMS), is the information whether a powder sample consists of a single component, or is a mixture of several distinct components. If the material is multicomponent it must be separated and the individual components analysed separately. 2) Powder samples mainly represent precursor stages in the nuclear fuel cycle, and the microstructural analysis gives information on the production process and conditions (for example, the grain size in PuO 2 platelets produced by the calcination of oxalate precipitate, and the size and thickness distributions of the platelets themselves). 3) Powder samples can be mixed with other compounds with the deliberate intention of confusing the chemical or isotopic analysis of suspect materials. However the microstructural fingerprint of a component cannot

  14. Health and Illness in History, Science and Society

    Directory of Open Access Journals (Sweden)

    Miriam Rovesti

    2018-01-01

    Full Text Available Health is a fundamental human right. The World Health Organization defines it as a "state of complete physical, psychological and social well - being and not merely the absence of disease or infirmity". The health of individuals, however, is also linked to the environment in which they live and especially to their ability to adapt and integrate into their life context. The relationship with the environment is extremely important because it is that interaction that outlines the concept of normality compared to pathology. Such normality needs to be contextualised by gender, geographical origin and by the individuals’ living conditions: as a matter of fact, what is normal for a young person may differ from what is normal for a senior one. That is to say, the concept of health is indeed relative and it is the result of an interesting evolution of the concept of illness. From the first approaches - dealing with the mere treatment of the symptoms - to the promise of a free-from-pain society, science and economics have played a significant role in redefining the dualism health/ illness. The article reflects on these two concepts, health and illness, in history and nowadays, and discusses the future of the medical science.

    2006-11-01

    ABSTRACT Workshops are used for educating law enforcement personnel on the application of entomological, anthropological, and botanical techniques to gather forensically important information from a body recovery site. From 8 to 11 June 2004, such a workshop was conducted in the metropolitan area of Charlotte, NC, by the American Academy of Applied Forensics at Central Piedmont Community College. For this workshop, three pig carcasses weighing individually between 40 and 60 kg were placed in the field 4 June, whereas three pigs similar in size were placed in the field 7 June. During the afternoon session on 11 June, workshop participants collected three Chrysomya rufifacies (Macquart) (Diptera: Calliphoridae) third instar larvae from a pig carcass placed in the field on 7 June. These data represent the first records of this forensically important insect in North Carolina; furthermore, these data provide evidence of this species expansion into new geographic regions of the United States. This finding is an example of the benefits derived from an experiential and interdisciplinary approach to educating death scene investigators. Learners acquired new knowledge, put it into practice through the "body" recovery exercise, and ultimately contributed to science by way of the discovery and first documentation of a forensically important insect previously not known to inhabit North Carolina.

    2013-04-01

    The Soil Science Society of America created its K12 Committee in 2006 in part to compliment the Dig It! The Secrets of Soil exhibit that opened in July 2008 at the Smithsonian's Institution's Nation Museum of Natural History (of which SSS was a founding sponsor). The committee's work began quickly with a website designed to provide resources for K12 teachers. The first accomplishments included reviewing and posting links to web based information already available to teachers. These links were sorted by subject and grade level to make it easier for teachers to navigate the web and find what they needed quickly. Several presentations and lessons designed for K12 teachers were also posted at this time. Concurrent with this effort a subcommittee review and organized the national teaching standards to show where soils could fit into the overall K12 curriculum. As the website was being developed another subcommittee developed a soils book (Soil! Get the Inside Scoop, 2008) to further compliment the Dig It! exhibit. This was a new endeavor for SSSA having never worked with the non-academic audience in developing a book. Peer-reviews of this book included not only scientist but also students in order to make sure the book was attractive to them. Once the book was published and the website developed it became clear more outreach was needed. SSSA K12 Committee has attended both the National Science Teachers Association (since 2008) the USA Science and Engineering Festival (since 2010) with exhibits and workshops. It has cooperated and contributed to the American Geologic Institutes' Earth Science Week materials with brochures and lesson plans and with National Association of Conservation Districts by providing peer-review and distribution of materials. The most recent developments from the committee include a web redesign that is more student and teacher friendly, the development of a peer-review system to publish K12 Lesson Plans, and finally the publication of a new soils

    From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outward to a region far beyond Pluto where the Sun's influence wanes, advances during the past decade in space physics and solar physics the disciplines NASA refers to as heliophysics have yielded spectacular insights into the phenomena that affect our home in space. This report, from the National Research Council's (NRC's) Committee for a Decadal Strategy in Solar and Space Physics, is the second NRC decadal survey in heliophysics. Building on the research accomplishments realized over the past decade, the report presents a program of basic and applied research for the period 2013-2022 that will improve scientific understanding of the mechanisms that drive the Sun's activity and the fundamental physical processes underlying near-Earth plasma dynamics, determine the physical interactions of Earth's atmospheric layers in the context of the connected Sun-Earth system, and enhance greatly the capability to provide realistic and specific forecasts of Earth's space environment that will better serve the needs of society. Although the recommended program is directed primarily to NASA (Science Mission Directorate -- Heliophysics Division) and the National Science Foundation (NSF) (Directorate for Geosciences -- Atmospheric and Geospace Sciences) for action, the report also recommends actions by other federal agencies, especially the National Oceanic and Atmospheric Administration (NOAA) those parts of NOAA charged with the day-to-day (operational) forecast of space weather. In addition to the recommendations included in this summary, related recommendations are presented in the main text of the report.

    2014-05-01

    Brownfield Action (BA) is a web-based, interactive, three dimensional digital space and learning simulation in which students form geotechnical consulting companies and work collectively to explore problems in environmental forensics. Created at Barnard College (BC) in conjunction with the Center for New Media Teaching and Learning at Columbia University, BA has a 12-year history at BC of use in one semester of a two-semester Introduction to Environmental Science course that is taken by more than 100 female undergraduate non-science majors to satisfy their science requirement. The pedagogical methods and design of the BA model are grounded in a substantial research literature focused on the design, use, and effectiveness of games and simulation in education. The successful use of the BA simulation at BC and 14 other institutions in the U.S. is described in Bower et al. (2011 and 2014). Soon to be taught online to non-traditional undergraduate students, BA has 15 modules that include a reconnaissance survey; scale; topographic, bedrock, and water table maps; oral and written reports from residents and the municipal government; porosity and permeability measurements of the regolith (sand) in the area of interest; hydrocarbon chemistry; direction and velocity of groundwater flow; and methods of geophysical exploration (soil gas, ground penetrating radar, magnetic metal detection, excavation, and drilling). Student performance is assessed by weekly exercises and a semester ending Environmental Site Assessment Phase I Report that summarizes the individual and collective discoveries about a contaminated subsurface plume that emanates from a leaking underground storage tank at a gasoline station upgrade from the water well that serves the surrounding community. Texts for the course are Jonathan Harr's A Civil Action and Rachel Carson's Silent Spring, which are accompanied by questions that direct the reading.

    Building learning communities to engage the public in identifying and solving local and regional environmental problems is the vision of the newly created Northern Great Plains Center for People and the Environment at the University of North Dakota. The Center serves as an Environmental Information Bridge between science and society for citizens of the region, providing information, data, and value-added remote sensing products to precision agriculture, sustainable forestry, Native American land managers, and K-lifetime educators. Guided by the needs of end users, the new Center is a prototype for a national infrastructure that meets ESE's objective to "expand and accelerate the realization of economic and societal benefits from Earth science, information, and technology". The scientific community has been good at converting raw data into useful information. However, a serious communications gap exists between the communities of scientists and non-scientists. The new Center bridges this gap, creating a many-to-many exchange of information among those who learn first about the environment and those who will put those lessons to work for their economic welfare, the betterment of the quality of their lives, and the benefit of their descendants. A major outreach component of the Center, written and produced at UND, is Our Changing Planet, a public television series aimed at increasing viewers' awareness of environmental and climate change issues. Now carried by approximately 30 public television stations the series is distributed nationwide by the National Education Television Association. The Center has also recently established a partnership with StormCenter.com, LLC, a multimedia company and fellow partner in NASA's Federation of Earth Science Information Partners that uses leading-edge technology to deliver information about the environment to regional television stations. Service to the media provides a vital link between science and the public, as local weather

    Closed circuit television (CCTV) footage is often available from crime scenes and may be used to compare perpetrators with suspects. Usually, the footage comprises incomplete gait cycles at different velocities, making gait pattern identification from crimes difficult. This study investigated the concurrence of joint angles throughout a gait cycle at three different velocities (3.0, 4.5, 6.0 km/h). Six datasets at each velocity were collected from 16 men. A variability range VR throughout the gait cycle at each velocity for each joint angle for each person was calculated. The joint angles at each velocity were compared pairwise, and whenever this showed values within the VR of this velocity, the case was positive. By adding the positives throughout the gait cycle, phases with high and low concurrences were located; peak concurrence was observed at mid-stance phase. Striving for the same velocity for the suspect and perpetrator is recommended. © 2014 American Academy of Forensic Sciences.

    Full Text Available There are three fundamental aspects in every Indian Society, constantly quarrelling, contradicting and compromising one another every time and contributing pollution at alarming rate. They are cultural, secular and religious aspects. Understanding the Interplay of these three aspects can give us valuable information regarding the country’s spiritual forwardness and its social backwardness; ultimately relieve us from the mystery of Indian system. In every aspect, poverty is constant and pollution is dynamic. All Indians are struggling for existence in everyday life. Economy and Ecology are another two aspects, which exploiting the natural resources. Traditionally and technologically, people of India follow religious as well as scientific sentiments. Gap in between poor and rich are widening, inspiring controversy and increasing crime rate. Women are more vulnerable facing insecurity of life problem. Political system is always dominating aspect and acting as opportunistic, parasitic in nature. Knowledge and intelligence of Indians in mother land are vain; where as in foreign lands it is gainful. Brain drain is one more additional problem in recent years in India. Here Education system is in dilemma position and failed to empower the 60% youth in progressive direction, which is a largest in the world. Now India is suffering with falsehood and false prestige. The seventy years of independence and self-rule are fruitless more over throwing into debt nation with uncontrolled over population, poverty and pollution pang. Religion without superstitions and Science without side effects are impossible in Indian Society. In this paper researcher investigates the real life problems in India for further rectification. With a view to overcome this pathetic situation in India a new nationalistic and socialistic dimension of life-saver concept was identified namely Yogic Environmentalism [YE] which is an unique journey of humans through their interior

    Odour of the animal or human corpses immediately after death is very attractive for insects and other invertebrates. Blue and green bottle flies from the Calliphoridae family are the first colonizers of cadaver and immediately later necrophagous Diptera from the Sarcophagidae family settle on the same corpse. It is essential to determine the time past after death for elucidating the event in case of the homicide or suspicious death, and it is directly proportional to the post mortem interval expected time, which is based upon the speed of the larval growth. In this article, we purposed to stress the special interest of forensic entomology for the scientists who will apply this science in their forensic researches and case studies, and also to provide information to our judges, prosecutors and law enforcement agents in order to consider the entomological samples to be reliable and applicable evidences as biological stains and hairs. We are of the opinion that if any forensic entomologist is called to the crime scene or if the evidences are collected and then delivered to an entomologist, the forensic cases will be elucidated faster and more accurately.

    2013-05-01

    This study analyzes the beliefs about science-technology-society, and other Nature of Science (NOS) themes, of a large sample (613) of Spanish pre- and in-service secondary education teachers through their responses to 30 items of the Questionnaire of Opinions on Science, Technology and Society. The data were processed by means of a multiple response model to generate the belief indices used as the bases for subsequent quantitative and qualitative analyses. Other studies have reported a negative profile of teachers' understanding in this area, but the diagnosis emerging from the present work is more complex. There was a mix of appropriate beliefs coexisting with others that are inappropriate on the topics analyzed. The overall assessment, however, is negative since clearly teachers need to have a better understanding of these questions. There were scant differences between the pre- and in-service teachers, and hence no decisive evidence that the practice of teaching contributes to improving the in-service teachers' understanding. These results suggest there is an urgent need to bring the initial and continuing education of science teachers up to date to improve their understanding of these topics of science curricula, and thus improve the teaching of science.

    Using as a case study the forensic comparison of images for purposes of identification, this essay considers how the history, philosophy and sociology of science might help courts to improve their responses to scientific and technical forms of expert opinion evidence in ways that are more consistent with legal system goals and values. It places an emphasis on the need for more sophisticated models of science and expertise that are capable of helping judges to identify sufficiently reliable types of expert evidence and to reflexively incorporate the weakness of trial safeguards and personnel into their admissibility decision making.

    Abstract This article examines the role that vernacular notions of racialized-regional difference play in the constitution and stabilization of DNA populations in Colombian forensic science, in what we frame as a process of public science. In public science, the imaginations of the scientific world and common-sense public knowledge are integral to the production and circulation of science itself. We explore the origins and circulation of a scientific object--'La Tabla', published in Paredes et al. and used in genetic forensic identification procedures--among genetic research institutes, forensic genetics laboratories and courtrooms in Bogotá. We unveil the double life of this central object of forensic genetics. On the one hand, La Tabla enjoys an indisputable public place in the processing of forensic genetic evidence in Colombia (paternity cases, identification of bodies, etc.). On the other hand, the relations it establishes between 'race', geography and genetics are questioned among population geneticists in Colombia. Although forensic technicians are aware of the disputes among population geneticists, they use and endorse the relations established between genetics, 'race' and geography because these fit with common-sense notions of visible bodily difference and the regionalization of race in the Colombian nation.

    This article examines the role that vernacular notions of racialized-regional difference play in the constitution and stabilization of DNA populations in Colombian forensic science, in what we frame as a process of public science. In public science, the imaginations of the scientific world and common-sense public knowledge are integral to the production and circulation of science itself. We explore the origins and circulation of a scientific object – ‘La Tabla’, published in Paredes et al. and used in genetic forensic identification procedures – among genetic research institutes, forensic genetics laboratories and courtrooms in Bogotá. We unveil the double life of this central object of forensic genetics. On the one hand, La Tabla enjoys an indisputable public place in the processing of forensic genetic evidence in Colombia (paternity cases, identification of bodies, etc.). On the other hand, the relations it establishes between ‘race’, geography and genetics are questioned among population geneticists in Colombia. Although forensic technicians are aware of the disputes among population geneticists, they use and endorse the relations established between genetics, ‘race’ and geography because these fit with common-sense notions of visible bodily difference and the regionalization of race in the Colombian nation.

    Education in developing countries still has a long way to go before it equals what those of us in developed countries take for granted. In India, for example, there are between 300 and 500 million people for whom education is virtually non-existent. Rajan Gupta, a physicist at the US Los Alamos National Laboratory (LANL), devotes part of his time to giving lectures in Indian schools mainly about HIV/AIDS, but also about other societal issues. In his Science and Society talk at CERN, Gupta will talk about education in India, focusing on key issues at school, college, and university level. Gupta will highlight the need to provide the combination of health care, nutrition and education, and he will present plans for introducing the use of computers and modern communication systems to educate children. Issues of migration and brain drain, as well as overall global threats to human security will also be discussed. Rajan Gupta, leader of the 'elementary particles and field theory' group at LANL, started promoting...

    We applied a wide-field time-resolved luminescence (TRL) method with a pulsed laser and a gated intensified charge coupled device (ICCD) for deciphering obliterated documents for use in forensic science. The TRL method can nondestructively measure the dynamics of luminescence, including fluorescence and phosphorescence lifetimes, which prove to be useful parameters for image detection. First, we measured the TRL spectra of four brands of black porous-tip pen inks on paper to estimate their luminescence lifetimes. Next, we acquired the TRL images of 12 obliterated documents at various delay times and gate times of the ICCD. The obliterated contents were revealed in the TRL images because of the difference in the luminescence lifetimes of the inks. This method requires no pretreatment, is nondestructive, and has the advantage of wide-field imaging, which makes it is easy to control the gate timing. This demonstration proves that TRL imaging and spectroscopy are powerful tools for forensic document examination.

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available The famous gulf between the arts and the sciences comes from the current pervasiveness of scientific illiteracy. The resultant increased fragmentation of science threatens scientific research; the resultant increase of the portion of the population of the advanced world that shows general ignorance of science threatens Western culture and democracy, and thus science itself. Historians and popularizers of science can help reduce this gulf. Introducing science historically can help solve many acute social and political problems. Historians of science can try to bring this about. Discussions of the social role of intellectuals (and of historians of science in particular require a great deal of a sense of proportion, since most people are still barely educated, hardly familiar with science, much less with its history. Science nonetheless influences lives. Current increased inaccessibility of science boosts the prevailing excessive scientific specialization that scientific and technological progress have imposed. Consequently, the search diminishes severely for comprehensive overviews of the world and even of specific parts of it, leading to disorientation that imperils even the normal functioning of science. There is then a vital need for a search for remedy. Philosophers and historians and popularizers of science can help develop the tools necessary for this vital search.

  18. Metagenomic analyses of bacteria on human hairs: a qualitative assessment for applications in forensic science.

    Mammalian hairs are one of the most ubiquitous types of trace evidence collected in the course of forensic investigations. However, hairs that are naturally shed or that lack roots are problematic substrates for DNA profiling; these hair types often contain insufficient nuclear DNA to yield short tandem repeat (STR) profiles. Whilst there have been a number of initial investigations evaluating the value of metagenomics analyses for forensic applications (e.g. examination of computer keyboards), there have been no metagenomic evaluations of human hairs-a substrate commonly encountered during forensic practice. This present study attempts to address this forensic capability gap, by conducting a qualitative assessment into the applicability of metagenomic analyses of human scalp and pubic hair. Forty-two DNA extracts obtained from human scalp and pubic hairs generated a total of 79,766 reads, yielding 39,814 reads post control and abundance filtering. The results revealed the presence of unique combinations of microbial taxa that can enable discrimination between individuals and signature taxa indigenous to female pubic hairs. Microbial data from a single co-habiting couple added an extra dimension to the study by suggesting that metagenomic analyses might be of evidentiary value in sexual assault cases when other associative evidence is not present. Of all the data generated in this study, the next-generation sequencing (NGS) data generated from pubic hair held the most potential for forensic applications. Metagenomic analyses of human hairs may provide independent data to augment other forensic results and possibly provide association between victims of sexual assault and offender when other associative evidence is absent. Based on results garnered in the present study, we believe that with further development, bacterial profiling of hair will become a valuable addition to the forensic toolkit.

For 60 years, the Member States have not only invested considerable financial means into this institution, but have also supported the creation of a highly visionary research programme. And this has led to a change in the way science is done, as captured by the idea of "big science". Yet this naturally also raises a number of quite fundamental questions: How did the meaning of "doing science" change? What justifies societal engagement with and support for such a cost-intensive long-term scientific undertaking? And finally, in what ways does (and did) this research enterprise contribute to the development of contemporary societies? By focusing on some key examples, the talk will thus explore how the ways of doing research and scientific and societal relations have undergone change over the ...

    Statement of the problem. As future citizens, students will have the enormous responsibility of making decisions that will require an understanding of the interaction of science and technology and its interface with society. Since many societal issues today are grounded in science and technology, learning science in its social context is vital to science education reform. Science-Technology-Society (STS) has been strongly identified with meeting this goal, but despite its benefits, putting theory into practice has been difficult. Research design and methodology. The purpose of this study was to explore teacher beliefs about teaching science through STS. The following broad research questions guided the study: (1) What are the participants' initial beliefs about teaching science through STS? (2) What beliefs emerge as participants reflect upon and share their STS instructional experiences with their peers? A social constructivist theoretical framework was developed to plan interactions and collect data. Within this framework, a qualitative methodology was used to interpret the data and answer the research questions. Three provisionally certified science teachers engaged in a series of qualitative tasks including a written essay, verbal STS unit explanation, reflective journal writings, and focus group interviews. After implementing their STS unit, the participants engaged in meaningful dialogue with their peers as they reflected upon, shared, and constructed their beliefs. Conclusions. The participants strongly believed in STS as a means for achieving scientific and technological literacy, developing cognition, enhancing scientific habits of mind and affective qualities, and fostering citizen responsibility. Four major assertions were drawn: (a) Participants' initial belief in teaching for citizen responsibility did not fully align with practice, (b) Educators at the administrative level should be made aware of the benefits of teaching science through STS, (c

    Interpreting mixed DNA samples containing material from multiple contributors has long been considered a major challenge in forensic casework, especially when encountering low-template DNA (LT-DNA) or high-order mixtures that may involve missing alleles (dropout) and unrelated alleles (drop-in), among others. In the last decades, extraordinary progress has been made in the analysis of mixed DNA samples, which has led to increasing attention to this research field. The advent of new methods for the separation and extraction of DNA from mixtures, novel or jointly applied genetic markers for detection and reliable interpretation approaches for estimating the weight of evidence, as well as the powerful massively parallel sequencing (MPS) technology, has greatly extended the range of mixed samples that can be correctly analyzed. Here, we summarized the investigative approaches and progress in the field of forensic DNA mixture analysis, hoping to provide some assistance to forensic practitioners and to promote further development involving this issue.

    2013-09-25

    The American Indian Science and Engineering Society (AISES) has been funded under a U.S. Department of Energy (DOE) grant (Grant Award No. DE-SC0004058) to host an Intertribal Middle-School Science and Math Bowl (IMSSMB) comprised of teams made up of a majority of American Indian students from Bureau of Indian Education-funded schools and public schools. The intent of the AISES middle school science and math bowl is to increase participation of American Indian students at the DOE-sponsored National Science Bowl. Although national in its recruitment scope, the AISES Intertribal Science and Math Bowl is considered a “regional” science bowl, equivalent to the other 50 regional science bowls which are geographically limited to states. Most regional bowls do not have American Indian student teams competing, hence the AISES bowl is meant to encourage American Indian student teams to increase their science knowledge in order to participate at the national level. The AISES competition brings together teams from various American Indian communities across the nation. Each team is provided with funds for travel to and from the event, as well as for lodging and meals. In 2011 and 2012, there were 10 teams participating; in 2013, the number of teams participating doubled to 20. Each Science and Math Bowl team is comprised of four middle school — grades 6 through 8 — students, one alternate, and a teacher who serves as advisor and coach — although in at least two cases, the coach was not a teacher, but was the Indian Education Coordinator. Each team member must have at least a 3.0 GPA. Furthermore, the majority of students in each team must be comprised of American Indian, Alaska Native or Native Hawaiian students. Under the current DOE grant, AISES sponsored three annual middle school science bowl competitions over the years 2011, 2012 and 2013. The science and math bowls have been held in late March concurrently with the National American Indian Science and

    2001-01-01

    Full text: Nuclear Forensic Science is a new branch of forensic science, which has arisen out of necessity following the dissolution of the former Soviet Union and East Block countries. One result of this break up was the emergence of a new form of smuggling, involving nuclear materials, radioactive sources and scrap metal contaminated with radioactive substances. Since 1994 the Institute for Transuranium Elements of the European Commission Joint Research Centre has played a major role in combating the illicit trafficking in nuclear materials and contaminated scrap metals. The Institute has the advantages of extensive experience in handling these materials, which require sophisticated instruments mounted in glove boxes. As part of the European Commission Joint Research Centre the Institute is also independent of national interests within the European Union and abroad. Some twenty-five cases of illicit trafficking have been examined so far. Some of the latest cases will be described and the methods developed at the Institute for isotopic and microstructural fingerprinting of nuclear materials will be illustrated. The microstructural fingerprint is a new technique developed here, which complements the isotopic analysis of the samples, and is highly characteristic of the production process and subsequent history of the materials involved. Furthermore, the microstructural fingerprint cannot be disguised by, for example, the addition of other substances or isotopes to the sample. An extensive database on commercial nuclear materials is maintained by the Institute, and this is being enlarged to include microstructural information such as porosity, grain size, precipitation, dislocation structures, pellet surface roughness, etc. The database can be used for comparison when samples of unknown provenance are seized. The Institute places emphasis on developing close co-operation with the legal authorities to optimize the side-by-side working of law enforcement officers and

  10. The effect of science-technology-society issue instruction on the attitudes of female middle school students toward science

    Science.gov (United States)

    Mullinnix, Debra Lynn

    An assessment of the science education programs of the last thirty years reveals traditional science courses are producing student who have negative attitudes toward science, do not compete successfully in international science and mathematics competitions, are not scientifically literate, and are not interested in pursuing higher-level science courses. When the number of intellectually-capable females that fall into this group is considered, the picture is very disturbing. Berryman (1983) and Kahle (1985) have suggested the importance of attitude both, in terms of achievement in science and intention to pursue high-level science courses. Studies of attitudes toward science reveal that the decline in attitudes during grades four through eight was much more dramatic for females than for males. There exists a need, therefore, to explore alternative methods of teaching science, particularly in the middle school, that would increase scientific literacy, improve attitudes toward science, and encourage participation in higher-level science courses of female students. Yager (1996) has suggested that science-technology-society (STS) issue instruction does make significant changes in students' attitudes toward science, stimulates growth in science process skills, and increases concept mastery. The purpose of this study was to examine the effect STS issue instruction had on the attitudes of female middle school students toward science in comparison to female middle school students who experience traditional science instruction. Another purpose was to examine the effect science-technology-society issue instruction had on the attitudes of female middle school students in comparison to male middle school students. The pretests and the posttests were analyzed to examine differences in ten domains: enjoyment of science class; usefulness of information learned in science class; usefulness of science skills; feelings about science class in general; attitudes about what took place

  11. Forensic archaeology and anthropology : An Australian perspective.

    Science.gov (United States)

    Oakley, Kate

    2005-09-01

    Forensic archaeology is an extremely powerful investigative discipline and, in combination with forensic anthropology, can provide a wealth of evidentiary information to police investigators and the forensic community. The re-emergence of forensic archaeology and anthropology within Australia relies on its diversification and cooperation with established forensic medical organizations, law enforcement forensic service divisions, and national forensic boards. This presents a unique opportunity to develop a new multidisciplinary approach to forensic archaeology/anthropology within Australia as we hold a unique set of environmental, social, and cultural conditions that diverge from overseas models and require different methodological approaches. In the current world political climate, more forensic techniques are being applied at scenes of mass disasters, genocide, and terrorism. This provides Australian forensic archaeology/anthropology with a unique opportunity to develop multidisciplinary models with contributions from psychological profiling, ballistics, sociopolitics, cultural anthropology, mortuary technicians, post-blast analysis, fire analysis, and other disciplines from the world of forensic science.

    Modern science has changed every aspect of life in ways that cannot be compared to developments of previous eras. This four volume set presents key developments within modern physical science and the effects of these discoveries on modern global life. The first two volumes explore the history of the concept of relativity, the cultural roots of science, the concept of time and gravity before, during, and after Einstein's theory, and the cultural reception of relativity. Volume three explores the impact of modern science upon global politics and the creation of a new kind of war, and Volume four details the old and new efforts surrounding the elucidation of the quantum world, as well as the cultural impact of particle physics. The collection also presents the historical and cultural context that made these scientific innovations possible. The transformation of everyday concepts of time and space for the individual and for society, the conduct of warfare, and the modern sense of mastering nature are all issues d...

    2008-03-01

    Full Text Available To give a good public speech is art; but definitely more difficult is to organize a productive exchange of points of views between scientists, experts, non-experts and policy-makers on controversial issues such as a scenario workshop or a consensus conference. Many skills and a deep knowledge both of the topic and of the methodology are required. But this is the future of science communication, a field where the dialogical model will impose new and complex formats of communication and a new sensibility, using also the most traditional media. But are science communicators prepared for that? What is the state of the art of science communicator training?

    Many advances in health care fail to reach patients. Implementation science is the study of novel approaches to mitigate this evidence-to-practice gap. The American Thoracic Society (ATS) created a multidisciplinary ad hoc committee to develop a research statement on implementation science in pulmonary, critical care, and sleep medicine. The committee used an iterative consensus process to define implementation science and review the use of conceptual frameworks to guide implementation science for the pulmonary, critical care, and sleep community and to explore how professional medical societies such as the ATS can promote implementation science. The committee defined implementation science as the study of the mechanisms by which effective health care interventions are either adopted or not adopted in clinical and community settings. The committee also distinguished implementation science from the act of implementation. Ideally, implementation science should include early and continuous stakeholder involvement and the use of conceptual frameworks (i.e., models to systematize the conduct of studies and standardize the communication of findings). Multiple conceptual frameworks are available, and we suggest the selection of one or more frameworks on the basis of the specific research question and setting. Professional medical societies such as the ATS can have an important role in promoting implementation science. Recommendations for professional societies to consider include: unifying implementation science activities through a single organizational structure, linking front-line clinicians with implementation scientists, seeking collaborations to prioritize and conduct implementation science studies, supporting implementation science projects through funding opportunities, working with research funding bodies to set the research agenda in the field, collaborating with external bodies responsible for health care delivery, disseminating results of implementation

  2. Virtual tool mark generation for efficient striation analysis in forensic science

    Energy Technology Data Exchange (ETDEWEB)

    Ekstrand, Laura [Iowa State Univ., Ames, IA (United States)

    2012-01-01

    In 2009, a National Academy of Sciences report called for investigation into the scienti c basis behind tool mark comparisons (National Academy of Sciences, 2009). Answering this call, Chumbley et al. (2010) attempted to prove or disprove the hypothesis that tool marks are unique to a single tool. They developed a statistical algorithm that could, in most cases, discern matching and non-matching tool marks made at di erent angles by sequentially numbered screwdriver tips. Moreover, in the cases where the algorithm misinterpreted a pair of marks, an experienced forensics examiner could discern the correct outcome. While this research served to con rm the basic assumptions behind tool mark analysis, it also suggested that statistical analysis software could help to reduce the examiner's workload. This led to a new tool mark analysis approach, introduced in this thesis, that relies on 3D scans of screwdriver tip and marked plate surfaces at the micrometer scale from an optical microscope. These scans are carefully cleaned to remove noise from the data acquisition process and assigned a coordinate system that mathematically de nes angles and twists in a natural way. The marking process is then simulated by using a 3D graphics software package to impart rotations to the tip and take the projection of the tip's geometry in the direction of tool travel. The edge of this projection, retrieved from the 3D graphics software, becomes a virtual tool mark. Using this method, virtual marks are made at increments of 5 and compared to a scan of the evidence mark. The previously developed statistical package from Chumbley et al. (2010) performs the comparison, comparing the similarity of the geometry of both marks to the similarity that would occur due to random chance. The resulting statistical measure of the likelihood of the match informs the examiner of the angle of the best matching virtual mark, allowing the examiner to focus his/her mark analysis on a smaller range of angles

    2017-05-01

    Emerging interdisciplinary science efforts are providing new understanding of the interdependence of food, energy, and water (FEW) systems. These science advances, in turn, provide critical information for coordinated management to improve the affordability, reliability, and environmental sustainability of FEW systems. Here we describe the current state of the FEW nexus and approaches to managing resource conflicts through reducing demand and increasing supplies, storage, and transport. Despite significant advances within the past decade, there are still many challenges for the scientific community. Key challenges are the need for interdisciplinary science related to the FEW nexus; ground-based monitoring and modeling at local-to-regional scales; incorporating human and institutional behavior in models; partnerships among universities, industry, and government to develop policy relevant data; and systems modeling to evaluate trade-offs associated with FEW decisions.

    Lecture in English, with simultaneous interpreting into French CERN is often referred to as the place “where the web was born”. The world-wide-web has fundamentally changed society and launched a wave of new global industries. The world-wide-web happened because there was a specific problem that was seen as an Information Technology (IT) challenge by its inventors. As the scientific programme of CERN has progressed, new IT challenges have been faced such as how to handle the mind-boggling amount of data that is produced by the Large Hadron Collider (LHC). Being able to face those challenges has contributed to the success of the LHC and the discovery of the Higgs particle. This public lecture will explore some of those challenges, how they have been tackled and what impact they are having beyond physics and ultimately on society as a whole. ------ Conférence en anglais – traduction simultanée en français On parle souvent du CERN comme le « berceau du web ».

  5. Bridging the gap: from biometrics to forensics.

    Jain, Anil K; Ross, Arun

    2015-08-05

    Biometric recognition, or simply biometrics, refers to automated recognition of individuals based on their behavioural and biological characteristics. The success of fingerprints in forensic science and law enforcement applications, coupled with growing concerns related to border control, financial fraud and cyber security, has generated a huge interest in using fingerprints, as well as other biological traits, for automated person recognition. It is, therefore, not surprising to see biometrics permeating various segments of our society. Applications include smartphone security, mobile payment, border crossing, national civil registry and access to restricted facilities. Despite these successful deployments in various fields, there are several existing challenges and new opportunities for person recognition using biometrics. In particular, when biometric data is acquired in an unconstrained environment or if the subject is uncooperative, the quality of the ensuing biometric data may not be amenable for automated person recognition. This is particularly true in crime-scene investigations, where the biological evidence gleaned from a scene may be of poor quality. In this article, we first discuss how biometrics evolved from forensic science and how its focus is shifting back to its origin in order to address some challenging problems. Next, we enumerate the similarities and differences between biometrics and forensics. We then present some applications where the principles of biometrics are being successfully leveraged into forensics in order to solve critical problems in the law enforcement domain. Finally, we discuss new collaborative opportunities for researchers in biometrics and forensics, in order to address hitherto unsolved problems that can benefit society at large. © 2015 The Author(s) Published by the Royal Society.

  6. The use of mitochondrial DNA (mtDNA-investigations in Forensic Sciences

    Directory of Open Access Journals (Sweden)

    S. Dawson

    1996-07-01

    Full Text Available A variety of methods was developed to characterize mtDNA. The initial aim of these techniques was to try and link diseases with specific mitochondrial defects. As a result of the maternal inheritance trait of mtDNA these techniques facilitate studies of the phylogenetic history and population structure of the human population. It has been shown that mitochondrial DNA typing can be of great value for human identification in forensic cases. The identification of victims of mass-disasters or mass-murders, where human remains can be recovered only after many years have passed, is one of the most challenging fields of forensic identification. By using automated DNA sequencing with fluorescent labels, mitochondrial DNA sequences can be generated rapidly and accurately. Computer software facilitates the rapid comparison of individual and reference sequences.

    2016-06-01

    Source identification of human biological materials in crime scene plays an important role in reconstructing the crime process. Searching specific genetic markers to identify the source of different human biological materials is the emphasis and difficulty of the research work of legal medical experts in recent years. This paper reviews the genetic markers which are used for identifying the source of human biological materials and studied widely, such as DNA methylation, mRNA, microRNA, microflora and protein, etc. By comparing the principles and methods of source identification of human biological materials using different kinds of genetic markers, different source of human biological material owns suitable marker types and can be identified by detecting single genetic marker or combined multiple genetic markers. Though there is no uniform standard and method for identifying the source of human biological materials in forensic laboratories at present, the research and development of a series of mature and reliable methods for distinguishing different human biological materials play the role as forensic evidence which will be the future development direction.

    To explore the application value and forensic significance of ischemia modified albumin (IMA) in pericardial fluid to diagnose sudden cardiac death. IMA level in pericardial fluid was detected in acute ischemic heart disease group ( n =36), acute myocardial infarction group ( n =6), cardiomyopathy group ( n =4) and control group ( n =15) by albumin cobalt binding method. The levels of IMA were compared among these groups. The best cut-off IMA value was estimated and the sensitivity and specificity of acute myocardial ischemia group was distinguished from control group by receiver operating characteristics (ROC) curve. The IMA level in acute ischemic heart disease group was significantly higher than that of control group ( P 0.05). The cut-off value for the identification of acute myocardial ischemia which obtained by ROC analysis was 40.65 U/mL. And the sensitivity and specificity for distinguishing acute ischemia cardiac disease was 60.0% and 80.5%, respectively. The IMA value in pericardial fluid can be a reference marker for the diagnosis of acute myocardial ischemia, which also can provide objective basis for the forensic identification of sudden cardiac death.

  9. Assessing the quantified impact of a hybrid POGIL methodology on student averages in a forensic science survey course

    Science.gov (United States)

    Meeks, Tyna L.

    A causal-comparative/quasi experimental study examined the effect of incorporating a hybrid teaching methodology that blended lecture with Process Oriented Guided Inquiry Lessons (POGILs) on the overall academic achievement of a diverse student body in a large lecture setting. Additional considerations included student gender, ethnicity, declared major (STEM or non-STEM), and SAT scores. An evaluation of the effect that these characteristics had on student achievement due to differentiating import placed on the use of POGILs as a learning tool was included. This study used data obtained from a longitudinal examination of eight years of student data from an introductory forensic science survey course offered in a R1 northeastern university. This study addressed the effectiveness of applying a proscribed active learning methodology, one proposed effective in collegiate education, to a new environment, forensic science. The methodology employed combined fourteen POGILs, created specifically for the chosen course, with didactic lecture during the entire semester of a forensic science survey course. This quasi-experimental design used the manipulation of the independent variable, the use of a hybrid lecture instead of exclusive use of traditional didactic lectures, on the students' academic achievement on exams given during the course. Participants in this study (N=1436) were undergraduate students enrolled in the single semester introductory science course. A longitudinal study that incorporated eight years of data was completed, 4 years pre-intervention (2007-2010) and 4 years post-intervention (2011-2014). The forensic science survey course, taught by only one professor during the eight-year period, was a science discipline that had yet to integrate an active learning educational model. Findings indicate four variables significantly contributed to explaining nearly 28% of the variation seen in the student class averages earned during the eight-year period: the

  10. A bridge between conceptual frameworks sciences, society and technology studies

    CERN Document Server

    2015-01-01

    This book analyzes scientific problems within the history of physics, engineering, chemistry, astronomy and medicine, correlated with technological applications in the social context. When and how is tension between disciplines explicitly practised? What is the conceptual bridge between science researches and the organization of technological researches in the development of  industrial applications?  The authors explain various ways in which the sciences allowed advanced modelling on the one hand, and the development of new technological ideas on the other hand. An emphasis on the role played by mechanisms, production methods and instruments bestows a benefit on historical and scientific discourse: theories, institutions, universities, schools for engineers, social implications as well.  Scholars from different traditions discuss the emerging style of thinking in methodology and, in theoretical perspective, aim to gather and re-evaluate the current thinking on this subject. It brings together contribution...

  14. Development of an Analysis Model from the Perspectives of Science, Individual and Society in the Teaching of Science

    Directory of Open Access Journals (Sweden)

    José Manuel do Carmo

    2016-12-01

    Full Text Available The basic vision of learning science has changed as scientific culture concepts evolution and the nature of the teaching of science go along. From a model essentially based on information acquisition, science instruction has included the practice of the science method when the importance of emphasizing the development of personal skills, thinking processes, and action was considered. The concern about citizens’ education in matters referring to the relationship between science and society and enlightened social participation demanded a special attention in investigation and in students’ participation in issues related to urban, natural, and technological environment. This research seeks to develop an integrative model of curriculum organizations based on these three axes or perspectives: science, individual, and society. A matrix enabling the analysis of curricular proposals and organization plans of didactic units is built, as well as the observation of teachers’ representations in the teaching of science.

  15. Forensic Mass Spectrometry

    Science.gov (United States)

    Hoffmann, William D.; Jackson, Glen P.

    2015-07-01

    Developments in forensic mass spectrometry tend to follow, rather than lead, the developments in other disciplines. Examples of techniques having forensic potential born independently of forensic applications include ambient ionization, imaging mass spectrometry, isotope ratio mass spectrometry, portable mass spectrometers, and hyphenated chromatography-mass spectrometry instruments, to name a few. Forensic science has the potential to benefit enormously from developments that are funded by other means, if only the infrastructure and personnel existed to adopt, validate, and implement the new technologies into casework. Perhaps one unique area in which forensic science is at the cutting edge is in the area of chemometrics and the determination of likelihood ratios for the evaluation of the weight of evidence. Such statistical techniques have been developed most extensively for ignitable-liquid residue analyses and isotope ratio analysis. This review attempts to capture the trends, motivating forces, and likely impact of developing areas of forensic mass spectrometry, with the caveat that none of this research is likely to have any real impact in the forensic community unless: (a) The instruments developed are turned into robust black boxes with red and green lights for positives and negatives, respectively, or (b) there are PhD graduates in the workforce who can help adopt these sophisticated techniques.

    2017-12-01

    Societal activities, actions, and practices affect the carbon cycle and the climate of North America in complex ways. Carbon is a key component for the functioning of croplands, grasslands, forests. Carbon fuels our industry, transportation (vehicles and roadways), buildings, and other structures. Drawing on results from the SOCCR-2, this presentation uses a social science perspective to address three scientific questions. How do human actions and activities affect the carbon cycle? How human systems such as cities, agricultural field and forests are affected by changes in the carbon cycle? How is carbon management enabled and constraint by socio-political dynamics?

    2012-04-01

    From its official founding on November 18, 1936 to the present day, the Soil Science Society of America (SSSA) has developed a rich and diverse history. SSSA began with 190 members grouped into six sections: 1) physics, 2) chemistry, 3) microbiology, 4) fertility, 5) morphology, and 6) technology. Today SSSA has over 6,000 members who can choose from any of 11 divisions, S1 Soil Physics, S2 Soil Chemistry, S3 Soil Biology and Biochemistry, S4 Soil Fertility and Plant Nutrition, S5 Pedology, S6 Soil and Water Management and Conservation, S7 Forest, Range, and Wildland Soils, S8 Nutrient Management and Soil and Plant Analysis, S9 Soil Mineralogy, S10 Wetland Soils, and S11 Soils and Environmental Quality to represent their primary area(s) of interest. The Society has also gone from being largely agriculturally focused to an eclectic mix of individuals with interests in agriculture, the environment, earth sciences, human interactions, and other diverse areas. At its founding, SSSA sponsored one publication, the Soil Science Society of America Proceedings. Today, SSSA sponsors its descendent, the Soil Science Society of America Journal, as well as Vadose Zone Journal, the Journal of Environmental Quality, Soil Survey Horizons, and the Journal of Natural Resources and Life Science Education. In short, SSSA's history has been one of continued growth over the last 75 years. The future holds many challenges for SSSA and the field of soil science. There are increasing calls to meet with groups other than or in addition to the American Society of Agronomy and the Crop Science Society of America, groups like the Geological Society of America and the Ecological Society of America. Members in SSSA now work in university departments, government agencies, and businesses representing the fields of biology, geology, geography, and archeology, among others, in addition to the traditional agricultural sector. How SSSA handles this diversification of the field and its membership will

    This article presents a web-based educational project focused on the potential value of Information and Communication Technology to enhance communication and education on nuclear science throughout Brazil. The project is designed to provide trustworthy information about the beneficial uses of nuclear technology, educating children and teenagers, as well as their parents and teachers, demystifying paradigms and combating misinformation. Making use of a range of interactive activities, the website presents short courses and curiosities, with different themes that comprise the several aspects of the beneficial applications of nuclear science. The intention of the many interactive activities is to encourage research and to enhance learning opportunities through a self-learning universe where the target public is introduced to the basic concepts of nuclear physics, such as nuclides and isotopes, atomic interactions, radioactive decay, biological effects of radiation, nuclear fusion, nuclear fission, nuclear reactors, nuclear medicine, radioactive dating methods and natural occurring radiation, among other ideas and concepts in nuclear physics. Democratization of scientific education can inspire new thoughts, stimulate development and encourage scientific and technological researches.

  20. Science in Society: Bridging the gap to connect science to decision makers

    Science.gov (United States)

    Jones, L.; Bwarie, J.; Pearce, I.

    2016-12-01

    The gap between science and decision making in our society can be large and multi-faceted, involving communication, process, cultural and even subconscious differences. In sweeping generalization, scientists reject anecdotes, focus on uncertainty and details, and expect conflict as part of the scientific process, while non-scientists respond to stories, want certainty and the big picture, and see conflict as a reason to reject the message. Bridging this gap often requires ongoing collaboration to find the intersection of three independent domains: what science can provide, the technical information decision makers need to make the most effective choices and what information decision makers need to motivate action. For ten years, the USGS has experimented with improving the usefulness of its science through the SAFRR (Science Application for Risk Reduction) Project and its predecessor, the Multi Hazards Demonstration Project in Southern California. Through leading and participating in these activities, we have recognized 3 steps that have been essential to successful partnerships between scientists and decision makers. First, determining what makes for a successful product cannot be done in isolation by either scientists or users. The users may want something science cannot produce (e.g., accurate short-term earthquake predictions), while the scientists can fail to see that the product they know how to make may not be relevant to the decisions that need to be made. Real discussions with real exchange and absorption of information on both sides makes for the most useful products. Second, most scientific results need work beyond what belongs in a journal to create a product that can be used. This is not just a different style of communication, but analyses that focus on the community's local questions rather than on scientific advances. Third, probabilities of natural hazards almost never motivate action to mitigate. The probabilities are usually low on human time

    Since the first demonstration of the laser in 1960 by Theodore Maiman at Hughes Research Laboratories, the principal defining characteristic of lasers has been their ability to focus unprecedented powers of light in space, time, and frequency. High-power lasers have, over the ensuing five and a half decades, illuminated entirely new fields of scientific endeavor as well as made a profound impact on society. While the United States pioneered lasers and their early applications, we have been eclipsed in the past decade by highly effective national and international networks in both Europe and Asia, which have effectively focused their energies, efforts, and resources to achieve greater scientific and societal impact. This white paper calls for strategic investment which, by striking an appropriate balance between distributing our precious national funds and establishing centers of excellence, will ensure a broad pipeline of people and transformative ideas connecting our world-leading universities, defining flagship facilities stewarded by our national laboratories, and driving innovation across industry, to fully exploit the potential of high-power lasers.

  4. Dismantling the Justice Silos: avoiding the pitfalls and reaping the benefits of information-sharing between forensic science, medicine and law.

    Forensic science is increasingly relied on by police and the courts to exonerate the innocent and to establish links to crime. With this increased reliance the potential for unjust outcomes increases, especially in serious matters for two reasons. The more serious the matter, the more likely that evidence mishandling can lead to wrongful imprisonment, and the more likely the personnel involved will be multi-disciplinary (police, medicine, law, forensic science), and multi-organisational (Health, Justice, private legal/medical, police). The importance of identifying effective multi-organisational interactions was highlighted in the recent wrongful imprisonment of an Australian male for a sexual assault he did not commit. One factor that led to this unjust outcome was the justice silo effect: where forensic practitioners from different agencies operate in isolation (rarely communicating or sharing information/knowledge). In this paper we discuss findings from the Interfaces Project designed to assess the extent of the justice silos within Australia. We interviewed 103 police, forensic scientists, lawyers, judges, coroners, pathologists and forensic physicians Australian-wide. Five main themes were identified in the data: the silo effect was only partial and in each jurisdiction some form of inter-agency communication was actively occurring; inter-agency meetings were more common in homicide than sexual assault cases; forensic physicians were semi-invisible; there had been considerable momentum over the past ten years for practice improvement groups, and; practitioners gain more benefits than pitfalls from inter-agency information-sharing. Based on these findings, five recommendations are made for improving practice. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    2017-01-01

    The scope of forensic toxicology has been tremendously expanded over the past 50 years. From two general sections forensic toxicology can be further classified into 8-9 sections. The most outstanding improvement in forensic toxicology is the changes brought by instrumental development. The field of forensic toxicology was revolutionized by the development of immunoassay and benchtop GC-MS in the 1980's and LC-MS-MS in 2000's. Detection of trace amounts of analytes has allowed the use of new specimens such as hair and oral fluids, along with blood and urine. Over a longer period of time, continuous efforts have been made to efficiently extract and separate drug and poison from biological fluids. International endeavors to develop high quality standards and guidelines for drugs and poisons in biological specimens and to promote them in order to increase reliability of laboratories are also part of the recent advancement of forensic toxicology. Interpretation of postmortem toxicology encompasses various factors including postmortem redistribution and stability. Considering the recent trend, the interpretation of toxicological results should account for autopsy findings, crime scene information, and related medical history. The fields of forensic toxicology will continuously develop to improve analysis of target analytes from various specimens, quality assurance program, and results interpretation. In addition, the development of analytical techniques will also contribute further advancement of forensic toxicology. The societies of forensic toxicologists, such as TIAFT, will play an important role for the advancement of forensic toxicology by collaborating and sharing ideas between toxicologists from both developed and developing countries.

This review aims to discuss the utility of various dental specialities with forensic odontology.

  10. Science and society: different bioethical approaches towards animal experimentation.

    Science.gov (United States)

    Brom, Frans W A

    2002-01-01

    The use of live animals for experiments plays an important role in many forms of research. This gives rise to an ethical dilemma. On the one hand, most of the animals used are sentient beings who may be harmed by the experiments. The research, on the other hand, may be vital for preventing, curing or alleviating human diseases. There is no consensus on how to tackle this dilemma. One extreme is the view taken by adherents of the so-called animal rights view. According to this view, we are never justified in harming animals for human purposes - however vital these purposes may be. The other extreme is the ruthless view, according to which animals are there to be used at our discretion. However, most people have a view situated somewhere between these two extremes. It is accepted that animals may be used for research - contrary to the animal rights view. However, contrary to the ruthless view, that is only accepted under certain conditions. The aim of this presentation is to present different ethical views which may serve as a foundation for specifying the circumstances under which it is acceptable to use animals for research. Three views serving this role are contractarianism, utilitarianism and a deontological approach. According to contractarianism, the key ethical issue is concern for the sentiments of other human beings in society, on whose co-operation those responsible for research depend. Thus it is acceptable to use animals as long as most people can see the point of the experiment and are not offended by the way it is done. According to utilitarianism, the key ethical issue is about the consequences for humans and animals. Thus it is justified to use animals for research if enough good comes out of it in terms of preventing suffering and creating happiness, and if there is no better alternative. In the deontological approach the prima facie duty of beneficence towards human beings has to be weighed against the prima facie duties not to harm animals and to

    The subsea telecommunications cable industry is approaching a prospective new era: deploying SMART subsea cable systems (SMART = Science Monitoring And Reliable Telecommunication). The current global, commercial cable infrastructure consists of 1 Gm of cable, being refreshed now and expanding in the future. The SMART concept is to add a small external sensor package along the cable system at its optical repeaters to transmit important real-time environmental data via a dedicated wavelength or overhead channel in the transmission system, avoiding any impact on the commercial traffic. These small, reliable, existing sensors would precisely measure temperature, pressure and three-axis acceleration across the world's ocean floor over an extended period of time, being deployed using standard cable-laying procedures on new or refurbished cables, but not requiring maintenance through the 2-3 decade life of the cable systems. The game-changing factor is the urgent international need for ocean environmental data related to mitigating climate and sea-level change and improving tsunami and slope failure hazard warnings. Societal costs incurred by these are reaching billions of dollars and hundreds of thousands of deaths. Pressures for new and urgent public policies are evident from the 5th IPCC Assessment, USA-China agreement on limiting greenhouse gas emissions, clear evidence for rapid global warming, 21st Session of the Conference of the Parties to the UNFCCC (December 2015, Paris), and the scale of the costs of inaction. To support revised public policies and actions, decision-makers, industry leaders, and the public are seeking key scientific data, which will necessitate new sources of funding. Hence, the emergence of new SMART cable systems offered by the subsea telecommunications industry will provide new market opportunities, engage additional non-traditional users, and make profound societal contributions.

  13. A comparative analysis of Science-Technology-Society standards in elementary, middle and high school state science curriculum frameworks

    Science.gov (United States)

    Tobias, Karen Marie

    An analysis of curriculum frameworks from the fifty states to ascertain the compliance with the National Science Education Standards for integrating Science-Technology-Society (STS) themes is reported within this dissertation. Science standards for all fifty states were analyzed to determine if the STS criteria were integrated at the elementary, middle, and high school levels of education. The analysis determined the compliance level for each state, then compared each educational level to see if the compliance was similar across the levels. Compliance is important because research shows that using STS themes in the science classroom increases the student's understanding of the concepts, increases the student's problem solving skills, increases the student's self-efficacy with respect to science, and students instructed using STS themes score well on science high stakes tests. The two hypotheses for this study are: (1) There is no significant difference in the degree of compliance to Science-Technology-Society themes (derived from National Science Education Standards) between the elementary, middle, and high school levels. (2) There is no significant difference in the degree of compliance to Science-Technology-Society themes (derived from National Science Education Standards) between the elementary, middle, and high school level when examined individually. The Analysis of Variance F ratio was used to determine the variance between and within the three educational levels. This analysis addressed hypothesis one. The Analysis of Variance results refused to reject the null hypothesis, meaning there is significant difference in the compliance to STS themes between the elementary, middle and high school educational levels. The Chi-Square test was the statistical analysis used to compare the educational levels for each individual criterion. This analysis addressed hypothesis two. The Chi-Squared results showed that none of the states were equally compliant with each

    We argue that philosophical and historical research can constitute a "Biohumanities" that deepens our understanding of biology itself engages in constructive "science criticism," helps formulate new "visions of biology," and facilitates "critical science communication." We illustrate these ideas with two recent "experimental philosophy" studies of the concept of the gene and of the concept of innateness conducted by ourselves and collaborators. We conclude that the complex and often troubled relations between science and society are critical to both parties, and argue that the philosophy and history of science can help to make this relationship work.

    The Brazilian Soil Science Society (SBCS) is one of the oldest scientific societies in Brazil. It was created in October 1947 during the 1st Brazilian Meeting of Soil Science held at the headquarters of the Agricultural Chemistry Institute of Rio de Janeiro, at present the Soils Institute of the Brazilian Agricultural Research Centre. Its origin lies within the Interamerican Conference of Agriculture, Caracas, 1945, the 2nd Pan American Congress of Mining and Geology, Petropolis, Rio de Janeiro, 1946 and the 5th Brazilian Congress of Chemistry, Porto Alegre, 1947. Its first president was Álvaro Barcelos Fagundes, who was the only Brazilian participant at the 1st International Congress of Soil Science and Transcontinental Excursion held in United States of America, in 1927. At that time he was engaged in research work at the New Jersey Agricultural Experiment Station, at the Rutgers University where he did a doctorate under the guidance of Professor Selman Waksman. The society started with 47 members and presently has nearly 900 members. In its first phase the Brazilian Soil Science Society was housed at the Agricultural Chemistry Institute in Rio de Janeiro and its main activity was the biannual Brazilian Congress of Soil Science. In 1975 its headquarters moved to the Agronomic Institute of Campinas with the creation of its executive board and the start of publication of the Brazilian Journal of Soil Science (1977) as well as the society bulletin (1976). In 1997 its executive office moved to the Soils Department at the Federal University of Viçosa. Nowadays it has a structure similar to the one from the IUSS: the society is organized in four divisions (Soil in space and time, Soils properties and processes, Soil use and management and Soil, environment and society) which encompass 14 technical commissions and eight State or Regional nuclei. The Brazilian Congresses of Soil Science happen without interruption since 1947. The first one had had 72 participants that

  16. Forensic DNA phenotyping in criminal investigations and criminal courts: assessing and mitigating the dilemmas inherent in the science.

    2014-01-01

    Forensic DNA Phenotyping ("FDP"), estimating the externally visible characteristics ("EVCs") of the source of human DNA left at a crime scene, is evolving from science fiction toward science fact. FDP can already identify a source's gender with 100% accuracy, and likely hair color, iris color, adult height, and a number of other EVCs with accuracy rates approaching 70%. Patent applications have been filed for approaches to generating 3D likenesses of DNA sources based on the DNA alone. Nonetheless, criminal investigators, particularly in the United States, have been reticent to apply FDP in their casework. The reticence is likely related to a number of perceived and real dilemmas associated with FDP: is FDP racial profiling, should we test unknown and unseen physical conditions, does testing for behavioral characteristics impermissibly violate the source's privacy, ought testing be permitted for samples from known sources or DNA databases, and should FDP be limited to use in investigations only or is FDP appropriate for use in a criminal court. As this article explains, although those dilemmas are substantive, they are not insurmountable, and can be quite easily managed with appropriate regulation and protocols. As FDP continues to develop, there will be less need for criminal investigators to shy away from FDP. Cold cases, missing persons, and victims in crimes without other evidence will one day soon all be well served by FDP.

    Compared to other sciences, computer forensics (digital forensics) is a relatively young discipline. It was established in 1999 and it has been an irreplaceable tool in sanctioning cybercrime ever since. Good knowledge of computer forensics can be really helpful in uncovering a committed crime. Not adhering to the methodology of computer forensics, however, makes the obtained evidence invalid/irrelevant and as such it cannot be used in legal proceedings.

    2017-01-02

    We explore the integration of societal issues in undergraduate training within the life sciences. Skills in thinking about science, scientific knowledge production and the place of science in society are crucial in the context of the idea of responsible research and innovation. This idea became institutionalized and it is currently well-present in the scientific agenda. Developing abilities in this regard seems particularly relevant to training in the life sciences, as new developments in this area somehow evoke the involvement of all of us citizens, our engagement to debate and take part in processes of change. The present analysis draws from the implementation of a curricular unit focused on science-society dialogue, an optional course included in the Biochemistry Degree study plan offered at the University of Porto. This curricular unit was designed to be mostly an exploratory activity for the students, enabling them to undertake in-depth study in areas/topics of their specific interest. Mapping topics from students' final papers provided a means of analysis and became a useful tool in the exploratory collaborative construction of the course. We discuss both the relevance and the opportunity of thinking and questioning the science-society dialogue. As part of undergraduate training, this pedagogical practice was deemed successful. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(1):46-52, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

    The University based Science Shops were established in the 1970s in the Netherlands, and in Denmark and other countries in the 1980s and 1990s. The aim was to give civil society organisations access to scientific knowledge and to empower citizen participation regarding environmental and social...... improvements. It has recently been suggested that the role of Science Shops should change as a consequence of the stated increasing professionalisation of the Non Governmental Organisations and Civil Society Organisations, and of industry’s increasing interest in introducing environmental management measures....... Increasing internationalisation of the environmental agenda has contributed to this as well as a general acceptance of environmental considerations in industry policy and strategy. However, with departure point in three different Science Shop projects, the article proposes that Science Shops are still...

    We present initial results from our study of how science does or does not influence the worldviews of introductory, general education college astronomy students. Our data were gathered over one course (one semester), and examine students' ideas on provocative topics such as the relationship between science and religion, comparisons between the return on investment from different government programs, the limits of scientific inquiry, and how/if science can help to solve critical problems facing our society today. Since this is the last formal science course many of these general education astronomy students will ever take, the experience they have during this course is crucial for developing an accurate and well-informed worldview that includes the role of science in society. With our research we aim to answer the question, “Can teaching help shape this worldview to incorporate science more positively?” This material is based in part upon work supported by the National Science Foundation under Grant No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS). Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation.

  2. Forensic science information needs of patrol officers: The perceptions of the patrol officers, their supervisors and administrators, detectives, and crime scene technicians

    Aydogdu, Eyup

    Thanks to the rapid developments in science and technology in recent decades, especially in the past two decades, forensic sciences have been making invaluable contributions to criminal justice systems. With scientific evaluation of physical evidence, policing has become more effective in fighting crime and criminals. On the other hand, law enforcement personnel have made mistakes during the detection, protection, collection, and evaluation of physical evidence. Law enforcement personnel, especially patrol officers, have been criticized for ignoring or overlooking physical evidence at crime scenes. This study, conducted in a large American police department, was aimed to determine the perceptions of patrol officers, their supervisors and administrators, detectives, and crime scene technicians about the forensic science needs of patrol officers. The results showed no statistically significant difference among the perceptions of the said groups. More than half of the respondents perceived that 14 out of 16 areas of knowledge were important for patrol officers to have: crime scene documentation, evidence collection, interviewing techniques, firearm evidence, latent and fingerprint evidence, blood evidence, death investigation information, DNA evidence, document evidence, electronically recorded evidence, trace evidence, biological fluid evidence, arson and explosive evidence, and impression evidence. Less than half of the respondents perceived forensic entomology and plant evidence as important for patrol officers.

    This study reported Grade 7 students' normative decision making in teaching and learning about global warming through science technology and society (STS) approach. The participants were 43 Grade 7 students in Sungkom, Nongkhai, Thailand. The teaching and learning about global warming through STS approach had carried out for 5 weeks. The global warming unit through STS approach was developed based on framework of Yuenyong (2006) that consisted of five stages including (1) identification of social issues, (2) identification of potential solutions, (3) need for knowledge, (4) decision-making, and (5) socialization stage. Students' normative decision making was collected during their learning by questionnaire, participant observation, and students' tasks. Students' normative decision making were analyzed from both pre-and post-intervention and students' ideas during the intervention. The aspects of normative include influences of global warming on technology and society; influences of values, culture, and society on global warming; and influences of technology on global warming. The findings revealed that students have chance to learn science concerning with the relationship between science, technology, and society through their giving reasons about issues related to global warming. The paper will discuss implications of these for science teaching and learning through STS in Thailand.

    The use of non-human DNA typing in forensic science investigations, and specifically that from animal DNA, is ever increasing. The term animal DNA in this document refers to animal species encountered in a forensic science examination but does not include human DNA. Non-human DNA may either be: the trade and possession of a species, or products derived from a species, which is contrary to legislation; as evidence where the crime is against a person or property; instances of animal cruelty; or where the animal is the offender. The first instance is addressed by determining the species present, and the other scenarios can often be addressed by assigning a DNA sample to a particular individual organism. Currently there is little standardization of methodologies used in the forensic analysis of animal DNA or in reporting styles. The recommendations in this document relate specifically to animal DNA that is integral to a forensic science investigation and are not relevant to the breeding of animals for commercial purposes. This DNA commission was formed out of discussions at the International Society for Forensic Genetics 23rd Congress in Buenos Aires to outline recommendations on the use of non-human DNA in a forensic science investigation. Due to the scope of non-human DNA typing that is possible, the remit of this commission is confined to animal DNA typing only. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

  5. Strengthening forensic DNA decision making through a better understanding of the influence of cognitive bias.

    2017-11-01

    Cognitive bias may influence process flows and decision making steps in forensic DNA analyses and interpretation. Currently, seven sources of bias have been identified that may affect forensic decision making with roots in human nature; environment, culture, and experience; and case specific information. Most of the literature and research on cognitive bias in forensic science has focused on patterned evidence; however, forensic DNA testing is not immune to bias, especially when subjective interpretation is involved. DNA testing can be strengthened by recognizing the existence of bias, evaluating where it influences decision making, and, when applicable, implementing practices to reduce or control its effects. Elements that may improve forensic decision making regarding bias include cognitively informed education and training, quality assurance procedures, review processes, analysis and interpretation, and context management of irrelevant information. Although bias exists, reliable results often can be (and have been) produced. However, at times bias can (and has) impacted the interpretation of DNA results negatively. Therefore, being aware of the dangers of bias and implementing measures to control its potential impact should be considered. Measures and procedures that handicap the workings of the crime laboratory or add little value to improving the operation are not advocated, but simple yet effective measures are suggested. This article is meant to raise awareness of cognitive bias contamination in forensic DNA testing and to give laboratories possible pathways to make sound decisions to address its influences.

    This volume of the Journal of Physics: Conference Series contains papers presented at the Tunisia-Japan Symposium: R&D of Energy and Material Sciences for Sustainable Society (TJS 2014) held at Gammarth, Republic of Tunisia on November 28-30, 2014. The TJS 2014 is based on the network of the Tunisia-Japan Symposium on Science, Society and Technology (TJASSST) which has been regularly organized since 2000. The symposium was focused on the technological developments of energy and materials for the realization of sustainable society. To generate technological breakthrough and innovation, it seems to be effective to discuss with various fields of researchers such as solid-state physicists, chemists, surface scientists, process engineers and so on. In this symposium, there were as many as 109 attendees from a wide variety of research fields. The technical session consisted of 106 contributed presentations including 3 plenary talks and 7 key-note talks. We hope the Conference Series and publications like this volume will contribute to the progress in research and development in the field of energy and material sciences for sustainable society and in its turn contribute to the creation of cultural life and peaceful society.

  8. Age estimation in forensic sciences: application of combined aspartic acid racemization and radiocarbon analysis.

    Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster because the age at death, birth date, and year of death as well as gender can guide investigators to the correct identity among a large number of possible matches. Traditional morphological methods used by anthropologists to determine age are often imprecise, whereas chemical analysis of tooth dentin, such as aspartic acid racemization, has shown reproducible and more precise results. In this study, we analyzed teeth from Swedish individuals using both aspartic acid racemization and radiocarbon methodologies. The rationale behind using radiocarbon analysis is that aboveground testing of nuclear weapons during the cold war (1955-1963) caused an extreme increase in global levels of carbon-14 ((14)C), which has been carefully recorded over time. Forty-four teeth from 41 individuals were analyzed using aspartic acid racemization analysis of tooth crown dentin or radiocarbon analysis of enamel, and 10 of these were split and subjected to both radiocarbon and racemization analysis. Combined analysis showed that the two methods correlated well (R(2) = 0.66, p Aspartic acid racemization also showed a good precision with an overall absolute error of 5.4 +/- 4.2 years. Whereas radiocarbon analysis gives an estimated year of birth, racemization analysis indicates the chronological age of the individual at the time of death. We show how these methods in combination can also assist in the estimation of date of death of an unidentified victim. This strategy can be of significant assistance in forensic casework involving dead victim identification.

    Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster, since the age at death, birth date and year of death, as well as gender, can guide investigators to the correct identity among a large number of possible matches. Traditional morphological methods used by anthropologists to determine age are often imprecise, whereas chemical analysis of tooth dentin, such as aspartic acid racemization has shown reproducible and more precise results. In this paper we analyze teeth from Swedish individuals using both aspartic acid racemization and radiocarbon methodologies. The rationale behind using radiocarbon analysis is that above-ground testing of nuclear weapons during the cold war (1955-1963) caused an extreme increase in global levels of carbon-14 ({sup 14}C) which have been carefully recorded over time. Forty-four teeth from 41 individuals were analyzed using aspartic acid racemization analysis of tooth crown dentin or radiocarbon analysis of enamel and ten of these were split and subjected to both radiocarbon and racemization analysis. Combined analysis showed that the two methods correlated well (R2=0.66, p < 0.05). Radiocarbon analysis showed an excellent precision with an overall absolute error of 0.6 {+-} 04 years. Aspartic acid racemization also showed a good precision with an overall absolute error of 5.4 {+-} 4.2 years. Whereas radiocarbon analysis gives an estimated year of birth, racemization analysis indicates the chronological age of the individual at the time of death. We show how these methods in combination can also assist in the estimation of date of death of an unidentified victim. This strategy can be of significant assistance in forensic casework involving dead victim identification.

    2008-04-01

    This report was produced by a Working Group of the American Physical Society's Program on Public Affairs in conjunction with the American Association for the Advancement of Science Center for Science, Technology and Security Policy. The primary purpose of this report is to provide the Congress, U.S. government agencies and other institutions involved in nuclear forensics with a clear unclassified statement of the state of the art of nuclear forensics; an assessment of its potential for preventing and identifying unattributed nuclear attacks; and identification of the policies, resources and human talent to fulfill that potential. In the course of its work, the Working Group observed that nuclear forensics was an essential part of the overall nuclear attribution process, which aims at identifying the origin of unidentified nuclear weapon material and, in the event, an unidentified nuclear explosion. A credible nuclear attribution capability and in particular nuclear forensics capability could deter essential participants in the chain of actors needed to smuggle nuclear weapon material or carry out a nuclear terrorist act and could also encourage states to better secure such materials and weapons. The Working Group also noted that nuclear forensics result would take some time to obtain and that neither internal coordination, nor international arrangements, nor the state of qualified personnel and needed equipment were currently enough to minimize the time needed to reach reliable results in an emergency such as would be caused by a nuclear detonation or the intercept of a weapon-size quantity of material. The Working Group assesses international cooperation to be crucial for forensics to work, since the material would likely come from inadequately documented foreign sources. In addition, international participation, if properly managed, could enhance the credibility of the deterrent effect of attribution. Finally the Working Group notes that the U.S. forensics

    Modern soil science was introduced just after the reformation of Japan in 1867 by Max Fesca, Oskar Kellner and other German teachers together with their Japanese students, who were traced back to Justus von Liebig and thus started studying and teaching soils based on agrogeology and agricultural chemistry. After the German teachers left, the graduates from agricultural colleges formed the Foundation of Agricultural Sciences in 1887, based on which the Society of the Science of Soil and Manure, Japan, was established in 1927. The research, education and extension activities then expanded to Korea, Manchuria and Inner Mongolia as well as Taiwan and Sakhalin in accordance with a military invasion to China and Southeast Asian countries until the end of WWII. After WWII together with the reformation guided by the General Headquarters (GHQ) of the Allied Forces, soils research and educational units increased in number in the universities and governmental institutions. The society started publication of the journal in English, "Soils and Plant Food" in 1955, which was renamed to "Soil Science and Plant Nutrition (SSPN)" in 1961. There formed a variety of discussion groups in the society such as soil microbiology, pedology, clay science, soil physics, plant physiology, and forest environment, which became independent in the 1960s. Economic growth of Japan in the 1970s accomplished self-sufficiency in rice production and extended the range of crop to grow, however, a variety of environmental issues came out. A new division was established in the society for solving soil-related environmental problems. The society became more involved in international activities and hosted a number of international conferences, workshops, etc., the most significant of which was the 14th International Congress of Soil Science at Kyoto in 1990. The society proposed there a regional organization to cope with the unique issues, e.g. improvement of paddy rice cultivation, for Asian countries and

    Researchers handle increasingly higher dimensional datasets, with many variables to explore. Such datasets pose several problems, since they are difficult to handle and present unexpected features. As dimensionality increases, classical statistical analysis becomes inoperative. Variables can present redundancy, and the reduction of dataset dimensionality to its lowest possible value is often needed. Principal components analysis (PCA) has proven useful to reduce dimensionality but present several shortcomings. As others, forensic sciences will face the issues specific related to an evergrowing quantity of data to be integrated. Age estimation in living persons, an unsolved problem so far, could benefit from the integration of various sources of data, e.g., clinical, dental and radiological data. We present here novel multivariate techniques (nonlinear dimensionality reduction techniques, NLDR), applied to a theoretical example. Results were compared to those of PCA. NLDR techniques were then applied to clinical, dental and radiological data (13 variables) used for age estimation. The correlation dimension of these data was estimated. NLDR techniques outperformed PCA results. They showed that two living persons sharing similar characteristics may present rather different estimated ages. Moreover, data presented a very high informational redundancy, i.e., a correlation dimension of 2. NLDR techniques should be used with or preferred to PCA techniques to analyze complex and big data. Data routinely used for age estimation may not be considered suitable for this purpose. How integrating other data or approaches could improve age estimation in living persons is still uncertain.

    Many think that communicating science is a necessary and rewarding activity. Yet finding compelling, relevant, and timely points of linkage between challenging scientific concepts and the experiences and interests of the general public can be difficult. Since science continues to influence more and more aspects of daily life and knowledge, there is a parallel need for communication about science in our society. Here I discuss the "middle-ground hypothesis" using popular culture for science communication and applying the "FUNnel model," where popular culture is used as a lead-in and wrap-up when discussing science. The scientific knowledge we find in our hands does not belong to us-we just had it first. We can honor that knowledge best by sharing it as widely as possible using the most creative means at our disposal.

    The global nature of ocean acidification (OA) transcends habitats, ecosystems, regions, and science disciplines. The scientific community recognizes that the biggest challenge in improving understanding of how changing OA conditions affect ecosystems, and associated consequences for human society, requires integration of experimental, observational, and modeling approaches from many disciplines over a wide range of temporal and spatial scales. Such transdisciplinary science is the next step in providing relevant, meaningful results and optimal guidance to policymakers and coastal managers. We discuss the challenges associated with integrating ocean acidification science across funding agencies, institutions, disciplines, topical areas, and regions, and the value of unifying science objectives and activities to deliver insights into local, regional, and global scale impacts. We identify guiding principles and strategies for developing transdisciplinary research in the ocean acidification science community.

  1. Carbon and Hydrogen Isotopic Composition of Plant Wax n-Alkanes: A Tool for Characterizing Soil Provenance in Forensic Science

    Science.gov (United States)

    Pedentchouk, N.; Wagner, T.; Jones, M.

    2009-04-01

    Forensic science is an integrative discipline that requires material evidence from diverse sources. Geochemical evidence derived from inorganic and organic substances is becoming increasingly popular among law enforcement agencies in industrialized countries. Previous investigations indicate that the relative distributions of individual plant-derived biomarkers found in soils are linked to the biomarker patterns found in the overlying vegetation. However, identification of soil provenance based on the distribution of plant-derived biomarkers for forensic purposes is inhibited by the fact that a significant number of terrestrial plant species have overlapping biomarker distributions. In order to enhance the resolving power of plant-derived biomarker signal, we propose to enhance the molecular approach by adding a stable isotope component, i.e. the delta13C/deltaD values of individual biomarkers. The first objective of this project is to determine the delta13C/deltaD signatures of n-alkanes derived from various higher plant types commonly growing in the UK. The second objective is to investigate whether the same species/plant types differ isotopically between two locations affected by different weather patterns in the UK: a relatively warmer and drier Norwich, Norfolk and a cooler and wetter Newcastle-upon-Tyne in NE England. The n-C29 alkane data from 14 tree species sampled during July 2007 and August 2008 in Newcastle show a clear negative trend between delta13C and deltaD values. When these data are plotted against each other, the six deciduous angiosperms (delta13C: c. -39 to -35 per mil; deltaD: c. -155 to -130 per mil) are completely separated from four evergreen angiosperms (delta13C: c. -33 to -28 per mil; deltaD: c. -195 to -165 per mil). The four gymnosperm species data plot between those of the deciduous and evergreen angiosperms. Because all 14 species in Newcastle experience the same environmental conditions, we suggest that the observed isotopic

    Nuclear forensics is the analysis of nuclear materials recovered from either the capture of unused materials, or from the radioactive debris following a nuclear explosion and can contribute significantly to the identification of the sources of the materials and the industrial processes used to obtain them. In the case of an explosion, nuclear forensics can also reconstruct key features of the nuclear device. Nuclear forensic analysis works best in conjunction with other law enforcement, radiological protection dosimetry, traditional forensics, and intelligence work to provide the basis for attributing the materials and/or nuclear device to its originators. Nuclear forensics is a piece of the overall attribution process, not a stand-alone activity

    Full Text Available The scarce attention to assessment and evaluation in science education research has been especially harmful for Science-Technology-Society (STS education, due to the dialectic, tentative, value-laden, and controversial nature of most STS topics. To overcome the methodological pitfalls of the STS assessment instruments used in the past, an empirically developed instrument (VOSTS, Views on Science-Technology-Society have been suggested. Some methodological proposals, namely the multiple response models and the computing of a global attitudinal index, were suggested to improve the item implementation. The final step of these methodological proposals requires the categorization of STS statements. This paper describes the process of categorization through a scaling procedure ruled by a panel of experts, acting as judges, according to the body of knowledge from history, epistemology, and sociology of science. The statement categorization allows for the sound foundation of STS items, which is useful in educational assessment and science education research, and may also increase teachers’ self-confidence in the development of the STS curriculum for science classrooms.

    Experts play a critical role in forensic decision making, even when cognition is offloaded and distributed between human and machine. In this paper, we investigated the impact of using Automated Fingerprint Identification Systems (AFIS) on human decision makers. We provided 3680 AFIS lists (a total of 55,200 comparisons) to 23 latent fingerprint examiners as part of their normal casework. We manipulated the position of the matching print in the AFIS list. The data showed that latent fingerprint examiners were affected by the position of the matching print in terms of false exclusions and false inconclusives. Furthermore, the data showed that false identification errors were more likely at the top of the list and that such errors occurred even when the correct match was present further down the list. These effects need to be studied and considered carefully, so as to optimize human decision making when using technologies such as AFIS. © 2011 American Academy of Forensic Sciences.

    2017-05-01

    Historically, reported cases of self-identified vampirism typically have been associated with psychopathology and sometimes a propensity for violence. However, scholars recently have noted a wide range of diverse practices and meanings that all fall under the general description of self-identified vampirism. This brief report focuses on a homicide case (male and female partnered offenders), wherein a single victim was murdered and dismembered. Due to specific case evidence, there was controversy regarding whether or not the homicide was motivated by ritualistic self-identified vampirism. Court documents were reviewed and assessed, and findings suggest that the evidence used to support assertions that homicidal motivations occurred due to ritualistic vampirism was misinterpreted due to the omission of a growing multidisciplinary literature on self-identified vampirism. It is important for forensic experts to be aware of emerging research on alternative identities, including vampirism, that challenge traditional theories and assumptions. © 2016 American Academy of Forensic Sciences.

    Destructive natural disasters such as earthquakes and tsunamis have occurred frequently in the world. For instance, 2004 Sumatra Earthquake in Indonesia, 2008 Wenchuan Earthquake in China, 2010 Chile Earthquake and 2011 Tohoku Earthquake in Japan etc., these earthquakes generated very severe damages. For the reduction and mitigation of damages by destructive natural disasters, early detection of natural disasters and speedy and proper evacuations are indispensable. And hardware and software developments/preparations for reduction and mitigation of natural disasters are quite important. In Japan, DONET as the real time monitoring system on the ocean floor is developed and deployed around the Nankai trough seismogenic zone southwestern Japan. So, the early detection of earthquakes and tsunamis around the Nankai trough seismogenic zone will be expected by DONET. The integration of the real time data and advanced simulation researches will lead to reduce damages, however, in the resilience society, the resilience methods will be required after disasters. Actually, methods on restorations and revivals are necessary after natural disasters. We would like to propose natural disaster mitigation science for early detections, evacuations and restorations against destructive natural disasters. This means the resilience society. In natural disaster mitigation science, there are lots of research fields such as natural science, engineering, medical treatment, social science and literature/art etc. Especially, natural science, engineering and medical treatment are fundamental research fields for natural disaster mitigation, but social sciences such as sociology, geography and psychology etc. are very important research fields for restorations after natural disasters. Finally, to realize and progress disaster mitigation science, human resource cultivation is indispensable. We already carried out disaster mitigation science under `new disaster mitigation research project on Mega

    The Spanish Society of Soil Science (in Spanish: Sociedad Española de la Ciencia del Suelo, SECS) was founded in 1947 by the Spanish National Research Council (CSIC) to promote cohesion and collaboration between soil science professionals, and with an innovative spirit and a willingness to serve the society. The objectives are: to promote the study, knowledge, research and protection of the soil; to spread, from a scientific point of view, the role played by the soil in favour of society, through ecosystem services such as the production of food and raw materials; The SECS also focus on the protection of other habitats and the conservation of our archaeological heritage; and to preserve knowledge of the soil, its management and use, both from the production and environmental point of view, leading to the optimization of its capabilities. The activities and services of the SECS are accessible on the web site www.secs.com.es, which is continually updated. In this contribution, we will show some examples of recent projects and activities developed by the SECS such as: the edition of the Spanish Journal of Soil Science (SJSS) since 2011; books like the white book on "Tratamiento del suelo en los libros de texto de ESO y Bachillerato en España" available in http://www.secs.com.es/archivo/libro-suelo.pdf, in which the term "Soil" is analysed in many secondary school books (152) in the Spanish education system; conferences, courses, exhibitions, expositions, calendars, the comic "Vivir en el suelo" in diferent languages, and diverse material to promote and disseminate the importance of the soil to the society; and last but not least, the Multingual Soil Science Dictionary (Spanish, Catalan, Gallician and Potuguese with translations in English and French (in process)) available online: http://cit.iec.cat/GLOSECS/inici.html.

    In a strange turn of history, the threat of global nuclear war has gone down, but the risk of a nuclear attack has gone up. The danger of nuclear terrorism and ways to thwart it, tackle it and manage it in the event of an attack is increasingly gaining the attention of nuclear analysts all over the world. There is rising awareness among nuclear experts to develop mechanisms to prevent, deter and deal with the threat of nuclear terrorism. Nuclear specialists are seeking to develop and improve the science of nuclear forensics so as to provide faster analysis during a crisis. Nuclear forensics can play an important role in detecting illicit nuclear materials to counter trafficking in nuclear and radiological materials. An effective nuclear forensic and attribution strategy can enable policy makers, decision makers and technical managers to respond to situations involving interception of special nuclear materials

    This paper provides an introduction to the discipline of Computer Forensics. With computers being involved in an increasing number, and type, of crimes the trace data left on electronic media can play a vital part in the legal process. To ensure acceptance by the courts, accepted processes and procedures have to be adopted and demonstrated which are not dissimilar to the issues surrounding traditional forensic investigations. This paper provides a straightforward overview of the three steps involved in the examination of digital media: Acquisition of data. Investigation of evidence. Reporting and presentation of evidence. Although many of the traditional readers of Medicine, Science and the Law are those involved in the biological aspects of forensics, I believe that both disciplines can learn from each other, with electronic evidence being more readily sought and considered by the legal community and the long, tried and tested scientific methods of the forensic community being shared and adopted by the computer forensic world.

    In the last two decades, the debate on the meaning of science in relation to societies that create it, nourish it, and benefit from it, focused on civil society's ability to produce knowledge. This yielded first the concept of participatory science and later the wider concept of participatory research. Throughout Europe, numerous collective experimentations have generated countless interactions, and new interfaces between the world of research and civil society are constantly being created. But in spite of the proliferation of these experiences, a paradox slows down their acknowledgment and legitimation. On the one hand, these interactions often go unseen and unrecognized by the institutions, public policies, and even at times their very creators. On the other hand, scientists, are still overwhelmingly wary of civil society and, perceiving only its intellectual deficit and lack of comprehension, they fail to consider the study and development of these interactions as being of primary importance. The Sciences and Society Alliance, which was recently founded in France, provides a platform where these collaborative experiences can be collected, studied, supported, communicated, and institutionally acknowledged. The launch of this process,which is soon to be European in scope, answers the need to bring science into the democratic path tread by the societies that create it. In its ability to compose diversity, this process is an example of deep democracy.

    Full Text Available In a meta-analysis carried out in 2002, the two main associations of science centres and museums (ASTC, mainly US-centered, and ECSITE, mainly European gathered all studies analysing the impact of science centres and museums on their local communities1. Four types of impact were identified: personal, social, political and economical. It was noticed that the vast majority of studies concentrated on the personal impact (that is, learning outcome, visitor satisfaction, etc., while the latter three were largely neglected. The very fact of pointing this out, and many recent experiences - some of which are included in this commentary - show that there is now a shift of attention.

    2008-01-01

    A critical review of the conceptual and practical evolution of forensic anthropology during the last two decades serves to identify two key external factors and four tightly inter-related internal methodological advances that have significantly affected the discipline. These key developments have not only altered the current practice of forensic anthropology, but also its goals, objectives, scope, and definition. The development of DNA analysis techniques served to undermine the classic role of forensic anthropology as a field almost exclusively focused on victim identification. The introduction of the Daubert criteria in the courtroom presentation of scientific testimony accompanied the development of new human comparative samples and tools for data analysis and sharing, resulting in a vastly enhanced role for quantitative methods in human skeletal analysis. Additionally, new questions asked of forensic anthropologists, beyond identity, required sound scientific bases and expanded the scope of the field. This environment favored the incipient development of the interrelated fields of forensic taphonomy, forensic archaeology, and forensic trauma analysis, fields concerned with the reconstruction of events surrounding death. Far from representing the mere addition of new methodological techniques, these disciplines (especially, forensic taphonomy) provide forensic anthropology with a new conceptual framework, which is broader, deeper, and more solidly entrenched in the natural sciences. It is argued that this new framework represents a true paradigm shift, as it modifies not only the way in which classic forensic anthropological questions are answered, but also the goals and tasks of forensic anthropologists, and their perception of what can be considered a legitimate question or problem to be answered within the field.

    The European Confederation of the Soil Science Societies (ECSSS) was founded not only to organize the Eurosoil congress, but also to continuously support and promote the soil causes in the European area. A work is in progress to define the best way to achieve this goal, with integrating voices of the European structures and networks, and the national societies. One of the major objectives is to develop a modern approach of soil protection, including leading experimentations shared with all the members, and active lobbying. Such an approach requires the buildup of an efficient interface with policy makers, stake holders, engineering and science, which should be concretized in a new the dimension of the Eurosoil congress. This communication will sketch the on-going work, with reviewing the perspectives, conditions, strengths, questions and difficulties identified.

    Soil taxation and soil classification are important drivers of soil science in Austria. However, the tasks are quite different: whereas soil taxation aims at the evaluation of the productivity potential of the soil, soil classification focusses on the natural development and - especially nowadays - on functionality of the soil. Since the foundation of the Austrian Soil Science Society (ASSS), representatives both directions of the description of the soil have been involved in the common actions of the society. In the first years it was a main target to improve and standardize field descriptions of the soil. Although both systems differ in the general layout, the experts should comply with identical approaches. According to this work, a lot of effort has been put into the standardization of the soil classification system, thus ensuring a common basis. The development, state of the art and further development of both classification and taxation systems initiated and carried out by the ASSS will be shown.

    Forensic advisors (FA) at the National Institute for Criminalistics and Criminology (NICC), generalists in forensic science, act as an advising body to the magistrate to improve communication between the various parties involved in the investigation: magistrate, police and crime scene investigators, and forensic experts. Their role is manifold, but their main objectives are to optimise trace processing by selecting the most pertinent traces in the context of the case and by advising magistrates on the feasibility of forensic analyses in particular circumstances in regards to the latest technical advances. Despite the absence of a legal framework governing their role and involvement in judicial cases, the demand for their services has increased over the years. Initially, forensic advisors were called for complex homicide cases. Due to the proximity with the Public Prosecutor's Office, the types of offences for which their expertise was sought have become more diverse (mainly including robbery, burglary and sexual assault cases), leading to a diversity in the types of cases handled by the forensic advisors (complex, simple and review). In many of the cases they are requested for, in addition to consulting on the best analytical strategy, forensic advisors also assume the role of case coordinator regarding the seized objects and their respective analyses. Indeed, in the majority of cases treated by the FAs, two or more types of expertise have been requested and performed, either at the internal laboratories of NICC or at external laboratories. This paper explains the role of the forensic advisors in Belgium, the path that let to their current status and problems encountered. Copyright © 2017 The Chartered Society of Forensic Sciences.

    2013-04-01

    The Soil Education and public awareness technical commission of the Brazilian Soil Science Society was created in 1987 as Soil Science teaching commission at that time. In the 90's of the last century the commission was very active and realized three national symposia in the years 1994 to 1996: in Viçosa, Minas Gerais; Santa Maria, Rio Grande do Sul and Pato Branco, Paraná. The following symposium scheduled to happen in Brasilia, 1997 could not be realized and was followed by a weakening and reduction of the involved group. Those three symposia were focused on the aspects of soil science taught at the university educational level, mainly in agrarian sciences. The concern about what was going on at basic education and perception by society was not much present. The commission was revitalized in 2005 and in 2007 realized its first meeting at the Brazilian Congress of Soil Science in Gramado, Rio Grande do Sul. At that meeting it was already an urge to assume the approach of soil education instead of soil science teaching, within a major concern how society consider soils. It was accepted and adequate under the structural reorganization undergone by the national society following the IUSS main lines. The commission was renamed and got two new mates at the newly created Division IV, Soils, Environment and Society, of the Brazilian Soil Science Society: Soils and Food Safety and History, Epistemology and Sociology of Soil Science. The national symposia were relaunched to happen biannually. An inventory of the soil education experiences around the country started and the geographic distribution of the future symposia intended to rescue and bring together experiences in different parts of the country that would not be known by other means. Three symposia were already realized: Piracicaba, Sao Paulo, 2008 (southeast); Curitiba, Paraná, 2010 (south) and Sobral, Ceará, 2012 (northeast). The next is planned to happen in Recife, Pernambuco in April 2014. The scope of the

    Full Text Available In present times it would not be appropriate to say art made a “debut” in science centres, as it has been a feature since the beginning of their history, and it appeared precisely in the ‘parent’ science centre, the Exploratorium. However, now it is time to check the progress. There is unrest for this issue, as in history-making times, and it is worthwhile to follow the new developments and hear the words of the coordinators of the artistic activities in science centres and, more in general, in science museums, and also of the artists involved in the process. The goal is to promote a debate on the final results of this phenomenon and on what will happen next. Also, emphasis should be put on the importance for each museum to define right from the start an ‘art policy’, even a complex one, but somehow structured, that may be employed at many levels according to the needs of the museum itself.

    The Japanese Society of Neuropsychopharmacology (NP) has established a Translational Medical Science Committee (TMSC), which is introduced in this article. In this century, the Japanese Government has made great effort to establish highly organized supporting systems for translational research (TR); however, clinical developments for psychotropic drugs in Japan are facing stagnation. TMSC will provide advisory activities from an academic point of view in this field, which will be result in the improvement of people's health.

  2. Evaluation of mixed-source, low-template DNA profiles in forensic science.

    2013-07-23

    Enhancements in sensitivity now allow DNA profiles to be obtained from only tens of picograms of DNA, corresponding to a few cells, even for samples subject to degradation from environmental exposure. However, low-template DNA (LTDNA) profiles are subject to stochastic effects, such as "dropout" and "dropin" of alleles, and highly variable stutter peak heights. Although the sensitivity of the newly developed methods is highly appealing to crime investigators, courts are concerned about the reliability of the underlying science. High-profile cases relying on LTDNA evidence have collapsed amid controversy, including the case of Hoey in the United Kingdom and the case of Knox and Sollecito in Italy. I argue that rather than the reliability of the science, courts and commentators should focus on the validity of the statistical methods of evaluation of the evidence. Even noisy DNA evidence can be more powerful than many traditional types of evidence, and it can be helpful to a court as long as its strength is not overstated. There have been serious shortcomings in statistical methods for the evaluation of LTDNA profile evidence, however. Here, I propose a method that allows for multiple replicates with different rates of dropout, sporadic dropins, different amounts of DNA from different contributors, relatedness of suspected and alternate contributors, "uncertain" allele designations, and degradation. R code implementing the method is open source, facilitating wide scrutiny. I illustrate its good performance using real cases and simulated crime scene profiles.

    The experience of villagers in Maimafu, in the Crater Mountain Wildlife Management Area of the Eastern Highlands of Papua New Guinea, calls attention to two forms of social interaction between rural people and outsiders that have been little examined in the anthropological literature. One of these is scientific research and the other is scientific tourism, a form of ecotourism that is linked not to science but to self-fashioning and individual gain. Scientific tourists may be seeking an educational adventure that they can turn into symbolic capital on their return home, a way into the world of science, or an experience that can be turned into economic capital through publication in popular magazines. For both researchers and scientific journalists, New Guinea combines the exotic, the about-to-be-lost, the primitive, the untouched, and the spectacular and is therefore a powerful space for imaginary and representational practice.

  6. Experiencing biodiversity as a bridge over the science-society communication gap.

    2014-06-01

    Drawing on the idea that biodiversity is simply the diversity of living things, and that everyone knows what diversity and living things mean, most conservation professionals eschew the need to explain the many complex ways in which biodiversity is understood in science. On many biodiversity-related issues, this lack of clarity leads to a communication gap between science and the general public, including decision makers who must design and implement biodiversity policies. Closing this communication gap is pivotal to the ability of science to inform sound environmental decision making. To address this communication gap, we propose a surrogate of biodiversity for communication purposes that captures the scientific definition of biodiversity yet can be understood by nonscientists; that is, biodiversity as a learning experience. The prerequisites of this or any other biodiversity communication surrogate are that it should have transdisciplinary relevance; not be measurable; be accessible to a wide audience; be usable to translate biodiversity issues; and understandably encompass biodiversity concepts. Biodiversity as a learning experience satisfies these prerequisites and is philosophically robust. More importantly, it can effectively contribute to closing the communication gap between biodiversity science and society at large. © 2013 Society for Conservation Biology.

    Full Text Available The focus is on the practices of secondary science teachers in rural, resource-extraction-based communities in the boreal region of northern Ontario, Canada. In 2008 the Ontario Ministry of Education mandated that science teaching and learning should bring to the forefront consideration of the impacts of science on society and environment, and include environmental education; topics that are particularly pertinent given the location(s of the study in logging and mining towns. Three years after the introduction of that curriculum the researcher investigates the extent to which the mandated changes have entered teacher practice. The study consists of a survey, (n= 26, interviews (n=7 and a closer exploration of the collaboration between two teachers who work towards including social and environmental issues in their lessons. Findings provide evidence that secondary science teachers are shifting toward a stronger emphasis issues of society and environment in their practice, however teachers identified a number of concerns including an information gap, developing new lessons, program planning, assessment, and teaching in the North. A theoretical framework developed by Pedretti and Nazir was used in the analysis of the teacher collaboration. Recommendations are for professional development to specifically address the concerns raised by the teachers; as well, changes are suggested to the theoretical framework to include a stronger emphasis on environmental education.

    2010-01-01

    With the completed sequence of the human genome has come the prospect of substantially improving the quality of life for millions through personalized medicine approaches. Still, any advances in this direction require research involving human subjects. For decades science and ethics have enjoyed an allegiance reflected in a common set of ethical principles and procedures guiding the conduct of research with human subjects. Some of these principles emphasize avoiding harm over maximizing benefit. In this paper we revisit the priority given to these ethical principles - particularly the principles that support a cautious approach to science - and propose a reframing of the 'social contract' between science and society that emphasizes reciprocity and meeting public needs.

    Increasing human population interacts with local and global environments to deplete biodiversity and resources humans depend on, thus challenging societal values centered on growth and relying on technology to mitigate environmental stress. Although the need to address the environmental crisis, central to conservation science, generated greener versions of the growth paradigm, we need fundamental shifts in values that ensure transition from a growth-centered society to one acknowledging biophysical limits and centered on human well-being and biodiversity conservation. We discuss the role conservation science can play in this transformation, which poses ethical challenges and obstacles. We analyze how conservation and economics can achieve better consonance, the extent to which technology should be part of the solution, and difficulties the "new conservation science" has generated. An expanded ambition for conservation science should reconcile day-to-day action within the current context with uncompromising, explicit advocacy for radical transitions in core attitudes and processes that govern our interactions with the biosphere. A widening of its focus to understand better the interconnectedness between human well-being and acknowledgment of the limits of an ecologically functional and diverse planet will need to integrate ecological and social sciences better. Although ecology can highlight limits to growth and consequences of ignoring them, social sciences are necessary to diagnose societal mechanisms at work, how to correct them, and potential drivers of social change.

    Forensic anthropology represents a dynamic and rapidly evolving complex discipline within anthropology and forensic science. Academic roots extend back to early European anatomists but development coalesced in the Americas through high-profile court testimony, assemblage of documented collections and focused research. Formation of the anthropology section of the American Academy of Forensic Sciences in 1972, the American Board of Forensic Anthropology in 1977/1978 and other organizational advances provided important stimuli for progress. While early pioneers concentrated on analysis of skeletonized human remains, applications today have expanded to include complex methods of search and recovery, the biomechanics of trauma interpretation, isotopic analysis related to diet and region of origin, age estimation of the living and issues related to humanitarian and human rights investigations. © 2018 Wiley Periodicals, Inc.

    This paper outlines the development and convergence of forensic science and secure psychiatric services in the UK, locating the professionalization of forensic nursing within a complex web of political, economic, and ideological structures. It is suggested that a stagnation of the therapeutic enterprise in high and medium security provision has witnessed an intrusion of medical power into the societal body. Expanding technologies of control and surveillance are discussed in relation to the move from modernity to postmodernity and the ongoing dynamic of medicalized offending. Four aspects of globalization are identified as impacting upon the organization and application of forensic practice: (i) organized capitalism and the exhaustion of the welfare state; (ii) security versus danger and trust versus risk; (iii) science as a meta-language; and (iv) foreclosure as a mechanism of censorship. Finally, as a challenge for the profession, some predictions are offered about the future directions or demise of forensic nursing.

    Barnard College and Columbia University's Center for New Media Teaching and Learning's Brownfield Action is a digital web-based, interactive simulation that combines lecture, laboratory exercises, and individual and collaborative out-of-classroom assignments. The objective of the instruction is to locate and define a subsurface plume of gasoline whose point source is a leaking underground storage tank (LUST) at a gas station. In the fall of 2009, fifteen pre-college high school students from the five boroughs of New York City used Brownfield Action in a 12-week after-school enrichment program at Barnard to investigate the gasoline plume using a variety of geophysical methods - excavation, ground penetrating radar, magnetic metal detection, soil gas, and drilling. The investigation resulted in individual Phase One Site Assessment Reports about the LUST. As coordinators and instructors of the program, we will share our experience teaching the students and the advantages and challenges of using a digital simulation as an instructional centerpiece. Such instruction is intended to include civic engagement and responsibility as part of science education and to create a curriculum that, instead of relying on fragmented and abstract instruction, provides students with a realistic, inquiry-based, and interdisciplinary construction of knowledge.

Enable all children to acquire the problem-solving, thinking, and communication skills of scientists – so that they can be productive and competitive in the new world economy.2. Generate a “scientific temper” for each nation, with scientifically trained people in many professions, ensuring the rationality and the tolerance essential for a democratic society.3. Help each nation generate new scientific knowledge and technology by casting the widest possible net for talent.My preferred strategy for the United States:1. Science education should have a much larger role in all school systems, but only if this science education is of a different kind than is experienced in most schools today.2. Making such a change will require a redefinition of what we mean by the term  “science education”.3. To create continually improving education systems, we will need much more collaborative, effective, and use-inspired education research - research that is focused on real school needs and that integrates the best school teachers into the work.4. Our best teachers need to have a much larger voice in helping to steer our national and state policies, as well as in our local school systems!

    The Southern California Earthquake Center (SCEC) has been developing groundbreaking computer modeling capabilities for studying earthquakes. These visualizations were initially shared within the scientific community but have recently gained visibility via television news coverage in Southern California. Computers have opened up a whole new world for scientists working with large data sets, and students can benefit from the same opportunities (Libarkin & Brick, 2002). For example, The Great Southern California ShakeOut was based on a potential magnitude 7.8 earthquake on the southern San Andreas fault. The visualization created for the ShakeOut was a key scientific and communication tool for the earthquake drill. This presentation will also feature SCEC Virtual Display of Objects visualization software developed by SCEC Undergraduate Studies in Earthquake Information Technology interns. According to Gordin and Pea (1995), theoretically visualization should make science accessible, provide means for authentic inquiry, and lay the groundwork to understand and critique scientific issues. This presentation will discuss how the new SCEC visualizations and other earthquake imagery achieve these results, how they fit within the context of major themes and study areas in science communication, and how the efficacy of these tools can be improved.

This proposal is based on a lack of understanding of the realities of forensic voice comparison. If it were implemented, it would make data-based forensic voice comparison analysis within the likelihood ratio framework virtually impossible. We argue that it would also lead forensic speech scientists to present invalid unreliable strength of evidence statements, and not allow them to conduct the tests that would make them aware of this problem.

    Forensic science, commonly referred to as forensics, is the examination of physical, biological, behavioural and documentary evidence. The goal of forensics is to discover linkages among people, places, things and events. A sub-discipline of forensic science, nuclear forensics is the analysis of intercepted illicit nuclear or radioactive material and any associated material, which can assist in law enforcement investigations as well as assessments of the potential vulnerabilities associated with the use, production and storage of these materials as part of a nuclear security infrastructure. The analysis of nuclear or other radioactive material seeks to identify what the materials are, how, when, and where the materials were made, and what their intended uses were. Nuclear forensics is an important tool in the fight against illicit trafficking in nuclear and radiological material

    Risk and Society is the sixth volume in Kluwer's Technology, Risk, and Society series, and like the previous volumes in this series, it is made up of papers presented at a symposium convened in 1989 to discuss the changing interactions of technology and society and definitions of risk. The papers presented all center around risk as a constructed phenomenon. The first paper is a general overview of concepts of risk in society and the changing emphasis on risk in the last two decades. The papers represent four main topic areas: Risk, science and public policy; Allocating scarce medical resources; Nuclear power and nuclear waste disposal; and Setting standards for air quality. Three papers, representing three different points of view, are presented in each topic area. The contributors cover a range of issues in this format, and the combined effect is a good overview of the issues with which risk assessors, risk managers, and public policymakers must grapple if constructive use is to be made of risk in public decision-making

    Veterinary forensic pathology is emerging as a distinct discipline, and this special issue is a major step forward in establishing the scientific basis of the discipline. A forensic necropsy uses the same skill set needed for investigations of natural disease, but the analytical framework and purpose of forensic pathology differ significantly. The requirement of legal credibility and all that it entails distinguishes the forensic from routine diagnostic cases. Despite the extraordinary depth and breadth of knowledge afforded by their training, almost 75% of veterinary pathologists report that their training has not adequately prepared them to handle forensic cases. Many veterinary pathologists, however, are interested and willing to develop expertise in the discipline. Lessons learned from tragic examples of wrongful convictions in medical forensic pathology indicate that a solid foundation for the evolving discipline of veterinary forensic pathology requires a commitment to education, training, and certification. The overarching theme of this issue is that the forensic necropsy is just one aspect in the investigation of a case of suspected animal abuse or neglect. As veterinary pathologists, we must be aware of the roles filled by other veterinary forensic experts involved in these cases and how our findings are an integral part of an investigation. We hope that the outcome of this special issue of the journal is that veterinary pathologists begin to familiarize themselves with not only forensic pathology but also all aspects of veterinary forensic science. © The Author(s) 2016.

    Students learn science by actually performing science activities. The 12 laboratories described in this article assist students in applying the fundamental techniques germane to the field of forensic science to "solve" contrived cases and present "evidence" in a mock trial. Moreover, students are also confronted with some of the legal and ethical issues concerning the validity, reliability, and application of some forensic techniques. The pedagogical design of the laboratory course provides a rich, challenging, and interdisciplinary academic experience intended to augment and compliment the didactic forensic lecture portion of the course. This laboratory course was designed to engender, embody, and articulate one of the University's directive goals to support interdisciplinary teaching, research, and programming. Because we developed the laboratories on minimal funds, we demonstrated that it could be cost-effective. And thus, we recommend a laboratory science course be included as part of the curriculum of all forensic nursing students and practitioners. © 2011 International Association of Forensic Nurses.

    The problem in the science learning process is the application of the scientific approach takes a long time in order to provide conceptual understanding to the students, there is no teaching materials that can measure students reasoning and thinking ability, and the assessment has not measured students reasoning and literacy skills.The effort can be done is to develop science technology society module indue science literacy assessment. The purpose of the research was to produce a module oriented society indue science science technology literacy assessment. The research is development research using Plomp model, consist of preliminary, prototyping, and assessment phase. Data collect by questionnare and documantion. The result there is science technology society module indue science literacy assessment is very valid.

    The Austrian Soil Science Society (ASSS), founded in 1954, is a non-profit organisation aiming at furthering all branches of soil science in Austria. The ASSS provides information on the current state of soil research in Austria and abroad. It organizes annual conferences for scientists from soil and related sciences to exchange their recent studies and offers a journal for scientific publications. Annually, ASSS awards the Kubiena Research Prize for excellent scientific studies provided by young scientists. In order to conserve and improve soil science in the field, excursions are organized, also in cooperation with other scientific organisations. Due to well-established contacts with soil scientists and soil science societies in many countries, the ASSS is able to provide its members with information about the most recent developments in the field of soil science. This contributes to a broadening of the current scientific knowledge on soils. The ASSS also co-operates in the organisation of excursions and meetings with neighbouring countries. Several members of the ASSS teach soil science at various Austrian universities. More detail on said conferences, excursions, publications and awards will be given in the presentation. Beside its own scientific journal, published once or twice a year, and special editions such as guidebooks for soil classification, the ASSS runs a website providing information on the Society, its activities, meetings, publications, awards and projects. Together with the Environment Agency Austria the ASSS runs a soil platform on the internet. It is accessible for the public and thus informs society about soil issues. This platform offers a calendar with national and international soil events, contacts of soil related organisations and networks, information on national projects and publications. The society has access to products, information material and information on educational courses. Last but not least information on specific soil

    Public acceptance of matters relating to radioactive waste management can properly be sought through education, but what are the particulars to be considered and what is the strategy for success? The issues of science, technology and society which must be addressed are explored here and seen to be inextricably related, so that none of them can gain adequate attention except it be presented in the context of the others. Such issues include the concept of acceptable levels of risk, which must become familiar and applied with no greater severity to the nuclear industry than to other aspects of life

    Full Text Available A working model of consciousness is fundamental to understanding of the interactions of the observer in science. This paper examines contemporary understanding of consciousness. A heuristic model of consciousness is suggested that is consistent with psycophysics measurements of bandwidth of consciousness relative to unconscious perception. While the self reference nature of consciousness confers a survival benefit by assuring the all points of view regarding a problem are experienced in sufficiently large population, conscious bandwidth is constrained by design to avoid chaotic behavior. The multiple hypotheses provided by conscious reflection enable the rapid progression of science and technology. The questions of free will and the problem of attention are discussed in relation to the model. Finally the combination of rapid technology growth with the assurance of many unpredictable points of view is considered in respect to contemporary constraints to the development of society.

    2015-01-01

    Strontium isotopes ((87)Sr/(86)Sr) can be useful biological markers for a wide range of forensic science applications, including wildlife tracking. However, one of the main advantages of using (87)Sr/(86)Sr values, that there is no fractionation from geological bedrock sources through the food web, also happens to be a critical assumption that has never been tested experimentally. We test this assumption by measuring (87)Sr/(86)Sr values across three trophic levels in a controlled greenhouse experiment. Adult monarch butterflies were raised on obligate larval host milkweed plants that were, in turn, grown on seven different soil types collected across Canada. We found no significant differences between (87)Sr/(86)Sr values in leachable Sr from soil minerals, organic soil, milkweed leaves, and monarch butterfly wings. Our results suggest that strontium isoscapes developed from (87)Sr/(86)Sr values in bedrock or soil may serve as a reliable biological marker in forensic science for a range of taxa and across large geographic areas.

  15. Making Kew Observatory: the Royal Society, the British Association and the politics of early Victorian science.

    Macdonald, Lee T

    2015-09-01

    Built in 1769 as a private observatory for King George III, Kew Observatory was taken over in 1842 by the British Association for the Advancement of Science (BAAS). It was then quickly transformed into what some claimed to be a 'physical observatory' of the sort proposed by John Herschel - an observatory that gathered data in a wide range of physical sciences, including geomagnetism and meteorology, rather than just astronomy. Yet this article argues that the institution which emerged in the 1840s was different in many ways from that envisaged by Herschel. It uses a chronological framework to show how, at every stage, the geophysicist and Royal Artillery officer Edward Sabine manipulated the project towards his own agenda: an independent observatory through which he could control the geomagnetic and meteorological research, including the ongoing 'Magnetic Crusade'. The political machinations surrounding Kew Observatory, within the Royal Society and the BAAS, may help to illuminate the complex politics of science in early Victorian Britain, particularly the role of 'scientific servicemen' such as Sabine. Both the diversity of activities at Kew and the complexity of the observatory's origins make its study important in the context of the growing field of the 'observatory sciences'.

  18. Psychiatric/ psychological forensic report writing.

    Science.gov (United States)

    Young, Gerald

    Approaches to forensic report writing in psychiatry, psychology, and related mental health disciplines have moved from an organization, content, and stylistic framework to considering ethical and other codes, evidentiary standards, and practice considerations. The first part of the article surveys different approaches to forensic report writing, including that of forensic mental health assessment and psychiatric ethics. The second part deals especially with psychological ethical approaches. The American Psychological Association's Ethical Principles and Code of Conduct (2002) provide one set of principles on which to base forensic report writing. The U.S. Federal Rules of Evidence (2014) and related state rules provide another basis. The American Psychological Association's Specialty Guidelines for Forensic Psychology (2013) provide a third source. Some work has expanded the principles in ethics codes; and, in the third part of this article, these additions are applied to forensic report writing. Other work that could help with the question of forensic report writing concerns the 4 Ds in psychological injury assessments (e.g., conduct oneself with Dignity, avoid the adversary Divide, get the needed reliable Data, Determine interpretations and conclusions judiciously). One overarching ethical principle that is especially applicable in forensic report writing is to be comprehensive, scientific, and impartial. As applied to forensic report writing, the overall principle that applies is that the work process and product should reflect integrity in its ethics, law, and science. Four principles that derive from this meta-principle concern: Competency and Communication; Procedure and Protection; Dignity and Distance; and Data Collection and Determination. The standards or rules associated with each of these principles are reviewed. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

  19. Using online pedagogy to explore student experiences of Science-Technology-Society-Environment (STSE) issues in a secondary science classroom

    Science.gov (United States)

    Ayyavoo, Gabriel Roman

    With the proliferation of 21st century educational technologies, science teaching and learning with digitally acclimatized learners in secondary science education can be realized through an online Science-Technology-Society-Environment (STSE)-based issues approach. STSE-based programs can be interpreted as the exploration of socially-embedded initiatives in science (e.g., use of genetically modified foods) to promote the development of critical cognitive processes and to empower learners with responsible decision-making skills. This dissertation presents a case study examining the online environment of a grade 11 physics class in an all-girls' school, and the outcomes from those online discursive opportunities with STSE materials. The limited in-class discussion opportunities are often perceived as low-quality discussions in traditional classrooms because they originate from an inadequate introduction and facilitation of socially relevant issues in science programs. Hence, this research suggests that the science curriculum should be inclusive of STSE-based issue discussions. This study also examines the nature of students' online discourse and, their perceived benefits and challenges of learning about STSE-based issues through an online environment. Analysis of interviews, offline classroom events and online threaded discussion transcripts draws from the theoretical foundations of critical reflective thinking delineated in the Practical Inquiry (P.I.) Model. The PI model of Cognitive Presence is situated within the Community of Inquiry framework, encompassing two other core elements, Teacher Presence and Social Presence. In studying Cognitive Presence, the online STSE-based discourses were examined according to the four phases of the P.I. Model. The online discussions were measured at macro-levels to reveal patterns in student STSE-based discussions and content analysis of threaded discussions. These analyses indicated that 87% of the students participated in

    Introductory-level Earth science courses provide the opportunity for science and non-science majors to expand discipline-specific content knowledge while enhancing skill sets applicable to all disciplines. The outcomes of the student work can then benefit the education and outreach efforts of an international organization - in this case, a wiki devoted exclusively to the geosciences, managed by the Society of Exploration Geophysicists (SEG). The course Environment Earth at Penn State Brandywine is a general education science course with the overarching course goal for students to understand, communicate examples, and make informed decisions relating to big ideas and fundamental concepts of Earth science. To help accomplish this goal, students carry out a semester-long digital engaged scholarship project that benefits the users of the SEG Wiki (http://wiki.seg.org/). To begin with developing the literacy of students and their ability to read, interpret, and evaluate sources of scientific news, the first assignment requires students to write an annotated bibliography on a specific topic that serves as the foundation for a new SEG Wiki article. Once students have collected and summarized information from reliable sources, students learn how writing for a wiki is different than writing a term paper and begin drafting their wiki page. Students peer review each other's work for content and clarity before publishing their work on the SEG wiki. Students respond positively to this project, reporting a better understanding of and respect towards the authors of online wiki pages, as well as an overall satisfaction of knowing their work will benefit others. Links to student-generated pages and instructional materials can be found at: http://sites.psu.edu/segwiki/.

  1. The Impact of the SESAME Project on Science and Society in the Middle East

    2008-04-01

    SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) is a UNESCO-sponsored project that is constructing an international research laboratory, closely modeled on CERN, in Jordan (www.sesame.org.jo). Ten Members of the governing Council (Bahrain, Cyprus, Egypt, Iran, Iraq, Israel, Jordan, Pakistan, Palestinian Authority, and Turkey) have responsibility for the project, led by Herwig Schopper, Council President since 1999. In late 2008 Chris Llewellyn-Smith will become Council President. SESAME was initiated by a gift from Germany of the decommissioned BESSY I facility. The BESSY I 0.8 GeV injector is now being installed in the recently completed building, funded by Jordan, as components are procured for a new 133 m circumference, 2.5 GeV third-generation storage ring with 12 locations for insertion devices. Beam line equipment has been provided by laboratories in France, UK, and US. Support also comes from EU, IAEA, ICTP, Japan Society for the Promotion of Science, the US Department of Energy and State Department, and laboratories around the world. The broad scientific program includes biomedical, environmental, and archaeological programs particularly relevant to the Middle East. Five scientific workshops and six annual Users' meetings have brought together several hundred scientists from the region, along with researchers from around the world. Training programs have enabled about 100 scientists from the region to work at synchrotron radiation laboratories. These activities have already had significant impact on science and society in the Middle East, for example leading to collaborations between scientists from countries that are not particularly friendly with each other, and to national planning emphasizing synchrotron radiation research. When research starts in 2011 this impact will grow as graduate students are trained in the region in many scientific disciplines, and scientists working abroad are attracted to return.

    The British Society for Soil Science (BSSS) http://www.soils.org.uk is an international membership organisation and UK based charity committed to promoting the study and profession of soil science in its widest aspects. The Society is committed to reaching out to the public at large to educate and inform on the importance of soils to us all. The Society has adopted a range of approaches to soil education, tailored to the needs and aims of different audience types. We have developed the 'Working with Soil' initiative http://www.soilscientist.org/workingwithsoil which provides practicing soil scientists and potential funders with a set of professional competencies aligned to specific aspects of work. From 2013 The Society has developed a program of courses aligned to these documents aimed at meeting the professional development needs of those undertaking such work. So far these have focused on fundamentals of field characterisation, sampling and mapping which have been very well received, especially by early career practitioners who have had less exposure to field work. We have also produced posters and leaflets that demonstrate a range of soil functions which support human society, for example 'Soils in the City' and 'Soils of Britain'. These were originally developed in a more traditional formal style. The materials have also proved popular with local authorities, regional horticultural clubs and higher education establishments, notably agricultural colleges where they have been used to support student learning in both timetabled and project work. We have subsequently produced a further set of materials aimed at a much younger audience. We deliberately chose slightly quirkier names for these, for example 'Soils and Time Travel' and 'Soils and Spaceship Earth' as a hook to capture the child's imagination. These were designed by a specialist company who used a less formal language, the use of cartoons and alternative images and a wider range of font styles and sizes

    2008-01-01

    The transdisciplinary research project Virtopsy is dedicated to implementing modern imaging techniques into forensic medicine and pathology in order to augment current examination techniques or even to offer alternative methods. Our project relies on three pillars: three-dimensional (3D) surface scanning for the documentation of body surfaces, and both multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) to visualise the internal body. Three-dimensional surface scanning has delivered remarkable results in the past in the 3D documentation of patterned injuries and of objects of forensic interest as well as whole crime scenes. Imaging of the interior of corpses is performed using MSCT and/or MRI. MRI, in addition, is also well suited to the examination of surviving victims of assault, especially choking, and helps visualise internal injuries not seen at external examination of the victim. Apart from the accuracy and three-dimensionality that conventional documentations lack, these techniques allow for the re-examination of the corpse and the crime scene even decades later, after burial of the corpse and liberation of the crime scene. We believe that this virtual, non-invasive or minimally invasive approach will improve forensic medicine in the near future. (orig.)

However, we revisit the discussion to increase the awareness among forensic genetic practitioners and include new information on medical and societal factors to assess the risk of not considering a monozygotic twin as the true perpetrator......, then data relevant for the Danish society suggests that the threshold of likelihood ratios should approximately be between 150,000 and 2,000,000 in order to take the risk of an unrecognised identical, monozygotic twin into consideration.

    An Android social app taxonomy incorporating artifacts that are of forensic interest will enable users and forensic investigators to identify the personally identifiable information (PII) stored by the apps. In this study, 30 popular Android social apps were examined. Artifacts of forensic interest (e.g., contacts lists, chronology of messages, and timestamp of an added contact) were recovered. In addition, images were located, and Facebook token strings used to tie account identities and gain access to information entered into Facebook by a user were identified. Based on the findings, a two-dimensional taxonomy of the forensic artifacts of the social apps is proposed. A comparative summary of existing forensic taxonomies of different categories of Android apps, designed to facilitate timely collection and analysis of evidentiary materials from Android devices, is presented. © 2016 American Academy of Forensic Sciences.

  11. Digital Forensics to Intelligent Forensics

    Directory of Open Access Journals (Sweden)

    Alastair Irons

    2014-09-01

    Full Text Available In this paper we posit that current investigative techniques—particularly as deployed by law enforcement, are becoming unsuitable for most types of crime investigation. The growth in cybercrime and the complexities of the types of the cybercrime coupled with the limitations in time and resources, both computational and human, in addressing cybercrime put an increasing strain on the ability of digital investigators to apply the processes of digital forensics and digital investigations to obtain timely results. In order to combat the problems, there is a need to enhance the use of the resources available and move beyond the capabilities and constraints of the forensic tools that are in current use. We argue that more intelligent techniques are necessary and should be used proactively. The paper makes the case for the need for such tools and techniques, and investigates and discusses the opportunities afforded by applying principles and procedures of artificial intelligence to digital forensics intelligence and to intelligent forensics and suggests that by applying new techniques to digital investigations there is the opportunity to address the challenges of the larger and more complex domains in which cybercrimes are taking place.

  12. Science & Society seminar: Evolution is not only a story of genes

    CERN Multimedia

    2002-01-01

    Memes are behaviours and ideas copied from person to person by imitation. These include songs, habits, skills, inventions and ways of doing things. Darwinian evolutionary theory, which holds that genes control the traits of organisms, has traditionally explained human nature. Susan Blackmore offers a new look at evolution, and considers evolving memes as well as genes. This will be the subject of the next Science and Society seminar, 'The evolution of Meme machines', that will take place on Thursday 24 October. According to the meme idea, everything changed in human evolution when imitation first appeared because imitation let loose a new replicator, the meme. Since that time, two replicators have been driving human evolution, not one. This is why humans have such big brains, and why they alone produce and understand grammatical language, sing, dance, wear clothes and have complex cumulative cultures. Unlike other brains, human brains had to solve the problem of choosing which memes to imitate. In other wor...

    Student’s communication skill paid less attention in learning activity at school, even though communication skill is needed by students in the 21st century based on the demands of new curriculum in Indonesia (K13). This study focuses on drilling students’ communication skill through science, environment, technology, and society (SETS)-based learning. The research is a pre-experimental design with a one-shot case study model involving 10 students of ninth-grader of SMPN 2 Manyar, Gresik. The research data were collected through observation method using communication observation sheet. The data were analyzed using the descriptive qualitative method. The result showed that students’ communication skill reached the completeness of skills decided both individually and classically in the curriculum. The fundamental result of this research that SETS-based learning can be used to drill students’ communication skill in K13 context.

  14. Dear Professor Dyson twenty years of correspondence between Freeman Dyson and undergraduate students on science, technology, society and life

    CERN Document Server

    Neuenschwander, Dwight E

    2016-01-01

    Freeman Dyson has designed nuclear reactors and bomb-powered spacecraft; he has studied the origins of life and the possibilities for the long-term future; he showed quantum mechanics to be consistent with electrodynamics and started cosmological eschatology; he has won international recognition for his work in science and for his work in reconciling science to religion; he has advised generals and congressional committees. An STS (Science, Technology, Society) curriculum or discussion group that engages topics such as nuclear policies, genetic technologies, environmental sustainability, the role of religion in a scientific society, and a hard look towards the future, would count itself privileged to include Professor Dyson as a class participant and mentor. In this book, STS topics are not discussed as objectified abstractions, but through personal stories. The reader is invited to observe Dyson's influence on a generation of young people as they wrestle with issues of science, technology, society, life in g...

    Natural disasters like the 2004 tsunami bear graphic testimony to the Earth's incredible power. More effective use of geoscientific knowledge can save lives and protect property. Such knowledge also enables us to satisfy, in a sustainable manner,the growing need for Earth's resources by an expanding human population. Such knowledge is readily available in the practical experience and publications of some half a million Earth scientists all over the world, a professional community that is ready and willing to contribute to a safer, healthier and wealthier society if called upon by politicians and decision makers. Professional guidance by Earth scientists is available in many aspects of everyday life including, for example, identification of the best areas for urban expansion, sites to avoid for waste disposal, the location of new underground fresh water resources, and where certain toxic agents implicated in Earth-related diseases may be located, etc.The International Year of Planet Earth (2007-2009) aims to build on existing knowledge and make it more available for the improvement of everyday life, especially in the less developed countries, as expressed in the Year's subtitle: Earth sciences for Society. Ambitious outreach and science programmes constitute the backbone of the International Year, now politically endorsed by all 191 member states of the United Nations Organisation which has proclaimed 2008, the central year of the triennium, as the UN Year of Planet Earth. This paper describes who is behind the initiative,how it will work, and how the political process leading to United Nations proclamation proceeded. It also describes the financial and organisational aspects of the International Year, sets out the commitments necessary for the realization of the Year's ambitions by all nations, and explains how the raising of US$ 20 million will be approached.

     The 10th Annual Meeting of the Japanese Society for Pharmaceutical Palliative Care and Sciences was held at Act City Hamamatsu, Japan, with a total of 2634 participants in attendance. The theme of the meeting was realized through a number of new concepts, such as a debate symposium, information sessions, nurses' workshops, and so on. The results obtained from the participation questionnaire (n=438), which were aggregated up to 1 month following the end of this year's meeting, revealed that 89% of the participants at considered it to have been appealing. In particular, 63% of the participants favored the adoption of a debate symposium whereby it was possible to ask and respond to questions in real time. In the free comments section of the questionnaire, the participants expressed how they felt the debate symposium made it easy to give their opinions, and that this element might be further developed in the future. They also stated that they found the introduction of the Clica system effective in terms of making the annual meeting an active learning place. One issue that was highlighted concerned the observation that the hall used to host the symposium was designed as a concert venue, which meant it was highly shielded from the outside environment, in addition to access to the internet being blocked. I hope that many of the projects from this Annual Meeting will serve to guide the future style of the Society's Annual Meetings.

    Soils are a finite natural resource and are nonrenewable on a human time scale. Soils are the foundation for food, animal feed, fuel and natural fiber production, the supply of clean water, nutrient cycling and a range of ecosystem functions. The area of fertile soils covering the world's surface is limited and increasingly subject to degradation, poor management and loss to urbanization. Increased awareness of the life-supporting functions of soil is called for if this trend is to be reversed and so enable the levels of food production necessary to meet the demands of population levels predicted for 2050. The Soil Science Society of America is coordinating with the Global Soil Partnership and other organizations around the world to celebrate the 2015 International Year of Soils and raise awareness and promote the sustainability of our limited soil resources. We all have a valuable role in communicating vital information on soils, a life sustaining natural resource. Therefore, we will provide resources to learn about soils and help us tell the story of soils. We will promote IYS on social media by sharing our posts from Facebook and Twitter. Additionally SSSA developed 12 monthly themes that reflect the diverse value of soils to our natural environment and society. Each month has information on the theme, a lesson plan, and other outreach activities. All information is available on a dedicated website www.soil.org/IYS. The site will be updated constantly throughout the year.

    Space exploration utilizes some of the latest and highest technology available to human kind; synonymous with space exploration is the mission patch. This specialized art form popularizes the exploration of space with millions of mission patches sold around the world. Space tourism and education centres like the Kennedy Space Centre rely heavily on each space shuttle launch to support their merchandising of mission patches, from the traditional sew on badge to T shirts. Do mission patches tell a story? Are they Art? What is the origin and role of this art form in society? The art form of space mission patches combines the 21st century relevance with heraldic origins predating the ninth century. The space mission patch is designed by the astronauts themselves if it is a manned mission. As an education tool teachers and educators use the space mission patch to engage their students in the excitement of space exploration, the mission patch design is utilized as an education tool in literature, science and art. The space mission patch is a particularly powerful message medium. This paper looks at the origins of the space mission patch, its relevance to art and its impact on society.
