    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.

  11. Expanding forensic science through forensic intelligence.

    Science.gov (United States)

    Ribaux, Olivier; Talbot Wright, Benjamin

    2014-12-01

    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.

  12. Internet and forensic science

    The Internet is a very powerful and inexpensive tool that was created for the free distribution of knowledge and information. The Internet is a learning tool, a research tool, a virtual library without borders and membership requirements, a journal with instant publication, a help desk, and a newspaper/journal with current information. Very soon, when live audio and video transmission is perfected, the Internet also will be a live classroom and everyday conference. Forensic scientists, laboratories and colleges should make use of information already available on the Internet. They also should actively participate and contribute. Very few forensic scientists and laboratories have made their presence felt by setting up their home pages/web pages. But, there is tremendous growth during the past year. Immense benefits from Internet to forensic community are discussed along with the author's personal experience. Creating on-line searchable data bases in all specialties of forensic science is an urgent need. Leading forensic journals should take a lead and create on-line searchable indexes with abstracts. On line electronic publishing, collaborative research/paper publishing or editing is easy, fast, economical and convenient through the use of the Internet. Creation of Internet repositories of unpublished papers is an idea worth looking into. Internet also can be used to give training, re-training or advanced training to students/forensic scientists.

NAUSS strives to improve the academic and professional skills of forensic scientists and security personnel to combat crime and terrorism by utilizing all the available tools of modern technology. NAUSS also realizes the importance of scientific research in the social, economic, and technological development of a society and is, therefore, committed to encouraging and supporting research at every level. NAUSS has given the fields of forensic sciences and forensic medicine a top priority and the attention they deserve. In pursuit of its objectives, and in cooperation with other Arab member organizations, NAUSS launched the Arab Society for Forensic Sciences and Forensic Medicine (ASFSFM in 2013. The Society had the honour of being officially launched by His Royal Highness, Prince Mohammed bin Naif bin Abdul Aziz, Crown Prince, Deputy Prime Minister and the Minister of the Interior, Honorary President of the Council of Arab Ministers of Interior and Chairman of the Supreme Council of NAUSS. The 2nd Arab Forensic Science & Forensic Medicine Meeting (ASFSFM Meeting 2016 was yet another part of the efforts and concern of NAUSS to advance the skills and knowledge of Arab specialists and to facilitate cooperation among forensic scientists and institutions engaged in the practice, education and research of forensic sciences and forensic medicine at various levels.

  14. Nanoparticles in forensic science

    Science.gov (United States)

    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.

  15. 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.

This paper summarizes the literature in forensic science management generally from 2009 to 2013, with some recent additions, to provide an overview of the growth of topics, results, and improvements in the management of forensic services in the public and private sectors. This review covers only the last three years or so and a version of this paper was originally produced for the 2013 Interpol Forensic Science Managers Symposium and is available at interpol.int.

  2. 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.

  3. Peer review in forensic science.

    Science.gov (United States)

    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.

  4. 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.

    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.

  10. Accreditation standards for undergraduate forensic science programs

    Science.gov (United States)

    Miller, Marilyn Tebbs

    Undergraduate forensic science programs are experiencing unprecedented growth in numbers of programs offered and, as a result, student enrollments are increasing. Currently, however, these programs are not subject to professional specialized accreditation. This study sought to identify desirable student outcome measures for undergraduate forensic science programs that should be incorporated into such an accreditation process. To determine desirable student outcomes, three types of data were collected and analyzed. All the existing undergraduate forensic science programs in the United States were examined with regard to the input measures of degree requirements and curriculum content, and for the output measures of mission statements and student competencies. Accreditation procedures and guidelines for three other science-based disciplines, computer science, dietetics, and nursing, were examined to provide guidance on accreditation processes for forensic science education programs. Expert opinion on outcomes for program graduates was solicited from the major stakeholders of undergraduate forensic science programs-forensic science educators, crime laboratory directors, and recent graduates. Opinions were gathered by using a structured Internet-based survey; the total response rate was 48%. Examination of the existing undergraduate forensic science programs revealed that these programs do not use outcome measures. Of the accreditation processes for other science-based programs, nursing education provided the best model for forensic science education, due primarily to the balance between the generality and the specificity of the outcome measures. From the analysis of the questionnaire data, preliminary student outcomes, both general and discipline-specific, suitable for use in the accreditation of undergraduate forensic science programs were determined. The preliminary results were reviewed by a panel of experts and, based on their recommendations, the outcomes

  12. 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.

  16. 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.

  17. Error and its meaning in forensic science.

    Science.gov (United States)

    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.

  18. An Improved Forensic Science Information Search.

    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.

    van den Hout, Ardo; Alberink, Ivo

    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.

    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.

  5. Forensic historiography: narratives and science.

    Science.gov (United States)

    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.

    "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

    The need for documented procedures and protocols are important in every specialist group to ensure a consistent service to the community. They provide guidance to members of the specialist group about responsibilities and appropriate practices, and confidence to the community that the services are of the highest possible standard. In a Disaster Victim Identification (DVI) incident, by enabling the process to be audited, they also serve to ensure that identifications are reliable. Following the Bali Bombings of 2002 and the 2004 Asian Tsunami the Australian Society of Forensic Odontology recognised the need for a practice guide to assist the management of their members in DVI incidents. 31 members of the Australian Society of Forensic Odontology participated in the development of a guideline document for Disaster Victim Identification using a Delphi based model. The advantage of using the iterative Delphi process is that it encouraged participants to think about the processes used in the forensic odontology aspects of a DVI incident and their expectations of a guiding document. The document developed as a result of this project is comprehensive in coverage and places the Australian Society of Forensic Odontology at the vanguard of professionalism in the forensic odontology and DVI community.

    We developed an education module on nuclear forensics, designed for high school science classrooms. The lessons include a mix of hands-on activities, computer simulations, and written exercises. Students are presented with realistic scenarios designed to develop their knowledge of nuclear science and its application to nuclear forensics. A two-day teacher workshop offered at Hope College attracted 20 teachers. They were loaned kits to implement activities with their students, and each teacher spent 3--7 days on the lessons. All who reported back said they would do it again and would share the lessons with colleagues. Many said that access to equipment and ready-made lessons enabled them to expand what they taught about nuclear science and introduce nuclear forensics. A few teachers invited guest speakers to their classroom, which provided an excellent opportunity to share career information with students. We acknowledge generous support from the Department of Homeland Security and the AIP Meggars Award.

  12. Paradigms of forensic science and legal process: a critical diagnosis.

    Roberts, Paul

    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.

  18. Molecular forensic science analysis of nuclear materials

    Science.gov (United States)

    Reilly, Dallas David

    Concerns over the proliferation and instances of nuclear material in the environment have increased interest in the expansion of nuclear forensics analysis and attribution programs. A new related field, molecular forensic science (MFS) has helped meet this expansion by applying common scientific analyses to nuclear forensics scenarios. In this work, MFS was applied to three scenarios related to nuclear forensics analysis. In the first, uranium dioxide was synthesized and aged at four sets of static environmental conditions and studied for changes in chemical speciation. The second highlighted the importance of bulk versus particle characterizations by analyzing a heterogeneous industrially prepared sample with similar techniques. In the third, mixed uranium/plutonium hot particles were collected from the McGuire Air Force Base BOMARC Site and analyzed for chemical speciation and elemental surface composition. This work has identified new signatures and has indicated unexpected chemical behavior under various conditions. These findings have lead to an expansion of basic actinide understanding, proof of MFS as a tool for nuclear forensic science, and new areas for expansion in these fields.

    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.

    2002-06-01

    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.

    2015-08-05

    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.

    The utility of short tandem repeat genetic (STR) markers for forensic science is beyond question and there are over 50 million STR profiles in current national databases. The magnitude and value of those data, however, are likely to be dwarfed by what is emerging from large-scale SNP and DNA sequence assays. Phenotypic characterization may well accompany future statements about identity. In this very brief review we focus on the use of rare variants to describe relatedness and population structure.

    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.

  17. Forensics, radiology, society. X-rays. Tool and document

    Energy Technology Data Exchange (ETDEWEB)

    Vogel, Beatrice; Vogel, Hermann [Hamburg Univ. (Germany). Inst. of Forensic Medicine

    2014-07-01

    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.

    Tettey, Justice; Crean, Conor

    2015-08-01

    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.

  8. The future of forensic and crime scene science. Part II. A UK perspective on forensic science education.

    2006-03-14

    This paper builds on the views presented by the author at 'The Future of Forensic and Crime Scene Science Conference'. Forensic science has become an increasingly prominent area of science within the last 10 years. This increasing prominence together with popularity in the subject has seen the number of undergraduate students studying forensic science related courses at UK Universities increase rapidly in just 5 years and there are no short term signs of this trend reducing. In 2005, there were 450 courses with forensic in the title offered by higher education institutes. Although the forensic community has expressed its concern that job prospects for these students wishing to pursue careers as forensic scientists will be limited numbers of students undertaking science courses have still increased. The increase in students studying forensic science comes in an era of decreasing science numbers in higher education with the potential to produce high calibre science graduates with sought after skills in critical thinking, analysis, interpretation and communication. Technology has continued to advance at a similar pace providing those responsible for managing crime with a need and opportunity to identify and predict new and future applications of science and technology; not just in reducing and detecting crime but also in predicting how technology will be used by criminals in the future. There is therefore a need for forensic science users, providers and educators to identify the knowledge and skills required by forensic scientists and crime investigators of the future to ensure that technology continues to be used and applied to its full advantage. This provides universities an opportunity to contribute to the development of both the practice and practitioners of forensic science. This paper outlines the current issues facing universities in relation to forensic science and identifies their future role in providing high quality relevant courses for future forensic

    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

    2006-01-27

    The debate in forensic science concentrates on issues such as standardisation, accreditation and de-contextualisation, in a legal and economical context, in order to ensure the scientific objectivity and efficiency that must guide the process of collecting, analysing, interpreting and reporting forensic evidence. At the same time, it is recognised that forensic case data is still poorly integrated into the investigation and the crime analysis process, despite evidence of its great potential in various situations and studies. A change of attitude is needed in order to accept an extended role for forensic science that goes beyond the production of evidence for the court. To stimulate and guide this development, a long-term intensive modelling activity of the investigative and crime analysis process that crosses the boundaries of different disciplines has been initiated. A framework that fully integrates forensic case data shows through examples the capital accumulated that may be put to use systematically.

  13. Analysis of errors in forensic science

    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.

    Epigenetics is the study of heritable changes in gene expression other than changes in the underlying DNA sequence. Such changes include DNA methylation, histone modification, chromatin remodeling, genomic imprinting, X chromosome inactivation and non-coding RNA regulation. Recent progresses on epigenetics open new possibilities in tackling these challenging problems in forensic science, including identification of fetal paternity testing in embryonic period, determination of the necessary allele in paternity testing, discrimination of identical twins, origination analysis of micro tissue, verification of forged DNA. This review focuses on epigenetics concept and its latest application in the field of paternity testing, age estimation, discrimination between the twins, identification of tissue of origin, and estimation of postmortem interval.

    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? These and related questions are addressed from a wide range of areas in order to be inclusive, as well as to demonstrate similarities across areas. Likewise, in order to be culturally comparative, this volume includes examples and discussions of experts in different countries and even in different time periods. The topics include the r...

    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.

  1. 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

    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.

    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.

    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.

    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.

    The Internet has become a very powerful and inexpensive tool for the free distribution of knowledge and information. It is a learning and research tool, a virtual library without borders and membership requirements, a help desk, and a publication house providing newspapers with current information and journals with instant publication. Very soon, when live audio and video transmission is perfected, the Internet (popularly referred to as the Net) also will be a live classroom and everyday conference site. This article provides a brief overview of the basic structure and essential components of the Internet. A limited number of home pages/Web sites that are already made available on the Net by scientists, laboratories, and colleges in the forensic science community are presented in table forms. Home pages/Web sites containing useful information pertinent to different disciplines of forensic science are also categorized in various tables. The ease and benefits of the Internet use are exemplified by the author's personal experience. Currently, only a few forensic scientists and institutions have made their presence felt. More participation and active contribution and the creation of on-line searchable databases in all specialties of forensic science are urgently needed. Leading forensic journals should take the lead and create on-line searchable indexes with abstracts. Creating Internet repositories of unpublished papers is an idea worth looking into. Leading forensic science institutions should also develop use of the Net to provide training and retraining opportunities for forensic scientists.

    2008-12-01

    The scientific literature contains very little about the role of the dental hygienist/therapist in the specific areas of forensic investigations and collection of evidence. The authors examine how the contribution of a highly qualified dental hygienist can be particularly helpful during human forensic identification operations and non-accidental traumas like domestic violence, child abuse, neglect and bitemarks. Forensic dental identification of human remains is a highly complex multidisciplinary challenge. It requires the involvement of several professionals who are expert in forensic science. Among these, one or more adequately trained dental hygienists could be involved. Dental hygienists/therapists may also be asked to record cutaneous lesions in two different situations. The first may be the dental office where she/he may detect oval, elliptic, or semicircular lesions on the skin of the uncovered neck, shoulder and arms of a patient. The second is the crime scene or the morgue (if one is involved), which may require a visit by the forensic odontologist called by the medical examiner or the coroner to perform an odontological autopsy. The purpose of our study is to highlight procedures that should be followed by the dental hygienist/therapist in collecting forensic information in the above-mentioned scenarios. As a valuable resource, the authors recommend training of dental hygienists in the area of forensic sciences, with particular attention to information technology and photography.

    Next-generation sequencing (NGS) technology, with its high-throughput capacity and low cost, has developed rapidly in recent years and become an important analytical tool for many genomics researchers. New opportunities in the research domain of the forensic studies emerge by harnessing the power of NGS technology, which can be applied to simultaneously analyzing multiple loci of forensic interest in different genetic contexts, such as autosomes, mitochondrial and sex chromosomes. Furthermore, NGS technology can also have potential applications in many other aspects of research. These include DNA database construction, ancestry and phenotypic inference, monozygotic twin studies, body fluid and species identification, and forensic animal, plant and microbiological analyses. Here we review the application of NGS technology in the field of forensic science with the aim of providing a reference for future forensics studies and practice.

    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.

    2014-01-01

    Next-generation sequencing (NGS) technology, with its high-throughput capacity and low cost, has developed rapidly in recent years and become an important analytical tool for many genomics researchers. New opportunities in the research domain of the forensic studies emerge by harnessing the power of NGS technology, which can be applied to simultaneously analyzing multi-ple loci of forensic interest in different genetic contexts, such as autosomes, mitochondrial and sex chromosomes. Furthermore, NGS technology can also have potential applications in many other aspects of research. These include DNA database construction, ancestry and phenotypic inference, monozygotic twin studies, body fluid and species identification, and forensic animal, plant and microbiological analyses. Here we review the application of NGS technology in the field of forensic science with the aim of providing a reference for future forensics studies and practice.

    Forensic science is already taking benefits from synchrotron radiation (SR) sources in trace evidence analysis. In this contribution we show a multi-technique approach to study fingerprints from the morphological and chemical point of view using SR based techniques such as Fourier transform infrared microspectroscopy (FTIRMS), X-ray fluorescence (XRF), X-ray absorption structure (XAS), and phase contrast microradiography. Both uncontaminated and gunshot residue contaminated human fingerprints were deposited on lightly doped silicon wafers and on poly-ethylene-terephthalate foils. For the uncontaminated fingerprints an univariate approach of functional groups mapping to model FT-IRMS data was used to get the morphology and the organic compounds map. For the gunshot residue contaminated fingerprints, after a preliminary elemental analysis using XRF, microradiography just below and above the absorption edge of the elements of interest has been used to map the contaminants within the fingerprint. Finally, XAS allowed us to determine the chemical state of the different elements. The next step will be fusing the above information in order to produce an exhaustive and easily understandable evidence.

  18. Forensic science, genetics and wildlife biology: getting the right mix for a wildlife DNA forensics lab.

    Science.gov (United States)

    Ogden, Rob

    2010-09-01

    Wildlife DNA forensics is receiving increasing coverage in the popular press and has begun to appear in the scientific literature in relation to several different fields. Recognized as an applied subject, it rests on top of very diverse scientific pillars ranging from biochemistry through to evolutionary genetics, all embedded within the context of modern forensic science. This breadth of scope, combined with typically limited resources, has often left wildlife DNA forensics hanging precariously between human DNA forensics and academics keen to seek novel applications for biological research. How best to bridge this gap is a matter for regular debate among the relatively few full-time practitioners in the field. The decisions involved in establishing forensic genetic services to investigate wildlife crime can be complex, particularly where crimes involve a wide range of species and evidential questions. This paper examines some of the issues relevant to setting up a wildlife DNA forensics laboratory based on experiences of working in this area over the past 7 years. It includes a discussion of various models for operating individual laboratories as well as options for organizing forensic testing at higher national and international levels.

  19. Nature and place of crime scene management within forensic sciences.

    Science.gov (United States)

    Crispino, Frank

    2008-03-01

    This short paper presents the preliminary results of a recent study aimed at appreciating the relevant parameters required to qualify forensic science as a science through an epistemological analysis. The reader is invited to reflect upon references within a historical and logical framework which assert that forensic science is based upon two fundamental principles (those of Locard and Kirk). The basis of the assertion that forensic science is indeed a science should be appreciated not only on one epistemological criteria (as Popper's falsification raised by the Daubert hearing was), but also on the logical frameworks used by the individuals involved (investigator, expert witness and trier of fact) from the crime scene examination to the final interpretation of the evidence. Hence, it can be argued that the management of the crime scene should be integrated into the scientific way of thinking rather than remain as a technical discipline as recently suggested by Harrison.

    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.

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

    Science.gov (United States)

    Drake, Stacy A; Langford, Rae; Young, Anne; Ayers, Constance

    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.

  10. Micro-RNA - A potential for forensic science?

    Science.gov (United States)

    Courts, Cornelius; Madea, Burkhard

    2010-12-15

    Micro-RNAs (miRNAs) are a class of small non-coding RNA (ncRNA) molecules with a length of 18 to 24 nucleotides which play an essential regulative role for many cellular processes. Whereas mRNA-analysis has become a well established technique in many forensic laboratories, micro-RNA has only recently been introduced to forensic science. Herein we provide a short outline of biogenesis, mode of function and regulation of miRNAs and take a look at tissue and cell specific miRNA expression. After recapitulating the role of mRNA analysis in forensic science we compare it to miRNA analysis and discuss the results of two recent studies applying miRNA analysis to a forensic research setting. We conclude that analysis of miRNA and perhaps small non-coding RNAs in general clearly has potential for forensic applications and merits attention of forensic scientists.

    2010-11-01

    Dentistry has much to offer law enforcement in the detection and solution of crime or in civil proceedings. Forensic dental fieldwork requires an interdisciplinary knowledge of dental science and forensic science. Most often the role of the forensic odontologist is to establish a person's identity. Teeth, with their physiologic variations, pathoses and effects of therapy, record information that remains throughout life and beyond. The teeth may also be used as weapons and, under certain circumstances, may leave information about the identity of the culprit. Forensic odontology has an important role in the recognition of abuse among persons of all ages. Dental professionals have a major role to play in keeping accurate dental records and providing all necessary information so that legal authorities may recognise malpractice, negligence, fraud or abuse, and identify unknown human. Forensic odontology involves the management, examination, evaluation and presentation of dental evidence in criminal or civil proceedings, all in the interest of justice. The forensic odontologist assists legal authorities by examining dental evidence in different situations.

  13. 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.

    Ewing, Andrew V; Kazarian, Sergei G

    2017-01-16

    Infrared spectroscopy and spectroscopic imaging, are robust, label free and inherently non-destructive methods with a high chemical specificity and sensitivity that are frequently employed in forensic science research and practices. This review aims to discuss the applications and recent developments of these methodologies in this field. Furthermore, the use of recently emerged Fourier transform infrared (FT-IR) spectroscopic imaging in transmission, external reflection and Attenuated Total Reflection (ATR) modes are summarised with relevance and potential for forensic science applications. This spectroscopic imaging approach provides the opportunity to obtain the chemical composition of fingermarks and information about possible contaminants deposited at a crime scene. Research that demonstrates the great potential of these techniques for analysis of fingerprint residues, explosive materials and counterfeit drugs will be reviewed. The implications of this research for the examination of different materials are considered, along with an outlook of possible future research avenues for the application of vibrational spectroscopic methods to the analysis of forensic samples.

  16. 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.

    Acts of terrorism, an increase in the use of firearms, drug abuse, the use of so-called date-rape drugs, and driving whilst under the influence of drugs, are just some of the subjects frequently in the news. In the absence of fingermarks and of material leading to the recovery of DNA, the forensic scientist has to rely upon chemical analysis of trace amounts of materials including explosives, drugs, toxicological specimens, firearms discharge residues, fibres, glass, paint, soil etc., in order to establish or eliminate links between suspect and victim and/or scene. This tutorial review describes analytical problems facing the forensic chemist, and the current methods and techniques employed to tackle them.

  18. Advancing the science of forensic data management

    Naughton, Timothy S.

    2002-07-01

    Many individual elements comprise a typical forensics process. Collecting evidence, analyzing it, and using results to draw conclusions are all mutually distinct endeavors. Different physical locations and personnel are involved, juxtaposed against an acute need for security and data integrity. Using digital technologies and the Internet's ubiquity, these diverse elements can be conjoined using digital data as the common element. This result is a new data management process that can be applied to serve all elements of the community. The first step is recognition of a forensics lifecycle. Evidence gathering, analysis, storage, and use in legal proceedings are actually just distinct parts of a single end-to-end process, and thus, it is hypothesized that a single data system that can also accommodate each constituent phase using common network and security protocols. This paper introduces the idea of web-based Central Data Repository. Its cornerstone is anywhere, anytime Internet upload, viewing, and report distribution. Archives exist indefinitely after being created, and high-strength security and encryption protect data and ensure subsequent case file additions do not violate chain-of-custody or other handling provisions. Several legal precedents have been established for using digital information in courts of law, and in fact, effective prosecution of cyber crimes absolutely relies on its use. An example is a US Department of Agriculture division's use of digital images to back up its inspection process, with pictures and information retained on secure servers to enforce the Perishable Agricultural Commodities Act. Forensics is a cumulative process. Secure, web-based data management solutions, such as the Central Data Repository postulated here, can support each process step. Logically marrying digital technologies with Internet accessibility should help nurture a thought process to explore alternatives that make forensics data accessible to authorized individuals

    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.

    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.

    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.

    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.

  10. 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.

    Full Text Available The fundamental base underlying scientific empirical principles is currently at high risk of collapse or extinction. Under threat from pseudo-science and technologies which are advancing faster than philosophies can accompany them, and in a grey zone of masqueraded ethical principles, the schools of thought that were once thought to be the omnipotent cornerstones of the scientific institute of knowledge are now doomed to become historical relics. Increasing polarisation of rich versus poor, subsidised versus not, Impact Factor vs non-Impact Factor, paid-view versus open access, and a whole host of other conflicting concepts is further dividing the elite minority of the global scientific community from its silenced majority. Awareness constitutes the first step on the road to constructive change. Shrouded in quasi-ignorance, scientists from Beijing to Belfast are fast being locked in a cycle that may revolutionise the world of science as we know it, blindly, but not painlessly. This small opinion paper is meant to be a nutcracker of sorts intended to initiate a cascade of counter-measures to stem the inevitable tide.

    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.

    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...

  14. Enhancing forensic science with spectroscopic imaging

    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

  16. The logical foundations of forensic science: towards reliable knowledge.

    Science.gov (United States)

    Evett, Ian

    2015-08-01

    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.

    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.

  5. Forensic identification science evidence since Daubert: Part I--A quantitative analysis of the exclusion of forensic identification science evidence.

    Page, Mark; Taylor, Jane; Blenkin, Matt

    2011-09-01

    The U.S. Supreme Court decisions in Daubert v. Merrell Dow Pharmaceuticals Inc. and Kumho Tire Co. Ltd. v. Carmichael transformed the way scientific expert evidence was reviewed in courts across the United States. To gauge the impact of these rulings on the admission of forensic identification evidence, the authors analyzed 548 judicial opinions from cases where admission of such evidence was challenged. Eighty-one cases (15%) involved exclusion or limitation of identification evidence, with 50 (65.7%) of these failing to meet the "reliability" threshold. This was largely because of a failure to demonstrate a sufficient scientific foundation for either the technique (27 cases) or the expert's conclusions (17 cases). The incidence of exclusion/limitation because of a lack of demonstrable reliability suggests that there is a continuing need for the forensic sciences to pursue research validating their underlying theories and techniques of identification to ensure their continued acceptance by the courts.

    @@ Sport is probably the most ubiquitous voluntary human social activity. Defined as the playing of competitive games according to rules, sport forms a microcosm of human society that combines playfulness ("homo ludens"),healthfulness, competitiveness and showiness into a rich amalgam that illustrates the best and worst (with much in between) about organized human social activities. It ranges widely to celebrate achievement in fame and fortune through competitive success and co-operative efforts, to foster socialization by the bonding experiences of team-spirit in childhood and youth, to providing the most popular mass entertainment and to create vignettes of the worst excesses of human avarice, cheating and violence. Sport also ranges from the lows of defeat and disappointment, to the highs of a "personal best" that is within anyone's reach and to the most profound accomplishments of world records; from the most solitary of personal struggles to the most public of popular entertainment. A modern version of Shakespeare's "all the world's a stage" might nowadays be recast more widely as "all the world's a stadium".

    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.

    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.

    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.

    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.

    Interdisciplinary scientific knowledge is necessary but not sufficient when it comes to addressing sustainable transformations, as science increasingly has to deal with normative and value-related issues. A systems perspective on coupled human-environmental systems (HES) helps to address the inherent complexities. Additionally, a thorough interaction between science and society (i.e., transdisciplinarity = TD) is necessary, as sustainable transitions are sometimes contested and can cause conflicts. In order to navigate complexities regarding the delicate interaction of scientific research with societal decisions these processes must proceed in a structured and functional way. We thus propose HES-based TD processes to provide a basis for reorganizing science in coming decades.

    Full Text Available Introduction: Personal identification is becoming increasingly important not only in legal medicine but also in crime/criminal investigation and identification. Sometimes establishing a person's identity can be a very difficult process. Dental, fingerprint, and DNA comparisons are probably the most common technique used. However, there are many well-known implanted methods of human identification, one of the most interesting emerging methods of human identification which originates from the criminal and forensic practice, is human lips recognition. Cheiloscopy is a forensic investigation technique that deals with the identification based on lip traces. The lip outline of every person is unique and can be used to fix the personal identity. Aim: The aim of this study was to assess the distribution of lip outline patterns among males and females, and to evaluate the uniqueness of lip outline pattern. Materials and Methods: The study group comprised of 200 individuals from Kamineni Institute of Dental Sciences. Lip outline patterns were obtained and were transferred to the proforma sheet for analysis. Results: The results of the study revealed that the lip outline patterns for each individual were unique. Conclusion: This study showed that lip outline patterns are unique to each individual and can be used for personal identification.

    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.

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.

  11. The Role of Science in Our Society

    Energy Technology Data Exchange (ETDEWEB)

    2002-07-10

    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.

    Predecessor of todays Estonian Soil Science Society was Estonian Branch of All-Union Soil Society of Soil Scientist which acted from 1957 to 1991. In 1957-1964 Estonian Branch was leaded by prof. Osvald Hallik and in 1964-1991 by prof. Loit Reintam. After re-independence of Estonia in 1991 the society acted in informal way and was leaded by prof. L. Reintam. Non-profit organization "Estonian Soil Science Society" was officially (re)established in 10.23.2009. Estonian Soil Science Society (ESSS) is aimed to: • coordinate collaboration between institutions and individuals intrested of soil science, conservation and sustainable use of soils; • promoting soil science education and research, raising awareness of publicity on topics relating to soils in Estonia; • cooperation between local and foreign unions and associations. In recent years the ESSS had managed to reunite the number of soil scientist from different research institutions of Estonia and of related institutions. Also, the ESSS had provided numerous of materials based on later scientific findings. One of most important activity leaded by ESSS is the organizing Soil Day in Estonia with relevant seminar, where the speakers are sharing latest information with target group (researchers, teachers, policy makers, farmers, students etc.). In a frames of Soil Day the Soil of the Year is selected for Estonia. In 2015, the soil of the year is Leptosol. For current, International Year of the Soil ESSS had planned numerous activities to introduce the importance of soils to wider audience. In current presentation we would like to share the soil science researchers experience through- out the decades of soil science research in Estonia, show our latest findings and designed activities for the International Year of SOIL.

    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.

    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

    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.

    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.

  17. PREFACE: John Desmond Bernal: Science and Society

    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

    Forensic odontology nowadays has become a developing science and is of great importance to society. It is important that dental practitioners should have a proper knowledge of forensics as the need has increased greatly over the last decades due to the unprecedented demand from the criminal justice including terrorism in Kashmir valley (J&K India). Data was collected based on questionnaire survey among qualified dental practitioners related to their awareness of forensic odontology. A total number of 235 dental practitioners responded to the questionnaire. RESULTS showed that there was a low confidence, in handling of forensic odontology related cases among dental practitioners and majority of dental practitioners were not having any formal training in forensic odontology. Each dental practitioner has a responsibility to understand the forensic implications associated with the practice of his profession and thus he should work sincerely enough so to ensure his contribution in the field of forensic odontology.

  1. Forensic identification science evidence since Daubert: Part II--judicial reasoning in decisions to exclude forensic identification evidence on grounds of reliability.

    Page, Mark; Taylor, Jane; Blenkin, Matt

    2011-07-01

    Many studies regarding the legal status of forensic science have relied on the U.S. Supreme Court's mandate in Daubert v. Merrell Dow Pharmaceuticals Inc., and its progeny in order to make subsequent recommendations or rebuttals. This paper focuses on a more pragmatic approach to analyzing forensic science's immediate deficiencies by considering a qualitative analysis of actual judicial reasoning where forensic identification evidence has been excluded on reliability grounds since the Daubert precedent. Reliance on general acceptance is becoming insufficient as proof of the admissibility of forensic evidence. The citation of unfounded statistics, error rates and certainties, a failure to document the analytical process or follow standardized procedures, and the existence of observe bias represent some of the concerns that have lead to the exclusion or limitation of forensic identification evidence. Analysis of these reasons may serve to refocus forensic practitioners' testimony, resources, and research toward rectifying shortfalls in these areas.

    We revisit a series of papers on science and society issues by David Hafemeister in the 1970s and 1980s. The emphasis in the present work is on world oil production limits and some consequences of various possible scenarios for the near future. Some of the data and scenarios used by Hafemeister are updated for U.S. oil production in the past two decades, and extended to an analysis of a peak in world oil production in the future. We discuss some simple scenarios for future energy use patterns and look at the consequence of these scenarios as world oil production begins to decline. We also provide a list of resources for critical investigations of natural resource extraction and depletion patterns.

    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.

  6. Students' conceptions of evidence during a university introductory forensic science course

    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

    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.

    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...

    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’.

    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.

    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.

    Discrimination of material based on elemental composition was achieved within a compositional data (CoDa) analysis framework in a form appropriate for use in forensic science. The methods were carried out on example data from New Zealand nephrite. We have achieved good separation of the in situ outcrops of nephrite from within a well-defined area. The most significant achievement of working within the CoDa analysis framework is that the implications of the constraints on the data are acknowledged and dealt with, not ignored. The full composition was reduced based on collinearity of elements, principal components analysis (PCA) and scalings from a backwards linear discriminant analysis (LDA). Thus, a descriptive subcomposition was used for the final discrimination, using LDA, and proved to be more successful than using the full composition. The classification based on the LDA model showed a mean error rate of 2.9% when validated using a 10 repeat, three-fold cross-validation. The methods presented lend objectivity to the process of interpretation, rather than relying on subjective pattern matching type approaches.

  15. Psychological processes and paranoia: implications for forensic behavioural science.

    2006-01-01

    Paranoid delusions have recently become the focus of empirical research. In this article, we review studies of the psychological mechanisms that might be involved in paranoid thinking and discuss their implications for forensic behaviour science. Paranoia has not been consistently associated with any specific neuropsychological abnormality. However, evidence supports three broad types of mechanism that might be involved in delusional thinking in general and paranoia in particular: anomalous perceptual experiences, abnormal reasoning, and motivational factors. There is some evidence that paranoia may be associated with hearing loss, and good evidence that paranoid patients attend excessively to threatening information. Although general reasoning ability seems to be unaffected, there is strong evidence that a jumping- to-conclusions style of reasoning about data is implicated in delusions in general, but less consistent evidence specifically linking paranoia to impaired theory of mind. Finally, there appears to be a strong association between paranoia and negative self-esteem, and some evidence that attempts to protect self-esteem by attributing negative events to external causes are implicated. Some of these processes have recently been implicated in violent behaviour, and they therefore have the potential to explain the apparent association between paranoid delusions and offending.

    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.

  1. Emergence of forensic podiatry--A novel sub-discipline of forensic sciences.

    "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

    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.

    Stojer, Joanna

    2011-01-01

    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.

    2015-05-01

    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.

    2015-06-01

    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.

  2. Integrating forensic science into nursing processes in the ICU.

    Hoyt, Constance A

    2006-01-01

    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.

  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.

    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.

    Eastwood, Joseph; Caldwell, Jiana

    2015-11-01

    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.

    2016-11-01

    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.

  14. 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.

    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.

    Full Text Available In the field of science, Central and East European countries (CEECs have inherited various relics from the past, among them: -bad communication between science and society, -low level of public understanding of science (PUS, -weak co-operation between the science sphere and the production sphere, -small scale of science commercialisation, -practically non-existent infrastructure of scientific and technological knowledge flows in society. At present, the market reforms in CEECs are far advanced. So now, the main direction in their developments is to build the knowledge-based economy/society. Moreover, the science sector has been divided into three separate sub-sectors: (1 Higher Education, (2 Academies of Sciences and (3 Industrial R&D. Higher education institutions together with academy of sciences¿ research institutes constitute so-called academic science. In reforming our countries towards modern market economies, academic science faces numerous challenges. Among them, there is a challenge: How to communicate better with society? There are various tools of such communication. One of them is public relations (PR. The main aim of this paper is to prove a big potential role of public relations as a communication tool between academic science and society, with a special reference to CEECs. Poland will here be a case-study. The following issues will be analyzed in the paper: 1. The role of science communication: A brief survey of literature 2.

    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.

    2008-09-18

    Non-invasive documentation methods such as surface scanning and radiological imaging are gaining in importance in the forensic field. These three-dimensional technologies provide digital 3D data, which are processed and handled in the computer. However, the sense of touch gets lost using the virtual approach. The haptic device enables the use of the sense of touch to handle and feel digital 3D data. The multifunctional application of a haptic device for forensic approaches is evaluated and illustrated in three different cases: the representation of bone fractures of the lower extremities, by traffic accidents, in a non-invasive manner; the comparison of bone injuries with the presumed injury-inflicting instrument; and in a gunshot case, the identification of the gun by the muzzle imprint, and the reconstruction of the holding position of the gun. The 3D models of the bones are generated from the Computed Tomography (CT) images. The 3D models of the exterior injuries, the injury-inflicting tools and the bone injuries, where a higher resolution is necessary, are created by the optical surface scan. The haptic device is used in combination with the software FreeForm Modelling Plus for touching the surface of the 3D models to feel the minute injuries and the surface of tools, to reposition displaced bone parts and to compare an injury-causing instrument with an injury. The repositioning of 3D models in a reconstruction is easier, faster and more precisely executed by means of using the sense of touch and with the user-friendly movement in the 3D space. For representation purposes, the fracture lines of bones are coloured. This work demonstrates that the haptic device is a suitable and efficient application in forensic science. The haptic device offers a new way in the handling of digital data in the virtual 3D space.

  9. Science, society, and the coastal groundwater squeeze

    Science.gov (United States)

    Michael, Holly A.; Post, Vincent E. A.; Wilson, Alicia M.; Werner, Adrian D.

    2017-04-01

    Coastal zones encompass the complex interface between land and sea. Understanding how water and solutes move within and across this interface is essential for managing resources for society. The increasingly dense human occupation of coastal zones disrupts natural groundwater flow patterns and degrades freshwater resources by both overuse and pollution. This pressure results in a "coastal groundwater squeeze," where the thin veneers of potable freshwater are threatened by contaminant sources at the land surface and saline groundwater at depth. Scientific advances in the field of coastal hydrogeology have enabled responsible management of water resources and protection of important ecosystems. To address the problems of the future, we must continue to make scientific advances, and groundwater hydrology needs to be firmly embedded in integrated coastal zone management. This will require interdisciplinary scientific collaboration, open communication between scientists and the public, and strong partnerships with policymakers.

    2014-01-01

    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.

  12. 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.

    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 was gathered over one course (one semester). We 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 experiences they have during this course are crucial for developing worldviews that incorporate positive ideas about the role of science in society.

    The Vision and Change in Undergraduate Biology Education reports cite the critical role of professional societies in undergraduate life science education and, since 2008, have called for the increased involvement of professional societies in support of undergraduate education. Our study explored the level of support being provided by societies for undergraduate education and documented changes in support during the Vision and Change era. Society representatives responded to a survey on programs, awards, meetings, membership, teaching resources, publications, staffing, finances, evaluation, and collaborations that address undergraduate faculty and students. A longitudinal comparison group of societies responded to surveys in both 2008 and 2014. Results indicate that life science professional societies are extensively engaged in undergraduate education in their fields, setting standards for their discipline, providing vetted education resources, engaging students in both research and education, and enhancing professional development and recognition/status for educators. Societies are devoting funding and staff to these efforts and engaging volunteer leadership. Longitudinal comparison group responses indicate there have been significant and quantifiable expansions of undergraduate efforts in many areas since 2008. These indicators can serve as a baseline for defining, aligning, and measuring how professional societies can promote sustainable, evidence-based support of undergraduate education initiatives.

    Quantitative phase analysis (QPA) is helpful to determine the type attribute of the object because it could present the content of the constituents. QPA by Rietveld method requires neither measurement of calibration data nor the use of an internal standard; however, the approximate crystal structure of each phase in a mixture is necessary. In this study, 8 synthetic mixtures composed of potassium nitrate and sulfur were analyzed by Rietveld QPA method. The Rietveld refinement was accomplished with a material analysis using diffraction program and evaluated by three agreement indices. Results showed that Rietveld QPA yielded precise results, with errors generally less than 2.0% absolute. In addition, a criminal case which was broken successfully with the help of Rietveld QPA method was also introduced. This method will allow forensic investigators to acquire detailed information of the material evidence, which could point out the direction for case detection and court proceedings.

  1. Student achievement and perceptions: The effects of a forensic science curriculum

    Science.gov (United States)

    Noga, Lisa L.

    The purpose and primary research question of this two-phase, sequential, mixed-methods study was to explore the relationship between a forensic-based curriculum and how it affected student achievement and the impact the curriculum had on student perceptions about science. Science teachers have the challenging task to sustain student enthusiasm while increasing science achievement. Results of this study could be utilized by science educators seeking to design a hands-on curriculum. Sixty sixth-grade students in a Georgia middle school were engaged in this 4-week study. The qualitative data were transcribed and analyzed using open coding. Common themes were created from the data inductively when coded data were merged together according to topic. Based on data collected from interviews and observations, students demonstrated a positive change in perception of science after exposure to a forensics curriculum. Each student completed a pretest and posttest and results were analyzed using descriptive statistics. Results indicated a 26.5% increase between the mean of the students' pretest and posttest scores. Inferential tests were not conducted for the quantitative data due to a small sample size. Implementing a mixed-methods study allowed the researcher to use multiple data sources and triangulate the data. The overall data analysis revealed that a forensic-based curriculum increased achievement and had a positive impact on student perceptions about science. Due to the escalating importance of science education, this study promoted social change in that it addressed strategies of best practices in teaching to positively affect student achievement and perceptions in science.

    Microbeam X-ray fluorescence (micro-XRF) spectrometry has been raised as an analytical technique of microbeam during the recent years. With its advantages of high sensitivity, small sample requirement, high testing accuracy and non-destruction, the technique is widely utilized in forensic science. This review bases on recent researches at home and abroad, describes its applications including identification of gunshot residue, visualization of fingerprints, discrimination of drug source, production process, and other material evidences of analysis in crime scene. Thanks to the advances in technology, intelligent and portable micro-XRF equipment has appeared to be applied. It is believed that it may be more popular and frequent in administration of forensic science in the near future.

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

    Science.gov (United States)

    Lucena-Molina, Jose-Juan; Pardo-Iranzo, Virginia; Gonzalez-Rodriguez, Joaquin

    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.

    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.

    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.

    Many researchers have been working in Spain to document the communal graves of those assassinated during the Spanish Civil War. This article shows the results obtained with two low-cost photogrammetric techniques for the basic documentation of forensic studies. These low-cost techniques are based on single-image rectification and the correction of the original photo displacement due to the projection and perspective distortions introduced by the lens of the camera. The capability of image rectification is tested in an excavation in the village of Loma de Montija (Burgos, Spain). The results of both techniques are compared with the more accurate data obtained from a laser scanner system RIEGL LMS-Z390i to evaluate the error in the lengths. The first technique uses a camera situated on a triangle-shaped pole at a height of 5 m and the second positions the camera over the grave using a linearly actuated device. The first technique shows measurement errors less than 6%, whereas the second shows greater errors (between 8% and 14%) owing to the positioning of the carbon-fiber cross on an uneven surface.

  9. Odontology as a forensic science, the North American experience.

    Science.gov (United States)

    Barsley, Robert E

    2010-09-10

    This chapter discusses the North American situation, primarily that of the United States judicial system. The United States was established as neither a monarchy nor a theocracy. An unofficial motto of the country has always been - the rule of laws, not of men (or deities). The primary source of law in the United States is the US Constitution. However, each of the 50 states has as its primary source of law a state constitution. In order to become a state, that constitution must conform to US Constitution. In the United States the US Congress, consisting of duly elected Representatives and Senators from the 50 states draft and pass Acts that establish (or direct to be established by officers of the Executive Branch following prescribed administrative procedures) federal law. Each state too, has its own legislative bodies and process for making law. Each state also has its own system of courts. In order to discuss the role of the odontologist within these systems, a primer on how these systems function and interact is crucial. This article discusses the functioning of those systems in relation to the practice of forensic odontology.

    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.

  11. 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

  12. Which articles and which topics in the forensic sciences are most highly cited?

    2005-01-01

    Forensic science is a multidisciplinary field, which covers many branches of the pure, the applied and the biomedical sciences. Writing-up and publishing research findings helps to enhance the reputation of the investigators and the laboratories where the work was done. The number of times an article is cited in the reference lists of other articles is generally accepted as a mark of distinction. Indeed, citation analysis has become widely used in research assessment of individual scientists, university departments and entire nations. This article concerns the most highly cited papers published in the Journal of Forensic Sciences (JFS) between 1956 and 2005. These were identified with the help of Web-of-Science, which is the on-line version of Science Citation Index, produced by Thomson Institute for Scientific Information (Thomson ISI) with head offices in Philadelphia, USA. This database tracks, among other things, the annual citation records of articles published in several thousand scientific journals worldwide. Those JFS articles accumulating 50 or more citations were identified and rank-ordered according to the total number of citations. These articles were also evaluated according to the name of first author, the subject category of the article, the country of origin and the pattern of co-authorship. This search strategy located 46 articles cited between 50 and 292 times since they first appeared in print. The most highly cited paper by far was by Kasai, Nakamura and White (USA and Japan) concerning DNA profiling and the application of the polymerase chain reaction (PCR) in forensic science. Some forensic scientists appeared as first author on two to three highly cited articles, namely Wetli (USA), Budowle (USA) and Comey (USA). When the highly cited articles were sub-divided into subject category, 15 were identified as coming from toxicology, closely followed by criminalistics (14 articles), pathology (nine articles), physical anthropology (five articles

Although work in all of these areas is important, it is the scientific breakthroughs that are the most critical for addressing the challenges that we face.Reverse Engineering is the traditional bread-and-butter of digital forensics research. Companies like Microsoft and Apple deliver computational artifacts (operating systems, applications and phones to the commercial market. These artifacts are bought and used by billions. Some have evil intent, and (if society is lucky, the computers end up in the hands of law enforcement. Unfortunately the original vendors rarely provide digital forensics tools that make their systems amenable to analysis by law enforcement. Hence the need for reverse engineering.(see PDF for full column

    In forensic casework analysis, identification of the biological matrix and the species of a forensic trace, preferably without loss of DNA, is of major importance. The biological matrices that can be encountered in a forensic context are blood (human or non-human), saliva, semen, vaginal fluid, and to a lesser extent nasal secretions, feces, and urine. All these matrices were applied on swabs and digested with trypsin in order to obtain peptides. These peptides were injected on a mass spectrometer (ESI Q-TOF) resulting in the detection of several biomarkers that were used to build a decision tree for matrix identification. Saliva and blood were characterized by the presence of alpha-amylase 1 and hemoglobin, respectively. In vaginal fluid, cornulin, cornifin, and/or involucrin were found as biomarkers while semenogelin, prostate-specific antigen, and/or acid phosphatase were characteristic proteins for semen. Uromodulin or AMBP protein imply the presence of urine, while plunc protein is present in nasal secretions. Feces could be determined by the presence of immunoglobulins without hemoglobin. The biomarkers for the most frequently encountered biological matrices (saliva, blood, vaginal fluid, and semen) were validated in blind experiments and on real forensic samples. Additionally, by means of this proteomic approach, species identification was possible. This approach has the advantage that the analysis is performed on the first "washing" step of the chelex DNA extraction, a solution which is normally discarded, and that one single test is sufficient to determine the identity and the species of the biological matrix, while the conventional methods require cascade testing. This technique can be considered as a useful additional tool for biological matrix identification in forensic science and holds the promise of further automation.

    Full Text Available Romanian animal, agricultural and biological sciences were seriously damaged in the period 1948-1964 by the introduction of the Stalinsko- lasenko approach in the field of Genetics and by an empiric-pragmatic approach of agricultural theory. In 1965, it started the reintroduction of the real genetic science and in 1969 a small group of scientists (22, 3 animal scientists, 3 agriculturalists registered in International Biometric Society aiming to change the scientific approach in experimental technique, genetic and animal breeding, ecological vision of animal production, education system. An international Congress of International Biometric Society was held in Romania. Some progress was achieved in all biological fields, but generally it was braked by the routine, by inertia. The number of Romanian agricultural members of Biometric Society decreased, the group disappeared after the year 1990, the biometricians were not present in research and education, but a correct approach is visible in Animal Breeding theory. It is noted that the biometric approach in biological sciences is originated from Darwin and Mendel theory, it was concretized by Galton and Pearson but the origin of Biometric Society (1946 is connected with S. Wright. Some basic scientific works of Quantitative Genetics and Evolution theory are noted.

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

    Wilkerson, Marianne Perry [Los Alamos National Laboratory

    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{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.

    The debate about the statistics of DNA profiling in forensic science casework has been carried out mainly from the perspective which is generally known as "match/binning." This approach has an initial appeal because of its apparent conceptual simplicity. However, the simplicity is illusory because it encourages misconceptions which obscure the essential forensic issues. This is exemplified in a recent report of the National Research Council, which places great emphasis on the need for conservative estimation of relative frequencies while missing the point that the power of RFLP technology cannot be realized if the matching stage is inefficient. Our approach to the problem is a one-stage rather than a two-stage process, by means of one function--the likelihood ratio--which determines the evidential strength. This paper describes experiments which have been carried out to assess the power of the method in forensic science and compares it with match/binning methodology. Tests for gauging the effects of between-probe dependence are included, with the results complementing those of Risch and Devlin. PMID:8095367

  20. Detection of Nanoscale Soil Organic Matter by Middle Infrared Spectrum for Forensic Science

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Soil is useful as a kind of trace evidence for forensic science. Thus it is very crucial to identify sources of soil. The nanoscale soil organic matter (NSOMs can be used to differentiate soil sources because their constituents and contents are relatively stable with time but variant by location. In this study, NSOMs from eighteen regions of Shandong Province in China were examined by middle infrared spectrum (4000–400 cm−1. The results showed that the constituents and contents of NSOMs in eighteen samples were dramatically different; a NSOM fingerprint for each sample was drawn based on these characteristics. This suggests that a national or global NSOM fingerprint database could be rapidly established by the one-step middle infrared spectrum analysis for different soil samples, which will be helpful to determine crime scenes by comparing the middle infrared spectrum of forensic soil with the NSOMs fingerprint database.

  1. Developing a one-semester course in forensic chemical science for university undergraduates

    Science.gov (United States)

    Salem, Roberta Sue

    The purpose of this study was to research, develop and validate a one-semester course for the general education of university undergraduates in forensic chemical education. The course outline was developed using the research and development (R&D) methodology recommended by Gall, Borg, and Gall, (2003) and Dick and Carey, (2001) through a three step developmental cycle. Information was gathered and analyzed through review of literature and proof of concept interviews, laying the foundation for the framework of the course outline. A preliminary course outline was developed after a needs assessment showed need for such a course. Professors expert in the area of forensic science participated in the first field test of the course. Their feedback was recorded, and the course was revised for a main field test. Potential users of the guide served as readers for the main field test and offered more feedback to improve the course.

    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.

  3. Identification of body fluid-specific DNA methylation markers for use in forensic science.

    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.

  6. 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

  7. [From popularization to participation: communicating science in the "knowledge society".

    Science.gov (United States)

    2017-01-01

    Vaccines are among the scientific topics that draw most interest in the public sphere. The discussion, however, can produce polarization, eventually becoming a controversy between "supporters of science" and "antiscience people". The aggressiveness of some anti-vaxxers, and their resistance to scientific evidence, can induce the belief that the confrontation is worthless, because many think that the top-down approach is the only one that can be used. The premise of this approach is that the gap of information is the main barrier between the scientific community and the society. However, from the '80s to date, studies have shown the fallacy of some assumptions of the so-called "deficit model", including the claim that the communication of science can be reduced only to dissemination and popularization of scientific facts. Studies and experiences, even in public health communications about vaccines, have highlighted the relevance of public engagement, social context, values systems, "lay knowledge" and the complexity of the relationship between science and society, fostering the emergence of new communication models. In the "knowledge society" we need effective communication to all, because people make use of scientific facts when they are involved in decisions on many public issues. Therefore, an evidence-based assessment of each communication approach and an evaluation of the effectiveness of methods in different contexts are required.

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

    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.

    In this feasibility study, we propose, for the first time, (1)H NMR spectroscopy coupled with mathematical strategies as a valid tool for body fluid (BF) trace identification in forensic science. In order to assess the ability of this approach to identify traces composed either by a single or by two different BFs, samples of blood, urine, saliva, and semen were collected from different donors, and binary mixtures were prepared. (1)H NMR analyses were carried out for all samples. Spectral data of the whole set were firstly submitted to unsupervised principal component analysis (PCA); it showed that samples of the same BF cluster well on the basis of their characterizing molecular components and that mixtures exhibit intermediate characteristics among BF typologies. Furthermore, samples were divided into a training set and a test set. An average NMR spectral profile for each typology of BF was obtained from the training set and validated as representative of each BF class. Finally, a fitting procedure, based on a system of linear equations with the four obtained average spectral profiles, was applied to the test set and the mixture samples; it showed that BFs can be unambiguously identified, even as components of a mixture. The successful use of this mathematical procedure has the advantage, in forensics, of overcoming bias due to the analyst's personal judgment. We therefore propose this combined approach as a valid, fast, and non-destructive tool for addressing the challenges in the identification of composite traces in forensics.

    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.

    To develop a cost-effective technique for single-nucleotide polymorphism (SNP) genotyping and improve the efficiency to analyze degraded DNA, we have established a novel multiplex system including 21-locus autosomal SNPs and amelogenin locus, which was based on allele-specific amplification (ASA) and universal reporter primers (URP). The target amplicons for each of the 21 SNPs arranged from 63 base pair (bp) to 192 bp. The system was tested in 539 samples from three ethnic groups (Han, Mongolian, and Zhuang population) in China, and the total power of discrimination (TPD) and cumulative probability of exclusion (CPE) were more than 0.99999999 and 0.98, respectively. The system was further validated with forensic samples and full profiles could be achieved from degraded DNA and 63 case-type samples. In summary, the multiplex system offers an effective technique for individual identification of forensic samples and is much more efficient in the analysis of degraded DNA compared with standard STR typing. © 2013 American Academy of Forensic Sciences.

    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. However, the reasonable development of position of these subjects in educational systems in individual countries across Europe is not so fast. The European Meteorological Society is trying to observe this process. Unfortunately the position of meteorology and climatology is not so well developed in framework of these subjects, there are some traces of our science in physics, but most of the small abundance of these topics are covered rather by geography. The low content is in contrary with the overall quite high interest in environmental issues in Europe. 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. EMS is performing this task through the Educational Committee which is trying to work under this EMS mission and objectives to help the process by means of its own activities and supporting some activities of EMS as a whole, e.g. organizing educational session of EMS Annual Meetings, cosponsoring other educational meeting etc. One of the elements of its own 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 place of Science education in the system. 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.

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

    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.

    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.

    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.

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.

  3. European Meteorological Society and education in atmospheric sciences, EWOC

    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 place of Science education in the system. 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. EMS is supporting the exchange of information in the area of education in atmospheric sciences, organizing the educational sessions during EMS annual meetings as well as participating in the series of International Conferences on School and Popular Meteorological and Oceanographic Education - EWOC (Education in Weather, Ocean and Climate).

    Full Text Available Seeking to understand the state of scientific consensus surrounding an area of forensics is often problematic. You cannot prove a claim about an unlimited set in the sense of testing every possibility. And yet there is a level of consensus surrounding the science of the day.This is a slightly altered portion of an expert report I wrote recently, released with permission, that I thought might serve as an example of how to go about seeking the truth and presenting the state of the science when truly definitive statements based on first principles are not available. Of course, I look forward to the readership proving me wrong with real-world examples, but somehow, I doubt if I will find any.(see PDF for full column

  6. 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...

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

    Bitzer, Sonja; Albertini, Nicola; Lock, Eric; Ribaux, Olivier; Delémont, Olivier

    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.

In forensic laboratories candidates who have chemistry/biochemistry undergraduate degree and took biology and forensic chemistry lectures are preferred. It is necessary to design graduate and undergraduate education to train a forensic chemist. Science education should be at the core of the undergraduate education. In addition to this strong laboratory education on both science and forensic science should be given. Th e graduate program of forensic science example should contain forensic science subjects, strong academic lectures on special subjects and research and laboratory components.

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

    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.

    Teaching and learning methods need a continuous upgrade in higher education. However it is also true that some of the modern methodologies do not reduce or prevent school failure. Perhaps the real limitation is the inability to identify the true reasons that may explain it or ignore/undervalue the problem. In our opinion, one of the current constraints of the teaching/learning process is the excess of and inadequate bibliography recommended by the teacher, which results in continuous student difficulties and waste of time in searching and selecting useful information. The need to change the paradigm of the teaching/learning process comes also from employers. They claim forensic experts armed with useful knowledge to face professional life. It is therefore mandatory to identify the new needs and opportunities regarding pedagogical methodologies. This article reflects on the recent importance of peer review in teaching/learning forensic sciences based on the last 10 years of pedagogical experience inseparably from the scientific activity.

    2015-09-01

    This study presents an innovative methodology for forensic science image analysis for event reconstruction. The methodology is based on experiences from real cases. It provides real added value to technical guidelines such as standard operating procedures (SOPs) and enriches the community of practices at stake in this field. This bottom-up solution outlines the many facets of analysis and the complexity of the decision-making process. Additionally, the methodology provides a backbone for articulating more detailed and technical procedures and SOPs. It emerged from a grounded theory approach; data from individual and collective interviews with eight Swiss and nine European forensic image analysis experts were collected and interpreted in a continuous, circular and reflexive manner. Throughout the process of conducting interviews and panel discussions, similarities and discrepancies were discussed in detail to provide a comprehensive picture of practices and points of view and to ultimately formalise shared know-how. Our contribution sheds light on the complexity of the choices, actions and interactions along the path of data collection and analysis, enhancing both the researchers' and participants' reflexivity.

    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.

    Full Text Available The concept of using dental evidence in forensic investigation has kindled so much interest in the recent past that forensic odontology is even suggested as the single positive identification method to solve certain forensic cases. In this process, the shortcomings in forensic odontology though few are overlooked. These discrepancies associated with various methods are to be weighed cautiously to make forensic odontology a more accurate, reliable, and reproducible investigatory science. In this paper, we present our understanding of the limitations in various methods employed in forensic odontology.

    The new NSF Math Science Partnership (MSP) program seeks to reform and strengthen elementary and secondary education by uniting the efforts of local school districts with: college level science, mathematics, engineering and education faculties; state government agencies; and other stakeholders, such as non-profit organizations and scientific societies. With recent passage of a Council position statement in support of teaching the Earth and space sciences in grades K-12 following the national science standards, AGU has affirmed its interest in contributing to efforts to improve pre-college science education. The challenge is how best to utilize AGU's resources within the context of the MSP program guidelines. One of AGU's most important roles will be to facilitate dissemination of "best practices" from successful state partnerships, thereby providing model programs for others AGU members who wish to establish MSPs in their own communities. But, AGU can also take a leadership role in bringing the groups together and helping to expand state-based programs to a broader national, and even international, audience. One example of such a partnership is a new program being initiated by AGU that focuses on the upcoming 400th anniversary of the settling of the Jamestown colony. AGU is currently working to establish a partnership with Virginia state geologists and climatologists, members of the Virginia Department of Education, researchers at William and Mary College and the Virginia Institute of Marine Science, and the GLOBE program, in order to develop education materials and programs that examine geological and environmental changes that have occurred in the Chesapeake Bay region during the last 400 years. A variety of products are under consideration that include curricular materials and hands-on research activities for K-12 students, as well as monographs that can be used in both formal and informal education settings.

    The study comprises the analysis of expert's hemogenetic reports carried out in the Department of Forensic Medicine, University of Medical Sciences in Poznan, in the years 1980-2004 and associated with paternity determination or exclusion. In the analyzed period, the authors established 1064 cases of paternity exclusion in serological tests, 97 paternity exclusions in the HLA examinations, and 129 cases of paternity exclusions processed in DNA testing. On the base of gene frequencies, the theoretical chance of paternity exclusion was determined for every test. The significant usefulness of DNA testing in legal processes did not cause an increase in the percentage of paternity exclusions. Moreover, the authors observed a significant decrease in the number of paternity exclusions in comparison with results of serological tests (from 24.25% to 19.43%). With the drop in the number of births, the number of expert's reports significantly decreased.

  19. Geoethics and Forensic Geology

    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

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

    2011-01-01

    Full Text Available Abstract 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.

  2. Impact factors of forensic science and toxicology journals: what do the numbers really mean?

    2003-04-23

    This article presents review and opinion about the use and abuse of journal impact factors for judging the importance and prestige of scientific journals in the field of forensic science and toxicology. The application of impact factors for evaluating the published work of individual scientists is also discussed. The impact factor of a particular journal is calculated by dividing the number of current year citations to a journal's articles that were published in the previous 2 years by the total number of citable items (articles and reviews) published in the same 2-year period. Journal impact factors differ from discipline to discipline and range from 0 for a journal whose articles are not cited in the previous 2 years to 46 for a journal where the average recent article is cited 46 times per year. The impact factor reflects the citation rate of the average article in a journal and not a specific article. Many parameters influence the citation rate of a particular journal's articles and, therefore, its impact factor. These include the visibility and size of the circulation of the journal including availability of electronic formats and options for on-line search and retrieval. Other things to consider are editorial standards especially rapid and effective peer-reviewing and a short time lag between acceptance and appearance in print. The number of self-citations and citation density (the ratio of references to articles) and also the inclusion of many review articles containing hundreds of references to recently published articles will boost the impact factor. Judging the importance of a scientist's work based on the average or median impact factor of the journals used to publish articles is not recommended. Instead an article-by-article citation count should be done, but this involves much more time and effort. Moreover, some weighting factor is necessary to allow for the number of co-authors on each article and the relative positioning of the individual names

    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.

    Brownfield Action (BA - http://www.brownfieldaction.org) is a web-based, interactive, three-dimensional digital space and learning simulation in which students form geotechnical consulting companies and work collaboratively to explore and solve problems in environmental forensics. BA is being used in the United States at 10 colleges and universities in earth, environmental, or engineering sciences undergraduate and graduate courses. As a semester-long activity or done in modular form for specific topics, BA encourages active learning that requires attention to detail, intuition, and positive interaction between peers that results in Phase 1 and Phase 2 Environmental Site Assessments. Besides use in higher education courses, BA also can be adapted for instruction to local, state, and federal governmental employees, and employees in industry where brownfields need to be investigated or require remediation.

    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.

    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.

    The Science Technology Society (STS) approach is a major science education reform through which a scientifically literate citizen could be produced. The teaching of science through STS approach is centered on science and technology related issues and problems. The purpose of this study was to analyze five earth science textbooks published in the 1990's for their inclusion of twelve sciences and technology related issues and problems and for their inclusion of activities focused on STS. The selected earth science textbooks were; Scott Foresman, Heath, Holt, Merrill and Prentice-Hall. The targeted twelve issues and problems were identified by Bybee (1987), as the most important global science and technology related issues and problems. The numbers of full text pages devoted to each topic were determined by classifying each segment to one of the targeted topics. In addition, the numbers of STS activities were also determined by using criteria developed for this study. ANOVA statistical analyses and t-tests showed that the analyzed earth science textbooks treated the studied STS issues and problems and treated the STS activities differently. It was found that six of the studied issues and problems were constantly receiving more attention in all the analyzed earth science textbooks than the rest of the topics. These topics were; Air Quality and Atmosphere, Energy Shortages, Water Resources, Land Use, Hazardous Substances, and Mineral Resources. The overall results revealed that only an average of 8.82% of the text pages in all the analyzed earth science textbooks were devoted to STS topics and 5.49% of the activities in all the analyzed earth science textbooks were focused on STS topics. However, none of the activities focused on STS topics were presented in STS approach as defined by NSTA. The percentage of STS topics inclusion and the percentage of activities focused on STS topics were considered to be very low. Accordingly, the objectives and goals of STS approach

    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

    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.

    Environmental issues typically occur at the intersection of traditional disciplines such as biology, geology, economics, public policy, and sociology, but many undergraduate students possess neither the tools nor the required interdisciplinary skills to effectively work together to address these complex issues. Our REU program--Interdisciplinary Watershed Studies at the College of William and Mary--with its common watershed theme, improves our students' independence as scientists, increases environmental science literacy across disciplines, and contributes to the educational development of undergraduates as environmental spokespersons. The cohort of students work with W&M faculty mentors on aquatic and associated upland habitats under increasing pressures from urbanization, posing questions integrated across disciplines to address relevant management issues identified by local government agencies and NGOs. Investigations of current hydrogeologic and ecological status in watersheds are completed by analyzing riparian corridor impacts associated with channel incision, stormwater management effectiveness, spatial variation in water quality, lake-wide budgets for water, sediment and nutrients, and population/community structure in aquatic and terrestrial portions of the watershed. Because the status of any watershed system is the result of historical changes in land use, sociologic and economic surveys of residents' perception of development, environmental protection and water and property rights are used to determine the current direction and strength of population and market forcing functions. Students work on each other's projects and develop an understanding of research approaches among fields. In addition to presenting their work at scientific conferences, many students give presentations at local meetings and agency workshops to enhance science-society links. Watershed analysis provides a comprehensive approach to environmental instruction that strengthens the

    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...

    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.

    Lecture will be in English– Translation available in French Without any doubt, CERN can be described as being among the most ambitious scientific enterprises ever undertaken. 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 ...

  1. New perspectives in the use of ink evidence in forensic science: Part III: Operational applications and evaluation.

    Neumann, Cedric; Margot, Pierre

    2009-11-20

    The research reported in this series of article aimed at (1) automating the search of questioned ink specimens in ink reference collections and (2) at evaluating the strength of ink evidence in a transparent and balanced manner. These aims require that ink samples are analysed in an accurate and reproducible way and that they are compared in an objective and automated way. This latter requirement is due to the large number of comparisons that are necessary in both scenarios. A research programme was designed to (a) develop a standard methodology for analysing ink samples in a reproducible way, (b) comparing automatically and objectively ink samples and (c) evaluate the proposed methodology in forensic contexts. This report focuses on the last of the three stages of the research programme. The calibration and acquisition process and the mathematical comparison algorithms were described in previous papers [C. Neumann, P. Margot, New perspectives in the use of ink evidence in forensic science-Part I: Development of a quality assurance process for forensic ink analysis by HPTLC, Forensic Sci. Int. 185 (2009) 29-37; C. Neumann, P. Margot, New perspectives in the use of ink evidence in forensic science-Part II: Development and testing of mathematical algorithms for the automatic comparison of ink samples analysed by HPTLC, Forensic Sci. Int. 185 (2009) 38-50]. In this paper, the benefits and challenges of the proposed concepts are tested in two forensic contexts: (1) ink identification and (2) ink evidential value assessment. The results show that different algorithms are better suited for different tasks. This research shows that it is possible to build digital ink libraries using the most commonly used ink analytical technique, i.e. high-performance thin layer chromatography, despite its reputation of lacking reproducibility. More importantly, it is possible to assign evidential value to ink evidence in a transparent way using a probabilistic model. It is therefore

    Standards published by the Association of Forensic Science Providers (2009, Standards for the formulation of evaluative forensic science expert opinion, Science & Justice, Vol. 49, pp. 161-164) encourage forensic scientists to express their conclusions in the form of a likelihood ratio (LR), in which the value of the evidence is conveyed verbally or numerically. In this article, we report two experiments (using undergraduates and Mechanical Turk recruits) designed to investigate how much decision makers change their beliefs when presented with evidence in the form of verbal or numeric LRs. In Experiment 1 (N = 494), participants read a summary of a larceny trial containing inculpatory expert testimony in which evidence strength (low, moderate, high) and presentation method (verbal, numerical) varied. In Experiment 2 (N = 411), participants read the same larceny trial, this time including either exculpatory or inculpatory expert evidence that varied in strength (low, high) and presentation method (verbal, numerical). Both studies found a reasonable degree of correspondence in observed belief change resulting from verbal and numeric formats. However, belief change was considerably smaller than Bayesian calculations would predict. In addition, participants presented with evidence weakly supporting guilt tended to "invert" the evidence, thereby counterintuitively reducing their belief in the guilt of the accused. This "weak evidence effect" was most apparent in the verbal presentation conditions of both experiments, but only when the evidence was inculpatory. These findings raise questions about the interpretability of LRs by jurors and appear to support an expectancy-based account of the weak evidence effect.

    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.

  10. Bridging the gap: from biometrics to forensics.

    Science.gov (United States)

    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.

  11. The Role of Historians of Science in Contemporary Society

    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.

    Soil vestiges might provide information about a crime scene. The Rietveld method with X-ray diffraction data (RM-XRD) is a nondestructive technique that makes it possible to characterize minerals present in the soils. Soil clays from the metropolitan region of Curitiba (Brazil) were submitted to DCB treatment and analyzed using XRD with CuKα radiation in the step-scan mode (0.02° 2θ/5 s). The GSAS+EXPGUI software was used for RM refinement. The RM-XRD results, together with the principal component analysis (PCA) (52.6% total variance), showed the kaolinite predominance in most analyzed samples and the highest quartz contents in "site 1." Higher anatase, and gibbsite and muscovite contents influenced discrimination, mainly in "site 3" and "site 1," respectively. These results were enough to discriminate clays of four sites and two horizons using a reduced amount of sample showing that the technique can be applied to the investigation into soil vestiges. © 2017 American Academy of Forensic Sciences.

    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

    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.

    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.

    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...

    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

    Background 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 compute...

  8. Women's rights in Pakistan: a forensic perspective.

    Science.gov (United States)

    Hadi, Sibte

    2003-04-01

    Pakistan is a large and an important West Asian country which came into being in the name of Islam and therefore Islamic tenets remain the core of its constitution. The laws of the state have to conform to Islamic law so that they can have a positive impact on the society. Unfortunately, in Pakistan today not all men enjoy the rights and facilities to which they are entitled and women are doubly disadvantaged by poverty and gender. With their own political agendas, various governments have promulgated laws which affect the society in various ways. The laws which directly influence women's rights merit mention, as women comprise more than 50% of the population of Pakistan and are still kept on the sidelines by the male dominant society. The Muslim Family Law Ordinance, 1961, and the Hudood Ordinance, 1979 were both promulgated by military dictators with different visions. The former codified the rights of women bestowed by Islamic law; the latter repealed laws for sexual offences according to the injunctions of Islam and had a negative impact. Both laws need the assistance of forensic medicine as age estimation and medical examinations are necessary if they are to be followed in the right perspective. However, a legal need for an examination by an expert in forensic medicine is sadly lacking in both laws. This has happened due to lack of training of forensic physicians and therefore a lack of research in important areas of forensic medicine in the country. This paper examines these laws and the interaction they have with forensic medicine and proposes that the laws need revision in accordance with modern science, incorporating forensic sciences as well as the injunctions of Islam.

  9. Microbial forensics: the next forensic challenge.

    Budowle, Bruce; Murch, Randall; Chakraborty, Ranajit

    2005-11-01

    Pathogens and toxins can be converted to bioweapons and used to commit bioterrorism and biocrime. Because of the potential and relative ease of an attack using a bioweapon, forensic science needs to be prepared to assist in the investigation to bring perpetrators to justice and to deter future attacks. A new subfield of forensics--microbial forensics--has been created, which is focused on characterization of evidence from a bioterrorism act, biocrime, hoax, or an inadvertent release. Forensic microbiological investigations are essentially the same as any other forensic investigation regarding processing. They involve crime scene(s) investigation, chain of custody practices, evidence collection, handling and preservation, evidence shipping, analysis of evidence, interpretation of results, and court presentation. In addition to collecting and analyzing traditional forensic evidence, the forensic investigation will attempt to determine the etiology and identity of the causal agent, often in a similar fashion as in an epidemiologic investigation. However, for attribution, higher-resolution characterization is needed. The tools for attribution include genetic- and nongenetic-based assays and informatics to attempt to determine the unique source of a sample or at least eliminate some sources. In addition, chemical and physical assays may help determine the process used to prepare, store, or disseminate the bioweapon. An effective microbial forensics program will require development and/or validation of all aspects of the forensic investigative process, from sample collection to interpretation of results. Quality assurance (QA) and QC practices, comparable to those used by the forensic DNA science community, are being implemented. Lastly, partnerships with other laboratories will be requisite, because many of the necessary capabilities for analysis will not reside in the traditional forensic laboratory.

  11. Decomposition and dipteran succession in pig carrion in central Argentina: ecological aspects and their importance in forensic science.

    Horenstein, M Battán; Linhares, A Xavier; De Ferradas, B Rosso; García, D

    2010-03-01

    Data on the insect species associated with corpse decomposition are particularly important for estimation of the post-mortem interval (PMI) in forensic science because the PMI is based on the lifecycle and behaviour of necrophagous insects, among other measures. To determine the dipteran succession on pig carrion, four experiments, one in each season, were carried out during 2004 in a rural area of Córdoba, central Argentina. Two pigs (Sus scrofa L.) were used in each of the four experiments. At each time-point one pig was placed in the shade and the other under direct sunlight. Insects were collected daily during the first 4 weeks and thereafter every 2 or 3 days. Five stages of decomposition were observed and a total of 24 710 adult specimens were collected, belonging to the following eight families of Diptera: Calliphoridae; Muscidae; Sarcophagidae; Phoridae; Piophilidae; Fanniidae; Sphaeroceridae, and Anthomyiidae. All Calliphoridae collected in this study were considered to be of potential forensic importance because of their necrophagous behaviour and because their immature stages use carrion as a food source. Other species, such as Musca domestica L. and Ophyra aenescens (Wiedemann), were also considered to represent potential forensic indicators.

  12. [Forensic entomology].

    2010-01-01

    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.

    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.

  14. Historical Highlights From 75 Years of the Soil Science Society of America

    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

    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 ».

    RNA has received more attention in the field of forensic medicine and the development of the new biological markers based on RNA shows great significance in the analysis of complex cases. circular RNA (circRNA) is a kind of non-coding RNA which is widely reported recently. Although the regulatory mechanisms of generation and expression are not fully clear, the existing research indicates that circRNA has important biological functions. CircRNA has a cell-type-specific expression with great stability and a high expression level, which makes it meaningful in forensic applications potentially. In this paper, the research progress, the generation and regulation of circRNA as well as its biological characteristics and functions are summarized, which will provide references for related studies and forensic applications.

  5. 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

  6. 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.

  7. EU-PolarNet: Connecting Science with Society

    Science.gov (United States)

    Biebow, N.

    2015-12-01

    The rapid changes occurring in the Polar Regions are significantly influencing global climate with consequences for global society. European and international polar research has contributed critical knowledge to identifying the processes behind these rapid changes but datasets from the Polar Regions are still insufficient to fully understand and more effectively predict the effects of change on our climate and society. This situation can only be improved by a more holistic integrated scientific approach, a higher degree of coordination of polar research and closer cooperation with all relevant actors on an international level. The objectives of EU-PolarNet are to establish an on-going dialogue between policy-makers, business and industry leaders, local communities and scientists to increase mutual understanding and identify new ways of working that will deliver economic and societal benefits. The results of this dialogue will be brought together in an Integrated European Research Programme that will be co-designed with all relevant stakeholders and coordinated with the activities of polar research nations beyond Europe. This programme will be accompanied by a feasible implementation plan to provide the Polar community with the capability to define the nature of environmental risks so that governments can design policy measures to mitigate them and businesses and other stakeholders benefit from the opportunities that are opening up in the Polar Regions.

  8. Twelve messages from enteric infections for science and society.

    Science.gov (United States)

    Guerrant, R L

    1994-07-01

    Diarrheal diseases hold profound messages as well as opportunities that range from public health to basic science. From the spread of cholera around the world, we are reminded of the global impact of tropical diseases, that disease may provide a litmus test for poverty to drive a sanitary revolution, that disease spread may be worsened by political denial, and that many ecologic and epidemiologic secrets such as interepidemic microbial niches remain poorly understood. Diarrheal diseases other than cholera teach us that heavy disease burdens do not control population growth but are associated with population overgrowth (i.e., improved health is key to controlling the population explosion), the societal impact of diarrhea morbidity may exceed even that of its mortality, that new agents continue to emerge, and that nosocomial diarrhea is an underrecognized threat in our hospitals. Finally, from the laboratory of the developing world also come messages for basic science. Microbial toxins continue to elucidate a new understanding of cell signaling, and mechanisms once thought to be clear (such as that of cholera toxin) now appear much more complex. Traditional remedies hold new pharmacologic secrets, e.g., such as gingko extracts that inhibit platelet-activating factor. Finally, from basic physiology can come widely applicable practical solutions such as oral rehydration therapy and simplified diagnostics for inflammatory diarrhea. Health problems such as diarrheal diseases that plague the disadvantaged are linked to population overgrowth and provide some of the greatest challenges to modern science and the industrialized world.

    2007-03-01

    Full Text Available We inhabit an age in which economic progress in the European Union is equalized to more European research and better communication of that European research to the public. In highly developed Western democracies this implies an important role for the public as well as the mass media, both actors in a transforming public sphere. Beyond a call for more communication and more scientific literacy, the discourse has shifted to a call for more engagement and more participation on behalf of the citizen. There is a widespread sentiment however that the discipline of science communication is at a crossroads. In this paper it is argued that in a context of life politics and an increasing displacement of politics, one has to account for the trajectories of issue formation and the detours of public-ization to understand the dynamics of techno-scientific issues.

    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.

  19. Science, religion, and society: the problem of evolution in America.

    Science.gov (United States)

    Coyne, Jerry A

    2012-08-01

    American resistance to accepting evolution is uniquely high among First World countries. This is due largely to the extreme religiosity of the United States, which is much higher than that of comparably advanced nations, and to the resistance of many religious people to the facts and supposed implications of evolution. The prevalence of religious belief in the United States suggests that outreach by scientists alone will not have a huge effect in increasing the acceptance of evolution, nor will the strategy of trying to convince the faithful that evolution is compatible with their religion. Because creationism is a symptom of religion, another strategy to promote evolution involves loosening the grip of faith on America. This is easier said than done, for recent sociological surveys show that religion is highly correlated with the dysfunctionality of a society, and various measures of societal health show that the United States is one of the most socially dysfunctional First World countries. Widespread acceptance of evolution in America, then, may have to await profound social change.

  20. 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

    Water is fundamental to life on Earth. Knowing where and how much rain and snow falls globally is vital to understanding how weather and climate impact both our environment and Earth's water and energy cycles, including effects on agriculture, fresh water availability, and responses to natural disasters. The Global Precipitation Measurement (GPM) Mission, launched February 27, 2014, is an international satellite mission to unify and advance precipitation measurements from a constellation of research and operational sensors to provide "next-generation" precipitation products. The joint NASA-JAXA GPM Core Observatory serves as the cornerstone and anchor to unite the constellation radiometers. The GPM Core Observatory carries a Ku/Ka-band Dual-frequency Precipitation Radar (DPR) and a multi-channel (10-183 GHz) GPM Microwave Radiometer (GMI). Furthermore, since light rain and falling snow account for a significant fraction of precipitation occurrence in middle and high latitudes, the GPM instruments extend the capabilities of the TRMM sensors to detect falling snow, measure light rain, and provide, for the first time, quantitative estimates of microphysical properties of precipitation particles. As a science mission with integrated application goals, GPM is designed to (1) advance precipitation measurement capability from space through combined use of active and passive microwave sensors, (2) advance the knowledge of the global water/energy cycle and freshwater availability through better description of the space-time variability of global precipitation, and (3) improve weather, climate, and hydrological prediction capabilities through more accurate and frequent measurements of instantaneous precipitation rates and time-integrated rainfall accumulation. Since launch, the instruments have been collecting outstanding precipitation data.

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

    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

  3. Forensic geomorphology

    Ruffell, Alastair; McKinley, Jennifer

    2014-02-01

    Geomorphology plays a critical role in two areas of geoforensics: searching the land for surface or buried objects and sampling scenes of crime and control locations as evidence. Associated geoscience disciplines have substantial bodies of work dedicated to their relevance in forensic investigations, yet geomorphology (specifically landforms, their mapping and evolution, soils and relationship to geology and biogeography) have not had similar public exposure. This is strange considering how fundamental to legal enquiries the location of a crime and its evolution are, as this article will demonstrate. This work aims to redress the balance by showing how geomorphology featured in one of the earliest works on forensic science methods, and has continued to play a role in the sociology, archaeology, criminalistics and geoforensics of crime. Traditional landscape interpretation from aerial photography is used to demonstrate how a geomorphological approach saved police time in the search for a clandestine grave. The application geomorphology has in military/humanitarian geography and environmental/engineering forensics is briefly discussed as these are also regularly reviewed in courts of law.

  4. 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.

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

    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

    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

    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.

    2016-05-01

    Full Text Available Teaching and learning methods need a continuous upgrade in higher education. However it is also true that some of the modern methodologies do not reduce or prevent school failure. Perhaps the real limitation is the inability to identify the true reasons that may explain it or ignore/undervalue the problem. In our opinion, one of the current constraints of the teaching/learning process is the excess of and inadequate bibliography recommended by the teacher, which results in continuous student difficulties and waste of time in searching and selecting useful information. The need to change the paradigm of the teaching/learning process comes also from employers. They claim forensic experts armed with useful knowledge to face professional life. It is therefore mandatory to identify the new needs and opportunities regarding pedagogical methodologies. This article reflects on the recent importance of peer review in teaching/learning forensic sciences based on the last 10 years of pedagogical experience inseparably from the scientific activity.

    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 English Speaking Working Group (ESWG) of the International Society for Forensic Genetics (ISFG) offers an annual Paternity Testing Workshop open to all members of the group. Blood samples, a questionnaire and a paper challenge are sent to the participants. Here, we present the results of the 2002-2008 Paternity Testing Workshops with the objective to evaluate the uniformity of DNA-profiling and conclusions of the participating laboratories as well as to clarify tendencies in typing strategies and biostatistical evaluations of the laboratories. The numbers of participating laboratories increased from 46 in 2002 to 68 in 2008. The results showed an increasing degree of concordance concerning methods and DNA systems used and a high degree of uniformity in typing results with discrepancies in 0.1 and 0.3 % of all submitted PCR-based results. The paper challenges showed uniformity in the calculation of the weight of evidence for simple cases with straight-forward genetic constellations. However, a high degree of variation existed in complex scenarios with rare genetic constellations such as genetic inconsistencies/possible silent alleles, rare alleles and haplotypes.

    2012-10-01

    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).

    Jain, Anil K.; Ross, Arun

    2015-01-01

    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. PMID:26101280

    Kelty, Sally F; Julian, Roberta; Ross, Alastair

    2013-07-10

    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.

  8. Application possibilities of several modern methods of microscopy and microanalysis in forensic science field

    Science.gov (United States)

    Kotrly, Marek; Turkova, Ivana

    2011-06-01

    The methods of optical and electron microscopy and microanalysis are the linchpin of forensic inorganic analysis. However, their capacity is limited as for the exact identification of pigments and colour layers, and therefore it is essential that they be complemented by other methods of phase microanalysis - powder X-ray microdiffraction (micro pXRD) and FTIR in transmission mode. The classic way of sample division for different methods is not suitable with regard to the inhomogeneity of the sequence of strata. That is why a method was tested that would allow performance of optical microscopy, SEM/EDS(WDS), micro pXRD and FTIR in a nondestructive manner, from an identical spot of a single fragment. The solution can be polished sections - embedded samples and microtome sections. Conductive zerobackground single-crystal silicon plates were developed and tested for sample fixation in SEM, micro pXRD and transmission FTIR. Methods using a focused ion beam - FIB have recently gained importance in the field of electron microscopy. In the forensic sphere they can be employed in examinations of metal materials, technical analyses of documents, post-blast and gunshot residues.

    Frontal sinus pattern matching is a useful means of forensic identification. By the use of radiographs forensic scientists have recognized that there are diverse anatomical variations in the structure of the frontal sinus. Radiographs are a diagnostic tool, widely used in dental practices, hospitals and other health disciplines. Most health institutions possess the facility to store radiographs over long periods of time. Frontal sinus pattern matching technique can be applied in cases where ante mortem frontal sinus radiographs are available and dental matching cannot be carried out. Frontal sinus pattern matching technique may also be used to corroborate identifications based on other techniques such as fingerprints, teeth, or circumstantial evidence. The present study was carried out to assess the effectiveness of using the radiographic image of the frontal sinus for personal identification in studied population group. The results concluded that the appearance of the radiographic image of the frontal sinus is unique for each individual. On this evidence it is proposed that frontal sinus pattern matching can be used for personal identification when other methods have failed.

    Kosaki, Takashi

    2013-04-01

    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

    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.

  13. Overview Of Forensic Toxicology, Yesterday, Today And In The Future.

    2017-06-22

    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 bench-top 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.

    Full Text Available This article is a study of the application of the Questionnaire of Opinions on Science, Technology and Society (COCTS with a new methodology based on a multiple-response model, to achieve a more valid and meaningful assessment of attitudes regarding issues of science, technology & society (STS, in a sample of high school students. It presents the application of this methodology and its ability to evaluate more precisely, both qualitatively and quantitatively, the STS attitudes of students whose overall level is mediocre, since they are outstanding for their lesser adaptation, and their beliefs about science epistemology. It also shows the lack of equivalence between isolated statements used to assess attitudes and their methodological implications for research on attitudes. Finally, it suggests some implications of the results for teaching STS themes in the school.

    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.

    2015-07-01

    Soil samples have potential to be useful in forensic investigations, but their utility may be limited due to the inherent variability of soil properties, the wide array of analytical methods, and complexity of data analysis. This study examined the differentiation of similar soils based on both gross (texture, color, mineralogy) and explicit soil properties (elemental composition, cation exchange, Fe-oxyhydroxides). Soils were collected from Fallbrook and adjacent map units from Riverside and San Diego Counties in California. Samples were characterized using multiple techniques, including chemical extracts, X-ray diffraction (XRD), and Fourier transform infrared spectroscopy. Results were analyzed using multiple analytical approaches to compare counties and land uses. Some analyses (XRD, extractions) were better at distinguishing among samples than others (color, texture). Ratios of rare earth elements were particularly useful for distinguishing samples between counties. This potential to "fingerprint" soils illustrates the usefulness of a comprehensive soil database for criminal investigators.

    Forensic odontology explores the field of human identification through dental tissues in cases where there is destruction of body tissues in criminal investigations and mass disasters. Forensic odontology involves dentists participating in legal and criminal issues. Parameters such as age and gender identification are important in identifying the person or persons. Over the last two decades, the molecular aspect of forensic sciences has increased, and these molecular techniques now provide a novel approach to forensic odontology. Molecular advancements in science like DNA analysis has extended the range of forensic dentistry as teeth possess the character of resistance toward physical or chemical aggressions. Teeth provide the abundant space for DNA, and hence teeth represent an excellent source of genomic DNA. The present paper focusses on molecular advancements in the field of forensic odontology.

  19. Quantitative Analysis of Complex Multiple-Choice Items in Science Technology and Society: Item Scaling

    Directory of Open Access Journals (Sweden)

    Ángel Vázquez Alonso

    2005-05-01

    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.

    2009-01-01

    The intersection of science and our society has led to legal and ethical issues in which we all play a part. To support development of scientific literacy, college science courses need to engage students in difficult dialogues around ethical issues. We describe a new course, Stem Cells and Society, in which students explore the basic biology of stem cell research and the controversy surrounding it. As part of the course, we highlight the nature of science, looking at the methods and norms within the scientific community. To gain a perspective on the current stem cell controversy, we examine the public debates in the 1970s surrounding in vitro fertilization, the stem cell initiative in Missouri, and the personal and religious viewpoints that have emerged relative to the stem cell debate. In the Stem Cells and Society course, students are challenged to develop and clarify their own personal positions concerning embryonic stem cell research. These positions are grounded in science, religion or personal philosophy, and law.

    2017-04-01

    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.

  4. Marginalization of Socioscientific Material in Science-Technology-Society Science Curricula: Some Implications for Gender Inclusivity and Curriculum Reform

    Science.gov (United States)

    Hughes, Gwyneth

    2000-05-01

    Science education reformers have argued that presenting science in the abstract is neither motivating nor inclusive of the majority of students. Science-technology-society (STS) curricula that give science an accessible social context have developed in response, but controversy surrounds the extent to which students should be introduced to socioscientific debate. Using material from a case study of Salters' Advanced Chemistry in the United Kingdom, this article demonstrates how socioscientific material is marginalized through the structures and language of syllabus texts and through classroom practices. This means students are unlikely to engage with socioscientific aspects in their course. Socioscientific content is gendered through association with social concerns and epistemological uncertainty, and because gender is asymmetric, socioscience is devalued with respect to the masculinity of abstract science. Teachers fear that extensive coverage of socioscience devalues the curriculum, alienates traditional science students and jeopardizes their own status as gatekeepers of scientific knowledge. Thus, although STS curricula such as Salters' offer potential for making science more accessible, the article concludes that greater awareness of, and challenges to, gender binaries could result in more effective STS curriculum reform.

  5. Forensic toxicology.

    Drummer, Olaf H

    2010-01-01

    Forensic toxicology has developed as a forensic science in recent years and is now widely used to assist in death investigations, in civil and criminal matters involving drug use, in drugs of abuse testing in correctional settings and custodial medicine, in road and workplace safety, in matters involving environmental pollution, as well as in sports doping. Drugs most commonly targeted include amphetamines, benzodiazepines, cannabis, cocaine and the opiates, but can be any other illicit substance or almost any over-the-counter or prescribed drug, as well as poisons available to the community. The discipline requires high level skills in analytical techniques with a solid knowledge of pharmacology and pharmacokinetics. Modern techniques rely heavily on immunoassay screening analyses and mass spectrometry (MS) for confirmatory analyses using either high-performance liquid chromatography or gas chromatography as the separation technique. Tandem MS has become more and more popular compared to single-stage MS. It is essential that analytical systems are fully validated and fit for the purpose and the assay batches are monitored with quality controls. External proficiency programs monitor both the assay and the personnel performing the work. For a laboratory to perform optimally, it is vital that the circumstances and context of the case are known and the laboratory understands the limitations of the analytical systems used, including drug stability. Drugs and poisons can change concentration postmortem due to poor or unequal quality of blood and other specimens, anaerobic metabolism and redistribution. The latter provides the largest handicap in the interpretation of postmortem results.

    Over the past year, we began a new research project to uncover general education astronomy students’ worldviews, their ideas about the role science plays in society, and the effects instruction has on these beliefs. Over the course of the spring 2012 semester, we collected students’ written responses to several open-ended, provocative questions that investigate students’ ideas about the impact science has had on areas such as the economy, their daily lives, and their fundamental beliefs about the nature of reality. This talk will present our preliminary findings from this project. This material is based upon work supported by the National Science Foundation under Grant No. 0833364 and Grant No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS).

    2015-01-01

    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.

    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.

    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.

    Evaluative forensic science opinions should be presented in a form that can be accommodated within that process of criminal proof demanded by judges and applied by juries. This is a non-mathematical inductive process that seeks‘the inference to best explanation’ to a standard of proof beyond reasonable doubt. The question posed is not the mathematical probability of the prosecution hypothesis but whether, having regard to all the evidence properly before the court, the prosecution hypothesis is the only explicable hypothesis. To ensure that a jury remains focused on applying this legal standard it is argued that evaluative forensic science evidence tendered by the prosecution should be expressed not as a likelihood ratio that emphasizes the greater likelihood of ifnding evidence if the prosecution’s contentions are true, but in a form that emphasises the ranges of explanations for the evidence consistent with the defence case and that must be excluded as a reasonable possibility having regard to all the evidence before the accused can be convicted.%法庭科学评价意见在法庭上陈述的方式应当与法官所要求、陪审团实际应用的刑事证明程序相兼容。这并非一个数值性的归纳过程,而是在探求排除合理怀疑证明标准下的“最佳解释推理”。面临的问题并不是控方主张的数学概率问题,而是在全面考量了法庭上出示的所有证据后,控方主张是否为唯一可解释假说的问题。为确保陪审团仍然能专注地运用这一法律证明标准,笔者主张,控方提出的评价性法庭科学证据不应当以似然比的形式在强调若控方主张为真便更有可能认定证据,而应聚焦于本方证据对辩方有利的解释范围并在被告被定罪之前排除掉所有这些解释的合理可能性。

  15. The soil education technical commission of the Brazilian Soil Science Society: achievements and challenges

    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

    The traces produced when a firearm is discharged can provide important information in cases when questions regarding a possible association of the firearm with a person of interest (POI), time since discharge or shooting distance are raised. With advances in technology, the forensic challenges presented by these traces, known as gunshot residues (GSR), are moving from the analytical domain to the interpretation of the analytical results. Different interpretation frameworks are currently competing. Formal classification of particles, using standards such as that produced by ASTM, focusses only on evaluation of evidence at the sub-source level. Another approach, based on the application of Bayesian reasoning - namely the case-by-case approach - has been proposed that allows evaluation of evidence in regards to activity-related questions. This alternative approach allows an evaluation of the evidence that is more closely aligned to judicial and investigative aims. This paper critically presents the state of the art in regards to GSR interpretation in a holistic manner. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  18. 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.

    According to the old testament Adam was convinced by eve to put a "Bite Mark" on the apple. Interest in Forensic Odontology was heightened in the latter part of 19th Century. The first formal instructional programme was given at the Armed Forces Institute of Pathology, U.S. Since then the number of cases reported has played a significant role in expanding the role of Forensic Odontology. The earliest reported case was of Lollia Paulina in the year 49 A. D. One of the early reported case is also found in India in the year 1193. In the last few decades, the basic pattern of Forensic Odontology has changed quite a lot. Advances in dental material and laboratory techniques, with improvements in scientific and photographic technology, have made the proof of presentation much to forensic science.

    In this Perspective article, I consider ways in which the contemporary arts and sciences can interact with each other, and I outline the current opportunities for funding in the United Kingdom. I examine the view that, in an art-science collaboration, it is the artist who benefits most, and I cautiously suggest that this is an oversimplification. Evidence from interviews with scientists who have been involved in these collaborations shows that artistic experience and skills are of value in the scientific research process.

  1. The role of science centres and museums in the dialogue between science and society

    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.

  8. 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.

  9. 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, 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.

    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.

    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.

  13. The need to respect nature and its limits challenges society and conservation science.

    2016-05-31

    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.

    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.

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!

    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

    The impacts of the progress in the art and science of crystal growth on human life are reviewed. Even before the invention of the transistor, quartz and corundum crystals were used as crystal oscillators and jewel bearings, respectively. However, a major impact of crystal growth on society was experienced with the invention of the transistor, which required high-purity and perfect germanium crystals. Once the importance of crystal growth was clearly recognized, the science of crystal growth also extensively developed. The growth of single crystalline silicon allows us to produce integrated circuits, which are used in all the electronic devices in everyday use. The technological developments in the growth of compound semiconductors have also had a large impact on society through the inventions of the laser diode for optical communication and the p-n junction nitride light-emitting diode toward the realization of a less energy-intensive society. The latter invention was awarded the 2014 Nobel Prize in Physics. Finally, future aspects of crystal growth are discussed.

  19. Simulating Earthquakes for Science and Society: New Earthquake Visualizations Ideal for Use in Science Communication

    2006-12-01

    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 have gained visibility via television news coverage in Southern California. These types of visualizations are becoming pervasive in the teaching and learning of concepts related to earth science. 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). Earthquakes are ideal candidates for visualization products: they cannot be predicted, are completed in a matter of seconds, occur deep in the earth, and the time between events can be on a geologic time scale. For example, the southern part of the San Andreas fault has not seen a major earthquake since about 1690, setting the stage for an earthquake as large as magnitude 7.7 -- the "big one." Since no one has experienced such an earthquake, visualizations can help people understand the scale of such an event. Accordingly, SCEC has developed a revolutionary simulation of this earthquake, with breathtaking visualizations that are now being distributed. 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.

  20. 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
