The polymorhism of crime scene investigation: an exploratory analysis of the influence of crime and forensic intelligence on decisions made by crime scene examiners

A growing body of scientific literature recurrently indicates that crime and forensic intelligence influence how crime scene investigators make decisions in their practices. This study scrutinises further this intelligence-led crime scene examination view. It analyses results obtained from two questionnaires. Data have been collected from nine chiefs of Intelligence Units (IUs) and 73 Crime Scene Examiners (CSEs) working in forensic science units (FSUs) in the French speaking part of Switzerland (six cantonal police agencies). Four salient elements emerged: (1) the actual existence of communication channels between IUs and FSUs across the police agencies under consideration; (2) most CSEs take into account crime intelligence disseminated; (3) a differentiated, but significant use by CSEs in their daily practice of this kind of intelligence; (4) a probable deep influence of this kind of intelligence on the most concerned CSEs, specially in the selection of the type of material/trace to detect, collect, analyse and exploit. These results contribute to decipher the subtle dialectic articulating crime intelligence and crime scene investigation, and to express further the polymorph role of CSEs, beyond their most recognised input to the justice system. Indeed, they appear to be central, but implicit, stakeholders in intelligence-led style of policing.

Décision de baisser les salaires ou non: Le rôle de l'empathie face à une recommandation d'un supérieur hiérarchique (The role of Empathy in wage cut decisions).

En entreprise, les supérieurs hiérarchiques ont une influence non négligeable sur la prise de décision de leurs subordonnés. Ces derniers tendent à se conformer à l'avis de leur supérieur pour prendre leurs décisions. Toutefois, cette conformité des subordonnés à l'avis de leur supérieur peut devenir un problème lorsque l'avis reçu est questionnable d'un point de vue éthique. Les études antérieures menées à ce sujet ont démontré que le contenu n'a pas d'impact, c'est-à-dire que du moment qu'un avis est donné par un supérieur hiérarchique, les subordonnés tendent à se conformer à cet avis quelque soit son contenu. Dans la présente expérience, nous nous sommes intéressés à ce phénomène de conformité dans une prise de décision ayant des conséquences sur des personnes. En particulier, nous avons étudié le rôle de l'empathie, définit comme l'habilité de ressentir les émotions des autres ou de se mettre à leur place. Notre première hypothèse concerne l'effet principal de l'avis du supérieur : les participants tiennent compte de l'avis de leur supérieur dans leur prise de décision. Notre seconde hypothèse concerne le rôle modérateur de l'empathie: les participants haut en empathie sont moins sensibles à l'avis de leur supérieur que les participants bas en empathie étant donné qu'ils anticipent les conséquences de leur décision vis-à-vis des personnes concernées. Cent-douze étudiants ont participé à un exercice de mise en situation. Dans la peau d'un chef de Département d'une entreprise, ils devaient entre autres réfléchir au problème du niveau des salaires du personnel peu qualifié et en particulier au fait que cette catégorie de salariés était surpayée par rapport à ce qui se pratiquait sur le marché du travail. Cette expérience était composée de deux conditions, où l'avis du supérieur était manipulé. Dans la condition 1, l'avis du supérieur était de baisser les salaires, alors que dans la condition 2 l'avis était de garder les salaires constants. Les résultats ont confirmé nos hypothèses. Les participants recevant l'avis de leur supérieur de baisser les salaires ont effectivement pris la décision de baisser les salaires. Il a aussi été démontré que le niveau d'empathie modère cette relation. Les participants haut en empathie ont eu tendance à ne pas suivre l'avis donné contrairement aux participants bas en empathie. Cela démontre ainsi l'influence que peut avoir le contexte sur les individus et leur prise de décision mais aussi que les caractéristiques personnelles ont une influence non négligeable.

The determinants of contractual choice for private involvement in infrastructure projects in the United States

Reliance on private partners to help provide infrastructure investment and service delivery is increasing in the United States. Numerous studies have examined the determinants of the degree of private participation in infrastructure projects as governed by contract type. We depart from this simple public/private dichotomy by examining a rich set of contractual arrangements. We utilize both municipal and state-level data on 472 projects of various types completed between 1985 and 2008. Our estimates indicate that infrastructure characteristics, particularly those that reflect stand alone versus network characteristics, are key factors influencing the extent of private participation. Fiscal variables, such as a jurisdiction’s relative debt level, and basic controls, such as population and locality of government, increase the degree of private participation, while a greater tax burden reduces private participation.

Clean development mechanism and joint implementation in China and Russia as related to industrial energy projects

Being highly discussed the problem of climate change and global warming has been keeping importance for several of decades. As a response to the world’s need in solution for climate change disasters, the United Nations Framework Convention on Climate Change was adopted in 1992 and supplemented with the Kyoto protocol in 1997. This work is aimed to give better understanding of the Convention, Kyoto Protocol with its mechanisms and their function, related to energy projects in such case countries, as Russia and China, in order to assist evaluation of projects cost-effectiveness. It provides basic information about the Convention and the Protocol with their regulations, overview of present situation and future post-Kyoto forecasts, while the most attention is concentrated on the clean development mechanism and joint implementation step-by-step project cycles and specific regulations in given countries. The current study disclosed that CDM and JI project cycles are resulting in a complicated process. By the moment it requires step-by-step following of a number of methodologies, spending time and finance to particular project development. Uncertainties about post-Kyoto period bring additional risk to the projects and complicate any business decision concerning Kyoto Protocol.

Competition in notch signaling with cis enriches cell fate decisions

Notch signaling is involved in cell fate choices during the embryonic development of Metazoa. Commonly, Notch signaling arises from the binding of the Notch receptor to its ligands in adjacent cells driving cell-to-cell communication. Yet, cell-autonomous control of Notch signaling through both ligand-dependent and ligand-independent mechanisms is known to occur as well. Examples include Notch signaling arising in the absence of ligand binding, and cis-inhibition of Notch signaling by titration of the Notch receptor upon binding to its ligands within a single cell. Increasing experimental evidences support that the binding of the Notch receptor with its ligands within a cell (cis-interactions) can also trigger a cell-autonomous Notch signal (cis-signaling), whose potential effects on cell fate decisions and patterning remain poorly understood. To address this question, herein we mathematically and computationally investigate the cell states arising from the combination of cis-signaling with additional Notch signaling sources, which are either cell-autonomous or involve cell-to-cell communication. Our study shows that cis-signaling can switch from driving cis-activation to effectively perform cis-inhibition and identifies under which conditions this switch occurs. This switch relies on the competition between Notch signaling sources, which share the same receptor but differ in their signaling efficiency. We propose that the role of cis-interactions and their signaling on fine-grained patterning and cell fate decisions is dependent on whether they drive cis-inhibition or cis-activation, which could be controlled during development. Specifically, cis-inhibition and not cis-activation facilitates patterning and enriches it by modulating the ratio of cells in the high-ligand expression state, by enabling additional periodic patterns like stripes and by allowing localized patterning highly sensitive to the precursor state and cell-autonomous bistability. Our study exemplifies the complexity of regulations when multiple signalng sources share the same receptor and provides the tools for their characterization.

Voting advice applications : impact on voting decisions in the 2011 Swiss national elections

In most democracies voting Advice Applications (VAAs) advising citizens which candidate or party they should vote for become more and more popular. It is therefore crucial to know more about the functioning and the effects of such tools. After some general remarks about the spread of these tools and their possible effects gathered so far in various studies, this paper presents the latest results from a research conducted in the course of the 2011 Swiss national elections. They confirm that VAAs can lead to better informed voters and are likely to have a positive impact on electoral turnout. Additionally it can be shown that the Swiss VAA smartvote made voters change their voting intention and that they voted for a different party. This was particularly advantageous for the Green Liberal Party. At the moment, only a minority of voters rely on the voting recommendation by smartvote. This might change dramatically with the introduction of e-voting. Once people can vote electronically, there are hardly any possibilities to prevent voters from transferring their selection of candidates based on the recommendation given by a VAA into the official electronic ballot paper. If this is possible, e-voting will become more popular than postal voting.

International survey of acute stroke imaging used to make revascularization treatment decisions.

BACKGROUND: To assess the differences across continental regions in terms of stroke imaging obtained for making acute revascularization therapy decisions, and to identify obstacles to participating in randomized trials involving multimodal imaging. METHODS: STroke Imaging Repository (STIR) and Virtual International Stroke Trials Archive (VISTA)-Imaging circulated an online survey through its website, through the websites of national professional societies from multiple countries as well as through email distribution lists from STIR and the above mentioned societies. RESULTS: We received responses from 223 centers (2 from Africa, 38 from Asia, 10 from Australia, 101 from Europe, 4 from Middle East, 55 from North America, 13 from South America). In combination, the sites surveyed administered acute revascularization therapy to a total of 25,326 acute stroke patients in 2012. Seventy-three percent of these patients received intravenous (i.v.) tissue plasminogen activator (tPA), and 27%, endovascular therapy. Vascular imaging was routinely obtained in 79% (152/193) of sites for endovascular therapy decisions, and also as part of standard IV tPA treatment decisions at 46% (92/198) of sites. Modality, availability and use of acute vascular and perfusion imaging before revascularization varied substantially between geographical areas. The main obstacles to participate in randomized trials involving multimodal imaging included: mainly insufficient research support and staff (50%, 79/158) and infrequent use of multimodal imaging (27%, 43/158) . CONCLUSION: There were significant variations among sites and geographical areas in terms of stroke imaging work-up used tomake decisions both for intravenous and endovascular revascularization. Clinical trials using advanced imaging as a selection tool for acute revascularization therapy should address the need for additional resources and technical support, and take into consideration the lack of routine use of such techniques in trial planning.

The use of mini-projects in an undergraduate laboratory course in chemistry

This paper reports the results of a three-year study of the effectiveness of mini-projects in a first year laboratory course in chemistry at a Scottish university. A mini-project is a short, practical problem which requires for its solution the application of the knowledge and skills developed in previously completed set experiments. A number of recommendations have been made about the most appropriate ways of introducing mini-projects into undergraduate laboratory course. The main hypothesis of this survey was concerned with the value of mini-projects in laboratory courses formulated within the context of Information Processing Theory.

When decisions of others matter to me: an electrophysiological analysis.

Background: Actions of others may have immediate consequences for oneself. We probed the neural responses associated with the observation of another person"s action using event-related potentials in a modified gambling task. In this task a"performer" bet either a higher or lower number and could win or lose this amount. Three different groups of"observers" were also studied. The first (neutral) group simply observed the performer"s action, which had no consequences for the observers. In the second (parallel) group, wins/losses of the performer were paralleled by similar wins and losses by the observer. In the third (reverse) group, wins of the performer led to a loss of the observer and vice versa. Results: ERPs of the performers showed a mediofrontal feedback related negativity (FRN) to losses. The neutral and parallel observer groups did similarly show an FRN response to the performer"s losses with a topography indistinguishable from that seen in the performers. In the reverse group, however, the FRN occurred for wins of the performer which translated to losses for the observer. Conclusions: Taking into account previous experiments, we suggest that the FRN response in observers is driven by two evaluative processes (a) related to the benefit/loss for oneself and (b) related to the benefit/loss of another person

The Role of Firm Size in Training Provision Decisions: evidence from Spain

The level of training provided by small firms to their employees is below that provided by their larger counterparts. The provision of firm-related training is believed to be associated to certain characteristics of the firm. In this paper we argue that small firms provide fewer training opportunities as they are less likely to be associated with these characteristics than large firms. The suitability of estimating training decisions as a double-decision process is examined here: first, a firm has to decide whether to provide training or not and, second, having decided to do so, the amount of training to provide. The differences in training provision between small and large firms are decomposed in order to analyse the individual contribution of these characteristics to explaining the gap. The results show that small firms face greater obstacles in accessing training and that the main reasons for that are related to their technological activity and the geographical scope of the market in which they operate.

Estratègies de cura i presa de decisions en persones grans amb dependència ingressades en una unitat geriàtrica d'atenció intermèdia : estudi descriptiu

Aquest estudi té com objectiu observar les relacions entre les estratègies de cura (formal, informal, mixta) que fan servir els cuidadors de persones grans dependents, la seva situació social i les seves motivacions per la decisió respecte a com fan la cura. L’estat del tema destaca el predomini de les cures informals sobre les formals en els models de benestar mediterranis i la rellevància de la interacció entre factors personals socioculturals i les polítiques socials en la presa de decisions individuals sobre la cura de la dependència. La llei de la dependència, de recent implementació a l’Estat espanyol, ha universalitzat l’accés als recursos formals, creant un nou paradigma d’interacció cuidadors-recursos. Es tracta d’un estudi observacional, transversal, descriptiu de tipus mixt quantitatiu/qualitatiu realitzat a partir d’entrevistes individuals als cuidadors de dependents ingressats en una unitat geriàtrica d’atenció intermèdia. Es recullen dades sobre el context sociofamiliar, l’estratègia de cura, l’autopercepció i les motivacions. Els resultats mostren que els cuidadors combinen prestacions econòmiques i serveis (públics i privats) per adaptar al màxim l’estratègia a les condicions del dependent i a les seves pròpies. Tenen la convicció generalitzada que l’atenció cal fer-la al domicili per motius de reciprocitat i respecte a la persona cuidada. El pas a l’atenció residencial és una decisió molt difícil pels cuidadors. La implantació de la llei de la dependència ha normalitzat la relació entre cuidadors i recursos formals, però la burocratització i la insuficiència de l’oferta de serveis no afavoreixen canvis substancials en la provisió de l’ajut, que continua essent majoritàriament informal. La millora en la percepció de continuïtat d’atenció entre el domicili i la residència, i també en la gestió i l’oferta de serveis formals públics es presenten com a reptes de treball importants al nostre país.

Introducing Continuous Integration for C and C++ Software Development Projects on Linux Platform

Software integration is a stage in a software development process to assemble separate components to produce a single product. It is important to manage the risks involved and being able to integrate smoothly, because software cannot be released without integrating it first. Furthermore, it has been shown that the integration and testing phase can make up 40 % of the overall project costs. These issues can be mitigated by using a software engineering practice called continuous integration. This thesis work presents how continuous integration is introduced to the author's employer organisation. This includes studying how the continuous integration process works and creating the technical basis to start using the process on future projects. The implemented system supports software written in C and C++ programming languages on Linux platform, but the general concepts can be applied to any programming language and platform by selecting the appropriate tools. The results demonstrate in detail what issues need to be solved when the process is acquired in a corporate environment. Additionally, they provide an implementation and process description suitable to the organisation. The results show that continuous integration can reduce the risks involved in a software process and increase the quality of the product as well.

Laboratory projects using inquiry-based learning: an application to a practical inorganic course

This paper reports how laboratory projects (LP) coupled to inquiry-based learning (IBL) were implemented in a practical inorganic chemistry course. Several coordination compounds have been successfully synthesised by students according to the proposed topics by the LP-IBL junction, and the chemistry of a number of metals has been studied. Qualitative data were collected from written reports, oral presentations, lab-notebook reviews and personal discussions with the students through an experimental course with undergraduate second-year students at the Universidad Nacional de Colombia during the last 5 years. Positive skills production was observed by combining LP and IBL. Conceptual, practical, interpretational, constructional (questions, explanations, hypotheses), communicational, environmental and application abilities were revealed by the students throughout the experimental course.
