Multimodal biometrics for identity documents (MBioID)

The MBioID initiative has been set up to address the following germane question: What and how biometric technologies could be deployed in identity documents in the foreseeable future? This research effort proposes to look at current and future practices and systems of establishing and using biometric identity documents (IDs) and evaluate their effectiveness in large-scale developments. The first objective of the MBioID project is to present a review document establishing the current state-of-the-art related to the use of multimodal biometrics in an IDs application. This research report gives the main definitions, properties and the framework of use related to biometrics, an overview of the main standards developed in the biometric industry and standardisation organisations to ensure interoperability, as well as some of the legal framework and the issues associated to biometrics such as privacy and personal data protection. The state-of-the-art in terms of technological development is also summarised for a range of single biometric modalities (2D and 3D face, fingerprint, iris, on-line signature and speech), chosen according to ICAO recommendations and availabilities, and for various multimodal approaches. This paper gives a summary of the main elements of that report. The second objective of the MBioID project is to propose relevant acquisition and evaluation protocols for a large-scale deployment of biometric IDs. Combined with the protocols, a multimodal database will be acquired in a realistic way, in order to be as close as possible to a real biometric IDs deployment. In this paper, the issues and solutions related to the acquisition setup are briefly presented.     

Thermal requirements of immature stages of Chrysomya albiceps (Diptera: Calliphoridae) as a common forensically important fly

Entomological material may be used to estimate the time since death occurred (postmortem interval, PMI) in forensically obscure cases. The method that is commonly used to calculate minimum post-mortem interval (mPMI, i.e., the least amount of time since one can be confident death occurred) is based on the relationship between insect development and ambient temerature. Isomegalen and isomorphen diagrams are among methods allowing to calculate the age of necorphagous insects, yet thermal summation models provide the most precise and acurate estimations. The digrams are prepared based on the length or the developmental stages of the larvae as a function of time and mean ambient temperature. A knowledge of thermal requirements, in particular lower temperature threshold (D_z) at which development of a species terminates, is of essential importance to calculate ADD (Accumulated Degree Days). In this study different temperature regimes were used to construct the isomorphen diagram, examinate changes in larval body length at different ambient temperatures and to estimate the thermal requirements for developemnt of Chrysomya albiceps, the most common dipteran species reported on human and animal cadavers in Iran. Six development events including hatching, 1st ecdysis, 2nd ecdysis, wandering, pupariation and eclosion were studied under eleven constant temperature regims (17–37 ⁰C). The development rate of Ch. albiceps increased as temperature increased. The larval length peaked at the end of third stage and then decreased at wandering stage. The maximum larval length occurred at 72 h post oviposition at either 31, 33, or 35 °C. At 17 °C, larvae did not hatch from eggs and at 37 °C wandering larvae did not proceed to pupariation, and thus larval development were analysed at the nine left over temperatures. The development stages required at least (D_z ± SE) 13.04 ± 0.37, 14.29 ± 0.45, 15.69 ± 0.56, 15.18 ± 0.56, 14.94 ± 0.48, and 11.23 ± 0.41 °C to reach one of the successive developmentl events, respectively. The estimated thermal summation constant (k) for those the six events were 10.43 ± 0.27, 19.31 ± 0.32, 27.87 ± 1.3, 55.94 ± 1.82, 66.69 ± 3.5, and 143.52 ± 5.61 ADD accordingly.     

Getting Down to Basics: A Situated Model of Conflict in Social Relations

The field of conflict resolution is fractured. Despite many decades of fine research, we still lack a basic unifying framework that integrates the many theories of conflict dynamics. Thus, the findings from research on conflict are often piecemeal, decontextualized, contradictory, or focused on negative outcomes, which contributes to a persistent research‐practice gap. In this article, we describe a situated model for the study of conflict that combines separate strands of scholarship into a coherent framework for conceptualizing conflict in dyadic social relations. The model considers conflict interactions in the context of social relations and employs prior research on the fundamental dimensions of social relations to create a basic framework for investigating conflict dynamics. The resulting model is heuristic and generative. We discuss the theoretical context and main propositions of this model as well as its implications for conflict resolution practitioners.     

Moderators and Mediators of Framing Effects in Political Marketing: Implications for Political Brand Management

Due to its important practical implications, there has been a growing number of studies on framing conducted by scholars from various research domains. There has been, however, no paper that would provide a comprehensive overview of various moderators and mediators of the effect. The aim of this paper is to address this research gap, concentrating on psychological moderators and mediators of framing characteristic for political marketing. The paper consists of three parts. In the first part, the concepts of framing, priming and agenda-setting as well as the similarities and differences between them are presented in order to resolve common terminological inconsistencies. In the second, we discuss the moderating role of such variables as knowledge, trust in media and values on framing effect. In the third section, psychological mechanisms that underlie framing and priming are reviewed. Here, cognitive mediators such as accessibility and applicability effects are presented, followed by the discussion of the moderating and mediating role of emotions in framing effects, with special attention given to positive-negative asymmetry observed in the evaluation of political candidates and events. Finally, implication for political brand management are discussed. Our findings can be relevant for politicians, specialists dealing in political brand image and scholars studying framing effects.     

The macro and micro views of political marketing: the underpinnings of a theory of political marketing

The multi‐disciplinary nature of political marketing lends itself to a micro/macro analysis. The goal of the article is to present the theoretical frames allowing one to develop an approach to political marketing, which may become the foundations of a general theory of political marketing. Like microeconomics and macroeconomics are the two major categories within the field of economics, so are micro and macro approach to political marketing the two major perspectives that allow one to better understand the workings of modern democracies and the processes taking place there. Such an approach can integrate various theories of particular political behavior considered as part of an external macrostructure, understood as broad social, political, legal, economic, and technological context, with the theories of political behavior of individuals and institutions considered as internal microstructure.
