The influence of camera-to-object distance and focal length on the representation of faces

When one thinks of the so-called barrel or wide-angle distortion, grotesquely warped faces may come to mind. For less extreme cases with primarily inconspicuous facial proportions, the question, however, still arises whether there may be a resulting impact on the identification of faces. In the first experiment, 3 test persons were photographed at a fixed camera-to-object distance of 2 m. In the second experiment, 18 test persons were each photographed at a distance of 0.5 m and 2.0 m. For both experiments photographs were taken from a fixed angle of view in alignment with the Frankfurt Plane. An isolated effect of the focal length on facial proportions could not be demonstrated. On the other hand, changes in the camera-to-object distance clearly influenced facial proportions and shape. A standardized camera-to-object distance for passport photos, as well as reconstruction of the camera-to-object distance from crime scene photos and the use of this same distance in taking photographs for comparison of suspects are called for. A proposal to refer to wide-angle distortion as the nearness effect is put forward.     

The Changing Face of Corporate Liability – New Hard Law and the Increasing Influence of Soft Law

The first frameworks defining standards of human rights protection specifically for business enterprises were non-binding “soft law” like the UN Guiding Principles on Business and Human Rights. In recent times, a “hardening” of corporate human rights law has taken place. Several acts of “hard law” have been implemented at a national and EU level. This article provides an overview of the most important ones. The “hard law” provisions differ in their scope: some obligate companies to report on human rights, others stipulate concrete obligations to conduct human rights due diligence. Another way of tackling the issue of human rights compliance has been demonstrated by the prosecution of companies in the United States. While procedural guidelines abstractly stipulate an effective compliance system to be a mitigating factor, the US Department of Justice regularly defines concrete compliance obligations in deferred or non-prosecution agreements. This development could lead to comprehensive liability for negligence due to organisational and monitoring deficiencies. But who defines the standards? This article examines how the changing practice of human rights compliance may have “feedback effects” on hard law, particularly by changing the scale of negligence. Regarding the lack of effectiveness of some due diligence measures, especially in the “certification industry”, it is then asked how legislation may proactively exert influence by defining effective CSR instruments necessary to prevent civil and criminal liability. Using the example of German law, a proposal is made to implement an obligation of human rights due diligence in “hard law” and, simultaneously, set up an independent expert commission that drafts guidelines specifying the necessary measures for different kinds of companies.     

Entomological and Cardiologic Evidence of Time Since Death in Short Postmortem Intervals

Estimating the time since death of the deceased is a main goal in forensic investigations, but this can be challenging due to contradictory results derived from different investigations at the scene of death. We present a case of a 78‐year‐old woman, found dead in a small forest with broad‐leaved trees, whose husband had a history of domestic violence. Routinely performed investigations, such as postmortem rectal temperature and lividity, yielded inconsistent time since death results between only a few and longer than 20 h. This difficulty was most likely caused by high ambient temperatures of up to 38.0°C, which negatively influenced the informative value of the applied nomogram method. Additionally, performed entomological investigation of fly maggots (Lucilia illustris) recovered from the corpse and the assessment of heart pacemaker data revealed consistent and incontrovertible results. The presented case highlights the benefits of information provided by entomological investigations and data evaluation of cardiac implantable electronic devices and the combined use of the two techniques.     

Political Involvement and the Development of Political Attitudes

Political socialization research so far has focused primarily on the direction of attitudes among children and youngsters. The preconditions for the development of political attitudes among these age groups have been neglected. In theoretical discussions cognitive development has been offered as a major prerequisite. In the article it is posited that political involvement is a second major prerequisite.
The effects of political involvement are examined with respect to four aspects of political attitudes among Danish school children: the ability to express attitudes, the correlation between indicators of a particular attitude, the stability of attitudes, and the correlation between different attitudes. Except for the stability of attitudes, results are clear. Political involvement is related to the formation of attitudes. The effect of political involvement is stronger than the effect of any of the traditional socio-economic variables ordinarily considered in socialization research.     

Policy Networks And Agricultural Policy Reforms: Explaining Deregulation In Sweden And Re‐Regulation In The European Community

Policy network analysis has been criticized for being unable to explain outcomes and change in outcomes. This article develops a theoretical network model which attempts to explain reform outcomes. It suggests that the success of reformers depends mainly on the policy network type existing in the sector in which they attempt to bring about change. If the network has a high degree of cohesion, then those network members who are subject to reform have power to defend the principles of the established policy. Consequently, only moderate policy reform occurs. On the other hand, if the network's degree of cohesion is low, then those who are subject to reform do not have the power to oppose reformers successfully. Therefore, reformers have opportunities to bring about fundamental policy reform. Differences in the cohesion of agricultural policy networks help to explain why the 1990 Swedish agricultural policy reform was more radical than the European Community's in 1992.     

Try Federalism

The present article follows up a previous study (Anckar 1998) which showed a strong association between size and party system fragmentation. The aim of the article is to see whether the explanatory power of size can, in fact, be attributed to a federal form of government. 77 countries with free party systems constitute the research population. The dependent variable has three components: number of parties, electoral support for the leading party, and the 'effective number of parties' calculated according to the Laakso-Taagepera formula. Preliminary tests reveal that federal states have a more fragmented party system than unitary states. However, when controlling for size, electoral system, the 'effective threshold,' and presidentialism, the results clearly show that federalism is overshadowed by size and also, to a lesser extent, by the effective threshold.     

Quangos—What's in a Name? Defining Quangos from a Comparative Perspective

Without definitional clarity the "quango debate" is inherently flawed and meaningful progress undermined. A possible solution to this problem is proposed in this article by way of a subsectional map which aims to clarify the quango topography. This accepts the diversity inherent in the quango debate while allowing for increased clarity and focused research. This, the authors believe, is the only way forward for practitioners, academics and policymakers working within the sphere of quasi-government. There is a need to address precise forms or subsections of the quango continuum as studies or reforms which focus on one type of quango would not necessarily work if applied to all quangos, or quangos in other countries.
