Taphonomic changes to blunt force trauma: a preliminary study

This study examines the effects of taphonomic processes on blunt force trauma (BFT) through an experimental study involving pig heads. Of particular concern is the possibility that taphonomic changes can create pseudo-trauma and/or conceal evidence of actual trauma. BFT was inflicted on 10 pig skulls using a hammer. The skulls were subsequently exposed to the environment for 12 months. Seven taphonomic changes were evaluated: the freeze-thaw cycle; rodent gnawing; carnivore scavenging; presence/weight of soil; presence/weight of rain and snow; movement/displacement of bones; and discoloration due to sun bleaching and grass staining. Taphonomic effects varied between cancellous, compact, fresh, and degreased bone. Freezing and thawing, exposure to rain and snow, movement of the skulls, and soil erosion altered and, in some cases disguised, pre-existing trauma. Rodent and carnivore activity did not obliterate evidence of BFT. Recommendations for evaluating BFT on remains affected by taphonomic processes are presented. As each taphonomic process outlined by this study has the potential to disguise antemortem injury, the authors propose that one must carefully examine large, circular openings in the skull that may represent the remnant evidence of BFT.     

High Resolution Imaging of Latent Fingerprints by Localized Corrosion on Brass Surfaces

Abstract:  The Atomic Force Microscope (AFM) is capable of imaging fingerprint ridges on polished brass substrates at an unprecedented level of detail. While exposure to elevated humidity at ambient or slightly raised temperatures does not change the image appreciably, subsequent brief heating in a flame results in complete loss of the sweat deposit and the appearance of pits and trenches. Localized elemental analysis (using EDAX, coupled with SEM imaging) shows the presence of the constituents of salt in the initial deposits. Together with water and atmospheric oxygen—and with thermal enhancement—these are capable of driving a surface corrosion process. This process is sufficiently localized that it has the potential to generate a durable negative topographical image of the fingerprint. AFM examination of surface regions between ridges revealed small deposits (probably microscopic "spatter" of sweat components or transferred particulates) that may ultimately limit the level of ridge detail analysis.     

Pore Sub‐Features Reproducibility in Direct Microscopic and Livescan Images—Their Reliability in Personal Identification

Abstract: Third level features have been reported to have equal discriminatory power as second level details in establishing personal identification. Pore area, as an extended set third level sub‐feature, has been studied by minimizing possible factors that could affect pore size. The reproducibility of pore surface area has been studied using direct microscopic and 500 ppi Livescan images. Direct microscopic pore area measurements indicated that the day on which the pore area was measured had a significant impact on the measured pore area. Pore area measurement was shown to be difficult to estimate in 500 ppi Livescan measurements owing to lack of resolution. It is not possible to reliably use pore area as an identifying feature in fingerprint examination.

醉酒驾车肇事之主观归责：故意与过失的博弈

醉酒驾车肇事的行为人在主观过错上究竟属于故意还是过失？对其进行刑事归责的主观根据何在？我国大陆刑法理论上缺乏支持,实践中亦分歧明显。以原因自由行为的讨论为前提,以责任主义为立足点,分析醉酒驾车肇事行为人刑事归责的主观根据,并对现有理论和实践中可能存在的谬误认识提出合理性怀疑,包括对该类案件如何进行主观归责作出原则性分析,甚至提出“一个主观心态可以支配一个或多个连续行为”的观点,以此得出结论,对醉酒驾车肇事的行为应当以陷入醉酒状态前的主观心态为主要根据,且适当以陷入醉酒状态之后的主观心理为辅助作综合考察,从而准确确定其肇事行为的主观归责定性根据等。

Deciding to Intervene: An Analysis of International and Domestic Influences on United States Interventions in Intrastate Disputes

Although the United States has been the most prolific intervener in the international system since the end of World War II, there has been little consensus among scholars regarding the motivations of U.S. interventions in domestic political disputes abroad. In addition, scholars do not agree on the relative effects of international factors and domestic factors on intervention decisions by the U.S. Previous research on the motivations of U.S. interventions has occurred within at least two distinctive “streams” of literature: (1) studies of state interventions; and (2) studies of the use of military force by the U.S. Hypotheses regarding U.S. interventions in intrastate disputes are derived from the previous literature, and the hypotheses are tested using recently-compiled data on intrastate disputes and U.S. interventions in intrastate disputes occurring between 1945 and 2002. The results suggest a combination of international factors, including geographic proximity and ideological linkage, significantly influence the decisions of the U.S. to intervene in intrastate disputes. The results also suggest international factors are generally more important than domestic factors, and the effects of both domestic factors and international factors on U.S. intervention decisions may differ depending on the specific type of intervention and the time period.     

International Mediation and Social Networks: The Importance of Indirect Ties

This study extends the previous literature on actors' incentives in conflict management by examining how direct and indirect links between fighting parties influence the prospects for mediation onset from a social network perspective. The paper argues, contrary to existing research, that direct links, i.e., bilateral ties between warring parties, do not notably increase the likelihood of mediation. Rather, indirect links, i.e., ties that connect two states via one or more than one third party to each other, are more likely to determine whether a conflict sees mediation. Although direct links can indicate mutual interests, shared preferences, and decreased uncertainty between the warring parties, these ties either lose importance or become cut off when states enter a conflict. By contrast, indirect ties create a social network that involves outside parties in the dispute process, and indirect ties increase the exchange of information between belligerents and potential mediators and the chances that third parties will have a vital interest in intervention. My empirical analysis using conflict and social network data in 1946–1995 provides strong support for the theory.     

Coercive Assets? Foreign Direct Investment and the Use of Economic Sanctions

How does foreign direct investment (FDI) affect the use of economic coercion? This article argues that while FDI matters, the effect depends on the entry mode of the FDI. The economic interdependence created by FDI does not have a monotonic effect on economic statecraft because the relative costs incurred by economic disruption differ depending on the forms of foreign investment. In particular, the FDI that creates wholly-owned subsidiaries (for example, cross-border mergers and aquisitions) imposes greater costs to the sender's firms than cross-border joint ventures with local partners, while FDI through joint ventures incurs greater costs for the host than the home country and its firms. By utilizing US sanction episodes from the Threat and Imposition of Economic Sanctions (TIES) dataset, the empirical analysis supports the argument. The results show that economic sanctions are less likely to occur as the share of FDI through cross-border mergers and acquisitions increases.     

Conditional on Conditionality: IMF Program Design and Foreign Direct Investment

The article explores how International Monetary Fund (IMF) program design influences foreign direct investment inflows. The author argues that stricter IMF conditionality signals a program-participating government's commitment to economic reforms, as it incurs larger ex ante political cost and risks greater ex post political cost. Thus, the catalytic effect of an IMF program is conditional on conditionality: programs with stricter conditions catalyze more foreign direct investment than those with less stringent conditions. Empirical analysis of the IMF conditionality dataset supports the argument and shows that after accounting for IMF program participation, the more structural conditions included in an IMF program, the more foreign direct investment flows into the country.
