A Systematic Study to Understand the Effects of Particle Size Distribution of Magnetic Fingerprint Powders on Surfaces with Various Porosities

This study intends to design magnetite (Fe₃O₄)‐based magnetic fingerprint powders with different particle size distributions. It also investigates the influence of particle size distribution on the visualization of latent fingermarks with as little background staining as possible on the surfaces with various porosities in a systematic way. Two strategies were used to prepare the magnetic fingerprint formulations for this study: milling of coarse magnetite particles for different durations, and mixing of sieved fine particles with different size ranges with coarse particles. Particle size analyses of the prepared magnetic powders, optical microscopy‐based roughness analysis of the surfaces and SEM measurements of the visualized fingerprints and representative powders were performed. Mag2 of the formulations prepared through milling and Mag5 and Mag6 of the formulations prepared through sieving and mixing were more successful in the development of latent prints than the rest of the solutions.     

The Question of Ottoman Ignorance before the Morea Rebellion of 1770: A Challenge to Widely Accepted Belief in the Light of New Ottoman Documents

Most early Ottoman and European sources take it for granted that the Ottoman Empire was either indifferent to or unaware of the Russian intrigues going on in the Morea and therefore did not take any measures against Russia prior to the insurrection of 1770. Recent writings on this uprising do not really add anything to the discussion, simply accepting the Ottoman ignorance suggested by early Ottoman and European scholars. In the light of newly discovered archival sources this article submits that blaming the entire bureaucracy for a total ignorance of Russian intrigues or denying any possibility that the Russians might appear in the Mediterranean Sea is simply without foundation. Our archival documents contradict any allegation claiming that all Ottoman statesmen who were in charge of the empire at the time were ignorant. Instead, these sources indicate that some of the Ottoman statesmen took necessary precautionary measures (both in the Morea and many other regions under Ottoman domination) long before the coming of the Russians, which can be seen as proof of their awareness.

The 2012 Elections in Mexico: The Birth of a Consolidated Federal Democracy?

In 2012, the simultaneous elections at the federal, state and municipal levels in Mexico reopened the debate about the path of democratic consolidation in the country. With the return of the Revolutionary Institutional Party to the presidency in 2013, there are renewed signs that Mexican democratic consolidation is underway. Particularly important in this process is that the 2012 gubernatorial and mayoral elections have been more competitive, resulting in higher political alternation in power between political parties. Under a changing subnational political context, there are indications that subnational politicians are no longer under the shadow of a dominant party system. As a more consolidated federal democracy, the political landscape in Mexico has become more complex.

公司集资类犯罪中的共同犯罪问题研究

以公司为主体实施的集资类犯罪的客观行为一般比较复杂,存在多人共同实施、多环节分担实施的现象,司法实践中存在两个方面的问题：一是主观方面从证据上难以证明部分员工对公司的集资犯罪存在直接故意,其犯罪主观故意难以认定;二是公司员工之间的分工比较明确,个别员工实施的行为从外观来看,几乎与公司所从事的集资犯罪没有明显的关联,其共同犯罪行为也难以认定.但他们的行为却对公司的集资犯罪具有促成和加工作用,具有严重的社会危害性.解决这两个问题的理论出路在于,主观上可以引进间接故意理论来解决部分行为人的主观故意的认定,客观上采取“同心一体说”来解决其共同犯罪行为的认定.     

司法鉴定管理是社会管理与公共服务的统一

一、时代背景 历史的发展表明,当一个国家或者地区的人均GDP达到3000美元左右的时期,是社会矛盾冲突最为严重的时期,即所谓中等发达国家陷阱或拉美现象。自3000美元到1万美元这一阶段将面对崛起的困境：自然资源困境、社会冲突加剧、心理困境、道德困境、民族矛盾、国际竞争等。当前,我国也正处于3000美元向1万美元过渡的社会转型期,各种社会矛盾表现出复杂性、尖锐性、群体性和多发性。     

Automated region segmentation on cartridge case base

One of the significant problems encountered in criminology studies is the successful automated matching of fired cartridge cases, on the basis of the characteristic marks left on them by firearms. An intermediate step in the solution of this problem is the segmentation of certain regions that are defined on the cartridge case base. This paper describes a model-based method that performs segmentation of the cartridge case using surface height image of a center fire cartridge case base. The proposed method detects the location of the cartridge case base center and specific circular contours around it iteratively by projecting the problem to a one-dimensional feature space. In addition, the firing pin impression region is determined by utilizing an adaptive threshold that differentiates impression marks form primer region surface. Letters on the cartridge case base are also detected by using surface modeling and adaptive thresholding, in order to render the surface comparison operation robust against irrelevant surface features. Promising experimental results indicate the eligibility of the proposed method to be used for automated cartridge case base region segmentation process.
