Built-in Safeguards and the Implementation of Civil War Peace Accords

This article contributes to analyses of peace agreement implementation by focusing on the role of built-in safeguards as procedural mechanisms within peace agreements. Recent empirical studies suggest that negotiated peace agreements are a frequent mode of armed conflict termination and implementation of those agreements to be the primary predictor of enduring peace and the quality of that peace. However, in many instances implementation takes years or even decades and is subject to breakdown before achieving the key implementation objectives. In this article, we identify and theorize three key safeguards in peace accords: transitional power-sharing, dispute resolution, and verification mechanisms. We argue that these safeguards lead to higher implementation of provisions negotiated in peace agreements by addressing mutual suspicion and by facilitating more constructive working relationships among former rivals. To test our arguments, we analyze implementation of comprehensive peace agreements negotiated between 1989 and 2012 from the Peace Accords Matrix Implementation Data (PAM_ID). We find that the built-in safeguards that we have identified significantly explain variations in levels of peace agreement implementation.

There’s an app for that: Modernizing domestic violence support through the creation of new technologies,tools, and services

With domestic violence (DV) at an all-time high, police departments are drastically underutilizing technology to combat DV. Currently, New York police departments complete a “Domestic Incident Report” at the scene of domestic incidents but fail to adequately facilitate support services. New York State should mandate a services component into police DV protocols, specifically by commissioning: (1) an application linked to DV organizations presented at the scene of domestic incidents; and (2) a gateway application to refer victims to the correct services. Such tools would allow for the rendering of more efficient support to DV victims in times of immediate crisis.     

Carbon‐Based Fingerprint Powder as a One‐Step Development and Matrix Application for High‐Resolution Mass Spectrometry Imaging of Latent Fingerprints

Carbon‐based materials are often used as matrices for matrix‐assisted laser desorption/ionization mass spectrometry (MALDI‐MS) and its imaging (MALDI‐MSI). However, researchers have refrained from using carbon‐based fingerprint powder (CFP) as a matrix due to high background and contamination. In this work, the compatibility of CFP is reevaluated with MALDI‐MSI using a high‐resolution mass spectrometer (HRMS) and compared to traditional organic matrices. Relevant fingerprint compounds were easily distinguished from carbon cluster peaks when using HRMS. For fair comparison, half of a fingerprint was dusted with CFP while the other half was dusted with traditional organic matrices. All compounds studied had comparable, or higher, signal‐to‐noise (S/N) ratios when CFP was used as the matrix. Additionally, chemical image qualities closely followed the trend of S/N ratios. CFP proved to be an effective one‐step development and matrix application technique for MALDI‐MSI of latent fingerprints, when carbon cluster peaks are well separated by a HRMS.     

Application of MALDI‐TOF MS for Estimating the Postmortem Interval in Rat Muscle Samples

Estimating the postmortem interval (PMI) is very important in the forensic sciences. Although many approaches have been used for estimating the PMI, accurate PMI calculations are still difficult. In this study, four Sprague Dawley (SD) rats were sacrificed by suffocation, and muscle samples were collected by dissection at various time intervals (0, 48, 96, and 144 h) after death. All samples were probed using matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOFMS) to obtain molecular images and data for principal component analysis (PCA). The results showed that the peaks at m/z 1511, 1543, 1564, 1586 clearly decreased in intensity from 0 to 144 h postmortem and that the time groups were separated from each other on the PCA score plot. The prediction model showed high recognition capability (95.93%) and cross‐validation (83.72%). Our work suggests that MALDI‐TOF MS can be used to determine the PMI.     

莲花县是创建井冈山革命根据地的策源地

随着党史学界特别是江西学者对秋收起义和井冈山革命根据地创建这段历史资料的不断挖掘和对历史史实的不断考证,莲花县在创建井冈山革命根据地中的历史作用得到新的认识。通过对文家市、宾兴馆、古城会议内容分析,中共江西省委书记汪泽楷对秋收起义前敌委员会的指示信,还有目前没有文献史料推翻的宋任穷的回忆,可以得出＂引兵井冈＂的重大决策是在莲花宾兴馆会议作出的结论。充分认识莲花县在中国革命中的历史地位,对于正确认识毛泽东的决策方法,大力发掘莲花县的红色资源,具有重要意义。     

Effect of Aging and Surface Interactions on the Diffusion of Endogenous Compounds in Latent Fingerprints Studied by Mass Spectrometry Imaging,

The ability to determine the age of fingerprints would be immeasurably beneficial in criminal investigations. We explore the possibility of determining the age of fingerprints by analyzing various compounds as they diffuse from the ridges to the valleys of fingerprints using matrix‐assisted laser desorption/ionization mass spectrometry imaging. The diffusion of two classes of endogenous fingerprint compounds, fatty acids and triacylglycerols (TGs), was studied in fresh and aged fingerprints on four surfaces. We expected higher molecular weight TGs would diffuse slower than fatty acids and allow us to determine the age of older fingerprints. However, we found interactions between endogenous compounds and the surface have a much stronger impact on diffusion than molecular weight. For example, diffusion of TGs is faster on hydrophilic plain glass or partially hydrophilic stainless steel surfaces, than on a hydrophobic Rain‐x treated surface. This result further complicates utilizing a diffusion model to age fingerprints.
