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.     

Can peace be purchased? A sectoral-level analysis of aid��s influence on transnational terrorism

Does foreign aid reduce terrorism? We examine whether foreign aid decreases terrorism by analyzing whether aid targeted toward certain sectors is more effective than others. We use the most comprehensive databases on foreign aid and transnational terrorism??AidData and ITERATE??to provide a series of statistical tests. Our results show that foreign aid decreases terrorism especially when targeted toward sectors, such as education, health, civil society, and conflict prevention. These sector-level results indicate that foreign aid can be an effective instrument in fighting terrorism if allocated in appropriate ways.     

Turnout as a Habit

It is conventional to speak of voting as “habitual.” But what does this mean? In psychology, habits are cognitive associations between repeated responses and stable features of the performance context. Thus, “turnout habit” is best measured by an index of repeated behavior and a consistent performance setting. Once habit associations form, the response can be cued even in the absence of supporting beliefs and motivations. Therefore, variables that form part of the standard cognitive-based accounts of turnout should be more weakly related to turnout among those with a strong habit. We draw evidence from a large array of ANES surveys to test these hypotheses and find strong support.     

Delivering Science into Public Policy: An Analysis of Murray‐Darling Basin Sustainable Yields Assessment as a Model for Impact

The desire to base policy at least in part upon scientific information is a clear trend in Australian governance. The growing literature on how to facilitate this intent highlights a few important principles complemented by examples from the application of social sciences. An example from a very large research project based on physical sciences responding to a national crisis is presented in the context of how it approached delivery to policy‐makers. The Murray‐Darling Basin Sustainable Yields Assessment, widely considered an outstanding success in both scientific terms and for its impact, is reviewed with respect to how the scientific challenge of assessing the future security of water resources in Australia's most important and politically contentious catchment translated into the policy domain. The lessons learned offer a potential template for science with policy intent.     

Sevoflurane concentrations in blood, brain, and lung after sevoflurane-induced death

Sevoflurane concentrations in blood, brain, and lung were measured in an individual apparently dying from sevoflurane inhalation. Sevoflurane is a volatile nonflammable fluorinated methyl isopropyl ether inhaled anesthetic, chemically related to desflurane and isoflurane. The incidence of abuse of sevoflurane is lower than that of other drugs of abuse possibly due to its inaccessibility to the general public and less pleasurable and addicting effects. The dead subject was an anesthetist found prone in bed holding an empty bottle of sevoflurane (Ultane). Serum, urine, and liver were screened for numerous drugs and metabolites using enzyme immunoassays and gas chromatography-mass spectrometry. Analysis did not reveal presence of any drug, including ethanol, other than sevoflurane. Sevoflurane was determined by headspace gas chromatography and revealed concentrations of 15 microg/mL in blood and 130 mg/kg in brain and lung. Autopsy revealed pulmonary edema and frothing in the lung, pathological findings associated with death by sevoflurane or hypoxia. The cause of death was ruled as sevoflurane toxicity and the manner of death as accident.     

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.     

The weakness of the strong: re-examining power in transboundary water dynamics

This article proposes a re-examination of how power is conceptualized within transboundary hydropolitics by arguing that power has been misrepresented in the water resources literature. Overemphasis on the factors of a country’s relative power, riparian position, and technological potential to exploit the resource has led to assumptions that the non-hegemon(s) is often unable to achieve their own positive outcomes and that the outcomes of interactions between hegemons and non-hegemons are predictable and detrimental. However, it appears that there are many examples that run counter to the power narrative that employs these factors. This study argues that this overemphasis neglects hegemonic vulnerabilities, which, when included with hegemonic capacities, are much more instructive in explaining transboundary water dynamics. The sources of the weakness of the strong of the alleged hegemon originates from several sources, including interlinkages between water and non-water issues, internal and external expectations, and consideration of whether the water-related issue at hand is crucial to each party’s survival or whether the party has the luxury to survive the outcome of the resolution. These factors allow for non-hegemons to achieve more favorable outcomes and, when incorporated in analysis, provide a fuller picture of the true power balance in each transboundary water interaction. We therefore call for a reconceptualization of power dynamics in transboundary waters that accounts for structural weaknesses present within all parties.     

An investigation of the relationship between anger and offence-related shame and guilt

Abstract

A number of accounts of shame and guilt emphasise an association between shame and anger difficulties, and it has been suggested that shame and rage may promote one another. The shame–anger relationship may be particularly relevant to the study of forensic populations, as the fact of having committed a criminal offence has the potential to be a highly shame-provoking experience. The current study investigates the prediction that shame and guilt reactions to an offence are differentially related to the propensity to experience and ability to control anger. A measure of offence-related shame and guilt and a measure of anger experience and control was completed by 60 men detained in forensic psychiatric units. The results supported the prediction that offence-related shame is associated with elevated levels of anger difficulties, whilst offence-related guilt is associated with ability to control anger. The findings of the current study are consistent with those of previous investigations of shame, guilt and anger. Specific implications for the understanding and prevention of violent offending are discussed.     

Fisheries management in Jamaica,international perspectives

Abstract

This paper examines Jamaica's efforts to implement of the conservation and management provisions of the United Nations Convention on the Law of the Sea (UNCLOS), bearing in mind that prior to 1982 there was an existing legal framework that sought to address issues relating to fisheries management. More specifically, the paper looks at the issues related to the conservation and management of straddling and highly migratory fish stocks under UNCLOS and subsequent agreements negotiated under the auspices of UNCLOS. It also addresses the problems Jamaica faces with the conservation and management of Queen Conch (Strombus Gigas), in particular, the UNCLOS provisions regarding access to such resource, taking into account the limitations to such access as regulated by the Convention on the International Trade in Endangered Species of Wild Fauna and Flora (CITES).
