The direct detection and identification of staining dyes from security inks in the presence of other colorants, on currency and fabrics, by laser desorption mass spectrometry

Laser desorption mass spectrometry (LDMS) is useful for the direct desorption and MS analysis of dyes off materials such as paper. Here it is shown that staining dyes, produced by currency degradation devices, such as those used by financial institutions or armored transport companies, can be detected by LDMS. These staining dye packs are commonly used in bank security programs to deter theft or unauthorized removal of currency from teller stations or from ATM cash cassettes. Working automatically, these technologies release a security dye to degrade the surface of the notes and possibly mark the assailant involved in the attack. These dyes can be characterized and identified directly from paper currency, and from fabrics, and uniquely identified in the presence of other dyes that are used in the printing and dying of such materials, by LDMS. In these experiments, no extraction step is required. A pulsed UV laser directly irradiates a paper or fabric sample--colorants are desorbed, ionized and detected using time-of-flight MS. Results shown here suggest that dyes such as Basic Red 1:1 and Basic Violet 11:1 are used in such devices.     

The influence of personal history of abuse and gender on clinicians' judgments of child abuse

Two extra-legal factors were examined for their influence on professionals' decisions to report child abuse: having been abused as a child oneself, and the gender of the child, the parent, and the professional. One hundred and one men and women who worked regularly with children in mental health settings rated a series of scenarios presented as cases from a protective service agency. Participants made several judgments regarding the case including the severity of the parent's behavior, the likely effect on the child, whether the situation was abusive, and whether the case should be reported to a social service agency. Despite some interpretive limitations, the results generally support the hypothesis that extra-legal factors influence the perceptions of professionals who are mandated to report a suspected incident of abuse.     

Equality and differentiation: Effects of group structure on allocations

Two studies using vignettes explore some conditions under which equity, equality, and need as allocation rules are taken into account by an outside allocator. Independent variables include information about success or failure of a work group, level of morale of the group, relative contributions of work group members, responsibility for outcome, and influence of one individual on others. Results suggest that differentiation based on both equity and need results from a focus on individual deserving while equality among status equals results from focus on group level factors. An interaction between outcome and contribution appears when group level factors are included; these effects also appear when there are two rather than only one target person differing from the rest of a group; an overreward effect depends on attributions of responsibility for outcome; and an influential member is seen as deserving even if a low contributor. No gender differences were found.     

The Stability of Collected Human Scent Under Various Environmental Conditions*,†

Abstract: Human scent evidence collected from objects at a crime scene is used for scent discrimination with specially trained canines. Storage of the scent evidence is usually required yet no optimized storage protocol has been determined. Storage containers including glass, polyethylene, and aluminized pouches were evaluated to determine the optimal medium for storing human scent evidence of which glass was determined to be the optimal storage matrix. Hand odor samples were collected on three different sorbent materials, sealed in glass vials and subjected to different storage environments including room temperature, ?80°C conditions, dark storage, and UVA/UVB light exposure over a 7‐week period. Volatile organic compounds (VOCs) in the headspace of the samples were extracted and identified using solid‐phase micro‐extraction–gas chromatography/mass spectrometry (SPME–GC/MS). Three‐dimensional covariance mapping showed that glass containers subjected to minimal UVA/UVB light exposure provide the most stable environment for stored human scent samples.

Regulating Assisted Reproduction in Canada,Switzerland, and the USA: Comparing the Judicialization of Policy-Making

This article analyses the extent to which courts shape policies for assisted reproduction. While the USA is considered to be the most litigious country, Canada has observed a growing involvement of the courts from the 1980s onward, and Switzerland is characterized by a modest degree of judicialization. Based on national patterns, we would expect litigation and court impact to vary across these three countries. As the empirical analysis reveals, policy-process-specific variables such as the novelty of regulation, self-regulation by key stakeholders, and the policies in place better explain the variation in the judicialization of policy-making.     

Peace building with the body: resonance and reflexivity in Colombia’s Legion del Afecto

ABSTRACT

Youth in Medellín, Colombia have been recognized as potential peacebuilders through initiatives for urban peace and non-violence, including the initiative Legión del Afecto. This paper explores the development of the Legión del Afecto in order to ask questions about the peace building potential of specific frames (e.g. coexistence) and specific strategies of mobilization (e.g. embodied). We describe how differences between the earlier and later years of the Legión have come to highlight tensions between affective versus market-based relationships in motivating youth. These tensions may be productive, but without serious attention to reflexivity, may also derail peacebuilding efforts.     

Protest Patterns in Provincial Russia: a Paired Comparison of Company Towns

Following the Soviet Union’s collapse, Russia implemented reforms aimed at transitioning to a market economy and devolving power to regional and municipal levels of government. Although it is well known that these reforms created significant uncertainty, economic crises, and protest, most existing studies do not explore the considerable variation in protest patterns across localities. This article asks why, despite similar pressures, some cities have experienced protests that are consistently larger and more intense than others. Focusing on the context of the many company towns that emerged during Soviet industrialization, I construct a paired comparison of two average-sized company towns using process tracing through interviews and archival documents. This article also employs an original protest database created through newspaper analysis that tracks not only the instances of protest but also protest size, demands, and targets. What emerges are two pathways that explain the divergent protest structures in the two company towns studied. In Cherepovets, a city that is less dependent on the central state, local elites pursued strategies of co-optation and suppression, limiting the opportunity structure for contentious politics to small-scale, local protests. In Komsomolsk-na-Amure, a city where the primary industry is in decline and dependent on support from the center, local elites converged with opposition groups to improve their bargaining position vis-à-vis the central government; this produced protests that were larger and more extreme and targeted the system as a whole.
