Direct Analyte‐Probed Nanoextraction Coupled to Nanospray Ionization–Mass Spectrometry of Drug Residues from Latent Fingerprints

Here, we present a method of extracting drug residues from fingerprints via Direct Analyte‐Probed Nanoextraction coupled to nanospray ionization–mass spectrometry (DAPNe‐NSI‐MS). This instrumental technique provides higher selectivity and lower detection limits over current methods, greatly reducing sample preparation, and does not compromise the integrity of latent fingerprints. This coupled to Raman microscopy is an advantageous supplement for location and identification of trace particles. DAPNe uses a nanomanipulator for extraction and differing microscopies for localization of chemicals of interest. A capillary tip with solvent of choice is placed in a nanopositioner. The surface to be analyzed is placed under a microscope, and a particle of interest is located. Using a pressure injector, the solvent is injected onto the surface where it dissolves the analyte, and then extracted back into the capillary tip. The solution is then directly analyzed via NSI‐MS. Analyses of caffeine, cocaine, crystal methamphetamine, and ecstasy have been performed successfully.     

A New Method for Determination of Postmortem Interval: Citrate Content of Bone*

Abstract: Few accurate methods exist currently to determine the time since death (postmortem interval, PMI) of skeletonized human remains found at crime scenes. Citrate is present as a constituent of living human and animal cortical bone at very uniform initial concentration (2.0 ± 0.1 wt %). In skeletal remains found in open landscape settings (whether buried or not), the concentration of citrate remains constant for a period of about 4 weeks, after which it decreases linearly as a function of log(time). The upper limit of the dating range is about 100 years. The precision of determination decreases slightly with age. The rate of decrease appears to be independent of temperature or rainfall but drops to zero for storage temperature <0°C.     

State and Non-State Alliances in the Middle East

Proxy relationships between non-state challengers and their external state patrons in the Middle East are a factor that can weaken regional stability as non-state proxies become both a tool and a decisive factor in shaping inter-state competition between regional powers. As a result, non-state actors with regional influence must increasingly be factored into policy decisions in military, diplomatic and legal terms.     

En-Gendering the Sublime: Aesthetics and Politics in the Eighteenth Century

In this essay I expand on the analysis of the en-gendered sublime, an aesthetic concept of political consequence used in the eighteenth century. In a discussion of the initial phase of modern aesthetics I will present Immanuel Kant's opinions on the sublime's ennobling effect as having solely male connotations. This, I argue, became an important part of the construction of a new notion of citizenship on the basis of nationality and as an exclusively male domain. Furthermore, I will claim that conceptions of the “bad” sublime, as expressed by thinkers such as Edmund Burke, made up another side of this ennobling sublimity coin, which was the politically provocative defined in female terms. Aesthetics has obviously walked hand-in-hand with politics ever since Plato's Republic, and the concept of the sublime only make up a small part of this complex union—but undeniably a rather interesting one.     

Tale of Transgression: Charlie and the Representation of Female Homosexuality in Interwar Sweden

The first Swedish novel with a female homosexual protagonist, Charlie, was published in 1932, and this essay focuses on an analysis of three topoi in it, namely “the unveiling of a secret”, “the triangle of desire”, and “the scene at the mirror”. These topoi correspond to prevalent cultural representations of female homosexuality in the interwar period, under the headings of the three Ms: Masculinity, Mothering, and Mirrors, respectively. The main points of reference in the analysis are taken from sexology, psychoanalysis, and Radclyffe Hall's novel The Well of Loneliness, but it is argued that the narrative of Charlie transcends the restraining categories and normative classifications it presents.     

Hope in Context: Developmental Profiles of Trust,Hopeful Future Expectations,and Civic Engagement Across Adolescence

Hopeful expectations for the future have been shown to play an important role in the positive development of youth, including youth contributions to society. Although theory and some research suggest that familial socialization may influence future-oriented cognitions, little work has focused on the possible interrelation of parent–child relationships and the development of hope, particularly during adolescence. Accordingly, the first goal of this study was to identify developmental profiles of youth with respect to hopeful future expectations (HFE) and parental trust across adolescence. Next, we explored whether these developmental trajectories were related to youth Contribution, indexed by community leadership, service, and helping attitudes and behaviors. We used growth mixture modeling to simultaneously examine trajectories of adolescents’ perceived connections with parents (indexed by parent trust) and HFE among 1,432 participants (59 % female) from Waves 3 through 6 (Grades 7 through 10) of the 4-H Study of Positive Youth Development. A four-profile model provided the best fit to the data, with the following profiles: Moderate HFE/U-shaped Trust; Moderate HFE/Increasing Trust; Both Decreasing; and Both High Stable profiles. We then explored whether hope-trust profiles were related to youth Contribution in Wave 7. Contrary to hypotheses, results indicated that the profile reflecting the greatest discrepancy in HFE and trust across early to middle adolescence (i.e., Moderate Hope/U-shaped Trust) was associated with the highest mean Contribution scores. The implications of the findings for future theory and research are discussed.

Adolescent Risk Behavior Subgroups: An Empirical Assessment

Theories and prior research have outlined a constellation of adolescent risk behaviors that tend to co-occur, reflecting a general pattern. Although their generality has largely been supported, there is some question about how to best study and portray the relationship among these behaviors. This study used data from a survey administered to high school youth (n = 2549, 38 schools). The general population sample comprised an even split between boys and girls, averaged roughly 16 years of age, and was 59% White and 10% Hispanic/Latino. Using latent class analysis, four subgroups, comprised of varying types and degrees of risky behavior, were identified. Specifically, there were two groups that “abstained” and “experimented” with risky behaviors and two others that had higher, but somewhat distinct, patterns of such activities. These groups were then examined in relation to youth characteristics (e.g., mental and physical health, school performance) and socio-environmental factors (e.g., social support, parental monitoring) that may be useful for better understanding “problem behavior syndrome” and development of prevention strategy.     

Interactions Between Rejection Sensitivity and Supportive Relationships in the Prediction of Adolescents’ Internalizing Difficulties

Rejection sensitivity, the tendency to anxiously or angrily expect rejection, is associated with internalizing difficulties during childhood and adolescence. The primary goal of the present study was to examine whether supportive parent–child relationships and friendships moderate associations that link angry and anxious rejection sensitivity to depression and social anxiety during middle adolescence in an ethnically diverse sample of 277 youth (M age = 14.30 years; 46.93% male). Analyses revealed that angry rejection sensitivity was related to depressive symptoms, but only for adolescents reporting low support from parents and friends. Friend support moderated the association between (1) angry rejection sensitivity and social anxiety, and (2) anxious rejection sensitivity and depressive symptoms. For adolescents reporting low support from friends, support from parents was positively related to social anxiety. Findings highlight the importance of considering relationships in studies of rejection sensitivity and adjustment during adolescence.
