Chemical Imaging of Human Fingermark by X-ray Photoelectron Spectroscopy (XPS)

X-ray photoelectron spectroscopy (XPS) is a widely used technique to characterize the surface chemistry of materials. It plays a crucial role in accessing qualitative and quantitative information and in detecting the presence of chemical functional groups on the surface of any material. The forensic methods available to detect and identify elements and organic/inorganic compounds are often destructive, so evidence cannot be re-analyzed. However, XPS allows rapid analysis of samples without damaging them. Recently, an increasing number of forensic researchers have begun to study certain chemical information on fingermarks. In this study, the authors aimed to present the applicability and power of XPS imaging in fingermark analysis which can also provide specific information about the fingermark chemical composition. Herein, monochromated X-ray (Al Kα) spot size was fixed at 50 μm. XPS mapping resulted in the acquisition of spectra at each pixel, in an array of 41 × 30 pixels with a step size of 50 μm. Then, a simple discussion has been made about how the scanned surface spectrum and basic snapshot spectra are used to identify different components at a fingertip of a scanned surface area (~3 mm²). Hence, a fingermark pattern contaminated with caffeine, TiO₂, and Pb/PbO deposited on the silicon wafer can be chemically mapped and visualized by XPS using principal component analysis (PCA). Thus, the present study showed the possible applicability of XPS for the identification of illicit drugs of abuse, gunshot residue, and skin care products on latent fingermark by mimicking a crime scene evidence.     

Laughter and Liability: The Politics of British and Dutch Television Satire

Contemporary politicians face immense rhetorical and communicative challenges. Performing on the intertwined stages of politics, media (including Internet) and everyday life, they need to master diverse and contrasting repertoires of talk. Political communication research, at present, has ignored the question of how politicians face and experience these challenges, and how they reflect on the new communicative field. In this article, we begin to redress this situation by analysing and comparing the motives, experiences and reflections of politicians who appeared in the British satirical TV show, Have I Got News for You, and its Dutch adaptation, Dit was het Nieuws. Based on in-depth interviews with seven Dutch and 14 English MPs, we conclude that they draw from three repertoires to legitimise and reflect on their participation: a strategic, indulgent and anti-elitist repertoire. The first repertoire is predictable in the context of current political communication research, whereas the latter two add new dimensions of pleasure and bottom-up representation to it.     

Living and Teaching Across Cultures

As long as one lives within the confines of a single culture it is difficult to achieve cross-cultural awareness. Multiculturalism is often simply the tolerance of a dominant culture for minority cultures. Cross-cultural awareness is a state of mind in which one is alert to alternity , the existence of others possessing different and equally valid world views and ways of life. This can be acquired living within or alongside other cultures, when one's own and others' strangeness become readily apparent. Culture shock involves just such a realization. The challenge for the teacher of international relations is to convey the possibility of alternity to students in the classroom. After all, international relations is above all about the interaction between communities possessing separate identities and autonomous wills. The article discusses ways of cultivating cross-cultural awareness, comparing the difficulties of doing so in a society under siege—Israel—with the greater scope available in the cosmopolitan setting of an elite American university.     

Intra-Campaign Changes in Voting Preferences: The Impact of Media and Party Communication

An increasing number of citizens change and adapt their party preferences during the electoral campaign. We analyze which short-term factors explain intra-campaign changes in voting preferences, focusing on the visibility and tone of news media reporting and party canvassing. Our analyses rely on an integrative data approach, linking data from media content analysis to public opinion data. This enables us to investigate the relative impact of news media reporting as well as party communication. Inherently, we overcome previously identified methodological problems in the study of communication effects on voting behavior. Our findings reveal that campaigns matter: Especially interpersonal party canvassing increases voters’ likelihood to change their voting preferences in favor of the respective party, whereas media effects are limited to quality news outlets and depend on individual voters’ party ambivalence.     

Evolving 'Discoarse' into Discourse: Ubuntu as a Normative Basis

Democratic discourses are increasingly devolving into mudslinging matches where communicators attack their opponents—sometimes in crude and hostile ways. Underlying this type of discourse is the normative assumption that human affairs are inherently conflicting and best governed through struggles and contests. When considering why some discourses warrant re-examination and how this can be achieved, the role of culture and ethics becomes apparent. While our prevalent culture of adversarialism unearths many important facets of discussion, its discourses can also obscure valuable insights and foster division where collaboration is possible and quite possibly desirable. As such, contrasting normative approaches are worth considering. The African philosophy of ubuntu offers such an alternative as it espouses a harmonious and cohesive way of relating to fellow human beings that contrasts and complements individualist facets. It provides the space to evolve discourses in ways that support cooperative societal structures and practices.     

From clouds of chemical warfare to blue skies of peace: the Tehran Peace Museum,Iran

Despite the limited number of peace museums around the world, there exists an essential role for existing peace museums to promote a culture of peace and peace education. The purpose of this article was to introduce the origins, rationale, scope and work of the Tehran Peace Museum in Iran. The concept of the museum is to facilitate peace education and develop peaceful environments drawn from the personal experiences of war survivors. The museum encompasses exhibitions about the horrors of chemical and nuclear warfare and is balanced with awareness programmes, bridge-building dialogues, connections with other peace museums and a comprehensive peace education programme catering for younger and older members of society. It offers the space and opportunity for a community of learning within the museum and welcomes fresh ideas and initiatives from visitors and volunteers. The Tehran Peace Museum is unique in its body of volunteers, men and women who have been directly affected by chemical weapons. They are involved in the Veterans Voices of Peace Oral History Project and actively voice the need for creating peaceful societies in today’s world.     

The Effects of Blaming Others for Legislative Inaction on Individual and Collective Evaluations

Legislators commonly blame others for gridlock. We posit that legislators may engage in this type of rhetoric to minimize the individual reputational risks associated with legislative inaction or to boost the relative standing of their party. In a series of six survey experiments, we find that blaming others for inaction undermines voters’ evaluations of individual legislators who engage in this rhetorical strategy. This effect is particularly pronounced among out-partisans and independents. However, blaming rhetoric can also enhance the standing of the blamer’s party relative to the opposing party across all groups (including out-partisans), in large part by undermining the reputations of these other actors. Ultimately, we show that when an individual legislator engages in blaming rhetoric, the immediate net electoral effects are null. This suggests that coordinated efforts by a party to blame opponents may improve the party’s relative standing, while imposing few costs on those engaged in blaming.

Communication uncertainty and the fictional role of organizational culture

This theoretical investigation aims to critically analyze the concept of organizational culture as an example of ＂organizational fiction＂. In order to benefit from unveiling organizational fictions, it is necessary to be aware of how illusion is linked to stability and predictability. It is here proposed to consider communicational uncertainties as positive qualities in flexible organizations, where communicative flows between organizational spheres and individual spaces of employees or managers engender new ideas and foster creativity. Thus, a strong organizational culture, especially in intercultural contexts, may be a barrier to organizational health, but a strong and unified corporate identity is necessary to guarantee organizational stability and cohesion. The solution is the interplay between stability and contingent openness toward external influences.
