Trace Element Analysis of Rough Diamond by LA‐ICP‐MS: A Case of Source Discrimination?*,†

Abstract: Current profiling of rough diamond source is performed using different physical and/or morphological techniques that require strong knowledge and experience in the field. More recently, chemical impurities have been used to discriminate diamond source and with the advance of laser ablation–inductively coupled plasma–mass spectrometry (LA‐ICP‐MS) empirical profiling of rough diamonds is possible to some extent. In this study, we present a LA‐ICP‐MS methodology that we developed for analyzing ultra‐trace element impurities in rough diamond for origin determination (“profiling”). Diamonds from two sources were analyzed by LA‐ICP‐MS and were statistically classified by accepted methods. For the two diamond populations analyzed in this study, binomial logistic regression produced a better overall correct classification than linear discriminant analysis. The results suggest that an anticipated matrix match reference material would improve the robustness of our methodology for forensic applications.     

Thyroid Cartilage Ossification and Multislice Computed Tomography Examination: A Useful Tool for Age Assessment?

Abstract: Many authors have studied the thyroid cartilage ossification process using radiographic features for age estimation of individuals. Their results were various: Sugiyama reported excellent correlation coefficients between ossification rates and civil age, unlike most other authors. We hypothesized that recent advances in imaging techniques would enable more precise evaluation of the ossification of the thyroid cartilage. We retrospectively analyzed the CT scans of 312 French patients using postprocessing software to examine the pattern of thyroid cartilage ossification, calculating the ossified volume of the cartilage on 3D reconstructions. Pearson’s correlation coefficients for volume were 0.73 for men and 0.75 for women (standard error 18.02 and 17.06), indicating considerable inter‐individual variability. Although a correlation between civil age and morphological changes was found, these methods based on thyroid cartilage ossification were not accurate enough for the assessment of individual age.     

Free amino acid concentrations in vitreous humor and cerebrospinal fluid in relation to the cause of death and postmortem interval

We studied free amino acids in vitreous humor and cerebrospinal fluid from 58 cadavers in the course of routine medicolegal autopsies in the city of Granada. The main objective was to establish whether free amino acids contents in these fluids were related with the cause of death, postmortem interval, and severity of the classic signs of asphyxia. The amino acids (aspartic acid, glutamic acid, serine, glutamine, glycine/threonine/histidine, citruline, arginine, alanine, taurine, GABA, tirosine, valine, methionine, isoleucine, phenylalanine/tryptophan, leucine, and lysine) were quantified by high performance liquid chromatography. There were no statistically significant differences in amino acids concentrations in vitreous humor when the different causes of death were considered. Our results did not show any statistically significant relationship when asphyxial score was plotted against the vitreous content of each amino acid. A statistically significant increase with postmortem interval was observed in vitreous taurine (r = 0.3191, p = 0.01461), glutamate (r = 0.4323, p = 0.0007) and particularly in aspartate (r = 0.4508, p = 0.0003).     

Boundary-spanning strategies for aligning institutional logics: a typology

This article critically examines strategies used by boundary spanners to align the institutional logics of bureaucracy, management and networks in citizen-state interactions. In-depth interviews conducted within the Dutch municipality of Rotterdam reveal that boundary spanners use entrepreneurial, mediation, and hierarchical strategies to align institutional logics. By providing insight into the strategic toolbox of boundary spanners and the perceived effectiveness of these tools, this article enhances empirical understanding of how the interplay between older and newer institutional logics within public organisations takes shape and how boundary spanners make strategic use of hierarchy to overcome institutional barriers.     

Party competition in the Middle East: spatial competition in the post-Arab Spring era

This paper charts the nature of political cleavage between major parties in post-Arab Spring elections in five Mediterranean region countries, with data from online opt-in surveys. We compare the Moroccan elections, held under a consolidated authoritarian regime, with the transitional cases of Tunisia and Egypt as well as the more mature democracies of Turkey and Israel. Voter opinions are obtained on 30 salient issues, and parties and voters are aligned along two dimensions. We trace country-specific cleavage patterns and reflections of party system maturity in these five countries. The cases of Egypt, Tunisia and Morocco reveal that in less settled cleavage structures there is little congruence between vote propensities for parties and agreement levels with policy positions compared to the more institutionalized democracies of Israel and Turkey where voters exhibit a higher likelihood to vote for a party as the distance between the voter and the party in the policy space gets smaller.     

The Contribution of Open Government to Prosperity of Society

The study finds that open government does not only have effect on economic prosperity, but on social capital and environment through the mechanisms of Rule of Law and Control of Corruption. The role of Rule of Law and Control of Corruption are emphasized in this study, because of their significance in mediating open government and prosperity. Unless mechanisms like regulation formulation, law enforcement and control of corruption are not put into practice; open government itself will not be a driving force to a prosperous society.     

Putting Food Sovereignty to Work: Civil Society Governmentalities and Canada’s People’s Food Policy Project (2008–2011)

The People’s Food Policy Project (PFPP) used ‘food sovereignty’ to unite civil society organizations and build a national food policy agenda in Canada from 2008 to 2011. Agri-food scholarship largely highlights the resistance and empowerment dynamic of food sovereignty in the context of neoliberal capital relations. We propose that the story of what food sovereignty discourse does, or could do, in the work of civil society organizations (CSOs), is more complicated. This article contributes to agri-food literature and CSOs studies by examining the governmentalities of the PFPP. We find that the PFPP’s food sovereignty produced at least two discourses: food sovereignty as ethic, or a governmentality of resistance and agrarian empowerment; and food sovereignty as tactic, which we see as a governmentality of administration by CSOs. While PFPP activists increasingly share a spoken commitment to food sovereignty, the analytic of governmentality allows us to show these important differences in the movement, rooted in how CSO actors understand their day-to-day work, and the tensions these differences bring to their seemingly united agenda.     

Introduction: Authority Building in International Administered Territories

This introduction to the special section on “Authority Building in International Administered Territories” begins by summarizing the relevant literature on international administrations. To conceptualize authority building as an ongoing process in which international and local actors confirm – or refuse – authority claims, secondly, two types of authority are differentiated: ‘interpretative authority’ and ‘performing authority’. This sociological conceptualization of authority building allows, thirdly, a discussion on the restrictions and challenges that international administrations face in their attempts to establish authority on the ground. Finally, an overview of the section’s articles is provided.     

“The River Told Me”: Rethinking Intersectionality from the World of Berta Cáceres

ABSTRACT

Inspired by the spiritual and political journey of Berta Cáceres (1973-2016), a fierce Lenca woman leader from Honduras who died in defense of sacred indigenous rivers, the essay aims to rethink the frame of intersectionality that is axiomatic in feminist theorizing and activism. Against the backdrop of the January 2017 Women’s March in the USA, I interrogate inclusionary accounts that equate intersectionality with a pre-existing unity among women that leaves power differentials intact. I recover the intersection as an index of invisibility and violence by drawing on the intimate connections that Berta foregrounded between multiple structures of domination. However, I argue that attending to the relational histories and geographies of patriarchy, colonialism and capitalism, is insufficient for imagining more just futures that are hospitable to subaltern horizons. Feminist praxis must also interrogate the Western liberal conceptions of agency and human-nature relations that undergird its intersectional analysis. Through an exploration of the indigenous cosmovisions and transnational grassroots solidarity that coalesce under Berta’s name, I point to the importance of cultivating a disposition to listening to incommensurable worlds where rivers tell stories and call upon us. This is an ecofeminist vision capable of rooting intersectional analysis within decolonizing relations and alternatives.
