Understanding food security and international security links in the context of climate change

Food production has been changing significantly in recent years as a result of climate change and of growing demand for food. This article aims to understand the link between food security and international security in the context of climate change, applying a systematic and qualitative analysis of the literature using the bibliometric method. This research observes that climate change tends to affect agricultural productivity, exposing societies to risk and the need for migration. However, good governance, together with international cooperation, can reduce the hazards of food insecurity, strengthening ties between countries and stimulating a fairer and more inclusive form of international trade.     

Shifting linkages in ethnic mobilization: the case of RMDSZ and the Hungarians in Transylvania

The Democratic Alliance of Hungarians in Romania (RMDSZ) has been the most stable actor in the Romanian party system over the past two decades. However, in this article, we argue that beyond this apparent stability, the linkages between RMDSZ and its voters have undergone a gradual, yet significant shift. The ethnic block voting of Transylvanian Hungarians was closely connected to the concept of a self-standing and parallel “Minority Society,” and to the practices of institution building that the minority elites engaged in in the early 1990s. However, since its first participation in the Romanian government in 1996, RMDSZ has gradually departed from this strategy, a phenomenon that was also closely connected to a process of elite change within the organization. The present RMDSZ leadership puts less and less emphasis on policy programs that could reinforce the institutional system of the minority; consequently, it is unable (and unwilling) to organizationally integrate the community activists of the minority society who previously had played a key role in the process of (electoral) mobilization. At the rhetorical level, RMDSZ did not abandon the goal of building a parallel Hungarian minority society, but in its linkages to the Hungarian electorate, clientelistic exchanges have become predominant.     

From Communal Patriotism To City-State Chauvinism: Transformation of Collective Identities in Northern Italy, 1050–1500

At the turn of the first millennium, the rise of autonomous communes and city-states in northern Italy coincided with the development of a particular sense of attachment to land and city, which is widely labeled as civic patriotism. Neither the transformation of these collective identities across time nor the macrostructural dynamics behind this transformation has received much attention. Through an examination of these communes and city-states from the eleventh to the sixteenth century, this paper unpacks different forms of collective identities that prevailed in northern Italy in different periods of time, all of which have previously been labeled as “patriotism” in the literature. The differentiation I propose between “communal patriotism,” “civic nationalism,” and “city-state chauvinism” presents a more nuanced picture which highlights the differences in the ways these collective identities are produced, reproduced, and transformed. My analysis also discusses the role played by macrostructural dynamics (e.g., changing climate in the macropolitical economy as well as inter-city-state system in the peninsula) in transforming these collective identities. Alongside a longue durée evolutionary transformation, there were two conjunctural moments which created ruptures in the transformation of collective identities in northern Italy: The first took place during the territorialization of the communes and the conquest of the contado in the mid-twelfth century and the second occurred in the aftermath of the crisis of the fourteenth century.     

Fair Trade and justice: a comment on Walton and Deneulin

In this article we first point out that the different conceptualisations of Fair Trade, which are sometimes analytically contradictory, actually form a coordinated set. Understanding the Fair Trade project is impossible without taking these interlinked conceptualisations into consideration. Second, this set basically forms a mechanism of structural, institutional and moral reforms that guide actions. In this way Fair Trade sets out to produce less injustice than is usually the case with the structures and institutions that govern conventional trade. Nevertheless, it does not try to define what a just society is or even to perfectly define ‘fair trade’. This implies the adoption of a comparative justice angle. It is precisely by linking comparative individual situations with the structures that produce these situations that relative justice can find its strength and purpose.     

Rural unions and the struggle for land in Brazil

Studies of Brazil's agricultural labor movement have generally neglected its relationship to the struggle for land, but this is neither fair nor accurate. Analyzing the rural labor movement's historical contributions to the land struggle in Brazil, this contribution has been organized into three main periods, emphasizing social relations, institutional activism and policy changes. It argues that despite the peculiarities of different historical contexts, rural labor consistently provoked protest against policies that privileged large landholders, whose concentration of power over land and labor resources continually worsened Brazil's ranking as one of the most unequal of nations. For more than half a century, the most constant opponent of this situation among the peasantry has been the National Confederation of Workers in Agriculture (CONTAG), a corporatist organization of rural labor unions founded in 1963.     

Searching for Autonomy before the Transition to Higher Education: How do Identity and Self-Determined Academic Motivation Co-Evolve?

Identity and academic motivation are particularly at stake before the major transition to higher education. However, few studies have explored their changes and their longitudinal bidirectional links. To fill this gap, a three-wave study from the end of the 11th grade to the end of the 12th grade was conducted to explore changes in identity processes and academic motivation and to investigate how they might be interconnected over time. 599 adolescents (mean age 17.4; 59% girls) completed questionnaires containing measures about identity processes and three types of academic motivation: autonomous, controlled, and impersonal. Throughout the study span of one year, four identity processes increased: commitment making, identification with commitment, exploration in breadth and exploration in depth, while the process of ruminative exploration decreased. Simultaneously, late adolescents encountered an increase in impersonal motivation, more salient for boys. The results also revealed unidirectional links from motivation to identity processes, with no gender or age moderator effects: exploration in breadth and exploration in depth were positively predicted by autonomous motivation, ruminative exploration was positively predicted by autonomous, controlled, and impersonal motivation. In addition, impersonal motivation negatively predicted commitment making. On the other hand, identification with commitment positively predicted autonomous motivation. Practical implications are discussed.

     

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.     

Volatile Organic Compounds,Spectral Characterization and Morphology of Ammonium Nitrate Fuel Oil (ANFO) Samples

Ammonium nitrate fuel oil is an explosive mixture found in most antipersonnel landmines (APL) buried throughout the Colombian territory. During more than 50 years of internal conflict, the Colombian government has found that trained dogs are the most effective method to detect APL. However, the olfactive signature in ANFO is unknown and also if there are differences in detection related to the explosive manufacturing origin. Therefore, this work begins with the analytical validation of the method used to determine ammonia, in its derivatized form as carbamate, released by home-made ANFO using HS-SPME-GC-FID. Once validated, the method was used to identify ammonia and other organic volatile compounds present in ANFO, under laboratory and simulated field conditions. The validation process includes the evaluation of the optimum conditions for the derivation and extraction of butylcarbamate, the determination of the working ranges with linear response in FID, the limits of detection and quantification, the sensitivity, and the precision. The results of the validation established linearity and sensitivity in a concentration between 20 and 120 mg/L, as well as low limits of detection and quantification of 6.4 and 21.4 mg/L, respectively. Also, an intermediate precision of 11% for butylcarbamate with a repeatability of 8%. The validated method showed in real samples of home-made ANFO besides ammonia, the presence of low molecular methylamines, and also exhibited differences in volatile compositions according to the origin. The objective of this work is to offer a reliable analytical methodology for the extraction and analysis of volatile compounds from ANFO.     

Combined Collection and Analysis of Inorganic and Organic Gunshot Residues

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid^® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method.
