Variation of δ2H, δ18O & δ13C in crude palm oil from different regions in Malaysia: Potential of stable isotope signatures as a key traceability parameter

A total of 33 crude palm oil samples were randomly collected from different regions in Malaysia. Stable carbon isotopic composition (δ¹³C) was determined using Flash 2000 elemental analyzer while hydrogen and oxygen isotopic compositions (δ²H and δ¹⁸O) were analyzed by Thermo Finnigan TC/EA, wherein both instruments were coupled to an isotope ratio mass spectrometer. The bulk δ²H, δ¹⁸O and δ¹³C of the samples were analyzed by Hierarchical Cluster Analysis (HCA), Principal Component Analysis (PCA) and Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA). Unsupervised HCA and PCA methods have demonstrated that crude palm oil samples were grouped into clusters according to respective state. A predictive model was constructed by supervised OPLS-DA with good predictive power of 52.60%. Robustness of the predictive model was validated with overall accuracy of 71.43%. Blind test samples were correctly assigned to their respective cluster except for samples from southern region. δ¹⁸O was proposed as the promising discriminatory marker for discerning crude palm oil samples obtained from different regions. Stable isotopes profile was proven to be useful for origin traceability of crude palm oil samples at a narrower geographical area, i.e. based on regions in Malaysia. Predictive power and accuracy of the predictive model was expected to improve with the increase in sample size. Conclusively, the results in this study has fulfilled the main objective of this work where the simple approach of combining stable isotope analysis with chemometrics can be used to discriminate crude palm oil samples obtained from different regions in Malaysia. Overall, this study shows the feasibility of this approach to be used as a traceability assessment of crude palm oils.     

Communicating sociocultural norms and social and religious practices in Iranian death notices

Drawing on a corpus of 100 randomly collected death notices published in an Iranian national newspaper, this study examined generic structures as well as their lexico-grammatical patterning to reveal what communicative functions are articulated by these generic components. Basing our identification of moves on Swales [1990. Genre Analysis: English in Academic and Research Settings. Cambridge: Cambridge University Press], we identified 12 rhetorical moves in the corpus. We illustrated that these recurrent rhetorical moves reflect the Iranian sociocultural norms, as well as social and religious beliefs. Also, the results substantiated [Kress, Gunther, and Theo van Leeuwen. 1996. Reading Images: The Grammar of Visual Design. London: Routledge] multimodality perspective on textual analysis in that they rejected linguistic items as the only meaning-making device and identified colour, position, photo and size, among others, as worthwhile veritable semiotic devices.     

THE POLITICAL SYSTEM IN IRAQI KURDISTAN: PARTY RIVALRIES AND FUTURE PERSPECTIVES

The Kurdistan Region of Iraq (KRI) possesses many of the traditional hallmarks of political authority and society, such as state institutions (an Executive, Legislature, and Judiciary), political parties, civil society, elections, and local government. Nevertheless, for the past twenty-five years, it has failed to create a unified political system that adheres to a mutually accepted form of government. Political division, in particular, a rivalry between the main parties, has proved to be a real impediment to the political development and stability of the Region.

This article argues that there is a relationship between the nature and structure of the political parties, which reflects interests' political views of party leaders, and the political systems that have been proposed as solutions to a lack of political stability in Iraqi Kurdistan. Specifically, it argues that the individual character of the main parties, the PUK and the KDP above all, explains why they favour one system of government over the one advanced by their rival and is the core political dispute in Iraqi Kurdistan currently. Finally, the article concludes by identifying prospective systems of government available the KRI and the potential consequences of each.

International criminal justice: reflections on the past and the future

While Nuremberg constitutes a watershed in the evolution of international law with its establishment of the fundamental principle of individual criminal responsibility under international law it has not left much else by way of precedent for the subsequent international criminal tribunals. The adoption of UN Security Council Resolution 827 establishing the International Criminal Tribunal for the Former Yugoslavia, and Resolution 955 (1994) establishing the International Criminal Tribunal for Rwanda, set the groundwork for a new model of hybrid tribunals, with the establishment of the Special Court for Sierra Leone in 2002, the Extraordinary Chambers in the Courts of Cambodia in 2006, and the Special Tribunal for Lebanon in 2007. Perhaps one of the greatest legacies of these ad hoc and hybrid courts and tribunals has been paving the way for the establishment of a permanent international criminal court. However, they have also brought about the development of international criminal law through judicial interpretation, elaborating, inter alia, the elements of the crime of genocide as detailed in the 1948 Genocide Convention, the judicial recognition of the concept of joint criminal enterprise and the principle that national arrangements for amnesties in respect of international crimes are no bar to prosecution for such crimes at an international tribunal. In view of the completion strategies of the ad hoc Tribunals, as well as of the SCSL, this article delves into some of their legacies and outlines some of the difficulties and challenges they have faced, while identifying areas of best practice in order for the newly‐operational International Criminal Court to avoid repeating the mistakes of the past or even reinventing new wheels.     

The Future of Chemical Weapons: Implications from the Syrian Civil War

Abstract

With chemical weapons (CW) use in Syria raising questions about the health of the CW norm, this article analyzes whether the Syrian case will lead to further proliferation and use of chemical weapons by states. We examine the use of chemical weapons at Ghouta in 2013 and on the Hama Plains in 2014 and find that: first, chemical weapons have demonstrated limited military utility in Syria, either tactically or as a tool of civilian victimization; second, the costs of use have been repeatedly demonstrated by the international reaction to their use; and third, the use of sarin—a nerve agent—has attracted a stronger international response than the use of chlorine, a less lethal agent. Consequently, we conclude that the Syrian case is unlikely to lead to significant proliferation and use of chemical weapons; any that does occur is most likely to involve states already outside the CW norm.     

Incidental findings in CT colonography: literature review and survey of current research practice

Incidental findings (IFs) of potential medical significance are seen in approximately 5-8 percent of asymptomatic subjects and 16 percent of symptomatic subjects participating in large computed tomography (CT) colonography (CTC) studies, with the incidence varying further by CT acquisition technique. While most CTC research programs have a well-defined plan to detect and disclose IFs, such plans are largely communicated only verbally. Written consent documents should also inform subjects of how IFs of potential medical significance will be detected and reported in CTC research studies.
