Sources of nutrition information for persons living in Trinidad and Tobago

Health consumers worldwide obtain nutrition information from various sources; however, the sources Trinidadians and Tobagonians accessed were unclear. This cross-sectional, descriptive study ascertained from which sources Trinidadians and Tobagonians obtained nutrition information. Participants (n = 845) were surveyed with questions regarding demographics and nutrition information sources. Nearly 100% agreed nutrition information was important. Persons 18-64 years old mainly accessed print media (p<0.01) and ≥ 65years old predominantly accessed the non-print media. Significantly more tertiary educated people, ≥ 35 years old, retrieved information from print media (p=0.001), health care professionals (p=0.001), food labels (p=0.006), and non-print media (p=0.03) when compared to those < 35 years with similar education. Tertiary educated people (67%), selected the Internet when compared to those with without tertiary education (33%) (p<0.001). Knowing the nutrition information sources accessed, dietitians will be able to provide consistent, accurate, age specific nutrition information and promote healthy eating among Trinidadians and Tobagonians.

Turkey and Neo-Ottomanism: Domestic Sources, Dynamics and Foreign Policy

This study examined the relationship between the Turkish Islamic movements and the present government of the Justice and Development Party (Adalet ve Kalkinma Partisi, AK Party). Since the AK Party came to power in 2002 it implemented unparalleled political reforms and pursued to improve Turkey’s relations with the EU. Opponents argued that because of the dominance of the secular military in Turkish politics, the AK Party is forced to secretly advance its Islamic agenda using the language and symbolism of democracy and human rights. This study argued that the ideas of the AK Party show similarities with the “Ottomanist” thought of the late Ottoman era. With special reference to the preservation of the Ottoman State, Ottomanism in an eclectic way was able to incorporate Islamic principles like freedom, justice and consultation into the political arena which was increasingly dominated by the secular European concepts. Literature on Islam and politics in Turkey, however, disregards the Ottoman roots of freedom and pluralism and tends to reduce the relationship between religion and state into exclusively confrontational struggles. This conceptualization of the political process relies on particular non-Turkish Muslim experiences which do not necessarily represent Islam’s venture in Turkey. Contrary to the prevailing scholarship, Islamic movements in Turkey, namely, Naqshbandi, National View and Nur, which are discussed in detail in this study, are not monolithic. They all uphold the same creedal tenets of Islam but they have sharp differences in terms of how they conceptualize the role of religious agency in politics. I argue that this diversity is a result of three distinct methodologies of Islamic religious life which are the Tariqah (Tarikat), Shariah (Şeriat), and Haqiqah (Hakikat). The differences between these three approaches represent a typological hierarchy in the formation of the Muslim/believer as an agent of Islamic identity. Through these different if not conflicting modes, the AK Party reconnected itself with Turkey’s Ottoman heritage in a post-Ottoman, secular setting and was able to develop an eclectic political identity of Neo-Ottomanism that is evident in the flexibility if not inconsistency of its domestic and foreign policy preferences.

Sources, Fate and Transformation of Organic Matter in Wetlands and Estuaries

Dissolved organic matter (DOM) is a complex mixture of organic compounds and represents the largest reservoirs of carbon (C) on earth. Particulate organic matter (POM) is another important carbon component in C cycling and controls a variety of biogeochemical processes. Estuaries, as important interfaces between land and ocean, play important roles in retaining and transforming such organic matter (OM) and serve as both sources and sinks of DOM and POM. There is a diverse array of both autochthonous and allochthonous OM sources in wetland/estuarine ecosystems. A comprehensive study on the sources, transformation and fate of OM in such ecosystems is essential in advancing our understanding of C cycling and better constraining the global C budget. In this work, DOM characteristics were investigated in different estuaries. Dissolved organic matter source strengths and dynamics were assessed in a seagrass-dominated subtropical estuarine lagoon. DOM dynamics controlled by hydrology and seagrass primary productivity were confirmed, and the primary source of DOM was quantified using the combination of excitation emission matrix fluorescence with parallel factor analysis (EEM-PARAFAC) and stable C isotope analysis. Seagrass can contribute up to 72% of the DOM in the study area. The spatial and temporal variation of DOM dynamics was also studied in a freshwated dominated estuary fringed with extensive salt marshes. The data showed that DOM was primarily derived from freshwater marshes and controlled by hydrology while salt marsh plants play a significant role in structuring the distribution patterns of DOM quality and quantity. The OM dynamics was also investigated in a mangrove-dominate estuary and a comparative study was conducted between the DOM and POM pools. The results revealed both similarity and dissimilarity in DOM and POM composition. The dynamics of both OM pools are largely uncoupled as a result of source differences. Fringe mangrove swamps are suggested to export similar amounts of DOM and POM and should be considered as an important source in coastal C budgets. Lastly, chemical characterizations were conducted on the featured fluorescence component in OM in an attempt to better understand the composition and origins of the specific PARAFAC component. The traditionally defined ‘protein-like’ fluorescence was found to contain both proteinaceous and phenolic compounds, suggesting that the application of this parameter as a proxy for amino acid content and bioavailability may be limited.
