Big cat scan: magnetic resonance imaging of the tiger

In August 2002, we performed MRI scans on a female juvenile Bengal tiger. We present the clinical course, imaging and autopsy findings, and some comparative anatomy of the tiger brain and skull. Magnetic resonance images of a tiger have not previously been published.

Tiger, tiger, burning bright? Industrial policy “lessons” from Ireland for small African economies

The chapter examines possibilities for industrial policy in African countries through the lens of lessons that can be learned from the industrial policy approaches pursued in Ireland as well as in East Asia. As latecomers to industrialization, the small African economies are well positioned to undertake such an exercise, we suggest. This chapter provides some novel insights by providing a comparison between Ireland and the small African economies. To our knowledge such a comparison offers a unique contribution. Cognizant of the fact that a “one size fits all” approach to industrial policy is not appropriate in the African context, we argue in favor of the adoption of a more “holistic” approach to industrial policy in these economies. Such an approach we argue should focus simultaneously on demand and supply factors of industrial development, and on microeconomic as well as macroeconomic factors.

Seasonality and geographical occurrence of West Nile fever and distribution of Asian tiger mosquito

The importance and risk of emerging mosquito borne diseases is going to increase in the European temperate areas due to climate change. The present and upcoming climates of Transdanubia seem to be suitable for the main vector of Chikungunya virus, the Asian tiger mosquito, Aedes albopictus Skuse (syn. Stegomyia albopicta). West Nile fever is recently endemic in Hungary. We used climate envelope modeling to predict the recent and future potential distribution/occurrence areas of the vector and the disease. We found that climate can be sufficient to explain the recently observed area of A. albopictus, while in the case of West Nile fever, the migration routes of reservoir birds, the run of the floodplains, and the position of lakes are also important determinants of the observed occurrence.

Size-based variation in intertissue comparisons of stable carbon and nitrogen isotopic signatures of bull sharks (Carcharhinus leucas) and tiger sharks (Galeocerdo cuvier)

Stable isotopes are important tools for understanding the trophic roles of elasmobranchs. However, whether different tissues provide consistent stable isotope values within an individual are largely unknown. To address this, the relationships among carbon and nitrogen isotope values were quantified for blood, muscle, and fin from juvenile bull sharks (Carcharhinus leucas) and blood and fin from large tiger sharks (Galeocerdo cuvier) collected in two different ecosystems. We also investigated the relationship between shark size and the magnitude of differences in isotopic values between tissues. Isotope values were significantly positively correlated for all paired tissue comparisons, but R2 values were much higher for δ13C than for δ15N. Paired differences between isotopic values of tissues were relatively small but varied significantly with shark total length, suggesting that shark size can be an important factor influencing the magnitude of differences in isotope values of different tissues. For studies of juvenile sharks, care should be taken in using slow turnover tissues like muscle and fin, because they may retain a maternal signature for an extended time. Although correlations were relatively strong, results suggest that correction factors should be generated for the desired study species and may only allow coarse-scale comparisons between studies using different tissue types.

Tittmann and the 'Tiger Car' : competing conceptions of modernity in Haiti, 1946-50

The purpose of this project was to address the lack of scholarship on mid-twentieth century Haitian history and illustrate its significance. It employs primary and secondary sources in shaping a Gramscian historical narrative. Ideas of "everyday resistance" and internal and external politics are also be of significance to this work. In mid-twentieth century Haiti, the black-nationalist rhetoric of noirisme became the dominant political ideology. Blackness was amorphous and its application to politics was dependent upon class. In proclaiming blackness the average Haitian was attacking the class schism that beleaguered the island. Yet for the elite noirismewas a conduit to modernity and a useful tool for muting the division between rich and poor. With the election of Dumarsais Estimé in 1946, dialogue between the U.S. government, the Haitian elite, and the masses, relative to definitions of modernity played out within the new political reality of noirisme.

Rising temperatures increased recruitment of brown tiger prawn (Penaeus esculentus) in Moreton Bay (Australia)

Abiotic factors are fundamental drivers of the dynamics of wild marine fish populations. Identifying and quantifying their influence on species targeted by the fishing industry is difficult and very important for managing fisheries in a changing climate. Using multiple regression, we investigated the influence of both temperature and rainfall on the variability of recruitment of a tropical species, the brown tiger prawn (Penaeus esculentus), in Moreton Bay which is located near the southern limit of its distribution on the east coast of Australia. A step-wise selection between environmental variables identified that variations in recruitment from 1990 to 2014 were best explained by a combination of temperature and spawning stock biomass. Temperature explains 35% of recruitment variability and spawning stock biomass 33%. This analysis suggests that increasing temperatures have increased recruitment of brown tiger prawn in Moreton Bay.
