Portuguese ecotypes of Opuntia ficus-indica differ in biomass production

The Opuntia ficus-indica (L.) Miller is a species from the Cactaceae family with the center of origin and domestication in central Mexico. This species introduction in the Iberia Peninsula occurred, probably, by the end of the 15th century, after the discovery of America, spreading later throughout the Mediterranean basin. In Portugal, O. ficus-indica is located, usually, with a typical ruderal behavior, at the edge of roads and paths. In Portugal, as in other Mediterranean regions, inlands areas are under severe draught during extensive summers, in particular, and global warming is expected to affect them deeply in the near future. O. ficus-indica, by its morpho-physiological characteristics and multiple economic uses, represent an alternative crop for those regions. Sixteen Portuguese O. ficus indica ecotypes and two ‘Italian’ cultivars ("Gialla" and "Bianca") were evaluated for plant vigor and biomass production, by nondestructive methods, in the two years following planting. Biomass production and plant vigor were measured by estimating cladode number, cladode area and fresh weight per plant. Linear models to predict the area of cladodes and fresh weight per plant were previously established using a biometric analysis of 180 cladodes. It was not possible to establish an accurate linear model for dry matter using non-destructive estimation. Significant differences were found among populations in the studied biomass-related parameters, and different groups were unfolded. A group of four Portuguese ecotypes outperformed in terms of biomass production, comparable with the “Gialla” cultivar. This group could be used to start a breeding program with the objective of deploy material for animal feeding, biomass and fruit production. Nevertheless, the ‘Gialla’ cultivar showed the best performance, achieving the highest biomass related parameters, not surprisingly for it is an improved plant material.

Latin Sources of Inspiration for 15th and 16th Century Orthodox Prints

The project studied the history of Orthodox graphic art in the context of artistic links between the Eastern and Western worlds, tracing the routes by which iconographic models from western Europe penetrated into eastern Europe and underscoring the role of central European countries in the shaping of the culture of the modern Orthodox church. One important element was the identification of graphic prototypes and export routes for woodcutting blocks which travelled from Germany via Prague, Cracow and Vilnius to Moscow and Kiev, revealing the artistic ties between followers of different religions. Another major element was a study of the appearance of copper engraving in the second half of the 17th century.

Managing distraction in 21st century learning environments

First year students attend face-to-face classes armed with an arsenal of internet enabled digital devices. The conundrum is that while these devices offer scope for enhancing opportunities for engagement in face-to-face learning, they may simultaneously distract students away from learning and compound isolation issues. This paper considers how to best to use these devices for maximum engagement in first year face-to-face learning so as to assist students in connecting with other learners and instructors within the learning environment

Literature in Bosnia and Hercegovina till 19th Century in South Slav Context

Mr. Gajevic traced the development of literacy and literature in Bosnia and Herzegovina from the 12th to the 19th in relation to other south Slavic literatures and civilisations, studying their interrelations, links and influences. From the 12th to the 15th centuries, literature in this area developed under strong influence from the neighbouring South Slavic countries, which were directly connected with more developed foreign cultures and civilisations. The literatures of these countries had differing religious and cultural backgrounds, some developing under Byzantine and Orthodox influence and others as a part of Latin civilisation and the Catholic religion. This led to different and sometimes contradictory literary, religious and other influences on Bosnia and Herzegovina, making spiritual and religious unity for the country virtually impossible. Under the influence of the Bosnian state and church, however, there were signs of a search for compromise, leading to some mixing of the difference traditions. Following the Turkish conquest, however, three denominational communities (Orthodox, Catholic and Muslim) developed in Bosnia and Herzegovina and this became the general framework for life, including literature. This led to three separate literary traditions - Serb-Orthodox, Croat-Catholic and Bosniac-Islamic. This internal disintegration of Bosnian literature did however facilitate the process of integration of some of its denominational traditions with similar traditions in other countries. The third aspect considered in the research was the genesis and expansion of vernacular and folk literature from Bosnia and Herzegovina throughout the South Slavic areas and its contribution to the language and literature integration of four peoples - Serbs, Croats, Bosniacs and Montenegrins. Of special interest here were the aspirations of the Catholic church to establish the Bosnian language as the common South Slavic literary language for its religious and propaganda activities, and the contribution of Vuk Stefanovic Karadzic to the effort to establish the "Bosnian language" as the common literary language of the South Slavic peoples.

Lady Nugent and Tom Cringle on the veranda : early nineteenth century observations on a Caribbean architectural feature

This study of the veranda as seen through the eyes of Lady Maria Nugent and Michael Scott, alias Tom Cringle, clearly demonstrates the important role that the piazza, as it was then more commonly known, played in the life of early nineteenth century Caribbean colonial society. The popularity of the veranda throughout the region, in places influenced by different European as well as African cultures, and among all classes of people, suggests that the appeal of this typical feature was based on something more than architectural fashion. A place of relative comfort in hot weather, the veranda is also a space at the interface of indoors and outdoors which allows for a wide variety of uses, for solitary or small or large group activities, many of which were noted by Nugent and Scott. Quintessentially, the veranda is a place in which to relax and take pleasure, not least of which is the enjoyment of the prospect, be it a panoramic view, a peaceful garden or a lively street scene. Despite the great changes in the nature of society, in the Caribbean and in many other parts of the world, the veranda and related structures such as the balcony continue to play at least as important a role in daily life as they did two centuries ago. The veranda of today’s Californian or Australian bungalow, and the balcony of the apartment block in the residential area of the modern city are among the contemporary equivalents of the lower and upper piazzas of Lady Nugent’s and Tom Cringle’s day.

Can IT Security be improved with better IT Leadership in the 21st Century University?

Organizations generally are not responding effectively to rising IT security threats because people issues receive inadequate attention. The stark example of IT security is just the latest strategic IT priority demonstrating deficient IT leadership attention to the social dimension of IT. Universities in particular, with their devolved people organization, diverse adoption of IT, and split central/local federated approach to governance and leadership of IT, demand higher levels of interpersonal sophistication and strategic engagement from their IT leaders. An idealized model for IT leaders for the 21st century university is proposed to be developed as a framework for further investigation. The testing of this model in an action research study is proposed.
