Tuberose (Polianthes tuberosa L.) is a perennial summer flower grown by smallholders in Kenya for export. However, its production and export volumes have declined drastically due to nematodes infestation. This study evaluated the effect of Cleome gynandra accessions on nematode management on tuberose. Experiment was conducted at the Horticulture Research Field, Egerton University, Kenya using a randomized complete block design with four replications. The treatments were: five accessions of C. gynandra namely ‘Simlaw’, ‘Egerton’, ‘Taastrup’, ‘PS’ and ‘IP8’, applied at 6 kg/m2 and compared with Brassica napus, solarization and untreated control. Data was collected on growth and yield parameters, nematode infestation and quality of tuberose. Data collected was subjected to analysis of variance at p≤0.05 and means separated using Tukey’s test. Biofumigation with Cleome gynandra accessions helped to reduce nematode population by 34%, gall numbers by 83% and galling index by be 96% when compared with the control. Use of biofumigation helped to improve plant height and leaf number of tuberose by 16% and 87%, respectively, when compared with the control. Use of biofumigation helped to improve spike length by 32%, marketable spikes by 80%, and flower yield by 90% and reduced nonmarketable spikes by 95% when compared with the control. Based on the above results, use of Cleome gynandra accessions and other biofumigants such as rape seed can be used to manage nematodes and improve growth, yield and quality of tuberose.

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

Abstract Ruth Finnegan FBA OBE (1933, Derry, Northern Ireland) took a DPhil in Anthropology at Oxford, then joined the Open University of which she is now an Emeritus Professor. Her publications include Oral Literature in Africa (1970), Oral Poetry (1977), The Hidden Musicians: Music-Making in an English Town (1989), and Why Do We Quote? The Culture and History of Quotation (2011). Ruth Finnegan was interviewed by Sarali Gintsburg (ICS, University of Navarra) and Luis Galván Moreno (University of Navarra) on the occasion of an online lecture delivered at the Institute for Culture and Society at the University of Navarra. In this trialogue-like interview, Ruth tells about the childhood experiences that were decisive for her interest in orality and storytelling, about her education and training as a Classicist in Oxford, the beginnings of her fieldwork in Africa among the Limba of Sierra Leone, and her recent activity as a novelist. She stresses the importance of voice, of its physical, bodily dimensions, its pitch and cadence; and then affirms the essential role of audience in communication. The discussion then touches upon several features of African languages, classical Arabic and Greek, and authoritative texts of Western culture, from Homer and the Bible to the 19th century novel. Through discussing her childhood memories, her assessment of the development and challenges of anthropology, and her views on the digital transformation of the world, Ruth concludes that the notion of narrative, communication, and multimodality are inseparably linked.

AbstractThe essay highlights the role of one individual, Nawab Siddiq Hasan Khan (1832-90), in writing the cultural and intellectual history of imperialisms. It brings his biography, journeys and intellectual forays together to show how he used the temporal moment of the mid 19th century ‘age of revolts’, and the spatial connectivity offered by British and Ottoman imperialisms and re-configured them to his own particular interests. Locating Siddiq Hasan in the connected histories of the British and Ottoman Empires, it views his in-house cosmopolitanism as a form of public conduct that was shaped by Islamic learning that cultivated urbane civility as Muslim universalist virtuous conduct. This was a form of cosmopolitanism enabled by imperial networks, informed by pre-colonial webs of interaction between India and West Asia, and deeply rooted in the scriptures.

The influence of religion and spirituality (R/S) on surgeons dates back to the early history of modern surgery and continues into the 21st century. Research topics include intercessory prayer (IP), social cohesion, coping strategies, the role of chaplains and other clergy or faith leaders, and communal activities such as worship. While evidence for benefits of practices such as IP are inconclusive, patients involved in R/S activities or who hold R/S beliefs appear to have improved coping skills and quality of life (QOL). Although R/S has proven value for patients and surgeons, lack of R/S training is a barrier to surgeon involvement in addressing R/S issues such as operative procedures, treatment plans, organ donation, and end-of-life (EOL) situations. Increased training at the undergraduate, graduate, and post-graduate medical levels concerning R/S would provide surgeons and physician colleagues with skills and greater comfort in discussing these issues with patients and families. .

In the history of cartography and in critical cartography, there is a link between the role of maps and power relations, especially during the conquest and domination of territories by national states. Such cartographic products have frequently been used—for both their scientific and persuasive content—in different places, such as in Chile in the Araucanía region during the so-called pacification process, led by the Chilean state during the second half of the 19th century. From a cartographic perspective, the “epistemological and unintentional silences on the maps” can be observed for maps produced during this process. It implied that the “scientific discourse” and the “social and political discourse” of the cartographic images generated during this process of conquest and domination were relevant for the expansionist objectives of the Republic of Chile.

AbstractIn modern scholarship, much ink has been spilled over the significance of St. Augustine in the history of Western philosophy and theology. However, little effort has been made to clarify the legacy of Augustine in East Asia, especially his contribution to China during the early Jesuit missionary work through the Maritime Silk Road. The present article attempts to fill this lacuna and provide a philosophical analysis of the encounter of Chinese indigenous religions with St Augustine, by inquiring into why and how Augustine was taken as a model for the Chinese in their acceptance of the Christian faith. The analysis is split into three parts. The first part reflects on the contemporary disputations over the quality of the paraphrasing work of the early Jesuits, analyzing the validity of the allegedly careless inaccuracies in their introduction of Augustine's biography. The second part analyses some rarely discussed Chinese translations of Augustine, which I recently found in the Nanjing Union Theological Seminary, with particular focus on their ideological context. In particular, the paraphrased text concerning Augustine's theory of sin and the two cities will be highlighted. The third part goes a step further in exploring the reason why Augustine was considered an additional advantage in dealing with the conflicts between Christian and Confucian values. The primary contribution this essay makes is to present a philosophical inquiry into the role of Augustine in the early acceptance of Christianity in China by suggesting that a strategy of “Confucian-Christian synthesis” had been adopted by the Jesuit missionaries. Thereby, they accommodated Confucian terms without dropping the core values of the orthodox Catholic faith. The conclusion revisits the critics’ arguments and sums up with an evaluation of the impact of Augustine's religious values in the indigenization of Christianity in China.

The article discusses the role of plants in Poland’s economic development over the last 500 years. The author presents the role of five plants in the history of Poland’s development: cereals (wheat and rye), potatoes, sugar beet and rape. The specificity of the economic development of modern Europe has made Poland one of Europe’s granaries and an important exporter of cereals. This shaped the civilization of the Polish-Lithuanian Commonwealth and contributed to its fall due to institutional specificity. In the 19th century, potatoes played an important role in the population development of Polish lands, as they helped feed the rapidly growing population. The spread of sugar beet cultivation created the conditions for the development of modern sugar industry in the second half of the 19th century. It became one of the first modern branches of the food industry in Poland and contributed to the modernization of the village. Quite recently, oilseed rape was to become a plant that would bring back the times of agricultural sheikhs – no longer the nobility would trade in cereals on the European markets, but entrepreneurs producing a vegetable substitute for diesel oil.
