Calculating trust using multiple heterogeneous social networks
No full textIn today's Internet, a web user becomes members of multiple social networks due to different types of services provided by each of these networks. This creates an opportunity to make trust decisions that go beyond individual social networks, since these networks provide single perspective of trust. To make trust inference over multiple social networks, these networks need to be consolidated. It is nontrivial as these networks are of heterogeneous nature due to different naming conventions used in these networks. Furthermore, trust metrics extracted from these networks are also varied in nature due to different trust evaluation algorithms used in each of these networks. Heterogeneity of these social networks can be overcome by using semantic technologies as it allows us to represent knowledge using ontologies. Trust data can be consolidated by using such data fusion techniques which not only provide but also preserve trust data integrity from each of the individual social network profiles. The proposed semantic framework is evaluated using two sets of experiments. Through simulations in this work, we analysed various techniques for data fusion. For identifying suitable technique that preserves the integrity of trust consolidated from each of the individual networks, analysis revealed that Weighted Ordered Weighted Averaging parameter best aggregated trust data, and, unlike other techniques, it preserved the integrity of trust from each individual network for varying participant overlap and tie overlap (p≤0.05). Similarly, for experimental analysis, we used findings of the simulation study about the best trust aggregation technique and applied the proposed framework on real-life trust data between participants, which we extracted from pairs of professional social networks. Analysis partially proved our hypothesis about generating better trust values from consolidated multiple heterogeneous networks. We witnessed an improvement in overall results for all the participants who were part of multiple social networks (p≤0.05), while disproving the claim for those existing in nonoverlapping regions of the social networks.</p
The Translocation of Culture: Migration, Community, and the Force of Multiculturalism in History
No full textIn his work on a Welsh border village, Ronald Frankenberg showed how cultural performances, from football to carnival, conferred agency on local actors and framed local conflicts. The present article extends these themes. It responds to invocations by politicians and policy makers of ‘community cohesion’ and the failure of communal leadership, following riots by young South Asians in northern British towns. Against the critique of self-segregating isolationism, the article traces the historical process of Pakistani migration and settlement in Britain, to argue that the dislocations and relocations of transnational migration generate two paradoxes of culture. The first is that in order to sink roots in a new country, transnational migrants in the modern world begin by setting themselves culturally and socially apart. They form encapsulated ‘communities’. Second, that within such communities culture can be conceived of as conflictual, open, hybridising and fluid, while nevertheless having a sentimental and morally compelling force. This stems from the fact, I propose, that culture is embodied in ritual and social exchange and performance, conferring agency and empowering different social actors: religious and secular, men, women and youth. Hence, against both defenders and critics of multiculturalism as a political and philosophical theory of social justice, the final part of the article argues for the need to theorise multiculturalism in history. In this view, rather than being fixed by liberal or socialist universal philosophical principles, multicultural citizenship must be grasped as changing and dialogical, inventive and responsive, a negotiated political order. The British Muslim diasporic struggle for recognition in the context of local racism and world international crises exemplifies this process. Classification-
Studies on Genetic Divergence of Rapeseed Genotypes Using SSR Markers
No full textThirty five Brassica napus genotypes were evaluated to check their genetic diversity on the basis of mapped 20 microsatellite markers. The genetic similarity values of coefficient ranged from 0.28 to 0.85. A dendrogram was generated based on UPGMA which showed that genotypes were divided into five major clusters. Cluster A had genotypes with higher similarity coefficient of 0.85 while Cluster E had only one genotype (pop 35) genetically distinct from other genotypes. PIC values were calculated for each of the 20 SSR primer pairs. Ten primers PIC value ranged from 0.30 (O110-A05) to 0.59 (Na10-D09 markers). This study would be helpful in assessing the genetic diversity. It was revealed that there was no correlation between the geographical distribution and genetic diversity of the studied germplasm, depicting their close genetic relationship
Performance of Cs-Doped Carbon-Based Perovskite Solar Cells in Ambient Environment
No full textThe development of organometal halide-based perovskite solar cells (PSCs) has made remarkable progress in photovoltaics. The commercialization of PSCs is still significantly limited, owing to their poor stability and the high material cost of a hole transport layer (HTL) and metal electrodes. To counter these issues, a carbon-based HTL and noble metal-free PSCs are being used. In this work, the effect of Cs-doping on perovskite film morphology and device performance has been systematically studied because the Cs+ and Br− ions-doping has proved to be a good choice to improve the stability of PSCs in combination with a carbon electrode. The results showed that when the Cs-doping concentration in perovskite film, MA1−xCsxPb(I1−yBry)3, was equal to x = 0.09, there was a substantial change in the morphological and optoelectronic properties of perovskite films. The grain size of perovskite films was improved from 70 nm (x = 0.00 control) to 170 nm (x = 0.09 Cs-doped), reducing grain boundaries. Moreover, the trap states were additionally passivated resulting in improved radiative recombinations in the perovskite film. The device fabrication was carried out in a controlled dry glovebox, with relative humidity < 40% using carbon as a counter electrode. As a result, Cs-doped PSCs showed a significant increase in efficiency (5.27%) compared to control PSCs (1.55%)

No full textIndividual and synergistic effects of different fertilizers and gibberellin on growth and morphology of chili seedlings
No full textGibberellins (GA₃), as well as the basic elements phosphorus (P), nitrogen (N), and potassium (K), are crucial to the growth of chili. This study investigates the effect of different fertilizers and plant growth regulator on the growth and morphology of chili seedlings. Soil application of NPK, urea, SOP, and DAP (2.5 g/L) was applied during sowing, and N in two splits at sowing and after twenty days of sowing while foliar application of GA₃ (50 mg/L) was applied after fifteen days of germination. The result of five seedlings' traits plant height (PH), plant girth (PG), plant spread (PS), number of leaves (NOF), and root length (RL) demonstrated a significant difference among growth-related traits in chili seedlings owing to the use of fertilizers, GA₃, and their combinations. An optimum level of K and P alone or in combination with GA₃ had a significant effect on all traits. PH was particularly influenced by the combination of GA₃ with K and P whereas other traits like PG, NOF, PS, and RL are greatly influenced by the application of NPK, urea, SOP, DAP, and their combination with GA₃. The study results showed an increase in chili seedlings' growth and morphology in response to various fertilizers and GA₃.Iza Fatima, Aiman Fatima, Muhammad Aqib Shah, Muhammad Amjad Farooq, Iftikhar Ali Ahmad, Irsa Ejaz, Daniel Adjibolosoo, Ume Laila, Muhammad Asim Rasheed, Ans Imran Shahid, Ayesha Tariq, Ume Han
