A Lie theoretic categorification of the coloured Jones polynomial

We use the machinery of categorified Jones-Wenzl projectors to construct a categorification of a type A Reshetikhin-Turaev invariant of oriented framed tangles where each strand is labeled by an arbitrary finite-dimensional representation. As a special case, we obtain a categorification of the coloured Jones polynomial of links

CORRELATES BETWEEN PARENTING STYLES AND THE EMOTIONAL INTELLIGENCE: A STUDY OF SENIOR SECONDARY SCHOOL STUDENTS IN LAGOS STATE

Background: Emotional intelligence is a relatively recent behavioural model, rising to prominence with the work of Daniel Goleman. The study of parent-child relations has grown tremendously in recent years coupled with its implication on the emotional intelligence of students. This study examined the influence of parenting styles on emotional intelligence of senior school students in Lagos State, the commercial capital of Nigeria and a metropolitan city. Methods: Two hundred and fifty (250) students were randomly selected from five selected schools with age ranging from 15 to 19 years (mean age = 17 years) through stratified and systematic sampling techniques. The study being a survey research, made use of a questionnaire consisting of two validated subscales; the Trait Emotional Intelligence Questionnaire (TEIQue) and the Parenting Style Inventory (PSI). Three hypotheses were raised and tested. Hypotheses one and three were analyzed using Pearson’s product moment correlation while regression analysis was employed to analyze hypothesis two. Result: In testing the relationship between parenting styles and emotional intelligence, result shows that father’s authoritative parenting style (r = 0.152, p < .005) and mother’s authoritative parenting style (r = 0.227, p < .01) contributed to the prediction of emotional intelligence. Regression analysis shows that of the six predictor variables, only mother’s authoritative parenting style (β = 1.952, t = 2.345, p<.05) could significantly predict the emotional intelligence of senior school students. Conclusion: Being emotionally intelligent adds value to life. Emotions are important to our everyday lives; hence, young people should be assisted on how to control their emotions. Parents, teachers and significant others need to provide guidance for the development emotional intelligence of these young impressionable students

Tissue Localization and Extracellular Matrix Degradation by PI, PII and PIII Snake Venom Metalloproteinases: Clues on the Mechanisms of Venom-Induced Hemorrhage

20 páginas, 4 figuras, 3 tablas y 7 tablas en material suplementario.Snake venom hemorrhagic metalloproteinases (SVMPs) of the PI, PII and PIII classes were compared in terms of tissue localization and their ability to hydrolyze basement membrane components in vivo, as well as by a proteomics analysis of exudates collected in tissue injected with these enzymes. Immunohistochemical analyses of co-localization of these SVMPs with type IV collagen revealed that PII and PIII enzymes co-localized with type IV collagen in capillaries, arterioles and post-capillary venules to a higher extent than PI SVMP, which showed a more widespread distribution in the tissue. The patterns of hydrolysis by these three SVMPs of laminin, type VI collagen and nidogen in vivo greatly differ, whereas the three enzymes showed a similar pattern of degradation of type IV collagen, supporting the concept that hydrolysis of this component is critical for the destabilization of microvessel structure leading to hemorrhage. Proteomic analysis of wound exudate revealed similarities and differences between the action of the three SVMPs. Higher extent of proteolysis was observed for the PI enzyme regarding several extracellular matrix components and fibrinogen, whereas exudates from mice injected with PII and PIII SVMPs had higher amounts of some intracellular proteins. Our results provide novel clues for understanding the mechanisms by which SVMPs induce damage to the microvasculature and generate hemorrhage.This work was performed in partial fulfillment of the requirements for the PhD degree for Cristina Herrera at Universidad de Costa Rica.Peer reviewe

Content and Feedback Analysis of YouTube Videos: Football Clubs and Fans as Brand Communities

The use of Web 2.0 tools has been transforming the interaction between companies and their clients, especially for those that are selling emotional products. Consumers are generating and sharing contents concerning their favourite products on the web. Even if this process has been widely acknowledged, only a few studies have been specifically devoted to the analysis of both the contents and the feedback the consumers receive from other users. This article analyzes the online presence of sport brands through contents that are generated by sport clubs (official contents) and their fans (User Generated Content, UGC) on YouTube. After a description and classification of video contents, it examines the factors that influence the performance of the videos in terms of passive (videos views) and active behaviour (any kinds of interaction with videos) among the viewers. In order to carry out this analysis, 125 YouTube channels were considered thereby accounting for a total of 375 videos. Results show that official contents are those preferred by the users/consumers and that if the video displays a passive/purely informative content, the chance of getting an active behaviour from the users tends to decrease. These findings may help companies manage their online presence, creating awareness about contents and information that should be spread and shared on the web
