A Critical Analysis of Conversational Floors In Post- Corona Digital Discourse Among Pakistani Students

Abstract: This article intends to investigate conversational patterns of communication in multi-participant text-based digital discourse in the post-corona scenario. Much of ComputerMediated Communication (CMC) research motivated the researchers to understand how computer mediation and cellular phones influence human conversation. This research is inspired by the conversational floors discussed by Simpson (2005). In this present study, the researchers focus on the WhatsApp groups created for Academic purposes among English-major students in Pakistan after a sudden outbreak of coronavirus (henceforth, COVID-19). WhatsApp, primarily developed in 2009 as an informal instant chat app. It has widely been used by youth worldwide. Manufacturers of WhatsApp brought many changes in its format and introduced many new features over the years, i.e., written text messages, audio recordings, picture and video sharing, use of emoticons, document sharing, and status updating. Soon after realizing the liking of people for instant messaging application, WhatsApp launched 2.0 in its beta stage (Pahwa, 2019). People love the notion of using WhatsApp for sending messages via the internet instead of using the Operator's SMS plans by using just phone numbers. This is how WhatsApp replaced SMS and emails in many countries like Pakistan. In Pakistan, WhatsApp has been used for both formal and informal purposes. Consequently, right after the widespread of the novel coronavirus in March 2020 leading to the suspension of traditional classes, the university teachers and students in Pakistan moved to WhatsApp instantly to resume Academic Abstract: This study investigates the pattern of conversational floors of digital discourse in WhatsApp groups among Pakistan's students after the outbreak of Covid-19. Gender differences were also focused while generating digital discourse in the post corona scenario. Non-probability sampling techniques are used, as our research design is qualitative. Data is taken from universities of Punjab and is in the form of interviews and screenshots of students' five days chat in Whatsapp groups. Researchers chiefly focused on conversational floors, gender roles, and post corona discourse. Results show the effects of Covid-19 as students have problems involving in more meaningful conversations, and due to conflicts among members, a breakdown in communication occurs. The connection between argumentation and floor holding gives a deep analysis of the dynamics of online discussion. From the gender perspective, males maintained the central stage in noncollaborative discourse while there are almost equal or more active females in collaborative discourse.

Dividend Payment Decision and Earned/Contributed Capital Mix: A Test of Life Cycle & Catering Theory

Abstract: Purpose of this research is to examine the effects of catering incentives and earn contributed capital mix on propensity to pay and decision to change dividend for Pakistani manufacturing concerns. Basic intent is to validate the most recently developed dividends theories with respect to Pakistani sample i.e. catering theory and Life Cycle Theory. This research is conducted on Pakistani non-financial companies duly listed on Karachi stock exchange from 1998 to 2009. Catering theory is measured by dividend premium, life cycle theory is measured by earned contributed capital mix, while the proxy used to measures dividend payment decisions are propensity to pay, and decisions to change dividend. Company’s age, Growth prospects, Market to book ratio, profitability, cash holding have positive impact on dividend increasing companies and negative to dividend decreasing. While catering incentives, taxation and leverage has negative impact on dividend paying companies vice versa for Decreasing and dividend omitting companies. Results confirm that catering theory holds in developing economy like Pakistan while life cycle theory provides little evidence. Pakistani stock exchange crises pose little effects on investors mind.

Energy of Bipolar Fuzzy Graphs

Abstract: In this chapter, we study the concept of energy of bipolar fuzzy graphs and present certain formulae, lower and upper bounds of Laplacian energy, signless Laplacian energy, dominating energy, out-dominating energy, double dominating energy, and double out-dominating energy of bipolar fuzzy graphs and bipolar fuzzy digraphs. We elaborate the presented concept of energy and its extensions with numerical and graphical examples. Using bipolar fuzzy preference relations, we present multi-criteria decision-making models based on the energy of bipolar fuzzy graphs in business partnerships and smooth communication problems. The main results of this chapter are from [3, 4, 14].

Structure-Based Designing, Solvent Less Synthesis of 1,2,3,4-Tetrahydropyrimidine-5-carboxylate Derivatives: A Combined In Vitro and In Silico Screening Approach.

Abstract: Objective: In this study, small molecules possessing tetrahydropyrimidine derivatives have been synthesized having halogenated benzyl derivatives and carboxylate linkage. As previously reported, FDA approved halogenated pyrimidine derivatives prompted us to synthesize novel compounds in order to evaluate their biological potential. Methodology: Eight pyrimidine derivatives have been synthesized from ethyl acetoacetate, secondary amine, aromatic benzaldehyde by adding catalytic amount of CuCl2·2H2O via solvent less Grindstone multicomponent reagent method. Molecular structure reactivity and virtual screening were performed to check their biological efficacy as an anti-oxidant, anti-cancer and anti-diabetic agent. These studies were supported by in vitro analysis and QSAR studies. Results: After combined experimental and virtual screening 5c, 5g and 5e could serve as lead compounds, having low IC50 and high binding affinity.

MicroRNAs as Targets of Dietary Phytochemicals in Obesity and Cancer

Abstract: MicroRNAs (miRNAs) are minute regulatory single stranded noncoding molecules (about 22 nucleotides) of ribonucleic acids that influence expression of gene all the way through posttranscription. They are known to control different biological processes for example differentiation of cell, survival, development, migration, their dysregulation and death of cells. There are excess of over 500 miRNAs with different roles in the human body. In this chapter, effort was made to discuss the potential roles of miRNA in obesity and cancer and how dietary phytochemicals modulate them.
