Social media induced polarisation (SMIP) poses serious challenges to society as it could enable ‘digital wildfires’ that can wreak havoc worldwide. While the effects of SMIP have been extensively studied, there is limited understanding of the interplay between two key components of this phenomenon: confirmation bias (reinforcing one’s attitudes and beliefs) and echo chambers (i.e., hear their own voice). This paper addresses this knowledge deficit by exploring how manifestations of confirmation bias contributed to the development of ‘echo chambers’ at the height of the Covid-19 pandemic. Thematic analysis of data collected from 35 participants involved in supply chain information processing forms the basis of a conceptual model of SMIP and four key cross-cutting propositions emerging from the data that have implications for research and practice.

Pyrolysis has emerged as one of the best waste management technique for energy extraction from the plastic waste. The objective of this work is to investigate the effect of operating temperature on the liquid product yields in the pyrolysis process by non-isothermal heating. Non-catalytic thermal pyrolysis of waste polyethylene (PE) [high density polyethylene (HDPE)], waste polypropene (PP), waste polystyrene (PS), waste polyethylene terephthalate (PET) and mixed plastic waste (MPW) was carried out in a non-sweeping atmosphere in a semi-batch reactor at four different temperatures 450, 500, 550, and 600°C. The minimum degradation temperature of the mixed and individual plastics was obtained using a thermogravimetric apparatus (TGA) at a heating rate of 20°C/min. The TGA results show that all plastics degrade in a single step and the degradation temperatures of PS > PET > PP > HDPE, while mixed plastic degradation indicates two distinct degradation steps. Further, a waste polymer shows a lower degradation temperature than the virgin polymer. The degradation of HDPE is found to produce the maximum oil yield with minimum solid residue. The degradation of PET results in the highest amount of solid and benzoic acid as crystals and gas with no oil. Degradation of mixed plastic causes oil yield in the intermediate range of pyrolysis of individual plastic wastes. Overall, 500°C is observed to be an optimum temperature for the recovery of low-density pyrolytic oil with the highest liquid yield. The degradation of PE and PP is found to be caused by random chain scission followed by inter and intramolecular hydrogen transfer. The degradation of PS occurs by side elimination or end chain scission followed by β-scission mechanism. The degradation of mix plastics results from random chain scission followed by β-scission mechanism. The effect of temperature on oil and gas recovery as well as recovery time was also assessed.

Although several delivery vehicles, including cell-penetrating peptides, have been developed, their implementation is often restricted because of their endosomal entrapment. Herein, we report the formation of self-assembled nanostructures from rationally designed cyclic peptides and explore them for efficient delivery of functional biomacromolecules such as siRNA into mammalian cells. The newly obtained soft materials make stable complexes with siRNAs, thereby increasing their stability and deliver fluorescent labelled siRNA inside the cells as evident from confocal microscopy analysis. Flow cytometry analysis reveals that significant uptake of FAM-siRNA occurs in the presence of peptide nanostructures compared with siRNA alone. Peptide nanostructure-mediated delivery of very low concentration of siRNA causes significant knockdown of the target ge...

Ego state model basically consist of three ego states namely parent, adult and child ego state developed by Eric Berne which specifies communication between the persons under the influence of same or different ego state. In this study we analyzed behaviour of employees in different ego state and significant impact of their attitude and behaviour on their job performance. This study reveals that each employee has all three ego states but it switch from one ego state to another, it‟s all depend on person‟s comfort with any ego state for a particular period of time and the type of attitude he/she inherit under any ego state. In any organization the anger and happiness is the result of communication between the employees under different ego state. Effective communication among the employees is possible only when a employee in a one ego state e...

In the present study, authors have reviewed the intense literature to extract all possible dimensions of motivation, having direct and indirect impact on motivation techniques. This has examined the multidimensionality of motivation from the existing literature and present a conceptual framework based on it, and it is experienced that various motivation techniques (discussed in this study) are having a positive impact on both employee satisfaction and the quality of performance in the organization; however, the model needs to be validated using quantitative measures. In order to study the various issues highlighted in this paper related to employee motivation, a large body of literature mainly from different journals have been incorporated. To make the study more current only those studies were included which were published in the last two decades. In past research papers few dimensions of motivation were used to explain the different models motivation theory which has direct influence on employee motivation. The novelty of this study lies in its theoretical framework where authors have made an attempt to come up with a construct having dimensions that directly or indirectly influences employee motivation.

Pediatric CC has been associated with more aggressive clinical and radiological patterns than their adult counterparts. In this study, undertaken on children with anterior third ventricular CC, excised using the interhemispheric transcallosal approach, the characteristic clinicoradiological features and management options are studied. Methods Five pediatric patients (aged 16 years or less; mean age 13.8 years; mean duration of symptoms:7.6 months) out of 38 patients with CC operated between 1995 to 2009 were included. The clinical manifestations included those of raised intracranial pressure (n=4); exacerbation of occipital headache on reading (n=1); secondary optic atrophy (n=3); and, drop attacks (n=1). On computed tomography scan, the cyst was hyperdense, enhancing in two patients and not enhancing in three patients. All had bilateral lateral ventricular dilatation with periventricular lucency. On magnetic resonance imaging (n=3), the cyst was T1 hypointense and T2 isointense in one, hyperintense on both T1 and T2 with a

Supply chain is a dynamic function of organization that changes with time, there are several factors that influences its performance. Each organization has its unique supply chain structure so the critical factors that influence its performance also vary from organization to organization. Till date many researchers have given their insights towards supply chain performance management. In this paper we did a critical review of previously done researches and find out the critical factors having their significant impact on supply chain performance. The paper also made a summary discussion on the performance measurement tools popular among researchers such as AHP, DEA, BSC, SCOR etc
