Cost-effective remedial to microfiber pollution from wash effluent in Kolkata and Ranaghat.

The microfibers generated from Polyester and Nylon based materials during washing cause serious environmental pollution by both contaminating the aquatic environment and the livelihood of the underwater creatures as well. This study aims at investigating the microfiber-pollution in wash effluents collected from different regions of Kolkata which is believed to be one of the microfiber-polluted cities in the South-east Asia in recent times. In this work, packed bed microfiltration (PBMF) was adopted in an economic and eco-friendly manner to arrest adequate amounts of microfibers and non-biodegradable matters present in the water samples collected from different regions of Kolkata and its surrounding areas. Moreover, effective parameters such as packed bed height to diameter ratio (H/D), mess size of the adopted filtration unit were varied from 0.71 to 2.85 and 60 to 100, respectively to understand the efficacy of the approach and to justify the potential of such alternative in order to alleviate the concern as well. The present study reveals that the microfiltration efficiency of the proposed PBMF unit was achieved maximum 93.5% for sample A and 92.2% for sample D respectively to reduce the microfiber count from 7614 to 543 in an hour operation at a flow rate of 60 L h-1. Besides, the cost of such system was found to be promising as much as 5 US$ on a yearly basis.

Affective symptoms as a predictor of internet addiction among young adults.

Objectives: Mental health difficulties have been found to be associated with internet addiction, which makes it a multifaceted problem. The current study aimed to examine the relationship between internet addiction and affective states (depression, anxiety, and stress). Material and Methods: The study sample consisted of 731 individuals (403 males and 328 females) ranging in age from 18 to 25 years. We used an observational survey design to study participants with an internet addiction test and depression, anxiety, and stress scale. Results: The mean age ± standard deviation of the sample was 22.58 ± 2.80 years. Stress and depression were found to play a major role in internet addiction in the regression analysis. Conclusions: The study supports the association between internet use and stress and depression. The findings imply the need for early identification and intervention of affective states in the context of unhealthy internet use.

Doomsurfing and doomscrolling mediate psychological distress in COVID-19 lockdown: Implications for awareness of cognitive biases.

The coronavirus disease 2019 (COVID-19) pandemic has led to a significant increase in the consumption of the internet for work, leisure time activities, and has also generated substantial amounts of anxiety, and uncertainty, which has lead individuals to spend a lot of time surfing the internet for the latest news on developments in the COVID-19 crisis. This ends up as scrolling or surfing through a lot of pessimistic news items. This search for information during COVID-19 is apparently influenced by a number of cognitive biases as well as mediated by poor affect regulation skills. Thus, there is a need to address these cognitive biases and promote affect regulation strategies across health settings.

Constructing the understanding of teenagers deviant use of cyberspace.

Cyberspace provides a completely different platform for the expression of one's needs in comparison to the face-to-face world. The use of cyberspace by teenagers is becoming a major concern due to the emergence of engagement in deviant use of internet applications inclusive of engagement in sexting; excessive and addictive use of the internet, consumption of pornography, and as well as phenomena of internet chat rooms. The online disinhibition, anonymity, personality factors, sensation-seeking behavior, impulsivity, deviant socialization processes, and absence of social systems to educate adolescents about gender sensitivity and sex appear to predispose teenagers for indulgence in deviant usage of cyberspace. There is an urgent need to understand the factors related to deviant use of cyberspace and for offering programs for parents and adolescents on gender sensitivity, sexuality, sex, consent in relationships, and deviant use of internet applications. Such initiatives will help to offer opportunities for a corrective experience through appropriate socialization experiences and enhance cyberliteracy among children and adolescents.

Pathways of migration from gaming to gambling.

Gaming and gambling have been studied in terms of similarity of its manifestations. There is a dearth of empirical-based evidence for the exploration of pathways to understand the shift from gaming to gambling. A 23-year-old male from a nuclear family was assessed using clinical interview for the pathways for shifting from gaming to gambling. The pathways were personality predispositions, maladaptive coping, interpersonal distress, peer pressure, variable reward anticipation, addiction characteristics in the form of craving, loss of control and use despite having consequences. These findings suggest that there is a need to create awareness among young adults about these potential causes related to transition from gaming to gambling.
