Review
Grit, which is originally conceptualized as passion and perseverance for long-term goals, has been associated with optimal performance. Although previous meta-analytic and systematic reviews summarized how grit relates to performance outcomes, they possess considerable shortcomings, such as (a) absence of summary on the association of grit with well-being outcomes; (b) absence of discussion on social, psychological, and emotional mechanisms linking grit to well-being; and (c) lack of elaboration on how alternative models can resolve fundamental problems in the grit construct. This integrative review provides a comprehensive summary on the link of grit to performance and well-being outcomes. Importantly, it elaborates how alternative models can potentially address flaws in the existing grit theory. Future research directions are discussed on how to move forward the science of grit.

BACKGROUND
The impact of qualitative olfactory disorders is underestimated. Parosmia, the distorted perception of familiar odors, and phantosmia, the experience of odors in the absence of a stimulus, can arise following postinfectious anosmia, and the incidences of both have increased substantially since the outbreak of COVID-19.
OBJECTIVE
The aims of this study are to explore the symptoms and sequalae of postinfectious olfactory dysfunction syndrome using unstructured and unsolicited threads from social media, and to articulate the perspectives and concerns of patients affected by these debilitating olfactory disorders.
METHODS
A thematic analysis and content analysis of posts in the AbScent Parosmia and Phantosmia Support group on Facebook was conducted between June and December 2020.
RESULTS
In this paper, we identify a novel symptom, olfactory perseveration, which is a triggered, identifiable, and usually unpleasant olfactory percept that persists in the absence of an ongoing stimulus. We also observe fluctuations in the intensity and duration of symptoms of parosmia, phantosmia, and olfactory perseveration. In addition, we identify a group of the most common items (coffee, meat, onion, and toothpaste) that trigger distortions; however, people have difficulty describing these distortions, using words associated with disgust and revulsion. The emotional aspect of living with qualitative olfactory dysfunction was evident and highlighted the detrimental impact on mental health.
CONCLUSIONS
Qualitative and unsolicited data acquired from social media has provided useful insights into the patient experience of parosmia and phantosmia, which can inform rehabilitation strategies and ongoing research into understanding the molecular triggers associated with parosmic distortions and research into patient benefit.

BACKGROUND
Desire thinking is a conscious and voluntary cognitive process that is closely linked to levels of craving and addictive behaviors. The Desire Thinking Questionnaire (DTQ) can be used to measure desire thinking in all age groups as well as in addicts. This measurement has also been translated into several languages. This study aimed to test the psychometric properties of the Chinese version of the DTQ (DTQ-C) among adolescent mobile phone users.
METHODS
One thousand and ninety-seven adolescents who own a mobile phone and are younger than 18 years old completed the DTQ-C and a battery of questionnaires assessing the big five personality traits, negative affect, brooding, self-control, craving, and problematic mobile phone use (PMPU). The psychometric analyses of the DTQ-C were conducted, including exploratory factor analysis (EFA), confirmatory factor analysis (CFA), reliability, and validity analysis.
RESULTS
The EFA revealed a 10-item two-factor structure (i.e., verbal perseveration and imaginal prefiguration) that was confirmed by the CFA. The results of CFA showed fit indexes of χ/df = 4.83, CFI = 0.967, TLI = 0.954, RMSEA = 0.059, SRMR = 0.032. The total scale had internal consistency reliabilities of 0.93, which demonstrated that DTQ-C presented good reliability. The two dimensions were correlated with PMPU (r = 0.54; r = 0.45), neuroticism (r = 0.18; r = 0.14), conscientiousness (r = -0.19; r = -0.18), depression (r = 0.22; r = 0.16), anxiety (r = 0.26; r = 0.22), stress (r = 0.15; r = 0.10) and self-control (r = -0.29; r = -0.26), which demonstrated that DTQ-C presented good concurrent validity. The two factors of DTQ-C correlated weakly with brooding (ranging from 0.08 to 0.10). The principal component factor analysis of the two dimensions of desire thinking and craving showed that craving and desire thinking belonged to different dimensions. Both of which showed good divergent validity of desire thinking. Additionally, an examination of incremental validity revealed that two factors were both positively associated with PMPU beyond demographic characteristics, big five personality traits, negative affect, and self-control (B = 0.49 and B = 0.13).
CONCLUSIONS
It has been found that the 10-item DTQ-C is a reliable and valid measure of desire thinking in Chinese adolescent mobile phone users.

How does emotion regulation in one social context spillover to functioning in another? We investigate this novel question by drawing upon recent evidence that 3 categories underpin the most commonly assessed emotion regulation strategies: disengagement, aversive cognitive perseveration, and adaptive engagement. We examine how these emotion regulation categories during marital conflict are associated with conflict resolution and assess the associated implications for functioning during a subsequent family activity. We also develop and compare observational and self-report measures of emotion regulation. Couples (N = 101) were video-recorded discussing a major conflict and reported on their emotion regulation during the discussion. Couples then participated in a family activity with their 5-year-old child, and reported on the quality of the family experience and responsiveness toward their child. Observational coders rated how much each participant exhibited each type of emotion regulation during the conflict discussion. Greater disengagement and aversive cognitive perseveration were associated with lower conflict resolution, and in turn, less positive experiences and poorer parental responsiveness during the family activity. Greater adaptive engagement had the opposite effects, but only disengagement and aversive cognitive perseveration had independent effects when controlling for the other emotion regulation categories. Finally, observational and self-report measures were only weakly associated, but illustrated the same pattern of effects. These novel findings suggest that emotion regulation strategies have important flow-on effects beyond the context initially enacted. The results also indicate that self-report versus observed measures of emotion regulation reveal similar patterns, but may capture different intrapersonal and interpersonal elements of emotion regulation.

Review
Due to its resistance to natural degradation and decomposition, plastic debris perseveres in the environment for centuries. As a lucrative material for packing industries and consumer products, plastics have become one of the major components of municipal solid waste today. The recycling of plastics is becoming difficult due to a lack of resource recovery facilities and a lack of efficient technologies to separate plastics from mixed solid waste streams. This has made oceans the hotspot for the dispersion and accumulation of plastic residues beyond landfills. This article reviews the sources, geographical occurrence, characteristics and recyclability of different types of plastic waste. This article presents a comprehensive summary of promising thermochemical technologies, such as pyrolysis, liquefaction and gasification, for the conversion of single-use plastic wastes to clean fuels. The operating principles, drivers and barriers for plastic-to-fuel technologies via pyrolysis (non-catalytic, catalytic, microwave and plasma), as well as liquefaction and gasification, are thoroughly discussed. Thermochemical co-processing of plastics with other organic waste biomass to produce high-quality fuel and energy products is also elaborated upon. Through this state-of-the-art review, it is suggested that, by investing in the research and development of thermochemical recycling technologies, one of the most pragmatic issues today, i.e., plastics waste management, can be sustainably addressed with a greater worldwide impact.

Review
There is an ongoing debate about the potential risks and benefits of long-term antipsychotic treatment in schizophrenia. The data for and against the chronic use of these medicines is mostly indirect, either from observational studies potentially exposed to reverse causation bias or randomized controlled studies that do not cover beyond 2-3 years. We propose that perseverating on the question of what positive or negative outcomes are causally associated with chronic antipsychotic treatment may not lead to better answers than the limited ones that we have, given the limited feasibility of more conclusive studies. Rather, we argue that addressing the research question of the risks and benefits of antipsychotic discontinuation from a perspective of personalized medicine, can be more productive and meaningful to people living with schizophrenia. To this end, research that can quantify the risk of relapse after treatment continuation for a given individual should be prioritized. We make the case that clinically feasible neuroimaging biomarkers have demonstrated promise in related paradigms, and that could be offering a way past this long debate on the risks and benefits of chronic antipsychotic use.

Gambling disorder (GD) is a behavioral addiction associated with impairments in value-based decision-making and behavioral flexibility and might be linked to changes in the dopamine system. Maximizing long-term rewards requires a flexible trade-off between the exploitation of known options and the exploration of novel options for information gain. This exploration-exploitation trade-off is thought to depend on dopamine neurotransmission. We hypothesized that human gamblers would show a reduction in directed (uncertainty-based) exploration, accompanied by changes in brain activity in a fronto-parietal exploration-related network. Twenty-three frequent, non-treatment seeking gamblers and twenty-three healthy matched controls (all male) performed a four-armed bandit task during functional magnetic resonance imaging (fMRI). Computational modeling using hierarchical Bayesian parameter estimation revealed signatures of directed exploration, random exploration, and perseveration in both groups. Gamblers showed a reduction in directed exploration, whereas random exploration and perseveration were similar between groups. Neuroimaging revealed no evidence for group differences in neural representations of basic task variables (expected value, prediction errors). Our hypothesis of reduced frontal pole (FP) recruitment in gamblers was not supported. Exploratory analyses showed that during directed exploration, gamblers showed reduced parietal cortex and substantia-nigra/ventral-tegmental-area activity. Cross-validated classification analyses revealed that connectivity in an exploration-related network was predictive of group status, suggesting that connectivity patterns might be more predictive of problem gambling than univariate effects. Findings reveal specific reductions of strategic exploration in gamblers that might be linked to altered processing in a fronto-parietal network and/or changes in dopamine neurotransmission implicated in GD. Wiehler et al. (2021) report that gamblers rely less on the strategic exploration of unknown, but potentially better rewards during reward learning. This is reflected in a related network of brain activity. Parameters of this network can be used to predict the presence of problem gambling behavior in participants.

Perseverative thinking (PT), or repetitive negative thinking, has historically been measured using global self-report scales. New methods of assessment are needed to advance understanding of this inherently temporal process. We developed an intensive longitudinal method for assessing PT. A mixed sample of 77 individuals ranging widely in trait PT, including persons with PT-related disorders (generalized anxiety disorder, major depression) and persons without psychopathology, used a joystick to provide continuous ratings of thought valence and intensity following exposure to scenarios of differing valence. Joystick responses were robustly predicted by trait PT, clinical status, and stimulus valence. Higher trait perseverators exhibited more extreme joystick values overall, greater stability in values following threatening and ambiguous stimuli, weaker stability in values following positive stimuli, and greater inertia in values following ambiguous stimuli. The joystick method is a promising measure with the potential to shed new light on the dynamics and precipitants of perseverative thinking.

Life, whatsoever it is, is a temporal flux. Everything is doomed to change often apparently beyond our awareness. My body appears totally different now, so does my mind. I have gained new attitudes and new ambitions, and a substantial number of old ones have been discarded. But, I am still the same person in an ongoing manner. Besides, recent neuroscientific and psychological evidence has shown that our conscious perception happens as a series of discrete or bounded instants-it emerges in temporally scattered, gappy, and discrete forms. But, if it is so, how does the brain persevere our self-continuity (or continuity of identity) in this gappy setting? How is it possible that despite moment-to-moment changes in my appearance and mind, I am still feeling that I am that person? How can we tackle with this second by second gap and resurrection in our existence which leads to a foundation of wholeness and continuity of our ? How is continuity of self (collective set of our connected experiences in the vessel of time) that results in a feeling that one's life has purpose and meaning preserved? To answer these questions, the problem has been comprehended from a philosophical, psychological, and neuroscientific perspective. I realize that first and foremost fact lies in the temporal nature of identity. Having equipped with these thoughts, in this article, it is hypothesized that according to two principles (the principle of reafference or corollary discharge and the principle of a time theory) self-continuity is maintained. It is supposed that there should be a precise temporal integration mechanism in the CNS with the outside world that provides us this smooth, ungappy flow of the . However, we are often taken for granted the importance of self-continuity, but it can be challenged by life transitions such as entering adulthood, retirement, senility, emigration, and societal changes such as immigration, globalization, and in much unfortunate and extreme cases of mental illnesses such as schizophrenia.
