Digital media elements, or digital assets, are used to illustrate things such as images, sounds, or events. As humans, we use many senses to assist our cognitive processes, and providing multiple representations will enhance our ability to store, recall, and synthesise the knowledge and information contained in the digital asset. This chapter introduces a model for a multimedia object, that allows multiple representations to be managed, and includes a structured metadata file describing the asset that captures the original context. Humans are capable of classifying and describing millions of such objects, but recalling context and content often blurs over time. Computer systems provide us with a way to store electronic objects, and with a variety of representations and sufficient metadata they can be used to assist cognitive recall.

Abstract. Escalation of commitment occurs when a course of action is continued despite repeated drawbacks (e.g., maintaining an employment relationship despite severe performance problems). We analyze process accountability (PA) as a de-escalation technique that helps to discontinue a failing course of action and show how time moderates both the behavioral and cognitive processes involved: (1) Because sound decisions should be based on (hopefully unbiased) information search, which requires time to gather, the effect of PA on de-escalation increases over time. (2) Because continuing information search creates behavioral commitment, the debiasing effect of PA on information search diminishes over time. (3) Consistent with the tunnel vision notion, the effects of less biased information search on de-escalation decrease over time.

One of the most relevant methods used in the rehabilitation of hearing-impaired children and for the development of speech is music-rhythm. In any games based on music-rhythm, it is possible to stimulate several areas, such as speech, motor, cognitive processes. Composing tasks in the form of role-playing games appropriate to the age characteristics of children increases its effectiveness. Music primarily affects the auditory analyzer in children, helps to increase auditory attention in children with dementia. Thus, the child perceives sounds better over time and develops the ability to differentiate them. Improved hearing allows children to understand the speech of adults better. Over time, it accelerates the process of sound imitation, allows the child to pronounce the initial sounds and syllables. Musical-rhythmic is based on the combination of sounds with movements, which leads to the improvement of children's motor skills. It helps to develop small and large motor skills, rhythm and coordination abilities during tasks. Key words: hearing, speech, game, music, exercise, child

The growth of the digital asset ecosystem has led to the emergence of hundreds of crypto exchanges that facilitate the trade of digital assets. This phenomenon did not remain without the attention of malefactors. Today, we can talk about an independent type of “cryptocurrency exchange crime”. The article analyzes the key criminal trends and formulates the main recommendations for the prevention of criminal encroachments in the cryptocurrency market. At the moment, one of the most common manipulative schemes is “pump and dump”, which became notorious at the turn of the 90s and 2000s. To date, no jurisdiction has created an effective protection regime against such fraud. The authors highlight the main reasons for the low efficiency of the measures taken: the presence of digital assets on the Internet led to the online nature of all stages of manipulations coordinated by anonymous groups in social networks; wide availability and lack of restrictions on the placement of tokens predetermined their regular and widespread placement (as opposed to an IPO); selfish interest of crypto-exchange sites that receive a commission from a transaction. It is emphasized that regulators’ search for a balance between innovation and investor protection is driving the reluctance of many jurisdictions to introduce proper criminal law protection regimes.

High rates of obesity in Latinas highlight the need to determine if physical activity interventions are equally effective across the body mass index (BMI) range. Thus, this study assessed how BMI impacts success of Spanish-speaking Latinas in a culturally and linguistically adapted theory-based physical activity intervention (). Longitudinal regression models tested the relationship between baseline BMI and outcomes. Overall, a trend for a negative association was found between baseline BMI and self-reported physical activity and theoretical constructs targeted by the intervention over time. For example, someone with a 25 kg/m2BMI would report, on average, 27.5 more minutes/week of activity compared to someone with a 30 kg/m2BMI at followup. Furthermore, higher baseline BMI was significantly associated with lower self-efficacy, behavioral and cognitive processes of change, and family social support over time. These findings suggest that participants with higher BMI may need additional intervention to promote physical activity.

The prosperity of the cryptocurrency ecosystem drives the need for digital asset trading platforms. Beyond centralized exchanges (CEXs), decentralized exchanges (DEXs) are introduced to allow users to trade cryptocurrency without transferring the custody of their digital assets to the middlemen, thus eliminating the security and privacy issues of traditional CEX. Uniswap, as the most prominent cryptocurrency DEX, is continuing to attract scammers, with fraudulent cryptocurrencies flooding in the ecosystem. In this paper, we take the first step to detect and characterize scam tokens on Uniswap. We first collect all the transactions related to Uniswap V2 exchange and investigate the landscape of cryptocurrency trading on Uniswap from different perspectives. Then, we propose an accurate approach for flagging scam tokens on Uniswap based on a guilt-by-association heuristic and a machine-learning powered technique. We have identified over 10K scam tokens listed on Uniswap, which suggests that roughly 50% of the tokens listed on Uniswap are scam tokens. All the scam tokens and liquidity pools are created specialized for the "rug pull" scams, and some scam tokens have embedded tricks and backdoors in the smart contracts. We further observe that thousands of collusion addresses help carry out the scams in league with the scam token/pool creators. The scammers have gained a profit of at least $16 million from 39,762 potential victims. Our observations in this paper suggest the urgency to identify and stop scams in the decentralized finance ecosystem, and our approach can act as a whistleblower that identifies scam tokens at their early stages.

Typical discourses around the puzzle film ‐ a genre that typically eschews classic storytelling for more complex narrative techniques, such as entangled secondary/tertiary plotlines, and characters with mental or psychological instability ‐ often privilege the manipulation of the film’s temporality and narratology. However, in this article, I perform a close textual analysis of the mise en scène of Inception by Christopher Nolan (2010) and Eternal Sunshine of the Spotless Mind (2004) by Michel Gondry to demonstrate how these puzzle films privilege spatiality over time and plot to depict cognitive processes associated with mental and psychological instability, thereby bringing attention to an underrepresented attribute of the genre. I focus on the influence of surrealism on mise en scène, as surrealist art and cinema manipulate space to explore the psyche. I also draw on these films’ production history to show how the filmmakers, production crew and actors understood approaches to space as a cognitive process.

Introduction: Depression is a highly prevalent problem in adolescence, with great clinical and social relevance. Recent models of psychopathology in childhood and adolescence underscore that the relationships between stress, cognitive vulnerabilities, and depressive symptoms are bidirectional. In addition, according to cognitive therapy models, cognitive vulnerabilities are organized hierarchically, with deep schemas guiding more superficial cognitive processes such as rumination. The present study examines the longitudinal predictive relationships between two levels of cognitions (early maladaptive schemas and rumination), stressors, and depression. Method: A sample of 584 Spanish adolescents (262 girls; mean age = 15.99, SD = 1.10) completed measures of depression, stressors, rumination, and three early maladaptive schema domains (disconnection and rejection, impaired autonomy and other-directedness) over 4 intervals of 4 months. Path analysis was used to test the hypotheses of the study. Results: Disconnection and rejection domain systematically predicted an increase in depression, new stressors, and rumination over time. In addition, depressive symptoms predicted an increase of disconnection/rejection scores at all time points. Finally, from Time 2 on, stressors predicted an increase in all schema domains. Discussion: The outcomes suggest the importance of the disconnection and rejection schema domain. These results are important to understand the mechanisms underlying stress and depression in adolescents.

PurposeThe purpose of this article is to extend effectuation theory at the front end by building cognitive foundations for the effectual design process.Design/methodology/approachWe adopt an integrative conceptual approach drawing on design cognition theory to explain entrepreneurial cognition.FindingsWe find a significant gap in the entrepreneurial cognition literature with respect to effectuation processes. We thus integrate the Situated Function–Behavior–Structure framework from design theory to elaborate on the cognitive processes of effectuation, specifically with regard to the opportunity development process. This framework describes the cognitive subprocesses by which entrepreneurs means and ends are cyclically (re)formulated over time until a viable “opportunity” emerges, and the venture is formalized, or else, the entrepreneur abandons the venture and exits.”Practical implicationsUnravelling this entrepreneurial design process may facilitate more appropriate and effective design work by entrepreneurs, leading to more successful product designs. It also should facilitate the development of better design techniques and instruction.Originality/valueThis research contributes to new cognitive foundations for effectuation theory and entrepreneurial process research. It better explains how means are transformed into valuable goods over time through an iterative reconsideration of means-ends frameworks. This theoretical elaboration will expectedly facilitate additional research into the iterative cognitive processes of design and enable more formulaic design thinking.

Culture extends biology in that the setting of development shapes the traditions that individuals learn, and over time, traditions evolve as occasional variations are learned by others. In humans, interactions with others impact the development of cognitive processes, such as sustained attention, that shape how individuals learn as well as what they learn. Thus, learning itself is impacted by culture. Here, we explore how social partners might shape the development of psychological processes impacting learning a tradition. We studied bearded capuchin monkeys learning a traditional tool-using skill, cracking nuts using stone hammers. Young monkeys practice components of cracking nuts with stones for years before achieving proficiency. We examined the time course of young monkeys’ activity with nuts before, during, and following others’ cracking nuts. Results demonstrate that the onset of others’ cracking nuts immediately prompts young monkeys to start handling and percussing nuts, and they continue these activities while others are cracking. When others stop cracking nuts, young monkeys sustain the uncommon actions of percussing and striking nuts for shorter periods than the more common actions of handling nuts. We conclude that nut-cracking by adults can promote the development of sustained attention for the critical but less common actions that young monkeys must practice to learn this traditional skill. This work suggests that in nonhuman species, as in humans, socially specified settings of development impact learning processes as well as learning outcomes. Nonhumans, like humans, may be culturally variable learners.
