False Identity Detection Using Complex Sentences

The use of faked identities is a current issue for both physical and online security. In this paper, we test the differences between subjects who report their true identity and the ones who give fake identity responding to control, simple, and complex questions. Asking complex questions is a new procedure for increasing liars' cognitive load, which is presented in this paper for the first time. The experiment consisted in an identity verification task, during which response time and errors were collected. Twenty participants were instructed to lie about their identity, whereas the other 20 were asked to respond truthfully. Different machine learning (ML) models were trained, reaching an accuracy level around 90-95% in distinguishing liars from truth tellers based on error rate and response time. Then, to evaluate the generalization and replicability of these models, a new sample of 10 participants were tested and classified, obtaining an accuracy between 80 and 90%. In short, results indicate that liars may be efficiently distinguished from truth tellers on the basis of their response times and errors to complex questions, with an adequate generalization accuracy of the classification models

Filtragem adaptativa para a estimação da freqüência em sistemas elétricos de potência

Esta pesquisa apresenta um método para a estimação da freqüência em sistemas elétricos de potência utilizando filtros adaptativos baseados no método dos mínimos quadrados (MMQ). A análise do sistema de potência é realizada através da conversão das tensões trifásicas em um sinal complexo pela aplicação da transformada α β, sendo este direcionado ao algoritmo de filtragem adaptativa. As simulações computacionais, assim como a modelagem dos equipamentos, foram realizadas utilizando-se do software ATP (Alternative Transients Program). Este teve por objetivo, gerar dados das mais diversas e distintas situações para a verificação e análise da metodologia proposta, em comparação a resultados obtidos de um determinado relé comercial, habilitado à supervisão da freqüência do sistema.This research presents a method for frequency estimation in power system using adaptive filter based on the Least Mean Square algorithm (LMS). In power system analysis, the three-phase voltages are converted to a complex signal with the application of α β-transform whose complex form was submitted to the algorithm of adaptive filtering. The computational simulations were accomplished using the software ATP. This utilization had as objective to generate data for the most severe and different situations for the verification and analysis of the proposed methodology.

AI, robot, and consciousness : a brief history in cinema

This paper explores a brief history of science fiction cinema, and the relatives themes presented in some significative films: e.g. "The Bicentennial Man, Ex Machina", and "Her". In the first paragraph I will investigate about the early portrayals of AI in cinema. The following paragraphs explore the development of consciousness in artificial beings and the complex relationship between humans and AI. I will show how Andrew Martin and Ava develop a consciousness with opposite consequences. Instead, Theodore is the perfect example of human weakness. Through compelling narratives, the cited films contemplate nature of consciousness, and the moral responsibilities associated with AI development. By inviting audiences to reflect about characters navigating the interface between humanity and technology, these films illuminate the evolving landscape of human relationships and the countless conceptions of AI

Lie detection in the future: the online lie detection via human-computer interaction

Half the people in the Planet Earth are now on internet, surfing the web, keeping connection with the outside world, using online services and interacting in social networks. However, the spread of internet is going hand in hand with the growing malicious use of it. Creating fake social network profiles, wide spreading fake news, posting fake reviews, identity theft to perpetuate online financial frauds are only few examples. To face these problems, all the big internet compa-nies, like Google and Facebook, are now taking the direction towards the online lie detection re-search. The present work is a contribution to online deception detection through the study of com-puter-user interaction. After a brief review of the current lie detection methods, focusing on their advantages and disadvantages for online application, a series of proof of concept experiments are reported. Experiments were conducted measuring indices deriving from three different tools of human-computer interaction: reaction times on keyboard, keystroke dynamics and mouse dynam-ics. Two strategies were used to increase liars’ cognitive load and facilitate the observation of distinctive features of deception: unexpected questions and complex questions. Experiments fo-cused on the deception about identity, as it is a very hot issue and represents a current challenge for companies that provide online services. Participants were asked to respond lying or truth tell-ing to questions that appeared on the computer screen, typing the response, clicking on it with the mouse or pressing one of two alternative keys on keyboard. Data collected from liars and truth-tellers’ responses were analyzed and used to train machine learning classification models. Classi-fication accuracies in distinguishing liars from truth-tellers ranged from 80% to 95%, depending on the deceptive task. Results have proved that it is possible to spot liars analyzing their interac-tion with the computer during the act of lie. In particular, we demonstrated that keystroke dynam-ics is a very promising tool for covert lie detection and it is easily integrable with the online exist-ing applications. Moreover, we confirmed that the cognitive complexity of the deceptive task in-creases the possibility to detect deception

Pathological existence and freedom of technology : the drama of freedom in Günther Anders' writings

In this paper I try to show the relationship between the concept of freedom and the concept of technique as developed by Günther Anders. I will argue that in Anders' writings there is a specific conception of freedom. The underlying idea is that freedom represents a sort of pathology. Humans live as strangers in the world, lacking in an a priori endowment that, for this very reason, they have to realize. Man acts as a producer of useful objects for his own survival, and in this sense, there is a freedom to use technical capacity. Man is free to use technology to live in the world and without technology man couldn't survive. Thus, with his own hands man manipulates the world, the production of which is led by a series of steps from a lack to technology, from abstraction to realization. The use of technology, however, according to Anders, is dramatic because there is no freedom, except to be free to use technology

The Pledge, the Turn, the Prestige: The Border Between Magic and Technology as Practices

In this paper I will try to show how magic and technology might be associated taking both into account as a cultural expression of contemporary society. I will argue that technology penetrates magic, creating a specific dynamic which raises ethical dilemmas. The underlying idea, following a long tradition of thought, is that technology represents a kind of "second human nature." As Arnold Gehlen claims, the technical attitude (Technik) compensates for the structural deficiency of humans, allowing them a gradual opening to the world. But magic is also an expression of this attitude, insofar as it tends to mimic natural mechanisms. Magic expresses itself with instructions, rules, and purposes, as much as technology does. Precisely for this reason magic also involves the same rationality typical of the developmental mode of technology, sharing the same objective. I will argue that Christopher Nolan's movie The Prestige (2006) shows an example of technological integration inside magic itself, highlighting two orders of problems: one ethical and the other intrinsic to the magical act and its nature

The Relationship between Drug Consumption and Dating App Use: Results from an Italian Survey

To date, the literature regarding the relationship between drug consumption and dating app use is still very scant and inconclusive. The present study was thus aimed at investigating the association between drug consumption and dating app use in the general population. A total of 1278 Italian respondents completed an online ad hoc questionnaire assessing drug consumption (cannabis versus other illicit drugs), dating app use, the primary motive for installing dating apps, and demographics. Multiple logistic regression analyses were run to investigate the role of demographics and dating app use on drug consumption. Being single predicted cannabis use. Using dating apps accounted for higher odds of cannabis use; however, people who intensely used the apps were less likely to consume marijuana. Conversely, dating app use was not associated with the consumption of other drugs. This study suggests the presence of common underlying factors between dating app use and cannabis use, and it highlights the mediating role of the intensity of app use. Conversely, the study suggests that dating app use and the use of other drugs are quite independent behaviors

The Association between Dating Apps and Alcohol Consumption in an Italian Sample of Active Users, Former Users, and Non-Users

To date, the relationship between alcohol use and dating app use has been investigated mostly in conjunction with sexual activities and in homosexual men. For this reason, the aim of this study was to explore the association between dating app use and alcohol consumption among the general population. A cross-sectional study was conducted including app users, non-users, and former users: 1278 respondents completed an online ad hoc questionnaire assessing dating app use, motivations for installing dating apps, alcohol use, and demographics. Multiple logistic regression analysis was run to investigate the association between dating app use, demographic features, and alcohol consumption. Whereas educational level, age, and gender significantly contributed to the regular consumption of alcohol, dating app use did not account for a significant amount of variance between regular and not regular drinkers. However, people who installed and used dating apps with the motivation of searching for sexual partners were more likely to be regular drinkers. Among the active users, heavy app users were less likely to drink regularly. The study indicates that underlying factors (sexual aspects, motives for using the apps) and the intensity of using the apps may mediate the relationship between dating app use and alcohol use
