Through earnings announcements, conference calls, and other press releases, corporate executives have an opportunity to frame the narrative of financial disclosures. Numerous studies have shown that textual tone significantly influences stock returns, suggesting that through word choice, upper management may impact market reaction. In this study, we examine the influence of CEO personality traits on corporate disclosures by analyzing the tone of earnings announcements for a sample of Fortune 500 CEOs over nearly two decades. Our hypotheses are twofold: that qualitative (...) disclosures in firms with narcissistic leaders will be biased upward and the bias will moderate as CEOs becomes older. Our empirical results support these hypotheses and suggest that more narcissistic CEOs tend to reinforce their grandiose self-image by issuing more positive earnings announcements but this desire wanes with CEO age. We also find that the stock market response to the tone of the earnings announcement is less pronounced for more narcissistic CEOs, suggesting the market takes into account the bias in narcissistic CEO announcements.

This study explores the rationality behind firms’ decision to admit or deny their involvement in bribery when responding to confidential surveys conducted by international agencies. Specifically, we posit that firms’ reluctance to provide accurate information about their engagement in bribery is at least to some extent contingent on certain situational factors. In other words, we claim that this behavior is context dependent. The paper uses the notions provided by the theory of planned behavior to understand the way in which the (...) corruption of the legal environment, the intensity of market competition, and identification risk influence firms’ decision to lie about their involvement in bribery. To test these notions, we use databases from the fifth wave of the EBRD-World Bank Business Environment and Enterprise Performance Survey, country-level data from the Kauffman Foundation and macroeconomic information from the World Bank database. We run ordinary least squares with geographic region-clustered standard errors on data from 30 countries and 6122 individual firms during the period 2012–2013. Consistent with our expectations, the results indicate that firms operating within more corrupt legal environments, facing more competition, and bearing a higher risk of being identified are less likely to deny their involvement in bribery. We conclude that not all firms have the same incentives to lie about their participation in bribery, and therefore, identifying the drivers of this heterogeneity may help policymakers better assess the reliability of bribery information collected through confidential surveys.

Electricity is an indicator that shows the progress of a civilization; it is a product that has greatly changed the way we think about the world. Electricity price forecasting became a fundamental task in all countries due to the deregulation of the electricity market in the 1990s. This work examines the effectiveness of using multiple variables for price prediction given the large number of factors that could influence the price of the electricity market. The tests were carried out over four (...) periods using data from Spain and deep learning models. Two different attribute selection methods based on Pearson’s correlation coefficient have been used to improve the efficiency of the training process. The variables used as input to the different prediction models were chosen, considering those most commonly used previously in the literature. This study attempts to test whether using time series lags improves the non-use of lags. The results obtained have shown that lags improve the results compared to a previous work in which no lags were used. (shrink)

Claims that necessary and sufficient conditions are not converse relations are discussed, as well as the related claim that If A, then B is not equivalent to A only if B . The analysis of alleged counterexamples has shown, among other things, how necessary and sufficient conditions should be understood, especially in the case of causal conditions, and the importance of distinguishing sufficient-cause conditionals from necessary-cause conditionals. It is concluded that necessary and sufficient conditions, adequately interpreted, are converse relations in (...) all cases. (shrink)

This article aims to improve the knowledge on Generation Z as employees within workforce and in the workplace, as well as on the main thematic trends that drive the research on the topic. To this end, and using bibliometric techniques, a sample of 102 publications on this subject from Web of Science between 2009 and 2020 is analyzed. Research discusses the most published and most cited authors and journals to have a broad view of the context of the subject. Later, (...) through a longitudinal view, the study mainly focuses on analyzing the evolution of thematic clusters, to assess the progress of the themes, as well as the network around the principal motor cluster of each period. The obtained results suggest a hardly developed topic, which started to draw attention in 2018, while still having a wide margin for growth. The core of research on the topic has evolved around “Generation-Z” “generations,” “workplace,” “management” and “attitudes,” “leadership,” “career,” or “learning-teaching-education,” although a low keyword stability among periods was noted. There is a need for further development on a variety of aspects regarding this generation and the labor market, as the study shows a clear orientation toward management and generational diversity within the workplace.

"Tough, smart, superbly engaging, The Material Ghost is a terrific book." -- Edward W. Said In The Material Ghost , Gilberto Perez draws on his lifelong love of the movies as well as his work as a film scholar to write a lively, wide-ranging, penetrating study of films and filmmakers and the nature of the art form. For Perez, film is complex and richly contradictory, lifelike and dreamlike at once, a peculiar mix of reality and imagination. "The images on (...) the screen," he writes, "carry in them something of the world itself, something material, and yet something transposed, transformed into another world: the material ghost." "Dazzling... The sheer intelligence at work in these lucid pages is exhilarating." -- Alfred Guzzetti, Boston Book Review "A pleasure. Gilberto Perez is one of the smartest film critics writing anywhere." -- Jonathan Rosenbaum "Strikes an ideal balance between insightful analysis and graceful writing... A model of thoughtful criticism." -- David Sterritt, Christian Science Monitor "Brilliantly polemical in his critique of cynical reason ('the official philosophy of late capitalism'), no less passionate in defending the truth-value of cinema, Perez seems to be the clearest heir to the great humanist critic André Bazin." -- Sight & amp Sound "The chapters on Keaton and Renoir are stunning, full of perceptive remarks the chapter on Godard is a persuasive rehabilitation none of the chapters is without memorable insights." -- Michael Wood, London Review of Books "Gilberto Perez's ambitious, abundant, and cultivated book--the fruit of decades of thinking and teaching -- accompanies readers on a journey of discovery into the wonder of film." -- Stanley Cavell "Few books of film criticism in the past twenty-five years have been so enjoyable or instructive... [Perez] has excellent things to say about authorship, about documentaries, about popular genres, about cinematic point of view and narrative technique, about actors, and above all about camera style... He makes us want to look once more at the remarkable pictures he discusses." -- James Naremore, Cineaste. (shrink)

Throughout the 20th century, market capitalism was defended on parallel grounds. First, it promotes freedom by enabling individuals to exploit their own property and labor-power; second, it facilitates an efficient allocation and use of resources. Recently, however, both defenses have begun to unravel—as capitalism has moved into its “platform” phase. Today, the pursuit of allocative efficiency, bolstered by pervasive data surveillance, often undermines individual freedom rather than promoting it. And more fundamentally, the very idea that markets are necessary to achieve (...) allocative efficiency has come under strain. Even supposing, for argument’s sake, that the claim was true in the early 20th century when von Mises and Hayek pioneered it, advances in computing have rekindled the old “socialist calculation” debate. And this time around, markets—as information technology—are unlikely to have the upper hand. -/- All of this, we argue, raises an important set of governance questions regarding the political economy of the future. We focus on two: How much should our economic system prioritize freedom, and to what extent should it rely on markets? The arc of platform capitalism bends, increasingly, toward a system that neither prioritizes freedom nor relies on markets. And the dominant critical response, exemplified by Shoshana Zuboff’s work, has been to call for a restoration of market capitalism. Longer term, however, we believe it would be more productive to think about how “postmarket” economic arrangements might promote freedom—or better yet, autonomy—even more effectively than markets, and to determine the practical steps necessary to realize that possibility.

This article investigates three things: (1) what development might be, (2) how development and ethics might be related, and (3) what an ethics of development might look like. First, I show how if we move away from an essentialist metaphysics of being to a possibilist-functionalist metaphysics of becoming in our understanding of development, we can reconceptualize ethics as self-directed ontogeny. Thus, ethics turns out to be a part of development. Secondly, I sketch out the possibility of an ethics of development, (...) showing how it should be based on three desiderata: (1) sustainability, promoting the long-term existence of the maximum human and non-human biodiversity, (2) democracy, promoting human-human relationships that are bidirectional and, to the extent possible, non-imposing, and (3) non-ethnocentrism, promoting true modernity; a modernity not predicated on a non-existent abstract universality but on concrete syncretism. The ultimate aim of this ethics of development is the optimization of individual and collective subjectivity and agency across time. (shrink)

Cinema is commonly hailed as "the universal language," but how does it communicate so effortlessly across cultural and linguistic borders? Drawing on a lifetime's worth of viewing an reviewing, influential critic Gilberto Perez invokes a dizzying array of masters past and present includin Chaplin, Ford, Kiarostami, Eisenstein, Malick, Mizoguchi, Haneke, Hitchcock, and Godard--to explore the transaction between filmmaker and audience.

An extended examination of Libet's works led to a comprehensive reinterpretation of his results. According to this reinterpretation, the Minimum Train Duration of electrical brain stimulation should be considered as the time needed to create a brain stimulus efficient for producing conscious sensation and not as a basis for inferring the latency for conscious sensation of peripheral origin. Latency for conscious sensation with brain stimulation may occurafterthe Minimum Train Duration. Backward masking with cortical stimuli suggests a 125-300 ms minimum value (...) for the latency for conscious sensation of threshold skin stimuli. Backward enhancement is not suitable for inferring this latency. For determining temporal relations between stimuli that correspond to subjects' reports, theendof cerebral Minimum Train Duration should be used as reference, rather than its onset. Results of coupling peripheral and cortical stimuli are explained by a latency after the cortical Minimum Train Duration, having roughly the same duration as the latency for supraliminal skin stimuli. Results of coupling peripheral stimuli and stimuli to medial lemniscus (LM) are explained by a shorter LM latency and/or a longer peripheral latency. This interpretation suggests a 230 ms minimum value for the latency for conscious sensation of somatosensory near-threshold stimuli. The backward referral hypothesis, as formulated by Libet, should not be retained. Long readiness potentials preceding spontaneous conscious or nonconscious movements suggest that both kinds of movement are nonconsciously initiated. The validity of Libet's measures of W and M moments (Libet et al., 1983a) is questionable due to problems involving latencies, training, and introspective distinction of W and M. Veto of intended actions may be initially nonconscious but dependent on conscious awareness. (shrink)

A commentary is given on Trevena and Miller . The comparability of their experimental task and of the potential they recorded with those used and recorded by Libet, Gleason, Wright, and Pearl is questioned. An interpretation is given for the similarity of event-related potentials recorded when subjects decided to move and when they decided not to move.

This paper investigates whether 'even if A, B' is pragmatically polysemic, so that a nonconcessive conditional may have 'even if', and whether concessive conditionals, pragmatically defined, can fail to have 'even if' or a non-temporal 'still'. Different paraphrases are used to help elucidate pragmatic meanings. A theory of the pragmatic meanings of concessive and implicative conditionals is presented. The semantic meaning of 'even if' and the question of whether concessive conditionals imply the truth of their consequents are also discussed.

It is argued that contraposition is valid for a class of natural language conditionals, if some modifications are allowed to preserve the meaning of the original conditional. In many cases, implicit temporal indices must be considered, making a change in verb tense necessary. A suitable contrapositive for implicative counterfactual conditionals can also usually be found. In some cases, the addition of certain words is necessary to preserve meaning that is present in the original sentence and would be lost or changed (...) in the contrapositive without them. A distinction is made between adding new meaning and adding new words to preserve existing meaning. For concessive conditionals and relevance conditionals, however, no valid contrapositive can be found. They do not belong to the class of contraposable conditionals, which can be independently defined. Difficult cases are also discussed in which the contradictory of the consequent semantically entails the truth of the antecedent. In such cases the content of the antecedent is implicit in the meaning of the consequent. Contraposition becomes possible if what is implicit in the original consequent is made explicit in the contrapositive antecedent. (shrink)

In the Poetics of Aristotle there is a definition of the human being that perhaps has not yet been well considered in educational theory and practice. This definition calls into question a dynamism that according to Plato was unavoidable for an appropriate understanding of the educational process that turns a human being into a beautiful, good and just citizen: mimesis. The paper's intent is to reconsider the definition of the human being, centred on mimesis, presented by Aristotle in the Poetics (...) to demonstrate if, and how, it might establish new paradigms for human coexistence. Aristotle's anthropological statement is included in a much wider discourse concerning philosophy of art; but if isolated from the context, it is an essential definition of human beings that can be synthesised as follows: human beings are the mimetic animal par excellence, and their process of understanding has a fundamental connection with such excellence. Ignorance and/or negligence of how relevant mimesis might be in the educational process may have decisively contributed to separate human beings from this core aspect of their humanity and therefore produced painful consequences in human coexistence. As long as education does not pay attention to the pedagogical implications of the definition taken from the Poetics, how can human flourishing be safeguarded? I argue that recognition of the centrality of mimesis in the educational process allows human edification to proceed devoid of ideological basis, be it secular or confessional; and overcomes the risk of relativism. Mimesis, formerly recognised by Plato as a link between what is expressed and what really is, is masterfully reinterpreted by Aristotle. Aristotle recognised its positive pedagogic value in the Poetics, and nowadays we can recognise how it offers existential dynamics that restore the vital human relationship between self and other. The sense of this proposal lies in giving mimesis the role it deserves in education, by raising the significance of how coexistence might benefit from a vast human dimension, capable of recognising our humanity beyond our rational capacity.

An examination of conditionals in di¤erent languages leads to a distinction of three types of conditionals instead of the usual two (indicative and subjunctive). The three types can be explained by the degree of acceptance or as-if acceptance of the truth of the antecedent. The labels subjunctive and indicative are shown to be inadequate. So-called indicative conditionals comprise two classes, the very frequent uncertain-fact conditionals and the quite rare accepted-fact conditionals. Uncertain-fact conditionals may have a time shift in contemporary English (...) and the future subjunctive in Portuguese (though not all of them do). Moreover, paraphrases of if with in case or supposing are usually possible with approximately the same meaning. Accepted-fact conditionals never have these features. (shrink)

1. Introduction The readiness potential was found to precede voluntary acts by about half a second or more (Kornhuber & Deecke, 1965). Kornhuber (1984) discussed the readiness potential in terms of volition, arguing that it is not the manifestation of an attentional processes. Libet discussed it in relation to consciousness and to free will (Libet et al. 1983a; 1983b; Libet, 1985, 1992, 1993). Libet asked the following questions. Are voluntary acts initiated by a conscious decision to act? Are the physiological (...) facts compatible with the belief that free will determines our voluntary acts? What is the role of consciousness in voluntary action? In this paper I will discuss these questions and the answers that Libet gave to them. (shrink)

Television commercials are often thought of as bothersome multimedia artefacts that by their very existence spoil our viewing pleasure at regular intervals. Not only that, but they seem to have the habit of ordering us around. This aspect of TV ads has often been commented on by experts and laypersons alike. Therefore, we decided to tackle this issue and look at the prototypical expression of directives, that is, imperatives in voice-overs in television commercials. To this end we have carried out (...) an empirical analysis of imperatives in voice-overs in the MATVA corpus which contains transcriptions of nearly 800 voice-overs in British TV ads recorded on six days during 2009, 2010 and 2011. We provide an exhaustive quantitative and qualitative profile of imperatives in contemporary TV advertising. This includes information on the distribution of imperatives, the most common verbs in imperative clauses, and their discourse function. We are also able to show conclusively that the directive force of imperatives in TV ads is more akin to advice or recommendation than commands, and explain from a discourse-pragmatic perspective why this is so.

Assuming that linguistic representation has been studied only by linguists using grammaticality judgments, Branigan & Pickering present structural priming as a novel alternative. We show that their assumptions are incorrect for cognitive-functional linguistics, exposing converging perspectives on form/meaning pairings between generativists and cognitive-functional linguists that we hope will spark the cross-disciplinary discussion necessary to produce a cognitively plausible model of linguistic representation.

The analysis is restricted to the architectural aspect. It puts in evidence a dialectical procedure which makes the gnoseological importance of the verb to look stand out clearly. The pharisee's knowledge is based on religious convictions ; that of the blind man on his experience.

The generation of synthetic data is becoming a fundamental task in the daily life of any organization due to the new protection data laws that are emerging. Because of the rise in the use of Artificial Intelligence, one of the most recent proposals to address this problem is the use of Generative Adversarial Networks. These types of networks have demonstrated a great capacity to create synthetic data with very good performance. The goal of synthetic data generation is to create data (...) that will perform similarly to the original dataset for many analysis tasks, such as classification. The problem of GANs is that in a classification problem, GANs do not take class labels into account when generating new data, it is treated as any other attribute. This research work has focused on the creation of new synthetic data from datasets with different characteristics with a Conditional Generative Adversarial Network. CGANs are an extension of GANs where the class label is taken into account when the new data is generated. The performance of our results has been measured in two different ways: firstly, by comparing the results obtained with classification algorithms, both in the original datasets and in the data generated; secondly, by checking that the correlation between the original data and those generated is minimal.

Libet's (2000) arguments in defense of his interpretation of his experimental results are insufficient. The claims of my critical review (Gomes, 2008) do not suffer with his new statements.

A commentary on articles by Klein, Pockett, and Trevena and Miller, in this issue, is given. Average shift in the point of subjective equality , calculated by Klein on Libet's data, and corresponding change in mean shift, calculated by Libet et al. , may be “corrected,” taking as a reference point the end of the minimum train duration. Values obtained, if significant, indicate a latency for conscious sensation of the skin stimulus of at least 230 ms. Pockett's main conclusions are (...) favored, but her explanation of peripheral–lemniscal couplings is found to be unconvincing. Trevena and Miller's article unsuccessfully tries to rescue a dualist interactionist view. Libet's method of timing intentions is thoroughly criticized. (shrink)

At this time when the development of synthetic biology and artificial intelligence are changing the world around us, philosophers and scientists, first of all, must converge to analyze the present and predict the ethical-social consequences and biological dangers associated with new “living entities” that are not the result of the natural evolutionary process. As synthetic/artificial life forms (xenobots, robots, transgenic organisms, etc.) become more and more abundant and sophisticated, it seems first of all necessary to bring some order to all (...) this new biodiversity, establishing what is alive and what is not, and analyzing the consequences of this incessant creative activity. Here I intend to organize all these human-made entities and clarify their status as living beings or artificial elements, leaving the door open to an uncertain future in which we will be able to see how “the artificial” and “the natural” could merge to originate something different from everything known. Accordingly, I propose the creation of a new domain, Lithbea, which includes all synthetic and artificial entities within a new kingdom called Humade (derived from human-made). I have also included viruses in a new realm, the Viral kingdom, because they were excluded from the classical three-domain tree of life despite playing a fundamental role in the evolution of biodiversity on Earth. Finally, I make a brief comment on the unpredictability of the unknown, the implications of this new landscape of biodiversity, and the uncertain future of all these advances. (shrink)

Assisted Reproductive Technologies, as a solution to the issues of human infertility, have been developed since the mid-twentieth century. The development of these techniques, their progress and results have occurred simultaneously with two events related to ART: the establishment of new rights that have contributed to their endorsement, and the birth of bioethics that have allowed the recognition of their limits. The cultural change due to the coming of ART is characterized by three topics that are discussed in this article (...) and which are all included in the so-called gender ideology: the concept of woman and the control of her body, kinship and parentage, and the idea of autonomy. Some considerations on these topics are presented as well as some alternatives to ART, which include learning to redirect their work based on criteria pointed out by bioethical reflection. Such criteria reveal the profound meaning of preserving the dignity of every single person within a true human framework. (shrink)

Em sua última obra, As Duas Fontes da Moral e da Religião, Henri Bergson investiga as origens, o desenvolvimento e a manutenção da sociedade humana por meio da distinção entre a sociedade fechada, baseada nos instintos primitivos de conservação da vida, e a sociedade aberta, fundada sobre a aspiração que impulsiona o homem à construção de uma vida em sociedade mais harmoniosa. Segundo o autor, os ideais democráticos são frutos da abertura de que as sociedades necessitam para seu progresso, o (...) qual, aos poucos, abrandaria a pressão das exigências impostas pela natureza para a conservação da vida em sociedade e possibilitaria aos homens conviverem mais livremente e mais afetuosamente com vistas a uma sociedade mais justa e sem tantos conflitos e mortes. Contudo, como escapar às determinações que a natureza impôs para que a vida em sociedade se mantivesse e conseguir que os homens se abram a outro tipo de vivência em conjunto? É esta a questão que o presente artigo procura investigar. Palavras-chave: Bergson, moral, política, mística. (shrink)

Traditionally, political philosophers and theorists (from Plato and Aristotle to Montesquieu) not only systematically distinguished a greater number of political regimes than we are accustomed to distinguish today (identifying several varieties of democracy and non-democracy, according to several normative criteria) but also used these distinctions for specifically evaluative purposes: distinctions among political regimes corresponded to the degree to which a political regime facilitated important values (e.g., the common good, the good life, freedom, etc.). Questions of evaluation often took priority over (...) questions of justification. Contemporary political theory, by contrast, with some exceptions, has mostly operated within the restricted distinction between (liberal) democratic and non-democratic regimes, and has failed to attend to the morally significant differences among "imperfect" or "less justified" political regimes. Questions of justification have mostly taken priority over questions of evaluation. In this paper, I explore the possibilities for constructing an evaluative theory of imperfect (or not fully justified) political regimes. I argue that a political regime is a system for the division of the labor of political decisionmaking that can (and has historically been) evaluated from three different perspectives: the perspective of the decisions made through it, the perspective of the interests promoted and protected through it, and the perspective of its stability in regards to the kinds of characters it fosters and through which it is sustained. Each of these perspectives provides their own criteria for evaluation: the idea of a well-organized regime for the "decisions" perspective, the idea of a public-goods producing regime for the "interests" perspective, and the idea of a "resilient" regime for the stability perspective. Nevertheless, I also show that these criteria are not necessarily congruent with one another, and that a fully justified regime need not be ideal along any of these dimensions. I suggest that this problem is unavoidable insofar as political regimes facilitate the pursuit of more than one central value. (shrink)
