We present a framework for verifying systems composed of heterogeneous reasoning agents, in which each agent may have differing knowledge and inferential capabilities, and where the resources each agent is prepared to commit to a goal (time, memory and communication bandwidth) are bounded. The framework allows us to investigate, for example, whether a goal can be achieved if a particular agent, perhaps possessing key information or inferential capabilities, is unable (or unwilling) to contribute more than a given portion of its (...) available computational resources or bandwidth to the problem. We present a novel temporal epistemic logic, BMCL-CTL , which allows us to describe a set of reasoning agents with bounds on time, memory and the number of messages they can exchange. The bounds on memory and communication are expressed as axioms in the logic. As an example, we show how to axiomatise a system of agents which reason using resolution and prove that the resulting logic is sound and complete. We then show how to encode a simple system of reasoning agents specified in BMCL-CTL in the description language of the Mocha model checker (Alur et al., Proceedings of the tenth international conference on computer-aided verification (CAV) , 1998), and verify that the agents can achieve a goal only if they are prepared to commit certain time, memory and communication resources.

The present research was guided by the important need for a diversion from an economistic to a humanistic management perspective of sustainability. It concentrates on the current importance of digital strategic communication, particularly regarding the concept of corporate sustainability in the context of the conflict arena of the oil industry. The focus is on the comparison of the persuasive effectiveness of the framings of corporate versus activist NGO website communications and their impacts on the perception of the triple pillars of (...) sustainability and, corporate greenwashing with respect to a proposed bituminous oil pipeline in Canada. The results of these pro and con messages were analyzed within the Elaboration Likelihood Model demonstrating a “non expert” peripheral route to a positive persuasion from exposure to the corporate communication versus an “expert” central route to a negative persuasion from the activist NGO communication. Subsequent exposure to the opposite website communication further emphasized the predominance of a negative persuasion based on both groups now being motivated as “expert” viewers of these strategic communications, leading to an important perception of greenwashing by participants resulting from vague claims, visual and linguistic contents of the corporate communication versus the mainly verifiable factual ones in that of the activist NGO.

The absence of a clear distinction between notions of the individual and the social or general must, in fact, raise particularly strong reservations about any critical method as preoccupied as French structuralism is with comparisons between art and natural language. To be sure, this preoccupation has led to the isolation of many suggestive likenesses and differences between music and language. Among the likenesses, for example, is the assertion that both language and music constitute semiotic media within which the same techniques (...) for verifying competence and correctness of usage can be applied. Lévi-Strauss is insistent that musical as well as linguistic usage must be subject to verification through reference to some sort of "double articulation," or what will more generally be called here "dual structure," that is, through some method whereby, in effect, speakers and listeners can test each other's competence by altering the relationship between a more general and a more particularized level of a system and observing each other's responses.1 Nattiez essentially rejects this method of verifying competence, but he proposes two others which have analogues in the linguistic theory, respectively, of Zellig Harris and of Noam Chomsky ; interestingly these methods, which appear to be more "modern" than Lévi-Strauss', rely far more heavily on faith in fundamentally unexplainable judgments by single individuals, especially by individual "experts." · 1. Lévi-Strauss' somewhat obscure account of double articulation in Raw and Cooked differs from standard accounts such as André Martinet's and John Lyons' in Noam Chomsky , pp. 19-20. Lévi-Strauss appears to include both phonemes and morphemes in the code level, whereas it is more usual to oppose to the phonemic or sound level a level of meaning which is both semantic and morphemic.

With the increasing popularity of the Internet, email marketing has become a convenient and dynamic mode of communication that enables business organizations and personal sellers to promote their products or services at a much lower cost and with a potentially more global reach. This article aims to examine the impact of new media on the encoding of persuasive messages in sales emails as a channel of direct marketing, and the extent to which the use of new media influences the (...) overall interactional or social strategy of credibility enhancement and persuasion in the context of sales promotion. A genre analysis based on a modified move scheme proposed in this study was conducted on 160 sales letters randomly selected from a database of 10,972 sales letters collected from 36 categories of recipients in Hong Kong over a six-month period. Similarities and differences in discourse structures were found across the two corpora, and discussions were made with reference to a conceptual framework titled the Lingual-Belief Interaction Model proposed by the author. The model addresses the role of text, context, and interface in sales email study on the one hand, and the interplay of belief, interaction, and language in persuasive communication on the other. In-depth interviews were conducted with 16 specialist and corporate informants in the field of sales promotion communication to verify the results of analysis. (shrink)

We study a situation where a decision maker relies on the report of a self-interested and informed expert prior to decide whether to undertake a certain project. An important feature in this interaction is that, depending on the collected information, the two agents have potentially conflicting preferences. Information contained in the report is partially verifiable in the sense that the expert can suppress favorable information sustaining the project but he cannot exaggerate it. Our results show that this setting favors (...) the agent which is the less eager to undertake the project in that he always succeeds to induce his most preferred action. (shrink)

The message is that physics has an „outward bound” of scientific inquiry in the field of cosmology. I present it in the historical development. Physics and astronomy, developing since the seventeenth century, inherited from the early Greek philosophers the conception that the Universe as a whole is invariable. In nineteenth century this conception in conjunction with the conception of eternity of the Universe gave rise to contradictions with other laws of physics indicating that cosmology is not a branch of physics (...) since the notion of the Universe is not a physical one. Cosmology returned to physics as its important branch due to the advent of general relativity theory and the discovery of the cosmic microwave background radiation. Modern cosmology generates fundamental problems creating real limits to inquiries in physics viewed as an empirical science. The very notion of the Universe shows that the scientific method reaches there limits of its applicability. Does „to exist” mean „to be observed by someone”? Should the definition of the Universe be based on a current physical theory, e.g. on Einstein’s general relativity, giving rise to a kind of mathematical instability? Is the fashionable concept of the „multiverse” a physical one or is a purely metaphysical notion in a scientific disguise? If the Universe is unique, is it meaningful to describe it in the framework of physics, which by its method always assumes that the number of objects it describes, is unlimited? Apart from these permanent philosophical problems there are concrete urgent problems generated by cosmology: the nature of dark matter and dark energy. These two species of „substance” appear only in cosmology and do not fit the laboratory physics; contrary to the three centuries long tradition of modern science, now cosmology inspires physics in a troublesome way. A separate class of limits to physics is generated by the theorem in general relativity that the Universe emerged from an initial curvature singularity of the spacetime. At the singularity the whole scientific inquiry breaks down. Cosmology of the very early Universe suggests that in its evolution two specific epochs took place, that of quantum gravity and an inflationary epoch. The underlying them two physical theories are incomplete and seem to be inherently untestable. Furthermore, the experimentally verifiable physics cannot explain the origin of the initial conditions determining properties of the Universe which emerged from the singularity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 38.1 (2004) 1-11 [Access article in PDF] The Artistic Failure of Crime and Punishment Crime and Punishment Hugh Mercer Curtler This essay begins by noting some fundamental differences between poets, in the broad sense of that term, and philosophers, or those who reflect discursively. It then moves to an examination of the epilogue to Crime and Punishment where Dostoevsky abandons poetry in order to (...) make a philosophical statement about human freedom. 1 Indeed, it can be said that much of Dostoevsky's mature writing was a battle between the man's urge to make pronouncements and the poet's need to control those urges. Fortunately, the poet nearly always won; at times he did not. This can be seen in the case of Crime and Punishment where Dostoevsky, the man, insisted on formulating an idea, specifically, the "idea of freedom." This statement marks the artistic failure of the novel, a concession on the part of the poet to the man. The tension in this novel, and indeed in many novels, is an important focalpoint in the teaching of great literature, because readers of fiction frequently forget that great novels are also great works of art. In this regard, despite the fact that he is an extremely careful reader of Dostoevsky's books, the psychologist/critic René Girard misses in his quest to find hidden messages — precisely what makes Dostoevsky a great artist who writes novels. 2 What this means to teachers of exceptional literature is that we must be attuned not only to what the author says, but also to the way in which he or she says it. In his writings about Dostoevsky, Girard is not terribly interested in what the poet has to say; he is interested in the way the man works out a particular psychological problem. Consequently, like many other critics, Girardglosses over the fundamental difference between the body of Crime and Punishment and its epilogue. Poetry and Philosophy Contrasted There is no truth in art, strictly speaking. If the term "true" has any application whatever to the world of art, it means "honest," or "true to life" [End Page 1] (which, as Kafka has shown, is not terribly important). Moreover, "true" may refer to the work's adherence to rules of craft, its internal harmony and coherence as a distinctive work of the human imagination. What one finds in poetry or linguistic art is a hodgepodge of images, thought fragments, figures, episodes, incidents, hints, and bits and pieces, and (if the poet is a good one) stunning insights. Poetry is, like all art, ineluctably ambiguous. It does not have a "message"; it has many messages. This is precisely why we need art and what makes art different from philosophy in its struggle to eliminate ambiguity. We will not find truth, in the form of knowledge or understanding, among the poet's wares, since knowledge, systematized and rendered coherent by means of the laws of thought, is the charge of the philosopher and his modern stepchildren.What this means is that those who approach novels intent upon finding a message run the risk of hammering poetry into a sheet by reducing it to philosophy. But novels, if they are any good, are not philosophical treatises, and this sort of reduction glosses over fundamental differences of scope and method.In an age that collapses distinctions lazily in order to reduce complex matters to simple terms, we must insist upon the fundamental differences between poets and philosophers. The domain of the philosopher is that of the concept or the principle, of ideas as objects of reflection. Philosophers deal in discursive thought as they seek logical coherence and conceptual clarity. The poet may employ ideas, but he uses them and embodies them imagistically: he does not try to develop them or verify them. 3 The philosopher's domain is unfriendly and unfamiliar to the poet. The law of contradiction reigns supreme there, and this law is anathema to the poet with his love of paradox.The poem presents images that must be apprehended in... (shrink)

To apply the notion of language to the animal world is admissible only at the price of misusing terms. We know that it has been impossible until now to prove that animals enjoy, even in a rudimentary form, a means of expression endowed with the characteristics and functions of human speech. All serious observations made of animal communities, all attempts to establish or verify, by means of various technical devices, any form of speech comparable to that of man have failed. (...) It does not seem that animals which emit certain kinds of calls are thereby displaying any behaviour from which we may infer that they are conveying ‘spoken’ messages to one another. The fundamental conditions for a strictly linguistic communication seem to be lacking even in the higher animal world. (shrink)

The dramatic increase of meat production in the last decades has proven to be one of the most impacting causes of negative environmental outcomes (e.g., increase of greenhouse emissions, pollution of land and water, and biodiversity loss). In two studies, we aimed to verify the role of key socio-psychological dimensions on meat intake. Study 1 (N= 198) tested the predictive power of an extended version of the Value-Belief-Norm (VBN) model on individual food choices in an online supermarket simulation. In an (...) online survey, participants were directed to a virtual shop and asked to buy food within a set amount of money. Subsequently, they completed measures of behavioral intention, the VBN constructs (values, general pro-environmental beliefs, awareness of consequences, ascription of responsibility, and personal norm), and social norms (injunctive and descriptive). The outcome variable was operationalized in terms of percentage of expenses dedicated to meat and processed meat items, which provided a more robust behavioral measure than the common self-reported ones. Results confirmed the VBN sequential path, showing direct effects of biospheric values and descriptive norm on personal norm. Furthermore, a proof of validity for the new behavioral measure was provided (medium-sized correlation with behavioral intention). Study 2 (N= 218) aimed at verifying whether the meat consumption could be also motivated by a health concern, reflecting individual (cost/benefit) considerations, besides pro-environmental drivers. Results showed the direct impact of health concern and confirmed the indirect role of biospheric values and descriptive norm (viapersonal norm) on meat intake. This evidence would suggest the use of multiple-frame messages, highlighting both pro-environmental and health consequences, for meat consumption reduction. Nevertheless, the different implications of moral (e.g., environmental concern) vs. non-moral motivators (e.g., health concern) for reducing meat intake need to be stressed: indeed, the first drivers are more central for self-identity and for engaging in environmental citizenship behaviors.

As false information may spread rapidly on social media, a profound understanding of how it can be debunked is required. This study offers empirical insights into the development of rumors after they are debunked, the various user groups who are involved in the process, and their network structures. As crisis situations are highly sensitive to the spread of rumors, Twitter posts from during the 2017 G20 summit are examined. Tweets regarding five rumors that were debunked during this event were manually (...) coded into the following categories: rumor, debunking message, uncertainty about rumor, uncertainty about debunking message, and others. Our findings show that rumors which are debunked early and vehemently by official sources are the most likely to be stopped. When individuals participate in the process, they typically do so by sharing uncommented media content, as opposed to contributing user-generated content. Depending on the conditions in which a rumor arises, different network structures can be found. Since some rumors are easier for individuals to verify than others, our results have implications for the priorities of journalists and official sources. (shrink)

Dominic Wilkinson suggests that one of Schubert’s songs has relevance for neonatologists today. In the song, Schubert suggests that death sometimes comes as a friend. Wilkinson ponders whether the song has a message for doctors and parents, who sometimes struggle to figure out whether death is an enemy or a friend to a dying baby. Wilkinson reflects on the case of baby ‘Hal’, who was born with serious cardiomyopathy. Hal’s parents and doctors disagree about whether to withdraw life-support. Through his (...) recreations of their discussions, Wilkinson shows how hard it is to confront—and maybe even welcome—death for a child. While adults often frame their own decision to forego life-sustaining treatment with thoughts that they have lived a good life, death in childhood can seem unfair because it robs the child of their opportunity to live a good or completed life. Much as we try, we cannot really imagine what a critically ill neonate experiences or desires. We have very little insight into Hal’s interests or subjective experience. Without direct access to the child’s experience, it is impossible to know whether, like an adult, a child would choose to allow death to occur. We cannot verify the claim that the child’s death was good in the sense that it was good for them. Wilkinson proposes that a prolonged dying process …. (shrink)

COVID-19 is an acute respiratory illness with higher mortality in older adults. This condition is spread person-to-person through close contact, and among policies employed to decrease transmission are the improvement of hygiene habits and physical distancing. Although social distancing has been recognized as the best way to prevent the transmission, there are concerns that it may promote increased depression symptoms risk and anxiety, mainly in older adults. This cross-sectional study aimed to verify self-concept of social distancing in adults compared to (...) older adults. All participants, over 18 years and residents of São Paulo state, were invited to join this research study by a message application and answered an interdisciplinary questionnaire during the period from May 23 to June 23, 2020. The questions were divided into the following aspects: sociodemographic data, financial conditions, routine-related perception, perception of health, physical and emotional state, and eating habits. The younger adult group was composed of 139 participants, with a mean age of 43.15 years, and the older adult group was composed of 437 participants with a mean age of 67.59 years of both sex. Changes in routine during the period of social distance were reported by 95% of adults and 96.8% of older adults, but adults indicated more significant alterations in routine. Although there was no difference between groups for several aspects, adults revealed greater alterations in sleep quality, evacuation frequency, and more difficulty to perform daily activities at home. Further studies are necessary to follow up the impacts of social distancing among adults and older adults in different socioeconomic contexts to better understand the long-term alterations and the necessity of interventions.

The paper describes an innovative structured workshop methodology in garden-based-learning called “Nature in Your Face” aimed at provoking a change in citizens behavior and engagement as a consequence of the emotional activation in response to disruptive artistic messages. The methodology challenges the assumption that the change needed to meet the carbon targets can be reached with incremental, non-invasive behavior engineering techniques such as nudging or gamification. Instead, it explores the potential of disruptive communication to push citizens out of their (...) comfort zones and into creative modes of re-creating futures. This is done by confronting us with consequences of consumption by means of art and eco-visualizations. The aim being to achieve awareness, mental flexibility, and spurring debate. Thus, we invite them to react – and act upon these reactions by communicating their feelings or thoughts. This is used as an entrance point for broader and/or deeper engagement in a structured three-step methodology; Framing: A disruptive element is introduced into the local environment. This triggers an emotional reaction, which then is taken up in a process of framing the problem and working with solutions. Twisting: in a guided process, the initial energy from the emotional confrontation is twisted into a creative exploration of innovative solutions, from the perspective of the children. Using: The last stage is using the developed solutions in the local social system. The methodology is being applied in cooperation with a primary school, and is iteratively adjusted and evaluated in a formative, action-research based approach scenario. NiYF is to stimulate societal engagement through deliberately confronting stakeholders with unexpected and potentially upsetting appearances of nature, climate effects, or carbon-neutral lifestyle scenarios. We have verified the practical usefulness and potential of the methodology and found that NiYF triggers societal engagement and transition, negotiating responsibilities and unlocking action potentials. We also found that eco-anxiety, denial, self-efficacy and cognitive dissonance form children’s understanding of plastic. The project marks a paradigm shift from creating knowledge to using knowledge to create action, and a focus on learning from evaluating and adapting the approach in the field. (shrink)

We propose a triple test to evaluate the usefulness of behavioral economics models for public health policy. Test 1 is whether the model provides reasonably new insights. Test 2 is on whether these have been properly applied to policy settings. Test 3 is whether they are corroborated by evidence. We exemplify by considering the cases of social interactions models, self-control models and, in relation to health message framing, prospect theory. Out of these sets of models, only a correctly applied prospect (...) theory fully passes the tests at present. Specifically, in broad agreement with the evidence, a gain frame has positive implications for welfare encourages disease prevention activity, though this does not apply if the perceived probability of the bad health outcome is large enough. We see our tests as being useful to identify how much health policy weight policy makers should assign to specific behavioral economic models; they are also useful to verify what next steps would be most useful in further research.

The beginning of the 21st century is the time of a new challenge for the Polish nation. Standing on the threshold of a new century, it has also stood on the ‘threshold’ of the united Europe. Culture is a binder thanks to which it is possible to discover and to maintain peoples’ identity and the bonds connecting individual members of the nation. The multitude of nations is a variety which makes Europe not a monolith in relation to culture; instead, it (...) constitutes a mosaic of different cultures and philosophies of life. The Church does not try to identify with any of the culture patterns, but it seeks its place among the diversity of their forms. However, one can talk about the development of a Christian culture model resulting from the faith and the presence of the evangelical message in the whole of the Christians’ life. In the survey concerning Poland’s accession to the European Union, Polish people have expressed their hopes and fears connected with the process of integration. As many as 11% of the people surveyed expressed their anxiety related to the adverse effect upon culture and customs. The Church in its social instruction continuously emphasizes the necessity of maintaining one’s own cultural identity by particular ethnic, national and regional groups. The united Europe is to become not exactly a federation of countries, but rather the home of homes. In the everyday life of the new united Europe the system of norms, values and patterns of religious and cultural behaviour are going to be verified. Both the sceptics and the enthusiasts of the integration process are looking for a place and a role for the Polish Christians in the secularized European society. (shrink)

In contemporary democracies, the image that political leaders project is of central importance to their electoral appeal, however, studies of image projection have mainly been based on textual messages, undermining often visual content such as photos, memes and postcards. This study explores populist leaders image projection through visuals on Facebook in a cross-national context, with the aim of verifying if politicians use images to promote their political action or if they instead implement more complex strategies of self-branding and personalisation. (...) The analysis focuses on the election campaign period for the 2019 European elections and proposes a comparison between four leaders that joined the European Parliament’s Group of Identity and Democracy, namely Matteo Salvini for Italy, Heinz-Christian Strache for Austria, Marine Le Pen for France and Alice Weidel for Germany. According to our analysis, important differences emerge in the use that leaders make of the images disseminated on Facebook. Some of them, in fact, disseminate almost exclusively images that are strictly related to their electoral campaign, while others seek a true identification with their voters, following the pattern of intimization.

Luigi Giussani, a high school religion teacher throughout the 1950s and 1960s, grounded his teachings in the vast body of experience to be found in Christianity's two-thousand-year history. He told his students, “I'm not here to make you adopt the ideas I will give you as your own, but to teach you a method for judging the things I will say.” Throughout his life, education was one of Giussani's primary intellectual interests. He believed that effective education required an adequate background (...) in the Christian tradition, presented within a lived experience that underscored the capacity of the faith to answer universal questions. What he proposed was a process that allowed one to sift through tradition, critically examining it and comparing it against the ultimate criteria for judgment: the desires of the heart. In Giussani's view, the primary concern was to “educate the human heart as God made it.” In The Risk of Education he states that fear leads students to associate this process of criticism with negativity or doubt. Yet, without an education in criticism, students cannot develop conviction. At a time when young people are abandoning the church and questioning the value of faith, Giussani's method of judging and verifying Christianity as an experience seems a necessary intervention. In The Risk of Education he argues that, ultimately, education and the Christian message reveal themselves through human freedom. (shrink)

In this work, we investigated a covert communication method in wireless networks, which is realized by multiantenna full-duplex single relay. In the first stage, the source node sends covert messages to the relay, and the relay uses a single antenna to send interference signals to the adversary node to protect the covert information being transmitted. In the second stage, the relay decodes and forwards the covert information received in the first stage; at the same time, the relay uses zero-forcing (...) beamforming to send interference signals to the warden to ensure covert transmission. The detection error rate, transmission outage probability, maximum effective covert rate, and other performance indicators are derived in two stages, and the total performance of the system is derived and analyzed. Then, the performance indicators are verified and analyzed by simulation. Our analysis shows that the maximum effective covert rate of using the characteristics of multiantenna to interfere with Willie in the second stage is taken as the total covert performance of the system, and the transmission interruption probability is significantly less than that of the first stage, so the corresponding maximum effective concealment efficiency will be greater.

The network-based cooperative information spreading is a widely existing phenomenon in the real world. For instance, the spreading of disease outbreak news and disease prevention information often coexist and interact with each other on the Internet. Promoting the cooperative spreading of information in network-based systems is a subject of great importance in both theoretical and practical perspectives. However, very limited attention has been paid to this specific research area so far. In this study, we propose an effective approach for identifying (...) the influential latent edges which, if added to the original network, can promote the cooperative susceptible-infected-recovered dynamics. To be specific, we first obtain the probabilities of each nodes being in different node states by the message-passing approach. Then, based on the state probabilities of nodes obtained, we come up with an indicator, which incorporates both the information of network topology and the co-SIR dynamics, to measure the influence of each latent edge in promoting the co-SIR dynamics. Thus, the most influential latent edges can be located after ranking all the latent edges according to their quantified influence. We verify the rationality and superiority of the proposed indicator in identifying the influential latent edges of both synthetic and real-world networks by extensive numerical simulations. This study provides an effective approach to identify the influential latent edges for promoting the network-based co-SIR information spreading model and offers inspirations for further research on intervening the cooperative spreading dynamics from the perspective of performing network structural perturbations.

In current philosophy of information, different authors have been supporting the veridicality thesis (VT). According to this thesis, an epistemically-oriented concept of information must have truth as one of its necessary conditions. Two challenges can be raised against VT. First, some philosophers object that veridicalists erroneously ignore the informativeness of false messages. Secondly, it is not clear whether VT can adequately explain the information considered in hypothetical reasoning. In this sense, logical diagrams offer an interesting case of analysis: by (...) manipulating a logical diagram we can verify that a certain conclusion follows from a set of premises, but it cannot help us to determine the actual truth-value of a given set of propositions. Focusing on the latter challenge, in this paper I claim that logical diagrams set out potential counterexamples to VT and, consequently, pose a real challenge to this thesis. First, a veridicalist analysis of logical diagrams requires the assumption of metatheoretical properties which are not satisfied by some logical systems (and, consequently, are not satisfied by some systems of logical diagrams). So, VT does not fit well as a general framework for a theory of logical diagrammatic information. Secondly, based on semantic inferentialism, one can propose a normative interpretation of the inferential content of logical diagrams not exposed to the problems faced by VT. Moreover, there are several reasons to believe that veridicalism cannot accommodate such a normative interpretation. In other words, normativism represents a real (though still underexplored) alternative to veridicality. Due to these reasons, I conclude that, until further research, we should adopt a more parsimonious standpoint and say that logical diagrams provide inferential information simply. (shrink)

Internet users fill in interactive forms with multiple fields, check/uncheck checkboxes, select options and agree to submit. People give their consents without keeping track of them. Dominance of the machine producing human consent is ubiquitous. Humanless bureaucratic procedures become embedded into routine usage of digital products and services automating human behavior. This bureaucracy does not make individuals wait in conveyor-like lines (which sometimes can cause a collective action), it patiently waits or suddenly pops up in an annoying message requiring immediate (...) action and consuming time. It follows pre-installed procedures so cannot be distracted or appealed to. It lacks what Sofia Ranchordás calls ‘administrative empathy’. Users can hardly reach through bureaucratic procedures and communicate with another human. An individual involved in these sequences of actions contributes to increasing the quantity of bureaucratic procedures. The algorithmic bureaucracy power resides in the limited ability of human beings to make conscious and informed decisions when dealing with high complexity levels. This ubiquity makes it virtually impossible for individuals to track and verify statuses and control binding power of all legal actions on the platform. The authors apply critical analysis to explore social implications, threats and possible alternatives for corporate and governmental algorithmic bureaucracy in the emerging digital society. (shrink)

It’s morning. You sit down at your desk, cup of coffee in hand, and prepare to begin your day. First, you turn on your computer. Once it is running, you check your e-mail. Having decided it is all spam, you trash it. You close the window on your e-mail program, but leave the program running so that it will periodically check the mail server to see whether you have new mail. If it finds new mail it will alert you by (...) playing a musical tone. Next you start your word processor. You have in mind to write a paper in moral philosophy about whether people who send spam deserve capital punishment. So you open a new window and type several paragraphs of text into it. You like what you wrote, so you save it, creating a file. Later, you have more thoughts about spam and capital punishment, so you open the file again and make some changes. Then it is time to go to class. You turn off your word processor, but leave your computer running so that your email program can collect your e-mail. This mundane sequence of events can seem philosophically puzzling when we think about it carefully. While in your word processor, you opened several windows, entered text into them, and created files. What sorts of things are these files, windows, and text? It might seem that windows are easy to understand. You can, after all, see windows. That is the whole point of them. You see a window by seeing a pattern on the surface of your monitor. Isn’t the window identical with that physical pattern? But that is too quick. First, you can turn your monitor off. The window is still open. You can type text into it, and if you turn the monitor back on you can verify that you made that change. Second, you can drag another window in front of the original window. The original window disappears from view, but it still exists. Things may be happening in it that you cannot see. For example, if it is an e-mail window, new messages may be listed in it as they are 1 downloaded.. (shrink)

A large body of information and opinion related to COVID-19 is being shared via social media platforms. Recent reports have raised concerns about the reliability and verifiability of said information being disseminated and the way systems, processes and design of the platforms facilitates such spread. This, alongside other areas of concern, has resulted in several social media platforms taking steps towards tackling the spread of mis- and dis-information. Here we discuss approaches to online public health messaging from a range of (...) sources during COVID-19, with a focus on official and non-official sources in the United Kingdom. We highlight issues for ongoing public health decisions, and the potential impact for the future course of the pandemic. (shrink)

The traditional argument of Muslim theologians that aims to verify the claims of a true prophet and distinguish him from an impostor is based on the acceptance of miracles performed in history and testified through an uninterrupted chain of tradition. A second argument that equally involves transmission through tawātur is based on the prophet’s virtuous and impeccable character establishing the trustworthiness of the prophet. These are, for instance, the types of proofs mentioned by the Baghdadian Mu‘tazilī al-Gˇāhiz in his monograph (...) Huˇgaˇg al-nubuwwa. For theologians of the Aš‘arite school this approach to the verification of prophecy posed a problem. According to classical Aš‘arite theology, good is what God commands and bad is what he forbids. If God chooses prophets to reveal knowledge about what is right and what is wrong, and thus also reveal knowledge about how to live a virtuous life, how can those whom the prophets call upon know that the prophets have a virtuous character before they even know the criteria for virtue? Early Aš‘arite theologians indeed accepted that all prophets had a most virtuous character. This fact, however, became apparent only after their message gained acceptance within their community and it cannot be regarded as a viable verification of the claim of a prophet to those he calls upon. Al-Aš‘arī, for instance, is said to have accepted a number of indications that allow humans to distinguish a prophet from ordinary people. He does not mention the claim based on the impeccable moral conduct of prophets. In fact, he stresses that in order to distinguish a true prophet from other people who are close to God, but who have no message to reveal, one should put oneÕs trust only in the occurrence of true prophetic miracles.

In lieu of an abstract, here is a brief excerpt of the content:BEING AND ONE THEOLOGIAN I PROPOSE EXPLORING the view of being of one theologian whose work has received wide attention both in Germany and America. Wolfhart Pannenberg is known primarily through his formulation of the seven controversial theses in (and on the subject of) Revelation as History (1961), and through his development of this approach into a full-fledged theological methodology "from below" in Jesus'God and Man (1964) and Theology (...) a:ttd the Philosophy of Scienc :e (1973). Yet philosophers and theologians have not failed to notice that some rather interesting and novel ontological speculation has accompanied the work of this philosophically oriented theologian, speculation that could represent the seed of a novel approach to contemporary ontology. Now Pannenberg's passing references to God',s being, and to being in general, could be criticized from a theological perspective ; perhaps he would even prefer a treatment along such lines. However, another line of approach also suggests itself: if one can show that Pannenberg is advocating a way of viewing being in general, how does his approach fare when taken as the foundation of a SY'stematic ontology? Is it more at home in olassical philosophical thought about being or, if not, what contemporary influences does it reflect? Of course, for manyif not most-theologians, to attempt such an abstraction would be to tear their theology asunder, joint from marrow. For example, Barth's doctrine of the becoming God, as Eberhart Jiingel has admirably shown, is designed to do justice only to the God of revelation, and is meant to be taken as prior to all philosophical speculation about God's being and being in general.1 1 Eberhart Jiingel, Gottes Sein ist in Werden (Tiibingen, 1965), e.g. pp. 9f, 73ff; cf. Barth's Kiroh7iohe Dogmatik, II/I, pp. 202f. 645 646 PHILIP CLAYTON But lying at the heart of Pannenberg's theology is the refusal to shield his theology in this way. Theology is the science of God as the all-determining reality (TPS 302ff),2 and faith cannot defend any statement that reason fails to verify (Jesus 109). As his recent anthropology sorties into behavioral psychology, sociobiology and philosophical anthropology to produce an" anthropology in theological perspective" rather than a theological anthropology, so we may also expect a readiness on Pannenberg's part to consider his ontological statements as " ontological hypotheses" (if this is not a contradictio in adjecto ), to be tested by means of their" fit" with general speculation on the nature of being. Indeed, in BQT II: 237 and TPS, Chapter 5, he explicitly asks us to try the biblical understanding of reality in the court of the " contemporary experience of reality." Elsewhere, in a direct discussion of ontology, Pannenberg uses theological subject matter as an "example" meant to " contribute to a better understanding " of the philosophical issues involved (TKG 132f). 1. The Pannenbergian Ontology Assuming the validity of my admitted abstraction and of an unashamedly philosophical rather than theological analysis, what is this "novel" view of being found in Pannenberg's writings? Pannenberg holds that "futurity" is fundamental for Jesus' message (TKG 54). All reality is "eschatologically oriented "-in philosophical terms, referred to (bezogen auf) the future-and God is "the God of the coming kingdom" (BQT II: 237), "the God of history" (Grundfragen 112-28), "the power of the future" (TKG 57). This is not merely an 2 In the following I will use the common abbreviations for Pannenberg's works: 'TPS' for Theology and the Philosophy of Science (Philadelphia, 1976) ; ' BQT' for Basic Questions in Theology, 2 vols.

Researchers have used attribution theory as a basis for exploring the relationship between consumers'' inferences of advertiser motivation (attributions) and advertising response. This study postulated the existence of two new types of attributions which relate to the perceived ethics of the advertiser (advertiser ethical attributions) and the advertising message (message ethical attributions). Research conducted among a nationally representative sample of 273 adults: (1) verified the existence of both advertiser and message ethical attributions, (2) demonstrated the independence of advertiser and message (...) ethical attributions both from each other and from other measures of advertiser and message evaluation, (3) identified the specific advertising characteristics which lead to the formation of each type of ethical attribution and (4) demonstrated a significant relationship between advertiser and message ethical attributions and measures of advertising response.

ArgumentDuring the second quarter of the nineteenth century, an argument raged about the identity of a small freshwater fish: was the parr a distinct species, or merely the young of the salmon? This “Parr Controversy” concerned both fishermen and ichthyologists. A central protagonist in the controversy was a man of ambiguous social and scientific status: a gamekeeper from Scotland named John Shaw. This paper examines Shaw’s heterogeneous practices and the reception of his claims by naturalists as he struggled to find (...) a footing on the “gradient of attributed competence” (Rudwick 1985). The case demonstrates the context-specific nature of expert-lay boundaries and identities and explores a range of material and linguistic resources available for negotiating them. Arguing for a view of Shaw’s trajectory as simultaneously one of being a “practical man” and of becoming a naturalist, the paper explores both the permeability of social hierarchies in knowledge production and their effective role in the regulation of competency.

The continuing relevance of Ludwik Fleck’s work, above its status as a classic in science studies, lies in his reflexive conceptualisation of an open epistemology. As early as 1929, in the midst of a broad debate about a ‘crisis’ of science, Fleck offered a socio-historical analysis of the widely assumed crisis in form of an epistemology. He presented his argument, which was in itself an interrogation of the metaphysical foundations of science, as a reflexive and political intervention to this debate. (...) His book of 1935, Genesis and development of a scientific fact, in which he developed the notion of the thought collective, can be read in a similar vein as a functional analysis of science under National Socialism. His traumatic experiences during this period fostered his drive for science, democracy and epistemology. When he returned to the epistemological debate in 1946, he sharpened the presentation of his argument, presenting it rhetorically as an ironic political dialogue. This surprising text unfolds as an epistemological intervention by a participant observer. In this respect, Fleck’s epistemology, combining the historical analysis with reflexive intervention, is still a message in a bottle. (shrink)

This chapter contains sections titled: Limits for Uncommunicative Partners How Much Does a Particle Need to Know? Evaluation of Results Simulators Does Nature Simulate?

We will study several weak axiom systems that use the Subtraction and Division primitives (rather than Addition and Multiplication) to formally encode the theorems of Arithmetic. Provided such axiom systems do not recognize Multiplication as a total function, we will show that it is feasible for them to verify their Semantic Tableaux, Herbrand, and Cut-Free consistencies. If our axiom systems additionally do not recognize Addition as a total function, they will be capable of recognizing the consistency of their Hilbert-style deductive (...) proofs. Our axiom systems will not be strong enough to recognize their Canonical Reflection principle, but they will be capable of recognizing an approximation of it, called the "Tangibility Reflection Principle". We will also prove some new versions of the Second Incompleteness Theorem stating essentially that it is not possible to extend our exceptions to the Incompleteness Theorem much further. (shrink)

This is a case-study in knowledge representation and dynamic epistemic protocol verification. We analyze the ‘one hundred prisoners and a lightbulb’ puzzle. In this puzzle it is relevant what the agents know, how their knowledge changes due to observations, and how they affect the state of the world by changing facts, i.e., by their actions. These actions depend on the history of previous actions and observations. Part of its interest is that all actions are local, i.e. not publicly observable, and (...) part of the problem is therefore how to disseminate local results to other agents, and make them global. The various solutions to the puzzle are presented as protocols. The paper consists of three parts. First, we present different versions of the puzzle, and their solutions. This includes a probabilistic version, and a version assuming synchronicity. The latter is very informative for the prisoners, and allows different protocols. Then, we model the puzzle in an epistemic logic incorporating dynamic operators for the effects of information changing events. Such events include both informative actions, where agents become more informed about the non-changing state of the world, and factual changes, wherein the world and the facts describing it change themselves as well. Finally, we verify the basic protocol to solve the problem. Novel contributions in this paper are: Firstly, Protocol 2 and Protocol 4. Secondly, the modelling in dynamic epistemic logic in its entirety — we do not know of a case study that combines factual and informational dynamics in a setting of non-public events, or of a similar proposal to handle asynchronous behaviour in a dynamic epistemic logic. Thirdly, our method to verify dynamic epistemic protocols by reasoning over possibly infinite execution sequences of these protocols. A precursor of the present paper, entitled ‘One hundred prisoners and a lightbulb – logic and computation’, was presented at KR 2010, Toronto. The differences with the present contribution are as follows: the former contains a section with computational results, whereas the focus of the present paper is the verification of one of the presented protocols in the former.

Affirmative action programs remain controversial, I suspect, partly because the familiar arguments for and against them start from significantly different moral perspectives. Thus I want to step back for a while from the details of debate about particular programs and give attention to the moral viewpoints presupposed in differenttypesof argument. My aim, more specifically, is to compare the “messages” expressed when affirmative action is defended from different moral perspectives. Exclusively forward-looking (for example, utilitarian) arguments, I suggest, tend to express (...) the wrong message, but this is also true of exclusively backward-looking (for example, reparation-based) arguments. However, a moral outlook that focuses on cross-temporal narrative values (such as mutually respectful social relations) suggests a more appropriate account of what affirmative action should try to express. Assessment of the message, admittedly, is only one aspect of a complex issue, but it is a relatively neglected one. My discussion takes for granted some common-sense ideas about the communicative function of action, and so I begin with these.Actions, as the saying goes, oftenspeaklouder than words. There are times, too, when only actions can effectively communicate the message we want to convey and times when giving a message is a central part of the purpose of action. What our actions say to others depends largely, though not entirely, upon our avowed reasons for acting; and this is a matter for reflective decision, not something we discover later by looking back at what we did and its effects. The decision is important because “the same act” can have very different consequences, depending upon how we choose to justify it. (shrink)

For some time there have been appearing in the philosophical literature hints and suggestions that the so-called “problem of the external world” should be abandoned, not primarily because it is of little pragmatic significance, but rather because there is really no such problem to be solved. The publication of Reichenbach's Experience and Prediction has now stimulated a resurgence of these suggestions. In the course of his discussion of the book in the April Philosophy of Science Professor Ernest Nagel has taken (...) occasion to argue briefly that this problem, which Reichenbach attempts to solve, cannot even be stated unless one assumes its solution. And in a similar vein more recently Dr. William Barrett has also criticized Reichenbach and has then gone on to present certain fundamental logical considerations which, it is alleged, guarantee that the expression “Is there an external world?” cannot designate a legitimate philosophical problem. The situation, as he describes it, is as follows. The sentence “There is an external world” or the equivalent sentence “There is a physical object” can be confirmed in a physicalistic language only if one assumes the existence of certain physical objects. This procedure is of course circular. These sentences cannot therefore be confirmed, and, since the verifiability theory of meaning is accepted, the questions derived by transferring them into the interrogative mood cannot be meaningfully asked. A similar result is asserted to follow if one employs a perception language for science in place of a physicalistic language, since there is a parallelism between these two languages such that for every expression in the one there will be a corresponding expression in the other.

Faces are characterized by the simultaneous presence of several evaluation-relevant features, for example, emotional expression and (prejudiced) ethnicity. The social message account (SMA) hypothesizes the immediate integration of emotion and ethnicity. According to SMA, happy in-group faces should be interpreted as benevolent, whereas happy out-group faces should be interpreted as potentially malevolent. By contrast, fearful in-group faces should be interpreted as signaling an unsafe environment, whereas fearful out-group faces should be interpreted as signaling inferiority. In contrast, the processing conflict account (...) (PCA) assumes that each face conveys two rather independent evaluative features, emotion and ethnicity. Thus, stimuli might be either affectively congruent or incongruent, and thereby exert influences on behavior. The article reviews the evidence with regard to the two accounts before reporting an experiment that aims at disentangling them. In an approach/avoidance task (AAT), either happy/fearful faces of German and Turks were presented or happy/fearful faces of young and old persons. There are prejudices against Turk/Middle-eastern persons (in Germany) as well as against old persons. For SMA, the two prejudices are of different type; thus prediction for the AAT diverge for the two group conditions. In contrast, for PCA both group features (i.e., Turk ethnicity and old age) are negative features (in comparison to their counterparts) which are affectively congruent or incongruent to the emotional expression. Hence, the results pattern in the AAT should be comparable for the two group conditions. In accordance with SMA but in contrast to PCA, we found different patterns for the two group conditions.

In lieu of an abstract, here is a brief excerpt of the content:THIS MESSAGE IS FOR YOU. MAYBE. by Joseph Agassi There is a mood often enough conjured in science fiction literature to be familiar to every fan, the mood of seemingly intentional yet probably remdom contact between two individuals across immense space-time expanses. The hero of a complicated chase story has lost contact with the mother planet, has long ago leuided on a strange pleuiet, emd there, right now, just (...) walking across the plaza he sees a huge poster, with a piece of commercial advertisement or some similar message of purely local import printed on it. The poster is decorated with an arabesque which puzzles him, quickens his pulse, intrigues him, fascinates him — until it hits him insteinteuneously in full force: the arabesque is a message, written in his own native language, telling him how to reestablish contact. The story, as I say, has many veurietnts. And it has, it seems, a very widespread appeal. It is couched in terms of adventure stories, but its mood is not diat of adventure. The mood is more of die one associated with the idea of the eterned return, die idea of timelessness or of time standing still (and space vanishing), the idea the western philosophies usually associate with the ideas of Nicholas, the Renaissance mystic bishop ofCusa, though it is a recurrent idea in many cultures, of the identity of the vanishingly smedl and the infinitely large. Indeed, the meeting of the message and the recipient is symbolized by the meeting of the infinite line and the point of vanishing length. Whence this universality? I suppose it is a fact of biological nature. Think of the scent a living thing, be it a fish or em emtelope, leaves behind to contact a possible mate. It is a few complex molecules in a sea of molecules of astronomical numbers: just this room contains more molecules than you can imagine. And the animal follows a long tortuous path to find its mate. According to Willietm Craig and Konrad Lorenz, an animal does not have the slightest clue what it is after. Even while building a nest it has no complete 95 96Philosophy and Literature picture of its task. In each of its stages it goes after diverse kinds of things, yet it knows not which things, let alone their inborn rigidly fixed sequence. Yet the animal in charge of a tetsk, whether of finding a mate or of finding a twig for a nest, will be resdess — say Craig and Lorenz — and move about, and try to read the message in any piece of arabesque, until one day one piece of arabesque will med«: sense and enable its finder to complete die next step in the mysterious complex task and open up die search for the next message, the next step further along die unfolding series of preordained ordeals that life is strewn widi. Consider writing proper, like my writing this message for you right now. We do not know the background to literacy, much less its actual origins, except that these were far from unique: though many cultures eire illiterate or have acquired literacy from more evolved neighbors, mere eire many places on earth where literacy evolved independently. Yet even here we see a sequence: many independent ideographic scripts, some ofthem evolving into syllabic scripts and one or two of these evolving into an alphabet proper. How and why, we do not know. There is room for speculation, though. It is hard to imagine how the very first writer conceived of the very first message he wrote without consulting his recipient first. There are a few possible explemations here. First, that writer and recipient are one: writing was a form ofmemorizing, or ofconsigning matters to memory more stable than that of the human brain — the granite rock, for instance. The ancient Egyptian god of literacy was the god of memory. Primitive shepherds use knots in their rope and cuts on their sticks as aides memoire, as bookkeeping of sorts, and scholars consider these the origins of writings. This is evidenced by the runic writings of the Norse, whose letters are images of sticks with cuts on them. Yet runic writing is alphabetic and... (shrink)

Islamic culture may be labelled a ‘superculture’ on account of its richness, whose living message goes from the peasants of the Indian subcontinent to Africa, for instance, dating back fourteen centuries in time. The author contrasts with an Islam that is frozen in its medieval form an Islam capable of inventing new solutions. The drama of today’s Muslim populations is living under the sign of a failure to adapt, because there has been no adequate analysis of the demands of their (...) time. But there is a social message in Islam, of brotherhood, justice, effort, liberation, which remains to be translated into a project for joint action for current generations. There is integration, the complementarity of individual action, collective effort and spirituality. But the integration of the sacred into social life is so ‘un-contemporary’ that in Islamic lands an extra effort is required to grasp its true implications. (shrink)

The pervasive contrast in modern life between the certainties of science and technology, on the one hand, and the uncertainties of human goals and policies, on the other, is the objective source of a fundamental conflict in theory. It is now widely held that facts are rather definitely verifiable, but that values are unverifiable; though other students assume that values are also verifiable in some significant sense and degree.

Stephens, EditorIt is now six years since this journal’s founding editor Victoria Davion sadly succumbed to premature fatal illness and I took over her editorial duties under the most unfortunate of circumstances. I stated publicly then that Vicky’s vision for the character and purpose of the journal would remain unchanged under my watch, and in keeping with that pledge, I am now pleased (...) to announce a major expansion of our editorial board to further promote that vision.Over the past two decades, the size of our board had declined significantly as a result of retirements and mortality, and so a restoration of the previous scale of editorial support was significantly overdue. In doing this, I have sought to protect and expand our international and interdisciplinary coverage in a way that honors the focus that Vicky gave the journal from the beginning, giving space to voices from the wider communities of concern impacted by ecological destruction and incorporating a broad and inclusive but critically engaged approach to the philosophical issues involved. Our new board includes members from a wider range of nations and disciplines, which should help us expand the journal’s reach while both manifesting and remaining faithful to the original mission that our founding editor set for it. In the process, we are welcoming a combination of new rising stars and well-established respected figures in environmental thought, and aiming to expand our sphere of influence well beyond our main subscriber base in North America. Our hope is that our new scholarly supporters will enable the journal to grow in tackling the newer and ever more complex issues and problems raised by climate change, biodiversity loss, and other ongoing ecological crises, while at the same time still remaining true to the spirit with which Vicky founded it.Readers, please join me in welcoming our new board members, who are listed in the front matter of this issue. We thank them immensely for their service and hope that their efforts will enable and support increased success for Ethics and the Environment.

“Evidence” in the form of data collected and analysis thereof is fundamental to medicine, health and science. In this paper, we discuss the “evidence-based” aspect of evidence-based medicine in terms of statistical inference, acknowledging that this latter field of statistical inference often also goes by various near-synonymous names—such as inductive inference (amongst philosophers), econometrics (amongst economists), machine learning (amongst computer scientists) and, in more recent times, data mining (in some circles). Three central issues to this discussion of “evidence-based” are (i) (...) whether or not the statistical analysis can and/or should be objective and/or whether or not (subjective) prior knowledge can and/or should be incorporated, (ii) whether or not the analysis should be invariant to the framing of the problem (e.g. does it matter whether we analyse the ratio of proportions of morbidity to non-morbidity rather than simply the proportion of morbidity?), and (iii) whether or not, as we get more and more data, our analysis should be able to converge arbitrarily closely to the process which is generating our observed data. For many problems of data analysis, it would appear that desiderata (ii) and (iii) above require us to invoke at least some form of subjective (Bayesian) prior knowledge. This sits uncomfortably with the understandable but perhaps impossible desire of many medical publications that at least all the statistical hypothesis testing has to be classical non-Bayesian—i.e. it is not permitted to use any (subjective) prior knowledge.
