Algorithms wield increasing control over our lives—over the jobs we get, the loans we're granted, the information we see online. Algorithms can and often do wield their power in a biased way, and much work has been devoted to algorithmic bias. In contrast, algorithmic neutrality has been largely neglected. I investigate algorithmic neutrality, tackling three questions: What is algorithmic neutrality? Is it possible? And when we have it in mind, what can we learn about algorithmic bias?

The standard view in social science and philosophy is that lying does not require the liar’s assertion to be false, only that the liar believes it to be false. We conducted three experiments to test whether lying requires falsity. Overall, the results suggest that it does. We discuss some implications for social scientists working on social judgments, research on lie detection, and public moral discourse.

Researchers have debated whether there is a relationship between a statement’s truth-value and whether it counts as a lie. One view is that a statement being objectively false is essential to whether it counts as a lie; the opposing view is that a statement’s objective truth-value is inessential to whether it counts as a lie. We report five behavioral experiments that use a novel range of behavioral measures to address this issue. In each case, we found evidence of a relationship. (...) A statement’s truth-value affects how quickly people judge whether it is a lie. When people consider the matter carefully and are told that they might need to justify their answer, they are more likely to categorize a statement as a lie when it is false than when it is true. When given options that inhibit perspective-taking, people tend to not categorize deceptively motivated statements as lies when they are true, even though they still categorize them as lies when they are false. Categorizing a speaker as “lying” leads people to strongly infer that the speaker’s statement is false. People are more likely to spontaneously categorize a statement as a lie when it is false than when it is true. We discuss four different interpretations of relevant findings to date. At present, the best supported interpretation might be that the ordinary lying concept is a prototype concept, with falsity being a centrally important element of the prototypical lie. (shrink)

God is said to be Spirit, but the language of spirit is ignored in contemporary philosophy of religion. As well as exploring the notion of spirit in Hegel, Romanticism and Kierkegaard, participants explore the view that God is a spirit without a body, and the relations between "spirit" and "truth.".

In this paper we consider conditional random quantities (c.r.q.’s) in the setting of coherence. Based on betting scheme, a c.r.q. X|H is not looked at as a restriction but, in a more extended way, as \({XH + \mathbb{P}(X|H)H^c}\) ; in particular (the indicator of) a conditional event E|H is looked at as EH + P(E|H)H c . This extended notion of c.r.q. allows algebraic developments among c.r.q.’s even if the conditioning events are different; then, for instance, we can give a (...) meaning to the sum X|H + Y|K and we can define the iterated c.r.q. (X|H)|K. We analyze the conjunction of two conditional events, introduced by the authors in a recent work, in the setting of coherence. We show that the conjoined conditional is a conditional random quantity, which may be a conditional event when there are logical dependencies. Moreover, we introduce the negation of the conjunction and by applying De Morgan’s Law we obtain the disjoined conditional. Finally, we give the lower and upper bounds for the conjunction and disjunction of two conditional events, by showing that the usual probabilistic properties continue to hold. (shrink)

In this book, Phillip Wiebe examines religious, spiritual, and mystical experiences, assessing how these experiences appear to implicate a spiritual order. Despite the current prevalence of naturalism and atheism, he argues that experiences purporting to have a religious or spiritual significance deserve close empirical investigation. Wiebe surveys the broad scope of religious experience and considers different types of evidence that might give rise to a belief in phenomena such as spirits, paranormal events, God, and an afterlife. He demonstrates that (...) there are different explanations and interpretations of religious experiences, both because they are typically personal accounts, and they suggest a reality that is often unobservable. Wiebe also addresses how to evaluate evidence for theories that postulate unobservables in general, and a Theory of Spirits in particular. Calling for more rigorous investigation of these phenomena, Wiebe frames the study of religious experience among other accepted social sciences that seek to understand religion. (shrink)

We study probabilistically informative (weak) versions of transitivity by using suitable definitions of defaults and negated defaults in the setting of coherence and imprecise probabilities. We represent p-consistent sequences of defaults and/or negated defaults by g-coherent imprecise probability assessments on the respective sequences of conditional events. Moreover, we prove the coherent probability propagation rules for Weak Transitivity and the validity of selected inference patterns by proving p-entailment of the associated knowledge bases. Finally, we apply our results to study selected probabilistic (...) versions of classical categorical syllogisms and construct a new version of the square of opposition in terms of defaults and negated defaults.

We generalize, by a progressive procedure, the notions of conjunction and disjunction of two conditional events to the case of n conditional events. In our coherence-based approach, conjunctions and disjunctions are suitable conditional random quantities. We define the notion of negation, by verifying De Morgan’s Laws. We also show that conjunction and disjunction satisfy the associative and commutative properties, and a monotonicity property. Then, we give some results on coherence of prevision assessments for some families of compounded conditionals; in particular (...) we examine the Fréchet-Hoeffding bounds. Moreover, we study the reverse probabilistic inference from the conjunction Cn+1 of n + 1 conditional events to the family {Cn,En+1|Hn+1}. We consider the relation with the notion of quasi-conjunction and we examine in detail the coherence of the prevision assessments related with the conjunction of three conditional events. Based on conjunction, we also give a characterization of p-consistency and of p-entailment, with applications to several inference rules in probabilistic nonmonotonic reasoning. Finally, we examine some non p-valid inference rules; then, we illustrate by an example two methods which allow to suitably modify non p-valid inference rules in order to get inferences which are p-valid.

A standard view in social science and philosophy is that a lie is a dishonest assertion: to lie is to assert something that you think is false in order to deceive your audience. We report four behavioral experiments designed to evaluate some aspects of this view. Participants read short scenarios and judged several features of interest, including whether an agent lied. We found evidence that ordinary lie attributions can be influenced by aspects of audience uptake, are based on judging that (...) the agent made an assertion (assertion attributions), and, at least in some contexts, are not based on attributions of deceptive intent. The finding on assertion attributions is predicted by the standard view, but the finding on intent attributions is not. These results help to further clarify the ordinary concept of lying and shed light on the psychological processes involved in ordinary lie attributions and related judgments. (shrink)

This paper presents an introductory overview of the main issues that the digitalisation of industrial enterprises known as Industry 4.0 raises for social sciences. First, it will show that this technological transition—which, however, is unfinished and is seen to be in continuity with the so-called “third industrial revolution”—cannot be interpreted with reference to a deterministic approach. It can be analysed more usefully as a range of decisions affecting the industrial policies of national states, the conception and design of machines, their (...) adoption in production processes and finally their use by operators. Second, certain aspects of Industry 4.0 of special concern in terms of organisation of work processes will be analysed on various scales. Finally, we will explain various hypotheses that social and economic research is developing with regard to the new technologies’ controversial effects on employment. (shrink)

This article re-examines the theoretical basis for environmental and heritage interpretation in tourist settings in the light of hermeneutic philosophy. It notes that the pioneering vision of heritage interpretation formulated by Freeman Tilden envisaged a broadly educational, ethically informed and transformative art. By contrast, current cognitive psychological attempts to reduce interpretation to the monological transmission of information, targeting universal but individuated cognitive structures, are found to be wanting. Despite growing signs of diversity, this information processing approach to interpretation remains dominant. (...) The article then presents the alternative paradigm of hermeneutics through the works of Schleiermacher, Dilthey, Heidegger and Gadamer, to provide a broader interpretation of interpretation. This not only captures the essence of Tilden’s definition but construes heritage interpretation as a more inclusive, culturally situated, critically reflexive and dialogical practice. (shrink)

We claim that scientists working with deep learning (DL) models exhibit a form of pragmatic understanding that is not reducible to or dependent on explanation. This pragmatic understanding comprises a set of learned methodological principles that underlie DL model design-choices and secure their reliability. We illustrate this action-oriented pragmatic understanding with a case study of AlphaFold2, highlighting the interplay between background knowledge of a problem and methodological choices involving techniques for constraining how a model learns from data. Building successful models (...) requires pragmatic understanding to apply modelling strategies that encourage the model to learn data patterns that will facilitate reliable generalisation. (shrink)

In this study, we explore the relation between scientific literacy and unwarranted beliefs. The results show heterogeneous interactions between six constructs: conspiracy theories poorly interact with scientific literacy; there are major differences between attitudinal and practical dimensions of critical thinking; paranormal and pseudoscientific beliefs show similar associations ; and, only scientific knowledge interacts with other predictor of unwarranted beliefs, such as ontological confusions. These results reveal a limited impact: science educators must take into account the complex interactions between the dimensions (...) of scientific literacy and different types of unwarranted beliefs to improve pedagogical strategies.

Social work is a contested tradition, torn between the demands of social governance and autonomy. Today, this struggle is reflected in the division between the dominant, neoliberal agenda of service provision and the resistance offered by various critical perspectives employed by disparate groups of practitioners serving diverse communities. Critical social work challenges oppressive conditions and discourses, in addition to addressing their consequences in individuals’ lives. However, very few recent critical theorists informing critical social work have advocated revolution. A challenging exception (...) can be found in the work of Cornelius Castoriadis (1922–97), whose explication of ontological underdetermination and creation evades the pitfalls of both structural determinism and post-structural relativism, enabling an understanding of society as the contested creation of collective imaginaries in action and a politics of radical transformation. On this basis, we argue that Castoriadis’s radical-democratic revisioning of revolutionary praxis can help in reimagining critical social work’s emancipatory potential. (shrink)

Why equality cannot be conditional on a shared human “nature” but has to be for all For centuries, ringing declarations about all men being created equal appealed to a shared human nature as the reason to consider ourselves equals. But appeals to natural equality invited gradations of natural difference, and the ambiguity at the heart of “nature” enabled generations to write of people as equal by nature while barely noticing the exclusion of those marked as inferior by their gender, race, (...) or class. Despite what we commonly tell ourselves, these exclusions and gradations continue today. In Unconditional Equals, political philosopher Anne Phillips challenges attempts to justify equality by reference to a shared human nature, arguing that justification turns into conditions and ends up as exclusion. Rejecting the logic of justification, she calls instead for a genuinely unconditional equality. Drawing on political, feminist, and postcolonial theory, Unconditional Equals argues that we should understand equality not as something grounded in shared characteristics but as something people enact when they refuse to be considered inferiors. At a time when the supposedly shared belief in human equality is so patently not shared, the book makes a powerful case for seeing equality as a commitment we make to ourselves and others, and a claim we make on others when they deny us our status as equals.

Starting from a recent paper by S. Kaufmann, we introduce a notion of conjunction of two conditional events and then we analyze it in the setting of coherence. We give a representation of the conjoined conditional and we show that this new object is a conditional random quantity, whose set of possible values normally contains the probabilities assessed for the two conditional events. We examine some cases of logical dependencies, where the conjunction is a conditional event; moreover, we give the (...) lower and upper bounds on the conjunction. We also examine an apparent paradox concerning stochastic independence which can actually be explained in terms of uncorrelation. We briefly introduce the notions of disjunction and iterated conditioning and we show that the usual probabilistic properties still hold. (shrink)

The term 'fascism' continues to be very much in currency in Philippines society. To the Filipino people, its meaning is often drawn from pained memory of wholesale deprivation of democratic rights and large-scale human rights abuses. Yet, to many, the fear of fascism has still to give way to a deeper understanding of this menace. This may hold true even among those belonging to the progressive movement. One Marxist philosopher and theoretician who gave extended treatment of the issues surrounding the (...) character and conditions giving rise to fascism was Nicos Poulantzas, whose theory is employed here to interrogate the debates about fascism in the post-Marcos Philippines context.

In view of the arguments put forward by Clifton and Monton [this volume], we reconsider the alleged conflict of dynamical reduction models with the enumeration principle. We prove that our original analysis of such a problem is correct, that the GRW model does not meet any difficulty and that the reasoning of the above authors is inappropriate since it does not take into account the correct interpretation of the dynamical reduction theories.

The context of compliance creates special challenges for research ethics education. It can serve as a positive force in promoting research integrity because it forces academic institutions to provide research ethics training, and it forces some people to complete research ethics training. However, when compliance mandates create patchwork coverage with inconsistent requirements, they can have the paradoxical effect of trivializing the very thing they intend to promote. After providing a background on research ethics education mandates from US federal funding agencies, (...) I review the way in which academic institutions tend to respond to these mandates and I explore the impact of these compliance requirements on the goals of research ethics education. Finally, I consider recent calls to harmonize federal agency requirements, and close by sharing the way in which we are trying to harmonize the requirements at my own institution. (shrink)

It follows from Humean principles of plenitude, I argue, that island universes are possible: physical reality might have 'absolutely isolated' parts. This makes trouble for Lewis's modal realism; but the realist has a way out. First, accept absolute actuality, which is defensible, I argue, on independent grounds. Second, revise the standard analysis of modality: modal operators are 'plural', not 'individual', quantifiers over possible worlds. This solves the problem of island universes and confers three additional benefits: an 'unqualified' principle of compossibility (...) can be accepted; the possibility of nothing can be accommodated; and the identity of indiscernible worlds can be decisively refuted.

This volume contains eighteen papers, three with new postscripts, that were written over the past 35 years. Five of the papers have not been previously published. Together they provide a comprehensive account of modal reality—the realm of possible worlds—from a Humean perspective, with excursions into neighboring topics in metaphysics. Part 1 sketches an account of reality as a whole, both the mathematical and the modal, defending a form of plenitudinous realism: every consistent proposition is true of some portion of reality. (...) Part 2 presents and defends a realist theory of concrete possible worlds with an absolute ontological distinction between the actual and the merely possible. Part 3 presents and defends a Humean account of modal plenitude, formulating and endorsing principles of recombination, of plenitude of possible structures, and of plenitude of alien contents. Part 4 applies the Humean account to truthmaking, mereology, spacetime, and quantities. I argue that holding fast to Humean strictures leads to views that differ in radical ways from those put forth by contemporary metaphysicians. (shrink)

Limited health literacy is a pervasive and independent risk factor for poor health outcomes. Despite decades of reports exhibiting that the healthcare system is overly complex, unneeded complexity remains commonplace and endangers the lives of patients, especially those with limited health literacy. In this article, we define health literacy and describe the empirical evidence associating health literacy and poor health outcomes. We recast the issue of poor health literacy from within the ethical perspective of the least well-off and argue that (...) poor health outcomes deriving from limited health literacy ought to be understood as a fundamental injustice of the healthcare system. We offer three proposals that attempt to rectify this injustice, including: universal precautions that presume limited health literacy for all healthcare users; expanded use of technology supported communication; and clinical incentives that account for limited health literacy.

Block () highlights two experimental studies of neglect patients which, he contends, provide ‘dramatic evidence’ for unconscious seeing. In Block's hands this is the highly non-trivial thesis that seeing of the same fundamental kind as ordinary conscious seeing can occur outside of phenomenal consciousness. Block's case for it provides an excellent opportunity to consider a large body of research on clinical syndromes widely held to evidence unconscious perception. I begin by considering in detail the two studies of neglect to which (...) Block appeals. I show why their interpretation as evidence of unconscious seeing faces a series of local difficulties. I then explain how, even bracketing these issues, a long-standing but overlooked problem concerning our criterion for consciousness problematizes the appeal to both studies. I explain why this problem is especially pressing for Block given his view that phenomenal consciousness overflows access consciousness. I further show that it is epidemic—not only affecting all report-based studies of unconscious seeing in neglect, but also analogous studies of the condition most often alleged to show unconscious seeing, namely blindsight.

Phillip Cary argues that Augustine invented or created the concept of self as an inner space--as space into which one can enter and in which one can find God. This concept of inwardness, says Cary, has worked its way deeply into the intellectual heritage of the West and many Western individuals have experienced themselves as inner selves. After surveying the idea of inwardness in Augustine's predecessors, Cary offers a re-examination of Augustine's own writings, making the controversial point that in (...) his early writings Augustine appears to hold that the human soul is quite literally divine. Cary goes on to contend that the crucial Book 7 of the Confessions is not a historical report of Augustine's "conversion" experience, but rather an explanation of his intellectual development over time.

In this chapter, I survey what I call Lewisian approaches to modality: approaches that analyze modality in terms of concrete possible worlds and their parts. I take the following four theses to be characteristic of Lewisian approaches to modality. (1) There is no primitive modality. (2) There exists a plurality of concrete possible worlds. (3) Actuality is an indexical concept. (4) Modality de re is to be analyzed in terms of counterparts, not transworld identity. After an introductory section in which (...) I motivate analyzing modality in terms of possible worlds, I devote one section to each of these four theses. For each thesis, I take Lewis’s interpretation and defense as my starting point. I then consider and endorse alternative ways of accepting the thesis, some of which disagree substantially with Lewis’s interpretation or defense. There is more than one way to be a Lewisian about modality. (shrink)

Background: Patients prescribed with medication that treats mental health conditions benefit the most compared to those prescribed with other types of medication. However, they are also the most difficult to adhere. The development of mobile health (mHealth) applications (‘apps’) to help patients monitor their adherence is fast growing but with limited evidence on their efficacy. There is no evidence on the content of these apps for patients taking psychotropic medication. The aim of this study is to identify and evaluate the (...) aims and functioning of available apps that are aiming to help and educate patients to adhere to medication that treats mental health conditions. Method: Three platform descriptions (Apple, Google and Microsoft) were searched between October 2015 and February 2016. Included apps need to focus on adherence to medication that treats mental health conditions and use at least a reinforcement strategy. Descriptive information was extracted and apps evaluated on a number of assessment criteria using content analysis. Results: Sixteen apps were identified. All apps included self-monitoring properties like reminders and psycho-educational properties like mood logs. It was unclear how the latter were used or how adherence was measured. Major barriers to medication adherence like patients’ illness and medication beliefs and attitudes were not considered nor where information to patients about mediation side effects. Very few apps were tailored and none was developed based on established theories explaining the processes for successful medication adherence like cognitions and beliefs. Reported information on app development and validation was poor. Discussion: A variety of apps with different properties that tackle both intentional and unintentional non-adherence from a different perspective are identified. An evidence-based approach and co-creation with patients is needed. This will ensure that the apps increase the possibility to impact on non-adherence. Theories like social cognition models can be useful in ensuring that patients’ education, motivation, skills, beliefs and type of adherence are taken into consideration when developing the apps. Findings from this study can help clinicians and patients make informed choices and pursue policy-makers to integrate evidence when developing future apps. Quality-assurance tools are needed to ensure the apps are systematically evaluated. (shrink)

: The transplantation of adult human neural stem cells into prenatal non-humans offers an avenue for studying human neural cell development without direct use of human embryos. However, such experiments raise significant ethical concerns about mixing human and nonhuman materials in ways that could result in the development of human-nonhuman chimeras. This paper examines four arguments against such research, the moral taboo, species integrity, "unnaturalness," and human dignity arguments, and finds the last plausible. It argues that the transfer of human (...) brain or retinal stem cells to nonhuman embryos would not result in the development of human-nonhuman chimeras that denigrate human dignity, provided such stem cells are dissociated. The article provides guidelines that set ethical boundaries for conducting such research that are consonant with the requirements of human dignity. (shrink)

To properly understand behavior, we must obtain both ultimate and proximate explanations. Put briefly, ultimate explanations are concerned with why a behavior exists, and proximate explanations are concerned with how it works. These two types of explanation are complementary and the distinction is critical to evolutionary explanation. We are concerned that they have become conflated in some areas of the evolutionary literature on human behavior. This article brings attention to these issues. We focus on three specific areas: the evolution of (...) cooperation, transmitted culture, and epigenetics. We do this to avoid confusion and wasted effort—dangers that are particularly acute in interdisciplinary research. Throughout this article, we suggest ways in which misunderstanding may be avoided in the future. (shrink)

Thomas Sankara was 33 years old when he seized power in a bloodless coup. During the four years of his governance, he organized adult literacy campaigns and mass vaccination of children, promoted women's rights and fought corruption as well as desertification caused by inappropriate agricultural practices introduced during the colonial period. Within two years, child mortality and illiteracy dropped significantly and vaccination coverage increased. Beyond these quantitative results, Sankara firmly believed that the decolonization of his country started from the formation (...) of the conscience of citizens, from learning to “rely on themselves” – materially and psychologically – and from the abandonment of a logic of technological and financial dependence that generated hunger and debt. To achieve his goals, he launched campaigns to “consume Burkinabè,” to plant trees and preserve rainwater in areas affected by desertification. (shrink)

The question of education for democratic ‘empowerment and liberation’, and how this might guide pedagogic practice is seldom raised and extremely challenging for social work education today. This chapter takes up the proposition that social work, through its educational practices, ‘can’ deliver on its promise of ‘democratic practice’ if democracy is understood as a process and not a predefined product. We argue that such a process and its embodiment in institutions cannot exist without the formation of radically democratic subjects, people (...) (including social workers) capable of questioning dominant social forms and of creating new forms and practices. Accordingly, this chapter explores the educational implications for social work of the work of the revolutionary theorist, Cornelius Castoriadis (1921–1997). Castoriadis’ philosophy accords a crucial role to democratic pedagogy (paideía) as an essential form of praxis in the creation of a radically democratic, egalitarian and sustainable society. In particular, we examine his idea (against (neo)liberal individualisation) that ‘autonomy’ is simultaneously an individual and social project that begins in, and is always dependent upon, individual and collective self-reflection. This argument is illustrated by examples from the authors’ classroom experiences of teaching both critical reflection and critical social theory to social work students in Australian universities, on the premise that both are indispensable in social work education as a democratic practice for ‘empowerment and liberation’. The chapter outlines a brief discussion of Castoriadis, his main ideas and the pedagogic dimensions of his philosophy before bringing the latter to bear on the authors’ teaching experiences.

I am a realist of a metaphysical stripe. I believe in an immense realm of "modal" and "abstract" entities, of entities that are neither part of, nor stand in any causal relation to, the actual, concrete world. For starters: I believe in possible worlds and individuals; in propositions, properties, and relations (both abundantly and sparsely conceived); in mathematical objects and structures; and in sets (or classes) of whatever I believe in. Call these sorts of entity, and the reality they comprise, (...) metaphysical. In contrast, call the actual, concrete entities, and the reality they comprise, physical. Physical and metaphysical reality together comprise all that there is. In this paper, it is not my aim to defend realism about any particular metaphysical sort of entity. Rather, I ask quite generally whether and how any brand of realism about metaphysical sorts of entity could be justified? (shrink)

Niche construction refers to the activities of organisms that bring about changes in their environments, many of which are evolutionarily and ecologically consequential. Advocates of niche construction theory (NCT) believe that standard evolutionary theory fails to recognize the full importance of niche construction, and consequently propose a novel view of evolution, in which niche construction and its legacy over time (ecological inheritance) are described as evolutionary processes, equivalent in importance to natural selection. Here, we subject NCT to critical evaluation, in (...) the form of a collaboration between one prominent advocate of NCT, and a team of skeptics. We discuss whether niche construction is an evolutionary process, whether NCT obscures or clarifies how natural selection leads to organismal adaptation, and whether niche construction and natural selection are of equivalent explanatory importance. We also consider whether the literature that promotes NCT overstates the significance of niche construction, whether it is internally coherent, and whether it accurately portrays standard evolutionary theory. Our disagreements reflect a wider dispute within evolutionary theory over whether the neo-Darwinian synthesis is in need of reformulation, as well as different usages of some key terms (e.g., evolutionary process).

En este artículo analizaremos los posibles criterios epistemológicos que, en el contexto de la filosofía hegeliana de la historia mundial, circunscriben el largo proceso revolucionario haitiano en un no-lugar narrativo. Contrario al imaginario político, económico y cultural europeo de fines del siglo XVIII y comienzos del siglo XIX, que vio en la Revolución haitiana un acontecimiento que directa o indirectamente repercute en las transformación geopolítica global, en los discursos abolicionistas y en la flujos comerciales a través del Atlántico, Hegel parece (...) en principio desatender la especificidad del proceso, aunque, como sostenemos en este contexto, es posible rastrear los motivos de una exclusión deliberada que responder a una ideas precisas de libertad y terror que anteceden, y por tanto determinan, el lugar de la Revolución haitiana en la historia mundial.

We deepen the study of conjoined and disjoined conditional events in the setting of coherence. These objects, differently from other approaches, are defined in the framework of conditional random quantities. We show that some well known properties, valid in the case of unconditional events, still hold in our approach to logical operations among conditional events. In particular we prove a decomposition formula and a related additive property. Then, we introduce the set of conditional constituents generated by $n$ conditional events and (...) we show that they satisfy the basic properties valid in the case of unconditional events. We obtain a generalized inclusion-exclusion formula, which can be interpreted by introducing a suitable distributive property. Moreover, under logical independence of basic unconditional events, we give two necessary and sufficient coherence conditions. The first condition gives a geometrical characterization for the coherence of prevision assessments on a family F constituted by n conditional events and all possible conjunctions among them. The second condition characterizes the coherence of prevision assessments defined on $F\cup K$, where $K$ is the set of conditional constituents associated with the conditional events in $F$. Then, we give some further theoretical results and we examine some examples and counterexamples. Finally, we make a comparison with other approaches and we illustrate some theoretical aspects and applications. (shrink)

Business ethics is a topic receiving much attention in the literature. However, the term 'business ethics' is not adequately defined. Typical definitions refer to the rightness or wrongness of behavior, but not everyone agrees on what is morally right or wrong, good or bad, ethical or unethical. To complicate the problem, nearly all available definitions exist at highly abstract levels. This article focuses on contemporary definitions of business ethics by business writers and professionals and on possible areas of agreement among (...) the available definitions. Then a definition is synthesized that is broad enough to cover the field of management in a sense as full as most managers might conceive of it. (shrink)

This study describes discourse features of messages posted to an Internet discussion forum about depression based on the analysis of a small corpus of message texts. The message texts were classified into three types: problem messages, advice messages and thanks messages, and salient discourse features of each message type were described and analyzed in terms of discourse function. Features of problem messages included: frequent use of metaphorical language to describe symptoms, use of or type questions to request advice, and a (...) general lack of direct requests for advice. Advice messages were characterized by casual style and exhibited a variety of discourse patterns with the common function of expressing positive regard and solidarity. The occurrence of these patterns can be related to the special interpersonal needs associated with the discourse function of giving advice. Thanks messages were responses to advice messages, and usually included some expression of thanks for advice, but interestingly, thanks message writers never indicated that they had acted upon or would act upon the advice they received.
