Background Respect for patient autonomy, the principle that patients are capable to make informed decisions about medical interventions, is fundamental in present-day medicine. However, if a patient’s request is medically not indicated, the practitioner faces an ethical dilemma represented by the conflict of the principles of patient autonomy, beneficence, and maleficence. Adjacent to topics such as medical assistance in dying and healthy limb amputation, this ethical dilemma also manifests in the care of the maxillofacial region (the oral cavity and its (...) surroundings), an area crucial to esthetic appearance, but also to everyday functions including mastication, speech, and facial expression, all of which are related to well-being. Our aim was to explore the manifestations and resolutions of the conflict between oral health and patient autonomy in relevant literature in order to contribute to the discourse of ethical challenges concerning patient autonomy, beneficence, and nonmaleficence. Methods We screened all journal articles discussing the researched ethical dilemma obtained from three databases. Two researchers developed a hierarchical coding scheme, where the parent and grandparent codes were designated deductively as: Case (situations involving the researched ethical dilemma), Judgement (decisions made in the ethical dilemma), and Principle (ideas, rules, propositions explaining the judgements); child codes were developed inductively. After coding the sources, we utilized thematic analysis to construct code constellations. Results Most themes identified in our sources advocated for the practitioner to choose the alternative that benefits the patient from a medical perspective, although no theme excluded the consideration of patient autonomy. Instances where respect for patient autonomy was encouraged concerned oral preventive care or when the requested intervention was expected to have an insignificant impact on oral health. Conclusions Ethical conflicts concerning patient autonomy, beneficence, and nonmaleficence have a marked presence in oral care. These conflicts arise through the issue of body modification, evident in cosmetic dentistry and requests for tooth extraction. Our sources generally support the argumentation for beneficence, despite the rise of cosmetic procedures in dentistry. (shrink)

The deformation and wear events that underlie microwear and macrowear signals commonly used for dietary reconstruction in fossil animals can be replicated and quantified by controlled laboratory tests on extracted tooth specimens in conjunction with fundamental micromechanics analysis. Key variables governing wear relations include angularity, stiffness (modulus), and size of the contacting particle, along with material properties of enamel. Both axial and sliding contacts can result in the removal of tooth enamel. The degree of removal, characterized by a (...) “wear coefficient,” varies strongly with particle content at the occlusal interface. Conditions leading to a transition from mild to severe wear are discussed. Measurements of wear traces can provide information about contact force and particle shape. The potential utility of the micromechanics methodology as an adjunct for investigating tooth durability and reconstructing diet is explored. (shrink)

Seeing one’s laptop to be missing, hearing silence and smelling fresh air; these are all examples of perceptual experiences of absences. In this paper I discuss an example of absence perception in the tactual sense modality, that of tactually perceiving a tooth to be absent in one’s mouth, following its extraction. Various features of the example challenge two recently-developed theories of absence perception: Farennikova’s memory-perception mismatch theory and Martin and Dockic’s meta-cognitive theory. I speculate that the mechanism underlying (...) the experience is a body schema that has failed to update itself. (shrink)

Beginning in the nineteenth century, scientists speculated that the Pleistocene megafauna—species such as the giant ground sloth, wooly mammoth, and saber-tooth cat—perished because of rapid climate change accompanying the end of the most recent Ice Age. In the 1950s, a small network of ecologists challenged this view in collaboration with archeologists who used the new tool of radiocarbon dating. The Pleistocene overkill hypothesis imagined human hunting, not climate change, to be the primary cause of megafaunal extinction. This article situates (...) the Pleistocene overkill hypothesis in a broader history of the emergence of historical ecology as a distinct sub-discipline of paleoecology. Tracing the work of the Yale Geochronometric Laboratory and an interdisciplinary research network that included Paul Sears, Richard Foster Flint, Edward Deevey, Kathryn Clisby, and Paul S. Martin, it reveals how both the methods and the meaning of studying fossil pollen shifted between the 1910s and 1960s. First used as a tool for fossil fuel extraction, fossil pollen became a means of envisioning climatic history, and ultimately, a means of reimagining global ecological history. First through pollen stratigraphy and then through radiocarbon dating, ecologists reconstructed past biotic communities and rethought the role of humans in these communities. By the 1980s, the discipline of historical ecology would reshape physical environments through the practice of ecological restoration. (shrink)

This article reviews some of the merging ethical issues in restorative dentistry. This is a branch of healthcare concerned with quality of life, since retention of functioning teeth is important in allowing a healthy diet to be consumed. Yet the supply of dentists is such that, in many of the world’s poorest countries, extraction is the only viable option for treating tooth decay. Available repair materials present various ethical problems. Silver amalgam is being phased out in much of (...) the world, because of environmental concerns with mercury, yet it is cheap and reliable. Alternatives have been developed, influenced by the West’s preoccupation with appearance, yet these materials are difficult to place and are less durable than amalgam. These concerns lead to significant ethical problems, which are explored in this article. It concludes by proposing a way to deal with the emerging ethical problems. (shrink)

Most non-human animals live in the wild and it is probable that suffering predominates in their lives due to natural events. Humans may at some point be able to engage in paradise engineering, or the modification of nature and animal organisms themselves, to improve the well-being of wild animals. We may, in other words, make nature 'red in tooth and claw' no more. We argue that this creates a tension between environmental ethics and animal ethics which is likely insurmountable. (...) First, we argue that concern for the environment can be compatible with helping individual wild animals but should see redesigning nature as morally impermissible. Second, we argue that if we are concerned with animal well-being, we may reject that we have a duty to help wild animals even to the point of redesigning nature, but we must nevertheless concede that it is permissible to do so under certain circumstances. We show how this permissibility can be derived from three animal rights views: Tom Regan's, a novel account inspired by Thomas Pogge and a libertarian approach to animal rights. (shrink)

“Nature, Red in Tooth and Claw” explores Adorno’s ideas about our mediated relationship with nature. The first section of the paper examines the epistemological significance of his thesis about the preponderance of the object while describing the Kantian features in his notion of mediation. Adorno’s conception of nature will also be examined in the context of a review of J. M. Bernstein’s and Fredric Jameson’s attempts to characterize it. The second section of the paper deals with Adorno’s Freudian account (...) of internal nature. While arguing against Joel Whitebook’s view that Adorno needs a concept of sublimation, I contend that Adorno’s genetic account of the relationship between nature and mind enables him to respond to the Freudian injunction to displace the id with the ego with a view to fostering autonomy. In the final section of the paper, problems with Adorno’s ideas about external and internal nature are briefly discussed. (shrink)

Over the last one hundred and fifty years, the extraction and processing of non-renewable resources has provided the basis for the three industrial revolutions that have led to the modern economies of the developed world. In the process, the nature of resource extraction firms has also changed dramatically, from small-scale operations exploiting easily accessible deposits to large, vertically integrated, capital intensive transnational corporations characterized by oligopolistic competition. In the last ten to fifteen years, coinciding with processes of economic (...) globalization, another major change has been occurring as resource extraction industries have been shifting their operations from developed to developing countries. This shift has greatly impacted the populations of these countries and raises a variety of ethical issues. This article investigates the nature of these changes and the ethical issues that arise, focusing in particular on the development impact of the activities of these industries and the potential adequacy of different policy approaches to regulating them.

Epithelial stem cells have been identified in integumental structures such as hairs and continuously growing teeth of various rodents, and in the gut. Here we propose the involvement of epithelial stem cells in the continuous tooth replacement that characterizes non‐mammalian vertebrates, as exemplified by the zebrafish. Arguments are based on morphological observations of tooth renewal in the zebrafish and on the similarities between molecular control of hair and tooth formation. Dissection of the molecular cascades underlying the regulation (...) of the epithelial stem cell niche might open perspectives for new regenerative treatment strategies in clinical dentistry.

Medical law and Biopolitics shed specific light on the relationship of subject and power/violence in legal contexts. For our species, medicine is an essential endeavour vis-à-vis nature which is „red in tooth and claw“. Medicine, however, is driven by autopoietic systemic imperatives and marked by relations of domination. Guaranteeing robust individual rights and legal powers is a remedy against both.

Teeth are one of the most fascinating innovations of vertebrates. Their diversity of shape, size, location, and number in vertebrates is astonishing. If the molecular mechanisms underlying the morphogenesis of individual teeth are now relatively well understood, thanks to the detailed experimental work that has been performed in model organisms (mainly mouse and zebrafish), the mechanisms that control the organization of the dentition are still a mystery. Mammals display simplified dentitions when compared to other vertebrates with only a single (...) class='Hi'>tooth row positioned in the anterior part of the mouth, whereas other vertebrates exhibit tooth rows in many locations. As proposed 60 years ago, tooth rows can be formed sequentially from an initiator tooth. Recent results in zebrafish have now largely confirmed this hypothesis. Here this observation is generalized upon and it is suggested that in most vertebrates tooth rows could form sequentially from a single initiator tooth. (shrink)

On some occasions of self-reference there can be two equally viable forms available to speakers: individual self-reference and collective self-reference. This means that selection of one or the other in talk-in-interaction can — akin to the selection of terms for reference to non-present persons — be guided by such considerations as recipient design and action formation. As a strategy for investigating the selection of self-reference terms, this article examines repairs to self-reference that change the form of reference from individual to (...) collective and vice versa. We first identify two repair operations found in the domain of self-reference: aggregation and extraction and then we track the use of both operations across a range of positions in the repair initiation opportunity space. Finally we consider some of the interactional uses of aggregation and extraction repairs in resolving sources of troubles associated with speaker epistemic authority and responsibility for described actions.

In this paper we study with proof-theoretic methods the function(al) s provably recursive relative to Ramsey's theorem for pairs and the cohesive principle (COH). Our main result on COH is that the type 2 functional provably recursive from $RCA_0 + COH + \Pi _1^0 - CP$ are primitive recursive. This also provides a uniform method to extract bounds from proofs that use these principles. As a consequence we obtain a new proof of the fact that $WKL_0 + \Pi _1^0 - (...) CP + COH$ is $\Pi _1^0 $ -conservative over PRA. Recent work of the first author showed that $\Pi _1^0 + CP + COH$ is equivalent to a weak variant of the Bolzano-Weierstraß principle. This makes it possible to use our results to analyze not only combinatorial but also analytical proofs. For Ramsey's theorem for pairs and two colors $\left( {RT_2^2 } \right)$ we obtain the upper bounded that the type 2 functionals provable recursive relative to $RCA_0 + \sum\nolimits_2^0 {IA + RT_2^2 } $ are in T₁. This is the fragment of Gödel's system T containing only type 1 recursion—roughly speaking it consists of functions of Ackermann type. With this we also obtain a uniform method for the extraction of T₁-bounds from proofs that use RT2..... Moreover, this yields a new proof of the fact that $WKL_0 + \sum\nolimits_2^0 {IA} + RT_2^2 $ is $\Pi _1^0 $ -conservative over $RCA_0 + \sum\nolimits_2^0 { - IA} $ . The results are obtained in two steps: in the first step a term including Skolem functions for the above principles is extracted from a given proof. This is done using Gödel's functional interpretation. After this the term is normalized, such that only specific instances of the Skolem functions are used. In the second step this term is interpreted using $\Pi _1^0 $ -comprehension. The comprehension is then eliminated in favor of induction using either elimination of monotone Skolem functions (for COH) or Howard's ordinal analysis of bar recursion (for $RT_2^2 $. (shrink)

Much recent philosophical work argues that power constrains speech—pornography silences women, testimonial injustice thwarts a speaker’s transmission of knowledge, bias distorts the performative force of subordinated speech. Though the constraints that power places on speech are serious, power also enables some speech. Power doesn’t just keep us from speaking—it also makes us speak. In this paper I explore how power produces, rather than constrains, speech. I discuss a kind of speech I call extracted speech: speech that is unjustly elicited from (...) an agent. I discuss examples of coerced confession, intimidated “consent,” and mandatory self-disclosure as instances of extracted speech, and theorize a bit about what significance this speech has more generally for philosophy of language and political philosophy.

How speech sounds are represented in the brain is not fully understood. The mismatch negativity (MMN) has proven to be a powerful tool in this regard. The MMN event-related potential is elicited by a deviant stimulus embedded within a series of repeating standard stimuli. Listeners construct auditory memory representations of these standards despite acoustic variability. In most designs that test speech sounds, however, this variation is typically intra-category: All standards belong to the same phonetic category. In the current paper, inter-category (...) variation is presented in the standards. These standards vary in manner of articulation but share a common phonetic feature. In the standard retroflex experimental block, Mandarin Chinese speaking participants are presented with a series of “standard” consonants that share the feature [retroflex], interrupted by infrequent non-retroflex deviants. In the non-retroflex standard experimental block, non-retroflex standards are interrupted by infrequent retroflex deviants. The within-block MMN was calculated, as was the identity MMN (iMMN) to account for intrinsic differences in responses to the stimuli. We only observed a within-block MMN to the non-retroflex deviant embedded in the standard retroflex block. This suggests that listeners extract [retroflex] despite significant inter-category variation. In the non-retroflex standard block, because there is little on which to base a coherent auditory memory representation, no within-block MMN was observed. The iMMN to the retroflex was observed in a late time-window at centro-parieto-occipital electrode sites instead of fronto-central electrodes, where the MMN is typically observed, potentially reflecting the increased difficulty posed by the added variation in the standards. In short, participants can construct auditory memory representations despite significant acoustic and inter-category phonological variation so long as a shared phonetic feature binds them together.

One of the themes that has been widely addressed in both the implicit learning and statistical learning literatures is that of rule learning. While it is widely agreed that the extraction of regularities from the environment is a fundamental facet of cognition, there is still debate about the nature of rule learning. Rey and colleagues show that the comparison between human and non‐human primates can contribute important insights to this debate.

We prove constructively that for any propositional formula in Conjunctive Normal Form, we can either find a satisfying assignment of true and false to its variables, or a refutation of showing that it is unsatisfiable. This refutation is a resolution proof of ¬. From the formalization of our proof in Coq, we extract Robinson’s famous resolution algorithm as a Haskell program correct by construction. The account is an example of the genre of highly readable formalized mathematics.

Connectionist networks excel at extracting statistical regularities but have trouble extracting higher-order relationships. Clark & Thornton suggest that a solution to this problem might come from Elman, but I argue that the success of Elman's single recurrent network is illusory, and show that it cannot in fact represent abstract relationships that can be generalized to novel instances, undermining Clark & Thornton 's key arguments.

This article describes the fight of transnational civic networks to influence business development strategies and counter the threats to environmental and labor rights posed by the construction and exploitation of the Baku-Tbilisi-Ceyhan (BTC) oil pipeline in Transcaucasia. The article starts by discussing the role of civil society in the global struggle for sustainable development. Then a brief overview of the geopolitical significance of the Transcaucasian-Caspian region in today’s oil and gas markets is presented. The case study looks at how the (...) actions of international and domestic nongovernmental organizations influenced the BTC’s main shareholder and operator company, British Petroleum, as well as host countries’ governments, to switch to more environmentally cognizant and socially responsive practices. The article discusses internationalization of civil society networks in response to the looming environmental crisis in the region, using the BTC case as an illustration. The article concludes by generalizing from this particular case study to the broader issue of transnational civic activism as a risk-mitigating factor in the world dominated by industry-related threats presented by globalization of the extractive technologies.

The applications and the (...) complexity of the created dynamic legislation network are also discussed and challenged. (shrink)

We ask what type of neutralization techniques corporations apply to allegations of human rights abuses. We proceed by undertaking a Qualitative Content Analysis of 162 responses by ten extractives-sector firms over a period of 14 years. The firms were responding to accusations of human rights impacts documented by the Business and Human Rights Resource Centre. We use Garrett et al.’s :507–520, 1989) framework of neutralization techniques consisting of denial, justification, concession and excuse to examine the responses. During our QCA, we (...) observed emerging themes around self-promotion and evasive tactics. We contribute to existing literature by proposing ‘evasion’ as a novel neutralization technique, particularly in circumstances of corporate responses to accusations of wrongdoing. We argue that evasion occurs when firms refuse to engage in the debate brought forward in an accusation. In addition, we enrich our understanding of neutralization techniques by proposing subneutralization techniques in our analysis to diverge from that of other studies. We conclude by discussing the implications of the predominance of corporate narcissism and evasive neutralization techniques to the business and human rights movement and other international corporate responsibility standards.

The combination of corporate-community conflicts and oil transnational corporations' (TNCs) rhetoric about being socially responsible has meant that the issue of community development and poverty reduction have recently moved from the periphery to the heart of strategic business thinking within the Nigerian oil industry. As a result, oil TNCs have increasingly responded to this challenge by adopting partnership strategies as a means to contribute to poverty reductions in their host communities as well as secure their social licence to operate. This (...) paper critically examines the strengths and weaknesses of the different community development partnership (CDPs) initiatives employed by Shell, Exxon Mobil and Total to contribute to poverty reduction within their host communities in the Niger Delta, Nigeria. Drawing on empirical data and critical analysis, the paper argues that while the CDP initiatives by SPDC, MPN and EPNL have the potential to contribute to community development, the failure to integrate negative injunction duties into existing partnerships means that the partnerships make no difference to how oil TNCs conduct their core business operation. Consequently, CDPs have had limited positive impact on poverty reduction in the Niger Delta. The paper concludes by examining the implications of the emerging issues for partnership and poverty reduction. (shrink)

Abstract.Carrying out a suggestion by Kreisel, we adapt Gödel’s functional interpretation to ordinary first-order predicate logic(PL) and thus devise an algorithm to extract Herbrand terms from PL-proofs. The extraction is carried out in an extension of PL to higher types. The algorithm consists of two main steps: first we extract a functional realizer, next we compute the β-normal-form of the realizer from which the Herbrand terms can be read off. Even though the extraction is carried out in the (...) extended language, the terms are ordinary PL-terms. In contrast to approaches to Herbrand’s theorem based on cut elimination orɛ-elimination this extraction technique is, except for the normalization step, of low polynomial complexity, fully modular and furthermore allows an analysis of the structure of the Herbrand terms, in the spirit of Kreisel ([13]), already prior to the normalization step. It is expected that the implementation of functional interpretation in Schwichtenberg’s MINLOG system can be adapted to yield an efficient Herbrand-term extraction tool. (shrink)

The possibility of extraction across awh-island is usually assumed to be dependent on whether or not the constituent in question can undergo “long” (i.e., nonlocal) Ā-movement across the island. However, the question of how to make a principled distinction between those elements which can violate locality and those which cannot is still rather controversial. I will propose that there are no well-formed locality violations in these cases, and that the grammaticality patterns observed derive from a semantic filter on the (...) escape hatch used to bypass the island. In other words, if a phrase is extracted across awh-island, it must adjoin to the island in order to get by. This adjunction site is restricted by the interpretive component: only traces which are interpreted as variables of typee can occur in this position, while higher-order variables are not allowed. This restriction is shown to capture the known facts aboutwh-island violations, as well as some less known phenomena, such as the absence of functional (and pair-list) readings acrosswh-islands.

In this paper, a novel approach for word extraction and character segmentation from the handwritten Bangla document images is reported. At first, a modified Run Length Smoothing Algorithm, called Spiral Run Length Smearing Algorithm, is applied for the extraction of words from the text lines of unconstrained handwritten Bangla document images. This technique has helped to overcome some of the drawbacks of standard horizontal and vertical RLSA techniques. SRLSA technique has been applied on the Bangla handwritten document image (...) database CMATERdb1.1.1 and the success rate of the word extraction is found to be 86.01%. In the second part of the work, we have presented a useful solution to the problem on how best word images of handwritten Bangla script can be segmented into constituent characters. Moreover, the technique can segment the words having discontinuity in Matra, a prominent feature of Bangla script. It also optimizes the trade-off between under/over segmentation as Matra region and segmentation points are estimated more precisely. As a result, better word segmentation accuracy is achieved with minimal data loss. Here, a success rate of 92.48% is observed on a dataset of 750 handwritten Bangla words which is 3.35% higher than that of our earlier techniques. (shrink)

The rapid increase in COVID-19 cases has become the symbol of fear, anxiety, and panic among people around the globe. Mass media has played an active role in community education by addressing the health information of this pandemic. People interact by sharing their ideas and feelings through social media platforms. There is a considerable need to implement different measures and better perceive COVID-19 pertinent facts and information by demystifying public sentiments. In this study, the Quarantine Life dataset of thousand tweets (...) is based on #Quarantine, #Quarantine Days, #Quarantine Life, #My Pandemic Plan, and #Quarantine and Chill from January to September 2020 has been collected from Twitter. The extracted data have been scrubbed through preprocessing techniques. The sentiments and topics extracted from tweets have been analyzed through the TEXT BLOB, VADER, and AFFIN approach. Results show that people were distressed and fearful due to the COVID-19 pandemic. However, most people enjoyed by playing games, watching movies, and reading books during the lockdown period. According to the present meta-analysis, physical activity interventions are beneficial for patients with dementia in terms of cognition. The proposed framework illustrates the insight impact of COVID-19 on human physiological and mainly focuses on the evaluation of sentiment dynamics at the topical level. (shrink)

A novel piecewise water flow technique for text line extraction from multi-skewed document images of handwritten text of different scripts is presented here. The basic water flow technique assumes that the hypothetical water flows from both left and right sides of the image frame. This flow of water fills up the gaps between consecutive objects but faces obstruction if any object lies in the path of the flow. All unwetted regions in the document image are then labeled distinctly to (...) extract the text lines. However, the technique fails when two neighboring text lines touch each other, as water gets obstructed by the touching segment. To get rid of this difficulty, we have modified the basic water flow technique by iteratively applying the same over the vertically segmented document images. The main purpose of this vertical segmentation is to localize the text line segment where two text lines get joined. These segments are then horizontally fragmented, and each fragment is placed suitably to the text line in which it actually belongs to. This way, the probable data loss during isolation of the touching text line segment is minimized. Both the techniques have been tested on three different databases, viz., CMATERdb 1.1.1, CMATERdb 1.1.2, and ICDAR2009 handwritten segmentation contest pages, respectively. The test results show that the present technique outperforms the basic one for all three databases. (shrink)

We describe research carried out as part of a text summarisation project for the legal domain for which we use a new XML corpus of judgments of the UK House of Lords. These judgments represent a particularly important part of public discourse due to the role that precedents play in English law. We present experimental results using a range of features and machine learning techniques for the task of predicting the rhetorical status of sentences and for the task of selecting (...) the most summary-worthy sentences from a document. Results for these components are encouraging as they achieve state-of-the-art accuracy using robust, automatically generated cue phrase information. Sample output from the system illustrates the potential of summarisation technology for legal information management systems and highlights the utility of our rhetorical annotation scheme as a model of legal discourse, which provides a clear means for structuring summaries and tailoring them to different types of users.

We report on an experiment examining whether individuals can solve a simple signal extraction problem of the type found in models with imperfect information. In one treatment, subjects must form point predictions based on observing both public and private signals, while in another they receive the same information but must decide on the weight to attach to each signal, which then determines their point prediction. We find that, at the aggregate level, signal extraction provides a good characterization of (...) subjects’ behavior in both treatments, but at the individual level, there is considerable heterogeneity in subjects’ ability to perform signal extraction.

Over the past two decades, researchers have made great advances in the area of computational methods for extracting meaning from text. This research has to a large extent been spurred by the development of latent semantic analysis (LSA), a method for extracting and representing the meaning of words using statistical computations applied to large corpora of text. Since the advent of LSA, researchers have developed and tested alternative statistical methods designed to detect and analyze meaning in text corpora. This research (...) exemplifies how statistical models of semantics play an important role in our understanding of cognition and contribute to the field of cognitive science. Importantly, these models afford large-scale representations of human knowledge and allow researchers to explore various questions regarding knowledge, discourse processing, text comprehension, and language. This topic includes the latest progress by the leading researchers in the endeavor to go beyond LSA. (shrink)
