Edible insects are a potentially less burdensome source of proteins on the environment than livestock for a majority of rural consumers. Hence, edible insects are a timely idea to address the challenges of the supply side to sustainably meet an increasing demand for food. The objective of this paper is twofold. The first is to identify and compare rural-households’ intentions to consume insect-based foods among households drawn from two regions in Kenya—one where consumption of insects is common and the other (...) where the practice is uncommon. The second is to explore consumers’ trust in sources of information regarding quality and appropriateness of food items. The study employed an extended theory of planned behaviour and involved 432 participants. Results indicate that rural households have positive intentions to consume insect-based foods and those intentions are higher for individuals who are more familiar with the practice. Results also show that information sources from industry are more trusted than those from the media. Further, the study revealed that control variables such as perceived availability of insect-based foods and their level of fit with the culinary practices have a higher influence on consumption intentions than general attitudes. In addition, age of the respondent, gender, household size and level of formal education, significantly influence the consumption intentions. The study discusses the implications of these findings in the development of sustainable agri-food systems. (shrink)

High-level perception--”the process of making sense of complex data at an abstract, conceptual level--”is fundamental to human cognition. Through high-level perception, chaotic environmen- tal stimuli are organized into the mental representations that are used throughout cognitive pro- cessing. Much work in traditional artificial intelligence has ignored the process of high-level perception, by starting with hand-coded representations. In this paper, we argue that this dis- missal of perceptual processes leads to distorted models of human cognition. We examine some existing artificial-intelligence models--”notably (...) BACON, a model of scientific discovery, and the Structure-Mapping Engine, a model of analogical thought--”and argue that these are flawed pre- cisely because they downplay the role of high-level perception. Further, we argue that perceptu- al processes cannot be separated from other cognitive processes even in principle, and therefore that traditional artificial-intelligence models cannot be defended by supposing the existence of a --œrepresentation module--� that supplies representations ready-made. Finally, we describe a model of high-level perception and analogical thought in which perceptual processing is integrated with analogical mapping, leading to the flexible build-up of representations appropriate to a given context.

A new edition of a comprehensive introduction to the philosophy of language, substantially updated and reorganized. The philosophy of language aims to answer a broad range of questions about the nature of language, including “what is a language?” and “what is the source of meaning?” This accessible comprehensive introduction to the philosophy of language begins with the most basic properties of language and only then proceeds to the phenomenon of meaning. The second edition has been significantly expanded and reorganized, putting (...) the original content in a contemporary context and offering substantial new material, with extended discussions and entirely new chapters. After establishing the basics, the book discusses general criteria for an adequate theory of meaning, takes a first pass at describing meaning at an abstract level, and distinguishes between meaning and other related phenomena. Building on this, the book then addresses various specific theories of meaning, beginning with early foundational theories and proceeding to more contemporary ones. New to this edition are expanded discussions of Chomsky's work and compositional semantics, among other topics, and new chapters on such subjects as propositions, Montague grammar, and contemporary theories of language. Each chapter has technical terms in bold, followed by definitions, and offers a list of main points and suggested further readings. The book is suitable for use in undergraduate courses in philosophy and linguistics. Some background in philosophy is assumed, but knowledge of philosophy of language is not necessary. (shrink)

In her article, Pascale Hess raises the issue of whether her proposed model may be extrapolated and applied to clinical research fields other than stem cell-based interventions in the brain (SCBI-B) (Hess 2012). Broadly summarized, Hess’s model suggests prioritizing efficacy over safety in phase 1 trials involving irreversible interventions in the brain, when clinical criteria meet the appropriate population suffering from “degenerative brain diseases” (Hess 2012). Although there is a need to reconsider the traditional phase 1 model, especially with respect (...) to first-in-human clinical trials involving novel technologies, the question arises as to whether it is appropriate to advocate for a new model that prioritizes efficacy over safety across all phase 1 clinical research trials involving irreversible interventions in the brain. -/- .

Applied ontologies have been used more and more frequently to enhance systems engineering. In this paper, we argue that adopting principles of ontological realism can increase the benefits that ontologies have already been shown to provide to the systems engineering process. Moreover, adopting Basic Formal Ontology (BFO), an ISO standard for top-level ontologies from which more domain specific ontologies are constructed, can lead to benefits in four distinct areas of systems engineering: (1) interoperability, (2) standardization, (3) testing, and (4) data (...) exploitation. Reaping these benefits in a model-based systems engineering (MBSE) context requires utilizing an ontology’s vocabulary when modeling systems and entities within those systems. If the chosen ontology abides by the principles of ontological realism, a semantic standard capable of uniting distinct domains, using BFO as a hub, can be leveraged to promote greater interoperability among systems. As interoperability and standardization increase, so does the ability to collect data during the testing and implementation of systems. These data can then be reasoned over by computational reasoners using the logical axioms within the ontology. This, in turn, generates new data that would have been impossible or too inefficient to generate without the aid of computational reasoners. (shrink)

Determining whether a research risk meets or exceeds a regulatory standard of risk acceptability is difficult. Recently a framework called the systematic evaluation of research risks (SERR) has been proposed as a method of comparing research risks with predetermined standards of acceptability. SERR purports to offer a systematic and largely determinate (definite) way to compare risks and say whether a specific research risk falls below or above an acknowledged standard of acceptable risk. Here the authors review some philosophical problems with (...) this framework, which they take to be representative of determinate approaches to risk comparison, and conclude that it should not be used in a stand-alone or determinate fashion. Instead, the authors suggest that a deliberative approach may be a more viable candidate for future development. Such an approach could be informed by methods such as SERR without being rigidly bound to them. (shrink)

Previous studies have documented the fallibility of attempts by surrogates and physicians to act in a substituted judgment capacity and predict end-of-life treatment decisions on behalf of patients. We previously reported that physicians misperceive their patients' preferences and substitute their own preferences for those of their patients with respect to four treatments: cardiopulmonary resuscitation in the event of cardiac arrest, ventilator for an indefinite period of time, medical nutrition and hydration for an indefinite period of time, and hospitalization in the (...) event of pneumonia.

The ability of adolescents to access safe and effective new products for HIV prevention and treatment is optimised by adolescent licensure at the same time these products are approved and marketed for adults. Many adolescent product development programmes for HIV prevention or treatment products may proceed simultaneously with adult phase III development programmes. Appropriately implemented, this strategy is not expected to delay licensure as information regarding product efficacy can often be extrapolated from adults to adolescents, and pharmacokinetic properties of drugs (...) in adolescents are expected to be similar to those in adults. Finally, adolescents enrolled in therapeutic HIV prevention and treatment research can be considered adults, based on US Food and Drug Administration regulations and the appropriate application of state law. The FDA permits local jurisdictions to apply state and local HIV/sexually transmitted infection minor treatment laws so that adolescents who are HIV-positive or at risk of contracting HIV may be enrolled in therapeutic or prevention trials without obtaining parental permission.

Cognitive neuroscience aims to map mental processes onto brain function, which begs the question of what “mental processes” exist and how they relate to the tasks that are used to manipulate and measure them. This topic has been addressed informally in prior work, but we propose that cumulative progress in cognitive neuroscience requires a more systematic approach to representing the mental entities that are being mapped to brain function and the tasks used to manipulate and measure mental processes. We describe (...) a new open collaborative project that aims to provide a knowledge base for cognitive neuroscience, called the Cognitive Atlas, and outline how this project has the potential to drive novel discoveries about both mind and brain.

The most striking example of Roman intervention in the affairs of mainland Greece between the Achaean and Mithridatic Wars is provided by an inscription now in the Fitzwilliam Museum, Cambridge. This stone bears the text of a letter to the city of Dyme in Achaea from a Roman proconsul named Q. Fabius Maximus, which describes his trial and sentencing of certain men of Dyme whom he had judged responsible for a recent disturbance in that city. One crux to be resolved (...) is chronological: A date of c. 115 b.c. has long been generally accepted, but recently evidence from another, still unpublished inscription has been thought to point to the year 144. Further, the letter of Fabius Maximus has long been held to exemplify the close supervision that most scholars, regardless of their position on the vexed question of Greece's formal status after 146, assume was exercised over Greece by Roman commanders in Macedonia from the time of the Achaean War. The document has also often been cited to bolster the claim that Rome pursued in second-century Greece a conscious policy of suppressing democracy or the political aspirations of the lower class. This is not, of course, the place for reassessment of these old, complex controversies. My purpose here is rather to show that interpretation of the letter of Fabius Maximus has not always been sufficiently mindful of the many obscurities of the text and, consequently, of the events that lie behind it; too often the great lacunae in our knowledge have been filled with assumptions that beg the questions that are under debate.

Whilst the role of Maturation or M‐phase Promoting Factor (MPF) as a universal M‐phase regulator is well documented, much less attention has been paid to its role in nuclear transplantation experiments and especially to its influence upon remodelling of transplanted nuclei. There is currently wide acceptance that successful nuclear transplantation using differentiated nuclei is possible only in a cytoplasmic environment that is capable of inducing rapid nuclear de‐differentiation to a pronuclear‐like form. In this review our purpose is firstly, to outline (...) the conditions under which such remodelling can be induced, and secondly, to extend the debate to include a consideration of whether complete nuclear remodelling is an absolute necessity for clonal development.

In its October 2001 issue, this journal published a series of articles questioning the Whole-Brain-based definition of death. Much of the concern focused on whether somatic integration - a commonly understood basis for the whole-brain death view - can survive the brain's death. The present article accepts that there are insurmountable problems with whole-brain death views, but challenges the assumption that loss of somatic integration is the proper basis for pronouncing death. It examines three major themes. First, it accepts the (...) claim of the "disaggregators" that some behaviors traditionally associated with death can be unbundled, but argues that other behaviors (including organ procurement) must continue to be associated. Second, it rejects the claims of the "somaticists," that the integration of the body is critical, arguing instead for equating death with the irreversible loss of "embodied consciousness," that is, the loss of integration of bodily and mental function. Third, it defends higher-brain views against the charge that they are necessarily "mentalist," that is, that they equate death with losing some mental function such as consciousness or personhood. It argues, instead, for the integration of bodily and mental function as the critical feature of human life and that its irreversible loss constitutes death. (shrink)

How did meat emerge to become such an important feature in Western society? In both popular and academic literatures, biophysical and political-economic factors are often cited as the reason for meat’s preeminent status. In this paper, we perform a comprehensive investigation of these claims by reviewing the available evidence on the political-economic and biophysical features of meat over the long arc of Western history. We specifically focus on nine critical epochs: the Paleolithic, early to late Neolithic, antiquity, ancient Israel and (...) early Christian societies, medieval Europe, early modern Europe, colonial America, the American frontier, and the modern industrial era. We find that except under conditions of environmental scarcity, the meaning and value of meat cannot be attributed to intrinsic biophysical value or to the political-economic actors who materially benefit from it. Rather, meat’s status reflects the myriad cultural contexts in which it is socially constructed in people’s everyday lives, particularly with respect to religious, gender, communal, racial, national, and class identity. By deconstructing the normalized/naturalized materialist assumptions circling around meat consumption, this paper clears a space for a more nuanced appreciation of the role that culture has played in the legitimation of meat, and by extension, the possibility of change.

When The Ad Hoc Committee of Harvard Medical School to Examine the Definition of Brain Death began meeting in 1967, I was a graduate student, with committee member Ralph Potter and committee chair Henry Beecher as my mentors. The question of when to stop life support on a severely compromised patient was not clearly differentiated from the question of when someone was dead. A serious clinical problem arose when physicians realized that a patient's condition was hopeless but life support perpetuated (...) body function. Thus, the committee stated that its first purpose was to deal with the burdens on patients and families as well as on hospitals and on patients needing hospital beds occupied by comatose patients. They intuited the strategy of “defining” these patients as dead, thus legitimating treatment stoppage. They noted that this would also serve a second purpose. Although the dead donor rule had not yet been clearly articulated, they claimed that defining patients as dead would also address controversy over obtaining organs for transplant.My mentors’ discussions related to my interest in the intersection between questions primarily of medical fact (When has a human brain irreversibly ceased functioning?) and nonmedical questions of social policy (Should we treat individuals with dead brains and beating hearts as dead humans?). It quickly became clear that most committee members did not appreciate the interplay of these questions. (shrink)

No one really believes that literally all functions of the entire brain must be lost for an individual to be dead. A better definition of death involves a higher brain orientation.

Clinicians cannot obtain valid consent to treatment because they cannot guess which treatment option will serve a particular patient's best interests. These guesses could be made more accurately if patients were paired with providers who share their deep values.
