Culinary traditions and food practices are at the center of our daily lives and therefore constitute an important part of culture. Whether they are part of significant rituals or simply routinely enacted, they tell us something about the way we relate to each other and to the non-human world. In other words, food practices have an ethical dimension. Our paper focuses on the possibility to make objective ethical assessments of problematic cultural practices rooted in culinary traditions as a reply to (...) arguments associated with an ethical relativism according to which cultures produce ethical systems that are self-validating and therefore that cannot be criticized objectively. Drawing from examples involving animal cruelty and production methods harmful to the environment, we argue that it is possible to judge ethically questionable food practices from an objectivist standpoint inspired by moral progress, in contrario to a relativist point of view. Following a short discussion of ethical relativism, we present the outline of an acceptability test for questionable food practices and use it to analyse the case of the dog meat industry in South Korea.

France, a country with nearly 66 million inhabitants, contributed greatly to the construction of the European Union as one of the founder states. In 1957, the treaties establishing the European Economic Community and the European Atomic Energy Community were signed by Belgium, France, Germany, Italy, Luxembourg, and the Netherlands in Rome. Today, they are referred to as the “Treaties of Rome.” The French contribution to the EU has strongly influenced the political views on the development of Europe, notably pushing for (...) a large contribution of member states to the decision making processes and to the orientation of the EU policies.

During the afternoon of December 21, 1989, in Bucharest, a mass of demonstrators gather in a public square at the request of Nicolae Ceausescu, then president of Romania. In the previous days, students had shaken the country by taking to the streets in protest in the city of Timisoara. These mass protests had been preceded that year by a wave of other social movements that took place in Poland, Hungary, East Germany, Bulgaria, and Czechoslovakia. Now in a broadcast from the (...) balcony of the square, Ceausescu tries to reassure the population while making distressed appeals to preserve the unity of the political regime in the country. In the front row of the assembled crowd... (shrink)

The development of the aquaculture industry in Canada has triggered a conflict of a scope never seen before. As stated in Young and Matthews’ The Aquaculture Controversy, this debate has “mushroomed over the past several decades to become one of the most bitter and stubborn face-offs over industrial development ever witnessed in Canada” (Young and Matthews in The aquaculture controversy in Canada. Activism, policy and contested science. UBC Press, Vancouver, p 3, 2010). It opposes a wide variety of actors: from (...) industrial investors, scientists, politicians and environmentalists to Native associations and communities, citizens groups and local stakeholders. The opposition is fierce between those in favor of a flourishing and modern aquaculture of industrial nature and those who fear the dreadful consequences of such an industry. In particular, the possible implementation of biotechnology innovations, such as a genetically modified salmon, has made this debate coextensive with the GMO debate, thus multiplying the opposition’s spectrum of arguments against the industry. Throughout the debate, Canadian environmental NGOs like the Suzuki Foundation and Greenpeace Canada have assumed leadership over the opposition to aquaculture development with certain success. Their participation in the debate features numerous ethical concerns related to environmental health, a respect for wilderness and local human communities. Such a position can be associated overall with a form of ecocentric ethics or concern. Nevertheless, a careful examination of the technical solutions proposed by these NGOs reveals their embeddedness in biocentrism. Through the example taken from the Canadian debate on aquaculture development, this paper aims to highlight the conceptual difficulty of enacting ecocentric ethical positions beyond formal arguments. Because ecocentrism implies a true paradigm shift, not only in mentality, but also in the way we conceive our technical interventions in nature, biocentrism remains an important practical method to enact ethical positions related to environmental concerns in public debates.

The ambiguous-cue task is composed of two-choice simultaneous discriminations involving three stimuli: positive (P), ambiguous (A) and negative (N). Two different trial types are presented: PA and NA. The ambiguous cue (A) served as an S- in PA trials, but as an S+ in NA trials. When using this procedure, it is typical to observe a less accurate performance in PA trials than in NA trials. This is called the ambiguous-cue effect. Recently, it was reported in starlings that the ambiguous-cue (...) effect decreases when the stimuli are presented on an angled (120°) panel. The hypothesis is that the angled panel facilitates that the two cues from each discrimination are perceived as a compound, precluding value transfer via a second-order conditioning mechanism. In this experiment, we used pigeons and a flat panel. Nevertheless, our data were quite similar to the previous data in starlings. We conclude that the form of the panel cannot explain the ambiguous-cue effect. Several alternatives to be explored in future experiments are suggested. The riddle of the ambiguous-cue problem still remains unsolved. (shrink)

The article is devoted to the symbolics of doves on epigraphic embroidered towels (mainly known as rushnyks with inscriptions), which were massively produced by Ukrainian girls and women from the end of the nineteenth till the middle of the twentieth century. Embroidering lines from folk songs or proverbs on textile was a very popular kind of so-called written (or fixed) folklore. By combining these verbal texts with different images of pigeons, fundamentally new works were created. For some time, this (...) phenomenon was almost forgotten. However, in the course of recent years Ukrainian collectors and artists have been actively using old embroidered samples for souvenir products or stage decorations. Being popularized and updated in our time, the meaning of these embroidered birds has undergone significant changes. On specific examples, the author shows how one and the same image of pigeons acquires different, often even opposite senses depending on the context. (shrink)

There is a dearth of academic research on the ethics of pigeon racing. We argue that pigeon racing is associated with significant benefits and disadvantages, but that the benefits that have been associated with it can be provided by alternative practices. Disadvantages include the competitive element associated with racing, which creates a strong incentive to kill birds where this is not in their best interests, as well as the welfare issues related to transportation, the widowhood system, the races themselves, and (...) the use of performance-enhancing drugs. Whilst some of these disadvantages can be diminished, we argue that an ethical form of pigeon racing is not possible, and that it therefore ought to be prohibited. In the final part of this article, we question whether the moral problems associated with pigeon racing include the keeping of pigeons per se. On this issue, we argue that keeping pigeons does pose moral problems, but that more research is needed to explore whether these might be relatively minor compared to the problems associated with de-domesticating pigeons. The moral implications of our research extend beyond the world of pigeon racing as similar arguments should be used to question the racing and keeping of many other animals. (shrink)

Spontaneous mirror self-recognition is achieved by only a limited number of species, suggesting a sharp “cognitive Rubicon” that only few can pass. But is the demarcation line that sharp? In studies on monkeys, who do not recognize themselves in a mirror, animals can make a difference between their mirror image and an unknown conspecific. This evidence speaks for a gradualist view of mirror self-recognition. We hypothesize that such a gradual process possibly consists of at least two independent aptitudes, the ability (...) to detect synchronicity between self- and foreign movement and the cognitive understanding that the mirror reflection is oneself. Pigeons are known to achieve the first but fail at the second aptitude. We therefore expected them to treat their mirror image differently from an unknown pigeon, without being able to understand that the mirror reflects their own image. We tested pigeons in a task where they either approached a mirror or a Plexiglas barrier to feed. Behind the Plexiglas an unknown pigeon walked at the same time toward the food bowl. Thus, we pitched a condition with a mirror-self and a foreign bird against each other, with both of them walking close toward the food bowl. By a detailed analysis of a whole suit of behavioral details, our results make it likely that the foreign pigeon was treated as a competitor while the mirror image caused hesitation as if being an uncanny conspecific. Our results are akin to those with monkeys and show that pigeons do not equal their mirror reflection with a conspecific, although being unable to recognize themselves in the mirror. (shrink)

The pigeon-inspired optimization algorithm is a category of a newly proposed swarm intelligence-based algorithm that belongs to the population-based solution technique. The MKP is a class of complex optimization problems that have many practical applications in the fields of engineering and sciences. Due to the practical applications of MKP, numerous algorithmic-based methods like local search and population-based search algorithms have been proposed to solve the MKP in the past few decades. This paper proposes a modified binary pigeon-inspired optimization algorithm named (...) (Modified-BPIO) for the 0 - 1 multidimensional knapsack problem (MKP). The utilization of the binary pigeon-inspired optimization (BPIO) for solving the multidimensional knapsack problem came with huge success. However, it can be observed that the BPIO converges prematurely due to lost diversity during the search activities. Given the above, the crossover operator is integrated with the landmark component of the BPIO to improve the diversity of the solution space. The MKP benchmarks from the Operations Research (OR) library are utilized to test the performance of the proposed binary method. Experimentally, it is concluded that the proposed Modified-BPIO has a better performance when compared with the BPIO and existing state-of-the-arts that worked on the same MKP benchmarks. (shrink)

The target authors make a strong case for parallels between human and nonhuman metacognition. The case may be bolstered by an appeal to the literatures on commitment and self-control and to that on observing behavior.

In addition to their historical interest, cultural heritage buildings are valuable because they contribute significantly to the economy by providing key attractions at a time when tourism and leisure are major industries. The need for preserving historical constructions is thus not only a cultural requirement, but also an economical and developmental demand. Herein, among different Iranian heritage buildings, pigeon towers, or dovecotes, are of a great importance. Hundreds of dovecotes, dating largely to the Safavid period, dot the fields in the vicinity of Isfahan. On the other hand, valleys formed by creeks in central parts of Anatolia seem to have offered suitable environments for ancient settlements. Cappadocia region and two valleys nearby the town of Gesi accommodate a number of villages surrounded by hundreds of dove cotes in different types. This paper investigates different types of dovecotes in Iran plateau and Central Anatolia, Turkey. The results show there is a fundamental difference between the structures of dovecotes in these two countries. However, ancient dovecotes in Iran and Central Anatolia can be considered good examples of 'architecture without architects' or ' spectacular vernacular architecture'. Master builders who designed and constructed these buildings for such a simple function, created impressive forms without much pretension and bringing forth the tectonic aspects of the art of architecture.

Battery energy storage is the pivotal project of renewable energy systems reform and an effective regulator of energy flow. Parallel battery packs can effectively increase the capacity of battery modules. However, the power loss caused by the uncertainty of parallel battery branch current poses severe challenge to the economy and safety of electric vehicles. Accuracy of battery branch current prediction is needed to improve the parallel connection. This paper proposes a radial basis function neural network model based on the pigeon-inspired (...) optimization method and successfully applies the algorithm to predict the parallel branch current of the battery pack. Numerical results demonstrate the high accuracy of the proposed pigeon-inspired optimized RBF model for parallel battery branch forecasting and provide a useful tool for the prediction of parallel branch currents of battery packs.

The harvest and the pigeons. A note on the summit course of the pillar of Prusias at Delphi The remains of the pillar of Prusias, next to the temple of Apollon at Delphi, have generated much comment. Indeed, the course that supported the equestrian statue of the king of Bithynia presents 112 mortises, above and beyond the attachment holes of the statue itself. Until the present, it has been thought that these cavities served to attach vegetal elements, ears of (...) corn reaped by a laborer or, after the identification of the base as belonging to the pillar of Prusias, a field of corn signifying the beneficence of the king. A trail of textual and archaeological indications prompts a different interpretation for this enigmatic arrangement. The mortises would have served the insertion of bronze points (obeloi or meniskoi) forming a system of protection against defacement by birds, as is occasionally the case in sculpture and in temple architecture.

In this article I bring together Jacques Derrida and Luce Irigaray's engagements with Sigmund Freud's vexed attempt to step beyond the pleasure principle. Derrida's speculations on the name, the house and the practice of Freud find him inadvertently rewriting the conditions of the autobiographical as that which erases as much as inscribes, while Irigaray requires a sexually different modelling of what we call language if the experience of the girl is to be addressed. Yet Irigaray uncannily repeats the teleological gesture (...) of laying claim to a legacy, diagnosed in Freud by Derrida, even as this legacy is newly imagined as that of the feminine to which Freud remained blind. I then interweave these revised stakes of the fort-da game as they are expressed in two experimental films; Lynn Hershman Leeson's feature Conceiving Ada (USA, 1997) and Hussein Chalayan's short Absent Presence (UK/Turkey, 2005). One self-consciously concerns the recovery of ‘lost’ women from history (da!), the other investigates the treatment of the foreigner staged with an all-female cast (in which the instability of foreign objects can secure no fortification for the scientific subject). The films differently engage fantasies concerning genetics, and differently engage the projection of a legacy as teleological ambition. Privileging Derrida's transformation of the pleasure into the postal principle as that which invokes ‘Tele–without telos’, I ask after the transmissibility of this ambition. (shrink)

Over many centuries, the homing pigeon has been selectively bred for returning home from a distant location. As a result of this strong selective pressure, homing pigeons have developed an excellent spatial navigation system. This system passes through the hippocampal formation, which shares many striking similarities to the mammalian hippocampus; there are a host of shared neuropeptides, interconnections, and its role in the storage and manipulation of spatial maps. There are some notable differences as well: there are unique connectivity (...) patterns and spatial encoding strategies. This review summarizes the comparisons between the avian and mammalian hippocampal systems, and the responses of single neurons in several general categories: location and place cells responding in specific areas, path and goal cells responding between goal locations, context-dependent cells that respond before or during a task, and pattern, grid, and boundary cells that increase firing at stable intervals. Head-direction cells, responding to a specific compass direction, are found in mammals and other birds but not to date in pigeons. By studying an animal that evolved under significant adaptive pressure to quickly develop a complex and efficient spatial memory system, we may better understand the comparative neurology of neurospatial systems, and plot new and potentially fruitful avenues of comparative research in the future.

The analogy between artificial selection of domestic varieties and natural selection in nature was a vital element of Darwin's argument in his Origin of Species. Ever since, the image of breeders creating new varieties by artificial selection has served as a convincing illustration of how the theory works. In this paper I argue that we need to reconsider our understanding of Darwin's analogy. Contrary to what is often assumed, nineteenth-century animal breeding practices constituted a highly controversial field that was fraught (...) with difficulties. It was only with considerable effort that Darwin forged his analogy, and he only succeeded by downplaying the importance of two other breeding techniques - crossing of varieties and inbreeding - that many breeders deemed essential to obtain new varieties. Part of the explanation for Darwin's gloss on breeding practices, I shall argue, was that the methods of his main informants, the breeders of fancy pigeons, were not representative of what went on in the breeding world at large. Darwin seems to have been eager to take the pigeon fanciers at their word, however, as it was only their methods that provided him with the perfect analogy with natural selection. Thus while his studies of domestic varieties were important for the development of the concept of natural selection, the reverse was also true: Darwin's comprehension of breeding practices was moulded by his understanding of the working of natural selection in nature. Historical studies of domestic breeding practices in the eighteenth and nineteenth century confirm that, besides selection, the techniques of inbreeding and crossing were much more important than Darwin's interpretation allowed for. And they still are today. This calls for a reconsideration of the pedagogic use of Darwin's analogy too. (shrink)

For each $p \geq 2$ there exists a model ${\bf M}^{*}$ of $I\Delta_{0}(\alpha)$ which satisfies the Count( $p$ ) principle. Furthermore, if $p$ contains all prime factors of $q$ there exist $n,r \in {\bf M}^{*}$ and a bijective map $f \in {\rm dom}({\bf M}^{*})$ mapping $\{1,2,\ldots,n\}$ onto $\{1,2,\ldo ts,n+q^{r}\}$ . A corollary is a complete classification of the Count( $q$ ) versus Count( $p$ ) problem. Another corollary shows that the pigeon-hole principle for injective maps does not follow from any (...) of the Count( $q$ ) principles. This solves an open question [Ajtai 94]. (shrink)

and was correct to conclude that the way a biological population is described should affect conclusions about whether natural selection occurs, but wrong to conclude that natural selection is therefore not a cause. After providing a new argument that ignored crucial biological details, I give a biological illustration that motivates a fairly extreme dependence on description. I argue that contrary to an implication of , biologists allow much flexibility in describing populations, as contemporary research on recent human evolution shows. Properly (...) understood, such description-dependence is consistent with descriptions capturing different causal relations involving the same population. I thus show that Walsh’s arguments fail for reasons that have not previously been understood; I argue that Walsh’s more recent “Sure Thing” argument fails for similar reasons. The resulting view provides a new perspective on causation in evolutionary processes. (shrink)

The current study examined whether pigeons could learn to use abstract concepts as the basis for conditionally switching behavior as a function of time. Using a mid-session reversal task, experienced pigeons were trained to switch from matching-to-sample (MTS) to non-matching-to-sample (NMTS) conditional discriminations within a session. One group had prior training with MTS, while the other had prior training with NMTS. Over training, stimulus set size was progressively doubled from 3 to 6 to 12 stimuli to promote abstract (...) concept development. Prior experience had an effect on the initial learning at each of the set sizes but by the end of training there were no group differences, as both groups showed similar within-session linear matching functions. After acquiring the 12-item set, abstract-concept learning was tested by placing novel stimuli at the beginning and end of a test session. Prior matching and non-matching experience affected transfer behavior. The matching experienced group transferred to novel stimuli in both the matching and non-matching portion of the sessions using a matching rule. The non-matching experienced group transferred to novel stimuli in both portions of the session using a non-matching rule. The representations used as the basis for mid-session reversal of the conditional discrimination behaviors and subsequent transfer behavior appears to have different temporal sources. The implications for the flexibility and organization of complex behaviors are considered. (shrink)

The Generality Constraint is a condition discussed by Gareth Evans that is meant to distinguish candidate subjects into those who have conscious thought of the type needed for a neo-Fregean conception of an objective world and those who are not subjects of that type. I argue that it implicitly applies to free-ranging creatures in a world of objects that they perceive and on which they act. This is quite unlike the behaviour exhibited by pigeons who attempt to maximise rewards (...) in a limited operant response situation where those rewards are indexed to particular numbers of key pecks as the ability needed to master that task is not the kind of thing Evans is interested in and it can be explained much more parsimoniously.

We study the complexity of proving the Pigeon Hole Principle in a monotone variant of the Gentzen Calculus, also known as Geometric Logic. We prove a size-depth trade-off upper bound for monotone proofs of the standard encoding of the PHP as a monotone sequent. At one extreme of the trade-off we get quasipolynomia -size monotone proofs, and at the other extreme we get subexponential-size bounded-depth monotone proofs. This result is a consequence of deriving the basic properties of certain monotone formulas (...) computing the Boolean threshold functions. We also consider the monotone sequent expressing the Clique-Coclique Principle defined by Bonet, Pitassi and Raz [9]. We show that monotone proofs for this sequent can be easily reduced to monotone proofs of the one-to-one and onto PHP, and so CLIQUE also has quasipolynomia -size monotone proofs. As a consequence of our results, Resolution, Cutting Planes with polynomially bounded coefficients, and Bounded-Depth Frege are exponentially separated from the monotone Gentzen Calculus. Finally, a simple simulation argument implies that these results extend to the Intuitionistic Gentzen Calculus. Our results partially answer some questions left open by P. Pudlák. (shrink)

The hypothesis proposed by Macphail is that differences in intelligent behavior thought to distinguish different species were likely attributed to differences in the context of the tasks being used. Once one corrects for differences in sensory input, motor output, and incentive, it is likely that all vertebrate animals have comparable intellectual abilities. In the present article I suggest a number of tests of this hypothesis with pigeons. In each case, the evidence suggests that either there is evidence for the (...) cognitive behavior, or the pigeons suffer from biases similar to those of humans. Thus, Macphail’s hypothesis offers a challenge to researchers to find the appropriate conditions to bring out in the animal the cognitive ability being tested. (shrink)

There is much hype around the idea of bringing the Passenger Pigeon back from extinction. However, ‘de-extinction’ is a fantasy that is not grounded in science. The proposed plans for ‘de-extinction’ would create a new organism that is not likely to be viable in the wild. Thus, ‘de-extinction’ as proposed is unethical both because it could lead into the release in nature of a new genetically created organism and because it is not honest to claim that it would reverse the (...) extinction of the Passenger Pigeon.
