Sagoff [Journal of Agricultural and Environmental Ethics 18 (2005), 215–236] argues, against growing empirical evidence, that major environmental impacts of non-native species are unproven. However, many such impacts, including extinctions of both island and continental species, have both been demonstrated and judged by the public to be harmful. Although more public attention has been focused on non-native animals than non-native plants, the latter more often cause ecosystem-wide impacts. Increased regulation of introduction of non-native (...) class='Hi'>species is, therefore, warranted, and, contra Sagoff’s assertions, invasion biologists have recently developed methods that greatly aid prediction of which introduced species will harm the environment and thus enable more efficient regulation. The fact that introduced species may increase local biodiversity in certain instances has not been shown to result in desired changes in ecosystem function. In other locales, they decrease biodiversity, as they do globally. (shrink)

Conservation biologists and other environmentalists confront five obstacles in building support for regulatory policies that seek to exclude or remove introduced plants and other non-native species that threaten to harm natural areas or the natural environment. First, the concept of “harm to the natural environment” is nebulous and undefined. Second, ecologists cannot predict how introduced species will behave in natural ecosystems. If biologists cannot define “harm” or predict the behavior of introduced species, they must target all (...) non-native species as potentially “harmful”. an impossibly large regulatory task. Third, loss of species richness may constitute harm to an environment, but introduced organisms typically, generally, and significantly add to species richness in ecosystems. If species richness correlates with desirable ecosystem properties, moreover, such as stability and productivity, as some ecologists believe, then introduced organisms, by increasing species richness, would support those desirable properties. Fourth, one may plausibly argue that extinction constitutes environmental harm, but there is no evidence that non-native species, especially plants, are significant causes of extinction, except for predators in certain lakes and other small island-like environments. Fifth, while aesthetic, ethical, and spiritual values may provide a legitimate basis for invasive species policy, biologists often cite concepts such as “biodiversity” and ecosystem “health” or “integrity” to provide a scientific justification. To assert that non-native species threaten biodiversity or undermine ecosystem health, however, may be to draw conceptual entailments or consequences from definitions of “biodiversity” and “integrity” that arbitrarily exclude non-native species or make the presence of exotic species a per se indicator of decline.

Metaphors for describing the introduction, impacts, and management of non-native species are numerous and often quite outspoken. Policy-makers have adopted increasingly disputed metaphorical terms from scientific discourse. We performed a critical analysis of the use of strong metaphors in reporting scientific findings to policy-makers. Our analysis shows that perceptions of harm, invasiveness or nativeness are dynamic and inevitably display multiple narratives in science, policy or management. Improving our awareness of multiple expert and stakeholder narratives that exist in the (...) context of non-native species management, as well as metaphorical alternatives, is critical. (shrink)

Species are ordinarily conceived of as being native or non-native to either a geographical location or an ecological community. I submit that species may also be native or non-native to human communities. I argue, by way of an analogy with varieties of domesticated and cultivated species, that this sense of nativity is grounded by the cultural relationships human communities have with species. A further analogy is drawn with the motivations of varietal nativists (...) – who seek to protect native varieties of domesticated and cultivated species for the sake of their cultural value – to argue for the consideration of the cultural value of native species in environmental policy decisions regarding invasive non-native species. (shrink)

The keystone species concept is often used in conservation. However, scientists and conservationists use the concept in many different ways. I suggest that a problem with the concept in conservation is not the lack of a shared definition. Instead, the problem is how the concept is applied to only certain species despite potentially covering a broader suite of species. This highlights unstated values in using the concept in conservation. I use novel examples, such as non-native Burmese (...) pythons in Florida, to motivate this. I argue that the concept should include these species and be used value-neutral. (shrink)

Neobiota as non-native species are commonly considered as alien species. The Convention on Biological Diversity (CBD) intends to “prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats or species”. The European Union has financed the DAISIE research project for the first pan-European inventory of Invasive Alien Species (IAS), which is supposed to serve as a basis for prevention and control of biological invasions. This paper discusses the evaluation approach for (...) classifying “100 of the Worst” IAS in Europe by the EU DAISIE research project. The main impact categories used by DAISIE for assorting “100 of the Worst” IAS are investigated and the texts of the “Wanted” species factsheets are examined. Two examples from the DAISIE factsheets of the “100 of the Worst” IAS [Tree of Heaven ( Ailanthus altissima ) and the Raccoon ( Procyon lotor )] are discussed to illustrate DAISIE’s biodiversity evaluation approach in more detail. However, the classification criteria used by DAISIE do not allow for sufficiently differentiating these neobiota from an ecological behavior of native species with a similar ecological niche. In conclusion, neobiota evaluations are not comprehensive when they refer mainly to the successful expansion and competition with native species into available ecological niches. A comprehensive assessment of the impacts of neobiota on biodiversity and humans needs to take into account the different values of biodiversity as mentioned in the preamble of the CBD. (shrink)

Within the last 20 years, the US has mounted amassive campaign against invasions bynon-indigenous species (NIS) such as zebramussels, kudzu, water hyacinths, and brown treesnakes. NIS have disrupted native ecosystemsand caused hundreds of billions of dollars ofannual damage. Many in the scientificcommunity say the problem of NIS is primarilypolitical and economic: getting governments toregulate powerful vested interests thatintroduce species through such vehicles asships' ballast water. This paper argues that,although politics and economics play a role,the problem is primarily (...) one of scientificmethod. Even if commercial interests werewilling to spend the necessary funds to controlNIS, and even if government were willing toregulate them, ecological theory is notadequate to provide clear direction for eithereffort. The paper argues there is nocomprehensive, predictive theory ofinvasibility, as part of a larger theory ofcommunity structure, that might guideecological decision making regarding NIS, andfor at least three reasons. (1) There is nofirm definition of NIS, native, exotic,and so on, and ecologists do not use the termsconsistently; as a result, biologists debatingvarious accounts of community structure andecological explanation often do not even makelogical contact with each other. (2) Thedominant theory used to understandinvasibility, island biogeography, has noprecise predictive power and is unable toclarify when NIS might promote biodiversity andwhen they might hinder it. (3) There are nofirm, empirical generalizations that revealwhen a colonizer or a NIS might be likely totake over a new environment, and when it mightnot succeed in doing so. As a result,scientists have only rough rules of thumb toshore up their arguments against NIS. Given theincompleteness of current ecological theory,the paper closes with several suggestions forways that study of NIS might enhanceunderstanding of basic commmunity structuresand vice versa.

Non-native species are implicated in many ecological and economic problems, and the field of invasion biology has burgeoned in response to this fact. However, classification, terminology, and management of non-native species generate controversies and even calls for abolition of the field. The fact that the basis for disputes is differing worldviews rather than simply interpretation of biological observations suggests that resolving arguments about non-native species will be difficult, independently of questions about the operational tractability (...) of proposed courses of action.

It is common for conservationists to refer to non-native species that have undesirable impacts on humans as “invasive”. We argue that the classification of any species as “invasive” constitutes wrongful discrimination. Moreover, we argue that its being wrong to categorize a species as invasive is perfectly compatible with it being morally permissible to kill animals—assuming that conservationists “kill equally”. It simply is not compatible with the double standard that conservationists tend to employ in their decisions about (...) who lives and who dies. (shrink)

This paper argues that the occurrence of a non-native species, such as purple loosestrife, on one's property does not constitute a nuisance in the context of background principles of common law. No one is injured by it. The control of non-native species, such as purple loosestrife, does not constitute a compelling public interest, moreover, but represents primarily the concern of an epistemic community of conservation biologists and ecologists. This paper describes a history of cases in agricultural (...) law that establish that a public authority may enter private property to destroy a tree or other species but only to protect a compelling public interest, such as the apple industry in Virginia or the citrus industry in Florida, and only if it pays all the costs including just compensation. The paper argues a fortiori that if a public authority enters private property to control non-native or “invasive” species it must pay all the costs and indemnify the owner—contrary to what many state laws contemplate and the Environmental Law Institute recommends.

In this essay, I discuss the comparison between the restoration of natural environments and the Nazi project to develop a pure homeland for native species and authentic Aryan humans. There exists a metaphorical comparison between Nazi eliminationist policies regarding specific human populations and the eradication of invasive and non-native species in ecological restorations. Moreover, there are substantive environmental policies of the Nazi regime that appear to be similar to the goals and methodology of contemporary restoration practice. (...) But there is also a more fundamental connection: the idea of the domination of the natural world. The idea of domination is the key to understanding both the process of ecological restoration and its real connection to Nazism. (shrink)

Many aquatic invasive species (AIS) management programs are doing important work on preventing non-indigenous species movement to our wild places. Attitudes and perspectives on aquatic non-indigenous species and their management by ecologists and the public are fundamentally a question of human values. Despite eloquent philosophical writings on treatment of non-indigenous species, management agency rhetoric on ‘invasive’ species usually degenerates to a good versus evil language, often with questionable results and lost conservation dollars. We assess and (...) learn from an established AIS program. We discuss an ethic framework and operational directives to minimise the trap of a binary classification of species into bad or good, and we advocate for a principled pragmatic approach to minimise conflicts. We make a case for not labelling species and instead focusing on managing nuisance conditions and protecting ecosystem health. (shrink)

In their fine paper, Evans et al. discuss the proposition that invasive non-native species are harmful. The question to ask is, “Harmful to whom?” Pathogens that make people sick and pests that damage their property—crops, for example—cause harms of kinds long understood in common law and recognized by public agencies. The concept of “ harm to the environment,” in contrast, has no standing in common law or legislation, no meaning for any empirical science, and no basis in a (...) political consensus other than might be drawn from the Endangered Species Act. As a generalization, the proposition that INS cause “environmental harm ”—since this concept is empty of legal, scientific, and political meaning—must rest on definition, diktat, or diatribe. As Evans et al. suggest, however, the idea of “ harm to the environment” is not always and certainly need not be arbitrary; it might gather significance in the context of a particular place through a political process that weighs economic concerns with cultural, religious, aesthetic, and other relevant beliefs, practices, and commitments that people who care about that place present. It is not clear, however, that adaptive management, which Evens et al. propose, will provide that democratic political process. (shrink)

Precision cell signaling activities of reactive electrophilic species (RES) are arguably among the most poorly‐understood means to transmit biological messages. Latest research implicates native RES to be a chemically‐distinct subset of endogenous redox signals that influence cell decision making through non‐enzyme‐assisted modifications of specific proteins. Yet, fundamental questions remain regarding the role of RES as bona fide second messengers. Here, we lay out three sets of criteria we feel need to be met for RES to be considered as (...) true cellular signals that directly mediate information transfer by modifying “first‐responding” sensor proteins. We critically assess the available evidence and define the extent to which each criterion has been fulfilled. Finally, we offer some ideas on the future trajectories of the electrophile signaling field taking inspiration from work that has been done to understand canonical signaling mediators. (shrink)

There are many ongoing debates within the scientific and ethical communities about the subject of animal welfare. This book distills some of the major themes of current debate into one volume, edited by internationally known names in the field of animal welfare. Each chapter is written by one or more leading experts who discuss, in an even-handed way, a provocative topic that will be of interest to anyone concerned with animal welfare. Issues covered include tail docking, farm animal production, neutering (...) of feral cats and the need to conserve habitats of native wild animals in the face of threats from non-native species. Chapters address the different values and priorities involved in dealing with these issues, including scientific and more explicit ethical approaches. Each chapter ends with questions for discussion that may help readers to engage with these dilemmas. (shrink)

The debate about a new geological epoch ‘The Anthropocene’ has helped spawn ‘Age of Man Environmentalism’ (AME). According to AME, humans’ planetary impact indicates that respect for independent nature can no longer serve as a guiding value for environmentalism. Traditional goals of nature preservation and restoration are grounded in the illusory ideal of pristine nature. Humans are now fully integrated into nature and must become responsible managers of an earth we have created, governing it by our ideals. This essay repudiates (...) AME, defending traditional environmental values of naturalness and respect for nature’s autonomy. AME’s exaggeration of human influence over Earth manifests an anthropocentric narcissism blind to nature’s ongoing agency. Rather than becoming gods or parents of a nature that allegedly needs us, human flourishing requires we strengthen our commitment to humility, restraint, and respect for nature’s gifted character. Naturalness becomes increasingly valuable the rarer it becomes, even in highly humanized areas. AME’s thoroughly managed future ignores the possibility of rewilding and turning nature loose. Its promotion of non-native species and ‘novel ecosystems’ attempts to polish the image of human-impacted nature and denigrates preserved wild areas. Taking seriously humans’ massive impact on earth does not require abandoning traditional environmental values. (shrink)

The article attempts to bridge semiotics with species conservation and management. Biosemiotic and cultural semiotic methodology is applied in the analysis of a case study – the early occurrence of the golden jackal in Estonia. Nine semi-structured interviews were carried out with the local inhabitants of the Matsalu region, professional zoologists and environmental officials who were involved in the golden jackals’ discourse. The interviews were analyzed for interactions between golden jackals and humans, expected ecological effects of golden jackals, communication (...) between different interest groups and central cultural motifs used to interpret the new species. It is argued that in the development of this discourse, the golden jackals’ own activity has played an essential role. At the same time, human cultural models also influence the interpretation of a new species to a considerable degree. Two of such models – the opposition of the own and the alien and the “settler’s” narrative – are brought out and analyzed. The effect of the fear of the unknown is also specified. To improve human communication about new or invasive species, it is suggested to raise awareness of the underlying cultural models and to use integrative communication as the developing discourse is dynamical and constantly changing for all interest groups. For a semiotic study of species management, it is suggested to combine methodology from biosemiotics, cultural semiotics and actor-network theory. (shrink)

We analyze the “Logical fallacies and reasonable debates in invasion biology: a response to Guiaşu and Tindale” article by Frank et al., and also discuss this work in the context of recent intense debates in invasion biology, and reactions by leading invasion biologists to critics of aspects of their field. While we acknowledge the attempt by Frank et al., at least in the second half of their paper, to take into account more diverse points of view about non-native (...) class='Hi'>species and their complex roles in ecosystems, we also find the accusations of misrepresenting invasion biology, for instance by “cherry-picking” and “constructing ‘straw people’”, directed at the Guiaşu and Tindale study to be unwarranted. Despite the sometimes harsh responses by leading invasion biologists to critics of their field, we believe that persistent and fundamental problems remain in invasion biology, and we discuss some of these problems in this article. Failing to recognize these problems, and simply dismissing or minimizing legitimate criticisms, will not advance the cause, or enhance the general appeal, of invasion biology and will prevent meaningful progress in understanding the multiple contributions non-native species can bring to various ecosystems worldwide. We recommend taking a more open-minded and pragmatic approach towards non-native species and the novel ecosystems they are an integral part of. (shrink)

The twelfth-century narrative Ḥayy ibn Yaqẓān by Ibn Ṭufayl recounts the life of Ḥayy, a feral man who teaches himself philosophy while living on a desert island. Ibn Ṭufayl gives two explanations of how Ḥayy came to the island. In one version, Ḥayy generates spontaneously on the island; in another, he washes up on the island as an infant. This paper attempts to resolve these contradictory narratives by appealing to a previously unexplored source text for Ḥayy ibn Yaqẓān, Sarāʾir al-nutaqāʾ (...) by Jaʿfar b. Manṣūr al-Yaman. Sarāʾir is an esoteric Ismāʿīlī text in which the author uses stories about Adam and other prophets to elaborate a Neoplatonist-inspired theology. Jaʿfar distinguishes between Adam as a symbol of the atemporal origination (ibdāʿ) of all natural forms, and the corporeal Adam of Ismāʿīlī history. Due to narrative and conceptual similarities between Jaʿfar’s and Ibn Ṭufayl’s treatment of their protagonists, I argue that the two versions of Ḥayy’s nativity allegorize the duality of Neoplatonic cosmology. Spontaneous generation dramatizes the atemporal creation of the human form, whereas the infant Ḥayy’s landing on the island reinforces the philosophical belief in the eternity of species. Both Jaʿfar and Ibn Ṭufayl appeal to the Neoplatonic doctrine of emanation to reconcile the eternity of the physical world with belief in God’s creative agency. The resemblance of Ḥayy ibn Yaqẓān to Sarāʾir prompts broader reconsidera­tion of Ismāʿīlī influence on non-Ismāʿīlī intellectual culture. (shrink)

Literature on place makes use of concepts like authenticity and is often structured around a critique of homogeneity or placelessness. This critique is reinforced by the discourse of conservation biology with its emphasis on protecting biodiversity and condemning some non-native species. However, a common emotional response of humans, when they are displaced, is to make where they are like where they felt at home. The debate around invasive species needs careful handling for both ecological and social reasons. (...) This paper addresses a gap in that debate by taking account of the emotional involvement of humans with plants and their caring for the immediate environment through the activity of gardening.

This article outlines the ecological and ethnobotanical characteristics of the monkey-puzzle tree (Araucariaaraucana), a long-lived conifer of great importance to the indigenous population living in and around its range in the southern Andes. The article also considers the pre-Columbian and historical use of indigenous fire technology. Conclusive evidence of indigenous burning is unavailable. However, our knowledge of native fire ecology elsewhere and our understanding of monkey-puzzle's ecological response to fire suggest that indigenous people probably burned in the past to (...) facilitate the growth of monkey-puzzle trees relative to other species. The obstacles to recovering and redeploying a defunct fire-based production strategy include the vulnerable condition of monkey-puzzle stands after decades of intense logging and burning (by non-indigenous settlers), inadequate access to land and resources by the region's indigenous inhabitants, livestock pressure, depletion of game animals that were once hunted with fire, and reluctance by indigenous people to embrace old production strategies that have been supplanted by new ones based on domesticated animals and crop cultivation. Prescribed burns in selected areas offer an effective way to assess the feasibility of indigenous burning as an alternative to more conventional development initiatives. (shrink)

In this dissertation I argue for a theory of rectificatory justice, and apply that theory to circumstances involving two social groups generally thought to have been historically wronged, viz., Native Americans and African Americans. ;Development of a conception of rectificatory justice is begun in Chapter 1 by examining the distinction between distributive justice and rectificatory justice, and by suggesting a theory of compensation. It is argued that the notion of compensation cannot provide an adequate ground for a species (...) of justice. ;I argue in Chapter 2 that a taxonomy of justice ought to consist of only two species, viz., distributive justice and rectificatory justice. In addition to compensation, the view of rectification argued for includes accounts of restoration, apology, and punishment. Some theories of so-called corrective justice are examined, and are found to be morally inadequate. ;In Chapter 3, I examine several views of a right to compensation, including those of Joel Feinberg and Judith Jarvis Thomson. Jules Coleman's claim that a requirement in justice for compensation can arise without the transgression of rights is examined and then rejected. ;After suggesting a theory of social groups, and adopting Allen Buchanan's account of groups rights, I argue in Chapter 4 that rectification rights can be legitimately ascribed to social groups. I assess the practical implications of my theory of rectificatory justice by applying it to two cases. In the first case, I argue that the fishing rights that were restored to Native American tribes of the Northwest as a result of U.S. v. Washington are justified when grounded on their right to rectification; hence, the claim that the restoration of these rights constituted an injustice to non-Native American fishing interests is mistaken. In the second case, I show how a right to rectification can legitimately be ascribed to African Americans as a group. ;The dissertation concludes with Chapter 5, where I consider several justificatory arguments for a moral statute of limitations on injustice. I conclude that a significant part of any such argument must ultimately rest on our judgements about competing claims. (shrink)

Стаття присвячена питанню, як native speaker реалізує свою владу над non-native speaker. Дослідження виконано в рамках теорії лінгвістичного імперіалізму. Для розкриття цих відносин вводиться концепт права на корегування. Для описання фігур native speaker та non-native speaker звертаємося до дослідників лінгвістичного імперіалізму, зокрема Р. Філліпсона, Ю. Цуди тощо. Вказується, що стандартним поглядом на панування native speaker є соціально-економічний, де native speaker постає як фігура, довкола якої концентруються можливості економічної взаємодії та економічний профіт. Натомість, право на (...) корегування демонструє владу native speaker на комунікативному рівні. Суть права на корегування наступна: native speaker як той, хто первісно занурений у мову і краще розуміє її, має право корегувати/виправляти мову non-native speaker. Для розкриття цього концепту звертаємося до концепту соціолектів Р. Барта та стратегій виключення, описаних Ж. Рансьєром. Основною для права на корегування виступає ідея, що мову найкраще може знати той, хто укорінений у мовне і культурне середовище, звідки походить мова – ця ідея є фігурою системності у розумінні Р. Барта. Право на корегування виконує декілька функцій. По-перше, це практика дискредитації мовлення non-native speaker, маркування його як шуму. По-друге, це практика інтерпеляції та формування non-native speaker як об’єкту мовлення, а native speaker – на Суб’єкта. По-третє, це можливість привласнення мовлення non-native speaker, а отже, позбавлення цього мовлення властивості імперативності, влади. Метою лінгвістичного імперіалізму є створення єдиної (глобальної) логіки виключення non-native speakers з (глобального) комунікативного простору. В цій логіці мова виступає як код, подібний до того коду, що описував Ж. Дельоз. (shrink)

Most restoration projects are designed to approximate the species composition and ecotypes ecologists and historians determine were present in an area at some point in the historical past. In most cases, although somewhat arbitrary, the specific time chosen is based on an understanding of historic species composition and anthropogenic disturbances.Although restoring an area to the estimated, historical vegetation types is widely accepted, the exclusory nature of the restoration process often actively eliminates not just invasive species, but also (...) non-invasive, nonnative species as well as displaced native species. These exclusory activities echo patterns of domination and degradation that led to a need for restoration in the first place. Although the domination present in restoration stems from an earnest desire to repair harms inflicted by human carelessness, it at the same time enforces a human conception of the ideal landscape. Attending to ecofeminist concepts such as inclusivism and pluralism, and embracing their rejection of dualistic thinking and the logic of domination demands an expanded tolerance within the practice of ecological restoration. An expanded ecofeminist conceptualization of restoration, a restorashyn, attempts to reduce the presence of overt human domination of the land. Doing so may ultimately mean that the species composition of an ecofeminist restorashyn will not be purely native, but may instead include a diverse mix of both native and non-invasive, nonnative species.

Prior to this intervention the site used to be a degraded fiscal property, that functioned as a bus yard, a police legal deposit, and a restaurant parking lot. Underneath it runs the Maldonado stream culvert, covered by a concrete slab at a depth of only -20cm. Next to the site is a 5m high railroad embankment. The plot is strategically located at the end of Juan B. Justo avenue and works as a gateway to the Tres de Febrero park (also (...) known as Bosques de Palermo, the Buenos Aires’s biggest green space designed by Charles Thays in 1875). It is situated in the neighborhood of Palermo, an area that underwent a vertiginous residential and commercial expansion since the late 90´s. -/- The design approach is influenced by the adjacent urban fragments: the grounds of the Sociedad Rural Argentina, the surrounding Avenues Santa Fe-Sarmiento; the opening of Darregueyra street expected for the near future, the implementation of historic preservation guidelines for the Tres de Febrero Park, and the proposal for the development of nearby railroad yards. -/- Specifically, the project seeks to minimize the impact of the fast traffic that runs along Bullrich avenue, improving pedestrian and cycle access to the park. At the same time it defines new landscape features, utilizing the earth made available by the tunneling works of a new subway line. -/- The project comprises the structuring of an existing 800 meter long embankment and the transformation of the sidewalk into a public promenade. This is achieved through a wider sidewalk of 12m on average, which is part of a series of longitudinal stripes ranging from high speed to quiet spaces. The first band of grass and aged tipas (tipuana tipu) buffer pedestrian and cyclist from automotive traffic. Cycle traffic is organized on its own lane. The sidewalk itself contains several bays that act as urban lounges. Next, a continuous concrete bench delimits the beginning of the slope, backed by a stripe of grass that works as a soft extension. Finally, plants for contemplation are arranged as undulating traces. Rhythmic use of retaining gabions defines longitudinal segments of varying slope, unifying the spacial criterion. This series is punctuated by an amphitheater and framed by triangular plazas at the corners. -/- Material choices for hard surfaces are constrained by concerns of durability, low cost, and consistency with other ongoing public works. -/- Hard materials, as well as the plant selection needed to be low-maintenance. The palette was kept to reinforced concrete, granitic slabs, and granite stone in large size –forming retaining gabions- and as loose finishing for pavements. Likewise, the lack of a protective enclosure and of continuous surveillance dictated that urban furniture and fixtures be anti-vandalic. The stealing of these components –from inspection lids, to benches, to plants- is a common problem in urban spaces in many Latin American cities. To prevent this, fixtures must be designed according to precise specifications regarding their weight, fixing and anchoring systems, and mechanical parts. -/- Sidewalks are organized through a 6 meter grid made of granitic white slab, infilled with textured combed nonslip concrete modules. Extended bays and corner squares are finished with white and black slabs respectively. These materials are similar to another used in public spaces under construction, in the believe that it creates a collective identification of themselves along the city. -/- The continuous reinforced concrete bench is 1.10 m wide, in order to allow people to use it in non-conventional ways. Further up on the slope, undulating paths separate plant species and provide access for gardening, but are also open to use by the public. They are paved with 2 meter-long precast concrete slabs (smaller and lighter pieces were avoided to deter robbery). As they reach the gabions they connect with sloping paths covered with loose granitic stones. The gabions themselves allow the creation of varying slopes while contributing to retaining the soil, which is reinforced with geosynthetic fabric in the perimeter to avoid landslides originated by strong rains typical of the region. -/- Urban furniture is featured on the wider bays of the sidewalk and at corner plazas. It includes seats, water fountains, bicycle racks, wastepaper baskets. As a counterpoint to the linear concrete bench, groups of concrete seats are arranged informally. These seats are a reinterpretation of the dynamic BKF chair (also known as Butterfly chair), the classic Argentinean design of the 1930’ by Antonio Bonet, Juan Kurchan, and Jorge Ferrari-Hardoy. A few low concrete tables complete these spaces as authentic urban lounges. Lighting design accompanies the general features of the project and creates a new scenography emphasizing night-time usage. -/- Landscape gardening criteria is set up by a selection of various species of high-resistant pasture (grass). The higher the slope, the higher the grass, increasing the final volumetric result. Based on considering the original tipas line (tipuana tipu, a species from the north of Argentina, yellow flowering) as a vertical wall that frames the view, the horizontal stripes contain a single species each, differing in size, shade and flowering periods –adding, in the middle band, a changing color on the big green plane slope in the same chromatic range. The final configuration of the stripe sequence from bottom to top: bermuda grass, bulbine frutescens, euryops pectinatus. The upper band existing native species is reinforced with new samples: paspalum exaltatum + cortadera selloana and ipomea + thumbergia climbing the railway fence. Each sector between gabions has an automated system of drip irrigation. Near the corner plazas, several palms are planted to provide shade and identity to the street-crossing. -/- The intervention proposes an ambivalent effect on the landscape, trascending the merely ornamental by accompanying the motorist in speed, while conforting the pedestrian with spaces for contemplation and urban relax.

In this note, my aim is to point out a phenomenon that has not received much attention; a phenomenon that, in my opinion, should not be overlooked in the professional practice of philosophy, especially within feminist efforts for social justice. I am referring to the way in which being a non-native speaker of English interacts with the practice of philosophy.1 There is evidence that non-native speakers are often perceived in prejudiced ways. Such prejudiced perception causes harm and, more (...) importantly, constitutes wrongdoing. As in other cases of prejudiced perception and biased behavior, it would be pretentious and misguided to expect philosophers and the philosophy profession to be free from this vice. There are good reasons to think that this prejudiced perception is bad not only for the persons who are perceived in such a way, but also for the profession, for it might make us miss important things that could improve philosophy in general. I claim we should be more sensitive to this phenomenon, both out of concern for justice, and for the sake of doing better philosophy. (shrink)

As the demand for English language skills among non-native speakers globally has grown steadily so too has the number of ‘global textbooks’ for ELT aimed at a world market. Concurrently, critical perspectives of the expansion of English have begun to challenge the view that native speaker contexts ‘own’ English. Based on the aforementioned, and on reflective approaches to culture, our objective is to analyze critically the representations of speakers of English as a second or foreign language offered by (...) two global ELT textbooks, to discuss the issues of essentialization and reproduction of stereotypes about the “non-native” speakers of English and their sociocultural characteristics in the constructed image. To achieve this purpose, we apply a methodology based on a sociocognitive approach to Critical Discourse Analysis (CDA) (Van Dijk, 2013), the concept of sociocultural knowledge as stated by the Common European Framework of Reference for Languages (CEFR), and critical perspectives of culture according to Holliday, Kullman, and Hyde (2004). Our findings indicate that, though the books include ‘non-native’ speakers in an attempt to address multiculturalism, their representation is generic, portraying a reified image of their sociocultural traits and presenting diversity mostly through national labels.

Sociolinguistic research shows that listeners' expectations of speakers influence their interpretation of the speech, yet this is often ignored in cognitive models of language comprehension. Here, we focus on the case of interactions between native and non-native speakers. Previous literature shows that listeners process the language of non-native speakers in less detail, because they expect them to have lower linguistic competence. We show that processing the language of non-native speakers increases lexical competition and access in general, (...) not only of the non-native speaker's speech, and that this leads to poorer memory of one's own speech during the interaction. We further find that the degree to which people adjust their processing to non-native speakers is related to the degree to which they adjust their speech to them. We discuss implications for cognitive models of language processing and sociolinguistic research on attitudes. (shrink)

A defining characteristic of primary emotions is that they occur in wide variety of species. Secondary emotions are thought to be restricted to humans and other primates. We report evidence from two studies investigating claims of primary and secondary emotions in non-primate species. Study 1. We surveyed 907 owners about emotions that they had observed in their animal. Participants reported primary emotions more frequently than secondary emotions and self-conscious emotions more frequently than self-conscious evaluative emotions. Jealousy was reported (...) at very high levels (81% of dogs and 79% of horses), which was surprising as jealousy is generally defined as a secondary emotion. Study 2. Forty dog owners were interviewed about the contexts and behaviours that led them to claim their animal was jealous. There was coherence and consistency in the behavioural descriptions of jealousy. We claim that such reports provide evidence for the existence of secondary emotions in non-primate species as predicted by theorists such as Buck (Citation1999). (shrink)

Although speech categories are defined by multiple acoustic dimensions, some are perceptually weighted more than others and there are residual effects of native-language weightings in non-native speech perception. Recent research on nonlinguistic sound category learning suggests that the distribution characteristics of experienced sounds influence perceptual cue weights: Increasing variability across a dimension leads listeners to rely upon it less in subsequent category learning (Holt & Lotto, 2006). The present experiment investigated the implications of this among native Japanese (...) learning English /r/-/l/ categories. Training was accomplished using a videogame paradigm that emphasizes associations among sound categories, visual information, and players’ responses to videogame characters rather than overt categorization or explicit feedback. Subjects who played the game for 2.5 h across 5 days exhibited improvements in /r/-/l/ perception on par with 2–4 weeks of explicit categorization training in previous research and exhibited a shift toward more native-like perceptual cue weights.

Oral communication often takes place in noisy environments, which challenge spoken-word recognition. Previous research has suggested that the presence of background noise extends the number of candidate words competing with the target word for recognition and that this extension affects the time course and accuracy of spoken-word recognition. In this study, we further investigated the temporal dynamics of competition processes in the presence of background noise, and how these vary in listeners with different language proficiency (i.e., native and non- (...) class='Hi'>native) using computational modeling. We developed ListenIN (Listen-In-Noise), a neural-network model based on an autoencoder architecture, which learns to map phonological forms onto meanings in two languages and simulates native and non-native spoken-word comprehension. We also examined the model's activation states during online spoken-word recognition. These analyses demonstrated that the presence of background noise increases the number of competitor words, which are engaged in phonological competition and that this happens in similar ways intra and interlinguistically and in native and non-native listening. Taken together, our results support accounts positing a “many-additional-competitors scenario” for the effects of noise on spoken-word recognition. (shrink)

Non-native listeners deal with adverse listening conditions in their daily life much harder than native listeners. However, previous work in our laboratories found that native Chinese listeners with native English exposure may improve the use of temporal fluctuations of noise for English vowel identification. The purpose of this study was to investigate whether Chinese listeners can generalize the use of temporal cues for the English sentence recognition in noise. Institute of Electrical and Electronics Engineers sentence recognition (...) in quiet condition, stationary noise, and temporally-modulated noise were measured for native American English listeners, native Chinese listeners in the United States, and native Chinese listeners in China. Results showed that in general, EN listeners outperformed the two groups of CN listeners in quiet and noise, while CNU listeners had better scores of sentence recognition than CNC listeners. Moreover, the native English exposure helped CNU listeners use high-level linguistic cues more effectively and take more advantage of temporal fluctuations of noise to process English sentence in severely degraded listening conditions [i.e., the signal-to-noise ratio of −12 dB] than CNC listeners. These results suggest a significant effect of language experience on the auditory processing of both speech and noise. (shrink)

Despite a continued focus exploring the factors related to plagiarism, the relationship between English language ability and plagiarism occurrences is not fully understood. Multiple studies involving student or faculty self-reporting of plagiarism have shown that students often claim English language ability is one of the main reasons why they commit plagiarism offences; however, little research has tested these claims in a rigorous, quantitative manner. This paper presents the findings of an analysis of data collected in a private, international university located (...) in Vietnam, from non-native English speaking students studying business degrees. Analysis of the data builds on previous studies by showing that there are statistically significant differences in the English language abilities of students who have previously committed plagiarism offences, compared to students who have not, suggesting that programmes designed to improve the academic English skills of non-native English speaking students may help reduce incidences of plagiarism.

Research investigating listeners’ neural sensitivity to speech sounds has largely focused on segmental features. We examined Australian English listeners’ perception and learning of a supra-segmental feature, pitch direction in a non-native tonal contrast, using a passive oddball paradigm and electroencephalography. The stimuli were two contours generated from naturally produced high-level and high-falling tones in Mandarin Chinese, differing only in pitch direction ( Liu and Kager, 2014 ). While both contours had similar pitch onsets, the pitch offset of the falling (...) contour was lower than that of the level one. The contrast was presented in two orientations (standard and deviant reversed) and tested in two blocks with the order of block presentation counterbalanced. Mismatch negativity (MMN) responses showed that listeners discriminated the non-native tonal contrast only in the second block, reflecting indications of learning through exposure during the first block. In addition, listeners showed a later MMN peak for their second block of test relative to listeners who did the same block first, suggesting linguistic (as opposed to acoustic) processing or a misapplication of perceptual strategies from the first to the second block. The results also showed a perceptual asymmetry for change in pitch direction: listeners who encountered a falling tone deviant in the first block had larger frontal MMN amplitudes than listeners who encountered a level tone deviant in the first block. The implications of our findings for second language speech and the developmental trajectory for tone perception are discussed. (shrink)

The article aims to shed light on teaching the Arabic language in non¬-Arab countries, especially since the Arabic language it is the main gateway to learning the Qur’an and its sciences, the current reading also aspires of the Arabic language and the reality if its teaching methods to non Arabic speakers, and the obstacles the prevent the educational process from being achieved. The article also shows the role of reading in teaching the Arabic language to non-native speakers, reading is (...) on one of transferring knowledge, and reading enriches perceptions and expands knowledge and information, The current reading aspires to know the different types of reading, as each has characteristics that differ from the others, Therefore, knowing the types of reading and methods of teaching them contributes to the status of teaching Arabic as a foreign language, and constitutes a means to understand and communicate it correctly and soundly.The work was divided into axes. In the first axis, the research will reveal the status of the Arabic language, whether for its speakers or for non-native speakers，It gained this status from being the language of the Qur’an, In addition to the fact that it contributes to the throne of languages by speaking them and using them to understand religious, economic, cultural and commercial matters.The second axis will focus on the meaning of teaching the Arabic language to non-native speakers, and teaching it by transmitting it to them by helping another individual to communicate with it and learn it as a second language.Then, the reality of Arabic language teaching curricula and the problems they face were discussed. Especially with the presence of a large number of these curricula, with their different plan, method, and time duration, the teacher here finds himself faced with confusion in choosing the appropriate curriculum for the group - non-Arabic speakers - he is entrusted with teaching, and which suits their abilities and intellectual inclinations.The article also shows that there are good curricula that have been highly successful in delivering and transferring the academic content to the learner. This is due to its respect for a set of pedagogical rules and controls and the hierarchy of the curriculum. The clearer the curriculum is and built on specific foundations and elements, the more effective and profitable it is.There is no doubt that it is not possible to download and teach any educational curriculum without a teacher who has several scientific methods and skills. That is, he must have a set of skills and be armed with a variety of methods in teaching the Arabic language to non-native speakers. Something that contributes to the success of the educational process.A good professor is one who diversifies his methods while teaching non-Arabic speaking students. Therefore, the article aims to pay attention to the teacher and train him according to certain basics, including the cultural basis of the country in which he will study, and the cognitive and professional basis. The research also recommended the need to hold training courses and workshops to train teachers of the Arabic language to non-native speakers.The research has confirmed that reading has an important and fundamental role in teaching the Arabic language to non-native speakers, and that this skill contributes to providing the learner with a large linguistic resource, as well as benefiting from the depths of Arabic books, and also helps in improving the level of pronunciation and communication with a good master of the Arabic language.The article also explains that teaching the Arabic language to non-native speakers suffers from several obstacles and obstacles that prevent achieving the goal of the educational learning process, including reading weakness among learners, especially at the level of pronunciation, in addition to inversion, substitution, and lack of distinction between similar sounds in pronunciation.The current reading shows that despite these problems and obstacles; However, the experiences related to teaching the Arabic language to non-native speakers are moving in the right direction.The article relied on the descriptive and analytical approach. To describe and analyze the phenomenon of teaching the Arabic language to non-native speakers, with the need to point out that the proposed reading is not final and does not claim to have the final say or possess the “truth”, as long as it is one among other possible readings.

The article reveals the problems of listening comprehension in a foreign-language audience, in particular, by students who are non-native speakers. The theoretical part is a brief characteristic of listening as a type of speech activity: the content of the term, its internal components – the psychophysiological mechanisms involved, the difficulties associated with them. In the practical part the authors of the article demonstrate exercises from the purposefully developed lesson on the removal of difficulties in the perception of sounding speech (...) in non-native speakers children of middle school age, consisting in the systematic development of mechanisms of listening comprehension. Based on the analysis of the experimental lesson, solutions for systematic and consistent work in the classes within the additional remedial course in the Russian language in order to prevent errors and difficulties, as well as to facilitate the process of listening comprehension are proposed.

Most early studies of consciousness have focused on human subjects. This is understandable, given that humans are capable of reporting accurately the events they experience through language or by way of other kinds of voluntary response. As researchers turn their attention to other animals, “accurate report” methodologies become increasingly difficult to apply. Alternative strategies for amassing evidence for consciousness in non-human species include searching for evolutionary homologies in anatomical substrates and measurement of physiological correlates of conscious states. In addition, (...) creative means must be developed for eliciting behaviors consistent with consciousness. In this paper, we explore whether necessary conditions for consciousness can be established for species as disparate as birds and cephalopods. We conclude that a strong case can be made for avian species and that the case for cephalopods remains open. Nonetheless, a consistent effort should yield new means for interpreting animal behavior.

Epstein et al.'s “full access to Universal Grammar” position is conceptually and empirically problematic. Its shortcomings are illustrated through a brief discussion of the following issues: (1) initial versus final states of grammatical knowledge in a second language, (2) knowledge of gradience of grainmaticality, (3) optionality and retention in non-native grammars, and (4) the empirical measurement of syntactic knowledge.

The purpose of this study was to investigate how the subjective impression of English speech would change when pause duration at punctuation marks was varied. Two listening experiments were performed in which written English speech segments were rated on a variety of evaluation items by both native-English speakers and non-native speakers (native-Chinese speakers and native-Japanese speakers). The ratings were then subjected to factor analysis. In the first experiment, the pauses in three segments were made into the (...) same durations, from 0.075 to 4.8 s. Participants rated the segments on 23 evaluation items on a rating scale from 1 to 10. A varimax rotation after PCA (principal component analysis) led to two factors that were related to speech style. These two factors could be interpreted as representing speech naturalness and speech rate. Speech segments with a pause duration of 0.6 s received the highest naturalness evaluation, while perceived speech rate decreased as the physical pause duration increased, without any changes in utterance segments. In the second experiment, a full-factorial design of pause durations (0.15, 0.3, 0.6, 1.2, and 2.4 s) within and between sentences, i.e., for commas and for periods, was implemented in two speech segments. The original speech segments and speech segments without any pauses were also included as control conditions. From ratings on 12 evaluation items, similar to Experiment 1, two factors representing speech naturalness and speech rate were obtained. The results showed again that the perceived speech rate decreased with an increase only in pause duration. As for speech naturalness, the highest evaluations occurred when pause durations were 0.6 s within sentences, and either 0.6 or 1.2 s between sentences. This recommends fixing all pause durations to 0.6 s as a practical way to train non-native speakers to make their spoken English appear more natural. (shrink)

Recent investigations with non‐model species and whole‐genome approaches have challenged several paradigms in animal epigenetics. They revealed that epigenetic variation in populations is not the mere consequence of genetic variation, but is a semi‐independent or independent source of phenotypic variation, depending on mode of reproduction. DNA methylation is not positively correlated with genome size and phylogenetic position as earlier believed, but has evolved differently between and within higher taxa. Epigenetic marks are usually not completely erased in the zygote and (...) germ cells as generalized from mouse, but often persist and can be transgenerationally inherited, making them evolutionarily relevant. Gene body methylation and promoter methylation are similar in vertebrates and invertebrates with well methylated genomes but transposon silencing through methylation is variable. The new data also suggest that animals use epigenetic mechanisms to cope with rapid environmental changes and to adapt to new environments. The main benefiters are asexual populations, invaders, sessile taxa and long‐lived species. (shrink)

Although the efficacy of teacher written feedback has been widely investigated, relatively few studies have been conducted from feedback practitioners' perspectives to investigate teachers' beliefs regarding it, particularly compare beliefs held by teachers with different sociocultural and linguistic backgrounds. Consequently, much remains to be known about teachers' conceptions about written feedback, who has different first languages. To bridge such a gap, we conducted this qualitative study to examine the similarities and differences between native English-speaking and non-native English-speaking teachers' (...) beliefs in Chinese University EFL settings. We analyzed the in-depth interviews with eight teachers through thematic analysis. The findings showed that NES and NNES teachers espoused a range of beliefs in relation to the five themes of written feedback: Purpose, scope, focus, strategy, and orientation. While they shared similar beliefs with regard to feedback focus, their beliefs differed in terms of feedback scope. Important implications are discussed for educational practices. (shrink)
