A participatory rural appraisal inthree West African countries examined thepossibility for replacing chemical pesticidesto control locusts and grasshoppers with abiological control method based on anindigenous fungal pathogen. The fungus iscurrently being tested at different sites inthe Sahel and in the humid tropics of WestAfrica. Structured group interviews, individualdiscussions, and field visits, were used toobtain farmers' perceptions of locust andgrasshoppers as crop pests, their quantitativeestimation of crop losses, and theirwillingness to pay for locust control. Farmersas well as plant protection officers generallyperceived (...) locusts and grasshoppers as importantpests that cause significant damage. Farmerswere aware of some of the risks of the use ofchemical pesticides, but not of the potentialalternatives. The use of the fungus in anoil-formulation and standard Ultra Low Volume(ULV) equipment was demonstrated, and theresults discussed with farmers. Theirimpressions of biological control werefavorable, and they expressed an interest inusing the technology. Farmers' expressedwillingness to pay for locust control is small,but not negligible. Locusts and grasshoppersare very visible pests and thus amenable topressure from farmers to local administrators,as well as by farmers' relatives in the city onthe national government. Therefore, politicalpressure for locust control is strong, althoughnational governments spend little on it,depending mostly on foreign donors. Donors areincreasingly worried about the environmentaleffect of the large amounts of chemicalpesticides used on locust control, and arepushing for more benign alternatives. Theresults of the present survey indicate thatthere may be a potential market for abiopesticide against grasshoppers and locustson cash crops in the humid areas. The potentialmarket in the Sahel depends on a reduction ofcosts or a subsidy of its price. This subsidycould be justified by the expected reduction inenvironmental and health costs when replacingchemical pesticides. Since donors are thecurrent purchasers of chemical pesticides forthe Sahel, they would also be expected to beinvolved in the purchase of the biologicalproduct. (shrink)

We present a novel spontaneous collapse model where size is no longer the property of a physical system which determines its rate of collapse. Instead, we argue that the rate of spontaneous localization should depend on a system’s quantum Integrated Information, a novel physical property which describes a system’s capacity to act like a quantum observer. We introduce quantum Integrated Information, present our QII collapse model and briefly explain how it may be experimentally tested against quantum theory.

The rationalization of context-based choice is usually based on the assumption that preferences are context-dependent. In this paper, we show that context-based choice can be due to the characteristics of the choice procedure applied by the individual and not to the dependence of preferences (stochastic or deterministic) on the context. Our arguments are illustrated focusing on the much-studied dominated-alternative effects.

In this article I offer a way of interpreting Richard Rorty's political suggestions. I believe Rorty's lack of offering concrete proposals for dealing with the usual key problems of liberalism is deliberate. I look at this lack from a generous point of view and claim that what Rorty offers us is another kind of political intentionality. As a pragmatist, Rorty does not look for a foundational way of justifying things but, instead, searches for a description that makes liberalism an attractive (...) practice. Following Gadamer and Rorty, I intend looking at liberalism as a kind of game and a public lifestyle. I claim that such a prior understanding illuminates and articulates liberal key terms such as: freedoms, public sphere, respecting the other. (shrink)

Scholars of the Mamluk Sultanate generally maintain that the status of all the mamluks was that of an elite, and that the mamluks were proud of their slave origin even after manumission. It is here argued that these assertions are based on a misconception of the term mamluk as used in Mamluk sources. The term mamluk has a double meaning: slave and servant, and it frequently expresses subordination, obedience and servitude. It is never used to express pride in slave status (...) or slave origin. There is no evidence that manumitted mamluks were proud of their slave status. On the contrary, manumitted slaves with aspirations made great efforts to repress their servile past by claiming an exalted origin or by creating marital ties with established families. Mamluks were considered property and they lacked a legal identity of their own. They were often manumitted only upon their master�s death. They perceived themselves as slaves for lacking family ties. Only an outstanding few succeeded in completely freeing themselves of their slave status and become members of a ruling elite with family ties. It seems that starting from al-Nasir Muhammad b. Qalawun�s third reign the enslavement of Turkish mamluks who had been sold by their families became more of a formality. On the other hand, non-Turkish mamluks, who were generally Christian war captives, were subject to discrimination. They were disdained, manumitted at a later age and prevented from establi- shing marital ties with the Qalawunids and creating their own families at a young age. They were perceived by their contemporaries as being �more slaves� than the Turkish mamluks. (shrink)

SARS-CoV-2 has unleashed an unprecedented global crisis that has caused the demand for essential goods, such as medical and sanitation products, to soar while simultaneously disrupting the very supply chains that allow individuals and institutions to obtain those essential goods. This has resulted in stark price increases and accusations of price gouging. We survey the existing philosophical literature that examines price gouging and identify the key arguments for regulators permitting such behavior and for regulators restricting such behavior. We demonstrate how (...) the existing accounts are designed for localized emergencies rather than global persistent crises such as the coronavirus pandemic. In light of this, we highlight an understudied justification for price gouging that is much more salient during global crises: incentivizing increased production of essential goods. Furthermore, we pinpoint three conditions that help determine whether authorities should restrict price gouging during the coronavirus pandemic and similar global crises. (shrink)

This study examines the linguistic construal and cognitive representation of time and viewpoint in the genre of news narratives. We present a model of mental spaces that involves a News Space in which the deictic center is construed of the news actors at the time the newsworthy events took place, and a Reality Space in which the deictic here-and-now center of journalist and reader is construed. This model explains how the dynamic representation of narrative news discourse, characterized by shifts in (...) time and viewpoint, is steered by linguistic devices. An analysis of Dutch news narratives shows that temporal adverbs such as yesterdayand shifts from present tense to past tense may signal a moveforwardin narrative time, to a viewpoint in the future relative to the narrative now-point, rather thanbackward. These atypical time shifts can be accounted for by presupposing an Intermediate Space located at a point in time between the News Space and the Reality Space where the progression of narrative time comes to a halt and experiences are rather relived than reported. The salience of the Intermediate Space may be signaled by quotative conditionals reflecting the viewpoints of implicitly quoted sources. These results clarify how tense and temporal deixis steer the linguistic construal of time and viewpoint in news narratives, demonstrating that time and viewpoint are closely linked in the cognitive representation of these narratives.

The display of artefacts always implies an external mediation that influences, and often codifies, the reception of the exhibits. Objects are manipulated, restored, appropriated, staged, in short displayed, through various representational strategies that include pedestals, labels, and showcases. These elements, that we could define as parerga, are often ignored because of their utilitarian function. Yet, they play an important role in the history of the artefacts and define the setting in which the objects can exert their agency. They not only (...) shape their meaning, but also determine the effect that these artefacts have on their viewers. Framing devices create the conditions for interactions between the individual and the object to take place. This publication aims to explore the relation between artefacts and viewers as they are manifested in framing devices, and to develop a new theoretical framework for thinking about the power of objects on display.

This study examines how audiovisual brand stories both invite and enable consumers to enact heroic archetypes. Integrating research on the archetypal structure of narratives with research on the event structure of narratives, we distinguish singular plot stories (i.e. stories that show a Hero’s Journey) from embedded plot stories (i.e. stories that not only show but also tell one or more Hero’s Journeys) and develop a conceptual and narratological framework to analyze their structural elements. Application of the framework to 20 brand (...) stories representing 8 different brands reveals meaningful variation in elements between the singular plot stories and embedded plot stories. Differences in the expression of archetypes and event structure are argued to evoke different types of Hero enactment which in turn result in different outcomes. We specifically hypothesize that the enactment of heroic archetypes in singular plot stories primarily results in catharsis (pleasure), whereas the enactment of heroic archetypes in embedded plot stories primarily results in an outcome we describe as phronesis: a form of moral sense making of the self that advances one’s practical wisdom and prudence. The final section of the paper discusses how cathartic and phronetic outcomes of hero enactment may foster the psychological bonding between brand and consumer, and invite consumers to align their moral values with the values that are reflected by heroic character traits. The central aims of the analysis presented are to provide an exploration of narrative phenomena in a reasonably broad range of brand story videos and foremost to provide a conceptual framework with an applicable instrument suited to analyze relevant categories in these brand stories. The present study is interdisciplinary in its approach to a contemporary, developing marketing phenomenon, applying psychological modeling of archetypes and heroic values with narratological insights on perspective-taking and story structure. Its contribution is to systemize, from a narratological viewpoint, how various narrative archetypes in brand video stories may contribute to the development of brand-consumer relations. (shrink)

In this introduction to the special issue on time and viewpoint in narrative discourse, we highlight the central contributions of the issue concerning the relation between the linguistic construal and cognitive representation of time and viewpoint. We explain how linguistic and gestural cues guide the representation of narrative time progression and argue that this representation involves various cognitive operations regulating the alignment between the viewpoints of narrator, addressee, and narrative characters. These operations are steered by a variety of linguistic phenomena, (...) including verb tense, adverbs, demonstratives, reduplication and negation, as well as body partitioning. We discuss how genre characteristics influence the relation between the linguistic and cognitive representation of time and viewpoint. Finally, we explain how the analyses presented in the various papers both demonstrate and clarify how the cognitive representation of time in narrative discourse relies on the human capacity to simultaneously manage multiple viewpoints, leading to the conclusion that time and viewpoint are closely related in the representation of narrative discourse.

Journal Name: Cognitive Linguistics Issue: Ahead of print.

In this paper, we seek to explain the power of perspective taking in narrative discourse by turning to research on the oral foundations of storytelling in human communication and language. We argue that narratives function through a central process of alignment between the viewpoints of narrator, hearer/reader, and character and develop an analytical framework that is capable of generating general claims about the processes and outcomes of narrative discourse while flexibly accounting for the great linguistic variability both across and within (...) stories. The central propositions of this viewpoint alignment framework are that the distance between the viewpoints of participants in the narrative construal – narrator, character, reader – is dynamic and regulated by linguistic choices as well as contextual factors. Fundamentally, viewpoint alignment is grounded in oral narrative interaction and, from this conversation, transferred to the written narrative situation, varying between demonstration and invasion of the narrative subjects and guiding readers’ route of processing the narrative (experientialversusreflective). Our claim is that variations in viewpoint alignment are functional to the communicative context and intended outcomes of narratives. This is illustrated with the analysis of a corporate journalistic narrative that comprises both interactional and non-interactional aspects of storytelling. The concept of viewpoint alignment further explains the oral fundaments of narrative discourse in conversational storytelling and poses new questions on the relation between the dynamic processing of stories on the one hand and their static outcomes on the other.

In this paper, the Helmholtz equation with quadratic damping themes is used for modeling the dynamics of a simple prey-predator system also called a simple Lotka–Volterra system. From the Helmholtz equation with quadratic damping themes obtained after modeling, the equilibrium points have been found, and their stability has been analyzed. Subsequently, the harmonic oscillations have been studied by the harmonic balance method, and the phenomena of resonance and hysteresis are observed. The primary and secondary resonances have been researched by the (...) multiple-scale method, and the conditions of stability of the amplitudes of oscillations are determined. Chaos is detected analytically by the Melnikov method and numerically using the basin of attraction, the bifurcation diagram, the Lyapunov exponent, the phase portrait, and the Poincaré section. The effects of all the parameters of the system are analyzed in detail, and special emphasis is placed on the new parameters. Through this analysis, the complex phenomena such as hysteresis, bistability, amplitude jump, resonances, and chaos have been obtained. The control of the parameters and the necessary conditions to control the aforementioned phenomena have been found. (shrink)

This volume addresses the intriguing issue of indirect reports from an interdisciplinary perspective. The contributors include philosophers, theoretical linguists, socio-pragmaticians, and cognitive scientists. The book is divided into four sections following the provenance of the authors. Combining the voices from leading and emerging authors in the field, it offers a detailed picture of indirect reports in the world’s languages and their significance for theoretical linguistics. Building on the previous book on indirect reports in this series, this volume adds an empirical (...) and cross-linguistic approach that covers an impressive range of languages, such as Cantonese, Japanese, Hebrew, Persian, Dutch, Spanish, Catalan, Armenian, Italian, English, Hungarian, German, Rumanian, and Basque.

Disruptions in theory of mind faculties and the ability to relate to an intersubjective reality are widely thought to be crucial to schizophrenic symptomology. This paper applies a cognitive linguistic framework to analyze spontaneous perspective-taking in two corpora of stories told by people with a schizophrenia diagnosis. We elicited natural narrative language use through life story interviews and a guided storytelling task and analyzed the linguistic construal of viewpoint in these stories. For this analysis, we developed a reliable and widely (...) applicable viewpoint model that allows for the categorization and quantification of speakers’ linguistic presentation and navigation of spatiotemporal domains. We found that our participants skillfully presented, navigated and embedded different narrative viewpoints through a variety of linguistic viewpoint devices. They presented complex viewpoints of other people in both the here-and-now of the interaction and the there-and-then of a narrative, and made use of transition markers to demarcate spatiotemporal discourse domains. We found no differences in viewpoint variables when comparing their guided stories to a control group. If problems with intersubjectivity are indeed an essential part of schizophrenia, an explanation of how this group can take on and navigate complex linguistic viewpoints in natural narrative interaction is called for.

O nosso artigo visa o estudo hagiográfico de Santa Quitéria, uma jovem mártir do século II, cuja vida se encontra envolvida em aspectos lendários, ainda pouco estudados. Filha de um nobre pagão, terá nascido na região de Braga, juntamente com mais oito irmãs gémeas. Os primeiros milagres datam do século VIII, altura em que começou a ser venerada como mártir, destino que partilhou com suas irmãs. O martírio é referido, pela primeira vez, no século XII, estando relatado nos Flos Sanctorum (...) de Alonso de Villegas e de Diogo do Rosário e inscrito no Martirológio Romano (22 de Maio). O culto de Santa Quitéria, promovido, particularmente, pelos jesuítas, encontra-se bem alicerçado na devoção popular que a invoca como advogada contra a raiva. A arquidiocese de Braga celebra a sua memória no dia 8 de Junho. Felgueiras não só lhe erigiu um santuário no local onde, supostamente, foi sepultada, como tem Santa Quitéria como padroeira.A iconografia desta nobre donzela romana faz alusão a certos episódios da sua vida e revela o instrumento material do martírio, aspectos que nos propomos analisar bem como fazer referência ao culto e às dificuldades causadas pelas diversas lendas sobre a sua vida.

Existem perto de 140 monumentos portugueses que ainda conservam pintura mural realizada entre os finais do século XV e os meados do século XVI. Por vicissitudes históricas diversas, a distribuição destes monumentos pelo território nacional é muito desigual, verificando-se uma concentração em templos rurais situados sobretudo no território de Entre-Douro-e- -Minho (c. 30%), em Trás-os-Montes (c. 25%) e na Beira Interior (c. 20%).A análise da iconografia destas pinturas permite tirar várias conclusões a respeito das principais devoções da época. Verifica-se (...) que São Sebastião era o santo mais representado, seguido por Santo António (de Pádua), Santa Catarina, São Pedro, São Miguel, São João Baptista e São Tiago, ao mesmo tempo que apenas a Anunciação e o Calvário têm uma representatividade equiparável à dos santos mencionados. Também é possível concluir que a preferência pelos santos referidos não estava dependente da invocação dos templos. Conclui-se, igualmente, que existe uma nítida diferenciação entre as imagens sacras representadas na zona dos templos cujo cuidado pertencia aos fregueses, a nave, e a zona sob a responsabilidade dos padroeiros, a cabeceira. Nesta comunicação pretende-se explicar quais os motivos que justificam a preeminência da representação de determinadas figuras do hagiológio cristão durante o período em causa, bem como a ausência de outras cuja presença seria expectável. Pretende-se explicar também as razões que ditam a diferenciação entre a iconografia das cabeceiras e a iconografia das paredes da nave. A análise conjugada destes dados permite trazer alguma luz sobre os motivos que justificam as principais devoções dos portugueses da época, sobretudo os que viviam em ambientes rurais. (shrink)

Porto has its own charm. It has a beautiful Douro river, the steep alleys of Gaia, Ribeira, Miragaia and shiny beautiful waterfronts. While you are strolling in the fishing village of Afurada, you can smell the sea. Watching the sunset with a mild breeze coming from the Atlantic Ocean can refresh the soul. It is difficult to be a non-local curious urban and nature lover like me and to stay at home in a magical city like Porto.

The volume gathers eleven studies on the intellectual exchanges during the Middle Ages among the three cultures which existed side by side in the same geographical area, i.e. the vast space from the British Isles to the Sahara Desert, and from the Douro Valley to the Hindu Kush. These three cultures – who may not be reduced to their confession or ethnicity – are historically related to each other in many respects, both material (trade, wars, marriages) and immaterial (the (...) interdependence among their religious narratives and their philosophical speculations). The studies herein presented focus on some peculiar examples of the transcultural interactions among exponents of the Arabic, Hebrew and Latin philosophical and theological traditions. While we do not want to downplay the fundamental role of the religious contexts, our focus on the linguistic denominations of these cultures aims at drawing attention to the conceptual medium, or rather media, which underlined and shaped the interactions and interplays among these traditions – interplays that were characterized by the contact of these three languages being used by people of different religious beliefs in their quest for knowledge: Spanish Jews writing in Arabic, Jews collaborating in the translation of Arabic texts into Latin through the vernacular, Western Muslims whose writings were read mainly by Jews and Christians in Hebrew and Latin.

O pintor tem espaço nos retábulos maneiristas, diminuindo o seu desempenho a favor do entalhador, à medida que o programa do Barroco Nacional se impõe na arte da talha. Em Portugal, nos séculos XVII e XVIII, definem-se os ofícios com fronteiras frágeis. Entalhador pode significar escultor, imaginário ou ensamblador – assim como o dourador é mencionado, muitas vezes, como pintor e estofador, numa polivalência artística notável. Cabe ao imaginário, na gramática barroca, apropriar-se dos espaços intercolúnios, entre outros, para cumprir as (...) encomendas dos santos em concordância com as determinações do Concílio de Trento.Os inventários, as Memórias Ressuscitadas de Entre-Douro-e-Minho (Francisco Craesbeeck, 1726), as Memórias Paroquiais de 1758 (A.N.T.T.) e um levantamento fotográfico privilegiam o percurso escultórico dos oragos e das invocações retabulares de templos no Baixo Tâmega e no Vale do Sousa. Neste sentido, pretende-se desenhar uma matriz dos espécimes mais recorrentes, estabelecendo assim a mancha das devoções nacionais nos concelhos de Amarante, Marco de Canaveses, Felgueiras e Penafiel.
