To ensure their survival in natural habitats, plants must recognize and respond to a wide variety of insect herbivores. Aphids and other Hemiptera pose a particular challenge, because they cause relatively little direct tissue damage when inserting their slender stylets intercellularly to feed from the phloem sieve elements. Plant responses to this unusual feeding strategy almost certainly include recognition of aphid salivary components and the induction of phloem‐specific defenses. Due to the excellent genetic and genomic resources that are available for (...) Arabidopsis thaliana (Arabidopsis), this plant was chosen as a model system to study the metabolic and transcriptional responses to infestation by two aphids, Myzus persicae (green peach aphid, a broad generalist) and Brevicoryne brassicae (cabbage aphid, a crucifer‐feeding specialist). Future research on Arabidopsis–aphid interactions will lead to the identification of aphid‐specific elicitors, components of the defense‐signaling pathway, and additional metabolic responses that are induced by aphid infestation.

Background In the ethical and clinical literature, cases of parents who want treatment for their child to be withdrawn against the views of the medical team have not received much attention. Yet resolution of such conflicts demands much effort of both the medical team and parents. Objective To discuss who can best protect a child9s interests, which often becomes a central issue, putting considerable pressure on mutual trust and partnership. Methods We describe the case of a 3-year-old boy with acquired (...) brain damage due to autoimmune-mediated encephalitis whose parents wanted to stop treatment. By comparing this case with relevant literature, we systematically explored the pros and cons of sharing end-of-life decisions with parents in cases where treatment is considered futile by parents and not (yet) by physicians. Conclusions Sharing end-of-life decisions with parents is a more important duty for physicians than protecting parents from guilt or doubt. Moreover, a request from parents on behalf of their child to discontinue treatment is, and should be, hard to over-rule in cases with significant prognostic uncertainty and/or in cases with divergent opinions within the medical team.

The knower paradox states that the statement ‘We know that this statement is false’ leads to inconsistency. This article presents a fresh look at this paradox and some well-known solutions from the literature. Paul Égré discusses three possible solutions that modal provability logic provides for the paradox by surveying and comparing three different provability interpretations of modality, originally described by Skyrms, Anderson, and Solovay. In this article, some background is explained to clarify Égré’s solutions, all three of which hinge on (...) intricacies of provability logic and its arithmetical interpretations. To check whether Égré’s solutions are satisfactory, we use the criteria for solutions to paradoxes defined by Susan Haack and we propose some refinements of them. This article aims to describe to what extent the knower paradox can be solved using provability logic and to what extent the solutions proposed in the literature satisfy Haack’s criteria. Finally, the article offers some reflections on the relation between knowledge, proof, and provability, as inspired by the knower paradox and its solutions. (shrink)

Signed utterances are densely packed with pointing signs, reaching a frequency of one in six signs in spontaneous conversations (de Vos, 2012; Johnston, 2013a; Morford & MacFarlane, 2003). These pointing signs attain a wide range of functions and are formally highly diversified. Based on corpus analysis of spontaneous pointing signs in Kata Kolok, a rural signing variety of Bali, this paper argues that the full meaning potentials of pointing signs come about through the integration of a varied set of linguistic (...) and extralinguistic cues. Taking this hybrid nature of pointing phenomena into account, it is argued that pointing signs may become an intrinsic aspect of sign language grammars through two mechanisms: morphemization and syntactic integration. Although not entailed in this research, this approach could implicate that some highly systematized pointing systems of speaking communities may to a degree be grammatical as well. (shrink)

In spoken interactions, interlocutors carefully plan and time their utterances, minimising gaps and overlaps between consecutive turns. Cross-linguistic comparison has indicated that spoken languages vary only minimally in terms of turn-timing, and language acquisition research has shown pre-linguistic vocal turn-taking in the first half year of life. These observations suggest that the turn-taking system may provide a fundamental basis for our linguistic capacities. The question remains however to what extent our capacity for rapid turn-taking is determined by modality constraints. The (...) avoidance of overlapping turns could be motivated by the difficulty of hearing and speaking at the same time. If so, turn-taking in sign might show greater toleration for overlap. Alternatively, signed conversations may show a similar distribution of turn-timing as spoken languages, thus avoiding both gaps and overlaps. To address this question we look at turn-timing in question-answer sequences in spontaneous conversations of Sign Language of the Netherlands. The findings indicate that although there is considerable overlap in two or more signers' articulators in conversation, when proper allowance is made for onset preparation, post-utterance retraction and the intentional holding of signs for response, turn-taking latencies in sign look remarkably like those reported for spoken language. This is consistent with the possibility that, at least with regard to responses to questions, speakers and signers follow similar time courses in planning and producing their utterances in on-going conversation. This suggests that turn-taking systems may well be a shared cognitive infrastructure underlying all modern human languages, both spoken and signed. (shrink)

A rapidly emerging hegemonic neuro-culture and a booming neural subjectivity signal the entry point for an inquiry into the status of the signifier neuro as a universal passe-partout. The wager of this paper is that the various appropriations of the neurosciences in the media and in academia itself point to something essential, if not structural, in connection with both the discipline of the neurosciences and the current socio-cultural and ideological climate. Starting from the case of neuroeducation, the genealogy of the (...) neurological turn is linked to the history of psychology and its inextricable bond with processes of psychologisation. If the neurological turn risks not merely neglecting the dimension of critique, but also obviating its possibility, then revivifying a psy-critique might be necessary in order to understand today’s neural subjectivity and its place within current biopolitics.

This intriguing and ground-breaking book is the first in-depth study of the development of philosophy of science in the United States during the Cold War. It documents the political vitality of logical empiricism and Otto Neurath's Unity of Science Movement when these projects emigrated to the US in the 1930s and follows their de-politicization by a convergence of intellectual, cultural and political forces in the 1950s. Students of logical empiricism and the Vienna Circle treat these as strictly intellectual non-political projects. (...) In fact, the refugee philosophers of science were highly active politically and debated questions about values inside and outside science, as a result of which their philosophy of science was scrutinized politically both from within and without the profession, by such institutions as J. Edgar Hoover's FBI. It will prove absorbing reading to philosophers and historians of science, intellectual historians, and scholars of Cold War studies. (shrink)

Introduction. Eating Disorders (EDs) are serious psychiatric disorders, impacting physical and psychosocial functioning, often with a chronic course and high mortality rates. The two continua model of mental health states that mental health is a complete state, that is not merely the absence of mental illness, but also the presence of mental health. This model was studied among ED patients by comparing the levels of well-being to the Dutch general population and by examining the of well-being and psychopathology. Method. A (...) total of 468 female ED patients participated in this study during application and intake at a specialized ED treatment centre in the Netherlands. They filled out questionnaires about well-being (MHC-SF), general psychopathology (OQ-45), and ED psychopathology (EDE-Q). Categorical and mean well-being levels were calculated. Also, the correlates of these variables were examined with Pearson correlation and multiple hierarchical regression analysis. Results. ED patients showed lower levels of emotional, psychological and social well-being on average compared to the general population. About 26% of the ED patients experienced low levels of well-being (languishing). However, also 13% experienced high levels of well-being (flourishing), varying between 9% in Anorexia Nervosa to 25% in Binge Eating Disorder. ED psychopathology and general well-being showed a moderate negative correlation. For patients with Bulimia Nervosa and Binge Eating Disorder however no such correlation was found. Lower general psychopathology, not having a history of hospitalization for the ED, and adaptive personal functioning were correlated with well-being among ED patients. Conclusion This study shows initial support for the two continua model of mental health among ED patients. Psychopathology and well-being should be considered as related, but distinct dimensions of mental health in ED patients. Further research should focus on the possible reciprocal relationships between psychopathology and well-being during recovery. It is recommended to monitor well-being during treatment and to implement interventions for well-being to realize complete recovery for those patients with inadequate levels of well-being. (shrink)

Recent years have seen a rapid growth in neuroscientific research, and an expansion beyond basic research to incorporate elements of the arts, humanities and social sciences. It has been suggested that the neurosciences will bring about major transformations in the understanding of ourselves, our culture and our society. In academia one finds debates within psychology, philosophy and literature about the implications of developments within the neurosciences, and the emerging fields of educational neuroscience, neuro-economics, and neuro-aesthetics also bear witness to a (...) 'neurological turn' which is currently taking place. Neuroscience and Critique is a ground-breaking edited collection which reflects on the impact of neuroscience in contemporary social science and the humanities. It is the first book to consider possibilities for a critique of the theories, practices, and implications of contemporary neuroscience. Bringing together leading scholars from several disciplines, the contributors draw upon a range of perspectives, including cognitive neuroscience, critical philosophy, psychoanalysis, and feminism, and also critically examine several key ideas in contemporary neuroscience, including: The idea of "neural personhood" Theories of emotion in affective neuroscience Empathy, intersubjectivity and the notion of "embodied simulation" The concept of an "emo-rational" actor within neuro-economics. The volume will stimulate further debate in the emerging field of interdisciplinary studies in neuroscience, and will appeal to researchers and advanced students in a range of disciplines including critical psychology, philosophy, and critical studies.

The long standing reign of psychology as the privileged partner of education has, arguably, now been superseded by the neurosciences. Given that this helped to drive the emergent field of neuroeducation, it is crucial to ask what changes in education, if anything does in fact change, when the hitherto hegemonic psychologising discourse is substituted for a neurological one. The primary contention of this paper is that with the neuro-turn a process of “neurologisation” has also been initiated, which can be analysed (...) by taking into account its genealogical predecessor, psychologisation. In doing so, I argue, one ultimately discerns a primordial incompatibility between education and neuroscience, one that can be traced back to the fundamental and problematic reflexivity of modern subjectivity itself, which the discipline of psychology was never able to wholly resolve. From here, I proceed with the argument that while the eagerness of the psy-sciences to embrace neuroscience testifies to how much psychology needs neurology, the neurosciences are structurally incapable of disconnecting from the paradigms of the psy-sciences. Following on from this proposition, other strong/weak factors are brought into the equation: strong/weak nature, strong/weak culture, strong/weak subjectivity and, most pertinently, strong/weak education. Finally, the critical question becomes: if education in itself needs to take recourse to both the psy-sciences and the neurosciences, then how can we begin to account for the fact that these sciences invariably end up becoming captured within educational discourses themselves; that is, the fact that teachers, parents, and pupils themselves are taught the key insights of neuropsychology.

Recent work in the history of science has questioned the Eurocentric nature of the field and sought to include a more global approach that would serve to displace center–periphery models in favor of approaches that take seriously local knowledge production. Historians of Iberian colonial science have taken up this approach, which involves reliance on indigenous knowledge traditions of the Americas. These traditions present a number of challenges to modern researchers, including availability and reliability of source material, issues of translation and (...) identification, and lack of systematization. This essay explores the challenges that emerged in the author’s attempt to compile a pre-contact Nahua pharmacopeia, the reasons for these challenges, and the ways they may – or may not – be overcome.

The practices of Galenic pharmacy that dominated the Western pharmaceutical tradition throughout the medieval and early modern periods generally eschewed methods of alchemical processing and the use of high heat. A unique 10th-century Arabic pharmaceutical treatise, the Kitab al Tasrif by al-Zahrāwī/Abulcasis, however, discussed thermo-chemical techniques of distillation, calcination, and sublimation at length and would go on to have a major impact on Galenic pharmacy. It included recipes, for example, for two highly important distilled substances – rosewater and Philosophers' Oil (...) – that were copied and revised in Latin texts from the later Middle Ages and early modern Spanish formularies. By the end of the 16th century, these recipes had formed the basis for two new categories of distilled medicines – distilled waters and distilled oils – in Galenic pharmacy. Their inclusion in the Galenic formulary indicates that apothecaries in the Latin West were familiar with and indeed practicing thermo-chemical operations during the medieval and early modern periods.

Resumen Se estudia comparativamente el desempeño de adultos mayores y de adultos jóvenes en una tarea concurrente que consiste en leer oraciones ecuacionales mientras, al mismo tiempo, se retienen en la memoria tres palabras. El propósito del experimento es averiguar si existe un efecto de las variables edad, memoria operativa, complejidad sintáctica e interferencia de una carga concurrente de memoria en el procesamiento y comprensión de oraciones de sintaxis compleja. El análisis estadístico multinivel realizado revela que tanto el procesamiento en (...) línea de las oraciones ecuacionales como su comprensión se ven afectados significativamente por la edad de los participantes cuando opera una carga de memoria concurrente. Las variables memoria operativa y complejidad sintáctica, por su parte, afectan también significativamente el desempeño de los sujetos, pero independientemente de su edad.The performance of older and young adults in a concurrent task -to read equational sentences while at the same time the subjects retain in memory three words- is comparatively studied. The purpose of the experiment is to find out if there is an effect of the variables of age, working memory, syntactic complexity and interference of a concurrent memory load processing on the comprehension of syntactically complex sentences. The multilevel statistical analysis reveals that both online processing of cleft sentences as their understanding is significantly affected by the age of participants when operating a concurrent memory load. The working memory variables and syntactical complexity, meanwhile, also significantly affect the performance of subjects, but regardless of age. (shrink)

Research has shown the importance of engaging in networking behaviors for employees’ career success. Networking behaviors can be seen as a proactive way of creating access to career-related social resources and we argue that this type of proactive career behaviors might be particularly relevant for freelancers who cannot depend on an organizational career system supporting their further development, yet whose careers are characterized by high levels of uncertainty and unpredictability. To date, however, our understanding of how freelancers, being a category (...) of workers that are deprived of an organizational context of support for career development, can safeguard their employability, is limited. Therefore, this study addresses this gap and investigates whether freelancers’ networking behaviors are positively associated with career outcomes, through the mediating role of the need for relatedness fulfillment and employability-enhancing competencies. Hypotheses are tested via Structural Equation Modelling using a sample of 1,874 freelancers from Belgium, France, Germany, the Netherlands and the United Kingdom. The results generally support our hypotheses, providing evidence for a significant association between networking behaviors and need for relatedness fulfillment, and between networking behaviors and employability-enhancing competencies. Moreover, we found a significant association between need for relatedness fulfillment and employability-enhancing competencies, being the mediators in our research model and the outcomes of career satisfaction and future career opportunities. Implications for career development in the contemporary workplace are discussed, with particular attention for need for relatedness fulfillment, employability, and sustainable careers of freelance workers.

Los niños con trastorno por déficit de atención con hiperactividad presentan alteraciones en el desarrollo de la función ejecutiva que se traducen en dificultades del control atencional y de la flexibilidad cognitiva. Considerando la complejidad de los procesos involucrados en la comprensión de lectura y el papel fundamental que en ellos cumple la función ejecutiva, puede esperarse que los niños con TDAH presenten diferencias en su desempeño lector en comparación con sus pares sin TDAH. El presente estudio, de carácter correlacional-predictivo, (...) tiene como propósito determinar si tales diferencias de comprensión lectora existen realmente y si es posible predecirlas a partir de la función ejecutiva. Para ello se seleccionaron 71 escolares de tercer y cuarto año de enseñanza básica y se les evaluó la habilidad de comprensión de lectura, el reconocimiento de palabras, la amplitud de la memoria de trabajo verbal, el control atencional y la velocidad de procesamiento. Con el fin de determinar qué variables tenían capacidad para predecir el nivel de comprensión de los escolares se aplicó un análisis de regresión logística binaria. Los resultados ponen en evidencia que el TDAH afecta significativamente el desempeño lector de los escolares y que las variables vinculadas a la función ejecutiva, especialmente la memoria de trabajo, son buenos predictores del rendimiento en comprensión de lectura.

Byun et al. describe how deaf signers deal with communication problems in first encounters with signers of different languages. They show that the basic Conversation Analytic repair mechanisms for dealing with verbal troubles are largely reproduced in gesture and sign, including details of turn‐taking structure, timing and form. This underlines the role of repair as a basic resource for linguistic and interactional creativity across modalities.

The Florilegium Coislinianum, from which we are editing the chapter dealing with words beginning with the letter ?, is a large Byzantine anthology, dating back to the 9th-10th cent. Its manuscript tradition has been exhaustively explored for the first time in this article and our edition is based on 11 manuscripts, dated from the 10th to the 14th cent. We also compared the Florilegium Coislinianum with the Sacra Parallela and the Loci Communes.

Humanitarian aid’s psycho-therapeutic turn in the 1990s was mirrored by the increasing emotionalization and subjectivation of fund-raising campaigns. In order to grasp the depth of this interconnectedness, this article argues that in both cases what we see is the post-Fordist production paradigm at work; namely, as Hardt and Negri put it, the direct production of subjectivity and social relations. To explore this, the therapeutic and mental health approach in humanitarian aid is juxtaposed with the more general phenomenon of psychologization. This (...) allows us to see that the psychologized production of subjectivity has a problematic waste-product as it reduces the human to Homo sacer, to use Giorgi Agamben’s term. Drawing out a double matrix of a de-psychologizing psychologization connected to a politicizing de-politicization, it will further become possible to understand psycho-therapeutic humanitarianism as a case of how, in these times of globalization, psychology, subjectivity and money are all interrelated.

A comparison is made between the scientific receptions of three proposed new members of the hominin phylogenetic tree: the first finds of Neanderthal Man, those of Homo erectus, and those of Homo floresiensis. In each case, the leading scientists of the moment of discovery heavily debated the finds and neglected the meaning of those finds. At least it took/will take one generation before the meaning of those finds were/will be accepted.

Although community is a core sociological concept, its meaning is often left vague. In this article it is pointed out that it is a social form that has deep connections with human social nature. Human social life and human social history can be seen as unflagging struggles between two contradictory behavioral modes: reciprocity and status competition. Relative to hunter-gatherer societies, present society is a social environment that strongly seduces to engage in status competition. But at the same time evidence increases (...) that communal living is strongly associated with well being and health. A large part of human behavior and of societal processes are individual and collective expressions of on the one hand succumbing to the seductions of status competition and one the other hand attempts to build and maintain community. In this article some contemporary examples of community maintaining, enrichment and building are discussed. The article concludes with a specification of structural conditions for community living and a short overview of ways in which the Internet affects these conditions. (shrink)

Milgram’s series of obedience experiments and Zimbardo’s Stanford Prison Experiment are probably the two best-known psychological studies. As such, they can be understood as central to the broad process of psychologization in the postwar era. This article will consider the extent to which this process of psychologization can be understood as a simple overflow from the discipline of psychology to wider society or whether, in fact, this process is actually inextricably connected to the science of psychology as such. In so (...) doing, the article will argue that Milgram’s and Zimbardo’s studies are best usefully understood as twin experiments. Milgram’s paradigm of a psychology which explicitly draws its subject into the frame of its own discourse can be said to be the precondition of Zimbardo’s claim that his experiment offers a window onto the crucible of human behaviour. This will be analysed by drawing on the Lacanian concepts of acting out and passage à l’acte. The question then posed is: if both Milgram and Zimbardo claim that their work has emancipatory dimensions — a claim maintained within mainstream psychology — does a close reading of the studies not then reveal that psychology is, rather, the royal road to occurrences such as Guantanamo and Abu Ghraib? The drama of a psychology which is fundamentally based on a process of psychologization is that it turns its subjects into homo sacer of psychological discourse. (shrink)
