The idea that one can 'soak up' someone else's mood or sense the tension in a room is familiar - as in 'negative energy'. This ability to borrow or share states of mind is now pathologized, as the author shows in relation to affective transfer in psychiatric clinics.

In my 1991 paper, AAnti-Individualism and Privileged Access,@ I argued that externalism in the philosophy of mind is incompatible with the thesis that we have privileged , nonempirical access to the contents of our own thoughts.¹ One of the most interesting responses to my argument has been that of Martin Davies (1998, 2000, and Chapter _ above) and Crispin Wright (2000 and Chapter _ above), who describe several types of cases to show that warrant for a premise does not always (...) transmit to a known deductive consequence of that premise, and who contend that this fact under-mines my argument for incompatibilism. I will try to show here that the Davies/Wright point about transmission of warrant does not adversely affect my argument. (shrink)

Cultural evolutionary theories define prestige as social rank that is freely conferred on individuals possessing superior knowledge or skill, in order to gain opportunities to learn from such individuals. Consequently, information provided by prestigious individuals should be more memorable, and hence more likely to be culturally transmitted, than information from non-prestigious sources, particularly for novel, controversial arguments about which preexisting opinions are absent or weak. It has also been argued that this effect extends beyond the prestigious individual’s relevant domain of (...) expertise. We tested whether the prestige and relevance of the sources of novel, controversial arguments affected the transmission of those arguments, independently of their content. In a four-generation linear transmission chain experiment, British participants recruited online read two conflicting arguments in favour of or against the replacement of textbooks by computer tablets in schools. Each of the two conflicting arguments was associated with one of three sources with different levels of prestige and relevance. Participants recalled the pro-tablets and anti-tablets arguments associated with each source and their recall was then passed to the next participant within their chain. Contrary to our predictions, we did not find a reliable effect of either the prestige or relevance of the sources of information on transmission fidelity. We discuss whether the lack of a reliable effect of prestige on recall might be a consequence of differences between how prestige operates in this experiment and in everyday life. (shrink)

The goal of the present study is to explore whether the affective states of a pedagogical agent in an online multimedia lesson yields different learning processes and outcomes, and whether the effects of affective PAs depend on the learners’ emotion regulation strategies and their prior knowledge. In three experiments, undergraduates were asked to view a narrated animation about synaptic transmission that included either a happy PA or a neutral PA and subsequently took emotions, motivation, cognitive outcomes tests. Across three (...) experiments, the happy PA group reported more positive emotions and higher level of motivation than the neutral PA group. Moreover, the happy PA prompted higher germane load than a neutral PA in Experiment 3. However, adding a happy PA to the screen did not improve learning performance. In addition, in Experiment 2, learners’ usage of emotion regulation strategies moderated the effectiveness of affective PA on positive emotions in learners. Specifically, happy PAs increased the positive emotions of students who used expressive suppression strategy but not those who used cognitive reappraisal strategy. In Experiment 3, the effectiveness of affective PAs was not moderated by learners’ prior knowledge. Results support the cognitive affective theory of learning with media that students are happier and more motivated when they learn from happy PAs than from neutral PAs. (shrink)

How environmental mechanical forces affect cellular functions is a central problem in cell biology. Theoretical models of cellular biomechanics provide relevant tools for understanding how the contributions of deformable intracellular components and specific adhesion conditions at the cell interface are integrated for determining the overall balance of mechanical forces within the cell. We investigate here the spatial distributions of intracellular stresses when adherent cells are probed by magnetic twisting cytometry. The influence of the cell nucleus stiffness on the simulated (...) nonlinear torque-bead rotation response is analyzed by considering a finite element multi-component cell model in which the cell and its nucleus are considered as different hyperelastic materials. We additionally take into account the mechanical properties of the basal cell cortex, which can be affected by the interaction of the basal cell membrane with the extracellular substrate. In agreement with data obtained on epithelial cells, the simulated behaviour of the cell model relates the hyperelastic response observed at the entire cell scale to the distribution of stresses and strains within the nucleus and the cytoskeleton, up to cell adhesion areas. These results, which indicate how mechanical forces are transmitted at distant points through the cytoskeleton, are compared to recent data imaging the highly localized distribution of intracellular stresses.

Mitochondria are essential subcellular organelles containing an extranuclear genome (mtDNA). Mutations in mtDNA have recently been identified as causing a variety of human hereditary diseases. In most of these cases, the tissues of the affected individual contain a mixture of mutant and normal mtDNA, with this ratio determining the severity of symptoms. Stochastic factors alone have generally been believed to determine this ratio. Jenuth et al.(1), however, examining mice that contain a mixture of mtDNA types, show evidence of strong selective (...) forces at work in favoring one mtDNA variant over another in some tissues.

This article introduces an agent-based and a system-dynamics model investigating the cultural transmission of frequent collective rituals. It focuses on social function and cognitive attraction as independently affecting transmission. The models focus on the historical context of early Christian meals, where various theoretically inspiring trends in cultural transmission of rituals can be observed. The primary purpose of the article is to contribute to theorizing about cultural transmission of rituals by suggesting a clear operationalization of their social (...) function and cognitive attraction. Furthermore, the article challenges recent trends in the field by providing a theoretically feasible model for how, under certain conditions, cognitive attraction can influence the transmission to a relatively greater extent than social function. In the system dynamics model we reproduce the results of our agent-based model while putting some of our basic operational assumptions under scrutiny. We consider approaching social function and cognitive attraction in isolation as a preliminary but necessary step in the process of creating more complex models of the cultural selection of rituals, where the two aspects will be combined to produce ritual forms with greater correspondence to real-world religious rituals.

This paper examines how coherence of the contents of evidence affects the transmission of probabilistic support from the evidence to the hypothesis. It is argued that coherence of the contents in the sense of the ratio of the positive intersection reduces the transmission of probabilistic support, though this negative impact of coherence may be offset by other aspects of the relations among the contents. It is argued further that there is no broader conception of coherence whose impact on (...) the transmission of probabilistic support is never offset by other aspects of the relations among the contents. The paper also examines reasons for the contrary impression that coherence of the contents increases the transmission of probabilistic support, especially in the special case where the hypothesis to evaluate is the conjunction of the contents of evidence.

This article proposes that the propagation of vibrations could serve as a better model for understanding the transmission of affect than the flow, circulation or movement of bodies by which it is most often theorized. The vibrations (or idiomatically ‘vibes’) among the sound system audience (or ‘crowd’) on a night out on the dancehall scene in Kingston, Jamaica, provide an example. Counting the repeating frequencies of these vibrations in a methodology inspired by Lefebvre’s rhythmanalysis results in a Frequency (...) Spectrogram. This ranges from the sociocultural frequencies of nightly, weekly and seasonal cycles and circulations of musical style and fashion, to the material frequencies of the amplitudes and timbres of sound itself, with reggae’s signature low-pitched bass-line, to the corporeal frequencies of the flesh and blood of the dancehall ‘crowd’, pulsating with heartbeats and kinetic dance rhythms. The vibration model then addresses the intensities of affect in terms of auditory amplitudes, as with sonic dominance; feelings as frequencies; and the distinctive meaning of affect as timbre. This aims to encourage the radical impulse of the idea of affect to abandon the traditional envelope of the autonomous, self-consistent, rational individual. The meaning of affect is thus located in the ratio, proportions and patterning of vibrations, that is, outside the discourse of emotions or representation of feelings. (shrink)

In the last number of CQ,, I mistakenly attributed to Professor Zuntz the view that P's exemplar was, before correction, the ‘parent’ of L. The possibility that the parent of L became, after corrections derived from its own parent , the parent of P is in fact considered by Zuntz only as an alternative to the hypothesis, propounded by him on p. 122 and set out in his stemma on p. 192, that the parent of P was a copy of (...) Λ and thus a brother of L. Regrettably, An Inquiry appeared too late for me to do it justice, with my article already in proof. In addition, I now draw attention to the following passages in An Inquiry as containing arguments which affect what I have written: pp. 13 ff. , 119 f. , and 118. (shrink)

In this article I examine an important episode in the growth of ‘mindfulness’ as a biomedical modality in Britain: the formation and establishment of Mindfulness-Based Cognitive Therapy (MBCT) by John Teasdale and his colleagues Mark Williams and Zindel Segal. My study, focusing on Teasdale’s contribution, combines ethnographic, oral historical and archival research to understand how mindfulness was disseminated or, to use a term sometimes used by mindfulness practitioners themselves, ‘transmitted’. Drawing on theoretical support from Max Weber, Michel Foucault and Gilles (...) Deleuze, I argue that transmission had a very specific form within the Buddhistic milieu that Teasdale occupied and within which he developed MBCT. To ‘transmit’ mindfulness was to transmit an experiential essence; a type of subjectivity that was seen as perennial, universal and radically distinct from its historical context. In tracing the recurring metaphysical, metaphorical and visual tropes of mindfulness and its transmission, I attempt to understand how Teasdale was embedded in both local and global networks of discourse and practice, and how his life and work contributed and depended upon an assemblage whose elements (institutional, technical, conceptual, textual) straddled empiricist psychology and religious mysticism. I also examine how authority, experience and knowledge were closely interwoven in the birth of British mindfulness, coming together to form an affectively compelling ‘diagram’ that shaped the way mindfulness was practiced and disseminated. In doing so, I aim to open up the possibility of studying the history of the human sciences from a new perspective: one which places an emphasis on the emotional impetus generated by metaphysical assumptions.

I argue that there is an affective injustice in gendered and racialized oppression. To account for this, we must deny the opposition of affect and intentionality often assumed in the philosophy of emotion and the affective turn: while affect and intentionality are not opposed in principle, affective intentionality may be refused uptake in oppressive practices. In section 1, I read Merleau‐Ponty’s theory of the body schema as a theory of affect that accommodates my account of affective injustice (...) and aligns with accounts of affect transmission and circulation in feminist philosophies of the affective turn. This is crucial for understanding Fanon’s contribution to the theory of the body schema, in which it is susceptible to historical‐racial “affective disorders.” In sections 2–4, I distinguish three types of affective injustice: affective marginalization, exploitation, and violence. In section 2 I develop an intersectional feminist account of this distinction drawing on Lorde and Lugones and raise questions about the limits of framing the issue of affective injustice in terms of intentionality as opposed to a more psychoanalytic conceptual vocabulary that accommodates the displacement of affective force. In sections 3 and 4, I explore these affective injustices through an analysis of Fanonian concepts, showing how the theory of the body schema can accommodate not only affective intentionality but also the oppressive disjunction of affect and intentionality, as well as forms of affective injustice that exceed the oppressive disabling of sense‐making and involve the exploitative and violent displacement of affective force.

The purpose of the present study was to compare differential functioning of Iranian English versus Persian teachers in responding to compliments and to investigate the possibility of sociolinguistic transmission of speech act of responding to compliments from English culture to native Iranian Persian speakers. Following Chen and Yang (2010), we hypothesized that exposure to English would affect the complimenting behavior of Persian speakers, leading to more acceptance of compliments compared to those with little or no exposure to English. (...) Participants of the study were 50 English teachers, regarded as “exposed-to-English” or E group, and 50 Persian teachers, considered as “unexposed-to-English” or U group. The participants’ age ranged from 20 to 35 and they were selected through non-randomized convenience sampling. A Discourse Completion Test (DCT) comprising eight complimenting situations was developed in two versions, i.e. English and Persian, in light of Mane’s (1983) taxonomy. The results revealed a significant difference in performance between groups and that Iranian English teachers’ Compliment Response (CR) behavior changed due to exposure to English and approached English culture. Further findings and implications are discussed in the paper. (shrink)

The symmetrical inter-displacements of corresponding blocks of text between strophes and antistrophes in lyrical odes, earlier proposed for A. Supp. 88–90 ∼ 93–95, 872–75 ∼ 882–84, and 906–7 ∼ 909–10, have affected all parts sung or spoken by the Egyptian herald in the amoibaion in Supp. 843–910. An ancestral text similar to a modern musical score, in which the corresponding lines of strophe and antistrophe run parallel with musical notation, could explain this type of corruption. Such a hypothetical ancestor in (...) the textual tradition would also explain apparent interpolations in Supp. 852 and 865 from 842 and 843. The corruptions may have arisen very early in the tradition, the hypothetical textual arrangement possibly being that of the author himself. (shrink)

The environment can have a long‐lasting influence on an individual's physiology and behavior. While some environmental conditions can be beneficial and result in adaptive responses, others can lead to pathological behaviors. Many studies have demonstrated that changes induced by the environment are expressed not only by the individuals directly exposed, but also by the offspring sometimes across multiple generations. Epigenetic alterations have been proposed as underlying mechanisms for such transmissible effects. Here, we review the most relevant literature on these changes (...) and the developmental stages they affect the most. We discuss current evidence for transgenerational effects of prenatal and postnatal factors on bodily functions and behavioral responses, and the potential epigenetic mechanisms involved. We also discuss the need for a careful evaluation of the evolutionary importance with respect to health and disease, and possible directions for future research in the field. (shrink)

Nietzsche’s relationship to his contemporaries, as expressed in his writings, was often figured by corporeal imagery evocative of disgust. For instance, in On the Genealogy of Morality Nietzsche declared himself to suffer from mankind—which he then proceeds to describe as “maggot”—or worm-like. Nietzsche’s philosophical project can be interpreted as a visceral protest against, and attempt to overcome, humanity. This paper argues that Nietzsche attempted through his writings to create a future community of like-constituted companions in his readers through a (...) class='Hi'>transmission of affect and education in taste. This would-be "community" is premised on a curious affective dialectic that seeks to transform disgust for humanity into a pure movement of self-creation. The socio-political effects of this dialectic of disgust will be examined alongside Nietzsche's co-option of images of purity, in order to evaluate his response to modern nihilism. (shrink)

BackgroundBayesian estimation with informative priors permits updating previous findings with new data, thus generating cumulative knowledge. To reduce subjectivity in the process, the present study emphasizes how to systematically weigh and specify informative priors and highlights the use of different aggregation methods using an empirical example that examined whether observed mother-adolescent positive and negative interaction behavior mediate the associations between maternal and adolescent internalizing symptoms across early to mid-adolescence in a 3-year longitudinal multi-method design.MethodsThe sample consisted of 102 mother-adolescent dyads. (...) Mothers and adolescents reported on their internalizing symptoms and their interaction behaviors were observed during a conflict task. We systematically searched for previous studies and used an expert-informed weighting system to account for their relevance. Subsequently, we aggregated the priors using three methods: linear pooling, logarithmic pooling, and fitting a normal distribution to the linear pool by means of maximum likelihood estimation. We compared the impact of the three differently specified informative priors and default priors on the prior predictive distribution, shrinkage, and the posterior estimates.ResultsThe prior predictive distributions for the three informative priors were quite similar and centered around the observed data mean. The shrinkage results showed that the logarithmic pooled priors were least affected by the data. Most posterior estimates were similar across the different priors. Some previous studies contained extremely specific information, resulting in bimodal posterior distributions for the analyses with linear pooled prior distributions. The posteriors following the fitted normal priors and default priors were very similar. Overall, we found that maternal, but not adolescent, internalizing symptoms predicted subsequent mother-adolescent interaction behavior, whereas negative interaction behavior seemed to predict subsequent internalizing symptoms. Evidence regarding mediation effects remained limited.ConclusionA systematic search for previous information and an expert-built weighting system contribute to a clear specification of power priors. How information from multiple previous studies should be included in the prior depends on theoretical considerations, and may also be affected by pragmatic considerations regarding the impact of the previous results at hand.

Limited distribution phenomena related to negation and negative polarity are usually thought of in terms of affectivity where affective is understood as negative or downward entailing. In this paper I propose an analysis of affective contexts as nonveridical and treat negative polarity as a manifestation of the more general phenomenon of sensitivity to (non)veridicality (which is, I argue, what affective dependencies boil down to). Empirical support for this analysis will be provided by a detailed examination of affective dependencies in Greek, (...) but the distribution of any will also be shown to follow from (non)veridicality.

This paper seeks to demonstrate the structural difference in communication of schizophrenia and autism. For a normal adult, spontaneous communication is nothing but the transmission of phantasía (thought) by means of perceptual objects or language. This transmission is first observed in a make-believe play of child. Husserl named this function “perceptual phantasía,” and this function presupposes as its basis the “internalized affection of contact” (which functions empirically in eye contact, body contact, or voice calling me). Regarding autism, because (...) of the innate lack of affection of contact, intersubjective perceptual phantasía does not occur spontaneously. Consequently, autistics do not engage in make-believe play but in stereotyped and solipsistic play. Without the formation of perceptual phantasía, there is no differentiation between phantasía and perception. For this reason, people with Asperger's syndrome consider conversation not an immediate communication of thought but a logical transmission of concepts. Schizophrenia is characterized by a distortion in the internalized affection of contact, resulting in a disturbance of perceptual phantasía, and this later is covered by various symptoms—for example, delusion as a pathological kind of communication of thought. This delusion is based on the pathological internalized affection of contact represented by a terrifying Other. (shrink)

When people retell stories, what guides their retelling? Most previous research on story retelling and story comprehension has focused on information accuracy as the key measure of stability in transmission. This paper suggests that there is a second, affective, dimension that provides stability for retellings, namely the audience affect of surprise. In a large-sample study with multiple iterations of retellings, we found evidence that people are quite accurate in preserving all degrees of surprisingness in serial reproduction – even (...) when the event that produced the surprisingness in the original story is dropped or changed. Thus, we propose that the preservation of affect is an implicit goal of retelling: not merely do retellers recall highly surprising events better, but rather they register all levels of surprisingness precisely and aim to surprise their implied audience to same degree. This study used 2,389 participants. (shrink)

An exploration of the production, transmission, and mutation of affective tonality—when sound helps produce a bad vibe.

The essay is concentrated on emotional affects caused by representation of violence in the case of Russia’s war against Ukraine and beyond. Instant accessibility to first-hand visual information created fertile soil for planting and then multiplying manipulative strategies of one or another political interest. Meanwhile, the demand for shocking content continues to steadily rise because it guarantees popularity, spectacle and even a form of pleasure. This, in turn, supports a very propagandistic version of reality where violence plays a central role (...) in the overall design and transmission of contents, which is driven by shock as an affective medium. Blind Spot, Gradual Loss of Vision and Speck in the Eye represent a body of works by Mykola Ridnyi, address the question of what potential response(s) could be given by artistic interventions understood as a dialectical and critical framework able to face and make visible the problem of dehumanization through violence?

This commentary focuses on affective structures and the main adaptive functions of shared narratives to fill the gaps of the Conviction Narrative Theory. The transmission of narratives among individuals in highly uncertain situations is irrevocably tainted by affects and anchored in collective memory. Narratives have important evolutionary functions for human beings under threat and act as the social glue that creates and strengthens social bonds among individuals.

This article interprets Teresa Brennan’s work on the forgetting of affect transmission in conjunction with Sylvia Wynter’s argument concerning the rise of Western Man through the dehumanization of native and African peoples. While not directly in dialogue, Wynter’s decolonial reading of Foucault’s epistemic ruptures enriches Brennan’s inquiry into this “forgetting,” given that callous, repeated acts of cruelty characteristic of Western imperialism and slavery required a denial of the capacity to sense suffering in others perceived as differently human. Supplementing (...) Brennan with Wynter, we can better describe the limits of sympathy discourses as resting on identification and perceived sameness. In turn, Brennan comes to Wynter’s defense in her call for a new science of plural cultures to redefine the human, which some have interpreted as a positivist misreading of Frantz Fanon. Brennan and Wynter alike have been criticized for their appeals to science; yet, I defend their respective proposals for social-scientific inquiry with support from Brennan’s response to the 1996 Sokal Hoax: the influence of the social on the biological body is, indeed, difficult to study, but this does not invalidate the inquiry as such.

Information changes as it is passed from person to person, with this process of cultural transmission allowing the minds of individuals to shape the information that they transmit. We present mathematical models of cultural transmission which predict that the amount of information passed from person to person should affect the rate at which that information changes. We tested this prediction using a function-learning task, in which people learn a functional relationship between two variables by observing the values (...) of those variables. We varied the total number of observations and the number of those observations that take unique values. We found an effect of the number of observations, with functions transmitted using fewer observations changing form more quickly. We did not find an effect of the number of unique observations, suggesting that noise in perception or memory may have affected learning. (shrink)

Active cultural transmission of fitness-enhancing behavior can be seen as a costly strategy: one for which its evolutionary stability poses a Darwinian puzzle. In this article, we offer a biological market model of cultural transmission that substitutes or complements existing kin selection-based proposals for the evolution of cultural capacities. We demonstrate how a biological market can account for the evolution of teaching when individual learners are the exclusive focus of social learning. We also show how this biological market (...) can affect the dynamics of cumulative culture. The model works best when it is difficult to have access to the observation of the behavior without the help of the actor. However, in contrast to previous non-mathematical hypotheses for the evolution of teaching, we show how teaching evolves, even when innovations are insufficiently opaque and therefore vulnerable to acquisition by emulators via inadvertent transmission. Furthermore, teaching in a biological market is an important precondition for enhancing individual learning abilities. (shrink)

In the Sociology of Emotion and Affect Studies, affects are usually regarded as an aspect of human beings alone, or of impersonal or collective atmospheres. However, feelings and emotions are only specific cases of affectivity that require subjective inner selves, while the concept of ‘atmospheres’ fails to explain the singularity of each individual case. This article develops a theory of social affect that does not reduce affect to either personal feelings or collective emotions. First, I use a (...) Spinozist understanding of the ‘body’ to conceptualize the receptivity and mutual constitution of bodies, to show how affects do not ‘belong’ to anybody; they are not solely attributable either to the human or to any kind of body alone, but emerge in situations of the encounter and interaction. Next I build upon Jean-Marie Guyau’s concept of transmissions to show how we can theorize affect as an emerging transmission between and among bodies. Finally, I demonstrate how we now have a complete conceptual frame for theorizing affect in relation to all bodies in any given social scene, the grand composition of which I call affectif. (shrink)

This article explores the relationship between the affective intensities of screen media and its potential to serve as an affective force for the transmission of intergenerational trauma. I explore how watching a documentary portraying historical atrocities that preceded the birth of the documentary’s viewers yet affected their lives in profound ways, is one of the manifold engagements in genealogy and memory work that seeks to know the past affectively. My focus is on Indisch viewers whose relatives suffered through various (...) atrocities that took place in Indonesia in the 20th century. By ethnographically exploring Indisch affective engagements with Joshua Oppenheimer’s documentary, The Act of Killing, I show how such engagements need to be analysed as occurring across human and non-human interactions and beyond the subject–object distinction. I argue that the affectivity of screen media that showcase instances of historical violence that have never received much public representation needs to be understood with particular historical contingencies. This article alerts us to how processes of getting to know the past affectively reveal the fragility of the embodied self in the wake of cataclysmic violence. (shrink)

Since the outbreak of the novel coronavirus disease at the beginning of December 2019, there have been more than 28.69 million cumulative confirmed cases worldwide as of 12th September 2020, affecting over 200 countries and regions with more than 920,463 deaths. The COVID-19 pandemic has been sweeping worldwide with unexpected rapidity. In this paper, a hybrid modelling strategy based on tessellation structure- configured SEIR model is adopted to estimate the scale of the pandemic spread. Building on the data pertaining to (...) the global pandemic transmission over the last six months around the world, key impact factors in the transmission and control procedure have been analysed, including isolation rate, number of the infected cases before taking prevention measures, degree of contact scope, and medical level, so as to capture the fundamental factor influencing the pandemic. The quantitative evaluation allowed us to illustrate the magnitude of risks of pandemic and to recommend appropriate national health policy of prevention measures for effectively controlling both intra- and interregional pandemic spread. Our modelling results clearly indicate that the early-stage preventive measures are the most effective action to be taken to contain the pandemic spread of the highly contagious nature of the COVID-19.

Schistosomiasis, a vector-borne chronically debilitating infectious disease, is a serious public health concern for humans and animals in the affected tropical and sub-tropical regions.

Global stability of the endemic equilibrium is carried out by constructing a suitable Lyapunov function. (...) Sensitivity analysis shows that the basic reproduction number is most sensitive to the model parameters related to the contaminated environment, namely: shedding rate of cercariae by snails, cercariae to miracidia survival probability, snails-miracidia effective contact rate and natural death rate of miracidia and cercariae. Numerical results show that when no intervention measures are implemented, there is an increase of the infected classes, and a rapid decline of the number of susceptible and exposed bovines and snails.

There are many narrations about the Stories of the Prophets in basic hadith, tafsir and historical sources. In addition to the Qur'an, some information about the stories of the prophets is contained in the Torah and the Bible. The stories of the Prophet were known to Jews and Christians before the advent of Islam. Even the Arabs of the jahiliyyah period had some knowledge about the parables. When the revelation about the stories of the Prophet was revealed, the polytheists were (...) extremely disturbed by it and "esâtîru'l-evvelîn" was used to describe these stories as the tales of the past tribes. Apart from the verses in the Qur'an about the stories of the Prophet, both the hadiths in the hadith sources and the narrations in the historical sources, some of this information was authentic information, while some of it consisted of fabricated information. Among these narrations, there are weak narrations such as Isrâiliyyât, as well as sound ones. It is important how the authors who wrote the works of Kasasu'l-Enbiyâ were affected by the hadiths in the main sources and whether they included these narrations in their works. Therefore, in this study, some hadiths related to the Stories of the Prophets in the Kitâbu'l-Anbiyâ section of Sahîhu'l-Bukhârî, which is one of the most important hadith works and accepted as the most reliable book after the Qur'an, were tried to be examined. In particular, some narrations that the authors of Kasasu'l-Enbiyâ's works were not included in their works, although they were mentioned in Sahîhu'l-Bukhârî, were discussed. In fact, there are many hadiths related to the subject in Sahihu'l-Bukhari. However, in this study, six narrations that were not mentioned by the authors of history, tafsir and Kasasu'l-Anbiya were mentioned. While referring to the aforementioned narrations, no analysis of the hadiths was made in order not to go beyond the scope of the subject and not to exceed the limits of the study. The reasons why these narrations are not references in the Kasasu'l-Anbiya literature are emphasized. Thus, these narrations, which are not mentioned in Kasasu'l-Enbiya's works but are mentioned in the Kitabu'l-Anbiyâ section of Sahîhu'l-Bukhârî, are examined and their source status for the stories of the Prophet is examined.

The virulence of a virus is determined by its ability to adversely affect the host cell, host organism or population of host organisms. Influenza A viruses have been responsible for four pandemics of severe human respiratory disease this century. Avian species harbour a large reservoir of influenza virus strains, which can contribute genes to potential new pandemic human strains. The fundamental importance of understanding the role of each of these genes in determining virulence in birds and humans was dramatically (...) emphasised by the recent direct transmission of avian influenza A viruses to humans, causing fatal infection but not community spread. An understanding of the factors involved in transmission between avian and mammalian species should assist in the development of better surveillance strategies for early recognition of influenza A virus strains having human pandemic potential, and possibly in the design of anti‐viral strategies.

In lieu of an abstract, here is a brief excerpt of the content:Vertical Transmission:The Patient, the Student, the TeacherMiguel PaniaguaHe did not ask for this fate, nor did he deserve it, particularly considering the tragic circumstances. Lì presented to the campus health provider one month prior with fatigue, abdominal pain, and jaundice. He and his parents immigrated to the United States from China when he was a child. He was well aware that he had hepatitis B from what is (...) termed "vertical transmission." His mom unknowingly passed on this virus to him during her pregnancy. In most countries with a high prevalence of the virus, prenatal screening is routinely undertaken, and prophylaxis administered. I am not certain this occurred in Lì's case and at this point it did not matter. Lì knew he would live with this for the duration of his life. In fact, he told me he had gone his whole life to this point without any symptoms whatsoever. What is known about chronic hepatitis B infection is that in most people affected, it can be considered a chronic disease where most live a long full life. The risk of advancing to liver cirrhosis or cancer in general is low. This unfortunately was not the case with Lì.What transpired was what they most feared. As he was studying for his final exams, Lì endured days of worsening fatigue, malaise, and nausea. He noticed his skin was a tinge of yellow and he was having some itching that was unusual. He noticed his clothes fitting more loosely and found he had unintentionally lost twenty pounds. He visited the campus health center and after a series of tests and imaging studies, Lì was diagnosed with advanced hepatocellular carcinoma, an unfortunate sequela of this chronic infection. It was then that he put school on hold and returned home to get further care.I first met Lì in the hospital as a consultant for the palliative medicine service. "He won't listen." "He is so difficult." "He is in denial." These were examples of some of the care team's exasperated assessments of his demeanor as a patient. What I did not realize prior to visiting him the first time was that Lì was a pre-clinical medical student. When I first met him, he did not want to talk very much; he was preoccupied and distant. In retrospect, I can see that he was suffering on so many levels. His appearance was gaunt and cachectic. The lights in the room cast shadows in the concave areas of his temples and his collarbones were the most prominent feature of his torso through his hospital gown. He glowed yellow from jaundice. When I examined him on this first visit, I noticed that his liver, a now grossly enlarged hard and nodular structure, occupied most of his abdomen. I found that speaking to him as a colleague, even calling him "doctor," helped him feel respected and enabled me to build rapport with him. At one point, I described to him the findings I felt in his abdomen. "I can palpate the edge of your liver here, what seems to be eight centimeters below your costal margin. There are many palpable nodularities on the ventral surface." It was at this point I invited him to palpate what I was feeling. I gently guided his own hand over his abdomen and noticed him studying the features as if they were not his own, like a skilled diagnostician.Over the course of three weeks, I visited with Lì when I was on service. The last time I saw him, he had declined rapidly, his disease progressing [End Page 17] cruelly, and he was very short of breath and becoming more somnolent. I noticed his mother in the room, standing by his bed, and crying inconsolably as he lay suffering. I felt deep anguish and remorse, wondering if she said these words to herself "It is all my fault," considering the source of his initial illness. I cannot even imagine.As I assisted the team in titrating his comfort medications, I sat with him. He shook my hand with all the strength left that he could muster and said, "you are a good doctor."

What goods are produced by affective labor? And at what cost—are there uniquely affective costs to this sort of production? If we assume that, like any variety of labor, affective labor has the potential for exploitation, we should ask what risks of exploitation are unique to it. Are these dangers of paid, commodified affective labor only? How should we understand the political economy organized around the production and circulation of affects and the racialization and gendering of affective labor?In this article, (...) I suggest that in order to understand the risks of exploitation indigenous to affective labor, we must consider the way in which the production of affects functions according to a logic of transmission...

This study focused on value transmission in the family and assessed adolescents’ acceptance of the values their parents want to transmit to them (socialisation values), identifying some factors that may affect the level of acceptance. Specifically, actual value agreement between parents, parental agreement as perceived by adolescents, parent–child closeness and promotion of child’s volitional functioning, were considered as predictors. Participants were 381 family triads (father, mother and adolescent child) from northern Italy; the adolescents (46.2% male) were all high‐school (...) students from 15 to 19 years of age. Both parents and their children filled out self‐report questionnaires. Findings showed a moderate level of acceptance in families, suggesting the presence of similarities as well as differences between parents’ socialisation values and adolescents’ personal values. All the predictors considered except parents’ actual agreement, were found to be significantly and positively related to acceptance. Implications for moral development are discussed and suggestions for education and future research are provided. (shrink)

Similar to parasites, malignant cells exploit the host for energy, resources and protection, thereby impairing host health and fitness. Although cancer is widespread in the animal kingdom, its impact on life history traits and strategies have rarely been documented. Devil facial tumour disease, a transmissible cancer, afflicting Tasmanian devils, provides an ideal model system to monitor the impact of cancer on host life-history, and to elucidate the evolutionary arms-race between malignant cells and their hosts. Here we provide an overview of (...) parasite-induced host life history adaptations, then both phenotypic plasticity of LH responses and changes in allele frequencies that affect LH traits of Tasmanian devils in response to DFTD are discussed. We conclude that akin to parasites, cancer can directly and indirectly affect devil LH traits and trigger host evolutionary responses. Consequently, it is important to consider oncogenic processes as a selective force in wildlife. Exposure to transmissible cancer cells, i.e., Tasmanian devil facial tumour cells, can cause changes to life history traits either as the result of phenotypic plasticity in response to exposure during the lifetime of the individual or as the result of evolutionary change in LH traits due to selection over generations.Photo credits: Frédéric Thomas, Sarah Peck, Geordie Jennings.

Malaria is a Plasmodium parasitic disease transmitted by infected female Anopheles mosquitoes. Climatic factors, such as temperature, humidity, rainfall, and wind, have significant effects on the incidence of most vector-borne diseases, including malaria. The mosquito behavior, life cycle, and overall fitness are affected by these climatic factors. This paper presents the results obtained from investigating the optimal control strategies for malaria in the presence of temperature variation using a temperature-dependent malaria model. The study further identified the temperature ranges in four (...) different geographical regions of sub-Saharan Africa, suitable for mosquitoes. The optimal control strategies in the temperature suitable ranges suggest, on average, a high usage of both larvicides and adulticides followed by a moderate usage of personal protection such as bednet. The average optimal bednet usage mimics the solution profile of the mosquitoes as the mosquitoes respond to changes in temperature. Following the results from the optimal control, this study also investigates using a temperature-dependent model with insecticide-sensitive and insecticide-resistant mosquitoes the impact of insecticide-resistant mosquitoes on disease burden when temperature varies. The results obtained indicate that optimal bednet usage on average is higher when insecticide-resistant mosquitoes are present. Besides, the average bednet usage increases as temperature increases to the optimal temperature suitable for mosquitoes, and it decreases after that, a pattern similar to earlier results involving insecticide-sensitive mosquitoes. Thus, personal protection, particularly the use of bednets, should be encouraged not only at low temperatures but particularly at high temperatures when individuals avoid the use of bednets. Furthermore, control and reduction of malaria may be possible even when mosquitoes develop resistance to insecticides. (shrink)

This article explores the psychological logics underpinning key perspectives in the ‘turn to affect’. Research on affect raises questions about the categorization of affective states, affective meaning-making, and the processes involved in the transmission of affect. I argue that current approaches risk depopulating affecting scenes, mystifying affective contagion, and authorizing questionable psychobiological arguments. I engage with the work of Sedgwick and Frank, Thrift, and Ahmed to explore these points and suggest that the concept of affective practice (...) offers a more promising social psychological grounding. Notions of affective practice are more commensurate with trends in contemporary psychobiology, explain the limits on affective contagion, and emphasize relationality and negotiation, attentive to the flow of affecting episodes. A practice approach positions affect as a dynamic process, emergent from a polyphony of intersections and feedbacks, working across body states, registrations and categorizations, entangled with cultural meaning-making, and integrated with material and natural processes, social situations and social relationships.

Most philosophers believe that testimony is not a fundamental source of knowledge, but merely a way to transmit already existing knowledge. However, Jennifer Lackey has presented some counterexamples which show that one can actually come to know something through testimony that no one ever knew before. Yet, the intuitive idea can be preserved by the weaker claim that someone in a knowledge-constituting testimonial chain has to have access to some non-testimonial source of knowledge with regard to what is testified. But (...) even this weaker claim has a counterexample which I develop in close connection with a safety-account of knowledge. Thus, testimonial statements can sometimes enable us to know something for which none of our informants has any source of knowledge available. I conclude that my counterexample nevertheless does not affect the core of our intuitions about testimony, although it establishes that testimony can indeed be a fundamental source of knowledge.

Many survivors of the Holocaust have carried feelings of shame related to having survived this horrific event. This paper traces a genealogy of shame by exploring the sources of shame that have haunted survivors, and how these have manifested themselves in their lives and the lives of their children. Arguing that the intergenerational transmission of shame has reinforced a culture of silence among survivors and their children, this paper calls for a reconceptualizing of the afterlife of the Holocaust, which (...) leverages shame as a powerful piece of remembering and understanding the Holocaust.

The serotonin transporter plays an important role in regulating serotonergic transmission via removal of serotonin from synaptic clefts. Alterations in 5-HTT expression and subsequent 5-HT transmission have been found to be associated with changes in behaviour, such as fearfulness or activity, in humans and other vertebrates. In humans, alterations in 5-HTT expression have been suggested to be able to lead to better learning performance, with more fearful persons being better at learning. Similar effects of the variation in the (...) 5-HTT on fearfulness have been found in chickens, and in this study, we investigated effects on learning. Therefore, we tested 52 adult laying hens, differing in their functional 5-HTT genotype in an operant learning paradigm in three different phases and in a tonic immobility test for fearfulness. We found that the 5-HTT polymorphism affects the initial learning performance of laying hens, with homogeneous wild-type hens being the slowest learners, and the most fearful birds. W/W hens, showed significantly more choices to solve the initial learning task and had the highest latencies in a tonic immobility test, indicating the highest fearfulness. Our results provide interesting first insights into the role of 5-HTT in chickens and its sensitive interaction with the environment. We further suggest that the 5-HTT gene can be an interesting target gene for future breeding strategies as well as for further experimental studies. (shrink)

In agreement with Behrendt & Young (B&Y), we considered the role of perception disturbances in schizophrenia in our first clinical approaches, using the Bender test with schizophrenic patients. Following this, we reproduced nuclear symptoms of schizophrenia in animal models, showing that perceptual disturbances, acquisition disturbances, and decrease in affective levels can be induced by glutamatergic blockade within the nucleus accumbens septi. Our results link the proposed corticostriatal dysfunction with the thalamocortical disturbances underlying perceptual problems reviewed by B&Y.

The Historia Novella is a key source for the succession dispute between King Stephen and the Empress Matilda which brought England to civil war in the twelfth century. William of Malmesbury was the doyen of the historians of his day. His account of the main events of the years 1126 to 1142, to some of which he was an eyewitness, is sympathetic to the empress's cause, but not uncritical of her. Edmund King offers a complete revision of K. R. Potter's (...) edition of 1955, retaining only the translation, which has been amended in places. Not only is this a new edition but it offers a new text, arguing that what have earlier been seen as William of Malmesbury's final revisions are not from his hand. Rather they seem to come from somewhere in the circle of Robert of Gloucester, the empress's half-brother, to whom the work is dedicated. In this way the work raises important questions concerning the transmission of medieval texts. (shrink)

The Continuous Parameter Estimation Model is applied to develop individual genomic-level heritabilities for the latent hierarchical structure and developmental dynamics of Life History (LH) strategy LH strategies relate to the allocations of bioenergetic resources into different domains of fitness. LH has moderate to high population-level heritability in humans, both at the level of the high-order Super-K Factor and the lower-order factors, the K-Factor, Covitality Factor, and General Factor of Personality (GFP). Several important questions remain unexplored. We developed measures of genome-level (...) heritabilities employing an American sample of 316 monozygotic (MZ) and 274 dizygotic (DZ) twin dyads and a Swedish sample of 863 MZ and 475 DZ twin dyads. This novel heritability index measures individual genetic transmissibility, therefore opening new avenues for analyzing complex interactions among heritable traits inaccessible to standard structural equations methods. For these samples: (1) moderate to high heritability of factor loadings of Super-K on its lower-order factors is demonstrated, evidencing biological preparedness, genetic accommodation, and the gene-culture coevolution of biased epigenetic rules of development; (2) moderate to high heritability of the magnitudes of the effect of the higher-order factors upon their loadings on their constituent factors, evidencing genetic constraints upon phenotypic plasticity; and (3) that heritability of the LH factors, of factor loadings, and of the magnitudes of the correlations among factors are weaker among those with slower LH speeds, demonstrating that inter-individual variation in transmissibility is a function of individual socioecological selection pressures.

Focus on the way in which cultural variants affect other variants' probabilities of transmission in modeling and empirical work can enrich Kline's conceptualization of teaching. For example, the problem of communicating complex cumulative culture is an adaptive problem; teaching methods that manage transmission so that acquisition of some cultural variants increases the probability of acquiring others, provide a partial solution.

Teresa Brennan was born in 1952 in Australia and died in South Florida, following a hit-and-run car accident in December 2002. In the ten years between her doctorate and her death, Brennan published five monographs, the most famous posthumously. The Transmission of Affect begins with a question that readers often remember: “Is there anyone who has not, at least once, walked into a room and ‘felt the atmosphere’?” Here and throughout her work, Brennan challenges the self-contained subject of (...) Western modernity, whose affects are presumed to be possessions of that self, underscoring the historical emergence of this egoic construction.I never met Teresa Brennan; I did not know her name until a decade after she...

Are emotions internal episodes – psychical or neurological – as is often claimed? Some certainly are; but I maintain that an important class of emotions are “peripheral”; by this I mean that they consist in what we pick up from others’ expressions of their emotions in words, gestures, or actions – or from surrounding circumstances of various sorts. These expressions and circumstances contain affect clusters that manifest themselves to us exophanously, literally “showings-forth.” I explore both of these basic situations (...) of “the transmission of affect”. I also present an abbreviated periphenomenological description of various ways in which emotions have their own peculiar edges, thereby correcting and supplementing the common conception that edges inhere only in physical objects.

Drawing on recent findings, this study examines whether valence concordant electromyography (EMG) responses can be explained as an unconditional effect of mere stimulus processing or as somatosensory simulation driven by task-dependent processing strategies. While facial EMG over the Corrugator supercilii and the Zygomaticus major was measured, each participant performed two tasks with pictures of album covers. One task was an affective evaluation task and the other was to attribute the album covers to one of five decades. The Embodied Emotion Account (...) predicts that valence concordant EMG is more likely to occur if the task necessitates a somatosensory simulation of the evaluative meaning of stimuli. Results support this prediction with regard to Corrugator supercilii in that valence concordant EMG activity was only present in the affective evaluation task but not in the non-evaluative task. Results for the Zygomaticus major were ambiguous. Our findings are in line with the view that EMG activity is an embodied part of the evaluation process and not a mere physical outcome. (shrink)

This article introduces a satellite technology, High Resolution Picture Transmission (HRPT), for a science activity. HRPT is a digital data stream transmitted from environmental satellites. The HRPT imagery is capable of providing real-time studies of regional geology, glacial processes, atmospheric processes, ocean circulation, coastal processes, hydrology, and so on. Obtaining and manipulating HRPT data creates a variety of exciting experiences in science classrooms. A Science and Technology for Individuals, Societies, and the Environment (STISE) teaching model was developed to use (...) satellite technologies for science activities. STISE is a conceptual model for addressing key cognitive and affective parameters when designing science lessons. STISE is designed to encourage students to understand science and technology from their levels of cognition, then relate their understanding to the environment, levels of societies, and their lives. Relationships among science, technology, and society become both obvious and interesting to students as they process and interpret the HRPT imagery. (shrink)
