In an earlier paper in Theoria, I discussed an argument based on the idea of “soul-switching” that attempted to undermine the immaterialist account of human beings. The present paper deals with a parity argument against that argument in which the idea of “body-switching” plays a pivotal role. I call these two arguments, that have been reported by Razi (d. 1210), respectively “the soul-switching argument” and “the body-switching argument”. After some introductory remarks, section 2 of the paper (...) describes the structure of the latter argument. Section 3 considers some philosophical discussions in the ancient, modern, and contemporary eras in which the idea of body-switching (or some similar conception) plays a major role. In the following section 4, some criticisms of the argument are discussed and a general response that is meant to cover a broad range of objections is considered. This paper shows that the body-switching argument reported by Razi is a methodological antecedent of several contemporary arguments in defence of substance dualism. (shrink)

In recent years, artificial intelligence has made significant progress, leading to a wide variety of applications, such as speech recognition, product recommendations, language translation, and many other applications. Although gender equality and artificial intelligence can be considered separate fields, they are closely related and mutually influence each other. The purpose of this paper is to outline various aspects of relationship between gender equality and artificial intelligence, to identify interrelationship between them, and to present challenges and possible solutions to problems arising (...) from their connection. This text will present the issue of gender equality in the development of artificial intelligence, but also the impact of artificial intelligence on gender equality; challenges and possible solutions, successful examples and case studies, legislation and policies supporting gender balance in artificial intelligence, the impact of gender equality on quality and innovation in artificial intelligence; the future of dynamics of development of relationship of gender equality and artificial intelligence.

Code switching is defined as the use of two or more languages or varieties of language in conversation. It is a general phenomenon in Pakistani society. This research was conducted through a qualitative descriptive method; it produces descriptive data in the form of code switched sentences from editorial of Urdu newspaper. In this research paper I discussed code switching in editorial of an Urdu newspaper. Daily Khabrain Newspaper was selected for this purpose. One week newspapers were collected for (...) research from 1st January, 2020 to 7th January, 2020 to analyze code switching in editorial. In this research paper I discussed code switching in editorial of an Urdu newspaper. Aims and Objectives are; in this research paper I discussed code switching in editorial of an Urdu newspaper. Research Question was what type of code switching is in editorial in Daily Khabrain Newspaper? Daily Khabrain Newspaper from first January 2020 to 7th January 2020 was collected for the analysis of language or code switching and its type in editorial. Through the analysis of data of newspaper it can be concluded that the type of code switching was intra sentential, word code switching and total integrated Urdu. (shrink)

Inducing the rubber hand illusion (RHI) requires that participants look at an imitation hand while it is stroked in synchrony with their occluded biological hand. Previous explanations of the RHI have emphasized multisensory integration, and excluded higher cognitive functions. We investigated the relationship between the RHI and higher cognitive functions by experimentally testing task switch (as measured by switch cost) and mind wandering (as measured by SART score); we also included a questionnaire for attentional control that comprises two subscales, attention-shift (...) and attention-focus. To assess experience of RHI, the Botvinick and Cohen (1998) questionnaire was used and illusion onset time was recorded. Our results indicate that rapidity of onset reliably indicates illusion strength. Regression analysis revealed that participants evincing less switch cost and higher attention-shift scores had faster RHI onset times, and that those with higher attention-shift scores experienced the RHI more vividly. These results suggest that the multi-sensory hypothesis is not sufficient to explain the illusion: higher cognitive functions should be taken into account when explaining variation in the experience of ownership for the rubber hand.

Theories of embodied cognition hold that the conceptual system uses perceptual simulations for the purposes of representation. A strong prediction is that perceptual phenomena should emerge in conceptual processing, and, in support, previous research has shown that switching modalities from one trial to the next incurs a processing cost during conceptual tasks. However, to date, such research has been limited by its reliance on the retrieval of familiar concepts. We therefore examined concept creation by asking participants to interpret modality-specific (...) compound phrases (i.e., conceptual combinations). Results show that modality switching costs emerge during the creation of new conceptual entities: People are slower to simulate a novel concept (e.g., auditory jingling onion) when their attention has already been engaged by a different modality in simulating a familiar concept (e.g., visual shiny penny). Furthermore, these costs cannot be accounted for by linguistic factors alone. Rather, our findings support the embodied view that concept creation, as well as retrieval, requires situated perceptual simulation. (shrink)

A fundamental property of emotional responses is a change in action tendencies that allow the individual to cope with the situation. Most basically, there are two types of behaviour one can switch to when responding emotionally: approach or withdrawal. The present study examined whether the ability to switch to approach or withdrawal depends on the type of behaviour shown before. Using familiar (Experiment 1) and unfamiliar (Experiment 2) neutral stimuli, we first show that switching from approach to withdrawal is (...) generally easier than vice versa. In Experiment 3, we demonstrate that this holds true even when participants respond to emotional stimuli that typically elicit strong approach or withdrawal tendencies. These results indicate that there is a fundamental asymmetry in the ability to switch from approach to withdrawal or vice versa. As shown in Experiment 3, this asymmetry may represent a serious confound in many previous studies examining the link between stimulus valence and associated action tendencies, suggesting that the link between positive stimuli and approach tendencies may be stronger, and the link between negative stimuli and withdrawal tendencies weaker, than previously believed.

Formal methods developed for modeling levels of selection problems have recently been applied to the investigation of major evolutionary transitions. We discuss two new tools of this kind. First, the ‘near-variant test’ can be used to compare the causal adequacy of predictively equivalent representations. Second, ‘state-variable gestalt-switching’ can be used to gain a useful dual perspective on evolutionary processes that involve both higher and lower level populations.

John Searle and Susanna Siegel have argued that cases of aspect‐switching show that visual experience represents a richer range of properties than colours, shapes, positions and sizes. I respond that cases of aspect‐switching can be explained without holding that visual experience represents rich properties. I also argue that even if Searle and Siegel are right, and aspect‐switching does require visual experience to represent rich properties, there is reason to think those properties do not include natural‐kind properties, such (...) as being a tomato.

The contentious question of bilingual processing cost may be recast as a fresh question of code-switching (CS) strategies—quantitative preferences and structural adjustments for switching at particular junctures of two languages. CS strategies are established by considering prosodic and syntactic variables, capitalizing here on bidirectional multi-word CS, spontaneously produced by members of a bilingual community in northern New Mexico who regularly use both languages (Torres Cacoullos and Travis, 2018). CS strategies become apparent by extending the equivalence constraint, which states (...) that bilinguals avoid CS at points of word placement conflict (Poplack, 1980), to examine points of inconsistent equivalence between the languages. Such sites of variable equivalence are junctures where the word strings of the two languages are equivalent only sometimes due to language-internal variable structures. A case in point for the English-Spanish language pair is the boundary between main and complement clauses, where a conjunction occurs always in Spanish but variably in English. The prosodic distancing strategy is to separate the juncture of the two languages. Here the complement clause appears in a different prosodic unit from the main clause, disproportionately as compared both with monolingual benchmarks and with bilinguals' own unilingual English and Spanish. Prosodic distancing serves to mitigate variable equivalence. The syntactic selection strategy is to opt for the variant that is more quantitatively available and more discourse neutral. Here the preference is for the Spanish complementizer que—regardless of main or complement clause language— which is the more frequent option in bilinguals' combined experience in both their languages, whereas English complementizer that is subject to a number of conditioning factors. Syntactic selection serves to restore equivalence at sites of variable equivalence. Discovery of community CS strategies may spur reconsideration of processing cost as a matter of relative difficulty, which will depend on bilinguals' prosodic and syntactic choices at particular CS sites.

Deciphering how DCAFs (DDB1‐CUL4 Associated Factors) modulate a broad spectrum of cellular processes, including cell cycle progression and maintenance of genomic integrity is critical to better understand cellular homeostasis and diseases. Cells contain more than 100 DCAFs that associate with the Cullin‐Ring Ubiquitin Ligase 4 (CRL4) complex that target specific protein substrates for degradation. DCAFs are thought to act as substrate receptors that dictate the specificity of the ubiquitination machinery (“catalytic DCAFs”). However, recent studies have suggested that some DCAFs might (...) play a different role by targeting CRL4 complexes to distinct cellular compartments (“structural DCAFs”). Once localized to their correct cellular domains, these CRLs dissociate from the structural DCAFs prior to their association with other, substrate‐specific catalytic DCAFs. Thus, we propose that DCAF switches can provide a mechanistic basis for the degradation of proteins that regulate cell growth and proliferation at precise points in space and time. (shrink)

This article deals with an argument reported by Razi (d. 1210) that attempted to undermine the immaterialist position about human nature. After some introductory remarks and explanation of the conceptual background, the article analyses the structure of the argument, with special attention to the idea of soul-switching.’ Some comparisons are made between the argument reported by Razi and a number of arguments from modern and contemporary eras of philosophy. One section is devoted to the critique of the argument and (...) its conceptual basis. This article shows that the argument reported by Razi is a methodological antecedent of a family of contemporary epistemological arguments against substance dualism. It is also shown that discussion of the argument could be useful to highlight a weakness in some, but not all, versions of immaterialism about human nature. (shrink)

The attempt to model the structure of consciousness in split-brain subjects is ongoing. This paper concerns the recently proposed ?switch model? of split-brain consciousness, according to which a split-brain subject possesses only a single stream of consciousness, unified at and across time, that shifts from one hemisphere to the other from moment to moment. The paper argues that while the central explanatory element of the switch model may account for some aspects of split-brain consciousness, the best general picture of split-brain (...) consciousness is still offered by some version of the ?conscious duality model.?

This discussion takes up an attack by Jerrold Aronson (seconded by Rom Harre) on the use made by Norwood R. Hanson of the Gestalt-Switch Analogy in the philosophy of science. Aronson's understanding of what is implied in a gestalt switch is shown to be flawed. In his endeavor to detach conceptual understanding from perceptual identification he cites several examples, without realizing the degree to which such gestalt switches can affect conceptualizing or how conceptualizing can affect gestalts. In particular, he has (...) not confronted the possibility of such gestalt selection being involved in the basic identification of what we term "entities". (shrink)

Recent models of the conceptual system hold that concepts are grounded in simulations of actual experiences with instances of those concepts in sensory-motor systems (e.g., Barsalou, 1999, 2003; Solomon & Barsalou, 2001). Studies supportive of such a viewhave shown that verifying a property of a concept in one modality, and then switching to verify a property of a different concept in a different modality generates temporal processing costs similar to the cost of switching modalities in perception. In addition (...) to non-emotional concepts, the present experiment investigated switching costs in verifying properties of positive and negative (emotional) concepts. Properties of emotional concepts were taken from vision, audition, and the affective system. Parallel to switching costs in neutral concepts, the study showed that for positive and negative concepts, verifying properties from different modalities produced processing costs such that reaction times were longer and error rates were higher. Importantly, this effect was observed when switching from the affective system to sensory modalities, and vice-versa. These results support the embodied cognition view of emotion in humans. (shrink)

Based on content externalism, the question of whether self-knowledge is authoritative or not has launched a real controversy in the philosophy of mind. Boghossian proposed slow switching argument in defense of incompatibility of the two views. This argument has been criticized by some philosophers through different approaches. Vahid is one of them. He claimed that Boghossian's argument appeals to some controversial assumptions without which it cannot achieve its conclusion. In this article, I criticize Vahid's response to slow switching (...) argument and show that self-knowledge in Vahid's response differs in having authority and therefore in function from that of Boghossian.

This study proposes a novel fractional-order sliding-mode control strategy with robust switching gain to achieve reliable and high quality of wind-powered microgrid systems. Three fractional-order sliding mode controllers are designed to generate continuous control signals and regulate the outer DC-link voltage loop and inner current loop in the grid-side inverters. High robustness and stability of the grid-side inverter can be guaranteed even in the presence of parameter variations and external disturbances. Owing to the fractional-order sliding manifold and fractional-order integral (...) control law, the chattering is attenuated. The fractional-order robust adaptive switching gain is designed to avoid overestimating the upper bound of matched/unmatched uncertainties, save the control energy, and guarantee the rapidity and robustness of the convergence. Simulations validate the proposed method. (shrink)

Recent advancements in developmental biology enable the creation of embryo-like structures from human stem cells, which we refer to as human embryo-like structures (hELS). These structures provide promising tools to complement—and perhaps ultimately replace—the use of human embryos in clinical and fundamental research. But what if these hELS—when further improved—also have a claim to moral status? What would that imply for their research use? In this paper, we explore these questions in relation to the traditional answer as to why human (...) embryos should be given greater protection than other (non-)human cells: the so-called Argument from Potential (AfP). According to the AfP, human embryos deserve special moral status because they have the unique potential to develop into persons. While some take the development of hELS to challenge the very foundations of the AfP, the ongoing debate suggests that its dismissal would be premature. Since the AfP is a spectrum of views with different moral implications, it does not need to imply that research with human embryos or hELS that (may) have ‘active’ potential should be completely off-limits. However, the problem with determining active potential in hELS is that this depends on development passing through ‘potentiality switches’ about the precise coordinates of which we are still in the dark. As long as this epistemic uncertainty persists, extending embryo research regulations to research with specific types of hELS would amount to a form of regulative precaution that as such would require further justification.

In the present study, we use a training design in two experiments to examine whether bilingual language switching facilitates two components of cognitive control, namely monitoring and inhibitory control. The results of Experiment 1 showed that training in language switching reduced mixing costs and the anti-saccade effect among bilinguals. In Experiment 2, the findings revealed a greater decrease of mixing costs and a smaller decrease of the anti-saccade effect from pre- to post-training for the language switching training (...) group compared to the L2 training group. Overall, the results suggest that extensive exercise in monitoring and inhibitory control among languages in an experimental setting may enhance the corresponding components of cognitive control. We discuss these findings in the context of the relationship between bilingual language control and executive control. (shrink)

Organisations that design and deploy artificial intelligence (AI) systems increasingly commit themselves to high-level, ethical principles. However, there still exists a gap between principles and practices in AI ethics. One major obstacle organisations face when attempting to operationalise AI Ethics is the lack of a well-defined material scope. Put differently, the question to which systems and processes AI ethics principles ought to apply remains unanswered. Of course, there exists no universally accepted definition of AI, and different systems pose different ethical (...) challenges. Nevertheless, pragmatic problem-solving demands that things should be sorted so that their grouping will promote successful actions for some specific end. In this article, we review and compare previous attempts to classify AI systems for the purpose of implementing AI governance in practice. We find that attempts to classify AI systems proposed in previous literature use one of three mental models: _the Switch_, i.e., a binary approach according to which systems either are or are not considered AI systems depending on their characteristics; _the Ladder_, i.e., a risk-based approach that classifies systems according to the ethical risks they pose; and _the Matrix_, i.e., a multi-dimensional classification of systems that take various aspects into account, such as context, input data, and decision-model. Each of these models for classifying AI systems comes with its own set of strengths and weaknesses. By conceptualising different ways of classifying AI systems into simple mental models, we hope to provide organisations that design, deploy, or regulate AI systems with the vocabulary needed to demarcate the material scope of their AI governance frameworks.

Realists about corporate agency, according to whom corporate agents may have aims above and beyond those of the individuals who make them up, think that individual agents may switch between participating in individual and corporate agency. My aim is, however, to argue that the inescapability of individual agency spells out a difficulty for this kind of switching – and, therefore, for realism about corporate agency. To do so, I develop Korsgaard’s notion of plight inescapability, which on my take suggests (...) that individual agents are continuously faced with fully exercising their individual agency (absent external limits at the time of its exercise). But then individual agents may not switch to acting as members of corporate agents if the aims of the corporation differ from their own, in the sense that they have different mental state tokens. But as it is possible to participate fully in the action of a corporate entity, this incompatibility between individual and corporate aims suggests that we ought to think of corporate agents as in some sense reducible to individual aims.

It has been proposed that processing sentential negation recruits the neural network of inhibitory control. In addition, inhibition mechanisms also play a role in switching languages for bilinguals. Since both processes may share inhibitory resources, the current study explored for the first time whether and how language-switching influences the processing of negation. To this end, two groups of Spanish-English bilinguals participated in an encoding-verification memory task. They read short stories involving the same two protagonists, referring to their activities (...) in four different scenarios in Spanish or English. Following each story, the participants received verification questions requiring “yes” or “no” responses depending on whether a given fact was correctly referred to one of the protagonists. Some of the verification questions were in the story’s original language and others in the alternate language. Results revealed that language-switching facilitated negative responses compared to affirmative responses, exclusively for questions switching from dominant language to non-dominant language. This effect might reflect that the domain-general mechanisms of inhibitory control are recruited at least partially for both language switch and negation process simultaneously, although this phenomenon is modulated by language dominance.

The use of more than one language in a literary text is called literary multilingualism. Ricci's trilogy presents this linguistic phenomenon as the author uses more than one linguistic code in the same text: English, Italian, and dialect. This work describes how code-switching becomes an important device of mimesis, representing not just a switching in language, but also a switch in culture, style, and in voice. This study demonstrates how Ricci exploited his linguistic richness on a literary level (...) creating novels that present the Italian world in a realistic way, but at the same time making use of linguistic varieties as literary device.

An explicitly frame related interpretation of a very general more for less result is used to establish a correspondingly general class of frame related switching results. These are used in turn to show how preference reversals of kinds found by Allais and others may not only be essentially non-paradoxical in character, but can be expected to be frequently observed, even under conditions of certainty and of complete information.

This study investigates switching costs in landmark-based wayfinding using olfactory and visual landmark information. It has already been demonstrated that there seem to be no switching costs, in terms of correct route decisions, when switching between acoustically and visually presented landmarks. Olfaction, on the other hand, is not extensively focused on in landmark-based wayfinding thus far, especially with respect to modality switching. The goal of this work is to empirically test and compare visual and olfactory landmark (...) information with regard to their suitability for wayfinding including a modality switch. To investigate this, an experiment within a virtual environment was conducted in which participants were walked along a virtual route of 12 intersections. At each intersection, landmark information together with directional information was presented, which was to be memorized and recalled in the following phase, either in the same or in the other modality. The results of the study show that, in contrast to the no-switching costs between auditory and visual landmarks in previous studies, switching costs occur when switching modality from visual to olfactory and vice versa. This is indicated by both longer decision times and fewer correct decisions. This means that a modality switch involving olfactory landmark information is possible but could lead to poorer performance. Therefore, olfaction may still be valuable for landmark-based-wayfinding. We argue that the poorer performance in the switching-condition is possibly due to higher cognitive load and the separate initial processing of odors and images in different cognitive systems.

This commentary identifies two problems concerning the switch mechanism: The model explains too few instances of switching, and the switching mechanism itself seems fallible. The improvements we suggest are to clarify the nature of the competing intuitions as the initial intuition and its negation or alternative ways to solve the problem, and to incorporate cognitive disfluency into the switching mechanism.

The contributions to this volume are concerned with questions of form, function, and genesis of canonical switch-reference systems.

Exploration of immune systems in prokaryotes, such as restriction‐modification or CRISPR‐Cas, shows that both innate and adaptive systems possess programmed cell death (PCD) potential. The key outstanding question is how the immune systems sense and “predict” infection outcomes to “decide” whether to fight the pathogen or induce PCD. There is a striking parallel between this life‐or‐death decision faced by the cell and the decision by temperate viruses to protect or kill their hosts, epitomized by the lysis‐lysogeny switch of bacteriophage Lambda. (...) Immune systems and temperate phages sense the same molecular inputs, primarily, DNA damage, that determine whether the cell lives or dies. Because temperate (pro)phages are themselves components of prokaryotic genomes, their shared “interests” with the hosts result in coregulation of the lysis‐lysogeny switch and immune systems that jointly provide the cell with the decision machinery to probe and predict infection outcomes, answering the life‐or‐death question.

Poly(ADP‐ribosyl)ation is a post‐translational modification occurring in the nucleus. The most abundant and best‐characterized enzyme catalyzing this reaction, poly(ADP‐ribose) polymerase 1 (PARP1), participates in fundamental nuclear events. The enzyme functions as molecular “nick sensor”. It binds with high affinity to DNA single‐strand breaks resulting in the initiation of its catalytic activity. Activated PARP1 promotes base excision repair. In addition, PARP1 modifies several transcription factors and thereby precludes their binding to DNA. We propose that a major function of PARP1 includes the (...) silencing of transcription preventing expression of damaged genes. Concomitant stimulation of DNA repair suggests that PARP1 acts as a switch between transcription and DNA repair. Another PARP‐type enzyme, tankyrase, is involved in the regulation of telomere elongation. Tankyrase modifies a telomere‐associated protein and thereby prevents it masking telomeric repeats providing access of telomerase for telomere elongation. Therefore, poly(ADP‐ribosyl)ation reactions may act as molecular switches in DNA metabolism. BioEssays 23:543–548, 2001. © 2001 John Wiley & Sons, Inc. (shrink)

Half a century into the digital era, the profound impact of information technology on intellectual and cultural life is universally acknowledged but still poorly understood. The sheer complexity of the technology coupled with the rapid pace of change makes it increasingly difficult to establish common ground and to promote thoughtful discussion. Responding to this challenge, _Switching Codes _brings together leading American and European scholars, scientists, and artists—including Charles Bernstein, Ian Foster, Bruno Latour, Alan Liu, and Richard Powers—to consider how the (...) precipitous growth of digital information and its associated technologies are transforming the ways we think and act. Employing a wide range of forms, including essay, dialogue, short fiction, and game design, this book aims to model and foster discussion between IT specialists, who typically have scant training in the humanities or traditional arts, and scholars and artists, who often understand little about the technologies that are so radically transforming their fields. _Switching Codes_ will be an indispensable volume for anyone seeking to understand the impact of digital technology on contemporary culture, including scientists, educators, policymakers, and artists, alike.

Shortcuts to goals are rewarded by faster attainment and punished by more frequent failure, so selection of the various kinds – heuristics, cached sequences (habits or macros), gut instincts – depends on reward history just like other kinds of choice. The speeds of shortcuts lie on continua along with speeds of deliberation, and these continua have no obvious separation points.

Culture-as-situated cognition theory provides insight into the system 1 monitoring algorithm. Culture provides people with an organizing framework, facilitating predictions, focusing attention, and providing experiential signals of certainty and uncertainty as system 1 inputs. When culture-based signals convey that something is amiss, system 2 reasoning is triggered and engaged when resources allow; otherwise, system 1 reasoning dominates.

The relationship between bilingual language control and executive control is debated. The present study investigated the effect of short‐term language switching in a comprehension task on executive control performance in unbalanced bilinguals. Participants were required to perform a context task and an executive control task (i.e., flanker task) in sequence. A picture‐word matching task created different language contexts in Experiment 1 (i.e., L1, L2, and dual‐language contexts). By modifying the color‐shape switching task, we created different contexts that do (...) not involve language processing in Experiment 2 (i.e., color, shape, and dual context). Experiment 1 showed overall faster responses (in both congruent and incongruent trials) in the flanker task after a language switching context than after single (L1 or L2) contexts. This suggests that the language switching in a comprehension task affected general monitoring performance. By contrast, the nonlinguistic contexts in Experiment 2 did not affect flanker performance. This provides further evidence for the crucial role of language processing during switching to elicit short‐term adaptions on domain‐general conflict monitoring. Overall, our findings add to the previous studies by showing cross‐talk between bilingual language control and domain‐general conflict monitoring when language switching occurs in a comprehension task.

Studies on event-related potentials (ERP) in code-switching (CS) have concentrated on single-word insertions, usually nouns. However, CS ranges from inserting single words into the main language of discourse to alternating languages for larger segments of a discourse, and can occur at various syntactic positions and with various word classes. This ERP study examined native speakers of Russian who had learned German as a second language; they were asked to listen to sentences with CS from their second language, German, to (...) their first language, Russian. CS included either a whole prepositional phrase or only the lexical head noun of a prepositional phrase. CS at nouns resulted in a late positive complex (LPC), whereas CS at prepositions resulted in a broad early negativity, which was followed by an anterior negativity with a posterior positivity. Only in the last time window (800–1000 ms) did CS at prepositions result in a broad positivity similar to CS at nouns. The differences between both types of CS indicate that they relate to different psycholinguistic processes. (shrink)

In his Perception and Reason, Bill Brewer argues that one can only have empirical beliefs if one’s perceptual experiences serve as reasons for such beliefs. His argument for this idea relies on a premise according to which in order for the relations with perceptual experience to determine the contents of empirical beliefs, these relations must be reason-giving. He offers an argument for this premise, the so-called Switching Argument. In this paper, I show that the Switching Argument does not (...) work, in which case we have no reason to accept the premise the argument is supposed to establish, and hence no reason to accept Brewer’s argument in favour of the idea that one can only have empirical beliefs if one’s perceptual experiences serve as reasons for such beliefs.
