Initially Einstein, Podolsky, and Rosen (EPR) and later Bell shed light on the non-local properties exhibited by subsystems in quantum mechanics. Separately, Kochen and Specker analyzed sets of measurements of compatible observables and found that a consistent coexistence of these results is impossible, i.e., quantum indefiniteness of measurement results. As a consequence, quantum contextuality, a more general concept compared to non-locality, leads to striking phenomena predicted by quantum theory. Here, we report neutron interferometric experiments which investigate entangled states in a (...) single-particle system: entanglement is, in this case, achieved not between particles, but between degrees of freedom i.e., between spin, path, and energy degrees of freedom. Appropriate combinations of the spin analysis and the position of the phase shifter in the interferometer allow an experimental verification of the violation of a Bell-like inequality. In addition, state tomography, tomographic analysis of the density matrix of a quantum system, and Kochen-Specker-like phenomena are presented to characterize neutrons’ entangled states and their peculiarity. Furthermore, a coherent energy manipulation scheme is accomplished with a radio-frequency (RF) spin-flipper. This scheme allows the (total) energy degree of freedom to be entangled: the remarkable behavior of a triply entangled GHZ-like state is demonstrated. (shrink)

Intelligent communication processing in English aims to obtain effective information from unstructured text data using various text processing techniques. Text vector representation and text similarity calculation are important fundamental tasks in the whole field of natural language processing. In response to the shortcomings of existing sentence vector representation models and the singularity of text similarity algorithms, improved models and algorithms are proposed based on a thorough study of related domain technologies. This paper presents an in-depth and comprehensive study of text (...) vectorization representation and text similarity calculation algorithms in the field of natural language processing. The existing text vectorized representation models and text similarity computation algorithms are described, and their shortcomings are summarized to provide a basis for the background and significance of this paper, as well as to provide ideas for improvement directions. It is experimentally verified that the sentence vector model proposed in this paper achieves higher accuracy than the SIF sentence vector model for text classification tasks. In the task of text similarity computation, it achieves better results in three evaluation metrics: accuracy, recall, and F1 value. The algorithm also improves the computational efficiency of the model to a certain extent by removing feature words with low feature contribution. The algorithm first improves the deficiencies of the traditional word-shift distance algorithm by defining multifeature fusion weights and realizes a text similarity calculation algorithm based on multifeature weighted fusion with better similarity calculation results. Then, a linear weighting model is constructed to further combine the similarity calculation results of the hierarchical pooled IIG-SIF sentence vectors to realize the multimodel fusion text similarity calculation algorithm.

This study examines the impact of board gender diversity on financial misconduct. The findings suggest firms with gender-diverse boards commit fewer financial reporting mistakes and engage in less fraud. The findings hold after accounting for the potentially endogenous nature of board demographic characteristics via instrumental variable approach. Furthermore, the findings are consistent in pre- and post-regulation periods and hold for firms with good and bad governance. The findings do not seem driven by differences in effort or quality, in terms of (...) independence and expertise, of female and male directors. The benefit derived from increasing the number of female directors on corporate boards seems to diminish at higher levels of gender diversity, indicating that impact of gender diversity on decreasing the likelihood of financial misconduct may be a result of a change to board group dynamics.

Which non-human animals are phenomenally conscious? In this paper I argue that the distribution of phenomenal consciousness in the animal world is ultimately an unsolvable issue, because of an underlying problem inherent in the field: what I call the Kinda Hard Problem. The Kinda Hard Problem arises because the grounds on which we base our consciousness attributions to humans third-personally are either unavailable or ambiguous once we move to the animal case. Its nature is that of an epistemic problem: we (...) cannot collect enough evidential grounds to justify attributions of phenomenal consciousness (and attributions of its lack) to non-human animals. Thus, it is impossible to ground rational belief one way or another regarding animal consciousness. This paper presents the problem and explains how it differs from other problems of consciousness.

In recent years, autonomous systems have become an important research area and application domain, with a significant impact on modern society. Such systems are characterized by different levels of autonomy and complex communication infrastructures that allow for collective decision-making strategies. There exist several publications that tackle ethical aspects in such systems, but mostly from the perspective of a single agent. In this paper we go one step further and discuss these ethical challenges from the perspective of an aggregate of autonomous (...) systems capable of collective decision-making. In particular, in this paper, we propose the Caesar approach through which we model the collective ethical decision-making process of a group of actors—agents and humans, as well as define the building blocks for the agents participating in such a process, namely Caesar agents. Factors such as trust, security, safety, and privacy, which affect the degree to which a collective decision is ethical, are explicitly captured in Caesar. Finally, we argue that modeling the collective decision-making in Caesar provides support for accountability. (shrink)

This study introduces visual cognition into Lithium-ion battery capacity estimation. The proposed method consists of four steps. First, the acquired charging current or discharge voltage data in each cycle are arranged to form a two-dimensional image. Second, the generated image is decomposed into multiple spatial-frequency channels with a set of orientation subbands by using non-subsampled contourlet transform. NSCT imitates the multichannel characteristic of the human visual system that provides multiresolution, localization, directionality, and shift invariance. Third, several time-domain indicators of the (...) NSCT coefficients are extracted to form an initial high-dimensional feature vector. Similarly, inspired by the HVS manifold sensing characteristic, the Laplacian eigenmap manifold learning method, which is considered to reveal the evolutionary law of battery performance degradation within a low-dimensional intrinsic manifold, is used to further obtain a low-dimensional feature vector. Finally, battery capacity degradation is estimated using the geodesic distance on the manifold between the initial and the most recent features. Verification experiments were conducted using data obtained under different operating and aging conditions. Results suggest that the proposed visual cognition approach provides a highly accurate means of estimating battery capacity and thus offers a promising method derived from the emerging field of cognitive computing.

The main thesis of Heyes' book is that all of the domain-specific learning mechanisms that make the human mind so different from the minds of other animals are culturally created and culturally acquired gadgets. The only innate differences are some motivational tweaks, enhanced capacities for associative learning, and enhanced executive function abilities. But Heyes' argument depends on contrasting cognitive gadgets with cognitive instincts, which are said to be innately specified. This ignores what has for some years been the mainstream nativist/anti-empiricist (...) view, which commits only to partially specified learning systems that become elaborated and built through domain-specific learning.

Nitric oxide (NO) is involved in synaptic long-term potentiation (LTP) by multiple signaling pathways. Here, we show that LTP of synaptic transmission can be explained as a feature of signal transduction—bistable behavior in a chain of biochemical reactions with positive feedback, formed by diffusion of NO to the presynaptic site and facilitating the release of glutamate (Glu). The dynamics of Glu, calcium (Ca2+) and NO is described by a system of nonlinear reaction–diffusion equations with modified Michaelis–Menten (MM) kinetics. Numerical investigation (...) reveals that the chain of biochemical reactions analyzed can exhibit a bistable behavior under physiological conditions when production of Glu is described by MM kinetics and decay of NO is modeled by means of two enzymatic pathways with different kinetic properties. Our finding extends understanding of the role of NO in LTP: a short high-intensity stimulus is “memorized” as a long-lasting elevation of NO concentration. The conclusions obtained by analysis of the chain of biochemical reactions describing LTP can be generalized to other chains of interactions or for creating the logical elements for biological computers.

This article analyses the gendered nature of teachers’ views on schools and security. Current research on security emphasizes masculinity and the absence of femininity in relation to the security field – traditionally dominated by the military and emergency rescue services. However, there is a lack of knowledge on the areas of society that are new to the security field. Schools, pupils and teachers are gendered in many ways. What happens when security is added to this nexus? Existing, limited research suggests (...) that this relationship may be both complicated and gendered. A qualitative content analysis is conducted based on interviews with teachers and principals from two municipalities in Sweden. It shows that teachers hold gendered views of their roles as security actors; of pupils in relation to security, as subjects of risks and sources of threats; and of external security threats. Men are embodied as positive or negative actors, whereas women are embodied mostly as powerless actors. Teachers give voice to a discourse focused on everyday insecurities. This is important, as the role of teachers as promoters of democratic citizens risks becoming undermined, and individual perspectives of security risk becoming replaced by national perspectives.

In verschiedenen Beiträgen dieses Bandes wird soziologisch und ästhetisch, kunst- und literaturwissenschaftlich erörtert, wie aus ästhetischen Erfahrungen Widerstandskraft gegen Zerstörung und Selbstzerstörung entwickelt wird. Es wird gezeigt, dass Kunst und Gesellschaft nicht ohne ästhetischen Widerstand zu machen sind. Dieser äußert sich nicht nur in der Produktion und in der Rezeption von Kunst, sondern auch in vielfältigen Praxen der Lebenswelt. Welche Rolle spielt ästhetische Erfahrung heute für die Fragen des guten Lebens und wie ist Ästhetik mit dem Leben selbst verbunden? Wie (...) kann das Verhältnis von Ethik und Ästhetik heute gesellschaftlich und politisch gedacht und vermittelt werden? Und vor allem: Wie kann der Destruktionsdynamik als Sucht und Sog gesellschaftlicher Selbstzerstörung durch ästhetischen Widerstand wirksam Einhalt geboten werden? (shrink)

In this paper, the ethics of otherness of Emmanuel Levinas, for whom the nudity of the Face (visage) is never a matter of style but moral conscience, encounters the theory of (cultural) dialogical action, foundation for Paulo Freire’s pedagogy of the oppressed and its denunciation-enunciation of dehumanization and oppression. For both authors, violence gets the meaning of possession, way throughout an entity, although existing, is partially negated. Such partiality, when negating the independence of the entity, states oppression, as it negates (...) the oppressed vocation to be more. Oppression kills life. Whereas, it is through the conscience of such condition of beingfor-other that the proper possibility of humanity can be thought, because the relation to the other or to the collective is our relation, irreducible to understanding. To recognize such subversion, therefore, is to recognize that as the oppressed free themselves, they avoid to get back to an oppressive regime. In doing so, they free their prior oppressors, they inaugurate love. Is it not to assume, in essence, that ethics is a construction of sense of life since the encounter with the Other? KEY WORDS – Humanism. Freedom. Ethics of otherness. Pedagogy of the oppressed. Social transformation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Cartographic Memory: Social Movement Activism and the Production of Space by Juan HerreraAída R. GuhlincozziCartographic Memory: Social Movement Activism and the Production of Spaceby juan herrera Durham, N.C.: Duke University Press, 2022Juan Herrera’s historical recounting of Latino activism in Fruitvale, California, in Cartographic Memory: Social Movement Activism and the Production of Space is stellar. In fact, the case focused on by Herrera as an example of activism producing (...) space and creating change in the name of social justice is not the only top-quality contribution to Latinx geographies to be found in this book. Herrera’s conceptualization of “cartographic memory” builds on the intertwining of Latinx writers and historians with traditional spatial thought from the history of geography. His definition of “cartographic memory” as a “political remaking of urban geography and therefore a selective mapping” adds to the broader oeuvre of activism and space coming out in recent years (14).The geographic location for Cartographic Memory comes from the author’s long history of working in and around Fruitvale as both a volunteer and community member. As a new resident of the Oakland area, Herrera mistakenly navigated himself to Fruitvale, where he found the elements of the place clearly speaking to a cultural aesthetic of Latin-idad. Intrigued, Herrera began volunteering in the area, and learned more of the long activist history of the space. That activist history, Herrera argues, has long been under-studied, or even forgotten, in Chicano activist history, and merits recognition. Herrera’s efforts with [End Page 139] this book go a long way to gathering together that spatial history and reconstructing it for the reader through interviews and oral histories with numerous activists, extensive archival research, and ethnography focusing on the 1960s and 1970s Mexican-American activist mobilization in support of the Chicano movement.The power of the focus on Fruitvale must be recognized, as Herrera also makes space for intently peeling apart the layers of nonprofit funding, social movements, and community-building and support. The chapter, “Revolution Interrupted,” is about the funding situation of the Unity Council in Fruitvale and how the funding structure was constructed over time in the context of the political and economic opportunities of the 1960s. It speaks to how this had a profound effect on the organizers and community given the shift from grassroots to institutional funding. This chapter opens the book with a focus on the national scope of funding opportunities for organizations in the 1960s that focused on race and ethnicity. Through this lens are explored the effects of local political actions—such as the 1969 speech by San Antonio-based Mexican American Youth Organization (MAYO) leader Jose Angel Gutierrez—on funding at the federal level. Because of the perceived militancy of these remarks, the U.S. Congress became concerned, and eventually passed the 1969 Tax Reform bill, limiting the types of projects that could be funded philanthropically. This type of multi-scale understanding of Fruitvale activism is threaded throughout the entire book, from chapter 1, “Making Place,” in which Herrera summarizes activist perspectives on Fruitvale as emphasizing “not only how the neighborhood itself [produced] a geography of activism but also how it was interconnected to other places of struggle throughout the United States” (emphasis in original; 33).Herrera also navigates the interactions of race, ethnicity, and space, tracing how coalitions, influences on political efforts, and collaboration took place throughout Fruitvale and Oakland during this period. His second chapter, “The Other Minority,” identifies where Black Panther Party-related work occurred; the marketization that began to occur of a non-threatening, non-Black “Latino” identity; the effect that this had on activist efforts; and more. Importantly, in this chapter Herrera’s interviews reveal that part of the interest in these coalitions came from the clear organizational success Black activists had achieved in their [End Page 140] work, leading Mexican American activists in Oakland to pursue similar efforts. One interviewee, Herman Gallegos, a prominent activist at the time, spoke of recalling an event where Black men would gather monthly to focus on leadership. Thinking highly of them, he says that he recognized them as future “mayors, judges... [but] kept thinking... (shrink)

Research documents that many chronic non-malignant pain patients experience existential, spiritual and religious needs; however, research knowledge is missing on if and how physicians approach these needs. We conducted a systematic review to explore the extent to which physicians address these needs in their communication with chronic non-malignant pain patients and to explore the facilitators and challenges of this communication. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, searching Embase, Medline, Scopus and PsycINFO. The quality of (...) the included articles was assessed based on design-specific screening tools. We included four of 2337 screened articles and found the quality to be good. Physicians’ communication about existential, spiritual and religious needs was given low priority and depended on the patients’ own initiative, except when clinicians were interested in holistic care. Patient dissatisfaction with the physician’s attention to these needs was related to higher pain and depression. Physicians’ challenges for addressing these needs were their tendency to prioritize physiological aspects and close further elaboration of existential needs when addressed by the patients. The main facilitator was the individual physician’s willingness to listen with openness and empathy to the patients’ existential concerns. A tentative conclusion is that physicians rarely meet the existential, spiritual and religious needs of their chronic non-malignant pain patients. This might be due to higher priority of physical aspects, lack of time and a lack of knowledge about the importance of and training in the ability to address these needs. Further research is needed on physicians’ communication about existential, spiritual and religious needs and on their training in here. (shrink)

ABSTRACT In volume two of his work Democracy in America, Alexis de Tocqueville argued that religion could guarantee individual liberties against the tyranny of the majority. However, in volume one of this work, Tocqueville presented a conventional ‘civil religion’ as a phenomenon that was identical to or subsumed by American social mores or opinions. Thus, the following questions are raised: How can such a religion represent a brake on potential tyranny? How can genuine religion be distinguished from common opinion? Consequently, (...) understanding Tocqueville’s approach to religion remains a major problem. This article demonstrates that in the second volume of Democracy in America, Tocqueville suggested a different type of civil religion, one that has a transcendent authority that distinguishes it from public opinion but that, nevertheless, facilitates intellectual liberty. It also shows how Tocqueville resolved the dilemmas of authority and liberty in the civil religion, by focusing on, with his observations of American Christianity, his reading of Blaise Pascal’s works regarding religious authority and human reason, in which Pascal exhorted human beings to willingly recognise the limits of reason.

Megaprojects are implemented by different organisations, such as owners, consultants, and contractors. Gradually, these organisations and their connections can form business networks that influence both the market position of individual organisations and project performance. Previous research on large-scale projects mainly focused on static and homogeneous networks that were constructed by one individual project and/or carried out over one-off collaboration. However, this neglected the consideration of project network diversity, as well as repetitive, dynamic, cross-project coopetition relationship and long-term business networks formed (...) by key actors. Here, we chose Chinese skyscrapers over 300 meters that were built from 1996 to 2015 as typical megaproject cases and analysed the formation and evolution of megaproject business networks from the perspective of interorganisational coopetition. We identified the key actors involved and empirically studied their dynamic network positions over time. The main contributions of this study are threefold. First, we found that past collaboration experience has direct and dynamic impacts on the formation of megaproject business networks. Second, we identified key actors in the interorganisational business network and unveiled their dynamic positions with clear patterns. Third, we highlighted the temporal-spatial effect on the formation and development of business networks, alongside developments in the megaproject market. The findings of this study also provide practical applications for owners to choose collaboration partners and to build high-performance teams and for suppliers to enter and sustain the business in the megaprojects networks.

A partir de las experiencias vitales del Colectivo Les Pites se pueden observar una serie de estructuras y dinámicas normativas dentro del baile tradicional asturiano derivadas del sistema cisheteropatriarcal en el que se inscribe. Existe un discurso de normatividad de género imbricado en esta manifestación cultural a lo largo de su historia, comenzando con referencias en la obra de Jovellanos (siglo XVIII). Este discurso hegemónico continua durante la época franquista con Coros y Danzas de la Sección Femenina y el uso (...) del folclore al servicio de la transmisión ideológica del Régimen. Con el paso a la democracia, este discurso normativo adquiere otras formas de mantenerse imbuido en el baile tradicional, evidenciando la fragilidad de la cultura de la Transición que más tarde será cuestionada a partir del año 2008. La necesidad de encontrar nuevos caminos y posibilidades, además del hecho de reconocer la agencia de las personas y la disidencia inherentemente ligada a la norma, conduce a Les Pites a ofrecer una serie de adaptaciones metodológicas en sus talleres de baile tradicuir para poder utilizar el baile tradicional asturiano como un vehículo de comunicación e interacción que forme parte de los diversos espacios colectivos de ocio propios de la actual sociedad asturiana.

To understand Plato’s Republic as a whole, we must know his notion of injustice as well as that of justice, since he makes a comparison between the life of justice and the life of injustice. Prior to his detailed analyses of injustice in Books IV, VIII, and IX, Plato discusses injustice philosophically even in Book I. In this paper I deal with 351b-352b where Plato clarifies the function of injustice by appeal to the analogy between city and individual. According to (...) Plato, injustice in the city causes hatred in each citizen, which results in the civil war and fighting among them, leading to the destruction of the city. Analogously, Plato discusses the function of injustice in the individual, showing that hatred is the most fundamental function of injustice. Plato’s analogy, though, includes two remarkablediscrepancies between city and individual. First, justice in the individual causes a conflict among beliefs and desires, which makes him incapable of doing anything, while social injustice still allows the city lacking its unity to do something. Second, hatred or hostility social injustice engender in each citizen is directed toward others, whereas injustice in the individual produces self-disgust of the whole soul, functioning as the destructive principle of the soul. This is howthis argument serves to foreshadow Plato’s analyses of injustice in the remainder of the Republic. (shrink)

Anhedonia is the diminished motivation and sensitivity to pleasurable stimuli. It has been reported to be more prevalent in patients with chronic pain as compared to healthy controls. Endometriosis is a chronic inflammatory systemic disease with a significant psychosocial impact that compromises wellbeing and the day-to-day life of patients. Women with endometriosis show significant psychological distress, even more pervasive when chronic pelvic pain is present. In the current review we will discuss the role of anhedonia in endometriotic chronic pelvic pain. (...)

In recent years, social networks have made significant progress and the number of people who use them to communicate is increasing day by day. The vast amount of information available on social networks has led to the importance of using friend recommender systems to discover knowledge about future communications. It is challenging to choose the best machine learning approach to address the recommender system issue since there are several strategies with various benefits and drawbacks. In light of this, a solution (...) based on the stacking approach was put out in this study to provide a buddy recommendation system in social networks. Additionally, a decrease in system performance was caused by the large amount of information that was accessible and the inefficiency of some functions. To solve this problem, a particle swarm optimization algorithm to select the most efficient features was used in our proposed method. To learn the model in the objective function of the particle swarm algorithm, a hybrid system based on stacking is proposed. In this method, two random forests and Extreme Gradient Boosting had been used as the base classifiers. The results obtained from these base classifiers were used in the logistic regression algorithm, which has been applied sequentially. The suggested approach was able to effectively address this issue by combining the advantages of the applied strategies. The results of implementation and evaluation of the proposed system show the appropriate efficiency of this method compared with other studied techniques. (shrink)

Transgender women experience serious psychiatric problems and high suicide rates. According to the interpersonal theory of suicide, thwarted belongingness and perceived burdensomeness play major roles in suicidality and can be measured by the Interpersonal Needs Questionnaire. However, no study has validated the use of the INQ in TGW. This study aimed to examine the psychometric properties of the INQ among TGW. We recruited 198 TGW from Shenyang, China, using snowball sampling. The construct validity of the INQ was assessed through factor (...) analysis, and convergent and divergent validity were examined through a structural equation model with other psychosocial factors. The construct validation analysis supported a three-factor model with satisfactory fit indices: χ2/df = 1.54, RMSEA = 0.052, CFI = 0.931, TLI = 0.916, SRMR = 0.053. The thwarted belongingness was significantly associated with self-esteem and social support, and the social exclusion was significantly associated with loneliness, depression, entrapment, and defeat, suggesting satisfactory convergent and divergent validity for the three-factor model. The present findings indicate that for TGW, high social exclusion is important in assessing perceived interpersonal needs, while the notable deviation from previous two-factor model warrants further study.

Backgrounds: Transcranial direct current stimulation is a non-invasive brain stimulation technique for the treatment of several psychiatric disorders, e.g., mood disorders and schizophrenia. Therapeutic effects of tDCS are suggested to be produced by bi-directional changes in cortical activities, i.e., increased/decreased cortical excitability via anodal/cathodal stimulation. Although tDCS provides a promising approach for the treatment of psychiatric disorders, its neurobiological mechanisms remain to be explored.Objectives: To review recent findings from neurophysiological, chemical, and brain-network studies, and consider how tDCS ameliorates psychiatric conditions.Findings: (...) Enhancement of excitatory synaptic transmissions through anodal tDCS stimulation is likely to facilitate glutamate transmission and suppress gamma-aminobutyric acid transmission in the cortex. On the other hand, it positively or negatively modulates the activities of dopamine, serotonin, and acetylcholine transmissions in the central nervous system. These neural events by tDCS may change the balance between excitatory and inhibitory inputs. Specifically, multi-session tDCS is thought to promote/regulate information processing efficiency in the cerebral cortical circuit, which induces long-term potentiation by synthesizing various proteins.Conclusions: This review will help understand putative mechanisms underlying the clinical benefits of tDCS from the perspective of neurotransmitters, network dynamics, intracellular events, and related modalities of the brain function.

Intelligence, genius and mental ability were a cluster of traits that received much attention in eugenics discourse. Intelligence was regarded as one of the good qualities superior men possessed, in turn beneficial for society as a whole. On the other hand, the socially problematic or unproductive were identified as being of inferior mental quality: “feeble-minded”. By and large, eugenicists thought that (1) intelligence was a unitary psychological trait that could be measured, being quantified as an intelligence quotient (IQ); (2) intelligence (...) was paired with educational achievement, reputation, and economic success; (3) a certain degree of intelligence was necessary to act morally and to foresee the consequences of one’s actions. Despite the prominent role of intelligence in the history of eugenics, there is considerable lack of clarity in what this general mental ability was considered to be. (shrink)

Cytoskeletal organization in embryonic skeletal muscle cells has been examined by transmission electron microscopy; the technique involves preparation using the platinum replication method of freezedried samples, with and without cryofracture. The cytoskeletons in developing muscle cells appear to play a role in preserving cell shape as well as in anchoring myofibrils to cell membrane.
