Recent accounts on the global workspace theory suggest that consciousness involves transient formations of functional connections in thalamo-cortico-cortical networks. The level of connectivity in these networks is argued to determine the state of consciousness. Emotions are suggested to play a role in shaping consciousness, but their involvement in the global workspace theory remains elusive. In the present study, the role of emotion in the neural workspace theory of consciousness was scrutinized by investigating, whether unconscious and conscious display of emotional compared (...) to neutral facial expressions would differentially modulate EEG coherence. EEG coherence was measured by means of computing an average EEG coherence value between the frontal, parietal, and midline scalp sites. Objective awareness checks evidenced that conscious identification of the masked facial expressions was precluded. Analyses revealed reductions in EEG coherence in the lower frequency range for the masked as compared to unmasked neutral facial expressions. Crucially, a decline in EEG coherence was not observed for the emotional facial expressions. In other words, the level of EEG coherence did apparently vary as a function of awareness, but not when emotion was involved. The current finding suggests that EEG coherence is modulated by unconscious emotional processes, which extends common views on the global workspace architecture of consciousness. (shrink)

Transcranial magnetic stimulation (TMS) is a method capable of transiently modulating neural excitability. Depending on the stimulation parameters information processing in the brain can be either enhanced or disrupted. This way the contribution of different brain areas involved in mental processes can be studied, allowing a functional decomposition of cognitive behavior both in the temporal and spatial domain, hence providing a functional resolution of brain/mind processes. The aim of the present paper is to argue that TMS with its ability to (...) draw causal inferences on function and its neural representations is a valuable neurophysiological tool for investigating the causal basis of neuronal functions and can provide substantive insight into the modern interdisciplinary and (anti)reductionist neurophilosophical debates concerning the relationships between brain functions and mental abilities. Thus, TMS can serve as a heuristic method for resolving causal issues in an arena where only correlative tools have traditionally been available. (shrink)

Behrendt & Young (B&Y) propose an explanation for schizophrenia in terms of a cortical default in the interaction between consciousness and cognition. However, schizophrenia more likely involves miscommunication between subcortical and cortical affective circuits in the brain, a default in the interaction between consciousness and emotion. The typical “affective” nature of hallucinations in schizophrenia provides compelling evidence for subcortical involvement.

Inadequate pain control, especially in older adults, remains a significant issue when caring for this population. Older adults, many of whom experience multiple acute and chronic conditions, are especially vulnerable to having their pain seriously underassessed and inadequately treated. Nurses have an ethical obligation to appropriately treat patients’ pain. To fulfill their ethical obligation to relieve pain in older patients, nurses often need to advocate on their behalf. This article provides an overview of the persistent problem of undertreated pain in (...) older adults and explores how nurses can meet this ethical duty through the application of Beauchamp and Childress’ three principles of beneficence.

Communication and interaction today happen in simply one mouse click away. Language and self-expression do not only develop as a recognized tool for oneself but is an avenue for others’ re-expression and identification. Through using Twitter, the elaboration of social interaction becomes easier and accessible. It becomes the primary method of doing things together and establishes a shared meaning that becomes the common ground of understanding by individuals and groups alike. The study aims to analyze the tweets of Kris Aquino, (...) known as the Philippines’ Queen of Multimedia using speech act categories of Searle and predict the meaning based on the speech acts committed. The study used content analysis for it represents systematic and objective means of describing and quantifying phenomena. The results showed that most tweets contained the ‘assertive’ label which refers to ‘those kinds of speech acts that state what the speaker believes to be the case or not’. Further, her influence as a public figure contributed to the forceful implication of realizing the speech act reflected by her readers. Since impression is reality and intention cannot be quantified, what the general audience perceives on a certain person serves to be the truth. Thus, misinterpretation develops due to poor judgment on the elucidation in the tweets of the posters, readers and vice-versa. Keywords - Sociolinguistics, speech act theory, Twitter, micro-blogging, SNS, qualitative, content analysis, Philippines. (shrink)

Temporal dynamics have been increasingly recognized as an important component of facial expressions. With the need for appropriate stimuli in research and application, a range of databases of dynamic facial stimuli has been developed. The present article reviews the existing corpora and describes the key dimensions and properties of the available sets. This includes a discussion of conceptual features in terms of thematic issues in dataset construction as well as practical features which are of applied interest to stimulus usage. To (...) identify the most influential sets, we further examine their citation rates and usage frequencies in existing studies. General limitations and implications for emotion research are noted and future directions for stimulus generation are outlined. (shrink)

Identity, Morality, and Threat offers a critical examination of the social psychological processes that generate outgroup devaluation and ingroup glorification as the source of conflict. Daniel Rothbart and Karyna Korostelina bring together essays analyzing the causal relationship between escalating violence and opposing images of the Self and Other.

Mazur & Booth's (1998) target article concerns basal and reciprocal relations between testosterone and dominance, and has its roots in Mazur's (1985; 1994) model of primate dominance-submissiveness interactions. Threats are exchanged in these interactions and a psychological stress-manipulation mechanism is suggested to operate, making sure that face-to-face dominance contests are usually resolved without aggression. In this commentary, a recent line of evidence from human research on the relation between testosterone, cortisol, and vigilant (dominant) and avoidant (submissive) responses to threatening “angry” (...) faces is discussed. Findings, to a certain extent, converge with Mazur & Booth's theorizing. However, the strongest relations have been found in subliminal exposure conditions, suggesting that biological instead of psychological mechanisms are involved. (shrink)

In this paper several problems are raised concerning Ian Barbour's four ways of interrelating science and religion—Conflict, Independence, Dialogue, and Integration—as put forward in such publications as his highly influential Religion in an Age of Science (1990) and widely adopted by other writers in this field. The authors argue that this taxonomy is not very useful or analytically helpful, especially to historians seeking to understand past engagements between science and religion.

I describe how relativistic field theory generalizes the paradigm property of material systems, the possession of mass, to the requirement that they have a mass–energy–momentum density tensor T µ associated with them. I argue that T µ does not represent an intrinsic property of matter. For it will become evident that the definition of T µ depends on the metric field g µ in a variety of ways. Accordingly, since g µ represents the geometry of spacetime itself, the properties of (...) mass, stress, energy, and momentum should not be seen as intrinsic properties of matter, but as relational properties that material systems have only in virtue of their relation to spacetime structure.

The contributors to this volume address global, regional, and local landscapes, cosmopolitan and indigenous cultures, and human and more-than-human ecology as they work to reveal place-specific tensional dynamics. This unusual book, which covers a wide-ranging array of topics, coheres into a work that will be a valuable reference for scholars of geography and the philosophy of place.

Research has found many positive benefits to person‐organization (PO) fit, for both individuals and the organization. However, PO misfit has received far less attention in the literature. In this article, we look specifically at PO misfit caused by the differing political values and beliefs of the CEO and employee. We argue that CEO activism influences employee perceptions of ideological misfit (IM), whereby differing political beliefs between employees and their activist CEO can impact workplace outcomes. We consider how peer group reactions, (...) ethical climate, external needs fulfillment, and moral identity serve as boundary conditions for perceptions of PO misfit and related organizational outcomes. We also examine antecedents of CEO activism. Drawing on academic literature from both the micro and macro perspectives of management research, we introduce a conceptual model and discuss implications for the firm and its employees. (shrink)

Progressive supranuclear palsy is a movement disorder with prominent tau neuropathology. Brain diseases with abnormal tau deposits are called tauopathies, the most common of which is Alzheimer's disease. Environmental causes of tauopathies include repetitive head trauma associated with some sports. To identify common genetic variation contributing to risk for tauopathies, we carried out a genome-wide association study of 1,114 individuals with PSP and 3,247 controls followed by a second stage in which we genotyped 1,051 cases and 3,560 controls for the (...) stage 1 SNPs that yielded P ≤ 10-3. We found significant previously unidentified signals associated with PSP risk at STX6, EIF2AK3 and MOBP. We confirmed two independent variants in MAPT affecting risk for PSP, one of which influences MAPT brain expression. The genes implicated encode proteins for vesicle-membrane fusion at the Golgi-endosomal interface, for the endoplasmic reticulum unfolded protein response and for a myelin structural component. © 2011 Nature America, Inc.

Seeking to unlock the secrets of consciousness, neuroscientists have been studying neural correlates of sensory awareness, such as meaningless randomly moving dots. But in the natural world of species' survival, “raw feelings” mediate conscious adaptive responses. Merker connects the brainstem with vigilance, orientating, and emotional consciousness. However, depending on the brain's phylogenetic level, raw feeling takes particular forms. (Published Online May 1 2007).

The paper looks at the establishment of religion clause in the First Amendment to the US Constitution, and cases, e.g. Brown v. Gilmore, followed by Croft v. Perry and Sherman v. Koch, cases that relate to the concept of the “moment of silence” in educational institutions in which it was claimed that such events constitute a breach of the establishment clause. Courts have been inconsistent in their decision-making, which may indicate a lack of transparency not only in the interpretation of (...) the relevant phrase in the Constitution but also in the judicial interpretation of the “three-pronged test” with regard to “excessive entanglement” as laid out in Lemon v. Kurtzman of 1971. The paper discusses the “moment of silence” within the framework of a model of silence in which this type of silence would be labeled as either textual or situational silence.

We apply molecular code theory to a rule-based model of the human inner kinetochore and study how complex formation in general can give rise to molecular codes. We analyze 105 reaction networks generated from the rule-based inner kinetochore model in two variants: with and without dissociation of complexes. Interestingly, we found codes only when some but not all complexes are allowed to dissociate. We show that this is due to the fact that in the kinetochore model proteins can only bind (...) at kinetochores by attaching to already attached proteins and cannot form complexes in free solution. Using a generalized linear mixed model we study which centromere protein can take which role in a molecular code . By this, associations between CENPs and code roles are found. We observed that CenpA is a major risk factor while CenpQ is a major protection factor . Finally we show, using an abstract model of copolymer formation, that molecular codes can also be realized solely by the formation of stable complexes, which do not dissociate. For example, with particular dimers as context a molecular code mapping from two different monomers to two particular trimers can be realized just by non-selective complex formation. We conclude that the formation of protein complexes can be utilized by the cell to implement molecular codes. Living cells thus facilitate a subsystem allowing for an enormous flexibility in the realization of mappings, which can be used for specific regulatory processes, e.g. via the context of a mapping.
