“Kama muta” or ‘being moved by love’: a bootstrapping approach to the ontology and epistemology of an emotion

The emotion that people may label being moved, touched, having a heart-warming experience, rapture, or tender feelings evoked by cuteness has rarely been studied and is incompletely conceptualized. Yet it is pervasive across history, cultures, and contexts, shaping the most fundamental relationships that make up society. It is positive and can be a peak or ecstatic experience. Because no vernacular words consistently or accurately delineate this emotion, we call it kama muta. We posit that it is evoked when communal sharing relationships suddenly intensify. Using ethnological, historical, linguistic, interview, participant observation, survey, diary, and experimental methods, we have confirmed that when people report feeling this emotion they perceive that a relationship has become closer, and they tend to have a warm feeling in the chest, shed tears, and/or get goosebumps. We posit that the disposition to kama muta is an evolved universal, but that it is always culturally shaped and oriented; it must be culturally informed in order to adaptively motivate people to devote and commit themselves to new opportunities for locally propitious communal sharing relationships. Moreover, a great many cultural practices, institutions, roles, narratives, arts and artifacts are specifically adapted to evoke kama muta: that is their function.info:eu-repo/semantics/acceptedVersio

The sudden devotion emotion: kama muta and the cultural practices whose function is to evoke it

When communal sharing relationships (CSRs) suddenly intensify, people experience an emotion that English speakers may label, depending on context, “moved,” “touched,” “heart-warming,” “nostalgia,” “patriotism,” or “rapture” (although sometimes people use each of these terms for other emotions). We call the emotion kama muta (Sanskrit, “moved by love”). Kama muta evokes adaptive motives to devote and commit to the CSRs that are fundamental to social life. It occurs in diverse contexts and appears to be pervasive across cultures and throughout history, while people experience it with reference to its cultural and contextual meanings. Cultures have evolved diverse practices, institutions, roles, narratives, arts, and artifacts whose core function is to evoke kama muta. Kama muta mediates much of human sociality.info:eu-repo/semantics/acceptedVersio

NMDAR-Activated PP1 Dephosphorylates GluN2B to Modulate NMDAR Synaptic Content.

In mature neurons, postsynaptic N-methyl-D-aspartate receptors (NMDARs) are segregated into two populations, synaptic and extrasynaptic, which differ in localization, function, and associated intracellular cascades. These two pools are connected via lateral diffusion, and receptor exchange between them modulates synaptic NMDAR content. Here, we identify the phosphorylation of the PDZ-ligand of the GluN2B subunit of NMDARs (at S1480) as a critical determinant in dynamically controlling NMDAR synaptic content. We find that phosphorylation of GluN2B at S1480 maintains NMDARs at extrasynaptic membranes as part of a protein complex containing protein phosphatase 1 (PP1). Global activation of NMDARs leads to the activation of PP1, which mediates dephosphorylation of GluN2B at S1480 to promote an increase in synaptic NMDAR content. Thus, PP1-mediated dephosphorylation of the GluN2B PDZ-ligand modulates the synaptic expression of NMDARs in mature neurons in an activity-dependent manner, a process with profound consequences for synaptic and structural plasticity, metaplasticity, and synaptic neurotransmission

Human infants' learning of social structures: the case of dominance hierarchy

We tested 15-month-olds’ capacity to represent social-dominance hierarchies with more than two agents. Our results showed that infants found it harder to memorize dominance relations that were presented in an order that hindered the incremental formation of a single structure (Study 1). These results suggest that infants attempt to build structures incrementally, relation by relation, thereby simplifying the complex problem of recognizing a social structure. Infants also found circular dominance structures harder to process than linear dominance structures (Study 2). These expectations about the shape of structures may facilitate learning. Our results suggest that infants attempt to represent social structures composed of social relations. They indicate that human infants go beyond learning about individual social partners and their respective relations and form hypotheses about how social groups are organized

FABRICATION AND OPTIMIZATION OF NOVEL GLIPIZIDE SUSTAINED RELEASE MATRICES FOR SOLUBILITY AND DISSOLUTION ENHANCEMENT BY SOLID DISPERSION THROUGH HYDROPHILLIC CARRIERS

The present research work was to improve the dissolution rate of glipizide which belongs to BCS II drug by enhancing its aqueous solubility using different hydrophilic carriers like PEG 6000 and hydroxypropyl methylcellulose E15 (HPMC E15). The solid dispersion was embedded into the matrix of polymers to sustain the release pattern of drug. The various solid dispersion formulations were prepared by employing fusion method using different carriers. Further solid dispersion formulations were subjected to different in-vitro evaluation tests for solubility, drug content uniformity, drug-polymer interaction, DSC study and in-vitro drug release study. Tablets were prepared by direct compression method and evaluated for various physical parameters. A direct compression method using response surface methodology, followed by optimization of the evaluated parameters was employed to get the final optimized formulation. The results of drug content uniformity showed the uniform dispersion of glipizide in solid dispersion formulations. The DSC endothermic peak at 216.08°C due to glipizide was partially and completely disappeared in solid dispersion formulation indicating that drug was completely dispersed in formulations. In-vitro drug release showed 80.35% in 60 minutes for the best solid dispersion formulation S3 (ratio 1:3). Among all the formulations, F4 shows 92.87% better sustained release at the end of 12 hrs. The release co-efficient values ‘n’ (Ë‚0.5) indicated that the drug release followed fickian diffusion mechanism based on formulation factors. The stability studies were carried out according to ICH guideline and result found of selected formulation was stable.Keywords: Glipizide, Solid dispersion, Xanthan gum, MatricesÂ

Celebrity advocacy and public engagement: the divergent uses of celebrity

This article sounds a cautionary note about the instrumental use of celebrity advocacy to (re)engage audiences in public life. It begins by setting out the steps necessary to achieve public recognition of a social problem requiring a response. It then presents empirical evidence which suggests that those most interested in celebrity, while also paying attention to the main stories of the day, are also least likely to participate in any form of politics. However, this does not rule out the possibility of forging a link between celebrity and public engagement, raising questions about what would potentially sustain such an articulation. After discussing the broader cultural context of celebrity advocacy in which perceived authenticity functions valorised form of symbolic capital, the article outlines a phenomenological approach to understanding the uses audiences make of celebrity advocacy, using the example of a Ewan McGregor UNICEF appeal for illustration. It concludes that while media encounters with celebrities can underpin a viewer’s sense of self, this is as likely to lead to the rationalisation of inaction as a positive response to a charity appeal

Composite excitation of Josephson phase and spin waves in Josephson junctions with ferromagnetic insulator

Coupling of Josephson-phase and spin-waves is theoretically studied in a superconductor/ferromagnetic insulator/superconductor (S/FI/S) junction. Electromagnetic (EM) field inside the junction and the Josephson current coupled with spin-waves in FI are calculated by combining Maxwell and Landau-Lifshitz-Gilbert equations. In the S/FI/S junction, it is found that the current-voltage (I-V) characteristic shows two resonant peaks. Voltages at the resonant peaks are obtained as a function of the normal modes of EM field, which indicates a composite excitation of the EM field and spin-waves in the S/FI/S junction. We also examine another type of junction, in which a nonmagnetic insulator (I) is located at one of interfaces between S and FI. In such a S/I/FI/S junction, three resonant peaks appear in the I-V curve, since the Josephson-phase couples to the EM field in the I layer.Comment: 16 pages, 5 figure
