Aesthetic Tradition and it’s few Theories

The basis of the aesthetic thought of Tamilians is their art and literature. Thus, Tolkappiyam is the best source for recording the tradition of Tamil aesthetic thought. Similarly, there are many references to the concept of beauty in Sangam literature. Although Tamil literature has recorded the term beauty related to literary creation and artwork, research on the term has not been carried out in the field of Tamil literary criticism. It is noteworthy that the first book written to explain Murugu or beauty in Tamil is Thiru. V. Kalyana Sundaranar's Murugan or Beauty. In this book, aesthetics are explained in some places with religious affiliation and in some places without religious affiliation. Given the definition of beauty, it is impossible to say with certainty that this is beauty. But there is a custom in the ancient Tamil society of dividing beauty into two categories: natural beauty and artificial beauty. Such beauty is formed according to the ideas that man has absorbed in the world. Similarly, the vision of beauty is formed according to the training of the senses. In particular, beauty differs according to his knowledge, experience, environment, and imagination. That is why the study of beauty is called aesthetics. Aesthetics is not only the study of beautiful things but also includes the study of things that are considered unattractive. Although everyone can get explanations for aesthetics from the perspective of approaching art in their own understanding, it is impossible to accept these alone as the final explanation of aesthetics. The reason is that aesthetics is different according to their understanding

Analysing the Changes in Physiological Response to Different Soundscape Scenarios

Noise pollution is one of the key environmental stressors leading to multiple health impacts for people and communities. Exposure to high noise levels may also be responsible for sudden emotional and physiological changes in humans. The experiment examines the change in Galvanic Skin Response (GSR) signals during exposure to pre-recorded soundscape scenarios. These scenarios were recorded in New Delhi, India and London, UK, using a binaural microphone set. The listening experiment was conducted in a laboratory, where 27 healthy individuals without any hearing impairment or any psychological issues participated. A total of 30 soundscape scenarios were presented to each participant in a randomised order. The continuous decomposition analysis is conducted to decompose that data into tonic and phasic components. The phasic component of the signal is used for the analysis. It is observed that skin conductance response increases with changes in eventfulness of the signal (P<0.05). The pleasantness of the signals has not shown a statistically significant relationship with the change in skin conductance response

Theoretical and Empirical Foundations of Divorce Education: Connecting Program Theory and Curricular Content

Many parent and family education programs lack a clearly articulated program theory that is solidly founded in the social science literature and used to guide rigorous evaluation. This article describes the program theory for Parents Forever, a divorce education program developed by the Minnesota Extension to serve divorcing parents. The Parents Forever program theory is theoretically based and empirically-informed. The program theory is based on three significant frameworks, which serve as the theoretical foundation for the program: human ecosystems, life course development, and family resilience. These theories are explored and discussed. Three primary change mechanisms relevant for divorcing families serve as the empirical foundation of the program. Parent-child and coparent relationships are commonly addressed in divorce education programs; however, the inclusion of parental self-care as the third mechanism to promote family resilience is a unique contribution of Parents Forever. Relevant concepts derived from the empirical literature related to these three mediators are presented. Connections between the curricular content and program theory (i.e., theoretical framework and three change mechanisms) are made explicit, and program theory is used to demonstrate the unique contribution that Parents Forever makes to the field of divorce education

Mesocorticolimbic monoamine correlates of methamphetamine sensitization and motivation.

Methamphetamine (MA) is a highly addictive psychomotor stimulant, with life-time prevalence rates of abuse ranging from 5-10% world-wide. Yet, a paucity of research exists regarding MA addiction vulnerability/resiliency and neurobiological mediators of the transition to addiction that might occur upon repeated low-dose MA exposure, more characteristic of early drug use. As stimulant-elicited neuroplasticity within dopamine neurons innervating the nucleus accumbens (NAC) and prefrontal cortex (PFC) is theorized as central for addiction-related behavioral anomalies, we used a multi-disciplinary research approach in mice to examine the interactions between sub-toxic MA dosing, motivation for MA and mesocorticolimbic monoamines. Biochemical studies of C57BL/6J (B6) mice revealed short- (1 day), as well as longer-term (21 days), changes in extracellular dopamine, DAT and/or D2 receptors during withdrawal from 10, once daily, 2 mg/kg MA injections. Follow-up biochemical studies conducted in mice selectively bred for high vs. low MA drinking (respectively, MAHDR vs. MALDR mice), provided novel support for anomalies in mesocorticolimbic dopamine as a correlate of genetic vulnerability to high MA intake. Finally, neuropharmacological targeting of NAC dopamine in MA-treated B6 mice demonstrated a bi-directional regulation of MA-induced place-conditioning. These results extend extant literature for MA neurotoxicity by demonstrating that even subchronic exposure to relatively low MA doses are sufficient to elicit relatively long-lasting changes in mesocorticolimbic dopamine and that drug-induced or idiopathic anomalies in mesocorticolimbic dopamine may underpin vulnerability/resiliency to MA addiction

Vibrational and stochastic resonances in driven nonlinear systems

Nonlinear systems are abundant in nature. Their dynamics have been extensively investigated due to their multidisciplinary applicability, ranging from all branches of physical and mathematical sciences to engineering as well as to life sciences and medicine. When driven by external forces, nonlinear systems can exhibit plethora of interesting and important properties - one of the most prominent being resonance. In the presence of a second, higher frequency, driving force, whether stochastic or deterministic/periodic, a resonance phenomenon arises that can generally be termed stochastic resonance or vibrational resonance. Operating a system in or out of resonance promises applications in several advanced technologies, such as the creation of novel materials at the nano, micro and macroscales including, but not limited to, materials having photonic band gaps, quantum control of atoms and molecules as well as miniature condensed matter systems. Motivated in part by these potential applications, this Theme Issue provides a concrete up-to-date overview of vibrational and stochastic resonances in driven nonlinear systems. It assembles state-of-the-art, original contributions on such induced resonances - addressing their analysis, occurrence, and applications from either the theoretical, numerical and experimental perspectives, or through combinations of these

Vibrational and stochastic resonances in driven nonlinear systems:part two

Nonlinearity is ubiquitous in both natural and engineering systems. The resultant dynamics has emerged as a multidisciplinary field that has been very extensively investigated, due partly to the potential occurrence of nonlinear phenomena in all branches of sciences, engineering and medicine. Driving nonlinear systems with external excitations can yield a plethora of intriguing and important phenomena – one of the most prominent being that of resonance. In the presence of additional harmonic or stochastic excitation, two exotic forms of resonance can arise: vibrational resonance or stochastic resonance, respectively. Several promising state-of-the-art technologies that were not covered in Part One of this Theme Issue are discussed here. They include inter alia the improvement of image quality, the design of machines and devices that exert vibrations on materials, the harvesting of energy from various forms of ambient vibration, and control of aerodynamic instabilities. They form an important part of the Theme Issue as a whole, which is dedicated to an overview of vibrational and stochastic resonances in driven nonlinear systems. resonances in driven nonlinear systems

Effect of turmeric on shrimp (Penaeus semisulcatus) shelf life extension in chilled storage conditions

The present investigation aimed to evaluate the effect of turmeric on shelf life extension of shrimp Penaeus semisulcatus under chilled storage conditions by sensory (organoleptic parameters), pH, proximate and bacterial analysis. The experimental setup was grouped into six, head on (group I), head on coated with turmeric (group II), headless (group III), headless coated with turmeric (group IV), peeled (group V) and peeled and coated with turmeric (group VI) groups. Peeled shrimps coated with turmeric group retained their quality and their shelf life was extended up to 8 days of storage in ice (1:1). Significant differences (p<0.05) were found in the overall acceptability among the experimental groups of fresh and cooked shrimp. The level of pH, protein and carbohydrate varied (p<0.05) among the experimental groups. However no significant difference was found in the lipid and bacterial level in peeled shrimp coated with turmeric on the 8th day compared to other groups including the control. The sensory analysis, pH, protein, carbohydrate, lipid and bacteriological results of the present study proved that the application of turmeric in peeled shrimp stored in ice (1:1 ratio) extended its shelf-life up to 8 days

Bifurcations, Chaos, Controlling and Synchronization of Certain Nonlinear Oscillators

In this set of lectures, we review briefly some of the recent developments in the study of the chaotic dynamics of nonlinear oscillators, particularly of damped and driven type. By taking a representative set of examples such as the Duffing, Bonhoeffer-van der Pol and MLC circuit oscillators, we briefly explain the various bifurcations and chaos phenomena associated with these systems. We use numerical and analytical as well as analogue simulation methods to study these systems. Then we point out how controlling of chaotic motions can be effected by algorithmic procedures requiring minimal perturbations. Finally we briefly discuss how synchronization of identically evolving chaotic systems can be achieved and how they can be used in secure communications.Comment: 31 pages (24 figures) LaTeX.

Analytic Behaviour of Competition among Three Species

We analyse the classical model of competition between three species studied by May and Leonard ({\it SIAM J Appl Math} \textbf{29} (1975) 243-256) with the approaches of singularity analysis and symmetry analysis to identify values of the parameters for which the system is integrable. We observe some striking relations between critical values arising from the approach of dynamical systems and the singularity and symmetry analyses.Comment: 14 pages, to appear in Journal of Nonlinear Mathematical Physic
