INFLUENCE OF RADIATIVE TRANSFER ON RAYLEIGH-B??NARD-MARANGONI CONVECTION IN A COUPLE-STRESS FLUID SATURATED POROUS MEDIUM
The problem of Rayleigh-Benard-Marangoni convection in a couple-stress fluid saturated porous medium with thermal radiation is studied within the framework of linear stability analysis. Only infinitesimal disturbances are considered. The linear stability analysis is based on the normal mode technique. The Darcy law is used to model the momentum equation. The fluid between the boundaries absorbs and emits thermal radiation. The boundaries are treated as black bodies. The absorption coefficient of the fluid is assumed to be the same at all wavelengths and to be independent of the physical state. The principle of exchange of stabilities is valid and the existence of oscillatory instability is ruled out. The expression for the stationary Darcy-Rayleigh number is obtained as a function of the governing parameters, viz., the wave number, the couple-stress parameter, the conduction-radiation parameter, the absorptivity parameter, the Marangoni number and the Biot number. The Galerkin method is used to determine the eigenvalues. The effect of various parameters on the stability of the fluid layer is discussed through figures and tables. -
COMPARATIVE ANALYSIS OF ORGINAL MOVIES AND ITS REMAKES IN INDIA
The remake is a phenomenon both well-known and immediately recognizable but in India it is not theoretically analyzed. However, by analyzing these remakes, we can understand how these films reflect some specific cultural differences between one state and other State in India. Here researcher has taken four original and its remake films to understand the phenomena of remake. The highly intensed watching the films has helped researcher to understand the difference of films original and remakes. Researcher took one Tamil Movie and its remake in Hindi and also a Malayalam Movie and its remake in Tamil. Films are Tamil Singam to Hindi Singam and Malayalam Manichithrathazhu to Tamil Chandramukhi. All the changes made in movies are on the basis of the cultural differences between the regions where the film is introduced. As researcher have done two Tamil movies he came to know that Tamil Industry possess one culture even though it is a remade they try to change it according to their culture. The basic element of films are the audience, a film is made according to them. So that film Industry sticks to the culture of the audiences. -
Mother Daughter Relationship: Daughters' Experience
This study explores daughters' experience of their relationship with their mothers, and how this relationship has been perceived and interpreted by them during different periods in their lives, starting from childhood till the time of their motherhood. Further it recognizes the changes in the mother daughter relationship and factors contributing to these changes over a period of time. The study also explores stressful times in the mother daughter relationship, and the impact that the mother has on the daughter. 11 married women with at least one child were interviewed using life history method and data was analyzed using Thematic Analysis. Findings indicated changes in daughters' communication with her mother over the life cycle and change in roles for the daughter as evident through role reversal and mutual mothering. Factors contributing to growth and change in the relationship were identified as the daughter experiencing wife and mother roles herself. Daughters' pregnancy, and birth of grand children have been identified as factors which evoked a lot of support from mothers. Further, adolescence was reported as a stressful period in the mother daughter relationship. In addition, the mother's values, and behaviour was found to have a direct or indirect impact on the role attitudes and behaviours of some daughters in the study. The power of the mother's influence lied in her implicit and explicit messages given to the daughter more than her actual role choice. Some mothers and daughters had gender based expectations for each other. -
PRICE DISCOVERY, CAUSALITY, CONDITIONAL VOLATILITY & FORECASTING IN INDIAN FUTURES MARKET: EVIDENCE FROM 2001 - 2011
This work investigates the price discovery, causality, conditional volatility and forecasting in S&P CNX Nifty spot Market returns and S&P CNX Nifty Future Market Returns. The overall data study is classified into In-sample and Out-sample observations and the research work has been carried out by using the daily data from 1st January 2001 to Dec 31st 2011. The Out-sample analysis is carried on from 1st Jan 2011 to 31st Dec 2011. The dataset for the above analysis was retrieved from www.nseindia.com. The research also refines down with long term and short term dynamics of prices between spot and futures market by using various forecasting models such as Root Mean Square Error, Mean Absolute Error, Theil??s Inequality U test etc for Out- sample observation. Apart from this, the In-sample analysis has been carried out by Market Model, Johansen Cointegration test, Granger Causality test, Vector Error Correlation Model and GARCH Model. The results of the above tests indicate futures become the base for building up the spot, the causality tests and response analysis function indicate that future prices tend to discover new information more rapidly than spot, and the hence this will indicate more accurate forecasts of spot prices but not the spot to future and this price discovery function of futures prices has strengthened of homogenous structure of Index over recent years and it is disseminated in price discovery and risk management functions Keywords: Price Discovery, NSE, Volatility, GARCH, Cointegration, VECM JEL Classification: C22, C32, F47, G11 -
EFFECT OF CORIOLIS FORCE AND NON UNIFORM BASIC TEMPERATURE GRADIENT ON THE ONSET OF RAYLIEGH B??NARD - MARANGONI CONVECTION WITH MAXWELL - CATTANEO LAW
The effects resulting from the substitution of the classical Fourier law by the non-classical Maxwell-Cattaneo law in Rayleigh-B??nard-Marangoni convection in a rotating Newtonian fluid are studied using the Galerkin technique. The effects of one linear and five nonlinear basic temperature gradients are studied on the onset of convection. In the case of Rayleigh ?? B??nard convection, the eigenvalue is obtained for free-free, rigid-free and rigid-rigid velocity boundary combinations with isothermal and adiabatic boundaries. In the case of Marangoni and Rayleigh-B??nard-Marangoni convection the eigenvalues are obtained for an upper free / adiabatic and a lower rigid / isothermal boundaries. A linear stability analysis is performed. The influence of various parameters on the onset of convection has been analyzed. The classical approach predicts an infinite speed for the propagation of heat. The present non-classical theory involves a wave type heat transport (SECOND SOUND) and does not suffer from the physically unacceptable drawback of infinite heat propagation speed. It is found that the results are noteworthy at short times and the critical eigenvalues are less than the classical ones. -

A STUDY ON THE SELF-ESTEEM AND SOCIAL RELATIONS OF ADOLESCENTS WITH LEARNING DISABILITY.
According to World Health Organization Learning disability is a state of arrested or incomplete development of mind. The most common learning disabilities are Dyslexia, Dyscalculia Dysgraphia, Auditory and Visual Processing Disorders and Nonverbal Learning Disabilities. Adolescents with learning difficulty have trouble expressing their feelings, calming themselves down, and reading non-verbal cues which can lead to difficulty in the classroom and with their peers. In India approximately 13 to 14 per cent of all school children suffer from learning disorders (Sadaket 2009). The social relationships of the adolescents with learning disability have a positive influence on their self esteem. It helps them to maintain a constructive relationship with their peers, teachers and parents. The study was focused to know the relationship of self esteem and social relation in adolescents with learning disability. The study was conducted among all the Adolescents with Learning Disability, in an alternative school in Bangalore. The size of the sample was 50 which include both genders and the sampling design was purposive sampling. Adolescents with learning disability of the age group 11 to 18 years were included for the study. The students level of self-esteem was assessed by using a 10-item scale developed by Rosenberg (1965). The Rosenberg Self- Esteem Scale was rated on a 4-point Likert scale ranging from 1 (strongly disagree) to 4 (strongly agree). The researcher reverse scored five items that were negative in nature so that higher scores would indicate higher level of self-esteem. The scale ranges from 0-30. Scores between 15 and 25 are within normal range; scores below 15 suggest low self- esteem. A semi structured questionnaire was designed to gather information on the socio demographic profile and social relation of adolescents with learning disability. A pilot study was conducted among 10 percent of samples and necessary modifications were made. The statistical analysis was done on the data using SPSS. The level of significance was fixed at 0.005(p<0.05). The results show that, among the total respondents, 62.0 percent of them are male respondents (n=31) and 38.0 percent are female respondents (n=19).56 percent of the respondents are being compared with their siblings by their parents. The study indicates that 44 percent of the respondents feel stressed due to parental pressure. The respondents who fall under the age group of 16-19 years have a higher self-esteem than the respondents who fall under the age group of 11-15 years. The study shows that, statically there is a significant relationship between the respondents relationship with parents with respect to respondents self-esteem. There is less significant relationship between the respondents relationship with peers with respect to respondents self-esteem. Present study indicates that, statically there is a significant relationship between the respondents relationship with teachers with respect to respondents self-esteem. Learning disability is a disorder which can be remedied using appropriate instructional strategies. The early identification helps in remedial teaching and building self-esteem. The present study indicates that adolescents with learning disability with better social relationship will have high self-esteem. Realizing the importance of self-esteem and its relationship with social relation, a multidisciplinary approach is required to initiate appropriate interventions in building self-esteem and teaching learning disabled child. Thus the learning disabled child can be mainstreamed effectively. -

Development of Positive Self: Exploring the Experiences of Psychotherapists
Mental health professionals cater to the needs of people in distress. They utilise cognitive and emotional resources to completely empathise with the clientele and it can often lead to distress because helping profession is more prone to burnout. The benefits of practicing psychotherapy outweigh the hazards if they can bring work-life balance by creating a boundary between personal and professional lives. The aim of the current study was to explore the meaning and significance of professional experiences in the development of positive self. Seven psychotherapists with minimum ten years of experience participated in the study. Using semi structured in-depth interviews details about professional experience and the impact on personal life was explored. The data was analysed using thematic analysis. The study found the indicators of positive self as high self esteem, high self efficacy, experiencing positive emotions, signs of wisdom, hopeful behaviour, high optimism, self regulation, experiencing gratitude and forgiveness. Work experiences and coping strategies influenced the development of positive self. The results of the study can be used in training programmes for psychotherapists and building the conceptual model of positive self. keywords: psychotherapists, positive self, positive emotional state, functional coping strategies, professional growth, prosocial behaviour -
Recommender Systems Using Semantic Web Technologies
Recommender Systems (RS) have risen in popularity over the years, and their ability to ease decision-making for the user in various domains has made them ubiquitous. However, the sparsity of data continues to be one of the biggest shortcomings of the suggestions offered. Recommendation algorithms typically model user preferences in the form of a profile, which is then used to match user preferences to items of their interest. Consequently, the quality of recommendations is directly related to the level of detail contained in these profiles. Through the review of related literature, it is evident that the genre of a movie is a major factor influencing user decisions about movies. However, the degree of membership of a movie to a genre is typically unavailable. Sometimes, certain genres memberships to a movie might not be assigned at all. Such genre membership information, if available, would provide a better description of items and consequently lead to quality recommendations. To capture complete information on content pertaining to different genre in movies, we have used two approaches ?? one that utilizes the available binary genre information and augments it by inferring the genre degree using the information available in folksonomies and another that does not rely on previous movie categorization but captures genres that manifest automatically when forming keyword clusters. Folksonomies or tags are user-defined metadata for items and embed abundant information about various facets of user likes and their opinions on the quality and the type of object tagged. The degree of genre presence in a movie is inferred by examining the various tags conferred on them by various users. Leveraging on tags to guide the genre degree determination exploits crowd sourcing to enrich item content description. Fuzzy logic naturally models human logic, allowing for the nuanced representation of features of objects and thus is utilized to derive such gradual representation as well as for modelling user profiles. Fuzzy user and object representations are leveraged for the design of both content-based as well as collaborative recommender systems. Experimental evaluations establish the effectiveness of the proposed approaches as compared to other baselines. We call this the Fuzzy User-Based Recommendation Approach (FUBRA). Keywords related to a movie indirectly contain information related to the various narrative styles. User profiles are also constructed based on user preferences for such keyword clusters. We call this the Keyword Clustering-Based Recommendation Approach (KCBRA).These profiles are then utilized to perform both Content-Based (CB) filtering as well as Collaborative Filtering (CF). This approach scores over the direct keyword-matching, genre-based user profiling method and the traditional CF methods under sparse data scenarios as established by various experiments. -
The Living Conditions of Zeliangrong Tribe Residing in Tamenglong District
Having awareness and knowledge on the basis of population is imperative and a crucial step in effective planning programme, implementing and delivering services for all areas. The attempt with this research is to shed more light on the conditions that these ethnic groups live in. Negligence and backwardness of the study population are stretched to the extent that even literatures are scarce. The aim of the present study is describe the living conditions of Zeme, Liangmai, and Rongmei of Zeliangrong tribe residing in Tamenglong District in relation to socio economic dimension with an objective to document the demography, objective and subjective living conditions to find association with the living condition in relation to Sub-Tribes. A total of 132 sample households were participated. Descriptive research design is adopted and purposive sampling was selected. Results confirmed that Road and transportation, Health care and Sanitation facilities, Quality education, Supply of electricity and water, Income and Recreation facilities are found to be an utmost necessary intervention among this community. Even a simple analysis of the tribal people and the district clearly shows that they are in great need of attention. It is found that even within same ethnic community, there is a variance in the needs of the people which is reflected in the living condition. Geographical location itself offered a major contributor variable to accessibility. It depicted the lopsided paradigm of development. In a nation which is built on the ideals of the democracy, leaving behind any tribe or community or people is unacceptable in more ways than one. It is only logical to suggest that who brings development should also make development accessible to the people the development is intended for. Accessibility is not a magic wand that could instantly make the problems disappear into thin air. Accessibility to quality services could only make development meaning and would serve its purpose. A decent standard of living adequate nutrition, healthcare, quality education, work and protection are not just developmental goals, they are also human rights. Human rights are essential for full human development (UNDP, Human Development Report, 2000). The present study is an appeal for an action on behalf of this community who has contributed in small or big way for the development of our country to obtain their rightful share of human rights.

Rewriting Epic as a Discourse of the Marginalized: A Study of Mahasweta Devis Select Fiction
The present dissertation engages itself with an analytical study of five short stories by Mahasweta Devi, where she has rewritten episodes from the grand narrative The Mahabharata. Her stories The Five Women, Kunti and Nishadin, Souvali, Draupadi and Bhishmas thirst have been chosen for being studied in order to show how Devi counter narrates the grand epic by looking at the religious battle of Kurukshetra and the canonical epic characters from the subaltern perspective and thus creates a discourse of the marginalised. The critical framework of the study is based on a postcolonial and subaltern study of the texts as the principal characters and Devis themes are anti-canonical and anti- hegemonic. Through Devis feminist rewriting of the ancient text the subaltern sections of the society, who have been marginally represented in the canonical text, have been given a chance to speak. A readers understanding of the epic undergoes a change by going through the rewritten stories which is Devis main intention behind rewriting The Mahabharata. Through her writing she challenges the age old notions and long established truths in the epic for which it has been granted an epic stature. Thus she makes an attempt to lend a voice to the voiceless by this narrative technique and fulfils her social commitment as a journalist and activist writer.
