Effect of personality psychological capital institutional support on job satisfaction and affective commitment among private school teachers in south karnataka
A teacher's personality traits are important to create and maintain a classroom learning environment. The behaviour of Teachers depends on the characteristics of the personality. There have been many pieces of research based on the positive aspects of teachers' behaviour through enhancing some psychological states which are based on the positive institutional behaviour. This particular research has its focus on the positive strengths of the teachers, and this construct has an essential influence on job satisfaction. Hence, a satisfied and engaged teacher is very much necessary to strengthen the competitive student base of every School. To explore the fact, the researcher has chosen the constructs such as Personality, Positive psychological capital, Institutional factors (Perceived Institutional support, Work-life policies, Work autonomy), Job satisfaction factors, and Affective commitment to study the impact of the Big five dimensions of personality on job satisfaction and affective commitment of private school teachers in South Karnataka and to investigate the impact of psychological capital on job satisfaction and affective commitment of teachers. The study also attempts to understand the influence of Institutional factors (perceived Institutional support, work-life policies, and work autonomy) on job satisfaction and affective commitment. Also, the study explores the influence of job satisfaction on the outcome factors namely affective commitment among private school teachers. The study used a descriptive research design, and it is observed that the total number of districts in south Karnataka is fifteen. The researcher selected four private schools from each district randomly with the help of the private school list used as a sampling frame. The total sample size for the study estimated were 477 teachers working in private schools. The study has analysed the data using appropriate statistical tools such as (i) frequency analysis, (ii) Factor analysis, (iii) ANOVA with post hoc (v) Regression analysis. The study concludes that when the private school teachers personalities such as extraversion, agreeableness, conscientiousness, and openness to experience which will tend to significantly influence Job satisfaction among teachers working in the private schools of South Karnataka. Similarly, private school teachers Psychological capital like resilience, self-efficacy, optimism, and hope which tend to influence job satisfaction at their work significantly. This study also concludes that private school teachers to be given proper work-life balance and work autonomy by the school management, which will significantly influence job satisfaction among the teachers at work. Also, private school teachers who possess personalities such as extraversion, agreeableness, conscientiousness, and openness to experience significantly influence the teacher's affective commitment. The study also reveals that the private school teachers have Psychological capital like resilience, Self-efficacy, Hope, and Optimism, which tend to significantly influence their affective commitment which will reflect towards their respective institution. If the private institution gave the school teachers proper work-life balance and work autonomy, then they tend to influence their affective commitment significantly. Also, it is concluded that the affective commitment of teachers significantly influences the job satisfaction level of school teachers. This implies that the school management can enhance the level of teachers' commitment to their schools by creating a more conducive and more satisfying environment in the workplace. Accordingly, schools can decide on pay and other monetary incentives. However, they can enhance teachers' job satisfaction by creating better training and development opportunities, improving leadership and management support, promoting accountability, and involving teachers in decision-making made at the school level. Another important finding of this study is the observed positive relationships between scores of job satisfaction and organizational commitment. Some of these findings contradict the existing literature in these fields; others are inconsistent with the prevailing literature. -
Role of employee value proposition in creating employer brand value for employee attraction and retention
Employee Value Proposition is a set of associations and offerings provided by an organisation in return for the skills, capabilities and experiences an employee brings to the organisation. Employee newlineexpectations from the employer is now shifted from monetary to more intrinsic values like rewards, recognition, and flexible work. newlineUnderstanding the value proposition is vital to devise appropriate human resource strategies for employee attraction and retention. Human resource managers have realised that the communicating the value propositions to the employees is as important as devising them. This has led human newlineresource managers to collaborate with marketing team to develop right newlinecommunicating strategies to build a lucrative employer brand to attract right talent into the organisation. Previous studies lack focus on dual outcomes of employer brand. The current study develops an employer brand for internal employees and potential employees. Although the value proposition components remain same for both category of employees, the order of preference differs. The study has used structured questionnaire to newlineunderstand the order of preference of value proportion components for internal and potential employees among generation X, Y and Z. The findings assist human resource managers to use the developed framework newlineto identify the value proposition preferred and develop and communicate the Employee Value Proposition accordingly. The theoretical contribution includes proposing differentiated Employer Brand framework for internal and potential employees. -
Rayleigh-benard and benard-marangoni convection in micropolar fluid
We study in this thesis, Rayleigh-Bard and Bard-Marangoni convection in a micropolar fluid. We study the effects of temperature modulation at the boundary and gravity modulation in the presence of porous medium. The effects of rotation and internal heat generation are also investigated and results are presented graphically and discussed qualitatively. The problem presented in this thesis throws light on externally controlled internal convection in a micropolar fluid. These problems have many possible applications in geophysics, astrophysics, oceanography engineering and in space situations with g-jitter connected with gravity stimulation study. With this motivation, we examine in this thesis five problems and their summary is given below one by one. (i) THE EFFECT OF IMPOSED TIME-PERIODIC BOUNDARY TEMPERATURE AND POROUS MEDIUM ON THE ONSET OF RAYLEIGH-BARD CONVECTION IN A MICROPOLAR FLUID The analysis of buoyancy driven convection in a micropolar fluid saturated porous layer heated from below and subject to temperature modulation is presented. In addition to a steady temperature difference between the walls of the porous layer, a time-dependent periodic perturbation is applied to the wall temperatures. The small amplitude of the modulation is used to compute the critical Rayleigh number and critical wave number. Three cases of the oscillating temperature field are examined: (a) symmetric, so that the wall temperatures are modulated in phase, (b) asymmetric, corresponding to out-of-phase modulation, and (c) only the bottom wall is modulated. Possibilities of the occurrence of subcritical instabilities are also discussed. The shift in the critical Rayleigh number is calculated as a function of frequency and it is found that it is possible to advance or delay the onset of convection by time modulation of the wall temperatures. (ii)LINEAR AND NON-LINEAR ANALYSES OF GRAVITY MODULATION ON THE ONSET OF RAYLEIGH-BARD CONVECTION IN A MICROPOLAR FLUID WITH POROUS MEDIUM. -
Study of Three-Dimensional Mapping of Interstellar Extinction in Milky Way Galaxy
The Ultraviolet Imaging Telescope (UVIT) is scheduled to be launched as a part of the ASTROSAT satellite. As part of the mission planning for the instrument we have studied the efficacy of UVIT observations for interstellar extinction measurements. We find that in the best case scenario, the UVIT can measure the reddening to an accuracy of about 0.02 magnitudes, which combined with the derived distances to the stars, will enable us to model the three-dimensional distribution of extinction in our Galaxy. The knowledge of the distribution of the ISM will then be used to study distant objects, affected by it. This work points the way to further refining the UVIT mission plan to best satisfy different science studies. newlineWe report here on our plans to use data from the Ultraviolet Imaging Telescope (UVIT) aboard the ASTROSAT mission to probe the extinction across the entire sky. This mission has been in develonment since 2000 (Agrawal 2001) and is expected to be launched on a Polar Satellite Launch Vehicle (PSLV) rocket by the Indian Space Research Organization (ISRO) in 2013. The UVIT instrument is being developed at the Indian Institute of Astrophysics (IIA) and includes three telescopes, two in the ultraviolet (FUV and NUV) and one in the visible, each including a filter wheel with a number of different filters (Kumar et al. 2012). We have run a series of simulations to determine which filters are best suited for our purpose and will use these results in planning our observations with the UVIT. -
Motivational Behaviour of Tourism Employees in Relation to Organisational Culture and Career Orientations
The productivity and effectiveness of any organisation depends mainly on the performance level of the employees in the organisation. Human behaviour scientists over the years have conducted various studies and have concluded that, the performance of employees in any organisation depends largely on their motivational behaviour. Reviews of related literature confirm the role of various factors in the motivational behaviour of employees including organisational culture and career orientation of employees. The title of the present study is Motivational Behaviour of Tourism Employees in Relation to Organisational Culture and Career Orientations. The major objectives included ascertaining the relationship between motivational behaviour and organisational culture and career orientations of tourism employees and finding out whether differences in demographic variables would account for significant differences in motivational behaviour. The population of the study consisted of 323 employees of public sector, private sector and multinational companies working in travel agencies, tour operations, airlines and hotels and resorts in Bangalore. The sampling technique employed was judgment sampling. For the present study three tools namely: Motivational Analysis of Organisations- Behaviour (MAO-B) by Pareek (2003), Organisational Culture Survey by Pareek (2003) and Career orientations Inventory by Schein (1990) were used to collect data. The findings of the study show that while two aspects of organisational culture namely internal and future oriented influence the motivational behaviour of employees working in the private sector, no aspect of organisational culture has any influence on the motivational behaviour of employees working in the public sector. Further, only ambiguity tolerant aspect of organisational culture influence the motivational behaviour of employees working in multinational companies. -

Study of substituion effectson structure and properties of high temperature superconductors and isostructure compounds
The thesis mainly describes the investigation of the structural formation of higher order members of bismuth system of superconductors Bi1.6sPb0.35Sr2CazCu4Oy (n = 4, 2234 phase), Bi1.6sPb0.35Sr2Ca4CusOy (n = 5, 2245 phase) and Bi1.65Pb0.35Sr2CasCu,Oy (n = 9, 2289 phase). The samples were synthesized by solid state reaction technique. Micro-structural and morphological features of the synthesized samples were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDS). The XRD pattern of all the samples revealed the presence of Bismuth 2212 and 2223 phases of which 2223 phase was found to be the predominant. Superconducting transition temperature (Tc) of the samples measured by self-inductance method and dc four probe method showed Tc value around 110 K. There was no signature of the formation of 2234, 2245 or 2289 phases in this investigation. newlineFormation of Bi-2245 compound was further investigated by preparing the sample in a new matrix route. The Tc on set of this sample was found to be 127 K which was the highest reported ever in bismuth system superconductors. The complete replacement of copper by nickel in bismuth system superconductor Bi2SraCu06 (2201) was ttempted by preparing the sample in air by solid state reaction method under open and closed environment. Morphological and microstructural features of the synthesized sample Bi2Sr2Ni0g was investigated by X-ray diffraction, SEM and EDAX. The analysis of X-ray diffraction pattern revealed that nickel can replace copper completely and form a single phase Bi2Sr2Ni06 only when prepared in a closed environment in air. This phase formation of BizSr2NiOo was reported first time. -
Purchase intention of deconstructed end-of-lifecycle fashion products in an online and offline retail environment
Obsolete or slow-moving inventory is one of the major influencers for the bottom line of any business today. Surplus stock- be it from overbuys, returns, defects or simply merchandise hitting the end of their lifecycle- need to be accounted, accommodated and dealt with in a manner that can least affect the planned margins. For the fashion newlinebusiness, such merchandise poses greater challenges. The business is ground by seasonal preferences, fast-changing trends, short lead-times and shorter shelf-lives. With rising costs of traditional retail businesses, the associated costs of carrying such inventory are something that the newlineretailer can easily do without. At the retailers end, such merchandise is newlineoften subjected to traditional liquidation methods such as Markdowns, carry forwards, or selling at lowered prices to discount stores or factory outlets. From a manufacturer s perspective, overruns from production newlineare either sold at discounted costs to the retailer or are diverted to other sources of sales. In either case, such decisions do affect the margins of the business, and retailers often account for these necessary evils while planning their pricing strategy. Liquidation methods for such obsolete merchandise also need to meet the additional challenge of maintaining the perceived value of the products, and to not adversely newlineaffect planned margins due to lowered price points. This study seeks to explore fashion consumers acceptance of Deconstructed or up-cycled fashion for such obsolete or EOLC (End-of-lifecycle) merchandise that newlineremain unsold. It also maps the Perceived value of such merchandise and explores the other factors that may affect the Purchase Intention of the merchandise, like the Internal reference price, Perceived monetary newlinesacrifice and Perceived quality. Through an experimental study, a comparative analysis is built across consumers in an E-commerce vs newlineOffline store purchase scenario, to derive if the method of presentation of such products affects the Purchase intention. -
Development of Efficient Biometric Recognition algorithms based on Fingerprint and Face
The reliable verification systems are required to verify and confirm the identity of an individual requesting their service. Secure access to the buildings, laptops, cellular phones, ATM etc. is an example of such applications. In the absence of robust verification systems, these systems are vulnerable to the wiles of an impostor. The traditional ways of authentications are passwords (knowledge based security) and the ID Cards (token based security). These methods can be easily breached due to the chance of stolen, lost or forget. The development and progress of biometrics technology, the fear of stolen, lost or forget can be eliminated. Biometrics refers to the automatic identification (or verification) of an individual (or a claimed identity) by using certain physiological or newlinebehavioral traits associated with the person. newlineThe biometrics identifies the person based on features vector derived from physiological or behavioural characteristics such as uniqueness, permanence, accessibility, collectability with minimum cost. The newlinephysiological biometrics are Fingerprint, Hand Scan, Iris Scan, Facial Scan and Retina Scan etc., and behavioural biometric are Voice, Keystroke, Gait, Signature etc., The physiological biometrics measures the specific part of the structure or shape of a portion of a subject s body. But the behavioural biometric are more concerned with mood and environment.Chapter one presents the introduction to biometrics and its various newlinetraits. Further description like structure of the biometric system, different newlineapproaches are discussed. Also the design issues in biometric system such as universality, collectability, distinctiveness, permanence, acceptability, newlineuniqueness, performance, circumvention etc., are discussed. Chapter two gives a detailed survey of biometric techniques. It includes the literature survey of fingerprint and face biometric traits and various approaches. -

Development and effectveness of a screening measure and a computerized cognitive remediation program for children with reading and arithmetic difficulties
Reading and arithmetic skills are considered as the foundation skills necessary for educational and vocational success. Research has outlined the important role of specific cognitive functions for efficient reading, comprehension of text and arithmetic processes. Learning difficulties have been shown to have a tremendous impact on later life, both in academics and social relationships. It therefore becomes newlineimperative that we identify, as early as possible, children at risk for learning newlinedifficulties and attempt to assess the relevant cognitive skills and plan and execute intervention programs to improve the efficacy of these cognitive skills. This present study has attempted to do this, keeping the Right to Intervention (RTI) model as the rationale and has focussed on designing an assessment tool along with a remediation program based on the cognitive viewpoint.The two objectives of this research were: development of a screening measure newlinefor identification of children with reading and arithmetic difficulties and development newlineof a computer based cognitive intervention program for improving reading and newlinearithmetic skills. The research was conducted in two stages. Stage one involved the newlinecompiling of the screening measure which consisted of three domains: cognitive newlineabilities, reading comprehension and arithmetic ability. The assessment measure was administered on 1091, third, fourth and fifth grade children from English medium newlineschools in South Bangalore, following the ICSE syllabus. The data obtained was newlinesubjected to item analyses and the final screening tool - Arithmetic and Reading Test newline(ART) - was developed, which comprised of tests for reading comprehension, arithmetic ability and cognitive functions, i.e., attention and concentration, visual newlineperception, visuo-spatial ability, processing and working memory. Psychometric properties were established and the ART was found to be reliable and valid. Test-retest reliability of the ART was 0.76.
