A study of the effectiveness of technology enabled learning strategy based on multiple intelligences on the achievement in history and civics of elementary school students in Bangalore
Education in ancient India in its traditional form was closely related to religion and was limited to a very small section of Indian society. Ancient education in India followed an oral tradition, which laid stress on memory. Subjects like arts and sciences related to government: politics, economics, philosophy, and historical traditions were taught (Thapar, 2002). With the arrival of Islam in India, the traditional methods of education underwent a change. Islamic institutions of education in India taught grammar, philosophy, mathematics, and law influenced by the Greek traditions inherited by Persia and the Middle East, before Islam spread from these regions into India. A feature of this traditional Islamic education was its emphasis on the connection between science and humanities. -
A study on induced path decompositions of graphs
A graph is a discrete structure consisting of a set of objectscalled vertices and another set of objects called edges depicting the relationship between pairs of vertices. Therefore, graphs serve as effective models to study networks of all types such as computer networks, telecommunication networks and social networks. The concept of a graph possesses the unique combination of features like simplicity, visibility, beauty, clarity, elegance and effectiveness
in studying problems dealing with network structures. It might be a simple structure like that of an organizational structure in a college, a complex structure like the world wide web (www) or just an abstract structure consisting of objects that are inter-connected according to some rule. -
A framework for integrating nested queries in natural language interfaces to databases
To translate Natural Language (NL) statements into Structured Query Language
(SQL) queries, different methods and systems were proposed in the past. This work presents a framework for automating the translation of Data Requirement
Specifications (DRS) given by enterprise Business Users in NL into SQL queries,
focusing on requirements that result in the generation of nested SQLs. The framework takes the business user’s DRS given in English as input and generates an initial query sketch by employing semantic parsing. This initial sketch is further refined and completed into a well-formed SQL by consulting the Database Schema. It performs the translation by combining NL processing techniques with Query Sketch generation methods and refines it by employing Repair techniques or extends it further. The framework suggests using Lambda expressions for intermediate representation and employs standard operations of Lambda Calculus for performing the required transformations needed for translation. Lambda Context Calculus (LCC) provides the operational semantics and the relevant methods needed in transforming NL statements into SQL, preserving the integrity and compositionality24 of expressions in every step of the translation. Though Lambda Calculus is found to be effective in representing the intermediate expressions and assists in performing the transformations that are needed for translating specific predicates into SQL, its inflexibility in combining parallel computations is a constraint. To represent clauses that are in parallel or are in
pipeline, and to perform the required transformations on the intermediate expressions involving these, more advanced programming constructs are needed. It also adopts functional programming techniques to deal with complex scenarios involving nested queries. This work recommends the use of some advanced language constructs, the Fixed-point Combinators11 and Monad Comprehensions20 for performing the required transformation at the intermediate language level and adopts functional programming techniques for the required syntactic sugar. -
Empowering women living with HIV/AIDS-A study on organisational strategies and challenges
The acts of discrimination & exclusion meted out to the people living with HIV/AIDS, and the stigma attached to the condition deprives the afflicted, of their capacity to exercise their fundamental rights and to access basic necessities. Specifically, the suffering of the women stricken by this chronic, incurable malady, the majority of whom from economically weaker sections of our society is very poignant. From the time this pandemic broke out in 1984, world organisations, national and local organisations, both government and non-government have come to the aid of the PLWHA. Some of them cater singularly to the needs of the WLWHA, who are as such more vulnerable ever since the plight of the women living with the deadly disease was brought to light. But as the years went by, there has been a decline in the help extended to the WLWHA. This study is undertaken to ascertain the current state of services and strategies used by the organisations to empower the WLWHA and the challenges faced by the organisations in their endeavours. -
Study of linear and non-linear analyses of Rayleigh-Benard-Chandrasekhar convecion in micropolar fluid with saturated porous medium
Thermal instability of Chandrasekhar convection in a micropolar fluid, saturated porous layer is being investigated in this study. The model is confined between two horizontal plates of infinite length and separated by a fixed distance. A uniform temperature gradient is provided at the lower plate, while the upper plate is cooled. The study is analysed for both linear as well as non-linear cases to understand the stability, transfer of heat and mass within the model. The study is carried out in extending the model for Rayleigh-Benard and double diffusive convection with external constraints such as in- ´
ternal heat, concentration source, gravity modulation, temperature modulation, coupled cross diffusion and throughflow. The outcome of the study is discussed in detail and presented pictorially through graphs. -
A study of thinking style, teacher effectiveness and emotional intelligence of secondary school teachers of Bangalore city
Education is a social process by which knowledge is transferred to students through the intermediaries, the teachers. It can be had from non - formal and formal systems of Education. All formal systems are based on the classroom teaching. "The destiny of India is being shaped in her classroom", has been pointed out by the Indian Education Commission (KOTHARI COMMISSION) (1964-66) and to that, it may be safely added that the destiny of these classrooms is being shaped by the teachers. According to the American Commission, the quality of the nation depends upon the quality of the citizens. The quality of its citizens depends, not exclusively, but in critical measure upon the quality of their Education. The quality of their education depends more upon the quality of teachers. Humayun Kabir rightly said once, "Without good teachers even the best of system is bound to fall, with good teachers, even the defects of a system can be largely overcome". The teacher is the flywheel of the whole educational machine. Elaborate blue prints, modern school plans, the best equipment, the newest of the new
media or progressive methods will remain dead fossils unless there is the right use of teachers. The document, Challenge of Education -A Policy Perspective (1985) has highlighted that teacher performance is the most crucial input in Education. No development has reached the threshold of development of new technology which is likely to revolutionize the classroom teaching. -
Multi-component condensation mediated synthesis of bioactive heterocyclic compounds
Aromatic heterocycles constitute the most diverse family of organic compounds. Moreover, aromatic heterocycles are widely used for the synthesis of dyes and polymeric materials of high value. The development of selective reactions that utilize easily available and abundant precursors for the efficient synthesis of heterocyclic compounds is a long-standing goal of chemical research. Despite the centrality of its role in a number of important research areas, including medicinal chemistry, total synthesis,and materials science, a general, selective, step-economical, and stepefficient synthesis of heterocycles is still needed.Pyrano[2,3-c]pyrazole derivatives have been synthesised by a one-pot multicomponent condensation of different aldehydes, dialdehydes, and ketones with malononitrile, ethyl acetoacetate, hydrazine hydrate (or phenylhydrazine) in the presence of magnetic nano-[CoFe2O4] catalyst under ultrasonic irradiation. The catalyst can be retrieved using an external magnet and used repeatedly. A practical, scalable method for obtaining various pyranopyrazoles has been demonstrated.

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 expectations from the employer is now shifted from monetary to more intrinsic values like rewards, recognition, and flexible work. Understanding 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 resource managers to collaborate with marketing team to develop right communicating 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
understand 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 to 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. -

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 behavioral traits associated with the person. The biometrics identifies the person based on features vector derived from physiological or behavioural characteristics such as uniqueness, permanence, accessibility, collectability with minimum cost. The physiological 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. -
Development and effectiveness of an art therapy application for children
This study involved developing an art therapy app and explored the effectiveness of art therapy using the app on enhancing children's’ self-esteem. Digital technology has become a part of human life and has also influenced mental health services. There is a recommendation to use digital technology in low-resource countries to bridge the mental health service gap for individuals with mental health problems. To meet the needs of art therapists and clients, an app called ‘Art about Me’ was designed as a new medium/tool in art therapy intervention by the researcher, an art therapist. Confidentiality, security, documentation, and a backing up system were the primary features considered while developing the app. Three school counselors who participated in an art therapy workshop provided art therapy intervention using the app for children in school settings to improve their self-esteem. The results indicated that art therapy using the app was significantly effective in enhancing their self-esteem. This study concluded that the app could replace traditional art materials and work as a substitute medium. It helped build a therapeutic
alliance with clients, develop self-growth and potential for children, and was appreciated by counselors. The art therapy app would be an adequate solution to provide therapeutic services and overcome the limitation of art materials for art therapy, especially in low resource countries. -
Effect of personality, psychological capital, institutional support on job satisfaction and affective commitment among private school teachers on 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. -

Organic and inorganic compounds anchored graphene frameworks as materials for sensor and supercapacitor applications
The specific atoms or group of atoms that can attach to the other organic or inorganic compounds due to the strong affinity is called as the anchoring group. The electrons from these organic and inorganic compounds are potent to travel through the anchor group. This leads to specific features with the change in the arrangement of atoms in the entire molecule/system. Hence, the redox reaction properties, molecular chain length and the extent of conjugation of the resultant anchored product vary. Depending upon the binding nature, anchoring groups can be divided into monodentate, bidentate, and multidentate. Among these, multidentate anchoring groups are more significant since it can bind either partially to the molecules or withthe whole surface. Though many multidentate anchoring groups like fullerene, carbon nanotubes, polymers, calixarenes, and graphene are presented in the literature, graphene oxide anchored organic and inorganic compounds are important because of its amazing contributions to the material science and design. The high thermal and electrical conductivity, large surface area, mechanical strength, and availability of more mobile electrons make graphene as the suitable anchor group for diverse applications in the field of adsorption of polluted gases, catalyst for the organic conversions, medicinal chemistry, electrochemical sensing, and energy storage devices. Therefore, Graphene oxide (GO) is one of the good choices to develop supercapacitance systems and electrochemical sensing materials. Heteroatom doping, conducting polymer, metal complexes, and metal oxides anchored graphene oxide are more significant because they change the electroactive properties significantly. Considering these, we studied the photophysical and electrochemical properties of chromium complex anchored GO synthesised by silane and diazonium coupling. The results exhibited that both silane functionalized GO and azo dye enable an electronic interaction due to the recombination of sp2 and sp3 states and electron-hole pairs which have extensive importance in developing optoelectronic devices. -

An investigative approach to hard machining of inconel 718 with coated carbide tool
Super alloys sustain good strength at high temperature and pressure conditions. Such
materials have high demand in Aerospace industry, Marine industry, and Nuclear power plants. They have a great demand in Nuclear and Aerospace applications because of it retain its properties at temperature over 700 °C. Machinability of nickel based super - alloys is extremely poor, mainly due to their low thermal conductivity, build up edge and self-hardening, which leads to high dynamic cutting forces. They are difficult to machine because of its high shear strength, work hardening and precipitation hardening. High abrasive particles in its microstructure and tendency forming chip to weld to tool and form Built Up Edge (BUE) make it more difficult to machine. Friction between tool and material and its low thermal conductivity results in high temperature generation. They have Nickel (Ni), Chromium (Cr), Ferrous (Fe) or Cobalt (Co) as base contains. Small amount of Al, Ti, Nb, Ta, W, Mo added to these alloys to sustain at high temperature. Chromium is important alloying element in order to obtain the hot corrosion resistance property. Due to these factors the tool wear is extremely high and increasing the tool life by minutes is an enormous success. To overcome this situation, various materials have been developed for Inconel 718 machining. Though Ceramic tools, Silicon Carbide whiskers, reinforced alumina tools, carbide tools have been used to machine Inconel 718 but they have failed to produce good surface, better accuracy and minimum tool wear. -
Studies on single crystals and thin films on tin sulfide (SnS) for photovoltaic applications
There is an increasing demand for renewable energy sources due to the limited availability of fossil, risk factor associated with nuclear fuel and due to growing environmental concern. Photovoltaic (PV) energy conversion has the potential to contribute significantly to the electrical energy of the main obstacles preventing production and application on a large scale. Availability of the materials and their processing cost are the two major constraints associated with the presently leading PV technologies. Hence, cost of the electricity produced by these technologies are not yet competitive compared to the electricity produced by conventional sources. -
Elemental abundances in the interstellar medium
One method to investigate the chemical composition of the interstellar medium (ISM) and interstellar dust grains is to conduct interstellar elemental depletion studies, especially of highly abundant species. The role refractory element, silicon (Si) in extinction is not clearly understood and the distribution and evolution of moderately volatile sulfur (S) in the ISM is still an open problem. The key motivation of the work is to investigatethe chemical composition of ISM of our Galaxy, and the formation, processing and distribution of interstellar dust in its different environments, mainly focusing on silicon and sulfur abundances, both in gas and dust.In the work outlined in this thesis, I will be describing the gas and dust phase abundances of Si and S in the interstellar medium using archival observations, and their probable role in the observed extinction. In this work, we also have measured the column density of S II along 9 Galactic sight lines using archival high-resolution observations from the Space Telescope Imaging Spectrograph and determined the abundances of S in both gas and dust phases. Using Archival spectral data towards 131 target stars in the Galaxy, interstellar Si abundances and depletion along those lines of sight has been surveyed. Oscillator strength correction has been performed to account for its improvements, using most recent values. This is an extensive survey done using a much larger data sample compared to previous investigations, but it substantiate the majority of the findings, which show that Si depletion is linked to both the average hydrogen density (n (H)) and the fraction of molecular hydrogen (f(H2)) along the lines of sight.
