Efficient management of feed resources using data mining techniques /
Feed is the largest input in any livestock enterprise and the rapid increase in feed prices and shortage of feed resources has been one of the major constraints for farmers, livestock industries, planners and the policy makers. This calls for prudent management of available resources and application of computing techniques can be one of the possible potential approaches. India is endowed with a wide range of feed resources varying widely in their composition and utility for different livestock species. Clustering of feed resource into different groups based on the composition can help in better feed management. To evaluate and to suggest a best technique for clustering feed resources, we have evaluated three clustering techniques viz. K-means, spectral k-means and auto spectral on two different data sets containing 236 and 106 feed resources with major constituents like crude protein, crude fiber ash, fat etc., . -
Assumptions of complete rationality and complete information in economics: A critique /
Economists conceived the discipline of economics to be a science of social relations. In fact they believed that social relations between individuals are moderated and regulated. The Physiocratic, Classical and Neo - classical school which firmly believed in human liberty considered this moderation to be a matter of self regulation1 and also that the laws controlling human association to be as clear as the laws of geometry. Contrary to this economists belonging to the utopian common wealth, and the Marxists school believed the same can be dealt out only through social control by the state.2 Irrespective of ones allegiance to any school of economic thought, human behaviour is central to the study of economics and to its place in knowledge structures as a social science. -
Situating censorship: A study of the politics of state and self in literary translations in Iran /
A nation’s culture flourishes by interacting with other cultures” (Razmjou). Cultural variety not only enriches our knowledge, but also acts as a guide towards the growth of a nation. It gives an insight about the basic human right practices of different cultures. The standard of culture of any particular nation can be gauged through various tools, but importance is given to literature, as it acts as a barometer to measure the cultural growth of the nation. To interpret any culture it is important to understand the beginnings of that particular culture and make an in-depth study of the progress of its civilization. The cultural evolution of any place is continuous and is a combination of many factors like geographic location, weather conditions prevalent, suitable food crops grown, its political policies, religious influences, its history and its present circumstances. The above factors directly or indirectly become responsible to blend and give shape to a culture. -
A study on emotional intelligence and work life balance of employees in the information technology industry in Bangalore, India /
Emotional Intelligence is a set of qualities and competencies that captures a broad collection of individual skills and dispositions, usually referred to as soft skills or inter and intra-personal skills, that are outside the traditional areas of specific knowledge, general intelligence, and technical or professional skills. Emotions are an intrinsic part of our biological makeup, and every morning they march into the office with us and influence our behavior. Emotional intelligence consists of five factors: Knowing one's emotions, managing emotions, motivating oneself, recognizing emotions in others, and handling relationships Goleman (1995). Researchers today are interested in finding the effects of emotional intelligence on employees and thereby, organizations, and analyzing the various other facets of EQ. Emotional intelligence improves individual and organizational performance. -

Current status of e-governance in healthcare in the large hospitals of Bangalore /
Healthcare industry has seen a lot of transformation and innovation over the years. It is coming forward as a recognised sector in India after Information Technology and Pharmaceutical. But despite this Indias healthcare infrastructure has not kept pace with the economies and the sectorial growth. Enormous amount of resources have been spent but very little change on actual health status is noticed. This study is undertaken to assess the current status of e-governance (ICT) in large hospitals and try and find out the awareness and accessibility of e-governance to the patients. The survey conducted in hospitals involved the patients responses and responses from the Healthcare Professionals (HCPs). An attempt has been made to find out the effectiveness of various ICT applications in the healthcare like EHR/ EMR or Telehealthcare. Majority of the research on e-governance focussed on overall effective governance and administration but very few studies have been done to highlight the status of e-governance in healthcare in India. -
Inverse domination number of graphs /
Konigsberg (55.2 o North latitude and 22 o East longitude) was a city in Russia situated on the Pregel River,which served as the residence of the dukes of Prussia in the 16th century. Today,the city named Kaliningrad,is in Lithuania which recently separated from U.S.S.R.It serves as a major industrial and commercial centre of western Russia.The river Pregel flowed through the town,dividing it into four regions,as in the following picture.In the eighteenth century, seven bridges connected the four regions.The problem was to start from anyone of the land areas,walk across each bridge exactly once and return to the starting point.This problem was first solved in 1736 by the prolific Swiss Mathematician Leonhard Euler, who, as a consequence of his solution invented the branch of Mathematics now known as Graph Theory. -
Influence of radiative transfer on Rayleigh-Benard-Marangoni canvection 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. -

Effect of temperature modulation on Rayleigh-Benard convection in a rotating layer of a ferromagnetic fluid
The stability of a rotating horizontal layer of ferromagnetic fluid heated from below is examined when, in addition to a steady temperature difference between the walls of the layer, a time-dependent sinusoidal perturbation is applied to the wall temperatures. Only infinitesimal disturbances are considered. The effects of the oscillating temperature field are treated by a perturbation expansion in powers of the amplitude of the applied field. The onset criterion is derived when the condition for the principle of exchange of stabilities is valid. The shift in the critical Rayleigh number is calculated as a function of the frequency of modulation, magnetic parameters, Taylor number and Prandtl number. The effect of various parameters is found to be significant for moderate values of the frequency of modulation. It is shown that, when the thermal excitation is symmetric, supercritical motion is more pronounced for low Prandtl number ferro fluids. Further, for the case in which only the bottom wall temperature is modulated, the effect of rotation is to stabilize the system at low frequencies and the opposite is true for moderately large frequencies. The problem throws light on external means of controlling convection in ferromagnetic fluid applications. -

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. -
A study on the family environment of persons with thalassemia major
The objective of the study was to assess the family environment of persons with thalassemia major disorder. The clinical profile of the persons with thalassemia, the family awareness about the disorder and the social, financial, emotional and the couple relationship aspects due to thalassemia were also studied. The parents of the persons with thalassemia major were included in the study. Interviews were carried out with each of the subjects using a standard questionnaire to assess the family environment. The other aspects were studied using a semi structured questionnaire. The results show that 42 percent has a family income of less than 5000 Rupees per month. There is no mutual emotional support among 54 percent of the couples. 66 percent of the parents are not involved in any social activities. 14 percent of the parents feel burden and another 14 percent feel burnout and 38 percent are anxious about the sick child. The relationship with the non thalassemic child in the family is affected among 55 percent of the parents. 86 percent of the parents are aware about the need of iron chelation and the genetic nature of thalassemia. Family environment is significantly affected by the duration of the illness, treatment cost, number of thalassemia persons in the family, lack of awareness on the genetic nature on thalassemia. Hospital admissions restrict the recreational activities and also lead to lose of control in the family. Organization in the family is significantly affected where there is more number of persons with thalassemia. The subjects assessed expressed varying concerns about the family relationships, life long illness of the child and other psycho social issues. They feel that their competitiveness, career development, financial needs and relationships with their spouse and with their normal child are hampered by the illness of the child. It establishes that various psycho social interventions are imperative for such families. -
The correlation between work locus of control and occupational stress among team leaders working in it companies in Bangalore
Job related stress is one of the highest health risks influencing employees, regardless of the size of the organization or the work sector. Most of the researchers view stress as an interaction between the person and some environmental event or stressor. Job stressors are defined as job demands, constraints, and or opportunities and job related events or situations that might affect the individuals feelings of stress. The fact that employee stress is an increasing problem in almost all organizations has indeed been the driving force for a variety of researches on occupational stress. The literature on occupational stress recognizes its inevitability in many jobs where pressures of work begin to build up and cause adverse strain on the emotion of employees, their thought process and their physical condition. Stress vulnerability has also been major focus to determine how stress effects differently across similar jobs. During the 1980s, personality[Type A/ Type B, locus of control] was found to be related to job stressors[ work load, role conflict, lack of autonomy], job strains[ job dissatisfaction, anxiety, health complaints]. The research aims to investigate the relationship between Work locus of control and occupational stress of team leaders working in IT companies in Bangalore. The purpose of research is to study whether the team leaders have an internal or external locus of control, which in turn determines how they perceive situations and life events, and how stressed they are due to this. It was hypothesized that the higher the internal locus of control of the team leader, the lower level of occupational stress they experience and the higher the external locus of control of the team leader, the higher the level of occupational stress. A sample of 100 team leaders working in three different IT companies were examined by administering the Occupational stress index by AP Singh and AK Srivastava and Work locus of control scale by Paul E Spector. The extent of work stress was examined on its twelve sub-scales, i.e. role overload, role ambiguity, role conflict, unreasonable group and political pressure, responsibility for persons, under participation, powerlessness, poor peer relations, intrinsic impoverishment, low status, strenuous working condition and unprofitability of Occupational stress index. A structured questionnaire was designed to gather information on the socio demographic profile of the respondents. The statistical analysis was done using SPSS. The level of significance was fixed at 0.005(p<0.005). Correlational analysis reveals that team leaders with external locus of control score high on all twelve sub scales of occupational stress and team leaders with internal locus of control have low scores on all twelve sub scales of occupational stress i.e. role overload, role ambiguity, role conflict, unreasonable group and political pressure, responsibility for persons, under participation, powerlessness, poor peer relations, intrinsic impoverishment, low status, strenuous working condition and unprofitability. There is a significant difference with regard to occupational stress between team leaders with external locus of control and team leaders with internal locus of control. The correlation between occupational stress and external control was found to be positive and significant as predicted (p=<0.001). The correlation between occupational stress and internal control was found to be positive and significant as predicted (p=<0.001).
