K shell X-ray Fluorescence Parameters of Platinum and Lead
X-ray fluorescence phenomenon (XRF) has gained importance as a tool the fields of atomic, nuclear and radiation physics, material science, medical physics, and in such diverse fields as industry, agriculture, archaeology, forensic science and so on for elemental analysis. This demands for accurate values of XRF parameters such as shell wise and sub-shell wise x-ray fluorescence yield, fluorescence x-ray production cross-section, Auger transition rate, shell and sub-shell intensity ratios, K to L vacancy transfer probabilities and so on. In addition, measurements of these parameters are useful in obtaining physical parameters such as photoelectric cross-sections, jump ratios and x-ray emission rates. Over the years several researchers have measured these parameters employing variety of methods and detectors (Apaydin and Tira?o?lu 2012; Hopman et al. 2012; Kahoul et al. 2011; Cengiz et al. 2011; Cengiz et al. 2010; M??nesguen and M. -C. L??py 2010; S????t et al. 2009a; S????t et al. 2009b; Reyes-Herrera and Miranda 2008; Ertu?rul et al. 2007; Aylikci et al. 2007; Demir and ?ahin 2007; ?ahin et al. 2005; ??zdemir et al. 2002; ?imsek et al. 2002; Durak et al. 2001; 1998; Allawadhi et al. 1993). However these methods involve complicated single and double reflection geometries armed with sophisticated equipments and strong sources of the order of 109 Bq or more. These experiments involve many corrections such as attenuation of x-rays in the target itself (self attenuation correction), attenuation in the window of the detector (window attenuation correction), solid angle correction, photopeak efficiency and total detection efficiency of the detector, etc. Estimation of intensity of radiations incident on the target is a difficult task in these methods. The incident intensity and the total x-ray fluorescence intensity generated in the target are the quantities, which determine the accuracy of the K x-ray fluorescence parameters. Recently Gudennavar et al. (2003a; 2003b) and Horakeri et al. (2011; 1998; 1997) have developed a simple method to measure K-shell fluorescence yields, production cross section and other parameters by adopting a 2geometrical configuration and employing weak radioactive sources. K x-ray fluorescence parameters are independent of angle of emission because K x-rays are emitted isotropically from the target atom. It was found that the method yields K x-ray fluorescence parameter values as accurate as any standard reflection geometry experiment. The simplicity of method helps one to utilize it to develop student laboratory experiments to train students in x-ray fluorescence field. Since the method requires weak sources, it is of great advantage to student laboratories for they do not need special permission to acquire sources and sources can be handled safely without any personal radiation hazards. However the validity of the target thickness criterion and the method needs to checked with other X-ray detectors such as CdZnTe, HPGe as their construction arrangements are different from NaI(Tl) detectors and for all the elements in the periodic table. In the present study, we have measured the K x-ray fluorescence parameters for the elements platinum and lead using HPGe detector spectrometer and 57Co excitation source. The results are compared with the theoretical, semi-empirical fitted and other experimental values. -

A RESEARCH ON THEMATIC PATTERNS SEEN IN INDIAN FILM DIRECTOR S.SHANKARS FILMS AND THE ROLE OF THE MAIN FILM CREW BEHIND THE SUCCESS OF HIS FILMS
Cinema has a huge amount of capacity to influence the audience. And it is because of this attribute that films either go on to become huge hits or a big disappointment. Everything depends on how the audience receives each film. Director S. Shankar has a track record of 100% success and this by any means, is a big achievement. Favourably for Shankar, even the critics have stayed away from dismissing his films from being just a commercial entertainer and for most of his work; there has been immense appreciation from their side. To contemplate more on the success story, there is a specific pattern observed in all his films and arguably, they have played a vital role in deciding the success. And these patterns are not just about the theme or the casting for which many other directors are known for. As a matter of fact, he does not follow the theory of developing a success combination with the actors. This is one such example of many other important yet unnoticed patterns followed by the director. The research paper attempts to identify and explain each pattern found in all or at least, in most of his films. The research also tries to identify the role of the film crew behind the success of Shankars films. -

The Experience of Flow among Kathak Dancers
Flow is a state of optimal experience proposed by Mihalyi Csikszentmihalyi (1975). Flow is the holistic experience that people feel when they act with total involvement and is characterized by intense engagement and enjoyment. The flow state has been explored diverse contexts such as art, music, theater, education and sports. The main contribution of flow studies to positive psychology involves adding value, purpose and enjoyment to subjective experience, thereby leading to a richer and intentional life existence. Dance is one such activity that increases enjoyment by integrating ones awareness with oneself and the surroundings. Kathak is a form of North Indian Classical dancing that lays emphasis on speed and rhythm. The present study aims to analyze the experience of flow in the context of Kathak performance. It also seeks to describe the experience of flow by linking challenge in the performance and skill of the dancer, the importance of feedback in performance and the unique competencies that enable a person to enter and maintain the state of flow. Seven Kathak dancers from Bangalore were interviewed in order to analyze how they experience flow. The research paradigm employed was phenomenology and in-depth interviews were used to gather data. Thematic analysis was the technique used in the study to generate themes. The findings of the study state that the dancers perceive Kathak as a challenging dance. The dancers perception of their skills influences their flow experience during performance. The Guru was seen to be an influential person whose feedback was considered valuable. The response from the audience and the dancers own self reflection were also important sources of feedback. The dancers had identified different purposes for performing Kathak. They were all motivated by their inner drives. The dancers also experienced a transformation from their personal selves when they were immersed in the dance. Self-confidence was seen to be an important facilitator of flow whereas anxiety was seen to be a major inhibitor. The results will be able to help dancers understand the importance of optimal experiences during dancing. An awareness of the what facilitates and inhibits flow can lead dancers to intentionally work on having clearer goals, better concentration, less self consciousness and raising the challenge level for themselves. The findings can be applied to dance therapy and also contributes to both research of dance and the relationship between dance and psychology in India. Keywords: Flow, experience, Kathak, challenge, feedback. -

EMPIRICALLY VALIDATING THE JOB CHARACTERISTICS MODEL IN THE HEALTHCARE SECTOR
The original model developed by Hackman & Oldham (1976, 1980) was tested for the healthcare sector in India following three staged model as proposed by the original authors. Out of several studies conducted so far using this model, majority of the studies had adopted two staged model. Stratified sampling technique was adopted to select the hospitals (equal number of hospitals selected from private, public and trust hospitals). Convenience sampling was adopted to administer the questionnaire (questionnaires were administered to the target sample from hospitals that gave permission under the three categories). Judgmental sampling method was adopted for deciding whom to administer the questionnaire. Inclusion and exclusion criteria included as employees should have worked for minimum 12 months in the present hospital to complete the questionnaire. 1550 questionnaires were distributed and 1244 fully completed questionnaires were compiled for analysis (80% response rate). Initially the model was tested using structural equation modeling. The study found that the job characteristics model as suggested by Oldham and Hackman (1976 and 1980) did not find good fit in the healthcare sector in India. Further the model was tested separately for nursing, paramedical and nonmedical category as they were the major stake holders in the healthcare sector. The result of the second model fit was also poor and found further fall in strength, which was tested based on the categorization ?? paramedical, nursing and nonmedical staff. Hence, the researcher found no scope of testing the structural equation model any further. Therefore, as the measurement model fails, the researcher intended to explore the dimensions using exploratory factor analysis. The result of the exploratory analysis indicated extracted 17 dimensions from 83 items. These 17-factors extracted from the exploratory factor were applicable to the Indian healthcare sector. This new tool needs to be tested in India for measuring the job characteristics, psychological states and personal outcome linkages. In this study we have analyzed the implications based on the results found. Some of the implications of the study were in the area of autonomy and feedback from the core job dimensions, experienced meaningfulness and knowledge of result from the critical psychological states and general satisfaction and specific satisfaction on pay from the personal outcome. We found very low pay satisfaction among the healthcare workers in India. It is suggested to the future scholars to experiment with the proposed new tool in the future research and explore the new model. A focused study interview could be conducted to find out the responses to job design using the qualitative approach and interviewing the most experienced professionals in hospitals. Two stage model could be tested in the Indian healthcare sector that is job characteristics and personal outcome, excluding critical psychological states. Key words: Job characteristics model, Healthcare, Paramedical, Nonmedical, Nurses.
