Some Insights into Procedures and Practices to Acquire the Right Talent

HRM views talent as Human Resource Capital .The focus of talent management is to attract best talent and convert them into effective work force. The future is Talent Analytics; Human Resource Analytics is the application of sophisticated data mining, and business analytics (BA) techniques to human resources (HR) data. The descriptive study based on observation and interviews was conducted in Dr.Reddy’s an emerging Indian Pharma major in global space. The recruitment philosophy of Dr.Reddy’s is embedded in the talent acquisition process and is oriented to acquire the talent with highest commitment to fulfill the organization’s core purpose. The boomerang policy, integrated HRIS system etc., enable talent analytics in the Organization. The talent acquisition system is based on Role-Designation matrix.

Detection of F-region electron density irregularities using incoherent-scatter radar

Thesis (M.S.) University of Alaska Fairbanks, 2014.Incoherent-scatter radar data from Poker Flat, Alaska has been used to determine size distributions of electron density structures in the evening time sector of the auroral zone. At high latitudes ionospheric plasma typically moves east-west with speeds of several hundred meters per second. Density irregularities that rapidly move through the radar beam are therefore observed as time-varying power fluctuations. The new phased array radar used for this study has been operated with several antenna directions with successive pulses transmitted in each direction. It is therefore possible to observe plasma Doppler velocities in multiple directions and determine the vector direction of the plasma motion. This near-simultaneous observation of the plasma velocity in conjunction with the electron density height profile data enable a new technique to determine the scale sizes of electron density fluctuations that move horizontally through the radar beam. The study focuses on the collision-less F-region ionosphere where the plasma drift is approximately constant with altitude. The experimental technique limits the range of scale sizes that may be studied to relatively large-scale sizes (i.e. greater than few tens of km). Results show that during magnetically disturbed conditions (Kp ≥ 4) when westward plasma velocities are relatively high (500-1000 m/s) the scale sizes of irregularities (often called plasma blobs) are in the range of 100-300 km and predominantly originate from the polar cap and are transported over long distances (~1000 km) due to the long chemical recombination times (30-90 minutes). Some irregularities are caused by local auroral particle precipitation and have been identified with associated electron temperature enhancements. For cases of low magnetic activity (Kp ≤ 1), when the radar is located in a region of low plasma velocities (100-500 m/s) well south of the auroral oval (essentially a mid-latitude type ionosphere), the density distribution is always biased strongly toward small-scale sizes (less than 50 km).Chapter 1.

CYTOTOXICITY OF CHLOROFORM EXTRACT OF WALTHERIA INDICA L. LEAF

India has the richest bio-resource of medicinal plants that have long life history of application in the treatment of diseases from the ancient times. The drugs that are obtained from the medicinal plants have been well favored by the people because of its treatment efficacy which is less when compared to the modern drugs but causes lesser side effects. This advantage lead the research field of pharmacy to discovery of the active constituents that are responsible for causing the pharmacological action on human body. The active constituents from the medicinal plants are more effective and do not cause any side effects. This study has been made to investigate the cytotoxic effect of chloroform extracts of Waltheria indica leaves on cervical cancer cells. Extracts were studied for their toxicity by MTT assay, Trypan blue dye exclusion assay, cell viability was studied by LDH assay and Apoptosis was measured by DNA fragmentation assay. The extract screened for phytochemical analysis was found to contain bioactive compounds like carbohydrates, glycosides, saponins, phenolic compound and triterpenoids were present..The cytotoxicity study clearly showed the dose dependent cytotoxic effect of extract in HeLa cell line with an CTC50 of 103.33±5.77 for MTT assay and 90.00 for Trypan blue dye exclusion assay. The LDH leakage was observed in a dose dependent manner with an LDH IU/mg of total protein of 36.18. The dying cells showed characteristics of apoptosis such as, DNA fragmentation. The data in the present study clearly demonstrated cytotoxic effects of extracts on human cervical cancer cells

Ab Initio Investigation of Intramolecular Charge Transfer States in DMABN by Calculation of Excited State X-ray Absorption Spectra

Dual fluorescence in 4-(dimethylamino)benzonitrile (DMABN) and its derivatives in polar solvents has been studied extensively for the past several decades. An intramolecular charge transfer (ICT) minimum on the excited state potential energy surface, in addition to the localized low-energy (LE) minimum, has been proposed as a mechanism for this dual fluorescence, with large geometric relaxation and molecular orbital reorganization a key feature of the ICT pathway. Herein, we have used both equation-of-motion coupled-cluster with single and double excitations (EOM-CCSD) and time-dependent density functional (TDDFT) methods to investigate the landscape of excited state potential energy surfaces across a number of geometric conformations proposed as ICT structures. In order to correlate these geometries and valence excited states in terms of potential experimental observables, we have calculated the nitrogen K-edge ground and excited state absorption spectra for each of the predicted "signpost" structures, and identified several key spectral features which could be used to interpret a future time-resolved x-ray absorption experiment

Contextual Reference of Gandhian Philosophy in Human Resources Management Practices

India is a land of philosophers; Gandhi is a reformer and a modern philosopher who invented tools to inspire the masses. These tools find relevance in present day, Gandhian Philosophy is based on the four pillars; Truth, Non-Violence or Ahimsa, Self-Respect and Satyagraha. He practiced and preached the life of austerity, humbleness and truth. His philosophy of simple living and high thinking attracted the peasants, humbled the mighty and the rich. The present paper analyses the application of the principles in the present context with respect to human resources practices. The present global context requires inspirational leadership style with appropriate strategy; Gandhiji is the best strategist with follower centric approach. The human resource management practices were linked with human factor theory and defined as a bundle of practices. The strike as a right, collective bargaining, arbitration and self-introspection were some of his contributions

MACHINE LEARNING BASED MEDICAL INFORMATION RETRIEVAL SYSTEMS

As many fields progress with the assistance of cognitive computing, the field of health care is also adapting, providing many benefits to all users. However, advancements in this area are hindered by several challenges such as the void between user queries and the knowledge base, query mismatches, and range of domain knowledge in users. In this research, we explore existing methodologies as well as look into existing real-life applications that are used in the medical field today. We also look into specific challenges and techniques that can be used to overcome these barriers, specifically related to cognitive computing in the medical domain. Future information retrieval (IR) models that can be tailored specifically for medically intensive applications which can handle large amounts of data are explored as well. The purpose of this work is to give the reader an in-depth understanding of artificial intelligence being used in the medical field today, as well as future possibilities in the domain. The models and techniques designed and discussed in this research can help provide a framework, or starting point for those interested in effectively developing, maintaining, and using these models to help improve the quality of health-care. Furthermore, we explore the development process of such a model and discuss the steps including data collection, processing, model creation, and also improvement
