Optical, NLO, dielectric, thermal and hardness properties of mono valent metal ion (Ag+, Li+ and Na+) doped KAP crystals
Crystals of potassium hydrogen phthalate (KAP), a semi-organic compound, have been grown by slow evaporation method at room temperature from aqueous solution in the presence of mono valent metal ionic impurities Ag+, Li+ and Na+. Elemental analysis by inductively coupled plasma optical emission spectroscopy (ICP-OES) proves the incorporation of these impurities into the grown crystals. Powder X-ray diffraction studies confirmed the phase formation and metal ions doping into KAP crystals. Thermo gravimetric analysis (TGA) show the onset decomposition temperatures to be 255, 258, 238 and 272°C for pure and Ag+, Li+ and Na+ doped KAP crystals respectively. Microhardness studies revealed that Na-KAP crystals have higher hardness values than all the doped crystal. All the crystal exhibited the second harmonic generation (SHG) conversion efficiency. The grown crystals were also subjected to Fourier transform infrared (FTIR) spectroscopy, UV-Vis spectroscopy studies and dielectric studies. Among the three investigated metal ion impurities, Na+ ion seem to have positive influence on the growth, mechanical, thermal, dielectric and SHG characteristics of KAP which makes it suitable for limited level of applications.

Organizational Commitment: An Empirical Study
In the present era of globalization with increased opportunities and easy and free movement of workforce, companies are striving hard to retain their employees to get the best out of them. It is considered that a committed workforce is an asset to the organization. What are the factors which influence employees’ commitment towards organization is a much debated aspect in the management field. A good number of literatures on organizational commitment opine that organizational commitment is a psychological attachment of the members of an organization including a sense of job involvement, loyalty and belief in the values of the organization. On the other hand it indicates that a committed employee is one who accepts the organizational goals and willing to exert effort on behalf of the organization. An employee, who is affectively committed, strongly identifies with the goals of the organization and desires to remain the part of the organization. This study makes an effort to analyse the relationship between the behavioral aspects of the employees such as performance, loyalty, satisfaction with the organizational commitment as well as the relationship between the behavioral aspects with the personal attributes such as age, gender, position and length of service. The study reveals that there is a strong positive relation between the organizational commitment and performance, loyalty and satisfaction while there is no significant relationship between the behavioral aspects and the personal attributes.

Problems and Prospects of In-Service Teacher Training-A Review
In-service training of teaches is a systematic process and wide infrastructure that requires extensive communication to execute any program in order to ensure maximum involvement of all those who are associated with educational enterprise, one or the other way like teachers, administrators, curriculum-developers, research workers, teacher trainers, specialists, etc. In-service training programs actually provide an opportunity to those who are trained but in experienced. This type of training facilitates professional learning and helps teachers to abreast themselves with the upcoming knowledge, educational developments and innovations but unfortunately there are numerous problems that interrupt when these programs are intended to commence. So in order to overcome expected problem, a model has been suggested in this article that will conducive for resolving problems of in-service teacher training and it will provide an insight in order to certify successful and more beneficial planning of such programs. Improvement in any education system can only be made when teachers are given upmost priority and their in-service training is considered mandatory in order to meet new challenges. In brief to deal with modern challenges, teachers’ professional development or in service training is imperative, as said by John Cotton Dana: “Who dares to teach must never cease to learn”.

Quantum chemical calculations on oxygen monofluoride (OF) and its protonated analogues: Comparison of methods
Quantum chemical calculations offer the real promise of being able to complement experiment as a means to uncover and explore new areas in chemistry. One of such is its use in the determination of molecular structure, kinetics and reactivity. This work seeks to investigate the molecular properties of Oxygen monofluoride (OF) and its two possible protonated analogues (HOF+ and HFO+). Quantum chemical methods; Hartree fock (HF), Becke-3-Lee-Yang-Parr (B3LYP), Moller-Plesset second order (MP2), Coupled Cluster method (CCSD) and Gaussian 04 method (G4) with varying basis sets were employed in the determination of the parameters (Dipole moment, bond distance, IR frequency, zero point vibrational energy, and rotational constants) reported for the three molecular species studied in this work. Bond angle was reported for the two protonated analogues (HOF+ and HFO+). From the results as compared to the experimental values, B3LYP/6-311++G** method proves itself as the best method in the optimization and frequencies calculations of the OF, HOF+ and HFO+ because it gives better accuracy in most of the calculated parameters and the MP2 method also give relative accuracy in some of the calculated parameters of OF and its protonated analogues, HOF+ and HFO+. The optimized geometry shows the OF molecule to be linear while the protonated analogues were non-linear.

Re- thinking Carl Jung’s psycho-religious epistemology as a viable epistemic complement for the 21st century world
Knowledge inspires human behaviours and actions and also influences the nature and directions of development. The study of knowledge [sources and contents] technically known as epistemology is traditionally rooted in philosophy. However, this branch of philosophy being bedeviled with much controversy has shredded scholars into various groups and created relationship impasse between them. Consequently, modern direction of development became adversely affected with its emphasis on the material aspect of mankind and nature. This method reduces the spiritual/ metaphysical aspect of mankind and nature to state of triviality in modern development. Thus we suffer personality crisis as we live without knowledge of ourselves and our world. Therefore, this paper betook itself to explore a complementary epistemology based on the spiritual aspect of human nature. This model is couched in Carl Jung’s Psycho-Religious ideality. The paper discovers through Histo-religious and philosophical investigations that the centerpiece of Jung’s epistemology/metaphysics hinges on ‘Collective unconscious. Jung’s epistemology oscillates between psychology, sciences, philosophy, various religious traditions and mythology and he uses the composite knowledge of these disciplines to guide humanity in her desire for holistic knowledge. Against this backdrop, this paper concludes that if Jung’s Psycho-Religious epistemology is explored as a complementary epistemic system for the 21st Century, then humanity would have attained a holistic knowledge of herself and nature and this will reduce the violation of all lives and in consequence facilitates a balanced development.

Role of remittances and banking sector development in Nepal
The paper investigates the interaction among foreign remittance, banking sector development and GDP in four South Asian nations that export huge pools of labour abroad. Multivariate Granger causality tests, based on error correction models, are employed with data spanning from 1990 to 2010. A key finding of the paper is that remittances and banking sector development influence per capita income in all four South Asian nations. In addition, interactions among the variables are also examined in a panel setting. As in individual country analyses, both remittance and banking sector development have positive and significant influences on the national income of Nepal. On the other hand, neither domestic products nor advancement in banking sector have significant impact on the remittance flows. This is new findings of the linkage between remittances and economic development, which may also be evident for countries exporting labour pools. Remittance as a major source of foreign currency to the developing nation has become a substantial component of making current account surplus in the balance of payments. It is argued that many workers from Nepal going abroad for employment are no doubt young, energetic, laborious and enthusiastic. They do hard work for earning large remittance income to support their families. However, the downside of remittances reflects the view that remaining young generation for long time outside without family may increase their vulnerability and ultimately it will have a tendency to leave their homeland. Thus, in order to recover the loss of economically active labor force to the domestic economy, they should be encouraged to come back again with skilled knowledge for utilizing their savings and working experience for development to the productive areas in accordance with the priority of the national development plans.
