Vaccination through leishmanization with live Leishmania major has been used successfully but is no longer practiced because it resulted in occasional skin lesions. A second generation leishmanization is described here using a CRISPR genome edited L. major strain (LmCen−/−). Notably, LmCen−/− is a genetically engineered centrin gene knock-out mutant strain that is antibiotic resistant marker free and does not have detectable off-target mutations. Mice immunized with LmCen−/− have no visible lesions following challenge with L. major-infected sand flies, while non-immunized animals develop large and progressive lesions with a 2-log fold higher parasite burden. LmCen−/− immunization results in protection and an immune response comparable to leishmanization. LmCen−/− is safe since it is unable to cause disease in immunocompromised mice, induces robust host protection against v...

The scales are standardized under local settings and most of the Indian researchers utilize these national level scales for the assessment of scientific attitudes. In this work 23 such Indian scales are reviewed over their psychometric properties. The study showed that most of the scales lack theoretical foundations and psychometric evidences. A scale by Bajwa & Mahajan (2012) is selected over its appropriate theoretical background. But many of the items are inappropriate, they failed in the validity checkup through 11-experts and 218-student tryout. Thus, a new scale is developed by retaining some of the items of the scale. The developed scale is standardized and validated through 200, 312 and 641 student tryouts. All statements in the developed scale show high item to scale correlation values. Exploratory factor analysis (EFA) confirms the five sub-scales namely rationality, curiosity, open-mindedness, aversion to superstition and confidence in scientific method. The Cronbach's alpha coefficient value of the scale is high i.e. 0.79. The scale establishes its content, construct, concurrent and discriminant validities. This study results in to a valid scientific attitude scale that can be utilized in further researches.

The Present study was carried-out on the sample of 200 students comprising of 100 drop-outs and 100 stay-ins selected through stratified random sampling method from 80 primary schools of Poonch district. In order to measure the caste, occupation and educational background of drop-outs and stay-ins a standardized Socio-Economic status scale (SES) was used to collect the required information. The collected data was tabulated by using percentage method. The study revealed that majority of students who dropped-out from the schools before completing their elementary education belonged to low caste, occupation and educational background as compared to their stay-ins counterpart. In the end of this paper, some suggestive measures have been put forward by the authors.

And a te cher plays vital roles in not only cognitive but noncognitive developments among the students as well. The presen t work was aimed at finding the impact of teaching effectiveness (TE) and SAs over physics achievement (PA) of senior sec ndary students. The study utilized 309 senior seco ndary students in Shahjahanpur district of Uttar Pradesh, India. The results show good significant correlations among TE & SA and TE & PA, but a weak correlation between SA & PA. And no gendered responses were reported among students SAs and experienced physics TE. While the multiple stepwise regression analysis does not est abli h SAs as a predictive variable of PA and only TE was found to have 18.3% of the total varia...

But besides being one of the most important subjects it remains one of the most difficult subjects at school curriculum. The difficulty of a subject may be due to several institutional, psychological, personal, familial, environmental or teacher related factors which effects a student's achievement in any subject. Among these factors, personal factors such as study habits and self-concept play a vital role and are great predicators of a student's achievement in any subject. As study habits include the habitual manners a student plans his study and self-concept is one's own perception about him-self, both could be good predictors of a student's achievement in subject physics as well. The present study is an attempt to study the relation of physics achievement with study habits and self-concept of senior secondary school stud...

The present study aims to study the significant predictors in mathematics achievements among adolescents. Descriptive survey method was used as a research design for the study. The target population of the study was the students studying in senior secondary schools of Moradabad city in Uttar Pradesh (India). A sample of 123 students was randomly selected out of 5 senior secondary C.B.S.E. schools out of which 66 were males and 57 females. The study revealed that Intelligence emerged as the most significant predictor in mathematics achievement among adolescents. This is in consistent to previous researches conducted by Das (1986), Patel (1997), Kasat (1991), Abdulmajeed (1992) and Fernandez (2011), who reported positive relationship between the intelligence and mathematics achievement.

Fast urbanization, rapid industrialisation and advancement in technology have lead to the heavy depletion of natural resources deteriorating man's physical, mental and social health. In order to bring back same balance, environmental awareness regarding environmental issues and its sensitivity among population is necessary. Education is a powerful medium for attending the environmental problems, as it reaches to large parts of population & the perception and attitude that a child forms towards environment is likely to be carried out throughout his life. In present empirical work the comparative analysis of gender (male and female), place of residence (urban and rural) and subject background (science and non science) have been made with regard to the environmental awareness level on a sample of 106 undergraduate students of Aligarh. Analysis of the results showed significant differences between all the compared groups ie male & female, Science & non science and urban & rural. Results are discussed in the light of previous researches and suggestions have also been put forward to sensitize the students towards achieving an ecologically sustainable society.

In order to uplift them through different policies and plans Government of India in consultation with Jammu and Kashmir Government had kept them in reserved (SC, ST, OBC, RBA, ALC) & non-reserved (General/Open) category. Does students belonging to reserved & non-reserved category differ in terms of their academic anxiety has motivated the researcher to approach this problem. Aim: The main objectives of the study were to find out the relationship between academic anxiety, intelligence and study habits of total sample groups and subgroups. To explore category (reserved & non-reserved) and gender (male & female) differences in academic anxiety, intelligence and study habits of total sample groups and subgroups and to find out significance of difference in the mean scores of academic anxiety among all comparative groups under study. Method: A sample of 537 students including 329 reserved categories and 208 non-reserved category students aged between 14-18 years were selected through stratified random sampling technique. Data was collected by administering self-constructed Academic Anxiety Scale bearing dependable validity and reliability, Standardised Group Test of Intelligence by Ahuja (2009) and Study Habits Inventory by Lajwanti, Chandel, & Paliwal. (2013). Results: Academic anxiety was correlated with intelligence and study habits of total sample groups and subgroups under study. On an average students belonging to non-reserved category were higher in academic anxiety scores but were possessing better study habits than reserved categories students. In terms of academic anxiety's mean score differences among all comparative groups under study, only reserved categories females were suffering more from academic anxiety than reserved categories males sample. Conclusion: More research on psychological health of reserved & non-reserved categories students especially in their socio-cultural and political context is needed so as to evolve effective and practical preventive measures.

The purpose of all academic and non academic activities of the schools is basically to enhance the academic achievement of students. It is influenced by a number of personal, institutional factors and social and economic factors. Personal factors are very important in influencing the academic achievement. Therefore, the present study has analyzed two personal factors i.e study habit and achievement motivation to see its influence on academic achievement. The study has also taken into consideration community (Muslims and non Muslims) and gender variables. The present study was carried out on sample of 278 adolescents studying in class X of Aligarh schools. The study has revealed mixed results which have been presented and interpreted along with some suggestive measures.
