The assessment of carbon storage potential has been difficult due to the lack of information on biomass compartmentation and carbon allocation in different species. For most of the species used for afforestation/reforestation, only the above ground biomass potentials are known but to have a picture of carbon storage potential of species, the below ground biomass pattern are equally important. This study was aimed to measure the biomass partitioning and the actual carbon allocation in different components of agroforestry tree species. The biomass accumulation through stem was highest in Acrocarpus fraxinifolius (22.35 kg), which was statistically at par with Populus deltoides (18.92 kg) and Eucalyptus tereticornis (16.16 kg). There was no statistical difference in below-ground biomass of different tree species. The highest tree stem carbon storage at the plantation level was found in Acrocarpus fraxinifolius (6.05 t ha-1), while the lowest was in Syzygium cumini (0.73 t ha-1). The mean carbon storage in tree ischolar_mains was 1.55 t ha-1, while the mean stem carbon storage was 2.70 t ha-1. It was observed that the carbon content of biomass components had relatively little influence on total carbon storage compared to the relative biomass in each tree components. Stem alone though was the largest store house of carbon but litter and ischolar_mains in the short rotation tree species play a major role in carbon sequestration in the soil reservoir. The fate of stem carbon depends upon its end use and needs locking up in post harvest products for longer period.Keywords

The increasing level ot green house gases in general and carbon dioxide in particular has raised concerns about the vulnerability of human, animal and plant life. Forests though serve as source and sink of the CO2 there is need to synthesize the impact of climate change on forests and the role of forests in global carbon cycle. Soil accounts for a major organic carbon pool, which needs to be quantified in tree based systems. At a rotation of seven years, poplar timber carbon content was 23.57t/ha and an equal amount was contributed by ischolar_mains, leaves and tree bark. The contribution of branches was 24 per cent of the total 62,48t poplar biomass (carbon storage) in seven years. Soil organic carbon increase was also substantial under tree-crop interface than sole wheat cultivation. The annual biomass in agroforestry intervention not only accumulated sixty per cent more carbon but a major portion of carbon is stored over a longer period than the sole crop.Keywords

This paper deals With the comparative study of teacher effectiveness of secondary school teachers in relation to their demographic variables i.e. gender, type of school and locality. Effectiveness of the process of education is rightly seen in the effectiveness of the teachers. Only effective teachers can materialize plans and policies in the classroom at the grass-ischolar_main level. The objectives were to compare the teaching effectiveness of male and female secondary school teachers, to compare the teaching effectiveness of the teachers working in government and private secondary schools, to compare the teaching effectiveness of the teachers belonging to urban and rural secondary schools. Thus, data was collected from 128 secondary school teachers at Rohtak District in Haryana through survey method by using standardized tool Teacher Effectiveness Scale (TES) by P. Kumar and D.N Mutha. In order to make comparison between Male/Female, Govt./Private, Urban/Rural teachers, various statistical techniques like Means, Std. Deviation, t-test were employed. Results showed that there existed no significant difference in teacher effectiveness on gender, type of school and locality basis.Keywords

The present paper describes the relationship between teacher effectiveness and oecupational stress among secondary school teachers. It is an established fact that the performance of teacher mainly depends upon his psychological state of mind. As occupational stress affects the physical and psychological well being of the teacher; it is definitely influences his efficiency and performance. The objectives of the study were to find the relationship between teacher effectiveness and occupational stress and predicting teacher effectiveness on the basis of occupational stress. In order to find the relationship between the two variables, the data was collected from 128 secondary school teachers at Rohtak District in Haryana through survey method by using standardized tools like the teacher effectiveness scale by Kumar and Mutha and The Occupational Stress Index by A.K. Snrivastva. The findings made it clear that there existed a negative relationship between teacher effectiveness and occupational stress. Out of 12 dimensions of occupational stress, five factors that emerged as the predictors of teacher effectiveness were intrinsic impoverishment, low status, powerlessness, under participation, responsibility for persons which are causing 34.3% of the variance in teacher effectiveness.Full Text

With 1.44 billion monthly active users in early 2018], Facebook is the leading social networking site in most countries worldwide. For younger generations, Facebook is not only a tool or an application on the Internet but also a ubiquitous level of reality, where the boundaries between online and off-line actions are increasingly blurre. Especially for users of the Facebook mobile client, checking status updates and interacting with Facebook friends have become part of their daily routines. Facebook is an ideal environment for studying human behavior. Every click, like, friend acceptance (or rejection) is tracked for millions of people every day. Facebook's value as a "petri dish for the social sciences."Brands spend billions of dollars a year on elaborate efforts to establish and maintain a social media presence. Facebook is the preferred platform: 80% of Fortune 500 companies have active Facebook pages. Each day enormous amounts of brand-generated content—articles, photos, videos, and so on—appear on those pages and on other social media platforms, all designed to entice people to follow, engage with, and buy from brands. Marketers often justify these investments by arguing that attracting social media followers and increasing their exposure to a brand will ultimately increase sales. According to this logic, recruits who socially endorse a brand by, for example, liking it on Facebook will spend more money than they otherwise would, and their endorsements will cause their friends (and friends of friends) to shop—creating a cascade of new business. At first glance the evidence seems to support this rationale: Many brands have discovered that customers who interact with them on social media do spend more money than other customers. A recent influential study by Facebook found that compared with the general population, people who liked Starbucks’s Facebook page or who had a Facebook friend who liked the page spent 8% more and transacted 11% more frequently over the course of a month.
Merely liking a brand on Facebook doesn’t change behavior or increase purchasing. But that study and others like it contain a fatal logical flaw: They confuse cause and consequence. It’s possible that getting people to follow a brand on social media makes them buy more. But it’s also possible that those who already have positive feelings toward a brand are more likely to follow it in the first place, and that’s why they spend more than non followers.
