Study of Personality Factors and Family Problems as Determinant of Mental Health amongst College Students[]

While all students face a range of mental health concerns, it is important to consider undergraduate students as a distinct group. Because these students face a unique set of circumstances which play an intricate role in the manifestation of mental health problems. Thus the aim of the present study was to determine the effect of different personality factors and family problems on mental health of college students. The participants were 225 (age range 18-21 years) students, randomly taken from Aligarh Muslim University, Aligarh and Albarkaat Public School of Aligarh. A set of questionnaires namely NEO-Five Factor personality Inventory developed by Costa & McCrae (1992), Youth Problem Inventory used for measuring family problems developed by Sandhya Sharma (1979) and Mental Health Inventory (Jagdish & Srivastava, 1983) were used. Results of multiple regression analysis (step-wise) revealed that amongst all personality factors extraversion found to be significant predictor for positive self-evaluation; openness emerged as a significant predictor for perception of reality, agreeableness for integration of personality. Similarly, extraversion and conscientiousness significantly predict environmental competence dimension of mental health among students. However, family problems predict only two dimensions of mental health i.e. positive self-evaluation and environmental competence. Furthermore findings of t-test revealed that both male and female group of students differ significantly on extraversion, openness and agreeableness factors of personality. They also significantly differ on total mental health including integration of personality and environmental competence dimensions of mental health. But only on family problems no gender difference found. Present findings can be concluded as early detection for indications of mental health problems and understanding factors such as family problems and different factors of personality among students would promote better understanding of mental health in future.

Development of Anti-theft System For Wireless Sensor Networks in Cloud Environment[]

A new anti-theft system is designed using WSN in cloud environment, where broad ranges of vital applications that acquire and process information from the corporeal world are in the extensive need of Wireless sensor networks. However, the limited resources of a sensor, especially limited battery life, limited bandwidth and limited processing power, are the main challenges for deploying and operating WSNs. This paper proposes an architecture based on cloud computing for wireless sensor network in anti-theft system, where we can easily get know of the devices or the things that are missing in the prescribed region or place or in a company.

Parent adolescent perception of Family environment in defence officers’ families in India[]

Families in defence services experience unique environment and challenges not generally found in other work environments. These are likely to influence the family environment and its perception by parents and adolescents. Research has shown that discrepancy in parent adolescent perception has marked influence on adolescent development and adjustment. The present study was thus carried out on 240 defence officers’ families to understand parent adolescent perception of family environment and to find out differences in their perception if any. Results of the present study indicate that despite several service related stressors, defence adolescents and their parents in all the three wings of services have a favorable perception of their family environment. There are no significant inter services differences in the perception of majority of the dimensions of family environment. Both parents and adolescents in the defence families perceive the dimensions of Expressiveness and cohesion high and extremely high, Competitive framework ,moral orientation and organization high average and Independence and recreational orientation average. Significant difference in perception exists only in dimensions of moral orientation and competitive framework, with perception of adolescents being better than that of their parents.

Solvent Effect on the Third Order nonlinearity of Oxazine Dye Doped PMMA Films by Using Z-Scan Techniques[]

This experimental work is a study for solvents effect on the nonlinear optical properties of oxazine dyes doped films in PMMA at concentration of 10-5 M in three solvents (Trichloroethan,Chloroform,THF) by using a high sensitive method known as Z-Scan technique.

The first part was done using a closed-aperture placed in front of the detector to measure the nonlinear refractive index and in the second part; the aperture in front the detector was removed (open aperture) to measure the nonlinear absorption coefficient and then to measure third order susceptibility . The nonlinear refractive index is found to be of the order of 10-6 cm2/W. The magnitude of third order susceptibility is of the order of 10-9 cm/watt. The nonlinear absorption coefficient has also been determined.


Textile industries are vital components of improving the economy of a country. Neverthless they contribute a major propotion to the category of environmental pollutants. Coloured dyes were collected from select outlets of Madurai city and the native actinomycete was isolated . The dye decolorisation capability of the native isolate was tested against a standard MTCC strain of Phanerochate chrysosporium. The declourisation percentage of Streptomyces sp decreased as the amount of dye effluent added to the media increased. Red dye reported 55% for 1ml of the dye effluent and green dye reported 60%. This was reduced to 30% when 25ml of dye effluent was added. The standard MTCC strain reported 79% and 42% respectively for the same amount . The same trend was observed for the protein content also.

Auteur Theory and its implications []

In film criticism, auteur theory holds that a director's film reflects the director's personal creative vision, as if they were the primary "auteur" (the French word for "author"). In spite of—and sometimes even because of—the production of the film as part of an industrial process, the auteur's creative voice is distinct enough to shine through all kinds of studio interference and through the collective process. In law, the film is treated as a work of art, and the auteur, as the creator of the film, is the original copyright holder. Under European Union law, the film director is considered the author or one of the authors of a film, largely as a result of the influence of auteur theory. Auteur theory has influenced film criticism since 1954, when it was advocated by film director and critic Francois Truffaut. This method of film analysis was originally associated with the French New Wave and the film critics who wrote for the French film review periodical Cahiers du Cinéma. Auteur theory was developed a few years later in the United States through the writings of The Village Voice critic Andrew Sarris. Sarris used auteur theory as a way to further the analysis of what defines serious work through the study of respected directors and their films.

The Impact of Fair Value Measurement on Financial Instrument of Firms in Nigeria[]

This study assessed the impact of fair value measurement on financial instrument of firms in Nigeria. The objective of this study is to determine the extent to which fair value measurement can be applied with precision in the assessment of a firm’s financial position and to determine the possibility of measurement errors in financial instrument measured on Fair Value.The method of data collection used in this study was field survey method involving the use of questionnaire administered to 188 samples. The method of data analysis was the Kruskal-Wallis rank sum test statistic. From the result of the analysis it was observed that the implementation of Fair Value measurements gives sufficient precision in assessing firm’s financial position and earning potential since majority of the respondents agreed with a mean rank (mean rank=35.38) and a corresponding Chi-Square test statistic value of 33.27 and a p-value of 0.00 which falls on the rejection region of the hypothesis. Also observed was that the possibility of measurement errors in financial instrument measured on Fair Value basis was high since majority of the respondents agreed with a mean rank (mean rank= 24.50) and a corresponding Chi-Square test statistic value of 20.13 and a p-value of 0.00 which falls on the rejection region of the hypothesis. Hence, we conclude that Fair value is the best reflection of the expected future cash flow as it predicts the ability of the entity to take advantage of opportunities or to react to adverse situations. We recommend that for fair value accounting to be beneficial in Nigeria there should be vigorous policing and enforcement of punitive actions against insider abuse and other forms of market manipulation.

We have studied the equilibrium lattice constants and energy band structures of NbC and NbN using the full-potential linearized augmented-plane-wave (FP-LAPW) method within the framework of the density functional theory (DFT). The calculation has been performed by using the generalized gradient approximation (GGA) for the exchange and correlation potential. Computations have been performed using the WIEN2k codes. The result obtained is reasonable and compares well with the experimental data and other calculations.


Public support of self-employment has a long tradition in India. The social market model perceives entrepreneurs as important actors to adopt the economy to changing markets, promote innovation and sustain competitiveness. Many programs have therefore been developed over the decades to support business foundations through consulting services and financial resources, research and development co-operations, preferential treatment in labor and tax regulation etc. SMEs in general and craft - related businesses in particular are a special concern of economic policies in India.The promotion of business foundations for unemployed persons is based on former positive experience with such programs not only the scale of the programs was extended but the target group was defined much wider: small-scale businesses - even self-employment without employees - were promoted. The former focus on crafts and trade related businesses shifted towards services in general.

Effect of Integration of Fly Ash with Fertilizers and FYM on Nutrient Availability, Yield and Nutrient Uptake of Rice in Inceptisols of Assam, India.[]

A field experiments was conducted in kharif season 2012 at Instructional Cum Research Farm of Assam Agricultural University, Jorhat on Inceptisols to study the effect of application of fly ash alone and in combination with recommended dose of fertilizers and farm yard manure on yield and uptake of rice, physicochemical properties and nutrient availability of the soil. The results indicated that the treatments which received fly ash @ 5 and 15 t ha-1 recorded a yield increase of 23.3% and 32.4%, respectively over absolute control. The highest rice yield (34.1 t ha-1) was recorded in treatment 50% RDF + FYM 5 t ha-1 + FA 15 t ha-1. On the other hand, fly ash applied @ 5 t ha-1 in combination with RDF 50% + FYM 5 t ha-1 produced 40.1% more yield over absolute control. The significant increase in the uptake indicated that fly ash could serve as a source of plant nutrients. Under integrated plant nutrient supply system with fly ash, its effect was well pronounced. The addition of fly ash resulted in significant increase in pH, EC, organic-C, CEC and available nutrient in the post harvest soil.
