Correlational Study of Perceived Quality of Home Environment and Self-Concept Among Adolescents

Adolescence is a period which is marked by several physical, cognitive and socio-emotional developments, during this crucial phase how quality of home environment plays an important role in the development of self-concept to be explored by this study. A sample of 100 adolescents (50 males and 50 females) studying in class Xth, XIth and XIIth were selected from various schools of Aligarh Muslim University, Aligarh. For collecting data the research tools namely Home Environment Inventory by Dr. Karuna Shankar Misra (1983) and Self-concept scale by Dr. Mukta Rani Rastogi (1979) were used. Findings of the Pearson Product Moment Coefficient of Correlation revealed that for the development of positive self-concept among adolescents, there should be less or no use of rejection, control, deprivation of privileges and social isolation of home environment. Results also revealed that home environment nurturance and permissiveness showed significantly negative correlation and plays an important role in the development of components of self-concept that is beliefs and convictions and feelings of shame and guilt among adolescents. Further t-test shows significant gender difference in terms of the perception of different dimensions of home environment and self-concept. That is on both the dimensions males scored significantly higher in terms of mean score than female adolescents except feelings of shame and guilt. These findings suggest that there should be an intervention program arranged for enhancing relationship between parents and adolescents especially for females.

Uniform random sampling of planar graphs in linear time

AbstractThis article introduces new algorithms for the uniform random generation of labelled planar graphs. Its principles rely on Boltzmann samplers, as recently developed by Duchon, Flajolet, Louchard, and Schaeffer. It combines the Boltzmann framework, a suitable use of rejection, a new combinatorial bijection found by Fusy, Poulalhon, and Schaeffer, as well as a precise analytic description of the generating functions counting planar graphs, which was recently obtained by Giménez and Noy. This gives rise to an extremely efficient algorithm for the random generation of planar graphs. There is a preprocessing step of some fixed small cost; and the expected time complexity of generation is quadratic for exact‐size uniform sampling and linear for uniform approximate‐size sampling. This greatly improves on the best previously known time complexity for exact‐size uniform sampling of planar graphs with n vertices, which was a little over O(n7). © 2009 Wiley Periodicals, Inc.

Quadratic exact-size and linear approximate-size random generation of planar graphs

This extended abstract introduces a new algorithm for the random generation of labelled planar graphs. Its principles rely on Boltzmann samplers as recently developed by Duchon, Flajolet, Louchard, and Schaeffer. It combines the Boltzmann framework, a judicious use of rejection, a new combinatorial bijection found by Fusy, Poulalhon and Schaeffer, as well as a precise analytic description of the generating functions counting planar graphs, which was recently obtained by Giménez and Noy. This gives rise to an extremely efficient algorithm for the random generation of planar graphs. There is a preprocessing step of some fixed small cost. Then, for each generation, the time complexity is quadratic for exact-size uniform sampling and linear for approximate-size sampling. This greatly improves on the best previously known time complexity for exact-size uniform sampling of planar graphs with $n$ vertices, which was a little over $\mathcal{O}(n^7)$.

Jealous conflict in dating couples.

80 steadily dating couples were assigned by sex to jealous or nonjealous role-playing conditions in which one partner was asked to assume a distancing role while the other was asked to overcome the distance and try to establish closeness with the partner. Using Raush, et al.'s (1974) method of studying interpersonal conflict through improvisation, it was found that persons in distant roles and experiencing jealousy used significantly more rejection and coercion, especially guilt-induction, than did subjects who experienced distance for nonjealous reasons. No sex differences were noted with regard to the use of rejection and coercion. However, men selected their issues of jealousy as sexual while women selected jealous issues which involved a loss of time and attention.
