Adjacency Matrix Based Energy Efficient Scheduling using S-MAC Protocol in Wireless Sensor Networks

Communication is the main motive in any Networks whether it is Wireless Sensor Network, Ad-Hoc networks, Mobile Networks, Wired Networks, Local Area Network, Metropolitan Area Network, Wireless Area Network etc, hence it must be energy efficient. The main parameters for energy efficient communication are maximizing network lifetime, saving energy at the different nodes, sending the packets in minimum time delay, higher throughput etc. This paper focuses mainly on the energy efficient communication with the help of Adjacency Matrix in the Wireless Sensor Networks. The energy efficient scheduling can be done by putting the idle node in to sleep node so energy at the idle node can be saved. The proposed model in this paper first forms the adjacency matrix and broadcasts the information about the total number of existing nodes with depths to the other nodes in the same cluster from controller node. When every node receives the node information about the other nodes for same cluster they communicate based on the shortest depths and schedules the idle node in to sleep mode for a specific time threshold so energy at the idle nodes can be saved.Comment: 20 pages, 2 figures, 14 tables, 5 equations, International Journal of Computer Networks & Communications (IJCNC),March 2012, Volume 4, No. 2, March 201

An Analysis of Select Models of Rural Education in Developing Nations and Their Possible Applicability in India

This study conceptually analyses select rural education models which have been implemented successfully in various developing countries. The models chosen for the study possess distinct features- administrative, financial, academic as well as ideological- which have led them to achieve better qualitative standards in education for rural and underprivileged children. The paper points out those features which resonate the most with the Indian socio-economic scenario and discusses the possibility of applying the same in the Indian rural education system. The study is based on the review and analysis of secondary sources. The researcher has accessed scholarly articles,research papers, published reports and online literature for the study

The Nexus Between Nurse Burnout, Missed Care And Patient Outcomes

Background & Significance: Nurse burnout is a healthcare crisis affecting nearly half of U.S. hospital nurses and has been tied to negative patient outcomes such as preventable adverse events – the third leading cause of death in the U.S. Despite the pervasiveness of burnout, much remains to be understood about exactly how, and to what extent, hospital nurse burnout impacts the delivery of care and patient outcomes. This study advances our understanding of the complex phenomenon of burnout by examining its impact on specific nurse-reported preventable adverse events, and positing that missed care is a pathway by which hospital nurse burnout undermines quality of care and patient safety. Methods: This cross-sectional, secondary data analysis of three linked datasets from 2005-2008 assessed a sample of 23,784 registered nurses working in 587 hospitals across four states. Employing a series of multilevel multivariable robust logistic regressions, a mediation analysis was conducted to examine the associations between hospital-level nurse burnout, hospital-level missed care, and five nurse-reported frequent adverse events (medication errors, pressure ulcers, falls with injury, hospital-associated urinary tract infections and central line bloodstream infections), after controlling for patient severity, nurse and hospital characteristics. Results: Hospital nurse burnout was found to be significantly associated with all five nurse-reported adverse events and missed care partially mediated this relationship in four out of the five outcomes. The odds of nurses reporting frequent adverse events increase by 12-20% with every 10% increase in the proportion of burned out nurses, after accounting for patient severity, nurse and hospital characteristics. Missed care was found to explain 15-33% of the relationship between hospital nurse burnout and hospital nurse-reported adverse events. Conclusion & Implications: This study provides new evidence that hospitals with higher proportions of burned out nurses have higher odds of nurse-reported preventable adverse events—partially due to missed care. To the author’s knowledge, this is the first large-scale study in the U.S. to document these associations and empirically demonstrate that missed care partially explains how nurse burnout leads to preventable harm to patients. Given the current policy climate increasingly demanding safe, high quality, value-based patient care, this study suggests that organizational-level interventions aimed at reducing nurse burnout may be a critical strategy to mitigate costly, occasionally life-threatening adverse events

VALIDATION OF THE FACTOR STRUCTURE OF THE PARENT-ADOLESCENT RELATIONSHIP SCALE IN THE INDIAN CONTEXT

Parent-Adolescent Relationship (PAR) gets transformed during adolescence, and there is a significant relationship between the adolescent\u27s adjustment and quality of this relationship. A loving and caring relationship full of acceptance with parents offers a health-oriented atmosphere for the growth of the child\u27s abilities in multiple ways. The research findings indicated that the quality of Parent-Adolescent Relationship (PAR) associates with a broader range of positive outcomes, including emotional and mental Well-being, adjustment with the environment, and social competence. The present study was designed to adopt a Parent-Adolescent Scale, which examines the parent-adolescent relation among adolescents of India. In the present study, 13 items from the Parent-Adolescent Scale 21, developed by Husseini et al. (2016), were translated in the Hindi language and adopted in the Indian context. A total 1000 adolescent students from different Hindi speaking states of India responded to the PARS13. An Exploratory Factor Analysis and a Confirmatory Factor Analysis were performed to test the factorial structure of the PARS13, and the internal consistency of the scale was studied. The results supported scale multidimensionality. The obtained Cronbach’s alpha revealed satisfactory internal consistency with a value of 0.82. Based on the psychometric properties obtained, it is concluded that PARS13 is a reliable measure to assess adolescents\u27 parent-adolescent relationship in India

Harlequin baby- case of birth of a monster baby! - A myth!

Harlequin phenotype is inherited as autosomal recessive trait. Disease has been known since 1750, atleast 100 cases have been reported worldwide in modern times. Many cases are sporadic and many others occur in consanguineous families where more than one child is affected. We report a case of harlequin baby born to a mother who had previous two similar babies and two other normal babies

RESILIENCE, EMOTION REGULATION, PEER RELATIONSHIP, HUMOR AND BODY-ESTEEM IN INDIAN COLLEGE STUDENTS

The aims of the present study were (1) to explore sex-related differences and (2) to estimate the associations between resilience, emotion regulation, peer relationship, humor, and body-esteem. A sample of Indian college students (N = 1000) took part in this study. They responded to the Hindi versions of the resilience scale, emotion regulation questionnaire for children and adolescents, peer relationship scale, humor style questionnaire, and body-esteem scale. Results indicated that men obtained higher mean scores on resilience, peer relationship, humor, and body-esteem than women. All the correlations between the variables were statistically significant and positive. It was concluded that those who consider themselves as resilient experienced greater emotion regulation, body-esteem, humor, and peer relationship

Evolution of b-values before large earthquakes of mb ≥6.0 in the Andaman region

We have considered six earthquakes of mb ≥6.0, with focal depths within 45 km, in Andaman region during 2000 to 2012 to examine the spatial variations of b-value at epicentre within a one-year period prior to the occurrence of the earthquakes. We have found a correlation between the low b for the one year time interval and the occurrence of large events. The epicentral b-values of six earthquakes are lower than 1.0 and five out of six earthquakes show very low b-value at the epicentre. Our study may indicate that b-value can be employed as a possible precursor for the forecasting of a major earthquake

Endodontic management of three-rooted maxillary second premolar in a patient with bilateral occurrence of three roots in maxillary second premolars

The possibility of bilateral maxillary second premolars having three separate roots is quite low; however, it must be taken into account in clinical and radiographic evaluations during endodontic treatment. A correct clinical and radiographic diagnosis based on knowledge of root canal anatomy and critical interpretation of radiographs is necessary for a safer and successful endodontic treatment of these teeth. Failure of root canal treatment can occur due to missed roots/canals and often diagnosed when patient experiences continuous post-operative pain and discomfort. This case report describes the root canal treatment of a three-rooted maxillary second premolar in a patient with bilateral occurrence of three roots in maxillary second premolars
