This paper discusses a new similarity measure for the anomaly‐based intrusion detection scheme using sequences of system calls. With the increasing frequency of new attacks, it is getting difficult to update the signatures database for misuse‐based intrusion detection system (IDS). While anomaly‐based IDS has a very important role to play, the high rate of false positives remains a cause for concern. Defines a similarity measure that considers the number of similar system calls, frequencies of system calls and ordering‐of‐system calls made by the processes to calculate the similarity between the processes. Proposes the use of Kendall Tau distance to calculate the similarity in terms of ordering of system calls in the process. The k nearest neighbor (kNN) classifier is used to categorize a process as either normal or abnormal. The experimental results, performed on 1998 DARPA data, are very promising and show that the proposed scheme results in a high detection rate and low rate of false positives.

The present case study would help readers to understand paternalistic leadership behavior with its underlying theory. Readers would be able to appreciate the nature of experiences employees may have while working with a paternalistic leader high on authoritarianism. This case study would motivate readers to work out appropriate strategies for working under paternalistic bosses. The teaching note sensitizes readers about the complicated relationship between paternalistic leadership and culture.
Pyramid Globe Management Institute (PGMI) is struggling to generate revenue. PGMI founder, Tugmanshu Lakhani, has to find out new sources of revenue to keep the institute functioning. He constitutes a team of three professors for starting a new academic program with a foreign university. The initial success of the team brings favor from the founder but jealousy from the colleagues reeling under job threat. High authoritarianism and interference of the founder create a problematic situation for the three professors. When the new program starts showing promising results, the founder gets apprehensive about whether the new course may hurt the enrolment in the flagship program of the institute. The authoritarian and erratic behavior of the founder had a demotivating effect on the team working for the new program. Some team members resign under pressure while three professors stay to ensure the launch of the program. The professors have to resolve the conflict between their commitment toward PGMI in a troubled time and a career uncertainty if they continue working for it. Anticipating no change in the behavior of the founder and an uncertain future with PGMI, three professors quit after the start of the new program. The founder may continue losing committed employees if he is unable to balance his authoritarianism with benevolence and moral behavior. It will create more problems for PGMI in the future.

This case can be used in organizational behavior, leadership and team-building courses in the regular Master of Business Administration (MBA) programs. The case can further be used in the executive development program, especially for analyzing the leadership problem in higher education organizations.

The purpose of this paper is to understand the perception of visually impaired undergraduate students about the digital environment in their institutions and develop an online information system suiting their requirements.
A survey was conducted on undergraduate students enrolled in ten colleges of the University of Delhi. A total of 95 visually impaired students were interviewed individually. Data collected from the respondents were analyzed and interpreted using simple percentage method and is presented in the form of figures.
The study found that maximum (35.8 percent) respondents access online electronic resources daily. Major constraints faced by them are as follows: inaccessibility of the college notice board, lack of accessibility to existing facilities and resources, lack of assistive technology facilities and unavailability of readers and writers. In total, 51.6 percent respondents indicated that it is cumbersome to access the college website because they are not designed according to the accessibility standards developed for visually impaired students. The respondents also revealed that they are not very familiar with useful devices like Vachak (Hindi Reading Device), SARA CE, Lex (Scanner for Hindi Script). The major reason cited by them is the lack of training and non-availability of trained staff.
DigitVaran contains course contents of the University of Delhi. Course contents of other Universities are not included. However, it is expected that contents related to the syllabi of other universities would be added in future.
The study will help visually impaired students to get the desired course contents conveniently. In addition, librarians of other universities can utilize the findings of the study to develop a comprehensive digital environment for visually impaired students. The study can be helpful in the assessment of digital infrastructure and services to visually impaired students by National Assessment and Accreditation Council and other funding agencies.
The study developed an information system DigitVaran to assist visually impaired undergraduate students in India. The system will help them to access the study materials and make aware of various extracurricular activities of the institutions.

The learning outcomes are as follows: to understand the cultural and ethical dimensions revolving around the issue of female feticide; to apply the lens of institutional theory with respective change management measures; and to analyze and evaluate the impact of such intervention programs such as Beti Bachao Beti Padhao in the context of emerging economies such as India.
This case attempts to highlight the innovative and effective governance approach by the Government of Rajasthan (India) and, in particular, the State Health Assurance Agency to curb the menace of female feticide and the rising cases of abortion and sex determination in an attempt to favor a male child. The case concentrates on mainly three dimensions of Indian societal ecosystem, namely, the grave concern of preference of male child over female child leading to widespread cases of female feticide in different states in India with specific focus on the state of Rajasthan; the role of cultural dimension which primarily drives such preferential treatment in rural and urban areas in India; and the importance of using effective policy measures in monitoring various activities, introduction of incentive schemes to patients for preventing sex determination and promoting the birth of female child.

The aim of this article is to demonstrate the development of environment friendly, low cost natural fibre composites by robust engineering approach. More specifically, the prime objective of the study is to optimise the composition of natural fibre reinforced polymer nanocomposites using a robust statistical approach.
In this research, the material is prepared using multi-walled carbon nanotubes (MWCNT), Cantala fibres and Epoxy Resin in accordance with the ASTM (American Society for Testing and Materials) standards. Further, the composition is prepared and optimised using the mixture-design approach for the flexural strength of the material.
The results of the study indicate that MWCNT plays a vital role in increasing the flexural strength of the composite. Moreover, it is observed that interactions between second order and third order parameters in the composition are statistically significant. This leads to proposing a special cubic model for the novel composite material with residual analysis. Moreover, the methodology assists in optimising the mixture component values to maximise the flexural strength of the novel composite material.
This article attempts to include both MWCNT and Cantala fibres to develop a novel composite material. In addition, it employs the mixture-design technique to optimise the composition and predict the model of the study in a step-by-step manner, which will act as a guideline for academicians and practitioners to optimise the material composition with specific reference to natural fibre reinforced nanocomposites.
