“Save our students”: contesting discourses of racist attacks against Indians down under

This paper seeks to understand the dominant civic discourses of accusation of racism leveled against the Australians as expressed by the victims of racist attacks and Indian Government officials in the Times of India and Outlook India news magazines. The aim of the paper is to understand how the logics of the discourses have constituted the racially motivated attacks on the Indian diaspora in Australia, and how the nationalistic sentiments are fostered among the diasporic Indians and the Indians in India. The paper argues that there is a mutual production of diasporic and homeland nationalism in the face of a crisis that hits the Indian diaspora in Australia. This analysis also brings to fore the ideology of multiculturalism in Australia.     

What is a Species? An endless debate

Everybody is familiar with the ubiquitous term ‘species’. But what is a species? Undeniably, this is one of the most complex dilemmas in the history of biology. There is no other concept in biology as elementary yet controversial as the concept of species. In practice, a species is regarded as the fundamental unit of comparison in all biological disciplines like systematics, evolution, ecology, ethology, physiology, and genetics. However, little agreement exists in the scientific community regarding the nature of species, whether it is a real entity or a cultural artifact, its biological significance or how to delineate a species. This article is a review of the seemingly endless debate on the species concept and its implications.     

Sexuality education in India: examining the rhetoric,rethinking the future

Comprehensive sexuality education (CSE) has been recognised globally as key to helping young people assert their sexual and reproductive rights. In India too, there is growing awareness of the importance of providing CSE not only to reduce sexually transmitted infections, unintended pregnancies and abortions but also to teach important life skills. Simultaneously, lack of political will and conflicting interests among certain religious and political factions have ensured that no uniform CSE curriculum has been implemented throughout the country. This paper analyses the Adolescent Education Programme teacher curriculum as revised in 2009–2010 by the National Council of Educational Research and Training and the United Nations Population Fund. It highlights some of the opportunities presented by the curriculum and argues that despite its intent of providing relevant sexuality education for young people, the language of the curriculum is vague, thus potentially exacerbating confusion, and excluding people who do not conform to societal stereotypes of sex, gender, and ability. In order to be holistic, any CSE programme must be inclusive, cater to diverse needs and present content in a rights-based language without adding to the socio-cultural context of mystery and shame attached to sexuality.     

Young children's causal inferences

We report 2 experiments that show a striking development between the ages of 3 and 4 years in children's ability to make causal inferences about sequences of events. The task in the first experiment was to work out what had caused the change to an object that started out as odd (noncanonical) in 1 way and ended up as odd in 2 ways--starting, for example, as a broken cup and ending as a wet and broken cup. When asked to choose the instrument that had caused the change, 3-year-olds often selected the instrument that could have caused the initial state (a hammer, in our example) and not the instrument that would produce the change. 4-year-olds hardly ever made this mistake. In the second experiment, the 3-year-olds were able to make the correct choice when the change was from a canonical to a noncanonical state (cup-wet cup) but had much more difficulty when the change was from noncanonical to canonical (wet cup-dry cup). The difference was much smaller in the older group. The first of these tasks can be solved simply on the basis of knowledge that a particular instrument can cause a particular effect without reference to the initial state. The second task requires attention to the differences between initial and final state. We conclude that the ability to make genuine causal inferences develops between the ages of 3 and 4 years.     

The madelung constant of the sodium chloride crystal lattice

An analysis of the Madelung constant of the sodium chloride crystal lattice has been made, in an effort to supplement information available in undergraduate textbooks. A method of approximation of the constant using the personal computer is presented. An erratum to this article is available at .
