Identix expected to ‘perform’

A comprehensive report into the make up and performance of Identix has been released by Morgan Keegan’s equity research division. The report gives the fingerprint and facial recognition technology supplier a positive write up, and believes the company will perform in line with the S&P 500 over the next six months — and that it will outperform the growth of the biometrics industry as a whole.Visit www.compseconline.com for the latest computer security industry news     

‘Canis empathicus’? A proposal on dogs' capacity to empathize with humans

Empathy has long attracted the attention of philosophers and psychologists, and more recently, of evolutionary biologists. Interestingly, studies suggest that empathy is a phylogenetically continuous phenomenon, ranging across animals from automatic emotional activation in response to the emotions of others, to perspective-taking that becomes increasingly complex with increasing brain size. Although suggestions have been made that the domestic dog may have the capacity to empathize with humans, no discussion has yet addressed the topic, nor have experimental routes been proposed to further explore the level of emotional and cognitive processing underlying dogs' seemingly empathic behaviour towards humans. In this opinion piece, we begin by contextualizing our topic of interest within the larger body of literature on empathy. Thereafter we: (i) outline the reasons for why we believe dogs may be capable of empathizing with humans, perhaps even at some level beyond emotional contagion; (ii) review available evidence both pro and against our opinion; and (iii) propose routes for future studies to accurately address the topic. Also, we consider the use of dogs to further explore open questions regarding empathy in humans.     

Transgenic rice variety ‘IR72’ with Xa21 is resistant to bacterial blight

 An elite indica rice variety, ‘IR72’, was transformed with a cloned gene, Xa21, through particle bombardment. Molecular analysis of transgenic plants revealed the presence of a 3.8-kb EcoRV-digested DNA fragment corresponding to most of the Xa21 coding region and its complete intron sequence, indicating the integration of Xa21 into the genome of ‘IR72’. In the T₁ generation, the transgene was inherited and segregated in a 3:1 ratio. After inoculation with the prevalent races 4 and 6 of Xanthomonas oryzae pv. oryzae (Xoo), T₁ plants positive for the transgene were found to be resistant to bacterial blight (BB). We also observed that the level of resistance to race 4 of Xoo was higher due to the pyramiding of Xa21 and Xa4 present in ‘IR72’. Since the inactivation of the transgene Xa21 occurred in the two transgenic T₁ plants, a larger progeny should be obtained for selecting homozygous line with a consistently higher level of resistance to the BB pathogen.

‘Hip to be Irish’: ethnicity and Bourdieu's ‘Forms of Capital’

A ‘new Irish’ American ethnicity surfaced in the 1980s – according to a number of scholars and journalists – and is comprised of what some consider to be more ‘authentic’ and ‘traditional’ Irish cultural attributes. Defining authentic and traditional Irishness is complicated, however, by the recent influx and highly visible forms of economic capital and media attention stemming from the Celtic Tiger – the surge of economic prosperity that began in Ireland in the 1990s – and the commercializing of Irish music and dance – such as Riverdance. In this paper, I propose, through my study involving Irish language enthusiasts, that this ‘new’ form of Irish ethnicity is more the result of rather than the reason for this surge in popularity. I use Pierre Bourdieu's ‘Forms of Capital’ in questioning the ‘new Irish’ American ethnicity, arguing instead that a deeply seated, less-visible reservoir of cultural and social capital form the basis for this perceived contemporary ethnicity.

The segregation of lambs into ‘responders’ and ‘non-responders’: Response to vaccination with irradiated Trichostrongylus colubriformis larvae before weaning

Random bred Merino ram and ewe lambs were vaccinated at 1, 2 and/or 3 months of age with irradiated T. colubriformis larvae. An exponentially increasing challenge of normal larvae was given to all groups including unvaccinated controls commencing at 1 month of age. The results, based on faecal egg counts, showed a dissociation into animals which responded to vaccination (geometric mean egg count 441) and those which did not (geometric mean egg count 1567). The proportion of responders was greatest in groups first vaccinated at the earliest age (1 month). Wool growth and liveweight gains showed severe depression corresponding to peak egg counts, however, responders were less affected than non-responders. There was no correlation between haemoglobin type and resistance to challenge. Faecal egg counts after impulse challenge with 10,000 normal larvae given at about 6$\text{1}\text{2}$ months of age showed a significant ranked correlation with those obtained during the primary exponential challenge. These results confirm that a proportion of young lambs respond to vaccination with irradiated larvae, and that genetically-determined factors are implicated in the ability of animals to respond to vaccination at an early age.     

Genetics of resistance to Puccinia graminis tritici in ‘Chris’ and ‘W3746’ wheats

Summary Chris wheat possessed genes Sr5, Sr7a, Sr8a, Sr9g and Sr12. W3746, derived from the cross Chris/Baart, possessed Sr7a and Sr12. The response conferred by Sr7a was influenced by the genetic background. Although Sr7a or Sr12 alone conferred no observable resistance upon adult plants, the adult resistances of Chris and W3746 to predominant pathotypes appeared to be associated with the interaction of Sr7a and Sr12, or genes at closely linked loci.     

From ‘Norwegian citizens’ via ‘citizens plus’ to ‘dual political membership’? Status,aspirations, and challenges ahead

The Norwegian citizenship regime has gradually changed to accommodate some of the demands voiced by or on behalf of the Sami. This article describes and analyses these changes in terms of changing citizenship status for the Sami as a gradual move from ‘Norwegian citizens’ via ‘citizens plus’ to ‘dual citizens’. Sami who are registered in the electoral roster for elections to the Sami Parliament possess political rights connected to two different political systems in Norway: one with membership based on territoriality, the other with membership based on descent. The author argues that the ‘people-to-people’ approach that currently seems to guide Sami aspirations for the political future ignores the condition of dual political membership and is thus ill-suited as a point of departure for discussions of the desirable scope of the future constitutional space of the Sami Parliament in Norway.     

Local Environmental Knowledge,Talk, and Skepticism: Using ‘LES’ to Distinguish ‘LEK’ from ‘LET’ in Newfoundland

The actual evidence observed in studies of LEK (local environmental knowledge) is nearly always talk about the environment, or what we refer to as LET (local environmental talk), with the claim of studying LEK usually being built upon the implicit assumption that talk about the environment is the expression of knowledge about the environment. We suggest that it is critically important for researchers to question this assumption, especially when the distinction between LET and LEK is also emphasized by local people themselves. In the case we present here, residents of small fishing villages on the Northern Peninsula of Newfoundland are routinely skeptical about what other local residents say about the environment; that is, they engage in LES (local environmental skepticism). We suggest that paying explicit attention to LES can help distinguish LEK from LET.
