Although Ramachandra Guha has demonstrated the importance of cross-cultural dialogue on environmental issues and has much to tell us about the problems of wildemess preservation in the Third World, I argue that Guha is partly wrong in claiming that deep ecology equates environmental protection with wilderness protection and simply wrong in calling wilderness protection untenable or incorrect as aglobal strategy for environmental protection. Moreover, I argue that the deep ecology distinction between anthropocentrism and biocentrism is useful in dealing with the (...) two major problems which Guha identifies as undermining the health of the planetoverconsumption and militarism. Although it is true that preservation of wildemess will not be successful unless human social dynamics are taken into consideration, nevertheless, a biocentrism which integrates critical social theory can provide the basis for an ethic that undercuts the environmental degradation from overconsumption and militarism more effectively than a human-centered system.

Although consumers are increasingly engaged with ethical factors when forming opinions about products and making purchase decisions, recent studies have highlighted significant differences between consumers' intentions to consume ethically, and their actual purchase behaviour. This article contributes to an understanding of this 'Ethical Purchasing Gap' through a review of existing literature, and the inductive analysis of focus group discussions. A model is suggested which includes exogenous variables such as moral maturity and age which have been well covered in the literature, (...) together with further impeding factors identified from the focus group discussions. For some consumers, inertia in purchasing behaviour was such that the decision-making process was devoid of ethical considerations. Several consumers manifested their ethical views through post-purchase dissonance and retrospective feelings of guilt. Others displayed a reluctance to consume ethically due to personal constraints, a perceived negative impact on image or quality, or an outright negation of responsibility. Those who expressed a desire to consume ethically often seemed deterred by cynicism, which caused them to question the impact they, as an individual, could achieve. These findings enhance the understanding of ethical consumption decisions and provide a platform for future research in this area. (shrink)
Prenatal cocaine exposure can alter the postnatal care received by rat pups. Such effects could be caused in part by alterations in pup-produced stimuli that elicit early postnatal maternal care. Pup ultrasonic vocalizations are thought to be a particularly salient stimulus, and when paired with other cues, may elicit maternal attention. Cocaine is known to acutely alter thermoregulatory and cardiac function, thus prenatal cocaine may affect vocalizations through altering these functions. The data presented here determine the impact of full term (...) prenatal cocaine exposure , saline exposure, or no exposure on thermogenic capacity, cardiac function, and the resulting ultrasonic vocalizations across the early postnatal period (days 1-5). Results indicated that while sharing many similar characteristics with saline-exposed and untreated animals, prenatal cocaine exposure was associated with specific alterations in vocalization characteristics on postnatal day 1 (PND 1), including call amplitude. Furthermore, numerous spectral parameters of their vocalizations were found altered on PND 3, including rate, call duration, and frequency, while no alterations were found on PND 5. Additionally, cocaine-exposed pups also showed a reduced thermoregulatory capacity compared to saline animals and reduced cardiac mass compared to untreated animals on PND 5. Together, these findings indicate that prenatal cocaine may be altering the elicitation of maternal care through its impact on vocalizations and thermoregulation, and suggests a potential mechanism for these effects through cocaine’s impact on developing stress systems.

What I’m calling “Subjective Logic” is a new approach to logic. Fundamentally it is a theory about what sentences mean, i.e. a theory of the proposition, but it includes an account of logical consequence, the propositional connectives, probability, and the nature of truth.
