Digital disparities and vulnerability: mobile phone use,information behaviour,and disaster preparedness in Southeast Asia

This paper proposes an ecological view to investigate how disparities in mobile technology use reflect vulnerabilities in communities vis‐à‐vis disaster preparedness. Data (n=1,603) were collected through a multi‐country survey conducted equally in rural and urban areas of Indonesia, Myanmar, Philippines, and Vietnam, where mobile technology has become a dominant and ubiquitous communication and information medium. The findings show that smartphone users' routinised use of mobile technology and their risk perception are significantly associated with disaster preparedness behaviour indirectly through disaster‐related information sharing. In addition to disaster‐specific social support, smartphone users' disaster‐related information repertoires are another strong influencing factor. In contrast, non‐smartphone users are likely to rely solely on receipt of disaster‐specific social support as the motivator of disaster preparedness. The results also reveal demographic and rural–urban differences in disaster information behaviour and preparedness. Given the increasing shift from basic mobile phone models to smartphones, the theoretical and policy‐oriented implications of digital disparities and vulnerability are discussed.     

Who can be morally obligated to be a vegetarian?

Kathryn Paxton George has recently argued that vegetarianism cannot be a moral obligation for most human beings, even if Tom Regan is correct in arguing that humans and certain nonhuman animals are equally inherently valuable. She holds that Regan's liberty principle permits humans to kill and eat innocent others who have a right to life, provided that doing so prevents humans from being made worse off. George maintains that obstaining from meat and dairy products would in fact make most humans worse off. I argue that Regan's liberty principle either contradicts his equal rights view or does not permit the slaughter of another for food. I show that a different view recognizing the moral rights of nonhumans but according them less value than normal adult humans, the unequal rights view, would permit such action if human survival or health depended upon it. However, it would also permit the slaughter of innocent humans in the same circumstances. Finally, I argue that current nutritional research does not support George's contention that most humans would suffer if they ceased eating other animals and their products.

Vegetarianism,morality, and science revisited

Professor Kathryn George's Use and Abuse Revisited does not contain an accurate assessment of my On Vegetarianism, Morality, and Science: A Counter Reply. I show that she has misrepresented my moral and empirical argumentation.     

安全文化、安全科技与科学安全生产观

通过10余年来对安全文化的研究,提出了一些安全科技文化的新思路、新理念:以安全哲学及认识论的观点,研究安全文化与人的安全自护能力;从实践论和科技进步的视角,研究安全文化的发展;从安全文化的理念,探讨安全文化与安全科学的关系以及安全文化与工业发展的关系;用科学发展观看待安全生产严峻形势;讨论安全生产“五要素”与安全文化的关系;提出“安全第一”公理;特别强调提高农民安全文化素质的现实作用和战略意义;依据大安全观、广义安全文化和安全科学发展观,给出了科学安全生产观的内涵。可以认为:倡导和弘扬、发展和创新安全文化是预防或减少我国意外伤亡事故和减灾防灾的根本途径。

生态文明建设的基本关系:环境社会系统中的四种关系论

文章主要以中国古代文明为例,指出人与自然的关系在文明演化中存在分裂的现象,并初步论证了人与自然的关系可以被分解成两种关系,即人与夭的关系和人与物的关系.在人与自然关系中,从系统的整体角度考虑,将涉及到的人与自然的关系称为人与天的关系;从自然中一个个独立存在的个体角度考虑,人与自然的关系主要体现为人与物的关系.此种分解亦可以作为理解李约瑟问题的一种视角.本文将这两种关系以及人与人的关系、人与自身的关系,共四种关系,统一在三种生产理论的框架内.这样的划分对落实科学发展观,建设生态文明,发展环境管理学都有重要的理论指导意义.     

Prenatal diagnosis of congenital epulis by three-dimensional ultrasound and magnetic resonance imaging

Congenital epulis is a benign intraoral tumor that has rarely been diagnosed prenatally. We report a fetus with congenital epulis diagnosed by three-dimensional (3-D) ultrasound and fetal magnetic resonance imaging (MRI) at 35 weeks' gestation. We show an image of congenital epulis using a new ultrasound technique, the 3-D multislice view, which shows images similar to CT or MRI. This is a short case report of congenital epulis diagnosed prenatally by 3-D ultrasound using multislice view and MRI. Copyright © 2006 John Wiley & Sons, Ltd.
