It addresses the evolution in the conception of the artistic fact related to science, and attempts to define the spectator＇s new role. The present document will look into the science, an and technology triad as a means to communicate issues our planet is facing through scientific dissemination focusing on the bio-art avenue for collaboration. Finally, we will outline our concept of an as a revolutionary and thoughtful form poured through our works as artistic collective expressions.展开更多

Legal admissibility of digital evidence is the ability of that evidence being accepted as evidence in a court of law. Life cycle of digital evidence is very complex. In each stage there is more impact that can violate a chain of custody and its integrity. Contact with different variables occurs through a life cycle of digital evidence and can disrupt its integrity. In order for the evidence to be accepted by the court as valid, chain of custody for digital evidence must be kept, or it must be known who exactly came into contact with evidence in each stage of the investigation. This paper presents a dynamics and life cycle of digital evidence. The Petri nets will be proposed and used for modeling and simulation of this process.展开更多

A well-developed consciousness profoundly influences a person＇s actions and conduct when solving problems of what is thought, or taught to be, right or wrong Compelling neurological evidence supports the claim that children begin to develop enduring ethical standards at an early age and that these standards are largely based on the experiences of early childhood. Essentially, the innate sense of ethics requires nurturing during infancy before it can be cognitively understood and practiced in maturity. In biological terms, the development of neural networks that regulate emotional growth, and subsequently, the capacity for ethical discrimination, depends on the infant＇s early social environment. Thus, the toddler＇s early epigenetic experiences enhance, or impede, its innate still dormant genetic potential. Importantly, personal character development and ethical discrimination begins long before the child＇s formal educational years. As a consequence, early learning has to discover ways of conserving adaptive thinking which can be applied to the choices that may confront future generations. Early ethics education, including accurate access to scientific, medical, and technological knowledge, is thus critical. Future generations will increasingly require education from a global perspective when making major ethical decisions in areas, such as nuclear technology, disposal of wastes, preservation of biodiversity, global warming, and unregulated human population growth. As long as our culture continues to reflect advances in science and technology, there is an obligation to make science education overlap with crucial periods in the advancement of ethical consciousness. Significantly, when considering the human capacity for excess at times of conflict, it is incumbent on the scientific community to integrate research-based knowledge with wide-ranging learning and problem-solving skills. Bioscience ethics, the established interface bridging applied science and applied bioethics, can assist in this process of integration. To become fully responsible adults, we must share our extraordinary cognitive talents and respect life on earth in all its rich diversity. In biological terms, human uniqueness resides primarily in our brains with its products being co-operation in family and ancestral units, long education, sophisticated language and culture, and importantly, ethical consciousness-all attributes held in trust by knowledge and wisdom for future generations.展开更多

The results show that the increasing of fluorene-vinylene unit leads to a red-shift in the spectra of absorption and fluorescence, and shortens the excited state lifetime. Meanwhile, two-photon fluorescence efficiency and two-photon absorption cross section of truxene based oligolners gradually enhance in company with the extension of π- conjugated length. In addition, the values of two-photon absorption cross section modeled on the sum-over-state approach agree well with the experimental ones. The results indicate multi-branched truxene based oligomers bearing organic materials for two-photon applications.展开更多

In this paper, I argue that Herbert Simon＇s notion of ＂satisficing＂ provides a formally well-developed and empirically well-established theory of rationality that fits well with Kuhn＇s general characterization of science. I start by considering two rival interpretations of the problem of Kuhnian rationality and introduce Simon＇s notion of satisficing. In Section 3, I show how satisficing can be used to interpret paradigm, change, rational theory-choice, relativism, and progress. On this account, Kuhnian scientists are not irrational. Rather they employ the same computational mechanism which allows humans to play chess.展开更多
