New concepts may prove necessary to profit from the avalanche of sequence data on the genome, transcriptome, proteome and interactome and to relate this information to cell physiology. Here, we focus on the concept of large activity-based structures, or hyperstructures, in which a variety of types of molecules are brought together to perform a function. We review the evidence for the existence of hyperstructures responsible for the initiation of DNA replication, the sequestration of newly replicated origins of replication, cell division (...) and for metabolism. The processes responsible for hyperstructure formation include changes in enzyme affinities due to metabolite-induction, lipid-protein affinities, elevated local concentrations of proteins and their binding sites on DNA and RNA, and transertion. Experimental techniques exist that can be used to study hyperstructures and we review some of the ones less familiar to biologists. Finally, we speculate on how a variety of in silico approaches involving cellular automata and multi-agent systems could be combined to develop new concepts in the form of an Integrated cell (I-cell) which would undergo selection for growth and survival in a world of artificial microbiology.

The Findlay-Walker model does not consider saccades generated by auditory targets or nontargets (distractors), or by bimodal stimulation. Empirical results suggest that the effects of auditory stimulation cannot easily be incorporated into the model, neither in the WHEN nor in the WHERE system. A two-stage model by Colonius and Arndt gives a quantitative account of the facilitative effects of auditory distractors on saccadic latencies toward visual targets.
This article discusses nurses’ and elderly patients’ perceptions of the realization of autonomy, privacy and informed consent in five European countries. Comparisons between the concepts and the countries indicated that both nurses and patients gave the highest ratings to privacy and the lowest to informed consent. There were differences between countries. According to the patient data, autonomy is best realized in Spain, privacy in the UK (Scotland), and informed consent in Finland. For the staff data, the best results tended to (...) concentrate in the UK. The conceptual and methodological limitations of the study are identified and discussed. Implications of the results are divided into three areas: nursing practice, education and research. In practice, the analysis of patients’ values and the ethical sensitivity of nurses are important as part of ethically good care. In nurse education, students should learn to recognize ethical problems, generally and particularly, among vulnerable groups of patients. Multicultural international research is needed in this area. This is the last of a set of five articles published together in this issue of Nursing Ethics in which the results of this comparative research project are presented. (shrink)
This article is concerned with developing a philosophical approach to a number of significant changes to academic publishing, and specifically the global journal knowledge system wrought by a range of new digital technologies that herald the third age of the journal as an electronic, interactive and mixed-media form of scientific communication. The paper emerges from an Editors' Collective, a small New Zealand-based organisation comprised of editors and reviewers of academic journals mostly in the fields of education and philosophy. The paper (...) is the result of a collective writing process. (shrink)
Die in diesem Band versammelten Arbeiten des französischen Phänomenologen Maurice Merleau-Ponty führen nicht nur auf vorzügliche Weise in dessen Philosophieren ein, sie dokumentieren darüber hinaus auch die Entwicklung neu einsetzender Reflexionen in den Jahren nach der Publikation der Phänomenologie der Wahrnehmung.
Hegels Phänomenologie beruht auf der Einsicht in die geschichtliche Existenz des Geistes und die geschichtliche Konstitution der Wahrheit. Die „Arbeit der Weltgeschichte” ist jedoch selbst nicht Thema der Phänomenologie, sondern die Aneignung ihrer Resultate im Wissen des Geistes um sich. Hegels Text verweist deshalb nicht unmittelbar auf historische Erfahrungen, sondern ist als systematisches Arrangement historisch identifizierbarer Positionen zu verstehen.
The focus of this article is on elderly patients’ and nursing staff perceptions of informed consent in the care of elderly patients/residents in five European countries. The results suggest that patients and nurses differ in their views on how informed consent is implemented. Among elderly patients the highest frequency for securing informed consent was reported in Finland; the lowest was in Germany. In contrast, among nurses, the highest frequency was reported in the UK (Scotland) and the lowest in Finland. In (...) a comparison of patients’ and nurses’ perceptions, nurses had more positive views than patients in all countries except Finland. Patients with less need for nursing interventions in Greece and Spain gave their consent less often. The German and Greek patients were older, and the results also point to an association between this and their lower frequency of giving consent. In Spain, patients who were married or who had a family member or friend to look after their personal affairs were more likely to be included in the group whose consent was sought less often. This is the fourth of a set of five articles published together in this issue of Nursing Ethics in which the results of this comparative research project are presented. (shrink)
The focus of this article is perceptions of elderly patients and nurses regarding patients’ autonomy in nursing practice. Autonomy is empirically defined as having two components: information received/given as a prerequisite and decision making as the action. The results indicated differences between staff and patient perceptions of patient autonomy for both components in all five countries in which this survey was conducted. There were also differences between countries in the perceptions of patients and nurses regarding the frequency with which patients (...) received information from nursing staff or were offered opportunities to make decisions. This is the second of a set of five articles published together in this issue of Nursing Ethics in which the results of this comparative research project are presented. (shrink)
