The non-random mixing of biomembrane components, especially saturated phospholipids, exhibits important consequences in molecular biology. Particularly, the distribution of lipids within natural and model membranes is strongly determined by the selective association processes. These processes of phospholipids take place due to the cooperative modes in multiparticle systems as well as the specific lipid-lipid interactions both in the hydrophobic core and in the region of the polar headgroups. We demonstrated that the investigation of the selective association processes of saturated phospholipids might (...) contribute to the insight of the lipid domains appearance inside the bilayer membranes. The association probabilities of like- pairs and cross- pairs from a binary mixture of saturated phospholipids were tested for both parallel and anti-parallel alignments of the polar headgroups. The present model confirms the experimental evidence for saturated phospholipids to have a high tendency for association in parallel configuration of the electric dipole moments of the polar headgroups whether the cross-sectional area of the polar headgroup is in an usual range of 25-55 2. There are three major lipid domains in a binary mixture of saturated phospholipids: lipid domains in non-mixed phase of the first mixture component, in parallel alignment of the polar headgroups; lipid domains in non-mixed phase of the second mixture component, in anti-parallel alignment of the polar headgroups; lipid domains in mixed phase. We think that the selective association processes of phospholipids are neither exclusively, nor only involved in promoting the lipid domains appearance through bilayer phospholipid membranes.

In this essay, Liviu Andreescu examines the question of whether a certain category of aprofessional acts by academics deserves protection against academic sanctions under the principle of academic freedom. Andreescu discusses two alternative views of academic freedom providing different answers to the question. He then examines some of the arguments advanced by the proponents of the more recent, restrictive theory of academic freedom against the broader, traditional theory, which in recent times has been on the defensive. Andreescu ultimately suggests (...) that the choice between the two definitions of academic freedom is a question of sound policy in specific institutional contexts, rather than a matter of conceptual consistency.

The paper discusses self-plagiarism and associated practices in scholarly publishing. It approaches at some length the conceptual issues raised by the notion of self-plagiarism. It distinguishes among and then examines the main families of arguments against self-plagiarism, as well as the question of possibly legitimate reasons to engage in this practice. It concludes that some of the animus frequently reserved for self-plagiarism may be the result of, among others, poor choice of a label, unwarranted generalizations as to its ill effects (...) based on the specific experience (and goals) of particular disciplines, and widespread but not necessarily beneficial publishing practices.

Management practices are at the heart of most organizations’ sustainability efforts. Despite the importance of values for the design and implementation of such practices, few researchers have analyzed how human values, particularly ethical values, relate to human resource management practices in organizations. The purpose of this conceptual paper is to integrate scholarship on organizational sustainability, human resource practices, and values in delineating how four specific values—altruism, empathy, positive norm of reciprocity, and private self-effacement—support effective human resource practices in organizations. This (...) set of distinct values has sustainability implications, global relevance, and ethical significance. Propositions that indicate relationships among these values, human resource practices, and organizational sustainability, as well as the effects of the resource-based view to potentiate these relationships, are developed. This analysis suggests that ethical and multicultural values are important for planning and implementing effective management practices and organizational sustainability. (shrink)
The paper deals with the role of the concept of force in different classical mechanical and field theories, pointing out the existence in all cases of a Lorentz-type expression for force. In the case of the classical theory of the gravitational field we obtain the same Lorentz-type expression.
This paper looks at the state of research on churchstate relations in post-communist Romania in order to provide an outline of the most important questions which need to be addressed in the coming years. The article consists of two parts. First, a survey of academic studies published over the past two decades on the relationship between the country’s churches and state after 1990. Secondly, a breakdown of pressing churchstate issues today, accompanied by short discussions of existing studies and suggestions as (...) to what future research should probe into. (shrink)
This paper explores the relationship between the principle of academic freedom and religiously-affiliated higher education. The arguments advanced are based on a general theory concerning the role of universities in a democratic society, and as such they are intended to apply to any such society, irrespective of the particulars of religious higher education in a specific national context. The article looks at three classes of arguments advanced against a “secular” standard of academic freedom: arguments on the nature of academic disciplines (...) in religious colleges; arguments concerning the relationship between the institutional mission of religious universities and academic freedom; and arguments from democracy and religious freedom. The paper concludes that none of these arguments are successful in claiming a different standard of academic freedom for religiously-affiliated universities; and that, further, a “secular” standard leaves such institutions adequate room to express their religious dimension.

The paper discusses the context, substance and likely implications of the European Court of Human Rights’ very recent but, in our view, historic decision in the case of Lautsi v. Italy. The article offers an outline of the case and of the decision’s motivation, a presentation of the responses, and a brief discussion of its relevance to the similar Romanian case. We examine in some detail the objections leveled against the ruling, track the progress of the Court’s relevant jurisprudence on (...) the issue, and suggest some possible consequences. (shrink)
The conference aims at explaining the term “globalization” from various perspectives. It is a problematic concept due to the fact that it allows a powerful spreading of information, economic values, services, yet it is easier to be analyzed from the ideological point of view. This may be seen at the political movements today because of its particular influence it has on these.
This study analyses several aspects of the relationship between communist censorship and literature, from the vantage point of literary sociology. Focusing on the issue of religious drama, the author intends to examine the transformations undergone by Romanian literature in the 1950s and 1960s, considering the impact of totalitarian communist ideology had upon it. What the study highlights is the game between prohibition and subversiveness, between misappropriation and reappropriation, which shaped the literary climate of that period. One of the conclusions envisaged (...) here is that despite unrelenting and excessive pressures exerted by censorship, literature resisted being turned into an ally of the Romanian Communist Party.
