'Bio-nano interactions: new tools, insights and impacts': summary of the Royal Society discussion meeting

Bio-nano interactions can be defined as the study of interactions between nanoscale entities and biological systems such as, but not limited to, peptides, proteins, lipids, DNA and other biomolecules, cells and cellular receptors and organisms including humans. Studying bio-nano interactions is particularly useful for understanding engineered materials that have at least one dimension in the nanoscale. Such materials may consist of discrete particles or nanostructured surfaces. Much of biology functions at the nanoscale; therefore, our ability to manipulate materials such that they are taken up at the nanoscale, and engage biological machinery in a designed and purposeful manner, opens new vistas for more efficient diagnostics, therapeutics (treatments) and tissue regeneration, so-called nanomedicine. Additionally, this ability of nanomaterials to interact with and be taken up by cells allows nanomaterials to be used as probes and tools to advance our understanding of cellular functioning. Yet, as a new technology, assessment of the safety of nanomaterials, and the applicability of existing regulatory frameworks for nanomaterials must be investigated in parallel with development of novel applications. The Royal Society meeting 'Bio-nano interactions: new tools, insights and impacts' provided an important platform for open dialogue on the current state of knowledge on these issues, bringing together scientists, industry, regulatory and legal experts to concretize existing discourse in science law and policy. This paper summarizes these discussions and the insights that emerged.

Leader corruption depends on power and testosterone

We used incentivized experimental games to manipulate leader power-the number of followers and the discretion leaders had to enforce their will. Leaders had complete autonomy in deciding payouts to themselves and their followers. Although leaders could make prosocial decisions to benefit the public good they could also abuse their power by invoking antisocial decisions, which reduced the total payouts to the group but increased leader's earnings. In Study 1 (N = 478), we found that both amount of followers and discretionary choices independently predicted leader corruption. In Study 2 (N = 240), we examined how power and individual differences (e.g., personality, hormones) affected leader corruption over time; power interacted with testosterone in predicting corruption, which was highest when leader power and baseline testosterone were both high. Honesty predicted initial level of leader antisocial decisions; however, honesty did not shield leaders from the corruptive effect of power.

A Dethroned King? The Limits of State Infrastructural Power in France

Since the 1980s in Western Europe, centralized states' control over subnational territories has been deeply affected by processes of Europeanization and regionalization. These changes have raised the issue of state territorial restructuring in a particular fashion: what capacity have formerly centralized states retained to steer and control subnational territories? The article draws on Mann's concept of infrastructural power, which refers to the state's capacity to exercise control and implement political decisions over the national territory. The article applies the two main operationalizations of the concept, namely the capability of the state to exercise control and the weight of the state in the subnational territories. Empirically, the article focuses on the French state in two policy sectors (education and housing). Although France is a most likely case, this article challenges this expectation, and shows the limits of the French state's infrastructural power over the subnational territories since the late 1980s.

Le sophiste Dion de Pruse, le bon roi et l'empereur

Cet article porte sur la réflexion politique grecque au sujet du principat et sur les relations entre le sophiste Dion de Pruse (40-50 après J.-C. - après 110 ?) et le pouvoir impérial. Il propose une analyse des discours de Dion qui concernent les modèles de royauté : les quatre discours Sur la royauté (Or. I à IV), l'Agamemnon (Or. LVI), le discours Sur la royauté et la tyrannie (Or. LXII). La première partie examine les circonstances de rédaction ou de prononciation des discours, afin de distinguer différentes étapes dans la pensée politique du sophiste et dans son jugement sur la figure de l'empereur. La deuxième partie étudie les deux images du « bon » roi : le roi imparfait, soumis à reddition de compte ; l'Optimus Princeps. Cette seconde image, beaucoup plus développée, est définie à la fois par un ensemble de vertus et par l'imitation du roi des dieux. La troisième partie analyse les objectifs de Dion, compare sa réflexion avec celles des intellectuels romains du Ier et du IIe siècles, dégage sa position complexe à l'égard du principat et de la figure de Trajan. The paper focuses on Greek political thinking on principate as well as on the relations between the sophist Dio of Prusa (40-50 till 100 A.D. ?) and the imperial power. It analyses Dion's speeches on royal models : the four speeches On Kingship (Or. I to IV), the Agamemnon (Or. LVI) as well as the speech On Kingship and Tyranny (Or. LXII). The first part examines under which circumstances these speeches have been drafted and given, in order to highlight the evolution of the sophist's political thinking and his assessment of the figure of emperor. Secondly, the two images of a good king are examined : the imperfect and accountable king on the one hand, the Optimus Princeps on the other. The latter image, more largely developed, is both defined by a collection of virtues and an imitation of the king of gods. The third and last part analyses Dion's objectives, compares his thoughts with the ones of 1st and 2nd centuries Roman intellectuals and sketches his complex standpoint towards the principate and Trajan.

When Preference Is Not Satisfied but the Individual Is: How Power Distance Affects Person-Job Fit

One aspect of person-job fit reflects congruence between personal preferences and job design; as congruence increases so should satisfaction. We hypothesized that power distance would moderate whether fit is related to satisfaction with degree of job formalization. We obtained measures of job-formalization, fit and satisfaction, as well as organizational commitment from employees (n = 772) in a multinational firm with subsidiaries in six countries. Confirming previous findings, individuals from low power-distance cultures were most satisfied with increasing fit. However, the extent to which individuals from high power-distance cultures were satisfied did not necessarily depend on increasing fit, but mostly on whether the degree of formalization received was congruent to cultural norms. Irrespective of culture, satisfaction with formalization predicted a broad measure of organizational commitment. Apart from our novel extension of fit theory, we show how moderation can be tested in the context of polynomial response surface regression and how specific hypotheses can be tested regarding different points on the response surface.
