Cancer is a major health problem that is widespread in elderly people. Paradoxically, older people suffering from cancer are often excluded from clinical trials and are undertreated when compared to younger patients. One explanation for these observations is age stigma (ie, stereotypes linked to age, and thus ageism). These stigmas can result in deleterious consequences for elderly people’s mental and physical health in “normal” aging. What, then, is the impact in a pathological context, such as oncology? Moreover, health care professionals’ attitudes can be tainted with ageism, thus leading to undesirable consequences for patients. To counter these stigmas, we can apply some possible interventions emerging from research on normal aging and from social psychology, such as intergenerational contact, activation of positive stereotypes, self-affirmation, and so on; these tools can improve opinions of aging among the elderly people themselves, as well as health care professionals, thus affecting patients’ mental and physical health.

Estetrol (E4) is a natural estrogen produced exclusively by the human fetal liver during pregnancy. Its physiological activity remains unknown. In contrast to ethinyl estradiol (EE) and estradiol (E2), E4 has a minimal impact on liver cells activity and could provide a better safety profile in contraception or hormone therapy. The aim of this study was to delineate if E4 exhibits an activity profile distinct from that of E2 on mammary gland. Compared to E2, E4 acted as a low affinity estrogen in both, human in vitro and murine in vivo, models. E4 was 100 times less potent than E2 to stimulate the proliferation of human breast epithelial (HBE) cells and murine mammary gland in vitro and in vivo, respectively. This effect was prevented by fulvestrant and by tamoxifen supporting the notion that ERalpha is the main mediator of the estrogenic effect of E4 on the breast. Interestingly, when E4 was administered along with E2, it significantly antagonized the strong stimulatory effect of E2 on HBE cells proliferation and on the growth of mammary ducts. This study characterizes for the first time the impact of E4 on mammary gland. Our results highlight that E4 is less potent than E2 and exhibits antagonistic properties towards the proliferative effect of E2 on breast epithelial cells. These data support E4 as a potential new estrogen for clinical use with a reduced impact on breast proliferation. [less ▲]

Most decisions made in real-life situations are risky because they are associated with possible negative consequences. Current models of decision-making postulate that the occasional, unpredictable absence of reward that may result from free choice is a negative consequence interpreted as risk by organisms in laboratory situations. I argue that such a view is difficult to justify because, in most experimental paradigms, reward omission does not represent a cost for the decision maker. Risk only exists when unpredictability may cause a potential loss of own limited resources, whether energetic, social, financial, and so on. Thus the experimental methodologies used to test humans and non-humans relative to risk-taking seem to be limited to studying the effects of reward uncertainty in the absence of true decision cost. This may have important implications for the conclusions that can be drawn with respect to the neurobehavioural determinants of risk-taking in real-life situations. [less ▲]

Magmatic rocks containing economic concentrations of iron, titanium, vanadium and phosphorous are commonly associated with massif-type anorthosites and related rocks. This rock association is part of the anorthosite–mangerite–charnockite–(rapakivi-)granite suites that are restricted to the Proterozoic. Understanding the geochemistry and emplacement mechanisms of ilmenite, magnetite and apatite ore deposits is crucial for exploration, efficient mining operations and ore processing. This review discusses the controlling factors on the grade of an ore, its mineralogy, and its major and trace element distribution. We present petrogenetic models of currently mined deposits (Lac Tio, Tellnes, Damiao) and discuss the characteristics of minor ore bodies from anorthosite provinces worldwide (Grenville, North China Craton, East European Craton, Rogaland, Laramie). Models of formation of anorthosite and related rocks are presented, as well as the nature of the possible parental magmas of the suite. A mineralogical classification of Fe–Ti ores is proposed: (1) Gabbro-noritic ilmenite ore ± apatite ± magnetite; (2) Ti-magnetite-dominated ore; (3) Nelsonite (Fe–Ti oxides + apatite); and (4) Rutile-ilmenite ore. The stability of ilmenite and magnetite is then critically reviewed and the influence of various factors, particularly oxygen fugacity and crystallization pressure, is examined. We discuss liquidus compositions of Fe–Ti oxides and the behavior of important trace elements such as Cr and V, both of which are sensitive to fO2 variations. Post-cumulus evolution of both oxides can occur due to re-equilibration with trapped liquid, re-equilibration with ferromagnesian silicates, exsolution, oxidation, reaction between ilmenite and magnetite, and metamorphic overprinting. These various processes are described and their effects on the oxide geochemistry are emphasized. Several potential ore-forming processes have been invoked and can explain the formation of huge concentration of ilmenite, ± magnetite, ± apatite. Fractional crystallization can be combined with crystal sorting and plagioclase buoyancy to produce relative enrichment of dense ore minerals. Silicate liquid immiscibility can segregate conjugate Si-rich and Fe-rich melts, the latter being enriched in Fe–Ti–P. Magma mixing can produce hybrid magmas located in a single-phase field of the phase diagram and precipitate a pure ilmenite cumulate. Alternative processes are also described, such as ejection of Fe–Ti-enriched residual melts by filter-pressing and compaction, solid-state remobilization of ilmenite in veins, and hydrothermal transport of Fe and Ti from the host anorthosite followed by concentration in veins and lenticular ore bodies. The magnetic properties of Fe–Ti ore deposits present contrasting signatures, depending on whether the natural remanent magnetization is dominated by hemo-ilmenite or multi-domain magnetite. Micro- and macro-scale deformation features of ore rocks are intimately correlated with magma emplacement, and with ballooning of the anorthosite diapir associated with gravitational sagging of dense ore bodies. Exploration perspectives show that oxide-apatite gabbronorites are interesting targets because ilmenite in these rocks is poorer in Cr and Mg, and because the Ti-resource may be combined with apatite and vanadiferous magnetite.

We consider a Vehicle Routing Problem (VRP) with deterministic orders in two periods from a set of stores. Orders in period 1 (2) can be postponed (advanced) to the other period but any diversion from the initial orders incurs a penalty. From the perspective of a Logistics Service Provider (LSP), such diversions could be beneficial if savings in the routing costs outweigh the penalties. So could they be from a store's view, as the store can set a high enough penalty to compensate the diversion from its own optimal orders. In this paper, we introduce a new model where we seek a better solution for the LSP, compared to solving two independent VRPs with fixed orders, by allowing orders to be fully postponed or advanced. We apply a branch-and-price algorithm to solve this model to optimality. Many cutting-edge techniques are implemented to have an efficient branch-and-price algorithm, and two ideas to possibly improve the upper bound are tested. We draw algorithmic and managerial insights based on our test instances. [less ▲]

“Governing by numbers” is a trend on the increase in public action. Numbers tend to pervade the politico-administrative space without questioning neither the quantification processes which produce them nor the conditions of their utilization in government. And yet the use of numbers and data in political arguments contribute to transform the terms of the debate: politics can transform data and indicators, but one should not neglect how numbers affect policymaking. This article proposes as case study the analysis of some recent transformations of public research funding mechanism in universities in French speaking Belgium. It questions the systemic effects of the use of performance indicators in public management in this sector and it proposes some starting points for a discussion of their impact on the quality of the political debate.

The present paper gives a global overview on recent developments performed at the University of Liege on structural robustness of buildings for the specific scenario ‘‘loss of a column’’. In particular, a complete analytical method to assess the response of a 2D frame losing statically one of its columns is presented in details. This method is based on the development of alternative load paths in the damaged structure and takes into account the couplings between the different parts of the structure which are differently affected by the column loss. Also, the validation of the developed method through comparison to experimental and numerical evidences is presented. [less ▲]

Political parties are key political actors in both Quebec and Wallonia. As their foremost ambition is to govern their region, these parties clearly contribute to shaping its identity and image. This chapter aims at exploring how political parties in Quebec and in Wallonia speak about their region by focusing on an analysis of their electoral manifestos for the period 1994–2014. Using a quantitative and qualitative approach combining insights from lexicometry, cognitive linguistics and political science, the aims of this contribution are (i) to unravel how the parties perceive their region and its future development, (ii) to identify relevant evolutions in their perception of their respective region, and (iii) to assess to what extent parallels can be drawn between the two regions.

This paper attempts to address the challenges of how to invest in Synthetic Biology firms, most of which are relatively new start-ups and unprofitable. Valuing an early-stage firm with only a brief operating history, little or no operating profit (or even revenue), and an immature and untested business model, could be a formidable challenge. We propose a limited number of quantitative, and a larger number of qualitative criteria. An investor may consider these when faced with analyzing a new untried business, but one he/she believes has considerable potential for success in the future. [less ▲]
