The Effects of Activating Gender-Related Social Roles on Financial Risk-Taking

Previous studies observed differences between men and women in terms of their financial risk-taking. However, these differences may stem not only from the gender of the decision-maker but also from other factors, such as stereotypical gender social roles. Media content exposes both men and women to stereotypical portrayals of their gender, and this might temporarily activate thoughts related to their social roles. A question arises whether such activation might impact the way people make risky financial decisions. The present experimental study investigated whether temporarily activated gender-related social roles influence the risk-taking propensities of men and women (N = 319) in the context of gambling and investment choices. The results show that activating a stereotypically male social role (professional employee) made both men and women more prone to take financial risks relative to a control condition. Furthermore, activating a stereotypically female social role (homemaker) lowered the propensity to take financial risks in both genders for the investment domain and in women only for the gambling domain. This study contributes to the literature on gender differences in economic behavior by showing that researchers should not overlook sociocultural factors

Tilted algebras and short chains of modules

We provide an affirmative answer for the question raised almost twenty years ago concerning the characterization of tilted artin algebras by the existence of a sincere finitely generated module which is not the middle of a short chain

Powder Bed Fusion Additive Manufacturing Using Critical Raw Materials: A Review.

The term "critical raw materials" (CRMs) refers to various metals and nonmetals that are crucial to Europe's economic progress. Modern technologies enabling effective use and recyclability of CRMs are in critical demand for the EU industries. The use of CRMs, especially in the fields of biomedicine, aerospace, electric vehicles, and energy applications, is almost irreplaceable. Additive manufacturing (also referred to as 3D printing) is one of the key enabling technologies in the field of manufacturing which underpins the Fourth Industrial Revolution. 3D printing not only suppresses waste but also provides an efficient buy-to-fly ratio and possesses the potential to entirely change supply and distribution chains, significantly reducing costs and revolutionizing all logistics. This review provides comprehensive new insights into CRM-containing materials processed by modern additive manufacturing techniques and outlines the potential for increasing the efficiency of CRMs utilization and reducing the dependence on CRMs through wider industrial incorporation of AM and specifics of powder bed AM methods making them prime candidates for such developments

The critical raw materials in cutting tools for machining applications: a review

A variety of cutting tool materials are used for the contact mode mechanical machining of components under extreme conditions of stress, temperature and/or corrosion, including operations such as drilling, milling turning and so on. These demanding conditions impose a seriously high strain rate (an order of magnitude higher than forming), and this limits the useful life of cutting tools, especially single-point cutting tools. Tungsten carbide is the most popularly used cutting tool material, and unfortunately its main ingredients of W and Co are at high risk in terms of material supply and are listed among critical raw materials (CRMs) for EU, for which sustainable use should be addressed. This paper highlights the evolution and the trend of use of CRMs) in cutting tools for mechanical machining through a timely review. The focus of this review and its motivation was driven by the four following themes: (i) the discussion of newly emerging hybrid machining processes offering performance enhancements and longevity in terms of tool life (laser and cryogenic incorporation); (ii) the development and synthesis of new CRM substitutes to minimise the use of tungsten; (iii) the improvement of the recycling of worn tools; and (iv) the accelerated use of modelling and simulation to design long-lasting tools in the Industry-4.0 framework, circular economy and cyber secure manufacturing. It may be noted that the scope of this paper is not to represent a completely exhaustive document concerning cutting tools for mechanical processing, but to raise awareness and pave the way for innovative thinking on the use of critical materials in mechanical processing tools with the aim of developing smart, timely control strategies and mitigation measures to suppress the use of CRMs

Photochemical properties of the cyclopentadienyliron complex of phenothiazine

Publisher's version/PDFPhotolysis of [([eta superscript 6]-phenothiazine)([eta superscript 5]-cyclopentadienyl)]iron(II) hexafluorophosphate (1) has been examined in various solvents such as MeOH, DMSO, THF, MeCN, furan, CH[subscript 2]Cl[subscript 2], CF[subscript 3]CH[subscript 2]OH and (CF[subscript 3])[subscript 2]CHOH. Photoreactions are induced by excitation at [lambda] = 254, 313, 337, 366, 514.5 and 647.5 nm. The major reaction leads to the photorelease of phenothiazine (2) which does not react further under the reaction conditions. Quantum yields of photolysis of 1, [phi](1), and photorelease of 2, [phi]([subscript 2]), are independent of concentration in the range of 1 × 10[superscript –4]–1 × 10[superscript–2] mol dm[superscript–3], wavelength of excitation and light intensity and in MeOH, MeCN, furan and THF, [phi]([subscript 1]) = [phi]([subscript 2]) = ca. 1. The quantum yields are lower in solvents of lower nucleophilicity and in CH[subscript 2]Cl[subscript 2], CF[subscript 3]CH[subscript 2]OH and (CF[subscript 3])[subscript 2]CHOH the [phi]([subscript 1]) values are 0.45, 0.26 and 0.03, respectively. In some solvents ferrocene formation is also observed. Applying oxygen as a quencher it is found that photochemical decay of 1 takes place from the excited state [superscript 3]E[subscript 1], with a lifetime of [tau][subscript 3][Epsilon][subscript 1] < 10[superscript –8]s and leads to formation of 2
