Wondering about the future

Will it rain tomorrow? Will there be a sea battle tomorrow? Will my death be painful? Wondering about the future plays a central role in our cognitive lives. It is integral to our inquiries, our planning, our hopes, and our fears. The aim of this paper is to consider various accounts of future contingents and the implications that they have for wondering about the future. I argue that reflecting on the nature of wondering about the future supports an Ockhamist account of future contingents according to which many of them are true. Alternative accounts which maintain that no future contingents are true, either by claiming that they are all false or by claiming that they are neither true nor false, face difficulties concerning why it is appropriate to wonder about them. Reflecting on wondering in general, and wondering about the future in particular, suggests that in wondering how the future will go, we implicitly assume that there is a determinate fact of the matter. After presenting an attractive account of interrogative attitudes that has been recently proposed by Jane Friedman and outlining some norms governing wondering, I argue that all accounts of future contingents except Ockhamism face difficulties concerning why it is appropriate to wonder about them.

Driving Simulator Study for Evaluating the Effectiveness of Virtual Warnings to Improve the Safety of Interaction Between Cyclists and Vehicles

Globally, cyclists account for 3% of all road traffic deaths, with the highest percentage occurring in Europe (8%) where the bicycle is considered a true alternative mode of transport. Among the causes of crashes are vehicles overtaking cyclists, especially on rural roads. In this study, a new application of augmented reality (AR) warnings for connected vehicles is tested by means of a driving simulator. The overall objective of the study consists in assessing the effectiveness of three proposed AR systems in improving the safety of interactions between vehicles and cyclists, especially during overtaking maneuvers. The AR systems were tested on a sample of 46 drivers and provided them with additional virtual visual information aimed at improving the driver’s risk perception and assessment of safe distance from a cyclist. The virtual warning configurations were: (i) a yellow safety zone around the cyclist; (ii) a color-changing safety zone that changes from red to green when the driver has safe lateral space to overtake the cyclist; (iii) the same color-changing security zone but with an additional acoustic warning. The AR warnings were found to be quite effective as they helped drivers overtake cyclists more safely. With AR warnings (especially with the additional audio), it was found that drivers adopted longer distances from cyclists and entered the oncoming lane less frequently, thus lowering the risk of collision with cyclists as well as the risk of head-on collision with oncoming vehicles.

By Whose Authority? Sexual Ethics, Postmodernism, and Orthodox Christianity

The traditional Christian teaching is that engaging in sexual activity, whether heterosexual or homosexual, outside the marriage of one man and one woman is sinful (as distinct from having thoughts about illicit sexual desire, which need not be sinful as long as they are not meditated and/or acted upon—in the same way that the Church teaches about any “logismoi”). In direct contrast, there are those in the Church who quite recently have begun to insist that the traditional teachings concerning sexual sin need to be changed. In particular, the effort is being made to have the Church accept homosexual behavior as not sinful or problematic in any way—at least not for committed homosexuals, as comparable to committed heterosexuals in a marriage. As we all know, this relatively recent view has been promoted heavily in the media and popular culture, and even by our national government. As we make our observations, we will particularly focus on traditional Orthodox Christianity as the fullness of the truth and, thus, the source of the true alternative to this “new” outlook that is gripping much of popular Western culture today.

An Experimental Analysis of the Electrical Parameter Variation of a Photovoltaic Module

Photovoltaic (PV) energy has been asserting itself in recent years as a true alternative for the electricity production in the future. It is well known that the accuracy of PV parameters is crucial to achieving optimal control of PV systems under any operating conditions. Although many attempts have been made to study the operating ranges of PV parameters, this remains a current research topic given the diversity of PV technologies. In this paper, the PV parameters variation with irradiance and temperature levels is experimentally analysed for a polycrystalline (poly-Si) silicon PV module. The experiment considers experimental data from 130 I-V characteristic curves measured over a typical day, considering several irradiance and temperature levels in the range 29–1023 W/m2 and 19–68 °C, respectively. The results show that PV parameters vary considerably with irradiance and temperature levels for poly-Si technology. Keywords: Photovoltaic module, Photovoltaic parameters, Singe-diode model, Irradiance and temperature influence

Vaporized Hydrogen Peroxide: A Well-Known Technology with a New Application

Hydrogen peroxide has a multitude of uses and the vapor form was first identified as a sterilant in late 1970s. Following a number of developments, vaporized hydrogen peroxide (VHP) became widely adopted in early 90s as a substitute for ethylene oxide (EO) in device and instrument processing and reprocessing in healthcare facilities. Often VHP was hailed as the replacement technology for EO. Because of key limitations such as scale, penetration, and compatibility with packaging materials, adoption to terminal sterilization of single-use devices has not commenced to any significant level. However, recent developments in sterilization chamber design and process development provide new opportunity for consideration. For future products, such as those that require “end of production line sterilization,” such limitations may be reconsidered and overcome. This article describes those challenges and how they have been addressed, with practical examples. The development of global consensus standards and leveraging the well-established knowledge of VHP sterilization with regard to microorganism inactivation and material compatibility will help facilitate wider consideration of VHP technology as a true alternative to EO in certain product applications.

A legal perspective of current challenges of the Spanish residential rental market

Purpose This paper aims to explain the main difficulties in the Spanish residential rental market becoming a true alternative to home ownership. Design/methodology/approach Currently, the Spanish rental market only meets temporary housing needs; it is very atomized and lacks professionalism. It does not provide an adequate legal framework to fulfil the parties’ aspirations (i.e. stability, affordability and flexibility for tenants; profitability, security and guarantees to landlords). The analysis of this proposition and the resulting proposal are based on six years of research, which started with the TENLAW European project. Findings Overcoming these constrains is essential to double the rate of residential leases in Spain and get closer to the European average, thus achieving a true diversification of housing tenures and avoiding future housing bubbles. Practical implications The paper makes a series of recommendations to legislators and policymakers to draft an adequate legal framework aimed at increasing the housing rental market share. This is based on the experience of mature tenancy markets in Europe, such as the German, Swiss and Austrian ones. Social implications The new proposed legal framework will help to transform the tenancy model in Spain into a functional one, making it more stable, affordable and flexible, while increasing safety and profitability for landlords. The model is also applicable, on a more general level, to all Mediterranean European countries. Originality/value Rethinking the regulation of tenancies, in a context of housing crisis and unaffordability (still a reality in many European and worldwide countries) has valuable potential for making this type of tenure more popular and for avoiding future housing bubbles.
