Abstract In this paper I return to Hegel's dispute with Kant over the conceptual ordering of external and internal purposiveness to distinguish between two conceptions of teleology at play in the contemporary function debate. I begin by outlining the three main views in the debate (the etiological, causal role and organizational views). I argue that only the organizational view can maintain the capacity of function ascriptions both to explain the presence of a trait and to identify its contribution to a current system, for it is the only view that considers teleology as a natural cause. To establish how teleology can be considered as a natural cause, advocates of the organizational view return to Kant's analysis of internal purposiveness. However, while Kant identifies the requirements that an object must meet to satisfy the demands of teleological judgment, I suggest that he denies that we can know whether they are truly met. I argue that Hegel's philosophy of nature is better equipped to determine how internal purposiveness can be considered as a natural cause, for it grounds organization in a form of purposiveness that is more fundamental than a designer's intention.

Developing the ability for a system to self-monitor its condition is a desirable feature in many modern engineering systems. This capability facilitates a maintenance-as-needed rather than a maintenance-as-scheduled paradigm, offering potential efficiency improvements and corresponding cost savings. By using continuously updated Non-Uniform Rational B-spline (NURBs) metamodels of system performance to monitor the system condition, the onset of incipient faults can be detected by comparison to a self-generated as-built system metamodel, providing a basis for determining off-normal operating conditions. This capability is demonstrated for three distinct fault conditions prevalent in brushless DC motors. The results show that this technique can be used to develop an as-built system metamodel, develop a current system model during system operation, and detect the presence of an incipient fault condition despite the compensation provided by a feedback control system.

Abstract. Swarm satellites observations are used to characterize the extreme behavior of large- and small-scale field-aligned currents (FACs) during the severe magnetic storm of September 2017. Evolution of the current intensities and the equatorward displacement of FACs are analyzed while the satellites cross the pre-midnight, pre-noon, dusk and dawn sectors in both hemispheres. The equatorward boundaries of FACs mainly follow the dynamics of ring current (as monitored in terms of the SYM-H index). The minimum latitude of the FAC boundaries is limited to 50° MLat, below which saturation occurs. The FAC densities are very variable and may increase dramatically, especially in the nightside ionosphere during the storm-time substorms. At the peak of substorm, the average FAC densities reach 3 μA/m2, while the quite level is below 0.1 μA/m2. The dawn–dusk asymmetry is manifested in the enhanced dusk-side R2 FACs in both hemispheres. Filamentary high-density structures are always observed confirming that a substantial fraction of R1/R2 FACs is composed of many small-scale currents. In the pre-noon sector, the bipolar structures (7.5 km width FACs of opposite polarities adjacent to each other) dominate, while in the post-midnight sector the upward and downward FACs tend to form more latitudinally extended structures of a certain polarity. The most intense small-scale FACs (up to ~80 μA/m2) is observed just in the post-midnight sector. Simultaneous magnetic and plasma perturbations indicate that this structure is likely a current system of a mesoscale auroral arc.

Along gently sloping coasts of seas having rotary tidal currents, the symmetry of the rotary current is interrupted where the water is shallow As a result, residual counter currents are formed The dynamics of such a current system are described based on current measurements in the Elbe Estuary (southeastern North Sea) The residual currents of this area result in the movement of bottom sediment and are most likely responsible for a series of similar appearing morphologic features.

We have shown the development of neoliberalism as a doctrine and the basic ideas that were connected to it during if s genesis. It still remains as a question, as well as a good example, the effectiveness of a neoliberalism as a theory, which in few decades turned from a group of enthusiasts to a dominant ideology. We extracted the main principals and discussed their essence and possible relations. In a defense-offence sense, what is a noble goal from one point of view, is immoral excuse from another. At the end, we gave an overview of common definitions, main problems of defining and a personal view of defining neoliberalism. In all it's aspects, neoliberalism stands as a controversial doctrine, and the whole variety of phenomenon is being attached to it, and both strongly defended and attacked by numerous authors. What seems to be missing are authentic writers on one side who would clarify if s meaning. More important, critics should be more aimed at offering realistic and acceptable alternatives, than indicating dysfunctions of a current system.

Abstract The anodic polarization characteristics of gold and silver in chloride and sulfate media have been studied, employing potentiostatic techniques. It was found that gold produces an active-passive S-shaped curve, the form of which is not seriously affected by the presence of oxygen in the electrolyte. The stability of the passive state was greater in the sulfate than in the chloride media. Silver does not give a typical anodic polarization curve in NaCl solution, because formation of an AgCl film is the primary anode reaction. This film thickens and exfoliates at a current density of 2 a/sq ft. For this reason, silver could not be used as an inexpendable anode in an impressed current system containing chloride ions.

The use of smart devices to obtain real-time data has notably increased in the context of training. These technological tools provide data which monitor the external load and technical–tactical actions related to psychological and physical health in junior tennis players. The purpose of this paper is to monitor technical–tactical actions and physical activity during a current tennis competition in the Green stage using a Zepp Tennis Smart Sensor 2. The participants were 20 junior tennis players (under 10 years of age), with an average age of 9.46 years. The total number of strokes (n= 21,477) during 75 matches was analyzed. The study variables were the following aspects: (a) number of strokes, (b) ball impact in the sweet spot; (c) racket speed; (d) ball spin; (e) calories burned; and (f) match time. The current system of competition, based on knockout, does not meet the World Health Organization’s recommendations for daily physical activity time. Players mainly used flat forehands with a lack of variability in technical–tactical actions which did not meet the current learning opportunity criteria of comprehensive methodologies. The competition system in under-11 tennis should be adapted to the players’ characteristics by improving the variability and quantity of practice.

Abstract. Swarm satellite observations are used to characterize the extreme behavior of large- and small-scale field-aligned currents (FACs) during the severe magnetic storm of September 2017. Evolutions of the current intensities and the equatorward displacement of FACs are analyzed while the satellites cross the pre-midnight, pre-noon, dusk and dawn sectors in both hemispheres. The equatorward boundaries of FACs mainly follow the dynamics of the ring current as monitored in terms of the SYM-H index. The minimum latitude of the FAC boundaries is limited to 50∘ magnetic latitude (MLat). The FAC densities are very variable and may increase dramatically, especially in the nightside ionosphere during the storm-time substorms. At the peak of substorms, the average FAC densities reach >3 µA m−2. The dawn–dusk asymmetry is manifested in the enhanced dusk-side R2 FACs in both hemispheres. In the 1 Hz data filamentary high-density structures are always observed. In the pre-noon sector, the bipolar structures (7.5 km width FACs of opposite polarities adjacent to each other) dominate, while at the other local times the upward and downward FACs tend to be latitudinally separated. The most intense small-scale FACs, up to ∼80 µA m−2, are observed just in the post-midnight sector. Simultaneous magnetic and plasma perturbations indicate that this structure is likely a current system of a mesoscale auroral arc.

Previous definitions of deindividuation are reviewed and a current conceptualization is offered. The research literature is reviewed under possible antecedents to deindividuation. It is concluded that research has failed to confirm the causal role of deindividuation in releasing antisocial behavior. Research strategies are suggested which will help more quickly to verify or disconfirm the existence and causal role of the construct.

An escape room is a physical puzzle solving game, where participants solve a series of riddles within a limited time to exit a locked room. Escape rooms differ in their theme, environment, and difficulty, and people hence often differ on their preferences over escape rooms. As such, recommendation systems can help people in deciding which room to visit. In this paper, we describe the properties of the escape rooms recommendation problem, with respect to other popular recommendation problems. We describe a dataset of reviews collected within a current system. We provide an empirical comparison between a set of recommendation algorithms over two problems, top-N recommendation and rating prediction. In both cases, a KNN method performed the best.

An English solicitor, Jeremy Bentham, disdained the unregulated use of livestock, in the literature of 1780, which cast doubt on the inability to pay morale to animals. Animal experiment was fundamental to scientific science during his life, but it has also been a question of heated popular and intellectual discourse from decades. Since then, general understanding and attitudes have strengthened against the unethical or cruel application of animals for research purposes. Russell & Burch provided in 1959 the principles set out during UFAW of the clinical lab method. The alternative measures, replacements, or non-animal steps shall be used as alternatives for live animal methods, or methods of measurement without live animal use. The term 'alternative' refers to approaches or strategies that substitute the overall use of laboratory animals, minimize the number of animals used, or enhance a current system or technology to reduce animal stress. In recent years, the creation of alternatives to animals has been accelerated by designing projects with the intention of developing and introducing alternatives. This report summarizes the key potential approaches to animal science. An integrated use of these techniques will offer an insight into the minimal use of animals for experimental research.
