Free Will and the Divergence Problem

This paper presents what the authors call the ‘divergence problem’ regarding choosing between different future possibilities. As is discussed in the first half, the central issue of the problem is the difficulty of temporally locating the ‘active cause’ on the modal divergent diagram. In the second half of this paper, we discuss the ‘second-person freedom’ which is, strictly, neither compatibilist negative freedom nor incompatibilist positive freedom. The divergence problem leads us to two hypothetical views (i.e. the view of single-line determination and that of one-off chance), and these views bring humans closer to the afree side – i.e. outside of the contrast between being free and being unfree. The afree side is greatly different from the ordinary human side. This paper tries to secure the second-person freedom as a substitute for the ordinary human freedom while preventing the divergence problem from arising

As the use of ICT in the field of education is advancing, learning analytics, which aims to analyze educational data to improve learning effectiveness, is becoming popular. On the other hand, since learning data is related to privacy issues, its utilization must be carefully considered. In this paper, we focus on differential privacy as a technical privacy protection measure and investigate the usefulness of applying differential privacy to educational data analysis using public datasets

Preparation of Ba1-xLnxFeO3-δ and BaFe1-xLnxO3-δ (Ln: trivalent ion) with cubic perovskite structure and random distribution of oxide ion vacancy

Oxides with perovskite structure and random arrangement of oxide ion, such as Ba0.5Sr0.5Fe0.2Co0.8O3-δ, attract much interest as oxygen permeation material. For wide spread of oxygen permeation devices, development of new material without Co is highly desired because of high cost of Co. Recently, we reported that arrangement of oxide ion vacancy in monoclinic BaFeO2.5-δ changes from ordered to random by partial La3+ substitution for Ba2+ site, resulting in cubic perovskite structure and improvement of electrical conductivity [1, 2]. Fujishiro reported preparation of BaFe1-xInxO3-δ with cubic perovskite structure and enhancement of electrical conductivity with In substitution [3]. It is expected that material with higher property may be developed by substitution of other trivalent ion, such as lanthanoid or Y, for Ba- or Fe- site in BaFeO2.5-δ. In this work, preparation of various Ba1-xLnxFeO3-δ and BaFe1-xLnxO3-δ (Ln: trivalent ion) was examined and factors determining substitution site and crystal structure were investigated. The samples of Ba1-xLnxFeO3-δ and BaFe1-xLnxO3-δ were prepared with Pechini method. Each solution of Ba2+, Ln3+ and Fe3+ was mixed with nominal cation composition. After addition of citric acid and ethylene glycol, the solution was heated at about 450 ºC, resulting in precursor. The precursor was calcined at 700 ºC for 24 h in air, followed by 1300 ºC for 10 h in air twice. The crystal structure and lattice constants of the specimens were investigated with X-ray diffraction. The chemical state of Fe and oxygen content of the specimens were evaluated with iodometric titration. Please click Additional Files below to see the full abstract
