ポスト福祉国家における経済的自由の憲法理論的研究

当初の研究実施計画に則り、(1)討議民主主義や共和主義等の研究動向を調査・検討し、経済的自由主義の保障を相対化する理論の意義と問題点の検証、(2)解釈論との関係で、経済規制に関する経済法の理論を憲法学に導入する試みの是非の検討を行った。また、以上の理論的研究と併せて、(3)規制緩和政策の下で進められる改憲動向の検討を通じて、経済的自由をめぐる憲法理論の問題を実践的に検討した。研究成果との関係で整理すると、「ジョン・ロック『自然法論』をめぐる諸考察」は、前年度の課題であったリバタリアニズムの批判的研究との関連で、ロック自然法思想の歴史的解明を試みたものである。図書『政府規制と経済法』に掲載した拙稿「憲法と独占禁止法」は、営業の自由に関する「規制目的二分論」と新聞の特殊指定の問題を憲法と経済法のそれぞれの観点から検討し、民主主義社会においては「競争」に解消できない政治的価値があり、それを憲法論的に根拠つけていくことの重要性を明らかにした。論文「憲法からみる"独占禁止法と規制緩和"」は新聞の特殊指定の問題について、さらに立ち入って検討を加えたものである。以上の二つの論稿は、(2)の調査・分析の一部を公表しだものである。論文「地方自治と改憲問題」は、各種の改憲案における地方自治規定が、規制緩和政策に適合的であることを明らかにし、「地方分権」が福祉切捨ての便法にされかねない状況を批判した。(3)の研究成果の一部である。なお、(1)の課題に関わる研究成果は、「立憲主義における社会契約論の意義」と「立憲主義と民主主義の関係」といった憲法理論の基礎的問題を扱う論稿を執筆するにあたって利用した。これらの論稿は間もなく公刊される予定である。そして、現時点では未公刊の論稿をも利用しつつ、2年間の研究成果を整理して、「ポスト福祉国家における経済的自由の憲法理論的研究」と題する報告書を作成した。科学研究費補助金 研究種目:基盤研究(C) 課題番号:17530020 研究代表者:愛敬 浩二 研究期間:2005－2006年度research repor

Dynamic Kinetics of N_2O-CO Reaction on Magnesium Oxide with Multifunctional Active Sites*

application/pdfThe heterogeneously catalysed N_2O-CO reaction was carried out on magnesium oxide with multifunctional active sites at 290-320℃ by using an ordinary tubular flow reactor under atmospheric pressure, and the transient state of reaction was analysed by the transient response method. The steady state analysis of the reaction revealed the first order with respect to the concentration of carbon monoxide and zeroth order with respect to the concentration of nitrous oxide. Three different active ｓｉｔｅｓ were considered on the catalyst surface named S_1, S_2 and S_3. CO and CO_2 were competitively adsorbed on S_1, and coadsorbed CO＋CO_2 interacted strongly with each other. N_2O was decomposed on S_2 and reacted with gaseous CO to produce CO_2. 98％ of the surface sites were occupied by S_3 which is presumed to be a subactive site for the surface diffusion of adsorbed species. The computer simulation technique using a personal computer was effectively applied to study the reaction mechanism. A possible mathematical model to analyse the proposed mechanism was presented, and a large number of transient response curves based on many different reaction sequences were simulated and referred to the experimental response curves. The model of the response curves were compared, and a possible reaction mechanism was proposeddepartmental bulletin pape

Increased Co-Localization of DNA Damage Markers Rapidly after Exposure to Radiation

<p>(A) is an analysis summary of γH2AX and ATMp co-localization with 53BP1 done in 3-D. Two RIFs are considered co-localized if the distance between their centers is less than or equal to 0.48 μm. As described in Materials and Methods, RIF centers are determined as the brightest pixel within each spot. The γH2AX co-localization is illustrated in (B) with representative images of different time points and different type of radiations. γH2AX and 53BP1 foci locations are shown as green disks and red circles, respectively. Co-localized centers are circled by a yellow contour on the image, and the amount of γH2AX co-localization is reported for each image. Both exposure to γ-rays (Cs) and 1 GeV/amu Fe are illustrated for the two different time periods considered after exposure to radiation (1–4 min and 5–10 min). Averages for Cs are based on two independent experiments, whereas averages for Fe are based on four independent experiments. A <i>t</i>-test was performed, and a <i>p</i>-value of 0.01 was computed between the first and second time period considered for γH2AX (statistical significance noted on the graph as *).</p

Illustration of Image Manipulation to Predict the Average DNA Damage Pattern along a Track for a Given DNA Density Profile

<div><p>(A) Shows a typical image of cells that have been traversed with 1 Gy of 1 GeV/amu Fe ions. After manually selecting a region that contains a clear track, foci identification and reshuffling is done as depicted by the cartoon. Foci detection is done automatically via in-house image algorithm (see <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.0030155#s4" target="_blank">Materials and Methods</a>).</p><p>(B) Further illustrates the mathematical approach used (i.e., Monte Carlo concept), where the probability of damage at a pixel location is proportional to the DNA density at the same location. This process is done iteratively (i.e., 50 randomizations per nucleus analyzed) to give a reasonable average break distribution. For each iteration, RIF position is determined by a probability less than that determined by DNA density (blue line).</p></div

Illustration of <i>Rdna</i> and <i>Rgrad</i> Measurements

<p>Three hypothetical foci patterns over the same nucleus are illustrated with their corresponding <i>Rdna</i> and <i>Rgrad</i> values. Upper images (A,C,E) are overlays of the DAPI image with the center of hypothetical foci (in red). Lower images (B,D,F) are overlays of the foci location with the gradient image of DAPI. The gradient operator is often used in imaging as an edge detector. To illustrate this, the green arrow in (C) delineates the contour of the edge of a bright DAPI region. One can see in the corresponding gradient image in (D) that the same contour correlates to a bright gradient region. <i>Rdna</i> measures the ratio of the mean nuclear intensity at the foci locations over the mean intensity of the full nucleus. <i>Rgrad</i> measures the same ratio on the gradient image. Because the boundary of the nuclear image creates a strong gradient intensity, a conservative contour is used for nuclear segmentation (shown in blue) to avoid an edge effect when calculating <i>Rdna</i> and <i>Rgrad</i>. In (A) and (B), foci are placed in areas of surrounding high nuclear density. The surrounding high density keeps the foci distal from areas of density change, thus we see the foci lie in low-intensity regions in the corresponding gradient image. This results in <i>Rdna</i> above 1 and <i>Rgrad</i> below 1. By manually placing foci at different locations with respect to DNA density regions, we show that <i>Rdna</i> is high when foci are located in bright regions of the nucleus (A) and (B); <i>Rgrad</i> is high when foci are located at the interface of bright and dim regions of the nucleus (C) and (D); and <i>Rdna</i> is low when foci are located in dim regions of the nucleus (E) and (F).</p

Spatial Foci Pattern Increasingly Deviates from Prediction Following 1 Gy of 1 GeV/amu Fe Exposure

<div><p>(A) Plots the correlation between theoretical and experimental distributions of distances between consecutive foci along Fe tracks over the first hour following exposure to radiation. All DNA damage markers used (i.e., γH2AX, ATMp, 53BP1) show the same loss of correlation to randomness over time.</p><p>(B) Shows the corresponding foci frequencies, depicting a rapidly decreasing curve indicative of DNA repair.</p></div
