An Introduction to the Simulation of Equity Investment by Using Information Literacy
Get PDF論文Article「手持ち資金は初値の2 倍」という条件で、東京証券取引所が公表している2013年のTOPIX Core30中の銘柄28社について「株式売買のシミュレーション」を行った。
その結果、以前の2 論文（川本勝2016a、2017）に比べて売り回数と成功率は大きく改善した。
しかし、この結果は、当初の研究（川本勝2014）で求まった「売買を60回程度繰り返せば、その利益は投資した原資の2 倍程度になる」という理想値には遠く及ばない。
この事実は、他の改善要素が未だ残っていることを示唆している。これは、今後の重要な研究課題である。
なお、この結果が東京証券取引所に上場している全ての企業について同様に当てはまるかどうかは、別途、調査が必要である。
これらの結果は、筆者が既に発表している5 本の論文（川本勝2014、2015、2016a、2016b、2017）の結果とも矛盾しない。“Simulation of stock trading” was carried out on 28 stocks in TOPIX Core-30 in 2013 published by Tokyo Stock Exchange under the condition that “cash on hand is twice the initial price”.
As a result, the number of times of selling and the success rate were greatly improved in comparison with those of previous two papers (Kawamoto 2016a, 2017).
However, this result is far from the ideal value that “if this trading is repeated about 60 times, its profit will be about twice as much as invested funds” which was obtained in the initial research (Kawamoto 2014).
It is suggested from this fact that there are still remained any other improvement elements. This is an important research subject in the future.
Furthermore, another inspection is necessary separately whether this finding comes under equally about all companies listed on the Tokyo Stock Exchange.
This result is consistent with the results of the 5 papers that the author already published (Kawamoto 2014, 2015, 2016a, 2016b, 2017).departmental bulletin pape
Images of Archaeologist in Japanese Comics (2): The 1980s
Get PDF研究ノートResearch Note現代のポピュラー・カルチャー（大衆文化）の一つであるわが国の漫画には、多くの作品に考古学者が登場してきた。その作品数は1980年代になると若干増加するが、その前半ではSF漫画やオカルト漫画に考古学者が登場していたのに対し、後半になるとギャグ漫画・アクション漫画・アドベンチャー漫画などに考古学者が登場するようになる。また、1980年代の考古学者キャラクターは必ずしも従来のような中年男性、スーツ姿、ステレオタイプ化したサファリ・ルックではない。実際の考古学者に近いキャラクターもあれば、映画「インディ・ジョーンズシリーズ」の影響を受けたキャラクターや女性考古学者が登場するなど、考古学者イメージが多様化している。このように考古学者が登場する1980年代の漫画作品には1970年代とは異なる傾向がみられる。The archaeologist appeared in Japanese comics which are one of the contemporary popular cultures at many works. In the 1980s, the number of the works increased a little. And while the archaeologist had appeared in SF comics or occult comics at the first half, it becomes in the second half, an archaeologist came to appear in comics full of gags, action comics, adventure comics, etc. Moreover, the archaeologist character of the 1980s is not necessarily the middle-aged man, not wore the suit, and not the stereotyped Safari look. Some character similar to an actual archaeologist, some character is subject to the influence of the movie “Indiana Jones series”, and female archaeologist character has appeared. The image of archaeologist was diversified. Thus, the comics work of the 1980s in which archaeologist appeared, has a different tendency from the comics work of the 1970s.departmental bulletin pape
A Study on Growth Measures for Business Operators in the Online Retailing of Vegetables
Get PDF論文Article本考察の目的は、野菜のネット通販における消費者の利用実態の特性を明らかにしたうえで事業者が講じるべき施策を提案することである。野菜購入におけるネット通販利用開始の前後における変化として、リアル店舗での買物頻度の減少、自宅の夕食で煮物メニューや野菜も登場する肉料理や魚料理メニューの出現頻度の増加があげられている。これを踏まえて、首都圏1都3県に住む2人以上世帯の女性を対象としてWeb アンケートを実施した。その結果、野菜のネット通販におけるネットスーパーと生協系サイトの利用回数シェアは72.5％を占めた。有効な施策は、野菜の品質による差別化を追求することに限界があるため、サイトの見やすさを追求するプロモーション戦略を講じることである。また、ショッピングモールサイトと食品宅配専門サイトの利用回数シェアは27.5％を占めた。有効な施策は、新規市場の創出を意識して、野菜の品質向上を追求する差別化戦略を講じることである。This study aims to clarify the characteristics of actual usage of consumers in the online retailing of vegetables and propose measures for business operators. Some of the changes cited in the status before and after the start of using online retailing for vegetables are a reduction in purchasing frequency at real stores and increase in the frequency of inclusion of meat and fish dishes in dinner menus at home, in which stewed items and vegetables also appear. Based on this, a web questionnaire was circulated among women from households with at least two persons, in Tokyo and in three prefectures of the Tokyo metropolitan area. It was found that the proportion of frequency of use of online supermarket and co-op sites in the online retailing of vegetables was 72.5％. A promotion strategy pursuing improvement of the site’s visibility was considered effective, since there was a limit to pursuing differentiation based on the vegetable quality alone. Moreover, the proportion of usage of shopping mall sites and food delivery specific sites was 27.5％. Considering the creation of new markets, devising a differentiation strategy pursuing improvement in the quality of vegetables was presumed effective.departmental bulletin pape
The Disaster Ancient Tumulus Restored at the Beginning of the 18th Century : A Case Study of Asabano No.1 Kofun at Sakado City, Saitama Prefecture
Get PDF論文Article本稿では7 世紀に築造され、18世紀初頭（江戸時代）に石室が修復された埼玉県坂戸市の浅羽野1 号墳（土屋神社古墳）の事例を紹介する。この古墳では天井石に残された銘文によって1707年に信州高遠の石工によって石室が修復されたことが判明している。古墳が過去に修復された事例はわが国に存在するが、本事例は極めて珍しい事例である。その理由は修復の時期や石工名が判明していること、そして石材が転用されて石像が製作されたことである。また、修復の契機となったのが当時頻発していた地震災害による古墳の被害であることも重要な点である。このように、本事例は古墳と江戸時代の人々の関係、さらには遺跡と自然災害の関係を知ることができる興味深い事例である。In this paper, I introduce Asabano No.1 Kofun (Tsuchiya jinja Kofun) in Sakado city, Saitama Prefecture which was built in the 7 th century and the stone chamber was restored at the beginning of the 18th century (Edo period). It has become clear that it was restored by the masonry of Takato, Shinshu (Nagano Prefecture) in 1707, by the inscription of a ceiling stone of the stone chamber. Although the example where the ancient tumulus was restored in the past exists in our country, this is a very new example. One reason is that the restoring age and masonry name have become clear, and another reason it that the construction stone was reused for stone statue. Moreover, it is important also that the damage of the stone chamber caused by the seismic hazard which had occurred frequently those days became an opportunity of restoration. Thus, this is an interesting example which can know the relation between ancient tumulus and people of the Edo period, and also the relation between archaeological site and natural disaster.departmental bulletin pape
Images of Archaeologist in Japanese Comics (3) : The 1990s
Get PDF研究ノートResearch Note現代のポピュラー・カルチャー（大衆文化）の一つであるわが国の漫画には、多くの作品に考古学者が登場する。その作品数は1990年代になるとさらに増加し、そのジャンルも多岐にわたる。また、数多くの遺跡や考古学者が登場する長期連載の青年漫画が出現すること、考古学者が登場する少女漫画が増加することも1990年代の特徴である。さらに、この時期の考古学者キャラクターには従来のようなサファリ・ルックの中年男性も存在するが、実際の考古学者イメージに近いキャラクターも多くみられる。この傾向は1980年代後半からの傾向を踏襲するものであるが、その背景として発掘現場などの詳細な調査に基づく作品制作、人物表現の精緻化、さらにはわが国において考古学者が認知されてきたことが考えられる。The archaeologist appeared in Japanese comics which are one of the contemporary popular cultures at many works. In 1990s, the number of works further increases and the genre is also various. Moreover, it is also the features of Japanese comics of the 1990s that the youth comics of the long-term series in which many archaeological sites and archaeologists appear, and that the number of the girls’ comics in which an archaeologist appears increases. Furthermore, while the middle-aged male of Safari look like before existed in the archaeologist character of this time, many characters similar to an actual archaeologist came to be seen. This distinction has followed the tendency of the archaeologist character of the second half of the 1980s, and can consider the works based on the research of archaeological site spot, and elaboration of character expression, and also archaeologist has recognized in Japan as that background.departmental bulletin pape
Performance Analysis of a Prioritized, Limited Round-Robin System : Influence that a portion of quanta may have on the performance
Get PDF論文ArticleIn a prioritized, limited Round-Robin (RR) system where N priority classes are allowed in a single-server system, a higher-priority request is allocated a larger number of quanta compared to a lower-priority request. The sum of the number of quanta included in each RR cycle is restricted to a fixed value. An arriving request that cannot be allocated quanta because of this restriction is either entered in the service waiting queue (the waiting system) or rejected (the loss system). Practical performance measures such as the relationship between the mean sojourn time, mean queue waiting time, loss probability, and quantum size in the case that a portion of quanta must be subtracted from the remaining sojourn time are evaluated via simulation. In the evaluation, the sojourn time of an arriving request is evaluated using the requested service time, number of quanta included in each RR cycle, and quantum size. Then, the change in the number of quanta needed before service is complete is reevaluated at the arrival and departure of other requests. Tracking these events and calculations enables us to analyze the performance of the prioritized, limited RR rule.departmental bulletin pape

Furthermore, It became apparent that the dancers regarded the past as an era where 20th Century Concert Dance was characterized by the great symbiotic relationship between the dance companies that created the performances and the choreographers that lead such performances.departmental bulletin pape
Total Fertility Rate and Family Policy
Get PDF論文Article本論文は、家族政策が合計特殊出生率に与える影響について考察する。家族政策は、子育て支援のみならず、女性就業支援、男女平等なども含めて論じる。一般的に、女性就業率が高くなると、合計特殊出生率の低下を招くと言われたが、女性就業率と合計特殊出生率の両立の可能性について考察する。一方、世界各国のデータを見ると、合計特殊出生率は、一人当たりGDPが高い国ほど低いと見られるが、時系列で見た場合、経済発展がある成熟段階に達すると、一人当たりGDPが高くなるにつれ、合計特殊出生率がU字型に回復する傾向がある。合計特殊出生率の低下を経験してきた一人当たりGDPの高い国及び地域、そして発展途上にある東南アジアと比較し、その原因についても考察する。In the industrial stage of economic development, when the female labour force participation rate increases, the total fertility rate (TFR) tends to decrease. In the case of Japan, the total fertility rate (TFR) peaked at 4.4 after the Second World War. Since then, the TFR followed a declining trend and it reached a record low point at 1.26 in 2005 (Chart 1 in the Japanese text).
It is not only Japan but also in most industrial countries that the TFR has followed a declining trend at least for a certain period. However, when female participation in the labour market and the existence of dual breadwinners become seen as normal phenomena, there is a good possibility that the TFR will begin to recover.“ The Nordic combination of high levels of female labour force participation with relatively high levels of fertility, may suggest that a sustainable level of fertility is compatible with gender equality. In Japan and Korea in Asia, and in Germany, Italy, Spain and the former communist countries in Europe, the TFR has remained at a low level, while in the Nordic countries, in the US, France and UK the movement of the TFR has changed from a decreasing trend to an upward trend.
This paper sets out to explain the main possible reasons that make it possible to divide highly industrial countries into two groups, namely, the low TFR countries and the countries that have succeeded in recovering or in keeping the TFR at a fairly high level.
By using similar reasoning, it will be possible to explain the U-shaped behaviour of TFR as an economy develops. If we express the TFR on the vertical axis and an indicator of economic development on the horizontal axis, a U-shaped line or V-shaped line will appear as shown in Chart 1.
However, the U-shaped behaviour shown above does not take place automatically. We have assumed that there are three main possible reasons to explain the change in the trend of TFR behaviour and the difference in the TFR between the lowest TFR countries and the relatively higher TFR countries among the industrialized countries.
The first reason to explain the U-shaped behaviour is that of changes in“ the traditional status relationships” and in conservative attitudes and practices aimed at maintaining these relationships. In particular, it is essential to change the differential treatment of female workers and that of male workers. Changing differential status relationships between regular employees and part-time employees is also important.
If the changes mentioned above do not take places, the increase in the female labour participation rate or the ratio of female employees to total employees will probably entail a decline in the TFR. We assume that the conflict between increasing female participation in the labour market and unchanging conservative status relationships will bring about a decreasing TFR and that renovations in conservative status relationships have positive effects on the TFR and that the reforms in conservative status relationship will have positive effects on the TFR.
Secondly, we have assumed that active family policies have positive effects on the TFR, other things being equal.
Thirdly, favourable economic performance such as higher economic growth, lower unemployment rate and bright economic prospects in future will have favourable effects on the TFR, other things being equal.
In this paper, we suggest that it is possible to predict the TFR in the near future by observing the behavior of the “marginal” fertility ratio (the difference of TFR between the year and that of the preceding year), for marginal ratio precedes the average ratio as Chart 2 in the case of Japan suggests.
In the last section of this paper we will try to show the data to support the above hypothesis, especially from the cases of high GDP per capita countries and the cases of the developing countries in Southeast Asia.
In 2009 Myrskylä、Mokko, Hans-Peter Kohler Francesko& C. Billari published a paper“ Advances in development reverse fertility declines” Nature, August 2009. They suggest that including developing countries a reversed J shaped curve will be observed. Their paper in 2009 is more comprehensive including less developed countries and used more comprehensive indicators than Maruo’ papers in 2006. However, their findings suggest as far as highly developed countries are concerned the V shaped behavior is observed.departmental bulletin pape
A Study on the Transformation of the Constitution- and State-Concept correlated with the Liberal Democratization in Modern Germany
Get PDF論文Articleグローバル化の始まりと共に「国家の退場」が叫ばれ、それと関連して政治分析における国家概念の有意性も失われて行った。こうした傾向は日本にも顕著に見られたが、西独はやや事情が異なっていた。国家概念の有意性の喪失は勿論グローバル化との関係も一部見られるが、主として西独の西欧的な自由民主政体制への転換に起因するところが大きいと見られる。19世紀末から20世紀前半期にかけてドイツでは国家学が政治研究の支配的な学問として君臨し、国家概念が有意性を有していた。それは、「人権」を重視する西欧的な政治学に対する、「行為する主体」としての国家を至上視する後発近代国家のドイツ的な自己主張の表れであったとも見られる。「人権」重視の近代憲法理念とドイツ的国家との戦い、つまり近代憲法理念と国家の相剋関係は、ナチ国家の消滅まで続いたドイツ近現代政治史を貫く赤い糸であった。
この両者の関係は憲法概念と国家概念の変容過程において反映されていた。換言するなら、憲法の挑戦を受けた国家側の対応の変化に応じて憲法概念はドイツでは改変され、それと相連関して国家の多様な側面も顕在化した。この変化はまた国家概念の多様な定義となって表れた。それは、国家学が政治分析において国家概念の有意性を高める試みでもあったと見られる。本稿では、憲法概念と国家概念の変容過程を追跡することによって、西独でボン基本法体制確立と共に、西欧的な近代憲法理念によるドイツ的国家への「浸透性」の拡大とナチ国家の敗北による西欧化の結果として、ドイツのレヴァイアサンの死を迎えた過程を明らかにした。それと共に、ドイツでも国家概念の優位性が失われ、それと共にドイツ国家学の影響力も衰退した。こうして、西欧化された世界では、政治研究においては、国家概念よりも権力概念や政治過程論、政治システム論の方が有意性をより多く有するようになった経緯をも明らかにした。It is generally said that the retreat of the state begins with the advent of economic globalization, and with that the state-concept also begins to lose its relevance in the political study. This tendency is seen in Japan. But regarding this tendency, the situations are defferent in West Germany. The reason why the relevance of the state-concept declines can certainly be found partly in the retreat of the state, but besides there is an another main reason that has a close relationship to the establishment of “liberal and democratic basic order” in West Germany. During a half century untill the end of Weimar Republic, “Staatlehre” (the theory of state) is a dominant discipline in the political study in Germany. Staatslehre is considered as the expression of German-specific self-assertion that places a great value on the state as “acting entity” against the Anglo-American science of politics that considers the fundamental human rights as the highest value. The idea of modern constitution which represents western value has been penetrating into the German body politic with the expansion of prevailing western capitalism. This conflict between the idea of modern constitution and German state was continued untill the disappearance of Natistate.
By the way, in Gemany this conflict involved Staatslehre in its academic endeavor to enhance the relevance of the sate-concept for legitimating German state’s struggle to tackle constituitional problems. One may notice that this movement brought about the transformation of constituition- and state-concept. In this thesis I would like to clarify the reason why the idea of modern constituition can prevail against German state in West Germany by tracing the process of transformation of constitution- and state-concept. And through this exploration I also would like to focus attention on the fact that the victory of the Anglo-American idea of modern constitution means the death of German Leviathan and with that German theory of the state also has lost prominent position in the political study.departmental bulletin pape
A Study of Locational Pattern of High-Grade Supermarkets in Tokyo Metropolitan Area
Get PDF論文Article日本では、第二次世界大戦後に流通業界で台頭したスーパーマーケットは、価格訴求型で大量販売をする業態として知られる。しかし、2000年代からの消費の二極化の影響で、高質な商品を扱う高級スーパーへ注目が集まったが、地理学では、その研究蓄積が十分といえない。そこで本稿は、高級スーパーの店舗立地にみられる特徴を考察している。分析の結果、高級スーパーの現存店舗のうち、開店年の古い店舗は、高級住宅地付近もしくは中心性の高い地点に店舗を構える傾向があるが、近年に開店した店舗は、都市内の各所に高密度に分布し、従来よりも展開する地区が広がっていると指摘した。もともと、高級スーパーは、高級住宅地付近の食料品店、中心市街地に立地する輸入商、一般のスーパーマーケットなどを起源とし、顧客ニーズへの対応を通じて、徐々に高級スーパーとなった。後に、事業機会の拡大、商業施設による誘致、低コストで出店可能であることなどを理由に、2000年代から小型店舗を増やした。ただし、新たな出店地区は、従来の高級スーパーが成立した地区とは性質が異なるため、立地適地とならない可能性がある。また、他の小売業態よりも初期の空間分布の偏りが著しいこと、後に試験的に小型店舗を展開するというパターンがあることが特徴的と指摘した。In Japan, supermarkets play important roles in the daily life of people after WWⅡ. Supermarkets often pursuit low price and efficiency of mass distribution system. However, economic status of Japanese people gradually changed, and retail business tried to adjust their customers’ change. It is said that the high-grade supermarkets grow their business in such a condition. Although the necessity of geographical research about the feature and locational pattern of high-grade supermarkets has increased, there are few studies about them. In this study, the locational pattern of high-grade supermarkets would be discussed, by analyzing the store location of high-grade supermarkets in Tokyo metropolitan area.
The number of Japanese high-grade supermarkets is high in the major urban areas, especially in Tokyo Metropolitan area. In the area, high-grade supermarkets locate in central Tokyo or near high-grade residential area. These areas are the original location of the supermarkets. They were small retail shops or well-known importers who sell high-quality products, and they gradually developed their management model with their customers. But, in recent years, high-grade supermarkets seek their business chances in other area and cooperate with shopping malls or station building management companies. These new store locations give chances and risks, and they developed small type of shops for these locations.departmental bulletin pape
