Effect of caffeine on the yield of spontaneous Minute mutations in the c3G female-ywmf-2 male system of Drosophila melanogaster
Get PDFapplication/pdfThe possible effect of caffeine on the c3G femal-ywmf-2 male system which is proposed to be responsible for an extraordinarily high yield of production of spontaneous Minute mutations (Miyamoto, 1992) was studied. Prior to mating, the c3G females were fed on caffeine in honey solution at their age of 0-8 h for three days. These females were mated and allowed to lay their eggs for 12 days by transferring them every day to fresh food(summarized as six two-day broods, broods A-F). The yield of spontaneous Minute mutations was determined and compared between the caffeine and non-caffeine treated series of experiments. The results show that the yield of spontaneous Minute mutations recorded in broods A and D of caffeine series is significantly lower than that in the non-caffeine series. The significant difference between these two series is also observed in the total yield of these mutations of the six broods. These findings clearly indicate that the yield of Minute mutations is reduced by the caffeine pretreatment of c3G females. This possibly suggests that the c3G female-ywmf-2 male system may have a caffeine sensitive nature
The Employment of Women and the Role of the Junior College in their Education － A Report and Investigation into the Place of Employment of Graduates of Takamatsu Junior College, Department of Secretarial Studies －
Get PDFapplication/pdfThe purpose of this paper is to clarify what kind of person Japanese employers are seeking under the recent drastic changes of the management environment, and to consider how we should educate students in junior colleges in the future. To this end, we have sent out questionnaires to personnel departments at various companies and businesses where previous graduates of the department of secretarial studies at Takamatsu junior college have been employed. The results of the investigation are as follows : 1 ) The job shortage trend will continue in the future. 2 ) When graduates of junior colleges are employed, traits such as "common sense" and "personality" are strictly evaluated. 3 ) More graduates are expected to be hired for not only staff work but also line production in the future. In addition, they will have to do more work involving human relations. 4 ) Junior colleges are expected to help the students develop "common sense" , "culture" and "business ability"

An analysis of university students' study-attitudes during senior high-school days in educational psychology.
Get PDFapplication/pdfThe purpose of this study was to investigate study-attitudes during the senior high-school days of recent university students in Japan. One hundred and eighty six undergraduate students (most of them freshmen) answered a questionnaire. The results are as follows : (1) 70% of the students attended school regularly, but 20% were often late for school. (2) For most students, their study-attitudes in senior high-school days were not so good. (3) They studied for about one and a half hours at home on average. (4) Senior high-school attendance was closely related to university day's attendance. Finally, the current trend of low achievement levels by university students in Japan was discussed m this paper
A characteristic of attack ability in handball game － Comparison of intercollege high rank schools and Chugoku and Shikoku college league schools －
Get PDFapplication/pdfThe purpose of this study to scale attacking performance in handball games and analyzed a game by score, and observed the whole image and characteristic of attacking performance by a different level. The observation materials are intercollege high rank schools and Chugoku and Shikoku college league schools. The result can be summarized as follows. 1) The attack frequency and goal number was 63. 8 times and 22. 1 points on total average, and as for attack success rate, intercollege high rank school was high. 2) For high attack success rate, hold down a mistake rate to less than 25%, and it is important to make shot success rate more than 50%. 3) As for the occupation rate of goal watched according to a position, a difference was found every a team, and this was except with competition level of each team by difference of assembly of attacking structure
Are Investors Really Overconfident In Stock Market? : On the Hypothesis of Behavioral Finance
Get PDFapplication/pdfThe purpose of this paper is the reconsideration of the overconfidence hypothesis usually introduced in textbooks related to behavioral finance. In this paper, we expect investors'overconfidence to depend on varied circumstances. So we developed a survey representing two factors : ( 1 ) punishment for mistakes and ( 2 ) no punishment for mistakes. We present evidence that there is great improvement in the rate of correct answers in survey with punishment This evidence can be interpreted that investor's overconfidence is not so large as the supporters of pro-behavioral finance insist
Rethinking typological universal, deontic > epistemic － The case of Japanese modal marker 'monoda' －
Get PDFapplication/pdfモダリティを表す語嚢形態であるモーダルマーカーが、 1つの形式で2つ以上のモダリティとして機能する多義性(polysemy)を持つことは異なる言語間で確認され、この多義性は義務や許可を表す「行為拘束的モダリティ(deontic modality)」と話者の命題に対する意見の表明を表す「認識的モダリティ(epistemic modality)」の間で議論される。またこの多義性は「行為拘束的モダリティ」から「認識的モダリティ」が派生したものであり、その逆ではないという文法化の「一方向性仮説(unidirectionality hypothesis)」が言語類型論的普遍性(typological universal)であると見なされている。しかし、最近ではこの類型論的普遍性である多義的アプローチに対して、モーダルマーカーは1つの中核的意味特性からなり、どの用法を意味するかは文脈によって決定されるという単義的アプローチ(例：Kratser 1981, Papafragou 2000)が注目を集めている。本研究では、複数の機能をすると見なされている日本語のモーダルマーカー「ものだ」の「行為拘束的モダリティ」と「認識的モダリティ」の用法の関係を考察し、単義的アプローチによる説明の妥当性を主張する。分析において、機能主義言語学に基づく言語習得理論である「競合モデル(Competition Model)」 (Bates & MacWhinney 1981)による「キュー(cue)」の概念を用い、競合モデルが言語習得だけでなく文法化の分野においても適用可能であることを述べたい
