Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Development of the new quantification methods of finger coordination movement using motion analysis
Full text link本研究では，タッピング運動の独自のアウトカム指標を検討することにより，タッピング運動の臨床における協調運動の質的側面の評価としての有用性を検討した．
研究１：健常成人29名を対象に，パデューペグボードテストとタッピング運動を行い，タッピング運動所要時間とパデューペグボードテスト達成数との相関，また，タッピング運動所要時間と力・振幅との相関を調べた．研究2 ：補足運動野に腫瘍性病変を認める脳腫瘍患者において手術中生じる特徴的な運動症状（協調運動障害）について分析した．本研究より，臨床における協調運動の質的3要素（方向，時間，力）の評価として，タッピング運動が有用である可能性が示された．The purpose of this study was to demonstrate the usefulness of the finger-tapping test as clinical evaluation of qualitative aspects of coordination movement by investigating outcome index of finger-tapping movement.
Study 1: 29 healthy volunteers were recruited in this study and they performed purdue pegboard test and tapping movement. Then correlation between movement time of tapping movement and score of purdue pegboard test were calculated. Study 2: We studied intraoperative characteristic motor symptom, namely disturbance of coordination movement, of patients with brain tumor located in the supplementary motor area. This study demonstrated that the tapping movement may be useful clinical evaluation of qualitative aspects of coordination movement, namely timing, grading, and placing.研究課題/領域番号:25750199, 研究期間(年度):2013-04-01 - 2016-03-31出典：研究課題「上肢手指の動作解析による巧緻性の新規定量化法の開発」課題番号:25750199

Reorganization mechanism of emotion recognition following brain surgery
Full text link本研究の目的は，右大脳半球の主要な機能である感情識別能力の術後回復に伴う神経機能ネットワーク再編成のメカニズムを明らかにすることである．今回，下記を明らかにした．運動前野から前頭前野後方領域は全ての基本的感情の理解に関与する領域である．一方，感情別に調べると内側前頭前野は喜び，下前頭回眼窩部は悲しみの感情において中心的役割を果たしており，この領域が損傷された場合，喜びの障害は回復するが悲しみの障害は回復しない．また，脳全体に約300箇所存在する神経線維が収束する構造物を見いだした．この解剖学的構造は脳損傷からの機能回復を説明しうる解剖学的構造体と推察される．The purpose of this study was to clarify the mechanism of reorganization for neural network of emotion recognition during postoperative recovery. In this study, we revealed the following results. The prefrontal to posterior prefrontal regions were involved in the understanding of all basic emotion recognition. On the other hand, the medial prefrontal cortex played a central role in happiness and the orbitofrontal cortex in the inferior frontal gyrus plays a central role in sadness, and when these regions were damaged, happiness could be recovered but sadness is not. The researchers also found structures where nerve fibers converge, which existed in approximately 300 locations throughout the brain. This anatomical structure might explain the functional recovery from brain damage.研究課題/領域番号:18H03126, 研究期間(年度):2018-04-01 - 2021-03-31出典：「感情識別機能の術後回復に伴う神経ネットワーク再編成メカニズムの解明」研究成果報告書 課題番号18H03126

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Neural network for activation and inhibition of right frontal lobe function
Full text link本研究プロジェクトの目的は，右前頭葉機能の賦活・抑制に関わる神経機能ネットワークの解明である．本研究では覚醒下手術，画像統計解析，および白質解剖という手法を用いて，脳の抑制に関わる機能と領域を明らかにした．本研究で解明した機能は，感情理解の抑制に関わる前頭前野内側と下前頭回眼窩部，注意の制御に関わる帯状回Zone II，運動の制御に関わる前頭斜走路後方成分である．感情理解は抑制に関わる領域の損傷により，相対する感情が顕著になった．注意と運動機能については抑制に関わる領域が障害されると，注意障害と一過性の麻痺が生じた．本研究成果はリハビリテーションの治療プログラムに応用できる可能性がある．The purpose of this study is to reveal the neural networks involved in activation and inhibition of right frontal lobe functions. In this study, we used the techniques of awake surgery, statistical analysis of images, and fiber dissection to clarify the functions and regions of the brain involved in inhibition. We found following results: the medial prefrontal cortex and the orbitofrontal region of the inferior frontal gyrus were involved in the inhibition of emotional understanding, Zone II of the cingulate gyrus related to control of attention, and the posterior component of the frontal aslant tract was involved in the control of movement. Emotional recognition was markedly different due to damage to areas involved in inhibition. For attention and motor functions, damage to the inhibitory regions caused attention deficits and transient paralysis, respectively. The results of current study may be applicable to rehabilitation programs.研究課題/領域番号:19K22801, 研究期間(年度):2019-06-28 – 2021-03-31出典：「右前頭葉機能の賦活・抑制に関わる新規神経機能ネットワークの解明」研究成果報告書 課題番号19K22801

Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
感情の種類と大脳神経線維の関連の解明
Full text link本研究の目的は低次・高次のメンタライジングに関連する神経線維を明らかにし，感情のネットワークの解明を目指すことである．本研究では，覚醒下脳腫瘍摘出術を施行したグリオーマ患者を対象として，下記２つの方法で研究を行った；1) 画像統計解析を用いて関連する領域，および神経線維を調べる．2) 覚醒下手術においてメンタライジングの評価を行い，陽性所見を認めた部位と神経線維の関連を調べる．結果，低次と高次のメンタライジングには異なる神経線維が関与することが示唆された．低次のメンタライジングには右弓状束，高次のメンタライジングには上縦束IIIと前頭線条体路が関与していた．The main purpose of the study is to reveal subcortical network of emotional process. Here we investigated the white matter tracts related to high- and low-level mentalizing.
Patients with glioma who underwent awake brain craniotomy were participated in this study. We performed following two process; 1) To analyzed relationship between white matter tract and mentalizing score, we used neulo-imaging methods including voxel-based lesion symptom analysis and tract-wise lesion symptom analysis. 2) Then, mapping sites of mentalizing assessment during awake surgery were plotted on standard brain, and were analyzed. Consequently, we revealed that different white matter tracts were involved in high- and low-level mentalizing process: the right arcuate fascicles involved in low-level mentalizing, while, the third branch of the superior longitudinal fascicles and fronto-striatal tract were related to high-level mentalizing.研究課題/領域番号:16K16422, 研究期間(年度):2016-04-01 - 2019-03-31出典：研究課題「感情の種類と大脳神経線維の関連の解明」課題番号16K16422
