Reading Yamada Eimi
No full textThe Japanese novelist Yamada Eimi has published many controversial and
popular books. As she herself lives openly and controversially in the same way
that she writes, Yamada Eimi the person is often confused with the narrators of
her stories. This essay is not only a reading of her texts, but also an analysis of
how "Yamada Eimi," the author, is embedded into these texts and then consumed
by the reader.
Starting first with two examples of diametrically opposed readings by the
North American critics Richard Okada and Kuwahara Yasue, I then outline my
reading which falls somewhere in between Okada's and Kuwahara's. Several
Japanese readings of Yamada's writings indicate that Yamada creates her own
world with its own value system and then draws the readers into this system. In
Chapter One, a close reading of three of Yamada's works shows that this system is
an aesthetic code that defines the behaviour, dress and attitude of the female
characters in the stories. Chapter Two then shows how this code is communicated
to the readers. The homosocial "sister" relationships that allow this
communication are also part of how the readers are drawn in. In Chapter Thriee I
combine the aesthetic code with the "sister structure" to illustrate how the reader
is also included in a sister relationship with Yamada Eimi.. Back full circle, I then
show how different readings of the same texts become possible.Arts, Faculty ofAsian Studies, Department ofGraduat

Neorealism and the Chinese ideology in Yamada Yoji's family films
No full textBesides Tora-san series and samurai trilogy, veteran Japanese filmmaker Yamada Yoji also endeavors in making family films, however, his ‘home drama’1 genre has long been neglected in academia. To fill this gap, the aims of this research are to investigate firstly the aesthetics of his social realistic films; secondly, what are the family values revealed in his family films and thirdly, how ‘woman’ is portrayed in his ‘home drama’.
Working under the ‘director system’ of Shochiku Studio, this research argues that auteur theory which advocates director as the author of a film is applicable to Yamada and is thus employed to examine family films that are produced between 1970 and 2013. Background information of the auteur (author) and his films are reviewed in Part I of this thesis while Part II will focus on the discussion and analysis of the film aesthetics and motifs of Yamada Yoji’s family films.
Similar to other cultural artefacts, film aesthetics cannot stand apart from the surrounding culture. Italian neorealism which flourished at the time when Yamada entered the film industry will be used to examine Yamada’s stylistic orientation. It is found that except collaborating with professional actors, Yamada’s films display most of the characteristics of Italian neorealism. In the pursuit of aesthetic realism, the “repeated team” (also known as ‘director’s team’) of Yamada at Shochiku Studio helped him to actualize his film aesthetics. With its adoption of ‘director system’ and ‘star system’, Shochiku is also known for producing shomingeki (film of ordinary people), so besides the possible influences from Italian neorealism, Shochiku Studio may have also cast influences to the artistic style of Yamada Yoji.
Through intertextual reading of his social realistic films, the kind of social problem always lies in the dilemma between tradition and progression. Viewing ‘family’ as the fundamental unit of a society, Yamada presents to us the importance of preserving traditional virtues and family values in the continuation of a family so as to the sustainability of a society. This research reaffirms the influence of Chinese ideology on the construction of Japanese family system that the family relationships and the core family values found in films can well be explained by Chinese Confucianism.
Under the patriarchal social context, it is interesting to discover the portrayal of ‘strong woman and weak man’ image in his family films. While the oppression of women is depicted in the process of modernization, the image of ‘strong woman’ is presented through the inscription of femininity in Yamada’s cinematic film texts. Rejecting the binary opposition of sexes, women in Yamada’s films is portrayed to encompass the qualities of masculinity and femininity under the ecriture feminine writing of Yamada. This feminine approach can be regarded as a way out, as proposed by the auteur, to tackle social challenges.
Through an in-depth examination of Yamada Yoji’s family films, this research demonstrates that is a good way to learn more about a culture or a society through social realistic cinema.published_or_final_versionJapanese StudiesDoctoralDoctor of Philosoph
Interpopulation variation of behavioural and morphological traits that affect downstream displacement of the juvenile white‐spotted charr Salvelinus leucomaenis
No full textDownstream displacement is a riverine phenomenon in which organisms are advected by water flow from their home river section to a downstream area. Water flows that cause downstream displacement can be divided into two types: flood flows (Chapman & Kramer, 1991; Good et al., 2001; Meffe, 1984; Sato, 2006; Weese et al., 2011; Yamada & Wada, 2021) and flows under ordinary river conditions (i.e., ordinary flows; Lechner et al., 2016; Nagel et al., 2021; Thiesmeier & Schuhmacher, 1990). Although flood flows can cause catastrophic downstream displacement (Meffe, 1984; Sato, 2006; Weese et al., 2011), occurrences of such downstream displacement are often trait-dependent in riverine fishes (Blondel et al., 2021; Chapman & Kramer, 1991; Good et al., 2001; Meffe, 1984; Yamada & Wada, 2021). For example, smaller individuals are more likely to be displaced by strong floods from their home river section in populations of the molly Poecilia gillii (Kner 1863) (Chapman & Kramer, 1991) and the Trinidadian guppy Poecilia reticulata Peters 1859 (Blondel et al., 2021). Downstream displacement due to ordinary flows can also remove individuals with vulnerable traits from upstream populations. For example, reduced use of low-current habitats in the stickleback Gasterosteus aculeatus (Linnaeus 1758) is correlated with increased downstream displacement under ordinary flow conditions (Jiang et al., 2015). Thus, downstream displacement can be a general evolutionary pressure that removes individuals with low resistance to flow-driven displacement from their home river reaches (Yamada & Wada, 2021)

Singularities of tangent surfaces to generic space curves
No full textWe give the complete solution to the local diffeomorphism classification problem of generic singularities which appear in tangent surfaces, in as wider situations as possible. We interpret tangent geodesics as tangent lines whenever a (semi-) Riemannian metric, or, more generally, an affine connection is given in an ambient space of arbitrary dimension. Then, given an immersed curve, we define the tangent surface as the ruled surface by tangent geodesics to the curve. We apply the characterization of frontal singularities found by Kokubu, Rossman, Saji, Umehara, Yamada, and Fujimori, Saji, Umehara, Yamada, and found by the first author related to the procedure of openings of singularities
