Culture study is highly interdisciplinary, and thus a culture learning class in an educational institution often deals with many different cultural aspects. Accordingly, on different cultural topics ...to discuss in the class, it cannot be helped that students exhibit different degrees of interest on each topic. The current paper reports research on what kind of topics interest students based on gender and country of origin. The survey results showed great variation among students. Asian and female students relatively prefer less serious topics while male and European students tend to prefer serious and controversial topics to discuss with peers.
This study investigated phonological adaptation of non-loan words in Japanese and their preference for either deletion or epenthesis. Earlier studies argue that non-loan Japanese words prefer ...deletion while loanwords prefer epenthesis. Studies further show that the input medium affects the adaptation; text-input leads to epenthesis while sound-input to deletion. The present study experimented with text-input of non-loan nonce words and investigated how native Japanese speakers adapt their causative, passive, and potential forms. Results showed a strong preference for deletion in causative forms, a relatively weak preference for deletion in potential forms, and no significant preference in passive forms. The outcome indicates that deletion is not present by default, and further investigation is needed to define factors that influence the selection.
This study investigated native English speakers’ acquisition of the constraint for topic-wa and the preference for subject-ga in multiple-clause sentences in Japanese. The constraint for topic-wa is ...that the topic-wa cannot appear in certain types of subordinate clauses, and the preference for subject-ga is that the overt subject-ga in a subordinate clause should not overlap the topic for a matrix clause. Two sentence-completion experiments were conducted with native English-speaking participants, who were considered advanced-level Japanese learners, as well as native Japanese-speaking participants (the control group). The results indicated that although English speakers followed the constraint for the topic-wa, they frequently used the topic-wa as non-subject topics (unlike native Japanese speakers) when an embedded subordinate clause intervened between the topic-wa and the rest of the matrix clause. Also, English speakers used the same subject-ga for both subordinate and matrix clauses, unlike the native Japanese speakers’ preference. The outcome implies that English speakers associated the topic-wa with English non-subject topics, and the subject-ga with English subjects.
This study investigates reference resolution with repeated-name anaphors in Japanese, particularly focusing on (i) subject anaphor with the nominative postposition ga, (ii) topic-subject anaphor with ...the topic postposition wa, (iii) scrambled object anaphor with the accusative postposition o, and (iv) topic-object anaphor with the topic postposition wa. A self-paced sentence-by-sentence reading experiment was conducted using two-sentence discourse items followed by comprehension questions, aiming to examine which type of anaphor would trigger a faster realization of the anaphor-antecedent relationship. The discourse items included antecedents in the first sentence and anaphors in the second sentences, and the comprehension questions asked about the antecedents in the first sentences. Results showed that the comprehension questions for the discourses that included topic anaphors (topic-subject-wa and topic-object-wa) were responded to faster than those for the discourses that included non-topic anaphors (subject-ga and scrambled object-o). The results indicate that anaphors’ topic-hood given by wa facilitates the realization of antecedents.
In Japanese sentences, the default word order is ‘subject-object-verb’ (SOV). However, Japanese allows scrambling of noun phrases (NPs), for example ‘object-subject-verb’ (OSV) as opposed to the ...unscrambled default order. Two self-paced reading experiments in the moving window paradigm were conducted to test the effects of syntax, semantics and discourse in native Japanese and native English speakers’ processing of scrambled Japanese sentences. The first experiment examined how the syntactic factor (NP order) and semantic factor (NP animacy) affect processing of Japanese sentences. Results revealed that animacy difference between the subject-NP and object-NP contributes more to native English speakers’ processing than default SOV word order, whereas no such difference was found for native Japanese speakers. The second experiment examined the discourse effect in processing of scrambled OSV sentences. The experiment revealed that the processing of Japanese scrambled sentences is facilitated by the preceding context for both native Japanese and English speakers.

This paper reports on the outcomes of a Collaborative Online International Learning Activity (COIL), conducted between a Japanese and an American university. Both schools gave their students a total ...of eight weeks of activity. Sixty students from two institutions participated in this study. During each week, students received various cultural topics to discuss, and students from both schools exchanged opinions on Zoom. The Social Networking Approach (SNA) (“3x3+3”) was used to assess students’ competencies: the three content realms contain (1) linguistic; (2) cultural; and (3) global social domains, and within each of these three domains, three different skills: (i) “Can Understand”; (ii) “Can Do”; (iii) “Can Connect”, that need to be developed in language education. Our findings show that Zoom Talk provided a positive experience for the students by facilitating connectivity among the participants. However, Japanese students were more confident in their “can understand” than “can do” skills whereas the American data was entirely positive, making determination difficult.
Protein misfolding is considered a key event in the pathogenesis of polyglutamine disease such as Machado–Joseph disease (MJD). Overexpression of chaperone proteins and the application of chemical ...chaperones are reported to suppress polyglutamine induced cytotoxicity in vitro and in vivo. The effects of compatible solutes, which are osmoprotectants in bacteria and possess the action in stabilizing proteins under stress, have not, to our knowledge, been studied. We explored the protective effects of the compatible solutes ectoine, hydroxyectoine, and betaine on apoptotic cell death produced by the truncated MJD gene product with an expanded polyglutamine tract in cultured neuro2a cells. Ectoine, but not hydroxyectoine or betaine, decreased large cytoplasmic inclusions and increased the frequency of nuclear inclusions. Immunoblot analysis showed that ectoine reduced the total amount of aggregates. Despite the presence of nuclear inclusions, apoptotic features were less frequently observed after ectoine application. Our findings suggest that ectoine, a natural osmoprotectant in bacteria, may function as a novel molecule protecting cells from polyglutamine-induced toxicity.
This study investigated native English speakers’ comprehension of Japanese sentences in which relative clauses are embedded. Specifically, this study contrasted between (a) short-before-long ...sentences with center-embedded relative clauses and (b) long-before-short sentences with non-center-embedded relative clauses. Sentence-type (a) indicates a sentence that includes a short phrase before a long phrase and includes a relative clause that is embedded in the middle of the sentence, e.g., Onna-ga Ken-ga kiratteiru giin-o hometa ‘The woman praised the senator who Ken hated’. Sentence-type (b) indicates a sentence with a long phrase before a short phrase and includes a relative clause that is embedded peripherally, e.g., Ken-ga kiratteiru onna-ga giin-o hometa ‘The woman who Ken hated praised the senator’. Experiment 1 revealed that native English speakers, who are learners of Japanese, comprehended the type (b) sentences with long-before-short phrases and with non-center-embedded relative clauses more accurately than the type (a) sentences with short-before-long phrases with center-embedded relative clauses. The results indicate that the preference for the non-center-embedded clauses to center-embedded clauses is universal across languages, while the preference for short-before-long phrases is language-specific. However, Experiment 2 indicated that the different accuracy rates in comprehensions of (a) and (b) disappeared when the matrix subjects are marked by the topic-morpheme wa. The outcome indicated that the topic phrases are immediately interpreted as a part of main clauses.
