The current study examined in depth the effects of suprasegmental-based instruction on the global (comprehensibility) and suprasegmental (word stress, rhythm, and intonation) development of 10 Japanese English-as-a-Foreign-Language (EFL) learners. Students in the experimental group (n = 10) received a total of three hours of instruction over six weeks, while those in the control group (n = 10) were provided with meaning-oriented instruction without any focus on suprasegmentals. Speech samples elicited from read-aloud tasks were assessed via native-speaking listeners' intuitive judgments and acoustic analyses. Overall, the pre-/post-test data showed significant gains in the overall comprehensibility, word stress, rhythm, and intonation of the experimental group in both trained and untrained lexical contexts. In particular, by virtue of explicitly addressing L1-L2 linguistic differences, the instruction was able to help learners mark stressed syllables with longer and clearer vowels; reduce vowels in unstressed syllables; and use appropriate intonation patterns for yes/no and wh-questions. The findings provide empirical support for the value of suprasegmental-based instruction in phonological development, even with beginner-level EFL learners with a limited amount of L2 conversational experience.

BackgroundWhile community-wide interventions to promote physical activity have been encouraged in older adults, evidence of their effectiveness remains limited. We conducted a qualitative study among older adults participating in regular group exercise to understand their perceptions of the physical, mental, and social changes they underwent as a result of the physical activity.MethodsWe conducted a qualitative study with purposeful sampling to explore the experiences of older adults who participated in regular group exercise as part of a community-wide physical activity intervention. Four focus group interviews were conducted between April and June of 2016 at community halls in Fujisawa City. The participants in the focus group interviews were 26 older adults with a mean age of 74.69 years (range: 66–86). The interviews were analysed using the constant comparative method in the grounded theory approach. We used qualitative research software NVivo10® to track the coding and manage the data.ResultsThe finding ‘regular group exercise contributes to balanced health in older adults’ emerged as an overarching theme with seven categories (regular group exercise, functional health, active mind, enjoyment, social connectedness, mutual support, and expanding communities). Although the participants perceived that they were aging physically and cognitively, the regular group exercise helped them to improve or maintain their functional health and enjoy their lives. They felt socially connected and experienced a sense of security in the community through caring for others and supporting each other. As the older adults began to seek value beyond individuals, they gradually expanded their communities beyond geographical and generational boundaries.ConclusionsThe participants achieved balanced health in the physical, mental, and social domains through regular group exercise as part of a community-wide physical activity intervention and contributed to expanding communities through social connectedness and mutual support. Health promotion through physical activity is being increasingly emphasized. The study results can help to develop effective physical activity programs for older adults in the community.Electronic supplementary materialThe online version of this article (doi:10.1186/s12877-017-0584-3) contains supplementary material, which is available to authorized users.

Recent studies have suggested the importance of the neighborhood environment in determining the specific type of physical activity. However, few studies on this topic have been undertaken in Japan. This study examined the association of three types of physical activity and their associations with individual and neighborhood environmental factors among middle-aged and elderly Japanese. Participants were 2,449 adults aged 40–69 living in Fujisawa city who had undergone health checkups and responded to our survey by mail. Individual factors, the International Physical Activity Questionnaire (long form), and its environmental module acted as inputs to the study. The adjusted odds ratios (ORs) of high levels of moderate-to-vigorous intensity leisure-time physical activity (LTPA), walking for active recreation, and transportation were calculated in relation to individual and neighborhood environmental factors through multiple logistic regression models. Not working and good self-rated health were significantly associated with a higher level of each physical activity outcome. According to the adjusted ORs, higher educational attainment, higher economic status, good access to exercise facilities, and owning motor vehicles were associated with longer LTPA time. However, different sets of factors were associated with longer walking times for recreation and transportation. The results suggest that diverse individual and neighborhood environmental characteristics are associated with different physical activity outcomes. Therefore, customizing environments to become activity-friendly is necessary to increase physical activity effectively among middle-aged and elderly Japanese.

A regression curve for the north polar cap of Mars is extracted from the photographs obtained at Kwasan Observatory and at Hida Observatory during the 1979–1980 apparition. The north polar cap was first observed at Ls = 26°, and the latitude of the edge of the cap was about 66°N. The retreat of the cap stopped until Mars reached Ls = 57° when the cap started to shrink. The edge reached a latitude around 80°N at Ls = 85° and then became almost stationary. The roughly constant dimension of the north polar cap before mid‐spring appears to be a regular phenomenon. But the onset time when the cap starts to shrink after the temporary stop appears to be different from year to year. The measurements of the edge of the permanent cap showed an asymmetric shape in relation to the pole. The cap extends farther to the south for longitudes near 0° than for those near 180°. The shape of the permanent cap for Ls = 84°–101° in 1980 agrees very well with that for Ls = 97° in 1972 obtained by Mariner 9.
