In this study, we assessed the invariance in the factor structure underlying English-language proficiency for two groups of adolescent learners in Japan: students in middle school (ages 13-15 years) and students in high school (ages 16-18 years). Language proficiency was measured using the "TOEFL Junior"® Comprehensive test, an assessment designed to measure the English skills of adolescent English learners in non-English-speaking countries. The study results indicate that a correlated 4-factor model corresponding to the 4 language abilities of reading, listening, speaking, and writing best represents the nature of language proficiency in the 2 groups of adolescent English learners. Moreover, the factor structure is invariant across these 2 groups. However, there is a statistically significant difference in performance on the reading construct. The results are consistent across 2 random samples, thus providing confirmatory evidence of model invariance.This study provides empirical support for the current score-reporting practices for the TOEFL Junior Comprehensive test and suggests that the test scores have the same meaning across test takers from middle school and high school.

This study assessed the factor structure of the Test of English for International Communication (TOEIC®) Listening and Reading test, and its invariance across subgroups of test-takers. The subgroups were defined by (a) gender, (b) age, (c) employment status, (d) time spent studying English, and (e) having lived in a country where English is the main language. The study results indicated that a correlated two-factor model corresponding to the two language abilities of listening and reading best accounted for the factor structure of the test. In addition, the underlying construct had the same structure across the test-taker subgroups studied. There were, however, significant differences in the means of the latent construct across the subgroups. This study provides empirical support for the current score reporting practice for the TOEIC test, suggests that the test scores have the same meaning across studied test-taker subgroups, and identifies possible test-taker background characteristics that affect English language abilities as measured by the TOEIC test.

The Mediterranean diet, listed as the intangible cultural heritage of humanity by UNESCO, is known as healthy and consumed worldwide. The Japanese diet is also listed and considered healthy. This narrative review compares the Mediterranean diet with its Japanese counterpart. Research has reported that people in Mediterranean regions, such as Italy and Greece, have one-third of the mortality ratio from cardiovascular diseases compared to people in the United States and Northern Europe because of the difference in eating habits. Therefore, Mediterranean diets are considered as healthy. A typical Western diet containing high amounts of fat, sugar, and calories is responsible for several diseases like metabolic syndrome and obesity, which are induced by chronic inflammation. In contrast, Mediterranean and Japanese diets contain them only less. The similarity between Mediterranean and Japanese diets is the substantial intake of vegetables, beans, and fish. On the other hand, the Mediterranean diet consumes large amounts of olive oil, especially polyphenol-rich extra virgin olive oil and dairy products, but meat consumption is relatively small. In contrast, the Japanese diet does not use oil and fat, contains abundant fermented foods, and consumes seaweed. Japan is known for its longevity, and people think that a well-balanced diet daily is good for preventing and curing illness. In this regard, finding non-disease conditions, so-called "ME-BYO," and curing them before the manifestation of diseases is becoming more common. In this review, we discuss the healthy eating habit, "The Mediterranean-styled Japanese diet," which prevents ME-BYO condition and reduces the risk of various diseases. The Mediterranean-styled Japanese diet, a hybrid of Mediterranean and Japanese diets, reduces the risk of various diseases by suppressing chronic inflammation. This nutritional intervention prevents ME-BYO and is beneficial for healthy longevity. Hence, a Mediterranean-styled Japanese diet might be helpful for healthy longevity in Japan and around the world., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Paleotsunami studies along the Pacific coast of Tohoku, northern Japan, have been considerably developed recently, particularly after the massive impact of the 2011 Tohoku-oki tsunami. Nevertheless, in the southernmost Shimokita Peninsula, studies pertaining to paleotsunami are underdeveloped, leading to a vague understanding of the tsunamigenic sources northward of the Tohoku region, along with incomplete hazard evaluation. Paleotsunami deposits in Shimokita can be related not only to the Japan Trench along the Sanriku coast but also to the Kuril trench along the Pacific coast of Hokkaido. In this study, we unveiled the paleotsunami history of Hachinohe in northern Tohoku. Using a combination of sedimentological, geochemical, paleontological, and mineralogical proxies, we characterized seven sand layers that dated from ca. 2700 to ca. 5500 yr BP based on radiocarbon (14C) ages as event deposits of marine origin. Sedimentological and paleontological evidence coupled with ground-penetrating radar imagery revealed a marsh environment comprising successive extinct ponds, controlling the depositional environment. Numerical modeling ruled out the possibility of storms as genetic sources, leading to the conclusion that the presence of event deposits with marine sediments in the study area would be associated with tsunami inundation episodes. Based on 14C dating, the mean frequency of recurrence of tsunamis is estimated as 384 years (320–450 yr, 95% confidence interval) and a coefficient of variation of 0.78 (0.68–0.99, 95% confidence interval). The previously recorded limited paleotsunami evidence and absence of an estimated recurrence interval in the Shimokita Peninsula reaffirm the importance of Hachinohe as a tsunami record site for the activity of both trenches.
