The roles of psychological journals on promoting the reproducibility of psychological research are discussed. These roles contain requiring better statistical expressions, detailed description of research method, pre-registration, replication reports, improvement of peer-review, and accelerating open science. A case example of Japanese Journal of Personality is described.

The evolution of a heavy rainfall event occurred on 19 August 2014 in northern Taiwan is investigated with observed data and analyses from a newly-developed system named IBM_VDRAS, which is based on a four-dimensional Variational Doppler Radar Assimilation System (VDRAS) with the capability to assimilate radar observations and surface station data over a complex terrain by adopting the Immersed Boundary Method (IBM). This event possesses different precipitating processes and track from those frequently observed in that region. From the surface observations and the high spatiotemporal resolution analysis fields generated by IBM_VDRAS, it is found that the rainfall process started with the initiation of two individual convective cells triggered through the interaction between land-sea breeze and terrain in two different cities (Taoyuan and Taipei). The outflow of one of the convective cells developed in Taoyuan City at an earlier time merged with another convective system which grew in Taipei Basin, and provided favorable conditions to intensify the latter. The enhanced major convective cell moved into the Taipei City metropolitan area and produced 80 mm of precipitation within approximately 2.5 h. The kinematic, thermodynamic, and microphysical fields of the convective cells are analyzed in details to explain the mechanisms which helped to maintain the structure of the rainfall system. Sensitivity experiments of quantitative precipitation forecast (QPF) show that the terrains prevent the location of major rainfall from shifting outside of Taipei Basin. By assimilating surface data, the model can better predict the position of the rainfall.

The surface meteorological data in Japan, beginning around the 1880s, archived by the Japan Meteorological Agency are analyzed focusing on the long–term trends and variations in humidity and temperature. It is found that the annual–mean temperature trend exhibits statistically significant warming of 1.0-2.5°C century−1 for most stations, while the annual–mean relative humidity shows significantly decreasing trend of −2 % to −12 % century−1 for most stations with small seasonality. On the other hand, the annual–mean mixing ratio trend displays a different spatial distribution compared to the temperature or relative humidity trend. In this study, three types of trends exist: significantly positive and negative values, and virtually zero. Significantly negative trends of about −0.2 to −0.3 g kg−1 century−1 are located approximately in the Pacific side of Honshu from the middle Tohoku through Shikoku to the eastern Kyushu. Significantly positive trends of about 0.2 to 0.4 g kg−1 century−1 are observed over Hokkaido, the western Japan along Sea of Japan, the western Kyushu, and the remote islands including Okinawa. The overall pattern is similar for other seasons except for most of the remote islands in winter. Empirical orthogonal function (EOF) analysis indicates that the linear trends in the annual–mean temperature and relative humidity can be almost explained by the nearly uniform persistent warming and drying of EOF–1 components. On the other hand, for the annual–mean mixing ratio, EOF–2 is almost identical with the linear trend component, although the fraction of EOF–2 (14 %) is much smaller than that of EOF–1 (49 %). In recent years from 1960 to 2018 the mixing ratio and temperature trends are very different from those in the longer period from the 1880s. The mixing ratio trend and the temperature trend increase on average from 0.0 to 0.5 g kg−1 century−1 and from 1.5°C to 2.5°C century−1, respectively.

The purpose of the present study was to examine regions of the body affected by Kansetsu-waza. The participants were 22 college and high school judo players. They were requested to point out the most painful region for each Kansetsu-waza technique. For analysis,28 techniques were chosen from 9 kinds of Kansetsu-waza. The binominal test and the chi square test were conducted. The results demonstrated that the elbow was the most painful region for 16 techniques and the shoulder for 8 techniques. This finding suggests that some Kansetsu-waza, which was Udegarami, Udehishigi-hizagatame, and Udehishigi-sankakugatame, has both the technique affecting the elbow and that affecting the shoulder. From Uke arm movement,28 techniques can be classified into three broad types: extension, twist with internal rotation, and twist with external rotation. Chi square tests indicated that the elbow was the most painful region for extension techniques, and that the shoulder was the most painful region for twisting techniques with either internal or external rotation. In relation to refereeing rules, Kansetsu-waza application is forbidden for any joint other than the elbow, however this study indicated that some Kansetsu-waza techniques allowed in the competition affect the shoulder. These findings suggest that refereeing rules for Kansetsu-waza are not necessarily based on real-world experience and that there is room for improving application of these rules.

People feel uncomfortable when someone else comes spatially near and thus encroaches on their personal space (PS). Although many social psychologists have explored characteristics of PS of/between/among individuals so far, there is currently no empirical research on whether the PS of individuals expands into space surrounding their belongings (or objects) that are away from their body. This study measured the spatial distance between bags which participants and confederates left behind, and thus demonstrated that the distance between bags was modulated in response to the interpersonal relationship of their owners. The present study suggests new evidence for expansive PS, which is the concept that an individual’s PS expands into space surrounding his/her belongings.

<p>This study attempted to replicate Kamise, Hori, and Okamoto's (2010) survey on perceived occupational stigma among Japanese workers by conducting a survey with employees in a <i>host club</i>—a male cabaret club—in the Kansai region, Japan, to investigate their perceived occupational stigma, coping strategies, occupational self-esteem, and egalitarian sex-role attitudes. The results showed that host-club employees perceived extreme occupational stigma, where novices, part-time workers, and those with fewer work assignments showed higher levels of perceived stigma. Regarding coping strategies, attribution of discrimination and disengagement were used frequently, while valuing and group identification were used only rarely. Structural equation modeling showed that group identification positively enhanced occupational self-esteem. However, contrary to previous research, individuals who perceived more stereotyping rarely used group identification. Stigma awareness facilitated attribution of discrimination, resulting in lowered occupational self-esteem, and egalitarian sex-role attitude significantly influenced valuing and attribution of discrimination.</p>

イネばか苗病の発生源から異なる距離にある水田で採取した種籾を翌年播種し,本病の発病苗率を調査 した.その結果,発生源からの距離に比例して発病は少なくなり,50m~100m 以上離れると発病苗率は急激に低くなった.このことから,発生源から少なくとも100m 以遠では,ばか苗病菌の分生子の飛散は少なく,保菌籾率に及ぼす影響は小さいと考えられた.この結果を参考にして,北海道では,出穂後の採種ほ審査時に,採種ほの周辺ほ場にばか苗病発病株があった場合,その株から100mの範囲内の採種ほ内の株からは採種しないこととした.また,採種ほの周辺ほ場でばか苗病の発生程度が少発生以上認められる場合は,採種ほに最も近い発病株から200mの範囲内の採種ほ内の株からも採種しないこととした.
