Object-Spatial Imagery Types of Japanese College Students  [PDF]
Masahiro Kawahara, Kazuo Matsuoka
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.43024

This study investigated the object-spatial imagery types found among Japanese college students. First, we examined the descriptive statistics of the Japanese version of the Object-Spatial Imagery Questionnaire object-spatial imagery scales, which measure respondents’ tendencies with respect to object-spatial imagery types. Although the means of these subscales were lower than those of the original versions, the raw score distributions and gender differences were similar to those obtained using the original version. Additionally, we compared imagery types among students in seven different academic departments. Specifically, the results showed specific patterns of imagery type among students in each department, indicating that the object-spatial imagery type model is applicable to Japanese college students and that individual imagery type data would be helpful for career guidance.

Abstract: We report the discovery of a cyclotron resonance scattering feature (CRSF) in the X-ray spectrum of GX 304-1, obtained by RXTE and Suzaku during major outbursts detected by MAXI in 2010. The peak intensity in August reached 600 mCrab in the 2-20 keV band, which is the highest ever observed from this source. The RXTE observations on more than twenty occasions and one Suzaku observation revealed a spectral absorption feature at around 54 keV, which is the first CRSF detection from this source. The estimated strength of surface magnetic field, $4.7 \times 10^{12}$ G, is one of the highest among binary X-ray pulsars from which CRSFs have ever been detected. The RXTE spectra taken during the August outburst also suggest that the CRSF energy changed over 50-54 keV, possibly in a positive correlation with the X-ray flux. The behavior is qualitatively similar to that observed from Her X-1 on long time scales, or from A 0535+26, but different from the negative correlation observed from 4U 0115+63 and X 0331+53.

Abstract: Over the 3-year active period from 2008 September to 2011 November, the outburst behavior of the Be/X-ray binary A 0535+26 was continuously monitored with the MAXI/GSC and the Swift/BAT. The source exhibited nine outbursts, every binary revolution of 111.1 days, of which two are categorized into the giant (type-II) outbursts. The recurrence period of these outbursts is found to be $\sim115$ days, significantly longer than the orbital period of 111.1 days. With the MAXI/GSC, a low-level active period, or a "precursor", was detected prior to at least four giant outbursts. The precursor recurrence period agrees with that of the giant outbursts. The period difference of the giant outbursts from the orbital period is possibly related with some structures in the circumstellar disc formed around the Be companion. Two scenarios, one based on a one-armed disc structure and the other a Be-disc precession, are discussed.

Abstract: We cross-sectionally examined the degrees of airway sensitivity, the point where resistance started to increase, and reactivity, the slope of the methacholine-resistance curve, and the appearance of cough and wheezes in steroid-na?ve adult patients with classic asthma (n = 58) or CVA (n = 55) while they were continuously inhaling methacholine during simultaneous measurement of respiratory resistance.Patients with CVA were less sensitive and less reactive to inhaled methacholine and wheezed less frequently but coughed more frequently during methacholine-induced bronchoconstriction than did patients with classic asthma. Multivariate analysis revealed that airway hypersensitivity and lower baseline FEV1/FVC were associated with the appearance of wheezes, whereas a diagnosis of CVA was associated with coughing.There are mechanistic and phenotypic differences between CVA and classic asthma during methacholine inhalation. Frequent coughing during bronchoconstriction may be a distinctive feature of CVA.Patients with cough variant asthma (CVA) present with a chronic cough as the sole symptom that responds to bronchodilator treatment and show airway hyperresponsiveness (AHR). CVA, one of the most common causes of chronic cough [1-4], is considered a precursor [5-9] and a variant form of classic asthma with typical symptoms of wheezing and dyspnea [5]. Several studies have examined mechanistic differences between CVA and classic asthma. Airway sensitivity, a component of airway responsiveness that is defined as the inflection point where respiratory resistance (Rrs) starts to increase, did not differ between patients with CVA and those with classic asthma in a few small studies [10,11]. In contrast, airway reactivity, another component of airway responsiveness expressed as the slope of the dose-response curve, is attenuated in children with CVA as compared with those with classic asthma [12]. In adults with CVA, however, no study has separately examined airway sensitivity and

Abstract: We have analyzed prevalence and clinical characteristics of patients who were diagnosed as having GOR-CC among adult patients with chronic cough (≥ 8 weeks) who visited our asthma and cough clinic over a period of 19 months. Diagnosis of GOR-CC was based on the response of coughing to a proton-pump inhibitor (lansoprazole?) and/or positive results of 24 h ambulatory esophageal pH monitoring. Laryngeal involvement was based on symptoms or objective diagnosis by specialists.GOR-associated chronic cough was diagnosed in 7.1% (8 of 112) of chronic cough patients. In addition to the demographic data which were consistent with the characteristics of patients with GOR-CC in the Western populations, including gender (6 females), age (mean ± SE, 56.9 ± 5.8 years), duration of cough (9.9 ± 3.3 months), lack of gastrointestinal symptoms (3 of 8) and complication with other causes of cough (5 of 8), we found the standard range of body mass index (23.9 ± 1.5 kg/m2) and high incidence of concomitant reflux laryngitis (5 of 8) in the present 8 patients. Among 4 patients who could stop treatment with temporal resolution of cough, cough recurred in 3 patients, 1 week to 8 months after the discontinuation.In conclusion, GOR-CC is a less frequent cause of chronic cough in Japan than in Western countries. Signs or symptoms of laryngitis may be important as clues to suspicion of GOR-CC.Despite the established evidence that gastro-oesophageal reflux (GOR) causes 10 to 40% of chronic cough [1], and the prevalence of GOR-associated chronic cough (GOR-CC) is increasing in the Western populations [2], this condition has been rarely reported in Japan and its clinical manifestation is not well characterized. Only one case among 37 patients with chronic dry cough was diagnosed as having GOR-CC in our previous study carried out in the mid '90s [3]. Our present study is concerned with the rising number of cases of GOR-CC in Japan and of concomitant reflux laryngitis which is another major extra-o

Abstract: The neutron-star Low-Mass X-ray Binary Aquila X-1 was observed by Suzaku for seven times, from 2007 September 28 to October 30. The observations successfully traced an outburst decay in which the source luminosity decreased almost monotonically from $\sim 10^{37}$ erg s$^{-1}$ to $\sim 10^{34}$ erg s$^{-1}$, by $\sim 3$ orders of magnitude. To investigate luminosity-dependent changes in the accretion geometry, five of the seven data sets with a typical exposure of $\sim 18$ ks each were analyzed; the other two were utilized in a previous work \citep{Sakurai2012}. The source was detected up to 100 keV in the 2nd to the 4th observations, to 40 keV in the 5th, and to 10 keV on the last two occasions. All spectra were reproduced successfully by Comptonized blackbody model with relatively high ($\gtrsim 2.0$) optical depths, plus an additional softer optically-thick component. The faintest three spectra were reproduced alternatively by a single Comptonized blackbody model with a relatively low ($\lesssim 0.8$) optical depth. The estimated radius of the blackbody emission, including seed photons for the Comptonization, was $10 \pm 2$ km at a 0.8--100 keV luminosity of $2.4\times 10^{36}$ erg s$^{-1}$ (the 2nd to the 4th observations). In contrast, it decreased to $7 \pm 1$ km and further to $3 \pm 1$ km, at a luminosity of $(4.8-5.2)\times 10^{35}$ erg s$^{-1}$ (the 5th observation) and $\sim 2\times 10^{34}$ erg s$^{-1}$ (the 6th and 7th), respectively, regardless of the above model ambiguity. This can be taken as evidence for the emergence of a weak magnetosphere of the neutron star.

Abstract: Motor symptoms are cardinal clinical features of Parkinson’s disease (PD). Progress in drug therapy and rehabilitation has been presenting beneficial effect for motor symptoms. However, non-motor symptoms and signs in PD have been accumulated growing attentions and its amelioration may also give beneficial effect for PD patients’ and their care givers’ quality of life. In this mini-review, I overviewed non-motor symptoms and signs in PD.
A Revival of Little Black Sambo in Japan  [PDF]

Advances in Literary Study (ALS) , 2014, DOI: 10.4236/als.2014.21003

In the late 1980s, a popular children’s book “Little Black Sambo”(hereafter,LBS) disappeared from all bookstores in Japan.The book was alleged to have racist characteristics such as the name of the boy, the way the illustrations caricatured blacks, etc. Mori (1997) revised the original story by changing the protagonist from a black boy to a black Labrador puppy, with eliminating the word “Sambo”,which had a historically pejorative connotation in the US. Mori (2005) conducted an experiment to compare the entertainment value of the two versions of LBS using four-year-old children and found no difference. Mori (2005) also casted a suspicion that the real reason why the book was withdrawnin Japan was a matter of piracy rather than racism. All Japanese publishers at that time had not properly obtained the copyright. Nowadays there are several versions of LBS available in bookstores all over Japan.

Getting Rid of the Horizontal-to-Vertical Strategy: A Case Report of a Japanese Research Psychologist  [PDF]

Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.24040
Abstract: Most Japanese research psychologists have used “Horizontal-to-Vertical Conversion Strategy” for their research, simply replicating experimental studies published in Western journals with Japanese participants and publishing papers only in Japanese (the traditional orthography of the Japanese language is vertical). This short article criticized this prevailing research strategy among Japanese psychologists and reported a series of studies resulted from an invention of new experimental procedure. It showed an example of a Japanese researcher who had got rid of the inadequate approach by inventing a new experimental method. It also aimed to encourage Japanese psychologists to conduct innovative research and publish their studies in English journals.

We examined whether Japanese people, 47 junior high school students, 49 undergraduates, and 52 older adults, possessed negative attitudes against blacks and the picture book Little Black Sambo. We assessed the implicit attitude toward the target word pairs, “black/white” and “Sambo/Heidi,” by utilizing a paper-based Implicit Association Test and found that both black and Sambo were associated more negatively than white and Heidi. However, the implicit attitudes assessed with a single-target IAT showed that 67 Japanese students showed positive implicit scores for blacks but with smaller valences. A post hoc analysis revealed that the reading experience of Little Black Sambo did not show a significant difference between the implicit attitudes of those who had and had not read the book.
