In Japan, accurately assessing and targeting gambling urges is important for the treatment of gambling disorder because people are constantly exposed to external triggers that elicit gambling urges. However, a valid measure that assesses gambling urges has not been adequately established. Therefore, the purpose of this study was to examine the psychometric properties of the Japanese version of the Gambling Urge Scale (GUS-J), which is a well-known valid 6-item instrument in English-speaking countries. Two hundred and thirty-nine participants completed questionnaires, 86 of which met the criteria for a probable gambling disorder. As with the original GUS, the GUS-J was demonstrated to be a one-factor model that accounted for 63.82% of the total item variance, with all items demonstrating loadings of .40 or higher. With regard to reliability, the GUS-J showed good internal consistency (α = .88). Furthermore, validity based on evidence of relationships with other variables, especially convergent and concurrent validity of the GUS-J, were supported by several analyses that examined hypotheses based on previous findings. In conclusion, this study showed that the GUS-J has good psychometric properties as an assessment tool for gambling urges in Japanese people and it will be useful for future clinical practice and research. 相似文献

Within a population of the web-building spiderAgelena limbata, the weight of the first instar nymphs ranged from 1.187 to 6.559 mg. Both intraclutch and interclutch variation were recorded.
The mean weights were different among clutches and the coefficients of variation within a clutch ranged from 3.3 to 29.2%.
Variation in the nymphal weight was certainly derived from variation in the egg weight because there was a high correlation
between the two weights. Factors affecting interclutch variation in nymphal weight were examined by multiple regression analysis.
Nymphal weight was positively correlated with the body size and food conditions of female parents, and negatively correlated
with the clutch size. Among these three factors, the food conditions of female parents had the largest apparent effect on
the interclutch variation. The results suggest that females with larger body size and more food produce larger offspring,
and that there is a trade-off between offspring size and clutch size. Heavier nymphs had larger body size (carapace width)
and may have larger energy reserves. Heavier nymphs survived experimental starvation for a significantly longer period. 相似文献

Wing shedding or de-alation is a common phenomenon among crickets. Its significance and effects on other traits were examined
based on the results from experiments using artifical or natural de-alation. Artificial de-alation at adult emergence induces
rapid egg production and flight muscle histolysis in several species examined. However, natural de-alation does not always
shorten the pre-ovipositional period because it does not occur immediately after adult emergence and because oviposition starts
before de-alation. In some cases, naturally de-alated females produce more eggs than to intact females during early adult
life, but peak ovipositing activity occurs before de-alation. Therefore, retention of the hindwings does not suppress high
ovipositing activity in such cases. It appears that de-alation is a result rather than a causal factor in ending migration.
Ovarian development and flight muscle histolysis, which can be stimulated by de-alation, are controlled by the jevenile hormone,
but the mechanism inducing de-alation remains unknown. The possible factors leading to the evolution of de-alation are discussed. 相似文献

A simple quantitative genetic model is proposed to explain the observed genetic correlation structure of a bruchid beetleCallosobruchus chinensis in terms of two underlying variables: the resource acquisition and the resource allocation. Heritabilities and genetic correlations
among age-specific, fecundities are regarded as consequences of genetic variations of the two variables. Genetic correlations
are predominantly positive in both predictions and observations. Nonetheless, comparison between observed and predicted values
in heritabilities, genetic correlations, and genetic principal components suggested significant genetic variances both of
the resource allocation and the resource acquisition. The prediction of the model is discussed in relation, to experimental
tests of trade-off in life history evolution. 相似文献

The present study examines differences in systems development and difficulties in implementing procedures for elder abuse prevention in 1,119 private and 606 public community general support centers under the public long-term care insurance program in Japan. The private community general support centers showed more difficulty implementing procedures than the public community general support centers. Controlling for the type of municipality, progress in systems development did not differ between the private and public community general support centers. Further research should examine how the characteristics of municipal governments are related to systems development in community general support centers. 相似文献

Consider an estimation problem under the LINEX loss function in one-parameter non-regular distributions where the endpoint of the support depends on an unknown parameter. The purpose of this paper is to give sufficient conditions for a generalized Bayes estimator of a parametric function to be admissible. Also, it is shown that the main result in this paper is an extension of the quadratic loss case. Some examples are given. 相似文献

中国固有法秩序与西方近代法秩序 总被引:1,自引:0,他引:1
西方法秩序的形成是以个体为出发点的,然后再考虑保护这些个体利益的社会组织,即个体出发型;而中国法秩序的构思是首先考虑人们的整体共存,然后再给各个主体划分相应的利益,即整体出发型。西方法秩序是被现实的世界和法的世界双重化后,再由法的世界统治现实世界;在传统中国,法的世界和现实的世界之间没有媒介,二者是合为一体的。近代中国引进的西方"法制度",不是一种法秩序,而是一种工具或者社会装置。 相似文献

Background
The purposes of this study were to identify 1) the feasibility of a novel exercise protocol (elderly Japanese male version of high-intensity interval aerobic training: EJ-HIAT) and 2) its preliminary data (%V?O2peak, rating of perceived exertion) in comparison with traditional moderate-intensity continuous aerobic training (MICT).Results
Twenty-one sedentary elderly men, aged 60–69 years, performed two exercise protocols: EJ-HIAT, consisting of 3 sets of 2?3-min cycling at 75?85%V?O2peak with 1??2-min active rests at 50%V?O2peak between sets, and MICT, consisting of 40-min cycling at 65%V?O2peak. The completion rate, defined as the rate of participants who 1) did not demand withdrawal, 2) were not interrupted by the tester, and 3) did not change the workload during either exercise protocol, of EJ-HIAT was similar to that of MICT (EJ-HIAT: 100%, MICT: 95.2%). Maximal perceived exertion ratings assessed by Borg scale were also similar between EJ-HIAT and MICT. However, objectively measured maximal intensity assessed by %V?O2peak was higher for EJ-HIAT than for MICT (EJ-HIAT: 86.0 ± 5.6%, MICT: 67.1 ± 6.4%).Conclusion
These results suggested that EJ-HIAT has good feasibility and perceived exertion similar to MICT despite having higher objectively measured intensity than MICT. An intervention aimed as identifying the effects of EJ-HIAT on exercise tolerance should be performed in the future.Trial registration

We examine whether there are any systematic gender differences in voluntary public goods provision experiments under the two different framing conditions—the positive-frame and the negative-frame. We find that: (1) there are significant framing effects in their contribution rates for both men and women; (2) there is no significant gender difference in their contribution rates under the positive-frame and (3) there is a significant gender difference in their contribution rates under the negative-frame. In fact, women are more generous in their contribution than men under the negative-frame. 相似文献
