Abstract: Although administrative bodies such as community health centers have implemented various awareness campaigns to promote community understanding of mental health and to reduce the stigma associated with mental illness and disorder, there have been few reports that have quantitatively analyzed the effects of these campaigns in Japan. Therefore, this study was conducted for the purpose of developing the evaluative “Mental Illness and Disorder Understanding Scale (MIDUS)” for awareness campaigns and assessing its reliability and validity. A survey was conducted on 1 004 community residents using a self‐administered questionnaire. An assessment of the reliability and validity of the scale was then conducted. The Cronbach a coefficient of the MIDUS was 0.78, thus indicating adequate reliability. Factor analysis of the MIDUS revealed three factors: “Treatability of illness”, “Efficacy of medication” and “Social recognition of illness”. In addition, a significant correlation was observed between the MIDUS and existing scales, and fixed criterion‐based validity was demonstrated. The MIDUS utilizes items worded in the form of affirmative expressions so as to avoid promoting new bias. It was confirmed to be both reliable and valid, thereby suggesting its usefulness as an evaluative scale of awareness campaigns. 相似文献

This paper concludes our comprehensive study on point estimation of model parameters of a gamma distribution from a second-order decision theoretic point of view. It should be noted that efficient estimation of gamma model parameters for samples ‘not large’ is a challenging task since the exact sampling distributions of the maximum likelihood estimators and its variants are not known. Estimation of a gamma scale parameter has received less attention from the earlier researchers compared to shape parameter estimation. What we have observed here is that improved estimation of the shape parameter does not necessarily lead to improved scale estimation if a natural moment condition (which is also the maximum likelihood restriction) is satisfied. Therefore, this work deals with the gamma scale parameter estimation as a separate new problem, not as a by-product of the shape parameter estimation, and studies several estimators in terms of second-order risk. 相似文献

Kernel discriminant analysis translates the original classification problem into feature space and solves the problem with dimension and sample size interchanged. In high‐dimension low sample size (HDLSS) settings, this reduces the ‘dimension’ to that of the sample size. For HDLSS two‐class problems we modify Mika's kernel Fisher discriminant function which – in general – remains ill‐posed even in a kernel setting; see Mika et al. (1999). We propose a kernel naive Bayes discriminant function and its smoothed version, using first‐ and second‐degree polynomial kernels. For fixed sample size and increasing dimension, we present asymptotic expressions for the kernel discriminant functions, discriminant directions and for the error probability of our kernel discriminant functions. The theoretical calculations are complemented by simulations which show the convergence of the estimators to the population quantities as the dimension grows. We illustrate the performance of the new discriminant rules, which are easy to implement, on real HDLSS data. For such data, our results clearly demonstrate the superior performance of the new discriminant rules, and especially their smoothed versions, over Mika's kernel Fisher version, and typically also over the commonly used naive Bayes discriminant rule. 相似文献

In the current polarizing political climate, what constitutes just has become increasingly questioned and debated in the public arena. Tyrants seem everywhere to shape people's understanding of who belongs in communities and nation-states and, therefore, who should be given a voice and what should be valued. This paper unpacks the mechanisms of tyranny and the pursuit of justice in the global agri-food system. The first section discusses justice and tyranny as sociological concepts and practice, followed by the second section that examins two types of tyrannies in the globalized agri-food system: neoliberal capitalism and community. I argue that neoliberal capitalism and community are the logics for organizing social relations and the sites of enacting tyrannies and justice. Third, I argue that in the tension between capitalism and community in achieving justice, rural becomes critical both theoretically and empirically for understanding the current transformations and the future challenges for transforming agri-food systems. Finally, the paper concludes with possible contributions of rural sociological imaginations to shaping the discourse of justice and explore the process of justice. 相似文献

Background
A low urine pH is a characteristic metabolic feature of metabolic syndrome and type 2 diabetes. The purpose of the current study was to investigate the effects of a 12-week home-based bench step exercise on the urine pH status of elderly female subjects.Methods
The current study is a secondary analysis of a randomized controlled trial (RCT) in which 59 postmenopausal female subjects were randomized to either the exercise group (n?=?29) or the control group (n?=?30). The subjects in the exercise group were instructed to perform home-based exercises using a bench step at the anaerobic threshold (AT), with a goal of performing ≥140 min/week at home for 12 weeks. The subjects in the control group were instructed to not change their normal lifestyle. Urine was collected after overnight fasting, and the urine pH was measured using a urinary test strip. The inter-group-differences at baseline and the pre-post changes within groups were assessed using the Mann-Whitney U test and Wilcoxon’s signed-rank test, respectively. Additionally, the difference in the post-intervention urine pH levels of the two groups, adjusted for the pre-intervention values (the estimated effect size) and the precision (95% confidence intervals) were investigated using an analysis of covariance.Results
The pre-post comparison of the urine pH data using Wilcoxon’s signed-rank test showed a significant increase in the urine pH levels of the exercise group (p?<?0.05); there was no significant change in the urine pH levels of the control group. However, the estimated effect size (0.15) was small and the confidence interval straddled 0 (?0.25–0.55).Conclusions
Based on the results of the current secondary analysis of an RCT, we could not clearly conclude that exercise has a beneficial effect on the urine pH. Further well-designed RCTs should be conducted to determine whether aerobic exercise is truly able to ameliorate urine acidification.Trial registration
The study was retrospectively registered in the University Hospital Medical Information Network (UMIN) as “Effect of step exercise on aerobic fitness and progression of atherosclerosis in the elderly” under the registration number UMIN 000026743 (the date of registration: March 28, 2017).6.
Charrettes have become popular in the urban design field, especially for use among multidisciplinary teams of professionals and non-professional community stakeholders seeking to incorporate a rich array of expertise in short visioning activities. Geographic Information Systems are among the technologies with potential to provide sophisticated spatial information to charrette participants efficiently. This article reports on a charrette carried out jointly by teams from Kobe University and the University of Washington, Seattle, USA, using GIS to inform urban design in three neighborhoods affected by the Great Hanshin–Awaji Earthquake of 1995 in Kobe, Japan. The article describes the charrette itself, and discusses the utility of GIS, given the challenges of disaster recovery in a context of undeveloped institutions for public participation, and with participants of different linguistic and educational backgrounds. In combination with electronically storable drawing technology, GIS proved useful in enlarging the multidisciplinary and cross-cultural reach of urban design; in incorporating new layers of pre-prepared expert data, and in combining such data with dynamically-generated “advice maps” and design ideas. For GIS-based charrettes to become more widely useful in community-scale design in Japan, however, additional property-scale data need to be available. 相似文献

Infants' Processing of Featural and Configural Information in the Upper and Lower Halves of the Face
Three‐ to 4‐month‐old and 6‐ to 7‐month‐old infants were administered an infant version of the Face Dimensions Test that has been used with adults (e.g., Bukach, Le Grand, Kaiser, Bub, & Tanaka, 2008). Infants were familiarized with a photograph of a woman's face and then tested with the familiar face paired with a face differing in the (a) distance separating the eyes (a configural/eyes change), (b) distance between the nose and mouth (configural/mouth change), (c) size of the eyes (featural/eyes change), and (d) size of the mouth (featural/mouth change). Infants were shown to be more sensitive to (a) configural than featural change, and (b) change around the eyes versus the mouth. Implications for the development of face processing are discussed. 相似文献

Influence functions are derived for the parameters in covariance structure analysis, where the parameters are estimated by minimizing a discrepancy function between the assumed covariance matrix and the sample covariance matrix. The case of confirmatory factor analysis is studied precisely with a numerical example. Comparing with a general procedure called one-step estimation, the proposed procedure has two advantages:1) computing cost is cheaper, 2) the property that arbitrary influence can be decomposed into a fi-nite number of components discussed by Tanaka and Castano-Tostado(1990) can be used for efficient computing and the characterization of a covariance structure model from the sensitivity perspective. A numerical comparison is made among the confirmatory factor analysis and some procedures of ex-ploratory factor analysis by using the decomposition mentioned above. 相似文献

In this paper we discuss some distributional properties of quadratic functionals of the ordinary and fractional Brownian motions (fBms). As far as the ordinary Brownian motion (Bm) is concerned, those properties have been established extensively. A transition from the Bm to the fBm is not straightforward. Some difficulties associated with dealing with the fBm are explained, and a way to solving the problem is indicated, and some conjectures are given. 相似文献
