The effect of exposure to a professor with a visible disability on students' attitudes toward disabilities

An exploratory study was conducted on a small convenience sample of undergraduate social work students. The Modified Issues in Disability Scale was used to collect data on attitudes toward disability. There was no statistically significant difference in the attitudes scores among students who had different levels of contact with persons with disabilities. There was, however, a statistically significant difference between students who had a professor with a disability and those who did not. The former had more positive attitudes toward disability. These findings suggest that schools of social work should recruit more professors with disabilities.     

Perceptions of child abuse: a comparison of three professional groups in Japan

Japan passed its Child Abuse Prevention Act on 20 November 2000. In these early years following the passage of this Act, it is especially important to attempt to define what constitutes child abuse. Definitions and practical responses may be coloured by perceptions of service providers, and since professional culture is believed to influence individuals, this study compared the perceptions of (a) social workers, (b) physicians, (c) lawyers, and (d) the general public. Results suggested less disagreement in perceptions than was anticipated. When differences were observed, they were correlated more frequently with age and gender rather than with profession.     

Large sample theory for a multivariate structural relationship with replication

For a multivariate structural relationship, where the replicated observations are available and the covariance matrix of the observational error is not restricted to diagonal, we consider the generalized least-squares estimators of the unknown structural parameters. The estimators are proved to be asymptotically normally distributed using the Liapunov central limit theorem under mild conditions on the incidental parameters. Their asymptotic covariance matrix is also derived.     

Social Work Development in Japan

With the enactment of the Certified Social Workers and Care Workers Act in 1987, Japanese social work would seem at last to have achieved social recognition and a secure position in Japanese society. However, when one examines the roles, working conditions, education and training of social workers, there are significant differences to be observed from the norms of western social work. In this paper the author sets out the unique characteristics of social work in Japan and reviews the pattern of its development in historical, cultural and political terms.     

The independent living movement in Asia: solidarity from Japan

Independent living movements of disabled people are emerging in Asian countries, supported by independent living centres (ILCs) in Japan. A study was conducted in Japan to explore the impact of the training program offered by Japanese ILCs to disabled people from other Asian countries. A sample of 35 people was selected by a snowballing method. The sample included former trainees from Asian countries and Japanese personnel from disability organizations involved with the training program. In‐depth interviews and a focus group were conducted to obtain information about the program, the experiences of the trainees and Japanese hosts and the budding independent living movement in Asia.     

Association of bioavailable estradiol levels and testosterone levels with serum albumin levels in elderly men

Estrogens are reported to be the essential sex steroid acting on some male physiological functions, and bioavailable estrogens comprise the free and albumin-bound fractions. Moreover, most of the bioavailable sex steroid is made up of albumin-bound fraction. We examined the age-related change in serum free, albumin-bound and bioavailable estradiol levels in comparison with each fraction of testosterone and its relationship with serum albumin level in elderly men. Albumin-bound as well as bioavailable estradiol levels declined with age, and their decreases were associated much more with the decrease of albumin level than the increase of sex-hormone binding globulin (SHBG) level in sixties and seventies, and similar results were recognized in the level of each fraction of testosterone, suggesting albumin levels have an important role for maintaining bioavailable sex steroid levels in males aged over sixty. Moreover, our study showed that SHBG levels associated inversely with bioavailable sex steroid levels particularly when serum albumin level was low. It seems likely that the decrease of bioavailable estradiol as well as testosterone is induced by the decrease of albumin-bound fractions in combination with the increase of SHBG-bound fractions in males aged over sixty, and that their physical characteristics of aging could be induced by the decrease of albumin-bound fractions caused by the decrease of serum albumin regardless of total sex steroid levels.     

Property Size and Land Cover Change in the Brazilian Amazon

This paper considers the size of a farmer’s property as a key variable influencing land cover and land cover change in rural areas of developing countries. Data from 126 rural familial properties in the region around the city of Santarém, Pará, in the Brazilian Amazon, indicate that property size is important for understanding the trajectories of land cover change. Past research has focused on the distinction between small family farms and large capitalized farms, arguing that family farmers have a higher deforestation intensity, or on estimating the strength of the effect of property size relative to economic or demographic factors. This paper shows that larger familial properties are able both to retain a larger area in forest and to have long enough cycles of use and fallow to allow previously used land to become forested again. Based on these analyses and discussion, we argue that land use and land cover research must consider property size as an organizing principle in order to better comprehend the reciprocal relationship between population and environment in frontier areas of the Brazilian Amazon and other rural landscapes.     

Expanding state space and extension of beliefs

This article provides a simple decision theoretic model in which elements of the world successively enter the decision maker??s scope and the state space expands over time, which is intended to be the closest correspondence to the standard subjective expected utility theory. We propose a dynamic consistency condition that after any expansion of the scope, the preference ranking should remain unchanged over acts to which the expansion is irrelevant. Together with other natural axioms, it characterizes a model in which the decision maker??s belief extends over time in order that the marginal distribution of the new belief induced over the old state space coincides with the old belief. It is extended to encompass both expansion of scope and learning events, and we characterize the model with an additional property that the decision maker??s belief updating follows Bayes?? rule when she learns events.     

The Use of Pitch Accent in Word–Object Association by Monolingual Japanese Infants

This study investigated the lexical use of Japanese pitch accent in Japanese‐learning infants. A word–object association task revealed that 18‐month‐old infants succeeded in learning the associations between two nonsense objects paired with two nonsense words minimally distinguished by pitch pattern (Experiment 1). In contrast, 14‐month‐old infants failed (Experiment 2). Eighteen‐month‐old infants succeeded even for sounds that contained only the prosodic information (Experiment 3). However, a subsequent experiment revealed that 14‐month‐old infants succeeded in an easier single word–object task using pitch contrast (Experiment 4). These findings indicate that pitch pattern information is robustly available to 18‐month‐old Japanese monolingual infants in a minimal pair word‐learning situation, but only partially accessible in the same context for 14‐month‐old infants.
