Japan's “New Homeless”

Since the mid-1990s, homelessness has become a major issue of public discussion in Japan, and is often viewed as a new social problem facing Japanese society. The issue of homelessness contrasts images of the absence of poverty and homelessness in postwar Japan, often explained based on the unique features of Japanese-style employment and welfare, containing poverty and unemployment. This paper contrasts these views with a perspective on the continuity of poverty, and homelessness in postwar Japan. Specifically, I discuss the characteristics of homelessness in Tokyo, how they relate to the structure of the economy and employment practices, and how the problems of today's homeless are accommodated in the welfare system. I argue that the homeless cast light on patterns of loss of employment, housing, and means of subsistence, characteristic to Japan's economy and welfare system, and contribute to a new understanding of the dynamics of poverty in contemporary Japan.

Hesitant Madams in a Global City: Japanese Expat Wives and their Global Householding in Hong Kong

Care work, once a sanctioned labor of love, is increasingly commodified in transnational contexts. The picture of migrant women shouldering the housework and child care of local professonal women may seem like a mutually beneficial arrangement—matching the “needs” of the haves and have-nots—, but the global care chain ultimately works to maintain the traditional gendered division of labor as well as global inequality. To this trend of globalization of care work, Japan has been an exception; however, how much longer it will be so is now in a question, as the government paves the way for importing domestic labor from abroad. This article focuses on Japanese expat wives in Hong Kong in order to locate Japanese women vis-à-vis the global care chain. The narrative analysis on how they decide whether to hire a domestic worker in their home away from home highlights the sociopolitical nature of their supposedly private choices. Some drew on cultural ideal of wifehood and motherhood to rationalize their choice while others referred to racialized or even overtly racist and classist images of foreign domestic workers. A few women spoke against the system itself, showing awareness of its inherent social injustice. All such narratives are never purely personal; their decisions and the rationalization behind them sustain the prevailing discourses of gender, race, ethnicity, culture, and class, which, in turn, envelop their attempts at global householding.     

Optimal design of the adaptive exponentially weighted moving average control chart over a range of mean shifts

The adaptive exponentially weighted moving average (AEWMA) control chart is a smooth combination of the Shewhart and exponentially weighted moving average (EWMA) control charts. This chart was proposed by Cappizzi and Masarotto (2003) to achieve a reasonable performance for both small and large shifts. Cappizzi and Masarotto (2003) used a pair of shifts in designing their control chart. In this study, however, the process mean shift is considered as a random variable with a certain probability distribution and the AEWMA control chart is optimized for a wide range of mean shifts according to that probability distribution and not just for a pair of shifts. Using the Markov chain technique, the results show that the new optimization design can improve the performance of the AEWMA control chart from an overall point of view relative to the various designs presented by Cappizzi and Masarotto (2003). Optimal design parameters that achieve the desired in-control average run length (ARL) are computed in several cases and formulas used to find approximately their values are given. Using these formulas, the practitioner can compute the optimal design parameters corresponding to any desired in-control ARL without the need to apply the optimization procedure. The results obtained by these formulas are very promising and would particularly facilitate the design of the AEWMA control chart for any in-control ARL value.     

Feminist Heuristics: Transforming the Foundation of Food Quality and Safety Assurance Systems*

Food safety and quality assurance systems have emerged as a key mechanism of food governance in recent years and are also popular among alternative agrofood movements, such as the organic and fair trade movements. Rural sociologists have identified many problems with existing systems, including corporate cooptation, the marginalization of small producers, and the depoliticization of consumer consciousness. Tackling these problems requires an epistemological shift. This article argues that the existing systems are based on positivist epistemology and calls for a feminist intervention. To show a concrete example of a feminist departure from the conventional assurance systems, I look at the case of a Japanese women's food cooperative and analyze its unique system, comparing it to its conventional counterpart, Hazard Analysis and Critical Control Points (HACCP). Feminist epistemology can change assurance systems from being closed, nondiscriminatory, and technical to being participatory, differentiated, and normative.     

A Comparison of the Performance of Phase II Simple Linear Profile Control Charts when Parameters are Estimated

The standard deviation of the average run length (SDARL) is an important performance metric in studying the performance of control charts with estimated in-control parameters. Only a few studies in the literature, however, have considered this measure when evaluating control chart performance. The current study aims at comparing the in-control performance of three phase II simple linear profile monitoring approaches; namely, those of Kang and Albin (2000), Kim et al. (2003), and Mahmoud et al. (2010). The comparison is performed under the assumption of estimated parameters using the SDARL metric. In general, the simulation results of the current study show that the method of Kim et al. (2003) has better overall statistical performance than the competing methods in terms of SDARL values. Some of the recommended approaches based solely on the usual average run length properties can have poor SDARL performance.     

Pitch and Communicative Intent in Mother's Speech: Adjustments for Age and Sex in the First Year

This study investigated pitch and communicative intent in mothers' infant‐directed speech spoken to their infants at birth, 3, 6, 9, and 12 months. Audio recordings of mothers (6 with female, and 6 with male infants) talking to another adult and to their infant at 5 ages were low‐pass filtered and rated by 60 adults on 5 scales (Positive or Negative Affect, Express Affection, Encourage Attention, Comfort or Soothe, and Direct Behavior). Mean fundamental frequency (F₀) and pitch range of utterances were also measured. Utterances associated with positive affect tend to peak at 6 and 12 months, whereas more directive utterances peaked at 9 months. Mean F₀ followed the age trend for affective utterances, and pitch range followed the trend for directive utterances. The results suggest mother speech patterns reflect, complement, and perhaps facilitate infant development.     

A Combined Nonlinear Programming Model and Kibria Method for Choosing Ridge Parameter Regression

Ridge regression solves multicollinearity problems by introducing a biasing parameter that is called ridge parameter; it shrinks the estimates as well as their standard errors in order to reach acceptable results. Many methods are available for estimating a ridge parameter. This article has considered some of these methods and also proposed a combined nonlinear programming model and Kibria method. A simulation study has been made to evaluate the performance of the proposed estimators based on the minimum mean squared error criterion. The simulation study indicates that under certain conditions the proposed estimators outperform the least squares (LS) estimators and other popular existing estimators. Moreover, the new proposed model is applied on dataset that suffers also from the presence of heteroscedastic errors.     

Photographs of disasters. An ethnomethodological approach

The essay analyses the photographs produced and circulated during the March 2011 tsunami and earthquake disaster in Japan, which show destroyed buildings, flooded landscapes, desperate people. Disaster destroys existing order. On first sight, the photographs of disaster depict this dissolution of order. The empirical analysis shows that the disastrousness of disaster is (also) created through the pictures of the disasters. The paper discusses why and in what way certain pictures reveal themselves to be iconographic of disaster and how they enter the visual memory as its representative. To achieve this, the study will invoke ethnomethodology. At the centre of the analysis is the question of the particular means with which these images illustrate the destructive force of the disasters and how pictures showing destruction and pain (‘pictures of pain’) turn into pictures effecting pain in the viewer (‘painful pictures’). The empirical study demonstrates: the photographs show the destruction of order; however, they do this in an orderly manner.
