Yamato Transport Corporation recently entered the parcels business and has been very successful, taking the largest share of the market, in competition with the Japanese Post Office. By the use of a computerized information system, the company provides a rapid high quality service. Yamoto offers a pick up and delivery service. It uses retail stores for receiving the parcels and every driver has a small ‘point of sale’ terminal. The company has built its transportation network systematically, one step at a time. 相似文献

For square contingency tables that have nominal categories, Tomizawa considered two kinds of measure to represent the degree of departure from symmetry. This paper proposes a generalization of those measures. The proposed measure is expressed by using the average of the power divergence of Cressie and Read, or the average of the diversity index of Patil and Taillie. Special cases of the proposed measure include Tomizawa's measures. The proposed measure would be useful for comparing the degree of departure from symmetry in several tables. 相似文献

How does the development of collaborative research networks vary? This paper investigates how research networks have developed in the same technological fields in North America, Europe, and Asia. Exploring inter-organizational co-authored papers published in the Applied Physics Letters from 1975 to 1994, we first map the collaborative research networks and demonstrate that research networks were more developed in scale and scope in North America than in Europe and Asia in semiconductor laser technology. U.S. organizations played a nodal role in networking throughout this time period. Addressing how research networks were more developed in the U.S. than in Japan in particular, this paper concludes that engineer mobility, academic–industry relationships, and entrepreneurial startups were the key factors for the development of collaborative networks during the periods studied. 相似文献

Summary A population of the grey red-backed vole,Clethrionomys rufocanus bedfordiae, was investigated on a 1 ha control grid and a 1 ha grid on which the voles were fed within a 2.1 ha outdoor enclosure in
Hokkaido, Japan by live trapping from 1984 to 1986, for testing the Reproductive Suppression Model of Wasser and Barash (1983)-females
can optimize their lifetime reproductive success by suppressing reproduction when future conditions for the survival of offspring
are likely to be sufficiently better than present ones as to exceed the costs of the suppression itself. Age at the first
pregnancy more varied in a higher density population on the experimental grid and females could be classified into the early
and the late reproductive type in two generations (A: females born from February to June 1985; B: females born from September
to November 1985). Lifetime reproductive success (the number of pregnancies, the number of successful litters, and the number
of offspring) was not different between the early and the late reproducing females. The late reproducing females lived for
longer periods than the early reproducing females, so that the loss by delayed start of reproduction was compensated for by
a longer life span. Life span was not different between offspring of the early and the late reproducing females. These facts
supported the Reproductive Suppression Model. 相似文献

The natal dispersal distance of the grey-sided vole,Clethrionomys rufocanus (Sundevall), was measured in a large outdoor enclosure (2.1 ha) in Hokkaido, Japan. Voles in about half of the enclosure
(1 ha) were fed. Distance from the natal site to the site of reproduction was significantly greater in males (64.9 m) than
in females (35.3 m). In males, 24.8% settled within one home range length of their natal site and 49.6% settled further than
two range lengths from their natal site. In femles, the respective percentages were reversed: 51.2% and 22.0%. The timing
of large movements (≥50 m) was related to body mass in both sexes. The population density was always higher on the fed grid
than on the control grid, which resulted in the frequency of large movements being greater on the fed grid that on the control
grid. Thus, the percentage of voles performing a large movement was not different between the grids in both sexes. 相似文献

Clinical trials with event‐time outcomes as co‐primary contrasts are common in many areas such as infectious disease, oncology, and cardiovascular disease. We discuss methods for calculating the sample size for randomized superiority clinical trials with two correlated time‐to‐event outcomes as co‐primary contrasts when the time‐to‐event outcomes are exponentially distributed. The approach is simple and easily applied in practice. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Abstract The Great Hanshin-Awaji earthquake revealed the inadequacy of research in the area of information studies. There is a lack of research on the availability of information on daily life which could alleviate suffering during the reconstruction period. The purpose of this paper is to confirm whether residents receive sufficient information to assist them in making rational decisions during the Great Hanshin-Awaji Earthquake. Our research findings are as follows: (1) People's capacity to send information was very low early in the emergency period. (2) The channel of communication depended on whether people stayed in their own homes or lived elsewhere during the evacuation period. (3) The use of mass media by the aged (both in terms of receiving and sending information) was low. (4) The higher the damage to utilities, the higher was the levels of dissatisfaction with the existing means of information. Most people wished direct communications between the municipality and the victims. (5) Consummatory information on the actual situation was offered effectively by mass media in the stricken area. Similarly important information to support life in the stricken areas was offered by many volunteer groups. 相似文献

It is an undeniable fact that resistance training (RT) is a potent stimulus for muscle hypertrophy and strength gain, but it is less understood whether RT can increase maximal aerobic capacity (VO2max). The purpose of this brief review is to discuss whether or not RT enhances VO2max in young (20–40 years) and older subjects (>60 years). Only 3 of 17 studies involving young subjects have indicated significant increases in VO2max following RT, while six of nine studies in older subjects have reported significant improvements in VO2max following RT. There was a significant negative correlation between the initial VO2max and RT-induced change in VO2max. This result suggests that RT-induced increase in VO2max is dependent upon the subject’s initial VO2max. The RT-induced increase in VO2max may be elicited when their initial relative VO2max is lower than 25 ml/kg/min for older subjects and lower than 40 ml/kg/min for young subjects. Thus, RT can be expected to improve concurrently both muscular and cardiovascular fitnesses within a single mode of RT when young and old persons have initially low fitness levels. 相似文献

We show in an environment of incomplete information that monotonicity and the Pareto property applied only when there is common knowledge of Pareto dominance imply (i) there must exist a common prior over the smallest common knowledge event, and (ii) aggregation must be ex ante and ex post utilitarian with respect to that common prior and individual von Neumann–Morgenstern utility indices. 相似文献
