Educational intervention on dog sterilization and retention in Taiwan

We conducted a controlled randomized study to evaluate whether an educational intervention could alter dog owners’ decisions to have their dogs sterilized and to retain the dogs in the household.

One hundred and twenty-six new dog owners were recruited from 15 animal clinics across Taiwan and were successfully followed up for 3–8 months. Among them, 66 were randomly assigned to the intervention group and the other 60 were in the control group. At the end of the study, 22 had their dogs sterilized and 23 reported having an unsuccessful dog ownership. The educational intervention did not affect the owners’ decisions to sterilize their dogs (hazard rate ratio (HRR) for the intervention group against control group = 0.7, 95% confidence interval (CI) = 0.4, 1.3). We found a heterogeneous effect of the applied education on the rate of unsuccessful dog ownership. The intervention group had a higher rate of unsuccessful ownership than the control group in the first 4 months of their ownership (HRR = 19.2, 95% CI = 4.6, 79.7), and the effect reversed after 4 months (HRR = 0.5, 95% CI = 0.2, 1.1).

Land ownership and landscape structure: a spatial analysis of sixty-six Oregon (USA) Coast Range watersheds

Patterns of land ownership and forest cover are related in complex and ecologically significant ways. Using a Geographic Information System and regression analysis, we tested for spatial relationships between the structure of land ownership and forest cover across 66 watersheds in the state of Oregon (USA), Coast Range mountains. We found that in these watersheds (1) forest cover diversity increased with land ownership diversity, (2) size of forest patches increased with size of land ownership patches, and (3) connectivity of forest cover increased with connectivity of land ownership. Land ownership structure explained between 29% and 40% of the variability of forest cover structure across these watersheds. Driving this relationship are unique associations among particular ownership classes and various forest cover classes. The USDA Forest Service and the USDI Bureau of Land Management were associated with mature forest cover; private industry was associated with young forest cover; nonindustrial private forest owners were associated with a wide diversity of cover classes. Watersheds with mixed ownership appear to provide greater forest cover diversity, whereas watersheds with concentrated ownership provide less diverse but more connected forest cover. Results suggest that land ownership patterns are strongly correlated with forest cover patterns. Therefore, understanding landscape structure requires consideration of land ownership institutions, dynamics, and patterns.This revised version was published online in May 2005 with corrections to the Cover Date.     

Factors affecting changes in a landscape structure dominated by both primary and coppice forests in theFagus crenata forest region of central Japan

In order to clarify the effects of both the social and natural environment on the changes in landscape structure we analyzed landscape elements using aerial photographs taken in different years in the primary and coppice forests in theFagus crenata forest region of central Japan. The present landscape diversity calculated by Shannon's diversity index (H′) appeared to be higher than that observed in photographs from the earlier year. The site with no residential areas and dominated by primary forests had a lower level of landscape diversity than the site which included some residential areas and coppice forests. These results show that the intensity of human activities contributes to changes in landscape diversity. The landscape diversity on private land was higher than that in the national forest, and the changes in landscape structure in the national forest were different from those seen on private land. This suggests that land ownership significantly affects the changes in landscape structure. Topographic factors also affect the changes in landscape structure. Consequently, not only the natural environment (topography), but also the social environment (intensity of human activity and land ownership) strongly influence the changes in landscape structure.

The influence of dog ownership in childhood on the sociality of elderly Japanese men

In Japan, care for the elderly has been a serious social issue. The relationship between dog ownership and health of the elderly has attracted considerable attention, but it is still unclear whether dog ownership affects the health of owners. In this study, we focused on the experiences of dog ownership in the past. The questionnaire survey was conducted targeting elderly Japanese men and asking them to clarify whether the experience of dog ownership in the past influences their current mental and physical health. To examine the characteristics of the experience of dog ownership, we divided past dog owners by a hierarchical cluster analysis using the variables related to the experiences of dog ownership. We added the ‘never owned a dog’ group to the three groups that were provided by the cluster analysis, and conducted analysis of variance and multiple linear regression analysis using the variables of physical and mental health. The results showed that the group that owned their first dog at an early age and owned more dogs later scored higher in the companionship and social support scales. These results suggested that the experiences of dog ownership in childhood were related to the sociality of older men, such as the enhancement of their companionship with others.     

机构持股对房地产股票收益波动的影响研究——基于面板数据的门限分位回归模型

针对在不同的股市行情中机构持股与房地产公司股票收益波动之间的相关性问题,建立面板数据的门限分位回归模型进行检验。证实在不同的市场行情中,对于股票收益波动处于不同水平的房地产公司,机构持股的影响程度存在差异。当股市大盘出现极端情形,机构投资者加剧股市波动。大盘大跌,机构持股的促进作用随着股票收益波动的分位点的增大而增强。在盘整市,机构持股比例没有对股票收益波动产生显著影响,但其变动抑制股票收益波动。
