Inferences on the Difference of Two Proportions: A Bayesian Approach

引用

Open Journal of Statistics 2017年第1期7卷 1-15页

作者： Thu Pham-Gia Nguyen Van Thin Phan Phuc doan Department of Mathematics and Statistics Université de Moncton New Brunswick Canada Faculty of Mathematics and Computer Science Hochiminh University of Science Ho Chi Minh Vietnam

Let π=π1-π2 be the difference of two independent proportions related to two populations. We study the test H0:π≥0 against different alternatives, in the Bayesian context. The various Bayesian approaches use standard beta distributions, and are simple to derive and compute. But the more general test H0:π≥η, with η>0, requires more advanced mathematical tools to carry out the computations. These tools, which include the density of the difference of two general beta variables, are presented in the article, with numerical examples for illustrations to facilitate comprehension of results.

Dry Weight Accumulation, Root Plasticity, and Stomatal Conductance in Rice (<i>Oryza sativa</i>L.) Varieties under Drought Stress and Re-Watering Conditions

引用

American Journal of Plant Sciences 2017年第12期8卷 3189-3206页

作者： doan Cong Dien Takeo Yamakawa Toshihiro Mochizuki Aung Zaw Htwe Laboratory of Plant Nutrition Graduate School of Bioresource and Bioenvironmental Sciences School of Agriculture Kyushu University Fukuoka Japan Laboratory of Plant Nutrition Division of Molecular Biosciences Department of Biosciences & Biotechnology Faculty of Agriculture Kyushu University Fukuoka Japan Agricultural Ecology Laboratory Division of Agronomy and Environmental Sciences Department of Agro-Environmental Sciences Faculty of Agriculture Kyushu University Fukuoka Japan

Drought is one of the main factors limiting rice (Oryza sativa L.) productivity and has become an increasingly severe problem in many regions worldwide. Establishing breeding programs to develop new drought-tolerant varieties requires an understanding of the effect of drought on rice plants and the mechanisms of drought tolerance in rice. We conducted a pot experiment to explore growth characteristics, root plasticity, and stomatal conductance in six rice varieties (DA8, Malagkit Pirurutong, Thierno Bande, Pate Blanc MN1, Kinandang Patong, and Moroberekan) in response to different drought stress and re-watering conditions. Drought stress significantly depressed plant growth, root size, and stomatal conductance in all experimental varieties. These negative effects depended on both the variety and the severity of the drought stress treatment. Under moderate drought stress (10 days after drought treatment), growth was less influenced in roots than in shoots. In contrast, there was an opposite trend under severe drought stress (15 days after drought treatment), with growth being more severely affected in roots than in shoots. Rice plants recovered from drought stress in terms of dry matter accumulation, root size, and stomatal conductance after re-watering;however, the recovery pattern differed among varieties. DA8 exhibited the highest dry weight accumulation and root size (root length, root surface area, root volume, fine root length, and thick root length) under well-watered, drought stress, and re-watering conditions. Kinandang Patong showed the highest recovery ability in dry matter accumulation, root length, root surface area, and stomatal conductance after re-watering. Malagkit Pirurutong expressed the poorest recovery ability in dry matter accumulation after re-watering. These three varieties might be selected for further experiments focusing on the mechanisms of drought tolerance and recovery ability in rice.

“孝”作为东方固有的家庭及社会伦理道德准则,也是中华民族传统文化的重要组成部分。它是中国伦理、人文精神最典型的表达,崇尚孝道是中国文化的鲜明特色之一。在传统伦理道德体系中,“孝”居于核心地位,它既为百善之先,诸德之本,又是百行之始,孝化之源。“孝”通过礼乐教化根植于民族心理之中,对中国古代社会产生了广泛而深远的影响。越南作为中国的近邻,自古以来中越两国关系就很密切,文化交流也十分频繁。汉代时期儒家思想就传入越南,孔子思想遂成为越南传统文化思想的主要源泉,也成为越南民族传统文化的重要的组成部分,对越南历史的发展进程产生了巨大的影响。因此,孔子孝道思想逐渐发展为越南民族核心价值。如今,每一个越南人都是以家庭为单位的,然后再进入到社会当中,就必须要恰当地运用人与人之间的关系。也就是说,离开了孝道思想,我们就会失去方向,失去自我,也就无从谈及与人相处的问题了。当代越南社会,仍然继承这一传统,以孔子孝道文化为主体,人民普遍信奉孝道,尊老爱幼,长幼有序,社会使得安定。因此,本文将就从孔子孝道的思想进行分析入手,首先探讨孔子孝道的起源及其基本内涵,其次谈到此思想传入越南的过程中,有怎样的表现及影响。另外,进一步分析关于越南当代社会的缺失的情况,孔子思想有什么积极作用,如何对社会孝道教育提出一些参考和借鉴,这是本文主要探讨的内容。本文研究孔子孝道思想对越南社会影响的原因,主要目的是发挥孔子孝道思想的积极作用,同时摒弃孔子孝道思想的消极因素。这对当代越南社会、经济、文化的发展一定会有巨大的帮助。目前,越南社会出现的虐待、遗弃父母等伦理扭曲现象,正是缺乏孝道教育的表现。本文从家庭、学校、法制等方面建设,就如何避免这些问题的发生,把传统孝道的优秀部分发扬光大,并提出以下意见建议：第一是注重家庭孝道建设;第二是加强学校孝道教育;第三是增强国家孝道法制。

Harmful Algal Blooms (HABs) in the southeastem Vietnamese coastal waters have caused large economic losses in aquacultured and wild fisheries in recent years;however, there have been few oceanographic studies on these HAB events. The present study reported an extensive HAB off southeastern Vietnamese waters during late June to July 2002 with in situ observations and analyzed the oceanographic conditions using satellite remote sensing data. The HAB had high Chlorophyll-a (Chl-a) concentrations (up to 4.5 mg m-3), occurring about 200 km off the coast and about 200 km north-east of the Mekong River mouth, for a period of about 6 weeks. The bloom was dominated by the harmful algae haptophyte Phaeocystis cf. globosa, and caused a very significant mortality of aquacultured fishes and other marine life. In the same period, Sea Surface Temperature (SST) imagery showed a coldwater plume extending from the coast to the open sea, and QuikScat data showed strong southwesterly winds blowing parallel with the coastline. The study indicated the HAB was induced and supported by offshore upwelling that bring nutrients from the deep ocean to the surface and from coastal water to the offshore, and the upwelling was driven by strong wind through Ekman transport when winds were parallel with the coastline. This study demonstrated the possibility of utilizing a combination of satellite data of Chl-a, SST and wind velocity together with coastal bathymetric information and in situ observation to give a better understanding of the biological oceanography of HABs.

Gait training at skilled nursing facilities after total joint arthroplasty

引用

中华物理医学与康复杂志 2016年第8期38卷 640-640页

作者： Haghverdian B Wright D doan LT

BACKGROUND AND OBJECTIVE With an aging population, the demand for joint arthroplasties has resulted in a surge in the number of joint replacements performed annually. Numerous studies have suggested the need for early, rapid and continuous mobilization with weight bearing after surgery to ensure an optimal outcome. This study examined the ambulatory proficiency of patients discharged to a skilled nursing facility (SNF).METHODS This retrospective study included patients undergoing total joint arthroplasty between November of 2012 and July of 2014. Records were reviewed of those discharged to a SNF, with extracted data including daily visual analog scale pain scores, distances ambulated, weight bearing status at discharge and total length of hospital *** Data concerning 68 patients from 31 sites were included in the final analysis. The average length of acute hospitalization for these patients was 2.9 days and that for SNF stay was 17.5 days. Of the patients studied, 29.4% began gait training on the day of acute hospital discharge, with 63.2% beginning on day one and 7.4% on day two. During the first four days of SNF admission, 35% of the patients had a single physical therapy session, 23.5% had two sessions, 38.2% had three sessions and 2.9% had four sessions. Those who walked on the day of admission (day zero) or the day after admission (day one) experienced a significant decline in distance ambulated (73% and 50% respectively) compared to the last acute hospital physical therapy session (P<0.001 for both comparisons).CONCLUSION This study of patients with total joint arthroplasties discharged to skilled nursing facilities found a significant decline in ambulation distance on the day of admission and the day after, relative to the last day of acute hospitalization.
