AbstractBuilding capacity in ocean affairs, the law of the sea, and marine scientific research in relation to the needs of developing countries is an integral part of the U. Convention on the Law of the Sea and associated instruments, including the International Maritime Organization (IMO) treaty regime. This article traces the development of capacity-building initiatives at the World Maritime University (WMU) over the past three decades, including the establishment of the WMU–Sasakawa Global Ocean Institute in 2018. The establishment of the new institute should be viewed within the wider context of the extraordinary philanthropy of the Sasakawa Peace Foundation and the Nippon Foundation in building human resource capacity and in supporting advanced academic research on complicated and contentious ocean issues. The article describes the extensive consultation process that informs the research, education, and capacity development agenda of the new institute, including work on the ocean-related goals of the 2030 Agenda for Sustainable Development. 相似文献

The parts-based engineering approach in synthetic biology aims to create pre-characterised biological parts that can be used for the rational design of novel functional systems. Given the context-sensitivity of biological entities, a key question synthetic biologists have to address is what properties these parts should have so that they give a predictable output even when they are used in different contexts. In the first part of this paper I will analyse some of the answers that synthetic biologists have given to this question and claim that the focus of these answers on parts and their properties does not allow us to tackle the problem of context-sensitivity. In the second part of the paper, I will argue that we might have to abandon the notions of parts and their properties in order to understand how independence in biology could be achieved. Using Robert Cummins’ account of functional analysis, I will then develop the notion of a capacity and its condition space and show how these notions can help to tackle the problem of context-sensitivity in biology. 相似文献

A mathematical function describing the various kinds of survivorship curve is formulated with the useful parameter, environmental capacity. Three types of the survivorship curve illlustrated byDeevey can be obtained from changing the value of this function. When a cohort is large and the competition occurs in the scramble type, this function shows the third type ofDeevy 's and this to the first type in the case of low density and the contest type of competition. But the second type would rather be obtained by the action of density independent agencies. 相似文献

Among philosophers of science, there is now a widespread agreement that the DN model of explanation is poorly equipped to account for explanations in biology. Rather than identifying laws, so the consensus goes, researchers explain biological capacities by constructing a model of the underlying mechanism.We think that the dichotomy between DN explanations and mechanistic explanations is misleading. In this article, we argue that there are cases in which biological capacities are explained without constructing a model of the underlying mechanism. Although these explanations do not conform to Hempel’s DN model (they do not deduce the explanandum from laws of nature), they do invoke more or less stable generalisations. Because they invoke generalisations and have the form of an argument, we call them inferential explanations. We support this claim by considering two examples of explanations of biological capacities: pigeon navigation and photoperiodism. Next, we will argue that these non-mechanistic explanations are crucial to biology in three ways: (i) sometimes, they are the only thing we have (there is no alternative available), (ii) they are heuristically useful, and (iii) they provide genuine understanding and so are interesting in their own right.In the last sections we discuss the relation between types of explanations and types of experiments and situate our views within some relevant debates on explanatory power and explanatory virtues. 相似文献

The purpose of this double clinical study was (1) to evaluate the effect of one single intake (300 ml) of red wine (RW) on the plasma antioxidant capacity (pAOC) and plasma phenolics over the 24-h time period following the intake, and (2) to compare the long-term effects of daily intakes (250 ml/d) of RW, white wine (WW) and Champagne (CH) on the plasma and LDL characteristics of healthy sujects. In the first part, blood samples were collected just before and after wine consumption. In the second part, subjects received the 3 types of wine successively, only at the mealtime, over 3-week periods separated by a 3-week wash out. Blood samples were drawn in fasting condition before and after each 3-week wine consumption period. The peak of pAOC was at 3-4 h following the single intake of RW, that of catechin was at 4 h (0.13 μmol/l) and that of gallic acid and caffeic acid was earlier (≤?1.5 and 0.3 μmol/l, respectively). In plasma, the major form of gallic acid was 4-O-methylated, but a minor form (the 3-O-methyl derivative) appeared. In the long term study, no wine was able to change LDL oxidizability, but some other parameters were modified specifically: RW decreased pAOC (without changing TBARS and uric acid plasma levels), LDL lipids and total cholesterol (TC), and increased plasma apoA1, whereas CH increased plasma vitamin A. The beneficial effect of RW seems to mainly be explained by its action on lipid and lipoprotein constants, and not by its antioxidant one. 相似文献

The capacity needs of online services are mainly determined by the volume of user loads. For large-scale distributed systems
running such services, it is quite difficult to match the capacities of various system components. In this paper, a novel
and systematic approach is proposed to profile services for resource optimization and capacity planning. We collect resource
consumption related measurements from various components across distributed systems and further search for constant relationships
between these measurements. If such relationships always hold under various workloads along time, we consider them as invariants
of the underlying system. After extracting many invariants from the system, given any volume of user loads, we can follow
these invariant relationships sequentially to estimate the capacity needs of individual components. By comparing the current
resource configurations against the estimated capacity needs, we can discover the weakest points that may deteriorate system
performance. Operators can consult such analytical results to optimize resource assignments and remove potential performance
bottlenecks. In this paper, we propose several algorithms to support capacity analysis and guide operator’s capacity planning
tasks. Our algorithms are evaluated with real systems and experimental results are also included to demonstrate the effectiveness
of our approach.

Objectives:Children with Duchene muscular dystrophy have weak muscles, which may impair postural adjustments. These postural adjustments are required for gait and dynamic balance during the daily living activities. The aim was to compare between the effect of bicycle ergometer versus treadmill on functional walking capacity and balance in children with Duchenne muscular dystrophy.Methods:Thirty boys aged from 6 to 10 years old diagnosed as Duchene muscular dystrophy participated in this study. Children were assigned randomly into two groups (A&B). Children in group (A) underwent a designed program of physical therapy plus aerobic exercise training in form of bicycle ergometer while, group (B) received the same program as group (A) and aerobic exercise training by treadmill for one hour, at three times a week for three successive months. Functional walking capacity and balance were assessed before and after treatment by using the 6-minute walk test and Biodex balance system equipment respectively.Results:The post treatment results revealed significant difference in all measured variables (P<0.05) as compared with its pre-treatment results. Post-treatment values indicated that there was a significant difference in all measured variables in favor of group B.Conclusions:treadmill training as an aerobic exercise can improve walking capacity and balance more effectively than bicycle ergometer in children with Duchenne muscular dystrophy. 相似文献

China′s rich floral diversity includes more than 33000 vascular plant species, representing approximately 10 percent of all known plant species. Over half of these species are endemic to China. However, China′s rapid economic development in the last 30 years and continuous population growth have seriously damaged plant resources in the wild and the ecological environment, resulting in a dramatic increase in the number of endangered species. There are nearly 4000 to 5000 higher plants that are now threatened or on the verge of extinction. To help halt the loss of Chinese plant diversity, Botanic Gardens Conservation International (BGCI) has developed a China programme and opened its first office based in Guangzhou in 2008. This office works along with Chinese partners aiming to secure Chinese plant diversity through integrated conservation approaches with reintroduction/population reinforcement, engagement of local communities in conservation activities, capacity building in horticulture and environmental education and public outreach. 相似文献
