Recent genome studies indicate that tree shrew is in the order or a closest sister of primates,and thus may be one of the best animals to model human diseases.In this paper,we report on a social defeat model of depression in tree shrew(Tupaia belangeri chinensis).Two male tree shrews were housed in a pair-cage consisting of two independent cages separated by a wire mesh partition with a door connecting the two cages.After one week adaptation,the connecting door was opened and a brief fighting occurs between the two male tree shrews and this social conflict session consisted of 1 h direct conflict(fighting) and 23 h indirect influence(e.g.smell,visual cues) per day for 21 days.The defeated tree shrew was considered the subordinate.Compared with na?ve animals,subordinate tree shrews at the final week of social conflict session showed alterations in body weight,locomotion,avoidance behavior and urinary cortisol levels.Remarkably,these alterations persisted for over two weeks.We also report on a novel captive conditioning model of learning and memory in tree shrew.An automatic trapping cage was placed in a small closed room with a freely-moving tree shrew.For the first four trials,the tree shrew was not trapped when it entered the cage and ate the bait apple,but it was trapped and kept in the cage for 1 h on the fifth trial.Latency was defined as the time between release of the tree shrew and when it entered the captive cage.Latencies during the five trials indicated adaptation.A test trial 24 h later was used to measure whether the one-trial trapping during the fifth trial could form captive memory.Tree shrews showed much longer trapping latencies in the test trial than the adaptation trials.The N-methyl-d-aspartate(NMDA) receptor antagonist MK-801(0.2 mg/kg,i.p.),known to prevent the formation of memory,did not affect latencies in the adaptation trails,but did block captive memory as it led to much shorter trapping latencies compared to saline treatment in the test trial.These results demonstrate a chronic social defeat model of depression and a novel one-trial captive conditioning model for learning and memory in tree shrews,which are important for mechanism studies of depression,learning,memory,and preclinical evaluation for new antidepressants. 展开更多

Diversity in the biophysical and socio-economic attributes of agricultural systems makes them uniquely niche based. Farmers are expert in local biophysical and socio-economic situations and can contribute in developing pragmatic indicators of agro-environmental development. During evaluation of an agricultural research project in Yunnan, China, local farmers were capable of evaluating the effects of modified technologies on existing cropping systems and discussed their attitudes to the interventions using their own indicators. Farmers' response can be grouped into seven major aspects: i) effects on income, ii) effects on production resources, iii) effects on crop management, iv) existing local knowledge about the technology, v) availability of inputs, vi) access to information, and vii) socio-economic conditions of farming households. Farmers concluded that environmental conditions in the experimental catchment in comparison to an adjacent untreated catchment were better in terms of soil and water losses, vegetation cover and natural resources, infrastructures and catchment management, use of environmentally-friendly technologies, and crop productivity. Success in soil and water conservation programmes depends on the efforts of the farmers and other local users and their greater involvement helps to identify more pragmatic indicators. Furthermore, it increases ownership of the programme, enhances interactions with the project scientists, increases farmers' awareness of ago-environmental problems and their possible consequences. These development will enable scientists to develop better targeted interventions and increase the likelihood of adoption of tested technologies by local communities. The use of paired adjacent catchments improved evaluation activities and is proposed as good practice for future catchment improvement programmes. 展开更多

Epibacterial community structures on marine macroalgae are host-specific but temporally and spatially variable. In this study, we investigated the structure of epibacterial communities on the surfaces of four red macroalgae, Gracilaria lemaneiformis, Gloiopeltisfurcata, Mazzaella sp. and Porphyra yezoensis, by analyzing the sequences of 16S rRNA gene libraries. Healthy individuals of all macroalgae species were collected in winter from a farm at Dalian, China. The results showed that the epibacterial communities were mainly dominated by ct-Proteobacteria, 7-Proteobacteria and Bacteroidetes. Deinococcus-Thermus, Spirochaetes and e-Proteobacteria were also found. The majority of cloned sequences shared the greatest similarity to those of culturable organisms. A large portion of sequences from the ct-Proteobacteria homed in Roseobacter clade, i.e., genera Ahrensia, Roseovarius, Litoreibacter, Octadecabacter, Thaiassobacter and Sulfitobacter, while members of Bacteroidetes mainly belonged to family Flavobacteriaceae. The cloned sequences could be separated into 66 OTUs at 0.01 distance value, and rare common OTUs were found among libraries. At genus level, Pseudoa#eromonas dominated Gr. lemaneiformis and GI. furcata libraries, accounting for 72.2% and 47.3%, respectively. Sulfitobacter dominated P. yezoensis library, accounting for 35.4%. A previously undefined cluster within Deinococcus-Thermus dominated Mazzaella sp. library, accounting for 24.6% of the all. These results indicated that a broad range of bacteria inhabited the surfaces of these macroalgae. 展开更多

Around two thirds of the Swedish rural areas experienced positive net migration during the period 2003-2005. This paper examines the development in the Swedish rural areas from the perspective of the "new rurality" or the new rural economic order with regard to migratory movements. The paper analyzes determinants of net migration to rural areas in general and to different types of regions, and the impacts of in-migration on rural labor markets, self-employment and other socio-economic conditions. The determinants of the migration pattern were mainly the size of adjacent local and regional centers, income and education levels that all had positive impacts, while commuting distance and unemployment rate had contrary effects. In comparison with the original inhabitants, the newcomers had lower incomes, a lower employment ratio and a lower degree of entrepreneurial activities, but higher education levels. These differences might be explained by the age differences between stayers (older) and in-migrants (younger). This indicates that the two groups were in different stages of their life cycles. One central conclusion drawn from the paper is that the effect of in-migration on the composition of the rural population is about the same in rural areas all over Sweden. 展开更多

It takes place in a social context and responds to specific social conditions. Many countries in Africa (especially in the sub-Saharan area) consider that the main potential contribution an agenda for socio-economic development could provide would be to put socio-anthropoiogical studies of development back at the center of concerns. Likewise, the nature of the commitment of theorists and practitioners of yesterday and today, in a context that is described as post-colonial, especially around development projects policies, is to encourage more comprehensive and effective new approaches with regard to development in Africa. Moreover, achieving development requires also global actions to deliver on the legitimate aspiration towards further economic and social progress, requiring growth and employment, and at the same time strengthening the education system by using academic institutions, and systems to the right to make decisions about programs, quality standards, and a veriety of other educational factors. 展开更多

Objective:This study aimed to identify the challenges of community health nurses(CHNs)in delivering effective community health care to achieve universal health coverage(UHC)in Myanmar.Methods:A total of 30 CHNs from township health centers in the northeastern,southern,and western parts of Myanmar were purposefully recruited for quantitative and qualitative interviews.Quantitative data were processed using Microsoft Excel software,and qualitative data were analyzed using thematic analysis.This study is registered with researchregistry6201.Results:Around the country,30 CHNs uncovered their hardships in implementing primary health care to achieve UHC.Over 90%of the participants agreed to the problem of inadequate health infrastructure,while half of them felt unmotivated when they encountered role conflicts among various cadres of healthcare providers and poor opportunities for career promotion.Major problems arose from the lack of standard professional education at the entry point to community settings because most CHNs did not achieve specialized training in providing public health services.Complications are incapable of evaluating health services for policy-making and the inability to conduct health research to develop evidencebased practices.Insecure work and living conditions,unsupportive community relationships,and undereducation in professional practices were supportive major themes explored by CHNs to achieve a deeper understanding of the barriers to UHC.Not only the health system itself but also the population and other geographical factors have contributed to many challenges to CHNs.Conclusion:Myanmar’s CHNs face many challenges in achieving UHC.These challenges are not confined to the health sector.Some situations,such as geographical barriers and transportation problems,remain persistent challenges for healthcare providers.This study highlights the fact that current health systems should be strengthened by qualified healthcare providers and sufficient infrastructure.Meanwhile,public empowerment plays a critical role in promoting health development. 展开更多

This paper will examine the essay, "Night Walks" (2000), to see how Charles Dickens (1812-1870), a social-realist writer of the Victorian era, has used elements adapted from the Romantics in order to draw attention to the pitiable social conditions of Victorian London. Dickens' the realist paradoxically reflected a readiness to think and feel "without immediate external excitement". He expressed his alignment with Romanticism by way of a cultivation of feeling and empathizing. His genius was, as expressed by Bagehot, "essentially irregular and unsymmetrical" because he was "utterly deficient in the faculty of reasoning". His daily, or rather nightly walks provided him with the inspiration to follow the Romantic tradition of writing on walks. The essay under consideration, "Night Walks", clearly supports the notion that Romanticism was fallaciously opposed to realism. The paper will examine the ways in which the theme, style, and structure of the essay evoke the preoccupation of a Romantic soul--for whom the walk becomes a space for "encounter and reflection"--and the Romantic mind which is empowered by "imaginative self definition or discovery". 展开更多

This paper aims to establish a methodological frame work and its validation as a response to the need of a demand management tool in the face of recurring comparisons of building revitalization or retrofits. As the investment and implementation actions improve and the social economic criteria are delimited by regulatory frameworks, it is extremely necessary to monitor previous performances and further prospects, regarding projects, it is necessary to measure the extent of which efforts have been meeting regulatory requirements and aiming to contribute with sustainable development. In this context, the use of indicators has been a major management tool. 展开更多

A great number of people have been living in insufficient cities which can not suffice either daily necessities or social and cultural necessities of human for decades in spite of a lot of majestic cities were set in the world recently. Especially many immigrant people live in close and crowded and squalid suburbs by always suffering from their social condition and worrying about their future in Turkey. Everybody worries about living in a humanitarian environment and correct social occasion and tries to reach communication facilities in his surroundings for living in a society as a human. Each immigrant looks forward to settle in an untouched side and set a life for himself there. Untouched areas and a few undamaged side are rapidly being destroyed because of migrations and while cities expand towards untouched areas, immigrant people immediately settle insufficient sides. When they live in insufficient life, whole they particularly need communication facilities as human in their defective sides. Countries steadily resemble large cities without contain social ambience and communication facilities. Historical experiences have changed social necessities and habits of people into communication facilities during history. Because people need communication the most in their life. 展开更多

The aim of this paper is to elucidate the nature and viability of teaching philosophy establishing their impact on the construction of philosophy in developing countries such as Peru. This article is inserted in the context of the need to rethink the missed philosophy marked by Badiou who proposes two ideas and binding areas: Philosophy is a reflection on all that is in the infinite universe, including humans; and, being the reflection (thinking) an innate characteristic of the human being, then, in some way, we are philosophers. It follows two thoughts that philosophy is not taught or learned but is assumed in the measure of their level of education and knowledge. In such conditions, it is not the teaching of philosophy that which has to build philosophy or form "philosophers," but is education. It is established, therefore, that between the philosophy and the education, there is a direct relationship in the sense that the first is based on the second and a good education is a prerequisite for the development of philosophy in a society condition. For this important reason, developing countries still do not have adequate conditions for sustained construction of philosophy because they have educational models that prevent it from radiating a good education to society. Being a good carrier of a good education philosophy, a poorly educated person has limitations to acquire of philosophical thinking. Therefore, these reasons are that in these countries, the teaching philosophy has proved to be unsuccessful. Being poor education in underdeveloped societies, where language skills and science are below international standards, it is easy to deduce that such societies are facing philosophy and devoid of conditions to form part of their cultures. Our hypothesis is that philosophy in a society cannot be built on the basis of the teaching of philosophy, but on the basis of a good education. The fact that in underdeveloped societies, as is the case of Peru, there is no philosophy in terms of what it means in modern times, is not because there is no teaching of philosophy but because there is archaic educational models. In these countries, the education model is anti-philosophical. Our approach is based on the education system prevalent in underdeveloped countries such as Peru, which is not feasible "teaching philosophy" to steadily build philosophy as part of national cultures, and instead it is necessary for the design and implementation of new models of education. 展开更多

The work's main purpose was to design and implement a model of agricultural production for the attention of food demand of the coal complex in the center of the department of Cesar, Colombia, by mounting Profitable Productive Units in rural areas of the zone with mining influence. The aforementioned rural communities are at a socioeconomic disadvantage concerning to the local economic development policies. It was taken a rural society with socio-economic conditions at a disadvantage, level 1 in the classification scale of 1 to 5 of Colombia, several associations were organized in each one of the affected municipalities with strong agricultural vocation to train them in profitable production strategies, authors performed technical and technological support for 12 months. In synthesis, there were meaningful differences among gross income per month of people who worked in the projects of the Young Rural Entrepreneurs, a fact confirmed by the P-value 0.00000005 (Prob. 〉 F) and the F-value 29.3, both denote the significance statistic for this case is best gross income per month of persons covered by the program, this implies that for a person of the rural community it is more meaningful economically linked to the SENA's Young Rural Entrepreneurs, in contrast to search for jobs in the informal sector, there is even an average value of 530.000 COP/month (about 265 US/month) higher than the statutory minimum wage for 2009, equivalent to 497.000 COP/month (about 245 US/month). 展开更多

Generally, the sequence decision of the development and utilization of Chinese mineral resources is based on national and provincial overall plan of the mineral resources. Such plan usually cannot reflect the relative size of the suitability of the development and utilization of mineral resources. To solve the problem, the paper has selected the gift condition, the market condition, the technological condition,socio-economic condition and environmental condition as the starting-points to analyze the influential factors of the priority-sequence of mineral resources' development and utilization. The above 5 conditions are further specified into 9 evaluative indicators to establish an evaluation indicator system. At last,we propose a decision model of the priority sequence based on grey relational analysis method, and figure out the observation objects by the suitability index of development. Finally, the mineral resources of a certain province in China were analyzed as an example. The calculation results indicate that silver(2.0057), coal(1.9955), zinc(1.9442), cement limestone(1.9077), solvent limestone(1.5624) and other minerals in the province are suitable for development and utilization. 展开更多

Development and judicious management of available water resources play a key role for economic upliftment of any region. The agricultural pattern and social and demographic status in the upper basin of the Dulung Nala Stream (a tributary of the Subarnarekha River) in the western part of the State of West Bengal, India, reveals growing demand of water in the basin. The paper reports different management plans involving different types of water harvesting structures (and associated different types of water distribution systems) and different crop combinations and with benefit/cost ratios varying from 1.3 to 11.2 for the basin. The study points out that the judicious choice of both the water harvesting structure as well as the water distribution system is important. Proper planning of crop pattern is also to be emphasized for reaping maximum benefit. It further emphasizes that cost- benefit ratio cannot solely govern the choice of structure and that maximum utilization of catchmental water and thus enhancement of agricultural output (and also economic return from the catchment) i.e. quantum of benefit is also important. The water harvesting structures proposed in this study can be implemented in other semi-arid regions of India having almost the same climatic and socio-economic conditions. 展开更多
