Although the world has reached a highly urbanized stage, there is still a large rural population and a large rural area, and various rural problems to be solved. Many developing and underdeveloped countries have garnered little attention in rural studies and have even more complicated rural development problems.To clarify the intellectual contribution of rural studies and to integrate research into practice, in this study,we conducted a bibliometric analysis of the last 10 years of rural studies from a geographical perspective by comparing and integrating other related studies. CiteSpace was used to analyze the leading journals, keyword frequency and evolution, research hotspots, and research trends of 3530 articles. Our findings include four sections presented as main contents in details. In the end, we propose at least 10 elements to the rural geography framework based on the viewpoints of predecessors and future requirements. 展开更多

This case study presents different strategies that were explored by the patient’s mother (who is a researcher in music and medicine) when her 17-year-old daughter was diagnosed with ME (Myalgic Encephalomyelitis), also known as Chronic Fatigue Syndrome (CFS). ME is not widely recognized in the Global as well as the Swedish population at large, and within healthcare, there are no standardized recommended treatments, partly due to the lack of published evidence-based studies. This case study aims to provide insights into how the Swedish healthcare system works, how different clinics and hospitals within it operate and interconnect;and how these contribute to health outcomes after 15 months of treatment. 展开更多

Objective:The aim of this study was to explore the burden of care for patients undergoing hemodialysis from the experiences of family caregivers.Methods:In this qualitative study,a content analysis approach was used for data collection and analysis.Participants were 16 family caregivers selected through purposive sampling from four medical education centers affiliated with Ahvaz Jundishapur University of Medical Sciences,Iran.Semi-structured interviews were held to collect data.Results:Four categories were developed as follows:‘care challenges’,‘psychological vulnerabilities’,‘the chronic nature of care’and“care in the shade”.The categories led to the development of the main theme of‘progressive exhaustion’experienced by the family caregivers during the provision of care to patients undergoing hemodialysis.Conclusion:Family caregivers have a significant role in the process of patient care,and this role leads them to progressive exhaustion;therefore,the overall health of the caregivers should be taken into account and more attention should be paid to their quality of life,social welfare,and satisfaction level. 展开更多

This paper reports the application of pulse discharges along with catalysts in treat- ing the exhaust gas at higher temperatures. In the present work a plasma reactor, filled with catalysts, called as plasma catalytic reactor, is studied for removal of oxides of nitrogen, total hydrocarbons and carbon monoxide. The experiments are conducted on an actual diesel engine exhaust at no-load and at different temperatures starting from room temperature to 300°C. The removal efficiencies of these pollutants are studied. The experiments are carried out with both con- ventional and non-conventional catalysts. The idea is to explore the pollutant removal efficiency characteristics by non-conventional catalysts. The efficiency results are compared with that of conventional catalysts. The experiments are carried out at a constant pulse repetition rate of 120 pps. Both pellet and honeycomb type catalysts are used in the study. 展开更多

To prevent the environment from polluting, the request of emissions control legislation becomes more stringent. New legislation prescribes not only the emissions limitation of vehicles, but also testing instruments and methods. Test car must be operated on the chassis dynamometer and data must be collect ed and analyzed with prescriptive exhaust analysis system as well. The mass of harmful exhaust gas, containing the concentration and volume of emis sion, which is independent from the model of automobile and engine, can be used as a criterion to evaluate the pollution of an automobile. Constant Volume Sampl e System (CVS) is used to measure vehicle emissions, but it is too expensive to apply extensively. The Vehicle Mass Analysis System(Vmas), a new vehicle exhaust mass analysis system produced in USA late 1990s,is used to test and analyze veh icle exhaust. As a test instrument, it has the virtue of cheapness and easy mana geability. In this paper, Vmas is used to measure the emissions of a light truck CA1020F. A ccording to 15 running modes of Vehicle Exhaust Legislation, the test car is ope rated on the chassis dynamometer and data are collected and analyzed with Vmas. The test results show that it is viable to measure and evaluate automobile emiss ion with Vmas. Most of HC exhaust is produced when the car is decelerating. The major factor that influences the mass of HC emission is the sudden decrease of e ngine load causing incomplete combustion in decelerating mode. Test results indi cate CO and NOx are mainly produced in the process of increasing load. The forme r reason is incomplete combustion and the latter is high burning temperature cau sed by the increasing load. The methods of reducing automobile emission are also discussed in this paper. 展开更多

Due to the complexity of leadership and its variability across situations,it is suggested that research on leadership should focus on attempts to understand leadership in specific situations or roles,and develop local knowledge about leadership in each situation or role.This paper validates the possibility and importance of building indigenous leadership theories from historical perspective.We demonstrated how to carry out research on indigenous Chinese leadership from a historical perspective by comparative case studies using historical data.Based on the principles of typicalness,representativeness,and comparativeness,we selected six counterparts of political elites in ancient China as comparative cases,which includes Guan Zhong&Shang Yang(organizational reformer),Liu Bang&Xiang Yu(entrepreneur),Li Shimin&Qin Shihuang(intergenerational transition successor),Zhuge Liang&Zeng Guofan(professional manager),Lu Su&Zhang Juzheng(mess-to-order maker),and Zuo Zongtang&Wang Anshi(national dream driver).The paper aims to develop indigenous leadership theory specific to Chinese mental states and culture. 展开更多

The studies of British Marxism can be divided into two periods: the upsurge period (1980s-1990s) and thedeepening development period (the beginning of 21st century to now). The studies mainly feature expansions ofresearch scopes, disputes in its definition and boundaries, and transformations from case studies to comprehensiveresearch. There are reasons to expect its future prosperity, if research work can fulfill the following three tasks:strengthening basic studies with literature collections and material analyses, changing logical perspectives byadhering to a holistically structured system, and with an orientation to the practical issues in China, conductingBritish Marxism studies under the context of the socialism with Chinese characteristics. 展开更多
