Ideological work is an extremely important work,which concerns the cohesion of the Communist Party of China,the centripetal force of the cause of socialism with Chinese characteristics,the long-term stability of the country and the development and stability of society.Since the 18th National Congress,series of important discussions have been proposed by General Secretary Xi Jinping around ideological work,and the domestic theoretical circle has launched a systematic,comprehensive and in-depth study of ideological identity from different subject areas and levels,and has achieved a series of important results.This paper takes the mainstream ideological identity of college students as the starting point,and combines the questionnaire to analyze the current status of mainstream ideological identity of college students from two dimensions:theory and practice.First,it summarizes and analyzes the current status of mainstream ideological identity of college students through the questionnaire,and explores its existing problems and influencing factors.The second is to find out the reasons for the pluralistic ideology of some college students from different research perspectives.Third,in terms of cultivating college students’ideological identity,more targeted realization paths are proposed from three dimensions:innovating ideological and political education in colleges and universities,strengthening public opinion publicity,and building practical education platforms,so as to improve the accuracy of mainstream ideology and explore the path of college students’mainstream ideological identity. 展开更多

The hydrological processes of mountainous watersheds in inland river basins are complicated.It is absolutely significant to quantify mountainous runoff for social,economic and ecological purposes.This paper takes the mountainous watershed of the Heihe Mainstream River as a study area to simulate the hydrological processes of mountainous watersheds in inland river basins by using the soil and water assessment tool(SWAT)model.SWAT simulation results show that both the Nash–Sutcliffe efficiency and the determination coefficient values of the calibration period(January 1995 to December 2002)and validation period(January 2002 to December 2009)are higher than 0.90,and the percent bias is controlled within±5%,indicating that the simulation results are satisfactory.According to the SWAT performance,we discussed the yearly and monthly variation trends of the mountainous runoff and the runoff components.The results show that from 1996 to 2009,an indistinctive rising trend was observed for the yearly mountainous runoff,which is mainly recharged by lateral flow,and followed by shallow groundwater runoff and surface runoff.The monthly variation demonstrates that the mountainous runoff decreases slightly from May to July,contrary to other months.The mountainous runoff is mainly recharged by shallow groundwater runoff in January,February,and from October to December,by surface runoff in March and April,and by lateral flow from May to September. 展开更多

To understand the retention mechanism of phenol in mainstream cigarette smoke by cellulose acetate(CA)filters,the phenol filtration efficiency,the phenol distribution in the gas phase and particulate phase during filtration and the retention characteristics of the filter for both the gas phase and particulate phenol species were investigated.The distribution of particulate bound phenol as a function of the particle size was examined.The ratio of phenol transferring from the particulate phase to the gas phase during smoke flowing through the CA filter were studied.Retention mechanisms for phenol in the gas phase as well as particulate phase phenol in the filter and the phase transition of phenol were proposed.Phenol filtration efficiency of the cigarette filter was calculated based on the proposed retention mechanisms and compared with available experimental data.The results showed that:1)Comparing with nicotine and the other particulate bound smoke constituents,CA filter exhibited a certain retention selectivity for phenol.2)Although phenol was mainly bound to the particulate phase of the cigarette mainstream smoke,about 35% of gas phase phenol was found at the tobacco end of the filter,whilst this dropped to approximately 0 at the mouth end of the filter,mostly by selective chemical adsorption.3)The weighted average smoke particle size and particulate phenol was 0.44 and 0.38 pm,respectively.The filtration efficiency of the filter to particulate phenol was near 40%.4)About 19% of particulate bound phenol transferred to gas phase when smoke passing the filter,and was selectively adsorbed.5)The overall filtration efficiency of the CA filter for phenol in mainstream cigarette smoke was 68.7%,with-7.7% variation compared with experimental data.The results demonstrated the phase transition of phenol during the filtration process and the selective retention with varying particle sizes.Our results showed that the application of CA filter in product designs reduces harmful constituents such as phenolic compounds in mainstream cigarette smoke. 展开更多

[Objective] The study aims at evaluating the water environmental quality of the Liaohe River mainstream. [ Method] The water quality of two monitored sections in the mainstream of the Liaohe River from 2004 to 2010 was assessed by the fuzzy comprehensive appraisal combined with weighted average, and some practicable measures were put forward according to the assessment results. [ Result] From 2004 to 2010, the water quality of the Liaohe River mainstream varied from Grade II to III at Zhuershan section, and changed from Grade II to IV at Xing'an section, becom- ing better on the whole. In addition, the major factor influencing the water quality is the small content of dissolved oxygen (DO) in the water body. Meanwhile, the pollution of the water body mainly results from the discharge of organic matter consuming oxygen largely, and ammonia nitrogen should be paid more attention to. [ Conclusion] The research could provide scientific references for the protection of water environment and its pollu- tion control in the mainstream of the Liaohe River. 展开更多

Most of these settlements are built in areas that are susceptible to extreme weather conditions such as flooding. Such conditions have significantly contributed to the destruction of housing stock and other valuable properties. There is considerable awareness amongst people living in the informal settlements, government representatives and other key stakeholders about the various flood risks affecting informal settlements. Based on this understanding, several attempts to minimize flood risks have been initiated in Dar es Salaam, Tanzania, yet these initiatives have largely failed to deliver the desired impacts. This article aims to investigate core reasons for this through a case study of Keko Machungwa Informal settlement in Dar es Salaam City. The study explores the extent to which mainstreaming of disaster risk reduction (DRR) in housing development in informal settlements has been considered and implemented, and recommends measures for improvement. Key methods employed for the research included physical observation, household interviews, mapping, photographing, and in-depth interviews. Overall, the study found that mainstreaming of DRR in housing development was hardly practiced at the household level, as houses were predominantly being built without resistant building materials and supervision of relevant professionals. In order to mainstream DRR in housing development in informal settlements, it is recommended that mainstreaming DRR be embedded in laws and policies, highly vulnerable parts of the settlement be declared protected wetland and that the government direct its efforts towards regulating, controlling and monitoring the housing development sector. That letter can be achieved by emphasizing the use of flood resistant building materials and establishing resilient infrastructures for flood mitigation in every flood prone informal settlement. 展开更多

The adoption and use of social media has played a major role in the changes in journalists’ work. The use of these new means has become indispensable to the daily tasks and work of journalists in most news organizations. It is no longer possible to bypass these means when it comes to searching for information and news, or in production, publishing, distribution and marketing, or even in interaction with the public. The characteristics of ease, speed, immediacy, interactivity, and being free of charge that characterize them, have made them a useful technological tool, which is influential and necessary not only for the future of the journalist’s career but also for the future of the news organization itself. With the growing number of users of social media around the world, journalists and news organizations have found additional access, more important than previous channels, to access additional sources that help them market and interact with their work in a new dynamic environment completely different from previous communication models, and put audience activity at the forefront. In this study, which is part of the Technology Acceptance Model (TAM), the author tries to understand and analyze the factors of adoption and use of social media as a new technological tool by Bahraini journalists and to identify their new role in the changes in journalism. In addition, the study attempts to examine the implications in relation to the future of the press profession and the economic model of the news organization. The results showed a clear adoption and an increased use of social media by journalists, who consider it a key element in the development of journalism, and an inevitable strategic choice for the future of the news organization. They also expressed their full awareness of the problems surrounding the issue of precision and credibility of news accessed through social media. 展开更多

Through the deep data analysis of the cosmetics industry, it can be found that the changes in population structure, differences of consumption habits, and income factors which have led to the intergenerational replacement of Chinese consumers. Middle-aged crowd in China, their consumption concept tend to be relatively conservative, while for young generations, their income level is becoming higher. The purchasing power and consumption tendency of such young consumer groups are significantly higher than that of middle-aged and elderly people. Relevant data show that the consumption intention and consumer confidence index of the new generation (born in 1995 and beyond) are significantly higher than the overall level of ditferent age groups, and the growth rate are accelerating. In the urban residents’ consumption in 2012, the contribution of the new generation is 15%, and it is expected to reach 35% by 2020, which fully shows that the new generation of consumers has begun to become the mainstream of new generation consumption. 展开更多

China has made remarkable achievements in poverty governance.It is of far-reaching significance to observe and interpret poverty reduction in China from the perspective of human rights.Mainstreaming human rights provides a two-way perspective of observation.It can help observe poverty reduction in the"kaleidoscope"of human rights,and also can help understand human rights through poverty reduction,in particular,observe the status and development trend of human rights in national governance through the"governance revolution"triggered by poverty governance.An examination of poverty governance from the perspective of human rights will reveal that poverty alleviation has become a major"human rights project".The discourse,goals and approaches to poverty reduction have been marked with human rights imprints,and they are ultimately translated into the realization of the right to be free from poverty in the two dimensions of survival and development.To examine human rights through poverty reduction will reveal that the way of poverty governance is changing,which implies a development view based on human rights,and stimulates the subjectivity of citizens in the trend of democratic participation and pluralistic governance.The above change drives and advances the mainstreaming of human rights in the field of national governance and the deep change of governance.Definitely,how these signs and trends continue to thrive in a broader field and obtain more institutional support after 2020 in the post-poverty alleviation era. 展开更多

This study investigated the removal of heavy metal ions from cigarette mainstream smoke using chitosan.Chitosan of various deacetylation degrees and molecular weights were manually added to cigarette filters in different dosages.The mainstream smoke particulate matter was collected by a Cambridge filter pad,digested by a microwave digestor,and then analyzed for contents of heavy metal ions,including As(III/V),Pb(II),Cd(II),Cr(III/VI) and Ni(II),by graphite furnace atomic absorption spectrometry(GFAAS).The results showed that chitosan had a removal effect on Pb(II),Cd(II),Cr(III/VI) and Ni(II).Of these,the percent removal of Ni(II) was elevated with an increasing dosage of chitosan.Chitosan of a high deace tylation degree exhibited good binding performance toward Cd(II),Cr(III/VI) and Ni(II),though with poor efficiency for Pb(II).Except As(III/V),all the tested metal ions showed similar tendencies in the growing contents with an increasing chitosan molecular weight.Nonetheless,the percent removal of Cr(III/VI) peaked with a chitosan molecular weight of 200 kDa,followed by a dramatic decrease with an increasing chitosan molecular weight.Generally,chitosan had different removal effects on four out of five tested metal ions,and the percent removal of Cd(II),Pb(II),Cr(III/VI) and Ni(II) was approximately 55%,45%,50%,and 16%,respectively.In a word,chitosan used in cigarette filter can remove toxic heavy metal ions in the mainstream smoke,improve cigarette safety,and reduce the harm to smokers. 展开更多

An improved method was developed for the determination of the four major tobacco-specific nitrosamines(TSNAs) in mainstream cigarette smoke. The new method offers decreased sample preparation and analysis time as compared to traditional methods. This method uses isotope dilution liquid chromatography coupled with a tandem mass spectrometer with electrospray ionization and is significantly more sensitive than traditional methods. It also shows no evidence of artifactual formation of TSNAs. Sample concentrations were determined for four TSNAs in mainstream smoke using two isotopically labeled TSNAs analogues as internal standards. Mainstream smoke was collected on an industry standard 44-mm Cambridge filter pad, extracted with 0.1 mol/L ammonium acetate, purified by solid-phase extraction, and analyzed without further sample cleanup. The analytical column is a 3.9 mm×150 mm Waters Symmertry Shield RP18 column and volume fraction of the mobile phase is 50% methanol, 50% water containing 0.1% acetic acid. The results show that the linear range is 0.5-100.0 mg/L except for N-nitrosoanabasine (NAB) from 0.25 to 50.0 mg/L. The limits of detection are 0.1 mg/L for N-nitrosonornicotine (NNN), 0.08 mg/L for 4-(methylnitrosamino)-1- (3-py-ridyl)-1-butanone (NNK), 0.05 mg/L for N-nitrosoanatabine (NAT) and 0.06 mg/L for NAB. The recoveries of the four TSNAs are from 90.2% to 105.7%. 展开更多
