There are two different types of oils—high-wax oil and normal oil—found in the Damintun Depression of Liaohe Oilfield after several years of exploration and development, but their distributions and origins had confused the explorers in the oilfield. The introduction of petroleum-system concept shifts the view of geoscientists from geology and geophysics to oil, gas and their related source rocks. After detailed study, two petroleum systems have been identified in the Damintun Depression: (1) the ES42-Ar buried hill petroleum system (called the high-wax oil petroleum system) and (2) the ES41 ES34-ES4 and ES3 petroleum system (called the normal oil petroleum system). Based on the detailed analysis of the basic components, and all the geological processes required to create these elements of the two petroleum systems, it is put forward that targets for future exploration should include the area near Dongshenpu-Xinglongpu and the area near the Anfutun Sag. This provides scientific basis and has theoretical and practical meaning for the exploration and development. 相似文献

This study examined four questions: (1) How does family structure (specifically, single parenthood, married parent, and cohabitating parent) affect children's delinquency and math test scores? (2) Do these effects differ by race? (3) Do parenting practices mediate the links between family structure and children's outcomes? and (4) Does this mediation differ by race? Unlike some previous work in this area, the present study distinguished between the effects of single parenthood and cohabitation. Using fixed-effects techniques to control for unobserved heterogeneity between children in the various family structures, single parenthood was found to be associated with reduced well-being among European American children, but not African American children. Cohabitation was associated with greater delinquency among African American children, and lower math scores among European American children. No evidence was found to indicate that parenting mediated the links between family structure and children's outcomes. Finally, it was found that for African American children, measures of maternal warmth and the provision of rules had direct effects on children's delinquency. 相似文献

In When Work Disappears, William Julius Wilson argues that the difficulties black inner-city residents face in finding work has more to do with their failure to acquire the kinds of education, skills, and work habits required by changes in the urban labor market than with racial discrimination. In this essay, I argue that this notion tends both to obscure the substantial gains African-Americans have made in education and to discount the degree to which race continues to mediate the relationship between educational achievement and labor market outcomes. Although there is no question that the economic position of those with little education has deteriorated badly over the last two decades, absent policies that address the persistent racial disparities in employment, reforming education by itself will not substantially improve African-American employment opportunities or reduce black joblessness in the inner city. 相似文献

In this paper, we try to examine the classical sociological points of special education, especially the organizational form of special education, social background of students and the minority status of students. The material of the study was collected mostly during 2003 from one large city in Finland. This city has more than a 100‐year‐long tradition of organizing special education, and it is also still organized very traditionally, that is mainly in special schools. The oldest functioning special education school was founded in 1901. This form of organization based on special schools is no longer typical in Finland. Over 1000 questionnaires were sent to special education school teachers, and students and their parents, as well as to special needs assistants. The percentage of returned responses was between 70% and 80%. Local material is practically the only way to get information of these critical points because of the Act on the Protection of Privacy and the administrative orientation of state statistics. The results show that boys are strongly over‐represented in special education. Over three out of four of the students in classroom‐based special education are boys. According to our comparison, the children from immigrant families account for less than one out of ten students in general education, but in classroom‐based special education they represent nearly 14%, and in part‐time special education as much as one‐quarter (25%). The form of education differs also in regard to the social class of the parents. The parents have been divided into upper, middle and lower social classes according to their occupation. The proportion of upper‐class parents of the student group in general education (42%) is doubled when compared to the parents of both special education groups. The majority of the parents of severe disabled students support the idea of special education schools, but the majority of the parents from the other special education groups are in favour of education in the nearest school. 相似文献

Particle pollution in air, also sometimes known as fine dust contamination, may cause electric contact failure. Recent research further proved that the fine particle is becoming a major disruption of the electronic connectors in signal transmission system. This paper specifies the connector contact in mobile phone application. To study the contact failure of mobile phone, a series of inspections and analytical research methods are introduced. Special features that cause the contact failure are summarized. Particle accumulation is the main problem; organic material such as lactates from sweat of the human body may act as adhesives to stick the separate particles together and make them adhere on the contact surface; chemical properties of dust cause serious local corrosion. The corrosion products may trap the particles and firmly attach on the contact surface; micro motion frequently occurs at the contact interface. Hard particle can be embedded into the surface, and soft particle could be squeezed and inserted into the contact; silicon compounds in dust play the most important role in forming high resistance regions that lead to failure; deposition of particles depends on the amount of materials, static electricity attracting force and gravity force applied on the particles. Current dust test can hardly reflect the serious contact failure. It is difficult to simulate the complexity of contact failure caused by particle contamination. Thus alternative ways of simulation experiment and improvement of contact reliability are proposed. 相似文献

Salinger’s the Catcher in the Rye has aroused various disputes after its publication.Either standing on the bestseller list or got banned from reach of juveniles,the book could hardly define a definite position for long.A lost hero with the low-pitched author offered the work to the world without much comment or declaration against vicious criticism.However,read within a certain historical environment,ignoring the content which may have triggered positive or negative responses from the society,the work well explains its intension of expression as well as a function calling for caution.Holden’s mind originates from that contemporary world,manipulated by the postwar Salinger who has got a full brain of mind.The degenerated anti-hero is the outcome of both the outer society of decaying and inner complex of childhood innocence.This essay is going to analyze the above mentioned aspects to better understand the meaning of the Catcher in the Rye,a certain work within a certain social background,which may provide some constructive methods in interpreting works under different environments. 相似文献

Bullying within academia often focuses on peer bullying or the student victim. However, the student bully who targets professors is a neglected area of study yet just as destructive, demeaning, and intimidating. Using a narrative lens analysis, the researchers share how the story of bullying unfolds in the classroom. Distinct triggers, such as entitlement or expectation management, mark the beginning of the narrative. As the narrative progresses, students display a variety of aggressive behaviors in an attempt to establish power or dominance over the targeted professor. The resulting academic contrapower harassment (ACPH) display may negatively impact the professor psyche, learning environment, and overall level of satisfaction with the professoriate, leaving a potentially open-ended narrative that impacts targeted professors for years to come. Thematic analysis reveals shared themes among targeted professors, indicating bullying is problematic on multiple levels. The findings suggest a lack of formal training and education while reinforcing the importance of peer networks. 相似文献

This article surveys the history of compulsory education for soldiers’ career advancement in the British army. It begins with an examination of the organisational context before analysing the rationale, syllabus, teaching and assessment of soldier education. It concludes that for members of the army education organisation their self‐perception as soldiers and educators is of crucial importance; that the justifications for soldier education have been debated constantly between the ‘liberal’ and ‘utilitarian’ groupings within the organisation; and finally that significant work remains to be done in this nexus between British military and educational history. 相似文献

The paper uses time series data constructed from the annual General Household Survey to examine the impact of increasing qualifications, rising unemployment and growing government intervention on the labour market experiences of young people in Great Britain from 1974 to 1981. The data show that for those not continuing in full‐time education the rise in qualifications has been at the lower levels only. For young males growing unemployment after 1979 was associated with a loss of jobs at all skill levels, but the proportion in skilled manual jobs fell steadily throughout the period. For females growing unemployment was associated in the early part of the period with a loss of skilled white collar jobs and in the later part with a loss of less skilled jobs. The decline in the proportion in skilled jobs was particularly marked for the unqualified. While falling unemployment in 1978/79 brought more skilled jobs for 16‐year‐olds, including the unqualified, older teenagers gained only a rise in the proportion in less skilled jobs. Since 1979 the qualifications of young people in skilled manual occupations have risen faster than in other occupation groups. Some implications of these trends are discussed. 相似文献

We studied the geochemical characteristics of the fluid inclusions in the Ordovician carbonates and the Oligocene Shahejie Formation sandstones from 15 wells in the Gangxi Fault Belt, Huanghua Depression. The fluid inclusions are all sec- ondary with gas/liquid ratio of 5%~10%. Base on Raman they are mainly composed of H2O, CO2 and CH4. The homogenization temperatures, combined with burial and geothermal history of the host rock, indicate that the fluid flows in the Shahejie Formation and the Ordovician carbonates were trapped in Neocene. Using a VG5400 mass spectrometer, the helium isotopic compositions were analyzed. Interpretation of results suggested a significant amount of mantle-derived helium mainly accumulating in the intersections of the NWW trending Xuzhuangzi and NE trending Gangxi faults. The maturity of hydrocarbon decreases from the intersection to the outside pointing out that the fluid related to the NWW trending Xuzhuangzi and NE trending Gangxi faults. These factors implied the fluid inclusions have a close relationship to the local tectonic setting. Gangxi Fault Belt experienced intensive Neo-tectonic activities in Cenozoic. Widespread faulted-depressions and strong volcanic eruptions manifested its tec- tonic status of extensional stress field. Mantle uplift caused the movement of magma that carried mantle-derived gases and deep heat flows, the deep-rooted tension faults provided the passages for the gases and heat flows to shallow crust levels. 相似文献

The Bologna Process is an important factor which has had an impact on higher education in Europe. In this paper the implementation of the Bologna Process in Poland, the Netherlands and Flanders is discussed, to show how the different contexts influenced its realization. In order to study the transformation of higher education, new institutionalism and resource dependence theory were applied. Research focuses on six case studies – different universities, which are seen as organizations operating in a specific context and which respond to changes in this context. 相似文献
