不为薪水工作

一些年轻人,当他们走出校园时,总是对自己抱有很高的期望,认为自己一开始就应该得到重用,得到丰厚的报酬。他们在工资上喜欢互相攀比,似乎工资成了衡量他们一切的标准。但事实上,刚刚踏入社会的年轻人缺乏工作经验,是无法委以重任的,薪水自然不会很高,于是他们有很多怨言。 也许亲眼目睹父辈们和他人被老板解雇的事实,现在的年轻人往往将社会看得比上一代人更冷酷、更严峻,因而也更加现实。在他们看来,我为公司干活,公司付我一份报酬,等价交换,仅此而已。他们看不到工资以外的东西,曾经在校园中编织的美丽梦想也逐渐破灭了。没有了信心,没有了热情。

The influence of three mangrove species on the distribution of inorganic nitrogen and phosphorus in the Quanzhou Bay estuarine wetland soils

This study aims to investigate the effects of region and three regional dominated mangrove species(Avicennia marina, Aegiceras corniculatum and Kandelia candel) on the distribution of inorganic nitrogen and phosphorus. Measurement of the inorganic nitrogen and phosphorus and enzymatic activities was carried out in soils covered by three mangrove species in the Quanzhou Bay estuarine wetlands, a typical coastal wetland in China.Species with a higher biomass in upstream and midstream absorb more nitrogen from soils, and the retention of the available phosphorus in the soils of different regions causes the regional variation of phosphorus. In areas dominated by A. marina, nitrate nitrogen is lower while available phosphorus is higher. Meanwhile, nitrate nitrogen and available phosphorus are higher in the soils covered by K. candel.Moreover, all three species affect the elemental and enzymic stoichiometry. The mangrove species influences the diversity of the elemental and enzymic stoichiometric relationship through differential microenvironments, which induce the biodiversity of wetland ecosystems. Thus, this study may facilitate a better understanding of the transformation ability of mangroves to nitrogen and phosphorus and will therefore be beneficial for providing a basis for the ecological restoration of estuarine wetlands.

Analysis of Correlational Behavior of Solvent and Insolvent Firms Based on Accounting Ratios

The concept of crisis evolution is still not fully understood, despite over 40 years of research into investigations in the field of crisis and insolvency prediction. This is due to the fact that the financial situation of a firm changes within an unobservable life cycle continuum, comprising different economic states which are not in fact properly defined. The aim of this study was to contribute towards a better understanding of the differences between solvent and insolvent finns for the periods of one and two years prior to insolvency respectively. Through the application of correlation and factor analysis, an attempt was made to detect behavioral pattems in accounting ratios, which can in turn explain differences and similarities between the two groups of finns. The results of this study show that although accounting ratios from two consecutive years had low correlations for both groups of finns, they were much higher for insolvent firms. This provides evidence that the economic and financial situation of insolvent firms is much more dependent on its history when compared to solvent firms. Moreover, there is evidence to suggest that the change of the economic and fmancial situation of insolvent firms within the life cycle continuum tends to follow a predetermined path, in contrast to the more random nature of a solvent firm＇s behavior. Additionally, the results showed that the factor loadings for solvent and insolvent finns differ for both observation periods, indicating that there are different underlying factors affecting the final outcomes for the two groups of firms. This is mainly attributable to disturbances in the scaling factors of total assets for both observation periods, as well as the disappearing size factor for the pre-distress year for insolvent firms, based on factor analysis.

A Comparison of Libyan and Australian Students＇ Perceptions of Empowerment in Accounting Courses

The concept of empowerment was introduced into the accounting education research by Zraa, Imran, Kavanagh, and Morgan （2011）. The authors＇ purpose is to compare Libyan and Australian students＇ perceptions of empowerment in accounting courses and to investigate their relationships with classroom instruction. This study involves a survey of 409 students, who are studying the first-year business degree at institutions in Libya and Australia. Observations and interviews are also conducted. Data are analyzed using reliability tests, factor analysis, t-tests, and correlations. The results indicate that Australian students are more empowered than Libyan students. In addition, the result reveals that classroom instruction methods influence students＇ empowerment.

Ecological stoichiometry of nitrogen, phosphorous, and sulfur in China's forests

Much attention has been paid to the stoichiometry of carbon(C), nitrogen(N), and phosphorus(P) because of their significance for plant growth and climate change. However, other nutrients, such as sulfur(S), are often ignored. In this study, we analyzed the stoichiometry of N, P, and S in leaves of 348 plant species in China's forests. The results show higher N content and higher molar ratios of N/P and P/S in Angiospermae than in Gymnospermae. At the family level, Ulmaceae absorbed more N and P from soils than other families, and Cupressaceae absorbed more S than other families. In addition,except for bamboo and other tropical forests, leaf N and P content of China's forests generally increased from low to middle latitudes and then slightly decreased or plateaued at high latitudes. Plant ecotypes, taxonomic groups, environmental conditions, atmospheric S precipitation, and soil-available N and P significantly affected the distribution and stoichiometry of leaf N, P, and S in China's forests.Our study indicates that China's forests are likely limited by P and S deficiencies which may increase in the future.

Systematic Analysis of Carbon Dioxide Activation of Waste Tire by Factorial Design

In this study, waste tire was used as raw material for the production of activated carbons through pyrolysis. ＇Fire char was first produced by carbomzation at 550℃ under nitrogen. A two tactortal design was used to optimize the production of activated carbon from tire char. The effects of several factors controlling the activation process, such as temperature （.830-930℃）, time （2-6h） and percentage ot carbon dioxide （70%-100%） were investigated. The production was described mathematically as a function of these three factors. First order modeling equations were developed for surface area, yield and mesopore volume. It was concluded that the yield, BET surface area and mesopore volume of activated carbon were most sensitive to activation temperature and time while percentage of carbon dioxide in the activation gas was a less significant factor.

Adsorption properties of CFBC ash-cement pastes as compared with PCC fly ash-cement pastes

Circulating fluidized bed combustion （CFBC） ash can be potentially used as supplementary cementitious materials for concrete production due to its desirable pozzolanic activity. The adsorption properties of CFBC ash-cement pastes were studied, and ordinary pulverized coal combustion （PCC） fly ash-cement pastes were used as control. The water-adsorption and superplasticizer （SP）-adsorption properties of the pastes were evaluated by water demand and UV-visible absorption spectroscopy respectively. The results show that CFBC ash-cement system has greater compressive strength as compared with PCC fly ash-cement system at a given curing age, although the water demand of the former is significantly higher than that of the latter. CFBC ash-cement pastes possess higher adsorption ability of aliphatic SP than PCC fly ash-cement pastes and the adsorption amount increases with an increase in ash replacement ratio. CFBC ash- cement pastes exhibit lower workability with higher slump loss. It is concluded that CFBC ash can be potentially used as supplementary cementitious material in concrete production, but the mix design of CFBC ash concrete needs to be appropriately adjusted. It is suggested that CFBC ash is used for the production of the concrete needing low flowability.

Media Representing Shakespeare： Adaptation, Inter-Textuality, and Gender

Applying the theory of adaptation, Feminism, and Performance Studies, this paper explores the adaptation, inter-textuality, and gender in the three films The Tempest （2010） directed by Julie Taymor, Prospero＇s Books （1991） directed by Peter Greenaway, and Shakespeare in Love （1998） directed by John Madden, referenced to Gnomeo and Juliet （2011）, a cartoon animation. Both films of The Tempest show visual spectacle and technology images by CGI （Computer-Generated Cinematic Graphic Image） effect. The author argues the power struggle between Caliban and Prospero played by actress Helen Mirren, changes from post-colonial discourse in the male domain, to be more about the intellect contest between man and woman, and Taymor＇s adaptation is more focused on maternity than actor John Gielgud＇s on politics. Inter-textuality exists in Shakespeare in Love and Shakespeare＇s Romeo and Juliet, and Twelfth Night. Unlike the tragedy in the films, Gnomeo and Juliet ends happily as we can expect from most musicals and fairy tales. The inter-textuality of literature and art, dramatic plays, historical events, and biographical sketches are delicately intertwined. Media represent Shakespeare applied by Jean Baudrillard＇s ＂simulacra＂ and Richard Schechner＇s ＂simulation＂ to present the liminal threshold between reality, role-playing, and theatricality. Shakespeare represented by media rise to visual narratives.

Modeling the contribution of the microbial carbon pump to carbon sequestration in the South China Sea

The two key mechanisms for biologically driven carbon sequestration in oceans are the biological pump(BP) and the microbial carbon pump(MCP); the latter is scarcely simulated and quantified in the China seas. In this study, we developed a coupled physical-ecosystem model with major MCP processes in the South China Sea(SCS). The model estimated a SCSaveraged MCP rate of 1.55 mg C m^(-2) d^(-1), with an MCP-to-BP ratio of 1:6.08 when considering the BP at a depth of 1000 m.Moreover, the ecosystem responses were projected in two representative global warming scenarios where the sea surface temperature increased by 2 and 4°C. The projection suggested a declined productivity associated with the increased near-surface stratification and decreased nutrient supply, which leads to a reduction in diatom biomass and consequently the suppression of the BP. However, the relative ratio of picophytoplankton increased, inducing a higher microbial activity and a nonlinear response of MCP to the increase in temperature. On average, the ratio of MCP-to-BP at a 1000-m depth increased to 1:5.95 with surface warming of 4°C, indicating the higher impact of MCP in future ocean carbon sequestration.

Dominant roles but distinct effects of groundwater depth on regulating leaf and fine-root N,P and N:P ratios of plant communities

Aims As the determinant of water availability in drylands,groundwater plays a fundamental role in regulating vegetation distribution and ecosystem processes.Although considerable progress has been made over the past years in the relationship between environment stress and plant community-level traits,the potential influence of water stress induced by groundwater changes on plant community-level stoichiometry remains largely unclear.Here,we examined whether belowground and aboveground community-level stoichiometry responded differently to groundwater changes.Methods We measured nitrogen(N)and phosphorus(P)concentrations in plant leaves and fine-roots of 110 plots under a broad range of groundwater depths in a typical arid inland river basin.We examined the spatial patterns and drivers of community-level N:P stoichiometry in leaves and fine-roots.Important Findings Community-level leaf and fine-root N,P and N:P ratios were mainly determined by groundwater,vegetation types and species composition,among which groundwater played a dominant role.Groundwater indirectly regulated community-level N:P stoichiometry through affecting vegetation types and species composition.Vegetation types and species composition had significant direct influences on communitylevel N:P stoichiometry.Furthermore,groundwater depth had opposite influences on community-level leaf and fine-root N:P stoichiometry.Groundwater depth regulated vegetation types and further decreased leaf N,P but increased leaf N:P ratios and fine-root N.Groundwater depth had a positive indirect impact on fine-root P but a negative indirect impact on fine-root N:P ratios primarily by affecting species composition.Our findings indicate that groundwater rather than climate conditions effectively regulates community-level N:P stoichiometry,and below-and aboveground N:P stoichiometry has opposite responses to groundwater.

Curing the fundamental issue of impurity phases in two-step solution-processed CsPbBr3 perovskite films

Inorganic lead halide perovskite CsPbBr3 offers attractive photophysical properties and phase stability for high-performance optoelectronic devices.However,CsPbBr3 films produced by the classic solution-based two-step method are always accompanied with impurity phases of CsPb2Br5 and Cs4PbBr6,which represents a major efficiency-limiting factor for future advances of CsPbBr3-based devices.The challenge lies in the complexity of the Cs-Pb-Br phase system,requiring both spatially and temporally precise control of the precursor stoichiometry during solution-phase growth of CsPbBr3 films.By adopting 2-methoxyethanol as the solution conversion medium instead of commonly applied methanol,the reaction between CsBr and PbBr2 can be finely controlled to yield single phase CsPbBr3 films within a few minutes;extending the solution-conversion step to 24 h does not alter the phase purity of resulting CsPbBr3 films.The present work paves the way to regulate the crystal growth behaviors of two-step solution-processed CsPbBr3 films by simple solvent engineering.
