Voice and Heart of Darkness:Centrality and Discourse in Colonialism

My essay on Heart of Darkness explores Conrad’s dramatization of the voice and heart dynamic in the novella as a penetration of the deep-lying rationale of colonial operation and more generally the human condition at the turn of the 20th century.Three different forms of assumed centrality in the novella-capital,Eurocentrism,and the African interior as detrimental void symbolized by the heart of darkness form concentric circles that interconnect and work in concert as the core colonial ideology and produce a sense of incongruity and absurdity.The voice of this colonial ideological apparatus disguised as the universal subject of humanity and rationality finds its best expression in the eloquence of Kurtz,the specimen of culture seduced by its very opposite-the wilderness-right in the heart of darkness.“The horror”,as his final verdict of life as a European with real intent of living on his own terms at the turn of the 20th century,sums up the predicament of a civilization with too much culture and self-absorption for its own good.

Comparison between the Theme of Heart of Darkness and Lord of the Flies

With the discouraging, and horrifying descriptions, Conrad and Golding unanimously present the universal subject matter that at his heart, man is an evil, vicious, and"fallen"being. Furthermore, human being is just susceptible to his own sinister nature. Both Heart of Darkness and Lord of the Flies imply that every man has an evil heart of darkness which is more often than not drowned out by the glow of civilization.

Maintained Exposure to Spring Water but Not Double Distilled Water in Darkness and Thixotropic Conditions to Weak (~1 µT) Temporally Patterned Magnetic Fields Shift Photon Spectroscopic Wavelengths: Effects of Different Shielding Materials

Spring water but not double-distilled water was exposed, in darkness, to a temporally patterned weak magnetic field that has been shown to affect planarian behavior and slow the rate of cancer cell proliferation. Exposure to the magnetic field caused a reliable shift in the peak (longer) wave-length of ~10 nm for fluorescence emissions and a ~20% increase (~100 counts) in fluorescence intensity. Spectral analyses verified a shift of 5 and 10 nm, equivalent to ~1.5 × 10-20 J “periodicity” across the measured wavelengths, which could reflect a change in the an intrinsic energy as predicted by Del Giudice and Preparata and could correspond to two lengths of O-H bonds. Wrapping the water sample containers during exposure with copper foil, aluminum foil, or plastic altered these fluorescent profiles. The most conspicuous effect was the elimination of a ~280 nm peak in the UV-VIS emission spectra only for samples wrapped with copper foil but not aluminum or plastic. These results suggest that weak magnetic fields produce alterations in the water-ionic complexes sufficient to be reliably measured by spectrophotometry. Because the effect was most pronounced when the spring water was exposed in darkness and was not disturbed the role of thixotropic phenomena and Del Giudice entrapment of magnetic fields within coherent domains of Pollack virtual exclusion zones (EZ) may have set the conditions for subsequent release of the energy as photons.

The Conflicts Between Primitiveness and Civilization:an Analysis of Heart of Darkness

Heart of Darkness, a chilling tale of horror set in the Congo during the period of rapid colonial expansion in the 19th century written by the renowned British novelist Joseph Conrad, is a world famous novella. Since its publication, it remains an indisputably classic text and arguably Conrad's finest work. And it has been regarded as a significant text in British literature because of its modernistic features, innovative narration and artistic style. Heart of Darkness deals with the highly disturbing effects of economic, social and political exploitation of European and African societies. It has inspired filmmakers and such authors as F. Scott Fitzgerald, Gabriel Garica Marquez, D. H. Lawrence and Virginia,Woolf. This article is aimed to analyse it from the perspective of primitiveness and civilization. Through the analysis, readers can sense Conrad's attitude towards the two aspects.

Variation of carbon partitioning in newly expanded maize leaves and plant adaptive growth under extended darkness

Plants must maintain a balance between their carbon(C)supply and utilization during the day–night cycle for continuous growth since C starvation often causes irreversible damage to crop production.It is not well known how C fixation and allocation in the leaves of crops such as maize adapt to sudden environmental changes.Here,to quantify primary C fixation and partitioning in photosynthetic maize leaves under extended darkness and to relate these factors to plant growth,maize seedlings were subjected to extended darkness(ED)for three successive days at the 6 th leaf fully expanded stage(V6).ED reduced plant growth and leaf chlorophyll levels but not the rate of net CO_2 exchange.As a result of the reduction in photoassimilates,the accumulation of starch and total soluble carbohydrates(TSC)in mature leaves also decreased under ED.However,the percentage of the daily C fixation reserved in mature leaves increased.These transient C pools were largely composed of TSC and were mainly used for consumption by increased nocturnal respiration rather than for transport.As the days went on,both the amount of C accumulated and the percentage of the daily fixed C that was reserved in leaves decreased,which could be largely accounted for by the attenuated starch synthesis in all treatments.The activities of ADPglucose pyrophosphorylase and soluble starch synthase decreased significantly over time.Therefore,this study concluded that both starch and TSC are involved in the coordination of the C supply and plant growth under a sudden C shortage but that they may be involved in different ways.While the ratio of reserved C to daily fixed C increased to maintain blade function under acute C starvation,both the amount and the proportion of C reserved in mature leaves decreased as plant growth continued in order to meet the growth demands of the plant.

A Research on Darkness Adaptation of Drivers

This paper presents the results of darkness adaptationtest for drivers. It is shown that there is a significant difference ( p <0.05)in their darkness adaptation ability between the drivers in accident group and non-accident group. It is further revealed that the accident rate of the drivers with darkness adaptation time ≤10 s is 2.6%, while that with darkness adaptation time >10 s is 7.3%, implying that the high accident rate of the drivers in accident group might be caused by their longer darkness adaptation time.

On the Three Themes of Heart of Darkness

Heart of Darkness is one of the masterpieces of Joseph Conrad （1857-1924）, which shows the author＇s great humanity and his unreserved horror at the crimes committed by the colonists and imperialists all over the world. This thesis tries to analyze its three themes： the Colonists＇ material essence, the dark side of human nature, and the disillusionment of civilization. Kurtz, the main character in the novel, is characterized by his greed for material gain and power. The dark side of human nature is reflected in Kurtz＇s cruel behavior towards the natives, his sense of superiority to the marginalized, and his dominance in discourse over the colonial people. Along with the colonists＇ crazy behaviors, there is disillusion with the modem civilization.

dark与darkness

形容词 dark 有两个名词,一是 dark,二是 darkness。由于两者在用法上既有相同之处,又有不同之处,造成了实际使用中的困难。因而,对二者的辨异很有必要。现将二者的异同归纳如下:

Sound Narrative of the Suppressed Species in Heart of Darkness

Joseph Conrad in Heart of Darkness calls for the suppressed species on humanitarian grounds.In this sense,this paper aims to dredge how the suppressed species utter their voices of rebellion and form a special soundscape.The African natives make use of unique ways of drumming and shouting,to tell how they are enslaved and how they resist the domination of the British pilgrims.In the meanwhile,the black female also uses voices to rebel against her marginal condition compared to males,including white and her native males.By putting the story’s sound narrative in the framework of ecofeminism,this paper intends to not only disclose the rebellious spirit of those suppressed species,but also raise people’s awareness of caring for the living creatures in the marginal status,including women,the blacks,animals,and the ecological environment as a whole.

The Symbolic Meaning of Color in Heart of Darkness

Joseph Conrad is one of the most influential writers at the turn of 20th century. Heart of Darkness is one of his representative novels which were partly based on Conrad＇ s four-month journey to Belgian Congo in 1890. The plot of Heart of Darkness is simple, but the meaning of the plot is not easy to grasp. The masterpiece bears very strong symbolic colors in the description of the setting and characters, which is worth further research.

Hell of Darkness—Book Review of Heart of Darkness

The article is a book review of Joseph Conrad's novella:Heart of Darkness. In this novella, the author criticizes colonial-ism by telling the story of Marlow and Kurtz. This article analyzes Heart of Darkness from the following aspects:background, charac-terization, symbolization and influence.

Conrad's Heart of Darkness in the View of Postcolonial Theory

As one of the most important and greatest novels of Joseph Conrad, Heart of Darkness, has attracted extensive attention from literature fields in the world and has always been under critics since its publication. This paper,from the perspective of Edward Said's postcolonial theory—Orientalism,aims to analyze this classical work from the following three aspects: distorted description of the nature settings in Africa, distorted description of the image of the Africans as well as the white's blame on Africa for their degeneration.

The "Dark Self" in "The Secret Sharer" and "Heart of Darkness"

Human nature is one of the most thoroughly studied topics in human history.Even today the argument continues in all different social contexts,and by studying Conrad's two stories:Heart of Darkness and The Secret Sharer,the author tries to analyze the two sides of the nature,both good and evil,which are inherent in us humans.In the essay the author explores the two heroes in the stories and tries to prove that only when we realize and admit our capability for the evil,can we make the good and kind side of nature to flourish.

不同超高压处理对DFD牛肉肉色及货架期的影响

为降低DFD(dark,firm and dry)牛肉初始菌落总数,延长真空包装DFD牛肉货架期并改善肉色,以不同压力(200、400、600 MPa)配合不同加压时间(5、10 min)的超高压处理为实验组,以空白处理为对照组,测定真空包装DFD牛肉在(2±2)℃条件下贮藏0、2、4、6、8、12、16 d后的肉色、表观肉色图像、pH值、微生物和3种肌红蛋白相对含量,探究超高压处理对DFD牛肉货架期及肉色的影响,进而探寻适合DFD牛肉肉色改善和货架期延长的超高压处理条件。结果表明:超高压能显著提高DFD牛肉的亮度值、红度值和黄度值(P<0.05),增加氧合肌红蛋白的相对含量,降低高铁肌红蛋白的相对含量,但过高压力(600 MPa)会使DFD牛肉呈现粉红色;超高压处理能显著降低DFD牛肉初始菌落总数(P<0.05),200 MPa(5、10 min)处理组使DFD牛肉初始菌落总数降低0.6、0.8(lg(CFU/g)),400 MPa(5、10 min)处理组降低1.1、1.3(lg(CFU/g)),600 MPa(5、10 min)处理组降低1.7、2.0(lg(CFU/g)),有效抑制了微生物在贮藏期间的生长;对照组在12 d时已腐败,200 MPa处理组在16 d时达到腐败限值,而冷藏16 d,400、600 MPa处理组均未腐败;400 MPa是有效改善DFD牛肉肉色、延长其货架期的最适压力,保压时间的延长对肉色和货架期的影响不显著(P>0.05)。综合考虑,400 MPa-10 min是超高压处理DFD牛肉的最适参数,能改善DFD牛肉肉色,同时将货架期至少延长5 d以上。

Dynamical Dark Energy in Light of Cosmic Distance Measurements.Ⅱ.A Study Using Current Observations

We extract key information on dark energy from current observations of BAO,OHD and H_(0),and find hints of dynamical behavior of dark energy.In particular,a dynamical dark energy model whose equation of state crosses-1 is favored by observations.We also find that the Universe has started accelerating at a lower redshift than expected.

Effect of Cosmic Plasma on the Observation of Supernovae Ia

In observational cosmology,a supernova la is used as a standard candle in order to extend the Hubble diagram to a higher redshift range.Astrophysicists found that the observed brightness of high redshift supernovae la is dimmer than expected.This dimming effect is considered observational evidence for the existence of dark energy in the universe.It should be noted that this conclusion is based on an assumption that the mass density of the cosmic plasma is very small.Therefore,the dimming effect caused by the Compton scattering of free electrons in cosmic plasma can be neglected.X-ray observations suggest that the mass density of the cosmic plasma may be very large.In theory,the observed dimming effect of high redshift supernovae Ia may be caused by the Compton scattering of free electrons in the cosmic plasma.In this paper it will be shown that this idea is reasonable.Therefore,there is no need to introduce the confusing concept of dark energy into cosmology.

PHYTOCHROME-INTERACTING FACTORS Interact with the ABA Receptors PYL8 and PYL9 to Orchestrate ABA Signaling in Darkness

PHYTOCHROME-INTERACTING FACTORS(PIFs)are a group of basic helix-loop-helix transcription factors that can physically interact with photoreceptors,including phytochromes and cryptochromes.It was previously demonstrated that PIFs accumulated in darkness and repressed seedling photomorphogenesis,and that PIFs linked different photosensory and hormonal pathways to control plant growth and development.In this study,we show that PIFs positively regulate the ABA signaling pathway during the seedling stage specifically in darkness.We found that PIFs positively regulate ABI5 transcript and protein levels in darkness in response to exogenous ABA treatment by binding directly to the G-box motifs in the ABI5 promoter.Consistently,PIFs and the G-box motifs in the ABI5 promoter determine ABI5 expression in darkness,and overexpression of ABI5 could rescue the ABA-insensitive phenotypes of pifq mutants in the dark.Moreover,we discovered that PIFs can physically interact with the ABA receptors PYL8 and PYL9,and that this interaction is not regulated by ABA.Further analyses showed that PYL8 and PYL9 promote PIF4 protein accumulation in the dark and enhance PIF4 binding to the ABI5 promoter,but negatively regulate PIF4-mediated ABI5 activation.Taken together,our data demonstrate that PIFs interact with ABA receptors to orchestrate ABA signaling in darkness by controlling ABI5 expression,providing new insights into the pivotal roles of PIFs as signal integrators in regulating plant growth and development.

Sphingosine-1-phosphate (S1P) mediates darkness-induced stomatal closure through raising cytosol pH and hydrogen peroxide (H_2O_2) levels in guard cells in Vicia faba

The role and signaling of sphingosine-l-phosphate （SIP） during darkness-induced stomatal closure were examined in Vicia faba. Darkness substantially raised S 1P and hydrogen peroxide （H202） levels and closed stomata. These darkness effects were significantly suppressed by DL-threo-dihydrosphingosine （DL-threo-DHS） and N,N-dimethylsphingosine （DMS）, two inhibi- tors of long-chain base kinases. Exogenous SIP led to stomatal closure and H202 production, and the effects of SIP were largely prevented by the H202 modulators ascorbic acid, catalase, and diphenyleneiodonium. These results indicated that SIP mediated darkness-induced stomatal closure by triggering H202 production. In addition, DL-threo-DHS and DMS significantly suppressed both darkness-induced cytosolic alkalization in guard cells and stomatal closure. Exogenous SIP caused cytosolic alkalization and stomatal closure, which could be largely abolished by butyric acid. These results demonstrated that SIP syn-thesis was necessary for cytosolic alkalization during stomatal closure caused by darkness. Furthermore, together with the data described above, inhibition of darkness-induced H202 production by butyric acid revealed that S 1P synthesis-induced cytosolic alkalization was a prerequisite for H202 production during stomatal closure caused by darkness, a conclusion supported by the facts that the pH increase caused by exogenous SIP had a shorter lag and peaked faster than H202 levels and that butyric acid prevented exogenous SIP-induced H202 production. Altogether, our data suggested that darkness induced SIP synthesis, causing cytosolic alkalization and subsequent H202 production, finally leading to stomatal closure.
