Electrochemical Impedance Spectroscopy Study

Electrochemical Impedance Spectroscopy Study Electrochemical impedance spectroscopy An EIS study was carried out at different dc potentials in order to study the mechanism of ORR in O2 saturated alkaline solutions on prepared GDEs. The Nyquist plots of GDEs under different polarization potentials are shown in Fig. 5. The impedance diagrams show two different behaviors which depend on the applied dc potentials. In the other words, the shape of plots changed at different potentials, suggesting different electrochemical processes occurring on the electrode. The impedance spectra acquired at the potential lower than 0.7 V show one loop in the high frequency region associated with the time constant of a charge transfer process and semi-infinite diffusive manner related to Warburg component in the low frequency region. This semi-infinite diffusive character is related to the adsorption of reactants and intermediate products. The Nyquist plots of O2 reduction on GDEs at the E≠¥0.7 show two loops. The processes that could be involved on the electrode surface that would produce these changes include [37]: (1) Diffusion of O2 through the gas phase in the pores (of porous carbon supported catalyst) and the electrolyte to the reaction site. (2) Adsorption or heterogeneous surface reaction of the oxygen, together with oxygen diffusion. (3) Charge transfer. (4) Diffusion of reduction products into the bulk electrolyte Many reaction mechanisms have been proposed to describe ORR in aqueous electrolytes. Among these models, the Damjanovic model (Fig. 6) is one of the most extensively employed models, due to its applicability over a wide potential region. Damjanovic model describes the ORR as a multi-electron reaction which O2 molecules in the vicinity of the electrode are irreversibly reduced directly to H2O through 4-electron transfer (with a constant rate, k1) or to H2O2 through 2-electron transfer (constant rate, k2). The H2O2 formed can be reduced to H2O through 2-electron transfer (constant rate, k3) or diffuse into the bulk solution [38]. The ORR mechanism on transition metals has also been investigated by theoretical calculation based on the electronic structure [39-40]. The dissociative mechanism and the associative mechanism are proposed for a low current density range (more positive potentials) and a high current density range (more negative potentials), respectively [41]. Dissociative Mechanism (E≠¥0.7 V): In this mechanism, no H2O2 is produced. On a metal surface, O2 adsorption breaks the O-O bond and forms adsorbed atomic O, which further gains two electrons in the two consecutive steps, forming hydroxide ions. Since there is no adsorbed O2 on the catalyst surface, H2O2 cannot be formed. This mechanism can be considered a detailed form of the direct 4-electron pathway and can be written as follows: 1/2O2 + M(metal active sites) → O ºads (11) O ºads + e + H2O → OHads + OHaq (12) OHads + e → OHads → OHaq (13) Associative Mechanism (EË‚0.7 V): Since adsorbed O2 is present, the O-O bond may not be broken in the following steps, resulting in the formation of H2O2. The H2O2 could either be further reduced to H2O or be a final product. Therefore, the mechanism can be written as follows: O2,ads + 2H2O + 2e → H2O2 + 2OH (14) H2O2 + 2e → 2OH (15) The further reduction of H2O2(ads) to hydroxide ions occurs only once the enough overpotential has been reached and before the formed H2O2 diffuse into the bulk solution [41]. The two loop manner of GDEs in Nyquist plots may be related to two basic steps. On the other hand, for E ≠¥ 0.7 V, two time constants are detected during the impedance measurements (Fig. 5). The first time constant at high frequencies is associated with the charge transfer reaction according to Eq. 12, while the second may be associated with the further reduction of OHads to produce OH based Eq. 13. On the other hand, for EË‚0.7 V, the first time constant is related to H2O2 intermediate formation according to Eq. 14 and further semi-infinitive diffusive manner in the low frequency region can be explained by adsorption and diffusion of this intermediate into the bulk solution. In order to obtain quantitative information from impedance spectra in Fig. 5, two electric circuits were employed (Fig. 7). The electric circuit in Fig. 7a was used to simulate the impedance response of those spectra with OCP and E Using the equivalent circuits shown in Fig. 7, a constant phase element (CPE) is suggested instead of pure capacitance (C), due to the non-homogeneous surface of the electrodes. The impedance of CPE is defined as [Yo(jω)n]-1, where Yo is a constant with dimension (S.sn), while the exponent n denotes the correction factor pertaining to the roughness of the electrode and has values that range from 0 to 1. A pure capacitance yields n=1, a pure resistance yields n=0, while n=0.5 represents the ideal Warburg impedance. The true capacitance values can be calculated using the following equation [38]: C=[Yo Ãâ€" R (1-n)]1/n (14) According to equivalent circuits shown in Fig. 7, Rs is associated with the resistance of the solution, connectors, leads and wires. R1 is the charge transfer resistance of the reduction process from O2 to H2O2, R2 is the resistance of adsorbed species with H2O2 as the main intermediate or O2 adsorption into the GDE pores in the figure 7.a. The R1 and R2 circuit components in figure 7b are the charge transfer resistance of the reduction process of O ºads to OHads and the reduction process of OHads to OH, respectively. Parameters calculated from the equivalent circuits (Fig. 7) of O2 reduction on the GDEs are listed in Table 3. According to table 3, the Rs values change as a function of the potential, indicating that the contribution of the apparatus (connectors, leads and wires) from the total impedance of system shouldn’t be dismissed. So, the Rs values have a contribution function of both electrolyte and the apparatus resistance, i.e., connectors, leads and wires. R1 and R2 also show a dependence on the applied dc potentials (Fig. 8). By increasing the positive potential, the R1 values decrease. In the potential region of lower than 0.7 V, the adsorption of free O2 molecules happens on the metal catalyst and then O2,ads reduces to OHads (Eq.8). In the applied dc potential of E≠¥0.7 V, the adsorption of O ºads free radicals happens. By increasing the positive applied potentials, the adsorbed amount of O2,ads and O ºads increases and the further reduction process occurs more easily in the catalyst layer. So the R1 values will be decreased. The dependence of true capacitance values of the applied potentials is shown in Fig. 10. The adsorbed species enhancement by increasing the more positive potentials causes to decrease of C1 values. The R2 values for EË‚0.7 V are related to the adsorption of molecules like H2O2,ads into the GDE pores. When the potential is increased to more positive potentials, the adsorption of H2O2,ads spec ies by the oxygen atom orientation to the metal catalysts will be increased and R2 values became higher. In the potential region of E≠¥0.7 V, the OH,ads species which are reduced to OHaq, increase and charge transfer happens more easily. So the R2 values will be decreased. The C2 values also decrease because of more species adsorption (Fig. 10). Comparison of R values for GDEs shows that the Pt.Ru/C electrocatalyst has the lowest resistance in the whole range of applied dc potentials because of charge transferring occurring more easily and so ORR happens more rapidly at this electrocatalyst type. This behavior can be observed due to the synergistic effects of Pt and Ru catalyst species. The true capacitances of GDEs also show that the calculated of Pt.Ru/C and Ru/C electrocatalyst are higher than Pt.C ones. It is because the Ru species act as a protonic capacitor in the Pt.Ru/C and Ru/C GDEs. 3.5. Chronoamperometery The oxygen diffusion coefficients of GDEs were determined by chronoamperometry technique. Chronoamperograms were obtained by holding the potential of the electrodes at +1.2 V for 10 s and then holding it at +0.4 V relative to the Ag/AgCl electrode for 500 s with oxygen flowing along the electrolyte. With plotting i vs. t−1/2, the linear dependence relationship was obtained for different electrodes [42]: (16) Where I is the limited current, A the surface area of the electrode, D the diffusion coefficient, C the concentration of oxygen, n the number of electrons in the overall reaction of ORR, F the Faraday’s constant, t the time, and à ¯Ã‚ Ã‚ °Ãƒ ¯Ã¢â€š ¬Ã‚  is equal to 3.14. Fig. 11 shows the chronoamperograms of GDEs at +0.4V in relative to the Ag/AgCl in alkaline media. . Cottrell parameters are listed in Table 4, also. The results confirmed the higher Cottrell slope and D values for Pt.Ru/C electrode. So, the Pt.Ru/C cathode has more permeability and activity towards oxygen reduction reaction. Conclusion In this investigation, Pt/C, Ru/C and Pt.Ru/C bimetallic electrocatalysts were prepared by chemical reduction process. Then the resulted inks were coated on carbon paper and used as gas diffusion electrodes for oxygen reduction reaction in alkaline media. The surface structure of oxygen depolarized cathodes was studied by SEM and EDX analysis. The SEM results showed that all the cathodes consist of rough and porous structures. And Pt, Ru nanclusters were deposited quite uniformly onto/into Vulcan carbon supports with the average particle size of about 30-45 nm. The ORR activity of cathodes was evaluated in 0.1 M O2 saturated NaOH media. Comparison of cyclic voltamograms of Pt/C, Ru/C and Pt.Ru/C electrodes in O2 saturated solutions show that for Pt.Ru/C catalyst current increase induced by ORR is shifted towards more negative electrode potentials and only higher current values have been obtained within the ORR region. It can be concluded that the second metal addition has influenced the catalytic activity of electrocatalyst toward ORR. This matter can be related to synergistic effect, which is playing a critical role in ORR activity. The Pt.Ru/C cathodes showed lower Tafel slops and high current densities. An EIS study was carried out at different dc potentials in order to study the mechanism of ORR in O2 saturated alkalin e solutions on prepared GDEs. The Nyquist plots of GDEs under different polarization potentials show two different behaviors, suggesting different associative and dissociative electrochemical processes occurring on the electrode.

A Man For All Seasons Essays -- essays research papers

The 16th century was a time of political upheaval, a time of conflict and corruption †¦ and a time of heroes? All these elements are visibly present in Bolt’s book, A Man for All Seasons. As I was reading this story I was thinking that it could probably apply to our day and age but that begged the question. Why did Robert Bolt decide to use a 16th century character rather than a present time period character and setting? I believe that Bolt chose this man and his era because there things that he liked abut the man, there was no shortage of conflict and the he was worthy of being a hero. He fits into one of the archetype heroes. These three things I will touch upon in my seminar and I hope that my ideas will prove to be informative and enlightening.   Ã‚  Ã‚  Ã‚  Ã‚  One of the main reasons that Robert Bolt probably chose 16th century Thomas More as his hero for A Man for all Seasons was that he liked his personality. By that I mean that as Bolt wrote about More, he discovered more and more things that he found admirable about the man. At the outset, Robert Bolt was looking for a person who had a strong idea of who he is because this is what Bolt thinks is necessary to be a hero and this is exactly the type of man that Thomas More is. More saw in himself something that was his only and he was that it was something that allowed him to live life with confidence in himself. Only when he was denied that way of life was he able to accept his fate of death. Robert Bolt comments on this on page 13 of the preface. â€Å"†¦who nevertheless found something in himself without which life was valueless and when that was denied him, he was able to grasp his death.† This shows that Thomas knew that he had a sense of identity that no one else and he knew how important it was.   Ã‚  Ã‚  Ã‚  Ã‚  After Robert Bolt selected this man, he began to write and realised many more things about Thomas More, which had drawn him to the 16th century character. One of the things that Bolt found out was More’s sense of self. He remarks on this on page 12 of the preface. â€Å"At any rate, Thomas More, as I wrote about him, became for me a man with an adamantine sense of his own self.† Robert Bolt went back to this era long past because of that trait but it was as he wrote about him that he discovered just how strong his sense of identity was.   Ã‚  Ã‚  Ã‚  Ã‚  B... ...e me, Alice, that in silence is my safety under the law, but my silence must be absolute, it must extend to you.† (P56) He has found that so long he doesn’t give any indication to his opinion, hey cannot do anything to him legally. â€Å"MORE: There’ll be no trial, they have no case.† (P85) When he is asking his family to leave the country, he knows that he has protected himself to the best of his abilities. He should be safe except for the fact that he is dealing with a corrupt King who considers himself above the law.   Ã‚  Ã‚  Ã‚  Ã‚  Is there any way to do a play such as this in the 20th century? Evidently, Robert Bolt thought not and after analysing the story further, I have come to realise that he is right. The elements of the story, which were present in the 16th century, are not present in the 20th. There also may have been no one in this century that Robert Bolt liked enough and with the right characteristics. And of course, there is not enough conflict for one man to face as there was in that time. I believe that there are men (And women.) who would be able to face the problems that Thomas More had to face but we can all be thankful that there is no need for it.

A Raisin in the Sun and Brown versus Board of Education :: Race Racial Segregation Lorraine Hansberry

The American Dream Langston Hughes wrote a poem, in 1951, called â€Å"Harlem†. It sums up the play A Raisin in the Sun, by Lorraine Hansberry: â€Å"What happens to a dream deferred? Does it dry up like a raisin in the sun? Or fester like a sore- and the run? Does it stink like rotten meat? Or crust and sugar over- like a syrupy sweet? Maybe it just sags like a heavy load. Or does it explode?† Lorraine Hansberry uses this poem to open A Raisin in the Sun. This dialogue suggests what happens to the African American’s dream during the Brown v. Board of Education trials. While critiquing this play I was a little disappointed that Brown v. Board of Education was not discussed directly. However, I did find the plot of the play, and the people who were attending it to be very interesting. The plot of A Raisin in the Sun does not directly talk about the Brown v. Board of Education decision. Actually, very little of the play, until the end, deals with any kind of racial segregation. The play revolves around four main characters; Walter, a defiant husband who desperately wants to become rich; Ruth, Walter’s devoted wife; Beneatha, Walters intellectual younger sister, who is much better educated than the others and wants to become a doctor; and Mama, the head of the household, and also Walter and Beneatha’s mother. Mama inherits some money from her dead husbands insurance. With this money she buys a house in an all white community, and gives the rest to Walter. He is instructed to put some money away for Beneatha’s medical school, and the rest into a checking account for himself. Walter, however, desperate to become rich foolishly gives the money to his friend to invest in a liquor store. His so called friend runs off with all of the money Walter gave him. In order to get some money back for Beneatha to go to school, Walter wants to sell the house back to the white community. The community offered the Younger family a lot of money for the house, because they did not want Negroes living next to them. In the end however, Walter, realizes that it is this house that unifies the family and is what truly will make them happy, instead of being rich.

Duty of care Essay

1.1 â€Å"Duty of care† means to provide care and support to individuals within the law and also within the policies, procedures and agreed ways to work. It is about keeping the service users independence, to support and enable them to live within an environment free from prejudice and safe from abuse. Everyone is entitled to their own opinions, choices and we should respect that at all times while promoting them as an individual. 1.2 By working within standards set out and within our own capacity we will prevent harm from occurring to ourselves, others and the individual. By giving an individual choice and respecting their views/wishes they know that their independence has not been taken from them, giving them more confidence if an issue of safeguarding etc. were to arise. To understand and be able to pass on the procedures in place if we are suspicious or aware of abuse, an individual being endangered or poor work practice by another carer or agency. Reporting, recording are the steps needed to ensure that any form of safeguarding or protection issues are dealt with immediately and correctly. 2.1 While working in care, the aim is to give the best possible standard of care to service users, but sometimes there can be a conflict beetween the individual’s or their family’s wishes and rights and the duty of care. In this case the most important thing is to decide whether the person is aware of the risks and consequences of the decision and has the capacity to make the decision. Before taking best interest decisions I have to make sure that the person definitely lacks the capacity. The person or their next of kin has an overall right and responsibility in decision making for issues relating their care, and I need their consent to deal with certain issues. When a dilemma arises, my responsibility is to support individuals or their families to make informed choices. Even if I disagree with their decision, I can only give advice but can not force them.

Business Practice in Australia

Some rural communities will not have the same exposure to immigrants and international visitors, although the popularity of Australia as a budget traveler destination has affected that. Generally variety is accepted and people of many cultures will be seen in the workplace and are accepted. (Source 3) Source 3: Cultural Dimension and Concept Hoofed Background to Business in Australia Book Author: Egger The country is very large with smallest amount of population compared to land area though has equally states of USA relatively has a population half the size of California.Due to lack of domestic market in size compared to geographic isolation which means Australian business increasingly recognize the need of international market to ensure their future country income as well as well being of country. Indeed, a criticism that has been leveled against Australian business organizations has been their slowness to take up the challenge of international. Source 4) Thus, Australia finds itsel f needing to become ever more international in its outlook both economically and politically.The extremely successful economy is dependent upon trade with both the US and increasingly with key Asian countries such as China, Japan and India. Traditional British Commonwealth links have been declining in importance over several decades. ( Source 4) In short Australia is a small market with a highly educated, affluent population which realizes the importance of international trade – they are waiting to do business with you! ( Source 4) Australian Business Structures people do not give the impression that they ‘think they are somebody'.It is much better to be seen as a ‘good bloke' or a ‘good mate' than somebody who is overtly proud of themselves and their achievements. Australian business thinking is based on US business modeling where people would have conflict with influence to be slavish with others who are in favor of US style entrepreneurial. ( Source 5) Th ese dispute combination leads Australian organization to be fairly non-hierarchical in their structure. Attention is paid to titles and ranking with the organizations. Thus NY integration organization looking to set up operation in country should be well advised against their behavior of business structure.Similarly, do not be too surprised if Australian business contacts seem willfully disrespectful of hierarchy when working internationally – they are not being rude, merely acting in a consistent Australian manner. ( Source 5) (Source 4 & 5: Horticulturalists. Com/ Australian Business Structure. HTML) Australian Management Style It is believe in Australia that in work everyone is Just having different Jobs not as in terms of different position, therefore manages are not expected to see themselves as n any way superior to their colleagues.Such approach may provoke outright hostility. Challenging the idea of boss in open meeting is not at all consider as rude or disrespectful on contrary it is found as committed or an professional approach, therefore it is compulsory to adopt consultative style of management which is inclusive of person's opinions or an open debate of ideas. In keeping with the Australian direct style of communication, debates between senior and Junior executives may appear from the outside as confrontational and occasionally they rarely are.This style of interaction is merely viewed as the most acrimonious ? effective way of attaining the end goal. ( Source 6) Australian managers to not remain aloof from members of their team ? they usually want to be ‘one of the boys' and be seen as ‘a good bloke'. The idea of managers only socializing with other managers would be viewed as very affected and would be likely to result in alienation. ( Source & 6: Horticulturalists. Com/Australian Management Style) Australian Meetings Australian do considered punctuality as virtue, however meeting often start five or ten minutes late.In addit ion, it has tradition to go through few minutes of small talk fore getting down to serious discussion of meeting where sport is considered as common theme of discussions. Post planning culture is very well known in Australia prior to client facing meetings where little preparation is done before to attend such meetings. As an egalitarian approach, Australian are often set as an forum for open debate of an issue during meeting and found professional in doing so.Being ‘over- prepared' for meetings can result in certain negative feelings towards those who have prepared in advance as they can be seen to be trying to dictate and force their ideas on other people. If something important arises during the open debate it will not be excluded simply because it does not occur on the agenda. ( Source 7) Source 7 : Horticulturalists. Com/Australian Meetings Australian Team Australian looks for those who are very good as team player and has extreme importance according to their psyche wher e as Loner or invariable person not considered as good team person.Food and drinks are actively encouraged during make themselves out to be better than their colleagues in workplace does not make a good team player. A competitive edge should be directed towards the other am' (the competition) rather than being internally focused. ( Source 8: Horticulturalist. Com/ Australian Team) Australian Communication Styles Although Australia is resided with many different people from parts of world with over 100 languages being spoken by those population who have emigrated there, English is the official and by far most commonly spoken language.Directness is cherished in Australia and failure to say what you mean and mean what you say can be mistaken for evasiveness and even hypocrisy. ( Source 9) It is important not to be too self-promotional when presenting to Australians. A hard sell approach can often be misconstrued as bragging and can provoke a very negative response. Remember that people do not like to make out that they are better than others ? the same probably applies to products and services. A factual description of issues will be far better received than a more hyperbolic approach. Source 9) First names are invariably used in all business situations in Australia. It would be very unusual to call a business contact by their surname. Similarly, educational titles play relatively little part in business situations. (Source 9: Horticulturalists. Mom/Australian Communication style) Women in Business in Australia Women currently make up a large percentage of the workforce but as in many other countries are often found in lower paid and part-time Jobs. Whilst progress is being made, statistics will show that women are still paid comparatively less for doing the same Job as a man.On the other hand, women have made more progress in attaining managerial positions than in many other leading industrialists nations and more and more women are reaching the highest levels o f Australian organizations. (Source 10) :horticulturalists. Mom/ Women in business in Australia Australian Dress Code In corporate Australia, standard business dress is still very much the norm. Dark suits and ties are the standard dress for management level businessmen with women wearing business suits with either skirts or trousers.Remember that, for much of the year, Australia is a very hot country – so make sure that your clothing is lightweight and cool during those periods. Try to avoid excessive Jewelry and accessories which may be viewed as too ‘flashy' and therefore unprofessional. ( Source 1 1 : Horticulturalists. Mom/Australian dress code. HTML) Australian Etiquette & Customs ( Source 12) Meeting Etiquette Australians are not very formal so greetings are casual and relaxed. A handshake and smile suffices. While an Australian may say, ‘Giddy' or ‘Giddy, mate', this may sound patronizing from a foreigner.Visitors should simply say, ‘Hello' or ‘Hello, how are you? ‘ Gussies prefer to use first names, even at the initial meeting Gift Giving Etiquette Small gifts are commonly exchanged with family members, close friends, and neighbors on birthdays and Christmas. Trades people such as sanitation workers ay be given a small amount of cash, or more likely, a bottle of wine or a six-pack of beer! If invited to someone's home for dinner, it is polite to bring a box of chocolates are opened when received. Dining Etiquette Many invitations to an Gussies home will be for a ‘Barbie' (BBC).Guests to a barbeques typically bring wine or beer for their personal consumption. In some cases, very informal barbecues may suggest that you bring your own meat! Arrive on time if invited to dinner; no more than 15 minutes late if invited too barbeques or a large party. (Source 12: Kiss, Bow, Shake hand , Page 25-26) Successful Entertaining in Australia There is no great tradition for business entertaining in Australia and it ce rtainly shouldn't be viewed as the quick way to cement relationships with a new client or contact.In fact, you are more likely to be asked out for lunch or dinner once a firm relationship has been established – in this way the meal can in no way be seen to have influenced a business decision. People will very often ‘go Dutch' over a meal – this means that the bill is split equally amongst those present at the meal. If you wish to pay, make sure you make this clear before the meal to avoid any embarrassing abates when the bill is presented. ( Source 13) If invited to a pub or bar for a drink, it is very important to make sure you pay your ‘shout' – that means that everybody is expected to pay for a round of drinks.It is unadvisable to develop a reputation as someone who does not pay for his or her fair share of the drinks! Tipping is not always necessary but is usually expected at the better restaurants. Tips are usually for about 10% of the total bil l. (Source 13 : Worldliness culture website- Entertaining in Australia. HTML ) Appendix Source: World Business Culture -Australia/ Tips to live and to do business in Australia . Although Australia is relatively geographically remote and has a small domestic market, it is economically successful and its citizens have a comparatively high standard of living. . Due to its small domestic market, Australia needs to trade actively on the international market place and Australians know this – they are open to new ideas from overseas. 3. Australians prize their egalitarian approach to life- people should not try to make out that they are better than others. 4. This egalitarian world view is mirrored in many aspects of Australian business culture from corporate truckers to management and communication style. 5. On the whole, Australian hierarchical approach tends to sit uneasily in egalitarian Australia. 6.Managers try to develop a ‘mate' relationship with their colleagues and w ould be viewed negatively if they tried to seem aloof from subordinates. 7. Everybody expects to have an input into the decision-making process even if, in the final analysis, the boss still makes the decision. If the boss makes the decision with no prior consultation, it unlikely that people will be very keen to ensure implementation. 8. Decision-making meetings can e quite animated and it is expected that people will say exactly what they think without necessarily having to defer automatically to the boss' viewpoint. . Although Australians will say that they value punctuality as a professional necessity, do not be surprised if people appear five to ten minutes late for a meeting. 10.

Essay on “Rape, Racism, and the Law” Essay

Jennifer Wriggins analyzes the significance how race, ethnicity, and class influence a woman’s vulnerability to rape, the meaning and impact of the rape, and the response of family, of community, and of social institutions. Her article, â€Å"Rape, Racism, and the Law,† specifically focuses on the history of rape in the United States between the rapes of White women by Black men. As a feminist, she specifically focuses on two very damaging consequences of this selective blindness: the denials that Black women are raped; and all women are subject to pervasive and harmful sexual coercion of all kinds. Thorough this powerful essay, she examine the legal system’s treatment of rape and how racism plays a major part in denying the rights of African Americans, as well as, deny the veracity of women’s sexual subordination by creating a social meaning of rape which implies that the only type of sexual abuse is â€Å"illegal rape† and the only form of illegal rape is Black offender/White victim. I was exasperated after reading this article. This article highly irritated and annoyed me because of the interconnectedness of rape and racism. As a woman, it is hard not to get heated about this particular subject. Presently, there are now many struggles against rape. And, in acknowledging the struggles against rape one must also acknowledge the difference among women and the different ways that groups other than women are disempowered. In one of the many examples in this essay, racism and justice collide when in 1859 the Mississippi Supreme court dismissed the indictment of a male slave for the rape of a female slave less than 10 years old. â€Å"This indictment cannot be sustained, either at common law or under our statutes. It charges no offense known to either system. Slavery was unknown to the common law†¦ and hence its provisions are inapplicable†¦ There is no act which embraces either the attempted or actual commission of a rape by a slave on a female slave†¦ Master and slaves cannot be governed by the same system or laws; so different are their position, right and duties.† This ruling is disheartening in a few ways: Black men are held to lesser standards of restraint with Black women that are white men with White women; second, white men are held to lesser standards of restraint with black women that are Black men with white women. However, neither white nor black men were expected to show sexual restraint with black women. This is truly upsetting,  to me, because no man no matter what color should have the right to exercise rape or sexual coercion of any kind with any woman of any color without her consent. This reading is important to social work practice because it reflects and expansive and integrated approach to understanding rape, racism, and the law. By exploring the interconnectedness of rape and racism, I learned to analyze the assumptions implanted in and surrounding rape, racism, and social institutions. Finally, it develops understanding of the narrow focus of the black offender and the white rape victim, and the denial of the rape of black women, which engages within the cultural assumption of American society that is important to understand in the field of social work. This reading also teaches up to be receptive social work professionals able to work respectfully and competently with diverse population groups, with at the same time to understand and develop a sensitivity and respect for human rights. Through this reading, it is easy to see how stereotypes of racial and ethnic differences can have impact on a person’s life in regards to consequences, rewards, and punishments. It has not fit in because examining substantive justice arguably requires that human rights to life, well-being, and the commodities essential to life and well-being, be given priority whenever a societal decision is made. Societal conditions and institutional arrangements should be recognized as grounds for justification because they may impose limits and constraints on the choices available to an individual that are as unavoidable and compelling as those imposed by chance or by another human being. It is a scary thought that your skin color or sex could work against you in the legal system, but it does happen. For this reason, it is easy to understand why many women are not reporting these incidents. Reference: â€Å"Rape, Racism, and the Law† by Jennifer Wriggins
