Fire Protection system Essay Aqueous and non- aqueous agents employed in fire service means the use of such substance in the fire service work which helps in fast control and quick remedial measures against the broken out. Substantially non- aqueous, plastic, high magnesium oxide are used so that materials remain fluid over longtime providing for easy workability and require no addition of water prior to use. In the same manner aqueous substance in form of concentrated ammonium salt containing binder and viscosity agent are used by fire service provider to prevent wildfires. For decreasing the toxicity of the chemicals used in fire service organization, non- aqueous and aqueous fluid is used to provide easy control over heavy fire. Non–aqueous compositions are used containing an amount of volatile silicon which helps to maintain waterproof composition than previous conventional non- aqueous substance used by fire service provider. In recent time various aqueous mixtures containing tricalcium phosphate are used as it is experienced that when the mixture is used fire os frequently extinguished and even the fire did not catch up readily. Aqueous substances are treated as fire control agent as it has great adhesive power when applied to extinguish fire.

Afterschool program Essay

The combined efforts of the Washington, DC School system and the Woodson Foundation in the development of an Afterschool program to help increase and improve student outcomes. They have identified amply room for improvement. Three of the primary problems in the Washington, DC School systems are truancy, low student performance, and crime. They have also identified new staff (teachers) are quickly burnet out due to their initial enthusiasm in to want to help the students. This has caused a high turnover rate in new teachers, causing the school system to lose some of the best and brightest teachers to other school system in the area. The first stage in building a coalition is to select a representative from each of the organizations which will be involved in the program. This will give equal representation across the team. It has been identified that an Executive Development team should be established. This team will span across a multifunctional area to establish an operating plan for improving school performance. Participation from the Woodson Foundation and Washington, DC School system is the key element of a successful Executive Development team. However, representation from the National Coalition for Parental Involvement in education (NCPIE) should be considered, because they represent for the parent on the behalf of the PTA. The Coalition is in the forming stage of group development. A representative from each of the organizations will need to be assigned to the group. Then the group will need to figure out the groups purpose, structure, and the leadership of the group. In order for the Woodson Foundation to create this cohesive group, the stages of group development will need to be followed. The next step in the group development is storming. The representatives of the different organizations accept that the Executive Development team is needed, however each organization has their own principles they feel is important to the development. The leader is also established in this stage and there is a clear hierarchy of leadership. The third phase is Norming: In this stage, the Executive Development team has a solid group structure and a set of common expectations. Roles are established within this cohesive group.  The fourth stage is Performing: The structure of the Executive Development team is functional and all members accept it. The team is performing the tasks at hand and successfully completing them. The fifth stage is Adjourning. Even though the team is adjourning, they will collect the detailed analysis and put together a presentation of the Operational plan for improving the student’s performance in the After School program. Their findings will give clear direction of how to get the ASP going. One of the primary problems the Woodson Foundation is facing is what organization will lead the Executive Development team. In order for the leaders to lead this primary team, strong leadership and management is needed for top effectiveness. Today’s leaders should challenge themselves to identify status quo, create visions for the future, and inspire organizational members to want to achieve organizational goals and visions. The representatives from each organization of the Executive Development team, has their own vision as to why their organization should take the lead in building the team. The secondary problem the Woodson Foundation is to identify goals and objectives. The Woodson Foundation primary objective is outsider involvement to get a bigger and clearer picture of the program. NCPIE primary objective is having parent imput. They feel the Woodson Foundation can come in and do all they want, however if the parents do not participate the program will not work. Washington, DC School system primary objective is to let the professionals get the job done. The administrators feel they have the background, education, and expertise to spear head the program. These various backgrounds will enable the Executive Development team members, to have an understanding of the needs of the children participating in the ASP. One solution to the problem is building trust between coalition members and parents. The leadership will need to create an environment of trust that is conducive to all. Trust facilitates information sharing, encourages taking risks. However, trust builds a more effect team and enhances productivity (Robbins, pg 315). My second solution would be to identify and define clear responsibilities within the group. Each individual must be responsible and successfully complete research, presentations, and analysis for their areas of focus. This can clearly be accomplished by soliciting input from other team members (Robbins, pg 316). Each member of the group should have some type of training in managing diversity, conflict resolution, team building, and team cohesiveness. All members should have a clear understanding of their roles within the group and promote a climate of trust. Having a clear understanding of the leadership and its structure would better serve the Executive Development team’s primary function. Work Cited Robbins, Judge, Stephen P., Timothy A.

The novel titled, To Kill A Mockingbird, by Harper Lee is a story set in the small town of Maycomb, Alabama, during the depression in the 1930s. The story is told by a little six-year-old girl, Jean Louise Finch nicknamed Scout. She is a rebellious girl who has tomboy tendencies. Don’t waste time! Our writers will create an original "Indirect and Direct Characterization on To Kill A Mockingbird" essay for you Create order Scout lives with her elder brother Jem, and her father, Atticus, who is widowed. The book follows the family for three years where it discusses the arrest and eventual trial of a young black man, Tom Robinson, who is accused of raping a white woman. It also mentions how Scout and Jem befriend a boy named Dill who becomes fascinated with the spooky house on their street called the Radley Place. The house is owned by Mr. Nathan Radley, whose son Arthur (Boo), has lived there for years without venturing outside. To Kill A Mockingbird depicts discrimination against race and gender by showing examples of each of these in the everyday lives of the Finches and reveals why the novel is still relevant today. In To Kill A Mockingbird, Harper Lee illustrates discrimination against race by displaying many examples throughout the book, in the lives of the Finch family. One example of this is when Scout is at Finchs Landing for Christmas. During her visit one of her cousins named Francis approaches her and says, I guess it aint your fault if Uncle Atticus is a nigger-lover besides, but Im here to tell you it certainly does mortify the rest of the family (Lee 83). This is one instance of race discrimination because it shows how people are now hating on Atticus for defending black man. So, this goes to show that even Atticus own family is talking bad about him just because his client is colored which is extremely racist. Another example of this is when after Tom Robinson was named guilty and Atticus had to explain to Jem how in the world that could be possible and said, In our courts, when its a white mans word against a black mans, the white man always wins (Lee 220). This shows race discrimin ation because even the courts back then would favor white men over people who were colored. This was not okay because if its a matter of life or death people shouldnt have to die just because of the color of their skin. Finally, race discrimination is one of many types of discrimination that occurred in the Finches lives. In the book, Harper Lee reveals many instances of gender discrimination and how it affects the everyday lives of a specific family during the 1930s. When Dill and Jem wanted to look through the shutter of the Radley place Scout began to protest this idea and Jem said, Scout, Im tellin you for the last time, shut your trap or go home I declare to the Lord youre gettin more like a girl every day! (Lee 51). Here, through gender discrimination Jem uses it to get his way to insult Scout about her acting like a girl. Whenever she does something he does not like he gets away with bringing up the whole girl stereotype argument by calling her a girl. I doubt if wed ever get a complete case triedthe ladiesd be interrupting to ask questions (Lee 220). This is another example on how the author demonstrates gender discrimination in To Kill A Mockingbird because the polite fiction of the South is that women are delicate and need to be protected. Maybe the men are really just afraid that women woul d use power in a way that men wouldnt like. Thus, Harper Lee shows multiple examples on race and gender discrimination through the life of Scout. The novel also reveals effects of race and gender discrimination today by describing examples that are still relevant. In an article titled, Racism and its effects on society on be-utd.org it talks about how still to this date there are Families of a certain color or racial group living in poverty and poor conditions, unable to rise out of their disadvantaged state through the prejudice of employers which keeps them in low-paid positions. (be-utd.org 2018). This connects with the book because during the book they talk about the place where the colored folk live and how they live in poverty and have very little money. This important because it demonstrates how there are still some forms of racial discrimination happening in our world today. In another article titled, Gender discrimination comes in many forms for todays working women on pewresearch.org they talk about how, one-in-four working women (25%) say they have earned less than a man who wa doing the same job (pewresearch.org 20 18). Although, in the 1930s it was not very popular for women to work at all, still today women are having trouble being paid the same as a man. This proves that there is still such thing as gender discrimination in our world today. In conclusion, To Kill A Mockingbird depicts discrimination against race and gender. It does this by showing examples of each of these in the everyday lives of the Finches and reveals why the novel is still relevant today. The novel has many examples of race and gender discrimination however we need to be aware that this still continues today. The discrimination may not be as bad as the 1930s but it is still important and needs to me diminished. People should not have to feel less important or valued because of their race or gender. Sooner or later we must realize that we must develop a tolerance or undertsaninf for those who are different fromourselces. We must raise anew generation of tolerant indivisulas who embrace diversity and value all members of society equally.
