Aristotles opinions on Democracy essays

Aristotle's opinions on Democracy essays Aristotle, in pondering the study of the state, first decides to break down the state into its component parts: the family unit. The family is the association established by nature for the supply of mans everyday wants (1253a, 12). Uniting several families aims at more than just the daily needs of one family and this creates a village. Several villages when combined equal a state. The family unit is a patriarchal unit in which the man of the house is the natural leader. These earlier forms of society are natural and therefore the state is natural; it is the end of them and a nature is somethings end (13). The household is a patriarchal environment where the man is the sovereign, ruling over the women, children, and slaves. Aristotle comments For that some should rule and others be ruled is a thing not only necessary, but expedient; from the hour of their birth some are marked out for subjection and others for rule. This antidemocratic sentiment would lead people to believe that Aristotle supports monarchal or oligarchic versus democratic ideals. He continues to use the family unit as an analogy for society. Within each family unit is the master male figure that rules over the wife, both rule over the children and all rule over the slaves. He theorizes that the Father has a royal rule over the slaves and a royal rule over the children. He then says the man rules the woman constitutionally (an almost democratic thought) and with some exceptions, the male is naturally fitter for command then the female. He claims the rule works like this: the nature of citizens is equal, but whe n one rules over another a difference is created in the forms of names and titles of respect (1259b, 5). Aristotles position on the equality of women and men is confusing; he goes back and forth saying the woman is weaker and less fit for rule but then comparing their relationship to that of equa...

Resume and job search trends that will dominate in 2018

Resume and job search trends that will dominate in 2018 In 2012, The Ladders published the results of a study that shocked job hunters: on an average, recruiters spend only 6 seconds reviewing a candidate’s resume. From there on, job applicants started trying to make their resumes clearer, cleaner, and shorter. They started paying more attention to the format, aiming to make the most important details easily visible. Those trends persist but are constantly being upgraded. What can we expect in 2018? What resume and job search trends should we follow?We’ll give you a list of trends that will dominate the job search market in 2018, supported by experts’ opinions.Professionally Prepared Resumes  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In 2013, CareerBuilder surveyed thousands of hiring managers, human resource professionals, and workers across industries. 58% of the employers pointed out typos as the most common problem they saw in resumes. 36% of them said they were seeing resumes that were too generi c, and 32% of them identified â€Å"copying a large amount of wording from the job posting† as a problem.If you want to stand out, the resume has to be perfect.We contacted John Laurens, a   human resources manager from Resumes Planet. â€Å"Job applicants see typos the smallest problem. You can easily get rid of most of them if you use Grammarly or similar software. However, software won’t bring your resume to perfection. There are grammar and spelling mistakes that you can’t notice yourself,† – he says.Laurens is sure that professionally prepared resumes will be one of the biggest trends among job seekers in 2018: â€Å"When you’re not proficient in resume writing, you can rest assured that you’ll make a mistake. You’ll either write a generic resume or you’ll get into too many details. A professional writer is aware of the standards of different industries. Job applicants are finally realizing they can improve their chances of getting the interview call if they hire a writer to complete or improve their resume.†Personality Will Play an Even Greater RoleIn August 2017, the unemployment rate in the U.S. was similar to the trend we’ve been experiencing for years – 4.4%. This means that 7.1 million people are unemployed. What does this mean for a job hunter? Huge competition. What does it mean for a recruiter? Plenty of resumes to review.The hiring manager will look for the candidates with the core skills needed for the specific job. The personality traits, however, are just as important. Employers want people who would fit into their office culture. Your resume can convey your personality up to a certain point, but you’ll have to do something more: follow up.Laura Handrick, human resources staff writer at Fit Small Business, agrees. â€Å"Job search continues to be personal. People don’t hire form paper, they hire people they trust will do a great job in the rol e.† – she says.â€Å"So after you apply, follow up in any (and maybe every) way you can – contact the recruiter on Facebook, or look for someone you know who works there in your LinkedIn account. My last resume sent via Indeed was never found by the staffing agency. It was only when I sent an InMail to the recruitment firm owner that I was contacted, asked to resend it via email, contacted by the recruiter, scheduled for interviews, and hired. If you fail to follow up with a phone, email, postcard or other form of human contact, you may as well have placed your resume directly into the shredder.†Social Media Will Get More ImportantA recent survey showed that 70% of employers are screening candidates via social media before hiring them. 54% have decided not to hire a candidate after screening their social media profiles, and 57% are less likely to consider someone for an interview if they can’t find them online.That’s how serious social media reputation is in the hiring process. The trend is going to get even bigger during 2018. Scott Wesper, hiring manager for Arch Resources Group, agrees:â€Å"As 2018 draws closer, social media will play an even bigger role in job search trends. When you compare the number of users overall, Facebook wins in a landslide victory over LinkedIn. Facebook has 1.86 billion users, while competitor LinkedIn has only 433 million members. Most Facebook profiles are filled with important demographic information like age, past job titles, employer information, educational background, and even interests. This will be key for employers as they target their job ads in order to reach the candidates with the proper credentials.Digital Resumes and PortfoliosIn 2015, the Pew Research center conducted a survey called Searching for Work in the Digital Era. The results showed that 54% of U.S. adults were looking for job information online, and 45% had applied for a job online.The Internet is the most impor tant resource during the job hunting process. You don’t use it just to search for a job. It’s also a medium that presents you as an ideal candidate. That’s why you’ll have to work on your digital resume and portfolio, since more employers will be interested in that factor in 2018.Alec Sears, human resources manager from Frontier Communications, says: â€Å"In 2018 you will see a shift towards digital resumes and portfolios. The format of the resume itself won’t change much; it is simple and succinct and there’s a reason that it’s stood the test of time. But sites like Indeed and Glassdoor make it easier than ever to take that resume and send it out to dozens of potential employers at once. Wise job-seekers will utilize personal websites, online portfolios and even LinkedIn connections to stand out.†Did you hear that? Wise job seekers will have personal websites. They will also have an impressive online reputation that’s visible through social media. They will be getting professionally-written resumes and they will make an effort to show their personality after submitting them. As a wise job hunter, those are the trends you should be aware of.About the authorMicheal Gilmore is an entrepreneur and HR expert from Dallas, TX.   His mission is helping people achieve perfection in anything they do.   His life is fully dedicated to the people.

The Crucible Essay Example | Topics and Well Written Essays - 1000 words - 1

The Crucible - Essay Example Mostly, the little lies are used to spice up the story or achieve a certain effect among the audience. There are various reasons for which people do lie. In many cases the lies are propagated to save certain situations or protect certain interests the individual lying may have. In some instances, people have lied even under oath. This paper seeks to delve into the reasons as to why people lie, even under an oath In the 1953 play by Arthur Miller, The Crucible, he depicts the Salem Witch Trials. The trials are carried out in such a way that the villagers’ testimonies determine the fate of the accused. Several innocent people meet their deaths courtesy of the testimonies. On the other hand, some guilty characters escape death as the villagers’ testimonies save them. Clearly, an accused person’s life balances on what the mob has to say of him or her. For those who get saved yet are guilty, lies do it for them. The villagers simply have to lie on the truth about them for their lives to be saved. Some innocent characters are however not as lucky. The villagers’ false affirmation to their participation in witchcraft leads them to their death. The villagers actually lie big time depending on whom they want to save or crucify. The accused also resort to lying in order to save themselves. Extreme behaviors occur during this time when life or death is made by the differenc e between treachery and truthfulness. Apparently, fear appears to be the reason behind the lying. The characters Abigail William, Mary Warren and John Proctor are the most deceiving. Abigail goes to great lengths to deceive Salem’s townspeople for her selfish gains. Questioned about dancing in company of the other girls in the woods, she puts the blame on Tituba. She quips, â€Å"She made me do it! She made Betty do it!† (187). Apparently, she is willing to sacrifice Tituba’s life so that she can escape punishment. On the other hand, while Tituba

European Aviation Safety Agency Essay Example | Topics and Well Written Essays - 1500 words

European Aviation Safety Agency - Essay Example It is tasked with promoting the highest possible safety standards, as well as environmental protection in the aviation industry, both in the EU member states, and the world in general. EASA assumed full responsibility in 2008 and took over the functions of JAA (Joint Aviation Authorities). The agency is mandated to undertake the following activities: There are several differences between EASA and JAA. JAA had its head office in Hoofddorp, Amsterdam, while EASA, has its headquarters in Cologne, Germany. In addition, EASA has the legislative mandate within the European Union (EU) by enacting regulations through the European Commission, Council of the European Union and European Parliament. On the other hand, JAA operated products without direct force of law. This means that JAA was not recognized as a legal body; but rather, it was a â€Å"mere cooperation of JAA member countries in the field of civil aviation† (Cristiansen, 2009, p. 61). Moreover, some countries under JAA such as Turkey operated outside the EU, whereas, by definition, EASA is an agency that operates under the EU and other countries adopt its rules and regulations without being forced. The fundamental basis for the formulation of EASA is to ensure mandatory standardization. The agency is the one that gives certification. It also â€Å"acts as the authority in the field of airworthiness and continuing airworthiness† (Cristiansen, 2009, p. 62). EASA has authority over new types of certificates and other designs that pertain to airworthiness approvals for aircrafts, engine, propellers and components. The agency works hand in hand with the National Aviation Authorities (NAAs) of the European Union members. However, EASA has virtually taken over most functions from NAAs so as to ensure uniformity of standards across the EU. EASA also has an important part in helping the European Commission negotiate and

Learning Disabilities Contributor Essay Example for Free

Learning Disabilities Contributor Essay This paper will discuss students with nonverbal learning disabilities syndrome. Nonverbal learning disabilities NLD will be addressed as to what is NLD and what students are usually have. This will be an overview of how to not only identify students with NLD but how to assists students with NLB. This paper will go over important strategies and inventions that will help students with NLD. NLD has been around for fifteen years. NLD is a disorder that is not mentioned or heard a lot in education. This disorder is mentioned in medical and psychological literature. In this paper the author will discuss the issues of NLD and why educators should ignore the characterizes and signs of this disorder. Research will show that this disorder could have come from variety of neurological and development conditions. This could have happened either from a brain injury, untreated disease, or Asperger syndrome. There are strategies to help students that suffer from NLD. NLD is a poorly understood disorder it is a disorder that can be not only be understood but can be helped. With the strategies and inventions that we will be going over in this paper will help students with NLD have a fighting chance. What is nonverbal learning disabilities? Students who have NLD usually show signs in strong verbal than perceptual cognitive skills, weak pyschomotor, deficiency in math, difficulty in complex tasks and social deficits. Students with NLD do better when information is given to them verbally than shown to them visually. This student can process the information better when the information is being given to them orally. When this type of student is receiving the information visually the student is unable to receive it cognitively. Where as the information is being given to them verbally then the information will process properly because this student has a strong verbal process. Weak pyschomotor is another trait that students with NLD have(Telzrow Bonar, 2002). These students usually show signs in having a hard time with playing certain games such as skipping rope or riding a bike. NLD students have a hard time with life skill tasks such as dressing themselves and other self care skills. Deficiency in math is another area that students with NLD have a problem with. Students with NLD usually do well in reading and spelling but math is a huge hurdle they have to accomplish. The symbols and procedures in math are a hard concept for students who have NLD to understand. Difficulty in complex tasks are another problem for students with NLD. These students have a hard time in social setting because of this problem. They usually demonstrate that they have a hard time with problem solving. The problem solving skills also effects poor judgment skills. These students are very impulsive with their behavior and do not have a sense of personal space. A student with NLD has a hard time verbally communicating what the problem is and how to explain what they really meant or need(Telzrow Bonar, 2002).. Students with NLD can get the help they need. If a student with NLD has problems with psychomotor there are things in the classroom to help students with this problem. If the student has an issue finishing a writing task then you can give the student extra time to finish the writing task. If the student has a real issue with writing and the student is good a typing then you can let the student type instead of writing. Another way to help students with psychomotor is to give a them a multiple test instead then an essay test. Teachers need to make sure that lectures dont have that many note taking tasks. These are a few strategies to help and relieve stress for students with psychomotor problems(Telzrow Bonar, 2002).. It is important for these students to focus on learning and not be stressed out about tasks that they can not complete. Teachers can use these strategies for students that have deficiency in math. Students that have a deficiency in math can use manipulatives to help these students. One way example of a manipulative that a student can use is a calculator. Using a calculator can help students do math problems and learn how to to add, subtract or multiply. Having students memorizing additions problems, subtracting problems and multiplication problems. Direct instruction on math on step by step with verbal instruction. Showing students one on one instruction on math concepts and checking strategies to help students get better and confidence in math(Telzrow Bonar, 2002). Students with NLD have issues with problem solving skills. These students need to focus on various social situations. One good way for these students to learn problem solving skills is to role play. Role play is a good way to show students examples of problems that arise in certain situations. By role playing students are able to learn how to take action on their own and to also build confidence(Telzrow Bonar, 2002). The more practice in role play the more the student is to learn how to do the problem solving on their own. Another way to learn problem solving skills is to set rules for these student to follow. Setting rules will help students learn what is appropriate and what is not appropriate. This will help set guidelines for student to follow and learn in the process. Social skills are another issue that students with NLD. Role playing is very important for these students to learn from. These students need direct instruction on how to make appropriate eye contact, how to greet others and to learn other appropriate social skills. It is also important for these students to learn how to make and keep friends. It is also important for these students to learn how to act appropriately act in a work setting. If these students want to succeed in life learning how to act in a working environment is key. Learning how to behave appropriately in a work setting will help them keep a job and live a successful independent life. The last issue that a student with NLD usually deals with is psychosocial adjustment problems. These students need to learn how to control impulsive behavior and inattention. Students that have a hard time with dealing with this issues and need to learn how to self-monitor themselves. NLD students need to learn how to slow down and be aware of what they are doing instead of just reacting(Telzrow Bonar, 2002). Another problem these students have is not thinking for speaking. These students need to learn ways to think about what they want to say before just saying it. Students that display these issues need to learn relaxation skills to help reduce anxiety.  These students need to learn how to ask for breaks or help when they are feeling stressed out. The author has gone over what NLD symptoms and characteristics of what to look for in students that may be suffering fro this problem. The author has also gone over strategies to help students that have NLD. The strategies and methods that were mentioned are tools to not only help the students but to help the students learn the proper tools to help themselves outside the classroom. With any student that is having a hard time in school it is the teachers job to make sure that students needs are being met. Students that have NLD need strategies and methods to help them so they can focus less on their problems and more on learning(Telzrow Bonar, 2002). By using strategies on students with NLD this will help these students learn the tools that they need to deal with the world around them. References Telzrow, C. F., Bonar, A. M. (2002).

Social System in Gabriel Marquez’s Chronicle of a Death Foretold and Al

Social System in Gabriel Marquez’s Chronicle of a Death Foretold and Albert Camus’s The Stranger â€Å"Like father, like son† the old saying goes. And naturally this is so, for if the parent lacks morals, logically the child will too. Just as parents shape their children, authority figures shape their societies. Authority figures have great impact on the common people, for if they act in dishonest or fraudulent manners, the society considers it acceptable to do the same. Such reflections between authority figures and society are seen throughout Gabriel Marquez’s Chronicle of a Death Foretold and Albert Camus’s The Stranger. With societies constantly looking to authority figures for guidance, Marquez and Camus satirically depict folly in the actions of the leaders in order to criticize the social system and reveal the accepted selfishness that is reflected by the people. In order to completely understand the manner in which authority figures actions become reflected on society, a reader must observe the social system through the eyes of the narrator. Marquez begins Chronicle of A Death Foretold by establishing the town to appear very religious. The novel commences with the townspeople thoroughly preparing for the yearly arrival of the bishop. The whole town arranges for his arrival, bringing him many gifts and animals. Although Marquez establishes the city as consumed in religious dedication, a reader must analyze the thoughts of the townspeople in order to truly understand the society. The individuals of the community make elaborate preparations, not to show their spiritual devotion, but to benefit their personal selves. Each person concerns themselves with receiving a blessing from the bishop. The people seem to be... ...ngs in order to expunge their sins, The Stranger also presents faith as a means to obliterate sins. In both systems, people rely on religion in hypocritical manners. Instead of desiring a spiritual peace, the people have been taught by authority figures, like the magistrate, to use religion in self-interest. Overall, Marquez and Camus break the spiritual, rational, and impartial facades of the authority figures by exposing the idea that; since the leaders of the society were unable to provide a moral structure for their citizens, an accepted form of selfishness unfolded within the societies. The social systems in both novels act as the shadow of the bishop and the magistrate. Like a shadow, the societies follow in the leaders footsteps, for the society lives as a dark reflection of the authority figures who promote selfishness and false public images.

Beauty: Wish and Carla

This funny witty story â€Å"Beauty† by Jane Martin is about two girls who argue about the facets each one has. Carla is the definition of beauty, and Bethany who is the opposite carries something Carla wishes she had: brains, personality, and a college degree. The play relies mostly on wit and wordplay with only two characters and a genie lamp. Both Carla and Bethany envy one another; wishing they had each other’s looks or persona.When Bethany has the power to change what she has and get what she has always wanted; the writer uses Carla to show that Bethany will be disappointed with the set of dialogue they use back and forth. Carla is clearly not happy with herself and her insecurities; meanwhile so is Bethany, discovering that everyone has different problems no matter what they look like. Everyone is envious of someone for something not realizing they have problems they won’t understand.Because â€Å"Beauty† is a play, Martin introduces the characters t hrough dialogue. The first character, Carla, is first seen talking on the phone with a random suitor that she met at a bar and she cannot seem to remember. This is evidence that Carla has some type of beauty that attracts male attention, even without any actual interaction. Later in the play, Carla references the fact that she has a modeling meeting with Ralph Lauren, reiterating the fact that she is physically beautiful.The second character, Bethany, is Carla’s friend, and obviously a good friend because she does not mind interrupting Carla on the phone regardless of how many times Carla asks her to be quiet. Bethany has a demanding job as a public accountant, and decides to take a break to go to the beach. While there, she finds a lamp with a magic genie inside. The magic genie grants Bethany three wishes, three chances to have something she would not normally get in her life. Martin uses the genie to unmask Bethany’s hidden desires and discontent in her life.

How to Pass a Test

How to Pass a Test We sometimes spend so much time using flashcards and memorizing terms that we dont get around to really  gaining a deep understanding of the material were supposed to be  learning!  The fact is, many students dont realize that there is a difference between memorizing and learning.Memorizing terms and definitions may help you prepare for some types of tests, but as you advance into higher grades, youll find that teachers (and professors) expect a lot more from you on test day. You may go from providing definitions to words in middle school, for example, to more advanced types of responses like long answer essays when you reach high school and college. For those more complex question and answer types, youll need to be able to put your new terms and phrases in context. There is a way to know if youre really ready for any test question the teacher can throw at you. This strategy is designed to help you take the knowledge youve gained about a subject and explain it in context And you can learn this strategy in three steps! First, develop a list of all the terms (new words) and concepts contained in your material.  Find a way to randomly pick two of these terms. (No picking and choosing!) For example, you could use index cards or scraps of paper to write the term on one side and then place them face-down. Then select two different cards. The strategy works best if you actually manage to pick two (seemingly) unrelated words.Now that you have two unrelated terms or concepts, your challenge is to write a paragraph (or several) to show the connection between the two. It may seem impossible at first, but it is not!Remember that any two terms from the same class will be related. You just have to create a path from one to the other to show how the topics are related. And you cant possibly do this unless you really know the material. Tips for Passing Your Test Repeat the process of selecting random terms until youve done several different combinations of terms.Every time you write your paragraph(s) to connect the terms, use as many other terms as you can. You will begin to build a web of knowledge and begin to understand how everything relates to everything else in your notes.Once youve studied this way, follow up with a friend a day or two later. Use a study partner and write up practice essay questions and exchange them. Make sure that each answer contains at least two of the terms youve practiced.

Bacterial Reproduction and Binary Fission

Bacterial Reproduction and Binary Fission Bacteria are prokaryotic organisms that reproduce asexually. Bacterial reproduction most commonly occurs by a kind of cell division called binary fission. Binary fission involves the division of a single cell, which results in the formation of two cells that are genetically identical. In order to grasp the process of binary fission, it is helpful to understand bacterial cell structure. Bacterial Cell Structure Bacteria have varying cell shapes. The most common bacteria cell shapes are spherical, rod-shaped, and spiral. Bacterial cells typically contain the following structures: a cell wall, cell membrane, cytoplasm, ribosomes, plasmids, flagella, and a nucleoid region. Cell Wall: An outer covering of the cell that protects the bacterial cell and gives it shape.Cytoplasm: A gel-like substance composed mainly of water that also contains enzymes, salts, cell components, and various organic molecules.Cell Membrane or Plasma Membrane: Surrounds the cells cytoplasm and regulates the flow of substances in and out of the cell.Flagella: Long, whip-like protrusion that aids in cellular locomotion.Ribosomes: Cell structures responsible for protein production.Plasmids: Gene carrying, circular DNA structures that are not involved in reproduction.Nucleoid Region: Area of the cytoplasm that contains the single bacterial DNA molecule. Binary Fission Most bacteria, including Salmonella and E.coli, reproduce by binary fission. During this type of asexual reproduction, the single DNA molecule replicates and both copies attach, at different points,  to the cell membrane.  As the cell begins to grow and elongate, the distance between the two DNA molecules increases. Once the bacterium just about doubles its original size, the cell membrane begins to pinch inward at  the center. Finally, a  cell wall  forms  which separates the two  DNA molecules and divides the original cell into two identical daughter cells. There are a number of benefits associated with reproduction  through binary fission. A single bacterium is able to reproduce in high numbers at a rapid rate. Under optimum conditions, some bacteria can double their population numbers in a matter of minutes or hours. Another benefit is that no time is wasted searching for a mate since reproduction is asexual. In addition, the daughter cells resulting from binary fission are identical to the original cell. This means that they are well suited for life in their environment. Bacterial Recombination Binary fission is an effective way for bacteria to reproduce, however, it is not without problems. Since the cells produced through this type of reproduction are identical, they are all susceptible to the same types of  threats, such as environmental changes and  antibiotics. These hazards could destroy  an entire colony. In order to avoid such perils, bacteria can become more genetically  varied  through recombination. Recombination involves the transfer of genes between cells.  Bacterial recombination is accomplished through conjugation, transformation, or transduction. Conjugation Some bacteria are capable of transferring pieces of their genes to other bacteria that they contact. During conjugation, one bacterium connects itself to another through a protein tube structure called a pilus. Genes are transferred from one bacterium to the other through this tube. Transformation Some bacteria are capable of taking up DNA from their environment. These DNA remnants most commonly come from dead bacterial cells. During transformation, the bacterium binds the DNA and transports it across the bacterial cell membrane. The new DNA is then incorporated into the bacterial cells DNA. Transduction Transduction is a type of recombination that involves the exchange  of bacterial DNA through bacteriophages. Bacteriophages are viruses that infect bacteria. There are two types of transduction: generalized and specialized transduction. Once a bacteriophage attaches to a bacterium, it inserts its genome into the bacterium. The viral genome, enzymes, and viral components are then replicated and assembled within the host bacterium. Once formed, the new bacteriophages lyse or split open the bacterium, releasing the replicated viruses.  During the assembling process, however, some of the hosts bacterial DNA may become encased in the viral capsid instead of the viral genome. When this bacteriophage infects another bacterium, it injects the DNA fragment from the previously infected bacterium. This DNA fragment then becomes inserted into the DNA of the new bacterium. This type of transduction is called generalized transduction. In specialized transduction, fragments of the host bacteriums DNA become incorporated into the viral genomes of the new bacteriophages. The DNA fragments can then be transferred to any new bacteria that these bacteriophages infect.
