A sailor is also known as a mariner or a seaman. Sailors work on passenger ships, freighters, and tanker ships. A sailor navigates sea-going vessels and assists with the maintenance, operation, and service of these vessels. The term sailor was derived from the fact that all water-borne vessels were once powered by sails. Now the term encompasses all types of vessels, no matter how they are powered. Today, sailors may work for the military or private companies in all aspects of marine employment.

Mathematicians use high-level mathematics and technology to develop new mathematical principles, understand relationships between existing principles, and solve real-world problems.

A person who practices materials science is one who studies and analyzes the chemical properties and structure of different man-made and natural materials. Glass, rubber, ceramic, alloys, polymers, and metals are all studied and investigated to learn or gain new knowledge. They then take this knowledge and devise ways to strengthen existing materials, combine particular materials, or create brand new materials with certain properties and characteristics for use in different applications and products. By experimenting with various materials and chemicals, these scientists can determine how new materials can best serve and improve humanity. Materials science professionals have created many of the items that people use today such as shoes, soap, canisters, containers, makeup, packaging materials, and so on. The main goal of someone practicing materials science is to study and understand old materials in order to create new material with improved characteristics.

Credit analysts, also known as financial analysts in the business world, play a very important role in the health of the economy. Credit makes the entire modern economy function from day to day. Without the objective recommendations of financial analysts, banks and insurers would not be able to extend lines of credit to businesses or individuals seeking loans for homes, cars and occasionally employee payrolls as well. Assessing many different risk factors encompasses collecting a large amount of financial information. Credit analysts compile these financial records and make wise recommendations on whether or not to extend credit. Objective financial analysis is the hallmark quality of successful credit analysts, particularly analysts employed at large global financial institutions. Credit analysts combine the intricacies of financial statements with current financial market conditions. Given the instability in the global economy as a whole, opportunities for employment as a credit analyst are in very high demand as companies large and small look for ways to remain profitable. Providing companies and investors with the financial analysis necessary to make shrewd business choices gives credit analysts ample opportunity to earn very lucrative performance-based bonuses as a result.

Health educators teach people about behaviours that promote wellness. They develop programs and materials to encourage people to make healthy decisions. Health educators work in a variety of settings, including hospitals, non-profit organizations, government, doctors’ offices, and private business, and colleges. They generally work full time.

Pipelayers lave played a large role in creating the infrastructure of modern civilization. Modern plumbing and much of the world's energy all depend on pipes that these workers have laid. Pipelayers are often confused with pipefitters, and while they are in the same class of work, they are not technically the same job. Pipelayers are the tradesmen who perform the initial groundwork for construction by laying down pipes that provide sewage disposal, drainage or water. Apart from construction, some of the other industries in which a pipelayer may work include natural gas distribution, where pipelines are used to carry the gas to be used as fuel, and the building of utility systems. Like others in the various construction trades, a pipelayer will have to spend several years working as an apprentice under a more experienced journeyman pipelayer before being able to work on their own or train apprentice pipelayers.

Models pose for artists, photographers, or customers to help advertise a variety of products, including clothing, cosmetics, food, and appliances.

Medical and health services managers, also called healthcare executives or healthcare administrators, plan, direct, and coordinate medical and health services. They might manage an entire facility, specialize in managing a specific clinical area or department, or manage a medical practice for a group of physicians. Most work in office settings in healthcare facilities, including hospitals, nursing homes, and group medical practices.

Workers in water transportation occupations operate and maintain ships that take cargo and people over water. The are sometimes called merchant mariners. These ships travel to and from foreign ports across the ocean to domestic ports along the coasts, across the Great Lakes, and along the country’s many inland waterways. Work schedules and conditions vary by the type of ship. Most workers work long hours while they are on the ship.

Bill and account collectors, sometimes called collection agents, try to recover payment on overdue bills. They negotiate repayment plans with debtors and help them find solutions to make paying their overdue bills easier. Many bill and account collectors work in a call center for a third-party collection agency rather than the original creditor. Most work full time, and some have flexible schedules. Collectors must usually have a high school diploma and experience in a call center. A few months of on-the-job training is common.

Forest workers measure and improve the quality of forests. Under the supervision of foresters and conservation technicians, they help to develop, maintain, and protect forests.

A person passionate about the Internet and computers is ideally suited for a position in web development. A web developer is also known as a web content developer or a front-end developer. A front-end developer builds and maintains web sites for the World Wide Web or an intranet. An intranet is a system internal to a corporation, institution, or government. Some developers freelance their skills to various organizations. Others choose to outsource their skills to organizations by using their expertise to act as consultants or independent contractors.

Anyone who has ever signed a mobile-phone or other consumer contract, a lease or an employment agreement has probably seen in the contract's fine print a provision known as an "arbitration clause." This widely used legal covenant requires that in the case of a dispute between the parties, the arbitration process be used to resolve their differences. In these situations, both sides to the dispute rely on an arbitrator, also known as a "neutral," for an informed, unbiased resolution. Arbitration is an alternative to filing a lawsuit, and the neutral plays a critical role in settling disagreements. Instead of appearing before a judge in a courtroom, the opposing parties present their case to the arbitrator, whose decision is often final and, only in certain circumstances, cannot be appealed. Arbitration is used instead of courtroom proceedings because it is often quicker, less time consuming and not as costly. In addition to consumer disputes, commercial and real-estate controversies are often handled through the arbitration process. Arbitration is also frequently used to resolve family conflicts such as divorces because it can be cost effective and offers a degree of privacy, since it is not a part of the public record. Online dispute resolution (ODR) is a relatively new form of arbitration. By using computers and specially developed software, the parties can file an initial dispute, find and appoint a neutral, produce evidence and even participate in hearings online. ODR significantly extends the geographic boundaries in which a neutral can work.

A meat cutter is also known as a butcher. A meat cutter prepares large pieces of meat and slices and cuts them into smaller and more manageable pieces for use by consumers. They may work for a large meat processing company, a butcher shop, or a grocery store.

Aviation Inspectors, also known as aviation safety inspectors, have been keeping the world's air transportation system safe since the development of an American airway system in the early 1920s. Although it was originally created for the U.S. Air Mail Service, it was transferred to the Federal Aviation Administration, or FAA after the Federal Aviation Act was established in 1958. Aviation inspectors are responsible for the safety of everyone who boards an airplane, as well as those remaining on the ground. Conducting preflight inspections to ensure the safety of an aircraft, these inspectors are critical in confirming that the craft is safe for flight. They have a mechanical aptitude and are able to diagnose and resolve complex problems. Often working for the FAA, they understand that following all safety guidelines is an important responsibility; therefore, an aviation inspector can mandate changes to maintenance schedules and suggest repairs as needed. Being superbly trained, they examine all the components that can affect an individual flight to ensure the safety of it's crew and passengers.

Agricultural workers maintain the quality of farms, crops, and livestock by operating machinery and doing physical labor under the supervision of agricultural managers. They typically work outdoors. Some work primarily with crops and vegetables. Others handle livestock. They generally receive on-the-job training.

An electrical engineer is someone who designs and develops new electrical equipment, solves problems and tests equipment. They work with all kinds of electronic devices, from the smallest pocket devices to large supercomputers. Electrical engineering deals with electricity, electro-magnetism and electronics. It also covers power, control systems, telecommunications and signal processing. They are usually concerned with large-scale electrical systems such as motor control and power transmission, as well as utilizing electricity to transmit energy. Electrical engineers may work on a diverse range of technologies, from the design of household appliances, lighting and wiring of buildings, telecommunication systems, electrical power stations and satellite communications. They may plan their designs using computer-aided software or they may also sketch ideas by hand. There are many sub-disciplines of electrical engineering.

A faller is a logging worker, part of an industry that harvests millions of trees each year around the world. Throughout history the profession was known as the lumberjack and the image of a burly man in chainsaw boots, checkered flannel shirt and suspenders forms part of legend and popular culture. Lumberjacks were heros in folklore and fairy tales, such as Paul Bunyan and Little Red Riding Hood, and there are many lumberjack songs in early American and traditional Irish and Scottish music. In the past the lumberjack did dangerous and primitive work, but had the reputation of being exceptionally strong, masculine, and able to confront any kind of danger. Without fallers we would have no raw materials to make wood products that are so important to our construction industry and our daily lives. Although the work is repetitious, falling trees by hand involves a high degree of specialized skill and concentration, and a commitment to make safety part of every work day. Logging has a reputation as being hazardous, but recent technological advancements have reduced many of the risks. In addition to chainsaws, feller-buncher operators, for example, use machines that are like backhoes to cut trees at the base and pile them up. Although the profession has traditionally been restricted to men, many women are now becoming fallers.

A political scientist is a person who studies government, political processes and political issues in a scientific way, often within the context of an academic institution. This field of study encompasses many things besides the formal institutions of government. Formal laws are indeed studied, but so are things like public opinion, parties and economics. As a science, the study of politics in an academy strives to be systematic, objective and impartial. Randomness and subjectivity are avoided, while personal biases and partisan views are kept out of the process. A political scientist can give opinions as well as conclusions, but they are always based on fact and supported by evidence and reasoning. The field is diverse and includes many different subfields. Some political scientists specialize in the study of a single country's unique institutions, such as in the study of American Government. Then there is the subfield of Comparative Politics, which compares different systems like democracies, republics, monarchies, etc. Political Economy is the subfield that deals with economic policy, such as fiscal, monetary and stabilization measures, as well as public regulation of industry. Foreign policy, military questions, national security, trade policy and international finance would generally fall under the category of International Relations. Finally, there are the two closely related subfields of Political Theory and Philosophy. These two areas would deal with more philosophical and analytical questions like justice and rights, and how these concepts would be applied to current institutions; for example, the ways in which political reform might lead to a more just or efficient arrangement of society.

Editors are critical readers that love words. They are the people who prepare the writing of others for publication. Editors are seen as gatekeepers between the writer and audience, and they have to take a dual-sided point-of-view in order to keep both parties happy. Authors know their stories inside and out and have had a strong relationship with their manuscript for years. Audiences, on the other hand, have no emotional attachment to books that they have not read yet and are quick to judge any novel that they pick up to read. The editor needs to edit a manuscript from both points-of-view. Changes that are to be made must feel like the author's authentic voice to keep him or her happy with the new and improved manuscript. The manuscript may also need changes that will keep the audience pulled in and interested for the length of the novel. One of an editor’s many challenges is to find a balance between the two.
