Professors instruct students in a wide variety of academic and vocational subjects beyond the high school level. They also conduct research and publish scholarly papers and books. They work in public and private colleges and universities, professional schools, junior or community colleges, and career and vocational schools. Outside of class time, their schedules are generally flexible. Educational requirements vary with the subject taught and the type of educational institution. Most commonly, professors must have a Ph.D. However, a master's degree may be enough for some postsecondary teachers at community colleges. In technical and trade schools, work experience may be important for getting a postsecondary teaching job.
Petroleum, or oil, has been utilized since prehistoric times to provide warmth and light, in warfare, and for medicinal purposes. It is an essential resource which is used daily in most parts of the world. A petroleum pump system operator oversees petroleum refining and processing. Both the manifold and the pumping system will be controlled, governing the circulation of liquid materials through a refinery.
Respiratory therapists care for patients who have trouble breathing; for example, from a chronic respiratory disease, such as asthma or emphysema. They also provide emergency care to patients suffering from heart attacks, stroke, drowning, or shock. Most respiratory therapists work in hospitals. Others may work in nursing care facilities or travel to patients’ homes.
Tile and marble setters apply hard tile, marble, and wood tiles to walls, floors, and other surfaces. Installing tile and marble is labour intensive, and workers spend much of their time bending, kneeling, and reaching. Although the occupation is not as dangerous as some other construction trades, workers still experience a high rate of injuries and illnesses.
The idea of working as a lifeguard may bring up a picture of hunky guys and gorgeous girls who are tanned, muscular and beautiful and who perform daring Baywatch-style rescues along the beach. In reality, of course, the job is quite different from how it is depicted on television. Lifeguards come in all sizes and shapes, and they work inside as often as on the beach. It is, however, an extremely important job because it involves keeping people safe. Lifeguards are expert swimmers who work at almost any location where people swim. They know how to save a person who is drowning or who has sustained an injury while swimming, and they can give artificial respiration if required. They keep a close eye on all the people under their care. The job of a lifeguard is one with a great deal of responsibility.
Hazardous materials (hazmat) removal workers identify and dispose of asbestos, radioactive and nuclear waste, arsenic, lead, and other hazardous materials. They also clean up materials that are flammable, corrosive, reactive, or toxic. Hazmat removal workers face different working conditions, depending on their area of expertise. Some must wear fully enclosed protective suits for several hours at a time. Completing projects often requires night and weekend work. Overtime also is common, especially for emergency or disaster response workers.
Molecular biology is a field of science that explores and studies the structures and functions of cells on a molecular level. Experts in molecular biology must be proficient in numerous subjects and sciences before they can effectively conduct research or academic activity in their field. It is presumed that all cell functions, which are incredibly complex and incompletely understood, take place on a molecular level. This means that the sophisticated interconnection and cooperation of biological molecules is what makes life possible, which is an intriguing subject that puzzles molecular biologists and motivates them to discover the secrets of cells. A molecular biologist is a highly intelligent individual that is preoccupied with exploring, understanding or teaching the concepts behind cellular structure and function on a molecular level. Cells are made of highly sophisticated structures called cellular organelles, which include the nucleus, the endoplasmic reticulum, lysosomes, the Golgi apparatus and many more. Each of these organelles performs a particular function. However, unlike parts in a car, the functions of each cellular component are not clear-cut, and there is a high degree of dependency and overlap between their functions. Experts in molecular biology dedicate their life to deciphering these complex functions and exploring the biological laws governing the operation of each cellular component. Moreover, cellular organelles are further composed of complex biological molecules such as the DNA, the RNA, proteins, lipids and carbohydrates, and many possible combinations among them. The task of a molecular biologist is to develop an understanding of how biological molecules come together to function as organelles, and ultimately as cells performing a particular function within the body.
An explosives worker is a highly trained professional who works with volatile substances such as industrial chemicals, weapons and explosive demolition materials. As the name implies, these individuals deal frequently with very dangerous substances and must have exceptional powers of concentration to keep themselves and those around them safe. The mining industry employs explosives workers to set dynamite charges and expose new mineral veins; law enforcement and military applications for an explosives worker may include defusing bombs and rigging land mines. Other explosives workers work in construction and demolition, where they must choose which explosives to use, and where to place them, so that a condemned building collapses safely and quickly.
A fraud analyst is someone who investigates forgery and theft within customers’ accounts and transactions on behalf of a bank or a financial institution. They track and monitor the bank’s transactions and activity that comes through the bank’s customers’ accounts. It is their job to identify and trace any suspicious or high-risk transactions, and determine if there is improper activity involved and if there is risk to the bank or its customers. They must conduct and lead investigations into any potential fraudulent activity up to their natural conclusion. Working as a fraud analyst requires an eye for detail and an inquisitive mind. Individuals in these positions must be able to investigate fraud cases from beginning to end and dissect the nature of potential crimes. It is hard work, as it takes a lot of training to be able to succeed in this role.
Statisticians use mathematical techniques to analyze and interpret data and draw conclusions. Although they work mostly in offices, they may travel in order to supervise surveys or gather data. Sometimes they must work overtime to meet deadlines. About one-third of statisticians work for government; many others work for private businesses.
Industrial-Organizational psychology is an area of psychology that focuses on studying people in their working environment. The role can also involve focusing on workplace dynamics and organizational structures. Through the use of industrial-organizational psychologists, work places can improve the success of their organization. Industrial-organizational psychology first began in the earlier 20th century when it was found that troops returning from World War I needed therapy to regain morale. It wasn't until after World War II that the field really grew, and as the 20th century progressed the use of a industrial-organizational psychologist in the work place became more common. Industrial-organizational psychologists typically work either within an organization, or in the academic field. For industrial-organizational psychologists who have gained considerable experience, consulting opportunities are available. Those who work as an industrial-organizational psychologist can expect to spend a lot of time working with statistics. As developing initiatives on behalf of businesses depends on science-based research, the industrial-organizational psychology relies heavily on working with large numbers.
Veterinarians are medical professionals who protect the health and well-being of both animals and people. They diagnose and control animal diseases and treat sick and injured animals.
