Industrial production managers coordinate the resources and activities required to produce millions of goods every year in the United Sates. Although their duties vary from plant to plant, industrial production managers share many of the same major responsibilities. These responsibilities include production scheduling, staffing, procurement and maintenance of equipment, quality control, inventory control, and the coordination of production activities with those of other departments.The primary mission of industrial production managers is planning the production schedule within budgetary limitations and time constraints. They do this by analyzing the plant’s personnel and capital resources to select the best way of meeting the production quota. Industrial production managers determine, often using mathematical formulas, which machines will be used, whether new machines need to be purchased, whether overtime or extra shifts are necessary, and what the sequence of production will be. They monitor the production nm to make sure that Ft stays on schedule and correct any problems that may arise.Industrial production managers also must monitor product standards. When quality drops below the established standard, they must determine why standards are not being maintained and how to improve the product. If the problem relates to the quality of work performed in the plant, the manager may implement better training programs, reorganize the manufacturing process, or institute employee suggestion or involvement programs. If the cause is substandard materials, the manager works with the purchasing department to improve the quality of the product’s components.Because the work of many departments is interrelated, managers work closely with heads of other departments such as sales, procurement, and logistics to plan and implement company goals, policies, and procedures. For example, the production manager works with the procurement department to ensure that plant inventories are maintained at their optimal level. This is vital to a firm’s operation because maintaining the inventory of materials necessary for production ties up the firm’s financial resources, yet insufficient quantities cause delays in production. A breakdown in communications between the production manager and the purchasing department can cause slowdown and a failure to meet production schedules. Just-in-time production techniques have reduced inventory levels, making constant communication among the manager, suppliers, and purchasing departments even more important. Computers play an integral part in this coordination. They also are used to provide up-to-date information on inventory, the status of work in progress, and quality standards.Production managers usually report to the plant manager or the vice president for manufacturing, and may act as liaison between executives and first-line supervisors. In many plants, one production manager is responsible for all aspects of production. In large plants with several operations-there are managers in charge of each operation, such as machining, assembly, or finishing. What is the role of computers in the production process()
A. They Control the techniques of production.
B. They keep each department well-informed.
C. They monitor the progress and status of work.
D. They transmit directions from the management to employees.

Linguists have understood for decades that language and thought are closely related. Humans construct reality using thought and express these thoughts through the use of language. Edward Sapir and his student Benjamin Whorf are credited with developing the most relevant explanation outlining the relationship between thought and language, the Sapir-Whorf Hypothesis. The hypothesis consists of two parts, linguistic relativity and linguistic determinism. Supporters of linguistic relativity assume that culture is shaped by language. Terwilliger defines linguistic determinism as the process by which "the functions of one’s mind are determined by the nature of the language which one speaks." In simpler terms, the thoughts that we construct are based upon the language that we speak and the words that we use. In its strongest sense, linguistic determinism can be interpreted as meaning that language determines thought. In its weakest sense, language partially influences thought. Whorf was careful to avoid authoritative statements which would permanently commit him to particular position.Because of the broad nature of his statements, it is difficult to distinguish exactly to what extent Whorl Believes that language determines thought. Heated debate among modem linguists demonstrates that disagreement exists about the accuracy and correctness of Whorf’s studies and of the actual level of influence of language on thought processes.The Sapir-Whorf Hypothesis essentially consists of two distinct statements connecting the relation of thought and language. Whorf believes that humans may be able to think only about objects, processes, and conditions that have language associated with them. The Sapir-Whorf Hypothesis also explains the relationship between different languages (French, English, German, Chinese, and so on)and thought. Whorf demonstrated that culture is largely determined by language. Different cultures perceive the world in different ways. Culturally essential objects, conditions and processes usually are defined by a plethora of words, while things that cultures perceive as unimportant are usually assigned one or two words. Whorf developed this theory while studying the Hopi Indian tribe. Whorf was amazed that the Hopi language has no words for past, present, and future. The Hopi have only one word for flying objects. A dragonfly, an airplane, and a pilot are defined using the same word. Whorf questioned whether or not the Hopi view the world differently than western peoples. After hither interpretation and analysis he concluded that the Hopi have a sense for the continuum of time despite having no words to specifically describe past, present, and future.It is commonly believed that the Sapir-Whorf Hypothesis possesses some truth, but the extent to which it is applicable to all situations is questioned. Linguists generally support a "strong" or a "weak" interpretation. Linguists who study the hypothesis tend to cite examples that support their beliefs but are unable or unwilling to refute the opposing arguments. Examples exist that strengthen the arguments of ev0eryone who studies the hypothesis. Nobody has gained significant ground in proving or refuting the hypothesis because the definitions of Sapir and Whorl are very vague and incomplete, leaving room for a significant amount of interpretation. Whorf himself tends to hold that ()
A. culture is shaped by language
B. language determines thought
C. language partially influences thought
D. thoughts are based on language
Distance education is enrollment and study with an educational institution that provides lesson materials prepared in a sequential and logical order for study by students on their own. When each lesson is completed, the student mails or transmits the assigned work to the institution for correction, grading, comment, and subject matter guidance by qualified instructors. Corrected assignments are returned promptly to the student. This exchange provides a personalized student-teacher relationship. If a student slows his or her pace or fails to send assignments, the school provides encouragement. Although some institutions provide employment placement information and assistance, no reputable school ever guarantees a job to graduates.Distance education and self-study are different. Self-study materials provide no instructional service. Corrected assignments, examinations, and special help provided by a qualified facility are vital to a good learning situation. However, these are not part of self-study. There are many self-study courses and recordings available, and they may have value, but they clearly are not correspondence or distance education courses. Some institutions offer combination courses that provide training-in-residence for students who complete their distance education lessons. In-service or on-the-job training is required or provided with other courses and is a feature of many vocational distance education programs.Quality distance education institutions screen prospective students to assure that only those who can benefit from the courses are enrolled. While there are educational prerequisites for some academic subjects, interest and aptitude are the primary factors leading to success in most distance education courses. Because they provide alternative educational opportunities, distance education institutions try not to deny a prospective student the opportunity to succeed in a course- interest and experience are good indicators of future success.Distance education courses vary greatly in scope, level, and length. Some have few lessons and require only weeks to complete, while others have a hundred or more assignments requiring three or four years of conscientious study. Also, a wide variety of subjects is offered. Subjects include yacht design, accounting, medical transcription, nutrition, robotics, travel agent training, gun-repair, gem identification, computer programming, catering and cooking, and earning an entire high school diploma, just to name a few.There is an increasing recognition of "distance education" and many colleges offer credit for their distance learning courses or accept some distance education credits of resident students working toward a degree. In fact, many distance education institutions award their own academic degrees. Acceptance of students and awarding of academic credit is the prerogative of the receiving academic institution. Also, the employing organization may set its own credit acceptance policies. It is implied in the passage that students of distance education ()
