Communication of the Paleolithic age and the modern parallels.
Introduction
The history of communication dates back to prehistory, with significant changes in communication technologies (media and appropriate inscription tools) evolving in tandem with shifts in political and economic systems, and by extension, systems of power. Communication can range from very subtle processes of exchange, to full conversations and mass communication. Human communication was revolutionized with speech approximately 100,000 years ago. Symbols were developed about 30,000 years ago, and writing about 5000 years ago.
Rock Art is a general term for all forms of humanly fashioned marks on lithic surfaces. The term is a general category that includes at least two distinctive types of art known as petroglyphs and pictographs.
Petroglyphs verses Pictographs
Petroglyphs
This type of rock art is the formation of images usually found from the Neolithic period, by people who incised or carved the rock surface. Often, these images were important forms of pre-symbol writing and were used in the earliest forms of communication and signage.
The two Greek words ‘petros’ and ‘glyphein’ which respectively mean ‘rock’ and ‘carve’ were first combined into the French language to form the single word petroglyphe.
Pictographs
A pictograph, or sometimes called a pictogramme, is an image that represents an object, activity, concept, event or a place or person by use of illustration. In contrast to petroglyphs, pictographs are a true form of symbolic writing where ideas are communicated through the drawing. Pictographs form the basis of the more famous hieroglyphs and the expansively used wedge-shaped cuneiform writing.
Many pictorial road signs, such as an image of a worker with a spade or a profile silhouette of children walking, are modern types of pictographs. In such instances they transmit a…...

Logic

...Logical Concepts an overview What is logic? •  Logic is the science of reasoning, •  which is to say: the academic discipline that investigates reasoning. What is reasoning? •  reasoning is inferring (deducing) •  to infer is to draw conclusions (output) from a premise or set of premises (input). An Example of Reasoning You see smoke And you infer That there is fire (input) (deduce) (output) Another example of Reasoning You count 19 people in a group; which originally had 20 people in it; and you infer that someone is missing (input) (input) (deduce) (output) The Basic Idea Logic evaluates reasoning in terms of arguments. What is an argument? •  The word “argument” can mean many different things depending on the context. •  But for the purposes of logic, the term “argument” means something very specific: What is an argument? •  an argument is a collection of statements, one of which is designated as the conclusion, and the remainder of which are designated as the premises. •  Important note: premises are always intended to provide support or evidence for the conclusion, but they don't always succeed. (It’s still an argument either way.) What is a statement? •  A statement is a declarative sentence, •  i.e., a sentence that is capable of being true or false. •  For example: The door is closed. •  Other kinds of sentence are not capable of being true or false: •  Interrogative sentences are inquiries for information: Is the......

Nature of Logic

...Nature of Logic to Critical Thinking Introduction Alliance in the workplace is inevitable as a successful working team member becomes familiar with each other. The leadership is defined and each member knows his or her function or responsibility. When problems arise that can cause deadlines to slip, the logical assumption by managers is to provide fresh insight to quickly get back on schedule. The next logical step is the introduction of a new member to that team that usually disrupts the harmony that previous success has generated and creates problems regardless of the qualification of the new member. Discussion Whenever a task is assigned with little or no margin for error and a deadline is missed, someone usually must be held accountable. This situation came about while integrating a new wireless communication system to an existing, but obsolete, hard-wired system. The time allocated to complete the integration was dependent on the assumption that it would be a seamless integration. A problem was immediately realized when the analysis of the wired and wireless system revealed that the wireless system is balanced, differential microphone and differential headsets do not share a common return, and the drive level in one direction was too low and too high in the other. Further complicating the problem was that the wired system was designed to operate with a powered microphone, needs dc voltage, and the wireless was not capable of generating that dc voltage level. ...

...Part one of the video opens up by telling viewers that Aristotle is credited with formalizing logic as a discipline. Viewers are directed to the aspect of what arguments are in the area of logic. Arguments are not heated exchanges or personal assaults, but however they are a group of statements. Statements are sentences capable of being true or false. An example of a statement is saying, “All cats are vicious animals.” The next topic that is brought up in part one of the video is the subject of inference. Inference is the reasoning process of an argument. Inference can be explicit (using premise and/or conclusion indicator words) and implicit (the reader has to catch the inference). Finally the video concludes with the point that there are four non-inferences commonly mistaken for arguments these are: advice, assertion, reports, and explanations. Part two of the formal logic video is the topic of inference. As stated in the early video inference is the reasoning process of an argument. Viewers are now introduced with the topic of deductive and inductive arguments. A deductive argument means that there is no possibility of the conclusion being false when the premises are true. Inductive arguments mean that the premises merely make the conclusion likely (conclusion “goes beyond” the premises). Lastly inductive forms are arguments based on signs, prediction, and generalization just to name a few. Part three of the video talks about validity, strength, soundness, and......

(1994). Understanding Global Cultures: Metaphorical Journeys Through 17 Countries. Thousand Oaks, CA: Sage. The Challenge of Crossing Cultural Boundaries In cross-border business, we step into different cultural environments characterized by unfamiliar languages and unique value systems, beliefs, and behaviors. We encounter customers and business partners who display differing lifestyles, norms, and consumption behaviors. These differences influence all dimensions of international business. Often, they get in the way of straightforward communication, representing one of the four risks associated with international business that we introduced in Chapter 1. We highlight these risks in Exhibit 5.1. Cross-cultural risk is defined as a situation or event where a cultural miscommunication puts some human value at stake. Cross-cultural risk arises routinely in international business because of the diverse cultural heritage of the participants. Culture refers to the learned, shared, and enduring orientation patterns in a society. People demonstrate their culture through values, ideas, attitudes, behaviors, and symbols. Culture affects even simple greetings and partings. Greeting ceremonies are a deeply embedded cultural marker and evolve over many centuries. They specify such behaviors......

...1.2.1.AK Combinational Logic Design Introduction Combinational and sequential logic are the fundamental building blocks of digital electronics. Combinational logic, which is sometimes referred to as "combinatorial logic”, is characterized by its output being a function of the current input value. A variety of different logic gates can be used to implement combinational logic circuits. Many of these gates will be studied in future units of this course. In this introductory unit, we will limit our designs to AND, OR, and INVERTER gates for the sake of simplicity. In this activity you will use the Circuit Design Software (CDS) to build and test your first combinational logic circuits. Equipment * Circuit Design Software (CDS) Procedure Now it’s time for you to implement your first AOI combinational logic circuit. The circuit that we will use for this purpose is a Car Safety Buzzer design.The design specifications are as follows: The buzzer is on whenever the door is open or when the key is in the ignition and the seat belt is not buckled. 1. Create a table that describes these design specification in terms of “highs” (1) and “lows” (0). This is when the sensor or indicator is active or not active. Seat Belt | 0 = SEAT BELT NOT BUCKLED | | 1 = SEAT BELT BUCKLED | Key | 0 = KEY NOT IN THE IGNITION | | 1 = KEY IN THE IGNITION | Door | 0 = DOOR IS NOT OPEN | | 1 = DOOR IS OPEN | Buzzer | 0 = BUZZER is OFF | | 1 = BUZZER is ON | 2.......

...deserve a second chance on a new planet." "Maybe so," Claudia says in a patronizing tone."And now that you mention it, we probably have a legal obligation to let them in. Our current immigration laws say that we have to admit at least ten thousand applicants annually, from every major nation. If those aliens would just sign the right papers, we'd have to give them permanent resi­ dency. However, what worries me is, they may have the wrong intentions. After all, didn't they conduct experiments on those people they abducted?" "Yes, but don't we experiment on animals? If the animals don't complain, why should we? Also, medical experimentation often leads to wonderful new cures. I'm certain we have nothing to worry about," says Ralph, proud of his logic. "Humph! I hope you're right. Well, I've got to go now-and don't let any green men kidnap you," Claudia says with a barb. "And you, either," Ralph answers. 3.4 Fallacies of Presumption, Ambiguity, and Grammatical Analogy The fallacies of presumption include begging the question, complex question, false dichotomy, and suppressed evidence. These fallacies arise not because the premises are irrelevant to the conclusion or provide insufficient reason for believing the conclusion but because the premises presume what they purport to prove. Begging the question presumes that the premises provide adequate support for the conclusion when in fact they do not, and complex question presumes that a question can be answered by a sim­ ple......

...Logic Application Project Student Name: _______________________, _______________________ Last Name First Name The Problem: How can you found out what cards you have? The Approach: First, we should examine the stated facts that Andy has the cards 1 3 7 while Belle has the cards 3 4 7 and Carol has the cards 4 6 8. Then the second thing we will look at is their answer on the question cards that they draw. Combining the information given and their answers on the question cards, we can figure out what is the connection of these to your own cards, and that’s how we will figure out what cards you have. Conclusion: First, by examining the stated facts that Andy has the cards 1 3 7 while Belle has the cards 3 4 7 and Carol has the cards 4 6 8, and the answer of Belle to his question card, knowing that she sees Andy, Carol and yours, she says that she sees all of them, the five odd numbers on the cards that she can see and Carol don’t have any odd number on her cards so the ones that are left is you and Andy. Andy has three odd numbers of each kind on his cards and that would leave a conclusion that you have two odd numbers on your cards. Looking back to the answer of Andy to the question “Do you see two or more players whose card sum to the same value?” and answered “Yes”, knowing that the cards he can see are yours, Belle and Carol, and the sum of Belle’s cards and Carol’s cards are not the same, we can conclude that one of them have...

... Logic Application After evaluating the game of “Guess your Card”, I assume that my cards could only be 4, 5, and 9. I came up with this logic by starting with Andy. I add all three numbers together from each player. Andy has the cards of 1, 3, and 7 with a sum of 11. Belle has the cards 3, 4, and 7 with a sum of 14, and Carol has the cards 4, 6 and 8 with a sum of 18. Since each player have a different sum I took the players with the highest sum which is Belle and Carol to see which player cards would add up with my cards. Next, Belle draw the question card, “of the five odd numbers”, how many different odd numbers do you see? She answer all of them. Only because the only odd numbers she see is from Andy and Carol which are 1, 3, and 7. That's how I came up with the numbers of 5 and 9. I then, add together 5 and 9 which is 14, let's not forget in the beginning I said the sums must add up to either 14 or 18. Since 5+9=14, and the smallest card is 1 so my cards must add up to more than 14. The sum of my cards must be 18. In order for me to find out what is my final card I must subtract 18 from 9 and 5 which gives me 4. You can also see why Andy knew what cards he had. He realize that the only odd numbers Belle could see from Carol and myself were 5 and 9, but yet she claim she could see all five odd numbers. So the remaining three: 1, 3 and 7 must have come from Andy himself. That's how he figure out what he had. The logic of......
