The rich analysts of Fernand Braudel arid his fellow Annales historians have made significant contributions to historical theory and research. In a departure from traditional historical approaches, the Annales historians assume (as do Marxists) that history cannot be limited to a simple recounting of conscious human actions, but must be understood in the context of forces and material conditions that underlie human behavior. Braudel was the first Annales historian to gain widespread support for the idea that history should synthesize data from various social sciences, especially economics, in order to provide a broader view of human societies over time (although Febvre and Bloch, founders of the Annales school, had originated this approach). Braudel conceived of history as the dynamic interaction of three temporalities. The first of these, the evenmentielle, involved short-lived dramatic events such as battles, revolutions, and the actions of great men, which had preoccupied traditional historians like Carlyle. Conjonctures was Braudel’s term for larger cyclical processes that might last up to half a century. The longue duree, a historical wave of great length, was for Braudel the most fascinating of the three temporalities. Here he focused on those aspects of everyday life that might remain relatively unchanged for centuries. What people ate, what they wore, their means and routes of travel—for Braudel these things create “structures’ that define the limits of potential social change for hundreds of years at a time. Braudel’s concept of the longue duree extended the perspective of historical space as well as time. Until the Annales school, historians had taken the juridical political unit—the nation-state, duchy, or whatever—as their starting point. Yet, when such enormous timespans are considered, geographical features may well have more significance for human populations than national borders, In his doctoral thesis, a seminal work on the Mediterranean during the reign of Philip II, Braudel treated the geohistory of the entire region as a “structure” that had exerted myriad influences on human lifeways since the first settlements on the shores of the Mediterranean Sea. And so the reader is given such arcane information as the list of products that came to Spanish shores from North Africa, the seasonal routes followed by Mediterranean sheep and their shepherds, and the cities where the best ship timber could be bought. Braudel has been faulted for the imprecision of his approach. With his Rabelaisian delight in concrete detail, Braudel vastly extended the realm of relevant phenomena but this very achievement made it difficult to delimit the boundaries of observation, a task necessary to beginning any social investigation. Further, Braudel and other Annales historians minimize the differences among the social sciences. Nevertheless, the many similarly designed studies aimed at both professional and popular audiences indicate that Braudel asked significant questions that traditional historians had overlooked. 14) The primary purpose of the passage is to: a) show how Braudel’s work changed the conception of Mediterranean life held by previous historians. b) evaluate Braudel’s criticisms of traditional and Marxist historiography. c) contrast the perspective of the longue duree with the actions of major historical figures d) outline some of Braudel’s influential conceptions and distinguish them from conventional approaches. 15) The author refers to the work of Febvre and Bloch in order to: a) illustrate the limitations of the Annale tradition of historical interpretation. b) suggest the relevance of economics to historical investigation. c) debate the need for combining various sociological approaches. d) show that previous Annales historians anticipated Braudel’s focus on economics. 16) According to the passage, all of the following are aspects of Braudel’s approach to history EXCEPT that he: a) attempted to draw on various social sciences. b) studied social and economic activities that occurred across national boundaries. c) pointed out the link between increased economic activity and the rise of nationalism. d) examined seemingly unexciting aspects of everyday life. 17) In the third paragraph, the author is primarily concerned with discussing: a) Braudel’s fascination with obscure facts. b) Braudel’s depiction of the role of geography in human history. c) the geography of the Mediterranean region. d) the irrelevance of national borders. 18) The passage suggests that, compared with traditional historians, Annales/i> historians are: a) more interested in other social sciences than in history. b) critical of the achievements of famous historical figures. c) skeptical of the validity of most economic research. d) more interested in the underlying context of human behavior. 19) Which of the Following statements would be most likely to follow the last sentence of the passage? a) Few such studies however, have been written by trained economists. b) It is time, perhaps, for a revival of the Carlylean emphasis on personalities. c) Many historians believe that Braudel’s conception of three distinct “temporalities” is an oversimplification. d) Such diverse works as Gascon’s study of Lyon and Barbara Tuchman’s A Distant Mirror testify to his relevance. 20) The author is critical of Braudel’s perspective for which of the Following reasons a) It seeks structures that underlie all forms of social activity. b) It assumes a greater similarity among the social sciences than actually exists. c) It fails to consider the relationship between short-term events and long-term social activity. d) It rigidly defines boundaries for social analysis.

Topics: Structures, Arrays, Searching and Sorting Assume there is a small mobile computer device including a hard disk and a slot for a memory card. The device shall be used to backup photos e.g. during holiday. Every time a memory card is connected all photos of the card are copied into a new folder automatically. And your task is to develop some basic controlling software to show, add, remove, search and sort the directories of photos. Step by Step Implementation 1.Define two symbolic constants, one to hold the total volume of the disk (e.g. VOLUME) and another one to hold the number of entries the files system of the device can handle (MAXFOLD). 2.Define a new structure data type named DATE to store a date consisting of year, month and day as unsigned values. 3.Define an other structure data type FOLDER to store the information of one folder of photos: ◦A title as character array of appropriate length ◦The location (event) the photos are taken as character array of appropriate length ◦The date of the day the photos are copied to the disk using the just defined data type DATE ◦The number of photos as natural number ◦And the size of the folder in MB as floating point value 4.Define the following global variables and initialise them: ◦disk as an array with MAXFOLD elements of data type FOLDER ◦folders as natural value to count the number of folders currently stored at the disk (valid elements in the array) TEST: Now you should be able to compile the code the first time without any warning or error. In the menu only "p" to print and "q" to quit will work!. 5.Now complete the functions given by their prototype: float freeSpace ();The function has to calculate the sum of the size component of all elements currently stored in the disk array. The function shall return the free space of the disk by the difference between the available total volume and the calculated sum. TEST: To test this function you only need to uncomment printing the "statusline" at the function actionmenu(). Compare the calculated value with a manual calculation of the example values given above. unsigned isBefore (DATE, DATE);The function checks if one date is before the other. There are 3 different possibilities which have to be handled. Imagine for example these 3 different combinations of values: ◦2010-01-01 : 2010-01-02 ◦2010-01-01 : 2010-02-01 ◦2010-01-01 : 2009-01-01 The function shall just return the result of the comparison. unsigned isEqual (DATE, DATE);The function checks if one date is equal to the other, all components have to be compared. The function shall just return the result of the comparison. int findByDate (DATE);As the array is should be kept in order (sorted by date) implement a binary search for a folder by its date here. You need only to adapt the binary search we used in the exercise. Use the 2 comparing functions above where appropriate. The function shall return the index of the element which was found or -1. TEST: Now you can try searching a folder by date via the "s" in the menu. Activate the corresponding part in the main function. int isSpaceLeft (FOLDER);This function compares the free space of the disk with the size of folder given with the parameter list. The function shall return 1 if there is enough space to add the folder, otherwise 0 (just the result of the comparison). void SortByDate ();This function shall implement the InsertionSort using the component date as key. Use the provided algorithm/souce code of the exercise as template. If you need a comparison between dates, use the function isBefore you have written again. void addFolder (FOLDER);The function has to check if the disk has additional capacities to add the new folder (number of folders and space left). If at least one of these conditions is false print an error message and return -1. Else there has to be added an other test to avoid 2 folder elements with the same date (use the findByDate function here. If there is no folder with the new date simply attach the new folder at the end of the array and call the sorting algorithm afterwards to keep the order in the array. TEST: Now you can try to add a folder via the "a" in the menu. Activate the corresponding part in the main function. void delDir (int);This function removes one element of the disk array. The input parameter contains the index of the element to delete. Deletion can simply be done by moving all elements at the right one to the left (overwriting the element to delete. The function may get a -1. This has to be checked first (certainly there is nothing to delete then!) Don't forget to decrement the counter of elements at the end. TEST: Now you can try to remove a folder by date via the "r" in the menu. Activate the corresponding part in the main function. unsigned findAllOfLocation(char[], FOLDER[]);This is an optional additional task: The function shall find all elements with the given value for the component location (first input parameter). The array elements which are found have to be added to the FOLDER array (second input parameter). As this parameter is an array we can use the result later in the main function. There kernel of function implements a modified linear search on the disk array (it does not stop if one element is found bat continues search until the location of all elements is checked). The finally function shall return the number of elements found in the disk array. TEST: Now you can try to add a folder by date via the "l" in the menu. Activate the corresponding part in the main function.
