Organizational structure - Wikipedia. An organizational structure defines how activities such as task allocation, coordination and supervision are directed toward the achievement of organizational aims. The structure of an organization will determine the modes in which it operates and performs. Organizational structure allows the expressed allocation of responsibilities for different functions and processes to different entities such as the branch, department, workgroup and individual. Organizational structure affects organizational action in two big ways: First, it provides the foundation on which standard operating procedures and routines rest. Second, it determines which individuals get to participate in which decision- making processes, and thus to what extent their views shape the organization. Organizational structure was considered a matter of choice.. When in the 1. 93. Such divergence decreases performance, when growing. ![]() E. g., a wrong organizational structure may hamper cooperation and thus hinder the completion of orders in due time and within limits of resources and budgets. Organizational structures should be adaptive to process requirements, aiming to optimize the ratio of effort and input to output. Pre- bureaucratic structures. This structure is most common in smaller organizations and is best used to solve simple tasks. The structure is totally centralized. The strategic leader makes all key decisions and most communication is done by one on one conversations. It is particularly useful for new (entrepreneurial) business as it enables the founder to control growth and development. They are usually based on traditional domination or charismatic domination in the sense of Max Weber's tripartite classification of authority. Bureaucratic structures. Precision, speed, unambiguity, . They are better suited for more complex or larger scale organizations, usually adopting a tall structure. The tension between bureaucratic structures and non- bureaucratic is echoed in Burns and Stalker's. Since there are many levels, decision- making authority has to pass through more layers than flatter organizations. A bureaucratic organization has rigid and tight procedures, policies and constraints. This kind of structure is reluctant to adapt or change what they have been doing since the company started. Organizational charts exist for every department, and everyone understands who is in charge and what their responsibilities are for every situation. Decisions are made through an organized process, and a strict command and control structure is present at all times. In bureaucratic structures, the authority is at the top and information is then flowed from top to bottom. This causes for more rules and standards for the company which operational process is watched with close supervision. Some advantages for bureaucratic structures for top- level managers are they have a tremendous control over organizational structure decisions. This works best for managers who have a command and control style of managing. Strategic decision- making is also faster because there are fewer people it has to go through to approve. Some disadvantages in bureaucratic structures are it can discourage creativity and innovation in the organization. This can make it hard for a company to adapt to changing conditions in the marketplace. Post- bureaucratic. This may include total quality management, culture management and matrix management, amongst others. None of these however has left behind the core tenets of Bureaucracy. Hierarchies still exist, authority is still Weber's rational, legal type, and the organization is still rule bound. ![]() In computing, a persistent data structure is a data structure that always preserves the previous version of itself when it is modified. Such data structures are. Data Structures In C++ Tutorial: Writing Data Structures using OOP in C++. Data Structures and Algorithms in Python Michael T. Goodrich Department of Computer Science University of California, Irvine Roberto Tamassia Department of Computer. Abacus Shade Structures is a manufacturer, designer and installer of quality shade structures, sails and membrane structures in shade cloth or waterproof materials. ![]() Heckscher, arguing along these lines, describes them as cleaned up bureaucracies. Gideon Kunda, in his classic study of culture management at 'Tech' argued that 'the essence of bureaucratic control - the formalization, codification and enforcement of rules and regulations - does not change in principle... Another smaller group of theorists have developed the theory of the Post- Bureaucratic Organization.. Charles Heckscher has developed an ideal type, the post- bureaucratic organization, in which decisions are based on dialogue and consensus rather than authority and command, the organization is a network rather than a hierarchy, open at the boundaries (in direct contrast to culture management); there is an emphasis on meta- decision- making rules rather than decision- making rules. This sort of horizontal decision- making by consensus model is often used in housing cooperatives, other cooperatives and when running a non- profit or community organization. It is used in order to encourage participation and help to empower people who normally experience oppression in groups. Still other theorists are developing a resurgence of interest in complexity theory and organizations, and have focused on how simple structures can be used to engender organizational adaptations. For instance, Miner et al. Their study makes links to simple structures and improviser learning. Other scholars such as Jan Rivkin and Sigglekow. The organizational structure determines how the organization performs or operates. The term organizational structure refers to how the people in an organization are grouped and to whom they report. One traditional way of organizing people is by function. Some common functions within an organization include production, marketing, human resources, and accounting. This organizing of specialization leads to operational efficiency where employees become specialists within their own realm of expertise. The most typical problem with a functional organizational structure is however that communication within the company can be rather rigid, making the organization slow and inflexible. Therefore, lateral communication between functions become very important, so that information is disseminated, not only vertically, but also horizontally within the organization. Communication in organizations with functional organizational structures can be rigid because of the standardized ways of operation and the high degree of formalization. As a whole, a functional organization is best suited as a producer of standardized goods and services at large volume and low cost. Coordination and specialization of tasks are centralized in a functional structure, which makes producing a limited amount of products or services efficient and predictable. Moreover, efficiencies can further be realized as functional organizations integrate their activities vertically so that products are sold and distributed quickly and at low cost. Such groups may have difficulty working well with each other as they may be territorial and unwilling to cooperate. The occurrence of infighting among units may cause delays, reduced commitment due to competing interests, and wasted time, making projects fall behind schedule. This ultimately can bring down production levels overall, and the company- wide employee commitment toward meeting organizational goals. Divisional structure. A division is a collection of functions which produce a product. It also utilizes a plan to compete and operate as a separate business or profit center. According to Zainbooks. America is seen as the second most common structure for organization today. Examples of divisions include regional (a U. S Division and an EU division), consumer type (a division for companies and one for households), and product type (a division for trucks, another for SUVS, and another for cars). The divisions may also have their own departments such as marketing, sales, and engineering. The advantage of divisional structure is that it uses delegated authority so the performance can be directly measured with each group. This results in managers performing better and high employee morale. Also, a company will have a simpler process if they need to change the size of the business by either adding or removing divisions. When divisional structure is utilized more specialization can occur within the groups. When divisional structure is organized by product, the customer has their own advantages especially when only a few services or products are offered which differ greatly. When using divisional structures that are organized by either markets or geographic areas they generally have similar function and are located in different regions or markets. This allows business decisions and activities coordinated locally. The disadvantages of the divisional structure is that it can support unhealthy rivalries among divisions. This type of structure may increase costs by requiring more qualified managers for each division. Also, there is usually an over- emphasis on divisional more than organizational goals which results in duplication of resources and efforts like staff services, facilities, and personnel. Matrix structure. This structure can combine the best of both separate structures. A matrix organization frequently uses teams of employees to accomplish work, in order to take advantage of the strengths, as well as make up for the weaknesses, of functional and decentralized forms. An example would be a company that produces two products, . Using the matrix structure, this company would organize functions within the company as follows: . The Data.Map module provides a Map type with behavior that is similar to association lists, but has much better performance. Maps give us the same capabilities. The functional managers maintain control over their resources and project areas. Balanced/Functional Matrix: A project manager is assigned to oversee the project. Power is shared equally between the project manager and the functional managers. It brings the best aspects of functional and projectized organizations. However, this is the most difficult system to maintain as the sharing of power is a delicate proposition. Strong/Project Matrix: A project manager is primarily responsible for the project. Functional managers provide technical expertise and assign resources as needed. Matrix structure is only one of the three major structures. The other two are Functional and Project structure. Clojure - Rationale. Customers and stakeholders have substantial investments in, and are comfortable with the performance, security and stability of, industry- standard platforms like the JVM. While Java developers may envy the succinctness, flexibility and productivity of dynamic languages, they have concerns about running on customer- approved infrastructure, access to their existing code base and libraries, and performance. In addition, they face ongoing problems dealing with concurrency using native threads and locking. Clojure is an effort in pragmatic dynamic language design in this context. It endeavors to be a general- purpose language suitable in those areas where Java is suitable. It reflects the reality that, for the concurrent programming future, pervasive, unmoderated mutation simply has to go. Clojure meets its goals by: embracing an industry- standard, open platform - the JVM; modernizing a venerable language - Lisp; fostering functional programming with immutable persistent data structures; and providing built- in concurrency support via software transactional memory and asynchronous agents. The result is robust, practical, and fast. Clojure has a distinctive approach to state and identity.

This marks a largely symbolic shift in public position; Congress nixed its plan to add women to Selective Service registration two days before Obama’s declaration of support. The Associated Press reports that Obama has been considering the issue of women in the draft since Secretary of Defense Ash Carter opened all combat positions to women almost exactly one year ago. Historically, every time drafting women has become an issue of public debate, those who oppose gender- neutral Selective Service have invoked a 1. Supreme Court decision that exempted women from the draft because they didn’t serve on the front lines. Now that they do, the only reasons left for excluding women rest on sexist ideas of what kind of people are competent in battle, whose duty it is to protect, and who must be protected. A White House National Security Council spokesman told the APthat Obama thinks women have “proven their mettle” in battle, so it makes no sense to draw gender barriers around the draft. The Pentagon’s press secretary said Carter agrees with the president that women should be drafted if the draft is ever reinstated—it’s been inactive since the Vietnam War—since the military has been strengthened by adding women to combat positions, thus widening the pool of qualified applicants. Top military officials and veterans in both political parties, including Republican Sen. John Mc. Cain, have said including women in the draft is only fair. Earlier this year, it looked like Congress was poised to ax one of the few remaining barriers to women’s inclusion in the military. In June, the Senate passed a version of the National Defense Authorization Act that included a provision for an all- gender draft with a vote of 8. That provision made it into the House of Representatives’ version, but by the time it got to the floor for a vote, it had been removed. Instead, the final version of the legislation will commission a review of the Selective Service System to see if it’s still necessary or practical to keep the draft as an option at all. The push to include women in the draft likely failed because it was a bigger deal to legislators and constituents who opposed it than to those who supported it. Making the draft gender- neutral would make sense given the current state of the military and combat roles, but since the draft is unlikely to return anytime soon, it would matter more as a vote of confidence in gender equality than as a practical concern. Meanwhile, conservatives have made this largely hypothetical conversation a wedge issue about protecting women. Ben Sasse of Nebraska, who might have wanted to shore up support from deplorables while railing against Donald Trump in the lead- up to the election, has been among the loudest opponents of adding women to the draft. On Tuesday, he said keeping the draft men- only will “put national security ahead of unnecessary culture- warring,” thus avoiding “a fight about drafting our mothers, sisters, and daughters.”Ted Cruz, too, has made himself a visible warrior against women in the draft. At a presidential campaign rally in February, he mock- addressed his fellow Republican candidates who would require women to register for Selective Service. Political correctness is dangerous. And the idea that we would draft our daughters to forcibly bring them into the military and put them in close combat, I think, is wrong. It is immoral.” Here, Cruz made the classic right- wing argument used to turn conservative women against feminism: that men and women are not equal, and that women should be protected.

It’s the same argument Paul Ryan made when he responded to Donald Trump’s “grab them by the pussy” statement by saying that women should be “championed and revered” instead of objectified. That’s giddy Trump supporter Paul Ryan, promising to protect women while endorsing for president a man who brags about assaulting them. At the February rally, Cruz used his daughters as reasons why including women in the draft would be stupid and cruel. But the idea that their government would forcibly put them in a foxhole with a 2. What an apropos line of reasoning! The idea that legislators who send America’s troops to war would have to contend with the consequences of sending their own children into harm’s way is one of the main reasons for keeping the specter of an income- and status- blind draft around in the first place. ![]() At SRAM we are passionate about cycling.

This. type of speaker illuminates the listening room uniformly and the perceived sound. The result can be quite. The speakers tend to disappear. Unfortunately, the direct sound is. The typical box speaker, whether vented, band- passed or. Even when flat on- axis, the. B (1. 0x) or more. The uneven power response and the associated. This cannot be the avenue to. The directional response of the ideal dipole is obtained. Note, that to obtain the same. This means 4. 8 d. B less contribution. It might also mean 4. B less sound for your neighbor, or that much more sound to you. Despite this. advantage dipole speakers are often not acceptable, because they tend to be. Because of the progressive acoustic short. SPL at. the listening position. This demands a large radiating surface area, because. The obtained volume displacement limits the maximum bass output. Such. speakers were built by Audio Artistry Inc. This type of speaker has a much more. Not only is its bass output. My hypothesis is that three effects combine to produce. An open baffle, dipole speaker has a figure- of- eight radiation pattern and. Its total radiated power is 4. B less than that of a monopole for the same. SPL. Thus the strength of the excited modes is less. A 4. 8 d. B difference in SPL at low frequencies is quite significant, due to. B difference in loudness at 1 k. Hz. Thus, bass reproduced by a dipole would be less masked by the room, since a. The off- axis radiation behavior of a speaker determines. Worst in this respect is the typical box speaker, followed. Least. affected is the sound of the open- baffle speaker with piston drivers. Cancellation can only occur when direct. Since direct and reflected sounds travel paths of different length. Thus, the phase and magnitude. At. some other frequencies direct and reflected sounds will add. The same also. applies to a monopole speaker in front of a wall. The only difference is in the. The best remedy is to move. The following discussion might get a. As the cone vibrates it will send out an acoustic wave which gets. If the frequency of vibration is such. L corresponds to half of a wavelength, then the cone movement. As frequency is increased another resonance occurs when L equals to a full. The lowest possible frequency. L) Hz, where c=3. If the excitation is applied as a step function, then the. Trise = 0. 7 / BW (2) where BW is the width of the resonance curve in Hz at the. B) level. The SPL will decay to one thousand's (- 6.

At frequencies below the lowest room resonance the sound. B/oct for a closed box speaker that is. This case has some significance for the interior of. Under the same circumstances the sound from a dipole speaker will. Domestic listening spaces are seldom completely closed, nor are sheet rock walls. Note: Calculations of room modes, though popular, are not. For this one would. The. transfer function is related to the room modes, but much more difficult to. Never- the- less, room mode calculations are often invoked to predict. They fail to take into account any. Some people think that by making the room other than rectangular or. They merely. change frequencies, shift their distribution and make their calculation a lot. Room modes can be identified by peaks and dips in the. Hz) where their. density is not too high. Such measurements are location dependent and are. Listening to a multi- burst. Ref. 1). With this. Several room parameters can be calculated that give.
