Essay on Rewriting History in Henry IV -- Henry IV Henry V Essays

Rewriting History in Henry IV      Ã‚  Ã‚  Ã‚  Ã‚   The master of historiography is, perhaps, Shakespeare as evidenced by his History Plays. Whereas most writers merely borrow from history to fuel their creative fires, Shakespeare goes so far as to rewrite history. The First Part of Henry the Fourth follows history fairly closely, and Shakespeare draws this history primarily from Raphael Holinshed's Chronicle of England, Scotland, and Ireland and from Samuel Daniel's verse epic The Civil Wars (Abrams 823).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The play opens shortly after Henry Bolingbroke has usurped the throne from Richard II, becoming the fourth King Henry, and changing the royal lineage from the House of Plantagenet to the House of Lancaster. In the opening sequence, Henry IV is in the process of vowing peace in England and promising a crusade to liberate the Holy Land. No motive for this crusade surfaces in 1 Henry IV, other than the fact that it is some unfinished business from Shakespeare's preceding play Richard II (Kelly 214). Henry's pledge of civil peace is ironic because during this first scene he receives word that his troops have been overtaken by Glendower in Wales, and Hotspur has met and defeated the Scots in the North (1.1.36-61). To the news, the King replies, "It seems then that the tidings of this broil / Brake off our business for the Holy Land" (1.1.47-8). Postponing the business in Jerusalem, Henry IV eventually leads England into civil war with Hotspur a t the Battle of Shrewsbury. These actions will ultimately ignite the War of the Roses between the Lancasters (Henry IV's family) and the Yorks (descendants of Richard II).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The play then shifts its focus to the younger Henry, nicknamed Hal. Shakespeare portrays the ... ... as king. Shakespeare the Historian is not so wonderful as Shakespeare the Playwright, yet through Shakespeare's History Plays many modern readers draw their knowledge of the history prior to Shakespeare.    Works Cited * Drabble, Margaret, ed.

Leadership Style and Performance Essay

An overview of the topic of leadership styles summarizes that the existing studies on how performance is affected by leadership style is separated into important phases. Early studies on leadership (frequently categorized as ‘trait’ studies on leadership) concentrated on identifying the personality traits which characterized successful leaders (Argyris, 1955; Mahoney et al. , 1960). According to them successful leaders are ‘naturally born’ and those they have certain native characteristics which distinguish them from non-leaders (see Stodgill, 1948). However, there was significant difficulty in validating these characteristics led to widespread criticism of this trait approach, signaling the emergence of ‘style’ and ‘behavioral’ approaches to leadership (Stodgill, 1948). Style and behavioral theorists shifted the emphasis away from the characteristics of the leader to the behavior and style the leader adopted. The primry conclusion of these studies is that adoption of democratic or participative styles by leaders are more successful (see, for example, Bowsers and Seashore, 1966). In this sense, these early studies are focused on identifying the ‘one best way of leading’. Similarly to trait theories, the major weakness of style and behavioral theories is the ignorance of how important role situational factors play in determining the effectiveness of individual leaders (Mullins, 1999). It is this limitation that gives rise to the ‘situational’ and ‘contingency’ theories of leadership (for example, Fiedler, 1967; House, 1971; Vroom and Yetton, 1974) which shift the emphasis away from ‘the one best way to lead’ to context-sensitive leadership. Although each study emphasizes the importance of different factors, the general tenet of the situational and contingency perspectives is that leadership effectiveness is dependent on the leader’s diagnosis and understanding of situational factors, followed by the adoption of the appropriate style to deal with each circumstance. However, recent studies on leadership have contrasted ‘transactional’ leadership with ‘transformational’. Transactional leaders are said to be ‘instrumental’ and frequently focus on exchange relationship with their subordinates. In contrast, transformational leaders are argued to be visionary and enthusiastic, with an inherent ability to motivate subordinates. Although the brief summary above indicates that research into leadership has gone through periods of skepticism, recent interest has focused on the importance of the leadership role to the success of organizations. Fiedler (1996), one of the most respected researchers on leadership, has provided a recent treatise on the importance of leadership by arguing that the effectiveness of a leader is a major determinant of the success or failure of a group, organization or even an entire country. It has been argued that one way in which organizations have sought to cope with the increasing volatility and turbulence of the external environment is by training and developing leaders and equipping them with the skills to cope. These claims are based on the assumption of a direct link between leadership and organizational performance. This assumption requires critical review. Widely celebrated cases of a direct leadership–performance link may be found in numerous anecdotal accounts of improvements of company performance attributed to changes in leadership (see, for example, Nicholls, 1988; Quick, 1992; Simms, 1997). However, empirical studies into the links between leadership and performance have been lacking. One notable exception is the detailed study of the impact of leadership on performance in the somewhat surprising context of Icelandic fishing ships. Thorlindsson (1987) suggests that variations in the performance of different fishing ships, under identical conditions, can be accounted for by the leadership skills of captains. Over a three-year period, Thorlindsson revealed that the leadership qualities of the ship captains accounted for 35 to 49 per cent of variation in the catch of different crews. Other studies which examine the links between leadership and performance coincide with the re-emergence of the ‘one best way to lead’ debate. Of particular relevance is the resurgence of interest into charismatic leadership, which is frequently referred to as transformational leadership (Bass and Avolio, 1993). A number of researchers theorize that transformational leadership is linked to organizational performance. Conceptually, it is argued that the visionary and inspirational skills of transformational leaders motivate followers to deliver superior performance. In summary, much of the above evidence presented as supporting the claim of a leadership–performance link is anecdotal and frequently over-concentrates on the ‘transformational’ role of leaders in corporate successes. It would appear that few studies have responded to the observation of Porter and Mckibbin (1988) that much of the research reported as supporting this claim is either inconclusive or empirically suspect. The limited or inconclusive character of research findings in this area suggests the need to investigate further the nature of the relationship between leadership and performance. Several different categories of leadership paradigms have been suggested by various researchers. For example, Bass (1985) stated that there are four dimensions of transformational leadership, three dimensions of transactional leadership, and a non-leadership dimension of laissez-faire leadership (Bass, 1985). Avery (2004) suggested categorizing leadership into four leadership paradigms, while Goleman (1995) prefers six leadership paradigms. Despite Bass’s (1985) model being acclaimed as making a major contribution to leadership, his theory has been criticized for various reasons (Yukl, 1999). One criticism is that his model overemphasizes the importance of one or two leadership paradigms (e. g. transactional and visionary), omitting the classical and organic paradigms Bass asserts that visionary (transformational) leaders are nearly always more effective than transactional leaders, but others (e. g. Judge and Piccolo, 2004; Wallace, 1997) dispute this. While this in itself does not invalidate the concept of visionary leadership, Bass attributes more to visionary (transformational) leadership than perhaps he should. As Avery (2004) suggested, both transactional and visionary leadership are valid forms of leadership, but visionary leadership may be applicable more broadly, including in situations where there are insufficient resources for the manager to rely on supplying external rewards (Judge and Piccolo, 2004), or where the situation is complex and ambiguous, and relies strongly on follower knowledge and commitment. Avery suggests that there are other situations in which transactional leadership is the appropriate form of leadership, such as when followers are unwilling or unable to commit to the leader’s vision. In contrast with Bass’s (1985) model, Avery’s (2004) paradigms provide a broad basis allowing for different forms of leadership that have evolved at different times and in different places. The paradigms are useful for showing that there is no single best way of thinking about leadership, rather that different kinds of leadership reflect social and historical roots. Avery’s paradigms allow leadership to depend on the context, respond to organizational needs and preferences, and involve many interdependent factors that can be manipulated (Bryman, 1992; Shamir and Howell, 1999; Yukl, 1999). Avery (2004) proposes 13 indices to differentiate between her four paradigms: classical, transactional, visionary, and organic. The nine indices included in this review are decision making, range of staff’s power, power distance between leader and the staff, key player of the organization, source of staff’s commitment, staff’s responsibility, situation of management and leadership in the organization, situation of diversity in the organization and situation of control in the organization. These nine criteria are considered more relevant for differentiating the four leadership paradigms than the other four criteria. Each paradigm is discussed in turn, including the distinguishing characteristics using the above nine criteria. Classical leadership is probably the oldest paradigm with its origins in antiquity, and is still used in contemporary organizations (Avery, 2004). This paradigm reflected the prevailing view in the business literature until the 1970s when the human relations movement led to more of a focus on followers and their environment. According to Avery (2004), classical leadership refers to dominance by a pre-eminent person or an ‘elite’ group of people. This leadership can either be coercive or benevolent or a mixture of both. This happens because the elite individual or group commands or maneuvers other members to act towards a goal, which may or may not be explicitly stated. The other members of the society or organization typically adhere to the directives of the elite leader, do not openly question their directives, and execute orders largely out of fear of the consequences of not doing so, or out of respect for the leader, or both (Avery, 2004). Classical leadership has some limitations. The first occurs where the leader cannot command and control every action, particularly as situations become more complex and beyond the capacity of one person; or when additional commitment from followers is needed to get a job done, such as in reacting to changing circumstances; or when ideas about leadership change and followers no longer accept domination, or follower commitment starts to wane for other reasons. Another limitation is that this paradigm often relies on the idea of a ‘great person’, implying that only a select few are good enough to exercise initiative, and this belief can encourage followers to deskill themselves nd idealize the leaders. Followers then seek and hold little power, leave the leader accountable for organizational outcomes, and make relatively little contribution to the organization (Avery, 2004). According to the nine distinguishing indicators, under the classical leadership paradigm leaders normally use an autocratic style for making decisions, involving followers in the decision making process never or very little; they do not empower followers. Followers have almost no power in the organization and as classical leaders tend to be highly directive, followers can be unskilled. The source of followers’ commitment comes from their fear of or respect for the leaders; the technical system becomes more regulating; the operations in the organization become more routine and predictable; and the organization is highly controlled by the leaders (Avery, 2004). A transaction or exchange process is the basis of the commonly employed transactional leadership paradigm (Evans and Dermer, 1974; House and Mitchell, 1974). The transactional leader recognizes subordinates’ needs and desires, and then clarifies how those needs and desires will be met in exchange for subordinates’ work. By clarifying what is required of subordinates and the consequences of their behaviors, transactional leaders are able to build confidence in subordinates to exert the necessary effort to achieve expected levels of performance. According to Judge and Piccolo (2004), three dimensions of transactional leadership are contingent reward, management by exception-active, and management by exception-passive. Contingent reward is the degree to which the leader sets up constructive transactions or exchanges with followers. The leader clarifies expectations and establishes the rewards for meeting these expectations. In general, management by exception is the degree to which the leader takes corrective action on the basis of results of leader-follower transactions (Judge and Piccolo, 2004). As noted by Howell and Avolio (1993), the difference between management by exception-active and management by exception-passive lies in the timing of the leader’s intervention. Active leaders monitor follower behavior, anticipate problems, and take corrective actions before the behavior creates serious difficulties. Passive leaders wait until the behavior has created problems before taking action (Howell and Avolio, 1993; Judge and Piccolo, 2004). According to Avery (2004, p. 34), under the transactional leadership paradigm, leaders adopt a consultative style for making decisions. They engage in different degrees of consultation with individual followers, but the leaders remain the final decision-makers. Leaders do not very often empower followers, and followers have very low power in the organization apart from being able to withdraw from or contribute more of their labor. Compared with classical leadership, under transactional leadership the source of followers’ commitment comes from the rewards, agreements, and expectations negotiated with the leader rather than from their fear of, or respect for, the classical leader. The technical system becomes more regulating, the operations in the organization become more routine and predictable, and the organization is mostly highly controlled by the leaders. Avery (2004) argues that under transactional leadership, the followers’ knowledge base can be somewhat higher than under classical leadership. Compared with classical leaders, transactional leaders require staff somewhat more skilled on specific tasks. In the last three decades, visionary (transformational, charismatic) leadership has received increasing attention (Bass, 1985, 1998; Burns, 1978; Conger and Kanungo, 1987; House, 1977). It added a new dimension to organizational studies, namely the visionary aspect of leadership and the emotional involvement of employees within an organization. The basic notion is that a visionary leader can create an impression that he or she has high competence and a vision to achieve success. Subordinates are expected to respond with enthusiasm and commitment to the leadership objectives, and may be recruited because they share the vision. Bass (1985, 1998) developed a theory of visionary or transformational leadership whereby the leader inspires and activates subordinates to perform beyond normal expectations. According to Avery (2004), visionary leadership has limitations, even with the current literature’s overwhelmingly positive view of it. Nadler and Tuschman (1990) pointed out that the unrealistic expectations followers often place on visionary leaders can create disappointment if things do not work out. Followers can become dependent on visionary leaders, believing that the leader has everything under control. Also, innovation can be inhibited if people become reluctant to disagree with a visionary leader. Avery (2004, p. 39) distinguishes the visionary leadership paradigm from the other three paradigms as follows. First, leaders employ a collaborative style for making decisions. They share problems with their followers and seek consensus before the leaders make the final decision. Visionary leaders empower their followers, giving followers a much higher level of power in the organization than classical and transactional leadership. This is essential because the leader needs the followers’ input and commitment to realize his or her goals. Followers of visionary leadership need sufficient power to work autonomously towards a shared vision. The source of followers’ commitment comes from the influence of the leaders’ charisma and/or the shared vision, the technical system becomes still more complex, operations become more uncertain and unpredictable, and the organization is jointly controlled by the leaders and their followers. Regarding the followers’ knowledge base, visionary leadership requires skilled and knowledgeable workers who are attracted to, and share the leader’s vision, and can contribute to realizing the vision. The fourth paradigm, organic leadership, is relatively new to organizational studies. Recently introduced by Drath (2001) and expanded by Avery (2004), organic leadership is likely to blur the formal distinction between leaders and followers. This paradigm relies on reciprocal actions, where team members work together in whatever roles of authority and power they may have, not based on position power (Hirschhorn, 1997; Raelin, 2003; Rothschild and Whitt, 1986). Employees become interacting partners in determining what makes sense, how to adapt to change, and what is a useful direction. Rather than relying on one leader, organic organizations are likely to have many leaders. Multiple leaders are valuable because as people cope with heterogeneous and dynamic environments, the knowledge and issues become too complicated for only a few leaders to understand (Avery, 2004). Organic leadership allows for people with different degrees of expertise on current issues to emerge and be accepted by the group as leaders. In addition, under organic leadership, there may be no formal leaders and the interaction of all organizational members can act as a form of leadership, held together by a shared vision, values, and a supporting culture. Under this paradigm where an organization has no formal leadership structure, an integrator role may emerge to actively link together the many parts of the organization (Avery, 2004). The emphasis is on emerging leadership rather than on people being appointed to leadership positions. However, Kanter (1989) argued that the downside of organic leadership that advocates autonomy, freedom, discretion and authorization may result in loss of control and greatly increased uncertainty. It is important to recognize that organic leadership is about generating a form of self-control and self-organization, where people have a clear sense of purpose and autonomy within a particular context (Meindl, 1998). This idealized organic leadership paradigm requires differentiating from classical, transactional, and visionary leadership concepts by not relying on formal leaders. Furthermore, the enterprise has to trust in the capacity of its members to solve problems and make decisions in the interests of the organization. This idea clearly relies upon self-leading organizational members (Avery, 2004). According to Avery’s (2004, p. 39) distinguishing characteristics, under organic leadership an organization adopts a mutual agreement style for making decisions. Decisions need not be unanimous but can be based on consensus. The members have a high degree of power as a result of this shared leadership. Accountability and responsibility are shared as well. The source of followers’ commitment is based on the values and visions shared by all the members in the organization; a strong, shared culture; a technical system that is highly complex; operations in the organic organization become more self-organizing and unpredictable; formal control is provided by peer pressure and group dynamics, and a shared culture, vision, and values. Members are self-managing. Organic leadership seems particularly appropriate for professional and knowledge workers in dynamic, chaotic situations. This leadership paradigm relies on attracting and retaining highly trained and knowledgeable staff with self-controlling capabilities.

The Impact Of Trust By Steven Covey - 1436 Words

The Impact of Trust Steven Covey said, â€Å"Trust is the glue of life. It s the most essential ingredient in effective communication. It s the foundational principle that holds all relationships (Covey, 2017).† We unknowingly have trust in many individuals: doctors, firefighters, pilots, and many more. Trust impacts us every day. It impacts our relationships with family, friend, colleagues, and even strangers. We all have different levels of trust in our lives depending on our environment and the people we interact with.

The real question is, â€Å"Who do we trust?† A study by Maxwell J. Mehlman tried to answer this question with a research study. In his study, he found that people tend to be more trusting with people of authority (Mehlman, 2016). This study makes a lot of sense to me. We unknowingly trust people like doctors, teachers, and many others. Bruce Compton said we tend to trust people of authority because of respect (Compton, 2015). Because there is already a visual of the person you have respect with, it is very easy to have trust with that person (Compton, 2015). How Trust Has shaped me I have always had trust issues throughout my whole life. It was always difficult to trust my friends in school.

Corruption Of The Crucible By Arthur Miller Essay - 711 Words

Due to the bias preference of the word of â€Å"God† in the story The Crucible By Arthur Miller, it is greatly implied that many of the casualties such as John and Elizabeth Proctor to name a couple was due to the restricted theology of church and state.

While dancing, they are caught by the local minister, Reverend Parris. These girls are who create most of the controversy, as they lie to get through most circumstances. A specific individual is Abigail Williams, playing the victim for example as she blames Tituba in page 43 saying â€Å"She makes me drink blood!† leading to Tituba to being pulled to the side in page 44 and yelled at â€Å"you will confess yourself or I will take you out and whip you to death† making her give in, in order for him to spare her life. leading to further unjustifiable atrocities. these are only a few of many examples of a broken outdated system which intertwines both church and state, Due to morally bankrupt foundation of the church and state many residents among Salem has remained â€Å"selfish† and took advantage to blame on another in order to save themselves through accusations, while others simply did it for greed.

When might this apply and provide two examples. 2.Compare the bandwidth, distance, interference rating, cost and security of a) twisted pair cable, b) coaxial cable and 3) fibre optic cable. Use current data, give specific details for at least 3 types of cable within each category, these should have different specifications, rather than simply different brands of the same type. Answers: 1.User experience (UX) or human-to-machine cooperation is exceptionally critical for the achievement of IoT. The main focus of IoT UX rule is meeting the fundamental requirements for the utilization of an item or an administration without disturbance or trouble. Overengineering or including excessively insight into items can blowback and be counterproductive. UIs that are frustrating to utilize and ease back to separate significant data can prompt client abandonment. Eg: A toaster exists to make toast. In any case, if we overengineer with a lot of data, switches and alternatives, we make building items that are annoying to the point that our clients won't have any desire to utilize them. Usability is considered as the best prerequisite for any electronic framework. Eg: Apple's iPhone versus rival devices with a similar usefulness. Clients will pay more for simple to utilize devices, and sensors are no exemptions. Consequently, the best UI is "no UI" when sensors are required to work without anyone else's input once they are associated. (Rayes, A. Salam, S., 2017). 2.Twisting Pair Cable - Twisted pair cable can be used for communications in telephone as well as in Ethernet networks. A couple of wires frames a circuit that can transmit information. The sets are twisted to give the protection against crosstalk, the commotion produced by adjoining sets. When there is flow of current in the wire, a small magnetic field is created in the wire. When two wires are put very close to each other, their attractive fields are the correct inverse of each other. Hence, these magnetic field cancel each other. Utilizing cancelation together with twisting wires, link designers can successfully give self-protecting to wire pairs inside the network system. The speed and throughput of twisted pair cables ranges from 10 1000 Mbps. The distance between node and hub can be approximately 100 meters to 328 feet. Exposed cabling can be dangerous, so it is covered with protected material. The protected cable would be resistant to any electrical attractive obstruction cr eated from the power link situated in a similar pathway. Being nominal cost, it is being used to great extent. Eg: Common types of Unshielded Twist Pair (UTP) are: Category1 It is used for telephone communication but not good for transmitting data. Category2 It is used to transmit data with a speed of 4Mbps. Category3 It is used in 10BASE T networks. Its bandwidth is 10Mbps. (Cisco Systems, Inc., 2003). Coaxial Cable - Coaxial cable seems to be like the link used to deliver the TV signals. A strong center copper wire keeps running down the center of the link. Around that strong center copper wire is a layer of protection, and covering that protection is metal thwart, which shields against electromagnetic interference. A last layer of protection covers the plaited wire. The transmission capacity for coaxial cable is 10 Mbps. The most extreme length of cable is 2 feet or less. Its price range from $30 to $50 for 300 meters. Hard Line Coaxial cable It is used for high signal strength applications having radio transmitters. It is mainly preferred for heavy signal transmission due to its thickness. RG-6 Coaxial Cables It is used for high definition signals like cable TV or any other signal. (Thomas, J., 2017). Thick coaxial cables - Thick coaxial link is also known as thicknet. 10Base5 alludes to the details for thick coaxial link that delivers Ethernet signals. The 5 alludes to the greatest fragment length being 500 meters. Thick coaxial link has an additional shielded plastic cover that helps keep dampness far from the inside conductor. This settles on thick coaxial an incredible decision when running longer lengths in a linear bus network. One weakness of thick coaxial is that it doesn't twist effortlessly and is hard to install. (Dr. Winkelman, R., 2013). Fiber Optic Cable - Fiber optic cable deliver communication signals utilizing pulses of light produced by small lasers or light-emanating diodes (LEDs). Fiber links evaluated at 10 Gbps, 40 Gbps and even 100 Gbps are standard. Fiber is less vulnerable to impedance. A customary system link requires exceptional protecting to protect it from electromagnetic obstruction. While this protecting causes, it is not adequate to counteract impedance when many links are hung together in closeness to each other. It cost $6 per feet. (Mitchell, B., 2017). Single Fiber Optic Cable - Single Mode link is a single stand (most applications utilize 2 fibers) of glass fiber with a distance across of 8.3 to 10 microns that has one method of transmission. Single Modem fiber is utilized as a part of numerous applications where information is sent at multi-frequency (WDM Wave-Division-Multiplexing) so just a single link is required. Single-mode fiber gives a higher distance than multimode, yet it additionally costs more. Multi-Mode Cable - Multi-Mode link has small diameter with a typical diameter in the 50-to-100 micron for the light carry component (in the US the most widely recognized size is 62.5um). Multimode fiber gives you high transfer speed of 10 to 100MBS - Gigabit to 275m to 2km over medium distance. Light waves are scattered into various ways, or modes, as they go through the link normally 850 or 1300nm. Multimode fiber diameter across are 50, 62.5, and 100 micrometers. (MacChesney, J., n.d). Step Index - They are generally cheap as well as they have the greatest scope of center diameter across: fundamentally from 50 m up to 2 mm. The material might be plastic, fluid or glass. (Ovejabiennera, 2009). The three common ways to obtain information from IoT devices are sensors, RFID and Video tracking. Compare the three technologies by addressing the advantages, disadvantages, key requirements for the things. Provide two applications of each. Sensors RFID Video Tracking Advantages It provides more accurate reading. These devices constantly monitor the details available. These devices do not require humans for its operation. Sensors immediately respond to the information. RFID tag ought not be in LOS to influence the framework to work. As compared to barcodes, labels can store more data. In addition it takes after reader's commands. It gives area to the peruser with the ID. RFID labels are utilized for tracking baggage and in addition for checking wellbeing history of patients. RFID innovation is flexible in nature and henceforth small as well as bigger RFID gadgets are accessible according to application. Its execution does not rely upon nature of the protest recognition process. The principle idea of this tracker incorporates estimation, multi-highlights comparability measures and direction sifting. It helps to detect the crime. Disadvantages In case of any fault in the device, they provide wrong result. Eg: In reverse parking of car, when sensor become dirty, they dont find any type of obstacle. Their operating range is very limited. (ICT Lounge, n.d). Dynamic RFID is exorbitant because of utilization of batteries. The main concern is privacy with the utilization of RFID on items as it can be effortlessly captured. RFID gadgets should be modified which requires enough time. Use of RFID innovation at inventory and for other such applications prompt loss of occupations for incompetent worker. (RF Wireless tutorials, n.d). The main issue is privacy. The tracking system are expensive. These devices are vulnerable. Key Requirements An essential detecting component; Excitation control; Intensification (variable gain); Analog filtering; Information transformation; Cost; Computerized data handling; Computerized data communication; and Power supply. (National academy of science, 2017). Application high frequency Quality Playback Export Recording (Library archives, n.d). Applications IR Sensors are used in TV remotes. Passive Infrared sensors are used automatic doors. Hospitals use RFID to track their patients. It can be used in reducing medicinal error for patients. Traffic monitoring Retail security for the staff Industrial monitoring Discuss the issues associated with security and privacy in the context of the Internet of Things. Security Risks 1. It enables unauthorized access and abuse of individual data; (2) It encourages assaults on different frameworks; and (3) It creates threat to the individual safety. Privacy Concerns - Some of the privacy risks include the immediate collection of sensitive individual data, for example, exact geolocation, financial accounting data, or wellbeing data hazards as of now introduced by customary Internet and versatile business. Others emerge from the accumulation of individual data, propensities, areas, and physical conditions over time, which may permit an element that has not gathered sensitive data to derive it. (FTC staff report, 2015). An IoT water level monitoring application requires updates from a sensor periodically, using the command/response paradigm. The application triggers a request every 1 s. The round-trip propagation delay between the application and the sensor is 12 ms. On average the sensor consumes 3 ms to process each request. The application consumes 2 ms to send or receive any message. If the application blocks on every request to the sensor, how much of its time budget can be saved by redesigning the application to use the publish/subscribe communication model in lieu of the command/response approach? If the application blocks on every request to the sensor, the time budget which can be saved by redesigning the application can be 17ms for each request. Describe Nielson's Law. How does it relate to Moore's Law? What are the implications for the Internet of Thing? It states that the high end user connection speed increases with 50% each year. The dots in the graph demonstrate the different speeds with which we have associated with the internet, from an early acoustic 300 bps modem in 1984 to an ISDN line. It is astonishing how intently the exact information fits the exponential development curve for the half annualized development expressed by Nielsen's law. Nielsen's law is like the more established Moore's law. By looking at the two laws represents that transmission capacity develops slower than system power. Moore's law says that systems are double in abilities like 18 months, which compares to around 60% yearly development Implications - Transfer speed is one of the two most critical components in processing, since computational rates are more than for non-designing undertakings. Website composition needs to take into account the majority. No one but once in a while a site can be effective in the event that it is gone for the most developed 10% of clients.

The aim of the first portion of the survey was to happen the best ratio of ink utilizing C from used batteries and wood coal as pigments. The ink was evaluated on the footing of how much pigment is suspended in the mixture and their shelf life. The 2nd portion was aimed at the production of C paper. The best sorts of ink were tested on two mediums. voucher bond and onion tegument. They were besides tested for efficiency in footings of the figure of coatings needed. The C paper was evaluated on the footing of lucidity. spruceness of the print and general acceptableness. The concluding sample made usage of two coatings of the ink mixture utilizing C black. with voucher bond as the medium. The pigment ( carbon black ) to vehicle ( glycerin ) ratio of 1 g: 6 milliliter and 1 g: 7 milliliter was used utilizing C black as pigment with glycerin as vehicle. Although the commercial bond paper has better quality. We will write a custom essay sample on Investigatory Project Essay Sample or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page since it uses more technologically advanced methods. the usage of the experimental C paper was acceptable. INTRODUCTION Carbon paper has many utilizations. It has a high demand in schools. offices and other establishments. The ink used in the production of commercial C paper is expensive due to its high production costs. Because of its high cost and increasing demand. there arises a demand for a cheaper replacement. The survey besides aims to assist cut down the jobs in disposing used batteries by be printed ; and ( 5 ) nature of pigment. Glycerol is syrupy and is easy absorbed by paper and. therefore. makes it a good vehicle. Burned wood is a good beginning of wood coal. Batteries have black atoms called black mix. which is chiefly composed of C black. acetylene black doing good usage of them. REVIEW OF RELATED LITERATURE Ink is a mixture of vehicle ( liquid constituent and dissolver ) . pigment ( colourising affair ) and other substances added to leave particular qualities such as a binder. Carbon is normally used as pigment because of its low oil soaking up. easiness of scattering and low scratch to plate ware. Carbon is chemically inert and infusible at atmospheric force per unit area. which makes it an indispensable portion in the black pigment used in books. magazines. newspapers. C paper. etc. Two good beginnings of pigments that are carbonous in nature are wood coal and the black mix found in used batteries. These beginnings are much cheaper than the usual black pigments such as C black in black lead and carbon black. In order for the pigment to thoroughly dissolve with the vehicle. the pigment must be pulverized to really all right atoms. The pigment affects the belongingss of ink such as rubric and opacity. The vehicle on the other manus must accommodate the undermentioned conditions: ( 1 ) the printing system used ; ( 2 ) category and velocity ; ( 3 ) drying imperativeness required ; ( 4 ) category and texture of the surface to Coconut oil and dextrin were tested for their possible as ink binders. Harmonizing to the consequences. coconut oil was a better binder than dextrin. METHODOLOGY Black mix was obtained by opening the protective lodging of a drycell battery and exposing its C content. Then. the black mix was removed and land into really all right atoms utilizing a howitzer and stamp. Afterwards. it was sieved through a all right screen to obtain the finest consistence. On the other manus. wood coal was besides finely pulverized. It was so assorted with H2O and placed in a one-litre beaker. The mixture was allowed to settle for two yearss inside the covered and manganese dioxide. The Cs obtained from both beginnings are carbonous in nature. doing them good beginnings of black pigm ent. After two yearss. the wood coal pigments were heated to let vaporization of extra wet. In fixing the ink. the wood coal and C black pigments were combined with glycerin ( vehicle ) and coconut oil ( binder ) in different proportions runing from 1 g: 10 milliliter: 1 milliliter ( pigment: vehicle: binder ratio ) to 2 g: 14 milliliter: 2 milliliter. The solution was exhaustively assorted utilizing a stirring rod until wholly dispersed. Finally. the mixture was heated for five ( 5 ) proceedingss under medium heat and was allowed to chill down before rating. The best ratio utilizing each pigment was so compared to find which ink is more suited for C paper production. The samples were RESULTS AND DISCUSSIONS The onion paper appeared to be excessively thin to be used as a medium because it has the inclination to be torn even after one coating. The voucher bond was proven to be the better option. It takes five ( 5 ) proceedingss for a solution with a ratio of 1 gm ( pigment ) : 6 milliliter ( vehicle ) to dry up. The solution with a ratio of 1g: 7 milliliters took six ( 6 ) proceedingss to dry. The sample which used two coatings was proven to be most practical. SUMMARY AND CONCLUSION The experimental C paper is acceptable plenty to be used as a replacement for commercial C paper. The experiment was able to turn out that the pigment obtained from battery C is better and cheaper than those from wood coal. Evaluated for smoothness. consistence. and soaking up. The ink samples. runing from one to four coatings. were applied on the onion tegument and voucher bond. The different C documents were tested and observed for their drying clip. soundness and lucidity of print. After finding the best sample. a study was conducted on 20 pupils utilizing the experimental C paper and a commercial C paper. Research workers: Jonas Don Castelo Lloyd Gonzales Marcelino Quito.
