The Role of Performance Appraisal to Motivate Employee

How to Use Performance Appraisals to Motivate Employees By Ken Lloyd from Performance Appraisals and Phrases For Dummies Motivation is the process that energizes employees and propels them to pursue their goals. Well-designed and well-executed performance appraisals have a strong motivational impact. Appraisals have the power to motivate employees because they provide a number of interconnected benefits: They demonstrate the need for improvement. If employees don’t have a clear understanding of how they’ve been performing, they can’t be motivated to make any improvements. They meet higher-level psychological needs.Researchers continue to find that recognition is one of the most powerful forms of motivation for large numbers of employees. Although you can find numerous possible sources of recognition on the job, performance appraisals are an opportunity for employees to receive formal, significant, and enduring recognition from their manager. They build a sense of personal value. When managers take the time and effort to carefully review, analyze, document, and discuss performance with employees, the underlying message to the employees is that they’re important and valuable, and this alone is quite rewarding, whether the feedback is positive or not.They enhance personal development. Performance evaluations are motivational for employees who are looking to enhance their personal learning, growth, and development. Appraisals are a highly valuable source of information, insights, and tools necessary for such progress. Performance appraisals are similarly motivational for employees whose needs are centered on achievement, goal attainment, and sensing personal effectiveness, respect, and trust. They turn employees around. When employees are performing poorly, performance appraisals can provide the wakeup call that they need to get refocused and reenergized.With performance appraisal, however, the purpose of the session is not strictly disc iplinary, so the employee is more likely to walk in with a more receptive and open mind. As a result, your comments regarding an employee’s questionable performance have an excellent chance of being heard and generating action as a result. They increase satisfaction. When performance appraisals meet the employees’ needs in such areas as gaining recognition, sensing achievement and competence, experiencing growth, and meeting objectives, they’re also contributing to the employees’ job satisfaction, and this is one of the most important elements at work today.When employees are satisfied, some of the most visible indicators are reduced turnover, absenteeism, and tardiness. On the flip side, when employees are subjected to a shoddy or even nonexistent performance appraisal system, the opportunities to fulfill these higher-level employee needs are substantially reduced.

Muse Terpsichore Essays

Muse Terpsichore Essays Muse Terpsichore Paper Muse Terpsichore Paper The other woman in Rhesos is the title characters mother, the Muse Terpsichore. She appears above the stage (deus ex machina) cradling her sons slain body and is beside herself with grief for her loss and blames Athene of betrayal as she and the other Muses and Phoebus trained Mousaios who was associated with Athene is some way.In Rhesos the female characters are not developed as fully as the male characters and the above written word probably add up to more words then both spoke in the play. However, the point is proved once again from this play that Euripides did not just create hateful women in some misogynistic way.In the Children of Heracles, Euripides creates a minor form of Polyxena in the character of the Maiden one of Heracles daughters. In other texts she is referred to as Macaria, hereafter know as the latter. Macaria dies for the good of others. She dies as a voluntary virginal sacrifice. If she hadnt the Athenians will lose a battle. Heracles family have come to Athens to seek sanctuary from the tyrannical Eurytheus that despite the fact that Heracles is dead at this point in time is still persecuting Heracles family. Demophon was the King of Athens at the time. She is another noble female character that Euripides has created.The other female character in The Children of Heracles is Heracles mother Alcmene. She is vengeful and wants the Athenians to kill Eurytheus. As a play, The Children of Heracles is not at all memorable and the two female characters aforementioned are equally forgettable with the parts they play in the action of the play. Macarias self sacrifice is not developed enough to have even a touch of the effect that Polyxenas had and Alcmenes character has too many weak lines for such a strong personality in all other texts she is mentioned. Still, Euripides handles their characters in the play very respectfully.In conclusion, along with the positively vicious characters such as Medea and Phaedra, Euripides has created noble and wonderful female characters such as Polyxena and Megara. He has also created complicated female characters such as Hecabe and Electra and memorable female characters such as Alcestis and Phaedras nurse. Euripides skills as a playwright are near perfect for getting an audience reaction whether its tears, shock, hatred or love for a character. He can never be described as a misogynist but should be complimented on the fact that he has been accused as one. For a playwright to create such characters that cause their audience to either love or hate the playwrights characters is positive accomplishment enough.

Detection and Prevention of Wireless Intrusion

Detection and Prevention of Wireless Intrusion Abstract This research shows elements of wireless intrusion detection and intrusion prevention. It shows the main areas of wireless intrusion and detection together with advantages and challenges of using a wireless intrusion and detection systems. Overall, the research concludes that a wireless IDS offers many advantages than challenges it may present to users.Advertising We will write a custom research paper sample on Detection and Prevention of Wireless Intrusion specifically for you for only $16.05 $11/page Learn More Wireless local area networks (WLANs) have many threats, which could have significant impacts on the network. Threats to WLAN technologies include â€Å"wrongly configured wireless access points (WAPs), Denial of Services (DoS) and possible system hijacking† (Max, 2009, p. 3). Wireless networks are also prone to common attacks like TCP/IP and 802.11 threats. TCP/IP threats also are common in networked technologies. WLANs must incorpor ate security techniques that can detect and defend against potential threats. These are intrusion detection system (IDS) solutions. Introduction WLANs have the same IDS as a Network Intrusion Detection System (NIDS) because they can also evaluate network traffic for potential security threats. However, IDS can evaluate specific areas, which only relate to WLAN. These include WAPs, rogue WAPs, and offsite users. The growth in wireless technologies has allowed networks to support wireless devices at different sections of the network typology. This suggests that WLAN IDS have critical roles to play in network securities.  WLANs may have unconnected wireless sensors to analyze traffic. The physical location of a sensor is critical for effective analysis of network traffic. The location normally influences what a network sensor can detect and monitor. Network sensors should have the ability to monitor all gadgets that can gain access to the network. Some wireless networks may have more than a single sensor. These sensors go beyond the normal scope of network operations. In most cases, the WLAN may have a single channel, but it also has options of running on several channels. Thus, WLAN sensor may effectively serve a single channel. However, regular changes can ensure that WLAN sensors can analyze several channels. IDS has many parts, such as consoles, databases, and system sensors. Users can run the system on either a centralized or decentralized platform.Advertising Looking for research paper on it? Let's see if we can help you! Get your first paper with 15% OFF Learn More Figure 1: WLAN IDS Wireless Threats Wireless local area networks are susceptible to a number of threats. The normal 802.11 encryption has become susceptible to attacks (Max, 2009, p. 7). In addition, the Wired Equivalent Privacy (WEP) may not withstand constant brute force attacks. In other words, encryption alone cannot protect the network because the intruder can sti ll attack and decrypt sensitive information in wireless networks. Attackers also rely on rogue WAP to attack WLANs and gain access to sensitive information in the system (Vladimirov, Gavrilenko Mikhailovsky, 2004, p. 435). Attackers normally construct rogue WAPs in a similar manner as real WAPs. Most users have the tendency of connecting to any WAP with appropriate signals. At this point, users can accidentally connect to a rogue WAP. This provides an opportunity for the attacker to monitor all forms data transmission across the connected devices. At the same time, some users may also â€Å"introduce rogue WAPs in the wireless network† (Low, 2005, p. 89). This happens because of low costs and ease of connectivity in the WLAN systems. Users can install other access points in the network and render other security features ineffective. This makes the network an easy target for attackers (Low, 2005, p. 89). Users must consider the deployment of a wireless IDS security solution t o protect the network from such vulnerabilities. IDS solutions can protect the network from installed rogue WAPs. DoS may also affect networks that rely on 802.11. Hackers can derail such networks. Physical objects may also affect communication systems across wireless networks. These may include tall buildings, trees, and even rain. Other physical objects that have signal systems may also affect 802.11 networks. There are attackers who use fake requests to congest the system in order to force the system reboot.Advertising We will write a custom research paper sample on Detection and Prevention of Wireless Intrusion specifically for you for only $16.05 $11/page Learn More At the same time, such attackers can also make repeated requests as a way of denying services to authentic users.  Other security threats include poorly secured network devices, man in the middle, and unauthorized systems on the network. WLAN IDS sensors should have the ability to detect these threats (Kent Mell, 2006, p. 87). There are other forms of WLAN threats, including new ones. These threats have critical repercussions on networks they attack. WLAN that lacks any form of threat intrusion detection and prevention may find it difficult to notice threats on the network. A lack of awareness about threats creates vulnerable networks for attackers. Thus, organizations should have effective ways of detecting and preventing intrusion in the network. Intrusion detection Intrusion detection systems (IDSs) have the ability to recognize any unusual usages and access on the network (Base Mell, 2001, p. 78). They can analyze data in the system and detect any anomalies (Caswell, Beale and Baker, 2007, p. 411). IDSs have the capacity to recognize intrusions and abnormal usages in the network system. The new IDSs for wireless devices can sense, monitor, collect, and analyze data in order to locate known attacks, reveal abnormal network usages, and show misuse within the net work (Yang, Xie Sun, 2004, pp. 553-556). IDSs collect information and generate corresponding alerts based on the type of intrusion detected.  A wireless IDS may be the same as networked IDS. However, WLAN IDS has specific security features for wireless networks only. WLAN intrusion detection Organizations can develop their own wireless IDSs or obtain them from vendors. While wireless IDS technologies are new, the available ones are effective security solutions. Moreover, they also have extensive security features. The most common IDS solutions include RogueWatch, Airdefense, and Airdefense Guard (Kent Warnock, 2004, p. 8). There are also Internet Security Systems and other system scanners.  Users can develop their own wireless IDS by using free software from Open Source. Configuration There two types of a wireless IDS configuration. These are centralized and decentralized configurations. A centralized wireless IDS uses several independent sensors on the network to gather infor mation. The sensors collect information and transfer them to a central place for analysis and storage. On the other hand, a decentralized intrusion system has different gadgets for data collection, analysis, and reporting. This type of intrusion detection is appropriate for small networks because it is expensive to run and maintain (Rhodes-Ousley, Bragg and Strassberg, 2003, p. 263). Moreover, decentralized systems may require much time from the organization.Advertising Looking for research paper on it? Let's see if we can help you! Get your first paper with 15% OFF Learn More WLANs may cover a large area. This could weaken the signal strengths. Therefore, it is appropriate to install several WAP to provide extra strength for the network. However, one should deploy a sensor in every access point with WAP. Several sensors in every access point can easily detect intrusion in the network. Moreover, the sensor can identify sources of threats within a given geography. Physical Location The wireless detection systems should be able to locate physical locations of attackers. Most hackers attack the network in locations close access points and WAPs in order to reduce the time for attack. Organizations should deploy people physically to respond to attacks in a timely manner. Attacks on networked systems could occur several miles away. However, in a wireless system, the attacker could even be in the same location. Effective wireless IDS can assist in providing a physical location in which the hacker could be located. Information obtained from the 802.11 and the loc ation of the WAP can â€Å"aid in quick detection of the attacker’s actual location† (Calabrese, 2003, p. 29). In some cases, directional antennae aid in tracking the location of the attacker by tracing the source of the attacker’s signals. The IDS and other scanning systems are effective for this role. The physical response team can rely on these other teams to intercept the attacker. Policy enforcement Organizations can â€Å"use wireless IDSs to enforce their policies† (Calabrese, 2003, p. 32). WLANs may have many security challenges. However, there are solutions for these issues. Effective organizational policy can ensure that wireless networks remain secure. Enforcing organizational policies on wireless devices is an effective way of ensuring wireless network security. Organizations should ensure that all its data are encrypted before transfers (Calabrese, 2003, p. 34). The wireless IDS can analyze the system and detect any attempts to transfers data without encryption. Effective configuration of WAPs can ensure that IDSs have the ability to easily identify rogue WAPs as soon as they attempt to gain access to the network. Detection of a rogue WAP and enforcement of organizational policies on wireless communications can enhance the level of wireless network security. Policies on automated systems can eliminate the use of human to monitor possible rogue WAPs on the network. This can enhance effective use of resources in an organization. Detecting threats A wireless IDS is effective in identification of threats in the network. It can help in identifying rogue WAPs and any non-encrypted data during transfer in 802.11. Moreover, wireless IDSs can also detect attackers’ location and monitor the system for known attacks.  Hackers rely on scanning devices and software as tools for detecting possible points of attack on the network. Scanning tools like Kismet have been effective in identifying weak areas within the network. Att ackers target such points on the WAP and apply GPS (Global Positioning System) to locate the most vulnerable geographical spot on the network. Scanning software and other detection tools are common, and organizations can use wireless IDS to identify such software on the network. This can help in reducing vulnerability of the network from external analysis by hackers (Hsieh, Lo, Lee and Huang, 2004, pp. 581-586).  Reliable wireless IDS can detect some DoS threats on the network (Trost, 2010, p. 53). DoS attacks are the most common attacks on wireless networks. Physical objects may cause conflicts in frequencies. Attackers may exploit such opportunities to deny users services from the network. A wireless IDS has the ability to detect these forms of attacks, which aim to flood the network with requests or generate unauthorized requests.  There are also other threats that a wireless IDS can detect on the network. For instance, many attackers may masquerade as authentic wireless devi ce or a client. In such cases, a wireless IDS can detect threats from MAC address spoofing. A wireless IDS uses a series analysis to â€Å"detect the presence of MAC address spoofing on the network† (Trost, 2010, p. 76). It can only detect ad-hoc networks. This is a configuration issue, which provide opportunities for attackers to use wireless devices and gain access to the network.  A wireless IDS can also identify some uncommon or new forms threats by using users defined requirements. In this context, it provides flexibility that other general IDSs may not have. Hence, users can use wireless IDSs to define their security features for locating unique threats. It is an effective method of building strong security features for WLAN. People who may know that the network relies on IDS features may not be interested in attacking the system. This is a way of deterring threats on the network. Wireless IDS issues Clearly, wireless IDS offers numerous advantages to users in detecti ng and preventing threats to the network. However, organizations should consider some aspects of wireless IDS, which may affect the effectiveness of their systems. Wireless intrusion detection is a field that is still evolving. Thus, it is important for users to be careful when deploying new systems with no proven track records on their networks. New technologies may present new challenges or bugs to the network. Such challenges could be new forms of vulnerabilities, which would render the network unsafe and prone to attacks. One must also recognize that wireless technologies have evolved rapidly in the recent past. Hence, organizations may find it difficult and costly to keep pace with new discoveries in technologies. Maintaining a wireless security system could be expensive, especially when they come from vendors. Organizations have opportunities of developing their own IDS solutions. However, this could present new challenges like qualified human capital and additional resources for such projects. Costs of monitoring wireless IDS solutions normally increase as the size of the network also increases. A large network may require several sensors or other monitoring devices, which increase costs of developing and maintaining a wireless IDS solution. Effectiveness of a wireless IDS may depend on the expertise of the user and the extent of responses to detect threats (Mandia, Prosise Pepe, 2003, pp. 12-32). This process may require extensive experiences, resources, and expertise for effective response to threats. Responses must be both physical and logical in order to get hackers. Costs of a wireless IDS is prohibitive for small firms. In addition, they may not have the required human resources to implement and maintain such systems. Overall, a wireless IDS provides effective security solutions against intrusions. Conclusion Wireless intrusion detection and intrusion prevention solutions provide protection against potential attacks on the network. Implementing a nd maintaining a wireless IDS may have some drawbacks. Nevertheless, it offers effective network security against intrusions. It has abilities to detect different types of 802.11 threats, DoS, and analyze the system. Organizations with wireless policies and can enhance the effectiveness of wireless IDSs significantly. IDS does not offer total security solutions to networks. Instead, WLANs need other forms of security systems. A wireless IDS reinforces security features that already exist in a network. Users must recognize that technologies have focused on improving the use of wireless system. These changes bring about new complexities and security challenges. Thus, systems for detecting and reporting new threats can improve the effectiveness of a wireless network. References Base, R., Mell, P. (2001). Intrusion Detection Systems.

How to Use the Conditional Tense in German

How to Use the Conditional Tense in German The conditional tense in German is established through the subjunctive II  (past). But that is not the only way. As important as it is to learn the subjunctive II for such purposes, there are sometimes other ways to form a conditional statement, depending on your intent. The following is a listing of a few examples. Introducing a Condition With the Preposition Bei Bei schà ¶nem Wetter, gehen wir schwimmen.(When the weather is nice, we’ll go swimming.)Remember that the preposition bei is always followed by the dative. If you would use the subjunctive, the sentence would read as follows: Wenn es schà ¶nes Wetter sein sollte, dann gehen wir schwimmen. Using Wenn Use wenn plus the present tense if the condition is possible. Wenn du mà ¼de bist, leg dich hin.(If you are tired, lie down.) Wenn du Hunger hast, nimm dir ein Stà ¼ck Kuchen.(If you are hungry, you can have a piece of cake.) Use wenn plus the subjunctive II if the sentence indicates a hypothesis not realized. Wenn ich jung wre, wà ¼rde ich mir diese Schuhe kaufen.If I were young, then I would buy these shoes. Wenn wir reich wren, wà ¼rden wir auf eine Weltreise gehen.(If we were rich, we would go on a world trip.) Use wenn plus the subjunctive II if the sentence indicates a hypothesis that was not realized in the past. Wenn er studiert htte, wà ¼rde er gute Noten bekommen haben.(If he had studied, he would have gotten good marks.) Wenn er seine Medizin genommen htte, wà ¼rde er jetzt gesund sein.(If he had taken his medicine, he would be healthy now.) Using Falls/im Falle When something is possible. Falls du zum Museum hingehst, vergiss nicht dein Mitgliedsausweis.(In case you go to the museum, don’t forget your membership card.) Im Falle, dass wir spt sind, will ich mir eine Ausrede denken.(In case that we are late, I want to think of an excuse.) Using Es Sei Denn, Dass (Unless)/Vorausgesetzt, Dass Geh nicht im Keller, es sei denn, dass du vorher gefragst hast.(Don’t go in the basement, unless you’ve asked beforehand.) Guck nicht im Schrank, es sei denn du willst wissen was du fà ¼r deinen Geburtstag bekommen wirst.(Don’t look in the closet, unless you want to find out what you will be getting for your birthday.) Ich komme mit, vorausgesetzt, dass deine Eltern einverstanden sind.(Im coming, only unless your parents agree.) Adverbs Sonst (Else) or Andernfalls (Otherwise) These adverbs make reference to the past that would have influenced the past, that the situation occurred. Ich bin froh, dass du mitgekommen bist, sonst htte ich mich sehr gelangweilt haben.(I am happy that you came along, or else I would have been so bored.) Gute Sache, dass er die Suppe nicht gegessen hat, andernfalls wà ¼rde er auch krank gewesen sein.(Good thing, he didn’t eat the soup, otherwise he’d be sick too.)

Write a researched business report about the credit suisse internship Essay

Write a researched business report about the credit suisse internship and analyse a candidates suitability for an internship role in that given company - Essay Example One is able to gain work experience and a set of skills that can quickly and easily be transferred to their peers. This would be particularly helpful when searching for employment after completion of studies. The individual also networks with the experienced professionals and has a chance to work with them later on in his career. The internship opportunities also show them their strengths and weaknesses. Once able to identify them he can then decide to focus on where his talents best lie. This, in turn, helps them to gain confidence in their abilities. Before anyone can land the important role of an intern, several factors must be considered. The following research was conducted to show the suitability of an individual for an internship role in a company such as Credit Suisse. The research itself was conducted majorly online. Journals, articles and even the company’s website were heavily used as data extracts. A report by Albert Laurence entitled ‘The Belbin Report’ was also used as it gives in depth analysis to the factors as well. These were in reliance due to the complicated nature of the report and the inability to contact the company in question; Credit Suisse. The aforementioned company has branches all over the world. Gaining an internship position with such a prestigious firm would catapult one to a different platform. He would be streets ahead of his peers in terms of experience and skills gained. Income is also a major possibility given the firm’s strong financial position. His confidence in his abilities would also receive a major boost. The firm’s internship programs are four; analyst, diversity, quantitative and associate programs. In the analyst program, an individual gets offered a chance to work within the financial services industry. Since the Credit Suisse is a global enterprise, one may be assured of interacting within people of diverse and backgrounds. The diversity program makes this happen. Through the quantitative

Earthquake Paper Essay Example | Topics and Well Written Essays - 500 words

Earthquake Paper - Essay Example The earthquake was marked by a thrust-faulting focal mechanism which saw the subduction of the Nazca plate underneath the South American Tectonic Plates (USGS, 2010). For Haiti, the earthquake occurred at the northern boundary of the Caribbean tectonic plate which shifts eastwards per year in relation to the North American Plate (Amos, 2010). The depth of focus for the Japan earthquake was 32 kilometers, for the Haiti earthquake, it was 13 kilometers, and for the Chile earthquake, it was 35 kilometers. The tsunami which followed the Japan earthquake caused a greater damage than the earthquake itself. The earthquake caused a 5-8 meter upthrust in a 180-km seabed offshore from the coast of Tohoku which then caused the tsunami which devastated Japan’s northern islands and the Pacific coastline (CNN Wire Staff, 2011). The tsunami extended across the Pacific with warnings issued to coastal towns. Chile, which was the furthest area from Japan still felt tsunami waves 2 meters high. In the Omoe peninsula, Miyako city, and the Iwate prefecture, tsunami waves were also felt (Yomiuri Shimbun, 2011). The height of the tsunamis hitting Japan ranged from as low as three meters to as high as 13 meters, covering about 560 square kilometers of Japan, and the waves were seen an hour after the earthquake hit first in Sendai airport and in the rest of the northern coast of Japan following (CNN Wire Staff, 2011). A four meter tsunami would also hit the Iwate prefecture and the Wakabayashi Ward in Sendai. A major part of Kuji and Ofunato were destroyed and in Rikuzentakata, tsunami waves were reported at about three stories high (CNN Wire Staff). Damages in the cities of Kamaishi, Miyako, Yamada, Namie, Soma, Minamisoma, Shichigahama, among others were also reported. The most severe impact of the tsunami was felt along the coastline stretching from Erimo to Oarai with bridges washed out and a wide swath of general destruction (CNN

Business law - Contract problems, FIRAC case, and short summary Assignment

Business law - Contract problems, FIRAC case, and short summary - Assignment Example to be bound by the agreement, statute of fraud covers contracts of sale of goods for a cost of at least $ 500 and requires such contracts to be in writing (Clarkson, et al, p. 234, 303). Hodge entered into a contract to work for Evans on the prime condition that the contract would be permanent. His condition was accepted but he was fired within a year. Hodge has sued for a breach of contract while Evans argues that the oral contract is unenforceable. Watkins and Iams entered into an annually renewable contract in which Watkins was, based on a promise, to be the sole distributer of Iams’ products in Michigan. The renewed contract in 1993 however reserved the company’s right to appoint any other distributor in Michigan. Iams then notified Watkins that its contract would not be renewed and contracted another company. Watkins has since sued for breach of contract, fraud, and promissory ‘estoppel’. A contract that either does not involve land, is enforceable within a year, is not a contract of guarantee, is not a promise that involves â€Å"consideration of marriage† and is not for sale of goods worth at least $ 500 dollars does not necessarily have to be in writing (Clarkson, et al., p. 304). Promissory estoppels also creates liability on promises relied upon in contracts (Clarkson, et al, p. 259). Dyer purchased a car with written provisions that no taxes were included in the price. While the contract restricted the agreement to its written terms, the salesperson assured her that sales tax was already paid. She has realized otherwise and has sued for breach. The parole evidence rule provides that oral agreement that precedes or is made alongside a written contract, in which the parties intended to be fully bound by the written contract, is inadmissible. The rule however has exceptions that include â€Å"contract subsequently modified, voidable or void contracts, contracts containing ambiguous terms, and incomplete contracts† among others (Clarkson, et al,
