(business)Minimum Wage - Essay Example Peter Jones in Rights contrasted the difference between natural and human rights1. The concept of natural rights is tied up in the idea where the citizens gave up to the governing body for the good of law and order and in return the governments protected and upheld within the law, i.e., Constitutions. Therefore the argument of natural rights has now become so diluted that it is no longer an effective model. Human Rights as theory admits from the outset they are intangible and not from nature, therefore one cannot empirically observe or measure them, as Margaret MacDonald2 criticized the argument from nature. Human rights, as described by Jones, are prescribed by the fact of being human and part of humanity3. It picks up on the egalitarian theory of equality, whereby human beings are equal and therefore are afforded these basic rights. The arguments for these rights come from arguments, such as self-evidence, human worth and moral worth. The basis of the core rights theorists is the work of Immanuel Kant. ... How does Kant argue that this is an all-encompassing ethic outside of societal conventions, without the aid of a divine being Kant argues that it is the individual's ability to reason and autonomous will that is the basis of his a priori argument. Shestack5 describes the basis of Kant's argument as; 'rights then flow from the autonomy of the individual in choosing his and her ends, consistent with a similar freedom for all... In short, Kant's imperative is that the central focus of morality is 'personhood', namely the capacity to take responsibility as a free and rational agent for one's system of ends'.6 This ethic was one of the most influential arguments for universal human rights, in response to Nazism, eugenics and ethnic cleansing, which can be illustrated in the Universal Declaration of Human Rights with words such as inherent, inalienable and equality applied to rights and the basis of these rights are the foundation of freedom, justice and peace in world. Kant's theory is th e basis of the core theorists and has been very influential in the drafting of the 20th Century human rights treaties and legislation. However how do we measure what should be included in these universal rights The answer to this question is at the heart of this discussion for the international treaties and human rights legislation does not seem to be meeting the needs to fulfil Kant's ethic as Evans argued modern human rights law is too legalistic. This is a core rights theory, which purports these rights transcend statehood therefore automatically requiring the state to extend these rights to all individuals and arguably future generations. Rawl's, on the other hand, in his thesis for engendering human rights states that justice7 is the prime basis of all

Mental Health and Mental Disorders - Essay Example He worked out Rational Emotive Behavior Therapy. This author stated that emotions derive from "an interaction between events in the environment and beliefs and expectations which we have". (qtd in Clark, p. 130) Sometimes these beliefs are so powerful that they affect person's emotional conditional. The purpose of emotive behaviour therapy is to make these emotions less powerful and not badly influence person's emotional condition. (Clark). According to the concepts of cognitive theory, specialists counseling in mental disorders, should focus on mental condition of the client and investigate his identity, rather than treat his physical body with the help of medicines that may have side effects. Another famous author who worked in the field of cognitive therapy was Aaron Beck. He worked out a special methodology and strategies to treat depression and anxiety that were based upon the conceptions of cognitive theory. Clients are to perform a dialogue within his inner world to define the patterns that are to be changed to improve client's condition. Treatment strategies worked by Beck help a client to find out depressive beliefs and change his way of thinking. The commentators describe the essence of Beck's approach as following: "According to Beck and Emery, the way we process information is governed by structures called schemata. These schemata are made up of rules for explaining incoming information, and for retrieving what we have already learned. They are capable of exerting powerful effects on how we experience and relate to the world. For example, the schemata of a person with a social phobia cause them to become anxious and avoidant by explaining incoming information a nd memories in terms of social threat. Treatment consists of correcting faulty or illogical thinking by repeatedly confronting cognitive schemata with discrepant information from role-playing and homework assignments." (Abela, p.117) Modern medicine includes treating depression and anxiety with psychotherapy or medications, or combining both these treatments. The experiments and researches show that a combination of these two methods is mostly effective, especially because antidepressants rarely result in dependence. Companies that produce medicine encourage doctors to prefer medical treatment to psychotherapy, but there are cases in which referring to a specialist in psychotherapy is necessary. In case the person takes antidepressants and this brings no results, a visit to professional in mental health may be more effective. (Clark) Cognitive theory and therapy based upon it provide for a theoretical basis allowing specialists better understand the reasons for anxiety and depression to appear, to treat them effectively. This theory is regarded as effective even in comparison with other popular theories. To better understand the impact of cognitive theory into modern psychotherapy it is necessary to observe its perspective on mental illnesses and anxiety in particular. According to the cognitive theory, the reasons for depression, anxiety and worries appear due to several reasons: Sometimes it is enough just to see a model of behavior to take it over, when a person expresses intense fears or nervous condition. Sensitive people often answer such behaviour the same way. Sometimes a person inadequately estimates the situation and interactions with people

Human Recourse Management Amounts to Little More Than a Simple Essay

Human Recourse Management Amounts to Little More Than a Simple Reworking of the Human Relations School of Management - Essay Example This essay stresses that there are several factors which have there impact on the growth of the HRM as a field. The main factors are economy and society. During the period of agrarian economy the social structure and economy was very simple. It developed into a complex system during industrial revolution. The social set up changed. There was more emphasis on the productivity. Manufacturing industry contribution to economy decreased in subsequent years and Service Industry experienced growth. The importance of human increased due to the fact that human is important factor in the production and consumption of services. Human resources have been an important factor of production from the agrarian economy. This paper makes a conclusion that the scientific methods of management by Taylor and his stress on efficiency improvement gave food of thought to others. Mayo and others focused on the soft components of workers’ life. These were the psychological and social components. This was the starting of the study of human resource management. Various theories of motivation, leadership, loyalty, perceptiuon, behaviour and others have developed. The contributions of Human Relations School of Management encouraged the managers and leaders to understand individuals’ various needs and develop their human resource strategies on the basis of that. This have demanded for an individual department in the organisations. It is Human Rsource Management department which independently handles the needs and requirements of the human resource. Hu

Family and social policy Essay Example | Topics and Well Written Essays - 3000 words

Family and social policy - Essay Example Throughout the eighties, they retained the plateau reached in divorce rates, and more than one-third of the marriages were likely to end in divorce. Focusing on these factors, Gittings (1993) argues that: 'There is no such thing as the family, and that no single form of the family has ever existed'. The impact of these changes has been perceptible for women at both ends of the childbearing years. In both age groups women have become less prone to be living as part of a married couple with children, and more prone to be either a lone parent, living alone or living as part of a childless couple. There has been a distinct shift for women from the role of spouse to the standing of the household head. Social and economic trends that have seen increased economic activity of women have conveyed these demographic developments. Though, socialists also distinguished eighties for the impact of economic recession and the rise of mass unemployment. These developments had a particular collision on families (mainly lone-parent families) and led to a threefold increase in the numbers of children living in poverty (Martin J, and Roberts C. 1984). In the death of a clear and wide-ranging model of family policy in Britain, response to demographic and social change has been incremental and sometimes contradictory. The family has increasingly become the center of political and public debate and disagreement. Attempts to persuade at times contrary objectives make any involvement in family policy exceedingly intricate.

Glacier Inn Essay Example for Free

Glacier Inn Essay Our strategy map for the Glacier Inn focuses on the four main dimensions of a business: a financial perspective, a customer perspective, an internal process perspective, and a learning and growth perspective. Each dimension plays a critical part in establishing a strong unified culture, and documents the primary objectives within the organization. For 2004, Glacier Inn has two main goals: to increase profitability and cash flow. The map outlined in Appendix A demonstrates how we will use these four dimensions to facilitate and implement different measures to achieve the desired strategies. With regards to the financial perspective, Glacier Inn can focus on a growth of revenue strategy and productivity strategy. In order to increase revenue, your main focus is to increase the capacity and quality of the hotel. We also believe there are other possible sources of revenue that could be implemented in order to further your capacity to generate income. Because Glacier Inn has such a short season and window of opportunity to make a profit, it is crucial that you make the most out of those winter months by enhancing your productivity and efficiency. The Glacier Inn is part of the service industry, and customer satisfaction plays an integral role in the success of your organization. Your vision statement is centered on delivering more than just place to spend the night; you are providing an experience, an experience of unmatched value and satisfaction. To achieve this, we believe that centering your organization around the culture of the First Nations people will be creating memories and providing adventures. Providing your customers with an unrivaled experience will include outdoor activities, traditional meals, quality service, native art work, individualized rooms, etc. Not only will these add value to the business and differentiate Glacier Inn from other Ice Hotels, but they can also serve as another source of revenue to aid in our revenue growth strategy. The internal process perspective is another important role in our strategy mapping. One of your main goals is to increase occupancy at the Glacier Inn, and we feel that it is important to focus the marketing efforts on the adventure campaign. Glacier Inn needs to showcase their unique business offerings inspired by nature, art, and culture. Due to the nature of the business, it is difficult for Glacier Inn to attract skilled and competent employees. With the development of an effective hiring and training process that also supports the culture that Glacier Inn is trying to create, they will be able to better serve their target market by attracting and retaining customers. Innovation is a key part of your internal process controls, and Glacier Inn wants to be working with ice experts for the development of different and unique ice themes. The final dimension of the Glacier Inn Strategy Map deals with a learning and growth perspective. In order to expand and advance within the entertainment industry, we want to mentor employee proficiency by working with and training the first nation’s people; by incorporating and encouraging culture both internally and externally; and by advancing with new technology through partnering with local colleges and universities in order to generate new innovations in ice making and preservation. All of these dimensions feedback and tie in with what Glacier Inn is trying to accomplish and what their vision is for the company. Issues Another issue that you have acknowledged is the restraint of hiring skilled and competent staff. The Glacier Inn is only open during the winter months, which makes it difficult to attract qualified and experienced employees. Glacier Inn is providing an experience of culture and excitement for their customers. Why not provide the same atmosphere for its employees. In the end, it’s not just about the money. Employees will be able to enjoy the same lifestyle and adventure that this environment has to offer. Glacier Inn can also invest in effective industry training programs to help and support the success of their hired personnel. We also want to address your concerns over changing the staff bonus plan. Currently, bonuses are being determined by profits alone. We agree that the implementation of the 2004 scorecard will provide a great method of measuring employee achievement. The balanced scorecard will provide feedback on whether the strategy is working to impact organizational performance. By measuring employees based subjectively on their scorecard execution, staff will be motivated and empowered to work in the best interests for themselves as well as the company. With employees being measured based on the strategy and implementation of Glacier Inn’s critical success factors, you can ensure that those goals become fundamental to their success as well. Employees are able to focus their attention on what matters most to the success of the organization. The Glacier Inn Hotel has another concern without the seasonal revenues. There is only a short window of opportunity to make profits, from January 4th to April 15th, and is primarily determined by the warming of the weather which can shorten this window. To off set the decrease in revenues in the summer, the hotel can offer customers a chance to stay in touch with nature. Two innovations will be needed to accomplish this, hiring of experienced outdoor staff and the building of year round facilities on the property. By offering summer outdoor actives such as fishing, hiking, and canoeing on guided tours the Glacier Inn can attract year round revenues. Also having facilities built on the property will allow customers places to stay in the summer as well as a warm place or customers to stay in the winter if they are not interested in sleeping in the cold rooms. Lastly, Glacier Inn hHotel lacks a specific measures, targets, and personal initiatives that are clear to the employes of the company. These need to be clearly defined to enhance the strategy and culture that needs to be wolves into the company. We have recommended a possible strategy map that can facilitate these initiatives. We have also chosen a proposition on how the Glacier Inn can continually add value and increase customer satisfaction. We included below a detailed plan of additional initiatives of adding customers value. Customer Value proposition Glacier Inn has competitors in more than just the hotel industry; it is competing with other forms of entertainment as well. The direct industry competitors of Glacier Inn Hotel are the hotel chains in the area, such as Super 8 Motel that offer a place to sleep and eat at a low price. However they do not offer an individualized customer experience. Glacier Inn also competes with other forms of entertainment in Northern Ontario. Places such as Moose Cree Outdoor Discoveries Adventures, which offers outdoor activities incorporated with the culture of the area. However, this experience is easily replicated. We believe that if Glacier Inn could combine the value of both of these industries into one unique location. The hotel must be unique. We have chosen product leadership as our way of adding value to customer offerings. Our recommendations for implementing this customer value from the hotel would be: Three Main Concepts For Product Leadership 1. Cree culture could be used to attract many customers foreign and domestic that are looking for a Canadian experience or wish to discover more about the first nations of Canada. Through cultural story telling, traditional foods, also traditional artwork and ices museum in the hotel lobby a broad audience can be drawn to the hotel. This will also allow the area to maintain its cultural identity and uniqueness while informing others. 2. The Glacier Inn could also offer outdoor winter activities such as snowshoeing, cross-country skiing, and wilderness sight seeing. Acquiring equipment traditional foods (maple syrup). When guests arrive at the hotel, staff could ask two questions: What do you want to experience? What are you not looking for? So that customers do feel pushed or pressured into experiences that’s are out of their fitness level. 3. Lastly, we believe that the individualized rooms will be an excellent way to attract customers to stay in each room. By pre-planning and designing each rooms theme the hotel can attract more customer to stay in the rooms overnight rather than just visiting the hotel for the day. Also ice sculptures will add a unique finishing touch to each room and can be a way of individualizing each room.

Ethernet system Essay Example for Free

Ethernet system Essay Robert Metcalfe with his colleagues at the Xerox Palo Alto research Center (PARC) developed the experimental Ethernet system. According to O’Reilly and associates (2000) the main purpose of developing the Ethernet system is to interconnect a personal workstation with graphical user interface called Xerox Alto. The experimental system was used in order to connect Altos and also printers and servers. The systems interface‘s signal clock was patterned in the Alto’s system clock. This resulted to 2. 94 Mbps. data transmission rate on the experimental Ethernet. Ethernet was originally known as Alto Aloha Network. Alto Aloha Network was changed its name to Ethernet by Metcalfe to indicate that the system not only support Alto’s but also other computers. And Metcalfe also point out that the Ethernet has progressed way beyond the Aloha system. He chose the name ether as to describe the essential feature of the system which is the physical medium carries bits to all stations the same way as the aluminiferous ether was once believe to proliferate There are two ways which can be used to allocate the capacity of transmission media: baseband and broadband transmissions. Baseband transmission allocates the entire capacity of the medium to one communication channel. It uses distinct values by measuring the voltage in wire which only carried one signal at a time. In broadband transmission, the system allows two or more communication channels to share the bandwidth of the communication medium. The system uses the technique of dividing the bandwidth into frequency bands which is called frequency division multiplexing (FDM) which works only with analog signals. There is also another technique called time-division multiplexing (TDM) that supports digital signals. Figure 1, show the difference between baseband and broadband transmission mode of operation: Figure 1. Difference in the mode of operation between baseband and broadband Broadband transmission is used in the web hosting companies. This is because of the higher speeds of the broadband. With the use of broadband, people can enjoy the full range of internet services like downloading videos, music, watching movies and plying online games. Transceivers have different speeds which are measured in MHz and also specified in wavelengths. The larger the value of the fiber core of the transceivers, measured in microns, there will be more bandwidth possible but also the distance will be shorter. The 1000 Base-LX is the long wavelength with a signaling speed of 1. 25 ±100 ppm GBd. This transceiver can use both 62. 5 and 50 micron multimode fiber and it also uses single-mode fiber optic cables with distances of 440m, 550m and 5 km. Another transreceiver is the 100 Base-TX which uses 4B5B binary encoding to encode 100 Mbps data stream in a signal of 125 MHz. One pair is used for transmitting data while the other pair is used for receiving the data. Given this, one user can setup a system for full duplex communication given that there are only interfaces in the same collision domain. It is either the two computers are directly connected to each other by crossover cable or a computer directly connected to a switch. Full duplex communication result to doubling the potential throughput but not often reached more than the modest improvement. Based on Sheldon and Big Sur Multimedia (2001), link aggregation is the process of connecting together two or more data channels in order to become a single channel which appears as a single, higher-bandwidth logical link. Also this aggregated links can provide redundancy and fault tolerance if the links follow different physical path. By linking the digital lines, the link aggregation improves the access to public networks. The aggregation is also use in enterprise network to build multigigabit backbone links. It also allows the network’s backbone speed to grow increasingly when the demands on the network increases without replacing everything and buy new and expensive hardware. Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol was intended for local area network (LAN) environments where in all the nodes are positioned few hundred feet from each other. The importance of the protocol is to listen up each node to the channels in a short period of time before it transmits. The main assumption of the protocol is that each node should be able to hear the transmission from every other station. But this assumption is violated in access network and this resulted to several problems. One of the serious problems encountered is the hidden transmitter problem. This occurs when the CSMA/CA cannot function properly due to a wireless node cannot hear one or more of the other nodes. And when this happen, multiple nodes attempt to transmit their data simultaneously over the shared data thus resulting to interference with each other. To address the hidden transmitter problem, the 802. 11 standard uses the protocol request to send/clear to send (RTS/CTS). Before transmitting each packet, each node transmit an RTS packet to other nodes to warn them that it is about to transmit data and after each transmission, it broadcasts CTS packet. This process is time and bandwidth consuming process and it is required for each and every transmission by each and every wireless node. But this process sill does not address the hidden transmitter problem fully because RTS/CTS packets are subjected to repeated collisions. In most applications, the wireless standard 802. 11b operating at 2. 4 ghz is ample enough. This wireless standard is the mostly widely accepted standard among the three wireless standards and also the price of the equipment is the cheapest because of the rising demand for the 802. 11g. Its distance will rely mostly on the communicating devices whether it have line of site or not. And with fewer obstacles among the transmitting and receiving devices, there will be better wireless connection and therefore much better web surfing. The 802. 11b wireless standard is good enough if using wireless route or access point only for internet usage because the connection to internet via broadband modem operates about 2mbps which is very fast. The 802. 11b transfer data at the rate of 11mbps which is sufficient for internet usage. This device saves money on equipment and gives great web surfing services. Another wireless standard being used is the 802. 11g standard. It is replacing the widely accepted standard which is the 802. 11b because both operate on the same frequency and the price drastically goes down on products. This standard is much very similar to 802. 11b because it also usually needs a line of site to achieve optical performance. Both standards, 802. 11b and 802. 11g operate at the same frequency range of 2. 4ghz and are inter-operable with each other. All the devices of 802. 11g can communicate with 802. 11 devices and the main advantage of the 802. 11g devices is that when transferring files betweens computers or networks, it is usually at a greater speed. It is recommended to use 802. 11g when using wireless connection to transfer files (data files, voice, music, and videos) around the home and office. 802. 11g standard also allows manufacturers to developed devices which work at speed of up to 108mbps because it recommended when transferring large data or audio files within LAN. Wi-Fi Protected Access (WPA) is a security technology that is used in wireless network. This was created by an industry trade group called the Wi-Fi Alliance which owns the trademark for the name Wi-Fi and certifies products that bear the name. WPA was created in order to response on the serious weaknesses of the previous system, the Wired Equivalent Privacy (WEP) and also to improve the authentication and encryption features of the WEP. It implements majority of the IEEE 802. 11i and intended to take place the place of WEP. It was designed in order to work with all wireless network interface cards but not with first generation wireless access point. Temporal Key Integrity Protocol (TKIP) is one of the key technologies behind WPA which deals with the encryption weaknesses of the WEP. Also the WAP have built-in authentication which is a key component. The WAP uses the RC4 stream cipher which has a 128-bit key and a 49-bit initialization vector (IV). With the combination of the TKIP and the RC4 stream cipher; this solves the problem of key recovery attacks which was found in WEP. In addition, the WPA provides much improved payload integrity. WPA uses a more secured message authentication code (MAC) but also termed as MIC which stand for message integrity code which is an algorithm â€Å"Michael†. MIC includes a frame counter preventing replay attacks. With the features of the WPA like having increased size of the keys and IV’s, reduced number of packets sent with related keys and adding up of a secured message verification system, it is far more difficult to break in within the system. There is one variation in WPA which is called the WPA pre shared key (WPA-PSK), which is also known as personal mode. This was designed for home and small office usage and networks which can’t afford the cost and complexity of the 802. 1X authentication server. To access the network, the user must enter a pass phrase, with 8 to 63 printable ASCII characters or 64 hexadecimal digits. This can be stored in the user’s computer with discretion under most operating system in order to avoid re-entry and must remain in the Wi-Fi access point. Protected Extensible Authentication Protocol (PEAP) securely transmits authentication information which includes password, over wired and wireless network. It is also an 802. 1x authentication type for wireless LAN’s. The PEAP is created by the Cisco Systems, Microsoft and RSA Security which is base on the Internet Draft submitted to the IETF. (Cisco Systems, 2007) The system uses only server side public key certificates which authenticate clients by creating encrypted SSL/TLS tunnel in between client and authentic server. This protects from casual inspection the resulting exchange of authentication. According to the Cisco Systems Inc. , the following are important benefits of the PEAP web security system: †¢ It relies on the Transport Layer Security (TLS) which allow non-encrypted authentication types (EAP-Generic Token Card and One Time Password (OTP)) support †¢ It uses the server-side Public-Key Infrastructure (PKI) based digital certification authentication †¢ It allows for the authentication to an extended suite of directories which include Lightweight Directory Access Protocol (LDAP), Novell NDS and OTPA databases †¢ It uses the TLS in order to encrypt all the user-sensitive authentication information †¢ It supports the password change at expiration †¢ It does not display the logon username in the EAP identity response †¢ The system is not susceptible to dictionary attacks †¢ It offer dynamic privacy protection while using in combination with Temporal Key Integrity Protocol (TKIP) or the Advanced Encryption Standard (AES) Also the PEAP have enterprise benefit. Based on the Cisco System Inc. , PEAP is based upon the server-side EAP-TLS. This means that organization can avoid the issue associated in the installing of digital certificates on every client machine which is required by the EAP-TLS. This provides the enterprise to choose what method of client authentication depending on their needs. PEAP authentication work in two phases: ? In phase 1, performing the server-side TLS authentication will result to creation of an encrypted tunnel and will achieve server-side authentication. One the process is done the data are encrypted with all the user-sensitive information ? For phase 2 according to the Cisco System Inc. , the client is authenticated by using methods like the EAP-GTC and the Microsoft Challenge Authentication Protocol (MS-CHAP) Public switched telephone network (PSTN) is referred as the public communication providing local, extended and long distance call telephone service. It is composed of telephone exchanges arranged in order to have nationwide telephone communication system. The system is open for those who can afford the service. Packets, pieces of the caller’s conversation are switched and then sent simultaneously to many connections to reach a receiver in the other end. All the phones in PSTN are connected in a way that any phone can call to any other phone due to all the local phone systems are connected to each other. Mitchell (2007) cited that PSTN provides the traditional Plain Old Telephone Service (POTS) to establishments and residences and also some parts of the PSTN are being utilized for DSL, VoIP and other internet-based network. In much relation to internet, this provides much of the internet’s long-distance infrastructure. Internet service providers (ISP) pay the long distance provider for the access to their infrastructure and they share the circuits among users in the process called packet switching. PSTN network link supports 64 kbps and in residences the PSTN phone lines carrying the bandwidth is made up of copper cable. Dial-up modems utilize 56kbps of the bandwidth when they are connected to a phone line. Also the PSTN utilizes the SS7 signaling protocol. SS7 signaling protocol support the exchange of special-purpose messages on public telephone networks. SS7 messages pass over separate channel different from the channel used for voice communication and it is referred as out of band signaling. Wireless local loop is sometimes called radio in the loop (RITL) or fixed –radio access (FRA). It is a system that connects users and subscribers to the public switched telephone network (PSTN) by the use of radio signals as substitute for copper for all part of the connection between subscriber and the switch. This includes cordless access systems; propriety fixed radio access and fixed cellular systems. One of the advantages of the wireless local loop is that it can be deployed in just weeks or months in comparison with copper wire systems which took months and years for the deployments. The instillation of the wireless local loop considerately has much lower construction cost than laying copper lines. The maintenance and operations of the wireless local loop are that easy and the average maintenance time per subscriber is shorter by 3 to 4 times. Signaling is the exchange between information which concerns about the establishment and in the control of a connection and the management of the network. There are many types of signaling: †¢ In-band signaling pertains to the exchange of signaling information within the same channel of the telephone call †¢ Out-of-band signaling is telecommunication signaling meaning exchange of information to control telephone call. It is done over a channel and it separates from channels which is use for telephone call. This signaling is used by Signaling system #7, the signaling standard controlling the world’s phone calls †¢ Line signaling is much concerned in transmitting information on the state of line or channel †¢ Register signaling is focused on the transmittance of information in the calling/ called telephone number †¢ Channels-associated signaling utilizes signaling channels dedicating to a specific bearer channel †¢ Common-channels signaling, utilizes signaling channels which transmit signaling information to multiple bearer channels. †¢ Compelled signaling pertains to the need of the receive signal to be fully acknowledged before the next signal is sent. †¢ Subscriber signaling pertains to the telephone and the telephone exchanges †¢ Trunk signaling pertains to the exchange.
