CELL BIOLOGY - Essay Example In the primary set, all crossovers with thiolase buildup 100 unblemished have been brought into the peroxisome, and those lacking buildup at least 100 stay in the cytosol. In the subsequent set, all cross breeds with buildup 125 or more noteworthy have been brought into the peroxisome, and those lacking buildup 125 or lesser stay in the cytosol. 3. Without hormones, protein B ties to protein An in the cytosol (following interpretation of protein An in the cytosol). This coupling forestalls access to the atomic vehicle hardware. This can occur from numerous points of view, two of which are portrayed here: protein B may veil the atomic localisation signal (as on account of the hsp90 - steroid hormone framework), or protein B may stay protein An in the cytosol. For each situation, the official of the hormone to either protein causes separation of the two proteins, and protein An approaches the atomic vehicle apparatus. In this way, in ordinary cells, protein B is constantly found in the cytosolic remove, though the nearness of hormone causes protein A to be found in the core, as opposed to the cytosolic extricate, where it is found without hormone. 4. A. The protein enters the ER and experiences the default pathway (ER->Golgi->Cell Surface). This is on the grounds that ER import is co-translational, while atomic import is post-translational. Along these lines, before the atomic import sign can be perceived, the protein is as of now inside the ER lumen. B. The protein is brought into the mitochondria. This is on the grounds that the atomic fare signal is not quite the same as the atomic import signal, subsequently the protein never enters the core, and the mitchondrial import signal is perceived in the cytosol ii) The odds of combination are expanded, at whatever point a similar protein (either Y or Z) is available on both benefactor and target layers. Consequently, when none of the two are available on both, the odds of combination is half of the maximal, when either Y or Z is available on the two films, odds of combination increments

Wireless technology - Free Essay Example

Introduction Handheld wireless radios such as this Maritime VHF radio transceiver use electromagnetic waves to implement a form of wireless communications technology. Wireless operations permits services, such as long range communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems (e.g. radio transmitters and receivers, remote controls, computer networks, network terminals, etc.) which use some form of energy (e.g. radio frequency (RF), infrared light, laser light, visible light, acoustic energy, etc.) to transfer information without the use of wires. Information is transferred in this manner over both short and long distances. Wireless technologies have become increasingly popular in our everyday business and personal lives. Cell phones offer users a freedom of movement unbelievable just over 10 years ago. Personal Digital Assistants (PDA) allow individuals to access calendars, e-mail, address and phone numbers lists, and the Internet. Global positioning system (GPS) that the location of the device anywhere in the world . Wireless technologies promise to offer even more features and functions in the next few years. An increasing number of government agencies, business, and home users are using wireless technologies in their environments. Overview of Wireless Technology Wireless technologies are enabling one or more devices to communicate without physical connections à ¢Ã¢â€š ¬Ã¢â‚¬Å" without requiring network cabling. Wireless technology aims to provide users access to information anywhere à ¢Ã¢â€š ¬Ã¢â‚¬Å" it allows mobility. Wireless technologies use radio transmissions for transmitting data, whereas wired technologies use cables. Wireless technologies range from complex systems, such as: * WLANs * Cell phones Simple device such as * Wireless headphone * Microphones Infrared devices such as * Remote Controls * Cordless computer keyboards * Mice In this article, a brief overview of critical elements of wireless is presented: wireless networks, wireless devices, wireless standards, Wireless Networks Wireless networks are categorized into three groups based on their coverage range: * WWAN * WLAN * WPAN ÃÆ'ËÅ" WWAN: WWAN representing wireless wide area networks includes wide coverage area technologies such as 2G cellular, Cellular Digital Packet Data (CDPD).

All of these technologies are join less à ¢Ã¢â€š ¬Ã¢â‚¬Å"receive and transmit information using electromagnetic (EM) waves. Wireless technologies use wavelengths ranging from the radio frequency (RF) The frequencies in the RF band cover a significant portion of the EM radiation spectrum, extending from 9 kilohertz (kHz), the lowest allocated wireless communications frequency, to thousands of gigahertz (GHz). Wireless Devices A wide range of devices use wireless technologies, with handheld devices being the most widespread form today. The most commonly used wireless handheld devices such as * Text messaging * PDA * Smart phone Personal Digital Assistants PDAs are data organizers that are small enough to fit into a shirt pocket or a purse. PDAs offer applications  · Office productivity * Database application * Address book, scheduler user allows synchronizing data between PDAs and personal computer. Smart Phones Mobile wireless telephones or cell phones have shortwave analog or digital transmission that allows users to establish wireless connections to nearby transmitters. As with WLANs, the transmitters span of coverage is called a cell. As the cell phone user moves from one cell to the next, the telephone connection is effectively passed from one local cell transmitter to the next. Todays cell phone is rapidly evolving to include integration with PDAs, thus providing users with increased wireless e-mail and Internet access. Mobile phones with information processing and data networking capabilities are called Smart Phones. Text-Messaging Devices Security administrators may also encounter one-way and two-way text messaging devices. These devices operate on a proprietary networking standard that disseminates e-mail to remote devices by accessing the corporate network. Text-messaging technology is designed to monitor a users inbox for new e-mail and relay the mail to the users wireless handheld via the Internet and wireless network. Wireless Standards Wireless encompasses a variety of standards. The principal advantages of standards are to encourage mass production and to allow products from multiple vendors to communicate. * AMPS (Advanced Mobile Phone Systems) * FDMA (Frequency Division Multiple Access) * TDMA (Time Division Multiple Access) * CDMA (Code Division Multiple Access) * GSM (Global System for Mobile) Many handheld devices (e.g., PDAs and cell phones) have followed the Wireless Application Protocol (WAP) standard, which provides for secure access to e-mail and the Internet. IEEE 802.11 Standards The following IEEE standards and task groups exist within the IEEE 802.11 working group:  · IEEE 802.11 The original 1 Mbit/s and 2 Mbit/s, 2.4 GHz RF and IR standard (1999) * IEEE 802.11a 54 Mbit/s, 5 GHzstandard (1999, shipping products in 2001) * IEEE 802.11b Enhancements to 802.11 to support 5.5 and 11 Mbit/s (1999) * IEEE 802.11c Bridge operation procedures; included in the IEEE 802.1D standard (2001) * IEEE 802.11d International (country-to -country) roaming extensions (2001) * IEEE 802.11e Enhancements: QoS, including packet bursting (2005) * IEEE 802.11F Inter-Access Point Protocol (2003) * IEEE 802.11g 54 Mbit/s, 2.4 GHz standard (backwards compatible with b) (2003) * IEEE 802.11i-Enhanced security (2004) * IEEE 802.11j Extensions for Japan (2004) * IEEE 802.11k Radio resource measurement enhancements * IEEE 8 0 2 .11l (reserved, typologically unsound) IEEE 802.11e Enhancements: * IEEE 802.11m Maintenance of the standard; odds and ends. * IEEE 802.11n Higher throughput improvements * IEEE 802.11o ( reserved, typologically unsound) * IEEE 802.11p WAVE Wireless Access for the Vehicular Environment. * IEEE 802.11r Fast roaming * IEEE 802.11s-ESS Mesh Networking * IEEE 802.11T Wireless Performance Prediction (WPP) test methods and metrics * IEEE 802.11u Interworking with non-802 networks (e.g., cellular) * IEEE 802.11v Wireless network management Photo phone The Photophone was invented jointly by Alexander Graham Bell and his assistant Charles Sumner Tainter on February 19, 1880. Bell believed the photophone was his most important invention. The device allowed for the transmission of sound on a beam of light. On June 3, 1880, Bell transmitted the worlds first wireless telephone message on his newly invented form of telecommunication, the far advanced precursor to fiber-optic communications. Of the eighteen patents granted in Bells name alone, and the twelve he shared with his collaborators, four were for the photo phone, which Bell referred to as his greatest achievement, writing that the photo phone was the greatest invention ever made, greater than the telephone. The master patent for the photo phone, was issued in December 1880, many decades before its principles could be applied to practical applications. Design and history The photo phone used crystalline selenium cells at the electricity. Worlds first wireless telephone communication June 1880 In their ÃŽÂ ©. It was the earliest fiber-optics system recorded. Radio The term wireless came into public use to refer to a radio receiver or Nobel Prize for Physics for their contribution to wireless telegraphy. 21st century development Internet radio Internet connections: no radio transmitters need be involved at any point in the process. Digital audio broadcasting Digital audio broadcasting (DAB): appears to be set to grow in importance relative to FM radio for airborne broadcasts in several countries. The electromagnetic spectrum Light, colors, AM and FM radio and electronic devices make use of the electromagnetic spectrum. In the US the frequencies that are available for use for communication are treated as a public resource and are regulated by the airplane. Wireless communication spans the spectrum from 9kHz to 300GHz. Security systems Wireless technology may supplement or replace hard wired implementations in security systems for homes or office buildings. Cellular telephony (phones and modems) A mobile phone or mobile (cellphone and headphone) is an GPS. The bottom of the economic pyramid. History of mobile phones Radio telephony (0G) In 1908, George Sweigert of Euclid, Ohio on June 10, 1969. In 1945, the zero generation (0G) of mobile telephones was introduced. Like other technologies of the time, it involved a single, powerful base station covering a wide area, and each telephone would effectively monopolize a channel over that whole area while in use. Analog cellular telephony (1G) The first commercial citywide cellular network was launched in Japan by NTT in 1979. Fully automatic cellular networks were first introduced in the early to mid-1980s (the FCC in the United States. The cell sites would be set up such that cells partially overlapped. In a cellular system, a signal between a base station and a terminal only need be strong enough to reach between the two, so the same channel can be used simultaneously for separate conversations in different cells. Cellular systems required several leaps of technology, including handover, which allowed a conversation to continue as a mobile phone traveled from cell to cell. This system included variable transmission power in both the base stations and the telephones, which allowed range and cell size to vary. As the system expanded and neared capacity, the ability to reduce transmission power allowed new cells to be added, resulting in more, smaller cells and thus more capacity. The evidence of this growth can still be seen in the many older, tall cell site towers with no antennae on the upper parts of their towers. These sites originally created large cells, and so had their antennae mounted atop high towers; the towers were designed so that as the system expandedà ¢Ã¢â€š ¬Ã¢â‚¬ and cell sizes shrankà ¢Ã¢â€š ¬Ã¢â‚¬ the antennae could be lowered on their original masts to reduce range. Digital mobile communication (2G) The first modern network technology on digital Telecom Finland who ran a 1G NMT network. The first data services appeared on mobile phones starting with person-to-person SMS text messaging in Finland in 1993. First trial payments using a mobile phone to pay for a Coca Cola vending machine were set in Finland in 1998. The first commercial payments were mobile parking trialled in Sweden but first commercially launched in Norway in 1999. The first commercial payment system to mimic banks and credit cards was launched in the Philippines in 1999 simultaneously by mobile operators Globe and Smart. The first content sold to mobile phones was the ringing tone, first launched in 1998 in Finland. The first full internet service on mobile phones was i-Mode introduced by NTT DoCoMo in Japan in 1999. Wideband mobile communication (3G) In 2001 the first commercial launch of WCDMA standard. Until the early 1990s, following introduction of the miniaturization of digital components and the development of more sophisticated batteries, mobile phones have become smaller and lighter. Uses Mobile phones are used for a variety of purposes, including keeping in touch with family members, conducting business, and having access to a telephone in the event of an emergency. Some individuals keep multiple cell phones in some cases for legitimate reasons such as having one phone for business and another for personal use, though a second cell phone may also be used to covertly conduct an affair or illicit business transaction. Child predators are able to take advantage of cell phones to secretly communicate with children without the knowledge of their parents or teachers, which has raised concerns. Organizations that aid victims of domestic violence offer a secret cell phone to potential victims. These devices are often old phones that are donated and refurbished to meet the victims emergency needs. The victim can then have the phone handy when necessary and without the abuser knowing. A study by Motorola found that one in ten cell phone subscribers have a second phone that often is kept secret from other family members. These phones are used to engage in activities including extramarital affairs or clandestine business dealings. Handsets There are several categories of mobile phones, from basic phones to feature phones such as music phones and camera phones. There are also smartphones; the first smartphone was the iPhone. Smartphone Mobile phones often have features beyond sending touchscreen. SIM card Typical mobile phone SIM card In addition to the battery, postage stamp, the SIM Card is usually placed underneath the battery in the rear of the unit, and stores the phones configuration data, and information about the phone itself, such as which calling plan the subscriber is using. When the subscriber removes the SIM Card, it can be re-inserted into another phone that is configured to accept the SIM card and used as normal. Each SIM Card is activated by use of a unique numerical identifier; once activated, the identifier is locked down and the card is permanently locked in to the activating network. For this reason, most retailers refuse to accept the return of an activated SIM Card. Those cell phones that do not use a SIM Card have the data programmed in to their memory. This data is accessed by using a special digit sequence to access the NAM as in Name or number programming menu. From here, one can add information such as a new number for your phone, new Service Provider numbers, new emergency numbers, change their Authentication Key or A-Key code, and update their Preferred Roaming List or PRL. However, to prevent someone from accidentally disabling their phone or removing it from the network, the Service Provider puts a lock on this data called a Master Subsidiary Lock or MSL. The MSL applies to the SIM only so once the contract has been completed the MSL still applies to the SIM. The phone however, is also initially locked by the manufacturer into the Service Providers MSL. This lock may be disabled so that the phone can use other Service Providers SIM cards. Most phones purchased outside the US are unlocked phones because there are numerous Service Providers in close proximity to one another or have overlapping coverage. The cost to unlock a phone varies but is usually very cheap and is sometimes provided by independent phone vendors. Media The mobile phone became a mass media channel in 1998 when the first ringtones were sold to mobile phones by Radiolinja in Finland. Soon other media content appeared such as news, videogames, jokes, horoscopes, TV content and advertising. In 2006 the total value of mobile phone paid media content exceeded internet paid media content and was worth 31 Billion dollars. The value of music on phones was worth 9.3 Billion dollars in 2007 and gaming was worth over 5 billion dollars in 2007. The mobile phone is often called the Fourth Screen or Third Screen .It is also called the Seventh of the Mass Media. Most early content for mobile tended to be copies of legacy media, such as the banner advertisement or the TV news highlight video clip. Recently unique content for mobile has been emerging, from the ringing tones and ring back tones in music to mobisodes, video content that has been produced exclusively for mobile phones. The advent of media on the mobile phone has also produced the opportunity to identify and track Alpha Users or Hubs, the most influential members of any social community. AMF Ventures measured in 2007 the relative accuracy of three mass media, and found that audience measures on mobile were nine times more accurate than on the internet and 90 times more accurate than on TV. Comparison to similar systems Car phone A type of telephone permanently mounted in a vehicle, these often have more powerful transmitters, an external antenna and loudspeaker for hands free use. They usually connect to the same networks as regular mobile phones. Cordless telephone (portable phone) Cordless phones are telephones which use one or more radio handsets in place of a wired handset. The handsets connect wirelessly to a base station, which in turn connects to a conventional land line for calling. Unlike mobile phones, cordless phones use private base stations, and which are not shared. Professional Mobile Radio Advanced professional mobile radio systems can be very similar to mobile phone systems. Notably, the TETRA, the European digital PMR standard, to implement public mobile networks. Radio phone This is a term which covers radios which could connect into the telephone network. These phones may not be mobile; for example, they may require a PSTN phone call. Satellite phone This type of phone communicates directly with an artificial satellite, which in turn relays calls to a base station or another satellite phone. A single satellite can provide coverage to a much greater area than terrestrial base stations. Since satellite phones are costly, their use is typically limited to people in remote areas where no mobile phone coverage exists, such as mountain climbers, mariners in the open sea, and news reporters at disaster sites. IP Phone This type of phone delivers calls over GSM networks. Several vendors have developed standalone Wi-Fi phones. Additionally, some cellular mobile phones include the ability to place VoIP calls over cellular high speed data networks and/or wireless internet. Effect on Health Mobile phone radiation and health Because mobile phones emit precautionary principle be observed, recommending that use and proximity to the head be minimized, especially by children. People specifically fear the consequences that electromagnetic radiation might have on children. In order to avoid harm, a variety of initiatives have been created. For example, one initiative states that Mobile towers be located further away from child-care centers or schools where there are larger concentrations of children. Restriction on usage Schools Some schools limit or restrict the use of mobile phones. Schools set restrictions on the use of mobile phones because of the use of cell phones for cheating on tests, harassing other people, causing threats to the schools security, and facilitating gossip and other social activity in school. Many mobile phones are banned in school locker room facilities, public restrooms and swimming baths. Production Many mobile phones, along with other electronic products, have high quality turn a blind eye to its original source or do not adequately trace the source. Wi-Fi Wi-Fi (pronounced IEEE 802.11 standards. Because of the close relationship with its underlying standard, the term Wi-Fi is often used as a synonym for IEEE 802.11 technology. The Wi-Fi Alliance is a global, non-profit association of companies that promotes WLAN technology and certifies products if they conform to certain standards of interoperability. Not every IEEE 802.11-compliant device is submitted for certification to the Wi-Fi Alliance, sometimes because of costs associated with the certification process and the lack of the Wi-Fi logo does not imply a device is incompatible with Wi-Fi devices. Today, an IEEE 802.11 device is installed in many laptop or palm-sized computers. Uses Internet access A roof mounted Wi-Fi antenna A Wi-Fi enabled device such as a wireless mesh networks, for example, in London. garden sheds. City-wide Wi-Fi A municipal wireless antenna in Minneapolis In the early 2000s, many cities around the world announced plans for a city wide Wi-Fi network. This proved to be much more difficult than their promoters initially envisioned with the result that most of these projects were either canceled or placed on indefinite hold. A few were successful, for example in 2005, United States to offer city wide free Wi-Fi.Few of the Municipal Wi-Fi firms have now entered into the field of Smart grid networks. Campus-wide Wi-Fi The first Wi-Fi network in the world was actually a campus based network. Carnegie Mellon University went live with the first-ever Wi-Fi network in 1994. Direct computer-to-computer communications Wi-Fi also allows communications directly from one computer to another without the involvement of an access point. This is called the ad-hoc mode of Wi-Fi transmission. This personal computers. However the Wi-Fi Alliance is hoping to promoting this method for quick file transfers and media sharing through a new discovery and easy security setup which they are calling Wi-Fi Direct. Wi-Fi certification Wi-Fi Alliance Wi-Fi technology is based on IEEE 802.11 standards. The backward compatibility, and to promote wireless local area network technology. Today the Wi-Fi Alliance consists of more than 300 companies from around the world. Manufacturers with membership in the Wi-Fi Alliance, whose products pass the certification process, are permitted to mark those products with the Wi-Fi logo. Specifically, the certification process requires conformance to the IEEE 802.11 radio standards, the EAP authentication standard. Certification may optionally include tests of IEEE 802.11 draft standards, interaction with cellular phone technology in converged devices, and features relating to security set-up, multimedia, and power saving. The Wi-Fi name The term Wi-Fi suggests Wireless Fidelity, compared with the long-established audio recording term High Fidelity or Hi-Fi. Wireless Fidelity has often been used in an informal way, even by the Wi-Fi Alliance itself, but officially the term Wi-Fi does not mean anything. The Wi-Fi Alliance initially stated that Wi-Fi actually stood for Wireless Fidelity, as with the White papers still held on their website say: a promising market for wireless fidelity (Wi-Fi) network equipment. The Alliance has since downplayed the connection to Hi-Fi. Their official position now is that it is merely a brand name that stands for nothing in particular, and they now discourage the use of the term Wireless Fidelity. Advantages and challenges A keychain size Wi-Fi detector. Operational advantages Wi-Fi allows local area networks (LANs) to be deployed without wires for client devices, typically reducing the costs of network deployment and expansion. Spaces where cables cannot be run, such as outdoor areas and historical buildings, can host wireless LANs. Wireless network adapters are now built into most laptops. The price of chipsets for Wi-Fi continues to drop, making it an economical networking option included in even more devices. Wi-Fi has become widespread in corporate infrastructures. Different competitive brands of access points and client network interfaces are inter-operable at a basic level of service. Products designated as Wi-Fi Certified by the Wi-Fi Alliance are backwards compatible. Wi-Fi is a global set of standards. Unlike mobile phones, any standard Wi-Fi device will work anywhere in the world. Wi-Fi is widely available in more than 220,000 public hotspots and tens of millions of homes and corporate and university campuses worldwide. The current version of passphrase is used. New protocols for Quality of Servicemake Wi-Fi more suitable for latency-sensitive applications, and powers saving mechanism improve battery operation. Limitations Spectrum assignments and operational limitations are not consistent worldwide. Most of Europe allows for an additional 2 channels beyond those permitted in the U.S. for the 2.4 GHz band. Japan has one more on top of that. Europe, as of 2007, was essentially homogeneous in this respect. A very confusing aspect is the fact that a Wi-Fi signal actually occupies five channels in the 2.4 GHz band resulting in only three non-overlapped channels in the U.S.: 1, 6, 11, and three or four in Europe: 1, 5, 9, 13 can be used if all the equipment on a specific area can be guaranteed not to use 802.11b at all, even as fallback or beacon. dBm. Hardware Standard devices An Czech Republic. OSBRiDGE 3GN 802.11n Access Point and UMTS/GSM Gateway in one device. USB wireless adapter A data between connected wireless devices in addition to a (usually) single connected wired device, most often an Ethernet hub or switch, allowing wireless devices to communicate with other wired devices. USB, Express Card, Card bus and PC Card. Most new laptop computers are equipped with internal adapters. Internal cards are generally more difficult to install. Wireless AirPort. Wireless data-link layer. Two wireless bridges may be used to connect two wired networks over a wireless link, useful in situations where a wired connection may be unavailable, such as between two separate homes. Wireless range extenders or wireless repeaters can extend the range of an existing wireless network. Range extenders can be strategically placed to elongate a signal area or allow for the signal area to reach around barriers such as those created in L-shaped corridors. Wireless devices connected through repeaters will suffer from an increased latency for each hop. Additionally, a wireless device connected to any of the repeaters in the chain will have a throughput that is limited by the weakest link between the two nodes in the chain from which the connection originates to where the connection ends. Distance records Distance records (using non-standard devices) include 382km (237 mi) in June 2007, held by Ermanno Pietrosemoli and EsLaRed of Venezuela, transferring about 3 MB of data between mountain tops of El Aguila and Platillon. The Swedish Space Agencytransferred data 310km, using 6 watt amplifiers to reach an overhead stratospheric balloon. Embedded systems Embedded serial-to-Wi-Fi module Wi-Fi availability in the home is on the increase.This extension of the Internet into the home space will increasingly be used for remote monitoring. Examples of remote monitoring include security systems and tele-medicine. In all these kinds of implementation, if the Wi-Fi provision is provided using a system running one of operating systems mentioned above, then it becomes unfeasible due to weight, power consumption and cost issues. Increasingly in the last few years, embedded Wi-Fi modules have become available which come with a real-time operating system and provide a simple means of wireless enabling any device which has and communicates via a serial port. This allows simple monitoring devices à ¢Ã¢â€š ¬Ã¢â‚¬Å" for example, a portable ECG monitor hooked up to a patient in their home à ¢Ã¢â€š ¬Ã¢â‚¬Å" to be created. This Wi-Fi enabled device effectively becomes part of the Internet cloud and can communicate with any other node on the Internet. The data collected can hop via the homes Wi-Fi access point to anywhere on the Internet. These Wi-Fi modules are designed so that designers need minimal Wi-Fi knowledge to wireless-enable their products. Network security The main issue with wireless network security is its simplified access to the network compared to traditional wired networks such as firewall. Most business networks protect sensitive data and systems by attempting to disallow external access. Thus being able to get wireless reception provides an attack vector, if encryption is not used or can be defeated. Attackers who have gained access to a Wi-Fi network can use DNS spoofing attacks very effectively against any other user of the network, because they can see the DNS requests made, and often respond with a spoofed answer before the queried DNS server has a chance to reply. Securing methods A common but unproductive measure to deter unauthorized users is to suppress the APs spoofing an authorized address. Kleins attack to crack a WEP key with a 50% success rate using only 40,000 packets. Wireless energy transfer An artists depiction of a solar satellite, which could send energy wirelessly to a space vessel or planetary surface. Wireless energy transfer or wireless power transmission is the process that takes place in any system where wires. Wireless transmission is useful in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible. Wireless energy transfer is different from wireless transmission for the purpose of telecommunications, such as power received, becomes critical if it is too low to recover the signal successfully. With wireless energy transfer efficiency is the more important parameter. The most common form of wireless power is carried out using lasers. Microwave Microwave power transmission The earliest work in the area of wireless transmission via radio waveswas performed by Nikola Tesla also investigated radio transmission and reception. Japanese researcher Yagi antenna. While it did not prove to be particularly useful for power transmission, this beam antenna has been widely adopted throughout the broadcasting and wireless telecommunications industries due to its excellent performance characteristics. Power transmission via radio waves can be made more directional, allowing longer distance power beaming, with shorter wavelengths of electromagnetic radiation, typically in the beaming of power to spacecraft leaving orbit has been considered. Power beaming by microwaves has the difficulty that for most space applications the required aperture sizes are very large due to Thinned array curse, it is not possible to make a narrower beam by combining the beams of several smaller satellites. For earthbound applications a large area 10km diameter receiving array allows large total power levels to be used while operating at the low power density suggested for human electromagnetic exposure safety. A human safe power density of 1mW/cm2 distributed across a 10km diameter area corresponds to 750 megawatts total power level. This is the power level found in many modern electric power plants. Laser With a laser beam centered on its panel of photovoltaic cells, a lightweight model plane makes the first flight of an aircraft powered by a laser beam inside a building at NASA Marshall Space Flight Center. In the case of electromagnetic radiation closer to visible region of spectrumcan be transmitted by converting electricity into a solar cell receiver. This mechanism is generally known as Power Beaming because the Power is beamed at a receiver that can convert it to usable electrical energy. Bluetooth The Bluetooth standard describes how mobile phones, computers, and PDAs should interconnect with each other, with home and business phones, and with computers using short range wireless connections. Bluetooth network applications include wireless synchronization, e-mail/Internet/intranet access using local personal computer connections, hidden computing through automated applications and networking, and applications that can be used for such devices as hands-free headsets and car kits. The Bluetooth standard specifies wireless operation in the 2.45 Gigahertz (GHz) radio band and supports data rates up to 720kbps. Bluetooth is an open wireless protocol for exchanging data over short distances (using short radio waves) from fixed and mobile devices, creating personal area networks (PANs). It was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization. Implementation Bluetooth uses a radio technology called frequency-hopping spread spectrum, which chops up the data being sent and transmits chunks of it on up to 79 frequencies. In its basic mode, the modulation is Gaussian frequency-shift keying (GFSK). It can achieve a gross data rate of 1 Mb/s. Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, Global Positioning System (GPS) receivers, digital cameras, and video game consoles through a secure, globally unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency bandwidth. The Bluetooth specifications are developed and licensed by the Bluetooth Special Interest Group (SIG). The Bluetooth SIG consists of companies in the areas of telecommunication, computing, networking, and consumer electronics. Uses Bluetooth is a standard and a communications protocol primarily designed for low power consumption, with a short range based on low-cost transceiver microchips in each device. Bluetooth makes it possible for these devices to communicate with each other when they are in range. Because the devices use a radio communications system, they do not have to be in line of sight of each other. In most cases the effective range of class 2 devices is extended if they connect to a class 1 transceiver, compared to a pure class 2 network. This is accomplished by the higher sensitivity and transmission power of Class 1 devices. List of applications A typical Bluetooth mobile phone headset. More prevalent applications of Bluetooth include: * Wireless control of and communication between a mobile phone and a hands-free headset. This was one of the earliest applications to become popular. * Wireless networking between PCs in a confined space and where little bandwidth is required. * Wireless communication with PC input and output devices, the most common being the printer. * Transfer of files, contact details, calendar appointments, and reminders between devices with OBEX. * Replacement of traditional wired GPS receivers, medical equipment, bar code scanners, and traffic control devices. * For controls where infrared was traditionally used. * For low bandwidth applications where higher [USB] bandwidth is not required and cable-free connection desired. * Sending small advertisements from Bluetooth-enabled advertising hoardings to other, discoverable, Bluetooth devices. * Wireless bridge between two Industrial Ethernet networks. * Two seventh-generation PlayStation 3, use Bluetooth for their respective wireless controllers. * Dial-up internet access on personal computers or PDAs using a data-capable mobile phone as a wireless modem like Novatel Mifi. Bluetooth vs. Wi-Fi IEEE 802.11 in networking Bluetooth and Wi-Fi have many applications in todays offices, homes, and on the move: setting up networks, printing, or transferring presentations and files from PDAs to computers. Both are versions of unlicensed wireless technology. local area network access in work areas. Bluetooth devices A Bluetooth USB dongle with a 100m range. Bluetooth exists in many products, such as telephones, the citation needed], modems and headsets. The technology is useful when transferring information between two or more devices that are near each other in low-bandwidth situations. Bluetooth is commonly used to transfer sound data with telephones or byte data with hand-held computers. Bluetooth protocols simplify the discovery and setup of services between devices. Bluetooth devices can advertise all of the services they provide. This makes using services easier because more of the security, network address and permission configuration can be automated than with many other network types. Mobile phone requirements A mobile phone that is Bluetooth enabled is able to pair with many devices. To ensure the broadest support of feature functionality together with legacy device support, the Open Mobile Terminal Platform (OMTP) forum has recently published a recommendations paper, entitled Bluetooth Local Connectivity; see external links below to download this paper. Series of Bluetooth Bluetooth 1.0 and 1.0B Versions 1.0 and 1.0B had many problems, and manufacturers had difficulty making their products interoperable. Versions 1.0 and 1.0B also included mandatory Bluetooth hardware device address transmission in the Connecting process (rendering anonymity impossible at the protocol level), which was a major setback for certain services planned for use in Bluetooth environments. Bluetooth 1.1 * Ratified as IEEE Standard 802.15.1-2002. * Many errors found in the 1.0B specifications were fixed. * Added support for non-encrypted channels. * Received Signal Strength Indicator (RSSI). Bluetooth 1.2 This version is backward compatible with 1.1 and the major enhancements include the following: * Faster Connection and Discovery * Adaptive radio frequency interference by avoiding the use of crowded frequencies in the hopping sequence. * Higher transmission speeds in practice, up to 721 Kbit/s, than in 1.1. * Extended Synchronous Connections (eSCO), which improve voice quality of audio links by allowing retransmissions of corrupted packets, and may optionally increase audio latency to provide better support for concurrent data transfer. * UART. * Ratified as IEEE Standard 802.15.1-2005. * Introduced Flow Control and Retransmission Modes for L2CAP. Bluetooth 2.0 This version of the Bluetooth specification was released on November 10, 2004. It is backward compatible with the previous version 1.2. The main difference is the introduction of an Enhanced Data Rate (EDR) for faster data transfer. The nominal rate of EDR is about 3 megabits per second, although the practical data transfer rate is 2.1 megabits per second.According to the 2.0 specification, EDR provides the following benefits: * Three times the transmission speed (2.1Mbit/s) in some cases. * Reduced complexity of multiple simultaneous connections due to additional bandwidth. * Lower power consumption through a reduced duty cycle. Bluetooth 2.1 Bluetooth Core Specification Version 2.1 is fully backward compatible with 1.2, and was adopted by the Bluetooth SIG on July 26, 2007.[12] It supports theoretical data transfer speeds of up to 3 Mb/s. This specification includes the following features: Bluetooth 3.0 The 3.0 specification was adopted by the UWB, but UWB is missing from the specification. Telephone control protocol Telephony control protocol-binary is the bit-oriented protocol that defines the call control signaling for the establishment of voice and data calls between Bluetooth devices. Additionally, TCS BIN defines mobility management procedures for handling groups of Bluetooth TCS devices. TCS-BIN is only used by the cordless telephony profile, which failed to attract implementers. As such it is only of historical interest. Adopted protocols Adopted protocols are defined by other standards-making organizations and incorporated into Bluetooths protocol stack, allowing Bluetooth to create protocols only when necessary. The adopted protocols include: Point-to-Point Protocol (PPP) Internet standard protocol for transporting IP datagrams over a point-to-point link TCP/IP/UDP Object Exchange Protocol (OBEX) Session-layer protocol for the exchange of objects, providing a model for object and operation representation Wireless Application Environment/Wireless Application Protocol (WAE/WAP) WAE specifies an application framework for wireless devices and WAP is an open standard to provide mobile users access to telephony and information services. Bluetooth Security Bluetooth implements E0 stream cipher is used for encrypting packets, granting confidentiality and is based on a shared cryptographic secret, namely a previously generated link key or master key. Those keys, used for subsequent encryption of data sent via the air interface, rely on the Bluetooth PIN, which has been entered into one or both devices. In September 2008, the National Institute of Standards and Technology (NIST) published a Guide to Bluetooth Security that will serve as reference to organization on the security capabilities of Bluetooth and steps for securing Bluetooth technologies effectively. While Bluetooth has its benefits, it is susceptible to denial of service attacks, eavesdropping, man-in-the-middle attacks, message modification, and resource misappropriation. Users/organizations must evaluate their acceptable level of risk and incorporate security into the lifecycle of Bluetooth devices.

Music Makes Sense free essay sample

Music Makes Sense by N. S., Cranston, RI To most, those small black dots and lines on paper seem overwhelming and confusing, but to me they make perfect sense. Although complicated and challenging at times, music is a part of who I am. Between the music I play in the band room and the music that comes from my stereo, I have found a song to describe every emotion. I know songs that describe my fears and sorrows and songs that express my joys and happiness. I realized at an early age that my singing voice would not earn me a place on the cover of a CD. Rather than accepting this as a setback, I looked toward the next best thing: musical instruments. The piano and the clarinet became my introduction to the world of music. Playing the piano taught me the necessary skills to master some of musics most renowned pieces; Twinkle Twinkle Little Star and Hot Cross Buns, to name two.

The band made me listen to more than just the words of a song and listen to the music which, for me, has a language of its own.

The narrators role in Blood Brothers Essay Example

The narrators role in Blood Brothers Paper The narrators role in Blood Brothers is quite unusual. The convention of the narrator in most plays is such that they are usually brought on to introduce the next part of the play and then move offstage and the play continues. However, in Blood Brothers the narrator is a physical character and is on stage all of the time. At the beginning of the play the narrator says, So did y hear the story of the Johnston twins? This indicates that he is the storyteller. His presence at every scene thereafter shows that he is telling us about that part of the story. The narrator is on stage all the time, watching the characters and often lurking in the background, and this makes him seem a sinister and threatening character, which contrasts with other plays where the narrator is usually neutral. The narrator contributes to the dramtic effect in numrous ways. For instance let us look at the fact that the narrator enters at the side of the stage, and also at the fact that the narrator leaves and enters the stage at such times that it has an enormous impact upon the audinace;up to the extent that even when the narrator is not to be seen and is not there the audinace have this emotion in which they express that the narrator is omniscuent. For instance the play states the following The devils got your number this suggests that the narrator is becoming powerful, and the fact that he knows whats going on that he is all seeing.

Aswellas that we see that Russell is using many dramtic effects such as, he lays the scene just like the well known play Romeo and Juliet by Shakespeare. In both plays we are told the ending by bthe narrator right at the start. For instance in the play BloodBrothers we see that the narrator states And did you never know how the Jhonstones died, straight away we are told that they shall die similarly we are also told this in Romeo and Julliet in which it says where civil blood makes civil hands unclean this again tells us that that they will die. Throughtout the play we see that the narrator gives this feeling as if he is some supenatural being. Another way in which the narratorgives a dramtic effect is of when he talks in direct speech to the audinace which makes them feel as if he is one of them, it feels as if they are apart of this thus keeping them informed, and in the know. Conversely the narrator is speaking in a Liverpuddlian accent this renforce the effect if making the audinace feel as if he is one of them and the fact that the same problem occurs in their city, and the it goes on in their day to day lives. We can also see the fact that the narrator is starting to be used as Russels mouth piece. We can tell of this because he is now protraying a message which will be fullfilled at the end of the play. The narrator is a vital piece of he play and a fundelmentle part of the dramatic effects of the play because without him the ethical message of the whole play would be in pieces. Theres a deal been sealed, a pact been born this line gives the feeling of prophecy , because itis stated by the narrator whio within the playgains some sort of jurisprudence authority which somehow gives it a prophetical effect. Let me take your to the fact that the words deal been sealed have been used in the context to protray a signing or an agreement ona contract. Let us look at the word deal in particular which has been used in such a manner that one cannot evade it without any understanding, and the fact that it is right at the point where none can misunderstand. this is in genral gives the emotion of the that no going back option and alos emphizes the fact that of religious belief by swearing on the bible. It authanticates the whole of the contract the whole deal it gives it the seal of approval. Allow me to take your attention to the born which has also used in such a manner that the audiance is taken back by it. The word born in this context brings about the sence of this evil being awakened and the fact the this immoral-being is on the rise. Happy are y cointent at last ? wiped what happened forgotten the past no one gets off without a price being paid. From this alone we see the emince power in the play and the fact the it contains powerful and destructive dramatic effects. This statement provides the effect the past has no forgotten them and the fact it is coming back to get them. Again this is said by the narrator who now is forming into Mrs Johnsons point onwards. We can also see that the Englished used within the play is far from standered English; but instead one could say theat it was urban,common,northern or colloquial English. This type of English is commonly used within that city and area,which is always spoken in the Liverpuddlian accent. This again is one of many dramtic effect used in the play to convey its moral message.

The World Is Not Enough Essays

The World Is Not Enough Essays The World Is Not Enough Essay The World Is Not Enough Essay James Bond films have a completely individual genre, their ongoing action style is different from any others of its kind. The Bond films are a very popular mainly British icon, although they do hold a global appeal. They are all made by MGM, holding a huge budget, which enables its ongoing success. Therefore, the director will try to meet the demands of the huge audience who have come to expect certain things from the film such as its iconography, eg. the contrast between good and evil characters, the constant sense of danger and the race against time, etc. The money supporting this Blockbuster brings about expectation of spectacular effects, various locations, big high-status stars, sexy women, the well-known Bond theme tune, etc. However, the story line, the settings and the characters must all signify Bond and these particular expectations of the audience. The extract I have chosen to study is one of immense action and great suspense. We begin by viewing the meeting of the Bond girl and the Bond villain. The use of media language is therefore crucial at this stage in enabling the audience to understand the importance of these first key scenes. The first scene establishes the setting, a wide shot of an open location showing Bond landing in Kazakhstan. This is signified by their landing, on a dusty airstrip, with graphics to give the location on screen. The Bond theme tune is meanwhile playing in the background, connoting that Bond has arrived in the foreign territory and that there may soon be danger on its way. This is signified by the exposed airstrip and warning music that we are used to in these situations. Bond then travels to the key location in which the scene is further set, with further establishing shots which are important in giving the audience a clearer pictur of where the action will take place and who will be involved. This suspense and danger is signified mainly by the people who Bond shares a jeep with all with shaven heads, wearing dark overalls, portraying of course an evil darkness. The changing of the music further emphasises this point in which it increases in pace and adds to the present situation by the special effects of explosions in the vicinity, and faster cutting to add speed to the sequence. There is a lot of non-verbal communication going on here, to begin with showing evil signs of danger and authority. Thus the narrative is starting to be built up. As we see a laboratory, the music transforms to more intricate, computer like music. It is well lit with people wearing white suits. This connotes that this will be a key location, adding to our knowledge and stirring at our curiosity levels. It also signifies a place of delicacy in comparison to the previous fast and loud scene, hereby adding to the connoted level of meaning within the scene. A wide shot establishes the next scene as Bond enters an important nuclear facility. We recognise this from the mise-en-scene with people moving about, their clothing, the explosions, warning signs, alarms, etc. These aspects all contribute to a sense of danger. As it cuts to the star Bond, we can basically understand that he is in a dangerous position, adding to the effect of us as an audience, feeling the danger. This is further signified by Bond being met by a burly, uniformed man with a Russian accent and the juxtaposition of shots from below the ground of warheads being taken from the bunker. The next key location involves the meeting between Bond and Dr Christmas Jones (Denise Richards). She stands out as a star and her importance is demonstrated within the the scene by being shot removing a clinical, white radiation suit. The camera then tilts to reveal a stunning body drawing a positive reaction from Bond, possibly signifying a possible interest. This encounter with the Bond girl is common, however this is the first time in which Bond reaches the nemesis. Whilst they meet and interact, there are many cus, this connotes that they are both key characters and the star is clearly shown. NVC is important particularly here as Jones shows no interest in Bond, this perhaps signifies a non-conformist Bond girl who has adapted more to the social beliefs of the late 90s. However, as expected, Bond stays cool throughout, for example when he is questioned by Jones on his Russian, he replies in russian; I studied at Oxford, signifying his coolness and his position as our hero is is secured by Jones double-take as he walks away. The signifiers of glamour further support the star quality of Jones, she is always shot with soft lighting and wears make-up, with a necklace that somehow contrasts with her working clothes of tight shorts and vest. She is portrayed as a strong woman presumably this has been developed through the political changes within society, so in fact she is demonstrating an attitude of the expected new 90s woman. These things are key in connoting sexiness and a love interest. Throughout this scene, mise-en-scene was very important a spark was established between two main characters, we learn much about them and also the surroundings that they are both working in. The next scene begins with Bond entering the bunker. Effects are used here as Bond is travelling downwards, the FX are accompanying him into what is signified as an abyss. There various signifiers at this point, he is shot from a high angle, losing his normal position of authority. He then enters the darkness followed by random, eerie sfx, all connoting danger and risk. As we are introduced to the setting from Bonds point of view, adding to our empathy, we see low lighting, smoke, controls and explosives. The scene is set with these shots and the audience is quite easily able to gain meaning from the various signifiers. Our next focus is at the end of a tunnel in which sparks are flying. The scene, again is established through the use of a long shot demonstrating to the audience that they are experiencing a key location of the scene. Following Bonds approach, suspense is added as the mystical Bond music increases pace and we are left to wonder what lies through the tunnel. However, this information is slowly revealed as Bond sees some me working on a nuclear warhead. At this point, we are shown at the same time as Bond, creating a sense of realism and timing. There is a sudden change in the music at this point signifying the presence of Renard whose nvc can be immediately interpreted as villainous. He has a shaven head, wearing a completely dark outfit and is shouting whilst being approached from a high angle. This connotes his power and his sense of evil, being mainly shotin darkness. Throughout the sequence, the music increases the intensity with the action.This is mainly demonstrated when Bond confronts Renard. As the shot is from Renards POV at a high angle, this perhaps suggests that Bond is still not on top of things. However, the main focus is on Bonds gun and his good figure is signified by the blue tint of lighting surrounding his face, in comparison to Renards face of darkness. Whilst the two of them exchange remarks, the pace is signified through the use of hand-held camera shots with increased cuts, signifying again the star status , although more importantly to the audience, these being the key characters within the film. As the narrative develops, again we learn more about the characters, much of this can in fact be learnt through the signifiers such as, Bonds white shirt in comparison to Renards fully zipped, dark uniform. Also, Renards voice connotes an eastern villain, linking to previous Bond sagas. Music does, however play a key part throughout the entire scene. The iconography does play a large part all through the film, it does not fail to live up to the audiences expectations, for example, the commonly known Bond catchphrase is included The names Bond.James Bond etc. as usual, this is mentioned mid-action on an elevator, whilst saving Dr Christmas Jones whilst Renard escapes. As Bond films have been going for such a long time, it has become easier to distinguish the advance in the technology used over time and how the representaions of this have developed, according to its era. The action is ongoing and Bond doesnt stop until hes achieved his victory. The amazing quality of each Bond film demonstrates just how much effort and money has been put into it, it is completely obvious that it has had a huge budget by just focusing on the use of actors, special effects, cuts and angles, etc.

A Review Article on Concept Mapping

A Review Article on Concept Mapping A concept is a perceived regularity in events or objects designated by a label. Concept maps are graphical tools for organizing and representing knowledge in networks of concepts and linking statements about a problem or subject (Novak one for pathophysiology and one for care planning. It is sometimes easier to follow a care map if diagnoses, goals and interventions are placed in different shaped figures such as circles, octagons, and triangles. Concept mapping is used broadly in nursing education. Nursing faculty may employ them as a teaching strategy in the classroom and students may use them as a note taking or study tool. There are multiple structures used for concept mapping. They are an effective way to teach learners how to think about concepts and to see the big picture of how the many facts and variables in a situation fit together. Objectives Concept maps have been used in nursing education as a method for students to organize and analyze data. This review article examine s empirical studies on the use of concept maps as a metacognitive tool, as a tool improve students’ critical thinking abilities and as a teaching-learning method in nursing and discusses the effectiveness of using concept mapping in the nursing education.

Torts problem question-Negligent misstatements Case Study

Torts problem question-Negligent misstatements - Case Study Example Whoever makes a claim due to somebody's negligence besides proving duty of care, breach and damages, must also show extra factors under 'duty' As pure economic loss caused by negligence is not a tort but liability under common law negligence. In Hedley Byrne & Co Ltd v Heller & Partners Ltd [1963]1 UKHL 4 (28 May 1963, it was held by the House of Lords that respondents were not liable as bankers for giving negligently favourable opinion about their client whom the appellants dealt with as a result. The reason was that the bankers had no fiduciary relationship with the appellants nor had any duty of care to them as there was no contract. Besides they had cautioned the appellants that their opinion was without owning any responsibility. Applying the same principle in the above case, it can be argued that though the bankers had been in the process of making a fiduciary relationship subject to the surveyor's opinion, such a relationship had not been established. There was also no negligence on the part of the bankers. Besides they also had relied on Surveyor's opinion and lost business as a result. In fact Helen and the Bank are in the same position. On the other hand whether Helen as well as Andrew can claim compensation from the Surveyor depends on the principles of duty of care, fiduciary relationship, and negligence. ... But proximity of relationship could be deemed to exist as two of them have suffered due to his negligent opinion. Therefore both Helen and Andrew can claim damages from him. In fact, valuer was held liable in Can v Wilson2, wherein the valuer was held responsible to the mortgagees for negligent undervaluation and was asked to pay loss incurred by the mortgagees due to mortgagor's default. In this case, the defendant who was the valuer sent his valuation report to the agent of plaintiff (mortgagee) in order to induce him to advance money against the mortgage of the property he valued. As the valuer had knowingly placed himself in that position, he had a duty of care in the preparation of a valuation document. In somewhat identical cases, Smith v. Eric S. Bush and Harris v. Wyre Forest District Council [1989]3, both the plaintiffs purchased houses relying on valuations of the surveyors who acted under the instructions of the defendant mortgagees and their fees were paid by the plaintiff purchasers. The valuations of the surveyors turned out to be defective resulting in serious financial loss to the plaintiffs. Even though the terms of agreement excluded liability for both the mortgagees and the surveyors for any loss due to inaccuracy in valuation, the House of Lords held that surveyors had a duty of care to the plaintiffs and the terms of exclusion of liability was struck down by virtue of section 2(2) and 11 (3) of the Unfair Contract Terms Act 1977. B In the case of B.Pen & Co, Charles lent money to James to buy the business of B.Pen & Co, relying on the Accountant's report which later turned out to be untrue to the detriment of both Charles and John.

growaw Personal Growth and Death of Edna Pontellier in Kate Chopins The Awakening :: Chopin Awakening Essays

The Awakening:   Personal Growth and Death      The Awakening is a novel about the growth of a woman becoming her own person; in spite of the expectations society has for her. The book follows Edna Pontellier   as she struggles to find her identity. Edna knows that she cannot be happy filling the role that society has created for her. She did not believe that she could break from this pattern because of the pressures of society. As a result she ends up taking her own life.   However, readers should not sympathize with her for taking her own life.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Edna Pontellier was on her way to an awakening. She realized during the book, she was not happy with her position in life. It is apparent that she had never really been fully unaware   However, because her own summary of this was some sort of blissful ignorance. Especially in the years of life before her newly appearing independence, THE READER SEES HOW she has never been content with the way her life had turned out. For example she admits she married Mr. Pontellier out of convenience rather than love. EDNA knew he loved her, but she did not love him. It was not that she did not know what love was, for she had BEEN INFATUATED BEFORE, AND BELIEVED IT WAS love. She consciously chose to marry Mr. Pontellier even though she did not love him. When she falls in love with Robert she regrets her decision TO MARRY Mr. Pontellier. HOWEVER, readers should not sympathize, because she was the one who set her own trap. She did not love her husband whe n she married him, but SHE never once ADMITS that it was a bad decision. She attributes all the problems of her marriage to the way IN WHICH SOCIETY HAS defined the roles of men and women. She does not ACCEPT ANY OF THE BLAME, AS HER OWN.   The only other example of married life, in the book, is Mr. and Mrs. Ratignolle, who portray the traditional role of married men and women of the time. Mr. Pontellier also seems to be a typical man of society. Edna, ON THE OTHER HAND, was not A TYPICAL WOMAN OF SOCIETY. Mr. Pontellier knew this but OBVIOUSLY HAD NOT ALWAYS. This shows IS APPARENT in the complete lack of constructive communication between the two. If she had been able to communicate with her husband they may have been able to work OUT THEIR PROBLEMS, WHICH MIGHT HAVE MADE Edna MORE SATISFIED WITH her life.

Learning Disabilities in Society Today Essay

The modern society has advanced very much compared to the earlier society, for example of the mid twentieth century. This advancement can be attributed to various technological innovations and inventions that have taken place in the society. The various spheres of change have impacted both positively and negatively on the welfare of the people. This is together with the welfare of those with disabilities. Disability has been and remains to be a major aspect of social inquiries and studies that has been conducted in the society. This is given that the disabled persons are part and parcel of the society. In this regard, the issue of disability as an area of study encompasses various aspects. This is for instance the kind of relationships between disability and work, disability and oppression, disability and education and disability and discrimination among others. In addition, studies on disability have centered on the measures that have been taken or ought to be taken to address the issue. The measures taken range from medical interventions and efforts to change the attitude of the members of the society towards the disabled people. Disability and the Society Today: Overview There are several definitions that have been proposed for the term disability. The definitions depend on the orientation and experiences of the scholar. For example, in law, the term disability can be used to connote a physical or mental impairment of an individual (Shah & Priestly, 2009). For the impairment to qualify as a disability, the law requires that it must have a substantial and long term negative effect on the individual’s ability to carry out normal day to day activities (Valentino & Skeletonk, 2009). However, not all such conditions qualify as disabilities. For example, individuals with ailments such as cancer, HIV/AIDS and those who are blind or partially sighted are not considered as been disabled. According to the legal definition given above, impairments considered to make an individual disabled include sensory impairments, such as sight and hearing, or mental impairments such as learning disabilities, dyslexia and mental illness (Bradley, Danielson & Hallahan, 2002). Some severe disfigurements, for example those affecting limbs and other physical organs, are regarded as a disability. Some conditions that can worsen over time such as multiple scleroses are also regarded as a disability as soon as they are diagnosed, even before they start to affect the individual’s day to day activities (Lerner, 2000). There are criteria that have been put in place to determine whether a disability is long term or not. For example, for a disability to de regarded as long term, it must have lasted for at least one year (Bradley et al, 2002). Disabilities that have lasted for less than one year can also be classified as long term. This is when there are sufficient grounds to expect the disability to last for at least one year after its onset (Barnes, Fletcher & Fuchs, 2007). For example, a loss of both limbs can be considered as a long term disability even if the loss is barely one month old. Also, for a disability to be regarded as long term, it must be expected to last for the rest of the individual’s life (Barnes et al, 2007). As earlier alluded to in this paper, there are several types of disabilities affecting people in the society. These range from physical disability, mental disability among others. Another type of disability that affects people in the society, albeit not so visible, is learning disability. This paper is going to look at learning disabilities within the context of the modern society. A general overview of disability has already been provided to create a context within which learning disability will be located.

Women In Victorian Era Essay - 1347 Words

During the Victorian era, women were viewed as the very opposite of what a man ought to be. In the words of John Stuart Mill, who published a criticism of the way society differentiated between males and females The female sex was brought up to believe that its ‘ideal of character’ was the very opposite to that of men’s ‘not self-will , and government by self-control, but submission, and yielding to the control of others to live for others; to make complete abnegation of themselves, and to have no life but in their affections.’† (171) Basically, women were expected to be sweet, docile, and man’s perfect helpmate. Contrary to that belief, throughout the Victorian era the view of women began to change, at least in the mind of some.†¦show more content†¦The heroine, Cathy, is the very essence of an unconventional Victorian woman. Cathy is wild, undisciplined, rowdy, and disheveled. She could almost be considered tomboyish in nature. She is definitely not the picture of a â€Å"proper† Victorian girl. I believe that the reason Cathy is as she is, however, is because of the influence of her playmate Heathcliff, who is a reckless, moody young man who brings chaos and bad behavior to everyone he encounters. Compare Cathy to her neighbor Isabella Linton at Thrushcross Grange. Isabella is quiet, neat, dainty, caring, obedient, and well mannered. She bows in deference to the wishes of the men in her life. She is the epitome of what a â€Å"proper† Victorian girl should be like. Although Cathy does eventually begin to dress and behave more like she should, it is only after she comes into contact with the traditional Linton family. Nelly Dean, the family’s faithful housekeepers who has had to put up with much of Cathy’s reckless ways, is amazed at the change in Cathy after her short visit with the Linton’s. â€Å"Instead of a wild, hatless little savage jumping into the house†¦ there lighted from a handsome black pony a very dignified person, with brown ringlets falling from the cover of a feathered beaver, and a long cloth habit, which she was obliged to hold up with both hands that she might sail in.† Cathy had been transformed from her previous ways; at least it seemed to be the case.
