Connection Project - Research Paper Example Most significantly, they identified statistical measures such as the standard deviation, coefficient and correlation (Nelson, 2000). The importance of information gathering and analysis in the 21st Century is a constant requirement for individuals, institutions and governments. Present day society is faced with endless and varied uncertainties concerning the future. The availability of-and access to accurately-synthesized information, therefore, helps in making informed predictions about the future, in planning and provides a basis for assessing performance over a forecasted period. The application of statistics has been embraced globally (most importantly) due its ability to fit into all fields of human interest. This has turned statistics into an inter-disciplinary subject (Pangano, 2008). Discussion The applicability of statistics is derived from the core process of data mining. The process of acquiring raw data is the first step towards making relevant statistical inferences and applications designed to assist in solving real world problems faced by both individuals and organizations. The extent to which applications can be made is only limited by the researcher’s definition of the problem statement and the methodology employed for data mining. This means that the statistical inference is legitimized by the problem being investigated and the set procedures for collecting and analyzing information concerning the problem (McPherson, 2011). Essentially, one can perhaps rightly argue that the choice of policy, strategy or decision undertaken was decided upon by the intrinsic nature of the problem thereby challenging the traditional view of managerial competency as the primary factor in decision making. Statistics becomes exceedingly essential in qualitative thinking. It identifies the type of problem facing individuals or institutions, defines the problem, assesses it and relates it to the final set of alternative courses of actions available in remedy t o the problem (Nelson, 2000). It provides a logical approach to problem solving thereby enriching the ability of individuals and organizations alike to make near accurate forecasts for the future now. Statistics becomes a tool for identifying and successfully effecting change within organizations by minimizing the variations between expected and actual results. With regard to applications by individuals, statistics can be used in enriching financing decisions. An investor wishing to invest his savings will rely heavily on quantitative statistics to identify investment alternatives that provide satisfactory returns to his investment at minimal risk exposures (McPherson, 2011). Quantitative statistics, therefore, assists in creating a benchmark portfolio for investment by identifying the set of securities that the investor will hold. The performance of the securities and the portfolio managers can be accurately assessed at different points in time to make relevant adjustments. Statist ics can be used by graduates in deciding as between employers and versus self employment. The career path of an individual within an organization can be assessed using industry aggregates on salary packages, determining future growth and development opportunities within the firm (promotions and training) and in formulating personal targets. It is a normal practice for firms to be ranked at both industry level and

Health Leads Essay As recently mentioned, there will be a health focus to a workshop on climate change in Melbourne this weekend that is being put on by the Green Institute. One of the speakers is Senator Richard Di Natale, the Greens health spokesperson, who writes below that we need to focus more on the underlying causes of poor health. On related themes, don’t miss this New York Times article which profiles an organisation working on the social causes of poor healt. Health Leads trains about 1000 volunteers each year to staff resource desks in the waiting rooms of hospital clinics or health centers in Baltimore, Boston, Chicago, New York, Providence, R. I., and Washington. At these sites, doctors now regularly â€Å"prescribe† a wide range of basic resources — like food assistance, housing improvements, or heating fuel subsidies — which the Health Leads volunteers â€Å"fill†, by applying their problem solving skills to identify resources anywhere they may be available. Health Leads was co-founded by a Harvard University student, Rebecca Onie, in 1996 and up until a year ago, she thought that the organisation’s biggest obstacle would be getting doctors to pay attention to patients’ social needs. But the organisation now gets so many referrals from doctors that it has waiting lists. According to the report, Health Leads offers a model of how to develop a workforce to systematically address the social causes of illness The real crisis in health Not many people give up a career in medicine to become a politician. However, I still have the same goal: the good health of Australians. Australia’s health care system isn’t bad. We spend less on health care than many other countries, about 9% of GDP (less than half of that spent in the USA), but most of us get access to high quality care when we need it. But we are also one of the most hospitalised nations in the world, with more overnight beds per capita than any other OECD country. And even with the relatively high rate of hospitalisation, 60 per cent of our population is overweight, half the teeth of Australians aged 35-44 have some decay and alcohol abuse is costing our economy billions each year and rising. Australia isn’t having a health crisis. We’re having a preventative health crisis. The cost of a hospital bed is considerable, but we’re failing to invest in measures that prevent people from needing that bed in the first place. Dental health is a prime example of the opportunity we have to transform our health system through better preventative measures. Currently, 650,000 Australians are on public dental care waiting lists, and dental admissions are the highest cause of acute preventable hospital admissions. Illness due to untreated dental disease is costing us dearly. Yet less than 20 per cent of dental care is currently funded by the Government, compared to nearly 80 per cent of general medical services. For alcohol abuse and obesity as well, there are many preventative measures we can take to reduce the enormous costs to our economy each year. In addition to publicly funded dental care, I will be working towards a phase-out of alcohol and junk-food advertising during sports broadcasts, a more rational alcohol taxation system and better food labelling regulations. It doesn’t take much imagination to see how a small investment in prevention can save us large costs in cure. And with greater preventative health measures, we have more opportunity to address the social inequalities in health in Australia. Health isn’t just a physical condition. If you have less income and less education, you are more likely to have poorer health. Beyond genetic make-up, behaviour and access to medical care, social inequality is still a strong determinant of health. This is especially acute when it comes to the health of Indigenous communities. Climate change is emerging as a major health issue, and once again, those who are more likely to suffer health problems due to climate change are those on the lower end of the socio-economic scale. During heatwaves and other extreme weather events, we have seen that the poor, the elderly and children are most affected. Already, our changing climate is creating a rise in vector-borne diseases, such as Dengue Fever, Malaria and Ross River Fever, and increasing rates of gastroenteritis will also take a heavier toll on the most vulnerable.

How Does Digital Radio Work Computer Science Essay

How Does Digital Radio Work Computer Science Essay Digital audio broadcasting, also known as digital radio and high-definition radio, is audio broadcasting in which analogy audio is converted into a digital signal and transmitted on an assigned channel in the FM frequency range. DAB is said to offer compact disc (CD) quality audio on the FM (frequency modulation) broadcast band and to offer FM-quality audio on the AM (amplitude modulation) broadcast band. Digital radio works by combining two digital technologies to produce an efficient and reliable radio broadcast system: An audio compression system, called MPEG, reduces the vast amount of digital information required to be broadcast. It does this by discarding sounds that will not be perceived by the listener for example, very quiet sounds that are masked by other, louder sounds and hence not required to be broadcast, and efficiently packages together the remaining information COFDM technology, (Coded Orthogonal Frequency Division Multiplex) ensures that signals are received reliably and robustly, even in environments normally prone to interference. Using a precise mathematical relationship, the digital data signal is split across 1 536 different carrier frequencies, and also across time. This process ensures that even if some of the carrier frequencies are affected by interference, or the signal disturbed for a short period of time, the receiver is still able to recover the original sound. The interference which disturbs FM reception, caused by radio signals bouncing off buildings and hills (multi-path) is eliminated by COFDM technology. It also means that the same frequency can be used across the entire country, so no re-tuning of sets is necessary when travelling, or taking a portable receiver to a different area. Instead of having a different frequency for each radio station, digital radio combines several services together in what is called a multiplex. The multiplex is able to carry stereo and mono radio channels as well as services such as text and data. The UK has been allocated seven multiplexes by the Radio Authority in the spectrum 217.5 230.0 MHz. It is possible to carry more services on this one frequency allowing the spectrum to be used more efficiently. The multiplex has a gross capacity of 2,300,000 bits which are used for carrying audio, data and an in-built protection system against transmission errors. Of these about half the bits are used for the audio and data services. Throughout the day, the data capacity allocated to each service can be varied by the broadcaster. Each multiplex can carry a mixture of stereo and mono audio services and data services too; the number of each dependent on the quality required. A multiplex is a technical term used for a number of stations sharing just one frequency to transmit its services. It is a digital transmitter located within a region broadcasting stations operated by a company or group (e.g. BBC, Digital One, Switch Digital etc). So what are DABs benefits and the cost Listeners in most major towns and cities in the world and it can receive between 30 and 50 radio stations with digital radio, in many cases thats more than double whats available on analogue. And its not just more of the same the content within that choice of stations is unique and exciting, delivering station formats that just dont exist on analogue. The FM spectrum is so clogged right now that theres no room for new stations that would expand listeners choice with, for example, soul music, or country music, or big band swing, or any of the other 100+ brands that are available uniquely to DAB. Digital radio receivers have a screen on which stations can transmit information via Dynamic Label Segments (DLS). Some stations already transmit the latest news, travel, and weather, whats on now and next, Web site addresses and phone numbers. Tomorrows radios will offer much more sophisticated data. The potential for advertisers to use the DLS facility on DAB for targeted advertising is an exciting prospect, and in the future, advertisers can use DAB to deliver Internet-type commercials. Because digital radio uses the spectrum more efficiently than analogue, it is possible to broadcast more channels using the same frequency, making room for broadcasters to expand their station portfolios. It also offers less noise. DAB digital radio delivers improved sound quality. The technology allows the receiver to lock on to the strongest signal it can find and ignore everything else. This eliminates the hiss, crackle and fade so familiar on analogue radio. A BLOCK DIAGRAM OF A DAB RADIO http://focus.ti.com/graphics/blockdiagram/blockdiagram_images/6243.gif This diagram above is about what goes on in a DAB radio. In order to receive a station the Low-Noise Amplifiers (LNA) boosts the RF signal from the antenna. The frequency synthesizer generates a Local Oscillator (LO) signal that is mixed with the RF input to form the IF signal. The high-speed ADC converts the IF signal into digital samples. Depending on the speed of the signal the DAC outputs as compared to what the DSP or microcontroller can handle, a Digital Down counter may be required. The power supply is connected to the 12V or 24V board net and regulates down/up to voltages for DSP, uC, memory and ICs and functions in the infotainment system. In some cases there may be 10 or more different power rails, making the design of the power supply a critical task when trying to design for size, cost and efficiency. Linear regulators with low quiescent current help reduce battery leakage current during standby operating modes (ignition off), are load dump voltage tolerant for directly battery connected devices, and need low drop out and tracking for low battery crank operation. Beyond providing increased conversion efficiencies, switching power supplies provide EMI improvement with slew rate control of the switching FET, Frequency hopping, spread spectrum or triangulation method for attenuation of peak spectral energy, Low Iq, soft start for power sequencing and in rush current limitation, Phased switching for multiple SMPSs regulators to minimize input ripple current and lower input capacitance, higher switching frequency for smaller components (L and Cs), and SVS functions for brown out indications The Audio input front end and audio output is often combined into a single Codec. On the output side ADCs convert the digital output an analog signal, which is amplified to the levels needed by the speakers or headphones used with the system. By using Class-D amplifiers the systems power efficiency can exceed 90% while maintaining low THD. This improved efficiency leads to significant size, weight and heat reductions. TIs class-D car audio solutions exhibit extremely low EMI levels and are being used in OEM systems with stringent EMC requirements. The audio DSP performs I/Q demodulation and outputs digital audio and data. This includes functions like volume, treble, bass and sound effects. THE COMPONENT OF A RADIO TRANMITTER WAVE A transmitter can be defined as an electronic device which, usually with the aid of an antenna, propagates an electromagnetic signal such as radio, television, or other telecommunications. http://www.hardware-one.com/reviews/dab/DRS-small.gif A transmitter can be made by coupling the output of an oscillator directly to an antenna. The primary purpose of the oscillator is to develop an rf voltage which has a constant frequency and is immune to outside factors which may cause its frequency to shift. The output of this simple transmitter is controlled by placing a telegraph key at point K in series with the voltage supply. Since the plate supply is interrupted when the key is open, the circuit oscillates only as long as the key is closed. Transmitter http://www.tpub.com/neets/book12/0059.GIF Capacitors C2 and C3 can be GANGED (mechanically linked together) to simplify tuning. Capacitor C1 is used to tune (resonate) the antenna to the transmitter frequency. CA is the effective capacitance existing between the antenna and ground. This antenna-to-ground capacitance is in parallel with the tuning capacitors, C2 and C3. Since the antenna has capacitance, any change in its length or position, such as that caused by swaying of the antenna, changes the value of CA and causes the oscillator to change frequency. Because these frequency changes are undesirable for reliable communications, the multistage transmitter was developed to increase reliability. Reception of a DAB signal The DAB ensemble is selected from the antenna to the analogue tuner, the output is fed to the demodulator and channel decoder to eliminate transmission errors. The information contained in the FIC is passed to the user interface for selection and is used to set up the receiver appropriately. http://www.hardware-one.com/reviews/dab/fig3.jpg Receiving of DAB signal RATIO DETECTOR The ratio demodulator uses a double-tuned transformer to convert the instantaneous frequency variations of the fm input signal to instantaneous amplitude variations. These amplitude variations are then rectified to provide a dc output voltage which varies in amplitude and polarity with the input signal frequency. This detector demodulates fm signals and suppresses amplitude noise without the need of limiter stages. The input tank capacitor (C1) and the primary of transformer T1 (L1) are tuned to the center frequency of the fm signal to be demodulated. The secondary winding of T1 (L2) and capacitor C2 also form a tank circuit tuned to the center frequency. Tertiary (third) winding L3 provides additional inductive coupling which reduces the loading effect of the secondary on the primary circuit. Diodes CR1 and CR2 rectify the signal from the secondary tank. Capacitor C5 and resistors R1 and R2 set the operating level of the detector. Capacitors C3 and C4 determine the amplitude and polarity of the output. Resistor R3 limits the peak diode current and furnishes a dc return path for the rectified signal. The output of the detector is taken from the common connection between C3 and C4. Resistor RL is the load resistor. R5, C6, and C7 form a low-pass filter to the output. Ratio detector http://www.tpub.com/neets/book12/0261.GIF This circuit operates on the same principles of phase shifting as did the Foster-Seeley discriminator. In that discussion, vector diagrams were used to illustrate the voltage amplitudes and polarities for conditions at resonance, above resonance, and below resonance. The same vector diagrams apply to the ratio detector but will not be discussed here. Instead, you will study the resulting current flows and polarities on simplified schematic diagrams of the detector circuit. What is amplitude modulation? Amplitude modulation (AM) can be defined as a technique used in electronic communication, also is use as transmitting information via a radio carrier wave. AM works by varying the strength of the transmitted signal in relation to the information being sent. In order for a radio signal to carry audio or other information for broadcasting, it must be modulated or changed in some way. Although there are a number of ways in which a radio signal may be modulated, one of the easiest, and one of the first methods to be used was to change its amplitude in line with variations of the sound. The basic concept surrounding what is amplitude modulation, is quite straightforward. The amplitude of the signal is changed in line with the instantaneous intensity of the sound. In this way the radio frequency signal has a representation of the sound wave superimposed in it. In view of the way the basic signal carries the sound or modulation, the radio frequency signal is often termed the carrier. What is amplitude modulation, AM Amplitude Modulation    When a carrier is modulated in any way, further signals are created that carry the actual modulation information. It is found that when a carrier is amplitude modulated, further signals are generated above and below the main carrier. To see how this happens, take the example of a carrier on a frequency of 1 MHz which is modulated by a steady tone of 1 kHz. The process of modulating a carrier is exactly the same as mixing two signals together, and as a result both sum and difference frequencies are produced. Therefore when a tone of 1 kHz is mixed with a carrier of 1 MHz, a sum frequency is produced at 1 MHz + 1 kHz, and a difference frequency is produced at 1 MHz 1 kHz, i.e. 1 kHz above and below the carrier. If the steady state tones are replaced with audio like that encountered with speech of music, these comprise many different frequencies and an audio spectrum with frequencies over a band of frequencies is seen. When modulated onto the carrier, these spectra are seen above and below the carrier. It can be seen that if the top frequency that is modulated onto the carrier is 6 kHz, then the top spectra will extend to 6 kHz above and below the signal. In other words the bandwidth occupied by the AM signal is twice the maximum frequency of the signal that is used to modulate the carrier, i.e. it is twice the bandwidth of the audio signal to be carried. Amplitude demodulation Amplitude modulation is one of the most straightforward ways of modulating a radio signal or carrier. The process of demodulation, where the audio signal is removed from the radio carrier in the receiver is also quite simple as well. The easiest method of achieving amplitude demodulation is to use a simple diode detector. This consists of just a handful of components:- a diode, resistor and a capacitor. AM diode detector AM Diode Detector In this circuit, the diode rectifies the signal, allowing only half of the alternating waveform through. The capacitor is used to store the charge and provide a smoothed output from the detector, and also to remove any unwanted radio frequency components. The resistor is used to enable the capacitor to discharge. If it were not there and no other load was present, then the charge on the capacitor would not leak away, and the circuit would reach a peak and remain there. POWER SUPPY Most of the Dab radio is use by batteries. Also there three parts is a battery which are an anode (-), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a traditional battery) are hooked up to an electrical circuit. http://www.qrg.northwestern.edu/projects/vss/docs/media/Power/battery.gif The chemical reactions in the battery cause a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. In a battery, the only place to go is to the cathode. But, the electrolyte keeps the electrons from going straight from the anode to the cathode within the battery. When the circuit is closed (a wire connects the cathode and the anode) the electrons will be able to get to the cathode. In the picture above, the electrons go through the wire, lighting the light bulb along the way. This is one way of describing how electrical potential causes electrons to flow through the circuit.

Employee Involvement Essay

The direct participation of staff to help an organization fulfill its mission and meet its objectives by applying their own ideas, expertise, and efforts towards solving problems and making decisions. From this definition, participation can include representative participation, direct communication, and upward problem solving. We will focus on the latter two categories because this article is more about understanding outcomes, tools, and methods. The direct participation of staff to help an organization fulfill its mission and meet its objectives by applying their own ideas, expertise, and efforts towards solving problems and making decisions. Based on the thinking that people involved in a process know it best, regular participation of employees in several planning and execution areas occur. Major areas are: (1) deciding how work gets done, (2) suggesting improvements, (3) setting goals, (4) planning, and (5) performance monitoring. That employees will improve their performance if t hey are more motivated by being more involved, is an observed trait. Borders on empowerment. Employee involvement means that every employee is regarded as a unique human being, not just a cog in a machine, and each employee is involved in helping the organization meet its goals. Each employee’s input is solicited and valued by his/her management. Employees and management recognize that each employee is involved in running the business. Employee empowerment is a somewhat different concept. It means that in addition to involving employees in running the business, employees and management recognize that many problems or obstacles to achieving organizational goals can be identified and solved by employees. Employee empowerment means that management recognizes this ability, and provides employees with the tools and authority required to continuously improve their performance. The management states its expectations about employees recognizing and solving problems, and empowers them to do so. Employee Motivation  is the â€Å"psychological forces that determine the direction of a person’s behavior in an organization, a person’s level of effort and a person’s level of persistence Using rewards as motivators divides employee motivation into two categories: intrinsic and extrinsic motivation. Intrinsic rewards are internal, psychological rewards such as a sense of accomplishment or doing  something because it makes one feel good.[7] Extrinsic rewards are rewards that other people give to you such as a money, compliments, bonuses, or trophies. â€Å"the willingness to exert high levels of effort toward organizational goals, conditioned by the effort’s ability to satisfy some individual need.† Theory XTheory x states that people are generally lazy. Since people are lazy they will try at all costs to avoid work. They will do what they can to waste time and find other things to do. Sigmund Freud the creator of this theory believed that the only way to get people to do work was to threaten them with punishment if they didn’t do their work. This idea is important because if it holds true, motivation becomes extremely important.

Second Language Acquisition

Second Language Acquisition Many factors can influence the children’s success in learning the second language. Being brought up in the bilingual family, a person can develop speech skills in both languages simultaneously or in sequence. That is why, both languages can affect each other because of similarities or differences in their structures and semantics. Family and school environments are important to affect the process of learning two languages.Advertising We will write a custom research paper sample on Second Language Acquisition specifically for you for only $16.05 $11/page Learn More Thus, the degree of the second language learning and acquisition can be assessed with references to the number and character of errors made by the learner while using the second language for communicating with the other people. During the process of acquisition of two languages, a child can make developmental errors, transfer errors, and mix languages while communicating orally, and the char acter of these errors can be analyzed in order to make conclusions about the level of the second language acquisition. When a child is brought up in the family where parents use two languages to communicate with each other the child can make definite errors and mix languages while attempting to present his or her thought because these two languages used within the common environments can influence each other. Developmental errors are characteristic for a person when two languages are learnt simultaneously or when a child at the first stage of learning the second language (Paradis, Genesee, Crago, 2011). Developmental errors are the speech mistakes which can be made by any young person because the basics of the language are not learnt fully, and only the first efforts to use the second language correctly are made by a child. Thus, it is possible to state that developmental errors are rather natural in their character because they are not caused by the impact of the other language (P aradis, Genesee, Crago, 2011, p. 265). The examples of such errors are the wrong word order, grammatical mistakes, and the omission of morphemes. For instance, the child omits verbs and some prepositions and changes the word order because of lacking the necessary knowledge about definite grammatical rules. There can be errors in using the endings of words in relation to plurals or possessive cases (â€Å"then I said yes and then not my friends and then they ask me to be their friends again†) (Chloe, personal communication, 2013). From this perspective, a child can formulate the phrase or sentence inappropriately according to their structure because of omitting some important details such as the word order of subjects and predicates. Thus, the child can say ‘sever’ instead of ‘civil’ or ‘paying’ instead of ‘playing’ as a result of confusing words (Chloe, personal communication, 2013). These errors are caused by the similarit ies in the words’ pronunciation, but they are not affected by the particular features of the other language in which the learner can be more competent. That is why, these errors can be discussed as developmental ones.Advertising Looking for research paper on linguistics? Let's see if we can help you! Get your first paper with 15% OFF Learn More When errors in the learner’s speech are caused by the first language background these errors are discussed and analyzed as transfer errors. The role of transfer errors is important to examine and assess the level of the language acquisition from the point of the first language’s impact on the process of learning the second language (Baker, 2007, p. 212). The child can make transfer errors when he or she is confused in relation to the two languages’ differences and similarities. Thus, it is typical for children to accentuate words according to the accent patterns which are characteristic for the first language’s structure and rules. It is also possible to pronounce words while learning the second language according to the known patterns which are frequently used in the first language. It is important to note that transfer errors are more closely connected with language mixing than with developmental errors because they are caused by the usage of the other language (Baker, 2007, p. 215). Language mixing along with transfer errors is characteristic for learners who speak those two languages which are similar in their nature, used principles, and rules as well as in the pronunciation of many words (Hartsuikerl, Pickering, Veltkamp, 2004). The phenomenon of language mixing is observed when a child uses both languages simultaneously because of spending much time within the environments where people speak two different languages (Heredial Altarriba, 2001). Living in the bilingual family, a child can mix languages in order to adapt to the situation and provide the nec essary word or phrase quickly and without concentrating on the language used (Hartsuikerl, Pickering, Veltkamp, 2004). There are a lot of concepts and notions which are operated in the family in one language in spite of the concrete situation of communication and language which can be used in relation to these definite circumstances (Greene, Pena, Bedore, 2013). Thus, the child can be inclined to mix languages while speaking about his or her family. For instance, grandmother and grandfather can be referred to as ‘Nana’ and ‘Tata’ because these concepts are frequently used in the family in order to speak about relatives as well as father can be called not ‘daddy’, but ‘papito’ (Chloe, personal communication, 2013). The first and second languages are mixed because these words are used while speaking in English. Language mixing is typical for young children because they do not analyze the fact of speaking two different languages, bu t children use the word which is more common for them, for instance, ‘Nana’ and ‘Tata’ instead of grandmother and grandfather.Advertising We will write a custom research paper sample on Second Language Acquisition specifically for you for only $16.05 $11/page Learn More The low percentage of developmental errors and language mixing indicates the good level of the second language acquisition. Thus, the frequent usage of such words as ‘Nana’, ‘Tata’, and ‘papito’ cannot be discussed as the influential factor to speak about the low level of the second language acquisition. However, the problems with structuring sentences and providing grammatical forms of words which can be analyzed as developmental errors are important to make conclusions about the level of learning the second language with references to learning and using its basic principles (Baker, 2007). Therefore, the degree of the second l anguage learning can be assessed by teachers with the help of examining the learner’s developmental and transfer errors and language mixing. Developmental errors are characteristic for the first stages of learning the second language when the key rules are learnt and skills are improved. The concepts of transfer errors and language mixing support the idea about the impact of the first language on the process of learning the second one. From this perspective, the situation of children’s language mixing can be discussed as more typical for bilingual families where both languages are learnt simultaneously. References Baker, C. (2007).
