Leading in the Darkness and the Light - Essay Example Question Two: The trapped miners gave maps to the rescue team. Members of the team stepped up as leaders to help manage the situation in the mines. They displayed transformational leadership through various acts. Mario Gomez, who was the oldest miner, took the responsibility of ensuring that catering for everyone’s mental and spiritual health. Another miner took the role of ensuring that the physical health of the crew was intact. The miners ensured that they took care of the whole person, meaning that the trapped miners were cared for mentally, spiritually, emotionally and spiritually. The miners worked together in shifts of their groups. The miners who had leadership roles also were willing to and did their best to serve others who needed help like the trapped miners by providing both physical and physiological help. The trapped miners had chosen a person who uplifted their humor, and another was named the pastor of the group who uplifted their spiritual moods. This displayed authentic leadership in times of adversity. They showed that they had hoped for life by ensuring that they organized all their activities while trapped to ensure their survival. Question Three: The president displayed a truly transformational leadership by responding quickly to the situation. Even though there were low, the chances of survival the president went ahead and organized, how they would be rescued by having the vision and choosing people to deal with the rescue. The Mining Minister had a team that was divided into three teams with different tasks. One was to locate the miners; the other was tasked with keeping them alive, and the other ensuring that they are rescued safely. All the three leaders displayed servant leadership, as they were willing to serve others before their needs.

A critical analysis of article-3 of the European Convention on Human Dissertation

A critical analysis of article-3 of the European Convention on Human Rights - Dissertation Example Every human being needs the fundamental rights as a primary requirement in their life,which feciliates them with security to live their life in present day world.The basis of this right is the respect to the human values by securing the human rights. The basis of this right is the respect to the human values by securing the human rights. On the contrary, ECHR is all set to work for the protection of human rights in th european countries. However, some of its policies regarding certain humain rights are still not worth effective. As, Article 3 of the European Convention on Human Rights, prohibits torture â€Å"inhuman or degrading treatment or punishment†. In other words we can say any intentional act by which severe pain or suffering is caused physically or mentally to a person. The definition has tried to cover a huge objective scope, rather than becoming subjective and more definite. Resultantly, due to its infinite nature, the Article 3 has been a critical issue. There is a lack of exact definition and clear meaning of torture mentioned in the article. Nevertheless, torture has a wide range, from normal torture to severe punishment and that may vary in different age group. But, Article 3 does not seem to cover all the aspects of human rights. Initially the UK Court had restrictive view on what consisted of torture, preferring to find that states had inflicted inhuman and degrading treatment. Though ECHR is fighting for the rights of children and protect the children from violations but the criteria it has designed is not able to act effectively. Thus the court held that practices such as sleep deprivation, subjecting individual to intense noise and requiring them to stand against a wall with their limbs outstretched for extended periods of time, did not constitute torture1. On the contrary, there is a necessity of giving more emphasis on the rights of the children, because they are the usual victim of torture and prohibitions, which deprive them of th e human rights in their normal day to day life. That may lead to troublesome life of the children. In such case, the convention’s Article 3 seems to be insufficient to provide protection to the children in an authentic way. Keeping in view, the importance of child’s right The United Nations Convention on the Human Rights of the Child defines a child as a human being below the age of 18 years unless under the law applicable to the child, majority is attained earlier, 2 agreed by 192 of 194 member countries. Biologically, a child is anyone between birth and puberty or in the developmental stage of childhood, between infancy and adulthood. Children generally have fewer rights than adults and are classed as not able to make serious decisions, and legally must always be under the care of a responsible adult.3 The positive side of European Convention on Human Rights is their step towards the reforms in human rights and possibly, there are chances of more amendments and impro vement in the capacity of the policies; enabling them to protect the children from any kind of abuses. Due to the lack of contents in the Article 3 of European Convention, The UK Court has emphasized the fundamental nature of Article 3 in holding that the prohibition is made in absolute terms, irrespective of a victim's conduct. The Court has also held that states cannot deport or extradite individuals who might be subjected to torture, inhuman or degrading treatment or punishment, in the recipient state.4 If we look at the history of torture, it was first used in the ancient Greeks and Romans for interrogations. Torture was used only on slaves until the 2nd century. But, gradually that started spreading to all the sections in lower class people. Statement of a slave was valid, only if it has come out through torture.5 But at the present scenario when we talk about child torture and their right it would be important to find the definition of torture and its relevance with child†™s right. Torture, according to the United Nations

Types Of Magnetic Storage Devices Computer Science Essay

Types Of Magnetic Storage Devices Computer Science Essay Magnetic storage devices are used to store data in magnetic medium. In this term paper we will discuss about its types and working principle. The main logic is that the data will secure in these storage devices and data will store quickly in these devices. In this term paper we will also discuss the future of these devices. MAGNETIC STORAGE DEVICES Magnetic storage and magnetic recording are terms from engineering referring to the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetization in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads. As of 2009, magnetic storage media primarily hard disks are widely used to store computer data as well as audio and video signals. HISTORY Before there was magnetic storage for computers, the primary storage medium was punch cards (paper cards with holes punched in to indicate character or binary data) originally invented in the 1890. Although long obsolete in computer use punch cards in various forms are still used in older voting equipment. PUNCH CARD The history of magnetic storage dates back to June 1949 when a group of IBM engineers and scientists began working on a new storage device. What they were working on was the first magnetic storage device for computers, and it revolutionized the industry. On May 21, 1952 IBM announced the IBM 726 Tape Unit with the IBM701 Defense Calculator, marking the transition from punched-card calculators to electronic computers. Four years later, on September 13, 1956 a small team of IBM engineers in San Jose, California, introduced the first computer disk storage system as part of the 305 RAMAC (Random Access Method of Accounting and Control) computers. IBM 305 RAMAC The 305 RAMAC drive could store only 5MB of data on 50 disks each a whopping 24 in diameter. Unlike tape drives RAMACs recording heads could go directly to any location on a disk surface without reading all the information in between. This random accessibility had a profound effect on computer performance at the time enabling data to be stored and retrieved significantly faster than if it were on tape. From these beginnings, the magnetic storage industry has progressed such that today you can store 500GB or more on tiny 3 1/2 drives that fit into a single computer drive bay. IBMs contributions to the history and development of magnetic storage are incredible. Not only did IBM invent computer magnetic tape storage as well as the hard disk drive but it also invented the floppy drive. The first floppy drive was created in 1971. EXAMPLES OF MAGNETIC STORAGE DEVICES HARD DRIVE FLOPPY DRIVE Mini DV TAPE DATA TAPE BACKUP STRIPE ON THE BACK OF DEBIT.CREDIT CARD MAGNETIC RECORDING Magnetic recording is the method of writing data on disk. ANALOG RECORDING Analog recording is based on the fact that remnant magnetization of a given material depends on the magnitude of the applied field. The magnetic material is normally in the form of tape, with the tape in its blank form being initially demagnetized. When recording the tape runs at a constant speed. The writing head magnetizes the tape with current proportional to the signal. A magnetization distribution is achieved along the magnetic tape. Finally the distribution of the magnetization can be read out reproducing the original signal. The magnetic tape is typically made by embedding magnetic particles in a plastic binder on polyester film tape. The commonly used magnetic particles are Iron oxide particles or Chromium oxide and metal particles with size of 0.5 micrometers. Analog recording was very popular in audio and video recording. In the past 20 years, however, tape recording has been gradually replaced by digital recording. DIGITAL RECORDING Instead of creating a magnetization distribution in analog recording, digital recording only need two stable magnetic states, which are the +Ms and -Ms on the hysteresis loop. Examples of digital recording are floppy disks and HDDs. Digital recording is the main process nowadays and probably in the coming future. HARD DISK DRIVE A hard disk drive is a non-volatile storage device that stores digitally encoded data on rapidly rotating rigid (i.e. hard) platters with magnetic surfaces. WORKING A hard disk uses rigid rotating platters. Each platter has a planar magnetic surface on which digital data may be stored. Information is written to the disk by transmitting an electromagnetic flux through a read-write head that is very close to a magnetic material, which in turn changes its polarization due to the flux. A typical hard disk drive design consists of a central axis or spindle upon which the platters spin at a constant rotational velocity. The associated electronics control the movement of the read-write armature and the rotation of the disk and perform reads and writes on demand from the disk controller. The sealed enclosure protects the drive internals from dust, condensation, and other sources of contamination. Contrary to popular belief, a hard disk drive does not contain a vacuum. Instead, the system relies on air pressure inside the drive to support the heads at their proper flying height while the disk is in motion. FLOPPY DRIVE A floppy disk is a data storage medium that is composed of a disk of thin, flexible magnetic storage medium encased in a square/rectangular plastic shell. WORKING The following is an overview of how a floppy disk drive writes data to a floppy disk. Reading data is very similar. The computer program passes an instruction to the computer hardware to write a data file on a floppy disk, which is very similar to a single platter in a hard disk drive except that it is spinning much slower, with far less capacity and slower access time. The computer hardware and the floppy-disk-drive controller start the motor in the diskette drive to spin the floppy disk. The disk has many concentric tracks on each side. Each track is divided into smaller segments called sectors, like slices of a pie. A second motor, called a stepper motor, rotates a worm-gear shaft (a miniature version of the worm gear in a bench-top vise) in minute increments that match the spacing between tracks. The time it takes to get to the correct track is called access time. This stepping action (partial revolutions) of the stepper motor moves the read/write heads like the jaws of a bench-top vise. The floppy-disk-drive electronics know how many steps the motor has to turn to move the read/write heads to the correct track. The read/write heads stop at the track. The read head checks the prewritten address on the formatted diskette to be sure it is using the correct side of the diskette and is at the proper track. This operation is very similar to the way a record player automatically goes to a certain groove on a vinyl record. Before the data from the program is written to the diskette, an erase coil (on the same read/write head assembly) is energized to clear a wide, clean slate sector prior to writing the sector data with the write head. The erased sector is wider than the written sector this way, no signals from sectors in adjacent tracks will interfere with the sector in the track being written. The energized write head puts data on the diskette by magnetizing minute, iron, bar-magnet particles embedded in the diskette surface, very similar to the technology used in the mag stripe on the back of a credit card.The magnetized particles have their north and south poles oriented in such a way that their pattern may be detected and read on a subsequent read operation. The diskette stops spinning. The floppy disk drive waits for the next command. FUTURE Magnetoresestive Random Access Memory A new type of magnetic storage, called Magnetoresistive Random Access Memory or MRAM, is being produced that stores data in magnetic bits based on the TMR (Tunnel Magneto resistance) effect. Its advantage is non-volatility, low power usage, and good shock robustness. WORKING Unlike conventional RAM chip technologies in MRAM data is not stored as electric charge or current flows, but by magnetic storage elements. The elements are formed from two ferromagnetic plates, each of which can hold a magnetic field separated by a thin insulating layer. One of the two plates is a permanent magnet set to a particular polarity the others field can be changed to match that of an external field to store memory. This configuration is known as a spin valve and is the simplest structure for a MRAM bit. A memory device is built from a grid of such cells. The simplest method of reading is accomplished by measuring the electrical resistance of the cell. A particular cell is (typically) selected by powering an associated transistor which switches current from a supply line through the cell to ground. Due to the magnetic tunnel effect the electrical resistance of the cell changes due to the orientation of the fields in the two plates. By measuring the resulting current, the resistance inside any particular cell can be determined, and from this the polarity of the writable plate. Typically if the two plates have the same polarity this is considered to mean 1, while if the two plates are of opposite polarity the resistance will be higher and this means 0.

AIDS/HIV Research :: essays research papers

AIDS Research All A.I.D.S research should be funded by the government. Today A.I.D.S has become a large concern within society. Sexually active youth are constantly threatened with the chance of getting A.I.D.S.. A.I.D.S is everyone's problem and a cure has to be found. With funding from the government, it will provide the capital necessary for the research to find a cure, to stop the spread of A.I.D.S; eventually bringing down the number of people contracting and spreading the disease. Presently, many people have contracted the A.I.D.S virus, and it has become close to an epidemic. People who are sexually active have this constant threat of the disease looming over their heads. The people that contract the disease are normal people just like you and I. This disease does not favor any race or sexual preference. Many more people than you might believe have this disease, and the thing is many of these people, don't even know that they have the virus. Although many people may consider A.I.D.S research as costly and ineffective it is extremely important as a cure is found. Research requires a lot of funding whether it be private or government funding. This money is exceptionally important, as it provides the equipment, and the peoples salary who are doing the research. The amount of money needed for the research may seem like it is a lot, but it is worth it. It is worth it because if you consider the amount of money that we give to foreign countries to aid their economy we could be using this money to save peoples lives all around the world. People are dieing everyday, and many more are in hospitals; so if we find the cure we will save lives, and get these people who have contracted the disease out of hospitals, and living on their own again. Furthermore, research to stop the spread of A.I.D.S must be done. Meanwhile, in the search for a cure, research has to be done to find better methods of stopping the spread of the disease.

An Overview Of Collaboration Procurement Construction Essay

Procurement is a term which describes the activities undertaken by a client or employer who is demanding to convey about the building or renovation of a edifice. Procurement has great influence on the clip, cost and quality. The made-to-order nature of many building undertakings increases the built-in hazards. These hazards include finishing a undertaking which does non run into demands, which is delivered late or costs more than the client can pay or fund. All these hazards can impact the client ‘s nucleus concern, earnestly. The procurance scheme developed balance hazards against undertaking aims at an early phase of building. This method of procurance involves the contractor being responsible for design every bit good as building, it can be suited for all clients, including inexperient clients and those necessitating distance from the undertaking and cost certainty and faster path. It is of import at the beginning to guarantee that the field of treatment is clearly defined. One of the jobs that have beset this peculiar country of building research is a deficiency of clear definition. ( rowlison, steve ) As procurance the undertaking squad will be selected. After the undertaking squad has been selected the undertaking can come on through developing initial design work to fixing drawings and paperss to exemplify the undertaking, accomplishing be aftering consent, specifying criterions to be met and apportioning duties. During this period the client ( or undertaking patron or undertaking director ) should guarantee land purchase is completed on clip, if necessary guarantee the design procedure is consistent with the strategic brief, guarantee an internal decision-making system is in topographic point to avoid design holds. Keep the wider client organisation informed set up. An appropriate support model to guarantee payments can be made on clip. Construction stage will come on under the direction of the undertaking director or the undertaking squad. ( online ) Collaborative procurance is non popular but this method is increasing in the worldwide. Collaborative procurance is seen as horizontal coaction between different local governments during one or more stairss in the procurance procedure. In this method contact is made with different little companies with the regard of their forte. Through this procedure many companies take complete equipment and make their ain undertaking. Different advantages can be gained by collaborative procurance in footings of effectivity and efficiency. In this signifier the rate of success depend on the manner of organisation which is used. The collaborative procurance proposals are the manner to utilize the professional purchasing organisation by puting up a different companies in one panel and it drive to greater coordination, consistence and transparence. ( Online ) Partnership may hold somewhat different contents and range so coaction, but the lowest common is that the parties will work as a group jointly in any regard and that the parties must hold assurance in each other. The term collaborative contract, a definition of a collaborative contract is to be controlled by client and contractor and it is besides modulate the regular interaction between the client and a contractor. It besides makes the regular contact with contractor and adviser of different undertakings. Therefore the Collaboration procurance is really of import for multi undertakings. This client will salvage the clip and cost. Quality will besides better by doing contract with all specializers in their ain Fieldss.Method statementIntroductionNahar al-wafa Est. has the expertness and resources to transport out this developing undertaking and welcoming the chance of fall ining the professional squad during pre-tender phase.

Global Access Control Case Study Essay

With business always changing and data always needing to be protected, it has become an issue to determine the level of security for confidentiality and integrity purposes while allowing it all to be properly available for use. To put Global in front of the competition with its customers it implements its Global Connect-Link for collaboration. Through the use of its security division, CIS, Global prioritizes its data according to the risk of activity of usage against the potential business reward. It conducts constant supervision and monitoring to maintain confidentiality, integrity and availability. Global also has its own Continuity Manager software to manage large amounts of external users while maintaining the necessary centralized security from unauthorized access. Another level of security Global offers is its DLP or data loss prevention product. This keeps all data whether structured or unstructured when in motion or at rest from being compromised and deleted. Lastly in regards to Global’s controls and the documentation of the effectiveness of these controls, CompScan, an audit program is in place to collect and analyze all the data. The overall analysis of Global is that they seem to have a good grasp on keeping all data protected for confidentiality purposes, allows for the transferring of the data to be done securely for integrity purposes and gives it customers, partners, employees and suppliers proper access to all data based on privileges for availability purposes. The only weakness that may exist is the proper training for its employees on all that Global offers. With such incredible software support and ability to provide security without worry it will have to maintain constant training to make sure that simple human error doesn’t become an issue but if something were to happen then the proper steps are taken and followed to avoid corruption from taking place. When it comes to the reporting of is financial data certai n policies and procedures must be followed accurately. With an insecure system the opportunity of having inaccurate financial data reported is a good likelihood. Federal laws require that financial data of any sort be kept private and secure at all times whether at rest on the network or in transit when being viewed or sent to a fellow business entity. The use of the security division’s IRM or information risk management has had a great influence on its ability to  maintain business and get the edge on its competitors. The use of its Connect-Link, its prioritizing of security on investments, its Continuity Manager, its data loss prevention product and its CompScan it’s easy to see why peace of mind is something that is Global can offer at a 95% success rate. To solve the internal problems like employee training, Global can hire a outside company to come in on a basis determined by the security division and conduct classes to make sure all employees are up to date on proper procedures and understanding of keeping security at the top of their own priority list. Maintaining good training programs minimizes the risk of user errors but doesn’t completely eliminate them. Adding other security like anti-virus software to the workstations and closing off ports that are not in use on a regular basis will also help ensure a higher percentage of user compliance to following the rules and policies in place.
