these conventions as follows:  ¦ Bold indicates commands and keywords that are entered literally as shown. In actua l configuration examples and output (not general command syntax), bold indicates commands that are manually input by the user (such as a show command).  ¦ Italic indicates arguments for which you supply actual values.  ¦ Vertical bars (|) separate alternative, mutually exclusive elements.  ¦ Square brackets ([ ] ) indicate optional elements.  ¦ Braces ({ }) indicate a required choice.  ¦ Braces within brackets ([{ }] ) indicate a required choice within an optional element. xxix IntroductionRouters and Routing Basics CCNA 2 Labs and Study Guide is a supplement to your classroom and laboratory experience with the Cisco Networking Academy Program. Specifically, this book covers the second of four courses. To be successful in this course and achieve your CCNA certification, you should do everything possible to arm yourself with a variety of tools and training materials to support your learning efforts. This book is just such a collection of tools. Used to its fullest extent, i t can help you gain the knowledge as well as practice the skills associated with the content area of the CCNA 2 Routers and Routing Basics course.Specifically, this book can help you work on these main areas of CCNA 2:  ¦ Configuring a router  ¦ Managing the Cisco IOS  ¦ Selecting a routing protocol  ¦ Verifying and troubleshooting a network  ¦ Implementing basic security with access control lists Books similar to this one are also available for the other three courses: Networking Basics CCNA 1 Labs and Study Guide, Switching Basics and Intermediate Routing CCNA 3 Labs and Study Guide, and WAN Technologies CCNA 4 Labs and Study Guide. Goals and Methods One of the most important goals of this book is to help you prepare for either the CCNA exam (640-801) or the INTRO exam (640-821).Whether you are studying for the full exam or the first part of your CCNA, passing either of these exams means that you not only have the required knowledge of the technologies covered by the exa m, but that you can also plan, design, implement, operate, and troubleshoot these technologies. In other words, these exams are rigorously application-based. In fact, if you view the main objectives for the CCNA exam at http://www. cisco. com/go/certifications, you can see the following four categories of objectives:  ¦ Planning & Design  ¦ Implementation & Operation  ¦ Troubleshooting  ¦ TechnologyAlthough Technology is listed last, a CCNA student cannot possibly plan, design, implement, operate, and troubleshoot networks without first fully grasping the technology. So you must devote large amounts of time and effort in the Study Guide section of each chapter, learning the concepts and theories before applying them in the Lab Exercises. The Study Guide section offers exercises that help you learn the concepts and configurations that are crucial to your success as a CCNA exam candidate. Each chapter is slightly different and includes some or all of the following types of exe rcises:  ¦Vocabulary Matching and Completion  ¦ Skill-Building Activities and Scenarios  ¦ Configuration Scenarios  ¦ Concept Questions  ¦ Journal Entries  ¦ Internet Research xxx Routers and Routing Basics CCNA 2 Labs and Study Guide The Lab Exercises section includes a Command Reference table, all the online Curriculum Labs, and new Comprehensive Labs and Challenge Labs. The Curriculum Labs typically walk you through the configuration tasks step by step. The Comprehensive Labs include many, if not all, of the configuration tasks of the Curriculum Labs without actually providing you with the commands.The Challenge Labs take this a step further, often giving you only a general requirement that you must implement fully without the details of each small step. In other words, you must use the knowledge and skills you gained in the Curriculum Labs to successfully complete the Comprehensive and Challenge Labs. In fact, you should not attempt the Comprehensive or Challenge lab s until you have worked through all the Study Guide activities and the Curriculum Labs. Avoid the temptation to work through the Comprehensive and Challenge Labs by flipping back through the Curriculum Labs when you are unsure of a command.Do not try to short-change your CCNA training. You need a deep understanding of CCNA knowledge and skills to ultimately be successful on the CCNA exam. How This Book Is Organized Because the content of Routers and Routing Basics CCNA 2 Companion Guide and the online course is sequential, you should work through this book in order, beginning with Chapter 1. Chapters 1 through 11 cover the following topics: Chapter 1, â€Å"WANs and Routers†Ã¢â‚¬â€After presenting a few vocabulary exercises covering the topic of WANs, this chapter delves into the internal and external components of routers.Understanding how a router works and how you connect to a router are important concepts and skills you need throughout the rest of your CCNA studies. The three Curriculum Labs focus your attention on connecting LANs and WANs using routers. An additional Challenge Lab helps you review the skills learned in the Curriculum Labs. Chapter 2, â€Å"Introduction to Routers†Ã¢â‚¬â€This chapter discusses the basics of using the command-line interface (CLI).

Albert Jacka Soldier Man

Albert Jacka was born on the 10th of January 1893 in a small dairy farm in Winchelsea, Victoria. On the 17th of the first 1932, seven days after his 39th birthday, he died of chronic nephritis. He was the fourth child of 7 of Nathaniel Jacka and Mary Elizabeth Kettle. He spent most of his life in Wedderburn after his parents decided to move the family there in 1898 when Bertie was the age of 5. After completing elementary school, he found work as a labourer with his father, and later for the Victorian State Forests Department. On 18/8/14, Bert enlisted into the Aussie Imperial Force, assigned 14 Battalion, 4th Brigade, 1st Division and began training at Broadmeadow camp. Jackas battalion then left for further two months of training in Egypt. After that, his battalion then joined the fight in Gallipoli, arriving on Anzac Cove through the Dardanelles, 26/4/15. A month later on the 19th, the Turkish began an assault along almost the whole Anzac line, and captured a small twelve yard section of the trench, leaving one end being guarded by Jacka. For longer than several minutes, he shot warning shots into he trench until, finally reinforcements had arrived. Everybody but Jacka were hit so he leapt back into the communication trench. He had then thought up a new plan, two bombs would be thrown at the Turks, as Bert would walk around and flank them from behind. He shot five and bayoneted two as the others retreated. l managed to get the begars, Sir, he was quoted to have said to the first officer to arrive. For doing this act of courage, he was awarded with a Victorian Cross, which appeared in a section of the London Gazette. War Office, 24th July, 191 5 His Majesty the KING has been graciously pleased to award the Victoria Cross to the undermentioned Officers and Non-commissioned Officers:No. 65 Lance-corporal Albert Jacka, 14th Battalion, Australian Imperial Forces. For most conspicuous bravery on the night of the 19th-20th May, 191 5 at Courtneys Post, Gallipoli Peninsula. Lance-corporal Jacka, while holding a portion of our trench with four other men, was heavily attacked. When all except himself were killed or wounded, the trench was rushed and occupied by seven Turks. Lance-corporal Jacka at once most gallantly ttacked them single-handed, and killed the whole party, five by rifle fire and two with the bayonet. Albert was immediately known as a national hero. He began to be used on recruiting posters John Wren, gave him E500 and a golden watch, after promising the first Victorian Cross winner a reward of so. After the 28th of 8th he began to skyrocket from rank to rank, beginning with Corporal, then on the 12/9, Sergeant, then Company Sergeant Major on 14/11, and finally Second Lieutenant on the 29/4/16 after completing officer training. Early in June, the 14th Battalion were then sent to France. On the 7th of August, Berts platoon then moved into the line close to Pozi ©res, a small French village. One night after dawn, Just as Jacka had completed his surveying of the area, two German soldiers had overrun a part of line. They came to the entrance of Jackas dugout, rolling a bomb down the doorway, killing two men. Jacka survived, rushing up the steps, tiring as ne moved. He got up and came upon German soldiers rounding up about forty Aussies as prisoners. He spoke out to his platoon and charged against the enemy. Men threw away their rifles and began to participate n wild hand to hand combat, while the prisoners turned on their enslavers. On that night, they took capture of fifty Germans and retook back the line. Everyone was severely wounded, Jacka received serious neck and shoulder injures and was sent away to London hospital. On the 8th of the 8th, London newspapers sent out false reports claiming that Bert was killed in action. After this, Albert was promoted to captain and was authorised as the 14 Battalions Intelligence officer on the 15th March. Albert got back into the fght and led a night scouting party on the 8th of April, to inspect the enemys defences. He infiltrated the wire at two places, reported back, then he went out again to watch the laying of the guide tapes for the infantry. As the Job was almost done, two German soldiers creeped up, Jacka, realising that theyd see the tapes, he knew that they must be captured. He pulled out his pistol, misfired, so he rushed on towards them and captured them by hand. His smart, quick thinking, had saved the Anzac soldiers from discovery and possibly bombardment and had earnt himself a bar to his military cross. The newly captained Jacka, on the 8th July, was wounded by a snipers bullet near Ploegsteert Wood. Two months later on the 26th, he was back on his feet and back on the front, he led the 14th battalion against German Pillboxes(small underground outposts) at Polygon Wood. In March 1918, Jacka unknowingly faced his final fght, after being cruelly gassed at Villers-Bretonneux. A few months later, he boarded the Euripides, for Australia. A large crowd, including the Governor General, greeted him on his arrival in Melbourne. A few months after being discharged, R. O. Roxburgh, E. J. L. Edmonds and himself, created an electrical goods importing and exporting business. The following year on the 17th January, Jacka was hitched to Frances Veronica Carey, a typist at his Electrical Goods business. A few moths later, the moved to St Kilda and adopted a daughter. Eight years later, he was elected to the St Kilda Council and a year later elected as mayor. On the 18th of December 1931, he mysteriously fell ill during a council meeting and on January 17th, a year later, he died of chronic nephritis. Over 60,000 people paraded by his coffin as it lay in Anzac house. He was buried with complete military honor in the Presbyterian section of the cemetery.

Summary - Essay Example He stressed on necessity to separate Islam of the Prophet Mohammad which never teaches terror from Islam Kharijites. Mustafa Ceric said war against terrorism imply a war against Islam, because terrorists proclaimed they were acting on behalf of Muslims. Tim Sebastian asked Mustafa Ceric if there too much hatred preached within Muslim tradition. Mustafa Ceric answered that hatred should be stopped both from Muslims and non-Muslims sides. Ramzi E. Khoury said the war was about oil, therefore it’s â€Å"a godless war†. He doubted that current Western authorities are religious persons. Second part basically specified panelists’ opinions while answering audience’s questions.

Writing assignment - Article Example Although the betterment of the students undergoing through the programme can be observed, it will not be attributed to the programme alone as other factors can contribute to the exemplary performance. Students will gain advantage through the knowledge gained at high school while narrowing achievement gap will be through the creation of equity between students with different capabilities. Students’ high school experiences will be enriched through providing the students with a chance to enjoy academic programmes, enabling them to study with intensity, depth and better perspective (Challenge Success, 2013). The programme will be an indicator of quality in education thereby assessing the capacity of making schools better. The programme provides students with a myriad of opportunities while enabling them to take challenging courses in college. The impacts on the programme on the schools and students however, are difficult to substantiate. In seeking to gain maximum benefits from the programme, students should consider understanding their reasons for enrolling into the programme, by consideration of all elements involved. Educators on the other hand must consider the level of involvement which they would like from the programme, before implementing it into their institutions. This can be achieved through a discussion with the various stakeholders of the programme (Challenge Success, 2013). Challenge Success. (2013).

Elderly as a Vulnerable Population and the Effect of Healthcare on Research Paper

Elderly as a Vulnerable Population and the Effect of Healthcare on this Population - Research Paper Example Being elderly is one of the leading causes of vulnerability for which the health department of the US government has taken steps to research the vulnerable points of the elderly people to control their health-related problems. It can help nurses in giving holistic and all-inclusive attention if they are aware of the causes of elderly vulnerability (Ruof, 2002). Elderly Population’s Demographics The healthcare issues faced by the elderly need to be seen in the context of demographic changes and their effect on health and wellness. The next 5 years are critical in changing the demographics of the elderly population getting older (HHSS Strategic Plan, 2007). American population aging tenure has increased. A large number of people are above the age of 65 or older. A child born in 2006 can live till the age of 78, an increase of 10 years since 1965 when the Older Americans Act was enforced for Medicaid and Medicare. The population growth of older people increased doubly from 12 mil lion to 36 million from the total resident American population reaching 300 million from 150 million starting from 1950 till 2006. As per the estimates of the US Census Bureau, the older people’s population would increase as the first baby boomers turn 65 in 2011. By 2030, the elderly population would reach nearer to 20 percent of the US population. It creates serious repercussions and pressures on the healthcare system to meet the healthcare needs of the elderly, particularly related to chronic and severe health conditions and disabilities. The average American on the threshold of age 75 suffers from three chronic ailments and is prescribed five distinct medicines. There is huge dearth of such healthcare professionals attending to older Americans whose population would be increasing as anticipated to be 20 percent of the total American population (HHSS Strategic Plan, 2007). Stats indicate huge shortage of certified nursing assistants, home health aides, and personal care wo rkers whose requirement constitutes 874,000 to meet the demand in the coming 10 years while their supply would decrease to half by 2030 (HHSS Strategic Plan, 2007). Awareness Our behavior towards elderly could be biased. For example, when we hire a taxi to go somewhere and reach there in time, we may prefer young driver who, as is the stereotype assumption, take lesser time in driving to the location. In America, the population of aged licensed drivers is 30 million. If a driver’s age is less than 75, the possibility of accidents is less than if they cross the age of 75. It is because of their health issues such as dose intake or their reduced driving abilities, which could be risky. Sometimes, they are not aware of their reducing driving prowess and may argue otherwise. Some diseases such as dementia can cause cognitive blindness affecting the drivers’ acumen to identify their bad driving (Eldercare, 2010). Change in Outlook Research on the inabilities of the elder ha s changed the outlook on their issues. How an ordinary problem like heat can aggravate their worries is clear from the example of older peoples’ inability to cope with the heat outside. They are more prone to risk from heat-stroke. Old age becomes a hurdle in their ability to accustom to temperature change. They may have symptoms aggravated by heat and their medicines could give side-reaction to further aggravate their health condition (NIH News, July 18, 2011). Some of the factors

Human Resource Development and Consultancy Research Proposal

Human Resource Development and Consultancy - Research Proposal Example The model was chosen because it covers the SWOT analysis, A focus on the training on teams for fostering a more participatory organizational culture, Training programs for the HR group Promotion & recruitment within the company, Performance related pay (PRP) & Annual bonus which is related to company performance, Individual Development and feedback, and finally Performance Appraisals. These points were the recommendations made and roles presented of the needs of contemporary Human Resource Development in an organization. The recommendation was adapted from the work of existing scholars such as Kotter, and Gilbreath. The formulation and implementation of a successful corporate strategy for managing global operations according to Bartlett & Ghoshal (1992) and Beatty & Schneider (1997) requires a commensurate strategy for managing international human resources. Schuler et al. (1993) stipulated that, existing human resource frameworks describe policies and practices focused on aligning the strategic initiatives of the organisation and geared towards realizing some social goals of the enterprise. This situation will be complicated further with the current development of global managers while simultaneously managing the tension between integrating global operations and achieving local responsiveness (Schuler et al 1993). Henderson & Clockburn (1995), postulated that, organisations grow with their culture. As the activities of an organisation becomes more global so to should be the culture as the needs of the different stakeholders becomes diversify. Andrews (1997: p. 52) defines corporate strategy as â€Å"the pattern of decisions in a company that determines and reveals its objectives, purposes, or goals, produces the principal policies and plans for achieving those goals, and defines the range of business the company is to pursue, the kind of economic and human organisation it is or intends to be and the nature

The Ethical Standards of Nike Essay Example | Topics and Well Written Essays - 3000 words

The Ethical Standards of Nike - Essay Example Nike has changed its course of action in recent years from one of sheer denial and arguments to one of policy and change. The fact that the company responded only to global media pressure and the fact that standards only changed in Indonesia because of workers strikes and consumer pressure leave something to be desired about the ethical standards of Nike. However, it is important to recognize that Nike did change, though the implementation of the 1997 policies, almost ten years later, is not fully in effect. Â  Nike should be held ethically responsible for the working conditions in foreign factories of subcontractors. In a business decision, regardless of the international boundaries, it is important to follow a certain level of ethical standards. While it is impossible to judge if Nike absolutely knew of the sub-standard conditions, it is logical to assume that Nike could not have ignored the possibility, regardless of the information from Mr. Young, who said that the conditions were adequate in the factories. Yet, in countries where minimum age and working condition laws are not contusive to an appropriate and healthy lifestyle, Nike, by simple association, should maintain a level of dignity for their products. However, the legalities of the situation become more intricate for Nike, being an American based business, subcontracts to (mainly) Asian factories.
