Security Issues of Ambient Networks Essay -- Ambient Network Security,

In this essay we will present security issues of a networking concept referred to as ambient networks, which aims to enable the cooperation of heterogeneous networks belonging to different operator or technology domains. In this way, it appears as homogeneous to the users of the network services. Providing security in ambient networks is a huge challenge. The main reason is that the traditional security model is not valid anymore. Traditional security assumes that there is a vulnerable channel between communicating parties, where eavesdropping, modification of messages or denial of service attacks can occur. But it also assumes that the sender and receiver operate in some form of secure environment. Hence all models of attacks focus on the channel. Due to the distributed nature of ambient networks, the attack can be anywhere on the communication channels and on the devices. The attacker has the advantage that he can choose the easiest entry. I. INTRODUCTION Ambient network is the future network which refers to environment where we can communicate with anyone anywhere anytime. The current most emerging area of Ambient network is Ambient Intelligence.

“Growing Old” †a Poem by Matthew Arnold Essay

What is it to grow old? Is it to lose the glory of the form, The lustre of the eye? Is it for beauty to forego her wreath? Yes, but not for this alone. Is it to feel our strength Not our bloom only, but our strength decay? Is it to feel each limb Grow stiffer, every function less exact, Each nerve more weakly strung? Yes, this, and more! but not, Ah, ’tis not what in youth we dreamed ‘twould be! ‘Tis not to have our life Mellowed and softened as with sunset-glow, A golden day’s decline! ‘Tis not to see the world As from a height, with rapt prophetic eyes, And heart profoundly stirred; And weep, and feel the fulness of the past, The years that are no more! It is to spend long days And not once feel that we were ever young. It is to add, immured In the hot prison of the present, month To month with weary pain. It is to suffer this, And feel but half, and feebly, what we feel: Deep in our hidden heart Festers the dull remembrance of a change, But no emotion none. It is last stage of all When we are frozen up within, and quite The phantom of ourselves, To hear the world applaud the hollow ghost Which blamed the living man. Harneet Banga When we are younger we often imagine how great it would be to be older. However, when we are older, we can no longer enjoy life the way we used to, due to our physical body. Therefore the poem â€Å"Growing Old† by Matthew Arnold, basically interprets, that we should enjoy the present time we are given in life rather than looking forward to a time we think we’ll enjoy. Matthew Arnold has described the elderly people and the meaning of the poem, right through the poem, with the help of poetic devices. The specific idea of imagery of this poem appears to be related directly to the passage on old age people. For example, â€Å"Grow stiffer, every function less exact,† this quote states that once you’re older, the body of an old age person becomes stiffer, and they function less exact, this quotes states imagery because they describe how an old person feels and how their brain functions as well. In each stanza, Arnold has answered the question he posed in the first stanza which is, â€Å"What is it to grow old?† in each stanza that question is answered. Since the theme of this poem is about Old people, there are many symbols in this poem that describe the theme of the poem, and we could use this poetic device which is symbolism. The words such as, â€Å"old, wreath, last stage, stiffer, strength decay, etc† are words in the poem that symbolises growing old, basically symbolising the meaning of the poem. Simile is when you compare two nouns, and Arnold has used this device to explain how it feels to be old, â€Å"As from a height, with rapt prophetic eyes,† the words used in this example, have no common interest with one another, but it still demonstrates the meaning of the poem. Harneet Banga A dictionary definition of the word elderly will probably has something to do with mature and aged people, but the connation to describe the word elderly in the poem are, â€Å"Is it to lose the glory of the form,† or â€Å"The lustre of the eye† this is the connation version of describing the meaning of the poem, which are old people. This fantastic poem is missing one thing which would probably make this poem sound much better, which is the rhyming of the poem, it always lets people get into the poem, but unfortunately this wasn’t used in the poem. Since this poem doesn’t have a rhyme scheme, the meter of this poem is irregular; it doesn’t follow the â€Å"da Dum da Dum da Dum da Dum† style, it has come up with another original and unique style for the readers to figure out the meaning of the poem. Alliteration wasn’t common in this poem, let’s say it was hardly used; alliteration is having the same letter in one line couple o f times, â€Å"And feel but half, and feebly, what we feel:† Arnold uses this line in an alliteration way to describe how old age people feel, they basically feel in an extremely pathetically way. There are much more poetic devices used in this poem, assonance has a great impact on the poems meaning. Assonance is a repetition of the sound of vowel throughout the stanza, and in the poem they have repeated a vowel throughout a line in a stanza. For example, â€Å"Not our bloom only, but our strength decay?† the vowel â€Å"O† is used throughout this line of the poem, creating assonance and a meaning to the poem. The word old is being repeated constantly all through the poem, Arnold doesn’t say old in every stanza, but he does use similar words to describe old, and answers the question which he asked in the beginning of the poem, which is â€Å"What is it to grow old?† Matthew Arnold has described the meaning of the poem through all these poetic devices, for example the imagery is used in the poem to give us an image of an elderly person and how they feel. All these poetic devices have contributed to the poem in an extremely well manner, and with these poetic devices, the meaning of the poem became clearer.

Nursing Management Philosophy - 2422 Words

Nursing Management Philosophy Paper Laura Lindsey NURS_435 Lake Superior State University My Philosophy When developing a nursing leadership philosophy I must first look at why I want to become a nurse leader and reflect my philosophy upon my decisions to become a nurse leader. There are many reasons I want to be a nurse leader, but I am going only look at a few of those reasons. I always think there is room for improvement in nursing. When I say nursing, I am talking about all four of constructs of nursing (person, environment, health, and nursing) of the meta-paradigm. I want to be a leader in nursing because as a nurse leader I have the ability to help others get better, physically, emotionally, and mentally.†¦show more content†¦Thus they are stuck at level four and will not be able to move forward. Health is related not only to physical illness but mental and spiritual illness as well. It can be the absence or present of an illness. Health is what the nursing construct identifies and improves. Nurse leaders help an individual with maintaining a well develop construct of themselves. The staff member must be willing to adapt to better their patient care. Roy (2010) â€Å"†¦ concept of health is related to the concept of adaptation and the idea that adaptive responses promote integrity,† (p.173). In the nursing meta-paradigm, I have nursing left to discuss. Nursing does not have to be necessarily a â€Å"nurse† helping a â€Å"patient.† Nursing is when any one person or group helps another individual get better.. The nurse is there to help the patient learn about their illness and educate them so they can make educated decisions about their own care. According to King (2010) the nurse’s goal is to recover health and to preserve individual’s health (p. 150). Nurses are the advocates for the patient; they must have respect for the patient, and keep the patient safe. Potter and Perry (2009) the ANA Code of Ethics for nursing states that the nurse is there to â€Å"†¦.. promote, advocate, and st rive to protect the health, safety and right of the patient,† (p.315). It is not the nurse’s job to judge the patient. The nurse is only there to assess and educate the patient.
