Network – A network database model helps to allow different records to be linked to the same owner file. This is usually looked upon as an upside down tree which make it look as if it is linking up to the owner bit that is at the bottom of the tree. This helps to make it look flexible. Also the relationship within the database model can be seen as a many-to-many relationship, which means it can be linked to many different file etc. Advantages: There are some advantages and disadvantages to this model, the advantage of this is that it is more capable of handling the different amount relationships within which include the one to one and many to many relationships. It is much easier access than a hierarchical model, and the data is more independent. (Easy2teacH) Disadvantages: Although there are some disadvantages as when one of the structures changes then there will be a lack of independence within the structures as it is compulsory to change the application. And the records must be maintained by using the pointers which in turn makes it more complex.

Literary Devices In Shakespearan Sonnet - 958 Words

I chose to admire â€Å"Shakespearean Sonnet†, because I enjoy reading Shakespeare although sometimes I have a difficult time understanding it. I find the poem to be unique, just by the way it was coordinated together. It basically is lines from each of Shakespeare’s famous plays of all time. The lines from the well-known plays was combined to form a sonnet of 14 lines using the ababa format. Throughout the poem you can find the use of a couplet in a couple of the poem’s lines.. It is very well written and excellent in ways like how it describes each of the plays in the lines of the sonnet, to the imagery, tone, and theme of the poem. The use of alliteration for example, in line 2, â€Å"Boy meets girl while feuding families fight,† is a description†¦show more content†¦Also, it shows that the author uses humor while broaching issues of today’s modern society. This poem is basically just saying that today’s society should learn a thi ng or two about the writers of yesterday, and how they use time and patience to get their poems, stories, and plays done, without the use of worry of fear of deadlines or time it must be turned in or completed. This poem has very good strengths and the excellence of the poem is that is basing the issue that people should take their time when they are writing a story, poem, short story, or play. The author is basically saying that if we take our time to do things, then we don’t have to repeat it over and repeatedly. If we get it done correctly once then we don’t have to worry about it after we are finished. I like how the author describes all the different plays written by the man Shakespeare himself. People like William Shakespeare took time to process his plays, sonnets, and poems till he feels or know that it is ready and done to show the world of his greatness. We all need to look at this and do what the author says. We all need to not rush, but take our time when d oing and assignment, a paper, or even a test. Nowadays we see time as the enemy instead of an ally. We rush into doing things without looking over or correcting our mistakes, and when we don’t do that and turn in our work as it is, and get it wrong we blame others

Effects On Sexual Relationship Health And Social Care Essay Free Essays

Globally human life is exposed to a premier threat of deathly HIV virus which have halted 35 million people to decease and 34 million were populating with HIV boulder clay 2011 HWO study, 2013. In the recent epoch, augmented figure of I.V drug users, insecure blood transfusion and multiple sex spouses are considered high hazards for HIV transmittal, on the contrary fright of stigmatisation, deficiency of credence in the community and effects on sexual relationship are some critical factors which hinder revelation of HIV position and advance rapid spreading of HIV among vulnerable people. We will write a custom essay sample on Effects On Sexual Relationship Health And Social Care Essay or any similar topic only for you Order Now Continuing the secretiveness of HIV position means endangering others life. Should the infected hazard the life of others? I assert that unwraping HIV positive position to sexual spouses and household will diminish hazard of HIV transmittal, better entree to medical intervention and increased chances of societal and moral support for the patient. Advocates argue that the foremost of import benefit of unwraping HIV position to sexual spouse and household is to cut down the hazard of HIV transmittal. Although to make up one’s mind when, to whom and how to portion the dismaying HIV positive position is hard but after the revelation sexual spouses and household members become watchful to cognize their ain HIV position. To command HIV epidemics Voluntary HIV proving and reding ( VCT ) can efficaciously cut down hazard behaviours among persons vulnerable to HIV ( WHO, 2004 ) . This is non plenty to cognize about HIV position but sharing it with sexual spouse reduces associated emphasis and alteration in behaviour. Sexual spouse become interested to cognize the different path of HIV transmittal to follow preventative schemes. Up till now despite of the singular promotion in the field of medicine no vaccinums are available for HIV. However the lone defensive tool is to affect the vulnerable population in precautional behaviour s. Research based literatures have concluded that after unwraping HIV position the most frequent preventative behaviour followed by testing is addition in the usage of rubbers ( Lauretta et al, 2010 ) . Furthermore, in the survey of Niccolai, Dorst, Myer, A ; Kissinger ( 1999, as cited in Lauretta et Al, 2010 ) it was concluded that the usage of rubber among those who have n’t unwrap their HIV position to sexual spouse was about 23 % while 73 % of sample who have disclosed their position to sexual spouse were consistent to condom usage. The above given literature evident the positive result of HIV position that supports the statement of advocates that Unwraping HIV diagnosing limits the transmittal of infection. The advocates besides claim that unwraping HIV increase the inclination towards better intervention chances. Normally in our ain cultural context after sharing any dismaying diagnosing non merely patient itself but customarily the patient close relations remain in battle to place such centre where there is easy handiness and cost effectual intervention. Furthermore others shared their experiences and battles and seems helpful in designation of different agencies to acquire rid of the disease. During my clinical rotary motion I have encountered two HIV positive immature age patients. The parents of both patients knew the diagnosing and the male parent of one patient despite of limited income shifted his boy to Aga khan university infirmary for quality intervention. Certain intervention like HAART therapy if received in initial phase can cut down the lay waste toing consequence of HIV virus. HAART therapy decreases the patterned advance of HIV to AIDS by 86 % ( sterne, 2005 ) . Early d esignation, early revelation and early entree to intervention are good for the better forecast of any disease. Instrumental, informational, emotional and fiscal advantages can be achieved to better entree to medicine through unwraping HIV position to supportive web ( Waddell A ; Messeri, 2006 ) . In the survey of Waddell A ; Messeri ( 2006 ) it was concluded that those who did non concealed their HIV positive position from any family member the average odds of intervention was 0.64 with a high support comparison to those who did non unwrap their Status the average odds of intervention was 0.21. Different researches have been conducted to happen out the effectivity of HIV forecast and function of ART Harmonizing to Oppenheim. ( 2009 ) † about 80 % of patients are now alive 10 old ages after sero-conversion † . HIV virus targets the immune system specifically on CD4 cells ( type of immune cell ) finally reduces the defensive ability of the organic structure and the rate of timeserving infection like Tuberculosis ( TB ) increases. Preventing the patient signifier these timeserving infection can better life quality of HIV persons. In 2010 among 34 million instances of HIV worldwide 1.1 million instances in sub-Saharan Africa were estimated holding HIV related TB ( Suthar et al. 2010 ) . To command the overpowering effects of HIV /AIDS revelation make it possible to entree the support commissions. There are different organisations in the universe which are working for bettering the life criterion of HIV patients for illustration Alaskan AIDS Assistance Association ( 2008 ) supply aid to 300 HIV single yearly in the signifier of money, medicine, supplying occupations, lodging, and instruction in Alaska ( USA ) . Unwraping HIV position seems helpful to acquire societal and emotional support from household. Not unwraping one ‘s HIV position is striping patient from psychological support which is possible to be achieved through revelation. Family members, friends and equal group become more sort, and credence is increased. Disclosure of HIV position to household or sexual spouse strengthen interpersonal relationship which reduces the emphasis related to the diagnosing either to unwrap or non, and every clip HIV patients think about credence in the community, rejection from the household and spouse, stigmatisation and favoritism if the people came to cognize approximately positive position. This lead towards societal isolation and finally produces bad impacts like emphasis, depression, related to maintaining the diagnosing in secrete. Harmonizing to WHO ( 2004 ) â€Å" revelation of HIV diagnosing increases societal support, credence, kindness and edifice relationship of trust among house hold members and septic individual † . These positive attacks from the household non merely cut down stress degree but besides due to the instrumental support from the household patient feels that he/she can stay in the society like others which increases their degree of self-esteem. The important others of the HIV positive patient facilitate induction and attachment to HIV intervention. Harmonizing to amy Norman ( 2006 ) Disclosure of HIV position can enable the activation of household or community support web and cut down the morbidity through better psychological direction, moreover revelation go an entry standard for many intervention plans and is important to adhere with intervention. Oppositions argue that HIV position of patient should non be disclosed because unwraping the diagnosing consequences in stigmatisation and patients feel the fright of rejection in household and community. Furthermore oppositions besides claims HIV positive patients are discriminated in the s ociety, their rights of confidentiality are violated and revelation to sexual spouse affects sexual relationship. Due to the mentioned grounds oppositions are support to maintain the diagnosing in secretiveness. Protecting others from catching disease is ethical and moral duty of every person. To diminish the opposition and increase credence of HIV positive patient, cumulative attempt are needed to convey a drastic alteration in the perceptual experience of people through verbally pass oning emotions and concerns. As a nurse it ‘s our premier duty to aware the people about HIV and alter the perceptual experience of people about HIV persons. I believe that maintaining HIV diagnosing in secrete will do its revelation more dismaying while increase figure of revelation will consequences alter in perceptual experience and the phobic disorder of the disease will be decreased. Once the position is shared with the sexual spouse does non intend that sexual activities can non be continued any longer. There are alternate preventative steps like usage of rubbers and serosorting to forestall the hazard of transmittal. In a peculiar survey HIV positive drug users after sharing their position with th eir sexual spouses were experiencing more comfy and relax with a lower anxiousness degree about transmittal ( Julianne, Daniel, Sarah A ; Tinal 2005 ) . Evidences exist that reding can assist to increase the frequence of revelation to sexual spouse. The consequence of guidance can be evaluated from a cohort surveies with the result of 56-65 % revelation rate among those who attended six reding session comparison to those who attended three Sessionss and did non unwrap their position. ( Scaly et al 2012 ) . I will reason with the statement that it is more good to unwrap the HIV position of patient to cut down the hazard of transmittal, to hold a better entree to intervention, and to acquire more moral and societal support from household comparison to its disadvantages.

Relationship Formation - The Filter Model free essay sample

The Filter Model:This model states that relationships go through three filters.These filters can be remembered as DAN. Demographic, Attitudes, and Needs.Before we begin filtering we look to the Field of Available. This includes all the people we could possibly have a relationship with.The first filter is then Socio-Demographic Variables. Such variables include similar background, education, location etc. People with different or incompatible variables are filtered out at this point.The second filter is Similar Attitudes. Similar attitudes help aid communication and so the more attitudes, beliefs, and ideas the couple share the more likely they are to form and sustain a relationship. People with different or incompatible attitudes are filtered out at this point. The third filter is Complimentary Needs. Once the relationship is established, complimenting each others needs becomes one of the most important factors. To study the model, Kerkoff and Davies conducted a study using students in a relationship for 18 months. We will write a custom essay sample on Relationship Formation The Filter Model or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Using self-report questionnaires, the study found that attitude similarity was the most important factor for up to 18 months, were complimenting each others needs becomes the most important factor.The study used real-life couples and so has an aspect of mundane realism.However, there are problems with this study. Firstly, self-report questionnaires are problematic as they are easy to lie on, or to misrepresent data, or to get wrong as they often require retrospective knowledge. This means that the findings could be biased or incorrect. People may also show social-desirability bias, in order to paint their personal relationships in a better light. The study does support the filter model by showing that there are stages to a relationship and that these stages have distinct markers. However, this model is flawed. The socio-demographic variables stage may not be as important as the model makes out, with the rise in internet dating and also long-distance relationships, especially in military families, not fitting in with the model.However, Sprecher conducted another study and found that couple matched in physical attractiveness, social background, and interests were more likely to develop a long-term relationship. This suggests that the filter model is correct in regards to socio-demographic variables. The filter model also fails to explain a lot of individual differences, so this could account for the difference in socio-demographic variables. It also disregards outside influence, social desirability, and it is assumed to be an unconscious choice to enter a relationship with a certain person. This removes a certain amount of the romantic aspect of relationships, rather showing it to be more about convenience and benefit than any sort of loving relationship. Many of the theories in this area seem to box off human emotions and prove to be robotic in nature; human emotions and relationships are often more fluid and complex than this area perceives.
