Project management - sports pavillion at St. George's College Essay

Project management - sports pavillion at St. George's College - Essay Example PART A INTRODUCTION The project understudy is the construction work to extend and alter the sports pavilion at St George’s College and development of accommodation for Warden in and committee room. This project is taken as the critical opportunity mainly for the following reasons: The college is situated within densely populated area within city; hence, there is high risk associated with the construction work to be completed within defined frame. On-time completion is also critical as work is scheduled within holiday season. Project has high social value for the being provision of services to college. Successful accomplishment of the project is linked with the projects of two more schools. Hence, the project is taken with more responsibility orientation with client’s defined framework of task to be accomplished within time (most important), cost, quality and risk. PROCUREMENT ROUTES The procurement of the project is guided by three possible options which are as follows (Curtin University of Technology, n.d.): Traditional Approach Design and Construct Management Fee Each of the mechanism carries suitability for some while costing other. For the under study project; it is suggestible for the client to adopt the procurement route of Design and Construct with complete package by supplier variant. Design and construct entails hiring of the consulting firm (project manager) that develops design for the client’s requirement and further hires contractor for the construction services. It will facilitate client with a single point of contact as the management intend to have least involvement in overall construction process. It is also suitable for the college management based on their specification mentioned. Discussed below is the evaluation of the mechanism with respect to set criteria: Time: Fast tracked as the design and the construction can be carried in parallel. It also ensures the completion of the project on date which is very critical in th e case understudy. Cost: It also provides accurate estimate of the cost. Quality: This method is since not as quality oriented as management fee method but ensure quality construction according to the defined needs of required construction. Risk: aligned with the need of the college management, this method also carries minimum risk on part of employer and almost all risk is born by contractor. Given below is the reflection of methods and associated risk: (Curtin University of Technology, n.d.) Hence, the procurement method of design and construct can be justified as the most suiting method to the need of college management with facilitating of a single contractual firm that integrates design and construction expertise and accountability resting within one firm. RISK MANEGEMENT Success of the project is not only dependent on the accuracy of planning but is also dependent on level of consideration given to risk management. Simple to state, risk is the probability of not achieving the stated goal, since single aim of every objective is to accomplish it successfully; hence it requires projects to identify, analyse, asses and manage likelihood and impact

Culture and Family in Nursing Essay Example | Topics and Well Written Essays - 1750 words

Culture and Family in Nursing - Essay Example A vital objective for health care providers, as for instance, is established in the increasing acknowledgment of the family's value to a child's recovery and the influence of child's infirmity on the family. The importance of understanding the impact of culture on family health and nursing is related to a considerate practice of the family, as it establishes a realism that confirms the analysis that professional nursing perform which is crucial to health care. As realization increases on the influence of culture, concern is heightened in improving the efficiency of the involvement, given inconsistencies of cultural diversity, and the survival of children of minority families. (Radin, N., & Goldsmith, R. 1983 p 18) psychological needs for identity and sense of historical continuity. The ethnic background influences our way of thinking, our way of feelings, our way of working, and our way of relaxing, our way of celebrating holidays and customs, our way of expressing our anxieties, our way of belief about illness or life and death. Patterns of ethnicity, strengthened by family custom and community association, can function in delicate ways, normally outside of our consciousness; but their influence may however be extensive, deep and compelling. These patterns are capable to perform a significant responsibility throughout the family life series, though influence may differ among groups and within a group itself. In few families who cling to customary ways, adhering to groups from their spiritual or cultural background and apart from all others, ethnic values and classifications may be predominantly strong and probably to be kept for generations (Pleck 2000 p 48) Gender - a study shows that children at two and a half years of age practice gender classifications in negotiating their humanity and are possible to simplify gender classifications to several of activities, objects, and professions. Children yet refuse the truth of what they are perceiving when it does not correspond to their gender principles, such as the interpretation of a child that only men are doctors, when his or her mother is. Sons have a precise boundary concerning parental choices with regard to children; as majority of parents rather have male than female children, recognized all over the world. In the same manner, people who favor sons are more possible to apply technology for deciding on the sex of their child. This inclination for male children, furthermore, is accentuated by the ruling that parents are more possibly to maintain having children if they allow only girls than if they allow only boys. Explanations given by women for their choice for sons are to satisfy t heir husbands and to maintain the family name, and to be a companion to the husband. However, the reason for women desiring for daughters is their need for a companion for themselves and to have fun dressing a girl and doing her hair. 3 Parents influence their sons and daughters to get involve in sex-typed endeavors, as well as doll playing and managing housekeeping endeavors for girls and playing with trucks and participating in

Care given to a 15 day old baby with breathing difficulties Essay

Care given to a 15 day old baby with breathing difficulties - Essay Example Moreover, the paper will include efforts to understand the foetal circulation in relation to a neonate circulation along with an explanation of provision of the most appropriate treatment and care to Flora, as well as to her family members. Lastly, the researcher will endeavor to provide a clarification of ways that a children’s nurse can take to make a respiratory assessment of a child of Flora’s age, as well as assessments of older children. Discussion On arrival at The Royal Manchester Children’s Hospital, the team took Flora to the resuscitation room where they noticed her having breathing difficulties and a high pulse rate. Results of the initial assessment indicated her to be at a high risk; however, it was usual as infants often confront respiratory distress and similar signs and symptoms due to undiagnosed cardiac problems (Fergusson, 2008, 23-39). Subsequently, Professor Carley evaluated Flora’s physical condition and her behaviour using observati onal assessment of her airway, breathing, and circulation (Resuscitation Council UK, 2006, 1-10). It was noticeable that Flora was able to move all of her limbs with vigour, and there was no evidence of pallor that could indicate hypoxia (Fergusson, 2008, 35-40). In addition, the team noticed signs of efforts for breathing and visual signs of recession while observing Flora’s chest (Nursing and Midwifery Council, 2010, 29). The team also listened to the sound of Flora’s breathing, and luckily, both nasal flaring and chest recession were evident. Vital signs such as, temperature, blood pressure, pulse rate, respiration rate, and oxygen saturation were intact and functioning (Federspiel, 2010, 135). Furthermore, the team took blood samples for testing, which revealed that her kidneys were working in satisfactory condition and she was not anaemic, and additionally, Flora’s iron levels in her blood were normal as well. The hemoglobin levels in her blood were good, o xygenated cells were in high enough numbers within the blood to deliver oxygen to all tissues around the body that was another good sign. In addition, the team carried out blood tests to check PH imbalance and white cell count, as when in high numbers, they could indicate infection (Harrison, 2008, 56-67). After evaluating all these tests, Professor Carley reassured Flora’s parents by using the word ‘safe’ while explaining her immediate condition. In particular, Flora was at an age when cardiac abnormalities are often usual. One of the reasons is that in utero, the foetus obtains oxygenated blood, and nutrients from the placenta via the umbilical vein as defined by Chamley et al (2005, 11-26), and the lungs are not functional at this stage. At birth, important changes occurred to turn the foetal circulation into that of a neonatal circulation and before a baby can take in oxygen; her heart had to connect with the lungs (Holmes, 2010, 12), and this transition enab led Flora’s body to take over and begin to work independently (Glasper et al., 2007, 30-55). In particular, with every baby’s first breathe, the airways open and the drop-in pressure causes blood to rush to the lungs to receive oxygen, this oxygen reaches blood, and subsequently,

-Outline and explain the relations between senders and receivers of Essay

-Outline and explain the relations between senders and receivers of communication, focusing on how messages are - Essay Example Communication is said to be complete when immediate feedback of the message is received involving matters speech, body language, emotions and gestures. This process involves at least two persons and it starts when one individual intends to pass a message to another person. Communication starts with crafting of images and ideas in the mind of a person who wants to send the message. This can be a feeling, an idea or even a concept. This part of the communication process is in reflection (Guffey et al., 2013). In order to pass this message to another person, the individual intending to pass the message must be able to translate the crafted images into signs that the intended person of the message will be able to interpret and understand. Signs in communication can be words, sounds and sense, and this is the only way the images in the mind can be expressed in the form of meaningful ideas and passed on to another person. This process is referred to as encoding. Upon encoding the message, it is expected to be transmitted to the person intended, and that is the recipient (Lehman et al., 2011). Transmission of the message can be done in various ways, for example, orally, and this may include one-on-one verbal interaction and use of telephone. The message can also be transmitted through non-verbal means, and this can be done through short messages services, newspapers and letters. Another form of medium includes visual media; finally, the process in which the recipient translates the symbols or wording into such information that he or she can understand is called decoding. Diagrammatic representation of communication process Medium Medium From the diagram above, we can see the process involved in communication right from its initial stage until it reaches the intended audience, i.e. the receiver. The letter X represents encoder while the letter Y represents decoder. This model represents communication process from the person sending to the person receiving it (Barker, 2 010). The relation between Encoder-decoder At this time, the message is interpreted as having a nonfigurative reality which encoding shapes into an actual form that can be conveyed. Decoding has the capacity to reinstate it to its inventive nonfigurative meaning. The two terms, encoding and decoding, mean that text is made up of a number of codes resulting from another text (Wood, 2003).   To deliver a message effectively, the sender and the receiver need to take care of: Maintenance of eye contact to increase message flow and interest in the information; it shows utmost attention and increases the likelihood that feedback will be received in the communication process. It also gives the urge to continue with the communication interaction in a bid to pass information consequently with the right encoding and decoding. Facial expressions, for example, in smiling, while conversing would mean an acceptance of the message by the receiver and vice versa if the recipient has, for instance , a sad face. Gestures should be part and parcel of communication; for example, if the sender is throwing her or his hand with a message like â€Å"Go away!† this should indicate a situation in which the recipient is not needed in that particular place. Proximity, i.e. reasonable distance between the sender and the recipient as regards the channel used. Body language and/or posture, for example, leaning towards the sender, gives a connotation that the

A research paper on the representation of the goddess Isis in Ancient Term

A research on the representation of the goddess Isis in Ancient Egypt from Old Kingdom to New Kingdom - Term Paper Example The people sought the support and benevolence of various gods and goddesses for peace, prosperity, love, war, fertility, health, protection, traveling and other fields and activities of life. For instance, Zeus is viewed as the mighty king of all gods and goddesses of ancient Greece, while Apollo is believed to be the god of the sun and music and Mars is the god of war, while Eurybia is the sea goddess. The same is applied to the Egyptian civilization of ancient times, where the people had developed faith in supernatural powers, and sought their help at every hour of need. Hence, the innate human instinct also forced the financially affluent and politically powerful Egyptians of ancient times to call for the divine support on domestic, personal, professional and collective matters. Somehow, the Egyptians lacked hegemony and cohesion in views and beliefs; which was partly because of the social, geographical and strategic division of the population, which did not accept the subjugation under one political authority and one single deity as well. â€Å"Egyptian mythology is of highly complex character, and cannot be considered apart from its racial and historical aspects. The Egyptians were, as a Hebrew prophet has declared, a "mingled people", and this view has been confirmed by recent ethnological research.† Consequently, they had developed belief in the multiplicity of gods and goddesses on the basis of clans and tribes on the one hand, and in the light of the traditions accredited to different deities on the other. (Mackenzie, 2002:2) The goddess Isis is also one among the long list of deities, which were worshipped by the ancient people of Egyptian peninsula with great religious fervor and enthusiasm. Being an extremely benevolent and compassionate goddess, she enjoys distinguished status in the ancient Egyptian mythology. Though the goddess maintained a universal status in the country, yet she got popularity and position in the southern regions of Egyp t, which was not only the center of social, political and economic activities, but also dominated the rest of the region. â€Å"Currently there is a strong indication that Southern or Upper Egypt had gained a cultural ascendancy over Northern or Lower Egypt by c.3500 BC. In archaeological terms this southern culture is described as Naqada II.† (Hart, 2005:3) Hence, southern Egyptians declared their peace and prosperity as the outcome of the special bounties of the goddess upon them, which also motivated the northern areas of the country to imitate their footprints in spiritualism and faith. Isis is regarded as the goddess of motherhood, feminism, civil liberty, magic and fertility, and is revered and adored for displaying sheer affection and motherly attitude towards the Egyptian subjects without exhibiting any prejudice and discrimination towards any specific group or stratum of society. Oxford Encyclopedia of Ancient Egypt portrays Isis as the queen and mother of all the Eg yptians, which looked for bestowing maximum bounties and blessings upon the people to fill their life with countless joys in the form of abundance in food, children, pelf, possession and properties. â€Å"Isis had been a potent goddess as early as the third millennium B. C. She was the sister-wife of Osiris, with whom she mated in the womb of their mother, Nuit, the sky goddess.† (Mathews, 2001:25) Being the motherly deity, the goddess appears to be showering her unabated love on all and sundry, with special concentration of
