Three Activities (80 marks):
Please consider the following application scenario using Australian My Health Record (MHR) system.
A simple MHR scenario:
MHR is an initiative by Australian government that provides a secure online summary of the health information to the individuals. It can control what goes into it and who is allowed to access it. It can choose to share patients’ health information with their doctors, hospitals and other healthcare providers like pharmacists. In addition to such “primary use” of the data/information for the health services, there are plans to use aggregated and anonymised health data/information for research and other purposes – this is known as “secondary use”. Overall, the MHR system controls our health information securely in one place. It is really our choice – we can keep our MHR with basic information, or we can allow more information to MHR users or permanently delete the record. A MHR user is an individual who has right to use patients’ health information. For example, A Doctor can do the following actions in the MHR system: Login to the system, Access patients’ health information, Write prescription, Recommend patient to the specialists. The MHR system also gives our pharmacists a clearer picture of our health information.
More information about MHR can be found here: https://www.myhealthrecord.gov.au/. You can use other MHR scenarios/examples from other sources, however, please document your scenarios/examples and provide references.
Please follow the word limits that are mentioned in each activities.

A Critical Appraisal of the Literature on Diversification inside Private Real Estate Portfolios in the United Kingdom Dynamic One of the two noteworthy manners by which institutional speculators can put resources into land is "private land". Private land is to buy un-securitized land straightforwardly through property pools, mixed together land reserves (CREFs), syndications or separate records that are overseen by expert land portfolio directors or venture guides. This type of possession will from now on be alluded to as "private land". There are distinctive drivers of contributing inside the private land portfolios, including markets, areas, the executives, territory/building explicit, scale, broadening, liquidity, duty and administration dangers. The private land has a low dimension of straight reliance on value, so private land requires the enhancement of its portfolios. This paper gives a basic examination of the writing on broadening inside private land portfolios. Completes a U.K. showcase need to do the expansion inside private land portfolios when British individuals need it? Not by any means. Writing Review Interest in private land offers significant focal points: it is an unmistakable resource with low instability; and it creates an alluring salary stream and long haul capital gratefulness and especially solid expansion advantages to stocks and securities. Hence, there is surviving writing appearing private land has a critical spot in the U.S. blended resource portfolio: see Ziobrowski and Ziobrowski (1997); and Firstenberg, Ross and Zisler (1998); among others. Specialists led a few investigations on land's job as a part of advantage just portfolios, explicitly concentrating on land's expansion benefits. These examinations make up for a portion of the issues with land information, specifically, that of valuation smoothing. The vast majority of these examinations presume that the distribution to land ought to be from 10% upward. The outcomes show that constrained expansion advantages can be picked up from global interests in unadulterated office methodologies, especially for multi-resource speculators looking to decrease chance originating from the capital markets. Existing exact proof is commonly reliable with firm proprietors' portfolio broadening positively affecting their organizations' hazard taking (e.g., Amihud and Lev (1981) and Faccio, Marchica and Mura (2011)). The general subject in the current writing is that firm danger can be decreased fundamentally by methods for picking more secure speculations, for example speculations that outcome in lower income unpredictability or stock return instability (e.g., Lyandres, Marchica, Michaely, and Mura (2015) and Faccio, Marchica and Mura (2011)), or lower connection with the remainder of the firm leaders' money streams (e.g., Amihud and Lev (1981) and Gormley, Matsa and Milbourn (2013)). The relationship between private (compelled) firm proprietors' portfolio enhancement and speculation is negative and critical as a rule (Lyandres, Marchica, Michaely, and Mura, 2015). Lyandres, Marchica, Michaely, and Mura (2015) consider conceivable endogeneity of firm proprietor's portfolio broadening and of company's private status does not appear to drive their outcomes. The consideration of proprietor fixed impacts does not affect the subjective connection between proprietors' portfolio broadening and private firms' capital speculation (Lyandres, Marchica, Michaely, and Mura, 2015). Be that as it may, the fixed-impacts results may even now be influenced without anyone else's input choice: better-enhanced proprietors may choose to put resources into organizations with higher speculation rates, which better their hazard inclinations. Lyandres, Marchica, Michaely, and Mura (2015) recommend the organizations' capital venture relies upon portfolio broadening of their controlling proprietors; the impact of proprietors' portfolio enhancement on firms' speculation levels depends critically on firms monetary imperatives: the speculation expansion connection is sure for moderately unconstrained firms and is contrarily for generally compelled ones. Proprietor fixed-impacts, a semi characteristic investigation, and instrumental variable examination recommend that this outcome isn't driven by potential endogeneity of proprietor's expansion. Paper assistance from qualified, master scholars UK-Based • Trusted • Reliable • Secure FREE catalog and references with each request FREE copyright infringement output and report with each request £5,000 no-copyright infringement ensure Experienced and qualified journalists The Times Logo "The paper was freely surveyed by a main University as being of a 2:1 standard" A coordinated example examination, choice model, and an elective proportion of money related imperatives demonstrate that Lyandres, Marchica, Michaely, and Mura (2015's) discoveries are likewise not driven by the endogeneity of their intermediary for budgetary requirements. The investigation expands on and broadens that of Hoesli et al. (2004) however expands the length of the time arrangement and the profundity of examination as they relate to the land portfolio. They presumed that both local and worldwide land contribute with hazard expansion, and subsequently portfolio proficiency, to the multi-resource portfolio and that the information bolster an assignment to land of somewhere in the range of 15 and 25%, contingent upon hazard inclinations and the speculator's nation of residence. The intention is to examine how the sythesis of a land portfolio influences the capacity to accomplish hazard enhancement when the executives costs are considered and in the wake of expelling the suspicion that financial specialists can just by a land showcase portfolio. The examination adds to the group of learning by investigating how the sort of fundamental inhabitant request type influences the portfolio creation issue for land financial specialists and in this manner how land procedures ought to be formed to all the more viably bolster generally speaking portfolio targets. Hoesli and Lizieri (2007) report connections near zero for private land in the UK. Lizieri (2013) finds that the connection of the private land shifts essentially over the market cycle, tending to increment in periods from 1995 to 2010 of poor securities exchange execution. Lizieri (2013) finds that the connections of private land with values and bonds changed over the most recent five years of the example from around zero to 0.4 and - 0.5 individually. This would show that the broadening profits by land vanish when they are generally required. In any case, it is likewise discovered that when the fluctuation is decayed, a high extent of private land difference can't be clarified by more extensive capital market factors, which demonstrates considerable broadening benefits. Despite the fact that information development issues for private land can't be precluded, Lizieri (2013) reasons that the outcomes bolster the enhancement job of the private land. Ang (2012) investigates the qualities of land with regards to its genuine resource attributes alongside land's job in the benefit allotment confound. Ang (2012) presumes that land is not quite the same as other resource classes in a few regards: the peculiar hazard, the heterogeneity of the benefits and prerequisite to effectively mange land property. Ang (2012) additionally brings up the trouble of incorporating land in any advantage allotment demonstrate comparable to stocks and securities on the grounds that immediate land absolute returns are not returns in a similar sense as are complete returns for the other resource classes. This is on the grounds that land all out returns are not exchange based nor is there an approach to quantify the entire market. Ang (2012) does not say that land has no task to carry out yet rather that the main return got from land estimated on a similar recurrence as the arrival on develop resource classes is the pay return.

Private land lessens the danger of a portfolio since it has not exactly an ideal connection with stocks, bonds and every single other resource. Subjective Analysis Standard Markowitz portfolio determination demonstrate expect together typical and symmetric circulations. In the event that that holds, at that point mean, fluctuation and covariance are adequate to characterize viable broadening system. Customary broadening methodologies never again give wanted dimension of security in bear markets. Portfolio hazard and expected esteem fall in bear markets are methodicallly downplayed. Conventional thoughts of hazard return exchange off are deliberately exaggerated. Visit portfolio rebalancing expected to keep up target dimension of hazard, prompting higher exchange costs. For instance, Stichting Pensioenfonds X: Asset Mix is an original private land portfolio. 9% property designation is sensible for a very much subsidized and developing plan if expect fails to meet expectations values and out-performs bonds and includes some broadening. Higher portfolio enhancement lessens the difference of proprietor's portfolio return and its covariance with the association's income. Accordingly, higher portfolio broadening of firm proprietor lower>GET ANSWER
