Blood pressure laboratory report

Blood pressure laboratory report Abstract The aims of the experiment were to measure blood pressure in a female volunteer using auscultation, cardiac microphone and an automated blood pressure meter. Moreover, monitoring changes in blood flow and blood pressure in the leg whilst sitting and standing. In some exercises this was carried out by using a pressure cuff and listening for Korotkoff sounds with a stethoscope or microphone. An automated blood pressure meter was also used as well as recording when the pulse reappeared in the finger/leg after the blood pressure cuff had been inflated, via the use of a pulse transducer. The main conclusions of the experiment were that the blood pressure measurement differed more for the cardiac microphone technique (mean of 96.31/77.01 mmHg) than auscultation (93/71.33 mmHg) and automated blood pressure meter (94.33/71.33 mmHg); however there was little variation between trials in all methods. In exercise 4 there was a delay from hearing the Korotkoff sounds, to observing a pulse after t he cuff was deflated. Lastly, there was a difference in blood pressure between the arm and leg whilst sitting (96.33 and 89.98 mmHg respectively) and between the leg whilst sitting and standing (89.98 and 114.44 mmHg respectively). Introduction The cardiac cycle involves increasing aortic blood pressure above the veins, causing blood flow through the systemic circulation. Blood flow (pulse) through the pulmonary circulation is caused by higher pressure in the pulmonary arteries than pulmonary veins [1]. Systolic blood pressure, the maximum blood pressure, arises when the heart contracts, pumping blood into the aorta (systole). Diastolic blood pressure, minimum blood pressure level, in which the ventricles relax causes arterial pressure to decrease resulting in the heart refilling with blood (diastole) [2]. The mean arterial pressure (MAP) can be calculated by taking into account the diastolic and systolic blood pressures. However, this value is not just the average of the two determinants [4]. Both these pressures can be determined by implanting a pressure catheter into an artery, and measuring pressure changes as the heart beats [5]. This process though accurate, can be both uncomfortable and invasive, and is rarely used. Hence, blood pressure is more commonly measured by way of auscultation, an indirect, non-invasive technique, whose setup can be seen in figure 1. Auscultation depends on silent streamlined flow but the production of Korotkoff sounds during turbulent flow, by listening through a stethoscope placed on the brachial artery, and recorded by a sphygmomanometer. This method involves placing an inflatable cuff around the patients upper arm, which is slowly inflated until the pulse cannot be felt (cuff pressure higher than systolic pressure). The pressure inside the cuff is steadily lowered until a tapping sound is heard (systolic blood pressure) where the artery pressure is now adequate to rise above that in the cuff. As cuff pressure is further reduced, the heart sounds become louder and then abruptly become weakened as diastolic pressure is approaching and flow is more streamlined. The point at which the heart sounds stop altogether is the diastolic blood pressure, in which normal flow has been resumed [1]. Normal blood pressure should be around 120/80 mmHg [6]. The main aims of the experiment are to compare the auscultation, cardiac microphone and automated blood pressure meter techniques for measuring blood pressure. In addition, compare blood pressure at different body locations i.e. arm and leg whilst sitting and standing. Results The mean blood pressure was 93/71.33 mmHg, showing diastolic and especially systolic values are below reference range. Over the three trails the MAP was 78.55 mmHg, which is within the normal range (~ 70-100 mmHg). The standard deviation for each parameter was very similar (2, 1.53 and 1.68), implying that the normal distribution is very narrow, with the majority of data concentrated around the mean. A mean blood pressure of 96.31/77.01 mmHg indicates that diastolic and systolic values are below normal reference range. Over the three trials, the MAP was 83.44 mmHg, which is within the normal range. The standard deviations for each parameter were similar (2.39, 1.15 and 1.53), implying the data had low dispersion. The reappearance of Korotkoff sounds while the pressure cuff was being deflated corresponds to the systolic blood pressure (96.21 mmHg). The diastolic blood pressure is marked when the sounds fade away (77.52 mmHg). The mean blood pressure was 94.33/71.33 mmHg, indicating that diastolic and systolic values are below normal range, whereas the MAP (79 mmHg) over all three trials, were in normal range. The standard deviations for each parameter were extremely similar (1.15, 1.15 and 0.67), implying little variation. The Korotkoff sounds and pulse signal fade away when the pressure cuff is inflated and then reappear while the cuff is being deflated. The pressure at which the Korotkoff sounds reappear is recorded as the systolic blood pressure (96.33 mmHg) which appears just before that of the pulse. The leg systolic pressure (114.44 mmHg) whilst standing, taken from when the pulse reappeared when the pressure cuff was being deflated, was higher than that whilst sitting (89.98 mmHg). Moreover, the pressure in the arm (96.33 mmHg) was higher than that of the leg whilst sitting but lower than that of the leg whilst standing. Discussion Using the stethoscope can lead to errors such as the pressure cuff being too big, leading to lower results than expected e.g. mean blood pressure of 93/71.33 mmHg in the auscultation technique. Moreover, incorrect positioning of the stethoscope or slow inflation of the pressure cuff can cause venous congestion resulting in faint Korotkoff sounds. Likewise, if the cuff is inflated immediately after the previous trial, it can cause venous distension, distorting the Korotkoff sounds. Excess pressure on the stethoscope bell can disturb arterial flow, muffling the sounds, especially in a noisy environment. In addition, one individuals perception of systolic, tapping sounds may be different to that of another [3]. Lastly, the volunteer may be suffering from white coat hypertension or feel uneasy as a result of the laboratory setting; however these tend to result increase blood pressure [6]. The experiment could have been improved by having different sized pressure cuffs, having separate ro oms when listening for Korotkoff sounds to reduce misinterpretation, and taking longer breaks in between the different trials to ensure normal blood flow has been resumed. The Korotkoff sounds reappear just before that of the pulse in exercise 4, because the sound of the blood spurting into the artery happens before the pulse manages to flow to the finger. An ausculatory gap can arise in between the systolic and diastolic pressures, in which the Korotkoff sounds fade away and then reappear at a lower pressure [1]. This can bring about some confusion to what is the true blood pressure; however this could not be seen in any of the exercises. The reappearance of blood flow to measure systolic pressure can be more accurate if the pressure cuff is released at a lower rate (e.g. 1 mmHg each time), as the true pressure may be missed if the pressure is released too quickly, and hence would lead to a lower result. In exercise 4, the diastolic pressure corresponds to the reappearance of the pulse. Hence, this method will be able to replace the auscultation and cardiac microphone techniques as it can measure both systolic (reappearance of Korotkoff sounds) and the diastolic pressure (reappearance of the pulse). There was a noticeable difference between pressure in the arm (96.33 mmHg) than in the leg (89.98 mmHg) whilst standing (6.35 mmHg). This difference will probably be due to experimental errors such as cuff size or misinterpretation of sounds. Less obvious explanations may be narrowing of the arteries or reduced blood flow in the leg. When the volunteer stood up, the blood pressure in the leg increased by 24.46 mmHg, because the pressure in the veins below the heart are increased, but are reduced in veins above the heart due to gravity. Hence, there is a reduced venous return, causing the leg pressure to increase. Furthermore, when comparing the three different techniques, the cardiac microphone had less similar results to the other two. For example, this method had a MAP of 83.44 mmHg compared to 78.55 and 79 mmHg for auscultation and automated blood pressure meter respectively. It seems that the cardiac microphone had greater values, especially diastolic pressures, having a mean of 77.01 mmHg. This could indicate incorrect positioning of the microphone, too much finger pressure on the microphone, difficultly listening for the sounds or inaccurate interpretation of the graph/sounds. There was little variation between the trials in all the methods, indicating that the results were accurate and reliable. As mentioned previously, the MAP is not simply the average of diastolic and systolic pressure because the arterial blood spends more time near to the diastolic pressure than the systolic pressure, and hence the equation takes this into account. The diastolic pressure has been shown to be less variable across the methods (low standard deviation) as it occurs in between heart beats, whereas systolic pressure can rapidly change in response to various triggers such as exercise.

Discuss the nature and quality of make-belief play Essay

Discuss the nature and quality of make-belief play, and the particular ways in which it relates to drama.  Drama in education requires an atmosphere of ‘playfulness’. We must be prepared to play with ideas, our bodies, voice, self and others. Young children do this naturally, learning by thrilling experience of living. Children ‘make’ their world in ways not dissimilar from theatrical form. Children’s play and theatre can be seen as constituting two ends of a continuum. These are theatre games and theatre. Drama in education inhabits the area in between. It can move towards the play end, where very young children are engaging in drama that is close to their own form of free play. The difference, however, is that it takes place as a result of teacher intervention, in that the teacher locates the drama activity in a particular aspect of living. Older students may work very close to the ‘theatre’ end of the continuum, where performance skills and communicative intention are paramount. At any one time, the teacher of drama needs to know at what point on the continuum she/he is working. For young children, dramatic play provides a journey into the world of â€Å"let’s pretend,† where they can readily transform themselves into the role of any character they choose. A story can be created as a script, often with a theme, where expressive actions convey a sequence of events that construct the plot. Whether the style of drama appears connected to occupations such as being a fire-fighter, a community happening such as a big snowstorm, or a fictional representation of The Three Bears, children are actors, producers, directors and set designers. By engaging in meaningful dialogue, their language and non-verbal gestures gradually reveal what they know and what they want to express. Dramatic play benefits children in all developmental areas. As children engage in fantasy play, they re-live experiences by symbolically imitating what they observe around them. Through children’s interpersonal relationships within socio-dramatic play, opportunities arise for in-depth thinking such as imagining, recalling, reasoning and negotiating (Vygotsky). By exploring life’s situations from the community and home, a child can re-create an identity that fulfils personal emotional needs and desires. The compelling urge to become physically powerful and socially dominant is fulfilled when a child adopts the role of a superheroine such as Princess Xena .While a traumatic family event can be played out as therapeutic drama when a child transfers inner feelings of rejection or hostility towards dolls or soft toys. The need for reassurance can be provided in dramatic play when a child knows it is acceptable to take on the role of being a baby, so that any sense of displacement, caused by the arrival of a new sibling within the family, is eased. Children have the freedom to be active and spontaneous in dramatic play, because, as Eden says, â€Å"it can be undertaken without regard for external goals and sanctions.†

This study examines the impact of liquidity on Islamic banks profitability during an 11 years period of 2001 to 2011. To explore and interpret the results the study has taken samples from five Islamic banks that have been in operation in Bangladesh on or before 2001 to till date. In order to construct the liquidity model it used four liquidity variables namely cash due from banks to total assets (CDTA), cash due from banks to total deposits (CDDEP), investment to total assets (INVSTA) and investment to total deposits (INVSDEP). Don’t waste time! Our writers will create an original "The Liquidity On Islamic Banks Finance Essay" essay for you Create order According to adjusted R squares profitability variables return on assets (ROA), return on equity (ROE) and return on deposits (ROD) are respectively 17.1%, 4.5% and 24.6% dependent on independent variables. The statistical results suggest that CDTA is found insignificant with all profitability variables, whereas CDDEP is individually significant with all profitability variables except ROE. On the other hand INVSTA and INVSDEP are recognized significant with all three profitability variables. However, when ROE stands for an insignificant relationship with the overall liquidity model, ROA and ROD are identified significantly correlated with the similar model at 1% significant level. The findings do strengthen the specification that the impact of liquidity reflects adequate imposition on profitability that the Islamic banks in Bangladesh must abide by. Keywords: Dependency level; Islamic Banking Goals; Liquidity ratios; Profitability ratios; Significance level. JEL Classification: G21 Introduction Business in Islam has always been viewed as an opportunity for potentials as long as it stands on moral and ethical grounds and conforms to the Islamic code of conduct. The actual role of Islamic bank inherits in promoting and empowering the banking services and product based on Islamic principles. The main principles of Islamic banking comprise of prohibition of interest in all forms of transactions, and undertaking business and trade activities on the basis of fair and legitimate profit (Haron and Shanmugan, 1997). But according to Islamic principles, reward, i.e. profit without sharing the risks or hazards in the economic understandings is totally prohibited. Perhaps, the most significant risk of an Islamic bank is to build a sound liquidity management. Islamic banking has gained much popularity in Bangladesh over the last few years. There is a high demand for interest-free banking services from a segment of people in Bangladesh who have a strong desire to abide by the rules and principles set by Shariah. Along with religious requirement, economic exigencies provide a new outlook to the role of banking in promoting investment / productive activities, influencing distribution of income and adding stability to the economy. The downturn in the United States in the late part of 2008 led to a dramatic downturn in businesses and financial institutions, not only in the United States but other countries as well (Lau, 2008). It affected the world stock markets and made large financial institutions to either go bankrupt or sell off their shares to the public (Anup, 2009). But surprisingly it could not affect the Islamic banking industry as much as expected. Most banks now keep protective reserves on top of planned reserves. Excess liquidity is reported in nearly all Islamic banks (Ali and Howlader, 2005). Due to unavailability of local capital market, Islamic banking sectors have been suffering from investing idle fund in liquid venture (Rashid and Nishat, 2009). Surplus liquidity with Islamic banks cannot be easily transferred to conventional banks since the Islamic banks do not accept interest; however there is room for exchange of surplus funds among the Islamic banks on a Mudarabah / Musharakah basis. The greater the number of Islamic banks and wider their activities, the greater will be the scope of cooperation in this field. So, what should be the crucial choice of an Islamic bank; whether to take fundamental choice of profit maximization or to concern more on assurance of liquidity in any banking business under Islamic principles? Possibly the answer could rise if we can have ideas on how liquidity position affects Islamic banks profitability. Analysis of financial statement has become very significant due to widespread interest of various parties in the financial result of a business unit. As a Muslim community, Bangladesh and its people are in greater interest for a Shariah approved banking system. The question from the pe ople arise when there are any lacking in response to customers demand (liquidity risk) as well as any deficiency in showing upward banks value (profitability risk). Consequently this is a demand of time now to evaluate the impact of liquidity risk on profitability for overall Islamic banking industry in Bangladesh, as this paper attempts to find. Literature Review Banks today are under great pressure to perform- to meet the objectives of their stockholders, employees, depositors and borrowing customers, while somehow keeping government regulators satisfied that the banks policies, loans and investments are sound (Rose, 2004-2005). At present a lot of countries around the world having twofold banking system, as interest free banks are functioning parallel to conventional banks (Akhtar, Ali and Sadaqat, 2011). In Islam, profit is simply a reward of taking risk. So, it should be a natural outcome of the fair play of the twin forces of demand and supply in the market (Latif, 1982). On the other hand liquidity implies availability of cash that how bank rapidly may convert its assets into cash to meet the need of short term. It is considered that it is life of the banks. Higher amount of the liquid assets reflect the greater liquidity of the firm (Akhter, Raza, Orangzab and Akram, 2011). The essence of liquidity management problem arises from t he fact that there is a trade-off between liquidity and profitability and mismatch between demand and supply (Khan and Ahmed, 2001). While the bank has no control over the sources of fund (deposits), it can control the use of funds. To support their depositors demand, banks need money, or in other sense the power to create money. That is why Akkas (1982) suggested that commercial banks should be compelled to keep reserves up to the full amount of their deposits, a reserve of 100 percent. Islamic principles are always in favor of non-inflationary economy. Therefore, bringing a kind of equilibrium between demand and supply for investible funds appears to be a major concern for financial intermediation (Siddiqui, 2010). But, it is to be noted that Islamic market mechanism does not support the concept of equilibrium price, rather, acts as the instrument to meet the effective demand of a consumer.  [1] Not only does Islamic banks profitability seem less volatile than that of convent ional peers, but it is also higher on average, at least in the GCC region (Hassoune, 2002). Haron (2004) said that liquidity, total expenditures, funds invested in Islamic securities, and the percentage of the profit-sharing ratio between the bank and the borrower of funds are highly correlated with the level of total income received by the Islamic banks. Similar effects are found for external factors such as interest rates, market share and size of the banks. He also added that other determinants such as funds deposited into current accounts, total capital and reserves, the percentage of profit sharing between bank and depositors, and money supply also play a major role in influencing the profitability of Islamic banks. Return on assets is a good indicator of a banks financial performance and managerial efficiency. It shows how competent the management is in allocating asset into net profit. The higher the ROA, the higher is the financial performance or profitability of the bank s (Samad, 2004). Return on equity measures the rate of return on the bases of capital and equity capital (Akhter, Raza, Orangzab and Akram, 2011). This ratio indicates how bank can generate profit with the money shareholders have invested. The higher value of this ratio shows higher financial performance. Like ROA, ROE is also an indicator for managerial efficiency (Ika and Abdullah, 2011). Return on deposits shows percentage return on each currency of customers deposit. In other words, it indicates the effectiveness of bank in converting deposit into net earnings (Rosly and Bakar, 2003). However, profitability is only part of bank performance story (Samad and Hasan, 1999). Cash in a bank vault is the most liquid asset of a bank. Cash assets include vault cash held on bank premises, deposits the bank holds at the Central bank in its district, deposits held with other banks to compensate them for clearing checks and other interbank services, and cash items in the process of collec tion (Rose, 2004-2005). A higher cash-deposit ratio indicates that a bank is relatively more liquid than a bank which has lower cash-deposit ratio. Depositors trust to bank is enhanced when a bank maintains a higher cash-deposit ratio. On the other hand an increase in loan-deposit ratio indicates that a bank is in more financial stress by making too much loan. Therefore, lower loan-deposit ratio is always favorable to higher loan-deposit ratio (Samad and Hasan, 1999). Loans-assets ratio measures the percentage of assets that are tied up in loans. The higher the ratio, the less liquid the bank will be (Samad, 2004). While making significant progress in return on assets (ROA) and return on equity (ROE), the liquidity performance of Bank Islam Malaysia (BIMB, the single full-fledged Islamic bank in Malaysia) between 1984-89 and 1990-97 in various measures such as cash-deposit ratio, loan-deposit ratio and current ratio showed neither deterioration nor improvement (Samad and Hassan, 1999). Chowdhury and Ahmed (2009) investigated that total deposits of Islami Bank Bangladesh Ltd. was higher in comparison to some non-Islamic banks during 2002 to 2006. Saifullah (2010) argued that Islamic banks in Bangladesh are superior to Conventional banks after an overall assessment of financial performance including liquidity and profitability position. When making comparisons across firms (or over time), it is useful to control for differences in their resource base (Foster, 2002). At the same time liquidity of those resources is of paramount significance for banks (Maheshwari and Maheshwari, 2002). Akhtar, Ali and Sadaqat (2011) found positive but insignificant relationship of size of the bank and net-working capital to net assets with liquidity risk in Islamic banks. In addition return on assets (ROE) in Islamic banks is found to be positive and significant with liquidity risk at 10% significant level. A study over determinants of Jordanian Islamic banks profitabilit y revealed that there are significant and positive relationship between Return on Assets and Provision for Credit Facilities + Interest in Suspense / Credit Facilities, Total Equity / Total Assets and Total Income / Total Asset of the Islamic banking, and there are significant and negative relationship between ROA and the Bank Size, Total Liabilities / Total Assets, Annual Growth Rate for Gross domestic product, Inflation Rate and Exchange Rate of the Islamic Banking. Also this study found that there are significant and positive relationship between Return on Equity and Log TA, TL / TA, TI /TA and ERS of the Islamic banking, and there are significant and negative relationship between ROE and PRFCFI / CF, TE / TA, GDPGR and INF of the Islamic Banking (Khrawish, Siam and Khrawish, 2011). Naceur and Goaied (2010) investigation regarding the determinants of the Tunisian banks performances during the period 1980-1995 showed that the principal determinants of a banks performance are by order of importance: labor productivity, bank portfolio composition, capital productivity and bank capitalization. Athanasoglou, Delis and Staikouras (2008) examined the profitability behavior of bank-specific, industry-related and macroeconomic determinants, using an unbalanced panel dataset of South Eastern European (SEE) credit institutions over the period 1998-2002. The estimation results indicated that, with the exception of liquidity, all bank-specific determinants significantly affect bank profitability in the anticipated way. The paper concludes with some remarks on the practicality and implements ability of the findings. Using bank level data for 80 countries in the 1988-1995 periods, a study suggested that interest margins differences and banks profitability reflect a variety of determinants such as; bank characteristics, macroeconomic conditions, explicit and implicit bank taxation, deposit insurance regulation, overall financial structure, and several underlying lega l and institutional indicators (Demirgà ¼Ãƒ §-Kunt and Huizinga, 1998). Shahchera (2012) analyzed the impact of liquid asset holdings on bank profitability for a sample of Iranian banks. Applying the Generalized Method of Moment (GMM), this study analyzed the profitability of listed banks using unbalanced panel data over the period of 2002-2009. An important finding of this study is that the business cycle significantly affects bank profits. The coefficient of regulation is negative and significant. Therefore if regulators reduce the constraints imposed on banks, banks obtain profit. Liquidity is of vital importance to the daily operations of a bank. Maintenance of a sound liquidity position of the bank is necessary to protect the bank against uncertainties of its business. Maintenance of liquidity bears both risk and return. A tradeoff between these two elements can minimize the conflict between liquidity versus profitability of a bank (Islam, 2008). As stated by Islam (2008) K och (1992) believed that there is a short-run tradeoff between liquidity and profitability. The more liquid a bank is, the lower are its return on equity (ROE) and return on assets (ROA), all other things being equal. Therefore, statistical significance of liquidity on profitability can be a great factor for potential investors. In a nutshell the influence of Islamic banks liquidity cannot be negligible when considering profit as their most vigorous concern. Methodology 3.1 Sample Design and Data Collection In Bangladesh, currently seven Islamic banks are providing their services as pure Islamic banks and running their operations under the guidance of Islamic Shariah. Among them, five Islamic banks have been selected to investigate the impact of Islamic banks liquidity risk on profitability over the period of 11 years during 2001 to 2011.  [2]  Selected Islamic banks are- 1. Islami Bank Bangladesh Limited 2. Shahjalal Islami Bank Limited 3. Al-Arafah Islami Bank Limited 4. Export Import Bank of Bangladesh Limited 5. Social Islami Bank Limited The data used in this study are compiled from income statements and balance sheets of selected banks from their each year annual report. The study model is tested on time series cross-sectional bank level data in the context of Bangladesh over the period 2001 to 2011. Thus, present study has been conducted taking into account a total samples of [5ÃÆ'Æ’-11] 55 under each variable. 3.2 Explanatory Variables To analyze the liquidity impact on profitability using multiple regression analysis, variables were assigned into two sections- Dependent Variables: Return on Assets = Net Income after Taxes / Total Assets Return on Equity = Net Income after Taxes / Total Equity Capital Account Return on Deposits = Net Income after Taxes / Total Deposits Independent Variables: Cash Due from Banks to Total Assets = Cash Due from Banks / Total Assets Cash Due from Banks to Total Deposits = Cash Due from Banks / Total Deposits Investment (Loans Advances) to Total Assets = Investment / Total Assets Investment (Loans Advances) to Total Deposits = Investment / Total Deposits 3.3 Research Model and Hypotheses The current research is being conducted to evaluate the impact of liquidity on profitability by applying multiple linear regression model which had previously been developed and applied by Demirgà ¼Ãƒ §-Kunt and Huizinga (1999), Haron (2004), Athanasoglou, Delis and Staikouras (2008), Toni (2008), Naceur and Goaied (2008), Saleem and Rehman (2011), Khrawish, Siam and Khrawish (2011), Shahchera (2012) and many more in essence of their contribution to banking, economics and finance. Utilizing the similar model these preceding studies focused on assessing diverse determinants of Islamic banks profitability. Present study used the same model but for only to strengthening on liquidity variables in order to demonstrate their impact on profitability. Current research model is as follows- Where, ROA = Return on assets ROE = Return on equity ROD = Return on deposits CDTA = Cash due from banks to total assets CDDEP = Cash due from banks to total deposits INVSTA = Inve stment (loans advances) to total assets INVSDEP = Investment (loans advances) to total deposits ÃÆ'†°Ãƒ ¢Ã¢â€š ¬Ã‹Å" = constant term ÃÆ' ¡Ãƒâ€šÃ‚ µÃƒâ€šÃ‚ ¦ = slopes associated with the independent (liquidity) variables i = banks t = time ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒâ€šÃ‚ ¬ = error term To do the analysis following two hypotheses were designed: There is an insignificant relationship between liquidity and profitability, i.e. H0: b1 = b2 = b3 = b4 = 0 (null hypothesis) There is a significant relationship between liquidity and profitability, i.e. Ha: b1 ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã‚ °Ãƒâ€šÃ‚   b2 ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã‚ °Ãƒâ€šÃ‚   b3 ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã‚ °Ãƒâ€šÃ‚   b4 ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã‚ °Ãƒâ€šÃ‚   0 (alternative hypothesis) 4 Statistical Results and Analyses The statistical analysis of secondary data has been divided into three dimensions, i.e. descriptive, correlation and regression. All the statistical tests have been performed through SPSS V15.0. 4.1 Descriptive Statistics Table 1 shows descriptive statistics for dependent and independent variables. The analyzed statistics figures illustrate the mean, standard deviation, maximum and minimum values of Islamic banks. The statistics suggest irregular drawbacks in minimum value of ROA ROD, even more in ROE, leading to a dramatic decrease in percentage return for overall Islamic banking industry.  [3]  The mean value of dependent variables imply that maximum portion of banks income goes for shareholders, as here ROE indicates greater outcome in percentage return in comparisons to ROA or ROD. However, according to the statistics, the fraction of investment in total assets and total deposits exceeds cash due from banks to a great extent if we take a look at their mean values.

This gives information on the degree of correlation between all the dependent (profitability) and independent (liquidity) variables used in the analysis. The opportunity has been tested with the Pearson correlation coefficients test. The result indicates that the liquidity variables CDTA and CDDEP are negatively related with all selected profitability variables. On the other hand, the remaining two liquidity variables INVSTA and INVSDEP are positively related with all three profitability variables.

The adjusted value of R squares indicate that ROA, ROE and ROD of Islamic banks of Bangladesh are respectively 17.1%, 4.5% and 24.6% dependent on independent variables, i.e. CDTA, CDDEP, INVSTA and INVSDEP. Therefore, as liquidity factor, these four variables are considered major issues to defining profitability of Islamic banks in Bangladesh over eleven years period.

Alternatively CDDEP and INVSTA show negative relationship with ROA. With an exception to CDTA; rest independent variables CDDEP, INVSTA and INVSDEP are significantly correlated with ROA at 10%, 5% and 1% significant level in that order. Durbin-Watson test shows that the residuals are positively correlated. At overall 1% significant level as per p-value the liquidity model [Model 1] is significantly correlated with ROA. So the null hypothesis (H0) is rejected and alternative hypothesis (Ha) accepted here.

At the same time CDDEP and INVSTA create negative correlation with ROE. Here, only INVSTA and INVSDEP are found significant with ROE at 5% significant level. As Durbin-Watson statistic is approximately very close to 2, therefore the residuals are uncorrelated. However, according to p-value the overall liquidity model [Model 2] is not significantly related with ROE at any formulated level. Thus the null hypothesis (H0) is accepted for the relationship of liquidity and profitability (ROE).

Here, only insignificant variable is CDTA. CDDEP is significantly related with ROD at 10% level. At 1% significant level both liquidity variables INVSTA and INVSDEP are detected statistically significant with ROD. Durbin-Watson test indicates positive autocorrelation for the residuals. As per p-value the model [Model 3] is statistically significant with ROD at 1% significant level. As a result here the null hypothesis (H0) is rejected and alternative hypothesis (Ha) accepted. 5 Conclusion The current study marks the very first attempt to analyze liquidity impact on Islamic banks profitability in Bangladesh during the period 2001 to 2011. Major parts of the study results reveal greater dependency of banks profitability on liquidity. Specifically cash due from banks to total assets is not significant with any profitability variables. Cash due from banks to total deposits is found insignificant with ROE, but significant with ROA and ROD at 10% significant level. Other two independent variables investment to total assets and investment to total deposits are individually and significantly correlated with all selected profitability variables. Investment to total assets is significant with ROA and ROE at 5% significant level and with ROD at 1% significant level. On the other hand, investment to total deposits is significantly correlated with ROA and ROD at 1% significant level and with ROE at 5% significant level. The entire liquidity model is found statistically signifi cant with ROA and ROD at 1% significant level. The reason to discover ROE less dependent and insignificant with the overall liquidity model is possibly due to that huge loss in foreign transaction by Shahjalal Islami Bank Limited in the financial year 2004. However, adding further liquidity variable to the model may make it more or less significant with profitability. In addition, it should also be said that liquidity is not the single reason to defining Islamic banks profitability. Therefore, in any affair, current study serves as initial movement, leaving spaces for future researches to enhance and enrich its outlook.

Should Physician-Assisted Suicide Be Legal in Every State - Free Essay Example

Physician-Assisted Suicide, or PAS, consists of a terminally ill patient requesting to end their life on their own terms rather than letting the diagnosis determine their time of death. Patients are requesting to die with dignity instead of living their last moments in agony. Some can say that Physician-Assisted Suicide should not be an option. Don’t waste time! Our writers will create an original "Should Physician-Assisted Suicide Be Legal in Every State?" essay for you Create order One can argue that human dignity and life are sacred or that doctors have a specific role in keeping their patients alive, but should anyone have a say so in how you choose to live or die? With the rising costs of healthcare, suffering through a painful diagnosis, and laws that protect the patient and the person administering the lethal medication; Physician-Assisted Suicide should be legal in all 50 states. People are diagnosed with terminal illnesses every single day. One of the first conversations a Physician will have with a patient is palliative care options which begin at the time of diagnosis. This offers the patient a care option when there are no known cures for their illness. In severe cases, the Physician might directly request that the patient is put in hospice. While palliative care offers hope for a cure, hospice may be suggested if the patient has a terminal illness which would lead to death in a shorter amount of time with only a treatment plan specialized for maintaining a patientrs comfort. Both options are extremely expensive since most insurance companies do not cover all services rendered under palliative or hospice care. Many insurance plans cover some palliative care services, such as pain management. But they tend not to cover services delivered by registered nurses, social workers and chaplains. Many Medicare, Medicaid and private insurance plans offer scant or no coverage of home visits, coordination of care, wound care, social and spiritual counseling, 24-hour hotlines, advanced care planning and family support(para 14). While palliative care reduces the number of hospitalizations and frequent trips to the emergency room, the average cost for receiving this service is $95.30 per day (Ollove). If a patient is put directly on hospice, Medicaid will pay all expenses while Medicare pays for most services. Those on Medicare are still responsible for paying room and board if they are in a nursing facility, emergency care, and any medication attempting to cure their i llness (Fay). All these additional costs to pursue care quickly add up. If the alternate option of PAS was legal, that number would drop drastically. The most well-known medication for induced death is known as Seconal. When prescribed under the Death with Dignity law, this medication can cost upwards of $5,000. Due to an increase in price, alternate mixtures have been developed in order to cut costs. The phenobarbital/chloral hydrate/morphine sulfate mix has been found to produce a similar effect and has lowered the cost of PAS from $5,000 to $500 (FAQS). Physician-Assisted Suicide would not only help lift financial burdens placed on the patients and their families, but it would also help prevent them from suffering. Being diagnosed with a terminal illness is the first step on a long journey of pain, discomfort, and suffering. Depending on what diagnosis a patient receives will determine the amount of strain that will be placed on their body before they expire. Cancer is one of the leading causes of patients requesting Physician-Assisted Suicide. The effects of cancer itself are detrimental to oners health and the treatment options that are provided inflict more suffering. The side effects of treatment can include pain, nausea, swelling, memory loss, and becoming more susceptible to infections (Side Effects of Cancer Treatment). Along with cancer, AIDS also takes a toll on oners body. Once one is infected, they can expect to experience thrush, shingles, weight loss, and sores. As their infection grows, so does their unpleasant symptoms. The later stage of AIDS induces bacterial infections, fever, diarrhea, peripheral neuropathy, tuberculosis, and pneumonia (Mtwisha). There are several terminal illnesses that take a toll on everyone who is diagnosed. Patients should not be expected to live out their days in agony and their families should not have to watch them suffer. Legalizing PAS would put an end to their suffering and let the patients end their life on their own terms when they are ready. Choosing PAS is a viable option that is now legalized in California, Colorado, Hawaii, Oregon, Vermont, Washington, and DC along with Montana by Supreme Court ruling (State-by-State Guide to Physician-Assisted Suicide). Although Physician-Assisted Suicide is legal, there are specific eligibility restrictions that the states must follow. The patient must be a resident of the states listed above, they must be 18 years or older, and must be mentally competent. Patients must also be diagnosed with a terminal illness that will lead to their passing within a six-month period. Patients must also be able to take their prescribed medication without assistance. There are no exceptions to any of these rules. To obtain the dosages of medication, the patient must first make an initial oral request for the lethal medication. The physician who receives the request must be licensed in the patientrs state and the request must take place in that state. Secondly, the physician must confirm that the pat ient meets all criteria and they are also responsible for discussing all alternative care options. A second physician must confirm the illness, life expectancy, and mental competence of the patient. If one physician finds that the patientrs judgement is flawed, a psychological evaluation will need to be done before the patient can move forward with the PAS process. After both physicians find that the patient meets all criteria, the patient must wait a minimum of 15 days to make the second oral request. Once the second request is made, the prescription is written. At any given time, the patient can change their mind. They can choose to not fill the prescription or if the prescription is already filled, they can choose not to take it.(How Death with Dignity Laws Work). These restrictions help protect the patient who chooses PSA and Physicians that administer the medication. Most believe that a doctorrs main objective in their career is to keep their patient alive. In specific cases, they are right. When doctors know that the patient can make a recovery with little to no consequences of the diagnosis, they are expected to do whatever it takes to make sure that they do not have to call time of death. Doctors also must keep the patientrs best interest in mind. There should be an option for patients that have no cure available to them to pass before the diagnosis takes over them and they are no longer that person that everyone else had known. Human dignity and life itself are considered sacred. Keeping someone alive is not the only way of showing dignity. What life does someone have when he or she is no longer able to enjoy it? The pain from terminal illnesses alone is enough for a patient to lead a miserable life. Human dignity and the sacredness of life is the quality of life, not the quantity. Dignity comes when someone is suffering, and people offer the ir support with all choices made by that patient and standing with them in their time of need. Physician-Assisted Suicide should be legal in all 50 states. Patients should not have to suffer until their diagnoses take their life. Patients deserve to die with dignity without spending the rest of their lives in pain and the financial burden that continuous healthcare places on them. Laws have been placed to protect not only the physicians but the patients as well. Patients should have their voices heard when it comes to their own lives especially when dealing with something as serious as life and death.
