Changing patterns in marriage Essay Example for Free

Changing patterns in marriage Essay Using information from the items and elsewhere, examine the reasons for changing patterns of marriage, cohabitation and childbearing in the last 40 years (24 marks) According to the Office for National Statistics, the highest number of couples in 1972 was 480,000 and was due to the baby boom generation of the 1950’s reaching marriageable age and the fact that people chose to marry at a younger age compared to pervious generations. However the annual number of marriages in England and Wales then went into decline and reached an all-time low in 2005 when only 244,710 couples got married. This decline in the total number of marriages has been paralleled by a decline in marriage rates. In 1994, the marriage rate was 11.4 but has decline to 10.3 by 2004. The male rate declined from 36.3 in 1994 to 27.8 in 2004 whilst the female rate declined from 30.6 to 24.6. Fears about what marriage statistics reveal are exaggerated for four reasons: People are delaying marriage rather than rejecting it. Most people will marry at some point in their lives, but people are now marrying later in life, probably after a period of cohabitation. Women may delay marriage because they want to develop their careers and enjoy a period of independence. The BSAS indicates that most people, whether single, divorced or cohabiting, still see marriage as a desirable life-goal. People also generally believe that having children is best done in the context of marriage and few people believe that the freedom associate with living alone is better than being married to someone. Two fifths of all marriages are remarriages. Evidently these people are committed to the institution of marriage despite their previous negative experience of it. Despite the decrease in the overall number of people marrying, married couples are still the main types of partnership for men and women in the UK. Wilkinson notes that female attitudes towards marriage and family life have undergone a radical change or ‘genderquake’. She argues that young females no longer prioritize marriage and children. Educational opportunities and the feminization of the economy have resulted in young women weighing up the costs of marriage and having children against the benefits of a career and economic independence. Therefore the result of this is that many females, particularly middle-class, are postponing marriage and family life until their careers are established. Other feminist sociologists are sceptical about the value of marriage. Smith argues that marriage creates unrealistic expectation  about monogamy and faithfulness in a world characterized by sexual freedom. She argues that at different points in people’s life cycles, people need different things that often can only be gained from a new partner. Campbell, however, suggests that marriage benefits men more than it does women. A constant source of concern to the New Right has been the significant rise in the number of couples cohabiting. The proportion of non-married people cohabiting has risen sharply in the last 20 years from 11% of men and 13% of women in 1986 to 24% and 25% respectively. In 2007, the ONS suggested that cohabiting couples are the fastest growing family type in the UK. Around 2.2 million families are cohabiting couples with or without children. This family type has grown by 65% since 1997. However, New Right commentators claim that cohabitation is less stable than marriage. A report by the Institute for the Study of Civil Society claimed that cohabiting couples were less happy and less fulfilled than married couples, and more likely to be abusive, unfaithful, stressed and depressed. Although surveys indicate that few people see cohabitation as an alternative to marriage, the fact that cohabiting couples are much younger than married couples suggests cohabitation is seen my many participants as a test of compatibility and an introduction to marriage. Other research suggests that cohabitation is a temporary phase lasting on average for about 5 years. Approximately 60% of cohabiting couples eventually marry. Although cohabitation marks a dramatic change in adult living arrangements – as recently as the 1960’s, it was regarded immoral – cohabiting couples with and without children only accounted for 10% of households in 2006. Reasons for increase in divorce rates: Thornes and Collard: women value friendship and emotional gratification more than men do. If the husband fails to live up to these expectations, women may feel the need to look elsewhere. Hart: divorce may be reaction to the frustration that many working wives may feel if they are responsible for the bulk of housework and childcare. Beck and Beck-Gernsheim (1995): rising divorce rates are the product of a rapidly changing world in which traditional rules, rituals and traditions of love, romance and relationships no longer apply. In 1938, 6,000 divorces were granted in the UK. This figure had increased tenfold by 1970, and in 1993, numbers packed at 180,000. By  2000, this figure had fallen to 154,600 although the years 2001-2004 have seen a gradual rise to 167,100. Flouri and Buchanan’s (2002) study of 17,000 children from families that had experienced separation and divorce found that in families, their fathers were still involved in their children so the children were more successful in gaining educational qualifications and continued to seek out educational opportunities in adult life. In conclusion, the reasons for changing patterns of marriage, cohabitation and childbearing in the last 40 years are due to the fact that conjugal roles within marriages have differed and the ability to change marriage beliefs in an instant. Men and women, especially the middle-class, may fear the need to put their careers before starting a family, which therefore causes problems within marriage.

Poetic Inspiration in Kubla Khan and Rime of the Ancient Mariner Essay

Poetic Inspiration in Kubla Khan and Rime of the Ancient Mariner      Ã‚  Ã‚   An examination of the characters that Coleridge presents in "The Rime of the Ancient Mariner" and "Kubla Khan" and the situations in which they find themselves reveals interesting aspects of Coleridge's own character that are both similar to and different from the characters named in the titles of these poems. In particular, an examination of these characters with an eye toward Coleridge's conception of poetic inspiration and success can be fruitful.    In "Kubla Khan," Coleridge depicts a powerful character who "did ... a stately pleasure dome decree" ("Kubla Khan" lines 1-2). The fact that Kubla Khan is able merely to decree a pleasure-dome and know that his orders will be executed implies that he is a character of both strong will and great creative power. This faith in himself is not misplaced. The Khan decrees that a pleasure-dome be built and his order is immediately executed: "So twice five miles of fertile ground/ With walls and towers were girdled round" (6-7). Some aspects of the landscape and the dome echo the hardness implied by the chieftain's single-minded determination: the fountain "with ceaseless turmoil seething," the "dancing rocks" that are tossed into the air by the fountain, the "ancestral voices prophesying war," and the fact that the sacred river itself is "flung up momently" by the fountain (18, 23, 30, 24). As the Khan's creation, the dome can reasonably be expected to contain clues to his character, and th e characterization of the Khan harmonizes well with these clues about his character given by the pleasure dome: the image of a Mongol chief is one associated with danger, war, and a large amount of strength.    ... ... of a broken and essentially conciliatory force. When seen in these terms, it seems that the mariner may be the image with which Coleridge most closely identified himself, but both are symbols of his creative process.    References The Bible.

A group II metal hydroxide Essay

To find the identity of X(OH)2 (a group II metal hydroxide) by determining it’s solubility from a titration with 0.05 mol dm-3 HCL Theory:1. Titrations are the reaction between an acid solution with an alkali. In this reaction (called neutralization), the acid donates a proton (H+) to the alkali (base). When the two solutions are combined, the products made are salt and water. For example: 2HCl(aq) + X(OH)2 (aq) XCl2 (aq) + 2H2O (l) This shows the one of the products i.e. salt being XCl2 and water. So titration therefore helps to find the concentration for a solution of unknown concentration. This involves the controlled addition of a standard solution of known. Indicators are used to determine, at what stage has the solution reached the ‘equivalence point'(inflextion point). This means at which, does the number of moles base added equals the number of moles of acid present. i.e. pH 7 Titration of a strong Acid with a Strong Base: As shown in the graph, the pH goes up slowly from the start of the tiration to near the equivalence point. i.e (the beginning of the graph). At the equivalence point moles of acid equal mole of base, and the solution contains only water and salt from the cation of the base and the anion of the acid. i.e. the vertical part of the curve in the graph. At that point, a tiny amount of alkali casuses a sudden, big change in pH. i.e. neutralised. Also shown in the graph are methyl orange and phenolpthalein. These two are both indicators that are often used for acid-base titrations. They each change colour at different pH ranges. For a strong acid to strong alkali titration, either one of those indicators can be used. However for a strong acid/weak alkali only methyl orange will be used due to pH changing rapidly across the range for methyl orange. That is from low to high pH i.e. red to yellow respectively pH (3.3 to 4.4), but not for phenolpthalein. Weak acid/strong alkali, phenolpthalein is used, the pH changes rapidly in an alkali range. From high to low pH, that is from pink to colourless pH(10-8.3) respectively but not for methyl orange. However for a weak acid/ weak alkali titrations there’s no sharp pH change, so neither can work. Therefore in this investigation, the titration will be between a 0.05 mol dm-3 of HCl with X(OH)2, using phenolphthalein. Dependant Variable: Is the volume of HCl to achieve a colour change that is from pink to colourless. The Controlled variables : 1. the same source of HCl 2. same concentration of HCl 3. Same source of X(OH)2 4. Same volume of X(OH)2 5. Same equipment, method, room temperature Controlled Variables How to control How to monitor 1. Same source of HCl Using the same batch of HCl or from the same brand will control this. If the concentration was not to be same throughout, then this will cause different ratios of the components of the solution, that might cause different volume of HCl to be obtained for the neutralization to occur. 2. Same concentration of HCl This will be controlled by using the same batch of HCl and from the same source i.e. the same brand. By using the same batch ensures that the reactant concentration is the same. If another batch were to be used causes the concentration to differ. This causes the HCl obtained to be different. 3.Same source of X(OH)2 Using the same batch of X(OH)2 or from the same brand will control this. If the concentration was not to be same throughout, then this will cause different ratios of the components of the solution that might cause different volume of HCl to be obtained for the neutralization to occur. 4. Same volume of X(OH)2 This will be controlled by using the same batch of X(OH)2 and from the same source i.e. the same brand. By using the same batch ensures that the reactant concentration is the same. If another batch were to be used causes the concentration to differ. This causes the HCl obtained to be different. 5. Same equipment, method, room temperature The method would be kept the same and the same set of equipment and brand will need to be used throughout. The room temperature will be kept throughout at 180C by using a water bath. If different equipment or brands were used then there would be a lot of anomalies in the experiment causing a huge amount of inaccuracy of measurement particularly. Results: Raw data results were collected by using 25.00 cm3 of X(OH)2 with phenolphthalein and the volume of HCl was obtained by the solution going from pink to colourless. The volume of HCl found in 50.0cm3 burette à ¯Ã‚ ¿Ã‚ ½ 0.05 cm3 Trial 1 Trial 2 Trial 3 Trial 4 Average 19.600 19.800 19.600 19.700 19.675 Qualitative results that occurred during the experiment: * Conical flask swirling not even between the trials * Difficult to judge ‘colourless’ solution change – subjective end point * Ability to measure 25cm3 * Filling of burette accurately with HCl – 0 point in right spot * Residual distilled water or solutions remain in conical flask i.e. diluted/interfered with subsequent solutions of X(OH)2 Average = trials (1+2+3+4)/4 Therefore: (19.6 + 19.8 + 19.6 + 19.7)/4 = 98.5/4 = 19.675 Due to the equation being 2HCl(aq) + X(OH)2 (aq) XCl2 (aq) + 2H2O (l) Therefore the ratio is 2:1 of 2 HCl : 1 X(OH)2 So using the equations mentioned above: Moles of acid is the number of moles= concentration X volume i.e. the volume will be used from the average Therefore: =0.05mol/dm3 x 19.675 cm3 =19.6 cm3 / 1000 = 0.0196 dm3 =0.05mol/dm3x0.0196 dm3 = 0.00098 moles So Moles of alkali in 25.000 cm3 Moles of HCl / 25.000 cm3 due to the ratio being 2:1, therefore 0.00098/2= 0.00049 moles of HCl So now the ratio is 1:1 so 0.00049 moles of X(OH)2 Moles of alkali in 100 cm3 It is assumed that there are four lots of 25 cm3 = 4 x 0.00049 = 0.00196 moles The next series of results will be used to calculate solubility of each compound by their mass in 100 cm3 The total Mr has been calculated in the table below for each compound. This was done by : Mr of X + ((O + H) X 2). Each element Mr for the following elements (OH)2 Total Mr Be 9.010 (16.00 +1.01) X 2 = 34.020 43.030 Mg 24.310 (16.00 +1.01) X 2 = 34.020 58.330 Ca 40.080 (16.00 +1.01) X 2 = 34.020 74.100 Sr 87.620 (16.00 +1.01) X 2 = 34.020 121.640 Ba 137.340 (16.00 +1.01) X 2 = 34.020 171.360 To obtain the solubility’s of metal II hydroxides is moles X Mr of the compound Therefore this table shows the calculation for the solubility’s for each of the different compounds Each element Total Mr Moles of X(OH)2 Solubiltity given as g/100 cm3 Literature values of the compounds given as g/100 cm3 Be(OH)2 43.03 0.00196 0.0843 0.000 Mg(OH)2 58.33 0.00196 0.114 0.001 Ca(OH)2 74.10 0.00196 0.0145 0.170 Sr(OH)2 121.64 0.00196 0.0238 0.770 Ba(OH)2 171.36 0.00196 0.335 3.700 Uncertainties: The uncertainty in measurement: Uncertainty due to pipette of 25.000 cm3 : Volume of X(OH)2 = à ¯Ã‚ ¿Ã‚ ½ 0.100 cm3 Percentage uncertainty = (0.1/25) X 100 = 0.400% Uncertainty due to Burrette of 50.000 cm3: Assumed due to measured volume of 19.675 cm3 and the uncertainty due to the smallest unit of measurement being 0.1 cm3 Therefore 0.1/2= à ¯Ã‚ ¿Ã‚ ½ 0.050 cm3 Percentage uncertainty = (0.05 /19.675) X 100 = 0.254% Therefore total uncertainty = 0.400% + 0.254% = 0.654% Conclusion and Evaluation: X(OH)2 is most likely to be Ca(OH)2 as the calculated solubility is closest to the literature value given of Ca(OH)2. The solubility for Ca(OH)2 0.145 g/100 cm3 and the literature value is 0.170 g/100 cm3. This shows that the difference is only 0.025 cm3. However the comparison between Be(OH)2 of the calculated solubility is 0.0843 g/100 cm3 and of it’s literature value 0.000 g/100 cm3 . Shows that there is a greater difference. Showing that it cannot be X(OH)2 solution. This is also shown for Mg(OH)2 as the difference between the calculated solubility and the literature value is 0.113 g/100 cm3, showing that it still has a greater difference than Calcium hydroxide does. The difference between Sr(OH)2 and it’s literature value is 0.532g/100 cm3. However the difference between the calculated solubility of Barium hydroxide and the literature value is 3.365 g/100 cm3 showing there is a great difference so it cannot be Barium hydroxide. The percentage error of Ca(OH)2 = [(0.170 – 0.145)/0.170] X 100 = (0.025/0.170) X 100 = 14.705% Throughout the experiment there were systematic errors and random errors that were met. Uncertainties/limitations Error Type of error Quantity of error Explanation for error Improvements Measurement in burette Systematic error +/- 0.05cm3 Equipment limitation, this is because the line where each of the reading might not be precise. Different manufacturer should be used with multiple trials in order to increase the accuracy of the calculated value to the literature value. Measurement in pipette Systematic error +/-0.1cm3 Equipment limitation, this is because due to the pipette only holding 25 cm3 of volume. The line could have been where the actual reading might not be Causing the result to not be precise. Different manufacturer should be used with multiple trials in order to increase the accuracy of the calculated value to the literature value. Point of colour change Random error Not quantifiable Human observation – subjective measurement. This is because even though a white tile is used, it is unclear as to what point has the solution gone colourless. Use alternative indicator for several different trials, use pH meter to assess neutralization point. Therefore there will be a more precise point as to when the solution becomes green. Temperature fluctuations Random error Not quantifiable There can be a change of measurements of equipment due to variation in expansion and contraction of materials. Due to the temperatures not being constant from the fan, windows or from the air conditioner. Controlled lab environment of the temperature by using a water bath at 180C with no air conditioner, fans working. To ensure no fluctuations occur. Fluctuations in humidity of room Random error Not quantifiable Change solution concentrations due to differences in evaporation rate in the surrounding air. Controlled lab environment Calibration error in burette Systematic error Not quantifiable 0 line incorrectly marked Divisions on burette inaccurate Use different manufacturer’s equipment for other trials Calibration error in pipette Systematic error Not quantifiable 25cm3 line incorrectly marked. Because it is unclear as to where the true meniscus lies. Causing the values measured out to be not precise. Also due to there being only one line causes a further decrease in the precision of the results. Use different manufacturer’s equipment for other trials to ensure that the accuracy increases. Another improvement that will be done, if the experiment were to be repeated is that due to the inaccuracy of the conical flask being swirled. If the conical flask is being swirled unevenly there is a chance of inaccurate results of when the colourless solution occurs. Therefore a stirring rod should be used to increase the accuracy of the swirls of the reaction in the conical flask. Another limitation that arouse in this experiment that would be improved if the experiment were to be done again is that after the neutralization reaction had occurred, there would still be some residue of the distilled water used to rinse out the equipment. This can be improved by increase the number of repeats of rinse. This would ensure that more of the diluted solution would have been removed. Also the trials can also increase, to 10 repeats so that there is more variance so that the accuracy increases. Another improvement might be, to use different indicator, for example methyl orange. Due to the colour change would be from red to yellow would make it easier for the pH 7 to be more easily recognized against a white tile then it was with phenolphthalein.

Case Synopsis Case Summary This paper describes and discusses the practical steps taken by Peter Senge in identifying â€Å"Why aren’t we all working for learning organizations?† The concept of an adaptive and generative learning organization is defined, and will discuss how organizational learning faces critical issues within its organization. First, the organization’s single-loop learning is discussed and reviewed. Second, the organization’s command and control structure is discussed whether it can be revamped to provide better attributes to an organizations learning. Last, the core paradigm is defined and discussed on its impact within the organization.

(Thomas Ely, 1996) This allows all races, nationalities, genders and etc. to feel a s though they are a part of this organization. The workplace paradigm can have a powerful production if employees were not scared to openly speak of their work related issues. Some of these issues could be a positive thing which could improve the organizational strategies, processes or practices. This article discussed how women and people of color were not treated with the respect that their white peers were given. (Thomas Ely, 1996) To this current day, this was one of the major learning issues within an organization. It’s changed for the better over the years but still faces some challenges. Conclusion What is clear from this brief summary is that there were many issues that our country faced of the learning organization. It took years to be able to reshape people’s way of thinking and behavior. There have been more trends were managers are listening to their employees on other ways to accomplish a task.
