Parenting styles vary per different stages of life. Our parentÃ¢â¬â¢s behavior changes when we grow. In the younger ages, parents donÃ¢â¬â¢t expect much from their childrenÃ¢â¬â¢s because children lack the experience to handle specific parts of life. Other aspects that affect the parenting styles is money. Financial status plays a key role in the parenting style. Working class parents use authoritative style and they give their children more independence but on the other hand financially strong parents use authoritarian style and they closely monitor their childrenÃ¢â¬â¢s development Miller (Dec 2015). The fact that a parent is single or married also plays a big role in parenting styles. Children of single parent are more likely to steal or lie compared to married couples. Children with parents who are divorced or separated were more likely of anger issues, poor academic performances and bed wetting. A step-father or step-mother can be more permissive to their step-children i n order to gain their trust because permissive parenting involves a lack of demands and expectations, Jinnah (July 2016). Children raised by parents with this style tend to grow up without a strong sense of self-discipline. They may be weak in school due to the lack of boundaries in their home, and may be less academically motivated than many of their peers. Since these parents have few requirements for mature behavior, children lack skills in social settings. While they are well at interpersonal communication, they lackShow MoreRelatedThe Evolution of the Family Systems Essay659 Words Ã |Ã 3 Pages Family Systems The word family in the 21st Century has a much different meaning no than it did even 20 or 30 years ago.

In previous decades one of the most evident modifications in U.S. agriculture has remained in agricultural input markets. The exceptional development in yields and agricultural total factor productivity owes much to biological innovations in crop seeds, development of hybrid crops in the early part of the 20th century, with adoption of high-yielding varieties and modern biotechnology. Development of new types of pesticides and seeds has substantially improved agricultural productivity (). Agricultural input markets have evolved and familyÃ¢â¬âowned and other small businesses gave way to larger enterprises that integrated in plant breeding, conditioning, production, marketing, and other functions. The evolution in the industry was coupled with increasing market concentration in seed and chemicals supply, and widespread mergers and acquisitions further shaped the industry. These dramatic changes have raised significant concerns regarding market power and its influence on agriculture , in general (). These mergers are fueled by the need for increased research and development budgets. Agribusinesses are trying to develop crops that are resistant to climate change as temperatures around the world grow hotter and rainfall grows more erratic. TheyÃ¢â¬â¢re also going to have to feed a lot more people; by 2050, projections show there will be 9 billion people living on the earth. This means there is going to be less area to farm.

Benefits of the variance analysis/ standard costing Paper There are several benefits of the variance analysis; the variance analysis compares actual costs against budget. If actual performance is better than standard there is said to be a favourable costs variance. E. g. If standard labour cost is 36 but actually works out to beÃ 32 theres a favourable difference ofÃ 4. This means that the costs are lower than expected. However if actual performance is worse than standard this is said to be an adverse or unfavourable variance. Variances are a method of control and can show if the firm is running efficiently. Variances can also be a motivating factor for the staff as if an adverse exists staff must work hard to change the adverse into a favourable in the future. Variance analysis is also classed as a method of appraisal as staff can easily know if they have done well when the variance is favourable. Staff can monitor their progress and assess how well they are performing. Variance analysis helps and is a tool of, Planning function. Control function. Motivating function The variance analysis can be used on any expenditure of the business. There are a number of advantages of using this techniques.

If a variance appears to be too high than it can be investigated using an approach called management by exception. This can allow tolerance in the control system. Some firms only investigate variances if they are more than 5 to 10% different from the standard . Disadvantages of the variance analysis/ standard costing It can be difficult sometimes to forecast as obtaining the numbers can be difficulty and costly. Variance analysis can also de motivate staff as it could restrict permanent improvements as the worker might achieve goal and not do more. Variances could also restrict the idea of continuous improvement as just meeting targets and not doing more could de motivate staff and company performance. In some cases to carry out standard costing it can require a business to gather large amount of information. The process can be time consuming and in some cases expensive. Most firms use standards costing as an ongoing process so the costs are ongoing. There are some unforeseen consequences with standard costing. A member of staff in order to achieve a favourable variance might purchase cheap poorer quality materials. This would bring the costs down but it could effect sales as product made with poor material. This could damage the reputation of the firm and losses as low sales. The variances have occurred due to many factors such as the decline in sales, material costs, labour costs and even the marketing of the product. The variances have occurred as the market is in decline and the firm is only aiming its product at the older segment and not at the younger age as they are more interested in computer games. The product is not targeted at the new market but only for those in there 40 60s. Another cause that I believe has resulted in the poor variances is the special order being lost probably due to the firm not meeting production deadlines so as a result the variance has occurred. I believe is the main reason why the variances have occurred and this is because of the machinery is said to be old and not reliable and also the variance targets could be set too high or even too low so this must be investigated to a further extent. The material variance resulted in an adverse this is probably due to the price of the material, the price of the materials could have increased so firm should of searched out for a new cheaper supplier. The budgeted amount was 490 whilst the actual amount was 342 so there was an adverse of 58. More material was used than predicted this I think was probably due to a lot of wastage or even workers making mistakes and wasting materials. Another reason for this variance could be the theft of the material. I think the firm did not take advantage of bulk buying so major discounts were lost and could have resulted in the adverse variance. The material costs could also have been budgeted too low and the firm did not realise the increase in prices, wastage so this could have also hindered the variance. The labour variance also showed an adverse, as the budgeted was 96 whilst the actual came to 105 meaning an adverse of 9. This is another adverse in the firms variance analysis and is caused by the ageing workforce I feel. Most of workers are in their later age and could suffer form illnesses. The main reason I feel the variances have occurred is due to the old machinery the firm owns as it could have broken down and valuable man-hours had been lost whilst the machinery was being fixed. Labour time management and training could also have occurred the variances as the workers could be poorly trained and could not carry lout the tasks in the required times. The power variance is shown to be a favourable in the analysis as budgeted was 4. 8 and actual was 4 so a favourable of 0. 8. This is a positive variance but it is only achieved as the firm has only produced fewer goods as machinery kept on breaking down. The variance could also have been set too low so even as this is a positive variance it musty still be investigated as why it has occurred as a positive. The fixed production cost variance is a favourable by . The budgeted amount was 50 whilst the actual came to 48. This has occurred probably due to good management or even a reduction in fixed costs. If a firm keeps its fixed costs too low they might be emitting vital functions of the business that could reduce the firms efficiency and in return could suffer high costs to the business in the loss of productive efficiency and sales by keeping fixed costs deliberately low. On the bases of my variance analysis I will recommend the following suggestions to the firm so the variances could be minimised. In order to minimise the variances the firm must recognise its operations. The sales variance was relatively high so the firm needs to concentrate and improve the marketing effect. The firms could take such actions as an increase in its advertising campaign, so it is increasing the knowledge of its product. To improve the variance the firm could target a new segment the younger generation with newer model cars and benefits. By effective marketing research and approach the firm should target new customers who would want these benefits. The firm main aim should be effective marketing especially at the newly identified 40 to 60 year olds. Ongoing marketing will increase potential sales thus higher profits can be achieved. The firm is selling nostalgia so variances could be achieved through effective management and by improving standard costs and the overall efficiency of the business. The firm must ensure that the budget costs are equal to actual costs and this can by done effective market research and planning that will result in a efficient firm. All extensive favourable variances that have occurred I feel must be investigated as they could have been set too low and the firm did not budget effectively. The firms number one aim should be to enforce accurate budgets and team working, training and also investment into new machinery and the results will show up in profits. Cellular production could also be used to create job deepening and widening as a result the average work day will became more interesting and worker will work more effectively and also less absentees. By training workers and working effectively the firm would benefit from correct budgets and profit. Bulk buying and extensive market research is vital to successful and must be fully met. I will now construct a sales forecast for the next year. Jan Feb March April May June Low low increase 10000 10000 15000 18000 20000 30000 July Aug September October November Decline high 20000 25000 25000 51000 80000 Dec Total 388800 for year predicted are. High 84800 I came to the above sales forecast conclusions that I have created y referring to the appendix 2 in case study that I had. By using the sales variance I have predicted that that sales will fall. The sales forecast above are my predictions but I have also taken into account the declining market, as children are less interested in toys and more in computer games. So I have decided to have a 10% decline in the sales predictions. I have taken 10% of the original sales prediction of 432000 from last year. The new total I have come to is 388800. A 10% decline. Later on sales that I have predicted should increase as the firm has identified the new market of 40to 60 years olds who are interested in model cars and also the exporting form Taiwan could help the increase of sales. Ensuring that the above recommendations made by me are taken into account. Of effective marketing and management, the control of budget, thus the sales should increase. I must reiterate that marketing should be an ongoing process so the consumers can be informed of what is new and available. The highest sales will be made at Christmas due to the festive season. This is the time of the year where JCC needs to get its marketing policy precise as most firms take advantage of the holiday season and launch many products. At the beginning of the year the sales are very low but gradually they will increase this would be due to the firm employing effective marketing and attracting a new segment. Based on the figures presented in appendix 1 I will calculate the monthly profit using marginal costing.

The Classic 1972 Summit Series Essay Essays The Classic 1972 Summit Series Essay Essay The Classic 1972 Summit Series Essay Essay The 1972 Canada-Soviet Hockey Series was possibly the most dramatic athleticss event in Canadian history. Before the series came into being. the SovietÃ¢â¬â¢s demonstrated that they were a tower of strength by winning 11 of 12 Olympic and World Championships from 1963 to 1973. However. Canadians believed that the Soviets would lose to Canadian professionals. The 1972 Super Series was the chance for CanadaÃ¢â¬â¢s Ã¢â¬Å"bestÃ¢â¬ to turn out their laterality over the Soviets. Charles Hay ( President Hockey Canada 1972 ) was quoted by stating. Ã¢â¬Å"At long last we are disputing the Soviets with a squad of CanadaÃ¢â¬â¢s best hockey participants. and portion with all Canadians our pride in being represented by this superb group of immature work forces playing our national game. Ã¢â¬ This series would set the Soviet Ã¢â¬Å"amateursÃ¢â¬ against CanadaÃ¢â¬â¢s professionals. It has made a immense portion of history in Canadian hockey and will be remembered for old ages to c ome. The dramatic series consisted of an eight game series with four games being played in Canada and four games in Moscow. Unfortunately. the Soviets came out of Canada with a little lead in the series and headed back to Moscow for the following four games with place advantage. After losing the first game in Moscow. this put Canada in a tough place to win the following 3 games to win the series. Brian McFarlane from Hockey Night in Canada quoted. Ã¢â¬Å"I still experience Team Canada has superior single participants. Their corporate experience. and more than that their pride. will force them to triumph. But they must non take foolish punishments. Fast line alterations and consistent bow checking are the keys. particularly against participants like Kharlamov and Petrov. I think weÃ¢â¬â¢ll hold a little border when itÃ¢â¬â¢s all over. Ã¢â¬ The Canadians did in fact win it and that is why this unbelievable series played by two great squads made it such a memorable event. How could people bury the great goaltending Vladislav Tretiak provided for the Soviets! Or even the barbarous cut that Bobby Clarke laid on the Soviets star participant Valeriy KharmalovÃ¢â¬â¢s mortise joint! Besides who could bury Phil Esposito endangering the referee with his stick! One memory that will neer be forgotten would hold to be when the Canadian participants had to deliver Alan Eagleson from the boisterous Soviet fans! All of these particular minutes that happened during the series assisted in doing this event a particular classic. This 1972 Super Series was and still is a authoritative. Similar to a authoritative novel or film. people remember the stoping. Paul HendersonÃ¢â¬â¢s winning end ended the 8th game winning the series for Canada. This made him a national hero. There are other illustrations that made this a authoritative series. Recently. the media took advantage of this series and made a particular Television series about it. There is besides a DVD made to advance the 1972 series. The one chief thing that makes it a authoritative is that people still talk about it 35 old ages subsequently merely like it happened yesterday. When one thinks of great international hockey. conversation normally comes up about the 1972 Super Series between Canada and the USSR. Charles HayÃ¢â¬â¢s quotation mark in the debut paragraph negotiations about how Canadians had high outlooks for the participants that represented Canada. Canada did win the series. but it brought on a high regard for Soviet hockey that was non at that place earlier. The 1972 series was an electrifying spectacle of all time to blossom in Canadian spheres and got infinite 1000000s to watch the two states conflict it out. This series created an intense competition between Canada and Russia. which is still present to this twenty-four hours. Recently. the Canada/Russia competition continued with an eight game series between the best junior participants from each state. There was an effort to retroflex the authoritative 1972 series. but the ballyhoo was merely non at that place and most likely neer will be. The Canadians won this series rather conveniently. As people had high outlooks for the 1972 squad to rule the Russians. the 2007 squad showed great accomplishment and that they were the better squad. Everyone knows that the 1972 Super Series is a authoritative. and ever will be a great authoritative. Bibliography 1. Littler. H. ( 1974 ) . 1974 Canada Vs Russia. Toronto: C. A. H. A.

List of Elements in the Transition Metal Group The largest group of elements on the periodic table is that of the transition metals, which is found in the middle of the table. Also, the two rows of elements below the main body of the periodic table (the lanthanides and actinides) are special subsets of these metals. These elements are called transition metals because the electrons of their atoms make the transition to filling the d subshell or d sublevel orbital. Thus, the transition metals are also known as the d-block elements.Ã Here is a list of elements that are considered to be transition metals or transition elements. This list does not include the lanthanides or actinides, just the elements in the main part of the table. List of Elements That Are Transition Metals ScandiumTitaniumVanadiumChromiumManganeseIronCobaltNickelCopperZincYttriumZirconiumNiobiumMolybdenumTechnetiumRutheniumRhodiumPalladiumSilverCadmiumLanthanum, sometimes (often considered a rare earth, lanthanide)HafniumTantalumTungstenRheniumOsmiumIridiumPlatinumGoldMercuryActinium, sometimes (often considered a rare earth, actinide)RutherfordiumDubniumSeaborgiumBohriumHassiumMeitneriumDarmstadtiumRoentgeniumCoperniciumÃ presumably isÃ a transition metal. Transition Metal Properties The transition metals are the elements you normally think of when you imagine a metal. These elements share properties in common with each other: They are excellent conductors of heat and electricity.The transition metals are malleable (easily hammered into shape or bent).These metals tend to be very hard.Transition metals look shiny and metallic. Most transition metals are grayish or white (like iron or silver), but gold and copper have colors not seen in any other elements on the periodic table.The transition metals, as a group, have high melting points. The exception is mercury, which is a liquid at room temperature. By extension, these elements also have high boiling points.Their d orbitals become progressively filled as you move from left to right across the periodic table. Because the subshell is not filled, atoms of the transition metals have positive oxidation states and also display more than one oxidation state. For example, iron commonly carries a 3 or 2 oxidation state. Copper may have a 1 or 2 oxidation state. The positive oxidation state means the transition metals typically form ionic or partially ionic compound s. Atoms of these elements have low ionization energies.Transition metals form colored complexes, so their compounds and solutions may be colorful. The complexes split the d orbital into two energy sublevelsÃ so they absorb specific wavelengths of light. Because of the different oxidation states, its possible for one element to produce complexes and solutions in a wide range of colors.Although the transition metals are reactive, they are not as reactive as elements belonging to the alkali metals group.Many transition metals form paramagnetic compounds.

The Role of International Systems - The Balance of Power During the Cold War - Essay Example In itself, the balance of power theory suggests that any rapid change in the international status or power of an independent state or collection of states will result in counterbalancing actions by other states. This occurs most readily when the alliances between different states are easily broken and formed based on what is beneficial to the particular state at the time. This essay argues that the balance of power was a key factor in the Cold War and was the driving factor of many of the events that occurred, including the Cuban Missile Crisis. Furthermore, this ultimately resulted in the development of the unipolar international system that is present today. The theory of the balance of power differs substantially between authors and publications and this section will attempt to determine some of the overall themes. Some authors consider that the model is a description of the international systems that are in place currently, others consider that it is a theory of coalitions, while still others consider it a guideline to peace2. In one sense, any international system is a balance of power relationship at some level. However, the term is usually used to refer to specific systems where the actors respond to each other primarily through negotiation rather than through war and where they each attempt to protect their stateÃ¢â¬â¢s short-term and long-term interests3. Each country has their own internal resources and interests which they aim to maintain, as well as their position on the international stage, their relationship to other international powers and international trading relationships. States must balance their internal needs with needs of the international environment. Regardless of exact definition, the balance of power remains one of the most central theories of international systems and relations.
