Movement in education - Essay Example It is further stated that movement affects the brain which is activated during physical activity. The movement enhances the reading with utmost alertness, emotions are monitored and emotional intelligence is regulated through appropriate expressions. The movement also enhances the creativity by memorizing the past which can lead to self confidence. Children’s given physical education training so that their main movement center of brain remains activated enabling effective concentration during class hours. K-12 students are involved in creative topics enhancing their individual creativity. Physical activity is an important factor in building the students brain and physical fitness. Physical education is essential and should be made mandatory and part of the curriculum. All the schools in country should include various activities as part of the curriculum so that students don’t get sleepy sitting in the classroom. Physical activity like exercise, playing, creative development and all other activities apart from education which may build and develop brain’s activeness should be included in the curriculum. It was previously assumed that the physical and mental are separate and it is necessary to concentrate hard on books to be mentally strong. Further it was assumed that physical education may distract mental ability from the academic activity which was the main reason for reduction in recess and physical education in most of the school

Should Art Galleries or Museums or Heritage Sites Avoid Controversy or Essay

Should Art Galleries or Museums or Heritage Sites Avoid Controversy or Not - Essay Example Museums should steer clear of controversies. Controversies contribute to unnecessarily unfavorable images of the museum. The museums display artifacts representing different civilizations and cultures. Some quarters criticise the items displayed in the museum’s shelves. Controversies may unexpectedly appear. Individuals have different interpretations of the works of art. For a priest, nude painting is not an acceptable art alternative. The nude painting creates a vivid picture that the artist used a naked female model to finish the artwork. Museums should avoid controversies. Controversies trigger an unfavorable museum image. The word controversy equates to conflict. A conflict occurs when different sides have opposing views. Conflicts may lead to court cases. In other situations, a conflict creates animosity between the disagreeing parties. The news reports of controversies will not be good on the image of the affected museums. The above Rosetta Stone artifact is one example of a museum controversy. The controversy creates an unfavorable image that Our British Museum stole the Egyptian artifacts. In the controversy between the British Museum and Egypt, Egypt demands that the British Museum should return the Egypt artifacts. Egypt claims that Egypt is the owner of the artifacts displayed in the British Museum. This claim creates an impression on the public that the British Museum holds stolen property. Consequently, Egypt bombards the news outlets with statements that damage the reputation of the British Museum.   Further, the controversy states Egypt wants the Rosetta Stone returned to Egypt. However, our British Museum refuses to comply with Egypt’s demand. Similarly, Egypt insists that the Neues Museum should return Nefertiti’s Bust. The Neues Museum is located in Berlin, Germany.  

E-commerce Literature review Example | Topics and Well Written Essays - 2250 words

E-commerce - Literature review Example For instance, according to Jia-xin, Hong-xia & Jun (2010), it is estimated that one of four customers in China and 2 of three in Europe and Korea use e-commerce in making their purchases. However, despite all the benefits associated with e-commerce from both the perspective of the business and consumer, there are inherent challenges, which are affecting both the buyers and business in e-commerce platforms. Therefore, this literature review will focus on the advantages, disadvantages of e-commerce from both the perspective of consumers and business; look at the e-commerce market in the UK; examine culture of youth employment in UK and the Hofstede’s culture dimension and finally, the theoretical framework underlying e-commerce. According to Doolin et al. (2005), most consumers making their purchases through B2C consider it as a habit because of the popularity the method has gained as a new of way of shopping for goods in the UK, U.S.A, Asia and Japan. Moreover, Jia-xin, Hong-xia & Jun (2010) argues that, e-commerce is a convenient and easier way of shopping for goods because it is more flexible in terms of place and time. Therefore, this implies that as long as you are linked to the internet you can shop from any place or any time by going online to a business’s website store and make orders for goods and services. Thus, as consumer you will need not to stop working or get stuck in traffic as you go for in-store shopping. Conversely, e-commerce shopping provides comprehensive information about goods and services that are stocked by a business to consumers, hence, making them feel satisfactory and confident in purchasing such goods and services (Jia-xin, Hong-xia & Jun, 2010). That notwithstanding, e-commerce is less costly compared to in-store shopping because consumers will not have moving from one shop to another looking for goods or engage in bargaining negotiations with salesmen, thus, saving them traffic fees and transaction energy and

Improving operations Essay Example | Topics and Well Written Essays - 250 words

Improving operations - Essay Example The company uses enterprise resource planning (SAP) which helps in integrating the internal and external information and helps in quick response to the customer and improves customer relationship. The purpose of this management operating system is to share information among employees (Harwood, 2003). As the banking industry performance depends more on the individual performance of the employee and his/her ability to engage customers for a long-term relationship investment in the company. The organization uses the simplified idea management SIM process which effectively manages the productivity of the employees regarding innovation (Barton, 2010). The SIM process is implemented in each department of the bank because the model helps in better serving the customers and reduces cost for the organization. This process is necessary throughout the organization for continuous improvement and better growth (Barton, 2010). The SIM process is an effective approach in meeting customers’ needs and expectation because it allows employees to share information across all the organization about the customer’s desires and steps to ensure better customer satisfaction (Barton,

THE IMPACT OF THE HAJ EVENT ON VISITORS TOWARD THE HOSTING DESTINATION Research Proposal

THE IMPACT OF THE HAJ EVENT ON VISITORS TOWARD THE HOSTING DESTINATION - Research Proposal Example The evaluation of the event will be an essential attribute that requires a proper analysis and elaboration of the issues that take place within the same platform. This report proposes that the events profits the hosting country a lot due to the influx of people while also creating an opportunity for small scale traders to expand their business so as to gain from these events. The proposal will examine the different issues that affect attitudes when dealing with mega events. The proposal will evaluate the events and the value dimensions that define attitudes when dealing with such events. It will also look at the impact of having such an event to the hosting country as the costs and benefits will be felt most by the host countries. Most of countries have begun to open up on hosting mega events. The Hajj has always been an awaited session amongst the Muslims due to their religious connotations. Others have been yearning to host events as big as the fifa world cup and the Olympics because of the tourism benefits they accrue as a country (Horne and Manzenreiter, 2006: 190). The goal is to understand whether the benefits will outweigh the costs and whether the host country will manage the people who come to the country (Jones, 2001: 242: Daniels, 2006: 335). These have also shaped the world tourism patterns because everyone knows that the Hajj period is directed to Mecca and any world cup will be directed to the hosting countries. With time, people already shape their tourism patterns. They have also highlighted the new tourism destinations and brought new demands to these countries (Gelan, 2003: 410). The main expectation, however, is that the host country will have heavily invested in infrastructure, sporting facilities and security to avoid any fatalities due to the huge crowd (Szymanski, 2002: 170). The improvement will benefit the country afterwards, but the

Case Sharp Printing Essay Example for Free

Case Sharp Printing Essay Three years ago the Sharp Printing (SP) strategic management group set a goal of having a color laser printer available for the consumer and small business market for less than $200. A few months later the senior management met off-site to discuss the new product. The results of this meeting were a set of general technical specifications along with major deliverables, a product launch date, and a cost estimate based on prior experience. Shortly afterward, a meeting was arranged for middle management explaining the project goals, major responsibilities, the project start date, and importance of meeting the product launch date within the cost estimate. Members of all departments involved attended the meeting. Excitement was high. Although everyone saw the risks as high, the promised rewards for the company and the personnel were emblazoned in their minds. A few participants questioned the legitimacy of the project duration and cost estimates. A couple of RD people were worried about the technology required to produce the high-quality product for less than $200. But given the excitement of the moment, everyone agreed the project was worth doing and doable. The color laser printer project was to have the highest project priority in the company. Lauren was selected to be the project manager. She had 15 years of experience in printer design and manufacture, which included successful management of several projects related to printers for commercial markets. Since she was one of those uncomfortable with the project cost and time estimates, she felt getting good bottom-up time and cost estimates for the deliverables was her first concern. She quickly had a meeting with the significant stakeholders to create a WBS identifying the work packages and organizational unit responsible for implementing the work packages. Lauren stressed she wanted time and cost estimates from those who would do the work or were the most knowledgeable, if possible. Getting estimates from more than one source was encouraged. Estimates were due in two weeks. The compiled estimates were placed in the WBS/OBS. The corresponding cost estimate seemed to be in error. The cost estimate was $1,250,000 over the senior management estimate; this represents about a 20 percent overrun! The time estimate from the developed project network was only four months over the top management time estimate. Another meeting was scheduled with the significant stakeholders to check the estimates and to brainstorm for alternative solutions; the cost and time estimates appeared to be reasonable. Some of the suggestions for the brainstorming session are listed below.

Experiment on Size, Shape and Structures of Aggregates

Experiment on Size, Shape and Structures of Aggregates Introduction Dye sensitized solar cells (DSSC) have made considerable attention because of their unique features for conversion of free, unlimited solar energy into electricity by utilizing environmental friendly, inexpensive raw materials for low production cost1,2. DSSC composed of nanostructured, mesoporous semiconductors with wide-bandgap materials, to which the dye molecules (sensitizers) are adsorbed, a counter electrode and an electrolyte. In DSSC the dye molecule absorb visible light, and inject electron from photo-excited state of dye molecule to conduction band of semiconductor1,3 The performance of a dye-sensitized solar cell is mainly based on the structure of the visible light absorbing dye/ sensitizer. Applications of several natural carotenoid dyes with higher absorption coefficient in the visible region of the solar spectrum with higher conversion efficiency, is under investigations1,4. Carotenoids are C40 tertraterpenoid hydrocarbons consist of eight-C5 isoprene units5. The major characteristic feature of Car molecule is it comprises of extensive conjugated system of delocalized Ï€-electrons which makes them highly hydrophobic molecules. Therefore when these carotenoid molecules are dissolved in hydrated solvents they tend to form aggregates since the molecule is hydrophobic in nature. The surface arrangements and the aggregation behavior of the sensitizers (carotenoids) on semiconductor nanoparticles is greatly influenced the performance of carotenoid based artificial photosystems such as DSSC. It was stated (Wang et al.2006) that formation of dye aggregates suppresses the performance of DSSC6 since the device performance is influencing the nanoscale morphology of the aggregates. Therefore several researchers have focussed on the nanoscale organization of molecular aggregation in solutions of these conjugated molecules at atomic level resolution. Interchain agg regation behavior of a conjugated polymer (DP10-PPV) which used in opto-electronic applications such as pohotovoltaics, dissolved in two solvents having different qualities at different concentrations were studied by (Chen et al. 2009) using Small angle neutron scattering (SANS), revealed that the internal conformational structure of these network aggregates were differ in different solvents. A similar study was also carried out by Chen and coworkers for another semirigid conjugated polymer (DP6-PPV) in solutions7,8. Moreover it has been reported that, when carotenoid molecules are deposited on the surface of semiconductor often it forms H-shape aggregates5. Aggregation phenomena of natural and artificially modified carotenoids were proved that J- and H-aggregates are the possible geometries9. Apart from the formation of self-assembled aggregates in hydrated solvents of these carotenoid molecules, there is strong relationship between the structural conformation and the composition o f molecules in the solution with the ability of aggregation5. Polar carotenoids consist of –OH (hydroxyl groups) in the carotenoid structure promotes the formation of aggregates compared to the molecules without any functional groups, (Simonyi et al. 2003). Furthermore the position of the functional group may also significantly affect the type of aggregates form10. It was observed experimentally for the first time (Cheng et al. 2009), the crossover from swollen coils in semidilute regime to unperturbed coil at high concentrations11 with the variation of polymer radius of Gyration (Rg) of poly(methyl methacrylate) in chloroform as a function of polymer concentration (à Ã¢â‚¬ ¢). Perahia et al. used SANS data12to investigate how molecular solutions of poly(2,5-dinonylparaphenylene ethynylene)s (PPE) aggregates into large flat clusters. Ratnaweera et al. 2012 and Lodge and coworkers were studied self-assembly modes of several block copolymers in selective solvents using SANS13 -15. Therefore the studies of dye aggregates are really essential for future developments of carotenoid based electrochemical devices for solar energy conversion. Spectroscopic studies on carotenoids in hydrated solvents revealed that the aggregation behavior of carotenoids is significantly affecting the S0 →S2 electronic transition16 of neutral carotenoids. Therefore the solvent quality is one of the major factors for carotenoid solutions which govern the size of the aggregate. When the carotenoid molecules are uniformly dissolved in a good solvent at low concentrations to form a homogeneous mixture, carotenoids are exist as isolated molecules that are very far from each other17. Therefore the interactions between monomers are very weaker than the monomer-solvent interactions and polymer tends to swells and its size is larger than the ideal size13,18. Cheng coworkers stated11 that in the good solvent domain (T > ÃŽ ¸), the repulsions of excluded volume is greater which results Rg of the aggregates enhanced beyond its unperturbed size. Further this expansion effect is greater in dilute solutions since the volume fraction of polymer is very low compared to its overlapping concentration. When the concentration of the solution is increased, the attraction between monomers are stronger and the aggregates tried to collapses into globules wit h solvents inside it corresponds to a poor solvent. The size of the structural conformation of collapsed globule is smaller than the ideal chain17. For a polymer solution (NA = N and NB = 1) to be favorable for mixing or aggregation is depends on the Flory-Huggins equation which consist of two terms, the entropy and energy terms17. The energy change of binary mixing which depends on composition of the mixture is the main factor, for a polymer to be dissolved in a good solvent to make an equilibrium state of a homogeneous mixture of polymer solution. Entropy of mixing is small for polymer solutions and always positive hence promotes mixing, but the energy of mixing is either positive or negative which measures the attractive or repulsive interactions between species. The net attraction between species in the solution is important because it measure the value and the sign of the Flory interaction parameter (χ) and hence to know whether the given mixture consist of single-phase or separated into phases. In this research the small angle neutron scattering (SANS) data was used to investigate the quantitative experimental information on size, shape and structures of aggregates. Two carotenoid molecules, bixin and norbixin were selected in this study to characterize their structural information of monomeric and aggregated forms. The natural dyes, bixin and norbixin are belongs to the group of apo-carotenoids, extracted from annatto seeds of the Bixa orellana tree1. The chemical structures of cis-bixin (C25H30O4) and cis-norbixin (C24H28O4) is shown in fig. 1. (1) Gà ³mez-Ortà ­z, N. M.; Và ¡zquez-Maldonado, I. A.; Pà ©rez-Espadas, A. R.; Mena-Rejà ³n, G.
