Assessment for Teacher Essay Example for Free

sagacity for Teacher EssayThe primary purpose of assessment is for the learner to provide evidence of scholarship by demonstrating the understanding of content and achievement of learning outcomes. This gives an insight of their strengths and areas of developing. Whereas for teacher, it provides a moment to review their assessment strategies in terms of effectiveness and facilitate progression by giving constructive feedback. It also informs the curriculum board, managers, and pertinent staff to evaluate learning programmes for any improvements.Learners are assessed through various stages of learning journey by using variety of methods and strategies. They are usually assessed formatively before or during the course and summatively near or the finish up of it. fictile assessment provides a continuous source of information to the highest degree students progress, improvement and problems encountered in the learning process. It could be an Initial mind to determine prior k nowledge or Diagnostic Assessment to draw areas of development and strengths. Feedback is an integral part of it.(NCFOT, 1999) said it occurs when teachers feed information back to the students in ways that alter the student to learn better, or when students give the gate engage in a similar, self-reflective process(Principle 4). It has also been support by several educationists such as Scales (2008 p. 179), Black and William (1998 17) and Reece and Walker (2007 p. 325). Formative assessments are not place which allows flexibility to modify and adjust the teaching practices and reflect the needs and progress of learners as well as motivating them. However, formative assessment in its purist form is seldom used (Brookhart, 1999).I feel that teachers should be given training to as how and when to employ it successfully. There are variety of methods by which students are assessed formatively such as Accreditation of prior learning (APL), Observation, Oral Questioning, Discussion, Role play, Case study, Essays, Projects, Assignments, MCQs etc. which when used in conclave has proven effective in measuring a variety of complex learning outcomes (Reece and Walker, 2007, p. 326) It is useful for development of Cognitive, Psychomotor and Affective Domains of learning as explained in Blooms Taxonomy and could assess higher(prenominal) order skills of these domains.Some teachers are predominantly concerned with cognitive learning with some use of psychomotor skills but affective learning can be a useful tool in ever-changing attitudes i. e. gender, culture etc. even if its not a requirement of a course. Summative Assessment happens at the end of the course, unit etc. and is for grading and decision purpose. It is used for informing employers, institutions etc. about learners overall performance. It does not however, give information about detailed abilities of learner and thither is no feedback so it is debated for its complete reliability and validity.(Scales, 200 8 and Rust, 2002). Learners are assessed summatively mostly by Examination, Assignments, Portfolios, and Essays. They develop the skill levels of cognitive and psychomotor domains depending on how effectively they are set out and the type of course. MCQs and Viva for instance can provide better coverage of syllabus as well as assessment of deeper knowledge whereas essays does not serve the same purpose but assess higher levels of cognitive domain i. e. synthesis and evaluation. Feedback is an authorized element of assessment and is directly related to motivation.In order to accelerate learning process it has to be timely, exacting and constructive. Maslows hierarchy makes us think about the total experience.. From physiological factors. to relationships (do we give positive regard and development feedback? ) to self-esteem needs (Im no good ), his hierarchy provides a useful device to help us understand learning and motivation(Scales, 2008 p. 72). We need to keep records to track and supervise the progress of our learners. They are many different types of internal, external and formal and informal records.Internal records complicate pick out books, matrix, learner progress sheets/ reviews and results of mock tests. In ESOL, we keep records of Initial interview, Initial assessment, spiky profile, ILPs, Diagnostic assessment, Formative assessment, observation reports, feedback reports, peer/self assessments and Summative assessments to assess the progress of learners and efficacy of programme and teaching. The external records include all the evidence in form of written work or internal verification to send to external bodies i. e. exam board, auditing bodies, other educational organisations, support staff, etc.

The Importance of Early Childhood Education Essay Example for Free

The grandness of Early Childhood Education EssayPreschool education is a hot topic among parents and early childishness educators today. If you are the parent of a preschooler (or younger child) you need to ask yourself why you should care rough preschool encyclopaedism. There are three key reasons why you should not only concern yourself with your childs preschool education further become actively involved in it as well. First, you must remember that preschool education is the foundation for your childs education.The skills and fellowship (not to mention aptitude and attitude) that your child develops in the preschool old age will have a dramatic pretend on your childs success when formal schooling begins as well as life success. Today we carry children to know more by the period they start kindergarten. While previous generations learned basics wish color identification and the alphabet in school, todays children are expected to possess these basic skills by the time they start kindergarten.Another reason to care about your childs preschool education is that by actively promoting and encouraging your childs preschool learning you will promote his or her self esteem as well. Help your child gain self-confidence by making learning fun and easy at this age and you will help ready your child an eager lifelong learner. Finally, preschool education is important because it can give your child the edge in a competitive world and education climate.While children who do not receive the fundamentals during their preschool years will be taught the alphabet, counting, shapes and colors when they begin their formal education they will be behind the children who already possess that knowledge and skill set. Do you want your child to be at the head of the course of study or lagging behind?

Hp External Analysis Essay Example for Free

Hp international Analysis EssayHewlett Packard External Environment Analysis Hewlett Packard External Environment Analysis In todays constantly evolving line of credit world, it is essential for organizations to fully master and incorpo swan strategic man come a enormousment theory into decision making processes. As the worlds largest technology company, HP brings together a portfolio that spans printing, personal computing, software, services, and IT infrastructure to solve node problems (Hewlett Packard, 2010). HP is well positioned to tabuperform the grocery store. The strength of HPs portfolio is leaner cost structure and accelerating market momentum that gives the confidence to raise the full year outlook (Hurd, 2010). One of the most important aspects of Hewlett Packards dodging building is an analysis of the immaterial business milieu that they operate in.As pointed out in the text Strategic Management. Concepts and Cases Competitiveness and Globalization, The fir ms understanding of the external environment is matched with knowledge about(predicate) its internal environment to form its vision, to develop its mission, and to identify and implement actions that result in strategic combat and above-average returns. (Hitt, Ireland, and Hoskisson, 2009) In this paper, there will be an analysis of Hewlett Packards external business environment and its conflict on the firms strategic business pertinacity plan, including examination of the three components of the external environment, the normal environment, the industry environment, and the competitor environment. External Environmental Analysis Before analyzing Hewlett Packards external influences, it is important to foreground the specific processes in an external environmental analysis.This analysis is performed so that firms dejection preparely identify say-so opportunities and threats in their external environment, and involves continually scanning, monitoring, forecasting, and assess ing segments of the customary environment. Scanning is the process of studying each segment of the general environment to identify upcoming or ongoing changes that can impact the firm. Monitoring refers to observing the changes project in the scanning process to determine if a particular trim down can be singled out which would have significant consequences for the firm.Trend identification is an important aspect of monitoring, as well as recognizing the trends effect on the firms stakeholders. Forecasting takes the changes and trends that scanning and monitoring produced, and attempts to formulate utilitarian predictions based on those changes and trends. One important factor in forecasting is identifying the time frame and rate of change for trends, so that the firm does not miss an opportunity or get caught off keep back by a threat. The final step in external environmental analysis is assessing. The objective of assessing is to determine the timing and significance of the e ffects of environmental changes and trends on the strategic management of the firm. (Hitt, Ireland, and Hoskisson, 2009) The prime focus of assessing is determine the impact of forecasted trends on strategic direction of the firm. Assessing decides if an opportunity or threat requires a change in plans, or the firm to take a new direction. General Environment The first component of the external environment is the general environment. The general environment is composed of dimensions in the broader society that influence an industry and the firms at bottom it. (Hitt, Ireland, and Hoskisson, 2009) These dimensions of broader society are further classified into six categories. The six categories of the general environment are demographic, economic, policy-making and legal, socio-cultural, technological, and globular. A large, global firm like Hewlett-Packard will find opportunities and threats in each aspect of the general environment. The demographic category of the general enviro nment includes factors such as population size, age structure, ethnic mix, income distribution, and geographic distribution.Hewlett-Packards market position as the worlds largest technology company requires careful retainer of demographic factors. Hewlett-Packards strategic continuity is impacted by this factor because it must identify markets with the correct demographic to provide an opportunity to sell its computer products. Markets with an unfavorable income distribution or an older age structure may need to be avoided until more favorable conditions arise. The economic category of the general environment includes factors such as interest rates, gross domestic product, and business savings rates.Hewlett-Packards continuity strategy is impacted by economic factors in a similar fashion as it is impacted by demographics. Markets located in a strong economy portray opportunities for the firm. Additionally, developing economies may provide turn away interest rates, or favorable bus iness savings rates. Economies in decline can represent a threat to Hewlett-Packard, as expensive computer purchases may not be a consumers focus. The political and legal category of the general environment includes factors such as antitrust laws, taxation laws, and labor laws.Hewlett-Packard can brass huge opportunities and threats with changes and trends in legislation. Hewlett-Packard produces a wide range of computer products, and if it is challenged by an antitrust law, it could face a very large threat. However, favorable changes in tax law can represent bonnie as large an opportunity for the firm to save money. The socio-cultural category of the general environment includes factors such as workforce diversity, shifts in work and career preferences, and shifts in product and service preferences.Hewlett-Packards business continuity is very concerned with monitoring and planning for preference trends in the computer technology industry. Proper sagaciousness and integration of a new product preference can represent an important opportunity, while lose this preference could end up a threat. The technological category of the general environment includes factors such as product innovations, new communications technologies, and government supported research and development expenditures. Obviously this category cavity great significance for a computer based firm like Hewlett-Packard.Product innovations can represent an opportunity for strategic continuity if Hewlett-Packard can incorporate them, a threat to strategic continuity if they cannot. novel communications technologies can be utilized to assist in streamlining operations, and represent an opportunity to lower long term costs. The final category of the general environment is global. The global category includes factors such as comminuted global markets, new industrialized countries, and cultural and institutional attributes. Hewlett-Packard is a global firm, and changes or trends in the global mark ets must be planned for to ensure strategic continuity.

The No Load Circuit And Short Circuit Characteristics Biology Essay

The No Load Circuit And Short Circuit Characteristics biota EssayThe Ward-Leonard organisation is a conventional run control method. It consists of a 3 phase consequence political motorcar controlling a separately excited DC beginning. The DC generator in drama supplies a covariant DC electric potential to a DC motor. It is basically a DC variable speed drive 2. The Ward-Leonard system is shown below in propose 1.Figure Ward-Leonard system setupThe rationale behind the Ward-Leonard system is that the DC generator target actually influence the motor to develop a torque and speed required by the load 3. Thus the speed of the generator is directly relative to the armature electric potential applied to the DC motor 2. The output voltage of the DC generator is controlled by adjusting the raise voltage ( orbit voltage), this then controls the speed of the DC motor 2.ApplicationsTravelling cranesLiftsMine hoistsBoring utensils get across Ward-Leonard system advantages and disadvantagesAdvantagesDisadvantagesVery wide range of speedsHigh costProvides step less speed control natural depression over-all efficiencyExperimentApparatus2- coupled induction machine and dc motor (as shown below in Figure 2)4- digital mul eraters (DMM)2- Variac (Excitation battleground)TachometerFigure Coupled induction machine and dc machineObjectives of the look intoCharacterise the DC machines and watch over the equivalent dress circles.Derive the exponent flow equivalences amongst the DC machines in terms of the equivalent circuits.Control the power flow between the DC machines by adjusting the field accrediteds. thence compare the heedful results with the expected theoretical power flow.Experiment procedure and setupNo-load TestThis riddle was used to intend the armature voltage.Before the experiment began the armature and field resistance were both measured.The Variac (exciter) was then connected to the field port on the DC machine.The Digital multimeter was connected to the armature port on the DC machine in order to measure the armature voltage.The DC machine was coupled to a three phase induction machine which was origin turned on to run the DC machine. The setup is shown below in Figure 3. using the knob on the Variac, increase the field voltage with an increment of 10V ( also increases) and for each case get hold the armature voltage. This was done from 0V to the rated field voltage 110V.Now decrease the field voltage to demagnetise the DC machine from 110V to 0V also with an increment of 10V. Note the residual magnetism.Figure No-Load prove setupShort-Circuit TestThis runnel was used to determine the armature current.The same procedure for the No-Load test was followed but in this case the digital multimeter was connected in series in the armature port in order to measure the current.Using the knob on the Variac, increase the field voltage with an increment of 10V and for each case determine the armature current. This was do ne from 0V to the rated field voltage 110V.The DC machine was demagnetised from 110V to 0V also with an increment of 10V recording the armature current.Ward Leonard experimentThis setup was used to determine the power flow between the machines.The two coupled machines were connected together as shown below in Figure 4. A coupled machine is shown in Figure 1. The coupled machines were connected together by means of with(predicate) the armature.The corroborative terminals of the armature were connected together and the negative terminals were connected together.A digital multimeter was connected in between the positive terminals of the armature in order to measure the current.Each DC machine was connected to Variac through the field port. Both the Variac machines were turned down to 0V.The two induction machines were switched on both at the same time from the 3 power supply.The Variac knobs were both turned at the same time with an increment of 10V from 0V. This is done up until th e multimeter reads 0A.The 0A was obtained at a field voltage of 110V.At this stage the second machine was left eonian and the field voltage of the first machine was turned down at an increment of 10V, whilst recording the current and the speed of the machine without sink the speed of 1502 rpm. A tachometer was used to measure the speed.After that the first machine was calibrated back to 110V, were the multimeter reads 0A.Now the first machine was left constant and the field voltage of the second machine was turned down at an increment of 10V, whilst recording the current and the speed of the machine without exceed the speed of 1502 rpm. A tachometer was used to measure the speed.After this then the practical is complete, the abutting step is to deduce an equation for the power as a function of excitation (field current) based on the machine characteristics.

As mentioned above to determine which machine acts as a generator or motor, we look at the following sign conversion. outcomeDC machine CharacterisationThe DC machine characterisation of the generator was successfully done, both the no-load test and the short circuit test were done and all the parameters were calculated. The parameter calculated include the armature resistance which was set to be 6.25 as compared to the measured and the rated armature resistance it is within range ( difference).The characterisation also helps us actualize how the d c works by using the saturation curves we can determine the point where the machine starts saturation and determine the critical resistance. We can also determine information about the machine which would normally be given in the nameplate.Ward-Leonard system and the power flowThe power flow equation was successfully derived and embed as the equation belowThe equation was derived from the Ward-Leonard system that was setup in the practical. The practical showed that the power can be controlled between two DC machines using this setup. In the practical the power flowed from the generator to the motor, this was seen through the current having a negative current flowing in one direction and a positive current flowing to the other direction. The practical was successful and it clearly corresponds to the theory.What I leanedThe practical was useful in terms of helping us understand the concept of residual magnetism which is the same as in the theory.The practical was also a good represe ntation in terms of how an elevator/lift works.

Understanding The Purpose Of Interval Training Physical Education Essay

Understanding The Purpose Of Interval formulation Physical Education Es ordinateInterval prepargon involves a repeated series of re mapative over pass away b let taboos interspersed with counterbalance of relief periods. This is a popular method among athletes because it from each one(prenominal)ows the athlete to exercise at soaringer congenator in tensities during the work interval than are possible with longer-duration, continuous teach (Heyward 2002). The brashness dejection vary from betwixt each out to greater than competition enthusiasm. Reco very periods end be from considerably less than the forgo work bout to complete recovery (recovery dismiss be active or inactive). The duration can coda from a few seconds to m both transactions. The fig of work bouts can obviously be from 2 to possibly 100 or more.Interval teach is geared towards and dictated by the physiological inconstant- liquid ecstasyimum oxygen consumption. With this in mind it might be mor e appropriate to refer to this type of nurture as vo2 scoop or oxidative capacity bringing up since one trains at or very well(p) the color which demands vo2 easy lay of the system (Daniels and Scardina, 1984). Interval train can be referred to in a number of different ways. Fox (1977) refers to dickens types of interval training, low force-out output interval training (LPO-IT) and senior laid-back king output interval training (HPO-IT). HPO-IT involves exercise and pause periods of less than one minute. Gibala and mcgee (2008) refer to steep warmth training (HIT). This broadly refers to repeated academic academic sessions of comparatively brief in destinationittent exercise often performed with an either out effort or at an bulk close to that which elicits VO2 boot (i.e 90% of vo2 poster). Depending on the training intensity, a single effort whitethorn last from a few seconds to up to several transactions with manifold efforts separated by up to a few min utes of quietus or low intensity exercise (Gibala and McGee, 2008). Minimum volume of HIT may be necessary to sum up VO2 flower and gain vigor early(a)(a) adaptations such as an increase capacity for fat oxidation. On the other hand Astrand and Rodahl (1977) say that exercise bouts lasting 3-5 minutes each are the longest recommended and are considered optimum for training aerobiotic processes. The purpose of high intensity training is to repeatedly stress the physiological systems that will be utilize during specific endurance type exercise (Daniels and Scardina 1984) to a greater extent than which is actually required during a specific activity. At any level of exercise, duration frequency, class length or initial fitness, intensity was the most important factor in producing improvements in aerobic power (Wenger and bell, 1986).Interval training in the highly trained athleteLandree (1997), lake and cavanagh (1996) and co motionlessness et al (1988) all track that an add itional increase in sub sludgeimal exercise doesnt appear to further improve endurance action and associated factors such as VO2 slime, anaerobic threshold, econonmy of motion and oxidative muscle enzymes. In highly trained individuals further improvements in performance can tho glide by via high intensity interval training (Landree 1997).Interval training in the sedentary and recreationally activeIt is generally believed that in sedentary (VO2 gook 60 ml/kg/min) (Rowell 1993, ekblom 1969). In contrast to this a sight by Hickson et al (1977) fix that the vo2 easy lay of eight sedentary and recreationally active people could be evidentiaryly increase after(prenominal)(prenominal) to 10 hebdomads of high intensity exercise training victimization cycling intervals.Lauresen and Jenkins (2002) as well as report transform endurance performance. They reported that high intensity interval training in sedentary and recreationally active individuals improves endurance performa nce more than continuous sub maximal training alone. This improvement appears delinquent to an up regulated contribution of both aerobic and anaerobic metabolism to the energy demand (Rodas et al 2000, MacDougall 1998). This could also be due to an improved capacity for aerobic metabolism through the increase in type 1 muscle fibres (Linossier et al 1993), cappiliristaion and oxidative enzyme activity.(Macdougall et al 1998, Essen et al 1977, chilibeck et al 1998). These adaptations are the most common due to High intensity interval training in untrainined or modertaley active.Holoszy and booth (1976) and Holoszy and Coyle (1984) report that submaximal endurance training has little or no effect on gylcolytic enzyme activity whereas supramaximal high intensity training can elicit up regulation of both glycolytic and oxidative enzyme capacity, maximal piffling term power but most importantly can increase VO2 max in an untrainined individual.Studies supporting increases in V02 max wi th interval trainingStudies permit translaten that 6-12 hebdomads of moderate intensity exercise can increase aerobic capacity and mitochondrial enzyme activity (gollnick et al 1973, hickson et al 1977) but sprint interval training at very high outputs (150-300% VO2 peak) for 6-7 work calendar calendar weeks also produces equal results (Macdougall et al 1998, Rodas et al 2000, Tabata et al 1996)Tabata et al (1996) carried out a theater involving 7-8 sets of 20 second high intensity exercise (170% of VO2 max) with 10 seconds rest between intervals. Post tests revealed a earthshaking increase in VO2 max of 7ml.kg.min. This study cerebrate that adequate high intensity sporadic training may improve both anaerobic and aerobic energy systems really through baronial intensive stimuli on both systems.Fox (1973) and (1977) comparabilityd low power output training compared to high power output training. It observed no engagements in Vo2 max gain with low power output training ver sus high power output training. This suggested that in long exercise repeats oxygen transport demands would be greater with vo2 max achieved in each exercise phase while in sprint repeats the high intensity may result in greater muscle hypoxia stimulating adaptations in muscle oxidative capacity.HIIT over a longer period of meter (4-6wk) has been reported to increase high-intensity exercise performance, muscle buffering capacity, whole consistence exercise fat oxidationrates, and aerobic capacity (Edge et al 2005, Laursen and Jenkins 2002, Weston et al 1997)Talanian et al (2007) found that after 2 weeks of high intensity aerobic intervak training vo2 peak increase by 13%.Rodas et al (2000) conducted a study to evaluate the changes in aerobic and anaerobic metabolism produced by a pertly devised on the spur of the moment training plan. The training involved quaternionteen training sessions everyday for two weeks. Training consisted of a number of 15 second all out sprints with 45 second rest and also a number of 30 second all out sprints with 12 minute rest periods. The come aparticipants involved were fairly active individuals. Results found an increase in vo2 peak pre and stock training from 57.3 +2.6 to 63.8 + 3.0 ml.min.kg quest a innovative exercise test.Macdougall et all 1998 conducted a study involving 30 second maximum sprint effort interspearsed by 2-4 minutes of recovery performed 3 fourth dimensions per week for 7 weeks. The program began with four intervals with four minutes recovery per session to 10 intervals with 2.5 minutes. The effect of the training program on VO2max was that it increased from 3.73 + 0.13 to 4.01 + 0.08l/min (P 0.05). Because in that respect were no squarechanges in torso mass over the training program, V O2max relative to body mass also increased significantly from 51.0 + 1.8 to 54.5 mlkg-1 min-1.Gorostiaga et al (1991) compared high intensity training, utilize repeated 30 second sprints with 30 second rest, to continous training at 50% of VO2 max. All participants rungd 30 minutes per day, 3 age a week for 8 weeks. Both ag sorts were exercising at the same miserly intensity. Post training additive tests revealed an increase in VO2 max, exercising work rate and peak power more so in the high intensity training separate (9-16% improvement) compared to the continous training theme ( 5-7% improvement).Studies by Edge et al (2005), Laursen and Jenkins (2002) and Weston et al (1997) have found that High intensity interval training for 4-6 weeks improved high intensity exercise performance, increased muscle buffering capacity, increased whole body fat oxidation rates and also improved aerobic capacity.Gibala and Mcgee (2008) reviewed the high intensity training interpellation the wingate test which involves 30 seconds of all out maximal cycling. This is also the method being use in this study. Protocols involved 4-6 wingates with 4 minutes of recovery between each one. A arrive of 2- 3 minutes of intense exercise per session with 3 sessions per week for 2-6 weeks( Burgomaster et al 2008,2007,2006 and Gibala et al 2006 ). There was no measurable change in VO2 peak after 2 weeks of interval training wingates as the preventative. This suggests that peripheral adaptations improved exercise capacity. On the other hand studies by ( Rodas 2000 and talanian et al 2007) found increases in vo2 max after just 2 weeks of high intensity training.Bailey et al (2009) also used the wingate based model for their training intervention. Particpants performed all out 30 seconds wingate with 4 in week one progressing to 6 and 7 in week 5 and 6. all(prenominal) wingate was separated by 4 minutes of rest. Post intervention examen showed a significant increase in VO2 max. Pre interrogatory participants had a vo2 max of 3.06+ 0.60 l/min which increased bet exam to 3.29+0.65 l/min. Also VO2 max increased in relative terms from 42+6 to 45+6 ml.kg.min. The other two other groups of p articipants one performing endurance training and the other a discover group showed no increase in V02 max.Studies not presentation improvement in VO2 max performanceFranch et al (1998) compared the effects of a continous training course of instruction and a high intensity training programme in recreational runners. All participants were split into leash groups. The first training group was a short high intensity training group which involved 30-40 15 second runs at 20.4km/h with 15 seconds rest between intervals. The second training group involved a long high intensity training programme which was 4-6 4 minute runs at 16.6km/h with 2 minutes of inactive rest. The last(a) group did a continous traning programme with 15km/h for 26 minutes. All groups trained troika times per week for six weeks . The results of this study found that continous and long high intensity interval training improved VO2 max than short high intensity training.Burgomaster et al (2006) and (2005) used a w ingate based training intervention for their study. 4-7 all out 30 second wingates were carried out over a 2 week period. Post scrutiny revealed no significant divagation in VO2 peak (pHypothesisFrom reviewing previous studies and studies victimisation similar methodology I excogitate that VO2 max will increase in post testing. I also hypothesise that peak electrical power in the incremental test will increase and also time to enervation. The priming for under taking this study is that I feel that other studies have looked at other factors earlier than specifically focusing on VO2 max.MethodSubjects16 healthy males from the University of Exeter Rugby Union Club volunteered to accede in this study ( symbolise age fishing and height and SD). The participants were contacted via email and also literally The playing fields regularly took part in exercise, usually involving 4 training sessions a week, two being skills based and the other two being resistance sessions. Particip ants were asked to carry one with normal training forwards any testing had began and were asked to uphold their normal diet throughout the duration of the study although participants were asked to refrain from alcohol 24 hours before any testing.Ethical procedureBefore any testing could be done the study had to be good approved by the University of Exeter School of sport and health sciences ethics board. Prior to the study all participants were inform fully about the study including all risks and all procedures involved verbally and in writing. All participants volunteered to be in the study and filled out informed consent forms in accordance with the ethics citizens committee of the University of Exeter. Particpants were informed they had the right to withdraw from the study at any point. All results gained from the study were kept unavowed and stored privately.Experimental designSubjects in the testing group were required to attend the laboratory on ten occasions over a 4 we ek period and project group on two occasions. All tests were separated with at least twenty four hours of recovery. All subjects undertook pre and post training incremental tests to ascertain Vo2 peak. Testing group then participated in a series of all out 30 second wingate tests over a four week training period.ScreeningParticipants were asked to fill out a PAR-Q (a physical activity readiness questionnaire) to make sure there were no underlying medical problems. A risk factor count was also undertaken which involved blood pressure measurement using a sphygmomanometer. Particpants were weighed (in kg) and height measured (in cm) and recorded. Weight being most important as this entropy was need to eastablish weight applied during the wingate tests.Incremental testsBoth before and after the training intervention all subjects performed ramp incremental tests to determine VO2 max. The ramp incremental tests were performed on an electronically braked cycle dynamometer (Lode Excalibu r Sport, Gronigen, The Netherlands). Subjects performed 3 minutes at 50 watts after which the wattage increased 1 watt every 2 seconds until volatile exhaustion. Subjects were asked to cycle at a constant rate of 80rpm. When the rpm dropped below 80rpm participants were back up to increase the rpm back up up and the test was ended when participants reached below 70rpm. Saddle and handlebar height was adjusted to suit each subject and then recorded for future reference in post testing. Verbal encouragement was used throughout to encourage participants to last as long as physically possible to obtain accurate data. gasconade exchange data was collected continuously using cortex gas analyser. VO2 max was taken from the highest range before the subjects volatile exhaustion. Heart rate was measured minute by minute using opposite heart rate monitor. After volatile exhaustion the end wattage and time at exhaustion was recorded.Training interventionAfter completing pre testing, the te sting group performed a series of all out 30 second sprints (Wingate tests) twice a week over a four week period. The Wingate tests were performed against a resistance equivalent to 0.075kg/kg body mass on a mechanically braked cycle ergometer (model 814E bicycle ergometer, Monark, Stockholm, Sweden). All wingates were interspersed with 4 minutes rest. In week one of testing participants were asked to perform 3 Wingates interspersed with four minutes of rest twice a week. This then increased by one Wingate per week (i.e week one ternary wingates, week two four wingates, week three five Wingates and week four six wingates).All participants were provided with a warm up on the cycle ergometer against no resistance. Having weighed the participants the pertinent weight was added to the basket. Five seconds before each Wingate participants were asked to generate high pedalling speed in order to progress to a rolling start for when the weight was dropped. Participants were told when the re was 10 and 5 seconds left of the test, so they could work at their maximal capacity for the duration of the test. During the rest periods participants were asked to cycle at a low meter against no resistance. The computer program wingate 30 provided data on peak power, mean power and sap rate. Verbal encouragement was given throughout the winagates to encourage maximal effort and water was provided during each rest interval.Statistical analysisAll pre and post incremental gas analysis was exported to Microsoft Excel. Standard statistical equations were carried out to calculate standard deviations and averages. The data was then input into SPSS (PC program, version 16 for windows) to calculate if the training intervention has a significant effect upon VO2 max. For the analysis a 2(testing v control) x 2 (pre v post) MANOVA ( three dependant variables, vo2 ml/kg/min, VO2 l/min and peak wattage) will be used. All data is represented in mean and standard deviation. The statistical significance level is set at PValidity and reliabilityValidity is described as whether the researcher truly measures that which it was intended to measure or how truthful the research results are. In a scientific experiment the aim is to manipulate a independant variable to produce an outcome on a dependant variable or variables. Once the researcher can confidently say that the changes in the dependant variable have been cause by the independant variable and no other factor the experiement is said to be internally valid (Levine et al 1994).This study is a valid and reliable study and several measures have been used to make sure of this Firstly a control, group was used. The creator being that it shows that it was the intervention that caused an increase in Vo2 max and peak wattage and no other outside factor and can provide a comparison. Another measure is that all participants were told not to transfer any current training regimes so this would not uphold pre or post test result s. right calibration of gas analyzer was carried out to make sure Vo2 max values were precise. Throughout the wingate tests verbal encouragement was used to ensure that participants were giving their maximum effort into the training to obtain the best results. This intervention has been carried out before and shows that it is a communications protocol which is reliable and valid.ResultsAll participants completed the 4 week training intervention. Each participant reported that they did not change their current training regimes outside of the intervention which may alter the results. The data was collected and then analysed. Results show that mean VO2 max in l/min, ml/kg/min and also peak wattage increased in the testing group after the intervention. Whereas the control groups data stayed similar due to no training intervention.Table 1.0 Mean VO2 MAX ML/KG/MIN, VO2 MAX L/MIN AND PEAK WATTAGE for Testing and control group.GROUPVO2 max ml/min/kgVo2 max l/minPeak wattageTestingPRE45.875 3.91383.5 gestate50.1254.315396.125Control8.5%9.4%3.2%PRE494.040395.5POST48.8754.050397.125Graph 1.0 Mean VO2 ml/kg/min pre and post training of testing and control groups.After the four week wingate training intervention, Vo2 max (ml/kg/min) in relative terms increased during the incremental vo2 max test. The mean residual in the testing group from pre to post tesing was 4.25 ml/kg/min, compared to the control groups mean difference of -0.125 ml/kg/min so the control groups mean relative Vo2 max decreased. Taking into account body weight this measure can be affected over time. One participant in the testing group started off with a weight of 118kg, at the end of the programme his weight dropped to 116kg, this caused the participant to have one of the biggest increases in relative VO2 max from 32 ml/kg/min to 41 ml/kg/min.Graph 1.1 Mean VO2 max l/min pre and post training for testing and control groups.Absolute Vo2 max (l/min) also increased in the testing group during the incremen tal Vo2 max test following the four week intervention. The mean difference pre and post testing in the training group was 0.405 l/min increase. Whereas the control group stayed the same with a 0.01 l/min increase.Graph 1.2 Peak wattage (w) pre and post training for testing and control groups.Mean peak wattage in the incremental Vo2 max test also increased following four weeks of wingate training in the testing group. This shows that participants who took part in the training programme could last longer during the post training Vo2 max test compared to the pre testing. This meant the time to exhaustion increased in the testing group. Mean peak wattage (w) increased from 383.5w to 396.125w showing a mean increase of 12.625w in the testing group. The control groups mean post peak wattage stayed similar with a mean increase of only 1.625w which was to be expectedThe data gathered from pre and post incremental test was input into the statistics programme SPSS to turn back if the increas ed found were statistically significant. The statistical test used was a 22 MANOVA. This test allowed me to compare groups (control and testing) and time (pre and post) to my three dependant variables (VO2 max ml/kg/min, l/min and peak wattage). imputable to the three dependant variables a multi analysis of variance (MANOVA) had to be used.Mutlivariate analysis using pillails trace showed no significant difference in group (testing and control) on the Vo2 max in ml/kg/min, l/min and peak wattage, V=0.145, F(3,26)=0.145, P0.05. Seperate Univariate ANOVAs were carried out on each variable and revealed no significant difference in group on VO2 max ml/kg/min F(1,28)=0.134, P0.05. No significant difference was found in group on VO2 max l/min F(1,28)=0.094, P0.05. Also no significant difference was found in group on peak wattage F(1,28)=0.364, P0.05. This shows there was no significant difference in testing and control groups in terms of the three variables.Multivariate analysis using pil lails trace showed no significant difference in time (pre and post) on the Vo2 max in ml/kg/min,l/min and peak wattage V=0.034, F(3,26)=0.306, P0.821. Seperate univariate ANOVAS revealed no significant difference in time on Vo2 ml/kg/min F(1,28)=0.646, P0.05, on Vo2 l/min F(1,28)=0.437, P0.05 and on peak wattage F(1,28)=0.903, P0.05. This shows there was no significant difference in pre and post results of the three variables.Multivariate analysis using pillais trace showed no significant difference in group (testing and control) x time(pre and post) on Vo2 max ml/kg/min, l/min and peak wattage V=0.037, F(3,26)=0.334, P0.05. Univariate ANOVAS revealed no significant difference of group x time on Vo2 max ml/kg/min, F(1,28)=0.727, P0.05. No significant difference was found for group x time on Vo2 max l/min, F(1,28)=0.822, P0.05. Also no significant difference was found for group x time on peak wattage F(1,28)=0.261, P0.05. This shows that testing group pre and post and control pre and post results were not statistically significant.Although these results did not show statistical significance, it cannot be ignored that they did show an increase. Despite that fact that the results were not significant all three variables increased following post testing. Results still show that the 4 week training programme was successful and the desired increases in Vo2 max (ml/kg/min, l/min) and peak wattage were achieved. Vo2 max in l/min saw the highest increase after the 4 week training intervention. Vo2 max l/min increased 9.4% in the testing group which is quite a considerable considering only 4 weeks of training was undertaken.DiscussionOver the 4 week training programme all sprints were carried out at a maximal intensity with participants verbally encouraged to do so. This led the testing to be very uncomfortable and severely demanding, despite this the when adding up total cycle time at maximal intensity , participants only cycled for 18 minutes over the four weeks. Desp ite the fact that the intervention did not prouduce statistically significant results it did show that the intervention worked and increase the three variables. . This shows that with only 18 minutes of intense cycling through wingate tests can increase Vo2 max in relative an absolute terms and peak wattage by 3-10% in an incremental vo2 max test. abbreviation of the evidence and relation to previous literatureThese results are similar to Bailey et al (2009) who used a similar intervention to the one use in this study. Bailey et al(2009) used one more wingate per session that this study (4 in week one increasing by one each week up to 7) and 4 minutes recovery time between each wingate. Results from this study showed a similar increase in Vo2 max, Bailey et al (2009) reported an increase in Vo2 peak of 8% which compared to the increase of 8.4% (ml/kg/min) and 9.5% (l/min) is very similar. This studys training programme may have had a slightly larger increases due to the 4 week progr amme compared to the 2 week training programme in Bailey et als (2009) study. Studies by Macdougall et al (1998)and Burgomaster et al (2008) also have reported increases of 7-8% in Vo2 max. Madougall et al (1998) also used the wingate based intervention but over a longer duration with a 7 week training programme and with 1 more session a week than the present study. Their results found a 7% increase in absolute Vo2 max and a 6.4% increase in relative Vo2 max. This is quite interesting considering the length and amount of sessions compared to the present study. The present study produced higher values in absolute and relative Vo2 max over four weeks. Macdougall et al (1998) also went up to 10 training intervals by the end of the study. This could potentially show that optimal time to obtain training adaptations could be around 4 weeks. Burgomaster et al (2006) also used a winagte protocol as its training intervention. Thier results are similar to what is found in this study. Vo2 max did increase after the 2 week training programme but after statistical analysis is was shown that this increase was not significant which is the same in the present study. Rodas et al (2000) also showed increases in Vo2 max after a short term interval training programme constsing of a mixture of 15 seconds and 30 second all out sprints which increase in number of the two week training programme. After the training programme maximal progressive test were carried out to obtain post test value of Vo2 max (ml.min.kg) and peak wattage, two of the variables being testing in this study. Results showed an increase of around 10% in Vo2 max (ml.kg.min) and a 9% increase in peak wattage in the maximal progressive test. This increase of the 2 weeks is similar to the data reported in this study. This increases the validity of the present study that two out of the three variables measured in this study are also reported in Rodas et al (2000) study.Gibala and Mcgee (2008) reviewed the wingate base d training intervention with studies of 4-6 wingates per session with 4 minute rest intervals which is similar to the present study. This review also concluded no changes in Vo2 max after the training intervention in studies by burgomaster 2005, 2006. One reason being wherefore no reported increase in Vo2 max was seen is due to the length of the training programme. Gibala and Mcgee actually report this in their review. They compare the work load of Burgomaster (2005) which they review and state that studies by rodas et al (2000) and talanian et al (2007) had a greater work load than Burgomaster (2005) which could be one reason for no change in Vo2 max. Iaia et al (2008) also showed no increase Vo2 max following a 4 week training intervention. As you can see there is mixed evidence towards the wingate based protocol as a training intervention to elicit improvements in VO2 max performance. Although some of these studies did not show increases in VO2 max, other performance based impro vements occurred. For example burgomaster et al (2005,2006) showed increases in time trial performance following four weeks of wingate based interval training.Despite some evidence to the contrary and statistical analysis showing the data in this study to not be significant, the fact that percentage increases in VO2 max are very similar to what has been reported in other studies. There can be many reasons to why high intensity interval training can increase VO2 max. The wingate test can be a very demanding test and is primarily used as a measurement of anaerobic capacity, showing peak power, average power and fatigue rates. Macdougall (1998) states that oxidative metabolism has a minor contribution to the energy delivered during each wingate test, although slievert at al (1995) says that the contribution of oxidative metabolism probably increased with every interval. The fact that using a wingate test with repeated intervals, participants can reach 140-210% Vo2 max during each inter val, this shows that training at intensities to a higher place Vo2 max can be more important than the volume of training and can stimulate increases in muscle oxidative potential (Macdougall et al 1998). Common responses to HIT in moderately active individuals is the carriage of type 1 fibres, capillirisation and oxidative enzyme activity (linossier et al 2003, Mcdougall et al 1998).The recovery phase of the wingate based training programme can have an important part to play in obtaining improvements in Vo2 max and other performance parameters. Passive recovery during the rest periods between each interval has been reviewed by billat (2001), because high levels of give suck develop during interval training performed at an intensity above the lactate threshold, active recovery facilitates this removal (hermansen and stensvold 1972). This removal allows althletes to tolerate heavy work rates for longer period of time ( Billat et al 2000). The rest days between each wingate session are also important. Rodas et al (2000) found significant increases in oxidative and glycolytic enzyme activity after two weeks of sprint training but this was no change in wingate performance after only one days rest. This improves the validity my results as partipants had more than one days rest between each wingate training session.Critical evaluation of the methodOne factor that could affect the amount of increase in Vo2 max could be baseline levels of Vo2 max. Participants with low baseline Vo2 are exhalation to see larger increases than participants who already have higher fitness levels. Although as I have mentioned before Landree (1997) states in highly trained individuals further improvements in performance can only occur via high intensity interval training. One major reason why the results of this study did not prove significant is the standard deviation. Participants with low baseline levels before the intervention may have showed an improvement in VO2 max and peak watt age but this improvement may still not have got them to the level of other participants baseline level. For example one participant increased their Vo2 max (ml.kg.min) from a baseline level of 39 ml.kg.min to a post intervention score of 50 ml.kg.min but this increase still did not pee-pee their Vo2 max level to the same as 4 other participants baseline. This variety in different peoples Vo2 max could be a reason why significant results were not obtained.A good comparison can be made between this study and Bailey et al (2009) due to similar participants being used. Their study used young adults with a mean age of 21 SD 4 which is a similar age to the participants in this study. One factor that could have been improved in this study is a larger sample s

History of Food

History of solid fodder ferocious feedHISTORYAbout 8000 BC gathering was the main basis of intellectual no(prenominal)rishment. en grand 10,000 BC, in the New Stone time, people started country, and then spent a sm each(prenominal)er amount of period gathering. Present they cultivated grain as a re typesetment for gathering it. People besides started to grow figs and lentils and parsnips and peas. solely they kept back on pick off many of other risky aliment for thoughts like berries, apples, pears, olives, and bonkers. They tucked snails from the bushes. By the Bronze Age ( one shot 3000 BC) people pose many other winsomes of food and collected less. People of Bronzed Age Cultivated grains and vegetables and also planted olive trees and fruit trees. Still, people pick berries, herbs, mushrooms, and nuts in the wild. Actually, the condition has non changed so a good deal from ult till now. Nowadays, so many people still collecting nuts and berries and they also st ill gather herbs and mushrooms.Its seem like collecting is a quite lazy, unsystematic kind of method to get foodstuff, and they dont want much information. But truly it is actually complex. They have to knowledge about where atomic number 18 the plants like where the berry bushes and nut trees argon developing. They have to know exploitation conductions of each of them will come ready (ripe), so that they dont miss to collect all the berries. They have to organize stuffs so that they are in the jell place at the correct time. Then also, they have to pick the berries they also have to preserve it and collect it in the store they have to bump the dry the berries and the grains and herbs and the fruits, and pickle the olives. Mainly people who grow the closely of their food from gathering and have a fixed way that they travel round every year, so that they will be at the right place at the right time period to get ripe nuts from the nut trees and at the olives when the olives bec ome ready to collect. wilderness STRAWBERRIES(Reference https//www.pinterest.com/pin/201395414563255124/ ) telescope Non-commercial wild food contains fish, insects, animals and plants that are harvested or hunted for own feeding. much(prenominal)(prenominal) collecting of wild food stuff is not matter to observant or risk organization in the way that commercially presented food. It is summary of non-commercial wild food stuff undertaken by NZFSA. NZFSA decided that wild food is risk free to the public health in New Zealand. But, the reexamine did expose a lack of information about harvesting and swallow uping patterns of wild food and also how to safely harvest food (plants) and train wild foodstuff, and also about the bacterias like the sources of foodborne illness. It is based on the soon available records. The three wild food groups with the maximum risk location are deer, shellfish and pigs. NZFSAs Strategy for Relating Mori in the Food safeguard and Consumer Protecti on Issues will support the application of the batty Food externalize for Mori peoples. NZFSA has established the educational resources for the Maori communities a Wild Food safety device DVD and two opposite booklets, Food safeguard for Seafood Gatherers and Food Safety for Hunters. NZFSA displays that the shellfish toxicity concluded the Marine Bio toxin Programmed, so that customers of non-commercial shellfish flock be advised when shellfish in their zone then it is vulnerable to have it and collect it. The other two foods (deer and pigs) that were recognized as possible high risk.(Reference http//waterlegacy.org/saving-wild-rice-sulfide-mining-pollution )CULTURE OF WILD FOODStill there were associations tries to spot wild gloss, there was not any accepted definition of it. smith chosen his colleagues and audiences to find the meaning of wild cultures throughout the titles of the tasks in which it looked, where the kind oscilloscope was at play that is, that it exist ed a serious-sounding and perchance honest schoolman magazine printed by a preserving culture with a lengthy name, all devoted to a topic no one recognized anything about. delegate the serious and the non-serious in a method that made logic and provoke became severalize of the artistes work. Previously there was Smiths fresh description of wild culture (the articulated ecotone between what people do and why they cant examine in nature), no single clarification happened around which the S.P.W.C artists effort was completed. most people said that it was the vagueness of the knowledge, the incapability to title it down that made it so eye-catching. In the lack of real explanation, Smith open a metaphor, which he has freshly changed On the surface of a clear painting is the kind physical reality that is portion of our ordinary life, and in the related are basics of nature, unseen and seen, that are very much active solely that people arent always alert of, whether out of apathy, convenience, ignorance, or any show of blackout or selfishness that donates to the interruption from our original history and our current psychic hold on the home land. Wild culture is the two planes, background and foreground, seen together.(Reference http//farmprogress.com/story-indian-country-bringing-revolution-wild-food-culture-9-120453 )INNOVATIONSSparkling soft drinks are also as a massive demand in Africa. To build additional growth on this market, WILD tastes and Specialty Ingredients resents novelties featuring new flavor profiles created on its original fermentation equipment. WILD tastes and Specialty Ingredients ideas for still drinks also give builders possible for additional growth. Food drinks technology in Africa, WILD tastes and Specialty Ingredients shows its competency in this part with product ideas counting emulsion-based decisions as well as milk and succus variations. These answers meet the demands of customers in Africa who want premium-quality drinks w hich have a flavorful taste. The most popular flavors here are tropical fruits like guava and mango. In adding, WILD Flavors and Specialty Ingredients displays non-alcoholic border drink ideas such as juice-based drinks with pia colada and sangria flavors.PRODUCTION METHODThe cultivated technique called Wild Farming. It is a growing different to factory farming. It consists of implanting crops that are extremely associated and kind to the natural ecosystem. It includes intercropping with inborn plants, resulting the contours and geography of the land, and backup to the local food chains. The oddment is to produce large crop yields, while still indorsing a wakeless environment. Wild farming is a reaction against the curtail of factory farming. Up till the mid-20th century, farming crop yields depend on natural inputs such as natural soil resources, rainfall patterns, built-in biological control mechanisms and recycling of organic matter. Presently, agricultural performs have been conventionalized to contain large mono cropped fields and use of synthetics fertilizers and pesticides. Avoiding the conventional farming practices, wild farming adopts many practices from sustainable agricultural systems such as Greywater systems, permaculture, forest farming, and agroecology. tender INFLUENCES OF WILD FOODCommunity effects have been shown to be very significant to overcome food neophobic in young boorren. But, there is no. experimental proof about whether social effects on food acceptance are item, that. is if models eating the same food as the child are more effective in sponsoring food acceptance than .eating a different food. We measured childrens behavior towards novel foods when an adult model A was not eating (Presence condition), B was eating a food of a Different strain (Different colouring material condition), and C was eating a food of the same color (Same color condition). We tested 26 children (ages 2-5 years old) enrolled from The Pennsylvania Sta te University day mete out amenities. Grades show that kids accepted and ate their novel food additionally in the same color form rather than different color and in the Presence conditions. Hence, in young children food acceptance is promoted by specific social influences. These data show that children are more love to eat new food if others are eating the same type of food than others are merely present or eating another kind of food.

Human Activities Global Warming And Climate Change Environmental Sciences Essay

homoity Activities Global Warming And humor Change Environmental Sciences EssayClimate switch is a long-term substitute in the Earths humour, or of country on the Earth (Nasa.gov, 1975). Humans custom energy in their workaday life much(prenominal) as driving cars from one base to other place. However, close to of their activities effect the environment. gibe to Nap.edu (1996), it states that world(prenominal) stability is threated by the human activities. This is because human activities emit amounts of nose candy dioxide.Furthermore, Newscientiest.com (2007) besides states that based on IPCC handle (2001), 90% of the causes of modality change are from the human activities. Besides that, Nasa.gov (1975) to a fault states planetary warming is the changes in the Earths average surface temperature due to go aims of babys room gases. Human activities such as deforestation, capable importunate and waiver of greenhouse gases through transit have become the larg est contributors to world(prenominal) warming. So, in that location is a relationship between the human activities, global warming and temper change. This is because human activities emit excess century dioxides that lead to cytosine defilement and gum olibanum cause global warming and temper change. Nrdc.org (2012) states that the coke taint is the chief(prenominal) cause of the Earth are getting warmer, increase the relative frequency of drought, and flood. Since the average temperature increases rapidly, human and other living things provide face the consequences such as the melting of glacier, acid rain and the rising of ocean level too. Hence, human activities such as deforestation, emission of greenhouse gases from transportation and vindicated burning are the main causes of the global warming and thusly climate change.In monetary value of deforestation, Climateandweather.net (2010) states that deforestation is causing the necessary function of trees to be lessen ed and affect the climate. It besides states that forests store coke dioxide, kick upstairs oxygen, supremacy the climate, and purify our water supply and air. So, that means forests are vital for our life. However, there are reasons that cause deforestation to happen such as illegal enter operation and agriculture.Wwf.panda.org (2011) mentions that the logging activity keeps happen in violation of interior(a) laws.Most of the illegal loggings happen because of the ascending demand for papers and timbers. Therefore, the operation keeps inveterate without permission from the government. Besides that, illegal loggings also include activities such as harvesting wood from restricted areas and exporting exotic species of trees. In terms of agriculture, Wwf.panda.org (2011) states that illegal logging can also occur when the forests are vindicated for a plantation such as oil palm or rubber plant. Even the plants also absorb the nose candy copy dioxide as uniform as the forest , the plant involve more times to grow up and able to absorb more cytosine dioxide desire forest do.Climateandweather.net (2010) mentions that most of agricultural crop and other smaller plants also draw in carbon and release amounts of oxygen, but the forests able to store up to degree centigrade times more carbon dioxide than other plants. So, it emphasized that the forests are very(prenominal) important to stabilize the global warming. Besides that, water is also require to skip the excess carbon dioxide in the air. Since the forest is a place where the water is purified, the water can also help to reduce the carbon dioxide. The rainforest and ocean play a big role in this aspect. According to Worldwatch.org (2012), it states the oceans are by far the largest carbon dioxide sink in the Earth. However, since deforestation keeps happening, even the sea becomes limited to sink all the carbon dioxides. Loss amounts of trees increase the amounts of carbon dioxides at the atmosp here lead to global warming and thus climate change.Moreover, another factor of climate change is the emission of greenhouse gases from the vehicles on the road. Transportation produce energy from the burning of fossil fuels and change into motion. Only this way can makes them enable to feign from one place to another place. Greenhouse gases such as carbon dioxide are the most emitted gas from on-road vehicles. Epa.gov (2010) mentions transportation that use fossil fuels is the main ancestry of carbon dioxide emission. There are numerous transportation sources for lesson air travel, marine transportation and highway vehicles. Most of the vehicles use gas pedal and diesel in crop to transport good or people. G.Roger (2012) states profuse vehicles physical exertion causes the transportation emission increases and leads to global warming. This is because uncontrollable greenhouse gases from the transportation depart lead other heat- boundping gases and carbon dioxide gas to th e atmosphere. So, there will be more and more excesses carbon dioxide will be produce and emit to the atmosphere. This matter will lead global warming and thus climate change since the global average temperature keeps increasing. Furthermore, based on Broadus (2012) states those greenhouse gases emissions are leading to sea level rises and thus floods in variant places. Streams, rivers and reservoirs are not able to support and store excesses water since the sea level increase rapidly. Even the dams unable to stop the flowing water to entered the protected places. These enigmas lead floods to occur in various places especially in the cities and villages nearby the beach or rivers. Besides that, monsoon rains in certain places like Mumbai will be another problem to this matter. Broadus (2012) also mentions about heavier monsoon rains will make the floods worse. Thus, excesses transportation emission will lead to the dangerous change on climate change such as increasing the sea leve l and affect the monsoon circulation.Another catalyst of global warming and climate change is blunt burning in various places. It is an activity that produces rattling large amounts of carbon dioxide which change the Earths temperature and cause the melting of glaciers due to the global warming. This is because open burning release heat from the flame that enhances the warming in the atmosphere. The open burning not only releases carbon dioxide, but also ominous carbon which is the second global warming agents after carbon dioxide. According to Kanittha and Savitri (2012) mentions in their research that warming effect from colour carbon will be increase as it mixed with other particles in the air such as carbon dioxide. They also mention black carbon enable to enhance the melting of snow or glacier deuce-ace times that of carbon dioxide. As the carbon dioxide also emitted together with black carbon, the affect must be fatal and more dangerous on global warming and climate chan ge. Human activity such as open burning of agricultural residues after harvesting is the main source that leads black carbon and carbon dioxide emission to the atmosphere. Kanittha and Savitri (2012) also state the combustion of the crop waste is the significant source that release black carbon and other greenhouse gases. So, the production of carbon dioxide and black carbon trap tremendous amount of heat and raise the Earths temperature causing severe extend to on the Arctic. As the global getting warmer, the melting of glaciers continues to occur in high speed which is also leads to increase the sea level. This unstoppable problem worries the whole nations in the world as they lost habitats and their life is in danger as the land become limited and covered by the water. Other living things such as animals and trees also are cladding the same problems as they lost their habitats and most of exotic species become extinct. Therefore, open burning also has negative impacts to both o f the environment and people.The climate is a major part of the Earths environmental system and cannot be replaced by human. According to the Intergovernmental Panel on Climate Change (2007) states there are m either ways to mitigate the global warming and climate change. However, the main see of the solution is the cooperation and unity from the people so they enable to make a different in order to reduce the carbon pollution and global average temperature. One of the solutions is to follow the regulation provided by the government such as prevent the illegal logging operations or deforestation. This mode enables the trees using up the carbon dioxide from the atmosphere. The water is also able to use the carbon dioxide with sinking the carbon dioxide. Since it becomes limited, people need to reduce carbon dioxide more. Besides that, carpooling and limit the transportation usages on the road are also helps to reduce the amount of carbon dioxide in the atmosphere. This is because t he small amount of vehicles usage will lessen the emission of greenhouse gases especially carbon dioxide. sight also can develop and use other alternative or renewable energy to replace fossil fuel such as solar energy. Tom (2012) mentions transportation that powered by solar electricity emit about less or zero percent of carbon dioxide is the most efficient way to reduce large amounts carbon dioxide. However, around-the-clock researches and new environment-friendly technology need to conduct by human in order more alternatives can be used. Moreover, people also need to decrease their open burning activities. They can try recycling any reusable material or things in order to prevent the open burning. So, there are more and more carbon dioxide will be cut off. Hence, people need to try any ways to reduce deforestation, carbon dioxide emission from transportation and open burning in order to decrease global average temperature or global warming and climate change. Otherwise, the gl obal warming will continue to affect the climate change, and thus people, animals, and environment will have the difficult time to face the consequences.
