美国物流学论文代写：旅游、环境与可持续发展

随着全球化和国际一体化的到来，旅游和旅游运动不断扩大。这种过度扩张是由于社会经济和技术的发展造成的，但是这种大规模旅游所造成的是对环境的破坏。可以说，航空旅行的需求一直在急剧增长，然而，航空部门无论如何都不能被认为是可持续的。这是因为飞机本身消耗自然资源，能够满足可持续发展的原则(Gossling, 2012)。随着人们渴望在更短的时间内迅速解决从一个地方到另一个地方的旅行问题，航空公司一直在令人担忧地扩大服务，造成环境恶化。据信，飞机引擎会释放噪音、有害气体和微粒，这些都会导致气候变化和全球变暖。二氧化碳的排放是造成环境破坏的最重要因素。尽管涡轮风扇、涡轮螺旋桨发动机、机身、空气动力学、飞行作业等技术都在减排，但二氧化碳排放并没有减少或减少，主要原因是多年来航空旅行需求的激增。飞机不仅排放二氧化碳，还向大气中排放碳氢化合物、一氧化碳、黑碳、硫氧化物、氮氧化物、铅等，造成了严重的环境污染(Johnston, 2013)。航空部门的业务对环境造成了退化，这显然意味着没有遵守可持续发展的原则。可持续发展的重要组成部分之一是环境保护，它支持执行反污染法律和其他污染控制措施。像维珍航空这样的航空公司对环境造成了空气污染，这证明航空公司没有遵循可持续发展的原则。可持续发展的另一个重要原则是环境与经济决策的整合，即航空公司等企业必须通过对环境、人类健康和社会影响的反思来做出经济和盈利决策(Kaur Sahota, 2016)。旅游业特别是航空旅游业与环境之间存在着强烈的冲突，不符合可持续发展的要求。这意味着社会福利、经济和环境没有得到有效的管理，无法平等地向现在和后代提供利益。

美国物流学论文代写：旅游、环境与可持续发展

With the advent of globalization and international integration, tourism and tourism movement have been expanding. This over-expansion has been caused due to the socioeconomic and technical development but what this mass tourism is causing is devastating for the environment. It can be said that the demand for air travel has been growing abysmally, however, the airline sector cannot be considered to be sustainable in any possible way. This is because aircraft themselves consumes natural resources and could meet the principles of sustainable development (Gössling, 2012). With people desiring for quick solutions to travel from one place to another in less possible time, airlines have been alarmingly expanding their services and creating environmental degradation. The aircraft engines are believed to emit noise, harmful gases and particulates that are responsible for causing climate changes and global warming. It is the carbon dioxide emission that forms the most significant element of the aviation’s contribution to the environmental damage. In spite of the emission reductions technologies like turbofan and turboprop engines, airframes, aerodynamics and flight operations, there is no decrease or reduction in the CO2 emissions mainly due to the upsurge in the air travel demand over the years. Aircraft not only emits carbon dioxide but also emits hydrocarbons, carbon monoxide, black carbon, sulfur oxides, nitrogen oxides, lead etc. into the atmosphere causing substantial environmental pollution (Johnston, 2013). The operations of the airline sector have been causing degradation to the environment which evidently implies that the principles of sustainable development are not adhered to. One of the significant parts of the sustainable development is environmental protection which supports the enforcement of anti-pollution laws and other pollution control measures. The fact that airlines like Virgin Atlantic have been causing air pollution in the environment proves that the airline companies do not comply with the principles of sustainable development. Another important principle of sustainable development is the integration of environmental and economic decisions which state that companies like airline companies must make economic and profitable decisions by reflecting on the effects on the environment, human health and social impacts (Kaur Sahota, 2016). The tourism especially air tourism does not comply with sustainable development as there is a strong conflict between tourism and environment. This implies that social well-being, economy and environment are not effectively managed to impart benefits equally to the present as well as the future generations.

美国护理学代写论文：知情同意

关于知情同意的概念，出现了许多心理问题。与知情同意相关的问题或挑战之一是语言障碍。由于语言翻译方法的不恰当，有时会造成个人观点的误解。这种情况在治疗过程中增加了研究者或医生的责任。个体的宗教方面可以作为参与治疗或研究过程的障碍，因为通过个体宗教设定的行为规则可能会影响接受治疗(Bowman et al.， 2011)。此外,错误预期的心理问题也可以知情同意作为治疗的病人可能担心他或她可能被视为一个实验模型研究或研究,或病人可以拒绝,因为历史事实的不端行为或欺诈行为由特定的诊所。有时，由于患者对试验费用的感知，或者由于提供了大量关于试验风险或副作用的信息，患者害怕开始试验，因此很难获得知情同意，患者也可以拒绝。因担心医疗费用超出保险范围，患者可拒绝治疗或拒绝同意。这些心理问题可以作为获得患者知情同意的障碍。

There are number of psychological problems which arise with regards to the concept of informed consent. One of the issues or challenges related with informed consent is the language barrier. As sometime, misunderstanding individual’s viewpoint can occur due to the inappropriate method of language translations. This situation raises the responsibility of the researcher or the doctor when the treatment process is going on. Religious aspects of the individuals can act as barrier for participating in the treatment or research process as the behaviour rule set through the individual’s religion may influence to accept the medical treatment ( Bowman et al., 2011). In addition to this, false expectations can also be a psychological problem with the informed consent as the patient may fear of treatment as he or she may be treated as an experimental model for a research or study, or patient can refuse because of the historical facts of the misconducts or frauds done by that particular clinic. Sometimes, receiving informed consent becomes difficult due to the patient’s perception about expense on trials, or the vast information given on the risk of the trials or the side-effects can make the patients fear to start the trail and he or she can refuse. Patients can refuse for the treatment or deny to give consent as they have fear concerning to the medical expenses that may not be covered by their insurance. These psychological problems can act as barrier in obtaining informed consent from the patients.

美国音乐学论文代写：人脸识别技术

人脸识别或人脸表示技术作为一种非接触生物识别技术，在各种情况下都得到了广泛的应用。传统的人脸识别方法不能满足当前市场的需求(Kasar et al.， 2016)。这是因为传统的方法精度很低，甚至在各种场合都受到限制。不受限制的人脸识别需要大量的努力和技术。然而，目前的人脸识别技术已经取得了较高的准确率和较低的入侵率。人脸识别产生了“无干扰的生理方法”的准确性(Kasar et al, 2016, p. 83)。这也是人脸识别引起心理学、安全、犯罪研究、图像处理和计算机视觉等领域研究人员关注的原因。人脸识别是在各种算法中产生的，在多媒体图像处理中被证明是非常重要的。

人脸识别技术分析了不同人脸图像的各种特征。这些图像是通过创意相机的输入和在线图像捕捉产生的。然而，人脸识别技术的现状是不成熟的，它是随着深度学习的发展而进步的(Sun et al.， 2015)。人脸识别技术也被引入以验证人的真实身份。这项技术是专门基于生物识别领域的。Kasar et al.(2016)认为，“生物识别技术是一种利用独特的生理特征(如指纹、眼睛、脸等)或行为特征(如声音和签名等)来识别人的技术”(82页)。简单来说，可以说生物识别是利用计算机进行人脸识别。生物识别系统主要包括人脸检测、预处理、特征提取和人脸识别四个部分。

Face recognition or the face representation is significantly used in various circumstances as the non contact biometrics. The conventional method of face recognition could not justify the current demands of the market (Kasar et al., 2016). This is because the conventional method produced very low accuracy and it was even restricted at various occasions. The unrestricted face recognition requires significant efforts and techniques. However, the current technology in face recognition is successful in producing high accuracy and low intrusiveness. Face recognition has produced the accuracy of the “physiological approach without being intrusive” (Kasar et al, 2016, p. 83). This has been the reason that face recognition has drawn the attention of the researchers from the field of psychology, security, criminal studies, image processing and computer vision. Face recognition is produced in various algorithms and has proved to be very important in the multimedia image processing.

The technique of face recognition analyses various characteristics of the image of different faces. These images are produced through the input of the idea cameras and through online image capturing. However, the state of the art technology of the face recognition is done and it has advanced by the development of the deep learning (Sun et al., 2015). Face recognition technology has also been introduced for the verification of the actual identity of the person. This technology is specifically based on the field of Biometrics. According to Kasar et al. (2016), “Biometrics is a technique for identifying people by using a unique physiological characteristic, such as a fingerprint, eye, face, etc. or behavioural characteristics, e.g., voice and signature etc” (p. 82). In simple words, it can be said that Biometrics is the use of computer for face recognition. There are four main elements of the biometric system that includes Face Detection, Pre-processing, Feature Extraction and Face Recognition.

论文代写：写论文的标准有哪些?不管做什么事都是有要求有标准的，论文也是一样，是有特定标准的，在格式、选题、论据、中心论点等都有明确的规定和要求。那么，写论文的标准有哪些?下面我们就一起来看看吧。

论文代写：写论文的标准有哪些?

1、论点明确。读者在阅读完文章标题后，在文献综述中或是阅读过程中明确你的文章论点。鉴于读者也是具备相当的水平的，所以如果你的文章论点是比较新颖的(绝大多数学生总是喜欢论证已有的观点)，读者能够阅读到新的东西，自然是很好的。

2、中心突出。一篇论文要有一个核心论点，不管分几个部分几个分论点来论证，都要围绕着核心进行。

3、论据充分。写作者很早的一些素材，可能是参考文献，可能是自己亲身调查实践得出的数据等，都要贴切论题，而且要尽可能多。

4、结构完整且合理。结构和思路最能反映留学生的思维。在分段的时候要注意层次，分段不要过多或过少。

5、表述清楚明晰。使用的英文最好是很地道的，在用词、词组和句式的时候避免犯低级错误，语言干净利落，最好是整篇文章能有一定的文风和语体。

6、排版规范。这是稍微后面的步骤了，因为主要内容已经完成了，后期的排版可以参考学校给出的标准进行，或者请人作指导，问题不大。

7、修改。对写好的文章一定要仔细检查，从内容到结构，从语言到排版。

8、写作态度。从开始准备到开题报告和大纲，从写作过程到修改过程都要用自己全部的力量去完成，尽可能找一切的材料，高度重视，思考一切相关的问题。
