We analyse the relationship between the extent of a firm’s corporate social responsibility (CSR) and its long-term survival probability. We conjecture that a better CSR rating is associated with a lower probability of corporate failure and a longer survival period. Consistent with this, we document that four CSR dimensions (environment, community, employee relations, and product) out of six are positively related to firms’ survival probability. The positive association between CSR ratings and firm survival is stronger for firms operating in more competitive industries and those with weaker governance. We find that a firm’s engagement in CSR activities is particularly crucial for firm survival during pandemics and under adverse climate conditions. We establish causality in the relation between a firm’s CSR activities and its survival probability using instrumental variable (IV) and Heckman two-step analyses. Finally, we find that better financial performance, less stringent financial constraints, greater managerial discipline, and enhanced labor productivity are some of the channels through which firms engaging in more CSR activity achieve longer survival times.
本文分析了企业社会责任程度与其长期生存概率之间的关系。我们推测,企业社会责任评级越高,企业破产的概率越低,生存期越长。与此一致的是,我们证明了企业社会责任的六个维度中的四个维度(环境、社区、员工关系和产品)与企业的生存概率呈正相关。企业社会责任评级与企业生存之间的正相关关系在竞争更激烈的行业和治理较弱的行业中更为明显。我们发现,企业参与企业社会责任活动对企业在大流行和恶劣气候条件下的生存尤为重要。我们利用工具变量(IV)和Heckman两步分析建立了企业社会责任活动与其生存概率之间的因果关系。最后,我们发现更好的财务绩效、更宽松的财务约束、更严格的管理纪律和更高的劳动生产率是参与更多企业社会责任活动的企业获得更长的生存时间的一些渠道。

There are various methods to solve the physical life problem involving engineering, scientific and biological systems. It is found that numerical methods are approximate solutions. In this way, randomly generated finite difference grids achieve an approximation with fewer iterations. The idea of randomly generated grids in cartesian coordinates and polar form are compared with the exact, iterative method, uniform grids, and approximate solutions in a generalized expansion form of two-dimensional fractional-order Legendre functions. The most ideal and benchmarking method is the finite difference method over randomly generated grids on Cartesian coordinates, polar coordinates used for numerical solutions. This concept motivates the investigation of the effects of the randomly generated meshes. The two-dimensional equation is solved over randomly generated meshes to test randomly generated grids and the implementation. The feasibility of the numerical solution is analyzed by comparing simulation profiles.
解决物理生命问题的方法多种多样,涉及工程、科学和生物系统。发现数值方法是近似解。通过这种方式,随机生成的有限差分网格以更少的迭代实现近似。将笛卡尔坐标和极坐标下随机生成网格的思想与二维分数阶勒让德函数的精确、迭代法、均匀网格和广义展开形式下的近似解进行了比较。最理想的和基准的方法是有限差分法在随机生成的网格上笛卡尔坐标,极坐标用于数值解。这个概念激发了对随机生成网格效果的研究。在随机生成的网格上求解二维方程,以测试随机生成的网格及其实现。通过对仿真剖面的比较,分析了数值解的可行性。

Indoor rock climbing is a relatively new sport; as a result, many legal issues as applied to the sport have not yet been explored. Because indoor rock climbing is rapidly increasing in popularity, issues like the copyright of indoor rock climbing routes will become relevant to the industry’s legal landscape. The growth of modern indoor rock climbing gyms has put a spotlight on route-setting. Today, it is clear that one of the main ways an indoor rock climbing gym becomes and remains successful is through innovative and sensitive route-setting that provides customers with new and challenging climbing experiences. Route-setting has become its own art form; the route-setter is the artist, the holds are the paint, the blank slab of wall is the canvas, and the climbing customer is the individual experiencing the route-setter's creation. Despite the fact that indoor rock climbing routes are works of sculptural art, there is no legal scholarship exploring potential copyright protection of these works. As useful articles, indoor rock climbing routes would have to survive a separability analysis to achieve protection for its fixed, artistic elements. However, indoor rock climbing routes currently pass separability analysis under the new standard established by the Supreme Court in Star Athletica, L.L.C. v. Varsity Brands, Inc (“Star Athletica”), allowing the routes themselves to be eligible for copyright protection. This comment presents a framework for analyzing the ability to copyright indoor rock climbing routes in light of recent developments established by Star Athletica and subsequent cases. Indoor rock climbing routes are eligible for copyright protection as artistic sculptural works. Section II discusses the history of indoor rock climbing and the development of the modern route-setting profession. Section III advances the framework that proves that indoor rock climbing routes are copyright-able, first by discussing the issue of issue articles and separability, then by examining the new test for separability as set forth in Star Athletica and its progeny. Section IV discusses the details associated with copyright protection for indoor rock climbing routes, comparing and contrasting literal movement with physical aesthetic similarity. Finally, Section V discusses the future of the indoor rock climbing industry, how copyright will co-exist with the development of the sport, and concludes.
室内攀岩是一项相对较新的运动;因此,许多适用于这项运动的法律问题尚未得到探讨。由于室内攀岩正在迅速普及,室内攀岩路线的版权等问题将成为该行业法律格局的相关问题。现代室内攀岩馆的兴起使路线设置成为人们关注的焦点。今天,很明显,室内攀岩馆取得并保持成功的主要途径之一是通过创新和敏感的路线设置,为客户提供新的和具有挑战性的攀岩体验。路线设置已经成为一种独特的艺术形式;路线设定者是艺术家,手是颜料,墙体的空白板是画布,攀岩客户是体验路线设定者创作的个体。尽管室内攀岩路线属于雕塑艺术作品,但目前尚无法律研究探讨这些作品的潜在版权保护问题。作为有用的文章,室内攀岩路线必须通过可分离性分析,以保护其固定的艺术元素。然而,根据最高法院在Star Athletica, L.L.C.诉Varsity Brands, Inc(“Star Athletica”)一案中建立的新标准,室内攀岩路线目前通过了可分离性分析,允许路线本身有资格获得版权保护。这篇评论提出了一个框架,可以根据Star Athletica最近的发展和随后的案例来分析室内攀岩路线的版权保护能力。室内攀岩路线作为艺术雕塑作品享有版权保护。第二部分讨论了室内攀岩的历史和现代路线设置职业的发展。第三部分提出了证明室内攀岩路线具有版权性的框架,首先讨论了发行文章和可分性的问题,然后考察了《Star Athletica》及其衍生文章中提出的可分性的新检验。第四部分讨论了室内攀岩路线版权保护的相关细节,比较和对比了文字运动与物理美学相似性。最后,第五部分讨论了室内攀岩产业的未来,版权将如何与这项运动的发展共存,并进行了总结。

The paper compares the multi-dimensional energy-momentum equation with the relativistic energy-momentum equation. We show that the relativistic energy-momentum equation is wrong and unable to explain the mass-energy equivalence in the multi-dimensional real space. Bertozzi’s experiment is good evidence for showing the problem of the relativistic energy- momentum equation. Multi-dimensional energy-equation can explain the total energy of the particles in the Bertozzi’s experiment and explain the relationship between the mass-energy formula of the particles in the n-dimensional spacetime.
本文将多维能量动量方程与相对论能量动量方程进行了比较。我们证明了相对论能量-动量方程是错误的,不能解释多维实空间中的质能等价。贝托齐的实验是证明相对论能量-动量方程问题的良好证据。多维能量方程可以解释Bertozzi实验中粒子的总能量,也可以解释n维时空中粒子的质能公式之间的关系。

This paper reports the established feature of non-linear differential equations as those that most adequately describe the properties of objects. Possible methods of their linearization have been analyzed. The issues related to solving the original equations in a linearized form have been defined. The Riccati equation has been given as an example.For a special type Riccati equation, a method to solve it has been constructed, whereby the results are represented in an analytical form. It is based on the use of linearization and a special method of nondimensionalization.A special feature of the constructed method is determined by its application not to the original equation but to its discrete analog. The result of solving it is an analytical expression based on elementary functions. It is derived from using the existing analytical solution (supporting, basic) to one of the equations of the examined type. All the original equations of the examined type have the same type of solution. This also applies to equations that had no previous analytical solution.A formalized procedure for implementing the devised method has been developed. It makes it possible to link the analytical type of solution to the examined equation and known analytical solution to the basic one. The link is possible due to the equality of discrete analogs of the considered and basic equations. The equality of discrete analogs is provided by using a special nondimensionalization method.The applicability of the method and the adequacy of the results obtained have been shown by comparing them with existing analytical solutions to two special type Riccati equations. In one case, the solution has movable special points. In the second case, a known solution has an asymptote but, at the positive values of the argument, has no special points.The possibility of using the constructed method to solve the general Riccati equation has been indicated.
本文报告了非线性微分方程的既定特征,即那些最充分地描述物体性质的特征。分析了它们线性化的可能方法。用线性化形式求解原方程所涉及的问题已经得到了定义。给出了里卡第方程的例子。对于一类特殊类型的里卡蒂方程,构造了一种求解方法,其结果用解析形式表示。它是基于使用线性化和一种特殊的无量纲化方法。所构造方法的一个特殊之处在于它不是应用于原始方程,而是应用于它的离散模拟。求解的结果是一个基于初等函数的解析表达式。它是利用现有的解析解(支持的、基本的)得到的。所检验的所有原始方程都具有相同类型的解。这也适用于之前没有解析解的方程。已制定了实施所设计方法的形式化程序。它使得将解析解与检验方程联系起来,将已知解析解与基本解联系起来成为可能。由于所考虑的方程和基本方程的离散类似物相等,这种联系是可能的。利用一种特殊的非量纲化方法,给出了离散类似物的等价性。通过与已有的两种特殊类型Riccati方程解析解的比较,证明了该方法的适用性和所得结果的充分性。在一种情况下,解具有可移动的特殊点。在第二种情况下,已知解具有渐近线,但在参数的正值处没有特殊点。指出了用所构造的方法求解一般Riccati方程的可能性。

Every year a large number of individuals have to quit different military services: army, navy, air force etc. for different reasons all over the world. Among all the reasons, medical discharge is the most unacceptable one. After forced departure from the service, these personnel face several problems as they go through a difficult and sensitive time in their life. Starting from post-traumatic stress disorder (PTSD), they go through different mental, psychological, social and psychopathological problems. Further, people look at them in a different way when they come to know that the person had to resign from military services. Moreover, the behavior and attitude of the family members and relatives make the situation worse. Ex-military personnel of this category suffer from depression. However, the person can be turned into a positive and effective power of the society by proper support from the surroundings as the person can use the learning from his/her experience in other occupations as well. The paper draws attention towards this social problem. The benefits of the research will have an impact on the ex-military community of forced departure, as this problem has not been addressed properly in broader context before.
每年,世界各地都有大量的人由于不同的原因不得不退出不同的军种:陆军、海军、空军等。在所有的原因中,医疗出院是最不能接受的原因。在被迫离开军队后,这些人在经历人生中困难和敏感的时期时面临着一些问题。从创伤后应激障碍(PTSD)开始,他们经历了不同的精神、心理、社会和精神病理问题。此外,当人们知道这个人必须从军队中辞职时,人们会以不同的方式看待他们。此外,家庭成员和亲戚的行为和态度使情况变得更糟。这类退伍军人患有抑郁症。然而,通过环境的适当支持,这个人可以变成一个积极有效的社会力量,因为这个人也可以从他/她的经验中学习到其他职业。这篇文章引起了人们对这个社会问题的注意。这项研究的好处将对被迫离开的前军人群体产生影响,因为这个问题以前没有在更广泛的背景下得到妥善解决。

Injunctions and Hold-up under Weak Patent Protection 专利保护不力下的禁令和拖延
Pub Date : 2020-05-01 DOI: 10.23895/KDIJEP.2020.42.2.1

This paper analyzes how injunctions relate to patent hold-up problems. To this end, we present a simple model of licensing negotiations between a patent holder and a downstream firm in the shadow of litigation. More specifically, we consider the situation in which an injunction is granted as a matter of course if a patent is found valid and infringed upon in litigation, but the patent holder may be under-compensated due to aspects of the patent remedy system other than injunctions. We show that if the downstream user is unaware of the patent before any investment in initially designing its product, the patent hold-up problems created by injunction threats are worrisome when (i) the redesign process is costly, (ii) the degree of patent protection (by aspects of the patent remedy system other than injunctions) is sufficiently strong and (iii) the injunction is requested not to practice the patented technology exclusively but to collect excessive patent royalties. Even if the downstream user is aware of the patent before the initial investment, the patent hold-up problems do not disappear. The findings here imply that a discretionary approach is required towards denying injunctions against patent infringement. If the degree of patent protection is not sufficiently strong, denying injunctions can exacerbate the under-compensation problem. However, once patent protection improves enough (not necessarily perfectly), we may see a surge of patent hold-up problems, and it would be better to apply alternative patent remedies in place of injunctions when necessary. Lastly, we discuss several possible alternatives to injunctions and their pros and cons.
本文分析了禁令与专利拖延问题的关系。为此,我们提出了一个专利持有人和下游公司在诉讼阴影下进行许可谈判的简单模型。更具体地说,我们考虑的情况是,如果一项专利在诉讼中被认定有效并受到侵犯,那么禁令被理所当然地授予,但由于专利救济制度的其他方面,专利持有人可能会受到禁令以外的补偿不足。我们表明,如果下游用户在对其产品进行初步设计之前不知道专利,那么当(i)重新设计过程成本高昂,(ii)专利保护程度(通过除禁令以外的专利救济制度方面)足够强,以及(iii)要求禁令不专门实践专利技术,而是收取过多的专利版税时,禁令威胁造成的专利持有问题令人担忧。即使下游用户在初始投资之前知道专利,专利持有问题也不会消失。这里的研究结果表明,在驳回针对专利侵权的禁令时,需要酌情处理。如果专利保护的程度不够强,驳回禁令会加剧赔偿不足的问题。然而,一旦专利保护得到足够的改善(不一定是完美的),我们可能会看到专利拖延问题激增,在必要的时候,最好采用替代专利补救措施来代替禁令。最后,我们讨论了禁令的几种可能的替代方案及其优缺点。

Lastly, we discuss several possible alternatives to injunctions and their pros and cons.","PeriodicalId":220342,"journal":{"name":"Materials Science Educator: Courses","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122073208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metacognition is knowledge and awareness about the process of cognition or learning about the mind and how it works. Solving mathematical problems requires the involvement of metacognition. This study aims to obtain the results of identification of students' level of metacognition in problem-solving and the level of metacognition of students in mathematical literacy on social arithmetic material. This research was conducted at SMP Negeri 3 Palimanan. This type of research is qualitative research. The subjects of this study were students of class VII C Middle School 3 Palimanan. Data collected by test and interview methods. Data were analyzed using data reduction, data presentation, and concluding. The results of this study indicate that the level of metacognition of students in solving mathematical problems and mathematical literacy has mixed results. In solving mathematical problems, students who have high learning outcomes are at the level of Reflective Use metacognition, students who have learning outcomes are at the Strategic Use metacognition level, and students who have low learning outcomes are at the Tacit Use metacognition level. Meanwhile, the level of student metacognition in mathematics literacy is not much different from solving mathematical problems. Students who have high learning outcomes are at the Reflective Use metacognition level, students who have learning outcomes are at the Strategic Use metacognition level, and students who have low learning outcomes are at the Aware Use metacognition level. Overall the level of metacognition of students both in solving mathematical problems and in mathematics literacy is at the level of Strategic Use metacognition
元认知是关于认知过程的知识和意识,或关于心灵及其工作方式的学习。解决数学问题需要元认知的参与。本研究旨在获得学生解决问题的元认知水平和学生对社会算术材料的数学素养的元认知水平的识别结果。本研究在SMP Negeri 3 Palimanan进行。这种类型的研究是定性研究。本研究以巴利马南C中学七班学生为研究对象。通过测试和访谈方法收集数据。数据分析采用数据简化、数据呈现和结论。本研究结果表明,学生数学解题元认知水平和数学素养水平存在着好坏参半的结果。在解决数学问题时,学习成果高的学生处于反思使用元认知水平,学习成果好的学生处于策略使用元认知水平,学习成果低的学生处于默会使用元认知水平。同时,学生的数学素养元认知水平与数学解题水平差异不大。学习成果高的学生处于反思使用元认知水平,学习成果好的学生处于策略使用元认知水平,学习成果低的学生处于意识使用元认知水平。总体而言,学生在数学解题和数学素养方面的元认知水平都处于策略使用的元认知水平
