The Proof Dilemma of Porter’s Hypothesis:Analysis of Its Verification Difficulties

The Porter Hypothesis,proposed by Michael E.Porter,suggests that stringent environmental regulations can enhance corporate innovation and competitiveness,challenging the traditional view that regulations increase business costs.It argues that regulations motivate firms to innovate,leading to improved productivity,cost reductions,and new market opportunities.However,there are proponents and critics in academia regarding the hypothesis.Supporters claim regulations change corporate behavior,reducing agency costs and boosting research and development.Critics argue that if win-win situations exist,businesses would naturally pursue them without regulatory incentives.Key challenges in proving or refuting the hypothesis include its various versions,the difficulty in quantifying innovation and competitiveness,the complex interplay between regulation,innovation,and competitiveness,and the varying impacts across industries and regions.Additionally,the effects may require a long time to manifest,and the hypothesis’s applicability is influenced by evolving environmental policies and market environments.Despite mixed empirical findings,the Porter Hypothesis provides a valuable framework for understanding the relationships among environmental regulation,innovation,and competitiveness,but its validation requires a more comprehensive assessment.

Alzheimer’s disease risk after COVID-19:a view from the perspective of the infectious hypothesis of neurodegeneration

In light of the rising evidence of the association between viral and bacterial infections and neurodegeneration,we aimed at revisiting the infectious hypothesis of Alzheimer’s disease and analyzing the possible implications of COVID-19 neurological sequelae in long-term neurodegeneration.We wondered how SARS-CoV-2 could be related to the amyloid-βcascade and how it could lead to the pathological hallmarks of the disease.We also predict a paradigm change in clinical medicine,which now has a great opportunity to conduct prospective surveillance of cognitive sequelae and progression to dementia in people who suffered severe infections together with other risk factors for Alzheimer’s disease.

Comparison of Vs and SPT Soil Liquefaction Assessments of NCEER: Including Hypothesis Testing

Soil liquefaction is one of the complex research topics in geotechnical engineering and engineering geology. Especially after the 1964 Niigata earthquake (Japan) induced many soil liquefaction incidents, a variety of soil liquefaction studies were conducted and reported, including the liquefaction potential assessment methods utilizing the shear wave velocity (Vs) or SPT-N profiles (SPT: standard penetration test). This study used the Vs and SPT methods recommended by the National Center for Earthquake Engineering Research (NCEER) to examine which is more conservative according to the assessment results on 41 liquefiable soil layers at sites in two major cities in Taiwan. Statistical hypothesis testing was used to make the analysis more quantitative and objective. Based on three sets of hypothesis tests, it shows that the hypothesis—the SPT method is more conservative than the Vs method—was not rejected on a 5% level of significance.

Intense Mid-Infrared Laser Pulse Generated via Flying-Mirror Red-Shifting in Near-Critical-Density Plasmas

Relativistic femtosecond mid-infrared pulses can be generated efficiently by laser interaction with near-criticaldensity plasmas.It is found theoretically and numerically that the radiation pressure of a circularly polarized laser pulse first compresses the plasma electrons to form a dense flying mirror with a relativistic high speed.The pulse reflected by the mirror is red-shifted to the mid-infrared range.Full three-dimensional simulations demonstrate that the central wavelength of the mid-infrared pulse is tunable from 3µm to 14µm,and the laser energy conversion efficiency can reach as high as 13%.With a 0.5–10 PW incident laser pulse,the generated mid-infrared pulse reaches a peak power of 10–180 TW,which is interesting for various applications in ultrafast and high-field sciences.

Fuzzy Proportional Integral Derivative control of a voice coil actuator system for adaptive deformable mirrors

Research on adaptive deformable mirror technology for voice coil actuators(VCAs)is an important trend in the development of large ground-based telescopes.A voice coil adaptive deformable mirror contains a large number of actuators,and there are problems with structural coupling and large temperature increases in their internal coils.Additionally,parameters of the traditional proportional integral derivative(PID)control cannot be adjusted in real-time to adapt to system changes.These problems can be addressed by introducing fuzzy control methods.A table lookup method is adopted to replace real-time calculations of the regular fuzzy controller during the control process,and a prototype platform has been established to verify the effectiveness and robustness of this process.Experimental tests compare the control performance of traditional and fuzzy proportional integral derivative(Fuzzy-PID)controllers,showing that,in system step response tests,the fuzzy control system reduces rise time by 20.25%,decreases overshoot by 78.24%,and shortens settling time by 67.59%.In disturbance rejection experiments,fuzzy control achieves a 46.09%reduction in the maximum deviation,indicating stronger robustness.The Fuzzy-PID controller,based on table lookup,outperforms the standard controller significantly,showing excellent potential for enhancing the dynamic performance and disturbance rejection capability of the voice coil motor actuator system.

Neural Correlates of Developmental Coordination Disorder: The Mirror Neuron System Hypothesis

Primary impairments of developmental coordination disorder (DCD) include impairments in motor skill, motor learning, and imitation. Such difficulties present challenges for individuals with DCD and may persist into adulthood, negatively impacting daily life in school, work, and social domains. A better understanding of the neural correlates of motor and imitation impairments in DCD holds the potential for informing development of treatment approaches to address these impairments. Although the disorder is assumed to be of neurological origin, little is known of the brain-based etiology of DCD. In recent years the discovery of a fronto-parietal circuit—known as the mirror neuron system—has enabled researchers to better understand imitation, general motor functions, and aspects of social cognition. Given its involvement in imitation and other motor functions, we propose that dysfunction in the mirror neuron system may underlie the characteristic impairments of DCD. We review literature pertaining to the mirror neuron system and develop a theory of disordered mirror neuron functioning in DCD. Finally, we review the limited neuroimaging literature available on neural correlates of DCD and show that the findings from those investigations are congruent with a mirror neuron system theory of DCD. Future research in this population should be designed to investigate specifically mirror neuron regions in individuals with DCD during skilled motor tasks and imitation in particular.

Sapir-Whorf Hypothesis and Translation

Sapir-Whorf hypothesis has its implication in translation studies. Each language is a peculiar whole. It is a product, even an expression, of the spiritual personality and the cultural particularity. Translation is a kind of interlingual and intercultural communication. It involves not only the transference from one language into another, but a whole set of extra-linguistic criteria. In translating we are always crossing a greater or lesser barrier or divide.

Multi-Angle Exploration on the Inner Relationship among Language,Thought and Culture with “Sapir-Whorf Hypothesis”

“Sapir-Whorf hypothesis"holds that human thoughts are shaped by their native languages,and speakers of different languages think differently relevantly.The hypothesis is controversial partly because it seems to deny the possibility of a general principle for human cognition,and partly because some findings taken to support it have not reliably replicated.The author argued that considering this hypothesis through the lens of probabilistic inference has the potential to figure out both issues,at least with respect to certain prominent findings in the two languages—Chinese and English.After exploring on the inner relationship among language,thought and culture with the comparison between English and Chinese based on a series of examples including“numbers,Wuhan dialect and some different understandings of idioms”,the author made an inference that language can somewhat affect human thought under the different culture contexts.Besides,it also provides some reference for educators to take in-depth studies on the relationship among language,thought and culture,which is vitally significant for ESL educators and learners.

分析族群冲突问题的新模式——试评Ethnic Conflict:Commerce,Culture,and Contact Hypothesis

加拿大多伦多大学政治学系福布斯(H.D.Forbes)教授的著作《族群冲突:贸易、文化及接触理论》在分析、借鉴其它社会科学研究成果的基础上,向人们展示了一种理解和诠释族群冲突问题的新视角。该著作通过评析"接触理论"的利弊,提出了一个替代性的"语言模型"。以"语言模型"为基础的研究表明接触怎样能够同时改善和恶化族群关系:在个人层面上,接触能使族群关系更加和谐;但在群体层面上,接触可能会激发人们保留各自的群体认同,从而避免他们在同化中付出沉重代价。福布斯认为,接触是一个过程,而不是一个结果,它能打破社会分层,减少文化差异,但同化威胁到一个群体的存在,因此增加了彼此间的紧张关系。毋庸置疑,族群间的差异是冲突合理存在且不可避免的重要原因。

Pharmacokinetics of traditional Chinese syndrome and recipe:a hypothesis and its verification(Ⅰ)

AIM To propose a hypothesis defining theabsorption,distribution,metabolism andelimination of traditional Chinese recipe（TCR）-component in blood of healthy subjects andpatients,and estimate its correctness.METHODS The pharmacokinetics（PK）of samedose of drug was studied in the animal model oftraditional Chinese syndrome（S）and healthyanimals.The classification,terminology,concept and significance of the hypothesis wereset forth with evidence provided in the presentstudy.The hypotheses consisted of traditionalChinese syndrome PK（S-PK）and traditionalChinese recipe PK（R-PK）.Firstly,the observedtetramethylpyrazine（TMP）PK in healthy,chronically reserpinized rats（rat model ofspleen deficiency syndrome,RMSDS）andRMSDS treated with Sijunzi decoction（SJZD）forconfirmation were used to verify S-PK; secondly,the ferulic acid（FA）PK in healthy andhigh molecular weight dextran（HMWD）-inducedrabbit model with blood stasis syndrome（RDBSS）was also used to verify S-PK;andlastly,TMP PK parameters in serum of healthyrats after orally taken Ligusticum wallichii（LW）,LW and Salvia miltiorrhiza（LW&SM）decoctions were compared to verify R-PK.RESULTS The apparent first-order absorption[Ka,（13.61±2.56）h-1,area under the blooddrug concentration-time curve[AUC,（24.88±9.76）μg.h-1mL-1],maximum drug concentration[Cmax,（4.82±1.23）μg·mL-1]of serum TMP inRMSDS were increased markedly（P【0.05）compared with those[Ka=（5.41±1.91）h-1,AUC=（5.20±2.57）μg·h-1·mL-1,Cmax=（2.33±1.77）μg·mL-1]of healthy rats（HR）.Theapparent first-order rate constant for α and βdistribution phase[α=（0.38±0.09）h-1,β=（0.06±0.03）h-1,the apparent first-orderintercompartmental transfer rate constants[K10=（0.24±0.07）h-1,K12=（0.11±0.02）h-1,K21=（0.11±0.02）h-1]of serum TMP in RMSDS weredecreased significantly（P【0.01）comparedwith those[K10=（0.88±0.20）h-1,K12=（1.45±0.47）h-1,K21=（0.72±0.22）h-1]of HR.However,no apparent differences occurredbetween HR and RMSDS treated with SJZD.Theserum FA concentration and its AUC[（5.6690±2.3541）μg·h-1·mL-1] in RMBSS were also higherthan those[AUC=（2.7566±0.8232）μg·h-1·mL-1]of healthy rabbits（P【0.05）.The Ka（11.51±2.82）h-1,AUC（0.84±0.17）μg·h-1·mL-1of LW & SM-derived TMP in serum weremuch lower（P【0.05）than those[Ka=（19.58±4.14）h-1,AUC=（1.27±0.26）μg·h-1·mL-1]ofLW-derived TMP in serum after oral decoctions.CONCLUSION The SDS and blood stasissyndrome state could affect significantly thepharmacokinetic parameters of drugs and theabnormal SDS pharmacokinetic parameters couldbe normalized by SJZD.The combination ofChinese medicine in TCR could reciprocallyaffect the pharmacokinetic parameters of othercomponents absorbed into the systemiccirculation.These results support the S-and R-PK hypothesis.

从Sapir-whorf Hypothesis到文化强势论——汉英对比看文化的制约性

Sapir-Whorf的语言决定论假说曾在很长一段时间居于学术界主导地位。但笔者却以为此理论存在一些不足之处,如夸大了语言的功能,解释力有限,忽略了语言的历时变化,以及无法解释语言变异等。而从语言与文化的关系来看,作者更倾向于文化影响语言,即语言差异源于文化差异。
