To date, however, there has still been no explicit guideline or method. By applying emissions allowance allocated by 16 schemes as benchmarks, this paper tries to compare and evaluate the NDCs of the top six emitters, which jointly account for about 70% of the world's CO_2 emissions. Results show that the four developed countries' NDCs lack ambition with respect to most allocations under 2℃ and all under 1.5℃, indicating they need to substantially ratchet up their NDCs and lead elevating mitigation. Evaluating cumulative emissions is more likely to clarify the ambition and fairness of China's NDC. If considering cumulative emissions, China's NDC is aligned with the median of cumulative allowances under 2℃ and within the 1.5℃ range. The Paris Agreement invited the Parties to communicate the mid-century low emissions strategies. This paper also tries to explore the mid-century mitigation in the perspective of allocations, which might provide decision-makers with some useful information when envisaging the post-NDC mitigation.展开更多

However, ...Various soft materials share some common features, such as significant entropic effect, large fluctuations, sensitivity to thermodynamic conditions, and mesoscopic characteristic spatial and temporal scales. However, no quantitative defini- tions have yet been provided for soft matter, and the intrinsic mechanisms leading to their common features are unclear. In this work, from the viewpoint of statistical mechanics, we show that soft matter works in the vicinity of a specific thermo- dynamic state named moderate point, at which entropy and enthalpy contributions among substates along a certain order parameter are well balanced or have a minimal difference. Around the moderate point, the order parameter fluctuation, the associated response function, and the spatial correlation length maximize, which explains the large fluctuation, the sensitivity to thermodynamic conditions, and mesoscopic spatial and temporal scales of soft matter, respectively. Possible applications to switching chemical bonds or allosteric biomachines determining their best working temperatures are also briefly discussed.展开更多

Workplace violence (WPV) has a spectrum of forms. In more extreme forms it generally is low frequency but has high impact when it occurs. Healthcare systems’ efforts to reduce Burnout are more likely to remain sustained since the impact is experienced daily and awareness is increasingly publicized. The efforts to reduce WPV are harder to sustain due to the lower frequency combined with daily competing administrative demands despite best intentions. Could efforts to reduce the overlapping organizational contributions to both HCW Burnout and WPV be a strategy to sustain prevention of WPV while preventing Burnout? A model of overlapping organizational contributions to HCW Burnout and WPV is built from supporting literature. Recommendations are made for leadership and management style interventions. Potential benefits would be higher quality and satisfaction in patient care by means of higher satisfaction in the delivery of care, recruitment and retention of excellent staff, retention of high quality institutional knowledge and reputation.展开更多

However<i>,</i> low case detection and unsuccessful treatment outcome still remains a serious challenge in most states. Community Tuberculosis care was born against this background in 2010 as a complementing front to combat the challenges<i>,</i> bringing directly observed treatment short-course strategy beyond the clinic settings to the door steps of patients. This study evaluates the contributions of the intervention to Tuberculosis case detection and treatment outcomes in two states in Nigeria. <b>Materials and Method:</b> A retrospective study with multistage sampling technique was employed to review 23<i>,</i>241 presumptive Tuberculosis cases enrolled for management between 2014-2017. Chi-square (<i>χ</i><sup>2</sup>) test was used for test of association between the independent variables and the main outcomes of the study<i>,</i> with statistical significance set at p-value of 5%. <b>Results</b>: The annual percentage increase for both states was 24.7%<i>,</i> 189.8% and 114.5% in the study group as against 5.2%<i>,</i> 44.6% and 65.6% in control group.

Of the total 5861 cases treated<i>,</i> successful treatment rate of the patients in the study group was 88.6% as compared to 76.1% in the control group. The relationship between the referral system from communities where the intervention program was implemented and the case detection/treatment outcome was statistically significant (OR 95% CI = 3.15<i>,</i> 2.95 - 3.35). <b>Conclusion</b>: The community level Tuberculosis intervention led to significantly better case detection and treatment outcome when compared to the conventional approach (p ≤ 0.05).

Our model pre-supposes that the inflationary potential pioneered by Guth is equivalent in magnitude in its initial inflationary state to the effective potential presented in the Randall-Sundrum model. We also consider an axion contribution to chaotic inflation (which may have a temperature dependence) which partly fades out up to the point of chaotic inflation being matched to a Randall-Sundrum effective potential. If we reject an explicit axion mass drop off to infinitesimal values at high temperatures, we may use the Bogomolnyi inequality to re-scale and reset initial conditions for the chaotic inflationary potential. One of the potential systems embedded in the Randall-Sundrum brane world is a model with a phase transition bridge from a tilted washboard potential to the chaotic inflationary model pioneered by Guth which is congruent with the slow roll criteria. If, as written up earlier, the axion wall contribution is due to di-quarks, which is equivalent to tying in baryogenesis to the formation of chaotic inflation initial conditions, with the Ran-dall-Sundrum brane world effective potential delineating the end of the dominant role of di-quarks, and the beginning of inflation.展开更多

The carbon emissions accounting method of the Intergovernmental Panel on Climate Change was used to calculate the actual CO2 and the support vector machine model was used to predict CO2. Chinese carbon reduction policies abated CO2 in the six carbon trading pilot schemes after the comprehensive policies came into force. However, the contribution of policies to CO2 abatement varied among regions, and the effect of carbon reduction policy on municipality pilot schemes was greater than on provincial pilot schemes. The largest contribution of carbon reduction policy to CO2 abatement was 28.3%, for the pilot carbon trading scheme in Beijing, and the smallest contribution was 3.7%, for that in Hubei. It is crucial to consider "carbon leakage" and a carbon trading linking program in order to evaluate the effects of carbon reduction policies.展开更多

Around the moderate point, the order parameter fluctuation, the associated response function, and the spatial correlation length maximize, which explains the large fluctuation, the sensitivity to thermodynamic conditions, and mesoscopic spatial and temporal scales of soft matter, respectively. Possible applications to switching chemical bonds or allosteric biomachines determining their best working temperatures are also briefly discussed.
文摘The effects of Burnout in healthcare workers (HCW) are experienced by the worker, other staff, the institution and patients under their care on a daily basis. Workplace violence (WPV) has a spectrum of forms. In more extreme forms it generally is low frequency but has high impact when it occurs. Healthcare systems’ efforts to reduce Burnout are more likely to remain sustained since the impact is experienced daily and awareness is increasingly publicized. The efforts to reduce WPV are harder to sustain due to the lower frequency combined with daily competing administrative demands despite best intentions. Could efforts to reduce the overlapping organizational contributions to both HCW Burnout and WPV be a strategy to sustain prevention of WPV while preventing Burnout? A model of overlapping organizational contributions to HCW Burnout and WPV is built from supporting literature. Recommendations are made for leadership and management style interventions. Potential benefits would be higher quality and satisfaction in patient care by means of higher satisfaction in the delivery of care, recruitment and retention of excellent staff, retention of high quality institutional knowledge and reputation.
文摘<b>Background: </b>Nigeria<i>,</i> one of the high burden Tuberculosis countries<i>,</i> has developed various intervention strategies to ensuring universal access to quality-assured tuberculosis diagnosis and treatment. However<i>,</i> low case detection and unsuccessful treatment outcome still remains a serious challenge in most states. Community Tuberculosis care was born against this background in 2010 as a complementing front to combat the challenges<i>,</i> bringing directly observed treatment short-course strategy beyond the clinic settings to the door steps of patients. This study evaluates the contributions of the intervention to Tuberculosis case detection and treatment outcomes in two states in Nigeria. <b>Materials and Method:</b> A retrospective study with multistage sampling technique was employed to review 23<i>,</i>241 presumptive Tuberculosis cases enrolled for management between 2014-2017. Chi-square (<i>χ</i><sup>2</sup>) test was used for test of association between the independent variables and the main outcomes of the study<i>,</i> with statistical significance set at p-value of 5%. <b>Results</b>: The annual percentage increase for both states was 24.7%<i>,</i> 189.8% and 114.5% in the study group as against 5.2%<i>,</i> 44.6% and 65.6% in control group. Overall<i>,</i> 23.8% were bacteriologically positive (either AFB or Gene-Xpert MTB/Rif) and 1.4% were clinically evaluated to be positive<i>,</i> while 74.8% were bacteriologically negative. Of the total 5861 cases treated<i>,</i> successful treatment rate of the patients in the study group was 88.6% as compared to 76.1% in the control group. The relationship between the referral system from communities where the intervention program was implemented and the case detection/treatment outcome was statistically significant (OR 95% CI = 3.15<i>,</i> 2.95 - 3.35). <b>Conclusion</b>: The community level Tuberculosis intervention led to significantly better case detection and treatment outcome when compared to the conventional approach (p ≤ 0.05). Therefore<i>,</i> full community engagement should be advocated as a major strategy for End Tuberculosis planed by WHO since the patients are found in the community and not in the health facilities.
文摘Trends in the proportional contribution to the seasonal rainfall of each month were analyzed for the meteorological stations of Buffalo Range, Masvingo Airport and Zaka in South-Eastern Zimbabwe. Results found indicate the existence of some trends for all the stations and months. However, when subjected to a Mann-Kendel trend analysis, all the trends were found to be statistically not significant for all instances except for the month of October at the Zaka station. This month showed a significant trend of increasing proportional rainfall.
文摘We examine from first principles the implications of the 5th Randall Sundrum Brane world dimension in terms of setting initial conditions for chaotic inflationary physics. Our model pre-supposes that the inflationary potential pioneered by Guth is equivalent in magnitude in its initial inflationary state to the effective potential presented in the Randall-Sundrum model. We also consider an axion contribution to chaotic inflation (which may have a temperature dependence) which partly fades out up to the point of chaotic inflation being matched to a Randall-Sundrum effective potential. If we reject an explicit axion mass drop off to infinitesimal values at high temperatures, we may use the Bogomolnyi inequality to re-scale and reset initial conditions for the chaotic inflationary potential. One of the potential systems embedded in the Randall-Sundrum brane world is a model with a phase transition bridge from a tilted washboard potential to the chaotic inflationary model pioneered by Guth which is congruent with the slow roll criteria. If, as written up earlier, the axion wall contribution is due to di-quarks, which is equivalent to tying in baryogenesis to the formation of chaotic inflation initial conditions, with the Ran-dall-Sundrum brane world effective potential delineating the end of the dominant role of di-quarks, and the beginning of inflation.
文摘Over the past 70 years since the founding of the People’s Republic of China,great changes have been seen in the financial industry in terms of its nature,function,scale,structure and other features.It has experienced six stages of development,namely,inception and consolidation,arduous growth,exploration and restructuring,segmentation,fictitious economy orientation,and real economy promotion and risk prevention.The tremendous success and useful experience made during this period have largely bolstered the prosperity and stability of the Chinese economy,improved Chinese people’s living standards,and exerted a profound impact on China’s economy and society.Based on its development pattern,the Chinese financial sector will expect further openingup at home and abroad and a growing capacity in serving the real economy,while new business forms and models will emerge rapidly and stronger preventive measures against financial risks will be needed.In response to the financial development in the new era,proactive and pragmatic measures need to be in place to safeguard the stable and sound development of the financial industry.

文摘The contributions of carbon reduction policies were evaluated and compared for six carbon trading pilot schemes in China, in four municipalities(Beijing, Shanghai, Tianjin, and Chongqing) and two provinces(Guangdong and Hubei). The carbon emissions accounting method of the Intergovernmental Panel on Climate Change was used to calculate the actual CO2 and the support vector machine model was used to predict CO2. Chinese carbon reduction policies abated CO2 in the six carbon trading pilot schemes after the comprehensive policies came into force. However, the contribution of policies to CO2 abatement varied among regions, and the effect of carbon reduction policy on municipality pilot schemes was greater than on provincial pilot schemes. The largest contribution of carbon reduction policy to CO2 abatement was 28.3%, for the pilot carbon trading scheme in Beijing, and the smallest contribution was 3.7%, for that in Hubei. It is crucial to consider "carbon leakage" and a carbon trading linking program in order to evaluate the effects of carbon reduction policies.
文摘The salaries of the chief executive officers of the DAX-30 enterprises are often in the spotlight of the public and the general discussion.By contrast,the pension contributions for the members of the management boards of the DAX-30 enterprises are mostly below the radar,although they have become increasingly more significant during the past years.In spite of the given transparency by the German Corporate Governance Code(the“code”)and its obliging conversion into the management remuneration disclosure law(VorstOG),the pension contributions have not moved in the spotlights of the public and their attention.The illustration of the extent of the pension contributions for DAX-30 enterprises shows the quintessential point of this investigation.Additionally,their administrative forms are discussed,implied moral hazard problems are illuminated,and malus regulations for pension contributions are examined.The result of the investigation will contain recommendations for supervisory boards and the government commission of the German Corporate Governance Code as well as ideas for further research.
