Chapter 8 explores how Huawei was able to emerge as the leader in the telecommunications system sector, overtaking the incumbent Swedish giant Ericsson. It answers this question by focusing on whether a latecomer firm trying to catch up uses technologies similar to or different from those of the forerunners. The study investigated patents by Huawei and Ericsson and found that Huawei relied on Ericsson as a knowledge source in its early days but subsequently reduced this reliance and increased its self-citation ratio to become more independent. The results of mutual citations, common citations, and self-citations provided strong evidence that Huawei caught up with or overtook Ericsson by taking a different technological trajectory. Huawei developed its technologies by relying on more recent and scientific knowledge; in terms of citations to scientific articles and citation lags, Huawei extensively explored basic research and up-to-date technologies to accomplish its technological catch-up. This study suggests that leapfrogging by exploring a new technological path is a possible and viable catch-up strategy for a latecomer. Moreover, Huawei’s case re-confirms the hypothesis that catch-up in technological capabilities tends to precede that in market share. Huawei overtook Ericsson in terms of quantity and quality of patents before annual sales. In summary, the results suggest that Huawei’s catch-up with Ericsson in the telecommunications equipment market is owing not only to its cost advantage, the large domestic market, or the Chinese government’s support but also more importantly to its technological leapfrogging based on its technological strength and independence.

Abstract Background The United Nations Convention on the Rights of Persons with Disabilities [1] highlights the need to create proper socioeconomic and political conditions for persons with disabilities, with a special focus on their immediate living conditions. According to the Convention, these conditions should be built to ensure that persons with disabilities have the potential to enjoy a high quality of life (QoL), and this principle is reflected in the notion of livable areas. The crucial aspect of this framework is the relationship between the individual QoL and the environment, broadly understood as the socioeconomic as well as the technical conditions in which persons with disabilities function. Methods The basic research problem was to assess the relationship between individual QoL for the population with disabilities as a dependent variable and livability indicators as independent variables, controlling for individual characteristics. The study used a dataset from the EU-SILC (European Union Statistics on Income and Living Conditions) survey carried out in 2015 in Poland. The research concept involved several steps. First, we created a variable measuring the QoL for the entire population with disabilities. To measure the multidimensional QoL, we used Sen’s capability approach as a general concept, which was operationalized by the MIMIC (multiple indicators multiple causes) model. In the second step, we identified the livability indicators available in the official statistics, and merged them with survey data. Finally, in the last step, we ran the regression analysis. We also checked the data for the nested structure. Results We confirmed that the general environmental conditions, focused on creating livable areas, played a significant role in shaping the QoL of persons with disabilities; i.e., we found that the higher the level of the local Human Development Index, the higher the quality of life of the individuals living in this area. This relationship held even after controlling for the demographic characteristics of the respondents. Moreover, we found that in addition to the general environmental conditions, the conditions created especially for persons with disabilities (i.e., services for this group and support for their living conditions) affected the QoL of these individuals. Conclusions The results illustrate the need to strengthen policies aimed at promoting the QoL of persons with disabilities by creating access to community assets and services that can contribute to improving the life chances of this population.

Creative participation refers to citizens’ invention of, and engagement in, new action forms that aim to influence, or take responsibility for, the common good in society. By definition, these action forms are constantly evolving and cannot be listed or summarized. Yet some, like guerrilla gardening, have over time become more established in political repertoires, and specific arenas are known to be particularly productive sites for their development. These include in particular the Internet, and lifestyles and consumption. The constant changes in how citizens become active represented by creative participation present considerable challenges for scholars of political participation—both in terms of theory and methodology. In particular, such forms test our ability to distinguish political from nonpolitical activities. However, how political creative participation is, is often subtle and implicit, and therefore hard to establish. Yet being able to do so is essential for an ongoing assessment of the quality of participatory democracy. With conventional forms of participation declining and creative participation becoming more common, scholars must be able to agree on definitions and operationalizations that allow for the comparison of participatory trends. For instance, a key concern has been whether creative forms of participation crowd out more conventional ones, like voting or lobbying politicians. Developments in survey research have been able to show that this is not the case and that creative participation may in fact increase conventional participation. In addition, qualitative research methods like focus groups and ethnography, allow for more open-ended explorations of this elusive research topic. As to who participates, creative participation has enabled traditionally underrepresented groups like women and young people to catch up with, and sometimes overtake, those older men who have long dominated conventional political participation. Still, education remains a key obstacle even to creative participation. The COVID-19 crisis that took hold of the world in 2020 has compromised access to collective action and public space. It has thereby once more put the onus on citizens to engage creatively with ways to influence, and take responsibility for, society. At the same time, the crisis presents a need and opportunity for political participation scholarship to engage more deeply with theoretical debates about what it means to be political or to participate.

Although significantly develops in hepatocellular carcinoma (HCC), features of HCC remain an aggressive cancer with a dismal outcome. Traditional Chinese medicine (TCM), specifically Chinese herbal medicine (CHM), is one of the most popular complementary and alternative medicine modalities worldwide. The use of heat-clearing and detoxicating (Chinese namedqingre jiedu) CHM has attracted great attention as an alternative antitumor including HCC considering its low toxicity and high activity. Together these reports indicate that CHM is a promising anti-HCC herbal remedy in basic research. For patients with advanced HCC, CHM including formula and single combined with transcatheter arterial chemoembolization or chemotherapy is able to decrease tumor growth and the side effect of toxicity and improve overall survival, quality of life, and immune function. Due to its abundance, low cost, and safety in consumption, CHM remains a species with tremendous potential for further investigation in HCC.

During 39th session of UNESCO General Conference which held on 7 November 2017 the date May 16th was proclaimed as International Day of Light (IDL). This decision was made after the success of the International Year of Light (IYL) celebrated in 2015. It confirmed that raising awareness of the social role of photonics is crucial for further development. Based on the rich experience of IYL 2015 ("more than 13,000 activities took place in 147 countries to reach an estimated 100 million people"), the most important goals are to be followed by the IDL, including: raising social awareness, education, showing the influence of photonics on culture and art, promoting foreign cooperation and the important role of conducting basic research. As a result, it will lead to the creation of new solutions based on photonic technology, which has resulted in increased energy efficiency and improved quality of our life.

Survey Results

Basic scientific research generates knowledge that has intrinsic value which is independent of future applications. Basic research may also lead to practical benefits, such as a new drug or diagnostic method.  Building on our previous study of basic biomedical and biological researchers at Harvard, we present findings from a new survey of similar scientists from three countries.  This survey asked about the scientists’ motivations, goals and perspectives along with their attitudes concerning  policies designed to increase both the practical (i.e. public health) benefits of basic research as well as their own personal satisfaction. Close to 900 basic investigators responded to the survey; results corroborate the main findings from the previous survey of Harvard scientists.  In addition, we find that most bioscientists disfavor present policies that require a discussion of the public health potential of their proposals in grants but generally favor softer policies aimed at increasing the quality of work and the potential practical benefits of basic research. In particular, bioscientists are generally supportive of those policies entailing the organization of more meetings between scientists and the general public, the organization of more academic discussion about the role of scientists in the society, and the implementation of a “basic bibliography” for each new approved drug.

Interventional Pain Management

Background: Appropriately developed practice guidelines present statements of best practice based on a thorough evaluation of the evidence from published studies on the outcomes of treatments, which include the application of multiple methods for collecting and evaluating evidence for a wide range of clinical interventions and disciplines. However, the guidelines are neither infallible, nor a substitute for clinical judgment. While the guideline development process is a complex phenomenon, conflict of interest in guideline development and inappropriate methodologies must be avoided. It has been alleged that the guidelines by the American College of Occupational and Environmental Medicine (ACOEM) prevent injured workers from receiving the majority of medically necessary and appropriate interventional pain management services. An independent critical appraisal of both chapters of the ACOEM guidelines showed startling findings with a conclusion that these guidelines may not be applied in patient care as they scored below 30% in the majority of evaluations utilizing multiple standardized criteria. Objective: To reassess the evidence synthesis for the ACOEM guidelines for the low back pain and chronic pain chapters utilizing an expanded methodology, which includes the criteria included in the ACOEM guidelines with the addition of omitted literature and application of appropriate criteria. Methods: For reassessment, randomized trials were utilized as it was in the preparation of the guidelines. In this process, quality of evidence was assessed and recommendations were made based on grading recommendations of Guyatt et al. The level of evidence was determined utilizing the quality of evidence criteria developed by the U.S. Preventive Services Task Force (USPSTF), as well as the outdated quality of evidence criteria utilized by ACOEM in the guideline preparation. Methodologic quality of each individual article was assessed utilizing the Agency for Healthcare Research and Quality (AHRQ) methodologic assessment criteria for diagnostic interventions and Cochrane methodologic quality assessment criteria for therapeutic interventions. Results: The results of reassessment are vastly different from the conclusions derived by the ACOEM guidelines. The differences in strength of rating for the diagnosis of discogenic pain by provocation discography and facet joint pain by diagnostic facet joint nerve blocks is established with strong evidence. Therapeutic cervical and lumbar medial branch blocks and radiofrequency neurolysis, therapeutic thoracic medial branch blocks, cervical interlaminar epidural steroid injections, caudal epidural steroid injections, lumbar transforaminal epidural injections, percutaneous and endoscopic adhesiolysis, and spinal cord stimulation qualified for moderate to strong evidence. Additional insight is also provided for evidence rating for intradiscal electrothermal therapy (IDET), automated percutaneous disc decompression, and intrathecal implantables. Conclusion: The reassessment and reevaluation of the low back and chronic pain chapters of the ACOEM guidelines present results that are vastly different from the published and proposed guidelines. Contrary to ACOEM’s conclusions of insufficient evidence for most interventional techniques, the results illustrate moderate to strong evidence for most diagnostic and therapeutic interventional techniques.

For predicting the results of sparging processes to understand how much metal can be reduced from oxide melt, a method of thermodynamic modelling has been developed that ensures approximation to real systems in which the metallic phase and gases are removed from the liquid at a certain interval. The key principle of this method is that equilibrium is determined for every single portion of introduced gas, and the concentration of oxides of the reduced metals in each cycle is taken from the previous data. Such approach enables a very close simulation of real processes so that one can have an idea about the quality of reactions taking place in pyrometallurgical units. When the thermodynamic modelling method was applied to the processes of iron and nickel reduction, the obtained results well matched the experimental data. A comparative analysis was carried out to understand how the temperature T and the amount of introduced gas VСО or VН2 influence the process of zinc reduction from oxide melt. For the purposes of modelling, a B2O3 – CaO – ZnO melt was used with the B2O3/CaO ratio equal to 3 (which corresponds to the eutectic composition) and with the initial ZnO concentration in the range from 3 to 12 %; the temperature range used was 1273–1673 K. The concentration of zinc oxide СZnO in the melt, as well as the reduction degree Zn were analyzed. The correlation dependences СZnO, φZn = f(C0, T, VCO or VH2) are presented in the form of second order polynomials. Reduction of zinc with hydrogen is a more intense process than when zinc is reduced with carbon monoxide. Therefore, less gas is required to reach a similar reduction degree. A higher temperature facilitates the reduction of zinc while less СО or Н2 is required to achieve the target reduction degree φZn. Irrespective of the initial composition of the melt, it takes 1.5 times less hydrogen that carbon monoxide to obtain the unit mass of zinc with the process temperature being the same. The obtained data explain the changing zinc distillation performance when changing the temperature. The established relationships between CZnO and φZn and the temperature and the amount of introduced gas are useful for predicting the zinc distillation performance and can be used as basic relationships for analyzing experimental data. This research was funded by the Russian Foundation for Basic Research under the Project No. 18-29-24093мк.
