The article presents selected results of research on the primary structure of a new generation of cobalt-based Co-20Ni-10Al-5Mo-2Nb superalloys. Research on this group of materials was started in 2006 by J. Sato. These materials are anticipated to be able to replace nickel-based superalloys in the future due to their superior elevated temperature properties compared to the nickel-based superalloys. Today, γ’ nickel-based superalloys are still unrivalled in aerospace applications, however, cobalt-based superalloys are a response to their existing limitations, which do not allow the current pace of aircraft engine development to be maintained.

Education is an important factor in human life. According to Ki Hajar Dewantara, education is a civilizing process that a business gives high values ??to the new generation in a society that is not only maintenance but also with a view to promote and develop the culture of the nobility toward human life. Education is a human investment that can be used now and in the future. One other important factor in supporting human life in addition to education, which is technology. In this globalization era, technology has touched every joint of human life. The combination of these two factors will be a new innovation in the world of education. The innovation has been implemented by Raharja College, namely the use of the method iLearning (Integrated Learning) in the learning process. Where such learning has been online based. ILearning method consists of TPI (Ten Pillars of IT iLearning). Rinfo is one of the ten pillars, where it became an official email used by the whole community’s in Raharja College to communicate with each other. Rinfo is Gmail, which is adapted from the Google platform with typical raharja.info as its domain. This Rinfo is a medium of communication, as well as a tool to support the learning process in Raharja College. Because in addition to integrated with TPi, this Rinfo was connected also support with other learning tools, such as Docs, Drive, Sites, and other supporting tools.

This paper deals with a perceived conflicting paradox between consumerism and sustainability among top marketing executives of three purposely selected corporations, where each company represent a current organizational paradigm: the functional, the human radical and the interpretative. A case study methodology, based on in depth interviews, combined with a comprehensive bibliographic research, enabled to address how the planet limitations to provide resources can influence business strategies.  Functional paradigm companies, for example, pursue infinite growth while we live in a finite planet. The question is if the Marketing Department of those companies in the different organizational paradigms have a role in providing inputs in the strategic long term planning. Furthermore, if the marketing discipline in the academic environment influence decision makers that participate on the companies’ business planning to shape the future in a perceived environment in 2017 where consumerism is posed in the against road of the planet sustainability. The study revealed that, the Marketing Department has limited power or voice to influence business decisions. On the other hand, ‘greener’ initiatives like Social Marketing, Green Marketing and Sustainable Marketing has potential to either evolve to or incorporate a new discipline concept, so called in this paper as ‘Conscious Marketing’. This opportunity should be kicked off at the academic level in Universities and Business Schools that may reinforce the relevance of the theme and help to build in the students, a new generation of professionals, the knowledge that we live in a finite planet with limited resources and that the humanity need to revisit its consumption standards to ensure living conditions to the future generations.

Like in many other provinces, during the Habsburg period, the main point of orientation for Galicia was Vienna. This also applies to architecture and urban development. Galicia’s technical elite applied the theoretical and practical experience it gathered in Vienna to the towns and cities of this northeastern Crown land. Ignacy Drexler, born in 1878 in the Austro-Hungarian Lemberg, was a representative of a new generation of engineers and architects who did not necessarily have to spend time in the imperial capital to earn their spurs. Increasingly, besides the more or less obligatory stay in Vienna, other European countries became points of reference. Drexler did not live to see the realization of important aspects of his comprehensive plan for the city, but his ideas and the data he compiled were indispensable for the future development of his hometown. They shape urban planning in Lviv to this day.

The final chapter touches back on the stories of veteran activists Wendy Barranco, Phoenix Johnson, Monique Salhab, Monisha Ríos, Stephen Funk, and Brittany Ramos DeBarros to consider the future of Veterans For Peace and About Face within the larger field of national and international movements for peace and social justice. The chapter touches on the state of the current intergenerational dialogue taking place in these organizations, and ends with a critical analysis of how the intersectional praxis of a new generation of progressive activists holds the promise of bridging the struggle against militarism and war with other large issues of the day, including climate change, global pandemics, and the continuing violence of economic, racial, gender, and sexual injustice.

PurposeThe rapid urbanization of China brings in large number of migrant workers coming from rural areas. With the perspective of social integration, this study reviews the findings about economic livelihood, social integration and health related to migrant workers since China initiated economic reform. We show that (1) though the economic wellbeing of migrant workers has been improved significantly after they moved to cities, their economic standing is still lower than local residents; (2) though there is progress of social integration between migrant workers and local residents, conflicts and challenges due to the competitions in employment and the sharing of community resource are still commonly found; (3) the disadvantaged status of health is very common among migrant workers and (4) women and the new generation in migration have more disadvantages in the social transition. We suggest that issues of equal rights between migrant workers and local residents should be discussed in the future as more migrant workers intend to stay in cities for long-term.Design/methodology/approachThe methodology is literature reviews based on the current studies about migrant, migration and policy. The first category of literature is the research field on China's migration and urbanization to describe the whole context of migrant workers. The second is research field on detailed issues about migrant workers and the last field is policy issues about the welfare and needs among migrant workers.FindingsWe find that (1) though the economic wellbeing of migrant workers has been improved significantly after they moved to cities, their economic standing is still lower than local residents; (2) though there are progress of social integration between migrant workers and local residents, conflicts and challenges due to the competitions in employment and the sharing of community resource are still commonly found; (3) the disadvantaged status of health is very common among migrant workers and (4) women and the new generation in migration face more disadvantages in the social transition.Research limitations/implicationsThere are some limitations in the current research: (1) the review focuses on the majority of migrant workers to reveal the general picture about the living, developing and rights among migrant workers, but is still lacking in dealing with some special and disadvantaged groups. (2) More international issues related to migrant workers should be discussed in the future considering that China's labor market is becoming more and more global.Social implicationsFirst, the conclusion about the economic and social integration among migrant workers indicates that more equal welfare services, including resident services, commence services, medical services etc. should be included in the municipal managements considering that Chinese cities will be the combination of local residents and migrant residents. Second, the conclusion about the women and children indicates that the future public services targeted at the disadvantaged population should focus on migrant members due to the second generation of migrant workers will be one of the mainstream population in future China's cities.Originality/valueThis study gives general views on migrant workers in current China. The findings in this review conclude the main development and improvements among tens of millions of migrant workers in Chinese cities. Meanwhile, we also conclude that there are still many disadvantaged and marginalized sub-groups in migration who are suffering from less welfares and rights in urban lives. More detailed and equal rights and public services should be considered and implemented in the fast urbanization taking place.

A great amount of research is being conducted to incorporate smart material actuators in aerospace applications such as (1) turbo fan engines (2) servo flap actuators for helicopter rotor control. For example, a piezoelectric stack actuator, coupled with mechanical or hydraulic amplification could provide the actuation required for the variable pitch fan system with a potentially higher level of reliability. In addition, piezoelectric actuation system could do so at a lower overall weight. However, there are limitations with existing piezoelectric stack actuators relative to power requirements. Therefore, a new approach has been investigated to improve these characteristics in order for piezoelectric stacks to be a feasible solution for these types of large scale applications. A new configuration involving dielectric, conductor, piezoelectric material in a particular sequence of stack actuation is examined and experimented. A nonlinear lumped parameter model of a piezoelectric stack has been developed to describe the behavior for the purpose of control actuation analysis.
